Orientation and experience in the perception of form: A study with the arizona whale-kangaroo
When subjects are presented with the Arizona whale-kangaroo, an ambiguous figure, perception of the whale is more common than perception of the kangaroo. However, this difference is smaller in Australian than American subjects. Perception of the kangaroo is more orientation dependent than perception of the whale, which is perceived at all orientations of the stimulus. Together with the difference between subject populations, this effect reveals an influence of past experience on the perception of this new ambiguous figure. Perception of the whale versus the kangaroo differs in both reconstrual of parts and realignment of the object-centered reference frame. Observers report reference frame reconstruals before reference frame reversals, shedding light on the organization of object memory
Role of Non-Traditional Forages in Livestock Production in India
The paper reports a number of non-traditional forage species which form the life support system for grazing animals in normal conditions as well as scarcity periods like droughts and famines. Such species vary according to climatic and ecological conditions of India. These species play an important role in domestic livestock production as well as providing forage to the game animals. In the arid region the majority of such species are small trees and shrubs; in semi-arid regions majority of such species are shrubs, aquatic weeds and minor millets. In temperate/alpine Himalaya such species range from lichens, ferns, climbers to shrubs and aquatic weeds. The prominent species are briefly described in this paper

Modeling Quantitative Acoustic Microscopy for Layered Coatings
Multilayered ceramic and metallic coatings are receiving much attention for applications to improve the resistance to wear of surfaces. To assure the integrity of such coatings, quantitative nondestructive techniques are needed to determine the properties of coating materials and to evaluate the bonding quality of the interface between the coating and the substrate
