Class I histone deacetylases (HDACs) generally promote cell proliferation and tumorigenesis, whereas class IIA HDACs like HDAC4 and HDAC5 may promote or impede cancer development in a tissue-dependent manner. In urothelial carcinoma (UC), HDAC5 is often downregulated. Accordingly, HDAC5 was weakly expressed in UC cell lines suggesting a possible tumor-suppressive function. We therefore characterized the effects of stable HDAC5 expression in four UC cell lines (RT112, VM-Cub-1, SW1710 and UM-UC-3) with different phenotypes reflecting the heterogeneity of UC, by assessing proliferation, clonogenicity and migration ability. Further, we detailed changes in the proteome and transcriptome by immunoblotting, mass spectrometry and RNA sequencing analysis. We observed that HDAC5 overexpression in general decreased cell proliferation, but in one cell line (VM-Cub-1) induced a dramatic change from an epitheloid to a mesenchymal phenotype, i.e., epithelial-mesenchymal transition (EMT). These phenotypical changes were confirmed by comprehensive proteomics and transcriptomics analyses. In contrast to HDAC5, overexpression of HDAC4 exerted only weak effects on cell proliferation and phenotypes. We conclude that overexpression of HDAC5 may generally decrease proliferation in UC, but, intriguingly, may induce EMT on its own in certain circumstances.

Authors: Wen Hao , Zhang Xiaoxing , Xia Rong , Hu Guoxiong , Wu Yunjian
Published: April 2019

In this paper, the flashover discharging experiment was carried out on epoxy resin surface in an SF6 atmosphere under pin-plate electrodes, with the electrodes distance from 5 mm to 9 mm. The concentration of seven characteristic gases was detected, indicating that the concentration of SOF2 and CF4 was the two highest, followed by SO2, CO2, SO2F2, CS2, and H2S. Based on the changes in the concentration of the characteristic gases, a preliminary rule was proposed to predict the occurrence of flashover discharge on epoxy resin: When the concentration of SOF2 reaches twice of CF4 concentration, and the total concentration of both SOF2 and CF4 is much higher than that of H2S, a possible flashover discharge on the epoxy resin surface in SF6-infused electrical equipment occurs. Through the simulation of decomposition of epoxy resin, it has been revealed that H2O has different generation paths that can facilitate the formation of SOF2, finally influencing the concentration variation of the seven characteristic gases.
A Measurement-Data-Driven Control Approach towards Variance Reduction of Micromachined Resonant Accelerometer under Multi Unknown Disturbances
Authors: Shen Qiang , Yang Dengfeng , Zhou Jie , Wu Yixuan , Zhang Yinan , Yuan Weizheng
Published: April 2019

This paper first presents an adaptive expectation-maximization (AEM) control algorithm based on a measurement-data-driven model to reduce the variance of microelectromechanical system (MEMS) accelerometer sensor under multi disturbances. Significantly different characteristics of the disturbances, consisting of drastic-magnitude, short-duration vibration in the external environment, and slowly-varying, long-duration fluctuation inside the sensor are first constructed together with the measurement model of the accelerometer. Next, through establishing a data-driven model based on a historical small measurement sample, the window length of filter of the presented algorithm is adaptively chosen to estimate the sensor state and identify these disturbances simultaneously. Simulation results of the proposed AEM algorithm based on experimental test are compared with the Kalman filter (KF), least mean square (LMS), and regular EM (REM) methods. Variances of the estimated equivalent input under static condition are 0.212 mV, 0.149 mV, 0.015 mV, and 0.004 mV by the KF, LMS, REM, and AEM, respectively. Under dynamic conditions, the corresponding variances are 35.5 mV, 2.07 mV, 2.0 mV, and 1.45 mV, respectively. The variances under static condition based on the proposed method are reduced to 1.9%, 2.8%, and 27.3%, compared with the KF, LMS, and REM methods, respectively. The corresponding variances under dynamic condition are reduced to 4.1%, 70.1%, and 72.5%, respectively. The effectiveness of the proposed method is verified to reduce the variance of the MEMS resonant accelerometer sensor.

