Opis:
The article presents a – to the best of the author’s knowledge – new method of preparing data for quantification of loanword adaptation, together with two of its possible uses. The method is particularly fit for poorly investigated languages where a great deal of data, especially socio-linguistic, are missing. It is illustrated with the example of Russian loanwords in Dolgan. The result is an attempt to measure the commonness and meaningfulness of adaptations, and an index of loanword nativization

Opis:
In this article, the main subject of interest is the media image of gender, which is a relatively new phenomenon in the Polish public discourse but arouses strong emotions. The content analysis included materials containing the notion of gender, published in the editorial section of “Gazeta Wyborcza” between 2010–2014. The research showed that the issue of the social and cultural aspects of gender is more and more often present in the public debate, which is strongly polarized in nature. The gathered data allowed for the enumeration of subjects which include the context connected with gender and showed the essence of presenting this subject, in a specific Polish daily newspaper, casting light on the debate in this area.

Opis:
Online quantitative analysis of reaction gases or exhaust in industrial production is of great significance to improve the production capacity and process. A novel method is developed for the online quantitative analysis of reaction gases or exhaust using quantitative mathematical models combined with the linear regression algorithm of machine learning. After accurately estimating the component gases and their contents in the reaction gases or exhaust, a ratio matrix is constructed to separate the relevant overlapping peaks. The ratio and calibration standard gases are detected, filtered, normalized, and linearly regressed with an online process mass spectrometer to correct the ratio matrices and obtain the relative sensitivity matrices. A quantitative mathematical model can be established to obtain the content of each component of the reaction gases or exhaust in real time. The maximum quantification error and relative standard deviation of the method are within 0.3% and 1%, after online quantification of the representative yeast fermenter tail gas.

Opis:
Neuroblastoma, the most common extracranial solid tumour of childhood, is a malignancy of unknown origin and non-specific symptoms. One of the markers of the disease is GD2 ganglioside (disialoganglioside), which is abundantly expressed on the surface of neuroblastoma cells. Gangliosides are known to be shed by tumour cells and this phenomenon can be significant in cancer progression as they inhibit a number of immune responses both in vitro and in vivo. In search for novel markers useful in monitoring and prognosis of neuroblastoma, we developed and validated a new quantitative method of GD2 ganglioside analysis in human blood plasma. We evaluated the level of gangliosides in blood serum of 34 neuroblastoma patients using high-performance liquid chromatography. The technique was used to detect fluorescently labelled oligosaccharides derived from serum glycosphingolipids by enzymatic digestion with ceramide glycanase. The developed method allowed determination of GD2 concentrations at the picomole level and required only 40 µl of plasma, which should be particularly useful when the quantity of clinical material is limiting. Moreover, this method can be applied to study concentration of other gangliosides, as shown for GD3 ganglioside. Analysis of plasma samples from the 34 neuroblastoma patients did not reveal any correlations between the concentration of GD2 ganglioside and clinical parameters, including the results of therapy; it showed, however, that the concentration of GD2 ganglioside in the plasma of neuroblastoma patients decreased substantially in the course of treatment.

Opis:
The aim of the study was to examine the possibility of determination and optimization of methodology for analysis of three selected drugs: trimethoprim, sulfamethoxazole and diclofenac in urine using high-performance liquid chromatography, without extraction of the pharmaceuticals to the solid phase. The chromatographic separation conditions were determined using a gradient elution system and mobile phase, which was a mixture of acetonitrile and a phosphate buffer, allowing detection of trimethoprim, sulfamethoxazole and diclofenac from 260, 210 and 310 μg/L respectively, and simultaneous determination of these analytes in the presence of urine components.
Celem pracy było sprawdzenie możliwości i opracowanie metodyki oznaczania trzech wybranych leków: trimetoprimu, sulfametoksazolu i diklofenaku w moczu z wykorzystaniem wysokosprawnej chromatografii cieczowej (ang. high performance liquid chromatography, HPLC) bez uprzedniej ekstrakcji analitów do fazy stałej. Określono warunki rozdzielania chromatograficznego z zastosowaniem elucji gradientowej fazy ruchomej, którą była mieszanina acetonitrylu i buforu fosforanowego, co pozwoliło na detekcję trimetoprimu, sulfametoksazolu i diklofenaku odpowiednio na poziomie od 260, 210 i 310 μg/l i równoczesne oznaczenie tych analitów w obecności składników moczu.

Opis:
In this summary, it is essential to highlight that in his statements, J. Kaczyński touches upon a narrow range of subjects. He uses merely 12 nouns on a regular basis (issue, politics, Poland, Prime Minister, democracy, law, society, country, opposition, truth, economy (or finance) and prices). He rarely addresses foreign policy issues and fails to specifically refer to historical facts. However, it is impossible not to notice his critical assessment of the Polish government's actions. The most prominent subject of Kaczyński's speeches are the current state of democracy in Poland. This sentiment is best captured by the quotation “it is a practice [here: about the actions of the Polish Sejm - author's note] which does not fit into the framework of democracy”. This tone is used to refer to the alleged breaching of opposition's law, which points out the terrible condition of Polish democracy. Kaczyński's speeches paint the picture that the basic provisions of democracy being broken. Among his claims are alleged lying to the society by those in power, lack of control mechanisms over the institutions guiding the country's actions, inequalities in Polish political procedure, and, most importantly the breaking of the laws of the opposition.

