From the AD 40s onwards a dense Roman military system was established along the Oude Rijn in the Netherlands. It has long been questioned why this system was established in a wetland area, and how it went on to become the northwest frontier or limes of the Roman Empire. In order to shed new light on this longstanding historical debate a detailed paleogeographical map was constructed. From the information assembled in this new map it can be concluded that this military system, which comprised a combination of forts and watchtowers, was established to watch over the river Rhine and its traffic, and to guard all waterways that gave access to the Rhine from the Germanic territories further north, and to and from the river Meuse further south to the delta.

It is clear that strategic and logistical motives determined the size and location of all of the forts and military installations in this fortified transport corridor. The construction of the series of forts from the early 40s AD onwards has been correlated with the conquest of Britain from AD 43 onwards, but the building project was initiated in the reign of Caligula (AD 37-41).
Xenophon de Halbattiker?
Authors: Huitink Luuk , Rood Tim
Published: June 2021

This article analyses Xenophon’s lexical choices in Anabasis. It examines ancient and modern critical approaches to his language: Xenophon has often been criticized for lapses from ‘pure’ Attic, but this notion of a ‘pure’ Attic should be regarded as a conservative response to the increasing variety of spoken Attic in the fourth century BC. Xenophon’s lexical choices reflect the influence both of this ‘Great Attic’ (which developed into koine Greek) and of the non-parochial historiographical tradition inaugurated by Thucydides.

The division in capita of Herodotus’ Histories goes back to the edition of Gottfried Jungermann of 1608. What were his model, motive, and method when undertaking this editorial task? The answers to the first two questions can be found in one of his prefaces (Ad candidum lectorem), the relevant section of which is here offered in a transcription and translation. The last question can only be tentatively answered by looking at the actual division itself, since he does not say anything about it, except that he wanted to keep together speeches.

Historical surface irrigation of pastures in the Dutch province of Noord-Brabant: visible traces of a failed experiment

In the second half of the 19th century, some major changes occurred in the water management of the eastern and southern provinces of the Netherlands. Unlike the low-lying western parts of the Netherlands which were characterised by polders and had a long history of formal water boards, the higher eastern and southern parts of the Netherlands were characterized by brook systems and sandy soils, and had no centralised water boards until 1850. From the 1850s onward, water boards were introduced in these higher regions as well, and agronomical scientists and organisations like the Nederlandse Heidemaatschappij endeavoured for the modernisation of agricultural water management. One of their priorities was the introduction of modern forms of surface irrigation of pastures, in order to increase crop yields. In various places modern irrigation systems were constructed. From the 1900s onward, these systems were abandoned due to the introduction of new chemical fertilizers, among others. This article describes the construction and abandonment of one of these modern irrigation systems that was located in Liempde, in the province of Noord-Brabant. The local farmers were not interested in the new technique, and within a few years the system was transformed in a poplar plantation. Nowadays, the area is part of a nature reserve. Nonetheless, the global layout of the irrigation system is still visible.

Water supply in the sandy dry lands (the Netherlands). Spatio-temporal developments

Wells as water facilities were standard elements of the Dutch settlement landscape only since the Roman period. At the same time (drinking) water facilities became largely detached from the local topography. The position of a well within a settlement became determined by that of its associated house, and its position relative to the house became more or less fixed. This reflects the functional and social subdivision of the farmhouse into two distinct sections: ‘front’ and ‘back’. Communal water facilities (socially important as well) seem to have been associated with nucleated settlement, and they always existed alongside private facilities. Communal (public) wells first appeared in towns around the 13th or 14th century, but in rural areas probably not until the 16th century. In different periods there is evidence for the expression of social and functional differentiation.

‘A balance between remembrance and promise’. An interview with Eric Luiten about landscape and the spatial dynamics of the New Dutch Waterline as a World Heritage

In 2019 the New Dutch Waterline was nominated for the World Heritage List. Recently the chair of the quality team New Dutch Waterline, Eric Luiten, left office. The New Dutch Waterline became one of the key-projects of the Nota Belvedere (1999) of the Dutch government, which promotes the preservation of heritage through development. Luiten, together with others, developed a plan called ‘Line perspective’, in which developments were not seen as a threat, but welcomed. In contrast to the conservative approach towards heritage, in which a historic site or monument is often shielded from change, Luiten’s approach embraces these changes. He hopes this project can serve as an international example for the preservation through development approach, even if the New Dutch Waterline is not inscribed as World Heritage.

