Abstract: This research investigates the physical and engineering properties of soil in Uposhohor, Bogura Sadar, Bangladesh, to assess its suitability for multi-storey building foundations. Comprehensive field investigations and laboratory tests were conducted, revealing that the moisture content of the soil ranges from 17.6% to 34.41%, with an optimum moisture content between 17.6% and 18.4% corresponding to maximum dry densities of 1.73 to 1.81 kPa. The specific gravity values ranged from 2.50 to 2.71, and the coefficients of uniformity and curvature were found to be 11.75 to 15.13 and 0.41 to 1.10, respectively. Cohesion values varied from 8.67 to 21.45 kPa, while the angle of internal friction ranged from 13.34 to 35.62 degrees. The bearing capacity of the soil was determined to be between 280.45 kPa and 1250.31 kPa, indicating a high capacity for supporting building loads. The study concludes that the soil in Uposhohor has sufficient bearing capacity for the construction of multi-storey buildings, eliminating the necessity for deep foundation systems such as piles. It recommends a tailored foundation system along with a monitoring program to ensure the safety and stability of constructions. The findings provide essential insights for engineers and architects involved in designing multi-storey buildings in the area and can serve as a reference for future geotechnical research in the region.

Abstract: The token economy is taking shape and has the ability to totally transform the financial and banking sectors. However, tokens are not new and can be traced back more than a century. This paper identifies what tokens are emerging, the technology that supports them, and the international transactions costs they derive when compare with conventional banks. The paper compares the current day licensing framework of Australia, European Union, United Kingdom and the United States. It demonstrates how the current licensing frameworks for these jurisdictions is far from being settled, and is going through a significant shift politically and governments embrace tokens. If fully realized, tokens will transform the existing way in which payments, settlements and clearing is undertaken. Tokenization of the financial sector alone offers the potential opportunity for significant gains in reducing transactions costs and time. However, as with anything undertaken over the Internet, there are risks associated with cybersecurity. The paper further demonstrates that the estimated contribution token will provide the overall international economy for tokenizing trade finance, public procurement and employment compensation, will be significant. It is expected to add an enormous amount of wealth to nation states. Yet, the paper concludes that there is more work required, and urgent research is needed to fully understand the economic impact of tokens.

Abstract: 2,4,6-Trinitrotoluene (TNT) is an explosive that is well known for its stable nature, performance, and reliability. It is used in the military and mining industries as it can be cast into various shapes due to its ease of processing at its melting temperature of 80 to 82°C. It can be processed safely within melting temperature without the risk of thermal and impact-related initiation. Despite these properties, casting defect-free charges of uniform density is challenging. Hence, there is a need for targeted quality control measures and process optimisation to minimise density variations and defect formation in manufacturing. In this work the defects formation is mapped for a 10 kg anti-tank landmine, this is done by melting and casting TNT into a 10 kg anti-tank landmine fibre glass mould without any controlled cooling method. The melting and cooling temperature profiles of the TNT casing process were manually monitored using an infrared camera and the process was simulated using COMSOL Multiphysics. The resulting cast was characterised by Vidisco foXRayzor Digital X-Ray and Irdium-192 (192lr) radioactive source. The findings from this study depicted a dense structure at the mould’s margins compared to the booster centre. The less dense area also showed a high proportion of defects which were attributed to shrinkage during cooling.
