Sand and permanent moulds were fabricated and used to produce Aluminium rods. The test samples from cast rods were subjected to Tensile and Hardness tests. The results obtained showed better Tensile and Hardness properties, in the sand cast samples than that of permanent cast samples. The hardness of permanent and sand casting varied from 66.5Hv to 70.0Hv. Also, Ultimate Tensile Strength increased from 108.78MPa in permanent casting to 161.97MPa in sand casting. Conversely, the Tensile and Hardness properties of the cast products improved from those of permanent casting to sand casting. Therefore, sand cast products could be used in as-cast condition in engineering applications requiring better quality parts while permanent casting may be used in as-cast condition for nonengineering applications or engineering applications requiring less quality parts.

In this paper, a reliable encoding and decoding algorithm of sparse lattice information based on printing-quantum-dots image is proposed. The encoding algorithm use a combination of information encryption, Low-Density-Parity-Check (LDPC) encoding, interleaved encoding and frame synchronization encoding, generating the printing-quantumdots image. The decoding algorithm is the inverse process of the encoding algorithm, and can partially intercept the printing-quantum-dots image for reading. From the experimental results, it can be concluded that the combined coding scheme has better error-correcting ability and imperceptibility, the SSIM of before and after embedding reaches above 0.99, and the PSNR reaches above 54dB. Moreover, it can extract the printingquantum-dots from the cover image, and read the hidden information. Besides, compared to BCH code, and convolutional code, it has high coding efficiency, prominent coding efficiency, as well as faster decoding speed.

This was aimed at collecting data from welding practitioners on their adherences to safety precautions in the practice welding activities. 195 out 200 administered questionnaires were retrieved and analysed. The results of the analysis revealed that,the majority of welding practitioners in the metropolis lacks the basic education about the code of practice in welding and neglect most necessary safety precautions which arose due to lack of regulations and enforcement of adherences to codes by any governmental agency. It was then recommended that government should regulate, enforce adherences to codes and support the practitioners within the metropolis.

The sociological scientific foundation of the policies and practices of the new types of social assistance, in accordance with the realities of the beginning of the millennium, being a necessity. Under the conditions of shaking structural or universalist solutions and paradigms, advancing postmodernist paradigms and social solutions, sociologists must increasingly resort to visions, concepts, theories or methods such as existentialist or personalist-humanist, often marginalized in periods of economic and social well-being. , when redistribution policies and universalist-solidarity mechanisms automatically solve many social problems. That is precisely those paradigms that highlight the valences and role of the small group, the small community, the context and the person in social determinism, in the explanation of the social vulnerability and problem.

Finding an energy-efficient solution for cooling needs poses a considerable challenge for engineers. In this article,the performancesof a phase change material-based (PCM) thermal energy storage (TES)installed in a telecommunication site areevaluated with the design methods and control optimization. Three representative days of the year (free-cooling, expanded free-cooling and summer period) and their possible savings,as well as the savings of an entire year period are investigated and showcased. During the freecooling period 83,1% cooling associated electricity consumption was saved with the added indirect free-cooling system through the TES. For the expanded free-cooling period, the TES was charged using the free-cooling and discharged when free-cooling was not possible anymore, accounting for 78,7% cooling associated electricity saving. During the summer period only the chiller's efficiency was optimized, resulting in 17,1% saving. During 2019. 57,7% and during 2020. 54,8% cooling associated electricity was saved.
