Eggs (n = 367) collected from wild Peregrine Falcon (Falco peregrinus anatum) nests between 1976 and 1990 in Colorado and New Mexico were artificially incubated and hatched. We retrospectively examined these data for variation in egg length, breadth, and initial mass of hatchlings to resolve questions about relationships among egg size, chick size, and sex; and egg size related to first and sec...

introduction: application of organic fertilizers in agricultural soils with low organic matter content is one of the best ways of nutrientsaddition to these soils. different organic fertilizers have different effects on nutrient availability in soil. moreover study of the distribution of nutrients in the soil allows investigating their mobility and bioavailability. the nutrients availability an...

In this paper considers M[X1]/G1/1, M[X2]/G2/1 , M[X3]/G3/1 general queueing system with priority services . Three types of customers from different classes arrive at the in independent Poisson process. The server follows non preemptive rule subject to working breakdown, and modified Bernoulli vacation (arbitrary) periods. After completing service, if there is no high present system. time depen...

Abstraet--A laboratory study of cadmium exchangeability revealed large differences in extractable cadmium which are dependent on the exchange solution being utilized. The standard exchange solutions employed in this study were: N NaNO3, N NaOAc, N NH4OAc, NCaCI~, and 2N CaCI2, in order of increasing Cd removal. An interpretation of the chemical behavior of Cd and an experiment with mixed sodium...
