The psychrotrophic micro-fungi of soil of Jammu city, India, were studied. The fungal isolates were identified by morpho-taxonomically and screened for their ability to grow at low temperatures. Most of the predominant isolates were species of Mucor sp., Penicillium sp., Rhizopus sp., Aspergillus sp. and Fusarium sp. Isolated micro-fungi were characterized and screened in respective enzymatic agar medium for their degradation capability at 15°C. Penicillium sp., Fusarium sp., Alternaria sp. were found to be the maximum producer of cold active lipase, whereas Aspergillus sp. and Microsporum sp. showed maximum cellulase activity. The findings of this study indicate the possibility that the isolated strains produce novel extracellular enzymes that were active in cold temperature, which has immense application in many industries.

Excessive specialisation and production requirements place high demands on the metabolism of the broiler chicken. A number of metabolic problems, such as ascites, arise in chickens due to intensive selection to manifest their genetic potential for rapid growth. Ascites syndrome (Pulmonary Hypertension Syndrome) is one of the major causes of mortality and morbidity in modern broiler production today. Genetics, the environment, and management all seem to interact to produce a cascade of events that culminate in ascites syndrome. It is generally accepted that the high metabolic rate of current broiler lines causes an increased demand for oxygen, especially in cold environments or when birds are fed high nutrient density diets. In such situations, the relatively underdeveloped cardio-respiratory system of modern broilers fails to fulfil the required oxygen demand, which leads to hypoxemia, resulting in the development of pulmonary hypertension and subsequently ascites. Many nutritional, medicinal and management strategies have been proposed to alleviate the ascites. Higher levels of dietary vitamin C and E along with selenium might be beneficial, as they decrease the free radicals that are generated in birds with ascites. As the high metabolic rate (fast growth) is a major factor contributing to the susceptibility of broilers to ascites, appropriate selection strategies or feed restriction or light restriction in order to slow down the growth rate seem practically viable methods, since final body weight is not compromised. Optimisation of the house temperature and ventilation in cold weather seem helpful practices to decrease the incidence of ascites. © 2011 World's Poultry Science Association.

Rice is a staple food for over half of the world's population. Germinated brown rice (GBR) is considered whole food because only the outermost layer i.e. the hull of the rice kernel is removed which causes least damage to its nutritional value. Brown rice can be soaked in water at 30 °C for specified hours for germination to get GBR. Soaking for 3 h and sprouting for 21 h has been found to be optimum for getting the highest gamma-aminobutyric acid (GABA) content in GBR, which is the main reason behind the popularity of GBR. The intake of GBR instead of white rice ameliorates the hyperglycemia, boosts the immune system, lowers blood pressure, inhibits development of cancer cells and assists the treatment of anxiety disorders. Germination process could be used as enzymatic modification of starch that affects pasting properties of GBR flour. GBR would improve the bread quality when substituted for wheat flour. It is concluded that GBR has potential to become innovative rice by preserving all nutrients in the rice grain for human consumption in order to create the highest value from rice. © 2011 Association of Food Scientists & Technologists (India).

The coal based Direct Reduced Iron (DRI) route for secondary steel production is now a preferred choice in India. Steel making is invariably associated with emission of air pollutants into the environment. Air quality monitoring was carried out in Winter, Summer and Rainy seasons of 2008 in eight monitoring stations in the work zone and five stations in the residential zone of an Integrated Steel Industry located in Orissa state, India. Four air quality parameters i.e. SPM, RSPM, SO2 and NO2 were monitored. Mean SPM and RSPM values were found to be significantly high (p < 0.01) at stations nearer to source in both work zone and residential zone .The highest average SPM and RSPM values in the work zone recorded were 4869 microg/m3 and 1420 microg/m3 and in the residential zone 294 microg/m3 and 198 microg/m3 respectively. No significant difference in the SO2 and NO2 levels was observed between the work and residential zones. In general, the values of air pollutants were highest in Winter followed by Summer and Rainy season. SPM and RSPM values exceeded the National Air Quality Standards (NAAQS) in both the residential and work zones.

The Tevatron, where the top quark was discovered, and the currently functional Large Hadron Collider (LHC), with copiously produced top pairs, enable a detailed study of top-quark properties. In particular, they can be used to test the couplings of the top quark to gauge bosons. Several extensions of the standard model (SM) can give rise to anomalous couplings of the top quark to gauge bosons, in particular, the gluons. In this work we examine how top-quark polarization, which is predicted to be negligibly small in the SM, can be used to measure chromomagnetic and chromoelectric couplings of the top quark to gluons. We place special emphasis on the use of angular distributions and asymmetries of charged leptons arising from top decay as measures of top polarization and hence of these anomalous couplings. Sensitivities that may be reached at the Tevatron and the LHC are obtained. © 2013 American Physical Society.

