The forest landscape pattern evolution can reveal the intensity and mode of action human–land relationships at different times in spaces, providing scientific support for regional ecological security, human settlement health, sustainable development. In this study, we proposed a novel method analyzing dynamics patterns. First, patch density (PD), largest index (LPI), shape (LSI), contiguity (CI...
Development of roads through protected areas and ecological sensitive regions can have catastrophic effects on wildlife. In Iran, road construction in sensitive habitats and protected areas has been expanding during the past decades. This study focuses on the ecological impacts of Isfahan’s west ringway, which passes through Ghamishloo wildlife refuge, I.U.C.N category IV, in Isfahan Province. ...
objective: the objective of this study was to investigate the invitro fluoride release of four new self-adhesive resin cements; set (sdi, australia), breeze (pentron, usa), embrace wetbond (pulpdent, usa), g-cem (gc, japan) and to assess the bonding performance of these self-adhesive resin cements for bonding of orthodontic brackets. materials and methods: for fluoride release experiment, six ...
the methods which are used to analyze microstrip antennas, are divited into three categories: empirical methods, semi-empirical methods and full-wave analysis. empirical and semi-empirical methods are generally based on some fundamental simplifying assumptions about quality of surface current distribution and substrate thickness. thses simplificatioms cause low accuracy in field evaluation. ful...
Background: Tetralogy of Fallot is the most common cyanotic congenital heart disease. The systolic and diastolic function in both ventricles is altered even after successful corrective surgery for this defect with a transannular patch. Pulmonary regurgitation, a common complication after this treatment, is usually well tolerated in childhood. The aim of this study was to assess the combined dia...
BACKGROUND AND PURPOSE Highly vascularized ovarian carcinoma secretes the putative endocannabinoid and GPR55 agonist, L-α-lysophosphatidylinositol (LPI), into the circulation. We aimed to assess the involvement of this agonist and its receptor in ovarian cancer angiogenesis. EXPERIMENTAL APPROACH Secretion of LPI by three ovarian cancer cell lines (OVCAR-3, OVCAR-5 and COV-362) was tested by ...
Country-wise Logistics Performance Index (LPI) is insufficient to guide changing policies for different sectors with varied logistics requirements and perspectives. Each perspective has various measures, hence a battery of scales mandated measure the performance an individual sector like marine, agriculture, similar. For marine-product India, scores are transformed combined follow normal distri...
gol-e-gohar iron ore mine of sirjan in southern part of iran is a large open pit that operates below the groundwater table and during mining operation, dewatering is required to prevent operation processes from flooding. current operation is going on by digging wells in or out of the pit and pumping to prevent flooding. as a result of the former dewatering operation a vast deep cone of depressi...
