Pressure vessel is a closed cylindrical vessel for storing gaseous, liquids or solid products. The stored medium is at a particular pressure and temperature. The cylindrical vessel is closed at both ends by means of dished head, which may be hemispherical, ellipsoidal. The pressure vessels may be horizontal or vertical. The supporting system of this vertical vessel plays an important role in the performance of the equipment. Proper supporting system gives better efficiency. The bottom supports are critical components since they are to be designed with much care to avoid failure due to internal pressure with temperature. In this analysis, skirt support for vertical vessel was analyzed as per the guidelines given in the ASME (American Society of Mechanical Engineering) section VIII division 2 and IBR (Indian Boiler Regulations) standards. The stress analysis was carried out for this support using a general purpose FEM code, ANSYS macros. The coupled field (Structural and Thermal) Analysis was carried out for skirt support to find out the stresses in the support. The analysis’s results were compared with ASME code allowable stress values.

Low cycle fatigue tests on as‐cast Sn–Ag eutectic solder (96.5Sn–3.5Ag) were carried out using a non‐contact strain controlled system at 20°C with different frequencies (10⁻³–1 Hz). Steps at the boundaries of Sn‐dendrites were found to be the initiation sites for microcracks in the case of low frequency fatigue tests, while for high frequency tests, cracks predominantly initiated at the boundaries of subgrains formed within Sn‐dendrites. The link up of these cracks and the propagation of cracks inside the specimen occurred both transgranularly through Sn–Ag eutectic phases, and intergranularly along Sn‐dendrite boundaries and/or subgrain boundaries. Propagation of stage II cracks for various frequencies could be characterized by the C*‐parameter.

Inconel 718 is used in gas turbine engines for aerospace applications due to high creep resistance but generating a hole with good surface integrity is challenging because the γ′′ interface is very strong so that slip is difficult in the grain boundary. So, the purpose of this work is to enhance the performance of drilling using a micro texture drill tool filled with solid lubricant.

Three different micro textures such as star shaped with 6-sharp apex, rectangular slots parallel and perpendicular to drill axis are created using laser on the drill tool. Deep cryogenic treatment is done on the textured tool to improve the strength and wear resistance before it is filled with solid lubricant. A detailed experimental investigation is performed to analyse the hole geometry and surface integrity of the drilled hole.

The accuracy of the drilled holes is enhanced in the star shaped texture drill tool over other textured and non-textured tools. A significant improvement in surface finish and hardness are observed and moreover cylindricity error, burr height of the hole is less for the above condition. It is also inferred that, at lower feed rate and higher speed produce hole with an accuracy of 96%.

Aerospace industry is focussing on improving the hole geometry and surface in Inconel 718. This work demonstrates the novel technique to improve drilling of Inconel 718 using laser textured tool filled by the solid lubricant.

Purpose – The main objective of this research is to explore the impacts of globalization on gender empowerment.

Methodology – This research uses a design that combines lagged cross-sectional and cross-sectional analyses. We have used ordinary least square regression. The sample size for this research is 48–70 nation-states. We have used gender empowerment measurement as an indicator of decision-making power that women in a society gain in decision making as a group.

Findings – Our findings illustrate variable effects of global economy on gender empowerment. Higher commodity concentration significantly lowers women's access to the formal and informal labor force and women's decision-making power after controlling for economic development, culture, and state's location in the global economy. Foreign direct investment lowers women's share in both the formal and informal labor force and women's decision-making power, while increasing women's share of secondary education. Thus, this research examines wider dimensions of women's experiences. We also find that some policies have positive effects, whereas others have negative effects on gender empowerment.

Originality/value of the chapter – Previous research on globalization and development has discussed the impacts of globalization on women's empowerment. However, researchers have either used women's access to formal work or education or gender development scores as an indicator of women's empowerment. Researchers have not captured women's empowerment completely. We have overcome this limitation by defining empowerment as a complex of access to resources (access to education, formal and informal labor force) and decision-making power (gender empowerment scores).

The present paper examines the barriers hindering the implementation of circular economy practices in Indian automotive industries and identifies the most critical barriers to be eradicated during the circular economy implementation.

Using a questionnaire survey-based analytic hierarchy process (AHP) approach, 21 barriers to circular economy implementation are identified through a literature review and ranked using the opinions of relevant industrial experts.

Barriers, minimal or no proper economic incentives, difficulty in ensuring product quality and costing of CE products are identified as top barriers to be eliminated first to boost the chances of successful implementation of circular economy practices in Indian automotive industries.

The study not only offers a roadmap on the order of elimination of barriers towards a circular economy but also provides insights from industrial experts on how these barriers can be eradicated and the ill effects of each barrier from an automotive industry perspective.

The authors develop a theoretical framework for barrier analysis for circular economy implementation in the Indian automotive sector using the classic AHP approach to identify the most critical barriers against successful implementation. Further, this study offers managerial implications on how these barriers can be eradicated in real.

Over the past several decades, instructional leadership has gradually gained increasing currency as a key role of school principals throughout much of the world. This is also the case in Malaysia where educational research, policy and practice have brought the instructional leadership role of the principal front and center. The purpose of this paper is to assess the conceptual models, research methods, and foci of scholars in the study of principal instructional leadership in Malaysia over the past 30 years.

