Europe and the EU have been facing many crises and challenges in recent years.From Brexit and rising nationalism to economic problems and unanimous refugee policies,most of them remain unsolved.Instead of moving forward with the European integration project,Europe seems to regress in many instances.Considering this turmoil,it seems all the more important to historicize the affirmative discourse of Europe and to expand the knowledge of the European unification process with novel insights into its history.Only if a broad understanding of its roots and developments prevails,the conflicts of the present can be better evaluated and addressed.Particularly one set of so far neglected sources from Europe’s past serves as guiding light in that respect:the early modern Europe literature written in the Latin language.Between 1400 and 1800,Latin enjoyed a similar status in promoting scientific discoveries,negotiating political affairs and generally communicating on an international level as modern-day English.By offering a brief glance at some historically influential Latin texts from the early modern discourse of Europe,this article will show that the early modern European crises strikingly resemble Europe’s current crises despite the difference in political,social,and economic circumstances.The discourse of Europe has from the beginning been a stable discourse,characterized by the same recurring questions for centuries.When used as reference point for the crises of the 21st century,the prospects for the European integration look better than presumed. 展开更多

Anthropogenic Nitrogen oxides(NO_(x)=NO_(2)+NO)emissions are highly concentrated in urban area,and the weekly cycles,seasonal patterns and long-term trends of tropospheric NO_(2) columns over cities differ from region to region due to different emission sectoral compositions and human activities.In this study,we used satellite observed tropospheric NO_(2) column data to compare the longand short-term NO_(2) column density time series over cities in the United Sates(the U.S.),western Europe and China.The results showed that in all the targeted cities,the outbreak of the Corona Virus Disease in 2019(COVID-19)moved the December peak of the city-level NO_(2)columns forward to November and October or even earlier in 2020 and 2021.On weekly level,cities in the U.S.show the lowest NO_(2) columns ratio on weekend/work day,then come the western European cities,and a weak weekly pattern is seen in Chinese cities.For all the cites,we find a higher weekend/work day NO_(2) ratio in cold seasons than in warm seasons,indicating a higher contribution from NOx emission sectors of residential,industry and power plants in the warm seasons.In the long-term,NO_(2) columns over the U.S.and western European cities declined by a fraction twice that of the regional mean level from 2004 to 2021.In China,NO_(2) columns started to decrease since 2012,at a similar rate between the city and regional level.This work confirms the importance to quantify and control NOx emissions from cities. 展开更多

Steep-slope cropland plays a vital role in food production,economic development,ecosystem diversity,and Eu-ropean cultural heritage.However,these systems are susceptible to extreme weather events.The 2022 summer drought significantly impacted European agriculture,but the specific effects on steep-slope crops remain uncer-tain.Clarifying this is essential for comprehending similar future events and for implementing effective water management strategies to ensure the sustainability of steep-slope agriculture and associated ecosystem services.This study quantitatively analyzes the spatial distribution of twelve major European steep-slope(>12%)crops and assesses agricultural drought severity during the 2022 events using open-access spatial data.The satellite-based Vegetation Health Index(VHI)is utilized to identify critical hotspots.Results show that olive grove is the most widespread crop in steep slope agriculture(34%of total area),followed by wheat(24%),maize(16%),and vineyard(11%).Almost half of the steep-slope agriculture in Europe suffered drought during summer 2022.Vineyards were hardest affected at 79%,primarily in northern Portugal,northern Spain,southern France,and central Italy.Sunflowers followed at 62%,mainly in Spain,central Italy,southern France,and northern Roma-nia.Olive groves ranked third at 59%,with the most impact in northern Portugal,southern and central Spain,and southern Italy.Maize was also significantly affected at 54%.In this paper,we therefore highlight the need to increase steep-slope agriculture resilience by improving water management and promoting sustainable land practices. 展开更多

Concurrent extreme weather events in geographically distant areas potentially cause high-end risks for societies.By using network analysis,the present study managed to identify significant nearly-simultaneous occurrences of heatwaves between the grid cells in East Asia and Eastern Europe,even though they are geographically far away from each other.By further composite analysis,this study revealed that hot events first occurred in Eastern Europe,typically with a time lag of3-4 days before the East Asian heatwave events.An eastward propagating atmospheric wave train,known as the circumglobal teleconnection(CGT)pattern,bridged the sequent occurrences of extreme events in these two remote regions.Atmospheric blockings,amplified by surface warming over Eastern Europe,not only enhanced local heat extremes but also excited a CGT-like pattern characterized by alternative anomalies of high and low pressures.Subsequent downstream anticyclones in the middle and upper troposphere reduced local cloud cover and increased downward solar radiation,thereby facilitating the formation of heatwaves over East Asia.Nearly half of East Asian heatwave events were preceded by Eastern European heatwave events in the 10-day time range before East Asian heatwave events.This investigation of heatwave teleconnection in the two distant regions exhibits strong potential to improve the prediction accuracy of East Asian heatwaves. 展开更多

