به منظور بررسی رابطه عملکرد گندم با ویژگیهای خاک، از جمله شوری و ph، پژوهشی در سال 90-91 در مزرعه نمونه ارتش استان گلستان انجام شد. در گام نخست، 101 نمونه از نیمرخ خاک مزرعه تهیه و انواع روشهای درونیابی زمینآمار (کریجینگ) با استفاده از شاخصههای آماری میزان دقت روشهای مختلف درونیابی در نرمافزارarcgis نسخه 9.3 تعیین شد. بدین منظور جهت درونیابی از روشهای کریجینگ معمولی (ok)، کریجینگ عمو...
The Landsat-7 ETM+ sensor offers several enhancements over the Landsat-4,5 Thematic Mapper (TM) sensor, including increased spectral information content, improved geodetic accuracy, reduced noise, reliable calibration, the addition of a panchromatic band, and improved spatial resolution of the thermal band. In this paper, we present some initial comparisons between Landsat-5 TM and Landsat-7 ET...
the aim of the present study was to determine the in?uence of presence or absence of corpus luteum (cl) on hormonal and metabolites composition of follicular ?uid (ff) harvested from different sized follicles and its relationship with blood serum concentrations in sanjabi ewes. ovaries and blood samples were collected from 60 clinically healthy adult ewes (sanjabi breed) 1–3 years of age in dio...
toury (1978:200) believes that translation is a kind of activity which inevitably involves at least two languages and two cultural traditions. being polite while asking for something takes place differently in different cultures and languages, therefore various strategies may be applied for making requests and also translation of them in order not to disturb or threaten the face or better to sa...
this study determined some spectral characteristics and relationship between landsat spectral reflectance and soil surface color in the arid region of iran (kashan). the study carried out in the kashan area that covers 90000 ha. consisting of mountain, hills and flood plain. enhanced thematic mapper (etm+) data collected on july 2002 were used for this research. the color composite images produ...
Merging of different data sets is often used in digital image processing to improve the visual and analytical quality of the data. The analyst may need to merge different types of data. In this process, different data such as satellite imagery from the same sensor but with different resolution, satellite imagery from different sensors with varying resolution, digitized aerial photography and sa...
Selective logging is currently a widely adopted management practice throughout the tropics. Monitoring of spatial extent and intensity of such logging is, therefore, becoming an important issue for sustainable management of forest. In spite of successful use of RS in various field of forestry, detection and quantification of selective logging is still a problem. This study explores the possibil...
در این تحقیق، تنوع ژنتیکی جمعیت آرتمیا اورمیانا و آرتمیا فرانسیسکانا ی موجود در ایران با استفاده از 5 جفت آغازگر ریزماهواره ای (af-b105tail، af-a136، apdq03tail، apdq04tail و apdq05tail) ویژه ی آرتمیا فرانسیسکانا و آرتمیا پارتنوژنتیکا بررسی شد. از 50 سیست آرتمیا ی هر یک از این دو جمعیت به صورت انفرادی dna با روش گلوله ی داغ استخراج شد. با استفاده از آغازگر ها ی پنج گانه و از طریق واکنش زنجیره ا...
based on the latest records of typhlops vermicularis merrem, 1820 from iran, this species is distributed in the northern and southern regions of the country. in this study, new records of typhlops vermicularis are presented and it is shown that distribution range of this species is extended towards the eastern and western iran, and according to the new distribution map, it can be assumed that t...
