In the present work a comparative study of the photochemical behaviour (steady-state photolysis) of oxalatopentaamminecobalt (III) perchlorate, [Co(NH3)5HC2O4](ClO4)2, in pure aqueous as well as in premicellar and micellar solutions of three different (anionic, cationic and non-ionic) surfactants has been undertaken. The photochemical reactivity of the complex has been found to charge in the following respects. (1) The photoaquation of ammonia does not take place in micellar solutions of all the three surfactants used. (2) The quantum yield of Co2+(ΦCo2+) changes as the concentration of surfactant changes with a concomitant change in the structure of the solution. The manner in which ΦCo2+ varies depends on the nature of the surfactant. The CMC of a surfactant can be determined from the plot of ΦCo2+ vs. -log [Surfactant]. (3) The effect of [CH3COO-] variation on ΦCo2+ is more prominent in micellar solutions.

The kinetics of phosphate sorption/desorption in eight acidic soils were studied. The data were fitted to a modified Freundlich-type of kinetic equation and the modified Elovich equation to yield several kinetic parameters. The kinetic experiments were conducted at 35 ± 1°C and for some soil, also at 45 ± 1°C. The phosphate sorption rate coefficients and the Elovich kinetic parameters were in agreement with the trend of phosphate sorption equilibrium behaviour of the present soils. The phosphate sorption kinetic parameters showed significant correlations with soil organic matter and oxalate-extractable aluminium and iron of the soils. The possibility that an association of organic matter in acidic soils with the hydrous sesquioxides of iron and aluminium leads to the formation of chelate complexes having large active surface area for phosphate sorption has been considered for the present soils. The sorption rate coefficients increased with temperature, in agreement with the simple Arrhenius behaviour. The activation energies for phosphate sorption suggested the chemical nature of the given sorption process.
During desorption, the sorption rate parameter was lower than that during the corresponding sorption run, indicating the possibility that the sorted phosphate might have undergone transformations that render it less susceptible to release.

Long-term monthly rainfall observations (1986-2014) were analysed for 12 rain-gauge stations installed at variable altitudes of Mizoram. Our objective was to assess the temporal change in the standardized precipitation index (SPI) values at different timescales using Mann-Kendall trend tests. Significant reductions in post-monsoon and winter rainfall were recorded for most of the sites. Increasing dryness during the winter months may intensify the acute water shortage in Mizoram. Our results emphasize the altitudinal insensitivity of mean monthly rainfall trend and prove the urgent need for adopting suitable water management practices to cope with the water scarcity problem to increase the resiliency of rabi agriculture in Mizoram in near future.Keywords

Background:Escherichia coli (E.coli) is most common organism responsible for UTI because of its various virulence factors to break the inertia of mucosal barrier. Objective: In this present study we aimed to access the different virulence factors and their correlation with multi-drug resistance.Materials and Methods: This was a prospective study done at Burdwan Medical College and Hospital, West Bengal. A total 100 urine samples from clinically suspected UTI patients were processed by standard microbiological procedures. Fifty (50) E.coli were isolated on MacConkey agar showing significant bacteriuria from the 100 samples studied. The virulence factors studied were Haemolysis, Bio-flim formation, Mannose sensitive/resistant haemagglutination, serum resistance and antibiotic resistance pattern. For bio-film three methods - congored agar, tube method and tissue culture plate method were compared. Haemolysis was observed on sandwich blood agar. Mannose resistance and sensitive haemagglutination and serum resistance were determined by standard methods. ESBL and MBL were detected by double disc diffusion method along with conventional antibiogram.
Result: Fifty E.coli were isolated from 100 urine sample in this study. Among these 30% showing haemolytic properties, 48% showing HA and 16% showing serum resistance. Three different methods of bio-film formation were evaluated. Antibiogram was plotted with MDR.
Conclusion: There is a need of periodic survillence, antibiotic policy, careful use of empirical and target antibiotics, use of antibiotic coated catheter, standard guidelines on care of catheter. This will reduce incidence, chronicity and recurrence of Urinary Tract Infections.

A total of 878 numbers of Indian major carps were investigated for studying the diversity of intestinal helminth parasites for a period of 1 year. The study revealed the presence of four different groups of helminthes, such as, digeneans, nematodes, cestodes and acanthocephalans. Among these groups nematodes dominate over others. L rohita was found to be infected more compared to other species of carps. Monsoon season was found to be congenial for proliferation of these parasites.Keywords

Natural biodiversity for functional and nutritional quality traits is of prime importance in breeding programmes for developing nutritionally rich genotypes. The present investigation was carried out to identify lines of sweet pepper with high ascorbic acid content and important mineral nutrients like potassium, phosphorus, zinc, copper, iron and manganese. Forty accessions of sweet pepper (Capsicum annuum L.) were analyzed for their functional and nutritional composition. Wide variation was observed in functional quality traits like ascorbic acid content (22-129mg 100g-1), and β-Carotene (0.39-1.0mg 100g-1) suggesting a considerable level of genetic diversity. Wide variability was also noticed for nutritional composition (K, P, Zn, Cu, Fe&Mn) in the tested lines. Across accessions, concentration of ascorbic acid was negatively correlated with copper content (r = -0.293, p < 0.05) being significantly greater in two accessions, VHC 34 and VHC 37 (129 and 118.0 mg100g-1, respectively) compared to other accessions. β-Carotene concentration was higher (0.85 to 0.99mg 100g-1) in six accessions, and lower (0.39 to 0.54mg 100g-1) in twenty four accessions. Greater variability present for quality traits holds an immense potential to help develop Capsicum lines with traits of high functional and nutritional quality. Therefore, this information is potentially useful in sweet pepper breeding programmes in the future.Keywords

