This study makes use of online teaching in this environment and adopts it for a required computer skills course with Cognitive apprenticeship (CA) Co-regulated learning (CRL) methods to improve students’ skills, motivation, experience learning. The subjects are first-year students non-information-related department at private university northern Taiwan. A total four classes comprising 111 parti...

We deene a speciication language called`timed CRL'. This language is designed to describe communicating processes employing data and time. Timed CRL is the successor of CRL 17]. It diiers in two main aspects. It is possible to make explicit reference to time using a newàt' operator; p,t is the process p where the rst action must take place at time t. Furthermore, a distinction has been made bet...

The Escherichia coli Crl protein has been described as a transcriptional coactivator for the stationary-phase sigma factor sigma(S). In a transcription system with highly purified components, we demonstrate that Crl affects transcription not only by the Esigma(S) RNA polymerase holoenzyme but also by Esigma(70) and Esigma(32). Crl increased transcription dramatically but only when the sigma con...

reproduction in domestic animals, as a major source of food and other products for human, has greatimportance and study of related subjects including sex differentiation and gonadogenesis during fetal life can solve many questions on normal development and various disorders of urogenital system. since studies on sex differentiation in goat fetus are scarce, this study was performed. twenty-five...

AIMS The aim of this study was to assess the feasibility and accuracy of fetal gender assignment by transabdominal ultrasound at 12-14 weeks of gestation. METHODS Fetal gender assessment was performed in 1222 singleton pregnancies. In all fetuses the crown-rump length (CRL) was measured and the genital area of the fetus was examined in the mid-sagittal plane. The result of ultrasound examinat...