The aim of the article is to analyze the impact of interest groups on the Europe 2020 Strategy. One of the basic assumptions of the author is to present its analysis of the public consultation on the Europe 2020 strategy and its impact on the development of the European Union. The European Union needs to stimulate the economic integration of its particular Member States and the assumed postulates will strengthen its global position. The goal is to create a strong economy, based on modem technologies and knowledge, which would be able to compete with the healthiest economies in the world. The main intention of the author of this article is to find answers to the foUowing research questions: Did the interest groups have or do they still have any considerable influence on the strategies implemented in the European Union? To what extent do they contribute to the process of reforming the Europe 2020 strategy through consultations within the framework of the European Union? Are their lobbying activities efficient enough to allow for the perception of interest groups as significant players, capable of influencing the course of consultations on the Europe 2020 strategy? What kind of external factors make it possible for the interest groups to influence the consultations? To what extent are business groups capable of influencing particular institutions in the course of consultations on the Europe 2020 strategy? What does their activation in relation to these institutions depend on? 展开更多

[Objective] The objective was to research the quality evaluation of Chinese wheat variety which analyzed in Europe laboratory, discuss the quality analysis standard of different countries. [Method] Two leading varieties (Yangnong19, Jimai22) of Huanghuai wheat area from China were analyzed in Cra-w (Walloon Agricultural Research Centre). [Result] Yannong19 corresponds to amuchstronger flour with a far better gluten quality. It could be used for bread making. It could also be used to produce good quality gluten. Jimai22 is not suitable for bread making but would probably be better for noodles production. [Conclusion] Protein results which come from NIR instrument are over estimating the content. This is probably due to the fact that Europe instruments are calibrated with European wheat. 展开更多

The territory of the Balkan Peninsula in SE Europe is reviewed, from the point of gemmology, as the cradle of gem and decorative minerals and metals in European prehistory. During the local Neolithic period (end of 7 th -6 th millennium BC), as material for tools or for beads, nephrite (with the earliest known Balkan nephrite culture), jadeite-omphacite and quartz (different varieties) were introduced to make pendants and idols. Large quantities of copper and gold artifacts are known since the Chalcolithic period (5 th millennium BC)(unique for the region;the largest in number of gold artifacts is the Varna I Chalcolithic necropolis in Bulgaria). The gemmological materials in the Balkans are known for malachite, antigorite serpentinite, turquoise, rock crystal, carnelian, jasper, jet and obsidian. In the Varna I necropolis (mid 5 th millennium BC) are recorded the first known complex faceted carnelian beads with 32 facets, as well as some of the most important gemmological techniques and procedures such as faceting, tumbling, annealing, miniaturization and standardization. As pigments for pottery, cinnabar, graphite and gold were used in different prehistoric sites. The earliest salt production in the Balkans is known from sites in Romania and Bulgaria, and because of its trade, salt is positively linked to a population rich with prestigious goods. The introduced possible Chalcolithic weight unit “van”(2 carats) is supposed to be the earliest known in prehistoric times. 展开更多

His earlier theoretical work did not revisit the idea in any distinct manner. Moral Consciousness, I argue, has traces of a legal identity and universal morality. While interpreting Kohlberg's work, Habermas did not seek to tie the concept of citizenship or political identity into his account of Moral Consciousness. The concepts of political identity and a legal orientation come up, more recently and in a clearly observable manner, in Habermas's writings on Europe. His writings and speeches delivered on the idea of Europe before the Eurozone crises as well as those published and delivered after the crises refer to a strong sense of Constitutional Patriotism understood in the European sense. It is this idea that I would like to dwell on in this paper. 展开更多

The European Union has been experiencing the whole set of serious crises undermining European integration. The most important ones have been: financial and economic crisis, immigration crisis, crisis of nationalistic radicalization, Brexit, crisis of security caused by terrorism, strengthening of the Islamic State (ISIS), and destabilization of regions around Europe (mainly in the Middle East). The main thesis of this article is that all of them have weakened not only the EU as a whole but also the Member States. This has caused serious consequences being the main topics of this analysis, namely, (1) the value of solidarity lying upon the European integration concept being challenged by the crises; and (2) undermining by the crises the EU's pursuit of achieving the competitive advantage, stated in the strategy Europe 2020. The lack of solidarity is strongly visible in the EU Member States' differentiated attitudes towards the crises the EU has been facing. The paper will focus on analysis of solidarity in the light of intergovernmental approach supported by constructivism. The main research questions are: (1) To what extent have the EU crises strengthened the intergovernmental approach in the EU integration? (2) How has the meaning and scope of the solidarity as the main EU value changed over time in the EU's citizens perception due to the EU crises? (3) To what extent have strong intergovernmental approach and instrumentalization of the solidarity value influenced pursuit for competitive advantage in the EU? (4) Does solidarity have a potential to contribute to efficient reform of the EU leading to strengthening its striving for competitive advantage in the future? The main research approach is intergovernmentalism while the dominating methods are a process-tracing supported by a systemic method. The main conclusion of the article is necessity for redefining the rule of solidarity in order to efficiently strive for competitive advantage. 展开更多

