    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.

  4. 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

    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.

    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

    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

    . 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)

  18. Definition of Exclusion Zones Using Seismic Data

    Science.gov (United States)

    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.

  19. 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.

    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 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).

    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

    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.

    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

    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

    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

    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.

    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

    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 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.

    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 Available L’utilisation des myriapodes en friction sur le pelage et d’autres zones corporelles est documentée chez les primates en conditions naturelles, notamment à partir des observations récurrentes menées chez le genre Cebus. La typologie de ces comportements suggère différentes hypothèses, fonctionnelles (zoopharmacognosie, alimentaire, sociale ou non (sensorielle, auto-stimulation. Nous présentons des observations qualitatives comparées de l’utilisation non alimentaire de myriapodes diplopodes chez une forme hybride du genre Eulemur au Sud de Madagascar (occurrences en janvier 2005 et chez le sapajou Cebus apella en Guyane Française (occurrences en mars-avril 1996. L’application des sécrétions à benzoquinones sur une large partie du pelage chez Cebus contraste avec la friction exclusive de la zone périgénitale faisant suite au flairage du diplopode chez Eulemur qui manifeste en outre une réponse stéréotypée analogue au flehmen. Dans notre étude, l’imprégnation de fluides à forte intensité olfactive potentialiserait la signalisation de l’identité individuelle chez Eulemur alors que le "fur-rubbing" chez Cebus est compatible avec l’hypothèse commune d’une forme d’appropriation des défenses antiparasitaires de ces invertébrés. La sécrétion de ces défenses chimiques n’est pas automatiquement déclenchée par la manipulation des diplopodes. Le stress induit par les morsures légères (Eulemur et Cebus et l’arrachage des pattes sur plusieurs segments (Cebus augmente la probabilité de sécrétion, ce qui témoignerait d’un apprentissage d’autant plus efficace des conditions d’émission de ces fluides que l’usage est spécifique et très opportuniste.Body-rubbing with millipedes is repeatedly documented in primates living under natural conditions, mainly in capuchin monkeys (Cebus spp..

    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

    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

    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.

    Prevention of radionuclides expansion in environment is one of the most complicated tasks in the complex of problems connected with measures, to decrease consequences of accident in Chernobyl nuclear power plant. Ten years experience of work in the exclusion zone show that the most real biogeochemical barrier on the way of radionuclides transfer are forests, which occupy half of the territory and keep main part of falls in the boundaries of forest landscapes

    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

    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)

    Introduction Le Cameroun se situe dans un contexte d’épidémie généralisée du VIH. La sous-population des femmes enceintes, facilement accessible au sein de la population générale, représente une cible probante pour mener la surveillance du VIH et estimer l’évolution épidémiologique. L'objectif de notre étude était d’évaluer la distribution épidémiologique du VIH chez les femmes enceintes. Méthodes Étude transversale menée en 2012 chez 6521 femmes enceintes (49,3% âgées de 15-24 ans) en première consultation prénatale (CPN1) dans 60 sites des 10 régions Camerounaises. L'algorithme en série a été utilisé pour le sérodiagnostic du VIH. Résultats La prévalence du VIH était de 7,8% (508/6521), avec une différence non significative (p = 0,297) entre milieu rural (7,4%) et milieu urbain (8,1%). En zone rurale, cette prévalence variait de 0,7% à l'Extrême-Nord à 11,8% au Sud. Cependant, en zone urbaine elle variait de 4% à l'Ouest à 11,1% au Sud-Ouest. Suivant l’âge, la prévalence était plus élevée (11,3%) chez les femmes de 35-39 ans. Suivant le niveau de scolarisation, la prévalence du VIH était plus faible (4,4%) chez celles non-scolarisées, et plus élevée (9,3%) chez celles ayant un niveau primaire. Selon la profession, l'infection était plus élevée chez les coiffeuses (15,5%), secrétaires (14,8%), commerçantes (12,9%) et institutrices/enseignantes (10,8%). Conclusion La prévalence du VIH reste élevée chez les femmes enceintes au Cameroun, sans distinction entre milieux rural et urbain. Les stratégies de prévention devraient s'orienter préférentiellement chez les femmes enceintes âgées, celles du niveau d'instruction primaire, et celles du secteur des petites et moyennes entreprises.

    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.

    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.

  17. Trapping and exclusion zones in complex streaming patterns around a large assembly of microfluidic bubbles under ultrasound

    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.

    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 Introduction : Les maladies cardiovasculaires (MCV et leurs facteurs de risque présentent des gradients socioéconomiques clairs chez les adultes canadiens, mais présentent des ambiguïtés chez les enfants. L'objectif de cette étude est de vérifier l'existence ou non de gradients socioéconomiques dans les marqueurs physiologiques du risque de MCV chez les enfants et les adolescents canadiens. Méthodologie : À partir des données transversales combinées de l'Enquête canadienne sur les mesures de la santé 2007-2011, nous avons étudié, chez 2 149 enfants (6 à 11 ans et 2 073 adolescents (12 à 17 ans et selon le sexe, les marqueurs de risque cardiovasculaire suivants : excès de poids (y compris l'obésité, score de capacité aérobique (SCA, pression artérielle (PA, lipides sanguins (totaux, cholestérol LDL et HDL, triglycérides, métabolisme du glucose et protéine C réactive (CRP. Des analyses de régression logistique et de régression linéaire multidimensionnelles ont permis de dégager les tendances relatives au risque cardiovasculaire en fonction de la suffisance du revenu du ménage et du niveau de scolarité des parents, après ajustement en fonction de l'âge et de l'origine ethnique, et après stratification par groupe d'âge et par sexe. Résultats : La prévalence de l'obésité était sensiblement plus élevée chez les jeunes garçons que chez les jeunes filles (prévalence de 18,5 %, intervalle de confiance [IC] à 95 % : 15,6 à 21,5 contre 7,7 %, IC à 95 % : 5,2 à 10,3. Toutefois, des gradients socioéconomiques négatifs ont été observés en ce qui concerne le risque d'adiposité chez les jeunes filles et les adolescentes, et non chez les garçons. Parmi les enfants et les adolescents, les garçons étaient en meilleure condition physique que les filles (SCA moyen de 541, IC à 95 % : 534 à 546 contre 501, IC à 95 % : 498 à 505 chez les enfants; 522, IC à 95 % : 514 à 529 contre 460, IC à 95 % : 454

    2004-01-01

    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)

    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 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

    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.

    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)

  16. Main stages of 137Cs accumulation by mushrooms in exclusion zone after ChNPP accident

    2001-01-01

    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

  18. Using GIS to evaluate the impact of exclusion zones on the connection cost of wave energy to the electricity grid

    International Nuclear Information System (INIS)

    Prest, Robert; Daniell, Trevor; Ostendorf, Bertram

    2007-01-01

    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

    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

    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

    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.

    More then 30 plants species from the Chernobyl exclusion zone have been analyzed and plant samples with high level of arbuscular mycorrhizal fungi (AM) colonization were selected. Spores of AM fungi have isolated from the rhizosphere of those plants, which had high accumulation abilities related to the radionuclides and were high AM colonized as well. These AM spores are used to produce inocula in order of it's forthcoming application in the phytoremediation activity

    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)

    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

    This study provides the first marine gastropod checklist from the Sarawak Exclusive Economic Zone (EEZ). 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: 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 .

    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.

    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.

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

    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.

    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.

    2014-05-01

    Full Text Available Une alimentation saine, en particulier la consommation régulière d’aliments riches en vitamine D, est un facteur protecteur contre la survenue de pathologie démentielle chez la personne âgée. Outre ses propriétés traditionnellement reconnues de régulation du métabolisme phosphocalcique, la vitamine D est une hormone neurostéroïde indispensable au fonctionnement neurophysiologique (régulation de neurotransmetteurs et de neurotrophines avec, en plus, une action neuroprotectrice anti-inflammatoire et anti-oxydante. Au contraire son insuffisance, extrêmement prévalente chez la personne âgée, pourrait engendrer des dysfonctionnements du système nerveux central, expliquant en partie les troubles cognitifs rencontrés dans cette population. L’épidémiologie est cohérente avec cette notion et rapporte une association entre hypovitaminose D et trouble cognitif, que ce soit en population âgée générale ou chez le malade Alzheimer. Les essais d’intervention confirment la relation de causalité et quantifient l’efficacité cognitive de la supplémentation vitaminique D chez la personne âgée, ce qui suscite des perspectives en matière de prévention primo-secondaire des troubles cognitifs chez la personne âgée par un apport exogène de vitamine D. En particulier, tandis que les traitements anti-démence symptomatiques actuellement disponibles ne font que ralentir transitoirement le déclin cognitif, les futures possibilités de traitement pourraient reposer sur des combinaisons médicamenteuses luttant contre plusieurs mécanismes neurodégénératifs à la fois. À ce titre, la vitamine D améliore l’efficacité de la mémantine en termes de protection neuronale et de prévention du déclin cognitif au cours de la maladie d’Alzheimer.

  10. Evidence for selection in response to radiation exposure: Pinus sylvestris in the Chernobyl exclusion zone

    2011-01-01

    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.

    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.

    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 This paper summarises current knowledge of goods and servicesin the Polish Exclusive Economic Zone of the Baltic Sea ecosystem.It reviews specific properties of the Baltic that could be usedfor economic valuation. Goods and services range from the familiarresources of fish and minerals, which were valued with the ProductivityMethod, to less obvious services provided by the ecosystem suchas biofiltration in coastal sands, valued with either the ReplacementCost or Damage Cost Avoided methods. Disservices to the marineecosystem are also considered, e.g. erosion and coastal flooding,including the costs of planned mitigating measures. This paperemphasises the importance of using valuation methods to helpmake better-educated decisions for the sustainability of theBaltic Sea.

  7. Effect of Buffers on Aqueous Solute-Exclusion Zones around Ion-Exchange Resins

    Science.gov (United States)

    Zheng, Jian-ming; Wexler, Adam

    2009-01-01

    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

    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)

  14. Les interactions entre la reproduction et la biologie des populations chez les Monogènes Gyrodactylidae : revue

    Directory of Open Access Journals (Sweden)

    HARRIS P. D.

    1993-01-01

    Full Text Available Les Gyrodactylidae sont des Monogènes vivipares, les embryons se développent de manière emboitée dans l'utérus maternel. Les premier et deuxième individus fils se développent sans auto, ni fécondation croisée ; seuls les troisième et suivants peuvent se développer sexuellement. L'importance relative de la reproduction sexuée, dépend de la structure d'âge de la population et de la mortalité. Chez Macrogyrodactylus polypteri, le développement postnatal de l'appareil génital femelle facilite la fécondation croisée chez tous les individus suivant la seconde naissance. La reproduction asexuée maximise la croissance de la population mais la sexualité intervient régulièrement. Gyrdicotylus gallieni, qui parasite la bouche de Xenopus laevis, présente une croissance exceptionnellement lente de la population et les populations parasites sont surtout composées d'individus âgés et sexuellement matures. Isancistrum subulatae, parasite du Calmar Alloteuthis subulata, forme d'importantes populations, mais leur croissance est probablement lente, et la structure d'âge suggère que la sexualité est courante. Chez Gyrodactylus, plusieurs stratégies existent. Gyrodactylus turnbulli, chez les Guppis, a une courte durée de vie et manifeste une mortalité spécifique croissant exponentiellement avec l'âge, de telle sorte que moins d'un pour cent survivent assez longtemps pour donner une troisième naissance. La reproduction est principalement asexuée mais le sexe intervient dans les populations de très fortes densités. Dans la nature la reproduction asexuée prédomine sans doute et cette espèce peut être considérée comme cycliquement parthénogénétique. Chez le saumon, Gyrodactylus salaris, présente des mortalités faibles et 10-15% des survivants se reproduisent sexuellement. Des individus fécondés sont trouvés même dans les faibles infestations et la sexualité est habituelle dans la biologie de cette espèce. Chez

    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

    2014-11-01

    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.

