Recently, A2B3 type strong spin orbital coupling compounds such as Bi2Te3, Bi2Se3 and Sb2Te3 were theoretically predicated to be topological insulators and demonstrated through experimental efforts. The counterpart compound Sb2Se3 on the other hand was found to be topological trivial, but further theoretical studies indicated that the pressure might induce Sb2Se3 into a topological nontrivial s...

Rehabilitation scientists and biomedical engineers have been investigating wheelchair propulsion biomechanics in order to prevent musculoskeletal injuries. Several studies have investigated wheelchair propulsion biomechanics; however, few have examined wheelchair propulsion stroke patterns. The purpose of this study was to characterize wheelchair propulsion stroke patterns by investigating join...

The main goal of this paper is to propose a new practical method for hydrologic soil group estimation in surface runoff process based on geomorphology facieses and slop. The determination of CN based on this method can reduce the time and cost of project. In this research the upstream rivers of Glinak Watershed have been used as a case study to examine the efficiency of proposed method with a c...

One of the problems of existing irrigation networks is seepage phenomena. Seepage problem and its control in irrigation channels is one of the most important issues in the design, construction, maintenance and operation of these channels. In this study, simulated the rate of seepage and phreatic lines in the Mianab irrigation and drainage channels located in the Karun basin using mathematical t...

The biotic recovery following the Permian/Triassic boundary mass extinction was influenced by several secondary extinctions during Early Triassic, of which late Smithian crisis is most severe known for some nekto-pelagic organisms such as ammonoids. Smithian-Spathian transition characterized successive global and environmental changes, including a dramatic positive carbon isotopic excursion, oc...

An integrated hydraulic fracturing followed by waterflooding was conducted in a heterogeneous sandstone formation the Northern Shanxi Slop of Ordos Basin Western China. Water breakthrough quickly occurred, and underlying mechanism water has not been well understood. Such needs to be investigated comprehensively from spatial connectivity multilayer sand bodies characterization hydraulic-natural ...

The Study of river water quality interation with lakes and dam reservoirs is important from anexploitation point of view. When river water with different densities enters a lake or dam reservoir,underflow density current phenomenon occurs. Because of the density, so understandingdifferent arrays of this phenomenon Seems necessary for checking erosion and sedimentationprocesses and their managem...

This study was conducted on a total of 776 goats (part Central highland goat breeds Ethiopia), 306 from Boset district Oromia region and 470 were Minjar Shenkora Amhara region. A format developed by using food agriculture organization discerption list used for recording morphological traits, bodyweight linear body measurements. Both qualitative quantitative traits recorded randomly sampled matu...

In this study, we have performed a detailed analysis for the correlation between electron density ( Ne ) and temperature Te at topside ionosphere. situ measurements from four satellites been utilized, including China Seismo-Electromagnetic Satellite (CSES), Swarm A B, as well earlier Challenging Minisatellite Payload (CHAMP) satellite. To make fair comparison, only simultaneous observations CSE...
