Water permeability coefficients of dog, cat, and beef red cell membranes have been measured under an osmotic pressure gradient. The measurements employed a rapid reaction stop flow apparatus with which cell shrinking was measured under a relative osmotic pressure gradient of 1.25 to 1.64 times the isosmolar concentration. For the dog red cell the osmotic permeability coefficient is 0.36 cm(4)/(...
plant growth is often limited by low levels of soil micronutrients such as copper (cu), especially in calcareous salt-affected soils of arid and semiarid regions. the aim of this work was to investigate individual and combined effects of salinity and cu on growth, leaf relative water content (lrwc), cell membrane permeability, lipid peroxidation, and total phenolic content (tpc) of rosemary...
in this thesis a calibration transfer method is used to achieve bilinearity for augmented first order kinetic data. first, the proposed method is investigated using simulated data and next the concept is applied to experimental data. the experimental data consists of spectroscopic monitoring of the first order degradation reaction of carbaryl. this component is used for control of pests in frui...
abstract: since sugar consumption is directly related to diabetes and other illnesses such as obesity, the issue that will most heavily dominate the health food market is blood sugar management and low glycemic foods. using calcium chloride and gums such as sodium alginate and low ester pectin as thikener and a high-potency sweetener aspartame we were able to reduce sugar content of sour cherry...
Underground Hydrogen Storage (UHS) is an emerging large-scale energy storage technology. Researchers are investigating its feasibility and performance, including injectivity, productivity, capacity through numerical simulations. However, several ad-hoc relative permeability capillary pressure functions have been used in the literature, with no direct link to underlying physics of hydrogen produ...
The eggs of Teleogrylhis commodus, like those of many other species of insects, absorb water during their development. The water enters through the shell at a specific stage in the egg's development, and there is an as yet unresolved problem as to how the control of the flow of water is effected (Browning, 1967). Recently it has been shown that the isolated egg-shell of Locusta migratoria migra...
in this research, the bioinsising impact of two wood decay fungi (pysisporinus vitreus and xylaria longipes) on radial air permeability and moisture diffusion coefficient of spruce wood (picea abies) was investigated. fungal cultivation was performed in an incubator at 25 °c and 85% relative humidity for 15, 30 and 45 days. results showed that the permeability, moisture diffusion and mass loss ...
within communicative, interactive, and learner-centered framework of language teaching and learning, students need to learn four skills of listening, speaking, reading, and writing for their educational success. but of all the language skills, reading enjoys a paramount significance in so many second or foreign language academic contexts. in spite of its importance, language learners still have...
The effect of dry material, glycerol and ratio of water to seed in alyssum homalocarpum films on their thickness, transparency, moisture content, tensile strength, elongation and water vapor permeability was investigated using mixture response surface methods. Dry material and glycerol were important factors influencing tensile strength, elongation and water vapor permeability. Ratio of water t...
1. Electrical potential differences (p.d.'s) have been measured across an in vitro preparation of rabbit gall-bladder.2. When the gall-bladder separates identical bathing solutions, the p.d. is always zero, regardless of the composition of the bathing solution. Hence the gall-bladder is symmetrical: i.e. the mucosal and serosal cell membranes have the same relative permeability coefficients.3. ...
