17O NMR and molecular mechanical studies of arylmethylenemalonaldehydes

1990

The 17O NMR spectra of six different arylmethylenemalonaldehydes were measured for various solvents and temperatures. The 17O NMR chemical shifts and line widths of the carbonyl oxygens of the malonaldehyde fragment show a clear variation in the series of monoaryl compounds studied. The differences between the 17O NMR chemical shifts of the formyl oxygens correlate well with two conformationally dependent 1H–1H and 1H–13C coupling constants for the same compounds. Molecular mechanical calculations were also performed in order to relate the present data with the conformational preferences of the malonaldehyde fragment of the arylmethylenemalonaldehydes.

(Un)sustainable creativity? Different manager-employee perspectives in the finnish technology sector

2020

The importance of creativity for working life and in organizations has increased in recent years. At the same time, the theme of sustainability has been intensely debated in research, society, and organizations. Together, creativity and sustainability have sometimes been described as a contradictory phenomenon: they are described in ways that place them in opposition to each other. To better understand creativity and sustainability and their differences from the perspective of people in different positions, we take advantage of a sociocultural approach in which we do not focus only on creative individuals but also on the impact of creativity on both organizational stakeholders and society a…

Mutual intelligibility among the sign languages of Belgium and the Netherlands

2015

AbstractIn an exploratory study of mutual intelligibility between the sign languages of the northern part of Belgium (Flemish Sign Language, VGT), the southern part of Belgium (French Belgian Sign Language, LSFB), and the Netherlands (Sign Language of the Netherlands, NGT), we tested the comprehension of VGT by signers of LSFB and NGT. In order to measure the influence of iconic structures (classifier constructions and constructed action) that linguistic analyses have shown to be similar across different sign languages, two genres were compared: narrative and informative signing. To investigate the effect of the overlap between the spoken languages surrounding the Dutch and Flemish Deaf com…

Kinetic control in the chiral recognition of three-bladed propellers

2010

The ion pair of the stereolabile C(3)-symmetric, i(+)o proton complex [1H](+) of diaza-macropentacycle 1 and the configurationally stable Delta-TRISPHAT ([Delta-3](-)) anion exists in the form of two diastereomers, namely, [Delta-(1.H)][Delta-3] and [Lambda-(1.H)][Delta-3], the ratio of which, in terms of diastereomeric excess (de) decreases in the order [D(8)]THF (28%)CD(2)Cl(2) (22%)CDCl(3) (20%)[D(8)]toluene (16%)C(6)D(6) (7%)[D(6)]acetone (0%) at thermodynamic equilibrium. Except in the case of [D(6)]acetone, the latter is reached after a period of time that increases from 1 h ([D(8)]THF) to 24 h (CDCl(3)). Moreover, the initial value of the de of [1.H][Delta-3] in CDCl(3), before the t…

Mesures, développement : le statut de la créativité en question

2016

Les particularités inhérentes à la créativité en tant que compétence transversale, analysées à partir d’une revue de littérature en psychologie et sociologie sur la mesure, le développement et les effets de la créativité, semblent lui conférer un statut restreint au sein du système éducatif français. D’une part, les incertitudes autour des effets à long terme de la créativité, tout comme la logique adéquationniste structurant l’organisation scolaire, maintiennent cette compétence à l’écart des principales finalités assignées au système éducatif français. D’autre part, celui-ci n’est pas outillé pour la mesurer, étant donné que ses méthodes d’évaluation ne permettent pas d’appréhender cette …

Infertility-related stress, anxiety and ovarian stimulation: can couples be reassured about the effects of psychological factors on biological respon…

2016

Abstract The aim of this prospective, longitudinal study was to examine the association between couples' pre-treatment psychological characteristics (state anxiety and infertility-related stress levels of both partners) and ovarian response during assisted reproductive technology treatment in a well-controlled sample. A total of 217 heterosexual couples (434 patients), suffering from primary infertility and undergoing their first assisted reproductive technology treatment at the Reproductive Medicine Unit of ANDROS Day Surgery Clinic in Palermo (Italy), were recruited. Psychological variables were assessed using the State Scale of State-Trait Anxiety Inventory (STAI-S) and the Fertility Pro…

Crisis, convivencia multicultural y "efectos de barrio". El caso de dos barrios de Valencia

2015

La inserción urbana de los inmigrantes se desestabiliza y se pone a prueba con la crisis y las políticas aplicadas. Si bien en Valencia se mantiene una convivencia tranquila, la situación de los servicios públicos aumenta la competencia por recursos escasos entre vecinos de diferentes orígenes. Este texto presenta, en el marco de la ciudad de Valencia, un análisis comparativo de dos barrios receptores de inmigrantes que presentan fuertes contrastes. Por un lado, Russafa un barrio céntrico popular y en proceso de gentrification; por otro, Els Orriols, un barrio periférico obrero. Aún con muchos rasgos comunes, la intensidad del recelo hacia el inmigrante varía de un barrio a otro en función …

Media-induced recovery: The effects of positive versus negative media stimuli on recovery experience, cognitive performance, and energetic arousal.

2017

Recent research has demonstrated that the use of hedonically positive interactive media content contributes to the satisfaction of recovery needs and is associated with recovery outcomes such as higher levels of cognitive performance and increased energetic arousal. The recovery effects of noninteractive media stimuli as well as of media content with negative affective valence, however, are less clear. The present investigation addressed this limitation of prior research on

Antitumoral activity of curcumin: an adjuvant therapeutic strategy

2021

Curcumin, an active substance contained in an Indian spice called turmeric or curcuma, is well known for its anti-inflammatory and antioxidant properties. In recent times, it was taken into account and studied as an antitumoral molecule, by relying on its interference on several biological mechanisms, such as the inhibition of inflammatory mediators, the enhancement of detoxifying enzymes’ action and processes of cell growth and proliferation. Studies show how the high dosage of curcumin in vitro inhibits colorectal tumor cells, pancreatic tumor cells, lung cancer cells and glioblastoma’s cells, interfering in signaling pathways as Wnt/β-catenin, NF-kB and PI3K/Akt and leading to cell cycle…
