InAs has been grown on W-GaAs patterned substrates using MOVPE. The selectivity of the growth and the nucleation process has been studied as a function of the temperature and the V/III-ratio in the MOVPE reactor. It is shown that the W guides the nucleation of the InAs on the GaAs and that the islands formed may be used to embed metal features in a hybride InAs/GaAs structure in agreement with pre
Hybrid systems combining solid oxide fuel cells and gas turbines (SOFC/GT) have been extensively studied in recent years. They show very high theoretical electrical efficiencies and are considered as prime contenders for distributed generation. The addition of a CO2-capture system could make them even more attractive from an environmental perspective. In this study, a SOFC/GT configuration with an
Dysphagia is a common symptom in stroke patients, and malnutrition is prevalent among these patients. Thus far, nutritional effects of dysphagic treatment have not been evaluated. The aim of the present report was to study the effects of swallowing techniques on nutritional and anthropometric variables. A survey with follow-up was performed at the Departments of Geriatric Medicine and Neurology, M
The prognosis of depression in elderly people is reported as poor, with high mortality and high rate of non-recovery. The aim of this study was to investigate the outcome after 6 years in a broader perspective. In addition to the risk of dying, we also estimated the risk of moving to long-term care, and having a depression in a re-screening event after 6 years. In 1993, a screening event for depre
The CLEAR supports were originally developed for solid-phase synthesis. In this study, two wide-pore versions of the resins were prepared by radical suspension polymerization using toluene as the porogen. Trimethylolpropane ethoxylate (14/3 EO/OH) triacrylate was used as the cross-linking agent. Resins of two different porosities were synthesized. The permeability to biological macromolecules was
The rheological properties of gels of hydrophobically modified potato starch (HMPot) and high amylopectin potato starch (HAPP) were studied by small deformation oscillatory rheometry. The hydrophobic modification consisted of octenyl succinate anhydride (OSA) chains grafted mainly on the amylopectin molecules. The theological behaviour of HMPot was different from the behaviour of native potato sta
Hemicelluloses, which are abundant in nature and have potential use in a wide variety of applications, may make an important contribution in helping relieve society of its dependence on petrochemicals. However, cost-efficient methods for the isolation of hemicelluloses are required. This article presents an economic evaluation of a full-scale process to isolate hemicelluloses from process water fr
The Central Scandinavian Dolerite Group (CSDG) occurs in five separate complexes in central Sweden and SW Finland. U-Pb baddeleyite ages of dolerite dikes and sills fall into three age intervals: 1264-1271 (the Dalarna complex), 1256-1259 (the Vdsterbotten-Ulvo-Satakunta complexes) and similar to 1247 Ma (the Jamtland complex). Timing and spatial distribution of CSDG are unlike expressions of the
This study investigated the competitive adsorption between milk proteins and model milk membrane lipids at the oil-water interface and its dependence on the state of the lipid dispersion and the formation of emulsions. Both protein and membrane lipid surface load were determined using a serum depletion technique. The membrane lipid mixture used was a model milk membrane lipid system, containing di
A study of optical and transport properties of semiconductor quantum well structures subjected to nanoimprint lithography (NIL), with its pressure and temperature cycles, has been undertaken to ascertain if this lithography technique induces detrimental changes in these properties of the active layers over a range of pressures and temperatures, typically used in this printing process.

New and improved preparative routes to the previously known PCP ligands cis-1,3-bis(di-isopropylphosphinito)cyclohexane and cis-1,3-bis[(di-tert-butylphosphino)methyl]cyclohexane are reported. They react with 1 equivalent of dichloro(1,5-cyclooctadiene)platinum(II) [(COD)PtCl2] to give the cis coordinated complex cis-[PtCl2{cis-1,3-bis(di-isopropylphosphinito)}cyclohexane] and the Csp3-H activated
The effect of a study day on the subject of pain for nurses working at the thorax surgery department The aims of this investigation were: to describe patients' evaluation of pain and the treatment of pain after thorax surgery via sternotomy; to repeat the evaluation with another group of patients following a study day for nurses, featuring pain and pain treatment; and to examine whether the study
The detailed influence of ferrocene in a low-pressure, fuel-rich, laminar, premixed propene/oxygen/ argon flat flame was investigated experimentally using molecular beam sampling mass spectrometry (MBMS), laser-induced fluorescence (LIF), and compared to numerical simulations. MBMS was applied to analyze the species profiles of important intermediates in the flames with and without ferrocene dopin
Recent experimental data have established some of the basic features of multiple interactions in hadron-hadron collisions. The emphasis is therefore now shifting, to one of exploring more detailed aspects. Starting from a brief review of the current situation, a next-generation model is developed, wherein a detailed account is given of correlated flavour, colour, longitudinal and transverse moment
Human neutrophils are activated by the beta-galactoside-binding lectin galectin-3, provided that the cells are primed by in vivo extravasation or by in vitro preactivation with, for example, LPS. Removal of terminal sialic acid can change neutrophil functionality and responsiveness due to exposure of underlying glycoconjugate receptors or change in surface charge. Here, we investigated whether suc
In order to investigate the effects of conservation in liquid nitrogen and formalin on peripheral vascular tissue (abdominal aortic, femoral and flank artery tissue) laser-induced fluorescence spectra were recorded during the exposure of these tissues to He-Cd radiation (442 nm). The spectral distribution of tissue fluorescence allowed the development of simple algorithms based on the intensity di
Complexation of o-phthalate (1,2-benzenedicarboxylate) and competitive complexation of phosphate and phthalate at the goethite-water interface have been studied in 0.1 M Na(NO3) media at 298.2 K within the range 3.0 < -log [H+] < 8.5. Equilibrium measurements were performed as potentiometric titrations supplemented with spectrophotometric phosphate and phthalate analyses. The binary and ternary ch
Context: When using the Case Method in teaching situations, problem-solving is emphasized and taught, in order to acquire the skills and later be able to apply them in new situations. The basis of the learning process is the students’ own activity in the situation and is built on critical appraisal and discussion. Objectives: To explain what the Case Method is, what it is not and to describe when
