Opis:: Badanie wilgotności gleby może być wykonywane za pomocą metody bliskiej podczerwieni. W pracy został przedstawiony wpływ układu zasilania na wyniki pomiaru. Do badań wykorzystano piasek gliniasty lekki w pięciu przedziałach wilgotności. Wyznaczono optymalny zakres napięcia zasilania (od 3,4 do 3,8 V) dla badanego przedziału wilgotności (od 0,48 do 20 %).
In soil moisture measurement we use a ooptoelectronic system of psychrometry. In study was checked influence of the powersupply on results of soil moisture measurement. The soil in study was used in five compartments with different soil moisture. The optimum range of tension of current was appointed (3,4 - 3,8 V), in studied compartments of soil moisture (0,48 - 20%).

Opis:: Objectives. The aim of this study was to discover the relationship between the performance of different mechanical movements of rowers, and define its effect on the motor programs of the cyclic movement in athletes living in rural and urban areas. Materials and method. Twenty-two male rowers participated in the experiment using a rowing ergometer (Concept2, USA). The experiment consisted of 3 tests examining the maximal power of the pull-ups (MPbpu). The movement mechanogram was registered with a specialized complex Noraxon’s 3D MyoMotion (Noraxon Inc., USA). The software of the complex allowed calculation of the values of the joint angles from the accelerometer data. The Origin Lab 8.5 program was used for the mathematical and statistical processing of the signals from the mechanograms. Results. It was found that all experiment participants had a stepped controlled increase in the power of single bar pull-ups leading to a corresponding proportional increase in the frequency of rowing – test 1 and, conversely, a stepped controlled increase in the rowing frequency accompanied by a proportional increase in the power of the bar pull-ups – test 2. The involuntary dependence of the power and the rate was due to the peculiarities of the central cyclic movement programming, according to which the forces and durations of the active and passive bar pull-ups phases were interconnected and regulated together. The voluntary power-rate dependence control led to the breakdown of these links in the motor program of cyclic movements and to the separate control of these parameters. Conclusions. Motor programs in cyclic movement may be created in the same pattern in tope level sport and recreation, as well in different environmental conditions – gym halls (movement simulators), professional and recreational water sport tracks.
