Coordinates and 2MASS and OGLE identifications for all stars in Arp's 1965 finding chart for Baade's Window

Aims. We seek to provide 2MASS and OGLE identifications and coordinates for all stars in the finding chart published by Arp (1965, ApJ, 141, 43). This chart covers the low extinction area around NGC 6522, also known as Baade's window, at coordinates (l, b) = (1.02, -3.92). Methods. A cross correlation, using numerical techniques, was performed between a scan of the original finding chart from Arp

Magnetic phases of one-dimensional lattices with 2-4 fermions per site

We study the spectral and magnetic properties of one-dimensional lattices filled with 2-4 fermions (with spin-1/2) per lattice site. We use a generalized Hubbard model that takes into account all the interactions on a lattice site, and solve the many-particle problem by exact diagonalization. We find an intriguing magnetic phase diagram which includes ferromagnetism, spin-1 Heisenberg antiferromag

Jewish Thought, Utopia and Revolution

In respons to the grim realities of the present world, Jewish thought has not tended to retreat into eschatological fantasy, but rather to project utopian visions precisely onto the present moment, envisioning redemptions that are concrete, immanent, and necessarily political in nature. The purpose of this book is to contribute to the deeper understanding of the relationship between Jewish thought

Drugs prescribed by general practitioners according to age, gender and socioeconomic status after adjustment for multimorbidity level

Background: Age, gender and socioeconomic status have been shown to be associated with the use of prescription drugs, even after adjustment for multimorbidity. General practitioners have a holistic and patient-centred perspective and our hypothesis is that this may reflect on the prescription of drugs. In Sweden the patient may seek secondary care without a letter of referral and the liability of

History Reborn inFree Competition: The Czech and Slovak Post-communist Transitions and Their Dominant Historical Narratives Two of the four historical narratives presented here, the Czech national-liberal narrative and the Slovak national-European narrative, imbue Czech and Slovak history with national and democratic meaning, by using history to legitimize future aims in these areas. The two rema

Streptococci and Platelets - A Study of Host-Pathogen Interaction Dynamics

Invasive infections remains one of the leading causes of death due to infections over the world, and efficient treatment remains elusive. One of the major causes of sepsis and other invasive infections is pathogenic streptococci that cause a wide range of clinical manifestations in humans. Group A and group G streptococci have both been shown to cause both infections of milder ranges as well as se

Fibrin binds to collagen and provides a bridge for alpha V beta 3 integrin-dependent contraction of collagen gels

The functional significance of fibrin deposits typically seen in inflammatory lesions, carcinomas and in healing wounds is not fully understood. In the present study, we demonstrate that fibrinogen/fibrin specifically bound to native Col I (collagen type I) and used the Col I fibre network as a base to provide a functional interface matrix that connects cells to the Col I fibres through alpha V be

Development of a novel macrostructured cathode for large-area neutron detectors based on the B-10-containing solid converter

We present a novel design for a macrostructured cathode that can be coated with a thin layer of the B-10 solid converter and mounted to replace the Boron-lined flat parallel plates of a proportional counter used for slow neutron detection. The proposed design consists of a 3D regular pattern exhibiting millimeter deep grooves with an opening angle of alpha = 45 degrees, which could be created in t

Stability of (B4C)-B-10 thin films under neutron radiation

Thin films of (B4C)-B-10 have shown to be very suitable as neutron-converting material in the next generation of neutron detectors, replacing the previous predominantly used He-3. In this contribution we show under realistic conditions that (B4C)-B-10 films are not damaged by the neutron irradiation and interactions, which they will be exposed to under many years in a neutron detector. 1 mu m thic

Texture Caches

This column examines the texture cache, an essential component of modern GPUs that plays an important role in achieving real-time performance when generating realistic images. GPUs have many components and the texture cache is only one of them. But it has a real impact on the performance of the GPU if rasterization and memory tiling are set up correctly.

Solvolysis of Substituted Benzoyl Chlorides in Nonionic and Mixed Micellar Solutions.

The solvolysis of substituted benzoyl chlorides is sensitive both to substituent electronic effects and to medium effects. The solvolysis reactions of substituted benzoyl chlorides have been analyzed in the presence of nonionic micelles. The reaction is inhibited or catalyzed depending on the reaction mechanism, dissociative or associative, respectively. The micellar effects observed can be relate

Genomic Profiling, Mutations and Deranged Signaling in Esophageal Cancer and Hereditary Colorectal Cancer

Popular Abstract in Swedish Varje år drabbas i världen ca 3 miljoner individer av cancer i mag-tarmkanalen. Stora skillnader finns i incidens med magsäckscancer och matstrupscancer särskilt vanliga i utvecklingsländer, medan tjock- och ändtarmscancer är en av de vanligaste tumörtyperna i västvärlden. Cancer i mag-tarmkanalen ger ofta diffusa symtom, vilket i många fall leder till att tumörerna uppEsophageal cancer and colorectal cancer represents two major types of gastrointestinal tumors. Though refined surgery and introduction of novel chemotherapeutics have improved outcome, more than 2500 Swedes die from these diseases every year. Novel markers for early diagnosis, prognosis and treatment prediction are therefore needed. This thesis aimed to genetically profile esophageal cancer with c

Release of Ring Strain as Driving Force for Inversion of Stereochemistry - Application to the Synthesis of Ribopyranosides from Xylopyranosides

By using a Swern oxidation-epimerization-reduction sequence it is possible to selectively epimerize any position in isopropylidene-protected xylopyranosides, thus forming arabinosides, ribosides, and lyxosides. The driving force for epimerization of position 3 (xylo to ribo) is the release of ring strain by going from a 1,2-trans-acetal to a 1,2-cis-acetal.

Cancer risk in hospitalized sarcoidosis patients: a follow-up study in Sweden

Background: Sarcoidosis patients show dysregulated immune function, which may be related to subsequent cancer. We examined here the overall and specific cancer risks among Swedish subjects who had been hospitalized for sarcoidosis. Methods: A sarcoidosis research database was created by identifying hospitalized sarcoidosis patients from the Swedish Hospital Discharge Register and by linking them w
