Interaction between two spheres placed in tandem arrangement in steady and pulsating flow

The interaction among two spheres in tandem formation are studied for a Reynolds number of 300 using both steady and pulsating inflow conditions. The purpose is to further investigate the force characteristics as well as the shedding patterns of the two spheres as the separation distance is changed from 1.5 to 12. sphere diameters. The method used for the simulations is the volume of solid (VOS) m

Highlights from PHENIX I

This contribution highlights recent results from the PHENIX Collaboration at RHIC. It covers global variables, flow and 2-particle correlations. A second contribution in this issue, by T C Awes (2008 J. Phys. G: Nucl. Part. Phys. 35 104007), covers PHENIX results on heavy quarks, leptons and photons.

The effect of elevated pressures on the laminar burning velocity of methane plus air mixtures

In spite of the large amount of research spent on the evaluation of the high pressure dependence of laminar burning velocity of methane + air flame, there still exists a large uncertainty in the data for various reasons. In order to reduce the scatter to acceptable levels, the Heat Flux Method (HFM), known as a potential method with high accuracy, has been extended to higher pressures. New measure

The 9p21.3 risk of childhood acute lymphoblastic leukaemia is explained by a rare high-impact variant in CDKN2A.

Genome-wide association studies (GWAS) have provided strong evidence for inherited predisposition to childhood acute lymphoblastic leukaemia (ALL) identifying a number of risk loci. We have previously shown common SNPs at 9p21.3 influence ALL risk. These SNP associations are generally not themselves candidates for causality, but simply act as markers for functional variants. By means of imputation

The business model of solid waste management in Sweden – A case study of two municipally-owned companies

Abstract in UndeterminedThis paper describes the business model of municipally-owned MSW (municipal solid waste) companies in Sweden. A comparative study of two of these companies shows that they combine three types of activities: public service activities that collect solid waste from households, commercial establishments, and industry; processing activities that transform this waste; and marketi

Antiproliferative effects of curcuphenol, a sesquiterpene phenol.

Curcuphenol is a sesquiterpene isolated from sponges and plants having several significant biological activities. The present study explored its effect on cell proliferation and apoptosis in Caco-2 human colon cancer cells. It was demonstrated that curcuphenol in concentrations in the range of 29-116microg/ml inhibited cell proliferation and DNA replication and induced cell death in a dose-depende

Lund University Supports Publishing in OA Journals

In the 2009 budget Lund university has approved of funding publication fees in Open Access journals with 163,000$ with the intention to encourage and assist publishing in open access journals. The fund will be managed by Lund University Libraries, Head Office. This is one of the largest funds allocated at a university in support of publishing in OA journals.

P1PK: the blood group system that changed its name and expanded.

The antigens in the P1PK blood group system are carried on glycosphingolipids. The system currently includes three different antigens, P1, Pk, and NOR. The P1 antigen was disovered in 1927 by Landsteiner and Levine, and Pk and NOR were described in 1951 and 1982, respectively. As in the ABO system, naturally occurring antibodies of the immunoglobulin (Ig) M or IgG class, against the missing carboh

Optimal control of peridinin excited-state dynamics

Optimal control is applied to study the excited-state relaxation of the carbonyl-carotenoid peridinin in solution. Phase-shaping of the excitation pulses is employed to influence the photoinduced reaction dynamics of peridinin. The outcome of various control experiments using different experimentally imposed fitness parameters is discussed. Furthermore, the effects of pump-wavelength and different

The evolution of eyes and visually guided behaviour

The morphology and molecular mechanisms of animal photoreceptor cells and eyes reveal a complex pattern of duplications and co-option of genetic modules, leading to a number of different light-sensitive systems that share many components, in which clear-cut homologies are rare. On the basis of molecular and morphological findings, I discuss the functional requirements for vision and how these have

Hypertension, cardiovascular risk and polymorphisms in genes controlling the cytochrome P450 pathway of arachidonic acid: A sex-specific relation?

Hypertension is a multifactorial disease in which the interplay of genetic and environmental factors that maintain blood pressure stable throughout life is altered. Cytochrome P450 (CYP)-derived metabolites of arachidonic acid such as epoxyeicosatrienoic acids (EETs) and 20-hydroxyeicosatetraenoic acid (20-HETE), active on vascular tone, endothelial function and renal sodium reapportion, have been

Healthy Lifestyle and Leukocyte Telomere Length in US Women

Context: Whether a healthy lifestyle may be associated with longer telomere length is largely unknown. Objectives: To examine healthy lifestyle practices, which are primary prevention measures against major age-related chronic diseases, in relation to leukocyte telomere length. Design and Setting: Cross-sectional analysis in the Nurses' Health Study (NHS). Participants: The population consisted of
