Comparative Clinical Evaluation of Coronally Advanced Flap (CAF) With or Without Platelet-Rich Fibrin (PRF) Membrane in the treatment of Isolated Gingival Recession: Six Months Randomized Controlled Study

The present study involved a comparative clinical evaluation of CAF with or without PRF membrane in the treatment of isolated gingival recession. The study population comprised of 20 subjects each with one Miller’s class I or II buccal recession defects. After randomization the control group was treated with CAF alone and the test group using CAF combined with PRF membrane. Clinical parameters like Gingival index (GI), Plaque index (PI), Recession depth (RD), Recession width (RW), Probing depth (PD), Clinical attachment level (CAL), Width of keratinized tissue (WKT) and Gingival thickness (GTH) were assessed at baseline, 3rd and 6th month. The data thus obtained were statistically analyzed using SPSS for Windows (version 16.0). From this randomized, controlled clinical study, the following conclusions have been elucidated, 1. CAF with and without the addition of PRF membrane yielded favorable clinical outcome in treating isolated gingival recession. 2. When comparing between the groups, there was no additional benefit by combining PRF with CAF in terms of Mean root coverage (MRC), Clinical attachment level (CAL) gain and Width of keratinized tissue (WKT) at 6th month. 3. With the addition of PRF membrane to CAF there was a statistically significant (p<0.01) increase in Gingival thickness (GTH) at 6th month. Within the limits of this study, it is important to emphasize that, the increased gingival thickness (GTH) obtained with PRF membrane and its influence on preventing further recession, should be evaluated with the studies involving larger number of samples and longer follow-up periods

Low voltage electric potential as a driving force to hinder biofouling in self-supporting carbon nanotube membranes

© 2017 Elsevier Ltd This study aimed at evaluating the contribution of low voltage electric field, both alternating (AC) and direct (DC) currents, on the prevention of bacterial attachment and cell inactivation to highly electrically conductive self-supporting carbon nanotubes (CNT) membranes at conditions which encourage biofilm formation. A mutant strain of Pseudomonas putida S12 was used a model bacterium and either capacitive or resistive electrical circuits and two flow regimes, flow-through and cross-flow filtration, were studied. Major emphasis was placed on AC due to its ability of repulsing and inactivating bacteria. AC voltage at 1.5 V, 1 kHz frequency and wave pulse above offset (+0.45) with 100Ω external resistance on the ground side prevented almost completely attachment of bacteria (>98.5%) with concomitant high inactivation (95.3 ± 2.5%) in flow-through regime. AC resulted more effective than DC, both in terms of biofouling reduction compared to cathodic DC and in terms of cell inactivation compared to anodic DC. Although similar trends were observed, a net reduced extent of prevention of bacterial attachment and inactivation was observed in filtration as compared to flow-through regime, which is mainly attributed to the permeate drag force, also supported by theoretical calculations in DC in capacitive mode. Electrochemical impedance spectroscopy analysis suggests a pure resistor behavior in resistance mode compared to involvement of redox reactions in capacitance mode, as source for bacteria detachment and inactivation. Although further optimization is required, electrically polarized CNT membranes offer a viable antibiofouling strategy to hinder biofouling and simplify membrane care during filtration

Facades of Attractive Employer in Indian IT Industry

Despite advances in technology and major shifts in economy, people remain an organizations most valuable resource. Human capital and intellectual assets make a difference to the competitive advantage of the firm in a knowledge based industry. Employer Attractiveness (EA) is the prerequisite to attract and retain superior quality talent. Employer attractiveness can be defined as the envisioned benefits that a potential employee sees in working for a specific organization. This study empirically examines the elements of employer attractiveness in Information Technology (IT) industry from the perspective of current employees and determines the most attractive employer in the Indian IT industry. Results show that Indian IT employees valued economic factors, global opportunities, development factors, and application factors. Tata Consultancy Services (TCS) was the most attractive employer, followed by Infosys, Wipro, Polaris Software Lab and Hexaware.</p

Implementation of Industrial Engineering concepts in Apparel Industry to improving Productivity and it’s cost reduction

Abstract In current scenario the fashion industry (industry 4.O) needs to satisfy the various needs of customer in the aspect of quantity as well as quality of the products. In traditional methods the apparel industry used basic sewing machines for all operations with the help of man power so on that time to introduce different styles in the apparel is very difficult. In recent days the automation as well as improved techniques known as industrial engineering concepts is applicable in the field to improve productivity as well as quality to overcome the competitive market. Manufacturing of garment involves number of operations in different departments. In apparel sector to improve productivity as well as quality one must concentrate on machine, method, material and man. So the industrial engineering concepts will cover and manage the all above said factors and help to improve the productivity as well as quality of the products that will satisfies the consumer needs. This paper is going to discuss about the existing (manufacturing) methods in apparel units and help them to improve productivity by applying the one of recent techniques such as Capacity Study, Work study, Time study, Operator Performance, Follow-ups, Work-in-Progress and line balancing and they are already proven techniques to improve the productivity in different industries.</jats:p
