Methyl ricinoleate 4 and methyl 13(S)-hydroxyoctadeca-9(Z),11(E)-dienoate 7 were subjected to epoxidation using mCPBA, or tert-butyl hydroperoxide in the presence of vanadyl acetylacetonate or titanium (IV) isopropoxide with D-(-)- or L-(+)-diisopropyl tartrate. Epoxidations using mCPBA gave equal quantities of the disatereoisomeric epoxides 5/6 an

Artificial intelligence (AI) is a revolutionary technology that has been used tremendously in the contemporary industrial revolution 4.0 technology. AI has played a crucial role in accelerating financial inclusion rate by easing the use of financial products. From the African perspectives, there is a very few notable uses of AI technologies in the

Several high-ranking watermarking schemes using neural networks have been proposed in order to make the watermark stronger to resist attacks. The ability of Artificial Neural Network, ANN to learn, do mapping, classify, and adapt has increased the interest of researcher in application of different types ANN in watermarking. In this paper, ANN based

This paper reviews the development of landslide thresholds from the perspective of rainfall and climate patterns. For certain, geology, morphology, lithology, etc., contribute to the initiation of the mass movement. However, the role of rainfall as the triggering mechanism of the landslide is vital as well. It has been proven by many researchers fr

Natural and environmental-friendly disposal of wastewater sludge is a great concern. Recently, biological treatment has played prominent roles in bioremediation of complex hydrocarbon- rich contaminants. Composting is quite an old biological-based process that is being practiced but it could not create a great impact in the minds of concerned resea

Since optimization of operational parameters is the key factor for solid-state bioconversion (SSB) by microorganisms, the growth,proliferation and establishment of two compatible mixed fungal cultures, Trichoderma harzianum with Phanerochaete chrysosporium 2094 and T. harzianum with Mucor hiemalis were evaluated under di6erent operational parameter

Religion and spirituality (R/S) have immense potential in influencing the effectiveness of patient counselling in the healthcare setting. Although substantial literature has studied the relation of religion, spirituality and health, a limited number of studies have investigated the effect of religious/spiritual practices in patient counselling. Thi

Azo dye is widely used in the textile industry since it is cost effective and simple to use . However, it becomes a continuous source of environmental pollution due to its carcinogenicity and toxicity. Various methods had been used to remove the azo dye in solution. One of the famous and repeatedly used is Fenton process. The Fenton’s process is

The purpose of this paper is to determine the drift loss and pressure drop characteristics of cellular type drift eliminator and also those made of wood and cement-asbestos in a spray filled tower. The investigation were conducted with two and three stages of both wooden drift eliminators (WDE) and cement asbestos drift eliminators (CADE) with vari

Introduction: Proteomic profiling in schizophrenia was performed to elucidate significant biomarkers of this chronic complex disease. Any discovery of remarkably expressed proteins during the proteomic profiling is useful for translational studies and enhancement of basic science knowledge of schizophrenia. Due to recent advancement in different pr
