Hej! Så kul att du hittat hit. Jag heter Linn Alenius Wallin och är forskare på Lunds universitet. Jag vill veta mer om barns vänskap med vuxna. Därför undrar jag vad du som är barn och har en vän som är vuxen tycker och tänker om det. Vill du vara med och forska? Du som är förälder, klicka här! Så här går det tillVi ska undersöka barns vänskap med vuxna.Vi träffas i en liten grupp med två andra b

When a child's parents are divorced or separated and violence has occurred between them, several problems can arise in custody cases. The purpose of this thesis is to study these problems and the possibilities to solve them. The first problem I study in this thesis is the different parties' rights which often rise in opposition to one other. These rights refers to the abused parent's r
I dag får en stor del av alla cancerpatienter strålbehandling. Den joniserade strålningen har mycket hög energi och ambitionen är att slå ut hela tumören samtidigt som man skonar den omgivande friska vävnaden i största möjliga mån. Efter bestrålning reparerar cellerna sig till stor del. Eftersom friska celler reparerar sig i högre utsträckning än tumörceller, delar man upp behandlingen i flera beh"Purpose: To find the optimal correction strategy to decrease the set-up errors for pelvic patients at the Department of Radiation Physics at the Finsen Centre, Copenhagen University Hospital. Materials and methods: Using electronic portal imaging devise (EPID), 765 portal images from 17 patients, treated for bladder-, rectum-, anus- or gynecologic-carcinoma were aquired. The patients had th
Under vissa typer av operationer, till exempel då kärlen kring hjärtat opereras, använder sig läkare av en speciell typ av röntgenmaskin för att orientera sig inuti kroppen, så kallad genomlysning. För att undgå att öppna upp bröstkorgen på patienten går läkarna in med små verktyg i kärlen via ljumskarna och upp till hjärtat. Eftersom läkarna står så nära patienten träffar en del av strålningen de"Background: Cataract (opacity of the lens of the eye) has always been thought of as a deterministic effect. That is, that there is a threshold dose below which damage does not occur. However, recent studies suggest a lower threshold and the question whether there is any threshold at all has been raised. One situation that leads to special concern, if this turns out to be the case, is during
Highly oxygenated organic molecules (HOM) play a crucial role in the formation and growth of atmospheric particles, thereby influencing air quality and climate. A comprehensive understanding of HOM formation, particularly an accurate quantification of their yields, is essential to constrain the climate and health impacts of aerosols. Previous studies often reported constant HOM yields as averages,
Radio-based localization in dynamic environments, such as urban and vehicular settings, requires systems that efficiently adapt to varying signal conditions and environmental changes. Factors like multipath interference and obstructions introduce different levels of complexity that affect the accuracy of the localization. Although generalized models offer broad applicability, they often struggle t
Two photoactive iron N-heterocyclic carbene complexes [FeII(btz)2(bpy)]2+ and [FeIII(btz)3]3+, where btz is 3,3’-dimethyl-1,1’-bis(p-tolyl)-4,4’-bis(1,2,3-triazol-5-ylidene) and bpy is 2,2’-bipyridine, have been investigated by Resonant Photoelectron Spectroscopy (RPES). Tuning the incident X-ray photon energy to match core-valence excitations provides a site specific probe of the electronic struc
En slitsmur är en geokonstruktion som utförs genom att paneler platsgjuts med marken som form. Panelerna bildar tillsammans en samverkande vägg. Tekniken är vanlig utomlands men fortfarande relativt ovanlig i Sverige. Behovet, och därmed intresset, av slitsmurar i Sverige växer dock i takt med förtätningen av städer och infrastrukturprojekt som kräver djup schaktning och anläggning. Kraven på låg A diaphragm wall is a retaining wall which is produced as a cast in-situ concrete wall. The ground itself acts as formwork. The technique is widely used internationally but it is comparably still a rare technique in Sweden. However, the need, and therefore interest in Sweden for diaphragm walls is growing as the number of inner city infrastructure projects requiring deep excavations increases. The
Limited partnerships etablerade i Jersey, Guernsey eller England är kom-plexa, avtalskonstruerade fonder. Fonden sådana partnerskap bildar står på kontraktsrättslig grund, ett avtal mellan partnerskapets parter att verka för ett gemensamt ändamål – att förvärva andelar i onoterade bolag i syfte att generera avkastning på insatt kapital.

The fund such partnerships form is based on a contractual basis, an agreement between the parties to the part-nership to operate for a common purpose – to acquire shares in unlisted companies in order to generate a return on the capital invested.

Objectives: This is a protocol for a Cochrane Review (intervention). The objectives are as follows:. To determine the effects of different regimens of systemic opioid analgesics in neonates (term or preterm) undergoing surgery, on mortality, pain and major neurodevelopmental disability. These different regimens may include: different doses of the same opioid; different routes of administration of
Objectives: This is a protocol for a Cochrane Review (intervention). The objectives are as follows:. To determine the effects of systemic opioid analgesics in neonates (term or preterm) undergoing surgery, on mortality, pain and major neurodevelopmental disability, compared to placebo or no drug, non-pharmacological intervention, other opioids, or other analgesics or sedatives.
Hydrogenated vegetable oil (HVO) is a renewable diesel fuel used to replace petroleum diesel. The organic compounds in HVO are poorly characterized; therefore, toxicological properties could be different from petroleum diesel exhaust. The aim of this study was to evaluate the exposure and effective biomarkers in 18 individuals after short-term (3 h) exposure to HVO exhaust and petroleum diesel exh
I slutet av 90-talet utvecklades produkten korslimmat trä, KL-trä. Framtagningen av KL-trä var ett projekt för att framställa ett byggnadsmaterial med avseende att kunna konkurrera med betongindustrin och därigenom bidra till en lägre miljöpåverkan, då trä har en låg påverkan på miljön i förhållande till många andra konstruktionsmaterial. KL-träelement är vanligtvis konstruerade som plattor och haIn the late 1990s cross-laminated timber (CLT) was developed. The development of CLT was a project aimed to produce a structural product that could compete with the concrete industry and contribute to a reduced effect on the environment, due to the low environmental impact of timber in relation to other building materials. CLT elements are usually constructed as panels which contain multiple layer
BACKGROUND: Tremor is a cardinal symptom of Parkinson's disease (PD) that may cause severe disability. As such, objective methods to determine the exact characteristics of the tremor may improve the evaluation of therapy. This methodology study aims to validate the utility of two objective technical methods of recording Parkinsonian tremor and evaluate their ability to determine the effects of Dee
Background Coronavirus disease 2019 (COVID-19) is a rapidly spreading disease that has caused extensive burden to individuals, families, countries, and the world. Effective treatments of COVID-19 are urgently needed.

The global epidemic of Alzheimer disease (AD) is worsening, and no approved treatment can revert or arrest progression of this disease. AD pathology is characterized by the accumulation of amyloid-β (Aβ) plaques and tau neurofibrillary tangles in the brain. Genetic data, as well as autopsy and neuroimaging studies in patients with AD, indicate that Aβ plaque deposition precedes cortical tau pathol
