A nation's grip on technology is a direct reflection of its industrial capabilities, hence, economic strength. Ghana, like many sub-Saharan Africa countries, aspired to develop its industrial base since inception as a nation. Such an aspiration was deemed by this study to require a concerted policy framework in technology creation/production/manufacturing intertwined with cultural underpinnings. Industry requires the use of technology and technology must necessarily be manufactured, again, through the application of technology. However, the issue of technology has been problematic in the African regions......

In a given work there is presented a solution of the significant problem – the improvement of silikomarganse guality by means of release of metal in the ladie with slag placed into it, which is previously covered with limestone layer. In order to improve the guality control there was developed and applied in manufacturing by authors new method of avtomatically control oif limestone humidity in the drying camera that also together with a new refining method results in maximum decrease of the waste produchs and of the harmful impurities contents in silikomarganese.

This study examines how different bath temperatures, specifically Selected Vegetable oil, water, palm kernel oil, engine oil, and diesel, affect the cooling rates, mechanical properties, and microstructure of quenched steel samples. Quenching is a widely used heat treatment process employed in steel machine components to improve their mechanical properties and increase their longevity. During quenching, heat is rapidly transferred from the hot metal component to the quenchant, resulting in a rapid decrease in temperature and inducing phase transformation in the metal. In this research, the steel samples were heated to an austenitizing temperature of 730°C, and alternative quenching methods were applied alongside water.......

The doors and windows of traditional houses in China are an important part of Chinese vernacular culture. This paper will take a look at the artistic characteristics and historical and cultural background of traditional residential doors and windows. In this paper, we study the doors and windows of the ancient buildings of Jingtai Village, such as the stone pagoda at the village gate, the old house Xi Lu, and the Mo Zhuang, based on the artistic characteristics and historical and cultural background of the decoration of traditional residential doors and windows. The study is summarised by means of field research and historical data. The study will then explain the traditional symbolism and stories of the decorative art of the doors and windows of the traditional houses in Jingtai Village, and analyse the practical, artistic and historical-cultural characteristics of the decorative art of the doors and windows of the traditional houses, as well as the ways and means of conservation.

Background: Mining is an essential industry for supporting economic and societal development, but it does not come without environmental consequences. One of the most significant environmental impacts of mining is the fact that blasting practices used to facilitate the extraction of ore, can wreak havoc on buildings and other structures located in and around the affected mine site. This paper discusses the effects of mining blast on buildings, including the force of the blast wave, vibrations caused by the blast. A proposed equation is evaluated using field measurements results obtained from the Multi-channel process. Also, the comparison of field results with International Building Codes and others is presented.
