  4. The Legality of Foreign Military Activities in the Exclusive Economic Zone under UNCLOS

    Directory of Open Access Journals (Sweden)

    Jing Geng

    2012-02-01

    Full Text Available During negotiations for the United Nations Convention on the Law of the Sea (UNCLOS, military activities in another state's Exclusive Economic Zone (EEZ were a point of contention. Currently, the issue remains controversial in state practice. UNCLOS attempts to balance the differing interests of coastal and maritime states, but is silent or ambiguous on the legality of military operations in foreign EEZs. Coastal states seek to assert increasing control over their maritime zones while maritime states prioritize the freedom of navigation. This article examines the competing views on these issues in the context of the 2009 Impeccable incident between China and the United States that occurred in the South China Sea. The issue of military activities in the EEZ will continue to be a complex subject, without clear definitions in the nature and scope of permissible activity. As state practice evolves, the potential for hostilities is high, particularly in semi-enclosed sea areas such as the South China Sea. This article concludes that states should create dialogues and form agreements to help clarify the contours of military activity in the EEZ, focusing on mutual interests, interdependence, and coexistence rather than perceiving the ocean as a zero-sum resource. 

  5. Hypoxia in the central Arabian Gulf Exclusive Economic Zone (EEZ) of Qatar during summer season

    Science.gov (United States)

    Al-Ansari, Ebrahim M. A. S.; Rowe, G.; Abdel-Moati, M. A. R.; Yigiterhan, O.; Al-Maslamani, I.; Al-Yafei, M. A.; Al-Shaikh, I.; Upstill-Goddard, R.

    2015-06-01

    One of the most fascinating and unexpected discoveries during the Qatar University Marine Expeditions to the marine Exclusive Economic Zone (EEZ) of Qatar in 2000-2001, was the detection of a hypoxic water layer in the central region of the Arabian Gulf in waters deeper than 50 m. Hypoxia was defined as the region where the concentration of dissolved oxygen was less than 2 mg L-1. This article presents the discovery of hypoxia in the Arabian Gulf, based on samples collected (mainly during evening or night time) from vertical profiles along transects of the EEZ of Qatar and analyzed for physico-chemical properties, nutrients and chlorophyll-a. Hypoxia occurred in the summer months caused by an interaction between physical stratification of the water column that prevents oxygen replenishment, and biological respiration that consumes oxygen. Strong south-westerly winds (the SW monsoon) from June to September drive the relatively low-salinity nutrient-rich surface water from the Arabian Sea/Arabian Gulf (Sea of Oman) through the Strait of Hormuz into the central-Arabian Gulf, and this surface current penetration fertilizes the deep central-Arabian Gulf during the summer period. A strong seasonal pycnocline is formed between deeper waters at an ambient temperature of 20.9 °C and surface waters at 31.9 °C. This prevents the mixing of supersaturated O2 (>100-130%) water from the upper layer that would otherwise raise concentrations of dissolved oxygen below the thermocline, thus resulting in deep water hypoxia, i.e. dissolved oxygen levels of less than 0.86 ml L-1 at 17.3% saturation. These are the lowest values ever recorded for the Arabian Gulf. The calculated area of hypoxia is around 7220 square kilometers, and occurs in a layer about ≥15 m thick above the sea floor which extends toward the deep part of the Qatar Exclusive Economic Zone (EEZ). The biological consequences of this hypoxia on the sea floor are yet to be investigated.

Gastropod samples were collected from selected stations in the Sarawak EEZ using an otter trawl net with a stretched mesh size of 38 mm at the cod end. The trawling operations were conducted more than 12 nautical miles from the coast, and the area was divided into three depth strata: I) 20-50 m, II) 50-100 m and III) 100-200 m. A total of 23 gastropod species were identified during the two-month sampling period from 16 August until 6 October 2015, representing 8 superfamilies, 15 families and 20 genera. Superfamily Tonnoidea was represented by 7 species, followed by Muricoidea (5 species), Cypraeoidea (4 species), and Buccinoidea and Conoidea (both with 2 species). Other superfamilies were represented by a single species. Only 3 species were obtained in 2 depth strata, namely Melo melo , Murex aduncospinosus and Tonna galea . In addition, 9, 13 and 4 species of gastropods were found in strata I, II and III, respectively. The information on gastropod distributions at different depth strata in the Sarawak EEZ could be useful in updating the Malaysian species diversity database.

    Full Text Available Regulation is the cornerstone for utilizing marine fisheries resources, and thus Indonesian Government had implemented its Constitution as basic laws and rules. Those regulations need further elaboration. Therefore, Indonesian Government established sets of laws related to the utilization of marine fisheries resources, and in its implementation, those laws and regulations should never deviate from the Constitution of the Republic of Indonesia. The utilization of marine fisheries resources in Indonesia’s Exclusive Economic Zone enables the possibility of cooperation and colaboration with other countries. Therefore, Indonesia is required to seek by evaluating and complementing the laws in accordance with its Constitution. Pengaturan merupakan landasan utama pemanfaatan sumber daya perikanan, Indonesia telah menyiapkan aturan dasar yaitu Landasan Konstitusional. Pengaturan tersebut perlu penjabaran lebih lanjut. Oleh karena itu Indonesia membentuk aturan-aturan yang terkait dengan pemanfaatan sumber daya ikan dan dalam implementasinya aturan tersebut tidak boleh menyimpang dari aturan yang paling dasar. Pemanfaatan sumber daya ikan di Zona Ekonomi Eksklusif adalah pemanfaatan yang memungkinkan adanya pemanfaatan berbagi dengan negara lain maka Indonesia dituntut untuk segera dapat mencari dengan cara mengevaluasi dan melengkapi aturan sesuai dengan Landasan Konstitusional.

    Recent extensive activities of oil and gas exploration and production companies in the Israeli Exclusive Economic Zone (EEZ) raised the need for an up-to-date baseline mapping of the seafloor to assist policy makers. The baseline mapping focused on bathymetry, geomorphology, geology, biodiversity, infauna and habitat in order to compile a sensitivity map for the Petroleum Commissioner in the Ministry of Energy in the bid for opening the sea to new natural gas and oil explorations. The Israeli EEZ covers an area of 25,950 sq. km. and reaches a maximum water depth of 2,100 m. It is located within the Levantine Basin, a zone of compression and strike-slip tectonics as Africa pushes into Eurasia. These forces operate on a half kilometer thick of Messinian evaporates and over a dozen kilometers of Pliocene and Pleistocene sediments to produce a complex seafloor morphology. The margin is cut by numerous slumps and canyons, while the basin is traversed by deep sea channels emptying into the moat around Eratosthenes Seamount farther north. The bathymetric and geomorphological mapping was done in three phases using Kongsberg and Elac multibeam sonars installed on different research vessels. The last phase (Aug.-Sept., 2016) covering depths from 1,400 to 2,100 m used the Kongsberg EM302 sonar installed on our new governmental research vessel Bat Galim. It has "state of the art" capabilities to map, sample and analyze the water column, seafloor and sub-bottom from water depths of 10m to 7,000 m. These mapping capabilities are unique in our region, the Eastern Mediterranean and the Red Sea, so we hope to promote research collaborations with our neighbors.

    A sampling expedition into the East Coast Peninsula Malaysia Exclusive Economic Zone (EEZ) was carried in June 2008. Marine surface sediment samples were taken and the activity concentrations of 210 Pb have been determined. Its distribution was plotted and the findings show that the activity concentrations decline from north to south. On the other hand, the activity concentrations are increasing from west to east right to the edge of the EEZ. The highest activity concentrations were found to be near offshore oil platforms. The 210 Pb activity concentrations were found to be in the range of 18.3 - 123.1 Bq/ kg. (author)

    Full Text Available Decision I.C.J. from The Hague, since 3rd February 2009, in the case of “Romania vs. Ukraine - the maritime delimitation in the Black Sea”, has an important role in bilateral relations and regional plans of the riparian states and thus also eliminating a potential factor of instability at the sea border between the two countries and in the Black Sea. Drawing a line of demarcation equitable maritime economic zone and continental shelf between the two countries was an example of dispute settlement in the wider Black Sea area. Snake Island was not considered relevant in substantiating the court decision, because the I.C.J. has not declared it a rock, giving it a length of 12 nautical miles territorial sea and has not ruled on the nature of this formation, in accordance with the provisions of art. 121 of the Montego Bay Convention of 1982.

    The oil and natural gas exploitation in the Exclusive Economic Zone will propel the economy of the country, states and municipalities, due to tax revenues, jobs creation. It will also attract new businesses needed to support all the demand created by the main service and correlates. The Tax Service, under the municipal jurisdiction, is a major source of revenue. As the services are performed on the high seas and there is no law to regulate the territorial extent of each municipality, it can be argued that certain Artificial Island (oil platform, for example) is located within the extension of municipal sovereignty, which will allow the ISS taxation, problems will arise. This paper addresses these problems. (author)

    Large volumes of surface seawater samples were collected from thirty locations in the Exclusive Economic Zone (EEZ) of the east coast Peninsular Malaysia on June 2008 to study the activity concentrations of 137 Cs. The results will serve as additional information to the existing baseline data and is very useful for monitoring fresh input of anthropogenic radionuclide into Malaysian marine environment. In this study, the activity concentrations of 137 Cs were determined using co-precipitation technique, followed by Gamma Spectrometry measurement. The mean activity concentration of 137 Cs ranged between 3.40 and 5.89 Bq/m 3 . Higher activity concentrations were observed at the coastal and towards the south of Peninsular Malaysia and were aligned with the high turbidity. These may due to the rapid diffusion of 137 Cs from suspended particulates and fine sediments into surface seawater. The activity concentrations of 137 Cs observed in this study were slightly higher than the concentrations reported in seawater at the Straits of Malacca, Vietnam and Philippines. This might be because the study area received more input of 137 Cs that originated from global fallout and then deposited on land which later being transported subsequently into the coastal zone due to siltation and erosion processes. It could also be attributed to the intrusion of river waters containing higher concentrations of 137 Cs. (author)

    Today, 29 years after the Chernobyl accident, the Exclusion Zone still remains an areal unsealed radiation source of around 2600 km"2. It is not just a gigantic radioactive waste storage facility (the amount of radioactive waste accumulated within the Zone, except for the Shelter, is estimated at about 2.8 million m"3), but also a unique research and engineering platform for biologists, radiologists, chemists and physicists. Taking into account the amount of the radionuclides released during the accident, it becomes quite understood that the radiological environment in the Exclusion Zone is far from favorable. However, among the Exclusion Zone personnel who numbers 5000, there are female workers. The poster represents the results of the research performed among the female employees of the largest enterprise of the Exclusion Zone, “Chornobyl Spetskombinat”. The survey was performed with the view to knowing what makes women work in the most radioactively contaminated area in Europe, and what their role is, to revealing their fears and hopes, and to estimating the chances of the brave women of Chernobyl Exclusion Zone to succeed in their careers.

    Surface sediments were collected from sixteen locations in order to assess levels and sources of polycyclic aromatic hydrocarbons (PAHs) in sediments of Qatar exclusive economic zone (EEZ). Samples were analyzed for 16 parent PAHs, 18 alkyl homologs and for dibenzothiophenes. Total PAHs concentration (∑PAHs) ranged from 2.6 ng g(-1) to 1025 ng g(-1). The highest PAHs concentrations were in sediments in and adjacent to harbors. Alkylated PAHs predominated most of the sampling locations reaching up to 80% in offshore locations. Parent PAHs and parent high molecular weight PAHs dominated location adjacent to industrial activities and urban areas. The origin of PAHs sources to the sediments was elucidated using ternary plot, indices, and molecular ratios of specific compounds such as (Ant/Phe+Ant), (Flt/Flt+Pyr). PAHs inputs to most coastal sites consisted of mixture of petroleum and combustion derived sources. However, inputs to the offshore sediments were mainly of petroleum origin.

    We focus on the trace element geochemistry of particulate matter in the Exclusive Economic Zone (EEZ) of Qatar. A main goal of this research was to analyze a complete suite of trace elements on particulate matter samples from the water column from different oceanographic biogeochemical zones of the EEZ around Qatar. The sample set also includes plankton samples which are the main source of biogenic particles, dust samples which are a source of abiological particles to surface seawater and surface sediments which can be a source of resuspended particles and a sink for settling particles. The 15 metals and 2 non-metals analyzed in this study will be Al, Ti, V, Cd, Co, Cu, Fe, Mn, Ni, Pb, Zn, Mo, Ag, Ba, U and P, N. Many factors control the composition of trace elements in marine particles. Most of these are important in the EEZ of Qatar, including:1. Natural sources: These are rivers, atmospheric dust, sediment resuspension and leaks from oil beds. However, due to very limited rainfall rivers play no major role in Qatar but resuspension of shallow carbonate rich sediments and input of atmospheric dust are important due to strong currents and surrounding deserts.2. Adsorption/desorption: These chemical processes occur everywhere in the ocean and transfer metals between particles and the solution phase.3. Biological uptake: This process is likewise a universal ocean process and results in transport of metals from the solution phase to biological particles.4. Redox conditions: These are important chemical reactions in the oxic, suboxic and anoxic zones. This can be the dominant controlling mechanism in the northeastern hypoxic deeper waters of the Qatar EEZ.5. Anthropogenic sources: The eastern part of the Qatar contains numerous industrial sites, petroleum/gas platforms and refineries. There are numerous industrial sources but the main hot spots are the port of Doha and the industrial cities of Mesaieed, Khor Al-Odaid, and Ras Laffan. We aimed to determine the

    Full Text Available The jumbo flying squid Dosidicus gigas is widely distributed in the eastern Pacific Ocean and supports an important fishery. Although many studies have been carried out on the biology of this species, limited biological information is available in the waters outside the Exclusive Economic Zone of Chile (EEZ (20°S-41°S and 74°30’W-84°W. Three surveys were conducted in this area by the Chinese squid jigging vessels during the period from April 2006 to May 2008. The majority of the catch in the survey was from the two areas defined by 37°30’-41°S and 78°30’-80°W and by 25°-30°S and 76°-77°30’W. The sex ratio (M: F of the catch was 1: 2.48. The mean mantle length (ML was 376 mm for males with a range of 257-721 mm and 388.7 mm for females with a range of 236-837 mm. Two distinguished size classes, medium- and large-sized groups, were identified in this study with the medium-sized group (350-450 mm ML consisting of 89% of the total catch. The sizes at first sexual maturity were 638 mm ML for females and 565 mm ML for males. This study suggests that all the individuals examined were hatched from March 2007 to February 2008, indicating that D. gigas might spawn all year around with a peak spawning time from November 2007 to January 2008. Most of the stomachs analyzed had food remains. The preys included three major groups: fish (mainly lanternfish, cephalopods and crustaceans, but D. gigas was the dominant species in the stomach contents, showing strong evidence of cannibalism. The information obtained from this study improves our understanding of the fishery biology of D. gigas off Chile.

    Bartal, Y.; Villagran, M.; Ben Horin, Y.; Leonard, G.; Joswig, M.

    - In verifying compliance with the Comprehensive Nuclear-Test-Ban Treaty (CTBT), there is a motivation to be effective, efficient and economical and to prevent abuse of the right to conduct an On-site Inspection (OSI) in the territory of a challenged State Party. In particular, it is in the interest of a State Party to avoid irrelevant search in specific areas. In this study we propose several techniques to determine `exclusion zones', which are defined as areas where an event could not have possibly occurred. All techniques are based on simple ideas of arrival time differences between seismic stations and thus are less prone to modeling errors compared to standard event location methods. The techniques proposed are: angular sector exclusion based on a tripartite micro array, half-space exclusion based on a station pair, and closed area exclusion based on circumferential networks.

    Full Text Available Environmental changes and human activities can have strong impacts on biodiversity and ecosystem functioning. This study investigates how, from a quantitative point of view, simultaneously both environmental and anthropogenic factors affect species composition and abundance of exploited groundfish assemblages (i.e. target and non-target species at large spatio-temporal scales. We aim to investigate (1 the spatial and annual stability of groundfish assemblages, (2 relationships between these assemblages and structuring factors in order to better explain the dynamic of the assemblages' structure. The Mauritanian Exclusive Economic Zone (MEEZ is of particular interest as it embeds a productive ecosystem due to upwelling, producing abundant and diverse resources which constitute an attractive socio-economic development. We applied the multi-variate and multi-table STATICO method on a data set consisting of 854 hauls collected during 14-years (1997-2010 from scientific trawl surveys (species abundance, logbooks of industrial fishery (fishing effort, sea surface temperature and chlorophyll a concentration as environmental variables. Our results showed that abiotic factors drove four main persistent fish assemblages. Overall, chlorophyll a concentration and sea surface temperature mainly influenced the structure of assemblages of coastal soft bottoms and those of the offshore near rocky bottoms where upwellings held. While highest levels of fishing effort were located in the northern permanent upwelling zone, effects of this variable on species composition and abundances of assemblages were relatively low, even if not negligible in some years and areas. The temporal trajectories between environmental and fishing conditions and assemblages did not match for all the entire time series analyzed in the MEEZ, but interestingly for some specific years and areas.

    The coupling of fishing locations for R. kanagurta obtained from SEAFDEC and multi-sensor satellite imageries of oceanographic variables; sea surface temperature (SST), sea surface height (SSH) and chl-a concentration (chl-a) were utilized to evaluate the performance of maximum entropy (MaxEnt) models for R. kanagurta fishing ground for prediction. Besides, this study was conducted to identify the relative percentage contribution of each environmental variable considered in order to describe the effects of the oceanographic factors on the species distribution in the study area. The potential fishing grounds during intermonsoon periods; April and October 2008-2009 were simulated separately and covered the near-coast of Kelantan, Terengganu, Pahang and Johor. The oceanographic conditions differed between regions by the inherent seasonal variability. The seasonal and spatial extents of potential fishing grounds were largely explained by chl-a concentration (0.21-0.99 mg/m3 in April and 0.28-1.00 mg/m3 in October), SSH (77.37-85.90 cm in April and 107.60-108.97 cm in October) and SST (30.43-33.70 °C in April and 30.48-30.97 °C in October). The constructed models were applicable and therefore they were suitable for predicting the potential fishing zones of R. kanagurta in EEZ. The results from this study revealed MaxEnt's potential for predicting the spatial distribution of R. kanagurta and highlighted the use of multispectral satellite images for describing the seasonal potential fishing grounds.

    The development of renewable energy as a major component of efforts to combat climate change serves as the impetus for the location of energy production facilities in coastal ocean space. Yet, while many coastal nations see offshore renewable energy development as an important way forward, the speed and manner in which these efforts take shape vary dramatically. This paper assesses the role of coastal nations' domestic legal and policy frameworks in the siting of offshore renewable energy facilities in areas under federal jurisdiction. It focuses on two nations - Germany and the United States. Both have articulated their interest in renewable offshore energy, but while Germany has approved many offshore sites, recent US proposals have for the most part stalled. Based on a review of legal and policy documents, laws and regulations, academic literature, and interviews, this research identifies and compares factors that figure most prominently for the development of offshore renewable energy policies. Comparisons are organized under four categories: the regulatory framework, the public's role in siting, targeted economic mechanisms, and indirect mechanisms. The paper concludes with observations about prominent supports and impediments and suggestions for further research. (author)

    The United States Exclusive Economic Zone (EEZ) was established in 1983 and comprises all marine areas within 200 nautical miles (370 kilometers) of the nearest U.S. land. This vast area of 3.38 million square nautical miles (11.6 million square kilometers) is about 20 percent greater than the entire land area of the United States. The resource potential of the vast mineral deposits that occur within the U.S. EEZ is unknown, despite field studies that have taken place during the past 25 years. Since about 1975, information on marine mineral deposits has been obtained by numerous research cruises to the Pacific Ocean by the U.S. Geological Survey (USGS), the U.S. National Oceanic and Atmospheric Administration (NOAA), equivalent government agencies in Germany, Canada, France, Russia, Japan, China, South Korea, Australia, and New Zealand, and by academic researchers from all of these nations. Although most of the cruises by other nations explored areas outside the U.S. EEZ, information gained from those studies can aid in the evaluation of the mineral potential in the U.S. EEZ. However, the global effort remains inadequate to allow for the quantitative evaluation of mineral resources contained within the EEZ of nations or within international regions of the oceans.

    The present article shows how a lack of regulation has led to a certain degree of legal uncertainty as to whether offshore wind power plants located in the German Exclusive Economic Zone are amenable to German property law. For practical purposes this has made it necessary to negotiate project contracts such that the transfer of ownership of individual components is effected while these are still on shore, even if the purchase price has yet to be fully paid. The financing banks have a policy in place of demanding the establishment of a subsidiary which is to receive ownership of the assets. This makes the structure of such contracts a great deal more complicated in terms of corporations law and tax law. The present article summarises the experiences gained by lawyers in these matters, giving an overview of the different legal positions taken on them to date. It shows that the applicability of German property law follows from the law now in force. Aside from this the authors advocate amendments to the relevant IPR norm as a means of reinforcing legal certainty in practice and make a concrete proposal for a clause to this end.

    The studies of (137)Cs and (239+240)Pu distributions in surface seawater at South China Sea within the Exclusive Economic Zone (EEZ) of Peninsular Malaysia were carried out in June 2008. The analysis results will serve as additional information to the expanded baseline data for Malaysia's marine environment. Thirty locations from extended study area were identified in the EEZ from which large volumes of surface seawater samples were collected. Different co-precipitation techniques were employed to concentrate cesium and plutonium separately. A known amount of (134)Cs and (242)Pu tracers were used as yield determinant. The precipitate slurry was collected and oven dried at 60(o)C for 1-2 days. Cesium precipitate was fine-ground and counted using gamma-ray spectrometry system at 661.62keV, while plutonium was separated from other radionuclides using anion exchange, electrodeposited and counted using alpha spectrometry. The activity concentrations of (137)Cs and (239+240)Pu were in the range of 3.40-5.89Bq/m(3) and 2.3-7.9mBq/m(3), respectively. The (239+240)Pu/(137)Cs ratios indicate that there are no new inputs of these radionuclides into the area.

    Although many studies on the fishery biology of jumbo flying squid,Dosidicus gigas,have been conducted in the coastal areas within Exclusive Economic Zones (EEZs) of various countries due to its commercial and ecological importance,limited biological information is available from waters outside these EEZs.In this paper,we examined D.gigas fishery biology from waters outside Chilean,Peruvian and Costa Rican EEZs,based on the fishery data collected by Chinese jigging vessels during 2006 to 2010.The dominant mantle lengths of D.gigas were 350-450 mm,250-400 mm and 250-350 mm outside Chilean,Peruvian and Costa Rican EEZs,respectively.Size structure analysis show that a medium-sized group existed mostly in the waters outside the Chilean and Peruvian EEZs,whereas a small-sized group occurred mainly in the waters outside the Costa Rican EEZ.The longevity of the squid outside the Costa Rican EEZ was less than 10 months,while most of those outside Chilean and Peruvian EEZs were about 1-1.5 years and very few large individuals were 1.5-2 years old.A higher percentage of mature individuals existed outside Costa Rican EEZ implying the region as a potential spawning ground,while lower proportions of mature squid outside the Peruvian and Chilean EEZs indicated that spawning may be occurring outside our study area.Spatial differences in sizes at maturity of the squid are thought to be result from different environmental factors especially different temperature and nutrition among the three areas.Stomach-content analysis showed that cannibalism was important in the diet of D.gigas.Stress generated by jigging may increase the incidence of cannibalism.

    The analysis of radiation danger of the Exclusion Zone objects was made. Here, the Zone is defined as the territory from which the population has been evacuated in 1986 owing to the Chernobyl accident and possible outflow of the contaminated substances out of the borders is potentially dangerous to the Ukraine. In the present work were analyzed such problems as sources of radiation danger in the Zone, ways of radionuclide migration out of the borders of the Zone in normal and emergency situations, the non-radiation (ecological) danger factors of the Zone objects, doses (individual and collective) from various sources and on separate ways of their formation, and the characteristics of radiation danger of the Zone objects. The conclusions are: (1) Radionuclide flows both from technologic and natural sources exceed those from Shelter objects, (2) Under emergency conditions, radionuclide flows and doze loading remain comparable with those from emergency sources, (3) To solve some management tasks in radiation situation, the basic works on the Shelter objects should be oriented to decrease probability of emergency occurrence and to reduce radiation influence (prevention wash-outs during high waters, fire-prevention measures in forests and strengthening of the control behind non-authorized use of objects in the Zone).

