Foam washing was compared as an alternative to stone washing in terms of sustainability and performance parameters. For this purpose, seven different denim fabrics, which are both stone washed and foam washed separately in 3 different washing durations (30-60-90 mins), were compared. In the study, the same fabrics were processed with both foam and stone separately. The washing process steps were reviewed, and their water consumption values were compared. After washing, a total of 42 fabric samples were obtained, and tensile strength, tear strength, abrasion, weight loss after abrasion, rubbing fastness, color fastness tests were carried out on the fabric samples. The obtained test results were reviewed and evaluated. As a result of tests, it has been observed that the performance of foam washed fabrics in terms of tensile, tear strength and rubbing fastness test results are better than stone washed fabrics, and it has been seen that foam washed fabrics' color fastness test results are as stone washed. As a result of all these tests, it can be seen that foam washing is an alternative to stone washing due to its performance parameters and its sustainability performance with less water usage. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=denim%20fabrics" title="denim fabrics">denim fabrics</a>, <a href="https://publications.waset.org/abstracts/search?q=denim%20washing" title=" denim washing"> denim washing</a>, <a href="https://publications.waset.org/abstracts/search?q=foam%20washing" title=" foam washing"> foam washing</a>, <a href="https://publications.waset.org/abstracts/search?q=performance%20properties" title=" performance properties"> performance properties</a>, <a href="https://publications.waset.org/abstracts/search?q=stone%20washing" title=" stone washing"> stone washing</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainability" title=" sustainability"> sustainability</a> </p> <a href="https://publications.waset.org/abstracts/177884/investigation-of-physical-performance-of-denim-fabrics-washed-with-sustainable-foam-washing-process" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/177884.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">71</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8948</span> The Effect of Pulsator on Washing Performance in a Front-Loading Washer</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eung%20Ryeol%20Seo">Eung Ryeol Seo</a>, <a href="https://publications.waset.org/abstracts/search?q=Hee%20Tae%20Lim"> Hee Tae Lim</a>, <a href="https://publications.waset.org/abstracts/search?q=Eunsuk%20Bang"> Eunsuk Bang</a>, <a href="https://publications.waset.org/abstracts/search?q=Soon%20Cheol%20Kweon"> Soon Cheol Kweon</a>, <a href="https://publications.waset.org/abstracts/search?q=Jeoung-Kyo%20Jeoung"> Jeoung-Kyo Jeoung</a>, <a href="https://publications.waset.org/abstracts/search?q=Ji-Hoon%20Choic"> Ji-Hoon Choic</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The object of this study is to investigate the effect of pulsator on washing performance quantitatively for front-loading washer.

Especially, the stain removal is significantly important in the Far East market, where the high percentage of the consumers use the top load washing machines as washing appliance. They use all pretreatment methods (i.e. soaking, prewash, and heavy functions) to eliminate the stains from their clothes. Therefore, with this study it is aimed to study experimentally the stain removal performance of 3 different Top-Loading washing machines of the Far East market with 24 different types of stains which are mostly related to Far East culture. In the meanwhile, the mechanical damge on laundry is examined for each machine to see the mechanical effect of the related stain programs on the textile load of the machines. The test machines vary according to have a heater, moving part(s)on their impeller, and to be in different height/width ratio of the drum. The results indicate that decreasing the water level inside the washing machine might result in better soil removal as well as less textile damage. Beside this, the experimental results reveal that heating has the main effect on stain removal. Two-step (or delayed) heating and a lower amount of water can also be considered as the further parameters <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=laundry" title="laundry">laundry</a>, <a href="https://publications.waset.org/abstracts/search?q=washing%20machine" title=" washing machine"> washing machine</a>, <a href="https://publications.waset.org/abstracts/search?q=top%20load%20washing%20machine" title=" top load washing machine"> top load washing machine</a>, <a href="https://publications.waset.org/abstracts/search?q=stain%20removal" title=" stain removal"> stain removal</a>, <a href="https://publications.waset.org/abstracts/search?q=textile%20damage" title=" textile damage"> textile damage</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20textile%20damage" title=" mechanical textile damage"> mechanical textile damage</a> </p> <a href="https://publications.waset.org/abstracts/152389/experimental-investigation-of-stain-removal-performance-of-different-types-of-top-load-washing-machines-with-textile-mechanical-damage-consideration" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/152389.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">124</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8946</span> Microfiber Release During Laundry Under Different Rinsing Parameters</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fulya%20Asena%20Ulu%C3%A7">Fulya Asena Uluç</a>, <a href="https://publications.waset.org/abstracts/search?q=Ehsan%20Tuzcuo%C4%9Flu"> Ehsan Tuzcuoğlu</a>, <a href="https://publications.waset.org/abstracts/search?q=Song%C3%BCl%20Bayraktar"> Songül Bayraktar</a>, <a href="https://publications.waset.org/abstracts/search?q=Burak%20Koca"> Burak Koca</a>, <a href="https://publications.waset.org/abstracts/search?q=Alper%20G%C3%BCrarslan"> Alper Gürarslan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Microplastics are contaminants that are widely distributed in the environment with a detrimental ecological effect. Besides this, recent research has proved the existence of microplastics in human blood and organs. Microplastics in the environment can be divided into two main categories: primary and secondary microplastics. Primary microplastics are plastics that are released into the environment as microscopic particles. On the other hand, secondary microplastics are the smaller particles that are shed as a result of the consumption of synthetic materials in textile products as well as other products. Textiles are the main source of microplastic contamination in aquatic ecosystems. Laundry of synthetic textiles (34.8%) accounts for an average annual discharge of 3.2 million tons of primary microplastics into the environment. Recently, microfiber shedding from laundry research has gained traction. However, no comprehensive study was conducted from the standpoint of rinsing parameters during laundry to analyze microfiber shedding. The purpose of the present study is to quantify microfiber shedding from fabric under different rinsing conditions and determine the effective rinsing parameters on microfiber release in a laundry environment. In this regard, a parametric study is carried out to investigate the key factors affecting the microfiber release from a front-load washing machine. These parameters are the amount of water used during the rinsing step and the spinning speed at the end of the washing cycle. Minitab statistical program is used to create a design of the experiment (DOE) and analyze the experimental results. Tests are repeated twice and besides the controlled parameters, other washing parameters are kept constant in the washing algorithm. At the end of each cycle, released microfibers are collected via a custom-made filtration system and weighted with precision balance. The results showed that by increasing the water amount during the rinsing step, the amount of microplastic released from the washing machine increased drastically. Also, the parametric study revealed that increasing the spinning speed results in an increase in the microfiber release from textiles. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=front%20load" title="front load">front load</a>, <a href="https://publications.waset.org/abstracts/search?q=laundry" title=" laundry"> laundry</a>, <a href="https://publications.waset.org/abstracts/search?q=microfiber" title=" microfiber"> microfiber</a>, <a href="https://publications.waset.org/abstracts/search?q=microfiber%20release" title=" microfiber release"> microfiber release</a>, <a href="https://publications.waset.org/abstracts/search?q=microfiber%20shedding" title=" microfiber shedding"> microfiber shedding</a>, <a href="https://publications.waset.org/abstracts/search?q=microplastic" title=" microplastic"> microplastic</a>, <a href="https://publications.waset.org/abstracts/search?q=pollution" title=" pollution"> pollution</a>, <a href="https://publications.waset.org/abstracts/search?q=rinsing%20parameters" title=" rinsing parameters"> rinsing parameters</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainability" title=" sustainability"> sustainability</a>, <a href="https://publications.waset.org/abstracts/search?q=washing%20parameters" title=" washing parameters"> washing parameters</a>, <a href="https://publications.waset.org/abstracts/search?q=washing%20machine" title=" washing machine"> washing machine</a> </p> <a href="https://publications.waset.org/abstracts/158164/microfiber-release-during-laundry-under-different-rinsing-parameters" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/158164.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">97</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8945</span> Conceptual Design of a Customer Friendly Variable Volume and Variable Spinning Speed Washing Machine</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=C.%20A.%20Akaash%20Emmanuel%20Raj">C.

