The influence of the sea and topography are vital factors in the atmospheric processes affecting any island, as they introduce peculiarities in the hydrosedimentary response of fluvial systems. In view of that, the relationship between the surface atmospheric conditions (weather types, WTs), rainfall, runoff and erosion dynamics in three small catchments located in Mallorca were analysed. The catchments are representative in terms of geomorphology and land use but also due to their location within the major rainfall areas previously identified in the island by (Sumner et al., 1993). Data of rainfall, runoff and sediment variables, coupled with calculated WTs were used for the 2013–2017 period. WTs frequency and distribution during this period were compared to the last climatic period reference (1981–2010) to test the climate validity of the study period. The results illustrated how hydrosedimentary response was mostly caused by eco-geographical patterns but also by differences in the response of each catchment to WTs, related to the intrinsic geographical position in the island and different exposures to humid winds. Anticyclonic WT was the most frequent, despite it being only involved in one flood event at the eastern catchment. Conversely, eastern and northeastern WTs generated more than 85% of the total runoff and sediment, representing only 39% of flood events. The understanding of the specific role of WTs on the island's hydrology was improved, considering that freshwater resources are scarce and eco-sociologically crucial.

[spa] La pandemia creada por la COVID19 está revisando todos los protocolos que hasta ahora se venían poniendo en marcha en la sanidad pública. Uno de ellos es el abastecimiento de equipos de protección individual de los centros sanitarios y hospitales que se vio comprometido durante los primeros meses de una pandemia con afectación global. Depender del suministro exterior de equipos de protección personales no contribuye a una rápida respuesta de protección. El proyecto Mask3D4All pretende definir un proceso de autoproducción de mascarillas faciales con capacidades virucidas mediante la evaluación de técnicas de fabricación 3D y la incorporación de soluciones salinas en los elementos filtrantes. Los resultados de este proyecto permitirán definir un protocolo de autoprotección no solo válido para los puntos calientes sanitarios, sino también para la protección del resto de la población y centros sociales al basar los estudios en materiales de fabricación nacional para afrontar un posible cierre del comercio entre países., [eng] All the protocols that have been implemented up to now in public health are reviewing due to the pandemic created by COVID19. One of them is the supply of individual protection equipment to health centers and hospitals that was compromised during the first months of a globally affecting pandemic. Relying on the outside supply of personal protective equipment does not contribute to a rapid protection response. The Mask3D4All project aims to define a process for the self-production of face masks with virucidal capabilities through the evaluation of 3D manufacturing techniques and the incorporation of saline solutions in the filter elements. The results of this project will make it possible to define a self-protection protocol not only valid for health hot spots, but also for the protection of the rest of the population and social centers by basing the studies on nationally manufactured materials to face a possible closure of trade between countries.

Obtaining representative hydrometric values is essential for characterizing extreme events, hydrological dynamics and detecting possible changes on the long-term hydrology. Reliability of streamflow data requires a temporal continuity and a maintenance of the gauging stations, which data are affected by epistemic and random sources of error. An assessment of discharge meterings' and stage-discharge rating curves' uncertainties were carried out by comparing the accuracy of the measuring instruments of two different hydrometric networks (i.e., one analogical and one digital) established in the same river location at the Mediterranean island of Mallorca. Furthermore, the effects of such uncertainties were assessed on the hydrological dynamics, considering the significant global change impacts beset this island. Evaluation was developed at four representative gauging stations of the hydrographic network with analogic (≈40 years) and digital (≈10 years) data series. The study revealed that the largest source of uncertainty in the analogical (28 to 274%) and in the digital (17–37%) networks were the stage-discharge rating curves. Their impact on the water resources was also evaluated at the event and annual scales, resulting in an average difference of water yields of 183% and 142% respectively. Such improvement on the comprehension of hydrometric networks uncertainties will dramatically benefit the interpretation of the long-term streamflow by providing better insights into the hydrologic and flood hazard planning, management and modelling. © 2019

[EN] This paper presents a wireless system to send biosignals outside a hyperbaric chamber avoiding wires going through the chamber walls. Hyperbaric chambers are becoming more and more common due to new indications of hyperbaric oxygen treatments. Metallic walls physically isolate patients inside the chamber, where getting a patient's vital signs turns into a painstaking task. The paper proposes using a ZigBee-based network to wirelessly transmit the patient's biosignals to the outside of the chamber. In particular, a wearable battery supported device has been designed, implemented and tested. Although the implementation has been conducted to transmit the electrocardiography signal, the device can be easily adapted to consider other biosignals.

[EN] This paper presents a wireless ZigBee-based system to replace the traditional wired communication link of the hyperbaric chambers, which allows reducing the costs of seals capable of withstanding the internal pressures and giving rise to a more versatile system. The system is able to capture and process individual vital signs like the electrocardiography signal, and other four analogue sources, sending the data to an external computer allowing analysis, representation and sharing them with the medical staff. This work solves problems such as the attenuation of the signal produced by the metal walls of the hyperbaric chamber obtaining a coverage area big enough to manage up to six patients with an effective data rate conversion of 2kHz. Furthermore, a battery-based and multi-parameter platform is designed for multi-patient hyperbaric chambers.

The experience in the Pariatge County, Mallorca Wildfires are one of the most significant driving factors in desertification processes. Furthermore, insular territories such Mallorca are more affected by human impacts due to their intrinsic socioecological fragility. The increase of burned surface area since 2011in Balearic Islands involves a challenge in which forest management and research through interdisciplinary and technological advances should be joined. Ecogeomorphology is an emergent discipline which allows investigating the role of geomorphic processes in the vegetation recovery. Additionally, the introduction of unmanned aerial vehicles as remotesensing tools offers new and exciting opportunities for monitoring environmental processes.

Component-based architectures can play an important role in solving some of the problems related to energy management in Wireless Sensor Networks. It has been recently shown that real-time interfaces, and their associated mechanisms for online adaptation, are useful for solving the problem of dynamically allocating bandwidth in a WSN, while still satisfying both quality and energy constraints. In this paper we will discuss the relevance of extending this model with a new parameter, the transmission power of the nodes. Based on experimental data, it will be shown that this parameter has a strong impact on both the energy consumed by the nodes and the quality/reliability of the communication. The integration of this feature with the notion real-time interface, although not completely solved, will be discussed as well.
