A comparison of water quality with the values adopted internationally was accomplished to demonstrate the suitability for human and irrigation use. The experimental results showed that the values of pH and EC of the studied for water samples did not exceed the allowed range for drinking water. While TDS, TH, (Mg-H) and chloride values have exceeded the acceptable limit for drinking water internationally, calcium (Ca-H) results have shown a decrease in values of all samples except the first sample which record a marginal increase. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=physiochemical%20properties" title="physiochemical properties">physiochemical properties</a>, <a href="https://publications.waset.org/abstracts/search?q=Ain%20Kaam%20lagoon" title=" Ain Kaam lagoon"> Ain Kaam lagoon</a>, <a href="https://publications.waset.org/abstracts/search?q=Zliten" title=" Zliten"> Zliten</a>, <a href="https://publications.waset.org/abstracts/search?q=Libya" title=" Libya"> Libya</a> </p> <a href="https://publications.waset.org/abstracts/41833/study-of-some-physiochemical-properties-of-ain-kaam-water-lagoon-and-assessing-their-suitability-for-human-use-and-irrigation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41833.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">9004</span> Effect of Golden Oyster Mushroom (Pleurotus citrinopileatus) Powder on Physiochemical, Antioxidative, and Sensory Properties of Noodles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Giap%20Pham%20Ngoc%20Tram">Giap Pham Ngoc Tram</a>, <a href="https://publications.waset.org/abstracts/search?q=Tran%20Hong%20Quan"> Tran Hong Quan</a>, <a href="https://publications.waset.org/abstracts/search?q=Tran%20Tieu%20Yen"> Tran Tieu Yen</a>, <a href="https://publications.waset.org/abstracts/search?q=Nguyen%20Phung%20Tien"> Nguyen Phung Tien</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The use of natural ingredients to enhance the nutritional and sensory properties of food products has gained significant interest in recent years. This study focuses on the effect of Golden oyster mushroom powder (GOMP) on the physiochemical, antioxidative, and sensory properties of noodles. The aim of this study is to investigate the influence of GOMP on the nutritional, antioxidant, and sensory properties of noodles. The study determined the color, moisture, total ash, protein, total phenolic, flavonoid contents, water activity, and antioxidant activity of GOMP and noodles. The incorporation of GOMP at levels of 5-15% increased the ash, protein, flavonoid, and total phenolic contents of the noodles. It also enhanced their antioxidant activities, as evidenced by improved DPPH radical scavenging activity and metal chelating activity. However, the incorporation of GOMP resulted in a decrease in the L* and b* values of the noodles. Furthermore, the GOMP-enriched noodles exhibited a lower cutting force compared to the control. This study highlights the potential of GOMP as a nutritional and antioxidant ingredient in noodle preparation. It adds to the existing literature by providing evidence of the positive effects of GOMP on the nutritional and functional properties of noodles. The researchers collected data on the physiochemical properties, nutritional contents, and antioxidant activities of GOMP and noodles. Statistical analysis was then performed to assess the differences between the control and GOMP-enriched noodles. The results of this study demonstrate that the inclusion of GOMP at the amount of 5-15% can increase the nutritional and antioxidant properties of noodles without significantly impacting sensory attributes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=oyster%20mushroom" title="oyster mushroom">oyster mushroom</a>, <a href="https://publications.waset.org/abstracts/search?q=noodles" title=" noodles"> noodles</a>, <a href="https://publications.waset.org/abstracts/search?q=antioxidant%20activity" title=" antioxidant activity"> antioxidant activity</a>, <a href="https://publications.waset.org/abstracts/search?q=phytochemical" title=" phytochemical"> phytochemical</a>, <a href="https://publications.waset.org/abstracts/search?q=sensory%20property" title=" sensory property"> sensory property</a> </p> <a href="https://publications.waset.org/abstracts/178292/effect-of-golden-oyster-mushroom-pleurotus-citrinopileatus-powder-on-physiochemical-antioxidative-and-sensory-properties-of-noodles" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/178292.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">65</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">9003</span> Some Characteristics and Identification of Fungi Contaminated by Alkomos Cement Factory</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdulmajeed%20Bashir%20Mlitan">Abdulmajeed Bashir Mlitan</a>, <a href="https://publications.waset.org/abstracts/search?q=Ethan%20Hack"> Ethan Hack</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Soil samples were collected from and around Alkomos cement factory, Alkomos town, Libya. Soil physiochemical properties were determined. In addition, olive leaves were scanned for their fungal content. This work can conclude that the results obtained for the examined physiochemical characteristics of soil in the area studied prove that cement dust from the Alkomos cement factory in Libya has had a significant impact on the soil. The affected soil properties are pH and total calcium content. These characteristics were found to be higher than those in similar soils from the same area. The increment of soil pH in the same area may be a result of precipitation of cement dust over the years. Different responses were found in each season and each site. For instance, the dominance of fungi of soil and leaves was lowest at 100 m from the factory and the evenness and diversity increased at this site compared to the control area and 250 m from the factory. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pollution" title="pollution">pollution</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20microbial" title=" soil microbial"> soil microbial</a>, <a href="https://publications.waset.org/abstracts/search?q=alkomos" title=" alkomos"> alkomos</a>, <a href="https://publications.waset.org/abstracts/search?q=Libya" title=" Libya"> Libya</a> </p> <a href="https://publications.waset.org/abstracts/19051/some-characteristics-and-identification-of-fungi-contaminated-by-alkomos-cement-factory" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19051.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">615</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">9002</span> Optimization of Black Grass Jelly Formulation to Reduce Leaching and Increase Floating Rate</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20M.%20Nor">M.

