Commonly, wood stains are petroleum-based and synthetically derived. Notably, commercially accessible wood stains exhibit around 4% greater volatility than the formulated wood stain (FWS), potentially indicating a heightened environmental impact. The application of FWS does not significantly affect the performance of polyurethane varnish. The impact of incorporating an FWS when was applied to Gmelina arborea wood sample, the initial lightness value (L*) of 68.5, a* 7.7, b* 29.2 decreased to 44.36, a* 23.49, b* 32.60, where a* denotes the red/ green value, b* denotes the yellow/ blue, indicating a shift towards darker shades. This alteration in lightness suggests that the FWS contains compounds or pigments that effectively absorb or scatter light, resulting in a change in the perceived color and visual appearance of the wood surface. Moreover, the successful formulation of an eco-friendly natural wood stain is detailed, presenting a promising alternative. This method finds applicability in the domains of furniture and handicraft creation, offering a sustainable choice for creative artisans. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=formulated%20wood%20stain%20%28FWS%29" title="formulated wood stain (FWS)">formulated wood stain (FWS)</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20dyes" title=" natural dyes"> natural dyes</a>, <a href="https://publications.waset.org/abstracts/search?q=wood%20stains" title=" wood stains"> wood stains</a>, <a href="https://publications.waset.org/abstracts/search?q=eco-friendly%20natural%20wood%20stain" title=" eco-friendly natural wood stain"> eco-friendly natural wood stain</a>, <a href="https://publications.waset.org/abstracts/search?q=" title=""></a> </p> <a href="https://publications.waset.org/abstracts/171729/sustainable-wood-stains-derived-from-natural-dyes-for-green-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/171729.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">1480</span> The Effect of Transparent Oil Wood Stain on the Colour Stability of Spruce Wood during Weathering </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eliska%20Oberhofnerova">Eliska Oberhofnerova</a>, <a href="https://publications.waset.org/abstracts/search?q=Milos%20Panek"> Milos Panek</a>, <a href="https://publications.waset.org/abstracts/search?q=Stepan%20Hysek"> Stepan Hysek</a>, <a href="https://publications.waset.org/abstracts/search?q=Martin%20Lexa"> Martin Lexa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nowadays the use of wood, both indoors and outdoors, is constantly increasing. However wood is a natural organic material and in the exterior is subjected to a degradation process caused by abiotic factors (solar radiation, rain, moisture, wind, dust etc.). This process affects only surface layers of wood but neglecting some of the basic rules of wood protection leads to increased possibility of biological agents attack and thereby influences a function of the wood element. The process of wood degradation can be decreased by proper surface treatment, especially in the case of less naturally durable wood species, as spruce. Modern coating systems are subjected to many requirements such as colour stability, hydrophobicity, low volatile organic compound (VOC) content, long service life or easy maintenance. The aim of this study is to evaluate the colour stability of spruce wood (Picea abies), as the basic parameter indicating the coating durability, treated with two layers of transparent natural oil wood stain and exposed to outdoor conditions. The test specimens were exposed for 2 years to natural weathering and 2000 hours to artificial weathering in UV-chamber. The colour parameters were measured before and during exposure to weathering by the spectrophotometer according to CIELab colour space. The comparison between untreated and treated wood and both testing procedures was carried out. The results showed a significant effect of coating on the colour stability of wood, as expected. Nevertheless, increasing colour changes of wood observed during the exposure to weathering differed according to applied testing procedure - natural and artificial. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=colour%20stability" title="colour stability">colour stability</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20and%20artificial%20weathering" title=" natural and artificial weathering"> natural and artificial weathering</a>, <a href="https://publications.waset.org/abstracts/search?q=spruce%20wood" title=" spruce wood"> spruce wood</a>, <a href="https://publications.waset.org/abstracts/search?q=transparent%20coating" title=" transparent coating"> transparent coating</a> </p> <a href="https://publications.waset.org/abstracts/73590/the-effect-of-transparent-oil-wood-stain-on-the-colour-stability-of-spruce-wood-during-weathering" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/73590.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">1479</span> Study on Parallel Shear Stress of Cement-Wood Composites Using Pinus sp. and Eucalyptus sp. in natura and Treated with CCA</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rodrigo%20D.%20S.%20Oliveira">Rodrigo D.

An environmentally friendly alternative is the use of this waste for the production of cement-wood composites. The aim of this work was to study the possibility of using wood treated with CCA (Chromated Cooper Arsenate) in cement-wood. Specimens of Pinus sp. and Eucalyptus sp. were produced with wood raw in natura and treated with CCA. A test was performed to determine the parallel shear stress of samples after 14 days of drying, according to the Brazilian Standard NBR-7215/97. Based on the analyzed results it is concluded that the use of wood treated with CCA is not feasible in cement-wood production, because the composite samples of treated wood showed lower mechanical strength in shear stress than those with wood in natura. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=waste%20recovery" title="waste recovery">waste recovery</a>, <a href="https://publications.waset.org/abstracts/search?q=wood%20composites" title=" wood composites"> wood composites</a>, <a href="https://publications.waset.org/abstracts/search?q=cement-wood" title=" cement-wood"> cement-wood</a>, <a href="https://publications.waset.org/abstracts/search?q=wood%20preservation" title=" wood preservation"> wood preservation</a>, <a href="https://publications.waset.org/abstracts/search?q=chromated%20copper%20arsenate" title=" chromated copper arsenate"> chromated copper arsenate</a> </p> <a href="https://publications.waset.org/abstracts/13252/study-on-parallel-shear-stress-of-cement-wood-composites-using-pinus-sp-and-eucalyptus-sp-in-natura-and-treated-with-cca" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/13252.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">620</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">1478</span> Improving Fire Resistance of Wood and Wood-Based Composites and Fire Testing Systems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nadir%20Ayrilmis">Nadir Ayrilmis</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Wood and wood-based panels are one of the oldest structural materials used in the construction industry due to their significant advantages such as good mechanical properties, low density, renewable material, low-cost, recycling, etc. However, they burn when exposed to a flame source or high temperatures.