Living with water. The Dijkenkaart of the Netherlands

De Cultural Heritage Agency made an interesting digital map (in GIS) of all the dikes in the Netherlands. This was possible by using existing digital maps, but new research was necessary to make this general overview. There was discussion about the dating of dikes, because dikes can be of medieval origin, but were adjusted over time. Besides dikes, researchers find GIS and historical information on poldermills, kolks, reclamations and pumping stations. That is why this map is called ‘Living with water’, because this information can help addressing new challenges in climate adaptation strategies dealing with water. Everyone can take a look, or download the map in GIS, on www.cultureelerfgoed.nl/onderwerpen/bronnen-en-kaarten/overzicht/levenmet-water-kaart.
Ontstaan en vroege ontwikkeling van Kampen

The emergence and early development of Kampen

The town Kampen, at the mouth of the river IJssel (The Netherlands), seems to have originated in the 12th century ex nihilo. To explain this enigmatic start, many theories have been proposed. This article attributes its origin to a series of events, that started with the silting up of the Limjefjord after 1120 in the north of Jutland. This fjord was an important connection between the North Sea and the Baltic Sea for the small boats of the Frisian trade. The silting up of the fjord was a direct reason for the creation of the cog, a larger bulk carrier, that could circumnavigate Cape Skagen. Moreover, it could also take a shortcut over high seas to the mouth of the Vlie, and over the Almere to the mouth of the river IJssel. From there, the smaller Frisian ships used to sail over the IJssel to the German Rhine area, which was impossible for the seagoing cog. Therefore, the introduction of the cog prompted the foundation of a port for transshipment in the first half of the 12th century. This means Kampen did already exist as a settlement, when a storm surge in 1170 turned the Almere into the Zuiderzee and the settlement could take advantage of this environmental change.

The Festung IJmuiden and the works in the dunes

The Atlantic Wall was an extensive system of coastal defence and bunkers built by Nazi Germany between 1942 and 1944. In the Netherlands, two so-called Festungen were built to protect the harbours which were of great interest for the German occupiers. This map shows the Festung IJmuiden, built around the locks and harbours. The steelworks at the north side were also protected by this fortification. Besides different types of bunkers it also consisted of anti-tank ditches, antitank walls, dunes, minefields and hospitals. After the Second World War the traces of Nazi Germany were partly removed, also in this part of the Atlantic Wall. But many elements have remained and are more and more appreciated as cultural heritage.

An age-long struggle against drought and downfall. Values and meanings of the Curaçao plantation landscape

Even if it is not obvious at first, a closer look reveals that Curaçao is actually one large plantation landscape, with the exception of Willemstad’s inner city. This landscape can be read as a history book with the old plantation houses as its most recognizable elements. But there are many more elements like cactus hedges, palm copses, stone walls, wells and (dysfunctional) waterworks. This landscape is most recognizable in the western part of the island. The central area around Willemstad has suffered from uncontrolled urbanization and industrialization, while the eastern part has basically become an extensive leisure landscape. The owners of plantations used several strategies like a multitude of crops, the creation of saltpans where possible and trade in the city (just a few plantation owners focused exclusively on agricultural production). At the end of the 19th century, several plantations were explored for extractable minerals. Throughout the 20th century, almost all plantations were gradually sold and abandoned. The abolishment of slavery in 1863 gave the first impetus for this, but the final blow was the exodus towards the city when an oil refinery brought new perspectives for the island. Paid employment in the city was much more appealing than an uncertain existence in the countryside, where years of failed crops could eventually lead to starvation. An overall problem is the ongoing privatization of public space, which results in the transformation of old plantations into gated residential areas and resorts, creating an unrecognizable landscape and a growing inequality between rich and poor. A future nomination for the UNESCO World Heritage List will possibly create new perspectives for this cultural landscape (see next article).

Saba, the unspoiled Queen of the Antilles

The isolated Caribbean island of Saba is affectionately called ‘the unspoiled Queen’, due to the unaffected character of its natural environment. European colonists from Zeeland (The Netherlands) and the British Isles occupied the island four centuries ago and partially changed it into a cultural landscape with an outstanding character and a vernacular architecture that is worth to be well protected.

The inhabitants – still no more than 2000 – had to adjust to the rugged and mountainous landscape. This is expressed by the location of the villages, the network of paths and stairs connecting them, the construction and size of the wooden cottages and the cisterns and burial sites on their properties. This combination makes Saba unique in the Caribbean region. The Saban architecture which is rooted in a Victorian-British building tradition, has hardly changed over the years, though building in concrete is a serious threat nowadays.

