This paper compares the difference between boy and girl high school students of 1st grade to 3rd grade in academic stress and depression. Using a random stratified sampling 120 girl and boy students (60 girls and 60 boys) were selected from 1st grade (n=40), 2nd grade (n=40) and 3rd grade (n=40) high school students. In this study gender and grades have considered as independent variables and academic stress and depression were dependent variables. A scale for assessing academic stress (SAAS, Sinha, Sharma and Mahindra, 2001) and children depression inventory (CDI, Kovacs, 1992) were used for collecting data. To analyze of data statistics such as mean, SD, Pearson's coefficient of correlation and regression homogeneity to test of variance's homogeneity, and multivariate analyze of variance (MANOVA were used). Results showed that the effect of gender on combined dependent variables (academic stress and depression) was statistically significant (Wilk's Lambda=.367; F (12, 103) = 14.81, p=.000; Eta=.63); the effect of grade on combined dependent variables was statistically significant (Wilk's Lambda=. 708; F (24, 206) = 1.98, p=.05; Eta=.16); The mutual interaction of gender and grades on combined dependent variables was not significant (Wilk's Lambda=.774; F 24, 206= 1.71; p=.272; Eta= .12). The effect of gender on academic stress and its subscales (Wilk's Lambd=.648; F 6, 113=10.23; p<0.05; Eta=.35); and depression and its subscales (Wilk's Lambd=.495; F6, 113=19.22; p<0.05; Eta=.51) was statistically significant. Further the effect of grades on academic stress was significant but the effect of grade on depression was not significant. Finally the study concluded that there was a significant difference between boy and girl students in academic stress and depression.

The purpose of this study was to investigate the association between Emotion Regulation and quality of life. Five hundred and thirty-eight adults, 262 men and 276 women, selected through random sampling method participated in the study. Emotion Regulation Questionnaire (ERQ) and Quality of Life-BREF scale (WHOQOL-BREF) were used to gather data. Results of the study revealed a significant correlation between the variables; however, reappraisal showed a positive relationship with quality of life while suppression showed a negative relationship. There was no gender difference.

This paper investigates the relationship of academic stress with aggression, depression and academic performance of college students. Using a random sampling technique, 60 students consist of boys and girls were selected as students having academic stress. The scale for assessing academic stress (Sinha, Sharma and Mahendra, 2001); the Buss-Perry aggression questionnaire (1992); and Beck depression inventory were used for collecting the data. The Pearson's coefficient of correlation showed that academic stress has a simple significant correlation with aggression (r=.54), depression (r=.49) and academic performance (r=-44) (p<. /..1). Further, the analysis of the study shows that academic stress, aggression and depression are able to explain 68% of the variance of academic performance. Also, results show that boys and girls are different in terms of aggression and depression.

Syngas generated from the thermochemical conversion of biomass in a gasifier is increasingly being used for fuelling internal combustion engines, especially for distributed power generation. Producer gas as a fuel has thermo physical properties significantly different from those of conventional fuels. As of date, there are no dedicated engines for alternative fuels in general and producer gas in particular. A review of the available literature indicates experimental experience with producer gas but very little information on modelling and simulation studies are available. While experimental investigations provide actual performance parameters, the information is essentially spatial or temporal average only. Apart from that, fluid dynamic and combustion progress parameters cannot be acquired inexpensively. The current work primarily addresses the combustion progression parameters in a typical spark ignited engine under naturally aspirated and turbocharged after cooled configuration at varying mixture quality using the ANSYS FLUENT computational fluid dynamics software. The CHEMKIN software is used for determining the laminar flame speed for producer gas as a function of the mixture quality. Spatially averaged pressure traces from the simulation are compared with literature pressure traces at the desired condition and various simulation parameters are tuned till a match between the literature and simulation pressure is obtained. Once the simulation is validated, the progress of combustion parameters is derived from the simulation in post processing.
