Background: Enzymatic corn wet milling (E-milling) is a process derived from conventional wet milling for the recovery and purification of starch and co-products using proteases to eliminate the need for sulfites and decrease the steeping time. In 2006, the total starch production in USA by conventional wet milling equaled 23 billion kilograms, including modified starches and starches used for ...

BACKGROUND Fine milling of dry lignocellulosic biomass, without prior chemical pretreatment, can produce a high percent theoretical yield of sugars during subsequent enzymatic saccharification. However, the high sugar yields, necessary for a commercial biofuels process, are costly, with the milling energy input, necessary to achieve such yields even exceeding the energy content of the biomass. ...

In this paper the concept and first evaluation of the control principle of the MicroAssistant is presented. The MicroAssistant is an interactive surgical robot system to support the surgeon in microsurgical interventions especially in middle ear surgery. During those interventions the surgeon is often confronted with very small and sensitive structures. This fact conflicts with the exhausting m...

one of the disadvantages of conventional milling tools is to produce a large amount of heat in cutting zone and so making the tool warmer. as a result, the tool would be worn and its life time would be reduced. therefore, in long time machining, it is essential to change inserts and tools, continiously. a milling tool with self rotary cutting inserts was designed and manufactured that enables i...

Compared with the conventional drilling, helical milling has obvious advantages in making holes of carbon fiber-reinforced plastic (CFRP). Nevertheless, rapid wear cutting edges readily causes some defects outlet holes, such as burrs and tearing. In order to improve hole-making quality CFRP, a comparative experimental study on ultrasonic-assisted bi-directional CFRP was carried out. The mechani...

Abstract The axis of rotation the tool is perpendicular for machined surface in case face milling technology. This technology applicable manufacturing planar surfaces. It can be feasible by conventional or computer numerical controlled (CNC) machines. aim this study analysis different settings that cause arc contacts. applied parameters are same except position changed comparison with workpiece...
