Authors: Berdnyk Mykhailo
Published: May 2020

The article presents the first mathematical model for calculating temperature fields of hemispherical bodies, which approximately simulates operation of the diamond-drilling bit and takes into account angular velocity of drilling operations and finite velocity of heat conduction, and which was created as a physicomathematical boundary problem for hyperbolic equation of heat conduction with the Dirichlet boundary conditions. Besides, a new integral transformation was formulated for the two-dimensional finite space, with the help of which and with the help of finite element method and Galerkin method a temperature field was found in the form of convergence series.
Simultaneous identification of the all parameters for the Lorenz chaotic system
Authors: Guda Anton , Zimoglyad Andrey
Published: May 2020

Drawbacks of the adaptive-searching methods, related with the problem of multi-parameter dynamic system identification are explored and highlighted. New approach, based on “moving regression” method is proposed. New approach is a hybrid method; it combines features of the “moving average” method, linear regression method and differential system representation. This combination allows to simultaneously determining complex dynamic system parameters, in spite of its chaotic behavior and measurement errors. New method possibilities are explored via identification process numerical simulation for the Lorenz chaotic system.

The method used in this study is by comparing the techniques that have been used by other researchers for the orbit propagation model. From the review that has been done, a beta regression technique is found to be a suitable technique.
MATHEMATICAL MODEL FOR AUTOMATIC CREATION THE SEMANTIC THESAURUS FOR THE SCIENTIFIC TEXT
Authors: Volkovskiy Oleg , Kovylin Egor
Published: May 2020

The paper deals with the issues related to the use of the algorithm of constructing the semantic model of the document for the creation the thesaurus of the scientific text terms in the natural language. The purpose of the paper is to develop an approach to create matching between elements of scientific text that do not have a direct syntactic link, but are semantically related to the one field. The relevance of the research is that the system does not use linguistic or vocabulary knowledge during its work, which makes it a universal tool for forming semantic correspondence between terms in a scientific text. Obtained results show that the semantic labels of a document have the highest number of intersections with semantic contours when they contain the largest number of semantically significant stems in their composition, which allows to make assumptions about a direct semantic connection between terms corresponding to such stems.

Authors: Selivyorstov Vadim , Selivyorstova Tatjana , Guda Anton
Published: May 2020

The analysis of scientific and technical information about the hardening features of steel castings, which lead to the formation of shrinkage defects is presented. The mechanisms of the relationship of the casting properties of alloys are shown. The analysis of factors that determine fluidity is carried out. The technological parameters of casting are determined, which lead to the formation of pores in steel castings. The mechanisms of porosity formation of endogenous and exogenous nature are considered. Siverts law is given, that describes the dependence of gas concentration on pressure. Graphs of changes in the concentration of nitrogen and hydrogen in the pressure range 1 - 4 atm are given for medium alloyed steel, open-hearth steel, cast iron. The mechanism of the influence of temperature and gas pressure on the process of gas evolution in the melt is analyzed. Technological methods for influencing the solubility of gases during the solidification of the casting are described. The microporosity model of Advanced Porosity Module, the Niyama criterion are analyzed. The need for further studies to develop a general model for the formation of shrinkage defects, which will take into account, inter alia, the dependence of the concentration of gases dissolved in the metal on pressure temperature, is noted.

Authors: Pryadko Nataliya , Havrilko Alina
Published: May 2020

The work is devoted to one of the mineral exploration field for processing - identification of disseminated function. The purpose of the work is to develop a methodology for determining the impregnation function according to the known size classes and the distribution of grains according to the content of valuable mineral in the size classes. An algorithm for determining of the impregnation distribution function by size classes is proposed. Having performed the classification of the crushed product according to size classes the content analysis of the valuable component in each size class is further analyzed, which allows determining the intergrowths distribution function in each size class. It is shown that the dependence of the impregnation distribution function on the size distribution function of the product is nonlinear.
REGRESSION MODEL OF THE CLASSIFICATION PROCESS AT JET GRINDING
Authors: Muzyka Lev , Pryadko Nataliya
Published: May 2020

