Mechanical instability of monocrystalline and polycrystalline methane hydrates
Despite observations of massive methane release and geohazards associated with gas hydrate instability in nature, as well as ductile flow accompanying hydrate dissociation in artificial polycrystalline methane hydrates in the laboratory, the destabilising mechanisms of gas hydrates under deformation and their grain-boundary structures have not yet been elucidated at the molecular level. Here we...
متن کاملEstimating Efficiency of Monocrystalline and Polycrystalline Photovoltaic Panels Using Neural Network Models
The energy production analysis of a photovoltaic system depends on the panels tempreture and solar radiation. An endless and free source of solar energy received at the Earth's surface depends on the geographical location, different hours of day and seasons of the year.Hence, its correct evaluation is a strategic factor for the feasibility of a solar system. in this paper, a new method of ener...
متن کاملExperimental Study of Positron Production from Monocrystalline Targets at the Kekb Injector Linac
We report a series of positron-production experiments from an axially-oriented single-crystal target by 4and 8GeV channeling electrons at the KEKB injector linac. The targets tested are tungsten crystals with different thicknesses (14.2 mm at maximum), and diamond crystals with two different thicknesses (7.25 mm at maximum). The axis <111> for the tungsten crystals and that <110> for the diamon...
متن کاملIn vitro study of color stability of polycrystalline and monocrystalline ceramic brackets
OBJECTIVE The aim of this in vitro study was to analyze color stability of monocrystalline and polycrystalline ceramic brackets after immersion in dye solutions. METHODS Seven ceramic brackets of four commercial brands were tested: Two monocrystalline and two polycrystalline. The brackets were immersed in four dye solutions (coffee, red wine, Coke and black tea) and in artificial saliva for t...
متن کاملmolecular and physiological characterizations of floral scent production in rosa damascena mill.
گل محمدی (r. damascena mill.)مهمترین گونه ای است که در تولید گلاب، عطر و اسانس، در صنعت عطرسازی و دارویی کاربرد دارد. با وجود اهمیت عطر گل محمدی، پژوهش های مولکولی و بیوشیمیایی عطر گل این گونه هنوز در مراحل ابتدایی است. در این پژوهش، ویژگی های مولکولی و فیزیولوژیکی تولید عطر در گل محمدی در آزمایش های مختلف مورد بررسی قرار گرفتند. در آزمایش اول، پژوهشی به منظور بررسی تنوع شیمیایی اسانس میان 44 ت...
