In this paper we present the recent improvements for optically stimulated luminescence dosimetry using ordinary salt (NaCl). It is shown that the dosimetric properties of NaCl may be improved by compressing the salt grains to solid pellets. With a linear dose response in, at least, the region <100 mGy, a zero background signal (when pre-bleached) and a minimum measurable dose of 10-20 μGy and high
As the hardest tissue formed by vertebrates, enamel represents nature's engineering masterpiece with complex organizations of fibrous apatite crystals at the nanometer scale. Supramolecular assemblies of enamel matrix proteins (EMPs) play a key role as the structural scaffolds for regulating mineral morphology during enamel development. However, to achieve maximum tissue hardness, most organic con
In the Western world, gender/sex is traditionally viewed as binary, with people falling into one of two categories: male or female. This view of gender/sex has started to change, triggering some resistance. This research investigates psychological mechanisms underlying that resistance. Study 1 (N = 489, UK) explored the role of individual gender identification in defense of, and attempts to reinfo
Cross-border regions are characterised by many inherent challenges. Such challenges can include differences in languages, cultures, currencies, markets, labour market conditions, political visions and priorities, governance structures – to name but a few. Greater Copenhagen1 is no different in terms of the challenges it faces as a cross-border region.The aim of this study is to investigate the pos
Background: Intravenous ferric carboxymaltose has been shown to improve symptoms and quality of life in patients with chronic heart failure and iron deficiency. We aimed to evaluate the effect of ferric carboxymaltose, compared with placebo, on outcomes in patients who were stabilised after an episode of acute heart failure. Methods: AFFIRM-AHF was a multicentre, double-blind, randomised trial don
Within the project LATERES COCTILES early fired bricks have been the objectof a multifaceted investigation. One aim has been to elucidate the mechanisms behind the diffusion of this innovation. An inventory of Hellenistic and early Roman fired bricks around the Mediterranean resulted in an archaeological database comprising 276 brick contexts. Network analysis was applied to these data using a two
Skogar täcker ca 31% av jordens landyta och lagrar stora mängder kol i biomassa och i marken. I klimatavtalet från Paris 2015 lyfts skogars roll som sänkor och reservoarer av kol fram och undertecknande länder uppmanas att implementera strategier för hållbart skogsbruk som ytterligare förstärker skogars roll som sänkor av växthusgaser. Ett aktivt skogsbruk påverkar klimat och miljö på många olika Forest ecosystems cover 31% of the terrestrial land area and store large amounts of carbon in biomass and in soils. The 2015 Paris Agreement recognizes the importance of sinks and reservoirs of greenhouse gases (GHGs) in forests and the importance of enhancing them through sustainable forest management policies. Managing forests for climate mitigation purposes is, however, complex since management
Deliberate self-harm behavior (DSH) can have profound effects on a person’s quality of life, and challenges the health care system. Even though DSH has been associated with aggressive interpersonal behaviors, the knowledge on DSH in persons exhibiting such behaviors is scarce. This study aims to (1) specify the prevalence and character of DSH, (2) identify clinical, neurocognitive, psychosocial, a
Due to the significant increase in pediatric trunk computed tomography (CT) examinations, there is a need for a reliable approach of conducting effectivedose estimate for such procedures. The current study is based on two dosimetric anthropomorphic phantoms representing a 1-year and a 5-year old child. Effectiveand equivalent tissue doses from CT examinations of the trunk were determined by thermo
Establishing diagnostic reference levels (DRLs) in a big country is complicated due to differences in radiological practice between different regions. In 2009-2014, a dose survey was performed in six Russian regions. Based on the results of the survey, preliminary DRLs for conventional X-ray examinations were established on a national level. Additionally, the local authorities were granted the pos
