The objective of this article is to amalgamate previous results into a speculative synthesis that sheds light on the causes of secondary brain damage following either global/forebrain or focal ischemia. The hypothesis is based on the well-founded assumption that the pathophysiology of the brain damage incurred by global or forebrain ischemia is different from that of focal ischemia. In the former,

Nya forskningsresultat vänder upp och ner på uppfattningen om hur kol inlagras i skogsmark. Det så kallade humuslagret i skogsmarken verkar byggas upp underifrån istället för ovanifrån. Det kan vara avgörande för att bättre kunna beskriva kolets kretslopp i ekosystemmodeller och i förlängningen göra bättre prediktioner i globala klimatmodeller.

In May 2004 Turkey became a party to the United Nations Framework Convention on Climate Change. In February 2009, in a time when the Protocol’s first commitment period comes to an end, Turkey also became a party to the Kyoto Protocol. The aim of this article is twofold: first, to identify the diverse factors that lie behind Turkey’s late ratification of the Kyoto Protocol, and second, to discuss i

Visual cues provide an important means for aerial creatures to ascertain their self-motion through the environment. In many insects, including flies, moths, and bees, wide-field motion-sensitive neurons in the third optic ganglion are thought to underlie such motion encoding; however, these neurons can only respond robustly over limited speed ranges. The task is more complicated for some species o

The degree of trophic specialization determines the ability of predators to cope with changing foraging conditions, but in predators that prey on hundreds of species it is challenging to assess, especially when prey identity varies among predator individuals and across space and time. Here, we test the hypothesis that a bat species foraging on flying insects like moths will show ample flexibility

Incubation experiments are the most common approach to measure methane (CH 4 ) oxidation potential in soils from various ecosystems and land-use practices. However, the commonly used headspace CH 4 injection into microcosms and the shaking of the soil slurry during incubation fully removes CH 4 (soil-born) and O 2 (air-born) gradients common in situ, and may also induce various errors and disturb

Time-varying spatially-coupled low-density parity-check convolutional codes (SC-LDPC-CCs) exhibit excellent features, but their representation requires a very large number of parameters. On the other hand, the description of time-invariant SC-LDPC-CCs is very convenient and their error rate performance, though usually worse, is often satisfactory. In this paper we investigate the girth properties

The field of microbial ecology has been developing rapidly, largely owing to the introduction of new molecular methods for identifying individuals, species and populations of microorganisms in nature. In contrast to traditional methods, the new ones do not require the isolation and culture of organisms from the environment. With many of the new methods, genotypes and species of microorganisms can

Several studies have indicated that the capture of nematodes by the nematophagous fungus Arthrobotrys oligospora is mediated by a lectin on the fungal surface. One of the major surface proteins of this fungus showed haemagglutinating activity and was isolated by affinity chromatography using a mucin Sepharose column. Biochemical analysis showed that the protein was a dimeric glycoprotein with a mo

I kolonin Danska Västindien utnjyttades förslavade kvinnor inte bara som arbetskraft, de uttnyttjades också sexuellt. Möjligheterna till motstånd var så gott som obefinntliga. Ändå kämpade slavkvinnor för rätten till att bestämma över egen kropp.