    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)

    2012-01-01

    RÉSUMÉ Même si, au Canada, les mineurs n’ont pas le droit de jouer à des jeux de hasard légalisés, les adolescents participent souvent à des jeux de hasard soit légalisés (produits de loterie, casino, terminaux de jeux vidéo), soit autonomes (jeux de cartes, paris sportifs, dés) à la maison et en milieu scolaire. Chez les adultes, le taux de prévalence de dépendance aux jeux de hasard au cours de la vie se situe entre 1 % et 2 %. D’après les données existantes, la prévalence chez les adolescents serait de deux à quatre fois plus élevée. On ne sait pas grand-chose des facteurs de risque d’apparition et de perpétuation d’une dépendance pathologique aux jeux de hasard. Le présent document de principes vise à informer les pédiatres, les médecins de famille et les autres professionnels de la santé des connaissances émergentes sur les jeux de hasard pendant l’enfance et l’adolescence et du risque de conséquences graves qui s’y rattachent. On y exhorte également les gouvernements fédéral, provinciaux et territoriaux à inclure cette question dans leur programme et à tenir compte des facteurs sociopolitiques associés aux jeux de hasard.

    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

    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)

    Introduction Les pathologies respiratoires représentent un motif fréquent d'hospitalisation en pédiatrie. L'objectif de cette étude était d'évaluer le profil épidémiologique des pathologies respiratoires chez l'enfant à l'hôpital d'enfants de Rabat, Maroc. Méthodes Il s'agit d'une étude observationnelle transversale qui a concerné tous les cas d'enfants âgés de 3 mois à 15 ans hospitalisés pour une pathologie respiratoire au service de pneumoallergologie et infectiologie pédiatriques de l'hôpital d'enfants de Rabat sur une période d'une année, du 1 janvier 2014 au 31 décembre 2014. Résultats Sur 3537 patients hospitalisés, 2493 (70,5%) l'ont été pour une pathologie respiratoire. Les hospitalisations pour exacerbation d'asthme (p < 0,001), bronchiolite aigüe (p < 0,001) et dyspnée laryngée (p = 0,004) étaient plus fréquentes chez le garçon alors que les hospitalisations pour pneumopathie aigüe (p = 0,005), pour inhalation de corps étranger (p = 0,007) et pour coqueluche (p = 0,020) étaient plus fréquentes chez la fille. Les hospitalisations pour pneumopathie aigüe (p < 0,001), exacerbation de séquelles graves de virose (p < 0,001) et pour coqueluche (p < 0,001) étaient plus fréquentes chez le nourrisson. Les hospitalisations pour pneumopathie aigüe (p < 0,001) et pour coqueluche (p = 0,015) étaient plus fréquentes en période automnohivernale. Conclusion Les motifs d'hospitalisation étaient dominés par les exacerbations d'asthme et la bronchiolite aigüe, lesquelles étaient plus fréquentes chez le garçon. Les infections respiratoires, représentées par les pneumopathies aigües et la coqueluche, étaient plus fréquentes en période automnohivernale et touchaient plus le nourrisson. PMID:29675122

    Summary L’association brûlure et épilepsie est une constatation fréquente au Maroc. Ces brûlures, souvent itératives, touchent le plus souvent des femmes jeunes de milieu rural. L’accident survient habituellement au domicile, le plus souvent dans la cuisine à la suite d’une chute sur un moyen de cuisson posé au sol. Elles peuvent être inaugurales de la maladie mais surviennent plus souvent chez des patients connus mais au traitement mal suivi. Les conséquences de ces brûlures, toujours profondes, sont souvent dramatiques en termes de séquelles, chez des patients ayant déjà une insertion sociale rendue difficile par l’épilepsie. La prise en charge doit être multidisciplinaire et concerner à la fois la brûlures et l’épilepsie. Des mesures de prévention simples, visant à équilibrer l’épilepsie et éviter au patient de se trouver seul à proximité d’une source de chaleur, doivent être mises en place. PMID:27252613

    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.

    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 (0.22-15μGyh(-1)) and (ii) along a short distance gradient of radioactive contamination (1.2-29μGyh(-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 150μGyh(-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.

    L'infection urinaire chez l'insuffisant rénal est fréquente et particulière dans sa prise en charge diagnostique et thérapeutique. L'objectif de notre étude est de déterminer le profil bactériologique et d’étudier les facteurs de risque des infections urinaires chez le patient insuffisant rénal chronique en milieu de néphrologie. Etude prospective débutée en Septembre 2012 menée au service de néphrologie à l'hôpital régional d'Oujda de l'oriental Marocain. Ont été inclus tous les patients hospitalisés en néphrologie avec une infection urinaire documentée. Nous avons analysé les données démographiques, cliniques, biologiques, et thérapeutiques de nos patients à l'admission et au cours de leurs hospitalisations. 48 épisodes d'infections urinaires chez 43 patients ont été colligés dont 3 enfants. L'incidence de l'infection urinaire dans notre étude était de 4,65%. La médiane d’âge était de 53 (32-66) années. 60,4% étaient de sexe féminin. Le germe isolé était un Escheria Coli dans 58,3% et un Klebsiella dans 29,2%. Le germe isolé était résistant à l'amoxicilline-acide clavulanique dans 83% des cas. L'antibiotique prescris en premiére intention chez nos patients était une céphalosporine de 3 éme génération dans 50%. L’évolution chez nos patients était favorable dans 89,6% des cas. 33,3% avaient présenté un sepsis et on a noté le décès dans 10,4% des cas. Les infections urinaires chez l'insuffisant rénal chronique reste très grave vu leur lourde morbi-mortalié d'où l'intêrét d'un dépistage précoce chez cette population. Un usage raisonné des antibiotiques est nécessaire afin de prévenir l'extension des résistances bactériennes. PMID:26213601

    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

    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.

    Age,maturation and population structure of the Humboldt squid Dosidicus gigas were studied based on random sampling of the Chinese jigging fishery off the Peruvian Exclusive Economic Zones (EEZ) during 2008-2010.Estimated ages ranged from 144 to 633 days,confirming that the squid is a short-lived species with longevity no longer than 2 years.Occurrence of mature females and hatching in each month indicated that Humboldt squid spawned year-round.Back-calculated hatching dates for the samples were from January 22nd,2008 to April 22nd,2010 with a peak between January and March.Two size-based and two hatching date-based populations could be defined from mantle length (ML) at maturity and back-calculated hatching dates,respectively.Females matured at a larger size than males,and there was a significant difference in ML at maturity between the two hatching groups (P＜0.05).The waters adjacent to 11°S off the Peruvian EEZ may be a potential spawning ground.This study shows the complexity of the population structure and large variability in key life history parameters in the Humboldt squid off the Peruvian EEZ,which should be considered in the assessment and management of this important resource.

    2016-08-01

    Full Text Available Changes of faunal composition of insects-hortobionts and long-term dynamics of species diversity in the Chernobyl exclusion zone biotopes is studied. It is shown that 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 – natural, 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.

    Introduction Le doppler transcrânien est un outil efficace permettant de dépister les enfants drépanocytaires à risque d'AVC. Méthodes Nous avons réalisé une étude descriptive transversale sur des enfants Malagasy âgés entre 24 mois et 15 ans (groupe 1: 57 drépanocytaires, groupe 2: 43 témoins) afin d’évaluer le profil vélocimétrique des artères cérébrales chez les drépanocytaires. Un examen Doppler transcrânien a été réalisé avec étude des flux sanguins cérébraux chez les enfants des deux groupes. Résultats Pour les sujets drépanocytaires, la vitesse moyenne (VM) de l'artère cérébrale moyenne était de 100,9 ± 26,8 cm/s, l'indice de pulsatilité (IP) de 0,73 ± 0,20, la différence entre les artères cérébrales moyennes droite et gauche (ACMr) de 19,8 ± 21,5 cm/s, le rapport des vitesses de l'artère cérébrale antérieure/artère cérébrale moyenne (ACA/ACM) de 0,7 ± 0,2. Pour les enfants non drépanocytaires, VM: 80,6 ± 19,3 cm/s, IP: 0,79 ± 0,14, ACMr: 17 ± 20,1 cm/s, ACA/ACM: 0,8 ± 0,2. La vélocité des enfants drépanocytaires était supérieure au groupe contrôle. Les vitesses ont été corrélées avec le taux d'hémoglobine et l’âge et non pas avec le sexe et le volume globulaire moyen. Conclusion Les vitesses circulatoires cérébrales sont élevées chez les drépanocytaires que les enfants non drépanocytaires et sont influencées par le taux d'hémoglobine et l’âge. PMID:27516829

    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

    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.

    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.

    Clinical, hematological and osseous effects following an intramuscular injection of 100 {mu}Ci 90 Sr were studied in the rat. In spite of the magnitude of the injection and the resulting damage, the elimination of strontium could compare with what occurs after an injection at tracer doses. Comparing with the controls at the outcoming time, clinical monitoring mainly brought out a loss of body weight. Fairly early (20. - 30. day) there occurred severe hematological damage, especially on lymphocyte line, which subsided spontaneously. As foreseen, the anatomo-pathological survey of the early period showed bone and medullar lesions in the areas of enchondral ossification. In the late period, bone sarcomas occurred in nine animals out of ten. The outstanding histological type was osteogenic osteosarcomas; besides, two animals experienced bilateral tumors.

    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)

    Résumé Objectif Présenter des recommandations sur la prise en charge de l’infection gonococcique chez les adultes et les jeunes. Qualité des données Les recommandations thérapeutiques des lignes directrices canadiennes sur les infections transmissibles sexuellement reposent sur une recherche documentaire de même que sur des catégories de recommandations et des niveaux de qualité de données déterminés par au moins 2 évaluateurs. Les recommandations ont été revues par des pairs et sont en instance d’approbation par le groupe de travail d’experts. Message principal Les nouvelles recommandations portant sur la prise en charge de l’infection gonococcique chez les adultes et les jeunes préconisent les cultures à titre d’outil diagnostique lorsqu’elles sont pratiques, le traitement par antibiothérapie combinée (ceftriaxone associée à l’azithromycine) et le signalement sans délai de tous les cas dont le traitement a échoué aux autorités de santé publique. Conclusion Si elles sont suivies, ces nouvelles recommandations pourraient réduire l’échec thérapeutique, contribuer à une surveillance plus étroite des tendances à la résistance de Neisseria gonorrhoeae aux antibiotiques et contribuer à prévenir la transmission de gonorrhée résistante à plusieurs médicaments.

  14. Freeze core sampling to validate time-lapse resistivity monitoring of the hyporheic zone.

    A freeze core sampler was used to characterize hyporheic zone storage during a stream tracer test. The pore water from the frozen core showed tracer lingered in the hyporheic zone after the tracer had returned to background concentration in collocated well samples. These results confirmed evidence of lingering subsurface tracer seen in time-lapse electrical resistivity tomographs. The pore water exhibited brine exclusion (ion concentrations in ice lower than source water) in a sediment matrix, despite the fast freezing time. Although freeze core sampling provided qualitative evidence of lingering tracer, it proved difficult to quantify tracer concentration because the amount of brine exclusion during freezing could not be accurately determined. Nonetheless, the additional evidence for lingering tracer supports using time-lapse resistivity to detect regions of low fluid mobility within the hyporheic zone that can act as chemically reactive zones of importance in stream health. © 2012, The Author(s).