    Nakane and Ohta (1986) revealed very high (6 %) prevalence rate of schizophrenia in A-bomb survivors. The goal of this study was the epidemiological investigation of schizophrenia in the Chernobyl exclusion zone personnel on the base of 10-years follow up study and analysis of the psychiatric archives (1986-1996). As a result the register of schizophrenia spectrum disorders has been created, including 65 staff members. According to both ICD-9 and ICD-10 criteria there were 48 patients with schizophrenia. It has been revealed a statistically significant increase of the schizophrenia percentage amongst all psychoses in the Chernobyl exclusion zone personnel in comparison with the general Ukrainian population. It has been established that among 48 cases of schizophrenia there were 39 (81.2 %) of schizophrenia onset occurred in the zone. Since 1990 a significant increase (more than 4 times: 5.4 per 10,000 in the zone and 1.1 per 10,000 in Ukraine) in schizophrenia incidence has been taking place among the irradiated population of the exclusion zone in comparison with the general population. Our data testify to possibility of radiation-induced schizophrenia onset, which seem to be like stochastic effects of ionizing radiation. The mechanisms of these effects realization are the subject of further investigations. (author)

    The peculiarity of Chernobyl exclusion zone is the existence of constant and a lot of temporary points of radioactive waste of Chernobyl origin disposal in it. Chernobyl zone (exclusion zone) is the territory round Chernobyl NPP restricted in the results of Chernobyl accident with no inhabitants in it and where the economic activity was almost stopped. Nowadays the apparatus is developed the test and assembling of the automatic control system are conducted. All the results of the radioactive waste mass measurement brought to the PRAWD by car automatically put into the PC. The devices of radiation control are moving above the RAW surface with the help of robot-manipulator. The delivery of RAW to the PRAMW is produced by special cars in circulating or single containers or loaded in bulk in the body of lorries with the closed roofs

    The Chernobyl reactor accident in April 1986 caused the release to atmosphere of substantial amounts of radioactivity. Precise estimates of the release vary. The USSR State Committee presented information to a meeting of the International Atomic Energy Agency in August 1986 indicating a release of some 2.9x10 5 TBq 137 Cs and 2x10 5 TBq 90 Sr, with a total fission/activation product release of 1.7x10 6 TBq. Other commentators suggest that up to double this amount may have been released. Estimates of deposition likewise vary, although it is probable that about half the released activity was deposited within 20 km of the release point, predominantly following two plume trajectories to the north and west. This resulted in the death of pine trees over 400 ha, the abandonment of 100,000 to 150,000 ha of agricultural land and the establishment of an exclusion zone extending to 30 km from the site. High levels of radionuclide contamination continue to prevail within the exclusion zone. Nonetheless, over the past fifteen years, re-colonisation has been widespread. Mixed deciduous woodlands, with a high proportion of birch (Betula spp.) and willow (Salix spp.), have become established in the forest areas, while agricultural land has succeeded to tall grassland and scrub. Field sites established in this study exhibited external gamma dose rates varying from 0.1 μSv h -1 to 140 μSv h -1 . Corresponding mean concentrations of 137 Cs in the top 20 cm of soil varied from about 6.10 2 to 3.10 6 Bq kg -1 dw. This study summarises observations over the period 2001 to 2004. Sub-surface activity, as measured by bait lamina penetration, appears to be inversely correlated with concentrations of 137 Cs and 90 Sr in soil. Likewise, at the very highest levels of contamination, there is some loss of invertebrate diversity; although little associated change in overall biomass. Between years, population densities and species dominance vary significantly. This does not appear to correlate

    The main task of the Geographical Information System of the Chernobyl exclusion zone is to estimate the applicability and perform the analysis of the body of radioecological information on the basis of which the administrative decisions about the use of territories can be made. This system is rather virtual and has several logical levels: storage of the primary radioecological and land use information; the analysis of possible ways for rehabilitation of contaminated lands; the economic evaluations based primarily on the cost-benefit comparison of scenarios with use of different countermeasures and those implementing usual technologies. This includes GIS-analysis and evaluation of risks as the basis for the decision-making. The paper presents the results of application of sophisticated GIS to the practice of radioecological research and land rehabilitation. (author)

    Neotectonic block differentiation of Chernobyl Exclusion zone area was fixed by the results of the geological and structure analysis of paleogene strata in complex with the space survey data interpretation. Structural plan of the latest tectonic movements had a block character; it was shown by the fracture systems, which represent the components of known regional tectonic zones of various trends and are found in the features of phanerozoic rock mass structure. The territory under study is divided into two parts - the northern one, where in the neotectonic movements are generally more intensive with manifestation practically all over the fracture zones, and the southern part, where in the newest breaks belong mainly to submeridional also to south-western regional fracture zones. The southern part of the Exclusion zone, as a whole, holds the greatest promise by comparison with the northern one in the view of neotectonic criteria regarding the geological repository siting for radioactive waste disposal

    . Within the framework of the IAEA Nuclear Security Program the technical cooperation project S trengthening Security of Nuclear Materials in Ukraine ( UKR/0/008) is aimed primarily to strengthen protection the entrance/exit checkpoints of the Chernobyl exclusion zone and adjacent State borders of Ukraine against illicit movement of radioactive materials (including nuclear materials). The particular situation of the exclusion zone presents a high risk of uncontrolled movement of radioactive materials from and into the exclusion zone. In view of the future construction of the S helter-2 a nd decommissioning of the three closed reactor blocks it is expected that the traffic through the exclusion zone will considerably increase in the next years and those large amounts of possibly contaminated metal scrap, construction material and equipment will leave the zone. There is also a risk of illegal movement of radioactive waste into the zone, possibly also through the international border, which could make the zone to an illegal dumping ground for radioactive waste. As practice shows theft of nuclear materials cannot be excluded. The general concept of the project is based on modernization of old and deployment of new vehicle (road and railway) and pedestrian monitoring equipment at all checkpoints of the exclusion zone including road checkpoints, train stations and river ports. A central station of data acquisition and management is to be located in Chernobyl. The equipment to be installed has to meet new technical requirements developed by IAEA. This includes, e.g. sensitivity of gamma and neutron detection, identification of innocent alarms caused by NORM materials or medical radioisotopes, accurate indication of the source position in the vehicle, and remote identification of license plate by advanced video systems. The implementation of the project and deployment of the equipment is expected to start in 2003 and should be completed in 2005. (Author)

The purpose of this article is research of the questions concerning the mode of the taxation of special economic zones. In Russia still there is no consensus about the sizes and the special economic zone types, the mechanism of their activity and approach to management. Development of uniform methodology is necessary for the Russian legislation for effective creation of activity of special economic zones taking into account features of a territorial arrangement. This methodology can be developed on the basis of positive experience of functioning of free economic zones of the different countries of the world. In the real work with the help of economic and statistical methods data on development and results of activity of a special economic zone in the territory of the Russian Federation and the China are collected and considered. As an example of successful functioning of the Russian special economic zone the special economic zone "Alabuga" is considered, as an example of functioning in the territory of the China special economic zone Shenzhen and joint industrial park of China and Singapore in the city of Suzhou are considered. The analysis of experience of the China has allowed to draw conclusions on efficiency of development of certain territories of the China through introduction of special economic zones. This fact substantially depends on efficiency of mechanisms of creation and development of economic educations, a possibility of self-government and financial independence in these territories, attraction of the foreign investment capital.

    Full Text Available A hydrophilic powder, QELBY, from the feldspar family of clay minerals was investigated for its ability to form structured or exclusion-zone (EZ water. We demonstrated microsphere-free zones around different fractions of the QELBY powder or its hydrated pellet. Averaging approximately 100 μm, these zones grew to a size similar to that formed in the vicinity of the Nafion standard. In the case of silica (control, only occasional microsphere-free zones of about 70 μm were found. Further, studies to investigate QELBY’s energizing effect on germination and early sapling growth in brown chickpea seeds showed at least a 2-3-fold increase in root length and/or formation of shoots. This was seen in seeds bathed in QELBY supernatants or surrounded by QELBY powder outside the vials containing the seeds. This indirect effect was observed whether the QELBY was dry or hydrated.

    The results of the researches of spices-specificity, accumulation dynamics and distribution of 90Sr, of 137Cs and of transuranic elements in fish of the Chernobyl NPP exclusion zone are analysed. The data of estimations of absorbed doze rate from incorporated radionuclides for pray fish and predatory species are given. For the fish from the lake of the left-bank floodplain of the Pripyat River the increase of 90Sr specific activity is registered which is presumably connected with the dynamics of the physical-chemical forms of the radionuclide in soils and their wash out in water bodies from the catchment basin. Now about 90% of internal dose rate of fish from closed aquatic ecosystems within the Chernobyl NPP exclusion zone is caused by 90Sr incorporation.

    As immobile organisms, plants have to tolerate unfavorable environmental conditions and make use of different adaptive mechanisms to survive and reproduce successfully under stress. It is often difficult to detect the organism s or population s response to stress factors due to slow changes of environmental conditions or delayed reactions of plants. From this point of view, the investigation of reactions under extreme environmental change offer unique opportunities to study adaptation mechanisms. Areas with a strong anthropogenic impact on the environment represent ideal places for research on adaptation or selection processes. For many decades, ionizing radiation is well known as a strong damaging and stress factor. Radiation exposure causes heavy damages of the DNA. This leads to a decrease in fitness in the present generation and inheritable mutations which reveal their effects in later generations. On the other hand, radiation exposure activates adaptation processes to ensure survival. The investigation of the influence of radiation at different levels of life organization from the DNA level to the population level can help to elucidate response mechanisms to changing environments. After the accident in 1986 at the Chernobyl Nuclear Power Plant, the surrounding territories were contaminated with high amounts of radioactive material. The exclusion zone became a natural laboratory for the investigation of effects of radiation on the biocenosis. Pinus sylvestris is one of the most wildly used species in radiation research due to its very high sensitivity to radiation exposure and dominance in forest ecosystems of the exclusion zone. Nuclear microsatellites (SSRs) and AFLP markers were investigated in order to study mutation rates and selection processes under the influence of radiation in the Scots pine (Pinus sylvestris) of different age and irradiation conditions collected in the Chernobyl exclusion zone and control areas. The results of this study show that a

    After the Chinese reform and opening up, the construction of economic zones, such as Special Economic Zones, Hi-tech Zones and Bonded Zones, has played an irreplaceable role in China’s economic development. Currently, against the background of Chinese economic transition, research on development evaluation of economic zones has become popular and necessary. Similar research usually focuses on one specific field, and the methods that are used to evaluate it are simple. This research aims to analyse the development evaluation of zones by synthesis. A new hybrid multiple criteria decision making (MCDM) model that combines the DEMATEL technique and the DANP method is proposed. After establishing the evaluation criterion system and acquiring data, the influential weights of dimensions and criteria can be calculated, which will be a guide for forming measures of development. Shandong Peninsula Blue Economic Zone is used in the empirical case analysis. The results show that Transportation Conditions, Industrial Structure and Business Climate are the main influencing criteria and measures based on these criteria are proposed. PMID:29301304

    A methodology for estimating the economic effects of different control zone sizes used in conflict resolutions between aircraft is presented in this paper. The methodology is based on estimating the difference in flight times of aircraft with and without the control zone, and converting the difference into a direct operating cost. Using this methodology the effects of increased lateral and vertical control zone sizes are evaluated.

    The dataset Spatial datasets of radionuclide contamination in the Ukrainian Chernobyl Exclusion Zone was developed to enable data collected between May 1986 (immediately after Chernobyl) and 2014 by the Ukrainian Institute of Agricultural Radiology (UIAR) after the Chernobyl accident to be made publicly available. The dataset includes results from comprehensive soil sampling across the Chernobyl Exclusion Zone (CEZ). Analyses include radiocaesium (134Cs and 134Cs) 90Sr, 154Eu and soil property data; plutonium isotope activity concentrations in soil (including distribution in the soil profile); analyses of hot (or fuel) particles from the CEZ (data from Poland and across Europe are also included); and results of monitoring in the Ivankov district, a region adjacent to the exclusion zone. The purpose of this paper is to describe the available data and methodology used to obtain them. The data will be valuable to those conducting studies within the CEZ in a number of ways, for instance (i) for helping to perform robust exposure estimates to wildlife, (ii) for predicting comparative activity concentrations of different key radionuclides, (iii) for providing a baseline against which future surveys in the CEZ can be compared, (iv) as a source of information on the behaviour of fuel particles (FPs), (v) for performing retrospective dose assessments and (vi) for assessing natural background dose rates in the CEZ. The CEZ has been proposed as a radioecological observatory (i.e. a radioactively contaminated site that will provide a focus for long-term, radioecological collaborative international research). Key to the future success of this concept is open access to data for the CEZ. The data presented here are a first step in this process. The data and supporting documentation are freely available from the Environmental Information Data Centre (EIDC) under the terms and conditions of the Open Government Licence: https://doi.org/10.5285/782ec845-2135-4698-8881-b38823e533bf.

    Species-specificity and dynamics of 90Sr, 137Cs and some transuranic elements accumulation in bivalve and gastropod freshwater molluscs of the Chernobyl exclusion zone during 1997-2008 was analyzed. The results of radiation dose and chromosome aberration rate estimation and the analysis of hemolymph composition of freshwater snail (Lymnaea stagnalis L.) was produced. The absorbed dose rate was registered in the range of 0.3-85.0 microGy/h. In closed water bodies the heightened chromosome aberration rate (up to 27%) in embryo tissues, and also the change of haematological indexes for the adult individuals of snails was registered.

    In Chernobyl exclusion zone area the 137 Cs accumulation by mushrooms (macromycetes) of different types is investigated. The main factor influencing radiocaesium content value in mushrooms-symbiotrophes, is the depth of location in ground of the main part of mycelium of each kind. For macromycetes, whole mycelium is located in the soil in 0 - 5 or 5 - 10 cm layers, 137 Cs accumulation occurs in two stages. The first stage is characterised by gradual increase (from year to year) of 137 Cs concentration in fruit bodies of mushrooms; the second stage - abrupt decrease of radionuclide contents. The maximum 137 Cs amount in macromycetes of different kinds are marked in 1996-1998 years. In the year of 2000 on 2 zone test sites the change of the ratio of 137 Cs contents in mushrooms-symbiotrophes with different depth of mycelium's localization for first time was marked

    A comparative cytogenetic examination of 33 self-settlers in the 30 km ChNPP Exclusion Zone and 31 residents in villages of Yahotyn district, Kyiv region was carried out in 1998-99. The levels of soil contamination of their residential areas with "1"3"7Cs, "9"0Sr and "2"3"8","2"3"9"+"2"4"0Pu were 74–477 kBq/m"2, 33–288 kBq/m"2 and 1.5-10.0 kBq/m"2, respectively for the former, and 1.9–5.8 kBq/m"2, 0.6–2.8 kBq/m"2 and 0.01-0.05 kBq/m"2, respectively for the latter. Using various data about the radiation situation in the Exclusion Zone, the effective doses on whole-body of the self-settlers were estimated to be 30–333 mSv for the whole residing period after the accident. The mean frequencies of aberrant cells and chromosomal aberrations for the Zone self-settlers were significantly higher than those for the residents in Yahotyn district, while the values of the latter group were found to be above the spontaneous levels reported in literatures. The individual variability in the distribution of the same indices was significantly larger for the self-settlers than for the Yahotyn residents. The compared groups also differ in the distribution of aberrations in cells. A repeated examination of 20 Zone self-settlers was conducted in 2001. A significant decrease in chromosome type aberration frequency was found at the expense of fragments frequency decrease. However, the total frequency of chromosomal aberrations didn't differ in 1998-99 and in 2001. (author)

    Context In 1997, Congress authorized the Food and Drug Administration (FDA) to grant 6 month extensions of marketing rights through the Pediatric Exclusivity program if industry sponsors complete FDA-requested pediatric trials. The program has been praised for creating incentives for studies in children; it has been criticized as a “windfall” to the innovator drug industry. This critique has been a substantial part of Congressional debate on the program, which is due to sunset in 2007. Objective To quantify the economic return to industry for completing Pediatric Exclusivity. Design Cohort study of programs conducted for Pediatric Exclusivity. We selected 9 drugs that were granted Pediatric Exclusivity. From the final study reports submitted to FDA, we obtained key elements of the clinical trial design and study operations. We estimated the cost of performing each study and converted these into estimates of after-tax cash outflows. We obtained 3-year market sales and converted these into estimates of after-tax cash inflows based upon 6 months of additional market protection. We then calculated the net economic return (cash inflows less outflows) and ratio net return to costs (net economic return divided by cash outflows) for each product. Main Outcome Measures Net economic return and ratio of net return to cost. Results The indications studied reflected a broad representation of the program: asthma, tumors, attention deficit disorder, hypertension, depression/generalized anxiety disorder, diabetes, gastroesophageal reflux, bacterial infection, and bone mineralization. The distribution of net economic return for 6 months of exclusivity varied substantially among products [net return ranged from (−)$8.9 million to (+)$507.9 million; ratio of return to cost ranged from −0.68 to 73.6] Conclusions The economic return for pediatric exclusivity is highly variable. Pediatric Exclusivity, as an incentive to complete much-needed clinical trials in children, can

Theoretical principles and methodology of estimation of the phenomenon of social exception are analyzed. Certain characteristic lines of social exception: subzero even consumptions and profit of individuals or groups; a limit access is to the public mechanisms of increase of welfare; a mainly passive type of cooperating is with society. Attention is accented on a defect for the individuals of row of rights, limit nature of access to the institutes that distribute resources, to the labor-market. Poverty is certain the main category of social exception. A concept "circles of poverty" and mechanisms of its existence are reasonable. Other displays of social exception-direct violation of base human rights are examined on quality education, on medical services and kind health, on the acceptable standard of living, on access to cultural acquisition, on defense of the interests and on the whole on participating in economic, social, in a civilized manner, political life of country.

    This article describes major studies performed by the Chernobyl Center's International Radioecology Laboratory (Slavutich, Ukraine) on radioecology of murine rodents and shrews inhabiting the Chernobyl Exclusion Zone. The article addresses the long-term (1986-2005) and seasonal dynamics of radioactive contamination of animals and reviews interspecies differences in radionuclide accumulations and factors affecting the radionuclide accumulations. It is shown that bioavailability of radionuclides in the "soil-to-plant" chain and a trophic specialization of animals play key roles in determining their actual contamination levels. The total absorbed dose rates in small mammals significantly reduced during the years following the Chernobyl Nuclear Power Plant accident. In 1986, the absorbed dose rate reached 1.3-6.0 Gy h(-1) in the central areas of the Chernobyl Exclusion Zone (the "Red Forest"). In 1988 and 1990, the total absorbed dose rates were 1.3 and 0.42 Gy h(-1), respectively. In 1995, 2000, and 2005, according to the present study, the total absorbed dose rates rarely exceeded 0.00023, 0.00018, and 0.00015 Gy h(-1), respectively. Contributions of individual radiation sources into the total absorbed dose are described.

    Full text: Our studies were carried out during 1997-2007 within Krasnensky flood-lands on the left bank of the Pripyat River, which is the most contaminated region of the Ukrainian part of the Chernobyl accident exclusion zone. During 1991-1993 the complex of hydraulic engineering structures as flood protection dams was constructed within the Krasnensky flood-lands, which preventing washing away of radioactive substances from soils and changing a hydrological mode of flood plain flows during a high water. In its turn it was by the reason of strengthening of over-moistening and swamping processes within embankment territories. As a result - on a background of the common tendencies of increase of the mobile forms of 90 Sr in soils of catchment territories and bottom sediments of the exclusion zone, there is an increase of humic acids concentrations in waterlogged soils of Krasnensky flood-lands. It is also raises the content of the water-soluble forms of 90 Sr forming with acids the soluble complexes. Thus the increase of concentrations of the mobile radionuclide forms and their inclusion into biotic circulation of aquatic ecosystems is observed. It confirms also an increase of 90 Sr specific activity in water of lakes within Krasnensky flood-lands, against a background of stabilisation of this parameter for 137 Cs last years. Such dynamics of 90 Sr and 137 Cs contents is significantly reflected on dose rate for hydrobionts due to incorporated radionuclides. However if in running water bodies the decrease of radionuclide contents defines, accordingly, and the decrease of dose rates, in lakes of the left-bank flood-lands of the Pripyat River the situation has an absolutely other character. At rather stable internal absorbed dose rate, caused by 137 Cs during 1993-2007, the dose, caused by the 90 Sr content, has grown more than in 20 times for some species of higher aquatic plants and fish in comparison with the beginning of 1990-s. As a result the total internal dose

    For past 17 years after accident the character of radioactive contamination of water objects within the Chernobyl NPP exclusion zone has undergone essential changes. First of all it connected with realisation on a wide area of deactivation works, and also with transformation of radioactive substances in water-soil systems. Besides, during 1991-95 the complex of hydraulic engineering structures as protection dams, interfering washing away of radioactive substances from soils of the left-bank catchment basin and changed a hydrological regime of these territories during a high water, was constructed. The levels of radionuclide contamination of water objects within the Chernobyl NPP exclusion zone was rather stabilised. Due to high water change rate the river bottom sediments have undergone decontamination processes (especially during floods and periods of high water) and over the years have ceased to play the essential role as a secondary source of water contamination. On the other hand, the closed reservoirs have considerably higher levels of radioactive contamination caused by limited water change and by relatively high concentration of radionuclides deposited in the bottom sediments. Therefore, for the majority of standing reservoirs the level of radionuclide content is determined mainly by the rates of mobile radionuclide forms exchange between bottom sediment and water, as well as by the external washout from the catchment basin. In this paper will be considered: (1) the latest data on radionuclide content (Sr-90, Cs-137, Pu-238, Pu-239+240 and Am-241) and dynamics in water, seston, bottom sediments and hydrobionts of different trophic levels and ecological groups; (2) the peculiarities of formation of vegetative communities from lakes within embankment territory of Pripyat River flood-lands and its impact on radionuclide redistribution in aquatic ecosystems; (3) the major hydrochemical factors, which determine the behaviour of radionuclides in the aquatic

    Full text: The only Hungarian nuclear power plant (Paks NPP) generates about 40 percent of the electrical energy of Hungary. Taking into consideration the designed lifetime, the four units should be shut down between 2012 and 2017. To extend operation of the units with twenty years can be considered as the especially important part of the life-time management. In terms of life-time extension, beside technical issues and nuclear safety, the public acceptance plays a very decisive role. The Chernobyl accident had serious impact on the public; therefore, enhancing the public confidence is a main task in respect of the future of nuclear energy. The Hungarian Nuclear Society (HNS) and the Hungarian Young Generation Network (YGN), which operates within the framework of HNS, has been put already a lot of effort into it. Between 28th of May and 4th of June, 2005, under the organization of the Hungarian Nuclear Society, a scientific expedition visited the Chernobyl Nuclear Power Plant site and the surrounding exclusion zone. Most of the participants were young Hungarian nuclear experts under the leading of more experienced colleagues. The main goals of the expedition were the followings: Getting own experiences in a direct way about the actual condition of the Chernobyl Power Plant and the contamination and the dose level of its surroundings; Gathering information about the condition of the shelter built above the damaged 4th unit; Further education of young nuclear experts by performing field measurements; Communicating to the public on our experience and consequences of the accident by utilizing our authentic measurements. The Hungarian expedition successfully achieved its objectives performing wide-ranged environmental and dosimetric measurements and collecting numerous biological and soil samples. The analysis of samples has been started immediately in the International Chernobyl Center in Slavutich. The dosimetric measurements showed that no considerable exposure of

    The Chernobyl reactor accident in April 1986 caused the release to atmosphere of some 2 x 10 6 TBq, or more, of total fission/activation products. Estimates of deposition vary, although it is probable that about half the activity was deposited within 20 km of the release point, predominantly following two plume trajectories to the north and west. This resulted in the death of pine trees over 400 ha, the abandonment of up to 150 000 ha of agricultural land and the establishment of an exclusion zone extending to 30 km from the site. High levels of radionuclide contamination continue to prevail within the exclusion zone. Nonetheless, recolonisation has been widespread. Mixed deciduous woodlands, with a high proportion of birch (Betula spp.) and willow (Salix spp.), have become established in the forest areas, while agricultural land has succeeded to tall grassland and scrub. Field sites investigated in this study, during 2001-2003, exhibited external gamma dose rates varying from 0.1 μSv h-1 to 140 μSv h-1. Corresponding mean concentrations of 137 Cs in the top 20 cm of soil varied from about 6 x 10 2 to 3 x 10 6 Bq kg -1 dw (dry weight). Little impact is evident on populations of small mammals in these areas, either for species diversity or overall abundance, although there is a slight (not statistically significant) trend for increasing spleen weight in the bank vole with increasing levels of contamination. Previous suggestions that populations contain a preponderance of juveniles and sub-adults at the highest contaminated sites are not supported. (author)

    Changes of genetic structures due to viability selection are likely to occur in populations exposed to rapidly and extremely changing environmental conditions after catastrophic events. However, very little is known about the extent of selective responses and in particular the proportion of the genome involved in putatively adaptive reactions for non-model plants. We used amplified fragment length polymorphisms (AFLPs) in order to investigate genetic differences between pine (Pinus sylvestris) trees which were partially exposed to extreme environmental conditions. Genetic variation patterns of pines exposed to high radiation in the Chernobyl exclusion zone with or without phenotypic stress symptoms were compared to control trees with a similar origin. Six percent of the investigated loci (15 of 222 loci) were identified as candidates for selective responses. Moderate differentiation was observed between groups of trees showing either weak or strong phenotypic responses to high radiation levels. - Highlights: → Genetic variation patterns of pines exposed to high radiation were investigated. → Pines with or without phenotypic stress symptoms were compared to control trees. → AFLP markers were used to reveal evidences of selection processes. → 15 of 222 loci are identified as candidates for selective responses. → Moderate differentiation is observed between irradiated and control trees. - Genetic responses to the exposure of trees to radiation in the Chernobyl zone may involve adaptive changes at a comparatively large part of the genome.

