The failure rate curve is identical for all mechanical systems. The Aero-engines are not exception to that. Theoretically they may have identical curves for failure rate. But there are many factors, like variation during manufacturing, assembly, operations and maintenance that affect the failure rate and frequency of failures for aero-engines. Even if the engines are operated and maintained by same operator, their failure patterns will be differing from engine to engine. This paper considers all such potential factors that lead to variations in performance and prediction of residual life for engines. This paper proposes a method to minimize the percentage of errors in prediction of reliability and mean residual life. © Research India Publications.

Menopause is the term used to describe the permanent cessation of ovarian function in women. It marks the transition of women from fertile phase to non-fertile phase. The typical age for onset of menopause in women normally is between late 40s and early 50s but in many cases it may vary. Menopause is due to hormonal imbalance occurring in women during the menopause period. The hormone estrogen responsible for ovulation will gradually decrease in the body. Estrogen acts through many different mechanisms to help keep the blood vessels flexible and to modulate other hormone activities that can contribute to developing high blood pressure. This is the reason behind the absence of cardiac arrest in women before menopause. Blood pressure of a menopause woman is known to be high. The work has been designed to measure the clinical parameters like blood pressure, weight, BMI, pulse rate, heart beat rate, blood sugar level in different age group of menopause women. From the results it is evident that BMI gradual increase according to the menopause age of the women.whereas heart rate and blood pressure showed insignificant increase from 4 th year of menopause period whereas remarkable increase was observed in all parameters from 8 years of menopause period.

Fiber-reinforced polymer composites have played a dominant role for a long time in a variety of applications for their high specific strength and modulus. The fiber which serves as a reinforcement in reinforced plastics may be synthetic or natural. Past studies show that only synthetic fibers such as glass, carbon etc., have been used in fiber-reinforced plastics. Although glass and other synthetic fiber-reinforced plastics possess high specific strength, their fields of application are very limited because of their inherent higher cost of production. In this connection, an investigation has been carried out to make use of coir, a natural fiber abundantly available in India. Natural fibers are not only strong and lightweight but also relatively very cheap. The present work describes the development and characterization of a new set of natural fiber based polymer composites consisting of coconut coir as reinforcement and polymer as resin. The newly developed composites are material for many structural and non-structural applications. This work can be further extended to study other aspects of such composites like effect of fiber content, fiber characterized with respect to their mechanical characteristics. In the present work, coir composites are developed and mechanical properties are studied. These results indicate that coir can be used as a potential reinforcing orientation, loading pattern, fiber treatment on mechanical behavior of coconut coir based polymer composites. © Research India Publications.

An investigation has been made to reduce the effect of curing time of phenol formaldehyde resin by incorporating latent acid catalyst at various percentages. The latent acid catalyst is used because of its capability to form more methylene bridge with phenol formaldehyde enabling fast curing at reduced temperatures and time. The curing of phenol formaldehyde takes place at higher temperature of about 110-140°C. Various latent acid catalysts are experimented and para-toluene sulphonic acid which is blocked by isopropanol is found best to serve as a latent acid catalyst. The characterisation techniques such as Fourier transform infrared spectroscopy, Differential Scanning Calorimetry and Thermogravimetric analysis were carried out. The latent acid catalyst of 40% para-toluene sulphonic acid and 60% isopropanol has been found. The amount of catalyst required to reduce curing time is determined to be 7 min 52 sec. It is observed that gel time (or) cure time of the phenol formaldehyde resin decreases with increasing catalyst content. © 2016, Sphinx Knowledge House. All rights reserved.

The water and the sediment were collected from different fish farms. The organism should be isolated from the samples and that organism should be protease producing. The protease is the enzyme that breaks down the protein molecules. The protease producing organism is that the microorganism which can able to break down the protein molecule. Eg: Bacillus spp, Aeromonas hydrophila, Aeromonas sobria. This bacteria were grown on the milk agar media. The colonies that are having the zones around it are separated and subcultured in the nutrient agar plates. Then the gram staining can be done for the identification of morphological characteristic of the bacteria. The organism can be subcultured in the LB broth. The DNA is then isolated from the organism and that isolated DNA is used for the RAPD analysis using the primers OPA-13,OPU-18,OPA-20. The samples were run in the agarose gel and the amplified DNA bands are observed. The genetic variability between the closely related organism can be studied by using this RAPD technique. © 2014, Sphinx Knowledge House. All rights reserved.

Rice husk (RH) is an agricultural waste, which is easily available in the market and Silica (SiO2) is the most abundant material in the earth’s crust. This paper addresses the production of silica from the rice husk. The Rice husk ash (RHA) is obtained by burning of rice husk in a muffle furnace at a temperature of 500, 600 and 7000C, which is bio-organic Silica (SiO2) and has high pozzolanic activity. The temperature and the time duration for the combustion process are optimized. X-ray Fluorescence (XRF) analysis is carried out to determine the chemical composition of rice husk and that of the rice husk ash. The formed rice husk ash is treated with Sodium hydroxide (NaOH) and Hydrochloric acid (HCl) to produce silica. The obtained silica is used for the various applications like automotive industry, cosmetic industry, etc. The compound of silica like Sodium silicate (NaSiO3) is used for water treatment, concrete treatment, cement production, etc. The brief explanation for the process is given below. © 2014, Sphinx Knowledge House.

Failure/problem is defined as a deviation from standard/desired performance. It is an undesired result of a job. It can also be stated as the gap between target and current level. Traditional mind set about Problem/ Failures is Shame, Humiliation, Disgrace, Dishonour, Faults, Weak Points, Flaws etc. Naturally people look to cover up or hide their problems. But the ideal view is exactly the opposite. It tells that Problems = Mountains of treasure. Our problems show us how much room for improvement we have. © 2014, Sphinx Knowledge House.

The present study is performed to screen the daily blood pressure changes in the entire cycle of menstrual cycles. As we are aware that many hormones involved in regulating the menstrual cycle which has its influence on the blood pressure directly or indirectly. India is a highly populated country hence Government of India and State Government of Tamilnadu has taken various measures to control the population through various family planning programmes. Presently the effective family planning method is by using oral contraceptives which contain synthetically prepared hormones. These hormones although it controls conception, since it contains synthetic which show toxic signs by altering the physiology which may results in psychopharmacological by altering the metabolic functions. If these toxic signs are neglected for a long time leads to cancer. In this study 10 female subjects having normal menstrual cycle with the age group of 15 - 20 years were selected since the cycle will be very effective in these age group girls. In this study we observed a study increase in blood pressure in luteal phase when compared to other follicular or menstrual flow period. Regarding the other three phases of the cycle, they show fluctuating results which may be due to the living environment and hormones. During these three phases when we compare the blood pressure of morning and evening it shows high fluctuation which is not observed in the luteal phase where it shows a steep increase in the entire day. Similar studies will help us to identify the time of increase in the entire luteal period of the menstrual cycle. © 2010 RJPBCS.
