Abstract: Kombolcha leather industry produces huge amounts of inorganic and organic wastes which pollute the adjacent environment including Abba Sharo River. This study was focused on characterizing the physic-chemical parameters of Kombolcha tannery effluent and evaluates its impact on the water quality of receiving Abba Sharo River water. Accordingly, two tannery effluent samples along wastewater channel at different distances have been taken and three river water samples were collected al...
TITLE:IMPLICATIONS OF GLOBAL WARMING ON CONTINENTAL EUROPE Human-driven climate change by global warming poses as a critical peril to continental Europe in the way it impacts ecosystem, mankind, and economies. The consequences on the continent could be far-reaching and should easily stand as an imminent challenge that needs to be addressed with. The most critical issues include increased frequency in extreme weather events and high intensity. Heatwaves, floods, and storms have become regul...
In politics today, the media are very important in reporting political activities. There are certain ways they report political actors which allow the people to develop a level of perception about the politicians. The media often frame reports, not only for people on what they should think about (agenda setting)but on how they should think (framing). This study critically examines the types of framing that the media explored during the 2015 presidential elections in Nigeria. TABLE OF CONTEN...
Abstract: Integrated vector management (IVM) is defined as a rational decision-making process for the optimal use of resources for vector control. The IVM approach is based on the premise that effective control of vectors and the diseases they transmit is not the sole preserve of the health sector. It requires the collaboration and participation of communities and other stakeholders in public and private sectors. Community participation is key to the success of IVM implementation at the loca...
ABSTRACT Achlya megasperma sporulated best s.t 30°C and at pH 7.0 to 9.0. Light had no effect on forration of the sporangia. Certain concentrations of CaCl-,., ^ulcitol. Mg SO^^H^O, Malt extract, neptone and Yeast extract enhanced sporangial formation. The mineral salts, CuS04 .5H20, FeCljs MnS04 .4H20 and Zn Cl2 depressed sporangial formation. Gemmae were produced in great quantities in solutions of 0.1, 0.2 and 0,4 per cent haemoglobin and 1x0 ^ and 0_5M Zn Cl^. Sporangial formation was a...
ABSTRACT The efficacy of silica obtained from our local sand as a carrier in synthesis of Nickel-Silica catalyst was investigated. Six samples of soil were collected from two different sites (comprising five white coloured samples collected from Iva valley, lower part of Milliken hill, namely: pottery 2 (P2), down iva (DI), run-off iva (ROI), pottery rock (POR), white chalk (WTC) and one brown coloured sample (UdS) collected from Udi Siding) in Enugu, Nigeria. Prior to treatment by flotation...
Abstract: One health’ (OH) is a cross-sectoral approach that addresses human, plant, animal, and environmental health problems. The initiative stems from recognition of the convoluted linkages among global health risks and the need for coherent multipronged countermeasures. For agriculture, environmental degradation and biodiversity depletion wrought by heavy reliance on inorganic inputs to meet the needs of the ever-growing human population, are a matter of societal concern. Agroecologica...
Nutrient paucity in the soil poses challenge to global production of food. The use of synthetic nitrogen fertilizers to boost crop yield is a recurrent farming practice, despite their unfavourable effects and hazard to the environment and human population. This study was aimed at developing an environmental friendly, low cost inoculation technology for the cultivation of soybeans. Laboratory approach was used in the production of the biofertilizer, which started with biochemical characterizat...
ABSTRACT This study used a 2x2x2 factorial design to examine framing, certainty and gender effects on security strategy decision. One hundred and twenty (60 male, 60 female) first year students of psychology, University of Nigeria, Nsukka, whose ages ranged from 16-29 years (M = 20.35 years, SD =2.85 years) participated in the study. Framing was varied into positive and negative framing conditions certainty was varied into certainty and uncertainty conditions, while gender was categorized in...
Abstract The essence of science education is to produce confident, self-employable, scientifically, and technically sound men and women. Unfortunately, the chemistry curriculum appears not to have achieved much of its objectives. These lapses might have been caused by non-availability and usability of chemistry laboratory facilities for teaching organic chemistry. It is against this background that this study examined the extent of availability and usability of chemistry laboratory facilit...
ABSTRACT In this study, the potential effects of animal derived organic manure (cow dung, poultry droppings), saw dust and NPK fertilizer on the bioremediation of petroleum hydrocarbon contaminated soil was investigated. The rate of biodegradation was studied for the period of 10 weeks under laboratory conditions. The biodegradation data were fitted to eight models, four of which are based on microbial growth rate and the other four based on order of reaction. Results obtained show that biore...
ABSTRACT With the aid of Global Positioning System (GPS) and Satellite Aerial Photo, a comparative characterization and mapping of soil gully erosion features on two geological formations were carried out in Nsukka area of eastern Nigeria. The two geological formations were Ajali and Mamu formations. The study involved the use of base map created using a Geographic Information System (GIS) (GPS Track Marker) and Satellite Photo downloaded from the internet using the same GIS (GPS Track Marker...
ABSTRACT This study on the impacts of climate change on farming activities was conducted in Dandume Local Government Area of Kastina State. To capture data on the impact of climate change on farming activities based on the perceptions of the farmers, 150 questionnaires were administered and retrieved. The data were analyzed using descriptive statistics (percentage, bar chart, etc.). About 57.33% of the respondents percept that, there was increase in rainfall while 20% of the respondents belie...
Abstract: Biogas production using anaerobic digestion of organic waste materials provides an alternative environmentally friendly renewable energy. In this study, the production of biogas from co-digestion of wheat straw with poultry and goat manure was evaluated in seven treatment under mesophilic condition 380C for30 days of retention time, using a batch digester in Botanical and Central Laboratories of Haramaya University. Total solids, volatile solids, percent moisture content, pH, organ...
Abstract This paper is about microfinance viewed as a social change “tool kit” and its consequent effects on livelihoods of women of Bunyala, especially those involved in small-scale diary farming. The study investigated microfinance strategies, effects and challenges encountered by the farmers. Census techniques were applied in collecting primary data on all 93 dairy farmers in Bunyala District. The main instruments of data collection were questionnaires and document analysis. Data was ...