Thanks to the EEP, the energy consumption of a washing machine as one of the most energy-consuming home appliances can shrink considerably, while its washing performance and the textile hygiene should remain almost unchanged. Here in, the goal of the present study is to achieve an optimum EEP algorithm providing excellent textile hygiene results as well as cleaning performance in a domestic washing machine. In this regard, steam-pretreated cold wash approach with a combination of innovative algorithm solution in a relatively short washing cycle duration was implemented. For the parametric study, steam exposure time, washing load, total water consumption, main-washing time, and spinning rpm as the significant parameters affecting the textile hygiene and cleaning performance were investigated within a Design of Experiment study using Minitab 2021 statistical program. For the textile hygiene studies, specific loads containing the contaminated cotton carriers with Escherichia coli, Staphylococcus aureus, and Pseudomonas aeruginosa bacteria were washed. Then, the microbial removal performance of the designed programs was expressed as log reduction calculated as a difference of microbial count per ml of the liquids in which the cotton carriers before and after washing. For the cleaning performance studies, tests were carried out with various types of detergents and EMPA Standard Stain Strip. According to the results, the optimum EEP program provided an excellent hygiene performance of more than 2 log reduction of microorganism and a perfect Washing Efficiency Index (Iw) of 1.035, which is greater than the value specified by EU ecodesign regulation 2019/2023. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=washing%20machine" title="washing machine">washing machine</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20efficient%20programs" title=" energy efficient programs"> energy efficient programs</a>, <a href="https://publications.waset.org/abstracts/search?q=hygiene" title=" hygiene"> hygiene</a>, <a href="https://publications.waset.org/abstracts/search?q=washing%20efficiency%20index" title=" washing efficiency index"> washing efficiency index</a>, <a href="https://publications.waset.org/abstracts/search?q=microorganism" title=" microorganism"> microorganism</a>, <a href="https://publications.waset.org/abstracts/search?q=escherichia%20coli" title=" escherichia coli"> escherichia coli</a>, <a href="https://publications.waset.org/abstracts/search?q=staphylococcus%20aureus" title=" staphylococcus aureus"> staphylococcus aureus</a>, <a href="https://publications.waset.org/abstracts/search?q=pseudomonas%20aeruginosa" title=" pseudomonas aeruginosa"> pseudomonas aeruginosa</a>, <a href="https://publications.waset.org/abstracts/search?q=laundry" title=" laundry"> laundry</a> </p> <a href="https://publications.waset.org/abstracts/154362/parametric-study-of-a-washing-machine-to-develop-an-energy-efficient-program-regarding-the-enhanced-washing-efficiency-index-and-micro-organism-removal-performance" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/154362.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">135</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8943</span> A Laundry Algorithm for Colored Textiles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=H.%20E.%20Budak">H.

During the experimental work, bleached knitted single jersey fabric made of 100% cotton and dyed with reactive dyestuff was utilized, since according to a conducted survey textiles made of cotton are the most demanded textile products in the textile market by the textile consumers and for coloration of textiles reactive dyestuffs are the ones that are the most commonly used in the textile industry for dyeing cotton-made products. Therefore, the fabric used in this study was selected and purchased in accordance with the survey results. The fabric samples cut out of this fabric were dyed with different dyeing parameters by using Remazol Brilliant Red 3BS dyestuff in Gyrowash machine at laboratory conditions. From the alternative reactive-dyed cotton fabric samples, the ones that have high tendency to color loss were determined and examined. Accordingly, the parameters of the dyeing process used for these fabric samples were evaluated and the dyeing process which was chosen to be used for causing high tendency to color loss for the cotton fabrics was determined in order to reveal the level of improvement in color loss during this study clearly. Afterwards, all of the untreated fabric samples cut out of the fabric purchased were dyed with the dyeing process selected. When dyeing process was completed, an experimental design was created for the laundering process by using Minitab® program considering temperature, time and mechanical action as parameters. All of the washing experiments were performed in domestic washing machine. 16 washing experiments were performed with 8 different experimental conditions and 2 repeats for each condition. After each of the washing experiments, water samples of the main wash of the laundering process were measured with UV spectrophotometer. The values obtained were compared with the calibration curve of the materials used for the dyeing process. The results of the washing experiments were statistically analyzed with Minitab® program. According to the results, the most suitable washing algorithm to be used in terms of the parameters temperature, time and mechanical action for domestic washing machines for minimizing fabric color loss was chosen. The laundry algorithm proposed in this study have the ability of minimalizing the problem of color loss of colored textiles in washing machines by eliminating the negative effects of the parameters of laundering process on color of textiles without compromising the fundamental effects of basic cleaning action being performed properly. Therefore, since fabric color loss is minimized with this washing algorithm, dyestuff residuals will definitely be lower in the grey water released from the laundering process. In addition to this, with this laundry algorithm it is possible to wash and clean other types of textile products with proper cleaning effect and minimized color loss. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=color%20loss" title="color loss">color loss</a>, <a href="https://publications.waset.org/abstracts/search?q=laundry%20algorithm" title=" laundry algorithm"> laundry algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=textiles" title=" textiles"> textiles</a>, <a href="https://publications.waset.org/abstracts/search?q=domestic%20washing%20process" title=" domestic washing process"> domestic washing process</a> </p> <a href="https://publications.waset.org/abstracts/43593/a-laundry-algorithm-for-colored-textiles" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43593.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">357</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8942</span> Forensic Medical Capacities of Research of Saliva Stains on Physical Evidence after Washing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Saule%20Mussabekova">Saule Mussabekova</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Recent advances in genetics have allowed increasing acutely the capacities of the formation of reliable evidence in conducting forensic examinations. Thus, traces of biological origin are important sources of information about a crime. Currently, around the world, sexual offenses have increased, and among them are those in which the criminals use various detergents to remove traces of their crime. A feature of modern synthetic detergents is the presence of biological additives - enzymes. Enzymes purposefully destroy stains of biological origin. To study the nature and extent of the impact of modern washing powders on saliva stains on the physical evidence, specially prepared test specimens of different types of tissues to which saliva was applied have been examined. Materials and Methods: Washing machines of famous manufacturers of household appliances have been used with different production characteristics and advertised brands of washing powder for test washing. Over 3,500 experimental samples were tested. After washing, the traces of saliva were identified using modern research methods of forensic medicine. Results: The influence was tested and the dependence of the use of different washing programs, types of washing machines and washing powders in the process of establishing saliva trace and identify of the stains on the physical evidence while washing was revealed. The results of experimental and practical expert studies have shown that in most cases it is not possible to draw the conclusions in the identification of saliva traces on physical evidence after washing. This is a consequence of the effect of biological additives and other additional factors on traces of saliva during washing. Conclusions: On the basis of the results of the study, the feasibility of saliva traces of the stains on physical evidence after washing is established. The use of modern molecular genetic methods makes it possible to partially solve the problems arising in the study of unlaundered evidence. Additional study of physical evidence after washing facilitates detection and investigation of sexual offenses against women and children. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=saliva%20research" title="saliva research">saliva research</a>, <a href="https://publications.waset.org/abstracts/search?q=modern%20synthetic%20detergents" title=" modern synthetic detergents"> modern synthetic detergents</a>, <a href="https://publications.waset.org/abstracts/search?q=laundry%20detergents" title=" laundry detergents"> laundry detergents</a>, <a href="https://publications.waset.org/abstracts/search?q=forensic%20medicine" title=" forensic medicine"> forensic medicine</a> </p> <a href="https://publications.waset.org/abstracts/61266/forensic-medical-capacities-of-research-of-saliva-stains-on-physical-evidence-after-washing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/61266.