If individuals occupy habitats in a way that maximizes their fitness, if they are free to occupy the habitats they choose and if fitness declines with population density, then their abundance across habitats should follow an ideal free distribution. But, if individuals are genetically related, this simple fitness-maximization mechanism breaks down. Habitat occupation should obey Hamiltons rule (na
Observations of the ultra-sharp-lined HgMn star chi Lupi made with the Goddard High Resolution Spectrograph after the Hubble Space Telescope First Servicing Mission display the effect of COSTAR corrective optics upon the spectral resolution of several observing modes. The resolution is restored to levels expected in the absence of the telescope spherical aberration for all observations made throug
In a large variety of disciplines, fundamental studies often straddle in self-referential situations, in need of relativization to language and complementaristic resolution. In such attempts, the languages at play are hardly visible themselves. Only shadows of language, somewhat characteristic of the various disciplines, become visible and tractable. We select two domains, quantum mechanics and cy
Intramuscular triacylglycerol is an important energy store and is also related to insulin resistance. The mobilization of fatty acids from this pool is probably regulated by hormone-sensitive lipase (HSL), which has recently been shown to exist in muscle and to be activated by both adrenaline and contractions. Adrenaline acts via cAMP-dependent protein kinase (PKA). The signalling mediating the ef
PURPOSE: To determine the normal values of the anterior and posterior capsular distances of the hip joint in healthy children by means of US, using MR imaging as reference, and to evaluate any possible correlation between age, length, weight and anterior capsular distance (ACD). MATERIAL AND METHODS: In our first study both hips in 14 healthy children (5-18 years old) were examined with US and MR
Here we present evidence that a fibroblast heparan sulphate proteoglycan of approx. 300 kDa and with a core protein of apparent molecular mass 70 kDa is covalently linked to the plasma membrane via a linkage structure involving phosphatidylinositol. Phosphatidylinositol-specific phospholipase C releases such a heparan sulphate proteoglycan only from cells labelled with [35S]sulphate in the absence
Three strains capable of mineralizing nonylphenol as sole carbon source were isolated from a sample of contaminated soil and characterized as two Pseudomonas spp. and a Stenotrophomonas sp. The two Pseudomonas spp. expressed characteristics typical of psychrophiles growing optimally of 10 °C and capable of growing at 0 °C. The Stenotrophomonas sp. was more likely psychrotrophic because it had an o
A new approach to the low cycle fatigue problem, based on non-linear fracture mechanics, is investigated. The method is designed to predict final failure of engineering structures containing cracks that are small compared to the significant length dimensions of the structure. The suggested procedure is simple to apply and the failure load can be predicted for a moderately low number of major load
Background: As part of a larger study whose objective is to develop an abbreviated version of the EORTC QLQ-C30 suitable for research in palliative care, analyses were conducted to determine the feasibility of generating a shorter version of the 4-item emotional functioning (EF) scale that could be scored in the original metric. Methods: We used data from 24 European cancer studies conducted in 10
Aim: To investigate whether there is any pharmacokinetic rationale for the common practice of administering vincristine to adolescents at relatively lower doses than those to younger children. Methods: A total of 98 children, aged 1.3-17.3 y, with acute lymphoblastic leukaemia (ALL) were studied on day I of induction therapy. Plasma samples were drawn before and 10, 30, 360 and 1380 min after inje
We have observed strong correlations between simultaneous and co-located measurements of aerosol optical depth and column amounts of carbon monoxide, hydrogen cyanide, formaldehyde and ammonia in bushfire smoke plumes over SE Australia during the Austral summers of 2001/2002 and 2002/2003. We show how satellite-derived aerosol optical depth maps may be used in conjunction with these correlations t
Analys av FW Murnaus Nosferatu (1922) och den fiktionaliserade berättelsen om inspelningen av filmen i Elias Merhiges Shadow of the Vampire (2000).
Anaerobic degradation of a semi-solid waste with a total solids content of 4% particulate matter, much of it insoluble, was investigated in four laboratory-scale reactors. Two of the reactors were equipped with different textile materials for immobilisation of microorganisms, while the other two were used as continuously-stirred-tank reactor references, A constant organic loading rate and hydrauli
Two new for science lichen species from the family Teloschistaceae (namely Caloplaca karadagensis Khodosovtsev & S. Kondr. and Caloplaca geleverjae Khodosovtsev & S. Kondr.) are described.
Lactobacillus isolates from healthy Estonian and Swedish children were characterised by a lectin typing technique; 56 isolates from six species (L. acidophilus, L. paracasei, L. plantarum, L. fermentum, L. brevis and L. buchneri) were tested. The typing system was based on an agglutination assay with a panel of six commercially available lectins, which,were chosen on the basis of their carbohydrat
