introduction: standard concentrations of antibiotics in culture media are thought to have no detectable toxic effects on the cultured cells. however, since antibiotics are biologically active substances, the possibility that they interfere to some extent with cellular processes occurring in the cultured cells can not always be totally excluded. this study, therefore, was conducted to assess whe...

silicon thin layers are deposited on glass substrates with the thickness of 103 nm, 147 nm and 197 nm. the layers are produced with electron gun evaporation method under ultra-high vacuum condition. the optical reectance and the transmittance of produced layers were measured by using spectrophotometer. the optical functions such as, real and imaginary part of refractive index, real and imaginar...

This project explores Chinese character font classification and transformation, which are the most important two steps in reconstructing weathered Chinese characters. For font classification, SIFT is first used to capture font features, and neural network is built in Keras with almost perfect results achieved. For font transformation, a convolutional neural network is implemented in Tensorflow,...

Multi-layer orthotropic finite cylindrical shells with a viscoelastic core in contact with fluids are gaining increasing importance in engineering. Vibrational control of these structures is essential at higher modes. In this study, an extended version of the wave propagation approach using first-order shear deformation theory of shell motion is employed to examine the free vibration of damped ...

during the history of iran after islam, the 9th /13th century, coinciding with the timurids reign in this land, can be considered as the thriving age of various branches of art such as painting, architecture, illumination, book ornament, and music. similarly, the prevalence and development of scripts such as nasta‘līq and ta‘līq in calligraphy, besides flourishing this art, caused it to establi...

twenty-four 35-day-old lambs were distributed to a completely randomized design with 3 treatments to study the effects of number of feeding buckets per pen on performance, haematology and behaviour indicators. treatments consisted of 8 (t1), 4 (t2) or 2 (t3) feeding buckets/pen (8 lambs/pen). during the experiment, concentrate was fed at 08:30 in individual feeders. daily dry matter intake (dmi...
