The main supportive therapy in acute respiratory distress syndrome patients is mechanical ventilation. As with any therapy, mechanical ventilation has side-effects, and may induce lung injury (ventilator-induced lung injury (VILI)/ventilator-associated lung injury). The mechanical factors responsible for VILI are thought to be related to tidal recruitment/derecruitment of previously collapsed a...

an experiment was conducted to determine the optimal level of supplemental lysine in a corn-soybean mealcottonseed meal starter diet. three hundred and sixty day-old male chicks (ross 308) were used in a completely randomized design (15 birds per each pen). a basal diet was formulated to meet or exceed nrc (1994) recommendations except for lysine. graded levels of supplemental lysine (0, 0.1, 0...

soil quality is a necessary indicator of land management. different indices are applied to evaluate farming systems, soil types and land uses based on soil quality. the slope of retention curve at its inflection point has been defined as soil physical quality index (si) but the relationships between si and penetration resistance (pr), the least limiting water range (llwr), and available water c...

The linear phenomenological equations of nonequilibrium thermodynamics are limited theoretically to near equilibrium although a number of biological systems have been shown to exhibit a "linear" relationship between steady-state flows and conjugate thermodynamic forces outside the range of equilibrium. We have found a multidimensional inflection point which can exist well outside the range of e...

The log-aesthetic curves include the logarithmic (equiangular) spiral, clothoid, and involute curves. Although most of them are expressed only by an integral form of the tangent vector, it is possible to interactively generate and deform them and they are expected to be utilized for practical use of industrial and graphical design. However, their input method proposed so far by use of three soc...

OBJECTIVE To evaluate a new technique for pressure-volume curve tracing. DESIGN Prospective experimental study. SETTING Animal research laboratory. SUBJECTS Six anesthetized rats. INTERVENTIONS Two pressure-volume curves were obtained by means of the super-syringe method (gold standard) and the continuous positive airway pressure (CPAP) method. For the CPAP method, the ventilator was sw...

1 Ana Aizcorbe In the mid-1990s, measured productivity growth for the semiconductor industry showed a pickup that coincided with an economy-wide acceleration in labor productivity growth. This pickup in semiconductor markets stems from an increase in the growth of real output that was, in turn, generated by what Dale Jorgenson (2001) called an " inflection point " in the price indexes for the s...

Gompertz growth functions were fitted to longitudinal measurements of daily feed intake (DFI) and BW of 586 boars and 495 gilts from a selection experiment in Yorkshire pigs for residual feed intake (RFI). The selection experiment consists of a line selected for low residual feed intake (LRFI) for 5 generations and a randomly selected control line (CTRL). The objectives of this study were to us...

OBJECTIVE To investigate the correlation between different radiographic methods in the evaluation of the lumbosacral concavity. METHODS The sample consisted of 52 individuals with ages ranging from 18 to 28 years old. The procedures related to radiographic image collection were carried out in collaboration with a diagnostic imaging center of a hospital in Curitiba, PR, Brazil. The angles of t...
