Most variable speed wind turbines have pitch angle control mechanisms and one of their objectives is to extract maximum power from available wind speed. By adjusting pitch angles of wind turbine. In this research the use of pitch angle control for wind turbine equipped with self-exited induction generators (SEIGs) and power electronic converters is presented. To extract the maximum available power from the wind, the wind turbine is controlled using pitch angle control based on power sign...
INTRODUCTION A fungus is any member of a large group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms. These organisms are classified as a kingdom, Fungi, which are separate from plants, animals, protists, and bacteria. One major difference is that fungal cells have cell walls that contain chitin, unlike the cell walls of plants and some protists, which contain cellulose, and unlike the cell walls of bacteria. These and ot...
ABSTRACT Topic Prevalence of urinary tract infections among pregnant mothers attending ante natal visits in Rugazi health center IV. Research Objectives: To determine the proportion of urinary tract infections among pregnant mothers attending ante natal visits in Rugazi health center IV. To determine factors contributing to the prevalence of urinary tract infection among pregnant mothers attending ante natal visits in Rugazi health center IV. Study design: A cross sectional study where all pr...
Abstract: The incorporation of entomopathogenic fungi as biocontrol agents into Integrated Pest Management (IPM) programs without doubt, has been highly effective. The ability of these fungal pathogens such as Beauveria bassiana and Metarhizium anisopliae to exist as endophytes in plants and protect their colonized host plants against the primary herbivore pests has widely been reported. Aside this sole role of pest management that has been traditionally ascribed to fungal endophytes, recent...
ABSTRACT Infection prevention and control is not only crucial in protecting patients, health care workers and visitors in health care settings from health care associated infections which are protracted cause of morbidity and mortality but also in preparation and response to communicable disease crisis. Despite the high burden of health care associated infections and need for enhanced prevention and control of these infections in Vihiga Sub County, factors influencing infection prevention and...
INTRODUCTION Mycotoxins are pharmacologically active mold metabolites produced in a strain-specific way that elicit some complicated toxicological activities (Bennett, 2003). Mycotoxins could also be described as secondary metabolites produced by a wide variety of organisms categorized as fungi, including mushrooms, yeasts and molds. The term mycotoxin was used for the first time in 1961 in the aftermath of a veterinary crisis in England, during which thousands of animals died. The disease wa...
ABSTRACT Schistosomiasis remains endemic in Ghana, with Schistosoma mansoni and S. haematobium being the two dominant species of the schistosome parasites. In some parts of Africa, previous works indicated the occurrence of pairings between these two species, resulting in the production of non-viable eggs (parthenogenesis). In Ghana, although both species occur in sympatry, it is yet to be shown whether this can lead to hetero-specific pairing within the definitive host leading to consequent ...

ABSTRACT This study explores the use of lactic acid bacteria from fresh salad vegetables to inhibit fungal growth. The antifungal assay was done using the agar well diffusion method as reported by Schillinger and Lucke (1989). The largest zone of inhibition (25mm) was recorded by the antagonistic activity of the isolate identified to Lactobacillus plantarum against Candida albicans ATCC 90029. No activity was recorded against Candida parapsilosis ATCC 22019, C. valida UCH 1508, C. pseudotrop...
Intestinal parasitic infections caused mainly by protozoa and helminths are most prevalent in tropical and subtropical regions of the world where adequate water and proper sanitation are lacking. Helminthiasis has been listed among the three most prevalent diseases in Tharaka-Nithi County. The residents are mainly small scale nonmechanized farmers hence there is frequent contact with the soil. Chronic parasitic infection among students negatively affects their health, nutrition, cognitive dev...
ABSTRACT The specific objective of this study was to evaluate the standard of cleanliness of intracavitory transducers by Sonographers in Enugu; the exposure to infectious diseases and the specific regulatory guidelines for infection control in ultrasound laboratory.The research was a non-experimental cross sectional study. The sample size was 46 sonographers. The primary source of data was questionnaire. The result shows that 43.48% of Sonographers clean their intracavitory ultrasound tran...
Abstract A study was conducted in Kampala International University- Teaching Hospital accident and emergency department between July 2013 to October 2013 to assess the awareness and practises of infection prevention amongst health care workers at their work place. The specific objectives of this study were to assess the practices of the staff in emergency rooms on the standard protocols observed in infections prevention, to identify the roles played by the administration in infection control...
ABSTRACT The socioeconomic burden of pollen and fungi spores allergy are very high in terms of hospitalization, treatment, lethargy, poor concentration and behavioral changes which impact negatively on adults and children. The study of atmospheric pollen and fungal spores in the six geopolitical zones of Nigeria was carried out from June 2011 to May 2012. The aims of the study are to determine the seasonal prevalence of atmospheric pollen and fungal spores, examine the impacts of weather par...
SUMMARY Rats experimentally infected with about 10 CFU or more of Campylobacter jejuns were promptly colonized. Campylobacter jejuni was recovered from faecal cultures of infected rats for up to 17 weeks post infection. The infected rats did not succumb to diarrhoea throughout the experiment. Haemagglutination assay was used to detect adhesins of Campylobacter jejuni isolated locally. Five out of 15 (33 percent) of the strains tested agglutinated erythrocytes of human blood group A+ and guine...
ABSTRACT The potential of alkaloids from Panicum maximum floret infected with the fungus Tilletia ayresii in the control of uterine contraction in Sprague-Dawley rats was investigated using bioassay guided fractionation technique. Disease incidence study revealed that smut disease was significantly higher in Ikorodu site (95.00%) when compared with Akoka site (69.00%) and Isolo site (72.00%). The height of disease incidence was between the months of August and November. Thirteen species of f...
