Fibre optic distributed temperature sensing (DTS) is widely applied in Earth sciences. Many applications require a spatial resolution higher than that provided by the DTS instrument. Measurements at these higher resolutions can be achieved with a fibre optic cable helically wrapped on a cylinder. The effect of the probe construction,...
The distributions of alkaline phosphatase, acid phosphatase,
non-specific esterases, and glycogen were described for the antennal
glands of the freshwater crayfish, Pacifastacus, and the marine crabs
Cancer and Pugettia.
Alkaline phosphatase is confined primarily to the luminal edge
of the labyrinth in all of the above forms whereas acid phosphatase...
Passive sampling is a popular technology for environmental monitoring, and silicone is an ideal choice for a variety of passive sampling applications. The silicone work described here encompasses laboratory and field studies that demonstrate the use of this polymer in novel environments, for new applications, and for emerging compounds. Unique...
Passive sampling devices (PSDs) were used to measure air vapor and water dissolved phase concentrations of polycyclic aromatic hydrocarbons (PAHs) and oxygenated PAHs (OPAHs) at two different environmentally contaminated sites. Environmental contaminates like PAHs and OPAHs are present in both the atmospheric and aqueous environmental compartments. It is known that...
Marine algae have been recognized as a rich resource of new
and unusual organic molecules with diverse biological properties.
The current need to develop new antifungal, anticancer, antibiotic
and antiviral drugs has led to an intense research effort into the
discovery, isolation and structure determination of potential
medicinal agents from...
