The forcing construction Pmax, invented by W. Hugh Woodin, produces a model whose collection of subsets of ω1 is in some sense maximal. In this paper we study the Boolean algebra induced by the nonstationary ideal on ω1 in this model. Among other things we show that the induced quotient does not have a simply definable form. We also prove several results about saturation properties of the ideal...

Fast muscle fibres were isolated from abdominal myotomes of Atlantic cod (Gadus morhua L.) ranging in size from 10 to 63 cm standard length (Ls). Muscle fibres were subjected to sinusoidal length changes about their resting length (Lf) and stimulated at a selected phase of the strain cycle. The work performed in each oscillatory cycle was calculated from plots offeree against muscle length, the...

This cross-sectional study compared somatic, endurance performance determinants and heart rate variability (HRV) profiles of professional soccer players divided into different age groups: GI (17-19.9 years; n = 23), GII (20-24.9 years; n = 45), GIII (25-29.9 years; n = 30), and GIV (30-39 years; n = 26). Players underwent somatic and HRV assessment and maximal exercise testing. HRV was analyzed...

Granulomatous involvement of skeletal muscle occurs in 50 to 80 percent of patients with sarcoidosis. How this may affect respiratory muscle function in sarcoidosis is not known. To attempt to answer this question, we compared respiratory function and muscle force generation, and control of ventilation in 12 untreated patients with 12 healthy, nonsmoking subjects. While seated, room air breathi...

BACKGROUND Right ventricular (RV) function is a major determinant of outcome in pulmonary arterial hypertension (PAH). However, uncertainty persists about the optimal method of evaluation. METHODS We measured RV end-systolic and end-diastolic volumes (ESV and EDV) using cardiac magnetic resonance imaging and RV pressures during right heart catheterization in 140 incident PAH patients and 22 c...

Effects of climatic changes in transitional ecosystems are often not linear, with some areas likely experiencing faster or more intense responses, which something important to consider the perspective climate forecasting. In this study Venice lagoon, time series past decade were used, and primary productivity was estimated from hourly oxygen data using a published model. Temporal spatial patter...

Sr2FeMoO6–δ single-phase samples without Fe/Mo cations superstructural ordering (P) and with Curie temperature 407 K were obtained by the solid-phase technique. According to XRD data, growth dynamics of parameter P is nonlinear. In this case, process reaching maximum values (Pmax) long its rate several times lower than change oxygen index 6–δ. It was found that increasing isothermal annealing, ...