Fadhlina</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Black grass jelly (BGJ) is a popular black jelly used in preparing various drinks and desserts. Food industries often use preservatives to maintain the physicochemical properties of foods, such as color and texture. These preservatives (e.g., phosphoric acid) are linked with deleterious health effects such as kidney disease. Using gelling agents, carrageenan, and gelatin to make BGJ could improve its physiochemical and textural properties. This study was designed to optimize BGJ-selected physicochemical and textural properties using carrageenan and gelatin. Various black grass jelly formulations (BGJF) were designed using an I-optimal mixture design in Design Expert® software. Data from commercial BGJ were used as a reference during the optimization process. The combination of carrageenan and gelatin added to the formulations was up to 14.38g (~5%), respectively. The results showed that adding 2.5g carrageenan and 2.5g gelatin at approximately 5g (~5%) effectively maintained most of the physiochemical properties with an overall desirability function of 0.81. This formulation was selected as the optimum black grass jelly formulation (OBGJF). The leaching properties and floating duration were measured on the OBGJF and commercial grass jelly for 20 min and 40 min, respectively. The results indicated that OBGJF showed significantly (p<0.0001) lower leaching rate and floating time (p<0.05). Hence, further optimization is needed to increase the floating duration of carrageenan and gelatin-based BGJ. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cincau" title="cincau">cincau</a>, <a href="https://publications.waset.org/abstracts/search?q=Mesona%20chinensis" title=" Mesona chinensis"> Mesona chinensis</a>, <a href="https://publications.waset.org/abstracts/search?q=black%20grass%20jelly" title=" black grass jelly"> black grass jelly</a>, <a href="https://publications.waset.org/abstracts/search?q=carrageenan" title=" carrageenan"> carrageenan</a>, <a href="https://publications.waset.org/abstracts/search?q=gelatin" title=" gelatin"> gelatin</a> </p> <a href="https://publications.waset.org/abstracts/164171/optimization-of-black-grass-jelly-formulation-to-reduce-leaching-and-increase-floating-rate" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/164171.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">82</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">9001</span> Preparation and Functional Properties of Synbiotic Yogurt Fermented with Lactobacillus brevis PML1 Derived from a Fermented Cereal-Dairy Product</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Farideh%20Tabatabei-Yazdi">Farideh Tabatabei-Yazdi</a>, <a href="https://publications.waset.org/abstracts/search?q=Fereshteh%20Falah"> Fereshteh Falah</a>, <a href="https://publications.waset.org/abstracts/search?q=Alireza%20Vasiee"> Alireza Vasiee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nowadays, production of functional foods has become very essential. Inulin is one of the most functional hydrocolloid compounds used in such products. In the present study, the production of a synbiotic yogurt containing 1, 2.5, and 5% (w/v) inulin has been investigated. The yogurt was fermented with Lactobacillus brevis PML1 derived from Tarkhineh, an Iranian cereal-dairy fermented food. Furthermore, the physicochemical properties, antioxidant activity, sensory attributes, and microbial viability properties were investigated on the 0th, 7th, and 14th days of storage after fermentation. The viable cells of L. brevis PML1 reached 108 CFU/g, and the product resisted to simulated digestive juices. Moreover, the synbiotic yogurt impressively increased the production of antimicrobial compounds and had the most profound antimicrobial effect on S. typhimurium. The physiochemical properties were in the normal range, and the fat content of the synbiotic yogurt was reduced remarkably. The antioxidant capacity of the fermented yogurt was significantly increased (p<0:05), which was equal to those of DPPH (69:18±1:00%) and BHA (89:16±2:00%). The viability of L. brevis PML1 was increased during storage. Sensory analysis showed that there were significant differences in terms of the impressive parameters between the samples and the control (p<0:05). Addition of 2.5% inulin not only improved the physical properties but also retained the viability of the probiotic after 14 days of storage, in addition to the viability of L. brevis with a viability count above 6 log CFU/g in the yogurt. Therefore, a novel synbiotic product containing L. brevis PML1, which can exert the desired properties, can be used as a suitable carrier for the delivery of the probiotic strain, exerting its beneficial health effects. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=functional%20food" title="functional food">functional food</a>, <a href="https://publications.waset.org/abstracts/search?q=lactobacillus%20brevis" title=" lactobacillus brevis"> lactobacillus brevis</a>, <a href="https://publications.waset.org/abstracts/search?q=symbiotic%20yogurt" title=" symbiotic yogurt"> symbiotic yogurt</a>, <a href="https://publications.waset.org/abstracts/search?q=physiochemical%20properties" title=" physiochemical properties"> physiochemical properties</a> </p> <a href="https://publications.waset.org/abstracts/150723/preparation-and-functional-properties-of-synbiotic-yogurt-fermented-with-lactobacillus-brevis-pml1-derived-from-a-fermented-cereal-dairy-product" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/150723.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">91</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">9000</span> An Artificial Intelligence Supported QUAL2K Model for the Simulation of Various Physiochemical Parameters of Water</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mehvish%20Bilal">Mehvish Bilal</a>, <a href="https://publications.waset.org/abstracts/search?q=Navneet%20Singh"> Navneet Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=Jasir%20Mushtaq"> Jasir Mushtaq</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Water pollution puts people's health at risk, and it can also impact the ecology. For practitioners of integrated water resources management (IWRM), water quality modelling may be useful for informing decisions about pollution control (such as discharge permitting) or demand management (such as abstraction permitting). To comprehend the current pollutant load, movement of effective load movement of contaminants generates effective relation between pollutants, mathematical simulation, source, and water quality is regarded as one of the best estimating tools. The current study involves the Qual2k model, which includes manual simulation of the various physiochemical characteristics of water. To this end, various sensors could be installed for the automatic simulation of various physiochemical characteristics of water. An artificial intelligence model has been proposed for the automatic simulation of water quality parameters. Models of water quality have become an effective tool for identifying worldwide water contamination, as well as the ultimate fate and behavior of contaminants in the water environment. Water quality model research is primarily conducted in Europe and other industrialized countries in the first world, where theoretical underpinnings and practical research are prioritized. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=artificial%20intelligence" title="artificial intelligence">artificial intelligence</a>, <a href="https://publications.waset.org/abstracts/search?q=QUAL2K" title=" QUAL2K"> QUAL2K</a>, <a href="https://publications.waset.org/abstracts/search?q=simulation" title=" simulation"> simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=physiochemical%20parameters" title=" physiochemical parameters"> physiochemical parameters</a> </p> <a href="https://publications.waset.org/abstracts/158566/an-artificial-intelligence-supported-qual2k-model-for-the-simulation-of-various-physiochemical-parameters-of-water" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/158566.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">105</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">8999</span> Screening of Metal Chloride Anion-based Ionic Liquids for Direct Conversion of Hydrogen Sulfide by COSMO-RS</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Syahir%20Aminuddin">Muhammad Syahir Aminuddin</a>, <a href="https://publications.waset.org/abstracts/search?q=Zakaria%20Man"> Zakaria Man</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamad%20Azmi%20Bustam%20Khalil"> Mohamad Azmi Bustam Khalil </a> </p> <p class="card-text"><strong>Abstract:</strong></p> In order to identify the best possible reaction media for performing H₂S conversion, a total number of 300 different ILs from a combination of 20 cations and 15 anions were screened via COSMO-RS model simulations.

