The class of norm-dependent random matrix ensembles is studied in the presence of an external field. The probability density of the ensemble depends on the trace of the squared random matrices, but is otherwise arbitrary. An exact mapping to superspace is performed. A transformation formula is derived which gives the probability density in superspace as a single integral over the probability densi

In the first of two papers, the atmospheric poly brominated diphenyl ether (PBDE) concentrations at a municipal solid waste incineration (MSW) plant with electronic recycling is compared with that at an industrial urban reference site producing asphalt and concrete. In the second paper, atmospheric deposition and washout behaviour is presented (Atmos. Environ. (2004a)). PBDEs (BDE28, -47, -66, -10

In the present study, we have investigated the effects of extracellular redox status and metal/thiol interactions on glutathione distribution in HeLa cell cultures. No effects were seen on glutathione distribution after the addition of different thiols, whereas the pro-oxidant copper ions affected glutathione distribution in several ways. The addition of dithiothreitol (DTT) but not the other thio

Elongation factor G (EF-G) is a G protein factor that catalyzes the translocation step in protein synthesis on the ribosome. Its GTP conformation in the absence of the ribosome is currently unknown. We present the structure of a mutant EF-G (T84A) in complex with the non-hydrolysable GTP analogue GDPNP. The crystal structure provides a first insight into conformational changes induced in EF-G by G

The performance of poly(1-trimethylsilyl-1-propyne) (PTMSP)/silica nanocomposites was studied for membranes with a filler content between 0 and 50 wt%. An increase in permeability and a decrease in vapor selectivity was measured with increasing filler content. The free volume sizes and interstitial mesopore sizes of the composites were determined by use of positron annihilation lifetime spectrosco

The Swedish sound string /at/ (graphically: att) is associated with two grammatical functions: a) (part of) a subordinate conjunction and b) as an infinitive marker. Previous studies connect final lengthening and pauses with prosodic and syntactic boundaries in spoken discourse. Following these findings, this pilot study, with 5 short spontaneous discourses from 3 male speakers shows a correlation

We show that the smooth traveling waves of the Camassa-Holm equation naturally correspond to traveling waves of the Korteweg-de Vries equation.

Heating of 1'-(N-substituted carbamoyl)methylspiro[2H-1-benzopyran-2,2'-[2H]indoles] with potassium hydroxide in ethanol yields diastereomeric 5a,13-methano-6H-1,3-benzoxazepino[3,2-a]indole-12-carboxamides. Reduction of the latter with sodium borohydride affords 1,2,3,9a-tetrahydro-2-hydroxyaryl-9H-pyrrolo[1,2-a]indole-3-carboxamides .

Omorganisationer i form av marknadsorienterade beställar-utförarmodeller och effektivisering har sedan början av 1990-talet fått mycket stor omfattning inom offentlig sektor. De startade utan några vetenskapliga stöd för att de nya formerna skulle resultera i bättre kvalitet i tjänsterna. Resultat från en tioårig empirisk studie inom hemtjänsten pekar i stort på ingen eller negativ inverkan på arb

We report on "safe" Coulomb excitation of neutron-rich (138,140,142) Xe nuclei. The radioactive nuclei have been produced by ISOLDE at CERN and post-accelerated by the REX-ISOLDE facility. The gamma-rays emitted by the decay of excited states have been detected by the MINIBALL array. Recent results are presented.

The inception of the sheet flow regime as well as the effects of the phase lag when the sheet flow regime is established were investigated for oscillatory flows and combined steady and oscillatory flows. A new criterion for the inception of sheet flow is proposed based on around 300 oscillatory flow cases from experiments. This criterion was introduced in the Camenen and Larson [Camenen, B., Larso

The blood group ABO gene shows considerable polymorphism in most of the 7 exons. Introns examined so far have also shown blood group-related polymorphisms, as has an upstream enhancer region. Several polymorphisms affect the specificity of the gene product (glycosyltransferase) and explain the occurrence of blood group A and B. Various lethal mutations result in blood group O. Other mutations are

Popular Abstract in Swedish S:t Germer och s:t Josse var två helgon som levde i norra Frankrike på 600-talet. Deras liv nedtecknades ganska kort tid efter deras död i tre olika versioner av författare som skrev på latin. I början av 1200-talet sammanställde Pierre de Beauvais detta material till två diktverk på franska, skrivna på åttastavig vers, 874 respektive 820 versar. Avhandlingen är en kritThe Life of Saint Germer and the Life of Saint Josse are two poems consisting of 874 and 820 octosyllabic verses respectively. They were written in the beginning of the 13th century by Pierre de Beauvais. The two poems are preserved in one manuscript only, the Grand recueil la Clayette, Paris, Bibl. nat. Nouv. acq. fr. 13521, written in the latter half of the 13th century by a scribe who was from

A section of the Vitabdck Clays at Eriksdal in southern Sweden was sampled for vertebrate fossils. Large bulk samples were collected from three horizons, including two coquina beds, VC3 and VC11, and a silty clay bed, VC7. Shark teeth are very common and constitute the main portion of the vertebrate material discussed herein. The selachian tooth faunas are almost exclusively represented by hybodon

Nodularin (Nod), produced by the brackish/marine cyanobacterium Nodularia spumigena, is a potent hepatotoxin, tumor promoter and is possibly carcinogenic to mammals. It is structurally and toxicologically related to the microcystins, produced by Microcystis aeruginosa in fresh water. A better understanding of the kinetics of Nod production might provide an insight into the physiological and ecolog