Obwohl nach Marx/Weidacher (2014:91ff.) von keiner Internet-Sprache die Rede sein kann, ist leider die in Diskussionen und Kommentaren auf Facebook, Twitter oder Weblogs genutzte Sprache, oft gefüllt von beleidigenden, hassvollen Wörtern und Ausdrücken. Genau diese Art von Sprache wird als Hasssprache (auch Hassrede) genannt. Im folgenden Beitrag wird die Hasssprache am Beispiel von deutschen, dänischen und polnischen Facebook-Kommentaren zum Terroranschlag in Manchester (Mai 2017) analysiert. Es wurde eine qualitative Analyse durchgeführt, indem die Stellungnahmen in Bezug auf die dort vorkommenden Wörter und Wendungen, die in allen drei genannten Sprachen als beleidigend betrachtet werden, untersucht werden. Ich versuche dabei, folgende Fragen zu beantworten: Welche sprachlichen Mittel sind für die Kommentare charakteristisch? Sind irgendwelche von diesen Mitteln speziell bevorzugt? Welches Ziel möchten die Kommentierenden erreichen? Welche Inhaltsunterschiede lassen sich zwischen deutschen, dänischen und polnischen Kommentaren feststellen? Welche Aspekte des Inhalts berühren sie?

I try to find answer on following questions: Which linguistic methods are characteristic for such comments? Are some of these methods preferred? What are the authors of such comments trying to achieve? What are the differences between German, Danish and Polish comments? Which aspects of content do they touch?

Opis:
The paper aims at recognizing the possibilities and perspectives of application of qualitativequantitative research methodology in the field of economics, with a special focus on production engineering management processes. The main goal of the research is to define the methods that would extend the research apparatus of economists and managers by tools that allow the inclusion of qualitative determinants into quantitative analysis. Such approach is justified by qualitative character of many determinants of economic occurrences. At the same time quantitative approach seems to be predominant in production engineering management, although methods of transposition of qualitative decision criteria can be found in literature. Nevertheless, international economics and management could profit from a mixed methodology, incorporating both types of determinants into joint decision-making models. The research methodology consists of literature review and own analysis of applicability of mixed qualitative-quantitative methods for managerial decision-making. The expected outcome of the research is to find which methods should be applied to include qualitativequantitative analysis into multicriteria decision-making models in the fields of economics, with a special regard to production engineering management.

Opis:
Morphometric attributes of 705 stromatoporoid specimens from a number of exposures from the Silurian of Podolia (Ukraine) and the Devonian of the Holy Cross Mountains (Poland), representing a wide array of shallow water carbonate sedimentary environments, have been analysed. Taken into account were such parameters as: general shape of the skeleton, shape of the final growth form (living surface profile), upper surface character, latilaminae arrangement, burial ratio and type of initial surface. A number of new ratios has been introduced, designed mainly to improve the mapping of the outlines of the stromatoporoids upper surfaces. All studied specimens were treated as belonging to one group, and relations between particular attributes were tested. The results were analysed in terms of potential environmental factors influencing stromatoporoid morphometric features. Most of the distinguished attributes are common in the studied group and occur in various combinations, with an important exception of parameters designed to reflect the shape of the skeleton’s upper surface, which are distinctly predominated by convex variants. This indicates that surface concavity was a highly undesired feature among stromatoporoids. Upper surface convexity is interpreted herein as a response to the hazard of clogging of the animals pores by tiny sediment particles suspended in the bottom turbid water layer. Common low burial ratios of final living surface profiles and the occurrence of specimens with a smooth upper surface but a non-enveloping latilaminae arrangement are other reflections of this phenomenon. Burial by sediments and redeposition were also important factors governing stromatoporoid development. No direct arguments indicating photosensitivity of stromatoporoids can be deduced from the presented results. The hitherto postulated allometric tendency among stromatoporoids of starting growth as laminar forms and later adopting consecutively higher profile shapes has not been confirmed here. On the contrary, a tendency for gradual elimination of very high profile forms with increasing stromatoporoid size has been observed. The final shape of a stromatoporoid skeleton was always an effect of a combination of various agents.

Opis:
The aim of this paper is to present a possibility to use information technology in the form of databases for processing and analyzing large image sets based on methods of image analysis and mathematical morphology. Up to now the use of databases in the image analysis process has been reduced to storing large amounts of data in the form of images. However, all transformations and analyses of such sets are made on user’s computers. This requires a large data set (images) to be sent by network each time, and also it may possess the problems resulting from managing such large amounts of analyzed photographs on a computer. The proposed approach completely eliminates these problems by moving all transformations of image analysis to a database platform. For this purpose a set of routines realizing transformations of the image analysis and mathematical morphology was developed. The proposed approach allows the unification of the image processing and analysis area and advanced statistical analyses of obtained parameters describing geometrical sizes of objects on photographs. The proposed methodology was illustrated by practical realization of two measurement types for a simple structure of copper concentrate and more complicated, from the point of view of image analysis, structures such as dolomites from Redziny and Laskowa Gora and sandstones from Tumlin and Wisniowka.

