A biomechanical analysis of soccer heading technique
… All Participants had at least 9 years of soccer heading experience, were currently injury free, and reported no serious head injuries. Participants were separated into two groups, frequent headers (FH) and infrequent headers (IH). They were videotaped performing 10 standing headers and were asked …

Optimal linear array heading in a directional noise field
… For a given target location, each possible heading of the array centers the ambiguous beam of the array at a different true bearing. Therefore, each heading of the array will receive a different ambient noise level. An optimal heading can be obtained which maximizes the SNR received by the …

ALTERATIONS IN POSTURAL CONTROL FOLLOWING AN ACUTE BOUT OF SOCCER HEADING
… sought to determine if an acute bout of soccer heading adversely altered postural control and pronounced self-reported symptoms of cerebral concussion. Sixteen collegiate soccer players were randomly assigned to one of two groups: control (CG) or experimental (EG). Participants either simulated …

Dissecting Earliness per se and Photoperiod heading date effects in bread wheat (Triticum aestivum)
Vernalization, photoperiod and the poorly defined earliness per se (Eps) genes regulate flowering in plants. This thesis used elite hexaploid wheat varieties and focused on an Eps QTL on 1DL, and photoperiod QTLs on 1BL and 5AL short day QTL using doubled haploid (DH) populations. Four independent …