The aim of the work is creating a regression model of the material classifying process in a jet grinding plant based on the experimental results. The data of various bulk material grinding in a laboratory mill and in industrial conditions were used. The main technological parameters affecting the performance of the classifier are determined. On gas-jet installations a number of dependences of changes in the volumetric flow rate of the material at the outlet of the classifier from the volumetric flow rate of the material at the inlet of the classifier and from the speed of the classifier rotor were experimentally got. The magnitude of the influence of each adopted factor and their mutual influence on the performance of the classifier with the determination coefficient R = 0.88 – 0.95 are obtained. The regression dependences make it possible to improve the control system for the classification process of jet grinding in a closed cycle.

Authors: Petersen Ole V.
Published: May 2020

About 220 minerals have been described from the Ilímaussaq alkaline complex. A list of all minerals, for which proper documentation exists, is presented with formulae and references to original publications. The Ilímaussaq alkaline complex is the type locality for 27 minerals including important rock-forming minerals such as aenigmatite, arfvedsonite, eudialyte, polylithionite, rinkite and sodalite. Nine minerals, chalcothallite, karupmøllerite-Ca, kvanefjeldite, nabesite, nacareniobsite-(Ce), naujakasite, rohaite, semenovite and sorensenite appear to be unique to the Ilímaussaq complex.
Geochemical overview of the Ilímaussaq alkaline complex, South Greenland
Authors: Bailey John C. , Gwozdz Raymond , Rose-Hansen John , Sørensen Henning
Published: May 2020

The Ilímaussaq alkaline complex is one of the latest members of the Mesoproterozoic Gardar igneous province. It was emplaced in three phases, (1) augite syenite, (2) alkali acid rocks and (3) the dominant agpaitic nepheline syenites. The immediate parent for the nepheline syenites is the augite syenite whose geochemical features, such as the low Zr/Nb ratio (3.7), match benmoreites from a nearby alkali basalt series.

The agpaitic nepheline syenites are characterised by exceptionally high contents of Zr, Hf, Nb, Ta, REE, Th, U, Sn, Li, Be, Rb, Zn, Pb, Sb, W, Mo, As and Ga, and the volatile elements F, Cl, Br, I and S but exceptionally low levels of Ba, Sr, Co, Cu, Ni, Sc, V and Cr. Fractionation of cumulus phases with a distinctive geochemistry, such as sodalite (rich in Cl, Br, I, B), eudialyte (Zr, Hf, Nb, Ta, W, As) and arfvedsonite (Co, Sc, V, Cr), caused exhaustion of these elements in the residual magmas. The agpaitic magmas underwent extreme fractionation with the final lujavrite forming after 99% crystallisation of the augite syenite. Zirconium was apparently soluble in Ilímaussaq melts up to a concentration of c. 9000 ppm. Whole-rock analyses define a number of discrete Zr–U arrays which are restricted to certain intervals of the cumulate stratigraphy and are taken as evidence for liquid layering in the Ilímaussaq magma chamber. The distribution of the less common trace elements (Bi, Cd, Co, Ge, In, I, Hg, Sc, Se, V, W) and of the more abundant trace elements which failed to form minerals (Br, Cs, Ga, Hf, Rb, Sr) is summarised.
Distribution of germanium in rocks and minerals of the Ilímaussaq alkaline complex, South Greenland
Authors: Bailey John C.
Published: May 2020

In the agpaitic nepheline syenites of the Ilímaussaq complex, analyses by X-ray fluorescence spectrometry reveal that Ge is largely held in arfvedsonite (2.4–4.3 ppm) and aegirine (2.5–4.3 ppm) and has abnormally low contents (down to < 0.2 ppm) in microcline. This distribution is discussed in relation to three controls: (1) increased ratios of octahedral to tetrahedral Ge in Na-rich, Ge-bearing melts and in high-pressure melts, (2) increased ratios of bivalent to quadrivalent Ge in highly reduced melts and (3) reduced admittance of Ge into the structurally ordered low microcline which crystallised in the low-temperature agpaitic magmas.
The distribution of minerals in hyper-agpaitic rocks in terms of symmetry: evolution of views on the number and symmetry of minerals
Authors: Khomyakov Alexander P.
Published: May 2020

