The glaciation of a cumulus cloud over New Mexico

The Met Office Cloud Resolving Model (CRM) and the UMIST Explicit Microphysics Model (EMM) have been employed in the analysis of data from airborne studies of a multi-thermal cumulus cloud which developed over New Mexico in the summer of 1987. The principal goal was to establish a quantitative understanding of the observed development of glaciation of this cloud. The EMM was utilized in a series o

Stability of Sn-100(50)50 deduced from excited states in Cd-99(48)51 stability of

Excited states of neutron deficient nuclei close to Sn-100 were investigated in an in-beam spectroscopic experiment using the NORDBALL detector array. Excited states in Cd-99 were identified for the first time. The measured half-life of an isomeric state in Cd-99 indicates that the stability with respect to quadrupole shape changes is as large in Sn-100 as for other heavy doubly magic nuclei.

Association between contact hip stress and RSA-measured wear rates in total hip arthroplasties of 31 patients

BACKGROUND: The main concern in the long run of total hip replacements is aseptic loosening of the prosthesis. Optimization of the biomechanics of the hip joint is necessary for optimization of long-term success. A widely implementable tool to predict biomechanical consequences of preoperatively planned reconstructions still has to be developed. A potentially useful model to this purpose has been

C-erbB2, p27 and G1/S aberrations in human primary breast cancer

Background: C-erbB2 is overexpressed in approximately one-fourth of human breast cancers. In spite of numerous reports suggesting a connection of c-erbB2 overexpression with cell cycle regulation through p27, D cyclins and c-myc. the relationship between c-erbB2 and proliferation through de-regulation of the pRb pathway in primaty breast cancer has not been fully clarified. Materials and Methods:

Grids for scientific computing: Minisymposium abstract

Grid technologies are still evolving, with standards yet to be defined and reliable production-level solutions yet to be found. Nevertheless, Grid already stepped out of the cradle and slowly but steadily finds its way to the world of the modern information technologies. Early testers and adopters of this innovative technology are researchers in various fields of science, primarily those that trad

Evidence for inhibitory effect of the agonist gaboxadol at human alpha(1)beta(2)gamma S-2 GABA(A) receptors

Gaboxadol (THIP; 4,5,6,7-tetrahydroisoxazolo[5,4-c]pyridin-3-ol) is an agonist at GABA(A) receptors. THIP concentrations (0.01-50 mM) were applied rapidly to Sf9 cells expressing the human alpha(1)beta(2)gamma(2S) GABA(A) receptors. The EC50 values for the peak current in THIP alone or THIP plus 1 muM diazepam were 154 and 53 muM, respectively. In supersaturating THIP (10-50 mM) the rate of curren

Low density and high affinity of platelet [H-3]paroxetine binding in women with bulimia nervosa

Impaired serotonin transmission has been suggested to be implicated in the pathophysiology of bulimia nervosa. As an indirect measure of brain serotonergic activity, the binding of tritiated ligands to platelet serotonin transporters has been studied in bulimia nervosa as well as in other putatively serotonin-related psychiatric disorders. In this study, the density and affinity of platelet seroto

Oxidative fragmentation of the bridged beta-triketone core of hyperforin

The beta-triketone core of the antidepressant phloroglucinol hyperforin (1) undergoes a series of peroxide-induced oxidative rearrangements leading to compound 5, which is formed by opening of ring A, and compound 6, which is formed by removal of the C-1 carbonyl bridge. A mechanistic rationale for this process is proposed. ((C) Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2004).

Design and dosimetry characteristics of a soft-docking system for intraoperative radiation therapy

PURPOSE: The design concept and the dosimetric characteristics of an applicator system for intraoperative radiation therapy (IORT) with special emphasis on alignment methods, the effect of a plastic scatterer in the beam, radiation leakage, and misalignment dosimetry, are presented in this paper. MATERIALS AND METHODS: A soft-docking system for a linear accelerator, which enables collimation of el

Effects of a large-scale introduction of the pneumococcal polysaccharide vaccine among elderly persons in Stockholm, Sweden

