Opis:
Hybrid war represents one of the most used terms in the area of military and security affairs in the last years, especially after the outbreak of conflict in Ukraine. It appears still more frequently not only in scientific or specialized military or security publications, studies or articles, but also in various journals, news, reports or debates out of military or security community. It might be seemed that it is a new term or even new type of conflict, but it is not. Hybrid war is really no new phenomenon, it is known for many years; however, after the Russian annexation of Crimea, it is much more popular and used. On the other hand, the majority of wider public do not know what the mentioned term exactly represents, and that is the reason why an author of the article deals with this topic and, through gained results of the research, tries to explain the essence of examined problem.

Opis:
The beginning of the 21st century is characterized by a deep crisis of the national and international security system. For many factors caused by the intensification of military-political conflicts of a new type, the term “hybrid war” is now used. A feature of these conflicts is, in the first place, the use by the opponents of a wide scale of non-military means of influence: economic, informational, environmental, social, political and others. It is important here to justify the importance of the transformation of the state system of civil protection, which is being developed under the influence of contemporary military and political conflicts. The problem of military-political rivalry, by defining the content of the term “military-political conflict”, leads to a confrontation of political entities both within the state and at the state level, as well as between states, aimed at achieving their own political interests using various means and ways of influencing the political, military, economic, social and information spheres. The purpose of this speech is to present the mechanisms of solving all existing problems related to the functioning of society and to present the forms and features of contemporary hybrid conflicts.

Opis:
This article presents the advantages of hybrid approach to the support decision making by analyzing three areas of business decision problems, solved by combination of well-known algorithms into the new hybrid constructions: cascade optimization hybrid, parallel classification hybrid and hybrid multicomponent attribute selection. Each of them solved a different problem: the cascade optimization hybrid allowed for finding an extreme of a composite objective function, the parallel classification hybrid was used to choose a proper class through voting, the multicomponent attribute selection robustly chose significant decision variables. A hybrid approach to the problem of supporting the decision making processes is more effective than using each of the component methods alone, even for the sophisticated ones. A combination of several methods with different characteristics and performance makes it possible to take advantages of their strong sides and simultaneously eliminate the weak ones, resulting in a better computational support of decision making.

Opis:
Artykuł podejmuje kwestię percepcji pojęcia przedsiębiorstwa hybrydowego wśród praktyków oraz wpływu praktyk hybrydowych na funkcjonowanie przedsiębiorstw. W tekście zestawiono pojęcie przedsiębiorstwa hybrydowego występujące w literaturze przedmiotu z wynikami badań pilotażowych przeprowadzonych wśród kadry menedżerskiej średniego szczebla. Wyniki badań wskazują na relatywnie słabą znajomość pojęcia przedsiębiorstwa hybrydowego wśród praktyków oraz wyraźne jego utożsamianie ze sposobem organizacji pracy pracowników. Badani menedżerowie w większości hybrydowość działania traktowali jako zjawisko zewnętrznie wymuszone, a nie samodzielną wewnętrzną decyzję. Docelowo nie byli zainteresowani rozszerzaniem zakresu działań hybrydowych, a raczej utrzymaniem aktualnego stanu, mimo że jako główną zaletę wprowadzenia rozwiązań hybrydowych wskazali możliwość redukcji kosztów oraz możliwości lepszego wykorzystania potencjału.
The article focuses on how the practitioners perceive the term ‘hybrid enterprise’ and on the impact of hybrid practices on organizational performance. The text makes a broad overview of the semantic field and meanings associated with the term ‘hybrid enterprise’ in subject-matter literature and discusses the results of questionnaire-based surveys conducted on a sample of 31 people. These results confirm the initial assumptions about the difficulty in unambiguously defining the concept of a hybrid enterprise and the fact that practitioners are relatively little familiar with the term.

Opis:
Despite the fact that the hybrid wars were conducted for centuries, the annexation of the Crimea and the involvement of the Russian Federation in the conflict in the Ukraine calls new discussions over its essence. Evaluation of the theory and practice of the activities carried out by FR indicates that we are dealing with the new generation of war. However, it is not in contradiction with the "Clausewitzian paradigm" of conducting armed struggle, which says that war is merely a continuation of politics by other means. The hybrid actions refer precisely to these measures, whereas the rules of warfare, its nature and objectives are still the same.

The media environment is an extremely variable universe where every now and again we can observe the emergence of new phenomena. Many of those form through blending of often rather different and distant areas. As a result, there emerge hybrid forms, which are not entirely established or completely defined. This article is focussed on those kinds of mixed types based on media entertainment, e.g. infotainment, edutainment, politainment, politicotainment, docutainment etc., which can be observed in the means of mass communication. The goal of the study was to define their essence, their distinctive features, and to indicate the place of those hybrid forms within the media discourses being carried on today.

