Different multivariate statistical analysis such as, cluster analysis, principal component analysis, and multidimensional scale plot were employed to evaluate the trophic status of water quality for four monitoring stations. The present study was carried out to determine the physicochemical parameters of water and sediment characteristics of Pondicherry mangroves-southeast coast of India, durin...

As part of a joint Sino-U.S. research project to study the deep structure of the Tibetan plateau, 11 broadband digital seismic recorders were deployed on the plateau for one year of passive seismic recording. In this report we use teleseimic P waveforms to study the seismic velocity structure of crust and upper mantle under three stations by receiver function inversion. The receiver function is...

[1] We utilize seismic converted phases on more than 700 receiver functions calculated for 42 stations in the South Island, New Zealand, to infer crustal and uppermost mantle structure. We determine the crustal thickness from direct observations of conversion from the Moho interface and infer zone of the maximum thickness being located along the axis of the Southern Alps, just east from the Alp...

In this study, we analyze regional seismograms to obtain the crustal structure in the eastern Great Basin and western Colorado plateau. Adopting a forward-modeling approach, we develop a genetic algorithm (GA) based parameter search technique to constrain the one-dimensional crustal structure in these regions. The data are broadband three-component seismograms recorded at the 1994-95 IRIS PASSC...

The Tucunduba Dam is about 290 km West of Fortaleza, Ceará state. The seismic monitoring of the area, with a local network, has began on June 11, 1997, soon after the occurrence of the event with magnitude 3.2 mb on June 09, 1997. The monitoring was done with one the analogical station (used for magnitude duration measurement and statistical control activity) and seven digital stations. The dig...

In this study, a novel model that performs ensemble empirical mode decomposition (EEMD) and stepwise regression was developed to forecast the water level of tidal river. Unlike more complex hydrological models, main advantage proposed is only required data are data. EEMD used decompose signals from river into several intrinsic functions (IMFs). These IMFs then reconstruct ocean stream component...

OBJECTIVES The purpose of this research was to measure fever prevalence and the effectiveness of a fever screening procedure in detecting febrile arrivals at an international airport in Korea. METHODS Data were retrieved from arrivals' health declaration forms and questionnaires for febrile arrivals at an international airport collected by a national quarantine station during the year 2012. S...

METHODS The Centers for Disease Control and Prevention and the Association of State and Territorial Health Officials selected 17 state and large local jurisdictions on the basis of their proximity to federal quarantine stations and collaborated with their state health department legal counsel to conduct formulaic self-assessments of social distancing legal authorities, create tables of authorit...
