in the current study, for improving quality and quantity of ‘yaghooti’ seedless grape, gibberellic acid was sprayed in four concentrations including zero (as control), 15, 25 and 40 mg/l, at three stages, and girdling treatments were carried out simultaneously with the third step of ga3 spraying at the base of fruit bearing shoots with four replications. the cluster length was significantly in...
this thesis seeks to present a critical reading of virginia woolf’s mrs. dalloway and michael cunningham’s the hours in terms of an intertextual approach, concentrating on dialogic imagination, negativity, transposition and allusion. this study attempts to evaluate cunninghams perception of woolfs life and work by adopting kristevas conception of intertextuality and her consideration of the hou...
The objectives were to investigate if partial substitution of a grazing diet with a supplemental high-starch feed during the last 12 d of gestation improved colostrum yield and neonatal activity in goat does grazing semi-arid rangeland. For the first objective, 25 pregnant does were randomly assigned to 1 of 2 treatments: 1) grazing only (control; n = 11), and 2) grazing plus 0.6 kg/d of supple...
soil compaction has become a widespread problem in the world and it is considered as one of the main factors affecting land degradation in arid and semi-arid agricultural land. the aim of this study was to investigate the effects of soil compaction on soil carbon and nitrogen sequestration, physical (aggregate stability, saturated soil moisture content, bulk density, and porosity) and chemical ...
The effect of phosphorus supplementation to ammoniated rice straw was studied. The in vitro experiment was carried out following the first stage of Tilley and Terry method. The treatments consisting of four diets were A= 50% ammoniated rice straw + 50% concentrate (control), B= A + 0.2% phosphorus (P) supplement, C= A + 0.4% phosphorus (P) supplement, and D= A + 0.6% phosphorus (P) supplement o...
In this study, the effects of four types of mulch including wood chips, municipal compost, sawdust and gravel in three different thicknesses on temperature soil, moisture and growth characteristics of two cultivars of Tagetes (Tagetes patella var Durango Bee and Tagetes erecta var Antigua) were examined in Mashhad area with semi-arid climate. The research was conducted as a split plot based on ...
this thesis is presented 10 ghz voltage controlled ring oscillator for high speed application. the voltage controlled ring oscillator was designed and fabricated in 0.13یm cmos technology. the oscillator is 7-stages ring oscillator with one inverter replaced by nand-gate for shutting down in the ring oscillator during idle mode. tri-state inverter was used to control of 126 bit vector in ri...
a phase-locked loop (pll) based frequency synthesizer is an important circuit that is used in many applications, especially in communication systems such as ethernet receivers, disk drive read/write channels, digital mobile receivers, high-speed memory interfaces, system clock recovery and wireless communication system. other than requiring good signal purity such as low phase noise and low spu...
abstract while task-based instruction is considered as the most effective way to learn a language in the related literature, it is oversimplified on various grounds. different variables may affect how students are engaged with not only the language but also with the task itself. the present study was conducted to investigate language and task related engagement on the basis of the task typolog...
in this study, the effects of weed control treatments and plant density on lentil (lens culinaris) yield and yield components as well as weed control efficacy were investigated. the study was conducted according to a split-plot arrangement based on randomized completely block design in three replicates in karaj in 2007-2008. the weed control chemical treatments in four levels (trifluralin herbi...
