Opis:
Current concept of interferometric missions assume that they employ formations of spacecraft. The cooperation between members of a multisatellite formation is a challenging problem. One of the main difficulties is to implement a reliable system for position control and actuation. A precise control of the position and orientation of each satellite in the array is a key factor in obtaining high quality images of distant objects. The controlling system should frequently collect data about geometry and kinematics of all array elements and use actuators to keep them as close as possible to their nominal positions. Forces that are required for actuation or array reconfiguration in space can be produced by engines of various types. In most cases chemical propulsion is used, with a drawback of limited fuel resources and a danger of polluting optical elements. In our work, we analyze dynamics of satellite formation flight, in which interaction forces result from electromagnetic fields generated by coils with current. We use simple controller equation proposed by members of MIT team to control a formation of two or three aligned satellites rotating around the array's mass center.

Opis:
This study offers a cognitive linguistic account of a few remarkably innova-tive uses of proper names to denote units of measure in utterances related to current political issues in Poland, which are delivered with ironic, sarcastic or humorous intent (such as jachiry and ziemce). The novel words, which are all nonce-formations, are minor conversions. They occur preceded by numerals and are pluralised. The coinages creatively elaborate on the morphological and semantic pattern utilised in scientific terminological eponyms (such as niutony and bubnoffy). The focus of this contribution is placed on metonymies and metaphors that motivate the form and content of the coinages.

Opis:
In the years 2014–2016 two scientific units, i.e. Faculty of Drilling, Oil and Gas, AGH UST and Oil and Gas Institute – National Research Institute cooperated on the realization of a project called Optidrilltec. A group of innovative recipes of slurries to be used for sealing wellbores in shale formations were worked out. Both fresh and hardened cement slurries should meet restrictive technological requirements, therefore this issue was in the focus of the conducted research. Laboratory experiments were performed on high-class research and control/measurement equipment, thanks to which innovative recipes of cement slurries for sealing casing in shale gas formations could be worked out. These recipes comply with standards and can be successfully used as read-made applications for sealing casing installed in shale formations.

Opis:
The Lower Paleozoic shales of SW Sweden and Eastern Pomerania (Poland) have a common history related to the depositional and tectonic evolution of the Baltic Basin. The major tectonic events are recorded, among others, as joints, which are either exposed in outcrops in SW Sweden or recognised in deep boreholes located in Pomerania. We present a comparison of the regional joint systems recognized by multiple methods in the studied region. In effect of a statistical compilation of measurements, five joint sets (named JS 1 to JS 5) were identified, traceable between Eastern Pomerania and SW Sweden. Our analysis showed a general consistency of joint set orientations, independent of their distance to the Tornquist tectonic zone passing through the study region. Three of the joint sets, JS 1 striking NNE, JS 2 striking WNW, and JS 3 striking NNW, are found to be the most frequent sets, occurring in most sites. Having more constant orientation, the JS 1 and JS 3 served as indicators of possible rotation of the tectonic block or stress field in the region. JS 1 and JS 2 are interpreted as an effect of late Carboniferous stress relaxation after Variscan collision, while JS 3 and the E–W striking JS 4 might be related to the Early Devonian Caledonian compressive stage.

Opis:
The article contains an analysis of the word formation of proper names which are used in the texts of advertisements. The analyzed examples are drawn from the texts of advertisements found on television, radio, press, the Internet etc. which were produced at the end of 20 th century and the beginning of 21 st century. The article analyses two categories of these proper names: word formations which are used in contemporary Polish language (f.e. Robuś, Marysia, Stefcia, Kasia, Jasio, Krzyś, Rozalka, Basia, Bartuś, Sabinka, Julka, Karinka, Tomek, Adaś, Goździkowa) and neologisms f.e. Zapobiegalska, Zarażalski, Kichalska, Krzywonogi, Przyklapiusz, Musztarderowie, TurboDymoMan, SuperEs, Zozolka, Łazienkowo). The analysis conducted in the article proves that both types of proper names, which are word formation derivatives, appear relatively often in the texts of advertisements. This is the case since they are easy to form (advertisements take the majority of them from usage) and can perform many functions, which advertisements willingly use for their own needs. Proper names that are word formation derivatives and just proper names serve mainly as an assessment as they connote the values appreciated both culturally and socially and the values attributed to proper names are carried on the advertised products. Proper names which are derivatives create a desired picture of advertised products more expressively than other proper names, thanks to their clear word formation structure. Moreover, they expose their commercial assets so they fully use and at the same time cocreate the system of values of consumption culture.