W 2006 r. z inicjatywy sześciu gmin powiatu miechowskiego powstało Miechowskie Stowarzyszenie Gmin „Jaksa”, które skupia przedstawicieli trzech sektorów: społecznego, gospodarczego i publicznego. Obecnie tworzą je: 96 członków (osoby fizyczne) i 7 samorządów gminnych, starostwo powiatowe w Miechowie oraz trzy organizacje pozarządowe. Działalność skupia się przede wszystkim na rozwoju obszarów wiejskich. W ramach działalności statutowej stowarzyszenia została opracowana Lokalna Strategia Rozwoju (LSR). W latach 2009-2015 Lokalna Grupa Działania (LGD) przy Miechowskim Stowarzyszeniu Gmin „Jaksa” realizowała projekty zawarte w priorytetach Lokalnej Strategii Rozwoju, mianowicie: „Wartość dodana do życia na wsi”, czyli wzrost poziomu i jakości życia, a także aktywizacja i integracja mieszkańców oraz „Poprawa atrakcyjności turystycznej i promocja produktu lokalnego”, w tym rozwój turystyki, zachowanie lokalnego dziedzictwa kulturowego i historycznego. To główne kierunki działań Stowarzyszenia powołanego po to, aby w oparciu o środki unijne zaktywizować społeczność lokalną do budowania infrastruktury i wspólnego działania na rzecz rozwoju obszaru. W latach 2007-2015 na realizację zadań na terenie powiatu miechowskiego przeznaczono ok. 7,5 mln zł. Były to zadania, takie jak: „Małe projekty”, „Odnowa i rozwój wsi”, „Tworzenie i rozwój mikroprzedsiębiorstw” i „Różnicowanie w kierunku działalności nierolniczej”. Celem artykułu jest: -  określenie efektów działań i operacji realizowanych w ramach poszczególnych przedsięwzięć zgodnych z Lokalną Strategią Rozwoju, -  analiza liczby projektów realizowanych w ramach każdego z przedsięwzięć wraz z oceną, które są najlepiej oraz najgorzej realizowane, - przedstawienie struktury grup beneficjentów wnioskujących o wsparcie.
In 2006, upon the initiative of six municipalities of the Miechow district, Miechow Association of Municipalities “Jaksa” was founded. It brings together representatives of three sectors: social, economic and public life sector. It has currently 96 members (individuals) and seven local governments, county authorities in Miechow, and three non-governmental organizations. Its main activity focuses on rural development. As part of statutory activities, the association developed Local Development Strategy. In the years 2009-2015, Miechow Association of Municipalities “Jaksa” Local Action Group implemented projects which included the priorities of the Local Development Strategy, namely: “Added Value” to rural life - that is, an increase of the level and quality of life, as well as the activation and integration of citizens, and “Improvement of tourist attractiveness and promotion of local products” which includes development of tourism and preservation of the local cultural and historical heritage. These are the main ways of the Association, established on the basis of EU funds, in order to activate local community to build infrastructure and join actions for the development of local area. In the years 2007-2015, for the implementation of tasks in the Miechow district, about 7.5 million PLN has been allocated. Tasks carried out in the framework of the program included: diversification, creation and development of micro-enterprises, “Village renewal” and “Small Projects”. The purposes of this article are: -  identification of effects of actions and operations carried out within the framework of individual projects consistent with the Local Development Strategy, -  analysis of the number of projects under each of ventures together with an evaluation of which projects are the best and the worst implemented, -  presentation of the structure of beneficiary groups that request support.

Opis:
Pre-processing provides an effective way for fly ash's high value-added utilization. However, the shortcomings of pre-processing methods such as grinding and flotation are apparent with many disadvantages that make it more challenging to use efficiently. Microwave heating helps the SiO2-Al.2O3 bond break, not only can make the structural change of the material can also promote the chemical reaction process. In the article, XRD, SEM, FT-IR, ammonia nitrogen adsorption, and other methods were used to analyze the changes in the properties of fly ash before and after microwave pre-treatment, the change in adsorption performance of fly ash before and after microwave treatment was analyzed. The study found that under microwave conditions of 600 W and 15 min, the adsorption rate of ammonia nitrogen by fly ash reached a maximum of 29.67%. The intensity of mullite and amorphous diffraction peaks decreased after 20 min at 600 W. The Si-O-(Si, Al) and Si-O-(Si) bonds showed significant changes at 15 min and 20 min under 600 W conditions. Based on the results, the microwave conditions were selected at 600 W for different periods, and semi-quantitative analysis was carried out by XRD-Rietveld, infrared peak fitting, and nuclear magnetic resonance. The XRD-Rietveld analysis showed that the amorphous phase content reached 46.18% at 15 min. In the infrared peak fitting, the fitting area at 1300-900 cm-1 and 600-400 cm-1 peaks at 56.92% at 25 min and 17.5% at 15 min, respectively. The silicon-oxygen network's degree of connection and polymerization was reduced after 15 min of microwave treatment for the nuclear magnetic resonance analysis. By combining specific surface area measurements, it was discovered that the maximum specific surface area attained a value of 3.122 m2/g at 15 min.

Opis:
Morphometric attributes of 705 stromatoporoid specimens from a number of exposures from the Silurian of Podolia (Ukraine) and the Devonian of the Holy Cross Mountains (Poland), representing a wide array of shallow water carbonate sedimentary environments, have been analysed. Taken into account were such parameters as: general shape of the skeleton, shape of the final growth form (living surface profile), upper surface character, latilaminae arrangement, burial ratio and type of initial surface. A number of new ratios has been introduced, designed mainly to improve the mapping of the outlines of the stromatoporoids upper surfaces. All studied specimens were treated as belonging to one group, and relations between particular attributes were tested. The results were analysed in terms of potential environmental factors influencing stromatoporoid morphometric features. Most of the distinguished attributes are common in the studied group and occur in various combinations, with an important exception of parameters designed to reflect the shape of the skeleton’s upper surface, which are distinctly predominated by convex variants. This indicates that surface concavity was a highly undesired feature among stromatoporoids. Upper surface convexity is interpreted herein as a response to the hazard of clogging of the animals pores by tiny sediment particles suspended in the bottom turbid water layer. Common low burial ratios of final living surface profiles and the occurrence of specimens with a smooth upper surface but a non-enveloping latilaminae arrangement are other reflections of this phenomenon. Burial by sediments and redeposition were also important factors governing stromatoporoid development. No direct arguments indicating photosensitivity of stromatoporoids can be deduced from the presented results. The hitherto postulated allometric tendency among stromatoporoids of starting growth as laminar forms and later adopting consecutively higher profile shapes has not been confirmed here. On the contrary, a tendency for gradual elimination of very high profile forms with increasing stromatoporoid size has been observed. The final shape of a stromatoporoid skeleton was always an effect of a combination of various agents.

