The gas turbine engine is finding progressively more acceptance in different applications with different operation and performance requirements.
In this work, a model free power gas turbine engine, driving an electric dynamometer, is run in two modes, namely, a single and two-shaft operation using LPG as fuel. Experimental readings under controlled operating conditions and relevant calibration curves were used to calculate performance, including net power output, specific fuel consumption and engine thermal efficiency.
Results show that operating a two-shaft engine in the single-shaft mode would boost the part load power tremendously. However, the torque characteristic of the two-shaft mode at part load is superior.
A polyclonal antiserum to ubiquitin, a low molecular weight protein involved in the ATP-dependent removal of abnormal cytoplasmic proteins, has been used to stain spinal cord from 10 cases of motor neurone disease and from 12 control spinal cords. All 10 cases of motor neurone disease exhibited antiubiquitin-immunoreactive deposits in a proportion of the surviving anterior horn cells but these deposits were not seen in any of the 12 controls. These ubiquitin deposits do not correspond to previously described neuronal inclusions in motor neurone disease. The ubiquitin deposits represent, therefore, a new neuronal Basket Blazer Nike Pas Cher inclusion which Blazer Nike Femme Courir possibly reflects previously unrecognised degradative events occurring in the vulnerable neurones.
The literature on container port efficiency has typically centered on ports in advanced markets or comparisons within regions. This study compares the efficiency of port operations in emerging markets (BRIC and the Next-11) with the more advanced markets (G7). We use data envelopment analysis to evaluate the container ports based on the import and export cargo volumes in 2005. Our results suggest that none of the ports in the advanced markets are role models for the field. Chaussure Nike Blazer This study provides a first step towards gaining insights into port efficiency in emerging markets.
