This study investigates the role of man-made disturbance on on nitrogen and phosphorus nutrient storage by herbaceous species in Gall Oak stands of Lorestan province. In order to do this study, two sites with the same physiographic and ecological conditions and different land uses were selected. Multiscale sampling plots were used randomly in each site to collect data on forest floor vegetation...
Non-equi l ibr ium ni trogenat ion of transition-metal rich rare-earth intermetallics can be used to increase the nitrogen content beyond its equilibrium concentration. For example, nitrogenation of S m 2 F e l 7 using ammonia yields volume expansions up to 8.3 vol %, which correspond to a composition S m 2 F e 1 7 N x with x = 4. This effect is related to catalytic action at the metal surface ...
1. The liver of the dog in which necrosis has been produced by injection of haematoxic immune sera is characterized in the less marked forms by a storing up of nitrogen in the persisting living cells, while in the diffuse forms the total nitrogen content is but slightly above the normal. This last is to be explained by the great diminution in persisting liver substance which limits the power of...
the total nitrogen content of three barley cultivars: cehada capa (resistant at 25ac), cl 1243 (resistant at 5°c) and rika 1 (susceptible at all temperatures) to puccinia hordei was determined and compared in healthy and infected plants at 5° and 26°c. the results indicate that the total nitrogen content of cv. cehada capa leaves was greater than that of cl 1243 and rika 1 and that of cl 12...
