The Erbium doped KDP crystals were grown by Sankaranarayanan-Ramasamy (SR) method with the vision to improve the properties of the crystal. The chemical composition of the grown crystals is confirmed by EDAX Analysis. The grown crystal was characterized by PXRD and UV-Vis analysis. The SHG efficiency is determined by Kurtz powder technique. The dielectric constant, dielectric loss and ac conductivity of the crystal were studied. The functional groups are identified by FT-Raman analysis. The Optical transmission and SHG studies shows the suitability of the ingot for optical applications.

Rice bran, one of the most abundant and valuable byproducts produced during the rice milling process, is of steadily growing interest in recent years due to its potential health benefits. Herein, we investigate and report the physicochemical properties of rice bran obtained from Mubi, Adamawa State, Nigeria. The rice bran was initially combusted and soil samples of the baked, unbaked soil and surrounding particular area where we carried out the combustion were collected and analyzed for its physicochemical properties. The results revealed that the baked soil has a higher concentration of calcium, magnesium, potassium and sodium than the unbaked soil. Furthermore, retention of water (tension) and the ability to absorb water (infiltration) was discovered to be higher in the baked soil sample. This shows that the heat of combustion of rice bran affects the physical, chemical and mechanical properties of soil in a peculiar way.

Green house experiment was conducted to explore the influence of different concentrations of Vermicompost in root–knot nematode management against Meloidogyne incognita infecting Cluster bean Cyamposis tetragonaloba. Vermicompost fortification treatment resulted in reduced nematode infection and increased growth characteristics such as shoot – root length and shoot – root weight. With the increase of concentration of Vermicompost corresponding increase noticed in growth characteristics of treated plants. Vermicompost fortified plants showed increment in sugar, protein and lipid over untreated control. Increment of these metabolites reflects treated plants were metabolically cope up the infection and promoting excessive plant growth.In vitro studies of hatching trials revealed significant reduction in larval emergence. The percent reduction of larval emergence showed a significant positive correlation with increased concentration of Vermicompost. Vermicompost treatment significantly affects the soil population of nematode which again reflects a dosage dependent phenomenon. Present investigation confirms Vermicompost as an excellent growth promoters and potential prophylactic agent.

Geophysical methods widely used in oil and gas exploration. Modeling of gravity data is used extensively to illustrate the geometry and interface between the sediments and bedrock. Which can help the salt dome, anticline folds, dome-shaped uplift of the continental platform and reef masses to be identified. There are various methods to illustrate the bedrock topography, and we will describe one of these methods in present paper. Using the upward continuation, we extract the residual gravity anomaly which in fact shows the local effect of bedrock gravity on the observed gravity. Then, according to the Oldenburg – Parker method, the residual gravity data are inversed and finally the 3D geometry the bedrock is illustrated. It should be noted that some software’s like Surfer and Excel are used in this research but the program main code is written using Matlab programming.

The first stage of the study consists of defining rock types by relating Geological framework, lithofacies, petrology to porosity, permeability, and Water saturation. Rock types represent reservoir units with a distinct porosity -permeability relationship and a unique water saturation range for a given height above the free water level. We also describe the conventional methodology used to evaluate water saturation from sections of the electric log of a well. The second stage of the work involved the analysis of the cored samples of the well (SANDS D 2, E1-8).Which will lead to the determination of the water saturation of the well. The third stage of the work dealt with the integration of the core analysis result with formation evaluation data to define reservoir water saturation. By using a proposed water saturation model, known as the molco water saturation model. It was observed that the conventional Archie water saturation gave the water saturation for the well section as 74.26% while the model gave it as 41.6%, giving a consolidated difference of 33.20%. This result will contribute to the understanding of tight reservoirs and making an impact on reservoir development.

A study was conducted to study the effect of integration of nitrogen sources on okra (Abelmoschus esculentus) grown in sandy regosols. Nitrogen sources farmyard manure, poultry manure, Amutha Karaisal and urea were applied on equal N basis at 135 kg Nha-1. Organic nitrogen (N) sources were used solely and in combination with urea at 50% N from each. And P2O5 and K2O were applied at the rate of 90 kg ha-1 by triple super phosphate and muriate of potash respectively. There were eight treatments replicated thrice. Among the treatments, yield was superior in 100% N supplied by poultry manure and next was followed by 50% N from farmyard manure + 50% N from Urea. The influence of AmuthaKaraisal was inferior in yield than other manures. There was no significant difference in average length of pod, but there was significant difference in average number and fresh weight of pod.

Glycine family crystals are very useful materials for electronics and many optical applications. In present work single crystals of pure and ADP-, KDP- (0.2 mol) doped Triglycine sulpho zinc chloride (TGSZC) crystals are grown by solution growth method. Grown crystals are characterized by UV-Vis, IR and Raman spectral studies. From UV –Vis spectra optical quality of all crystals is determined. From IR and Raman spectra characteristic vibrations are identified. Powder XRD study reveals the Crystal structure of grown crystals. Ferroelectric nature of all crystals is tested using homemade Sawyer-Tower circuit. Electrical conductivity measurements are carried out for pure and doped TGSZC crystals.

Lymphoepithelioma-like carcinoma is an undifferentiated carcinoma with histological features similar to undifferentiated, non-keratinizing carcinoma of the nasopharynx. Lymphoepithelioma-like carcinoma of the urinary bladder is uncommon with a reported incidence of 0.4%- 1.3% of all bladder cancer. We report a case of a 68 year-old-man with a muscle-invasive lymphoepithelioma-like carcinoma of the bladder who was treated with radical cystectomy with 12 months follow up.

The levels of minerals and fatty acids in Clarias gariepinus, Channa striatus and Tilapia zillii were determined using standard analytical techniques. Results showed high levels of most of the minerals especially sodium 49.9-84.6 mg/100g and potassium 67.5-93.2mg/100g. The zinc contents (21.3-36.4 mg/100g) were above the recommended daily allowance (RDA) whereas, the iron levels (10.5-18.4mg/100g) fell within the range of 10-15mg, 18mg and 12mg requirements for children, women and men respectively. The most concentrated saturated fatty acid in the samples was palmitic acid (22.3 – 23.5%) and it was equally the most concentrated of all the fatty acids determined. The total saturated fatty acid (SFA) ranged between 35.0 – 38.1%. The monounsaturated fatty acid (MUFA) ranged between 38.3-39.4% whereas, polyunsaturated fatty acid (PUFA) ranged between 22.5-26.1%. Total unsaturated fatty acid (MUFA + PUFA) range was 61.9 – 64.9%. MUFA/SFA range was 1.03 – 1.11 whereas PUFA / SFA ranged between 0.59 - 0.75. This range is reasonable enough to discourage the development of atherosclerosis. The n-6 / n-3 ratios in C. striatus (7.75) and T. zillii (5.78) compare favourably with the recommended range of 5-10 whereas, that of C. gariepinus (274) was much higher.
