Synchrotron x-ray transmission measurements and modeling of filters investigated for Athena
2020
International audience; Advanced Telescope for High-Energy Astrophysics is a large-class astrophysics space mission selected by the European Space Agency to study the theme "Hot and Energetic Universe." The mission essentially consists of a large effective area x-ray telescope and two detectors: the X-ray Integral Field Unit (X-IFU) and the Wide Field Imager (WFI). Both instruments require filters to shield from out-of-band radiation while providing high transparency to x-rays. The mission is presently in phase B; thus, to consolidate the preliminary design, investigated filter materials need to be properly characterized by experimental test campaigns. We report results from high-resolution…
O potrzebie wprowadzenia konstrukcji na wzór actio pro socio dla roszczeń deliktowych przeciwko syndykowi
2021
The study points to the urgent need to introduce legislative changes in the bankruptcy law, making it easier for aggrieved creditors to pursue ex delicto compensation claims against a person who has committed a tort while acting as a trustee in bankruptcy during the bankruptcy proceedings. The possibility for an individual creditor to pursue all claims against the trustee in bankruptcy for the benefit of the entire community of creditors would improve the compensation function of Article 415 of the Civil Code and Article 160(3) of the Insolvency Law, the preventive function, and the repressive function. Such a mechanism evokes obvious associations with actio pro socio. The study presents th…
Towards Controlled Synthesis of Water-Soluble Gold Nanoclusters : Synthesis and Analysis
2019
Water-soluble gold nanoclusters with well-defined molecular structures and stability possess particular biophysical properties making them excellent candidates for biological applications as well as for fundamental spectroscopic studies. The currently existing synthetic protocols for atomically monodisperse thiolate-protected gold nanoclusters (AuMPCs) have been widely expanded with organothiolates, yet the direct synthesis reports for water-soluble AuMPCs are still deficient. Here, we demonstrate a wet-chemistry pH-controlled synthesis of two large water-soluble nanoclusters utilizing p-mercaptobenzoic acid (pMBA), affording different sizes of plasmonic AuMPCs on the preparative scale (∼7 …
An Easy Route Towards Regioselectively Difunctionalized Cyclens and New Cryptands.
2006
Reductive amination of various aldehydes with cyclen represents a very convenient method for the synthesis of a wide range of 1,7-difunctionalized cyclens, as well as new cryptands.
Creativity by copying: imitating life as a work of imagination
2021
Engineering biological systems is easily interpretable as a process of mere and cold replication, or even distortion, of the natural domain, since it is often linked to industry and built on the Cartesian assumption of human rationality’s control over asubmissive nature. In this article, I approach living systems design from an alternative perspective, supporting its similarities with activities which are traditionally associated with creativity, like arts. I show that different kinds of creativity are deeply involved in copying, composing, and modifying life, focusing on two different levels: that of scientific modelling, recognisable by looking at biological circuits design, and that of a…

The nonstationary Maxwell system in domains with edges and conical points
2005
Sergey Matyukevich on väitöskirjassaan tutkinut Maxwell-yhtälöä alueilla, joilla on kartiomaisia kärkiä ja teräviä särmiä. Erityisen huomion kohteena tutkimuksessa oli tutkia yhtälön ratkaisujen käyttäytymistä lähellä ns. singulaaripisteitä, joita epäsileät reunat aiheuttavat. Tutkimuksessa Matyukevich on johtanut ratkaisuille eksplisiittisiä, asymptoottisia laajennuksia alueen kartiomaisten kärkien ja terävien särmien ympäristössä.Tutkimuksen tuloksilla on merkitystä siinä, että niitä voidaan soveltaa useiden ei-stationaaristen sähkömagnetiikan yhtälöiden matemaattisessa ja numeerisessa analysoinnissa epäsileillä alueilla. We study the nonstationary Maxwell system in domains with conical p…

Lukion sähköopin ja sähkömagnetismin opetusmateriaalien tietorakenteiden kartoittaminen ja kehitysehdotusten etsiminen
2011
Sähköopin ja sähkömagnetismin aihekokonaisuudet ovat lukion kurssien tuntimääriin nähden raskaita ja tietoa on hyvin paljon. Työn tavoitteena oli selvittää voisiko lukion sähköopin ja sähkömagnetismin tietorakenteita ja samalla koko aihekokonaisuuksia keventää. Työssä tarkastellaan käsitekarttoja käyttäen huomattavan laajoja aihekokonaisuuksia, tarkoituksena luoda pohjaa opintokokonaisuuksien edelleenkehittämiselle. Kokonaisuutena työ tarjoaa yksittäiselle opettajalle ideoita oman opetuksensa päivittämiseen ja laajemmin mahdollisuuksia oppimateriaalien kehittämiselle. Työn laaja tarkastelupohja lisää tulosten soveltamismahdollisuuksia. Tietorakenteita pyrittiin kartoittamaan koottujen käsit…
