previous studies have aimed at testing a hypothesis but the present study is data-first research in which researcher tries to form a theory from data rather than the use of data to test a hypothesis. this study aims at exploring teachers perceptions of the strengths and weaknesses of the current syllabus for college preparatory course. eight experienced teachers were selected to collect data du...
The variation in road cross slope with service life affects the pavement drainage and has an adverse effect on vehicle operation safety. This paper describes a cross-slope prediction method influenced by coupling of traffic load soil consolidation, considering characteristics embankment to cover shortage for insufficient consideration compacted embankment. First, load-induced settlement equatio...
although bearing capacity of footings on top of slopes under monotonic loadings have been investigated widely so far, safety and bearing capacity of these structures against repeated dynamic loads have not been considered well enough. in this paper, lower bound dynamic shakedown theorem in its numerical form has been employed to firstly obtain bearing capacity of strip footings on top of slopes...
abstract in a protocol analysis of second language writing from 20 adult english as a foreign language (efl) iranian students, this research observed how language-switching (l-s), i.e., first language use in l2 writing, was affected by l2 proficiency. switching interactively between first (l1) and second (l2) languages has been recognized as one of the salient characteristics of l2 writing....
Abstract The Qinghai-Tibet Railway has been operating safely for 16 years in the permafrost zone and railroad subgrade is generally stable by adopting cooling roadbed techniques. However, settlement caused degradation of embankment-bridge transition sections (EBTS) one most representative severe distresses. A field survey on 440 bridges (including 880 EBTSs) was carried out employing terrestria...
today, the route for economic development in most countries is the same as international open competitive economy. economic institutes well known that supportive public economy belonged on the past and they may compete in the global economy. it is obvious that if they have no competitive potency or not familiar with competition technique, they may be devastated. banking system aims to collect t...
In recent years, a new type of dams namely CMD, has attracted so much attention. Different amounts of cement cause a type of behavior that be somewhere between those of embankment dams and conventional concrete dams. This behavior is not perfectly clarified and its analysis, especially under dynamical loading and in nonlinear region of the material, remains unclear. In this paper, Tobetsu dam h...
In order to research the special embankment (thermosyphon embankment) damages and distribution of permafrost under Qinghai–Tibet Highway (QTH) embankment. The section K2952–K2953, which is a typical representative QTH, was chosen for detection in determine sources damages. this study, performance characteristics embankment, active layer, table found ground-penetrating radar (GPR) images were re...