    The Chernobyl nuclear disaster resulted in contamination of vast areas in Europe. To date, there is little knowledge about the effects of radioactive contamination on tick species. We sampled ticks from vegetation and large-sized wild mammals belonging to orders Carnivora and Artiodactyla at sites with 0.76, 1.91, and 4.50 mSv/hr ionizing radiation background values in the Polesky State Radio-Ecological Reserve of the Chernobyl nuclear disaster zone in spring 2010. Altogether, 122 questing ticks were collected from vegetation. Among collected ticks, Dermacentor reticulatus (Fabricius) was, by far, the most abundant species (99.2%), followed by Ixodes ricnus (L.) (0.8%), which was collected only at the 0.76 mSv/hr site. The average sex ratio female∶male was 2.9∶1.0. In parallel with the present study, we examined 3 Sus scrofa (L.), 2 Nyctereutes procyonoides (Gray), and 1 Alces alces (L.) at the 4.50 mSv/hr site; 96 D. reticulatus ticks were found on 2 N. procyonoides specimens. The mean density and the intensity of infestation were 16 ticks per animal and 48 ticks per infested animal, respectively. Future investigations are warranted to further characterize the role of various tick vectors, vertebrate reservoirs, and diversity of tick-borne pathogens in the Chernobyl exclusion zone.

    generate a light pulse. The cluster is composed of three scintillator tubes bound tightly together in a lead sheath. The lead plug and sheath provide gamma radiation shielding, but unfortunately, the sheath design does not fully shield the tube axial length circumferentially. The top of the sheath is basically open and can allow SNF scatter gamma rays that penetrate the concrete wall to encounter and strike the scintillator material without attenuation. Despite the fact that the detector cluster is at the 13 ft 1 in. elevation above the IFSF floor 0 ft 0 in. elevation, the potential for this detector cluster to inadvertently alarm is real. The CAS detector has been designed with a 10,000:1 gamma rejection ratio and zero response above background in gamma radiation fields le10 rads/h. The authors solution to prevent inadvertent criticality alarms involves setting up an exclusion zone around the detectors. Individual elements or loaded canisters would be prohibited from entering the exclusion zone. Centered about the CAS and extending from the north wall into the hot cell and from the hot-cell ceiling to an elevation below the detector elevation, the exclusion zone boundaries and dimensions were determined analytically

    The effects of radioactive contamination on ecosystem processes such as litter decomposition remain largely unknown. Because radionuclides accumulated in soil and plant biomass can be harmful for organisms, the functioning of ecosystems may be altered by radioactive contamination. Here, we tested the hypothesis that decomposition is impaired by increasing levels of radioactivity in the environment by exposing uncontaminated leaf litter from silver birch and black alder at (i) eleven distant forest sites differing in ambient radiation levels (0.22–15 μGy h{sup −1}) and (ii) along a short distance gradient of radioactive contamination (1.2–29 μGy h{sup −1}) within a single forest in the Chernobyl exclusion zone. In addition to measuring ambient external dose rates, we estimated the average total dose rates (ATDRs) absorbed by decomposers for an accurate estimate of dose-induced ecological consequences of radioactive pollution. Taking into account potential confounding factors (soil pH, moisture, texture, and organic carbon content), the results from the eleven distant forest sites, and from the single forest, showed increased litter mass loss with increasing ATDRs from 0.3 to 150 μGy h{sup −1}. This unexpected result may be due to (i) overcompensation of decomposer organisms exposed to radionuclides leading to a higher decomposer abundance (hormetic effect), and/or (ii) from preferred feeding by decomposers on the uncontaminated leaf litter used for our experiment compared to locally produced, contaminated leaf litter. Our data indicate that radio-contamination of forest ecosystems over more than two decades does not necessarily have detrimental effects on organic matter decay. However, further studies are needed to unravel the underlying mechanisms of the results reported here, in order to draw firmer conclusions on how radio-contamination affects decomposition and associated ecosystem processes. - Highlights: • The effects of radioactivity on

    In radioecology, the need to understand the long-term ecological effects of radioactive contamination has been emphasised. This requires that the health of field populations is evaluated and linked to an accurate estimate of received radiological dose. The aim of the present study was to assess the effects of current radioactive contamination on nematode assemblages at sites affected by the fallout from the Chernobyl accident. First, we estimated the total dose rates (TDRs) absorbed by nematodes, from measured current soil activity concentrations, Dose Conversion Coefficients (DCCs, calculated using EDEN software) and soil-to-biota concentration ratios (from the ERICA tool database). The impact of current TDRs on nematode assemblages was then evaluated. Nematodes were collected in spring 2011 from 18 forest sites in the Chernobyl Exclusion Zone (CEZ) with external gamma dose rates, measured using radiophotoluminescent dosimeters, varying from 0.2 to 22 μGy h −1 . These values were one order of magnitude below the TDRs. A majority of bacterial-, plant-, and fungal-feeding nematodes and very few of the disturbance sensitive families were identified. No statistically significant association was observed between TDR values and nematode total abundance or the Shannon diversity index (H′). The Nematode Channel Ratio (which defines the relative abundance of bacterial- versus fungal-feeding nematodes) decreased significantly with increasing TDR, suggesting that radioactive contamination may influence nematode assemblages either directly or indirectly by modifying their food resources. A greater Maturity Index (MI), usually characterising better soil quality, was associated with higher pH and TDR values. These results suggest that in the CEZ, nematode assemblages from the forest sites were slightly impacted by chronic exposure at a predicted TDR of 200 μGy h −1 . This may be imputable to a dominant proportion of pollutant resistant nematodes in all sites. This might

    Shortly after the explosion of the Chernobyl nuclear power plant (ChNPP) in 1986, radioactive fall-out and contaminated trees (socalled Red Forest) were buried in the Chernobyl Exclusion Zone (ChEZ). These days, exact locations of the buried contaminated material are needed. Moreover, 3D vegetation maps are necessary to simulate the impact of tornados and forest fire. After 30 years, some of the so-called trenches and clamps are visible. However, some of them are overgrown and have slightly settled in the centimeter and decimeter range. This paper presents a pipeline that comprises 3D vegetation mapping and machine learning methods to precisely map trenches and clamps from remote sensing data. The dataset for our experiments consists of UAV-based LiDAR data, multi-spectral data, and aerial gamma-spectrometry data. Depending on the study areas overall accuracies ranging from 95.6 % to 99.0 % were reached for the classification of radioactive deposits. Our first results demonstrate an accurate and reliable UAV-based detection of unknown radioactive biomass deposits in the ChEZ.

    Tick occurrence was studied in the Chernobyl exclusion zone (CEZ) during the August-October 2009-2012. Dermacentor reticulatus ticks were collected using the flagging method and then screened for infection with Anaplasma phagocytophilum and Babesia canis by a PCR method incorporating specific primers and sequence analysis. The prevalence of infection with B. canis canis and A. phagocytophilum was found to be 3.41% and 25.36%, respectively. The results present the first evidence of B. canis canis and A. phagocytophilum in questing D. reticulatus ticks from the Chernobyl exclusion zone. They also reveal the presence of tick-borne disease foci in areas with no human activity, and confirm that they can be maintained in areas after a nuclear disaster with radioactive contamination.

    During 1998-2014 the rate of chromosomal aberrations in embryo tissues of the pond snail (Lymnaea stagnalis) and root meristems of higher aquatic plants, and also hematologic indexes of mantle liquid of the adult snails and peripheral blood of fishes in water bodies within the Chernobyl exclusion zone (EZ) was studied. The absorbed dose rate for hydrobionts from water bodies of the EZ registered in a range from 0.25 to 420 μGy h(-1) and in the reference ones - up to 0.09 μGy h(-1). The level of chromosomal aberrations in the molluscs from the most contaminated water bodies of the EZ was registered within range of 18-27% and for the molluscs from the reference lakes this index was on the average 1.5% with the maximal values 2.3%. The rate of chromosomal aberrations in root meristematic cells of higher aquatic plants from the contaminated lakes of the EZ was in range of 7-17% and in the plants from reference water bodies was not exceed 2.1%. The positive correlation between chromosomal aberration rate and absorbed dose rate in the pond snail's embryos and root meristems of higher aquatic plants in water bodies of the EZ was registered. Analysis of hemolymph structure of snails from the most contaminated water bodies showed a high rate of dead and phagocytic cells as well as decrease of the young amoebocytes quantity. Hematologic research of fish allows to determine on the one hand an insignificant changes of leukogram structure, and from the other hand a high level of red cells with different abnormalities in the peripheral blood of fishes from the water bodies with high levels of radioactive contamination. It is suppose that qualitative indexes of red cells in peripheral blood of fish are more sensitive to long-term radiation impact in comparison with elements of white blood, which can be used for conducting of the hematologic monitoring of radioactive contaminated water bodies.

Our researches were carried out during 1999-2007. The water bodies of research were Azbuchin Lake, Yanovsky Crawl, Dalekoye Lake, Glubokoye Lake as well as Uzh River and Pripyat River within the Chernobyl accident exclusion zone. The results of the analyses compared to the data received for hydrobionts from control lakes, located within the Kiev City area. The absorbed dose rate registered in range from 1.3 mGy/year to 3.4 Gy/year. The highest rate was found in Dalekoye and Glubokoye lakes, the lowest - in the Pripyat River and Uzh River. Hydrobionts from the control lakes were characterized by absorbed dose rate about 0.3 mGy/year The rate of chromosome aberration for snails from the control lakes was about 1.1-2.0 percent. About 3.3 and 5.7 % of aberrant cells was registered in snail's embryo from the Pripyat and Uzh rivers respectively. The highest rate of aberration was found in snails from lakes within the dammed territory on the left-bank flood lands of the Pripyat River (Dalekoye-1 Lake and Glubokoye Lake) - 21-23 %. In the embryo tissue of snails from Yanovsky Crawl chromosome aberration rate was about 18 % and in Azbuchin Lake - about 20 %. The highest chromosome aberrations rate in root meristems (17.8-10.8 %) were registered in plants from lakes within the left-bank flood lands of the Pripyat River, the lowest one (4.5-2.2 %) - in plants from the Pripyat and Uzh rivers. In hemo lymph of snails from Dalekoye-1 Lake, Azbuchin Lake and Glubokoye Lake the quantity of death cells averages 36.2 %, 39.2 % and 43.8 % respectively, the part of phagocytic cells averages 44.3 %, 41.2 % and 45.0 %, as well as decrease of the young

Its concentration has increased many times after the Chernobyl disaster and can be expected to increase about 40 times in the future. This research concentrated on the contaminated exclusive Chernobyl zone polluted by trace radionuclides, their behavior and accumulation by various plant species.

The plant samples of Oenothera biennis, Betula pendula and Quercus robur were collected from the Yanov district, where the soil contamination by 241 Am and 137 Cs was at the level of 660 and 27 MBq/m 2 , respectively. Gamma spectroscopy and radiochemical methods were used to estimate the activity concentration of 137 Cs, 90 Sr, 238 Pu, 239+240 Pu, 241 Am. The radionuclides were measured in the dry green mass of the plant samples and in the dry soils. The contamination of the Oenothera biennis, Betula pendula and Quercus robur samples by 137 Cs was (5.8±1,5)x10 6 , (7.4±1.1)x10 5 , and (2.6±0.2)x10 6 Bq/kg dry mass, respectively, and contamination by 241 Am was 47±5, 45±3 and 3.2±0.2 Bq/kg, respectively. The soil-to-plant transfer ratio for 137 Cs ranged lay within the interval of 0.2 to 0.03 Bq/kg : Bq/m 2 , the the transfer ratio for 241 Am did not exceed 7x10 -5 Bq/kg : Bq/m 2 . The coefficient of the relative contents of the 241 Am/ 239+240 Pu radionuclides in the various plant samples varied from 3.2 to 8.3, while for soil from

    Nuclear pore complexes (NPCs) mediate nucleocytoplasmic movement. The central channel contains proteins with phenylalanine-glycine (FG) repeats, or variations (GLFG, glycine-leucine-phenylalanine-glycine). These are 'intrinsically disordered' and often represent weak interaction sites that become ordered upon interaction. We investigated this possibility during nuclear transport. Using electron microscopy of S. cerevisiae, we show that NPC cytoplasmic filaments form a dome-shaped structure enclosing GLFG domains. GLFG domains extend out of this structure and are part of an 'exclusion zone' that might act as a partial barrier to entry of transport-inert proteins. The anchor domain of a GLFG nucleoporin locates exclusively to the central channel. By contrast, the localisation of the GLFG domains varied between NPCs and could be cytoplasmic, central or nucleoplasmic and could stretch up to 80 nm. These results suggest a dynamic exchange between ordered and disordered states. In contrast to diffusion through the NPC, transport cargoes passed through the exclusion zone and accumulated near the central plane. We also show that movement of cargo through the NPC is accompanied by relocation of GLFG domains, suggesting that binding, restructuring and movement of these domains could be part of the translocation mechanism.

    During 1998-2013 we studied the rate of chromosomal aberrations in embryo tissues of the pond snails and root meristems of higher aquatic plants, and also hematologic indexes of mantle liquid of the snails and peripheral blood of fishes in water bodies with different levels of radioactive contamination within the Chernobyl exclusion zone (ChEZ). The absorbed dose rate for hydrobionts from water bodies of the ChEZ during the period of researches registered in a range of 4.6.10{sup -3} - 3.4 Gy year{sup -1}, and in the control water bodies - up to 1.7.10{sup -3} Gy year{sup -1}. Cytogenetic analysis of embryos of the pond snail Lymnaea stagnalis testifies the increased level of chromosomal aberrations in the mollusks from stagnant water bodies of the ChEZ in comparison with control reservoirs. During the period of studies the highest values were registered for the snails of closed reservoirs of the ChEZ (Glubokoye Lake, Dalyokoe Lake, Azbuchin Lake etc.) where the rate of chromosomal aberrations was registered within range of 18-27%, that on the average more than in 10 times exceeds the spontaneous mutagenesis level for aquatic species. The pond snails of river ecosystems were characterized by the low level of aberrant cells - 2.5-3.5%. For the mollusks from the control lakes this index was reached on the average 1.5% with the maximal values 2.3%. The positive correlation between chromosomal aberration rate and absorbed dose rate in the pond snails' embryos in water bodies of the ChEZ was registered. The rate of chromosomal aberrations in root meristematic cells of higher aquatic plants (Phragmites australis, Stratiotes aloides, Glyceria maxima, Butomus umbellatus, Sparganium erectum and Sagittaria sagittifolia) from the most contaminated lakes of the ChEZ was in range of 7-17%. In the plants of rivers this index was on the average 3.5-5.0%, and was not exceed 2.6% in control water bodies. Thus, the rate of chromosomal aberrations in hydrobionts of the stagnant

    The aim of the study was to assess the effects of former radioactive contamination on the structure of the nematode community in sites affected by the fallout from the Chernobyl accident that occurred on 26, April 1986. Nematodes were collected in spring 2011 from 18 forest sites of the Chernobyl Exclusion Zone (CEZ). The external gamma dose rates, measured from radiophotoluminescent dosimeters (RPL) varied from 0.2 to 22 μGy h{sup -1} between sites. In parallel, the Total dose rates (TDR) absorbed by nematodes were predicted from measured soil activity concentrations, Dose Conversion Coefficients (DCC, calculated by the EDEN software) and Soil-to-biota concentration ratios (from the ERICA tool database). Results showed that TDR were one order of magnitude above the external gamma dose rate measured from RPL. This is mainly due to the contribution of alpha ({sup 241}Am,{sup 238,239,240}Pu) and beta ({sup 90}Sr, and {sup 137}Cs) emitters in the external dose rate. The small size (in the order of mm) of nematodes promoted a high energy deposition throughout the organisms without fading, giving more weight to external dose rate induced by alpha-and beta-emitters, relatively to gamma-emitters. Analysis of the nematode community showed a majority of bacterial-, plant-, and fungal- feeder nematodes and almost none of the disturbance sensitive families whatever the level of radioactive contamination. Multiple regression analysis was used to establish relationships between ecological features (nematodes abundance and family diversity, indices of ecosystem structure and function) to the environmental characteristics (TDR and soil physico-chemical properties). No evidence was found that nematode total abundance and family diversity were impaired by the radiological contamination. However, the Nematode Channel Ratio (defining the relative abundance of bacterial- versus fungal-feeding nematodes) decreased significantly with increasing TDR suggesting that the radioactive

    The current radiation level and its composition in aquatic ecosystems within the Chernobyl exclusion zone (ChEZ) are conditioned, above all things, by the amount of radioactive matters released as aerosols on a water surface and adjacent territories during the period of the active phase of the accident from destroyed of the Chernobyl NPP in 1986, and also by intensity and duration of the second processes of radionuclides washout from the catchment areas and hydrodynamic processes of their transport outside of water bodies. During last 10-15 years in the soils of the ChEZ the tendency of increase of yield of the mobile bioavailable forms of radionuclides, which released into hydrological systems with surface and ground waters or localized in the closed water systems, where quickly involving in the biotic cycle is marked. On the example of lakes of the Krasnensky flood plain of the Pripyat River, which is one of the most contaminated by radionuclides territory of the ChEZ, was determined that the basic amount of radionuclides in lake ecosystem is deposited in the bottom sediments: {sup 90}Sr - 89-95%, {sup 137}Cs - 99%, transuranium elements (TUE) {sup 238}Pu, {sup 239+240}Pu and {sup 241}Am - almost 100% of the total radionuclide amount in ecosystem. The increased migration activity of {sup 90}Sr determines its more high quantity in water (4-10%) on comparison with {sup 137}Cs (0.5-0.6%) and TUE (0.03-0.04%) and, opposite, less - in seston (0.15-0.16%) on comparison with {sup 137}Cs (0.25-0.30%). The value of {sup 90}Sr in biotic component amounts 0.25-0.61%, {sup 137}Cs - 0.14-0.47% and TUE - 0.07-0.16% of the total quantity in ecosystem. The gradual decline of radionuclide specific activity is a dominant tendency in the dynamics of {sup 137}Cs and {sup 90}Sr in water and aquatic biota of the majority of reservoirs and water flow in the ChEZ. The exception is water bodies, located on the dammed territories of the Krasnensky flood plain, where at the proceeding

    Interaction between charged surfaces in aqueous solution is a fundamental feature of colloid science. Theoretically, surface potential falls to half its value at a distance equal to a Debye length, which is typically on the order of tens to hundreds of nanometers. This potential prevents colloids from aggregating. On the other hand, long-range surface effects have been frequently reported. Here we report additional long-range effects. We find that charged latex particles in buffer solutions are uniformly excluded from several-hundred-micron-thick shells surrounding ion-exchange beads. Exclusion is observed whether the beads are charged similarly or oppositely to the particles. Hence, electrostatic interactions between bead and microsphere do not cause particle exclusion. Rather, exclusion may be the consequence of water molecules re-orienting to produce a more ordered structure, which then excludes the particles. PMID:19185312

    Cooperation between the social and natural sciences has become essential in order to encompass all the dimensions of coastal zone management. Socio-economic approaches are increasingly recommended to complement integrated assessment in support of these initiatives. A systematic review of the academic literature was carried out in order to analyze the main types of socio-economic assessments used to inform the coastal zone management process as well as their effectiveness. A corpus of 1682 articles published between 1992 and 2011 was identified by means of the representative coverage approach, from which 170 were selected by applying inclusion/exclusion criteria and then classified using a content analysis methodology. The percentage of articles that mention the use of socio-economic assessment in support of coastal zone management initiatives is increasing but remains relatively low. The review examines the links between the issues addressed by integrated assessments and the chosen analytical frameworks as well as the various economic assessment methods which are used in the successive steps of the coastal zone management process. The results show that i) analytical frameworks such as 'risk and vulnerability', 'DPSIR', 'valuation', 'ecosystem services' and 'preferences' are likely to lead to effective integration of social sciences in coastal zone management research while 'integration', 'sustainability' and 'participation' remain difficult to operationalize, ii) risk assessments are insufficiently implemented in developing countries, and iii) indicator systems in support of multi-criteria analyses could be used during more stages of the coastal zone management process. Finally, it is suggested that improved collaboration between science and management would require that scientists currently involved in coastal zone management processes further educate themselves in integrated assessment approaches and participatory methodologies.

    An increase in the planning and environmental restrictions associated with wind energy has led to a growth in interest towards wave energy. However, as the connection cost of a wave energy development is a driving factor in the development's feasibility, existing wind farm cable-routing techniques used by renewable energy developers may not be satisfactory. A Geographical Information System (GIS) method is presented which optimises the cable route between a wave farm and the electricity network, while taking a range of exclusion zones, such as native vegetation, into account. The optimisation is presented for a South Australian study area, which subsequently showed that exclusion zones reduce the number of suitable locations for wave energy by almost 40%. The method presented also assesses the effect that each exclusion zone applied has upon the number of suitable locations within the study area. The analysis undertaken showed that National Parks and cliffs pose a significant limitation to the potential of a wave energy industry within South Australia. Allowing the transmission route to travel through a National Park, or traverse a cliff, resulted in an increase in the number of locations from which a connection could be made to the electricity grid for less than $10 million of 33% and 50%, respectively. Conservation Parks, Wilderness Areas and native vegetation also have an effect upon the number of suitable locations for wave energy within South Australia. The GIS methods developed may be of assistance to governments in setting appropriate marine renewable energy policy, and also in identifying existing policy which may require amending if the government wishes to pursue and support the development of wave energy

  18. Radioactive Waste Management In The Chernobyl Exclusion Zone - 25 Years Since The Chernobyl Nuclear Power Plant Accident

    2011-01-01

    Radioactive waste management is an important component of the Chernobyl Nuclear Power Plant accident mitigation and remediation activities of the so-called Chernobyl Exclusion Zone. This article describes the localization and characteristics of the radioactive waste present in the Chernobyl Exclusion Zone and summarizes the pathways and strategy for handling the radioactive waste related problems in Ukraine and the Chernobyl Exclusion Zone, and in particular, the pathways and strategies stipulated by the National Radioactive Waste Management Program. The brief overview of the radioactive waste issues in the ChEZ presented in this article demonstrates that management of radioactive waste resulting from a beyond-designbasis accident at a nuclear power plant becomes the most challenging and the costliest effort during the mitigation and remediation activities. The costs of these activities are so high that the provision of radioactive waste final disposal facilities compliant with existing radiation safety requirements becomes an intolerable burden for the current generation of a single country, Ukraine. The nuclear accident at the Fukushima-1 NPP strongly indicates that accidents at nuclear sites may occur in any, even in a most technologically advanced country, and the Chernobyl experience shows that the scope of the radioactive waste management activities associated with the mitigation of such accidents may exceed the capabilities of a single country. Development of a special international program for broad international cooperation in accident related radioactive waste management activities is required to handle these issues. It would also be reasonable to consider establishment of a dedicated international fund for mitigation of accidents at nuclear sites, specifically, for handling radioactive waste problems in the ChEZ. The experience of handling Chernobyl radioactive waste management issues, including large volumes of radioactive soils and complex structures

    In 1986-1987, a set of experimental sites for studies of vertical migration of radionuclides released from the ChNPP was established in the ChNPP Exclusion Zone for various fallout plumes. The sites were selected considering local terrain and geo-chemical conditions, as well as physical and chemical characteristics of the fallout. The experimental sites included grasslands, and pre-Chernobyl cultivated meadows and croplands. Vertical migration of radionuclides in the ChNPP Exclusion Zone grasslands was evaluated. Parameters of 137Cs, 90Sr, and 239,240Pu transfer were calculated and the periods during which these radionuclides reach their ecological half-life in the upper 5 cm soil layer were estimated. Migration capabilities of these radionuclides in the grassland soils tend to decrease as follows: 90Sr >137Cs ≥ 239,240Pu. A significant retardation of the 137Cs vertical migration was shown in the grasslands long after the Chernobyl accident. During the 21st year after the fallout, average Tecol values for 137Cs (the period of time it takes in the environment for 137Cs to reach half the value of its original concentration in the upper 5 cm soil layer, regardless of physical decay) are as follows: 180 - 320 years for grassland containing automorphous mineral soils of a light granulometric composition; and 90 - 100 years for grassland containing hydromorphous organogenic soils. These values are significantly higher than those estimated for the period of 6-9 years after the fallout: 60 - 150 years and 11 - 20 years, respectively. The absolute 137Cs Tecol values are by factors of 3-7 higher than 137Cs radiological decay values long after the accident. Changes in the exposure dose resulting from the soil deposited 137Cs only depend on its radiological decay. This factor should necessarily be considered for development of predictive assessments, including dose exposures for the hypothetical population in case of their re-evacuation to the exclusion areas. The obtained

    The radioactive fission product 90Sr has a long biological half-life (˜18 y) in the human body. Due to its chemical similarity to calcium it accumulates in bones and irradiates the bone marrow, causing its high radio-toxicity. Assessing 90Sr is therefore extremely important in case of a nuclear disaster. In this work 16 soil samples were collected from the exclusion zone (background, stemming from global fallout due to the atmospheric nuclear weapon tests. Correlation analysis between 90Sr and 137Cs activity concentrations provides a potentially powerful tool to discriminate background 90Sr level from its Fukushima contribution.

    Biogenic carry-over of 90 Sr and 137 Cs by structural elements of exclusion zone's meadows and lea land phytocenosis is considered. Quantitative parameters of radionuclide accumulation are evaluated in substrate and live biomass of communities growing under various ecological conditions. It was stated that accumulation levels for ground biomass of communities depends, at a significant rate, on landscape growing conditions. These values fluctuate within the range of around 100 times. For 90 Sr, significantly lower difference in carry-over values was observed totaling up to 5 times, although for single community, this radionuclide carry-over exceeds essentially 137 Cs carry-over

    Stocks of radionuclides in natural and technogenic objects of a Zone (forests, meadows, former agricultural lands, water objects etc., object 'Shelter', Sites of Radioactive Waste Disposal (SRAWD) and Sites of Temporary Localization of Radioactive Waste (STLRAW)) are estimated. The estimations of fluxes of radionuclides both inside a Zone and out of its borders in normal conditions as well as in case of different natural and technogenic cataclysms (floods, fires, emergencies etc.) with account of probabilities of such events are discussed. The significance of the main fluxes of radionuclide migration beyond the Zone borders is estimated: a surface water flux (river Pripyat), air (wind) transfer, biogenic flux, technogenic migration. The significance of the non-radiological factors influenced on the ecological situation in a Zone (phyto-and zoosanitary, sanitary-epidemiological conditions) is discussed. The problems of irradiation of vegetation and animal organisms in terrestrial and water ecosystems, of personnel and people living on a Zone territory without permission (so called 'self-settlers') are considered. The priority directions of activities for control over the radiological and ecological situation on the territory and in objects of a Zone are formulated. (author)

    Pulsating bubbles have proved to be a versatile tool for trapping and sorting particles. In this article, we investigate the different streaming patterns that can be obtained with a group of bubbles in a confined geometry under ultrasound. In the presence of an external flow strong enough to oppose the streaming velocities but not drag the trapped bubbles, we observe either the appearance of exclusion zones near the bubbles or asymmetric streaming patterns that we interpret as the superposition of a two-dimensional (2D) streaming function and of a potential flow. When studying a lattice of several bubbles, we show that the streaming pattern can be accurately predicted by superimposing the contributions of every pair of bubbles present in the lattice, thus allowing one to predict the sizes and the shapes of exclusion zones created by a group of bubbles under acoustic excitation. We suggest that such systems could be used to enhance mixing at a small scale or to catch and release chemical species initially trapped in vortices created around bubble pairs.

