Confectionery sunflower (Helianthus annuus L.) is one of the valuable crops which less is known about its variability. Fifty sunflower populations have been gathered from different regions of Iran and evaluated for agro-morphological traits in completely randomized design with 10 repetitions under pot conditions. The twenty traits including days from planting to flowering, days from planti...
Head motion during (1)H MR spectroscopy acquisitions may compromise the quality and reliability of in vivo metabolite measurements. Therefore, a three-plane image-based motion-tracking module was integrated into a single-voxel (1)H MR spectroscopy (point-resolved spectroscopy) sequence. A series of three orthogonal spiral navigator images was acquired immediately prior to the MR spectroscopy wa...
Honey bee queen quality is a critical factor of colony performance. Indications such qualities can manifest themselves through morphological traits as wet weight and thorax width. Improving characteristics driven in part by nutritional provision queen-cell-builder hives. We investigated the potential to improve adding coenzyme Q10 (endogenous antioxidant) caffeine (central nervous system stimul...
background: field matching problems in abutting electron fields can be managed by using spoilers. objective: the aim of this study was to design a monte carlo framework for the assessment of spoiler application in abutting electron fields. methods: a siemens primus treatment head was simulated for a 5 mev electron beam using beamnrc and dosxyznrc, egsnrc user codes. validation of beam model was...
fourteen different morphological traits in 169 and 131 cattle of oulmes-zaer and tidili, respectively were recorded and analyzed using a multivariate approach. the characters measured included heart girth, wither height, rump height, rump length, rump width, chest depth, body length, neck length, cannon circumference, ear length, ear width, head length, horn length and tail length. breed signif...
Introduction: Childhood is the most important period of human prosperity and the most basic basis for health in the later periods of life, physically, mentally, socially and cognitively. In this regard, one of the most important factors affecting children's overall development is environmental factors. The present study aimed to compare motor competence, developmental dimensions and body mass i...
the study of air infiltration into the buildings is important from several perspectives that may be noted to energy and design of hvac systems, indoor air quality and thermal comfort and design of smoke control systems. given the importance of this issue, an experimental and numerical study of air infiltration through conventional doors and windows has been explored in iran. to this end, at fir...
field programmable gate array ها آرایه های گیتی قابل برنامه ریزی می باشند که به طراح این تواناییرا می دهد تا طراحی دیجیتال خود را آنچنان که می خواهد و با هر حجم و پیچیدگی لازم، طراحی کند. یکی از زبانهای توصیف سخت افزاری این ic ها vhdl می باشد.بدین ترتیب fpga امکانات جدید را در پردازش اطلاعات بوجود آورد، یک fpga می تواند جایگزین چندین مدار سخت افزاری عادی شود.پس می توان fpga را در موارد مختلف بک...
This study provides standard information on the attributes of sperm and describes the surface structure of normal and abnormal spermatozoa of Rusa timorensis. Two fertile stags were used as the source of semen collected during the first breeding season commencing from April 5 to July 2, 2012. Another five stags were used as the source of semen collected during the second breeding season commenc...
The function of the primate hippocampus and related structures was analysed by making recordings from the hippocampus, subiculum, presubiculum, and parahippocampal gyrus in monkeys actively walking in the laboratory. Head direction cells were found in the presubiculum. The firing rate of these cells was a function of the head direction of the monkey, with a response that was typically 10-100 ti...