It was ascertained that the human functions and activities were dependent on the continuous and availability of good drinking water. Six water samples were collected at six different boreholes from various outlets and homes in Ikorodu North local council development area. Lagos state Nigeria. Analysis was carried out to determine the purity of water for domestic use. Physicochemical properties evaluation was adapted using standard chemical methods. A number of parameters such as PH, turbidity, conductivity, total dissolved solids, color, chloride, sulphate, nitrate, hardness were determined. Heavy metals such as Zn, Mg, Fe, Pb, Hg, and Mn as well as total coliform counts were observed. The resulted values of each parameter were justified with World Health Organization (WHO) and Lagos state water regulatory commission LSWRC standard values for quantitative comparison. The result reveals that all the water had pH value well below the WHO maximum permissible level for potable water. Other physicochemical parameters were within the safe limit of WHO standard showing the portability nature of the water. It can be concluded that though the water is potable, there should be a kind of treatment of the water before consumption to prevent outbreak of diseases. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=drinking%20water" title="drinking water">drinking water</a>, <a href="https://publications.waset.org/abstracts/search?q=physiology" title=" physiology"> physiology</a>, <a href="https://publications.waset.org/abstracts/search?q=boreholes" title=" boreholes"> boreholes</a>, <a href="https://publications.waset.org/abstracts/search?q=heavy%20metals" title=" heavy metals"> heavy metals</a>, <a href="https://publications.waset.org/abstracts/search?q=domestic" title=" domestic"> domestic</a> </p> <a href="https://publications.waset.org/abstracts/83128/physiochemical-parameters-assessment-and-evaluation-of-the-quality-of-drinking-water-in-some-parts-of-lagos-state" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/83128.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">220</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">8997</span> Electrical Geophysical and Physiochemical Assessment of the Impact of Environmental Pollution on the Groundwater Potential of a Waste Land fill at Tudun Murtala in Nassarawa Local Government Area, Kano State, Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abubakar%20Maitama%20Yusuf%20Hotoro">Abubakar Maitama Yusuf Hotoro</a>, <a href="https://publications.waset.org/abstracts/search?q=Olokpo%20Israel%20Olofu"> Olokpo Israel Olofu</a>, <a href="https://publications.waset.org/abstracts/search?q=Yusuf%20U.%20Tarauni"> Yusuf U.

The study area is located between latitude 12.023678N and longitude 8.573676 E. Geophysical data were collected at maximum length of 140m along twelve profiles using ABEM Terrameter SAS 1000. Results from the Geophysical analysis showed that the profiles were underlain by three lithological layers; the top layer consisting of Loamy and Sand soils, alluvium, granite, shale and sandstone. The second and third layers were predominantly made of weathered and fractured basements respectively. The potential groundwater water bearing zones of the study area occurred at VES2, VES4, VES5, VES6 and VES7. The thicknesses of the sounding points were found to be 20.8m at VES2; 25.2m at VES4; 13.2m at VES5; 50.8m at VES6 and 13.3m at VES7. The corresponding depths for the sounding points were 20.8m at VES2; 27.9m at VES4; 26.7m at VES5; 51.6m at VES6 and 24.9m at VES7 respectively. The Physiochemical study of selected groundwater samples assessed parameters such as the Electrical Conductivity, EC (288dS/m to 1365dS/m), TDS (170.8mg/L to 820mg/L) Pb (0.546mg/l to 0.629mg/l), Cu (-0.001mg/l to 0.004mg/l), and Cd (0.031mg/l to 0.092mg/l). The physiochemical results showed that the groundwater around the dumpsite may have been contaminated, especially in Dumpsite Hole 1 and Hole 2 at VES4 and VES6 respectively. There are indications for suspected leachate mitigation around the two VES points. Even though, the pH values of 6.4 and 6.2 at the two sounding points were considered to be within the permissible pH range (6.5 to 6.8). The values of other elements present in the groundwater for the samples at other VES points were found to be above permissible WHO and Nigerian Standards for Drinking Water. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=resistivity%20induced%20polarization" title="resistivity induced polarization">resistivity induced polarization</a>, <a href="https://publications.waset.org/abstracts/search?q=chargeability" title=" chargeability"> chargeability</a>, <a href="https://publications.waset.org/abstracts/search?q=landfill" title=" landfill"> landfill</a>, <a href="https://publications.waset.org/abstracts/search?q=leachate" title=" leachate"> leachate</a>, <a href="https://publications.waset.org/abstracts/search?q=contamination" title=" contamination"> contamination</a> </p> <a href="https://publications.waset.org/abstracts/179091/electrical-geophysical-and-physiochemical-assessment-of-the-impact-of-environmental-pollution-on-the-groundwater-potential-of-a-waste-land-fill-at-tudun-murtala-in-nassarawa-local-government-area-kano-state-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/179091.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">62</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">8996</span> Possibilities of Using Chia Seeds in Fermented Beverages Made from Mare’s and Cow’s Milk</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nancy%20Mahmoud">Nancy Mahmoud</a>, <a href="https://publications.waset.org/abstracts/search?q=Joanna%20Teichert"> Joanna Teichert</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nowadays, fermented milk containing probiotic microorganisms is fundamental to human health. The changes in the properties of fermented milk during storage influence the quality and consumer acceptability. This study aimed to evaluate the effect of 1.5 % of chia seeds on the chemical, physical and sensory properties of fermented cow’s and mare’s milk for two weeks at 4°C. The results showed that the pH of cow’s milk drops significantly at the 2nd hour, but mare's milk drops significantly at the 6th hour. The acidity of both types of milk increased as the storage time progressed. Adding chia seeds increased firmness significantly and improved color and consistency. A decrease in brightness (L*), an increase in redness (a*), and yellowness (b*) during storage were observed. Our study showed that the chia seeds have more effect on reducing the brightness of fermented mare milk than fermented cow milk. Analysis of taste and smell parameters showed that after adding chia seeds, the scores changed and became much higher. The sour taste of fermented milk had reduced this positively affected the acceptance of the product. Chia seeds induced beneficial effects on sensory outcomes and enhanced physiochemical properties. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mare%20milk" title="mare milk">mare milk</a>, <a href="https://publications.waset.org/abstracts/search?q=cow%20milk" title=" cow milk"> cow milk</a>, <a href="https://publications.waset.org/abstracts/search?q=feremnted%20milk" title=" feremnted milk"> feremnted milk</a>, <a href="https://publications.waset.org/abstracts/search?q=kefir" title=" kefir"> kefir</a>, <a href="https://publications.waset.org/abstracts/search?q=koumiss" title=" koumiss"> koumiss</a> </p> <a href="https://publications.waset.org/abstracts/163677/possibilities-of-using-chia-seeds-in-fermented-beverages-made-from-mares-and-cows-milk" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/163677.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">98</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">8995</span> Effect of Polyethylene Glycol on Physiochemical Properties of Spherical Agglomerates of Pioglitazone Hydrochloride</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20V.%20Patil">S.

