Since the end of the 1990s, the number of fires increases dramatically in the city of Malmö. Between 1998 and 2009, the increase was 215 percent. A growing number of the fires are intentional and take place outdoors. Most of the fires are also concentrated in a limited number of neighborhoods. Furthermore, many schools are affected. Between 2000 and 2011, nearly 360 intentional fires occurred in s

Ab initio calculations of low-lying electronic states of CrH are presented, including potential energies, dipole and transition dipole moment (TDM) functions, and radiative lifetimes for X (6)Sigma(+), A (6)Sigma(+), 3 (6)Sigma(+), 1 (6)Pi, 2 (6)Pi, 3 (6)Pi, and (6)Delta. Calculation of dynamic correlation effects was performed using the multistate complete active space second-order perturbation m

The dynamic nature of human working memory, the general-purpose system for processing continuous input, while keeping no longer externally available information active in the background, is well captured in immediate free recall of supraspan word-lists. Free recall tasks produce several benchmark memory phenomena, like the U-shaped serial position curve, reflecting enhanced memory for early and la

Objectives: Tetrachloroethylene is the dominant solvent used in dry cleaning worldwide and many workers are potentially exposed. We report here on results of 1296 measurements of tetrachloroethylene undertaken in Nordic dry cleaning shops 1947–2001. Methods: We searched documents and files in the Nordic institutes of occupational health for air measurements of tetrachloroethylene. Repeated measur

Hydrocarbon autoignition has long been an area of intense fundamental chemical interest, and is a key technological process for emerging clean and efficient combustion strategies. Carbon-centered radicals containing an -OOH group, commonly denoted (center dot)QOOH radicals, are produced by isomerization of the alkylperoxy radicals that are formed in the first stages of oxidation. These (center dot

Background: Improving maternal and reproductive health still remains a major challenge in most low-income countries especially in sub-Saharan Africa. The growing inequality in access to maternal health interventions is an issue of great concern. In Ghana, inadequate attention has been given to the inequality gap that exists amongst women when accessing antenatal care during pregnancy and skilled a

Popular Abstract in Swedish Inledning I detta avhandlingsarbete studeras Mycoplasma pneumoniae (MP) och influensa virus ur olika perspektiv. Dessa två smittämnen orsakar båda årliga utbrott med luftvägsinfektioner som ibland blir omfattande epidemier. I båda fallen kan symptomen variera från lätta förkylningsbesvär till mycket svåra, ibland livshotande lunginflammationer. Infektion med MycoplasmaDiagnostic tests based on nucleic acid amplification have become available for Mycoplasma pneumoniae (MP) and influenza viruses. Here, an MP PCR test detected 100% of infections during the first three symptomatic weeks, whereas classical serology detected 21% week 1, 56% week 2, and 100% week 3. Positive PCR results were uncommon in healthy individuals. Levels of MP DNA were significantly higher i

Design importance in product marketing has been dramatically increasing in the last few years. There is hardly a commodity available in the market which could escape the ever-growing design trend. Consumer design awareness is growing simultaneously and thus more and more companies choose to invest into researching possible design applications to their products. Currently where production costs are

The thesis main objective is to establish the determinants for granting executive stock options and to examine their impact on performance for firms listed on OMXS30. The analysis is based on accounting data gathered from annual reports and Thomson Datastream. The empirical results display that firms grant stock options to mitigate the principal-agent problem. Furthermore, risk proves to be positi

One of the overall main purposes for a structural engineer is to design structures and structural elements so that they meet society’s safety requirements, yet use as little material as possible. In order to do so, the designer has to understand and simplify a complex reality. The strut-and-tie method is such a simplification model which allows engineers to design reinforced concrete structures wh

Background and Hypothesis: To clarify, in a large, representative, longitudinal sample, the rate and predictors of diagnostic conversion from Bipolar Disorder (BD) to Schizophrenia (SZ) and from SZ→BD. Design: From individuals born in Sweden 1950–1995 and living there in 1970 or later, we identified at least one initial diagnoses of SZ (n = 8449) and BD (n = 8438) followed for a minimum of 10 and

Victim blaming is a harmful but quite pervasive phenomenon occurring in contemporary societies. When people engage in victim blaming, they shift the burden of the harmful act from the perpetrators and place it upon the victims instead. This article explores how the discourse on moral responsibility can help make sense of victim blaming. The distinction between moral responsibility and blameworthin

Diffusion MRI (dMRI) can probe the tissue microstructure but suffers from low signal-to-noise ratio (SNR) whenever high resolution is combined with high diffusion encoding strengths. Low SNR leads to poor precision as well as poor accuracy of the diffusion-weighted signal; the latter is caused by the rectified noise floor and can be observed as a positive bias in magnitude signal. Super-resolution

Driven by the idea to use alarm data to explore machine learning across Industry 4.0 applications, the goal of this pilot study was to explore how to collect, store, manage and share data from the ESS Control System. Generally, we seek to make any control system data available for research and innovation but started with alarms as a feasible domain in which to explore machine learning. The goals w

Nanowires require surface passivation due to their inherent large surface to volume ratio. We investigate the effect of embedding InP nanowires in different oxides with respect to surface passivation by use of electron beam induced current measurements enabled by a nanoprobe based system inside a scanning electron microscope. The measurements reveal remote doping due to fixed charge carriers in th

Background: Brief episodes of atrial fibrillation (AF) may evolve into longer AF episodes increasing the chances of thrombus formation, stroke, and death. Classical methods for AF detection investigate rhythm irregularity or P-wave absence in the ECG, while deep learning approaches profit from the availability of annotated ECG databases to learn discriminatory features linked to different diagnosi

Spatial distribution information on population density is essential for understanding urban dynamics. In recent decades, remote sensing techniques have often been applied to assess population density, particularly night-time light data (NTL). However, such attempts have resulted in mapped population density at coarse/medium resolution, which often limits the applicability of such data for fine-sca

Using water balance computations, the behavior of different kinds of lakes is discussed. Simple analytical expressions relating water level to hydrological conditions and lake bathymetry are given. The importance of knowing the river basin area when analyzing lake levels is stressed. A conceptual rainfall-runoff model including lake routing is used to simulate runoff and lake levels and to compute
