I . The effects of 4-6 h of water immersion on the renal excretion of water and electrolytes were studied in thirteen normal male subjects in balance on a constant diet containing 150 mEq of Na and 100 mEq of K per day. Each subject was studied during a control period, consisting of quiet sitting, and during water immersion to the neck. 2. Immersion resulted in a natriuresis beginning within th...

In the final paper of the Graph Minors series N. Robertson and P. Seymour proved that graphs are well-quasi-ordered under the immersion ordering. A direct implication of this theorem is that each class of graphs that is closed under taking immersions can be fully characterized by forbidding a finite set of graphs (immersion obstruction set). However, as the proof of the well-quasi-ordering theo...

The effects of fluoride, which is present in different oral hygiene products, deserve more investigation because little is known about their impact on the surface of titanium, which is largely used in Implantology. This study evaluated the surface of commercially pure titanium (cpTi) after exposure to different concentrations of sodium fluoride (NaF). The hypothesis tested in this study was tha...

Immersion has been shown to be beneficial in a number of different application domains. We attempted to quantify the effect of immersion on 3D abstract data analysis. We developed a program to show users animated plasma flows in a CAVE [1] environment. Stereopsis and field of regard were varied in a user test involving flows around a sphere. Our results showed that the stereopsis helped users t...

Despite the ecological and increasing commercial significance of cephalopods worldwide, little attention has been paid to developing techniques that investigate the movement of early life-history stages. We evaluated the potential of mass-marking giant Australian cuttlefish Sepia apama hatchlings, via immersion of eggs in water enriched in 137Ba isotope. Eggs were immersed in several 137Ba conc...

Tele-Immersion is the merging of audio and video conferencing with collaborative virtual reality, datamining and significant computation systems. As TeleImmersion often involves distantly located participants all interacting with each other in real-time, it relies heavily on the quality of the underlying networks used to distribute information between participants. This paper presents our preli...

Significant improvement in the performance of capacitive microfabricated ultrasonic transducers is reported and the modifications which enable the progress are described. Air-coupled through-transmission of glass and steel at 2.3 MHz is demonstrated for the first time. Furthermore, a 20 pm step on a silicon wafer is detected with both amplitude and phase signals at 3 MHz. The same process used ...
