The aim of the study is to examine the process of change with age of hard and total palate arching. Differences were compared in the arching of the hard and total palate in pairs of twins of the same sex and in pairs of twins of opposite sexes aged between 4 and 7 months of foetal life. On the basis of the results obtained it may be stated that: 1. There is some delay in the process of developm...
Variations in the origin of arteries in the abdomen are very common but with the invention of new operative techniques within the abdominal cavity, the anatomy of abdominal vessels has assumed much more clinical importance. During routine dissection of the abdominal cavity, we came across multiple arterial anomalies involving testicular and suprarenal arteries. On the right side, there was doub...
We present in this paper the behavior of an artificial agent who is a member of a crowd. The behavior is based on the social comparison theory, as well as the trajectory mapping towards an agent’s goal considering the agent’s field of vision. The crowd of artificial agents were able to exhibit arching, clogging, and bursty exit rates. We were also able to observe a new phenomenon we called doub...
In the current paper results of a well instrumented experimental procedure for studying the arching effect in loose and dense sand are presented. The apparatus comprises concentric circular trapdoors with different diameters that can yield downward while stresses and deformations are recorded simultaneously. As the trapdoor starts to yield, the whole soil mass deforms elastically. However, afte...
Experimental and numerical tests of the trap-door problem have been carried out, involving several granular materials. Three phases have been observed in the load transfer mechanism, as the trap-door is moved downward. The classical pattern for the description of this type of problem (a vertical plane of failure at each edge of the trap-door) corresponds to the third phase observed. The previou...
