In the paper we extend some Hardy and Littlewood type inequalities on time scales for the function of n variables. Special cases of obtained results include generalized Wirtinger, Hardy and Littlewood type inequalities.

Series of Cobalt nanoparticles incorporated polymethylmethacrylate composites in the presence and absence of dodecyl-benzenesulphonic acid (DBSA-CoNPs/PMMA and CoNPs/PMMA, resp.) were synthesized by solution mixing methodology. UV-visible and FTIR techniques were used to confirm the formation of nanocomposite. UV-visible spectra of the composites showed the incorporation of filler particles in the polymer matrix. On the other hand, FTIR spectra indicated the physical interaction between the two phases of the composite. Moreover, the electrical nature of the composites was studied by plotting graphs between electrical conductivity (measured using LCR meter at 100 kHz) and contents of the filler particles as introduced in the polymer matrix. An increase in electrical conductivity was first observed with increasing filler concentration up to the critical percolation threshold value (0.5% for DBSA-CoNPs/PMMA and 1% for CoNPs/PMMA), which then dropped upon further increments in the filler content. However, at higher concentrations, a second jump in the conductivity was observed in case of DBSA-CoNPs/PMMA composites.

Increasing awareness on the various environmental problems has led a shift in the way consumers go about their life. There has been a change in consumer attitudes towards a green lifestyle and people are actively trying to reduce their impact on the environment. Massive industrialization has changed this world radically and leaving behind a curse to nature. Environmental reduction is a concern of people all around the globe. The purpose of this study is to identify the important factors that influence the green purchase intentions of the people. This study investigates the effects of different variables on green purchase intention of consumers. A sample of 150 respondents was taken from the students and professional in Bahawalpur City of Pakistan. The data was collected through a self-administered questionnaire, using the previous established scales. Regression results of the study validate all the hypotheses of the study confirming the significant impact of green perceived value, green trust, green environmental responsibility, green marketing tools and green purchase attitude on green purchase intention. The current study falsifies the assumption that the consumers in developing countries are less prone towards purchasing of green products. Managerial implications and limitations are discussed to make this study more fruitful.