    1958-05-15

    As sulphite appears to be an intermediate substance in the degradation of sulphur-containing amino acids, and has an important metabolic role, notably for plants, this research thesis aims at comparing transformations which may occur for a same chemical compound (the sulphite) in various organisms belonging to different species or kingdoms. More particularly, the author studied the formation of sulphite in vegetal tissues, and the oxidisation of sulphite into sulfate within these tissues. In vitro experiments have been performed with oat, while in vivo experiments have been performed on tobacco plants [French] Le sulfite apparait comme une substance intermediaire de la degradation des acides amines soufres. Son role dans la biosynthese de certains d'entre eux, problematique chez les mammiferes, est certain chez les oiseaux, qui, a cet egard, se comportent comme des autotrophes partiels, puisqu'ils reduisent le sulfate en sulfite. On s'apercoit ainsi qu'un degre d'evolution moindre confere au sulfite une importance metabolique plus grande. On peut s'attendre a trouver chez les vegetaux un role encore accru pour le sulfite. Le present travail entre dans ce cadre d'etudes comparees des transformations que peut subir un meme type de compose chimique: le sulfite, dans divers organismes appartenant a des especes ou a des regnes differents. Les donnees acquises exposees ici auront trait aux deux points suivants: I - La formation du sulfite dans les tissus vegetaux, II - L'oxydation dans ces tissus, du sulfite en sulfate. L'avoine nous a servi comme materiel de depart pour les experiences faites in vitro. Cette plante presente en effet l'avantage de se bien cultiver en toutes saisons, de se broyer facilement, et d'etre depourvue au maximum de mucilages, de resines, substances genantes pour l'analyse ulterieure. Les essais faits in vivo, ont mis en oeuvre des plants de tabac, qui permettent une nutrition par le petiole ou par la tige particulierement aisee.

    Connue au Maroc depuis la fin du XIX siècle, la leishmaniose cutanée (LC) constitue un problème de santé publique dans notre pays. Le but de notre travail est de décrire le profil épidémioclinique et l’évolution post thérapeutique chez les patients ayant une leishmaniose cutanée dans notre contexte. Nous avons effectué une étude rétrospective, basée sur l'exploitation des dossiers de malades ayant présenté une leishmaniose cutanée confirmée entre janvier 2003 et décembre 2012. Nous avons colligés 157 cas de leishmaniose cutanée. L’âge moyen des patients était de 34.5 ans avec des extrêmes de 6 ans à 63 ans. Le sex-ratio était de 2.34 H/F. La durée d’évolution moyenne des lésions était de 3,6 mois avec des extrêmes de 2 semaines à 10 mois. Les lésions étaient uniques dans 29.5% des cas. Les lésions siégeaient sur membres dans 63%. La forme ulcèro- croûteuse touchait plus de 48%. Le Glucantime était utilisé dans 29.3% des cas, l'azote liquide était utilisé chez 111 autres. L’évolution post-thérapeutique était favorable avec disparition quasi-complète des lésions dans un délai variant de 6 à 10 semaines, au prix de cicatrices inesthétiques chez 14 patients. La leishmaniose cutanée continue à poser un vrai problème de santé publique dans notre pays. L’émergence de formes sévères et résistantes à travers le monde doit inciter à multiplier et renforcer les mesures prophylactiques. PMID:25309671

    Summary Il s'agit d'une étude faisant ressortir les aspects épidémiologiques, cliniques et thérapeutiques des séquelles de brûlures du membre inférieur chez l'enfant, à propos de 42 cas colligés au service de chirurgie infantile de l'Hôpital Aristide Le Dantec (Sénégal). L'âge moyen retrouvé est de 5 ans et 3 mois, et le sex-ratio garçons/filles de 1,8/1. La brûlure thermique est causée par une flamme dans 33% des cas, par un liquide chaud dans 21% des cas, et par des braises dans 21% des cas. Les cicatrices rétractiles intéressent le genou et le creux poplité dans 47% des cas et le pied dans 45% des cas. Elles sont bilatérales dans 21% des cas, et concernent une autre localisation associée dans 21% des cas. Quant aux brides, 21% ont bénéficié d'une chirurgie, avec un délai moyen de 3 ans et 2 mois après la brûlure. Cette procédure chirurgicale consiste en une plastie en Z dans 91% des cas, à laquelle est associée une greffe de peau dans 54% des cas. Une rééducation fonctionnelle est pratiquée chez 54% des opérés. Parallèlement aux données de la littérature, nos résultats montrent que l'optimisation de la prise en charge passe par une meilleure prévention des accidents domestiques et une bonne codification thérapeutique.

    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.

    The International Radioecology Laboratory (IRL) located in Slavutych, Ukraine, was created in 1999 under the initiative of the United States Government and the Government of Ukraine in the framework of international cooperation on evaluation and minimization of consequences of the Chernobyl nuclear power plant (ChNPP) accident. Since the time the IRL was founded, it has participated in a large number of projects, including the following: 1) study of radionuclide accumulation, distribution, and migration in components of various ecological systems of the Chernobyl Exclusion Zone (ChEZ); 2) radiation dose assessments; 3) study of the effects of radiation influence on biological systems; 4) expert analysis of isotopic and quantitative composition of radioactive contaminants; 5) development of new methods and technologies intended for radioecological research; 6) evaluation of future developments and pathways for potential remediation of the ChEZ areas; 7) assistance in provision of physical protection systems for ionizing irradiation sources at Ukrainian enterprises; 8) reviews of open Russian language publications on issues associated with consequences of the ChNPP accident, radioactive waste management, radioecological monitoring, and ChNPP decommissioning; 9) conduct of training courses on problems of radioecology, radiation safety, radioecological characterization of test sites and environmental media, and research methods; 10) conduct of on-site scientific conferences and workshops on the ChEZ and radioecology problems; participation in off-site scientific conferences and meetings; and 11) preparation of scientific and popular science publications and interactions with mass media representatives. This article provides a brief overview of the major achievements resulting from this cooperation between the IRL and U.S. research centers.

    2006-07-01

    Full Text Available La question de la libert é e st récurrente dans les théories de l’habitus. Bien qu'il en fasse un concept central, elle reste si peu thématisée chez Bourdieu que de nombreux critiques ont pu taxer son travail de déterministe. Pourtant, une lecture approfondie permet de dégager au cœur du modèle au moins trois principes qui le rendent incompatible avec le déterminisme : la production d’un nombre infini de comportements à partir d’un nombre limité de principes, la mutation permanente et les limites intensives et extensives de l’appréhension sociologique. L’identification de ses principes et l’analyse de leur portée sur la matrice conceptuelle permettent de mieux comprendre le statut de la liberté dans l’œuvre de Bourdieu. The question of freedom is recurrent in the theories of habitus. In the Bourdieu’s work, the freedom plays an essential role but not often explicit. This article tries to identify and to analyse the underlying principles of the freedom in this sociological approach.

    Full text: We studied the cytogenetic effects in embryo tissue of gastropod snails and in root meristem of higher aquatic plants as chromosome aberration rate and reaction of snails on unfavorable condition of environment as change of structure, level of differentiation, death and cytogenetic stability of hemo lymph cell population. 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

    Full Text Available Cette recherche qualitative exploratoire vise à mettre à jour les impacts psychosociaux possibles de consommation de pornographie homosexuelle masculine à travers les discours de 20 usagers gais de Toronto (Canada. La consommation de pornographie semble plus acceptée et normalisée chez les hommes gais que chez les hommes hétérosexuels. Une telle consommation peut avoir une incidence sur certains aspects de la santé sexuelle et de la santé mentale. L'analyse thématique du corpus de nos données nous révèle que les impacts peuvent se faire sentir au niveau de l'apprentissage, de l'édification de la fantasmatique, de la validation de la sexualité entre hommes, de l'ingérence dans la vie sexuelle et enfin, sur l'habituation et sur l'image de soi/image corporelle. À l'aide de l’analyse critique de discours, nous avons pu documenter les discours sociaux plus larges en jeu dans les récits des usagers et voir de quelle façon ils se positionnent à l'intérieur de ces mêmes discours.

    This study analyzed the planning process (summer 2008 to fall 2009) of a Montreal project that offers housing and community follow-up to homeless people with mental disorders, with or without substance abuse disorders. With the help of the Advocacy Coalition Framework (ACF), advocacy groups that were able to navigate a complex intervention implementation process were identified. In all, 25 people involved in the Montreal At Home/Chez Soi project were surveyed through interviews (n=18) and a discussion group (n=7). Participant observations and documentation (minutes and correspondence) were also used for the analysis. The start-up phase of the At Home/Chez may be broken down into three separate periods qualified respectively as "honeymoon;" "clash of cultures;" and "acceptance & commitment". In each of the planning phases of the At Home/Chez Soi project in Montreal, at least two advocacy coalitions were in confrontation about their specific belief systems concerning solutions to address the recurring homelessness social problem, while a third, more moderate one contributed in rallying most key actors under specified secondary aspects. The study confirms the importance of policy brokers in achieving compromises acceptable to all advocacy coalitions. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Sea star (class Asteroidea, phylum Echinodermata) is one of the most successful marine organisms inhabiting a wide range of habitats. As one of the key stone species, sea stars are responsible for maintaining much of the local diversity of species within certain communities. Malaysian Exclusive Economic Zone (EEZ) Resource Survey had been carried out from 16th Aug to 6th Nov 2015 and one of the invertebrate by-catch organisms is sea star Stellaster childreni Gray, 1840. This study documents morphological characters and diet of the sea star, besides providing brief descriptions of the habitats based on particle size analysis and vessel log data sheet. A total of 217 individuals had been examined throughout this study. Fragments of flora and fauna were found in the gut including Mollusca (gastropod, bivalves, and scaphopods), sponge seagrass, and seaweed as well as benthic Foraminifera. Stellaster childreni were found at depth of 45 m to 185 m in the South China Sea off Sarawak Malaysia, with various sea bottom substrata. Approximately 41% of S. childreni were found at a mixture of sandy and muddy substratum, followed by mixture of sandy and coral (19.3%), muddy substratum (17.5%), coral substratum (11.5%), and sandy areas (10.6%). The widely distributed sea star on different types of sea beds suggested healthy deep sea ecosystem; thus Malaysia should explore further potential fisheries resources in the EEZ off Sarawak coast.

    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 quantitative approach used in this work may provide to stakeholders, scientists and fishers a

    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.

    Dans cette étude, nous avons comparé l’activité insulinosécrétoire des îlots de Langerhans isolés du rat Wistar et du rat des sables, afin de déterminer les variation interspécifiques. Nos résultats préliminaires indiquent que l'effet le plus probant est observé en présence de l’IL-1b. En effet, cette cytokine stimule la sécrétion d’insuline de manière dose-dépendante également chez le rat des sables; toutefois, l'amplitude de la réponse est plus prononcée chez le rongeur désertique, avec une augmentation du taux de l’insuline libérée de l’ordre de 147%, en présence d’une concentration de 20 UI/ml de l’IL-1b, comparée à la sécrétion basale. Quant à l’IL-2, nous n’avons enregistré aucune modification dans l’activité insulinosécrétoire des 2 espèces.

