Popular Abstract in English Bracings are structural components that assure the stability of the load bearing structures is maintained so as a desired level of load-carrying capacity of them is achieved. The present study as a whole involves investigations of either the temporary or permanent bracings that are often required during the construction phase of steel bridges. Current knowledge concerniA number of steel bridges have suffered lateral-torsional failure during their construction due to their lacking adequate lateral and/or rotational stiffness. In most cases, slight bracing can be of great benefit to the main girders involved through their controlling out-of-plane deformations and enabling the resistance that is needed to be achieved. The present research concerned the performance

Popular Abstract in English Popular Science Abstract In our daily routines, we use products and come across applications that involve mixtures of polymers and small amphiphilic molecules in water, for example detergents, pharmaceutics, foodstuffs, shampoos and paints. Polymers are very large molecules formed by smaller units that are repeated and connected. Amphiphilic molecules contain both one pThe research described in this thesis aims to understand the interactions between cationic poly(amidoamine) (PAMAM) dendrimers and small oppositely charged amphiphiles at the solid-liquid and air-liquid interfaces in relation to the bulk solution behavior. There is high interest in PAMAM dendrimers because they are well-defined polymers with a hierarchical architecture which makes them promising m

Popular Abstract in English According to the International Diabetes Federation (IDF), 415 million people suffer from diabetes worldwide. Diabetes occurs when the pancreatic beta cells are no longer able to produce or properly use insulin. Insulin regulates blood glucose levels by enabling glucose uptake into cells, providing the body with energy. Elevated glucose levels cause damages to highly vasDiabetes mellitus is metabolic disorder caused by a defect or lack of beta cell-produced insulin that controls blood glucose homeostasis. In addition to glucose, insulin secretion is regulated by the autonomic nervous system (ANS); the neurotransmitter acetylcholine as well as monoamines, such as dopamine, serotonin, melatonin and norepinephrine. Using a MafA mutant mouse model, we show that MafA

Popular Abstract in English Improving irrigation practices and optimal exploitation of available water resources are vital issues facing water scarcity and similar problems in arid and semiarid countries (e.g., Egypt and Tunisia). In these countries, the use of saline and low quality irrigation water (i.e., brackish irrigation water) is often associated by soil salinization risk and soil degradatiModern irrigation techniques are becoming increasingly important in water-scarce countries especially in arid and semiarid regions. Higher crop production and better water use efficiency are usually achieved by drip irrigation as compared to other irrigation methods. Furthermore, by using drip irrigation simultaneously with brackish irrigation water, some of the water stress due to shortage of fre

Life cycle assessment (LCA) is an established method to assess the various environmental impacts associated with all the stages of a building. The goal of this project was to calculate the environmental releases for a whole office building and investigate the contribution in terms of environmental impact for different parts of the building, as well as the impact from different stages of the life c

The received wisdom has long been that people in Europe reacted with great enthusiasm as war was approaching in August, 1914. However, scholars who have investigated the matter have found little evidence of enthusiasm. There was no unique “spirit of 1914,” and people in general were not happy about the prospect of war. This revisionist thesis is now the new orthodoxy and should as such be subject The received wisdom has long been that people in Europe reacted with great enthusiasm as war was approaching in August, 1914.

How can an online course be designed to promote better mood and improved lighting and darkness conditions in the home? Based on the Information-Motivation-Behaviour Skills Model, the online course comprises multiple components (light, activity and sleep) and various learning strategies. Factual information is provided about, e.g. light as the most potent external time cue for the internal body clo

Svensk tillverkningsindustri bidrar till ca 16 % (Statistics Sweden 2016) av bruttonationalprodukten och medverkar till att ca 900 000 av landets invånare har en anställning (Produktion2030 2016), vilket gör sektorn till en viktig del av Sveriges välfärdssystem. Forskningen syftar främst till att ge industrin verktyg för att analysera och utvärdera produktion för resurseffektivare och lönsammare tIn today’s global market, the industry is struggling every day to make the “correct decisions”. Decisions concerning production can range from smaller improvements to choice tool or equipment investments to relocation of entire production facilities. Increasing globalization leads to both opportunities and challenges, driving the need for fact-based decision-support including costs to be able to e

Our beliefs and opinions are shaped by others, making our social networks crucial in determining what we believe to be true. Sometimes this is for the good because our peers help us form a more accurate opinion. Sometimes it is for the worse because we are led astray. In this context, we address via agent-based computer simulations the extent to which patterns of connectivity within our social net

Bioactive compounds found in plants have been of interest to man since ancient times. These compounds have the ability to modulate the metabolic processes in our bodies, which suggests that they may promote better health. Bioactive compounds vary in their chemical structure, polarity, stability and biological activity. This diversity makes the study of bioactive compounds challenging from the pers

Avhandlingen redovisar en undersökning av samspelet mellan människor i samhällsliv, näringsliv och rättsprocesser, varigenom författaren kartlagt förutsättningarna för enskilda att aktivera civilrättsliga instrument i syfte att främja en utveckling i linje med normer som återspeglas i FNs hållbarhetsmål enligt Agenda 2030.The dissertation is the result of a study of private law viewed as a source This dissertation is the result of a study of private law viewed as a source of power for individuals to enhance values they favour. As an appropriate example of such values, the study has focused on current norms that have been recognized and mirrored as sustainable development goals (SDGs) in the UN Agenda 2030. The research question asks why and under which conditions it is possible for individ

The purchasing strategies in the construction industry have been considered by many writers in construction management as short-term and arms-length. However, a different picture is portrayed in the manufacturing industry, where the purchasing strategies are mostly long-term to secure supply for production. Industrialized building is at the crossroad between construction and manufacturing, which r

The influence of grain boundaries on the mechanical properties of poly-crystalline metals is well known. Here we investigate the influence from a centrally placed grain boundary in nano-sized beams of Cu subjected to tensile loading. The crystallographic orientations in the grains are [100], [110] and [111]. The investigation is performed by means of molecular dynamic simulations employing the mol

With advances in data acquisition and processing methods, spectral inversion of time domain (TD) induced polarization (IP) data is becoming more common. Geological interpretation of inverted spectral parameters, for instance Cole–Cole parameters, often relies on results from systematic laboratory measurements. These are most often carried out with frequency domain (FD) systems on sandstone samplesWith advances in data acquisition and processing methods, spectral inversion of time domain (TD) induced polarization (IP) data is becoming more common.

Online market makers bring together two or more distinct different parties to interact and transact with each other. By doing this, they either reduce search costs, shared transaction costs, or both. Reducing search costs reduces asymmetric information among users and makes sampling of candidates easier. Reducing shared transaction costs means making the transaction more flexible, less costly, and
