Animals are thought to use achromatic signals to detect small (or distant) objects and chromatic signals for large (or nearby) objects. While the spatial resolution of the achromatic channel has been widely studied, the spatial resolution of the chromatic channel has rarely been estimated. Using an operant conditioning method, we determined (i) the achromatic contrast sensitivity function and (ii)
Purpose: This article aims to determine the prevalence of substance use among young festival-goers and the associations between preferences for different types of music and recent use of different types of licit and illicit drugs. Design/methodology/approach: The article is based on a cross-sectional survey of 1,787 young adults attending a music festival in Denmark. Associations between preferenc
Analyzing the progression of Alzheimer's disease (AD) is challenging due to lacking sensitivity in currently available measures. AD stages are typically defined based on cognitive cut-offs, but this results in heterogeneous patient groups. More accurate modeling of the continuous progression of the disease would enable more accurate patient prognosis. To address these issues, we propose a new mult
During amino acid starvation the Escherichia coli stringent response factor RelA recognizes deacylated tRNA in the ribosomal A-site. This interaction activates RelA-mediated synthesis of alarmone nucleotides pppGpp and ppGpp, collectively referred to as (p)ppGpp. These two alarmones are synthesized by addition of a pyrophosphate moiety to the 3 position of the abundant cellular nucleotide GTP and
Detecting the entire repertoire of tumor-specific reactive tumor-infiltrating lymphocytes (TILs) is essential for investigating their immunological functions in the tumor microenvironment. Current in vitro assays identifying tumor-specific functional activation measure the upregulation of surface molecules, de novo production of antitumor cytokines, or mobilization of cytotoxic granules following
“Wet” eldercare facilities for people who age with long-term substance use problems and complex needs exist in several countries. Residents are accepted as active users of alcohol and drugs, and while the media has presented the permissive policies of the facilities in a positive light, others have described these policies as harmful. The aim of this article is to analyze residents' and staff memb
Background and Objectives: With an ageing population, the number of older persons with substance use problems, particularly problematic alcohol use, is increasing. Despite growing recognition of the negative consequences of problematic alcohol use on older persons, there is a dearth of knowledge about the alcohol use profiles and the dimensionality of alcohol problems in older people. Moreover, l
Introduction: Debilitating clinical complications in von Willebrand disease (VWD) can affect health-related quality of life (HRQoL), increase healthcare costs and cause long-lasting consequences. However, the magnitude of these burdens needs to be more fully explored. Aim: To estimate the prevalence and burden of clinical complications, the impact on HRQoL and the economic burden associated with V
Nanostructures of conventional metals offer manipulation of light at the nanoscale but are largely limited to static behavior due to fixed material properties. To develop the next frontier of dynamic nano-optics and metasurfaces, this study utilizes the redox-tunable optical properties of conducting polymers, as recently shown to be capable of sustaining plasmons in their most conducting oxidized
Searches for new physics (NP) at particle colliders typically involve multivariate analysis of kinematic distributions of final state particles produced in a decay of a hypothetical NP resonance. Since the pair-production cross-sections mediated by such resonances are strongly suppressed by the NP scale, this analysis becomes less relevant for NP searches for masses of the BSM resonance above 1 Te
Popular Abstract in Swedish Dagens samhälle är mycket beroende av fordonsbränslen och kemikalier som producerats av råolja. Framtidens tillgång på råolja är oviss, det enda som är säkert är att det är en ändlig resurs. Användningen av olja bidrar dessutom till koldioxidutsläpp till atmosfären. För att säkra framtida tillförsel av energi och kemikalier till samhället och för att uppnå ett mer klimaMany scientists believe that the oil production will peak in the near future, if the peak has not already occurred. Peak oil theories and uncertain future oil deliveries have stimulated interest in alternative sources of fuel and chemicals. This interest has been enhanced by concerns about energy security and about the climate change caused by emissions of carbon dioxide. The result has been incre
Distansavtalslagen har genomgått flera lagändringar och utvecklats i samband med digitaliseringens utbredning. Det har medfört en ökad användning av digitala tjänster och varor med digitalt innehåll. Utformningen av distansavtalslagens konsumentskyddande bestämmelser har även påverkats av moderniserade EU-rättsakter, som införts i syfte att harmonisera bestämmelserna för den gränsöverskridande han
Energy efficiency in buildings can be understood elaborately by evaluating its operational and embodied energy. Embodied energy is the sum of all the energy that is used to produce materials in a building construction. This study assesses various building parameters e.g. U-value of the materials, Window to Floor Area Ratio (WFR), location, etc. that affect the operational and embodied energy and u
The conflict between humans and elephants (HEC) in Sri Lanka is severe. Due to habitat fragmentation and resource reduction elephants increasingly roam in areas with human settlements. These human-elephant interactions often lead to losses on both sides, which should be prevented. The Department of Wildlife Conservation (DWC) holds all decision-making powers which enables them to implement solutio
The development of electrical circuit boards is increasing and the time spent in the development stage can be quite long. The thesis has tried to shorten the time spent developing new electrical circuit boards, by first finding a common denominator for efficiency losses in the development process and then implementing an example solution. The problem identified was the lack of attention towards pr
The aim of this paper was to establish sources for microplastic fibres and fragments based on the presence of specific colours (I) within different land use classes and (II) in relation to the location of wastewater treatment plants. Most of the colours did not result in significantly different counts between the land use classes, except for black fragments, which resulted in significantly higher
The bulk of Norwegian offshore oil and gas platforms are self-sustained with energy, burning a portion of the extracted gas in turbines to power production. Replacing this energy with electricity from renewables – electrifying – has been put forward as a way to quickly slash domestic emissions. This, all while retaining and expanding fossil fuel production, whose lion’s share of emissions stem not
As the urgency of addressing climate change intensifies, innovative financial instruments are needed to align capital markets with sustainability goals. This thesis explores the concept of the \textit{transition linker}, a hypothetical performance-linked sovereign bond whose cash flows depend on greenhouse gas emission reduction targets, as outlined in its Nationally Determined Contributions under
Retroaktivitetsförbudet inom skatterätten instiftades 1980 och innebär ett förbud mot att införa skattelag med retroaktiv verkan. Inspirationen kom från straffrätten i vilken principen om förbud mot retroaktiv lag länge hade varit förhärskande. Retroaktivitetsförbudet har med sin ställning som grundlag hög formell status i det svenska rättsväsendet vilket borde borga för att både domstolar och la