Méthodes C’était une étude cas-témoin des accouchées d’une grossesse monofoetale de Décembre 2013 à Mai 2014 dans 10 maternités de référence à Lubumbashi (RD Congo). Les adolescentes (adolescentes était de 7,7%. Nous avons observé que la césarienne (ORa=1,9 (1,1-3,1)), l’épisiotomie (ORa=4,2 (2,9-5,9)), la délivrance pathologique (ORa= 2,7 (1,1-6,5)), l’éclampsie (ORa= 4,4 (1,3-14,5)) et le faible poids de naissance (ORa=2,0 (1,3-3,0)) ont été significativement plus élevés chez les adolescentes que chez les adultes. Conclusion L’accouchement chez les adolescentes, comparativement à celui de femmes âgées de 20-34 ans, reste associé à un mauvais pronostic. D’où l’organisation des séances de sensibilisation pour une meilleure fréquentation des services consultations prénatales, une optimisation du dépistage, de la surveillance et de la prévention des pathologies de la grossesse chez les adolescentes s’avère importante et urgente. Introduction This study aimed to determine the frequency and to assess maternal and perinatal prognosis for vaginal delivery in adolescent girls in the city of Lubumbashi.

    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.

    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.

    Introduction En République Démocratique du Congo (RDC), plus d'un million de don de sang ont été réalisés entre 2007 et 2011. Cependant, aucun bilan portant sur la carence en fer et l'anémie ferriprive, conséquence d'un don de sang chez les donneurs de sang (DS), n'est disponible dans ce pays. L'objectif de cette étude était d'estimer la prévalence de la carence en fer, de l'anémie et de l'anémie ferriprive chezles DS au Centre National de Transfusion Sanguine (CNTS) à Kinshasa en RDC. Méthodes Entre Décembre 2012 et Août 2013, une étude transversale a été menée au CNTS où des DS éligibles au don de sang ont été inclus. Les informations socio démographiques et des prélèvements sanguins ont été collectés de manière simultanée au don de sang. La ferritine sérique a été dosée pour évaluer la carence en fer en utilisant la technique ELISA. L'hémogramme a été réalisé en vue d’évaluer et mettre au point l'anémie. Résultats Au total 386 DS ont été inclus dans cette étude. La prévalence de la carence en fer et de l'anémie ferriprive étaient respectivement de 63,2% (244/386) et 25,9% (100/386) des DS. Une anémie a été trouvée chez 36.5% (141/386) au moment du don de sang. Conclusion La carence en fer, l'anémie et l'anémie ferriprive demeurent très fréquentes chez les DS à Kinshasa. Ces résultats suggèrent la révision des tests biologiques utilisés dans le recrutement des DS au CNTS. Par ailleurs le dosage de la ferritine s'impose en routine chez les DS rég PMID:27303590

    Technical proposals are prepared to create a procedure for operative control of drilling works. Such a procedure will permit detecting the displacement of radioactively contaminated ground along borehole bore and correcting the drilling work procedure, which would prevent radioactive substance spreading, in boreholes of 'Ukryttya' object local zone and those of Exclusion Zone

    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

    The study characterised potential waste arisings in the Exclusion Zone surrounding the Chernobyl Nuclear Power Plant. Studied sites include the Industrial Zone outside the Sarcophagus, three engineered disposal sites (the so-called PZRO), non-engineered near surface trench dumps (PVLRO), contaminated soil and sites of ''unauthorized'' disposal within the Exclusion Zone. Analysis of the previous methodology used for waste characterisation and inventory estimates identified a number of errors. A new database was established, which contains the most up-to date information on radwaste in the Exclusion Zone. Based on the analysis of the available information and potential radiological consequences, a judgement was taken regarding the priority of waste retrieval. In a number of cases it is necessary to carry out risk assessment to ensure that in-situ disposal would satisfy the Ukrainian regulations. Assessments of waste stream volumes for subsequent incineration, encapsulation, storage and disposal in the planned near-surface facilities have been made. It is judged that throughput and capacity of the planned waste management facilities specified by OSAT is, in general, appropriate to the likely waste arisings. (author)

    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.

    Americium-241 was found to accumulate in soils and biological objects of the environment. 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. Special attention is devoted to the bioavailability of 241 Am to the plants Galium rivale, G. tinctorium, G. aparine, G. intermedium, Berteroa incana, Artemisia absinthium, A. vulgaris, Centaurea borysthenica, C. arenaria, Cirsium arvense, Succissa pratensis, Solidago virgaurea, Linaria vulgaris, Lepidium ruderale, Stenactis annua, Veronica maxima, Verbascum lychnitis, Euphorbia cyparissias, Genista tinctoria, Erigeron canadensis, Oenothera biennis, Betula pendula and Quercus robur, which were collected from the Chernobyl, Kopachi, and Yanov districts. 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

    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.

    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.

    Les intoxications aiguës par les pesticides organophosphorés (OP) au cours de la grossesse sont des événements rares, peu décrites dans la littérature. A travers cette étude rétrospective, nous rapportons les résultats de sept cas d’ingestion suicidaire d’OP chez des femmes enceintes. Cette intoxication était le plus souvent grave. En effet, cinq des sept parturientes avaient un Glasgow initial des cas elle était défavorable pour le fœtus (mort fœtal in utéro). Deux mécanismes peuvent expliquer ces complications fœtales. Le premier est l’hypoxie fœtale associée ou non à un état de choc qui peuvent se traduire au niveau du RCF par une tachycardie ou des décélérations et aboutir ainsi à un décès in utero. Le deuxième mécanisme est le passage de ces pesticides à travers la barrière placentaire, ce qui pose un risque potentiel pour le fœtus par altération des systèmes enzymatiques des microsomes.

    Individuals experiencing homelessness are particularly vulnerable to food insecurity. The At Home/Chez Soi study provides a unique opportunity to first examine baseline levels of food security among homeless individuals with mental illness and second to evaluate the effect of a Housing First (HF) intervention on food security in this population. At Home/Chez Soi was a 2-year randomized controlled trial comparing the effectiveness of HF compared with usual care among homeless adults with mental illness, stratified by level of need for mental health services (high or moderate). Logistic regressions tested baseline associations between food security (US Food Security Survey Module), study site, sociodemographic variables, duration of homelessness, alcohol/substance use, physical health and service utilization. Negative binomial regression determined the impact of the HF intervention on achieving levels of high or marginal food security over an 18-month follow-up period (6 to 24 months). Community settings at five Canadian sites (Moncton, Montreal, Toronto, Winnipeg and Vancouver). Homeless adults with mental illness (n 2148). Approximately 41 % of our sample reported high or marginal food security at baseline, but this figure varied with gender, age, mental health issues and substance use problems. High need participants who received HF were more likely to achieve marginal or high food security than those receiving usual care, but only at the Toronto and Moncton sites. Our large multi-site study demonstrated low levels of food security among homeless experiencing mental illness. HF showed promise for improving food security among participants with high levels of need for mental health services, with notable site differences.

    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.)

    A search for exclusive or semi-exclusive photon pair production, pp to p* + photon pair + p(*) (where p* stands for a diffractively-dissociated proton), and the observation of exclusive and semi-exclusive electron pair production, pp to p(*) + ee + p(*), in proton-proton collisions at $\\sqrt{s}$=7 TeV, are presented. The analysis is based on a data sample corresponding to an integrated luminosity of 36 inverse picobarns recorded by the CMS experiment at the LHC at low instantaneous luminosities. Candidate photon pair or electron pair events are selected by requiring the presence of two photons or a positron and an electron, each with transverse energy ET > 5.5 GeV and pseudorapidity abs(eta) < 2.5, and no other particles in the region abs(eta) < 5.2. No exclusive or semi-exclusive diphoton candidates are found in the data. An upper limit on the cross section for the reaction pp to p(*) + photon pair + p(*), within the above kinematic selections, is set at 1.18 pb at 95% confidence level. Seventeen exclu...

  4. Exclusive Dealing and Entry

    OpenAIRE

    João Leão

    2008-01-01

    This paper examines the use of exclusive dealing agreements to prevent the entry of rival firms. An exclusive dealing agreement is a contract between a buyer and a seller where the buyer commits to buy a good exclusively from the seller. One main concern of the literature is to explain how an incumbent seller is able to persuade the buyers to sign an exclusive dealing agreement that deters the entry of a more efficient rival seller. We propose a new explanation when the buyers are downstream ...

  5. Evaluation Of The Exclusion And Low Population Areas Around A Nuclear Power Plant

    International Nuclear Information System (INIS)

    Tawfik, F.S.

    2011-01-01

    Being adjacent to the nuclear power plant (NPP) the exclusion area (EA) is the area of greatest importance. It essentially defines a buffer zone where the public has no access. It helps to define the fenced plant area, the site area and the public area. Also, the low population area is the area immediately surrounding the exclusion area near a licensed reactor in terms of public safety and the ability of residents to get away from the plant in an emergency. This study clarifies their significance and reviews the international approach on them. Assuming the nuclear power plant site at the north coast of Egypt, the exclusion area and low population area are determined according to CFR (2002). In this method, a maximum possible amount of radioactivity release (called a source term) should be assumed. The boiling water reactor (BWR) with a power 1000 MW was used to carry the calculation and assuming a severe loss of coolant accident with meltdown of reactor. The site specific data have been collected, investigated and processed. The effect of the degree of atmospheric stability and building width of the plant were examined. The proceeding factors that control the determination of exclusion area and low population area should be taken into consideration in the site evaluation stage and design basis of NPP to set a minimum distances for them

  7. Social Exclusion Anxiety

    DEFF Research Database (Denmark)

    Søndergaard, Dorte Marie

    2017-01-01

    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...

    A search for exclusive or semi-exclusive photon pair production, pp to p(*) + photon pair + p(*) (where p(*) stands for a diffractively-dissociated proton), and the observation of exclusive and semi-exclusive electron pair production, pp to p(*) + ee + p(*), in proton-proton collisions at sqrt(s) = 7 TeV, are presented. The analysis is based on a data sample corresponding to an integrated luminosity of 36 inverse picobarns recorded by the CMS experiment at the LHC at low instantaneous luminosities. Candidate photon pair or electron pair events are selected by requiring the presence of two photons or a positron and an electron, each with transverse energy ET > 5.5 GeV and pseudorapidity abs(eta) < 2.5, and no other particles in the region abs(eta) < 5.2. No exclusive or semi-exclusive diphoton candidates are found in the data. An upper limit on the cross section for the reaction pp to p(*) + photon pair + p(*), within the above kinematic selections, is set at 1.18 pb at 95% confidence level. Seventeen exclusive or semi-exclusive dielectron candidates are observed, with an estimated background of 0.85 +/- 0.28 (stat.) events, in agreement with the QED-based prediction of 16.3 +/- 1.3 (syst.) events.

    Full Text Available Les IGF, leurs récepteurs et leurs protéines de liaison constituent une famille moléculaire qui joue un rôle essentiel dans la régulation de la croissance et du développement. Nous nous sommes intéressés à la caractérisation moléculaire de l'IGF-l et de son récepteur (IGF-1R chez le turbot (Psetta maxima, un poisson plat téléostéen. Par RT-PCR, nous avons clone un ADNc codant pour les quatre domaines de l'IGF-l mature. La protéine présente 70 à 96 % d'identité avec les autres IGF-I de vertébrés. Le clonage de la séquence codante entière du récepteur a nécessité la construction d'une banque d'ADNc d'embryons de turbots. Le récepteur est organisé en domaines dont la taille et les caractéristiques sont semblables à celles des autres récepteurs aux IGF de type 1 décrits chez les mammifères et le poulet. La région catalytique est particulièrement conservée. Dans certains domaines, notamment dans la région C-terminale du précurseur, quelques différences qui pourraient avoir une importance fonctionnelle sont cependant observées. Enfin, par RT-PCR, nous avons mis en évidence une régulation ontogénique du statut de polyadénylation des ARNm IGF-1R.

