ABSTRACT This study mainly focused on assessing the Contribution of Food Crops in Promoting Livelihood in Rural Areas in Tanzania, particularly in Muleba District. The study guided with three specific objective: to examine the ways in which extension services and the land tenure systems affect the banana farming in Muleba District, to establish the impacts of climatic changes and banana diseases on the banana production in Muleba District and to assess the role of the government and other sta...
Cobalt is one of the natural elements that happens to be found throughout the natural environment. This natural element is present in trace amounts in sols, plants, water and our diet. When cobalt is in its pure form it is a steel-grey to black shinny hard metal. Cobalt can also exit as cobalt II and cobalt III which forms a number of both organic and inorganic salts. Cobalt in small proportion is essential to good health. Cobalt is only found in the environment in chemically bonded form...
ABSTRACT The objective o f the study was to obtain information on the existence o f Bradyrhizobium japonicum strains in Ghanaian soils, evaluate their effectiveness with the view to improving nodulation, nitrogen fixation and yield potential o f soybean. Eight soil series were screened for nodulation capabilities of soybean using six cultivars (four promiscuous and two non-promiscuous). The soils were Adenta, Akuse, Anyinase and Bekwai; the rest were Hatso, Nyigbenya, Nzima and Toje. Four cul...
Abstract Sugarcane production worldwide has been declining due to many challenges in several countries as their population grows. Earlier studies in the sugar industry have through years offered suggestions and solutions to how the ailing industry could be revived and improved but have not been successful. In Kenya, some sugarcane industries are closing down yet more sugar is needed. This study examined the challenges facing small scale sugarcane farming in Malava sub–county, Kakamega Coun...
Introduction Microbial fuel cells (MFCs) are bioreactors that convert chemical energy stored in the bonds of organic matters into electricity through biocatalysis of microorganisms (Potter, 1911; Cohen, 1931; Davis and Yarbrough, 1962; Moon et al., 2006). The schematic of a typical MFC is shown in Fig. 1. In the sketch below, the anodic and cathodic chamber are separated by a proton exchange membrane (PEM) (Wilkinson, 2000; Gil et al., 2003) that allows transport protons while blocking oxygen...
Abstract The Information on the effect of different land use systems on the aggregate stability and carbon sequestration is crucial for the recommendation of efficient land management practices. This study was conducted to evaluate the variation in aggregate stability and carbon sequestration under different land use systems in two agro ecological zones of south eastern Nigeria. The agro ecological zones were derived savannah and rainforest while the land use systems studied were cultivate...
This study comprises the synthesis and spectral properties of three chalcones 3-(4-n (dimethylamino)phenyl)-1-phenyl-(2E)-propen-1-one (DMAPPP),1-(4-methylphenyl)- 3-(4- N, N-dimethyl amino phenyl)-2-propen-1-one (MDMAPP) and 1-(4- chloridephenyl)-3-(4- N, N dimethyl amino phenyl)-2-propen-1-one (CPDAPP) in several organic solvents have been studied. Photophysical characteristics such as absorption, fluorescence spectra, stokes' shift, fluorescence and quantum yield of these chalcones w...
Abstract Various methods have been proposed for the improvement and maintenance of soil structure. In Ghana, the effects of agroforestry in the improvement of soil physical properties have not attracted much attention. This study seeks to determine the effects of agroforestry on the chemical and physical properties of soils in the semi-deciduous ecological zone. Three plots under Alley cropping and one plot under Woodlot (Leucaena leucocephala) were used. The soil properties determined includ...
Abstract: Biogas is the methane rich gas produced by anaerobic breakdown of organic wastes with the help of methanogenic bacteria under oxygen free environment. The objective of this study was to evaluate production of biogas from co-digestion of goat manure and sludges of beer under anaerobic condition. The three containers were interconnected with a plastic tube having a diameter of 1 cm. The acidified brime solution was prepared by dissolving NaCl in distilled water with few drops of sulf...
ABSTRACT Background: Transmission of HIV from pregnant mothers to their children is a key route of HIV transmission in Nigeria. Nigeria contributes up to 30% of the global PMTCT gap and coverage of PMTCT services has however remained low at less than 19% - falling short of both the universal access and National Strategic Plan targets. The current study intends to identify factors underlying the low uptake of PMTCT interventions in Abia state. Method: The study was conducted in ten out of the...
ABSTRACT This study determined the impacts of chemical application on plant biodiversity in comparison to the control ecosystems over a three-year period at Neudamm farm in Khomas Region, Namibia. In this study, for herbaceous plant sampling, a total of 40 (1m2 ) quadrats were randomly laid in each of the three chemically treated sites (treated in 2015, 2016 and 2017) and in the control site to record the herbaceous plant density, plant species composition, dry matter production and ground c...
ABSTRACT Football has become a widely followed „religion‟ just like Christianity. This has influenced a growth of scholarship on the subject from different theoretical positions. This study explores the sport world from a media centric standpoint. It looks at sports, particularly football from the lens of the media. It unearths how the media manufactures reality while at the same time exploring the discourses that prevail in the media with specific reference to football coaches. The study...
INTRODUCTION: Cooperatives are classified as one of the business organizations but operate in a special way different from all other forms of business enterprises. The distributive nature of cooperative provided that they must be owned, used and controlled by their members. In view of this, cooperatives are organized and managed through the system of large or small, multipurpose or single purpose and central or federal. All these systems put together are under direct coordination and ...
ABSTRACT Fishing is one of the main economic activities in Zanzibar. A few fish dealers are transforming this sector into mariculture. Among farmed fish is milkfish. Diseases are among the most important limitations in development of mariculture. Among others, vibriosis, a zoonotic disease of fish caused by bacteria from the genus Vibrio, is reported to cause significant losses in the industry. This study aimed at establishing the occurrence of Vibrio cholerae and Vibrio parahaemolyticus ...
