ABSTRACT Scrippsiella spp. resting cysts, unlike many other dinoflagellate cysts, possess an outer layer of calcite beneath which is a thin sporopollenin wall. This feature may affect cyst survival through [...]

This paper presents a new methodology for incorporating origin and destination (O&D) network effects into the fleet assignment process. The methodology uses a decomposition strategy to combine a modified version [...]

ABSTRACT Large-scale, open, microalgal feed cultures for hatchery and nursery production of marine invertebrates inevitably becomes contaminated with various microbes that can affect productivity and usability of the harvested biomass. [...]

In 2002, Travelocity lost revenue and market share to competition as the business environment changed. Travelocity and Sabre collaborated to develop the enterprise network model (ENM). The ENM combines discrete [...]

Fleet assignment models (FAM) are used by many airlines to assign aircraft to flights in a schedule to maximize profit. Major airlines report that the use of FAM increases annual [...]

The pattern of ionization energies of the lanthanide elements is analyzed. It is believed that knowledge of ionization energies is needed for understanding the chemistry of the elements. The effects of pairing, exchange, and orbital interactions on ionization energies of the lanthanides are also assessed.

The ionization energies of atoms and atomic ions in the s,p,d,and f blocks of the periodic table are reviewed. The irregular behavior of the first and second ionization energies across the transition metal and rare earth periods is explained in terms of electronic configurations of atoms and ions.

Many e-commerce principles were pioneered in the airline industry. These include the first business-to-business electronic information exchange and industrywide electronic marketplace. This environment provided unprecedented opportunity for operations research (OR) [...]
