Natural selection can play an important role in the origin of new species. When reproductive isolation evolves as a result of ecologically-based divergent natural selection, the process is referred to as ecological speciation. In most organisms, sufficient reproductive isolation is considered to be essential for the establishment of new species. However, reproductive isolation typically involves m
In the era of proteomics, glycomics and ultimately metabolomics, with constantly increasing knowledge regarding the human biosystem, the number of specialized therapeutic agents which will be developed against different diseases is predicted to be on the upswing. An increasing portion of these new drugs will, according to recent predictions (Labrou, 2003), be of proteinaceous origin produced accor
Pancreatic cancer represents three percent of all incident cancer cases in developed countries, but stands the 7th most common cause of cancer related death. Worldwide, pancreatic cancer is more common among men, however in Sweden, the incidence ratio between sexes is levelling. Despite extensive research to map underlying risk factors, results are still largely inconclusive. Furthermore, there is
The Ulysses spacecraft has been orbiting the Sun on a highly inclined ellipse (i = 79 degrees, perihelion distance 1.3 AU, aphelion distance 5.4 AU) since it encountered Jupiter in 1992. Between January 2000 and December 2004, the spacecraft completed almost an entire revolution about the Sun, passing through perihelion in May 2001 and aphelion in July 2004. In this five-year period the dust detec
Peeking under the hood of bacteria Imagine you want to figure out what the different parts of your car do and essentially how important they are for it to function properly. The way to answer these questions could be to remove one part at a time and see what happens. In a similar way, whenever scientists want to better understand bacteria, they have learned different ways or techniques of doing s
Hematopoiesis is initiated by a rare population of hematopoietic stem cells (HSC) in the bone marrow (BM). HSCs give rise to red blood cells and white blood cells of myeloid and lymphoid lineages. The red blood cells are responsible for transporting oxygen throughout the body, while the myeloid and lymphoid cells are essentially required for immune responses. The HSCs reside in special niches in t
This thesis focuses on the possibilities to reduce fouling by 1.Modifying the stainless steel surface. For this purpose, surfaces modified with state-of-the-art material science techniques, such as SiF3+ and MoS22+ ion implantation, Diamond-like Carbon (DLC) sputtering, DLC, DLC-Si-O and SiOx Plasma Enhanced Chemical Vapour Deposition (PECVD), autocatalytic Ni-P-PTFE and silica coating, have been
Since 2007, Intelligent Energy (IE) has been involved in developing technologies and services in the hydrogen generation space with E.ON Gas Sverige AB and Swedish Gas Centre. The aim of this work is to support the development of a high-profile demonstration of hydrogen generation technologies in a Swedish context. The overall objective of the demonstration is to deploy a reforming based hydrogen
Popular Abstract in Swedish Avhandlingen innefattar 5 fristående artiklar samt en slutlig sammanfattning av samtliga arbeten. Arbetet behandlar textilproduktion under yngre järnålder framförallt vikingatid. Textilproduktionen har beaktats utifrån de textilredskap som påträffats vid utgrävningar av bosättningar i Skåne, Mälardalsområdet samt Birka, Sverige och Hedeby nuvarande Tyskland. Redskapen oThe initial aim of the present PhD thesis was to develop the method of classification for textile tools to facilitate the study of textile production in an archaeological context. The thesis consists of five separate projects and a concluding summary. The study covers the late Iron Age, mainly the Viking Period. Geographically, the study covers the regions of Scania, in S.W. Sweden, with seven set
Explorations and analysis of soundscapes have, since Canadian R. Murray Schafer's work during the early 1970's, developed into various established research - and artistic disciplines. The interest in sonic environments is today present within a broad range of contemporary art projects and in architectural design. Aesthetics, psychoacoustics, perception, and cognition are all present in this expand
1. In rat isolated hepatic arteries contracted with phenylephrine, acetylcholine and the calcium ionophore A23187 each elicit endothelium-dependent relaxations, which involve both nitric oxide (NO) and endothelium-derived hyperpolarizing factor (EDHF). However, the contribution of prostanoids to these responses, and the potential interaction between EDHF and other endothelium-derived relaxing fact
BACKGROUND: Understanding the patterns of HIV/AIDS epidemics is crucial to tracking and monitoring the progress of prevention and control efforts in countries. We provide a comprehensive assessment of the levels and trends of HIV/AIDS incidence, prevalence, mortality, and coverage of antiretroviral therapy (ART) for 1980-2017 and forecast these estimates to 2030 for 195 countries and territories.M

Studying life history strategies is crucial for understanding the diversity among organisms. The trade-offs in traits related to survival, self-maintenance and reproduction play an important role in the variation of life histories and can be adjusted in response to environmental and physiological factors. Telomeres, which are repetitive DNA sequences found at the ends of chromosomes, can serve as
While scholars have explored how business has increasingly been involved in socio-political issues (Scherer et al., 2016; van der Meer & Jonkman, 2021), less attention has been given to the process of how businesses are held accountable for those issues by stakeholders (Reinecke & Ansari, 2016). Current studies show that multinational corporations are sometimes forced to take a stand on di
Syftet med uppsatsen är att undersöka hur avtalsmekanismen I AvtL påverkas av den ökande digitaliseringen i samhället. Uppsatsen avser även att undersöka hur den ökade användningen av AI, som på vissa sätt har en nära koppling till digitaliseringen, påverkar avtalsmekanismen. AvtL har länge kritiserats för att vara gammal och ineffektiv men på senare år har mer positiva ståndpunkter yttrats. UppsaThe purpose of this study is to investigate the ways that the Swedish Contracts Act on the formation of contracts is affected by the increasing digitalization in our society. The study also aims to investigate how the increased use of AI, which in some ways is closely correlated to digitalization, effects the formation on contracts. The Swedish Contracts Act has long been critiqued for being old a
Den svenska narkotikastrafflagen reglerar tillsammans med andra relevanta lagar, exempelvis smugglingslagen, den straffrättsliga kontrollen av narkotika. NSL har sedan införandet 1968 genomgått ändringar, samtliga i straffskärpande riktning. Idag har Sverige en starkt repressiv och hårt kontrollerande lagstiftning beträffande narkotika jämfört med andra europeiska länder. När nätdroger under 200The Swedish penal law on narcotics (NSL) governs the control of narcotics through criminal law alongside other relevant laws, such as law on penalties for smuggling. NSL has since it came into effect undergone adjustments, all of them in a penalty sharpening direction. Today, Sweden has a repressive and hard-controlling legislation on narcotics in comparison to other European countries. As drugs
Published Data from the European Investment Bank and the Audiovisual Observatory in EU implies that the U.S. made Audiovisuals has dragged down European Audiovisuals' market share in EU market. Apparently, the constant situation is rising up some concerns about the future of the industry and the cultural, social and economical externalities. Considering the double nature of Audiovisuals and th
A need for autonomous electro-mechanical machines performing tasks that can save human efforts and even be deployed in hazardous environments along with the research in the field of human mind and body has led to new fields often called AI Robotics. To provide a mean for stimulating students and researchers around the world for promotion of this new field, an annual world championship, Robocup, ha
