Introduction. The purpose of our work was to justify the need to improve the legislative, regulatory and methodological framework and preventative measures in relation to the spread of parasitic infections in the provision of medical care. There is a wide range of pathogens of parasitic infestations that are transmitted to humans through various medical manipulations and interventions carried out in various medical institutions. Contaminated care items and furnishings, medical instruments and equipment, solutions for infusion therapy, medical personnel’s clothing and hands, reusable medical products, drinking water, bedding, suture and dressing materials can serve as a major factor in the spread of parasitic infections in the provision of medical care. Purpose of research is the study of the structure and SMP of parasitic origin, circulating on the objects of the production environment in multi-profile medical and preventive institutions of stationary type in order to prevent the occurrence of their spread within medical institutions. Material and methods. The material for the study was flushes taken from the production environment in 3 multi-profile treatment and prevention institutions of inpatient type: a multi-specialty hospital, a maternity hospital and a hospital specializing in the treatment of patients with intestinal diseases for the eggs of worms and cysts of pathogenic protozoa. Results. During the 2-year monitoring of medical preventive institutions, a landscape of parasitic contamination was found to be obtained from the flushes taken from the production environment objects in the premises surveyed as part of the research work. Discussions. In the course of research, the risk of developing ISMP of parasitic origin was found to be determined by the degree of epidemiological safety of the hospital environment, the number and invasiveness of treatment and diagnostic manipulations and various medical technologies. Conclusion. It is necessary to conduct an expert assessment of regulatory and methodological documents in the field of epidemiological surveillance and sanitary and hygienic measures for the prevention of medical aid related infections of parasitic origin, to optimize the regulatory and methodological base, to develop a number of preventive measures aimed at stopping the spread of parasitic infections in the medical network.

Foundries in manufacturing plants are characterized by hazardous working conditions. The paper makes an assessment of industrial health hazards, identifies groups of diseases dominant among the examined individuals. It is clear that gastrointestinal diseases make the largest percentage. The effect of destabilizing industrial factors that lead to the intestinal biome restructuring, help reduce the dominant microorganism’s group and increase opportunistic flora has been determined. The severity of this indicator correlates with professional working experience. Along with the fecal matter bacterial flora of the examined people, the protozoa that belong to the parasitic group (blastocysts, lamblia, amoeba) were identified, and Blastocystis spp. has the largest proportion. The biological properties of blastocysts were studied exemplified by anticarnosine activity (AcrA), which allows them to colonize the intestinal mucous membranes and helps displace obligate symbiotes against the decrease in the overall resistance of the macroorganism. The data obtained make it possible to forecast human health state under the conditions of anthropogenic-disturbed territories and plan measures to improve and protect workers’ health.

The purpose of the research is studying the efficacy of Eprimek (Eprinomectin) against gastrointestinal nematodes in sheep.Materials and methods. A commercial experiment to study the antiparasitic efficacy of Eprimek was carried out in June 2020 on 300 lambs of the North Caucasian breed in a private flock of Filimonovskaya Village, Izobilnensky District, the Stavropol Territory, which were divided into two groups. The experimental group of lambs (290 animals) was injected Eprimek subcutaneously at the earset at a dose of 1 ml/50 kg of live weight (10 mg of Eprinomectin in 1 ml), and 10 lambs were not treated; they were used as control. We collected feces from the lambs of the experimental and control groups before administration of the drugs and after 15 and 30 days. Fecal samples were examined by the flotation technique with a saturated solution of ammonium nitrate with counting nematode eggs in 1 g of feces. The results were processed statistically.Results and discussion. Eprimek showed a decrease in the number of excreted helminth eggs from 225.1±28.2 to 4.1±2.3 in production environment at a dose of 1 ml/50 kg of live weight, according to coprological studies on the 15th day after treatment in the experimental group of lambs. The efficacy was 98.2%, and 70% of the animals were free from the infection. The intensity of infection of the control lambs by gastrointestinal nematodes was 131–151 eggs per 1 g of feces at 100% prevalence.

Introduction. The working conditions of pharmaceutical industry workers are characterized by the combined effect of unfavorable factors of the production environment, among which the leading one is chemical. The aim of study is to substantiate the basic principles and criteria for hygienic regulation of pharmaceutical products in their production to ensure safe working conditions for employees based on the results of their own research and existing requirements of technical regulations. Materials and methods. Analysis of working conditions and the prevalence of health disorders in pharmaceutical workers (according to literature data), toxicological studies of pharmaceutical substances on laboratory animals, scientific justification of hygiene standards in the air of the working area. Results. Among employees of the pharmaceutical industry, the predominant forms of production-related health disorders are diseases of the respiratory system, as well as skin dermatitis of allergic origin, liver and biliary tract diseases. Based on the results of experimental studies of domestic pharmaceutical products for the treatment of cardiovascular, oncological and mental diseases that have priority socio-economic significance, the basic principles and features of the practice of justifying the hygienic standards of medicines in the air of the working area are developed and systematized. Conclusions. During hygienic rationing of medicines, it is necessary to use a differentiated approach that allows, based on the analysis of information about the chemical structure, physical and chemical characteristics, production conditions, pharmacotherapeutic activity, and the results of studying the toxic effect in an experiment on laboratory animals, to determine the maximum permissible content in the air of the working area of medicines or to justify the prohibition of isolation with reasoned recommendations for their safe production.

This chapter concludes the volume with a study of Hollywood’s commercial approach to making musicals. Focusing on the 1936 movie adaptation of Anything Goes, the chapter looks at its production environment, one in which interpolations were common, song sales mattered more than wit, and risqué content was frowned upon, a combination that proved deadly for Porter’s score. Although some of Porter’s songs were retained, the studio’s music department head Nathaniel Finston assigned Leo Robin, Richard Whiting, and several others to write some new numbers for the film. In the context of a Hollywood in which studios capitalized on purchasing publishing companies and then copyrighting new songs by (usually, staff) Hollywood songwriters to in-house publishing firms, it is unsurprising for the chapter to conclude that faithful film adaptations are unlikely. Hollywood was devoted to commercial music while Broadway was divorced from it; and fidelity to Broadway’s canonized songwriters ran contrary to the commercial goals of Hollywood’s tunesmiths. Such tensions run throughout this book and help to explain the culture behind the unsettling but fascinating phenomenon of the stage-to-screen musical adaptation.

AbstractWith industries pushing towards digitalized production, adaption to expectations and increasing requirements for modern applications, has brought additive manufacturing (AM) to the forefront of Industry 4.0. In fact, AM is a main accelerator for digital production with its possibilities in structural design, such as topology optimization, production flexibility, customization, product development, to name a few. Fused Filament Fabrication (FFF) is a widespread and practical tool for rapid prototyping that also demonstrates the importance of AM technologies through its accessibility to the general public by creating cost effective desktop solutions. An increasing integration of systems in an intelligent production environment also enables the generation of large-scale data to be used for process monitoring and process control. Deep learning as a form of artificial intelligence (AI) and more specifically, a method of machine learning (ML) is ideal for handling big data. This study uses a trained artificial neural network (ANN) model as a digital shadow to predict the force within the nozzle of an FFF printer using filament speed and nozzle temperatures as input data. After the ANN model was tested using data from a theoretical model it was implemented to predict the behavior using real-time printer data. For this purpose, an FFF printer was equipped with sensors that collect real time printer data during the printing process. The ANN model reflected the kinematics of melting and flow predicted by models currently available for various speeds of printing. The model allows for a deeper understanding of the influencing process parameters which ultimately results in the determination of the optimum combination of process speed and print quality.
