Scramjet Engine Tests at Mach 4 and 6The heat-sink engine has been tested in a free-jet engine test facility simulating flight conditions of Mach 4 at 20 km altitude and Mach 6 at 25 km. In the Mach 4 test, successful ignition of the main fuel was achieved by the plasma torch igniters with pilot fuel injection. However, in the Mach 6 t

An industrial point of view on scramjet combustor designg propulsion (especially ramjet) up to the hypersonic speed. This work includes air intakes, scramjet facilities, scramjet combustor, new measurement techniques (in the scope of PREPHA program), others cycles (precooled air, Pulsed Detonation Wave Engine, …), new test facilities (such as the Adiabat

Detonation of the Gas Mixtures with Inert Solid Particlesicles of sand. We performed an analysis of numerical data and investigated the effect of particle concentration on the velocity of detonation of a mix. There was suggested to choose the value of pre-exponential factor in the equation for gas combustion kinetics, i.e., from the conditions of best coi

T. Fujimori,M. Murayama,J. Sato,H. Kobayashi,T. Niiokar, the edible portion of widely consumed fruits or their derived products represent a major dietary source of carotenoids for animals and humans. Therefore, these pigments are crucial compounds contributing to fruit aesthetic and nutritional quality but may also have protecting and ecophysiological

L. L. Zheng,K. N. C. Brayns for the etiology and management of obesity and obesity-related metabolic diseases are reviewed. Most studied carotenoids in this context are β-carotene, cryptoxanthin, astaxanthin and fucoxanthin, together with β-carotene-derived retinoids and some other apocarotenoids. Studies indicate an impact

A. Stoukov,M. Gorokhovski,D. Vandrommearotenoid content and composition are essential to ensure carotenoid feasibility in malnourished population of many countries around the world, which is critical to alleviate vitamin A deficiency and other health-related disorders. The pathway of carotenoid biosynthesis is currently well understood,

Goro Masuya,Nobuo Chinzei,Yoichiro Mikithophylls). These pigments are bound to proteins in the pigment-protein complexes of the thylakoid membrane (see Section 6.1.1), where they have a direct and essential role in photosynthesis (see Chapters 3 and 8). Small amounts of carotenoids may also be located in the plastid envelope (see Chapter
