We present results from computer simulation and mode-coupling theory of the glass transition for the nonequilibrium relaxation of stresses in a colloidal glass former after the cessation of shear flow. In the ideal glass, persistent residual stresses are found that depend on the flow history. The partial decay of stresses from the steady state to this residual stress is governed by the previous...

Many immersed boundary methods solve for surface stresses that impose the velocity boundary conditions on an immersed body. These surface stresses may contain spurious oscillations that make them ill-suited for representing the physical surface stresses on the body. Moreover, these inaccurate stresses often lead to unphysical oscillations in the history of integrated surface forces such as the ...

It is shown that computer simulations can qualitatively reproduce experiments , where a powder of cohesive, round, hard particles is periodically deformed at constant volume. Two types of initial configurations are considered: Uniaxially precompacted ballistic deposits and biaxially precompacted DLA-clusters. Both initial configurations had the same volume fraction, but due to the different pre...

fars province and the city of shiraz were important centers of medical sciences in ancient and medieval period. at present, also shiraz accommodates one of the most outstanding universities, as well as medical centers and hospitals both in iran and the middle east.1 in this regards, the research office for the history of persian medicine held a ceremony in shiraz to honor scholars in the field ...

hospitals have a long history throughout the history of medicine. first hospitals are originated from persia in ancient times in the sassanid dynasty (2nd to 6th century ad). after the advent of islam in persia (iran) in 637 ad, medical knowledge and also hospitals were ourished and advanced by persian scholars. shiraz azodi hospital and university was one of the important hospitals in persia....

majority of practical terms in ophthalmology were compiled firstly in muslims` medical dictionary. anatomical and pathological terms such as retina and cataract were improved in this lexicon. mohammad ghazi, in journal of azziae, has considered ophthalmology as an innovation which was firstly introduced by muslim arabs. their attempts promoted this science and retained it the best for a long ti...

although iran has a deep history about 10000 years, its role in development of science in general and medicine in particular is yet to be known. there are several factors responsible for this, namely the destruction of a good number of ancient persian manuscripts and books. furthermore, lack of interest found among contemporary researchers seems to add to this anonymity. one way to compensate f...
