  • Graded PA6/PA12 blends prepared by selective laser sintering

    • Abstract: In this study the manufacturing of graded PA6/PA12 blends by selective laser sintering (SLS) was investigated. Sintered blend specimens were analyzed by scanning electronic microscopy and flexural tests. The PA6/PA12 parts with functionally-graded composition in the Y and Z directions were built by SLS. Information on the pure component properties and the microstructure and mechanical proper...

  • Determination of dispersivity in the subsurface foreshores of River Mersey
           Outer Estuary

    • Abstract: This paper determines contaminant dispersivity in the coastal sand of River Mersey Outer Estuary using results of field measurement from dye solute injection. Dispersivity is an alternative parameter for describing the characteristic behaviour of porous media. In this case, 3-D plumes in 2-D Photo-images were taken from multiple injection zones across the foreshore. The colour images were ca...

  • Theoretical modeling of strain in the single screw feeder of cassava flash

    • Abstract: The aim of this study is to model screw feeder unit to handle granulated wet cassava to the flash dryer column. The knowledge of the flow behavior, physical and mechanical properties, rheology of the product and the geometrical characteristics of feeders unit were essential to evaluate the best conditions of handling granulated cassava based on the theory of virtual works. The effect of gran...

  • Life cycle assessment of cassava flour production: A case study in
           Southwest Nigeria

    • Abstract: Global climate change resulting from increased greenhouse gas emission and environmental pollution remain a serious threat to the world. Food processing industries is one of the major contributors to global greenhouse gas emissions. Intergovernmental Panel on climate change (IPCC) reported that greenhouse gas emission should be reduced to avert the worst effects of climate change. One of the...

  • Measurement of energy requirements for size reduction of palm kernel and
           groundnut shells for downstream bioenergy generation

    • Abstract: The study estimated the amount of energy required for grinding palm kernel shell and groundnut shell using laboratory hammer mill and also characterize their ground physical properties. The material type and hammer mill screen aperture significantly influenced the energy requirement for grinding the two materials. For a given screen aperture size, groundnut shell consumed more energy than pa...

  • The spraying field characteristics and distribution of deposition of
           droplets of electrostatic oiler

    • Abstract: Electrostatic oiler are made as the research object, the multiple field spray characteristics of air flow field, electric field and discrete fog field in the process of spraying were analyzed. The influence of electrostatic spray deposition characteristics has been studied by changing the electrostatic voltage and electrode gap. The experiment about electrostatic oil spray has been verified....

  • Comparison of acoustic emission parameters for fiber breakage and
           de-lamination failure mechanisms in carbon epoxy composites

    • Abstract: Acoustic emissions (AE) generated by a structure under stressed condition provide a passive method to understand the flaw growth phenomenon. In complex structures, such as composites, characterisation of AE signals generated by various failure mechanisms enhances such understanding. Sample level tests have been carried out on carbon epoxy unidirectional laminate in longitudinal direction of ...

  • Application of Webgis in the development of interactive interface for
           urban management in Batna City

    • Abstract: In the last years, the distribution of spatial and non-spatial data on the internet plays a crucial role in national development. It facilitates communication between administration, decision-makers and citizens for urban management. In order to encourage the sharing and disseminating of data, the present study aims to develop and implement WebGIS framework for urban management, which offer ...

  • Catalytic wet peroxide oxidation of maleic acid: Characterization of
           copper/micelle templated silica-3-aminopropyltrimethoxysilane and kinetics

    • Abstract: The study of catalysts enables the catalyst scientist to identify and understand the important steps such as active sites and stages in a catalysts lifetime. It is thus possible for scientists to design in more rational way, new and efficient catalysts. Therefore, the aim of this study was characterization of copper/micelle templated silica-3-aminopropyltrimethoxysilane (Cu/MTS-AMP) catalyst...

  • Enhancement or suppression of dehumidification process by surface

    • Abstract: In many engineering applications, either the suppression or the enhancement of dehumidification is desired. If so, the dehydration in air-conditioned space can be solved, less condensation water pollution can be achieved, or the dehumidification process can be more efficient. In this study, the effects of various surface treatments were explored to enhance or suppress the condensation. It wa...
