The isotope ratio mass spectrometer Dual inlet double collector gas isotope ratio mass spectrometers by inherent design, possess a low resolving power but extremely high sensitivity. These specialized instruments are capable of precise estimates of the heavy isotopic content of pure, low molecular weight permanent gases such as H,, CO,, N, and SO,. For present purposes, consideration will be gi...

This paper describes the MQNA Markovian Queueing Networks Analyser, a software tool to model and obtain the stationary solution of a large class of Queueing Networks. MQNA can directly solve open and closed product-form queueing networks using classical algorithms. For finite capacity queueing models, MQNA generates Markovian description in the Stochastic Automata Networks (SAN) and Stochastic ...

WAMPA (for Wide Area MicroProbe Analyser) represents a new scientific instrument concept for planetary exploration. WAMPA builds on recently published research such as sensor webs and distributed microsensors [1][2] but adds new sensor and localisation concepts. WAMPA is driven by the recurrent theme in spacecraft and sensor design to achieve smaller, lighter and lower cost systems. The essenti...

Scientific research is increasingly dependent on publicly available information and data sharing. So far, the best practices to ensure that data is accessible and shareable has been to deposit it in public repositories. However, these repositories often fail to implement mechanisms that measure data quality, which could lead to improving the discoverability of existing data, and contribute to i...

In CT-based security screening, a challenging problem is to correctly identify and label objects in a scene from X-ray projection data. The presence of artifacts in the reconstructed image confounds traditional segmentation and labeling methods. In this work, we focus on integrating machine learning, physical modeling and Bayesian inference in a framework for direct material identifi cation and...

PURPOSE Validity of the 20-meter multi stage shuttle run test (20-m MST) has not been studied in Nepalese population. The purpose of this study was to validate the applicability of the 20-m MST in Nepalese adult females. METHODS Forty female college students (age range, 20.42 ~24.75 years) from different colleges of Nepal were recruited for the study. Direct estimation of VO(2) max comprised ...

16 October 2007 ■ MLO www.mlo-online.com T he significance of good practice during the pre-testing phase of clinical-laboratory investigation cannot be overemphasized. The production of high-quality, accurate results, which are clinically useful, depends as much on practice before the patient’s sample reaches the laboratory as it does on the analytical phase within the laboratory. There are few...

Point-of Care analysis is increasingly being applied in the prehospital scene. Arterial blood gas analysis is one of many new initiatives adding to the diagnostic tools of the prehospital physician. In this paper we present a study on the feasibility of the Radiometer ABL-90 in a ground-based Mobile Emergency Care Unit and report on some clinical situations in which the apparatus has proven ben...

can be obtained. The technique is essentially a graphic one in which the function f(x) and its derivatives /' (x), /" (x), ■ ■ ■ are generated by an electronic differential analyser The method depends heavily on the ability of the analyser to produce an accurate plot of the function and its derivatives. The use of these accurate graphs is obvious for finding the real roots of the equation. But ...
