Analysis of the Barriers to the Uptake of R&D Results in the Power Sector

Power grid vulnerabilities are European wide problems, they cannot be solved individually but require a coordinated European effort. GRID aims at establishing a roadmap for collaborative R&D on power grid security, also based on exchange of information about national, regional and European research projects. Collaborative research programmes might benefit from a mutual exchange of approaches, experiences, and results. However, cross fertilisation may be hampered by existing barriers of an institutional, socio-economic and technical nature. This report investigates barriers to exploitation of national research results in a European context.JRC.G.6-Sensors, radar technologies and cybersecurit

First record of Latonia gigantea (Anura, Alytidae) from the Iberian Peninsula

The single extant species of the anuran genus Latonia lives in Israel, but in the fossil record the genus is known mainly from Europe, spanning from the Oligocene to the early Pleistocene. Here we describe new remains of Latonia from the early to late Miocene of the Vallès-Penedès Basin (NE Iberian Peninsula), coming from the following localities: Sant Mamet (MN4), Sant Quirze and Trinxera del Ferrocarril (MN7+8), and Castell de Barberà, Can Poncic 1 and Can Llobateres 1 (MN9). Fossils from the late Aragonian and early Vallesian are attributed to Latonia gigantea mainly because of the morphology of the ornamentation that covers the maxillae. In turn, an ilium from Sant Mamet is not diagnostic at the specific level and is assigned only to the genus Latonia. The newly reported remains represent the first record of L. gigantea in the Iberian Peninsula, where Latonia was previously known by a single report of Latonia cf. ragei from Navarrete del Río (MN2) and remains from other localities unassigned to species. Moreover, the Vallès-Penedès remains represent one of the southernmost records of the species known thus far. The presence of Latonia in these localities confirms the humid and warm environment suggested by the recorded mammal fauna

Optical properties of carbon nanostructures produced by laser irradiation on chemically modified multi-walledcarbon nanotubes

Apoyo a la Red Temática de Colaboración Académica: Desarrollo de Materiales Compuestos con propiedades Ópticas, Eléctricas , Magnéticas y sus aplicacionesThis research focused on the nanosecond(Nd:YAG-1064 nm) laser pulse effect on the optical and morphological properties of chemically modified multi-walled carbon nanotubes(MWCNT).Two sus- pensions of MWCNT in tetrahydrofuran (THF) were prepared,one was submitted to laser pulses for 10 min while the other (blank) was only mechanically homogenized during the same time. Following the laser irradiation, the suspension acquired a yellow-amber color,in contrast to the black translucent appearance of the blank. UV-vis spectroscopy confirmed this observation, showing the blank a higher absorption. Additionally, photoluminescence measurements exhibited a broad blue-green emission band both in the blank and irradiated suspension when excited at 369 nm, showing the blank a lower intensity. However, a modification in the excitation wave length produced a violet to green tuningin the irradiated suspension, which did not occurin the blank. Lastly, the electron microscopy analysis of the treated nanotubes showed the abundant formation of amorphous carbon, nanocages, and nanotube unzipping, exhibiting the intense surface modification produced by the laser pulse. Nanotube surface modification and the coexistence with the new carbon nanostructures were considered as the conductive conditions for optical properties modification.PROME

In search of hepatitis E virus infection in wild boar and cattle from Argentina

Hepatitis E virus (HEV) is a pathogen with zoonotic potential that affects domestic pigs, wild boar Sus scrofa, and humans, among other species. The HEV has been reported in wild boar from Argentina and Uruguay, but knowledge about the epidemiology of this virus is still very scarce in this region. The objective of this study was to evaluate the circulation of HEV in wild boar and cattle from Argentina through serological (ELISA) and molecular (PCR) analyses. All samples were negative. However, we stress the importance of reporting negative cases since these represent key inputs in future research and risk analysis, mainly in association with the potential for virus transmission between wild boar and susceptible native species.El virus de hepatitis E (VHE) es un patógeno con potencial zoonótico que afecta al cerdo doméstico, al jabalí Sus scrofa y al ser humano, entre otras especies. El VHE ha sido reportado en jabalíes de Argentina y Uruguay, pero el conocimiento acerca de la epidemiología de este virus es aún muy escaso en la región. El objetivo del presente estudio fue evaluar la circulación del VHE es poblaciones de jabalí y ganado vacuno en Argentina, a través de análisis serológicos (ELISA) y moleculares (PCR).

