The sharp Hα NLTE line cores of hydrogen rich (DA) white dwarfs allow their projected rotational velocities to be determined. High resolution optical spectra of 22 stars obtained with the Keck I telescope are matched by synthetic spectra computed from a grid of NLTE model atmospheres. We concentrate preferentially on hydrogen-rich white dwarfs with convective atmospheres, i.e. with Teff < 14 00...
McCall et al. (2008) KMS use Decision performance and knowledge acquisition ACT-R theory Experiment Students who enrolled in a managerial accounting class WebCT, an internetbased course portal In the short term, KMS increased decision performance, but in the long term, it did not help development of domain expertise Test scores, encoding of explicit knowledge and problemsolving skills Journal o...

We are not only in a new millennium but also a new era. A variety of terms such as the Post-Industrial Era (Huber, 1990), the Information Age (Shapiro et al, 1999), the Third Wave (Hope et al, 1999) or the Knowledge Society (Drucker, 1999) are being used to describe this epoch. However, whichever term one subscribes to, most are agreed that one of the key defining and unifying themes of this pe...
We prove that any stationary state describing an infinite classical system which is "stable" under local perturbations (and possesses some strong time clustering properties) must satisfy the "classical" KMS condition. (This in turn implies, quite generally, that it is a Gibbs state.) Similar results have been proven previously for quantum systems by Haag et al. and for finite classical systems ...
We have used the ARGUS multi–object spectrometer at the CTIO 4m Blanco telescope to obtain 2756 radial velocity measurements for 1966 individual stars in the globular cluster ω Centauri brighter than blue photographic magnitude of about 16.5. Of these, 1589 stars are cluster members. A comparison with two independent radial velocity studies, carried out by Suntzeff & Kraft and by Mayor et al., ...

diseases and emphasis on using nondrug treatments, this study was performed to assess the effect of wheat germ on lipid profile reduction among hyperlipidemia and normolipidomia students. Materials and Methods: 108 volunteer students in the age range of 21.33±2.15 years old (74 normolipidemics, 34 hyperlipidemics) were entered to the study. In addition to their typical diet, these students were...
استافیلوکوکوس اورئوس نوعی کوکسی گرم مثبت است که یکی از عوامل تورم پستان در گاو می-باشد. اغلب مزمن بوده و با درمان آنتی بیوتیکی به آسانی درمان نمی شود لذا مشکلات جدی برای تولید شیر و صنعت لبنی ایجاد می نماید (sol, 1997). تورم پستان بیماری عفونی است که در بخش تولید با هزینه های بالای مالی درمان می شود. مقاومت دارویی در گونه های استافیلوکوکوس ارئوس مثل مقاومت به بتا لاکتام ها از جمله متی سیلین شنا...