    L’asplénie, qu’elle soit fonctionnelle ou anatomique, s’associe à un accroissement du risque d’infection potentiellement fatale ou constituant un danger de septicémie postsplénectomie (SPS). En raison du risque accru de bactériémie par des bactéries encapsulées chez les enfants aspléniques, la vaccination visant à prévenir une infection au Streptococcus pneumoniae, à l’Haemophilus influenzae de type b (Hib) et au Neiserria meningitidis est recommandée. Malgré la prévalence croissante de S pneumoniae pénicillinorésistant, on recommande aussi l’usage de pénicilline prophylactique chez les enfants aspléniques de moins de cinq ans, et pendant au moins un an après une splénectomie. La poursuite de la prophylaxie antibiotique après cette période dépend de la situation clinique de chaque enfant et de la prévalence de S pneumoniae pénicillinorésistant au sein de la collectivité. Lorsque des enfants aspléniques font de la fièvre ou présentent des symptômes non spécifiques, ils devraient faire l’objet d’une évaluation immédiate. Si on présume la présence de septicémie bactérienne, il faut procéder à une analyse du sang et des autres liquides organiques pertinents et entreprendre sur-le-champ une antibiothérapie à large spectre par voie parentérale, laquelle doit agir également contre les souches de S pneumoniae présentes dans la collectivité. Chez les enfants aspléniques souffrant d’une septicémie foudroyante à S pneumoniae, le taux de mortalité est élevé, malgré l’utilisation rapide d’une antibiothérapie convenable, d’où l’importance des mesures préventives.

    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.

    Introduction Le strabisme est défini comme un syndrome à double composante: motrice et sensorielle. Le but de ce travail est de décrire les aspects épidémiologiques et cliniques du strabisme chez l'enfant congolais de 0 à 15 ans dans la ville de Lubumbashi. Méthodes Il s'agit d'une étude descriptive longitudinale sur les aspects épidémiologiques et cliniques du strabisme chez l'enfant congolais de 0 à 15 ans dans la ville de Lubumbashi entre Décembre 2012 à Décembre 2013. Nous avons recueilli l’âge des patients, leur sexe, leur provenance, le type de strabisme, la réfraction, le fond d'oeil, les antécédents (hérédité) ainsi que le type de la déviation strabique observé sur 70 patients. Résultats Nous avons observé 70 cas de strabisme manifeste dont 31 cas (44,28%) étaient dans la tranche d’âge comprise entre 0 et 5 ans. L’âge moyen de nos patients était de 6,7 ans avec une prédominance du sexe féminin, soit 51,42%. Le strabisme était convergent dans 65,71%, divergent dans 30%, et vertical dans 4,28%. Les ésotropies représentaient 65 cas (92,85%), quatre cas (5,71%) avaient un antécédent familial de strabisme au premier degré de parenté, 21 cas (30%) au second degré de parenté, 45 cas (64,28%) n'avaient pas cet antécédent. L'oeil gauche était le plus dominé dans 30% des cas. Les facteurs favorisant le strabisme étaient inconnus dans 54 cas (77,14%). Le strabisme était secondaire à l'hypermétropie chez 32 patients (42,71%). Conclusion La fréquence du strabisme dans la ville de Lubumbashi chez les enfants âgés de 0 à 15 ans est de 0,50%. Comme dans la plupart des études sur le strabisme de l'enfant, c'est l’ésotropie qui est la déviation la plus commune. PMID:26834919

    Full Text Available Le comportement alimentaire, indispensable à la survie de l'individu et donc de l'espèce, occupe à ce titre une position de première importance dans la hiérarchie des comportements fondamentaux qui tous en dépendent très étroitement. Chez les poissons, cette prééminence se trouve illustrée par l'extrême diversité des supports sensoriels impliqués et des expressions comportementales qui leur sont liées. A la suite d'un certain nombre de mises en évidence neurophysiologiques et éthologiques de l'importance du sens chimique (olfaction, gustation dans le comportement alimentaire des poissons, de très importants secteurs d'études électrophysiologiques et d'analyses physico-chimiques visant à en déterminer la nature exacte (en termes de substances actives se sont développés ces vingt dernières années. De tous ces travaux dont les plus avancés sont présentés ici, il ressort que les acides aminés de série L plus ou moins associés à d'autres composés de poids moléculaires < 1000 constituent des composés chimiques jouant un rôle déterminant dans le comportement alimentaire de nombreuses espèces de poissons carnivores.

    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.

  2. Origin of microbial life hypothesis: a gel cytoplasm lacking a bilayer membrane, with infrared radiation producing exclusion zone (EZ) water, hydrogen as an energy source and thermosynthesis for bioenergetics.

    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.

    Full Text Available L'évolution quantitative et qualitative de la production de sperme au cours de la période de spermiation a été étudiée chez des brochets maintenus en captivité dans un étang de 400 m2. Le sperme est prélevé toutes les semaines à partir du début de février, et pendant près de 2 mois. La quantité de sperme recueillie est très faible et présente de fortes variations individuelles ; elle augmente progressivement jusqu'à la 5me semaine et décroit ensuite. La quantité moyenne de sperme récoltée par mâle est de l'ordre de 0,7 ml/semaine et varie considérablement d'un mâle à l'autre (0.07 à 1,5 ml. La concentration du sperme en spermatozoïdes varie entre 18 et 25 milliards par ml ( X = 21,5 109 + 2,11. La quantité de spermatozoïdes récoltée par semaine est de 28,5 106 + 26,4/kg de poids corporel. La qualité du sperme appréciée par l'intensité et la durée de motilité suit une évolution similaire à celle de la quantité de sperme récoltée avec des valeurs maximales à 4 semaines et minimales en début et fin de période de prélèvement. Les premières ovulations détectées sur des femelles stockées dans les mêmes conditions que les mâles ont été observées à la 6me semaine de prélèvements alors que les performances de spermiation avaient déjà fortement déclinées. Il est vraisemblable que les conditions expérimentales particulièrement traumatisantes pour les mâles ont affecté prématurément la spermiation, amplifiant ainsi le décalage fréquemment observé entre les périodes de spermiation et d'ovulation.

Par définition, un écrivain francophone c’est celui qui écrit en français peut-on dire de manière tautologique. Mais cette définition passe sous silence la dimension institutionnelle voire idéologique à l’œuvre dans la constitution de tout groupe social. Ainsi, selon Dominique Combe, les écrivains francophones forment un groupe bien distinct dans lequel des hommes et des femmes « expriment le sentiment d’appartenir, à travers la langue française, à une communauté de pensée, de culture. » (Combe, 1995 :14.

    While literature describing immigrant's breastfeeding practices exists, especially among those living within developed countries, there is a significant gap in knowledge on how the host culture may influence the EBF behaviors of refugees, especially those living in protracted situations within sub-Saharan Africa. A cross-sectional study was conducted in the Buduburam Refugee Settlement in Ghana from July-August 2008 to explore the association between the amount of time living in Ghana and exclusive breastfeeding practices among Liberian refugees and Ghanaians in surround villages. The study included 480 women: 239 Liberians living in 12 settlement zones (in two of which Liberians and Ghanaians co-exist), 121 Ghanaians living in two settlement zones, and 120 Ghanaians living in nearby urban village of Awutu. Liberian mothers who lived in Ghana at least eight years were significantly more likely to exclusively breastfeed (OR: 1.78, 95% CI: 1.02, 3.09) compared to Ghanaian mothers living in Awutu. These findings suggest that increased time living in Buduburam improved the chances of EBF success among Liberians, perhaps as a result of unique EBF education/support opportunities offered in the settlement to Liberian refugees that were not readily available to Ghanaians. Further research to understand the "mechanisms" explaining exclusive breastfeeding differences as a function of time spent in host country is needed for improving breastfeeding support in refugee settlements and host communities. © 2016 John Wiley & Sons Ltd.

    2001-01-01

    The purpose of the Saturated Zone Colloid-Facilitated Transport Analysis and Modeling Report (AMR), as outlined in its Work Direction and Planning Document (CRWMS MandO 1999a), is to provide retardation factors for colloids with irreversibly-attached radionuclides, such as plutonium, in the saturated zone (SZ) between their point of entrance from the unsaturated zone (UZ) and downgradient compliance points. Although it is not exclusive to any particular radionuclide release scenario, this AMR especially addresses those scenarios pertaining to evidence from waste degradation experiments, which indicate that plutonium and perhaps other radionuclides may be irreversibly attached to colloids. This report establishes the requirements and elements of the design of a methodology for calculating colloid transport in the saturated zone at Yucca Mountain. In previous Total Systems Performance Assessment (TSPA) analyses, radionuclide-bearing colloids were assumed to be unretarded in their migration. Field experiments in fractured tuff at Yucca Mountain and in porous media at other sites indicate that colloids may, in fact, experience retardation relative to the mean pore-water velocity, suggesting that contaminants associated with colloids should also experience some retardation. Therefore, this analysis incorporates field data where available and a theoretical framework when site-specific data are not available for estimating plausible ranges of retardation factors in both saturated fractured tuff and saturated alluvium. The distribution of retardation factors for tuff and alluvium are developed in a form consistent with the Performance Assessment (PA) analysis framework for simulating radionuclide transport in the saturated zone. To improve on the work performed so far for the saturated-zone flow and transport modeling, concerted effort has been made in quantifying colloid retardation factors in both fractured tuff and alluvium. The fractured tuff analysis used recent data

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.

    Introduction La démence peut retentir lourdement sur les aidants familiaux du patient. Les objectifs de notre étude étaient de déterminer le niveau de fardeau et de la dépression chez les aidants familiaux de sujets déments, et d'identifier les facteurs associés à un niveau de fardeau élevé. Méthodes Il s'agissait d'une enquête auprès de 65 aidants tunisiens. Les niveaux de fardeau et de la dépression ont été évalués par, respectivement, l'inventaire de Zarit et l’échelle de Beck. Résultats Le taux des aidants qui avaient un niveau de fardeau élevé était de 52,3 %. Une dépression modérée ou sévère a été relevée chez 46,2 %. Un niveau de fardeau élevé était corrélé, du côté de l'aidant, avec le niveau socio-économique moyen à élevé, la cohabitation avec le patient, le fait d’être son conjoint, la réduction des activités quotidiennes et la sévérité de la dépression, et, du côté du dément, avec l'agressivité. Conclusion Les facteurs corrélés à un niveau de fardeau élevé orientent vers les cibles d'intervention et sont susceptibles d’être améliorés par la prise en charge, ce qui contribuerait à alléger la détresse des aidants.

