Energy harvesting from vehicular traffic over speed bumps: A review

Energy used by vehicles to slow down in areas of limited speed is wasted. A traffic energy-harvesting device (TEHD) is capable of harvesting vehicle energy when passing over a speed bump. This paper presents a classification of the different technologies used in the existing TEHDs. Moreover, an estimation of the energy that could be harvested with the different technologies and their cost has been elaborated. The energy recovered with these devices could be used for marking and lighting of roads in urban areas, making transportation infrastructures more sustainable and environmentally friendly

Enfermedades y fisiopatías que afectan a la calidad del ajo en postcosecha

Las enfermedades y fisiopatías que afectan al ajo pueden llegar a ocasionar importantes pérdidas en postcosecha, de vital importancia cuando el producto se destina a la exportación a mercados que cada día son más exigentes. En 2008, distintos agricultores de varios municipios de Castilla y León detectaron bulbos de ajo que presentaban síntomas de podredumbre húmeda durante el almacenamiento. Posteriormente, en el año 2009, esta misma podredumbre se observó también en las provincias de Albacete y Cuenca y en muestras procedentes de Córdoba. Hasta la fecha se ha identificado a Fusarium proliferatum como el agente causal de la podredumbre del diente

Influencia del tratamiento químico con cloroformo/metanol en el comportamiento elástico del pericardio de ternera utilizado en la construcción de bioprótesis cardiacas

Se estudia el comportamiento mecánico del pericardio de ternera utilizado en la construcción de bioprótesis cardiacas cuando se trata químicamente cloroformo/metanol (CM) comparándolo con tratamiento estándar con glutaraldehído.(G). Se ensayan a tracción hasta rotura 40 probetas, veinte con cada tratamiento y de estas el 50% suturadas en su parte central con seda 4/0.La perdida de resistencia media a la rotura de las probetas suturadas fue de alrededor de 6 MPa sin encontrar diferencias entre el tipo de tratamiento utilizado. No obstante en el análisis de las curvas promedio estrés/deformación para valores de estrés a tracción inferiores a 2.5 MPa, apenas encontramos diferencias entre las series suturadas y no suturadas tratadas con cloroformo/metanol anulando parcialmente el efecto deletéreo de la sutura en ese rango de estrés que incluye el estrés estimado de trabajo, de 0.25MPa.El tratamiento con cloroformo/metanol podría, además de retrasar los procesos de calcificación del pericardio, mejorar el comportamiento elástico de las probetas suturadas disminuyendo la interacción con la sutura. Ensayos de fatiga real con este tratamiento químico deberán ser realizados para verificar esta hipótesis.Peer Reviewe

The nuclear and extended infrared emission of the Seyfert galaxy NGC 2992 and the interacting system Arp 245

We present subarcsecond resolution infrared (IR) imaging and mid-IR spectroscopic observations of the Seyfert 1.9 galaxy NGC 2992, obtained with the Gemini North Telescope and the Gran Telescopio CANARIAS (GTC). The N-band image reveals faint extended emission out to ~3 kpc, and the PAH features detected in the GTC/CanariCam 7.5-13 micron spectrum indicate that the bulk of this extended emission is dust heated by star formation. We also report arcsecond resolution MIR and far-IR imaging of the interacting system Arp 245, taken with the Spitzer Space Telescope and the Herschel Space Observatory. Using these data, we obtain nuclear fluxes using different methods and find that we can only recover the nuclear fluxes obtained from the subarcsecond data at 20-25 micron, where the AGN emission dominates. We fitted the nuclear IR spectral energy distribution of NGC 2992, including the GTC/CanariCam nuclear spectrum (~50 pc), with clumpy torus models. We then used the best-fitting torus model to decompose the Spitzer/IRS 5-30 spectrum (~630 pc) in AGN and starburst components, using different starburst templates. We find that, whereas at shorter mid-IR wavelengths the starburst component dominates (64% at 6 micron), the AGN component reaches 90% at 20 micron. We finally obtained dust masses, temperatures and star formation rates for the different components of the Arp 245 system and find similar values for NGC 2992 and NGC 2993. These measurements are within those reported for other interacting systems in the first stages of the interaction.Comment: 20 pages, 12 figures, accepted by MNRA

Physical and chemical characterization of cerium(IV) oxide nanoparticles

Chemical composition, size and structure of the nanoparticle are required to describe nanoceria. Nanoparticles of similar size and Ce(III) content might exhibit different chemical behaviour due to their differences in structure. A simple and direct procedure based on affordable techniques for all the laboratories is presented in this paper. The combination of Raman and UV-vis spectroscopy and particle impact coulometry (PIC) allows the characterization of nanoceria of small size from 4 to 65 nm at a concentration from micromolar to nanomolar, a concentration range suitable for the analysis of lab-prepared or commercial nanoparticle suspensions, but too high for most analytical purposes aimed at nanoparticle monitoring. While the PIC limits of size detection are too high to observe small nanoparticles unless catalytic amplification is used, the method provides a simple means to study aggregation of nanoparticles in the media they are needed to be dispersed for each application. Raman spectroscopy provided information about structure of the nanoparticle, and UV-vis about their chemical behaviour against some common reducing and oxidizing agents

Testing M2T/T2M Transformations

Presentado en: 16th International Conference on Model Driven Engineering Languages and Systems (MODELS 2013). Del 29 de septiembre al 4 de octubre. Miami, EEUU.Testing model-to-model (M2M) transformations is becoming a prominent topic in the current Model-driven Engineering landscape. Current approaches for transformation testing, however, assume having explicit model representations for the input domain and for the output domain of the transformation. This excludes other important transformation kinds, such as model-to-text (M2T) and text-to-model (T2M) transformations, from being properly tested since adequate model representations are missing either for the input domain or for the output domain. The contribution of this paper to overcome this gap is extending Tracts, a M2M transformation testing approach, for M2T/T2M transformation testing. The main mechanism we employ for reusing Tracts is to represent text within a generic metamodel. By this, we transform the M2T/T2M transformation specification problems into equivalent M2M transformation specification problems. We demonstrate the applicability of the approach by two examples and present how the approach is implemented for the Eclipse Modeling Framework (EMF). Finally, we apply the approach to evaluate code generation capabilities of several existing UML tools.Universidad de Málaga. Campus de Excelencia Internacional Andalucía Tech. Proyecto TIN2011-2379

Ectopic ACTH syndrome in a dog with a mesenteric neuroendocrine tumour: a case report

Ectopic ACTH secretion is provoked by extra-pituitary tumours that secrete ACTH, constituting an infrequent type of Cushing Syndrome in the dog. Neuroendocrine tumours (NET) are characterised by the synthesis of peptides with hormone activity. A dog with clinical diagnosis of Cushing?s syndrome and presenting an abdominal tumour located in the area of the left adrenal gland was sent to the hospital. Cortisol was not inhibited at four and eight hours after the application of low-dose dexamethasone and the cortisol/creatinine ratio was elevated (93 × 10-6, reference values < 10 × 10?6). Plasma ACTH measurements were high (28.6 pmol/l, reference values 5.5?14.3 pmol/l). On computed tomography, the tumour was found in the meso-epigastrium, with both adrenal glands hyperplasic and no alteration of the pituitary image. The tumour was located between the two layers of the meso-colon and was removed using laparoscopy. After surgery, ACTH concentrations became normal and clinical signs remitted. The histopathological diagnosis was NET, with positive ACTH immunostaining.Fil: Castillo, V. A.. Universidad de Buenos Aires. Facultad de Ciencias Veterinarias; ArgentinaFil: Pessina, P. P..
