Abstract Northern corn leaf blight (NCLB) is one of the most important diseases in maize worldwide. It caused by fungus Exserohilum turcicum, which exhibits a high genetic variability for virulence, and hence physiological races have been reported. Disease control based mainly on fungicide application host resistance. Qualitative resistance has widely used to NCLB through deployment Ht genes. K...

This study investigated the impact of a self-regulatory tool, the Instructional Planning Self-Reflective Tool (IPSRT), on preservice teachers’ performance, disposition, and self-efficacy beliefs regarding systematic instructional planning. Participants enrolled in an introductory educational technology course were taught how to develop an instructional plan as part of the course. An experimenta...

In a multi-battle contest, each time a player competes by investing some of her budgets or resources in a component battle to collect a value if winning the battle. There are multiple battles to fight, and the budgets get consumed over time. The final winner in the overall contest is the one who first reaches some amount of total value. Examples include R & D races, sports competition, election...

The objective of this study was to evaluate sweet potato clones for resistance to root-knot nematode, Meloidogyne incognita races 1 and 3. For each nematode physiological race, a greenhouse experiment was set up in a randomized block experimental design with three replications and six plants per plot. Fifty-eight sweet potato clones from the UFVJM germplasm bank were evaluated, plus five commer...

We present a model which encompasses pace optimization and motor control effort for runner on fixed distance. see that long races, the term behaviour is well approximated by turnpike problem, allows to define an approximate optimal velocity. provide numerical simulations quite consistent with this approximation leads simplified problem. The advantage of formulation velocity if we have data race...

Afro-Caribbean sprinters often reach high performance levels at an early age. Adolescence is a time of morphological and physiological changes. This study was designed to analyze the evolution in parameters of short sprint performance during adolescence in Afro-Caribbean boys, especially the stride number/body height ratio (SN/BH), which is at the interface of technical and morphological factor...
