Study of Consequent Damage of Metal Pivotal Structure on Maintenance in Polluted Surroundings

Author(s): Jurate Mockiene,Valerijus Keras,Gintaris Cinelis / Language(s): English Issue: 4/2016

The paper is related with tends to elucidate various forms of harm generated by space pollution to economy of the region in context of the ideas of Agenda 2000 etc. The study discusses the data of the air pollution and subsequences of damages that are fixed in elements of high-rise metal structures. It adduces some data of factual pollution that is dangerous to high-rise metal structures, location of initial generators of pollutants, interrelations of polluted flows during their migration in the air. Experimental observation reveals the accumulation of micro and local defects, and their joining process. Afterwards aftereffects are discussed as stress concentration around defects, wear and tear of structures, the scattering of strength resources, loss of the durability of single element and the structure in whole. The residual strength of steel elements of structure was tested using standard specimens that had been cut out from the elements of structure at the end of its exploitation.

The Influence of Aluminum Hydroxide (Al(OH)3) Additive on the Physical and Mechanical Properties of Alkali–Activated Slag

Author(s): Danutė Vaičiukynienė,Janavičius Eugenijus,Kielė Andrius,Parthiban Siddeshwaran,Aras Kantautas / Language(s): English Issue: 4/2016

Alkali activation is a highly active and rapidly developing field of activity in the global research. Alkaliactivated cements have found a variety of applications: transportation, industrial, agricultural, residential, mining and so on. Alkali activated binders are made by mixing industrial aluminosilicate waste materials such as one of them is slag. This study aims to evaluate the influence of incorporating aluminum hydroxide on the physical and mechanical properties of alkali-activated slag. Mineralogy of composites were studied using X-ray diffraction analyze. The results showed that the molar ratio of raw materials strongly affects the kinetics of reaction and the structural evolution of the solid phases forming in alkali silicate activated binders. The role of Al(OH)3 in the mixtures in activated binders is closely related to the availability of Al in the system, because it controls the concentrations of secondary products such as zeolites. Based on the experimental results, it can be concluded that by reducing Al2O3 from 1.30 mol till 0.75 mol (in the mixtures of raw materials) the compressive strength of samples increases from 27 - 42 MPa till 39 - 54 MPa.

Influence of Recycled Concrete Dust on the Properties of Self– Compacting Concrete (SCC)

Author(s): Ernestas Ivanauskas,Lazauskas Mantas,Grigaliūnas Paulius / Language(s): English Issue: 4/2016

Concrete – composite material which economical effect mostly depends on the amount of binder material (usually cement), its type and fineness. Cement manufacturing generates great employment of energy resources. The demand for all kind of manufacturing natural resources are aimed to be reduced as much as possible. Alternativeraw material resources are being introduced and tested together with increasing self-compacting concrete (SCC) popularity in Lithuania. Considering environmental requirements to reduce environment pollution according to ES 305/2011 regulation and importance of economic benefits it is aimed to investigate recycled concrete influence for self-compacting concrete durability properties. Assessing one of the main mechanical concrete property – compressive strength up to 1 year concrete hardening duration, it was observed, that replacing cement by concrete dust, practically no negative influence was observed. In some cases this replacement even improves concrete compressive strength (10 % concrete dust), except greater amount of additionally grinded concrete dust. In our case it was noticed, that replacing up to 10 % cement by concrete dust from 1.85 % to 2.09 % increases concrete closed porosity and predicted concrete resistance to freeze-thaw cycles increases up to 30 %. It allows to expect positive test results while real test would be carried out on the basis of Lithuanian standard LST 1428.17.

У сусрет прекограничном резервату биосфере „Мура–Драва–Дунав”

Author(s): Miloš Petrović / Language(s): Serbian Issue: 147/2014

At ministry assembly in Budapest in March 2011, republics such as Austria, Slovenia, Hungary, Croatia and Serbia, were signatories of common Declaration on the preparation of the establishment of the ”Mura – Drava – Danube Transboundary Biosphere Reserve”(MDD-TBR). Even though this document does not have obligatory character for states that signed it, this declaration represents the obvious course these states will follow in order to improve their cooperation. Beside political, economic, cultural and other well developed forms of cooperation, a multilateral cooperation emerges within the areas of conservation, protection and improvement of flora and fauna of the Danube and rivers Drava and Mura that belong to The Danube River Basin. In this article the author provided a short review of basic international legal documents that refer to Biosphere Reserves regarding specifically the overall Danube Strategy by European Union and belonging Action Plane to Danube Strategy. The author analyzed the paramount clauses of Declaration MDD – TBR, with intention to reveal this little known document to scientific and professional public. In that sense, the principles for selecting the actual biosphere reserve have become a priority as well as the elemental objectives a biosphere reserve should accomplish and its spatial organization.

