The concentrations of ''free'' chloride and hydroxide ions in extracted pore solution from concrete exposed and submerged in a marine field station were studied by the pore solution expression method. In addition, the corresponding concentrations of total acid soluble chloride in the concrete was analyzed. The relationship between total and free chlorides was analyzed and compared with similar dat

We trace the social networks around Chinese entrepreneurs back to their firm's founding to learn about the role early events play in the later success of a business. We use name generator questions paired with career history questions to identify ‘event contacts’ missed by the usual focus on current business. We draw four conclusions from interviews with a large, stratified random sample of entrep

Bakgrund: I Sverige insjuknar årligen ett stort antal personer i stroke. Stroke är den vanligaste sjukdomsorsaken till bestående funktionsnedsättning och medför flest antal vårddagar på sjukhus. Tidig understödd utskrivning från sjukhus till hemmet (Early Supported Discharge) erbjuds enligt de nationella riktlinjerna för vård vid stroke för personer med lindrig till måttlig stroke. Syfte: Att karBackground: In Sweden a large number of people fall ill with stroke every year. Stroke is the most common cause of permanent disability and results in the largest number of hospital days. Early Supported Discharge is offered according to the national guidelines of mild to moderate stroke. Aim: To map how persons with mild to moderate stroke experienced the home environments significance for th

The purpose of the study has been to investigate social workers' experience of working with and supporting women who have been exposed to domestic violence by men during covid-19. We were also interested in how the social workers reasoned about how covid-19 affected this group. The study has a qualitative approach, and eight semi-structured interviews were conducted with social workers at vari

Sveriges vattenledningsnät kräver kontinuerliga och stora in- vesteringar och måste underhållas på ett effektivt sätt; syftet med den här studien var därför att utröna vilka ledningsattribut som är viktigast för att i en ANN-modell identifiera ledningar med hög risk för läckage. Detta gjordes genom att först använda attri- buturvalsmetoderna ReliefF och Recursive Feature Elimination (RFE) tillsammanSweden’s water pipe network demands continuous and large investments and must be maintained in an effective way; the aim with this study was therefore to investigate which pipe features are most important to identify pipes with a high risk of leakage in an ANN-model. This was done by first utilizing the feature selection methods ReliefF and Recursive Feature Elimination (RFE) with Random Forest Clas

Large and mature companies often struggle with their capability of introducing radical innovations, as they can be in conflict with existing business model, processes and bureaucracy. A vital phase of the radical innovation process is the first phase, called the Fuzzy Front End. Scholars claim that FFE activities are entailed with much complexity and uncertainty, yet crucial for a company’s compet

Föreliggande uppsats är ett examensarbete i juris kandidatprogrammet. Uppsatsen är skriven inom området familjerätt men berör även de delar av straffrätten som faller inom ramen för kriminalvårdens betydelse. Jag kommer i uppsatsen klargöra för hur umgängesrätten ser ut för de barn vars föräldrar är frihetsberövade och placerade på en kriminalvårdsanstalt. För att skapa en helhetsbild över barnensThe thesis is written within the field of family law but it also discusses parts of criminal law which carry relevance to correctional treatment. I will clarify how the right of access exists for those children, who’s parents are deprived of liberty and whom are placed in a correctional facility. In order to develop a complete picture of these children’s’ situation I will also explain the Social S

The scientific consensus on climate change is clear, but the social consensus in the United States has yet to concur. Mainstream explanations for the failure of the American public to engage the climate change problem often refer to an information deficit or lacking political will, but have not proven sufficient in accounting for such behavior. A deeper look reveals that the problem lies at the so

Populärvetenskaplig sammanfattning En förändring i det rådande klimatet med en temperaturhöjning på grund av en ökad atmosfärisk CO₂-koncentration kan komma att ha en påverkan på skogar över hela jordgloben. Trädarter som är anpassade till ett visst klimat kan komma att spridas norrut då klimatet kan vara mer passande i framtiden. Detta medför risken att lövträd från central Europa kan konkurrera A climate change will affect the forests around the globe; there may be competitions for available resources that are needed for growth and dispersal. Europe is supposed to be more sensitive and may experience a greater influence than many other regions. As an additional effect of climate change extreme weather events will be more frequent e.g. drought and extreme precipitation that will cause flo