Wood is widely used for many things range from building materials to furniture materials. This makes the forest area in Indonesia dropped dramatically, it is estimated that the area of Indonesiaan forest in 2020 will be only about 16 million hectares. The more forest in Indonesia loss, people are required to look for another material to subtitute wood for the furniture. Jepara, a city with the largest furniture industry in Indonesia, requires a large supply of wood, it can reach 300.000 – 500.000 cubic meters per year. Most of the furniture in Jepara use teak, mahogany, and rosewood. Though teak wood is a rare species that must be protected. Today the availability of bamboo in Indonesia is very big. With cheap price, and the period of rapid growth makes bamboo can be used as a substitute for wood for the furniture industry in the future. By making use bamboo to make wood bamboo composite to replace the use of wood for furniture material. This paper is about the use of bamboo as a substitute for wood bamboo composite for the furniture industry. Expected in future, wood can be replaced by a wood bamboo composite. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bamboo" title="bamboo">bamboo</a>, <a href="https://publications.waset.org/abstracts/search?q=composite" title=" composite"> composite</a>, <a href="https://publications.waset.org/abstracts/search?q=furniture" title=" furniture"> furniture</a>, <a href="https://publications.waset.org/abstracts/search?q=wood" title=" wood"> wood</a> </p> <a href="https://publications.waset.org/abstracts/54368/the-utilization-of-bamboo-for-wood-bamboo-composite-in-lieu-of-materials-furniture-case-study-of-furniture-industry-in-jepara-indonesia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/54368.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">376</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">1476</span> Experimental Investigation of Stain Removal Performance of Different Types of Top Load Washing Machines with Textile Mechanical Damage Consideration</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <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=Muhammed%20Emin%20%C3%87oban"> Muhammed Emin Çoban</a>, <a href="https://publications.waset.org/abstracts/search?q=Song%C3%BCl%20Byraktar"> Songül Byraktar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> One of the main targets of the washing machine is to remove any dirt and stains from the clothes. 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">1475</span> Single-Element Simulations of Wood Material in LS-DYNA</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ren%20Zuo%20Wang">Ren Zuo Wang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, in order to investigate the behavior of the wood structure, the non-linearity of wood material model in LS-DYNA is adopted.

Wood apple gum is widely used in the food, coating, and pharmaceutical industries. Wood apple gum was a major component in ancient Sri Lankan coating technology as well. It is also used as a suspending agent in liquid syrups and food ingredients such as sauces, emulsifiers, and stabilizers. Industrial applications include adhesives for labeling and packaging, as well as paint binder. It is also used in the production of paper and cosmetics. Extraction of wood apple gum is an important step in ensuring maximum benefits for various uses. It is apparent that an abundance of untapped potential lies in wood apple gum if people are able to mass produce them. Hence, the current study uses a two-factor factorial design with two major variables and four replications to investigate the best gum-extracting tapping system for Wood apple gum. This study's findings will be useful to Wood apple cultivators, researchers, and gum-based industries alike. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=wood%20apple%20gum" title="wood apple gum">wood apple gum</a>, <a href="https://publications.waset.org/abstracts/search?q=limonia%20acidissima%20l." title=" limonia acidissima l."> limonia acidissima l.</a>, <a href="https://publications.waset.org/abstracts/search?q=tapping" title=" tapping"> tapping</a>, <a href="https://publications.waset.org/abstracts/search?q=tapping%20cuts" title=" tapping cuts"> tapping cuts</a> </p> <a href="https://publications.waset.org/abstracts/174725/analyzing-the-efficiency-of-several-gum-extraction-tapping-systems-for-wood-apple-trees" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/174725.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">75</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">1473</span> Fermentation of Wood Waste by Treating with H₃PO₄-Acetone for Bioethanol Production</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Deokyeong%20Choe">Deokyeong Choe</a>, <a href="https://publications.waset.org/abstracts/search?q=Keonwook%20Nam"> Keonwook Nam</a>, <a href="https://publications.waset.org/abstracts/search?q=Young%20Hoon%20Roh"> Young Hoon Roh </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Wood waste is a potentially significant resource for economic and environment-friendly recycling. Wood waste represents a key sustainable source of biomass for transformation into bioethanol. Unfortunately, wood waste is highly recalcitrant for biotransformation, which limits its use and prevents economically viable conversion into bioethanol. As a result, an effective pretreatment is necessary to degrade cellulose of the wood waste, which improves the accessibility of cellulase. In this work, a H₃PO₄-acetone pretreatment was selected among the various pretreatment methods and used to dissolve cellulose and lignin. When the H₃PO₄ and acetone were used, 5–6% of the wood waste was found to be very appropriate for saccharification. Also, when the enzymatic saccharification was conducted in the mixture of the wood waste and 0.05 M citrate buffer solution, glucose and xylose were measured to be 80.2 g/L and 9.2 g/L respectively. Furthermore, ethanol obtained after 70 h of fermentation by S. cerevisiae was 30.4 g/L. As a result, the conversion yield from wood waste to bioethanol was calculated to be 57.4%. These results show that the pretreated wood waste can be used as good feedstocks for bioethanol production and that the H₃PO₄-acetone pretreatment can effectively increase the yield of ethanol production. