Recently, the precise cell separation method has great attentions in the bio-engineering research field with advancement of bio technology. In the present study, we separated the isotacho marker particles from the suspending particle mixture solution using isotachophoresis technique in the micro-channel. As a result, the particle migration velocity was increased proportional to the applied electric field strength.

Computer simulation (CS) is a powerful tool to model transport phenomena, including fluid flows motions corresponding for the momentum, mass and energy transfer. CS has been widely used to simulate the temperature distribution during thermal processing of foods. In this paper, the background of thermal processing of food and the fundamentals of developing CS models are discussed. It also provides an overview of the current CS modeling studies of thermal processing in solid, liquid and liquid-solid mixtures. It is expected that the incredible fast growth in the use of CS in the food and bioprocessing industry will encourage engineers to develop CS models with high computational powder for designing industry-scale thermal processing systems and understanding the combined effect of thermal and non-thermal processing.

The vibration that occurs when starting the agricultural tractor is raised more than double compared to the general situation. In this case, impulsive vibration make the machines life to be shortened, which can cause a drivers physical problems also. Therefore, in this paper, we have taken an effective way to reduce the impulsive vibration that occurs when starting a agricultural tractor. As a result, we confirmed that appling the anti-vibration pads and the high stiffness engine mounts is effective method to reduce the impulsive vibration.

Recently, the precise cell separation method has great attentions in the bio-engineering research field with advancement of bio technology. The separation technique is applied to recognize particular cell from the suspension solution by specifying fluorescence light on a target material. In the present study, we separated the marker particles from the suspending particle mixture solution using isotachophoresis technique in the micro-channel. As a result, isotachophoresis zones were clearly visualized as going downstream in the electric field. The particle migration velocity has proportional to the applied voltage.
