the objective of this research was to investigate the influence of the over-expression of recombinant interferon-g during high cell density cultivation on cellular characteristics of recombinant e. coli. batch and fed-batch culture techniques were employed to grow escherichia coli bl21 for production of human gamma-interferon in pet expression system. final cell densities in batch and fed-batch...

LADA, EMILY KATE. A Wavelet-Based Procedure for Steady-State Simulation Output Analysis. (Under the direction of Dr. James R. Wilson.) The objective of this research is to develop an automated sequential procedure by which an asymptotically valid confidence interval is constructed for the steady-state mean of a simulation output process. This procedure, called WASSP, determines a batch size and...

Semiconductor memories have, since 1970, been a significant factor in data storage. This has been especially true in Random Access memories and is becoming true of the slower serial access memories. The manufacture of semiconductor memories takes place in two stages; the batch manufacture of the dice as wafers and the piece-by-piece assembly of the good dice into packages. It is the batch manuf...

introduction: note taking while attending a ppt requires high activity of memory and writing process which ultimately leads to what is called “death by power point” referring to boredom and fatigue. to overcome this we planned to evaluate the impact of utilisation of uncompleted handouts given prior to ppt presentations. methods: final year mbbs students were divided in 2 batches, batch a and b...

This document defines a MIME content type suitable for tunneling an ESMTP [RFC-821, RFC-1869] transaction through any MIME-capable transport. This type can be used for a variety of purposes, including: Extending end-to-end MIME-based security services (e.g., [RFC-1847]) to cover message envelope information as well as message content. Making it possible to use specific SMTP extensions such as N...

This paper presents a comparison between batch and three different sets of fed batch fermentations forrhamnolipid production by Pseudomonas aeruginosa. The batch run was performed with 500 ml of culturemedium having the initial glycerol and sodium nitrate concentrations of 30 and 8.3 g/l, respectively. For a fedbatch run with nitrogen source in feed, 250 ml of the nitrogen exc...

the objective of this meta-analysis was to compare effects of chemical methanogenic inhibitors on fermentation parameters in ruminal batch cultures. nine published in vitro studies including 26 treatment means in which 2-bromoethane sulfonate, bromochloromethane and 9,10-anthraquinone were used as methanogens inhibitor compared in amount of ch4, h2, total volatile fatty acid, actate, propionate...

Motivated by applications in porcelain-making companies, we consider a type of optimization problems for batch-processing operations. In production, single machine with fixed capacity is used to process jobs. Several jobs can be processed together if their total size no more than the capacity. Batch-position-based learning effects are considered because workers become skillful gradually after t...

Batch processes are commonly characterized by uneven trajectories due to the existence of batch-to-batch variations. The batch end-product quality is usually measured at the end of these uneven trajectories. It is necessary to align the time differences for both the measured trajectories and the batch end-product quality in order to implement statistical process monitoring and control schemes. ...

An integrated batch-to-batch control and within batch re-optimisation control strategy for batch processes using neural network models is presented in this paper. In order to overcome the difficulties in developing detailed mechanistic models, neural network models are developed from process operation data. Due to model-plant mismatches and unknown disturbances, the optimal control policy calcu...
