Investigation of the Effects of Inlet System Configuration on the Airflow Characteristics

The effort towards the development of an engine that is efficient and green has become one of the biggest efforts of the major part of the automotive industry. The contribution of air quality to the engine plays an important role to increase power while minimizing the exhaust emission. The main purpose of this article is to investigate the characteristic of the air intake system of a naturally aspirated engine on a steady flow bench. The experiment was conducted using an industrial flow bench apparatus where the pressure different test pressures can be set and, at every test pressure, the valve is lifted at an increment of 1mm until the maximum possible valve lift where the flow rate is obtained in terms of cubic foot per minute or CFM. The experiment process was then repeated at different configuration. The experimental result shows that the flow rate increases with each valve lift in a linear pattern until at a certain point where the value becomes constant. The result also indicated that the flow rate increases as the different pressure increases

2-{(E)-[(2Z)-(3-Chloro-1-methyl-2,2-di­oxo-3,4-dihydro-1H-2,1-benzo­thia­zin-4-yl­idene)hydrazinyl­idene]meth­yl}phenol

In the title compound, C16H14ClN3O3S, the thia­zine ring adopts a sofa (half-chair) conformation, with an r.m.s. deviation from the mean plane of 0.23 Å. The S atom and S-bonded C atom exhibit the maximum deviations from the thia­zine mean plane [−0.3976 (12) and 0.3179 (14) Å, respectively]. The conformations around the double bonds in the R 2C=N—N=CHR unit are Z and E. An intra­molecular O—H⋯N hydrogen bond with the hy­droxy group as donor generates an S(6) ring motif. In the crystal, pairs of weak C—H⋯O inter­actions connect the mol­ecules, forming inversion dimers

Residents’ perception of community based sport tourism related activities in Sarawak

This study investigates host community perceptions and expectations towards the impact of community based sport tourism related activities in Kapit-Baleh, Sarawak and how it affects the host residents’ daily livelihood in the tourism destinations. The sample populations consisting of longhouse residents, participants, tour operators and local council officer who are directly involved in the activities. This study integrates social exchange theory and as the framework for investigating the individual and societal components of perceptions of sport tourism in residents’ attitudes. Community based sport tourism event impact assessment (COMSTEIA) was established as a guidelines process for this study to assess the level of expectation and perception of the local host community. The research was conducted by using qualitative and quantitative perspectives. Throughout the study, data is collected by using different methods which reflects that triangulation was largely utilized in the research. Three hundred and eighty respondents completed the survey Factor analysis is use to identify the underlying dimension and variables. Accordingly, the study proposes three research questions: (1) level of perception (2) level of perceived expectation and (3) importance of the activities. The findings of this study indicate that the range of level of expectation and perception varied from different dimension. There seem to be enough related evident at this point to conclude there is an association between support for tourism to cultural and economic development and perceptions of its positive impacts on the local community. These findings are consistent with the social exchange theory to those who view these activities as a catalyst for development. The host community have positive perception towards economic benefits before the activities but at the end of the activities the host community give negative perceptions based on the benefit from the activities as further explained in the Social Exchange Theory. It has been established that host community from different longhouse might perceive the activities as unacceptable, while in other longhouse, the activities maybe more acceptable. Further research opportunities are presented by these conclusions and may be further explored. There is a need to formulate strategies, processes and frameworks to engage and empower host community involve in community based sport tourism related activities. The result of this study provides a platform for local authority to reflect upon and revise their modes of governance for community based sport tourism related activities

Green and sustainable construction practices impact on Organizational Development

Green Marketing plays important role in the organizational performance irrespective to the industry and the type of project. However green construction research lacks in the field of a construction project. The basic purpose of this work was to highlight the impact of modern techniques such as green construction on organizational performance through the adoption of sustainable practices in business strategies in the construction industry. Data were collected from 132 organizations, working on different construction projects located within the city of Rawalpindi and Islamabad, through an online questionnaire survey in two strata in terms of consultant and contractors. Data were analyzed through different tests, included Pearson’s correlation coefficient as well as regression using IBM SPSS Statistics Version 20. The study indicated that green construction has a strong correlation and positive impact on organizational performance, and this correlation partially mediated by sustainable development. The research findings have practical implications both in organizational and project manager’s perspectives. This research was limited to a specific geographic area due to time and cost constraints. Future researchers may opt to conduct the study in other geographic areas of Pakistan and in different industries. Moreover, additional or different mediating variables can also be used in future work

Beliefs about Islamic advertising: an exploratory study in Malaysia

Purpose – This paper aims to explore people’s beliefs towards Islamic advertising. Design/methodology/approach – Being exploratory in nature, this paper applies qualitative method of research by adapting thought elicitation technique of data collection. This method rests in the projective techniques of data collection and is also known as “word association technique”. It allows free thinking of respondents that helps in generating rich data which is most required in qualitative studies. Findings – Various beliefs regarding Islamic advertising were extracted and categorized into different dimensions. These dimensions pertained to Islamic advertising’s possibility, nature, characteristics, real-time decisions and potential outcomes. Research limitations/implications – Being an exploratory study, the data are collected from a small sample, hence raising generalization issues. Though, the same opens avenue for future research in that these dimensions should be subject to validation via large sample size. Practical implications – This research will help in developing a scale to measure attitudes towards Islamic advertising, which the researchers can use to find justification for using Islamic advertising. Such application has great implications for businesses, as Islamic advertising concept stands contrary to the contemporary practices. Social implications – With a growing concern for business ethics, this research is an attempt to bring Islamic ethics into advertising practice. This will not only eradicate the ill-effects of contemporary advertising but also provide sound evidence for revising advertising policies. Originality/value – It adds to the developing field of Islamic marketing, by being the first attempt of its kind in paving the way for Islamic advertising
