this study is designed, aiming to detect changes in the composition and configuration of landscape in rasht township between 1989 and 2011. it has been conducted applying synoptic analysis. hence, landscape maps have been generated from three tm satellite images at 1987, 1999 and 2011 applying hybrid classification method. some composition and configuration-based metrics including np, pd, lsi, ...

AIMS Radiological inappropriateness in medical imaging leads to loss of resources and accumulation of avoidable population cancer risk. Aim of the study was to audit the appropriateness rate of different cardiac radiological examinations. METHODS AND PRINCIPAL FINDINGS With a retrospective, observational study we reviewed clinical records of 818 consecutive patients (67 ± 12 years, 75% males)...

BACKGROUND Duplex ultrasonography criteria for assessing the severity of carotid artery (CA) in-stent restenosis are not well established. METHODS AND RESULTS We analyzed 39 patients (40 CAs) who underwent CA stenting with baseline and 6-month follow-up carotid duplex ultrasonography and intravascular ultrasound. Intravascular ultrasound measurements included minimum luminal diameter, percent...

distinguishing the susceptible areas to landslide using different landslide susceptibility mapping (lsm) models is one of the primitive and basic works to reduce probable damages and reduce risk. the main purpose of this research is the efficiency evaluation of four methods including information value (winf), valuing area accumulation (wa), analytical hierarchy process (ahp), kopta-joshi propos...

Background & Aim: The present study was to identify the medicinal plant species and introduced as one of the key priority areas for conservation and determination of endangered species were done. Experimental: The method of plant collection in this region was classical method of regional plant taxonomic studies. Collected plants were recognized and determined families, genera and species of th...

Desertification process as a great problem affects most of the countries in the world specially developing countries. This process has a high rate in arid and semi-arid countries such as Iran. The main objective of this research was to investigate land degradation status and desertification mapping of Kashan area. Different studies have been carried out in the world in order to assess desertifi...

Selective laser sintering (SLS) is one of the most popular 3D molding technologies; however, manufacturing steps SLS machines are cumbersome, and important step focused on testing because it requires a lot direct labor material costs. This research establishes advanced hybrid mathematical classification models, including random forest (RF), support vector machine (SVM), artificial neural networ...

Heterodimeric class I phosphoinositide 3-kinase (PI3K) has been shown to be involved in the stimulation of voltage-gated Ca channels by various mediators. In this study, we bring evidences that vascular L-type Ca channels can be modulated by both tyrosine kinase–regulated class Ia and G protein–regulated class Ib PI3Ks. Purified recombinant PI3Ks increased the peak Ca channel current density wh...

Heterodimeric class I phosphoinositide 3-kinase (PI3K) has been shown to be involved in the stimulation of voltage-gated Ca(2+) channels by various mediators. In this study, we bring evidences that vascular L-type Ca(2+) channels can be modulated by both tyrosine kinase-regulated class Ia and G protein-regulated class Ib PI3Ks. Purified recombinant PI3Ks increased the peak Ca(2+) channel curren...
