Popular Abstract in Swedish Kol-kolinteraktioner utgör starka kemiska bindningar. Detta innebär att de är relativt svåra att både bryta och bilda. Föreliggande avhandling sammanfattar mekanistiska studier av två reaktioner, Stillereaktionen och Heckreaktionen, med hjälp av vilka kol-kolbindningar kan bildas. Ett vanligt förekommande sammanfattningsnamn för denna typ av reaktioner är korskopplingsrThe present thesis deals with various types of palladium(II) and platinum(II) complexes and their use in homogeneous catalysis. The focus has been devoted to mechanistic investigations concerning the Stille and Heck reactions and studies under both catalytic and stoichiometric conditions were conducted. As a stoichiometric probe for studying the transmetallation step in the Stille reaction the pl

Public service organizations rely on IT systems to fulfill their missions. IT incidents are more and more frequent and the impacts of IT incidents on the organizations are getting more severe. There is a strong need to manage risks on service related IT systems in public service organizations. Risk management process practiced in software development companies cannot be used in public service orga

Ras homolog gene family member C (RhoC) is a GTPase involved in cell migration, implicated in epithelial-mesenchymal transition and treatment resistance and metastasis of cancer. For example, RhoC has been shown to be involved in resistance to radiation in cervical carcinoma. Here, the effect of X-ray irradiation on RhoC expression in prostate cancer (PCa) xenografts was investigated in both xenog

Objectives: We evaluated the protection afforded by SARS-CoV-2 infection-induced immunity against reinfection among working-age vaccinated individuals during a calendar period from June to December 2022 when Omicron BA.5 was the dominating subvariant in Scania County, Sweden. Methods: The study cohort (n = 71,592) mainly consisted of health care workers. We analyzed 4144 infected cases during the

Cardiovascular comorbidity is common in small cell lung cancer (SCLC) and may significantly affect treatment tolerability and patient outcome. Still, there are no established biomarkers for objective and dynamic assessment as a tool for improved treatment decisions. We have investigated circulating levels of midregional-pro-adrenomedullin (MR-proADM), midregional-proatrial-natriuretic peptide (MR-

The Portable Ice Nucleation Chamber 2 (PINCii) is a newly developed continuous flow diffusion chamber (CFDC) for measuring ice nucleating particles (INPs). PINCii is a vertically oriented parallel-plate CFDC that has been engineered to improve upon the limitations of previous generations of CFDCs. This work presents a detailed description of the PINCii instrument and the upgrades that make it uniq

Health services and medical research are subject to growing use of ADM. Whilst such technology brings many benefits, it is important to understand that it is not just a tool but involves a more fundamental shift in the infrastructure through which healthcare takes place. Where that development is driven by the private sector, it also indicates a wider paradigmatic change in how healthcare is provi

In the adult murine brain, neural stem cells (NSCs) can be found in two main niches: the dentate gyrus (DG) and the subventricular zone (SVZ). In the DG, NSCs produce intermediate progenitors (IPs) that differentiate into excitatory neurons, while progenitors in the SVZ migrate to the olfactory bulb (OB), where they mainly differentiate into inhibitory interneurons. Neurogenesis, the process of ge

Disorder is an intrinsic feature of all solids, from crystals of atoms to superlattices of colloidal nanoparticles. Unlike atomic crystals, in nanocrystal superlattices, a single misplaced particle can affect the positions of neighbors over long distances, leading to cumulative disorder. This elusive form of collective particle displacement leaves clear signatures in diffraction, but little i

BackgroundA specific eHealth device, a surf tablet, was developed for bridging between advanced in-hospital care and children’s homes. Since little is known about determinators for parental eHealth usage, the study’s aim was to explore if parents’ usage of the device was associated with their eHealth literacy, or their satisfaction with their child’s healthcare or with the specific surf tablet.Met

Evidence of air pollution exposure, namely, ambient particulate matter (PM), during pregnancy and an increased risk of autism in children is growing; however, the unique PM sources that contribute to this association are currently unknown. The aim of the present study was to investigate local, source-specific ambient PM exposure during pregnancy and its associations with childhood autism, specific

Meteorologi är ett område som genomgick utveckling under 1900-talet. Det har gått från att vara väldigt erfarenhetsbaserat till att bestå av komplexa matematiska modeller som körs av superdatorer. Ett av de mer nyliga tilläggen är ensembleprognoser. De började användas operativt 1992 av European Centre for Medium-Range Weather Forecasts (ECMWF). En ensembleprognos är uppbyggd av ett flertal modelThis thesis covers the use of ensemble forecasts, how they work and their benefits. It will also give a brief history of weather forecasting followed by an evaluation, where ensemble mean precipitation data from the ECMWF is compared to observation data for 21 different observation stations spread across Sweden. From the evaluation, the mean has difficulty representing amounts of precipitation cor

Modern society is a complex system that combines a lot of variables and one of the most important is electric power supply. Nowadays, our society extremely depends on the secure and consistent electricity supplies, being the main support of current industrial, economical, social and information activity. Furthermore, this dependence is becoming stricter as the society progresses. However, power sy

Förbättringar i reproducerbarhet och kapacitet av akustiska mikrofluidiska infångningssystem Vad är akustisk infångning? Arbetet i den här uppsatsen är fokuserat på mikrofluidiska system som med hjälp av ultraljud kan fånga in celler och små partiklar. Mikrofluidik är ett fält som innefattar tekniker där man hanterar små flöden i mycket små kanaler. Principen för akustisk infångning bygger på attAcoustic trapping is a novel technology that allows for microfluidic sample preparation and pretreatment. The aim of this text is to give the reader a general insight in microfluidics with a focus on acoustic trapping. One of the next steps in the development of acoustic trapping is to promote commercialization of the technology which requires that similar devices can be manufactured reproducibly.

This paper analyzes the effect of overlapping Trade blocs on Trade Facilitation. Using the time, documents and costs incurred as trade facilitation indicators, simulations show interesting yet important effects of an increase in Regional Trade Agreements on trade costs. The results suggest that when it comes to increasing regional trade agreements by 1%, costs are associated with an increase via t

Bluvisions IoT-system har varit huvudfokus under utredningen av om IoT(Internet of Things) är lönsamt att implementera på framtidens Valmetmaskiner. Från början så skulle projektet avgränsas till pressning, kräppning och upprullning men under examensarbetets start fick Valmet svårt att hitta orsaken till varför en ny komponent hade havererat. Havereringen tros ha haft ett samband med höga vibratioBluvision’s IoT-system has been the focus during the investigation if IoT (internet of things) is something that can be implemented on future Valmet machines. From the beginning the bachelor thesis was restricted to press, creping and turn-up. During the initial phase of the bachelor theses start Valmet had problem finding out why a new component had failed. Therefore, it was more valuable for Val
