OBJECTIVES: The aim of this study was twofold: (i) to evaluate the air levels of N-nitrosamines in the Swedish rubber industry and (ii) to estimate the risk of symptoms and changed levels of immunologic markers in relation to these levels.METHODS: Using adsorption tubes, we collected samples of N-nitrosamines in the breathing zone of 96 rubber workers and analyzed them with liquid chromatography t

During the stress response adrenal medullary chromaffin cells release catecholamines to the bloodstream. Voltage-activated calcium channels present in the cell membrane play a crucial role in this process. Although the electrophysiological and pharmacological properties of chromaffin cell calcium channels have been studied in detail, the molecular composition of these channels has not been defined

Wind power is seen by many observers as an important part of the transition to a sustainable energy system, since it does not contribute to the environmental problems connected with dominating energy forms such as fossil fuel, nuclear power and large-scale hydro power. At the same time wind power has some characteristics that makes it a special challenge for land use planning. In Sweden, where win

Popular Abstract in Swedish Vanlig bagerijäst, Saccharomyces cerevisiae, används i storskalig etanol framställning från majs och sockerrör. Användandet av dessa råvaror för etanolproduktion konkurerar dock med framställning av spannmål för föda och djurhushållning. Den här avhandlingen har syftat till att få bagerijäst att använda sockerarten xylos, som finns i stora halter i restprodukter från skBaker’s yeast, Saccharomyces cerevisae, has been engineered to utilize the pentose sugar xylose present in lignocellulose biomass for the production of ethanol. Currently ethanol production from xylose is slow which limits the implementation of said strains in industrial production. This thesis describes the investigation of several metabolic aspects that control the rate of xylose utilization by

This doctoral thesis examines the encounter between the dead and the living within 19th and 20th century landscape cemeteries. It shows how the relationship unfolds through the materiality and practices occurring within them.Landscape cemeteries were established from the late 18th century and with their garden-inspired design, location outside of the city and increasing secular administration were

Forest leaf area index (LAI), is an important variable in carbon balance models. However, understory vegetation is a recognized problem that limits the accuracy of sate I lite-estimated forest LAI. A canopy reflectance model was used to investigate the impact of the understory vegetation on LAI estimated from reflectance values estimated from satellite sensor data. Reflectance spectra were produce

Agriculture is interrelated with the socio-economic and natural environment and faces increasingly the problem of managing its multiple functions in a sustainable way. Growing emphasis is on adequate policies that can support both agriculture and sustainable development. Integrated Assessment and Modelling (IAM) can provide insight into the potential impacts of policy changes. An increasing number

Calbindin D-28k, a highly conserved protein with Ca2+-sensing and Ca2+-buffering capabilities, is abundant in brain and sensory neurons. This protein contains six EF-hand subdomains, four of which bind Call with high affinity. Calbindin D28k can be reconstituted from six synthetic peptides corresponding to the six EF-hands, indicating a single-domain structure with multiple interactions between th

The world is constantly changing, and business strategies are changing with it. Companies are offering new delivery options and technologies for customers globally when doing purchases. IKEA, a global furniture retailer, is expanding their touchpoints by opening retail stores in city centre locations in order to become more accessible. The ways customers travel in urban areas are more varied incl

Purpose - The collection-delivery points in Sweden are the main delivery method and facilitates a growing volume of parcel deliveries from e-commerce. As the model has been implemented on such scale in the country, the negative externalities previously outlined in the literature can get magnified in the context of the Swedish consumers. It is important to gain a deeper understanding on every aspec

The aim of this thesis is to explore the relative importance of the eight psychological Active Innovation Resistance (AIR) barriers, from the new typology of AIR barriers developed from Talke and Heidenreich in 2014, on the consumer’s intention to adopt or buy circular fashion products. Moreover, this thesis examines whether the socio-demographic factors of age, employment status, and educational

The Swedish national library has collected nearly all Swedish printed materials for more than three centuries. Regarding digital material, the digital legal deposit act was enacted about nine years ago. According to the law, a selection of digital publications must be sent to the national library for preservation. The Swedish digital legal deposit act has been heavily criticized, mostly because it

Shared Reading is a reading promotion concept that originated in the United Kingdom and has, over the past three years, begun to engage various actors in Sweden including the Swedish hospital library. In the use of the method, health-promoting effects have also been identified, which is why Shared Reading has interested research in so-called medical humanities in a Swedish as well as an internatio

This thesis investigates the effect of visible articulatory movements on speech comprehension in L1 and L2 listeners of Swedish. Previous research found faciliatory effects on speech perception when speech was presented audiovisually in various settings and under diverse listening conditions for both L1 and L2 listeners. However, it is still not investigated thoroughly, how L2 proficiency affects

Denna studie utgår från två miljökampanjer som skapats med grund i Cacioppo & Pettys (1984) “Elaboration likelihood model”, som kortfattat menar på att vi kan processa ett meddelande på antingen ett s.k perifert- eller centralt plan. Utifrån detta har vi skapat två kampanjbilder med fokus på miljöproblem, där den ena innehåller perifera- och den andra centrala budskap. Dessa användes för att uThis study stems from two environmental campaigns which have been created with Cacioppo & Pettys (1984) “Elaboration likelihood model” as a foundation, which in summary says that we can process a message through a peripheral- or central mindset. Using this as a starting point, we created two campaigns that focus on environmental issues, one contains peripheral- and the other central cues. In o

Vindkraftverk är ett av samhällets främsta verktyg för en miljövänlig energiproduktion. Den konventionella designen av bladen är emellertid i stort sett oförändrad. Triblade är ny typ av design som har potentialen att revolutionera marknaden. Genom att använda en fackverksstruktur öppnar man för möjligheten att utforska andra materialval än de konventionella kol- och glasfibermaterial som anväIn the 21st century, wind power has emerged as a strong candidate in fulfilling societies goals of achieving carbon-free energy energy production. Windpower has evolved along with other technological developments, giving rise to larger turbines, but with the overall design trend remaining largely unchanged. Winfoor, a Swedish company based in Lund,aims to break that trend. With their new Triblade

The vehicle industry is making great strides in electric and hybrid technologies, representing a significant step towards reducing emissions from personal vehicles. In order to make the transition to new hybrid technologies as convincing as possible, well-functioning and smooth transitions between traditional combustion engines and electric motors are required. So-called mild hybrids enable a cos

Migration to wintering grounds is a process that a large proportion of songbirds perform every year. It has been suggested that there are differences in the migration performance between adults and juveniles due to the experience the former have over the latter, after having flown this journey before. The aim of this study was to analyse age differences regarding activity, energy deposits and depa
