OGLE-2009-BLG-076S: THE MOST METAL-POOR DWARF STAR IN THE GALACTIC BULGE

Measurements based on a large number of red giant stars suggest a broad metallicity distribution function (MDF) for the Galactic bulge, centered on [Fe/H] approximate to -0.1. However, recently, a new opportunity emerged to utilize temporary flux amplification (by factors of similar to 100 or more) of faint dwarf stars in the Bulge which are gravitationally lensed, making them observable with high

Identifying work ability promoting factors for home care aides and assistant nurses

Background: In workplace health promotion, all potential resources needs to be taken into consideration, not only factors relating to the absence of injury and the physical health of the workers, but also psychological aspects. A dynamic balance between the resources of the individual employees and the demands of work is an important prerequisite. In the home care services, there is a noticeable t

Prosumenter i våra hus

Rapporten är en sammanställning av de aspekter som påverkar uppkomsten av nya byggnader med möjligheter till egen produktion av el samt möjligheter att installera elproduktionsanläggningar på befintliga byggnader. Följande frågor besvaras i rapporten: • Vilka begrepp och definitioner används i detta sammanhang? • Vilka elproducerande system kan användas av prosumenter i bostäder? • Vilka villkor o

Radiation protection of the patient in diagnostic radiology and nuclear medicine. Are we doing enough?

This paper deals with the radiation protection of patients in diagnostic radiology and nuclear medicine. Modern equipment like CT, PET/CT and SPECT/CT are very important in the daily hospital routine and there is a risk to overuse them, which results in unnecessarily high doses both collectively and to individuals. Detailed referral criteria are needed as well as improved education and training in

A module-based analytical strategy to identify novel disease-associated genes shows an inhibitory role for interleukin 7 Receptor in allergic inflammation

Background: The identification of novel genes by high-throughput studies of complex diseases is complicated by the large number of potential genes. However, since disease-associated genes tend to interact, one solution is to arrange them in modules based on co-expression data and known gene interactions. The hypothesis of this study was that such a module could be a) found and validated in allergi

The sex pheromones of two pine sawfly species, Gilpinia frutetorum and Gilpinia socia: Chemical identification, synthesis and biological activity

3,7-Dimethylpentadecan-2-ol and 3-methylpentadecan-2-ol were identified in female whole body extracts from the two pine sawfly species Gilpinia frutetorum and Gilpinia socia. This is the first observation of 3-methylpentadecan-2-ol in extracts of a female pine sawfly species. Synthetic and highly pure stereoisomers of 3,7-dimethylpentadecan-2-ol and 3-methylpentadecan-2-ol were used to verify that

Platinum(II) and gold(I) complexes based on 1,1 '-bis(diphenylphosphino)metallocene derivatives: Synthesis, characterization and biological activity of the gold complexes

The synthesis of series of 1,2,1' substituted bis(diphenylphosphino)- ruthenocenyl (1-4) and ferrocenyl cis-platinum(II) (5-7) and gold(I) (8-12) complexes are described. Crystal structures of 2 and 4, as well as 5, 6 and 10 confirm the molecular geometry of these ligands and their metal complexes. Preliminary investigation of four gold complexes as potential anticancer, antiHIV and antimalaria sh

Network modeling of the transcriptional effects of copy number aberrations in glioblastoma

DNA copy number aberrations (CNAs) are a hallmark of cancer genomes. However, little is known about how such changes affect global gene expression. We develop a modeling framework, EPoC (Endogenous Perturbation analysis of Cancer), to (1) detect disease-driving CNAs and their effect on target mRNA expression, and to (2) stratify cancer patients into long-and short-term survivors. Our method constr

The Spectrum of Fe II

The spectrum of singly ionized iron (Fe II) has been recorded using high-resolution Fourier transform (FT) and grating spectroscopy over the wavelength range 900 angstrom to 5.5 mu m. The spectra were observed in high-current continuous and pulsed hollow cathode discharges using FT spectrometers at the Kitt Peak National Observatory, Tucson, AZ and Imperial College, London and with the 10.7 m Norm

Ambipolar doping in quasifree epitaxial graphene on SiC(0001) controlled by Ge intercalation

The electronic structure of decoupled graphene on SiC(0001) can be tailored by introducing atomically thin layers of germanium at the interface. The electronically inactive (6 root 3 x 6 root 3)R30 degrees reconstructed buffer layer on SiC(0001) is converted into quasi-free-standing monolayer graphene after Ge intercalation and shows the characteristic graphene pi bands as displayed by angle-resol

Does Economics Have a Gender?

We are pleased that our paper on gender balance in the economics profession incited a number of commentaries on "Why few women in economics?" ( all in May 2008 Econ Journal Watch). The commentators include one sociologist, one psychologist, and three non-traditional economists-making for great breadth. Here we address the issues that seem most important to us. Our paper provided original documenta
