This chapter analyzes the adequacy of two university education models according to their Information Communications Technology (ICT) usage: One model is based on the use of ICT as a cornerstone and a cohesive element of the teaching-learning process, whereas the other considers ICT a mere teaching support tool. The preliminary results obtained from a review of case studies reveal that ICT use i...
methodology non-native participants in this study were sixty ba students majoring in english literature and teaching english as a foreign language at khayyam university of mashhad. they were senior students, between 21 to 24 years old, who had studied english for at least three and a half years and had passed several courses including grammar, reading, conversation, and writing. this was assum...
We present high-resolution X-ray spectra of the nearby, multiple T Tauri star (TTS) system Hen 3-600, obtained with the High Energy Transmission Grating Spectrograph (HETGS) aboard the Chandra X-ray Observatory (CXO). Both principle binary components of Hen 3-600 (A and B, separation 1.4) were detected in the zeroth-order CXO/HETGS X-ray image. Hen 3-600-A — the component with a large mid-infra...
Hen antigonococcal lipopolysaccharide hen serum was used in a simple slide agglutination test for the identification of Neisseria gonorrhoeae from primary isolates.
In this article, we present the continuing work on a SARS model without quarantine by Hsu and Hsieh [Sze-Bi Hsu, Ying-Hen Hsieh, Modeling intervention measures and severity-dependent public response during severe acute respiratory syndrome outbreak, SIAM J. Appl. Math. 66 (2006) 627–647]. An “acting basic reproductive number” ψ is used to predict the final size of the susceptible population. We...
In a recent account of methods of obtaining best-fit parameters of the parameters V and Km of the Michaelis-Menten equation, Tseng & Hsu (1990) appear to have misunderstood the method used by Lineweaver & Burk (1934), and to have overlooked much of the work done since 1934. The Michaelis-Menten equation represents the observed rate of v of an enzyme-catalysed reaction in terms of the two parame...
Different stocking densities (SDs) or space allocations are being practiced in commercial laying-hen operations as an attempt to improve hen welfare. Information concerning the impact of SD on accumulated manure properties (e.g., moisture content) and thus ammonia (NH3) emissions is limited in the literature. Bird SD affects the amount of manure per unit of accumulated manure surface area, whic...
The objective of this observational field study was to investigate the effect of an alternative intermittent lighting program (13L: 5D: 1L: 5D – Trt) vs. standard lighting program (16L: 8D – Ctrl) on production performance of laying-hen parent flocks. Two houses of 15,000 Hy-Line brown parent-stock hens each were used for the comparative study. Hen-day egg production (HDEP), eggs per hen ho...
Microbial food safety of eggs has not been thoroughly investigated in Egypt. Pseudomonas species are among the most ubiquitous bacteria in the environment that may also contaminate eggs. To investigate the microbial burden of Pseudomonas species in eggs, one hundred composite samples (6 eggs in each) of table hen and duck eggs were prepares after they were collected from different shops and sup...
