Coprolites (fossilized faeces) are common, yet previously unreported, elements in the Campanian (Upper Cretaceous) shallow-marine strata of Asen, southern Sweden. They are associated with a diverse vertebrate fauna and comprise at least seven different morphotypes that suggest a variety of source animals. Their faecal origin is corroborated by several lines of evidence, including chemical composit

Chronic obstructive pulmonary disease (COPD) is currently the third leading cause of death worldwide and for patients with end-stage disease, the only viable treatment is lung transplantation. In order to meet this clinical need, novel approaches of tissue engineering have emerged. 3D bioprinting technologies are one such rapidly evolving approach and show promising results in terms of biocompatib

Due to the serious problem of greenhouse gas emissions in our atmosphere driving global warming, the need for sustainable initiatives has become an imperative for companies which leads to the necessity of operating sustainably. However, to avoid taking a weak approach to sustainability, it is imperative for companies to carry out a transition involving all three dimensions (environmental, economic

Abstract (1) Carbohydrates are a class of biomolecules that play important roles within the cellular biochemistry. Functionalized carbohydrates are building blocks in our DNA in addition to being major components of the cell’s signaling molecules called proteoglycans and glycosaminoglycans. Certain carbohydrates with aromatic side chains have been shown to inhibit the biosynthesis of these signali

Methods and equipment used for fighting forest fires are different from the ones used in urban fires. Generally, the wildfires are intense, require more resources and tend to spread rapidly. The effectiveness of different suppression techniques is difficult to evaluate since they depend on terrain, weather conditions and other varying factors over time and space. The current study focuses on the s

In this rapid era of technology, speed of communication has become an important factor. To overcome this challenge, 5G/NR technology is being explored. One of the ways of doing this is by using the so called millimeter wave spectrum. In order to make usage of the mmWave spectrum, due to the high path loss it introduces, the beamforming technique is adopted. Beamforming is a method used in high fre

Nanoteknik är ‘big business’. Stora summor pengar står på spel då detta innovativa teknikområde expanderar i snabb takt. Denna undersökning utgår från antagandet att ekonomiska intressen snarare än demokratiska värden och hållbar utveckling styr utvecklingen av nanoteknik i Sverige idag. Detta ses som problematiskt, och det övergripande målet är att föreslå alternativa principer för att styra utveNanotechnology is big business. With rapid innovation and expansion of the field, financial stakes are high. This study is based on the assumption that the development of nanotechnology in Sweden today is controlled by economic interests rather than democratic values and sustainable development. This is considered problematic, and the overall aim with this study is to propose alternative principle

Kombucha, a traditional fermented tea beverage, is gaining popularity for its health benefits due to its bioactive compounds, especially glucuronic acid, known for detoxifying and hepatoprotective properties. Despite its significance, factors influencing glucuronic acid levels are not well understood. This study investigated the impact of initial sugar concentrations (4%, 6%, 8%) and tea types (bl

Hard candy is hygroscopic, implying that hard candy readily absorbs moisture from the environment, resulting in adverse changes in the texture and appearance of the candy. This thesis investigates the impact of different sugar compositions on the moisture absorption of hard candy when exposed to a humid environment. Five different hard candy formulations were exposed to an 8-day storage experiment

SCFA are important end products formed during colonic fermentation of dietary fibre (DF). It has been suggested that propionic and butyric acids affect metabolic parameters, low-grade systemic inflammation, insulin resistance and obesity. The aim of the present study was to investigate whether the various SCFA profiles observed after fermentation in the caecum of rats fed pectin, guar gum and fruc

The island of Isla de los Estados is situated at 54.5 degrees S, 64 degrees W, east of Argentinian Tierra del Fuego, and is located in a sensitive geographic position in relation to the zonal circulation between Antarctica and South America. Its terrestrial records of the last deglaciation, recording atmospheric conditions but within an oceanic setting, can help to clarify changes of regional circ

Recent years have witnessed a rapidly escalating interest on the subject basic income. However, most politicians of Sweden show little interest, some even offense, towards an idea suggesting an income connected to citizenship rather than work. This bachelor thesis aims to define the concept of basic income, and examine how the idea of welfare without demand has emerged as an alternative to dominat

Individualised healthcare is the future of medicine, due to the so called inter-patient variability. The inter-patient variability involves differences in the drug response between different patients. The effect of a drug can usually be divided into pharmacokinetics (PK) and pharmacodynamics (PD). One way to individualise anaesthesia, may be to automate it using closed-loop control systems. This t

More often than not one would encounter a problem, know that the solution has to meet some requirements, but do not how to start or how to progress towards solving it. Motivation for a computer that can solve the problem automatically without explicitly programming it is apparent, i.e. a computer that \programs itself", is greatly desired. The method of genetic programming has demonstrated it

Popular science ArRiyadh, the capital city of the Kingdom of Saudi Arabia is one of the fastest growing cities in the world. During the last decade the population of the city has been increased to five million due to heavy migration towards the city. Due to this population pressure, the living conditions in the different neighborhoods of the city are different. The residents in any city are mainly

Wind actions on roof-mounted solar collectors dier from those on an open range-deployment, due to turbulence and wind stream deection induced by the underlying building. As of December 2010, no construction codes in eect describes the wind loads on such structures, with the exception of the preliminary standard NVN 7250 from the Netherlands, with the latest draft released in 2007. The roofs consid

Presence of lactic acid bacteria on a beer brewery The purpose of this thesis is to help a brewery solve a mayor problem regarding the quality of their product. The brewery has for a considerable amount of time had a problem with the presence of lactic acid bacteria in their product, which has caused it to acid long before the expiration date has passed. The root of the problem could be establishe
