Generation of tunable broadband deep ultraviolet radiation from gaseous media using ultrashort laser pulses.

Most modern ultrafast lasers are based on mode-locked fiber or solid-state lasers and operate around the near infrared part of the electromagnetic spectrum. The widely spread CPA based Titanium Sapphire lasers can emit pulses centred around 800nm with durations down to 20 fs. However, for many ultrafast experiments light at different centre frequencies are required. In order to obtain other centre

Interactions between vascular burden and amyloid-β pathology on trajectories of tau accumulation

Cerebrovascular pathology often co-exists with Alzheimer’s disease pathology and can contribute to Alzheimer’s disease-related clinical progression. However, the degree to which vascular burden contributes to Alzheimer’s disease pathological progression is still unclear. This study aimed to investigate interactions between vascular burden and amyloid-β pathology on both baseline tau tangle load an

Combining plasma Aβ and p-tau217 improves detection of brain amyloid in non-demented elderly

Background: Maximizing the efficiency to screen amyloid-positive individuals in asymptomatic and non-demented aged population using blood-based biomarkers is essential for future success of clinical trials in the early stage of Alzheimer’s disease (AD). In this study, we elucidate the utility of combination of plasma amyloid-β (Aβ)-related biomarkers and tau phosphorylated at threonine 217 (p-tau2

Biomarker-Based Prediction of Longitudinal Tau Positron Emission Tomography in Alzheimer Disease

Importance: There is currently no consensus as to which biomarkers best predict longitudinal tau accumulation at different clinical stages of Alzheimer disease (AD). Objective: To describe longitudinal [18F]RO948 tau positron emission tomography (PET) findings across the clinical continuum of AD and determine which biomarker combinations showed the strongest associations with longitudinal tau PET

Konkurrensbegränsning genom selektiva distributionsavtal inom den schweiziska klockindustrin

Sammanfattning Selektiva distributionsavtal används inom många branscher som ett sätt att reglera handeln med produkter och som ett verktyg för att selektera återförsäljarna. Det senaste året har dessa avtal kommit att nyttjas även inom klockbranschen. Det är en speciell bransch där varumärkena får allt större betydelse och det bidrar till en starkare position för de företag som äger och levererar

Persistent organic pollutants, pre-pregnancy use of combined oral contraceptives, age, and time-to-pregnancy in the SELMA cohort

BACKGROUND: We are exposed to several chemicals such as persistent organic pollutants (POPs) in our everyday lives. Prior evidence has suggested that POPs may have adverse effects on reproductive function by disrupting hormone synthesis and metabolism. While there is age-related decline of fertility, the use of hormonal combined oral contraceptives (COCs) and its association to return of fertility

Entomological Lidar : Target Characterization and Field Applications

Sin ringa storlek till trots har insekter enorm inverkan på vårt samhälle och våra liv. Bin, som är centrala för att vårt jordbruk ska fungera, har minskat drastiskt i antal de senaste åren. En utbredd bidöd skulle i bästa fall tvinga oss lägga om vår kosthållning markant, och i värsta fall leda till svält. Utöver detta skulle växter som är beroende av bin för sin fortplantning och djur som äter bThis thesis treats entomological lidar from various angles: laboratory reference work on insects of interest, methodological development of lidar- and data processing methods, as well as field implementations of lidar techniques for entomological research. Insects are crucial components of ecosystems and are currently in a global decline. In this thesis, insects are mainly studied in their roles a

Hyaluronan deposition in islets may precede and direct the location of islet immune-cell infiltrates

AIMS/HYPOTHESIS: Substantial deposition of the extracellular matrix component hyaluronan (HA) is characteristic of insulitis in overt type 1 diabetes. We investigated whether HA accumulation is detectable in islets early in disease pathogenesis and how this affects the development of insulitis and beta cell mass.METHODS: Pancreas tissue from 15 non-diabetic organ donors who were positive for islet

Drivers of increasing iron concentrations in freshwaters

På senare år har flera studier visat på att järnhalten ökar i sjöar och vattendrag i norra Europa. Järn spelar en nyckelroll i akvatiska miljöer genom att påverka tillgängligheten av andra näringsämnen i vattnet så som kväve och fosfor, vilket kan reglera tillväxten av växtplankton. Dessutom färgar järn tillsammans med organiskt material vatten brunt. När vattnet blir brunare försämras ljusklimate

Mirror, mirror on the wall, who's the innovator after all? : An explorative study of a management-initiated employee innovation process

Today, the innovation arena is open to a wider range of participants than previously acknowledged. One specifically neglected group of innovators in traditional innovation studies is non-R&D and non-managerial employees, also referred to as ‘ordinary’ employees by the existing body of literature on employee-driven innovation (EDI). These employees have no formal innovation function, meaning th

Peer Assisted Study Sessions (SI-PASS) in Higher Education, a European overview

The paper/presentation gives an overview of Peer-Assisted Study Schemes (SI-PASS) in Higher Education in Europe. SI-PASS is a method of improving student performance in “difficult” courses combining “how to learn” with “what to learn”. SI-PASS sessions are scheduled parallel to the regular education and are guided and facilitated by a “senior” student, the SI-PASS leader. The sessions are based on

Frame dynamics and stakeholders in risk governance

The EU governance of food safety and GM food and feed has gone through significant changes since the BSE crisis and food scares during the 1990s. This work focuses on one particular new feature; the role of stakeholders representing the food chain: biotech associations, farmer organizations, food and feed processors, consumer organizations and environmental NGOs. These stakeholders are not merely

Elucidating causal relationships between energy homeostasis and cardiometabolic outcomes

Energy metabolism dyshomeostasis is associated with multiple health problems. For example, abundant epidemiological data show that obesity and overweight increase the risk of cardiometabolic diseases and early mortality. Type 2 diabetes (T2D), characterized by chronically elevated blood glucose, is also associated with debilitating complications, high healthcare costs and mortality, with cardiovas
