Harmonic morphisms from the classical non-compact semisimple Lie groups

We construct the first known complex-valued harmonic morphisms from the non-compact Lie groups View the MathML source, SU*(2n) and View the MathML source equipped with their standard Riemannian metrics. We then introduce the notion of a bi-eigenfamily and employ this to construct the first known solutions on the non-compact Riemannian SO*(2n), SO(p,q), SU(p,q) and Sp(p,q). Applying a duality princ

Innovation processes and proximity: The case of IDEON firms in Lund, Sweden

Increasing pressure on innovativeness and collaboration is supposed to strengthen the importance of geographical proximity in innovation systems. But simultaneously there are;globalization forces' and information and communication technology (ICT) developments that stress wider contexts and different dependencies to place and distance. With case studies of innovative firms at IDEON Science Park in

Masculinity and Punishment: Men's Upbringing of Boys in Rural Vietnam

This article examines men's use of physical punishment when interacting with their sons or grandsons in rural Vietnam. By drawing on two periods of anthropological fieldwork in a northern Vietnamese commune, the article analyses the ways in which violence is informed by, while also perpetually reinforcing, a masculine discourse. Vietnam has ratified the Convention on the Rights of the Child and in

Non-viable cervico-isthmic pregnancy: the importance of an accurate sonographic diagnosis to preserve fertility

BACKGROUND: Cervico-isthmic pregnancy is a rare occurrence and until the use of current ultrasonographic techniques was associated with a disastrous outcome for women desiring to maintain their fertility. CASE REPORT: A 39-year-old woman was diagnosed at 12 weeks of amenorrhoea with an intra-uterine non-viable pregnancy and a low implantation of the gestational sac. Medical management of this situ

Ucon-benzoyl dextran aqueous two-phase systems: protein purification with phase component recycling

Benzoyl dextran with a degree of substitution of 0.18 was synthesized by reacting dextran T500 with benzoyl chloride. A new type of aqueous two-phase system composed of benzoyl dextran as bottom phase polymer and the random copolymer of ethylene oxide and propylene oxide (Ucon 50-HB-5100) as top phase polymer has been formed. The phase diagram for the system Ucon 50-HB-5100-benzoyl dextran with a

Monitoring of atherosclerosis

Population-based epidemiological studies of atherosclerosis using autopsy material is now impossible to perform in most countries due to declining autopsy rates. Based on epidemiological studies of atherosclerosis using autopsy material in five European cities which were carried out with an interval of 25 years in the 1960s and 1980s, respectively, we have shown that atherosclerosis in young so-ca

A(1) receptor deficiency causes increased insulin and glucagon secretion in mice

Adenosine influences metabolism and the adenosine receptor antagonist caffeine decreases the risk of type 2 diabetes. In this study the metabolic role of one adenosine receptor subtype, the adenosine A(1)R, was evaluated in mice lacking this receptor [A(1)R (-/-)]. The HbA1c levels and body weight were not significantly different between wild type [A(1)R (+/+)] and A(1)R (-/-) mice (3-4 months) fe

Analytical Model Study of Dendrimer/DNA Complexes.

The interaction between positively charged poly(amido amine) (PAMAM) dendrimers of generation 4 and DNA has been investigated for two DNA lengths; 2000 basepairs (bp; L = 680 nm) and 4331 bp (L = 1472.5 nm) using a theoretical model by Schiessel for a semiflexible polyelectrolyte and hard spheres. The model was modified to take into account that the dendrimers are to be regarded as soft spheres, t

Environmental effects of ozone depletion and its interaction with climate change: Progress report 2007

This year theMontreal Protocol celebrates its 20th Anniversary. In September 1987, 24 countries signed the ‘Montreal Protocol on Substances that Deplete the Ozone Layer’. Today 191 countries have signed and have met strict commitments on phasing out of ozone depleting substances with the result that a 95% reduction of these substances has been achieved. The Montreal Protocol has also contributed t

Holocene palaeoecology along the Blekinge coast, SE Sweden, and implications for climate and sea-level changes

To investigate the Holocene vegetation history and shoreline displacement along the southeastern Swedish coast, two radiocarbon dated pollen, macrofossil and mineral magnetic sequences were studied in the western Blekinge coast: Hunnemara Lake and Smygen Bay. Both pollen records show mosaic vegetation with grasslands, heaths and woodlands prior to 11 300 cal. BP. Pinus-dominated mixed forest was i

Cross-Language Differential Item Functioning of the Job Content Questionnaire Among European Countries: The JACE Study

Little is known about cross-language measurement equivalence of the job content questionnaire (JCQ) The purposes of this study were to assess the extent of cross-language differential item functioning (DIF) of the 27 JCQ items in six languages (French, Dutch, Belgian-French, Belgian-Dutch (Flemish), Italian, and Swedish) from six European research centers and to test whether its effects on the sca

Rare earth elements in forest-floor herbs as related to soil conditions and mineral nutrition

Mixtures of rare earth elements (REEs) in fertilizers are widely used in Chinese agriculture to improve crop nutrition. REE concentrations in wild-growing plants, especially herbs, are little known. This study describes differences in the concentrations and proportions of REEs in eight forest-floor herbaceous plants and relates these differences to soil and mineral nutrient conditions. REEs studie

Experimental evaluation of small diameter synthetic arterial grafts

Platelets labelled with Indium-111 were used to examine the in vivo thrombogenicity of different vascular grafts. The deposition of platelets in two partly different kinds of umbilical vein grafts, double velour Dacron grafts and double velour Dacron grafts with internal collagen was studied as a function of time. The grafts were inserted end to side in the femoral artery of pigs and then imaged f

A simple spectrophotometric method based on pH-indications for monitoring partial and total alkalinity in anaerobic processes

Partial alkalinity, as a measure of bicarbonate concentration, and total alkalinity, as a measure of the concentration of bicarbonate and volatile fatty acids, are useful parameters for monitoring anaerobic digestion processes. This paper reports a new method based on pH-indicators and spectrophotometric measurements for the monitoring of partial and total alkalinity. The method was used in an off

Cytogenetic Analysis of 101 Giant Cell Tumors of Bone: Nonrandom Patterns of Telomeric Associations and Other Structural Aberrations

Giant cell tumor of bone (GCTB) is a benign but locally aggressive tumor with metastatic potential. We performed cytogenetic analysis on 10 1 GCTB from 92 patients. Karyotypes were obtained from 95 tumors, 47 of which had clonal aberrations. The majority of the cytogenetically abnormal GCTB had multiple, up to 28 per tumor, clones. Clonal telomeric associations (tas) and other structural and numer

Cost-effectiveness of primary cytology and HPV DNA cervical screening

Because cost-effectiveness of different cervical cytology screening strategies with and without human papillomavirus (HPV) DNA testing is unclear, we used a Markov model to estimate life expectancy and health care cost per woman during the remaining lifetime for 4 screening strategies: (i) cervical cytology screening at age 32, 35, 38, 41, 44, 47, 50, 55 and 60, (ii) same strategy with addition of
