Understanding the burden and pattern of mental disorders as well as mapping the existing resources for delivery of mental health services in India, has been a felt need over decades. Recognizing this ...necessity, the Ministry of Health and Family Welfare, Government of India, commissioned the National Mental Health Survey (NMHS) in the year 2014-15. The NMHS aimed to estimate the prevalence and burden of mental health disorders in India and identify current treatment gaps, existing patterns of health-care seeking, service utilization patterns, along with an understanding of the impact and disability due to these disorders. This paper describes the design, steps and the methodology adopted for phase 1 of the NMHS conducted in India. The NMHS phase 1 covered a representative population of 39,532 from 12 states across 6 regions of India, namely, the states of Punjab and Uttar Pradesh (North); Tamil Nadu and Kerala (South); Jharkhand and West Bengal (East); Rajasthan and Gujarat (West); Madhya Pradesh and Chhattisgarh (Central) and Assam and Manipur (North East). The NMHS of India (2015-16) is a unique representative survey which adopted a uniform and standardized methodology which sought to overcome limitations of previous surveys. It employed a multi-stage, stratified, random cluster sampling technique, with random selection of clusters based on Probability Proportionate to Size. It was expected that the findings from the NMHS 2015-16 would reveal the burden of mental disorders, the magnitude of the treatment gap, existing challenges and prevailing barriers in the mental-health delivery systems in the country at a single point in time. It is hoped that the results of NMHS will provide the evidence to strengthen and implement mental health policies and programs in the near future and provide the rationale to enhance investment in mental health care in India. It is also hoped that the NMHS will provide a framework for conducting similar population based surveys on mental health and other public health problems in low and middle-income countries.

Dry sliding friction and wear behavior, hardness, and thermogravimetric analysis (TGA) of Cissus quadrangularis stem fiber (CQSF)/epoxy resin composite, reinforced with red mud particulate filler ...were done. The hardness of the material increased by adding red mud filler. Thermogravimetric analysis (TGA) reveals that the maximum char yield obtained at 10 wt.% red mud particulate-filled with CQSF/epoxy composite. The optimization of dry sliding friction and wear behavior was done by response surface methodology (RSM) based on pin-on-disc wear test to determine the specific wear rate (SWR) and coefficient of friction (COF) of the materials. The experimental design was created with four input parameters at three different levels using full factorial central composite design (CCD). The minimum SWR was achieved at 5.93 wt.% red mud addition irrespective of other parameters, was obtained by RSM optimization technique. The scanning electron microscopy (SEM) images of the worn out surfaces substantiate the optimized results of wear properties.

In the era of stiff competition and customer expectations, manufacturing organizations across the world are struggling hard to minimize their costs and maximise their performance. Micro, Small and ...Medium enterprises (MSMEs), who are dependent on large corporate for business and support have a tall task of keeping pace quality in processes and output. They are in the constant vigil to adopt new systems and practices so that they can minimise their cost and maximize the productivity. This study has been conducted in the machine tool sector of Coimbatore, India; which houses more than 9000 companies and offers employment to over one lakh employees. They have a tremendous pressure to use scientific processes to increase their product quality and productivity. While Lean manufacturing has been the thrust to improve the competitiveness among MSMEs in India, this study has attempted to understand their attitude towards lean management and understand the extent to which companies practice lean tools and practices. It has been found that most of the organizations in the study possess a culture of lean thinking and possess the support of top management and employees also towards the initiative. It is also seen that the organizations that incorporated lean in their daily operations have been able to scale up their productivity.
In the current globalized scenario, business organizations are more dependent on cost effective supply chain to enhance profitability and better handle competition. Demand uncertainty is an important ...factor in success or failure of a supply chain. An efficient supply chain limits the stock held at all echelons to the extent of avoiding a stock-out situation. In this paper, a three echelon supply chain model consisting of supplier, manufacturing plant and market is developed and the same is optimized using particle swarm intelligence algorithm.

Bumper is one of the essential parts in an automobile. During collision, bumper is used as a protection shield to safeguard passengers and the body of the vehicle. We know that, death in accident is ...very common not only in India but also all over the world. Therefore, safety of passengers and automobile body must be considered as primary criteria at the time of vehicle design. ABS is a material which has high impact strength which is used for manufacturing automobile bumper. In this research, we endeavour to analyse three different front bumpers of expensive cars which are highly competitive in the automobile market. CATIA V5R21 is the software used for modelling the bumpers and ANSYS 19.2 is used for analysing each bumper with appropriate velocities. In this research, thickness of all the bumpers is considered as 5 mm and the concrete wall where it is collided to make impact collision is of thickness 10 mm. By using explicit dynamic condition with exact boundary conditions, we determine the best or optimistic design by comparing the results of various factors such as equivalent stress, total deformation, directional deformation and equivalent plastic strain.
Due to large scale industrialisation and indiscriminate discharge of effluents with high BOD, sulphuric acid, oil, toxic metals and particulate matter reach the aquatic environment, either directly ...or indirectly. Living organisms consist less than one percent of heavy metals, and their different density cause to some disorders. Surface waters and also acidic rains can transfer these metals to oceans via washing polluted environment. Heavy metals naturally exist in very little amount in watery places. Metal pollution of the sea is less than other types of water pollution but its effects on marine ecosystems and humans are very extensive. Industrial wastes in aquaculture because toxic effects in aquatic organisms especially in fishes. Aquatic organisms absorb the pollutants directly from water and indirectly from food chains. Some of the toxic effects of heavy metals on fishes and aquatic invertebrates are; reduction of the developmental growth, increase of developmental anomalies, reduction of fishes survival- especially at the beginning of exogenous feeding or even cause extinction of entire fishes population in polluted reservoirs. The objective of this project is to investigate the heavy metals in industrial effluents and reducing it by using Nano Adsorbent of Vetiveriazizanioides. This method is more efficient than any other method for reducing heavy metals from industrial effluents, because it is biodegradable. The results obtained from this attempt shows that heavy metals reduction by this Nano adsorbent is in the range of decreases like Hg > As > Cd > Pb.

A modal shift occurs when one mode of transport has a comparative advantage in a
similar market
over another. The present work concerns with the development of
modal shift model
for urban travel in ...Chennai, India. The modal shift model was calibrated using binary logit technique and validated using hold-out sample method. The validated model was used to predict the probability of shift in selected corridor. The recent introduction of metro rail in Chennai has lead to an increasing competition among public transport modes. To study the influence of metro on bus transport, a Stated Preference (SP) survey was conducted among express bus travellers. Using the SP survey data, a modal shift model was calibrated to estimate the plausible shift from bus to metro. Results indicate that variables like
fare
-
difference
,
age, and income
play an important role in the shift behaviour. When metro fare increases with respect to express bus fare, bus passengers are less willing to use metro and vice-versa.
