Abstract
In India, to increase tuberculosis (TB) case detection under the National Tuberculosis Programme, active case finding (ACF) was implemented by the Global Fund-supported Project Axshya, among high-risk groups in 300 districts. Between April 2013 and December 2014, 4.9 million households covering ~20 million people were visited. Of 350 047 presumptive pulmonary TB cases (cough of ⩾2 weeks) identified, 187 586 (54%) underwent sputum smear examination and 14 447 (8%) were found to be smear-positive. ACF resulted in the detection of a large number of persons with presumptive pulmonary TB and smear-positive TB. Ensuring sputum examination of all those with presumptive TB was a major challenge.

Abstract
We report the first observation of the decays B^{0}→pΛ[over ¯]D^{(*)-}. The data sample of 711 fb^{-1} used in this analysis corresponds to 772×10^{6} BB[over ¯] pairs, collected at the ϒ(4S) resonance by the Belle detector at the KEKB asymmetric-energy e^{+}e^{-} collider. We observe 19.8σ and 10.8σ excesses of events for the two decay modes and measure the branching fractions of B^{0}→pΛ[over ¯]D^{-} and B^{0}→pΛ[over ¯]D^{*-} to be (25.1±2.6±3.5)×10^{-6} and (33.6±6.3±4.4)×10^{-6}, respectively, where the first uncertainties are statistical and the second are systematic. These results are not compatible with the predictions based on the generalized factorization approach. In addition, a threshold enhancement in the dibaryon (pΛ[over ¯]) system is observed, consistent with that observed in similar B decays.

Abstract
To understand the molecular mechanisms underlying the ability of the bacteria to survive at high temperature, gene expression profile of Brevibacillusborstelensis at 55°C during 5 and 10min heat shock period was carried out by high-throughput sequencing technology. A total of 2555 non-redundant transcripts were annotated. A total of 575 genes at 5min and 400 genes at 10min exhibited significant differential expression in response to temperature upshift from 50 to 55°C. Genes up-regulated under heat shock were associated with metabolism (mtnE), membrane transport, signal transduction, transcriptional regulation (ycxD, codY) and folding and sorting (hsp90). A larger number of genes encoding hypothetical proteins were identified. RT-PCR experimental results carried out on genes expressed under heat shock were found to be consistent with transcriptome data. The results enhance our understanding of adaptation strategy of thermophilic bacteria thereby providing a strong background for in depth research in thermophiles.

Abstract
Data from surveys on knowledge, attitudes and practice (KAP) on tuberculosis (TB) conducted under the Axshya project at two time points (baseline 2010-2011 and mid-line 2012-2013) were analysed for changes in coverage and equity of TB awareness after project interventions. Overall coverage increased from 84% at baseline to 88% at midline (5% increase, P < 0.05). In comparison to baseline results, coverage at the midline survey had significantly increased, from 81% to 87% among the rural population, from 81% to 86% among women, from 73% to 85% in the ⩾55 years age group, from 71% to 80% among illiterates and from 73% to 81% in the south zone (P < 0.05). The equity gap among the different study groups (settlement, sex, age, education and zones) decreased from 6-23% at baseline to 3-11% during the midline survey. The maximum decline was observed for type of settlement (rural vs. urban), from 10% to 3% (P < 0.05). This community-driven TB control project has achieved high and equitable coverage of TB awareness, offering valuable lessons for the global community.

Abstract
The genus Bacillus comprises of a diverse group with a wide range of nutritional requirements and physiological and metabolic diversity. Their role in nutrient cycle is well documented. 16S rDNA sequences do not always allow the species to be discriminated. In this study 40 Bacillus spp. obtained from fish culture pond and 10 culture type strains were analysed for their genomic diversity by PCR-RFLP of intergenic spacer region of 16S-23S and HSP60 genes. TaqI digestion of PCR products amplified by ITS PCR did not render distinctive RFLP patterns. Numerical analysis of ITS PCR-RFLP pattern differentiated the isolates into 11 clusters. Same species were found to be grouped in different clusters. But PstI digested PCR products amplified from HSP60 gene of the isolates showed distinctive RFLP patterns. The dendrogram constructed from HSP60 PCR-RFLP delineated the isolates into 11 clusters also. All the clusters, except cluster I grouped only one type of species. The results showed that Bacillus spp. could be clearly distinguished by PCR-RFLP of HSP60 gene. Therefore, the HSP60 gene is proposed as an additional molecular marker for discrimination of Bacillus group.

