Assessment of heavy metals pollution indices in sediments of Tiyab and Kolahi International Wetlands

Heavy metals are pollutants from multiple man-made or natural sources which directly or indirectly enter bodies of water. Therefore, investigation of deposits as metal contaminants is important. The international wetlands of Tiyab and Kolahi are among the most important ecosystems in the south of Iran that due to development programs are polluted by different sources. In order to identify envir...

Silicon Auditory Processors as Computer

Several research groups are implementing analog integrated circuit models of biological auditory processing. The outputs of these circuit models have taken several forms, including video format for monitor display 1,2], simple scanned output for oscilloscope display 3], and parallel analog outputs suitable for data-acquisition systems 4]. In this paper, we describe an alternative output method ...

Virtual Processors as Kernel Interface

After virtualization has gained traction in a variety of fields ranging from the desktop computer to datacenter servers, it is likely to make inroads into embedded systems as well. The complexity of a VM implementation depends on the virtualization abilities of the processor used. Unfortunately, the instruction set architecture of many popular embedded CPUs is not virtualizable, which precludes...

Use of Constructed Wetlands in Water Pollution Control: Historical Development, Present Status, and Future Perspectives

During the last two decades the multiple functions and values of wetlands have been recognized not only by the scientists and managers working with wetlands, but also by the public. The ability of wetlands to transform and store organic matter has been exploited in constructed wetlands. This paper summarizes the state-of-the-art of the uses of constructed wetlands in water pollution control by ...
