Isolation of seed-borne fungi of sorghum (Sorghum vulgare pers.)

Sorghum (Sorghum vulgare Pers.) is the fifth most important cereal crop in the world after wheat, rice, maize and barley. The grain had been used for consumption of both humans and livestock and also different genes of the plant serve many other important uses. The crop has been suffer from various type of diseases, majority of them are known to be caused by fungi, which are mostly seed born. In present study Seed-borne fungi of sorghum in Marathwada region were surveyed. A total of 24 seed samples of eight different varieties from various locations, collected were tested, using the blotter and agar plate methods. Twenty eight fungal species of eighteen genera appeared in the seeds of eight different variety of Sorghum. In untreated seeds of the entire varieties maximum incidence was of Curvularia lunata. Treated seeds showed complete absence of Cladosporium herbarum, Trichothecium roseum and Absidia ramose. Agar plate method was found to be favorable for the maximum counts of saprophytic fungi and also favorable for detection of some specific fungi. Presence of many pathogenic fungi in considerable number of seed samples indicates the need of field surveys for these and other pathogens.Â

A study of maternal and perinatal outcome in patients of postpartum hemorrhage in a tertiary care hospital, Gujarat

Background: Postpartum hemorrhage (PPH) is significant factor for maternal mortality. Prevalence of PPH is 6.0% worldwide and highest prevalence was noted in Africa which is almost 10.1%. In India, maternal hemorrhage is the very common factor for maternal mortality. The objective of the study was to understand incidence of PPH and various risk factors for it, to study maternal morbidity and mortality associated with PPH and to study the effective mode of management in PPH.Methods: This prospective study was done among 50 cases of postpartum haemorrhage out of 13,628 deliveries at civil hospital, Asarwa, Ahmedabad during November 2008 to October 2010 and analysis was done regarding patients’ socio demographic characteristics, various risk factors, causes and maternal and perinatal outcome.Results: Incidence of PPH was 0.36%. Almost >85% cases were belonged to 20-34 years age group. Highest cases (38%) seen in primigravida and 72% cases have normal vaginal delivery. Anemia noted in highest cases (22%) and 68% cases have most common etiology was atonicity. Birth weight <2.5 kg found in 36% cases. Most common maternal outcome was fever (16%) and 72% cases delivered healthy and alive birth.Conclusions: The patients were mostly primiparous. The commonest associated medical condition was anemia. The commonest underlying cause of PPH was atonicity of the uterus. Commonest maternal outcome was fever. Out of total births, 72.0% were alive and healthy babies followed by 18.0% babies were still birth

The high-pressure behavior of CaMoO4

We report a high-pressure study of tetragonal scheelite-type CaMoO4 up to 29 GPa. In order to characterize its high-pressure behavior, we have combined Raman and optical-absorption measurements with density-functional theory calculations. We have found evidence of a pressure-induced phase transition near 15 GPa. Experiments and calculations agree in assigning the high-pressure phase to a monoclinic fergusonite-type structure. The reported results are consistent with previous powder x-ray-diffraction experiments, but are in contradiction with the conclusions obtained from earlier Raman measurements, which support the existence of more than one phase transition in the pressure range covered by our studies. The observed scheelite-fergusonite transition induces significant changes in the electronic band gap and phonon spectrum of CaMoO4. We have determined the pressure evolution of the band gap for the low- and high-pressure phases as well as the frequencies and pressure dependences of the Raman-active and infrared-active modes. In addition, based upon calculations of the phonon dispersion of the scheelite phase, carried out at a pressure higher than the transition pressure, we propose a possible mechanism for the reported phase transition. Furthermore, from the calculations we determined the pressure dependence of the unit-cell parameters and atomic positions of the different phases and their room-temperature equations of state. These results are compared with previous experiments showing a very good agreement. Finally, information on bond compressibility is reported and correlated with the macroscopic compressibility of CaMoO4. The reported results are of interest for the many technological applications of this oxide.Comment: 36 pages, 10 figures, 8 table

A seven-equation diffused interface method for resolved multiphase flows

The seven-equation model is a compressible multiphase formulation that allows for phasic velocity and pressure disequilibrium. These equations are solved using a diffused interface method that models resolved multiphase flows. Novel extensions are proposed for including the effects of surface tension, viscosity, multi-species, and reactions. The allowed non-equilibrium of pressure in the seven-equation model provides numerical stability in strong shocks and allows for arbitrary and independent equations of states. A discrete equations method (DEM) models the fluxes. We show that even though stiff pressure- and velocity-relaxation solvers have been used, they are not needed for the DEM because the non-conservative fluxes are accurately modeled. An interface compression scheme controls the numerical diffusion of the interface, and its effects on the solution are discussed. Test cases are used to validate the computational method and demonstrate its applicability. They include multiphase shock tubes, shock propagation through a material interface, a surface-tension-driven oscillating droplet, an accelerating droplet in a viscous medium, and shock-detonation interacting with a deforming droplet. Simulation results are compared against exact solutions and experiments when possible

Reduction of cogging torque of radial flux permanent magnet brushless DC motor by magnet shifting technique

  Introduction. In spite of many advantages of radial flux permanent magnet brushless DC motors it suffers from the distinct disadvantage of high cogging torque. The designer must emphasize to reduce the cogging torque during the design stage. This paper introduces magnet shifting technique to mitigate cogging torque of surface mounted radial flux brushless DC motor. Methodology. Initially 200 W, 1000 rpm surface mounted radial flux permanent magnet brushless DC motor is designed with symmetrical placement of permanent magnets with respect to each other on rotor core. Cogging torque profile of this initial motor is obtained by performing finite element modelling and analysis. Originality. This design has been improved by shifting the position of permanent magnets with respect to adjacent permanent magnets. The effect of magnet shifting on cogging torque has been analyzed by performing finite element analysis. Results. It has been examined that the peak to peak cogging torque is decreased from 1.1 N×m to 0.6 N×m with shifting of permanent magnets respectively.Вступ. Незважаючи на багато переваг безщіткових двигунів постійного струму з радіальним магнітним потоком, вони мають явний недолік, що полягає у високому крутному моменті зубчатої передачі. Проектувальник повинен зосередитись на зниженні крутного моменту зубчатої передачі на етапі проектування. У цій статті представлена методика зсуву магніту для зменшення крутного моменту зубчатої передачі безщіткового двигуна постійного струму з радіальним потоком, встановленого на поверхні. Методологія. Спочатку безщітковий двигун постійного струму з радіальним магнітним потоком потужністю 200 Вт, 1000 об/хв спроектований із симетричним розміщенням постійних магнітів відносно один одного на сердечнику ротора. Розподіл крутного моменту зубчатої передачі цього початкового двигуна отриманий шляхом аналізу методом скінчених елементів (МСЕ). Оригінальність. Ця конструкція була вдосконалена за рахунок зсуву положення постійних магнітів по відношенню до сусідніх постійних магнітів. Вплив зсуву магніту на крутний момент зубчатої передачі було проаналізовано за допомогою аналізу МСЕ. Результати. Досліджено, що піковий крутний  момент зубчатої передачі зменшився з 1,1 Н×м до 0,6 Н×м, відповідно, при зсуві постійних магнітів
