Metal–Organic Frameworks (MOFs) Containing Adsorbents for Carbon Capture
2022
This research was funded by the European Regional Development Fund project “Innovation of the waste‐to‐energy concept for the low carbon economy: development of novel carbon capture technology for thermochemical processing of municipal solid waste (carbon capture and storage from waste—CCSW)”, grant number 1.1.1.1/19/A/013.
Improving diagnostic accuracy of MDCT coronary angiography in patients with mild heart rhythm irregularities using ECG editing
2006
OBJECTIVE. The objective of our study was to compare diagnostic accuracy of MDCT coronary angiography in a population of patients with mild heart rhythm irregularities before and after editing the ECG. SUBJECTS AND METHODS. Thirty-eight patients who underwent MDCT coronary angiography and conventional coronary angiography were enrolled in the study. The inclusion criterion was the presence of mild heart rhythm irregularities (i.e., premature beats; atrial fibrillation; mistriggering; or low heart rate, defined as 40 beats per minute or less) during the scan. All patients underwent MDCT with the following parameters: 16 detectors; collimation, 0.75 mm; gantry rotation time, 375 msec; 120 kV;…
Dye-tracer technique for rill flows by velocity profile measurements
2020
Abstract Water flow on hillslope soil surface supplies energy which is required to detach soil particles, to transport and deposit sediments, therefore flow velocity is a key variable related to hillslope hydrodinamics of soil erosion processes. Among the different methods available for measuring velocity of shallow interrill and rill flow, the trace technique is widely used. Trace technique is applied by adding a material (salt, magnetic material, water isotope, floating object) and then measuring the speed of the material to travel a known distance from the injection point. When flow velocity is measured using a dye-tracing method, the mean velocity is calculated by multiplying the measur…
Flume experiments for assessing the dye-tracing technique in rill flows
2021
Abstract Flow velocity controls hillslope soil erosion and is a key hydrodynamic variable involved in sediment transport and deposition processes. The dye-tracer technique is one of the most applied methods for measuring velocity of shallow interrill and rill flow. The technique is based on the injection of a tracer in a specific point and the measurement of its speed to travel the known distance from the injection point to a given channel section. The dye-tracer technique requires that the measured surface flow velocity has to be corrected to obtain the mean flow velocity using a correction factor which is generally empirically deduced. The technique has two sources of uncertainties: i) th…
Planktonic foraminifera in ODP Hole 160-963A
2006
New faunal and floral records from Ocean Drilling Project Hole 963A, resolved at ?80-year spacing, provide evidence of suborbital scale climate variability in the central Mediterranean Sea throughout Marine Isotope Stage (MIS) 5. Cold events in the central Mediterranean Sea, indicated by low abundances of warm species and high abundances of cold species, are also evident in a planktonic foraminifera paleoclimatic curve. They have been linked to NGRIP Greenland ice core “C” events and appear correlative with similar sub-millennial climate fluctuations identified in the North Atlantic region and in the Alboran Basin (Westernmost Mediterranean). Low-resolution benthic and planktonic Oxygen Iso…
Inelastic and quasi-elastic light scattering in (NaCN)1?x(KCN)x quadrupolar glasses
1990
The elastic constantsc11 andc44, and the attenuation of longitudinal phonons along (100)-direction in (NaCN)1−x(KCN)x mixed crystals have been determined by brillouin spectroscopy in the temperature range fromT=10K−300K. Minima inc44 (T) which determine the freezing tempratureTF in these orientational glasses appear at lower temperatures compared to neutron scattering results. The coupling of molecular reorientations to longitudinal phonons in NaCN-rich smaples shows up in dispersion effects inc11 (T) and the appearence of a dynamical central peak nearTF.

Santiago Carrillo 1971. Políticas en transición y transferencia carismática
2015
Resumen : En junio de 1971, el PCE organizo un gran mitin politico en las cercanias de Paris. En el se presentaban ante una masa de militantes, simpatizantes y antifranquistas dos lideres, Dolores Ibarruri (Pasionaria) y Santiago Carrillo, que habian desempenado un importante papel en la historia de Espana y que se preparaban para hacerlo en el futuro postfranquista. El encuentro recibio una notable cobertura a traves de la prensa y fue ampliamente fotografiado. Un film fue rodado y montado por la Comision de Cine de Barcelona en colaboracion con el colectivo frances Dynadia . El presente texto analiza las distintas dimensiones de este encuentro en relacion con la tactica del partido, la lu…
Moritz Hauptmann in München. Hochschuldidaktik im 19. Jahrhundert
2014
Dass Moritz Hauptmanns Buch Die Natur der Harmonik und der Metrik zur Basis institutionalisierter musiktheoretischer Unterweisung wurde, wie an der Koniglich bayerischen Musikschule in Munchen nachweisbar, mag angesichts des hohen Abstraktionsgrads dieser Schrift verwundern. Besonders der Unterricht in der ersten Dekade an der Musikschule kann als einzigartiges Exempel der systematischen Anwendung Hauptmanns in der Lehre verstanden werden. Der Beitrag erortert die Bedeutung der Schrift Hauptmanns fur die Lehre der wichtigsten Fachvertreter nach Grundung der Musikschule (Peter Cornelius und Josef Gabriel Rheinberger), sowie – als Verfallsgeschichte – in der Zeit nach Cornelius’ fruhem Tod un…
