Vero cells were grown adherent to microcarriers (Cytodex 1; 3 g L(-1)) using animal component free media in stirred-tank type bioreactors. Different strategies for media refreshment, daily media replacement (semi-batch), continuous media replacement (perfusion) and recirculation of media, were compared with batch cultivation. Cell densities increased using a feed strategy from 1×10(6) cells mL(...

Studies on bench scale reactors packed with two different media matrix – Biopac media and Fugino spirals were undertaken to determine the performance at various organic loading rate (OLR) and on one day hydraulic retention time (HRT). Parboiled rice mill wastewater depicted a COD/BOD ratio of 1.6 indicating good degradable nature of the wastewater. Four different organic loadings of 0.8, 1.6, 2...

Many nervous systems contain rhythmically active subnetworks that interact despite oscillating at widely different frequencies. The stomatogastric nervous system of the crab Cancer borealis produces a rapid pyloric rhythm and a considerably slower gastric mill rhythm. We construct and analyze a conductance-based compartmental model to explore the activation of the gastric mill rhythm by the mod...

From the end of 19th century to beginning 20th century, American feminism stirred a renew power in plosive era. In this era, people inevitably associate it with media. This paper introduces historical developments media, combining movies’ influences about feminine right and feminist movement analyze changing trend global right, positions. utilizes several classical typical America movies from c...

A lung function study was carried out to determine the relative effect of rice husk and saw dust on mill workers. The study consisted of 195 subjects of which 56 rice mill workers, 71 saw mill workers and 68 controls of similar age, sex and socio-economic condition. FVC was significantly reduced in saw-mill workers compared to both the controls and rice mill workers. Both FEV1 and PEFR/min were...

The stirred wet milling of aluminum-doped TiO 2 was considered. At speeds 2500–6000 rpm, the pH i.e.p. shifted from 5.7 to ~8, while at 8000 rpm shift in smaller. Milling reduced performance attributed a change predominant mechanism. XPS revealed an approximate linear correlation between relative surface alumina content (at.%) and particle specific area, with shifting corresponding alumina. low...

In this work, a blend of Ti, Nb, and Mn powders, with nominal composition 15 wt.% Mn, balanced Ti Nb wt.%, was selected to be mechanically alloyed by the following two alternative high-energy milling devices: vibratory 8000D mixer/mill® PM400 Retsch® planetary ball mill. Two ball-to-powder ratio (BPR) conditions (10:1 20:1) were applied, study evolution synthesized phases under each mechanical ...
