Literature ReviewOpen accessIn the abstractExtraction Performance of Essential Oils by Hydrodistillation Using Mathematical Models: A Systematic ReviewLenin Quiñones Huatangari, Frank Fernandez Rosillo, Eliana Milagros Cabrejos Barrios et al.Essential oils are complex mixtures of volatile organic compounds valued for their antimicrobial and antioxidant properties, with widespread applications in the food, pharmaceutical, and cosmetic industries. Among the various extraction techniques employed, hydrodistillation remains one of the most widely used methods. The extraction yield of essential oils by hydrodistillation is influenced by multiple factors, and quantifying these through mathematical modelling … …OnLine Journal of Biological Sciences, Vol. 26, Issue 1 · 25 Mar 2026 · 2,508 accessesView PDFCite
Research ArticleOpen accessIn the abstractEfficacy of Murraya paniculata Leaf Flour in Reducing Subclinical Mastitis in Dairy Goats Fed Date Pulp-Based DietsDwierra Evvyernie, Endah Yuniarti, Rika Zahera, Anuraga JayanegaraSubclinical mastitis is a major concern in dairy production, leading to economic losses and antibiotic dependence, which poses risks of milk residue contamination. As a natural alternative, orange jasmine (Murraya paniculata) leaves, rich in flavonoids, exhibit antimicrobial and anti-inflammatory properties. This study investigated the effects of incorporating date pulp and orange jasmine leaf flour (OLF) into the diets of lactating … …American Journal of Animal and Veterinary Sciences, Vol. 20, Issue 4 · 21 Feb 2026 · 1,590 accessesView PDFCite
Research ArticleOpen accessIn the abstractDevelopment of an Arduino-Based Robotic Arm Yam Heap MakerAgbese Raphael, Dagwa Ishaya Musa, Nurudeen Abdulhakeem Hassan, Adekunle JoshuaIn this study, a prototyperobotic arm yam heap-maker using Arduino was developed. Nigeria produces around75% of global yam production which is widely consumed as staple foods in Africaand Asia and as raw materials for processing into other finished goods. Theproduction of this economic commodity is largely crude and labor-intensive assuch the need to adopt a modern approach to farming. The … …Journal of Mechatronics and Robotics, Vol. 6, Issue 1 · 2 Sep 2022 · 6,463 accessesView PDFCite
Research ArticleOpen accessIn the abstractDoes Monetary Policy Stimulates Macroeconomic Performance during Economic Downturn in Nigeria?Bashir Adelowo Wahab, Sam-Siso Ebasi OkrinyaThis study investigated the relationship between monetary policy and macroeconomic performance in Nigeria during 1981-2018. The stochastic properties of the time series data were examined using both conventional and unit root tests with structural breaks to account for shift dummy in the series. Their results indicates that the series are combination of both I(0) and I(1) in the same specification … …Journal of Social Sciences, Vol. 16, Issue 1 · 11 Feb 2020 · 8,269 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Leucaena leucocephala Protein Supplement on Nutrient Intake, Milk Yield and Quality, Hematology, Metabolites and Economy Efficiency in Etawah Crossbreed GoatsIdat Galih Permana, Salwa Iffat Zahidah Arif, Fajar Rezki Pambudi et al.Legumes, such as Leucaena leucocephala (LL), have high protein and Rumen degradable Protein (RUP) content, so adding legumes to the diet of dairy goats can meet the protein requirements for milk synthesis. However, the addition of LL alone is insufficient to meet the RUP requirement of dairy goats, thus requiring other protein sources. LL Protein Supplement (LLPS) is a feed … …American Journal of Animal and Veterinary Sciences, Vol. 20, Issue 2 · 23 Aug 2025 · 5,345 accessesView PDFCite
