Fecal material entrained in New Orleans flood waters was pumped into the local environment. Violet Marsh received water pumped from St. Bernard Parish and the Lower Ninth Ward. Sediment core samples were collected from canals conducting water from these areas to pump stations and from locations within Violet Marsh. Viable indicator bacteria and fecal sterols were used to assess the levels of fe...

Emission spectra from a DC plasma discharge of nitrogen with a graphite cathode used for deposition of CNx layers were investigated in the visible range 350-900 nm. The spectra recorded at low and high resolution from both the negative glow and the positive column of the discharge were studied separately. All spectra are dominated by neutral and ionised N2 emission. In the positive column the v...

The diffuse far-ultraviolet (FUV) background has received considerable attention from astronomers since the 1970's. initial impetus came hope of detecting UV radiation hot intergalactic medium. central importance FUV to physics (heating and ionization) atomic phases motivated next generation experiments. consensus view is that emission at high latitudes three components: stellar reflected by du...

We have previously engineered green/red and red/far red photoreversible E. coli phytochrome and cyanobacteriochrome (CBCR) two-component systems (TCSs) and utilized them to program tailor-made gene expression signals for gene circuit characterization. Here, we transport the UV-violet/green photoreversible CBCR TCS UirS-UirR from Synechocystis PCC6803 to E. coli. We demonstrate that the promoter...

The PVSDM model was used for single and binary dye adsorption systems. This is commonly in systems, but this the first time a mixture of dyes literature. To that end, new adsorbent derived from Bauhinia forficata waste created described eventual use treatment combination (methylene blue crystal violet). isotherms revealed increasing temperature decreases methylene capacity while violet capacity...
