A specific class of signaling proteins has been shown to affect adult hematopoiesis in mice, but little is known about the role that these proteins play during hematopoiesis in the fetal liver of the embryo. Here, we have studied and compared the in vitro and in vivo response to a cytokine in bone marrow and fetal liver hematopoietic stem and progenitor cells (HSPCs). We have found that fetal live
This work is an investigation into practical design and loss minimization of DC/DC-switched power supplies, enabling cooler operation, smaller size, and additional or wider areas of use. There is an abundance of switch controller ICs on the market and a few of the manufacturers offer very sophisticated design tools that suggest operating parameters and grade components. However, one of the major
Key words: Innovation, start-ups, exploration, exploitation, formal networks Purpose: The purpose of this thesis is to explore the effects of formal network participation on exploration and exploitation activities in start-ups. Methodology: Following a cross-sectional design, an explorative study was conducted using semi-structured interviews. 18 interviews were performed with representatives fr
Abstract William Gibson’s influential Cyberpunk novel Neuromancer (1984) raises many questions about the effects of rapid technological advancements. The novel presents a Baudrillardian hyperreal situation for the individual characters in the story. Their desires and goals are shaped and directed by the environment in which they live. This essay builds on the work of scholars who have approached G
This thesis assesses the role of social capabilities in the development of Iceland’s economy in 1870-2019. Throughout the period, economic shrinking gradually decreased in the country. The paper argues that a lower frequency of shrinking resulted in better economic performance and that these changes are due to increased resilience to shrinking, provided by the build-up of social capability. By ana
The absence of provisions on hardship under the United Nations Convention for the International Sale of Goods (“CISG”) and the general recognition of the principle of hardship in private international law lead to some problems to maintain the legislative purpose of the Convention as the “lingua franca” of international trade. In order to make the application of the Convention not only on the surfa
The fermented tea beverage kombucha is a traditional drink that has been consumed for thousands of years in Asia. Over the past decades, it has gained greatly in popularity amongst consumers and researchers also in the rest of the world. Kombucha is produced through fermentation of sweetened tea by a complex community of bacteria, mainly dominated by acetic acid bacteria, and a variety of yeast. D
Fractal curves are self similar objects, most of which have the property of being nowhere differentiable. The foundations of fractal curves are in the study of continuous functions with no points of differentiability. In this thesis, the continuity and nowhere differentiability of the Weierstrass function will be proved by using an auxiliary function and mostly elementary tools from Fourier analys
Women’s labour force participation has historically been impeded by their traditional role of taking care of children, a problem that has been reduced with the emergence of formal daycare. However, one problem that remains is that many children in Sweden still do not participate in preschool. Among these children, there is an overrepresentation of foreign-born children and children from low-income
Lake sediments have lately been explored as a 10Be archive, complementing previous research on ice cores and marine sediments. 10Be is an important proxy as it can be used to study past solar activity, a factor which affects the climate. Where other methods studying solar activity only cover a brief period of history, 10Be has the potential to go further back in time. The concentrations of 10Be st
Studiens syfte var att nå en fördjupad förståelse av småbarnsföräldrars användande av interaktiva skärmar när de umgås med sina barn; vilken mening användandet har för individen och vilka följder detta kan få för relationen mellan förälder och barn. Semistrukturerade intervjuer genomfördes med åtta småbarnsföräldrar som sällan, ibland eller ofta använde sig av interaktiva skärmar. Tematisk analys The aim of this study was to gain a greater understanding of the usage of interactive screens by parents of young children, whilst interacting with their children; what role does the usage of interactive screens play for the individual and how does the usage affect the relationship between parent and child. Semi-structured interviews were conducted with eight parents of young children who rarely,
The European Spallation Source ERIC is a new neutron spallation source being built in Lund, Sweden, with NMX as one of the pioneer instruments. NMX is a Quasi-Laue single crystal neutron diffractometer for the investigation of large biological molecules. Wavelength, size and divergence of the neutron beam reaching the sample have to be controlled to properly match the different experimental needs.
The industrial food production system have given rise to tens of thousands of local, national and international social movements concerned with food and agriculture, reacting to the perceived social and environmental failures of the industrial food system. One of the directions inside these movements is the internationally based “local food” movement. The ”local food” movement promotes small-scal
Warming in the Arctic occurs at a much higher rate than the global average, which has a considerable impact on the Arctic terrestrial carbon cycle. Permafrost thawing can release substantial amounts of carbon, whilst tundra shrubification and tree-line advance, on the other hand, may compensate for this. To gain a better understanding of the Arctic carbon cycle in the future, global dynamic vegeta
Purpose: With this paper, the authors aim to explore the dynamic relationship between architectural design and brand identity, particularly emphasizing how McDonald's stores have evolved to reflect the essence of the brand over time. Design/methodology/approach: Historical analysis of McDonald’s restaurant designs and layouts from different sources such as the corporate website, news reports,
