ramand region is a part of qazvin province located in south west of buin-zahra. in this region, hydrothermal alterations have been extended within magmatic occurrences and therefore are mostly detectable by remote sensing techniques. altered facies could be well enhanced after applying selective principle component analysis (spca), least squares fitting method (ls-fit) and spectral angel mapper...
expensive to provide these maps with field measurements therefore it is better to use new methods. this study provides a lithological and alteration mapping units with dominant minerals based on hyperspectral images of eo1-hyperion satellite. to do so, two different zones were investigated: the cuprite-nevada and mozahem volcano in iran which have suitable conditions for our study...
The challenges in the management of diverse flora impacted by anthropogenic factors areas governed different land tenure systems are enormous notwithstanding lying a classified biodiversity hot spot region Meghalaya North- east India. attributes plant population protected like Nongkhyllem Wildlife Sanctuary (NWLS), Forest (NRF), and District Council Eco-sensitive zone (ESZ) were studied using I...
Anaplasma phagocytophilum is an obligate intracellular, Gram-negative pathogen, causative agent of Human Granulocytic Anaplasmosis (HGA). HGA usually manifests as a non-specific febrile illness, accompanied by evidence leucopenia, thrombocytopenia, and alteration in liver enzymes. Neurologic manifestations anaplasmosis are rare rarely reported. We describe 62-year-old man who developed encephal...
The aim of this research is the analysis of management ability using accounting and corporate governance criteria and also artificial intelligence. The primary independent variables in this study include regulatory variables (characteristics of corporate governance and audit committee) and accounting variables (performance and risk criteria). We took advantage of Demirjian index to measure mana...
East Salmas gneisses are located in the northernmost parts of the Sanandaj-Sirjan zone and are seen in banded and deformed with the 6 different groups of lithological diversity. Their protolith is of paragneiss type with arkosic sedimentary rock type.Texturally, they are immature. Based on this study, chemical maturation trend of protolith of the present investigated gneisses are in the arid to...
The Argash antimony ore deposit is located at south of Neyshabour and the eastern part of the Sabzevar zone. This deposit occurs within a sequence of Eocene-Oligocene volcanic-intrusion rocks. The mineralization occurs as open space filling, taking place as irregular veins, veinlets and hydrothermal breccias. The mineralogy of the veins is comparatively simple. The primary antimony-bearing mine...
بررسی روند شاخص های خشکسالی spi، rdi و sdi در استان یزد در دو دهه گذشته با استفاده از آمار ناپارامتر
خشکسالی به عنوان بلای طبیعی و پدیده ای اجتنابناپذیر در مناطق خشک و نیمه خشک که مسائل مدیریت منابع آب امری ضروری است، وقوع می یابد. در دهه های اخیر بین حوادث طبیعی که جمعیت های انسانی را تحت تاثیر قرار داده است، پدیده خشکسالی از نظر فراوانی، شدت، مدت، فضای تحت پوشش، تلفات جانی، خسارت های اقتصادی و اثر های اجتماعی دراز مدت در جامعه، بیشتر از سایر بلایای طبیعی بوده است. بررسی روند شدت خشکسالی در ...
abstract the present study investigated the effects of task types and involvement load hypothesis on incidental learning of 10 target words (tws) in junior high schools (jhss) in givi, ardabil. the tasks deployed in this study were two input-based tasks (reading plus dictionary use with an involvement index of 3, and reading plus gap-fill task with an involvement index of 2), and one output-ba...
201(5): 897-900. I g6 I .-Dogs under chloralose anesthesia show augmented reflex responses of systolic arterial pressure, mean arterial pressure, diastolic arterial pressure, and pulse rate to bilateral occlusion of the common carotid arteries over the responses of these same parameters before any a nesthesia. H yporeflexia, as indicated by these parameters, is observed when the anesthetic is c...
