Opis:
Z dozą przekonania należy wskazać, iż dobro dziecko powinno być priorytetem we wszystkich ustawodawstwach. Z tego względu wszystkie państwa świata powinny zapewnić, by ich ustawodawstwo było skonstruowane w sposób, który chroni bezbronne podmioty ochrony, czyli dzieci. Stres u dziecka może być spowodowany wieloma czynnikami. Do jednych z nich zaliczyć można sytuację, w której dziecko jest świadkiem w sądzie. Niektóre dzieci dobrze sobie radzą z tą nową sytuacją, niektóre z kolei mogą odczuwać dyskomfort. Dlatego kwestia ochrony dziecka (w skład której wchodzą różne aspekty), powinna być priorytetem. Celem niniejszego artykułu jest zaprezentowanie regulacji dotyczących tych kwestii w wybranych państwach z poszczególnych kontynentów. Artykuł prezentuje ustawodawstwo takich krajów, jak: Polska, Japonia, Malezja, RPA, Kenia, Nowa Zelandia, Jamajka, Tuvalu, Stany Zjednoczone, w zakresie problematyki dotyczącej zeznań dziecka. Bez wątpienia stwierdzić należy, iż w ustawodawstwie poszczególnych krajów odnaleźć można zarówno wiele punktów zbieżnych, jak i różnic.
All countries need to ensure that their laws are regulated in a way that promotes the interests of the child, because the welfare of the child must always take priority. There is no doubts that being a witness can be stressful – some children can find it stressful. The aim of this article is  to present the regulations in different countries: Poland, Japan, Malaysia, RSA, Kenya, New Zealand, Jamaica, Tuvalu, United States of America. What is important, legislators should look at this issue in a sensitive and proper manner.

Opis:
The objective of this study was to measure and correlate the solubility of pyrimidine derivatives in five different solvents namely chloroform, N,N-dimethylformamide, tetrahydrofuran, 1,4-dioxane and ethyl acetate from 298.15 to 328.15 K under atmospheric pressure of 0.1 MPa using gravimetric method. The characterization of all the synthesized compounds was done by IR, NMR and mass spectra. The modified Apelblat and Buchowski-Ksiazczak λh equations were used to correlate the experimental solubility data. Using Van’t Hoff and Gibb’s equations, some thermodynamic parameters such as Gibb’s free energy, enthalpy and entropy of dissolution were evaluated from solubility data. It is found that solubility increases with temperature.

Opis:
In this study, instead of gasketed or brazed plate heat exchangers, which are used in various fields of application, a direct metal sintering method is used to design a heat exchanger with its original geometry and with different geometries. Studies of heat exchangers found in published literature were reviewed, and the thermal behaviors of the proposed unique designs were examined. Usually heat exchangers using this design do not use channel spacing angles of 30-45-60-75° for the plate ducts. The thermal behaviors of the fluid-circulating systems were analyzed using ANSYS FLUENT software, and they used the boundary conditions found in the literature for this design. Heat transfer between the heat exchanger channels and channel walls was calculated. The analyses results show that an increase in the amount of heat transfer surface area and also an increase in surface roughness increased the amount of positive heat transfer.

Opis:
The objective of this study was to evaluate the diagnostic accuracy of sonoelastography in patients of primary and secondary health care settings. Google scholar, PubMed, Medline, Medscape, Wikipedia and NCBI were searched in October 2017 for all original studies and review articles to identify the relevant material. Two reviewers independently selected articles for evaluation of the diagnostic accuracy of sonoelastography in different diseases based on titles and abstracts retrieved by the literature search. The accuracy of sonoelastography in different diseases was used as the index text, while B-mode sonography, micro pure imaging, surgery and histological findings were used as reference texts. Superficial lymph nodes, neck nodules, malignancy in thyroid nodules, benign and malignant cervical lymph nodes, thyroid nodules, prostate carcinoma, benign and malignant breast abnormalities, liver diseases, parotid and salivary gland masses, pancreatic masses, musculoskeletal diseases and renal disorders were target conditions. The data extracted by the two reviewers concerning selected study characteristics and results were presented in tables and figures. In total, 46 studies were found for breast masses, lymph nodes, prostate carcinoma, liver diseases, salivary and parotid gland diseases, pancreatic masses, musculoskeletal diseases and renal diseases, and the overall sensitivity of sonoelastography in diagnosing all these diseases was 83.14% while specificity was 81.41%. This literature review demonstrates that sonoelastography is characterized by high sensitivity and specificity in diagnosing different disorders of the body.
Celem badania była ocena dokładności diagnostycznej sonoelastografii u chorych leczonych w warunkach placówek podstawowej i specjalistycznej opieki zdrowotnej. W październiku 2017 roku dokonano przeglądu baz danych Google Scholar, PubMed, MEDLINE, Medscape, Wikipedia oraz NCBI w celu pozyskania prac oryginalnych i poglądowych, które stanowiły materiał do badania. Prace wybierało dwóch badaczy niezależnie. Oceniono dokładność sonoelastografii w diagnostyce różnych chorób na podstawie tytułów i streszczeń wyszukanych prac. Główny termin stanowiła „skuteczność sonoelastografii w diagnostyce różnych chorób”, a terminy „ultrasonografia w trybie B-mode”, „obrazowanie MicroPure”, „zabieg operacyjny” i „wynik badania histopatologicznego” stosowano jako terminy referencyjne. Badane patologie dotyczyły: powierzchownych węzłów chłonnych, guzków okolicy szyi, złośliwych guzów tarczycy, łagodnych i złośliwych zmian w węzłach chłonnych szyjnych, guzków tarczycy, raka gruczołu krokowego, łagodnych i złośliwych zmian w piersiach, chorób wątroby, zmian w śliniankach przyusznych i gruczołach ślinowych, zmian w trzustce, chorób układu mięśniowo-szkieletowego oraz chorób nerek. Pozyskane przez dwóch badaczy dane dotyczące charakterystyki ocenianych prac oraz wyniki analizy przedstawiają tabele i ryciny. W sumie wyszukano 46 badań dotyczących zmian w piersiach, węzłów chłonnych, raka gruczołu krokowego, chorób wątroby, chorób gruczołów ślinowych i ślinianek przyusznych, zmian w trzustce, chorób układu mięśniowo-szkieletowego i chorób nerek, a ogólna czułość i swoistość sonoelastografii w diagnostyce tych chorób wynosiły odpowiednio 83,14% i 81,41%. Niniejszy przegląd literatury wskazuje na wysoką czułość i swoistość sonoelastografii w diagnostyce różnych chorób.

