Transferencia génica hepática hidrodinámica en modelos de cerdo in vivo y segmento humano ex vivo
2015
Introducción: La terapia génica es una estrategia terapéutica que pretende utilizar ácidos nucleicos como medicamentos para el tratamiento temporal o permanente de patologías hereditarias o adquiridas. En base al vehículo utilizado para entregar el gen, podemos clasificar la terapia génica en dos grupos: la terapia génica viral (vectores virales) y la terapia génica no viral (vectores no virales o ADN desnudo). La terapia no viral resulta menos eficiente pero más segura. La hidrofección (transferencia génica hidrodinámica) ha mostrado un gran potencial, con resultados terapéuticos en ratón. Sin embargo, cuando la hidrofección se ha trasladado a animales de mayor tamaño, el procedimiento ha …
The thermal performances of historic masonry: In-situ measurements of thermal conductance on calcarenite stone walls in Palermo
2018
Abstract Rich literature explores materials and construction techniques of historic buildings, but limited information is available about the thermal and hygrometric features of their envelope. Nevertheless, accurate hygrothermal data are essential for identifying effective energy upgrade measures, which must be compatible with the conservation of the architectural heritage. In order to fill this gap, it is necessary to refer to local contexts, where the variety of historic buildings is limited and their material and construction features are comparable. This paper focuses on historic masonry walls and discusses the results of twenty in-situ measurements of thermal conductance, performed al…
Stationary, Second Use Battery Energy Storage Systems and Their Applications: A Research Review
2021
The global demand for electricity is rising due to the increased electrification of multiple sectors of economic activity and an increased focus on sustainable consumption. Simultaneously, the share of cleaner electricity generated by transient, renewable sources such as wind and solar energy is increasing. This has made additional buffer capacities for electrical grids necessary. Battery energy storage systems have been investigated as storage solutions due to their responsiveness, efficiency, and scalability. Storage systems based on the second use of discarded electric vehicle batteries have been identified as cost-efficient and sustainable alternatives to first use battery storage syste…
Sisäistyneet ristiriidat, tunnetyö ja tietotyöläissubjektiviteetin rakentuminen
2015
Yliopistotyö on esimerkki uuden työn muodoista, joissa työ kiinnittyy aiempaa vahvemmin yksilöön. Samalla vastuu työelämän vaatimuksiin yltämisestä siirtyy työntekijälle itselleen. Työyhteisön ristiriitatilanteissa organisaation ongelmat sisäistyvät työntekijän yksityisiksi ja tunne-elämän ongelmiksi.
Kliinisestä harjoittelusta työssäoppimiseen ja yhteistyötiimeihin
2002
Terveysalan työharjoittelun toteutumista on arvosteltu siitä, että oppilaitokset panostavat entistä vähemmän työharjoittelun ohjaukseen ja harjoittelupaikkojen kanssa tehtävään yhteistyöhön. Harjoittelussa perinteiset työtavat ja vallitseva työkulttuuri siirretään kritiikittömästi opiskelijoille. Koulun antamat tiedot ja harjoittelupaikan edellyttämät taidot eivät kohtaa. Artikkelissa luodaan näkymiä uudenlaiseen työssäoppimiseen tehostamalla koulun ja työpaikkojen välistä yhteistyötä.
Posting and agency work in British construction and hospitality: the role of regulation in differentiating the experiences of migrants
2017
This article engages with IHRM debates on the transnational regulation of labour, exploring how migration policy and work fragmentation affect employment dynamics in multi-employer settings. It dra...
Water and Energy Saving in Urban Water Systems: The ALADIN Project
2016
The ALADIN project was aimed at contributing to environmental and energy sustainability of the urban water system by means of a decision support tool able to allow an evaluation of the energy impact related to each different macro-sectors of urban water cycle highlighting the main energy flows and to assess the system energy balance and identify the possible energy-efficient solutions. Moreover the tool suggests the most efficient actions in reducing water losses. In the present paper the main features of the developed tool are presented. (C) 2016 The Authors.

Evaluación del tratamiento farmacológico en pacientes de cuidados paliativos en una unidad de hospitalización domiciliaria
2015
La prescripción off-label es aquella conocida como “prescripción fuera de etiqueta”,es decir la utilización de los medicamentos en condiciones distintas para la que fueron aprobados (indicación, vía de administración, dosis…) y cuyas condiciones autorizadas de utilización, se encuentran recogidas en la ficha técnica del medicamento. El objetivo principal de este trabajo es describir y estimar el uso fuera de indicación autorizada de los medicamentos prescritos a los pacientes de cuidados paliativos al ingreso en una unidad de hospitalización domiciliaria (UHD) de un centro monográfico de oncología. Como objetivos secundarios se trata de clasificar y cuantificar el uso fuera de indicación au…
Damping Provision by Different Virtual Synchronous Machine Schemes
2020
The adoption of virtual synchronous machine (VSM) schemes for the control of power converters is gaining more and more attention both in academia and industry. The VSM control strategies fall into the category of grid-forming converter controls, and they are intended for a range of different applications, providing specific services and different kinds of support to the grid. The paper investigates the possibility of damping provision to the system by VSM power converters. Different schemes are considered and compared, showing the opportunity of the investigated solutions through combined modal and time domain analyses. A specific modification of the power synchronization loop is recognized…
Decoupled control scheme of grid-connected split-source inverters
2017
Grid-connected power conversion systems for renewable energy sources must fulfill several requirements, e.g., the high efficiency, the reduced cost and complexity, and, quite often, the boost capabilities that is usually achieved using a front-end dc–dc boost converter before the inversion stage, leading to a two-stage architecture. Meanwhile, single-stage power conversion systems, which perform the boosting operation within the inversion one, offer some potential advantages, in terms of reducing the complexity and the volume of the whole system. Among several proposed options, the split-source inverter (SSI) has been recently proposed by Abdelhakim et al. as an alternative option with some…
