Vibronic Model for Intercommunication of Localized Spins via Itinerant Electron
2019
In this article, we propose a vibronic pseudo Jahn–Teller model for partially delocalized mixed-valence molecules aimed to describe the magnetic coupling between the localized spins mediated by the delocalized electron. The simplest partially delocalized system that retains the main studied features is assumed to consist of a one-electron mixed-valence dimer, which is connected to the two terminal magnetic ions. The model involves the following key interactions: electron transfer in the spin-delocalized subsystem of a mixed-valence molecule, which is mimicked by a dimeric unit, coupling of the itinerant electrons with the molecular vibrations, and isotropic magnetic exchange between the loc…
NIR-absorbing transition metal complexes with redox-active ligands
2020
Bench top stable transition metal (M = Co, Ni, Cu) complexes with a non-innocent ortho-aminophenol derivative were synthesized by the reaction of metal(II)acetates with a ligand precursor in 2:1 ratio. The solid-state structures reveal the formation of neutral molecular complexes with square planar coordination geometries. The Co(II) and Cu(II) complexes are paramagnetic, whereas the Ni complex is a diamagnetic square planar low-spin Ni(II) complex. All complexes, and Ni(II) complex in particular, show strong absorption in the near-IR region. Peer reviewed
User experiences of a mobile mental well-being intervention among pregnant women
2016
Postnatal depression affects 10 to 15 percent of women after childbirth. Acceptance and commitment therapy (ACT) is associated with better mental well-being and lower levels of depression. Digital ACT solutions enable providing potentially cost-effective access to interventions. This paper reports the user experiences of an ACT-based mobile mental well-being intervention among pregnant women. Twenty-nine mothers were recruited to a 6-month study. Usage rates were collected via usage logs and user experiences via questionnaires and interviews. The total usage time of the application was about 53 min per user. The application was perceived easy to use. The most common barriers of use were: co…
Enhancing Disaster Response for Hazardous Materials Using Emerging Technologies: The Role of AI and a Research Agenda
2019
Despite all efforts like the introduction of new training methods and personal protective equipment, the need to reduce the number of First Responders (FRs) fatalities and injuries remains. Reports show that advances in technology have not yet resulted in protecting FRs from injuries, health impacts, and odorless toxic gases effectively. Currently, there are emerging technologies that can be exploited and applied in emergency management settings to improve FRs protection. The aim of this paper is threefold: First, to conduct scenario analysis and situations that currently threat the first responders. Second, to conduct gap analysis concerning the new technology needs in relations to the pro…
El arte de la platería en la Concatedral de San Nicolás de Alicante
2020
The Co-cathedral of San Nicolás de Alicante still preserves an important treasure of pieces of silverware, ranging from the 17th to the 20th centuries, although the greatest development was known during the 18th century, with sumptuous commissions to the most prominent silversmiths both locally as at regional and national level. In this way, it can be said that the Alicante trousseau is a good example of a temple that, once built, focuses its efforts on the collection of silverware objects that enhance the cult and its ceremonies.
Anästhesie bei Patienten mit Porphyrie
2019
Die Porphyrien sind eine Gruppe vorwiegend hereditarer Stoffwechselstorungen der Hambiosynthese. Die Betreuung eines Patienten mit akuter Porphyrie ist eine interdisziplinare Herausforderung, bei der die Anasthesie eine koordinierende Funktion erfullt. Da es fur die Porphyrien bislang keine kausale Therapie gibt, richtet sich das Vorgehen im akuten Schub nach dem klinischen Bild. Im anasthesiologischen Umfeld ist insbesondere auf die Verwendung „sicherer“ Medikamente zu achten!
Komplikationen und Spätfolgen von Thrombosen
2014
Bei einer Lungenembolie tritt ein partieller oder vollstandiger Verschluss der Lungenarterien zumeist als direkte Folge einer Venenthrombose auf. Bei etwa 1/3 aller venosen thromboembolischen Ereignisse handelt es sich um eine Lungenembolie.

Pourquoi l’urologue doit s’intéresser à l’immunothérapie, quelles sont les indications établies en 2018 et celles en perspectives ?
2018
Resume L’immunotherapie est un concept ancien en oncologie, qui consiste a exploiter l’immunite innee antitumorale comme traitement anti-cancereux. Tandis que les premieres immunotherapies consistaient a stimuler globalement le systeme immunitaire (interleukine, interferon), l’immunotherapie « moderne » consiste a bloquer les mecanismes par lesquels les cellules cancereuses parviennent a echapper a l’immunite antitumorale, pour que les cellules du systeme immunitaire puissent les detecter et les eliminer. Deux voies permettant a la cellule tumorale d’echapper au systeme immunitaire ont ete identifiees : la voie de PD1 et CTLA4 qui sont les cibles des principales molecules faisant l’actualit…
Models of Corporeality and Controversies Around Puberty
2020
This chapter investigates the plurality of models proposed by medicine to observe the body between childhood and adolescence during the twentieth century. Models vary if the approach is anatomo-clinical, bio-psycho-social, photographical, or endocrinological. However, all these approaches aimed not only to better understand the pubertal process but also to define what is the “true puberty” and what constitutes a deviation from its “normal” course, while legitimating medical intervention. The analysis of the American controversy on the precocious onset of puberty, at the end of the 1990s, reveals not only the types of changing bodies, but also the types of children and adolescents that are d…
