Hydrogels for Three-Dimensional Ionizing-Radiation Dosimetry

2021

Radiation-sensitive gels are among the most recent and promising developments for radiation therapy (RT) dosimetry. RT dosimetry has the twofold goal of ensuring the quality of the treatment and the radiation protection of the patient. Benchmark dosimetry for acceptance testing and commissioning of RT systems is still based on ionization chambers. However, even the smallest chambers cannot resolve the steep dose gradients of up to 30–50% per mm generated with the most advanced techniques. While a multitude of systems based, e.g., on luminescence, silicon diodes and radiochromic materials have been developed, they do not allow the truly continuous 3D dose measurements offered by radiation-se…

Analysis of the Potential of an Increase in Yeast Output Resulting from the Application of Additional Process Wastewater in the Evaporator Station

2019

This paper reports the results of an analysis of process wastewater streams in the context of an increase in yeast production. This research is based on the analysis of data from the biggest yeast factory in Europe. The research presented in this paper involves the analysis of the influence of direction of additional wastewater into the evaporator station on yeast production. In the process wastewater, nitrogen is mainly present in organic forms. The analysis reported in this paper involves the concentration of total nitrogen in wastewater streams, as it is the main parameter applied to determine the amount of wastewater that can be applied in agricultural fields. Directing additional waste…

First report on the helminthfauna of the yellow-necked mouse, Apodemus flavicollis, in the Iberian Peninsula

2016

Summary Information about the prevalence of helminth parasites of the yellow-necked mouse, Apodemus flavicollis, in the Iberian Peninsula is almost non-existent and there is no reliable data reported from Spain. Fourteen A. flavicollis from the Erro River valley (Navarre, Spain) were examined for endoparasites, between February 2001 and July 2002. Thirteen specimens (92.9 %) of the total sample were parasitized by at least one of the following six helminth species: one trematode (Corrigia vitta), one cestode (Taenia parva larvae) and four nematodes (Trichuris muris, Calodium hepaticum, Heligmosomoides polygyrus and Syphacia stroma). This is the first report about the helminthfauna of A. fla…

"I never gave up"

2019

Esports phenomena have grown rapidly in recent years, and so has research on the topic. Some of the research has also addressed esports fandom (see e.g. Taylor 2012). Nevertheless, studies comparing and contrasting how players and fans engage with the game and the esports based on that game are scarce. This study compares and contrasts how players and fans engage with playable game characters and esports players. The paper draws on previous research in fan studies, sports fandom and esports to examine the relationships of players and fans of the videogame Overwatch (Blizzard Entertainment 2016) with the fictional heroes of the game as well as with their favorite professional players in the …

Is Broad the New Deep in Environmental Ethics? A Comparison of Broad Ecological Justice and Deep Ecology

2016

I argue in this article that a theory of broad ecological justice or the extended capabilities approach, an interesting approach in contemporary environmental ethics, shares many of its core ideas with deep ecology and Arne Næss’s ecosophy T. The similarities between these approaches include the ambition to address the roots of environmental problems, emphasis on recognition and the criticism of oppressive structures, and a systemic orientation. Acknowledging these similarities illustrates the contemporary value of the deep ecology movement. It also helps to develop the theory of broad ecological justice further, especially in terms of bridging the gap between movements and theoretical disc…

Low-level environmental metal pollution is associated with altered gut microbiota of a wild rodent, the bank vole (Myodes glareolus)

2021

Mining and related industries are a major source of metal pollution. In contrast to the well-studied effects of ex-posure to metals on animal physiology and health, the impacts of environmental metal pollution on the gut mi-crobiota of wild animals are virtually unknown. As the gut microbiota is a key component of host health, it is important to understand whether metal pollution can alter wild animal gut microbiota composition. Using a combination of 16S rRNA amplicon sequencing and quantification of metal levels in kidneys, we assessed whether multi-metal exposure (the sum of normalized levels of fifteen metals) was associated with changes in gut microbiota of wild bank voles (Myodes glar…

Physical activity from adolescence to young adulthood: patterns of change, and their associations with activity domains and sedentary time

2021

Background Longitudinal studies demonstrate an average decline in physical activity (PA) from adolescence to young adulthood. However, while some subgroups of adolescents decrease activity, others increase or maintain high or low activity. Activity domains may differ between subgroups (exhibiting different PA patterns), and they offer valuable information for targeted health promotion. Hence, the aim of this study was to identify PA patterns from adolescence to young adulthood; also to explore the associations of (i) changes in PA domains and in sedentary time, (ii) sociodemographic factors, and (iii) self-rated health with diverging PA patterns. Methods The observational cohort study data …

Parents’ experiences of the transfer from pediatric to adult care for their adolescent or young adult children with chronic conditions: a systematic …

2014

Published version of an article in the journal: JBI Database of Systematic Reviews and Implementation Reports. Also available from the publisher at: http://dx.doi.org/10.11124/jbisrir-2014-1565 Open Access Review question/objective: The objective of this systematic review is to identify parents' experiences of adolescents and young adults (AYA) health care transfer from pediatric to adult care. 1. How do parents experience being prepared for the transfer from pediatric to adult care of their AYA with a chronic condition? 2. How do parents experience the event of transfer? 3. How does the type of chronic condition influence parents' experiences of AYAs' transfer from pediatric to adult care?…

Bladder tumours in children: An interesting case report of TCC with a partial inverted growth pattern.

2014

Bladder urothelial carcinoma is typically a disease of older individuals and rarely occurs below the age of 40 years. There is debate and uncertainty in the literature regarding the clinicopathologic and prognostic characteristics of bladder urothelial neoplasms in younger patients compared with older patients, although no consistent age criteria have been used to define "younger" age group categories. We report on a 16 years old girl with transitional cell carcinoma of the bladder with a partial inverted growth pattern who presented with gross hematuria. Ultrasonography revealed a papillary lesion in the bladder; cystoscopic evaluation showed a 15 mm papillary lesion with a thick stalk loc…