Opis:
16-chromosome forms of red clover (2n=14+2) were crossed to six Trifolium species with the chromosome number 2n=16. Hybrid plants were derived from the cross of a stable 16-chromosome red clover T. pratense with T. diffusum (2n=16). No seeds were obtained from reciprocal crosses. F₁ hybrid plants were morphologically more similar to T. diffusum, whereas their other characters, e.g. flower number per head, were intermediate between the species crossed. All F₁ hybrids had the chromosome number 2n=16. Meiosis proceeded with large irregularities. The average number of bivalents per cell was 3.32, and that of univalents - 9.98. Univalents exhibited a high stickiness and frequently formed "end-to-end" configurations and chains consisting of about a dozen of so chromosomes. Bivalents were straight. Lagging chromosomes and chromosome bridges were observed during AI; lagging chromosomes were also found during AII. After an equalizing division, tetrads and different from them microspore polyads were formed. 16-chromosome hybrids were male- and female-sterile. No hybrids were obtained from the stable 16-chromosome red clover T. pratense (n=7 chromosomes) crossed to the selected clover species (T. apertum Bobr., T. alexandrinum L. and others) with n=8 chromosomes.

Opis:
Nowadays, transportation becomes a significant source, apart from factories and power plants, of air pollution. Therefore, due to legal restrictions on the emission of noxious gases, other power sources for vehicles are necessary. Some of these power sources allow replacement of the internal combustion engine completely, whereas the other ones only support the engine operation. Hence, a hybrid powertrain – alternative to the drivetrain equipped with an internal combustion engine only – is increasingly being used. The hybrid powertrain was mostly applied in cars and buses but recently it has been also used in railway vehicles such as locomotives and multiple units. The paper presents a shortened and brief overview of construction solutions of selected hybrid locomotives. A list of the applied hybrid drive systems as well as the basic data and properties are provided. The most important variants of vehicles are compared. The presented material allows identification of the development trends in the considered area. The hybrid locomotive usually uses an onboard rechargeable energy storage system, placed between the power source and the traction transmission system connected to the wheelsets. Modification of a classic diesel-electric locomotives is a relatively simple procedure since they have all the components of a series hybrid transmission except the storage battery. Therefore, the existing and operated diesel-electric locomotives can be modified to increase their efficiency and reduce operating costs and emissions.

Opis:
In this article, hybrid warfare challenges and their impact on the evolution of warfare in the new dynamic security environment are analysed. The aim of the research was to identify hybrid threats, explore the complexity of the hybrid conflict that involves professional Armed Forces and irregular (paramilitary) forces. The research has been conducted through two case studies of hybrid warfare: the Israeli - Lebanese conflict in 2006 and the Lebanese militia organisation Hezbollah as a prototype of hybrid opponents; and the contemporary hybrid conflict in Ukraine through the Russian paradigm of hybrid warfare. The conducted research showed that the decisive role that influenced the outcome of the conflict belonged either to rapidness or inertia in of the making of political decisions. The research results showed further that revision of the existing strategic and doctrinal documents are required, as well as reorganisation of the national security system (and the Armed Forces as part of it), without which they will not be able to deal successfully with the dynamic nature of future conflict and complexity of threats (“synergy of threats”). The political decision is the most essential parameter for sizing military organisation. The rapidity of response in the event of emergencies (especially outside the national territory) also depends on the promptness of political decisions in order to activate the Armed Forces.

Main goal of article was design, develop and control of Stop&Go system in Mild Hybrid Drive using supercondensator and starter with permanent magnets. Many researches and tests were done to determine real and then representative cycles of drive in Silesian agglomeration in Gliwice and Zabrze. Road researches enabled carrying out analysis of fluidity of traffic in cities and setting a percentage shares of movement micro stages (selected accelerations, driving with constant speed, braking, stopover). Researches of usefulness of supercondensators' system as an energy source in process of starting an internal combustion engine were done. Usage of supercondensators as an energy source of starting led to improvement of economic indicators of the Stop & Go system. Supercondensator has a 1000 times bigger durability than PbPbO2 battery with around 40 times smaller mass. Researchers of real characteristics of the car Fiat Palio Weekend 1,2 8V were done for calculations of traditional characteristics The Stop & Go system was designed and produced for this vehicle A starter, which will have NeFeB magnets built in stator instead of induction winding, was designed. A modernization of the starter is necessary because of different type of working - frequent starting of the internal combustion engine. A project of the Stop & Go system was carried out in the Fiat Palio car a project of the Stop & Go system for Mild Hybrid drive and verification of correctness of working has been carried out in the Fiat Palio car.

