IJERPH, Vol. 8, Pages 3365-3379: Polycyclic Aromatic Hydrocarbons in Maternal and Umbilical Cord Blood from Pregnant Hispanic Women Living in Brownsville, Texas

17-Aug-2011 | Ken Sexton; Jennifer J. Salinas; Thomas J. McDonald; Rose M. Z. Gowen; Rebecca P. Miller; Joseph B. McCormick; Susan ..., International Journal of Environmental Research and Public Health, 2011

Venous blood was drawn from 35 pregnant Hispanic women living in Brownsville, Texas, and matched cord blood was collected at birth. Gas chromatography/mass spectrometry was used to measure concentrations of 55 individual PAHs or groups of PAHs. Results indicate that these women and their fetuses ...

Sensors, Vol. 11, Pages 8085-8114: Common Criteria Related Security Design Patterns for Intelligent Sensors—Knowledge Engineering-Based Implementation

17-Aug-2011 | Bialas, Andrzej, Sensors, 2011

Intelligent sensors experience security problems very similar to those inherent to other kinds of IT products or systems. The assurance for these products or systems creation methodologies, like Common Criteria (ISO/IEC 15408) can be used to improve the robustness of the sensor systems in high ...

Sensors, Vol. 11, Pages 8072-8084: Sensitivities of Key Parameters in the Preparation of Silver/Silver Chloride Electrodes Used in Harned Cell Measurements of pH

17-Aug-2011 | Paul J. Brewer; Daniela Stoica; Richard J. C. Brown, Sensors, 2011

A questionnaire was completed by fourteen world leading national metrology institutes to study the influence of several variables in the preparation of Ag/AgCl electrodes on the accuracy of Harned cell measurements of pH. The performance of each institute in the last decade has been assessed ...

Sensors, Vol. 11, Pages 8060-8071: A Microring Resonator Based Negative Permeability Metamaterial Sensor

17-Aug-2011 | Sun, Jun ; Huang, Ming ; Yang, Jing-Jing ; Li, Ting-Hua ; Lan, Yao-Zhong, Sensors, 2011

Metamaterials are artificial multifunctional materials that acquire their material properties from their structure, rather than inheriting them directly from the materials they are composed of, and they may provide novel tools to significantly enhance the sensitivity and resolution of sensors. In ...

IJERPH, Vol. 8, Pages 3351-3364: A Literature Review of Cost-Benefit Analyses for the Treatment of Alcohol Dependence

16-Aug-2011 | Svetlana Popova; Satya Mohapatra; Jayadeep Patra; Amy Duhig; Jürgen Rehm, International Journal of Environmental Research and Public Health, 2011

The purpose of this study was to conduct a literature review of cost-benefit studies on pharmacotherapy and psychotherapy treatments of alcohol dependence (AD). A literature search was performed in multiple electronic bibliographic databases. The search identified seven psychotherapy studies from ...

Entropy, Vol. 13, Pages 1481-1517: Thermodynamics of Thermoelectric Phenomena and Applications

15-Aug-2011 | Goupil, Christophe ; Seifert, Wolfgang ; Zabrocki, Knud ; Müller, Eckhart ; Snyder, G. Jeffrey, Entropy, 2011

Fifty years ago, the optimization of thermoelectric devices was analyzed by considering the relation between optimal performances and local entropy production. Entropy is produced by the irreversible processes in thermoelectric devices. If these processes could be eliminated, entropy production ...

IJERPH, Vol. 8, Pages 3318-3332: Design and Calibration of an Organic Diffusive Probe to Extend the Diffusion Gradient Technique to Organic Pollutants

15-Aug-2011 | Antonina Bondarenko; Daniela Sani; Maria Letizia Ruello, International Journal of Environmental Research and Public Health, 2011

The objective of this study was to develop a method for measuring the mobility of persistent organic pollutants in the solid phase of soils within the context of environmental pollution risk assessment. A new diffusive probe, purposely designed by adapting the diffusive gradient technique method, ...

Sensors, Vol. 11, Pages 8045-8059: Height Compensation Using Ground Inclination Estimation in Inertial Sensor-Based Pedestrian Navigation

15-Aug-2011 | Sang Kyeong Park; Young Soo Suh, Sensors, 2011

In an inertial sensor-based pedestrian navigation system, the position is estimated by double integrating external acceleration. A new algorithm is proposed to reduce z axis position (height) error. When a foot is on the ground, a foot angle is estimated using accelerometer output. Using a foot ...

Sensors, Vol. 11, Pages 8028-8044: A Noise-Aware Coding Scheme for Texture Classification

15-Aug-2011 | Mohammad Shoyaib; M. Abdullah-Al-Wadud; Oksam Chae, Sensors, 2011

Texture-based analysis of images is a very common and much discussed issue in the fields of computer vision and image processing. Several methods have already been proposed to codify texture micro-patterns (texlets) in images. Most of these methods perform well when a given image is noise-free, ...

Sensors, Vol. 11, Pages 8018-8027: Detection of Single-Nucleotide Polymorphism on uidA Gene of Escherichia coli by a Multiplexed Electrochemical DNA Biosensor with Oligonucleotide-Incorporated Nonfouling Surface

15-Aug-2011 | Gang Liu; Ruojun Lao; Li Xu; Qin Xu; Lanying Li; Min Zhang; Hao Shen; Sanjay Mathur; Chunhai Fan; Shiping Song, Sensors, 2011

We report here a practical application of a multiplexed electrochemical DNA sensor for highly specific single-nucleotide polymorphism (SNP) detection. In this work, a 16-electrode array was applied with an oligonucleotide-incorporated nonfouling surfaces (ONS) on each electrode for the resistance ...
