Authors: Vitaly Tsopa  , Serhii Cheberyachko  , Yurii Cheberyachko  , Oleg Deryugin  , Nadiia Sushko
Published: July 2023

Purpose. To justify the procedure for developing scales for building a matrix of professional risk assessment.

Methodology. To build a professional risk assessment matrix, we used the recommendations given in DSTU ISO 73:2013 “Risk Management. Glossary of terms (ISO Guide 73:2009 Risk management – Vocabulary), in which, in order to build a matrix of professional risks, it is assumed to determine the category of consequences of a dangerous event with an assessment of their plausibility and the frequency of occurrence of a dangerous event, which allows determining the “probability” scale.

Results. An approach to building a matrix of professional risks has been developed, which consists of three main stages: the first is defining the terms and concepts of the matrix of professional risks and their understanding; the second is determining the value of the scale of frequency (or probability) and severity of the consequences of a dangerous event (incident) with full understanding by company employees of the requirements for their assessment and use, based on statistical data and medical definitions of the type and type of injuries, stages of occupational diseases; the third is defining criteria for assessing occupational risks in accordance with standards, laws, policies, experience and specific requirements set by the organization itself (for example, to achieve a level of “zero” injuries). An example of the assessment of the professional risks of a turner’s job of processing a shaft blank with the development of appropriate forms for assessing the frequency (probability) of the occurrence of a dangerous event (injury of an employee’s limb) and the severity of the consequences (limb fracture) for risk calculation and its documentation is given. The main causes of the dangerous event that occurred with a turner due to the worker’s sleeve being caught were determined. The risk assessment algorithm is described, which consists of five steps: identification of the hazard, determination of the frequency or probability of occurrence of a dangerous event and the severity of the injury, assessment of occupational risks, substantiation of precautionary measures and verification of the obtained risk value.

Scientific novelty. The approach to the calculation of professional risk is substantiated by determining the frequency of occurrence of a dangerous event and the severity of the consequences of its occurrence, with the justification of risk management actions.

Practical significance. The proposed template of a typical professional risk matrix with criteria for scales of the frequency of occurrence of a dangerous event and the severity of its consequences.
ASSESSMENT OF THE STABILITY OF MINE HAULAGE DRIFT USING STATISTICAL ANALYSIS OF ARCH YIELDING SUPPORT FAILURE
Authors: Volkov Serhii , Boichenko Hennadii
Published: July 2023

Purpose. The stability of mine haulage drift has been evaluated using statistical analysis of arch yielding support failure under different protective measures to create safe working conditions for miners in deep coal mines with steeply dipping seams.

Methods. A comprehensive approach was used, including a mine experiment , probability theory methods, and statistical analysis of experimental data.

Results. The stability of mine haulage drift on steep seams was assessed in natural conditions under different protective measures. It was found that while using post-and-lintel support to protect the drift, with an arch yielding support failure frequency of w≥0.56 and normal distribution of single-factor dispersion analysis statistics, the loss of cross-sectional area of the excavation over the length of the mining site was about 50%. While using cribbing support for protection, with an arch yielding support failure frequency of w≥0.29, the loss of cross-sectional area was 30%. Empirical frequency w of the arch yielding support failure along the length of the excavation does not differ from theoretical frequencies, allowing the probability of an event related to deterioration of the stability of the mine haulage drift along the length of the mining site to be determined within a confidence interval under different protective measures.

Novelty. A functional dependence was established to evaluate the stability of the mine haulage drift under different protective measures along the length of the mining site using single-factor dispersion analysis statistics of arch yielding support failure.

Practical significance. Based on the statistical analysis of arch yielding support failure installed in the mine haulage drift, it is advisable to consider that the operational condition of the preparatory workings is ensured when using protective structures in the form of wooden cribbing support.
STUDY OF DEFORMATION PROPERTIES OF PROTECTIVE STRUCTURES OF PREPARATORY MINING WORKS
Authors: Hryhorets Maksym , Tkachuk Oleksandr , Pahomov Serhii , Vasilenko Volodymyr , Podkopaiev Serhii
Published: July 2023

Purpose. To study the stability of the security structures of the preparatory mine roadways of steep seams while unloading the coal-rock massif to prevent the collapse of side rocks in the excavation areas of the coal mine and create safe working conditions for miners.

Method. In order to achieve the aim of the research, the study of the stability of security structures was carried out at the laboratory of mountain pressure by using experimental samples in the form of whole coal and structures consisted of crushed rock, which were subjected to uniaxial compression.