Due to physiochemical similarities between flavour components, the selectivity of this method is not favourable. Besides, the presence of non-volatile compounds such as proteins and carbohydrates may affect the separation of flavours due to their retaining properties. By using a stripping column with structured packing coupled with a gas chromatography, in this work, the overall mass transfer coefficient along with their corresponding equilibrium data was investigated for a model solution consist of water, ethanol, ethyl acetate and isoamyl acetate. Static headspace analysis also was employed to derive equilibrium data for flavours in the presence of beer dry matter. As it was expected ethanol and dry matter showed retention properties; however, the effect of viscosity in mass transfer coefficient was discarded due to the fact that the viscosity of solution decreased during stripping. The effect of ethanol and beer dry matter were mapped to be used for designing stripping could. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=flavour" title="flavour">flavour</a>, <a href="https://publications.waset.org/abstracts/search?q=headspace" title=" headspace"> headspace</a>, <a href="https://publications.waset.org/abstracts/search?q=Henry%E2%80%99s%20coefficient" title=" Henry’s coefficient"> Henry’s coefficient</a>, <a href="https://publications.waset.org/abstracts/search?q=mass%20transfer%20coefficient" title=" mass transfer coefficient"> mass transfer coefficient</a>, <a href="https://publications.waset.org/abstracts/search?q=stripping" title=" stripping"> stripping</a> </p> <a href="https://publications.waset.org/abstracts/80348/stripping-of-flavour-active-compounds-from-aqueous-food-streams-effect-of-liquid-matrix-on-vapour-liquid-equilibrium-in-a-beer-like-solution" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/80348.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">194</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">8992</span> The Role of Initiator in the Synthesis of Poly(Methyl Methacrylate)-Layered Silicate Nanocomposites through Bulk Polymerization</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tsung-Yen%20Tsai">Tsung-Yen Tsai</a>, <a href="https://publications.waset.org/abstracts/search?q=Naveen%20Bunekar"> Naveen Bunekar</a>, <a href="https://publications.waset.org/abstracts/search?q=Ming%20Hsuan%20Chang"> Ming Hsuan Chang</a>, <a href="https://publications.waset.org/abstracts/search?q=Wen-Kuang%20Wang"> Wen-Kuang Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Satoshi%20Onda"> Satoshi Onda</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The structure-property relationship and initiator effect on bulk polymerized poly(methyl methacrylate) (PMMA)–oragnomodified layered silicate nanocomposites was investigated.

The bulk polymerized nanocomposites’ morphology was investigated by X-ray diffraction and transmission electron microscopy. The type of initiator strongly influences the physiochemical properties of the polymer nanocomposite. The thermal degradation of PMMA in the presence of nanofiller was studied. 5 wt% weight loss temperature (T5d) increased as compared to pure PMMA. The peak degradation temperature increased for the nanocomposites. Differential scanning calorimetry and dynamic mechanical analysis were performed to investigate the glass transition temperature and the nature of the constrained region as the reinforcement mechanism respectively.

Normal ethyl-ether was used as solvent in the extraction process. The AOAC method of Analysis was employed in the determination of the physiochemical properties of the oil. The chemical properties of the oil determined include the saponification value, free fatty acid, iodine value, peroxide value and acid value. The physical properties of the oil determined include specific gravity, refractive index, colour, odour, taste and pH. The value obtained for cottonseed oil are saponification value (187mgKOH/g), free fatty acid (5.64mgKOH/g), iodine value (95.2g/100), peroxide value (9.33meq/kg), acid value (11.22mg/KOH/g), pH value (4.62), refractive index (1.46), and specific gravity (0.9) respectively, it has a bland odour, a reddish brown colour and a mild taste. The values obtained for watermelon seed oil are saponification value (83.3mgKOH/g), free fatty acid (6.58mg/KOH/g), iodine value (122.6g/100), peroxide value (5.3meq/kg), acid value (3.74mgKOH/g), pH value (6.3), refractive index (1.47), and specific gravity (0.9) respectively, it has a nutty flavour, a golden yellow colour and a mild taste. From the result obtained, it shows that cottonseed oil has high acid value which shows the stability of the oil and its stability to rancidity. Consequently, watermelon seed oil is order wise. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=extraction" title="extraction">extraction</a>, <a href="https://publications.waset.org/abstracts/search?q=solvent" title=" solvent"> solvent</a>, <a href="https://publications.waset.org/abstracts/search?q=cotton%20seeds" title=" cotton seeds"> cotton seeds</a>, <a href="https://publications.waset.org/abstracts/search?q=watermelon%20seeds" title=" watermelon seeds"> watermelon seeds</a> </p> <a href="https://publications.waset.org/abstracts/26575/comparative-analysis-of-oil-extracts-from-cotton-and-watermelon-seeds" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26575.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">363</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">8989</span> Electrochemical Study of Ti-O Modified Electrode towards Tyrosinase Catalytic Activity</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Riya%20Thomas">Riya Thomas</a>, <a href="https://publications.waset.org/abstracts/search?q=Denis%20Music"> Denis Music</a>, <a href="https://publications.waset.org/abstracts/search?q=Tautgirdas%20Ruzgas"> Tautgirdas Ruzgas</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The detection of tyrosinase holds considerable interest in the domains of food nutrition and human health due to its significant role in causing a detrimental effect on the colour, flavour, and nutritional value of food as well as in the synthesis of melanin causing skin melanoma. Compared to other conventional analytical techniques, electrochemical (EC) sensors are highly promising owing to their quick response, great sensitivity, ease of use, and low cost. Particularly, titania nanoparticle-based electrochemical sensors have drawn special attention in identifying several biomolecules including enzymes, antibodies, and