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">216</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8941</span> Control of Biofilm Formation and Inorganic Particle Accumulation on Reverse Osmosis Membrane by Hypochlorite Washing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Masaki%20Ohno">Masaki Ohno</a>, <a href="https://publications.waset.org/abstracts/search?q=Cervinia%20Manalo"> Cervinia Manalo</a>, <a href="https://publications.waset.org/abstracts/search?q=Tetsuji%20Okuda"> Tetsuji Okuda</a>, <a href="https://publications.waset.org/abstracts/search?q=Satoshi%20Nakai"> Satoshi Nakai</a>, <a href="https://publications.waset.org/abstracts/search?q=Wataru%20Nishijima"> Wataru Nishijima</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Reverse osmosis (RO) membranes have been widely used for desalination to purify water for drinking and other purposes. Although at present most RO membranes have no resistance to chlorine, chlorine-resistant membranes are being developed. Therefore, direct chlorine treatment or chlorine washing will be an option in preventing biofouling on chlorine-resistant membranes. Furthermore, if particle accumulation control is possible by using chlorine washing, expensive pretreatment for particle removal can be removed or simplified. The objective of this study was to determine the effective hypochlorite washing condition required for controlling biofilm formation and inorganic particle accumulation on RO membrane in a continuous flow channel with RO membrane and spacer. In this study, direct chlorine washing was done by soaking fouled RO membranes in hypochlorite solution and fluorescence intensity was used to quantify biofilm on the membrane surface. After 48 h of soaking the membranes in high fouling potential waters, the fluorescence intensity decreased to 0 from 470 using the following washing conditions: 10 mg/L chlorine concentration, 2 times/d washing interval, and 30 min washing time. The chlorine concentration required to control biofilm formation decreased as the chlorine concentration (0.5–10 mg/L), the washing interval (1–4 times/d), or the washing time (1–30 min) increased. For the sample solutions used in the study, 10 mg/L chlorine concentration with 2 times/d interval, and 5 min washing time was required for biofilm control. The optimum chlorine washing conditions obtained from soaking experiments proved to be applicable also in controlling biofilm formation in continuous flow experiments. Moreover, chlorine washing employed in controlling biofilm with suspended particles resulted in lower amounts of organic (0.03 mg/cm<sup>2</sup>) and inorganic (0.14 mg/cm<sup>2</sup>) deposits on the membrane than that for sample water without chlorine washing (0.14 mg/cm<sup>2</sup> and 0.33 mg/cm<sup>2</sup>, respectively). The amount of biofilm formed was 79% controlled by continuous washing with 10 mg/L of free chlorine concentration, and the inorganic accumulation amount decreased by 58% to levels similar to that of pure water with kaolin (0.17 mg/cm<sup>2</sup>) as feed water. These results confirmed the acceleration of particle accumulation due to biofilm formation, and that the inhibition of biofilm growth can almost completely reduce further particle accumulation. In addition, effective hypochlorite washing condition which can control both biofilm formation and particle accumulation could be achieved. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=reverse%20osmosis" title="reverse osmosis">reverse osmosis</a>, <a href="https://publications.waset.org/abstracts/search?q=washing%20condition%20optimization" title=" washing condition optimization"> washing condition optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=hypochlorous%20acid" title=" hypochlorous acid"> hypochlorous acid</a>, <a href="https://publications.waset.org/abstracts/search?q=biofouling%20control" title=" biofouling control"> biofouling control</a> </p> <a href="https://publications.waset.org/abstracts/36473/control-of-biofilm-formation-and-inorganic-particle-accumulation-on-reverse-osmosis-membrane-by-hypochlorite-washing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36473.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">351</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8940</span> Persistence of DNA on Clothes Contaminated by Semen Stains after Washing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ashraf%20Shebl">Ashraf Shebl</a>, <a href="https://publications.waset.org/abstracts/search?q=Bassam%20Garah"> Bassam Garah</a>, <a href="https://publications.waset.org/abstracts/search?q=Radah%20Youssef"> Radah Youssef</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Sexual assault is usually a hidden crime where the only witnesses are the victim and the assailant. For a variety of reasons, even the victim may be unable to provide a detailed account of the assault or the identity of the perpetrator. Often the case history deteriorates into one person’s word against another. With such limited initial information, the physical and biological evidence collected from the victim, from the crime scene, and from the suspect will play a pivotal role in the objective and scientific reconstruction of the events in question. The aim of work is to examine whether DNA profiles could be recovered from repeated washed clothes after contaminated by semen stains. Fresh semen about 1ml. ( <1 h old) taken from donor was deposited on four types of clothes (cotton, silk, polyester, and jeans). Then leave to dry in room temperature and washed by washing machine at temperature (30°C-60°C) and by hand washing. Some items of clothing were washed once, some twice and others three times. DNA could be extracted from some of these samples even after multiple washing. This study demonstrates that complete DNA profiles can be obtained from washed semen stains on different types of clothes, even after many repeated washing. These results indicated that clothes of the victims must be examined even if they were washed many times. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sexual%20assault" title="sexual assault">sexual assault</a>, <a href="https://publications.waset.org/abstracts/search?q=DNA" title=" DNA"> DNA</a>, <a href="https://publications.waset.org/abstracts/search?q=persistence" title=" persistence"> persistence</a>, <a href="https://publications.waset.org/abstracts/search?q=clothes" title=" clothes"> clothes</a> </p> <a href="https://publications.waset.org/abstracts/86168/persistence-of-dna-on-clothes-contaminated-by-semen-stains-after-washing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/86168.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">198</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8939</span> Parametrical Analysis of Stain Removal Performance of a Washing Machine: A Case Study of Sebum</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ozcan%20B.">Ozcan B.</a>, <a href="https://publications.waset.org/abstracts/search?q=Koca%20B."> Koca B.</a>, <a href="https://publications.waset.org/abstracts/search?q=Tuzcuoglu%20E."> Tuzcuoglu E.</a>, <a href="https://publications.waset.org/abstracts/search?q=Cavusoglu%20S."> Cavusoglu S.</a>, <a href="https://publications.waset.org/abstracts/search?q=Efe%20A."> Efe A.</a>, <a href="https://publications.waset.org/abstracts/search?q=Bayraktar%20S."> Bayraktar S.</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A washing machine is mainly used for removing any types of dirt and stains and also eliminating malodorous substances from textile surfaces. Stains originate from various sources from the human body to environmental contamination. Therefore, there are various methods for removing them. They are roughly classified into four different groups: oily (greasy) stains, particulate stains, enzymatic stains and bleachable (oxidizable) stains. Oily stains on clothes surfaces are a common result of being in contact with organic substances of the human body (e.g. perspiration, skin shedding and sebum) or by being exposed to an oily environmental pollutant (e.g. oily foods). Studies showed that human sebum is major component of oily soil found on the garments, and if it is aged under the several environmental conditions, it can generate obstacle yellow stains on the textile surface. In this study, a parametric study was carried out to investigate the key factors affecting the cleaning performance (specifically sebum removal performance) of a washing machine. These parameters are mechanical agitation percentage of tumble, consumed water and total washing period. A full factorial design of the experiment is used to capture all the possible parametric interactions using Minitab 2021 statistical program. Tests are carried out with commercial liquid detergent and 2 different types of sebum-soiled cotton and cotton + polyester fabrics. Parametric results revealed that for both test samples, increasing the washing time and the mechanical agitation could lead to a much better removal result of sebum. However, for each sample, the water amount had different outcomes. Increasing the water amount decreases the performance of cotton + polyester fabrics, while it is favorable for cotton fabric. Besides this, it was also discovered that the type of textile can greatly affect the sebum removal performance. Results showed that cotton + polyester fabrics are much easier to clean compared to cotton fabric <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=laundry" title="laundry">laundry</a>, <a href="https://publications.waset.org/abstracts/search?q=washing%20machine" title=" washing machine"> washing machine</a>, <a href="https://publications.waset.org/abstracts/search?q=low-temperature%20washing" title=" low-temperature washing"> low-temperature washing</a>, <a href="https://publications.waset.org/abstracts/search?q=cold%20wash" title=" cold wash"> cold wash</a>, <a href="https://publications.waset.org/abstracts/search?q=washing%20efficiency%20index" title=" washing efficiency index"> washing efficiency index</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainability" title=" sustainability"> sustainability</a>, <a href="https://publications.waset.org/abstracts/search?q=cleaning%20performance" title=" cleaning performance"> cleaning performance</a>, <a href="https://publications.waset.org/abstracts/search?q=stain%20removal" title=" stain removal"> stain removal</a>, <a href="https://publications.waset.org/abstracts/search?q=oily%20soil" title=" oily soil"> oily soil</a>, <a href="https://publications.waset.org/abstracts/search?q=sebum" title=" sebum"> sebum</a>, <a href="https://publications.waset.org/abstracts/search?q=yellowing" title=" yellowing"> yellowing</a> </p> <a href="https://publications.waset.org/abstracts/154900/parametrical-analysis-of-stain-removal-performance-of-a-washing-machine-a-case-study-of-sebum" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/154900.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">143</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8938</span> The Effect of Oxidation Stability Improvement in Calophyllum Inophyllum Palm Oil Methyl Ester Production</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Natalina">Natalina</a>, <a href="https://publications.waset.org/abstracts/search?q=Hwai%20Chyuan%20Onga"> Hwai Chyuan Onga</a>, <a href="https://publications.waset.org/abstracts/search?q=W.%20T.%20Chonga"> W.

