Radio has always had communicative concern for its listeners. It is characterized by personal address, live ness and acoustic moods that reach audiences in a variety of listening situations. Radio’s communicative concern should be available for all citizens, but in fact there is rather bad reception for DAB and FM in cities due to narrow streets and other physical interference, and in addition ...
Background State-of-the-art medium and feed development has proven its potential for increasing bioprocess efficiency many times. By the application of such advanced chemically defined and animal component-free formulations, in combination with recent cell lines, the yield of mammalian cell cultures was pushed to the binary gram per liter level. In this work, the current progress in designing s...
It has been recognized for many years that informal communication is an important part of effective work and thus vitally important in organizations. However, research on informal dimensions of information systems is rare. In this paper, Fish et al.’s (1990) model that distinguishes characteristics of informal and formal dimensions of computer-mediated communication (CMC) is further developed. ...
The aim of the present work was to compare the efficacies and levels of selectivity of different culture-dependent and -independent methods for analyzing bifidobacteria in human stool samples. The three different culture media used here significantly differed from each other, particularly with regard to the recovery of Bifidobacterium adolescentis. Bifidobacterium medium failed to recover B. ad...
در این پایان نامه، کنترل نرو-فازی در پرنده هدایت پذیر از دور (پهپاد) استفاده شده است ابتدا در روش پیشنهادی اول، کنترل کننده نرو-فازی توسط مجموعه اطلاعات یک کنترل کننده pid به صورت off-line آموزش دیده است و در روش دوم یک کنترل کننده نرو-فازی on-line مبتنی بر شناسایی سیستم توسط شبکه عصبی rbf پیشنهاد شده است. سپس کاربرد این کنترل کننده در پهپاد بررسی شده است و مقایسه ای ما بین کنترل کننده های معمو...
three bacteria from a tobacco industry effluent and one from a sewage sample were isolated on a medium comprising of 1% tobacco powder as sole source of nutrients. bacteria isolated from the industrial waste water were identified as bacillus cereus, b. alvei and b. circulans. while, lactobacillus sp. was isolated from the sewage sample. the bacteria were optimized for various growth conditions ...
We propose a simple procedure for designing an integrated single-chip grating-based thin-film filter. A simulation from a rigorous coupled-wave analysis shows that structural adjustment based on the effective medium theory can achieve the desired integration without notable performance degradation. Our spectropolarimetric filter design maintains spectral filter characteristics, while its extinc...