Results. Under the conditions of uniaxial compression of whole coal or constructions consisted of crushed rock, with the ratio of length to width a/b= (1-2) and an increase in the cross-sectional area S (m2) of the experimental samples, a relative change of their volume δV was observed. For whole coal, the steady state is ensured by the relative volume change δV ≤ 0,1. Beyond the set value of δV, the whole coals lose their stability and collapse, which results in the collapse of the side rocks. For the crushed rock structures, with an increase in the cross-sectional area of the compressible specimens, the relative volume change decreases from δV = 0,2 to δV = 0,35. At the same time, the crushed rock is compacted in the whole volume of the used material, the bearing capacity of protective structures is increased, which enables limiting the movement of lateral rocks and ensures their integrity.

Scientific novelty Within the limits of the deformation resource of protective structures consisting of crushed rock of different granulometric composition, with their uniaxial compression, a type of functional dependence was established, which enables us to estimate the relative change in the volume of flexible supports from stiffness, which is necessary for assessing their bearing capacity.

Practical significance. In order to create safe working conditions for miners in the excavation areas of a deep coal mine and prevent the collapse of side rocks in the coal massif, it is advisable to use flexible protective structures for the protection of preparatory coal mine roadways, when the ratio of their linear dimensions corresponds to the ratio of length to width of a/b>(1-2).

Published: July 2023

Objective: to analyze working conditions and safety of miners involved in mining excavations by drilling and blasting and to develop modern schemes and technical solutions to improve their standards.

Methodology: comprehensive and detailed analytical studies of the current problems connected with occupational health and safety of personnel working specifically in lifting mine excavations of different purposes were carried out, on the basis of which the key tasks for their practical solution were defined.

Results: The preliminary analysis and analytical studies have determined that the main and most acute problems requiring an urgent solution are connected with the ventilation of mine workings, and the need to improve the means of sampling and express-control of the quality of air from the bottom-hole zone of mines. According to the state standard “System of product development and launching into manufacture” (“DSTU 3974-2000”) the fundamentally new integral system of schemes and technical solutions (having no analogs) was developed. The system allows for efficiently and reliably solving the extremely complicated issues of ventilation, dust and gas removal, air quality sampling, and control (express analysis) of air composition in drilling and blasting mining excavations of different purposes (ore mining, ventilation, material-entry) to the height of 80-100 m. The developed equipment includes a multipurpose high-pressure ejector-type automatic dust collector ADC-1, designed for efficient ventilation of lifting workings and providing normal sanitary and hygienic working conditions for tunnelers while performing their work cycle, and for reliable neutralization of explosion products; the modernized device for remote control of air composition RCAC-20/80 ore-welding ventilation and material-entry from the bottom-hole zone of the lifting excavations. This process can be carried out both with the use of standard special indicator tubes with chemical reagents and with the use of modern electronic gas-measuring apparatuses (“Dräger-2500/5000” made in Germany or their analogs).

Scientific novelty: the integration, i.e. bringing into a single system, of developed up-to-date technical solutions for effective ventilation, reliable dust and gas extraction, gas removal, and air quality sampling and control of air composition of the lifting workings by the drilling and blasting method.
DETERMINATION OF CONTROL FACTORS AFFECTING THE PROBABILITY OF A SUDDEN OUTBURST OF COAL AND GAS IN A BREAKAGE FACE
Authors: Khorolskyi Andrii  , Kosenko Andrii  , Sai Kateryna  , Petlovanyi Mykhailo
Published: July 2023

Purpose. To establish priority (control) factors affecting the probability of a sudden outburst of coal and gas in a breakage face, which will allow making optimal technological decisions when mining outburst-prone coal seams.

Methods. An integrated method that involves the use of energy-force models to assess the likelihood of sudden outbursts of coal and gas; application of simulation modelling to determine priority control factors; application of an algorithm for enumeration of discrete values for each parameter, to find the average value of the increment of potential energy in a unit volume of coal in the working area of the longwall machine; application of dynamic programming to substantiate technological parameters (seam thickness, web width cutter-loader, length of a breakage face, etc.) mining of outburst-prone coal seams.

Results. A mathematical model has been developed for the excitation of a sudden outburst of coal and gas, based on the energy theory of the occurrence of a sudden outburst of coal and gas. According to this model, the main sources of energy leading to the destruction of the seam are the energy of elastic deformation of the coal seam, the potential and kinetic energy of rocks, the internal energy of free and desorbed gas. On steeply falling seams, additional energy sources are the gravitational energy (positional energy) of the coal seam. The developed model allows establishing priority control factors and study the patterns of their change. Based on the setting of priority control factors, it is possible to choose the optimal technological schemes for mining outburst-prone coal seams.

Scientific novelty. The scientific novelty consists in determining the priority control factors that affect the possibility of a sudden outburst of coal and gas, as well as establishing the pattern of their change. For this, a simulation algorithm was developed, which made it possible to establish the essential parameters of outburst-prone coal seams. Based on the algorithm for estimating the probability of a sudden outburst of coal and gas, the optimal technological parameters for mining of outburst-prone coal seams (web width, length of a breakage face, rate of advance) were determined.

