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

Digital twins to personalize medicine

Personalized medicine requires the integration and processing of vast amounts of data. Here, we propose a solution to this challenge that is based on constructing Digital Twins. These are high-resolution models of individual patients that are computationally treated with thousands of drugs to find the drug that is optimal for the patient.

Evaluation of Trends in Optimal Design of Pulse Transformers for Long Pulse High Power Applications

Solid state klystron modulators are typically based on oil-immersed pulse transformers due to their high performance, robustness, simplicity and straightforward design. However, the size of such transformers are highly impacted by pulse power, output voltage, pulse length, and required rise time; key parameters which are difficult to combine in long pulse high power linac applications. In this pap

Tear menisci and corneal subbasal nerve density in patients after laser in situ keratomileusis

Objective: To investigate the relationship between tear menisci and corneal nerve density in patients after laser in situ keratomileusis (LASIK). Methods: Twenty-eight eyes of 14 myopic patients were enrolled. Height and area of the upper and lower tear menisci—upper tear meniscus height, upper tear meniscus area, lower tear meniscus height (LTMH), and lower tear meniscus area (LTMA)—were measured

Glucose-dependent insulinotropic peptide and risk of cardiovascular events and mortality : a prospective study

AIMS/HYPOTHESIS: Evidence that glucose-dependent insulinotropic peptide (GIP) and/or the GIP receptor (GIPR) are involved in cardiovascular biology is emerging. We hypothesised that GIP has untoward effects on cardiovascular biology, in contrast to glucagon-like peptide 1 (GLP-1), and therefore investigated the effects of GIP and GLP-1 concentrations on cardiovascular disease (CVD) and mortality r

The Historical Geography of Phrygia : The Settlement of Leonton Kephalai

This article examines the literary evidence for a settlement in Phrygia named Leonton Kephalai, i.e. Lions´Heads. According to preserved literary sources, of which there are only three, Leonton Kephalai was an important military stronghold from the Achaemenid period until the end of the Roman Republic, but the settlement may have been occupied for longer. Furthermore, one literary source specifial

Stimulation of insulin release by thiols

The effects of thiol compounds on insulin release were studied in microdissected pancreatic islets of non-inbred ob/ob mice. In control experiments the reactivity of thiols against 6,6′-dithiodinicotinic acid and the degradation of mouse insulin were measured. At a concentration of 0.1 mM, 1-thio-D-glucose or reduced glutathione potentiated the insulin-releasing action of 10 mM D-glucose without a

Glucagon and insulin release from the allografted canine pancreas

Six previously pancreatectomized dogs were transplanted with ductligated, pancreatic allografts. Glucagon and insulin levels in the venous outflow from the graft and in the systemic circulation were determined during the first 60 minutes after transplantation. Two of the dogs were subjected to L-arginine stimulation 5 days after transplantation and the glucagon levels in the venous outflow from th

New Guidelines for AOM Treatment in Sweden

In October 2010 new recommendations were issued in Sweden concerningthe treatment of acute otitis media (AOM). Watchful waiting is recommendedfor otherwise healthy children aged 1-12 years with uncomplicated AOM. In allpatients with complicating circumstances and all patients under the age of 1 yearand over the age of 12 years (including adults) antibiotic treatment of AOM isrecommended. In the gu

Positron Emission Tomography and Autoradiography Imaging of P-selectin Activation Using 68Ga-Fucoidan in Photothrombotic Stroke

Background: P-selectin is activated early after stroke, followed by a rapid decline. This time course can be used to generate important information on stroke onset. The latter is crucial for therapeutic decision-making of wake-up strokes (i.e. thrombolysis or not). Here, we evaluated the specific p-selectin inhibitor fucoidan labeled with gallium-68 (68Ga-Fucoidan) as an imaging biomarker for asse

Feminism in Vietnam: Women’s Studies, Gender Research, and Intersections

In this chapter we approach inequalities between women and men in Vietnam through the lens of feminism. We address the manner in which feminism is understood, observing intellectual currents that resonate with global trends in some respects and those reflecting conditions more specific to Vietnam in others. Affinities with global currents, for example, are seen in the ways in which Vietnamese inte

(f)Lex avionica; How soft law serves as an instrumental mediator between professional norms and the hard law regulation of European civil aviation maintenance

The regulation of safety in civil aviation in Europe has become subject to a process of juridification. The role of law in the pro-active perspective of European Aviation Safety Agency (EASA) governance, requires understanding how hard law and soft law interact. The rationality of regulatory systems can be regarded as the normative core from which different normative claims (norms) are deduced dep

Teacher agency and the digital: empowerment or control?

Teachers are both controlling agents and controlled subjects, in any educational system. Educational research has approached this dual role from a variety of practical and theoretical angles, the most notable perhaps being the perspective of teacher autonomy as it is negotiated between, simply speaking, structure and agency. This essay urges to more critically illuminate the relationship between o

Operation of the european FEL at Elettra below 190 nm : A tunable laser source for VUV spectroscopy

Thanks to an intensive technological effort in the framework of the EUFELE collaboration, the European FEL at ELETTRA was able to break the previous record for the shortest wavelength of an FEL oscillator. Novel solutions were adopted for multilayer mirrors to allow FEL operation in the wavelength region between 160 and 190 nm, which is one of the main targets of the project. The characteristics o

Measurement of prompt D0, D+, D*+, and DS+ production in p–Pb collisions at √sNN = 5.02 TeV

The measurement of the production of prompt D0, D+, D*+, and DS+ mesons in proton–lead (p–Pb) collisions at the centre-of-mass energy per nucleon pair of sNN = 5.02 TeV, with an integrated luminosity of 292 ± 11 μb−1, are reported. Differential production cross sections are measured at mid-rapidity (−0.96 < ycms< 0.04) as a function of transverse momentum (pT) in the intervals 0 < pT< 36 GeV/c for