Opis:
A quantitative risk analysis (QRA) should provide a comprehensive, informative and balanced picture of risk, in order to support decisions. To achieve this, a proper treatment of uncertainty is a prerequisite. Most approaches to treatment of uncertainty in QRA seem to be based on the thinking that uncertainty relates to the calculated probabilities and expected values. This causes difficulties when it comes to communicating what the analysis results mean, and could easily lead to weakened conclusions if large uncertainties are involved. An alternative approach is to hold uncertainty as a main component of risk, and regard probabilities as epistemic-based expressions of uncertainty. In the paper the latter view is taken, and we describe what should be the main pillars of a risk description following this approach. We also indicate how this approach should relate to decision-making. An important issue addressed is how to communicate the shortcomings and limitations of probabilities and expected values. Sensitivity analysis plays a key role in this regard. An example is included to illustrate ideas and findings.

This paper presents a qualitative and quantitative chromatographic analysis (GC/MS) of the lipophilic fraction extracted from leaves, inflorescences and rhizomes of Silphium perfoliatum L. collected in 1998-2000. It was shown that the extracts of leaves and inflorescences are similar in composition, containing among their main constituents: α-amyrine (up to 13.9% of total components in leaves, up to 11.3% in inflorescences), heptacosane (up to 7.1% in leaves, up to 7.6% in inflorescences), stigmasterol (up to 8.1% in leaves, up to 2.2% in inflorescences), γ-sitosterol (up to 6.9% in leaves, up to 2.2% in inflorescences), β-amyrine (up to 4.1% in leaves, up to 5.8% in inflorescences), β-caryophyllene (up to 2.6% in leaves, up to 1.5% in inflorescences), caryophyllene oxide (up to 4.4% in leaves, up to 2.9% in inflorescences), germacrene D (up to 13.8% in leaves, up to 9.7% in inflorescences) and α-pinene (up to 3.3% in leaves, up to 2.4% in inflorescences). The chemical composition of lipophilic extract of rhizomes significantly differs from that of leaves and inflorescences. The following compounds can be counted among the dominant ones occurring in rhizome extracts: diterpene of labdane type - 16-acetoxycarterochaetol (up to 45%) and sesquiterpenes - 7-b-H-silphiperfol-5-ene (up to 9.1%), 7-a-H-silphiperfol-5-ene (up to 10.7%), d-elemene (up to 7.6%), isocomene (up to 5.6%), germacrene D (up to 5.2%) and modhephene (up to 5.1%).

W artykule przedstawiono wyniki badań wpływu warunków wytapiania i odlewania eksperymentalnych stali zawierających 3÷5% glinu na rodzaj i morfologię wtrąceń niemetalicznych. Wytopy badawcze wykonano w elektrycznym piecu indukcyjnym z zastosowaniem próżni oraz w atmosferze powietrza. Przeprowadzono analizę ilościową i jakościową wtrąceń niemetalicznych po przeróbce plastycznej na gorąco. W stalach wytapianych i odlewanych w powietrzu występują głównie wtrącenia AlN, MnS, Al2O3 oraz złożone wtrącenia tlenkowo-siarczkowe. Udział objętościowy wszystkich wtrąceń niemetalicznych stanowi 0,10÷0,12% obj. i jest większy o ok. 30% w porównaniu ze stalą wytapianą w próżni.
The paper presents the effect of melting and casting conditions of experimental steels with 3÷5% of aluminium on the type and morphology of non-metallic inclusions. The experimental heats were carried out in an electric induction furnace in vacuum and in air atmosphere. A quantitative and qualitative analysis of non-metallic inclusions was conducted after hot plastic working. Steels which were melted and casted in air atmosphere contain mainly AlN, MnS, Al2O3 and complex oxide-sulfide inclusions. The volume fraction of non-metallic inclusions was 0.10÷0.12% and it was about 30% higher than the volume of inclusions in the steel produced in vacuum.

Opis:
The article contributes to a better understanding of the role of research in the policies of the states that are scientifically engaged in the High North. The research covers 17 European states: six are Arctic and 11 non-Arctic, which were selected according to the follow- ing (at least one) formulated criteria: having an established tradition of carrying out scientific research in the Arctic region; having issued Arctic policy documents and/or Arctic research strategies; participation in the activities of the Arctic Council; and having gained member- ship of the International Arctic Science Committee (IASC). In the analysis we have applied a mixed research method, since it incorporates elements of both qualitative and quantitative approaches and offers a more comprehensive review of the scrutinised texts. The qualitative analysis relies on a discourse analysis (predicate analysis). The quantitative part of the analysis utilizes the instruments of a software research tool — The AntConc. In the end, the outcomes of both methods are merged and compared. The study reveals that conducting scientific re- search is not a top priority for all Arctic states. However, it has the highest similarity in terms of applied approaches among Arctic states as compared to other fields (e.g. the economy, se- curity or pollution). At the same time, the environment and climate change are perceived to be the most important drivers behind Arctic research as defined in the Arctic states’ strategies. Moreover, there are major differences among both Arctic and non-Arctic states in terms of the level of accuracy in the presentation of their research activities, particularly with regard to the implementation of scientific programmes and research aims. Finally, the research indicates that all states highlight that international scientific cooperation stimulates cooperation also in other areas and that research provides information that supports decision making and policy creation

Opis:
The prevalence of lifestyle diseases and trends related to healthy eating contribute to the constant search for chemical compounds with specific biological activity. Studies are conducted on plants and substances of natural origin that have been used in medicine for millennia. Techniques of vibrational spectroscopy are an underrated group of methods enabling direct analysis of plant raw material and food in their native forms. The presented examples of Arabidopsis tissues, various species and hybrids of poplar and Cistus herb classification, as well as quantitative analyses of active compounds in plant material and pharmaceutical products and determination of physicochemical parameters of common food (i.e. milk, yoghurts, pasta and flour), demonstrate the possibility of using vibrational spectroscopy for comprehensive analysis of samples of natural origin. Typical measurement techniques and chemometric methods are briefly described in this paper. The scheme of quantitative analysis based on vibrational spectra is shown and the impact of selected experimental parameters on the accuracy of the obtained results is discussed. The imaging techniques used to analyse the changes in plant tissue structures caused by genetic mutations were also presented.

