Abstract: Introduction. The development and improvement of mechanisms for assessing and predicting occupational injuries, both in the short term and for a long period of time, is a key task in the field of occupational safety for each branch of economic activity. Aim is to determine the list of the most characteristic initial data and parameters for predictive assessment of occupational injuries and accidents of various severity. Research methods. Comparative analysis of various models for assessing and predicting injuries is carried out. Based on the methods of expert analysis, the advantages and disadvantages of each of the methodological approaches are evaluated and the most characteristic initial data for predictive assessment of occupational injuries are highlighted. Results. Necessity of taking into account the complexity of the causes of accidents is established and the most common parameters that are used as initial data for predicting accidents of various severity are determined, which include: profession, employee training, level of training, age, length of service, number of violations.

This chapter describes occupational injuries and their prevention. It describes in detail the causes of injuries and epidemiology of injuries. Occupational injuries are caused by acute exposure in the workplace to safety hazards, such as mechanical energy, electricity, chemicals, and ionizing radiation, or from the sudden lack of essential agents, such as oxygen or heat. This chapter describes the nature and the magnitude of occupational injuries in the United States. It provides data on risk of injuries in different occupations and industries. Finally, it discusses prevention of injuries, using a hierarchical approach to occupational injury control.

The paper investigates and explains a new simple analytical tuning of proportional-integrative-derivative (PID) controllers. In combination with nth order series binomial low-pass filters, they are to be applied to the double-integrator-plus-dead-time (DIPDT) plant models. With respect to the use of derivatives, it should be understood that the design of appropriate filters is not only an implementation problem. Rather, it is also critical for the resulting performance, robustness and noise attenuation. To simplify controller commissioning, integrated tuning procedures (ITPs) based on three different concepts of filter delay equivalences are presented. For simultaneous determination of controller + filter parameters, the design uses the multiple real dominant poles method. The excellent control loop performance in a noisy environment and the specific advantages and disadvantages of the resulting equivalences are discussed. The results show that none of them is globally optimal. Each of them is advantageous only for certain noise levels and the desired degree of their filtering.

BACKGROUND: Mining, especially underground coal mining, has always been a hazardous occupation. Injuries, including those that are fatal, are a major occupational risk that all miners have to face. OBJECTIVE: Despite the fact that all workers are aware of the risks, efforts must be made to increase their safety through the implementation of preventive measures. METHODS: This retrospective study includes injury data from all nine Serbian coal mines over a 16-year period, from 2000 to 2016. All injury data were collected from employee safety and health records. RESULTS: In the analyzed period, a total of 9,273 occupational injuries were recorded at Resavica. The highest number of occupational injuries (over 600) were recorded in 2008 (669), 2004 (651), and 2005 (603). The data shows that almost one fifth of the total number of occupational injuries, or 20.74%, occurred during the said three years. On average, 493.06 minor, 51.12 severe, and 1.29 fatal injuries occurred each year. Every day there were 1.29 minor occupational injuries and every seven days there was one severe injury. CONCLUSIONS: Despite indications that there is a connection between some of the variables and the number of injuries, the general conclusion is that injuries are accidental and unpredictable. The high percentages of injuries are due to the organization of work and the age or qualification structure of the staff and, of course, are the consequence of likelihood –the greater the number of workers, the greater the likelihood of injury. However, the present study showed that some measures can be taken to increase occupational safety and reduce the number of injuries.

This paper presents basic information on a structure and function of biological membranes. Types of biomimetic membranes modelling properties of biological membranes were introduced. The method of testing surface properties of a lipid monolayer, which is the basic type of biomimetic membranes, was described. The presented method makes it possible to evaluate the effect of nanoparticles on the surface activity of biomimetic membranes based on the determination of the surface index MA. This article discusses the problems of occupational safety and health, which are covered by health sciences and environmental engineering.

This article analyzes the choice-of-law interests of specific and potential participants in the relations of intellectual property rights and the state in order to establish the closest connection of the above type of relation with the state, whose law should be applied. Taking into account the directionality of significant choice-of-law interests, advantages and disadvantages of territorial and universal approaches, a theoretically based solution is proposed for the formation of a general choice-of-law rule on the law to be applied to the relation of intellectual property rights. It was revealed in the study that the diversity of the relations of intellectual property rights (their obligatory and non-obligatory, property and personal non-property nature, other differences in legal features) does not automatically generate a multidirectionality of significant choice-of-law interests that should be taken into account when establishing a close connection of the above type of the relation with the state for determination of applicable law, does not prevent the formation of a general choice-of-law rule for the relations of intellectual property rights in general and does not unequivocally testify in favor of the specialization of its binding. However, the diversity of the relations of intellectual property rights should be examined and evaluated for the feasibility and limits of exceptions from the general choice-of-law rule and the development of special rules for resolving certain private of the relations of intellectual property rights.

According to the World Health Organization (WHO), 71 million people were living with Hepatitis C virus (HCV) infection worldwide in 2015. Each year, about 399,000 HCV-infected people succumb to cirrhosis, hepatocellular carcinoma, and liver failure. Therefore, screening of HCV infection with simple, rapid, but highly sensitive and specific methods can help to curb the global burden on HCV healthcare. Apart from the determination of viral load/viral clearance, the identification of specific HCV genotype is also critical for successful treatment of hepatitis C. This critical review focuses on the technologies used for the detection, discrimination, and genotyping of HCV in clinical samples. This article also focuses on advantages and disadvantages of the reported methods used for HCV detection, quantification, and genotyping.

AbstractUnderstanding the growth of whiskers or high aspect ratio features on substrates can be aided when the crystallography of the feature is known. This study has evaluated three methods that utilize electron backscatter diffraction (EBSD) for the determination of the crystallographic growth direction of an individual whisker. EBSD has traditionally been a technique applied to planar, polished samples, and thus the use of EBSD for out-of-surface features is somewhat more difficult and requires additional steps. One of the methods requires the whiskers to be removed from the substrate resulting in the loss of valuable physical growth relationships between the whisker and the substrate. The other two techniques do not suffer this disadvantage and provide the physical growth information as well as the crystallographic growth directions. The final choice of method depends on the information required. The accuracy and the advantages and disadvantages of each method are discussed.

A method for the X-ray determination of lattice-plane distances is given. Similar to Bond's method, it is based on the measurement of rocking curves, with some advantages and disadvantages compared with the former method. The new method is especially designed for single-crystal stress measurement. Its usefulness is demonstrated in two examples of lattice-constant and stress measurement.
