there is a new technique to measure total body water named bio-electrical impedance analysis (bia), used in healthy subjects and patients. bia determines the total body water (tbw), fat-free mass (ffm), body cell mass (bcm), extra cellular water (ecw), and intra cellular water (icw) in subjects without significant fluid and electrolyte imbalance. there are several methods such as segmental bia,...

Automated detection of chemical threats is essential for an early warning of a potential attack. Harnessing plants as bio-sensors allows for distributed sensing without a power supply. Monitoring the bio-sensors requires a specifically tailored hyperspectral system. Tobacco plants have been genetically engineered to de-green when a material of interest (e.g. zinc, TNT) is introduced to their im...

As part of MITRE’s work under the DARPA TIDES (Translingual Information Detection, Extraction and Summarization) program, we are preparing a series of demonstrations to showcase the TIDES Integrated Feasibility Experiment on Bio-Security (IFE-Bio). The current demonstration illustrates some of the resources that can be made available to analysts tasked with monitoring infectious disease outbrea...

Surface plasmon resonance (SPR) imaging sensors realize label free, real-time, highly sensitive, quantitative, high throughput biological interaction monitoring and the binding profiles from multi-analytes further provide the binding kinetic parameters between different bio-molecules. In the past two decades, SPR imaging sensors found rapid increasing applications in fundamental biological stud...

In this paper, we present a new bio-impedance monitor for wearable and continuous monitoring applications. The system consumes less than 14.4mW when measuring impedance, and 0.9mW when idling. Its compact size (4.8cm × 3cm × 2cm) makes it suitable for portable and wearable use. The proposed system has an accuracy of 0.5Ω and resolution of 0.2Ω on both resistance (R) and reactance (X) measuremen...

Aquifer microbial communities can be investigated using Bio-traps(®) ("bio-traps"), passive samplers containing Bio-Sep(®) beads ("bio-beads") that are deployed in monitoring wells to be colonized by bacteria delivered via groundwater flow through the well. When bio-beads are "baited" with organic contaminants enriched in (13)C, stable isotope probing allows assessment of the composition and ac...

The purpose of this paper is to analyze the biological mutational effects caused by low doses of ionizing radiation in biological samples placed close to and around deposits of radioactive waste, as a way of monitoring the environment close to these deposits. In order to do this the Tradescantia pallida, was chosen, and through micronuclei tests one could verify the sensitivity of the dose/ Res...

Remote sensing technology is very useful in getting synoptic estimates of grass bio-parameters which is important for rangeland monitoring . The retrieval of bio-parameters is usually realized by developing empirical regression formula. However, it is less convincing if the regression line is built on limited observations from one growth stage . In this research, three field surveys were carrie...

pesticides are one of the most pollutants in aquatic ecosystems. monitoring of aquatic pollution with these compounds is very important. therefore, health status of aquatic animals can be used as a bio-indicator for pollution monitoring in surface waters. diazinon is an organophosphorous pesticide, which is found in the aquatic environment of iran. the concern has arisen over the ability of thi...
