The abilities of Silybum marianum cell culture to biotransform benzaldehyde to benzyl alcohol in three culture systems were compared. Callus cultures of Silybum marianum were established from seedlings, and healthy suspensions and immobilized cultures grown on the Murashige and Skoog medium. S. marianum cells were immobilized in both agar beads and fiber cotton ...

Currently, in Iran's banking system, non-repayment of facilities has become one of the biggest issues, and due to the lack of a proper system for proper allocation of facilities, they face a number of problems, including the problem of allocation of loans, the problem of failure to repay loans Of the central bank, or the amount of facilities increased from the amount of reimbursement. The solut...

background: chitin is an abundant natural polysaccharide found in fungi, algae, and exoskeleton of insects. several bacterial species are capable of utilizing chitin as their carbon source. these bacteria produce chitinases for degradation of chitin into n-acetyl-d-glucosamine. so far, regulation of the chitinase encoding genes has been studied in different bacterial species. among bacillus spe...

background: acanthamoeba-related disease have a poor prognosis according to many previous studies. thus researches regarding biochemical and molecular aspects of this organism are a high priority. to this end achieving high amount of amoebae in culture is the first step for such studies. the main aim of the present research was to address the usage of tyi-s-33 (tripticase, yeast extract, iron-s...

Background: The aim of this study was to establish a cell-free sequential culture system that can support high levels of in vitro embryo development and blastocyst formation from bovine zygotes. To this end, this investigation was carried out to evaluate the effects of glucose, serum and EDTA on bovine zygote in vitro development. Materials and Methods: Bovine presumptive zygotes were derived f...

This paper develops a genetic algorithm based multivariable system identification technique from plant step response data directly. Using this technique, globally optimised models for linear and nonlinear systems can be identified without the need of a differentiable cost function or linearly separable parameters. Results are validated against a benchmark identification problem and a laboratory...

Fractional order calculus is the general expansion of linear integerorder calculus and is considered as one of the novel topics for modelling dynamical systems in different applications. In this paper, the generalized state equation of the nonlinear two-terminal element which is called memristor is discussed in the fractional-order sense. The effect of the added fractional-order parameter on th...
