    Abstract : NMDA-receptor dependent membrane potential oscillations and postinhibitory rebound are examples of intrinsic membrane properties of many neurons of rhythm-generating networks, and are considered to play major roles in the operation of the spinal locomotor network of the lamprey vertebrate model. A significant feature of many lamprey spinal cord neurons is their ability to generate pacemaker-like membrane potential oscillations in the presence of the glutamate agonist NMDA. READ MORE

  2. 2. The chemistry of flotation activation and depression of iron-containing sulphide minerals

    Author : Xianghuai Wang; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mineralteknik; Mineral Processing;

    Abstract : Thermodynamic calculations, electrochemical techniques, flotation and adsorption tests were used to study the physico-chemical principles involved in the flotation, activation and depression of the common ironcontaining sulphide minerals. Thermodynamic calculations on iron-xanthate-sulphur-water systems indicate that insoluble ferric hydroxo- xanthates can be obtained at a very low xanthate concentration in the neutral to weakly alkaline pH range, in which no liquid dixanthogen is formed.
