Taxonomic composition and ecological characteristics of the endemic flora of the lower Duero Basin (Iberian Peninsula)
The taxonomical composition and an analysis of four ecological characteristics
of the 46 endemic species occurring in the lower Duero Basin (CW
Iberian Peninsula) have been made. A comparative analysis of the results
reveals that this endemic flora does not comply with the general patterns previously
observed in other floras. Predominant life forms are hemicryptophytes
(43%) and chamaephytes (22%). As far seed-dispersal is concerned, 54% of the
endemic species lack any noteworthy adaptative feature. 89% of the endemic
species are pollinated by animals (mostly by insects) and only 1 species is dioecious.
Following binary classification of the above characteristics have been
used to plot statistically significant associations.La composition taxonomique et une analyse de quatre caracteristiques
ecologiques des 46 especes endemiques rencontrees dans le bassin inferieur
du Duero (CW de Ia Peninsula lberique) ont ete realisees. Une analyse
comparative des resultats montre que cette !lore endemique ne correspond pas
aux schemas generaux observes precedemment dans d'autres flares. Les
formes biologiques predominantes son! les Mmicryptophytes (43%) et les chamephytes
(22%). En ce qui conceme le mode de dispersion des diaspores, 54%
des especes endemiques son! depourvues de tout aspect adaptatif particulier.
89% des especes endemiques son! pollinisees par des animaux (essentiellement
des insectes) et une seule espece est dioique. En se basant sur une classification

Towards a Persuasive Recommender for Bike Sharing Systems: A Defeasible Argumentation Approach
[EN] This work proposes a persuasion model based on argumentation theory and users' characteristics for improving the use of resources in bike sharing systems, fostering the use of the bicycles and thus contributing to greater energy sustainability by reducing the use of carbon-based fuels. More specifically, it aims to achieve a balanced network of pick-up and drop-off stations in urban areas with the help of the users, thus reducing the dedicated management trucks that redistribute bikes among stations. The proposal aims to persuade users to choose different routes from the shortest route between a start and an end location. This persuasion is carried out when it is not possible to park the bike in the desired station due to the lack of parking slots, or when the user is highly influenceable. Differently to other works, instead of employing a single criteria to recommend alternative stations, the proposed system can incorporate a variety of criteria. This result is achieved by providing a defeasible logic-based persuasion engine that is capable of aggregating the results from multiple recommendation rules. The proposed framework is showcased with an example scenario of a bike sharing system.This work was supported by the projects TIN2015-65515-C4-1-R and TIN2017-89156-R of the Spanish

Cystolithiase induite par la migration de la barbe de l’orge des rats (Hordeum murinum) chez 2 chiens mâles
Case ReportTwo male dogs were presented with cystic uroliths composed of magnesium ammonium phosphate (struvite). Each had an atypical nidus, a mouse barley awn (Hordeum murinum). To our knowledge, this is the first report of grass awns located in the bladder lumen of dogs. The composition of uroliths and the pathophysiology of grass awn migration to the urinary bladder are discussed.The authors are grateful for the help of Dr. Antonio Javier Sánchez-Rodríguez (Service of Microscopy of Universidad de León) for the scanning electron microscopy study, Prof. Felix Llamas and Prof. Carmen Acedo (Department of Botany of Universidad de León) for the grass awn identification and Dr. Edgardo Soriano-Vargas (CIESA, Universidad Autónoma del Estado de México) for his editorial assistance
Isotopic prediction simulations applied to high burnup samples irradiated in VANDELLÓS-II Reactor core
Isotopic content assessment has a paramount importance for safety and storage reasons. During
the latest years, a great variety of codes have been developed to perform transport and decay
calculations, but only those that couple both in an iterative manner achieve an accurate prediction of
the final isotopic content of irradiated fuels. Needless to say, them all are supposed to pass the test of
the comparison of their predictions against the corresponding experimental measures
Isotopic uncertainty assessment due to nuclear data uncertainties in high-burnup samples.
The accurate prediction of the spent nuclear fuel content is essential for its safe and optimized transportation, storage and management. This isotopic evolution can be predicted using powerful codes and methodologies throughout irradiation as well as cooling time periods. However, in order to have a realistic confidence level in the prediction of spent fuel isotopic content, it is desirable to determine how uncertainties affect isotopic prediction calculations by quantifying their associated uncertainties

Diabetes Patients' Care based on Mobile Monitoring
In this paper, we propose a new architecture for diabetes patients. These applications allow the monitoring, patient selfcontrol and communication between patient and doctor. Moreover, as an important study case, we present a mobile monitoring system which allows patients with diabetes to have a constant control of their glucose tendency as well as direct communication with their doctor. We present an application to solve this problem; we share some details of the current implementation, detailing the functionalities achieved so far.In this paper, we propose a new architecture for diabetes patients.

Occupational risk factors for shoulder chronic tendinous pathology in the Spanish automotive manufacturing sector: a casecontrol study
Background
Musculoskeletal Diseases (MSDs) are among the most prevalent health problems encountered in the workforce in Europe. Multiple risk factors contribute to their onset. In the present study, different individual risk factors for chronic tendinous pathology affecting the shoulder were analysed in a sample of workers from the automotive manufacturing sector.
Methods
An observational retrospective study was conducted with 73 cases of officially recognised and compensated occupational diseases and 94 aleatory cases of healthy workers from the same car assembly company. The experimental group comprised individuals with tendinous chronic pathology of the rotator cuff. Multiple variables that identified the risks present in the job were assessed along with participants clinical evaluation. Furthermore, two standardised guidelines for risk factors assessment were also used: the Spanish National Institute of Social Security (INSS) and the American Occupational Information Network (O*Net). Both descriptive statistical analysis and Odds ratios calculations considering the occupational disease as a dependent variable were performed.
Results
The use of hand tools, exposure to mechanical pressure in the upper limbs and awkward postures were the most prevalent risk factors. Pressure on the palm of the hand and the hand tool impacting the hand were also important risk factors. Some psychosocial factors such as lack of autonomy and mental workload were also associated shoulder tendinous diseases. The association of age, load handling, and awkward postures were the core risk factors responsible for most of the tendinous chronic injuries of the shoulder in this sample of car assembly workers.
Conclusions
Both ergonomic and psychosocial factors were present and increased the risk of developing occupational chronic tendinopathies at the shoulder in this sample of workers. Aging, load handling, and awkward postures showed the strongest predictive values. Greater knowledge of how risk factors interact would facilitate the design of better preventive workplace strategies.Medicin
