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
In the present study, the effect of carbon nanotubes (CNTs) either single walled (SWCNT) or multi walled (MWCNT) on sugar oxidation by Corynascus thermophilus cellobiose dehydrogenase (CtCDH) is investigated. The current observed for the direct electron transfer (DET) communication between the enzyme and the electrode is compared to that of the mediated electron transfer (MET) obtained from CtCDH/
In modern gas turbine, the over tip leakage flow is inevitably generated in the tip gap of the first stage turbine blade due to the freestanding airfoil. In order to obtain a higher thermal efficiency, the turbine inlet temperature is gradually increased. Therefore, the over tip leakage flow induces significant aerodynamic losses and the blade tip and the over tip casing endure high level of therm
A plethora of studies have shown the ability of cereal dietary fiber to improve intestinal health and to protect the colon from diseases. Lowering of blood cholesterol levels and a reduced risk of coronary heart diseases are just examples for beneficial health effects often directly related to β-glucan from cereal grains. β-Glucan is one of the major components of dietary fiber and is found with h
Improving the efficiency of the powertrain system is of great importance to reduce the greenhouse gas CO2. Advanced combustion engine with Partially Premixed Combustion (PPC) is one of the best solutions. It is proved to have a high engine efficiency and low emission level. Using multiple injections is a good way to achieve PPC. The efficiencies using multiple injections were evaluated on a metal
This paper proposes a new test of the null hypothesis of additive fixed effects versus the alternative of general interactive effects. This is not the only test of its kind in the literature; however, it is the only test that is valid in panels where [Formula presented] is fixed. The asymptotic distribution of the new test statistic is derived and simulation results are provided to suggest that it
The influence of carbon dioxide addition to the fuel on soot evolution in ethylene and propane diffusion flames was studied by optical diagnostics. The mole fraction of CO2 addition ranged from 0 to 0.5, while the flow rate of the fuel gas was kept constant for these two sets of flames. Spatial distributions of polycyclic aromatic hydrocarbons (PAHs), temperature, as well as volume fraction, prima
This report presents an integrated biorefinery concept in which wheat straw hydrolysate was treated with co-cultures of osmotolerant thermophilic bacterial strains, Caldicellulosiruptor saccharolyticus and C. owensensis to obtain hydrogen, while the liquid effluent containing acetate and residual glucose was used as feed for polyhydroxybutyrate (PHB) production by Ralstonia eutropha. The Caldicell
