Abstract

Extensive laboratory tests have been conducted under six series of experiments to study the effects of two species of varying density from strength groups, thickness of constituent members, inclination of loading to the direction of grain of timber and face veneer orientation of plywood, preboring plywood, etc. Analysis of results done at different levels of derivations have revealed a definite trend in applications as to the preference of a particular plywood thickness, timber thickness and strength loss on preboring plywood but no generalized conclusion have been drawn. Bearing strength of wire nails presented for different types of joints may be safely used as designfunctions in plywood-to-wood composite structures.

Abstract

Keeping in view scientific exploitation of forest produce and to eliminate middleman, Himachal Pradesh State Forest Corporation Limited was Incorporated on 25.3.1974 and started functioning from 1.4.1974. In the Initial stage, Corporation was given management of two rosin and turpentine factories but subsequently on the basis of good performance, most of the work related to forest produce such as timber and fuelwood extraction, resin tapping, harvesting of bamboos and khair and marketing were transferred to Corporation. The Corporation was also entrusted the work of timber supply for apple packing cases. With tbe efforts of the Corporation, some headway has been made to save fir, spruce and kail timber by using poplar and Eucalyptus timber for packing cases.

Abstract

Based on the tests conducted on small clear specimens of plantation grown Acacia leucophloea. A. nilolica and A. tortilis from Mohindergarh (Haryona), their physical and mechanical properties have been reported and discussed. Although all the three species are heavier than Teak, they are not superior to Teak in several mechanical properties. Based on suitability indices, these species have been grouped as very heavy and moderately steady timbers. From strength point of view, all the three species are suitable for constructional purposes, railway sleepers, tool bandies, fence posts, agricultural implements, anvil blocks, mallet heads etc. A. nilotica and A. tortilis are also suitable for the manufaCture of dunnage pallets.

Abstract

Zinc deficiency, encountered throughout the world in man and domestic animals adversely affects the nucleic acid and protein metabolism; thereby affecting the growth promoting ability of dietary protein. Protein efficiency ratio (PER) which is the most common method used for evaluation of protein quality has been reported to be influenced by a number of nutritional factors. However, little attention has been given with respect to zinc deficiency.