Vodozemci iz okoline Gračanice

Vodozemci iz okoline Gračanice

Author(s): Avdul Adrović,Muhidin Mujić / Language(s): Bosnian Issue: 21/2006

Živi svijet obiluje raznovrsnim životnim oblicima, koji na svojstven način odražavaju funkcioniranje biosfere kao integralne cjeline. Toj raznovrsnosti na specifičan način doprinose i vodozemci kao evolutivno najniži kopneni kičmenjaci. Vodozemci su najmalobrojnija skupina recentnih kopnenih kičmenjaka, ali uprkos tome, u našoj zemlji su relativno slabo istraženi. Počeci proučavanja vodozemaca na prostoru naše zemlje vezuju se za drugu polovicu 19. i početak 20. stoljeća i za imena stranih istraživača. Prve relevantne i naučno koncipirane rezultate istraživanja ove grupe životinja u našoj zemlji objavio je Werner (1893., 1897.), te Reiser (1895.). Naročit doprinos u istraživanju vodozemaca Bosne i Hercegovine u tom periodu vezuje se za Bolkay-a (1919., 1922., 1924.).

Екофеминизам као начин решавања неких еколошких питања

Екофеминизам као начин решавања неких еколошких питања

Author(s): Dragana Ćorić / Language(s): English Issue: 148/2014

Women and nature are connected in many different ways: with their biological status, reproductive role, discrimination. That is why ecofeminism stands for one of the main theoretical, philosophical and even practical ways of resolving the environmental problems. The representatives of this thinking find that changing positions and behaviors by leaving the patriarchal approach to everything – to the women and to the nature, can stop the degradation of the environment.Demographic significance of the women’s role, in context of environmental changes, was represented by some feminist movements, as Chipko movement in India, Green Belt movement in Kenya, Love Canal in State of New York, etc. In this paper, the author gives a short overview of connections between women and nature, and proposes some new solutions.

Dung beetles and their role in the nature

Author(s): Adam Byk,Jacek Piętka / Language(s): English Issue: 1/2018

Scarabaeoid beetles (Scarabaeoidea) inhabit all zoogeographical regions of the world. However, coprophagy as the type of nutritional specialization dominates among the scarabaeoid beetles. Te number of dung beetles (coprophagous Scarabaeoidea) is estimated at about 7,000 species. There are about 460 of dung beetles species in Europe, and about 90 of dung beetles species in Poland.Dung beetles can be endocoprids (dwellers), paracoprids (tunnelers) or telecoprids (rollers). Endocopric species lay eggs directly into the dung, paracropic species dig earth tunnels of various lengths ending with brooding chambers beneath the dung, and telecopric species separatea portion of dung and roll it into round balls which are then transported, sometimes far from the original source of the dung, to a place where the beetles dig tunnels ending with brooding chambers. Such a variety of methods of using faeces by dung beetles cause an accelerated circulation of nutrients, increased soil aeration, plant spreading, and a reduction in the number of parasites (flies and nematodes). Among dung beetles presently encountered in Poland there are endocopric and paracopric species

Greening Economies: A Normative Challenge in International Relations

Greening Economies: A Normative Challenge in International Relations

Author(s): Miroslav Stevanović,Dragan Đurđević / Language(s): English Issue: 4/2017

