Evolution of the density parameter in the anisotropic DGP cosmology
Evolution of the density parameter in the anisotropic DGP braneworld model is
studied. The role of shear and cross-over scale in the evolution of
is examined for both the branches of solution in the DGP model.
The evolution is modified significantly compared to the FRW model and further
it does not depend on the value of alone. Behaviour of the
cosmological density parameter is unaltered in the late universe.
The study of decceleration parameter shows that the entry of the universe into
self accelerating phase is determined by the value of shear. We also obtain an
estimate of the shear parameter ,
which is in agreement with the constraints obtained in the literature using
data.Comment: To apper in Int.J.Mod.Phys.D, 14 pages, 6 figure

The Young Unwed Fathers Pilot Project: Report from the Field
In 1991, P/PV designed the Young Unwed Fathers Pilot Project to see if young, economically disadvantaged fathers would enter a program that provided job training, education, counseling and parenting services for up to 18 months, and if participation would lead to an increased capacity to support their children, both financially and developmentally. This report presents a detailed look at selected aspects of the lives of the young fathers before and during program participation, including their attitudes and relationships with the mothers of their children. It also evaluates employment and educational outcomes
Aquatic animals and their environment. The Constitution of the external medium, and its effect upon the blood
The relation of vitamins to the growth of young animals
The last decade of research in the field of animal nutrition has Ied to the discovery of a new class of substances in the food stuffs constituting the animal dietary. These compounds have been designated "Vitamines, Accessory Factors of the Diet, Exogenous Hormones of the Diet". They are present in infinitesimal quantities in certain articles of the diet, but their role in the metabolic cycle is one of the greatest importance. Subsequent investigation has shown that they are essential for the wellbeing and even the life of the organism itself. Without these indispensable elements the animal cell is unable to maintain its activities unimpaired, or the adolescent subject to attain normal growth. Continued deprivation leads to disease and ultimately to cessation of life. The discovery of these cornpounds was the result of a generation's work on the etiology of two diseases - Beri-beri and Scurvy. These are now known as "Deficiency Diseases". Each of these pathological conditions is due to the dietary deficiency of a specific substance, which in the case of beri-beri is known as the "Anti-neuritic Vitamin" (Funk); "Water Soluble B substance" (McCollum). In the case of scurvy this element is called the "Antiscorbutic Substance". A third factor associated with fats of animal origin has been subsequently discovered, but its deficiency results in a general malnutrition of a chronic type complicated with Xerophthalmia