Opis:
Operation of storm water systems in urbanized catchments, affected by increased size of drainaged area and its relative surface sealing, significant variability of rainfall events and increased usage of transport vehicles is connected to changes of sewage flow, pollutants concentrations and loads entering the sewage receiver. Thus, the application of numerical modeling to multi-variant analyses of storm water systems operation and its influence on the natural environment is reasonable and becomes a standard procedure nowadays. This paper presents the numerical modeling application to quantitative and qualitative analysis of storm-water sewer system in conditions of the selected urbanized area in the town of population reaching 40 000. The US EPA’s (United States Environmental Protection Agency) software SWMM 5 was applied to our studies. Three different rainfall events of various time and intensity were applied to our research. The presented analysis was based on sewage flow velocity, wastewater table height in the pipelines and the load of pollutants leaving the sewerage system. The sewage flooding from several chambers was observed. Our studies reveals also the fact that the studied system is partially undersized and the observed concentration of TSS entering the receiver exceeds the maximum value allowable by the local standards. According to the lacking model calibration, our observations should be treated as the preliminary studies.
Funkcjonowanie miejskich systemów kanalizacji deszczowej, na które wpływa wzrost powierzchni odwadnianej, zmienność opadów, zmiana stopnia uszczelnienia odwadnianych powierzchni oraz wzrost wykorzystywania transportu kołowego, związane jest z ciągłymi zmianami w przepływie ścieków, a także stężeniach i ładunkach zanieczyszczeń trafiających do odbiornika. Dlatego też standardem staje się wykorzystywanie modelowania numerycznego w wielowariantowej analizie warunków pracy oraz oddziaływania na środowisko kanalizacji deszczowej. W pracy przedstawiono próbę zastosowania modelowania numerycznego do ilościowej i jakościowej analizy warunków pracy kanalizacji deszczowej dla miejskiej jednostki osadniczej o liczbie mieszkańców wynoszącej 40 000 osób. Model sieci kanalizacji deszczowej rozpatrywanego miasta wykonano w programie SWMM5 opracowanym przez USEPA (United States Environmental Protection Agency). W badaniach modelowych wykorzystano trzy opady atmosferyczne charakteryzujące się różną intensywnością oraz czasem trwania opadu. Przedstawiona analiza została oparta na prędkościach przepływu ścieków, możliwości wypływu podpiętrzonych w studzienkach ścieków na powierzchnie terenu oraz ładunkach transportowanych zanieczyszczeń. Przeprowadzone badania wykazały możliwość wypływu ścieków ze studzienek połączeniowych lub rewizyjnych na powierzchnię odwadnianego terenu wynikające z częściowego niedowymiarowania badanego układu kanalizacyjnego. Odnotowano także przekroczenie aktualnych wartości dopuszczalnych stężenia zawiesiny ogólnej we wszystkich analizowanych wariantach obliczeń symulacyjnych. Ze względu na brak kalibracji modelu otrzymane wyniki należy traktować jako wyniki badań wstępnych.

Opis:
The objective of the research was a survey identification of the presence of the history of Communist Poland, PRL, in museum narrative in 1989–2017. Importantly, this is a repeated, supplemented, and more thorough research versus the one presented in the paper ‘PRL in Museum Narrative over the Last 25 Years’ published in 2014 in the Światowid. Rocznik Muzeum PRL-u (w organizacji) periodical. The research discussed in the present paper forms part of a doctoral dissertation, constituting the research’s second stage. As a result of the conducted research based on survey answers provided by museums and on individual research a database containing 642 exhibitions was created. When processing the data, quantitative analysis was adopted. After data cleaning the following statistical trends were analysed: exhibition duration over the whole research period, percentage of leading themes, percentage of themes in respective cities. The conducted analysis has permitted to observe trends in museum narrative concerning PRL. Also the most popular exhibition duration over the research period has been identified (up to two years and permanent exhibitions). The most popular categories have been named: art history, political history, history of everyday life. Three groups of urban centres where museum narrative is present to a varied degree have been named. The fourth group contains cities in whose museums the topic of PRL has not been tackled over the last 28 years, or such projects cannot be reliably confirmed.

Własności mechaniczne staliwa są funkcją przede wszystkim składu chemicznego i warunków krzepnięcia czyli struktury pierwotnej, jednak znaczącą rolę odgrywa także jego jakość rozumiana jako czystość metalurgiczna czyli jak najmniejsza zawartość szkodliwych składników struktury. W artykule przedstawiono wyniki analizy ilościowej porowatości i wtrąceń niemetalicznych w strukturze staliwa. Do histogramów rozkładu zanieczyszczeń dopasowano statystycznie funkcję, której współczynniki można traktować jako parametry niepożądanych składników struktury. Przeanalizowano wpływ zawartości O, N, P i S na wartości współczynników funkcji aproksymującej.
The mechanical properties of cast steel are primarily a function of chemical composition and solidification conditions i.e. primary structure, however, a significant role also plays its quality understood as purity metallurgical i.e. as small as possible content of harmful components of the structure. In work the results of porosity and non-metallic inclusions in steel cast structure quantity analysis are presented. A function which coefficient can be treated as parameters of unwonted structure component was statistically fitted to histograms of impurities distribution. The influence of O, N, P and S content on approximation function coefficients was analyzed.