Abstract
Integrated rice-fish culture, an age-old farming system, is a technology which could produce rice and fish sustainably at a time by optimizing scarce resource use through complementary use of land and water. An understanding of microbial processes is important for the management of farming systems as soil microbes are the living part of soil organic matter and play critical roles in soil C and N cycling and ecosystem functioning of farming system. Rice-based integrated farming system model for small and marginal farmers was established in 2001 at Central Rice Research Institute, Cuttack, Odisha. The different enterprises of farming system were rice-fish, fish-fingerlings, fruits, vegetables, rice-fish refuge, and agroforestry. This study was conducted with the objective to assess the soil physicochemical properties, microbial population, carbon and nitrogen fractions, soil enzymatic activity, and productivity of different enterprises. The effect of enterprises induced significant changes in the chemical composition and organic matter which in turn influenced the activities of enzymes (urease, acid, and alkaline phosphatase) involved in the C, N, and P cycles. The different enterprises of long-term rice-based farming system caused significant variations in nutrient content of soil, which was higher in rice-fish refuge followed by rice-fish enterprise. Highest microbial populations and enzymatic properties were recorded in rice-fish refuge system because of waterlogging and reduced condition prolonged in this system leading to less decomposition of organic matter. The maximum alkaline phosphatase, urease, and FDA were observed in rice-fish enterprise. However, highest acid phosphatase and dehydrogenase activity were obtained in vegetable enterprise and fish-fingerlings enterprise, respectively.

Abstract
Fly ash (FA), a byproduct of coal combustion in thermal power plants, has been considered as a problematic solid waste and its safe disposal is a cause of concern. Several studies proposed that FA can be used as a soil additive; however its effect on microbial response, soil enzymatic activities and heavy metal accumulation in soil and grain of rice (cv. Naveen) to fly ash (FA) application was studied in a pot experiment during dry season 2011 in an Inceptisol. Fly ash was applied at a rate of zero per cent (FS), five per cent (FA5), ten per cent (FA10), twenty per cent (FA20), 40 per cent (FA40) and 100 per cent (FA100) on soil volume basis with nitrogen (N), phosphorus (P) and potassium (K) (40:20:20mg N:P:Kkg(-1) soil) with six replications. Heavy metals contents in soil and plant parts were analysed after harvest of crop. On the other hand, microbial population and soil enzymatic activities were analysed at panicle initiation stage (PI, 65 days after transplanting) of rice. There was no significant change in the concentration of zinc (Zn), iron (Fe), copper (Cu), manganese (Mn), cadmium (Cd) and chromium (Cr) with application of fly ash up to FA10. However, at FA100 there was significant increase of all metals concentration in soil than other treatments. Microorganisms differed in their response to the rate of FA application. Population of both fungi and actinomycetes decreased with the application of fly ash, while aerobic heterotrophic bacterial population did not change significantly up to FA40. On the other hand, total microbial activity measured in terms of Fluorescein diacetate (FDA) assay, and denitrifiers showed an increased trend up to FA40. However, activities of both alkaline and acid phosphatase were decreased with the application of FA. Application of FA at lower levels (ten to twenty per cent on soil volume basis) in soil enhanced micronutrients content, microbial activities and crop yield.

Abstract
A bio-based epoxy monomer was synthesized by acrylation of epoxidized castor oil (ECO). Subsequently, acrylated ECO (AECO)-toughened diglycidyl ether of bisphenol A (DGEBA) nanocomposites were prepared via sol–gel process with the addition of organically treated montmorillonite nanoclays. In this study, the curing kinetics of anhydride-cured DGEBA/AECO monomer with and without clays was studied by non-isothermal differential scanning calorimetry analysis. The apparent activation energy obtained by Flynn–Wall–Ozawa method was reduced from 63 to 59 kJ mol−1 and 69 to 61 kJ mol−1, respectively, with the addition of 1 wt% clay to the DGEBA/10 wt% AECO and DGEBA/20 wt% AECO systems, respectively. The two-parameter Šesták–Berggren autocatalytic model was used to obtain the reaction orders m and n, respectively. The curves obtained by the Málek method show good agreement with the experimental data for bio-based epoxy systems.

