In this work we use low-energy electron microscopy, x-ray photoemission electron microscopy, and x-ray photoelectron spectroscopy to study how the excess Si at the graphene-vacuum interface reorders itself at high temperatures. We show that silicon deposited at room temperature onto multilayer graphene films grown on the SiC(000 (1) over bar) rapidly diffuses to the graphene-SiC interface when hea

OBJECTIVE. Screening examination for retinopathy of prematurity is distressing and painful. The aim of the present study was to investigate whether a Newborn Individualized Developmental Care and Assessment Program intervention during a retinopathy of prematurity examination results in less adverse behavioral, pain, and stress responses as compared with standard care. METHODS. The first 2 eye exam

The measurement of single leptons from the semi-leptonic decay of heavy-flavor hadrons has long been a means for studying heavy-quark production. PHENIX has measured single muons in pp collisions at forward rapidity and single electrons in both pp and AuAu collisions at mid-rapidity at . The most recent PHENIX single lepton results are presented in the context of state-of-the-art pQCD calculations

A review of literature related to fire evacuation in underground transportation systems, e.g., tunnels and subway stations, was carried out with the objectives (1) to identify a theoretical framework that can help understand of human behaviour in the event of a fire in underground transportation systems, (2) to use the theoretical framework to analyse and to identify problems related to fire evacu

The authors tested the hypothesis that experiencing sexual coercion and engaging in sexually coercive behavior are positively associated in a representative sample totaling almost 4,000 Swedish or Norwegian male high school students (estimated response rate 80%). In both surveys, youths who had experienced sexual coercion were approximately three times more likely to engage in sexually coercive be

Nasopharyngeal carcinoma (NPC) is common among southern Chinese including the ethnic Cantonese population living in Hong Kong. Epstein-Barr virus (EBV) infection is detected in all undifferentiated type of NPC in this endemic region. Establishment of stable and latent EBV infection in premalignant nasopharyngeal epithelial cells is an early event in NPC development and may contribute to its pathog

Measurements of electrons from the decay of open-heavy-flavor mesons have shown that the yields are suppressed in Au+Au collisions compared to expectations from binary-scaled p+p collisions. These measurements indicate that charm and bottom quarks interact with the hot dense matter produced in heavy-ion collisions much more than expected. Here we extend these studies to two-particle correlations w

Digital holographic microscopy (DHM) has emerged as a powerful non-invasive tool for cell analysis. It has the capacity to analyse multiple parameters simultaneously, such as cell- number, confluence and phase volume. This is done while cells are still adhered and growing in their culture flask. The aim of this study was to investigate whether DHM was able to monitor drug-induced cell cycle arrest

By simultaneous coherent anti-Stokes Raman scattering (CARS) and 2-photon fluorescence microscopy of Thioflavin-S stained Alzheimer´s diseased human brain tissues, we show evidence of lipid deposits co-localizing with fibrillar β-amyloid (Aβ) plaques. Two lipid morphologies can be observed; lamellar structures and coalescing macro-aggregates of sub-micron sizes to ~25 μm. No significant lipid depo

When fruits ripen, microbial communities start a fierce competition for the freely available fruit sugars. Three yeast lineages, including baker's yeast Saccharomyces cerevisiae, have independently developed the metabolic activity to convert simple sugars into ethanol even under fully aerobic conditions. This fermentation capacity, named Crabtree effect, reduces the cell-biomass production but pro

The production of string rotation and pattern dynamics through the generation of text must build on the presence of a reversible rotary motor which has a synthesizing capacity. This is the discovered AaO-mechanism, which has the power to capture synthesis through emerging AaO-rings. Further, the transcription through the Functional Clause (FC) provides the foundation for their differentiation and

Background: Three genomewide metastudies have recently reported associations with self-reported allergic rhinitis and allergic sensitization. The three studies together identified a set of 37 loci but showed low concordance. This study investigates the reproducibility of the detected single nucleotide polymorphism (SNP) associations in an extensively characterized longitudinal cohort, BAMSE. Metho

This article addresses the understanding of Islam of nine young adult Muslims living in the Malmo and Copenhagen region. 1 Throughout the interviews with the young adults, they mark their distance from what they perceive as unacceptable forms of Islamic ideas and practices, labeling these ideas as extremist and inconsistent. They develop discursive techniques of distancing themselves from the medi

For the first time, we report experimentally and theoretically that nitroaromatic compounds, 2,4-dinitrobenzenethiol and 4-chloro-2-nitrobenzenethiol, on silver sols can be selectively reduced to 2-amino-4-nitrobenzenethiol and 2-amino-4-chlorobenzenethiol simply by irradiating with a visible light in ambient conditions, and the selective photoreduction is a very facile process. The results of qua

There is still controversy as to how body mass index (BMI) affects male reproduction. We investigated how BMI is associated with semen quality and reproductive hormones in 166 men, including 38 severely obese men. Standard semen analysis and sperm DNA integrity analysis were performed, and blood samples were analysed for reproductive hormones. Adjusted for age and time of abstinence, BMI was negat

Popular Abstract in SwedishI avhandlingen undersöks adoptionsberättelser i en svensk kontext. Syftet är tvåfaldigt: För det första, hur adoption beskrivs av vuxna adopterade, för det andra, hur adoption konstrueras i dagspress. Adopterades sätt att skapa mening kring att ”vara adopterad” är i fokus, så är även dessa personliga berättelsers samspel med kulturellt gångbara diskurser på adoptionsområThis dissertation explores adoption stories in a Swedish context. The aim is two-fold: First, how adoption is presented by adopted adults; second, how adoption is constructed in the press. The way adoptees create meaning of “being adopted” is investigated; the way those stories are shaped culturally is also explored. The study was conducted in a qualitative tradition with a constructionist and nar
