Estudio e implantación de un sistema de iluminación tipo Led en el Museo Casa Lis de Salamanca

El Museo Art Nouveau y Art Déco Casa Lis de Salamanca implantará un proyecto de mejora de eficiencia energética con el fin de reducir su consumo de luz y mejorar los sistemas de conservación y exposición de sus colecciones. Para ello, se sustituirán las actuales luminarias de la Casa Lis (halógenos, incandescentes y halogenuros, entre otros) por iluminación LED, intervención que supondrá un gran ahorro de costes, así como la notable mejora en la exhibición y conservación de las piezas. Todo ello se llevará a cabo bajo unos parámetros máximos recomendados con el fin de buscar un equilibrio entre las necesidades de conservación de las obras exhibidas y el confort visual del museo. El ahorro que se producirá en el gasto de luz en la Casa Lis en los próximos años permitirá sufragar la mayor parte del coste del proyecto. Dicho proyecto se llevará a cabo a través de la empresa ECOLED DESARROLLOS, la cual presta Servicios de Ingeniería orientada al sector energético, más concretamente, en el ámbito de la eficiencia energética y cuyo compromiso con la sostenibilidad tiene como objetivo reducir la huella climática de sus clientes. Se trata de una de las empresas pioneras en España en la aplicación de la tecnología LED para dar todo tipo de soluciones, siendo expertos en esta materia.Ingeniería Técnica en Electrónic

Detecting fractures and monitoring hydraulic fracturing processes at the first EGS Collab testbed using borehole DAS ambient noise

Enhanced geothermal systems (EGS) require cost-effective monitoring of fracture networks. We validate the capability of using borehole distributed acoustic sensing (DAS) ambient noise for fracture monitoring using core photos and core logs. The EGS Collab project has conducted 10 m scale field experiments of hydraulic fracture stimulation using 50-60 m deep experimental wells at the Sanford Underground Research Facility (SURF) in Lead, South Dakota. The first EGS Collab testbed is located at 1616.67 m (4850 ft) depth at SURF and consists of one injection well, one production well, and six monitoring wells. All wells are drilled subhorizontally from an access tunnel called a drift. The project uses a single continuous fiber-optic cable installed sequentially in the six monitoring wells to record DAS data for monitoring hydraulic fracturing during stimulation. We analyze 60 s time records of the borehole DAS ambient noise data and compute the noise root-mean-square (rms) amplitude on each channel (points along the fiber cable) to obtain DAS ambient noise rms amplitude depth profiles along the monitoring wellbore. Our noise rms amplitude profiles indicate amplitude peaks at distinct depths. We compare the DAS noise rms amplitude profiles with borehole core photos and core logs and find that the DAS noise rms amplitude peaks correspond to the locations of fractures or lithologic changes indicated in the core photos or core logs. We then compute the hourly DAS noise rms amplitude profiles in two monitoring wells during three stimulation cycles in 72 h and find that the DAS noise rms amplitude profiles vary with time, indicating the fracture opening/growth or closing during the hydraulic stimulation. Our results demonstrate that borehole DAS passive ambient noise can be used to detect fractures and monitor fracturing processes in EGS reservoirs

The relationship between sensory sensitivity and autistic traits in the general population.

Individuals with Autism Spectrum Disorders (ASDs) tend to have sensory processing difficulties (Baranek et al. in J Child Psychol Psychiatry 47:591–601, 2006). These difficulties include over- and under-responsiveness to sensory stimuli, and problems modulating sensory input (Ben-Sasson et al. in J Autism Dev Disorders 39:1–11, 2009). As those with ASD exist at the extreme end of a continuum of autistic traits that is also evident in the general population, we investigated the link between ASD and sensory sensitivity in the general population by administering two questionnaires online to 212 adult participants. Results showed a highly significant positive correlation (r = .775, p < .001) between number of autistic traits and the frequency of sensory processing problems. These data suggest a strong link between sensory processing and autistic traits in the general population, which in turn potentially implicates sensory processing problems in social interaction difficulties

Direct oral anticoagulants in patients with hypertrophic cardiomyopathy and atrial fibrillation.

