The objectives of this presentation are to discuss the clinical role of magnetic resonance (MR) in local and nodal staging of prostate cancer, and to show new developments. The clinical questions are how can we improve with new MR imaging (MRI) techniques: localization, local staging, targeted radiotherapy planning, and nodal staging? Accurate tumour localisation is important for detection of p...

Reconfigurability/tunability has become an essential feature of modern agile RF and future mm-wave apparatuses and systems for wireless communications, sensing and imaging. In the coming decades there will be a paradigm shift towards smart, cognitive and agile wireless sensing (including imaging) and communication systems. The use of mm-wave frequencies will lead to communications systems showi...

This experiment compared the effects of sand and straw bedding in free stalls on resting time, cleanliness, hock injuries, and hoof health of dairy cows and tested whether cow preferences for a bedding material depended on the familiarity with the material. A total of 52 dairy cows were kept either on straw bedded concrete stalls or sand stalls for at least 21 wk. The lying behavior was observe...

background: training teachers through educational programs are necessary for fulfilling health science teaching competencies, short-term workshop has variously reported as an influential training program. purpose: the purpose was to determine the effects of educational workshops on teaching performance of medical teachers. methods: a 29-item questionnaire containing demographic information, and...

compared to quartz sand, the shear behavior of carbonate sand differs in  appearance, origin, and kind. carbonate sand is found mainly in the northern coast of the persian gulf and the oman sea. in this research, a comparison is made between the shear behavior of carbonate sand retrieved from the eastern region of the chabahar port, located north of the oman sea, and quartz sand obtained from f...

We compare the deformation patterns produced by sand and a sand mica mixture (14:1 ratio of sand to mica by weight) while simulating basin fill in extension and inversion models to analyze the potential of the sand mica mixture for applications that require a strong elasto-frictional plastic analogue material in physical models. Sand and the sand mica mixture have nearly equal angles of interna...

There are several types of firing tests of cannonballs. In ground firing tests, cannonballs without gunpowder charged are fired against sand heap. When a cannonball collides into sand, the cannonball’s penetration depth, stress and sand temperature depend on the sand properties. Sand tends to become harder than before after plenty of cannonball firing. This is because kinetic energy of a cannon...

An algorithm for simulating wind-ripples and moving sand is extended by the detection of fixed objects. This permits us simulation and animation of sand interacting with objects like houses, highways, cactuses, etc. Sand is accumulated on the windward side of an obstacle and the sand relocation and wind-ripples formation is diminished on the leeward side. The wind shadow depends on the object’s...