    Full text: In this work a general procedure of establishment the criterion of complete release from regulatory control via the density of radioactive contamination of soil of alone areas of the Chornobyl exclusion zone is represented by the following three stages, namely: 1) Justification of the dose criterion of complete release by applying the fundamental approaches of regulating the prolonged exposure of the public on a basement of ICRP Publication No. 82; 2) Justification of a procedure for establishment of dose constraint through evaluation of the statistical distribution of a controlled radiation value through determination of the high boundary of the confidence interval; 3) Generalization of conversion coefficients (via the density of radioactive contamination of soil) and coverage coefficients for the dose forming factors of the public (inhalation intake of transuranium radionuclides both at natural and technogenic dust resuspension, peroral intake of 137 Cs and 90 Sr via food stuff, external exposure from 137 Cs); on a basis of these coefficients average doses and dose constraint of a critical group of the public are calculated. As it is shown in the work, the generalized criterion of complete release from regulatory control via the density of radioactive contamination of soil of the Chornobyl exclusion zone can be defined by dividing the recommended ICRP dose clearance level for situation of the post-accidental prolonged exposure of a critical group of the public, namely, 0.3 mSv·year -1 to the dose conversion coefficient (i.e. transfer from the superficial soil contamination of radioactivity to the dose constraint for the Chornobyl exclusion zone), namely, 12.9 μSv·year -1 /((kBq·M -2 ). Thus, a level of the density of radioactive contamination of soil, that provides the complete release from regulatory control makes 23.3 kBq·M -2 .

    Regional eco-environmental quality is the key and foundation to the sustainable socio-economic development of a region. Eco-environmental quality assessment can reveal the capacity of sustainable socio-economic development in a region and the degree of coordination between social production and the living environment. As part of a new development strategy for Fujian Province, the Western Taiwan Straits Economic Zone (hereafter referred to as the Economic Zone) provides an important guarantee for the development of China's southeastern coastal area. Based on ecological and remote sensing data on the Economic Zone obtained in 2000, 2005, and 2010, this study investigated county-level administrative regions with a comprehensive index of eco-environmental indicators. An objective weighting method was used to determine the importance of each indicator. This led to the development of an indicator system to assess the eco-environmental quality of the economic zone. ArcGIS software was used to assess the eco-environmental quality of the economic zone based on each indicator. The eco-environmental quality index (EQI) of the county-level administrative regions was calculated. The overall eco-environmental quality of the Economic Zone during the period studied is described and analyzed. The results show that the overall eco-environmental quality of the Economic Zone is satisfactory, but significant intraregional differences still exist. The key to improving the overall eco-environmental quality of this area is to restore vegetation and preserve biodiversity.

    Investigations of seasonal feed choice of a wild boar have been carried out during a 3-year period on the basis of the stomach content. Results of the investigations are given. A list of forage plants and forage animals is presented. Seasonal intensity of their consumption is evaluated. Main plant assemblages of the exclusion zone of the Chernobyl accident are analyzed for their significance in the diet of a wild boar. Special attention is paid to the role of underground forage (35% of average annual forage), and to consumption of Oenotera biennis roots comprising 26% of average annual forage. Recent state of the forage base and of the wild boar population is estimated. An attempt to predict its dynamics for the nearest 10-15 years is made

    Using sexually active rats for experiments the influence of chronic combined internal and external irradiation at low doses on sexual behavior and fertility of sexual active animals keeping within the 30-km Chernobyl external zone studied. After the 1.5 month consumption of drinking water containing radionuclides of natural Chernobyl spectrum the decrease in proportion of sexually active animals and suppression sexual motivation and erection were observed. This deviations resulted in the reducing of the inseminated females number. Dependence between the magnitude of total absorbed dose and the function of the sexual behavior regulatory mechanisms was obtained. In addition, the reduction of rat fertility took place because of the increase of preimplantation, but not post-implantation death in clean females coupled with irradiated males. Irradiation of males at total absorbed dose to gonads 0.23 c Gy decreased the fertility because of sexual behavior disturbance, and this effect was intensified by negative influence of ionizing radiation in the range of 0.7-7.0 c Gy on male gametes [ru

    In Ukraine, at the Vector site in the Chernobyl exclusion zone, it is planned to dispose of large amounts of radioactive wastes, including those of Chernobyl origin, containing transuranium elements. The paper analyzes the main possible scenarios of radiological impacts of the Vector site for a long-term period after expiration of its active administrative control taking into account location of the Vector site in the exclusion zone. In the paper, assessment of total activities that can be disposed of on site is demonstrated, based on non-exceeding of admissible radiological impacts. (orig.)

    Full Text Available This paper addresses a special zone design problem for economic census investigators that is motivated by a real-world application. This paper presented a heuristic multikernel growth approach via Constrained Delaunay Triangulation (CDT. This approach not only solved the barriers problem but also dealt with the polygon data in zoning procedure. In addition, it uses a new heuristic method to speed up the zoning process greatly on the premise of the required quality of zoning. At last, two special instances for economic census were performed, highlighting the performance of this approach.

  12. Expedition to the 30-km Chernobyl Exclusion Zone and the Utilization of its Experience in Education and Communication

    Between May 28 - June 4, 2005, under the organization of the Hungarian Nuclear Society (HNS) and the Hungarian Young Generation Network (HYGN) - which operates within the framework of the HNS - a scientific expedition visited the Chernobyl Nuclear Power Plant and the surrounding exclusion zone. The participants were young Hungarian nuclear professionals supervised by more experienced experts. The main scientific goals of the expedition were the followings: Get personal experiences in a direct way about the current status of the Chernobyl Power Plant and its surroundings, the contamination of the environment and about the doses. Gather information about the state of the shut down power plant and the shelter built above the damaged 4. unit. Training of young nuclear experts by performing on site measurements. The Hungarian expedition successfully achieved its objectives by performing wide-range of environmental and dosimetric measurements and collecting numerous biological and soil samples. Within the 30-km exclusion zone the influence of the accident occurred 20 years ago still could be measured clearly; however the level of the radioactivity is manageable in most places. The dosimetric measurements showed that no considerable exposure occurred among the members of the expedition. The analysis of samples has been started at the International Chernobyl Center in Slavutich. During the expedition not only environmental sampling and in-situ measurements were carried out but it was also well documented with photos and video recordings for educational, training and PR purposes. A documentary TV film was recorded during the expedition. The first-hand knowledge acquired during the expedition helps the authentic communication of the accident and its present-day consequences, which is especially important in 2006, 20 years after the Chernobyl accident. Since Ukraine and Hungary are neighbor countries the media constantly discuss the accident, the consequences and the risks of

    A study on (137)Cs, (40)K, (226)Ra, (228)Ra, and (238)U was carried out along the EEZ of Qatar. Results serve as the first ever baseline data. The level of (137)Cs (mean value 1.6 ± 0.4 Bq m(-3)) in water filters was found to be in the same order of magnitude as reported by others in worldwide marine radioactivity studies. Results are also in agreement with values reported from other Gulf regions. The computed values of sediment-water distribution coefficients Kd, are lower than the values given by IAEA. Measurements were carried out for bottom sediments, biota samples like fish, oyster, sponge, seashell, mangrove, crab, shrimp, starfish, dugong and algae. The 'concentration factors' reported for biota samples are below the levels published by IAEA and cause no significant impact on human health for seafood consumers in Qatar.

    A preliminary survey was performed for forest areas within the exclusion zone around the Fukushima Daiichi Nuclear Power Plant, for radionuclide contamination levels and radiation effects on trees during the first year after the March 2011 accident. Even in the most contaminated forest, approximately 3 km west of the power plant, no externally visible symptoms of radiation damage—including yellowing, malformation, and early withering of leaves—were observed in trees, indicating that massive radiation damage did not occur in the surrounding forests after the accident. Radiosensitive coniferous plants were, however, heavily contaminated by the deposition of radionuclides in reproductive organs such as cones, which could cause the exposure of developing seeds. The level of radionuclides in the cones of Japanese cedar trees changed, depending on the contamination level of the forest, which was approximately given by an ambient dose rate. The dose rate of internal exposure in the cones of the most contaminated forest, which was calculated to include exposure from the radionuclides deposited in the organs, was found to be within the criteria dose rate of 4-40 μGy/h selected for pine trees by the ICRP in Publication 108. This raises the necessity of performing more detailed analyses of the cytogenetic and reproductive damage to forest trees in the area. (author)

    Changes of faunal composition of insects-hortobionts and longterm dynamics of species diversity in the Chernobyl exclusion zone biotopes is studied. It is shown that on despite of the continuing fluctuations in species diversity, which may be associated with the process of long-term dynamics of the number of species, there was a clear trend to increasing abundance of species of insects. In evolutionary terms the settlement of harmful populations in natural habitats should be considered as the primary groupings as opposed to the secondary - on agricultural crops. For these groupings there are different vectors of selection: in the first case - naturally, in the second - artificial under the influence of anthropogenic factors. Different types of selection lead to the formation of different structures of phenotypic groupings and, accordingly, of their physiological characteristics. With the competitive process, biological regulation, nutrition by plants with natural resistance, the primary groupings acquire the genetic diversity, generalized type of nutrition and high viability. In secondary groupings, the vector of selection is aimed at high reproductive potential, due to the specialized type of nutrition by cultural plants that have much higher energy value than natural.

  8. CHRONIC IRRADIATION OF SCOTS PINE TREES (PINUS SYLVESTRIS) IN THE CHERNOBYL EXCLUSION ZONE: DOSIMETRY AND RADIOBIOLOGICAL EFFECTS

    Energy Technology Data Exchange (ETDEWEB)

    Farfan, E.; Jannik, T.

    2011-10-01

    To identify effects of chronic internal and external radiation exposure for components of terrestrial ecosystems, a comprehensive study of Scots pine trees in the Chernobyl Exclusion Zone was performed. The experimental plan included over 1,100 young trees (up to 20 years old) selected from areas with varying levels of radioactive contamination. These pine trees were planted after the 1986 Chernobyl Nuclear Power Plant accident mainly to prevent radionuclide resuspension and soil erosion. For each tree, the major morphological parameters and radioactive contamination values were identified. Cytological analyses were performed for selected trees representing all dose rate ranges. A specially developed dosimetric model capable of taking into account radiation from the incorporated radionuclides in the trees was developed for the apical meristem. The calculated dose rates for the trees in the study varied within three orders of magnitude, from close to background values in the control area (about 5 mGy y{sup -1}) to approximately 7 Gy y{sup -1} in the Red Forest area located in the immediate vicinity of the Chernobyl Nuclear Power Plant site. Dose rate/effect relationships for morphological changes and cytogenetic defects were identified and correlations for radiation effects occurring on the morphological and cellular level were established.

  10. Transcriptional Upregulation of DNA Damage Response Genes in Bank Voles (Myodes glareolus Inhabiting the Chernobyl Exclusion Zone

    2018-01-01

    Full Text Available Exposure to ionizing radiation (IR from radionuclides released into the environment can damage DNA. An expected response to exposure to environmental radionuclides, therefore, is initiation of DNA damage response (DDR pathways. Increased DNA damage is a characteristic of many organisms exposed to radionuclides but expression of DDR genes of wildlife inhabiting an area contaminated by radionuclides is poorly understood. We quantified expression of five central DDR genes Atm, Mre11, p53, Brca1, and p21 in the livers of the bank vole Myodes glareolus that inhabited areas within the Chernobyl Exclusion Zone (CEZ that differed in levels of ambient radioactivity, and also from control areas outside the CEZ (i.e., sites with no detectable environmental radionuclides in Ukraine. Expression of these DDR genes did not significantly differ between male and female bank voles, nor among sites within the CEZ. We found a near two-fold upregulation in the DDR initiators Mre11 and Atm in animals collected from the CEZ compared with samples from control sites. As Atm is an important regulator of oxidative stress, our data suggest that antioxidant activity may be a key component of the defense against exposure to environmental radioactivity.

    Self-purification of closed water bodies within the Chernobyl exclusion zone (EZ) is an extremely slow process. Therefore, ecosystems of the majority of lakes, dead channels and crawls possess high levels of radionuclide contamination of all components. Along with natural decontamination processes in aquatic ecosystems such as physical decay of radionuclides and their water transport outside the EZ, there is a change of physical and chemical forms of radioactive substances in soils of catchment areas, their transformation and transition in the mobile and bioavailable state, washout to the closed aquatic ecosystems and accumulation by hydrobionts. This essentially deteriorates the radiation situation in closed aquatic ecosystems, which are some kind of 'storage system' of radioactive substances in the EZ and results in increase of radiation dose to aquatic species and manifests in a variety of radiation effects at different levels of biological systems. We established dose-related effects in hydrobionts of lakes within the EZ which indicates a damage of biological systems at subcellular, cellular, tissue, organ, organism and population levels as a result of chronic exposure to low doses of ionizing radiation. The rate of chromosomal aberrations in cells of aquatic species, many-a-times exceeds the level of spontaneous mutagenesis level to aquatic biota. Increased levels of chromosome damages may be a manifestation of radiation-induced genetic instability, which is one of the main mechanisms for the protection of living organisms from exposure to stressors with subsequent implementation at higher levels of organization of biological systems.

    Full Text Available We hypothesize a mechanistic model of how negatively-charged exclusion zones (EZs are created. While the growth of EZs is known to be associated with the absorption of ambient photonic energy, the molecular dynamics giving rise to this process need greater elucidation. We believe they arise due to the formation of oxy-subhydride structures (OH−(H2O4 with a tetrahedral (sp3 (OH−(H2O3 core. Five experimental data sets derived by previous researchers were assessed in this regard: (1 water-derived EZ light absorbance at specific infrared wavelengths, (2 EZ negative potential in water and ethanol, (3 maximum EZ light absorbance at 270 nm ultraviolet wavelength, (4 ability of dimethyl sulphoxide but not ether to form an EZ, and (5 transitory nature of melting ice derived EZs. The proposed tetrahedral oxy-subhydride structures (TOSH appear to adequately account for all of the experimental evidence derived from water or other polar solvents.

    Full Text Available This paper uses a regional perspective to analyse the progression of the risk of poverty or social exclusion (AROPE rate in Spain during the recent crisis period. Various methodological issues related to how the components of the AROPE rate are integrated have brought into question its suitability as the Europe 2020 strategy indicator. As these problems are accentuated in the analysis of individual territories, this paper examines the effect of using regional poverty thresholds. When these are included, the risk of poverty or social exclusion is more consistent with the standard of living enjoyed in each territory. In addition, this paper mainly on the poverty rate by the application of a multiple linear regression model. Nonetheless, the explanatory power of the deprivation and employment indicators diminishes when using regional poverty thresholds.

    This study addresses a significant data deficiency in the developing environmental protection framework of the International Commission on Radiological Protection, namely a lack of radionuclide transfer data for some of the Reference Animals and Plants (RAPs). It is also the first study that has sampled such a wide range of species (invertebrates, plants, amphibians and small mammals) from a single terrestrial site in the Chernobyl Exclusion Zone (CEZ). Samples were collected in 2014 from the 0.4 km 2 sampling site, located 5 km west of the Chernobyl Nuclear Power complex. We report radionuclide ( 137 Cs, 90 Sr, 241 Am and Pu-isotopes) and stable element concentrations in wildlife and soil samples and use these to determine whole organism-soil concentration ratios and absorbed dose rates. Increasingly, stable element analyses are used to provide transfer parameters for radiological models. The study described here found that for both Cs and Sr the transfer of the stable element tended to be lower than that of the radionuclide; this is the first time that this has been demonstrated for Sr, though it is in agreement with limited evidence previously reported for Cs. Studies reporting radiation effects on wildlife in the CEZ generally relate observations to ambient dose rates determined using handheld dose meters. For the first time, we demonstrate that ambient dose rates may underestimate the actual dose rate for some organisms by more than an order of magnitude. When reporting effects studies from the CEZ, it has previously been suggested that the area has comparatively low natural background dose rates. However, on the basis of data reported here, dose rates to wildlife from natural background radionuclides within the CEZ are similar to those in many areas of Europe. Copyright © 2018 The Authors.

    To avoid the coincidence between the tower nature frequency and rotational excitation frequency, a SEZ (speed exclusion zone) must be built for a two-blade wind turbine with a full rated converter. According to the literature, two methods of SEZ-crossing could be adopted. However, none of them have been studied in industrial applications, and their performance remains unclear. Moreover, strategies on power regulation operation are not covered. To fully investigate them, this paper develops two control systems for a two-blade WT (wind turbines) with a SEZ. Because control systems play vital roles in determining the performance of the WT, this paper focuses on comparative studies on their operation strategies and performance. In these strategies, optimal designs are introduced to improve existing SEZ algorithms. Moreover, to perform power regulation outside the SEZ, two operation modes are divided in the proposed down power regulation solutions. The developed control systems’ performance is confirmed by simulations and field tests. Two control systems present similar capabilities of power production and SEZ-bridging. Nevertheless, at the cost of significantly increased tower loads, one captures 1% more energy than the other. Overall consideration must be made for the control system selection for a WT with a SEZ. - Highlights: • Two control systems are developed for a two-blade WT with a SEZ. • Three strategies, that is, power optimization, power limitation and power regulation, are discussed. • Optimal designs are adopted to enhance the WT's SEZ-bridging capability. • Simple but effective power regulation solutions are presented. • Simulation and field test results show that Control System 2 produces 1% more energy at the cost of increased tower loads.

    Full Text Available Eco-environmental stress refers to the pressure borne by the environment in sustaining the pre-existing non-industrialized state and/or in counteracting adverse impacts caused by natural and human factors. The present article introduces the concept, research progress, and method for assessing eco-environmental stress. An eco-environmental stress index (ESI is established to assess the eco-environmental stress of 13 cities in the Western Taiwan Straits Economic Zone (hereafter referred to as the Economic Zone during the period from 2000 to 2010. The research provides a reference for the strategic planning of industrial development and environmental protection. The results show that the overall eco-environmental stress of the Economic Zone was slight and did not have significant change during the past 10 years. The cities with the most severe eco-environmental stress are distributed in the north and south of the Economic Zone. Most areas of Fujian Province have a low degree of eco-environmental stress, a situation that is being constantly improved. The regions with high atmospheric and water pollutant emissions are concentrated in the northern, middle, and southern coastal regions of the Economic Zone. The pollutant emissions of coastal cities are higher than those of inland cities. In the future, ecological restoration and compensation mechanisms should be established for regions where environmental protection and remediation is urgently needed.

    The uniqueness of the Chernobyl accident lies in the fact that so much radioactive material was discharged to the atmosphere as solid fuel particles from the reactor core. Between the 26 April and the 6 May 1986 more than 6 tons of small particles of highly radioactive uranium oxide fuel were discharged to the atmosphere and were responsible for more than 75 % of the radioactive contamination on the ground in the exclusion zone. In 1987, about 800 trenches had been dug in the exclusion zone to prevent re-suspension and to protect workers from contamination. In 1999, the IRSN, in collaboration with IGS and UIAR, equipped trench 22 (CPS) in order to monitor radionuclide migration in the environment (water, soil, plants). At the EPIC site high uranium concentrations were observed in the groundwater downstream from trench 22. We discuss the possible origins of this uranium 'plume'. (authors)

    Highlights: • Investigation on economic feasibility of PV/diesel system in various climatic zones. • HOMER is used to solve economic feasibility analysis. • By the sensitivity analysis, the net present cost is reduced. • Optimum climatic zone in Tamil Nadu, India is recommended. - Abstract: With the increasing threat to environment and the fast depleting fossil fuel resources, hybrid power systems consisting of two or more renewable energy sources such as solar PV, wind, biomass, ocean thermal-with or without the back up of diesel generator have come to the forefront. These hybrid systems are normally integrated with battery banks for total reliability; such systems have brought about better quality of life in remote areas of developing economics. The remote areas in the state of Tamil Nadu in India possess excellent renewable energy sources. These areas fall under different climatic zones, are sparsely populated and are in the process of development. Though these areas are connected to the grid, Tamil Nadu grid is not stable; it is currently experiencing 40% short fall in generation. Thus grid power is available to these remote areas only for 10 h a day and even when available, there are voltage frequency problems. This paper analyses the economic feasibility of installing and operating hybrid systems in these areas. The areas are divided into different climatic zones and the hybrid system economy is analyzed for each climatic zone on the basis of NPC (net present cost), consumption of diesel and renewable fraction for all climate zones. The analysis indicates that the interior climatic zone – the area would be the optimum climatic zone to install HPS PV/diesel. The sensitivity analysis proves that the NPC of such a system can be reduced. It is suggested that due to high initial cost, government subsidy is necessary to adopt the system on a large scale. Such a profit will encourage development of renewable energy utilization and bring about rapid

    Full Text Available This paper investigates the process of developing and implementing special economic zones (SEZs and industrial parks in Russia. Governments commonly use SEZ policies to develop and diversify exports, create jobs and launch technology/knowledge sharing. The industrial cluster concept is based on the significance of rivalry and supplier networks within the cluster, the combination of geographical specificities and government policies that lead to innovation and productivity growth. This study reveals that in Russia the government′s approach in developing these initiatives has strongly interfered with business activities and prevented the vital competitive and collaborative behavior of firms within these economic zones.

    The effects of spatial variability of hydraulic parameters and initial groundwater plume localization on the possible extent of groundwater pollution plumes have already been broadly studied. However, only a few studies, such as Kjeldsen et al. (1995), take into account the effect of source term spatial variability. We explore this question with the 90Sr migration modeling from a shallow waste burial located in the Chernobyl Exclusion Zone to the underlying sand aquifer. Our work is based upon groundwater sampled once or twice a year since 1995 until 2015 from about 60 piezometers and more than 3,000 137Cs soil activity measurements. These measurements were taken in 1999 from one of the trenches dug after the explosion of the Chernobyl nuclear power plant, the so-called "T22 Trench", where radioactive waste was buried in 1987. The geostatistical analysis of 137Cs activity data in soils from Bugai et al. (2005) is first reconsidered to delimit the trench borders using georadar data as a covariable and to perform geostatistical simulations in order to evaluate the uncertainties of this inventory. 90Sr activity in soils is derived from 137Cs/154Eu and 90Sr/154Eu activity ratios in Chernobyl hot fuel particles (Bugai et al., 2003). Meanwhile, a coupled 1D non saturated/3D saturated transient transport model is constructed under the MELODIE software (IRSN, 2009). The previous 90Sr transport model developed by Bugai et al. (2012) did not take into account the effect of water table fluctuations highlighted by Van Meir et al. (2007) which may cause some discrepancies between model predictions and field observations. They are thus reproduced on a 1D vertical non saturated model. The equiprobable radionuclide localization maps produced by the geostatistical simulations are selected to illustrate different heterogeneities in the radionuclide inventory and are implemented in the 1D model. The obtained activity fluxes from all the 1D vertical models are then injected in a 3D

    Full Text Available The advent of industrial economies coincides with the emergence of the economy as an autonomous discipline and with the question, not hitherto placed on the “value of nature”. As the basis of any theory of the first economists was the statement that every "value" is the work of man, was a fragile theoretical nature of the classics, since this is not the result of human labor. So, to circumvent the problem of fixing the "values​​" intrinsic to nature, environmental economics, in its most widespread version, part of the statement that assigns what is "value" is not exactly the environment or environmental resources but people's preferences in relation to changes in quality or quantity supplied of natural resource. The idea of ​​transaction rights on the environment (in fact, the right to pollute found resonance in the United States with "certified environmental" measures to better control pollution. They are traded for several polluting companies that can, in turn, trade them in the market for environmental permits. Remember that in any arrangement in which disputing parties settle in reaction conditions supposedly equal, makes a big difference the presence of those more able to lobby and power to influence public opinion. It is seen, even with the refinement that achieves economic analysis by incorporating as legitimate rights of non pollution, yet there is no guarantee the order of environmental damage if the whole issue be restricted to the context of the economic approach simply.

