Over the last 7 years, a multidimensional crisis in Venezuela has resulted in massive emigration. Over 7 million have fled the country, with more than 2.4 million seeking to settle in Colombia. Of these, as of 2021, more than 1 million were undocumented, but the situation has started to change with the implementation of an ambitious migrant regularisation scheme. Regularisation promises access to
Do all humans perceive, think and talk about tree cover (‘forests’) in more or less the same way? International forestry programs frequently seem to operate on the assumption that they do. However, recent advances in the language sciences show that languages vary greatly as to how the landscape domain is lexicalized and grammaticalized. Different languages segment and label the large-scale environ
Emplacement of the Central Atlantic Magmatic Province (CAMP) is thought to have triggered global environmental changes and the end-Triassic mass extinction (ETE). However, the mechanisms linking volcanism and environmental change are unclear. Here we provide new insight into these linkages by measuring the abundance of both sedimentary five- to six-ring polycyclic aromatic hydrocarbons (PAHs) and
Emission trading schemes (ETS) have emerged as a popular climate policy measure and are increasingly advocated as policy instruments to support the transition to a green economy. Using complementary analytical methods, this research investigated the institutional developments and complexities of the New Zealand Emissions Trading Scheme (NZ ETS). It focuses on (1) institutional experience and admin
If we admit that, with the exception of language, human perception is predominantly visual, it is reasonable to think that all phenomena conveyed by the visual senses have something in common, but then visual semiotics/visual culture will comprehend much more than painting, sculpture, and architecture. The double coding hypotheses of cognitive psychology, as well as Lessing’s classical opposition
The purpose was to study age related changes in circulatory system via Ballistocardiography (BCG) by utilizing Electromechanical Film (EMFi) sensors by gradually changing the ambient temperature from a thermoneutral area to cold direction. ECG and BCG were recorded from a young person (23 years) and from an older person (78 years), both males. During the tests, brachium blood pressure (BP) and pul
After World War I, millions of men went back from the war front promised of land, work and social justice, but their expectations were unfulfilled by the governments of European countries. In this context, the political landscape was enriched of new ideas, and several new parties, movements and associations born across Europe. In Italy, ANMIG (Disabled Ex-Servicemen National Association) was
Acoustic trapping is becoming increasingly popular as a tool to isolate and enrich biological nanoparticles [1] (particularly extracellular vesicles [2]), yet an inherent problem with acoustic trapping of nanoparticles is calibration of the trapping efficiency. This abstract presents in-house synthesized nanoparticles with different sound scattering properties, either rigid high density gold nanop
Avsikten med detta projekt har varit att utveckla väl fungerande rutiner för PIXE-analys av biologiska prov med anknytning till exponering i arbetsmiljösituationer. Kravet på metoderna är att de tillvaratar PIXE-metodens fördelar (multielementanalys, små prov, snabb analys, låga detektionsgränser) och samtidigt förändrar eller förstör så lite som möjligt av den information som finns i de ursprungl
Popular Abstract in Swedish I de flesta reglerproblem är syftet att hålla utsignalen nära ett önskat värde trots störningar som påverkar systemet. Ibland är det bästa referensvärdet inte känt i förväg. I stället skall det hittas i realtid för att optimera systemets prestanda. Denna avhandling behandlar en så kallade probing-strategi som kan tillämpas för denna klass av problem. Fokus ligger i tillIn most control problems the objective is to control the output at a desired value in spite of disturbances. In some cases, the best setpoint is not known a priori and it should be found online to optimize the process performance. This thesis examines a probing strategy that can be applied for this class of problems. The focus is on the application of the technique to the control of feed supply in
The rapid progress in scanning probe microscopy (SPM) techniques in the last decade has induced an increasing need for manufacturing advanced SPM tips. One important case is conductive and transparent tips. For such tips, only a few techniques have been proposed. which are either expensive or have poor reproducibility. We here propose a simple and cheap sol-gel technique to prepare fibers with a s
Accelerated cell aging, indexed in peripheral leukocytes by telomere shortness and in peripheral blood mononuclear cells (PBMCs) by telomerase activity, has been reported in several studies of major depressive disorder (MDD). However, the relevance of these peripheral measures for brain indices that are presumably more directly related to MDD pathophysiology is unknown. In this study, we explored
Batch processes are becoming more and more important in the chemical process industry, where they are used in the manufacture of specialty materials, which often are highly profitable. Some examples where batch processes are important are the manufacturing of pharmaceuticals, polymers, and semiconductors. The focus of this thesis is exception handling and fault detection in batch control. In the
Lagen (1982:80) om anställningsskydd (LAS) genomgick år 2022 en reform som bland annat innebar en förändring av regleringen för uppsägning på grund av personliga skäl i 7 § LAS. Syftet var att öka förutsebarheten för både arbetsgivare och arbetstagare vid uppsägningar. Med hjälp av rättsdogmatisk metod syftar uppsatsen till att analysera och kartlägga reformen i förhållande till uppsägning på gruThe Employment Protection Act (LAS) underwent a reform in 2022 which, among other things, involved a change in the regulation regarding dismissals on personal grounds in Section 7. The purpose of the reform was to increase predictability for both employers and employees in cases of dismissals. Using a legal dogmatic method, the thesis aims to analyse and map the reform in relation to dismissal on
Recent studies suggest that brain cell type specific intracellular environments may play important roles in the generation of structurally different protein aggregates that define neurodegenerative diseases. Using human induced pluripotent stem cells (hiPSC) and biochemical and vibrational spectroscopy techniques, we studied whether Parkinson’s disease (PD) patient genomes could modulate alpha-syn