Abstract
Flooding is one of the major harmful abiotic stresses in the low lying areas of Asia and crop losses due to submergence are considerably high. Along with plant breeding techniques, agronomic management options in general and nutrient management in particular should be taken into consideration. Response of Sub 1 and non-Sub1 cultivars of rice to post-flood nitrogen (N) management under variable flood water was compared at maximum tillering stage. Submergence tolerance on survival, leaf senescence, metabolic changes, and anti-oxidant enzymatic activities were evaluated. Sub1 cultivars proved their superiority over IR-20 in terms of significantly higher survival, anti-oxidant enzymes and lower metabolic changes. Turbid water resulted in lower survival because of poor light transmission, chlorophyll retention and silt deposition. Basal phosphorus reduced the elongation, senescence and ethylene accumulation. Post-flood foliar spray of urea substantially increased the chlorophyll, soluble sugars and extenuated ethylene accumulation resulting in significantly higher survival. These nutrient management options can provide opportunities for better survival and productivity even under turbid water, helping farmers to cope with the existing problems in flood-prone areas.

Abstract
Tubercular brain abscess is a rare manifestation of neurotuberculosis. Large brain absceses are usually surgically treated. We report a case of tubercular brain abscesses in left cerebellar hemisphere and right parietal lobe in a child who was treated surgically for the cerebellar abscess and conservatively with antitubercular drug for parietal abscess. The patient showed significant clinical improvement and healing of brain abscess on follow up imaging. The resolution of relatively large abscess by conservative management with antitubercular treatment is very rare.

Abstract
A polymerase chain reaction (PCR) assay was developed for discrimination of Bacillus subtilis from other members of B. subtilis group as well as rapid identification from environmental samples. Primers ENIF and EN1R from endoglucanase gene were used to amplify a1311 bp DNA fragment. The specificity of the primers was tested with seven reference strains and 28 locally isolated strains of endoglucanase positive Bacillus species. The PCR product was only produced from B. subtilis. The results demonstrated high specificity of two oligonucleotides for B. subtilis. This species-specific PCR method provides a quick, simple, powerful and reliable alternative to conventional methods in the detection and identification of B. subtilis. To our knowledge this is the first report of a B. subtilis specific primer set.

An experiment was conducted to assess the effect of fly ash deposition without and with (0.25, 0.50, 1.0 and 1.5 g m(-2 )day(-1)) foliar dusting on the photosynthesis, stomatal conductance, transpiration, leaf temperature, albedo and productivity of rice. Dusting of 0.5 g m(-2 )day(-1) fly ash and above significantly reduced the photosynthesis, stomatal conductance, transpiration and albedo. Panicle initiation and flowering stages were more influenced by the fly ash deposition as compared to active tillering stage. At higher rates of fly ash deposition, all growth and yield parameters were significantly influenced due to increased heat load and reduced intercellular CO2 concentration. A significant reduction of 12.3, 15.7 and 20.2 % in grain yield was recorded over control when fly ash was dusted at 0.5, 1.0 and 1.5 g m(-2 )day(-1), respectively.

Abstract
Klebsiella pneumoniae being ubiquitous in nature encounters wide differences in environmental condition. The organism's abundance in natural water reservoirs exposed to temperature variation forms the basis of its persistence and spread in the soil and other farm produce. In order to investigate the effect of temperature changes on the survival and adaptation of the bacteria, the transcriptional response of K. pneumoniae subjected to low (20 °C) and high (50 °C) temperature shock were executed using Applied Biosystems SOLiD platform. Approximately, 33 and 34% of protein coding genes expressed in response to 20 and 50 °C, respectively, displayed significant up- or downregulation (p < 0.01). Most of the significantly expressed transcripts mapped to metabolism, membrane transport, and cell motility were downregulated at 50 °C, except for protein folding, sorting, and degradation, suggesting that heat stress causes general downregulation of gene expression together with induction of heat shock proteins. While at 20 °C, the transcripts of carbohydrate, lipid, and amino acid metabolism were highly upregulated. Hypothetical proteins as well as canonical heat and cold shock proteins, viz. grpE, clpX, recA, and deaD were upregulated commonly in response to 20 and 50 °C. Significant upregulation of genes encoding ribosomal proteins at 20 and 50 °C possibly suggest their role in the survival of K. pneumoniae cells under low- and high-temperature stress.