    From the earliest years after the Chernobyl accident in 1986 the radioecological study on freshwater plant communities in the water-bodies within the Chernobyl exclusion zone (ChEZ) has been held. At first stages it was the research on plant species collection and radionuclide contamination of aquatic ecosystems. Now, it is the seasonal monitoring with several groups of data deals with different areas of plant communities investigation: (1) the data characterized the level of radionuclides contamination of the abiotic and biotic components of phyto-coenosis and connected absorbed dose rates for various species of aquatic plants; (2) indexes of plant reproduction, including productivity, sterility, seed germination indexes and different abnormalities of ontogenesis; (3) indexes of morphological deviations (radiomorphoses) of aquatic plant's reproduction organs such as panicle and seeds; (4) cytogenetic indexes including the rate and spectrum of chromosome aberrations in cells of apical root meristem of air-aquatic plants; (5) the group of indexes, connected with plant's immunity. The calculated absorbed dose rate for littoral emergent plants in sampling water bodies was varied from 0.7 to 1.4 Gy/year in dependence of radioactive contamination of bottom sediments, plant tissues and level of gamma-background. There were registered rather low rate of plant productivity (hundred times lower than normal), high percentage of sterility (20-80%), low germinating ability (14-48 %) and germinating power (40-50%) of seeds from all sampling water bodies within the ChEZ. Against the general suppressed background the effect of relative stimulation of more affected seeds was observed. With increase of internal absorbed dose in range of 0.2-5.3 mGy/year the number of germinated seeds was increased. At the same time the number of different abnormalities of seeds was increased as well. The highest rate of the morphological damages (up to 25 % of the total number of

    Full Text Available Economic power dispatch (EPD is one of the main tools for optimal operation and planning of modern power systems. To solve effectively the EPD problem, most of the conventional calculus methods rely on the assumption that the fuel cost characteristic of a generating unit is a continuous and convex function, resulting in inaccurate dispatch. This paper presents the design and application of efficient adaptive differential evolution (ADE algorithm for the solution of the economic power dispatch problem, where the non-convex characteristics of the generators, such us prohibited operating zones and ramp rate limits of the practical generator operation are considered. The 26 bus benchmark test system with 6 units having prohibited operating zones and ramp rate limits was used for testing and validation purposes. The results obtained demonstrate the effectiveness of the proposed method for solving the non-convex economic dispatch problem.

    Full Text Available Results of purposeful groundwater monitoring and modelling studies are presented, which were carried out in order to better understand groundwater flow patterns from the “Vector” site for near-surface radioactive waste disposal and storage in the Chornobyl exclusion zone towards river network. Both data of observations at local-scale monitoring well network at “Vector” site carried out in 2015 - 2016 and modelling analyses using the regional groundwater flow model of Chornobyl exclusion zone suggest that the groundwater discharge contour for water originating from “Vector” site is Sakhan River, which is the tributary to Pripyat River. The respective groundwater travel time is estimated at 210 - 340 years. The travel times in subsurface for 90Sr, 137Cs, and transuranium radionuclides (Pu isotopes, 241Am are estimated respectively at thousands, tenths of thousands, hundreds of thousands – million of years. These results, as well as presented data of analyses of lithological properties of the geological deposits of the unsaturated zone at “Vector” site, provide evidence for good protection of surface water resources from radioactivity sources (e.g., radioactive wastes to be disposed in the near-sursface facilities at “Vector” site.

    2015-07-01

    This work concerns the study of the effects felt by a network as a whole when a specific node is perturbed. Many real world systems can be described by network models in which the interactions of the various agents can be represented as an edge of a graph. With a graph model in hand, it is possible to evaluate the effect of deleting some of its edges on the architecture and values of nodes of the network. Eventually a node may end up isolated from the rest of the network and an interesting problem is to have a quantitative measure of the impact of such an event. For instance, in the field of finance, the network models are very popular and the proposed methodology allows to carry out "what if" tests in terms of weakening the links between the economic agents, represented as nodes. The two main concepts employed in the proposed methodology are (i) the vibrational IC-Information Centrality, which can provide a measure of the relative importance of a particular node in a network and (ii) autocatalytic networks that can indicate the evolutionary trends of the network. Although these concepts were originally proposed in the context of other fields of knowledge, they were also found to be useful in analyzing financial networks. In order to illustrate the applicability of the proposed methodology, a case of study using the actual data comprising stock market indices of 12 countries is presented.

    Natural disasters of a geodynamic nature can cause enormous economic and human losses. The economic costs of a landslide disaster include relocation of communities and physical repair of urban infrastructure. However, when performing a quantitative risk analysis, generally, the indirect economic consequences of such an event are not taken into account. A probabilistic approach methodology that considers several scenarios of hazard and vulnerability to measure the magnitude of the landslide and to quantify the economic costs is proposed. With this approach, it is possible to carry out a quantitative evaluation of the risk by landslides, allowing the calculation of the economic losses before a potential disaster in an objective, standardized and reproducible way, taking into account the uncertainty of the building costs in the study zone. The possibility of comparing different scenarios facilitates the urban planning process, the optimization of interventions to reduce risk to acceptable levels and an assessment of economic losses according to the magnitude of the damage. For the development and explanation of the proposed methodology, a simple case study is presented, located in north-eastern zone of the city of Medellín. This area has particular geomorphological characteristics, and it is also characterized by the presence of several buildings in bad structural conditions. The proposed methodology permits to obtain an estimative of the probable economic losses by earthquake-induced landslides, taking into account the uncertainty of the building costs in the study zone. The obtained estimative shows that the structural intervention of the buildings produces a reduction the order of 21 % in the total landslide risk.

    Full Text Available Agriculture is the least profitable industry in China. However, even with large financial subsidies from the government, farmers’ living standards have had no significant impact so far due to the historical, geographical, climatic factors. The study examines and quantifies the net economic and environmental benefits by utilizing biochar as a soil amendment in eleven counties in the Poyang Lake Eco-Economic Zone. A nonparametric kernel regression model is employed to estimate the relation between the scaled environmental and economic factors, which are determined as regression variables. In addition, the partial linear and single index regression models are used for comparison. In terms of evaluations of mean squared errors, the kernel estimator, exceeding the other estimators, is employed to forecast benefits of using biochar under various scenarios. The results indicate that biochar utilization can potentially increase farmers’ income if rice is planted and the net economic benefits can be achieved up to ¥114,900. The net economic benefits are higher when the pyrolysis plant is built in the south of Poyang Lake Eco-Economic Zone than when it is built in the north as the southern land is relatively barren, and biochar can save more costs on irrigation and fertilizer use.

    Full Text Available This study seeks to empirically explore the impact of key monetary policy variables on the economic growth in the CEMAC zone from the period of 1981 to 2015. Carried out using the Ex post facto research design based on the principal components selection approach, the study interacts money supply, interest rate, economic growth, and inflation rate, among themselves and their lagged values using the Vector Auto-regressive (VAR analytical technique. The Classical quantity theory of money, the Cambridge Cash Balanced, the liquidity preference theory and the Monetarists as theoretical frameworks were explored to appreciate the time trends of the selected variables on the economic growth of the CEMAC zone. Based on the (VAR methodology, the study reveals that key monetary policy variables influence economic growth of the CEMAC zone in different ways with inflation rate as the impact factor. On the basis of the above findings and the evidence from other studies, lending and inflation rate generated substantial destabilizing impacts on the economic growth, suggesting that the monetary authorities should play a critical role in creating an enabling environment for growth. The determination of the optimal lending rate should reflect the overall internal rate of returns in the productive sectors with due attention to market fundamentals. In line with this, the Central Bank of CEMAC should be given complete instrumental autonomy to operate depending on a set of in-built targets by the individual countries of the zone. Effective monetary targeting and accommodating monetary policies should be designed and implemented as the need arises with little or no political motives.

    With the development of the society and economy, the contradictions among population, resources and environment are increasingly worse. As a result, the capacity of resources and environment becomes one of the focal issues for many countries and regions. Through investigating and analyzing the present situation and the existing problems of resources and environment in Poyang Lake Eco-economic Zone, seven factors were chosen as the evaluation criterion layer, namely, land resources, water resources, biological resources, mineral resources, ecological-geological environment, water environment and atmospheric environment. Based on the single factor evaluation results and with the county as the evaluation unit, the comprehensive capacity of resources and environment was evaluated by using the state space method in Poyang Lake Eco-economic Zone. The results showed that it boasted abundant biological resources, quality atmosphere and water environment, and relatively stable geological environment, while restricted by land resource, water resource and mineral resource. Currently, although the comprehensive capacity of the resources and environments in Poyang Lake Eco-economic Zone was not overloaded as a whole, it has been the case in some counties/districts. State space model, with clear indication and high accuracy, could serve as another approach to evaluating comprehensive capacity of regional resources and environment.

    In the Chernobyl exclusion zone forest trees have to tolerate and to adapt to ionizing radiation, therefore the molecular basis of their adaptive responses is of the utmost interest. Based on SNP analysis and real time PCR nucleotide diversity and expression profiles of gene fragments of catalase (Cat) and glutathione peroxidase (GPx), which are known as radical scavenging genes, were analysed in the needles of irradiated pine trees of the Chernobyl exclusion zone. In acutely and chronically irradiated trees (50 years old) planted before the accident a higher nucleotide diversity of Cat and more somatic mutations were found compared to their control. Chronically irradiated trees (20 years old) planted after the accident showed a similar nucleotide diversity of Cat compared to their control and in both collectives one somatic mutation was found. The nucleotide diversity of GPx was higher in all analysed trees compared to Cat. No somatic mutation events were found in GPx. For both gene fragments, no association between the received dose in a tree and the nucleotide diversity and mutation events was detected. The expression profiles of Cat and GPx in acutely and chronically and in chronically irradiated trees were similar. Compared to their corresponding control collectives, Cat was up-regulated and GPx slightly down-regulated.

    Ecosystems offer material and environmental support for human habitation and development in those areas of the earth where people choose to live. However, urbanization is an inexorable trend of human social development and threatens the health of those ecosystems inhabited by humans. This study calculates the values of NPP (net primary productivity), carbon sequestration, water interception, soil conservation, and agricultural production in the Guanzhong-Tianshui Economic Zone. At the same time, we combined DMSP/OLS (Defense Meteorological Satellite Program Operational Line Scanner) night lights remote sensing data and statistical data to analyze the level of urbanization. Quantitative analysis was performed on the interactions between the ecosystem service functions and urbanization based on the calculations of their coupled coordination degrees. The results were the following: (1) The values of NPP, carbon sequestration, and agricultural production showed a trend of increase. However, water interception decreased before increasing, while soil conservation showed the reverse trend; (2) Urbanization levels in the Guanzhong-Tianshui Economic Zone for the last 10 years have proceeded at a fast pace with comprehensive promotion; and (3) Coupled and coupled coordination degrees between urbanization and ecosystem services show increasing trends. This research can provide a theoretical basis for the region's rapid economic development in the balance.

    Full Text Available Results of comparative cytogenetical examination of two groups are presented. First group is staff from two workshops (RAW management and RAW deactivation of SJE “Complex” in Chornobyl exclusion zone. Second group consists of the persons who had no mutagenic factors influence during their professional activity (condi-tional control. Classical chromosome analysis method was used. It was found chromosome damages frequency in staff is significantly higher than spontaneous level in conditional control group. Professional experience dura-tion and external exposure integral doses of both workshops staff do not differ. Staff of RAW deactivation work-shop, who is additionally influenced by chemical and physical factors, has significantly higher chromosome ab-erration frequency, particularly due to specific cytogenetical markers of exposure. Correlation between external exposure integral doses and total chromosome aberration frequency, chromosome type aberration frequency, stabile interchromosomal exchanges frequency was found.

    Protected species are the focus of many radiological environmental assessments. However, the lack of radioecological data for many protected species presents a significant international challenge. Furthermore, there are legislative restrictions on destructive sampling of protected species to obtain such data. Where data are not available, extrapolations are often made from 'similar' species but there has been little attempt to validate this approach. In this paper we present what, to our knowledge, is the first study purposefully designed to test the hypothesis that radioecological data for unprotected species can be used to estimate conservative radioecolgical parameters for protected species; conservatism being necessary to ensure that there is no significant impact. The study was conducted in the Chernobyl Exclusion Zone. Consequently, we are able to present data for Pu isotopes in terrestrial wildlife. There has been limited research on Pu transfer to terrestrial wildlife which contrasts with the need to assess radiation exposure of wildlife to Pu isotopes around many nuclear facilities internationally. Our results provide overall support for the hypothesis that data for unprotected species can be used to adequately assess the impacts for ionising radiation on protected species. This is demonstrated for a range of mammalian and avian species. However, we identify one case, the shrew, for which data from other ground-dwelling small mammals would not lead to an appropriately conservative assessment of radiation impact. This indicates the need to further test our hypothesis across a range of species and ecosystems, and/or ensure adequate conservatism within assessments. The data presented are of value to those trying to more accurately estimate the radiation dose to wildlife in the Chernobyl Exclusion Zone, helping to reduce the considerable uncertainty in studies reporting dose-effect relationships for wildlife.

    Full Text Available At the end of seventies, Deng Xioaping, President applied a modernization policy in China, that during more than 30 years allow to reach high economic growth rates above 8% average per year. This reform included the instauration of four Special Economic Zones (SEZ in the southeast of the country, three in Guangdong (Shenzhen, Zhuhai and Shantao and one in Xiamen, Fujian.The purpose of this paper is to analyze the backgrounds of SEZ, the reasons of Chinese Government to implement its and the positive impacts and barriers to become operational.The conclusion in this article is that sez arise like an experiment of the Chinese central government economic policy to apply capitalist measures in design previous regions, the most important benefit has been the strong attraction of Foreing Direct Investment, explained in a surplus trade balance, sustanaible economic growht and technological transference. However, the most significative operational barrier has been the legal rigidity in the imported overseas products, a change of nacional politicideology system and problem asociated with burocracy and corruption.

    Large-scale ecological patches play an important role in regional biodiversity conservation. However, with the rapid progress of China's urbanization, human disturbance on the environment is becoming stronger. Large-scale ecological patches will degrade not only in quantity, but also in quality, threatening the connections among them due to isolation and seriously affecting the biodiversity protection. Taking Poyang Lake Eco-economic Zone as a case, this paper established the potential ecological corridors by minimum cost model and GIS technique taking the impacts of landscape types, slope and human disturbance into consideration. Then, based on gravity quantitative model, we analyzed the intensity of ecological interactions between patches, and the potential ecological corridors were divided into two classes for sake of protection. Finally, the important ecological nodes and breaking points were identified, and the structure of the potential ecological network was analyzed. The results showed that forest and cropland were the main landscape types of ecological corridor composition, interaction between ecological patches differed obviously and the structure of the composed regional ecological network was complex with high connectivity and closure. It might provide a scientific basis for the protection of biodiversity and ecological network optimization in Poyang Lake Eco-economic Zone.

    The Institute for Radiation Protection and Nuclear Safety (IRSN) has managed (1999-2003) the Chernobyl Pilot Site Project (CPS project) in collaboration with the Ukrainian Institute of Agricultural Radiology (UIAR), the Institute of Geological Sciences (IGS) and the Tracer Application Section (CEA/SAT). The special focus of the CPS project was environmental behavior and radionuclide release mechanisms from dispersed nuclear fuel particles, forming radionuclide migration source-term. So, the contaminated environment was used as an open-sky laboratory to develop site characterization techniques, better understand and model processes of radionuclides migration in soils and geological environment. The CPS project resulted in detailed characterization of site geology structure, hydrogeology regime, hydro-dispersion regime in the aquifer and unsaturated zone, radionuclide inventory and distribution in trench no.22, focused at 137 Cs and 90 Sr. The special research program using scanning electron microscopy and sequential extraction analytical techniques was devoted to characterization of fuel particles and quantification of their dissolution behavior. It was established that Chernobyl radionuclides are associated with uranium oxide matrix particles of different degree of oxidation, characterized by different dissolution rates, as well as with non-dissolvable zirconium containing matrix particles. The multi-component fuel particles dissolution model with empirical dissolution rate constants was developed to describe the source-term. The methodology for radionuclide transport was based on application of the classical advection-diffusion equation and utilization of effective transport parameters. The developed so far modeling methodology is mostly suited for producing spatially averaged parameter values (such as radionuclide concentrations in trench porous solution, and/or integral radionuclide release to aquifer), and for long-term predictions on a scale of years and

  7. SUSTENABLE DEVELOPMENT OF THE ROMANIAN ECONOMY BY ADOPTING THE CHINESE MODEL OF SPECIAL ECONOMIC ZONES

    2011-12-01

    Full Text Available The architecture of the Chinese economy began to take shape in the late 1980's, because of the new reforms that the Chinese Communist Party started to take. With the death of Mao Zedong in 1976, the Chinese leadership is taken by Deng Xiaoping, who stated a blitz course in capitalism. The new president encouraged foreign direct investments by creating special economic zones near the costal cities, were foreign companies obtained several tax brakes and other incentives, only to invest in those regions. With the help of statistical data from WTO, IMF, and the World Bank, the current paper analyzes the impact of these special economic zones on the Chinese economy, raging from mutations in the labor market and economic sectors structure and their evolution in the formation of the GDP, FDI inflows, and last but not least external trade and current account situation. On the other hand, the paper tries to make a connection with Romania, computing and predicting, based on the Chinese figures, the way in which the Romanian economy, by creating four economic zones within the counties of Satu Mare, Bihor, Arad, and Constanta, will be able to experience the same growth. The first three counties have been piked up based on their proximity to the Schengen area, and/or on their infrastructure, plain terrain, and a qualified and skilled labour force. Constanta, the only one that resembles with its Chinese counterparts, has been considered because of its capabilities of shipping products right away as they are manufactured. The results would decrease the disparity that exists in revenue levels across Romania, Bucharest leading the group way ahead of the other counties. Foreign direct investments in those areas will attract more others made by the local authorities in the infrastructure (schools, universities, roads, airports, high speed railways. This development will have a direct impact on the current account of the Romania's balance sheet of payments, while

    Full Text Available China's Special Economic Zones (SEZs have been entering a new development stage after China's entry into WTO. China has been developing 'China's economic development model', in which SEZs have ideally been combined with FDIs. China's SEZs concentrated in the east coastal region geographically, specialized in secondary industry, and put in practice many important favourable policies. China's SEZs also play an important role in regional development with the growth pole. At the time of entering the WTO, China's SEZs have been faced with new changes. This paper analyses this new change in China's SEZs, and considers the effect to Korea in the view of policy. In the past ten years, Korea has acquired a better development in the field of economic cooperation. The industrial structure of the two countries has become more and more closed. Especially, the FDI cooperation of the past ten years mostly concentrated on China's SEZs. From the view of country's spatial division, Korea needs to adjust FDI its strategy more diversely in investment regions and industries, and it needs more joint cooperation.

  9. Economic determinants of breastfeeding in Haiti: The effects of poverty, food insecurity, and employment on exclusive breastfeeding in an urban population.

    There is limited and inconsistent empirical evidence regarding the role of economic factors in breastfeeding practices, globally. Studies have found both negative and positive associations between low income and exclusive breastfeeding (EBF). Employment, which should improve household income, may reduce EBF due to separation of mother and infant. In the context of a randomized controlled study of lipid-based complementary feeding in an urban slum in Cap Haitien, Haiti, we examined the economic factors influencing breastfeeding practices using mixed methods. Findings demonstrate relationships between urban context, economic factors, and breastfeeding practices. Poverty, food insecurity, time constraints, and limited social support create challenges for EBF. Maternal employment is associated with lower rates of EBF and less frequent breastfeeding. Extreme food insecurity sometimes leads to increased exclusive breastfeeding among Haitian mothers, what we call "last resort EBF." In this case, women practice EBF because they have no alternative food source for the infant. Suggested policies and programs to address economic constraints and promote EBF in this population include maternal and child allowances, quality child care options, and small-scale household urban food production. © 2017 John Wiley & Sons Ltd.

  10. Graduated Sovereignty and Global Governance Gaps: Special Economic Zones and the Illicit Trade In Tobacco Products.

    Science.gov (United States)

    Holden, Chris

    2017-07-01

    Illicit trade in tobacco products has been a significant problem globally for many years. It allows cigarettes to be sold far below their legal price and thus contributes to higher consumption, morbidity and mortality, and deprives state treasuries of a substantial amount of revenue. This article identifies special economic zones (SEZs), particularly free trade zones, as a key conduit for this illicit trade. The development of SEZs as weak points in the global governance architecture is explained with reference to the concept of 'graduated sovereignty', whereby the uniform management of territory by modern states has given way to a more spatially selective form of territorial governance, in which some slices of territory are more fully integrated into the world economy than others via various forms of differential regulation. Attempts to comprehensively (re)regulate SEZs, in the face of growing evidence of the dysfunctionalities that they can engender, have so far been unsuccessful. It is concluded that the neo-liberal global economy has facilitated a regulatory 'race to the bottom', a problem that can only ultimately be overcome by international negotiation and agreement.

    Endemic non-filarial elephantiasis or podoconiosis is a chronic and debilitating geochemical disease occurring in individuals exposed to red clay soil derived from alkalic volcanic rock. It is a major public health problem in countries in tropical Africa, Central America and North India. To estimate the direct and the average productivity cost attributable to podoconiosis, and to compare the average productivity time of podoconiosis patients with non-patients. Matched comparative cross sectional survey involving 702 study subjects (patients and non-patients) supplemented by interviews with key informants in Wolaita Zone, southern Ethiopia. Total direct costs of podoconiosis amounted to the equivalent of US$ 143 per patient per year. The total productivity loss for a patient amounted to 45% of the total working days per year, causing a monetary loss equivalent to US$ 63. In Wolaita zone, the overall cost of podoconiosis exceeds US$ 16 million per year. Podoconiosis has enormous economic impact in affected areas. Simple preventive measures (such as use of robust footwear) must be promoted by health policy makers.

  18. Exclusion of mRNPs and ribosomal particles from a thin zone beneath the nuclear envelope revealed upon inhibition of transport

    International Nuclear Information System (INIS)

    Kylberg, Karin; Bjoerk, Petra; Fomproix, Nathalie; Ivarsson, Birgitta; Wieslander, Lars; Daneholt, Bertil

    2010-01-01

    We have studied the nucleocytoplasmic transport of a specific messenger RNP (mRNP) particle, named Balbiani ring (BR) granule, and ribosomal RNP (rRNP) particles in the salivary glands of the dipteran Chironomus tentans. The passage of the RNPs through the nuclear pore complex (NPC) was inhibited with the nucleoporin-binding wheat germ agglutinin, and the effects were examined by electron microscopy. BR mRNPs bound to the nuclear basket increased in number, while BR mRNPs translocating through the central channel decreased, suggesting that the initiation of translocation proper had been inhibited. The rRNPs accumulated heavily in nucleoplasm, while no or very few rRNPs were recorded within nuclear baskets. Thus, the transport of rRNPs had been blocked prior to the entry into the baskets. Remarkably, the rRNPs had been excluded both from baskets and the space in between the baskets. We propose that normally basket fibrils move freely and repel RNPs from the exclusion zone unless the particles have affinity for and bind to nucleoporins within the baskets.

  19. The functional state of cellular antioxidant defence system of shoots of Arabidopsis thaliana exposed to the chronic ionizing radiation in the Chornobyl exclusion zone

    The functional state of the cellular antioxidant defence system of shoots of Arabidopsis thaliana plants that grow in natural conditions in the areas of the Chornobyl Exclusion Zone with the values of the external dose rate of 0.45, 0.61, 1.05, 4.81 and 6.80 .Gy/h was evaluated. The decrease of the content of thiobarbituric acid reactive compounds in the shoots of Arabidopsis thaliana was revealed under the external dose rate of 4.81 and 6.80 .Gy/h by 38 and 48 %, respectively, compared to this parameter value under the external dose rate of 0.45 .Gy/h. In the investigated samples the capacity of guaiacol peroxidase increases, catalase and ascorbate peroxidase decreases significantly with the increase of the external dose rate from 0.45 to 6.80 .Gy/h. Probably, revealed changes in the functional state of the cellular antioxidant defence system of the shoots of Arabidopsis thaliana in the conditions of radioactive contamination are adaptive in nature.

  20. METHOD FOR SIMULTANEOUS 90SR AND 137CS IN-VIVO MEASUREMENTS OF SMALL ANIMALS AND OTHER ENVIRONMENTAL MEDIA DEVELOPED FOR THE CONDITIONS OF THE CHERNOBYL EXCLUSION ZONE

    Energy Technology Data Exchange (ETDEWEB)

    Farfan, E.; Jannik, T.

    2011-10-01

    To perform in vivo simultaneous measurements of the {sup 90}Sr and {sup 137}Cs content in the bodies of animals living in the Chernobyl Exclusion Zone (ChEZ), an appropriate method and equipment were developed and installed in a mobile gamma beta spectrometry laboratory. This technique was designed for animals of relatively small sizes (up to 50 g). The {sup 90}Sr content is measured by a beta spectrometer with a 0.1 mm thick scintillation plastic detector. The spectrum processing takes into account the fact that the measured object is 'thick-layered' and contains a comparable quantity of {sup 137}Cs, which is a characteristic condition of the ChEZ. The {sup 137}Cs content is measured by a NaI scintillation detector that is part of the combined gamma beta spectrometry system. For environmental research performed in the ChEZ, the advantages of this method and equipment (rapid measurements, capability to measure live animals directly in their habitat, and the capability of simultaneous {sup 90}Sr and {sup 137}Cs measurements) far outweigh the existing limitations (considerations must be made for background radiation and the animal size, skeletal shape and body mass). The accuracy of these in vivo measurements is shown to be consistent with standard spectrometric and radiochemical methods. Apart from the in vivo measurements, the proposed methodology, after a very simple upgrade that is also described in the article, works even more accurately with samples of other media, such as soil and plants.

