this research was conducted to investigate spatial variability and estimate tree attributes in a plantation forest in the caspian region of iran using geostatistical analysis. sampling was performed based on a 50m?125m systematic grid in a maple stand (acer velutinum boiss) 18 years of age using circular samples of 200m2 area. totally, 96 sample plots were measured in 63 hectares and 14.25 hect...

erosion is one of the important social-economic problems in iraniancatchments that have been posed by surface water vastness and runoff production. so, thestudy of water resources, soil erosion and effective factors is of high importance. gullyerosion also extends in many parts of iran and its study particularly in viewpoint ofsediment yield is therefore very important and should be taken into ...

the asia-pacific region generates over half of global economic activity (54.2%) and about 43.7% of global trade, and is the most dynamic region in the global economy. at the core of this is an increasingly dynamic, vibrant and entrepreneurial small-medium sized enterprise sector. advances in information and communications technology, market liberalisation and moves towards closer regional econo...

the objectives of the present study were to investigate the prevalence of histologic thyroids lesions and the respective thyroid hormones changes of ewes in an endemic goiter region and to find out any impact of this condition on the fetal thyroid structures and serum thyroid hormones. in the present study a total number of 100 pregnant ewes and their fetuses slaughtered at slaughterhouse were ...

objective: hepatitis c virus is the major cause of viral hepatitis and its diagnosis in suspected specimens is of great importance. the risk of transfusion- transmitted virus infection is primarily the result of failure in serological screening tests to detect recently infected donors in the pre-seroconversion window period of infection. therefore, sensitive and accurate diagnosis of hcv prior ...

this study provides new data on chromosomal characteristics and dna barcoding of three endemic loaches of iran: spiny southern loach cobitis linea (heckel, 1847), persian stream loach oxynoemacheilus persa (heckel, 1848) and tongiorgi stream loach oxynoemacheilus tongiorgii (nalbant & bianco, 1998). the chromosomes of these fishes were investigated by examining metaphase chromosome spreads ...

the growth hormone receptor (ghr) is a member of cytokine/hematopoietin family that mediates the biological actions of growth hormone (gh) on target tissues. therefore, the purpose of this study was to examine the association of tg-repeat polymorphisms in the 5’-flanking region of bovine ghr gene with milk production traits and somatic cell score (scs) in holstein cattle of iran. the part of 5’...

cauda equina syndrome (ces) although uncommon, is a very serious condition, which should be diagnosed as soon as possible.  urinary dysfunction following a lumbosacral trauma is a key for the physician to consider ces as the most probable diagnosis. up to 62% of ces patients report a recent episode of trauma. we herein report a young man with ces due to sacral fracture with an interesting imaging.