Practical implication. It consists in creating a package of applications for the selection of treatment equipment in accordance with certain technological solutions. On the basis of the data obtained, the optimal technological schemes for the mining of outburst-prone coal seams are substantiated, and mechanization means are selected based on the application of a package of applied programs.

Authors: Sodré Debora , De Lima Mayara Martins , Da Silva Vitória Milena , Rodrigues Denise
Published: July 2023

Abstract: The aim of this study was to report a case of male pseudohermaphroditism in a French Bulldog that had testicles, vulva and poorly developed penis. Intersexuality or hermaphroditism is a concept that refers to anomalies present from birth in animals that have ambiguous sexual characteristics, that is, that do not clearly fit as male or female. These anomalies can be divided into two main categories: true hermaphrodites and pseudohermaphrodites. An individual is considered a male pseudohermaphrodite when he has female sexual characteristics, but has testicular gonads. Male pseudohermaphroditism is the most common form of intersexuality in domestic animals, characterized by the presence of the XY chromosome and testes in the abdominal cavity. In veterinary medicine, it is common to find cases of intersexuality in dogs, the most frequent form being pseudohermaphroditism, while true hermaphroditism is rare. Thus, it was concluded that the present report plays a significant role in contributing to the dissemination of a specific case of intersex, more precisely male pseudohermaphroditism.

Authors: Fidencio Maestrello Julia , Penegossi Mariele
Published: July 2023

The occurrence of gastrointestinal parasites in cats is reported with great frequency, especially when it comes to animals with outdoor access, or living in overcrowded environments, such as catteries and shelters. Infection byIsospora spp in cats begins with the ingestion of sporulated oocysts in the environment or tissues from other infected intermediate vertebrate hosts. Diagnosis is based on the detection of oocysts in cat feces and clinical signs. The recommended treatment for coccidiosis in cats is sulfonamides. Other drugs have been studied as secondary lines of treatment, which is the case of ponazuril and toltrazuril, which have been used in animals to treat isosporosis, toxoplasmosis, neosporosis and equine protozoal meningoencephalitis. There are anecdotal reports of the use of ponazuril in treating Isospora spp. In this study, 21 cats were treated with ponazuril, which proved effective in controlling the disease, since 100% of the cats treated were negative in the coproparasitological examination after the three days of treatment with a dose of 50 mg/kg SID. Furthermore, the animals had considerable improvement in stool consistency after the dosing period.

Objetivo deste estudo foi avaliar o desenvolvimento de plantas do feijão-Caupi (BRS guariba), plantadas com substrato e adubadas com esterco bovino e esterco de aves. Foi utilizado o delineamento em blocos inteiramente casualizados, sendo sete blocos e três tratamentos. As sementes foram inicialmente plantadas em bandejas próprias para produção de mudas no dia 31/10/2022. seis dias após a germinação as mudas foram transferidas para vasos com capacidade de oito litros de substrato próprios para cultivo da cultivar. Foi usado sombrite de 75% de sombreamento. A rega acontecia sempre duas vezes por dia, uma no período da manhã e outra no período da tarde. A medição das alturas das mudas foi realizada no dia 22/11/2022. Sendo que foi utilizado apenas uma semente por vaso, ocorrendo na perda da parcela do tratamento dois no bloco três, portanto, o experimento será analisado como parcela perdida, acarretando assim na perda de um grau de liberdade para o resíduo. Os tratamentos foram: T1 areia (testemunha), T2 esterco bovino e T3 esterco de aves. Os resultados obtidos nas análises estatísticas mostram efeito significativo para a variável altura de plantas de feijão Caupi aos dias 30 dias pós semeadura, uma vez que o valor da estatística F (33,17) supera o valor critico o nível de 5% de probabilidade (19,40) ele é significativo nesse nível (P < 0,05). Com isso rejeitamos a hipóteses nula H0 e concluímos que existe diferença entre os efeitos dos tratamentos avaliados. Para a fonte de variação blocos o valor da estatística F (0,83) é inferior ao valor crítico no nível de 5% de probabilidade (4,03). O teste foi não significativo nesse nível (P > 0,05), logo, não se pode rejeitar a hipóteses nula H0. Concluímos que o fator controlado por blocos não influi diretamente no desenvolvimento das mudas de feijão Caupi. Dentre os tratamentos avaliados, o esterco de aves (T3) mostrou efeito significativo em relação aos demais, apresentando uma média de 27,6 cm enquanto os tratamentos (T1) e (T2) não difiram entre si segundo o teste de Tukey a 5 % de probabilidade. Concluímos que para a altura média das plantas de feijão caupi, apresentou resultado significativo com a adição de esterco de aves T3, os demais tratamentos T1 e T2 apresentaram resultados semelhantes. O experimento apresentou um coeficiente de variação na anova corrigida para parcela perdida de 4,66, indicando uma boa precisão na implantação e condução do experimento.

