A multiresidue method has been developed for quantification and identification of 66 multiclass priority organic pollutants in water by fast gas chromatography (GC) coupled to mass spectrometry (MS). Capabilities and limitations of single quadrupole mass spectrometer as detector in fast GC were studied evaluating the chromatographic responses in terms of sensitivity and chromatographic peak sha...

Tumours of the perianal region occur frequently in dogs (Bennett et al. 2002), with benign adenomas comprising 5896% of tumours at this site (Turek & Withrow 2013). In some cases these may transform to become malignant perianal adenocarcinomas, and these need to be distinguished from adenocarcinomas which derive from the apocrine secretory epithelium within the wall of the anal sacs (Polton & B...

There is a growing interest in utilizing in situ-generated dimethyldioxirane (DMDO) as an oxidant for synthetic purposes and bleaching and decontamination applications, but the ability to quantify the organic cyclic peroxide species is often complicated by the presence of other reactive components, peroxymonosulfate and acetone, within the solution matrix. This paper is the first to report the ...

Approximately 11% and 25% of annual Canadian oil spill accidents are gasoline and diesel spills, respectively. Gasoline and diesel spills are a challenge to conventional environmental forensic techniques because refinery processes remove most of the higher molecular weight biomarkers. This study presents a tiered environmental forensics strategy that includes such information as site operationa...

In semiconductor spintronics, electron spin rather than charge is the key property. This paper describes several spin-related devices using spin-orbit interaction. We have experimentally confirmed that the spin-orbit interaction in a semiconductor two-dimensional electron gas channel can be controlled by a gate voltage. This is the first step towards the creation of functional spin devices. The...

NTT has been successfully operating its experimental network GEMnet (Global Enhanced Multifunctional Network) for research and development of global information-sharing services since 1998. To adapt to new requirements in the business environment and technical advances, we have formulated a new testbed concept, GEMnet2, and begun construction. Its three key aims are to let us test technologies ...