Aim. The aim of is article is to discuss how summer schools can be approached as instances of hybrid education and how this can help to address the complex needs of their participants living in a culturally and technologically intertwined world. Methodology. This paper analyses the theoretical framework of hybrid education, its manifestations in summer schools and since it needs contextualisation, how it works in a specific case of Baltic Summer University organised by Vytautas Magnus University (Kaunas, Lithuania). Research and conclusion. To reach their target audience, summer schools combine academic content, and the elements of business and entertainment. This results in a separate mode of education with new possibilities and scope, however poses a paradox: while the adoption of business and entertainment practices puts summer schools somewhat outside the realm of the traditional university practices, it makes higher education more approachable and able to react to the fast-changing reality. Baltic Summer University fits the pattern established and as such, could benefit from a more active engagement of this theoretical approach and the opportunities it offers.   Originality. While summer schools are not a particularly new phenomenon, recently this field has witnessed a great expansion in both the supply of programmes and interest from students. The nature of these programmes and sudden interest in them remains under the radar of more extensive in-depth studies, which would actually help to harness its full potential.

As electric drives slowly replace passenger cars and light special vehicles, electric drives in the heavy-duty road sector have started to emerge. As for off-road vehicles, there is some effort to reduce the amount of fossil fuel used. In this study, the series hybrid application for a heavy-duty tractor is investigated. Work conditions are described using modified worldwide transient vehicle cycle to evaluate the efficiency of an energy management system applied, as well as the overall vehicle performance and efficiency. As a result, in some test scenarios, smaller-than-expected energy outputs were identified and new ways to improve energy management were found.

Opis:
W artykule opisano początkowy etap konstrukcji napędu hybrydowego samochodu o strukturze Mild Hybryd. System ten pozwoli m.in. na automatyczne wyłączanie silnika spalinowego podczas postoju (w korku, na czerwonym świetle) a następnie ponowne szybkie załączenie. Zaprezentowano wybrane wyniki badań procentowych udziałów podstawowych faz cykli ruchu jazd testowych miastach śląska. Pomiary przeprowadzano na trasie Gliwice - Zabrze, w Zabrzu oraz Gliwicach. Przedstawiono badania superkondensatora w procesie rozruchu silnika spalinowego.
The paper describes initial stages of Mild Hybrid drive system design. This type of drive uses a traditional electric unit consisting of a battery, a starter and an alternator. This system, appropriately adapted, for instance by increasing its overall rated power and supplementing it with novel energy control procedures, can operate in a manner similar to hybrid car drives. Mild Hybrid system utilises standard components used in cars - i.e. starter and alternator. A supercapacitor will be introduced as a new component. Its role is to operate as energy accumulator for IC engine start-ups. A traditional car battery will also assume a new function, that of heating IC engine. Automobile Stop & Go System makes it possible to switch off the IC engine automatically when a vehicle stops (e.g. at red light or in traffic hold-ups) and then to switch it on quickly again. This results in decreasing the fuel consumption and carbon dioxide emission, particularly in towns. Within the framework of this study, there were taken the road measurements whose aim was to determine the real driving cycles. The results of supercapacitor performance during IC engine start-ups are presented in the paper. Several tens of IC engines start-ups were conducted, with the starter supplied from a traditional standard lead-acid battery (Centra Futura 055 290, C20=55Ah); next, similar tests were run using the supercapacitor (MAXWELL BPAK 15V 58F). The energy consumption at start-up and the start-up time were calculated.

Opis:
Published for the first time in 1940 the André Breton’s Anthology of black humor inaugurates the great season of surrealist anthologies, which will last until late 60s. The use of the traditional form of the modern anthology by the Surrealists, does not involve into a complete acceptance of its rules, already codified since the end of the 19th century, but rather a deformation of its textual structure and of its objectives, producing a literary genre with particular characteristics. The surrealist anthology, such as those realized by André Breton, Paul Éluard, Louis Aragon and Benjamin Péret, represent an hybrid literary object with structural elements in common with the dictionary, the glossary, the anthology and the catalogue. The surrealist literary collections represent both a different approach to the history of literature and an expression of surrealist poetics.

Possibilities of combustion engine – electric machine assembly run irregularity improvement have been presented in the following paper. Such system is the basic one in numerous hybrid car available on the market but the concept of using an electrical machine for reduction of rotational speed changeability amplitude in reciprocating machines could be utilized in any drive unit, especially in ship propulsion. This idea consists in generation of braking torque by the electric machine whenever the coupling shaft increases its rotational speed and vice versa, driving the system when the momentary speed is lower than the average speed within a complete shaft rotation.

