Nitrosomonas europaea is a chemolithoautotrophic bacterium that oxidizes ammonia (NH₃) to obtain energy for growth on carbon dioxide (CO₂) and can also produce nitrous oxide (N₂O), a greenhouse gas. We interrogated the growth, physiological, and transcriptome responses of N. europaea to conditions of replete (>5.2 mM) and limited inorganic carbon...

Over the past century, the tuna canning industry has been dominated by a few big companies, some of
them having changed of ownership or merged: these oligopolistic firms are the “big three” in the USA,
Van Camp, Star Kist, and Bumble Bee, the French Saupiquet, the Italian Trinity Alimentari and...
Electrochemical sensing provides a quantitative alternative to colorimetric reactions within paper-based devices. The paper-based devices were fabricated by screen printing the conductive and reference inks onto porous substrates that were evaluated using cyclic voltammetry. Devices were evaluated based on the magnitude of the average anodic peak height, which correlates with...

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,...
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...
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...
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 biosystematic investigation was undertaken in 15
species and three subspecies of the genus Aster, in western
North America. Previous studies had been based entirely on
external morphological features, and it was believed that
much could be learned about the natural affinities of the
taxa by exploring their cytological and...
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...
