    Lightning is a natural phenomenon that generates a high electric field during thunderstorm. It has been
    reported that lightning strikes amid storms can occur around 100 times per second. The atmospheric
    electric field is an imperative parameter during a thunderstorm. Therefore, monitoring the electric field
    and its parameters is the best way for local lightning forecast. The electric field monitoring data can
    validate the accuracy of weather prediction in a local area from meteorology department or by using
    equipment specially designed to measure this electric field that exists when the phenomenon of lightning occurs. In this paper, the relationship between lightning, air humidity and temperature is discussed to understand the post lightning effect on these electric parameters. Additionally, the characteristics of the parameters are observed and analysed.

    The use of electroosmotic is fast becoming a proven technique for manipulating particles in microfluidic
    systems. Several approaches were experimented to improve the force and thus the moving particles in
    the fluid. This paper will study the effect of microelectrode on the moving particles in latex using a
    particle image velocimetry and to test the velocity of particles movement at various frequencies from
    10kHz to 500kHz. The result shows the behaviour of latex particles at different frequencies varying
    from low frequencies up to high frequencies under AC electrokinetic forces such as dielectrophoresis
    (DEP) and AC electroosmosis (ACEO).
