Distributed sensor networks operating through wireless communication offer a powerful means to sense, analyze and respond to dynamic environments spread over vast areas. Latest developments in micro electro mechanical sensors (MEMS) and related devices offer several technical and operational advantages making distributed sensor networks as a viable approach. Robustly packaged, inexpensive, ener...

With the remarkable increase of genomic sequence data of microorganisms, novel tools are needed for comprehensive analyses of the big sequence data available. The self-organizing map (SOM) is an effective tool for clustering and visualizing high-dimensional data, such as oligonucleotide composition on one map. By modifying the conventional SOM, we developed batch-learning SOM (BLSOM), which all...

Biopiling is an ex situ bioremediation technology that has been extensively used for remediating a wide range of petrochemical contaminants in soils. Biopiling involves the assembling of contaminated soils into piles and stimulating the biodegrading activity of microbial populations by creating near optimum growth conditions. Phytoremediation is another very successful bioremediation technique ...

Background: Tuberculosis (TB) is predominantly an airborne disease. However, quantitative and qualitative analysis of bio-aerosols containing the aetiological agent, Mycobacterium tuberculosis (Mtb), has proven very challenging. Our objective is to sample bio-aerosols from newly diagnosed TB patients for detection and enumeration of Mtb bacilli. Methods: We monitored each of 35 newly diagnosed,...

Emerging pollutants reach the environment from various anthropogenic sources and are distributed throughout environmental matrices. Although great advances have been made in the detection and analysis of trace pollutants during recent decades, due to the continued development and refinement of specific techniques, a wide array of undetected contaminants of emerging environmental concern need to...

It is believed that there is a close correlation between the physical and mental activities of human body. These physical activities can be measured using various multimodal bio-signals employing either invasive or non-invasive sensors. In contrast, although mental activities have been modeled from various standpoints, they have been associated mostly with brain activities. We have focused on m...

In recent years, the demand for the use of sustainable and eco-friendly environmental processes is rapidly growing subjected to economic, public, and legislation pressure. Biotechnology provides a plethora of opportunities for effectively addressing issues pertaining to the monitoring, assessment, modeling, and treatment of contaminated water, air, and solid waste streams. In this context, sour...

Air quality monitoring by using bio-indicator currently being promoted and frequently used in studies due to their advantages compared other scientific approaches. The of as a bio-monitoring air are, it remains the cheapest, most available simplest matrix for reliable atmospheric monitoring. This study was conducted determine moss ability be when expose different environments. Four environmenta...

Nowadays, there is a high demand for sensitive and selective real-time analytical methods suitable wide range of applications, from personalized telemedicine, drug discovery, food safety, quality control, to defense, security, as well environmental monitoring. Biosensors are devices able detect bio-chemical analytes (e.g., neurotransmitters, cancer biomarkers, bio-molecules, ions), through the ...
