Research ArticleOpen accessIn the keywordsSynthesis of Feather Concentrate from Broiler Feather Waste using Different Chemical Hydrolysis Process and Effect on Its PropertiesMuhammad Irfan Said, Effendi Abustam, Wempie Pakiding et al.Feather waste, a resultant of livestock industry, has annually increased, but its existence has not been optimally utilized. Production of feather concentrate (Fc) is regarded a beneficial application to minimze the waste. The objective of the study was to evaluate the use of NaOH and HCl as a hydrolyzing agent in Fc preparation. The results showed that microstructural changes occurred … …OnLine Journal of Biological Sciences, Vol. 18, Issue 3 · 25 Jan 2018 · 7,542 accessesView PDF Cite

Research ArticleOpen accessIn the abstractOptimized Biodiesel Production from jatropha curcas oilHaruna Musa, Daniel Eric, Alkhairu Hassan et al.In this study, a mathematical model for the trans-esterification reaction of jatropha curcas seed Oil (JCO) was developed using Response Surface Methodology(RSM) in terms of operational variables such as temperature (50 to 80°C), catalyst concentration (0.7 to 1% in relation to oil mass) and methanol/oil ratio (3:1-9:1), at fixed reaction time (90 min) and mixing intensity. Biodiesel was produced by … …Energy Research Journal, Vol. 12, Issue 1 · 12 Oct 2021 · 7,286 accessesView PDF Cite

Research ArticleOpen accessIn the abstractYeast Immobilization on Peanut Hulls for Potential Application in Beer FermentationWaldir D. Estela-Escalante, Sergio Rosales-Mendoza, Mario Moscosa-SantillánThe potential of using peanut hulls as support material for immobilization of yeast cells during beer fermentation was evaluated. After treatment of peanut hulls with 0.5% (w/v) NaOH, FTIR analysis revealed an important change on its chemical composition. For instance, the proportion of lignin decreased and as a result the adsorption of yeast cells onto the support material during fermentation … …American Journal of Biochemistry and Biotechnology, Vol. 15, Issue 3 · 22 Jul 2019 · 8,375 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAnalytical Method Validation of Vilazodone with Spectrofluorimetric Detection in Rabbit PlasmaIrene Sartini, Marco Salvadori, Beata Łebkowska-Wieruszewska et al.Vilazodone (VLZ) is an antidepressant agent approved in 2011 by Food and Drug Administration (FDA) for the treatment of major depressive syndromes. Its chemical structure derives from trazodone which is used as an off-label drug for dogs and cats in order to induce sedation and reduce anxiety, behavioural and pre-and post-operative stress. VLZ could be a potentially useful compound in … …American Journal of Animal and Veterinary Sciences, Vol. 14, Issue 1 · 2 Apr 2019 · 7,740 accessesView PDF Cite

Research ArticleOpen accessIn the abstractOptimization of Conditions for Extraction of Pepsin-Soluble Collagen from Indonesian Local “Kacang” Goatskin by Response Surface MethodologyRina Wahyuningsih, Rusman, Nurliyani et al.Indonesian local “Kacang” goat is an animal species widely known by consumers over the world which possesses many health effects. Goatskin is one of body parts which has potential as collagen sources. The optimal conditions for collagen extraction were determined by response surface methodology in this study. Multiple response optimization designs were applied to evaluate the effects of two independent … …American Journal of Animal and Veterinary Sciences, Vol. 13, Issue 2 · 12 May 2018 · 8,105 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEffects of Different Environments on Reinforcement Concrete CorrosionMohammed Thalji Awwad, Omar Asad AhmadThis research focuses on various forms of steel bar corrosion located in different environments and the factors affecting the corrosion process, both the external (surrounding environment around concrete elements) and the internal environment (concrete itself), as well as on the investigations and tests for this type of damage, in order to develop measurements and recommendations that will reduce harmful investment … …American Journal of Environmental Sciences, Vol. 13, Issue 4 · 15 Sep 2017 · 7,805 accessesView PDF Cite

Research ArticleOpen accessIn the abstractOptimization of Biodiesel Production from Spent Palm Cooking Oil Using Fractional Factorial Design Combined with the Response Surface MethodologyS.M. Zakir Hossain, Nahid Sultana, Muhammad Faisal Irfan et al.Fractional Factorial Design (FFD) of the experiments combined with the response surface methodology was used to determine the optimum conditions for the production of biodiesel from Used Cooking Oil (UCO) in a batch reactor. Spent palm olein cooking oil was used as a raw material for biodiesel production as it is commonly used in most of the restaurants in Bahrain. … …American Journal of Applied Sciences, Vol. 13, Issue 11 · 22 Nov 2016 · 8,443 accessesView PDF Cite

Research ArticleOpen accessIn the abstractCarbon Dioxide Utilization for an Enhanced Biohydrogen Production of a Biomass HydrolysateAlma Negre Abug, Young Sook OhBio-hydrogen (H2) production in a thermophilic anaerobic bioreactor with carbon dioxide (CO2) utilization at the headspace was investigated at different ratio of Biomass substrate to Microorganism (B/M). A 3 mL volume of 80% NaOH (m/v) solution was continuously hung at the headspace of the bioreactors to capture carbon dioxide. The utilization of CO2 at its headspace, proved to enhance bio … …American Journal of Environmental Sciences, Vol. 12, Issue 4 · 9 Aug 2016 · 7,229 accessesView PDF Cite
