Migrant housing and mobility patterns are affected by both the unique institutional factors related to migration and a common set of socio-economic characteristics shared by urban residents. China’s unprecedented waves of internal migration are accompanied by long-standing rural–urban and local–nonlocal divides that have been institutionalized through the household registration system. This pap...

An alternative in vitro approach to drug screening has been the use of human cell cultures for antiviral agents and microbial cell cultures for the assessment of the carcinogenic potential of selected compounds. A number of protozoan species have been also used as drug screens for anti-protozoal agents. The ciliated protozoan Tetrahymena pyriformis species has been widely utilised as a dru...

Spatial mobility is a topical concept of analytical migration science, which makes it possible to assess the desires, readiness and capabilities of the population to move over certain distances and time. In the management of spatial mobility assessment requires the organization of systematic monitoring, which includes identifying the mobility potential in spatial and temporal interpretation, th...

BACKGROUND The study analyzed correlations between selected variables in cervical derangement syndromes. MATERIAL AND METHODS We analyzed data from 63 patients regarding pain (VAS, McGill Pain Questionnaire), mobility (CROM goniometer), dizziness, nausea, the duration of the current episode, and the number of previous episodes (history). Student's t and chi(2) tests and Pearson's r correlatio...

Much is known about human walking, but it is not known how walking is used during typical activities. Since improving walking ability is a key goal in many surgical, pharmacological, and physiotherapeutic interventions, understanding typical community mobility demands regarding the length of walking bouts, the number of sequential steps frequently performed, and the duration of common nonwalkin...

Dynamics is an inherent characteristic of computational grids. The volatile nodal availablity requires grid applications and services be adaptive to changes of the underlying grid topology. Mobile execution allows mobile users or tasks to relocate across different nodes in the grid. This poses new challenges to resource access control. Resource sharing in the grid coalition environment creates ...

We have recorded time-resolved LII signals from a laminar ethylene diffusion flame over a wide range of laser fluences at 532 nm. We have performed these experiments using an injection-seeded NdYAG laser with a pulse duration of 7 ns. The beam was spatially filtered and imaged into the flame to provide a homogeneous spatial profile. These data were used to aid in the development of a model, whi...
