CO2N: Let's Convert!.

This projects aims to building a Website to support individuals, families, companies and other organizations in the transition towards a CO2 neutral way of living and working/producing. To this end, the site will contain a footprint calculator for CO2 emissions as well as tools to provide users with tips, advices, donations and feedback. It will also be possible to certify if a company is CO2 neutral and allow them to use a logo/stamp that they can add to their products. This project is developed under the BlendED AIM framework and with a team of 7 students from all over Europe. (4 IT, 2 Design, 1 Marketing).<br /

AMISEC: Leveraging Redundancy and Adaptability to Secure AmI Applications

Security in Ambient Intelligence (AmI) poses too many challenges due to the inherently insecure nature of wireless sensor nodes. However, there are two characteristics of these environments that can be used effectively to prevent, detect, and confine attacks: redundancy and continuous adaptation. In this article we propose a global strategy and a system architecture to cope with security issues in AmI applications at different levels. Unlike in previous approaches, we assume an individual wireless node is vulnerable. We present an agent-based architecture with supporting services that is proven to be adequate to detect and confine common attacks. Decisions at different levels are supported by a trust-based framework with good and bad reputation feedback while maintaining resistance to bad-mouthing attacks. We also propose a set of services that can be used to handle identification, authentication, and authorization in intelligent ambients. The resulting approach takes into account practical issues, such as resource limitation, bandwidth optimization, and scalability

HispaVeg: a new online vegetation plot database for Spain

We describe a new online database, named HispaVeg, which currently holds data from 2663 vegetation plots of Spanish woodlands, scrublands and grasslands. Unlike other similar databases, a detailed description of the structure is stored with the floristic data of each plot (i.e., number and physiognomy of the vertical layers, cover values for each layer).Most of the vegetation plots are large rectangles (400 to 2000 square meters) with an average of 34 species per plot. The survey dates range from 1956 to present, with most of the records between 1964 and 1994. The elevation of the plots ranges from 0 to 2880, with most of the plots between 300 and 1500 m. HispaVeg is freely available to the scientific community. Users can query the online database, view printable reports for each plot and download spreadsheet-like raw data for subsets of vegetation plots

Extensor Hallucis Capsularis o Tendón Accesorio del Extensor Hallucis Longus: Estudio anatómico y funcional, frecuencia y mediciones

The purpose of this study was to look closely at the anatomy of the extensor hallucis longus, ligament or tendon capsularis Accessory Extensor hallucis longus muscle; defi ne its occurrence frequency, it is a muscle that is not present in all feet and raises controversy in the reviewed literature. The ligament is a ligament capsularis dorsalis pedis group that accompanies the extensor hallucis longus muscle medial to it forever. We intend to demonstrate by our dissections, a ligament more common than it seems and where is its origin and insertion as well as their function, presentation and location by using photographs of cadaver feet and its width measures and characteristics. To achieve our object of study in this article, fi rst 50 dissected human cadaver fi ngers, making the relevant measurements.El objeto de éste estudio fue observar detenidamente la anatomía del Extensor Hallucis Longus, Ligamento Capsularis o Tendón Accesorio del músculo Extensor Hallucis Longus; definir su su frecuencia de aparición, pues es un músculo que no está presente en todos los pies y suscita controversia en la bibliografía consultada.El Ligamento Capsularis es un ligamento del grupo dorsal del pie, que acompaña al músculo Extensor Hallucis Longus siempre medial a él.Pretendemos demostrar con nuestras disecciones, que es un ligamento más habitual de lo que parece y, dónde está su origen e inserción, así como su función, presentación y ubicación mediante fotografías en pies de cadáver, así como medidas sobre su anchura y características particulares.Para conseguir nuestro objeto de estudio en éste artículo, se diseccionan 50 primeros dedos de cadáver humano, realizando las pertinentes mediciones

Formation of ring-like structures in flared U-discs with X-ray/FUV photoevaporation

Protoplanetary discs are complex dynamical systems where several processes may lead to the formation of ring-like structures and planets. These discs are flared following a profile where the vertical scale height increases with radius. In this work, we investigate the role of this disc flaring geometry on the formation of rings and holes. We combine a flattening law change with X-ray and FUV photoevaporative winds. We have used a semi-analytical 1D viscous α approach, presenting the evolution of the disc mass and mass rate in a grid of representative systems. Our results show that changing the profile of the flared disc may favour the formation of ring-like features resembling those observed in real systems at the proper evolutionary times, with proper disc masses and accretion rate values. However, these features seem to be short-lived and further enhancements are still needed for better matching all the features seen in real systems

Breaking down the Barrier: Topical Liposomes as Nanocarriers for Drug Delivery into the Posterior Segment of the Eyeball

Topical instillation is the most widely preferred noninvasive route of drug administration to treat diseases affecting the anterior segment of the eye. Nonetheless, the ocular bioavailability for deeper ocular tissues is very low. Different routes of administration, such as intravitreal injections, periocular injections, and systemic administration, have been used to deliver drugs into the posterior segment ocular tissues. However, the presence of blood-retinal barriers (BRBs) makes systemic administration an impractical approach, whereas the drug delivery with the periocular administration route is compromised by ocular static and dynamic barriers. On the other hand, intravitreal injection, the most common and widely recommended route for drug administration to treat posterior ocular diseases, is related to several side effects such as endophthalmitis, hemorrhage, retinal detachment, and poor patient tolerance. Diverse strategies to overcome ocular barriers have been explored for topical drop formulations in order to deliver drugs into the posterior segment ocular tissues. In this chapter, we will review the promising topical nanocarriers for drug delivery into the posterior segment of the eye, emphasizing the use of liposomes for topical ophthalmic formulations targeting the vitreous cavity and the retina

Uncovering a new group of T Tauri stars in the Taurus-Auriga molecular complex from Gaia and GALEX data

In this work, we examine the list of 63 candidates to T Tauri star (TTS) in the TAMC identified by their ultraviolet (UV) and infrared colours (IR) measured from data obtained by the Galaxy Evolution Explorer all sky survey (GALEX-AIS) and the Two Microns All Sky Survey (2MASS), respectively. The objective of this work is twofold: evaluate whether they are pre-main sequence (PMS) stars and evaluate the goodness of the UV-IR colour-colour diagram to detect PMS stars in wide-fields. The astrometric properties of these sources have been retrieved from the Gaia DR3 catalogue and used to evaluate their membership probability. Several classification algorithms have been tested to search for the kinematical groups but the final classification has been made with k-means++ algorithms. Membership probability has been evaluated by applying Logistic Regression. In addition, spectroscopic information available in the archive of the Large Sky Area Multi Object Fiber Spectroscopic Telescope has been used to ascertain their PMS nature when available. About 20% of the candidates share the kinematics of the TAMC members. Among them, HD 281691 is a G8-type field star located in front of the cloud and HO Aur is likely a halo star given the very low metallicity provided by Gaia. The rest are three known PMS stars (HD 30171, V600 Aur and J04590305+3003004), two previously unknown accreting M-type stars (J04510713+1708468 and J05240794+2542438) and, five additional sources, which are very likely PMS stars. Most of these new sources are concentrated at low galactic latitudes over the Auriga-Perseus region.Comment: accepted by A&
