Radiative lifetimes of GdI and GdII

Natural radiative lifetimes of 25 even-parity levels in Gd i (4f(7) 5d(2) 6p, 4f(7)5d6s6p and 4f(8)5d6s configurations) and 13 even-parity levels in Gd it (4f(7)5d6p and 4f(7)6s6p configurations) have been measured using the time-resolved laser-induced fluorescence technique in a laser-induced gadolinium plasma. The Gd I and Gd it levels range in energy from 26 866 to 36 395 cm(-1), and 25 960 to

Spectroscopic Atlas of Atmoshperic Microwindows in the Middle Infra-Red

This second edition of the infrared microwindow atlas contains a collection of spectral mi- crowindows commonly used or recently suggested for ground-based, high resolution, infrared solar absoption spectroscopy. These solar observations are aimed at quantifying the abun- dance of trace species in the terrestrial atmosphere. A microwindow is a narrow spectral interval that allows to observe a spec

A simple way to extract baddeleyite (ZrO2)

[1] Baddeleyite is a reliable geochronometer for dating the crystallization of mafic and other silica-undersaturated intrusive rocks. Its high U and negligible initial Pb content enable precise age determinations with statistical errors of a few million years or less. The widespread use of baddeleyite for dating has, however, been limited by the low content of baddeleyite in many samples and by di

Asymptotics for sums of random variables with local subexponential behaviour

We study distributions F on [0, infinity) such that for some T less than or equal to infinity F*(2)(x, x + T] similar to 2F(x, x + T]. The case T = infinity corresponds to F being subexponential, and our analysis shows that the properties for T < &INFIN; are, in fact, very similar to this classical case. A parallel theory is developed in the presence of densities. Applications are given to ran

On-line automated sample preparation for liquid chromatography using parallel supported liquid membrane extraction and microporous membrane liquid-liquid extraction

An automated system was developed for analysis of non-polar and polar ionisable compounds at trace levels in natural water. Sample work-up was performed in a flow system using two parallel membrane extraction units. This system was connected on-line to a reversed-phase HPLC system for final determination. One of the membrane units was used for supported liquid membrane (SLM) extraction, which is s

Review of books concerning Nils Rosén von Rosenstein

The Knee injury and Osteoarthritis Outcome Score (KOOS): from joint injury to osteoarthritis.

The Knee injury and Osteoarthritis Outcome Score (KOOS) was developed as an extension of the WOMAC Osteoarthritis Index with the purpose of evaluating short-term and long-term symptoms and function in subjects with knee injury and osteoarthritis. The KOOS holds five separately scored subscales: Pain, other Symptoms, Function in daily living (ADL), Function in Sport and Recreation (Sport/Rec), and

Effects of total parenteral nutrition on rat enteric nervous system, intestinal morphology, and motility.

Total parenteral nutrition (TPN) is often crucial for patients not being able to feed enterally or having intestinal absorptive deficits. Enteral nutrition is, however, frequently regarded vital for maintaining functional and structural intestinal integrity. The aim of this study was to investigate possible effects of TPN on rat distal small intestine compared to enterally fed identically housed c

Errors Associated with Experimental Determinations of Enzyme Flux Control Coefficients

An analysis is presented of the likely statistical error and mathematical bias of experimental enzyme flux control coefficient estimates, calculated from observations of the flux changes caused by finite changes of the concentration of an enzyme in a metabolic pathway. The results indicate that such control coefficients are not likely to be determined with satisfactory precision unless the experim

Electrochemical study of the XNA on Gold (TM) microarray

A novel electrode array was developed based on the XNA on Gold(TM) microarray platform. The platform combines self-assembling monolayers, thick film patterning and streptavidin based immobilization to provide a robust, versatile platform capable of analysing virtually any biomolecule including nucleic acids, proteins, carbohydrates and lipids. Electrochemical analysis of the self-assembling monola

Biomolecule Separation Using Temperature-Induced Phase Separation with Recycling of Phase-Forming Polymers

We review our recent work on the thermoseparating polymers in aqueous two-phase extractions of biomolecules. Random copolymers of ethylene oxide and propylene oxide (EOPO copolymers) are thermoseparating in water solution, i.e., at temperatures above the cloud point a concentrated copolymer phase and a water phase almost free of copolymer are formed. This phase behavior makes it possible to recycl

Modelling catalytic combustion of carbon monoxide and hydrocarbons over catalytically active wire meshes

A new way of preparing catalytically active wire meshes through a thermal-spray technique is described. A metal substrate (e.g. Kanthal AF) was plasma-sprayed with a composite ceramic/polymer-powder. The polymer content of the sprayed layer was burnt off whereupon a well-defined macro-porosity was created. By treating the so obtained material with an alumina-sol the specific surface area could be

Mesenchymal stem cell content of human vertebral bone marrow

Mesenchymal stem cells (MSCs) are capable of down-regulating alloimmune responses and promoting the engraftment of hematopoietic stem cells. MSCs may therefore be suitable for improving donor-specific tolerance induction in solid-organ transplantation. Cells from cadaveric vertebral bone marrow (V-BM), aspirated iliac crest-BM, and peripheral blood progenitor cells were compared. Cells were charac
