In this paper we Studied the polynomial coefficients and approximation errors for functions of the form f (z) = Σ∞ k=1 qk(z)[y(z)]k-1 belong to Ls (B), the class of all functions holo- morphic on Caratheodory domain B. The lower (p, q)-order and generalized lower (p, q)-type with respect to proximate order have been characterized in terms of these polynomial coefficients and approximation errors.
Some reproductive parameters of collared pika Ochotona rufescens Gray, 1842 were studied during the winter from Ziarat Valley, Baluchistan. Out of 195 animals captured, 105 (53.8%) were males and 90 (46.2%) females. Males were bigger and heavier than non-pregnant females. Mean litter size according to embryo count was 3.6 ± 1.6 (range: 1-7 young/female), and by placental scars 4.48 ± 0.30 (range: 2-6 young/ female). Mean HBL of primiparous females was less than multiparous females. The higher fecundity rate of pika helps to attain its pest status in apple orchards.
The effects of different CdCl₂ concentrations on the growth and on certain biochemical parameters of almond seedlings (Prunus dulcis) were studied under controlled conditions in the nutrient solutions containing increasing CdCl₂ concentrations ranging from 0 to 150 µM CdCl₂. Under Cd stress conditions, damage was variable. Cadmium reduced dry matter production in leaves and roots. While chlorophyll content was severely decreased, that of leaf sugars appeared to be increased. Furthermore, leaf nutritional status seemed to be more altered than that of roots. Both in roots and leaves, there was an increase in MDA content as metal concentration increased. It may be suggested from the present study that toxic concentrations of Cd cause oxidative damage as shown by the increase of lipid peroxidation.
