OBJECTIVES This study evaluates whether a low preoperative quality of life (QoL), measured with the EuroQoL instruments EQ-5D and EQ-visual analogue scale (VAS) can be used as a predictor of mortality after elective isolated myocardial revascularization. METHODS A total of 2501 patients, with a mean age of 65.3 ± 9.4 (range 18-93) years and a mean additive EuroSCORE of 2.7 ± 2.1 (0-12), under...

Kennedy et al. have introduced mixtures of monoor polyfunctional aralkyl chlorides with BCl, as initiating systems for the polymerization of isobutene'). This so-called inifer technique has been demonstrated to be a valuable method for the production of telechelic polymers2). The mechanism of initiation, which has been suggested for these polymerizations'*2), is in full agreement with the resul...

This paper represents the third step in the development of EQ-logics. Namely, after developing propositional and higher-order EQ-logics, we focus also on predicate one. First, we give a brief overview of the propositional EQ-logic and then develop syntax and semantics of predicate EQ-logic. Finally, we prove completeness by constructing a model of a consistent theory of EQ-logic from the syntac...

A special algebra called EQ-algebra has been recently introduced by Vilém Novák. Its original motivation comes from fuzzy type theory, in which the main connective is fuzzy equality. EQ-algebras have three binary operations meet, multiplication, fuzzy equality and a unit element. They open the door to an alternative development of fuzzy (manyvalued) logic with the basic connective being fuzzy e...

background β-thalassemia is a prevalent genetic disease in mediterranean countries. the most common treatments for this disease are blood transfusion plus iron chelation (btic) therapy and bone marrow transplantation (bmt). patients using these procedures experience different health-related quality of life (hrqol). the purpose of the present study was to measure hrqol in these patients using 2...

background: the purpose of this research was to determine the traffic noise level and changes in the kerman city, southeast iran in recent years. methods: this cross-sectional study was carried out in 2008 to investigate the existing noise situation in kerman. sound levels (l max , l min , l eq , l 99 , l 90 , l 50 and l 10 ) were determined throughout 13 stations using sound level measurement ...

Ethoxyquin phosphate (EQ-P) and ethoxyquin hydrochloride (EQ-HCl) were synthesized and studied for genotoxic and antioxidant activities with the use of comet assay and micronucleus test performed on human lymphocytes. The results were compared with the activities of the earlier studied ethoxyquin (EQ; 1,2-dihydro-6-ethoxy-2,2,4-trimethylquinoline), a strong antioxidant used mainly as a preserva...

1. Introduction Recall that a fuzzy equivalence relation in a nonempty set S is a fuzzy relation eq : S×S → [0,1] such that eq(x,x) = 1 (reflexive); eq(x,y) = eq(y,x) (symmetric) ; eq(x,y)≈eq(y,z) ≤ eq(x,z) (≈-transitive) where ≈ is a t-norm. Now, as observed by De Cock and Kerre in [3], this notion is not suitable to model approximate equality and therefore to solve paradoxes like the so calle...

Background β-Thalassemia is a prevalent genetic disease in Mediterranean countries. The most common treatments for this disease are blood transfusion plus iron chelation (BTIC) therapy and bone marrow transplantation (BMT). Patients using these procedures experience different health-related quality of life (HRQoL). The purpose of the present study was to measure HRQoL in these patients using 2 ...