receptors, owing to their enhanced electrocatalytic activity and electron-accepting properties. In this study, Ti-O film-modified electrode is fabricated using reactive magnetron sputtering, and its affinity towards tyrosinase is examined via electrochemical methods. To comprehend the physiochemical and surface properties-governed electrocatalytic activity of modified electrodes, Ti-O films are grown under various compositional ranges and deposition temperature, and their corresponding electrochemical activity towards tyrosinase is studied. Further, to understand the underlying atomistic mechanisms and electronic-scale electrochemical characteristics, density functional theory (DFT) is employed. The main goal of the current work is to determine the correlation between macroscopic measurements and the underlying atomic properties to improve the tyrosinase activity on Ti-O surfaces. Moreover, this work offers an intriguing new perspective on the use of Ti-O-modified electrodes to detect tyrosinase in the areas of clinical diagnosis, skincare, and food science. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=density%20functional%20theory" title="density functional theory">density functional theory</a>, <a href="https://publications.waset.org/abstracts/search?q=electrochemical%20sensor" title=" electrochemical sensor"> electrochemical sensor</a>, <a href="https://publications.waset.org/abstracts/search?q=Ti-O%20film" title=" Ti-O film"> Ti-O film</a>, <a href="https://publications.waset.org/abstracts/search?q=tyrosinase" title=" tyrosinase"> tyrosinase</a> </p> <a href="https://publications.waset.org/abstracts/192153/electrochemical-study-of-ti-o-modified-electrode-towards-tyrosinase-catalytic-activity" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/192153.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">22</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">8988</span> Collagen Scaffold Incorporated with Macrotyloma uniflorum Plant Extracts as a–Burn/Wound Dressing Material, in Vitro and in Vivo Evaluation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Thangavelu%20Muthukumar">Thangavelu Muthukumar</a>, <a href="https://publications.waset.org/abstracts/search?q=Thotapalli%20Parvathaleswara%20Sastry"> Thotapalli Parvathaleswara Sastry</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Collagen is the most abundantly available connective tissue protein, which is being used as a biomaterial for various biomedical applications. Presently, fish wastes are disposed improperly which is causing serious environmental pollution resulting in offensive odour. Fish scales are promising source of Type I collagen. Medicinal plants have been used since time immemorial for treatment of various ailments of skin and dermatological disorders especially cuts, wounds, and burns. Developing biomaterials from the natural sources which are having wound healing properties within the search of a common man is the need of hour, particularly in developing and third world countries. With these objectives in view we have developed a wound dressing material containing fish scale collagen (FSC) incorporated with Macrotyloma uniflorum plant extract (PE). The wound dressing composite was characterized for its physiochemical properties using conventional methods. SEM image revealed that the composite has fibrous and porous surface which helps in transportation of oxygen as well as absorbing wound fluids. The biomaterial has shown 95% biocompatibility with required mechanical strength and has exhibited antimicrobial properties. This biomaterial has been used as a wound dressing material in experimental wounds of rats. The healing pattern was evaluated by macroscopic observations, panimetric studies, biochemical, histopathological observations. The results showed faster healing pattern in the wounds treated with CSPE compared to the other composites used in this study and untreated control. These experiments clearly suggest that CSPE can be used as wound/burn dressing materials. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=collagen" title="collagen">collagen</a>, <a href="https://publications.waset.org/abstracts/search?q=wound%20dressing" title=" wound dressing"> wound dressing</a>, <a href="https://publications.waset.org/abstracts/search?q=Macrotyloma%20uniflorum" title=" Macrotyloma uniflorum"> Macrotyloma uniflorum</a>, <a href="https://publications.waset.org/abstracts/search?q=burn%20dressing" title=" burn dressing"> burn dressing</a> </p> <a href="https://publications.waset.org/abstracts/4243/collagen-scaffold-incorporated-with-macrotyloma-uniflorum-plant-extracts-as-a-burnwound-dressing-material-in-vitro-and-in-vivo-evaluation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/4243.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">417</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">8987</span> Production of Biodiesel from Melon Seed Oil Using Sodium Hydroxide as a Catalyst</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ene%20Rosemary%20Ndidiamaka">Ene Rosemary Ndidiamaka</a>, <a href="https://publications.waset.org/abstracts/search?q=Nwangwu%20Florence%20Chinyere"> Nwangwu Florence Chinyere</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The physiochemical properties of the melon seed oil was studied to determine its potentials as viable feed stock for biodisel production.

The melon seed oil was characterized for specific gravity, pH, ash content, iodine value, acid value, saponification value, peroxide value, free fatty acid value, flash point, viscosity, and refractive index using standard methods. The melon seed oil had very high oil content. Specific gravity and flash point of the oil is satisfactory.

The biscuits that were developed incorporating them had 50% wheat flour and 50% jackfruit seed flour and 50% cassava flours as the major composition, apart from the other general ingredients use in making biscuits. Various trials of compositions were made for baking to get the overall desirable acceptability in biscuits through sensory evaluation. Finally, the best composition of ingredients was selected to make the biscuits, and hence studies were done accordingly to compare it with the properties of their respective raw flours. The results showed that the proximate composition of the biscuits fared better than that of their respective flours: There was a decrease in the Moisture content of both Jackfruit Seed Biscuits and Cassava Biscuits to 4.5% and 6.7% than that of their respective raw flours (8 and 12%).

