La ética en las Relaciones Públicas

In this article the author reflects about entailment of ethics and public relations, reviewing the discussion on the role of ethics within the profession. This subject, that has been intensively discussed, implies several variables like present legislation, the norms that rules the daily activity of communicators and the philosophical direction of the person who exerts the profession. The author analyzes that public relations people often must apply their own perspective to judge whether actions to generate bonds and to create relations between the organization and her public ‘are right or not’, having to announce the benefits and damages of their activities of communication.En este artículo el autor reflexiona acerca de la vinculación de la ética y las Relaciones Públicas, revisando la discusión sobre el papel de la ética dentro de la profesión.

Electrochemosensor for Trace Analysis of Perfluorooctanesulfonate in Water Based on a Molecularly Imprinted Poly(o-phenylenediamine) Polymer

This work is aimed at developing an electrochemical sensor for the sensitive and selective detection of trace levels of perfluorooctanesulfonate (PFOS) in water. Contamination of waters by perfluorinated alkyl substances (PFAS) is a problem of global concern due to their suspected toxicity and ability to bioaccumulate. PFOS is the perfluorinated compound of major concern, as it has the lowest suggested control concentrations. The sensor reported here is based on a gold electrode modified with a thin coating of a molecularly imprinted polymer (MIP), prepared by anodic electropolymerization of o-phenylenediamine (o-PD) in the presence of PFOS as the template. Activation of the sensor is achieved by template removal with suitable a solvent mixture. Voltammetry, a quartz crystal microbalance, scanning electron microscopy and elemental analysis were used to monitor the electropolymerization process, template removal, and binding of the analyte. Ferrocenecarboxylic acid (FcCOOH) has been exploited as an electrochemical probe able to generate analytically useful voltammetric signals by competing for the binding sites with PFOS, as the latter is not electroactive. The sensor has a low detection limit (0.04 nM), a satisfactory selectivity, and is reproducible and repeatable, giving analytical results in good agreement with those obtained by HPLC-MS/MS analyses

PRELIMINARY ASSESSMENT ON THE ELECTROCHEMICAL SYNTHESIS OF 1-D JANUS PARTICLES FOR CHEMICAL SENSING PURPOSES

The dual nature of Janus particles (JPs) confers upon them fascinating properties. The name of this particles is referred to the Roman god of gates, having two opposite and distinct faces. In practice, the term Janus Particles defines all those particles displaying a dual anisotropic structure, in which two parts with distinct characteristics can be distinguished. Possible architecture for JPs are schematized in Fig. 1. Figure 1. Different Janus Particles arrangements. JPs have been prepared by a variety of methods, including: surface coating, biphasic electrified jetting, photo-polymerization in microfluidic channels, polymer self-assembly (1). Bipolar electrochemistry (2) have been applied to the goal of preparing JPs, with the advantages of requiring simple and cheap instrumentation as well as being potentially suitable for relatively large scale production. In this communication, we describe the electrochemical preparation of Janus like 1-D nanowires (J-NWs) in particular by bipolar electrochemistry and by membrane templated electrochemical deposition (3) exploiting the experimental set-up recently proposed (4). Advantages and limits of bipolar electrochemistry vs. template deposition are critically evaluated, taking into account that the final goal of this study is the synthesis of 1D JPs suitable for analytical applications, based on differentiated self-assembly of the J-NWS in response to changes of the chemical environment in which they are suspended.

Effects of a Mask on Breathing Impairment During a Fencing Assault: A Case Series Study

Background: Fencers often complain of progressive difficulty in breathing during matches, which is generally attributed to restricted air, light and heat circulation from wearing a mask. Physiologically, the nasal structure generates airflow resistance that can reach -50% of the total respiratory resistance. Objectives: This study aims to investigate the presence of nasal obstruction in fencers and the relationship with the use of mask. Materials and Methods: An observational study on 40 fencers (18 males, 22 females) was conducted. Fencers perform a usual assault, wearing the mask and standardized physical exercises (running, sprints and obstacles) without the mask. ENT examination with a nasal flexible fiberscope, Anterior Active Rhinomanometry (AAR) and Peak Nasal Inspiratory Flow (PNIF) measurement before and after physical activity with or without the mask was recorded. Results: Before physical exercise, the total nasal airway resistance mean value for AAR was 0.33 ± 0.17 Pa/cm3/s at 150 Pa. After a match with the mask, the mean value was 0.28 ± 0.16 Pa/cm3/s. After normal physical exercises without mask, the mean value was 0.24 ± 0.15 Pa/cm3/s. Using t tests, statistically significant difference between nasal resistance before and after physical activity (P < 0.05) was observed, but no significant difference in nasal resistance between the basal value and that taken after a match wearing the masks (P = 0.1265). PNIF values significantly increase with exercise (P < 0.05). Conclusions: Our study shows that wearing the mask causes increased breathing impairment in fencers, when compared with similar physical activity without the mask
