Abstract:
A geotechnical evaluation of some soils in Numan, Adamawa, North –East, Nigeria has been carried out. This was done to determine the suitability of the soils for use as sub-grade/filling, sub-base and base course materials for road construction. The samples were collected from five different areas, at surface and sub-surface levels. The areas are New Demsa, Farei, Dowaya, Numan Town and Imbru. The soil samples were subjected to laboratory investigations in conformity with the American Association of State Highway and Transportation (AASHTO) and the Bristish Standard Institution (BSI) Standard

In order to study the applicability and strengthening effect of impact compaction technology in wetness and softness loess roadbed treatment, impact compaction technology was applied in ground treatment and layered filling roadbed compact of a freeway sub-grade construction, and compactness and settlement of the soil were also measured. Test results suggest: impact compaction technology can effectively apply to shallow wetness and softness loess roadbed treatment and the most effective depth is about 80cm, and this effect appears to increase with the impact compaction times and 30 impact compa

Abstract:
A preliminary study of the baryte occurrence in the Tsareta-Tungan Kudaku area, Northwestern Nigeria shows that it is hosted by low- grade metamorphic rocks mainly Phyllites, in veins of about 1.5km wide and 4m deep. It is a fissure filling vein type deposited in fissures running parallel-sub parallel to the Anka fault system. The barytes has variable specific gravity ranging between 3.8 for surface occurrences and 4.3 at deeper levels. This quality meets the specification of specific gravity of 4.2 for use as drilling mud in the oil industry. Chemically, the baryte has BaSO<sub>4</sub> concen

Abstract:
Today, all over the World, soil plays major role in Civil Engineering works or construction. Its thorough assessment is impossible if its Engineering properties were overlooked. The aim of this study is to analyze some Engineering properties of lateritic soil deposited in Isan - Ekiti, South western Nigeria. Soil samples collected from the study area were subjected to Atterberg Limits, CBR and Grain Size laboratory tests. It is observed that the LL, PL, PI, SL and CBR values varied from varied from 41.10 to 57.50 , 24.60 to 35.50 , 14.80 to 22.70 , 0.32 to 0.61 and 4.38 to 30.21 respectively f

Abstract:
Continuous casting of steel is a process in which liquid steel is continuously solidified into semi-finished or finished product. In continuous casting, one of the major operational irregularities encountered is wrong cutting of slab (long or short) and grade mix of two different steel during casting of slab which leads to productivity loss, capital loss, and safety hazards etc. In the present work, a neural network model is developed to track the tundish filling and casting speed. The model is fully transient and consists of three sub models, which account for mixing in the tundish, mixing in

Abstract:
Quality of tooling surface has been considered as one of the important factors defining the injection molded part quality. Therefore, surface polishing has been an important and relatively expensive step in conventional mold making process. Although the poor surface quality impacts the product quality when molding macroscale parts, it becomes more significant with sub-micrometer features. Previous micro injection molding research result has indicated that rough tooling surface may cause polymer adhesion on the tooling surface. To evaluate the effect of roughness, optical grade polycarbonate wa