Variety of feedstocks and biodiesel production process resulted many variation of biodiesel oxidation stability. The current study relates to investigation of the impact of fatty acid composition that caused by natural and production process of calophyllum inophyllum palm oil methyl ester that correlated with improvement of biodiesel oxidation stability. Firstly, biodiesel was produced from crude oil of palm oil, calophyllum inophyllum and mixing of calophyllum inophyllum and palm oil. The production process of calophyllum inophyllum palm oil methyl ester (CIPOME) was divided by including washing process and without washing. Secondly, the oxidation stability was measured from the palm oil methyl ester (POME), calophyllum inophyllum methyl ester (CIME), CIPOME with washing process and CIPOME without washing process. Then, in order to find the differences of fatty acid compositions all of the biodiesels were measured by gas chromatography analysis. It was found that mixing calophyllum inophyllum into palm oil increased the oxidation stability. Washing process influenced the CIPOME fatty acid composition, and reduction of washing process during the production process gave significant oxidation stability number of CIPOME (38 h to 114 h). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biodiesel" title="biodiesel">biodiesel</a>, <a href="https://publications.waset.org/abstracts/search?q=oxidation%20stability" title=" oxidation stability"> oxidation stability</a>, <a href="https://publications.waset.org/abstracts/search?q=calophyllum%20inophyllum" title=" calophyllum inophyllum"> calophyllum inophyllum</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20content" title=" water content"> water content</a> </p> <a href="https://publications.waset.org/abstracts/39777/the-effect-of-oxidation-stability-improvement-in-calophyllum-inophyllum-palm-oil-methyl-ester-production" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/39777.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">270</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8937</span> Micro Plasma an Emerging Technology to Eradicate Pesticides from Food Surface</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Saiful%20Islam%20Khan">Muhammad Saiful Islam Khan</a>, <a href="https://publications.waset.org/abstracts/search?q=Yun%20Ji%20Kim"> Yun Ji Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Organophosphorus pesticides (OPPs) have been widely used to replace more persistent organochlorine pesticides because OPPs are more soluble in water and decompose rapidly in aquatic systems. Extensive uses of OPPs in modern agriculture are the major cause of the contamination of surface water. Regardless of the advantages gained by the application of pesticides in modern agriculture, they are a threat to the public health environment. With the aim of reducing possible health threats, several physical and chemical treatment processes have been studied to eliminate biological and chemical poisons from food stuff. In the present study, a micro-plasma device was used to reduce pesticides from the surface of food stuff. Pesticide free food items chosen in this study were perilla leaf, tomato, broccoli and blueberry. To evaluate the removal efficiency of pesticides, different washing methods were followed such as soaking with water, washing with bubbling water, washing with plasma-treated water and washing with chlorine water. 2 mL of 2000 ppm pesticide samples, namely, diazinone and chlorpyrifos were individuality inoculated on food surface and was air dried for 2 hours before treated with plasma. Plasma treated water was used in two different manners one is plasma treated water with bubbling the other one is aerosolized plasma treated water. The removal efficiency of pesticides from food surface was studied using HPLC. Washing with plasma treated water, aerosolized plasma treated water and chlorine water shows minimum 72% to maximum 87 % reduction for 4 min treatment irrespective to the types of food items and the types of pesticides sample, in case of soaking and bubbling the reduction is 8% to 48%. Washing with plasma treated water, aerosolized plasma treated water and chlorine water shows somewhat similar reduction ability which is significantly higher comparing to the soaking and bubbling washing system. The temperature effect of the washing systems was also evaluated; three different temperatures were set for the experiment, such as 22°C, 10°C and 4°C. Decreasing temperature from 22°C to 10°C shows a higher reduction in the case of washing with plasma and aerosolized plasma treated water, whereas an opposite trend was observed for the washing with chlorine water. Further temperature reduction from 10°C to 4°C does not show any significant reduction of pesticides, except for the washing with chlorine water. Chlorine water treatment shows lesser pesticide reduction with the decrease in temperature. The color changes of the treated sample were measured immediately and after one week to evaluate if there is any effect of washing with plasma treated water and with chlorine water. No significant color changes were observed for either of the washing systems, except for broccoli washing with chlorine water. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=chlorpyrifos" title="chlorpyrifos">chlorpyrifos</a>, <a href="https://publications.waset.org/abstracts/search?q=diazinone" title=" diazinone"> diazinone</a>, <a href="https://publications.waset.org/abstracts/search?q=pesticides" title=" pesticides"> pesticides</a>, <a href="https://publications.waset.org/abstracts/search?q=micro%20plasma" title=" micro plasma"> micro plasma</a> </p> <a href="https://publications.waset.org/abstracts/139413/micro-plasma-an-emerging-technology-to-eradicate-pesticides-from-food-surface" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/139413.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">187</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8936</span> Removal of Diesel by Soil Washing Technologies Using a Non-Ionic Surfactant</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Carolina%20Guatemala">Carolina Guatemala</a>, <a href="https://publications.waset.org/abstracts/search?q=Josefina%20Barrera"> Josefina Barrera</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A large number of soils highly polluted with recalcitrant hydrocarbons and the limitation of the current bioremediation methods continue being the drawback for an efficient recuperation of these under safe conditions. In this regard, soil washing by degradable surfactants is an alternative option knowing the capacity of surfactants to desorb oily organic compounds. The aim of this study was the establishment of the washing conditions of a soil polluted with diesel, using a nonionic surfactant. A soil polluted with diesel was used. This was collected near to a polluted railway station zone. The soil was dried at room temperature and sieved to a mesh size 10 for its physicochemical and biological characterization. Washing of the polluted soil was performed with surfactant solutions in a 1:5 ratio (5g of soil per 25 mL of the surfactant solution). This was carried out at 28±1 °C and 150 rpm for 72 hours. The factors tested were the Tween 80 surfactant concentration (1, 2, 5 and 10%) and the treatment time. Residual diesel concentration was determined every 24 h. The soil was of a sandy loam texture with a low concentration of organic matter (3.68%) and conductivity (0.016 dS.m- 1). The soil had a pH of 7.63 which was slightly alkaline and a Total Petroleum Hydrocarbon content (TPH) of 11,600 ± 1058.38 mg/kg. The high TPH content could explain the low microbial count of 1.1105 determined as UFC per gram of dried soil. Within the range of the surfactant concentration tested for washing the polluted soil under study, TPH removal increased proportionally with the surfactant concentration. 5080.8 ± 422.2 ppm (43.8 ± 3.64 %) was the maximal concentration of TPH removed after 72 h of contact with surfactant pollution at 10%. Despite the high percentage of hydrocarbons removed, it is assumed that a higher concentration of these could be removed if the washing process is extended or is carried out by stages. Soil washing through the use of surfactants as a desorbing agent was found to be a viable and effective technology for the rapid recovery of soils highly polluted with recalcitrant hydrocarbons. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=diesel" title="diesel">diesel</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrocarbons" title=" hydrocarbons"> hydrocarbons</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20washing" title=" soil washing"> soil washing</a>, <a href="https://publications.waset.org/abstracts/search?q=tween%2080" title=" tween 80"> tween 80</a> </p> <a href="https://publications.waset.org/abstracts/99376/removal-of-diesel-by-soil-washing-technologies-using-a-non-ionic-surfactant" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/99376.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">142</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8935</span> Modelling the Behavior of Commercial and Test Textiles against Laundering Process by Statistical Assessment of Their Performance</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20H.%20Arslan">M.