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=wood%20waste" title="wood waste">wood waste</a>, <a href="https://publications.waset.org/abstracts/search?q=H%E2%82%83PO%E2%82%84-acetone" title=" H₃PO₄-acetone"> H₃PO₄-acetone</a>, <a href="https://publications.waset.org/abstracts/search?q=bioethanol" title=" bioethanol"> bioethanol</a>, <a href="https://publications.waset.org/abstracts/search?q=fermentation" title=" fermentation "> fermentation </a> </p> <a href="https://publications.waset.org/abstracts/84149/fermentation-of-wood-waste-by-treating-with-h3po4-acetone-for-bioethanol-production" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/84149.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">571</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">1472</span> Rubber Wood as a Potential Biomass Feedstock for Biochar via Slow Pyrolysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Adilah%20Shariff">Adilah Shariff</a>, <a href="https://publications.waset.org/abstracts/search?q=Radin%20Hakim"> Radin Hakim</a>, <a href="https://publications.waset.org/abstracts/search?q=Nurhayati%20Abdullah"> Nurhayati Abdullah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Utilisation of biomass feedstock for biochar has received increasing attention because of their potential for carbon sequestration and soil amendment. The aim of this study is to investigate the characteristics of rubber wood as a biomass feedstock for biochar via slow pyrolysis process. This was achieved by using proximate, ultimate, and thermogravimetric analysis (TGA) as well as heating value, pH and lignocellulosic determination. Rubber wood contains 4.13 mf wt.% moisture, 86.30 mf wt.% volatile matter, 0.60 mf wt.% ash content, and 13.10 mf wt.% fixed carbon. The ultimate analysis shows that rubber wood consists of 44.33 mf wt.% carbon, 6.26 mf wt.% hydrogen, 19.31 mf wt.% nitrogen, 0.31 mf wt.% sulphur, and 29.79 mf wt.% oxygen. The higher heating value of rubber wood is 22.5 MJ/kg, and its lower heating value is 21.2 MJ/kg. At 27 °C, the pH value of rubber wood is 6.83 which is acidic. The lignocellulosic analysis revealed that rubber wood composition consists of 2.63 mf wt.% lignin, 20.13 mf wt.% cellulose, and 65.04 mf wt.% hemicellulose. The volatile matter to fixed carbon ratio is 6.58. This led to a biochar yield of 25.14 wt.% at 500 °C. Rubber wood is an environmental friendly feedstock due to its low sulphur content. Rubber wood therefore is a suitable and a potential feedstock for biochar production via slow pyrolysis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biochar" title="biochar">biochar</a>, <a href="https://publications.waset.org/abstracts/search?q=biomass" title=" biomass"> biomass</a>, <a href="https://publications.waset.org/abstracts/search?q=rubber%20wood" title=" rubber wood"> rubber wood</a>, <a href="https://publications.waset.org/abstracts/search?q=slow%20pyrolysis" title=" slow pyrolysis"> slow pyrolysis</a> </p> <a href="https://publications.waset.org/abstracts/53243/rubber-wood-as-a-potential-biomass-feedstock-for-biochar-via-slow-pyrolysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/53243.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">319</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">1471</span> Assessment of Hygroscopic Characteristics of Hevea brasiliensis Wood</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=John%20Tosin%20Aladejana">John Tosin Aladejana</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Wood behave differently under different environmental conditions. The knowledge of the hygroscopic nature of wood becomes a key factor in selecting wood for use and required treatment. This study assessed the hygroscopic behaviour of Hevea brasiliensis (Rubber) wood. Void volume, volumetric swelling in the tangential, radial and longitudinal directions and volumetric shrinkage were used to assess the response of the wood when loosing or taking up moisture. Hevea brasiliensis wood samples cut into 20 × 20 × 60 mm taken longitudinally and transversely were used for the study and dried in the oven at 103 ± 2⁰C. The mean values for moisture content in green Hevea brasiliensis wood were 49.74 %, 51.14 % and 54.36 % for top, middle and bottom portion respectively while 51.77 %, 50.02 % and 53.45 % were recorded for outer, middle and inner portions respectively for the tree. The values obtained for volumetric shrinkage and swelling indicated that shrinkage and swelling were higher at the top part of H. brasiliensis. It was also observed that the longitudinal shrinkage was negligible while tangential direction showed the highest shrinkage among the wood direction. The values of the void volume obtained were 43.0 %, 39.0 % and 38.0 % at the top, middle and bottom respectively. The result obtained showed clarification on the wood density of hevea brasiliensis based on the position and portion of the wood species and the variation in moisture content, void volume, volumetric shrinkage and swelling were also revealed. This will provide information in the process of drying hevea brasiliensis wood to ensure better wood quality devoid of defects. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=moisture%20content" title="moisture content">moisture content</a>, <a href="https://publications.waset.org/abstracts/search?q=shrinkage" title=" shrinkage"> shrinkage</a>, <a href="https://publications.waset.org/abstracts/search?q=swelling" title=" swelling"> swelling</a>, <a href="https://publications.waset.org/abstracts/search?q=void%20volume" title=" void volume"> void volume</a> </p> <a href="https://publications.waset.org/abstracts/78996/assessment-of-hygroscopic-characteristics-of-hevea-brasiliensis-wood" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/78996.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">274</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">1470</span> Conversion of Tropical Wood to Bio-oil and Charcoal by Using the Process of Pyrolysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kittiphop%20Promdee">Kittiphop Promdee</a>, <a href="https://publications.waset.org/abstracts/search?q=Somruedee%20Satitkune"> Somruedee Satitkune</a>, <a href="https://publications.waset.org/abstracts/search?q=Chakkrich%20Boonmee"> Chakkrich Boonmee</a>, <a href="https://publications.waset.org/abstracts/search?q=Tharapong%20Vitidsant"> Tharapong Vitidsant</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Conversion of tropical wood using the process of pyrolysis, which converts tropical wood into fuel products, i.e. bio-oil and charcoal.

