A load frame for in situ mechanical testing is developed for the microtomography end stations at the imaging beamline P05 and the high-energy material science beamline P07 of PETRA III at DESY, both operated by the Helmholtz- Zentrum Geesthacht. The load frame is fully integrated into the beamline control system and can be controlled via a feedback loop. All relevant parameters (load, displacement

Phthalates are used as plasticizers in polyvinyl chloride (PVC) materials and it is known that phthalates may migrate into the surrounding environment and then become a source for human uptake. The aim of the study was to investigate whether residential PVC flooring was related to the urinary levels of phthalate metabolites determined in pregnant women. The data were from the Swedish SELMA study w

We develop an agent-based model in which heterogeneous and boundedly rational agents interact by trading a risky asset at an endogenously set price. Agents are endowed with balance sheets comprising the risky asset as well as cash on the asset side and equity capital as well as debt on the liabilities side. A number of findings emerge when simulating the model: we find that the empirically observa

(S)-Hydroxynitrile lyases from Hevea brasiliensis, Manihot esculenta, and Sorghum bicolor and (R)-hydroxynitrile lyase from Prunus amygdalus have been used as biocatalyst for the enantiospecific addition of hydrogen cyanide to aldehydes in organic solvents. The effects of the reaction parameters on the enzymatic reaction rate and product enantiomeric excess (e.e.) are presented. The reaction rate

Background: It has been shown that the socio-geographical environment of residential areas, such as altitude, affects the health status and health-maintenance behavior of residents. Here, we examined a hypothesis that altitude of residence would influence glycemic control in a general elderly population living in a rural area. Methods: A thousand and sixteen participants living in a mountainous re

In this paper we analyze the effects of body shadowing in multiple-input-multiple-output (MIMO) channels used for personal area networks (PANs). We give physical reasoning to why PANs may experience two different types of shadowing, and to support our argument, we present results from a measurement campaign for three different PAN channels with human influence. The campaign is performed using diff

We have previously shown that expression of CD40 has a favorable prognostic impact in diffuse large B-cell lymphoma (DLBCL) after anthracycline-based chemotherapy. Here we examined the prognostic value of immunohistochemically defined CD40 expression in 95 patients with DLBCL treated with both anthracycline-based chemotherapy and rituximab. Using a 10% cut-off level, 77% of the patients had CD40-p

Archaeology’s turn to digital documentation poses questions for the long-term preservation of archaeological data and their future re-use—questions that have relevance also for the debates about open science and data archivization in the natural and social sciences. In this paper, I investigate how the nexus of epistemology and digital materialities affect attempts to open up archaeological data f

The aim of this study was to examine health care social workers’ and psychologists' perception of counseling (stödsamtal), how jurisdictional work can be seen within counseling and what significance the jurisdictional work has for the health care social worker’s professional identity. The method chosen was semi-structured interviews with four health care social workers and four psychologists,

IKEA is today using HP’s application lifecycle testing environment which consists of several tools. One of the tools is Performance Center which is used to schedule and run performance tests. When a test run is finished, the tester uses LoadRunner Analysis which is another tool in HP’s testing environment. This tool is used to visualize a test run in graphs. These graphs are used by the tester to

In recent years a lot of criticism against the main assumptions of economic modeling has come to up, this has led to physicists entering the field of economics. By applying models originally developed for physics to economics, especially finance, analyzing methods with a different approach can be used. Inspired by earthquakes Didier Sornette created a model that analyze financial market crashes. W

A study on the online process of producing idioms in writing and how second language learners manage the production and comprehension of idioms may provide a useful and comprehensive investigation of the production, comprehension and acquisition of language. The study in this paper investigated how Swedish (L1) second language learners of English (L2) produce and comprehend written idioms in the L

Jet substructure observables have significantly extended the search program for physics beyond the standard model at the Large Hadron Collider. The state-of-the-art tools have been motivated by theoretical calculations, but there has never been a direct comparison between data and calculations of jet substructure observables that are accurate beyond leading-logarithm approximation. Such observable
