Aqueous tetrabutylammonium hydroxide, TBAH(aq), has been found to dissolve cellulose and to be a potential solvent for chemical processing or fiber spinning. In this paper, we have investigated the dissolution state of cellulose in 40 wt % TBAH(aq) solvent, and present an extensive study of rheology, combined with static light and small-angle X-ray scattering, to correlate cellulose aggregation wi
The myeloid differentiation primary response gene 88 (MyD88) product is the most common adaptor protein implicated in Toll-like and interleukin receptor (TIR) domain signaling and thus plays an important role in the innate immune system. Despite the fact that the MyD88-dependent pathway has emerged as an important player in cell death processes described in several animal models of neurodegenerati
Microglia, the main phagocytes of the central nervous system (CNS), are involved in the surveillance and maintenance of nervous tissue. During normal tissue homeostasis, microglia migrates within the CNS, phagocytose dead cells and tissue debris, and modulate synapse pruning and spine formation via controlled phagocytosis. In the event of an invasion by a foreign body, microglia are able to phagoc
The longitudinal movement of the arterial wall of large human arteries has shown promise to be an independent indicator of vascular health. Despite growing interest in this movement, its nature, causes, and implications are not fully understood, and existing phantoms have failed to show a pure longitudinal movement that is not secondary to the distension. An often overlooked aspect of the arterial
Integration of non-dispatchable renewable energy sources such as wind and solar into the grid is challenging due to the stochastic nature of energy sources. Hence, electrical hubs (EH) and virtual power plants that combine non-dispatchable energy sources, energy storage and dispatchable energy sources such as internal combustion generators and micro gas turbines are getting popular. However, desig
What happens when people try to remember other, stereotype categorized, individuals based on fluency and familiarity? We examined this issue in our memory test of stereotypes and false memory. 19 males and 21 females participated in our test and the average age was 24.5 years. Each one did at first a few simple "yes-no" judgements for attractive-non attractive faces in combination with p
Many driving schools request cheap, safe alternatives to driving lessons. Some VR (Virtual Reality) car simulators already exist today, but they are either too expensive or not adapted to the Swedish trac system. The purpose of this master thesis has been to investigate whether a virtual environment can be realistic enough for a driving school student to actually benet from using it. To answer the
The rich cultural heritage of China is becoming less relevant and forgotten as a result of rapid urbanization and modern lifestyles. This project aims to preserve the Chinese music heritage by designing an instrument based on the Chinese zither guzheng. Despite the rising interest of traditional instruments, there are factors that are holding people back from practicing them. There have been atte
This examination approaches the field known as fat studies, which by critical problematisation challenges the dominating view of the fat body. Using the discourse analysis What´s the problem represented to be? problem representations regarding body weight, health and weight loss surgery by the association HOBS (Hälsa oberoende av storlek) and the project Feta tankar are compared in relation to a d
This study explores factors associated with the individual's appraisal of anticipated environmental changes caused by energy production facilities. The study took place in a Swedish village where exploratory drilling, that could eventually lead to a uranium mine, was being conducted at the same time as a wind farm was approved. Results from the survey, which included the total population, were int
Tyler, G. 2010: Variability in colour, metallic lustre, and body size of Carabus arvensis Herbst, 1784 (Coleoptera: Carabidae) in relation to habitat properties.-Entomol. Fennica 21: 90-96. Objectives are to elucidate whether populations of Carabus arvensis Herbst, 1784 from contrasting habitats differ in (i) colour, (ii) brightness of metal lustre, or (iii) body size (length of elytra, of elytra
Identifying the relative importance of predation and resources in population dynamics has a long tradition in ecology, while interactions between them have been studied less intensively. In order to disentangle the effects of predation by juvenile fish, algal resource availability and their interactive effects on zooplankton population dynamics, we conducted an enclosure experiment where zooplankt
In the study of insect neuroanatomy, three-dimensional (3D) reconstructions of neurons and neuropils have become a standard technique. As images have to be obtained from whole-mount brain preparations, pigmentation on the brain surface poses a serious challenge to imaging. In insects, this is a major problematic in the first visual neuropil of the optic lobe, the lamina, which is obstructed by the
Inconel 718 is a high strength, heat resistant superalloy that is used extensively for components in hot sections of gas turbine engines. This paper presents an experimental study on the thermal stability of broached Inconel 718 in terms of microstructure and nano-hardness. The broaching process used in this study is similar to that used in gas turbine industries for machining fir-tree root fixing
Overwash is the flow of water and sediment over the crest of a beach system when the runup level of waves or the water level, often enhanced by storm surge, exceeds the local beach or dune crest height. The impacts of overwash on coastal barriers or low lying mainland coasts are striking. Overwash may cause deposition of sand on and landward of the beach crest, large fan shaped deposits on back ba
This contribution presents a novel offline dynamic multi-objective optimization framework for high-pressure liquid chromatographic (HPLC) processes in batch elution mode. The framework allows for optimization of general elution trajectories parametrized with piecewise constant control signals. It is based on a simultaneous method where both the control and state variables are fully discretized in
In the production of solid enzyme products, the granules are dried in a fluidised bed dryer prior to being coated with a protective salt coating. The coating exhibits a low mass diffusivity, which essentially encapsulates any present moisture inside. During the coating process moisture is inevitably added to the granules. It has prior been shown that moisture content in the final product has a neg
Many scholars have studied the rising threat from terrorism and the different challenges for the intelligence community in the prevention of an attack. But little research has been done on countries' different preventive measures within counter-terrorism. One of those examples are between Denmark and Sweden, which have made largely different approaches to preventive measures regarding security
Syfte: Syftet är att identifiera likheter och skillnader för ekonomistyrningssystem mellan olika kulturella regioner. För att uppfylla syftet utformades två delmål: (1) Förklara identifierade skillnader och likheter med kultur som utgångspunkt, (2) Identifiera olika ideer om framtida forskning. Metod: En litteraturstudie genomfördes där sekundärdata från tidigare forskning användes. En metod som Objective: The objective is to identify similarities and differences in management control systems in different cultural regions. To achieve the objective, two strategies have been formulated: (1) Explain identified similarities and differences with culture as a base, (2) Identify different ideas about future research. Methodology: A literature study was conducted in which secondary data from pre
Purpose: The purpose of this thesis is to improve our understanding of strategic thinking by identifying patterns of cognitive elements in individuals perceived to be strong strategic thinkers. Research Questions : in order to fulfill our purpose we formulated two research questions: Research Question 1: What are the common traits and cognitive elements found in the perceived best strategic thinke
