OBJECTIVES To describe the thickness of mesorectal fat in local Chinese population and its impact on rectal cancer staging. DESIGN Case series. SETTING Two local regional hospitals in Hong Kong. PATIENTS Consecutive patients referred for multidisciplinary board meetings from January to October 2012 were selected. MAIN OUTCOME MEASURES Reports of cases that had undergone staging magnetic...

BACKGROUND Endotracheal tube (ETT) cuffs create a seal to protect against secretion entry to the lungs. Cuff inflation currently is recommended at 20-30 cm H2O pressure. ETT designs have variable seal performance in bench studies using rigid tracheal models lacking the dynamic characteristics of the human trachea. We compared ETT designs within a new, biorealistic tracheal model to assess cuff ...

We report the observation of atomic-pair absorption in barium and in barium-thallium vapors using a white-light source. At atomic densities on the order of 10(17) atoms/cm(3) we measure absorptions of 2.9% cm(-1) for Ba-Ba and 2.3% cm(-1) for Ba-TI. In both cases, the absorption maxima occur at the predicted (R = infinity) wavelength and have a full width at half maximum of approximately 15 cm(...

Bolinder, M. A., Angers, D. A., Bélanger, G., Michaud, R. et Laverdière, M. R. 2002. Root biomass and shoot to root ratios of perennial forage crops in eastern Canada. Can. J. Plant Sci. 82: 731–737. Shoot to root ratios (S:R) at peak standing crop are commonly used to estimate the annual crop residue C inputs to the soil from the root biomass left in the soil at harvest. However, root biomass ...

CM: Problem Management is a detailed problem management process model to be utilised within corrective maintenance. It has been developed at ABB and evaluated for its industrial relevance within 17 non-ABB organisations. In this paper, we present the evaluation results of CM: Problem Management. Our primary goal is to confirm its industrial relevance. Our secondary goal is to establish current ...

Gain length products up to gl w 14 for the J = 0-1 line of Ne-like Ar at 46.9 nm have been achieved in 15-cmlong plasma columns generated by a fast capillary discharge. Amplification in plasma columns up to 20 cm in length was investigated. The laser line intensity is observed to increase exponentially for plasma lengths of up to 15 cm, above which it is observed to saturate. The saturation beh...
