background: the coronary artery bypass grafting (cabg) is performed to completely or partially relieve the symptoms of coronary heart disease (chd). one of the most important goals of this operation is the improvement of quality of life (qol). the data obtained on healthrelated quality of life (hrqol) represents the functional limitations and the alleviation of symptoms among patients. many fac...

Recently, there has been some discussion of whether it is possible to score highly in one dimension of physical activity behaviour (e.g., moderate intensity exercise) whilst also scoring poorly in another (e.g., sedentary time). Interestingly, direct empirical observations to support these proposals are lacking. New technologies now enable the capture of physical activity thermogenesis on a min...

We explore in depth the theory behind deterministic fractals by investigat­ ing transformations on metric spaces and the contraction mapping theorem. In doing so we introduce the notion of the Hausdorff distance metric and its connection to the space of fractals. In order to understand how deterministic fractals are generated, we develop the concept of an iterated function system (IFS) and what...

We consider the effects of a velocity-independent friction force on cantilever damping. It is shown that this dissipation mechanism causes nonlinear effects in the cantilever vibrations. The size of the nonlinear-ity increases with decreasing cantilever velocity. Our analysis makes it possible to understand Stipe's et al. [1] experiments where an amplitude dependence of the cantilever eigenfreq...

INTRODUCTION There are no studies that enable to explore the impact that might have the scoring of the importance that children assign to each dimension that encompass the assessment of their quality of life (QoL). OBJECTIVE To analyze the influence of the importance assigned by children to the different spheres of their lives when having to assess their quality of life. MATERIAL AND METHOD...

In this paper, we estimate the dimension of a global attractor for a nonclassical hyperbolic equation with a viscoelastic damping term in Hilbert spaces H2 0 × L2 and D(A) × H2 0 , where D(A) = {v ∈ H2 0 | Av ∈ L2} and A = ∆2. We obtain an explicit formula of the upper bound of the dimension of the attractor. The obtained dimension decreases as damping grows and is uniformly bounded for large d...

The objects of study are Banach spaces L of continuous real-valued functions on a compact Hausdorff space Q, containing constants and separating points. If the intersection of an arbitrary family of M-ideals in L is an M-ideal then, in certain specified circumstances, it is shown that L is necessarily equal to CR(Q); these results extend a well-known theorem of Gleit [9]. An intrinsic character...

Generalizing Duality Theorem of V. V. Fedorchuk [11], we prove Stone-type duality theorems for the following four categories: all of them have as objects the locally compact Hausdorff spaces, and their morphisms are, respectively, the continuous skeletal maps, the quasi-open perfect maps, the open maps, the open perfect maps. In particular, a Stone-type duality theorem for the category of all c...
