Recently, we demonstrated that a radio-frequency-free electromagnetostatic (RF-free EMS) cell could be retrofitted into a triple quad mass spectrometer to allow electron-capture dissociation (ECD) without the aid of cooling gas or phase-specific electron injection into the cell [1-2]. Subsequently, we used our RF-free EMS cell in the same instrument platform...

Potatoes require adequate nitrogen to produce quality tubers and high yields. Organic farming practices are designed to build soil nutrient levels
gradually. In organic systems, nitrogen (N) enters the soil in the form of crop residue and amendments (e.g., manures, composts, and specialty products).
Much of the N added to...
The total kinetic energy release and fission mass distributions for the fast neutron (En = 3–100 MeV) induced fission of 232Th, 233U, 235U, 237Np, 239Pu, 240Pu, and 242Pu have been measured using the LANSCE facility. The neutron energies were deduced from time-of- flight measurements. The fission fragments were detected using...
The goal of this study was to better understand stream communities through a perspective that might make their structure, organization, and development more understandable. This goal was approached
through the following objectives:
1. To determine the assemblages of stream organisms and define subsystems within a stream community.
2. To explain...
The intracellular mutualism between cnidarians and photosynthetic dinoflagellates (genus Symbiodinium) is responsible for the physical and trophic structure of diverse coral reef ecosystems. This relationship, based on nutrient exchange, allows for high productivity in tropical waters, which are generally nutrient-poor environments. Numerous environmental stressors currently threaten the health of corals,...
Genome instability is a prerequisite for the development of cancer. It occurs when genome maintenance systems fail to safeguard the genome’s integrity, whether as a consequence of inherited defects or induced via exposure to environmental agents (chemicals, biological agents and radiation). Thus, genome instability can be defined as an enhanced...
People turn to mass spectrometry to answer some of life’s most important questions. From carbon dating of archeological finds to newborn blood screening tests, mass spectrometry allows us to measure molecules which helps advance our knowledge of life and the world we live in. One area of mass spectrometry that...
Kernel hardness (KHA) is a major factor determining break flour yield (BFY) and end-use quality of common wheat (Triticum aestivum L.). Within the soft wheat class, genotypes with consistently softer grains than common soft wheat are considered to be 'extra-soft'. In addition, 'extra-soft' wheats have greater BFY than common soft...
Economic methodology is revisited to address issues in
fishery management, and survival analysis is suggested as an
analytical tool to solve the uncertainty problem in
evolutionary economics. Survival analysis can clarify in
statistical terms the impacts of fishery regulation and
economic and biological changes on the fisherman's final
decisions of...