In accordance with their frequency of use, textile materials are required to be laundered at certain intervals. The medium in which the laundering process takes place have inevitable detrimental physical and chemical effects on textile materials caused by the unique parameters of the process inherently existing. Connatural structures of various textile materials result in many different physical, chemical and mechanical characteristics. Because of their specific structures, these materials have different behaviors against several exterior factors. By modeling the behavior of commercial and test textiles as group-wise against laundering process, it is possible to disclose the relation in between these two groups of materials, which will lead to better understanding of their behaviors in terms of similarities and differences against the washing parameters of the laundering. Thus, the goal of the current research is to examine the behavior of two groups of textile materials as commercial textiles and as test textiles towards the main washing machine parameters during laundering process such as temperature, load quantity, mechanical action and level of water amount by concentrating on shrinkage, pilling, sewing defects, collar abrasion, the other defects other than sewing, whitening and overall properties of textiles. In this study, cotton fabrics were preferred as commercial textiles due to the fact that garments made of cotton are the most demanded products in the market by the textile consumers in daily life. Full factorial experimental set-up was used to design the experimental procedure. All profiles always including all of the commercial and the test textiles were laundered for 20 cycles by commercial home laundering machine to investigate the effects of the chosen parameters. For the laundering process, a modified version of ‘‘IEC 60456 Test Method’’ was utilized. The amount of detergent was altered as 0.5% gram per liter depending on varying load quantity levels. Datacolor 650®, EMPA Photographic Standards for Pilling Test and visual examination were utilized to test and characterize the textiles. Furthermore, in the current study the relation in between commercial and test textiles in terms of their performance was deeply investigated by the help of statistical analysis performed by MINITAB® package program modeling their behavior against the parameters of the laundering process. In the experimental work, the behaviors of both groups of textiles towards washing machine parameters were visually and quantitatively assessed in dry state. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=behavior%20against%20washing%20machine%20parameters" title="behavior against washing machine parameters">behavior against washing machine parameters</a>, <a href="https://publications.waset.org/abstracts/search?q=performance%20evaluation%20of%20textiles" title=" performance evaluation of textiles"> performance evaluation of textiles</a>, <a href="https://publications.waset.org/abstracts/search?q=statistical%20analysis" title=" statistical analysis"> statistical analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=commercial%20and%20test%20textiles" title=" commercial and test textiles"> commercial and test textiles</a> </p> <a href="https://publications.waset.org/abstracts/43877/modelling-the-behavior-of-commercial-and-test-textiles-against-laundering-process-by-statistical-assessment-of-their-performance" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43877.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">359</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8934</span> Online Compressor Washing for Gas Turbine Power Output</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Enyia%20James%20Diwa">Enyia James Diwa</a>, <a href="https://publications.waset.org/abstracts/search?q=Isaiah%20Thank-God%20Ebi"> Isaiah Thank-God Ebi</a>, <a href="https://publications.waset.org/abstracts/search?q=Dodeye%20Ina%20Igbong"> Dodeye Ina Igbong</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The privatization of utilities has brought about very strong competition in industries such as petrochemical and gas distribution among others, considering the continuous increase in cost of fuel. This has brought about the intense reason for gas turbine owners and operators to reduce and control performance degradation of the engine in other to minimize cost. The most common and very crucial problem of the gas turbine is the fouling of compressor, which is mostly caused by a reduction in flow capacity, compressor efficiency, and pressure ratio, this, in turn, lead to the engine compressor re-matching and output power and thermal efficiency reduction. The content of this paper encompasses a detailed presentation of the major causes, effects and control mechanism of fouling. The major emphasis is on compressor water washing to enable power augmentation. A modelled gas turbine similar to that of GE LM6000 is modelled for the current study, based on TURBOMATCH which is a Cranfield University software specifically made for gas turbine performance simulation and fouling detection. The compounded and intricate challenges of compressor online water washing of large output gas turbine are carried out. The treatment is applied to axial compressor used in the petrochemical and hydrocarbon industry. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gas%20turbine" title="gas turbine">gas turbine</a>, <a href="https://publications.waset.org/abstracts/search?q=fouling" title=" fouling"> fouling</a>, <a href="https://publications.waset.org/abstracts/search?q=degradation" title=" degradation"> degradation</a>, <a href="https://publications.waset.org/abstracts/search?q=compressor%20washing" title=" compressor washing"> compressor washing</a> </p> <a href="https://publications.waset.org/abstracts/44357/online-compressor-washing-for-gas-turbine-power-output" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/44357.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">348</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8933</span> Analysis of the Result for the Accelerated Life Cycle Test of the Motor for Washing Machine by Using Acceleration Factor</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Youn-Sung%20Kim">Youn-Sung Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Jin-Ho%20Jo"> Jin-Ho Jo</a>, <a href="https://publications.waset.org/abstracts/search?q=Mi-Sung%20Kim"> Mi-Sung Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Jae-Kun%20Lee"> Jae-Kun Lee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Accelerated life cycle test is applied to various products or components in order to reduce the time of life cycle test in industry.

Since the hand is in constant contact with fomites which have been proven to be mostly contaminated, building hand hygiene habits is essential for the prevention of infection. This research was conducted to assess the hand hygiene habits of Ghanaian youths in Accra. This study used a survey as a quantitative method of research. The findings of the study revealed that out of the 254 participants who fully answered the questionnaire, 22% had the habit of washing their hands after outings while only 51.6% had the habit of washing their hands after using the bathroom. However, about 60% of the participants said they sometimes ate with their hands while 28.9% had the habit of eating with the hand very often, a situation that put them at risk of infection from their hands since some participants had poor handwashing habits; prompting the need for continuous education on hand hygiene. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hand%20hygiene" title="hand hygiene">hand hygiene</a>, <a href="https://publications.waset.org/abstracts/search?q=hand%20hygiene%20habit" title=" hand hygiene habit"> hand hygiene habit</a>, <a href="https://publications.waset.org/abstracts/search?q=hand%20washing" title=" hand washing"> hand washing</a>, <a href="https://publications.waset.org/abstracts/search?q=hand%20sanitizer%20use" title=" hand sanitizer use"> hand sanitizer use</a> </p> <a href="https://publications.waset.org/abstracts/159334/hand-hygiene-habits-of-ghanaian-youths-in-accra" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/159334.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">107</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8931</span> Consumers Attitude toward the Latest Trends in Decreasing Energy Consumption of Washing Machine</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Farnaz%20Alborzi">Farnaz Alborzi</a>, <a href="https://publications.waset.org/abstracts/search?q=Angelika%20Schmitz"> Angelika Schmitz</a>, <a href="https://publications.waset.org/abstracts/search?q=Rainer%20Stamminger"> Rainer Stamminger</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Reducing water temperatures in the wash phase of a washing programme and increasing the overall cycle durations are the latest trends in decreasing energy consumption of washing programmes. Since the implementation of the new energy efficiency classes in 2010, manufacturers seem to apply the aforementioned washing strategy with lower temperatures combined with longer programme durations extensively to realise energy-savings needed to meet the requirements of the highest energy efficiency class possible. A semi-representative on-line survey in eleven European countries (Czech Republic, Finland, France, Germany, Hungary, Italy, Poland, Romania, Spain, Sweden and the United Kingdom) was conducted by Bonn University in 2015 to shed light on consumer opinion and behaviour regarding the effects of the lower washing temperature and longer cycle duration in laundry washing on consumers’ acceptance of the programme. The risk of the long wash cycle is that consumers might not use the energy efficient Standard programmes and will think of this option as inconvenient and therefore switch to shorter, but more energy consuming programmes. Furthermore, washing in a lower temperature may lead to the problem of cross-contamination. Washing behaviour of over 5,000 households was studied in this survey to provide support and guidance for manufacturers and policy designers. Qualified households were chosen following a predefined quota: -Involvement in laundry washing: substantial, -Distribution of gender: more than 50 % female , -Selected age groups: -20–39 years, -40–59 years, -60–74 years, -Household size: 1, 2, 3, 4 and more than 4 people. Furthermore, Eurostat data for each country were used to calculate the population distribution in the respective age class and household size as quotas for the consumer survey distribution in each country. Before starting the analyses, the validity of each dataset was controlled with the aid of control questions. After excluding the outlier data, the number of the panel diminished from 5,100 to 4,843. The primary outcome of the study is European consumers are willing to save water and energy in a laundry washing but reluctant to use long programme cycles since they don’t believe that the long cycles could be energy-saving. However, the results of our survey don’t confirm that there is a relation between frequency of using Standard cotton (Eco) or Energy-saving programmes and the duration of the programmes. It might be explained by the fact that the majority of washing programmes used by consumers do not take so long, perhaps consumers just choose some additional time reduction option when selecting those programmes and this finding might be changed if the Energy-saving programmes take longer. Therefore, it may be assumed that introducing the programme duration as a new measure on a revised energy label would strongly influence the consumer at the point of sale. Furthermore, results of the survey confirm that consumers are more willing to use lower temperature programmes in order to save energy than accepting longer programme cycles and majority of them accept deviation from the nominal temperature of the programme as long as the results are good. