The important developments in industrial fermentation lead to the utilization of microbial enzymes in different applications. Selected organisms Aspergillus fumigatus, A. terreus, Penicillium chrysogenum, P. funiculosum and Fusarium moniliforme. Various environmental parameters like pH, temperature and nutritional parameters such as carbon and nitrogen sources were investigated to optimize the ...

The paper presents a multiobjective optimization approach to process parameter optimization in continuous casting of steel, which is the most widely used steel production process. The optimization task is to find parameter values such that the target values of the empirical metallurgical optimization criteria are approached as closely as possible, since this in turn results in high quality of t...

production of oxytetracycline by an isolated strain of streptomyces rimosus from iranian soil was investigated using a special fermentation medium. a comparative study was performed with standard strain ptcc 1144 using the following parameters optimum growth conditions with respect to time, ph, and different amounts of corn steep liquor. surprisingly, the production yield of the wild strain was...

theaim of the current study was to assess effects of different levels of origanum vulgare (0, 250, 500, 750 and 1000 mg/l) on kinetics of gas production, some ruminal digestion and fermentation parameters, methane production and also to determine its potential in controlling rumen acidosis using in vitro method in four separate phases. in the first phase, the asymptote of gas production (a) and...

Volatile esters are responsible for the fruity character of fermented beverages and thus constitute a vital group of aromatic compounds in beer and wine. Many fermentation parameters are known to affect volatile ester production. In order to obtain insight into the production of ethyl esters during fermentation, we investigated the influence of several fermentation variables. A higher level of ...

New maternal breeding values have been developed for use in UK beef evaluations. To undertake multitrait BLUP evaluations, it is necessary to have a full covariance matrix. This study outlines the approach taken to construct the full covariance matrices for the four beef breeds that most widely contribute to suckler beef cows in the United Kingdom. The maternal traits investigated were age at f...

Soft computing is a powerful tool that is suited to handle complex problems of modelling and optimisation. The relationships between fibres, production parameters and spinning results are such an example. The relationships can be modelled using neural networks, learning classifier systems and memory based learning. A comparison is made of these techniques with the traditional statistical regres...

A representation form of acoustic information in a trained phone library at the production parametric as well as the spectral level is described. The phones are trained in the parametric domain and are transformed to the spectral domain by means of a synthesis procedure. By this twofold description, potentially more powerful procedures for speaker adaptation and generation of unseen triphones c...
