    Notes: Abstract Multibody Dynamics and Object Oriented Programming are both leading technologies in their fields. This research combines them to produce a general purpose multibody dynamics code which is robust and easy to maintain. The simulator permits creation of mechanical systems from information specifying the properties and locations of parts, joints, springs, dampers, forces, gravity, etc. The mechanical components of the system are mirrored by software objects which interact to automatically assemble and integrate the equations of motion. This paper presents a multibody dynamics formulation suitable for object oriented programming, the principles of OOP and the procedures to create software objects with specific behaviors to represent parts, joints, forces springs, dampers etc. The aim is to demonstrate the use of OOP in serious engineering computing.

    Notes: Abstract  A new bacterium producing a novel transfructosylating enzyme was isolated from soil and designated as Bacillus macerans EG-6. Various culture conditions for enzyme production were optimized in a flask culture. 1% (w/v) sucrose as a carbon source and a mixed nitrogen source (1% yeast extract, 1% polypeptone, and 0.5% ammonium chloride) gave the best enzyme production. Addition of phosphate and magnesium ion into the medium enhanced the enzyme yield. Optimum culture pH and temperature were 7.0 and 37 °C, respectively. Under optimal culture conditions, transfructosylating enzyme was rapidly produced in the early growth period, thereafter invertase activity was predominant as the culture proceeded. Using the culture filtrate, production of fructooligosaccharides from sucrose was preliminarily carried out. In a low sucrose concentration (200 g/l), transfructosylating activity competes with invertase activity in sucrose utilization. Subsequently, low fructooligosaccharide yield (20%) was achieved due to liberation of high amounts of glucose and fructose. The best oligosaccharide yield (43%) was achieved when 500 g/l sucrose was utilized.

    Continuous production of inulo-oligosaccharides from chicory juice by immobilized endoinulinase (2000)

    Notes: Abstract Several carrier materials were examined for endoinulinase immobilization. A polystyrene carrier material (UF93®) gave the best immobilization capacity (217 units/g carrier) and operational stability. Carbohydrate compositions in the reaction product were quite similar irrespective of the support materials even though each carrier material has different pore structure associated with diffusional restriction. After immobilization the optimal pH for enzyme activity was shifted from 5.0 to 4.5, whereas optimal temperature (55 °C) was unaltered. Continuous production of inulo-oligosaccharides from chicory juice was carried out using the polystyrene-bound endoinulinase. The recommended operating conditions of the enzyme reactor for maximizing productivity were as follows: feed concentration, 100 g/l chicory juice; flow rate, as superficial space velocity 2.0 h−1; temperature, 55 °C. The enzyme reactor was run for 28 days at 55 °C achieving an oligosaccharide yield of 82% without any significant loss of initial enzyme activity, where the volumetric productivity was 200 g/l · h. Furthermore, there was no marked difference in operational stability between the two reactors fed with pure inulin solution and with chicory juice as a substrate even though chicory juice contains a lot of impurities.
