Comparative evaluation of postpartum versus post MTP insertion of intrauterine contraceptive device

Background: This study was planned to evaluate acceptability, safety and continuation rate of postpartum intrauterine contraceptive device (PPIUCD) and to compare it with well accepted post MTP IUCD in Indian population.Methods: This was a prospective study conducted in VMMC and Safdarjang Hospital, New Delhi, India. Copper T 380-A was inserted in 100 woman in postpartum period and in 100 woman in post MTP period. Follow up done at 6 weeks, 3 months and 6 months. Safety was assessed in terms of expulsion, IUCD failure/pregnancy rate, perforation, removal of IUCD, visibility of strings and various complain at each visit. Continuation rate along with their level of satisfaction was compared at the end of 6 months. SPSS software, Chi-square test and student T test were used for analyzing the results. P value ≤0.05 considered as significant.Results: Acceptance of post MTP IUCD was more than PPIUCD. There was statistically no significant difference in expulsion rate, removal of IUCD and various complaints. There was no case of perforation in either group. Non visibility of strings was major cause of concern and apprehension in PPIUCD group. Only one case of pregnancy was reported in PPIUCD group while no failure was reported in post MTP group. Continuation rate and level of satisfaction were comparable in both groups.Conclusions: PPIUCD is equally safe and effective as post MTP IUCD.

Modified dual osteotomy for Madelung’s deformity

Madelung’s deformity is one of the rare congenital deformities of the forearm and wrist, typically seen as positive ulnar variance and increased volar tilt due to the “Vickers” ligament. Different corrective surgical methods for this have been done in the literature. In this case of a 9-year-old Madelung’s like deformity, we have performed a modified dual osteotomy with periosteal preservation allowing natural articulation and bone to be modified, especially in a younger child. This article gives the surgical option to orthopedics for the future, especially in a younger child with severe deformity. This is a level V evidence-based therapeutic study

Robust estimation of bacterial cell count from optical density

Optical density (OD) is widely used to estimate the density of cells in liquid culture, but cannot be compared between instruments without a standardized calibration protocol and is challenging to relate to actual cell count. We address this with an interlaboratory study comparing three simple, low-cost, and highly accessible OD calibration protocols across 244 laboratories, applied to eight strains of constitutive GFP-expressing E. coli. Based on our results, we recommend calibrating OD to estimated cell count using serial dilution of silica microspheres, which produces highly precise calibration (95.5% of residuals <1.2-fold), is easily assessed for quality control, also assesses instrument effective linear range, and can be combined with fluorescence calibration to obtain units of Molecules of Equivalent Fluorescein (MEFL) per cell, allowing direct comparison and data fusion with flow cytometry measurements: in our study, fluorescence per cell measurements showed only a 1.07-fold mean difference between plate reader and flow cytometry data

FPGA based implementation of Data acquisition and processing system for MEMS based pressure sensor

Data acquisition and processing system for MEMS based sensors is an active research area. They are designed to acquire data from the sensors, process the data and transmit over a digital link to other systems. Major components in these systems are sensor, Micro Controller and a serial link. Air Data Computer is used to acquire pressure data for real time control of the Aircraft. In present systems Air Data Computer is pretty large in size. The purpose is to try to miniaturize air data computer system to a hand held device

Numerical Simulation and Dynamics of Burgers’ Equation Using the Modified Cubic B-Spline Differential Quadrature Method

In the present work, a numerical approach using the Crank–Nicolson scheme along with the modified cubic B-spline differential quadrature (CN-MCDQ) method is proposed to find the numerical approximations to Burgers’ equation. After applying the well-known Crank–Nicolson technique, Burgers’ equation is solved in this study by using the differential quadrature approach to approximate the derivatives that lead to a system of equations to be solved. When compared to other methods for obtaining numerical solutions, the proposed method is shown to be efficient and easy to implement while still providing accurate results. The obtained results are in agreement with the earlier available approaches and are even better in comparison in terms of less domain partition. Three test problems were used to evaluate the methodology, and the results are tabulated and graphically shown below

TENSILE STRENGTH OF WELDED MILD STEEL SPECIMEN ON UNIVERSAL TESTING MACHINE

The aim of my paper is to find the various properties of mild steel specimen which is welded by mainly three welding . Quality and productivity play important role in today’s manufacturing market. Now a day’s due to very stiff and cut throat competitive market condition in manufacturing industries. The main objective of industries reveals with producing better quality product at minimum cost and increase productivity. Welding is the most vital and common operation use for joining of two similar and dissimilar parts.In the present research paper an attempt is made to understand various welding techniques and to find the best welding technique for steel. Special focuses have been put on TIG , MIG , ARC welding. On hardness testing machine and UTM various characteristics such as ultimate tensile load, ultimate tensile stress, breaking point, % elongation etc. were analyzed

Classification of brain tumor using devernay sub-pixel edge detection and k-nearest neighbours methodology

Any disease can be treated only once it is imaged, detected and classified. This paper proposes a set of algorithms for classification of a brain tumor with better accuracy and efficiency. The proposal uses a JPEG format of the DICOM image fed into three stages namely pre-processing, segmentation using sub-pixel edge detection method and using the nearest neighbor methodology for the detection and differentiation of benign and malignant tumors
