Opis:
The paper presents a new adequate look on the character of motion of any material body, such as moving vehicle. It has been proved, that motion of material bodies has a quantum character. Due to this their consecutive energetic states are obtained by a jump. The phenomenon of quantum in the reference to vehicle kinetics has been derived by indicating its place on the background of characteristics of whole mechanics. The length of vehicle way in particular phases of its motion is that source characteristics the derivatives of which form the development of motion description of a material solid/body. It has been indicated that the quantum nature of body motion does not depend on its magnitude. Thus, as has been noticed, there is an analogy between the macro-body motion and electron motion which change its energy also by jump, by getting from one orbit (energetic level) to another.

Opis:
This work is a continuation of the problems of kinetics, dynamics, and energy of solid on the example of a tool fixed flexibly under cutting. The work consists with three parts. Part 1 covered the kinetics of the system. Present work is devoted to the dynamics of a tool in the machining space-time. Dynamic characteristics of the whole machining system are considered by determining forces being the measures of particular reasons for material cutting. The reasons are the following forces: gravity, inertia, and repel. In the last Part 3 of the work, a special attention is to be paid to the work description and the energy notion.

Opis:
This work investigates kinetics, dynamics and energy of solid on the example of a tool fixed flexibly under the process of cutting. The original approach to the tool kinetics was considered by the Authors earlier. This work consists with three parts referred to the kinetics, dynamics, and energy of solid. Present work is concerned on the development of kinetics problems of a solid represented by a tool fixed flexibly and is a continuation of the problem. Part 1 covers the definition and characteristics of the machining space-time and is referred generally to the kinetics. Then the kinetic and dynamic magnitudes characterizing tool in the space-time are described. The set of these magnitudes has been extended by introducing the properly understood impulse and time-effect. Part 2 of the work is to consider the dynamics of tool in the machining space-time. In Part 3, types of works in the machining space-time and energy of the tool fixed flexibly will be considered; the focus is to be put on an essential difference between work and energy.

repulsive potential of gravity
Opis:
Operationally complete representation of work done and the corresponding to it potential energy within the usual radial/center-bound, nonrotating gravitational force fields comprises two extra terms: linear nonradial and angular nonradial, in addition to the usual radial term. Since these nonradial terms have negative signs, they suggest presence of potentials corresponding to repulsive forces generated by the very same, usual radial attractive force field. The extra linear nonradial term depends on exposure of an orbiting satellite to the distribution of mass within the field, whereas the extra angular nonradial term also depends on that as well as on exposure of the satellite to density of matter of the mass source that generates the usual, locally dominant radial/center-bound attractive gravitational force field.

Opis:
This work is a continuation of the problems of kinetics and dynamics of solid on the example of a tool fixed flexibly under cutting. Present work is concerned on the development of work and energy. A special attention has been paid to the work description by underlying a distinctness and lack of connection with the energy notion. Polarization of these two magnitudes has been revealed. An adequate and extended definition of energy in general, with mechanical energy in particular, is formulated. There are three kinds of mechanical energy considered, located on the stable static potential field being one of the limits of the machining space-time. They are the following energies: repel, inertial, and gravitational. Proper measures/potentials have been assigned to these energies, treating the energy as a mental notion, having no physical meaning in contrast to the potential as the physical magnitude.

In this paper, we study the behaviour of compact relativistic objects with charged anisotropic matter distribution considering Tolman VII type potential for the gravitational potential Z(x) and a particular form of the metric function y(x) proposed for Komathiraj and Maharaj (2007). The Einstein-Maxwell field equations are integrated analytical and we obtain the radial pressure, energy density, charge density, anisotropy and the mass function. A physical analysis of electromagnetic field indicates that is regular at the origin and well behaved. The new stellar model satisfies all physical properties in a realistic star.

Opis:
The work contains some of the elements of adequate quantum theory of impact phenomenon. These elements form the prelude to verification of the existent non-adequate theory of the impact phenomenon. At first a correct definition of impact has been formulated. For comparison, the interpretation of the elastic impact according to the existent knowledge is given. Then, taking advantage of the new correctly formulated the principle of mechanical energy conservation, the energetic states of impacting body have been described. Basing on this, the formula on dynamic deflection has been derived. This formula is adequate in character and fully corresponds with investigated reality.

In this paper, we study the behaviour of compact relativistic objects with charged anisotropic matter distribution considering modified Tolman IV type potential for the gravitational potential Z(x) which depends on an adjustable parameter α and a particular form of the metric function y(x) used by Malaver (2009). The Einstein-Maxwell fields equations are integrated analytical and we obtain the radial pressure, energy density, charge density, anisotropy and the mass function. A physical analysis of electromagnetic field indicates that is regular at the origin and well behaved. The new stellar models satisfies all physical properties in a realistic star for any value of the adjustable parameter.

Opis:
Natural resources are limited, whether as a non-renewable or renewable. Planet Earth has a natural capacity and it is given for the human community. The current pace of development of the world economy and the accelerated population growth are threatened and may soon lead to exhaustion of non-renewable energy resources and exceed the speed of regeneration of renewable resources (water, energy, food), thus leading into questioning the survival of human communities and future generations. Only through the application of the principles of sustainable development (sustainable use of resources) and implementation of logic survival one can assure safe and steady growth to be followed by present and future needs of human being.

Opis:
Geospatial technology has been done to identify spatially the extents of highly suitable and moderately suitable areas for groundwater demarcation. Several input parameters (land use, soil type, slope, geology, geomorphology, and lineament) used to maps Groundwater potential assessment. Each thematic map has been reclassified into five classes. Suitable weightages have been given to each class with respect to its groundwater potential influences. Area of all raster formats of all parameters were calculated by GIS environment. All the weighted input parameters have been overlaid using “Weighted Overlay Analysis” tool in ArcGIS 10.3 platform. The results showed that 8.26 Km2, 441.74 Km2, 812.86 Km2, 198.01 Km2 and 80.57 Km2 of the study area fall in “Highly suitable, High, suitable, Medium suitable, Low suitable and Very Low suitable” category of groundwater potential respectively.

The solutions of the Schrӧdinger equation with Manning-Rosen plus a class of Yukawa potential (MRCYP) have been presented using the Pekeris-like approximation and parametric Nikiforov-Uvarov (NU) method. The bound state energy eigenvalues and the corresponding un-normalized eigen functions are obtained in terms of Jacobi polynomials. Also, inversely quadratic Yukawa, Yukawa, Manning-Rosen and coulomb potentials have been recovered from the mixed potential and their Eigen values obtained. The Numerical results are computed for some values of n at l = 0 with α = 0.01, 0.1, 2 and 5 using python 3.6 programming, and these results could be applied to molecules moving under the influence of MRYP potential as negative energy eigenvalues obtained indicate a bound state system.
