The idea of utilizing the agricultural residues as energy resources is considerably attractive. The objectives of study are to determine the characteristics and mechanical properties of the briquettes produced from sawdust (SWD) and maize (Zea mays) grain dust (MGD) using cassava starch as binding resin. Samples of various briquettes were produced...

Water occurred naturally and it is used widely for drinking, cooking, washing, agricultural activities, population expansion, urbanization, generation of power, and industrialization. Availability and accessibility are used to estimate the percentage of the population using safe water sources. However, potable water is inaccessible and unavailable...

The demand for engineering education and graduates is increasing daily because the current service and technological designs are unable to meet the needs of the society and the expected dramatic increase in the future. The emerging skill gap requires a shift in the type of expertise required of young professionals that will be needed to success...

This study evaluates two different plastering materials for mud buildings. The mud was first mixed with water and treaded upon. Straw was added as stabilizers to the mud paste. A little amount of straw spread on the surface of the mixture was remixed and left for a period of one week in which the mixture was remixed at interval of three days. The m...

Segregation of solid module significantly affects the quality of concrete. Which can be measured through compressive quality test, to decide the limit of the heap that a solid can convey which is connected unswervingly and the devastating burden per unit surface region of the connected burden to the solid. The accompanying states of total was utili...

The transesterification of used cooking oil with short-chain alcohols, in the presence of base catalyst sodium hydroxide (NaOH) and methanol as solvent, by means of single step batch process in order to obtain biodiesel fuel was studied using a reaction ratio of 6:1 for alcohol: oil.

Termite hills are described as the structure built by termite using soil in the surrounding or within the earth. The mound has extremely hard walls constructed from bits of soil cemented with saliva and baked by the sun. This research is to determine the compressive strength of termite hill soil stabilized with rice husk. The study investigated the...

This study assessed the nutritional quality attributes of maize (Zea mays) stored in metallic silos for a period of eight months in the humid tropics of Nigeria. The nutritional properties (NP) evaluated are percentage ash content (AC), crude fibre (CF), crude protein (CP), carbohydrate content (CHO), fat content (FC), and energy value (EV). The in...

Strength of concrete is one of the most important properties of concrete that is measured through compressive strength test, to determine the capacity of the load that a concrete can carry which is applied directly and the crushing load per unit surface area of the applied load to the concrete. In this research work the following shapes of aggregat...

This paper presents the effect of varying overhead tank position on the designed Elemebiri community water distribution network. Field survey and measurement were carried out to determine the population and water demand of the study area. The water supply distribution network model (WASDIM) was used in this research. The WASDIM model is based on th...

Two different optimization models for prediction of compressive strength of lateritic blocks was performed using statistical analysis for the lateritic block data obtained from experimental work done in this study. The models used are Scheffee’s and Osadebe’s optimization theories to predict the compressive strength of lateritic blocks. The results...

A study was carried to develop model equations for selecting optimum storage parameters for stored cabbages in passive evaporative cooling structures.Three sets of four different types of passive evaporative cooling structures made of two different materials; clay and aluminium were designed and constructed as part of the study. One set consists of...

A study was carried out on the effect of salt solution on mycelial growth of fruit spoilage fungi in passive evaporative cooling structures. Three sets of four different types of passive evaporative cooling structures made of two different materials, clay and aluminium were constructed. One set consists of four separate cooling chambers. Two coolin...

A multipurpose passive evaporative cooler was designed, constructed and its performance evaluated by determining the adiabatic efficiency. The multi-purpose passive evaporative cooling system consists of three compartments whose outer and inner cooling chambers were made of galvanize steel. The interspace was filled with sandy loam. The cold storag...

A study was conducted on the impact of soil inter-space bulk density and moisture content on the vitamin A content of stored oranges in passive evaporative cooling structures. Two sets of four different types of passive evaporative cooling structures made of two different materials, clay and aluminium were constructed. One set consists of four sepa...

The effect of poultry waste application on physicochemical and biological properties of sandy clay loam soil was investigated on a 7m X 7m plot of land. Plot was divided into four portions and 7.5kg each of broiler, cockerel and layers waste was applied to plot A, B, and C in slurry form while plot D was used as control(no application) for eight we...

Potential hazards to the health of grain storage workers have increased over the years basically because of the sophistication in storage systems, grain dust, biological contaminants and chemicals used in storage. To identify the hazards of grain storage in southwest and middle belt regions of Nigeria, analysis of medical records, interviews and qu...

A study was conducted to assess the effect of packaging materials on some nutritional qualities of fruit and vegetables (garden egg, banana and tomatoes) stored in a passive evaporative cooler. The fruit and vegetables were stored inside a perforated plastic container and sisal sack before placement inside an evaporative cooler. The results obtaine...

Pozzolanic materials have long demonstrated their effectiveness in producing high-performance concrete. Artificial pozzolanas such as rice husk ash have gained acceptance as supplementary cementing materials in many parts of the world. This work evaluates the potentials of groundnut shell ash (GSA) as a partial replacement for ordinary Portland cem...

The aim of this study was to evaluate the performance of wooden silo for long-term (wet and dry seasons) storage of maize (Zea mays) under tropical climate. A one tonne capacity, 1.4m diameter and 1.1m height hexagonal wooden silo was constructed and erected in Minna. The silo was of Iroko (Melicia excelsa) ribs and exterior grade (redwood) plywood...