Opis:
This article is a continuation of our promenade along the winding roads of identity, equality, nameability and completeness. We continue looking for a place where all these concepts converge. We assume that identity is a binary relation between objects while equality is a symbolic relation between terms. Identity plays a central role in logic and we have looked at it from two different points of view. In one case, identity is a notion which has to be defined and, in the other case, identity is a notion used to define other logical concepts. In our previous paper, [16], we investigated whether identity can be introduced by definition arriving to the conclusion that only in full higher-order logic with standard semantics a reliable definition of identity is possible. In the present study we have moved to modal logic and realized that here we can distinguish in the formal language between two different equality symbols, the first one shall be interpreted as extensional genuine identity and only applies for objects, the second one applies for non rigid terms and has the characteristic of synonymy. We have also analyzed the hybrid modal logic where we can introduce rigid terms by definition and can express that two worlds are identical by using the nominals and the @ operator. We finish our paper in the kingdom of identity where the only primitives are lambda and equality. Here we show how other logical concepts can be defined in terms of the identity relation. We have found at the end of our walk a possible point of convergence in the logic Equational Hybrid Propositional Type Theory (EHPTT), [14] and [15].

Opis:
Barley doubled haploids (DH) derived from first and second cycle hybrids were investigated in field experiments. Parental lines designed for the second cycle hybrids were three doubled haploids from the first cycle hybrids, which were observed to have the highest grain yield. Yield structure characters, crude protein content and protein fractions were analysed. Phenotypic and genetic variability and the frequency of transgression in the studied populations were calculated. For the studied traits additive, [d], and epistatic (additive x additive), [i], effects as well as coefficient of gene dispersion were estimated. It was found that the phenotypic and genetic variability of DH populations derived from second cycle hybrids was higher than that of the original population for all the studied traits except grain yield. A greater proportion of transgressive lines than in the original population was also observed in populations from second cycle hybrids. Only one DH line exceeding the high yielding parent was found among 141 lines under study. The relationship between the frequency of transgressions and gene dispersion was recorded: the greatest number of transgressive lines occurred in those traits for which the dispersion was observed.

Opis:
For a few years, the sales of motor vehicles with hybrid drive systems (referred to as “hybrid vehicles” or “HVs”) have been rapidly growing. However, there is a lack of information about the intensity of operation of vehicles classified in this category, which is completely new. A calculation procedure has been presented that enabled evaluation of the HV mileage growth rate. An analysis of this rate provides grounds for forecasting the changes that are likely to take place in the fleet of motor vehicles, such as the progress in the process of replacement of conventional vehicles with vehicles with alternative drive systems, and this may be a basis for predicting the reduction in fuel consumption and exhaust emissions. Models of the HV mileage growth process have been defined for three different countries. They indicate high mileage growth rates in the initial period of vehicle operation, e.g. until the fourth year of operation of the Auris H cars. The highest mileage growth rates in this period were observed in the Netherlands and Poland. In Germany, this rate was lower by 41%. Significant differences in the intensity of vehicle operation have been observed between the behaviour of HV owners in the countries under analysis. A considerable drop in the annual HV mileage as early as in the fifth and sixth year of vehicle operation is an alarming signal.

Opis:
The basic premise of the paper is that the study of formal and informal processes has moved beyond the formality-informality debate. Forms which may be termed as hybrid formalities and hybrid informalities are more and more often encountered in the literature. However, these hybrid types are pretty much under construction, and they occur in a rather disparate manner. So that, there is need of a systematic approach which would conceptualize them within a broader typology. The paper advances such a typology of hybrid formalities and informalities. For the sake of conceptual unity, these are drafted in the same theoretical framework-the structuralist perspective on informal economy. Eventually, the systematization of this typology of hybrids leads to the formulation of some general findings about the manner in which sociologists relate to formality and informality in general.

