New measurements of radiative lifetimes of four 3d⁶5s levelsin Fe II at about 10 eV are presented along with absolute oscillator strengths for twenty 4p-5s transitions involving the four levels. The experimental measurements are compared with two different sets oftheoretical calculations. The lines are of particular interest in the modeling of HLyalpha pumped fluorescence of Fe II in as

Väderdata från 10 olika meterologiska mätstationer i Sverige - Kiruna, Luleå, Frösön, Söderhamn, Karlstad, Bromma, Jönköping, Säve, Ronneby och Sturup - för tidsperioden 1961 till 1990. De aktuella väderparametrarna är temperatur, relativ fuktighet, ånghalt, mättnadsånghalt, vindhastighet, vindriktning, nederbörd, solstrålning och långvågig strålning.

An alpha/beta barrel is predicted for the three-dimensional (3D) structure of Bacillus subtilis ferrochelatase. To arrive at this structure, the THREADER program was used to find possible homologous 3D structures and to predict the secondary structure for the ferrochelatase sequence. The secondary structure was fit by hand to the selected homologous 3D structure then the MODELLER program was used

OBJECTIVES: To estimate the total direct medical costs to society for patients with type 2 diabetes in Sweden and to investigate how different factors, for example diabetic late complications, affect costs. DESIGN: Cross-sectional data regarding health care utilization, clinical characteristics and quality of life, were collected at a single time-point. Data on resource use cover the 6-month perio

A flow-through microdispenser has been coupled to a micro HPLC separation system and used as a solvent elimination interface for Fourier transform infrared (FTIR) and Raman spectroscopic detection of the separated compounds. Using the microdispenser picoliter sized droplets can be generated and deposited on an appropriate target placed on a computerized x, y-stage. Evaporation of volatile solvent

The use of the extracting syringe (ESy), a fully automated membrane-based extraction technique, for analysis of phthalate esters in complex aqueous samples has been investigated. The ESy, working as an autosampler that combines the extraction process and injection into the gas chromatograph (GC) in one single step, is placed on top of the GC equipped with a flame ionisation detector. The aqueous s

A technique is presented here for evaluating the loss factor of a solid material element. This technique is commonly used in room acoustics to evaluate the reverberation time (RT) of rooms, and is therefore reviewed in this paper for applications in solid materials. The reverberation time is a quantity that describes the rate of decay of the sound level in the room, and is inversely proportional t

This paper presents a model for reversed-phase purification of insulin from desamido insulin. The system is described by a reaction dispersive model with a competitive Langmuir isotherm. A model building and calibration method is presented and the model's region of validity is defined. The model is calibrated using only two-component experiments on the raw mixture by the inverse method and then ex

The European Pre-Standard for protective clothing against cold ENV 342:1998 suggests that the testing of thermal insulation should be made on a moving thermal manikin. In this way the value can be used to match requirements specified by the IREQ-method or as realistic input for prediction of thermal stress in other standards. It is known from prior work that insulation values measured with human s

Extractability of red pigment from red beetroot was investigated using pulsed electric field (PEF) treated tissue in a solid-liquid extraction process. Thin disks of the tissue were subjected to PEF at different intensities and, 3-4 min after the treatment, the release of red pigment and ionic species into an isotonic solution was measured in situ using a spectrophotometer and a conductivity meter

MIMO has been proposed as an extension to 3G and Wireless LANs. As an implementation scheme of MIMO systems, V-BLAST is suitable for the applications with very high data rates. The square root algorithm for V-BLAST detection is attractive to hardware implementations due to its low computational complexity and numerical stability. In this paper, the fixed-point implementation of the square root alg

Pretreatment of mixed softwoods with SO2 impregnation and steam for production of ethanol has been investigated. The optimal conditions, both for sugar yield and ethanol yield, to assess the effect of inhibitors formed in the pretreatment, have been determined. The parameters investigated were: SO2 concentration (1-6% (w/w) dry matter), temperature (190-230 degrees C) and residence time (2-15 min)

A sparse mesh-neighbour based approximate inverse preconditioner is proposed for a type of dense matrices whose entries come from the evaluation of a slowly decaying free space Green's function at randomly placed points in a unit cell. By approximating distant potential fields originating at closely spaced sources in a certain way, the preconditioner is given properties similar to, or better than,

Many economic models contain the single variable 'money'. Money does not exist in the form of a single physical unit and it is common to construct monetary aggregates using the method of simple summations. Monetary aggregation theory lends little or no support to the method of simply summing various monetary asset components up to arbitrary levels of aggregation. In monetary aggregation theory, mo

A case study is presented in which two organisations have participated in a benchmarking initiative to discover improvement suggestions for their processes for managing product platforms. The initiative, based on an instrument which consists of a list of questions, has been developed as part of this study and contains eight major categories of questions that guide the participating organisations t
