METHOD FOR THE PREDICTION OF THE DEVELOPMENT OF CHRONIC PULMONARY HEART IN COAL WORKERS WITH CHRONIC OBSTRUCTIVE PULMONARY DISEASE

452 miners at the age of40-55years (average age is 50,9 ± 0,2 years) with chronic obstructive pulmonary disease were studied. Chronic pulmonary heart was detected in 289 patients (63,9 %). Using Bayes' method based on the determination of prognostic factors we have elaborated the technique for the prediction of the development of chronic pulmonary heart in miners with chronic obstructive pulmonary disease. The technique is based on the presence of respiratory insufficiency, associated ischemic heart disease and arterial hypertension, blood groups by AB0, MN, and P systems, some structural and functional indicators of heart (a myocardium mass index of aortic ventricle heart, an index of relative thickness of walls of aortic ventricle heart, an index of sphericity of aortic ventricle heart and an average pressure in a pulmonary artery). The use of genetic markers of blood groups by AB0, MN, and P systems allows more detailed estimate genetic predisposition to disease. By increasing the number of analyzed factors influencing the development of chronic pulmonary heart and using of additional markers, we have more accurate prediction of this complication. All figures are reduced in the general prognostic table. The work with the table is the following, it is necessary to sum up all the prognostic coefficients taking into account a sign. At the value of total amount of+6 points or more predisposition to development of chronic pulmonary heart for a worker is more predicted, at the sum less than -6 points we predict the resistance to development of chronic pulmonary heart, at intermediate values the forecast is not defined. The main advantage of the technique is speed and minor material costs. So, while conducting a single assessment of the health of miners with chronic obstructive pulmonary disease in outpatient and polyclinic conditions it is simply to select a group of persons at high risk of developing chronic pulmonary heart for timely preventive actions

THE INFLUENCE OF CONCOMITANT CARDIOVASCULAR PATHOLOGY (ISCHEMIC HEART DISEASE AND ARTERIAL HYPERTENSION) ON THE CHANGES OF RIGHT VENTRICLE OF HEART IN MINERS WITH CHRONIC OBSTRUCTIVE PULMONARY DISEASE

Associated cardiovascular pathology (ischemic heart disease and arterial hypertension.) in miners with chronic obstructive pulmonary disease increases the degree of hypertrophy of myocardium of right ventricle of heart and worsens its systolic and diastolic functions

DISTRIBUTION OF BIOCHEMICAL AND MOLECULAR-GENETIC MARKERS OF GENES IN WORKERS OF COAL MINING ENTERPRISES OF KUZBASS REGION SUFFERING FROM CHRONIC DUST BRONCHITIS

Distribution of genotypes of biochemical markers of HP, GC, EsD, АсР genes, genotypes on polymorphic variants of the genes coding enzymes of biotransformation GSTT1 (GST-ɵ1) and GSTM1 (GST-μ1) and NOS3 (VNTR4 polymorphism) in the miners with chronic mechanic bronchitis, and in persons without this occupational pathology is investigated. It is shown that the owners of EsD 1-2, АсР bb genotypes are most subject to development of chronic mechanic bronchitis. Endogen factors of resistance to this disease are GC 1-1, EsD 1-1, АсР bc genotypes

Intercalibration of the barrel electromagnetic calorimeter of the CMS experiment at start-up

Calibration of the relative response of the individual channels of the barrel electromagnetic calorimeter of the CMS detector was accomplished, before installation, with cosmic ray muons and test beams. One fourth of the calorimeter was exposed to a beam of high energy electrons and the relative calibration of the channels, the intercalibration, was found to be reproducible to a precision of about 0.3%. Additionally, data were collected with cosmic rays for the entire ECAL barrel during the commissioning phase. By comparing the intercalibration constants obtained with the electron beam data with those from the cosmic ray data, it is demonstrated that the latter provide an intercalibration precision of 1.5% over most of the barrel ECAL. The best intercalibration precision is expected to come from the analysis of events collected in situ during the LHC operation. Using data collected with both electrons and pion beams, several aspects of the intercalibration procedures based on electrons or neutral pions were investigated

An RPC-based Technical Trigger for the CMS Experiment

In the CMS experiment, sub-detectors may send special trigger signals, called "Technical Triggers", for special purposes like test and calibration. The Resistive Plate Chambers are part of the Muon Trigger System of the experiment, but might also produce a cosmic muon trigger as Technical Trigger to be used during the commissioning to the detectors, the CMS magnet Test Cosmic Challenge and the later running of CMS. The proposed implementation is based on the development of a new board, the RBC Balcony Collector (RBC); the test results on prototypes and their performance during the recent CMS Cosmic Challenge are presented

First measurements of the performance of the Barrel RPC system in CMS

During the summer 2006, a first integrated test of a part of the CMS experiment was performed at CERN collecting a data sample of several millions of cosmic rays events. A fraction of the Resistive Plate Chambers system was successfully operated. Results on the RPC performance are reported

Random telegraph noise in the photoluminescence of individual GaxIn1-xAs quantum dots in GaAs

We have investigated random telegraph noise in the photoluminescence from InGaAs quantum dots in GaAs. Dots switching among two and three levels have been measured. The experiments show that the switching InGaAs dots behave very similarly to switching InP dots in GaInP. but differently from the more commonly investigated colloidal dots. The switching is attributed to defects, and we show that the switching can be used as a monitor of the defect

Random telegraph noise in the photon emission from semiconductor quantum dots

This study has observed and investigated random telegraph noise in the photoluminescence from InAs quantum dots in GaAs and InP quantum dots in GaInP. The dots are grown by the Stranski-Krastanow technique with a sufficiently low surface density that individual dots easily could be investigated. The luminescence from many single quantum dots, exhibiting switching between two levels, has been spectrally resolved as a function of time. The random telegraph noise is only observed in the presence of band filling. Results show no spectral shift of the emission in the different states. It is only the intensity, mainly for higher energy peaks that changes. The InAs quantum dots behave very similarly to InP/GaInP and InGaAs/GaAs quantum dots with respect to random telegraph noise. The similarities between the different systems argue for a common mechanism behind the blinking. Experiments are performed where the switching behaviour is changed in all the different systems supporting the idea that non-radiative defects are responsibl
