today the image of a permanent skeletal space of cities affected by some forces or mechanisms is put in time with social-economic development and while imposes a new face and perspective to physical anatomy of cities, and prepares field to changes in content and social- economic structures of cities too. simultaneously with quitting villages in order to settle in cities by villagers, the phen...
a novel and ultra low cost isfet electrode and measurement system was designed for isfet application and detection of hydronium, hydrazinium and potassium ions. also, a measuring setup containing appropriate circuits, suitable analyzer (advantech board), de noise reduction elements, cooling system and pc was used for controlling the isfet electrode and various characteristic measurements. the t...
THE most recent work on the decomposition of lecithin is due to Fischgold and Chain [1934], who have obtained evidence that lecithin, even in the absence of air, undergoes a spontaneous change. This change was found to be due to separation of free fatty acid from the lecithin molecule. C. W. Price and Lewis [1933, 1] noted a change in the electrophoretic properties of lecithin as it became aged...
in this thesis, a structured hierarchical methodology based on petri nets is used to introduce a task model for a soccer goalkeeper robot. in real or robot soccer, goalkeeper is an important element which has a key role and challenging features in the game. goalkeeper aims at defending goal from scoring goals by opponent team, actually to prevent the goal from the opponent player’s attacks. thi...
the subjects of the study are only the tefl teachers and students at gilan university. to obtain the desired data, a questionnaire which was based on the theories and disecussions gathered, was used as the main data gathering instrument. to determine the degree of relationship between variables, covariance and pearson product moment correlation coefficient were the formulas applied. the data we...
In a 42-d experiment, 576 one-day-old Vencobb 308 broiler chicks were used to investigate the effects of lecithin extract (0.5 g/kg), choline chloride 60% (1 g/kg) and Bio choline (1 g/kg) in diets of moderate and high energy in a 4 × 2 factorial arrangement on performance and certain physiological traits in broiler chickens. The inclusion of Bio choline and lecithin extract in the diet signifi...
Background: Frozen-thawed rooster semen is not reliable for use in artificial insemination in commercial stocks. Low density lipoprotein (LDL) has been assessed for effectiveness as a cryoprotectant in the extender to improve the quality of frozen-thawed rooster semen. Although LDL has been evaluated in a few studies in other species for semen cryopreservation, to date, no study has been conduc...
Extender based forcings are studied with respect of adding branches to Aronszajn trees. We construct a model with no Aronszajn tree over אω+2 from the optimal assumptions. This answers a question of Friedman and Halilović [1]. The reader interested only in Friedman and Halilović question may skip the first section and go directly to the second. 1 No branches to κAronszajn trees. We deal here wi...
among the low–dimensional allotropes of carbon, nanotubes and graphene have attracted very much attention from nano–science and nanotechnology specialists. they have been proposed as building blocks in nanometer device engineering. however, these structures are not defect–free. in this thesis, we focused on defective carbon nanotubes and graphene, and studied the effect of couple of very common...
Pterostilbene, a dimethylether analog of resveratrol, has been found to have potent biological activity. However, the bioavailability pterostilbene in system is limited due its poor solubility an aqueous environment. A nanoemulsion was designed for this purpose. Lecithin-based formed after 3 cycles through high-pressure homogenizer at 500 psi. The rheological properties and particle size were m...