Among the unique mineral localities of the Earth the complexes of nepheline syenites with hyper-agpaitic differentiates are of special interest due to their extreme diversity of mineral species. The four best studied complexes of this type – Khibina, Lovozero, Ilímaussaq and Mont Saint-Hilaire – have yielded more than 700 mineral species of which about 200 are new. The great mineral diversity is due to the combination of several factors, the most important of which is the extremely high alkalinity of agpaitic magmas, causing about half of the elements of the periodic table to be concentrated together. Minerals from hyper-agpaitic rocks are characterised by the predominance of highly ordered, low-symmetry crystal structures resulting, in particular, from the markedly extended temperature range of crystallisation. Generalisation of available data for unique mineral localities underpins the hypothesis that there is no natural limit to the number of mineral species. It is predicted that by the middle of the 21st century, the overall number of minerals recorded in nature will exceed 10 000, with the proportion of triclinic species increasing from the present 9% to 14.5%, and that of cubic species decreasing from 10% to 5%.
The hyper-agpaitic stage in the evolution of the Ilímaussaq alkaline complex, South Greenland
Authors: Sørensen Henning , Melchior Larsen Lotte
Published: May 2020

The term hyper-agpaitic covers mineral associations characterised by a wealth of Na-rich minerals such as natrosilite, zirsinalite, ussingite, vuonnemite, vitusite and lomonosovite. This mineral association clearly indicates a higher degree of alkalinity than for agpaitic rocks in general. In the Ilímaussaq complex hyper-agpaitic mineral associations occur not only in pegmatites and hydrothermal veins as in the Kola complexes, Khibina and Lovozero, but also in highly evolved lujavrites and in the fenitised volcanic rocks in the roof of the complex. This paper reviews the occurrences of hyper-agpaitic mineral associations in the Ilímaussaq complex. The mineral assemblages are determined by an interplay of temperature, pressure, oxygen fugacity, alkalinity, especially the concentration of Na, and contents of elements such as Zr, Ti, Nb, REE, Fe, Mn, U, Th, P, F, Cl and H2O. Increasing and decreasing stages of alkalinity may be distinguished. At increasing alkalinity nepheline is for instance substituted by naujakasite, while at decreasing alkalinity and temperature naujakasite is substituted by analcime.
Naujakasite from the Ilímaussaq alkaline complex, South Greenland, and the Lovozero alkaline complex, Kola Peninsula, Russia: a comparison
Authors: Khomyakov Alexander P. , Sørensen Henning , Petersen Ole V. , Bailey John C.
Published: May 2020

Naujakasite, Na6(Fe,Mn)Al4Si8O26, long known from the Ilímaussaq alkaline complex, South Greenland, was not reported until 1999 from other occurrences of alkaline rocks in spite of the fact that the mineral is composed of common elements. In 1999, a variety of naujakasite rich in Mn was found in the Lovozero alkaline complex in the Kola Peninsula, Russia. This variety has been approved by the IMA as a new mineral, manganonaujakasite, Na6(Mn0.53Fe2+ 0.47)Al4Si8O26. At Ilímaussaq naujakasite is a rock-forming mineral in the highly evolved rock naujakasite lujavrite in which it may make up more than 75 vol.%; at Lovozero manganonaujakasite is a very rare constituent in mineralised lovozerite–lomonosovite lujavrite. Naujakasite appears to take the place of nepheline in hyper-agpaitic nepheline syenites characterised by exceptionally high Na/K ratios. The nepheline syenites at Ilímaussaq have an average Na/K (atomic) ratio of 3.08, and the naujakasite lujavrites have the extreme ratio 4.56. The nepheline syenites of the Khibina and Lovozero complexes are characterised by lower Na/K ratios, 1.27 for Khibina and 1.67 for Lovozero, and thus nepheline is stable in the hyper-agpaitic rocks and naujakasite occurs only in pegmatites.
Zoning in steenstrupine-(Ce) from the Ilímaussaq alkaline complex, South Greenland: a review and discussion
Authors: Khomyakov Alexander P. , Sørensen Henning
Published: May 2020

