Abstract:We study the composite odd numbers via their indices with a function ranging through all of them. This mapping allows us to demonstrate that the set of these indices are described with two families of finite sequences with arithmetic differences. Composite odd numbers are then shown to be obtained as differences of two squa [...] Read more.

Abstract:The micrometer-sized network structure of a calcium-alginate hydrogel, which was synthesized from sodium alginate, calcium sulfate dihydrate, trisodium phosphate 12-hydrate, glycerol, and water, was observed using an optical microscope, cryogenic-scanning electron microscope, and an energy-dispersive X-ray spectrometer. For [...] Read more.

Abstract:Sandpile Paradigm was proposed by Bak, Tang and Wiesenfeld (Bak et al. 1987) to explain simple model of Self-Organized Criticality (SOC). When the piles fall on the sandpile (input driver), we will see, that at some critical point (reaching adequate angle of response), sand will slide down to get the saturation phase.

Abstract:SMEs and their growth are critical to the prosperity of economies around the world and our research tried to determine the factors which explain the growth of these firms. Our research questions are the following: How is it possible to develop more middle-size firms in the Québec MM-IT sector? And how can the competitiven [...] Read more.

Abstract:Science is a matter of asking for information by specifying the difference between fact and opinion. Fact in a scientific context is a generally accepted reality, but still open to scientific inquiry, as opposed to an absolute truth, which is not a part of science. The hypotheses and theories are generally based on objectiv [...] Read more.

Abstract:Silver modified polyacrylonitrile-activated carbon (Ag-PAN-AC) composite fibers containing various AC concentrations were prepared by using an electrospinning process. Ag-PAN nanoparticles were initially prepared via in-situ reduction of silver nitrate using hydrazinium hydroxide as a reducing agent. The influence of AC con [...] Read more.

Abstract:Low density polyethylene (LDPE) containing activated carbon (AC) was foamed with azodicarbonamide (ADC) through an extrusion process. The effects of ADC and AC contents on the cellular structure, void fraction, density, thermal and mechanical properties, and crystallinity of composite foams were investigated. The density of [...] Read more.

Abstract:Cerium conversion coatings (CeCC) have been synthesized for corrosion protection of AA2024-T3 aircraft alloy through application of potentiostatic regime in aqueous solutions of diammonium pentanitrocerate - (NH4)2Ce(NO3)5. This cerium compound is used for first time for this purpose. The impact of the following deposition [...] Read more.

Abstract:The Davenport diagram, which illustrates the interactions of pH, bicarbonate and pCO2 as related to respiratory/metabolic phases of acidosis/alkalosis was transformed into a computerized neural network. This transformation enables computer-assisted prediction of acidosis/alkalosis subtypes on the basis of any two factors f [...] Read more.

Abstract:The processing of fibre reinforced carbon nanotube (CNT) loaded polymer composites (nanocomposites) requires that CNTs be mixed (or loaded) into the polymer prior to impregnating the fibres to fabricate a nanocomposite. The fabrication process uses vacuum-assisted resin transfer moulding (VARTM), which is complicated due to [...] Read more.
