Opis:
W artykule prezentuje się dwa sposoby rozwiązania modelu grawitacji dla dwóch układów terytorialnych: dla byłego województwa łódzkiego i teoretycznej strefy wpływu Łodzi. Przeprowadza się weryfikację statystyczną wyników oraz porównuje rozwiązania modelowe ze stanem rzeczywistym.
Spatial links between Łódź and its raw material sources were analyzed on the example of raw material supplies to meat processing plants. For her analysis the author employed the gravitation model solving it in two ways. The first one consisted in reducing the gravitation formula to the regression model, and the other one in accepting a priori the index of the power and estimating coefficient G by applying the potential model. Estimations were thus made for two territorial systems of the former administrative province of Łódź and the theoretical zone of Łódź influence estimated on the basis of Converse’s formula and premises provided by an empirical analysis. Deviations between theoretical and real ties allowed to determine areas' of surpluses, equilibrium, and shortages in supplies. Comparative analysis of both employed ways of solving the accepted function revealed that the second way of model solution yields better results from the point of view of optimization of the food-provision zone of Łódź. The functions of such zone in the light of the performed analysis are carried out best by. the second spatial system, according to the second way of the model solution.

Opis:
The paper has outlined a broad perspective of references for the (particular and general) theory of relativity to various domains of human knowledge and to technique. These references are presented both in their current and historical dimension. The following issues are discussed: 1) the place of the theory of relativity in the development of physics and cosmology, 2) its contribution to the development of mathematics, 3) the significance of the theory of relativity in the development of technique, and 4) the role of the theory of relativity in the development of philosophy. The theory of relativity is – aside to quantum mechanics – one of the two basic paradigms (relativistic paradigm) of contemporary physics. Likewise it plays a fundamental role in further development of physics, astronomy and cosmology, contributing at the same time to the development of mathematics and philosophy. The author indicates that it is groundless to refer to the theory of relativity in the efforts to relativise and subjectivise cognitive and axiological questions. The theory of relativity does not relativise all its concepts of magnitudes, but it even confers the absolute status on certain magnitudes, which have been deemed relative before.

Opis:
In the paper a special role of gravitation as an interaction causing formation of large astrophysical objects with small entropy is analyzed. This is apparently in contradiction with the II law of thermodynamics. Some basic types of such objects have been examined from the point of view of entropy dynamics. It has been stressed that in the far future black holes will play a special role in creation of conditions for maintaining the existence and the development of civilization. It has been shown numerically that in the universe with accelerating expansion the conditions for a surviving civilization will be worse than in standard cosmological models because of faster thermal death.

Opis:
The results of the experiments on water migration in unsaturated granular media performed with dynamic neutron radiography technique are presented. It was found that the porosity of the medium did not determine the kinetics of the process in a marked way. The influence of gravity was found to be considerable for media like coarse sand and gravel, consisting of large grains. No effect of gravitation on the water migration in clay beds was observed. The results are discussed in terms of the classical Washburn-Bosanquet theory of adhesion driven motion of the liquid in a straight circular capillary under gravity. It was found that this theory provides only qualitative description of the water migration within granular media, and the viscous dissipation effects are greatly underestimated.

Opis:
This paper presents results of the verification of a heat exchanger composed of gravitation thermal pipes installed in a broiler chicken feeding facility. The objective of the study was to verify the possibility of the application of a power management system including a heat recovery system in a heavy-duty environment of a broiler chicken fattening facility and to specify effects of the system upon the specific consumption of energy for space heating and ventilation of the animal house. The calculation of the thermal balance of the animal house documents that the power management system that includes a heat recovery exchanger unit may reduce the thermal capacity of external sources of heat in the animal house by 26.5% even when subject to extreme conditions and at the atmospheric temperature of -12°C and the age of chickens being 1 day. The results of the metering and calculations of the efficiency have proven that the heat exchanger reaches the operational efficiency of 10–47% and thermal efficiency of 20–80% even during the most demanding operational first twenty days of the breeding cycle of broiler chickens. The specific consumption of energy for space heating and ventilation related to 1 kg of the live weight of chicken in the animal house facility A provided with a heat recovery exchanger unit at the average atmospheric temperature during the cycle being 4.3°C amounted to 278.5 Wh. In the animal house B as not provided with the heat recovery exchanger units hosting the same number of chickens and provided with the same process and thermal loss due heat transmission through peripheral structures being one half compared to the animal house A, the specific consumption of energy per 1 kg of the live weight of chicken was 420.5 Wh.

Opis:
The paper covers a critical approach to the natural reality study which is the method of scientific cognition. The existent so called d`Alembert's rule is the link of reality on which the specific attention is focused. The critics is directed to the fictional inertia force covered in the mentioned rule. The necessity for its elimination from the reality description has been presented. Instead, it is proved that a real inertia force occurs. A proper exemplification material has been delivered with two examples of force equilibrium of the system. One of them refers to a rigid system being both under stable and unstable states. The second one covers also these two states but it is referred to a mass-flexible system. Finally, the discussed solution of the problem has been explained on the example of mathematic pendulum and a mass-string system.

Opis:
In the paper, the outline of a new quantum theory of gravitation is presented. The energetic states of a material body, stable and unstable, are described. Characteristics of a body motion in a gravitation-inertia space-time has been given. It has been proved that all the time both gravitation and inertia are co-existent, independent on the position of a moving object. This is the reason of that twolink name of the space-time. A thorough in-depth analysis of the problem made it possible to state that so called the law of common gravity is a hyperbolic approximation of a proper course of inertia force. Therefore the mentioned courses have only two common points. One of them, the initial point belongs also to the course line of the gravity force, constant on the whole length of space-time. This theory is adequate in character and thus generally does not corresponds with the existent classical theory of gravitation.

In this paper, a theory of the phenomenon of planetary circulation around the Sun is presented, as well as the stability of solar systems is explained. This theory describes the circulation of planets and Rother mass-holding bodies around the Sun as a phenomenon consisting in the principle of differentia pressure in solar systems and thus excludes gravitation phenomenon as the phenomenon of attraction.