Most crystals of steenstrupine are metamict, but some are crystalline throughout or in thin marginal zones parallel to the crystal faces of metamict crystals. The anisotropic parts of the crystals have lower contents of U and Th than the interior isotropic parts. Some features, such as high contents of Na in the anisotropic steenstrupine, favour formation of the zonation as a result of crystallisation in a medium in which decreasing amounts of U and Th were available during the last stages of growth of the crystals. One reason for this could be the fixation of U and Th in interstitial pigmentary material. Another feature, the fact that steenstrupine adjacent to fractures penetrating the crystals from the surface is anisotropic, indicates that leaching and recrystallisation may also play a role in the transformation of parts of metamict steenstrupine into an anisotropic phase.
Notes on leucophanite from the Ilímaussaq alkaline complex, South Greenland
Authors: Bohse Henning , Petersen Ole V. , Niedermayr Gerhard
Published: May 2020

Leucophanite from the Ilímaussaq alkaline complex was first described in 1905. For nearly 60 years it was believed to be rare and of very limited distribution in Ilímaussaq, but it has lately proved to be of relatively widespread occurrence. Detailed descriptions of the various occurrences are given. The crystals show the forms {001}, {110}, {101}, {102}, {111} and {113}; all the crystals are twinned either along (110) or (010). Optically the Ilímaussaq leucophanite is biaxial with 2Vα (measured) = 40°; α = 1.575, β = γ = 1.597. The empirical formula, calculated on the basis of Si + Al = 4, is: (Ca1.97Mg0.05REE0.06)Σ2.08(Na2.13K0.01)Σ2.14Be1.92(Si3.88Al0.12)Σ4.00O12.01(F1.87OH0.19)Σ2.06. Unit cell parameters determined on the newly found material are a = 7.38–7.40, b = 7.40–7.41, c = 9.96–9.95, all ± 0.01 Å (Kangerluarsuk) and a = 7.43, b = 7.43, c = 9.90, all ± 0.01 Å (Nakkaalaaq). Thus, a full set of data for the Ilímaussaq leucophanite is now available.

Authors: Türker Lemi
Published: May 2020

Some geometrical isomers of tetranitro-tetraazabicyclonanones (the titled compounds) and some of their constitutional isomers are investigated quantum chemically at the level of B3LYP/6-311++G(d,p). The constitutional isomers differ from the title compounds by the position of the carbonyl group. All the structures are nitramines (actually nitramides of organic sense). The constitutional isomers considered are capable of exhibiting proton tautomerism (keto-enol type). The tautomers have also been subjected to density functional treatment at the same level of calculation. For all the structures various electronic, energetic and spectral data have been collected and discussed.

Comparison of Bray Curtis and Nei’s Genetic Distance on Mantel Test for Chicken Diversity Data
Authors: ONDER Hasan , MERCAN Levent
Published: May 2020

In this study we aimed to examine the effects of both Nei’s genetic distance and Bray Curtis distance versus geographical distance for Mantel test on chicken diversity data. Many researchers used Nei’s genetic distance which measure that genetic differences arise due to mutations and genetic drift but some researchers used Bray Curtis distance which used to quantify the compositional dissimilarity between two different locations. We used molecular data from 28 microsatellite loci with the sample size of 364 local chicken from 45 locations and Euclidean distance of this locations using Google Earth v.4. Mantel test results suggest that relationship between genetic differentiations and geographic distance between populations using Bray Curtis distance could be substituted for Nei’s genetic distance with great reliability on chicken diversity data.