Opis:
The current economic crisis is having a strong impact on socio-economic processes in the development of Russian cities. The impact of the crisis is particularly strong on city territory where the activity of core industrial enterprises, military units or similar institutions has been stopped. In such cases, the situation is directly related to the functioning of military units or one industrial enterprise responsible for the formation of the city. In these cities, the socio-economic situation is unstable and is close to stressful. The average level of unemployment is growing, and the population rate is decreasing. The subject of this article is associated with the processes taking place in areas that are closed administrative-territorial formations (ZATO) of the Ministry of Defence of the Russian Federation in post-Soviet space. The closed town Zvezdniy will be presented as an example.

Opis:
We assess the suitability of luminescence (TL and OSL) dating techniques for establishing a precise Late Pleistocene chronology for the northern Baltic area, and show on the basis of the fine sand/coarse silt fraction of subaqueous deposits, how sedimentological composition influences the dates obtained. Turbidity, loading by fine suspended material, water depth, velocity of outwash streams and transport length, and also perhaps rapid night-time sedimentation and incorporation of older, unbleached particles are factors that variably influence the extent of bleaching of the luminescence signal, and thus, cause variability of dates obtained. Alongside reliable dates for "late-glacial" deposits between 11 000-15 000 OSL years BP, many entirely unreliable dates from 8 000 ±300 to 114 000 ±8 000 OSL years BP have been obtained. This means that the age determination of glaciofluvial deposits is extremely difficult in practice. This applies particularly to intermorainic sediments, the exact genesis of which is unknown. The paper is addressed to the investigators wishing to use luminescence dating techniques to establishing the Pleistocene chronostratigraphy of glaciofluvial deposits.

Opis:
Special operations forces (SOF) have a history of integrating with voluntary-based formations (VBF) overseas against a wide variety of threats. Despite the historical record, the current doctrine does not provide any applicable concepts to inform SOF-VBF integration. This study aims to fill this doctrinal gap and explores the concepts of a nation applying its SOF-VBF to its own comprehensive defence or total defence to make any territorial incursion or occupation too costly for an adversary. Using a mixture of qualitative and comparative research methodologies, based on secondary historical resistance sources, this study achieves four goals: defining the purpose behind SOF-VBF integration during resilience and resistance; establishing a seven-option SOF-VBF integration framework at the tactical, operational, and strategic levels; assessing these options based on strengths, weaknesses, opportunities, and risks of each to inform the implementation; and finally addressing overarching risks common to all options to inform broader risk mitigation measures. The result is seven integration options focused specifically on resilience and resistance to invasion and occupation. This paper will assess the strengths, weaknesses, opportunities, and risks of each. This study sets the stage for future analysis and additional research on this important topic.Special operations forces (SOF) have a history of integrating with voluntary-based formations (VBF) overseas against a wide variety of threats.

Opis:
This paper presents the attempts to calculate the pseudo-anisotropy of elastic parameters for the Silurian and Ordovician shale formations of several wells located in the Baltic basin. For this purpose, well-logging data were used, in particular data recorded with acoustic dipole tools. With the P and S waves velocities available, measured at the dipole setting in two orthogonal directions XX or YY (SFast and SSlow), the elastic ε and γ parameters were calculated. In this paper we evaluate the effect of different factors e.g., porosity, clay and kerogen content on the velocity of anisotropy shale gas formations. A geostatistical analysis of elastic and reservoir properties was carried out in order to determine the character of the variability of Silurian and Ordovician shale formations in all of the studied wells. Semivariograms for each well characterizing the variation of elastic parameters in the vertical direction were calculated.

