The learning process includes a variety of research methods, varying degrees of complexity and importance, which are required by a person in a variety of spheres of life. The article scientifically substantiates the use of a complex method of plantography in the process of teaching biomedical disciplines to determine the functional parameters of the human foot arch. Application of the plantography method in practical classes of the discipline "Human Physiology" will increase interest in learning, since the determination of individual state parameters of the musculoskeletal system will allow students not only to expand the range of knowledge of the physiological profile, but also to develop their skills of research conduct. In the course of our research, the indicators of the condition of students’ foot arch in different modes of loading were identified. The analysis of the results allowed us to determine the so-called "risk group": a group of students who under the influence of the load demonstrated static forms of deformation of the foot arch, while there is a transition of the foot index from one qualitative evaluation zone to another, from "normal" to the category: "flattened", "slightly flattened" and "flat". Therefore, increasing the load on the foot arch leads to a decrease in its springing capabilities. Thus, the data of individual parameters of the foot index obtained by students during the research work in practical classes can contribute to the correct distribution of students in medical groups for physical education. Keywords: plantography, human foot arch, risk groups, research activities.

Purpose. At the stage of development of modern information systems for controlling the process of breaking up trains on the humps, the main task is to determine such conditions for cuts' rolling, under which the established safety requirements for breaking up, as well as the requirements for the safety of wagons and cargo in them, are fulfilled. The determination of such rolling modes is undoubtedly a rather complex optimization problem, the solution of which is being addressed by a large number of scientists. In this regard, it can be considered that this problem remains relevant, therefore, the purpose of this research work is to determine such modes of braking of cuts of the train, which ensure their reliable separation when rolling from the top of the hill to the sorting tracks. Methodology. To carry out research on the process of dismantling trains on the hump, the method of simulation was used, and to search for the braking modes of the cuts of the calculation group, the Box complex method was used. Findings. The conditions for separating cuts of the calculated group of the train were investigated, and an iterative procedure was developed to optimize the braking modes of all the cuts of the train, which makes it possible to ensure the maximum value of the minimum interval in the calculated group. In this case, the specified procedure takes into account the intervals between the cuts, both on the arrows and on the retarders of the brake positions of the downhill part of the hill. Originality. It has been established in the work that when determining the modes of braking the cuts of the train, it is necessary to take into account the possible separation of the cuts on all elements of the downhill part of the hill - arrows and retarders. The problem of finding the optimal braking modes for all cuts of the train has been formalized and solved, which, in turn, allow providing reliable conditions for separating adjacent cuts at the turnouts and brake positions of the downhill part of the hill.  Practical value. The developed method can be used in the study of the sorting process, as well as in the automation systems for disbanding trains on the hump when determining the braking modes of the cuts.

Abstract The main subject of this paper focuses on scientific and research activities conducted in the Institute of Mining Engineering and Safety of the VŠB-Technical University of Ostrava. Cooperation between the VŠB-Technical University of Ostrava and OKD A.S., the only representative of coal mining in the Ostrava-Karviná coal basin, has recently begun to develop again. This paper describes an example discussed in a certain study, which has been undertaken for the Paskov mine, OKD a.s., dealing specifically with the evolution of microclimate parameters in mines that depend on the progress of mining activity at deeper levels over a period of several years. To this end, a special program, aimed at determination of the necessary refrigerating capacity, was established at the VŠB-Technical University of Ostrava.

Five N-p-phenyl substituted benzamidines were studied by DC and DP polarography in a wide pH range. Coulometric results show that the overall processes are four-electron reductions. Logarithmic analysis of the waves indicate that the process are irreversible. The influence of the pH on the polarographic parameters was also studied. A UV spectrophotometric study was performed in the pH range 2-13. In basic media some variations in the absorption bands were observed due to the dissociation of the amidine group. A determination of the pK values was made by deconvolution of the spectra. Correlations of both the electrochemical parameters and spectrophotometric pK values with the Hammett substituent constants were obtained.

Background and objectives: Limited evidence exists exploring perceptions of which aspects of a pain management program are perceived as valuable and impactful. The aim of this study was to explore patient beliefs about which aspects of a pain management program were valued and/or had perceived impact. Materials and Methods: One-on-one structured interviews were conducted with 11 adults three months after their completion of the Spark Pain Program at Westmead Hospital, Sydney, Australia. Concepts in the transcripts were inductively identified and explored, utilizing thematic analysis to better understand their relevance to the study aim. Results: Four themes emerged: (1) “The program overall was positive, but…”; (2) “I valued my improved knowledge and understanding of pain, but…”; (3) “I valued the stretching/relaxation/pacing/activity monitoring”; and (4) “I valued being part of a supportive and understanding group”. Participants reported that they liked being treated as an individual within the group. A lack of perceived personal relevance of key messages was identified in some participants; it appears that patients in pain programs must determine that changes in knowledge, beliefs, and attitudes are personally relevant in order for the changes to have a significant impact on them. Conclusions: This study provides new insights into aspects of a pain management program that were perceived as valuable and impactful, areas that “missed the mark”, and hypotheses to guide the implementation of service delivery and program redesign.

