This paper deals with the construction and control of a turtle-like underwater robot with four mechanical flippers. Each flipper consists of two joints generating a rowing motion by a combination of lead-lag and feathering motions. With cooperative movements of four flippers, the robot can propel and maneuver in any direction without rotation of its main body and execute complicated three-dimen...

The conversion of a live chicken into safe and wholesome meat products suitable for human consumption takes place in a series of processing steps. Few of the processes require force to carry it out successively among which are slaughtering and de-feathering. The latter is the focus in this paper, plucking force of chicken produced from two breeds of chicken. Each sample of the chicken carcass w...

ID: 7461 Title: Multileaf Collimator (MLC) for Field Matching Photon field matching at the beam isocenter using independent jaws is the method of choice in many radiation treatments that require abutted fields. This study evaluated the suitability of using Multileaf Collimator (MLC) for such matching. The study employed a treatment planning system to model the field matching and the modeling wa...

In craniospinal irradiation, field matching is very sensitive to intrafraction positional uncertainties in cranio-caudal direction, which could lead severe overdoses/underdoses inside the planning target volume. During last decade, significant efforts were made develop volumetric-modulated arc therapy strategies, less setup uncertainties. this study, a treatment system-integrated method, named ...

Dietary T-2 toxin (0, 1, 2, 4, 8, and 16 mug./g.) was fed to 4 groups of 10 chickens at each treatment level from hatching until 3 weeks of age. Growth inhibitory levels (4, 8, and 16 mug./g.) caused abnormal feathering which appeared dose related. The chickens were sparsely covered with short feathers protruding at odd angles in comparison to controls. There were few feathers on the base of th...
