An hypothesis is presented that provitamin D (dehydrocholesterol and/or ergosterol) can act as a UV-B receptor in plants and algae. We also propose that the proportions between provitamins D, previtamins D, and vitamins D (D2 and D3), after calibration, can be used to evaluate UV-B exposure of phytoplankton and terrestrial vegetation. This is the final, accepted and revised manuscript of this art

The progress made in the field of patents on pharmaceuticals the last fifteen years, has been of continuous change and adaptation. From the introduction of the TRIPS Agreement in 1995, where patents on pharmaceuticals became a necessity for all Member States of the WTO, to today, where a ratification of the TRIPS Amendment is ongoing, and might be a mean to enhance access to medicine for all peopl

At the same time as the right-wing extremist wind blowing across Europe, the frequency of hate crimes in Europe is on the rise. This paper investigates the relationship between hate crime and unemployment in the municipalities of Sweden. To protect individuals from being identified the hate crime data is left censored at the threshold of 19 reported hate crimes per municipality and year. The data

This paper investigates the performance differences between sustainable and unsustainable funds, measured by ESG rating, over the time period of January 2006 to December 2020 on OMX Stockholm. It also sheds light on the performance differences between unsustainable funds and unsustainable funds claiming to be sustainable, i.e. greenwashers. The paper uses Fama and French five-factor model and time

Studien är gjord för att öppna upp för användarmedverkan i designprocessen inom spelutveckling i försök att minska det antal avbrutna projekt som föreligger idag. Spelutveckling involverar för närvarande användaren sparsamt i utvecklings- processen. För att öka graden av involvering valde vi att kombinera participativ design och personas till en processbaserad arbetsmodell att undersöka. Vi beslut

Research data are complicated things. The question of whether they are things at all is of course contentious. Yet, even if we leave this issue aside for now, there are continuous debates - some would say struggles - over who owns the data, how to handle and describe it, how to store and share more of it and why, in short, who has which interest in it. It is also unclear when it is appropriate to

BACKGROUND: Long-term cognitive problems are common among elderly patients after surgery, and it has been suggested that inhalation anaesthetics play a role in the development of dementia. This study aims to investigate the hypothesis that patients with dementia have been more exposed to surgery and inhalational anaesthetics than individuals without dementia.METHODS: Using 457 cases from a dementi

The practice of using quantitative risk assessments (QRAs) for managing risks in land-use planning varies between countries. Some regulatory regimes are highly prescriptive in terms of explicit requirements on methodology, assumptions, modelling tools, input data, risk criteria, etc. Others require risk analyses to support decision-making without regulating the details. The present study seeks to

One of the most important factors governing durability of concrete structures is reinforcement corrosion, and to prevent degradation associated with it, it is desirable to use large concrete covers. However, if the concrete cover is increased, the majority of design methods will predict that the crack widths at the concrete surface increase significantly. This can be contradictory, since the same