Developing the outlines to a theory of a scene presented in a prior paper, the author´s intention is to further highlight punk´s heterogeneous and dynamic character. Investigating how punk has been transferred to and has developed in Indonesia the author stresses the importance of considering the cultural framework which provides actions with meaning when investigating culture. Based on Clifford G

The issue of possession of the air has been debated over literally thousands of years. The Romans debated the ownership of the air above their cornfields. When man finally could construct aircraft, in this case a balloon, heavier-than-air in the 1780's it did not take long before the first regulation came into force. The issue of state sovereignty had been discussed since the national states s

Access to court is essential for the protection of all rights of individuals. The same holds true for the rights individuals derive from Community law. The Court of Justice of the European Communities (ECJ) is the only court competent to review the legality of acts of the Community institutions. In addition, the ECJ has the last word on the interpretation of Community law. Yet, direct access for i

Today, 14 years have gone since the whole world turned their backs on Rwanda, the small country in East Africa, during a time when its population needed us the most. These were the same nations that already after the Second World War had made a promise about ''Never Again'', then meaning that they would never again allow another attempt to exterminate an entire ethnic group. It was

In the last couple of years it has become more and more common to use control theory in computing systems, for instance operating systems, web servers and databases. The reason for this is to make these systems more robust and stable. This is of interest because we today are more dependent on computing systems in our everyday life, and therefore put higher demands on them. A lot of focus has been

This is the report of a thesis work about controlling an autonomous wheel loader. The objective of the work was to create a complete prototype of an autonomous wheel loader that can operate without any seated driver and without any kind of remote controlling. Another important objective was that this prototype needs to support future development of the autonomous wheel loader. The work was complet

This rapport investigates the transmitter of the Ericsson Bluetooth radio. The open loop modulation scheme of the existing design is theoretically very simple but difficult to implement with available components. Frequency drift of the carrier is a common result of open loop modulation. This work therefore investigates an idea of frequency regulation where the regulation is active during modulatio

In the last few years, the implementation of well-ventilated façades in buildings increased due to their improved energy performance. However, their double-wall construction due to the limited airflow within an air cavity represents a significant fire risk, since the flames that spread into the air cavity can elongate up to ten times. The main goal of this thesis is to provide additional informati

Populärvetenskaplig beskrivning - Är rymden en enda stor tunnelbana? Finns det utomjordiskt liv i universum? Konceptet av Fermi paradoxen har förundrat forskare sedan tidigt 50-tal. Den ställer frågan om varför utomjordiskt liv inte har blivit upptäckt ännu. I jämförelse med andra system i universum är vårt solsystem relativt ungt med sina 4,6 miljarder år. Detta betyder att stjärnor med äldre plAbstract The idea of the spread of life through the galaxy is, in most minds, considered science fiction. Yet, scientists argue that most galaxies have had more than enough time for civilisation development and space travel. In this thesis I simulate how civilisations can spread through the galaxy via close encountering stars, assuming they travel at sub-relativistic speeds. A defined region arou

Short-term tourists visiting formerly residential areas are a potential source of conflict as the short-term tourists change the place they are visiting and represent an inconvenience to residents. This research uses a mixed methods approach with the short-term rent gap framework introduced by Wachsmuth and Weisler (2018) as the quantitative and an additional online expert interview as the qualita

Particle image velocimetry is performed on a model of a high pressure homogenizer, scaled for qualitative similarity of the one phase turbulent flow field in a production scale homogenizer. Flow fields in gap entrance, gap and gap outlet chamber are obtained with high resolution. The measurements show gap flow development and formation of a turbulent wall adherent jet when exiting into the outlet