Published: April 2019

This paper aims to carry out an archaeometric characterization of mortar samples taken from an underwater environment. The fishpond of the archaeological site of Castrum Novum (Santa Marinella, Rome, Italy) was chosen as a pilot site for experimentation. The masonry structures reached the maximum thickness at the apex of the fishpond (4.70 m) and consisted of a concrete conglomerate composed of slightly rough stones of medium size bound with non-hydraulic mortar. After sampling, for a complete characterization of selected mortar fragments, different and complementary techniques (stereomicroscopy, polarizing optical microscopy, and X-ray powder diffraction analysis) were carried out in order to: a) define the minero-petrographic features; and b) investigate their state of conservation. The obtained data allowed the determination of the main constituents of mortars from a compositional point of view. The raw materials, in fact, were quite homogeneous, as well as the ratio in which they were mixed, confirming the typical "recipe" used in Roman times to manufacture hydraulic-type mortars by adding pozzolana. At the same time, it was possible to identify the various degradation processes we were interested in, namely, biological colonization (bio-fouling) that develops differently according to environmental conditions. Based on characterization phase results, the research will help to develop adequate techniques for intervention (innovative tools and methods for the protection of underwater cultural heritage) with particular regard to cleaning and consolidating procedures to be carried out directly in situ.
Tell Them How They Did: Feedback on Operator Performance Helps Calibrate Perceived Ease of Use in Automated Driving
Authors: Forster Yannick , Hergeth Sebastian , Naujoks Frederik , Krems Josef , Keinath Andreas
Published: April 2019

The development of automated driving will profit from an agreed-upon methodology to evaluate human–machine interfaces. The present study examines the role of feedback on interaction performance provided directly to participants when interacting with driving automation (i.e., perceived ease of use). In addition, the development of ratings itself over time and use case specificity were examined. In a driving simulator study, N = 55 participants completed several transitions between Society of Automotive Engineers (SAE) level 0, level 2, and level 3 automated driving. One half of the participants received feedback on their interaction performance immediately after each use case, while the other half did not. As expected, the results revealed that participants judged the interactions to become easier over time. However, a use case specificity was present, as transitions to L0 did not show effects over time. The role of feedback also depended on the respective use case. We observed more conservative evaluations when feedback was provided than when it was not. The present study supports the application of perceived ease of use as a diagnostic measure in interaction with automated driving. Evaluations of interfaces can benefit from supporting feedback to obtain more conservative results.
Analyzing Changes in Supply Risks for Abiotic Resources over Time with the ESSENZ Method—A Data Update and Critical Reflection
Authors: Bach Vanessa , Berger Markus , Finogenova Natalia , Finkbeiner Matthias
Published: April 2019

In the last decade, several methods were developed to determine potential supply risks due to short term socio-economic aspects. One of them is the ESSENZ method (comprehensive method to measure and assess resource efficiency of products in the context of sustainable development) developed by the authors. Due to newly available data (e.g., production statistics) the characterization factors (CFs) of the ESSENZ method were updated (based on data from the years 2011 to 2015, with focus on 2014 and 2015) and compared with the original CFs (based on data from the years 2009 to 2013, with focus on 2012 and 2013) for six of the overall eleven categories. The goal of the paper is to analyze if changes in the underlying data are adequately reflected in the CFs of ESSENZ for the considered categories. Further, the updated CFs are provided. The six categories are analyzed by comparing original and updated CFs and clustering them into four groups: declining, emerging, persistent, and non-occurring potential supply risks. Significant differences in the CFs are evaluated by analyzing changes in the underlying data as well as the steps to determine the CFs. It could be shown, that for most of the considered categories and resources changes in the underlying data are reflected adequately in the CFs. However, some methodological challenges of ESSENZ, which limit the reflection of potential supply risks changes, could also be identified.
A Mature-Tomato Detection Algorithm Using Machine Learning and Color Analysis
Authors: Liu Guoxu , Mao Shuyi , Kim Jae Ho
Published: April 2019

An algorithm was proposed for automatic tomato detection in regular color images to reduce the influence of illumination and occlusion. In this method, the Histograms of Oriented Gradients (HOG) descriptor was used to train a Support Vector Machine (SVM) classifier. A coarse-to-fine scanning method was developed to detect tomatoes, followed by a proposed False Color Removal (FCR) method to remove the false-positive detections. Non-Maximum Suppression (NMS) was used to merge the overlapped results. Compared with other methods, the proposed algorithm showed substantial improvement in tomato detection. The results of tomato detection in the test images showed that the recall, precision, and F1 score of the proposed method were 90.00%, 94.41 and 92.15%, respectively.
Thermal Analysis of a Magnetic Brake Using Infrared Techniques and 3D Cell Method with a New Convective Constitutive Matrix
Authors: Monzón-Verona José Miguel , González-Domínguez Pablo Ignacio , García-Alonso Santiago , Santana-Martín Francisco Jorge , Cárdenes-Martín Juan Francisco
Published: April 2019

