Vid tiden för Göteborgs 400-årsjubileum var ordet trygghet på många av göteborgarnas läppar. Göteborgs Stad hade sedan några år inlett ett tydligt fokus på att försöka öka invånarnas trygghet genom projekt som ”Trygg i Göteborg” och genom polisiära insatser för att minska den organiserade brottsligheten. Med tanke på sådana insatser tedde det sig kanske inte underligt att hela 15 procent av de sva

The temperature of an atmosphere decreases with increasing altitude, unless a shortwave absorber that causes a temperature inversion exists. Ozone plays this role in the Earth’s atmosphere. In the atmospheres of highly irradiated exoplanets, the shortwave absorbers are predicted to be titanium oxide (TiO) and vanadium oxide (VO). Detections of TiO and VO have been claimed using both low-, and high

In this article the argument is made that a global court like the icc is not suitable for gaining the trust of those it rules over and that the procedure used when trying crimes against humanity is a poor fit as it is to a large extent based on national procedural codes. It is suggested that a split of the icc into several regional bodies with common procedural rules that are amended to suit the s

Background: Anorexia nervosa (AN) is a life-threatening illness. Sometimes long inpatient treatment is necessary, increasing the anxiety that comes with hospitalization and the necessary weight gain. Safe, non-pharmacological adjunctive therapies that improve subjective health are called for. Objective: The aim of this non-randomized, mixed-methods observational study was to describe the utilizati

Climate change is advancing the onset of phenological events, with the rate of advance varying among species and trophic levels. In addition, local populations of the same species may show genetic differences in their response to seasonal cues. If populations of interacting species differ in their response, then climate change may result in geographically varying shifts in the community-level dist

Increasing exports of Fe and DOC from soils, causing browning of freshwaters, have been reported in recent decades in many regions of the northern hemisphere. Afforestation, and in particular an increase of Norway spruce forest in certain regions, is suggested as a driver behind these trends in water chemistry. In this study, we tested the hypothesis that the gradual accumulation of organic soil l

Asymmetric construction of dithiodiketopiperazines on otherwise achiral scaffolds remains a pivotal synthetic challenge encountered in many biologically significant natural products. Herein, we report the first total syntheses of (−)-glionitrin A/B and revise the absolute configurations. Emerging from the study is a novel oxidative sulfenylation of triketopiperazines that enables asymmetric format

In this thesis we study efficient solvers for space-time discontinuous Galerkin spectral element methods (DG-SEM). These discretizations result in fully implicit schemes of variable order in both spatial and temporal directions. The popularity of space-time DG methods has increased in recent years and entropy stable space-time DG-SEM have been constructed for conservation laws, making them interes

The PICT method (pollution-induced community tolerance) can be used to assess whether changes in soil microbial response are due to heavy metal toxicity or not. Microbial community tolerance baseline levels can, however, also change due to variations in soil physicochemical properties. Thirty soil samples (0–20 cm), with geochemical baseline concentrations (GBCs) of heavy metals and from five diff

This article provides an overview of the research on morpho-syntactic challenges in Swedish-speaking children with developmental language disorder (DLD), compared with typically developing (TD) children learning Swedish as their first and second language (L1/L2). Children with DLD show vulnerabilities with verb finiteness, the possessive construction, and noun phrase gender agreement, as well as w

Prevent and manage crises in anesthesiology gives anesthesiologists and allied professionals an overview of the non-technical and technical skills and knowledge that may be required at very short notice, at almost any time of the day.

Context. The unprecedented astrometric precision of the Gaia mission relies on accurate estimates of the locations of sources in the Gaia data stream. This is ultimately performed by point spread function (PSF) fitting, which in turn requires an accurate reconstruction of the PSF, including calibrations of all the major dependences. These include a strong colour dependence due to Gaia's broad G ba

Fix some p∈ [0 , 1] and a positive integer n. The discrete Bak–Sneppen model is a Markov chain on the space of zero-one sequences of length n with periodic boundary conditions. At each moment of time a minimum element (typically, zero) is chosen with equal probability, and it is then replaced alongside both its neighbours by independent Bernoulli(p) random variables. Let ν(n)(p) be the probability

Streamflow plays a major role in the optimal management and allocation of available water resources in each region. Reliable techniques are therefore needed to be developed for streamflow modeling. In the present study, the performance of streamflow modeling is improved via developing novel boosted models. The daily streamflows of four hydrometric stations comprising of the Brantford and Galt stat

Objectives This study aimed to evaluate the image quality of 7 iterative reconstruction (IR) algorithms in comparison to filtered back-projection (FBP) algorithm. Methods An anthropomorphic chest phantom was scanned on 4 computed tomography scanners and reconstructed with FBP and IR algorithms. Image quality of anatomical details - large/medium-sized pulmonary vessels, small pulmonary vessels, tho

Internet-of-things systems are difficult to understand and debug due to their distributed nature and weak connectivity. We address this problem by using relational reference attribute grammars to model and analyze IoT systems with unreachable parts. A transitive device-dependency analysis is given as an example.
