in order to evaluate the possible correlation between the tree density and the human population density, the forested area in nav asalem district located in guilan province was selected. the descriptors of tree number and basal area per hectare as well as the stand density index were used to determine the tree density, which was conducted from a 2014 forest inventory including 62 cluster (558 p...

prioritization of sub-watersheds is very important in the natural sources and watershed management. in this study, the morphometric parameter and landuse changes using rs and gis techniques used in order to identify erosion-prone sub-watersheds. the morphometric parameter such as basin relief, the linear parameters (drainage density, bifurcation ratio, length of overland flow, stream frequency ...

BACKGROUND We previously reported the utility of preoperative nuclear morphometry for evaluating risk for cervical lymph node metastases in tongue squamous cell carcinoma. The risk for lymph node metastasis in oral squamous cell carcinoma, however, is known to differ depending on the anatomical site of the primary tumor, such as the tongue, gingiva, mouth floor, and buccal mucosa. In this study...

during early neurogenesis, the floor plate plays an essential role(s) in the differentiation of the ventral portion of neural tube. in this study, we detected the specific distribution of unique glycoconjugate during the floor plate differentiation. formalin fixed paraffin sections of balb/c mice (10-14 embryonic days) were processed for histochemical studies using horseradish peroxidase-labell...

the occurrence of epidermoid and dermoid cysts in the oral cavity is extremely rare accounting 0.01% of all cysts. in our case report we hereby present a large epidermoid cyst in the floor of mouth imitating a plunging ranula. a 26-year-old female reported to us with a complaint of a swelling below the tongue since 2 year. on examination there was a swelling in the left side of the floor of the...

Background: Radon concentration was measured in the soil and indoor of Amman and Al- Rusaifa cities in Jordan during summer season. Materials and Methods: The measurement was performed using time-integrated passive radon dosimeters, containing a solid state nuclear track plastic detector, commercially known as CR-39. Results: Radon concentration levels in the soil ranged from 2.8 ± 1...

At 30 minutes after intravenous administration of the glomerular renal agent TC-99m-DTPA, both right and left lateral views were obtained. We analyzed the ratio of optical densities (behind the ureter/In front of the ureter). In patients without gross renal failure or retroperitoneal disease, the ratio was always less than 1 (range 0.38 to 0.95, mean 0.68). This represents greater perfusi...
