A New Look at Kinetics in Relation to Food Storage

Modern mathematical software and user-friendly interactive programs can simplify and speed up kinetics calculations. They also open the way for new approaches to storage data gathering and analysis. This is demonstrated with a recently introduced simple exponential model that is interchangeable with the Arrhenius equation and endpoints and successive points methods and that estimates chemical degradation kinetics parameters from a small number of isothermal or nonisothermal experimental data. Also presented are a method to determine shelf life using two chemical markers and a global phenomenological model for peaked reactions, such as those encountered in lipid oxidation. Also recently introduced are freely downloadable Wolfram Demonstrations and other interactive software to generate, visualize, examine, and/or compare actual or hypothetical storage scenarios in minutes. They include programs that solve pairs of simultaneous nonlinear algebraic or differential rate equations by passing two reconstructed ...

    Astrophysical Sources of High-Energy Neutrinos in the IceCube Era

    High-energy neutrino astrophysics has come of age with IceCube's discovery of neutrinos in the TeV to PeV energy range, attributable to extragalactic sources at cosmological distances. At such energies, astrophysical neutrinos must originate in cosmic-ray interactions, providing information ... mehr

    Reactor Neutrino Experiments: Present and Future

    Reactor neutrinos have been an important tool for both discovery and precision measurement in the history of neutrino studies. Since the first generation of reactor neutrino experiments in the 1950s, the detector technology has advanced greatly. New ideas, new knowledge, and modern software ... mehr

    Electroweak Measurements at the LHC

    To our present knowledge, all of the physics at the LHC can be described in the framework of the Standard Model of particle physics. Indeed, the newly discovered Higgs boson with a mass close to 125 GeV seems to confirm the predictions of the theory. Thus, in addition to looking for direct ... mehr
