Opis:
One of the basic stages of mining operations is development work. During them there can occur the events that affect the process of development work as well as the safety of workers. This article conducts a process risk assessment using the Failure Modes and Effects Analysis (FMEA) method to identify events that disrupt the development work process, along with the causes of the occurrence of these events. The study covered the process of development work i.e. the execution of the M-2 roadway in seam 502/1 realized at a depth of about 550 m with an assumed length of about 500 m. As a result of the study, those risks for which countermeasures should be applied were identified, and measures were proposed to minimize the risks involved. As part of the research, an FMEA evaluation form was created to assess process risks in the execution of similar work. The highest process risk was identified for the drivage of the excavation with a road header, and is related to the possibility of frequent failure of hydraulic systems. Similar process risk results were obtained for the risk associated with improper execution of mining with explosives and the need to perform additional blasting work in the excavated roadway. The results can contribute to reducing the time of coal face stoppage during development work, and thus improve the process of them and reduce the costs incurred during this process.

Opis:
This study is based on the assumption that the primary aim of the emergence of states was to provide security and development opportunities for its citizens. This objective determines the method of exercising power, the applicable legal system reflecting the adopted norms of social coexistence, and the public administration system. It was also presumed that security is associated with a sense of threat and confidence. They can be both objective and subjective, which means that they can be measurable or not. Due to the fact that while there are no major problems with determining the definition of a state, there are still difficulties related to identifying the essence of security and, consequently, also the security of the state. Therefore, the paper is based on the results of the bibliographic method and presents an overview of representative outlooks on issues related to threats, security and national security. This was done by reference to works created on the basis of the law, political sciences, and security sciences. The work was divided into three parts. The first introduces the considerations. The second presents views allowing the nature of security to be determined, and the third part presents the subject-entity scope of state security and the determinants of that security.

Opis:
The purpose of this article is to identify and assess environmental risks that may have the greatest impact on the future of humanity. They were divided into two basic groups, i.e. for natural processes and resources. In addition, climate change is described as different group. The authors decided, that a holistic approach to this issue is more desirable than dividing it into two above-mentioned groups. The comparison of various threats was possible due to the application of identical assessment criteria, such as: the harmfulness, rate of spread, scope and moment of occurrence of a given group of threats. Each of the listed criteria has been evaluated on a fi ve-point scale, where 1 has the smallest and 5 the largest impact force. The obtained results show the leading importance of natural processes in maintaining the existing Earth system. In addition, the authors point to a greater risk of problems related to renewable resources than non-renewable one. As a result, it can be assumed that the current degradation of natural processes and excessive use of resources is likely to lead to the risk of global disasters.

Opis:
Recent literature data reveals the most common etiological agents of congenital parasitoses to be Toxoplasma gondii, Trypanosoma cruzi, Leishmania donovani and Plasmodium falciparum. An analysis of clinical data indicates that parasitic congenital infections are often asymptomatic, whereas symptomatic newborns usually display nonspecific symptoms, which greatly hinders correct diagnosis. The long-term consequences of prenatal infections are serious clinical problems. This article presents the possible routes of vertical transmissions (mother-to-child) of pathogens including prenatal, perinatal, as well as postnatal routes. It highlights the role of factors involved in protozoa transmission and development of congenital parasitic diseases, such as parasite genotypes, the relationship between the timing of maternal infection and the probability of passage of the parasite through the placental barrier, and the immunological features of pregnant women. Acquired and congenital babesioses in human and experimental animals are presented. It emphasises that the mechanisms by which parasites infect the placenta and cross from mother to fetus are still poorly understood. It also describes the cellular mechanisms of infection by T. gondii, such as tachyzoites crossing biological barriers, the expression of Toll-Like Receptors (TLR) family on trophoblasts and syncytiotrophoblasts as an immune response to intrauterine infection and cases of congenital and acquired toxoplasmosis, as well as the long-term consequences of congenital invasion with T. gondii, episodes of reactivation of latent toxoplasmosis and T. gondii reinvasions. Mycological topics include a rare case of in utero fungal infection of offspring by a mother with vaginal candidosis, and the fungal contamination of ward facilities and medical equipment as potential sources of exogenous infections of newborn children.
