Industrial diamond Industrial diamond
Part of the 1999 Industrial Minerals Review. A review of the state of the global industrial diamond industry in 1999 is presented. World consumption of industrial diamond has increased annually in recent years, with an estimated 500 million carats valued between $650 million and $800 million consumed in 1999. In 1999, the U.S. was the world's largest market for industrial diamond and was...

Atlantic Flyway review: Piedmont-Coastal Plain, Region IV, Fall 1999: Patuxent powerline right-of-way (390-0764) Atlantic Flyway review: Piedmont-Coastal Plain, Region IV, Fall 1999: Patuxent powerline right-of-way (390-0764)
Fall 1999 was among the poorest seasons in this banding station's 20 years of operation. Record high capture totals were set for only two species: Ruby-throated Hummingbird (41 individuals captured, none banded; previous high 21) and White-breasted Nuthatch (two individuals banded; previous high, one). The only other species that stood out as being unusually numerous was Blackpoll...

Atlantic Flyway review: Piedmont-Coastal Plain, Region IV, Fall 1999 Atlantic Flyway review: Piedmont-Coastal Plain, Region IV, Fall 1999
In a slight reorganization, the Mount Nebo station in the mountains of western Maryland near Oakland was moved to Region III (Western Ridge), in exchange for Lakeshore Estates in Leon County, Florida, which we welcome to Region IV. This was the year of the hurricane in Region IV, with the majority of stations commenting on summer drought, persistent easterly winds, or hurricanes. Nine of...

Effects of the mosquito larvicide GB-1111 on mallard and bobwhite embryos Effects of the mosquito larvicide GB-1111 on mallard and bobwhite embryos
Golden Bear Oil or GB-1111 is a petroleum distillate that is used throughout the United States as a larvicide for mosquito pupae. The oil forms a barrier at the air-water interface, which suffocates air-breathing insects. There are few published studies on non-target effects of GB-1111 but the product label warns that ?GB-1111 is toxic to fish and other aquatic organisms.? Fertile eggs...

Habitat management for wintering American Woodcock in the southeastern United States Habitat management for wintering American Woodcock in the southeastern United States
Although much information has been gathered on American woodcock (Scolopax minor) wintering east of the Lower Mississippi Alluvial Valley, that information has not been compiled into a single source assembled for land managers. The objectives of this paper are to pose a few important questions that should be addressed before implementing a land management plan and to briefly review some...

Hydraulic characteristics of a rectangular mixed-cell rearing unit Hydraulic characteristics of a rectangular mixed-cell rearing unit
We describe a fish rearing unit modification that establishes mixed flow reactor (MFR) behavior in a rectangular vessel so as to eliminate metabolite concentration gradients, increase current velocities and improve solids scour at low water exchange rates. A standard raceway section 14.5 m long was modified to create six counter-rotating mixed cells, each 2.4 m wide by 2.4 m long. Cells...