Analiza półilościowa składu mineralogicznego skał przy pomocy przenośnego spektrometru FT-IR jest metodą szybką i może stanowić ciekawą alternatywę dla innych metod analitycznych, takich jak XRD i XRF. Modele stworzone za pomocą algorytmu Beera będące podstawą do opracowania metodyki do analizy półilościowej dają bardzo dobre rezultaty, charakteryzując się wysokim współczynnikiem determinacji R2 dla widm podczerwonych oraz metod XRD i XRF. Przenośny spektrometr FT-IR może być z powodzeniem użyty zarówno w pomiarach laboratoryjnych, jak i terenowych. Metoda FT-IR może umożliwić szybką ocenę litologiczną przewiercanych warstw oraz jest pomocna przy wyborze prób do dalszych badań laboratoryjnych. W niniejszym artykule przedstawiono wstępne wyniki analizy półilościowej składu mineralogicznego skał zbiornikowych opartej na korelacji widm FTIR z wynikami analiz XRF i XRD.
Semi-quantitative analysis of mineralogical composition of reservoir rocks with the use of portable FT-IR spectrometer is a quick analytical method and might be an interesting alternative to other methods such as XRD and XRF. Models created using Beer’s algorithm being the basis of methodology for semi-quantitative analysis, have given very good results with a high R2 determination coefficient, for infrared spectra and methods such as XRD and XRF. Portable FT-IR spectrometer can be successfully used for laboratory analyses as well as field measurements. The opportunity to analyze the mineralogical composition of rocks allows for quick lithological assessment of drilled layers and helps during sampling for further laboratory testing. This article shows preliminary results of semi-quantitative analyses of mineralogical composition of reservoir rocks based on correlations of infrared spectra with XRF and XRD results.

Opis:
The paper presents the results of research into the pigment composition of seawater samples taken from various depths in the Gulf of Gdańsk in April and September 1999. Pigments were separated by RP–HPLC, and identification was confirmed by co-injection with reference standards and on-line diode array spectra. The following groups of pigments were identified: chlorophylls: a, b, c1 + c2; photosynthetic carotenoids (PSC) – peridinin, fucoxanthin, α-carotene; photoprotecting carotenoids (PPC) – diadinoxanthin, alloxanthin, zeaxanthin, lutein, neoxanthin, violaxanthin and β-carotene. Quantitative and qualitative diversity in pigment characteristics were observed in both seasons, though lutein and α-carotene were not identified in the September samples. The respective April and September concentrations of the functional groups of pigments were: total chlorophylls content 0.47–104.25 and 0.57–13.66 μg dm−3; PSC 0.07–21.23 and 0.02–1.56 μg dm−3; PPC 0.05–14.08 and 0.04–1.79 μg dm−3. Within the PSC group, peridinin and fucoxanthin were dominant in the April samples, but only fucoxanthin in the September ones. Among the PPCs, diadinoxanthin and alloxanthin were dominant in April, zeaxanthin in September. Photosynthetic and photoprotecting carotenoids display a linear correlation with chlorophyll a content in all the samples.

Opis:
The IN713C is nickel-based superalloy, used to produce low pressure turbine blades in a process of investment casting. However, porosity which is formed during the casting, decreases mechanical properties of IN713C. Therefore, to eliminate porosity, a process of hot isostatic pressing was applied. Nonetheless, HIP also least to some changes in the microstructure of tested material. The main aim of this paper is to characterize the morphology of carbides before and after hot isostatic pressing. Microstructural characterization was carried out with the use of a scanning electron microscope equipped with an energy dispersive X-ray spectrometer and an electron backscatter diffraction detector. The size and shape of carbides were evaluated by quantitative metallography methods methods. The results show that the amount, size and heterogeneity of arrangement of the carbides increased after application of HIP treatment.

Opis:
Morphometric attributes of 705 stromatoporoid specimens from a number of exposures from the Silurian of Podolia (Ukraine) and the Devonian of the Holy Cross Mountains (Poland), representing a wide array of shallow water carbonate sedimentary environments, have been analysed. Taken into account were such parameters as: general shape of the skeleton, shape of the final growth form (living surface profile), upper surface character, latilaminae arrangement, burial ratio and type of initial surface. A number of new ratios has been introduced, designed mainly to improve the mapping of the outlines of the stromatoporoids upper surfaces. All studied specimens were treated as belonging to one group, and relations between particular attributes were tested. The results were analysed in terms of potential environmental factors influencing stromatoporoid morphometric features. Most of the distinguished attributes are common in the studied group and occur in various combinations, with an important exception of parameters designed to reflect the shape of the skeleton’s upper surface, which are distinctly predominated by convex variants. This indicates that surface concavity was a highly undesired feature among stromatoporoids. Upper surface convexity is interpreted herein as a response to the hazard of clogging of the animals pores by tiny sediment particles suspended in the bottom turbid water layer. Common low burial ratios of final living surface profiles and the occurrence of specimens with a smooth upper surface but a non-enveloping latilaminae arrangement are other reflections of this phenomenon. Burial by sediments and redeposition were also important factors governing stromatoporoid development. No direct arguments indicating photosensitivity of stromatoporoids can be deduced from the presented results. The hitherto postulated allometric tendency among stromatoporoids of starting growth as laminar forms and later adopting consecutively higher profile shapes has not been confirmed here. On the contrary, a tendency for gradual elimination of very high profile forms with increasing stromatoporoid size has been observed. The final shape of a stromatoporoid skeleton was always an effect of a combination of various agents.

