When particles are dispersed in a microfluidic device, its resonant frequencies can be used to manipulate their positions at will. This practice, called acoustophoresis, has been shown to successfully control multiple particles simultaneously with a single vibrating actuator, which is a low-cost and contactless alternative to existing particle manipulation methods, and whose applications include i

We study the effect of childbirth on local and non-local employment dynamics for both men and women using Belgian social security and geo-location data. Applying an event-study design that accounts for treatment effect heterogeneity, we show that 75 percent of the effect of the birth of a first child on the overall gender gap in employment is accounted for by gender disparities in non-local employ

The polytetrafluoroethylene (PTFE) is commonly used to improve the hydrophobic of the gas diffusion layer (GDL). In this study, impacts of PTFE content and piecewise/linear gradient distributions on the transport behavior of liquid water were numerically studied by using a multiphase lattice Boltzmann method. A two-dimensional microstructure of the GDL was reconstructed by stochastic algorithm. Th

Introduction: Several studies have addressed technical aspects of endovascular thrombectomy (EVT), but it is not well known how procedural factors contribute to technical success in routine healthcare. The aim was to explore factors associated with technically successful EVT on nationwide scale. Methods: We did an observational register-based study assessing factors associated with technical succe

Purpose: To study the impact of pregnancy on the serum concentration/dose ratio (C/D-ratio) of topiramate (TPM). Methods: Twelve women with epilepsy using TPM during pregnancy, and 15 pregnancies were studied. The main target variable was the C/D-ratio at baseline and during pregnancy. Additional variables were changes in TPM dose, concomitant use of other antiepileptic drugs, seizure frequency, a

Background: There are two primary phenotypic models of comorbidity between post-traumatic stress disorder (PTSD) and drug use disorder (DUD), i.e. self-medication (PTSD precedes and causes DUD) and susceptibility (DUD precedes and causes PTSD). We sought to clarify the longitudinal relationship between PTSD and DUD, while examining sex differences. Method: We used approximately 23 years of longitu

Microbial carbon use efficiency (CUE) describes the partitioning of carbon (C) between respiration and growth, and this defines the soil-atmosphere C balance. Despite its importance, CUE is not properly represented in soil biogeochemical models. Here, we estimated how CUE varied in soil along a continental gradient. Through a structural equation model, we found that bacterial growth, fungal commun

Many injection drug users are infected with hepatitis C virus (HCV), yet few are treated. With opiate maintenance treatment, expected life length increases, and the incitement increases to treat HCV in order to avoid long term complications. The aim of the present study was to investigate attitudes towards HCV and HCV treatment willingness among opiate-dependent injection drug users at Malmö needl

Background: This study investigates gaze behaviour in child dialogues. In earlier studies the authors have investigated the use of requests for clarification and responses in order to study the co-creation of understanding in a referential communication task. By adding eye tracking, this line of research is now expanded to include non-verbal contributions in conversation. Aims: To investigate

Eftersom människor tillbringar större delen av sin dagliga tid inomhus idag, ökar intresset och användningen av system för inomhusmiljöer, så kallade inomhuspositioneringssystem (IPS). De senaste åren har det därför tillkommit nya dataformat för inomhuskartläggning och kommersiella IPS och har ännu inte studerats ingående. Därför ger rapporten en översikt över huvuddelarna i IPS: dataformat för inAs people spend most of their daily time indoor today, the interest and usage of systems for indoor environments, called indoor positioning systems (IPSs), are increasing. The last couple of years, new data formats for indoor mapping and commercial IPSs have been released and they are not yet extensively studied. Hence, this thesis provides an overview of the main parts of IPSs: data formats for i

Hur vi förvaltar skogen påverkar klimatet Varför skogar är viktiga att undersöka och vad jag undersökte Klimatförändringar påverkar redan såväl mänskliga som naturliga system över hela jordklotet, och de förväntas påverka dessa system även i framtiden. Eftersom skogar absorberar koldioxid från atmosfären och sedan lagrar den i biosfären har de en mildrande effekt på klimatförändringarna. Vad gällBy storing carbon in the biosphere, forests are mitigating climate change. Primary forests have been found to have the potential to store large amounts of carbon, but no studies on carbon storage in Swedish primary forests have been published. This study shows that Swedish primary forests store more carbon in biomass than surrounding secondary forests in the majority of cases and on average. The r

DynahMat is an ongoing project at the Packaging Logistics department at Lund University, which aims to reduce food waste by establishing the true quality and shelf life of chilled goods through a dynamic shelf life prediction (DSLP) service. The idea behind the service is, throughout the entire supply chain, to measure temperature and microbial growth using sensors attached to the package. The inf

When a structure is subjected to an explosion, it will have a response that differs from the one that arises from a static load. Engineers are used to design for static loads but the common knowledge of how to design for explosions is weak. There are guidelines for how to design for explosions with simplified methods but they are partly outdated and the explanation of how they are derived is vague

This paper aims to broaden the discussion on how press freedom can be a powerful tool in the war on corruption. Previous studies have shown a significant relationship between more press freedom and less corruption, it also shows that the causal link runs from press freedom to corruption and not the other way around. There are quite a few studies on the impact of a free press on corruption and ther

The growth of the Internet has made publishing fan-made works based on copyrighted material cheaper and easier, while at the same time making them accessible to a larger audience than ever before. This, in turn, has encouraged more fans to try their hand at writing fan fiction. The copyright holders (or at least some of them), on the other hand, are less than thrilled. However, whether the fans
