    Recruitment means systematic process of searching for prospective employees and stimulating them to apply for job in an organisation. The study inquires the current trends of job opportunities for qualified LIS professionals in the area of library and information science by examining all job advertisement published in different online job portals. The data collected from different online job portals have been criticised to reflect the various aspects of LIS profession such as employer and designation wise distribution of jobs, essential and desirable qualifications and competencies for different type of job positions. The data collected have been explained through tables and figures. The finding show that the number of posts advertised is very less in number in comparison of number of fresh LIS graduates. Therefore the state and central government should provide more job opportunities for fresh LIS graduates, LIS professionals and for research scholars

    Some recent experimental studies show the invisibility of antiferromagnetic transition in the cases of manganites when their particle size is reduced to nanometer scale. In complete contrast to these cases, we have observed the signature of antiferromagnetic transition in the magnetocaloric properties of nanocrystalline La0.125_{0.125}Ca0.875_{0.875}MnO3_{3} of average particle size 70 and 60 nm similar to its polycrystalline bulk form. The system exhibit inverse magnetocaloric effect in its polycrystalline and nanocrystalline form. An extra ferromagnetic phase is stabilized at low temperature for the sample with particle size 60\sim 60 nm.Comment: 3 Figure

    Anaerobic sulphate reduction method has the potential for being effective and economically viable over conventional treatment methods for the treatment of sulphate rich wastewater such as acid mine drainage (AMD). However, a major challenge in anaerobic sulphate reduction is the diversion of a fraction of organic carbon towards methane production. Use of long chain fatty acids (LCFA) as a methanogenic inhibitor to enhance sulphate reduction has the potential for being economically attractive since it is easily available at low cost. The present study investigated the effect of linoleic acid (LA) and COD/SO42- ratio on anaerobic dissimilatory sulphate reduction in semi continuous suspended growth system at 37 oC. Without LA, sulphate reduction of 50% was observed at a COD/SO42- ratio of 0.75. Sulphate reduction increased with increasing LA concentrations and at 1000 mg/L, almost 100% sulphate reduction was achieved

    During the past few years, advances in mobile communication theory have enabled the development and deployment of different wireless technologies, complementary to each other. Hence, their integration can realize a unified wireless system that has the best features of the individual networks. Next-Generation Wireless Systems (NGWS) integrate different wireless systems, each of which is optimized for some specific services and coverage area to provide ubiquitous communications to the mobile users. In this paper, we propose to enhance the handoff performance of mobile IP in wireless IP networks by reducing the false handoff probability in the NGWS handoff management protocol. Based on the information of false handoff probability, we analyze its effect on mobile speed and handoff signaling delay.Comment: 16 Page

    This paper presents the application of the new method in the process of making the decisions on the scooters selection. The Fuzzy AHP method was used to obtain the weight coefficients of criteria, on the basis of which the alternatives were evaluated. The selection of criteria for evaluating scooters was based on an analysis of available manufacturer website. The evaluation and selection of scooters was carried out using a new multi-criteria decision making (MCDM) method. The present study tries to identify the attributes like kerb weight, mileage, top speed, fuel tank capacity and price playing prominent role in the buying behavior of the working women while purchasing scooters. Fuzzy-AHP method has been used to obtain the relative weights of the criteria, on the basis of which the alternatives are evaluated using new MCDM. The TOPSIS and MABAC methods were tested under the same conditions. The stability of the result obtained by this method is established through a sensitivity analysis

    Partial nitritation/anammox (PANAM) technologies have rapidly developed over the last decade, but still considerable amounts of energy are required for active aeration. In this study, a non-aerated two-stage PANAM process was investigated. In the first-stage upflow fixed-film bioreactor, nitratation could not be prevented at ammonium loading rates up to 186 mg N l-1 d-1 and low influent dissolved oxygen (0.1 mg O2 l-1). Yet, increasing the loading rate to 416 and 747 mg N l-1 d-1 by decreasing the hydraulic retention time to 8 and 5 h, respectively, resulted in partial nitritation with the desired nitrite to ammonium nitrogen ratio for the subsequent anammox stage (0.711.05). The second-stage anammox reactor was established with a synthetic feeding based on ammonium and nitrite. After establishing anammox at low biomass content (0.5 g VSS l-1), the anammox influent was switched to partial nitritation effluent at a loading rate of 71 mg N l-1 d-1, of which 78% was removed at the stoichiometrically expected nitrite to ammonium consumption ratios (1.19) and nitrate production to ammonium consumption ratio (0.24). The combined PANAM reactors were operated for 3 months at a stable performance. Overall, PANAM appeals economically, saving about 50% of the energy costs, as well as technically, given straightforward operational principles

