Light directly influence eachelement of human life and is the greatestcentralecological input after human basic needs (food, shelter and clothing) in regulating body functions. Human life and activities especially the process of acquiring knowledge and skills depend on light. The essential mission of schools is to provide good learning environmentsof which light is a key factor. Therefore, lighting is an important factor in designing classrooms. Artificial classroom lighting impact on students' academic performance is underestimated. In spite of technological advancements that have greatly improved the quality of artificial lighting, most secondary schools classrooms in Nairobi County of Kenya have insufficient artificial lighting and this negatively influence the overall students' academic performance. The objective of this study was to assess artificial classroom lighting effects on secondary school students' academic performance....

The use of edible oils as core oil in the foundry industries has remained the conventional oil widely used in the past decade. The search for alternative core oils has become challenging due to high demand of these edible oils for consumption and industrial applications. Some non-consumable oils such as neem, jatropha, castor and sheabutter oils were evaluated as core binders in foundry sand. These plants are found littered/wasted around in major parts of Nigeria and its potentials are yet to be ultilised maximally by countrymen. Core specimen containing silica sand bonded with starch, water in variable proportions of non-edible oil were tested for moisture content, permeability, tensile strength, green/baked compressive strength, baked collapsibility and fatty acid to determine if its felicitous for foundry core application. An optimum baked strength of 1648kN/m2 was obtainable in a mixture of 6% neem seed oil, 2% water, 2% starch and balance sand. This can be attributed to its high degree of unsaturated properties contained.

In this paper, a model for "Smart Hand Rehabilitation Glove", which is a cost effective and convenient method of exercising was proposed. Traditional Stroke Rehabilitation consists of motor exercises that are needed to be performed by the patient in the supervision of assistants for muscle memory regeneration. However, such Stroke Rehabilitation is inconvenient to the patient and expensive as well. The Glove can be switch controlled for Automatic Replication of Hand Movements, can be in the form of a Replication Glove which copies the movements of the unaffected hand to the affected hand or a brain-controlled glove for exercising.

There are a large number of commercially available prosthetic feet. Most of the design can be divided into two classes, articulated and non-articulated feet. One common non-articulated foot is the SACH. The solid ankle cushion heel foot referred to as the SACH foot has a rigid keel. Due to the rigidity (SACH Feet) and high cost of the feet (MPC Feet), non rigid designs are necessary to improve the performance and reduce the cost of manufacturing. This can be achieved by the use of compliant mechanisms and 3D printing. So, the objective of this thesis is to develop design approaches and models for prosthetic ankle joints using kinematic models of the human ankle and compliant mechanisms technology. Compliant mechanisms offer several potential design advantages over traditional rigid-body designs including high reliability and low cost. These design advantages are ideal for use in prosthetics and with 3D printing prosthetic legs can be manufactured at a lower cost with short production time, making them more affordable and accessible. Another benefit of 3D printed prosthetic legs is that amputees can choose various designs for their artificial limbs.

This experiment work was carried out to investigate the effect of concrete strength in terms of compressive strength for M25 and M30 concrete by adopting immersion curing, wet gunny bags curing and steam curing as per IS 10262 – 2009. Traditionally quality of concrete in construction work is calculated in terms of its 28 days compressive strength. This procedure requires 28 days of moist curing before testing which is too long a period to be of any value for either concrete construction control or applying timely corrective measures. What is essentially needed for assessing quality of controlled concrete is an acceptance test which can supply result within about 24 hrs. after casting. With the assistance of reliable test methods employing steam curing techniques it is now possible to test the compressive strength of concrete within a short period. The result of investigation demonstrate that superior strength is achieved by Immersion curing than the other two types of curing. But the strength achieved in steam curing within 6 hours is nearby to Immersion curing.

A Borehole instability problem contributes significantly to increase in non-productive time (NPT) and overall cost of the drilling. These problems can occur in a variety of forms including stuck pipe, loss circulation, hole enlargement, breakout. Borehole problems such as drill pipe sticking, hole collapse, breakout, ,caving and tight holes have been experienced during drilling of wells in an oil field in the Niger Delta. This work analyzed the major cause of wellbore instability in a field in the Niger Delta by using data from two wells drilled and proposes an optimum mud window for cost-effective and safe drilling operations. Geomechanical model was used to evaluate the in-situ stress and induced stresses with Mogi Coulomb and Mohr Coulomb failure criteria to predict the breakout profile and estimate the optimum mud weight to avoid sticking of the drill string.......

The word "Globalization‟ means International Integration (II). Globalization can greatly improve the role of agriculture as an engine of growth in low-income peoples‟ by making it possible for agriculture to grow considerably faster than domestic consumption. In the district, about 67% of the population still depend on agriculture for their livelihood, and out of 312,470 hectares of geographical areas of the district 272,564 hectares (i.e 87.23%) area is under cultivation (Census of India, 2011). Uttar Dinajpur Krishi Vigyan Kendra (UBKVK) is vested with the responsibilities to bring forth agricultural vis-a-vis rural development in the rural blocks through its mandated activities on the training of practicing farmers, rural youth and extension functionaries, front line demonstration, and on farm adaptive trials to enhance the total production of the district as well as self-employment generation........

''Dark box'' modeling combines the utilization of first-standard based ''white-box'' models and observational ''black-box'' models, offering specific advantages when: (a) there is an absence of principal theory to depict the system or process modeled; (b) there is a shortage of appropriate experimental data for validation or (c) there is a need to diminish the complexity of the model. The dark box approach has been utilized, for instance, to make numerical models to anticipate the time span of usability of chilled products or the thermal behavior of defectively blended fluids, or to make models that combine artificial neural networks and dynamic differential equations for control-related applications. The current paper highlights the structural dynamics creating grey box models.
