The Stress Parameter

This study was conducted to evaluate the salt tolerance ability of two soybean cultivars under salinity conditions using a selection of growth and physiological parameters. In this study, we identified that the D140 soybean cultivar had a better salt tolerance than the D8 soybean cultivar at a 100 mM NaCl concentration.

The modulus reduction and damping curves represent the nonlinear behavior of soil under cyclic load. In the literature, those curves were produced from lab tests of soil at particular confining stresses. This study developed a set of parameters that can be used to normalize the modulus reduction and damping curves to be stress-independent.

The main parameters of this device are calculated from the ratio of shear stress and normal stress at the fatigue of the asphalt concrete according to the Mohr-Coulomb failure criterion. Test results with asphalt specimens show that the device is stable, the acting vertical loads were smaller and more stable.

This study uses chitin as a filler for a polyurethane composite foam. The obtained polymer composite materials (PCM) are examined the technological parameters of the foaming (start time, rise time, and apparent density), the physical-mechanical properties (the compressive stress, compression set, resilience), and the cross-link density.

The numerical wedge splitting tests show that in the case of brittle materials, the lower post-failure stress limit defined in the concrete damaged plasticity model resulted in energy consumption for crack propagation exceeding the defined fracture energy (114% higher in the case of a brittleness number of 4.4).

Cardiac hypertrophy (CH), leading to cardiac failure is due to chronic metabolic alterations occurring during cellular stress. Besides the already known relationship between oxidative stress and CH, there are implications of reductive stress leading to CH. This study attempted to develop reductive stress-based CH rat model using n-acetyl-L-cysteine (NAC), a glutathione agonist that was compared with typical isoproterenol (ISO) induced CH model.

A Total 8 semen sample from four healthy Gir breeding bulls were collected at weekly interval for two weeks period using of artificial vagina method for evaluation of semen biochemical attributes at various stages of cryopreservation of Gir bull semen. The overall mean values for oxidative stress parameters viz. lipid peroxidation and glutathione reductase were 51.14 ± 0.18 μmol/ml and 32.24 ± 0.64 U/L, respectively in neat semen samples.

Three separate experiments were carried out to assess combined effects of temperature and salinity and induced stress on blood variables of Tra catfish (Pangasianodon hypophthalmus) fingerlings. Some hematological parameters included Haemoglobin concentration, glucose and pH levels which were tested in different conditions. The experiment 1 aimed to test how blood variables change in different temperature (24, 28-30, 32 oC) and salinity (0, 6 and 12 ppt) while the experiment 2 induced catfish fingerlings to different stress time (5, 15 and 30 min.).

About a decade ago, the elastic properties of a single chromatin fiber and, subsequently, those of a single nucleosome started to be explored using optical and magnetic tweezers. These techniques have allowed direct mea-surements of several essential physical parameters of individual nucleo-somes and nucleosomal arrays, including the forces responsible for the maintenance of the structure of both the chromatin fiber and the individual nucleosomes