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=duration" title="duration">duration</a>, <a href="https://publications.waset.org/abstracts/search?q=energy-saving" title=" energy-saving"> energy-saving</a>, <a href="https://publications.waset.org/abstracts/search?q=standard%20programmes" title=" standard programmes"> standard programmes</a>, <a href="https://publications.waset.org/abstracts/search?q=washing%20temperature" title=" washing temperature"> washing temperature</a> </p> <a href="https://publications.waset.org/abstracts/48126/consumers-attitude-toward-the-latest-trends-in-decreasing-energy-consumption-of-washing-machine" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/48126.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">221</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8930</span> Surface Modification of Polyethylene Terephthalate Substrates via Direct Fluorination to Promote the Ag+ Ions Adsorption</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kohei%20Yamamoto">Kohei Yamamoto</a>, <a href="https://publications.waset.org/abstracts/search?q=Jae-Ho%20Kim"> Jae-Ho Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Susumu%20Yonezawa"> Susumu Yonezawa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The surface of polyethylene terephthalate (PET) was modified with fluorine gas at 25 ℃ and 100 Torr for one h. Moreover, the effect of ethanol washing on surface modification was investigated in this study. The surface roughness of the fluorinated and washed PET samples was approximately six times larger than that (0.6 nm) of the untreated thing. The results of Fourier transform infrared spectroscopy, and X-ray photoelectron spectroscopy showed that the bonds such as -C=O and -C-Hx derived from raw PET decreased and were converted into fluorinated bonds such as -CFx after surface fluorination. Even after washing with ethanol, the fluorinated bonds stably existed on the surface. These fluorinated bonds showed higher electronegativity according to the zeta potential results. The negative surface charges were increased by washing the ethanol, and it caused to increase in the number of polar groups such as -CHF- and -C-Fx. The fluorinated and washed surface of PET could promote the adsorption of Ag+ ions in AgNO₃ solution because of the increased surface roughness and the negatively charged surface. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ag%2B%20ions%20adsorption" title="Ag+ ions adsorption">Ag+ ions adsorption</a>, <a href="https://publications.waset.org/abstracts/search?q=polyethylene%20terephthalate" title=" polyethylene terephthalate"> polyethylene terephthalate</a>, <a href="https://publications.waset.org/abstracts/search?q=surface%20fluorination" title=" surface fluorination"> surface fluorination</a>, <a href="https://publications.waset.org/abstracts/search?q=zeta%20potential" title=" zeta potential"> zeta potential</a> </p> <a href="https://publications.waset.org/abstracts/152869/surface-modification-of-polyethylene-terephthalate-substrates-via-direct-fluorination-to-promote-the-ag-ions-adsorption" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/152869.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">121</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8929</span> A Study on the Accelerated Life Cycle Test Method of the Motor for Home Appliances by Using Acceleration Factor </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Youn-Sung%20Kim">Youn-Sung Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Mi-Sung%20Kim"> Mi-Sung Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Jae-Kun%20Lee"> Jae-Kun Lee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper deals with the accelerated life cycle test method of the motor for home appliances that demand high reliability.

It is activated by the drum shaft which is attached to an electric motor and subjected to dynamic loading. Being one of the critical components, failures of the drum require costly repairs of dynamic components. In this study, tolerance bands between the drum shaft and its two bearings were examined to develop a relationship between the fatigue life of the shaft and the interaction tolerances. Optimization of tolerance bands was completed in consideration of the fatigue life of the shaft as the cost function. The following methodology is followed: multibody dynamic model of a washing machine was constructed and used to calculate dynamic loading on the components. Then, these forces were used in finite element analyses to calculate the stress field in critical components which was used for fatigue life predictions. The factors affecting the fatigue life were examined to find optimum tolerance grade for a given test condition. Numerical results were verified by experimental observations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fatigue%20life" title="fatigue life">fatigue life</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20analysis" title=" finite element analysis"> finite element analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=tolerance%20analysis" title=" tolerance analysis"> tolerance analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=optimization" title=" optimization"> optimization</a> </p> <a href="https://publications.waset.org/abstracts/90903/optimization-of-tolerance-grades-of-a-bearing-and-shaft-assembly-in-a-washing-machine-with-regard-to-fatigue-life" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/90903.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">157</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8927</span> Evaluation of Washing Performance of Household Wastewater Purified by Advanced Oxidation Process</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nazl%C4%B1%20%C3%87etinda%C4%9F">Nazlı Çetindağ</a>, <a href="https://publications.waset.org/abstracts/search?q=Pelin%20Y%C4%B1lmaz%20%C3%87etiner"> Pelin Yılmaz Çetiner</a>, <a href="https://publications.waset.org/abstracts/search?q=Metin%20Mert%20%C4%B0lg%C3%BCn"> Metin Mert İlgün</a>, <a href="https://publications.waset.org/abstracts/search?q=Emine%20Birci"> Emine Birci</a>, <a href="https://publications.waset.org/abstracts/search?q=Gizemnur%20Y%C4%B1ld%C4%B1z%20Uysal"> Gizemnur Yıldız Uysal</a>, <a href="https://publications.waset.org/abstracts/search?q=%C3%96zcan%20Hatipo%C4%9Flu"> Özcan Hatipoğlu</a>, <a href="https://publications.waset.org/abstracts/search?q=Ehsan%20Tuzcuo%C4%9Flu"> Ehsan Tuzcuoğlu</a>, <a href="https://publications.waset.org/abstracts/search?q=G%C3%B6khan%20S%C4%B1r"> Gökhan Sır</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Stressing the importance of water conservation, emphasizing the need for efficient management of household water, and underlining the significance of alternative solutions are important. In this context, advanced solutions based on technologies such as the advanced oxidation process have emerged as promising methods for treating household wastewater. Evaluating household water usage holds critical importance for the sustainability of water resources. Researchers and experts are examining various technological approaches to effectively treat and reclaim water for reuse. In this framework, the advanced oxidation process has proven to be an effective method for the removal of various organic and inorganic pollutants in the treatment of household wastewater. In this study, performance will be evaluated by comparing it with the reference case. This international criterion simulates the washing of home textile products, determining various performance parameters. The specially designed stain strips, including sebum, carbon black, blood, cocoa, and red wine, used in experiments, represent various household stains. These stain types were carefully selected to represent challenging stain scenarios, ensuring a realistic assessment of washing performance. Experiments conducted under different temperatures and program conditions successfully demonstrate the practical applicability of the advanced oxidation process for treating household wastewater. It is important to note that both adherence to standards and the use of real-life stain types contribute to the broad applicability of the findings. In conclusion, this study strongly supports the effectiveness of treating household wastewater with the advanced oxidation process in terms of washing performance under both standard and practical application conditions. The study underlines the importance of alternative solutions for sustainable water resource management and highlights the potential of the advanced oxidation process in the treatment of household water, contributing significantly to optimizing water usage and developing sustainable water management solutions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=advanced%20oxidation%20process" title="advanced oxidation process">advanced oxidation process</a>, <a href="https://publications.waset.org/abstracts/search?q=household%20water%20usage" title=" household water usage"> household water usage</a>, <a href="https://publications.waset.org/abstracts/search?q=household%20appliance%20waste%20water" title=" household appliance waste water"> household appliance waste water</a>, <a href="https://publications.waset.org/abstracts/search?q=modelling" title=" modelling"> modelling</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20reuse" title=" water reuse"> water reuse</a> </p> <a href="https://publications.waset.org/abstracts/179272/evaluation-of-washing-performance-of-household-wastewater-purified-by-advanced-oxidation-process" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/179272.