Zawiera analizę porównawczą historii komunizmu w Czechosłowacji oraz – w mniejszym zakresie – w innych krajach bloku wschodniego: pojedyncze artykuły dotyczą Polski, Węgier, Rumunii, Bułgarii i NRD. Uzupełnia stan badań nad komunizmem analizowanym z perspektywy transnarodowej i pomaga zrozumieć doświadczenie, które było udziałem kilku generacji Europejczyków. Autorka szkicu podkreśla wysoki poziom publikacji i jej nowatorstwo w zakresie oparcia naukowego wnioskowania na doświadczeniach potocznych obywateli bloku wschodniego.
The reviewed volume, Perceptions of Society in Communist Europe. Regime Archives and Popular Opinion, was written as a part of a long-term project headed by Muriel Blaive, the editor of the publication. The book included a comparative analysis of the history of communism in Czechoslovakia and to a lesser extent also inother countries of the bloc: single articles concerning Poland, Hungary, Romania, Bulgaria and the GDR. The reviewed book complements the existing state of research on communism from a transnational point of view and helps to better understand the experience that was shared by several generations of Central and Eastern Europeans. The author of the article underlines high level of the reviewed publication and draws attention to methodological innovation which is exploit a common experience of citizens of communist countries as a part of scientific inference.

Opis:
In the current study attention has been focused on the evaluation of different methods of measurement of bacterial adhesion to the metal surfaces with different chemical composition. The direct methods, which included determination of the number of bacterial cells using fluorescence microscopy and Colony Forming Units (CFU) on agar medium, and indirect methods using Alamar Blue (AB) and MTT assays, were evaluated. The chemical compositions of the metal surfaces included: copper, iron, chromium and nickel. Interaction effects of assay and metal compound have been specifically demonstrated in this study. It was found that metal ions reacted with components of the indirect colorimetric tests used in his study (AB and MTT assay). Consequently, those tests gave positive false results. In contrast to the indirect methods, direct counting methods such as microscopy techniques and CFU counting, were successfully applied for evaluation of bacterial adhesion to the metal surfaces. However, considering the limits for the surfaces of the examined samples for microscopy, the determination of the CFU was found to be the best method for testing the adhesion to metal surfaces. The method, combined with the appropriate detachment procedures allowed for a precise determination of the number of bacteria on the entire surface of the evaluated metal samples.

Opis:
Tyre-to-road adhesion has a great influence on transmitting forces between wheels and road surface and in the consequence on the safety of automobile motion. It plays significant role in vehicle motion modelling, especially for the needs of traffic accidents reconstruction and the development of active safety systems in automobiles. Simultaneously, the knowledge about tyre-to-road adhesion is limited, especially in case of the differences between anti-slip properties of summer and winter tyres. In the paper, method of the measurement of tyre-to-road adhesion coefficient is presented. The measurement system SRT-4 consists of special dynamometer trailer, towing vehicle and test-measuring equipment. It was designed for the needs of road engineering and further developed in the Institute of Vehicles of Warsaw University of Technology. It enables to obtain adhesion characteristics, i.e. graph of adhesion coefficient as a function of wheel slip ratio. In the article, examples of tyre-toroad adhesion characteristics and velocity characteristics of peak adhesion coefficient for different types of tyres (summer, winter) in different weather conditions are presented. Differences in characteristics courses caused by tyre type and weather conditions are discussed. For instance, in case of winter tyres it was noticed that their peak value of adhesion coefficient was reached for higher values of slip ratio than it was observed for summer tyres.

Opis:
Artykuł przedstawia tezę (postawioną przez Alasdaira MacIntyre'a), że spór o znaczenie takich pojęć jak ‘tożsamość’, ‘podmiotowość’, ‘wolność’, jest nierozstrzygalny. Konflikty wokół nich opierają się na błędnym założeniu, że istnieje tylko jedna prawdziwa racjonalność. MacIntyre konfrontuje taką koncepcję (uniwersalizm) z podejściem, które przyznaje, że istnieje wiele różnych rodzajów racjonalności (zakorzenionych w różnych tradycjach). Pierwsza część artykułu prezentuje jak MacIntyre rozumie uniwersalność i tradycję Druga koncentruje się na takich pojęciach, jak tożsamość i wolność, rozwijanych przez dwie tradycje: liberalizm i etykę cnoty. Na koniec przedstawia wniosek, że czynnikiem odróżniającym od siebie te dwie tradycje jest fakt istnienia (nieistnienia) dóbr doskonałości.
The article presents thesis (claimed by Alasdair MacIntyre) that arguing about the meaning of such notions as 'identity', 'subjectivity', 'freedom' is unsolvable. These conflicts are based on a wrong concept that there is only one true rationality. MacIntyre confronts such concept (universalism) with that one which admits that there are many different types of rationalities (rooted in different traditions). The first part of the article shows his (MacIntyre) understanding of universality and tradition. The second focuses on such notions as identity and freedom developed in two traditions, liberlism and virtue ethics. In the end it presents the conclusion that the factor which distinguishes these two traditions is the fact of existing (not existing) goods of excellence.

Opis:
The events in Crimea and eastern Ukraine that took place due to the competition between Russia and the EU over possibilities for close cooperation have reinforced the perception of Russia as a key stakeholder in geopolitical upheavals in the post-Soviet sphere. It also served as a reminder that any settlement to political and territorial conflicts within the post-Soviet sphere would have to include Russia. While all other countries in the Eastern Partnership have since associated themselves with either the EU or Russia, Azerbaijan chooses to remain outside such formal obligations. The EU and Russia both have particular interests in Azerbaijan. Russia's interests in Baku lie primarily in it not becoming an alternative to Russia's energy market and remaining within its sphere of influence. The EU, in turn, wants closer ties with Baku since it considers it an alternative energy market to the unreliable Russia. Considering these competing interests of two different actors, this paper is an attempt to chart Baku's course of action in managing to pursue the 'multi-vector' approach. It manages to pursue this approach by playing off the diverging interests of the EU and Russia and bargaining between them.(original abstract)

Opis:
The following article addresses two reviews of post-doctoral publications, both of which are scandalous on formal and substantive levels. The key elements related to the issue are the same person (professor), acting both as a reviewer in one case, and as a committee chair in the other, along with two dramatically different final decisions concerning both post-doctoral applications. This review seeks to address two articles by Anna Bączkowska and a monograph by Dorota Zielińska-Długosz. Aside from a substantive evaluation, I address the issue of ethical conduct in relation to “Kodeks etyki pracownika naukowego” PAN (Polish Academy of Sciences Scolar’s Ethics Code). The ground of professional ethics is important not only in relation to both authors’ publications, but also to the process of post-doctoral degree procedure.

Opis:
We investigated the phenotypic variation of five morphological needle characters of Scots pine (Pinus sylvestris L.) in three populations. Two of the populations occurred in bogs and the third one formed a degraded fresh pine forest showing some features of a dry pine forest. The greatest variation was found in characters a (needle length), b and d, denoting the number of stomatal rows respectively on the convex and flat sides of the needle. Conversely, characters c and e (average number of stomata per 2 mm of needle length on the convex and the flat side of the needle) were stable, with little interindividual variation. The two bog populations and the dryland population exhibited different sets of character correlations. The interpopulation differentiational detected on the basis of morphological character expression was markedly influenced by both the different edaphic conditions, and the distinct genetic structure of the studied populations.

