صخلملا A total of 48 fresh water fishes, belonging to four species of the family Cyprinidae (Capoeta trutta, Chalcalburnus mossulensis, Cyprinion macrostomum and Leuciscus lepidus) were collected from Darbandikhan lake, southwest Sulaimaniya city, Kurdistan region, in the north of Iraq, from March to the end of July 2008. The inspection of gills revealed the infection of these fishes with four ...

Earthquake prediction has two potentially compatible but distinctly different objectives: (a) phenomena that provide information about the future earthquake hazard useful to those who live in earthquake-prone regions and (b) phenomena causally related to the physical processes governing failure on a fault that will improve our understanding of those processes. For seismic hazard analysis in Vra...
Irrigation has a significant impact on regional water resources in south-eastern Australia. It is therefore important that objective assessments of the current use of water are undertaken on a routine basis. New remote sensing technologies now provide an opportunity to assess and monitor water use at farm and regional scales. This study demonstrates the use of satellite-based estimates of evapo...
This note concerns the updating of the land cover map of the Arno River basin (9.000 km) developed in the frame of a research project aimed at landslide risk assessment. The land cover map has been produced through the analysis of panchromatic/multispectral Landsat ETM+ images and TERRA-ASTER data; those data were integrated and compared with B/W and color ortho-photos. To improve photointerpre...
The goal of this project was to improve the mapping and monitoring system of the Directorate of Forest and Parks of the Province of Chubut, Patagonia. In providing updated quantitative and qualitative knowledge of Patagonian vegetation, mainly native forests, sustainable forest resource management shall be improved. In this paper object-oriented classification using eCognition software is prese...
Urban development has expanded rapidly in the Las Vegas, Nevada metropolitan area over the last fifty years. Associated with this growth trend has been the transformation of the landscape from natural cover types to increasingly impervious urban land. To map urban extent and its change over time, an innovative approach is employed that determines sub-pixel impervious surfaces from highresolutio...
گسیلمندی سطح زمین از جمله متغیرهایی است که در دامنه وسیعی از مطالعات و تحقیقات علوم زمین و محیط زیست کاربرد دارد و یکی از پارامترهای اساسی در برآورد دمای سطح می باشد. فناوری سنجش از دور، امکان پایش این کمیت را در سطح وسیعی فراهم می آورد. تغییرات گسیلمندی وابسته به پارامترهای سطح (نظیر بافت، توپوگرافی، رطوبت) و سنجنده ( نظیر قدرت تفکیک مکانی، تابع پاسخ طیفی ، و طول موج موثر باندها ) می باشد. در ...
Thessaly is a low relief region in Greece where hundreds of Neolithic settlements/tells called magoules were established from the Early Neolithic period until the Bronze Age (6,000 - 3,000 BC). Multi-sensor remote sensing was applied to the study area in order to evaluate its potential to detect Neolithic settlements. Hundreds of sites were geo-referenced through systematic GPS surveying throug...