The removal is very expensive due to the high cost of normal adsorbents. Lignocellulosic materials and mainly treated materials have proven to be a good solution for this problem. Adsorption tests were performed at different pH, different times and with varying concentrations. Results show that is at pH 3 that treated wood absorbs more chromium ranging from 70% (2h treatment) to almost 100% (12 h treatment) much more than untreated wood with less than 40%. Most of the adsorption is made in the first 2-3 hours for untreated and heat treated wood. Modified wood adsorbs more chromium throughout the time. For all the samples, adsorption fitted relatively well the Langmuir model with correlation coefficient ranging from 0.85 to 0.97.

The research is connected with investigations of biomass application for production of bioproducts with higher added value. The most popular bioresource is wood, and therefore, the main question today is about future development and eco-design of products. The paper emphasizes and evaluates energy sector which is open for use of wood logs, wood chips, wood pellets and so on. The main aim for this research study was to build a framework to analyse development perspectives for wood pellet production. To reach the goal, a system dynamics model of energy wood supplies, processing, and consumption is built. Production capacity, energy consumption, changes in energy and technology efficiency, required labour source, prices of wood, energy and labour are taken into account. Validation and verification tests with available data and information have been carried out and indicate that the model constitutes the dynamic hypothesis. It is found that the more is invested into pellets production, the higher the specific profit per production unit compared to wood logs and wood chips. As a result, wood chips production is decreasing dramatically and is replaced by wood pellets. The limiting factor for pellet industry growth is availability of wood sources. This is governed by felling limit set by the government based on sustainable forestry principles. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bioenergy" title="bioenergy">bioenergy</a>, <a href="https://publications.waset.org/abstracts/search?q=biotechonomy" title=" biotechonomy"> biotechonomy</a>, <a href="https://publications.waset.org/abstracts/search?q=system%20dynamics%20modelling" title=" system dynamics modelling"> system dynamics modelling</a>, <a href="https://publications.waset.org/abstracts/search?q=wood%20pellets" title=" wood pellets"> wood pellets</a> </p> <a href="https://publications.waset.org/abstracts/56293/biotechonomy-system-dynamics-modelling-sustainability-of-pellet-production" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56293.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">410</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">1464</span> Wood Framing Roof Resistant Support for Hurricane</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=P.%20Hajyalikhani">P.

The typical roof framing for wood-framed buildings is sloped and consists of several structural members, such as rafters, hips, and valleys that link to the ridge and ceiling joists. The most common type of wood framing used is platform framing, also known as stick framing. Failures of the wood framing structures are among the most common types of wind damage in densely populated regions. Wood-framed buildings are under uplift during tornadoes and hurricanes which cause the failure in the roof. The bracing long structure members such as hip and valley have a large impact on the resilience of wood-framed buildings. As a result, the common failures in wood-framed buildings are reviewed, and the critical support locations for lengthy hips and valleys with various slopes are analyzed and recommended. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=rafters" title="rafters">rafters</a>, <a href="https://publications.waset.org/abstracts/search?q=hips" title=" hips"> hips</a>, <a href="https://publications.waset.org/abstracts/search?q=valleys" title=" valleys"> valleys</a>, <a href="https://publications.waset.org/abstracts/search?q=hip" title=" hip"> hip</a>, <a href="https://publications.waset.org/abstracts/search?q=ceiling%20joist" title=" ceiling joist"> ceiling joist</a>, <a href="https://publications.waset.org/abstracts/search?q=roof%20failures" title=" roof failures"> roof failures</a>, <a href="https://publications.waset.org/abstracts/search?q=residential%20and%20commercial%20structures" title=" residential and commercial structures"> residential and commercial structures</a>, <a href="https://publications.waset.org/abstracts/search?q=hurricane" title=" hurricane"> hurricane</a>, <a href="https://publications.waset.org/abstracts/search?q=tornadoes" title=" tornadoes"> tornadoes</a>, <a href="https://publications.waset.org/abstracts/search?q=building%20codes" title=" building codes"> building codes</a> </p> <a href="https://publications.waset.org/abstracts/183819/wood-framing-roof-resistant-support-for-hurricane" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/183819.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">67</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">1463</span> Olive Seed Tannins as Bioadhesives for Manufacturing Wood-Based Panels</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ajith%20K.%20A.%20Gedara">Ajith K.