Discrete nature of relational trust networks: A multilayered model for healthcare systems
Authors: Chakraborty Somyajit , Gayen Avijit
Published: May 2020

Medical Trust-Network is one of the most promising fields of study in network science. Establishment of trust within medical entities ensures better treatment and increases better medical facilities. The word 'Trust' signifies a very important behavioral aspect between any human entities, especially among doctors and patients. To represent such relationships Trust Network Models are built to express the interactions between human entities within such networks. Though the idea of a Trust-Network has traditionally been one of the major areas of research, yet the concept of a medical trust network model is relatively a new domain. In this paper, we introduce an overall multilayered Trust Network to represent the entire healthcare architecture. More specifically our model is based on an evolutionary graph system with a discrete relationship between the three most important entities of any healthcare system, namely -- Doctors, Departments, and Hospitals. Observations indicate that based on our model, the medical healthcare system is a multilayered model unlike a feed-forward model as indicated by previous studies.

Circumstances of Poland’s Independence in Women’s Accounts. Participants and Witnesses
Authors: Załęczny Jolanta
Published: May 2020

Women have always played an important, though not always fully perceived and properly exposed, role in the history of our nation. They were active participants in many significant events, engaged in armed struggle and took part in political and social life. They supported soldiers and political activists. This has given them an important place in the public consciousness. It is hard to imagine discussing any event today without taking into account the participation of women and the female perspective on the event. This also applies to Poland’s regaining of independence in 1918. It is worth looking at these events through the prism of not only famous writers, but also other women (among others: Zofia Romanowicz, Countess Maria Lubomirska), who, by taking part or observing, recorded them as written accounts.
From the January Uprising of 1863 to Regaining Independence in 1918 – a Synthesis of Polish History in the Blue uniform [Błękitny mundur] by Donata Dominik-Stawicka
Authors: Olszewska Maria Jolanta Olszewska
Published: May 2020

The novel of Donata Dominik-Stawicka entitled The Blue uniform [Błękitny mundur] treats about Poles’ way to regaining independ­ence by Poland, starting from the January Uprising in 1863 to No­vember 1918. The way to freedom consisted of the armed struggle of Poles from various partitions, the tragic that in time World War I, fighting on different fronts under foreign command, they had to stand against each other. The title blue uniform is a reference to the biogra­phy of one of the heroes of the novel – the soldier of the Blue Army of General Józef Haller. He is, next to the gray uniform of soldiers of Józef Piłsudski, a symbol of dreams about the Polish army and the free homeland. The Blue Uniform is a family saga based on the stories of ancestors, photographs and other souvenirs. Family history on the ba­sis of pars pro toto becomes a story about a nation struggling for sur­vival, its own identity and dignity. The memory of the past of an indi­vidual and collective character passed from one generation to the next turns out to be the superior value. Intergenerational communication builds historical, cultural and community identity. The intergenera­tional relationship is ethical and the memory of the past is the same as pride. The author writes her narrative about the family and the nation into the post-memory discourse. Thanks to the testimonies of our an­cestors, history becomes an important source of identity.
“The World of Tomorrow” or “The World of Yesterday”? The Image of an Independent Nation at the 1939 New York World’s Fair
Authors: Filonik Apolonia
Published: May 2020

Poland’s presence at World’s Fairs between the World Wars is a spe­cial issue in that, after a long absence on the map of Europe, the coun­try had the opportunity to show its industrial and cultural achieve­ments in the international arena as an independent exhibitor for the first time. Thus, this event always had a very important political di­mension. Its symbol was the Polish pavilion presented in Paris in 1925, but no less important was the pavilion at the New York World’s Fair in 1939. Although it was a success at the world expo, it was overshadowed by the tragic consequences of the outbreak of World War II almost from the beginning. From today’s perspective, it is worth looking at this object, to evaluate its foundation and ultimate significance, as well as to reflect on the difficult concept of national art, in addition to trac­ing the fate of the pavilion.
Macro-prudential Policy and its Impact on the Reduction of Systemic Risk
Authors: Tuszyński Michał
Published: May 2020

