A second solvatomorph of poly[[μ4-N,N′-(1,3,5-oxadiazinane-3,5-diyl)bis(carbamoylmethanoato)]nickel(II)dipotassium] : crystal structure, Hirshfeld su…
2021
The title compound, poly[triaquabis[μ4-N,N′-(1,3,5-oxadiazinane-3,5-diyl)bis(carbamoylmethanoato)]dinickel(II)tetrapotassium], [K4Ni2(C7H6N4O7)2(H2O)3] n , is a second solvatomorph of poly[(μ4-N,N′-(1,3,5-oxadiazinane-3,5-diyl)bis(carbamoylmethanoato)nickel(II)dipotassium] reported previously [Plutenko et al. (2021). Acta Cryst. E77, 298–304]. The asymmetric unit of the title compound includes two structurally independent complex anions [Ni(C7H6N4O7)]2−, which exhibit an L-shaped geometry and consist of two almost flat fragments perpendicular to one another: the 1,3,5-oxadiazinane fragment and the fragment including other atoms of the anion. The central Ni atom is in a square-planar N2O2 co…
Species–area relationships in continuous vegetation: Evidence from Palaearctic grasslands
2019
Aim Species-area relationships (SARs) are fundamental scaling laws in ecology although their shape is still disputed. At larger areas, power laws best represent SARs. Yet, it remains unclear whether SARs follow other shapes at finer spatial grains in continuous vegetation. We asked which function describes SARs best at small grains and explored how sampling methodology or the environment influence SAR shape. Location Palaearctic grasslands and other non-forested habitats. Taxa Vascular plants, bryophytes and lichens. Methods We used the GrassPlot database, containing standardized vegetation-plot data from vascular plants, bryophytes and lichens spanning a wide range of grassland types throu…

The castle's Hermitage of Yecla (Region of Murcia) constituted during the 13th to 16th centuries the first parish of the population, hosting a triptych-shaped altarpiece presided over by a tempera painting on wood of Our Lady of Humility or "Virgo Lactans", dated around 1370 and attributed to the painter Barnaba da Modena, which was the titular image of the mentioned temple under the title of Our Lady of the Incarnation, until at the end of the 18th century it changed ownership for the Conception of Our Lady. The table at averages of the eight hundred was placed in an a loft, appropriating it at the beginning of the 20th century by the retired military Pascual Spuche y Lacy, who sold it aro…
Pelon ja vihan voimalla : Rajat kiinni! -kansanliikkeen suomalaisuuden suojeluun verhottu rasistinen diskurssi vuosina 2015-2017
2017
Tutkimuksen tehtävänä on selvittää, kuinka toistuva vihapuhe vaikuttaa ihmisten asenteisiin ja maailmankuvaan. Tutkimuksen taustalla on kiinnostukseni laajempaan ilmiöön yhteiskunnallisen diskurssin muutoksesta rasistisia näkemyksiä hyväksyväksi. Tutkin vuoden 2015 pakolaiskriisiin vastauksena syntynyttä Rajat kiinni! -kansanliikettä esimerkkinä globalisaation ajan muukalaisvihamielisestä liikehdinnästä, joka toiminnallaan ja puhetavoillaan ylläpitää pelon ja vihan ilmapiiriä. Tutkimuksen analyysimenetelmänä on käytetty diskurssianalyysia ja sosiaalisten liikkeiden analyysia. Kielenkäytön kautta muodostetun todellisuuden ja sitä vastaavan kollektiivisen toiminnan ja identiteetin tutkimisen …
Soziale Medien als fünfte Gewalt: Strategische Organisation deutscher und finnischer Gegenredekampagnen auf Facebook
2023
Social media, as the fifth estate, increasingly influence public discourses and play a major role in shaping public opinion. Undoubtedly, they have the potential to promote participation and democracy. On the other side, they also constitute a risk for democratic societies, as the spread of hate speech and fake news has shown. As a response, forms of counterspeech organised by civil society have emerged in social media to counter the normalisation of hate speech and democracy-threatening discourses. In order to influence discourse in social media in terms of the fifth estate, counterspeech campaigns must be visible also quantitatively. In this ethnographic contrastive study, I analysed…