  12. L’amor humanus chez Marsile Ficin

    2010-12-01

    Full Text Available Les éditions et études du Commentaire sur le Banquet de Platon, ou De amore, de Marsile Ficin ont mis en évidence que la conception de Vamor humanus chez l'humaniste florentin, inspirée certes des définitions du Banquet de Platon, était étroitement liée aux conceptions néoplatoniciennes héritées de Plotin. Néanmoins, l'interprétation du texte de Platon et les développements de ses successeurs ne sauraient à eux seuls rendre compte de la définition ficinienne, notamment dans son lien avec la notion, romaine, de la fascinatio. La philosophie et la poésie romaines des passions offrent une analyse du sentiment amoureux dont les échos sont sensibles dans le texte même du Commentaire. En effet, l'exposé des passions qu'offre le livre IV des Tusculanes a sans aucun doute fourni à Ficin les caractéristiques et la définition du « mauvais amour », dont l'évocation n'est pas étrangère aux motifs poétiques tels qu'on peut les trouver, par exemple, dans la poésie ovidienne à propos du mythe de Narcisse, dont Ficin se souvient. Si Cicéron soulignait, au début du livre IV des Tusculanes, la tension qui existait entre l'anthropologie platonicienne et la théorie des passions stoïcienne, il ne la résolvait pas. Ficin, lui, réalise cette articulation grâce à la hiérarchisation néoplatonicienne des différents amours et peut ainsi affirmer l'existence d'un bon amour. Mais un tel amor humanus, qui est amour philopédique, destiné à l'élévation divine ou voué à s'affaisser jusqu'à la concupiscence bestiale, ne peut être qu'un moment dans le processus proposé par Ficin, un point de fragile équilibre, intenable.

    Full Text Available Les stratégies de restriction de la participation politique adoptées par les états ibéro-américains lors de leur indépendance ont fait que l'exil était utilisé comme un privilège réservé surtout à des gens de l'élite ayant subi l'ostracisme auprès de leurs réseaux d'appui. Entre la fin du XIXe siècle et le début du XXe, a eu lieu un processus de "massification" de l'exil atteignant un nombre croissant d'individus de classes sociales variées, conséquence de leur participation à la politique et à la sphère publique. Leur exclusion croissante des institutions a amené l'apparition de réseaux de solidarité et attiré l'attention de la sphère publique internationale sur les politiques des états d'origine. De vieux thèmes de politique interne ont rencontré un écho transnational et pris appui sur un souci grandissant concernant les ateintes aux droits de l'homme et les persécutions politiques. Ces mécanismes ont provoqué une transformation radicale de la structure, de l'impact et de la fonction de l'exil politique chez les états ibéroaméricains.

Avant de pouvoir être utilisés chez les humains, ces radiotraceurs doivent être caractérisés chez les petits animaux, principalement les rats et les souris. Pour cela, de nombreux échantillons sanguins doivent être prélevés et analysés (mesure de radioactivité, séparation de plasma, séparation d'espèces chimiques), ce qui représente un défi majeur chez les rongeurs à cause de leur très faible volume sanguin (˜1,4 ml pour une souris). Des solutions fournissant une analyse partielle sont présentées dans la littérature, mais aucune ne permet d'effectuer toutes les opérations dans un même système. Les présents travaux de recherche s'insèrent dans le contexte global d'un projet visant à développer un système microfluidique d'analyse sanguine complète en temps réel pour la caractérisation des nouveaux radiotraceurs TEP et TEM. Un cahier des charges a tout d'abord été établi et a permis de fixer des critères quantitatifs et qualitatifs à respecter pour chacune des fonctions de la puce. La fonction de détection microfluidique a ensuite été développée. Un état de l'art des travaux ayant déjà combiné la microfluidique et la détection de radioactivité a permis de souligner qu'aucune solution existante ne répondait aux critères du projet. Parmi les différentes technologies disponibles, des microcanaux en résine KMPR fabriqués sur des détecteurs semiconducteurs de type p-i-n ont été identifiés comme une solution technologique pour le projet. Des détecteurs p-i-n ont ensuite été fabriqués en utilisant un procédé standard. Les performances encourageantes obtenues ont mené à initier un projet de ma

    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).

    Résumé Objectif Effectuer une révision systématique des effets de repas en famille fréquents sur les résultats psychosociaux chez les enfants et les adolescents et examiner s’il existe des différences dans les résultats selon le sexe. Sources des données Des études ont été cernées à la suite d’une recherche dans MEDLINE (de 1948 à la dernière semaine de juin 2011) et dans PsycINFO (de 1806 à la première semaine de juillet 2011) à l’aide de l’interface Ovide. Les expressions et mots clés MeSH utilisés seuls ou en combinaisons étaient les suivants : family, meal, food intake, nutrition, diets, body weight, adolescent attitudes, eating behaviour, feeding behaviour et eating disorders. Les bibliographies des articles jugés pertinents ont aussi été passées en revus. Sélection des études La recherche initiale a produit 1783 articles. Pour être incluses dans l’analyse, les études devaient répondre aux critères suivants : être publiées en anglais dans une revue révisée par des pairs; porter sur des enfants ou des adolescents; traiter de l’influence des repas en famille sur les paramètres psychosociaux (p. ex. consommation de drogues et autres substances, troubles de l’alimentation, dépression) chez les enfants ou les adolescents; avoir une conception d’étude appropriée, notamment des méthodes statistiques acceptables pour l’analyse des paramètres. Quatorze articles satisfaisaient aux critères d’inclusion. Deux examinateurs indépendants ont étudié et analysé les articles. Synthèse Dans l’ensemble, les résultats font valoir que la fréquence des repas en famille est inversement proportionnelle aux troubles de l’alimentation, à la consommation d’alcool et de drogues, aux comportements violents, aux sentiments de dépression ou aux pensées suicidaires chez les adolescents. Il existe une relation positive entre de fréquents repas en famille, une bonne estime de soi et la réussite scolaire. Les

    Introduction La littérature scientifique dispose de très peu de données relatives à l’épidémiologie du VIH chez les sujets âgés en Afrique subsaharienne. Au Cameroun, les caractéristiques épidémiologiques de l'infection par le VIH chez les sujets âgés de 50 ans et plus ne sont pas documentées. Méthodes Dans une étude de cohorte rétrospective et une enquête transversale, nous avons comparé les caractéristiques clinico-biologiques et la survie post thérapeutique des patients âgés de 50 ans et plus, sous traitement antirétroviral au Centre de Traitement Agrée de Bafoussam - Cameroun, aux adultes plus jeunes. Résultats L’âge moyen était de 39 ans, les extrêmes étant 17 et 88 ans. Les sujets âgés de 50 ans et plus représentaient 14,1% des cas. Les plus âgés étaient moins bien informés sur les modes de transmission du virus (p = 0,04). Leur séropositivité au VIH était le plus souvent découverte au décours d'une infection opportuniste (p = 0,02). La fréquence de comorbidité était significativement plus élevée chez les personnes âgées de 50 ans et plus (p VIH. La promotion du dépistage et les programmes d’éducation sanitaire relatifs au VIH/SIDA devraient être renforcés au sein de cette communauté déjà affaiblie par le poids de l’âge, afin de réduire l'incidence du SIDA et de leur assurer prise en charge précoce.

    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.

    Introduction L'infection au VIH chez les nouveau-nés par leur mère peut être réduite grâce à des programmes de prévention de transmission mère-enfant du VIH (PTME). L'objectif dans cette étude était d’évaluer le traitement antirétroviral chez les femmes enceintes VIH-1 positif sur la transmission mère-enfant de l'infection au Centre Médical Saint Camille de Ouagadougou, Burkina Faso. Méthodes Des échantillons de spot de sang total ont été collectés chez 160 enfants âgés de 6 semaines, nés de mères VIH-1 positif et chez 40 enfants âgés de 2 à 13 mois provenant d'orphelinats et dont les mères étaient inconnues. Ces échantillons ont été testés avec le kit Abbott Real Time HIV-1 Qualitative. Un questionnaire a permis de connaitre les âges et les fonctions des femmes enceintes. Résultats Les femmes enceintes avaient un âge moyen global de 29,50±5,19 ans. Au total, 50,5% (101/200) ont été mises sous combinaison AZT/3TC/NVP et 29,5% (59/200) étaient sous prophylaxie (AZT/3TC). Le taux de transmission verticale du VIH-1 était de 0,0% (0/160) (p VIH-1 de la mère à l'enfant. De plus, le dépistage par PCR, des enfants orphelins infectés verticalement par le VIH, permet leur prise en charge thérapeutique précoce. PMID:26301003

    Precipitation zone systems exists for Mexico based on seasonality, quantity of precipitation, climates and geographical divisions, but none are convenient for the study of the relation of precipitation with phenomena such as El nino. An empirical set of seven exclusively Mexican and six shared zones was derived from three series of Standardized Precipitation Index (SPI) images, from 1940 through 1989: a whole year series (SPI-12) of 582 monthly images, a six month series (SPI-6) of 50 images for winter months (November through April), and a six month series (SPI-6) of 50 images for summer months (May through October). By examination of principal component and unsupervised classification images, it was found that all three series had similar zones. A set of basic training fields chosen from the principal component images was used to classify all three series. The resulting thirteen zones, presented in this article, were found to be approximately similar, varying principally at zones edges. A set of simple zones defined by just a few vertices can be used for practical operations. In general the SPI zones are homogeneous, with almost no mixture of zones and few outliers of one zone in the area of others. They are compared with a previously published map of climatic regions. Potential applications for SPI zones are discussed. [Spanish] Existen varios sistemas de zonificacion de Mexico basados en la estacionalidad, cantidad de precipitacion, climas y divisiones geograficas, pero ninguno es conveniente para el estudio de la relacion de la precipitacion con fenomenos tales como El Nino.

    Full Text Available Background:This study examines the effect of exclusive versus non-exclusive breastfeeding on specific infant morbidities from birth to nine months, in Conakry (Guinea. Methods:A cross-sectional study was conducted on 1,167 mother-infant pairs who visited one of 20 immunization centres in Conakry for vaccination between the 45th and 270th days of the child’s life. Two data sources were used: the infant health book and an orally administered questionnaire completed with the mother. Data analyses included univariate cross-tabulations and multivariate logistic regression models to estimate the effect of breastfeeding on infant morbidity. Results:Exclusive breastfeeding decreased with the infant’s age. At six months of age, the proportion of infants who were exclusively breastfed was only 15.5%. After adjusting for the infant’s age, and the interaction between the type of breastfeeding and the infant’s age, exclusive breastfeeding significantly protected the infants against many of the studied morbidities (OR: 0.28, CI: 0.15-0.51 and specifically against diarrhoea (OR: 0.38; 95% CI: 0.17 – 0.86, respiratory infections (OR: 0.27; 95% CI: 0.14 – 0.50, and low growth rate (OR: 0.11; 95% CI: 0.02 – 0.46, but not for otitis, urinary infection, or meningitis. Conclusion:This investigation confirmed the protective effects of exclusive breastfeeding on some specific infant’s morbidities during the first nine months of life. The results of this study are of great importance for the development of an information program designed to encourage the exclusive breastfeeding among the mothers of Conakry, Guinea.

