Impugnazione erroneamente proposta e limiti alla "conversione"
2022
Conversion, here considered sub specie of the correct qualification of the appeal, is going through a period of uncertain case law. Beside some standpoints – its inapplicability to heterogeneous appeals – there still remain deep uncertainties, which can undermine the principle of favor impugnationis, with an inevitable negative impact on the effectiveness of the system of criminal remedies.
The room temperature crystal structure of a bacterial phytochrome determined by serial femtosecond crystallography
2016
Scientific reports 6, 35279 (2016). doi:10.1038/srep35279
Revisiting the bromination of 3β-hydroxycholest-5-ene with CBr4/PPh3 and the subsequent azidolysis of the resulting bromide, disparity in stereochemi…
2023
Cholesterol reacts under Appel conditions (CBr4/PPh3) to give 3,5-cholestadiene (elimination) and 3β-bromocholest-5-ene (substitution with retention of configuration). Thus, the bromination of cholesterol deviates from the stereochemistry of the standard Appel mechanism due to participation of the Δ5 π-electrons. In contrast, the subsequent azidolysis (NaN3/DMF) of 3β-bromocholest-5-ene proceeds predominantly by Walden inversion (SN2) affording 3α-azidocholest-5-ene. The structures of all relevant products were revealed by X-ray single crystal structure analyses, and the NMR data are in agreement to the reported ones. In light of these findings, we herein correct the previous stereochemical…
Crystal structure and absolute configuration of (4S,5R,6S)-4,5,6-trihydroxy-3-methylcyclohex-2-enone (gabosine H)
2017
The absolute configuration of the title compound, determined as 4S,5R,6S on the basis of the synthetic pathway, was confirmed by single-crystal X-ray diffraction. The molecule is formed by a substituted six-membered cyclohexene ring adopting an envelope conformation and substituted by carbonyl, methyl and hydroxyl groups. The supramolecular structure is mainly built by a combination of O—H⋯O and weaker C—H⋯O hydrogen bonds.
5,10-Dihydroindeno[2,1-a]indene
2019
The title compound, C16H12, crystallizes with four half molecules in the asymmetric unit, each of which is located on a crystallographic centre of inversion. The molecules are essentially planar. The crystal studied was a non-merohedral twin.

Cybersex in the “Net generation”: Online sexual activities among Spanish adolescents
2016
The internet offers several opportunities to explore sexuality among adolescents. However, some studies have also revealed problematic effects of cybersex in earlier stages. Despite this, few studies analyze the online sexual behavior among adolescents, even less in Spain where there is very little data. For this reason, our aim is to examine the use of internet for sexual purposes among Spanish adolescents, including gender differences. Three hundred and twenty-two adolescents completed an ad-hoc questionnaire and the Spanish version of the Internet Sex Screening Test. In general, boys report more cybersex than girls do, for example, in masturbating while the Internet (60.6% of boys and 7.…
Analyse didactique clinique des savoirs enseignés par un entraineur en basket-ball
2015
Cette recherche s’inscrit dans le cadre scientifique de la didactique clinique de l’Education Physique et Sportive (EPS). Sa caractéristique repose sur la prise en compte du sujet enseignant, de son histoire et de ses effets sur sa pratique d’enseignement. Cet article analyse la transmission du savoir par un entraîneur de basket-ball au regard de son expérience dans l’activité. L’étude de cas d’un professionnel de métier, permet de rendre compte d’une double nature de savoirs enseignés : des savoirs techniques, prioritaires et diversifiés, et des savoirs tactiques, globalement rattachés à la gestion du jeu. Elle met également en perspective l’existence d’un décalage entre les savoirs enseig…
Los beneficios del mar: negocios e inversiones económicas de la oficialidad naval en el siglo XVIII
2019
Throughout the eighteenth century, the Spanish navy was extensively reformed and enhanced as a consequence of the new model of Monarchy that the Bourbons introduced. Among the measures adopted, it is remarkable the erection of the naval officers corps according to the needs and obligations that maritime war had in this century. This group becomes the paradigm of the new professionalization and new training approach, and its members had great relevance due to its great mobility around the empire and the power of the naval institution. This means that a part of the naval officers were placed in privileged positions and at the intersection of diverse political, social and economic networks. Th…

The COVID-19 pandemic and social distancing measures targeting the transmission of the virus impacted everyday life in 2020. This study investigated pre- to in-pandemic changes in health behaviors and depressive symptoms during the COVID-19 pandemic and the role of personality traits in these changes in Finland. Data from a larger population-based cohort study of 51–59-year-old Finnish women were used (n = 358). Self-reported questionnaires gathered information about depressive symptoms, eating behavior, physical activity, and alcohol consumption before the pandemic time, at the onset, and at the end of the COVID-19 emergency conditions. Information about personality traits (extraversion an…
