The need to grow, learn and develop – how does management affect motivation for professional development?

2018

This article argues that knowledge management and social recognition is important for organisational learning and professional self-esteem in academic libraries. An anonymous survey was issued in 2016 to investigate how library staff’s self-esteem is affected by how they experience their management’s view and overview of their knowledge. The need for what Axel Honneth refers to as social recognition will also be discussed as an important part of how professional self-esteem and work satisfaction is experienced and further how this affects motivation to participate in professional development.

Estudio bibliométrico de producción y consumo de la revista Farmacia Hospitalaria (2004-2012)

2014

Objetivo: Analizar la actividad científica y la producción de información de la revista Farmacia Hospitalaria como publicación científica española de referencia en el área de la farmacia. Método: Estudio descriptivo transversal de los resultados obtenidos del análisis bibliométrico de los artículos publicados en la revista, obteniéndose los datos de la consulta directa y acceso, vía Internet, a la literatura científica recogida en la versión electrónica de la revista en el periodo 2004 a 2012. Resultados: Durante el periodo estudiado se publicaron 756 artículos. El número de originales fue de 258 (34,13%), siendo el índice de productividad de 2,40. Se identificaron 246 instituciones con tra…

[EN] Objectives. Prior to starting up the University of Valencia's (UV) institutional repository, we assessed this institution's real output of periodical publications and drew up the most comprehensive list possible. We also described the visibility of the contents on the Internet. -- Method. We searched the ISSN database and the UV's library catalogue for journals in which the UV is included in the statement of responsibility. -- Results. These two sources did not provide sufficient information, as the University was not listed in all the relevant journals as a publishing entity. In total, 162 journals were found, of which 34.6% are still published. Many have been out of print since the 1…

Dental management of patients receiving anticoagulant and/or antiplatelet treatment

2013

Introduction: Adequate hemostasis is crucial for the success of invasive dental treatment, since bleeding problems can give rise to complications associated with important morbidity-mortality. The dental treatment of patients who tend to an increased risk of bleeding due to the use of anticoagulant and/or antiplatelet drugs raises a challenge in the daily practice of dental professionals. Adequate knowledge of the mechanisms underlying hemostasis, and the optimized management of such patients, are therefore very important issues. Objectives: A study is made of the anticoagulant / antiplatelet drugs currently available on the market, with evaluation of the risks and benefits of suspending su…

Effect of short-chain alcohols on surfactant-mediated reversed-phase liquid chromatographic systems.

2010

The behaviour of β-blockers in a reversed-phase liquid chromatographic (RPLC) column with mobile phases containing a short-chain alcohol (methanol, ethanol or 1-propanol), with and without the surfactant sodium dodecyl sulphate (SDS), was explored. Two surfactant-mediated RPLC modes were studied, where the mobile phases contained either micelles or only surfactant monomers at high concentration. Acetonitrile was also considered for comparison purposes. A correlation was found between the effects of the organic solvent on micelle formation (monitored by the drop weight procedure) and on the nature of the chromatographic system (as revealed by the retention, elution strength and peak shape of…

Performance of different C18 columns in reversed-phase liquid chromatography with hydro-organic and micellar-organic mobile phases

2014

Column selection in reversed-phase liquid chromatography (RPLC) can become a challenge if the target compounds interact with the silica-based packing. One of such interactions is the attraction of cationic solutes to the free silanols in silica-based columns, which is a slow sorption-desorption interaction process that gives rise to tailed and broad peaks. The effect of silanols is minimised by the addition of a competing agent in the mobile phase, such as the anionic surfactant sodium dodecyl sulphate (SDS). In micellar-organic RPLC, the adsorption of an approximately fixed amount of SDS monomers gives rise to a stable modified stationary phase, with properties remarkably different from th…

Reversed phase liquid chromatography for the enantioseparation of local anaesthetics in polysaccharide-based stationary phases. Application to biodeg…

2020

[EN] A comprehensive study on the chiral separation of bupivacaine, mepivacaine, prilocaine and propanocaine with eight commercial polysaccharide-based chiral stationary phases (CSPs) in reversed phase conditions compatible with MS detection is performed. Methanol and acetonitrile are used as organic modifiers. Retention and resolution values obtained for each compound in the different CSPs and mobile phases are compared. The polysaccharide-based CSPs tested present different enantioselectivity towards the analytes. From the results, the experimental conditions for determining the enantiomers of bupivacaine, mepivacaine, prilocaine and propanocaine in saline aqueous samples using MS detecti…

Novel solutions for closed-loop Reverse Electrodialysis: thermodynamic characterisation and perspective analysis

2019

Abstract Closed-loop Reverse Electrodialysis is a novel technology to directly convert low-grade heat into electricity. It consists of a reverse electrodialysis (RED) unit where electricity is produced exploiting the salinity gradient between two salt-water solutions, coupled with a regeneration unit where waste-heat is used to treat the solutions exiting from the RED unit and restore their initial composition. One of the most important advantages of closed-loop systems compared to the open systems is the possibility to select ad-hoc salt solutions to achieve high efficiencies. Therefore, the properties of the salt solutions are essential to assess the performance of the energy generation a…
