We analyse late summer phenology, abundance, and diversity of waders and waterfowl on a small gravel island, Kosa, on the western shore of Lake Baikal, eastern Siberia. We expected that the assemblages of waterbirds at such a small-scale, low quality roosting site would be characterised by lower species-diversity and numbers compared with high-quality staging sites like coastal mudflats. In compar

Clinical management of the prostate needs improved prognostic tests and treatment strategies. Because proteins are the ultimate effectors of most cellular reactions, are targets for drug actions and constitute potential biomarkers; a quantitative systemic overview of the proteome changes occurring during prostate cancer (PCa) initiation and progression can result in clinically relevant discoveries

Novel short-pulse X-ray sources, e.g., laser-produced plasmas, offer new approaches to the solution of the scatter-reduction problem in X-ray imaging, by the use of time-gated detection techniques. Monte Carlo simulations are used to estimate the scatter-reduction performance of time-gated imaging techniques within a range of X-ray energies, gating times and tissue parameters, Significant improvem

Radiative lifetimes for six highly excited levels in Fe II have been measured at Lund Laser Centre applying the laser induced fluorescence technique and two-step excitation. The energy levels belong to the even-parity 3d(6)(D-5)(4)d subconfiguration at about 10 eV. Branching fractions (BF:s) of 29 transitions from these levels to the 3d(6)(D-5)4p subconfiguration at about 5 eV have been measured i

During the last decade, software process simulation has been used to address a variety of management issues and questions. These include: understanding; training and learning; planning; control and operational management; strategic management; process improvement and technology adoption. This paper presents a simulation model that was developed to demonstrate the impact of unstable software requir

An improved clocking scheme and sharper circuit design and logic selection, which have yielded a five-to-tenfold increased in the speed of standard CMOS ICs, are discussed. The clocking strategy relies on a true single-phase clock, device sizes are varied to optimize their speed, and a precharged logic style reduces capacitive loads. The tradeoff is roughly a doubling of circuit area. The high-spe

In both chronic obstructive pulmonary disease (COPD) and multiple sclerosis (MS), combinations of environmental and genetic factors are likely to increase the vulnerability to acquire disease. This study was undertaken to investigate any possible comorbidity of COPD and MS, thus indicating common inflammatory vulnerability. Individuals with a diagnosis of COPD (including chronic bronchitis and emp

Aims and objectives. To explore the development over time of beliefs about health, illness and health care in migrant women with gestational diabetes mellitus born in the Middle East and living in Sweden and to study the influence on self-care and care seeking. Background. With today's extensive global migration, contact with the new society/health care confronts the migrant's culture of origin wi

BACKGROUND: The same mechanisms by which ultrasound enhances thrombolysis are described in connection with non-beneficial effects of ultrasound. The present safety study was therefore designed to explore effects of beneficial ultrasound characteristics on the infarcted and non-infarcted myocardium. METHODS: In an open chest porcine model (n = 17), myocardial infarction was induced by ligating a co

In December 2005, the WTO responded to the HIV/AIDS pharmaceutical crisis in the least developed world by voting to make the first permanent amendment to the WTO Agreements since their original negotiation during the Uruguay Round. New Article 31bis will amend the TRIPS Agreement to permit compulsory manufacturing licenses in order to facilitate supply of needed pharmaceuticals to those countries

Hippuric acid has been a major human metabolite for years. However, there is no well-known documented health benefit associated with it except for excretion of environmental-toxic exposures of aromatic compounds such as toluene, or from dietary protein degradation and re-synthesis by intestinal microflora metabolism of quinic acid via the shikimate pathway. Thus hippuric acid can appear in humans