In this work we analyse the temperature distribution in a conductor disk in transitory regime. The disk is in motion in a stationary magnetic field generated by a permanent magnet and so, the electric currents induced inside it generate heat. The system acts as a magnetic brake and is analysed using infrared sensor techniques. In addition, for the simulation and analysis of the magnetic brake, a new thermal convective matrix for the 3D Cell Method (CM) is proposed. The results of the simulation have been verified by comparing the numerical results with those obtained by the Finite Element Method (FEM) and with experimental data obtained by infrared technology. The difference between the experimental results obtained by infrared sensors and those obtained in the simulations is less than 0.0459%.
Phenotyping of Plant Biomass and Performance Traits Using Remote Sensing Techniques in Pea (Pisum sativum, L.)
Authors: Quirós Vargas Juan José , Zhang Chongyuan , Smitchger Jamin A. , McGee Rebecca J. , Sankaran Sindhuja
Published: April 2019

Field pea cultivars are constantly improved through breeding programs to enhance biotic and abiotic stress tolerance and increase seed yield potential. In pea breeding, the Above Ground Biomass (AGBM) is assessed due to its influence on seed yield, canopy closure, and weed suppression. It is also the primary yield component for peas used as a cover crop and/or grazing. Measuring AGBM is destructive and labor-intensive process. Sensor-based phenotyping of such traits can greatly enhance crop breeding efficiency. In this research, high resolution RGB and multispectral images acquired with unmanned aerial systems were used to assess phenotypes in spring and winter pea breeding plots. The Green Red Vegetation Index (GRVI), Normalized Difference Vegetation Index (NDVI), Normalized Difference Red Edge Index (NDRE), plot volume, canopy height, and canopy coverage were extracted from RGB and multispectral information at five imaging times (between 365 to 1948 accumulated degree days/ADD after 1 May) in four winter field pea experiments and at three imaging times (between 1231 to 1648 ADD) in one spring field pea experiment. The image features were compared to ground-truth data including AGBM, lodging, leaf type, days to 50% flowering, days to physiological maturity, number of the first reproductive node, and seed yield. In two of the winter pea experiments, a strong correlation between image features and seed yield was observed at 1268 ADD (flowering). An increase in correlation between image features with the phenological traits such as days to 50% flowering and days to physiological maturity was observed at about 1725 ADD in these winter pea experiments. In the spring pea experiment, the plot volume estimated from images was highly correlated with ground truth canopy height (r = 0.83) at 1231 ADD. In two other winter pea experiments and the spring pea experiment, the GRVI and NDVI features were significantly correlated with AGBM at flowering. When selected image features were used to develop a least absolute shrinkage and selection operator model for AGBM estimation, the correlation coefficient between the actual and predicted AGBM was 0.60 and 0.84 in the winter and spring pea experiments, respectively. A SPOT-6 satellite image (1.5 m resolution) was also evaluated for its applicability to assess biomass and seed yield. The image features extracted from satellite imagery showed significant correlation with seed yield in two winter field pea experiments, however, the trend was not consistent. In summary, the study supports the potential of using unmanned aerial system-based imaging techniques to estimate biomass and crop performance in pea breeding programs.
Bridging Intellectual Capital and SMEs Internationalization through the Lens of Sustainable Competitive Advantage: A Systematic Literature Review
Authors: Vătămănescu Elena-Mădălina , Gorgos Elena-Alexandra , Ghigiu Alexandru Mihai , Pătruț Monica
Published: April 2019

