IJSET@2014 Page 707 Effects of Temperature on Ilmenite During Concentration of Iron in Laterites Using Charcoal and Separation using Magnetic Separation
(2014)Effect of temperature on ilmenite minerals found in laterites has been investigated. It was found that during reduction of iron minerals in laterites to magnetite using charcoal at temperatures of about 500-700oC, ilmenite ... -
Immunopathological effects of some Biomphalaria pfeifferi proteins against Schistosoma mansoni infection in BALB/c mice
(2019-04)Intestinal schistosomiasis remains a major cause of morbidity and mortality in most parts of the world, despite decades of widespread chemotherapy use. The present study determined the intermediate host proteins expressing ... -
Implementation of genomics research in Africa: challenges and recommendations
(2018-01-16)Background: There is exponential growth in the interest and implementation of genomics research in Africa. This growth has been facilitated by the Human Hereditary and Health in Africa (H3Africa) initiative, which aims to ... -
Impure Hydrazone Preparation from Chicken Dung
(IISTE, 2020-09-30)Hydrazones are strong reducing agents. Some hydrazones like hydrazine are is highly toxic and unstable and are therefore found dissolved in water. Chicken dung contains amines and uric acid that are potential sources of ... -
INFLUENCE OF GRAZING BY LARGE MAMMALS ON THE SPIDER COMMUNITY OF A KENYAN SAVANNA BIOME
(Bio One complete, 2005-09)Pitfall trap and sweep net samples were taken over a period of fifteen months (2002– 2003) in the Kenya Long-term Exclosure Experiment (KLEE), in which the presence of domestic and wild herbivores have been independently ... -
The influence of health technology on principal-agent relationship: a study of virtual doctor consultations in Rwanda
(2020-10-26)Use of technology in health care delivery is considered as one solution to speed up the health care delivery in underserved areas. Because of this, a number of health technologies have been brought into play, such as ... -
The influence of reaction times on structural, optical and luminescence properties of cadmium telluride nanoparticles prepared by wet-chemical process
(2016-01)This paper explains one pot synthesis of type II water soluble L-cysteine capped cadmium telluride (CdTe) core shell quantum dots using cadmium acetate, potassium tellurite and L-cysteine as the starting materials. The ... -
Insecticidal Activity of Elaeodendron schweinfurthianum Extracts and Compounds against Sitophilus zeamais Motschulsky
(2020-11)Agricultural production is constrained by pests which cause serious post-harvest losses in African. Maize weevil (Sitophilus zeamais Motschulsky) is one of the most destructive insect pests of maize. Effective synthetic ... -
Insecticidal Activity of Ocimum Suave Willd Extracts and Compounds against Sitophilus Zeamais Motschulsky
(2020-11-28)Insect pests cause significant loss of maize production in Africa. Among pests of maize, beetles are the most important, with the maize weevil (Sitophilus zeamais Motsch.) and the larger grain borer (Prostephanus truncatus ... -
Insecticidal Drimane Sesquiterpenes from Warburgia ugandensis against Maize Pests
(2021)Sitophilus zeamais and Prostephanus truncatus, the destructive pests of maize in Africa, cause extensive tunneling in maize grain leading to conversion of maize grain into flour within a very short time. Small-scale farmers ... -