Biuret test and ferric chloride test revealed that water or alkali NaOH extractions of olive seed flour are rich in proteins and tannins. Both protein and tannins are well-known bio-based wood adhesives in the wood-based panel industry. In general, tannins-based adhesives show better mechanical and physical properties than protein wood adhesives. This paper explores different methods of extracting tannins from olive seed flour against the tannins yield and their applications as bio-based adhesives in wood-based panels. Once investigated, the physical and the mechanical properties of wood-based panels made using bio-adhesives based tannins extracted from olive seed flour revealed that the resulting products seemed to satisfy the Japanese Industrial Standards JIS A 5908:2015. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bio-adhesives" title="bio-adhesives">bio-adhesives</a>, <a href="https://publications.waset.org/abstracts/search?q=olive%20seed%20flour" title=" olive seed flour"> olive seed flour</a>, <a href="https://publications.waset.org/abstracts/search?q=tannins" title=" tannins"> tannins</a>, <a href="https://publications.waset.org/abstracts/search?q=wood-based%20panels" title=" wood-based panels"> wood-based panels</a> </p> <a href="https://publications.waset.org/abstracts/137443/olive-seed-tannins-as-bioadhesives-for-manufacturing-wood-based-panels" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/137443.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">151</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">1462</span> Constraints and Opportunities of Wood Production Value Chain: Evidence from Southwest Ethiopia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abduselam%20Faris">Abduselam Faris</a>, <a href="https://publications.waset.org/abstracts/search?q=Rijalu%20Negash"> Rijalu Negash</a>, <a href="https://publications.waset.org/abstracts/search?q=Zera%20Kedir"> Zera Kedir</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study was initiated to identify constraints and opportunities of the wood production value chain in Southwest Ethiopia. About 385 wood trees growing farmers were randomly interviewed. Similarly, about 30 small-scale wood processors, 30 retailers, 15 local collectors and 5 wholesalers were purposively included in the study. The results of the study indicated that 98.96 % of the smallholder farmers that engaged in the production of wood trees which is used for wood were male-headed, with an average age of 46.88 years. The main activity that the household engaged was agriculture (crop and livestock) which accounts for about 61.56% of the sample respondents. Through value chain mapping of actors, the major value chain participant and supporting actors were identified. On average, the tree-growing farmers generated gross income of 9385.926 Ethiopian birr during the survey year. Among the critical constraints identified along the wood production value chain was limited supply of credit, poor market information dissemination, high interference of brokers, and shortage of machines, inadequate working area and electricity. The availability of forest resources is the leading opportunity in the wood production value chain. Reinforcing the linkage among wood production value chain actors, providing skill training for small-scale processors, and developing suitable policy for wood tree wise use is key recommendations forward. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=value%20chain%20analysis" title="value chain analysis">value chain analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=wood%20production" title=" wood production"> wood production</a>, <a href="https://publications.waset.org/abstracts/search?q=southwest%20Ethiopia" title=" southwest Ethiopia"> southwest Ethiopia</a>, <a href="https://publications.waset.org/abstracts/search?q=constraints%20and%20opportunities" title=" constraints and opportunities"> constraints and opportunities</a> </p> <a href="https://publications.waset.org/abstracts/150339/constraints-and-opportunities-of-wood-production-value-chain-evidence-from-southwest-ethiopia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/150339.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">94</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">1461</span> Analysis of Green Wood Preservation Chemicals</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aitor%20Barbero-L%C3%B3pez">Aitor Barbero-López</a>, <a href="https://publications.waset.org/abstracts/search?q=Soumaya%20Chibily"> Soumaya Chibily</a>, <a href="https://publications.waset.org/abstracts/search?q=Gerhard%20Scheepers"> Gerhard Scheepers</a>, <a href="https://publications.waset.org/abstracts/search?q=Thomas%20Grahn"> Thomas Grahn</a>, <a href="https://publications.waset.org/abstracts/search?q=Martti%20Ven%C3%A4l%C3%A4inen"> Martti Venäläinen</a>, <a href="https://publications.waset.org/abstracts/search?q=Antti%20Haapala"> Antti Haapala</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Wood decay is addressed continuously within the wood industry through use and development of wood preservatives. The increasing awareness on the negative effects of many chemicals towards the environment is causing political restrictions in their use and creating more urgent need for research on green alternatives. This paper discusses some of the possible natural extracts for wood preserving applications and compares the analytical methods available for testing their behavior and efficiency against decay fungi. The results indicate that natural extracts have interesting chemical constituents that delay fungal growth but vary in efficiency depending on the chemical concentration and substrate used. Results also suggest that presence and redistribution of preservatives in wood during exposure trials can be assessed by spectral imaging methods although standardized methods are not available. This study concludes that, in addition to the many standard methods available, there is a need to develop new faster methods for screening potential preservative formulation while maintaining the comparability and relevance of results. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=analytics" title="analytics">analytics</a>, <a href="https://publications.waset.org/abstracts/search?q=methods" title=" methods"> methods</a>, <a href="https://publications.waset.org/abstracts/search?q=preservatives" title=" preservatives"> preservatives</a>, <a href="https://publications.waset.org/abstracts/search?q=wood%20decay" title=" wood decay"> wood decay</a> </p> <a href="https://publications.waset.org/abstracts/85085/analysis-of-green-wood-preservation-chemicals" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85085.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">232</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">1460</span> The Effects of Wood Ash on Ignition Point of Wood</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=K.%20A.%20Ibe">K.

