Context. The contrast of granulation is an important quantity characterizing solar surface convection. Aims. We compare the intensity contrast at 630 nm, observed using the Spectro-Polarimeter (SP) aboard the Hinode satellite, with the 3D radiative MHD simulations of Vögler & Schüssler (2007). Methods. A synthetic image from the simulation is degraded using a theoretical point-spread function o...

Context. Among optical stellar interferometers, the CHARA Array located at Mt Wilson in California offers the potential of very long baselines (up to 330 m) and the prospect of coupling multiple beam combiners. This paper presents the principle and the measured performance of VEGA, Visible spEctroGraph and polArimeter installed in September 2007 at the coherent focus of the array. Aims. With 0....

Realtime ray tracing and interactive global illumination have recently made significant progress, allowing for ray traced rendering quality even in highly complex scenes. Nevertheless, high-quality global illumination is currently still limited to offline computations, as existing interactive techniques are applicable only to simple scenes, BRDFs, and/or lighting conditions. For realistically c...

The various PdCu-Mo2C interfaces are used to find out the interface stability and strength by means of first-principle calculations. It is revealed that orientation plays an important role in interfaces, i.e., Mo2C(001)/PdCu(110) possesses higher with work separation than corresponding Mo2C(100)/PdCu(110) Mo2C(010)/PdCu(112) interfaces. Calculations also reveal formation PdCu(110)-Mo2C(001), Pd...

Case Report A 33 months old girl is admitted in our hospital for recurrent episodes of arthritis and bone lesions. At the age of 18 months, she presented arthritis of the left knee associated to low-grade fever, leukocytosis and increased inflammatory markers; the arthrocentesis revealed a small amount of corpuscular liquid with a negative cultural test. The girl was treated with i.v. antibioti...

This report outlines the content of a one-day workshop on Generic Medicines that was held at KIST Medical College, Lalitpur, Nepal on 13(th) December 2010, which was attended by 32 delegates from different institutions in Nepal, including pharmacists, pharmacologists and medical doctors. Right medicine, right patient, right dose, right frequency and duration, right information and right monitor...

Introduction Familial Mediterranean Fever (FMF) is an autoinflammatory disease characterized by recurrent attacks of fever and serositis. A relation between FMF and Ankylosing Spondylitis (AS) has been suggested in small cohort studies, although there is no consensus regarding the role of HLA B27. Colchicine, the mainstay treatment in FMF, does not improve the axial or peripheral symptoms due t...

Introduction TNF receptor associated periodic syndrome (TRAPS) is a rare autosomal dominant disease characterized by episodes of fever usually lasting two to three weeks, associated with severe abdominal pain, arthralgia, skin rash and red and swollen eyes. The age of onset varies from early childhood to adulthood, and the disease affects both sexes equally. Although first cases were described ...
