Integrated circuits for wireless sensor nodes (WSNs) targeting the Internet-of-Things (IoT) paradigm require ultralow-power consumption for energy-harvesting operation and low die area for low-cost nodes. As the IoT calls for the deployment of trillions of WSNs, minimizing the carbon footprint for WSN chip manufacturing further emerges as a third target in a design-for-the-environment (DfE) per...

BACKGROUND The present study was done in order to compare balance and footprint parameters in two groups of normal and overweight children. METHODS This semi-experimental study included randomly selected 22 male children (11 normal and 11 overweight boys). To measure the footprint parameters, an ink paper system was used, i.e., after putting their feet in the ink, the subjects were asked to s...

Many techniques of arthroscopic rotator cuff repair have been described. No significant differences in clinical outcomes or rerupture rates have been observed when comparing single-row with double-row methods. Not all single- and double-row repairs are the same. The details of the technique used are crucial. It has been shown that the suture-tendon interface is the weakest point of the reconstr...

OBJECTIVES We estimated associations between objectively determined neighbourhood 'walkability' attributes and accelerometer-derived sedentary time (ST) by sex, city or type of day. DESIGN A cross-sectional study. SETTING The URBAN (Understanding the Relationship between Activity and Neighbourhoods) study was conducted in 48 neighbourhoods across four cities in New Zealand (August 2008 to O...

We have proposed a new ultra-compact optical demultiplexer based on metal-insulator-metal plasmonic waveguides aperture-coupled to the ring resonators. Our proposed device has high performance, small footprint, and high potential for integration and development to more channels.

Water Footprint Assessment is a fast-growing field of research, but as yet little attention has been paid to the uncertainties involved. This study investigates the sensitivity of and uncertainty in crop water footprint (in m3 t−1) estimates related to uncertainties in important input variables. The study focuses on the green (from rainfall) and blue (from irrigation) water footprint of produci...

As population and water demand increase, there is a growing need for alternative water supplies from water reuse and desalination systems. These systems are beneficial to water augmentation; however, there are concerns related to their carbon footprint. This study compiles the reported carbon footprint of these systems from existing literature, recognizes general trends of carbon footprint of w...

Low carbon footprint energy sources such as solar and wind power typically suffer from unpredictable or limited availability. By globally distributing a number of these renewable sources, these effects can largely be compensated for. We look at the feasibility of this approach for powering already distributed data centers in order to operate at a reduced total carbon footprint. From our study w...