The purpose of the study was to develop a floating control drug delivery system of ranitidine hydrochloride and investigate the effect of formulation variables on drug release profile and floating property. Ranitidine hydrochloride (RHCl) was used as a model drug because of its short biological half life and site of release at stomach. Tablets were formulated using different concentration hydroxypropyl methyl cellulose K4M, carbopol 934.where Sodium bicarbonate and Citric acid used as a gas generating agent. The floating behavior and in-vitro dissolution studies are carried out in a USP type II apparatus in 0.1 (N) HCL. It was observed that all the prepared formulation shows good floating capabilities up to 15 to 18 hours and slow steady release profile up to 12 hours. The dissolution profiles were subjected various kinetic release equations and found that drug release from different polymeric matrix follows diffusion controlled process. It has been also observed that combination of HPMC K4M and carbopol 934 shows better results as compared to their single use.Keywords

To achieve higher productivity, improved accuracy and to keep pace with rapid advancement in technology and manufacturing systems it is not enough to design the machine tool from static consideration only but the dynamic behaviour of the machine tool should also be taken into consideration appropriately. The relative vibratory movement between cutting tool and the work piece effects unsatisfactory performance of the machining process. Like in any other machine tools, vibration in cylindrical grinding machine is supposedly Influenced by parameters of the process, which has not been investigated so far to a fair extent. In the present work some aspects of dynamic performance of cylindrical grinding machine have been experimented, and results thereof analyzed, with special emphasis on parameter: in-feed.- Meta-Analysis of Classical Swine Fever Prevalence in Pigs in India:A 5-Year Study

Aim: The aim of the study was to determine the overall prevalence of classical swine fever (CSF) in pigs in India, through a systematic review and meta-analysis of published data.
Materials and Methods: Consortium for e-Resources in Agriculture, India, Google Scholar, PubMed, annual reports of All India Coordinated Research Project on Animal Disease Monitoring and Surveillance,and All India Animal Disease database of NIVEDI (NADRES) were used for searching and retrieval of CSF prevalence data (seroprevalence, virus antigen, and virus nucleic acid detection) in India using a search strategy combining keywords and related database-specific subject terms from January 2011 to December 2015 in English only.
Results: A total of 22 data reports containing 6,158 samples size from 18 states of India were used for the quantitative synthesis, and overall 37% (95% confidence interval [CI]=0.24, 0.51) CSF prevalence in India was estimated. The data were classified into 4 different geographical zones of the country: 20% (95% CI=0.05, 0.55), 31% (95% CI=0.18, 0.47), 55% (95% CI=0.32, 0.76), and 34% (95% CI=0.14, 0.62). CSF prevalence was estimated in northern, eastern, western, and southern regions, respectively.
Conclusion: This study indicates that overall prevalence of CSF in India is much lower than individual published reports.

Tree bean, Parkia timoriana is one of the most important perennial tree legume vegetable crops in north eastern region (NER) of India. Recently, sudden death or decline is emerging as a major constraint in the production of tree bean. The prevalence, intensity and etiology of this disease have not been extensively studied. The present work was aimed at studying the symptomology, severity and etiology of sudden death or decline of tree bean in the north eastern region of India. Typical symptoms of tree bean decline were initiated with wilting of half portion of the tree, excessive shedding of leaves, gradual drying up leading to death, and secondary infestation by insects on dead trees. The highest disease severity of 68.5% was observed in warmer regions like Kolasib, Mizoram. During survey, small bark borer was recorded in all districts and levels of infestation rate (holes/ft2 of log) reached maximum up to 25.49 in Hnanthial of Lunglei district. Young trees in the range 1–10 years with 57.32% (917 trees) of total trees (1600) infected were most susceptible to the disease compared to 12.58% (201 trees) infection in old trees in the range 21–30 years. The frequently associated pathogen with sudden death or decline of tree bean was identified as Botrydiplodia theobromae at the Indian Type Culture Collection, ICAR-IARI, New Delhi. It was the most aggressive species and proven to be pathogenic to tree bean following artificial inoculation.Keywords

A terotechnological approach to the analysis of any system is a cost effective performance evaluation over the life-cycle of the system. Thus it considers (I) the initial capital cost, (ii) the operating, maintenance, and repair costs, and (iii) the worth of lost production due to breakdown, frequent maintenance, and substandard performance. In a solar hot water system, the fuel cost being nil, an appropriate terotechnological approach would naturally emphasise on the selection of proper materials. Installation procedure, and maintenance schedule such that the system functions at its rated capacity during its design-life would not be affected by external environmental factors. It is attempted here to consider the different sub' systems and components, the initial and future costs, system sizing, installation procedure and maintenance schedule of a solar hot water system to achieve optimum life-cycle cost of the systemReferences