The ash and moisture contents of the wood saw dust from Mahogany (Khaya ivorensis), Opepe (Sarcocephalus latifolius), Abura (Hallealedermannii verdc), Rubber (Heavea brasilensis) and Poroporo (Sorghum bicolour) were determined using a furnace (Vecstar furnaces, model ECF2, serial no. f3077) and oven (Genlab laboratory oven, model MINO/040) respectively. The metal contents of the five wood sawdust ash samples were determined using a Perkin Elmer optima 3000 dv atomic absorption spectrometer while the ignition points were determined using Vecstar furnaces model ECF2. Poroporo had the highest ash content, 2.263 g while rubber had the least, 0.710 g. The results for the moisture content range from 2.971 g to 0.903 g. Magnesium metal had the highest concentration of all the metals, in all the wood ash samples; with mahogany ash having the highest concentration, 9.196 ppm while rubber ash had the least concentration of magnesium metal, 2.196 ppm. The ignition point results showed that the wood ashes from mahogany and opepe increased the ignition points of the test wood samples when coated on them while the ashes from poroporo, rubber and abura decreased the ignition points of the test wood samples when coated on them. However, Opepe saw dust ash decreased the ignition point in one of the test wood samples, suggesting that the metal content of the test wood sample was more than that of the Opepe saw dust ash. Therefore, Mahogany and Opepe saw dust ashes could be used in the surface treatment of wood to enhance their fire resistance or retardancy. However, the caution to be exercised in this application is that the metal content of the test wood samples should be evaluated as well. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ash" title="ash">ash</a>, <a href="https://publications.waset.org/abstracts/search?q=fire" title=" fire"> fire</a>, <a href="https://publications.waset.org/abstracts/search?q=ignition%20point" title=" ignition point"> ignition point</a>, <a href="https://publications.waset.org/abstracts/search?q=retardant" title=" retardant"> retardant</a>, <a href="https://publications.waset.org/abstracts/search?q=wood%20saw%20dust" title=" wood saw dust"> wood saw dust</a> </p> <a href="https://publications.waset.org/abstracts/29316/the-effects-of-wood-ash-on-ignition-point-of-wood" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29316.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">389</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">1459</span> Ion Beam Sputtering Deposition of Inorganic-Fluoropolymer Nano-Coatings for Real-Life Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Valentini">M.

Research and technology are constantly involved to develop advanced finishing which can provide bacteriostatic growth without compromising the other typical properties of a textile as durability and non-toxicity, just to cite a few. Here we report on the antimicrobial coatings obtained, at room temperature and without the use of solvents, by means of the ion beam co-sputtering technique of an Ag target and a polytetrafluoroethylene one. In particular, such method allows to conjugate the well-known antimicrobial action of silver with the anti-stain and water-repellent properties of the fluoropolymer. Moreover, different Ag nanoparticle loadings (φ) were prepared by tuning the material deposition conditions achieving a fine control on film thickness and their antimicrobial/anti-stain properties. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antimicrobial" title="antimicrobial">antimicrobial</a>, <a href="https://publications.waset.org/abstracts/search?q=ion%20beam%20sputtering" title=" ion beam sputtering"> ion beam sputtering</a>, <a href="https://publications.waset.org/abstracts/search?q=nanocoatings" title=" nanocoatings"> nanocoatings</a>, <a href="https://publications.waset.org/abstracts/search?q=anti-stain" title=" anti-stain"> anti-stain</a> </p> <a href="https://publications.waset.org/abstracts/6457/ion-beam-sputtering-deposition-of-inorganic-fluoropolymer-nano-coatings-for-real-life-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/6457.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">392</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">1458</span> Evaluation of Anti-Cancer Activities of Formononetin in Lung Cancer by in vitro Methods</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vishnu%20Varthan%20Vaithiyalingam%20Jagannathan">Vishnu Varthan Vaithiyalingam Jagannathan</a>, <a href="https://publications.waset.org/abstracts/search?q=Lakshmi%20Karunanidhi%20Santhanalakshmi"> Lakshmi Karunanidhi Santhanalakshmi</a>, <a href="https://publications.waset.org/abstracts/search?q=Srividya%20Ammayappan%20Rajam"> Srividya Ammayappan Rajam</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Formononetin is the O-Methoxy Flavonol that has many pharmacological activities, which belongs to the flavonoid family.