Opis:
Positive descriptor fractional discrete-time linear systems with fractional different orders are addressed in the paper. The decomposition of the regular pencil is used to extend necessary and sufficient conditions for positivity of the descriptor fractional discrete-time linear system with different fractional orders. A method for finding the decentralized controller for the class of positive systems is proposed and its effectiveness is demonstrated on a numerical example.

Opis:
Rudyard Kipling says in the Ballad of East and West: “East is East, and West is West; and never the twain shall meet.” Yet, he never expected that with the technological development in transportation and communication, the Westerners and Easterners that have quite different cultures respectively would meet so frequently nowadays in international settings. However, in a sense, Kipling is absolutely correct in that people with different cultural patterns (including beliefs, values, attitudes, norms, customs, and material aspects), especially those from East and West, do encounter communication difficulties, breakdowns, misunderstandings and even conflicts and confrontations just because they fail to understand each other in their intercultural communication. The study of intercultural communication is not something new. However, the perspective from which the author probes into the problematic interaction between Easterners and Westerners is something different. In the paper, the author compares some major cultural patterns: high-context communication vs. low-context communication, individualism vs. collectivism, equality vs. hierarchy, and assertiveness vs. interpersonal harmony. Each of these cultural patterns is defined by examples, two opposite patterns are contrasted, and then potential problems are presented, thus making quite obvious the differences between East and West and their possible consequences in the intercultural communication. Understanding these cultural patterns or orientations which underlie most common behavior of the Easterners and Westerners helps us to see beneath the surface to find out why people from East and West act as they do. This discovery may lead us to appreciate the rich diversity and genius that exist in different parts of the globe, avoid potential intercultural problems and become successful communicators in the interaction between East and West.

Opis:
Yellow lupin seeds cv. Juno were stored under laboratory conditions for 2 month, 4, 6 and 8 years. Eighteen soluble carbohydrates were identified in embryonic axes and cotyledons of different age seeds. The concentration of soluble carbohydrates in analysed seeds ranged from 25 to 34% of dry mass. Axes contained more carbohydrates than cotyledons. Stachyose dominated in axes, and verbascose - in cotyledons. Other detected galactosides were: galactinol, galactosyl pinitols and galactosyl chiro-inositols (fagopyritols), but their content was several-fold lower than that of RFOs (in both axes and cotyledons tissues). The concentration of soluble carbohydrates indicated, that sucrose to RFOs mass ratio, or other changes in sugars composition are not indicators of seed storage.

Biotechnology is a very significant technology for todays economy and is quite often called the base of bioeconomy. It is very common practice to use the colors for description of different branches of modern biotech: red, green and white as well as violet biotechnologies for health, agriculture, industry and legal and social aspects, respectively. There are several critical aspects for future development of bioeconomy in Poland as well as in many other countries, for example: legislation including the intellectual property rights and public perception. It will be of critical value for our country to be not only and exclusively the consumer of the products of innovative industry, but also the participant in the production of biotechnological goods and services.

Opis:
School textbooks written by a Spanish erudite and pedagogue Juan Luis Vives were used in schools of Protestant denominations in Royal Prussia – in Gdańsk, Toruń, Elbląg, but also in other towns and cities of the Polish-Lithuanian Commonwealth– for teaching Latin. Nicolaus Volckmar, of German descent, a Polish language teacher at the Academic Gymnasium in Gdańsk, utilized the structure and themes of Vives’ dialogues Exercitatio linguae latinae  (1538) for teaching the Polish language. In this manner, paradoxically, the “phrasebook” of the Spanish humanist, as well as its subsequent editions, still in the 18th century was used by Gdańsk schoolers of German origin to learn the language which they needed for everyday communication in the community of multi-cultural and multi-ethnic Gdańsk. The Vives-Volckmar phrasebook was undoubtedly used by Arnold von Holten, later a lifetime mayor of the city, sent on a diplomatic mission to Spain by the Hanseatic League.

Opis:
We wszelkich opracowaniach z zakresu dobrego rządzenia zakłada się, że istnieje jeden jedynie słuszny model sprawnego państwa. Wpływa on izomorficznie na rozwój państw, których rządy są skłaniane do przyjęcia tego jedynego podejścia na rzecz osiągnięcia celu. W poniższym artykule kwestionuję tezę, że taki jedynie słuszny model w ogóle istnieje, uznając, że nawet nie przybliża nas on do tego, czym jest tzw. sprawne państwo. Państwa to bardzo zróżnicowane organizmy i struktury, nawet jeśli zwykliśmy określać je mianem modelowych. Mój wniosek oparty jest na badaniach praktyk zarządzania finansami publicznymi zarówno w krajach OECD, jak i państwach spoza tej organizacji. Badania ukazują, że sprawne państwo wcale nie musi charakteryzować się lepszymi praktykami zarządzania wynikającymi z wdrożenia "jedynie słusznego" modelu. Dobre zarządzanie finansami publicznymi w każdym kraju oznacza co innego. Konkluzją artykułu jest stwierdzenie, że model dobrego rządzenia umożliwia wyłącznie dostęp do swoistego "menu", a rozwój społeczeństwa należy badać, zadając sobie pytanie, dlaczego różne państwa wybierają z owego "menu" różne pozycje.
Work on good governance implies a one-best-way model of effective government. This has isomorphic influences on development, whereby governments are influenced to adopt a one-size-fits-all approach to get things done. This article challenges whether such an approach exists, proposing that models actually do not hold even for the so-called effective governments. Governments look different, even if they are similarly called models of good government. This proposition is examined through a study of public financial management practices in a set of Organisation for Economic Co-operation and Development (OECD) and non-OECD countries. The study shows that effective governments are not more likely to exhibit better practice characteristics implied in one-best-way models. Good public financial management means different things in different countries. The article concludes by suggesting that good governance models give way to menus and the development community invest more time in examining why different countries select different menu items.

Opis:
A text from the age of great debates on the scientific status of research based on material considered by many historians to be of questionable value. In his paper, Alessandro Portelli deals with the doubts and accusations made not only then, but also today, wherever “the phantom of spoken history” shows up. This manifesto of sorts has great educational value, since it organises and explains the issues of epistemological and technical nature fundamental for oral history, including the reliability of oral sources, the consequences of their oral nature and the role of transcription, and finally, the objectivity of the message.

