    Notes: TlInGaAs/InP double heterostructures (DHs) were grown on (100) InP substrates by gas-source molecular-beam epitaxy. Almost no occurrence of Tl interdiffusion at the InP/TlInGaAs heterointerface was confirmed. The photoluminescence (PL) intensity for the DH was approximately ten times stronger than that of the single heterostructure. The PL peak energy and its variation with temperature for the TlInGaAs/InP DH decreased with increasing Tl composition. For the DH with a Tl composition of 13%, the PL peak energy varied only slightly with temperature (0.03 meV/K). This value corresponds to a wavelength variation of 0.04 nm/K and is much smaller than that of the lasing wavelength of InGaAsP/InP distributed feedback laser diodes (0.1 nm/K). © 2000 American Institute of Physics.

    Notes: SiGe microcavities with Ge dots were fabricated by employing strain-balanced SiGe/Si Bragg reflectors, and it was observed that photoluminescence from Ge dots embedded in the microcavity structure was significantly modulated due to the cavity effect. The characteristic luminescence of the microcavity was observed up to 200 K, and the thermal activation energy of the luminescence was largely improved compared with that of cavities with quantum wells. © 2002 American Institute of Physics.

    Notes: [Auszug] THE actual clotting phase in blood coagulation JL is initiated by two parallel sets of reactions catalysed by thrombin. Fibrinogen is converted to fibrin through the scission of fibrinopeptide from the parent molecule1 and the more recently recognized plasma globulin, fibrin stabilizing factor ...

    Notes: Abstract: The jam phenomenon in traffic flow wastes not only considerable traffic-transportation time but also great amounts of fuel due to many accelerate-decelerate actions. From traffic-economic and traffic-pollution viewpoints, the suppression of traffic jam is an important issue we have to solve. The present paper shows that -norm, which has been used in the field of control theory, can reveal the traffic jam phenomenon in an optimal velocity traffic model under an open boundary condition. Furthermore, we suppress the traffic jam in the model by the decentralized delayed-feedback control method. Some numerical simulations are shown to verify our theoretical results.

    Notes: Summary The solubilities of azobenzene derivatives in water have been determined at 5 °C intervals from 0° to 40 °C to obtain the information both about the effect of polar groups on the solubility of aromatic compounds in water and about the action of polar groups to the iceberg-formation in the vicinity of hydrophobic part of the solute in water environment. From the results the imaginary super cooled pure liquid has been taken as a standard state and the thermodynamic parameters of solution of azobenzene derivatives in water have been calculated.

    Description / Table of Contents: Zusammenfassung Zwei optisch aktive organische Säuren wurden aus D- und L-Alanin synthetisiert und ihr Bindungsverhalten an Rinder-Serum-Albumin geprüft. In der Untersuchung fanden wir, daß die D-Form der Verbindungen, die an das Albumin gebunden werden, sich stärker anlagern als die L-Form innerhalb eines pH-Bereichs von 5,0 bis 8,0. Im pH-Gebiet 4,0 jedoch konnten wir keinen Unterschied zwischen dem Verhalten der beiden optischen Isomeren feststellen. Die spektralen Untersuchungen lassen schließen, daß die D-Form fester mit dem Albumin verbunden ist als die L-Form.
    Notes: Summary Two optically active organic acids were synthesized from D- and L-alanine and we studied their binding behaviors with bovine serum albumin. In the investigation we found that the D-form of the compounds bound with the albumin more than did the L-form within the range of pH 5.0 to pH 8.0 At pH 4.0, however, we did detect no difference in the binding between the optical isomers. The spectral study led to a conclusion that D-form bound with albumin more tightly than L-form did.

    Notes: Summary The solubility of azobenzene in water and aqueous alcohol solutions was determined at 5 °C intervals from 0° to 40 °C. Prom the results the thermodynamic parameters for the transfer of one mole of azobenzene from water to aqueous alcohol solution were calculated. It was found that the process was endothermic: furthermore, it was invariably accompanied by a positive unitary entropy change. The solubilizing mechanism of alcohols was explained in terms of an adduct-formation with the compound to be dissolved by means of hydrophobic interaction.

    Notes: Summary The solubilities of the following compounds in an aqueous sodium dodecyl sulfate solution were determined at 25°, 30°, 35° and 40°C: biphenyl, azobenzene, p-chloroazobenzene, p-aminoazobenzene, p-N,N-dimethylaminoazobenzene and p-nitroazobenzene. From the results the thermodynamic parameters for the transfer of the model compounds from water to SDS micellar environment were calculated. The resulting thermodynamic parameters were not so certain, but suggested that with biphenyl, azobenzene and p-chloroazobenzene which seem to be solubilized in the SDS micellar interior the solubilizing process is a result of a favourable increase in entropy, and that with p-aminoazobenzene, p-N, N-dimethylaminoazobenzene and p-nitroazobenzene which seem to be solubilized in the SDS micellar surface the solubilizing process is a result of a favourable decrease in enthalpy. The favourable increase in entropy was explained in terms of iceberg and the favourable decrease in enthalpy in terms of interfacial energy.
