Tidal marshes have recently been shown to be important biogenic Si recycling surfaces at the land-sea interface. The role of vegetation in this recycling process has not yet been quantified. In situ and ex situ decomposition experiments were conducted with Phragmites australis stems. In a freshwater tidal marsh, litterbags were incubated at different elevations and during both winter and summer. B

The radioactive decay of 238U and 232Th has recently been used to determine ages for some of the oldest stars in the Universe. This has highlighted the need for accurate observational constraints on production models for the heaviest r-process elements which might serve as stable references, notably osmium and iridium. In order to provide a firmer basis for the observed abundances, we have perform

This essay is an inquiry into manorial production in Scania. Its growth was dependent on the long-term development of European grain prices. When prices increased landlords were encouraged to put more land under the plough. The estates' main income came, to an increasing extent, from demesne production, which finally dominated the income profile. The peasants' most important contribution to the la

When mourning pets, costoms and rituals are in many ways similar to what is used for humans. Whether one likes it or not, the market for pets, dead or alive is an expanding and lucrative one.

Faunistic data on fungus gnats from the county of Møre og Romsdal in Norway are presented and all species known from the county are summarized in a checklist. Treatment of some 23000 specimens, collected with one Malaise trap and one window trap for a whole year each, resulted in the identifi cation of 315 species from a single site at Jordalsgrend, Sunndal municipality. Material from three other

The aim of this study was to analyse whether the interleukin-1 (IL-1) and IL-6 gene polymorphisms were associated with the susceptibility of chronic periodontitis. Genomic DNA was obtained from 20 patients with chronic periodontitis and 31 periodontally healthy subjects. All subjects were of North European heritage. The test subjects were kept in a maintenance program after periodontal treatment b

InledningDet är kväll den 15:e januari 2004. Idag var det den andra dagen i Mijailovic-rättegången i Stockholms tingsrätt. Mijailovic försvarar sig, men inte genom att svara på frågor. Han representerar det moderna. Hans psykos, säger han, fick honom att få panik, höra röster och döda en utrikesminister. Om han fått träffa en läkare skulle allt varit annorlunda. Sedan början av 1800-talet har dett

Bacteriuria is associated with acute disease conditions of varying severity.48 and 62 Consequently, the definition of bacterial virulence for the urinary tract depends on the end-point chosen. Acute pyelonephritis is characterized by fever, flank pain, and general malaise. Laboratory findings include pyuria (leukocytes in the urine), elevated acute phase reactants in serum (C reactive protein [CRP

Transmitted-reference (TR) schemes for time-hopping impulse radio (TH-IR) ultra-wideband (UWB) communications allow the use of simple receiver structures that are able to combine energy from different multipath components without channel estimation. A conventional TR receiver consists of a simple delay-and-multiply operation combined with an integrator. On the downside, it shows a performance loss

The well-known integral pulse frequency modulation (IPFM) model is used to generate the occurrence times of normal sinus rhythm. In a previous study, we extended the model to account for ectopic beats and subsequent variation in sinus rhythm that may accompany an ectopic beat; a phenomenon known as heart rate turbulence (HRT). Inspired by the extended model, a new approach to characterize HRT was

The leakage characteristics of a novel claw-pole electrically magnetized synchronous machine are discussed in this paper. The novelty of the machine is that the magnetizing coils are placed in magnetically conducting end-plates, thus eliminating the need of slip-rings in the rotor. A previous study comparing this machine with a permanent magnet alternative showed a 20% higher leakage in the electr
