Introduction: Despite the high incidence of appendicitis, the diagnosis is often delayed in children. A delayed diagnosis may lead to perforation and formation of an abscess. The treatment of an appendiceal abscess is still a debatable subject and studies have not agreed on what strategy to use. Some prefer immediate operation, whereas others advocate conservative management with or without interv
This text deals with the phenomenon of today’s rune carvers in the Nordic area. By using symbols of antiquity in their craftsmanship, the rune carvers revive an act that is historically significant and bears aspects of identity in the past as well as today. Why do people carve and erect runes stones today? When and where is it done? What are the explicit or implicit purposes? The text tries to ans
Ciliate assemblages play a significant role in the microbial food web. The effects of environmental temperature on assemblage composition may be influenced by abiotic factors such as seasonality and disturbance, but the effects of temperature on ciliate assemblages found on different substrata have not been explored. Sandy bottoms and submerged rocks harbour dissimilar ciliate assemblages, and it

Klass är i ropet igen. I kulturtidskrifter pågår intensiva diskussioner om begreppet. I denna text föreslår jag att vi borde analysera hur klass konstrueras i olika sammanhang för att förstå konstruktionens betydelse för nuet och den historiska utvecklingen.
Increasing precipitation and surface water temperature due to global change may strengthen the salinity gradient in coastal regions, which could influence the behaviour of dinoflagellate migration. We studied diel vertical migration (DVM) behaviour in the dinoflagellates Prorocentrum minimum and Heterocapsa triquetra using vertically stratified laboratory columns with 3 different salinity gradient
The four proton-hole nucleus Pt-204 was populated in the fragmentation of an E/A = 1 GeV Pb-208 beam. The yrast structure of Pt-204 has been observed up to angular momentum I = 10h by detecting delayed gamma-ray transitions originating from metastable states. These long-lived excited states have been identified to have spin-parities of I-pi = (10(+)), (7(-)), and (5(-)) and half-lives of T-1/2 = 1
The central nervous system (CNS) monitors modifications in metabolic parameters or hormone levels and elicits adaptive responses such as food intake regulation. Particularly, within the hypothalamus, leptin modulates the activity of pro-opiomelanocortin (POMC) neurons which are critical regulators of energy balance. Consistent with a pivotal role of the melanocortin system in the control of energy
The article presents and discusses a number of recent scholarly attempts to investigate theological and/or religious dimensions of music. On the basis of critical interpretations of these (Anglophone and German) contributions the article proposes an interdisciplinary approach to a theological aesthetics of music. Such a methodology necessitates any "theologizing" to respect the singular qualities
The transport behavior of lambda-DNA (48 kbp) in fused silica nanoslits is investigated upon application of electrical fields of different strengths. The slit dimensions are 20 nm in height, 3 microm in width, and 500 microm in length. With fields of 30 kV/m or below, the molecules move fluently through the slits, while at higher electrical fields, the DNA molecules move intermittently, resulting
Heparin-induced thrombocytopenia (HIT, type II) is an immune-mediated disorder due to antibodies formed against heparin platelet factor 4 complexes, usually appearing at days 5 to 14 after initiation of heparin. It is important to recognize HIT because heparin prophylaxis or treatment paradoxically associates with new venous and/or arterial thrombosis. Early clinical suspicion and diagnosis togeth
We present results on fabrication and de characterization of vertical InAs nanowire wrap-gate field-effect transistor arrays with a gate length of 50 nm. The wrap gate is defined by evaporation of 50-nm Cr onto a 10-nm-thick HfO2 gate dielectric, where the gate is also separated from the source contact with a 100-nm SiOx spacer layer. For a drain voltage of 0.5 V, we observe a normalized transcond
Abstract in Undetermined We consider expansions of real numbers in non-integer bases. These expansions are generated by beta-shifts. We prove that some sets arising in metric number theory have the countable intersection property. This allows us to consider sets of reals that have common properties in a countable number of different (non-integer) bases. Some of the results are new even for integer
We review the African Monsoon Multidisciplinary Analysis (AMMA) model inter-comparison activities for West Africa. The Model Inter-comparison Project is an evaluation exercise of how global and regional atmospheric models represent seasonal and intra-seasonal variations of the climate and rainfall over the Sahel. The Land surface Model Inter-comparison Project in turn focuses on modelling critical
The behavior of guanidinium chloride at the surface of aqueous solutions is investigated using classical molecular dynamics (MD) simulations. It is found that the population of guanidinium ions oriented parallel to the interface is greater in the surface region than in bulk. The opposite is true for ions in other orientations. Overall, guanidinium chloride is depleted in the surface region, in agr
