Research ArticleOpen accessIn the keywordsComparative Analysis of Laboratory Measured and PVTP Software DataOluwasanmi Samuel Teniola, Mercy Isaiah OkegbemiCubic Equations of State (EOS), including the Peng-Robinson (PR) and Soave-Redlich-Kwong (SRK) models, are foundational in petroleum engineering for modeling the thermodynamic behavior of hydrocarbon systems. These EOS are widely used to predict phase behavior and Pressure-Volume-Temperature (PVT) properties, which are crucial for reservoir simulation, production forecasting, and enhanced oil recovery. However, their predictive accuracy diminishes when applied to complex … …American Journal of Engineering and Applied Sciences, Vol. 18, Issue 1 · 20 Dec 2025 · 2,761 accessesView PDFCite
Research ArticleOpen accessIn the author namesStable Isotope Diet Reconstruction of Feral Horses on the Sheldon National Wildlife Refuge, Nevada, USAMegan K. Nordquist, Todd F. Robinson, Gail H. Collins et al.Feral horse management has become a subject of significant controversy in the United States, resulting in part from opposing views of best management practices and limited empirical data. Feral horse densities increase in response to high reproductive rates and limited horse removal. with this increase, land managers are challenged with accurately quantifying horse diet selection and subsequent impacts on western … …American Journal of Animal and Veterinary Sciences, Vol. 19, Issue 2 · 4 Mar 2024 · 5,390 accessesView PDFCite

Research ArticleOpen accessIn the author namesBioaccumulation and Tissue Partitioning of Endosulfan by the Red Hybrid TilapiaDwight E. RobinsonThe frequent use of endosulfan in agricultural activity on steep slopes in Jamaica and subsequent contamination of rivers by the residues resulted in a need to assess the levels of bioaccumulation of sub-lethal doses of the insecticide in river fauna using Tilapia fish as a test subject. Bioconcentration of α- and β-endosulfan by the Red Hybrid Tilapia, from 0.0075 mg … …OnLine Journal of Biological Sciences, Vol. 15, Issue 3 · 29 Jun 2015 · 7,060 accessesView PDFCite
Research ArticleOpen accessIn the author namesBioactivity of the Alkaloids, Norharman and L-N-Methylcrotonosine/LinearisineMargelette Ellis-Tabanor, Dwight Robinson, Eric HyslopThe toxic effects of the alkaloids, Norharman and a mixture of L-N-Methylcrotonosine/Linearisine (M/L mixture), on two organisms, Gambusia puncticulata and Veronicella sloanei were determined. The effect of the alkaloids on the fecundity of Thiara granifera was also investigated. Norharman was harmless to G. puncticulata but the M/L mixture inflicted 55.5% mortality on fish populations. The alkaloids had narcotizing, repellent and … …OnLine Journal of Biological Sciences, Vol. 15, Issue 1 · 11 Apr 2015 · 7,202 accessesView PDFCite
Research ArticleOpen accessIn the author namesToxicity of Endosulfan to the Red Hybrid TilapiaDwight E. Robinson, Winroy WilliamsExposure of mature red hybrid Tilapia sp. to a range of sub-lethal concentrations of endosulfan for 21 days induced a spectrum of often not clearly distinguishable Behavioural Toxic Symptoms (BTS), ranging from reversible to eventually fatal responses.

Research ArticleOpen accessIn the author namesDietary β-glucan Leads to Increased TNF-α Production in the LungRadiah C. Minor, Melody L. Robinson-Wright, Morika Williams, Steven L. HurleyProblem statement: Beta (β)-glucan is notable for its ability to stimulate the immune system and as such β-glucan and products containing β-glucan are used as dietary supplements for livestock and companion animals. β-glucan has been shown to activate macrophages and neutrophils and modulate the production of certain cytokines, including the pro-inflammatory cytokine, Tumor Necrosis Factor Alpha (TNF-α). Because TNF-α is … …American Journal of Animal and Veterinary Sciences, Vol. 7, Issue 2 · 11 Jun 2012 · 7,507 accessesView PDFCite
Research ArticleOpen accessIn the author namesSoil Quality of Die off and Die Back Mangrove Grown at Al-Jubail Area (Saudi Arabia) of the Arabian GulfAkram Ali, Ahmed Alfarhan, Ernest Robinson, Wafa AltesanThe declining mangrove vegetation along the Arabian Gulf coast necessitates a thorough study for finding out the soil status and for rehabilitating the affected population.