    L’obectif était de mettre en relief les particularités du cancer de la thyroïde chez l’enfant et l’adolescent, et d’évaluer nos résultats par rapport à la littérature internationale a travers une série de cas la plus représentatif au Maroc: 22 cas. C'est une étude rétrospective descriptive des patients atteints de cancer différencié de la thyroïde, hospitalisés au service d’ORL et de Chirurgie Cervico-faciale de L’hopital 20 Août de Casablanca-Maroc, sur la période qui s’étend de Janvier 1995 à Mars 2015. Nous avons recueilli les données relatives à 22 cas, qui répondaient à nos critères d’inclusion. L’âge moyen de nos patients était de 14 ans, avec une sex-ratio 3,4, la plupart de nos patients ont consulté pour un nodule thyroïdien, associé dans 22,7% des cas à une adénopathie cervicale, et dans 9,1% à des signes de compression. L’ensemble des patients ont bénéficié d’une thyroïdectomie totale, suivie d’un curage ganglionnaire dans 31,82%. Le diagnostic de cancer thyroïdien a reposé sur l’examen anatomopathologique de la pièce opératoire, qui a objectivé un carcinome papillaire dans 95,4% des cas, et un carcinome vésiculaire dans 4,5%. Le traitement par l’iode radioactif 131 a été réalisé dans 100% des cas. Par la suite tous nos patients ont été mis sous hormonothérapie thyroïdienne. Une surveillance étroite et régulière a permis de détecter des métastases ganglionnaires chez 3 patients, et les métastases à distance chez 4 patients. Le cancer différencié de la thyroïde de l’enfant et l’adolescent est une entité rare mais agressive, son traitement se base sur la chirurgie, associée à l’irathérapie donnant un pronostic excellent.

Les résultats mettent en évidence que ce phénomène touche de manière asymétrique les jeunes hommes, tandis que chez les femmes les taux moyens sont les plus bas. L’analyse dans l’espace a souligné qu’il existe des zones avec des taux d’homicide élevés et stabilisés dans le temps, comme les régions métropolitaines de Rio de Janeiro et Vitória. En revanche, l’étude a montré qu’entre les régions métropolitaines de Belo Horizonte (RMBH, Campinas et San Paolo, les dynamiques sont différentes. This study is based on a geographical perspective and explores the spatial and temporal evolution of average homicide rates in Southeast Brazil, between 2001 and 2008 for different subpopulations (male, female, youth, and total population. Results show that this phenomenon affects asymmetrically young males, while women have the lowest average rates. Spatial analysis pinpoints consolidated areas with high homicide rates, such as the metropolitan areas of Rio de Janeiro and Vitoria. On the other hand, different dynamics can be observed among the metropolitan areas of Belo Horizonte (BHMA, Campinas and Sao Paulo.

Cet article vise principalement à évaluer l’efficacité et les scores de risque de CANRISK (Questionnaire canadien sur le risque de diabète, un outil de dépistage du diabète destiné aux Canadiens de 40 ans et plus pour détecter la dysglycémie chez les participants issus des Premières Nations et d’origine métisse en incluant les moins de 40 ans. L’objectif secondaire de cette étude est de déterminer si une modification des seuils relatifs au tour de taille (TT et à l’indice de masse corporelle (IMC améliore la valeur prédictive de modèles de régression logistique lorsque les variables du questionnaire CANRISK sont utilisées pour prédire la dysglycémie. Méthodologie : Nous avons recueilli auprès de 1479 participants métis et des Premières Nations des données provenant d’un questionnaire CANRISK autoadministré, de mesures anthropométriques et de résultats d’épreuve standard d’hyperglycémie provoquée par voie orale (HGPO. Nous avons calculé la sensibilité et la spécificité des scores CANRISK en appliquant les seuils usuels de classification des risques. Une régression logistique a été effectuée en utilisant des seuils tenant compte de l’origine ethnique pour l’IMC et le TT pour prédire la dysglycémie à l’aide des variables CANRISK. Résultats : Appliqué aux résultats de l’épreuve d’HGPO, le score seuil CANRISK à 33 points a conduit à une sensibilité et une spécificité de l’outil CANRISK de respectivement 68 % et 63 % chez les 40 ans et plus, et de respectivement 27 % et 87 % chez les moins de 40 ans. L’utilisation d’un seuil inférieur, à 21 points, a fait monter à 77 % la sensibilité chez les moins de 40 ans, avec une spécificité de 44 %. Malgré la faible spécificité correspondant à ce

    Full Text Available La sélection de l'habitat analysée à partir d'un ensemble de données récoltées sur des cours d'eau hétérogènes du point de vue spatio-temporel doit être interprétée en fonction du site et de l'échelle d'étude. La microniche spatiale fondamentale du juvénile de saumon Atlantique et de truite commune est caractérisée en été par une forte préférence pour une faible valeur de la vitesse de courant focale en raison d'une stratégie de gain énergétique basée essentiellement sur une prise alimentaire de la faune dérivante qui permet de maximiser les comportements de prise de position et d'attente du poisson. Cette microniche est également dépendante de la taille : chez le saumon, les plus gros parrs sont tolérants ; par contre chez la truite, une préférence accrue pour les habitats profonds est observée lorsqu'elles grossissent. La niche effective de la truite est relativement plus structurée par des valeurs élevées de la profondeur d'eau et des valeurs faibles de vitesse de courant lorsqu'elle est comparée à celle du saumon caractérisée par de faibles hauteurs d'eau et par des vitesses de courant élevées. Ces différences proviennent d'une plus grande tolérance du saumon pour les fortes vitesses de courant, combinée à un déplacement de la niche de cette espèce par suite d'une compétition avec la truite qui est plus agressive. Cette compétition interactive et interspécifique aboutit à une réduction de la niche spatiale effective chez le Saumon lorsque les paramètres vitesse de courant et profondeur d'eau sont pris en compte simultanément, et pas chez la truite.

  17. Frequencies of micronuclei in bank voles from zones of high radiation at Chernobyl, Ukraine

    A population of Clethrionomys glareolus (bank vole) from a highly radioactive area within the Chernobyl, Ukraine exclusion zone was sampled in June 1997 and in June and October 1998. Internal radiation doses from radiocesium were estimated to be as high as 8 rads/d. Total dose, which takes into account the internal dose form radiostrontium and the surrounding environment, was estimated to be 15 to 20 rads/d. In contrast, individuals from a reference population lying outside of the exclusion zone registered negligible levels of contamination. The authors used the micronucleus test in a double-blind study to analyze blood samples from 58 individuals. They scored more than 600,000 polychromatic erythrocytes (PCEs) but could not reject the null hypothesis that the frequency of micronucleated PCEs in voles exposed to radiation was equal to the frequency in unexposed voles. Results of their study stand in sharp contrast to earlier reports of increased frequencies of micronuclei in rodents exposed to fallout of the Chernobyl accident, but with radiation doses that were orders of magnitude lower than those reported here. Radio resistance and experimental methods are possible explanations for these differences in the results.

    The diagnosis of nodal marginal zone lymphoma is one of the remaining problem areas in hematopathology. Because no established positive markers exist for this lymphoma, it is frequently a diagnosis of exclusion, making distinction from other low-grade B-cell lymphomas difficult or even impossible. This systematic review summarizes and discusses the current knowledge on nodal marginal zone lymphoma, including clinical features, epidemiology and etiology, histology, and cytogenetic and molecular features. In particular, recent advances in diagnostics and pathogenesis are discussed. New immunohistochemical markers have become available that could be used as positive markers for nodal marginal zone lymphoma. These markers could be used to ensure more homogeneous study groups in future research. Also, recent gene expression studies and studies describing specific gene mutations have provided clues to the pathogenesis of nodal marginal zone lymphoma, suggesting deregulation of the nuclear factor kappa B pathway. Nevertheless, nodal marginal zone lymphoma remains an enigmatic entity, requiring further study to define its pathogenesis to allow an accurate diagnosis and tailored treatment. However, recent data indicate that it is not related to splenic or extranodal lymphoma, and that it is also not related to lymphoplasmacytic lymphoma. Thus, even though the diagnosis is not always easy, it is clearly a separate entity. PMID:23813646

    Full Text Available Social exclusion is an interactive process between multiple people, yet previous research has focused almost solely on the negative impacts on targets. What advice is there for people on the other side (i.e., sources who want to minimize its negative impact and preserve their own reputation? To provide an impetus for research on the interactive nature of exclusion, we propose the Responsive Theory of Social Exclusion. Our theory postulates that targets and sources’ needs are better maintained if sources use clear, explicit verbal communication. We propose that sources have three options: explicit rejection (clearly stating no, ostracism (ignoring, and ambiguous rejection (being unclear. Drawing on psychology, sociology, communications, and business research, we propose that when sources use explicit rejection, targets’ feelings will be less hurt, their needs will be better protected, and sources will experience less backlash and emotional toil than if sources use ambiguous rejection or ostracism. Finally, we propose how the language of rejections may impact both parties.

    Introduction La co-infection avec l'hépatite B est l'un des défis majeurs de la prise en charge du VIH depuis l'amélioration de l'accès aux antirétroviraux en Afrique. La présente étude visait à estimer la prévalence de l'hépatite B chez les personnes séropositives au VIH à Parakou et décrire les facteurs associés. Méthodes Il s'agit d'une étude transversale menée de Mai 2011 à Juin 2012 dans le service de Médecine du CHU de Parakou. Ont été inclus tous les adultes séropositifs au VIH vus en consultation ou hospitalisés. Les données ont été collectées par interviews et dépouillement de dossiers médicaux. L'antigène HBs a été recherché par un test rapide et l'ALAT a été dosé. L'analyse des données a été faite avec le logiciel EpiInfo 3.5.1. Les proportions ont été comparées grâce au test de Chi-deux ou au test de Fisher au seuil de significativité de 5%. Un modèle de régression logistique multivariable a permis d'expliquer la prévalence de l'hépatite B. Résultats Sur les 744 sujets inclus on a dénombré 555 femmes. L’âge moyen était de 35,5 + 10,1 ans. La prévalence de l'hépatite B a été estimée à 16,9% (IC95: 14,3%-19,9%). Cette prévalence était plus élevée chez les sujets originaires du Borgou/Alibori et ceux au stade 4 de l'OMS. Conclusion La prévalence de la co-infection VIH/VHB au CHU Parakou est élevée. Le dispositif national de prise en charge et de prévention de l'hépatite B chez les personnes séropositives au VIH doit être renforcé. PMID:26097629

    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

    2015-12-01

    Full Text Available L’autofiction chez Nelly Arcan, en plus de mettre en scène l’union atypique, bien que déjà vue, de l’écriture et de la prostitution, donne l’impression d’être tout entier un rassemblement de pensées opposées, incompatibles, en désordre. S’opposer à soi-même peut montrer l’existence d’un esprit critique, en plus de la capacité à pousser celui-ci au-delà du simple débat entre amis. La critique négative et la négativité de la critique pénètrent profondément le processus d’écriture dans les autofictions d’Arcan, Putain et Folle, et cette dernière possède définitivement un esprit critique. Par contre, celui-ci ne semble pas la source des oppositions qui caractérisent sa plume. La poétique de l’auteure semble en effet être fondée sur l’utilisation constante d’une série de contradictions. C’est dans la tension de l’exploration de ces contradictions, de la force de cette dialectique négative, qu’Arcan tente de faire éclater le sens des préjugés, de ce qui a été jugé d’avance sans aucun esprit critique, afin d’atteindre une conception et une compréhension qui seraient plus authentiques.

