sFLASH - Present status and commissioning results

The sFLASH-experiment has been built at the Free-Electron Laser in Hamburg (FLASH) to study the high-gain-FEL amplification of a laser seed from a high harmonic generation (HHG) source. Ideally, the HHG-seed can be amplified up to a GW-power level, improving both the shot-to-shot stability and the longitudinal coherence of the FEL-pulse. In 2010/2011 the sFLASH-components and sub-systems have been

Dowel design of the shear plate dowel joint

The shear plate dowel joint (SPDJ) is a novel connection design for heavy timber structures. The connection uses a single large diameter dowel and glued-on steel plates to transfer loads between members. Consequently, the design of the dowel is of great influence for the global performance of the connection. This paper presents an experimental and numerical investigation of the influence of the ge

Lability classification of soil organic matter in the northern permafrost region

The large stocks of soil organic carbon (SOC) in soils and deposits of the northern permafrost region are sensitive to global warming and permafrost thawing. The potential release of this carbon (C) as greenhouse gases to the atmosphere does not only depend on the total quantity of soil organic matter (SOM) affected by warming and thawing, but it also depends on its lability (i.e., the rate at whi

The Eye of the Common Octopus (Octopus vulgaris)

Octopus vulgaris, well-known from temperate waters of the Mediterranean Sea and a well-cited model species among the cephalopods, has large eyes with which it scans its environment actively and which allow the organism to discriminate objects easily. On cursory examination, the single-chambered eyes of octopus with their spherical lenses resemble vertebrate eyes. However there are also apparent di

They (Don’t) Need Us : Functional Indispensability Impacts Perceptions of Representativeness and Commitment When Lower-Status Groups Go Through an Intergroup Merger

Intergroup changes occur often between subgroups who are asymmetric in status (e.g., size, power, prestige), with important consequences for social identification, especially among the members of lower-status groups. Mergers offer an example of such changes, when subgroups (merger partners) merge into a common, superordinate group (post-merger group). Lower-status subgroups frequently perceive the

The identification, definition and typology of manuscript lacunae

In the article the question of how to identify and define lacunae is discussed, both in general and exemplified in manuscripts containing collections of monastic sayings of the Desert Fathers. These sayings, organized in different ways, were probably written down in Greek during the early fifth century and were soon translated into many languages. In a relational MySQL database, the sayings as the

Incremental validity of ambulatory assessment of acute dynamic risk in predicting time to recidivism among prisoners on parole

This study investigates the incremental validity of changes in ten stress-related acute dynamic risk factors, collected through automated telephony over 30 consecutive days following parole, for predicting time to recidivism during the following year. Before release, the participants completed self-report assessment of some stable risk factors–impulsiveness and history of problematic substance use

Frailty and prediction of recurrent falls over 10 years in a community cohort of 75-year-old women

Background: Frailty captures the age-related declines in health leading to increased vulnerability, including falls which are commonplace in older women. The relationship between frailty and falls is complex, with one leading to the other in a vicious cycle. Aims: This study addresses the gap in understanding how patterns of frailty and falls propensity interact, particularly in those who have not

Spatial relationship between telocytes, interstitial cells of Cajal and the enteric nervous system in the human ileum and colon

Telocytes (TCs) are recently described interstitial cells, present in almost all human organs. Among many other functions, TCs regulate gastrointestinal motility together with the interstitial cells of Cajal (ICCs). TCs and ICCs have close localization in the human myenteric plexus; however, the exact spatial relationship cannot be clearly examined by previously applied double immunofluorescence/c

Field analyses for determination of material parameters - experimental and numerical aspects : Proceedings of the IUTAM Symposium held in Abisko National Park, Kiruna, Sweden, July 31 - August 4, 2000

The need for modelling of materials behaviour under various mechanical conditions is driven by the evolution of computer capacity and the ability of scientists to address complex mechanical problems. Reliable models for materials behaviour, including accurate numerical values of parameters, are necessary for a continued beneficial development of the computational side of solid mechanics. High rate

Experiences of teaching sexual and reproductive health to students with intellectual disabilities

There is growing awareness and international commitment to improving sexual and reproductive health for persons with intellectual disabilities. Despite this, people with intellectual disabilities continue to face stigma and have limited access to sexual health education and information. This qualitative phenomenological study uses data from 10 interviews to describe what it means to teach sexual a

Nordic Gods in Classical Dress : De diis arctois by C. G. Brunius

The 19th century in Sweden, like in many other European countries, saw a largedecline in the quantity of Neo-Latin literary production. However, a range of skillful Latin poets may be named from this period: Johan Lundblad, Johan Tranér, Emil Söderström, Johan Bergman and others, engaged as well in translating from Swedish into Latin as in composing poems of their own. It was also in the 19th cent

Highly-efficient removal of Pb(II), Cu(II) and Cd(II) from water by novel lithium, sodium and potassium titanate reusable microrods

In this work, we report on the efficient removal of heavy metal ions with nanostructured lithium, sodium and potassium titanates from simulated wastewater. The titanates were obtained via a fast, easy and cost effective process based on extraction of sulfate ions from the crystals of titanyl sulfate and their replacement with hydroxyl groups of NaOH, LiOH and KOH solutions leaving the Ti-O framewo

Regulation of carbohydrate metabolism by nitric oxide and hydrogen sulfide : Implications in diabetes

Nitric oxide (NO) and hydrogen sulfide (H2S) are two gasotransmitters that are produced in the human body and have a key role in many of the physiological activities of the various organ systems. Decreased NO bioavailability and deficiency of H2S are involved in the pathophysiology of type 2 diabetes and its complications. Restoration of NO levels have favorable metabolic effects in diabetes. The

Antibiotic-prescribing and antibiotic-resistance patterns among elderly citizens residing in two Nordic regions

Objective: The objective of this study was to compare antibiotic-prescribing rates in 2016 and antibiotic-resistance rates in 2017 among citizens aged ≥85 years between the Capital Region in Denmark and the Skåne Region in Sweden, with regards to overall antibiotic use and antibiotics of choice for urinary tract infections (UTIs) and skin and soft tissue infections (SSTIs). Methods: Inhabitants ≥8
