    Opis:
    The paper presents the results of studies of geomorphological processes in the surroundings of tourist paths with an effect on vegetation and soil conditions in the subalpine and alpine zones of the Tatra Mts. Hiking paths at the local level represent a significant factor for increasing efficiency of sheet wash and concentrated runoff and subsequent intensive deep erosion. They can interrupt continuous surface runoff and operate as the local base of erosion base for a part of the slope over them, with gravitational effect of surface runoff from rainfall and melting snow water, which increases the effect of slope denudation. The base of erosion of the paths increases the potential of gravitational failures and decreases the soil-debris cover stability. In these conditions, the development of slope movements accelerated evidently. Morphologically, hiking path can influence the accumulation of snow layers and creates the conditions for persistent snowfields. Blocking effect of the paths is also reflected in a slowdown and the subsequent accumulation of snow mass by snow creep, snow sliding and snow mass gliding. Hiking paths may be a part of areas with development of aeolian-deflational processes and associated destructions of the soil-debris cover.

    Opis:
    Edible mushrooms have been appreciated globally for their organoleptic, nutritional and chemical properties. In the present study, fruiting body of Calocybe gambosa, wild growing in Serbia, has been chemically characterized (content of macronutrients, soluble sugars, tocopherols, fatty and organic acids) and its bioactive (antimicrobial and antioxidant) properties were evaluated. The results obtained suggest that this mushroom is a source of carbohydrates and proteins (72 g/100 g dry weight (dw) and 16 g/100 g dw, respectively), with a low fat content (1.5 g/100 g dw). Sugar analysis revealed the presence of trehalose (3.82 g/100 g dw) and mannitol (0.22 g/100 g dw). Tocopherol composition revealed the presence of α-tocopherol (7.8 μg/100 g dw), while fatty acid analysis revealed the presence of 24 fatty acids with the prevalence of polyunsaturated fatty acids. Amongst organic acids, oxalic, quinic, malic, citric and fumaric acid were detected (2.8 g/100 g dw, 1.45 g/100 g dw, 11.3 g/100 g dw, 1.3 g/100 g dw, 0.08 g/100 g dw, respectively). Comprehensive antioxidant activity analysis (reducing power, DPPH radical scavenging activity, β-carotene/linoleate and TBARS assays) indicate that the mushroom is a perspective antioxidant source, whereas its antimicrobial potential turned out to be moderate. Nevertheless, at a sub-inhibitory level, the methanolic extract disrupted cell-to-cell communication using Pseudomonas aeruginosa PAO1 as a model system. Finally, enrichment of oatmeal cookies with C. gambosa flakes not only improved their nutritional value, but was praised among the participants in sensory evaluation test, indicating that along with results of chemical composition and biological activity, this mushroom has a potential to be regarded as functional food.

    Opis:
    We have used an all-optical photoluminescence-imaging technique to measure excitonic transport in three types of GaAs structures in which the excitonic transitions vary from allowed direct-gap excitons to forbidden, doubly-indirect Type-II excitons. We f nd remarkable differences in the transport properties of these excitons. Our studies show that bulk free-exciton transport exhibits an anomalous laser power-dependent diffusivity, whereas quasi-2D interfacial excitons and Type-II cross-interface excitons do not. Additionally, we observe localization of cross-interface excitons at the potential disorder induced by the heterointerface roughness.
