Stem mapping of all trees greater than 15 cm dbh has
been completed on the 10.24 hectare watershed (No. 10) at H. J.
Andrews intensive study site. Using a 25 m grid system, mapping
of vegetation into 7 plant communities and then into 4 habitat
types has also been completed....
Previous reports indicate the presence of multiple CYP1A sequences in rainbow
trout, but their functional differences are unknown. This report describes the cloning and partial characterization of four trout CYP1A cDNAs, which are given the tentative
designations CYP1A1v2, v3, v4, and v5. Comparison among these four and three
previously reported...
Species declines and extinctions have been recorded across taxa as evidence of an ongoing global biodiversity crisis. Amphibians are at the forefront of these declines with nearly one third of amphibian species estimated to be at risk of extinction. While many factors contribute to population declines and extinctions, the role...
Heat transfer characteristics and associated temperature and flow fields for natural convection in two-dimensional, square, partitioned and non-partitioned enclosures have been determined for Grashof numbers ranging from 10³ to 10⁶. The vertical side walls of the enclosure are isothermal with all other surfaces assumed to be adiabatic. An adiabatic partition...
The fouling characteristics of cooling tower water
containing various corrosion inhibitors and other additives
on heat transfer surface have been investigated. Corrosion
inhibitors investigated included zinc-chromate and
phosphates. In addition, additives including polyacrylate
and phosphonate (HEDP and AMP) were used to determine their
effectiveness as antifoulants.
The tests were conducted...
Plastic packaging is a cost-effective solution for housing RF and microwave integrated circuits in low cost communication devices. While enabling low cost packaging of integrated circuits, plastic packages including the circuit ground patch (paddle) inside the package can have a significant parasitic effect on circuit performance. The purpose of this...
Variability in wood properties causes boards within a stack of lumber to
dry at different rates and reach different moisture content levels after drying is
completed. The consequence is that the boards will have properties that differ from
ones that were intended to be achieved by the drying process.
The...
