Interest in the biodegradation mechanisms and environmental fate of polycyclic aromatic hydrocarbons (PAHs) is motivated by their ubiquitous distribution, their low bioavailability and high persistence in soil, and their potentially deleterious effect on h ...
Observations made from vertical moorings of thermistors and current meters are used to analyze the relative contribution of the entrainment of overlying water and the cold plumes convecting from the surface to the cascade of dense shelf waters down the sid ...

An encapsulation device, designed on the basis of the laminar jet break-up technique, is characterized for cell immobilization with different types of alginate. The principle of operation of the completely sterilizable encapsulator, together with technique ...
The intensity of water absorption in the region of the solar spectrum plays a dominant role in atmospheric energy balance and hence strongly influences climate. Significant controversy exists over how to model this absorption accurately. We report dipole m ...
The obtimisation of water networks in a deinking mill has been carried out using Mixed Integer Non Linear Programming. The objective function included the costs of water and chemical usage, and of piping retrofitting. The constraints were stream compositio ...
We report the filling kinetics of different liquids in nanofabricated capillaries with rectangular cross-section by capillary force. Three sets of channels with different geometry were employed for the experiments. The smallest dimension of the channel cro ...
Preschool children, aged 4 and 5 years, report different understandings of the phenomenon of plant reproduction. We use their ideas as a starting point in designing an electronic device that illustrates phases of plant growth in response to children's augm ...
The cyclic undecapeptide cyclosporin A (CsA) has a remarkable spectrum of diverse biological activities, including anti-inflammatory, antifungal, antiparasitic as well as immunosuppressive activities. However, the low water solubility of this drug is a ser ...
The dye coumarin 343 (C343) adsorbed on the surface of ZrO2 nanoparticles in aq. solns. was used to study the solvation dynamics close to these surfaces. The time-resolved Stokes shift was measured by femtosecond frequency-resolved upconversion. The absorp ...
Polypeptide secondary structure controls the dimensions of aggregates formed from a polybutadieneb-poly(L-glutamic acid) diblock copolymer after direct dissolution into water. The hydrodynamic radius (RH) of these aggregates (even at high NaCl concentratio ...