The main objective of this paper is a holistic representation of the idea of macro-supervision, pointing to the need for its implementation and demonstration based on research and historical data that macro-pru­dential policy can significantly prevent the materialization of systemic risk in the banking business. This means that it will be able to coun­teract this risk in both temporal and structural terms, translating into better functioning of the real economy, which the financial system pri­marily serves. The article will present the history of the idea of macro-supervision and its concept in the light of different economic schools. Next, the characteristics of the financial system, sources of systemic risk and macro-prudential policy objectives will be shown. Attention will also be given to the other objectives of this idea. In the next stage of work, a range of policy instruments will be presented.
Anonymous in Hungary. P dictus Magister’s Gesta, Age and Pusztaszer – About the Truth of Writing History
Authors: Horváth Gábor
Published: May 2020

One of the most frequently quoted and examined topic of the historiograpy of the Hungarian Middle Ages is P dictus magister and his work, Gesta Hungarorum. Throughout the many hundred years of research, there had been several occasions when the author of the Gesta was thought to be identified. Unfortunately, he was not, as there is no consensus on his identity until this day. The starting point for almost all the experts on the topic was the same, which meant two alternatives. Firstly, that “P” was in most cases supposed to stand for the Latin “prae” preposition, and secondly, that it was the initial letter of the author’s name (eg. Petrus, Paulus, or Pósa). We can say that research was determined by these two hypotheses.

I based my research on the fact that P dictus magister was a learned, educated man of the Middle Ages, who was a scholar of literature, a key figure, whose ideas were characterised by spiritual, biblical, theological way of thinking – all of them typical of the age.

According to my conclusions, the Gesta must have been written after 1206 and before 1217, when Kalán, the bishop of Pécs, who was the author of the Gesta in my opinion, took the sign of the cross between 1214 and 1217. We can see that the Gesta reflects the crusaders’ ideals. Bishop Kalán must have had the knowledge to write the work, he must have known the places, and his service at the chancellery, as a governor, and as the bishop of Pécs made him absolutely suitable for it.
Polish Literature in Albanian
Authors: Zissi Leonard
Published: May 2020

Albania is a small country in Europe, which was under Turkish occupation for nearly five centuries. It did not regain its independence until 28 November 1912. During the occupation there was almost no foreign literature translated into Albanian, as more than 85% of the population were illiterate and in general there were no scientific institutions or schools. The first primary school was opened in 1887. Only in the 1920s, with the emergence of intelligentsia, world literature started to be translated into Albanian, which included Polish literature. However, the translations were not done from the Polish language but from Italian translations of it. The first Polish literary work translated into Albanian from Italian was the Nobel prize winner Henryk Sienkiewicz’s novel, Quo Vadis? (in 1933). The book was translated for the second time in 1999. The translation of Polish literature into  Albanian gained momentum after World War II, and especially after 2000. So far, nearly 55 books by 34 Polish authors have been translated into  Albanian, including Adam Mickiewicz (among them his great work, Pan Tadeusz), Henryk Sienkiewicz, Boleslaw Prus, Czesław Miłosz, Wisława Szymborska, Olga Tokarczuk, Ryszard Kapuściński, Tadeusz Różewicz, Witold Gombrowicz, Fr. Marcin Czermiński, and  others. At the same time, 8 Albanian authors wrote books on Polish topics in Albanian. Apart from the Albanian translators from Albania, Polish literature has also been translated into Albanian by Albanians from Kosovo. In comparison with other European countries,  Albania is a leader as far as the number of Polish books translated is concerned. Polish literature in Albanian is generally popular among Albanian readers. Some of the books are published for the second, or even after the third time.
Youth Literature on the Polish Publishing Market in 2008-2018 (Trends, Currents, Phenomena)
Authors: Rogoż Michał
Published: May 2020

