The preceding DIN 6800-2 (1997) protocol has been revised by a German task group and its latest version was published in March 2008 as the national standard dosimetry protocol DIN 6800-2 (2008 March). Since then, in Germany the determination of absorbed dose to water for high-energy photon and electron beams has to be performed according to this new German dosimetry protocol. The IAEA Code of P...

The water quality in Biscayne Bay has been significantly affected by past and continuing coastal and watershed development. The nutrient concentrations in the Bay have been dramatically changed by the conversion of natural creeks and sheet flow freshwater inputs to rapid and episodic canal inputs from the large and rapidly expanding Miami metropolitan area. This study is an evaluation of nutrie...

Symbioses between sponges and algae are abundant in the nutrient-poor waters of tropical reefs, yet very little is known of the nutritional interactions that may promote this abundance. We measured nitrogen flux between the sponge Haliclona cymiformis and its symbiotic partner, the rhodophyte Ceratodictyon spongiosum, and assessed the potential importance of this flux to the symbiosis. While th...

We studied dogs with unilateral papain-induced emphysema to answer two questions: (1) Do emphysema lung-apposed hemidiaphragm (DiE) and normal lung-apposed hemidiaphragm (DiN) have equal capacities for lowering lung surface pressure? and (2) Are side-to-side differences in intrathoracic pressure the result of unequal force outputs by DiE and DiN or are they caused by differences in their mechan...

There is an ancient and well-known Asian folk-tale that, in a version by the poet Rumi in Tales from the Masnavi, tells of four men who are asked to feel an elephant in a dark room and describe what they are sensing. Each of them touches just one part of the elephant, so they all reach different conclusions and think that they are in the presence of either a water-spout, a fan, a pillar, or a t...

Research on early speech production has often argued that children’s representations start out being holistic. They receive more phonological feature specifications in the course of development. In this talk, we will briefly review the arguments from early production for underspecified representations, and subsequently focus on two sets of perception studies, which both confirm the underspecifi...

Era informaţiei cuprinde, în general, trei mari perioade [1]: societatea informaţională, societatea cunoaşterii şi societatea conştiinţei. În istoria României pot fi desprinse câteva etape ale erei informaţiei: O etapă premergătoare, între anii 1940-1965, în care Tudor Tănăsescu a creat şcoala româ-nească de electronică [2], Victor Toma a creat primul calculator electronic românesc cu tuburi el...