Opis:
Gene pool variation of twenty varieties and breeding clones of Fragaria × ananassa, nine varieties and breeding lines of Fragaria vesca, and one new interspecific hybrid designated Fragaria × anavesca was analysed with three DNA marker systems. ISSR reactions with four primers produced 45 polymorphic markers. Similarly, RAPD analyses with three primers produced 26 markers and SSR method with three primer pairs revealed 28 different alleles. The total number of 99 polymorphic markers allowed distinguishing clearly a group of F. × ananassa genotypes from that of F. vesca genotypes with F. × anavesca in between of these two. RAPD markers proved to be more informative than ISSRs as 3 of 26 were specific to F. × ananassa only and one exclusively to F. vesca and F. × anavesca. Thus, the presumed hybrid nature of F. × anavesca was effectively confirmed by RAPD markers. Especially important was the 1100bp long PCR product of the B104 primer present in all F. vesca genotypes as well as in F. × anavesca but absent in F. × ananassa. Presence of F. vesca DNA in the hybrid F. × anavesca was additionally corroborated by the 223bp product of the UDF017 primer pair and the 185bp-long band generated with the UDF006 primer pair.
Analizowano zmienność w puli genów dwudziestu odmian i klonów hodowlanych Fragaria × ananassa, dziewięciu odmian i linii hodowlanych Fragaria vesca i nowego prawdopodobnego mieszańca międzygatunkowego nazwanego Fragaria × anavesca przy zastosowaniu trzech systemów markerów DNA. Cztery startery ISSR wygenerowały 45 markerów polimorficznych. Trzy startery RAPD dały 26 markerów, natomiast trzy startery SSR – 28 markerów polimorficznych. 99 uzyskanych markerów polimorficznych pozwoliło na jednoznaczne odróżnienie grupy genotypów należących do gatunku F. × ananassa od grupy genotypów należących do gatunku F. vesca z mieszańcem F. × anavesca sytuującym się pomiędzy nimi. Markery RAPD okazały się lepszym źródłem informacji niż ISSR, ponieważ 3 spośród 26 były specyficzne tylko dla F. × ananassa, a jeden wyłącznie dla F. vesca i F. × anavesca. W ten sposób, za pomocą markerów RAPD, potwierdzona została przypuszczalna wcześniej mieszańcowość F. × anavesca. Szczególnie istotny okazał się produkt reakcji PCR ze starterem B104 o długości 1100pz obecny we wszystkich genotypach F. vesca oraz F. × anavesca, a niewystępujący u F. × ananassa. Obecność DNA pochodzącego z F. vesca w mieszańcu F. × anavesca została dodatkowo potwierdzona poprzez produkt pary starterów UDF017 o długości 223pz i produkt pary starterów UDF006 o długości 185pz.

After duplicating the chromosome number by colchicine in sterile F₁ 16-chromosome hybrid T. pratense × T. diffusum some partially fertile plants with 32 chromosomes were found. Male fertility (viability of pollen grain) was from 69.3% to 86.2% (on average 81.8%), whereas female fertility estimated as seed setting after cross- and self-pollination was 21.8% and 6.9%, respectively. Male and female fertility as well as somatic chromosome number were examined in the F₂-F₄ generations. Selection for female fertility resulted in increasing seed setting in the first two generations (F₂ and F₃) and in decreasing it in F₄ generation. An average seed setting in the F₂-F₄ generations after cross-pollination amounted to 22.2%, 43.6% and 12.9%, respectively; after self-pollination it was 25.2%, 27.6% and 1.9%. In the F₂ generation all the plants had 2n=32 chromosomes. In the next generations there appeared aneuploids, among which 30-chromosome individuals were predominant.

Opis:
Recent years have brought significant progress in the field of hybrid vehicles. Today, almost all major manufacturers offer this type of cars for their clients. Hybrid drives have lower fuel consumption and less emission of toxic gases. These benefits have led to the rapid popularization of hybrid cars on the global market. The growing demand for economical vehicles leads to increased work of engineers on new improvements. The biggest drawback of such drives is their high cost of purchasing. The result is lack of small urban car with such a powertrain. Following article describes the prototype of hybrid powertrain designed for small car with diesel engine. Vehicle design is based on the construction of Fiat Panda. The project includes construction of the prototype vehicle with eAWD powertrain. Prototype vehicle will be used for research into finding the optimum powertrain control algorithms. Test results will determine possible fuel savings and economical benefits of using hybrid cars in urban driving cycle. Research results will be compared with the results of simulations carried out Matlab/Simulink program. This comparison will confirm the correctness of simulation algorithms that can be used in the process of optimizing the drive control program. Research results confirm the correctness of simulation algorithms that can be used in the process of optimizing the drive control program.

This paper shows the results of analyzing the effectiveness and efficiency of a hybrid approach against a variety of optimization problems. An application with a serial-optimization structure, consisting of several methods with different characteristics, is presented. In order to evaluate the initial effectiveness of the hybrid optimization method, a number of test tasks, represented by complex functions with many variables, were examined. Additionally, a real-life case, determining an optimal product variety in a supermarket environment, regarding the highest rate of return for given conditions and limitations, is presented as an instance of the practical use of a hybrid algorithm. The research shows that the results achieved by the hybrid- -optimization method are highly satisfactory, both in terms of efficiency as well as effectiveness.

