Subparalyzing Doses of Rocuronium Reduce Muscular Endurance without Detectable Effect on Single Twitch Height in Awake Subjects

Purpose. To test the hypothesis that a low-dose rocuronium acts mainly by means of reducing muscular endurance rather than by reducing momentary force. Methods. In a randomized placebo-controlled double-blinded study, eight healthy volunteers were studied in two sets of experiments. In the first set, the subjects made a sustained maximum effort with the dominant hand for 80 seconds while squeezing

A method to determine binder content in small samples of cementitious material using hydrochloric acid and ICP-OES analysis

A method to determine the binder content in small samples of cementitious material is presented. Microstructural measurements such as sorption balance measurements or TGA (thermogravimetric analysis) require small samples; therefore cement paste is often used instead of mortar or concrete to get representative samples. However, normalizing measured results to a common basis, such as the binder con

Disability, socialism and autonomy in the 1970s : case studies from Denmark, Sweden and the United Kingdom

In the 1970s, grassroots disability movements in many countries changed the thinking around disability and disability politics. Nonetheless, they were also part of larger political upheavals in the western world. How were they inspired by the socialist, feminist, and gay and lesbian movements? In addition, how did they relate to non-disabled allies? Organisations in Denmark and Sweden are investig

Heritability of cilioretinal arteries: a twin study

AbstractPURPOSE: To determine whether the presence of one or more cilioretinal arteries, a distinct element of the pattern of fundus vessels, is genetically programmed, influenced by environmental factors, or the result of random mechanisms of vascular development. METHODS: The fundi of 112 pairs of healthy monozygotic and dizygotic twins were examined using digital fundus photography and visual a

Kinetics of Au-Ga Droplet Mediated Decomposition of GaAs Nanowires

Particle-assisted III-V semiconductor nanowire growth and applications thereof have been studied extensively. However, the stability of nanowires in contact with the particle and the particle chemical composition as a function of temperature remain largely unknown. In this work, we use in situ transmission electron microscopy to investigate the interface between a Au-Ga particle and the top facet

Anti-antropocentrism i poesi av Gunstein Backe, Katarina Frostenson och Ursula Andkjær Olsen

Exploring trends, implications and challenges for logistics information systems in omni-channels : Swedish retailers’ perception

Purpose: The purpose of this paper is to explore the current trends, implications and challenges of information systems (IS) related to omni-channel logistics. Design/methodology/approach: An exploratory survey study is conducted with 23 Swedish retail companies transforming to omni-channel logistics. The study investigates the retailers’ current situations regarding logistics IS as well as their

Heredity of small hard drusen in twins aged 20-46 years

Abstract PURPOSE: To examine the prevalence and heredity of small hard drusen in 220 healthy twins aged 20-46 years. METHODS: Grayscale digital fundus photography, four-field 50 degrees nonstereoscopic, in red-free illumination was performed in 58 pairs of monozygotic (MZ) twins and 52 pairs of dizygotic (DZ) twins as part of a detailed biometric characterization.

Effects of pseudophakic lens capsule opacification on optical coherence tomography of the macula

AbstractPURPOSE: To report observations on the influence of posterior lens capsule opacification on optical coherence tomographic imaging quality and measurements of macular thickness. METHODS: The retrospective study included 13 eyes in 12 patients of which 2 eyes had a healthy macula and 11 eyes had maculopathy. In all eyes posterior lens capsule fibrosis was present. A clinical examination incl

On time discretizations for the simulation of the settling-compression process

The simulation model for secondary settling tanks by Bürger et al. (2013) was introduced mainly to resolve spatial discretization problems when both hindered settling and the phenomena of compression and dispersion are included. Straightforward time integration unfortunately means long computationaltimes. The next step in the development is to introduce and investigate time-integration methods for

Lens ageing as an indicator of tissue damage associated with smoking and non-enzymatic glycation--a twin study.

Aims/hypothesis. With ageing the long-lived proteins of the human lens undergo denaturation by non-enzymatic glycation. The denaturated proteins are fluorescent, a property that can be assessed in vivo by fluorometry. Our aim was to examine the relative contribution of hereditary and environmental effects on the accumulation of fluorescent compounds in the lens.Methods. We examined 59 monozygotic
