Denna avhandling behandlar två essentiella ting, vatten som är grundläggande för allt liv på jorden och kväve, vilket är ett grundämne som återfinns i varje protein och DNA. Liksom allt annat, måste dessa ämnen hålla en lagom nivå i cellen. För att klara variationer i tillgänglighet av dessa ämnen, har alla livsformer hittat sätt att påverka upptag och frisättning av dem. För att realisera detta pMajor intrinsic proteins, also referred to as aquaporins (AQPs) are localized in membranes of all domains of life to increase the permeability to water or other small, polar molecules. Several monophyletic groups can be discerned in this large and divergent protein superfamily. Members within these subfamilies commonly show a similar substrate selectivity established by conserved filters. Comparis

Cultural and creative activities are today described as central to regional and urban development by politicians and governments. Creative city policies are often aiming at economic benefits for the city itself, and there are normative purposes with many research studies as well as projects undertaken (Eckardt 2005; Markusen and Gadwa 2010; Kovacs 2011). Creative city policy is often oriented towa

In this study, bread was baked with and without the addition of α-amylase. Starch was extracted from the baked bread and its molecular properties were characterized using 1H NMR and asymmetric flow field-flow fractionation (AF4) connected to multi-angle light scattering (MALS) and other detectors. The approach allows determination of molar mass, root- mean-square radius and apparent density as wel

In acts of memorialisation, the objects that ”help” people get into contact with (their memory of) the deceased – like gravestones, personal collections of the deceased’s paraphernalia, objects placed at sites of sudden death, etc. – are often strictly regulated, differently in different cultures. At ”wrong” spots in the urban environment for instance, memorial places can thus be regarded as highl

This presentation investigates animals’ place in the contemporary human cemetery. It will do this by looking at what types of animals that are allowed to take place in the cemetery; both above and below the ground, physically as well as symbolically. The aim is to shine light on the various ways that animals are used and experienced in the cemetery, and to explore how this both reflects our changi

Single crystals of ludwigite Cu2MnBO5 were synthesized by flux growth technique. The detailed structural and magnetic characterizations of the synthesized samples have been carried out. The cations composition of the studied crystal was determined using X-ray diffraction and EXAFS technique, the resulting composition differ from the content of the initial Mn2O3–CuO components of the flux. Magnetic

Where and how new industrial paths emerge are much debated questions in economic geography, especially in light of the recent evolutionary turn. This article contributes to the ongoing debate on path creation with a new analytical framework that specifies the formation of generic resources in embryonic industries. It suggests that path creation processes are not only conditioned by preexisting reg

This paper examines the effect of the onset of Type 1 Diabetes Mellitus (T1DM) before 15 years of age on labor market outcomes and contributes to the literature on effects of childhood health on adult socioeconomic status. Using national Swedish socioeconomic register data 1991–2010 for 2485 individuals born 1972–1978 with onset of T1DM in 1977–1993, we find that T1DM in childhood has a negative e

This paper continues the discussion in a previous paper [Saeidpour and Wadsö doi:10.1016/j.cemconres.2016.02.003] where a clear effect of sorption hysteresis was seen in moisture diffusion coefficients for cement-based materials. Coefficients with vapor content as potential (Dv) had different values depending on whether the sample was in absorption or in desorption. In this paper we recalculate th

The glucose view of self-control posited glucose as the physiological substrate of self-control “resource”, which results in three direct corollaries: 1) engaging in a specific self-control activity would result in reduced glucose level; 2) the remaining glucose level after initial exertion of self-control would be positively correlated with following self-control performance; 3) restoring glucose

Background Physical activity (PA) in childhood is associated with musculoskeletal benefits while the effect on fracture risk is yet to be determined. The aim of this study was to evaluate whether extension of a PA intervention leads to improvement in musculoskeletal traits with an accompanied reduced fracture risk. We hypothesized that the PA program would have beneficial effects in both sexes, bu

This paper assesses the intergenerational effect of immigrant parents’ incorporation experiences, measured as time in Sweden, on the educational performance of their children, using full Swedish population registry data for 22 cohorts. Employing family fixed-effects, we examine final course grades and national standardized test scores in Swedish and math by parents’ country of origin. Results show

In this study the effect of the application of pulsed electric fields as pre-treatment before air drying of basil leaves at 50 °C was investigated. The parameters of the electric treatment were designed in such a way that they either (i) electroporated the tissue reversibly (tissue remains viable) and without electroporating the guard cells in the stomata complex (65 pulses of 600 V/cm, 120 μs pul

A gas bubble under the influence of an ultrasonic field so strong to destroy any material due to high pressures and temperatures reached during the collapse is the topic of the present paper. In the current work, simulations have been performed to describe the radial dynamics of a gas (argon) bubble being strongly forced to periodic oscillation in a highly viscous liquid like aqueous sulfuric acid

The underlying mechanisms for the effect of proteins on appetite regulation, especially in presence of variable macronutrient composition, are not fully elucidated. The present study investigated the absorption kinetics of proteins after co-ingestion with the other macronutrients and examined the impact of circulating amino acids on appetite and satiety-related gut hormones. A randomized, within-s

Colour vision — the ability to discriminate spectral differences irrespective of variations in intensity — has two basic requirements: (1) photoreceptors with different spectral sensitivities, and (2) neural comparison of signals from these photoreceptors. Major progress has been made understanding the evolution of the basic stages of colour vision–opsin pigments, screening pigments, and the first

This paper explores an emerging discourse at the UNFCCC level - the integrated landscape approach discourse, which brings new understandings of how to approach forests in a climate change nexus. Its proponents argue that forestry, agriculture and other land uses cannot be seen in isolation, but need to be integrated into a single management process. I apply argumentative discourse analysis (Hajer,

A theory to describe deforming moist paperboard in environments where both temperature and pressure change significantly during a short period of time is presented. Paperboard is viewed as an orthotropic triphasic porous medium consisting of fibers, bound water and moist air. Furthermore, the moist air is considered as a mixture of two miscible gases, namely dry air and water vapor. A two–scale hy

This paper investigates the place of animals in the contemporary Swedish human cemetery. It does this by looking at how animals are admitted to cemeteries – alive and dead, above and below ground, physically as well as symbolically. The aim is to shed light on the various ways that animals are experienced and treated in the cemetery, and to explore how this both reflects our changing attitudes to
