The shoot2.0 package implements an indirect shooting method for optimal control problems. It is speci cally designed to handle control discontinuities, with an automatic switching detection that requires no assumptions concerning the number of switchings. Special care is also devoted to the computation of the Jacobian matrix of the shooting function, using the variational system instead of clas...

BACKGROUND Practising target-shooting sport requires focused attention and motoric steadiness. A previous non-controlled pilot study suggests that children with impairing symptoms of attention-deficit/hyperactivity disorder (ADHD) benefit from participating in target-shooting sport in local shooting associations, as rated by parents and teachers. This study aims at examining if, and to which ex...

Keywords: Adé lie penguin begging biparental care breeding effort chick compensation Pygoscelis adeliae In biparental species, the response of parents when their mates are disadvantaged is highly variable. Moreover, experimental studies on parental effort have mainly focused on short-lived birds whose breeding constraints largely differ from those of long-lived species such as seabirds. We inve...

meet the needs of handicapped children. In its almost poetic statement of goals, Public Law 94142 reflects a movement to develop programs designed to meet each handicapped child’s unique educational needs, &dquo;in order to help each child become all he is capable of being.&dquo; The thrust of the Education for All Handicapped Children Act is to provide each youngster, with the &dquo;least rest...

INTRODUCTION International studies have shown blood lead at levels causing health concern in recreational indoor shooters. We hypothesized that Danish recreational indoor shooters would also have a high level of blood lead, and that this could be explained by shooting characteristics and the physical environment at the shooting range. MATERIAL AND METHODS This was an environmental case study ...

The aim of this study was to investigate the level of vision impairment (VI) that would reduce performance in shooting; to guide development of entry criteria to visually impaired (VI) shooting. Nineteen international-level shooters without VI took part in the study. Participants shot an air rifle, while standing, toward a regulation target placed at the end of a 10 m shooting range. Cambridge ...
