We give here some of the basic properties of the classes ¡4>^|, {♦ !, 1 < r < 1, of dilation operators acting in rearrangement-invariant spaces I on the circle It is shown that to each space 3E there correspond two numbers i, V, called indices, which satisfy 0 < r¡ < g < 1; these numbers represent the rate of growth or decay of ||* || as r — + 1. By using the operators + to obtain estimates for...

Chronic obstructive pulmonary disease (COPD) is characterised by high morbidity and mortality. It remains unknown which aspect of lung function carries the most prognostic information and if simple spirometry is sufficient. Survival was assessed in COPD outpatients whose data had been added prospectively to a clinical audit database from the point of first full lung function testing including s...

effectiveness of military is function of training system effectiveness. notice to training system and knowledge about effectiveness and efficiency is one of the important functions of top military leaders. goal of this study is achieving a performance appraisal model for measuring effectiveness and efficiency of military university training system. for achieving this goal, we design two main qu...

Spectral analysis of heart rate variability (HRV) is useful as a noninvasive means of assessing autonomic function in patients with obstructive sleep apnea (OSA). However, standard spectral measures, such as the ratio of low-frequency to high-frequency power (LHR) and normalized high-frequency power (NHFP), can be confounded by the abnormal breathing patterns that occur during sleep. To circumv...

INTRODUCTION In chronic kidney disease (CKD) patients left ventricular (LV) diastolic dysfunction occurs frequently and is associated with heart failure (HF) and higher mortality. Left ventricular systolic dysfunction is associated with coronary artery disease (CAD) and is a major determinant of prognosis. The aim of this study was to assess indices of LV diastolic dysfunction in CKD patients. ...

The influence of age on six Doppler echocardiographic indices of left ventricular diastolic function was assessed in 86 normal volunteers aged from 20 to 74 years (mean 36). Five of the six indices showed a linear relation with age. Duration of isovolumic relaxation and maximal late diastolic (atrial) flow velocity increased significantly with age (r = 0-34 and r = 0-69, respectively). Converse...

Introduction: We investigated the difference in left ventricular ejection fraction (LVEF) and end-systolic volume(ESV) measured by gated myocardial perfusion SPECT (GSPECT) in the post-dipyridamole stress and rest periods, and compared the results with the perfusion patterns found in the conventional non-gated tomograms. Methods: 297 consecutive patients were studied with post-stress and rest T...

to test the effect of culling herd life from the breeding goal function, 4 different selection indices were established as: index 1: using milk production (milk), fat percentage of milk (fat%) and rear udder height (ruh); index 2: using milk , fat% and fore teat placement (ftp), index 3: using milk, fat% and fore udder attachment (fua); and index 4: using milk, fat%, ruh, ftp and fua) under two...