In 2008-2018, the Polish market of young readers’ books was subject to various fluctuations related to economic determinants, demogra-phy and changing cultural trends or fashions. The dynamics of sales was determined by best-selling fantasy series coming mainly from the Anglo-Saxon literature. Although Harry Potter was not followed by an equally successful novel cycle, the main elements of its marketing strategy have been duplicated and continued. An important reinforce-ment of the message was the screening of a particular plot, and thus its multiplication in various media channels. Fantasy themes often re-ferring to the elements of horror, Gothic novels, and even dystopian thrillers dominated. Generic syncretism and even various formal ex-periments in the spirit of deconstruction have become characteristic of the contemporary youth book market. In contrast, the list of awards of the Polish section of the IBBY stands in opposition to this trend, which promoted, in the overwhelming majority, novels of morals na-ture, addressing difficult and controversial problems of adolescence, interpersonal relationships, otherness, etc. In this context, we can ob-serve a change in the values promoted and a transition from an edu-cative normative system to glorifying freedom and tolerance towards a wide range of behaviors and attitudes.
Dracula – nowe perspektywy badawcze
Authors: Grabias Magdalena
Published: May 2020

Dziedzina studiów gotyckich, wywodząca się z romantycznej tradycji brytyjskiej i obejmująca badania nad literaturą i filmem, staje się coraz bardziej popularna także w krajach nieanglojęzycznych. Potwierdzają to liczne publikacje analizujące elementy gotyckie w pozycjach literackich i kinie narodowym krajów takich jak Hiszpania (np. Xavier Aldana Reyes, Spanish Gothic [Hiszpański gotyk], Londyn 2017) czy Włochy (np. Rober-to Curti, Italian Gothic Horror Films, 1970-1979 [Włoskie gotyckie horro-ry filmowe, 1970-1979], Jefferson, NC 2017). Na polskim rynku wydaw-niczym w ostatnich latach również nie zabrakło publikacji poświęconych omawianej tematyce. Ukazały się m.in. pozycje takie jak: Groza w kulturze polskiej pod redakcją Roberta Dudzińskiego, Kamila Kowalczyka i Joan-ny Płoszaj (Wrocław 2016); Upiór w kamerze. Zarys kulturowej historii kina grozy autorstwa Magdaleny Kamińskiej (Poznań 2016); Anatomia strachu. Strach, lęk i ich oblicza we współczesnej kulturze pod redakcją Bogusławy Bodzioch-Bryły i Lilianny Dorak-Wojakowskiej (Kraków 2017); Oblicza wampiryzmu pod redakcją Anny Depty, Szymona Cieślińskiego i Michała Wolskiego (Wrocław 2018) i wiele innych.
Wojny wywoływane hasztagiem
Authors: Zinkow Leszek
Published: May 2020

Niespełna rok po amerykańskiej premierze na polskim rynku księgarskim pojawiła się książka, którą waszyngtońskie instytucje think tanks i prasa, zarówno specjalistyczna (od „Foreign Affairs” po „Kirkus Reviews”), jak codzienna (m.in. „New York Times”), zgodnie nazwały jedną z najlepszych i najważniejszych książek non fiction 2018 r., a wybitni eksperci – pośród nich Francis Fukuyama, gen. Michael Hayden (były dyrektor Narodowej Agencji Bezpieczeństwa USA oraz szef CIA) czy nawet Vinton Gray Cerf, uważany za jednego z wynalazców Internetu, i liczni inni komplementowali słowami najwyższego uznania. Oryginalny tytuł, brzmiący w języku angielskim bardzo celnie, a zarazem przewrotnie – LikeWar – co rozumieć można jednocześnie jako „wojnę lajków” i „nibywojnę”, przetłumaczony został bodaj nieco banalnie i mniej marketingowo: Nowy rodzaj wojny, dopiero druga jego część, podobnie do anglojęzycznej, doprecyzowuje, że chodzi o Media społecznościowe jako broń. W istocie jednak tytułowe sformułowania militarne – „wojna” oraz „broń” wskazują dobitnie na główny przedmiot analizy prowadzonej w książce, którą admirał marynarki Stanów Zjednoczonych i jeden z byłych najwyższych dowódców NATO, James G. Stavridis, zdefiniował jako najważniejszą analizę teorii konfliktu zbrojnego od czasów klasycznego Vom Kriege Carla von Clausewitza, skrojoną na miarę wyzwań XXI w.