    To predict parameters of radionuclide resuspension, transport and deposition during forest and grassland fires, several model modules were developed and adapted. Experimental data of controlled burning of prepared experimental plots in the Chernobyl exclusion zone have been used to evaluate the prognostic power of the models. The predicted trajectories and elevations of the plume match with those visually observed during the fire experiments in the grassland and forest sites. Experimentally determined parameters could be successfully used for the calculation of the initial plume parameters which provide the tools for the description of various fire scenarios and enable prognostic calculations. In summary, the model predicts a release of some per mille from the radionuclide inventory of the fuel material by the grassland fires. During the forest fire, up to 4% of 137 Cs and 9 Sr and up to 1% of the Pu isotopes can be released from the forest litter according to the model calculations. However, these results depend on the parameters of the fire events. In general, the modeling results are in good accordance with the experimental data. Therefore, the considered models were successfully validated and can be recommended for the assessment of the resuspension and redistribution of radionuclides during grassland and forest fires in contaminated territories

    We study the performance of the euro-Swiss franc exchange rate in the extraordinary period from September 6, 2011 to January 15, 2015 when the Swiss National Bank enforced a minimum exchange rate of 1.20 Swiss francs per euro. Within the general framework built on geometric Brownian motions and based on the analogy between Brownian motion in finance and physics, the first-order effect of such a steric constraint would enter a priori in the form of a repulsive entropic force associated with the paths crossing the barrier that are forbidden. Nonparametric empirical estimates of drift and volatility show that the predicted first-order analogy between economics and physics is incorrect. The clue is to realize that the random-walk nature of financial prices results from the continuous anticipation of traders about future opportunities, whose aggregate actions translate into an approximate efficient market with almost no arbitrage opportunities. With the Swiss National Bank's stated commitment to enforce the barrier, traders' anticipation of this action leads to a vanishing drift together with a volatility of the exchange rate that depends on the distance to the barrier. This effect is described by Krugman's model [P. R. Krugman, Target zones and exchange rate dynamics, Q. J. Econ. 106, 669 (1991)]. We present direct quantitative empirical evidence that Krugman's theoretical model provides an accurate description of the euro-Swiss franc target zone. Motivated by the insights from the economic model, we revise the initial economics-physics analogy and show that, within the context of hindered diffusion, the two systems can be described with the same mathematics after all. Using a recently proposed extended analogy in terms of a colloidal Brownian particle embedded in a fluid of molecules associated with the underlying order book, we derive that, close to the restricting boundary, the dynamics of both systems is described by a stochastic differential equation with a very

    This paper aims to evaluate the potential of renewable energy sources of solar and wind in three free economic and industrial zones of Chabahar, Kish and Salafchegan in Iran. Feasibility of harnessing solar energy was investigated by using key solar parameters like monthly mean global, beam and diffuse solar radiation as well as clearness index. It was found that all locations had great potentials for utilizing different solar energy systems. Additionally, the monthly, seasonal, semi-yearly and yearly optimum tilt angles of south-facing solar surfaces were determined. For all zones, adjusting the tilt angle twice a year or in other words, the semi-yearly tilt adjustment for two periods of warm (April–September) and cold (October–March) were highly recommended, since it offers almost the same level of annual solar energy gain (SEG) as those of monthly and seasonal adjustments. Weibull Distribution Function (WDF) was performed for analyzing the wind potentials at different heights. It was found that Chabahar was not suitable for wind energy development, but Kish and Salafchegan with yearly wind powers of 111.28 W/m 2 and 114.34 W/m 2 , respectively ranked in class 2 which are considered marginal for wind power development. Three different wind turbine models were proposed for Kish and Salafchegan. - Highlights: • Feasibility of solar and wind energy for three locations of Iran was investigated. • All locations were suitable for solar energy utilization. • The optimum tilt angles of solar surfaces were determined. • Chabahar was unsuitable, but Kish and Salafchegan were marginal for wind purpose

    Full Text Available In 2014 the South African government formally sanctioned the establishment of Special Economic Zones (SEZs in that country. The importance attached to SEZs reflects a clear return to spatially-based economic interventions following the recognition of the persistence of deep-rooted structural and spatial inequalities in the country. This paper discusses South Africa’s past and present involvement in processes of spatial economic development and how the SEZ concept has emerged. The potential of SEZs is assessed relative to local experience with the lack-lustre performance of what were termed Industrial Development Zones (IDZs since 2001. While re-engagement with issues of how to address ‘uneven geographical development’ is clearly significant, it would be difficult to argue that SEZs will achieve guaranteed success.

    The Pearl River Delta Economic Zone is one of the most developed regions in China. It has been undergoing a rapid urbanization since the reformation and opening of China in 1978. This process plays a significant impact on the urban environment, particularly river water quality. The main goal of this present study is to assess the impact of urban activities especially urbanization on river water quality for the study area. Some Landsat TM images from 2000 were used to map the areas for different pollution levels of urban river sections for the study area. In addition, an improved equalized synthetic pollution index method was utilized to assess the field analytical results. The results indicate that there is a positive correlation between the rapidity of urbanization and the pollution levels of urban river water. Compared to the rural river water, urban river water was polluted more seriously. During the urban development process, urbanization and urban activities had a significant negative impact on the river water quality.

    China's coastal zone plays an important role in ecological services production and social-economic development; however, extensive and intensive land resource utilization and land use change have lead to high ecological risk in this area during last decade. Regional ecological risk assessment can provide fundamental knowledge and scientific basis for better understanding of the relationship between regional landscape ecosystem and human activities or climate changes, facilitating the optimization strategy of land use structure and improving the ecological risk prevention capability. In this paper, the Yellow River Delta High-Efficiency Ecological Economic Zone is selected as the study site, which is undergoing a new round of coastal zone exploitation and has endured substantial land use change in the past decade. Land use maps of 2000, 2005 and 2010 were generated based on Landsat images by visual interpretation method, and the ecological risk index was then calculated. The index was 0.3314, 0.3461 and 0.3176 in 2000, 2005 and 2010 respectively, which showed a positive transition of regional ecological risk in 2005

    The nuclear power plants accidents of Chernobyl and Fukushima demonstrate the importance of the understanding of the transfer of the radioactive contamination in the environment and its ecological consequences. Although certain studies have been realized on superior organisms of the food chain, studies on telluric bacterial communities are scarce. The latter play nevertheless an essential role in the mobility of contaminants in soils by decreasing or improving their transfer towards other compartments (water, vegetables and animals). Moreover radionuclides (RNs) can have toxic effects on bacteria, leading to an inhibition of their participation in such transfer. The objectives of this study were (1) to estimate the impact of the radioactive contamination on bacterial communities belonging to a soil of the Chernobyl exclusion zone (trench T22) and (2) to study the uranium-bacteria interactions of a resistant strain, isolated from this soil. The various techniques used to characterize the bacterial diversity (culture of bacteria, DGGE, 454 pyro-sequencing) all testified of the multiplicity and the abundance of the bacterial communities in spite of the contamination. An impact on the community structure was difficult to assess by DGGE or cultural approach, but was nevertheless highlighted by the use of pyro-sequencing, suggesting the presence of species more adapted to the contaminated soil conditions. A specific molecular tool dedicated to the search of bacteria affiliated to the known radiation resistant Deinococcus-Thermus phylum (for example the Deinococcus radiodurans specie survives after an irradiation of several kGy) was developed. However it did not reveal the presence of bacteria affiliated to such a phylum in the studied soil. In parallel to the study of the bacterial biodiversity, about fifty culturable bacteria were isolated from this site and were used as a support to select a species (Microbacterium) capable to survive strong U(VI) concentrations.

    The Pars Special Economic Energy Zone (PSEEZ) is located in the south of Iran, on the northern coastline of the Persian Gulf. This area was established in 1998 for the utilization of south Pars field oil and gas resources. This field is one of the largest gas resources in the world and contains about 6% of the total fossil fuels known. Petrochemical industries, gas refineries and downstream industries are being constructed in this area. At present there are three gas refineries in operation and five more gas refineries are under construction. In this study, different types of solid waste including municipal solid waste (MSW) and industrial wastes were investigated separately. The aim of the study was to focus on the management of the industrial wastes in order to minimize the environmental impact. In the first stage, the types and amounts of industrial waste in PSEEZ were evaluated by an inventory. The main types of industrial waste are oil products (fuel oil, light oil, lubricating oil), spent catalysts, adsorbents, resins, coke, wax and packaging materials. The waste management of PSEEZ is quite complex because of the different types of industry and the diversity of industrial residues. In some cases recycling/reuse of waste is the best option, but treatment and disposal are also necessary tools. Recently a design has been prepared for a disposal site in PSEEZ for the industrial waste that cannot be reused or recycled. The total surface area of this disposal site where the industrial waste should be tipped for the next 20 years was estimated to be about 42 000 m2.

    Full Text Available The aim of this study was to determine the energy consumption and economic analysis for strawberry production. The data were collected from 60 farmers growing strawberry in the Sanandaj zone of Iran by using a face-to-face questionnaire in August-September 2009. The plowing operation at the study area was done by two methods; manually plow (P1 and machinery plow (P2. Also the irrigation operation was done by two methods; pumping irrigation (P and non pumping irrigation (NP. Univariate analysis of variance was used for finding the differences among the total energy used for production and profitability of this crop in the different methods at the 5% and 1% level. Total energy used in various farm operations during strawberry production was 53,605 MJ.ha-1. Total energy output was 17,338 MJ.ha-1, and the average annual yield of strawberry farms was 9,125 kg.ha-1. Energy efficiency was 0.32, and energy productivity calculated as 0.17 kg.MJ-1. This means a production of 0.17 kg per unit energy. The difference between total input energy in the different irrigation types (NP and P is significant at 1% level. There is not any significant difference between different plow types at the 5% level. The interaction of irrigation types and plow types is significant at 5% level. The profit-cost ratio, productivity, and net profit in the strawberry production are 1.2, 0.99, and 1,825 $.ha-1, respectively. The difference between net return in the different irrigation types (NP and P is significant at 5% level. The difference between net return in the different plow types (P1 and P2 is significant at 1% level.

    Land use/land cover change has been attracting increasing attention in the field of global environmental change research because of its role in the social and ecological environment. To explore the ecological risk characteristics of land use change in the Poyang Lake Eco-economic Zone of China, an eco-risk index was established in this study by the combination of a landscape disturbance index with a landscape fragmentation index. Spatial distribution and gradient difference of land use eco-risk are analyzed by using the methods of spatial autocorrelation and semivariance. Results show that ecological risk in the study area has a positive correlation, and there is a decreasing trend with the increase of grain size both in 1995 and 2005. Because the area of high eco-risk value increased from 1995 to 2005, eco-environment quality declined slightly in the study area. There are distinct spatial changes in the concentrated areas with high land use eco-risk values from 1995 to 2005. The step length of spatial separation of land use eco-risk is comparatively long—58 km in 1995 and 11 km in 2005—respectively. There are still nonstructural factors affecting the quality of the regional ecological environment at some small-scales. Our research results can provide some useful information for land eco-management, eco-environmental harnessing and restoration. In the future, some measures should be put forward in the regions with high eco-risk value, which include strengthening land use management, avoiding unreasonable types of land use and reducing the degree of fragmentation and separation.

    Radiation situation within the Chernobyl Exclusion Zone (ChEZ) is determined by high radionuclides contamination of the land surface formed after the 1986 accident, as well as the presence of a number of potentially hazardous objects (the 'Shelter' object, the Interim Spent Nuclear Fuel Dry Storage Facility ISF-1, radioactive waste disposal sites, radioactive waste temporary localization sites etc.). The air concentration of radionuclides over the ChEZ territory and radiation exposure of personnel are influenced by natural and anthropogenic factors: variable weather conditions, forest fires, construction and excavation activity etc. The comprehensive radiation monitoring and early warning system in the ChEZ was established under financial support of European Commission in 2011. It involves the computer system developed for assessment and prediction of radiological emergencies consequences in the ChEZ ensuring the protection of personnel and the population living near its borders. The system assesses radiation situation under both normal conditions in the ChEZ and radiological emergencies which result in considerable radionuclides emission into the air (accidents at radiation hazardous objects, extreme weather conditions). Three different types of radionuclides release sources can be considered in the software package. So it is based on a set of different models of emission, atmospheric transport and deposition of radionuclides: 1) mesoscale model of radionuclide atmospheric transport LEDI for calculations of the radionuclides emission from stacks and buildings; 2) model of atmospheric transport and deposition of radionuclides due to anthropogenic resuspension from contaminated area (area surface source model) as a result of construction and excavation activity, heavy traffic etc.; 3) model of resuspension, atmospheric transport and deposition of radionuclides during grassland and forest fires in the ChEZ. The system calculates the volume and surface

    The Philippine Nuclear Research Institute (PNRI) measured radiation levels at the Clark Special Economic Zone (CSEZ) using a carbon gamma-ray spectrometric system (Exploration Gr-650) equipped with a Nal detector and global positioning system in 1998. The measurement covered approximately 131 km of CSEZ road network and generated 6875 data. Soil and water samples within the specified area were also collected for specific radionuclide activity analyses using high pressure germanium (HPGe) detector. The Health Physics Research Section (HPRS) of the PNRI has earlier established the average baseline level of absorbed dose rate received by the Filipino population due to primordial (naturally-occurring) radionuclides ( 238 U, 232 Th and 40 K) at 45 nGy h -1 (n = 1645 locations) with ranges from 5 to 74 nGy h-1. The estimated average absorbed dose rate in 23 countries by the United National Scientific Committee on the Effect of Atomic Radiation (UNSCEAR, 1982) was reported at 55 nGy h -1 . The average absorbed dose rate in air measured within CSEZ is 26.3 ± 6.68 nGy h -1 with ranges from 13.27 to 37.93 nGy h-1 . This average value is within the range of values observed in other parts of the country outside of CSEZ and hence can be attributed to natural source of radiation, not man-made sources. To confirm the above measurements, the contribution of man-made sources to the total dose rate measured was assessed further. Evaluation of natural and man-made sources of radiations is achieved through count rate ratio measurements of low energy, 35-350keV, (natural radiation) and high energy, 350-2800 keV, (anthropogenic radiation) spectra of gamma radiation. The ratios of low to high energy remained practically constant throughout the entire area monitored. Initial analyses of soil and water samples collected in areas of interest within the CSEZ for specific radionuclides using the HPGe detector indicated activity concentrations within baseline levels of these radionuclides

    The results of studies of radioactive contamination of ichthyofauna of water bodies of the Chernobyl exclusion zone (ChEZ) during 2012-2013 are presented. The fish sampled from water bodies with different hydrological mode was used: (1) stagnant lakes (Vershyna, Glyboke, Azbuchyn, Daleke); (2) reservoir with slow water exchange (cooling pond of the Chernobyl NPP); (3) conditionally stagnant water bodies (separated from the main riverbed of the Pripyat River - Yanovsky and Novoshepelichesky Crawls and part of the Krasnensky former river bed); (4) semi-flowing water body (Krasnensky former river bed located outside of the dammed territory); (5) open crawls of the Pripyat river ('Schepochka' and Chernobylsky) and (6) waterway (riverbed sites of the Pripyat River). The highest levels of radionuclide concentrations were determined in fish of the stagnant water objects - 937-25907 Bq/kg (w.w.) of {sup 137}Cs and 1845-101220 Bq/kg of {sup 90}Sr. In fish of cooling pond the concentration of {sup 137}Cs registered in range 750-4200 and {sup 90}Sr - 41-512 Bq/kg. In ichthyofauna of water bodies which concern to the third group, specific activity of {sup 137}Cs and {sup 90}Sr fluctuated accordingly within range of 520-3385 and 722-6210, and in a semi-flowing reservoir - 573-2948 and 97-4484 Bq/kg. The concentrations of {sup 137}Cs in fish of the fifth and sixth groups were accordingly 25-159 and 11-224 as well as {sup 90}Sr - 36-174 and 3-14 Bq/kg. The ratio of specific activity of {sup 90}Sr/{sup 137}Cs for pray fish from all studied groups of water bodies, except the second and the sixth ones, was in range 1.5-39.7. Thus intensity of water exchange is one of the defining factors, influencing on level of radionuclide specific activity in fish, especially {sup 90}Sr - the higher the flow age, the lower the level of radioactive contamination of fish inhabiting it. Calculation of the absorbed dose rate has shown that highest radiation dose was in fish inhabiting lake

    Full Text Available While State and local governments have long turned to legal norms, such as vagrancy ordinances and anti-panhandling by-laws, and relied on displacement strategies ranging from orders to disperse and forced removals to control disorderly behavior in public spaces, the ways in which courts and legal actors working within the criminal justice system contribute to the monitoring of public spaces have almost completely gone unnoticed. This paper focuses on one court-imposed spatial tactic, namely zone restriction or "no go" orders. We suggest that despite the fact that these court orders rely on preventative discourses and pursue rehabilitative objectives, they may ultimately have punitive effects on the public poor and political demonstrators and contribute to creating and reproducing socio-economic inequality by creating obstacles for their reintegration, encouraging recidivism, putting the safety of individuals at risk and by neutralizing those who challenge the social and political order in various ways. Ultimately, these orders raise some concerns with respect to the rule of law since they are rarely challenged and generally appear to be shielded from review. Mientras que estados y gobiernos locales han vuelto a normas legales como la ley de vagos y maleantes, y basan sus estrategias en el desplazamiento, mediante órdenes de dispersión y traslados forzosos para controlar el comportamiento desordenado en los espacios públicos, ha pasado prácticamente desapercibida la forma en la que tribunales y agentes jurídicos trabajan dentro del sistema de justicia penal para contribuir a la vigilancia de los espacios públicos. Este artículo se centra en una táctica espacial impuesta por un tribunal, concretamente la restricción de zona o pedidos "intangibles". Se sugiere que, a pesar de que estas órdenes judiciales se basan en discursos preventivos y persiguen objetivos de rehabilitación, en última instancia pueden tener efectos punitivos sobre

    Full Text Available In spite of the complexity in defining the boundary, the concept of Economic Zones (EZ has been evolved as a way forward for the government of the developing countries for enhancing the national trade. Similarly the recent phenomenon of widespread Public Private Partnership (PPP practices especially in infrastructure sector is also providing a window to develop many of such economic zones through PPP model as EZ typically is capital intensive. Bangladesh has discrete success both under PPP and EZ regime. However, developing EZ under PPP model has few commercial complexities as both the public and private sector need to bear some roles and obligations one of which is selection of appropriate location for EZ development. The location study for PPP EZ development therefore receives paramount attention both from developer and lenders perspective. Such location study generally is not typical project site study by nature; rather it is more economic concentrated. This paper will try to identify the factors that are essential to consider for conducting these location studies based on the examples of Bangladesh. The paper will also identify the appropriate methods and approaches required for successful EZ development through PPP.

    Full Text Available In this paper, we take the establishment of Poyang Lake Eco-Economic Zone in 2009 as a quasi-natural experiment, to evaluate its influence on the agricultural labor productivity in Jiangxi Province, China. The estimation results of the DID method show that the establishment of the zone reduced agricultural labor productivity by 3.1%, lowering farmers’ net income by 2.5% and reducing the agricultural GDP by 3.6%. Furthermore, this negative effect has increased year after year since 2009. However, the heterogeneity analysis implies that the agricultural labor productivities of all cities in Jiangxi Province will ultimately converge. We find that the lack of agricultural R&D activities and the abuse of chemical fertilizers may be the main reasons behind the negative influence of the policy, by examining two possible transmission channels—the R&D investment and technological substitution. Corresponding policy implications are also provided.

    Water-soluble, exchangeable and acid-soluble (IM HCI) forms of {sup 90} Sr and {sup 137} Cs were determined in 15 layer-by-layer (1 cm) samples of podzolis and peaty soils from the Chernobyl exclusion zone taken in 1991 and 1992. Positions of centers of {sup 137} Cs and {sup 90} Sr supply as well as their water-soluble and exchangeable forms were estimated. The data obtained testify to deceleration of vertical migration of {sup 137} Cs in soils till the early 90th. The conclusion is made on evolution of dominating mechanisms of vertical migration of radionuclides. It consists in a decrease of the lessivage significance.

For this purpose, the following research methods were used: literature research, intuitive method and descriptive statistics. Poland has fulfilled the criteria for nominal convergence for two years, apart from participating in the ERM II mechanism, but the political situation in the country precludes the adoption of measures leading to the euro zone. The future shape of this zone is yet unknown, as its closer integration is planned. Theoretical analysis indicates that the process of globalization makes it difficult for medium-sized, open-economy countries to pursue autonomous monetary and exchange rate policy, so the loss of these instruments after the adoption of the euro should not jeopardize long-term economic growth, even in the case of asymmetric shocks. The market mechanisms of restoring the balance and fiscal policy may then be used. The economy will also benefit from the elimination of transaction costs and exchange rate risks in the euro zone. The analysis shows that it is possible to use the opportunity for faster GDP growth associated with the adoption of the common currency if the right economic policy is pursued. Adopting the euro may also incur costs. For banks it can be the loss of foreign exchange earnings and commissions on FX hedge transactions. For the economy it can be the possibility of speculative bubbles, as a result of excessive consumption growth, caused by possibly too low interest rates. Expected benefits should, however, outweigh any losses.

    Today, one of the most grave environmental health problems being faced by the urban population is the poor air quality one breathes in. To testify the above statement, the recent survey report, World health statistics (WHO, 2012) reflects the fact that childhood mortality ratio from acute respiratory infection is one of the top leading causes of death in developing countries like India. Urban areas have a complex social stratification which ultimately results in forming different urban economic zones. This research attempts to understand the Indoor Air Quality (IAQ) by taking into consideration different lifestyle of occupants inhabiting these economic zones. The Study tries to evaluate the outdoor and indoor air quality by understanding the variation of selected pollutants (SPM, SOx, NOx) for the duration of four months - from October, 2012-January, 2013. For this, three economic zones (EZ) of Delhi University’s North Campus, were selected - Urban Slum (EZ I), Clerical (EZ II) and Faculty residence (EZ III). The statistical study indicates that Urban Slum (EZ I) was the most polluted site reporting maximum concentration of outdoor pollutants, whereas no significant difference in pollution load was observed in EZ II and EZ III. Further, the indoor air quality was evaluated by quantifying the indoor and outdoor pollution concentration ratios that shows EZ III have most inferior indoor air quality, followed by EZ I and EZ II. Moreover, it was also observed that ratio (phenomenon of infiltration) was dominant at the EZ II but was low for the EZ I and EZ III. With the evidence of high Indoor air pollution, the risk of pulmonary diseases and respiratory infections also increases, calling for an urgent requisite for making reforms to improve IAQ. Key words: Urban Area, Slum, IAQ, SOx, NOx, SPM

    2017-02-01

    Full Text Available A model for managing the balance of pollution (getting into the sea with the coastal runoff assimilation and accumulation, based on the negative feedback between the coastal economic system efficiency and penalties for the sea coastal zone pollution is proposed. The model is constructed by the Adaptive Balance of Causes method and is intended for finding a rational balance of profit from the use of assimilative resources of the marine environment and the costs of maintaining its quality. The increase of pollutions in the coastal zone is taken as proportional to the volume of product realization. The decrease of pollution concentration is related to the environment protection activities paid for by the production. The model contains the agents for managing the volume of the economic system generalized production release. The agents control pollution accumulation rate at different ones of the bio-chemical processes resulting in the marine environment natural purification. Scenario analysis of ecological-economic processes in the “Land–Sea” system is carried out, and the dependencies of economic subsystem production profitability on penalty sanctions limiting the pollutant flux getting into the sea are constructed. Sea temperature and water mass dynamics effect on these processes is considered. The scenarios of their intra-annual variability are constructed. It is shown that the sea temperature and near-water wind consideration in the model have a significant effect on marine environment pollution level and production profitability. The conclusion is that the proposed adaptive simulation model “Sea–Land” can be used for forecasting the scenarios of coastal subsystem production processes (the volume of generalized product manufacturing, production cost, profitability in parallel with the forecast of pollution concentration in the sea scenarios.

    2014-01-01

    This study was designed to compare costs of rearing and returns received from major dairy buffalo breeds (Nili-Ravi and Kundhi) in various agro-ecological zones of Pakistan. For this purpose, 219 buffalo farmers were randomly selected from mixed and rice-wheat cropping zones of Punjab and Sindh provinces, mixed cropping zone of Khyber Pakhtunkhwa (KPK) province, coastal zone of Sindh and mountainous-AJK. Of these, 155 and 64 were Nili-Ravi and Kundhi buffalo breed farmers, respectively. The study revealed that among the structure of cost components, feed cost occupied the major share in total cost of milk production. Milk production of buffaloes of Nili-Ravi and Kundhi breeds were 2889 and 2375 liter per annum, respectively. Total costs of milk production of Nili-Ravi and Kundhi buffalo breeds were Rs.96155 and Rs.90604 per annum, respectively. Net income per liter from milk of Nili-Ravi and Kundhi breeds was Rs.12 and Rs.11, and benefit-cost ratios were 1.4 and 1.3, respectively. Hence, Nili-Ravi buffalo breed is more productive and yields better returns over Kundhi breed. Moreover, buffalo milk production is a profitable business in the country except in coastal areas of Sindh, where investment in milk production just covers the cost of production due to comparatively higher feed prices and low milk prices. Econometric analysis of milk production in the country revealed that use of green fodder and concentrates contribute positively and significantly to milk production. (author)

    2004-01-01

    Full Text Available The Carter-Torrijos Treaty of 1978, the initiative to relinquish controi of the Panama Canal Zone to the Republic of Panama, allowed Panama for the first time in its short history to become an autonomous nation and to take control of its destiny as a global trading crossroads. Conservatives rallied against President Carter and accused him of jeopardizing U. S. security and hegemony. Fears were that Panama did not have the economic or technical resources to maintain Canal operations, lacked the administrative knowledge and resources to manage the business of the Canal, lacked the military presence to insure security of the Canal, and did not have the political and social will to maintain the environmental integrity of the region. In short, disastrous results were predicted. Carter prevailed. December 31, 1999 saw the surrender of the Canal Zone, and all its facilities, to Panama. This paper discusses events that precipitated Carter’s decision, economic and political arguments presented during the 1977-78 debate, implementation of the treaty, and an evaluation of the ‘business of the Canal’ today.

