Objectives: Understanding the coronavirus disease 2019 (COVID-19) knowledge and personal preventive behaviors of younger individuals is important as it can affect not only their own health but also the health of other potentially more vulnerable individuals. The aims of this study were to explore the knowledge of teenagers and young adults about COVID-19 and assess their personal preventive behavior.

Methods: We developed a 14-item questionnaire to conduct a cross-sectional online survey.

Selective separation of copper over solder alloy from waste printed circuit boards leach solution.

The printed circuit boards (PCBs) from electronic waste are important resource, since the PCBs contain precious metals such as gold, copper, tin, silver, platinum and so forth. In addition to the economic point of view, the presence of lead turns this scrap into dangerous to environment. This study was conducted as part of the development of a novel process for selective recovery of copper over tin and lead from printed circuit boards by HBF leaching.

Energy Drink Consumption and Cardiac Complications: A Case for Caution.