This literature review aimed to analyze the psychological symptoms caused by digital dermatitis in dairy cattle. Digital dermatitis (DD) is one of the main causes of infectious lameness in dairy cattle, generating a significant impact on the production and well-being of the animal. It is a contagious disease, caused by various microorganisms, with a predominance of bacteria of the genus Treponema, but bacteria such as Fusobacterium necrophorum, Dichelobacter nodosus and Porphyromonas levii have also been identified. It is characterized by ulcerative lesions along the coronary band or on the skin adjacent to the interdigital cleft in cattle. Clinical signs are nonspecific but, in general, they present as claudication, which can vary from mild to severe, reluctance to move, kyphosis posture to distribute body weight onto a more comfortable position, shorter strides, walking on the tip of the digit or even putting no weight on the affected digit at all. Diagnosis is made by inspecting the foot, but techniques such as serological testing and molecular diagnosis are being studied and have proven to be viable tools as an alternative to clinical inspection. The main objective of the treatment of DD is to reduce bacterial infection. Three main approaches are described in the literature: systemic antibiotics; individual topical treatment and group footbath treatment. Economic impacts are caused by the behavioral changes brought on by the pain, which leads to a reduction in milk production and fertility of these animals, in addition to costs with treatment, control, eradication and premature disposal of animals due to the chronicity of the disease. Based on these studies, it is concluded that DD represents a negative economic impact on milk production and animal welfare.

Traumatic diaphragmatic rupture is a frequent emergency condition in small animals. The present work gathered studies that point to male, young and non-neutered cats as the most susceptible to it, especially those with outdoor access. Direct or indirect trauma causes the diaphragm to rupture, causing the abdominal organs to migrate into the thoracic cavity, and severe damage to the cavity and thoracic organs can occur as a result of the trauma. Clinical signs may include dyspnea, cyanosis and muffled cardiopulmonary sounds on auscultation. However, the signs may be nonspecific depending on the severity and time of rupture. Treatment is surgical, and a diaphragmatic herniorrhaphy procedure is indicated, consisting of the synthesis of the diaphragm where it was ruptured to recompose its anatomical structure, restoring its function in breathing and reestablishing the negative pressure of the thorax.

Traumatic hip dislocation consists of displacement of the femoral head in relation to the acetabular fossa resulting from trauma. The main orthopedic disorders are due to external trauma, which may result in hip dislocations, fractures of the femoral head and neck, and acetabular fracture. Presentation changes according to the types of dislocation, which are classified as craniodorsal, caudodorsal, ventral, ventrocaudal and ventrocranial. In this way, the objective of this work is to report and discuss the case of a canine with caudoventral dislocation treated with the colocephalectomy technique after the occurrence of domestic trauma. We describe the case of a canine, male, not castrated, 2 years old, seen at the Adílio Santos de Azevedo Veterinary Hospital, presenting a history of trauma after a home accident with the presence of claudication and rotation of the right pelvic limb. After specific clinical examination and X-ray of the pelvic limb, right caudoventral coxofemoral luxation was diagnosed. The animal was diagnosed with caudoventral luxation, which is rarely seen in the routine of medical and surgical clinics for small animals. It occurs in approximately 1.5 to 3.2% of cases, making it a rare occurrence. In addition, it was observed that a rate of 20% of animals that present coxofemoral luxation have concomitant traumas. In this report, the animal did not suffer any type of associated trauma or muscle laceration. Ventrocaudal coxofemoral luxation is rare in dogs, and the femoral colocephalectomy technique was successfully applied in the patient without trans- and postoperative complications.

Fibrosarcoma is a malignant mesenchymal tumor classified as the third most common oral tumor in dogs. It is a locally aggressive and invasive neoplasm, with a low metastasis rate if identified early. The recommended treatment is total resection with a safety margin in order to avoid recurrence, as it is common with this oral tumor. The present work aims to report a case of this condition in a mixed breed canine, nine years old, who had significant periodontal disease, gingival bleeding, and an increase in volume on the inner side of the right labial commissure. The tumor appeared as a firm and rounded lump, with signs of inflammation. Cytology was performed for diagnostic purposes, which was compatible with mesenchymal neoplasia. Thus, total surgical resection was performed as treatment, with adequate margins, associated with reconstructive surgery due to lack of sufficient tissue to achieve suture and surgical closure. Histopathological analyses resulted in a tumor process compatible with fibrosarcoma. After follow-up and removal of the stitches, the animal was referred to the veterinary oncologist for further investigation.
