The power management of ICT systems, that is, data processing (Dp) and telecommunication (Tlc) systems, is becoming a relevant problem in economical terms. Dp systems totalize millions of servers and associated subsystems (processors, monitors, storage devices, etc.) all over the world that need to be electrically powered. Dp systems are also used in the government of Tlc systems, which, beside...

an asthmatic attack. Eighteen patients were studied during 20 separate asthmatic attacks. The patients behaved in one of three ways with regard to total lung capacity (TLC): group I had an elevated TLC during the acute asthmatic attack which returned to normal, group II had a normal TLC throughout the attack, and group III had an elevated TLC that did not return to normal on recovery from the a...

We adapted the reagents from 11 different enzyme-multipled immunoassay technique (EMrr; Syva Co., Palo Alto, CA 94304) drug-detection kits for use in a centrifugal analyzer. The antibody reagents were mixed into a single dilute solution, and the enzyme-labeled drug derivatives were combined similarly (Mixed EMIT reagents), for use in testing urine samples for the presence of multiple drugs. The...

A new method for on-spot detection and characterization of organic compounds resolved on thin layer chromatography (TLC) plates has been proposed. This method combines TLC with dielectric barrier discharge ionization (DBDI), which produces stable low-temperature plasma. At first, the compounds were separated on TLC plates and then their mass spectra were directly obtained with no additional sam...

RATIONALE In clinical trials, homogeneous emphysema patients have responded well to upper lobe volume reduction but not lower lobe volume reduction. MATERIALS/METHODS To understand the physiological basis for this observation, a computer model was developed to simulate the effects of upper and lower lobe lung volume reduction on RV/TLC and lung recoil in homogeneous emphysema. RESULTS Patie...

BACKGROUND The aims of this study are to investigate the difference between the diaphragm thickness at end expiration and the thickness at total lung capacity (TLC), and to examine differences in inspiratory muscle function between stroke patients and healthy individuals. MATERIAL AND METHODS Forty-five stroke patients and 49 healthy volunteers were included in this study. Diaphragm thickness w...

PURPOSE Lung size mismatch is a major cause of poor lung function and worse survival after lung transplantation (LTx). We compared predicted total lung capacity (pTLC) and TLC measured by chest computed tomography (TLC(CT)) in LTx candidates. MATERIALS AND METHODS We reviewed the medical records of patients on waiting lists for LTx. According to the results of pulmonary function tests, patien...

Radioimmunoassay (RIA) and thin-layer chromatography (TLC) were compared for morphine detection in an actual narcotic clinic setting. A choice of urines from all those screened by TLC allowed a critical comparison as to actual use or non-use of narcotic drugs, rather than a sampling at random in which the question of possible false positives or negatives cannot be conclusively answered. Althoug...

Thin-layer chromatography (TLC) has been a useful tool in the analysis of numerous urinary constituents; as in most applications of adsorption TLC, it is best used in conjunction with other chromatographic processes. The application of TLC to the resolution of polar urinary products derived from lipids is shown for the metabolism of a 14C-labeled fatty acid and a 14C-labeled glyceryl thioether....