The specific detection of the pyrethroid insecticide is currently obtained after extraction followed by chemical analysis by chromatography techniques. However visualizing the insecticide molecule within the wood structure requires specific probes together with microscopy techniques. Therefore, the aim of the present work was to apply a new methodology based on antibody-antigen recognition and electronic microscopy to visualize directly pyrethroids in the wood material. A polyclonal antibody directed against cypermethrin was developed and implement it on Pinus sylvestris wood samples coated with technical cypermethrin. The antibody was tested on impregnated wood and the specific recognition of the insecticide was visualized in transmission electron microscopy (TEM). The immunogold-TEM assay evidenced the capacity of the synthetic biocide to penetrate in the wood. The depth of penetration was measured on sections taken at increasing distances from the coated surface of the wood. Such results correlated with chemical analyzes carried out by GC-ECD after extraction. In addition, the immuno-TEM investigation allowed visualizing, for the first time at the ultrastructure scale of resolution, that cypermethrin was able to diffuse within the secondary wood cell walls. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cypermethrin" title="cypermethrin">cypermethrin</a>, <a href="https://publications.waset.org/abstracts/search?q=insecticide" title=" insecticide"> insecticide</a>, <a href="https://publications.waset.org/abstracts/search?q=wood%20penetration" title=" wood penetration"> wood penetration</a>, <a href="https://publications.waset.org/abstracts/search?q=wood%20retention" title=" wood retention"> wood retention</a>, <a href="https://publications.waset.org/abstracts/search?q=immuno-transmission%20electron%20microscopy" title=" immuno-transmission electron microscopy"> immuno-transmission electron microscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=polyclonal%20antibody" title=" polyclonal antibody"> polyclonal antibody</a> </p> <a href="https://publications.waset.org/abstracts/36690/development-of-a-new-characterization-method-to-analyse-cypermethrin-penetration-in-wood-material-by-immunolabelling" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36690.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">413</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">1456</span> Kinetic Analysis of Wood Pellets by Isothermal Calorimetry for Evaluating its Self-heating Potential</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Can%20Yao">Can Yao</a>, <a href="https://publications.waset.org/abstracts/search?q=Chang%20Dong%20Sheng"> Chang Dong Sheng</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The heat released by wood pellets during storage will cause self-heating and even self-ignition. In this work, the heat release rates of pine, fir wood and mahogany pellets at 30–70℃ were measured by TAM air isothermal calorimeter, and the kinetic analysis was performed by iso-conversion ratio and non-steady-state methods to evaluate its self-heating potential. The results show that the reaction temperature can significantly affect the heat release rate. The higher the temperature, the greater the heat release rate. The heat release rates of different kinds of wood pellets are obviously different, and the order of the heat release rates for the three pellets at 70℃ is pine > fir wood > mahogany. The kinetic analysis of the iso-conversion ratio method indicates that the distribution of activation energy for pine, fir wood and mahogany pellets under the release of 0.1–1.0 J/g specific heat are 58–102 kJ/mol, 59–108 kJ/mol and 59–112 kJ/mol, respectively. Their activation energies obtained from the non-steady-state kinetic analysis are 13.43 kJ/mol, 19.19 kJ/mol and 21.09 kJ/mol, respectively.

Manufacturers of wood products and furniture usually generate sawdust and pieces of side-cuts. These are produced by cutting, drilling, and milling operations as well. Three different percentages of substitution of quartz sand were tried: 2.5%, 5%, and 10% by volume. Wood by-products were pre-soaked in calcium hydroxide aqueous solution in order to obtain wood mineralization to avoid undesirable effects on the bio-based building materials. Bio-based mortars were characterized by means of compression and bending tests, free drying shrinkage tests, resistance to water vapour permeability, water capillary absorption, and, finally, thermal conductivity measurements. Results obtained showed that a maximum dosage of 5% wood by-products should be used in order to avoid an excessive loss of bio-based mortar mechanical strength. On the other hand, by adding the proper dosage of water-reducing admixture, adequate mechanical performance can be achieved even with 10% wood waste addition. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bio-based%20mortar" title="bio-based mortar">bio-based mortar</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20efficiency" title=" energy efficiency"> energy efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=lightweight%20mortar" title=" lightweight mortar"> lightweight mortar</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20insulation" title=" thermal insulation"> thermal insulation</a>, <a href="https://publications.waset.org/abstracts/search?q=wood%20waste" title=" wood waste"> wood waste</a> </p> <a href="https://publications.waset.org/abstracts/194886/optimization-of-bio-based-lightweight-mortars-containing-wood-waste" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/194886.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">5</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">1454</span> Fracture Properties Investigation of Artocarpus odoratissimus Composite with Polypropylene (PP)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Kamal%20M.%20Shah">M.

