The introduction of invasive earthworms initiates physical and chemical alterations in previously earthworm-free forest soils, which triggers an ecological cascade. most apparent step is the shift herbaceous plant community composition. However, some species, such as Arisaema triphyllum (jack-in-the-pulpit), persist where are present. It has been hypothesized that A. produces insoluble oxalate,...

Biological sensitivity to contaminant concentrations may vary substantially from species to species and the mode of toxic action may be highly selective and impair specific biological functions of the organisms. Physiological activities i.e. respiration, metabolism, feeding, breeding etc, of aquatic invertebrates are inhibited by the effects of pesticides [1]. Various workers have shown that ea...

We prove that the distance between two reflected Brownian motions outside a sphere in a 3-dimensional flat torus does not converge to 0, a.s., if the radius of the sphere is sufficiently small, relative to the size of the torus.

background: this study aimed to assess the relationship between meal frequency with mental distress and violent behavior among a nationally representative sample of iranian children and adolescents. materials and methods: the participants of this national study were 14,880 iranian students with 6 to 18 years of age. they were selected from urban and rural regions of iran by multi-stage cluster ...

Negligible amounts of urea were excreted by fresh’ earthworms &urnbricus terrestris) ; however, on fasting, the quantity of urea in the excreta increased.notably (1). The oral administration of arginine was followed by an increased elimination of urea. The excretion of urea was also augmented, to a lesser extent, by the ingestion of citrulline with certain other amino acids. The data presented ...
