The purpose of this paper is to investigate the combined effects of slip and rheological parameters on the flow and heat transfer of the Herschel-Bulkley fluid.

The combinative dimensionless parameter method is introduced into the equations of the slip flow and heat transfer to make the discussion more comprehensive. More specifically, the slip and rheological parameters are transformed into the dimensionless slip number as well as Herschel-Bulkley number. We solve the dimensionless equations and then focus on the effects of these parameters on the slip flow and heat transfer.

The results show that, for a given value of Herschel-Bulkley number, there is a finite critical value of slip number at which the pressure gradient reaches the lowest value and both the dimensionless yield radius and slip velocity become 1. Meanwhile, the Nusselt number tends to be infinite at this critical value of slip number. For the case of slip, the Nusselt number also approaches infinity at a finite critical value of Herschel-Bulkley number. Furthermore, the dimensionless velocity as well as temperature of the yield pseudoplastic fluid with higher slip number is lower within a small radius but becomes higher near the wall. Meanwhile, from the velocity and temperature profiles, the effect of Herschel-Bulkley number on these two parameters of the Bingham fluid at the smaller radius is opposite.

These associated expressions can be generalized to the flow and heat transfer of a Herschel-Bulkley fluid under slip boundary condition. It can provide a reference for the engineering application relating to the heat transfer and flow of a Herschel-Bulkley fluid. Meanwhile, it also suggests some revelations for dealing with this similar problem.

This paper aims to explore how stolen Indian antiquities were purchased by a major Australian collecting institution, despite cultural protection policies designed to prevent such inappropriate acquisitions. Using the acquisition of the Dancing Shiva as a case study, the purpose of this paper is to examine how collecting institutions such as the National Gallery of Australia experience difficulty when determining legal title through provenance research. The impact of incautious provenance research produces significant risk to the institution including damaging its social responsibility credentials and reputation when the acquisition is discovered to be stolen.

This research applies a qualitative case study method and analysis of sourced official policy documents, personal communication with actors involved with the case, media reports and published institutional statements.

This work identifies four contributing factors that resulted in the National Gallery of Australia’s acquisition of stolen Indian artefacts: a misguided level of trust of the art dealer based on his professional reputation; a problematic motivation to expand the gallery’s Asian art collection; a less transparent and judicious acquisition process; and a collaboration deficiency with cultural institutions in India. Crime preventative methods would appear to be a strategic priority to counter art crime of this nature.

Additional research into how collecting institutions can be effectively supported to develop and implement crime preventative methods, especially less-resourced institutions, can potentially further enhance cultural heritage protection.

Fostering a higher degree of transparency and institutional collaboration can enhance cultural heritage protection, develop a greater level of institutional ethics and social responsibility and identify any potential criminal activity. Changing the culture of “owning” to “loaning” may provide a long-term solution for cultural heritage protection, rather than incentivising a black market with lucrative sums of money paid for artefacts.

Art crime involving the illegal trade of antiquities is often misinterpreted as a victimless crime with no real harm to individuals. The loss of a temple deity statue produces significant spiritual anguish for the Indian community, as the statue is representative not only of their God but also of place. Collecting institutions have a social responsibility to prioritise robust provenance policy and acquisition practices above collection priorities.

Art crime is a relatively new area within criminology. This work examines issues involving major collecting institutions acquiring stolen cultural heritage artefacts and the impact art crime has on institutions and communities. This paper unpacks how motivations for growing more prestigious collections can override cultural sensibilities and ethical frameworks established to protect cultural heritage. It highlights the liabilities associated with purchasing antiquities without significant due diligence regarding provenance research and safeguarding cultural heritage. It also emphasises the importance for collecting institutions to establish robust acquisition policies to protect the reputation of the institutions and the communities they represent.

This thesis deeply studies the impact mechanism of digital service trade on the high-quality development of the manufacturing industry from the aspects of technological innovation and industrial structure.

In this thesis, 40 countries from 2010 to 2020 were selected as samples, and the panel fixed-effect model and intermediary effect model were used to empirically analyze the impact path of digital service trade on the high-quality development of global manufacturing.

Overall, digital service trade has a positive impact on the high-quality development of the global manufacturing industry. Through the analysis of the intermediary effect mechanism, it is found that digital service trade can further positively affect the high-quality development of the global manufacturing industry by promoting technological innovation and industrial structure upgrading.

Based on the empirical results, targeted countermeasures and suggestions are given in this paper.

Through the test of national heterogeneity, it is found that in developing countries, digital service trade mainly acts on the high-quality development of the manufacturing industry by promoting industrial structure upgrading.

In developed countries, digital service trade mainly promotes the high-quality development of manufacturing through technological innovation; from the perspective of industry heterogeneity, the three service industries of information and communication technology (ICT), other business services and property have the intermediary effect of technological innovation and industrial structure.

This manuscript suggests that trade in digital services should be promoted as a national trade priority.

This study is part of the valorization of local materials and the reuse of industrial waste in construction. This study aims to improve the physical-mechanical properties of sand concrete. This work is a continuation of previous studies conducted on sand concrete, the purpose of which is to introduce industrial waste into this material. For this purpose, a glass waste in powder form is added.

This study is focused on the effect of adding glass powder (GP) whose mass percentage varies from 0 to 40% with an interval of 10% to target the right composition that ensures the best compromise between the characteristics studied.

The results found show that the workability and density of the studied concretes decreased with increasing GP dosage. Indeed, the optimal addition which constitutes the best compromise between the studied properties is 10% of GP. Improvements of up to about 9% in the case of flexural strength and about 18% in the case of compressive strength. The thermal conductivity has been reduced by 12.74%, the thermal diffusivity which characterizes the notion of thermal inertia has been reduced by about 4% and the specific heat mass has been reduced by 7.80%. Also, the shrinkage has been reduced by about 20%. The microstructure of the studied composite shows a good homogeneity between the aggregates. Finally, the addition of GP to sand concrete gives very encouraging results.

The interest of this study is in two parts. The first one is the exploitation of local materials: dune sand, river sand and limestone filler to meet the growing demand for construction materials. And the second one is the reuse of glass waste, in the form of powder (GP), to solve the environmental problem. All this participates in the improvement of the physical-mechanical properties of sand concrete and the extent of its response to the development of an economical structural concrete.
