Abstract The Oribatida (known as moss mites or beetle mites) increase the breakdown of organic material in the soil. The paper analyses the dynamics of their abundance and number of species after various treatments enriching the soil in 4 study areas: afforested post-agricultural area in the Tuchola Forest, afforested degraded post-military training area in Bydgoszcz-Jachcice, and forest nurseries at Białe Błota and Bielawy. The results show that in post-agricultural and degraded soils at the initial stages of forest succession, the density and number of species of oribatid mites were low, even after phyto-land-improvement (afforestation and lupin as green manure). In the forest nurseries, however, we recorded a positive effect of soil revitalizing after mulching with forest ectohumus (i.e. organic surface layer of the soil). The inoculation of soils with forest mesofauna appeared more effective in nursery plantations of silver birch (Betula pendula) and small-leaved lime (Tilia cordata), as compared with Scots pine (Pinus sylvestris). Thus to revitalize degraded soils effectively and to accelerate forest succession, apart from phytoland- improvement, it is advisable also to reintroduce mesofauna, e.g. with the use of forest ectohumus.

The paper deals with the occurrence, development and harmfulness of Deporaus betulae (L.). The majority of field studies was carried out at Training Forest Enterprise (TFE) Masaryk Forest in Křtiny (District Brno-venkov) in 2010 and 2011. In addition to this, the species was studied in detail also in a laboratory. It occurred mostly on Betula pendula and Carpinus betulus. Rarely, the species was found on Alnus glutinosa and Corylus avellana and only sporadically on Fagus sylvatica, Quercus petraea, Tilia cordata and T. platyphyllos. In the studied area, larvae and pupae hibernate. Beetles occur on trees from the end of April to the beginning of July, sporadically later. Females lay on average 2.5 (in the laboratory 4.4) eggs into rolls on B. pendula, on C. betulus 2.2 eggs. During two months, they damage on average 5.3 cm2 leaves creating 14 rolls and laying 35 eggs into the rolls. Larvae consume only 1.7 cm2 leaf blade. The development of the species takes three to four months from egg laying to the departure of larvae into soil. On leaves of B. pendula of an average area of 14.2 cm2, females roll up the same area (about 11.2 cm2) as on leaves of C. betulus of an area of 21.7 cm2. Into the rolls, they lay on average the same number of eggs. The average number of eggs in rolls increases with the increased area of B. pendula leaf blade. Trees partly compensate for the reduction of assimilatory area also by the growth of the area of neighbouring undamaged leaves (on average by 12.7 %).

Maintenance is a complex, extensive and important issue in terms of its impact on the quality of manufactured products or services provided in all areas of industry. The importance of predictive maintenance for the industry in the 21st century is crucial. However, the right approach to maintenance management is often underestimated in many companies today, although it can have a very positive effect on the company’s efficiency. Using the example of a practical application, the paper includes a comparison of three main maintenance concepts – classical (reactive), planned, predictive through the simulation software Witness. Maintenance concepts are compared in terms of their ability to solve and eliminate failures that occur in production facilities during operation.

Objective. To study the efficiency of inoculation of seeds by biological preparations under in-fluence on humus balance in growing crops in short crop rotation. Methods. Field, laboratory, cal-culation-comparative. Results. It was found that the highest entrance of organic matter in the soil was due to the use of organo-mineral fertilizing system NPK-manure-green manure, which contrib-utes to the increase of organic carbon reserves by 17.4 t/ha without the use of microbial prepara-tions and by 18.0 t/ha against the background of microbial preparations in comparison with the mineral fertilizing system. The use of microbial preparations under the fertilizing systems NP-manure-green manure allows to increase the amount of organic matter entering the soil by 1.2 and 1.6 t/ha during crop rotation. Under the use of organic fertilizers (manure, green manure) in com-bination with mineral ones and seed inoculation, not only the recovery of fertility of sod-podzolic soil, but also increase in the content of humus within the limits of 0.43–0.53 t/ha is reported. The use of manure on the background of the NPK makes it possible to increase the humus reserves in the soil by 0.11 and 0.15 t/ha per year. During crop rotation, the amount of newly formed humus in this variant exceeded its mineralization loss by 0.42 t/ha without microbial preparations and by 0.58 t/ha on the background of microbial preparations. Conclusion. The positive effect of the use of biological preparations under inoculation of seeds in combination with the organo-mineral fertiliz-ing system on the content of humus in sod-podzolic soil on average by crop rotation was estab-lished. Organic-mineral fertilizing system (NPK + manure + green manure) provides the highest growth of humus reserve in soil — 0.53 t/ha per year. The use of microbial preparations in the cul-tivation of crops under this fertilizing system contributes to the increase of humus content in the soil by 0.16 t/ha during crop rotation.

