T-Policy in Reliability and Inventory

In this thesis T-policy is implemented to the inventory system with random lead time and also repair in the reliability of k-out-of-n system. Inventory system may be considered as the system of keeping records of the amounts of commodities in stock. Reliability is defined as the ability of an entity to perform a required function under given conditions for a given time interval. It is measured by the probability that an entity E can perform a required function under given conditions for the time interval. In this thesis considered k-out-of-n system with repair and two modes of service under T-policy. In this case first server is available always and second server is activated on elapse of T time units. The lead time is exponentially distributed with parameter  and T is exponentially distributed with parameter  from the epoch at which it was inactivated after completion of repair of all failed units in the previous cycle, or the moment n-k failed units accumulate. The repaired units are assumed to be as good as new. In this study , three different situations, ie; cold system, warm system and hot system. A k-out-of-n system is called cold, warm or hot according as the functional units do not fail, fail at a lower rate or fail at the same rate when system is shown as that when it is up.

Compensation to Workmen for Industrial Injuries

This thesis Entitled compensation to workmen for industrial injuries.Evaluation of the different forms of liability for compensating industrial injuries makes it evident that the liability under the social insurance scheme is the most befitting one, as it eliminates the problem of evasion of liability by the employer by providing for sharing of liability. Liability for compensation under the workmen's Compensation Act, 1923 and the Employees' State Insurance Act, 1948 arises only in the case of accidents, arising in the course of and out of employment. Majority of the workers, covered by the workmen's Compensation Act, have supported lumpsum payment of compensation under the Act. It appears that workers are ignorant of the cemerits of lumpsum payment. So, the workers should be properly educated by the Inspectorate, proposed above, about the comparative advantages of periodical payments. It is suggested that the workmens Compensation Act, 1923 may be amended, imposing fee upon the parties for each adjournment. It is also suggested that provision may be made in the workmens Compensation Act, 1923 for the expeditious despatch of amendments of the Workmen's Compensation Act, 1923, the Workmens· Compensation Rules, 1924 and the Schedules, made from time to time, to the comrnissioners for workmens Compensation, This will help them mete out justice to an injured workman, as required by the changes in the law. The Employees' State Insurance Act, 1948 and the Rules may be amended, requiring the employers to provide the employees with necessary information, in the vernacular language, about the employment injury benefits available under the Employees' State Insurance Act, 1948 and the formalities for obtaining the same. This will help the illiterate employees, especially the casual ones, avail of employment injury benefits. Changes in the law, on the lines suggested above, are imperative to make the system of compensation for industrial injuries prove effective and beneficial to injured workmen.

Changes in Biochemical Composition in Indian Major Carps in Relation to size

Total biochemical composition of freshwater major carps, Labeo rohita -(r9hu); Catla catla (catla); Cirrltinus tnrigala (mrigal), in relation to size was evaluated . The water soluble nitrogen fraction constituted about 21% of the tota l nitro gen . Salt so luble fraction constituted 55 - 60% of the total nitrogen. Non-protein nitrogen represented 12% of the total nit rogen in all the cases except mri gal of small size (9.36%). The insoluble connec tive tissu e contributed to 2-3 per cent of tota l nitrogen . The monounsaturated fatty acid s (MUFA) formed 31-39% of the total fatty acids and 60-68% of the MUFA in freshwat er carps was CI 8:1. The esse ntial amino acids contributed to 41 to 51% of the total amino acid s in freshwater major carps. Arom atic amino acid content was sligh tly higher compared to marine fishe s while the proportion of proline was less. Varia tions in compos ition in rela tion to size are discu ssed . The autolytic activi ty was significantly higher in small fish in all the three species
