Extracorporeal life-support systems are valuable tools to treat patients with acute cardiopulmonary failure in intensive care facilities, and highly suitable for the interhospital transfer of critically ill specialized centers. This article reviews cannulation strategies associated vascular complications our institution.Between January 2004 December 2009, 464 extracorporeal were implanted via percutaneous at institution. The type incidence adverse events related access femoral, subclavian...
An adapted bench-scale Mass Loss Calorimeter (MLC) device for evaluating forest fuel flammability and combustion properties is proposed. This fire test apparatus consists of an MLC fitted with a chimney containing thermopile. After the thermopile output has been calibrated by use methane burner, these data are used to quantify heat release, as alternative classical measurement oxygen consumption due combustion. The results showed good repeatability reasonable approximation HRR values...
Two broadband very low-noise amplifiers operating in the frequency range from 4 to 12 GHz at cryogenic temperature are presented. The amplifier circuits have been developed using a 100 nm gate length InAlAs/InGaAs metamorphic high electron mobility transistor (mHEMT) technology. three-stage monolithic microwave integrated circuit (MMIC) chips manufactured coplanar At first MMIC achieved linear gain of 22 dB and an average noise 11.6 K with power dissipation 41 mW. second amplifier, external...
Experimental tests were carried out with an adapted bench-scale mass loss calorimeter (MLC) and also in outdoor wind tunnel to estimate the heat release rate (HRR) of a forest fuel bed. The MLC apparatus uses calibrated thermopile quantify HRR, as alternative classical measurement oxygen consumption due combustion. Additional calibration thermocouples measure gas temperatures enabled estimation HRR experimental burnings conducted tunnel. results showed reasonable agreement between peak...
MMIC Broadband Low Noise Amplifiers (LNA) for radio astronomy applications with 100 nm GaAs metamorphic High Electron Mobility Transistor (mHEMT) process have been developed. Cryogenic performance of a 4–12 GHz and 25–34 LNAs is presented. The LNA cooled at 15 K exhibits an associated gain 31.5 dB ± 1.8 average noise temperature 5.3 low power dissipation 8 mW. Cooled to the amplifier has demonstrated flat 24.2 0.4 15.2 temperature, very 2.8 mW on chip. mHEMT based MMICs excellent...
This work proposes a persuasion model based on argumentation theory and users’ characteristics for improving the use of resources in bike sharing systems, fostering bicycles thus contributing to greater energy sustainability by reducing carbon-based fuels. More specifically, it aims achieve balanced network pick-up drop-off stations urban areas with help users, dedicated management trucks that redistribute bikes among stations. The proposal persuade users choose different routes from...
Shrubland are one of the main communities affected by wildland fires, both in forested and unforested areas.However, empirical models predicting fire behaviour these scarce.One reason explaining lack knowledge is difficulty obtaining data to develop kinds models.Wind tunnel experimental fires have been carried out different shrubland fuel complexes (Ulex europaeus L. Pterospartum tridentatum (L.) Willk.)collected Galicia (NW Spain).Rate spread recorded laboratory tests compared with...

The advancement of Radio Astronomy instruments pushes innovation in several fronts. Sensitivity aside, one way which cryogenic receivers can be upgraded is by increasing the number beams single dish antennas, building what commonly known as a Focal Plane Array (FPA). In this paper we present novel reduced input reflection 4–12 GHz Low Noise Amplifier (LNA) for Intermediate Frequency (IF) millimeter wave superheterodyne multipixel with Superconductor-Insulator-Superconductor (SIS) mixers. aim...
In this work an adapted bench-scale Mass Loss Calorimeter (MLC) device is used to measure HRR for forest fuels.The MLC has the same heating unit as a standard cone calorimeter, but a) physical basis in (by using calibrated thermopile) different than one calorimeter (oxygen consumption method) and b) MCL does not have concentration of gases produced during combustion.Although values are essential curves, their knowledge great interest characterize combustion process efficiency.In sense,...
Metallic nanostructures have attracted large interest recently due to new optical properties caused by plasmonic effects. The exceptionally high transmission of light through periodically structured metals is originated interactions between and resonances. These resonances are controllable varying periodicity geometrical dimensions the metal gratings. Our aim utilization these effects improve efficiency conventional light-emitting diodes (LED). application one-dimensional periodic metallic...

Objectives: Coronary artery bypass grafting (CABG) with conventional extracorporeal circulation (CECC) in emergency patients is associated increased mortality. The proposed advantages of minimized (MECC) on outcome after CABG were evaluated.
Background: Renal dysfunction is common after cardiac surgery. Little known on the impact of minimized extracorporeal circulation (MECC) development impaired kidney function coronary bypass grafting (CABG).
Background: Cardiopulmonary bypass induces hemolysis and the activation of inflammatory coagulation systems as a result combination mechanical trauma biological mechanisms. The aim was to evaluate performance two different minimized extracorporeal circulation (ECC) systems, compare their influence on blood components.
Aims: During cardioplegic arrest the patient's complete gas exchange is accomplished by extracorporeal circulation. Oxygen consumption (VO2) depends not only from temperature, but also anaesthetic technique and intraoperative drug management.
Aims: Outcome in cardiac surgical procedures is mainly defined by mortality and morbidity. Quality of life, the patient's view, rarely assessed. The aim this study was to evaluate health related quality life (HRQL) after complex surgery ascending aorta aortic arch, determine factors influencing HRQL.
