Iron is absolutely necessary for the maintenance, the defense, the differentiation and
last, but by no means least, the growth and cellular division of almost all living
organisms including Nitrosomonas europaea, an ammonia oxidizing bacterium. Given
the necessity of iron, it is not surprising that N. europaea evolved several irondependent...

The genus Ormyrus has a worldwide distribution and
comprises about sixty recognized species. The higher
taxonomic relationships of the genus are uncertain, as
evidenced by its placement in the families Ormyridae,
Pteromalidae, or Torymidae. Here, the genus is described
in detail and a preliminary catalog of the world species
is...
A techno-economic analysis (TEA) was performed to evaluate the technology, cost, and resource use for algal biofuel production based on today’s economics and technology. The basic goal of this study is to develop a model to calculate the mass and energy balances and costs to produce 10 million gal of...
Chemical dosimetry developed in response to needs created by
developments in the field of high-energy radiation. Shortly after the
discovery of X-rays in 1895 and of radioactivity in 1896, the deleterious
effects of ionizing radiation were recognized. To guard against the
injurious effects of radiation in medical application, dose-measuring
methods...
The purpose of this study was to investigate the effects of
logging on the productivity, structure and biomass of a periphyton
community developed in mountain streams. The three streams used
in this investigation were located in the coast range of Lincoln
County, Oregon. They were selected for similarity of habitat,...