The aim of the current paper is advance a comprehensive framework meant to bridge three major concepts, namely intellectual capital (IC), the internationalization process of small and medium-sized enterprises (SMEs) and the achievement of sustainable competitive advantage. The paper stresses upon a managerial perspective within the internationalization context, investigating the human, structural and relational capital apposite to managers or entrepreneurs. By directly addressing the relationships among the constructs, the endeavor is complementary to previous systematic reviews on similar topics which tangentially discuss the conceptual triad and thus proposes an integrative research agenda for future interdisciplinary studies straddling the fields of management, business, entrepreneurship and sustainability. In terms of methodology, a systematic literature review was envisaged, by applying a stepwise approach and multifold criteria. Over 100 scientific articles published in peer-reviewed journals were scrutinized and considered in the analysis. The literature review revealed that conceptual papers in the field are scarce despite the variety of their aims and approaches. The quantitative-based empirical studies prevail over the qualitative ones, while mixed methods research designs are scant. In terms of content, the extant studies fall short to advance research and structural models testing and assessing the specific relations among constructs and avail new research avenues focused on the underlying processes of SMEs internationalization by means of intellectual capital harnessing and sustainable competitive advantage achievement.
Systematic Review of Integrated Sustainable Transportation Models for Electric Passenger Vehicle Diffusion
Authors: Lopez-Arboleda Esteban , Sarmiento Alfonso T. , Cardenas Laura M.
Published: April 2019

Ensuring energy security, stopping climate change, and improving urban air quality are the three main challenges of this century that are being addressed by governments globally. The transportation sector contributes significantly to these issues. Sustainable transport involves the consideration of three dimensions—economic development, environmental preservation, and social development—and one of its aspects is the focus on the transition towards electric vehicles. The sustainable transportation is a complex system with multiple relationships and feedback between their elements. Understanding this complexity in an integrated and holistic manner is a challenge that must be addressed. To obtain insight into this complexity, we perform a systematic review of studies in which the demand and supply components of the passenger transportation sector were modelled in an integrated manner along with the dimensions of sustainability. All the reviewed previous studies had taken into consideration both the economic and environmental dimensions; however, only a few had also considered social development. The holistic and systematic integration of the dimensions of sustainability along with their relationships and feedback would facilitate a better understanding of the transportation sector and promote the development of better policies for improving the diffusion of passenger electric vehicles.

Published: April 2019

This paper considers the Lie symmetry analysis of a class of fractional Zakharov-Kuznetsov equations. We systematically show the procedure to obtain the Lie point symmetries for the equation. Accordingly, we study the vector fields of this equation. Meantime, the symmetry reductions of this equation are performed. Finally, by employing the obtained symmetry properties, we can get some new exact solutions to this fractional Zakharov-Kuznetsov equation.
Impact of Unsteady Flow Events on Bedload Transport: A Review of Laboratory Experiments
Authors: Mrokowska Magdalena M. , Rowiński Paweł M.
Published: April 2019

Recent advances in understanding bedload transport under unsteady flow conditions are presented, with a particular emphasis on laboratory experiments. The contribution of laboratory studies to the explanation of key processes of sediment transport observed in alluvial rivers, ephemeral streams, and river reaches below a dam is demonstrated, primarily focusing on bedload transport in gravel-bed streams. The state of current knowledge on the impact of flow properties (unsteady flow hydrograph shape and duration, flood cycles) and sediment attributes (bed structure, sediment availability, bed composition) on bedload are discussed, along with unsteady flow dynamics of the water-sediment system. Experiments published in recent years are summarized, the main findings are presented, and future directions of research are suggested.

Authors: Rivera-Vargas Juan , Bolaños-Valverde María Laura
Published: April 2019

Los estímulos electromagnéticos han demostrado su utilidad en el manejo de úlceras de cualquier tipo, debido a que sus efectos estimulan la liberación de fibroblastos y macrófagos en la zona afectada, el crecimiento y la diferenciación celular. Así mismo, permite dirigir de manera eficaz la bioelectricidad endógena, la cual representa un factor esencial en el proceso de curación corporal. El reporte de caso que se expone a continuación es de una usuaria de 87 años de edad, quien asiste a la Clínica Santa Paula a consulta por una ulcera vascular venosa en su pierna izquierda de un año de evolución, la cual había sido tratada con recursos médicos y farmacológicos sin resultados positivos. Se aplicaron las modalidades eléctricas de Alto Voltaje y Microcorriente sin ningún otro tratamiento coadyuvante o tipo de ejercicio, durante 21 sesiones atendiéndose en promedio cada 7,8 días, mejorando un 4,47% el diámetro de la herida por sesión y obteniendo una resolución completa de la herida en 4 meses de tratamiento. Conclusiones: Los agentes electro físicos como la Microcorriente y el Alto Voltaje son recursos idóneos para facilitar procesos endógenos de reparación tisular, así mismo el razonamiento clínico y la evaluación diaria y meticulosa son fundamentales para una dosificación correcta ya que no existen protocolos establecidos para su uso.
What do Bohemian Waxwings Bombycilla garrulus find on agricultural fields in winter?
Authors: De Jong Adriaan "Adjan" , Olsson Fredrik
Published: April 2019