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">64</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8926</span> Ozone Treatment in Textile Industry</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Umut%20%C3%87%C4%B1nar">Umut Çınar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The fact that ozone gas has color bleaching properties has made the use of ozone gas widespread in the textile sector as well as in many other sectors. Ozone gas, which is a strong oxidative agent on the fabric, causes the paint on the fabric to wear off and lighten its color with an aged appearance. Within the scope of this thesis, parameters affecting the bleaching properties of ozone gas on reactive dyed knitted fabric, which is rare in the literature, were investigated. Ozone concentration, time, and pH values were analyzed with the Box Behnken experimental design method, and optimum conditions were determined. After the experiments, wear and opacity values were measured with the help of a spectrophotometer. With the help of the Design Expert program, the graphics related to the data were prepared and interpreted with Box Behnken and ANOVA. These experiments on reactive dyed knitted fabric were tested on these parameters, and the spectrophotometric values of the fabric and optimum parameters in abrasion and opacity were revealed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ozone" title="ozone">ozone</a>, <a href="https://publications.waset.org/abstracts/search?q=reactive%20dye" title=" reactive dye"> reactive dye</a>, <a href="https://publications.waset.org/abstracts/search?q=bleaching" title=" bleaching"> bleaching</a>, <a href="https://publications.waset.org/abstracts/search?q=textile" title=" textile"> textile</a>, <a href="https://publications.waset.org/abstracts/search?q=garment%20wash" title=" garment wash"> garment wash</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainability" title=" sustainability"> sustainability</a>, <a href="https://publications.waset.org/abstracts/search?q=washing" title=" washing"> washing</a>, <a href="https://publications.waset.org/abstracts/search?q=Box%E2%80%93Behnken" title=" Box–Behnken"> Box–Behnken</a>, <a href="https://publications.waset.org/abstracts/search?q=experimental%20design" title=" experimental design"> experimental design</a> </p> <a href="https://publications.waset.org/abstracts/168203/ozone-treatment-in-textile-industry" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/168203.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">70</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8925</span> Treatment of Onshore Petroleum Drill Cuttings via Soil Washing Process: Characterization and Optimal Conditions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=T.%20Poyai">T.

Drilling always requires the use of drilling mud for lubricating the drill bit and controlling the subsurface pressure. As drilling proceeds, a considerable amount of cuttings or rock fragments is generated. In general, water or Water Based Mud (WBM) serves as drilling fluid for the top hole section. The cuttings generated from this section is non-hazardous and normally applied as fill materials. On the other hand, drilling the bottom hole to reservoir section uses Synthetic Based Mud (SBM) of which synthetic oils are composed. The bottom-hole cuttings, SBM cuttings, is regarded as a hazardous waste, in accordance with the government regulations, due to the presence of hydrocarbons. Currently, the SBM cuttings are disposed of as an alternative fuel and raw material in cement kiln. Instead of burning, this work aims to propose an alternative for drill cuttings management under two ultimate goals: (1) reduction of hazardous waste volume; and (2) making use of the cleaned cuttings. Soil washing was selected as the major treatment process. The physiochemical properties of drill cuttings were analyzed, such as size fraction, pH, moisture content, and hydrocarbons. The particle size of cuttings was analyzed via light scattering method. Oil present in cuttings was quantified in terms of total petroleum hydrocarbon (TPH) through gas chromatography equipped with flame ionization detector (GC-FID). Other components were measured by the standard methods for soil analysis. Effects of different washing agents, liquid-to-solid (L/S) ratio, washing time, mixing speed, rinse-to-solid (R/S) ratio, and rinsing time were also evaluated. It was found that drill cuttings held the electrical conductivity of 3.84 dS/m, pH of 9.1, and moisture content of 7.5%. The TPH in cuttings existed in the diesel range with the concentration ranging from 20,000 to 30,000 mg/kg dry cuttings. A majority of cuttings particles held a mean diameter of 50 µm, which represented silt fraction. The results also suggested that a green solvent was considered most promising for cuttings treatment regarding occupational health, safety, and environmental benefits. The optimal washing conditions were obtained at L/S of 5, washing time of 15 min, mixing speed of 60 rpm, R/S of 10, and rinsing time of 1 min. After washing process, three fractions including clean cuttings, spent solvent, and wastewater were considered and provided with recommendations. The residual TPH less than 5,000 mg/kg was detected in clean cuttings. The treated cuttings can be then used for various purposes. The spent solvent held the calorific value of higher than 3,000 cal/g, which can be used as an alternative fuel. Otherwise, the recovery of the used solvent can be conducted using distillation or chromatography techniques. Finally, the generated wastewater can be combined with the produced water and simultaneously managed by re-injection into the reservoir. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=drill%20cuttings" title="drill cuttings">drill cuttings</a>, <a href="https://publications.waset.org/abstracts/search?q=green%20solvent" title=" green solvent"> green solvent</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20washing" title=" soil washing"> soil washing</a>, <a href="https://publications.waset.org/abstracts/search?q=total%20petroleum%20hydrocarbon%20%28TPH%29" title=" total petroleum hydrocarbon (TPH)"> total petroleum hydrocarbon (TPH)</a> </p> <a href="https://publications.waset.org/abstracts/81709/treatment-of-onshore-petroleum-drill-cuttings-via-soil-washing-process-characterization-and-optimal-conditions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/81709.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">153</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8924</span> Opportunities Forensics Biology in the Study of Sperm Traces after Washing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Saule%20Musabekova">Saule Musabekova</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Achievements of modern science, especially genetics, led to a sharp intensification of the process of proof. Footprints, subjected to destruction-related cause-effect relationships, are sources of evidentiary information on the circumstances it was committed and the persons committed it. Currently, with the overall growth in the number of crimes against sexual inviolability or sexual freedom, and increased the proportion of the crimes where to destroy the traces of the crime perpetrators different detergents are used. A characteristic feature of modern synthetic detergents is the presence of biological additives - enzymes that break down and gradually destroy stains of protein origin. To study the nature of the influence of modern washing powders semen stains were put kinds of fabrics and prepared in advance stained sperm of men of different groups according to ABO system. For research washing machines of known manufacturers of household appliances have been used with different production characteristics, in which the test was performed and the washing of various kinds of fabrics with semen stains. After washing the tissue with spots were tested for the presence of semen stains visually preserved, establishing in them surviving sperm or their elements, we studied the possibilities of the group diagnostics on the system ABO or molecular-genetic identification. The subsequent study of these spots by morphological method showed that 100% detection of morphological sperm cells - sperm is not possible. As a result, in 30% of further studies of these traces gave weakly positive results are obtained with an immunoassay test PSA SEMIQUANT. It is noted that the percentage of positive results obtained in the study of semen traces disposed on natural fiber fabrics is higher than sperm traces disposed on synthetic fabrics. Study traces of semen, confirmed by PSA - test 3% possible to establish a genetic profile of the person and obtain any positive findings of the molecular genetic examination. In other cases, it was not a sufficient amount of material for DNA identification. Results of research and the practical expert study found, in most cases, the conclusions of the identification of sperm traces do not seem possible. This a consequence of exposure to semen traces on the material evidence of biological additives contained in modern detergents and further the influence of other effective methods. Resulting in DNA has undergone irreversible changes (degradation) under the influence of external human factors. Using molecular genetic methods can partially solve the problems arising in the study of unlaundered physical evidence for the disclosure and investigation of crimes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=study%20of%20sperm" title="study of sperm">study of sperm</a>, <a href="https://publications.waset.org/abstracts/search?q=modern%20detergents" title=" modern detergents"> modern detergents</a>, <a href="https://publications.waset.org/abstracts/search?q=washing%20powders" title=" washing powders"> washing powders</a>, <a href="https://publications.waset.org/abstracts/search?q=forensic%20medicine" title=" forensic medicine"> forensic medicine</a> </p> <a href="https://publications.waset.org/abstracts/51946/opportunities-forensics-biology-in-the-study-of-sperm-traces-after-washing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/51946.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">298</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8923</span> Fabrication of Eco-Friendly Pigment Printed Textiles by Reducing Formaldehyde Content</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sidra%20Saleemi">Sidra Saleemi</a>, <a href="https://publications.waset.org/abstracts/search?q=Raja%20Fahad%20Qureshi"> Raja Fahad Qureshi</a>, <a href="https://publications.waset.org/abstracts/search?q=Farooq%20Ahmed"> Farooq Ahmed</a>, <a href="https://publications.waset.org/abstracts/search?q=Rabia%20Almas"> Rabia Almas</a>, <a href="https://publications.waset.org/abstracts/search?q=Tahir%20Jameel"> Tahir Jameel</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This research aimed to decrease formaldehyde content in substrates printed by pigments using different fixation temperature and concentration of urea in order to produce eco-friendly textiles.