In this article, we examine the concept of “greening economy” from the aspect of the interest of States as actors in international relations responsible for providing vital values of political communities. The problem in this context primarily involves the nonexistence of consensus about either normative or value content of the “greening economy”, apart from a commonly acceptable discourse on the practical level. Nevertheless, such discourse has not been functionalised through new developments in instruments and mechanisms of administration, governance and validation of efforts in numerous sectors at the international level. On the methodological level, the basic dichotomy between the practical and perceptive in the concept of greening economy has imposed a need for phenomenological approach in estimating its functional roles. In this segment, we pursued the obvious appearance or impacts in practice, regardless of the narratives. As far as the discourse itself is concerned, this analysis did not require a detailed insight into perception since different bodies and states apply the concept as they find suitable for their purposes. In the structural analysis, since the greening of economy, as a concept, introduces series of bodies and institutional procedures dealing with measurements, criteria, indicators and tools that impose administering on a supranational level, we have focused on the context of the globalisation process. Besides, these indicators mostly do not lead to the projected goals, nor affect the economy as a whole and achieving sustainable development goals. We find that mainstreaming the environment into economic development, through 'green economy', regardless of how logical in substance it may be, is still no more than an emerging theoretical discourse, which is suitable for the needs of globalisation. We thus conclude that “greening” is a contemporary political economy, which deals with unsustainability on the production level, and lacks a clear definition of development. This concept promotes an administrating process on the global level, without legal grounds, which is a challenge for national security, given that national authorities should be responsible for sustainable development, as a vital value.

Mavi Okyanus Stratejisi: Dünyadan ve Türkiye’den Örnekler

Mavi Okyanus Stratejisi: Dünyadan ve Türkiye’den Örnekler

Author(s): Süleyman Ağraş,Fırat Atbaş,Enes Şeyba / Language(s): Turkish Issue: 2/2017

Competition is at the center of much debate on how to explain the nature of today's economic rules. The nature of the competition varies depending on the characteristics of the industrial environment, the competitive attitudes of the firms and the economic conditions of countries. One of the competitive approaches is to see competition as "meaningless". In this study, Blue Ocean Strategy (Blue Ocean Strategy), which proposes competitive advantages to companies struggling in competition and emphasizes leaving behind competition, was evaluated in terms of strategy development paradox. The study also was focused on examples of the blue ocean strategy through examples from the world and Turkey.

SÜRDÜRÜLEBİLİR TURİZM AÇISINDAN KIZILIRMAK DELTASI KUŞ CENNETİNİN YEREL PAYDAŞLAR TARAFINDAN DEĞERLENDİRİLMESİNE YÖNELİK BİR ARAŞTIRMA

Author(s): Mehmet Vatansever,Orhan Batman,Aysu Altaş / Language(s): Turkish Issue: 2/2017

Tourism is an industry that has started to rise rapidly in recent years. Thus, there has been a tendency towards different tourism types rather than mass tourism in order to spread tourism on every day of the year. By this way, there has been an increasing interest in the developing alternative tourism types and these tourism types have started to be evaluated within the frame of sustainability. Alternative tourism types increase people’s interest in unexplored natural environments and make these regions a destination, which has brought up the issue of protecting the regions and realizing tourism activities there. As long as tourism activities in these regions are carried out within the scope of eco-tourism; the richnesses and natural diversity of the regions will be protected and the local people will develop socioeconomically. This study examines all the richnesses and potential tourism types in Bird Sanctuary on the Kızılırmak Delta and includes the opinions and suggestions of relevant shareholders regarding the problems of the region. Semi-structured interviews were conducted with relevant shareholders and their opinions about the tourism supply and sustainability of the region were received. As a result of the study, it was determined that available touristic and social facilities in the region were inadequate, infra and super structures in the region needed to be developed and a greater importance had to be attached to advertising activities. In addition, it was concluded that shareholders were highly positive and excited about protecting the beauties of the Kızılırmak Delta and providing its sustainability by including the delta in the permanent heritage list of UNESCO

Утицај термоелектрана на животну средину и могући правци заштите

Author(s): Gojko Deretić / Language(s): Serbian Issue: 3-4/2017

Environmental awareness of citizens is still low, it is necessary to pay more attention to education and solving problems of pollution of water, air and soil. If all of developmental potential was focused on environmental protection and the environment in which citizens live, there would be a reduction in harmful effects in population. A large number of cities in Serbia are affected by the impact of thermal power plants and the emission of harmful gases.

