Design of a Hydroelectronic Solar‐Tracking System for Solar Panels

Energy Science &Engineering, EarlyView.
A prototype of a passive solar‐tracking system utilizing buoyant force based on water level was developed, and its MATLAB/Simulink model was implemented. This study is expected to encourage researchers to design solar‐tracking mechanisms using metals with different thermal expansion coefficients, air, oil, and other fluids. ABSTRACT This study presents

Unintended Consequences of Life‐Saving Pharmaceutical Innovations: How HAART Led to the Resurgence of Syphilis

Health Economics, EarlyView.
ABSTRACT Syphilis, a sexually transmitted infection that can lead to serious health complications, was almost eliminated in the United States by 2000. But since then, its incidence began to increase, recently reaching a 60‐year peak. We suggest that the introduction of the highly active antiretroviral therapy (HAART) drug regimen, which transformed HIV