The present work has emphasized on the preparation, characterization, and biopharmaceutical evaluation of co-crystal of BCS Class II anti-osteoarthritis drug, Oxaprozin (OXA) with aspartic acid (ASPA) as co-former. The co-crystals were prepared through the mechanochemical solvent drop grinding method. Characterization of the prepared co-crystal (OXA-ASPA) was done by using analytical tools such as differential scanning calorimetry (DSC), Fourier transform infrared spectroscopy (FT-IR), powder X-ray diffraction (PXRD). DSC thermogram of OXA-ASPA cocrystal showed a single sharp melting endotherm at 235 ºC, which was between the melting peaks of the drug and the counter molecules suggesting the formation of a new phase which is a co-crystal that was further confirmed by using other analytical techniques. FT-IR analysis of OXA-ASPA cocrystal showed a shift in a hydroxyl, carbonyl, and amine peaks as compared to pure drugs indicating all these functional groups are participating in cocrystal formation. The appearance of new peaks in the PXRD pattern of cocrystals in comparison to individual components showed that a new crystalline entity has been formed. The Crystal structure of cocrystal was determined using material studio software (Biovia) from PXRD. The equilibrium solubility study of OXA-ASPA showed improvement in solubility as compared to pure drug. Therefore, it was envisioned to prepare the co-crystal of oxaprozin with a suitable conformer to modulate its physiochemical properties and consequently, the biopharmaceutical parameters. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cocrystals" title="cocrystals">cocrystals</a>, <a href="https://publications.waset.org/abstracts/search?q=coformer" title=" coformer"> coformer</a>, <a href="https://publications.waset.org/abstracts/search?q=oxaprozin" title=" oxaprozin"> oxaprozin</a>, <a href="https://publications.waset.org/abstracts/search?q=solubility" title=" solubility"> solubility</a> </p> <a href="https://publications.waset.org/abstracts/109501/designing-preparation-and-structural-evaluation-of-co-crystals-of-oxaprozin" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/109501.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">115</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">8984</span> Effects of SRT and HRT on Treatment Performance of MBR and Membrane Fouling </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20I.%20Aida%20Isma">M.

The objectives of the study were to investigate the effects of SRT and HRT on membrane fouling. A comparative analysis was carried out for physiochemical quality parameters (turbidity, suspended solids, COD, NH3-N and PO43-). Scanning electron microscopy (SEM), energy diffusive X-ray (EDX) analyzer and particle size distribution (PSD) were used to characterize the membrane fouling properties. The influence of SRT on the quality of effluent, activated sludge quality, and membrane fouling were also correlated. Lower membrane fouling and slower rise in trans-membrane pressure (TMP) were noticed at the longest SRT and HRT of 30d and 12h, respectively. Increasing SRT results in noticeable reduction of dissolved organic matters. The best removal efficiencies of COD, TSS, NH3-N and PO43- were 93%, 98%, 80% and 30% respectively. The high HRT with shorter SRT induced faster fouling rate. The main fouling resistance was cake layer. The most severe membrane fouling was observed at SRT and HRT of 4 and 12, respectively with thickness cake layer of 17 μm as reflected by higher TMP, lower effluent removal and thick sludge cake layer. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=membrane%20bioreactor" title="membrane bioreactor">membrane bioreactor</a>, <a href="https://publications.waset.org/abstracts/search?q=SRT" title=" SRT"> SRT</a>, <a href="https://publications.waset.org/abstracts/search?q=HRT" title=" HRT"> HRT</a>, <a href="https://publications.waset.org/abstracts/search?q=fouling" title=" fouling"> fouling</a> </p> <a href="https://publications.waset.org/abstracts/6152/effects-of-srt-and-hrt-on-treatment-performance-of-mbr-and-membrane-fouling" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/6152.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">526</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">8983</span> Soil Degradation Resulting from Migration of Ion Leachate in Gosa Dumpsite, Abuja</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20Ebisintei">S.

It was done to assess the health and environmental pollution consequences caused by heavy metals’ concentration in the soil on inhabitants around the settlement. Soil samples collected from four cardinal points and at the center during the dry and wet season were pretreated, digested and heavy metal concentrations present were analyzed using Atomic Absorption Spectrophotometer. The concentrations of Pb, Cu, Mn, Ni, and Cr, were determined and also for control sample obtained 300 m away from the dumpsite. Water samples were collected from three wells to test for physiochemical properties of pH, COD, BOD, DO, hardness, conductivity, and alkalinity. The result showed a significant difference in concentration of toxic heavy metals in the dumpsite as compared to the control sample. A mathematical model was developed to predict the heavy metal concentrations beyond the sampling point. The results indicate that metal concentrations in both dry and wet season were above the WHO, and SON set standards. The trend, if unrestrained, portends danger to human life, reduces agricultural productivity and sustainability. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=soil%20degradation" title="soil degradation">soil degradation</a>, <a href="https://publications.waset.org/abstracts/search?q=ion%20leachate" title=" ion leachate"> ion leachate</a>, <a href="https://publications.waset.org/abstracts/search?q=productivity" title=" productivity"> productivity</a>, <a href="https://publications.waset.org/abstracts/search?q=environment" title=" environment"> environment</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainability" title=" sustainability"> sustainability</a> </p> <a href="https://publications.waset.org/abstracts/22460/soil-degradation-resulting-from-migration-of-ion-leachate-in-gosa-dumpsite-abuja" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22460.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">347</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">8982</span> MCD-017: Potential Candidate from the Class of Nitroimidazoles to Treat Tuberculosis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gurleen%20Kour">Gurleen Kour</a>, <a href="https://publications.waset.org/abstracts/search?q=Mowkshi%20Khullar"> Mowkshi Khullar</a>, <a href="https://publications.waset.org/abstracts/search?q=B.%20K.%20Chandan"> B.

