The purpose of this conceptual paper was to investigate the contribution of the “Pipeline”, as a metaphor for building theory about Women-on-Boards (WoB) in the Arab world.

Narratives about women's progress in Arab countries were collected from a range of sources and content was analysed to identify emergent themes about pipeline.

Themes were identified of the pipeline metaphor that explained phenomena and generated solutions to employ, retain and advance women to board directorships; from higher education (“bulging”/“bursting” pipeline) through employment (“leaking” pipeline) to boardroom (“blocked” pipeline).

Generalisation of these study results is limited by geographical context of this research. An implication is for further international studies on metaphor identification for women's progress.

Relevant metaphor-in-use required to generate company policy and praxis towards WoB in the Arab world.

The first academic study to investigate the value of metaphor for effect on women's progress in Arab countries. Novel metaphor identification is proposed to think and see women's experiences in cultural context.

Taking a career capital approach, this paper addresses the issue of “pipeline block” frequently experienced by women seeking career advancement. Focusing on the Arab Middle East (AME) region, the authors take a contextually relevant multi-level approach to examine these issues.

The study uses a qualitative, interview-based approach, drawing on data obtained from women leaders from the AME region. Drawing on Bourdieu's capital-field-habitus framework, we explore how women in the AME developed career capital in particular organisational fields.

The findings show the importance of human and social capital, as well as the influence of habitus for women's career advancement in specific fields. The study also highlights the unique contribution of cultural capital in helping women to navigate organisational fields where it is necessary to both challenge, and conform to, traditional norms.

Limitations of the study include assumptions of homogeneity across countries of the AME, whereas differences are known to exist. Future research should consider these contextual differences, and also include a study of women who were not successful in gaining career advancement.

The study’s multi-level approach highlights practical implications for women, organisations and society. For organisations, the authors propose some context-relevant coaching strategies that can help women to attain leadership positions.

The study’s multi-level approach highlights practical implications for women, organisations,and society. Focusing on organisations, the authors propose some context-relevant coaching strategies that can help women to attain advancement in their careers.

The study demonstrates originality in the findings by showing how women overcome the pipeline block in relation to their career advancement. The use of the Bourdieusian framework, an in-depth qualitative approach, and the AME context also add to the study's originality.

The US fossil fuel industry is vulnerable to opposition from other sectors of the ruling class. Non-fossil fuel capitalists might conclude that climate breakdown jeopardizes their interests. State actors such as judges, regulators, and politicians may come to the same conclusion. However, these other elite actors are unlikely to take concerted collective action against fossil fuels in the absence of growing disruption by grassroots activists. Drawing from the history of the Obama, Trump, and Biden presidencies, I analyze the forces determining government climate policies and private-sector investments. I focus on how the climate and Indigenous movements have begun to force changes in the behavior of certain ruling-class interests. Of particular importance is these movements' progress in two areas: eroding the financial sector's willingness to fund and insure fossil fuels, and influencing judges and regulators to take actions that further undermine investors' confidence in fossil fuels. Our future hinges largely on whether the movements can build on these victories while expanding their base within labor unions and other strategically positioned sectors.

The purpose of this paper is to present a new technique for monitoring gas leakage in underground pipelines to prevent dangerous explosions.

A novel system for monitoring methane concentration in underground spaces was developed by integrating the multi-channeled air sampling method with an infrared gas sensor. A pipe installation methodology (without excavation) was established and verified accordingly.

The proposed approach was proven successful in reducing the quantity of sensors needed for real-time monitoring of underground pipeline leakage by about 80 per cent. Furthermore, this system lowers total operational cost by as much as 60 per cent.

The results presented here represent a possible solution to reducing the public safety risks associated with explosions and fires caused by pipeline leakage in underground spaces. Its total cost is low and its monitoring efficiency is high.

The purpose of this study is to develop a robot for non-destructive testing of the pipelines to improve its reliability and reduce the loss of products due to cracks, corrosions, etc.

In this study, an inline inspection robot was developed for crack and corrosion detection in the pipeline. The developed robot consists of ultrasonic sensors to avoid obstacles, a visual aid with high resolution to view real time images and colour sensors for corrosion detection. The Autodesk inventor software was used for the drafting and solid modelling of the robot. A dummy pipe of 500 mm diameter and 2,000 mm length with induced cracks and corrosion was fabricated to test the robot. The colour sensors placed at each side of the robot were used to detect corrosion in the dummy pipe whilst the image processing was done to analyse the crack, as well as the type and depth of corrosion present in the dummy pipe.

The results obtained show the ability of the developed robot to detect cracks and determine the crack growth in the pipeline in addition to its ability to determine corrosion.

Hence, the study provides a diagnostic tool for detecting pipeline defects and analysing the extent of defects to determine the fatigue rate and the useful life of the pipeline.

The novelties of this study is based on the fact that it was designed to avoid obstacles and check for cracks, leakage and corrosion in pipelines autonomously. It has visual aid that makes it possible to see the interior of the pipe. This makes it easier to identify the defect and the location of the defects before a catastrophic failure. The device is also equipped with sensors, which can detect defects and send the signal to a control system, as well as a Bluetooth device so the operator can have real time information about the state and integrity of the pipelines. The system is also integrated with a Bluetooth device, which permits its compatibility with Android and other mobile applications. Thus, the enabled user can send a command to query the state of the pipeline at any location with the feedback received in the form of short message service. Hence, this study offers contribution in the development of an independent (self-governing) system with the capability to autonomously detect defects in pipe walls and effectively communicate feedback to the authorised users. The prototype model for the evaluation of pipeline integrity will bring about a more proactive way to detect pipeline defects so that effort can be geared towards its restoration before it becomes a major problem, which will subsequently affect productivity and incur losses.
