Introduction: Functional residual capacity (FRC) measurement is now available on new ventilators as an automated procedure. We compared FRC, static thoraco-pulmonary compliance (Crs) and PaO2 evolution in an experimental model of acute respiratory distress syndrome (ARDS) during a reversed, sequential ramp procedure of positive end-expiratory pressure (PEEP) changes to investigate the potential...

BACKGROUND The aim of this study was to evaluate the response of common sized fiber-reinforced composites (FRCs) to different deflections due to bending forces and comparing it with stainless steel (SS) wires. MATERIALS AND METHODS In this experimental study, two FRC groups with 0.75 mm and 1.2 mm diameters (Everstick Ortho, Stick Tech, Finland) and three SS groups with 0.016 × 0.022 inch, 0....

Previous studies have shown conflicting results on the effect of lung volume on the diaphragm compound muscle action potential (CMAP). Consequently, the ability to quantify the oesophageal diaphragm electromyography (EMG) has been questioned. If lung volume changes have little effect on the diaphragm CMAP the accurate measurement of voluntary EMG, as an index of respiratory drive, may be possib...

PURPOSE This study evaluated the load bearing capacity of anatomically designed canines restored with FRC posts and experimental short fiber composite resin (FC). The effect of using three different types of tooth preparation and woven net on the fracture load was also investigated. Further aim was to evaluate the failure mode of each restoration. MATERIAL AND METHODS 80 maxillary frasaco-can...

Background: We measured Functional Residual Capacity (FRC) of the lungs with three methods in healthy volunteers. The three techniques included a CO2 partial rebreathing technique, nitrogen washout technique, and the reference technique for ambulatory patients, body plethysmography. Materials and Methods: After granting consent to an IRB-approved protocol, each of the 20 healthy volunteers part...

Fuzzy relational classifier (FRC) is a recently proposed two-step nonlinear classifier. At first, the unsupervised fuzzy c-means (FCM) clustering is performed to explore the underlying groups of the given dataset. Then, a fuzzy relation matrix indicating the relationship between the formed groups and the given classes is constructed for subsequent classification. It has been shown that FRC has ...

In newborn infants, thoraco-abdominal surgery is a serious intervention with respect to gas exchange and lung mechanics. This prospective clinical study compared surgery-induced changes in functional residual capacity (FRC) and ventilation inhomogeneity (VI) indices with changes in conventional monitoring parameters. Of 29 ventilated newborns (mean weight 2,770+/-864 g at surgery), 13, nine and...

AIMS Ultrasound differs procedurally from the established methods for non-invasive coronary visualization and is therefore an interesting alternative for non-invasive diagnostics. In this study, fragment reconstruction of coronary arteries by transesophageal echocardiography (FRC-TEE) was investigated for the first time in a patient population being evaluated for coronary angiography. METHODS...

Introduction The advances in the materials and techniques for adhesive dentistry have allowed the development of non-invasive or minimally invasive approaches for replacing a missing tooth in those clinical situations when conservation of adjacent teeth is needed. Good mechanical and cosmetic/aesthetic properties of fiber-reinforced composite (FRC), with good bonding properties with composite r...

Purpose: Double-deck trailers could be a key contributor towards the UK’s commitment to reducing CO2 emissions towards 2020. A double-deck trailer greatly increases carrying capacity with current vehicle size and weight limits. Double-deck trailers are particularly well suited to retail distribution. This paper introduces a model that calculates the financial and environmental impact of deployi...
