Cohomology of 3-dimensional color Lie algebras

We develop the cohomology theory of color Lie algebras due to Scheunert-Zhang in a framework of non-homogeneous quadratic Koszul algebras. In this approach, the Chevalley-Eilenberg complex of a color Lie algebra becomes a standard Koszul complex for its universal enveloping algebra, providing a constructive method for computation of cohomology. As an application, we compute cohomologies with trivi

Sticky Landscapes and Smooth Experiences: The Biopwer of Tourism Mobilities in the Öresund Region

As landscapes become ordered according to certain sets of economic, political, ecological or social practices and discourses, other possible orderings become limited in their potential. The article illustrates this with an example taken from the field of tourism and place marketing. The empirical focus is golf experiences in Scania, Sweden, bookable by individual consumers over the Internet. The o

The Stroop Strategy Test: Investigation of a computerised version of the Stroop Test for classifying Swedish military servicemen

A computerised test termed the Stroop Strategy Test, utilising the Stroop effect, is described. To assess the test's usefulness and discriminant power, it was given to three military groups adjudged on the basis of interview and a test of intelligence to differ in their qualifications (61 men of Level 1, 41 of Level 2, and 17 of Level 3, in descending order) and a group of 16 men imprisoned or put

Primary recovery of a genetically engineered Trichoderma reesei endoglucanase I (Cel 7B) fusion protein in cloud point extraction systems.

Here we present data to demonstrate how partitioning of a hydrophilic enzyme can be directed to the hydrophobic detergent-enriched phase of an aqueous two-phase system by addition of short stretches of amino acid residues to the protein molecule. The target enzyme was the industrially important endoglucanase I, EGI (endo-1,4-beta-D-glucan-4-glucanohydrolase, EC 3.2.1.4, Cel7B) of Trichoderma reese

TNF-alpha and IFN-gamma are overexpressed in the bone marrow of Fanconi anemia patients and TNF-alpha suppresses erythropoiesis in vitro

In Fanconi anemia (FA) C mice tumor necrosis factor alpha (TNF-alpha) and interferon gamma (IFN-gamma) have key roles in the pathogenesis of bone marrow failure. In FA subjects TNF-alpha was found to be increased in the serum and overproduced by patient-derived B-cell lines. In acquired aplastic anemia, a disease in which, similarly to FA, marrow failure occurs, TNF-alpha and IFN-gamma act as late

Expansion of the BioCyc collection of pathway/genome databases to 160 genomes

The BioCyc database collection is a set of 160 pathway/genome databases (PGDBs) for most eukaryotic and prokaryotic species whose genomes have been completely sequenced to date. Each PGDB in the BioCyc collection describes the genome and predicted metabolic network of a single organism, inferred from the MetaCyc database, which is a reference source on metabolic pathways from multiple organisms. I

Pre-penetration events in fungal parasitism of nematode eggs

The present investigation deals with the main factors involved in early infection of nematode eggs by fungal parasites. We studied the effect of hydrophobicity on appressorium formation by germlings of Pochonia rubescens (syn. Verticillium suchlasporium), P. chlamydosporia (syn. V. chlamydosporium) and Lecanicillium lecanii (syn. V. lecanii). Appressoria were frequently formed on hydrophobic surfa

Proteinase 3 and CD177 are expressed on the plasma membrane of the same subset of neutrophils.

Proteinase 3 (PR3) is found in granules of all nentrophils but also on the plasma membrane of a subset of nentrophils (mPR3). CD177, another neutrophil protein, also displays a bimodal surface expression. In this study, we have investigated the coexpression of these two molecules, as well as the effect of cell activation on their surface expression. We can show that CD177 is expressed on the same

Social capital, the miniaturisation of community, traditionalism and first time acute myocardial infarction: A prospective cohort study in southern Sweden.

This longitudinal study investigates the impact of social participation, trust and the combinations of social participation and trust on the incidence of first time acute myocardial infarction (AMI) in the population of Scania, southern Sweden. It is based on the cross-sectional 2000 public-health survey in Scania with a 59% participation rate and 13,604 participants, and prospective morbidity/mor

Metaplastic columnar mucosa in the cervical esophagus after esophagectomy.

OBJECTIVE: To evaluate the pathogenesis of metaplastic processes within the esophagus using a human model in which the exact duration of reflux was known. SUMMARY BACKGROUND DATA: The pathogenesis of Barrett's esophagus (BE) is incompletely understood. Patients undergoing esophagectomy and gastric tube reconstruction represent a good model for studying the pathophysiology of columnar cell metaplas

The conodont fauna in the middle ordovician Eoplacognathus pseudoplanus Zone of Baltoscandia

Conodont faunas from the Eoplacognathus pseudoplanus Zone in five main areas of Middle Ordovician rocks in Sweden are described and discussed and compared with faunas of comparable age from neighbouring areas. The investigation is based on 118 samples which together yielded 175 114 conodont elements. The Swedish conodont faunas are intermediate between shallower-water faunas from the eastern part

All-diode-laser ultraviolet absorption spectroscopy for sulfur dioxide detection

Ultraviolet radiation around 302 nm was produced by sum-frequency generation in beta-barium borate employing a blue and a near-infrared diode laser. The diode-laser-based spectrometer has a mode-hop-free tuning range of 50 GHz and was used for high-resolution spectroscopic detection of sulfur dioxide. Differential measurements of several gas concentrations, at low pressure as well as at ambient at

A new concept for large deformable mirrors for extremely large telescopes

For extremely large telescopes, there is strong need for thin deformable mirrors in the 3-4 m class. So far, feasibility of such mirrors has not been demonstrated. Extrapolation from existing techniques suggests that the mirrors could be highly expensive. We give a progress report on a study of an approach for construction of large deformable mirrors with a moderate cost. We have developed low-cos

Insulin secretion and insulin sensitivity in relation to fasting glucose in healthy subjects.

OBJECTIVE - This study evaluated insulin secretion and insulin sensitivity in healthy subjects with normal fasting glucose. RESEARCH DESIGN AND METHODS - A total of 148 healthy women (aged 53-70 years) underwent a glucose-dependent arginine stimulation test and a 2-h euglycemic-hyperinsulinemic clamp. In the arginine test, arginine (5 g) was injected intravenously under baseline (fasting) conditio

Exploring climatic and biotic controls on Holocene vegetation change in Fennoscandia

# 1. We investigated the potential drivers of Holocene vegetation changes recorded at four Scandinavian pollen sites, two in Sweden and two in Finland, at a time when they were largely free of anthropogenic influence. # 2. We used the generalized dynamic vegetation model LPJ-GUESS forced with climate anomaly output from an atmospheric general circulation model to simulate tree species dynamics

Where is the central terminal located? In search of understanding the use of the Wilson central terminal for production of 9 of the standard 12 electrocardiogram leads

The aim of this study was to evaluate the understanding of the term central terminal (CT) and to consider the consequences of this level of understanding. A total of 150 questionnaires was distributed during the 30th International Congress of Electrocardiology 2003, Helsinki, Finland; 42 (28%) of the anonymous questionnaires returned were considered adequate for the purpose of this study. The ques
