Despite increasing recognition of the relevance of biological cycling for Si cycling in ecosystems and for Si export from soils to fluvial systems, effects of human cultivation on the Si cycle are still relatively understudied. Here we examined stable Si isotope (delta Si-30) signatures in soil water samples across a temperate land use gradient. We show that - independent of geological and climato
Popular Abstract in Swedish Växter är en av den största grupperna av organismer på jorden. Den här gruppen av organismer kan syntesisera kolhydrater med solenergi. I växter används en stor del av kolhydraterna till att bilda förnyelsebara polysackarider som sedan används för att bygga upp vedstrukturer. Den mest kända växtpolysackariden är cellulosa som består av långa kedjor av glukos. Den näst mHemicellulose is the second most abundant group of renewable polysaccharides. Mannans can be found as the major hemicellulose in softwood and as storage polysaccharides in a range of plants. In this work, structural and functional characterisations of family 5 and 26 endo-1,4-b-mannanases (b-mannanases) have been performed. These families belong to the large and diverse glycoside hydrolase clan A,
Popular Abstract in Swedish Dieselmotorn lanserades för mer än ett sekel sedan och är nu den mest använda motorn inom Europas transportsektor. Detta beror framför allt på dess låga bränsleförbrukning och höga effekt. Avgasutsläppen är dieselmotorns största nackdel eftersom dessa biprodukter från förbränningen har negativa effekter både på folkhälsan och miljön. Därför regleras utsläppen genom lagsDiesel engines are widely used as powertrain solutions for transportation vehicles. Their low fuel consumption and high performance make them attractive, however, their associated pollutant emissions is a major drawback which represent a hazard for public health and the environment. Therefore, the concentrations of the major pollutant species are regulated. Soot, which to a large extent consists
Popular Abstract in English In the modern world of today, we are surrounded with many electronic devices which offer previously unseen performance. These devices constitute a large part of the everyday consumer electronics such as laptops, tablets, smart phones, etc., but are also used in wide variety of domains such as automotive industry, avionics, medicine, etc. The constant demand for high perIncreasing soft error rates in recent semiconductor technologies enforce the usage of fault tolerance. While fault tolerance enables correct operation in the presence of soft errors, it usually introduces a time overhead. The time overhead is particularly important for a group of computer systems referred to as real-time systems (RTSs) where correct operation is defined as producing the correct re
We report on multiblock copolymers consisting of highly sulfonated hydrophilic poly(arylene sulfone) (SPAS) blocks combined with hydrophobic poly(arylene ether sulfone) (PAES) blocks. Dithiol-terminated precursor blocks of sulfonated poly(arylene thioether sulfone) (SPATS) were first prepared via polycondensations involving a novel tetrasulfonated dichlorotetraphenyldisulfone monomer, followed by
Narratological studies have quite frequently focused upon linguistic structures, considered to be paradigmatic cases of narrativity, whereas pictorial signs (such as icons and symbols) or indices have received comparably much less attention. In this paper, however, I intend to outline some basic and regularly occurring narrative aspects of pictures and non-pictorial objects. As a point of departu
This report presents a meticulous review of the background of today’s flow-based society and its vulnerability. Furthermore, there is a discussion about how to define flow-based disruption risks, and how their consequences, including the domino effects, can be described. Also the theory areas, addressing this kind of risks, are treated in this report. The modern society of today is, to a great ext
Background: Computed tomography (CT) scans are routinely performed in positron emission tomography (PET) and single photon emission computed tomography (SPECT) examinations globally, yet few surveys have been conducted to gather national diagnostic reference level (NDRL) data for CT radiation doses in positron emission tomography/computed tomography (PET/CT) and single photon emission computed tom
In relation to international obligations, under the Paris Climate Agreement and as a member state of the EU, Austria is expected to drastically cut carbon emissions over the coming years. In order to achieve this goal, measures to reduce emissions have to be taken in all sectors of the national economy. In this context it is interesting to note that to date it is widely unknown how much emissions
AimHirschsprung's disease is a congenital disorder requiring surgery. Most children operated on for Hirschsprung's disease experience postoperative bowel dysmotility. Although various food is known to influence bowel motility, evidence of diet's role and dietary guidelines in treatment of bowel dysfunction in Hirschsprung's disease is lacking. The aim was to explore parental experiences of dietary
Society is highly dependent on services such as electricity, communication, and transportation. Furthermore, the critical infrastructures (CIs) that provide these services are highly interdependent through a number of physical, economic and organizational links. In this context, a holistic perspective on risk is essential to avoid suboptimal interventions and risk-related blind spots. Here, fragme
The electricity prices in Sweden and Europe during 2022 have reached very high levels. The main reason for this being the war in Ukraine, which has led to a decreased availability for gas. During summer, the electricity prices reached extreme levels when meteorological and hydrological factors worsened the situation on the electricity market. The highest daily electricity price on the Nordic marke
Blue diode lasers emitting 5 mW continuous-wave power around 400 nm have recently become available. We report on the use of a blue diode laser together with a 30 mW red diode laser for sum-frequency generation around 254 nm. The ultraviolet power is estimated to be 0.9 nW, and 35 GHz mode-hop-free tuning range is achieved. This is enough to perform high-resolution ultraviolet spectroscopy of mercu
Prison library operation is an area which rarely gets attention from the public nor in research and is a niche within library operation which historically has fallen behind other types of library operations. In this master’s thesis we aim to shed light upon the operation of prison libraries in Sweden by investigating the access of the incarcerated to libraries and what reading promotion activities
Brottet vållande till annans död kännetecknas av att en persons agerande lett till någons död utan att detta varit avsiktligt eller kontrollerat från start till slut. För att kunna konstatera att detta agerande varit så pass klandervärt att det faller under straffrättsligt ansvar har domstolen att ta ställning till huruvida en otillåten risk har företagits. Vad som utgör ett otillåtet risktagande To cause someone’s death by mistake can bring criminal liability. For this mistake to be punishable, the court must decide whether an unacceptable risk has been taken. This assessment, however, is surrounded by difficulties when applied in the healthcare system. In medical decision-making, science and proven experience serve as a benchmark for acceptable actions. This essay aims to examine how th
An often-forgotten group in the discussion of information access is inmates. This group often lack access to internet and other forms of technology. This is a task that libraries are equipped to handle, but collaboration between libraries and prisons is lacking. In order to deepen the knowledge about prison libraries, this paper thoroughly describes research on their services to open up for improv
