Unsustainability is persistent despite growing awareness that the industrial way of life, its modes of production and consumption need to be transformed. In academic sustainability contexts, however, attention is rarely paid to how industrial societies basically operate and how our everyday life is implicated beyond the usual suspect: consumerism. I argue that it is work, as central social relatio

The modern mobile networks such as the Cloud Radio Network Access (C-RAN) are developing to deal with upcoming requirements in the current generation $4$\textsuperscript{th} Generation (4G) and the upcoming generation i.e. the $5$\textsuperscript{th} Generation (5G). One of the challenges in the modern communication systems is the required high data traffic specially at the fronthaul. Fronthaul in

In the scientific literature and in the media there is a growing concern about toxins in aircraft originating from the air conditioning system as a result from pyrolised jet engine and hydraulic oil, and more recently also de-icing fluid. Many crews have reported long-term neurological and respiratory health effects, but also acute impairment or even incapacitation while performing their flight du

Coreference is a relationship between two or moreexpressions in a text when these expressions referto the same person or thing. Coreference solving,the identification of sets of coreferring mentionsin a text, is a well-studied problem in the fieldof natural language processing (NLP), the com-putational analysis of text. As an example, con-sider this short text:John drove to Judy’s house.He made heIt is said that coreference is difficult to explain, but easy to comprehend; everyoneknows coreference, they just don’t know that they do. We trained a computer toknow it too! Coreference resolution is the identification of phrases that refer to the same entity in a text. Current techniques to solve coreferences use machine-learning algorithms, which require large annotated data sets. Such annota

Studiens syfte är att genom kvalitativa intervjuer i kombination av relevant motivationsforskning och med ett fenomenologiskt angreppsätt förklara och analysera motivation och det idéburna ledarskapet. Empirin är baserad på fyra intervjuer med volontäransvariga inom olika idéburna organisationer. Studiens resultat visar att det finns ett antal faktorer som som är framträdande som motivationskapandThe purpose of this study is to explain and analyze motivation and leadership within non-profit organizations. The study has a qualitative approach, where the empiric is based on five semi-structured interviews, conducted and analyzed using a phenomenlogical approach. The theoretical perspective are based on established theories and research within motivation and the nonprofit sector.

När man skapar ett läkemedel så kan det innehålla både aktiva ämnen och andra hjälpämnen. Hjälpämnena kan bidra till ett läkemedels verkan på flera olika sätt, och en grupp som ofta används är de så kallade cyclodextrinerna. Det finns tre ursprungliga cyclodextriner, alpha beta och gamma, som är ringformade molekyler med olika egenskaper på insidan och utsidan av ringen. På grund av detta så använThe effect of water on α-, β-, and γ-cyclodextrins (CD) was investigated using sorption calorimetry, differential scanning calorimetry and dynamic vapor sorption in order to understand the phase behavior and to create phase diagrams. By relating earlier X-ray diffraction patterns of cyclodextrins equilibrated over saturated salt solutions and literature regarding the cyclodextrin hydrates to the s

We identify the ages that constitute sensitive (or critical) periods in children's development towards their adult health status, skills, and human capital. For this, we use data on families migrating into Sweden from countries that are poorer, with less healthy conditions. Late-life health is proxied by adult height and other adult outcomes. The relation between siblings' ages at migration and th

Benchmarking är en själv-värderingsmetod som gör det möjligt för organisationer att jämföra sig med andra gällande vissa prestanda- och utförandeaspekter. Syftet är att finna goda exempel, sätt att förbättra nuvarande situation samt förstå i vilket tillstånd den egna organisationen befinner sig i vad gäller dessa aspekter. Benchmarking handlar om förändring för kvalitetsutveckling men också om ide

In this work properties of a vacuum phototriode (VPT) and preamplifier unit designed for the electromagnetic calorimeter of the PANDA experiment being built at FAIR are investigated. With the use of lead tungstate and lanthanium bromide scintillators the VPT properties are studied at low photon energies, from tens of key in the lanthanium bromide measurements and between 10 MeV and 60 MeV in the l

In this paper, a penalty function is designed and used in the computation of multitapers which correspond to the Wigner and Choi-Williams distributions. The resulting multitaper spectrogram will approximately fulfill the concentration of the distribution but will additionally suppress the cross-terms outside a predetermined Doppler-lag bandwidth. The specific region as well as the amount of cross-

Changes in x-ray attenuating tissue caused by lung disorders like emphysema or fibrosis are subtle and thus only resolved by high-resolution computed tomography (CT). The structural reorganization, however, is of strong influence for lung function. Dark-field CT (DFCT), based on small-angle scattering of x-rays, reveals such structural changes even at resolutions coarser than the pulmonary network

The use of schemes involving multiple laser pulses to enhance and control the properties of beams of protons accelerated in ultra-intense laser irradiation of planar foil targets is discussed. Specifically, the schemes include the use of a second laser pulse to produce and control preplasma expansion of the target to enhance energy coupling to the proton beam; the use of a second laser pulse to dr

This work demonstrates a new approach - Scheimpflug lidar for atmospheric aerosol monitoring. The atmospheric backscattering echo of a high-power continuous-wave laser diode is received by a Newtonian telescope and recorded by a tilted imaging sensor satisfying the Scheimpflug condition. The principles as well as the lidar equation are discussed in details. A Scheimpflug lidar system operating at

Background: Long-term results after obstetric anal sphincter injury (OASI) are poor. We aimed to improve the long-term outcome after OASI by lessening symptoms of anal incontinence. Methods: In a prospective study at Malmo University Hospital, twenty-six women with at least grade 3B OASI were classified and sutured in a systematic way, including separate suturing of the internal and external sphin
