this paper seeks to find out the degree of the rhetorical variation between the introduction sections of research papers published in english for international journals and those published in farsi in the area of computer sciences. to this end, a corpus of 100 farsi and 100 english research papers were collected and analyzed sentence by sentence based on swales’ 1990 cars model. the results rev...

this case study reports a rare variation of the superior laryngeal artery (sla), which is the principal arterial supply of the larynx. the knowledge of the arterial variations is essential for the surgeons to prevent blood loss and postoperative complications. during routine dissection of an adult male cadaver, a rare arterial variation in the sla was seen. in this case, the sla passed through ...

conclusions among anatomic variations, septal deviation and concha bullosa are predisposing factors for chronic sinusitis and we recommend that patients with chronic sinusitis be treated by surgical procedures. background identifying predisposing factors for chronic sinusitis is very important. objectives anatomical variation of the lateral nasal wall has been investigated in several studies an...

is referred to as the decay rate associated with a. If a is to be introduced in order to absorb an initial disturbance then one naturally wishes to strike upon that a with the least possible (most negative) decay rate. The mathematical attraction here lies in the oftnoted fact that, with respect to damping, ‘more is not better.’ More precisely, for constant a, the decay rate is not a decreasing...

The primary objective of this study was to investigate the degree of influence of Arabic vowel duration in 'emphatic' and 'non-emphatic' contexts on the production of English sequences. The specific questions asked were the following: (i) What is the average Arabic vowel duration in 'emphatic' and 'non-emphatic contexts ? (ii) Is vowel durational variation a function of the complex features of ...

This paper presents a measure of Internet “connectivity” (number of connected companies per capita) normalized by the economic “size ” of areas in the United States. We use cross sectional variation in connectivity to test some hypotheses about technology adoption. We find that areas in the South and Midwest have below average connectivity. Connectivity is also related to the living “attractive...

The use of genetically identical mice in toxicology studies can make it tricky to extrapolate findings to people. A new mouse model known as the Diversity Outbred better reflects the genetic diversity of the human population, offering intriguing possibilities for safety assessment.

Directional asymmetry (DA), the consistent difference between a pair of morphological structures in which the same side is always larger than the other, presents an evolutionary mystery. Although many paired traits show DA, genetic variation for DA has not been unambiguously demonstrated. Artificial selection is a powerful technique for uncovering selectable genetic variation; we review and cri...

We investigate the sufficient condition under which each positive b-weakly compact operator is Dunford-Pettis. We also investigate the necessary condition on which each positive b-weakly compact operator is Dunford-Pettis. Necessary condition on which each positive b-weakly compact operator is weakly compact is also considered. We give the operator that is semi-compact, but it is not bweakly. W...