Еколошке и биогеографске последице процеса фрагментације

Еколошке и биогеографске последице процеса фрагментације

Author(s): Snežana Đurđić / Language(s): Serbian Issue: 1/2012

This paper will analyze the cause of, and ecological and biogeographical consequences of fragmentation process of habitats and ecosystems. Fragmentation process of the autochthonous habitats that without doubt leads also towards the break in their continuity shows by placement in all areas that are under the anthropogenic influence, and as well under the influence of the natural hazards. Spatial and functional isolation as the consequences of fragmentation can be overcome with the help of the formation of the ecological networks and corridors whose dynamic of management will be in accordance with the dynamic of change in habitats formed as the consequence of the fragmentation.

Оцена стања животне средине у Oпштини Сопот као услов одрживог развоја подручја општине

Author(s): Danijela Obradović-Arsić,Dejan Filipović / Language(s): English,Serbian Issue: 4/2011

The Sopot Municipality can be conditionally characterized as 'an ecological municipality' considering it is known for its preserved and quality environment, which is the result of the absence of greater sources of degradation and environmental pollution. The structure and usage of the Sopot municipality space was influenced by its specific position and historic development, the resources, the fact it is in the vicinity of Belgrade, as well as the processes taking places in the last few decades. Besides natural, anthropogenic factors substantially influenced the way of spatial development, often violating natural conditions and possibilities. In that sense, the current environmental condition analysis represents the important integral planning base for further spatial development of the Municipality. In this paper the environmental condition is shown according to single elements (air, water, soil), the attention is drawn to the problem of waste on the Sopot Municipality area, and in the end the valorization of the environment was performed from the aspect of pollution level.

Author(s): Dejan Filipović,Danijela Obradović / Language(s): English,Serbian Issue: 4/2009

In a few decades backwards in the city of Kraljevo occur certain problems with water quality, as well as with water supply. Based on the analysis of the present environmental state, the authors identified certain influences on the quality of the surface and ground water. Considering significant quantity of water recourses on this territory, as well as its threatened quality, it is necessary to pay attention much more on the problem of the pollution and protection of the surface and ground water.

Post Industrialist Pioneers. Gyűrűfű: An Ecological Anthropological Experiment

Author(s): Béla Borsos / Language(s): English Issue: 1/2017

Gyűrűfű, a small village in Zselic, South-Transdanubia depopulated in the 1970s, is the site of an eco-village experiment since 1990. In addition to some of the physical aspects of the project not covered earlier on, this paper deals with the human ecological features of the new community. Social-anthropological considerations such as community development, social background of the participants, the Communist past, which all are determining factors of the social model emerging on site, are discussed from the systems theoretical perspective which states that certain properties of a subsystem are always defined by the superimposed supersystem, both in physical geography and social organisation. The resulting tensions stretched social cohesion in the past 10–15 years, but new developments such as creating jobs by modern telecommunication means and achieving energy independence through the deployment of solar panels and passive energy conservation solutions off-set for these difficulties. The future of the experiment depends very much on three factors: generation change, immigration/emigration and conflict resolution.

‘Innovation from the Past.’ Silvopastoral Systems in Hungary in the Light of Hungarian Ethnographic Literature

Author(s): Anna Varga / Language(s): English Issue: 1/2017

Silvopastoral systems are a crucial part of the European cultural landscape and biocultural heritage. In Hungary, due to the intensification of agriculture and forestry management, silvopastoral practices were nearly totally abandoned during the last decades. In this paper, I review Hungarian ethnographic literature to discover the traditional silvopastoral management of Hungary. The papers were published in Hungarian, mainly in different ethnographic journals and in several books. In Hungary, until the passage of the Forest and Pastureland Separation Act (1853), forest grazing was a free right along with other silvopastoral methods, except pannage. Woodlands were natural shelters and sources of diverse fodder. Collecting leaf-fodder, leaf-litter, wild fruit and acorn were integral and common parts of traditional extensive livestock husbandry. The importance of silvopastoral systems increased during extreme weather conditions. All of them were controlled to avoid overuse and forest damage. Today, wood pasture management and illegal forest grazing is still alive, but the new forest law once again gives permission for regulated forest grazing in some cases. The openness towards silvopastoral managements is influenced by the new agroforestry innovations movement.

