evaluation soil erosion is an important matter to protecting it from destroying in future due to the excessive use of the inherent capacity of soil and also improper management. therefore, in this study land vulnerability related to water and wind erosion of abyek for crops and pasture land has been evaluated, using raizal model as one of the microleis sub-models. morphological and physical and...

gully erosion is one of the most destructive types of channeled water erosion that removes aconsiderable volume of soil as it develops. this type of erosion consists of complex a geomorphicprocess that has been known as an indicator of accelerated soil erosion. in this research theadvancement of 25 headcuts were assessed through digital interpretation of multi-temporal aerialphotos, field obser...

Soil erosion is a crucial problem in Nepal where more than 80% of the land area is mountainous and still tectonically active. Although deforestation, overgrazing and intensive agriculture, due to population pressure, have caused accelerated erosion, natural phenomena inducing erosion, such as exceptional rains, earthquakes and glacial-lake-outburst flooding in the high Himalayas are also common...

OBJECTIVES The Oxoid M.I.C.Evaluator (M.I.C.E; Thermo Fisher Scientific) comprises an antibiotic gradient on a plastic support. We compared its performance with Etest--a similar product--using BSAC agar dilution as a reference. METHODS Parallel MIC tests were performed by M.I.C.Evaluator, Etest and agar dilution on Iso-Sensitest agar. In total, 9354 organism/strip combinations were tested by ...

Temper rolling or skin pass rolling is one of cold rolling processes composed of a horizontal pass cold rolling mill stand. In this process, the thick strip is subjected to very light reduction (0.5–4%) in thickness in the presence of high friction amplitudes. One of the basic parameters of strip rolling processes is temper rolling force. A new rolling force model has been proposed for temper r...

Rundschau 85(1): 65{70. Abstract Erosion is a complex process consisting of many components, like surface runoo, impact of raindrops, wind forces, soil, and rock mechanics, etc. Trying to integrate all these processes into a physical model seems to be hopeless. In order to understand the variety of natural shapes and patterns produced by erosion we present an integrated statistical approach. Ou...

Due to the development of scale tractor-ploughed terraces, terraces have been increasing in number, while global climate change is causing frequent extreme rainfall events Loess Plateau, resulting many terrace landslides. To study mechanism and process shallow landslides deep slip surface induced by loess hill gully area, we conducted a laboratory model test under artificial used Swedish arc st...

Current operation mode of SAR can be roughly divided into two types: strip-map mode and burst mode. The most conventional mode is strip-map mode, in which the swath width is quite limited. The other type is burst mode, which is an active option to overcome this limitation by cyclically scanning several subswaths, known as ScanSAR. In addition, Envisat ASAR has another type of burst mode, that i...
