(1) Neighbourhood experiments were used to compare the magnitudes of competitive effect and competitive response using all pairwise combinations of Papaver rhoeas, Triticum aestivum and Avena sativa as neighbour species, and these three species plus Chenopodium album as target species. (2) Over 79% of the variance in target weight was explained by a simple hyperbolic function of neighbour weigh...
The main purpose of this paper is to examine the effectiveness of the Quarter-Sweep Gauss-Seidel (QSGS) method in solving the dense linear systems generated from the discretization of the linear Fredholm integral equations of the second kind. In addition, the applications of the various orders of closed Newton-Cotes quadrature discretization schemes will be investigated in order to form linear ...
genus polymyxa, belongs to plasmodiophoromycota phyllum and protozoa kingdom. this fungus is a obligate endoparasite in the root cells of vascular plants. since the two species of this genus, p. graminis and p. betae are both known to carry destructive viral agents to sugar beet and poaceae. for studying the distribution of infected fields with p. betae in razavi and northern khorasan provinces...
C(4) plants have been reported to have Rubiscos with higher maximum carboxylation rates (kcat(CO(2))) and Michaelis-Menten constants (K(m)) for CO(2) (K(c)) than the enzyme from C(3) species, but variation in other kinetic parameters between the two photosynthetic pathways has not been extensively examined. The CO(2)/O(2) specificity (S(C/O)), kcat(CO(2)), K(c), and the K(m) for O(2) (K(o)) and...
In American football, impacts to the helmet and the resulting head accelerations are the primary cause of concussion injury and potentially chronic brain injury. The purpose of this study was to quantify exposures to impacts to the head (frequency, location and magnitude) for individual collegiate football players and to investigate differences in head impact exposure by player position. A tota...
