Five hundred million travelers enter the US yearly at a Port of Entry (POE) after an Immigration & Naturalization Service (INS) interview. We describe a general method for sampling from a flow, and summarize results from random reinspections of travelers at 20 POEs. Analyses reveal that 47 in 5614 travelers (0.8% ± 0.24%) were erroneously granted entry. Results suggest INS intercepts 9.3% to 16...

This study presents an innovative approach to the design of a road weather information monitoring system (RWIS) that optimally combines spatial data on weather-related road surface conditions with data on traffic volume over a state-wide road network. The optimization method minimizes the spatially averaged ordinary kriging variance of hazardous road surface condition (HRSC) frequencies. Since ...

The Çaygören Reservoir was sampled monthly from February 2007 to January 2009 at three stations to determine the relationships between the chlorophyll-a (Chl-a) dynamics and soluble reactive phosphorus (SRP), nitrate-nitrogen (NO3-N), ammonium-nitrogen (NH4-N), water discharge, water transparency, water temperature (T), specific conductance (SC) and pH. Thermal stratification occurred in the re...

The importance of knowing the water quality status with use macroinvertebrates diversity gives an establishment to proper practices prevent pollution in Surigao River, City, Philippines. Riparian, Channel, and Environmental Inventory were used describing vegetation three-sampling stations. occurrence was supported by selected physicochemical parameters, WQI, ASPT. RCE scores for three sampling ...

Background: The development of clinical expertise depends not only on abundant practice but also on guidance through good feedback. Clinical teachers can improve learners’ skills by providing specific, performancebased feedback. In Taiwan, evidence-based practice (EBP) education has been taught through workshops, hands-on practice and small group discussion. However, the impact of feedback in E...

Introduction: Leachate is a liquid coming out of accumulated wet wastes which contains several chemical and dangerous elements. Furthermore, it causes the aquatic ecosystem contamination. The purpose of this study is to give an indication of the effects of Tonekabon landfill on the surface water, so evaluating the amount of leachate polluting in surface waters was investigated. Materials and M...

Measurement of chlorophyll-a can be considered important to investigate the primary production of an ecosystem. This study aimed to investigate chlorophyll-a concentration, primary production and the factors affecting them in Shadegan Wetland located in Khouzestan Province - Iran. Sampling for measuring (NO3, PO4, BOD5, DO, pH, EC, salinity, temperature) was performed seasonally at five samplin...

16 priority polycyclic hydrocarbons were identified and determined quantitatively by gas chromatography-mass spectrometry method in bottom sediments of estuarine coast of Danube. Concentration of the sum of 16 polyarenes in bottom sediments ranged from 329.6 to 1093.3 μg/kg. The total B(a)Peqv, whose values at the stations of sampling ranged from 34.9 to 195.1 μg/kg, was determined to evaluate ...
