In the Midwest, signi cant interannual to decadal variations in precipitation and stream ow have been observed over the latter part of this century. Yet in studies of precipitation frequency, engineers and hydrologists assume that natural climate variability does not a ect the probability distribution of extreme precipitation. A regional approach is used to test this assumption for extreme prec...
in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...
Abstract Estimates of observed long-term changes in daily precipitation globally have been limited due to availability high-quality observations. In this study, a new gridded dataset precipitation, called Rainfall on Gridded Network (REGEN) V1–2019, was used perform an assessment the climatic at each global land location (except Antarctica). This study investigates number wet days (?1 mm) and e...
a watershed management program is usually based on the results of watershed modeling. accurate modeling results are decided by the appropriate parameters and input data. precipitation is the most important input for watershed modeling. precipitation characteristics usually exhibit significant spatial variation, even within small watersheds. therefore, properly describing the spatial variation o...
the present study investigated the effect of the two vocabulary teaching techniques in est, namely the use of translation and the use of visual aids as two separate vocabulary teaching techniques. to answer the question of the study, a pretest (michigan test) was administered to the 58 randomly selected est students at khajeh nasiredin tusi university, faculty of mechanics. after the homogeneit...
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...
