Influencing the self‐sorting behavior of [2.2]paracyclophane based ligands by introducing isostructural binding motifs
2020
Two isostructural ligands with either nitrile ( L nit ) or isonitrile ( L iso ) moieties directly connected to a [2.2]paracyclophane backbone with pseudo‐meta substitution pattern have been synthesized. The ligand itself ( L nit ) or its precursors ( L iso ) were resolved via HPLC on a chiral stationary phase and the absolute configuration of the isolated enantiomers was assigned by XRD analysis and/or by comparison of quantum‐chemical simulated and experimental ECD‐spectra. Surprisingly, the resulting metallosupramolecular aggregates formed in solution upon coordination of [(dppp)Pd(OTf) 2 ] differ in their composition: whereas L nit forms dinuclear complexes L iso exclusively forms trinuc…
Dal disegno alla misura. Ricostruzione del fronte di palazzo Aiutamicristo a Palermo
2020
I laser scanner e la fotogrammetria SfM hanno scardinato il legame tradizionale fra misura e disegno, fissato negli eidotipi che spesso prefiguravano i disegni di restituzione. Il contributo che segue intende dimostrare, attraverso una esemplificazione su un caso studio, che le tecnologie digitali e il lavoro di indagine su repliche del reale, esaltano, attraverso nuovi modi di interazione fra disegno e misura, la possibilità di indagare l’architettura costruita per decodificarne lo schema, il progetto. Il caso studio prescelto è il fronte principale di palazzo Aiutamicristo, costruito a Palermo a partire dal 1490 su progetto di Matteo Carnilivari. Il prospetto di palazzo Aiutamicristo avrà…
Fluorinated heterocyclic compounds: an assay on the photochemistry of some fluorinated 1-oxa-2-azoles: an expedient route to fluorinated heterocycles
2004
Abstract Photoinduced heterocyclic rearrangements of ON bond-containing azoles have been claimed in the synthesis of target fluorinated heterocyclic compounds. In this context, the photochemical behavior of some fluorinated 1,2,4-oxadiazoles has been investigated. Irradiations of 3-amino-5-perfluoroalkyl-1,2,4-oxadiazoles at λ =313 nm in methanol gave open-chain products arising from a reaction of the nucleophilic solvent with either the first formed ring-photolytic species or with a nitrilimine moiety generated from it. Differently, irradiations in methanol with the presence of triethylamine (TEA) followed competing phototransposition pathways leading to the ring-isomers 2-amino-5-perfluo…
Bailiaspis (Trilobita) with English affinities from the Mansilla Formation (Cambrian Series 3 of the Iberian Chains; NE Spain)
2020
A new study of the trilobite record in the Mansilla Formation (Iberian Chains, NE Spain) has led to the discovery of the presence of Bailiaspis aff. tuberculata, B. cf. tuberculata and Bailiaspis sp., the first certain citation of this genus in the Mediterranean subprovince. The age of the findings extends from Eccaparadoxides asturianus Zone (upper Leonian) to the lowermost Badulesia tenera Zone (lower Caesaraugustan), which correspond to the upper part of Stage 5 of Cambrian Series 3 and, probably, the lowermost Drumian. The specimens show the cranidial anterior border expanding backwards, forming a plectrum that is characteristic of Bailiaspis. The main characters of the three taxa inclu…
Visualising maritime vessel open data for better situational awareness in ice conditions
2018
Situational awareness of maritime vessels in ice conditions is important for the operation of supply chains. In the artic sea areas, the ice conditions pose a major challenge for maritime vessels getting stuck in the ice and being significantly delayed in arrival to harbor. Data science and open data provide new opportunities to overcome these challenges. This paper introduces available open data sources and data visualizations that can be used to develop applications, for example, for detecting maritime vessel collision, predicting estimated time of arrival to harbor, as well as maritime vessel route optimization in ice conditions. The paper begins by introducing available open data source…
Harnessing Women’s Potential as a Soft Engine for Growth : Lessons from Contrasting Trajectories between Finland and Japan for Growing Economies
2017
Harnessing the vigor of women’s potential is essential for inclusive economic growth in a digital economy moving toward aging society. This can be a soft engine for sustainable growth substitutable for costly hard investment. While there exists explicit evidence of a virtual cycle between economic growth and gender balance improvement, emerging countries cannot afford to overcome the constraints of low income. Given the foregoing, this paper analyzed possible co-evolution between economic growth, gender balance improvement and digital innovation initiated by information and communication technology (ICT) advancement. Using a unique dataset representing the state of gender balance improvemen…
Haarautunut evakkotie : viipurilaisten organisaatioiden uudet kotipaikat
2021
The text examines the relocation of ceded Vyborg’s administrative, social and cultural institutions in the rest of Finland. The heritage of the city was fragmented over a large area because the remaining part of Karelia did not have a city large enough to accommodate the Vyborgian facilities. In this respect, the competition between the fairly strong regional centres slowed down the urban development of the whole of Eastern Finland. peerReviewed
Liikunnanopettajaksi opiskelevien käsityksiä liikunnan-opetuksesta seka- ja erillisryhmissä
2017
Parpala, Eetu & Siljanto, Lassi. ”Liikunnanopettajaksi opiskelevien käsityksiä liikunnanopetuksesta seka- ja erillisryhmissä”. 2017. Kasvatustieteiden pro gradu –tutkielma. Jyväskylän yliopisto. Opettajankoulutuslaitos. Tutkimuksen tarkoituksena oli selvittää liikunnanopettajaksi opiskelevien käsityksiä liikunnanopetuksesta sekaryhmissä ja erillisryhmissä. Tutkimus pyrkii tuomaan uusia näkökulmia liikunnanopetukseen, erityisesti opetusryhmien muodostamiseen, selvittämällä liikunnanopettajaksi opiskelevien mielipiteitä ja kokemuksia. Kokemusten ja käsitysten tutkiminen ja selvittäminen ovat avainasemassa, kun kyse on opettajan ja oppilaiden viihtymisestä koulun liikuntatunnilla. Myös ryhmäja…
Työtä, turvaa ja tasa-arvoa! : työpreferenssit ja työelämään sijoittuminen vastavalmistuneilla AMK-insinööreillä
2015
Tämän tutkimuksen tehtävänä on selvittää vuonna 2013 valmistuneiden AMK-insinöörien työuran alkuvaiheita. Tavoitteena on tuottaa tietoa työllistymisestä, työpreferensseistä ja preferenssien taustalla olevista tekijöistä. Tutkimus on kvantitatiivinen sekundäärianalyysi, joka pohjautuu Insinööriliiton toimesta kesällä 2014 tekemääni vastavalmistuneiden sijoittumistutkimukseen. Tutkimuksen perusjoukon muodostavat kyselyhetkellä Insinööriliittoon (IL) ja diftingenjörsförbundet i Finland:iin (DIFF) kuuluneet, vuonna 2013 valmistuneet insinöörit. Kyselylomake lähetettiin 1600 vuonna 2013 valmistuneelle insinöörille, joista viisi prosenttia oli DIFF: in jäseniä. Vastauksia tuli yhteensä 794 kappal…