Opis:
The article asserts the need for organizations to adopt intentional and transformative Global Inclusion, Diversity, Belonging, Equity, and Access (GIDBEA) practices, to ensure their future readiness. The research developed reaffirms the benefits of GIDBEA strategies in identifying gap areas and navigating crises, by providing insights on how to successfully embed a ‘new different’ GIDBEA strategy into organizational frameworks. By drawing trends across the 2020-2021 COVID-19 pandemic and other previous health and economic crises, it is indicated what is described as the “normality of disruption” and the need to move away from the idea of a ‘new normal’ to a new different. The new different acknowledges that the ‘normal’ or the status quo was often challenging for many. The impact and importance of the disruptions that individuals, communities, nations, etc., all have and will face together, is also recognized. The new different emphasizes organizational transformation through co-creation, sustainability, adaptivity, resilience, and design thinking. By implementing a design thinking model, GIDBEA proactively engages mistakes while promoting innovation through dissent and disruption. As a result, disruptions are not considered episodic crises but as recurring, expected, and presenting opportunities. Furthermore, it is argued that GIDBEA expertise is essential for remaining agile, innovative, and providing strategic organizational architecture to prepare and innovate for these disruptions. However, it is necessary to consider that GIDBEA practice can be limited due to the failure of organizations and leaders to frame it as an asset and develop strategic plans to leverage it in the same way they do other critical functional business units. Therefore, unless prioritized and conducted intentionally, GIDBEA work will not achieve its promised bonuses and transformative potential. The article offers readers insights and tools to assess existing GIDBEA within their organization. Using metaphors of “construction” and “architecture,” it illustrates how reimaging organizational architectures and constructing initiatives focused on GIDBEA are fundamental to resiliency, organizational sustainability, and the ability to thrive through shifting landscapes.

Opis:
There are many different definitions of the group of circular units of a real abelian field. The aim of this paper is to study their relations in the special case of a compositum k of real quadratic fields such that -1 is not a square in the genus field K of k in the narrow sense. The reason why fields of this type are considered is as follows. In such a field it is possible to define a group C of units (slightly bigger than Sinnott's group of circular units) such that the Galois group acts on C/(±C²) trivially (see [K, Lemma 2]). Due to this key property we can easily compare different groups of circular units (see the conclusion of this paper).

Opis:
Successful vegetable cultivation begins with quality seedlings. Some quantitative parameters such as stem diameter (g), seedling dry weight (g) and specific leaf area (cm2 g–1) are used to determine the quality of seedlings. In this study, the effects of different seedling production systems (traditional and floating system), organic fertilizers (M – manure, B – blood fertilizer from slaughterhouse and O – commercial organic fertilizer) and seed tray cell size (ST1 – 2.2 × 2.2 cm and ST2 – 3.1 × 3.1 cm) on seedling quality of tomato, were investigated. It was determined that the most effective results in applications of BST1 and MST2, were obtained in terms of leaf dry weight (0.39 g), stem dry weight (0.15–0.16 g) and root dry weight (0.10–0.11 g). At the end of the study, the big celled seed tray, blood and manure fertilizers were significantly higher (P ˂ 0.01) than grown in the small celled seed tray and control plants.

Opis:
The hydroponic system is very often used for greenhouse vegetable production. The flood irrigation on a bench or on the flood floors is applied in the production of ornamental plants and vegetable transplants. This system is environmentally friendly, since fertigation is used in a closed system using the recirculation of nutrient solution. The aim of this study, conducted in 2010-2012, was to determine the effect of flood fertigation with different concentrations of nutrient solution (EC: 1.0; 2.0; 3.0; 4.0 mS cm-1) on the yield and quality of the butterhead lettuce cultivar Natalia grown in different substrates (coconut coir, peat and rockwool). The experiment was conducted in the spring and autumn cycle. The highest marketable yield at each concentration of the nutrient solution was achieved in the cultivation in rockwool, both within the spring and autumn. The highest nitrate content in lettuce in terms of both cultivation cycles was found in the lettuce grown in the nutrient solution concentration of EC 4 mS cm-1, and the lowest one was achieved in the nutrient solution concentration of EC 1.0 mS cm -1. Significantly less of nitrates was in lettuce grown in spring than in autumn. Higher levels of EC significantly increased the content of P and K in lettuce leaves during in both growing cycles, while the content of Ca and Mg was not significantly different. The applied substrates had a significant impact on the content of K, P, Ca and Mg in leaves of lettuce. The best concentration of the nutrient solution used for flood fertigation of greenhouse lettuce was EC 3.0 mS cm-1 for the spring cultivation and EC 4.0 mS cm-1 for the fall crop.

The effects of different types of arbuscular mycorrhizal (AM) fungi on the root inoculation and plant elemental content of lupin (Lupinus albus L.) were investigated in the present study. The growth and development of lupin were examined to determine the species of AM fungi that can help to grow lupin with a high protein content and economic value. In this study, which was carried out as a pot experiment under controlled greenhouse conditions, first the pots were inoculated with Glomus geosporum, Glomus mosseae, Glomus caledonium, Glomus etunicatium mycorrhizal spores and then lupin (Lupinus albus) seeds were sown. The plants were watered with pure water during the experiment. The trial was terminated after a 60-day plant gowing period. In the study, inoculation occurred at lupin roots at rates varying between 13.3 and 30.0%. However, there was no statistically significant difference among the types of arbuscular mycorrhizal fungi applied to the plant in the inoculation rate. The examination of the effect of the application of different AM (Glomus geosporum, Glomus mosseae, Glomus caledonium, Glomus etunicatium) spore on the plant development showed that AM inoculation did not have an effect on the lupin development. The effect of AM inoculation on the plant’s nutrient content revealed no significant difference in the content of crude protein, P and K, while demonstrating a significant increase in the sulphur and magnesium content versus the control. The plant content of crude protein varied between 185.6 and 226.5 (g kg-1), phosphorus – 0.61-0.74 (g kg-1) and potassium – 9.6-11.1 (g kg-1). The concentrations of Zn, Cu, B and Mo in lupin did not show statistically significant modifications caused by the inoculation of different types of AM. However, the plant Mn content showed a decrease due to AM inoculation, whereas a significant increase was observed in the Na content after AM inoculation. AM fungi were observed in plant roots after the inoculation with any of the four different types of mycorrhiza. But no positive effects of mycorrhizal inoculation were not observed on crude protein and the uptake of plant nutrients.

Opis:
Observations made in geodetic network must be processed in order to find the parameters that we search for, such as coordinates of points or their displacement. In practice, the most popular method used for this purpose is the least squares adjustment. However, according to research, it is susceptible to gross errors in observations. In recent years, the so-called robust estimation methods have gained great popularity. In these methods, the impact of gross errors is eliminated by iterative modification of observation weights. One of these methods is Huber’s robust estimation, in which the objective function is a spline. For observations with residuals within the assumed range, the component of the objective function is identical to objective function in the method of least squares. However, for the remaining observations the component of the objective function is similar to that in the least absolute deviations method. In literature, various ways of implementation of Huber’s method have been described. The study presents results of numerical analyses of effectiveness of Huber’s method. Various approaches to weight modification, described in literature, have been applied. Conclusions on research conducted have been presented.

