MODELING AND ANALYSIS OF A STAIR CASE LIFT FOR MATERIAL HANDLING SYSTEM

Abstract: This topic deals with the fabrication and analysis of a stair case lift, which can be use as Material Handling System. A stair case lift is a mechanical device for lifting people and wheelchairs up and down on the stairs, who may find difficulty in doing so themselves. For sufficiently wide stairs, a rail is mounted to the treads of the stairs. A chair or lifting platform is attached to the rail. A person on the chair or platform is lifted as the chair or platform moves along the rail, old age and goods are to be carried across the stair case. Stair case lift is a type of lift that can be mounted on the stair case without altering civil structure. This lift runs on electric power and consists of a motor, reduction gear box, rope drive, two rails a sliding chair. In this system we use DC motor for changing the polarity of the power supply which will make the motor run in reverse direction connected with the earlier, while the later will form the entire assembly run to in downward direction, with the help of Toggle switches and push buttons. Advantages over the conventional hydraulic lift are no civil structure and alteration is required, low cost, less bulkiness, less power, less maintenance requires. Easy design, easy installations. Can be of industrial use too. Moreover, considering some drawbacks due to weight carrying capacity completely depend upon the capacity of motor. There is lot of scope for further modification in the project as using monorail instead of two. Use of belt drive or chain drive instead of rope drive. Incorporation and automation/ timer unit which will ease the use of device. Rack and carrier arrangement for using the device for curved stair case. Use of work & roller reduction gear assembly.

Thiazole substituted [1,2,3] Triazole: Synthesis and antimicrobial evaluation

640-649Novel hybrid molecules containing thiazole and triazole moieties have been efficiently synthesized and characterized by spectroscopic techniques such as IR, NMR, mass spectrometry and elemental analysis. The synthesized hybrid molecules have been screened for their antimicrobial activity against bacterial as well as fungal strains. The minimum inhibitory concentrations have been determined. The investigation of antimicrobial screening data has revealed the most of the compounds exhibited moderate to good microbial activity

Photodynamic therapy for endodontic treatment of primary teeth: Original research article

Background: Tooth decay and traumatic dental injuries are the main causes of pulp inflammation in primary teeth. The present study was conducted on photodynamic therapy for endodontic treatment of primary teeth. Materials & Methods: 40 primary anterior teeth with pulp necrosis were divided into 2 groups: Group I, conventional root canal therapy and group II, conventional root canal therapy combined with antimicrobial PDT. Each group with 20 patients. Microbiological samples of the intra-canal content were taken using paper cones. Results: Group I & II had 19 boys and 9 girls and 8 boys and 12 girls respectively. Colony-forming units (CFU/mL) before and after treatment in group I at sample 1, 2, 3, 4, 5, 6, 7, 8, 9& 10 were 94000 and 0, 87040 and 2433, 14530 and 0,154231 and 4500, 123145 and 3200, 28453 and 550, 110232 and 1250,112456 and 3100, 43294 and 0 and 142945 and 1955 respectively. CFU before and after treatment in group II at sample 1,2,3,4,5,6,7,8,9 &10 were 194000 and 248,187040 and 2450,24530 and 0, 254231 and 4200,23140 and 300,38453 and 430,120232 and 1280, 212438 and 3600,143294 and 0 and 242940 and 1924 respectively. Conclusion: Conventional treatment combined with antimicrobial PDT found to be equall
