The dynamical equations describing the evolution of a physical system generally have a freedom in the choice of units, where different choices correspond to different physical systems that are described by the same equations. Since there are three basic physical units, of mass, length and time, there are up to three free parameters in such a rescaling of the units, N f 6 3. In Newtonian hydrody...

The Native American flute, a traditional ethnic wind instrument developed by indigenous Native American cultures, is enjoying a renaissance in various sectors of society. The instrument evolved from traditional uses in courtship (Black Hawk & Patterson, 1834; Burton, 1909), treatment of the sick (Densmore, 1936), ceremony (Gilman, 1908; Stacey, 1906), signaling (Densmore, 1929), legends (Delori...

Four experiments were conducted to assess whether or not rhesus macaques (Macaca mulatta) could represent the unperceived movements of a stimulus. Subjects were tested on 2 computerized tasks, HOLE (monkeys) and LASER (humans and monkeys), in which subjects needed to chase or shoot at, respectively, a moving target that either remained visible or became invisible for a portion of its path of mo...

Currently there are no cancer models that can accurately predict the clinical activity of a drug. Compounds are screened and optimized for anticancer activity in a series of in vitro and in vivo models, each of which has its own strengths and limitations. Organotypic models are three-dimensional in vitro representations of tumor microenvironment, which are more biologically relevant and technic...

Existing evidence seems to indicate that Muslims in Scotland have constructed hyphenated or hybrid identities that draw on religion, ethnicity and nationality. However, minor attention has been given to the differences in importance, meanings, and strengths of these identities, or the significance of their identity markers. Ethnic minority people can be identified with both their ethnic groups ...

abstract background: escherichia coli, known as a clinically significant bacteria, can cause a wide range of infections, including urinary tract infections (utis), blood stream infections (bsis), and can frequently be isolated from various clinical specimens. evaluation of antimicrobial resistant pattern is a necessary action, especially about such bacteria which are frequent and life threateni...

Settlement geography and cultural landscapes, two well-established themes of human geography, have taken on renewed importance in the study of the United States. The examination of regional cultural patterns, such as the distribution of Hispanics in the American Southwest, Germans in Texas, and Mormons in the Salt Lake Region are a few examples of the geographic research tradition. More recentl...

Cultural beliefs and attitudes have been identified as significant contributing factors in the development of eating disorders. Rates of these disorders appear to vary among different racial/ethnic and national groups, and they also change across time as cultures evolve. Eating disorders are, in fact, more prevalent within various cultural groups than previously recognized, both within American...