Background: Chronic anticoagulation with vitamin K antagonists (VKAs) is recommended in patients with hypertrophic cardiomyopathy (HCM) and atrial fibrillation (AF). Direct oral anticoagulants (NOACs) are an alternative to VKAs but there are limited data to support their use in HCM. We sought to describe the pattern of use, thromboembolic events, bleeding and quality of life in patients with HCM and AF treated with NOACs. Methods: Data from patients treated with NOACs (n=99) and VKA (n=433) at 9 inherited cardiac diseases units were retrospectively collected. Annual rates of embolic events, serious bleeding and death were analysed and compared. Quality of life and treatment satisfaction were evaluated with SF-36 and SAFUCA questionnaires in 80 NOAC-treated and 57 VKA-treated patients. Results: After median follow-up of 63 months (IQR:26–109), thromboembolic events (TIA/stroke and peripheral embolism) occurred in 10% of patients on oral anticoagulation. Major/clinically relevant bleeding occurred in 3.8% and the global mortality rate was 23.3%. Thromboembolic event rate was 0.62 per 100 patient-years in the NOAC group vs. 1.59 in the VKA group [subhazard ratio (SHR) 0.32;95%CI:0.04– 2.45;p=0.27]. Major/clinically relevant bleeding occurred in 0.62 per 100 person-years in the NOAC group vs. 0.60 in the VKA group (SHR 1.28;95%CI 0.18–9.30;p=0.85). Quality of life scores were similar in both groups; however, NOAC-treated patients achieved higher scores in the SAFUCA. Conclusions: HCM patients with AF on NOACs showed similar embolic and bleeding rates to those on VKA. Although quality of life was similar in both groups, the NOAC group reported higher treatment satisfaction.pre-print929 K

Verbal thinking and inner speech use in autism spectrum disorder

The extent to which cognition is verbally mediated in neurotypical individuals is the subject of debate in cognitive neuropsychology, as well as philosophy and psychology. Studying “verbal thinking” in developmental/neuropsychological disorders provides a valuable opportunity to inform theory building, as well as clinical practice. In this paper, we provide a comprehensive, critical review of such studies among individuals with autism spectrum disorder (ASD). ASD involves severe social-communication deficits and limitations in cognitive/behavioural flexibility. The prevailing view in the field is that neither cognition nor behaviour is mediated verbally in ASD, and that this contributes to diagnostic features. However, our review suggests that, on the contrary, most studies to date actually find that among people with ASD cognitive task performance is either a) mediated verbally in a typical fashion, or b) not mediated verbally, but at no obvious cost to overall task performance. Overall though, these studies have methodological limitations and thus clear-cut conclusions are not possible at this stage. The aim of the review is to take stock of existing empirical findings, as well as to help develop the directions for future research that will resolve the many outstanding issues in this field

Comparative Fourier Transform Infrared Investigation of Oltu-Stone (Natural Carbon Black) and Jet

Fourier transform infrared (FT-IR) investigation of Oltu-stone (natural carbon black) and jet revealed several differences between these carbonaceous materials. The band peaking at about 1000cm(-1) is the first important difference: while the band in the jet spectra appears as one sharp peak at about 1001cm(-1), the similar band in the Oltu-stone spectra is shifted to about 1026cm(-1) with a broad shoulder toward high frequency. Even though the assignment of the shifted band is at present controversial, it may be attributed to carbon-oxygen stretching mode. Second, the doublet bands at about 2912 and 2843cm(-1) are much more intense in the jet spectra then in the Oltu-stone spectra. They are confidently attributed to aliphatic C-H stretching mode. Finally, the broad water band on setting at about 3750cm(-1) is maturated in Oltu-stone, and it is much more evident than in that of jet. Therefore, FT-IR appears as a favorable identification method for these kinds of carbonaceous materials

Cathodoluminescence (CL) features of the Anatolian agates, hydrothermally deposited in different volcanic hosts from Turkey

Two different types of multi-colored gem-quality agate samples were investigated. They are both found in the same area in the Cubuk-Ankara region of Turkey although the first group is morphologically and geologically distinct from the second, being nodular-shaped agates occurring in cavity-spaces of a rhyolite host rock with an acidic character. They generally do not have any macroscopic inclusions, but the second group of rather block-shaped agates occurs in the fracture-spaces of an andesite host rock with a more neutral character, i.e. of lower free silica content, and they may display pseudomorphic bar-like macroscopic inclusions