Ensuring security in an increasingly complex and uncertain world requires states to address a number of challenges. eThse include the need to remain cooperative in the international space and the need to pursue their strategic objectives. Oeftn these are followed up by intentional or unintentional threats that can eefctively destabilise not only a single state, but also an entire region. eThir emergence may be the result of a lack of resilience against hostile actions by state or non-state actors who, in order to achieve their objectives, undertake, among other things, hybrid activities. However, the terms 'state resilience' and 'hybrid activities' are insuficiently precisely formulated in the literature and described in a conceptual rather than a definitional manner. Both national and NATO documents lack universally accepted definitions of these terms. eTh aim of this article is to present the concept of building state resilience to hybrid activities.
Zapewnienie bezpieczeństwa w coraz bardziej złożonym i niepewnym świecie wymaga od państw sprostania wielu wyzwaniom. Należą do nich konieczność utrzymania kooperatywnego charakteru w przestrzeni międzynarodowej oraz potrzeba realizacji swoich celów strategicznych. Często następstwem takich działań są intencjonalne lub nieintencjonalne zagrożenia, które mogą skutecznie zdestabilizować nie tylko pojedyncze państwo, lecz także cały region. Ich pojawienie się może być efektem braku odporności na wrogie działania podmiotów państwowych lub niepaństwowych, które dla osiągnięcia swoich celów podejmują m.in. działania hybrydowe. Terminy „odporność państwa” i „działania hybrydowe” w literaturze przedmiotu są jednak niewystarczająco jasne i opisywane w sposób bardziej konceptualny niż definicyjny. W dokumentach zarówno narodowych, jak i NATO brakuje powszechnie uznanych definicji tych pojęć. Celem artykułu jest przedstawienie koncepcji budowania odporności państwa na działania hybrydowe.

Opis:
Zapewnienie bezpieczeństwa w coraz bardziej złożonym i niepewnym świecie wymaga od państw sprostania wielu wyzwaniom. Należą do nich konieczność utrzymania kooperatywnego charakteru w przestrzeni międzynarodowej oraz potrzeba realizacji swoich celów strategicznych. Często następstwem takich działań są intencjonalne lub nieintencjonalne zagrożenia, które mogą skutecznie zdestabilizować nie tylko pojedyncze państwo, lecz także cały region. Ich pojawienie się może być efektem braku odporności na wrogie działania podmiotów państwowych lub niepaństwowych, które dla osiągnięcia swoich celów podejmują m.in. działania hybrydowe. Terminy „odporność państwa” i „działania hybrydowe” w literaturze przedmiotu są jednak niewystarczająco jasne i opisywane w sposób bardziej konceptualny niż definicyjny. W dokumentach zarówno narodowych, jak i NATO brakuje powszechnie uznanych definicji tych pojęć. Celem artykułu jest przedstawienie koncepcji budowania odporności państwa na działania hybrydowe.
Ensuring security in an increasingly complex and uncertain world requires states to address a number of challenges. These include the need to remain cooperative in the international space and the need to pursue their strategic objectives. Often these are followed up by intentional or unintentional threats that can effectively destabilise not only a single state, but also an entire region. Their emergence may be the result of a lack of resilience against hostile actions by state or non-state actors who, in order to achieve their objectives, undertake, among other things, hybrid activities. However, the terms ‘state resilience’ and ‘hybrid activities’ are insufficiently precisely formulated in the literature and described in a conceptual rather than a definitional manner. Both national and NATO documents lack universally accepted definitions of these terms. The aim of this article is to present the concept of building state resilience to hybrid activities.

