In this paper we first compare Parikh’s condition to various pumping conditions ~ BarHillel’s pumping lemma, Ogden’s condition and Bader-Moura’s condition; secondly, to interchange condition; and finally, to Sokolowski’s and Grant“s conditions. In order to carry out these comparisons we present some properties of Parikh’s languages. The main result is the orthogonality of the previously mention...

This paper presents feasibility tests for scheduling instances of real-time jobs on uniform multiprocessor platforms. In a uniform multiprocessor, each processor has an associated speed – a job executing on a processor of speed s for t time units performs s × t units of work. Two feasibility tests are presented. First, a sufficient condition is presented – whenever this condition holds the jobs...

The condition of minimum deviation (MD) by a transparent optically isotropic prism is re-derived, and expressions for the intensity transmittances T(p)(theta) and T(s)(theta) of an uncoated prism of refractive index n and prism angle alpha for incident p- and s-polarized light and their derivatives with respect to the internal angle of refraction theta are obtained. When the MD condition (theta...

Methods Nineteen able-bodied subjects walked four different conditions (control, effusion, pain, and pain+effusion), with a week between each condition. We used previouslyused injury models of pain [1] and joint effusion [2] to the right side of the knee. The control condition consisted of no injection. For each condition, subjects completed three walking trials at three times: precondition (pr...

Peptide-thioester is a pivotal intermediate for peptide ligation and N-, C-terminal cyclization. In this study, desired pathway and the side products of two C-terminal handles, hydroxyethylthiol (HET) and hydroxypropylthiol (HPT) are described in different conditions as well as kinetic studies. In addition, a new mechanism of C-terminal residue racemization is proposed on the basis of different...

2 Ibid. Five years ago, in the immediate post-conflict period, Afghanistan’s health services were in a deplorable state. Based on relatively scant information available at the time, the situation appeared chaotic. Capacity in both public and private sectors was quite limited and the outlook for the future was unclear. The AREU Issues Paper published in July 2002 noted vast differences across th...
