Francisella tularensis is a gram-negative facultative intracellular
coccobacillus that primarily infects macrophages. The causative agent of tularemia,
this bacterium is considered among the most infectious organisms known, requiring
fewer than ten organisms to cause disease. Although ubiquitous in nature,
transmission to humans is rare but can occur via insect bites,...
Observations of temperature and pressure in the upper 100 m were taken with a towed thermistor chain in January 1980 north of Hawaii. The observations were taken as a part of a cooperative investigation of the North Pacific subtropical front entitled FRONTS-80. The chain was towed on four occasions over...
Observations of temperature and pressure between 10 and 70 m depth
were taken with a towed thermistor chain during late August and early September, 1978, about 400 km northwest of Scotland as a part of the JASIN Experiment. The chain was usually towed at a speed of 3 mis around...
Observations of temperature between 20 and 40 m depth were made with a towed thermistor chain in the North Pacific (50N, 145 W) during the Mixed Layer Experiment (MILE). The chain was usually towed at a speed of 3 m/s around a 20km square on alternate days for a three-week...
Vertical cross-sections of temperature in the Sargasso Sea and across
the Gulf Stream and a warm core ring were obtained with a towed thermistor
chain in September 1981. The thermistors were distributed in the upper
70 to 120 m during three runs. Salinity was also measured at two locations
on...
Northeastern Oregon geology and climate provides moderately productive conditions for forest management and timber production. Although site preparation and planting are commonly used silvicultural practices, little research exists on the efficacy of specific forest herbicides and responses of seedling survival and growth in this region. This research seeks to improve...
Here we report results from an extensive survey of
dissolved organic carbon (DOC) in the Arctic Ocean, which
was achieved by means of a high-resolution, in situ UV fluorometer
deployed on a nuclear submarine. Based on a strong
linear correlation observed between fluorescence (320 nm excitation,
420 nm emission) and...

This report is a critique of a study by the U.S. Environmental Protection Agency that found a statistically significant correlation between the application of the herbicide 2,4,5-T (dioxin) and miscarriages in the Alsea watershed. "If there is a relationship between herbicide use and miscarriages in the 'Alsea Basin' and its...
