Global perspectives on observing ocean boundary current systems

Ocean boundary current systems are key components of the climate system, are hometo highly productive ecosystems, and have numerous societal impacts. Establishmentof a global network of boundary current observing systems is a critical part of ongoingdevelopment of the Global Ocean Observing System. The characteristics of boundarycurrent systems are reviewed, focusing on scientific and societal motivations forsustained observing. Techniques currently used to observe boundary current systemsare reviewed, followed by a census of the current state of boundary current observingsystems globally. The next steps in the development of boundary current observingsystems are considered, leading to several specific recommendations

International AIDS Society global scientific strategy: towards an HIV cure 2016

Antiretroviral therapy is not curative. Given the challenges in providing lifelong therapy to a global population of more than 35 million people living with HIV, there is intense interest in developing a cure for HIV infection. The International AIDS Society convened a group of international experts to develop a scientific strategy for research towards an HIV cure. This Perspective summarizes the group's strategy

Water purification system using a heat pump

This paper presents a way to produce purified water with the same quality from the conventional water distiller and the advantage of saving energy and cooling water. Purified water was obtained by air dehumidifying with the aid of a heat pump and an adiabatic humidification system. The designed equipment is composed of two parts: a vapor compression heat pump and a chamber where the recirculated air gets humidified. (C) 2011 Elsevier Ltd. All rights reserved.31163354335
