Cocoa butter was crystallized statically from the melt to various temperatures in the range of -20 to 26 °C and annealed for up to 45 days. During this period, the polymorphism of the solid state was monitored using differential scanning calorimetry and powder X-ray diffraction. Moreover, the microstructure of the materials was imaged using polarized light microscopy. Below -15 °C, a mixture of...

in this paper a comparative analysis of two poems entitled â« phoenix â» by nima and â«l’albatros â» by baudelaire will be done. it, initially, tries to investigate the symbolism used by these two poets. then a comparative analysis is made from structural and thematic points of view. by comparing and contrasting the potential similarities and differences in these poems, an attempt is made to ...

A one-parameter symplectic group {e}t∈R derives proper canonical transformations on a Boson Fock space. It has been known that the unitary operator Ut implementing such a proper canonical transformation gives a projective unitary representation of {e}t∈R and that Ut can be expressed as a normal-ordered form. We rigorously derive the self-adjoint operator ∆(Â) and a phase factor e i ∫ t 0 τ Â (s...
