Smertekartlegging og smertelindring hos pasienter med demens: Utfordringer og dilemmaer

2013

Published version of an article in the journal: Vård i Norden. Also available from the publisher at: http://www.artikel.nu/Public/Main.aspx Aim: to explore nurses' experiences with pain assessment and pain relieving in patient with dementia. Background: research shows that patients with dementia are still suffering from unnecessary pain. The reason it may be nurses difficulty to interpret and map patients’ pain. Method: data were collected through three different focus group interviews. A semi – structured interview guide was developed to answer the research question. Data were analyzed by using a content analysis in four steps. Findings: The findings are divided into three sub – categories…

High flow nasal therapy in perioperative medicine: from operating room to general ward

2018

Abstract Background High flow nasal therapy (HFNT) is a technique in which humidified and heated gas is delivered to the airways through the nose via small nasal prongs at flows that are higher than the rates generally applied during conventional oxygen therapy. The delivered high flow rates combine mixtures of air and oxygen and enable different inspired oxygen fractions ranging from 0.21 to 1. HFNT is increasingly used in critically ill adult patients, especially hypoxemic patients in different clinical settings. Main body Noninvasive ventilation delivers positive pressure (end-expiratory and inspiratory pressures or continuous positive airway pressure) via different external interfaces. …

Paramagnetic germanium-related centers induced by energetic radiation in optical fibers and preforms

2009

International audience; We investigated the creation processes of Ge-related paramagnetic point defects in silica fibers and preforms, doped with different amounts of germanium, and X-ray irradiated at several radiation doses. Different paramagnetic defect species, like GeE0, Ge(1) and Ge(2), were revealed by electron paramagnetic resonance measurements and their concentration was studied as a function of the irradiation dose. The comparison with the optical absorption spectra points out the main role of Ge(1) on the optical transmission loss of fibers in the UV region.

Advanced Optical Processing of Microwave Signals

2005

The authors present a review on the recent approaches proposed to implement transversal RF filters. Different tunable transversal filters consisting of wavelength tunable optical taps and those employing the tunability of dispersive devices are presented showing their high-performance characteristics. A comprehensive review of the fundamentals and a discussion on the main limitation of these structures are also included.

Automatic EMI filter design for power electronic converters oriented to high power density

2018

In this paper, a complete computer aided procedure based on the power density concept and aimed at the automatic design of EMI filters for power electronic converters is presented. It is rule-based, and it uses suitable databases built-up by considering information on passive components available from commercial datasheets. The power density constraint is taken into consideration by imposing the minimization of the filter volume and/or weight; nevertheless, the system in which the automatically designed filter is included satisfies the electromagnetic compatibility standards limits. Experimental validations of the proposed procedure are presented for two real case studies, for which the per…

Impeller optimization in crossflow hydraulic turbines

2021

Crossflow turbines represent a valuable choice for energy recovery in aqueducts, due to their constructive simplicity and good efficiency under variable head jump conditions. Several experimental and numerical studies concerning the optimal design of crossflow hydraulic turbines have already been proposed, but all of them assume that structural safety is fully compatible with the sought after geometry. We show first, with reference to a specific study case, that the geometry of the most efficient impeller would lead shortly, using blades with a traditional circular profile made with standard material, to their mechanical failure. A methodology for fully coupled fluid dynamic and mechanical …

Joint Power Allocation and Link Selection for Multi-Carrier Buffer Aided Relay Network

2019

In this paper, we present a joint power allocation and adaptive link selection protocol for an orthogonal frequency division multiplexing (OFDM)-based network consists of one source node i.e., base station (BS), one destination node i.e., (MU) and a buffer aided decode and forward (DF) relay node. Our objective is to maximize the average throughput of the system via power loading over different subcarriers at source and relay nodes. A separate power budget is assumed at each transmitting node to make the system more practical. In order to form our solution more tractable, a decomposition framework is implemented to solve the mixed integer optimization problem. Further, less complex suboptim…

Arquitectura renacentista "inacabada" de Jerónimo Quijano y su integración en determinados templos de origen gòtico

2014

Jerónimo Quijano fue un arquitecto español que destacó durante la etapa del Renacimiento Pleno en España en el tercio central del siglo XVI. Los edificios seleccionados principalmente son: iglesia de Santiago de Orihuela –Alicante– e iglesia de Santa María del Salvador de Chinchilla –Albacete–. En ambos se construyó una nueva cabecera renacentista e integrada en una nave gótica preexistente y en el caso de haber sido “acabadas” íntegramente con el criterio del maestro serían sin duda ejemplos claves del Renacimiento español. En Orihuela se percibe la necesidad de “descubrir” visualmente el magnífico arco de triunfo romano que hace de portada de la nueva cabecera renacentista, sugiriendo así…
