Remote monitoring of industrial emissions by combination of lidar and plume velocity measurements

We describe a new method for gas flux measurements that is a combination of differential absorption lidar (DIAL) and wind videography. The wind speed was measured by an imaging method that calculates the horizontal displacement of the plume with cross-correlation techniques. High spatial and temporal resolution is achieved with histogram equalization and window-filtering techniques. Simultaneous m

Geographic Origin as a Determinant of Carotid Artery Intima-Media Thickness and Brachial Artery Flow-Mediated Dilation. The Cardiovascular Risk in Young Finns Study.

Objective - People living in eastern Finland have approximate to 40% higher coronary heart disease mortality rates than western Finns. Whether this is because of genetic or environmental factors is unknown. We examined the effect of geographic family origin on subclinical atherosclerosis among young Finns. Methods and Results - As part of a longitudinal follow-up study, we measured carotid intima-

Adsorption and aggregation of cationic amphiphilic polyelectrolytes on silica

The adsorption of two cationic amphiphilic polyelectrolytes, which are copolymers of two charged monomers, triethyl(vinylbenzyl)ammonium chloride and dimethyldodecyl(vinylbenzyl)ammonium chloride (which is the amphiphilic one) with different contents of amphiphilic groups (40% (40DT) and 80% (80DT)), onto the hydrophilic silica-aqueous solution interface has been studied by in situ null ellipsomet

A 6-year follow-up of dosing, coagulation factor levels and bleedings in relation to joint status in the prophylactic treatment of haemophilia

The primary aim of this study was to investigate the possible relationship between coagulation factor level and bleeding frequency during prophylactic treatment of haemophilia after stratification of the patients according to joint scores. The secondary aim was to obtain a systematic overview of the doses of coagulation factors prescribed for prophylaxis at the Malmo haemophilia treatment centre d

Up-regulation of glucocorticoid-regulated genes in a mouse model of Rett syndrome

Rett syndrome (RTT) is a severe form of mental retardation, which is caused by spontaneous mutations in the X-linked gene MECP2. How the loss of MeCP2 function leads to RTT is currently unknown. Mice lacking the Mecp2 gene initially show normal postnatal development but later acquire neurological phenotypes, including heightened anxiety, that resemble RTT. The MECP2 gene encodes a methyl-CpG-bindi

Peripheral vestibular disorders with acute onset of vertigo.

Disorders of the vestibular nerve and end organs are the most common causes of vertigo. The advances in recognizing different forms of canalolithiasis and cupulolithiasis, which sometimes present with continuous positional nystagmus, have revealed a peripheral vestibular aetiology in which central nervous system lesions were previously suspected. Treatments using repositioning manoeuvres are also

Near- and Deep-Ultraviolet Resonance Raman Spectroscopy of Pyrazine-Al-4 Complex and Al-3-Pyrazine-Al-3 Junction

Near- and deep-ultraviolet (UV) resonance Raman spectroscopy of pyrazine-Al-4 complex and Al-3-pyrazine-Al-3 junction was investigated theoretically with a quantum chemical method. Here, 325 and 244 nm were employed as near- and deep-UV sources in our theoretical study The intensities of static normal Raman spectra of pyrazine-Al-4 complex and Al-3-pyrazine-Al-3 junction were enhanced oil the orde

Homoclinic and Heteroclinic Bifurcations Close to a Twisted Heteroclinic Cycle

We study the interaction of a transcritical (or saddle-node) bifurcation with a codimension-0/codimension-2 heteroclinic cycle close to (but away from) the local bifurcation point. The study is motivated by numerical observations on the traveling wave ODE of a reaction–diffusion equation. The manifold organization is such that two branches of homoclinic orbits to each fixed point are created when

MHC, health, color, and reproductive success in sand lizards

Good genes" are genetic elements that contribute to lifetime reproductive success, regardless of an individual's additional genotype. Their existence is debated, and most work has targeted their viability benefits to the offspring of choosy females. In the present study, we analyze a case of potential good genes effects in adult male sand lizards ( Lacerta agilis). We show that males with a partic

A comparison of single and multiphase jets in a crossflow using large eddy simulations

