Opis:
Objectives: The aim of this study is to determine the activities of different countries in the context of the Syrian conflict. Methods: The following research methods and techniques have proven to be useful: starting material analysis, cause-effect analysis, scientific observation. Results: An analysis of the available literature has shown that the Russian Federation has refrained from direct participation in the war in Syria since the beginning of the war. First, it supplied arms and ammunition to Syria to support the Assad regime, and in Damascus and other areas, Russian trainers were deployed to support Assad’s war efforts. But in the fall of 2015, when Assad’s government forces were severely weakened, Russia began to implement direct and open military support on the scale of a world power with global ambitions. Conclusions: The political-military measures of the Russian Federation had enormous destabilizing effects on the entire region of the Middle East. The strategic interests of many countries in the region are under threat, and the Russian Federation has become and will continue to be an important player in the Middle East. Russia’s engagement in Syria is part of the Russian Federation’s multifaceted policy aimed at achieving various objectives. The Russian operation in Syria is Russia’s return to the Middle East Games as an important military and political player with the aim of strengthening its own position and weakening the position of the United States. With its military actions in Syria, Russia has reaffirmed its influence in the Middle East region.

Opis:
Studies of effiiency of several methods for calculating the interaction potential of a pair of two-dimensional hard cyclic multimers - molecules formed by hard disks (atoms) placed at the vertices of a regular polygon - are reported in this work. Such hard-body particles, known as hard cyclic multimers, constitute a class of important reference systems in modeling structural and thermodynamic properties of molecular systems. A new method is proposed which can be easily implemented to Monte Carlo simulations of two-dimensional cyclic multimers and which is faster than the fastest method used previously.

Opis:
This work presents the methodology of the Russian impact on Latvia after 1991. It defines and specifies the scope of methods concerning both the hard and soft power in international relations in the 21st century, particularly the ones used to implement the Russian Federation’s foreign policy. The implemented strategies and impact models are described. The work is also focused on certain indicators used in global rankings by experts worldwide. In the 21st century, it is no longer enough to employ the hard power methods as it is advisable to use the soft power ones, which may bring about much better results than the hard ones.

Opis:
Concentrations of seventeen unsubstituted polycyclic aromatic hydrocarbons (PAHs) have been determined in hard coal samples from the Carboniferous Upper Silesian, Lower Silesian and Lublin Coal Basins. Among the investigated coals the highest average content of PAHs was determined for the Lower Silesian coals - 6.619 ppm, whereas the means for the Upper Silesian and Lublin coals were 4.11 and 4.319 ppm respectively. Hard coals from the Lublin Coal Basin have relatively high contents of the 5- and 6-cyclic hydrocarbons and lower contents of the 3-cyclic hydrocarbons (0.180 ppm) than coals from the Lower Silesian and Upper Silesian Coal Basins, which contain 2.542 and 1.437 ppm respectively. Within the Upper Silesian Coal Basin there are differences in the PAH "profiles": the coals from the eastern part of the basin have higher contents of the 5- and 6-cyclic aromatic hydrocarbons and lower contents of the 3-cyclic hydrocarbons than those from the western part of the basin.

Opis:
The influence of the chemical composition of selected armature brasses on the formation of hard inclusions was investigated. In metallographic studies using optical microscopy and scanning electron microscopy with X-ray microanalysis (EDS), it was found that hard inclusions attain sizes ranging from several hundred nanometers to several micrometers. Investigations of samples that were taken from metallurgical pigs of armature brass of various chemical compositions have shown that the contribution of components such as iron and silicon have a decisive influence on the formation of hard inclusions. These components have a dominant share in hard inclusions (60–76 wt.% Fe and 10.6–17.4 wt.% Si). In much smaller quantities there are also elements such as manganese, phosphorus, nickel and chromium. The chemical composition of hard inclusions varies. The number and size of hard inclusions depends on the contribution of iron and silicon brass. In the brass sample with 0.31 wt.% Fe and 0.08 wt.% Si, 1183 inclusions per square millimeters were identified, while in the brass sample with 0.21 wt.% Fe and 0.11 wt.% Si the amount of hard inclusions was reduced to 933 inclusions per square millimeters. In the brass sample with reduced iron content up to 0.08 wt.% and silicon up to 0.006 wt.%, no hard inclusions were identified.

