  • Neutron and gamma-ray shielding properties of modified Ni- Ti- X Mo
           maraging steels

    • Abstract: MCNP5 program was used to investigate the neutron and gamma shielding properties of Ni-Ti- X Mo maraging steels. The MCNP5 program experimental setup was designed using neutrons of 14.1 MeV from sealed neutron tube and 60Co as a gamma ray source. Particular attention was given to the shielding properties of neutron and gamma for low nickel free cobalt, titanium containing modified maraging s...

  • Two methods for extracting the parameters of a non-ideal diode

    • Abstract: We describe two methods of extracting physical parameters of a non ideal p-n diodes. These include the ideality factor, saturation current and series resistance. The proposed techniques that treat extraction parameters, using the current-voltage characteristic (I,V) forward biased. The first method is to learn three different points of the curve, with the coordinates of these points, one can...

  • Surface and thermodynamic studies of micellization of surfactants in
           binary mixtures of 1,2-ethanediol and 1,2,3-propanetriol with water

    • Abstract: Surface physico-chemical and thermodynamic studies of some aqueous surfactant solutions were carried out by employing conductance, surface tension and dye solubilization (UV-Vis absorption spectroscopy) techniques. From conductivity and surface tension measurements, critical micelle concentration (CMC), counter-ion association constant (), equivalent conductance at infinite dilution (o), sur...

  • Relativistic causality versus superluminal communication: Is the quantum
           mechanics a semi-empirical theory'

    • Abstract: The work analyzes the compatibility between the classical freedom, the local relativistic causality and the non-local behavior of quantum mechanics in the frame of the stochastic approach of the quantum hydrodynamic analogy (SQHA). The work describes the role of the quantum potential in generating the quantum non-local dynamics in a fluctuating environment. The analysis shows that it is poss...

  • Hydrocarbon trapping mechanism and petrophysical analysis of Afam field,
           offshore Nigeria

    • Abstract: The structural trapping mechanism and petrophysical attributes of Afam field, offshore Niger Delta was evaluated using 3D seismic reflection data and composite well logs data. The structure maps and seismic sections show that the anticlinal structure at the centre of the field, which is tied to the crest of the rollover structure assisted by faults, is the principal structure responsible for...

  • Privacy preserving data publishing: Review

    • Abstract: Privacy preserving data publishing (PPDP) methods a new class of privacy preserving data mining (PPDM) technology, has been developed by the research community working on security and knowledge discovery. It is common to share data between two organizations in many application areas. When data are to be shared between parties, there could be some sensitive patterns which should not be disclo...

  • Development of an approach for mapping of features thermal and hydric of
           watersheds: Case of the watershed of Brezina (Northwest of Algeria)

    • Abstract: The objective of the present study is to present the parameters of the hydrological assessment of a steppe area from the data of remote sensing. Adopted methodology rests on the cartography of the various parameters of the hydrous and energy balance on one year scale. Several methods are used. Thus, for cartography of precipitations, one uses in a combined way the relief, the distance of the...

  • Studies on structural, surface morphology and optical properties of Zinc
           sulphide (ZnS) thin films prepared by chemical bath deposition

    • Abstract: Zinc sulphide (ZnS) thin films have been prepared by chemical bath deposition method. X-ray diffraction (XRD) is used to analyze the structure and crystallite size and scanning electron microscopy is used to study the particle size and morphology of ZnS thin film. Optical studies have been carried out using UV-Visible-NIR absorbance spectrum. The band gap value of the film is calculated and ...

  • Soil carbon storage in dominant species of Mangrove Forest of Sarawak,

    • Abstract: Carbon storage in forest ecosystems involves inordinate components including plant biomass carbon and soil carbon. Sequestration of carbon along with other aggressive conservation efforts helps to reduce the increasing negative impact of global warming on the environment and mangroves as the coastal forest. The objective of this study was to assess the soil carbon storage of dominant plant s...

  • Teaching the effect of variables on the brightness of a light bulb in a
           simple electrical circuit using a pneumatic system model (PSM)

    • Abstract: An experiment-based analogical pneumatic system model (PSM) was developed in this study for the purpose of teaching 5th grade students (11 years old) the variables that have an effect on the brightness of a light bulb in a simple electric circuit. Understanding the analogical relationship between source and target in teaching the variables that have an effect on the brightness of a light bul...
