SURFACE MODIFICATION OF RING-TRAVELER OF TEXTILE SPINNING MACHINE FOR SUBSTANTIALITY

In this report, a study of the wear mechanisms involved in spinning Ring and Traveler of textile industry have been presented. These components, after surface processing with various coatings techniques, were analyzed on the test rig to analyze the wear mechanism. The objective was accomplished by comparing various plasma sprayed coatings on E52100 steel pins using a Pin-on-Disc machine. The surface morphology as well as mechanical properties of the deposited coatings namely WC-Co-Cr, Al2O3+TiO2 (Alumina-Titania) and Cr3C2NiCr, as well as uncoated E52100, were comparatively studied. This study elucidates towards improving the working life of the Ring in a Textile mill while spinning operation. An X-ray diffractometer (XRD) and Scanning Electron Microscope (SEM) was employed to characterize the unworn and worn surfaces of the specimens. The study revealed that the wear rate of Plasma sprayed thermal coatings enhanced with augmenting load. The Plasma sprayed WC-Co-Cr, Cr3C2NiCr, Al2O3+13TiO2 coatings developed on workpiece pins exhibited a notable decrease in volume loss of the material as compared to uncoated E52100 substrate. WC-Co-Cr coating turned out to be the best performer in terms of lowest cumulative volume loss among all the variants of coatings

To determine the prevalence of oral mucosal lesions and their association with pattern of tobacco

Aim: To determine the Prevalence of Oral mucosal lesions and their association with Pattern of tobacco. Methods: Following ethical approval, a descriptive, cross sectional research with 200 participants was done at the department of oral pathology. Individuals aged 16 and up who visited the research location and were consulted for wilful involvement in the study were included. Personal interviews were used to collect demographic information as well as tobacco use status utilising a selfdesigned proforma. Tobacco consumption habits were broadly classified into four categories based on the following criteria: smokers were those who reported daily or less than daily use of smoked form of tobacco without use of smokeless tobacco, whereas smokeless tobacco users were those who reported daily or less than daily use of smokeless tobacco without use of smoked form of tobacco. Individuals who used both forms throughout the research were classified as dual users, whereas those who never used tobacco or had a history of quitting one or both kinds were classified as nontobacco users. Results: The study population consisted of 100 people, 70 percent of whom were men and 30 percent of whom were females, with a mean age of 47.41 10.52 years

Not AvailableSouth American Tomato moth, Tuta absoluta (Meyrick), was reported as a new invasive pest on tomato from Ludhiana and Patiala districts of Punjab, India during 2016-17. The molecular identification of the pest was based on the core principle of generating DNA barcode using mitochondrial cytochrome c oxidase 1 (mt COI) gene. Though the incidence observed was very low on tomato from the surveyed areas during the observational period, considering the severity of the pest in other states, and its ability to spread rapidly into newer tomato growing areas, there is a need for constant vigil on the pest, for preventing its further spread within and the adjoining the states of Punjab.Not Availabl

Management of coronary disease in patients with advanced kidney disease

BACKGROUND Clinical trials that have assessed the effect of revascularization in patients with stable coronary disease have routinely excluded those with advanced chronic kidney disease. METHODS We randomly assigned 777 patients with advanced kidney disease and moderate or severe ischemia on stress testing to be treated with an initial invasive strategy consisting of coronary angiography and revascularization (if appropriate) added to medical therapy or an initial conservative strategy consisting of medical therapy alone and angiography reserved for those in whom medical therapy had failed. The primary outcome was a composite of death or nonfatal myocardial infarction. A key secondary outcome was a composite of death, nonfatal myocardial infarction, or hospitalization for unstable angina, heart failure, or resuscitated cardiac arrest. RESULTS At a median follow-up of 2.2 years, a primary outcome event had occurred in 123 patients in the invasive-strategy group and in 129 patients in the conservative-strategy group (estimated 3-year event rate, 36.4% vs. 36.7%; adjusted hazard ratio, 1.01; 95% confidence interval [CI], 0.79 to 1.29; P=0.95). Results for the key secondary outcome were similar (38.5% vs. 39.7%; hazard ratio, 1.01; 95% CI, 0.79 to 1.29). The invasive strategy was associated with a higher incidence of stroke than the conservative strategy (hazard ratio, 3.76; 95% CI, 1.52 to 9.32; P=0.004) and with a higher incidence of death or initiation of dialysis (hazard ratio, 1.48; 95% CI, 1.04 to 2.11; P=0.03). CONCLUSIONS Among patients with stable coronary disease, advanced chronic kidney disease, and moderate or severe ischemia, we did not find evidence that an initial invasive strategy, as compared with an initial conservative strategy, reduced the risk of death or nonfatal myocardial infarction

Health status after invasive or conservative care in coronary and advanced kidney disease

BACKGROUND In the ISCHEMIA-CKD trial, the primary analysis showed no significant difference in the risk of death or myocardial infarction with initial angiography and revascularization plus guideline-based medical therapy (invasive strategy) as compared with guideline-based medical therapy alone (conservative strategy) in participants with stable ischemic heart disease, moderate or severe ischemia, and advanced chronic kidney disease (an estimated glomerular filtration rate of <30 ml per minute per 1.73 m2 or receipt of dialysis). A secondary objective of the trial was to assess angina-related health status. METHODS We assessed health status with the Seattle Angina Questionnaire (SAQ) before randomization and at 1.5, 3, and 6 months and every 6 months thereafter. The primary outcome of this analysis was the SAQ Summary score (ranging from 0 to 100, with higher scores indicating less frequent angina and better function and quality of life). Mixed-effects cumulative probability models within a Bayesian framework were used to estimate the treatment effect with the invasive strategy. RESULTS Health status was assessed in 705 of 777 participants. Nearly half the participants (49%) had had no angina during the month before randomization. At 3 months, the estimated mean difference between the invasive-strategy group and the conservative-strategy group in the SAQ Summary score was 2.1 points (95% credible interval, 120.4 to 4.6), a result that favored the invasive strategy. The mean difference in score at 3 months was largest among participants with daily or weekly angina at baseline (10.1 points; 95% credible interval, 0.0 to 19.9), smaller among those with monthly angina at baseline (2.2 points; 95% credible interval, 122.0 to 6.2), and nearly absent among those without angina at baseline (0.6 points; 95% credible interval, 121.9 to 3.3). By 6 months, the between-group difference in the overall trial population was attenuated (0.5 points; 95% credible interval, 122.2 to 3.4). CONCLUSIONS Participants with stable ischemic heart disease, moderate or severe ischemia, and advanced chronic kidney disease did not have substantial or sustained benefits with regard to angina-related health status with an initially invasive strategy as compared with a conservative strategy
