Article history: Received 27 July 2009 Received in revised form 1 September 2009 Accepted 16 September 2009 Available online 3 October 2009 Well-being is a construct spanning multiple disciplines including psychology, economics, health, and public policy. In many ways, well-being is a nexus of inter-correlated variables, much like the g nexus. Here, we created an index of well-being for the geo...

Recent studies of calorie restriction in several organisms demonstrate an increase in mitochondrial activity that is associated with the salutary effects of this dietary restriction regimen. In this Essay, I speculate on how an increase in mitochondrial activity might provide benefit and discuss how diet, mitochondria, and sirtuins might interact in a pathway to slow aging and associated diseases.

This paper introduces Madeleine II, a new adaptive and portable multi-protocol implementation of the Madeleine communication library. Madeleine II has the ability to control multiple network interfaces (BIP, SISCI, VIA) and multiple network adapters (Ethernet, Myrinet, SCI) within the same application session. We report on performance measurements obtained using BIP/Myrinet and SISCI/SCI and we...

Globally, natural resources are increasingly under pressure, especially due to population growth, economic growth and transformation as well as climate change. As a result, the water, energy, and food (WEF) nexus approach has emerged to understand interdependencies and commonly manage resources within a multi-scale and multi-level framework. In Sub-Saharan Africa, the high and growing consumpti...

This paper is proposing a new approach to record physiological parameters such as ECG, EMG,BVP ,SC from a remote location & Transmitting these signals to a medical practitioner .In this new proposed approach, physiological signal monitoring has been carried out using various sensors, Nexus 10 & Biotrace Software. These physiological signals would also be useful in training the functioning of au...

The 2 major cellular lipid species, sterols and fatty acids, have many roles in physiology. Not only are they essential structural components of eukaryotic cell membranes, but they are also used as sources for cellular energy, serve as precursors for biosynthesis of key cellular macromolecules, are strategically used as post-translational modifications of many proteins, and function as signalin...

Effective HIV prevention requires the protection and empowerment of marginalized groups at high risk of infection. However, many policies persist that stigmatize these groups and hinder HIV prevention efforts, including HIV-related travel restrictions. In the Republic of Korea, which requires HIV tests for certain visa categories, these restrictions negatively affect the national HIV response a...

Synthetic nitrogen (N) fertilizer has enabled modern agriculture to greatly improve human nutrition during the twentieth century, but it has also created unintended human health and environmental pollution challenges for the twentyfirst century. Averaged globally, about half of the fertilizer-N applied to farms is removed with the crops, while the other half remains in the soil or is lost from ...

The two major conservation issues for drylands of Africa are habitat loss or degradation and habitat fragmentation, largely from agriculture, charcoal production, and infrastructural development. A key question for management is how these landscapes can retain their critical ecological functions and services, while simultaneously supporting resilient livelihoods. It is a clear nexus question in...
