Thermal assessment of ambient pressure dried silica aerogel composite boards at laboratory and field scale

In the context of increasing energy costs and the need for global reduction of CO2 emissions, the development of superinsulation materials for the construction sector allows the design of low-energy buildings. Since still being in an experimental or at early-commercial stage, R&D of these materials focused on its final application is required, to accelerate access to the market for renovation of the building stock where space is a critical metric. In this paper, the experimental assessment of the thermal performance of a novel ambient pressure dried silica aerogel based composite is presented. In order to provide assessments at both, material and system levels, stress-strain tests, hot plate measurements, as well as full scale tests under realistic boundary conditions were conducted. The overall results are that this material provides good insulation properties (thermal conductivity in the range of 0.015–0.018 W/mK), along with sufficient mechanical properties, and allows for the creation of superinsulating assemblies even at small wall thickness.European Commission's FP

Novel circular economy business model of high-added value products for energy efficiency: from C&DW to aerogels

Here, we present a novel closed-loop circular economy model of a high-performance building insulation material from silica containing C&DW materials to silica aerogels with λ≈0.015 W/mK. In the present model, the benefit comes with the use of massive construction waste to a silica precursor and thereby aerogel production guaranteeing at least 40% product cost reduction and 40% reduction in energy consumption in real construction environment

What mechanism of niche segregation allows the coexistence of sympatric sibling rhinolophid bats?

Introduction: Our purpose was to assess how pairs of sibling horseshoe bats coexists when their morphology and echolocation are almost identical. We collected data on echolocation, wing morphology, diet, and habitat use of sympatric Rhinolophus mehelyi and R. euryale. We compared our results with literature data collected in allopatry with similar protocols and at the same time of the year (breeding season). Results:Echolocation frequencies recorded in sympatry for R. mehelyi (mean = 106.8 kHz) and R. euryale (105.1 kHz) were similar to those reported in allopatry (R. mehelyi 105–111 kHz; R. euryale 101–109 kHz). Wing parameters were larger in R. mehelyi than R. euryale for both sympatric and allopatric conditions. Moths constitute the bulk of the diet of both species in sympatry and allopatry, with minor variation in the amounts of other prey. There were no inter-specific differences in the use of foraging habitats in allopatry in terms of structural complexity, however we found inter-specific differences between sympatric populations: R. mehelyi foraged in less complex habitats. The subtle inter-specific differences in echolocation frequency seems to be unlikely to facilitate dietary niche partitioning; overall divergences observed in diet may be explained as a consequence of differential prey availability among foraging habitats. Inter-specific differences in the use of foraging habitats in sympatry seems to be the main dimension for niche partitioning between R. mehelyi and R. euryale, probably due to letter differences in wing morphology. Conclusions: Coexistence between sympatric sibling horseshoe bats is likely allowed by a displacement in spatial niche dimension, presumably due to the wing morphology of each species, and shifts the niche domains that minimise competition. Effective measures for conservation of sibling/similar horseshoe bats should guarantee structural diversity of foraging habitats

One-hundred aortic valve replacements in octogenarians: Outcomes and risk factors for early mortality

Background and aim of the study: Today, ageing of the western population is causing aortic valve surgery to be performed in elderly patients with increasing frequency. The study aim was to evaluate surgical outcome in octogenarian patients undergoing aortic valve replacement (AVR). Methods: A total of 100 patients (mean age 82.1 +/- 2.7 years; range: 80-95 years) who underwent AVR over a three-year period was reviewed. Concomitant coronary artery bypass grafting was performed in 34% of cases, and a bioprosthesis was implanted in 80%. The mean logistic EuroSCORE was 13.3%. Results: Operative mortality was 8.0%. In multivariate analysis, a logistic EuroSCORE >= 13.5% (p = 0.02), cross-clamp time >= 75 min (p = 0.02) and postoperative acute renal failure were predictors for in-hospital mortality. Follow up was 100% complete; the mean follow up period was 10.6 months. At one year after surgery, the actuarial survival rate of those patients who survived surgery was 86.1%. Postoperative dyspnea at one month (p = 0.004) was the only predictor of short-term mortality. Conclusion: Age in itself should not contraindicate surgery, and healthcare systems should be prepared to accommodate elderly patients who may require special resources

Video-assisted mitral surgery through a micro-access: A safe and reliable reality in the current era

Background and aim of the study: Minimally invasive mitral valve surgery was introduced into clinical practice during the mid 1990s. The clinical benefits of the technique, namely a reduction of surgical trauma, increased patient comfort and shorter hospital stay, are achieved by using a video-assisted, mini-thoracotomy approach rather than a standard median sternotomy. Herein is described the authors' experience with video-assisted mitral surgery through a micro-access. Methods: Between September 2003 and September 2006, 100 patients (mean age 65.7 years; range: 16-84 years; 29 aged >75 years) underwent video-assisted port-access mitral valve surgery through a 4- to 6-cm anterior mini-thoracotomy. Mitral valve repair was carried out in 36 patients (36%) and mitral valve replacement (MVR) in 64 (64%) for degenerative (n = 54), rheumatic (n = 44), functional (n = 1) or infective disease (n = 1). Redo procedures were performed in 14 patients. Results: Peripheral extra-thoracic cardiopulmonary bypass (CPB) was used in all cases, and Endoclamp occlusion of the ascending aorta in 94%. The median intensive care unit and hospital stays were 20.0 +/- 30.8 h and 7.0 +/- 5.9 days, respectively. Hospital mortality was 4% (n = 4). No patient required conversion to sternotomy. Five patients (5%) underwent minimally invasive surgical revision for bleeding, and one patient (1%) had an early reoperation for MVR during the immediate postoperative course due to failure of a mitral valve repair. There were no perioperative myocardial infarctions, permanent strokes, major vascular complications, or peripheral ischemic events. Among the patients, 63% had no complications at all during the postoperative course, and no wound infections were observed. Conclusion: Video-assisted mitral surgery through a micro-access may be performed safely, at low risk of morbidity and mortality, and with results and quality standards similar to those reported for a sternotomy approach. Of note, older patients may be successfully treated using this technique
