    Opis:
    An evaluation of existing insulation and remediation technologies for solid mineral waste storages is carried out. Results of field observations at one of the largest tailings in Russia are given. A quality of atmospheric air, and surface and ground water are estimated in the impact areas of a magnetic separation waste storage at an iron ore deposit of the Kursk Magnetic Anomaly. An effective method of landfill’s surface insulation using polymeric materials is offered. The technological insulation process by means of a self-propelled screening machine is described. The suggested method will allow preserving an artificial deposit until the time of its rational mining, stopping water and wind erosion from its surface. Environmental conditions in its location area will be improved and pollution of atmosphere, soil, and natural water will be reduced.

    Opis:
    The paper provides an assessment of the potential technogenic impact of sulphide-containing wastes produced by ore extraction and processing at the Ozernoe deposit, which is currently at the initial stage of mining. The analysed averaged samples of ore and wastes of mining and processing were obtained in the course of semi-industrial experimental preproduction. The results of monitoring studies in the area of sulphide-containing dumps formed at an exploring mine in the 1960s were used for assessing a potential hazard of the wastes. The origin of acid mine drainage is described. Advantages and shortcomings of tests assessing acid mine drainage are considered. The used express-method of acid indication allows to reliably determine the risk of acid mine drainage by the values of acidic and neutralising potentials formed by rocks. An estimation of acid mine drainage formation and heavy metal migration is carried out at dumps of the exploring mine. The forecast of environmental impact is given for the future wastes of mining and processing at the Ozernoe deposit.

    Opis:
    Introduction and objectives. Chlamydia (C.) felis can cause infection which may be associated with conjunctivitis and/or respiratory tract disease, particularly in kittens, but could also be the cause of the disease in adult cats. Infection is more common in multi-cat environments. The zoonotic potential of C. felis appears low, but exposure to this microorganism is possible by handling the affected cats, by contact with their aerosol, and also via fomites. Materials and method. In the study, 140 cats of various breeds from Košice region in Slovakia were studied. Conjunctival samples were obtained from 71 clinically healthy cats (50.7%) and 69 cats with clinical signs of conjunctivitis and upper respiratory tract impairment (49.3%). Cats were divided into 4 groups according to breed and type of environment in which they lived. In the 1st group were cats kept inside only (n=33), in the 2nd group, free-roaming cats (n=50), the 3rd group comprised stray cats, taken from the streets (n=28), and the 4th group included cats kept in shelters or deposit devices (n=29). Molecular method PCR and DNA sequencing was used as the diagnostic method. Results. Overall positivity was 17.1%. Of the 24 positive cats, the highest positivity was detected in the population of stray cats (35.7%) and shelter cats (31%). In the group of free-roaming cats, 10% had positivity. No positive animals were detected in the group of cats kept inside only. It was also found that the risk of C. felis in cats with clinical signs of disease was more than 7-fold higher than in cats without clinical signs of conjunctivitis and respiratory tract. Conclusion. The obtained results show that cats, especially stray and shelter cats, can be important sources of feline chlamydiosis, and due to their close contact with people they can present a risk for transmission.

    Opis:
    Colonization by marine organisms such as foraminifers, molluscs, bryozoans, brachiopods and red algae during the Middle Miocene (Early Badenian) transgression near Přemyslovice (Carpathian Foredeep) was initially affected by a cool water current of unclear origin. However, shortly afterwards, fallout of volcanic material caused a total termination of the biota. After this catastrophe, the biota started recolonize the area. The succeeding association, adopted to warm-water input, is characteristic of the climatic optimum during the Early Badenian and is comparable with those of other sections referred to this interval in the Carpathian Foredeep (such as Kralice nad Oslavou, Podbřežice, and Hluchov).