Opis:
The paper presents a study on the content of Ca, Mg, K, Mn, Zn, Cu, and Fe in kernels (F5 generation) of winter triticale produced by crossbreeding three maternal with two paternal forms. As maternal forms, two strains were used, IGS 5101, FDT 975, as well as cultivar Alzo. The paternal components consisted of strains LAD 122 and F 8063. Morphologically established hybrid strains were selected at the Institute of Genetics, Plant Breeding and Biotechnology of the University of Life Sciences in Lublin. The component selection for crossbreeding was performed to achieve hybrids with great yield-forming potential and to improve the resistance to grain sprouting. Minerals were determined by the atomic absorption spectrometry (AAS) method. The results revealed differentiation in amounts of the analysed mineral components in hybrids depending on genotypes of the parental forms. Hybrid strains were usually characterized by a lower ash content in kernels than the parental forms. Among all the hybrids, strain IGS 5101 x F 8063 was distinguishable by its higher content of K, Ca, Mn, and Fe in grain versus both parental forms. It also excelled exceeded the other hybrids in respect of Ca, K and Mn. Tests on the mineral components in hybrid triticale strains indicate that it is possible to shape their levels through an appropriate selection of parental forms and selection during breeding work on X Triticosecale Wittmack genus to achieve cultivars of improved nutritional value.
W pracy badano zawartość Ca, Mg, K, Mn, Zn, Cu, Fe w ziarnie (pokolenie F5) pszenżyta ozimego otrzymanego w wyniku krzyżowania trzech form matecznych z dwoma ojcowskimi. Jako formy mateczne użyto: 2 rody IGS 5101, FDT 975 i odmianę Alzo. Formami ojcowskimi były rody LAD 122 i F 8063. Rody mieszańcowe ustalone morfologicznie wyselekcjonowano w Instytucie Genetyki, Hodowli Roślin i Biotechnologii Uniwersytetu Przyrodniczego w Lublinie. Dobór komponentów do krzyżowania prowadzono w celu uzyskania mieszańców o dużym potencjale cech plonotwórczych oraz poprawienia odporności na porastanie ziarna. Zawartość składników mineralnych analizowano metodą absorpcyjnej spektrometrii atomowej (AAS). Wyniki badań wykazały zróżnicowanie poziomu badanych składników mineralnych w mieszańcach zależnie od genotypów form rodzicielskich. Rody mieszańcowe wykazywały zwykle niższą popiołowość ziarniaków w porównaniu z formami rodzicielskimi. Z badanych mieszańców wyróżniał się ród IGS 5101 x F 8063, w którego ziarnie stwierdzono wyższą zawartość K, Ca, Zn, Mn i Fe w odniesieniu do obu form rodzicielskich oraz Ca, K i Zn w porównaniu z pozostałymi rodami mieszańcowymi. Badania zawartości składników mineralnych w mieszańcowych rodach pszenżyta wskazują na możliwość kształtowania ich poziomu przez odpowiedni dobór komponentów rodzicielskich i selekcję w pracach hodowlanych w obrębie rodzaju X Triticosecale Wittmack dla uzyskania odmian o wyższej wartości żywieniowej.

Opis:
Niniejszy tekst stanowi pierwszą część rozważań na temat cyborgizacji człowieka w kontekście zarówno teorii współczesnych, jak i pierwotnych badań nad tym zjawiskiem. W zależności od przyjętej, ewoluującej na przestrzeni lat definicji, w kontekście cyborgizacji człowieka cyborgiem można nazwać osobę, której ciało zostało na stałe zintegrowane z maszyną lub dowolnym tworem technologicznym, lub osobę, która korzysta z osiągnięć technologii, ale jej ciało nie jest połączone na stałe z maszyną, komputerem lub każdym innym sztucznym wytworem technicznym. Do pierwszej kategorii zalicza się więc np. ludzi funkcjonujących z wszczepionym rozrusznikiem serca czy tych posiadających sztuczne protezy kończyn. W drugą kategorię wpisują się osoby, których codzienna aktywność wspierana jest technologią, ale nie zostały wprowadzone na stałe do ich organizmów sztuczne, technologiczne elementy. W dzisiejszych czasach stechnicyzowanej kultury, w społeczeństwie informacyjnym, praktycznie każdy z nas spełnia te kryteria. Zgodnie z teorią rozszerzoną każdy z nas jest więc cyborgiem. W tym artykule zostanie przedstawiona geneza pojęcia cyborga oraz tematyka związana z funkcjonowaniem we współczesnym świecie cyborga wpisującego się w pierwszą kategorię. Przedstawione zostaną przypadki ludzi-maszyn i zasygnalizowane problemy etyczno-prawne związane z funkcjonowaniem takich osób w społeczeństwie.
This text is the first essay on human cyborgization in the context of contemporary theories and original research on this phenomenon. Depending on one’s chosen definition, which have evolved over the years, a cyborg can be called a person whose body has been permanently joined with a machine or any technological creation or a person who uses the achievements of technology but whose body is not permanently connected with a machine, computer, or any other artificial technological product. Thus, the first category includes, for example, people living with a pacemaker implant or those with artificial limbs. The second category includes people whose daily activity is supported by technology, but artificial technological elements have not been permanently fixed to their bodies. In today’s technological culture, in the information society, practically all of us meet these criteria. According to the extended theory, each of us is a cyborg. This article presents the genesis of the term cyborg and issues related to cyborgs of the first type functioning in the modern world. Cases of people-machines are presented and ethical and legal problems connected with such people functioning in society are discussed.

This paper deals with the concept of political topology in the light of geopolitics and hybrid warfare. Traditional geopolitics can be regarded as a point of departure for the search for better tools for political decision making. Comparison and confrontation of different, theoretical and practical, concepts of hybrid warfare can be heuristically inspiring and lead to a compact system of politically relevant knowledge – to political topology.

