Background: Following the expansion of human infertility, different procedures have been utilized for separation of normal sperm during ICSI (Intra cytoplasmic sperm injection). Hypo-osmotic swelling test (HOST) is one of the tests which have been introduced for assessment of integrity of sperm membrane when confronted with hypo osmotic condition. This test may also reflect intracellular organe...
applications such as high definition viedeo reproduction, portable computers, wireless, and multimedia demand, and ever-increasing need for ligh-frequency high-resolution and low-power analog-to-digital converters. flash, two-step flash, and pipeline convertors are fast but consume large amount of power and require large area. to overcome these problems, successive approximation converter blo...
many mobile and off-grid devices include electronics and other electrical consumers like servo drives, which need a quite low supply power. since the price for photovoltaic modules drops continuously, photovoltaic power supply is interesting in more and more applications. in solar powered systems, a battery is needed to store energy for the night and cloudy periods. the power electronics of suc...
Dianthus barbatus is an important ornamental bedding plant in temperate regions with traditional medicinal applications. Water shortage and drought stress are major limitations for landscape development and plant medicine production. Callogenesis is the key step for modern plant breeding techniques and in vitro drought stress study defines the mechanisms of plant response to stress. Therefore t...
Macromol. Biosci. 2002, 2, 207 –213 Full Paper: Calcium ions are introduced to sodium polyacrylate gels swollen in sodium chloride solutions and the volume transition is measured by osmotic and small-angle neutron-scattering. The osmotic pressure is found to depend on the sodium chloride con centration, indicating that calcium preferen tially replaces condensed sodium ions, a result supported...
This research was performed in 2011 at University of Mohaghegh Ardabili, Iran, to evaluate osmotic-stress tolerance, at seedling stage, of rapeseed (Brassica napus L.), as a split plot experiment based on randomized complete blocks design with four replications. Levels of osmotic stress were considered as main factor and twelve rapeseed cultivars were sub-factor, that were evaluated under aquac...
Analysis of the osmotic pressures of aqueous poly(ethylene glycol) solutions indicates a power-law behavior in the range of volume fractions from 0.08–0.12 to 0.33 or higher, for polymers with average molecular masses in the range 1500– 4000 Da. The exponent of the power law is closer to a value of 2, which is predicted by mean-field theory, than to the value of 5/4, which is predicted by scali...
A practical method of analysis of osmotic-and-diffusive conversion of free energy of solutions with different concentrations in membrane systems, which was elaborated previously (Kargol 1990) is experimentally verified in this work. A proper membrane system was chosen for examination. Equations for power and efficiency were obtained in a mathematically simple way for this system as an example o...
Artilysins represent a novel, promising class of antibacterials, exploiting the lytic power of bacteriophageencoded endolysins. These enzymes are produced by bacteriophages at the end of their lytic replication cycle. Once the endolysins have passed through the cytoplasmic membrane, they degrade the peptidoglycan layer rapidly, causing osmotic lysis of the infected cell and liberation of the pr...
