Abstract

An improved higher-order zigzag plate theory in a random environment is proposed and it is implemented in a stochastic finite element framework to study the buckling characteristic of sandwich plates with random material properties. The theory satisfies transverse shear stress continuity at all of the layer interfaces and the transverse shear-stress-free condition at the top and bottom surfaces. It also includes the effect of transverse deformability to the core. The through-thickness variation of in-plane displacements is assumed to be cubic, whereas transverse displacement varies quadratically within the core and it remains constant over the face sheets. Note that sandwich and composite structures are characterized by inherent uncertainties in their material properties. The effect of these uncertainties on the buckling characteristic of sandwich plates is studied by modeling the macromechanical material properties as basic random variables. A stochastic finite element method consisting of an efficient [C.sup.[theta]] finite element in conjunction with a mean-centered first-order perturbation approach is developed, and the model is employed to evaluate the second-order statistics of the buckling loads. The published results are used to validate the deterministic part of the proposed approach, and its stochastic component is validated with an independent Monte Carlo simulation.

39. Mutagenic effectiveness and efficiency of gamma rays in snake gourd (Trichosanthes anguina l.)

Author

Sidhya, P., Pandit, M.K., Sidhya, P., and Pandit, M.K.

Abstract

The present experiment was undertaken to determine the mutagenic effectiveness and efficiency of gamma rays on different biological parameters in snake gourd. The research was conducted in two generations namely M1 and M2 during spring-summer season (mid- February) of 2012 and 2013 at the Horticulture research station, Mondoury, Bidhan Chandra Krishi Viswavidyalaya. The parent material, selfed seeds of BCSG-28 variety were irradiated with 100 Gy, 150 Gy, 200 Gy, 250 Gy and 300 Gy doses of gamma rays. The seeds along with control were space planted for raising M1 generation. Each M1 plant was harvested separately and desirable M1 individual plant progeny rows were laid in RBD for raising M2 generation. The effectiveness and efficiency of the mutagen used was assessed from the data on biological damage in M1 generation. In M1 generation, results showed a dose dependent retardation in biological parameters like seed germination, plant survival and 200 Gy was depicted as LD50 indicating less damaging effect at lower doses on genetic material. In M2 generation, Lower doses 100 Gy (28.80 effectiveness, 21.58 efficiency) and 150 Gy (18.33 effectiveness, 8.68 efficiency) treatments were found as effective and efficient and a wide range of induced variability was observed in almost all traits. The mutants with short fruit, higher fruit diameter and reduced vine length were isolated in M2 generation.

Abstract

We conducted field studies in the Jiwa valley (Indian Himalayas) to examine the influence of human disturbance on Himalayan pheasants. We used the “call count” and “line transect” methods to estimate the abundance of pheasants in Jiwa valley. A human disturbance gradient defined by human population, agriculture activity, forest wood collection, grazing, vehicle, use of heavy machines, human settlements, dumping ground, and blasting was prepared. Проведены полевые исследования в долине Джива (Индийские Гималаи) для оценки влияния фактора беспокойства на гималайских фазанов. Для оценки численности фазанов в долине Джива использовали метод учета по голосам и трансектный метод. Градиент фактора беспокойства определен по оценке количества населения, сельскохозяйственной деятельности, вырубке лесов, выпасу, транспорту, использованию тяжелых машин, человеческим поселениям, использованию земли под свалки и направленным взрывам.
