Influence of winding parameters on yarn content and package geometry of wound packages

492-496This study is aimed at evaluating the step-precision assembly winding in terms of its potential to accommodate maximum yarn content on a given size of tube. The influence of various parameters related to step-precision winding on yarn content and package geometry of a close step-precision wound package has been studied. The outcome of this study is presumed to be very useful to manufacturers of winding as well as buyers of assembly winding systems. Step-precision winding parameters, like coil angle at start, angle up to which it is allowed to change and the number of diamonds along the circumference (Y value), influence yarn content on package; lower values of start angle and Y but higher value of change angle give increased yarn content. At the same time, it is also observed that the package with lower start angle and higher change angle give greater projection of package side flanks

Ginkgo biloba for the treatment of vitilgo vulgaris: an open label pilot clinical trial

<p>Abstract</p> <p>Background</p> <p>Vitiligo is a common hypopigmentation disorder with significant psychological impact if occurring before adulthood. A pilot clinical trial to determine the feasibility of an RCT was conducted and is reported here.</p> <p>Methods</p> <p>12 participants 12 to 35 years old were recruited to a prospective open-label pilot trial and treated with 60 mg of standardized <it>G. biloba </it>two times per day for 12 weeks. The criteria for feasibility included successful recruitment, 75% or greater retention, effectiveness and lack of serious adverse reactions. Effectiveness was assessed using the Vitiligo Area Scoring Index (VASI) and the Vitiligo European Task Force (VETF), which are validated outcome measures evaluating the area and intensity of depigmentation of vitiligo lesions. Other outcomes included photographs and adverse reactions. Safety was assessed by serum coagulation factors (platelets, PTT, INR) at baseline and week 12.</p> <p>Results</p> <p>After 2 months of recruitment, the eligible upper age limit was raised from 18 to 35 years of age in order to facilitate recruitment of the required sample size. Eleven participants completed the trial with 85% or greater adherence to the protocol. The total VASI score improved by 0.5 (P = 0.021) from 5.0 to 4.5, range of scale 0 (no depigmentation) to 100 (completely depigmented). The progression of vitiligo stopped in all participants; the total VASI indicated an average repigmentation of vitiligo lesions of 15%. VETF total vitiligo lesion area decreased 0.4% (P = 0.102) from 5.9 to 5.6 from baseline to week 12. VETF staging score improved by 0.7 (P = 0.101) from 6.6 to 5.8, and the VETF spreading score improved by 3.9 (P < 0.001)) from 2.7 to -1.2. There were no statistically significant changes in platelet count, PTT, or INR.</p> <p>Conclusions</p> <p>The criteria for feasibility were met after increasing the maximum age limit of the successful recruitment criterion; participant retention, safety and effectiveness criteria were also met. Ingestion of 60 mg of <it>Ginkgo biloba </it>BID was associated with a significant improvement in total VASI vitiligo measures and VETF spread, and a trend towards improvement on VETF measures of vitiligo lesion area and staging. Larger, randomized double-blind clinical studies are warranted and appear feasible.</p> <p>Trial Registration</p> <p>Clinical trials.gov registration number <a href="http://www.clinicaltrials.gov/ct2/show/NCT00907062">NCT00907062</a></p

UTILISATION OF STEEL SLAG IN ROADS OF MARATHWADA REGION

MIDC Jalna is declared as steel zone in Marathwada region of Maharashtra. There are about 38 steel rolling mills and 10 Billet/Ingot mills, producing 60,000 tonnes Billets/ Ingots every day, wasting 20% i.e.12000 tonnes of steel slag. This slag is crushed; steel is again extracted from the slag, which is held in pores in the slag. About 18% steel slag of it has been wasted (1% finer slag and 1% steel). After studying the properties of steel slag by geotechnical engineering point of view, the engineering properties of slag are too similar as compared to the natural aggregates. Properties like gradation, impact value, crushing value, abrasion value of aggregate are within limits of the MoRTH. Also the CBR value is found more than that of the natural aggregate. By utilizing this slag in roads, the waste material will be used and slag won’t cause any harmful impact on the environment

An Analysis of Awareness and Utilization of Contraceptives Amongst Married Woman Attending a Tertiary Care Hospital in Maharashtra, India

Introduction: It’s a cross sectional observational study conducted in outpatient clinic of Obstetrics and gynecology (OBGY) of Government medical college, Akola, Maharashtra between July-December 2013. Methods: 200 married women between 20-45 yrs were interviewed with predesigned questionnaire. Effort was made to identify reasons for wide gap between the awareness and usage of birth control and spacing methods among women. Results: All women knew at least one method of contraception but 48% were using some sort of contraception. Most known method was female sterilization, least known were injectables and male sterilization. Common method chosen was female sterilization (70.8%). None adopted male sterilization. Reasons for not using contraception were desire to have child (25%), desire for boys (13.4%), worried about side effect (16.3%), opposition from family members (11.5%), felt pregnancy was naturally spaced (11.5%), no specific reasons (10.5%), couldn’t avail contraceptive facilities (5.7%), inconvenient to use (5.7%). Conclusion: Educational and motivational activities from doctors and health workers are needed to promote the use of contraception
