Implications of migratory connectivity for species' ranges and subspeciation of arctic shorebirds

The longitudinal spread zone was investigated for 30 arctic shorebird populations from 10 different wintering communities in widely different regions of both the Northern and Southern Hemispheres. Information about total breeding and wintering ranges, migratory connectivity and subspecies was compiled from literature sources. The spread of the distributions was analysed in relation to the mean dis

Characterization of endotoxin and 3-hydroxy fatty acid levels in air and settled dust from commercial aircraft cabins.

Endotoxin was measured in air and dust samples collected during four commercial aircraft flights. Samples were analyzed for endotoxin biological activity using the Limulus assay. 3-hydroxy fatty acids (3-OH FA) of carbon chain lengths C10:0-C18:0 were determined in dust by gas chromatography-ion trap tandem mass spectrometry. The geometric mean (geometric standard deviation) endotoxin air level wa

Molecular identification and developmental expression of UV and green opsin mRNAs in the pineal organ of the Atlantic halibut.

The pineal organ is the only differentiated photoreceptor organ present in embryos and early larvae of the Atlantic halibut (Hippoglossus hippoglossus). We investigated the molecular identity of opsins in the pineal organ, and their expression during different life stages. Using RT-PCR we identified two 681-bp gene sequences, named HPO1 and HPO4, in cDNA from adult pineal and whole embryos. The pr

Ultrafiltration of kraft black liquor from two Swedish pulp mills

Extraction of lignin by ultrafiltration of black liquor from two Swedish pulp mills has been studied. One of the mills employs batch digestion and the other continuous digestion. At both mills softwood was used as raw material. The black liquor was withdrawn before the evaporator unit. A ceramic membrane with a cut-off of 15 000 g mol(-1) was used in the experiments. The average flux during concen

Neuroblastoma as an experimental model for neuronal differentiation and hypoxia-induced tumor cell dedifferentiation.

Neuroblastoma is a childhood tumor derived from precursor or immature cells of the sympathetic nervous system. Neuroblastomas show a tremendous clinical heterogeneity, encompassing truly benign as well as extremely aggressive forms. In vivo as well as in vitro data have shown that the degree of sympathetic neuronal tumor cell differentiation influences patient outcome. Unraveling mechanisms govern

Psychiatric nurses' view of nursing care, clinical supervision and individualised care : interventions on a dementia and on a general psychiatric ward

Popular Abstract in Swedish Psykiatriska vårdares erfarenheter av omvårdnad, grupphandledning och individuellt planerad omvårdnad på en avdelning för vård av gravt dementa personer och på en allmänpsykiatrisk avdelning. Avhandlingens övergripande syfte var att undersöka vårdarnas upplevelse av omvårdnadsarbetet samt betydelsen och effekterna av införandet av systematisk klinisk grupphandledning oThe aim of this thesis was to investigate nurses’ lived experience of daily nursing care and the impact and lived experiences of one years intervention with systematic clinical group supervision and supervised individually planned nur-sing care. This was carried out at an experimental ward (EW) (n=19) housing patients with dementia in comparison with a similar control ward (CW) (n=20) using a quas

Lysozyme-water interactions studied by sorption calorimetry

Hydration of hen egg white lysozyme was studied by using the method of sorption calorimetry at 25, 40, and 50degreesC. Desorption calorimetric measurements were performed at 25 and 40degreesC. The activity of water and partial molar enthalpy of mixing of water were determined as functions of water content. Hydration of lysozyme occurs in four steps: slow penetration of water into the protein-prote

Binary addressing technique with duty cycle control for LCDs

Introduction of duty cycle in the binary addressing technique is proposed to enable integration of liquid crystal display drivers with a digital system in a single chip. An analysis of this technique with duty-cycle control is presented. Effects of duty-cycle control on brightness uniformity of pixels in the liquid crystal display are discussed. A system on chip implementation of the technique is

Assay of type-specific M antigens on whole group A streptococci

A novel radioimmunoassay of type-specific M antigens on whole group A streptococcal cells is described. Absorbed rabbit anti-M antisera directed against M types 12 and 49 were used for determining M antigens on intact bacterial organisms. Staphylococcal protein A labelled with 125I was used as an anti-antibody reagent. The absorbed antisera were tested against ten homologous and 48 heterologous se

A VLSI architecture of the square root algorithm for V-BLAST detection

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

Estimating water content from electrical conductivity measurements with short time-domain reflectometry probes

Time domain reflectometry (TDR) is a widely used technique for measuring the dielectric constant (K-a) and bulk electrical conductivity (sigma(a)) of soil. The K-a measurement can be converted to water content (theta) by means of a (soil specific) calibration. Since the accuracy of the K-a measurement is dependent on the TDR probe length, probes longer than about 0.1 m are preferred. However, shor