Sludge waste of paper industries as toxic and hazardous material from specific source contains Pb, Zn, and Cu metal from waste soluble ink. An alternative and eco-friendly method of remediation technology is the use of biosurfactants and biosurfactant-producing microorganisms. Soil washing is among the methods available to remove heavy metal from sediments. The purpose of this research is to study effectiveness of biosurfactant with concentration = CMC for the removal of heavy metals, lead, zinc and copper in batch washing test under four different biosurfactant production by microbial origin. Pseudomonas putida T1(8), Bacillus subtilis 3K, Acinetobacter sp, and Actinobacillus sp was grown on mineral salt medium that had been already added with 2% concentration of molasses that it is a low cost application. The samples were kept in a shaker 120 rpm at room temperature for 3 days. Supernatants and sediments of sludge were separated by using a centrifuge and samples from supernatants were measured by atomic absorption spectrophotometer. The highest removal of Pb was up to 14,04% by Acinetobacter sp. Biosurfactant of Pseudomonas putida T1(8) have the highest removal for Zn and Cu up to 6,5% and 2,01% respectively. Biosurfactants have a role for removal process of the metals, including wetting, contact of biosurfactant to the surface of the sediments and detachment of the metals from the sediment. Biosurfactant has proven its ability as a washing agent in heavy metals removal from sediments, but more research is needed to optimize the process of removal heavy metals. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biosurfactant" title="biosurfactant">biosurfactant</a>, <a href="https://publications.waset.org/abstracts/search?q=removal%20of%20heavy%20metals" title=" removal of heavy metals"> removal of heavy metals</a>, <a href="https://publications.waset.org/abstracts/search?q=sludge%20waste" title=" sludge waste"> sludge waste</a>, <a href="https://publications.waset.org/abstracts/search?q=paper%20industries" title=" paper industries"> paper industries</a> </p> <a href="https://publications.waset.org/abstracts/15107/removal-of-heavy-metals-pb-zn-and-cu-from-sludge-waste-of-paper-industries-using-biosurfactant" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/15107.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">330</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8921</span> Economic and Ecological Implications in Agricultural Production Within the Strong and Weak Sustainability Framework</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mauricio%20Quintero%20Angel">Mauricio Quintero Angel</a>, <a href="https://publications.waset.org/abstracts/search?q=Andr%C3%A9s%20A.%20Duque%20Nivia"> Andrés A.

In this case, a company demand the oil palm as the active element for washing and through its trademark aims to supply 10% of the Colombian market of washing powders. Under each approach the economic and ecological implications of the palm oil production and especially the implications for crop management are described. The crop production under the weak sustainability implies plantations, intensive use of agrochemicals and the inclusion of new areas of cultivation as the market grows. Under the strong sustainability the production system is limited by the productive vocation of the ecosystem, so that new approaches and creativity for making viable the nature conservancy and the business development are require. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=agriculture" title="agriculture">agriculture</a>, <a href="https://publications.waset.org/abstracts/search?q=environmental%20impacts" title=" environmental impacts"> environmental impacts</a>, <a href="https://publications.waset.org/abstracts/search?q=oil%20palm" title=" oil palm"> oil palm</a>, <a href="https://publications.waset.org/abstracts/search?q=strong%20sustainability" title=" strong sustainability"> strong sustainability</a>, <a href="https://publications.waset.org/abstracts/search?q=weak%20sustainability" title=" weak sustainability "> weak sustainability </a> </p> <a href="https://publications.waset.org/abstracts/29377/economic-and-ecological-implications-in-agricultural-production-within-the-strong-and-weak-sustainability-framework" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29377.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">431</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8920</span> Cotton Fabrics Functionalized with Green and Commercial Ag Nanoparticles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Laura%20Gonzalez">Laura Gonzalez</a>, <a href="https://publications.waset.org/abstracts/search?q=Santiago%20Benavides"> Santiago Benavides</a>, <a href="https://publications.waset.org/abstracts/search?q=Martha%20Elena%20Londono"> Martha Elena Londono</a>, <a href="https://publications.waset.org/abstracts/search?q=Ana%20Elisa%20Casas"> Ana Elisa Casas</a>, <a href="https://publications.waset.org/abstracts/search?q=Adriana%20Restrepo-Osorio"> Adriana Restrepo-Osorio</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Cotton products are sensitive to microorganisms due to its ability to retain moisture, which might cause change into the coloration, mechanical properties reduction or foul odor generation; consequently, this represents risks to the health of users. Nowadays, have been carried out researches to give antibacterial properties to textiles using different strategies, which included the use of silver nanoparticles (AgNPs). The antibacterial behavior can be affected by laundering process reducing its effectiveness. In the other way, the environmental impact generated for the synthetic antibacterial agents has motivated to seek new and more ecological ways for produce AgNPs. The aims of this work are to determine the antibacterial activity of cotton fabric functionalized with green (G) and commercial (C) AgNPs after twenty washing cycles, also to evaluate morphological and color changes. A plain weave cotton fabric suitable for dyeing and two AgNPs solutions were use. C a commercial product and G produced using an ecological method, both solutions with 0.5 mM concentration were impregnated on cotton fabric without stabilizer, at a liquor to fabric ratio of 1:20 in constant agitation during 30min and then dried at 70 °C by 10 min. After that the samples were subjected to twenty washing cycles using phosphate-free detergent simulated on agitated flask at 150 rpm, then were centrifuged and dried on a tumble. The samples were characterized using Kirby-Bauer test determine antibacterial activity against E. coli y S. aureus microorganisms, the results were registered by photographs establishing the inhibition halo before and after the washing cycles, the tests were conducted in triplicate. Scanning electron microscope (SEM) was used to observe the morphologies of cotton fabric and treated samples. The color changes of cotton fabrics in relation to the untreated samples were obtained by spectrophotometer analysis. The images, reveals the presence of inhibition halo in the samples treated with C and G AgNPs solutions, even after twenty washing cycles, which indicated a good antibacterial activity and washing durability, with a tendency to better results against to S. aureus bacteria. The presence of AgNPs on the surface of cotton fiber and morphological changes were observed through SEM, after and before washing cycles. The own color of the cotton fiber has been significantly altered with both antibacterial solutions. According to the colorimetric results, the samples treated with C lead to yellowing while the samples modified with G to red yellowing Cotton fabrics treated AgNPs C and G from 0.5 mM solutions exhibited excellent antimicrobial activity against E. coli and S. aureus with good laundering durability effects. The surface of the cotton fibers was modified with the presence of AgNPs C and G due to the presence of NPs and its agglomerates. There are significant changes in the natural color of cotton fabric due to deposition of AgNPs C and G which were maintained after laundering process. <p class="card-text"><strong>Keywords:</strong>
