Abstract

This research work successfully reviewed twenty-five papers on waste rubber tyres and their related areas. The chemical and physical properties of concrete constituents such as cement, water, sand and rubber crumbs were reviewed together with their mix ratios. The use of Tyre Rubber Crumbs (TRC) to replace coarse aggregates makes concrete construction work cheaper and its low water absorption rate improves the concrete mix properties such as compressive strength and workability. Hence, in road pavement construction, the use of TRC in asphalt modification is the best and smartest innovation for sustainable development and waste material reuse. This research showed that waste TRC are very essential in the replacement of some aggregates in the construction industries resulting in very high-quality construction and as well minimize construction costs.

Abstract

The virus pandemic COVID-19 outbreak brought a huge pressure to the public healthcare system worldwide, especially in developing African countries like Uganda. The Educational system and institutions were put on a standstill due to no quick countermeasures to make the environment clean and safe for normal activities to continue. This paper successfully and comprehensively reviewed the Bluetooth and smart disinfectant spraying robot that successfully controlled the spread of the deadly virus. It also detailed different components that made up the complete spraying robot systems and from this it was observed that spraying robot systems are made up of almost the same components for implementations but differs on program that is embedded on the microcontroller due to different functions. This programing differs based on the functions that the designer/programmer wants the robot to do despite using almost the same components. This research review paper will act as guide for future researchers when designing and implementing a mobile spraying robot.

Abstract

Renewable energy has been identified as a critical component of global efforts to address climate change, enhance energy security, and foster sustainable economic growth. As a result, many countries have implemented renewable energy policies to promote the development and deployment of renewable energy technologies. However, the impact of these policies on economic growth remains a subject of debate. This article provides a comparative analysis of renewable energy policies and their impact on economic growth. The study employs a systematic review of the literature and utilizes qualitative and quantitative methods to compare renewable energy policies and their economic impacts across different countries. The findings suggest that the impact of renewable energy policies on economic growth varies across countries and is influenced by factors such as policy design, institutional context, and economic structure. This research article finally, examined the challenges associated with implementing renewable energy policies, analyzed the implications of the findings for policymakers and further gave some potential solutions that will help the policymakers and future researchers.