Salt stress is one of the most severe environmental factors that reduces and limits growth and development of plants. Abiotic stresses such as heavy metals, salinity, drought, temperature, UV-radiation, ozone causes drastic yield reduction in most of the crops. Especially salt stress affects around 20 of NaCl on germination and seedling growth of Zea mays L. Seeds of Zea mays were germinated in glass Petri- 100 × 15 mm diameter lined with blotting paper. Ten seeds were placed in each petri-dish. Petridishes were irrigated with 25, 50, 75, 100, 125, 150, 175 and 200 mM concentrations of NaCl. A control was moistened with ten milliliters of distilled water. The germination percentage, water absorption of the seeds, water uptake percentage and the growth parameters were observed. The results obtained showed that the inhibition of the germination percentage, germination rate, water uptake, growth and biomass accumulation of the seedlings were observed to decrease with increasing NaCl concentrations. At the highest level of stress both plumule and radical decreased significantly. The salt stress decreased seed germination, biomass and growth of maize seedlings due to ion toxicity, decrease osmotic potential and oxidative stress.

Opis:
Difficulties resulting from the social perception of people with disabilities, and the personal assessment of their own disability are important for her/his relationship with other people. Therefore, it is worth asking what the perceptions are, of those who experience psychosocial effects due to their physical disability, towards people with intellectual disabilities, hearing impairments, visual impairments, mental illnesses, as well as their own physically disabled group. To analyse the perception of people with a physical disability, the study explores three areas: the acceptance or rejection of society’s stigmatization towards persons with disabilities; integrative versus separative social orientations of people with physical disability; social preferences of people with physical disability regarding other disabled people. The research sample consisted of 75 people with physical disabilities, who suffer from damage to the locomotor system. The data was collected using a questionnaire The findings highlight that the response from those who were physically disabled agreed with the opinions of general society, not only with the issue of promoting integrated solutions and offering assistance, but also having the same preferences and opinions about specific types of disability. However, their perception regarding their own group was noticeably different from that of general society.

We begin reasons why high system availability is important. Furthermore, the basic terms are introduced pertaining to the availability with particular review of the parallel structure. Then the availability of different wavelength division multiplexing (WDM) systems is analysed: point to point, chain and ring with 1+1 protection of the wavelength channel, plus the influence of availability of nodes and links on the total system availability. The data on failure intensity and mean time to repair of certain components were taken from various literature sources. We assumed in the analysis a WDM system with 16 wavelengths and 2.5 Gbit/s capacity per wavelength channel. Finally, results of calculation and comparisons of availability of different WDM systems and proposals for improvement of their availability are presented.

The current study was designed to assess the presence of deception indicators in truthful and deceptive statements. Four independent raters watched 80 statements on three different topics and evaluated the presence of 11 different cues to deception. It was hypothesized that it would be impossible to accurately differentiate between truthful and deceptive statements based on raters’ evaluation and that the ratings of credibility would be based on stereotypical beliefs about cues to deception rather than on the objective indicators of deception. Moreover, different deception topics would result in different patterns of indicators. The results partially supported the hypothesis – the raters’ evaluations did not make it possible to differentiate truth from lies; however, it was usually the objective cues that were used to predict the credibility of statements. Moreover, different accounts resulted in different patterns of cues to deception.

In this study, it was aimed to determine the effects of vermicomposts (VC) obtained from different mixture rates of same feedstocks on growth and N, P, K nutrition of wheat plant grown on alkaline and acidic soils. For this, 0, 5, 10 and 20 t ha-1 vermicomposts were mixed to the 2 kg soil containing pots. Study was conducted as greenhouse experiment for 3 months. In alkaline soil, VC differences significantly affected plant dry weight (DW) and N, P and K concentrations. Application doses significantly affected plant DW, P and K concentrations. Also, VC x dose interaction had a significant effected on plant P and K concentrations. In acidic soil, application doses affected all parameters significantly. At the same time, vermicompost types had a significant effect on P and K. Interaction of VC x dose also had a significantly effect on N, P, and K concentrations of wheat. Effect types and degree of VC were different on alkaline and acidic soils. It was also seemed that the effect of VC on plant N, P and K nutrition was higher in acidic soil than that in alkaline soil.

The main aim of the study was to determine which of the viability and germination capacity of pollen grains estimation methods are optimal and to test if the studied sections and species within the Rosa genus are differentiated in pollen viability andgermination capacity. We analysedandcomparedpollen grains of 14 wild Rosa species using 5 viability tests and13 various liquidandagar media. Viability of pollen grains in the majority of the examinedspecies was greater than their germination capacity. The most viable pollen grains were foundin R. gallica (section Gallicanae), where average of 5 viability tests is 90.69%, andin R. pendulina (section Rosa) – 86.85%. Species from section Caninae have a lower level of viability (from 60.59% in R. rubiginosa to 31.23% in R. inodora). Pollen of species from sections Gallicanae (R. gallica; to 63.4%) and Rosa (R. pendulina; to 47.21%) germinatedmuch better than the pollen of the majority of species from section Caninae (with the exception of R. zalana; to 47.22%). The examinedpollen grains germinatedmost numerously on agar medium with 1.5% agar+15% sucrose+50 ppm boric acidandliquidmed ium with 15% sucrose+ 50 ppm boric acid. Following deep-freeze storage (–25°C) for six months, the pollen grains of nine selected species (with the exception of R. rubiginosa) showed viability higher or similar to that before storage.

A study was carried out on the leaf abscission zone from birch trees growing on polluted sites (two) and a non-polluted site (one). Samples for anatomical investigation were collected from six trees on each site, during three succeeding vegetation seasons. It was observed that in trees growing at the polluted sites: 1) maturation of the abscission zone was faster, 2) the protective layer was thinner and 3) the formation of leaf scar periderm was delayed in comparison with trees from the non-polluted site. The results obtained suggest that environmental pollution influences the formation of the abscission zone and the protection of the leaf scar.

Opis:
Satellite compass is the specific, multiantenna receiver of the satellite navigation system which, apart from the standard functions, like position, time, Course and Velocity etc. enable to measure the angles of the orientation of the ship's hull. The most popular solution is two-antenna solution, which gives opportunity to measure two angles: heading and pitch or roll. However, three antenna solutions are accessible as well (www.furuno.co.jp). In this option the device can measure full information about space orientation of the object. Discussed devices has common name 'compass' although they are still not officially confirmed in this role and according IMO's resolutions they can be used only as auxiliary source of information and is classified as Heading Transmitting Devices (MSC.116). The origin of satellite compasses we can find in interferometry used in astronomy since sixties, however the present solutions in fact are adopted from Real Time Kinematic variant of GPS technology (Felski 1999). Nonetheless products accessible on the shelf are very diverse in construction, electronics and software so in practice of their exploitation very different proprieties could be observed. In the report the practical experiences with the use of two different types of satellite compasses are presented, as well as the analysis of observed errors. It turned out that the behavior of satellite compass is not comparable to any gyro or magnetic compasses which are in fact something natural. In fact signal from satellite compass has three kinds of errors: first one is small noise with amplitude of same arc-minutes which is natural in any electronic devices, the second one is long-term changes which are seems be dependent on satellite constellation configuration and finally short, big changes correlated with transition period when new configuration of satellites is catches-on. According to the observations very important are solutions assumed in electronics and software, because observations confirm that two different constructions characterize themselves with very different proprieties.

