Efficient visible-light-driven photocatalysis can be achieved over conventional wide band gap semiconductor, in which iodinated SnO2 quantum dots (QDs) are synthesized via hydrolysis of crystalline SnI4 in the absence of any additives or templates. The formation of SnO2 QDs reveals a wide preparation window and a very fast growth rate in minute scale. The iodine species may only exist on the surfa
Here we investigate the feasibility of silver as seed-particle material to synthesize GaAs nanowires and show that both crystal phase and growth direction can be controlled by choice of substrate orientation. A (111)B substrate orientation can be used to form vertically aligned wurtzite GaAs nanowires and a (100) substrate orientation to form vertically aligned zinc blende GaAs nanowires. A 45-50%
The close relationship between young children’s living conditions and their healthlater in life is well documented and a safe and healthy environment during earlychildhood promotes cognitive functions and social development during the wholelifespan. Becoming a parent is a major life transition and it is sometimes described as a stressful and vulnerable time involving changes to lifestyle and routi
In the present work, multifunctional Ti-Si-N coatings have been deposited using CAVD method with the aim of studying their chemical, physical, structural and mechanical properties. Coatings of Ti-Si-N were modified by high-intensity ion implantation using copper ions with dose D = 2 × 1017 ions/cm2 and energy E = 60 keV. The results demonstrated that ion implantation has an effect on the grain siz
In sexually reproducing species, resources may theoretically be distributed with bias to the production of male or female offspring in response to the condition of the mother, commonly recognized as sex allocation. Using a recently characterized sex-specific molecular marker, we tested for maternal sex allocation (i.e. maternal primary sex ratio bias and sex-specific offspring investment) in capti
Background: Housing environments that hinder performance of daily activities and impede participation in social life have negative health consequences particularly for the older segment of the population. From a public health perspective accessible housing that supports active and healthy ageing is therefore crucial. The objective of the present study was to make an inventory of environmental barr
The authors have developed a porous silicon (P-Si) based duplex antibody microarray platform for simultaneous quantitation of the biomarkers prostate-specific antigen (PSA) and human glandular kallikrein 2 (hK2) in serum. Pore size-controlled P-Si surfaces have an extremely enlarged surface area that enables high-density immobilization of fluorescently labeled antibodies by physical adsorption. Au
This article aims to contribute to the understanding concerning the introduction of crisis psychotherapy in the 1970s in psychiatric clinics in Sweden. The article discusses how this psychotherapy became central in the work of the clinics in supporting patients to well-being and inner growth. The ambition was that patients in an acute crisis-situation would be offered care immediately, aiming at a
Abstract in FrenchDecay-prediction models can be used to predict the service life of wooden components. However, knowledge of how the material climate, i.e. moisture content and material temperature, varies with time is required. A reliable material climate prediction model is therefore crucial in situations when measurements are not viable. The aim of this paper is to develop and assess the perfo
System Dynamics (SD) is a method that allows for integrated modelling of technical as well as managerial aspects responsible for the dynamic complexity of systems. Therefore, simulation of SD models can also be a tool for problem analysis within software organisations. In this paper, experience with SD modelling of software processes and projects within Siemens is reported. Special focus is put on
Follow-up of endovascular aneurysm repair (EVAR) with life-long computed tomography angiography (CTA) surveillance exposes patients with impaired renal function to repeated risks of contrast medium-induced nephropathy (CIN).
At the end of the 19th century, Wilhelm Windelband proposed a distinction between nomothetic and idiographic re-search, which became highly relevant for the discussion of the nature of psychological science. During the 20th cen-tury, a number of writers (including William Stern, Gordon Allport, James Lamiell and David Magnusson) have criti-cized the focus on variables rather than persons, and popu
This is the first part of a series of papers devoted to direct and inverse scattering of transient waves in lossy inhomogeneous media. The medium is assumed to be stratified, i.e., it varies only with depth. The wave propagation is modeled in an electromagnetic case with spatially varying permittivity and conductivity. The objective in this first paper is to analyze properties of the scattering op
BACKGROUND: Liver resection is a possibly curative treatment for colorectal cancer (CRC) liver metastases. Preoperative chemotherapy may make initially irresectable tumors resectable. The aim of this study was to compare perioperative course and short-term mortality after liver resection for CRC metastases between patients who were and were not treated with preoperative chemotherapy. METHODS: Pati
Aims: This study summarises the health-related quality of life (HRQOL) scores and absenteeism caused by sinus problems in patients awaiting surgery with the diagnoses recurrent acute rhinosinusitis (RARS), chronic rhinosinusitis with nasal polyps (CRS+NP) or CRS without nasal polyps (CRS-NP), in a prospective multi-centre study. Methodology: Two hundred and seven patients with RARS, CRS+NP or CRS-
The stacked multi-level (SML) klystron modulator topology has been suggested as an alternative to conventional pulse transformer based topologies in an attempt to improve output pulse performance and reduce system size for long pulse applications. In this topology, a power converter chain including a high frequency transformer generates the output pulse in a pulse modulation/demodulation scheme, e
Aim: The aims of this study were to evaluate health-related quality of life (HRQoL) in children with sacrococcygeal teratoma and to explore the effect of the scar on physical, emotional and behavioral aspects. Methods: A cohort of children operated on for sacrococcygeal teratoma between 2000 and 2013 at Lund University Hospital, Sweden, and their parents were interviewed. HRQoL was evaluated with
The aim of this study was to establish a rapid method for in vivo quantification of a large range of flow velocities using phase information. A basic gradient-echo sequence was constructed, in which flow was encoded along the slice selection direction by variation of the amplitude of a bipolar gradient without changes in sequence timings. The influence of field inhomogeneities and eddy currents wa
