-A Web application of a ventilator simulation system was developed for the students of clinical engineering and health care professionals. The system runs on Internet Explorer (5.5 or higher) and was developed using HTML, VBScript and Active X control (tklsim.ocx 70kB). The system was composed of a ventilator module and a respiratory model module. The ventilator module makes various waveforms o...

Prolonged mechanical ventilation (MV) results in oxidative damage in the diaphragm; however, it is unclear whether this MV-induced oxidative injury occurs rapidly or develops slowly over time. Furthermore, it is unknown whether both soluble (cytosolic) and insoluble (myofibrillar) proteins are equally susceptible to oxidation during MV. These experiments tested two hypotheses: 1). MV-induced ox...

Mechanical ventilation is an important and ever-evolving component of everyday critical care. Clinicians can struggle to keep up with current literature and descriptions of advancement in a way that they can apply these changes to their bedside patient care. This article serves as a review of important recent findings related to invasive mechanical ventilation and describes their relevance to b...

BACKGROUND This clinical practice guideline addresses six questions related to liberation from mechanical ventilation in critically ill adults. It is the result of a collaborative effort between the American Thoracic Society (ATS) and the American College of Chest Physicians (CHEST). METHODS A multidisciplinary panel posed six clinical questions in a population, intervention, comparator, outc...

This paper presents an analytical solution for response of a piezoelectric hollow cylinder under two-dimensional electro thermo mechanical fields. The solution is based on a direct method and the Navier equations were solved using the complex Fourier series. The advantage of this method is its generality and from mathematical point of view, any type of the thermo mechanical and electrical bound...

in this study, physical vapor deposition (pvd) ti-cr-n coatings were deposited at two different temperatures100 and 400ºc on hardened and tempered tool steel substrates. the influence of the applied deposition temperature on the physical and mechanical properties of coatings such as roughness, thickness, phase composition, hardness and young’s modulus were evaluated. phase compositions were stu...

Mechanical Ventilation provides a comprehensive theoretical background and practical approach to mechanical ventilation. It is written primarily for respiratory therapists, but critical care and respiratory physicians and nurses will find many aspects of the book invaluable, particularly the clear and concise descriptions of the different modes of mechanical ventilation, their advantages and di...

In this paper a multiphysics approach to study the optical properties of integrated waveguides influenced by thermal and mechanical stress is presented. The heating and pressure effects are evaluated by means the Heat Transfer and Structural Mechanics modules respectively. Finally, the Electromagnetics Module is used in order to evaluate the optical eigenfunctions and eigenvalues.

In this paper we introduce an approach to model technological process of manufacture of a field-effect heterotransistor. The modeling gives us possibility to optimize the technological process to decrease length of channel by using mechanical stress. As accompanying results of the decreasing one can find decreasing of thickness of the heterotransistors and increasing of their density, which wer...

a bionanocomposite film was developed by nanoclay incorporation to chitosan films, using a solution casting method and the effects of nanoclay concentration (0.5, 1.0, and 3% w/w) on the physical and mechanical properties of the chitosan films were evaluated. moreover, x-ray diffraction (xrd), scanning electron microscopy, and fourier transform infrared spectra (ftir) were used for studying mic...
