شباهت ظاهری بین گونه های برگ باریک جنس festuca l. منجر به استفاده از صفات پنهان مانند صفات تشریحی برای اهداف تاکسونومیک شده است. ساختار و آرایش بافت اسکلرانشیمی و تعداد رگبرگ ها به طوری که در برش عرضی برگ قابل مشاهده است دارای قابلیت های تشخیصی مهمی در تعدادی از اجتماعات گونه ای در جنس festuca هستند. تعداد 53 جمعیت منتخب از گونه های festuca، شامل نمونه های جمع آوری شده از سرتاسر کشور، نمونه های...
sange siyah dam is located two kilometers down the kabod khani village. the environ of ghorrve city in kurdestan province. this is an clay core dam. in this dam instrumentation is performed in three section and consist of electrical piezometers, total pressure cells, settlement cells and so on. the main objective of instrumentation is to control the behavior of dam body and foundation, end else...
This theoretical study examines the characteristics of a surface wave driven plasma monopole antenna using finite difference time domain method (FDTD) as well as commercial full wave simulator. The results show that the full wave simulator can be considered as an acceptable tool in simulation of a plasma antenna. Input impedance, radiation pattern, gain, efficiency and radar cross section of pl...
We have theoretically demonstrated that phonon heat flux can be significantly suppressed in Si and Si/SiO2 nanowires with the periodically modulated cross-section area—referred to as the cross-section-modulated nanowires—in comparison with the generic uniform cross-section nanowires. The phonon energy spectra were obtained using the five-parameter Born–von Karman-type model and the face-centere...
in this paper, a novel approximate solution to determine the nusselt number for thermally developed, slug (low-prandtl), laminar, single phase flow in channels of arbitrary cross section is presented. using the saint-venant principle in torsion of beams, it is shown that the thermally developed nusselt number for low-prandtl flow is only a function of the geometrical parameters of the channel c...
When observers face directly toward the incline of a hill, their awareness of the slant of the hill is greatly overestimated, but motoric estimates are much more accurate. The present study examined whether similar results would be found when observers were allowed to view the side of a hill. Observers viewed the cross-sections of hills in real (Experiment 1) and virtual (Experiment 2) environm...
The theoretical accuracy of the program TOPAZ0 in the large-angle Bhabha channel is estimated. The physical error associated with the full Bhabha cross section and its forward and backward components separately is given for some event selections and several energy points of interest for LEP1 physics, both for the s and non-s contributions to the cross section.

Background & objectives: Women undergoing cesarean section may have some difficulty in self-care and also the care of their baby due to post-operative pain. Therefore, the present study was conducted to determine the effect of non-pharmacological self-care training methods on pain management in women undergoing cesarean section. Methods: This quasi-experimental study was performed on 72 women c...
