Prediction of wheat phenology facilitates the selection of cultivars with specific adaptations to a particular environment. However, while QTL analysis for heading date can identify major genes controlling phenology, the results are limited to the environments and genotypes tested. Moreover, while ecophysiological models allow accurate predictions in new environments, they may require substanti...

BACKGROUND The possible injurious effect to the brain of heading in soccer is a matter of discussion. OBJECTIVE To determine whether standardised headings in soccer are associated with increased levels of biochemical markers for neuronal injury in cerebrospinal fluid (CSF) and serum. METHODS 23 male amateur soccer players took part in a heading training session involving heading a ball kick...

Phenological change of plants is an indication of local and regional climate change, independent of the instrumentation records and associated bias/error. Although some phenological changes have been identified for native and perennial species and used to infer climate change in various regions of the world, little has been known for changes in agricultural plants/crops. In this study, heading ...

in order to locate the qtls for plant height, peduncle length, and heading date, a set of 107 wheat doubled haploid (dh) lines derived from the cross fukuho-komugi× oligoculm was grown during the growing seasons of 2004 and 2005. a total of 36 qtls were identified based on composite interval mapping (cim) approach. all detected plant height qtl’s were stable over the two years. qtls located nea...

Humans perceive heading accurately when they rotate their eyes. This is remarkable, because (1) the pursuit eye movement makes the retinal flow more complicated; and (2) the eye rotation causes a continuous change of the heading direction on the retina. The first problem prevents a simple association of the centre of flow on the retina with the heading direction. To solve it, the brain needs to...

While it has been shown that TCP Vegas provides better performance compared to TCP Reno, studies have identified various issues associated with the protocol. We propose modifications to the congestion avoidance mechanism of the TCP Vegas to overcome these limitations. Unlike the solutions proposed in the past, our solution, named TCP Vegas-A, is neither dependent on optimising any critical para...
