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...
Radiation damage is to a large extent caused by overproduction of reactive oxygen species (ROS). Radioprotectors are agents or substances that reduce the effects of radiation in healthy normal tissues while maintaining the sensitivity to radiation damage in tumor cells.Radioprotectors are agents or substances that reduce the effects of radiation in healthy normal tissues while maintaining the s...
this study investigated the effects of planning on second-language written production with regard to task type. the participants were 75 iranian learners of english as a foreign language attending a private foreign language institution. they were asked to complete two different types of writing tasks (expository writing task and argumentative writing task) in different planned conditions (indiv...
A heuristic way to calculate the approximate value of the Casimir force is introduced
both heliophysical and anthropogenic (wastewater) effects on zooplankton biomass and abundance of the imandra lake (the largest subarctic lake at kola peninsula, russia) were investigated during the 1990 - 2003 period. we used different indexes of solar activity (sunspot numbers and uv- radiation values) as heliophysical factors. information about uv- radiation values was derived from satellite...
background : we intend to study the inhibitory effect of sulfur compound in ramsar hot spring mineral on tumor-genesis ability of high natural background radiation. objective : the radioprotective effect of sulfur compounds was previously shown on radiation-induced chromosomal aberration, micronuclei in mouse bone marrow cells and human peripheral lymphocyte. ramsar is known for having the high...
