Nitrogen removal in constructed wetland systems

Abstract: Since the mid 1990s, constructed wetlands have been increasingly used as a low-energy ‘green’ technique, in the treatment of wastewater and stormwater, driven by the rising cost of fossil fuels and increasing concern about climate change. Among various applications of these wetlands, a significant area is the removal of nitrogenous pollutants to protect the water environment and to enable effective reclamation and reuse of the wastewater. This paper provides a review of the current state of nitrogen removal technology, focusing on existing types of wetlands, the mechanisms of nitrogen removal, major environmental factors relative to nitrogen removal, and the operation and management of the wetlands.

Chipless RFID: Bar Code of the Future

Abstract: Radio-frequency identification (RFID) is a wireless data capturing technique that utilizes radio frequency (RF) waves for automatic identification of objects. RFID relies on RF waves for data transmission between the data carrying device, called the RFID tag, and the interrogator.

A comparison of the Assessment of Quality of Life (AQoL) with four other generic utility instruments

Abstract: As part of the validation of the Assessment of Quality of Life (AQoL) instrument comparisons were made between five multiattribute utility (MAU) instruments, each purporting to measure health-related quality of life (HRQoL). These were the AQoL, the Canadian Health Utilities Index (HUI) 3, the Finnish 15D, the EQ-5D (formerly the EuroQoL) and the SF6D (derived from the SF-36). The paper compares absolute utility scores, instrument sensitivity, and incremental differences in measured utility between different instruments predicted by different individuals. The AQoL predicted utilities are similar to those from the HUI3 and EQ-5D. By contrast the 15D and SF6D predict systematically higher utilities, and the differences between individuals are significantly smaller. There is some evidence that the AQoL has greater sensitivity to health states than other instruments. It is concluded that at present no single MAU instrument can claim to be the 'gold standard', and that researchers should select an instrument sensitive to the health states they are investigating. Caution should be exercised in treating any of the instrument scores as representing a trade-off between length of life and HRQoL.

Measurement of mobility in dual-gated MoS2 transistors

Abstract: Atomically thin semiconducting MoS2 is of great interest for high-performance flexible electronic and optoelectronic devices. Initial measurements using back-gated field-effect transistor (FET) structures on SiO2 yielded mobility of 1-50 cm^2/Vs for few-layer MoS2[1, 2]. Initial measurements using back-gated field-effect transistor (FET) structures on SiO2 yielded mobility of 1-50 cm^2/Vs for few-layer MoS2[1, 2]. However, greatly increased mobility - as high as 900 cm^2/Vs - was recently reported for monolayer MoS2 by Radisavljevic, et al.[Ref. 3; see also Refs. 4-6], and for multilayer MoS2 by others[7, 8], in devices covered by a high-kappa dielectric layer and a metal top gate. Similar increases were reported for electrolyte top-gated MoS2[9]. A puzzling common aspect of these reports is that the double-gated devices consistently show much higher mobility when measured using the weakly-coupled back gate (typically 300 nm of SiO2) than using the strongly-coupled top gate. While this difference might be attributed to a different quality of the top and bottom surfaces, the large discrepancy motivates close examination of the measurement techniques to rule out spurious effects. Notably, it has been shown that the mobility may be greatly overestimated in this geometry[10, 11]. There is good evidence that this is the case here[4-9]; below we discuss Radisavljevic, et al.[4] as an illustrative example.