Opis:
Background. Selenium belongs to important microelements. Numerous studies have revealed relationships between its deficiency and occurrence of diverse illnesses, but the question of the proper form and dose of Se-supplementation still remains unsolved. Objective. In the present study the influence of different selenium compounds on blood morphology and biochemistry as well as on phagocytic capacity of granulocytes and NBT test in rats was investigated. Material and methods. Adolescent male Wistar rats were divided into four groups (ten animals each): I – control, received saline; II – received sodium selenite Na2SeO3; III – received selenoorganic compound A of chain structure 4-(o-tolyl-)-selenosemicarbazide of 2-chlorobenzoic acid; IV – received selenoorganic compound B of cyclic structure 3-(2-chlorobenzoylamino-)- 2-(o-tolylimino-)-4-methyl-4-selenazoline. The administration was performed by stomach tube at a dose of 5 · 10-4 mg Se g-1 b.w. once a day for 10 days. Results. Selenium compounds treatment decreased haematocrit. Erythrocytes number was unchanged in all groups receiving Se vs. control, whereas leucocytes number was depressed in groups II and IV. Haemoglobin was significantly decreased in group III. White blood count was altered in groups II and III, where all parameters were markedly decreased except for lymphocytes in group III and remained unchanged in group IV. The outcomes regarding selenium effect on biochemistry parameters of blood showed that urea remained unchanged, glucose was statistically decreased in groups II and III, whereas cholesterol was significantly diminished in group II and increased in group III vs. control. Results concerning phagocytosis and NBT test displayed that % of positive cells were decreased in groups II and III, whereas remained unaltered in group IV vs. control. Conclusions. As cyclic selenoorganic compound B did not cause many significant changes of the studied parameters it may be suggested that after further researches it could be taken into account as a possible selenium supplement.
Wprowadzenie. Selen należy do mikropierwiastków o dużym znaczeniu dla organizmu. Badania naukowe wykazały istnienie zależności pomiędzy niedoborem selenu a występowaniem wielu poważnych schorzeń, jednakże kwestia doboru odpowiedniej formy i dawki stosowanej w suplementacji nadal pozostaje nierozwiązana. Cel. W przeprowadzonym doświadczeniu badano wpływ podawania różnych związków selenu na morfologię krwi i biochemię krwi oraz zdolności fagocytarne granulocytów i test NBT u szczurów. Materiał i metody. Młode szczury samce rasy Wistar podzielono na cztery grupy (po 10 zwierząt): I – kontrola, otrzymywała sól fizjologiczną; II – otrzymywała selenian(IV) sodu Na2SeO3; III – otrzymywała organiczny związek selenu A o budowie łańcuchowej 4-(o-tolilo-)-selenosemikarbazyd kwasu 2-chlorobenzoesowego; IV - otrzymywała organiczny związek selenu B o budowie cyklicznej 3-(2-chlorobenzoiloamino-)-2-(o-toliloimino-)-4-metylo-4-selenazolinę. Związki podawane były sondą dożołądkowo w dawce 5 · 10-4 mg Se g-1 m.c. raz dziennie przez okres 10 dni. Wyniki. Podawanie związków selenu obniżyło hematokryt. Liczba erytrocytów we wszystkich grupach pozostała niezmieniona w stosunku do kontroli a liczba leukocytów była zmniejszona w grupach II i IV. Poziom hemoglobiny został obniżony statystycznie w grupie III. Obraz białych elementów morfotycznych w porównaniu do kontroli uległ zmianie w grupach II i III gdzie wszystkie wskaźniki zostały istotnie statystycznie obniżone za wyjątkiem limfocytów w grupie III, natomiast w grupie IV nie zaobserwowano żadnych zmian. Analizując wpływ podawania selenu na parametry biochemiczne krwi stwierdzono, że stężenie mocznika pozostało niezmienione. Stężenie glukozy w przypadku grup II i III uległo istotnemu statystycznie obniżeniu. Stężenie cholesterolu w II grupie było istotnie obniżone a w III podwyższone w porównaniu z kontrolą. Badania fagocytozy i wyniki testu NBT wykazały, że % pozytywnych komórek uległ obniżeniu w grupach II i III w stosunku do grupy kontrolnej i pozostał niezmieniony w grupie IV. Wnioski. Ponieważ organiczny związek cykliczny B nie spowodował istotnych statystycznie zmian wielu badanych parametrów można byłoby sugerować, że przeprowadzenie dalszych badań pozwoli rozważyć jego zastosowanie jako suplementu selenu.

Opis:
Modern forestry management should be based on the principle of sustainability.In order to preserve habitat productivity, the amount of nutrients removed from the environment along with forestry products must be taken into consideration. This study shows the exact concentrations of chemical elements in different tree parts of Scots pine, growing on poor soils in north-western Poland. The observedvalues were compared to the values found in literature. In addition, the relationship between the concentrations of elements and stem diameter or stand density was researched. The highest concentration of chemical elements was observed in the needles (C, N, P, K, Mg, S, Mn, Na, Fe) and the lowest (C, N, P, S, Cu, Na, Ni, Pb, Zn, Fe) in the stem wood. Most of the macronutrients (P, K, Ca, Mg and S) reached optimal values, with the exception of N showing a deficiency, especially in the needles. The relationship between the content of elements and DBH or stand density was rather weak, and in both cases, negative.

Celem opracowania była analiza sposobów definiowania usług. Badanie przeprowadzono metodą krytycznej, chronologicznej i porównawczej analizy literatury. Uwzględniono publikacje o charakterze słownikowym, piśmiennictwo naukowe z dziedziny nauk ekonomicznych oraz dokumenty normalizacyjne. Przedstawiony w opracowaniu przegląd definicji terminu usługa pozwolił na sformułowanie następujących wniosków: (1) w literaturze funkcjonują definicje pojęć usługi oraz usług, (2) w piśmiennictwie z dziedziny nauk ekonomicznych (w szczególności marketingu) terminy usługa oraz usługi stosowane są zamiennie, (3) w dokumentach normalizacyjnych do 2015 r. usługa była traktowana jako wyrób niematerialny; obecnie stanowi kategorię odrębną. Wkład własny autorki obejmuje systematyzację pojęcia usługi w kolejnych etapach ewolucji tego terminu oraz podział definicji ze względu na źródła ich pochodzenia.
The aim of the article was the analysis of the ways of defining services. The study was conducted with the use of critical, chronological and comparative literature analysis. The dictionary-style publications, scientific literature in the field of economics and normalization documents were respected. The article presents the overview of services term definitions. This allowed to formulate the following conclusions: (1) in the literature definitions of both service and services terms can be found, (2) in scientific literature, in the field of economics (particularly marketing), the terms service and services are used interchangeably, (3) in normalization documents up to the year 2015 a service was treated as an intangible product; now it is recognized as a separate category. Author’s own contribution includes systematization of the term service in the following stages of its evolution and classification of definitions according to sources of their provenance.