We describe three cases when Bohemian Waxwings Bombycilla garrulus behaved as if they were searching for food on the ground in frozen fields in the winter. Inspection of the sites where they searched revealed little or no available food items. In one case the droppings contained juniper seeds but these must have been consumed elsewhere as there were no junipers at the site. Drinking water may have been the explanation in one case where upwelling water flowed over the ice. We speculate that eating minerals is another possible explanation, but leave the question open.
Shift in migration phenology of a wintering population of Dippers Cinclus cinclus in northern Sweden
Authors: Johansson Frank , Brodin Tomas , Strasevicius Darius , Fürstenberg-Hägg Emil
Published: April 2019

Many organisms have been found to respond to global warming by adjusting one or several aspects of their ecology, such as timing of migration events, time at reproduction and size at maturity. We examined changes in arrival and departure times, and age and sex ratios of overwintering White-throated Dippers Cinclus cinclus in northern Sweden, by comparing data collected in 1975–1979 to a similar dataset from 2010–2014. Between these periods, the average winter temperature had increased by about 2°C. During the latter period the Dippers arrived in their winter area two weeks earlier and departed three weeks earlier. We found no change in age and sex ratios during the study period.
Förändringar av häckfåglar på en sydsmåländsk gård från 1970- till 2010-talet
Authors: Nilsson Sven G
Published: April 2019

I compare the number of breeding birds of a 70 ha farm in a forest region of southern Sweden between the 1970s and the 2010s. The most important habitat change was replacement of 25 hectares 100 years old mixed forest by spruce plantation. Stands dominated by deciduous trees only grew older, and pastures were grazed by cattle both periods. More species decreased than increased, especially residents and tropical migrants decreased. For short distance migrants, the number of decreasing species were balanced by a similar number of increasing species. The density change of most species could be attributed to the replacement of the old mixed forest by the spruce plantation. Species preferring deciduous forest had much higher densities in the study plot than the regional averages. Two deciduous forest species, Pied Flycatcher Ficedula hypoleuca and Marsh Tit Poecile palustris declined strongly, the latter possibly due to competition from the increasing Blue Tit Cyanistes caeruleus. The Starling Sturnus vulgaris and the Tree Pipit Anthus trivialis stands out as drastically decreasing much more than local habitat changes can explain.
Changes in local distribution and numbers of staging and wintering Bean Geese Anser fabalis in Scania, south Sweden 1977/1978–2016/2017
Authors: Nilsson Leif
Published: April 2019

Scania in southern Sweden is an important staging and wintering province for the Bean Goose Anser fabalis, especially for the Taiga form A. f. fabalis. Based on counts in October, November and January 1977/1978–2016/2017, and observations of neck-banded individuals, the changes in local distribution are described. When the counts started, large numbers were counted already in October, but autumn numbers steadily decreased as the geese stayed further north in Sweden. The January counts on the other hand increased as the geese wintered in Scania in successively larger numbers rather than leaving Sweden. In January 2017, more than 40,000 or two-thirds of the global population of Taiga Bean Goose were counted in Scania. Within the province, more and more geese concentrated to inland areas and instead of using the Öresund coastal region as in earlier years. Birds from different breeding areas, e.g. from Finland and Sweden, used different parts of Scania. In recent years 3000–9000 of Tundra Bean Geese Anser f. rossicus have been wintering in a small area in northeast Scania.
Migration of Greylag Geese Anser anser according to recoveries of birds marked with traditional leg-rings in Sweden
Authors: Nilsson Leif
Published: April 2019