Background: Military training plays an important protective role in enhancing mental health. However, the effects of military training on psychological resilience and depression among college freshmen in China remain unclear. The present study aimed to evaluate changes in psychological resilience and depression through military training among college freshmen, and to investigate associated psychosocial factors including childhood trauma that may influence its effects on psychological resilience.Methods: A prospective and self-comparison study design was employed. College freshmen who received 3 weeks of military training were recruited. Socio-demographic variables were collected and childhood trauma exposure was estimated by the Childhood Trauma Questionnaire (CTQ). The Connor-Davidson Resilience Scale (CD-RISC) and Patient Health Questionnaire (PHQ-9) were used to assess psychological resilience and depression before and after the military-style training.Results: The military training significantly increased the total and subscale scores of CD-RISC (p < 0.001), and decreased the PHQ-9 score (p < 0.001). The proportion of students with clinical depression reduced from 10.5% at baseline to 7.2% after the training (p < 0.001). Improvement of CD-RISC scores was positively affected by male gender and urban area, while negatively affected by older age, and higher baseline scores of PHQ-9 and CTQ. A significant correlation was found between changes in scores of CD-RISC and PHQ-9 through the training (r = −0.238, p < 0.001).Conclusions: Military training may have a positive effect on increasing psychological resilience and reducing depressive symptoms among college freshmen, especially in male students and those from an urban area, while older age, childhood trauma, higher depression levels, and resilience at baseline may weaken, or even mask its positive effect. Follow-up research should be considered for the long-term effects of military-style training.

Student Square was opened on September 1, 2007 at the intersection of the busy Moscow Avenue and K. Ivanov Street. The total area is 2,5 hectares. The predominant tree species are Tilia cordata Mill., Betula pendula Roth and Acer platanoides L. In 2016, the first inventory of the square flora was carried out, 94 plant species from 79 genera and 37 families were identified. Pinopsida are represented by 4 cultivated introducents. Only 6 species from the Poaceae are monocotyledons. The systematic diversity of the flora is very low. Virtually every genus is represented by only one species. The average level of species wealth in one family is 2,54. The number of families with one species is 21 (56,8%). The top ten in the number of species families are concentrated by 63,8% of the species. The spectrum of the leading families of the flora of the Student Square indicates its thermophilic appearance. The share of synanthropic species in the flora as a whole is 53,2%. The index of synanthropization ( Is ) of the square flora is 1,14 and emphasizes the anthropogenic nature of the landscape. The aboriginal fraction of the flora is strongly altered ( Is = 0,48). In the ecologo-cenotic spectrum, there is a preponderance towards plants of open habitat types, among which weed species predominate (34%), among which 4 are malignant invasive species: Acer negundo L., Conyza canadensis (L.) Cronq., Lepidotheca suaveolens (Pursh) Nutt., Xanthoxalis stricta (L.) Small. On the second place is a group of meadow plants (16%). The distribution of other coenotic groups in general is consistent with the regional spectrum of the flora of Chuvashia. The hygromorph spectrum is dominated by mesophytes (71,3%), followed by xeromesophytes (16%), the share of the remaining groups varies from 1,1 to 6,4%. The trofomorph spectrum is dominated by mesotrofs (62,8%) and megatrofs (36,2%). Aliens fraction is 30,9% of the square flora. 17 species (58,6%) are cultivated introducents, and the rest - weed plants. Kenophytes (75,9%) predominate, ergasiophytes and ergasiofigophytes (24,1% each), epekophytes and agrio-epekophytes (65,5%), North American (31%) and Iranian-Turanian (20,7%) species.
