Liquid intrusion and alternative methods for the characterization of macroporous materials (IUPAC Technical Report)

2011

This document deals with the characterization of porous materials having pore widths in the macropore range of 50 nm to 500 μm. In recent years, the development of advanced adsorbents and catalysts (e.g., monoliths having hierarchical pore networks) has brought about a renewed interest in macropore structures. Mercury intrusion–extrusion porosimetry is a well-established method, which is at present the most widely used for determining the macropore size distribution. However, because of the reservations raised by the use of mercury, it is now evident that the principles involved in the application of mercury porosimetry require reappraisal and that alternative methods are worth being listed…

Interactions, spillovers de connaissance et croissance des villes européennes. Faut-il préférer la géographie, le climat institutionnel ou les réseau…

2013

Knowledge spillovers within urban economies are also sources of spillovers between cities. We examine how knowledge spillovers influenced the economic growth of 82 European metropolises over the 1990-2005 period. We model knowledge spillovers between cities on the basis of five specific interaction patterns based on geography, networks of multinational firms in advanced services, institutional climate and two combinations of these factors. Spatial models are estimated to detail the effects of growth factors in terms of spillovers and externalities. We show that spillovers are local rather than global and that interactions among cities accelerate the convergence process based on gross value …

A non-parametric segmentation methodology for oral videocapillaroscopic images

2014

We aim to describe a new non-parametric methodology to support the clinician during the diagnostic process of oral videocapillaroscopy to evaluate peripheral microcirculation. Our methodology, mainly based on wavelet analysis and mathematical morphology to preprocess the images, segments them by minimizing the within-class luminosity variance of both capillaries and background. Experiments were carried out on a set of real microphotographs to validate this approach versus handmade segmentations provided by physicians. By using a leave-one-patient-out approach, we pointed out that our methodology is robust, according to precision-recall criteria (average precision and recall are equal to 0.9…

The carrier-loaded helium-jet transport method

1974

Abstract The suitability of commercial helium loaded with small amounts of different gases or vapors for the transport of radioactive reaction products over distances of several meters has been investigated experimentally. Negative results were obtained with gaseous carriers. Transport efficiencies of 50 to 100% were obtained with carrier vapors. The vapor appears to form droplets in the system. The recoils are adsorbed physically by the droplets and carried with them through a capillary. There appears to be an active mechanism that forces the heavy constituents to the centre of the capillary cross section. The heavy constituents emerge from the capillary as a very narrow beam. Collection o…

Correction: Oncogenic extracellular HSP70 disrupts the gap-junctional coupling between capillary cells

2021

High levels of circulating heat shock protein 70 (HSP70) are detected in many cancers. In order to explore the effects of extracellular HSP70 on human microvascular endothelial cells (HMEC), we initially used gap-FRAP technique. Extracellular human HSP70 (rhHSP70), but not rhHSP27, blocks the gap-junction intercellular communication (GJIC) between HMEC, disrupts the structural integrity of HMEC junction plaques, and decreases connexin43 (Cx43) expression, which correlates with the phosphorylation of Cx43 serine residues. Further exploration of these effects identified a rapid transactivation of the Epidermal Growth Factor Receptor in a Toll-Like Receptor 4-dependent manner, preceding its in…

"Melko onnellinen puhallinorkesteri" : tapaustutkimus Jyväskylän yliopiston puhallinorkesterista

2010

Tutkielman tavoitteena oli selvittää puhallinorkesterissa soittamisen merkitystä soittajalle sosiaalisena tapahtumana, sekä orkesteriharrastuksen eroja kuoroharrastukseen yhdessä olemisen muotona. Kuoroharrastuksen on todettu olevan erittäin merkittävä asia elämässä sitä harrastavalle, ja tämän tutkielman tarkoitus on tarkastella orkesteriharrastusta samasta näkökulmasta. Tutkielma toteutettiin tapaustutkimuksena, ja sen aineisto kerättiin verkossa täytettävän kyselyn avulla Jyväskylän yliopiston puhallinorkesteri Puhkupillien soittajilta syksyn 2009 aikana. Kysely toteutettiin pääpiirtein samanlaisena myös Musica-kuorolle, ja näin saatiin vertailukelpoisia tuloksia kuorosta sekä orkesteris…
