The Impact

Anthocyanins are secondary metabolites and water-soluble pigments belonging to the phenolic group, with important functions in nature such as seed dispersal, pollination and development of plant organs. In addition to these important roles in plant life, anthocyanins are also used as natural pigments in various industries, due to the color palette they can produce from red to blue and purple. In addition, recent research has reported that anthocyanins have important antioxidant, anticancer, anti-inflammatory and antimicrobial properties, which can be used in the chemoprevention of various diseases such as diabetes, obesity and even cancer. However, anthocyanins have a major disadvantage, namely their low stability. Thus, their stability is influenced by a number of factors such as pH, light, temperature, co-pigmentation, sulfites, ascorbic acid, oxygen and enzymes. As such, this review aims at summarizing the effects of these factors on the stability of anthocyanins and their degradation. From this point of view, it is very important to be precisely aware of the impact that each parameter has on the stability of anthocyanins, in order to minimize their negative action and subsequently potentiate their beneficial health effects.

Relevance of the article is based on participation of armed forces in various operations and exercises, where reliability of machinery is one of the most important factors. Transportation of soldiers as well as completion of variety of tasks is ensured by properly functioning technical equipment. Reliability of military vehicles – armoured SISU E13TP Finnish built and HMMWV M1025 USA built were selected as the object of the article. Impact of climatic conditions on reliability of the vehicles exploited in southwestern part of the Atlantic continental forest area is researched by a case study of the vehicles exploitation under conditions of the climate of Lithuania. Reliability of military vehicles depends on a number of factors such as properties of the vehicles and external conditions of their operation. Their systems and mechanisms are influenced by a number of factors that cause different failures. Climatic conditions represent one of the factors of operating load which is directly dependent on the climate zone. Therefore, assessment of the reliability is started with the analysis of climatic factors affecting operating conditions of the vehicles. Relationship between the impact of climatic factors and failure flow of the vehicles is presented and discussed.

Open Issues

The protein folded state is the result of the fine balance of a variety of different forces. Even minor structural perturbations may have a significant impact on the stability of these macromolecules. Studies carried out in recent decades have led to the convergent view that proteins are endowed with a flexible spine. One of the open issues related to protein local backbone geometry is the identification of the factors that influence the amplitude of the τ (N—Cα—C) angle. Here, statistical analyses performed on an updated ensemble of X-ray protein structures by dissecting the contribution of the major factors that can potentially influence the local backbone geometry of proteins are reported. The data clearly indicate that the local backbone conformation has a prominent impact on the modulation of the τ angle. Therefore, a proper assessment of the impact of the other potential factors can only be appropriately evaluated when small (φ, ψ) regions are considered. Here, it is shown that when the contribution of the backbone conformation is removed by considering small (φ, ψ) areas, an impact of secondary structure, as defined byDSSP, and/or the residue type on τ is still detectable, although to a limited extent. Indeed, distinct τ-value distributions are detected for Pro/Gly and β-branched (Ile/Val) residues. The key role of the local backbone conformation highlighted here supports the use of variable local backbone geometry in protein refinement protocols.

In different regions of the world, the growth in home broadband adoption and development of e-services depends on a number of factors which can decrease digital divide in size or can result in widened “gaps” between developed and developing economies as well as between rich and poor regions or social groups. These factors comprise both drivers of, and barriers to, development of broadband access and growth of e-services as well as human communication and digital interactions in terms of comprehension and relationship building (i.e., the successful collaboration in contemporary society). Using a human communication point of view, this chapter provides insight into a concept of information divide, specifies the distinction between digital and information divide, examines each of the factors that condition the mass-market broadband adoption, and considers the impact of techno economic stratification for the development of web-based e-services.

The Impact

The prenatal period is a vital process for the mother and father to become conscious about the development of the baby. Particularly in this process, in which mental and physical changes are observed in the mother, both the mother and father should be supported in order for the baby in the mother's womb to have a healthy gestation and to prevent a risky pregnancy. In this regard, particularly with the impact of recent technological innovations and with the increasing awareness of parents through increasing literacy, it is reported that the mortality rate is decreased; however, it is also reported that severe injuries during pregnancy and disabled babies still exist. From this point of view, the basic concepts related to development, developmental areas, developmental principles, factors affecting development and prenatal development will be explained in detail in the antenatal development section.

The Impact

Almost all crude oil used in Poland is imported. The domestic production meets less than 4% of needs; therefore, to ensure the security of supplies, Poland relies heavily on imports. It is worth mentioning, however, that Poland has crude oil resources oil fields are located in the Carpathians, Polish Lowlands, and in the economic zone of the Baltic Sea. For years, crude oil is imported mainly from the East, however, a significant change in this approach, leading to an increase in seaborne oil supplies, has been observed in recent years. In 2017, 77.3% of crude oil was imported from Russia, while the rest was supplied from Saudi Arabia, Iraq, Iran, Norway, and Kazakhstan. Increasing the diversification of supplies is, of course, a very positive phenomenon, because it allows reducing the dependence on one supplier, which is beneficial from the point of view of energy security. Taking into account a high dependence on oil imports, the article also discusses important factors affecting the global oil market: low investment in the upstream sector, a drastic decline in oil production in Venezuela, the impact of the U.S. embargo on Iran, or depleting oil reserves.

In the modern conditions of fulfilling professional duties, the issue of studying the personal and professional qualities of specialists of the Ministry of Emergencies of Russia has a special importance. Today, issues related to the study of the specifics of the professional qualities of specialists of the Ministry of Emergencies of Russia within the framework of scientific issues of modern psychology are of increasing importance. This is due to a number of factors, both the need for a deeper study of the principles of the formation of special skills and abilities, professionally important personal qualities of specialists of the Ministry of Emergencies of Russia, and insufficient scientific development, which puts these issues among the most relevant. We carried out analytical understanding of psychological and pedagogical literature on the topic. The theoretical and methodological analysis of the reliability problem indicates that it is not considered as an independent problem and is not established in the traditionally existing systems of selection, training, support of specialists. We considered the structure of reliability in the context of professional and personal qualities of specialists of the Ministry of Emergencies of Russia working in conditions involving danger to life. We gave an analysis of factors affecting the professional and personal reliability of a specialist of the Russian Emergencies Ministry. Personal and professional reliability of a specialist of the Ministry of Emergencies of Russia is a characteristic of personal features and qualities that determine the stability of reference normative behavior by indicators of personal reliability in professional activity. At the same time, another important parameter of personal-professional reliability is the moral and moral qualities of the specialist, his spiritual and moral maturity. We presented the results of research on the study of personal and professional qualities conducted with specialists of the Ministry of Emergencies of Russia.
