Ngari is a non-salted fermented fish product of Manipur. Sundried Puntius sophore (Ham.) are fermented anaerobically with no intentional addition of starter culture for 4 to 12 months. LAB, Bacillus and yeast were involved in its fermentation. They are prepared at household level and marketed locally. Ngari are good source of protein, amino acids and minerals. The product has potential probiotic properties, antioxidant and antihypertensive characteristics. However, the fermented product if not processed hygienically can pose threat to food borne illness due to cross contamination. This review study is to know the processing technique and potential health benefits of Ngari.

Exchange rate exposure of UK listed oil and gas companies was examined against four major currencies; Australian dollar, Canadian dollar, Euro and US dollar by applying Adler and Dumas (1984) estimation model. The final sample of the study consists of (17) firms. (100%) of the sample firms exhibit significant negative exposure to US dollar indicating a decrease in stock returns of these firms, all the companies’ exhibit significant positive exposure to Australian dollar, 88% of the sample firms exhibits significant positive exposure to Canadian dollar. Major findings from the study reveals that oil and gas sector in UK is highly vulnerable to exchange rate risk particularly against US, Australian and Canadian dollar.

India has an age old unbroken history of welcoming and providing warm hospitality to an endless inundation of men and women of diverse creeds, cultures and races. However, when it comes to its own citizens who are displaced due to conflicts, the situation is entirely different and awfully pathetic. The IDPs of Bodoland are facing the same. They are devoid of basic rights and amenities. In the absence of a comprehensive law pertaining to protection and rehabilitation of conflict induced IDPs, their problems have been aggravated. In view of the forgoing a study of the genesis of Bodoland, history of ethnic conflicts in Bodoland, condition of the IDPs created by these conflicts and legal response to the needs of these IDPs has assumed paramount importance. This paper aims to shed light on these not so talked about problems of the people of Bodoland and also makes a humble attempt advancing a few suggestions towards remedying the same.

The present study was undertaken to examine the influence of School related Hardiness and Achievement Motivation on Academic Achievement of Secondary School students. Descriptive survey method was employed to conduct it. Statistical techniques of product moment method of correlation and analysis of variance were employed to analyse data. There was no significant relationship found between Academic Achievement and school related Hardiness but a significant relationship was found between Academic Achievement and Achievement Motivation. Significant main effect of Achievement Motivation was revealed on the Academic Achievement of students at .05 level but there was no significant main effect of school related Hardiness on Academic Achievement. Results also indicated statistically significant interaction at .05 level between school related Hardiness and Achievement Motivation with regard to Academic Achievement. Overall, these findings provide new insights about a comprehensive understanding of School related Hardiness and Achievement Motivation as correlates of Academic Achievement.

In today’s era, majority of the residential construction involves masonry. Despite its wide use in structural engineering, masonry is still the least understood especially seismic behavior building material in terms of strength and deformation characteristics due to its heterogeneity. The general behavior of unreinforced masonry under lateral is brittle and thus has high seismic hazard. Confining masonry is found to enhance the seismic behavior of masonry. In this project simple masonry (unreinforced masonry) and confined masonry walls of size 1.25mx1.25mx.1m were tested and compared for their behavior under in plane lateral loads. Confinement to the masonry was provided in the form of reinforced vertical columns and horizontal beam called as tie columns and tie beam respectively. The reinforcement in confinement was provided as per the guidelines issued by Euro code 8 for confined masonry. Their ultimate load strength, deformation capacity (ductility) and initial stiffness are the parameters studied in comparison. Confined masonry showed excellent behavior under lateral loads both in terms of ultimate load capacity and ductility than the simple masonry.

About 1% of the total storage capacity in the world’s reservoirs is lost annually due to sedimentation. Sediments can also block intakes in reservoirs and damage tunnels or turbines. One of the most effective techniques to remove these sediments is flushing, whereby water level is lowered sufficiently to re-erode deposits and flush them through the intakes. Outflow sediment discharge may well be related to the parameters such as the sediment characteristics in the reservoir, sediment discharge and hydrological conditions. In this paper, investigation and evaluation of sedimentation and flushing in Dez1 stream dam are considered. Sensitivity analysis of the mathematical model is evaluated for input parameters variation on sedimentation and flushing in reservoirs. Results shows that the rate of sediment flushing is strongly associate with grain size of sediment. This paper shows that flushing can retrieve about 50% of beneficial storage of reservoirs.

Solvent extracts of xerophytic plant, Opuntia dillenii Haw were screened for larvicidal, ovicidal and repellent properties against the dengue vector Ae. aegypti L. Five different extracts viz., hexane, petroleum ether, ethyl acetate, carbon tetrachloride and distilled water were tested for larvicidal, ovicidal activity in five different concentrations ranging from 62.5, 125, 250, 500 and 1000 ppm. Among the five solvent extracts of O. dillenii, petroleum ether extract showed the highest larvicidal activity at 1000 ppm against the fourth instar larvae of Ae. aegypti. The LC50 and LC90 values of O. dillenii petroleum ether extract were recorded as 323.76 and 829.76 ppm against Ae. aegypti larvae respectively. High ovicidal activity of 64% was recorded at 1000ppm concentration of petroleum ether extract. The petroleum ether extract was also found to be the most effective protectant against the adult female mosquitoes of Ae. aegypti. The mean protection time recorded in petroleum ether extract was up to 107 min at 5 mg/cm2 dosage against Ae. aegypti adults. The potential of petroleum ether extract of O. dillenii could be used in dengue vector control.

We report three cases of abdominal fibromatosis that caused hydronephrosis by extrinsic ureteral compression in young women with a fruitlessly surgical resection. This ureteral compression was treated by endoscopic placing of double pigtail stents or percutaneous nephrostomy associated with tamoxifen with, apparently, stabilization of the disease. All three patients were regularly monitored with change of the ureteral stents.

An analysis is presented for the problem of the fully developed natural convection magnetohydrodynamics micropolar fluid flow of heat and mass transfer in a vertical channel. Asymmetric temperature and convection boundary conditions are applied to the walls of the channel. The cases of double diffusion and Soret-induced connections are both considered. Solutions of the coupled non-linear governing equations are obtained for different values of the buoyancy ratio and various material parameters of the micropolar fluid and magnetic parameters. The resulting non dimensional boundary value problem is solved by the Galerken Finite element method using MATLAB Software. Influence of the governing parameters on the fluid flow as well as heat and solute transfers is demonstrated to be significant.
