in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.

Two methods were proposed for determining alpha-particle fluence for radiobiological experiments. The first involved calculating the probabilities of hitting the target for alpha particles emitted from a source through Monte Carlo simulations, which when multiplied by the activity of the source gave the fluence at the target. The second relied on the number of chemically etched alpha-particle t...

To measure radiation damage of particles with high energy and charge in space, radiosensitive plastics are used, in which particles leave damage tracks where they pass. These tracks are then etched, after which they have a typical cone shape. The geometrical parameters of these cones give information about energy and charge of the particles. To measure these parameters, the tracks are recorded ...

Background: In this study, measurement of indoor radon and its progeny levels was carried out in Gas Turbine Power Station in Haryana ( India ), where natural gas is used as fuel. For comparison, the results of a study carried out in thermal power plant in Haryana are also presented. Radon being a ubiquitous air pollutant has global impact and its monitoring in the environment at work places is...

The main design criteria of ballasted railway tracks include rail deflections, rail bending stresses, rail wheel contact stresses, sleeper bending moments and ballast sleeper contact pressures. Numerous criteria have been defined for the design of ballasted railway tracks owing to the various mechanical properties of track components and their complex interaction. Therefore, railway track desig...

The Madagascar seasat dataset presents a problem where data are collected along crossing tracks. These tracks are not straight, and appear to be irregular in the model space. Previous methods assumed that the data were regularly sampled in the model space coordinate system. I warp the model space to look more like the data space, so that prediction-error filters can be estimated in the more reg...

RNA processing, directed transport along cytoskeletal tracks, and site-specific translation of mRNA at the cell periphery are considered discrete steps in the generation of microfilament-membrane adhesion complexes. A recently identified member of the heterogeneous nuclear ribonucleoprotein family, raver1, may couple these steps and contribute to the assembly and maintenance of these structures.

Micrographs of energetic particles in nuclear emulsion are simulated by computing the spatial distribution of developed grains with the δ-ray theory of track structure, and representing the developed grains by points of light on an IBM 2250 visual display unit. The simulated tracks display many of the features of actual track structure and serve as a visual comparison between experiment and the...
