Energy Production from Landfill Technology Context of Improved Solid Waste and Management in Khartoum State – Sudan

AbstractRecently, the world has begun to experience depletion in energy resources and this issuehas become a major concern. Sudan faces a problem with limited fossil fuel resources andan increase in waste accumulation as population growth and economic development playan important role in increasing solid waste generation in addition to increasing energydemand. Sudan is one of the most densely populated countries in Africa, with an annualgrowth of 2%. We find that about 20% of the popula...

Composting Of Organically Amended/Treated Hardwood And Softwood Sawdust

ABSTRACT Sawdust is a major waste produced by the wood industry. Adding value to sawdust through composting is one of the surest means by which environmental pollution could be minimized. About 500 kg of softwood and hardwood sawdust were separately mixed with mucuna leaves and kitchen waste in the ratio of 3:1:1 on weight basis and heaped using effluent from abattoir to develop composts. Objectives of the study were to monitor changes in the physico-chemical properties, NH4 + ‒ N, ...

PATHOLOGICAL ASPECTS OF SEED-BORNE MYCOFLORA OF Pinus caribaea Morelet var. hondurensis

ABSTRACT A survey of, the mycoflora of three seed lots of Pinus caribaea var. hondurensis was carried out using the incubation tests for the detection of seed-borne fungi on agricultural seeds.

A. niger, A. tamarii, Botrvtis sp., BotryQdiplQd.i.a theobromae, Chaetomium funicola, £. globosum, £. indiCUTO, Cladosporium oxvsporum, Pendrophpma sp., Fysa.riym ecruiseti, F. moniliforme var. intermedi...

Assessment of Post-harvest Handling Practices and Losses of Maize in Ejura-sekyeredumase Municipality

 Introduction to the background of the study: Maize (Zea mays) is the highest produced cereal crop and the most widely consumed food in Ghana with increasing production since 1965 (FAO, 2008; Morris et al., 1999). Maize is cultivated in all the ten regions of the country however the leading producing areas are mainly in the middle-southern part (Brong Ahafo, Eastern and Ashanti provinces) where 84 percent of the maize is grown, with the remaining 16 percent being grown in the northern re...

Ergonomic modification and performance evaluation of a shoulder-strapped brush cutter

Ergonomic studies were carried out on selected shoulder-strap brush cutters to evaluate some deficient ergonomic factors associated with their operations. These deficiencies were used as basis for modification. Contextual interview and field interactions were used to obtain ergonomic data that are descriptively analyzed. Results of ergonomic assessment shows that operators are subjected to pains around the neck, shoulders, upper arm and fingers which are largely traceable to shoulde...

A fuzzy-Based Decision Support System for Soil Selection in Olericulture

With the advent of modern computer technology, the field of Artificial Intelligence is playing a significant role in improving almost every spectrum of human life. In the field of agriculture, there is always need for optimality with improved crop yield. This paper dwells majorly on the application of fuzzy logic to predict crop type with optimal crop yield based on available soil nutrients. Some soil data samples were collected from the department of soil science, Federal University of Agric...

Agricultural Biomass Waste (cow Dung) collection, storage and use in Anaerobic Digestion with CHP

How Much quantity of dung needs to be collected to be used in an Anaerobic Digestion process to make it economically viable? How can the collected dung be used to generate electricity and heat in a combined heat and power? What CHP technology gives you the best electrical to thermal heat ratio? 

The Effect Of Total Dissolved Solids, Salinity And Electrical Conductivity Parameters Of Water On Abundance Of Anopheles Mosquito Larvae In Different Breeding Sites Of Kapiri Mposhi

Malaria is a global public health problem, caused by malaria parasites transmitted by the vector adult female Anopheles mosquitoes. The life cycle of Anopheles mosquito (Order: Diptera) has six stages egg, four larvae instars and pupa. The immature stages are aquatic and determine the abundance, distribution and fitness of the adult Anopheles mosquito. The physicochemical parameters (Conductivity, Salinity and Total Dissolved solids) of water affects survival and development of the larvae. Th...

Construction of a Battery Cage with Manually Operated Waste Conveyor

This is a research work carried out on battery cage system of poultry management. It's all about how to minimize waste from poultry birds and also how to convey waste by employing the help of a belt conveyor 

EFFECTS OF LIQUID WASTES FROM AUTOMOBILE WORKSHOPS ON PROPERTIES OF SOILS IN ENUGU STATE, NIGERIA

ABSTRACT: This study was carried out in Udi, Udenu and Nsukka Local Government Areas, in Enugu state. The effects of liquid wastes from automobile workshops on some selected soil properties of the study area were investigated. Auger samples were collected at two depths, (surface, 0- 20cm) and (subsurface, 20- 40cm) of automobile wastes contaminated sites and 100m away for uncontaminated sites. Core samples were collected from both soils and surface samples were again collected for planting m...

Review on Some Plants as Bio-pesticides

Abstract: The study used Onion (Allium Cepa), Garlic (Allium Sativum L.) and Sour Orange (Citrus Aurantium) to assess their effectiveness as bio- pesticides. The study also revealed that plants play vital roles towards the storage of many food stuffs. The consideration for the used extracts of plants origin is that they were easily biodegradable, effective on some pests and considered safer in pest control operations as they minimized pesticide residues and also ensured  safety of th...

A comparative study of noise pollution levels in Ilorin metropolis

The noise pollution is a major problem&nbsp;for the quality of life in urban areas. This study&nbsp;was conducted to compare the noise pollution&nbsp;levels at busy roads/road junctions, passengers&nbsp;loading parks, commercial, industrial and residential&nbsp;areas in Ilorin metropolis. A total number&nbsp;of 47-locations were selected within the metropolis.&nbsp;Statistical analysis shows significant difference&nbsp;(P < 0.05) in noise pollution levels between industrial&nbsp;areas and low...

Isolation and characterization of PGPR from the rhizopheres of selected vegetables in Ogun state

ABSTRACT Beneficial bacteria that colonize the root of plants and are capable of stimulating the growth of plants directly or indirectly are called plant-growth promoting rhizobacteria. The objective of this study was to isolate and characterize plant-growth promoting rhizobacteria from the rhizosphere of some selected vegetables collected at different locations in Ago-iwoye, Oru and Ijebu-Igbo in Ijebu-North local Government Area of Ogun state, using general microbiological and biochemical t...

Thermodynamic limitations to nuclear energy deployment as a greenhouse gas mitigation technology

To both replace fossil-fuel-energy use and meet the future energy demands, nuclear energy production would have to increase by 10.5% per year from 2010 to 2050. This large growth rate creates a cannibalistic effect, where nuclear energy must be used to supply the energy for future nuclear power plants. This study showed that the limit of ore grade to offset greenhouse gas emissions is significantly higher than the purely thermodynamic limit set by energy payback times found in the literature....
