5. Some caveats -The phonetics/phonology interface is a broad topic that has been considered from many points of views. -Extensive recent literature in acquisition, psycholinguistics, role of the lexicon, role of speech perception (See among others, recent LabPhon volumes, Burton-Roberts et al. 2000, Hume and Johnson 2001, Bod et al. 2003) -Conclusion recently argued for by Pierrehumbert (2003,...

We report a systematic investigation about the mechanism of pH sensing using SnO2 nanobelt field effect transistors (FETs). The FETs, based on single SnO2 nanobelts, are channel-limited and with proper contact passivation; the pH sensing was conducted with sodium phosphate solutions through integrated microfluidics. The responses of the FET channel conductance to pH were measured at different g...

The paper examines the potential of waste stabilisation ponds to provide water for reuse in extreme continental climates such as those of central Asia, where precipitation is low and summer evaporation rates are high. A simple model is used to predict water availability, BOD and faecal coliform removal for different configurations and operating regimes. The results show a significant proportion...

Bioassay-guided isolation of the stems of Gelsemium elegans has led to the isolation of two new Gelsemium alkaloids, 21-(2-oxopropyl)-koumine (1) and 11-methoxygelselegine (2), and two known alkaloids, koumine (3) and gelselegine (4). The structures of 1-2 were determined by spectroscopic (for both) and single-crystal X-ray diffraction (for 1) analysis. All compounds isolated were evaluated for...

The classical MOSFET is reaching its scaling limits and “endof-roadmap” alternative devices are being investigated. Amongst the different types of SOI devices proposed, one clearly stands out: the multigate fieldeffect transistor (multigate FET). This device has a general “wire-like” shape. Multigate FETs are commonly referred to as “multi(ple)-gate transistors”, “FinFETs”, “tri(ple)-gate trans...

The steep sub-threshold characteristics of inter-band tunneling FETs (TFETs) make an attractive choice for low voltage operations. In this work, we propose a hybrid TFETCMOS chip multiprocessor (CMP) that uses CMOS cores for higher voltages and TFETs for lower voltages by exploiting differences in application characteristics. Building from the device characterization to design and simulation of...

Ozonation was investigated as a potential post-treatment step for biologically treated landfill leachate to enhance the biodegradability and observe the influence of the initial organic matter concentration and pH. Changes in COD, UV absorption at 254 nm (UVA254) and BOD content were measured during and after ozonation, and the ozone utilisation efficiency at different conditions was calculated...

Interest in biosensors based on field-effect transistors (FETs), where an electrically operated gate controls the flow of charge through a semiconducting channel, is driven by the prospect of integrating biodetection capabilities into existing semiconductor technology. In a number of proposed FET biosensors, surface interactions with biomolecules in solution affect the operation of the gate or ...

A new phenacene-type molecule with five fused aromatic rings was synthesized: 2,7-didodecylphenanthro[2,1-b:7,8-b']dithiophene ((C12H25)2-i-PDT), with two terminal thiophene rings. Field-effect transistors (FETs) using thin films of this molecule were fabricated using various gate dielectrics, showing p-channel normally-off FET properties with field-effect mobilities (μ) greater than 1 cm2 V-1 ...

Onsite sanitation with septic tanks is popular in most of the Asian countries. The case study conducted in Hanoi and suburban area of Bangkok indicates that the septic tanks employed did not perform as required. The septic tanks just convert the suspended pollutants into dissolved form and release them to the environment due to insufficient maintenance. Thus the effluent from the septic tank is...
