Law is the core discipline of society as well as playing a vital role in any organization which is working and exists in the World. International law and trade are the backbones of global organizations. In this present discussion, secondary data was used. Data were obtained from secondary sources, especially from the law discipline research article, and from authentic and reliable sources. In the research article, the law oriented international organizations were the main targeted respondents. The importance of the law is because there are many motivations behind why countries and individuals decide to exchange and carry on with work globally instead of confining themselves in an undertaking to secure homegrown industry. Motivations to exchange incorporate the need to acquire normal assets, items, or administrations, in any case, inaccessible locally; the craving to get similar items more inexpensively than the expense of locally delivered merchandise; the longing to accomplish a monetary advantage by sending out homegrown regular assets, items or administrations which pay for the expense of imports; the longing to assist less beneficial countries with accomplishing advancement; and the need to keep up with military or political partnerships with exchanging countries. The present study gives an outline of international exchanges and business law and the various homegrown and global associations engaged with the guideline of worldwide exchange. It likewise suggests a synopsis of the modalities of the development of an arrangement for the global exchanging of a decent, involving the advantages and entanglements of undertaking worldwide deals.

The objective of this study was to review the mainrainwater harvesting and treatment systems through a bibliometric analysis from2000-2021. A bibliometric analysis was used in the R program and VOS viewer,the query involved titles, abstracts, and keywords during the last 20 years(2000-2021). The results indicate that from 2013 onwards, interest in thistopic increased. 13% of the publicationsbelong to the academic journal Journal of Cleaner Production. The main authorleading the publications is Ghisi, from Brazil, who conducted 24 types ofresearch and one of his papers reached 95 citations. In conclusion, there isevidence of the need to strengthen research in developing countries tocontribute to water saving and supply in areas that do not have drinkingwater.

Planted roofs have been investigated as a passive cooling technical for the energy efficiency purpose in buildings. More quantitative data on this topic are required to solve a lack of information for many specific regions. This study is focused to a numerical investigation of the thermal comfort inside a green roof rectangular ventilated cavity in a hot and humid climate as the one of Lomé in west Africa. The left vertical is heated and partly saturated with water to provide humidification of the indoor air. Transfer dimensionless equations are solved using an implicit finite difference scheme, Thomas algorithm and the Gauss Seidel iterative method. We analyze the effects of inlet airflow on the thermal process inside the ventilated and planted enclosure have been investigated. The comfort temperature range deduced from data is: 25°C< Tc < 27°, that of the indoor air humidity is: 49% < Hr <60%. The different ranges obtained are significant and lead to improve inside thermal comfort. The solar flux 350 W.m-2, the average value in case of Lomé city, was used to establish a heat transfer correlation to predict heat transfer through the roof with a relative error not exceeding 4%. This model can be very useful for engineers in the design and optimization stage of a green roof in practical buildings.
