We investigate a class of discrete distributions generated by expanding a parametric function in a Lagrange series. There is a close relationship to the class of generalized Poisson distributions, and special cases of our class of distributions arise in the context of random mapping theory. Unbiased estimation is discussed and the results are applied to inference problems in connection with two ra

A REE-bearing fluorosilicate from the Tommot REE-Nb deposit in Yakutia, Russia, described without a name in 1966, is characterized here as a new species, proshchenkoite-(Y), of the vicanite group of borosilicates. Wavelength-dispersive electron probe analyses gave the following empirical formula: (Y3.70REE7.54Ca1.55Na1.16Mn0.77Th0.10Pb0.01)(Sigma 14.83)(Fe0.832+M0.15Ti0.02)(Sigma 1.00)Ca-1.00 (P0.

We present a general model study of surface-enhanced resonant Raman scattering and fluorescence focusing on the interplay between electromagnetic effects and the molecular dynamics. Our model molecule is placed close to two Ag nanoparticles and has two electronic levels. A Franck-Condon mechanism provides electron-vibration coupling. Using realistic parameter values for the molecule we find that a

The aim was to determine whether outcome of unrelated donor transplantation for severe aplastic anemia has improved in recent years and whether this is due to patient selection or better transplant technology. We analyzed 498 patients transplanted during 1990-2005. By running univariate regression models dichotomizing year of transplantation we defined 1998 as the year of the most significant chan

Aim: To conduct a multi-language translation and cross-cultural adaptation of the Intermittent and Constant OsteoArthritis Pain (ICOAP) questionnaire for hip and knee osteoarthritis (OA). Methods: The questionnaires were translated and cross-culturally adapted in parallel, using a common protocol, into the following languages: Czech, Dutch, French (France), German, Italian, Norwegian, Spanish (Cas

In a recent paper,(1) we investigated how the interaction between two adsorbing surfaces in a polymer solution responds to changes of the intrinsic stiffness of the polymer chains. We demonstrated that as the chain rigidity is increased, starting from the fully flexible limit, a free energy barrier develops. In this work, we shall continue our studies of semiflexible polymers but focus on the othe

The sociology of research and knowledge use, argue the authors, could be a way of linking important parts of sociology, such as organization studies, the sociology of science to each other. In the article, they discuss the idea that organizational responses to environments are related to research utilization. Based upon an empirical investigation of city welfare departments, four empirical “utiliz

We investigated the relationship between nitric oxide (NO) and Na+,K+-ATPase (NKA) in the gill of anadromous Atlantic salmon. Cells containing NO-producing enzymes were revealed by means of nitric oxide synthase (NOS) immunocytochemistry and nicotinamide adenine dinucleotide phosphate diaphorase (NADPHd) histochernistry, which can be used as an indicator of NOS activity, i.e. NO production. Antibo

CD4+ T cells that recognize residues 256–270 of type II collagen (CII) associated with the I-Aq (Aq) molecule play a central role in disease pathogenesis in murine collagen-induced arthritis (CIA). Disease is most efficiently induced by immunization with heterologous CII, which elicits heterologous, e.g. bovine, CII256–270:I-Aq-specific T cells that only poorly cross-react with mouse CII. The self

Affinity precipitation of proteins uses polymers capable of reversible soluble-insoluble transitions in response to small environmental changes (temperature, pH or solvent composition). Here we describe protocols for (i) the synthesis of responsive polymers with specific affinity to target proteins and (ii) the purification of proteins using these polymers. The purification is based on precipitati

In this work a method was developed for characterisation of commercially available polymers consisting of mixtures of substituted cellulose and starch. Selective hydrolysis with specific enzymes was used to achieve separation of the two polymers in the mixture. Enzymes hydrolysing (1 -> 4)-alpha-D and (1 -> 6)-alpha-D-glycosidic bonds were used for the starch part and enzymes hydrolysing (1 -> 4)-

Background and purpose Early migration of joint replacements is an effect of poor fixation and can predict late loosening. By reducing the bone resorption after implantation of a joint replacement, it should be possible to enhance the initial fixation of the implant. We studied the effect of once-weekly treatment with alendronate after knee replacement. Patients and methods We recruited 60 patient

Background Pain at the site of intravenous injection of propofol is a common clinical finding. This double-blind, randomized cross-over study was designed to evaluate whether venous occlusion applied during injection of a low dose of propofol reduces the intensity of pain at the site of injection compared with no occlusion. Methods Bilateral 0.5-ml injections of an emulsion containing 10 mg/ml of

OBJECTIVES: A six country Pan-European study of aspects of urogenital ageing (UGA). METHODS: The study was carried out using a stratified random sample of 3000 women between the ages of 55 and 75 years. RESULTS: A total of 30% suffered from UGA symptoms, of whom 60% made efforts to alleviate their UGA problems, most commonly using HRT. There were some international differences regarding womens' pe
