Introduction: Malaria is a killer disease in the tropical environment; artemisinin-based combination therapies (ACTs) play a central role in treating malaria. Thus, the supply and presence of ACT drugs in hospitals are a key feature in the fight against malaria. Supply chain management literature has focused on the private sector, and less attention has been paid to the public sector, especially hospitals.

Owing to their strong bond with anions, rare earth elements (REEs) are prime contenders in wastewater treatment to meet the stringent phosphorus (P) effluent quality requirements. REEs outcompete traditional metals to abate phosphorus. The application of lanthanides in wastewater treatment is mainly through adsorption, where REEs are incorporated into a carrier matrix to improve the adsorption capacity.

Radionuclides Ra, Th, and K can be found in various concentrations in the surface soil. High concentrations of radionuclides in the surface soil may cause radiological risks. This study investigated natural radioactivity levels and artificial radionuclide (Cs) levels in the Istanbul University-Cerrahpasa, Avcilar region, Istanbul, Turkey.

In the race to deliver clean water to communities through potable water reuse, disinfection and water quality assessment are and will continue to be fundamental factors. There are over 700 disinfection byproducts (DBPs) in water; evaluating each compound is practically impossible and very time consuming. A bioanalytical approach could be an answer to this challenge.

Rare earth element (REE) coagulants are prime contenders in wastewater treatment plants to remove phosphorus; unlike typical coagulants, they are not affected by pH. However, the use of REEs in wastewater treatment could mean increased human exposure to lanthanides (Ln) through wastewater effluent discharge to the environment or through water reuse. Information on the toxicity of lanthanides is scarce and, where available, there are conflicting views.

Introduction: This study sought to examine the contribution of relationship building (in terms of collaboration, information sharing and supply chain interdependence) on the availability of malaria treatment pills in public hospitals in Sub-Saharan Africa using data from Uganda.

Methods: By means of a cross-sectional survey research design, the study used a questionnaire strategy to collect quantitative data. Out of the 320 questionnaires that were distributed in 40 public hospitals, 283 were answered and returned, which yielded an 88% response rate.

Globally, there are increased threats to available freshwater resources due to pollution, climate change, and increased demand from population growth. Phosphorus is one of the essential nutrients required for animal and plant growth. However, when it is released into freshwater resources in excess amounts, it can become a pollutant through eutrophication.

Municipal solid waste is a problem to developed and developing cities in the world. If municipal solid waste is not managed well, it can be a source of numerous contaminants to water, air, and soil. Although landfill is at the bottom in terms of priorities of municipal solid waste management techniques, its applicability cannot be neglected in developing economies.
