Thermochromism in yttrium iron garnet compounds.

Polycrystalline yttrium iron garnet (Y3Fe5O12, hereafter labeled YIG) has been synthesized by solid-state reaction, characterized by X-ray diffraction, Mössbauer spectroscopy, and UV-vis-NIR diffuse reflectance spectroscopy, and its optical properties from room temperature (RT) to 300 °C are discussed. Namely, its greenish color at RT is assigned to an O(2-) → Fe(3+) ligand-to-metal charge transfer at 2.57 eV coupled with d-d transitions peaking at 1.

A systems model of training for patients in phase 2 cardiac rehabilitation.

Background: The aim of this study was to apply a systems model of training for athletes in patients with coronary artery disease (CAD) undergoing phase 2 cardiac rehabilitation.

Methods: Data from six patients with CAD undergoing 20 conventional training sessions were used to test this model. The method required daily training quantification using heart rate, and regular assessment of real exercise tolerance using a constant-duration test.

Applying a systems model of training to a patient with coronary artery disease.

Purpose: The aim of the present study was to apply a systems model of training for athletes to a patient with coronary artery disease (CAD) undergoing phase 3 rehabilitation.

Methods: A patient with CAD underwent 14 wk of training during which exercise was quantified using intensity and duration. Real exercise tolerance was assessed twice a week during this period using a constant-load test.

Dose-dependent effect of individualized respiratory muscle training in children with Duchenne muscular dystrophy.

The aim of this study was to evaluate the effects of low intensity, home inspiratory muscle training on respiratory muscle endurance in children with Duchenne muscular dystrophy, using a double-blind protocol. The originality aspect of this study is the use of a reproducible method of endurance and of the same method for evaluation and training. We studied eight trained children (mean age 14.
