The present study deals with the estimation of the advanced spaceborne thermal emission and reflection radiometer (ASTER) data for geological application. Visible, near-infrared and short wave infrared reflectance data (9 ASTER bands) have been processed and interpreted in framework of a mapping project concerning the western margin of the Kalahari desert. A methodology has been applied to appa...
Climate change may significantly affect the hydrological cycle and water resource management, especially in arid and semi-arid regions. In this paper, output from the Providing Regional Climates for Impacts Studies (PRECIS) regional climate model were used in conjunction with the Soil and Water Assessment Tool (SWAT) to analyse the effects of climate change on streamflow of the Xiying and Zamu ...
A review of Holocene climate patterns in eastern Australia is presented on the basis of a series of high-resolution pollen records across a north-to-south transect. Previously published radiocarbon data are calibrated into calendar years and fitted with an age-depth model. The resulting chronologies are used to compare past environmental changes and describe patterns of climate change on a cale...
The authors tested 3 hypotheses regarding the antecedents and moderator influences of climate strength (CS; the degree of within-unit agreement of climate perceptions). The sample consisted of 197 work units. Social interaction among unit members showed positive, statistically significant correlations with CS in goals orientation and innovation climate. Work-unit leaders' informing behavior was...
abstract: postmethod is a newly developed pedagogy which as an alternative to method rejects the notion of good or bad methods and the concept of best method that can be generalized and appropriate for all contexts. instead, it treats each context as unique and one of a kind which cant be compared with other cases. this study is a postmethod-oriented one which investigates whether and how far t...
According to the importance of loss areas, which have embarrassed a wide region of Golestan province and its important role in formation of the sediment of Gorgan river, more accurate recognition of types of loss erosion seems essential in order to providing necessary function for erosion and sediment problems in them, specially gully erosion. So, in this study we are going to providing regress...
for a suitable irrigation programming and an efficient management, crop coefficient determination for different plant growth stages are necessary. in this investigation water requirement, single and dual crop coefficient of rosmarinus officinalis l. was determine by drainable lysimeter in a semi-arid climate condition. by using of drainable lysimeter, the exact water requirement and also kc val...
in this thesis our aim is to construct vector field in r3 for which the corresponding one-dimensional maps have certain discontinuities. two kinds of vector fields are considered, the first the lorenz vector field, and the second originally introced here. the latter have chaotic behavior and motivate a class of one-parameter families of maps which have positive lyapunov exponents for an open in...
the importance of writing as a complex skill in applied linguistics has drawn the attention of many researchers to evaluate textbooks in order to help learners gain self-sufficiency and autonomy in the field of language use and communication. investigations have shown that developments in textbooks evaluation can promote the quality of pedagogies and consequently the learning. this study attemp...
estimation of the amount of soil loss measurement of field indicators is a low-cost method, is easy to learn and can be simply applied. in order to measure and make assessment of soil loss amount by field indicators method in shahrak watershed, first map of the work units was prepared and then, measurements of the relevant field indicators were carried out within these units. then, epm model wa...
