  • Entamoeba histolytica: trophozoite, precyst and cyst studied by atomic force microscopy

    Amoebiasis is a disease caused by the cosmopolite parasitic protozoa E. histolytica; it has been estimated that the 10% of the world population is infected by this protozoa, which represents approximately 50 million of invasive amoebiasis cases and as much as 100,000 deaths per year. E. histolytica have four stages: the trophozoite, precyst, cyst and metacyst; trophozoite is the invasive…

  • Third generation biofuels from microalgae

    Biofuel production from renewable sources is widely considered to be one of the most sustainable alternatives to petroleum sourced fuels and a viable means for environmental and economic sustainability. Microalgae are currently being promoted as an ideal third generation biofuel feedstock because of their rapid growth rate, CO2 fixation ability and high production capacity of lipids; they also do not…

  • Power converters for wind turbines: Current and future development

    The wind turbine generator system requires a power conditioning circuit called power converter that is capable of adjusting the generator frequency and voltage to the grid. Several types of converter topologies have been developed in the last decades; each of them has some advantages and disadvantages. Mainly two converter topologies are currently used in the commercial wind turbine generator systems.…

  • Piezonuclear reactions and DST-reactions

    Over the past two decades a great deal of evidence has been gathered about the existence and the possible energetic exploitation of a new type of reactions predicted by the Deformed Special Relativity, which is an extension of Special Relativity. According to that theory, the energy of every physical phenomenon determines, by deforming it, the space-time in which the same…

  • Molten salt reactors

    Molten salt reactors (MSRs) is an area of growing interest in sectors both private and public. Many advocates of MSRs talk of their potential to deliver safer nuclear power, bringing to the world energy sustainability without the generation of CO2 emissions and at a market-competitive price. Molten salt reactors are characterized by the use of fluoride salts as coolant, in…
