asthma is one of the fastest growing syndromes in many countries and is adding a huge cost to the health care system. increasing reports have linked airway infectious diseases to asthma. influenza is one of the most serious airway infectious diseases and in recent years there have been some serious influenza virus pandemics which caused increased fatality in numerous different populations. dive...

We have observed photocarrier transport behaviors in ${\mathrm{BiFeO}}_{3}/{\mathrm{La}}_{1\ensuremath{-}x}{\mathrm{Sr}}_{x}{\mathrm{MnO}}_{3}$ (BFO/LSMO) heterostructures by using time-resolved synchrotron x-ray magnetic circular dichroism reflectivity. The magnetization of LSMO layers was used as a probe photo-induced carrier dynamics the photovoltaic BFO layers. During demagnetization proces...

austenite is a semi-stable phase in most stainless steels that deforms to martensite under md30 and forms martensitetype ά and ε due to the deformation in the steels. since the distribution of strain induced martensite plays animportant role in achieving desired properties, the main objective of the present work is to model martensitedistribution of ά during cold rolling using finite element me...

Photo- and charge-carrier-induced ion migration is a major challenge when utilizing metal halide perovskite semiconductors for optoelectronic applications. For mixed iodide/bromide perovskites, the compositional instability due to light- or electrical bias induced phase-segregation restricts exploitation of entire bandgap range. Previous experimental theoretical work suggests that excited state...

the moist sample shrinks during drying and the non-uniformity shrinkage involves stresses in the body. the aim of the present work is simulating deformations and drying-induced stresses of carrot slice during a convective drying. the effect of shrinkage on the heat and mass transfer profiles were considered. non-constant physical and thermal properties were also incorporated in the model and th...

statement of the problem many diseases to be treated by dentists require drug therapy. lack of paying enough attention to principles of drug prescription can lead to problems such as unsuccessful treatment. on the other hand, the most important way to prevent such problems is paying enough attention to prescription of drugs materials and methods in this descriptive study, 260 prescriptions rand...