“If You Got a Forest, You Got Gold.” The Joys and Woes of Forest Use in Gyimes (Eastern Carpathians, Romania)

Author(s): Dániel Babai / Language(s): English Issue: 1/2017

All over the world, rural communities developed mainly stable and sustainable, traditional (extensive) land use systems to manage natural resources. Resource management and related traditional ecological knowledge based on understanding of the functioning of the ecosystem help local communities to maintain important resources, like forests. Forest plays an important socio-economic role in the life of rural communities. Wood is one of the most elemental raw materials used in households, but its non-timber benefits play just as important a role.We examined sustainable use of forests in a Csángó community in Gyimes region (Eastern Carpathians, Romania), providing insights into attitudes within folk forestry towards natural resources, driving forces, and changes in human relations with the forest. Wood as a raw material is a resource that largely determines the daily life of the Csángó community, while non-timber products (e.g., forest grazing, forest fruits, herbs) play a complementary, yet important role in Gyimes life. The survey of forest flora and vegetation confirms that Gyimes farmers are familiar with the plant species that reach significant coverage in the canopy, shrub and herbaceous layers, they are well versed in the forest types occurring in the landscape, their dynamics, their most characteristic stages in the succession after felling. Overuse is an undisputed and acknowledged part of the forest-management, threatens social-ecological system-flexibility. As long as natural systems are able to renew themselves (forests can regenerate), there is chance for the further use of this important resource and in a broader context there is chance for the survival of the local community as well.

Conflicts of Economic and Cultural Origin Between Farmers and Wild Animal Species in the Carpathian Basin — an Ethnozoological Approach

Author(s): Dániel Babai,Viktor Ulicsni,Ákos Avar / Language(s): English Issue: 1/2017

The multi-faceted relationship of society and wildlife is partly shaped by local perception determined by cultural or economic factors and resulting in positive or negative attitudes. The approach taken may influence the survival and the range of species and speciesgroups, in particular species associated with extremely negative emotions. Connections between local communities and wild vertebrate species were studied in four regions within the Carpathian Basin (Gömör/Gemer — Slovakia, Szilágyság/Sălaj — Romania, Gyimes/Ghimeş — Romania and Drávaszög/Baranja — Croatia). During the work, spontaneous manifestations obtained in semi-structured interviews aiming at the exploration of the locally known fauna were taken into account. Reviewing the five generally known families of vertebrates it can be stated, that — similarly to the global trends — the perception of amphibian and reptile species is extremely negative in the Carpathian Basin just as well. Most positive attitudes are related to bird species but due to presumed or true economic reasons some birds also include less favoured species. As to mammals, large predators are seen as harmful pests for husbandry and fearful for humans. The antipathy felt for bat species is an interesting phenomenon, mostly explained by their special physical constitution and mysterious lifestyle. The perception of local communities originating from cultural or economic factors and resulting in varying signs may have an impact on the size of the populations of certain species or species-groups. Ethnozoological research provides significant help to deeper knowledge about background of connections between local communities and species of wildlife, motivations behind the activities of society has become of paramount importance for development of conservation strategies.

Ethnomedicinal treatment of gastrointestinal disorders in Transylvania, Romania

Author(s): Nóra Papp,Mónika Tóth,Tünde Dénes,Kinga Gyergyák,Rita Filep,Sámuel Gergely Bartha,Rita Csepregi,Viktória Lilla Balázs,Ágnes Farkas / Language(s): English Issue: 1/2017

Ethnomedicine using mostly plants is of pivotal importance nowadays in several Transylvanian regions in Romania. In this study (2007–2015), one Swabian-German, one Hungarian, three Csángó-Hungarian and nine Székely-Hungarian villages were selected to collect ethnomedicinal treatments for various gastrointestinal diseases. Some of the studied villages have partial or no permanent medical and pharmaceutical services. The 374 inhabitants interviewed used mostly medicinal plants based on ancient knowledge. The 78 (53 wild and 25 cultivated) plants documented have 181 local names and are used to treat ailments such as loss of appetite, bloating, stomach ache, gastric ulcer, and diarrhea, mostly in tea form. This knowledge decreases continuously because of loss of interest among young people and through frequent use of media sources and books. Although some of these plants have also been described in official medicinal sources, several data suggest the need for further fieldwork and new experimental analyses to highlight the valuable role of these plants in recent phytotherapy.
