remote sensing is a key technology for assessing expansion and rate of land cover changes that awareness of these changes as the basic information has a special importance for various programs. in this study, land use changes were examined over the past 24 years, and the feasibility of predicting it in the future was evaluated by using the markov chain model of the abbas plain. landsat tm, etm+...

background: as we all know, sperm has the capacity to take up foreign dna, therefore, sperm mediated gen transfer can be an inexpensive and simple method in animal transgenesis in various species. however, there is not sufficient evidence of dna uptake by ovine spermatozoa. objectives: the purpose of the present study was to examine the uptake of human lysozyme gene contained plasmid (pegfp-ire...

climate change impacts on precipitation and temperature world-wide are not yet well understood (especially for precipitation), due to their complexity and regional variability. in this study in order to explicit the impact of climate change on precipitation and temperature in iran, 15 aogcm whose greenhouse gases scenarios ran under a2, a1b and b1 were used. monthly precipitation and temperatur...

in order to evaluate effect of azotobacter chroococcum strains on yield, yield components and qualitative indices of winter rapeseed (brassica napus l.), an experiment was conducted during 2009-2010 growing season at research institute of rice in rasht. the experimental design was completely randomized block, with three replications. investigated treatments were including control (without seed ...

forest roads are directions in natural habitats that used to transport wood products, secondary forest products and recreation. constructing forest roads causes trees clearing with specified width thus lead to direct or indirect changes in forest ecosystems and forest environment. this study aims to assess the changes of diversity and richness indices in main and secondary forest roads in a par...

inhalant anaesthetics are used widely for producing general anaesthesia in animals and humans.. approximately 20% of halothane uptake is metabolised via oxidative and reductive pathways during and following halothane anaesthesia in humans. fifteen clinically healthy dogs were assigned in three groups (group 1, 2and 3) randomly. all dogs were anesthetized with halothane three times that was repe...

determination of an optimum sample size for the evaluation of sugar beet quality is of vital importance. a desirable sugar beet sample could represent confidently the sugar content and quality of delivered beets to the sugar factories. this experiment was carried out at research station of kamalshahr, karadj, iran. the experimental field was about 2000 m2 with the distance between rows and plan...