The purpose of this project is to investigate the fracture properties of Artocarpus odoratissimus composite with PP. The WPC were manufactured by hot-press technique with varying formulations which are 10:0 (100% pure PP), 50:50 (40 g of wood fiber and 40 g of PP) and 60:40 (48 g of wood fiber and 32 g of PP). The mechanical properties were investigated. Tensile and flexural were carried out according to ASTM D 638 and ASTM D 790. The results were analysed to calculate the tensile strength. Tensile strength at break is ranged from 13.2 N/mm2 to 21.7 N/mm2 while, the flexural strength obtained is varying from 14.7 N/mm2 to 31.1 N/mm2. The results of the experiment showed that tensile and flexural properties of the composite were increased with the adding of wood fiber material. Finally, the Scanning Electron Microscope (SEM), have been done to study the fracture behavior of the WPC specimens. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Artocarpus%20odoratissimus" title="Artocarpus odoratissimus">Artocarpus odoratissimus</a>, <a href="https://publications.waset.org/abstracts/search?q=polypropylene%20thermoplastic" title=" polypropylene thermoplastic"> polypropylene thermoplastic</a>, <a href="https://publications.waset.org/abstracts/search?q=wood%20fiber" title=" wood fiber"> wood fiber</a>, <a href="https://publications.waset.org/abstracts/search?q=WPC" title=" WPC"> WPC</a> </p> <a href="https://publications.waset.org/abstracts/54481/fracture-properties-investigation-of-artocarpus-odoratissimus-composite-with-polypropylene-pp" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/54481.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">400</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">1453</span> Wood Energy in Bangladesh: An Overview of Status, Challenges and Development</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Md.%20Kamrul%20Hassan">Md.

The last portion of the national population of this country depends on wood energy for their daily primary energy need. This paper deals with the estimation of wood fuel at the current level and identifies the challenges and strategies related to the development of this resource. Desk research, interactive research and field survey were conducted for gathering and analyzing of data for this study. The study revealed that wood fuel plays a significant role in total primary energy supply in Bangladesh, and the contribution of wood fuel in final energy consumption in 2013 was about 24%. Trees on homestead areas, secondary plantation on off forest lands, and forests are the main sources of supplying wood fuel in the country. Insufficient supply of wood fuel against high upward demand is the main cause of concern for sustainable consumption, which eventually leads deterioration and depletion of the resources. Inadequate afforestation programme, lack of initiatives towards the utilization of set-aside lands for wood energy plantations, and inefficient management of the existing resources have been identified as the major impediments to the development of wood energy in Bangladesh. The study argued that enhancement of public-private-partnership afforestation programmes, intensifying the waste and marginal lands with short-rotation tree species, and formulation of biomass-based rural energy strategies at the regional level are relevant to the promotion of sustainable wood energy in the country. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bangladesh" title="Bangladesh">Bangladesh</a>, <a href="https://publications.waset.org/abstracts/search?q=challenge" title=" challenge"> challenge</a>, <a href="https://publications.waset.org/abstracts/search?q=supply" title=" supply"> supply</a>, <a href="https://publications.waset.org/abstracts/search?q=wood%20energy" title=" wood energy"> wood energy</a> </p> <a href="https://publications.waset.org/abstracts/47360/wood-energy-in-bangladesh-an-overview-of-status-challenges-and-development" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/47360.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">188</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">1452</span> Performance Tests of Wood Glues on Different Wood Species Used in Wood Workshops: Morogoro Tanzania</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Japhet%20N.%20Mwambusi">Japhet N. Mwambusi </a> </p> <p class="card-text"><strong>Abstract:</strong></p> High tropical forests deforestation for solid wood furniture industry is among of climate change contributing agents. This pressure indirectly is caused by furniture joints failure due to poor gluing technology based on improper use of different glues to different wood species which lead to low quality and weak wood-glue joints. This study was carried in order to run performance tests of wood glues on different wood species used in wood workshops: Morogoro Tanzania whereby three popular wood species of <em>C. lusitanica, T. glandis</em> and <em>E. maidenii</em> were tested against five glues of Woodfix, Bullbond, Ponal, Fevicol and Coral found in the market. The findings were necessary on developing a guideline for proper glue selection for a particular wood species joining. Random sampling was employed to interview carpenters while conducting a survey on the background of carpenters like their education level and to determine factors that influence their glues choice. Monsanto Tensiometer was used to determine bonding strength of identified wood glues to different wood species in use under British Standard of testing wood shear strength (BS EN 205) procedures. Data obtained from interviewing carpenters were analyzed through Statistical Package of Social Science software (SPSS) to allow the comparison of different data while laboratory data were compiled, related and compared by the use of MS Excel worksheet software as well as Analysis of Variance (ANOVA). Results revealed that among all five wood glues tested in the laboratory to three different wood species, Coral performed much better with the average shear strength 4.18 N/mm<sup>2</sup>, 3.23 N/mm<sup>2</sup> and 5.42 N/mm<sup>2</sup> for Cypress, Teak and Eucalyptus respectively. This displays that for a strong joint to be formed to all tree wood species for soft wood and hard wood, Coral has a first priority in use. The developed table of guideline from this research can be useful to carpenters on proper glue selection to a particular wood species so as to meet glue-bond strength. This will secure furniture market as well as reduce pressure to the forests for furniture production because of the strong existing furniture due to their strong joints. Indeed, this can be a good strategy on reducing climate change speed in tropics which result from high deforestation of trees for furniture production. <p class="card-text"><strong>Keywords:</strong>
