it is proposed to use a single base platform in the persian gulf considering its low depth and more appropriate environmental conditions in comparison to north sea and mexico gulf where this kind of platform is very popular. the pile of platform is responsible for transmission of environmental loads resulted from waves, currents, wind and dead loads to foundation of platform. using sacs 5.3 sof...

Molecular hydrogen plays a key role in structure formation during the early Universe, sometimes cooling the gas and at other times heating it. We discuss three of the key chemical reactions controling the formation of H2 during the epoch of primordial galaxy and first star formation. These are the associative detachment (AD) reaction H−+H→ H2+ e−, the mutual neutral (MN) reaction H−+H+ → H+H, a...

Plethysmographic specific airways resistance (sRaw) has remained the most recognised measure of airway resistance for almost 60 years [1]. Studies in both adults and children (including preschoolers) suggest clinical utility across important obstructive lung diseases [2–5]. Measurement protocols based on rapid panting or tidal breathing exist, and are incorporated into many current commercial p...

After reviewing some of the basic concepts, nomenclatures and parametrizations of Astronomy, Astrophysics and Cosmology, we introduce a few central problems in Nuclear Astrophysics, including the hot-CNO cycle, helium burning and solar neutrino’s. We demonstrate that Secondary (Radioactive) Nuclear Beams allow for considerable progress on these problems.