    This study investigates the thermal energy potentials and economic feasibility of an air-conditioned family household-integrated phase change material (PCM) considering different climate zones in Morocco. A simulation-based optimisation was carried out in order to define the optimal design of a PCM-enhanced household envelope for thermal energy effectiveness and cost-effectiveness of predefined candidate solutions. The optimisation methodology is based on coupling Energyplus® as a dynamic simulation tool and GenOpt® as an optimisation tool. Considering the obtained optimum design strategies, a thermal energy and economic analysis are carried out to investigate PCMs' integration feasibility in the Moroccan constructions. The results show that the PCM-integrated household envelope allows minimising the cooling/heating thermal energy demand vs. a reference household without PCM. While for the cost-effectiveness optimisation, it has been deduced that the economic feasibility is stilling insufficient under the actual PCM market conditions. The optimal design parameters results are also analysed.

    2017-03-01

    While the development of the tourism industry can bring economic benefits to an area, it is important to consider the long-run impact of the industry on a given location. Particularly when the tourism industry relies upon a certain ecological state, those weighing different development options need to consider the long-run impacts of increased tourist numbers upon measures of ecological condition. This paper presents one approach for linking a model of recreational visitor behavior with an ecological model that estimates the impact of the increased visitors upon the environment. Two simulations were run for the model using initial parameters available from survey data and water quality data for beach locations in Croatia. Results suggest that the resilience of a given tourist location to the changes brought by increasing tourism numbers is important in determining its long-run sustainability. Further work should investigate additional model components, including the tourism industry, refinement of the relationships assumed by the model, and application of the proposed model in additional areas.

  15. Assessment of environmental change and its socio-economic impacts in the mangrove ecological zone of the Niger Delta, Nigeria

    Science.gov (United States)

    James, Godstime Kadiri

    The Niger Delta, located in the central part of Southern Nigeria, is endowed with immense Mangrove resources, estimated to be the fourth largest in the world. The term Mangrove refers to salt tolerant species of trees or shrubs that grow on shores and in estuaries located in the coastal tropics and sub-tropical regions of the world. They support highly productive marine food chains. However, Mangrove ecosystems are in serious decline around the world due to the rapid increase in maritime commerce and exploration of mineral resources in the last few decades. These pressures often have immediate consequences on sensitive coastal environments and can potentially impact future human use of coastal space and resources. This dynamic process presents unique opportunities for research to explore the nature and consequences of these pressures. This dissertation focused on the Mangrove ecological zone of the Niger Delta, where resource exploitation and indigenous use of the environment are in direct conflict with important socio-economic implications. Environmental accounting metrics derived from the Driver-Pressure-State-Impact-Response (DPSIR) framework were used to assess changes in the spatial extent of the Niger Delta Mangrove ecosystem and the socio-economic impacts of the observed changes. Landsat remotely sensed satellite data from the mid-1980s through 2003 was used to assess change in the spatial extent of the Mangrove vegetation in the region. A total of 21,340 hectares of Mangrove forest was determined to be lost over the study period. Field research in the region confirmed that this loss was primarily driven by urbanization and activities of the multinational oil and gas corporations operating in the region. To estimate the socio-economic impacts of the Mangrove loss in the region, neoclassical economic valuation and participatory social valuation approaches were adopted. Results from the economic valuation revealed that the net present value of future income

    The distribution of cesium and strontium as well as their chemical analogs potassium and calcium in the biomass of aquatic plants collected in zone of radioactive contamination of the Yenisei River and in Glubokoe Lake, in Chernobyl accident exclusion zone, was investigated with chemical fractionation technique. Despite of the essential difference in activity concentration in the biomass of the plants from the two water bodies, the distribution of 137 Cs among the biomass fractions was similar. 90 Sr was recorded in the biomass in more mobile form, than 137 Cs. The distribution of cesium in the biomass of plants essentially differed from the distribution of it's chemical analog, potassium. The distribution of elements - analogs, 90 S and Ca, in the biomass of the plants was similar. More than half of cesium concentration in the samples of plants from the Yenisei River was associated with particles of seston, bound to the surface of the plants. The results obtained should be considered while interpret the data of radioecological monitoring and modeling of the migration of radionuclides in the water bodies.

    The objective of the economic dispatch problem (EDP) of electric power generation, whose characteristics are complex and highly nonlinear, is to schedule the committed generating unit outputs so as to meet the required load demand at minimum operating cost while satisfying all unit and system equality and inequality constraints. Recently, as an alternative to the conventional mathematical approaches, modern meta-heuristic optimization techniques have been given much attention by many researchers due to their ability to find an almost global optimal solution in EDPs. Research on merging evolutionary computation and quantum computation has been started since late 1990. Inspired on the quantum computation, this paper presented an improved quantum-inspired evolutionary algorithm (IQEA) based on diversity information of population. A classical quantum-inspired evolutionary algorithm (QEA) and the IQEA were implemented and validated for a benchmark of EDP with 15 thermal generators with prohibited operating zones. From the results for the benchmark problem, it is observed that the proposed IQEA approach provides promising results when compared to various methods available in the literature.

    Full Text Available The aim of this paper is to present the spatial distribution of openness to foreign trade assessed at the local level (LAU 1, poviats in Poland, between 2005 and 2012, with particular reference to its two determinants: activity of foreign-owned enterprises (FOEs and functioning of special economic zones (SEZs. With the use of data from different sources, including the foreign trade statistics for the Polish regions, constituting a set of indicators on openness to foreign trade, we deliberate on the determinants and the character of regional openness, as well as the quality of the proxies used in order to assess their spatial distribution. Our results indicate high regional dissimilarities in terms of export activity, correlated with the broader picture of regional inequalities. The role of FOEs has been crucial in determining the spatial distribution of exports. As regards the SEZs, their sole contribution increased significantly during the time span. In the times of the world financial crisis, the export performance diversity of poviats increased temporarily but diminished afterwards.

    The assessment of the fluctuating asymmetry based on measurement of the parameters of left and right parts of silver birch (Betula pendula (L.) Roth.) leaves and relative sizes of pairs of Scots pine (Pinus sylvestris L.) needles from the Chernobyl Exclusion Zone (ChEZ) was carried out. Twelve samples of both birch leaves and pairs of needles were collected from 10 trees at 5 sites in the Chernobyl Exclusion Zone and also at one control site located outside the ChEZ. Values of gamma dose rate in the air varied between the sites from 0.1 to 40 μGy h -1 . Activity concentrations of 90 Sr and 137 Cs in the birch leaves varied over the range of 0.9÷2460 kBq kg -1 and 0.1÷339 kBq·kg -1 (DW), respectively. In addition to the above, in the Scots pine needles, these ranges were 0.7 ÷1970 kBq kg -1 f for 90 Sr and 0.1÷78 kBq kg -1 (DW) for 137 Cs. From the values of the radionuclides activity concentrations in the plants, the internal dose rate is estimated to be in the range of 0.1 ÷ 274 μGy h -1 . The main sources of the internal dose rate were radiation of 90 Sr and 90 Y. Indices of fluctuating asymmetry of silver birch leaves and Scots pine needles varied over the range of 0.048 ± 0.007 ÷ 0.060 ± 0.009 and 0.014 ± 0.002 ÷ 0.018 ± 0.002, respectively, and did not statistically differ for all experimental sites. The indices also did not depend on the external or internal dose rate of ionizing radiation for plants. The above findings seem to be consistent with other research effort in terms of understanding the response of organisms to chronic pollutant exposure and the long-term effects of large scale nuclear accidents.

A technique developed previously was used in an attempt to classify the pegmatites as containing economically significant quantities of these rare elements or as barren. Twenty-one of the samples were collected from pegmatites that were known (from previous attempts to mine them) to be either economically significant or barren, and were used as a control group; 75 per cent of these samples were classified correctly. Of twenty samples from pegmatites of unknown economic potential, two were classified as economically significant. However, in view of the low rate of success of classification of the control group, it is considered that further refinement of the technique is necessary before classification of a pegmatite as containing economically significant amounts of minerals can be considered to be conclusive

    The hypothesis is proposed that pre-biotic bacterial cell(s) and the first cells capable of growth/division did not require a cytoplasmic membrane. A gel-like microscopic structure less than a cubic micrometer may have had a dual role as both an ancient pre-cytoplasm and a boundary layer to the higher-entropy external environment. The gel pre-cytoplasm exposed to radiant energy, especially in the infrared (IR) region of the EM spectrum resulted in the production of an exclusion zone (EZ) with a charge differential (-100 to -200 mV) and boundary that may have been a possible location for the latter organization of the first cytoplasmic membrane. Pre-biotic cells and then-living cells may have used hydrogen as the universal energy source, and thermosynthesis in their bioenergetic processes. These components will be discussed as to how they are interconnected, and their hypothesized roles in the origin of life. Copyright © 2011 Elsevier Masson SAS. All rights reserved.

    Millward, Andrew Allan

    Throughout most of China, and particularly in the coastal areas of its south, ecological resources and traditional culture are viewed by many to be negatively impacted by accelerating urbanization. As a result, achieving an appropriate balance between development and environmental protection has become a significant problem facing policy-makers in these urbanizing areas. The establishment of a Special Economic Zone in the Chinese Province of Hainan has made its coastal areas attractive locations for business and commerce. Development activities that support a burgeoning tourism industry, but which are damaging the environment, are now prominent components of the landscape in the Sanya Region of Hainan. In this study, patterns of urban growth in the Sanya Region of Hainan Province are investigated. Specifically, using several forms of satellite imagery, statistical tools and ancillary data, urban morphology and changes to the extent and spatial arrangement of urban features are researched and documented. A twelve-year chronology of data was collected which consists of four dates of satellite imagery (1987, 1991, 1997, 1999) acquired by three different satellite sensors (SPOT 2 HRV, Landsat 5 TM, Landsat 7 ETM+). A method of assessing inter-temporal variance in unchanged features is developed as a surrogate for traditional evaluations of change detection that require spatially accurate and time-specific data. Results reveal that selective PCA using visible bands with the exclusion of an ocean mask yield the most interpretable components representative of landscape urbanization in the Sanya Region. The geostatistical approach of variography is employed to measure spatial dependence and to test for the presence of directional change in urban morphology across a time series of satellite images. Interpreted time-series geostatistics identify and quantify landscape structure, and changes to structure, and provide a valuable quantitative description of landscape change

    Nursing and teaching are considered risk professions with high levels of stress and burnout. Dual-qualification nursing teachers (DQNT) are nurses who both teach and practise. These nurses face additional stress. This study explored the stressors of DQNT in the Chengdu-Chongqing Economic Zone of China. This qualitative study used in-depth, open-ended interviews. The interview responses were analysed using a grounded theory approach. The participants in this study included 21 DQNT from 5 teaching hospitals in the Chengdu-Chongqing Economic Zone of China. The results indicated that heavy workload, personal safety, inadequate pay, role overload, and poor working environment are stressors of DQNT. Furthermore, Chinese DQNT face violence from patients and students. The study provides a theoretical basis to help DQNT to cope with stress. Copyright © 2013 Elsevier Ltd. All rights reserved.

The article considers the role of State aid law in the regulation of exclusive rights. Whereas the right of Member States to organise markets as monopolies and the choice of provider...... are regulated by free movement rules and Article 106 TFEU, State aid law regulates the terms of the right to ensure that the beneficiary is not granted an economic advantage. Exclusive rights may be granted on various terms: for a payment, in combination with compensation or as compensation. The two former...... kinds of terms are regulated under State aid law which requires market terms. The granting of exclusive rights as compensation is analysed on the basis of the Eventech judgment, and it is found that when no financial transaction is included in the grant, it resembles a decision to organise a market...

  13. Options for Tsetse Eradication in the Moist Savannah Zone of West Africa: Technical and Economic Feasibility, Phase 1 - GIS-Based Study. Programme Against African Trypanosomiasis

    International Nuclear Information System (INIS)

    2001-12-01

    This desk study was initiated with two objectives: - To examine the economic costs and benefits of a range of different sized tsetse eradication projects in the Moist Savannah Zone of West Africa (MSZ), and; - To test the hypothesis that larger tsetse control projects are more economically efficient than smaller projects in that region. The limited nature of the study precluded detailed examination of the socio-cultural and environmental issues relating to controlling trypanosomosis although these are briefly considered; nor did it aim to compare vector control with other methods of combating trypanosomosis such as the therapeutic or prophylactic use of drugs. However, by computing benefits over just 10 years an indirect comparison is made with the strategy that maintains that eradicating tsetse flies is not justified as, sooner or later, rapidly increasing population pressure will autonomously eradicate tsetse flies and hence trypanosomosis. This analysis suggests that such a strategy is not justified economically. As the basis of the economic evaluation was a study of projects in defined areas it was first necessary to iteratively examine the technical and economic issues relating to project selection and design. In this respect, the re-invasion issue was considered to be the major influence as it threatens both the sustainability and economic performance of tsetse eradication. Consequently, it was considered that the river basin was the smallest size of project that would optimise economic performance. This particular observation relates uniquely to the MSZ and may not apply to more southerly areas where fly distribution is more ubiquitous or to other parts of Africa. By basing the economic analysis on an evaluation of projects, albeit hypothetical, it was possible to use real data as the baseline database and the projects could be designed in response to actual tsetse and trypanosomosis scenarios. The group of study areas were chosen to be representative of the

    A technical, economic and environmental assessment is realized of a thermal treatment technology. The energetic valorization from municipal solid waste and electric power generation in the zone of Los Santos, Costa Rica, are made by the multicriteria hierarchical analysis methodology. The national and cantonal situation is examined in the integral management of municipal solid waste (GIRS), with emphasis on the cantons from the zone of Los Santos. A comparative analysis is developed among some cantons of Costa Rica that have had GIRS studies, and the zone of Los Santos to know the fraction of municipal solid waste that can be valued energetically and calorific power that present. The similarity in the characterization, composition and physico-chemical properties is determined in the study of residues between the cantons analyzed and the zone of Los Santos. The legislation relating the waste processing is analyzed, according Law 8839 for integral management of waste and laws similar to the implementation of a power generation plant. An analysis is developed for the environmental compliance of thermal treatment technologies, including aspects for control of contaminants. The main technologies of energy valorization from waste are investigated and some real cases of Latin America and the world are exposed. A thermal treatment technology of municipal solid waste is selected through a decision-making methodology to evaluate technical, environmental and economic aspects. Operation requirements and functioning of the devices that conform a power generation plant are described by municipal solid waste of the technology selected. The economic viability of the selected proposal has determined by an economic analysis, to extend on the most influential aspects developing alternative scenarios. The diagnosis of the situation of solid waste in the zone of Los Santos has specified that the cardboard, paper and plastics have been the most adequate for the thermal utilization

    Full Text Available Modern society is characterised not only by a fascination with scientific technology as a means of solving all problems, especially those that stand in the way of material progress (technicism, but also by an obsessive interest in everything that has to do with money (economism or mammonism. The article discusses the relationship between technicism and economism, on the basis of their relationship to utilitarian thinking: the quest for the greatest happiness for the greatest number of people. Recent major studies of neo-liberalism (seen as an intensification of utilitarianism by Laval and Dardot are used as reference to the development of utilitarianism. It is suggested that the western view of the world, as expressed in economism and technicism, with a utilitarian ethics, features three absolutisations: those of theoretical thinking, technology and economics. In a second part, the article draws on the framework of reformational philosophy to suggest an approach that, in principle, is not marred by such absolutisations.

    Full Text Available The Changchun–Jilin Economic Zone (CJEZ is one of the most rapidly developing areas in Northeast China, as well as one of the famous golden maize belts in the world. This is a case study to assess the impacts of urban sprawl on soil resources using remote sensing imagery and geographic spatial analysis methods. The common urbanization intensity index (CUII, soil quality index, and soil landscape metrics were calculated to reflect urbanization and the response of soil resource. Results showed that the area of soil sealing changed from 112,460 ha in 2000 to 139,233 ha in 2015, and in the rural region, the area occupied by urbanization nearly kept balance with the area of rural residential expansion. Urban land increased by 26,767 ha at an annual rate of 3.23% from 2000 to 2015. All seven soil types were occupied during the urbanization process, among which black soil ranked the highest (18,560 ha and accounted for 69.34% of the total occupied area. Soils of Grades I (3927 ha and II (15,016 ha were 64.75% of the total occupied soil areas. Urban land expanded in an irregular shape and a disordered way, which led to an increasing large patch index (LPI and aggregation index (AI, and a decreasing edge density (ED and Shannon’s diversity index (SHDI of the soil landscape in the study area during 2000–2015. According to the geographically weighted regression (GWR model analysis, the R2 between the CUII and soil landscape metrics decreased from the LPI and ED to SHDI and in turn to AI. The local R2 between SHDI, ED, and CUII showed a gradient structure from the inner city to peri-urban areas, in which larger values appeared with strongly intensive urbanization in urban fringes. Soil sealing induced by urbanization has become a significant factor threatening soil, the environment, and food security. How to coordinate regional development and ensure the sustainability of the multiple functions of soil is a problem that needs to be taken into account

    Full Text Available Social exclusion is a process whereby certain individuals are pushed to the edge of society and prevented from participating fully by virtue of their poverty, or lack of basic competencies and lifelong learning opportunities or as a result of discrimination. This distances them from job, income and education opportunities as well as social and community networks and activities. Quality education (conditions and access/accessibility/availability is one of the factors that significantly influence the reduced social exclusion. In other words, education has is key role key role in ensuring social inclusion (equal opportunities and active social participation. At the same time, education and lifelong learning is established as the basis for achieving the goals of sustainable economic development (economy based on knowledge and to achieve social cohesion. Quality education is a prerequisite for progress, development and well-being of the community. Conditions and accessibility to education have become priorities of national reforms in most European countries. The subject of this paper is the educational structure of population of Serbia and the accessibility of education. The analysis covers the educational structure with regard to age, gender and type of settlement (city and other/villages settlements.

    Full Text Available The coastal zone in Ukraine is likely to undergo the most profound change in the near future. Already more than 65 percent of the Ukrainian Black Sea region population lives within 30 km of the coast. Consequently, unless territory planning and careful environmental management are instituted, sharp conflicts over coastal space and resource are likely, and the degradation of natural resources will stop future social-economic development. In order to maintain and restore coastal ecosystem it was implemented law about formation of the national ecological network of Ukraine. Later were developed General Scheme for Planning of the Territory of Ukraine and regional level planning scheme but there is no especial document regulating the use of land in the coastal zone. The study of geographical conditions, economic activity, and population resettlement shows separation within the regions of several echelons of economic development in relation to the coastline. Such separation may be based on differences in intensity and types of economic use within the territory and the water area, as well as the population density on the land. These features include the following economic stripes: seaside-facade, middle, peripheral – on land, and coastal, territorial waters, exclusive economic zone – in the direction of the sea. At the same time, each economic stripe has a complex internal structure. There are several basic principles of functional zoning of the territory highlighted in the article can help to rational plan the seaside regions.

    2017-03-01

    Taking the Guangxi Beibu Gulf Economic Zone as the study area, this paper utilizes the geographical detector model to quantify the feedback effects from the terrestrial environment on precipitation variation from 1985 to 2010 with a comprehensive consideration of natural factors (forest coverage rate, vegetation type, terrain, terrestrial ecosystem types, land use and land cover change) and social factors (population density, farmland rate, GDP and urbanization rate). First, we found that the precipitation trend rate in the Beibu Gulf Economic Zone is between -47 and 96 mm/10a. Second, forest coverage rate change (FCRC), urbanization rate change (URC), GDP change (GDPC) and population density change (PDC) have a larger contribution to precipitation change through land-surface feedback, which makes them the leading factors. Third, the human element is found to primarily account for the precipitation changes in this region, as humans are the active media linking and enhancing these impact factors. Finally, it can be concluded that the interaction of impact factor pairs has a significant effect compared to the corresponding single factor on precipitation changes. The geographical detector model offers an analytical framework to reveal the terrestrial factors affecting the precipitation change, which gives direction for future work on regional climate modeling and analyses.

    Hard exclusive processes in high energy electron proton scattering offer the opportunity to get access to a new generation of parton distributions, the so-called generalized parton distributions (GPDs). This functions provide more detailed informations about the structure of the nucleon than the usual PDFs obtained from DIS. In this work we present a detailed analysis of exclusive processes, especially of hard exclusive meson production. We investigated the influence of exclusive produced mesons on the semi-inclusive production of mesons at fixed target experiments like HERMES. Further we give a detailed analysis of higher order corrections (NLO) for the exclusive production of mesons in a very broad range of kinematics. (orig.)

    In China, local governments of many areas prefer to give priority to the development of heavy industrial clusters in pursuit of high value of gross domestic production (GDP) growth to get political achievements, which usually results in higher costs from ecological degradation and environmental pollution. Therefore, effective methods and reasonable evaluation system are urgently needed to evaluate the overall efficiency of industrial clusters. Emergy methods links economic and ecological systems together, which can evaluate the contribution of ecological products and services as well as the load placed on environmental systems. This method has been successfully applied in many case studies of ecosystem but seldom in industrial clusters. This study applied the methodology of emergy analysis to perform the efficiency of industrial clusters through a series of emergy-based indices as well as the proposed indicators. A case study of Shenyang Economic Technological Development Area (SETDA) was investigated to show the emergy method's practical potential to evaluate industrial clusters to inform environmental policy making. The results of our study showed that the industrial cluster of electric equipment and electronic manufacturing produced the most economic value and had the highest efficiency of energy utilization among the four industrial clusters. However, the sustainability index of the industrial cluster of food and beverage processing was better than the other industrial clusters.

    2017-12-01

    Rainwater harvesting is now increasingly used to manage urban flood and alleviate water scarcity crisis. In this study, a computational tool based on water balance equation is developed to assess stormwater capture and water saving efficiency and economic viability of rainwater harvesting systems (RHS) in eight cities across four climatic zones of China. It requires daily rainfall, contributing area, runoff losses, first flush volume, storage capacity, daily water demand and economic parameters as inputs. Three non-potable water demand scenarios (i.e., toilet flushing, lawn irrigation, and combination of them) are considered. The water demand for lawn irrigation is estimated using the Cropwat 8.0 and Climwat 2.0. Results indicate that higher water saving efficiency and water supply time reliability can be achieved for RHS with larger storage capacities, for lower water demand scenarios and located in more humid regions, while higher stormwater capture efficiency is associated with larger storage capacity, higher water demand scenarios and less rainfall. For instance, a 40 m3 RHS in Shanghai (humid climate) for lawn irrigation can capture 17% of stormwater, while its water saving efficiency and time reliability can reach 96 % and 98%, respectively. The water saving efficiency and time reliability of a 20 m3 RHS in Xining (semi-arid climate) for toilet flushing are 19% and 16%, respectively, but it can capture 63% of stormwater. With the current values of economic parameters, economic viability of RHS can be achieved in humid and semi-humid regions for reasonably designed RHS; however, it is not financially viable to install RHS in arid regions as the benefit-cost ratio is much smaller than 1.0.

    This study explored the influence of satisfaction with economic and social rights (ESR) on the quality of life (QOL) of people in post-disaster zones in Sichuan, China. Data from a survey conducted in 2013 in the 5 hardest hit counties in the earthquake-prone area of Sichuan were used. QOL was measured by use of the brief version of the World Health Organization Quality of Life questionnaire (WHOQOL-BREF). Structural equation models were developed to determine the specific features of the influence of satisfaction with ESR on QOL. The mean values of both the WHOQOL-BREF scale and the ESR satisfaction scale were lower than the midpoint of the scales. Satisfaction with ESR had a significant effect on psychological health, social relationships, and environment, apart from physical health. Satisfaction with the right to food had the greatest effect on QOL, followed by the rights to education, work, health, social security, and housing. Satisfaction with ESR had a significant positive influence on the QOL of people in a post-disaster zone, particularly satisfaction with the right to food. Policies on food and education guarantees and mental health intervention are highlighted.

The number of these fish species in the River Danube and its flood zones in this part of the Pannonian Basin is decreasing due to the use of inappropriate “tools”, electric current, uncontrolled agricultural and industrial waste dumps, degradation of the habitat. The above mentioned species deserve attention because, according to the Rulebook on declaration and protection of protected and strictly protected wild species of plants, animals and fungi of 2010, in Serbia, T. tinca is a strictly protected species, while C. carpio, E. lucius, S. glanis, S. lucioperca and A. ruthenus are listed as protected. On the basis of the 2009 Fisheries Law in Serbia, permanently closed fishing season was introduced for tench, and closed season in certain periods and fishing ban for individuals under the prescribed size for the rest of the above mentioned species. A. ruthenus is subject to the Law on Ratification of Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES, ANNEX II and is listed in the category of species that may be in danger of extinction. Furthermore, it can be found on the IUCN Red List of Endangered Species of the International Union for Conservation of Nature – VU, which means that it is marked as vulnerable.

    according to UNU-EHS methodology: 'exposure' and 'vulnerability', consisting of 'susceptibility', 'coping capacity' and 'adaptive capacity'. Relevant indicators for each block were selected and verified by statistical methods. The authors estimated the share of people potentially exposed to flooding with the help of geographic information system. The authors, using the technique of World Risk Index (2011), calculated sub-indices for each block, and made the maps. Areas with the highest socio-economic risks were identified on the Azov and the Black sea coast: Slavyansky, Krymsky, Krasnoarmeysky, Temryuksky and Primorsko-Akhtarsky municipal districts. On the third stage, the main purpose was to integrate and use both approaches in evaluation of socio-economic risks on micro-geographical level for different categories of the population and different industries (agriculture, utilities, etc.), using 'field' data. Field study was conducted in Slavyansky municipal district of Krasnodar region and included opinion polls, special interviews with businessmen and authorities, collection of municipal statistics and data from companies, etc. Vulnerability maps, speed evacuation maps, maps of possible locations of warning systems and maps of high insurance risks were developed. Proposals for improvement of legislation for coastal zones were prepared. The conducted research has shown the importance of both social ('vulnerability'), and economic ('damage') components of risk assessment. Using the previously discussed methods individually does not bring desired results because of deficiencies of Russian statistics. It is essential for accurate risk assessment to use an 'ensemble' of methods (statistical, field observations, etc.) on micro geographic level. The work has a practical importance for improving safety of local communities.

