ABSTRACT Napier grass (Pennisetum purpuruem), an indigenous tropical African clumping grass, is the major livestock feed used by many farmers in zero-grazing systems in Kenya. However, Napier stunt (Ns) disease caused by a phytoplasma has adversely affected napier production at rates of up to 90% in many smallholder fields. A number of wild grasses growing around napier fields have also been observed to host phytoplasma. This includes Hyparrhenia rufa grass that has been documented to h...
ABSTRACT The study examined the impact played by strategic management on the performance of selected oil and non-oil production firms in Lagos. Data were collected from both primary and secondary sources. The primary source involved the use of a well structured questionnaire to capture the current practice of strategic management in some production firms and impacts on organizational performance. The secondary data were obtained from textbooks, journals, newspapers and government publ...
ABSTRACT Transport infrastructure is the fixed part of a transport system. Transport infrastructure development remains one of the major tools for achieving the much needed rapid economic growth in Nigeria. Hence, the study aims at investigating the effect of funding on transport infrastructure development and the implication of this to the economy. The scope of the study was confined within the time frame of 1981-2004. The researcher used GDP, Budgetary Allocation to Transport and th...
ABSTRACTProjects have become an integral part of organizations’ strategy. Health projects in particular, have been found to carry out a critical function in enhancing the well-being of society. In Kenya, many health projects are funded by donors. Although the amounts of funding from donors have been rising over the years, most donor funded health projects in Kenya are not performing well. According to the World Health Organization, almost 50 percent of health projects in Kenya do not achiev...
ABSTRACTConstruction industry is one of the most important sectors that stimulate economic growth in any country. An increasing trade activity in Kenya has created a great demand for more and better infrastructure such as road networks, communication, buildings and utilities such as power, water and sewer systems. From an economic point of view, construction industry has become one of the most vibrant economic sector in Kenya today and has attracted a large number of investors. Delays in comp...
ABSTRACTAdvancement in civilization in developing countries with unmatched capacity to dispose of the vast amounts of wastes generated poises public health concerns and adds strain on diminishing land space in emerging urban centers. A sustainable efficient way of waste management is needful, to which end, enhanced composting through employment of appropriate biopreparations offers environmentally safe strategy. This work sought to improve the management of Municipal Solid Waste (MSW) by asse...
ABSTRACTMicrobial contamination in laboratories and hospitals is becoming serious problem worldwide and characterization of such contaminants offer hope for treating some hospital and laboratory acquired infections (LAI). Microbial contaminants on benches, floors, media and in equipment can be influenced by temperature, humidity, nutrient media used in the laboratories as well as storage conditions of the media. Therefore there is need to determine the microbial sources, isolate and identify ...
ABSTRACTIn high Plasmodium transmission regions, malaria caused by Plasmodium falciparum is the leading cause of malaria-related morbidity and mortality among children under the age of 5 years. Severe malaria anaemia (SMA) is the most common cause of malaria burden in holoendemic P. falciparum transmission regions such. Although the mechanisms underlying development of SMA are poorly understood, direct and indirect lysis of erythrocytes, suppression of erythropoiesis, erythrophagocytosis, dys...
ABSTRACTPlants appear to be almost an exclusive source of medicine to the worlds’ gradually increasing population with substances derived from them constituting a big percentage of all prescribed conventional medicines and other products. This puts pressure on the demand for medicinal plants, most of which are sourced from the wild. Zanthoxylum gilletii is an African indigenous deciduous tree which is overexploited for its medicinal use among many communities. This species has its habitat e...
ABSTRACTStriga weeds are root parasitic plants that affect production of food in sub-Saharan Africa. Striga genus includes species; Striga hermonthica, S. gesnerioides, S. aspera, S. asiatica and S. forbesii with S. hermonthica being the most widely spread in the semi-arid tropical African zones. The most effective Striga control strategy is to exploit natural resistance. Wild grasses contain a resistance mechanism that enables them to resist Striga infection resulting in low Striga quantity ...
ABSTRACTBacterial infections are responsible for numerous deaths every year worldwide. On average, 80% of the African populations cannot afford conventional drugs. Moreover, many synthetic antibiotics are associated with side effects and progressive increase in antimicrobial resistance. Currently, there is growing interest in discovering new antibacterial agents from medicinal plants. About 60% of the population living in developing countries depends on herbal remedies for healthcare needs. T...
ABSTRACTEnterobacterial constitute a large family of Gram-negative bacteria which reside in the intestines of the animals and can be pathogenic. Penicillins and fluoroquinolones have been used as antibiotics to combat enterobacterial infections. Challenges in treatment of enterobacterial infections with conventional drugs have led the physicians to opt for phyto products and other alternative medicine for treatment of enterobacterial infections. Heavy bacterial l...
ABSTRACTDiabetes is increasingly affecting a growing number of patients and seriously reducing their quality of life. Use of conventional drugs in diabetes management is expensive, thus, unaffordable to most patients. Furthermore most of these conventional drugs are associated with undesirable side effects. Incorporation of herbal medicine into conventional healthcare system may significantly improve the overall management of Diabetes. Evaluation of efficacy and safety by scientific method is...
ABSTRACTWarburgia ugandensis Sprague is a highly valued medicinal plant which is over-exploited for its medicinal use among many communities. Encroachment and fragmentation of the species habitat has led to a notable decrease in its population size and distribution to the level that warrant some conservation efforts. Moreover, information on diversity in its antimicrobial activity and phytochemical profiles is lacking. The aim of this study was to evaluate variations in antimicrobial activity...
ABSTRACTCassava (Manihot esculenta Crantz), is an energy giving food and has a crucial role in many of the world‟s least developed countries by providing not only food but also economic security. However, its productivity has been hampered by constraints that reduce yields. One of the biotic constraints is cassava anthracnose disease (CAD) caused by pathogen Colletotrichum gloeosporioides, results into more than 30 per cent reduction of produce in the fields. The use of conventional methods...
