    Abstract: Advance of pest diversity on urban area is reality of modern time. Actual biological technologies are unable to prevent this process. Sometimes struggle leads to negative results in particular under use of chemical pesticides. Use of clean ecological methods must be strategy of nearest future. The basis of such a technology must be imitation of wil... Show More

    Abstract: Here it is started with the proportionality between Planck’s and related gravitational parameters. Using the ratio between Planck mass and related minimal gravitational radius (half of Planck length) we obtain maximal radial density (kg/m) in gravitational field. On the other hand, minimal radial density one obtains using the ratio between Planck m... Show More

    Abstract: In this article we obtain the Coulombian potential of spinor and scalar particle with the quantum field theory, there is no difference between the spinor and scalar particle. Similarly the Newtonian potential of spinor particle and scalar particle are also obtained with the quantum field theory, however it is found that the Newtonian potential of s... Show More
