The life history and wing pattern variation of the intertidal
shore bug, Saldula palustris (Douglas), were studied in field and
experimental populations from June 1970 until February 1972.
The study site was an estuarine salt marsh on Yaquina Bay
near Toledo, Oregon. The insects live below mean high water level...
NADPH-cytochrome P-450 reductase, an important enzyme in the
cytochrome P-450-dependent microsomal monooxygenase system, was
purified from insecticide-resistant (R) and -susceptible (S) house
flies (Musca domestica, L.) and from the black blow fly (Phormia
regina, Weigen). Proteolytic degradation to a P-450 - inactive form
of the reductase was reduced during the...
The purpose of this study was to document the life
history of the xylophagous elmid beetle, Lara avara. and to
estimate its contribution to wood degradation in Oregon
streams. Field collections, mark-recapture, and laboratory
rearing were used to determine details of the life cycle.
Laboratory feeding studies and field population...
A total of 399 crossbred ewes from two birth years were raised
under two management systems, irrigated vs. dryland hill pastures.
The crossbred ewes were sired by North Country Cheviot, Dorset, Finnsheep
and Romney rams that were mated to Suffolk and Columbia-type
ewes. Hampshire rams were the terminal sire breed...
This paper analyzes macroeconomic variables to determine their effect on the United States’ trade balance. Data on GDP, exchange rates, money supply and the trade balance are adjusted for inflations to get inflation-adjusted variables. This will lead to a regression with the goal of determining which factors explain the variability...
Chalkbrood is a mycosis of larvae of the alfalfa leafcutting bee,
Megachile rotundata (Fabricius). It is a serious threat to alfalfa seed
growers in western North America who use populations of this bee for
pollination. Basic studies were conducted to determine the etiology of
this disease and the course of...
High concentration and low efficiency have plagued the Chinese banking industry since the establishment of the national banking system in China. Recently, foreign banks have been allowed to enter the Chinese market, and small and medium-sized commercial banks have expanded their market share. At the same time, Chinese bank efficiency...
This study examines the relation between political parties in the United States and foreign direct investment (FDI) using a panel data gravity model of 42 countries from 1980 to 2006. The Democratic Party and the Republican Party differ on economic platforms, and the changing of relative power in government between...