The ubiquitous network like Mobile Cloud Computing (MCC) provides a high quality of wireless services depending upon the wireless communication system network security level. And so many researches are carried out by the researcher on security algorithms for wireless communication system constructed in different network reliability. In our proposed thesis paper, on a theoretical basis, we developed the theory of MCC Security Layer Protocol security system in which we used the cryptographic hash function SHA-256 to generate a private key for entities, RC5 encryption, and decryption algorithm, Temporal Key Integrity Protocol (TKIP) generating a dynamic sequential key and CRC-32 checksum to detecting the error in our packets. The MSLP uses the stored symmetric secret key calculated on the basis of the Diffie-Hellman Key sharing scheme to generate keystream for cryptography functions. The secret key stored in the device’s filesystem our database prior to the deployment on Mobile Cloud Computing and remains the same throughout the session of communication. These systems use the dynamic initialization vector to avoid reply attacks and message integrity code calculated on source and destination devices addresses and actual frame contents. In the proposed thesis paper we analyze the security measures at the MSLP level and before transmitting information over the mobile networks, the information is encrypted in the form of frames and at the physical layer, this frame converted into its equivalent radio signals.
DARK SIDE OF PARADOXICAL LEADERSHIP: SOCIAL COMPARISION THEORY PERSPECTIVE
Authors: Bashir Fatima
Published: June 2021

Considerable research has viewed Paradoxical leadership as a positive style of leadership in different contextual settings. But little is known how paradoxical behavior of a leader can be detrimental for followers. The present study proposed etic view of paradoxical leadership based on social comparison theory explaining how and why people make comparison with similar and dissimilar others, that might lead to interpersonal conflict which may trigger negative outcomes. We have proposed and tested a sequential mediation model between Paradoxical leadership and employee job stress through interpersonal conflict and job insecurity. The study is based on time lagged data (3 intervals apart by one month each) from 285 service sector employees of Pakistan. All measures used were validated before testing mediation model. Structure equation modeling has been used for model testing that provided a good support to the hypothesized model. Results justified that when employees make comparison among each other on the basis of leader’s behavior with them, and indulge in interpersonal conflicts and feel more job insecurity that ultimately proceeds towards their job stress.
INFLUENCE OF WOOD SAW DUST AND WASTE GLASS ADMIXTURE ON SELECTED PROPERTIES OF FIRED CLAY BRICKS FOR MASONRY
Authors: Folorunso D.O.
Published: June 2021

This study investigated the effect of mahogany wood sawdust (WSD) and waste glass (WG) addition on the properties and cost of producing fired clay bricks for construction of houses. Materials used were clay, WSD and WG. Brick samples were produced in batches and labeled as samples A (with no additives), B, C, D, E, F, G and H. Each sample of B, C, D, E, F, G and H contained 5% fixed amount of WSD, and 10, 15, 20, 25, 30, 35 and 40% of WG respectively. Brick samples produced were tested for apparent porosity, bulk density, compressive and flexural strengths, thermal conductivity and wear. Results obtained showed that as waste glass content increased in the samples, bulk density and compressive strength increased due to enhancement of densification and compaction within the samples. Thermal conductivity also increased as waste glass increased due to reduction in porosity and reduced inter-particle distance. The value of flexural strength increased with WG content but at 35% and 40%, the value reduced. This is as a result of an increase in brittleness as waste glass content increased which increased stress concentration in the samples, hence leading to a reduction in flexural strength. Also, it was observed that the increase in the content of the waste glass led to a reduction in the value of apparent porosity and wear depth due to improved cohesion between particles in the bricks. Comparing results obtained with existing standards and considering the cost of production, 5% WSD and 25% WG addition, with apparent porosity of 26.3%, compressive strength of 17.5 MPa, thermal conductivity of 0.32 W/mk and wear depth of 1.72 mm is recommended for construction purposes.

B-cell acute lymphoblastic leukemia (B-ALL) is the most aggressive and lethal hematologic malignancy without moment treatment. The outcomes from clinical trials across different institutions report an impressive remission rate with CD19-targeted CAR-T cell treatment. Although the success and the accomplishment of the clinical efficiency of CAR-T cell treatment, critical adverse side effects such as toxicities can occur. Cytokine release syndrome, defined as an inflammatory syndrome associated with exponential T-cell proliferation with resultant marked high cytokine levels, and neurotoxicity are the foremost common toxicities and can be severe or even deadly. In this mini-review, we will briefly sum up the results of nineteen studies of CD19-targeted CAR-T cell therapy in patients with relapsed/refractory B-cell ALL.