Large eddy simulations (LES) are performed for single and multiphase jets in crossflow (JICF). The multiphase JICF are compared to the single-phase case for the same momentum and mass flow, ratios but with droplets of different sizes. Multiphase JICF have stronger counterrotating vortex pairs (CVPs) than a corresponding single-phase JICF. Moreover their trajectories are higher and their induced wa

Biallelic inactivation of TP53 rarely contributes to the development of malignant peripheral nerve sheath tumors

About 10% of the patients with neurofibromatosis type 1 (NF1) develop malignant peripheral nerve sheath tumors (MPNSTs), accounting for half of all MPNST cases. Several nonrandom chromosomal aberrations have been found, but the target genes remain mostly unrecognized. Mutations in the NF1 and TP53 genes have been found in some MPNSTs, and recent data from mouse models support a synergistic effect

The influence of ageing and exercise on tendon growth and degeneration - hypotheses for the initiation and prevention of strain-induced tendinopathies

Strain-induced tendinopathy is a common injury in both human and equine athletes, with increasing incidence associated with greater involvement in sport and an increasingly aged population. This paper reviews our studies on the abundant non-collagenous protein, cartilage oligomeric matrix protein (COMP), in equine tendons. Its variation between tendon type and site, age and exercise has provided a

Enhanced rate of cleavage at Arg306 and Arg506 in coagulation factor Va by Gla domain-mutated human activated protein C.

A Gla domain-mutated protein C variant, QGNSEDY, modified at positions 10-12, 23, 32-33, and 44, having enhanced affinity for negatively charged phospholipid and increased anticoagulant potential, was used to elucidate the importance of the interaction between the Gla domain and the phospholipid for the ability of activated protein C (APC) to inactivate factor Va (FVa). FVa degradation by wild typ

Colour and image texture analysis in classification of commercial potato chips

The images of commercial potato chips were evaluated for various colour and textural features to characterize and classify the appearance and to model the quality preferences of a group of consumers. Features derived from the image texture contained better information than colour features to discriminate both the quality categories of chips and consumers' preferences. Entropy of a* and V and energ

Funktionshindrad - med rätt till arbete? En komparativ studie av arbetsrättsliga regleringar kring arbete och funktionshinder i Sverige, England och Tyskland.

Popular Abstract in Swedish Arbete är centralt i det moderna samhället. Samtidigt står många människor av olika anledningar utanför den ordinarie arbetsmarknaden. Att detta i särskild utsträckning gäller personer med funktionshinder har i många länder fått till följd att lagstiftning antagits för att på olika sätt öka arbetskraftsdeltagandet för denna grupp. De bestämmelser som reglerar arbete ochThis doctoral thesis examines labour market legislation on disability and work in Sweden, England and Germany. In order to provide increased access to the labour market for people with disabilities all three studies countries have undertaken more of less far-reaching legislative measures over a number of decades, both in line with, or as a result of, general labour and employment legislation, but

Influence of mannan epitopes in glycoproteins - Concanavalin A interaction. Comparison of natural and synthetic glycosylated proteins

Two natural glycoproteins/glycoenzymes, invertase and glucoamylase, and two neoglycoconjugates, synthetized from Saccharomyces cerevisiae mannan, bovine serum albumin and penicillin G acylase were tested for interaction with lectin Concanavalin A (Con A). The interaction of natural and synthetic glycoproteins with Con A was studied using three different experimental methods: (i) quantitative preci

On the numerical evaluation of stress intensity factors for an interface crack of a general shape

A numerical algorithm is presented for the problem of a crack along the interface of an elastic inclusion embedded in an elastic plane subjected to uniform stress at infinity. The algorithm is based on a Fredholm integral equation of the second kind and allows for fast and accurate solutions to geometries of great complexity. In an example crack opening displacement and stress intensity factors ar

Potential denitrification in wetland sediments with different plant species detritus

The effect of detritus originating from different plant species on denitrifying capacity was investigated in a Swedish wastewater treatment wetland. Intact sediment cores containing sediment with a detritus layer were collected from wetland basins dominated by Typha latifolia, Phragmites australis, or Elodea canadensis in November 2000 and potential denitrification was measured using the acetylene