Systematic methods were used to identify all studies conducted in Malaysia that had used the Principal Instructional Management Rating Scale (PIMRS) (Hallinger, 1982/1990/2015) as the data collection instrument. This search yielded a database of 120 studies completed between 1989 and 2016 written in both English and Bahasa Malay. Common data were extracted from the 120 research reports, coded and entered into a MS Excel spreadsheet for analysis. Quantitative methods were employed to analyze modal trends and synthesize patterns in the data across the studies.

The search identified 120 PIMRS studies, 90 percent of which had been conducted since 2005. This represented a surprisingly large corpus of studies. Over 75 percent of the Malaysian studies of principal instructional leadership had been conducted as graduate (master and doctoral) theses, relatively few of which had achieved publication in journals. The authors’ analysis found that most studies had used lower order (i.e. bivariate, direct effects) conceptual models and relied heavily on descriptive and simple correlational statistical tests. The lack of consistent results within the database of studies was attributed largely to limitations in research design and quality.

The 120 PIMRS studies conducted in Malaysia comprise a surprisingly large corpus of research on principal instructional leadership. Indeed, the Malaysian corpus is second only to the USA in terms of the number of PIMRS studies of principal instructional leadership. Nonetheless, limitations in the research models and methods employed in these studies suggest a need for stronger methodological training before Malaysian scholars can achieve the goal of contributing useful knowledge to the local and global knowledge base. Specific recommendations are offered for strengthening the quality of research.

The recent expansion of higher education in Malaysia – like other developing societies – has yielded progress in the scope of research production. However, numerous challenges remain in transforming the potential for useful knowledge production from graduate research into reality.

This is the first review of research on principal leadership conducted in Malaysia. The review follows efforts by scholars to systematically identify the boundaries of knowledge in educational leadership and management within East Asian societies (e.g. China, Singapore, Vietnam, Taiwan and Hong Kong). Moreover, this is the first review of research that examines the use of the PIMRS in a single society.

This literature review paper aims to discuss the impacts and measures taken on Covid-19 with respect to architecture, built form and its allied fields along with observations from around the world with the end results of its implementation.

Various research journals from Science Direct and Taylor and Francis among others were referred and reviewed to learn more on Covid-19 along with its impacts on people and their built environment. Keywords that aligned with the topic of interest like pandemic, Covid-19, coronavirus, urban spaces, built environment and built-up space were identified. Research papers that aligned with the scope of the paper and its keywords were found. An excel sheet with the basic data of these papers was written down. The essence of each of these articles were understood and linked with the topic in hand. A review of all these papers was written coherently to the topic. Future scope in this field of study was also identified.

It discusses the various measures taken around the world in built-up spaces along with the various measures given by researchers, architects and urban planners to mitigate and reduce the transmission of Covid-19 in the built environment and urban spaces. The discussed measures along with observations from around the world have also been discussed with its end results. Discussions and conclusions on these design strategies and recommendations are made with the anticipation of a paradigm shift due to post-pandemic changes. Current scenarios of public spaces in densely populated countries are discussed. Future scope in this ongoing field of study includes measures that can be taken in specific to some particular built-up typologies like markets, theaters, parks, bazaars, etc.

The limitation of this study is the restricting of the study of Covid-19 to only architectural, urban and public realm scales. The study does not facilitate the involvement of other fields and their influence with Covid-19.

This paper seeks to ascertain the effectiveness of a two-week-long faculty development programme (FDP), organized by Indira Gandhi National Open University (IGNOU), for teachers of the open and distance learning (ODL) system, with the aim of upgrading their knowledge and skills for developing print self-learning materials (SLMs). The specific aim of this study is to ascertain whether the objectives of the FDP have been achieved, to examine the effectiveness of the training programme and to suggest measures for improvement in future FDPs regarding the design and development of print SLMs.

The study was conducted using a descriptive survey research method, through semi-structured questionnaires and adopted purposive sampling. The first survey was conducted immediately after the completion of the programme, in order to collect feedback from the trainees, while the second survey was conducted after six months of the FDP, using the follow-up approach, so that more reliable and authentic results could be obtained.

The outcomes of the study revealed that the training had been effective in imparting appropriate knowledge and skills to the trainees, with respect to designing print SLMs. However, certain gaps were also identified and have been reported in this paper. Key suggestions have been made to address the shortcomings and improve forthcoming FDPs.

The present research focused on a specific training programme regarding the design and development of SLMs. Therefore, only the teachers and academics who participated in this specialized training activity were considered for the collection of feedback.

The recommendations of this work may be useful for the trainers, FDP coordinators, training institutions and ODL policymakers for planning and designing effective staff development activities for teachers and academics working in ODL institutions. These would be especially useful in the design of FDPs, aimed at orienting teachers who are involved in curriculum planning, design and development of learning resources.

This study is an original research based on the empirical primary data obtained by the researchers. As the largest open university in the world, IGNOU has been playing a key role in staff development for and in ODL in developing countries. This evaluative study of a specialized FDP in the area of SLM design and development is a significant work that may be valuable for planning the staff development strategies and building a training evaluation mechanism.
