The structure of the crust of a neutron star is completely determined by the experimentally measured nuclear masses up to a density of the order of 1011 g.cm−3. At higher densities, the composition of the crust still remains uncertain, mainly due to the presence of “free” superfluid neutrons which affect the properties of the nuclear “clusters”. After briefly reviewing calculations of the equil...

A volcanic crust may be produced as a result of magma ocean processes. Solidification of a magma ocean naturally produces a silicate mantle with denser layers near the surface, therefore unstable to gravitational overturn. The mantle is predicted to rapidly flow in the solid state to gravitational stability. Hot buoyant silicate mantle rising from depth will melt through depressurization and er...

Nucleosynthesis, on the surface of accreting neutron stars, produces a range of chemical elements. We perform molecular dynamics simulations of crystallization to see how this complex composition forms new neutron star crust. We find chemical separation, with the liquid ocean phase greatly enriched in low atomic number elements compared to the solid crust. This phase separation should change ma...

color is one of the indications of dignified god and is one of the specifications of human life that its implications is changed in different periods based on time and place conditions,psychological characteristics and social conditions .also it has an important role inpoetic descriptions that creates beautiful images.this matter is more apparent in poetry of abbassi age poets because of variou...

stand establishment in crusting soil is one of the main concerns in the production of crops with delicate seedlings such as cotton, onions and rape seed. crust breaking, maintaining soil moisture and adding chemical and organic amendments to soil are different methods to weaken soil strength and allow the shoots to emerge. these methods are not always successful because they depend on factors s...

the study area is located south of ghonabad in eastern iran. this area is situated between two major faults, darouneh to the north and dashtbyaz to the south. the movements of these faults cased major dislocation of this block. najmabad granodiorite to granite batholith is elongated trending east-west 2×8 km2. mineralization is associated with granite and monzonite. alteration zones are: propyl...

On examination, discrete 2to 3-mm perifollicular papules localized to the bilateral axillae ( fig. 1 ) and the pubic area were noted. The color of the papules ranged from flesh-colored to slightly hypopigmented. Additionally, her left axilla showed areas of superficial erosion, erythema and overlying honey-colored crust ( fig. 2 ). Of particular interest, the patient’s father was also examined ...
