to compare the efficacy of acupressure wrist bands, ondansetron, metoclopramide and placebo in the prevention of vomiting and nausea after strabismus surgery. two hundred patients, asa physical status i or ii, aged between 10 and 60 years, undergoing strabismus surgery in farabi hospital in 2007-2008 years, were included in this randomized, prospective, double-blind and placebo-controlled study...
Ecotones are zones of gradual changes from an ecological system to another.Ecotones monitoring could be important to find out the reason for changes and limits. Inthis research satellite data were used to analyze the ecotone boundary in Fars steppicrangelands using IRS LISS III and Pan data of year 2006. The real vegetation map andecotones prepared through Geo-eye images from Google earth softw...
Current study monitored Electerical Conductivity (EC) as soil salinity index and Organic Matter (OM) in the area of Harat in Yazd, Iran, through remote sensing technology with high spatial and spectral resolution. The images were selected from IRS, LISS III satellites between the years 2008 and 2012. After preprocessing and analyzing the images, the relationship between parameters of (EC) an...
برآوردهای کمّی و دقیق از مشخصات توده های جنگلی، تضمینی بر مدیریت صحیح آن ها است. تصاویر سنجش از دور با توجه به اطلاعات مکانی دقیق و وسیع، همواره ابزاری مقرون به صرفه در مدیریت جنگل بوده و یکی از عمومی ترین کاربردهای تصاویر ماهواره ای در علم جنگلداری، طبقه بندی مشخصه های توده های جنگلی و تهیه نقشه های موضوعی آن ها است. در سال های اخیر روش های مختلف ترکیب داده های تصاویر سنجش از دور و داده های حاص...
Monitoring the salt crusts in arid areas by satellite data processing in this research, monitoring the salt crusts of KASHAN and MAHARLOO arid areas by using LISSIII datas of IRS-P6 satellite was accomplished. After exerting essential corrections for visual inter pretation , contrast optimization and making pseudo-colorful images were used to specity the salt crusts. Then , according to the sal...
The objectives of this project are to create a spatial digital database consisting of LU/LC and road network maps with the help of IRS-ID, PAN & LISS-III merged data and SOI toposheets, to create database consisting of traffic volume, vehicle density and details of solid waste and to evolve an optimal transportation route maps for efficient, safe and economic disposal of solid waste. The final ...
با گسترش شهرها و رشد جمعیت همراه با افزایش آلودگی محیط زیست بر اثر فعالیتهای انسانی، تغیرات غیراصولی در پوشش گیاهی و فضای سبز ایجاد شده است. در توسعۀ پایدار اراضی، مدیریت تغییر کاربری اراضی عامل مهمی به شمار میآید. سنجش از دور میتواند منبع مناسبی برای تهیۀ دادهها بهمنظور تهیۀ نقشۀ انواع پوشش اراضی همچنین پایش محیط زیست باشد. در این پژوهش که هدف بررسی روند تغییرات فضای سبز کلانشهر کرج است...
The IRS-1D LISS III false colour composite (FCC) decoded imagery belonging to Kosi river watershed of Almora district of Uttaranchal under warm humid Lesser Himalayan agro-ecological region was interpreted and surveyed for soil resource mapping. On the basis of image interpretation and ground truth study ten physiographic units were identified. Soil physiography relationship was established on ...
Canopy reflectance model inversions are widely used for estimation of vegetation properties from remote sensing, but the inversion accuracy needs significant improvements. In recent years, applications of the genetic algorithms (GA) to a variety of optimization problems in remote sensing have been successfully demonstrated. The present study is focused on the GA based inversion approach of radi...
