leprosy is one of the oldest diseases of the country and may have been brought over to this country from egypt in ancient times. leprosy is mose frequent in the province of tehran, east azarbaijan, guilan and mazandaran (43 per km2) than other part of the country (13-18 per km2).the incidence of leprosy is recorded at 7.7 per thousand and 35.2 per thousand in the southern and northern part of t...

background: micropatterning is becoming a powerful tool for studying cells in vitro. this method not only uses very small amount of material but also mimic the microenvironment structure present in living tissues better than flask culturing techniques. in previous studies using micropatterning of extracellular matrix proteins on glass surfaces, the rate of protein detachment from the surface wa...

In this paper, we considered the half logistic model and derived a probability density function that generalized it. The cumulative distribution function, the $n^{th}$ moment, the median, the mode and the 100$k$-percentage points of the generalized distribution were established. Estimation of the parameters of the distribution through maximum likelihood method was accomplished with the aid of c...

objective: serum leptin concentration reflects the body fat mass. there is controversial reports about the insulin effect on serum leptin concentration. we wanted to examine the effect of insulin therapy on serum leptin in children with new onset type i diabetes. materials and methods: this was a cross-sectional study in children's medical center on 34 children who had new onset type i dia...

Both radiative and nonradiative processes which occur in the active region of GaInAs–GaInAsP–InP asymmetric multiple quantum-well (AMQW) heterolasers with two quantum wells of different width (4 and 9 nm) are described. Several possible processes of non-radiative Auger recombination which affect the temperature sensitivity of the lasing threshold are analyzed and the temperature dependencies of...

We report in this review on the electronic continuum states of semiconductor Quantum Wells and Quantum Dots and highlight the decisive part played by the virtual bound states in the optical properties of these structures. The two particles continuum states of Quantum Dots control the deco-herence of the excited electron – hole states. The part played by Auger scattering in Quantum Dots is also ...

Parallel (P) and antiparallel (AP) configurations are widely applied in magnetic heterostructures have significant impacts on the spin-wave transmission magnonic devices. In present study, a theoretical investigation was conducted into of exchange-dominated spin waves with nanoscale wavelengths type heterostructure including two media, which magnetization state can be set to P configuration by ...