Traditional recoveries of ringed Greylag Geese Anser anser from different regions in Sweden have been analyzed to compare the migration patterns from a number of different areas. During the years up to and including 2012, 7,210 Greylag Geese were marked with metal rings from the Swedish Ringing Centre, yielding 1398 recoveries. After exclusion of local recoveries in the ringing area, 924 recoveries were used in the present analysis. The majority of recoveries were from the Western European ﬂyway along the Atlantic coast but some Greylag Geese marked in the province of Södermanland migrated south through Eastern Europe even reaching Northern Africa. A number of records of Greylag Geese marked during the moult on Gotland were probably recruited from Eastern Europe. Later about 25% of these birds migrated south through central Europe. In general, the geese marked in different parts of the country showed the same migration patterns as geese neck-banded in SW Scania and Södermanland.
Flock-fishing deep-diving piscivores (Great Crested Grebe Podiceps cristatus, Great Cormorant Phalacrocorax carbo, Common Merganser Mergus merganser) at Lake Vombsjön, southern Sweden, and those that exploit them
Authors: Källander Hans
Published: April 2019

Lake Vombsjön in southern Sweden is visited by large numbers of Great Crested Grebes Podiceps cristatus (>2000), Great Cormorants Phalacrocorax carbo (sometimes >1000) and Common Mergansers Mergus merganser (up to 2000) in late autumn and early winter. Different species exploit them. Great Crested Grebes are used especially by commensal Common Gulls Larus canus; the gulls take advantage of fish that flee towards the surface. Common Gulls also use cormorants and mergansers in the same way but also try to kleptoparasitize them. Both Herring Gulls Larus argentatus and Great Black-backed Gulls Larus marinus kleptoparasitize these two species, while Red Kites Milvus milvus, Grey Herons Ardea cinerea and Carrion Crows Corvus corone use them commensally. White-tailed Eagles Haliaeetus albicilla seem to use both methods to obtain fish. On 50% of one hundred visits during November to March, eagles were seen flying low over the fishing flocks. They would fly a metre or so above the flocks and then accelerate and attack a bird holding a fish. The bird would then either try to escape by a rush or by diving, dropping the fish which the eagle seized. Interestingly, the flock-fishing birds showed no fear reactions towards the eagles but appeared to regard them similarly to large gulls.
Changes in migration and wintering patterns of Greylag Geese Anser anser from southernmost Sweden during three decades
Authors: Nilsson Leif , Kampe-Persson Hakon
Published: April 2019

The recent increase of the Greylag Goose Anser anser population has caused complaints about crop damage. In response to this, the Nordic Collegium for Wildlife Research started a neck-banding program to elucidate the migration and movement patterns. During 1984–2009, 2,639 Greylag Geese were marked in a breeding area in SW Scania, southernmost Sweden. Up to and including 2012, 15,296 re-sightings were reported from outside the breeding area (in addition to more than 100 000 from the breeding area). In the early years of the study, the majority of the geese migrated to winter in southernmost Spain, staging in The Netherlands. In later years, hardly any individuals migrated to Spain, the majority staying in The Netherlands with an increasing proportion wintering in southern Sweden. From 1986 to 2017, the mean latitude for re-sightings changed ten degrees to the north. About 13% of the geese changed winter quarters between two consecutive winters. Moreover, the southward migration occurred much later in the autumn and the geese returned to the breeding areas about one month earlier in spring.
Strong decrease of waders Charadrii in central southern Sweden during the last 50 years
Authors: Nilsson Sven G
Published: April 2019

The number of territories of waders were counted in an area of 460 km2 around 56°37'N; 14°20'E. The most important breeding sites for waders were closely monitored in several years, 1969–1981 and again 2015–2018. Most species declined strongly, with the exception of Charadrius dubius which colonized exploited peat bogs without vegetation and open man-made gravel surfaces. Some mires were drained in the ﬁrst study period, which can explain up to 20% of recorded population declines of some species (Pluvialis apricaria, Numenius arquata, Tringa glareola). Other likely causes are earlier hay harvest and with different methods. Abandonment of cattle grazing of pastures on many small farms also occurred between the study periods. Several wader species forage on wet pastures. Predation on small young of waders may have increased. The crane Grus grus has increased dramatically in the study area and small young of waders most likely is part of the food of cranes. Changes at foraging sites during migration and in winter may be contributing causes of wader declines as well as climate change.

