In an effort to bring the AIDS epidemic under control among the highest risk population of injecting drug users, Syringe/Needle Exchange Programs are being considered, developed and implemented. This paper looks at some of the programs in the United States in various stages of development. Also discussed will be the medical, social and political issues surrounding Needle Exchange Programs.

The scarcity of cost-effective and durable iridium-free anode electrocatalysts for the oxygen evolution reaction (OER) poses a significant challenge to the widespread application of the proton exchange membrane water electrolyzer (PEMWE). To address the electrochemical oxidation and dissolution issues of Ru-based electrocatalysts, an electron-donating modification strategy is developed to stabilize WRuO under harsh oxidative conditions. The optimized catalyst with a low Zirconium doping (Zr, 1 wt.

So the current production mode is featured by single well tank oil storage, oil tank truck transportation and manual tank truck scheduling.

Background: Global progress toward malaria elimination and eradication goals has stagnated in recent years, with many African countries reporting increases in malaria morbidity and mortality. Insecticide-treated nets and indoor residual spraying are effective, but the emergence and increased intensity of insecticide resistance and the challenge of outdoor transmission are undermining their impact. New tools are needed to get back on track towards global targets.

Purpose: This narrative review addresses post-2020, specific, complex challenges for use of and adherence to pre-exposure prophylaxis (PrEP) for HIV prevention among out-of-treatment people who use drugs (PWUD) at syringe services programs (SSPs).
Recent Findings: The COVID-19 pandemic and its associated changes to the provision of healthcare have significantly impacted HIV prevention, especially for PWUD. Through a synthesis of literature and clinical experience, we (1) characterize the operational changes imposed by the pandemic on SSPs that shaped the current HIV prevention landscape; (2) describe three levels of current challenges for PWUD, including consumer attitudes, non-medical and medical provider attitudes, and structural and scalability barriers; (3) characterize current models for PrEP in SSPs; and (4) offer practical recommendations for HIV prevention in harm reduction programs.

This near-infrared spectral dataset consists of 2,106 diverse mineral soil samples scanned, on average, on six different units of the same low-cost commercially available handheld spectrophotometer. Most soil samples were selected from the USDA NRCS National Soil Survey Center-Kellogg Soil Survey Laboratory (NSSC-KSSL) soil archives to represent the diversity of mineral soils (0-30 cm) found in the United States, while 90 samples were selected from Ghana, Kenya, and Nigeria to represent available African soils in the same archive. All scanning was performed on dried and sieved (<2 mm) soil samples.