Opis:
Different soil texture classification systems are used in Poland. The system most widely used in agriculture is named after Polish Soil Science Society (PSSS) and is described in the soil classification norm BN-78/9180-11 (BN1978 standard). The last edition of soil classification system and soil texture classes published by PSSS in 2008 (PSSS 2008 classification) is different from BN1978 standard. The aim of this paper is a quantitative and qualitative comparison of the compatibility of agronomic categories created according to the old textural classes (BN1978 standard) and the new textural classes (PSSS 2008 classification). The representative set of soil samples (n=316) for arable mineral soils in Poland were divided into agronomic categories according to these two soil classification systems. The agronomic categories, which comply with soil classification systems PSSS 1978 are widely used in agricultural advisory. The results of the study showed differences in the amount of soil samples classified for the corresponding agronomic category. The study also showed discrepancies in the fine particle (<0.02 mm) and colloidal fraction (<0.002 mm) content in the corresponding categories. The differences may affect the assessment of soil fertility in nutrients(abundance) such as potassium, magnesium and of soil liming needs, as well as appropriate determination of fertiliser doses.

Opis:
The author considers “religiosity” as a universal social phenomenon, whereas “religion” constitutes its particular, cultural form. The study presents particular characteristics of the Chinese religiosity and its essential differences with the Mediterranean religions. The five “constitutional” religions in PRC are presented (Buddhism, Taoism, Islam, and the Catholic and Protestant Churches), as well as the officially registered religions in Taiwan. The author outlines changing attitudes to them and their contemporary development. He indicates great variations in the estimations of their “believers”, and points out the difficulties in “counting” of so called “believers into Chinese religions”. He concludes that the majority of the Chinese practice something that is located beyond these “official”, or “institutionalised” religions, i.e. “popular beliefs”. In some respects they even more resemble our Western religions than the official Chinese “three teachings” (Confucianism, Buddhism, and Taoism). In his opinion, all our Western categories and notions related to “religions” appear inadequate to the Chinese religiosity, although the local Westernised elite tries to apply them. Among principal characteristic of the Chinese religiosity one can enumerate the absence of the division into sacred and profane, so fundamental to the Indo-Europeans and to the peoples of Mediterranean civilisations, and to their very concept of religion. Therefore, in China “religion” cannot be defined as “the sphere of sacredness or related to sacredness”, and distinguished from the “profane”. Émile Durkheim’s concepts, inherited by Mircea Eliade, appear inadequate to the social realities where everything is sacred-and-profane, although in different degree, and everything could possess greater or smaller, invisible, but not „supernatural” „powers”. The author points out a particular heritage of the three Mediterranean monotheistic religions (Judaism, Christianity, and Islam) that shaped the Western notions of “religion”. Their common characteristics are outlined, such as a “community of believers”, temples as “sacred places”, “a sacred day of a seven-day week”, the struggle between forces of Good and of the Evil, particular status of “humans” as “God’s creatures”, and a particular relations between God and Man, the eternal truth of God’s words (that allows the distinction of “heretics” and “pagans”), the concept of “metaphysics”, of “spiritual beings”, of “supranatural”, and of transcendence, etc. In addition, these “religions” constituted a very noble sphere, and “priests” – a particular elite. The author indicates that in China religious affairs enjoyed much less respect, and each community was religious-and-profane. Their heads usually maintained relations with community’s protective spirits (considered its “particular members”!) and represented it vis-á-vis the “outside world” – social-and-spiritual. From the family to the state all structures were semi-religious, and all performed similar functions: administrative, managerial, religious, and educative. Therefore even today the separation of the state from the religious affairs and from moral education of the population – is truly difficult. The differences are even deeper. In the West believing in some revealed, sacred truths is essential, so orthodoxy is central for its religions. In East Asia, on the other hand, right practice is most essential, whereas various concepts were allowed or propagated, side by side. Therefore orthopraxy is central to its religiosity. Moreover, the followers of the monotheistic religions concentrate their attention on God, and they threat gods with a similar attention and respect, thus their worldview is theocentric. In Chinese religiosity the human beings were central, so the anthropocentric worldview predominated there. There were no “ontological gulfs” between man, God and other spiritual beings, and animals or objects. All “beings/objects” are matarial-and-spiritual/energetical, human beings are divided into numerous “ontological categories” – lower and higher. So they could reach higher forms of existence, including gods and god-type levels, or descend to “lower” forms (which not necessarily appear “lower” to the Chinese). So called “teachings” (jiao) indicate how humans could reach higher ontological forms, whereas other popular religious-type practices help them to obtain prosperity, longevity, and happiness. The Yin-Yang dualism was of complementary nature, nor antagonistic, as the struggle of Evil against God, forces of Darkness against Light. Therefor the concept of “mission” and of “holy struggle” were alien, instead the concept of harmony was presented as the main principle of the universe, and the idea of adapting to the natural order was promoted. The educated scholars and administrators constituted a Chinese elite, not noble warriors and clergy, as among the Indo-Europeans. However, some elementary Indo-European and Mediterranean influences could be detected in China, and their concepts become known to a certain degree through Buddhism, Manicheism and Islam. The Western religious systems are “closed”, i.e. the communities of believers are “closed”, the pantheons, truths, rites, temples, etc. all are “closed”, or “restricted”. On the other hand, in China all of them are “open”: a “worshiper” could at the morning study Confucian books, at the afternoon visit a Taoist temple, and for funerals of his grandma invite Buddhist monks, a Catholic priest and a rabbi, if he resides near by. He could erect a temple to any spirit he likes, even to a hero of a novel, and he could establish particular rites to him, and such cult could be diffused and eventually approved by the state. Even a living person could be worshipped and become a “tutelary spirit”. Almost each figure could be put on an altar at every temple, so they usually are syncretic. The “temples” are not “sacred”, but could serve to various social purposes. Everybody could enter every temple, every time he liked, and for various purposes, or do not enter any of them. There was no “clergy”, nor organised “churches”, etc. In addition to personified powers the Chinese acknowledged existence of innumerable invisible forces of the universe, belonging to its natural order. They could not be “worshipped”, but one had adapt one’s actions to them. It was the sphere of “pseudo-sciences”, like geomancy, astrology, the Yin-Yang and the Five Elements, fortune-telling, characteristics of time-space “sectors”, etc. Therefore there is no boundary between “religion” and civic or political life, hence “religion” could not be distinguished and separated there. The practices that resemble mostly our religion were disdained by the Chinese elite, and considered the “superstitions” of uneducated folk. Gu Hongmin (1857-1928) seems to be right indicating that this elite cultivated and propagated a kind of “religion of good-citizenship” that constituted the superior level of the Chinese “religiosity” but was “religious” in its approach, not in its contents or forms. Hence the Chinese religiosity is a very complex phenomenon, and the Western categories often obscure its nature and its multiple functions.

