We present rock magnetic and palaeointensity data from Holocene Icelandic lava flows, including historical and pre-historical lavas. Susceptibility versus temperature measurements indicate that the magnetic mineralogy is dominated by primary titanomagnetite that have experienced variable degrees of high-temperature oxidisation. The analyses also demonstrate that virtually all studied samples are t

The size of the anisotropic domains in a lyotropic liquid crystal is estimated using a new protocol for diffusion NMR. Echo attenuation decays are recorded for different durations of the displacement-encoding gradient pulses, while keeping the effective diffusion time and the range of the wave vectors constant. Deviations between the sets of data appear if there are non-Gaussian diffusion processe

Bet-hedging is defined as a strategy that reduces the temporal variance in fitness at the expense of a lowered arithmetic mean fitness. After a few technical points, we will here argue that this definition of bet-hedging is badly suited for models with density- and/or frequency-dependent fitness. A strict interpretation cannot be employed; possibly, a modified definition is necessary.

The estimated quantity of cement for construction and sealing purposes is around 9E5 kg in the planned Swedish KBS3 repository for nuclear waste. The highly alkaline cement pore fluid (pH > 12) may affect other components in the repository, and especially the bentonite buffer is of concern. In this study, we simulated possible interactions between cement and bentonite by contacting highly compacte

Early B cell factor (EBF)-1 is a transcription factor known to be of critical importance for early B lymphocyte development. EBF-1 has been shown to directly interact with and regulate expression of a set of genes involved in the functional formation of the preB cell receptor, but the dramatic phenotype observed in the EBF-1-deficient mice suggests that several additional genes are activated by th

The gene for protein D, a membrane-associated protein with specific affinity for human immunoglobulin D, was cloned from a nontypeable strain of Haemophilus influenzae. The gene was expressed in Escherichia coli from an endogenous promoter, and the gene product has an apparent molecular weight equal to that of H. influenzae protein D (42,000). The complete nucleotide sequence of the gene for prote

A technique of fluorescence multiplexing is described for analysis of the plasma membrane proteome of colorectal cancer cells from surgically resected specimens, enabling detection and immunophenotyping when the cancer cells are in the minority. A single-cell suspension was prepared from a colorectal tumour, and the mixed population of cells was captured on a CD antibody microarray. The cancer cel

BACKGROUND: Asthma guidelines recommend that long-acting inhaled beta-agonists should be used as maintenance therapy for patients with asthma inadequately controlled on an inhaled corticosteroid. We studied the safety and efficacy of the long-acting beta-agonist formoterol compared with terbutaline, each taken as needed, in patients with moderate to severe asthma. METHODS: Patients were taking an

Objective: The purpose of this investigation was to estimate the vertical deviation of the nasal floor and to register dental disturbances (i.e., hypo- and hyperdontia) in patients with an isolated soft tissue cleft lip. Design: Thirty patients with isolated cleft lips were randomly selected from the files of the Department of Maxillo-Facial Surgery and Jaw Orthopedics. As a matched control group,

The objective of the study was to evaluate the intestinal tolerance of a newly developed food containing Lactobacillus plantarum 299v, in children. The effects of consumption of the product on the children's nutrient intake were also followed, in a separate study. The tolerance study was parallel, double-blind, and included 69 children between 6 months and 3 years of age, randomized into two group

Public health policies in most European countries are concerned with how to keep older people living independently with a qualitatively good life in the community as long as possible. However, knowledge about what may characterise those seemingly 'healthy' older people is sparse. The aim of the study was to investigate the characteristics of a sample of people (75+) reporting various degrees of Qu

Antibodies provide some protection against cytomegalovirus-mediated disease. All aspects of antibody recognition of important viral antigens are however not fully appreciated. Glycoprotein B (gB), a key protein in the viral membrane, participates in viral infection and it is a component of prototype vaccines. By using combinatorial antibody library and selection technology, novel antibody specific

Large international biobank studies can make substantial contributions to scientific research by validation of the biological importance of previous research and by identification of previously unknown causes of disease. However, regulations for patient consent that are too strict and discrepancies in national policies on informed consent might hinder progress. Therefore, establishment of common g

Abstract in Undetermined NMR line shape analysis and relaxation dispersion measurements for N,N-dimethyltrichloroacetamide (DMTCA) weakly aligned using poly-γ-benzyl-l-glutamate, which forms a lyotropic nematic phase when dissolved in chloroform, were used to characterize chemical exchange kinetics for the rotation around the C−N amide bond. At low temperatures (<312 K), slow-exchange 1H-coupled 1

Early Eocene spores and pollen assemblages from the uppermost part of the Stolle Klint Clay and the overlying Fur Formation are diverse and well preserved. The terrestrial microflora comprises 42 species of spores and 108 species of pollen and four spores and pollen zones are established i.e. Interpollis velum-Labrapollis globosus, Basopollis atumenscens, Basopollis orthobasalis and Thomsonipollis

The molecular mobility in a hexagonal DNA-cationic surfactant complex is studied using H-1 and C-13 nuclear magnetic resonance spectroscopy. The charge-compensated complex can swell in water up to a content of approximately seven water molecules per charge. The NMR measurements show that in the dry state the alkyl chains of the surfactant have the properties of a disordered solid with internal mot

We summarize the activities of Working Group 2 of the HERA/LHC Workshop dealing with multi-jet final states and energy flows. Among the more specific topics considered were underlying event and minimum bias, rapidity gaps and survival probabilities, multi-jet topologies and multi-scale QCD, and parton shower–matrix element matching.