Opis:
The study concerns the names of clothing, home furnishings, everyday objects, tools, and means of transport contained in the lexicon of the Bydgoszcz city dialect. This lexical stock includes the names of the outer garment (e.g. buks ‘trousers’), recreational clothes (badeje ‘swimming trunks’), headgear (e.g. lujmycka ‘hooligan’s cap’), footwear (e.g. kropusy ‘men’s shoes with high uppers’). Another area is the apartment; for example, the names of kitchen equipment have German origin (e.g. ausgust ‘kitchen sink’, kastrolka ‘saucepan’). This also concerns the names of three stools differing in height: the lowest one is called ryczka, a taller one is szemel, and the tallest is hoker. Texts in the Bydgoszcz city dialect also contain the names of artefacts necessary to perform everyday activities, such as cleaning (e.g. szruber ‘rice brush’) or laundry (e.g. balia ‘large wooden bath tub’). A separate place in the material culture of the inhabitants of Bydgoszcz is occupied by technological vocabulary, such as the names of tools (żaga ‘saw’) and transport (e.g. rolwaga ‘horse-drawn cart for transportation of goods’). Most of the names are Germanisms. A smaller number come from rural or folk dialects (e.g. modre ‘bleaching agent’, rydelek ‘visor of a cap’, szlory ‘old, trodden footwear’, trygiel ‘cast iron pot’). It is concluded that the city dialect is not only a museum or heritage park but also a treasury of old words.
Przedmiotem opisu są nazwy ubioru, wyposażenia mieszkania, przedmiotów codziennego użytku, narzędzi, środków transportu, jakie zawiera leksyka gwary bydgoskiej. Słownictwo to przynosi zarówno nazwy ubioru wierzchniego, np. buksy ‘spodnie’, jak i ubioru spodniego, np. badeje ‘kapielówki’, nazwy nakryć głowy, np. lujmycka ‘czapka luja’, nazwy obuwia, np. kropusy ‘męskie buty z cholewami’. Najbliższym otoczeniem człowieka bez wątpienia jest mieszkanie. Gwarowe nazwy wyposażenia kuchennego mają niemieckie źródłosłowie, por. ausgust ‘zlew kuchenny’, kastrolka ‘rondel’. Podobnie nazwy trzech stołków różniących się wysokością. Najniższy nazywany był ryczką, nieco wyższy to szemel, a najwyższy – hoker. Analizowane teksty z gwarą bydgoską przynoszą także nazwy artefaktów niezbędnych do wykonywania codziennych czynności, jak sprzątanie, np. szruber ‘szczotka ryżowa’, czy pranie, np. balia ‘duża drewniana wanna’. Osobne miejsce w obrazie kultury materialnej bydgoszczan zajmuje słownictwo związane z techniką (np. nazwy narzędzi, jak żaga ‘piła’) i transportem (nazwy pojazdów, np. rolwaga ‘wóz konny do przewożenia towarów’). Większość z opisanych nazw to germanizmy. Mniejszą grupę stanowią nazwy wywodzące się z gwar wiejskich (np. modre ‘środek wybielający’, rydelek ‘daszek czapki’, szlory ‘stare, rozdeptane obuwie’, trygiel ‘garnek żeliwny’). Gwara miejska jest nie tylko skansenem, ale i skarbnicą dawnych słów.

The police formations in various countries of the European Union are required to ensure the adoption of institutional patterns to increase the efficiency of detection and improvement of the management system. The subject of the conducted analysis described in this article are the adopted solutions, new forms of supervision of police formations in Ireland and in Poland and their assessment. The article details the provisions of the act adopted in 2015 and entitled Garda Siochana (Policing Authority and Miscellaneous Provisions) Act 2015, in terms of functioning of the collegial supervisory authority named Policing Authority. Knowing the need to confront the Irish solutions with the Polish ones, the provisions of the draft law of 8 March 2017 were also examined amending the Act on certain rights of employees of the office that supports the Ministry of Interior and Administration as well as officers and employees of offices supervised by the minister as well as certain other laws under which is to be established Internal Supervision Office of the Ministry of Interior and Administration. The author describes the creation and functions of Policing Authority and the Internal Supervision Office at the Ministry of Interior and Administration, the powers of the members and the specificity of action of the listed institutions. The article not only attempts to organize a synthetic knowledge of Policing Authority and the Internal Supervision Office of the Ministry of Interior and Administration, but also focuses attention on a comparison of tasks, relations between the authorities and the minister and the method of financing and control of their current activities. Author focuses mainly on identifying the similarities and differences in the legal solutions determining the existence of both institutions.

In this paper the preliminary evaluation of the potential of geophysical methods for the detection of geological formations of high cutting resistance and hard rock inclusions during the excavation by bucket wheel excavators (BWEs) is presented. The assessment of the geophysical methods for such applications was based on the findings obtained from the literature review, as well as on simulations and field tests. The field tests were conducted at South Field mine Kozani Greece and employed electrical, electromagnetic and GPR methods. Simulations were performed in 2D and 3D, in order to examine the response of GPR in a stratified geological structure consisting of several layers and boulders of various sizes at different depths.
W artykule przedstawiono wstępną ocenę możliwości zastosowania geofizycznych metod wykrywania formacji geologicznych o wysokiej odporności na skrawanie jak i wtrąceń nieurabialnych, podczas normalnej pracy koparek wielonaczyniowych kołowych. Ocena metod geofizycznych dla takich zastosowań została oparta na wynikach uzyskanych z przeglądu literaturowego, a także na symulacjach i testach terenowych. Testy terenowe przeprowadzono w kopalni South Field, Kozani w Grecji, gdzie przeprowadzono badania z wykorzystaniem metod elektrycznych, elektromagnetycznych i GPR.
