High-energy surface X-ray diffraction for fast surface structure determination.

Understanding the interaction between surfaces and their surroundings is crucial in many materials-science fields, such as catalysis, corrosion, and thin-film electronics, but existing characterization methods have not been capable of fully determining the structure of surfaces during dynamic processes, such as catalytic reactions, in a reasonable time frame. We demonstrate an x-ray-diffraction-ba

Look Here, Eye Movements Play a Functional Role in Memory Retrieval.

Research on episodic memory has established that spontaneous eye movements occur to spaces associated with retrieved information even if those spaces are blank at the time of retrieval. Although it has been claimed that such looks to "nothing" can function as facilitatory retrieval cues, there is currently no conclusive evidence for such an effect. In the present study, we addressed this fundament

When Is the Deep Inferior Epigastric Artery Flap Indicated for Breast Reconstruction in Patients not Treated With Radiotherapy?

BACKGROUND: It is controversial whether breast reconstruction with a microvascular free flap should be done without restrictions in patients who have not had radiotherapy. Many regard it as too expensive, but some consider it better and more economically advantageous than an implant reconstruction. METHODS: Databases of publications were searched to find out under what conditions is it suitable to

Evaluating the Effect of Biofilm Thickness on Nitrification in Moving Bed Biofilm Reactors.

This study evaluates the effect of biofilm thickness on the nitrifying activity in moving bed biofilm reactors (MBBRs) in a controlled environment. In-depth understanding of biofilm properties in MBBRs and their effect on the overall treatment efficiency compose the key to optimizing process stability and efficiency. However, evaluating biofilm properties in continuously operated MBBRs can be extr

Interdisciplinary research and geography: Overcoming barriers through proximity

Contributions on interdisciplinary research have so far focused on barriers to such collaborations and strategies for overcoming these. In this paper, we propose that a geographical perspective contributes to understand the formation of successful interdisciplinary research collaborations. The empirical analysis of a centre for clinical cancer research illustrates the importance of considering the

Grasping the dynamics of suicidal behaviour: combining time-geographic life charting and COPE ratings.

The aim of this study is to explore whether a time-geographic life charting, combined with a survey of a person's coping capacities over time, elucidates the pathway to suicidal behaviour, and therefore could be useful in suicide prevention. Twenty-three patients were recruited shortly after a suicide attempt. A time-geographic life charting and COPE inventory ratings were used separately and in c

Homoleptic Iron(II) Complexes with the Ionogenic Ligand 6,6'-Bis(1H-tetrazol-5-yl)-2,2'-bipyridine: Spin Crossover Behavior in a Singular 2D Spin Crossover Coordination Polymer.

Deprotonation of the ionogenic tetradentate ligand 6,6'-bis(1H-tetrazol-5-yl)-2,2'-bipyridine [H2bipy(ttr)2] in the presence of Fe(II) in solution has afforded an anionic mononuclear complex and a neutral two-dimensional coordination polymer formulated as, respectively, NEt3H{Fe[bipy(ttr)2][Hbipy(ttr)2]}·3MeOH (1) and {Fe[bipy(ttr)2]}n (2). The anions [Hbipy(ttr)2](-) and [bipy(ttr)2](2-) embrace

Systematic Review of the Benefits of Physical Therapy Within a Multidisciplinary Care Approach for People With Schizophrenia

Background. Although schizophrenia is the fifth leading cause of disability-adjusted life years worldwide in people aged 15 to 44 years, the clinical evidence of physical therapy as a complementary treatment remains largely unknown. Purpose. The purpose of this study was to systematically review randomized controlled trials (RCTs) evaluating the effectiveness of physical therapy for people with sc

Stretch-dependent smooth muscledifferentiation in theportal vein - role of actin polymerization, calcium signaling and microRNAs.

