Carga de trabalho de enfermagem em unidade de terapia intensiva pediátrica especializada como critério para dimensionamento de pessoal

Objetivo: avaliar a carga de trabalho de enfermagem (CTE) em unidade de terapia intensiva pediátrica, especializada no atendimento de crianças com anomalias craniofaciais e síndromes associadas, como critério para dimensionamento de pessoal. Método: Estudo prospectivo, realizado na unidade de terapia intensiva pediátrica do Hospital de Reabilitação de Anomalias Craniofaciais da Universidade de São Paulo, nos meses de maio e junho de 2013. A amostra constou de 29 pacientes. O critério de inclusão foi à permanência maior que 24 horas na unidade. Inicialmente a carga de trabalho de enfermagem foi mensurada por meio do Nursing Activies Score (NAS) e posteriormente comparada ao dimensionamento de pessoal segundo a Resolução do Conselho Federal de Enfermagem - COFEN - 293/04, e aos fatores sócio-demográficos da amostra (idade, sexo, diagnóstico médico, procedência e média de permanência). Para a análise estatística, utilizouse o Teste – t de Student, a Análise de Variância e a Correlação de Pearson, observando-se como nível de significância 5% (p ≤ 0,05). Resultados: A média NAS foi de 90,86%. A taxa de ocupação foi de 60%. Ao se relacionar a CTE segundo o NAS as variáveis sócio demográficas, não se observaram diferenças significantes. O dimensionamento de pessoal segundo o NAS e segundo a Resolução COFEN - 293/04 foram similares (5 funcionários por turno de trabalho). Conclusão: O dimensionamento de pessoal segundo a carga de trabalho por meio do instrumento NAS foi similar ao preconizado pelo COFEN. Evidencia-se a relação entre a carga de trabalho e o dimensionamento de pessoal.

Dynamics of photoexcited carriers in the presence of disorder in radial heterostructured GaAs/AlGaAs/GaAs nanowires

Time-resolved photoluminescence was employed to study electron-hole dynamics in radial heterostructured GaAs/AlGaAs/GaAs core/inner shell/outer shell nanowires. It was found that impurity random potential results in a red shift of the recombination time maximum with respect to the photoluminescence peak energy.

La optimización mediante algoritmos genéticos del proceso de deslastre y reposición de carga

[ES] La satisfacción de los consumidores de electricidad está muy correlacionada con las frecuencias de las interrupciones del suministro de energía eléctrica y con la duración de las mismas. Actualmente los deslastres de potencia, entendiendo éstos como el conjunto de cortes de suministro de energía eléctrica en ciertas zonas por causa de fallos imprevistos en el sistema eléctrico, se realizan con relés de subfrecuencia mediante criterios de cortes fijos. Este proyecto de investigación propone nuevas pautas de actuación para deslastrar y reponer, enmarcadas de forma no tan rígida y acorde al estado del sistema en cada momento.

High precision radial velocities with giano spectra

Radial velocities measured from near-infrared (NIR) spectra are a potential tool to search for extrasolar planets around cool stars. High resolution infrared spectrographs now available reach the high precision of visible instruments, with a constant improvement over time. GIANO is an infrared echelle spectrograph and it is a powerful tool to provide high resolution spectra for accurate radial velocity measurements of exo-planets and for chemical and dynamical studies of stellar or extragalactic objects. No other IR instruments have the GIANO's capability to cover the entire NIR wavelength range. In this work we develop an ensemble of IDL procedures to measure high precision radial velocities on a few GIANO spectra acquired during the commissioning run, using the telluric lines as wevelength reference. In Section 1.1 various exoplanet search methods are described. They exploit different properties of the planetary system. In Section 1.2 we describe the exoplanet population discovered trough the different methods. In Section 1.3 we explain motivations for NIR radial velocities and the challenges related the main issue that has limited the pursuit of high-precision NIR radial velocity, that is, the lack of a suitable calibration method. We briefly describe calibration methods in the visible and the solutions for IR calibration, for instance, the use of telluric lines. The latter has advantages and problems, described in detail. In this work we use telluric lines as wavelength reference. In Section 1.4 the Cross Correlation Function (CCF) method is described. This method is widely used to measure the radial velocities.In Section 1.5 we describe GIANO and its main science targets. In Chapter 2 observational data obtained with GIANO spectrograph are presented and the choice criteria are reported. In Chapter 3 we describe the detail of the analysis and examine in depth the flow chart reported in Section 3.1. In Chapter 4 we give the radial velocities measured with our IDL procedure for all available targets. We obtain an rms scatter in radial velocities of about 7 m/s. Finally, we conclude that GIANO can be used to measure radial velocities of late type stars with an accuracy close to or better than 10 m/s, using telluric lines as wevelength reference. In 2014 September GIANO is being operative at TNG for Science Verification and more observational data will allow to further refine this analysis.

Radial dGEMRIC in developmental dysplasia of the hip and in femoroacetabular impingement: preliminary results

On-table reconstruction of comminuted fractures of the radial head

The most widely accepted treatment for comminuted fractures of the radial head is either the excision or open reduction and internal fixation. The purpose of the present study is to evaluate the value of an 'on-table' reconstruction technique in severely comminuted fractures of the radial head. In this study, two patients with a Mason type-III and four patients with a Mason type-IV radial-head fracture were treated with 'on-table' reconstruction and fixation using low-profile mini-plates. After a mean follow-up of 112 months (47-154 months), the mean elbow motion was 0-6-141 degrees extension flexion with 79 degrees of pronation and 70 degrees of supination. The mean Broberg and Morrey functional rating score was 97.0 points, the Mayo Elbow Performance Index was 99.2 points and the mean Disabilities of the Arm, Shoulder, and Hand (DASH) Outcome Measure score was 1.94 points. One patient had symptoms of degenerative changes, with a slight joint-space narrowing. There were no radiographic signs of devitalisation at final examination. Comminuted fractures of the radial head, which would otherwise require excision, can be successfully treated with an 'on-table' reconstruction technique.

Persistent sensitivity disorders at the radial artery and saphenous vein graft harvest sites: a neglected side effect of coronary artery bypass grafting procedures

The use of radial artery conduits in coronary artery bypass grafting (CABG) surgery is associated with improved long-term patency and patient survival rates as compared with saphenous vein conduits. Despite increasing popularity, relative incidence of local harvest-site complications and subjective perception of adverse long-term sequelae remain poorly described.