Apart from in-vitro potency against the target, physiochemical properties and pharmacokinetic properties play an imperative role in the process of drug discovery. We have identified novel nitroimidazole derivatives with potential activity against mycobacterium tuberculosis. One lead candidates, MCD-017, which showed potent activity against H37Rv strain (MIC=0.5µg/ml) and was further evaluated in the process of drug development. Methods: Basic physicochemical parameters like solubility and lipophilicity (LogP) were evaluated. Thermodynamic solubility was determined in PBS buffer (pH 7.4) using LC/MS-MS. The partition coefficient (Log P) of the compound was determined between octanol and phosphate buffered saline (PBS at pH 7.4) at 25°C by the microscale shake flask method. The compound followed Lipinski’s rule of five, which is predictive of good oral bioavailability and was further evaluated for metabolic stability. In-vitro metabolic stability was determined in rat liver microsomes. The hepatotoxicity of the compound was also determined in HepG2 cell line. In vivo pharmacokinetic profile of the compound after oral dosing was also obtained using balb/c mice. Results: The compound exhibited favorable solubility and lipophilicity. The physical and chemical properties of the compound were made use of as the first determination of drug-like properties. The compound obeyed Lipinski’s rule of five, with molecular weight < 500, number of hydrogen bond donors (HBD) < 5 and number of hydrogen bond acceptors(HBA) not more then 10. The log P of the compound was less than 5 and therefore the compound is predictive of exhibiting good absorption and permeation. Pooled rat liver microsomes were prepared from rat liver homogenate for measuring the metabolic stability. 99% of the compound was not metabolized and remained intact. The compound did not exhibit cytoxicity in hepG2 cells upto 40 µg/ml. The compound revealed good pharmacokinetic profile at a dose of 5mg/kg administered orally with a half life (t1/2) of 1.15 hours, Cmax of 642ng/ml, clearance of 4.84 ml/min/kg and a volume of distribution of 8.05 l/kg. Conclusion : The emergence of multi drug resistance (MDR) and extensively drug resistant (XDR) Tuberculosis emphasize the requirement of novel drugs active against tuberculosis. Thus, the need to evaluate physicochemical and pharmacokinetic properties in the early stages of drug discovery is required to reduce the attrition associated with poor drug exposure. In summary, it can be concluded that MCD-017 may be considered a good candidate for further preclinical and clinical evaluations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mycobacterium%20tuberculosis" title="mycobacterium tuberculosis">mycobacterium tuberculosis</a>, <a href="https://publications.waset.org/abstracts/search?q=pharmacokinetics" title=" pharmacokinetics"> pharmacokinetics</a>, <a href="https://publications.waset.org/abstracts/search?q=physicochemical%20properties" title=" physicochemical properties"> physicochemical properties</a>, <a href="https://publications.waset.org/abstracts/search?q=hepatotoxicity" title=" hepatotoxicity"> hepatotoxicity</a> </p> <a href="https://publications.waset.org/abstracts/31867/mcd-017-potential-candidate-from-the-class-of-nitroimidazoles-to-treat-tuberculosis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/31867.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">457</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">8981</span> Structural and Thermodynamic Properties of MnNi</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=N.%20Benkhettoua">N.

This emerges as a promising candidate for photoelectrochemical (PEC) water splitting due to its favorable physiochemical properties of the narrow band gap (2.1–2.2 eV), chemical stability, nontoxicity, abundance, and low cost. However, inherent limitations such as short hole diffusion length (2–4 nm), high charge recombination rate, and slow oxygen evolution reaction kinetics inhibit the PEC performances of a-Fe2O3 photoanodes. As such, given the narrow bandgap enabling excellent optical absorption, increased charge carrier density and accelerated surface oxidation reaction kinetics become the key points for improved photoelectrochemical performances for a-Fe2O3 photoanodes and metal ion doping as an effective way to promote charge transfer by increasing donor density and improving the electronic conductivity of a-Fe2O3. Hematite attracts enormous efforts with a number of metal ions (Ti, Zr, Sn, Pt ,etc.) as dopants. A facile deposition-annealing process showed greatly enhanced PEC performance due to the increased donor density and reduced electron-hole recombination at the time scale beyond a few picoseconds. Zr doping was also found to enhance the PEC performance of a-Fe2O3 nanorod arrays by reducing the rate of electron-hole recombination. Slow water oxidation reaction kinetics, another main factor limiting the PEC water splitting efficiency of aFe2O3 as photoanodes, was previously found to be effectively improved by surface treatment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=deposition-annealing" title="deposition-annealing">deposition-annealing</a>, <a href="https://publications.waset.org/abstracts/search?q=hematite" title=" hematite"> hematite</a>, <a href="https://publications.waset.org/abstracts/search?q=metal%20ion%20doping" title=" metal ion doping"> metal ion doping</a>, <a href="https://publications.waset.org/abstracts/search?q=nanorod" title=" nanorod"> nanorod</a> </p> <a href="https://publications.waset.org/abstracts/94270/absorption-and-carrier-transport-properties-of-doped-hematite" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/94270.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">220</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">8979</span> Synthesis and Physiochemical Properties of 3-Propanenitrile Imidazolium - Based Dual Functionalized Ionic Liquids Incorporating Dioctyl Sulfosuccinate Anion</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abobakr%20Khidir%20Ziyada">Abobakr Khidir Ziyada</a>, <a href="https://publications.waset.org/abstracts/search?q=Cecilia%20Devi%20Wilfred"> Cecilia Devi Wilfred</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the present work, a new series of 3-propanenitrile imidazolium-based Room Temperature Ionic Liquids (RTILs), incorporating dioctyl sulfosuccinate (DOSS) were prepared by reacting imidazole with acrylonitrile and then reacting the product with allyl chloride, 2-chloroethanol, and benzyl chloride. After the reaction had been completed, metathesis reaction was carried out using sodium dioctyl sulfosuccinate. The densities and viscosities of the present RTILs were measured at atmospheric pressure at T=293.15 to 353.15 K, the refractive index was measured at T=293.15 to 333.15 K, whereas, the start and decomposition temperatures were determined at heating rate 10°C. min^-1. The thermal expansion coefficient, densities at a range of temperatures and pressures, molecular volume, molar refraction, standard entropy and the lattice energy of these RTILs were also estimated. The present RTILs showed higher densities, similar refractive indices, and higher viscosities compared to the other 1-alkyl-3-propanenitrile imidazolium-based RTILs. The densities of the present synthesized RTILs are lower compared to the other nitrile-functionalized ILs. These present RTILs showed a weak temperature dependence on the thermal expansion coefficients, αp=5.0 × 10^−4 to 7.50 × 10−4 K^-1. Empirical correlations were proposed to represent the present data on the physical properties. The lattice energy for the present RTILs was similar to other nitrile–based imidazolium RTILs. The present RTILs showed very high molar refraction when compared similar RTILs incorporating other anions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dioctyl%20sulfosuccinate" title="dioctyl sulfosuccinate">dioctyl sulfosuccinate</a>, <a href="https://publications.waset.org/abstracts/search?q=nitrile%20ILs" title=" nitrile ILs"> nitrile ILs</a>, <a href="https://publications.waset.org/abstracts/search?q=3-propanenitrile" title=" 3-propanenitrile"> 3-propanenitrile</a>, <a href="https://publications.waset.org/abstracts/search?q=anion" title=" anion"> anion</a>, <a href="https://publications.waset.org/abstracts/search?q=room%20temperature%20ionic%20liquids" title=" room temperature ionic liquids"> room temperature ionic liquids</a>, <a href="https://publications.waset.org/abstracts/search?q=RTIL" title=" RTIL "> RTIL </a> </p> <a href="https://publications.waset.org/abstracts/24255/synthesis-and-physiochemical-properties-of-3-propanenitrile-imidazolium-based-dual-functionalized-ionic-liquids-incorporating-dioctyl-sulfosuccinate-anion" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24255.