The carbon sink potential of peatlands depends on the balance of carbon uptake by plants and microbial decomposition. The rates of both these processes will increase with warming but it remains unclear which will dominate the global peatland response. Here we examine the global relationship between peatland carbon accumulation rates during the last millennium and planetary-scale climate space. A p
Background: Vitamin K is a cofactor for proteins involved in cardiovascular health, bone metabolism and cancer. Measuring uncarboxylated prothrombin, also termed as “protein induced by vitamin K absence or antagonism for factor II (PIVKA-II)”, has been used to assess vitamin K status. High levels may indicate vitamin K deficiency. The aim of this study was to measure PIVKA-II and prothrombin time
The design of slender structures is often associated with a number of assumptions made by engineers in checking on the stability of the structure. Not seldom, these assumptions are rather uncertain. In the present paper the effects of the stiffness of different members on the bracing stiffness of timber structures is studied. Both full-scale laboratory testing and FE-modelling are employed here in
Joints in timber structures are particularly vulnerable to degradation due to their tendency to trap moisture. The mechanisms involved, and their effect on the moisture conditions of wood, are here investigated numerically. The horizontal member of a rail and post-type configuration is modelled numerically by a two-dimensional diffusion model with material properties for Norway spruce. Contact are
The longevity of timber structures in exposed outdoor environments is often perceived to be unreliable as compared with that of concrete and steel structures. This situation is exacerbated to some extent by the fact that the European commission for standardization (CEN) currently provides no quantitative method for service life assessment of timber structures. To counteract this, the present thesi
Det här är en avhandling om livsstilsbutiker och de handlare som driver dem. Livsstilsbutiker är affärer där olika produkter och tjänster erbjuds och gestaltas som helhetskoncept, ofta med hjälp av atmosfärskapande estetik. Med syftet att förstå hur livsstil görs till handelsföretagande beskriver och analyserar denna narrativa etnografi berättelser om och från livsstilsbutiker. Med utgångspunkt i This is a dissertation about life style boutiques and the shopkeepers who operate them. Lifestyle boutiques are shops where a variety of goods and services is offered and staged as an overall concept, often targeted to specific groups and tastes with atmosphere-creating aesthetics. Aiming to understand how lifestyle is made into retail enterprising, this narrative ethnography describes and analyse
To remain competitive in the field of manufacturing today, companies must constantly improve the automation loops within their production plants. This can be done by augmenting the automation applications with "smart services" such as supervisory-control applications or machine-learning inference algorithms. The downside is that these smart services are often hosted in a cloud infrastructure and t
Hairdressers are exposed to high levels of chemicals, including possible carcinogens. For dermal exposure, the skin protects against the uptake of chemicals and the protein filaggrin (encoded by FLG) has a key role in skin barrier function. This study investigated if variants of FLG previously linked to impaired skin barrier function, i.e. null mutations and copy number variation (CNV) alleles (CN
Reaction of the tridentate aminoalcohol phenol ligands 2,4-di-tert-butyl-6-(((2 hydroxyethyl)(methyl)amino)methyl)phenol (H2L1) and 2,4-di-tert-butyl-6-(((1-hydroxybutan-2-yl)amino)methyl)phenol (H2L2) with [MoO2(acac)2] in methanol solutions resulted in the formation of [MoO2(L1)(MeOH)] (1) and [MoO2(L2)(MeOH)] (3), respectively. In contrast, the analogous reactions in acetonitrile afforded the d
The high endwall heat transfer in the junction of the hub and vane/blade is very crucial in turbomachinery and is of great concern for increasing the gas turbine inlet temperature but avoiding hot spots. The vortices generated in that region are mainly responsible for the high heat transfer. By controlling these vortices, heat transfer in the junction region can be controlled. In this study, a new
