Debate about the relative roles of catastrophic v. continuous processes of landform evolution is as old as the discipline of Earth Science itself. Over the last 10 years or so, research in the Earth Sciences has focussed strongly on the Earth’s surface and particularly in terms of quantifying rates of processes. This research parallels developments in geomorphology and sedimentology in the quan...

the study area, paykola anticline, is located in the southwestern part of kermanshah province. the aim of this research is to evaluate the geomorphological indexes of active tectonics in paykola anticline as well as to study the effect of tectonic in the form and direction of geomorphological landforms. to achieve the aim of study, the lithological and tectonic characteristics of study area wer...

Geomorphic parameters are very helpful as they can quickly explain the concerned area, which is going through a tectonic adjustment. For this purpose, four indices were applied to examine active tectonics in Quetta-Ziarat region. These include: sub-basins asymmetry (Af), transverse topography (T-Factor), hypsometric integral (HI) and stream-length gradient (SL). The calculation of three denoted...

The main goals of this study were to increase the data quality of the SPOT XS imagery for diVerentiation of several rock units and to expose the structural features of the southern part of the Sivas Tertiary Basin. With these aims, both edge enhancement and histogram equalized stretching Ž lters were applied to SPOT XS imagery of the southern part of the basin. Various geological observations a...

objective(s):the aim of this study was to improve flowability and compressibility characteristics of starch to use as a suitable excipient in direct compression tabletting. quasi-emulsion solvent diffusion was used as a crystal modification method. materials and methods: corn starch was dissolved in hydrochloric acid at 80˚c and then ethanol as a non-solvent was added with lowering temperature ...

hereby we report a patient with thalassemia major having extradural cord compression at t3-t9 levels due to a mass of extramedullary hematopoiesis (emh) tissue, whose treatment was successful with hypertransfusion therapy alone. the patient was a 23-year-old man who had not received regular blood transfusion since two years before admission. he suffered from paraparesis with a history of progre...

Abstract. Using digital educational resources (DERs) in science education is an effective way of promoting students' content knowledge complex natural processes. This work presents the usage resource CreativeLab_Sci&Math | Plate Tectonics, designed for exploring PhET™ Tectonics simulator, context pre-service teachers (PSTs) Portugal. The performance PSTs was analysed based on five tasks...
