  text: ' The current carrying capacity, which is determined by the electrical-thermal
    behaviour, is one of the main features of an electrical contact system. The purpose
    of this study is to develop an analytical model which describes the electricalthermal
    behaviour of electrical contact systems. Established mechanical, electrical, thermal
    and contact physical relations are combined to design the analytical model. Differential
    equations with appropriate boundary conditions are used to solve the heating problem.
    The various parts of an electrical connector represent separate subsystems. The
    geometry, the material properties and the heat transfer coefficients for the contact
    system, the terminal clamp and the wire have been taken into account. These different
    subsystems have been connected to obtain the overall temperature distribution.
    In order to verify the analytical model, contact systems made of three copper
    alloys with different electrical and thermal properties are investigated experimentally
    at various current loads. It was shown that the analytical model can predict the
    temperature rise for simple geometry well. Using the analytical model several
    parameters can be easily changed. Moreover, the main influencing factors and their
    relationships can be identified directly on the equations. Therefore, the physical
    mathematical point of view of an analytical calculation can help Research Article
    British Journal of Applied Science & Technology, 4(1): 18-39, 2014 19 to understand
    the model structure of a contact system.'

  text: We report on investigations of platinum clusters with about five to 400 atoms
    that are deposited from a cluster beam on to crystalline graphite surfaces. Scanning
    tunneling spectroscopy in an UHV environment at liquid helium temperatures reveals
    the existence of distinct peaks in the conductivity of the cluster-on-surface
    system. For negative voltages, the peak separations scale with the inverse particle
    height, which hints at a quantum size effect in these metallic “quantum dots”.
