Solid waste management is a combination of techniques of disposing of, collecting, and recycling solid waste. Effective management of waste is vital for maintaining a sustainable environment. In countries where illegal disposal of waste and pollution are rampant, waste management is a way of dealing with deadly diseases such as cholera and malaria...... ReadMore -

The current research relates to the application of circular systems in the built environment. As of most projects related to the built environment (BE), and as it much fits in the framework of the circular economy (CE), this study will be applied for social well-being (WB) (goal no. 3 and No. 11 of the SDGs) for a particular age group. Sustainability is a delicate issue, for which sustainable construction should be the front-of-mind of any relevant company. Regarding older adults (OAs) as focusing populations, action plans must be carefully thought out; since sustainability is even more crucial for building a healthy environment for OAs. For this purpose, circular systems are promising. However, for an action plan to take effect, studying the various influential aspects, such as the support systems, locations, access to n.....

The last twenty years have seen, especially for residential buildings, the development and prototyping of several digitally manufactured light timber frame construction systems, that take advantage of digital fabrication techniques for the entire construction process, from design to construction. Today, there is a pressing need to provide spatial configurations that let users modify the internal distribution according to the changing of their needs over time. Following this research path, the proposed work aims to verify the degree of changeability and reversibility of these systems. These systems are compared in relation to the specific construction solutions adopted, the fabrication and assembly process used, the amount and variety of variables that affect the project workflow and other.....

Dispersion of Enterococcus faecalis was monitor in the study environment based on their heterogeneity in the creek, this shows serious concern base on rate of concentration from microbial analysis carried in the creek, the study determined the predominant factors that developed the heterogeneous dispersion in the transport of Enterococcus faecalis in the study area, this condition generated exponential phase based on the effect of the dispersion through the heterogeneous velocities of the creek, this expression implies that the migration and other causes of the contaminant deposition are influenced by these factors, the growth rate from exponential phase including high to low concentration are determined based on this predominant influential parameters, the derived modeling system expressed the behaviour of the microbes, this was ca.....
