ABSTRACT Refractive index, density, specific refraction, iodine value, saponification value, molecular weight, relative density and absorption of oils have been calculated at room temperature for six samples of oils. The textures, UV absorption characteristics of these oils have also been studied. Some empirical relations between physical and chemical constants were fitted to the experimental data […]

Automated Age Prediction Using Geometric Features of Facial Im-ages and Neural Network
ABSTRACT Automated age estimation is an important processing task that serves many purposes such as surveillance monitoring, marketing of products, authentication systems, find out the fugitive or missing person and security control etc. Therefore, estimating age from still face images by using facial features is trending research topic from past few years. An automated age […]
Effect of Reinforcement on stability and Settlement ofEmbankment: A Finite Element analysis of Different Kinds of Reinforcing and Construction Conditions
ABSTRACT Due to less shear strength and high compressibility of soft soils, construction of soil embankment on these types of soils leads to problems such as big and non-uniform settlements. Nowadays, soil reinforcement is used as a trustable and efficient way for increasing soil strength and stability of it. Usage of geosynthetics for increasing height […]
Effect of Garment Size Ratio and Marker Width Variation on Marker Efficiency for both Manual and Computerized Marker
ABSTRACT Marker making is one of the crucial activities in cutting room. An efficient marker minimizes the fabric wastages during cutting. A good marker is indicated by its efficiency. The increasing in marker efficiency means the more fabric utilization because fabrics are cut following the guidelines of marker. In this study, 06 (six) markers (both […]
Black Carbon Incorporation Effect on Optical Properties of Poly-Methyl Methacrylate Films
ABSTRACT The optical properties of poly-methyl methacrylate (PMMA) films with difference filling levels of black carbon (BC) were studied in the visible and ultraviolent wavelength regions. It was found that the optical absorption is due to allowed- and, forbidden- direct transitions and the energy gaps decrease with increasing BC content for all transitions, while the […]
The Influence of Waste Crankcase Oil Blended Fuel Samples on Flame and Thermal Behaviour of Atomising Swirl Oil Burner
ABSTRACT The price volatilities of liquid hydrocarbon fuels in the international crude oil market, the consequent hike in energy cost, and environmental challenges resulting from the indiscriminate disposal of waste crankcase oils has necessitated the quest for alternative low cost energy option in Nigeria. This has prompted deliberate research efforts to recover energy from waste […]
Effects of Lime Stabilization on the pH Scales of Soils in Parts of KwaZulu Natal, South Africa
ABSTRACT In South Africa, the use of stabilizing agents in road construction has been in practice for some years. The province of KwaZulu Natal, in South Africa is currently undergoing some road rehabilitation projects with the investigation of properties of lime stabilized soil-the pH value being one of the necessities to understand the behavior of […]
New Trends in Solar Energy Modeling and Developing a Relation for Performance of Solar Radiation
ABSTRACT Solar photovoltaic system performance depends on environmental conditions. Solar photovoltaic panel is a power source having nonlinear internal resistance. As the intensity of light falling on the panel varies, its voltage as well as its internal resistance both varies.This paper presents a circuit-based simulation model for a PV cell in order to allow estimate […]
Corrosion Inhibition and Adsorption Properties of Soy Polymer Ex-tract of Glycine Mac-L On Mild Steel in Acidic Medium
ABSTRACT Soy polymer was extracted from soybean [Glycine Mac-L] and used in studying the corrosion inhibition of mild steel in 2 molar mass solution of hydrochloric acid and compared with the corrosion inhibition properties of poly [vinyl pyrrolidone] in the same acidic medium, using hydrogen evolution method at temperature range of 25-60OC and inhibitor concentration […]
Study of Various Pretreatment Methods for Tea Waste for the Re-moval of Nickel Ni (II) Ions from Synthetic Waste Water by Adsorp-tion
ABSTRACT The adsorption study was carried out to evaluate the effects of various pretreatments on tea waste (TW) for the removal of Ni (II) metal ions from synthetic waste water. The tea water was chemically treated with 0.1M different NaOH, Na2S, HCHO, KOH, Na2CO3, H2C2O4, HCL, H2S04, H3PO4, HNO3 solutions. It was observed that certain […]
