abstract this study was conducted to evaluate the resistance of 70 genotypes of barley to powdery mildew. after preparing the samples contaminated with powdery mildew, reproduction of the spores of the fungus was conducted on susceptible cultivar afzal. the experiment was conducted with randomized block design in pot in greenhouse. seedlings were inoculated with the spores fungus in two-leaf st...

for the first time in the history of logic, afzal al-din al-khunaji has found tautologies and contradictories among the verity and actuality propositions. these have been formalized and investigated in first-order logic and it has been shown that their perpetual truth requires the assumption of ‘the presupposed existence of non-existence.’ in this paper, i investigate the tautologies in second-...

two barley (hordeun vulgare l.) genotypes, radical and cwb, with good to moderate levels of resistance to powdery mildew were crossed with a highly susceptible cultivar (afzal) to determine the genetics of resistance. the parents, fl, f2 and f3 generations of each of the two crosses, were evaluated for powdery mildew resistance in the glasshouse and field at the college of agriculture in karaj ...

deviding both the subjects and the predicates of the categorical propositions into actuality and verity, afzal al-din khunaji states the actuality-parts as adjectives, but verity-parts in three forms: as simple, as relational and as conditional. since the adjectives are formulated in modern logic by conjunction, we can formulate actuality-parts as conjunctions. verity-parts can be formulated at...

Background:Femoral shaft fractures account for 1.6% of all pediatric bony injuries..Fixation of femur fractures in children by ender's nailing is becoming widely accepted because of the lower chance of iatrogenic infection and cost .The objective of the study was to study the functional outcome,duration of union and the complications following the use of ender's nail for femoral shaft fractures...

Matching of feature vectors extracted from speech sample of an unknown speaker, with models of registered speakers is the most time consuming component of real-time speaker identification systems. Time controlling parameters are size and count of extracted test feature vectors as well as size, complexity and count of models of registered speakers. We studied vector quantization (VQ) for acceler...

band, laparoscopic sleeve gastrectomy, and Roux-en-Y gastric bypass. Although these procedures have been shown to achieve sustained weight loss and decreased mortality and morbidity, they can also cause unintended effects on the esophagus involving gastroesophageal reflux disease and esophageal motility. Our endoscopy column also involves bariatric procedures. Dr Christopher C. Thompson discuss...

A key goal of empirical research in software engineering is to assess practical significance, which answers the question whether observed effects some compared treatments show a relevant difference practice realistic scenarios. Even though plenty standard techniques exist statistical connecting it significance not straightforward or routinely done; indeed, only few studies principled and system...
