The present work is devoted to atomic scale structural studies of the surfaces of model heterogeneous catalysts relevant to oxidation reactions. A novel approach using high-energy surface X-ray diffraction combined with mass-spectrometry measurements is employed to perform in situ structural characterization of Pd(100) and Pd(553) single crystal surfaces acting as catalysts in the process of CO ox
Abraham från Godegård – berättelsen om en originell människa och hans musik bygger på Peter Berrys mångåriga efterforskningar om folkskolläraren Abraham Hagholm (1811-1890). Hagholm var son till en fattig torpare i en avlägsen socken av Östergötland och drabbades i tidig ålder av förlamning. Hagholm övervann svårigheterna i sitt liv genom sin starka vilja och sitt livslånga engagemang i musik. Ida
A series of homoleptic bis(tridentate) [Ru-(L)(2)](2+) (1, 3) and heteroleptic [Ru(L)(dqp)](2+) complexes (2, 4) [L = dqxp (1, 2) or dNinp (3, 4); dqxp = 2,6-di(quinoxalin-5-yl)pyridine, dNinp = 2,6-di(N-7-azaindol-1-yl)pyridine, dqp = 2,6-di(quinolin-8-yl)pyridine) was prepared and in the case of 2 and 4 structurally characterized. The presence of dqxp and dNinp in 1-4 result in anodically shifte
Thesis purpose: The purpose is to enhance the understanding of the influence inclusion has on Generation Y consumers when utilised in fashion brands. By isolating two areas of interest namely marginalised gender and size, we aim to provide insight into their effects on the attitude and purchase intention. Methodology: A deductive approach and therefore a quantitative research design is chosen. T
Cell polarity is an ubiquitous and important phenomenon relevant for a plethora of cellular functions. One type of cell polarity is polar growth, where an organism only synthesizes cell envelope at designated locations in the cell. This requires highly organized localization of cellular activities. Understanding the ways in which polarity and polar growth are organized is critical for understandin
Namnl.st-29 175 ORNIS SVECICA 9:175–178, 1999 Flockstorlek och tidspann hos inflygande starar Sturnus vulgaris till övernattningsplatsen Abstract THOMAS KARLSSON & HENRIK LERNER We studied a small communal roost of starlings situated in an urban area. On 14 evenings between 16 June 1993 and 7 July 1994 we recorded 824 flocks with 11,388 individuals. The roost had most starlings per night (more tha

Purpose: This study investigated sleep, television, computer habits, and obesity in school-age children. Design and methods: This was a cross-sectional self-report survey of 1260 children in grade 4 (mean age, 10.1) living in southern Sweden (49.1% boys). The heights and weights of 1097 (87.1%) of the children were recorded. Descriptive statistics, bivariate analyses, and multiple logistic regress
The spontaneous open-field behavioural effects of 10 days of chronic treatment with two clinical doses (10 and 20 mg/kg daily) and one high/toxic dose (100 mg/kg daily) of the selective serotonin reuptake inhibitor citalopram (delivered subcutaneously by implanted osmotic pumps) were examined in rats. Central and peripheral arena locomotor and rearing activities were recorded simultaneously, and t
Certain monoclonal antibodies (mAbs) to type II collagen (CII) induce arthritis in vivo after passive transfer and have adverse effects on chondrocyte cultures and inhibit self assembly of collagen fibrils in vitro. We have examined whether such mAbs have detrimental effects on pre-existing cartilage. Bovine cartilage explants were cultured over 21 days in the presence of two arthritogenic mAbs to
OBJECTIVES: Left ventricular diastolic dysfunction with preserved systolic function (DD-PSF) is associated with an increased risk of morbidity and mortality. Population-based surveys studying the associations between DD-PSF and lifestyle-associated risk factors, such as leisure time physical activity (LTPA) and smoking, are scarce. Thus, the aims were to explore the associations between DD-PSF and
Evolutionary transitions to nocturnality in bees are rare and recent, occurring independently across several families, with activity ranging from crepuscular to strictly nocturnal. Although the “enemy-free” and “competition-free space” hypotheses are often suggested as drivers, these remain little explored in bees. In sympatric diurnal and nocturnal carpenter bees, we show that in addition to temp
Airway epithelium, formed by epithelial cells lining human airways, is a critical barrier against inhaled allergens, viruses, and pollutants. Beyond being a physical barrier, it functions as a first-line defense by secreting alarmins, inflammatory cytokines, and chemokines, thereby activating other immune cells.

This blog post delves into the global phenomenon of the Danish political drama series "Borgen," created by Adam Price. The unexpected revival of "Borgen" for a new season, with significant Netflix financing, marks a pivotal moment in Danish television. This season focuses on geopolitical tensions involving Greenland, offering a fresh perspective on Danish-Greenlandic relations and broader internat
Background: The highest numbers of HIV-infected women are in sub- Saharan Africa, where the natural progression of HIV disease in the absence of treatment results in death before the onset of invasive cervical cancer. With improved access to treatment, several studies outside West Africa demonstrated an increased risk of pre-invasive cervical lesions among HIV-infected women and the positive impac