Opis:
Internet users mainly consider ‘hardcore’ in connection with something extreme (eg. sports), which ensures maximum intensity of dangerous experience or resistance to change. ‘Hardcore’ is also name of the style in music, which in the 1980s was initiated by the second wave of punk bands. At the same time it applies to the genre of electronic music. Inhomogeneous concept of hardcore is associated with its earlier use than those that we now know. The word ‘hardcore’ was also used as the name of a base for road construction (eg. small stones, pieces of brick and grits), and/or to describe difficult/extreme physical exercise. However, before the term ended up in the language of culture, it was an economic term, meaning people who were not only unemployed, but those unemployed who have been out of work for a year or longer. The word appears in the Oxford English Dictionary (1936) in a phrase ‘hard-core unemployment’ (hard core of unemployed) which can be traced to the difficult situation of people. In general, the first time it appears in 1930 in the texts by Irish parliamentarians. Then, after 1950, it is more often used to determine former prisoners, terrorists (pro-segregation), people addicted to hard drugs, and even ... Republicans. Associations with ‘hard’ pornography or hardcore bands of music meant that deadline was not included in the art and did not function as an aesthetic category. At the same time hardcore, in all its manifestations, the term exists because of its diverse literary layer, as ‘cute’ word, and many references that make it difficult to ignore.

Opis:
Hard turning is a machining process that is widely used in the precision mechanical industry. The characterization of the functional surface texture by the ISO 13565 standard holds a key role in automotive mechanics. Until now, the impact of cutting conditions during hard turning operation on the bearing area curve parameters has not been studied (ISO 13565). The three parameters Rpk , Rk and Rvk illustrate the ability of the surface texture to resist friction. In this work, the main objective is to study the impact of cutting conditions (Vc, f and ap) of the hard turning on three parameters of the bearing area curve. The statistical study based on response surface methodology (RSM), analysis of variance (ANOVA) and quadratic regression were performed to model the three output parameters and optimize the input parameters. The experimental design used in this study is the Taguchi L25 orthogonal array. The results obtained show that the cutting speed has a greater effect on the bearing ratio curve (Rpk , Rk and Rvk ) parameters with a percentage contribution of 37.68%, 37.65% and 36.91%, respectively. The second significant parameter is the feed rate and the other parameter is significant only in relation to Rpk and Rk parameters.

Opis:
The United States, as a leading world power, has to face China – an emerging powerful rival. The potential of both states’ power is measured by universal indicators. On a military level, these indicators are: military expenditure, soldiers/reserve/soldiers abroad, offensive weapons, nuclear warheads. On an economic level: GDP value, reserve currency/public debt to GNP, direct investment home and abroad. With regard soft power, six categories have been taken into consideration: diplomacy, socio-political, socio-economic, education, high and popular culture. All of the three researched levels were correlated with both states’ political system specificity and the character of the international arena’s relations. It allowed for the assessment of the current levels of both states’ power as well as their future prospects.

Opis:
The hard core of a theory is understood here as a set of those of its claims, which if contradicted by facts, lead to complete abandoning of the theory (in other cases scientists rather modify theoretical statements of minor importance). I argue therefore that it is an illusion that a set of statements about variation and natural selection is such a hard core of Darwinistic theory. In real practice these statements are compatible with almost all imaginable facts, therefore they have non-empirical character. They are only a camouflage for deeper and more fundamental claims, philosophical ones, and more exactly: materialistic, naturalistic and anti-religious ones. In this paper the I analyze a number of citations proving that leading evolutionists, from Darwin onwards, openly accepted this philosophical beliefs which are the true hard core of evolution.

Opis:
Jednym z najważniejszych parametrów analizy technicznej instrumentów na rynkach finansowych i towarowych oraz podstawowym wskaźnikiem interesującym inwestorów jest zmienność cen. W branży surowców mineralnych oprócz zmienności cen istotne znaczenie ma tzw. premia z tytułu składowania (convenience yield, CY), która jest ważnym parametrem modelu wartości zaktualizowanej racjonalnej wyceny towarów PVM. Obydwa parametry są kluczowymi zmiennymi wykorzystywanymi w procesie prognozy cen surowców oraz w modelach wyceny opcji rzeczowych. Niniejszy referat przedstawia próbę oszacowania historycznej zmienności cen i premii z tytułu składowania dla węgla energetycznego na podstawie danych z okresów 2000-2009 oraz 2007-2009.
One of the most important parameters of technical analysis and investor interests at financial and commodity markets is price volatility. Apart from this another indicator that pays attention of commodity market participants is convenience yield which is an important factor of present value model of rational commodity pricing, PVM relating futures and spot prices. Both parameters are the key variables used for price forecasting and real option pricing. This paper, relying upon historical data, makes an attempt of assessment of hard coal price volatility and convenience yield.
