The oxides that form during thermal oxidation of natural FeS2 (pyrite and marcasite) consist of nanometer-sized crystals of alpha-Fe2O3 and gamma-Fe2O3. This is shown with heating experiments that were made up to 650 degrees C, which resembles temperatures used in metallurgical processes. It is shown that magnetic measurements can play a key role in the investigation of this reaction, due to the u

Rat bladder hypertrophy, induced by a partial ligation of the urethra, was used to study the accompanying changes of microvascular smooth muscle mechanics, pharmacology and morphology. A segment of a microarterial vessel to the bladder was taken from a defined anatomical location and studied in a wire myograph in vitro at the length for maximal isometric force development (Lmax). After 10 days of

The excitation-decay processes at the F 1s photoabsorption edge in LiF crystal are studied using resonant inelastic x-ray scattering spectroscopy. The Raman-type linear dispersion and the narrowing of the x-ray fluorescence peak are observed at resonant excitation. A theoretical model based on the Kramers-Heisenberg formula describes well the main features in fluorescence spectra and allows one to

Gentrification is a current and often debated concept that concerns social changes in our cities. The concept relates to a development whereby areas earlier inhabited by less wealthy social groups are taken over by middle and upper middle-class residents. In the discussions of these changes, two perspectives have dominated. Representatives for the consumer perspective argue that gentrification occ

A concept based on the Peroxidase-chip (P-chip), antibody co-immobilization, competitive and enzyme-channeling principle was exploited to develop an integrated flow-through amperometric biosensor for detection of environmental pollutants such as s-triazine herbicides. In this concept, recombinant peroxidase is immobilized on the gold electrode (P-chip) in such a way that direct electron transfer i

PURPOSE. To study the possible involvement of the rod (SLC24A1) and cone (SLC24A2) Na-Ca+K exchanger (NCKX) genes in retinal diseases. METHODS. DNA was collected from unrelated patients with retinal disease, mainly from North America. A human genomic library was screened with the cone NCKX cDNA, and hybridizing clones were sequenced to determine the genomic organization of the SLC24A2 gene. The si

For a cathode duct of a proton-exchange membrane fuel cell, a three-dimensional analysis method is further developed to include two-phase, multicomponent gas and heat transport processes. A set of momentum, heat transport, and gas species equations is solved for the whole duct by coupled source terms and variable thermophysical properties. The effects of the electrochemical reactions on the heat g

Diabetic cardiovascular autonomic neuropathy increases the risk of deterioration in renal function and is associated with increased mortality in patients with renal failure. Type 1 diabetic patients with long diabetes duration, matched for age (38 +/- 9 years) and diabetes duration (28 +/- 8 years) were studied regarding the association between cardiovascular autonomic nerve function and different

Popular Abstract in Swedish Vad har den slaviskt inspirerade östersjökeramiken som arkeologer finner i Skandinavien med slaver att göra? Levde de som gäster i huset? Vikingen och hanseaten har sedan länge sina platser inbokade på den historiska scenen. Under äldre medeltid rörde sig även andra aktörer över Östersjöns vatten. Främmande gäster besökte och bosatte sig i Skandinavien. Bland dem fanns Scholarly texts on Slavic-Scandinavian relations have concentrated on two main areas of interest. During the Viking Age the economic and social contacts between the lake Mälaren district and Rus’ were extensive. However, at the beginning of the Middle Ages, political antagonism between the two expanding realms of the Svear and the Novgorodians is noticeable. In southern Scandinavia, the hostility

The brain lesions in spontaneously hypertensive stroke-prone rats (SHRSP) are characterised by multifocal microvascular damage, breakdown of the blood-brain barrier, massive extravasation of plasma constituents and severe brain oedema, with consequent spongy and cystic tissue destruction in the cerebral cortex and basal ganglia as well as loosening of the white matter. In this paper we analyse in

This report is the first part of the project Use of industrial by-products and filler in concrete - long term properties/durability. The aim is to improve the knowledge of long term properties/durability of cement and concrete produced using industrial by-products/fillers in order to promote an efficient, safe, reliable and increased use of such types of materials. The results presented in the rep

Popular Abstract in Swedish Kroniskt Obstruktiv Lungsjukdom (KOL) är idag världens fjärde vanligaste dödsorsak vars dödlighetsfrekvens ökar. KOL är en lungsjukdom som nästan alltid beror på rökning och i hela världen är cirka 600 miljoner människor drabbade av sjukdomen. Detta gör KOL till världens vanligaste kroniska sjukdom. I Sverige beräknas sjukvårdskostnaderna för KOL att uppgå till ca 9,1 mProteomic analysis of bronchoalveolar lavage (BAL) fluid from smokers at risk of developing chronic obstructive pulmonary disease (COPD) and never smokers is described. COPD is currently the world's fourth leading cause of death and its prevalence is increasing. The leading cause of COPD is smoking and an estimated 600 million people in the world suffer from COPD which makes it the world's most co

Model systems have shown that adenoviral vector mediated transient gene expression can potentially be applied for the treatment of brain tumours, neurodegenerative diseases and brain injuries. Most studies utilized adenovirus serotype 5 (Ad5) based vectors, which as adhesion molecules require the coxsackie adenovirus receptor (CAR) as a critical determinant for cellular infection. In this report,

Extravasated endogenous serum albumin and fibrinogen were identified immunohistochemically in coronal brain sections from normotensive Wistar Kyoto (WKY) rats and spontaneously hypertensive rats (SHR) after permanent ligation of the right middle cerebral artery. Infarcts were seen in all the SHR but only in 6 out of 14 WKY. Six hours after ligation, extravasated proteins were located primarily wit
