Generally, socialization can be described as the process whereby a kid eventually becomes a more or less perfect member of a society in all respects and acquires the skills necessary to function amid the culture in which he/she is born and begins to grow. For a child, the drivers or the factors behind his/her behaviour include his/her own family and the members who interact with him/her. This socialization process leads to many merits and demerits in a child's life. One of the most serious demerits is the consumption pattern of the child which is influenced by his/her surrounding environment. The world today is witnessing childhood obesity rate, which is rising every year at an alarming pace. The habit of eating junk food (which is one large source of fat which accumulates in the body) has increased over the years, also contributing to the obesity issue. This study, conducted during 2011 to 2013, attempted to find out the reasons that could be attributed to the increasing level of childhood obesity in the cities of Chennai and Hyderabad, and the role of persuasive marketing in aggravating the issue. This article defined those reasons as motivational perception factors, that is to say, the elements which motivate the children to consume certain things about which they have their own perceptions.

The biological quality of secondary treated sewage effluent was evaluated using a toolbox approach, which combined a larval developmental bioassay and measurement of fecal indicator organisms. The zoea developmental toxicity of Scylla serrata from stage I to stage II was determined by exposing to a range of secondary treated sewage concentrations. Results indicated that the relative progress of zoea stage I to zoea stage II negatively correlated with increasing sewage concentrations. Data was analyzed statistically to determine lethal, median lethal, sublethal, low observed effect, and no observed effect concentrations. Water samples collected along the Buckingham canal discharge zone were also analyzed for its toxicity to the larval development. Fecal indicator organisms chosen to determine the water quality were E. coli, enterococci, C. perfrigens, and F+ coliphages. Concentrations of these fecal markers were determined in the raw influent, primary treated effluent, secondary treated effluent, and in four discharge zone sites. Data showed that this biological toolbox is helpful for providing baseline information on the effectiveness of the wastewater treatment and environmental health of the discharge zone. © 2017 Springer-Verlag Berlin Heidelberg

This paper investigates the influence of price responsive demand shifting bidding on congestion and locational marginal prices in pool-based day-ahead electricity markets. The market dispatch problem of the pool-based day-ahead electricity market is formulated as to maximize the social welfare of market participants subject to operational constraints given by real and reactive power balance equations, and security constraints in the form of apparent power flow limits over the congested lines. The social welfare objective function of the day-ahead market dispatch problem maximizes the benefit of distribution companies and other bulk consumers based on their price responsive demand shifting bids and minimizes the real and reactive power generation cost of generation companies. The price responsive demand shifting bidding mechanism, which has been recently introduced in the literature, is able to shift the price responsive demand from the periods of high price to the periods of low price in day-ahead electricity markets. The comparisons of the price responsive demand shifting bids with conventional price responsive and price taking bids are presented by solving hourly market dispatch problems on five-bus, IEEE 30-bus, realistic UP 75-bus Indian, and IEEE 118-bus systems for 24-h scheduling period. It has been demonstrated that the proposed approach leads to reduction in congestion and locational marginal prices as compared to price responsive and price taking bids and meets the energy consumption targets of distribution companies/bulk consumers. © 2010 IEEE.

Purpose: This paper seeks to review the industrial applications of state-of-the-art additive manufacturing (AM) techniques in metal casting technology. An extensive survey of concepts, techniques, approaches and suitability of various commercialised rapid casting (RC) solutions with traditional casting methods is presented. Design/methodology/approach: The tooling required for producing metal casting such as fabrication of patterns, cores and moulds with RC directly by using different approaches are presented and evaluated. Relevant case studies and examples explaining the suitability and problems of using RC solutions by various manufacturers and researchers are also presented. Findings: Latest research to optimize the current RC solutions, and new inventions in processing techniques and materials in RC performed by researchers worldwide are also discussed. The discussion regarding the benefits of RC solutions to foundrymen, and challenges to produce accurate and cost-effective RC amongst AM manufacturers concludes this paper. Research limitations/implications: The research related to this survey is limited to the applicability of RC solutions to sand casting and investment casting processes. There is practically no implication in industrial application of RC technology. Originality/value: This review presents the information regarding potential AM application - RC, which facilitates the fabrication of patterns, cores and moulds directly using the computer-aided design data. The information available in this paper serves the purpose of researchers and academicians to explore the new options in the field of RC and especially users, manufacturers and service industries to produce casting in relatively much shorter time and at low cost and even to cast complex design components which otherwise was impossible by using traditional casting processes and CNC technology. © Emerald Group Publishing Limited.

The purpose of the present investigations is to study the effect of moulding sand on decreasing shell wall thickness of mould cavities for economical and statistically controlled hybrid rapid casting solutions (combination of three dimensional printing and conventional sand casting) for zinc alloys. Starting from the identification of component/ benchmark, technological prototypes were produced at different shell wall thicknesses supported by three different types of sands (namely: dry, green and molasses). Prototypes prepared by the proposed process are for assembly check purpose and not for functional validation of the parts. The study suggested that a shell wall with a less than recommended thickness (12mm) is more suitable for dimensional accuracy. The best dimensional accuracy was obtained at 3mm shell wall thickness with green sand. The process was found to be under statistical control. © 2010 The Korean Society of Mechanical Engineers and Springer-Verlag Berlin Heidelberg.

The purpose of the present investigation is to study the effect of molding sand properties on investment casting (IC) for process capability analysis. Starting from the identification of component/benchmark, ICs were produced with different grades of silica slurry layers (coarse, medium and fine) over the patterns (in the form of a tree). Measurements on a coordinate measuring machine (CMM) helped in calculating the dimensional tolerances of the castings produced. Some important mechanical properties were also compared to verify the suitability of the castings. The study suggested the long-term performance level of the IC process after it has been brought under statistical control as casting solution for plain carbon steel. The provided data from the experimentation highlights the ability of the IC process to produce a product that will consistently meet the design requirements and the customer expectation. © 2013 The Korean Society of Mechanical Engineers and Springer-Verlag Berlin Heidelberg.

The paper presents the results of laboratory model tests on bearing capacity behaviour of a strip footing resting on the top of a geogrid reinforced flyash slope. A series of model footing tests covering a wide range of boundary conditions, including unreinforced cases were conducted by varying parameters such as location and depth of embedment of single geogrid layer, number of geogrid layers, location of footing relative to the slope crest, slope angles and width of footing. The results of the investigation indicate that both the pressure-settlement behaviour and the ultimate bearing capacity of footing resting on the top of a flyash slope can be enhanced by the presence of reinforcing layers. However the efficiency of flyash geogrid system increases with the increasing number of geogrid layers and edge distance of footing from the slope. Based on experimental results critical values of geogrid parameters for maximum reinforcing effects are established. Experimental results obtained from a series of model tests have been presented and discussed in the paper. © 2009 Elsevier Ltd.
