Paradoksi un maldīgi spriedumi statistikā
2021
Šajā darbā tiek aprakstīti vairāki paradoksi un maldīgie spriedumi statistikā, kurus ir būtiski izprast, lai izdarītu korektus secinājumus par datiem dažādās zinātnēs, piemēram, epidemoloģijā, tiesību zinātnē, sociālajās zinātnēs. Kaut arī liela daļa no šiem fenomeniem tika aplūkoti jau 20. gadsimtā, ar paradoksiem saistītie rezultāti vēl joprojām var būt intuitīvi nesaprotami, kaut arī no statistikas viedokļa tie ir korekti. Savukārt, maldīgie spriedumi, kuri var likties loģiski, bet noved pie nepareiza rezultāta, joprojām ir sastopami rakstos. Darbā fenomeni tiek aprakstīti un doti piemēri.
Syntheses of Trifluoroethylated N-Heterocycles from Vinyl Azides and Togni’s Reagent Involving 1,n-Hydrogen-Atom Transfer Reactions
2020
2,2,2-Trifluoroethyl-substituted 3-oxazolines, 3-thiazolines, and 5,6-dihydro-2H-1,3-oxazines have been obtained by reacting substituted vinyl azides with a combination of Togni’s reagent and substoichiometric amounts of iron(II) chloride. The results of density functional theory calculations support the proposed mechanism involving 1,n-hydrogen-atom transfer reactions. peerReviewed
On Psychological Aspects about Electric Vehicles, Part 1
2021
The high diffusion of electric vehicles is evidenced by every sector magazine or by the catalog of all the manufacturers inserting incessantly new models. But what are the user's most hidden reactions to the new world of vehicles? Is the user ready for the fifth level of automation (fully automatic driving and absence of the driving position)? The purpose of this paper is to present and discuss the psychological aspects that influence the adoption of electric vehicles by users and beyond. Topics such as the egg and chicken paradox (electric vehicles and charging stations, who was born first) but also performance anxiety (range anxiety) will be addressed. Contradictions and irony will charac…
A Tunable, Fullerene‐Based Molecular Amplifier for Vibrational Circular Dichroism
2019
Abstract Vibrational circular dichroism (VCD) studies are reported on a chiral compound in which a fullerene C60 moiety is used as an electron acceptor and local VCD amplifier for an alanine‐based peptide chain. Four redox states are investigated in this study, of which three are reduced species that possess low‐lying electronic states as confirmed by UV/Vis spectroelectrochemistry. VCD measurements in combination with (TD)DFT calculations are used to investigate (i) how the low‐lying electronic states of the reduced species modulate the amplification of VCD signals, (ii) how this amplification depends on the distance between oscillator and amplifier, and (iii) how the spatial extent of the…
Giustificazione epistemica e responsabilità cognitiva nel Teeteto
2011
Sullo sfondo di un'interpretazione della critica al relativismo e allo scetticismo sofistico nel Teeteto che individua come suo esito la delineazione di un'epistemologia del dialeghesthai elenchico incentrata su una concezione fallibilista della verità come homologhia, il saggio cerca di mostrare come in questo dialogo platonico emerga il modello di un rapporto mente-mondo mediato concettualmente e razionalmente, diverso sia dal modello sofistico di conoscenza come passiva aisthesis, sia da quello di una pura conoscenza non contaminata dalla percezione che Platone sembrava voler sostenere con la Teoria dei due mondi. Una tale ipotesi di lettura è centrata sull'identificazione del nucleo più…

The orthodox liturgical year and its theological structure
2022
The concept of ‘liturgical year’ indicates a reference to the meaning of the measuring units of civil time, and especially to the cosmic entities that determine the general rhythm of time – the sun and the moon. Interestingly, the liturgical time depends both on the structure of civil time, and, on the two discrete systems of the solar and lunar cycles, which have always been underpinnings of time measuring. The special importance and influence that the cosmical rhythms exert on the entire human life are also felt in the structure and theology of the liturgical time, where it signals the attempt to merge and reconcile the cosmical solar and lunar cycles within the liturgical year. This lead…
Physical chemical properties and kinetics of redox processes in water/soybean oil microemulsions
2008
Microemulsoes de agua em oleo (ME w/o) constituidas de agua, oleo de soja, SDS (dodecil sulfato de sodio) e diversos alcoois de cadeia curta foram caracterizadas sob o ponto de vista fisico-quimico e de propriedades eletroanaliticas. Foram testados diferentes co-surfactantes e razoes surfactante:cosurfactante, sendo a ME com a composicao mais favoravel utilizada para estudar a cinetica de processos redox. Para tanto, realizaram-se medidas de voltametria ciclica utilizando como eletrodo de trabalho um ultramicroeletrodo de disco de Pt e, como eletrodo de referencia e auxiliar, foram usados Ag/AgCl e Pt, respectivamente, e ferroceno como uma sonda. Verificou-se que a estabilidade termodinâmic…
Involvement of an Alkane Hydroxylase System of Gordonia sp. Strain SoCg in Degradation of Solid n-Alkanes▿
2010
ABSTRACT Enzymes involved in oxidation of long-chain n -alkanes are still not well known, especially those in Gram-positive bacteria. This work describes the alkane degradation system of the n -alkane degrader actinobacterium Gordonia sp. strain SoCg, which is able to grow on n -alkanes from dodecane (C 12 ) to hexatriacontane (C 36 ) as the sole C source. SoCg harbors in its chromosome a single alk locus carrying six open reading frames (ORFs), which shows 78 to 79% identity with the alkane hydroxylase (AH)-encoding systems of other alkane-degrading actinobacteria. Quantitative reverse transcription-PCR showed that the genes encoding AlkB (alkane 1-monooxygenase), RubA3 (rubredoxin), RubA4…