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">337</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">8978</span> The Burden and the Consequences of Waste Management in Nigeria: Geophysical Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Joseph%20Omeiza%20Alao">Joseph Omeiza Alao</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The wobbly state of waste management and the high level of environmental irresponsibility is a threat to environmental security, which invariably endangered public health, regional groundwater systems and atmospheric condition. The dumping of waste materials in water bodies and gutters and the frequent burning of waste materials heaped at dumpsites as well depict the highest level of environmental indiscipline. These unruly human factors have compelled this study to apply four different techniques for environmental impact assessment and the possible public health risks of poor waste management in Nigeria. The techniques include a geophysical survey (resistivity data acquisition), dispatched questionnaire surveys, physiochemical water analysis and a physical survey of several dumpsites. While the resistivity data indicates high-level dumpsite leachate invading the ground soil down to the water table, the physiochemical water analysis depicts high content of BOD (401 – 711) mg/l, COD (731 – 1312) mg/l, TDS (419 – 1871) mg/l and heavy metals (0.014 – 1.971) mg/l present in the regional groundwater systems, which have altered the chemistry of the regional groundwater. The resistivity data shows that the overburdened soil layer overlaying the regional groundwater systems was very low (4.5 Ωm – 151 Ωm) as against the existing data (180 Ωm – 3500 Ωm). However, the physical surveys and the dispatched questionnaire surveys explore the depth of environmental irresponsibility among the citizen. While the imprints of gross environmental indiscipline may be absolutely irreversible, adequate knowledge of the environmental implications of careless waste disposal. After a critical examination of the current waste management strategies in Nigeria, the study suggests a future direction for environmental security and sustainability. Several influential regional factors, such as geology, climatic conditions, and hydrology, were also discussed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=groundwater" title="groundwater">groundwater</a>, <a href="https://publications.waset.org/abstracts/search?q=environmental%20indiscipline" title=" environmental indiscipline"> environmental indiscipline</a>, <a href="https://publications.waset.org/abstracts/search?q=waste%20management" title=" waste management"> waste management</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20analysis" title=" water analysis"> water analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=leachate%20plumes" title=" leachate plumes"> leachate plumes</a>, <a href="https://publications.waset.org/abstracts/search?q=public%20health" title=" public health"> public health</a> </p> <a href="https://publications.waset.org/abstracts/166303/the-burden-and-the-consequences-of-waste-management-in-nigeria-geophysical-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/166303.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">68</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">8977</span> Preparation and Application of Biocompatible Nanobioactive Glass as Therapeutic Agents for Bone Tissue Engineering</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=P.%20Shrivastava">P.

Nanobioactive glass has been synthesized by sol gel method having a combination of silicon, calcium and phosphorous in the molar ratio of 75:21:4. The prepared particles were analyzed for surface morphology by FEG SEM and FEG TEM. Physiochemical properties were investigated using ICP AES, FTIR spectroscopy and X-ray diffraction (XRD) techniques. To ascertain their use for therapeutic use, biocompatibility evaluation of the particles was done by performing soaking studies in SBF and in vitro cell culture studies on MG63 cell lines. Cell morphology was observed by FE SEM and phase contrast microscopy. Nanobioactive glasses (NBG) thus prepared were of 30-200 nm in size, which makes them suitable for nano-biomedical applications. The spherical shape of the particles imparts high surface to volume ratio, promoting fast growth of hydroxyapatite (HA), which is the mineral component of bone. As evaluated by in vitro cell culture studies the NBG was found to enhance the surface activation which enhances osteoblast adhesion. This is an essential parameter to improve bone tissue integration, thereby making nanobioactive glass therapeutically suitable for correcting bone defects. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biocompatibility" title="biocompatibility">biocompatibility</a>, <a href="https://publications.waset.org/abstracts/search?q=bone%20tissue%20engineering" title=" bone tissue engineering"> bone tissue engineering</a>, <a href="https://publications.waset.org/abstracts/search?q=hydroxyapatite" title=" hydroxyapatite"> hydroxyapatite</a>, <a href="https://publications.waset.org/abstracts/search?q=nanobioactive%20glass" title=" nanobioactive glass"> nanobioactive glass</a> </p> <a href="https://publications.waset.org/abstracts/14477/preparation-and-application-of-biocompatible-nanobioactive-glass-as-therapeutic-agents-for-bone-tissue-engineering" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14477.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">456</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">8976</span> Extraction of Inulin from Cichorium Intybus and Its Application as Fat Replacer in Yoghurt</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hafiz%20Khuram%20Wasim%20Aslam">Hafiz Khuram Wasim Aslam</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Saeed"> Muhammad Saeed</a>, <a href="https://publications.waset.org/abstracts/search?q=Azam%20Shakeel"> Azam Shakeel</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Inam%20Ur%20Raheem"> Muhammad Inam Ur Raheem</a>, <a href="https://publications.waset.org/abstracts/search?q=Moazzam%20Rafiq%20Khan"> Moazzam Rafiq Khan</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Atif%20Randhawa"> Muhammad Atif Randhawa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Inulin is significant ingredient used in food industry that functions technologically as a fat replacer often without compromising taste and texture. In this study inulin was extracted from the chicory roots and the effect of inulin addition as a fat replacer on the physiochemical, microbiological and sensory properties of non-fat yogurt was investigated. The supplementation of chicory inulin reduced the magnitude of firmness in comparison with non-inulin ¬supplemented non-fat yoghurt. Higher values of acidity were observed due to the more microbial fermentation in the inulin containing yogurt as compared to non-inulin yogurt and were in the range of 0.56 to 0.75 during storage days. Syneresis in control sample increased from 43.9% to 47.9% during the storage study. However inulin addition at different treatment enhanced syneresis from 44.5% to 47.6%. Inulin addition at various concentrations caused an increase in the TPC due to its probiotic effect. No effects of inuline addition on fat and protein contents were observed. Non-fat yoghurt supplemented with inulin demonstrated sensory behavior better than that of the control yoghurt. The most important effect of the addition of inulin to non-fat yoghurt is an increase in the sensory attributes appearance, body and texture, taste and mouth feel, overall acceptability. On an average, yoghurt supplemented with 1 to 2% inulin was better in overall acceptance as compared to control yoghurt. <p class="card-text"><strong>Keywords:</strong> <a
