Groundwater depletion is a problem in many parts the world. We developed an approach to investigate drivers of groundwater data-scarce regions. The combines natural and human-induced drivers, with latter focusing on link between human activities government policies. tested Wadi Zabid, Yemen.

First, as many ecological services are unique, does the environment have an “essential” role in sustaining human welfare, and ...
Regulatory CD4(+) T cells have been shown to be important in limiting immune responses, but their role in respiratory viral infections has received little attention. Here we observed that following respiratory syncytial virus (RSV) infection, CD4(+) Foxp3(+) CD25(+) natural regulatory T-cell numbers increased in the bronchoalveolar lavage fluid, lung, mediastinal lymph nodes, and spleen. The de...

In recent years Genuine Savings (GS) has emerged as an indicator of weak sustainability and predictor socio-economic well-being. This paper presents the first long-term GS estimates for Norway, covering period from 1865 until 2018. The preliminary results indicate unsustainable development throughout most leading up to Second World War positive since 1946, with a single exception in 1992. resul...
How important is resource depletion (e.g. depletion of target cells) in controlling infection within a host? And how can we distinguish between resource depletion and other mechanisms that may contribute to decline of pathogen load or lead to pathogen clearance? In this paper we examine data from a previously published experiment. In this experiment, mice were infected with influenza virus carr...
