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.

This study explores the fabrication of Fe-based amorphous/crystalline coating by air plasma spraying and its dependency on the coating parameters(plasma power,primary gas flow rate,powder feed rate,and stand-off distance).X-ray diffraction of the coatings deposited at optimized spray parameters showed the presence of amorphous/crystalline *** deposited at a lower plasma power and highest gas flow rate exhibited better density,hardness,and wear *** coatings demonstrated equally good resistance against the corrosive environment(3.5wt%NaCl solution).Mechanical,wear,and tribological studies indicated that a single process parameter optimization cannot provide good coating performance;instead,all process parameters have a unique role in defining better properties for the coating by con-trolling the in-flight particle temperature and velocity profile,followed by the cooling pattern of molten droplet before impingement on the substrate.

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.

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.

利用三维地震和测井资料对Maui气田晚白垩世—上新世的沉积层序建立构造模型，结合地质统计学方法预测Taranaki盆地的构造力学特征。通过构造模型识别出受断裂影响的3期构造运动：晚白垩世—古新世裂谷期、晚始新世—中新世挤压性断裂期、上新世一更新世构造分化期（Maui气田南部挤压性断裂、Maui气田北部正断层活动）。各期构造运动形成不同的构造样式，早渐新世以前具有轻微走滑特征的正断层较发育，断层倾角大（40°-70°），北部地层倾角（10°-15°）低于南部（15°-20°）；中渐新世一晚中新世发育低角度逆断层（20°-40°），表明这一时期构造整体受到挤压性应力作用；中渐新世—上新世地层出现构造反转，表明这一时期构造应力为先挤压后拉张。
