• Direct comparison between air-cooled string and water-cooled string. Thermal contact with water increases yield 5–6%. model derived to include both air temperature. Performance data thermal predict U-value of 70–80 W/m 2 K for membrane FPV. For based FPV systems, temp needed when estimating module temp. Enhanced performance floating PV due cooling is widely claimed, but poorly quantified docu...

Simulated adsorption isotherms for water in UiO-66 illustrate that defects in the form of missing linkers make this MOF more hydrophilic. Heats of adsorption and density plots further confirm the effect of defects on adsorption of water in UiO-66 at low loadings. In addition, water and CO2 isotherms indicate that not only the amount of defects but their locations within the material affect the ...

The role of leaf water relations in controlling cell expansion in leaves of water-stressed maize and barley depends on time scale. Sudden changes in leaf water status, induced by sudden changes in humidity, light and soil salinity, greatly affect leaf elongation rate, but often only transiently. With sufficiently large changes in salinity, leaf elongation rates are persistently reduced. When pl...

The Great Lakes Water Quality Agreement (GLWQA) may not be known by most people on either side of the US–Canadian border, but it is important. The International Joint Commission (IJC), the US– Canadian body that advises both governments on issues around the boundary waters is also an important organization, but not well known. The article by Gilbertson and Watterson raises questions about the p...

We have devised a novel importance sampling method for nonequilibrium processes. Like transition path sampling, the method employs a Monte Carlo procedure to confine or bias the search through trajectory space. In this way, molecular dynamics trajectories consistent with the nonequilibrium dynamics of interest are generated efficiently. Using results of this sampling, we demonstrate that statis...

Ku Molecular dynamics (MD) simulations are mostly performed using non-polarizable force fields. This approximation works in homogeneous systems but there are situations – such as pores, cavities and interfaces – where an ...

This paper describes a study conducted to develop a method to facilitate more reliable determination of the rehabilitation priority order for water pipes by taking into account the pipes’ hydraulic importance. Existing methods use only the pipeline deterioration rate to determine the rehabilitation priority order. Accordingly, the deterioration rate under normal conditions and the hydraulic imp...
