Isomeric States in the Light Tc Isotopes

Preliminary results from the first experiment of the Stopped Beam RISING campaign are presented. The relativistic projectile fragmentation of a 750 MeV/u beam of Ag-107 populated isomeric states in very neutron deficient nuclei at the proton dripline around mass 80-90. Nuclei were unambiguously identified using the FRagment Separator (FRS) and its ancillary detectors located at GSI. The ions produ

Recruitment of resting stages may induce blooms of Microcystis at low N : P ratios

Some species of cyanobacteria form resting stages at the sediment surface when environmental conditions become unfavourable. As conditions turn more favourable, these resting stages hatch to the water phase, where the cells grow, reproduce, and sometimes form blooms. Since blooms of cyanobacteria have become an increasing threat to inland and brackish waters, it is important to assess the mechanis

LDCMC version1.0

We present the LDCMC program implementing the Linked Dipole Chain model for deeply inelastic ep scattering within the framework of the Ariadne event generator.

New data for sandwich panels on the correlation between the SBI test method and the room corner reference scenario

Assessment of the fire behaviour of sandwich panels is continuously under discussion. The fire behaviour of these panels is a combination of material characteristics such as the core material and mechanical behaviour of the panels such as joints, dilations etc. The use of small or intermediate scale tests can be questioned for such types of products. Within the proposed European product standard

Application of standard addition methodology for the determination of banned azo dyes in different leather types

An analytical procedure based on microwave-assisted extraction (MAE) and standard addition was applied for the determination of banned azo dyes in bovine, sheep, and goat leather. Standard addition at four different concentration levels was performed using azo dyes, dissolved either in methanol or water. All dyes were determined indirectly by measuring their corresponding harmful aromatic amines,

Immunoglobulin heavy G2 chain (IGHG2) gene restriction in the development of severe respiratory syncytial virus infection

Aim: Respiratory syncytial virus (RSV) is a prominent cause of airway morbidity in children under 1 y of age. It is assumed that host factors influence the severity of disease presentation, and thus the need for hospitalization. The variation of IGHG genes from chromosome 14q32 are linked to serum IgG subclass levels but also to the variations in IgG responses to pneumococcal, meningococcal and Ha

Sulphate resistance of self-compacting concrete

This article outlines a laboratory study on sulphate resistance of self-compacting concrete (SCC). For this purpose, more than 40 cylinders of concrete were subjected to a solution with sodium sulphate, sea or distilled water during 900 days. Age at start of testing was either 28 or 90 days. Weight and internal fundamental frequency (IFF) were measured. Comparison was done with the corresponding p

Regulation of violaxanthin de-epoxidase activity by pH and ascorbate concentration

The activity of violaxanthin de-epoxidase has been studied both in isolated thylakoids and after partial purification, as a function of pH and ascorbate concentration. We demonstrate that violaxanthin de-epoxidase has a Km for ascorbate that is strongly dependent on pH, with values of 10, 2.5, 1.0 and 0.3 mM at pH 6.0, 5.5, 5.0 and 4.5, respectively. These values can be expressed as a single Km±0.

Relationship between testosterone levels, insulin sensitivity, and mitochondrial function in men

OBJECTIVE - The goal of this study was to examine the relationship between serum testosterone levels and insulin sensitivity and mitochondrial function in men, RESEARCH DESIGN AND METHODS - A total of 60 men (mean age 60.5 +/- 1.2 years) had a detailed hormonal and metabolic evaluation. Insulin sensitivity was measured Using a hyperinsulinemic-euglycemic clamp. Mitochondrial function was assessed

Total abrogation of collagen II-induced arthritis and the B cell response to type II collagen using suboptimal doses of a topoisomerase II antagonist.

BACKGROUND: Collagen-induced arthritis (CIA) is the most commonly used model of rheumatoid arthritis (RA). In both CIA and RA there is an increase in the cellular content of the synovium, this being dominated by macrophages. OBJECTIVE: To assess the impact of etoposide, a topoisomerase II antagonist known to induce monocyte apoptosis, on the development of CIA. METHODS: Mice were primed and booste

The association of DNA and stable catanionic amino acid-based vesicles

Cationic surfactants associate strongly to DNA and compact but are often toxic. The interaction of some novel cationic amino acid-based surfactants, which may enhance transfection and appear to be nontoxic, is described. A cationic arginine-based surfactant, ALA, gives in combination with anionic surfactants spontaneously stable vesicles, and special attention is given to the association of these

Collective excitations and band termination in Nb-85

High-spin states in Nb-85 were studied using the GAMMASPHERE Ge detector array and the MICROBALL charged-particle detector system. Three gamma-ray cascades with collective rotational characteristics were observed. One of the bands exhibits a forking at the top, most likely reflecting the termination of one branch into a favoured non-collective, near spherical state. The data are interpreted in ter

Liposuction of arm lymphoedema.

Breast cancer is the most common disease in women, and up to 38% develop lymphedema of the arm following mastectomy, standard axillary node dissection and postoperative irradiation. Limb reductions have been reported utilising various conservative therapies such as manual lymph and pressure therapy. Some patients with long-standing pronounced lymphedema do not respond to these conservative treatme

Global core recommendations for a musculoskeletal undergraduate curriculum

Objective: To develop core recommendations for the learning outcomes of an undergraduate curriculum in musculoskeletal conditions for any parts of the globe. Methods: Recommendations were developed by wide consultation with experts in orthopaedics, rheumatology, osteoporosis, and rehabilitation from all parts of the world who had interest and experience in these specialties, with the support of in

Lower limb fractures and registration for alcoholism

During two consecutive years 607 individuals with lower limb fractures were diagnosed. Half of the individuals, 315, were women and only 14 of them had an earlier registration for alcoholism. In the 292 men, however, 73 men or 25%, had been registered at the Department of Alcohol Diseases at least once during the 13 years of observation, the highest registration frequency (30%) was noted in the ma
