Abstract:
The interaction of unburnt gas flow induced in an explosion with an obstacle results in the production of turbulence downstream of the obstacle and the acceleration of the flame when it reaches this turbulence. Currently, there are inadequate experimental measurements of these turbulent flows in gas explosions due to transient nature of explosion flows and the connected harsh conditions. Hence, majority of measurements of turbulent properties downstream of obstacles are done using steady-state flows rather than transient flows. Consequently, an empirical based correlation to predict distance t

Abstract:
Previous studies on the influence of obstacle shapes in gas explosions involved mainly single obstacles whereas only a few studies focused on multi-obstacle with constant spacing between obstacles. This paper is aimed at studying the influence of obstacle spacing on two obstacles of various shapes in a tubular geometry using 10% methane-air mixtures. For single obstacles of 20% blockage, 1-flat-bar produced the highest explosion severity followed by a baffle disc and orifice plate. The reverse was the case for 30% obstacle blockage. In case of double obstacle optimally spaced, 1-flat-bar produ

A new model for a Timoshenko plate contacting by the side surface or the edge of the bottom surface (with respect to the chosen coordinate system) with a rigid obstacle of a given configuration is justified. The non-deformable obstacle is defined by a cylindrical surface, the generators of which are perpendicular to the middle plane of the plate, as well as by a part of the plane that is parallel to the middle plane of the plate. A corresponding variational problem is formulated as a minimization of an energy functional over a non-convex set of admissible displacements. The set of admissible d

The maximum number of the obstacles in tandem array is 3 and the spacing between obstacles is 1d, 2d, or 4d. The free-stream Reynolds number ranges

To achieve the objectives of this highly complex, highly interdisciplinary, and innovative project, a permanent articulation of the scientific approach with the technical and design development took place, aiming the construction of the non- invasive evaluation method. Because it is an intricate project, it required cons

Abstract:
Although the Caribbean region relies heavily on its natural assets as sources of income, generally for tourism and in particular cases from agriculture and energy, environmental taxes in the region have been little studied. This paper therefore is intended to reflect the existing economic instruments in place for capturing the use (and abuse) of the regions environmental and natural resource assets to reflect the degree to which adopted actions have been effective. Data paucity has been highlighted as a major obstacle in permitting rigorous assessment; the report therefore draws on the availab

Abstract:
The article aims at assessing the current state of Saudi-Iranian relations and the reconciliation process taking place between the two Middle Eastern countries since 2021 by overviewing the main factors both on the domestic and international levels which can serve as either incentives for cooperation or obstacles. In the domestic realm, economic considerations are the primary drivers for both governments to get closer to each other. Regionally, the Yemeni conflict, Lebanese domestic politics, as well as the Iranian nuclear question are the most important issues affecting the process. In themse

Abstract:
Electric aviation (EA) has emerged as a promising alternative to mitigate the climate impacts of aviation. The Nordic countries aspire to lead the way in adoption of this new technology and have set ambitious targets for its implementation in the near future. However, numerous open questions and challenges must still be addressed before electric aviation can become reality. Is the political commitment in the Nordic Region sufficient to support those initiatives? Where will the necessary funding come from? Are the required technological advancements and infrastructure in place? These are among

Abstract:
When an inmate leaves prison following a sentence for terrorism offenses, their reintegration will depend on whether they can function as a relatively social member of their community. Obstacles such as stigmatization exist for all former convicts, but among steadfast extremists these barriers will be mutual, if they continue to perceive the ingroup-outgroup dichotomy that fed their extremism in the first place. A simple but effective means for determining the likelihood that returning prisoners will act prosocially towards the ‘other’ could be the use of so-called lab-in-field games, which pr

Abstract:
In addressing the critical challenge of systemic sustainability, this report explores the need for more than a one-size-fits-all approach in the Nordic Region. It investigates the role of change agency processes and the impact of policies and framework conditions on green transition changes in business sectors. Our two case studies reveal some of the bottlenecks and drivers of innovation and explore them from a systemic perspective and in different geographic scales, both from a place-based and place-less perspective. The methodology adopted in the report is comprehensive, including a deep div

Abstract:
In September 2015, Ghana along all UN member states endorsed the Agenda 2030 Sustainable Development Goals (SDGs) as the cardinal agenda towards achieving a prosperous global future. The SDGs are strongly interdependent, making progress in all goals essential for a country’s achievement of sustainable development. While Ghana and other West African nations have exhibited significant economic and democratic development post-independence. The judiciary system and related legal frameworks, as well as the lack of rule law and political will for safeguarding the human rights of its citizens, falls
