Simultaneous Determinations of Cr(VI) and Cr(III) by Ion-Exclusion/Cation-Exchange Chromatography with an Unmodified Silica-Gel Column
Cr(VI) Cr(III) Ion-Exclusion/Cation-Exchange Chromatography an Unmodified Silica-Gel Column
2010/9/19
In order to characterize the ion-exclusion and cation-exchange properties of an unmodified silica-gel column, the retention behaviors of Cr(VI) and Cr(III) ions were investigated using a Develosil 30-...
Sequential Injection-Cation Exchange Micro-column System for Hemoglobin Typing to Differentiate HbE Carriers
Sequential Injection-Cation Exchange Micro-column System Hemoglobin Typing HbE Carriers
2010/9/19
A weak cation exchange micro-column was incorporated into a sequential injection (SI) system to perform automatic hemoglobin (Hb) typing as an alternative way to measure HbE. Separation of HbF, HbA an...
The martingale approach for credit-risky exchange option pricing
Exchange option Girsanov’s theorem
2010/9/10
An exchange option allows its holder to exchange one asset for another at maturity. In this short paper, the martingale approach, which is based on Continuous martingale representation theorem and Gir...

"Processes controlling the exchange of ammonia between grassland and the atmosphere (GRAMINAE) – results from the Braunschweig field experiment".
Dynamics of ammonia exchange with cut grassland: synthesis of results and conclusions of the GRAMINAE Integrated Experiment
ammonia exchange cut grassland the GRAMINAE Integrated Experiment
2010/1/21
Improved data on biosphere-atmosphere exchange are fundamental to understanding the production and fate of ammonia (NH3) in the atmosphere. The GRAMINAE Integrated Experiment combined novel measuremen...
Emergence of heterogeneity and political organization in information exchange networks
information exchange networks heterogeneity political organization
2010/4/8
We present a simple model of the emergence of the division of labor and the development of a system of resource subsidy from an agent-based model of directed resource production with variable degrees ...
Forward pion-nucleon charge exchange reaction and Regge constraints
pion-nucleon interaction Regge model
2009/11/24
We present our recent study of pion-nucleon charge exchange amplitudes above 2 GeV. We analyze the forward pion-nucleon charge exchange reaction data in a Regge model and compare the resulting amplitu...
Recent results of two-boson-exchange effects in the parity-violating elastic electron-proton scattering
two-boson-exchange parity-violation elastic electron-proton scattering strange quark form factor
2009/11/24
The results of two-boson-exchange effects in the parity-violating elastic electron-proton scattering are reported based on a simple hadronic model. The corrections are calculated including the nucleon...
Resonance properties from a coupled channel meson exchange model
pion-nucleon scattering meson exchange model analytic structure of the scattering amplitude
2009/11/24
In this talk, I present the results on the pole structure of pion-nucleon scattering in an analytic model based on meson exchange. The analytic properties of scattering amplitudes provide important in...
Two-photon exchange to proton electromagnetic properties in time-like region
two-photon exchange nucleon delta form factor
2009/11/24
The contributions of two-photon exchange in the process e++e－ →p+p including N and Δ intermediate states are estimated in a simple hadronic model. The corrections to the unpolarized cross section as w...
Impulse exchange at the surface of the ocean and the fractal dimension of drifter trajectories
Impulse exchange surface of the ocean fractal dimension drifter trajectories
2009/11/12
An impulse-based model is developed to represent a coupling between turbulent flow in the atmosphere and turbulent flow in the ocean. In particular, it is argued that the atmosphere flowing horizontal...
Biosphere-atmosphere exchange of CO2 in relation to climate:a cross-biome analysis across multiple time scales
Biosphere-atmosphere exchange CO2 cross-biome analysis multiple time scales
2010/1/21
The net ecosystem exchange of CO2 (NEE) varies at time scales from seconds to years and longer via the response of its components, gross ecosystem productivity (GEP) and ecosystem respiration (RE), to...
A two-dimensional horizontal hydrodynamical model has been used to estimate
the changes that a harbour road will cause in the water exchange of an
estuary. The research area has been the Kokemaenjok...
Modelling Water Exchange and Transit Times in Till Basins Using Oxygen-18
Water Exchange Transit Times Till Basins Oxygen-18
2009/10/27
The application of hydrological models to data on conservative tracers can
yield information about transit times and storage volumes and may provide an
independent test of the model structure.In thi...
