English is considered by many to be the global language of business and communication and, as such, parents educators in countries which not a native are now encouraging children study at young age. Much second teaching learning, however, does take into account real-world context within will put use. Little Bridge has developed an learning platform for students aged 6−12 years, learners acquire...

scour around bridge piers is one of the most important fields of hydraulic research. local scour around bridge piers and abutment is one of the main reasons of bridge failures. in the field of scour at the bridges, researches are more focus on scour of piers in compare with abutment. while the available information on the bridge failures required cost, the major problems are related to abutment...

this article contains the views of different scholars and their researches about allah verdi khan bridge. in this brief study two important points have been highlighted. first, who is the probable constructor of the bridge and what the references tell about it. secondly, the explanation about the grave mistakes of the foundation and completion dates of the bridge and thus argument about the exa...

killifish (aphanius sophiae) of the cheshme-ali of damghan and shour river of eshteherd were studied and compared from morphological point of view. for morphometric studies, 34 truss morphometric measurements and  10 traditional  measurements  were made for each individual. nine meristic traits were counted. multi-variate analysis of variance (manova) revealed a significant different between va...

The paper describes the results of the EU FP7 EDGI project concerning how to extend gLite VOswith public and institutional BOINC desktop grids. Beyond simply showing the integration architecture components and services, the main emphasis is on how this integrated architecture can efficiently support parameter study applications, based on the so-calledmetajob concept created by the EDGI project....

We review the recent proof of N. Takahashi’s conjecture on genus 0 Gromov-Witten invariants (ℙ2, E), where E is a smooth cubic curve in complex projective plane ℙ2. The main idea use algebraic notion scattering diagram as bridge between world E) and moduli spaces coherent sheaves Using this bridge, can be translated into manageable question about This survey based three hours lecture series giv...

A simple scheme to increase operating pulse-number and easily obtain high-quality input current waveform of three-phase diode rectifier without PWM is investigated in this paper. The topology and operation principle are described. Then, the performance is evaluated and compared with the ordinary 6-pulse rectifier by means of a 20kW setup. By referring to the experimental results, the advantages...

It is common in many countries that engineers having an academic degree in Civil Engineering are appointed responsible for different tasks related to Bridge Engineering. However, there are serious questions about whether formal university courses in civil engineering could cover the needs of a bridge engineer to fulfill his or her job successfully. Regarding the recent significant advances in t...