The mechanical forces acting onsmooth muscle cells in the vascular wall are known to regulate processes such as vascular remodeling and contractile differentiation. However, investigations to elucidate the underlying mechanisms of mechanotransduction in smooth muscle have been hampered by technical limitations associated with mechanical studies on pressurized small arteries, due primarily to the s

Combined molecular and morphological phylogeny of Eulophidae (Hymenoptera: Chalcidoidea), with focus on the subfamily Entedoninae

A new combined molecular and morphological phylogeny of the Eulophidae is presented with special reference to the subfamily Entedoninae. We examined 28S D2D5 and CO1 gene regions with parsimony and partitioned Bayesian analyses, and examined the impact of a small set of historically recognized morphological characters on combined analyses. Eulophidae was strongly supported as monophyletic only aft

Transforming growth factor (TGF)-β levels and unprovoked recurrent venous thromboembolism.

Prediction of recurrence in patients with unprovoked venous thromboembolism (VTE) remains a challenge. Studies of atherosclerosis suggest a protective role of transforming growth factor (TGF)-β. However, the role of TGF-β has not been studied in VTE. The aim of this study was to investigate TGF-β as a predictive marker of recurrent VTE in patients with a first episode of unprovoked VTE. Patients i

Tröger's Base Twisted Amides: Endo Functionalization and Synthesis of an Inverted Crown Ether

Taking advantage of the unconventional reactivity of twisted mono- and bis-amides of Tröger's base (TB), rac-6 and rac-7, respectively, the first synthesis of a 6-endo-monosubstituted TB analogue, rac-9, and the first rational synthesis of a 6,12-endo,endo-disubstituted TB analogue, rac-11, have been achieved. The bis-TB crown ether, meso-13, was prepared starting from rac-7. Meso-13 constitutes a

Forward-backward multiplicity correlations in pp collisions at root s=0.9, 2.76 and 7 TeV

The strength of forward-backward (FB) multiplicity correlations is measured by the ALICE detector in proton-proton (pp) collisions at = 0.9, 2.76 and 7 TeV. The measurement is performed in the central pseudorapidity region (|eta| < 0.8) for the transverse momentum p (T) > 0.3 GeV/c. Two separate pseudorapidity windows of width (delta eta) ranging from 0.2 to 0.8 are chosen symmetrically around eta

Do risk factors for schizophrenia predispose to emigration?

Objective: Increased incidence rates of schizophrenia in immigrants still lack a satisfactory explanation. The aim of this study was to examine the hypothesis that risk factors for schizophrenia also increase the risk of emigration to a foreign country. If valid, Danes emigrating from Denmark carry a higher predisposition to develop schizophrenia compared to Danes living in Denmark. Methods: Utili

The social world within reach: Intersubjective manifestations of action completion.

This is a study of the intersubjective recognizability of the “proper” accomplishment of children’s actions, and in particular of how the status of actions as properly completed is often actively made recognizable through speech and various modulations of bodily movement. In addition to analyzing how children do this in a number of cases, it is also argued that these manifestations of action compl

Early vascular ageing in translation: from laboratory investigations to clinical applications in cardiovascular prevention.

The ageing of the vascular tree is a fundamental reflection of biological ageing in general and a determinant of organ function. In the arterial wall this is characterized by a reduction in the elastin content, as well as by an increased content of collagen and its cross-linkages, leading to increased arterial stiffness and elevated central as well as brachial blood pressure, accompanied by increa

New Tools for Understanding the Local Asymptotic Power of Panel Unit Root Tests

Motivated by the previously documented discrepancy between actual and predicted power, the present paper provides new tools for analyzing the local asymptotic power of panel unit root tests. These tools are appropriate in general when considering panel data with a dominant autoregressive root of the form ρi = 1 + ciN−κT−τ, where i = 1, ..., N indexes the cross-sectional units, T is the number of t

Tre frågor om diskriminering

Diskrimineringsterminologi förekommer på olika rättsliga nivåer: i internationell rätt, i grundlag och i vanlig nationell lagstiftning. Innebörden och användningen av ”diskriminering” varierar en del mellan olika rättsliga kontexter. Samtidigt vore diskriminering inte föremål för rättslig reglering på någon nivå om det inte betraktades som moraliskt problematiskt. Det rättsliga och det moraliska h