Ihmisoikeudet, demokratia ja sosiaalinen oikeudenmukaisuus opettajankoulutuksessa
2020
Tarkastelemme tässä artikkelissa demokratia- ja ihmisoikeuskasvatuksen toteutumista opettajankoulutuksessa Suomessa ja viitteitä yhteiskunnallisen ilmapiirin muutoksesta ihmisoikeuksien ja demokratian kannalta negatiiviseen suuntaan. Tuomme esiin näkökulmia yhteiskunnallisiin osallistumismahdollisuuksiin kielellisten oikeuksien ja erilaisten taustatekijöiden suhteen. Demokratia- ja ihmisoikeuskasvatuksen ydinsisältöihin kuuluu edistää sosiaalista oikeudenmukaisuutta sekä inklusiivista ja moniäänistä kasvatusta sekä teoreettisesti että käytännöllisesti. Tutkimuksemme mukaan demokratia- ja ihmisoikeuskasvatus ei tällä hetkellä toteudu opettajankoulutuksessa eksplisiittisesti, vaikka opettajak…
The effect of peracetic acid on microbial community, water quality, nitrification and rainbow trout (Oncorhynchus mykiss) performance in recirculatin…
2020
Microbial biofilters control water quality and enable the overall function of recirculation aquaculture systems (RAS). Changes in environmental conditions can affect the abundance and interactions of the diverse microbial populations of the biofilter, affecting nitrification of harmful ammonium and thus fish health. Here, we examined the effect of different application frequencies (0, 1, 2 and 4 times per week) of a common disinfectant, peracetic acid (PAA, applied 1.1 mg l−1 twice per day), on biofilter microbial communities, focusing especially on nitrifying microbial groups and using a high throughput sequencing of 16S rRNA gene and quantitative PCR (qPCR). In addition, we measured biofi…
Bond Stretching and Redox Behavior in Coinage Metal Complexes of the Dichalcogenide Dianions [(SPh2P)2CEEC(PPh2S)2]2− (E=S, Se): Diradical Character …
2011
The metathetical reactions of a) [Li(tmeda)]2[(S)C(PPh2S)2] (Li2⋅3 c) with CuCl2 and b) [Li(tmeda)]2[(SPh2P)2CSSC(PPh2S)2] (Li2⋅4 c) with two equivalents of CuCl both afford the binuclear CuI complex {Cu2[(SPh2P)2CSSC(PPh2S)2]} (5 c). The elongated (C)S[BOND]S(C) bond (ca. 2.54 and 2.72 Å) of the dianionic ligand observed in the solid-state structure of 5 c indicate the presence of diradical character as supported by theoretical analyses. The treatment of [Li(tmeda)]2[(SPh2P)2CSeSeC(PPh2S)2] (Li2⋅4 b) and Li2⋅4 c with AgOSO2CF3 produce the analogous AgI derivatives, {Ag2[(SPh2P)2CEEC(PPh2S)2]} (6 b, E=Se; 6 c, E=S), respectively. The diselenide complex 6 b exhibits notably weaker Ag[BOND]Se…
Dioxomolybdenum(VI) complexes of hydrazone phenolate ligands -syntheses and activities in catalytic oxidation reactions
2021
The new cis-dioxomolybdenum(VI) complexes [MoO2(L2)(H2O)] (2) and [MoO2(L3) (H2O)] (3) containing the tridentate hydrazone-based ligands (H2L2 = N'-(3,5-di-tert-butyl-2-hydroxybenzylidene)-4-methylbenzohydrazide and H2L3 = N'-(2-hydroxybenzylidene)-2-(hydroxyimino)propanehydrazide) have been synthesised and characterized via IR, 1H and 13C NMR spectroscopy, mass spectrometry, and single crystal X-ray diffraction analysis. The catalytic activities of complexes 2 and 3, and the analogous known complex [MoO2(L1)(H2O)] (1) (H2L1 = N'-(2-hydroxybenzylidene)-4-methylbenzohydrazide) have been evaluated for various oxidation reactions, viz. oxygen atom transfer from dimethyl sulfoxide to triphenylp…
Beta-spectrum shapes of forbidden β decays
2018
The neutrinoless [Formula: see text] decay of atomic nuclei continues to attract fervent interest due to its potential to confirm the possible Majorana nature of the neutrino, and thus the nonconservation of the lepton number. At the same time, the direct dark matter experiments are looking for weakly interacting massive particles (WIMPs) through their scattering on nuclei. The neutrino-oscillation experiments on reactor antineutrinos base their analyses on speculations of [Formula: see text]-spectrum shapes of nuclear decays, thus leading to the notorious “reactor antineutrino anomaly.” In all these experimental efforts, one encounters the problem of [Formula: see text]-spectrum shapes of…
