Ever since the invention of the internal combustion engine, there has been an interest in optimizing the in-cylinder pressure to achieve reliable and efficient work output. With the use of in-cylinder pressure sensors, piezoelectric injector actuation, the possibility of multiple injection events and the increased availability of computation power, cycle-to-cycle, in-cylinder pressure optimization
Modelica allows systems to be described with reuseable components and with a high precision. To be able to use such complex models efficiently, high demands are set on tools that allow the user to extract the information needed from the models in a straight-forward manner. For this purpose, design-of-experiments techniques can be used to systematically analyze the complex models.In this paper, it
Background: Exposure to airborne particles has a major impact on global health. The probability of these particles to deposit in the respiratory tract during breathing is essential for their toxic effects. Observations have shown that there is a substantial variability in deposition between subjects, not only due to respiratory diseases, but also among individuals with healthy lungs. The factors d
An unbroken digital data flow would save substantial resources in the built environment process. In this study, which is part of a larger Swedish project, data delivery specifications and methods to integrate BIM and geodata are developed and tested with the aim to facilitate such an unbroken data flow. The main focus areas of the study are: (1) specifications that enables building permission appl
Background: Brain metastases are associated with considerable negative effects on patients’ outcome in lung adenocarcinoma (LADC). Here, we investigated the proteomic landscape of primary LADCs and their corresponding brain metastases. Materials and methods: Proteomic profiling was conducted on 20 surgically resected primary and brain metastatic LADC samples via label-free shotgun proteomics. Afte
When individuals self-select (or are selected) into a study based on factors that influence the outcome, conclusions may not generalize to the full population. To compensate for this, results may be adjusted, for example, by standardization on the set of common causes of participation and outcome. Although such standardization is useful in some contexts, the common causes of participation and outc
I denna rapport redovisas populationstrender för 224 svenska fågelarter för olika långa tidsperioder, samt korttidstrender för 12 arter av större däggdjur. Fåglarna har räknats höst, vinter, vår och sommar enligt strikt standardiserade metoder. Sommar- respektive vinterpunktrutter har räknats sedan 1975, i huvudsak i södra Sverige. Standardrutterna räknas också på sommaren (sedan 1996)men täcker hWe present the results of the Swedish Bird Survey, a project run by the Department of Biology, Lund University, as a part of the National Monitoring Programme of the Swedish Environmental Protection Agency. The results for 2022 include data from: 546 winter point counts in 2021/2022 (47th winter), ofwhich 254 were carried out during the Christmas/New Year count, 209 summer point count routes (48th
In studies recruited on a voluntary basis, lack of representativity may impair the ability to generalize findings to the target population. Previous studies, primarily based on surveys, have suggested that generalizability may be improved by exploiting data on individuals who agreed to participate only after receiving one or several reminders, as such individuals may be more similar to non-partici
Sommaren 2018 var ett rekordvarmt år, och en markant ökning på solkurvor konstaterades av Trafikverket. Det finns flera orsaker till varför en solkurva uppstår, förutom den ökade temperaturen. När en solkurva bildas dras slutsatsen i många fall att anledningen endast är hög temperatur och vidare undersökningar utesluts direkt. Detta examensarbete består till stor del av en litteraturstudie som bThe summer of 2018 was a hot year, a significant increase of sun curves was observed by Trafikverket. There are several reasons why a sun curve occurs, in addition to the high temperature. When a sun curve is formed, the conclusion is drawn in many cases that the reason was heat and no further investigations are made. The project consists a literature study that explains the physical theory, fac
Women are born with thousands of ovarian follicles, yet less than 1% will ovulate a mature oocyte. What distinguishes the 99% of follicles destined for demise from the rare 1% that succeed? Here, we leveraged a unique clinical opportunity, paired follicular fluid samples from small antral follicles containing either a viable or an atretic oocyte within the same patients, to uncover the proteomic d
Lunds kommuns klimatpolitiska råd bildades hösten 2018 med uppdrag att utvärdera hur Lunds kommuns samlade politik är förenlig med de klimatmål somantagits av kommunfullmäktige. Rådet, som består av forskare från Lunds universitet (LU) och SLU Alnarp, har sammantaget en bred tvär- och mångvetenskaplig kompetens och en gedigen erfarenhet av samverkan med samhället. Samarbetet mellan Lunds kommun oc
BACKGROUND: Children with autism spectrum disorder (ASD) are at increased risk of epilepsy (EP), but distinguishing epileptic seizures from ASD-associated behavior remains a clinical challenge. Although previous studies have reported changes in peripheral immune markers in adults with EP, it remains unclear whether similar immune signatures are present in pediatric patients with both ASD and EP, a
Traffic-related air pollution has severe implications for our health and stringent emission legislation is being enforced to traffic emissions, for example in the EU, USA, and China. With stricter emission legislation (next is EURO 7) and a rapid growth of battery electrical vehicles (BEVs) the combustion-derived pollutants emitted from the tailpipe are decreasing. However, heavier vehicles have r
Comparison of ROS production of individual particle components from traffic-related sources can inform new health policies and emissions legislation. This work aims to quantify acellular ROS production and oxidative potential (OP) of such individual particle components from combustion, brake, tire, and road wear. Particle characteristics are probed to identify source-specific markers and improve t

Bakgrund Teknikutvecklingen inom hälso- och sjukvårdsområdet möjliggör ständigt nya och mer avancerade sätt att distansmonitorera och vårda patienter digitalt. Digitaliseringen inom hälso- och sjukvårdsområdet i form av till exempel hälsoapplikationer gör det möjligt för patienter och personal att ha kontakt och kommunicera digitalt med varandra (WHO, 2011). itACiH är ett digitalt system där patie
