The isolation and sepn. of the mol. variants of monoclonal IgA from cell culture supernatants is possible using several filtration and ion-exchange chromatog. steps, followed by size-exclusion chromatog. for the actual sepn. of the mol. variants. The latte ...
Despite striking advances in functional brain imaging, the cellular and molecular mechanisms that underlie the signals detected by these techniques are still largely unknown. The basic physiological principle of functional imaging is represented by the tig ...
Experimental plasma-edge gradients in JET during the edge-localized-mode (ELM) free H-mode are examined for evidence of the presence and location of the transport barrier region inside the magnetic separatrix. High spatial resolution data in electron densi ...
Members of the newly discovered glycoprotein-associated amino acid transporter family (gpaAT-family) share a similar primary structure with >40% identity, a predicted 12-transmembrane segment topology and the requirement for association with a glycoprot ...
Synthetic boron-doped diamond (BDD) thin film electrodes were tested for the electrogeneration of silver(II). In nitric acid, the kinetics of the silver(I)/silver(II) couple were studied by cyclic voltammetry. The results demonstrate that silver(II) can be ...
Diffusion of Li and Na ions in TiO2, anatase, has been studied using theor. (quantum chem. ab initio periodic Hartree-Fock and a modified semiempirical INDO) as well as electrochem. (chronocoulometry) methods. On the basis of the theor. calcns., the geomet ...
Batch cultures of a mouse/mouse hybridoma cell line secreting a dimeric IgA were performed in combination with a membrane process for the continuous removal of ammonia from the culture medium. The latter involves hydrophobic porous membranes with an assocd ...
Considering the spectral problem of microinstabilities in a curved system, methods for solving the global gyrokinetic equation are presented for the simple case of a cylindrical plasma. They prove to be efficient for computing the full unstable spectrum of ...
Chemical diffusion (D) and surface exchange (k) coefficients for SrFeO3-delta were measured using an electrochemical cell combined with electrochemical impedance spectroscopy (EIS) and potential step technique (PS) in the temperature range of 850-915°C. A ...
Global gyrokinetic particle simulations have been used to search tokamak configurations which are stable again st the ion-temperature-gradient - driven (ITG) modes commonly held responsible for the core anomalous ion heat transport. The stable configuratio ...