    Full Text Available Ecological land is one of the key resources and conditions for the survival of humans because it can provide ecosystem services and is particularly important to public health and safety. It is extremely valuable for effective ecological management to explore the evolution mechanisms of ecological land. Based on spatial statistical analyses, we explored the spatial disparities and primary potential drivers of ecological land change in the Poyang Lake Eco-economic Zone of China. The results demonstrated that the global Moran’s I value is 0.1646 during the 1990 to 2005 time period and indicated significant positive spatial correlation (p < 0.05. The results also imply that the clustering trend of ecological land changes weakened in the study area. Some potential driving forces were identified by applying the spatial autoregressive model in this study. The results demonstrated that the higher economic development level and industrialization rate were the main drivers for the faster change of ecological land in the study area. This study also tested the superiority of the spatial autoregressive model to study the mechanisms of ecological land change by comparing it with the traditional linear regressive model.

    Social exclusion anxiety is a term which builds on a social-psychological concept of human beings as existentially dependent on social embeddedness. This entry explores the concept in relation to bullying among children, which is a widespread and serious problem in schools and institutions. Social...... exclusion anxiety and longing for belonging are both central aspects of the affects and processes that enact and challenge social groups. Social exclusion anxiety should not be confused with ‘social phobia’, which is a concept within clinical psychology that focuses on the individual and refers to a phobic...... psychological condition. Social exclusion anxiety instead points to a distributed affect which circulates and smolders in all social groups. This is the result of an ever-present risk of someone being judged unworthy to belong to, or deemed not a legitimate participant in, a social group. Such anxiety may...

    Full Text Available Lands (broader concept than soils, including all elements of the environment: soils, geology, topography, climate, water resources, flora and fauna, and the effects of anthropogenic activities of the state of Minas Gerais are in different soil, climate and socio-economics conditions and suitability for the production of agricultural goods is therefore distinct and mapping of agricultural suitability of the state lands is crucial for planning guided sustainability. Geoprocessing uses geographic information treatment techniques and GIS allows to evaluate geographic phenomena and their interrelationships using digital maps. To evaluate the agricultural suitability of state lands, we used soil maps, field knowledge, forest inventories and databases related to Ecological-Economic Zoning (EEZ of Minas Gerais, to develop a map of land suitability in GIS. To do this, we have combined the maps of soil fertility, water stress, oxygen deficiency, vulnerability to erosion and impediments to mechanization. In terms of geographical expression, the main limiting factor of lands is soil fertility, followed by lack of water, impediments to mechanization and vulnerability to erosion. Regarding agricultural suitability, the group 2 (regular suitability for crops is the most comprehensive, representing 45.13% of the state. For management levels A and B, low and moderate technological level, respectively, the most expressive suitability class is the regular, followed by the restricted class and last, the adequate class, while for the management level C (high technological level the predominant class is the restricted. The predominant most intensive use type is for crops, whose area increases substantially with capital investment and technology (management levels B and C.

    2018-03-01

    Full Text Available Since it implemented open-door policies, China has become the fastest growing economy in the world, and its urbanization level has steadily improved. Taking a special economic zone as the object of study, this paper delineates the urban development boundary of the Central Urban Area of Doumen. Using multiple models and methods, the urban development rigid and elastic boundaries are delineated separately, with the rigid boundary serving as the premise and foundation for delineating the elastic boundary. The results are as follows. First, the scale of the urban development rigid boundary is 79.60 km². Moreover, the scales of the urban development elastic boundaries in 2020 and 2026 are 24.51 km² and 28.53 km², respectively. Second, by delimiting the urban development elastic boundary, the compactness of urban land will be improved. Third, the urban development boundary of this paper is reasonable in theory. This paper suggests that the urban development boundary can curb urban sprawl and guide rational urban development, which is conducive to optimizing an urban spatial layout.

    The concept of critical zone (CZ) science has gained wide recognition with actively funded and emerging CZ observatory programs across the globe. There is much to be gained through international collaboration that links field, laboratory, and modeling efforts from across the emerging global CZ networks, but building international ties is difficult, especially when peer-to-peer connections are nascent, separated by great distances, and span different cultural and political environments. The U.S. and China share many climatic and geological similarities but differ greatly in the magnitude and timescale of human alteration of their landscapes making the comparative study of their respective pasts, current state, and future co-evolution an outstanding scientific opportunity to better understand, predict, and respond to human influence on the CZ. Leveraging the infrastructure and trust capital of longstanding sub-national volunteer scientific networks to bring together people and organizations is a resource-efficient mechanism to build cross-network CZ programs. The U.S.-China EcoPartnership for Environmental Sustainability (USCEES) is one of 30 current EcoPartnerships established beginning in May 2008 by a joint agreement between the U.S. Department of State and China's National Development and Reform Commission with the overarching goal of addressing the interconnected challenges of environmental, social, and economic sustainability through bi-national research innovation, communication, and entrepreneurship. The 2015 USCEES annual conference on "Critical Zone Science, Sustainability, and Services in a Changing World" was co-sponsored by the U.S. Cross-CZO Working Group on Organic Matter Dynamics and hosted three NSF-funded workshops on organic matter dynamics:1) methods for large and complex data analysis, 2) erosion and deposition processes, and 3) mineralogical and microbial controls on reactivity and persistence.

    2002-01-01

    The report entitled Climate Change Impacts and Adaptation : A Canadian Perspective, presents a summary of research regarding the impacts of climate change on key sectors over the past five years as it relates to Canada. This chapter on the coastal zone focuses on the impact of climate change on Canada's marine and Great Lakes coasts with tips on how to deal with the impacts associated with climate change in sensitive environments. This report is aimed at the sectors that will be most affected by adaptation decisions in the coastal zone, including fisheries, tourism, transportation and water resources. The impact of climate change in the coastal zone may include changes in water levels, wave patterns, storm surges, and thickness of seasonal ice cover. The Intergovernmental Panel on Climate Change projects global average sea level will rise between 9 and 88 centimetres between 1990 to 2100, but not all areas of Canada will experience the same rate of future sea level change. The main physical impact would be shoreline change that could result in a range of biophysical and socio-economic impacts, some beneficial, some negative. The report focuses on issues related to infrastructure and communities in coastal regions. It is noted that appropriate human adaptation will play a vital role in reducing the extent of potential impacts by decreasing the vulnerability of average zone to climate change. The 3 main trends in coastal adaptation include: (1) increase in soft protection, retreat and accommodation, (2) reliance on technology such as geographic information systems to manage information, and (3) awareness of the need for coastal adaptation that is appropriate for local conditions. 61 refs., 7 figs

    Full Text Available Abstract Background Intestinal parasitic infections are of one most important problems in developing countries and job is one of the most important factors determining the rate of intestinal parasitic infections. Persons who deal with waste elimination and recycling, due to close contact with infectious sources are more likely to be infected than others. Because of industrialization, population density and immigrants residing in Assaluyeh region , and due to the lack of history of a study for intestinal parasitic infection, the prevalence rate of intestinal parasitic infections among workers in the collection, transportation and recycling of wastes in the Pars Special Economic Energy Zone was evaluated. Material and methods: In a descriptive cross-sectional study, demographic questionaire was completed for each person, Stool samples were taken and sample containers were transferred to parasitology research laboratory of university. Samples were examined for intestinal parasites by preparing direct smear (wet mount and formalin-ether sedimentation technique. Data were collected by questionnaire and analyzed using SPSS 15.0 software and Chi square test. Results: The results showed that 37.3% of samples were infected at least with one intestinal parasite, 10.7% of samples were infected with more than one parasite. Giardia lamblia (6% and Entamoeba coli (13/4%, showed the highest infection rate among all parasite species. Prevalence rate of intestinal parasites in worker from Nakhl-e- Taghi municipality was higher than other region of the study area. Conclusion : Job type and duration of contact with infectious source play important roles in determining rate of intestinal parasitic infection. Workers involved in collection, transportation and recycling of wastes are more at risk of intestinal parasitic infections than others. Therfore, providing personal protective equipments and health education in this group can play an important role in community

  9. Implementation of exclusive truck facilities

    Fekpe, E. [Battelle Memorial Inst., Columbus, OH (United States). Transportation Market Sector

    2007-07-01

    This paper discussed the issue of highway congestion, safety, and efficiency in freight movement on highways, with particular reference to the challenge of supporting increasing capacity demand from truck traffic. Innovative and practical solutions are needed to address the growing need for more efficient freight movement while maintaining acceptable levels of safety on highways. The concept of exclusive truck facilities (ETFs) is becoming an attractive option as a feasible strategy to help stabilize traffic flow, reduce congestion, improve safety, enhance transportation system management, improve access to freight facilities, and improve efficiency in freight movement along corridors of national importance. ETFs can either be truck only lanes or truckways. Passenger cars may not use ETFs. However, the use of ETFs could involve high costs of construction, maintenance, and acquisition of additional right of way. A cost-benefit analysis was performed for alternative ETF configurations under different traffic and site characteristics. A set of criteria was then proposed for identifying suitable locations for exclusive truck lanes. It was proposed that ETFs are economically feasible at locations with traffic volume of 100,000 vehicles per day or more and with a truck volume of at least 25 per cent of the traffic. In addition, the rate of truck-involved fatal crashes and level of service should be used to prioritize preliminary candidate locations that satisfy the traffic criteria. Consideration should also be given to the existence of freight terminals, ports, processing centers or regional distribution centres that are close to highways. 11 refs., 1 tab.

    Since the 1980s,China has begun its direct investment in Africa.Economic and trade cooperation has been strengthened under the joint efforts of both sides.China has established six economic and trade cooperation zones in Africa according to the successful experiences of Chinese special economic zones,and the establishment and operation of these economic and trade cooperation zones are in line with the interests of both sides and have a huge potential for development.Up till now,research by experts in China and abroad has mainly focused on the establishment background,development process and status,influencing factors,and measures and suggestions for sustainable development of China-Africa economic and trade cooperation zones without in-depth investigation of a single economic and trade cooperation zone.Therefore,using Zambia-China Economic and Cooperation Zone in southern Africa as an example,the present paper analyzes the advantages of and challenges faced by the cooperation zone based on its establishment background and development process.One advantage is a mature political and economic environment in Zambia.Zambia has a mature national system and maintains friendly relations with many countries.Its GDP has achieved continuous positive growth for years now,and its macro-economy is stable.Another advantage is reflected in the protection and incentive policies made by the two governments:the Chinese government set up an economic and trade cooperation zone development fund and provides policy support for investment and financing;Zambia provides work permit and tax incentives.In addition,Zambia has a large market radiation circle;it is not only a founding member of the World Trade Organization,but also a member of the East African Common Market and the Southern African Development Community.Last but not least,the cooperation zone provides a full range of "one-stop" services for enterprises,and Zambia's mature management experience has provided favorable conditions

    In this talk I concentrate on purely exclusive processes. In Sec. II form factors and exclusive decays of heavy quarkonium states will be discussed. In Sec. III elastic wide angle elastic scattering will be considered with emphasis placed on the energy dependence for a fixed angle. The x → 1 limit of structure functions is discussed in Sec. IV. This is a limit which matches on, in a rather complicated way, with transition form factors. In Sec. V the idea of intrinsic charm is considered, mostly from a conceptual viewpoint as to its definition and possible existence. In Sec. VI there is a brief discussion of calculations of matrix elements which occur in deeply inelastic scattering by use of a bag model. In Sec. VII wee parton cancellations and Sudakov corrections for μ-pair production are considered. Sec. VIII concerns soft particle production and the mutliplicity of hadrons in a jet. (orig./HSI)

  18. The psychology of exclusivity

    Directory of Open Access Journals (Sweden)

    Troy Jollimore

    2008-02-01

    Full Text Available Friendship and romantic love are, by their very nature, exclusive relationships. This paper suggests that we can better understand the nature of the exclusivity in question by understanding what is wrong with the view of practical reasoning I call the Comprehensive Surveyor View. The CSV claims that practical reasoning, in order to be rational, must be a process of choosing the best available alternative from a perspective that is as detached and objective as possible. But this view, while it means to be neutral between various value-bearers, in fact incorporates a bias against those value-bearers that can only be appreciated from a perspective that is not detached—that can only be appreciated, for instance, by agents who bear long-term commitments to the values in question. In the realm of personal relationships, such commitments tend to give rise to the sort of exclusivity that characterizes friendship and romantic love; they prevent the agent from being impartial between her beloved’s needs, interests, etc., and those of other persons. In such contexts, I suggest, needs and claims of other persons may be silenced in much the way that, as John McDowell has suggested, the temptations of immorality are silenced for the virtuous agent.

    Full Text Available Social exclusion is a wider concept than poverty and includes not only material conditions but also inability to participate in economic, social, political and cultural life. The essence of social exclusion is social relationships (more exactly breaking off relationships, which may mean not only pushing away some members of the society, but also breaking off relationships with the society from the side of a person himself/herself. The reasons of origin of social exclusion may be legal, political, economical, social and cultural. Nowadays social exclusion is predetermined by social-economic factors. According to Poviliūnas (2001, the problems of children’s social exclusion may be solved ensuring proper education, care of public health, safety and minimal life standard. Growing aggression and violence of schoolchildren and their social exclusion are nowadays an important issue of political debate and media reports. Often schoolchildren face the risk of social exclusion at school during the period of adolescence. The risk also depends on the social status of their family in the society and the relationship of the family members. The aim of the article is to identify characteristic features of schoolchildren at risk of social exclusion and analyze social support provided for them. A quantitative research was carried out to achieve the aim. The method of data collection is a questionnaire. 105 teachers working in 3 secondary schools in Lithuania participated in the research. The research results revealed that most often schoolchildren face the risk of social exclusion at school during adolescence period. They are characterized as incommunicative, unsociable, passive, and shy, do not trust others, are vulnerable, have learning problems and avoid collaborative activities. These schoolchildren usually come from families of social risk or single parent families. The support provided at school by teachers to schoolchildren at risk of social exclusion

  1. Exclusion and authorization

    International Nuclear Information System (INIS)

    Cooper, J.R.

    2003-01-01

    'Everyone in the world is exposed to radiation from natural and artificial sources. Any realistic system of radiological protection must have a clearly defined scope if it is not to apply to the whole of mankind's activities'. This quote, from ICRP Publication 60 (ICRP, 1991), remains apposite. The main tool for defining scope is the concept of exclusion: situations, sources or exposures that are excluded from the system of radiological protection are, to all intents and purposes, ignored. Sources and exposures that are not excluded are within the scope of the system of protection and by inference within regulatory systems implementing ICRP recommendations. These sources and exposures should be subject to appropriate authorization by the relevant regulatory authority. In order to avoid excessive regulatory procedures, however, provisions should be made for granting an exemption in cases where it is clear that regulatory provisions are unnecessary. Exemption is a regulatory tool intended to facilitate efficient use of regulatory resources. Nevertheless, the regulatory act of granting exemptions is, in itself, a form of authorization and the material or situation so exempted remains within the regulatory system. This distinction between exclusion and exemption is an important one. Historically, the concept of exclusion has been applied to sources or exposures that are essentially unamenable to control because of their widespread nature. The usually quoted examples are cosmic radiation at ground level and 40 K in the body. Clearly, many exposures from natural sources could fall into this category. The challenges are firstly to establish a sound basis for deciding which should be excluded and which should be controlled, and secondly to see if the concept could or should be applied to artificial sources and exposures. These two questions are the subject of this paper. (author)

    Full text: The highest Relative Biological Efficiency is intrinsic to the emitters of alpha radiation and Americium-241 belongs to this category of emitters. The aims of this study are: to fit methods Americium-241 estimation to biological objects of different types; to elucidate the pathways of Americium-241 migration along the trophic chains; to carry out forestall investigations of the early and late effects of Americium-241; to develop means for preventing absorption of Americium-241 in tissue of different organisms and stimulation of recovery processes in damaged cells. Mechanisms of biological action of Americium-241 on the levels of molecule, membrane, genome, cells, tissue and organ are suggested to be investigated when this radionuclide is accumulated by organisms through gastro-intestinal system or inhalation of as 'hot particles'. An investigation into the intercellular localization of Americium-241 in this case was determinated for plants. Study physical, chemical, transport, enzymatic peculiarities and peroxide modifications of membranes in their relation to deterioration of metabolic processes in damaged organism. Moreover, the main indexes of blood and hemopoietic tissue directly concerned with radiation injury under the effect of Americium-241 will be revealed. An assessment of the impact of Americium-241 on immune system in animals will be elucidated as well. Investigations of the membrane bounding and complexion properties of Americium-241 will provide a possibility to find substances capable of inhibition of the Americium-241 absorption or increasing the rate of its re-sorption. At the time, cytogenetic effects resulted from injuries of genetic apparatus of cell and their role in induction of genome instability and increasing of the rate of translocations connected with cancerogenesis was studied. The results of our investigations will form the basis for elaboration of the proposals concerned the preventive and therapeutic means aimed at decreasing of negative effects of Americium-241 on organisms which are inhabited on territories contaminated with Americium-241 and plutonium 241 or in the event of an nuclear emergency

    Breastfeeding behaviour is explored in Kenya using data collected in the town of Eldoret, Kenya. This paper specifically examines duration of exclusive breastfeeding among young mothers below 20 years of age as compared to older cohorts. Additionally, focus is laid on the effect of first time motherhood and breastfeeding difficulties on exclusive breastfeeding. Results show that Eldoret mothers are aware of benefits of breastfeeding; nevertheless, the mean duration for exclusive breastfeeding in this sample is 2.4 months. Higher durations of exclusive breastfeeding are associated with increasing age and first time motherhood. Predictably, breastfeeding difficulties bear a negative association with exclusive breastfeeding. While HIV is transmissible through breastfeeding, breast milk remains a vital source of nourishment for infants in Sub-Saharan Africa. More research on mothering should examine the changing socio-economic milieu and its influence on women's infant feeding decisions

    Usually, the power of taxation is straightly connected to the idea of territory. It is important to establish the limits of tax jurisdiction not only for taxes in view of which territoriality is part of the taxable event as defined in legislation - import tax (I.I.) and excise tax (IPI) -, but also for those the location of a possession - property tax (IPTU) - or the place in which services are rendered - service occupation tax (ISS) and sales tax (ICMS) - appear as the main component of the taxable event. According to the United Nations Convention on the Law of the Sea, 1982, and the Brazilian internal legislation as well, Federal Government has full sovereignty over its territorial sea -12 mile zone. In other areas (contiguous zone, exclusive economic zone and brazilian continental shelf), sovereignty is restricted to the supervision of some activities, not involving power of taxation. (author)

    Full Text Available The article describes the solution of one of the most important problems of rational use of natural resources. Modern mathematical tools for damage estimation, which are caused by atmospheric pollution to natural objects, and also methods for calculation of the cost for their renewal were developed. The solution of problem was divided into 3 stages. At the first stage it was defined basic anthropogenic sources of pollution, was illustrated conceptual behavior of pollutants in the atmosphere emitted by technological stationary point source. Choice of mathematical model that allows to determine the distribution of pollutants concentration in the air in zones of pollution by point stationary sources in the short-term discharges was proved. At the second stage it was developed mathematical tools to determine the level of objects damage, which were in the zone of pollution, depending on the intensity and duration of exposure of technogenic sources. At the third stage it was developed mathematical models to determine the recoverable amount of natural objects depending on their level of damage. Model example of developed means usage was described. Advantages of developed means over existed analogs were noticed.

  9. National simple: Constitutionality Analysis of Exclusions Sectorial

    Full Text Available The Constitution defines the favored legal treatment for small businesses without making any explicit exception, including and especially for tax obligations. Nevertheless, all the laws, which have introduced tax benefits guided by this higher provision, have discriminated small companies due to the economic sector of activity. Known as “National Simple” and introduced by the Complementary Law No. 123/06, the current legislation did not extend its benefits to small production units of a number of industries, such as the automotive industry, the passenger transport industry, the energy industry and the industry of manufacture of weapons, beverages and tobacco products. By demonstrating the mistakes of the arguments in favor of such exclusions, the article holds up that none of these provisions meets constitutional standards. Furthermore, based on a critical analysis of the Positive Law, it is shown that the hidden desire behind the exclusions was to keep the economic sectors of high profitability under control of big corporations to the detriment of smaller initiatives.

    The LHCb detector, with its excellent momentum resolution and flexible trigger strategy, is ideally suited for measuring particles produced exclusively. In addition, a new system of forward shower counters has been installed upstream and downstream of the detector, and has been used to facilitate studies of Central Exclusive Production. Such measurements of integrated and differential cross-section in both Run 1 and Run 2 of the LHC, are summarised here.

  13. Exclusive Territories and Manufacturers’ Collusion

    2010-01-01

    This paper highlights the rationale for exclusive territories in a model of repeated interaction between competing supply chains. We show that with observable contracts exclusive territories have two countervailing effects on manufacturers' incentives to sustain tacit collusion. First, granting local monopolies to retailers distributing a given brand softens inter- and intrabrand competition in a one-shot game. Hence, punishment profits are larger, thereby rendering deviation more profitable....

    The definition of exclusion statistics, as given by Haldane, allows for a statistical interaction between distinguishable particles (multi-species statistics). The thermodynamic quantities for such statistics ca be evaluated exactly. The explicit expressions for the cluster coefficients are presented. Furthermore, single-species exclusion statistics is realized in one-dimensional integrable models. The interesting questions of generalizing this correspondence onto the higher-dimensional and the multi-species cases remain essentially open

    The genetic diversity in Zanthoxylum species viz.  Zanthoxylum nitidum, Zanthoxylum oxyphyllum and Zanthoxylum rhesta collected from the Upper Brahmaputra Valley Zone of Assam (NE India) was amplified using 13 random amplified polymorphic DNA (RAPD) markers and 9 inter-simple sequence repeat (ISSR) markers. RAPD markers were able to detect 81.82% polymorphism whereas ISSR detected 98.02% polymorphism. The genetic similarities were analyzed from the dendrogram constructed by RAPD and ISSR fingerprinting methods which divided the 3 species of Zanthoxylum into 3 clear different clusters. The principle component analysis (PCA) was carried out to confirm the clustering pattern of RAPD and ISSR analysis. Analysis of molecular variance (AMOVA) revealed the presence of significant variability between different Zanthoxylum species and within the species by both RAPD and ISSR markers. Z. nitidum was found to be sharing a high degree of variation with the other two Zanthoxylum species under study. The Nei's gene diversity (h), Shannon's information index (I), observed number of alleles (na) and effective number of alleles (ne) were also found to be higher in ISSR markers (0.3526, 0.5230, 1.9802 and 1.6145) than in RAPD markers (0.3144, 0.4610, 1.8182 and 1.5571). The values for total genotype diversity for among population (HT), within population diversity (Hs) and gene flow (Nm) were more in ISSR (0.3491, 0.2644 and 1.5610) than RAPD (0.3128, 0.2264 and 1.3087) but the mean coefficient of gene differentiation (GST) was more in RAPD (0.2764) than ISSR (0.2426). A comparison of this two finger printing methods was done by calculating MR, EMI and MI. The correlation coefficient between data matrices of RAPD and ISSR based on Mantel test was found to be significant (r = 0.65612).

    In the present study we sought to clarify links between religious exclusivity, as form of intergroup favoritism, and indices of psychosocial functioning. The study of in group favoritism has generally been invoked within Social Identity Theory and related perspectives. However, there is a lack of literature regarding religious exclusivity from the standpoint of social identity. In particular, the ways in which religious exclusivity is linked with other dimensions of religious belief and practice, and with psychosocial functioning, among individuals from different religious backgrounds are not well understood. A sample of 8545 emerging-adult students from 30 U.S. universities completed special measures. Measure of religious exclusivity was developed and validated for this group. The results suggest that exclusivity appears as predictor for impaired psychosocial functioning, low self-esteem and low psychosocial well-being for individuals from organized faiths, as well as for those identifying as agnostic, atheist, or spiritual/nonreligious. These findings are discussed in terms of Social Identity Theory and Terror Management Theory (TMT).

    Industrial ecology is the epitome of sustainable development in industry level, is one effective gateway to realizing green transformation. On the basis of industrial ecology development, including resource efficiency and environmental efficiency of ecological evaluation index system, this paper evaluates the level of industrial ecology development of resource-based industries in Xinjiang using entropy method. Research shows that the overall ecological development level of resource-based industries has remained at continuous improved trend with slow improvement in resource efficiency, and relative faster improvement in environmental efficiency. With economic development entering into the period of new normal at the end of the “twelfth five year plan”, the resource efficiency of ecological development of resource-based industries demonstrated a downward trend. The overall level of industrial ecology also faced with certain fluctuations, various ecological development level of resource-based industries also presented a downward trend. To promote ecological development of resource-based industries in Xinjiang, countermeasures and suggestions are initiated.

    The definition of exclusion statistics that was given by Haldane admits a 'statistical interaction' between distinguishable particles (multispecies statistics). For such statistics, thermodynamic quantities can be evaluated exactly; explicit expressions are presented here for cluster coefficients. Furthermore, single-species exclusion statistics is realized in one-dimensional integrable models of the Calogero-Sutherland type. The interesting questions of generalizing this correspondence to the higher-dimensional and the multispecies cases remain essentially open; however, our results provide some hints as to searches for the models in question
