Abstract The chemical composition was studied and the difference between its rheological characteristics compared. Five samples were made of nutritional bars fortified with casein protein (A), whey (B), Milk concentrate (C), conjugated precipitates to which calcium salts (D) added. Iron (F) moisture content each A, B, C, D F samples, (12.9, 12.5, 16.5, 16.7, 11)%, respectively, percentage ash (...

The direction and the level of polarization of high energy photons emitted by astrophysics sources are valuable observables for the understanding of the corresponding emission mechanisms, source geometry and strength of magnetic fields at work. POLAR is a novel compact space-borne detector conceived for a precise measurement of hard X-ray polarization and optimized for the detection of Gamma-Ra...

POLAR is a novel compact space-borne Compton polarimeter conceived for a precise measurement of hard X-ray polarization and optimized for the detection of the prompt emission of Gamma-Ray Bursts (GRB) in the energy range 50−500 keV. A first detailed measurement of the polarization from astrophysical sources will lead to a better understanding of the source geometry and of the emission mechanism...

We present the results of UBV imaging of a large sample of irregular galaxies: 94 Im systems, 24 Blue Compact Dwarfs (BCDs), and 18 Sm galaxies. We also include JHK imaging of 41 of these galaxies. The sample spans a large range in galactic parameters. Ellipse fit axial ratios, inclinations, and position angles are derived, integrated photometry and azimuthally-averaged surface photometry profi...

STUDY OBJECTIVE Multiple studies have found that, compared with employees in other settings, workers in bars and restaurants have been exposed to high levels of secondhand smoke, putting them at increased risk for health complications. Among these bar employees are many women of low socioeconomic status (SES). Smoke free workplace ordinances have been extended to bars and restaurants in cities ...

The switching behavior of isolated nanoscale nickel and cobalt bars, which were fabricated using electron-beam lithography, was studied as a function of bar length. The bars have a 35 nm thickness, a 100 nm width, and a length varying from 200 nm to 5 mm. Magnetic force microscopy showed that except for the Ni bars with a length equal to or less than 250 nm, all other as-fabricated bars were si...
