Metal nanoclusters, supported on inert substrates, exhibiting well-defined shapes and sizes in a broad range of temperatures are a major object of desire in nanotechnology. Here, a technique is presented that improves the thermal stability of monodisperse and crystalline transition metal nanoclusters grown in a regular array on metal-supported graphene. To stabilize the clusters after growth under

Helianthemum oelandicum var. canescens (Hartm.) Fr. is an endemic taxon with a restricted distribution (less than 10 km2) in the southernmost part of the Baltic island of Öland, SE, Sweden. The taxon varies with respect to stellate hairs. Most plants can be classified into two morphs, the stellated morph (with a dense carpet of stellate hairs on the abaxial surface of the leaves) and the bristled

The purpose of this article is to analyze how university teachers’ professionalism shapes the coordination processes in higher education institutions (HEIs). By developing an innovative framework, which combines governance theories and theories about professionalization, we found that university teachers’ roles in coordination with governance actors in HEIs follow two different logics: to comply w

Urban environments pose novel challenges, as well as opportunities, for urban-dwelling wildlife. Although differences have been reported in several phenotypic traits (e.g. morphology, physiology and behaviour) between urban and rural populations, it is poorly understood whether this affects individual fitness. Telomere dynamics are posited as one possible mechanism underlying senescence and mortal

In two-particle angular correlation measurements, jets give rise to a near-side peak, formed by particles associated to a higher-pT trigger particle. Measurements of these correlations as a function of pseudorapidity (Δη) and azimuthal (Δφ) differences are used to extract the centrality and pT dependence of the shape of the near-side peak in the pT range 1

Endovascular redo aortic operations are a challenging undertaking. Techniques for treatment date almost as far back as the original open repair itself. Risk factors for failure following aortic repair include larger abdominal aortic aneurysm necks, severe neck angulation, as well as clinical variables such as age, family history, obesity and chronic obstructive pulmonary disease. The armamentarium

Objective Endoscopic pituitary surgery has shown favorable clinical outcomes. Less is known about the impact of surgical approaches on health-related quality of life (HRQoL) and work capacity. The present study was undertaken to compare transsphenoidal microscope-assisted surgery with endoscopic transsphenoidal surgery regarding preoperative and surgical factors for the final outcome of HRQoL and

Background: The home is imperative for the possibilities for meaningful everyday activities among people with psychiatric disabilities. Knowledge of whether such possibilities vary with type of housing and housing support might reveal areas for improved support. We aimed to compare people with psychiatric disabilities living in supported housing (SH) and ordinary housing with support (OHS) regardi

Objectives: Irreversible electroporation (IRE) is a new modality for tumor ablation. Electrodes are placed around the tumor, and a pulsed, direct current with a field strength of 2000 V/cm is delivered. The direct current drives cells into apoptosis and cell death without causing significant heating of the tissues, which spares the extracellular matrix and proteins. The purpose of this review was

Purpose: To determine the impact of socioeconomic position (SEP) and distance to provider on outpatient mental health care utilization among incident users of antidepressants. Method: A nationwide register-based cohort study of 50,374 person-years. Results: Persons in low SEP were more likely to have outpatient psychiatrist contacts [odds ratio (OR) 1.25; confidence interval (CI) 1.17–1.34], but l

A search for strongly produced supersymmetric particles using signatures involving multiple energetic jets and either two isolated same-sign leptons (e or μ), or at least three isolated leptons, is presented. The analysis relies on the identification of b-jets and high missing transverse momentum to achieve good sensitivity. A data sample of proton-proton collisions at s=13 TeV recorded with the A

Objective/Background The objective was to evaluate the feasibility and mid-term outcomes of endoconduits (EC) with the “pave and crack” technique during endovascular aneurysm repair (EVAR) of varying complexity. Methods This was a retrospective study. All patients undergoing EC between July 2009 and October 2015 were included. The primary endpoint was technical success of the EC defined as the abi

Objective To evaluate the feasibility of continuous longitudinal intravenous infusion of recombinant human insulin-like growth factor-1/recombinant human insulin-like growth factor binding protein-3 (rhIGF-1/rhIGFBP-3) for prevention of retinopathy of prematurity and other complications in extremely preterm infants (< 28 weeks' gestational age), based on initial sections of a phase II randomized c

Background: The effects of "maternal environment" on fetal development have been studied since the eighties, but the results regarding the features which influence mother-fetus relationship are inconsistent. Aim: To develop a mother-fetus relationship assessment scale on a Hungarian sample, and to reveal the factors that determine mother-fetus bonding. Method: 114 pregnant women, between 15 and 38

An ultrasonically-enhanced mechanochemical method was developed to synthesize CaFe-layered double hydroxides (LDHs) with various interlayer anions (CO3 2−, NO3 −, ClO4 −, N3 −, F−, Cl−, Br− and I−). The duration of pre-milling and ultrasonic irradiation and the variation of synthesis temperature in the wet chemical step were investigated to obtain the optimal parameters of preparation. The main me

In this work, we generalize the recent sparse iterative covariance-based estimator (SPICE) by extending the problem formulation to allow for different norm constraints on the signal and noise parameters in the covariance model. The resulting extended SPICE algorithm offers the same benefits as the regular SPICE algorithm, including being hyper-parameter free, but the choice of norms allows further

Biografisk artikel om språkvetaren m m Hjalmar Edgren (1840-1903) med tonvikt på hans period som docent vid Lunds universitet 1880-1885 samt de kontakter med andra lundaakademiker han därvid skaffade sig.

Ribs are often employed in internal cooling passages of turbine blades to augment heat transfer with cooling air flowing through the internal ribbed passages. The present work concentrates on truncated ribs to improve thermal performances with continuous ribs in a high aspect ratio channel. With various truncation types and arrangements of truncated ribs, the optimized thermal performance of ribbe

I Lunds universitets strategiska plan för 2012-2016 framhålls att man vill ”vidareutveckla det akademiska lärarskapet”. All utbildning vid lärosätet ska hålla högsta kvalitet och man ska erbjuda attraktiva och akademiskt framstående lärandemiljöer. Detta åstadkoms bland annat genom att universitetets lärare kan ”arbeta med ett forskande förhållningssätt, både i förhållande till studenternas lärand

Although a causative role of α-synuclein (α-syn) is well established in Parkinson’s disease pathogenesis, available animal models of synucleinopathy do not replicate the full range of cellular and behavioral changes characteristic of the human disease. This study was designed to generate a more faithful model of Parkinson’s disease by injecting human α-syn fibril seeds into the rat substantia nigr