In this paper we consider perturbations of a second order differential equation of the spectral problem with a loaded term, containing a value of the unknown function at the point zero, with regular, but not strongly regular boundary value conditions. Question about basis property of eigen functions and associated functions (E&AF) systems of a loaded multiple differentiation operator is studied. In the case of non-self-adjoint ordinary differential operators, the basis property of systems of eigen functions and associated functions (E&AF), in addition to the boundary value conditions, can be affected by values of coefficients of the differential operator. Moreover, it is known that the basic properties of E&AF can be changed at a small change of values of the coefficients. This fact was first noted in Il’in V.A. In this paper problem non stability on basis property of systems root vectors of a loaded multiple differentiation operator.

Published: June 2021

When solving differential equations with variable coefficients, especially when the coefficients degenerate at the boundary of a given domain, problems arise in the formulation of boundary value problems. Usually, differential equations with variable coefficients are investigated in a suitable weight functional space. Often in the role of such spaces the weight Sobolev space or various generalizations are considered, which are currently sufficiently studied. However, in some cases, when the coefficients of the considered differential equation are strongly degenerate, the formulation of boundary value problems becomes problematic. In this work, we consider the so-called space with multiweighted derivatives, where after each derivative, the function is multiplied by the weight function and then the next derivative is taken. By controlling the behavior of the weight functions on the boundary, strongly degenerate equations can be investigated. Here we investigate the existence of traces on the boundary of a function from such spaces.

Problems of solving different linear difference equation is given to study the properties of the matrix operators in various functional spaces. One of the important problems of functional analysis is to establish criteria of boundedness of the linear operators in functional spaces. Question of the boundedness of matrix operators in sequence spaces is a classic problem of functional analysis and there are many unsolved problems in it. For example, in the general case it is impossible to establish the boundedness of the matrix operator in the spaces of sequences by the given matrix. Therefore, various classes of matrix operators are considered for which the criteria of their boundedness are known. Due to the variety of encountered problems in practice, it is necessary to have various alternative criteria for the boundedness of matrix operators. In this paper, we establish a new alternative criterion for the boundedness of one class of matrix operators.

In this paper, we investigate the boundedness of the norm of the convolution operator in anisotropic Triebel-Lizorkin spaces. The Triebel-Lizorkin spaces are based on the Lorentz spaces pq L . In the anisotropic case, we take the anisotropic Lorentz space pq L as the base. The main goal of the paper is to solve the following problem: let f and g be functions from some classes of the Triebel-Lizorkin space scale. It is necessary to determine which conditions on the parameters of the spaces from f and g are taken and study which space belongs to their convolution gf  . An analogue of the O'Neil theorem was obtained for the Triebel-Lizorkin space scale αq pτF , where α , τ, p , q are vector parameters. Relations of the form γξ hν βη rμ F F  ↪ αq pτF are obtained, with the corresponding ratios of vector parameters γ βα  , hrp 11 1 1   , νμτ 111  , ηξq 111  . The research method is the functional spaces theory and inequalities of functional and harmonic analysis.

This work is intended to develop a new direction of theoretical and nuclear astrophysics by studying reactions that occur at high pressure on the crusts of neutron star. Interest in neutron stars is related to the mystery of its structure. In addition, there are a high density, an extremely strong magnetic and gravitational fields. The physical properties of leptons in weak interaction are involved and provided. The manifestation of lepton universality is discussed. The decay of the muon was investigated in the standard model. The ways in which muons occur in denser matter are studied. The muon is a very unstable particle on Earth. Its lifetime is a few microseconds. However, in a very dense, neutron star, it is stable. The appearance of muons in the composition of denser stars, that is, the transformation of the electron into a muon is energetically advantageous. It can also participate in some nuclear reactions.

This article reveals the problem of the formation of a modern style of thinking, a logical culture among students in STEM education. The modern educational system is aimed at orienting the student to incentives and assessments received from the outside, from society. In the conditions of rapidly developing information technology, it became possible to more clearly demonstrate many “real experiments” in real time using the knowledge gained in the lessons. In particular, we analyzed the effectiveness of using the STEM condition in physics lessons. We examined the benefits of STEM technology. A study of two identical lessons was carried out in which we prove that the new approach improves the interest and cognition of students. The use of STEM technologies in physics classes shows an improvement in the quality of education, as well as attracting students to the world of science.