Revision of Varanus marathonensis (Squamata, Varanidae) based on historical and new material: morphology, systematics, and paleobiogeography of the European monitor lizards

Monitor lizards (genus Varanus) inhabited Europe at least from the early Miocene to the Pleistocene. Their fossil record is limited to about 40 localities that have provided mostly isolated vertebrae. Due to the poor diagnostic value of these fossils, it was recently claimed that all the European species described prior to the 21st century are not taxonomically valid and a new species, Varanus amnhophilis, was erected on the basis of fragmentary material including cranial elements, from the late Miocene of Samos (Greece). We re-examined the type material of Varanus marathonensis Weithofer, 1888, based on material from the late Miocene of Pikermi (Greece), and concluded that it is a valid, diagnosable species. Previously unpublished Iberian material from the Aragonian (middle Miocene) of Abocador de Can Mata (Vallès-Penedès Basin, Barcelona) and the Vallesian (late Miocene) of Batallones (Madrid Basin) is clearly referable to the same species on a morphological basis, further enabling to provide an emended diagnosis for this species. Varanus amnhophilis appears to be a junior subjective synonym of V. marathonensis. On the basis of the most complete fossil Varanus skeleton ever described, it has been possible to further resolve the internal phylogeny of this genus by cladistically analyzing 80 taxa coded for 495 morphological and 5729 molecular characters. Varanus marathonensis was a large-sized species distributed at relatively low latitudes in both southwestern and southeastern Europe from at least MN7+8 to MN12. Our cladistic analysis nests V. marathonensis into an eastern clade of Varanus instead of the African clade comprising Varanus griseus, to which it had been related in the past. At least two different Varanus lineages were present in Europe during the Neogene, represented by Varanus mokrensis (early Miocene) and V. marathonensis (middle to late Miocene), respectively

Metatypical basal cell carcinoma: a clinical review

Background. Metatypical cell carcinoma can be considered as a new entity of skin cancer, being an intermediate typology between basal cell carcinomas and squamous cell carcinomas. The behaviour of the metatypical cell carcinoma lies between these two varieties of skin cancer. It is difficult to perform a differential diagnosis based on morphological and clinical features - therefore it is only possible by accurate histology. Methods. The authors have retrospectively analysed clinical records of 240 patients who were affected by metatypical skin cancer and who were treated by surgery, radiotherapy and chemotherapy. Results. MTC affected more males than females (62.5% vs 37.5%) than males. The most affected site was the cervicofacial area, 71.7%; then the trunk, 10%; the limbs, 9.6%; the scalp 3.7%; and other regions 5%. A recurrence occurred in 24 cases (10%), mainly in head and neck area. Conclusion. In this manuscript, the authors have emphasised the importance of conducting a differential diagnosis, and the importance of the specific treatment for metatypical skin cancer, even though more clinical studies and long-term follow-ups are required before establishing specific guidelines. © 2008 Tarallo et al; licensee BioMed Central Ltd

Análisis bibliométrico sobre la investigación ambiental en México

El hombre en su creciente necesidad de comprender y explicar su presencia en el medio que lo rodea y los procesos en los cuales se involucra se ha visto obligado a estudiar el ambiente bajo diversos enfoques con la finalidad de conocer y comprender mejor esos procesos. La cuestión ambiental emerge como una problemática de carácter interdisciplinario, que requiere la colaboración de diversas disciplinas del campo de las ciencias naturales y sociales; sin embargo, hasta ahora han predominado los enfoques provenientes de las ciencias naturales y las soluciones de carácter técnico

Nearly automated analysis of coronary Doppler flow velocity from transthoracic ultrasound images: validation with manual tracings

Coronary flow velocity reserve is obtained by manual tracings of transthoracic coronary Doppler flow velocity profiles as the ratio of stress versus baseline diastolic peak velocities. This approach introduces subjectivity in the measurements and limits the information which could be exploited from the Doppler velocity profile. Accordingly, our goals were to develop a technique for nearly automated detection of Doppler coronary flow velocity profile, and automatically compute both conventional and additional amplitude, derivative and temporal parameters, and validate it with manual tracings. A total of 100 patients (17 normals, 15 patients with severe coronary stenosis, 41 with connective tissue disease and 27 with diabetes mellitus) were studied. Linear correlation and Bland-Altman analyses showed that the proposed method was highly accurate and repeatable compared to the manual measurements. Comparison between groups evidenced significant differences in some of the automated parameters, thus representing potentially additional indices useful for the noninvasive diagnosis of microcirculatory or coronary artery disease
