In this paper the role of nanobiotechnology in the study of biological systems in water environment is presented. The functional nano-meter-scale structures in the cell such as genetic material, membranes, enzymes and molecular machines are decribed. The knowledge gained has applications in nanomedicine. Nanoparticles have practical applications in detection of water pollution and water purific...

With the upcoming widespread distribution of smart meters for electricity, gas and water consumption, new opportunities are closely linked to new privacy concerns. In this paper, we present protocols that can be used to privately compute aggregate measurements, allowing for fraudand leakage detection as well as statistical evaluation of meter measurements, without revealing any information abou...

An evaluation of a pulsed-eurrent resistance meter ("Shigometer®", Model No. 7950) for facilitating detection of decay was performed on wood blocks of giant sequoia heartwood and of white fir sapwood. As decay progressed over a 12-week incubation period, a trend of lower meter readings was obtained, confirming reported field measurements of other workers. Variability in meter readings in situat...

Next-generation sequencing of the V1-V2 and V3 variable regions of the 16S rRNA gene generated a total of 674,116 reads that described six distinct bacterial biofilm communities from both water meters and pipes. A high degree of reproducibility was demonstrated for the experimental and analytical work-flow by analyzing the communities present in parallel water meters, the rare occurrence of bio...

Nitrate concentrations of groundwater are increasing in residential areas. One probable cause is input of nitrogen fertilizers to maintain healthy turfgrass. This study was conducted to evaluate differences in nitrate concentrations in soil water between sites fertilized with chemical or organic fertilizer. To obtain nitrate concentrations leaching below turfgrass and evaluate the impact to gro...

Although parasequence and sequence are scale-independent terms, they are frequently applied only to specific scales of cycles. For example, meter-scale cycles are commonly assumed to be parasequences or PACs. In the Upper Ordovician Kope and Fairview Formations of northern Kentucky, we examined a succession of 50 meter-scale cycles that have been variously interpreted as deepening-upward, shall...