Prostate cancer(PCa)is the second most common cancer among men worldwide and even ranks first in Europe.Although Asia is known as the region with the lowest PCa incidence,it has been rising rapidly over the last 20 years mostly due to the introduction of prostate-specific antigen(PSA)testing.Randomized PCa screening studies in Europe show a mortality reduction in favor of PSA-based screening but coincide with high proportions of unnecessary biopsies,overdiagnosis and subsequent overtreatment.Conclusive data on the value of PSA-based screening and hence the balance between harms and benefits in Asia is still lacking.Because of known racial variations,Asian countries should not directly apply the European screening models.Like in the western world also in Asia,new predictive markers,tools and risk stratification strategies hold great potential to improve the early detection of PCa and to reduce the worldwide existing negative aspects of PSA-based PCa screening. 展开更多

Recently, the desiccation effect of the North Atlantic Oscillation(NAO) is found to be positively correlated with violent conflict in pre-industrial Europe, with agricultural shrinkage and its subsequent economic shocks to be their causal link. However, it remains unexplored whether the correlation persists if the study period is extended backward in time, a different definition of violent conflict is applied, or the relationship is examined at lower geographic levels. In this study, we based on 835 internal disturbance incidents in Europe during 1049–1800 to conduct long-temporal and multi-scalar examination on the NAO-conflict nexus. ′Time-series′ and ′panel data′ disaggregation approaches, together with Granger Causality, Multiple Regression, and Survival Analyses were applied to verify the nexus quantitatively. Results show that the positive NAO-conflict correlation was significant at the continent and physiographic zone levels. During the positive NAO phases, the annual probability of internal disturbance outbreak increased by 70.0% in the southern Europe and the Mediterranean, a zone most affected by the NAO-induced desiccation effect. Yet, the NAO-conflict correlation was rather inconsistent when it was downscaled to the sub-regional level. Moreover, the NAO-conflict correlation was inflated under the time-series approach, while the panel data approach demonstrated the region-specific nature of the NAO forcing more clearly. The associated implications in examining climate-conflict nexus are discussed. Our findings may be crucial in examining violent conflict in the northwestern Africa, a highly agricultural region affected by the NAO. 展开更多

Defining the spatial extent of mountain areas has long been a challenge. In the present century, the availability of digital elevation models(DEMs) incorporated into geographic information systems(GIS) has allowed the definition of mountain areas based on topographic and other criteria. This paper presents the various delineations of mountains that have been prepared at three scales – global, regional(Europe), and national – and explores the reasons and processes leading to these delineations, and how they have been used. A detailed case study is then presented for Norway. Overall, two types of approaches to mapping mountains have been taken: first, considering mountains per se, based on elevation and/or topography; second, considering them among other categories, e.g., landforms or biogeographical, environmental or landscape zones. All attempts to map mountain areas derive essentially from the objectives of those commissioning and/or undertaking the work; a unitary definition remains unlikely. 展开更多

The significance of hepatitis E virus(HEV)as an important public health problem is rising.Until a decade ago,cases of HEV infection in Eur-ope were mainly confined to returning travelers,but nowadays,hepatitis E represents an emerging zoonotic infection in many European countries.The aim of this manuscript is to perform a systematic review of the published literature on hepatitis E distribution in humans,animals and environmental samples("One Health"concept)in the South-Eastern European countries.Comparison of the available data showed that the anti-HEV seroprevalence in the South-Eastern Europe varies greatly,depending on the population studied,geographical area and methods used.The IgG seroprevalence rates in different population groups were found to be 1.1%-24.5%in Croatia,up to 20.9%in Bulgaria,5.9-%17.1%in Romania,15%in Serbia,up to 9.7%in Greece and 2%-9.7%in Albania.Among possible risk factors,older age was the most significant predictor for HEV seropositivity in most studies.Higher seroprevalence rates were found in animals.HEV IgG antibodies in domestic pigs were detected in 20%-54.5%,29.2%-50%,38.94%-50%and 31.1%-91.7%in Serbia,Bulgaria,Romania and Croatia,respectively.In wild boars seroprevalence rates were up to 10.3%,30.3%and 31.1%in Romania,Slovenia and Croatia,respectively.A high HEV RNA prevalence in wild boars in some countries(Croatia and Romania)indicated that wild boars may have a key role in the HEV epidemiology.There are very few data on HEV prevalence in environmental samples.HEV RNA was detected in 3.3%and 16.7%surface waters in Slovenia and Serbia,respectively.There is no evidence of HEV RNA in sewage systems in this region.The available data on genetic characterization show that human,animal and environmental HEV strains mainly belong to the genotype 3. 展开更多

