Determinant factors affecting the trends of permanent sterilization: a decadal analysis in a tertiary care institute

Background: Permanent sterilization is a preferred method of contraception worldwide. In spite of popularization of temporary methods, it is used by 2/3rd of married women using any contraception. It has a low incidence of complications and failure rate and is cost-effective. Various socio-demographic factors play a role in acceptability of this method. It has an important role in controlling the total fertility rate.Methods: A retrospective record based analysis was done in armed forces personnel undergoing permanent sterilization operation over 11 years between 2005-2015 in a tertiary care institute. Analysis of trends in method choices of surgery, and comparison of the variables determining these choices was done. Year wise total fertility rates was calculated and the trend over 11 years was analyzed.Results: Permanent sterilization operations were performed in 2121 couples over the 11 years period. Of total operations, 1823 (85.95% with 95% confidence interval = 84.42, 87.38) were done in females and 298 (14.05% with 95% confidence interval = 12.62, 15.58) in males. Female sterilization acceptance ranged between 71.6% to 91.6% and male sterilization between 8.4%-28.4% with an increasing trend towards male sterilization acceptance over the years. Total fertility rate declined from 2.3 to 2.09 in 11 years.Conclusions: Increase in literacy rate of both the partners can positively impact the male involvement in permanent sterilization and control of TFR. This would help to stabilize India’s population growth. Also, a decline in son preference can be beneficial for decline in fertility rate.

Impact of the surface roughness on the electrical capacitance

A new hybrid approach consists to use the advantages of both systems namely the high geometric aspects of the electrodes of the ultracapacitor and the high dielectric strength of polymer materials used in dielectric capacitors. The surface roughness of the electrodes of the ultracapacitor is manufactured with nano-porous materials; activated carbon and carbon nanotubes (CNTs). Many compositions of both carbonaceous materials are tested with different insulating materials (liquid and solid) to constitute the hybrid capacitor. It appears that the capacitance increases with the carbonaceous composition: An increasing from 15 to 40% is observed as compared to a plane capacitor, it can be twice with a 100 wt% of CNTs content. But, the impregnation of the insulating material in the surface roughness remains the key point of the realization of the hybrid capacitor. The roughness accessibility is a major property to optimize in order to improve the impregnation of the insulating material to increase the electrical capacitance

A Rare Case of Immature Ovarian Teratoma with Gliomatosis Peritonei

Gliomatosis peritonei (GP) is a rare condition that occurs almost exclusively in the setting of ovarian immature teratoma. It is characterisized by the occurrence of nodules of mature glial tissues in the peritoneum, omentum and bowel wall. The glial tissue in such cases is usually low grade although there have been cases of malignant evolution described. In general, the prognosis for GP is good. It depends chiefly on the degree of maturity of the implants. In mature GP, usually no additional chemotherapy is necessary. In immature GP, chemotherapy can induce maturation of the implants. We present a case of immature ovarian teratoma associated with low grade GP.Keywords: Glial tissue, gliomatosis peritonei, immature teratoma, India, ovar

Critical review on various types of Dadhi with reference to its method of preparation

Ayurved is the science for the preventive, promotive and curative aspects in health system. Dadhi is said as Dugdha Vikruti means milk product. Dadhi is one of the oldest Indian fermented milk products and may be considered the western equivalent to yoghurt. Acharya Sushruta has mentioned 7 categories of Dadhi (Curd). It is prepared by either method using acidic substances like lemon juice, vinegar or homemade by transferring a spoonful of the previous batch of Dadhi to Shrutaksheer (heated milk) at room temperature. It absorbs water from intestines hence also having properties as Grahi. By the virtue of this property, it is widely used to treat diarrhoea and dysentery. It causes heaviness when used in excess and may cause constipation. It mitigates Vatadosha, increases Kapha and Pitta. Consumption of curd accelerates digestion (Agni), stimulates taste buds and acts as an appetizer. Modern science has focused on preparation curd from milk. It is obtained by process of coagulation of milk (Curdling)

Pegasus Simulator: An Isaac Sim Framework for Multiple Aerial Vehicles Simulation

Developing and testing novel control and motion planning algorithms for aerial vehicles can be a challenging task, with the robotics community relying more than ever on 3D simulation technologies to evaluate the performance of new algorithms in a variety of conditions and environments. In this work, we introduce the Pegasus Simulator, a modular framework implemented as an NVIDIA Isaac Sim extension that enables real-time simulation of multiple multirotor vehicles in photo-realistic environments, while providing out-of-the-box integration with the widely adopted PX4-Autopilot and ROS2 through its modular implementation and intuitive graphical user interface. To demonstrate some of its capabilities, a nonlinear controller was implemented and simulation results for two drones performing aggressive flight maneuvers are presented. Code and documentation for this framework are also provided as supplementary material

Design of Microcantilever-Based Biosensor with Digital Feedback Control Circuit

This paper present the design of cantilever-based biosensors with new readout, which hold promises as fast and cheap “point of care” device as well as interesting research tools. The fabrication process and related issues of the cantilever based bio-sensor are discussed. Coventorware simulation is carried out to analyze the device behavior. A fully integrated control circuit has been designed to solve manufacturing challenge which will take care of positioning of the cantilever instead of creating nanometer gap between the electrodes. The control circuit will solve the manufacturing challenge faced by the readout methods where it is essential to maintain precise gap between the electrodes. The circuit can take care of variation obtained due to fabrication process and maintain the precise gap between the electrodes by electrostatic actuation. The control circuit consist of analog and digital modules. The reliability issues of the sensor are also discussed
