Opis:: The conducted research aimed at establishing the pace and range of the formation of spruce windfall in Compartment 93 of the Babia Góra National Park, where in 2005 by the decision of the Park’s Director, with the approval of the Scientific Council of the Park, a monitoring area was created. During field work the range of the existing windfall area was mapped through determining its outermost points and their stabilization by means of the GPS. During the research an analysis of the aerial photographs made available by the Babia Góra National Park was carried out, in order to determine the changes in the range of the area deprived of trees. The analyzed photographs covered the area of 5 ha in Compartment 93 of the Park. The evaluation of changes in the tree layer was based on the graticule reproducing the 10 x 10 m area of the real land. The “lack of trees” was stated when the areas were exposed in at least 75%. The comparative analysis of the images from aerial photographs of Compartment 93 in 2003, 2011, 2012 and 2014 showed distinct changes in the range and size of the gaps made by fallen trees. The share of the gaps in the forest stand in the whole analyzed area increased from 2% in 2003 to over 52% in 2014. Therefore, the progression of the size of the changes is considerable and the disintegration of the tree layer is growing, especially comparing the 2003–2011 and the twice shorter 2011–2014 periods. In the analyzed periods, the increase in the gap area was similar (ca. 26%), yet the pace of the phenomenon was twice faster. The obtained results were an argument in favor of increasing the monitoring area from 0.28 ha to 1.55 ha.

Opis:: Lead, as a heavy metal, is harmful to living organisms (both plants and animals) and it is relatively mobile in the environment. In this article we present the results of the monitoring of the lead content in local allotment gardens (Zielona Góra, Poland). We examined both the total and the phytoavailable form. Soil samples were collected in eight places in the allotment gardens, and two places in the neighbourhood of the allotment gardens. The lead content in the soil met the Polish soil ground standards (Regulation by the Minister of the Environment of 9.09.2002). The total content of lead varied from 21 to 39 mg kg⁻¹, (12–14 mg kg⁻¹ at reference point) and the form potentially available for plants from 10 to 19 mg kg⁻¹ (6–7 mg kg⁻¹ at reference point). The content of lead does not exceed the threshold values according to Polish law.
Ołów, jako metal ciężki, jest szkodliwy dla organizmów żywych (zarówno roślin jak i zwierząt) I jest względnie ruchliwy w środowisku. W pracy przedstawiono wyniki badań monitoringowych dot. zawartości ołowiu ogólnego oraz przyswajalnego w glebach ogródków działkowych Zielonej Góry. Próbki glebowe pobrano z 8 miejsc w obrębie ogrodów oraz z 2 miejsc referencyjnych zlokalizowanych w sąsiedztwie ogrodów. Zawartość ołowiu w glebach nie przekraczała wartości progowych wyznaczonych wg prawa polskiego, przyjętego w zarządzeniu Ministra Środowiska z dnia 9 września 2002 r. Zawartość ołowiu całkowitego wahała się od 21 do 39 mg kg⁻¹, (12–14 mg kg⁻¹ w punkcie referencyjnym) a ołowiu w formie potencjalnie dostępnej dla roślin od 10 do 19 mg kg⁻¹ (6–7 mg kg⁻¹ w punkcie referencyjnym).

Opis:: Purpose: The current study aimed to quantify the main influences and the interactions (joint effects) of gender, leg and type of target on the biomechanics of front kick quality. Through the quantification, we tried to identify the relevant factors related to the kick accuracy and maximum velocity for coaching practice. Methods: A ten-camera NIR VICON MX40 motion capture system (250 Hz) was used to determine the kicking foot maximum velocity from two well-trained subject groups (8 males and 6 females). Each subject performed both left and right front kicks in a lateral standing position into the air (without a physical target), to a board, to a table tennis ball and to a training shield. The target were set on a height corresponding to a height of solar plexus of each participant. Results: The results showed that all the three factors (gender, leg and type of target) have significant influences on kicking speed ( p < 0.001) and significant interaction (joint effect) was only found between gender and target ( p < 0.001). Further analysis revealed that the males’ kicking maximum velocity was affected more by board, while females’ one was affected by the size of the target. Conclusions: The results would seem to suggest that, for males, kick-to-a-board may be the more effective method for increasing kick quality, compared to other type of target. For females, kick-to-a-small-ball appears to be effective method for increasing kick maximum velocity.

Opis:: The test results presented concern ordinary concretes containing 5 coarse crushed aggregates made from igneous rocks and one made from gravel. The two aggregates i.e. granite and basalt were from southwest Poland and three i.e. granite, basalt, granodiorite were from West Ukraine. Natural gravel was comparatively tested as well. The tests of aggregates dealt with bulk density, grinding ratio, content of irregular grains and content of mineral powder. Flexural and compressive strength of concretes were tested after 28 and 365 days. Better strength properties of concretes containing Polish aggregates in relation to comparable petrographic Ukrainian aggregates were found.