Opis:
Mycorrhizal fungi greatly enhanced the ability of plants to take up phosphorus and other nutrients those are relatively immobile and exist in low concentration in the soil solution. Fungi can be important in the uptake of other nutrients by the host plant. Mycorrhizae establish symbiotic relationships with plants and play an essential role in plant growth, disease protection, and overall soil quality. Of the seven types of mycorrhizae described in current scientific literature (arbuscular, ecto, ectendo, arbutoid, monotropoid, ericoid and orchidaceous mycorrhizae), the arbuscular and ectomycorrhizae are the most abundant and widespread. This chapter presents an overview of current knowledge of mycorrhizal interactions, processes, and potential benefits to society. The molecular basis of nutrient exchange between arbuscular mycorrhizal (AM) fungi and host plants is presented; the role of AM fungi in disease protection, alleviation of heavy metal stress and increasing grain production. Most land plants form associations with mycorrhizal fungi. Mycorrhizas are mutualistic associations between fungi and plant roots. They are described as symbiotic because the fungus receives photo synthetically derived carbon compounds and the plant has increased access to mineral nutrients and sometimes water.

Opis:
Root, stem and leaf development are all negatively influenced by drought stress which causes losses in yield and quality and ultimately serious economic losses for growers. This study was conducted to see the efficiency of potassium treatments in reducing the negative effects drought stress on yield and quality of beans largely consumed in Turkey. Zulbiye bean cultivar sensitive to drought stress and V71 bean genotype which was also previously identified as sensitive to drought stress were used as the plant materials of the experiments. Bean seeds were sown in 2 L pots filled with perlite. Different potassium (K) doses of 0 (control) ppm K, 500 ppm K, 100 ppm K and 2000 ppm K were applied to seed sown pots. Seeding was performed as to have two plants in each pot and experiments were conducted in randomized blocks factorial experimental design with 4 replications with 4 pots in each replication. Pots were irrigated with Hoagland nutrient solution throughout the experiments. Irrigations were totally terminated on 20th day for drought stress plants. Following 15 days of stress conditions, plant height, fresh weight, root collar diameter, number of leaves and leaf size, leaf relative contents and membrane damage index values were determined. It was concluded based on present findings that 2000 ppm K treatment was more efficient in reducing the negative effects of drought stress on investigated growth and development parameters.

Opis:
Optimal nutrition of sugar beets at critical growth stages is one of the crucial factors for the achievement of their highest yield potential. In the present study, it was presumed that reduced systems of sugar beet cultivation had no effect on the plants’ nutritional status at critical growth stages, on their yield or technological quality. In 2012-2013, two series of one-factorial field experiments with different beet crop husbandry were carried out in order to verify this hypothesis. The cultivation systems of sugar beet crops differed in the postharvest cultivation technology, mulch types and seedbed tillage. Conservation tillage systems were compared with the control treatment, which represented the conventional cultivation system with an application of manure and 35 cm deep autumn ploughing. The plant nutritional status assessment was carried out at two dates corresponding to the following growth stages: BBCH 16/17 (6-8 fully unfolded true leaves) and BBCH 39/40 (row closing). Regardless of the methods of tillage or the year of observation, the results showed that the plants at BBCH16/17 stage were well-nourished with macroelements but malnourished with microelements, mainly iron and zinc. The microelement deficiency in the plants was a result of adjusted soil reaction, which varied from slightly acidic to neutral. At the BBCH 39/40 stage, there was a decreasing trend in the content of leaf macronutrients in the no-tillage systems treatments compared to the conventional tillage with the ploughing depth to 35 cm and manure application. The reduced tillage systems in sugar beet cultivation did not result in either a yield decrease or a worse technological quality of roots. The experimental factor had no significant effect on the content of molassegenic compounds in beet roots. A decreasing trend was observed in the content of α-amino nitrogen and potassium when compared to the traditional cultivation system. The study showed that the choice of a cultivation technology is of secondary importance as long as the plant grows in optimal conditions resulting from an appropriate site selection.

Currently there is a wide range of different kinds of power tools on the market. In the case of impact drills the major threat to the user’s health are vibration and acoustic impacts. Knowing that the actual drilling conditions may vary significantly from standardized conditions. It is important to determine the actual maximum level of dangerous factors present during drilling. Furthermore, it is also very important to link that factors to the conditions in which they occur. Among many factors affecting the level of vibration of an impact drill, change of the working position, the length of the drill bit and the diameter of the drill bit were verified in this paper. Verification was based on a comparison of vector-weighted mean values of acceleration of vibrations RMS a registered on the handles of the impact drill, while drilling in concrete, under different working conditions.

The article contains reflections on “a different theory of literature”. By emphasising the impossibility of maintaining a vision of theory as a history of courses, research methods, academic disciplines and other ‘isms’ and ‘turns’, the author suggests replacing this with ‘a different theory’. This is ‘different’ in that it is written as dramatography; different because it does not comprise uniform subject matter, but various interwoven discourses; different because it consolidates individual experiences and frequently develops away from one concept. This issue of “Przestrzenie Teorii” deals with theory emerging from art, theory rooted in and rooting itself in art.

Opis:
The objective of this study was to analyze the effect of different tillage systems on the yield, quality and mineral composition of grain of durum wheat. Three tillage systems were compared in the experiment: 1) conventional (CT), 2) reduced (RT) and 3) herbicide (HT). In the CT system, shallow ploughing and harrowing were performed after the harvest of the previous crop and late autumn ploughing was carried out before winter. In the RT system, double cultivation was performed instead of ploughing, whereas in the HT system the cultivation treatments were replaced by a herbicide containing a.s. glyphosate. In the springtime, a tillage set consisting of a cultivator, string roller and harrow was applied on all plots. Yields of wheat were higher in the years with high precipitation (years 2013-2014) than in the year with low precipitation (2015), as well as in the HT system than in the CT and RT systems. The content of total protein and wet gluten, as well as grain volume weight and grain uniformity were affected more by the study years than by the tillage systems. High sums of precipitation facilitated the accumulation of phytate-P and copper (Cu) in the grain, whereas the precipitation defict increased the content of potassium (K) and magnesium (Mg) in grain. The CT system contributed to the accumulation of phytate-P and iron, the RT system favoured the accumulation of calcium and manganese, whereas the HT system stimulated the accumulation of phosphorus, potassium, magnesium and copper in durum wheat grain.
