A microbiological survey was undertaken on the eight patients in the Liverpool District who have a humidifier attachment on their oxygen concentrator. All but one of the humidifiers were contaminated with potentially pathogenic bacteria.

We present 0.1–10 keV observations of HerX-1 obtained with the Low-Energy Spectrometer Concentrator instrument onboard the BeppoSAX satellite during the main on-state of the 35 day cycle. We confirm the existence of an intense 0.093 keV blackbody component and a broad emission feature at 0.94 keV. The pulse phase dependence of these components is similar, suggesting a common origin. This is mos...

A development aid project to Malawi is described. This involved the development of a suitable anaesthetic machine for use in under-developed countries and the selection of a suitable oxygen concentrator to provide it with air and oxygen. All government hospitals were provided with anaesthetic equipment and personnel were trained to keep it regularly serviced. Follow up testing of reliability wa...

The main goal of this work is to propose a way for combined use of two nontraditional algorithms by solving topological problems on telecommunications concentrator networks. The algorithms suggested are the Simulated Annealing algorithm and the Genetic Algorithm. The Algorithm of Simulated Annealing unifies the well known local search algorithms. In addition Simulated Annealing allows acceptati...

This paper describes a mesh networking based solution on Routing Protocol for Low power and Lossy network to realize Automated Metering Infrastructure (AMI) network communication. Automated Metering Infrastructure is expected to facilitate the transport of meter readings from meters to the utility provider and control information in the other direction. The smart meters send the meter data to t...

1/f noise is one of the main noise sources of giant magnetoresistance (GMR) sensors, which will cause intrinsic detection limit at low frequency. To suppress this noise,a novel vertical motion modulated flux concentrator (VMMFC) is proposed in this paper, which has high efficiency and simple structure. The flux concentrator and modulation film of VMMFC were analyzed with numerical simulation. T...

This paper presents the fault detection technique in wide area power system network using Phasor Data Concentrator (PDC). Single line to ground (SLG) fault data of transmission line is processed using the WAMS technology. Phasor Data Concentrator (PDC) is primarily data collecting centres located at the control centre processing unit and is responsible for collecting all the PMUs data that is t...

Innovative microfluidic technology has enabled massively parallelized and extremely efficient biological and clinical assays. Many biological applications developed and executed with traditional bulk processing techniques have been translated and streamlined through microfluidic processing with the notable exception of sample volume reduction or centrifugation, one of the most widely utilized p...
