Exceptionally preserved Mesozoic feathered dinosaur fossils (including birds) are famous, but recognized from only very few localities worldwide, and are especially rare in the Southern Hemisphere. Here we report an assemblage of non-avian and avian dinosaur feathers from an Early Cretaceous polar (around 70°S) environment in what is now southeastern Australia. The recovered remains incorporate sm
The aim of this study was to compare inflammatory response and synovial metaplasia in implant-based immediate breast reconstruction with a biological mesh (Veritas®) with that of a synthetic mesh (TIGR® Matrix Surgical Mesh). We hypothesize that the inflammatory response and formation of synovial metaplasia might be different and the rate of capsular contracture therefore different. The patients w
This study aimed to explore the value of synchrotron-based phase-contrast microcomputed tomography (micro-CT) in pulmonary vascular pathobiology. The microanatomy of the lung is complex with intricate branching patterns. Tissue sections are therefore difficult to interpret. Recruited intrapulmonary bronchopulmonary anastomoses (IBAs) have been described in several forms of pulmonary hypertension,
Background: Orthostatic hypercoagulability is proposed as a mechanism promoting cardiovascular and thromboembolic events after awakening and during prolonged orthostasis. We evaluated early changes in coagulation biomarkers induced by tilt testing among patients investigated for suspected syncope, aiming to test the hypothesis that orthostatic challenge evokes procoagulatory changes to a different
Popular Abstract in Swedish Övergödningen av Östersjön är fortfarande ett problem. Förhöjda krav på kvävereduktion för de svenska avloppsreningsverken är därför att vänta. Detta innebär i sig ökad energi- och kemikalieförbrukning, vilket rimmar illa med ord som energieffektivisering och resurssnålhet. Biologisk kväverening av en specifik delström på reningsverket har dock potential att minska ytbeEnhanced biological nitrogen removal at municipal wastewater treatment plants is a common procedure to prevent eutrophication in water bodies. Increased load, stricter effluent regulations, and demands for reduced resource and energy consumption present new challenges for the wastewater treatment plants. One option when upgrading a wastewater treatment plant is to treat the sludge liquor produced
The EU is accused of having a democratic deficit and one of the reasons for that is the low number of turnouts in democratic elections and referendums. Voter turnout is oneof democracy’s most important indicators of health as it shows to whatextent voters practice their democratic right in a representative democracy. Voter participation is thus an accept of the rules of the representative democrac
The sperm whale (Physeter macrocephalus) is a cosmopolitan species with a broad distribution that ranges from the tropics to the poles. Males are known to migrate between nutrient-rich high latitude waters and low latitude breeding grounds. In the North Atlantic, large males are found up to the southern limits of the ice edge. However, their seasonal distribution patterns remain poorly known in th
This study focuses on the human factors associated with elevator use during evacuation in residential buildings. An online survey is conducted to explore seven factors that may influence people’s choice of elevators in China and the United Kingdom, including floor height, waiting time for elevators, crowd density in front of elevators, mobility limitations, instructions, fire location concerning p
During operation of a nuclear power plant the neutron radiation of the reactor core may induce activity in surrounding components and equipment. These may in turn become radiation hazards during decommissioning or component exchanges. To better plan for this, models of the degree of activation and subsequently, the dose are therefore of great importance. Building upon a previous study of the neutr
During travels, people want to be able to move fast and smooth from point A to point B. Thereby, many people can relate to the struggles which occur when carrying several belongings simultaneously. This master’s thesis was performed in collaboration with Thule Sweden AB and the purpose was to develop a design concept which would make it easier to travel with a wheeled luggage in combination with
Volunteer tourism is an alternative form of tourism that is constantly increasing. The increase can be considered related to trends about social participation, environmental awareness and moral demands. Volunteering in developing countries has previously been associated with altruism and social responsibility, but more recently volunteer organizations have used personal development as part of thei
It is a challenge to make ice cream without any dairy ingredients, since the components in dairy contribute to the unique flavour and structure of the ice cream. The aim with this project was to develop an ice cream mix containing only plant-based ingredients. The source of the main ingredient, the plant-base, was chosen by the company of which this project was requested by. The aim was to develop
While many studies have examined carbon dynamics of boreal ecosystems following wildfire, research on forest-atmosphere carbon fluxes during widespread smoke events from adjacent active wildfires is limited. We examined eddy covariance carbon exchange adjacent to the May 2011 Utikuma Complex wildfire in central Alberta, Canada. Over a one-week period while the wildfire was burning <10 km from the
Objectives: Timely discovery and adequate patient management are crucial in non-small cell lung cancer (NSCLC) since long-term survival is only achievable in early-stage disease. In our study, we aimed to elucidate the effects of time to surgery on survival and to assess the impact of the COVID-19 pandemic on elapsed time until surgery. Methods: In total, 2536 Caucasian NSCLC patients who underwen
The North Sea stands out as one of the most rapidly warming regions of the globe and various types of geographic distribution responses have already been reported, from latitudinal changes to vertical changes. Using catch data from an international bottom trawling monitoring survey, this study investigated how the range size of the North Sea fish assemblage has changed during the last three decade
The DARPA Grand Challenge (DGC) 2005 was a competition, in form of a desert race for autonomous ground vehicles, arranged by the U.S. Defense Advanced Research Project Agency (DARPA). The purpose was to encourage research and development of related technology. The objective of the race was to track a distance of 131.6 miles in less than 10 hours without any human interaction. Only public GPS signa
Sugar beet (Beta vulgaris) is a high value crop, grown mostly in temperate climate and is the source of 30% of the world’s sugar production. There is a high economic incentive to breed for better yielding crops, e.g genetic resistance against diseases. To investigate the effect of new genes in cultivar lines, genetically modified organisms (GMO) can be used but not commercially sold, according to
Plastic pollution is a severe global problem and every year approximately 368 million tons of plastic is produced. Both terrestrial and marine environments are impacted and hundreds of species affected. Marine plastic debris accounts for a weight of 268 940 tons and affects hundreds of marine species through habitat degradation, entanglement and ingestion. Microplastics (MPs) are a type of plastic
