An implementation study of oral and blood‐based HIV self‐testing and linkage to care among men in rural and peri‐urban KwaZulu‐Natal, South Africa

Journal of the International AIDS Society, Volume 23, Issue S2, June 2020., 2020
Abstract Introduction In South Africa, HIV‐infected men are less likely than women to test and know their status (the first UNAIDS “90‐90‐90” target), and men have worse outcomes across the HIV care cascade. HIV self‐testing (HIVST) may address this testing disparity but questions remain over the most effective distribution strategy and linkage ...

Acidification in the inland Pacific Northwest

Crops &Soils, Volume 48, Issue 2, Page 4-12, March‐April 2015., 2015
The dramatic rolling hills of the inland Pacific Northwest (iPNW), formed from deep deposits of volcanic ash and wind‐blown loess, feature some of the world's most productive soils. Alarmingly, a growing trend of extremely low‐pH values in these soils represents a serious threat to land quality, value, and productivity.