Exposure of sheep to Borreliaburgdorferi sensulato (s.I.) complex, the causative agent of Lyme borreliosis (LB), has been reported in tick-abundant areas worldwide, while no data have been reported in Greece. The aim of the study was to identify the hematological alterations in sheep with seropositivity against Borrelia burgdorferi (s.I.). Blood samples were obtained from 318 tick infested sheep for blood analysis and serological determination of IgG and IgM antibodies against B. burgdorferi by indirect immunofluorescence antibody (IFA) assay after exclusion of endo-ectoparasites and other tick-borne infections. A total number of 162 sheep met the inclusion criteria, allocated in four groups based on the presence or absence of IgG and/or IgM; sheep found negative for IgM and IgG (Group A), positive for IgM (Group B), positive for both IgM and IgG (Group C) and positive for IgG (Group D). Anemia, thrombocytopenia and normal or decreased leukocyte count, mainly due to lymphopenia were the main hematological features observed in seropositive sheep. The presence of these features raises the suspicion of Borrelia infection in tick infested sheep. The seropositivity of 23.58% in sheep raises concerns of Borrelia circulation, especially in rural areas and potential risk of transmission to humans.

Permucosal osseointegrated dental implants are a highly effective and predictable treatment modality for edentulism. This review discusses some controversial aspects of the definitions for success and failure of root-form dental implants. The discussion will focus on the underlying pathologies that, if untreated, may lead to loss of the implanted device. Few clinical syndromes are described based on human pathological material and clinical presentation. The theoretical chronological relationship between implant loss and the incidence of pathology of the soft- and hard-tissue seal around implants is also discussed. The review also examines the finding that implant failures are not randomly distributed in the treated populations and that implant loss clusters in specific high-risk groups and individuals. Known risk indicators, and possible risk factors, are discussed, taking into account the patient, the reconstruction, the implant, and implant site-specific factors. Particular emphasis is placed on the need for better determination of whether periodontal patients are at higher risk for implant failures as a consequence of their increased susceptibility to infectious, inflammatory-response-driven tissue breakdown.

Incremental Sheet Metal Forming

Development of new technologies and processes for small batch and prototype production of sheet metal components has a very important role in the recent years. The reason is the quick and efficient response to the market demands. For this reasons new manufacturing concepts have to be developed in order to enable a fast and reliable production of complex components and parts without investing in special forming machines. The need for flexible forming processes has been accelerated during the last 15 years, and by these developments the technology reaches new extensions. Incremental sheet metal forming (ISMF) may be regarded as one of the promising developments for these purposes. A comprehensive research work is in progress at the University of Miskolc (Hungary) to study the effect of important process parameters with particular emphasis on the shape and dimensional accuracy of the products and particularly on the formability limitations of the process. In this paper, some results concerning the determination of forming limit diagrams for single point incremental sheet metal forming will be described.

Welding Processes

The heat input during conventional arc welding processes can be readily calculated knowing the power taken from the power source. The efficiency coefficient can be taken from the appropriate literature standards. Here, the intention of the performed research work was to develop a procedure for determination of heat input in arc and laser welding processes implementing Adams equation - modified Rykalin equation for two dimensional heat distributions (2-D). To realize this idea, it is necessary to determine two characteristic temperatures points in the HAZ with known peak temperature, and to determine distance between them. Implementing measured values for distance in Adams’ equation, heat input in arc welding can be directly determined in arc welded joints.In laser beam welding, the absorption of the beam in the metal is not known, so that the welding heat input cannot be calculated directly, and direct implementation of Adam’s equation is not possible i.e. absorption coefficient has to be determined first, and after that calculation of heat input is possible.The peak temperatures corresponding to specific microstructures can be obtained by performing welding simulation, by the Gleeble 1500 simulator in our case. As one of the peak temperatures, the melting temperature can be used corresponding to the fusion line, so that at least one characteristic peak temperature such as coarse grain zone, fine grin zone, intercritical zone, recrystallization, has to be determined by the simulation.Performed research showed that obtained values for heat input using Adam’s equation correspond pretty well with standard equation for heat input in arc welding.

Coset Enumeration

The Fibonacci group F(2, 7) has been known to be cyclic of order 29 for about five years. This was first established by computer coset enumerations which exhibit only the result, without supporting proofs. The working in a coset enumeration actually contains proofs of many relations that hold in the group. A hand proof that F(2, 7) is cyclic of order 29, based on the working in computer coset enumerations, is presented here.
