The occurrence of wintering and spring-staging sea ducksin the southern part of Swedish Öresund was surveyedfrom air and ship during the period 2001–2011. Altogether22 air and 20 boat surveys were made during themonths November–May and here we present the resultsregarding five commonly recorded sea ducks. We presentthe numbers recorded and the general time pattern of occurrenceduring winter and sp
Spectrophotometric equilibrium measurements indicate formation of the complexes [Pd(H2O)(3)HSO4](+) and [Pd(H2O)(3)SO4] in the reaction between [Pd(H2O)(4)](2+) and hydrogen sulfate/sulfate in the region: 0.10 less than or equal to [H+] less than or equal to 0.80 M. The stability constants are 0.7 +/- 0.2 and 19 +/- 6 M-1, respectively, at 25 degrees C and 1.00 M ionic strength. The protolysis con
Objectives Regulations heavily control medical technology (MT), which often includes information technology (IT), but staff experiences related to these regulations are unknown. The study aim was to assess Swedish IT/MT staff experiences regarding regulations for medical devices and medical information systems. Methods An anonymous, ten-item, self-report questionnaire was administered to IT and MT
Access to palliative care is unequally distributed across Sweden and thus does not meet the needs. The holistic perspective of palliative care is sometimes contrasted with the usual medical focus on organ failure and disease. Palliative consultation teams provide specialist palliative care competencies for staff caring for patients in primary care, nursing homes and in hospitals. Efforts to increa
Fast substitution of chloride for bromide and iodide trans to triphenylsilyl in trans-PtCl(SiPh3)(PMe2Ph)2 has been studied by stopped-flow spectrophotometry in acetonitrile solution. Substitution is reversible with an observable solvent path via the solvento complex trans-[Pt(SiPh3)(MeCN)(PMe2Ph)2]+, which has also been synthesized and characterized in solution. Rate constants for the forward and
Reduction of [AuCl4]- and trans-[Au(CN)2X2]- (X = Cl, Br) by sulfur(IV) as SO2.nH2O, HSO3-, and SO3(2-) has been studied at 25-degrees-C in aqueous solution with ionic strength 1.0 M and 0 < pH < 2.3 by use of stopped-flow spectrophotometry. Redox takes place directly without initial substitution at the gold(III) centers with stoichiometry Au(III):S(IV) = 1:1 and with Au(I) complexes and HSO4- as
We investigate the effects of the orientation of the magnetic field and the orientation of a quantum dot, with respect to crystallographic coordinates, on the quality of an electrically controlled qubit realized in a gated semiconductor quantum dot. We find that, due to the anisotropy of the spin-orbit interactions, by varying the two orientations it is possible to tune the qubit in the sense of o
Thin films of "complex salts" (CS = ionic surfactants with polymeric counterions) have recently been shown to respond to humidity changes in ambient air by changing their liquid crystalline structure. We here report isotherms and kinetics of water sorption/desorption for ∼10-100 μm films of alkyltrimethylammonium polyacrylate CS, measured in a dynamic gravimetric vapor sorption instrument over a 0
This paper focuses on mapping the different losses present in an Insert Permanent Magnet Synchronous Machine (IPMSM). The machine is designed as a traction machine according to the requirements of a parallel hybrid electric heavy vehicle. This includes a wide constant power range and overload capability, all to be fitted in a strictly limited space in the vehicle. In order to meet the requirements
This paper deals with the need of developing a method that can assist designers to select appropriate solarcontrol mechanisms in highly glazed spaces, in order to provide enhanced daylight and views while avoidingoverheating. The development of the method is based on real life needs and was initiated by an actual projectthat we, as building physicists / façade consultants were called in to assist.
The thesis aims to compare two approaches to psychosocial rehabilitation – day centres and clubhouses – and to explore if either appears better suited to support people in mental health recovery. The recovery focus is on opportunities for engaging in meaningful daily occupations, accessibility to social interaction and factors pertaining to perceived health and well-being. The thesis consists of f
This study sought to analyse antimicrobial pressure, indications for treatment, and compliance with treatment recommendations and to identify possible problem areas where inappropriate use could be improved through interventions by the network of the local Swedish Strategic Programme Against Antibiotic Resistance (Strama) groups. Five point-prevalence surveys were performed in between 49 and 72 pa
We present mid-infrared laser-induced thermal grating spectroscopy (IR-LITGS) using excitation radiation around 3 μm generated by a simple broadband optical parametric oscillator (OPO). Acetylene as a typical small hydrocarbon molecule is used as an example target species. A mid-infrared broadband OPO pumped by the fundamental output of a neodymium-doped yttrium aluminum garnet (Nd:YAG) laser was
We have developed the Yeast Pathway Kit (YPK) for rational and random metabolic pathway assembly in Saccharomyces cerevisiae using reusable and redistributable genetic elements. Genetic elements are cloned in a suicide vector in a rapid process that omits PCR product purification. Single-gene expression cassettes are assembled in vivo using genetic elements that are both promoters and terminators
The aim of this study was to investigate non-solvent precipitation of starch to produce nanoparticles that could be used in Pickering emulsions. The material used was waxy maize, modified with octenyl succinic anhydride. Different methods of non-solvent precipitation were investigated, and a method based on direct mixing of an 8% starch solution and ethanol (ratio 1:1) was found to produce the sma
Abstract: Many species in the family Paridae, such as marsh tits Poecile palustris, are large-scale scatter hoarders of food that make cryptic caches and disperse these in large year-round territories. The perhaps most well-known species in the family, the great tit Parus major, does not store food itself but is skilled in stealing caches from the other species. We have previously demonstrated tha
Quantum chemical geometry optimisations have been performed on realistic models of the active site of myoglobin using density functional methods. The energy of the hydrogen bond between the distal histidine residue and CO or O2 has been estimated to be 8 kJ/mol and 32 kJ/mol, respectively. This 24 k J/mol energy difference accounts for most of the discrimination between CO and O2 by myoglobin (abo
Background: Effective interventions are needed to increase physical activity in the general population. To target interventions, we need knowledge of insuffciently active groups in society. This study aims to identify demographic and health-related correlates of leisure-time physical inactivity in a general Scandinavian population. Methods: Study participants comprised 5734 control subjects, age 1
