Al x Ga 1 − x N/GaN high-electron-mobility transistor (HEMT) structures are key components in electronic devices operating at gigahertz or higher frequencies. In order to optimize such HEMT structures, understanding their electronic response at high frequencies and room temperature is required. Here, we present a study of the room temperature free charge carrier properties of the two-dimensional e
Background. Primary nephrogenic diabetes insipidus (NDI) is a rare disorder and little is known about treatment practices and long-term outcome. Methods. Paediatric and adult nephrologists contacted through European professional organizations entered data in an online form. Results. Data were collected on 315 patients (22 countries, male 84%, adults 35%). Mutation testing had been performed in 270
Objective: To evaluate and compare the use of oral glucocorticoids with three classes of bDMARDs in patients with rheumatoid arthritis (RA). Methods: We included patients from 13 observational registries treated with a TNF-inhibitor, abatacept or tocilizumab and with available information on the use of oral glucocorticoids. The main outcome was oral glucocorticoid withdrawal. A McNemar test was us
The full transient dielectric-function (DF) tensor of ZnO after UV-laser excitation in the spectral range 1.4-3.6 eV is obtained by measuring an m-plane-oriented ZnO thin film with femtosecond (fs)-time-resolved spectroscopic ellipsometry. From the merits of the method, we can distinguish between changes in the real and the imaginary part of the DF as well as changes in birefringence and dichroism
This paper examines the role communication strategies play in the maintenance of communication in a classroom. The effect these strategies may have on the acquisition of a language is also discussed. There is often a lack of communication in a Swedish foreign language classroom which leads to the inability to communicate in a native-like way even after several years of learning the language. This
The risk of above-ankle reamputation following a transmetatarsal amputation is around 30%. Patient selection may be crucial to achieve good outcomes, and to avoid futile operations and suffering. We are aware of no previous comparison between the two largest patient groups that undergo lower extremity amputations: patients with diabetes, and patients with non-diabetic peripheral artery disease. Pa
CONTEXT: Although the importance of palliative care (PC) integration in the emergency department (ED) has long been recognized, few formalized programs have been reported, and none have evaluated the experience of ED clinicians with embedded PC.OBJECTIVES: We evaluate the experience of ED clinicians with embedded PC in the ED during the coronavirus disease pandemic.METHODS: ED clinicians completed
Lead-free hybrid metal halide phosphors/crystals showing self-trapped exciton (STE) emission have been recently explored for thermography due to the strong temperature dependence of their photoluminescence (PL) lifetime (τ). However, realizing high-spatial-resolution thermography using polycrystalline powders or crystals presents a challenge. Moreover, the underlying mechanism of temperature-depen
We present data on molluscan fauna within the L3 loess unit (and partially within the S3 paleosol) from the key loess section of Veliki Surduk in Serbia. The section correlates to Marine Isotope Stage (MIS) 8 and late MIS 9 and, thus, spans the time frame from ~350 to 250 ka. The Veliki Surduk loess–paleosol sequence (LPS) is located on the northwestern margin of the Titel loess plateau and compri
Introduction: The scapular osseous free flap (SOFF) is being increasingly used for complex head and neck reconstructions. This study examined the surgical outcomes, focusing on post-operative complications and sequelae in patients who underwent SOFF for maxillary and mandibular reconstructions. Material and Methods: This retrospective, observational, population-based study included patients who un
BACKGROUND: We studied the incidence and risk factors of acute kidney injury (AKI) following coronary angiography (CA) and examined short- and long-term outcomes of patients who developed AKI, including progression of chronic kidney disease (CKD).METHODS: This was a retrospective study of all patients undergoing CA in Iceland from 2008 to 2015, with or without percutaneous coronary intervention. A
2014 is by the Polish government declared as the year of Jan Karski. Fourteen years after his passing, Karski has become an official Polish representative when discussing world politics. One reason is that history politics more and more has become an integrated part of politics and diplomacy. Karski is, as both as a resistance fighter and, first and foremost, as one of the persons who brought atte
BACKGROUND: Cirrhosis represents a state of functional immune paresis with increased infection risk.AIMS: To investigate polymorphonuclear (PMN) leukocyte and monocyte function in ambulatory cirrhotics, and their potential relation with cirrhosis etiology or patient outcome.METHODS: Consecutive ambulatory cirrhotics without current or recent (<1 month) infection or acute decompensation were prospe
The MAX laboratory at Lund University, Sweden, today operates an accelerator system consisting of a 100 MeV racetrack microtron and a 550 MeV storage ring (MAX I). At the moment (July 1994) a new storage ring MAX II is near completion and will start first injections within 2 months. This work gives an overview of the MAX II project including the first beamlines and a description of the accelerator
Arbete i utbyte mot lön utgör grundförutsättningarna för i snart sagt allt ar-bete. Den som bryter denna överenskommelse löper risk att göra sig skyldig till arbetsvägran och i värsta fall bli avskedad. Kort sagt: du bör göra som du blir tillsagd på ditt arbete. I de kollektivavtal som finns mellan Svenska Journalistförbundet och arbets-givarorganisationen Almega finns dock en regel som öppnar upLabour in exchange of salary is the basic agreement of almost all em-ployments. A person who violates this agreement will be at risk of being guilty of refusal of work and, in worst case, could be dismissed. In other words: You should do what you are told at work. However, the collective agreements that exist between the Swedish Journalist Union and the employers organization Almega contains a ru
This thesis investigates the volatility structures found in forward-looking fundamental valuations of the Swedish stock index OMXS30. The evaluated data constitutes daily observations of P/E ratios based on twelve months earnings estimates during the period 2009-01-02 until 2018-10-18. The analysis is conducted by applying a GARCH modelling framework to a log-return transformed return series deriv

Design classics are a well-known phenomenon that includes a large number of objects. In this survey we have focused on furniture and decor design classics. The study was performed by comparing design classics mainly from the 1930s to the
I musikundervisning används rytmikmetoden som en helhetspedagogik för kunskapsinhämtning och för att stärka förståelse för musikteori. I rytmikmetoden är rörelse av kroppen centralt. En grundpelare i rytmikmetoden är praktik före teori eller ”sound before symbol”, alltså att vi behöver uppleva och erfara saker för att sedan kunna lära oss teorin bakom dem. Men hur upplever egentligen eleverna anväIn music education Eurythmics is used as a holistic pedagogy method for acquiring knowledge and to strengthen the understanding of music theory. In the Eurythmics method bodily movement is a central part. One of the main pillars of the method is practice before theory or sound before symbol, meaning that we have to experience things before we can learn the theory behind them. But how do the studen
Denna framställning syftar till att analysera de möjligheter till jämkning av bodelningsresultat som återfinns i den norska danska och svenska rättsordningen. Utgångspunkten i arbetet är Anna Christensens teori om de normativa grundmönstren. Huvudprincipen i samtliga länder är att makarnas giftorättsgods, sedan avdrag för skulder genomförts, delas lika. Med samhällets förändring har undantag till The aim of this thesis is to discuss the possibilities of adjusting unreasonable results when dividing marital property. A comparative study of the relevant legislation in the Swedish Danish and Norwegian legal systems have been conducted. The premise of the discussion is Anna Christensen’s Theory of Normative Patterns. The main principle in all of the compared countries is that the spouses combin
