VUV/UV light inducing accelerated phenol degradation with a low electric input

Juan Kiwi, Mengkai Li

This study presents the first evidence for the accelerated degradation of phenol by Fenton's reagent in a minifluidic VUV/UV photoreaction system (MVPS). A low-pressure mercury lamp used in the MVPS led to a complete degradation of phenol within 4-6 min. T ...

Control of pulsed light propagation through multimode optical fibers

Edgar Emilio Morales Delgado

Visualization of organs and cells in the interior of living beings is a challenging task due to the light absorption and multiple light scattering occurring in biological tissue that prevents the di-rect transmission of images. A standard visualization app ...

Experiments on the effect of inflow and outflow sequences on suspended sediment exchange rates

Anton Schleiss, Giovanni De Cesare, Michael Müller

In laboratory experiments, the influence of inflow and outflow sequences on the behavior of fine sediment was investigated. The experimental set-up consisted of two interconnected rectangular basins, between which water was moved back and forth. Suspended ...

Head losses and influence length of sharp-edged and rounded orifices under steady flow conditions

Anton Schleiss, Giovanni De Cesare, Nicolas Jean François Pascal Ghislain Adam

Orifices have been largely studied either for flow metering or for producing head losses. An orifice which is used as a flow meter is well defined in ISO 5167. All the geometrical parameters are defined to obtain discharges as accurate as possible. However ...

High light intensity mediates a shift from allochthonous to autochthonous carbon use in phototrophic stream biofilms

Tom Ian Battin, Amber Joy Ulseth

Changes in the riparian vegetation along stream channels, diurnal light availability, and longitudinal fluctuations in the local light regime in streams influence primary production and carbon (C) cycling in benthic stream biofilms. To investigate the infl ...

Effects of Lateral and Vertical Constrictions on Flow in Rough Steep Channels with Bedload

Anton Schleiss, Mário Jorge Rodrigues Pereira Da Franca, Sebastian Schwindt

Two-phase flows occurring at flow constrictions such as bridges or open sediment check dams are complex, especially for steep rivers with bedload transport. Dangerous bedload deposition and backwater effects may occur in steep mountain rivers at bridges. I ...

Quantification of Total N-Nitrosamine Concentrations in Aqueous Samples via UV-Photolysis and Chemiluminescence Detection of Nitric Oxide

Urs von Gunten, Florian Frédéric Vincent Breider

N-Nitrosamines are potent mutagens and carcinogens that can be formed during oxidative water treatment. This study describes a novel method for the determination of total N-nitrosamines by UV-photolysis and subsequent chemiluminescence detection of nitric ...

Hydraulic performance of stepped spillway aerators and related downstream flow features

Stéphane Christian Olivier Terrier

Roller compacted concrete gravity dams are built since several decades. In combination with such dams, stepped spillways are very often used as efficient flood release structures. More recently stepped spillways are also excavated into rock along the abutm ...

Experimental assessment of head losses through elliptical and sharp-edged orifices

Anton Schleiss, Giovanni De Cesare, Nicolas Jean François Pascal Ghislain Adam

Due to the European electricity market liberalization and the appearance of other renewable electricity producers, an increase of installed peak power capacity is relevant to provide larger amount of electricity in a shorter turbine duration. When the disc ...
