abstract to study the effect of water stress in rapeseed cultivars at the seedling stage, 10 rapeseed cultivars were evaluated at three irrigation levels [normal irrigation (control) and irrigation after depletion of 60 and 85% of available soil water]. analysis of variance showed considerable variation among cultivars. water stress reduced all of the studied morphological characteristics, espe...

abstractthis study investigates ‘repetition’ in the english translation of the arabic novel, adrift on the nile (1993). it aims to explore the communicative functions of ‘repetition’ and to see if these functions have been maintained or lost in the process of translating the novel. in addition, it seeks to find the translation strategies used in rendering ‘repetition’. to achieve this aim, a de...

introdouction: variations in root canal morphology pose a challenge for successful endodontic treatment. the root canal anatomy of the maxillary first molar has been often described as three roots with four canals (two mesiobuccal, one distobuccal, and one palatal). the occurrence of two palatal canals in one palatal root is quite rare. this report represents the case of a maxillary first molar...

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.
