The COVID-19 pandemic has illuminated the lack of knowledge regarding the airborne transmission pathway of disease. The pathway consists of pathogens contained in small particles ejected when speaking and coughing. A crucial characteristic of these particles is their size that is connected to the their suspension longevity in the air as well as the location of generation and deposition within a su
A deeper understanding of the differences between quantum and classical dynamics promises great potential for emerging technologies. Nevertheless, some aspects remain poorly understood, particularly concerning the role of quantum coherence in open quantum systems. On the one hand, coherence leads to entanglement and even nonlocality. On the other, it may lead to a suppression of fluctuations, caus
Under covid-19-pandemin blev många anställda rekommenderade eller tvingade att arbeta på distans (Fackförbundet ST, 2020; Wang m.fl., 2021). Sammantaget arbetade 30–40 procent av arbetstagarna hela eller delar av sin arbetstid på distans under pandemin (Myndigheten för arbetsmiljökunskap, 2021). Den fysiska arbetsplatsen var inte längre en självklarhet; från en dag till en annan blev i stället dis
Dataspelsbranschen beskrivs som både en kulturell näring och som en del av tech-industrin. De olika beskrivningarna ger skilda associationer och illustrerar branschens många sidor. Det är också illustrativt för arbetet som spelutvecklare, vilket ofta beskrivs som en skärningspunkt mellan såväl konstnärligt arbete och teknik, som mellan kultur och kommers. I ett pågående forskningsprojekt om spelut
BACKGROUND/AIM: Opioid overdose deaths have increased in Sweden and other developed countries in recent decades, despite increased treatment efforts and harm-reduction interventions. Further knowledge in this field is needed if this trend is to be reversed. Previous research suggests that mental health and patterns of prescription of opioids and other prescription drugs are associated with increas
Non-negative matrix factorization (NMF) is a relatively new approach to analyze gene expression data that models data by additive combinations of non-negative basis vectors (metagenes). The non-negativity constraint makes sense biologically as genes may either be expressed or not, but never show negative expression. We applied NMF to five different microarray data sets. We estimated the appropriat
Streptococcus pyogenes causes a multitude of local and systemic infections, the most common being pharyngitis in children. Recurrent pharyngeal infections are common and are thought to be due to the re-emergence of intracellular GAS upon completion of antibiotic treatment. The role of colonizing biofilm bacteria in this process is not fully clear. Here, live respiratory epithelial cells were inoc
Samtidigt som bilen är själva grunden för det sätt vi förflyttar oss i samhället, utgör bilismen den främsta orsaken till transportsektorns negativa miljö- och hälsoeffekter. Denna avhandling handlar om politiska försök att gå bortom bilen, mot en mer hållbar form av mobilitet. Hållbar mobilitet eller hållbara transporter, som är den mer använda termen i Sverige, har de senaste decennierna kommit Transport policies in Western Europe are increasingly framed in terms of sustainable mobility. This is a response to an urgent need to tackle adverse consequences of the transport system and implies changes in discourses related to transport. Exploring sustainable mobility is a fruitful way of studying discursive development in a policy field historically connected to priorities radically differen
Alveolar epithelial cells (AEC) have been implicated in pathological remodelling. We examined the capacity of AEC to produce extracellular matrix (ECM) and thereby directly contribute towards remodelling in chronic lung diseases. Cryopreserved type 2 AEC (AEC2) from healthy lungs and chronic obstructive pulmonary disease (COPD) afflicted lungs were cultured in decellularized healthy human lung sli
Nonlinear analysis of structures at high temperatures is studied. Both geometric and material nonlinearities are taken into account.Continuum mechanics relations are used to derive general finite element equations. An alternative formulation to Total Lagrangian (TL) and Updated Lagrangian (UL) formulations named Partially updated Lagrangian (PL) formulation i presented.An isotropic small strain co
In September 2020, the EU Commission published the New Pact on Migration and Asylum in order to offer ‘fresh start’ for EU migration law and policy. Complementary pathways for admission to EU territory were among the proposals set out in the Pact. This article takes stock of the different measures suggested by the Commission to create such complementary pathways. It suggests that the aim of creati
