Low-temperature cathodo- and photoluminescence connected with the F and F+ centers (oxygen vacancies in different charge states) and bivacancies have been investigated in MgO single crystals preliminarily irradiated by 230-MeV 132Xe ions with varying fluence (up to 1014 ions/cm2). The cathodoluminesence bands (result of decomposition into Gaussians) related to the F, F+ and P centers have intensif

Background & aims: Tea has been shown to be associated with reduced risk of several diseases including cardiovascular diseases, stroke, metabolic syndrome, and obesity. However, the results on the relationship between tea consumption and bladder cancer are conflicting. This research aimed to assess the association between tea consumption and risk of bladder cancer using a pooled analysis of pr

We employed the VISTA near-infrared YJKssurvey of the Magellanic System (VMC) to analyse the Y, J, and Ks light curves of δCepheid stars (DCEPs) in the Large Magellanic Cloud (LMC). Our sample consists of 4408 objects accounting for 97 per cent of the combined list of OGLE IV and Gaia DR2 DCEPs. We determined a variety of period-luminosity (PL) and period-Wesenheit PW relationships for Fundamental

We study selection into lab experiments based on data from two cohorts of first-year university students. We combine two experiments: a classroom experiment in which we elicit measures of time and risk preferences, overconfidence, trust, reciprocity, altruism, and cognitive reflection and a recruitment experiment with four treatment conditions that randomly vary the information provided in the e-m

The planet is presently undergoing dramatic changes caused by human activities. We are living in the era of the Anthropocene, where our activities directly affect all living organisms on Earth. Insects constitute a major part of the world’s biodiversity and currently, we see dwindling insect biomass but also outbreaks of certain populations. Most insects rely on chemical communication to locate fo

Insects are able to detect a plethora of olfactory cues using a divergent family of odorant receptors (ORs). Despite the divergent nature of this family, related species frequently express several evolutionarily conserved OR orthologues. In the largest order of insects, Coleoptera, it remains unknown whether OR orthologues have conserved or divergent functions in different species. Using HEK293 ce

Epithelial ovarian cancer (EOC) is the most lethal gynecologic malignancy and has a unique metastatic route using ascites, known as the transcoelomic root. However, studies on ascites and contained cellular components have not yet been sufficiently clarified. In this review, we focus on the significance of accumulating ascites, contained EOC cells in the form of spheroids, and interaction with non

I tidigare forskning om narkotika har kvinnor oftast setts som offer och medhjälpare till män, men det finns relativt lite kunskap om hur kvinnor som begår narkotikabrott agerar och resonerar kring sina upplevelser. Syftet med denna rapport är att fånga hur kvinnorna själva förklarar hur och varför de började, fortsatte och i vissa fall slutade eller fortsatt att hantera narkotika.

The assessment of entrepreneurship education outcomes should move beyond a focus on firm creation and associated economic impact to consider a more nuanced view that pays attention to graduates and their entrepreneurial competencies. There is currently limited understanding to what extent entrepreneurial competencies developed through entrepreneurship education are applied in graduates’ subsequent

crataegi Germar, 1824. The first specimen was found in the city of Malmö in the southernmost province of Sweden in the beginning of October 2020, where one individual had taken shelter from a heavy morning rain on a house wall, together with several other beetle species. The species was subsequently sought after during late autumn and winter by sifting litter beneath putative host plants, but it c

The Sun sporadically produces eruptive events leading to intense fluxes of solar energetic particles (SEPs) that dramatically disrupt the near-Earth radiation environment. Such events have been directly studied for the last decades but little is known about the occurrence and magnitude of rare, extreme SEP events. Presently, a few events that produced measurable signals in cosmogenic radionuclides

Many studies have used the relative activities of extracellular enzymes associated with microbial carbon (C), nitrogen (N) and phosphorus (P) acquisition to infer the relative C vs. nutrient limitation of the microbial community. However, recent experimental and theoretical evidence has shown that the use of ecoenzymatic ratio to infer limiting microbial resources may be invalid. We added the two

Mosquitoes use olfaction as a primary means of detecting their hosts. Previously, the functional ablation of a family of Aedes aegypti olfactory receptors, the odorant receptors (ORs), was not sufficient to reduce host seeking in the presence of carbon dioxide (CO2). This suggests the olfactory receptors that remain, such as the ionotropic receptors (IRs), could play a significant role in host det
