Intuitionistic epistemic logic, Kripke models and Fitch's paradox
The present work is motivated by two questions. (1) What should an intuitionistic epistemic logic look like? (2) How should one interpret the knowledge operator in a Kripke-model for it? In what follows we outline an answer to (2) and give a model-theoretic definition of the operator $K$. This will shed some light also on (1), since it turns out that $K$, defined as we do, fulfills the properties
Flow field-flow fractionation: Critical overview.
This overview regards some critical issues in performing flow field-flow fractionation (flow FFF, FlFFF, AF4, HF-FlFFF, HF5). It includes the channel thickness, void time, channel-flow parabolic profile, channel-flow velocity gradient, uniformity of the cross-flow, sample injection time, relaxation/focusing time, width of sample starting zone, retention level, theoretical and experimental zone bro
Understanding quantitative structure-property relationships uncertainty in environmental fate modeling
In cases in which experimental data on chemical-specific input parameters are lacking, chemical regulations allow the use of alternatives to testing, such as in silico predictions based on quantitative structureproperty relationships (QSPRs). Such predictions are often given as point estimates; however, little is known about the extent to which uncertainties associated with QSPR predictions contri
Protein adsorption and complement activation for di-block copolymer nanoparticles
Four types of nanoparticles with core-diffuse shell structures have been synthesized through self-assembly of PICBA-Dextran block copolymers. These nanoparticles are designed to carry pharmaceutically active molecules into the human body through injection into the blood stream. In this work, we have determined how the characteristics of the diffuse shell influence the adsorption of three types of
Electron spectroscopic studies of nanowires formed by (GaMn)As growth on GaAs(111)B
Valence band photoemission with photon energies around the Mn2p excitation threshold has been used to study the development of nanowires catalyzed by MnAs particles. A gradual change in the spectra with increasing nanowire length is observed, such that the resonant photoemission eventually dominates over the Auger decay channel. The change is ascribed to dilution of Mn, showing that Mn is transfer
Search for New Particles in Two-Jet Final States in 7 TeV Proton-Proton Collisions with the ATLAS Detector at the LHC
A search for new heavy particles manifested as resonances in two-jet final states is presented. The data were produced in 7 TeV proton-proton collisions by the LHC and correspond to an integrated luminosity of 315 nb(-1) collected by the ATLAS detector. No resonances were observed. Upper limits were set on the product of cross section and signal acceptance for excited-quark (q*) production as a fu
Multicenter Patch Testing With a Resol Resin Based on Phenol and Formaldehyde Within the International Contact Dermatitis Research Group.
Contact allergy to phenol-formaldehyde resins (PFRs) based on phenol and formaldehyde is not detected by a p-tertiary-butylphenol-formaldehyde resin included in most baseline patch test series.
Medication beliefs and self-reported adherence-results of a pharmacist's consultation: a pilot study
Objectives Clinical outcomes in the secondary prevention of cardiovascular disease depend on the patients' adherence to prescribed medicines. Motivational interviewing (MI) is a patient-centred approach used to change different health behaviours. The objective of this pilot study was to explore the impact of a clinical pharmacist's consultation on beliefs about medicines and self-reported medicati
A GH57 4-α-glucanotransferase of hyperthermophilic origin with potential for alkyl glycoside production.
4-α-Glucanotransferase (GTase) enzymes (EC 2.4.1.25) modulate the size of α-glucans by cleaving and reforming α-1,4 glycosidic bonds in α-glucans, an essential process in starch and glycogen metabolism in plants and microorganisms. The glycoside hydrolase family 57 enzyme (GTase57) studied in the current work catalyzes both disproportionation and cyclization reactions. Amylose was converted into c
Effect of Everolimus Introduction and Calcineurin Inhibitor Reduction on Graft Vasculopathy in Heart Transplant Recipients
Efficient but getting wet feet. A not-entirely-frivolous note on the side-effects of growth-promoting institutions
Using data covering 38 countries across the 1965–2005 period, this paper shows that former British colonies tend to exhibit higher levels of carbon dioxide emission than other countries.
Myocardial Metabolism and Function During Induced Endotoxaemia and Hemorrhagic Shock in a Porcine Model
Formation of highly structured cubic micellar lipid nanoparticles of soy phosphatidylcholine and glycerol dioleate and their degradation by triacylglycerol lipase
Lipid nanoparticles of reversed internal phase structures, such as cubic micellar (I2) structure show good drug loading ability of peptides and proteins as well as some small molecules. Due to their controllable small size and inner morphology, such nanoparticles are suitable for drug delivery using several different administration routes, including intravenous, intramuscular and subcutaneous inje
Comparison of clinicians and an artificial neural network regarding accuracy and certainty in performance of visual field assessment for the diagnosis of glaucoma.
Purpose: To compare clinicians and a trained artificial neural network (ANN) regarding accuracy and certainty of assessment of visual fields for the diagnosis of glaucoma. Methods: Thirty physicians with different levels of knowledge and experience in glaucoma management assessed 30-2 SITA Standard visual field printouts that included full Statpac information from 99 patients with glaucomatous
Low-order feedforward controllers: Optimal performance and practical considerations
Feedforward control from measurable disturbances can significantly improve the performance in control loops. However, tuning rules for such controllers are scarce. In this paper design rules for how to choose optimal low-order feedforward controller parameter are presented. The parameters are chosen so that the integrated squared error, when the system is subject to a step disturbance, is minimize
Patterns and magnitude of Zn:Ca in otoliths support the recent phylogenetic typology of Salmoniformes and their sister groups
La chimie des otolithes de poissons sert a associer les poissons a des environnements specifiques. La chimie des otolithes peut aussi potentiellement servir d'outil dans la recherche phylogenetique, comme nous le demontrons ici chez les poissons salmonides et les taxons apparentes. Des cartes bidimensionnelles de la chimie de Zn:Ca dans les otolithes montrent des oscillations annuelles d'amplitude
Consumer Perceptions of Food Packaging: Contributing to or Counteracting Environmentally Sustainable Development?
Packaging has a fundamental role in ensuring safe delivery of goods throughout supply chains to the end consumer in good condition. It also has great potential to contribute to sustainable development. This paper explores and provides insights on Swedish consumer perceptions and knowledge of environmental aspects of food packaging and elaborates on how these can contribute to or counteract environ