Opis:
Nowadays, aluminum-based composites have been produced by pure alumina (Al2O3) or pure graphene nanoplatelets (GNPs) in aluminum matrix because of the high compressive strength of alumina and the solid lubricant properties of graphene. However, there are no studies on the influence of both alumina and graphene reinforced aluminum composites. In this study, Al-Al2O3 and Al-Al2O3-GNPs composites were reinforced with pure alumina (between 0 and 30 wt.%), pure graphene (0, 0.1, 0.3, 0.5 wt.%), and their hybrid forms (Al2O3-GNPs) by the powder metallurgy method. This method involved ultrasonic dispensing, mixing, filtering, drying, pressing, and sintering processes. From the test results, the micro Vickers hardness of pure aluminum (28.2±1 HV) improved to 51.5±0.8 HV (Al-30Al2O3) and 63.1±1 HV (Al-30Al2O3-0.1GNPs). Similarly, the ultimate compressive strength (UCS) enhanced from 92.4±4 MPa (pure aluminum) to 165±4.5 MPa (Al-30Al2O3) and 188±5 MPa (Al-30Al2O3-0.1GNPs), respectively. In conclusion, the Vickers hardness and ultimate compressive strength of aluminum hybrid composites improved up to 0.1 wt.% graphene content. After 0.1 wt.% graphene content, these mechanical properties decreased because of the clumping of graphene nanoparticles.

Hybrid nanofillers of silica grafted with octakis({3-methacryloxypropyl}dimethylsiloxy) octasilsesquioxane were obtained by the method based on solvent evaporation with the use of both hydrated or emulsion spherical silica. Octakis({3-methacryloxypropyl}dimethylsiloxy) octasilsesquioxane was applied as a modifying agent and it was synthesized by employing the hydrosilylation reaction. The effectiveness of modification of the hybrid nanofillers obtained was verified using Fourier transform infrared spectroscopy and nuclear magnetic resonance (29Si and 13C CP MAS NMR). The products obtained were characterized by determination of their physicochemical properties and porous structure, including specific surface area, pore diameter and pore volume. Dispersion degree and particle size of the nanofillers was characterized by NIBS (Non-Invasive Back-scatter) method and laser diffraction technique, while their morphology by transmission electron microscopy.

Opis:
The contemporary demands in different branches of engineering require application of new multi-component materials and structural systems. Appropriately chosen joining technology can offer significant enhancement of structural system performance in terms of effectiveness, reliability, safety and other design criteria. The modern applications of complex joints are of great technological interest as they permit to combine and to enhance the individual effects of each kind of joint. This is of great importance for modern applications in different branches of engineering: aerospace, mechanical and civil. Therefore in this paper we will focus on the analysis of mechanical response of adhesive joint of aluminium strips reinforced by rivets. The aim of the paper is to investigate experimentally the mechanical behaviour of adhesive joint of aluminium strips reinforced by rivets for industrial applications in aerospace. The considered joint was subjected to uniaxial loading. The tests in this paper were performed for: • classical adhesive joint in order to investigate material parameters for numerical modelling of the hybrid joint • hybrid joining of the structural elements in order to investigate the reinforcement effect. The experiments with application of digital image ARAMIS system allowed for on-line monitoring of the deformation process of the considered joining elements. The particular distributions of displacement fields at the joint surface were estimated for any stage of loading process. Numerical modelling was performed for experimentally investigated specimens. The materials parameters, necessary for calculation, were estimated from experiments. FEA modelling was done with the help of ABAQUS code.

Opis:
In recent years, metal halide perovskites have gained significant attention due to their unique optical and electronic properties of semiconductor materials, which make them ideal for use in sustainable and energy-efficient devices. These devices include solar cells, lasers, and light-emitting diodes. Therefore, this review aims initially to provide an overview of the most important characteristics of metal halide perovskites, including their engineering development in various types, such as those based on lead or lead-free materials, like tin or germanium. Additionally, perovskites made from purely inorganic compounds like caesium bromide, chloride, or iodide, as well as hybrids mixed with organic compounds like formamidinium and methylammonium halides will be discussed. The goal is to improve their stability and efficiency. Secondly, some of the studies have proposed technologies combining electronic and mechanical characteristics of flexibility or rigidity as required, promoting their synthesis with different materials such as polymers (poly methyl methacrylate, polyvinylidene fluoride), biopolymers (starch, cyclodextrin, polylactic acid, and polylysines), among others. Finally, the subject of this work is to establish the main purpose of the research carried out so far, which is to develop simpler and more scalable processes at industrial level to achieve greater efficiency and duration in storage, exposure to visible light, critical environments, humid or high temperatures.
