     This research study the effect of Photovoltaic surface temperature on Photovoltaic panel output characteristics. First,circuit simulator PSPICE was used to compose Photovoltaic panel model at 75 W, 4.8 A and 21 V. Then, study the behavior of it under varying conditions (solar insolation, environmental temperature and PV panel surface temperature). ABM feature of PSPICE was used to include the above rameters in PV PSPICE model and produced temperature dependent voltage.

In order to develop a effected method to reveal the presence of  explosive, numerous detection techniques have been studied that are capable of detecting explosives, The current study provides an overview of the present  techniques like LIBS which is an atomic spectroscopy, and examined  a new technique for detecting called laser induced fluorescence (LIF). LIF essentially measures the optical emission of the excited energetic materials by laser.

Several studies have been conducted to measure different type of gamma ray buildup factor for its importance in measuring the dose resulting from Electromagnetic rays use and its shielding In this study gamma ray buildup factor for two shielding materials water (Z_eff =7.42) and graphite (Z=6) within the energy range 4-10 MeV and up to 5 thickness mean free path has been studied.
