Upper bounds for the tightness of the $$G_\delta $$-topology
2021
We prove that if X is a regular space with no uncountable free sequences, then the tightness of its $$G_\delta $$ topology is at most the continuum and if X is, in addition, assumed to be Lindelof then its $$G_\delta $$ topology contains no free sequences of length larger then the continuum. We also show that, surprisingly, the higher cardinal generalization of our theorem does not hold, by constructing a regular space with no free sequences of length larger than $$\omega _1$$ , but whose $$G_\delta $$ topology can have arbitrarily large tightness.
A survey of dentists' practice in the restoration of the shortened dental arch.
2010
Objectives: The aim of this survey was to determine how a sample of dentists working in general dental practice in the UK sought to restore the mouths of patients who had shortened dental arches (SDAs). Study design: A survey was conducted over a period of six months on four commercial dental laboratories. Cases of SDAs comprising the anterior teeth and 2 to 4 premolars were examined; dental prescriptions were scrutinized and a special data collection form was completed accordingly. Results: A total of 140 SDA cases were examined. Most of these cases were for mandibular SDAs (88.6%). Of the recorded SDA cases, 67.2% were restored by cobalt-chromium based removable partial dentures (RPD); 25…
Adequate Training and Multidisciplinary Support May Assist Pediatricians in Properly Handling and Managing Gender Incongruence and Dysphoria.
2022
What we call “sexual identity” refers to the complex relationship between biological sex, gender identity and role, and sexual orientation.1 “Gender identity” means the unified and persistent perception of oneself as belonging to the male or the female gender or ambivalent. For many, gender identity coincides with sexual identity; traditional culture has long provided for the definition of only 2 genders, corresponding to the 2 biological sexes. The person with gender incongruence experiences a disharmony between biological aspects and gender identity, with the constant awareness that he or she belongs to the opposite gender and is imprisoned in a body that does not represent him or her. Ge…
The effect of long context exposure on cued conditioning and c-fos expression in the rat forebrain
2004
The c-fos expression was used to study the neural substrates of the cued fear conditioning acquisition, preceded by a short exposure versus a long exposure to the conditioning context. A long-context exposure (either during the night or during the day) prior to conditioning, was associated with low freezing in the learning test. Differences in the c-fos expression of CA1, CA3, BL Amygdala, LS and BNST were found between the short- or long-context groups with a pre-exposure before cued conditioning. Ce Amygdala showed no differences in the c-fos expression labeling. We reported the hippocampal c-fos activation during the cued fear conditioning acquisition. Specifically, the CA1 activation co…
«Formalistic obscurantism»? An attempt to decipher the curriculum in social studies
2021
I 2020 trådte det nye læreplanverket, Kunnskapsløftet 2020, i kraft i norsk skole. I artikkelen har vi valgt samfunnsfaget i ungdomsskolen som eksempelstudium. Vi presenterer en detaljert, empirinær analyse av forholdet mellom kompetansemål, kjerneelementer og tverrfaglige tema i læreplanstrukturen for skolefag, samt forholdet mellom disse og overordnet del. Eksempelet er avgrenset til samfunnsfaget på ungdomsskolen, og basert på det forskriftsfestede planverket og den digitale støttemodulen. Funnene i denne delen av analysen gir praktisk kunnskap om læreplanene som er helt sentral for lærerutdannere og lærere, og som har overføringsverdi (og relevans) for fagdidaktikk for andre skolefag. I…
Barns tilgang til erfaringer som er relevante for samfunnsfag
2022
Praktiske erfaringer er en viktig kilde til sakkunnskap i samfunnsfag på småskoletrinnet. 97 prosent av elevene har 2–5 års barnehageerfaring når de begynner på skolen, og innholdet i barnehagehverdagen har betydning for skolestarternes erfaringsrikdom. Styringsdokumentene legger premisser for barns tilgang til slike erfaringer, og artikkelens problemstilling er: I hvilken grad legger planverket til rette for faglig progre-sjon mellom nærmiljø og samfunn i barnehagen og samfunnsfag på småskoletrinnet? Materialet er hentet fra Rammeplan for barnehagen (RP17) og Læreplan i samfunnsfag (LK20). For å sammenlikne så forskjellige plandokumenter har jeg utviklet et analyse-verktøy med utgangspunkt…
Self-similar focusing with generalized devil's lenses
2011
[EN] We introduce the generalized devil's lenses (GDLs) as a new family of diffractive kinoform lenses whose structure is based on the generalized Cantor set. The focusing properties of different members of this family are analyzed. It is shown that under plane wave illumination the GDLs give a single main focus surrounded by many subsidiary foci. It is shown that the total number of subsidiary foci is higher than the number of foci corresponding to conventional devil's lenses; however, the self-similar behavior of the axial irradiance is preserved to some extent.

Losing an Unexpected Throne: Deposing Second Sons of the Stuart Dynasty
2017
Two second sons of the Stuart dynasty who came as unexpected heirs to the throne lost their crown in depositions . Both of these kings, Charles I and James II , had a strong belief in a personal kingship over loyal subjects, which was at odds with the English concept of King-in-Parliament and the possibilities for subjects to participate in the rule of the kingdom. Charles I and James II lacked the natural confidence of born kings, and both tried to overcome this deficiency by overemphasizing their royal dignity. In doing so, they never realized that the generally accepted idea of a divine right of kings was to be articulated and represented, but not implemented in politics.

From the Golgi-Cajal mapping to the transmitter-based characterization of the neuronal networks leading to two modes of brain communication: Wiring a…
2007
After Golgi-Cajal mapped neural circuits, the discovery and mapping of the central monoamine neurons opened up for a new understanding of interneuronal communication by indicating that another form of communication exists. For instance, it was found that dopamine may be released as a prolactin inhibitory factor from the median eminence, indicating an alternative mode of dopamine communication in the brain. Subsequently, the analysis of the locus coeruleus noradrenaline neurons demonstrated a novel type of lower brainstem neuron that monosynaptically and globally innervated the entire CNS. Furthermore, the ascending raphe serotonin neuron systems were found to globally innervate the forebrai…
