ABSTRACT Privacy and security are major essential human needs in various homes, offices e.t.c. Accessibility to adequate, durable, fashionable and affordable windows in our different buildings has been a problem to the society. Ability to have access to window of good quality and high durability of a price affordable to an average Nigerian has been a problem. This project here aims at production of a durable aluminium window. The aluminium window was subjected to different test, it ...
ABSTRACT Atmospheric emission of trace gases such as carbon (iv) oxide (co4), carbon (II) oxide (co), methane (ch4) e.t.c. associated with animal waste are world wild problem and may contribute to a detrimental impact on the environment in such a way that millions of people will be affected especially poor people who live in precarious location or depend on land for sustenance living. And this effect was determined by modeling the effect of trace gases on the environment. The two (2) main a...
Out-of-hospital cardiac arrest (OHCA) is a cessation of cardiac mechanical activity that occurs outside of the hospital setting and is confirmed by the absence of signs of circulation. OHCA affects nearly 1000 adult Americans every day, with overall survival rate of 10.4%. Based on previous work in this subject I try to calculate the joint probability distributions of the neurological outcomes of the OHCA outcomes in our records, based on the Event Demographics, Field Care, and Hospital Care....
The ultimate purpose of this project investigates COMPARATIVE STUDY OF THE ENGINEERING PROPERTIES OF SANDCRETE BLOCKS USING DIFFERENT BRANDS/GRADE OF CEMENT. Over 90% of physical infrastructures in Nigeria are being constructed using sandcrete blocks making it a very important material in building construction. It is widely used in Nigeria, Ghana, and other African countries as load bearing and non-load bearing walling units. For a long time in Nigeria, sandcrete blocks are manufactured in ma...
Abstract: Steel machining waste known as chips is a kind of waste that can be returned to the process of raw material for steel fabrication or else be traded as co-product of other industrial activities. The reuse of this product is of great importance owing to the economic and environmental aspects. This work investigates the effect of steel machining chips as additive on the properties of clay. The physical properties of the clay and steel machining chips composite were determined. The c...
Abstract The main aim of this research is to determine how energy improvement, efficiency and conservation can be achieved in industry such as the cement plant. Energy, is an essential ingredient for socio-economic development and economic growth. The objective of the energy system is to provide energy services. Energy services are the desired and useful products, processes or indeed services that result from the use of energy, such as for lighting, provision of air-conditioned indoor clima...
Abstract Outlier is a questionable plot value which differs greatly from the mean of all other replications of a specific treatment while trial error may occur as a result of a mistake in measurement or transcription during data collection or entry. The presence of any of the two confounds the inferences made from the data analyses especially the F-statistic whose estimate is based on sample means and variances. This report was intended to show how Genstat statistical software package assists...
Abstract Selected physical properties of Afzelia africanaseeds were determined at four moisture levels: 10.60%, 12.80%, 15.20% and 18.40% wet basis (w.b). The seeds were categorized in three batches according to their weights: Batch I (2g Batch III (3.99spectively. Arithmetic and geometric mean diameters, sphericity and projected area ranged from 13.5700.43-15.8230.41mm, 12.2450.33-14.4300.39mm, 57.800.07-75.600.03% and 186.21828.42-256.03712.98mmrespectively. Unit mass, unit volume, aspec...
ABSTRACT An Impact Test Apparatus was developed to determine the impact damage and bruise parameters of five fresh agricultural produce, namely: banana (Musa spp), tomato (Lycopersicon esculentum), sweet potato (Ipomea batatas), cassava tuber (Manihot esculenta) and lemon (Citrus limon) using Impact – Drop Height method. A constant impact energy of 0.9J – 4.5J was maintained as drop heights ranged from 0.20m – 1.00m. The bruise diameter, bruise depth, bruise width, bruise volume, bruise...
Physical and aerodynamic properties of African breadfruit (Treculia africana) seeds were studied at four moisture levels: 12.50, 15.00, 17.50 and 20.10% dry base (w.b). As moisture content increased from 10.50 to 20.10% (w.b), the average weight, major diameter, minor diameter, intermediate diameter, geometric mean diameter, arithmetic mean diameter of the seeds ranged from 0.35±0.08 to 0.60g±0.04g, 8.08±0.90 to 10.05±0.60mm, 4.04±0.53 to 5.00±0.10mm, 2.96±0.43 to 4.60±0.40mm, 4.52±0...

Abstract Global Petroleum reserves are currently getting depleted. Most of the newly discovered oil and gas fields are found in unconventional reserves. Hence there has arisen a need to drill deeper wells in offshore locations and in unconventional reservoirs. The depth and difficulty of drilling terrains has led to drilling operations incurring higher cost due to drilling time. Rate of Penetration is dependent on the several parameters such as: rotary speed(N), Weight-On-Bit, bit state, form...
This study examined the optimization of the transesterification reaction of sesame methyl esters (SMEs) with trimethylolpropane (TMP) to synthesise sesame biolubricant (SBL). Response surface methodology (RSM) using central composite design (CCD) was employed for the experimental design. Effects of temperature, mole ratio and reaction time on the yield of SBL were evaluated. The predicted yield after process optimization was found to agree satisfactorily with the experimental value. The o...
Jatropha curcas seed oil was studied for the synthesis of trimethylolpropane based biolube basestock via chemical transesterification of Jatropha methylester with trimethylolpropane (TMP) using calcium hydroxide catalyst. Reactions temperatures ranged between 80 and 160 C and methyl esters to TMP mole ratios ranged between 3:1 and 7:1. Product analysis, ester groups and physio-chemical properties were obtained by gas chromatography, Fourier transform infrared spectroscopy and American...
