Abstract Spherical AlN powders with micrometer size have attracted great attention owing to their good fluidity and dispersity. However, the industrial preparation methods usually require high temperature long soaking time, which lead cost limit wide application of products. Herein, nearly spherical particles average 2.5 µm were successfully synthesized via an in-situ combustion synthesis metho...

the dual fuel engines at part loads inevitably suffer from lower thermal efficiency and higher carbon monoxide and unburned fuel emission. this work is carried out to investigate combustion characteristics of a dual fuel (dieselgas) engine at part loads, using a single zone combustion model with detailed chemical kinetics for combustion of natural gas fuel. the authors developed software in whi...

we have analyzed paraffin sections from 55 patients with histologically confirmed hodgkin’s disease (hd) for the presence of epstein-barr virus (ebv) markers using in situ hybridization to detect the ebv-encoded rnas (ebers) and immunohistochemistry to identify latent membrane protein-1 (lmp1) expression. tissue specimens from 55 cases of hodgkin’s disease included 22-mixed cellularity (mc), 27...

purpose : to investigate the application of mitomycin-c 0.02% (mmc) in the photorefractive keratectomy (prk) procedure in correcting regressed myopia methods : eighteen eyes of 11 patients with a spherical equivalent (se) of less than -5 diopters (d) who had undergone laser in situ keratomileusis (lasik) more than 2 years before were operated on. at the end of the prk procedure, mmc was applied...

background:breast cancer remains the most common and second lethal cancer in females. her-2/neu is one of the most important amplified oncogene in breast cancer. the amplification of her-2 is correlated with decreased survival, metastasis, and early recurrence.  the amplification of her-2/neu gene and synthesis of the protein are reported in 10%-34% of breast cancer cases associated with tumor ...

background the incidence rate of gastric cancer in western countries has shown a remarkable decline in the recent years while it is still the most common cancer among males in iran. the proto-oncogene myc, located at 8q24.1, regulates almost 15% of human genes and is activated in 20% of all tumors. the amplification of myc and overexpression of its protein product are observed in 15 - 30% of ga...

in this study, doxycycline hyclate release behavior from in situ forming drug delivery systems investigated. these systems based on poly()lactide-co-glycolide)(50:50 dissolved in n-methyl-2-pyrrolidone that were evaluated in different concentrations. these systems are useful for local treatment of periodontal diseases. uv spectroscopy is used to determine drug concentration in release medium. a...
