The purpose of this study was to evaluate different homogeneity indices for IMRT of head and neck cancers and to suggest the best representative homogeneity index for quantitative measure of dose homogeneity. In this study 3 different homogeneity indices were evaluated for 22 head and neck cancer patients receiving dynamic IMRT treatments on Clinac-DHX linear accelerator with 6 MV photon beam. ...
Rice paddies are a major source of anthropogenic nitrous oxide (N2O) emissions, especially under alternate wetting-drying irrigation and high N input. Increasing photosynthate allocation to the grain in rice (Oryza sativa L.) has been identified as an effective strategy of genetic and agronomic innovation for yield enhancement; however, its impacts on N2O emissions are still unknown. We conduct...
In order to evaluate traits related to drought stress in eight sesame (sesamum indicum L.) genotypes, two experiments were carried out in randomized complete design with three replications in the field of the Research Station of College of Agriculture, Shiraz University, Iran. The two experiments differed with respect to their irrigation regimes. Yield related traits (number of days to maturati...
Abstract Applications of plant growth regulators such as paclobutrazol (PAC) to grain maize frequently caused depressions in yield. This negative impact probably originated from treatments at an early stage during ontogenesis when the determination potential kernel number coincided with time regulator application. However, stability yield itself is high relevance, and it also key determinant fo...
A two-year study (2007-2008) was carried out to explore the effect of split application of nitrogen fertilizer on yield, dry matter and harvest index of Marfona potato cultivar in Isfahan Agricultural Research Center, Iran. A randomized complete block design with a split plot arrangement with three replications was used. The main plots were three levels of nitrogen (100, 200 and 300 kg ha-1) an...
The objective of this study was to develop a Korean version of the Assessment of Spondyloarthritis International Society-Health Index/Environmental Factor (ASAS HI/EF) and to evaluate its reliability and validity in Korean patients with axial spondyloarthritis (SpA). A total of 43 patients participated. Translation and cross-cultural adaptation of the ASAS HI/EF was performed according to inter...
The most desirable approach to improve characteristics such as yield with polygenic inheritance and genotype × environment interaction, is simultaneous selection using selection index based on related traits. This study was conducted Research Farm of Isfahan University of Technology, to compare selection indices for barley yield improvement under nitrogen stress and non stress conditions, usi...

An underlying assumption of the above parametric approach is that the process is a = Gaussian field, i.e., its statistical characteristics, including its roughness parameter (or its reciprocal, the smoothness ) ), are the same at each point in the image. The FWHM of the process should be constant in all directions and across all voxels in the image. While these assumptions are reasonable for fu...