Adaptive Safe Distance Prediction Using MPC for Bridge Cranes Considering Anti-Swing in Dynamic Environment
Authors: Chen Huili , Liu Guoliang , Tian Guohui , Zhang Jianhua , Ji Ze
Published: May 2020

In dynamic environment, the suddenly appeared

human or other moving obstacles can affect the safety of the

bridge crane. For such dangerous situation, the bridge crane

must predict potential collisions between the payload and the

obstacle, keep safe distance while the swing of the payload must

be considered in the mean time. Therefore, the safe distance is

not a constant value, which must be adaptive to the relative

speed of the bridge crane. However, as far as we know, the

mathematical model between the safe distance and the relative

speed of the bridge crane has never been fully discussed. In

this paper, we propose a safe distance prediction method using

model prediction control (MPC), which can make sure that the

crane can stop before the obstacle, and avoid possible collisions,

while the relative speed and anti-swing are both considered. The

experimental results prove the effectiveness of our idea.

Authors: Bejes Bruna Mezzomo , Pilar Camila Rodrigues , Oliveira Heleise Farias dos Reis de
Published: May 2020

O presente estudo trata-se de um relato de experiência acadêmica, vivenciada em um hospital regional, durante o estágio supervisionado do curso de bacharelado em Educação Física. A vivência no campo
hospitalar proporcionou novas experiências para as acadêmicas e pode-se comprovar se o que ocorria na prática era o que se entendia na teoria. A vivência proporcionou uma análise quanto ao papel do educador
físico dentro do ambiente hospitalar, bem como averiguar os trâmites desta área e indagar o que ainda pode ser aperfeiçoado pelo profissional em questão. O período desta prática ocorreu no ano letivo de 2019 entre
os meses de maio a novembro cumprindo uma carga horária de 7 horas semanais fechando ao todo 253 horas no ano. Ao concluir este estágio na área da saúde foi possível aprimorar o conhecimento científico e
técnico, um dos aspectos facilitadores que contribuíram para este aprimoramento foi o conhecimento das áreas de Fisiologia Humana, Fisiologia do Exercício, Bases Neuro-funcionais, Biologia Celular, Histologia e Anatomia Humana.

Altos níveis de estresse e a presença de dor, causada por sintomas osteomusculares, afetam diretamente a qualidade de vida. O Lian Gong pode ter efeito positivo na diminuição dos níveis de estresse, sintomas
osteomusculares e consequentemente melhora da qualidade de vida, além de ser uma prática corporal de baixo custo e com capacitações oferecidas no Sistema Único de Saúde, sendo assim acessível aos profissionais que queiram utilizá-lo para promoção da saúde. Assim, este trabalho teve o objetivo de identificar se há alterações nos níveis de percepção de estresse, qualidade de vida e/ou nos sintomas osteomusculares de usuários, decorrentes da prática do Lian Gong. Para isso, a pesquisa foi realizada de forma longitudinal, avaliando o nível de estresse, nível de atividade física, qualidade de vida e sintomas osteomusculares antes e após a aplicação da prática do Lian Gong, que teve duração de doze semanas, com frequência de três vezes por semana. Os resultados demonstram que os níveis de estresse foram reduzidos, a percepção da qualidade de vida melhorou, principalmente no domínio físico e os relatos de sintomas osteomusculares diminuíram, porém, somente houve significância estatística referente aos sintomas osteomusculares. Assim, só é possível afirmar, baseado neste estudo, que o Lian Gong causa alterações positivas nos sintomas osteomusculares.