Opis:
Henryk Sienkiewicz’s novel "Quo Vadis" made its way into Italy at the end of the 19 th century through the efforts of Neapolitan translator Federigo Verdinois. The first part of this paper outlines the history of the popularity of "Quo Vadis" by focusing on the operations of Milanese publishers that made the Polish novel part of their offer in a variety of ways (as translations, adaptations, reworkings, plagiarisms, etc.). Bibliometric methods are used to establish why so many publishing houses decided to publish Henryk Sienkiewicz’s Roman romance. The analysis of the bibliometric data of the published translations helped assess and describe the extent and the character of the popularity that the novel garnered among Milanese publishers. The second part of the paper relates the findings of a multi-method quantitative study of the same material. The number of word tokens was compared between the original and the translations. The lexical richness across the texts under study was compared by means of the moving average type-token ratio (MATTR). Sentence lengths were also compared, as was sentence length distribution as time series. Two different programmes ("WCopyFind and Tracer") yielded very similar results on the degree of the similarity of five-word phrases in pairs of translations, which was determined in network analysis.
L’opera "Quo vadis" di Henryk Sienkiewicz arrivò in Italia alla fine del XIX secolo grazie al traduttore napoletano Federigo Verdinois. Lo scopo della prima parte del contributo è quello di presentare la storia della popolarità del romanzo "Quo vadis" attraverso le azioni delle case editrici milanesi, le quali hanno introdotto l’opera del polacco, in varie forme, nella sua offerta editoriale (come traduzioni, adattamenti, parafrasi, plagi). La ricostruzione della storia delle traduzioni del romanzo romano di Henryk Sienkiewicz è stata possibile grazie al metodo biblometrico che è stato ustato nella prima parte dell’articolo. L’analisi dei dati bibliografici raccolti ha permesso di valutare e descrivere la grandezza e il carattere della popolarità di "Quo vadis" tra gli editori milanesi nella prima parte del XX secolo. Nella seconda parte del contributo per meglio far luce sulle complicate sorti milanesi dell’opera di Sienkiewicz abbiamo usato alcuni metodi d’analisi quantitativa. Abbiamo paragonato il numero delle parole in originale e nelle traduzioni descritte nella prima parte. La ricchezza del vocabolario di tutti i testi esaminati è stata misurata e confrontata usando il calcolo della media mobile del rapporto del numero di parole alla lunghezza del testo (MATTR). Abbiamo confrontato anche le lunghezze delle frasi come serie temporali. I due programmi diversi ("WCopyFind e Tracer"), utili per le analisi delle reti, hanno dato risultati simili per il numero delle somiglianze delle frasi di pentagrammi verbali tra le traduzioni di "Quo vadis".

Opis:
The paper presents results of studies on the inheritance of plant height in four short-stem genotypes of rye selected from genotypically different collection materials. Short-stem genotypes P-2, P-9, P-30 and P-52 were crossed to a tall-stem inbred line Uniwersalne 145 (S₁₇). The genotype P-2 was additionally crossed to a related, but tall-stem line P-2 W. In each cross combinations six generations - P₁, P₂, F₁, F₂, B₁ (F₁ × P₁) and B₂ (F₁ × P₂) - were examined. Distribution of plant height in hybrid generations had a continuous character, which indicated a polygenic determination of short stem in all "P" genotypes under study. Results of the genetic analysis (degrees of dominance, Burton method, Mather and Cavalli scaling tests, a six-parameter model of inheritance) showed a significant role of additive, dominant and epistatic gene action in genetic determination of short stem in the "P" genotypes. Only in the cross Uniwersalne 145 × P-52 one of the applied methods (a six-parameter model) has not confirmed a significant role of epistasis and dominance. In the cross combinations Uniwersalne 145 × P-2, Uniwersalne 145 × P-9 and Uniwersalne 145 × P-30 a reduction of the plant height was influenced by homozygote × homozygote and homozygote × heterozygote interactions as well as by dominance effects, whereas the plant height increase was influenced by heterozygote × heterozygote interaction as well as by effects of additive gene action. The combination P-2W × P-2 was found to have reverse relationships. The revealed epistasis had a duplicate character. The heritability of plant height was relatively high and varied from 70.4% to 84.9% depending on the cross combination.

Opis:
Artykuł przedstawia metody zaawansowanej analizy wizualnej, która nie polega jedynie na badaniu podstawowych, statystycznych własności szeregów czasowych, ale przede wszystkim na próbie wykrycia pewnej złożonej, ukrytej w nich struktury. Uzyskanie takich informacji nie jest możliwe na podstawie podstawowych badań statystycznych danych szeregu czasowego ani jego wykresu w postaci pierwotnej, który jest w rzeczywistości kompletnie nieczytelny. Współczesna analiza szeregu czasowego często przypomina przepuszczenie danych szeregu przez pewien pryzmat oraz przedstawienie wyników na odpowiednio skonstruowanym wykresie w celu wizualnej identyfikacji jego określonych własności. Istnieją również metody dwustopniowe, które dodatkowo zawierają analizę ilościową i możliwości szacowania specjalnych wskaźników uzyskanych wyłącznie na podstawie takich wykresów, które same niosą wiele przydatnych informacji i mogą stanowić wskazówki przy wyborze innych metod i narzędzi badawczych (por. np. metody Recurrence Quantification Analysis lub Artificial Insymmetrised Patterns). Metody te pozwalają na odróżnienie badanego szeregu czasowego od losowego szumu, wykrycie zakłóconych procesów deterministycznych, ocenę rodzaju zależności w nim występujących, określenie stopnia stacjonarności, determinizmu i rekurencji. Mogą także pomóc w doborze metod pozwalających wykryć w danych elementy nieliniowości (a nawet chaosu deterministycznego). Inną zaletą tego podejścia jest możliwość ujawnienia w danych cykli okresowych o różnych długościach (co pozwala na bardziej skuteczne stosowanie modeli ARIMA lub wyrównywania wykładniczego, gdzie okres składnika cyklicznego musi być znany i może być wykorzystywany w pewnych modelach teoretycznych, np. średnich ruchomych lub autokorelacji). Takie własności nowoczesnej wersji metod wizualnej analizy szeregów czasowych musiały wzbudzić zainteresowanie badaczy skomplikowanych zjawisk i procesów ekonomicznych, którzy próbują je wykorzystywać do pogłębionej analizy nieliniowej, a także do efektywnego modelowania i prób prognozowania tych procesów. Jest to również powód przedstawienia urozmaiconego przeglądu tych metod w niniejszym artykule.
The paper presents an advanced visual analysis method that does not rely only on examining of basic statistical properties of the time series, but also on attempting to detect a complex structure, hidden in the original dynamic process. Obtaining such information is not possible on the basis of the basic survey of time series data, or its graph in the original form, which is in fact completely illegible. Contemporary time series analysis of time series data is often reminiscent of passing it through a prism, and presenting the results on a properly constructed plots for visual identification of its specific properties. There are also two-step methods, which include both the possibility of quantitative analysis and estimation of specific indicators derived on the basis of such plots. They can carry a lot of useful information and provide us the guidance for the further selection of proper research of nonlinear analysis methods and tools (see eg. the methods of Recurrence Quantification Analysis and Artificial Insymmetrised Patterns). These methods allow to distinguish the analyzed time series from the random noise, to detect real deterministic processes biased with noise, to assess the type of dependencies in time series data, and to determine the degree of stationarity, determinism or recurrence. They can also help in the selection of methods to detect the nonlinearity in the data (or even deterministic chaos). Another advantage of this approach is the possibility of disclosure in data periodic cycles with periods of different lengths (for more efficient use of ARIMA and exponential smoothing models, where the period of the cyclical component must be known and can be used in certain theoretical models, eg. moving average or autocorrelation). Such properties of the modern version of visual time series analysis caused the interest of scientists trying to understand the complex economic phenomena and processes. They are trying to use it for in-depth nonlinear analysis, economic modeling and attempts of effective forecasting of these processes. This is the main reason for presenting a review of these methods in this paper.

