In this paper we present new relative sea-level data from southern Greenland, a key area for understanding the Greenland Ice Sheet (GIS) response to climate change. Within fourteen lakes and marine lagoons from the inner part of Bredefjord (Nordre Sermilik) in southern Greenland, isolations revealed by stratigraphic and palaeoecological analyses are dated and relative sea levels reconstructed. Due
The use of celestial or geomagnetic orientation cues can lead migratory birds along different migration routes during the migratory journeys, e.g. great circle routes (approximate), geographic or magnetic loxodromes. Orientation cage experiments have indicated that migrating birds are capable of detecting magnetic compass information at high northern latitudes even at very steep angles of inclinat
The objective of present work was to determine and compare the components of bioaerosol in several sectors of plant processing industries. The Study was conducted in 10 Facilities engaged in herb and grain processing, flax threshing, grain storing, baking, and cereals production. The air samples were taken on glass fibre litters with an AS-50 sampler. We determined the concentrations of airborne m
During migratory endurance flights, which are energetically very demanding, migrants have to deal with prolonged elevated generation of reactive oxygen species (ROS). To limit the damaging actions that ROS have on lipids and proteins, migrating birds are known to upregulate their antioxidant defence system. However, there may be additional ways to limit oxidative damage incurred from flying. Migra
Extracellular matrix remodeling mechanisms are understudied in cardiac development and congenital heart defects. We show that matrix-degrading metalloproteases ADAMTS1 and ADAMTS5, are extensively co-expressed during mouse cardiac development. The mouse mutants of each gene have mild cardiac anomalies, however, their combined genetic inactivation to elicit cooperative roles is precluded by tight g
The fate of soil organic matter (OM) is determined by its microbial use for growth or respiration. Many environmental factors influence microbial OM use, including the presence of contaminants and toxins in the environment, such as heavy metals. We evaluated short- and long-term responses of microbial processes to metal contamination by estimating biomass concentrations and growth rates of bacteri
Older people make up an increasing proportion of the homeless population and their homelessness is often combined with problems such as substance use, mental illness and physical problems. While much research has focused on short-term shelters, food and clothing, less is known about arrangement providing permanent supportive housing where older homeless adults can stay the rest of their lives.

Quantifying the water exchange between a forest stand and the atmosphere is of major interest for the prediction of future growth conditions and the planning of silvicultural treatments. In the present study, we address (i) the uncertainties of sap flow estimations at the tree level and (ii) the performance of the simulation of stand transpiration. Terrestrial laser scan images (TLS) of a mature b
Popular Abstract in Swedish Andningsvägarna kan schematiskt uppdelas i en övre och nedre del där den övre består av näsa, bihålor, (mellanöra) och struphuvud och den nedre av luftstrupe, luftrör samt alveoler. Sjukdomar i andningsvägarna, såsom astma och olika allergiska tillstånd, är vanligt förekommande, men mekanismerna bakom deras uppkomst och utveckling är ofullständigt klarlagda. NeuropeptidThe investigations focus on the neuropeptidepituitary adenylate cyclase-activating peptide and its effects on airway regulation, with emphasis on smooth muscle relaxation and neutrophil activation and migration. In the nasal mucosa, PACAP-containing nerve fibers were localized invascular smooth muscle and close to seromucous glands. In the lung, PACAP-containing nerve fibers were found close to se
The nineteenth century’s long term planning and successive construction of new burial grounds and new ways of burial, with the help of among others scientific, technical and ideological strategies, have been quite successful in institutionalising a consciousness of what a proper place of death should be like. For the architect Augustus Welby Pugin the promotion of a revival of the Gothic style in
Testing ofIntegrated Circuits is important to ensure the production offault-free chips. However, testing is becoming cumbersome andexpensive due to the increasing complexity of these ICs. Technologydevelopment has made it possible to produce chips where a completesystem, with an enormous transistor count, operating at a highclock frequency, is placed on a single die - SOC (System-on-Chip).The devi
It has been generally accepted that residual cartilage and subchondral bone has to be removed in order to get bony fusion in arthrodeses. In 1998 we reported successful fusion of 11 rheumatoid ankles, all treated with percutaneous fixation only. In at least one of these ankle joints there was cartilage left. More than 25 rheumatoid patients with functional alignment in the ankle joint have subsequ
Popular Abstract in Swedish TNF (Tumor Necrosis Factor eller Tumör-Nekrotisk-Faktor) är en molekyl som utsöndras av kroppens makrofager (latin för storätare) när dessa kommer i kontakt med bakterier. Det TNF som bildas aktiverar andra celler, särskilt vita blodkroppar och de celler som täcker blodkärlsväggens yta (endotelceller). Syftet med detta är att aktivera kroppens immunförsvar och döda baktTNF (Tumor Necrosis Factor) is a pro-inflammatory cytokine which binds to two cell surface receptors, TNF-R55 and TNF-R75. The receptors undergo proteolytic cleavage and release a fragment (soluble TNF-receptors or TNF-Binding Protein), TNF-R55-BP and TNF-R75-BP. Soluble TNF-receptors are able to bind and inactivate TNF. The release of soluble TNF-receptors was measured with ELISA. TNF binding cap