Background: European forests are considered a crucial resource for supplying biomass to a growing bio-economy in Europe. This study aimed to assess the potential availability of forest biomass from European forests and its spatial distribution. We tried to answer the questions(i) how is the potential forest biomass availability spatially distributed across Europe and(ii) where are hotspots of potential forest biomass availability located?Methods: The spatial distribution of woody biomass potentials was assessed for 2020 for stemwood, residues(branches and harvest losses) and stumps for 39 European countries. Using the European Forest Information SCENario(EFISCEN) model and international forest statistics, we estimated the theoretical amount of biomass that could be available based on the current and future development of the forest age-structure, growing stock and increment and forest management regimes. We combined these estimates with a set of environmental(site productivity, soil and water protection and biodiversity protection) and technical(recovery rate, soil bearing capacity) constraints, which reduced the amount of woody biomass that could potentially be available. We mapped the potential biomass availability at the level of administrative units and at the 10 km × 10 km grid level to gain insight into the spatial distribution of the woody biomass potentials.Results: According to our results, the total availability of forest biomass ranges between 357 and 551 Tg dry matter per year. The largest potential supply of woody biomass per unit of land can be found in northern Europe(southern Finland and Sweden, Estonia and Latvia), central Europe(Austria, Czech Republic, and southern Germany),Slovenia, southwest France and Portugal. However, large parts of these potentials are already used to produce materials and energy. The distribution of biomass potentials that are currently unused only partially coincides with regions that currently have high levels of wood production.Conclusions: Our study shows how the forest biomass potentials are spatially distributed across the European continent, thereby providing insight into where policies could focus on an increase of the supply of woody biomass from forests. Future research on potential biomass availability from European forests should also consider to what extent forest owners would be willing to mobilise additional biomass from their forests and at what costs the estimated potentials could be mobilised. 展开更多

Identifying tree locations is a basic step in the derivation of other tree parameters using remote sensing techniques, particularly when using airborne laser scanning. There are several techniques for identifying tree positions. In this paper, we present a raster-based method for determining tree position and delineating crown coverage. We collected data from nine research plots that supported different mixes of species. We applied a raster-based method to raster layers with six different spatial resolutions and used terrestrial measurement data as reference data. Tree identification at a spatial resolution of 1.5 m was demonstrated to be the most accurate, with an average identification ratio (IR) of 95% and average detection ratio of 68% being observed. At a higher spatial resolution of 0.5 m, IR was overestimated by more than 600%. At a lower spatial resolution of 3 m, IR was underestimated at less than 44% of terrestrial measurements. The inventory process was timed to enable evaluation of the time efficiency of automatic methods. 展开更多

This study provides characteristics of aerosol columnar properties,measured over ten countries in Eastern Europe from 2002 to 2019.Aerosol optical depth(AOD)and Angstrom exponent(AE)were obtained with the Moderate Resolution Imaging Spectroradiometer(MODIS)Collection 6.1 merged Dark Target and Deep Blue aerosol product.The product is validated using ground-based Aerosol Robotic Network(AERONET)situated at Minsk,Belsk,Moldova and Kyiv.The results showed that 76.15%of retrieved AOD data are within the expected error.It was established that 64.2%of AOD points are between 0 and 0.2 and 79.3%of all AE points are over 1.Mean AOD values in the region vary from 0.130±0.04(Moldova)to 0.193±0.03(Czech Republic)with mean value in the region 0.162±0.05.Seasonal mean AOD(AE)values were at the maximum during the summer from 0.231±0.05(1.482±0.09 in winter)to minimum 0.087±0.04 during the winter(1.363±0.17 in summer).Gradual AOD reduction is observed in all countries with annual trend from-0.0050(Belarus)to-0.0029(Russia).Finally,the relationship between AOD and AE was studied to classify various aerosol types and showed seasonal non-uniformity of their contribution depending on variation in sources.The entire region is under significant impact of various aerosol types,including clean continental(CC),mixed(MX)and anthropogenic/burning(AB)aerosols types that are at 59.77%,24.72%,and 12.97%respectively.These results form an important basis for further regional studies of air quality and distribution of sources of pollution. 展开更多