In October 1998 Stockholm County launched a 3-year vaccination campaign with the 23-valent pneumococcal polysaccharide vaccine (PPV-23) directed towards all elderly persons. We analysed the impact of this campaign on the incidence and serotype distribution of invasive pneumococcal disease (IPD) in Stockholm County, where the vaccine coverage was 36%, as compared to Skane County, where no vaccinati

The complement: A solution to liquid drop finite size effects in phase transitions

The effects of the finite size of a liquid drop undergoing a phase transition are described in terms of the complement, the largest (but mesoscopic) drop representing the liquid in equilibrium with the vapor. Vapor cluster concentrations, pressure, and density from fixed mean density lattice gas (Ising) calculations are explained in terms of the complement generalization of Fisher's model. Account

Boundary conditions in the envelope function approximation as applied to semiconductor heterostructures: The multi-band case

We have found the equations that determine the self-adjoint extensions, and thus the boundary conditions, of the differential operator used in the multi-band k.p-theory, when the coefficients in the Kane-matrix are piecewise constant. Both the one-dimensional and the three-dimensional case have been investigated. A numerical calculation shows that the choice of boundary conditions affects the ener

Cross-platform classification in microarray-based leukemia diagnostics

Gene expression profiling is a powerful technique for classifying hematologic malignancies. Its clinical use is, however, currently hindered by the need to collect large sets of expression profiles at each diagnostic facility. To overcome this limitation, we introduced cross-platform classification, allowing classifier construction using pre-existing microarray datasets. As proof-of-principle, we

Chlorhexidine for prevention of neonatal colonization with group B streptococci. III. Effect of vaginal washing with chlorhexidine before rupture of the membranes

A single vaginal washing with 2 g/l of chlorhexidine was performed before rupture of the membranes in 19 parturients who were urogenital carriers of group B streptococci (GBS). Two (11%) of the infants became colonized immediately after birth, in contrast to 16 of 41 (39%) infants to controls (P = 0.02). A significant reduction of GBS colonization of the ear (P = 0.02) and umbilicus (P = 0.01) was

Fermentation strategies for improved heterologous expression of laccase in Pichia pastoris.

Improved expression of recombinant laccase by Pichia pastoris carrying the lcc1 cDNA isolated from Trametes versicolor was achieved by optimization of the cultivation conditions in a fermentor equipped with a methanol sensor system. The results indicated that the activity obtained in fermentor cultivations was at least 7 times higher than in shake-flask cultures. Three different strategies for fer

Weak convergence of currents

We give certain condictions to guarantee weak convergence $u_kT_k \rightarrow uT$, where $u_k$, $u$ are plurisubharmonic functions and $T_k$, $T$ are positive closed currents. As applications we obtain that convergence in capacity of plurisubharmonic functions $u_k$ implies weak convergence of the complex Monge-Amp\`ere measures $(dd^cu_k)^n$ if all of the plurisubharmonic functions $u_k$ are boun

Metabolic rate and thermal conductance of lemmings from high-arctic Canada and Siberia

The arctic climate places high demands on the energy metabolism of its inhabitants. We measured resting (RMR) and basal metabolic rates (BMR), body temperatures, and dry and wet thermal conductances in summer morphs of the lemmings Dicrostonyx groenlandicus and Lemmus trimucronatus in arctic Canada, and the BMR of D. torquatus, D. groenlandicus, L. sibiricus, L. bungei and L. trimucronatus in Sibe

Association of overweight with increased risk of coronary heart disease partly independent of blood pressure and cholesterol levels - A meta-analysis of 21 cohort studies including more than 300,000 persons

Background: The extent to which moderate overweight (body mass index [BMI], 25.0-29.9 [calculated as weight in kilograms divided by height in meters squared]) and obesity ( BMI, >= 30.0) are associated with increased risk of coronary heart disease (CHD) through adverse effects on blood pressure and cholesterol levels is unclear, as is the risk of CHD that remains after these mediating effects are

Schizophrenia: From the brain to peripheral markers. A consensus paper of the WFSBP task force on biological markers

Objective. The phenotypic complexity, together with the multifarious nature of the so-called schizophrenic psychoses, limits our ability to form a simple and logical biologically based hypothesis for the disease group. Biological markers are defined as biochemical, physiological or anatomical traits that are specific to particular conditions. An important aim of biomarker discovery is the detectio
