Research ArticleOpen accessIn the abstractExtraction Optimization of Essential Oil from Medicago hispida and Preliminary Inhibitory Mechanism Against Escherichia coliXiulan Chu, Qianfeng Chen, Tong Wang et al.In this study, the extraction optimization, characterization, antioxidant evaluation and preliminary inhibitory mechanism against Escherichia coli of the essential oil from dried Medicago hispida (EOMH) were explored to uncover the pending questions that had been raised in our previous work and to enlarge the industrial potential of EOMH production. The optimal parameters for EOMH extraction were: Extraction time of 7 … …American Journal of Biochemistry and Biotechnology, Vol. 17, Issue 4 · 20 Nov 2021 · 5,791 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 abstractSupplementation of Prill Fat Derived from Palm Oil on Nutrient Digestibility and Dairy Cow PerformanceLolita Udin Riestanti, Despal, Yuli RetnaniPrill fat is a hydrogenated vegetable oil which contains more than 85% palmitic acid with a high melting point. Due to this reason, it does not melt at rumen temperature and bypass rumen degradation. This study was aimed to determine the optimum level of prill fat (86% palmitic acid) supplementation in dairy ration on fermentation characteristics, feed digestibility, milk production, … …American Journal of Animal and Veterinary Sciences, Vol. 16, Issue 2 · 1 Jul 2021 · 8,756 accessesView PDF Cite

Research ArticleOpen accessIn the abstractPalm Oil Sludge Fermentation with Pleurotus ostreatus and its Application in Laying Quails' RationAde Trisna, Nuraini, Yoze Rizal, MirzahPalm oil sludge is a byproduct of palm oil processing which is still limited in its use as a constituent of poultry feed. This study aims to improve the quality of palm sludge fermented with Pleurotus ostreatus and to determine its effect on the production of laying quail. The study was divided into 2 stages of research. Phase 1 of … …American Journal of Animal and Veterinary Sciences, Vol. 15, Issue 4 · 9 Dec 2020 · 7,634 accessesView PDF Cite

Research ArticleOpen accessIn the abstractNovel De-Oiling of Oil-WaterEmmanuel Ewa Ekeng, Jonah Chukwuemeka AgunwambaThe study anchors on developing a mechanistic model for oil-water separation. Over the years, researchers have been working on how to improve the quality of produced water effluent especially from oil and gas operations sent to the receiving waters. Despite the standard set for compliance by regulatory bodies like united nation agency, ministry, departments and other agencies both state and … …American Journal of Applied Sciences, Vol. 17, Issue 1 · 2 Sep 2020 · 6,952 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEffects of Palm Kernel Cake Based Biosupplement Biscuits on Nutrient Utilization, Growth Performance, and Metabolic Responses in Male Ettawah GoatsTintin Rostini, Suharlina, Achmad Jaelani et al.Palm Kernel Cake (PKC), a major by-product of the palm oil industry, has considerable potential as an alternative feed ingredient for ruminants because of its wide availability, moderate protein content, and economic value. However, its utilization is often constrained by high fiber and lignocellulosic components that may limit nutrient digestibility. This study evaluated the effects of PKC-based biosupplement biscuits as … …American Journal of Animal and Veterinary Sciences, Vol. 21, Issue 3 · 22 Oct 2026 · 390 accessesView PDF Cite

Research ArticleOpen accessIn the abstractUltrastructural and Circadian Morphometric Characteristics of Rat Pinealocytes Under Physiological and Toxic ConditionsAnna I. Anurkina, David A. Areshidze, Maria A. Kozlova, Valery P. ChernikovCarbon tetrachloride (CCl₄) exhibits pronounced neurotoxic effects following acute or chronic exposure. Recent studies indicate that the pineal gland responds to CCl₄ intoxication by altering its secretory function, although detailed ultrastructural changes in pinealocytes remain inadequately investigated. This research addresses the urgent need to elucidate the mechanisms of CCl₄ toxicity on the pineal gland, which could contribute to developing strategies … …OnLine Journal of Biological Sciences, Vol. 26, Issue 2 · 1 Jun 2026 · 1,174 accessesView PDF Cite

Research ArticleOpen accessIn the abstractLong Term Ageing Effect on Physical and Shear Strength Characteristics of Oil Contaminated Sandy Soils of Al-Ahmadi Field in KuwaitHumoud Melfi Aldaihani, Fahad A. Al-OtaibiSerious environmental damage was caused to Kuwait when more than 600 oil wells were set alight following the 1991 Gulf War, leading to hydrocarbon contamination and a series of ‘oil lakes’ being created in the desert. The effects of these highly damaging actions are still detectable today, 27 years later. The main contribution of this paper is that the effects … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 1 · 1 Apr 2019 · 8,065 accessesView PDF Cite

The World Health Organization (WHO) reports that about 350 million people are considered to be at risk of contracting leishmaniasis especially among people living in the developing countries. This research will be the first time that evaluate antileishmanial activity of essential oils of A. … …OnLine Journal of Biological Sciences, Vol. 19, Issue 1 · 2 Mar 2019 · 9,202 accessesView PDF Cite

Research ArticleOpen accessIn the abstractGrain Size Distribution Characteristics Variation in Oily Contaminated Sandy Soils Due to Long Term Aging Effect in Al-Ahmadi Field at KuwaitHumoud Melfi Aldaihani, Fahad A. Alotaibi, Farraj F. Al-ajmiAlmost three decades on, the negative environmental impacts arising from the burning of over 600 oil wells in Kuwait following the 1991 Gulf War are still evident. At the time of the incident, the Kuwaiti desert region became polluted with hydrocarbon, with a number of ‘oil lakes’ forming, causing critical harm to local land. This paper discusses the shifts in … …American Journal of Applied Sciences, Vol. 15, Issue 10 · 23 Nov 2018 · 8,412 accessesView PDF Cite
