this study investigated (a) the learners’ existing reading strategy repertoire, (b) the effect of instruction in reading strategies on learners’ strategic performance, and (c) the effect of explicit instruction in top-down reading strategies on reading comprehension ability of intermediate learners. the study was conducted with 40 intermediate efl learners in two groups of experimental and cont...
in this paper coupled nonlinear equations of motion of a suspended cable with time dependent tension and velocity are derived by using hamilton’s principal. a modal analysis for a stationary sagged cable is initially carried out in order to identify the dynamic system. the natural solution is directed to compute the natural frequencies and mode shapes of the free vibration of a suspended cable....
Chronic pain is multi-dimensional. At the physical level itself, beyond the nociceptive pathway, there is hyper arousal state of the components of the nervous system, which negatively influences tension component of the muscles, patterns of breathing, energy levels and mindset, all of which exacerbate the distress and affect the quality of life of the individual and family. Beginning with the p...
Objective: Down syndrome or trisomy 21 is one of the most common human chromosomal disorders that affect cognitive functions, communication and behavioral skills. At the macro level, various factors can contribute to the Down syndrome prevalence and mortality. This study aimed to investigate the association of health system functions with Down syndrome prevalence and mortality worldwide. Mater...
The purpose of this study was to analyze the effects fatigue and tension on physical characteristics abilities air traffic controllers (ATCOs) determine their influence mechanisms. A simulated experiment designed evaluate responses ATCOs in four states: alertness, fatigue, tension, tension. Thirty young male participated experiment. Fifteen parameters were collected analyzed estimate decreasing...
小規模な建物の外壁を解体する際，現場では転倒工法と呼ばれる工法が用いられている．この工法では，作業の最初に，外壁の建物外側への転倒防止のためにワイヤロープ等の引張材を外壁に設置する．次に外壁を引き倒せる程度に切り出して，外壁下部を切削し，その後，引張材を用いて外壁を引き倒している．この外壁下部の切削作業中に外壁の転倒災害が発生しており，その原因の一つに，引張材の過度な張力が考えられる．そこで，引張材の張力に関する実験を行い，転倒工法における，引張材の適切な張り方について検討した．引張材の張力とたるみの関係を調べた結果，引張材は，ややたるんだ状態に設置すれば良いことが分かった．一方で，引張材を用いて外壁を引き倒すとき，外壁下部を切削しているため，外壁下部の鉄筋が座屈する等の損傷をして，外壁が転倒する．そこで，引張材の張力と外壁下部に作用する力の関係について確認した．その結果，弾性範囲に...