Published: April 2019

The subject of the study are the features of the Russian-speaking
community of the State of Israel. The author examines such aspects of the topic
as: the nature of the community ties that are formed among the Russian-speaking
Israelis and the status of the Russian language in Israel. An attention is also
paid to the factors that contributed to the formation of a unique identity of
the representatives of the «Russian Israel», to the main stages of the evolution of the Russian-speaking community
in the political life of Israel and to the formation of the Russian media
space. The Russian-speaking community is rightfully regarded as a long-term
phenomenon, which is currently an important player in the political arena of
the country. The novelty of the study is the implementation of a comprehensive
analysis of the phenomenon of the «Russian Israel» on the basis of original sources. The main conclusion of the study:
the territorial localization, the preservation of the cultural environment of
the country of origin, the special status of the Russian language in Israel and
its place in the media space, the maintenance of the community symbols of
different nature, the program of socio-political development became the factors
of the unification of the Russian-speaking community of Israel.
İsrail'de Dini Yahudi Terörizmi
Authors: KURT Menderes
Published: April 2019

Genel olarak dini terörizm denildiğinde ilk akla gelen
“İslami” terörizm olmaktadır. İslam ile özdeşleşen bu olgunun tikel olmadığını,
başka dini topluklarında dini söylemler üzerinde terörizme başvurduğu ve yine
dini söylem üzerinden terör eylemlerini meşrulaştırdığı görülmektedir. Bunun en
iyi örneklerinden bir tanesi ise Dini Yahudi Terörizmidir. İslami radikal terör
örgütlerinin düşüncesine nispeten benzeyen Dini Yahudi Terörü, özellikle 1977’den
itibaren İsrail’de sağın iktidarı ile güç kazanmıştır. Dini Yahudi Terörü,
Teritoryal bir hakimiyet yani Eretz Israil üzerinde tam hak iddiasından
güç alan, Yahudi olmayanlara karşı, özelliklede Araplara, sert bir tutum
takınan, Araplara karşı her türlü şiddet eylemini meşru olarak gören ve Yahudi
dini yasası olan Halakha’ya atıfla terör eylemlerini meşrulaştıran, Mesiyanizm
ve Yahudi kurtuluşunu hedefleyen bir yapıya sahiptir. Bu çerçevede uzun bir
süre Filistinlilere karşı terör eylemlerine gerçekleştirilmiş ve çeşitli
örgütler kurulmuştur. Fakat literatürde bu örgütler ve eylemleri hakkında fazla
bir bilgi bulunamamaktadır; ya devletin kuruluşunda etkili olan terör
örgütlerinin ya da diğer dini terörizm hareketlerinin gölgesinde kalmaktadır.
Bu nedenle bu çalışma, İsrail’de Dini terörizmin kökenleri, doktrini, meşruiyet
söylemleri, etkinliği, adam devşirme yöntemleri gibi sorunsalları ele
almaktadır. Bununla birlikte bu sorunsalları Dini Yahudi Terörizm’in zirve
yaptığı el-Halil saldırısı ve Rabin suikastını gerçekleştiren “teröristler”
üzerinden değerlendirmeyi hedeflemektedir.

The Example of decision analysis in choosing a surface type
for constructing a segregated cycle facility and footway in a recreational area
Authors: Szczuraszek Paweł
Published: April 2019

In the article the author present a proposed method of assessing different types of segregated cycle facility and footway surfaces basing on criteria decision analysis. Subsequently, surface types most commonly used in Europe as well as around the world were chosen and compared basing on the previously established criteria regarding functional, technical and economical characteristics. Further on, an optimal surface type was chosen for a specific segregated cycle facility located in a landscape park with unfavourable groundwater conditions. Similarly, an optimal surface type for footways was chosen. Basing on the reliable results of the analyses, the author formulated conclusions which can be helpful in choosing the appropriate surface type for segregated cycle facilities and footways in different but similar projects.

Classification of soil-steel structures due to shell deformation changes during backfilling
Authors: Machelski Czesław
Published: April 2019

Soil-steel structures made of corrugated sheets are divided into two groups in the paper. This division results from the critical situations caused by flexural stresses (bending stresses) in shells. One of them occurs in the stage of construction, during backfilling – index of uplift ω is then controlled. The other situation is more difficult to be identified as it occurs in the exploitation phase. The possibility of its occurrence is evident in the final stages of construction, which is indicated by the index of deflection change η. Specific examples of both shell groups are analysed in the paper. A relationship between shell crown deflection and normal stress determined in the work in a geometrical form – as a change of curvature – is used to evaluate the structural safety. Usefulness of basic surveying techniques, available during construction, is indicated in the calculation examples. They allow assessing the shell safety on the basis of the shell crown zone deformation.