Since the main form of teaching in higher education is a lecture, the main didactic goal of the lecture is to form the necessary basis for teaching students teaching materials. The most vulnerable aspect of traditional education is the students' indifference to the one-sided high activity of the teacher. For this reason, the number of lecture types has recently increased. Lectures using feedback methods are one way to energize students. One of the ways to effectively use information technology is to provide virtual feedback to students during lectures. In this work, an experiment was carried out using a virtual feedback tool. The importance of virtual feedback is emphasized and practical examples are given

The development of a model for the effective use of water resources is one of the priorities of Kazakhstan. About half of the Republic's surface water (44.9 cubic km) comes from the territory of neighboring countries. According to experts, the increasing water intake by neighboring countries and the deterioration of water quality in the country's rivers can lead to an environmental disaster. In this regard, the analysis and discussion of models for the efficient allocation of water resources in transboundary river basins, which are already successfully used in the world, will be an urgent solution. This article discusses effective models and ways to solve water resources problems in transboundary rivers that have already been applied to transboundary rivers, and based on these models, a hybrid model is built that can be applied to transboundary rivers of the country.

Formation of urban agglomerations is related to formation of logistics infrastructure, inefficiency of which leads to emergence of a number of social and economic problems. The search of a solution of these problems is complicated by lack of high quality theoretical and methodological instruments of logistics infrastructure management. According to the research materials and fundamental scientific papers on logistics and supply chain management along with the theory and methodology of logistics infrastructure development, the author considers theoretical and methodological foundations of management of urban agglomeration logistics infrastructure. The article also contains theoretical oundations of urban agglomeration logistics infrastructure management, offers the author’s definition of the term «integrated logistics infrastructure» and contains a hierarchical concept of urban agglomeration logistics infrastructure management that is a prerequisite to devising of a corresponding organizational and functional model.

In the modern world, there is often a time when the relevance of actions is not necessary, in addition, there is a need to predict further stages of activity. All this is possible thanks to the use of regression analysis, which is used in many areas of activity. This article describes the application of this analysis to Bank risk, namely credit risk. Computational and theoretical studies on the processing of big data of banking institutions based on regression analysis, namely the method of multiple regression, have been carried out. In addition, this article provides a forecast based on various economic changes. This is very important for the banking sector, primarily because these studies reflect trends in credit risk.

In this paper, we comprehensively consider the problems that depend on the parameter. The necessary and sufficient conditions for the existence of a unique solution of equations and systems of equations that depend on the parameter are investigated. Finding solutions to equations and systems of equations that depend on parameters is one of the most difficult areas of elementary mathematics. To solve them, you need to find ways that require special logical thinking, which must satisfy some additional conditions, for example, to determine a single solution, a solution in a set of all possible values of unknowns, cases when all the solutions of one system are solutions of another, and so on. One of these cases is the use of invariant properties. The article uses various examples of using invariant properties of transformations to consider methods and techniques for solving equations and systems of equations that depend on a single parameter. As a result, due to the presence of invariant properties of transformations, we see that the desired solution is found quickly and easily.

The article focuses on the consideration of econometric models of stock quotes of large domestic companies based on modeling the securities portfolio and predicting its behavior using mathematical modeling using elements of probability theory and mathematical statistics. It is also shown how the problem of choosing the optimal portfolio can be reduced to the problem of convex quadratic programming. In this article, based on the Markowitz model, a model of an optimal investment portfolio with bilateral restrictions on variables associated with the requirements of the law is developed. An example is considered in which 10 types of stocks and bonds of large Kazakhstani companies are selected, which generates an optimal set of assets and calculates the risk of an optimal portfolio for a given level of expected return. Based on the results obtained, companies and entrepreneurs can build a strategy for investing and buying shares, knowing the probable income from a portfolio of certain types of securities.

Electric supply system in enterprises must provide with electrical supply continuity and reliability as in normal and accidental regimes, quality electro energetic, production efficiency, so in connection with these in the article there have been analyzed work regimes of substations, studied electrical net scheme for Kentau Transformer Plant’s substation, calculated plant’s loads and short circuit currents and on the base of the calculated results curried out inspection for the chosen equipment. The number of connections, reliability of power supply and prospects for development are the determining factors for choosing the electrical scheme of high-voltage switchgears. You also need to take into account the need to conduct audits and tests of switches without interruption. In our case, we have four connections: two communication lines with electrical systems and two transformers. The distribution devices of the substation of the Kentau transformer plant are connected to the transformers according to a block scheme. Electrical installations are connected to the network transformer unit or receive backup power from another substation, since in case of failure of one network, both transformers can not work with the rest of the network. Based on this, measures are proposed for the reconstruction of the substation, with the replacement of the block diagram of the switchgear with the circuit for connecting the power transformer to the switchgear by a bus bridge. Offered measurements on reconstruction of the substation by replacing block scheme of switchgears to scheme of power transformer connection with DD bus bridge. Worked out main modernization problems of the substation switchgear, done calculation and selection of distributing bus bars for arranging switchgear.
