Control of hand transmitted vibration through development and analysis of a human hand-arm-isolator model

Investigates hand-held power tool vibration transmitted to the operator's hand and arm. A vibration isolator, based upon the concept of energy flow divider, is proposed and analyzed for its potential benefits in reducing vibration

Incidence of Lower Limb Fractures among Rehabilitated Chronic Traumatic Spinal Cord injury patients at T10 Neurological Level and Below

OBJECTIVES: 1. To find the incidence of fractures among rehabilitated chronic traumatic SCI patients at T10 neurological level and below. 2. To identify the people who are functionally ambulating after rehabilitation training, risk of falls, benefits associated with functional walking. METHODS: Its a cohort study. Seventy patients were enrolled for a period of one year from 2017 – 2018. Detailed questionnaire and clinical examination were done to find out the outcomes. Students t-test for continuous variables and Chi-square test for categorical variables were done. RESULTS: No incidence of fractures noted in either groups. • 57.14% of the participants are functionally walking following the rehabilitation training in the study. • Non walkers are more at risk of falls than walkers. CONCLUSION: The background of conducting this study was to compare with the existing evidences and literatures, that the incidence of fractures after spinal cord injury post rehabilitation in our population is less. There has been a paradigm shift in the people who are functionally walking to a permanent non walker status in the current scenario . The attempt made in this study will bring much scope in bringing more awareness to the patients, doctors, therapists and the social workers

Process Modeling of a Wire Saw Operation

Multicrystalline (MC) silicon solar cells are manufactured from bread-loaf sized ingots of solar-grade silicon by means of a multi-wire saw. In a typical wire saw system, MC ingots are sliced with an area of 100x100 mm2 and the latest wire saw systems can achieve thicknesses down to 300 microns. What makes this a challenging simulation problem is the wide range of timescales that characterize the overall cutting process. The slowest dynamics are associated with the evolution of the cut, which is described by a spatially dependent differential equation in time and in which the cutting rate is modeled much in the same manner as the Chemical Mechanical Planarization (CMP) process. The goal is to understand the physical mechanisms that limit how thin the wafers can be cut and to determine the sensitivity of cutting time and cutting rate based on process parameters

Variations in Physical Characteristics of the Waters of Zuari Estuary

5-10Based on data collected over tidal cycles at 3 selected stations in Zuari Estuary, Goa, India, seasonal changes and temporal variations in hydrographic conditions were studied in relation to tidal currents. In general, temporal variations in different hydrographic parameters were minimum during summer and maximum during monsoon. Water temperature, in general, attained higher values ( >30° C) in summer and monsoon and lower values ( <27°C) in winter. Maximum range of salinity over a tidal cycle (about 16 % was observed during monsoon in middle and upstream regions of the estuary, the minimum range being in the mouth during summer (34.8 to 35.2%). Salinity structure indicated the transformation of the estuary from a mixed one during summer to a stratified one during monsoon. Compared to that at the suspended sediment load was generally high in middle and upstream regions of the estuary, where the maximum values encountered were of the order of 200 mg/litre in the monsoon. Tidal currents were, in general, stronger in middle and upstream regions than at the mouth. During monsoon, the pre-dominance of ebb flow bearing high sediment load, the probable flocculation due to large salinity variation in the downstream part and the reduction of current speed due to widening of the estuary appear to contribute to higher rate of siltation in the harbour area

Temporal and Spatial variations in Hydrographic Conditions of Mandovi Estuary

11-17Variations in temperature, salinity, suspended matter and currents at mouth, middle and upstream regions of Mandovi Estuary were studied in relation to tides for 3 seasons, viz. premonsoon, monsoon and postmonsoon. Waters attained maximum temperature of 31.5°C during premonsoon and minimum of 25.5°C during postmonsoon. Maximum salinity variation over a tidal cycle was in the middle region of the estuary during monsoon (2 to 34%) and minimum was at the mouth during premonsoon (34 to 36%). Horizontal gradient in salinity was maximum (2.0%/km) during monsoon and minimum (about 0.2%/km) during premonsoon. The estuary changed from a stratified type during the wettest season (monsoon) to a well-mixed type in premonsoon. The sediment load was generally low (<25 mg/litre) in the waters of the upstream region during postmonsoon. Higher values of suspended load were generally associated with strong currents. At the mid region of the estuary strong currents of about 150 cm/sec were encountered with flood during premonsoon and with ebb during monsoon

STUDY OF PRESCRIBING PATTERN AND USE OF ANTIBIOTIC IN THE MANAGEMENT OF WOUND INFECTION

Objective: The main objective of the study is to estimate the demographic details of patients with various wound infection and to observe the variousorganism causing infections and also to analyze the prescribing pattern of antibiotic used in wound infection.Methods: This is a prospective observational study to evaluate the prescribing pattern of antibiotics in the Department of Surgery. The study wasconducted for 4 months (April 2016-July 2016), the information was collected from the case sheets, and the data were analyzed using Microsoft Excel.Results: In this study, males were higher than females consisting of 64.5% of the total sample size. In wound infection, diabetic foot ulcer wasfound to be a major problem. It can be observed that antibiotics were prescribed for all of the patients with cefotaxime being prescribed the most asmonotherapy. Cefotaxime+metronidazole were commonly prescribed as dual therapy. Multivitamins, antiulcerants were other major drugs providedin the supportive care. With reference to the culture sensitivity test, the major organism isolated was Staphylococcus aureus.Conclusion: An important consideration is needed in prescribing antibiotic therapy. The utilization of culture sensitivity studies are limited andmost antibiotic selection is empirical, so proper evaluation and monitoring is needed by the health-care professionals to select the appropriate one topromote the rational use of antibiotics.Keywords: Diabetic foot ulcer, Wound sepsis, Burns, Surgical site infection, Antibiotics.Â
