Planar hall effect in ferromagnetic (Ga,Mn)As/GaAs superlattices
The planar Hall effect was used for investigation of magnetic anisotropy in short period (Ca,Mn)As/CaAs superlattices epitaxially grown on (001) oriented GaAs substrate. The results confirmed the existence of low-temperature magneto crystalline anisotropy in the superlattices with the easy magnetic axes directed along the two in-plane (100) directions. Attention is paid to the two-state behaviour
On chloride induced reinforcement corrosion in marine concrete
First stars VI - Abundances of C, N, O, Li, and mixing in extremely metal-poor giants. Galactic evolution of the light elements
We have investigated the poorly-understood origin of nitrogen in the early Galaxy by determining N abundances from the NH band at 336 nm in 35 extremely metal-poor halo giants, with carbon and oxygen abundances from Cayrel et al. (2004, A&A, 416, 1117), using high-quality ESO VLT/UVES spectra (30 of our 35 stars are in the range -4.1
En barbar i Beirut II
Essän handlar om dagens Libanon och berör de kraftmätningar och konfliktlinjer som skakar landet såväl inifrån som utifrån (regionala och globala intressen). Den är ett slags fortsättning på en artikel om Beiruts förhistoria som tidigare publicerats i Ord & Bild (nr 6/2004) – och kommer att utgöra en del av ett större arbete som publiceras i bokform i början av 2007 på Glänta förlag.
Influence of environmental factors on the frost resistance of concrete : a contribution to the BRITE/EURAM project BREU-CT92-0591 "The Residual Service Life of Concrete Structures"
This report investigates how the ability of a concrete to withstand frost attack depends not only of the concrete itself but also on the internal and external climatic factors. All those internal and external factors and their interaction are discussed.
Organizational climate in air traffic control - Innovative preparedness for implementation of new technology and organizational development in a rule governed organization
A positive and innovative organizational climate is of great importance in order to manage and adapt to change. Such a climate seldom evolves in organizations closely governed by rules and regulations. Because of ongoing organizational and technical changes within the Swedish Air Navigation Services Provider, a study concerning the organizational climate for changes and innovations was conducted t
Incidence of hospitalized osteoporotic fractures in cohorts with high dietary intake of persistent organochlorine compounds.
To trill or not to trill? Territorial response to a heterospecific vocal trait in male collared doves, Streptopelia decaocto
Responding of individuals outside the conspecific range has been largely explained by biases in sensory or cognitive systems toward particular traits or trait values. More recently, it has been shown that such responses might occur if individuals still respond to signal traits that have been lost over time. However, empirical evidence remains scarce. We report a case supporting the latter mechanis
An Integrated System-On-Chip Test Framework
In this paper we propose a framework for the testing of system-on-chip (SOC), which includes a set of design algorithms to deal with test scheduling, test access mechanism design, test sets selection, test parallelization, and test resource placement. The approach minimizes the test application time and the cost of the test access mechanism while considering constraints on tests, power consumption

Direct assessment of microbial colonisation in damp houses by chemical marker analysis
Ergosterol was used as a marker of fungal biomass and 3-hydroxy fatty acids were used as markers of bacterial endotoxin to determine microbial colonisation of building materials by gas chromatography-mass spectrometry. Pieces (0.3-0.5 g) of materials from two water-damaged buildings were hydrolysed to liberate the markers from larger microbial structures; the preparations were then purified, deriv

Structural consequences of neopullulanase mutations
Bacillus stearothermophilus neopullulanase (NPL) structure was modeled based on Aspergillus oryzae alpha-amylase (TAA) to understand the structure-function relationships of this pullulan hydrolyzing enzyme. The NPL structure seems to consist of a central (alpha/beta)(8) barrel to which the other domains are attached. The immediate surroundings of the NPL catalytic site were found to have very simi
On the computation of Hilbert series and Poincaré series for algebras with infinite Gröbner bases
In this paper we present algorithms to compute finite state automata which, given any rational language, recognize the languages of normal words and n-chains. We also show how these automata can be used to compute the Hilbert series and Poincaré series for any algebra with a rational set of leading words of its minimal Gröbner basis.
Ultrasound examination of soft tissue injury of the lower limb in athletes
We performed ultrasonography on 32 athletes complaining of intense pain in a swollen and tender thigh or calf after a contusion or stretching trauma. The ultrasonogram was used to visualize the presence and size of a suspected hematoma. The findings included the following: 7 patients with a circumscribed, anechoic lesion compatible with a liquefied hematoma; 10 patients with a circumscribed lesion
C(2)-ceramide influences the expression and insulin-mediated regulation of cyclic nucleotide phosphodiesterase 3B and lipolysis in 3T3-L1 adipocytes.
Cyclic nucleotide phosphodiesterase (PDE) 3B plays an important role in the antilipolytic action of insulin and, thereby, the release of fatty acids from adipocytes. Increased concentrations of circulating fatty acids as a result of elevated or unrestrained lipolysis cause insulin resistance. The lipolytic action of tumor necrosis factor (TNF)-alpha is thought to be one of the mechanisms by which
Structure and expression of the human cystatin C gene
The structural organization of the gene for the human cysteine-proteinase inhibitor cystatin C was studied. Restriction-endonuclease digests of human genomic DNA hybridized with human cystatin C cDNA and genomic probes produced patterns consistent with a single cystatin C gene and, also, the presence of six closely related sequences in the human genome. A 30 kb restriction map covering the genomic
Human papilloma virus in skin, mouth and uterine cervix in female renal transplant recipients with or without a history of cutaneous squamous cell carcinoma
Some human papilloma viruses are thought to be associated with skin cancer. In this pilot study, 21 female renal transplant carriers, 10 with a history of skin squamous cell carcinoma and 11 without, together with 9 age-matched healthy women were investigated for human papilloma virus DNA in sun-exposed (forehead) and less sun-exposed (buttock) skin, mouth and uterine cervix.
