The Nature of Transannular Interactions in E4N4 and E82+ (E = S, Se)
2012
The electronic structures of tetrachalcogen tetranitrides, E4N4, and octachalcogen dications, E82+, and the nature of their intramolecular E···E interactions (E = S, Se) was studied with high-level theoretical methods. The results reveal that the singlet ground states of both systems have a surprisingly large correlation contribution which functions to weaken and therefore lengthen the cross-ring E–E bond. The observed correlation effects are primarily static in E4N4, whereas in E82+ the dynamic part largely governs the total correlation contribution. The presented description of bonding is the first that gives an all-inclusive picture of the origin of cross-ring interactions in E4N4 and E8…
Structures and EPR spectra of binary sulfur−nitrogen radicals from DFT calculations
2007
he scattered electron paramagnetic resonance (EPR) spectroscopic data for binary sulfur–nitrogen (S,N) radicals have been compiled and critically assessed.Many of these are inorganic rings or cages.For each species, possible equilibrium structures in the gas phase and the EPR hyperfine coupling (hfc) constants have been calculated with DFT using the B3LYP functional and basis sets of triple-ζ (or better) quality.Good agreement is obtained between calculated and measured values for the well characterized [S3N2]+radical dot, a planar π-radical for which the s-component of the orbitals is likely to be reasonably independent of minor geometrical changes between gas-phase and condensed-phase sta…
Electrochemical and Electronic Structure Investigations of the [S3N3]• Radical and Kinetic Modeling of the [S4N4]n/[S3N3]n (n = 0, −1) Interconversion
2009
Voltammetric studies of S4N4 employing both cyclic (CV) and rotating disk (RDE) methods in CH2Cl2 at a glassy carbon electrode reveal a one-electron reduction at −1.00 V (versus ferrocene/ferrocenium), which produces a second redox couple at −0.33 V, confirmed to be the electrochemically generated [S3N3]− by CV studies on its salts. Diffusion coefficients (CH2Cl2/0.4 M [nBu4N][PF6]) estimated by RDE methods: S4N4, 1.17 × 10−5 cm2 s−1; [S3N3]−, 4.00 × 10−6 cm2 s−1. Digital simulations of the CVs detected slow rates of electron transfer for both couples and allowed for a determination of rate constants for homogeneous chemical reaction steps subsequent to electron transfer. The common paramet…
The Effect of Mechanocatalytic Pretreatment on the Structure and Depolymerization of Willow
2020
In this study, the effect of a mechanocatalytic pretreatment on the structure of willow and sugar release from pretreated willow was explored. In the mechanocatalytic approach, the pretreatment consists of solvent-free impregnation with sulfuric acid and a mechanical treatment with ball milling. Willow sawdust and pretreated samples were analyzed with field emission scanning electron microscope and X-ray diffraction. The products in the sugar solution were determined as the total reducing sugars with the 3,5-dinitrosalicylic acid method and monosaccharides with capillary electrophoresis. According to the results, milling increased the sugar production, depending on the sulfuric acid load. T…
Rilkean Memories and the Self of a Robot
2019
This paper discusses the concept of Rilkean memories, recently introduced by Mark Rowlands, to analyze the complex intermix of hardware and software related to the self of a robot. The Rilkean memory of an event is related to the trace of that episode left in the body of the individual. It transforms the act of remembering into behavioral and bodily dispositions, thus generating the peculiar behavioral style of the individual, which is at the basis of her autobiographical self. In the case of long-life operating robots, a similar process occurs: the software of the robot has to cope with the changes that happened in the body of the robot because of damaging events in its operational life. T…
CAMBIO DE ACTITUDES Y VALORES ANTE LA ENERGÍA TRAS EL USO DE UN JUEGO DE ROL
2010
Los juegos de rol en educación se han definido como dramatizaciones que se vertebran en torno a una situación concreta y utilizan la asignación de papeles a alumnos, quienes deberán defender con argumentos una opinión (previamente perfilada) frente a un problema. Cada vez más utilizados en la educación formal y no formal, destacan entre sus ventajas el convertir lo lúdico en aprendizaje, potenciar el aprendizaje de actitudes y valores y la conexión que se realiza con la vida real entre otros. La utilización de un juego de rol en una investigación educativa sobre cambio de actitudes y valores ante los recursos energéticos cuyos resultados educativos fueron positivos, permitió repetir dicha i…
Newborn crawling and rooting in response to maternal breast odor
2021
International audience; A growing literature shows that perception and action are already tightly coupled in the newborn. The current study aimed to examine the nature of the coupling between olfactory stimuli from the mother and the newborn's crawling and rooting (exploratory movements of the head). To examine the coupling, the crawling and rooting behavior of 28 2-day-old newborns were studied while they were supported prone on a mobility device shaped like a mini skateboard, the Crawliskate®, their head positioned directly on top of a pad infused with either their mother's breast odor (Maternal) or the odor of water (Control). Video and 3D kinematic analyses of the number and types of li…

Two decades of discussion on charitable food aid in Finland : analysing the framing by and through the media
2016
Jo kaksi vuosikymmentä virallisen sosiaalipolitiikan rajapinnoilla toiminut ruoka-apu on murrosvaiheessa: Tulisiko toiminta hiljaisen hyväksynnän sijaan tunnustaa, jolloin avun kohdentamista ja järjestämistä voidaan avoimesti kehittää yhdessä kirkon, kunnallisen sosiaalitoimen ja yksityisen sektorin kesken? Onko toiminnan fokus siirtymässä väliaikaiseksi tarkoitetusta akuutin nälän torjunnasta kohti sosiaalipoliittisen ruoka- köyhyyden ja ekologisen ruokahävikin ongelmat yhdistävää ratkaisumallia? Julkisen, yksityisen ja kolmannen sektorin yhteistyönä toteutettavan saksalaisen ruoka-apumallin (Berliner Tafel -ruokapankkiverkosto) rantautuminen Suomeen (Yhteinen Pöytä …
