INTRODUCTION There is growing concern around the effects of concussion and sub-concussive impacts in sport. Routine game-play in soccer involves intentional and repeated head impacts through ball heading. Although heading is frequently cited as a risk to brain health, little data exist regarding the consequences of this activity. This study aims to assess the immediate outcomes of routine footb...

to evaluate interaction of salinity stress and nitrogen use methods on yield and yield components, in experiment was conducted in split plot in randomized complete block with 3 replications. treatments included: salinity of irrigation water levels 1.5, 4.4 and 7.9 ds/m as main plots, and nitrogen treatments 1. using n fertilizer at 3 stage in soil, 2. using two third n fertilizer in soil at pla...

Abstract Background and Objective Two steryl ferulates (γ‐oryzanol), that is, cycloartenyl ferulate 24‐methylenecycloartanyl ferulate, were previously isolated as biomarkers for heat stress during ripening in rice ( Oryza sativa L.). γ‐Oryzanol is also known to exert several biomedical effects, such antihyperlipidemic, antidiabetic, anti‐inflammatory, anticancer activities. In the present study...

Heading date is a critical trait for adaptation of rice to different cultivation areas and cropping seasons. We evaluated the heading dates of 1,123 chromosome segments substitution lines (CSSLs) in the genetic background of an elite rice variety Huajingxian74 (HJX74). A CSSL with the substituted segments from Zihui100 exhibited late heading under both natural long-day (NLD) and natural short-d...

in order to study the consequences of the application of mycorrhiza and azospirillum inoculants on yield and yield components of wheat cultivars, an experiment was conducted in the research station of shahid chamran university of ahvaz, iran in 2012-13. the experimental design was factorial based on randomized complete blocks design with three replications. the treatments including of mycorrhiz...

Observer translation relative to the world creates image flow that expands from the observer's direction of translation (heading) from which the observer can recover heading direction. Yet, the image flow is often more complex, depending on rotation of the eye, scene layout and translation velocity. A number of models [1-4] have been proposed on how the human visual system extracts heading from...
