The addition of locust bean gum but not water delayed the gastric emptying rate of a nutrient semisolid meal in healthy subjects
Background: Most of the previous studies regarding the effects of gel-forming fibres have considered the gastric emptying of liquid or solid meals after the addition of pectin or guar gum. The influence of locust bean gum, on gastric emptying of nutrient semisolid meals in humans has been less well studied, despite its common occurrence in foods. Using a standardised ultrasound method, this study
Hepatitis B virus DNA in serum and liver is commonly found in Chinese patients with chronic liver disease despite the presence of antibodies to HBsAg
Sera from 410 patients from the Wuhan area in the central part of China with the diagnosis of chronic liver disease were analyzed for markers of hepatitis B, C and D virus infections. All sera, plus liver biopsy specimens from 188 of the patients, were also tested for hepatitis B virus DNA by polymerase chain reaction. Sixty-eight percent were HBsAg positive in serum, whereas 29% showed markers of
Threadlike Micelles from Cetyltrimethylammonium Bromide in Aqueous Sodium Naphthalenesulfonate Solutions Studied by Static and Dynamic Light Scattering
Dynamic and static light scattering measurements have been made on both dilute and semidilute solutions of the threadlike micelles formed in equimolar mixtures of CTAB and sodium naphthalenesulfonate in aqueous solutions. In dilute solution (1 mM), the first normal mode of the chains (tj) was isolated from the contin decay time spectra as a function of measurement angle. The value of t¡ agreed wit
Nya rön om fragil X-syndromet komplicerar genetisk vägledning. Sjukdomsgenen orsakar fler symtom än vad som tidigare varit känt
The Swedish Medical Society’s Delegation for Medical Ethics held in October 2004 a workshop on the new ethical implications on genetic counselling in families where a premutation or mutation in the FMR1 gene was found. New research has revealed that premutation carrier women have an increased risk of premature ovarian failure, and, thus, their fertile sisters may be mutation carriers with an incre
Transition Probabilities Between High-spin States in 88Mo and 90Mo
The reactions (Ni(Ar, alpha2p)Mo)-Ni-58-Ar-36-Mo-88 and (Ni(Ar, 4p)Mo)-Ni-58-Ar-36-Mo-90 at 149 and 140 MeV beam energies have been used to carry out Doppler shift attenuation and recoil distance lifetime measurements and to determine DCO ratios in Mo-88 and Mo-90. A singles angular distribution experiment using the reaction (Ni(Cl, 3p)Mo)-Ni-59-Cl-35-Mo-90 has been performed at 120 MeV beam energ
Synthese Vol 149 No. 3 Metaphysics in Science
This volume contains essays by five British philosophers and one Swedish philosopher working in metaphysics and in particular metaphysics as it relates to the philosophy of science. These philosophers are the core of a tight network of European philosophers of science and metaphysicians and their essays have evolved as a result of workshops in Lund, Edinburgh, and Athens.
Self-diffusion in two- and three-dimensional powders of anisotropic domains: An NMR study of the diffusion of water in cellulose and starch
The pulsed field gradient stimulated echo NMR technique is applied to the study of water diffusion in biological porous materials (a sheet of wood cellulose fibers and a packed bed of potato starch granules) consisting of randomly oriented domains with an anisotropic supermolecular organization. Expressions are presented for the probability distribution of apparent diffusion coefficients due to tw
Particle size and crystallinity dependent electron injection in Fluorescein 27-sensitized TiO2 films.
Influence of processing parameters, such as autoclaving and firing temperature, on the optical properties of nanocrystalline anatase TiO2 film and on the process of electron injection from the dye fluorescein 27 to the as-prepared films is studied. Transmission electron microscopy and steady-state and time-resolved femtosecond spectroscopy measurements indicate that the larger the TiO2 particle an

Popular Abstract in Swedish Syftet med den här studien är att undersöka utvecklingen av språkfärdigheten i skriftlig produktion av franska som främmande språk. Vi har följt 5 inlärares produktion av franska i en 30 månader lång longitudinell studie. För att kunna utvärdera färdigheten har vi använt oss av parametrarna flyt, komplexitet och korrekthet. Flyt och komplexitet har utvärderats med hjälpThe aim of this study is to examine the development of linguistic proficiency in written production of second-language French. In a longitudinal study of 30 months, we follow the written production of 5 guided learners of French as a second language. In order to apprehend proficiency we use the conventional parameters fluency, complexity and accuracy. The fluency and complexity are apprehended by

Observer-based Strict Positive Real (SPR) Switching Output Feedback Control
This paper considers switching output feedback control of linear systems and variablestructure systems. Theory for stability analysis and design for a class of observer-based feedback control systems is presented. It is shown how a circlecriterion approach can be used to design an observerbased state feedback control which yields a closedloop system with speci ed robustness characteristics. The ap
Macromolecular crowding and its conequences
Incompatible pairs of polymers separate into two phases in aqueous solution above a few percentage points total concentration. Protein pairs can also produce phase separation, but at somewhat higher concentrations. In this chapter, we explore the effect of high background concentrations of macromolecules on phase separation of pairs of species which would not be at sufficiently high concentration

Beyond neopositivists, romantics, and localists: A reflexive approach to interviews in organizational research
In this article I develop a framework for thinking about the research interview, and I critique dominating neopositivist and romantic views on the interview. I suggest eight metaphors that offer reconceptualizations of the interview, drawing upon recent theoretical trends on language, the subject, and discourse, and develop a reflexive theoretical framework. The article provides new ways of dealin
Antigen-independent binding of rat immunoglobulins in a radioimmunoassay. Solutions to an unusual background problem
A high non-specific binding of immunoglobulins to plastic surfaces was noted with a number of rat sera, when tested in an indirect 125I-labeled protein-A assay for detection of cell-surface-bound rat immunoglobulins of various classes and IgG subclasses. This type of non-specific binding was found with all types of Ig. The degree of binding varied with the type of test plate used and fluctuated wi