Rice breeders have made a major contribution to increase production. With minimal resources, the conventional breeding program at the Orissa University of Technology (OUAT) has released more than 50 varieties since 1969, including some varieties that were released in other states or countries. The structure of this breeding program is described. The ideal plant breeder should have a sound theoretical knowledge of genetics and biometry, but must live in the field with his or her plants and inspect field trials on a daily basis, and really know the germplasm contained within the program. A good breeder must also be fully aware of farmers' needs. There is considerable potential to develop new higher yielding varieties by exploiting exotic germplasm, using more efficient breeding and selection techniques, and using methods to increase genetic variation. Some other priorities for future breeding-directed research and general advice to the next generation of plant breeders is described in the article. © Society for the Advancement of Breeding Research in Asia and Oceania (SABRAO) 2013.

A high energy ep collider, such as the proposed LHeC, possesses the unique facility of permitting direct measurement of the HWW coupling without contamination from the HZZ coupling. At such a machine, the fusion of two W bosons through the HWW vertex would give rise to typical charged current events accompanied by a Higgs boson. We demonstrate that azimuthal angle correlations between the observable charged current final states could then be a sensitive probe of the nature of the HWW vertex and hence of the CP properties of the Higgs boson. © 2012 American Physical Society.

Thirty six rice genotypes of three different maturity groups were treated with 500 ppm of streptomycin (SM) solution for 48 hrs to study the growth inhibiting and bleaching effects on them. Growth inhibiting and bleaching effects were expressed in terms of seedling growth inhibition and bleaching index, respectively. Growth inhibiting effect of streptomycin was the highest on mid-early genotypes followed by mid-late genotypes and the lowest on late maturing genotypes of rice. Bleaching effect was low on mid-early genotypes and higher on those of mid-late and late genotypes. Correlation study and 2 × 2 contingency classification method revealed that most of the rice genotypes having high seedling growth inhibition or high degree of bleaching were found to be high yielder. Results of the present study indicated that high SM-sensitivity of genotypes in terms of seedling growth inhibition index or bleaching index could be used as an indicator of high yield potential in rice.

Nanostructured zinc–copper mixed ferrite was synthesized using sol–gel method. Different compositions of ferrite, Zn(1–x)CuxFe2O4 (x=0.0, 0.25, 0.50, 0.75), characterized by XRD, reveal single phase inverse spinel in all the samples. With increasing copper content, the crystallite size increases. The surface morphology of all the samples, studied by SEM, shows porous structure of particles. The prepared samples were also analyzed by FT-IR and TEM. Catalytic activity of the samples was studied on lanthanum oxalate decomposition by thermogravimety. The rate constant k has the highest value with x=0.75 and 5% (mole fraction) of the catalyst and is attributed to high copper content, the mixed sites Cu2+−Fe + and/or Cu+−Fe2+ ion pairs besides the one component sites Cu2+−Cu+, Fe3+−Fe2+, as a result of mutual charge interaction. In other words, the increasing activity of mixed oxides is attributed to increase in the content of active sites via creation of new ion pairs. With increasing Zn content, particle size increases. Variation of catalytic activity of ferrite powders is due to the changes of the valence state of catalytically active components of the ferrites, which oxidizes the carbon monoxide released from lanthanum oxalate. © 2016 The Nonferrous Metals Society of China

This study was conducted to investigate the effect of temperature on hot-air drying kinetics of stone apple (Aegle marmelos correa) slices and to evaluate the best model predicting the drying kinetics along with the colour changes during drying. Stone apple slices were conditioned to remove the mucilaginous material followed by hot-air drying in single layer slices with thickness of 8 mm at different temperatures (40-70°C) in a forced convection dryer. In order to estimate and select the appropriate drying model, six different models which are semi-theoretical and/or empirical were applied to the experimental data and compared. The goodness of fit was determined using the coefficient of determination (R2), reduced chi square (Χ2), root mean square error (RMSE) and mean bias error (MBE). Among the models proposed, the semi-empirical logarithmic model was found to best explain thin layer drying behavior of the stone apple slices as compared to the other models over the experimental temperature range. By increasing the drying air temperature, the effective moisture diffusivity values increased from 3.7317E-10 m2/s at 40°C to 6.675E-10 m2/s. The activation energy was calculated using an exponential expression based on Arrhenius equation. The relationship between the drying rate constant and drying air temperature was also established which gave a polynomial relationship. Samples dried at lower temperature had better lightness (higher L* values) compared to those dried at higher temperature. However, the samples dried at 600C showed a significant overall deviation (δE*) in colour and may be considered as a limiting temperature for drying of stone apple slices. ©All Rights Reserved.
