Evaluation of watershed projects is one of the most fundamental problems in countries for future implementation planning and management of natural resources. In regard to lack of required equipment for monitoring and evaluation of watershed projects and investigation of management measures in watersheds, application of hydrologic models is an efficient tool for simulation of watershed behavior ...
writing as a productive skill requires practice in the basic sub-skills of vocabulary and grammar. in fact, grammar has been viewed as the core of programs in writing classes to help the students put the elements of sentence together and combine sentences of specific lengths to come up with an error-free work of art. conceptualizing l2 writing in this way introduces writing as a product and enc...
The relationship of lightning with rainfall and temperature is investigated on the basis of a four-year (2004– 2007) data set over the Pune region. It is found that the annual variations of stroke count and rainfall both are bimodal with the first peak value of rainfall showing a one month time lag from the first peak value of stroke count. This is attributed to the prime period of the onset ph...
the thermally stimulated discharge (tsdc) current is studied for acrylonitrile butadiene rubber (nbr) loaded with different high abrasion furnace carbon black (haf). tsdc peak appears only for higher haf contents > 60phr (70 and 80phr of haf contents), the tsdc spectra consist of a sharp peak corresponding to a peak temperature tm which is slightly shifted to higher temperature for 70phr ...
OBJECTIVES There are relatively few large studies of seasonal variation in the occurrence of stroke in patients with atrial fibrillation (AF). We investigated the seasonal variation in incidence rates of hospitalisation with stroke in patients from Denmark and New Zealand. DESIGN Cohort study. SETTING Nationwide hospital discharge data from Denmark and New Zealand. PARTICIPANTS 243 381 (m...
The transient electromagnetic disturbance generated by arcing discharge between the pantograph and catenary can pose a significant risk to safe operation of electrified railways. In order better comprehend its properties, pantograph–catenary generating device is designed simulate phenomenon with moving electrodes in this experimental investigation. effects applied voltage, gap distance, relativ...
it is not possible to understand developments of a country’s culture and civilization without knowing his believes and myths. whether it is north or south, east or west, planes or mountains, sahara or deserts, here in iran every corner includes valuable and precious treasures which are known all over the world, and cultural – historical objects which are found here adorn all well known museums...
Flood hydrograph simulation is affected by uncertainty in Rainfall – Runoff )RR( parameters. Uncertainty of RR parameters in Gharasoo catchment, part of the great Karkheh river basin, is evaluated by Monte–Carlo (MC) approach. A conceptual-distributed model, called ModClark, was used for basin simulation, in which the basin’s hydrograph was determined using the superposition of runoff generated...
Abstract Background & Aims: Hexamethylene diisocyanate is an aliphatic isocyanate and car painters are exposed to it. One of the most important disorders is occupational asthma. The aim of this study was to survey the effect of 1, 6 hexamethylene diisocyanate on the peak expiratory flow test to car painters in Isfahan. Materials & Methods: In this descriptive and a cross-sectional study the f...
