Research ArticleOpen accessIn the abstractProduction of Biodiesel by Enzymatic Transesterification: ReviewA.E. Ghaly, D. Dave, M.S. Brooks, S. BudgeProblem Statement: The research on the production of biodiesel has increased significantly in recent years because of the need for an alternative fuel which endows with biodegradability, low toxicity and renewability. Plant oils, animal fats, microalgal oils and waste products such as animal rendering, fish processing waste and cooking oils have been employed as feedstocks for biodiesel production. In order … …American Journal of Biochemistry and Biotechnology, Vol. 6, Issue 2 · 30 Jun 2010 · 21,478 accessesView PDF Cite

Research ArticleOpen accessIn the abstractPotential, Implications and Solutions Regarding the Use of Rendered Animal Fats in AquafeedsJesse T. Trushenski, Rebecca T. LochmannProblem statement: In the past, aquafeeds were comprised largely of fish meal and fish oil derived from marine reduction fisheries. In addition to being highly palatable and readily digested by cultured fishes, these feedstuffs were historically inexpensive sources of protein, energy and essential nutrients. However, increasing cost and concerns over safety and sustainability have greatly incentivized the transition from fish … …American Journal of Animal and Veterinary Sciences, Vol. 4, Issue 4 · 31 Dec 2009 · 14,003 accessesView PDF Cite

Research ArticleOpen accessIn the abstractFeatures Resistance of Sugar Sorgo (Sorghum Saccharatum (L) Pers.) Varieties to Environmental Stress FactorsMukasheva Danagul, Kirshibayev Yerlan Ahmetkalievich, Baiseitova Gulnaz et al.One of the types of sorghum, the most drought-resistant crop in the world, sugar sorghum (Sorghum Saccharum) is characterized by the fact that, unlike grain and broom sorghum, its stem juice contains more than 10-20% sugars. Because it can be cultivated in the arid southern regions, where it is either unprofitable or impossible to grow sugar beets, the interest in … …OnLine Journal of Biological Sciences, Vol. 22, Issue 1 · 5 Feb 2022 · 6,386 accessesView PDF Cite

Research ArticleOpen accessIn the abstractKinematics and Forces to a New Model Forging ManipulatorRaffaella Aversa, Relly Victoria V. Petrescu, Bilal Akash et al.Forging manipulators have become more prevalent in the industry of today. They are used to manipulate objects to be forged. The most common forging manipulators move on a railway to have a better precision and stability. Heavy payload forging manipulators systems are normally characterized by a large load output and a large capacitive load input as well. The relationship between … …American Journal of Applied Sciences, Vol. 14, Issue 1 · 3 Jan 2017 · 8,173 accessesView PDF Cite

Research ArticleOpen accessIn the abstractThe Effects of Oil Film Shape on Piston Ring and Liner Tribology Under Mixed LubricationAbbas Razavykia, Cristiana Delprete, Eugenio Brusa, Yaser HosseiniMechanical power loss reduction at lubricated reciprocating and rotating components is recognized as an approach to improve the efficiency and to reduce the emissions of Internal Combustion Engines (ICEs). To achieve these goals, the instantaneous investigation of lubrication characteristics is required. Piston ring pack is of paramount importance as it is known as major contributor to frictional losses and energy … …American Journal of Engineering and Applied Sciences, Vol. 14, Issue 4 · 10 Nov 2021 · 6,533 accessesView PDF Cite

Research ArticleOpen accessIn the abstractOn the Design and Construction of a Dual Axis Solar Tracker Prototype for a Dish Concentrator using ATMega3298P MicrocontrollerAlbright Abu Edet, Samaila Umaru, Isah IbrahimThe desire for reliable power supply is the reason for further research into alternative sources of power. Although solar tracking is not a new technology, yet solar harvesters still suffer low efficiency due to the intermittence of solar insolation. Thus many smart systems have been designed to maximise solar harvesters. Among the systems is the dual axis solar tracking system. … …Journal of Mechatronics and Robotics, Vol. 5, Issue 1 · 21 Apr 2021 · 7,253 accessesView PDF Cite