Opis:
This paper analyses the long-term coverage (1990–2014) of German reunification by six German newspapers. Our quantitative content analysis shows how often the press covers the event, what the content of the coverage is, and how journalists evaluate the reunification process. As we have analysed newspapers of different locations, ranges, types, and editorial lines, we can see whether newspapers cover German reunification differently. Our analysis shows that the amount of coverage of reunification quickly decreases, and only a few articles are published prominently. The press reports on more differences between East and West Germany than similarities; about one third of the articles mentions problems and conflicts, although they become less important over time. All in all, positive evaluations of German reunification outweigh negative judgments and increase over time. We see evidence that the placement, content, and tone of coverage highly depends on the type, editorial line, range, and location of newspapers.

Opis:
The aim of the study is to discuss QEEG method in the context of its usefulness for confirming neurodevelopmental disorders, and evaluating the effectiveness of psychiatric and/or psychological interventions, based on a review of available literature. It attempts to determine the applicability of this method in child and adolescent psychiatry. QEEG is quantitative analysis of EEG record using statistical processing of the signal. This method is commonly used to prepare therapeutic recommendations for neurofeedback training. Attempts at implementation of QEEG in diagnosis of various diseases have been increasingly often described in foreign studies. This also applies to psychiatry. Most reports still tackle attention deficit hyperactivity disorder (comparison of the effects of neurofeedback therapy and pharmacological interactions, distinguishing subtypes of the disease). Other analyses are concerned with diagnosing mental illnesses, differentiating their subtypes, predicting effects of pharmacological therapy, comparing the effectiveness of different treatments. Studies of patients with depression and schizophrenia are also becoming popular. QEEG has proved useful in determining the efficacy of pharmacological treatment of depression. According to the researchers, this method enables prediction of schizophrenia, differentiation of its subtypes, and determining the effectiveness of its treatment. There are studies devoted to the analysis of changes in EEG characteristic of methamphetamine addiction or eating disorders. There is, however, little research regarding the use of this method in child and adolescent psychiatry, even though there obviously exist many studies related to the use of QEEG in neurofeedback therapy in the youngest patients with attention deficit hyperactivity disorder, or studies on the effectiveness of various types of medications used in the treatment of this disease. One study discussing EEG biofeedback training in autistic children has also been published. It seems necessary to expand research on the use of quantitative QEEG in work with children and adolescents suffering from psychiatric entities.
Celem pracy jest omówienie metody QEEG w kontekście jej przydatności w stawianiu diagnozy psychiatrycznej oraz monitorowaniu skutków oddziaływań psychologicznych i/lub psychofarmakologicznych na podstawie przeglądu dostępnego piśmiennictwa. Autorki starały się określić zastosowania omawianej metody w psychiatrii dzieci i młodzieży. QEEG polega na ilościowej analizie zapisu EEG za pomocą obróbki statystycznej sygnału. Metoda ta jest powszechnie wykorzystywana w celu przygotowania zaleceń terapeutycznych do treningu neurofeedback. Za granicą coraz częściej pisze się o próbach wdrażania QEEG w diagnostyce różnych chorób – także psychicznych. Większość doniesień nadal dotyczy zagadnień nadpobudliwości psychoruchowej z deficytem uwagi (porównanie skutków neurofeedbacku i oddziaływań farmakologicznych, odróżnianie podtypów choroby). Inne analizy odnoszą się do diagnozowania chorób psychicznych, różnicowania ich podtypów, przewidywania skutków leczenia farmakologicznego, porównania skuteczności poszczególnych metod leczenia. Popularne stają się badania nad pacjentami z depresją i schizofrenią. QEEG okazało się przydatne w ocenie skuteczności farmakoterapii depresji, według badaczy umożliwia też przewidywanie zachorowania na schizofrenię, różnicowanie jej podtypów i określanie skuteczności leczenia. Istnieją badania poświęcone analizie zmian w zapisie QEEG charakterystycznych dla uzależnienia od metamfetaminy i dla zaburzeń odżywiania. Mało jest natomiast analiz na temat użycia tej metody w psychiatrii dzieci i młodzieży – z wyjątkiem badań, które odnoszą się do roli QEEG w terapii neurofeedback pacjentów z zespołem nadpobudliwości psychoruchowej z deficytem uwagi czy skuteczności typów leków używanych w terapii tej choroby. Znaleziono jedną pracę poruszającą problematykę dzieci z autyzmem (w odniesieniu do treningu EEG biofeedback). Konieczne wydaje się poszerzenie badań o zastosowanie ilościowego QEEG w pracy z dziećmi i adolescentami cierpiącymi na choroby psychiczne.
