The society and culture of Bangladesh are quite different from the other countries of the world. It is difficult to receive a theory fully for explaining the condition of our own. However, the purpose of this paper is to review major sociological theories on aging and propose a new one. Data were collected from both primary and secondary sources. Content analysis and survey methods were used in this study. Through the baseline survey of four villages in the Bogra District of Bangladesh, 609 older people have been identified. Among them, 203 older people including 96 males and 107 females have been selected as a sample randomly and interviewed intensively. The contents of aging-related theories have been analyzed. The results of this study show that existing theories of aging are inadequate to explain the social aspects of older adults in Bangladesh;rather Ignored Engagement (A Piloted Theory) may be suitable to do this. This study may give future direction to academicians and policymakers to formulate and amend evidence-based policies and practices for the well-being of our older people.

The heat and mass transfer of unsteady MHD two-dimensional mixed convection boundary layer flow over an exponentially porous stretching sheet is presented in this paper. Multiple slip conditions, radiation, suction or blowing, heat generation or absorption along with magnetism and porous medium are incorporated. We reduce the leading equations which are partial differential equations into a family of ordinary differential equations that are non-linear using a set of similarity transformations. The resulting equations with coupled boundary conditions are solved numerically with the aid of bvp4c solver with MATLAB package. The impacts of several non-dimensional governing parameters on the flow fields such as velocity, temperature and concentration profiles along with friction coefficient, temperature gradient and concentration gradient are portrayed graphically and discussed in detail. The result indicates that the magnetic parameter decreases the skin friction coefficient. Thermal boundary layer thickness reduces with increasing radiation parameters and enhances with increasing Prandtl number. It is also observed that the thermal slip parameter depreciates the heat transfer rate and the mass slip parameter diminishes the mass transfer rate. A comparison has been made between the current results and the numerical results of previous studies and observed a very close good agreement.

Along with conventional methods, this paper proposed a method in which 1 D and 3 D models are integrated to identify the self-sourced reservoir potential of the Farewell Formation in the Kupe Gas Field within the Taranaki Basin, New Zealand. Source rock characteristics were evaluated at both field and basin scales by investigating source rock maturity, type of organic matter,and hydrocarbon generation potential by rock pyrolysis,using Rock-Eval 2 and 6. The 1 D thermal and burial history model established the rate of sedimentation and thermal history of the Kupe 4 well. Reservoir characterization at field-scale was determined by seismic interpretation, well log analysis, and 3 D structural and petrophysical models. The sediments of the Farewell Formation contain types II-III（oil/gas prone） and type III（gas prone） and have fair-to-excellent generation potential. The oxygen and hydrogen indices ranged from 3 to 476 mg CO2/g TOC and 26 to 356 mg HC/g TOC, respectively, whereas the thermal maturity determined by vitrinite reflectance values ranged between 0.3% and 0.72%, indicating that the Farewell Formation is in immature-to-mature hydrocarbon generation stage. Thus, Farewell Formation was verified to be a good source rock. Additionally, structural interpretations demonstrated the structural complexity of an extensional and contractional regime within the reservoir package. Multiple faults indicated a good reservoir property there with a trapping mechanism as well as migration paths. A well-log-based petrophysical analysis established the presence of up to 70% hydrocarbon saturation within the pore spaces of Farewell *** 3 D models confirmed that the Farewell Formation has significant sand zones and hydrocarbon-saturated zones,thereby proving its very good reservoir characteristics. It has been proved that the 1 D and 3 D structural schemes,integrated with geological techniques, was vital in identifying the Kupe Field as a self-sourced reservoir.

Using C_(4)-C_(25)fatty acid methyl esters(C_(4)-C_(25)FAMEs)as a sample reference series,a method was developed to generalize the reference system for calculating the second dimension retention index(2I)of compounds analyzed by comprehensive two-dimensional gas chromatography-mass spectrometry(GC×GC-MS).The second dimension elution temperature(2Te),second dimension unadjusted retention time(2tR),and the linear retention index(IT)of C_(4)-C_(25)FAMEs were used to form a second dimension retention index surface(2IS)via a three-dimensional surface fitting *** 2I of an analyte analyzed by GC×GC-MS was then calculated from the 2IS based on its 2tR and *** developed method was validated by calculat-ing the 2I of n-alkanes,80 compounds,and two commercially available mixtures(MegaMix A and MegaMix B).Compared to the conventional method,the developed method keeps the 2I in n-alkane retention index scale,and enables using any compounds as references to obtain a much increased separation space in the second dimension GC.
