This article translates some recent results on quasilocal horizons into the language of (3 + 1) general relativity so as to make them more useful to numerical relativists. In particular quantities are described which characterize how quickly an apparent horizon is evolving and how close it is to either equilibrium or extremality.

A wide variety of heavy vehicle types—including single-unit trucks, combination trucks with one, two, or three trailers, and buses—operate on U.S. highways. These heavy vehicle types each have unique physical and performance characteristics that interact with highway features. This chapter summarizes the physical and performance characteristics of heavy vehicles. The issues addressed in this ch...

Anthropometrie measures Body mass index When we speak about the prevalence of obesity in populations, we mean the fraction of people who have excess storage of body fat. ln adult men with weight in the acceptable range, the percentage of body fat is around 15-20%. ln women, this percentage is higher (about 25-30%). Because differences in weight between individuals are only partly due to variati...

The Salton Sea of California lying below sea level in a dcscrt basin, serves as a sump for irrigation water diverted from the Colorado River. The present Sea reached its maximum size and highest surface elevation at the time of its formation in 1907. Due to evaporation at the rate of six feet per year the surface elevation fell from -195 feet to its minimum of -240 feet in 1948, the surface are...

Computer media develop progressively day by day. In the process of designing architecture, the employment of digital model seems to become more significant while the traditional physical model have still been used. However, the physical model had some unique characteristics which digital one has not. And those characteristics were what we intended to discover and put into the digital modeling e...

Borna disease virus (BDV) is a nonsegmented negativestrand ribonucleic acid (RNA) virus that is unique among viruses of the order Mononegavirales in its genomic organisation, nuclear localisation for replication and transcription, splicing and neurotropism. Most reports of natural infection have described outbreaks in horses and sheep in central Europe; however, the virus appears to be distribu...