    Iodine deficiency is endemic in West Bengal as evident from earlier studies. This community-based, cross-sectional descriptive study was conducted in North 24 Parganas district during August-November 2005 to assess the consumption of adequately-iodized salt and to ascertain the various factors that influence access to iodized salt. In total, 506 households selected using the multi-stage cluster-sampling technique and all 79 retail shops from where the study households buy salt were surveyed. The iodine content of salt was tested by spot iodine-testing kits. Seventy-three percent of the households consumed salt with adequate iodine content (≥15 ppm). Consumption of adequately-iodized salt was lower among rural residents [prevalence ratio (PR): 0.8, 95% confidence interval (CI) 0.7-0.9], Muslims (PR: 0.8, 95% CI 0.7-0.9), and households with monthly per-capita income of ≤US$ 10 (PR: 0.7, 95% CI 0.6-0.8). Those who heard and were aware of the risk of iodine-deficiency disorders and of the benefit of iodized salt were more likely to use appropriate salt (PR: 1.2, 95% CI 1.1-1.3). Those who were aware of the ban on non-iodized salt were more likely to consume adequately-iodized salt (PR: 1.1, 95% CI 1.01-1.3). The iodine content was higher in salt sold in sealed packets (PR: 2.9, 95% CI 1.8-4.8) and stored on shelves (PR: 1.6, 95% CI 1.3-2.0). Seventy-two percent of the salt samples from the retail shops had the iodine content of ≥15 ppm. The findings indicate that elimination of iodine deficiency will require targeting the vulnerable and poor population

    Food producing animals are the major reservoirs of Shiga-toxin producing (STEC) and enteropathogenic Escherichia coli (EPEC). The yak (Poephagus grunniens) is a unique multipurpose bovid, reared by highlanders in the Himalayan region. A total of 67 STEC, 5 EPEC and 22 ETEC strains were isolated from 256 rectal swabs of free ranging yaks from the West Kameng district of Arunachal Pradesh, India. Among the STEC isolates, shiga toxin producing genes stx2 was predominant, followed by stx1. Of all the stx variants, stx1c, stx2d, stx2c, stx2e and stx2f were detected in 23, 11, 2 and 1 isolates, respectively. Further, genes such as eaeA, ehxA, saa, iha and toxB were detected in 16, 35, 28, 10 and 2 isolates, respectively. One of the EPEC isolates possessed a bfpA gene and was categorized as typical EPEC. Among the ETEC isolates, genes such as LT, STa, STb, F41 and K99 were detected in 14, 5, 13, 2 and 2 isolates, respectively. The majority of the STEC, EPEC and ETEC isolates exhibited multi-drug resistance. The study revealed the presence of multi-drug resistant diarrhoea genic E. coli in free ranging yaks from the West Kameng district of Arunachal Pradesh. Moreover, the presence of STEC/EPEC can be a potential public health risk for tribal highlanders residing in close proximity of the reservoir yaks.Životinje koje služe za proizvodnju hrane mogu biti rezervoar šiga-toksigenih (STEC) i enteropatogenih (EPEC) sojeva bakterije Escherichia coli. Jak (Poephagus grunniens) je jedinstveni multipari bovid kojeg uzgajaju gorštaci na Himalaji. Ukupno je bilo izdvojeno 67 STEC sojeva, 5 EPEC sojeva i 22 ETEC soja iz 256 rektalnih obrisaka slobodno držanih jakova na području West Kameng, Arunachal Pradesh, Indija. Među izolatima STEC prevladavao je gen stx2 za prizvodnju šiga-toksina, a slijedio ga je gen stx1. Od svih varijanata gena stx, stx1c bio je dokazan u 23 izolata, stx2d u 11 izolata, stx2c u dva izolata, a stx2e i stx2f u jednog izolata. Nadalje gen eaeA dokazan je u 16 izolata, gen ehxA u 35, gen saa u 28, gen iha u 10 te gen toxBu dva izolata. Jedan od izolata EPEC posjedovao je gen bfpA i svrstan je u tipične EPEC izolate. Gen LT dokazan je u 14 ETEC izolata, gen Sta u pet, gen STb u 13, gen F41 u dva i K99 također u dva izolata. Većina izolata STEC, EPEC i ETEC pokazivala je otpornost na više lijekova. Istraživanje je pokazalo da postoji višestruka otpornost bakterije E. coli izdvojene iz slobodno držanih jakova s proljevom na području West Kameng, Arunachal Pradesh. Povrh toga, prisutnost STEC/EPEC može predstavljati rizik za javno zdravstvo za gorštačka plemena koja dolaze u bliski dodir s jakovima