    Chernobyl alienated zone (ChAZ) at present and in the visible future, being potentially dangerous territory for the inhabitants of Ukraine, still more or less actively utilized for industrial needs, and represents itself the unique polygon for the accomplishment of the complex diverse investigations aiming at the studies in different media of the processes and regularities, caused by the nuclear accident and by cessation of the intense economical utilization of the territory, as well as at the development of various measures concerning rehabilitation of different objects, areas, biosphere and a man himself. The maps are one of the most effective and systematically organized methods of depicting accumulated knowledge about the structure and processes in separate media. The complex cartographic analysis of these consequences could be properly accomplished only on the basis of revealing and regarding the environmental elements structure regularities and processes intrinsic for them and for the medium as a whole

    Kovesi, Tom; Giles, Brenda Louise; Pasterkamp, Hans

    L’asthme est un grave problème de santé pour les enfants inuits et des Premières nations. Chez les enfants de moins d’un an, il faut distinguer l’asthme de la bronchiolite virale, anormalement fréquente chez les enfants autochtones du Canada. Chez les enfants de moins de six ans, le diagnostic dépend de la présence de symptômes classiques, de l’absence de caractéristiques atypiques et de la consignation de la réponse au traitement, notamment la réponse rapide et transitoire aux bronchodilatateurs. Chez les enfants plus âgés, il faut, dans la mesure du possible, déterminer la présence d’une obstruction réversible des voies aériennes par spirométrie afin de confirmer le diagnostic, ainsi qu’évaluer et corriger les déclencheurs environnementaux. L’utilisation régulière de corticoïdes en aérosol est la principale mesure à prendre pour maintenir un bon contrôle de l’asthme chez les enfants asthmatiques. Les clients et leur famille devraient recevoir une formation sur l’asthme. Il faut réévaluer régulièrement le contrôle aux visites de suivi dans des centres de santé et rajuster le traitement à la dose la plus basse possible pour le maintien de ce contrôle.

  12. Impact of radionuclide spatial variability on groundwater quality downstream from a shallow waste burial in the Chernobyl Exclusion Zone

    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

  13. The N-terminal cleavage of chondromodulin-I in growth-plate cartilage at the hypertrophic and calcified zones during bone development.

    Directory of Open Access Journals (Sweden)

    Shigenori Miura

    Full Text Available Chondromodulin-I (ChM-I is a 20-25 kDa anti-angiogenic glycoprotein in cartilage matrix. In the present study, we identified a novel 14-kDa species of ChM-I by immunoblotting, and purified it by immunoprecipitation with a newly raised monoclonal antibody against ChM-I. The N-terminal amino acid sequencing indicated that it was an N-terminal truncated form of ChM-I generated by the proteolytic cleavage at Asp37-Asp38. This 14-kDa ChM-I was shown by the modified Boyden chamber assay to have very little inhibitory activity on the VEGF-A-induced migration of vascular endothelial cells in contrast to the intact 20-25 kDa form of ChM-I (ID50 = 8 nM. Immunohistochemistry suggested that 20-25 kDa ChM-I was exclusively localized in the avascular zones, i.e. the resting, proliferating, and prehypertrophic zones, of the cartilaginous molds of developing long bone, whereas the 14-kDa form of ChM-I was found in hypertrophic and calcified zones. Immunoblotting demonstrated that mature growth-plate chondrocytes isolated from rat costal cartilage actively secrete ChM-I almost exclusively as the intact 20-25 kDa form into the medium in primary culture. Taken together, our results suggest that intact 20-25 kDa ChM-I is stored as a component of extracellular matrix in the avascular cartilage zones, but it is inactivated by a single N-terminal proteolytic cleavage in the hypertrophic zone of growth-plate cartilage.

  16. Abnormal neural responses to social exclusion in schizophrenia.

    Directory of Open Access Journals (Sweden)

    Victoria B Gradin

    Full Text Available Social exclusion is an influential concept in politics, mental health and social psychology. Studies on healthy subjects have implicated the medial prefrontal cortex (mPFC, a region involved in emotional and social information processing, in neural responses to social exclusion. Impairments in social interactions are common in schizophrenia and are associated with reduced quality of life. Core symptoms such as delusions usually have a social content. However little is known about the neural underpinnings of social abnormalities. The aim of this study was to investigate the neural substrates of social exclusion in schizophrenia. Patients with schizophrenia and healthy controls underwent fMRI while participating in a popular social exclusion paradigm. This task involves passing a 'ball' between the participant and two cartoon representations of other subjects. The extent of social exclusion (ball not being passed to the participant was parametrically varied throughout the task. Replicating previous findings, increasing social exclusion activated the mPFC in controls. In contrast, patients with schizophrenia failed to modulate mPFC responses with increasing exclusion. Furthermore, the blunted response to exclusion correlated with increased severity of positive symptoms. These data support the hypothesis that the neural response to social exclusion differs in schizophrenia, highlighting the mPFC as a potential substrate of impaired social interactions.

  19. Competitions between prosocial exclusions and punishments in finite populations

    Liu, Linjie; Chen, Xiaojie; Szolnoki, Attila

    2017-04-01

    Prosocial punishment has been proved to be a powerful mean to promote cooperation. Recent studies have found that social exclusion, which indeed can be regarded as a kind of punishment, can also support cooperation. However, if prosocial punishment and exclusion are both present, it is still unclear which strategy is more advantageous to curb free-riders. Here we first study the direct competition between different types of punishment and exclusion. We find that pool (peer) exclusion can always outperform pool (peer) punishment both in the optional and in the compulsory public goods game, no matter whether second-order sanctioning is considered or not. Furthermore, peer exclusion does better than pool exclusion both in the optional and in the compulsory game, but the situation is reversed in the presence of second-order exclusion. Finally, we extend the competition among all possible sanctioning strategies and find that peer exclusion can outperform all other strategies in the absence of second-order exclusion and punishment, while pool exclusion prevails when second-order sanctioning is possible. Our results demonstrate that exclusion is a more powerful strategy than punishment for the resolution of social dilemmas.

    Résumé Question Une fillette de 4 ans jouait avec le chien de ses voisins. Le chien s’est excité et a mordu la jeune fille à l’avant-bras, y laissant une plaie punctiforme. À cause cette blessure, elle s’est présentée à mon bureau. Devrais-je la traiter avec des antibiotiques? Quel antibiotique faut-il utiliser et pendant combien de temps? Réponse L’administration d’antibiotiques prophylactiques est indiquée lorsqu’on a procédé à une suture primitive de la morsure, que la plaie est de gravité modérée à sévère, qu’elle est punctiforme (particulièrement s’il y a eu pénétration de l’os, de la gaine tendineuse ou de l’articulation), pour les morsures au visage, aux mains, aux pieds ou aux parties génitales ou lorsque les victimes sont immunodéprimées ou souffrent d’asplénisme. L’antibiotique de première intention est l’amoxicilline-clavulanate. La prophylaxie appropriée antitétanique et contre la rage devrait faire partie des soins chez un patient qui a été mordu par un chien, tout comme le débridement local et le nettoyage complet de la plaie.

    L'objectif était de déterminer la prévalence de l'infection à VIH chez les patientes atteintes de cancer du sein et de comparer les caractéristiques anatomocliques et thérapeutiques de ces cancers du sein par rapports aux patientes non infectées par le VIH. Il s'agissait d'une étude rétrospective et analytique comparant les dossiers de patientes atteintes de cancers du sein histologiquement confirmés, infectées ou non par le VIH à l'unité de chirurgie oncologique de Donka, CHU de Conakry, de 2007 à 2012. Nous avons colligé 278 patientes présentant un cancer du sein dont 14 (5,0%) infectées par le VIH et 264 (95,0%) non infectées par le VIH. Les différences observées entre ces deux groupes de patientes étaient respectivement: âge médian (36,8 vs 49,0 ans), la ménopause (21,4% vs 53,4%), le nombre des patientes traitées (50,0% contre 77,1%) et la survenue de décès (78,6% vs 50,8%). Aucune différence n'a été notée dans la présentation clinique, histologique et le retard de consultation. Dans notre étude, la prévalence de l'infection à VIH chez les patients atteints de cancer du sein est élevée. L’âge jeune des patients, la faible accessibilité au traitement et la mortalité élevée doivent être confirmés par une étude sur un échantillon plus large. PMID:26523196

    The gambling industry has offered self-exclusion programs for quite a long time. Such measures are designed to limit access to gaming opportunities and provide problem gamblers with the help they need to cease or limit their gambling behaviour. However, few studies have empirically evaluated these programs. This study has three objectives: (1) to observe the participation in an improved self-exclusion program that includes an initial voluntary evaluation, phone support, and a mandatory meeting, (2) to evaluate satisfaction and usefulness of this service as perceived by self-excluders, (3) to measure the preliminary impact of this improved program. One hundred sixteen self-excluders completed a questionnaire about their satisfaction and their perception of the usefulness during the mandatory meeting. Among those participants, 39 attended an initial meeting. Comparisons between data collected at the initial meeting and data taken at the final meeting were made for those 39 participants. Data showed that gamblers chose the improved self-exclusion program 75% of the time; 25% preferred to sign a regular self-exclusion contract. Among those who chose the improved service, 40% wanted an initial voluntary evaluation and 37% of these individuals actually attended that meeting. Seventy percent of gamblers came to the mandatory meeting, which was a required condition to end their self-exclusion. The majority of participants were satisfied with the improved self-exclusion service and perceived it as useful. Major improvements were observed between the final and the initial evaluation on time and money spent, consequences of gambling, DSM-IV score, and psychological distress. The applicability of an improved self-exclusion program is discussed and, as shown in our study, the inclusion of a final mandatory meeting might not be so repulsive for self-excluders. Future research directives are also proposed.

    Full Text Available Este estudo abordou a condição de trabalho com deficiência no comércio ambulante de São Paulo, enquanto vivência de processos de exclusão e, paradoxalmente, de inclusão social. O trabalho é concebido pelos ambulantes como elemento que proporciona relacionamentos sociais e confere dignidade e respeito na rede de relações das próprias vidas, mas o plano da sociabilidade, porém, mostra-se contraditório. No ponto de vista do processo de trabalho, a atuação no comércio ambulante revela traços de degradação moral e política; a permanência de um esquema de corrupção, a imposição da subordinação, etc., expressam uma exclusão social, mas os vendedores ambulantes com deficiência não podem ser considerados excluídos. É mais apropriado considerar que aproximam-se da zona de vulnerabilidade, caracterizada por Castel pela instabilidade ocupacional e relacionai.This study addressed work conditions and disability in street vendor activity in São Paulo as experience of exclusion processes and, paradoxically, of social inclusion. Work is considered by street vendors the element providing social relationships and dignity and respect in the social network, within strict limits, it also means opportunity for autonomy, decision, management of their own lives. However, as to sociability it is controversial. In respect to work process, street vendor activity shows signs of moral and political degradation. Maintenance of a corruption scheme, imposition of subordination, etc., express social exclusion, but the disabled street vendors could not be considered as excluded. It is more appropriate to consider them as closer to the vulnerability zone, characterized by occupational and relational unstability, according to Castel.

    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....

    1998-07-01

    Full Text Available Les ombles chevaliers originaires du Léman se reproduisent à la fin de l'automne. En élevage, il est intéressant de retarder de quelques mois la période des ovulations car ce poisson a besoin d'une température inférieure à 6°C pendant l'ovulation. Il est plus facile de fournir une eau à cette température aux géniteurs retardés qui ovulent en hiver qu'à ceux qui ovulent naturellement en automne. Le conditionnement des ombles chevaliers en jours longs (17L-7N pendant l'automne permet de retarder de plusieurs mois la période des ovulations. Cette méthode a l'inconvénient de provoquer un étalement des ovulations sur plus de 3 mois. Le reconditionnement des géniteurs en jours courts en décembre supprime ce problème. L'efficacité du traitement en jours longs ne semble pas dépendre de la durée de son application pourvu que celle-ci dépasse 1,5 mois. Chez les femelles conditionnées en jours longs en automne et en hiver, les concentrations en gonadotropine plasmatique (GTH II sont très faibles. Le niveau de la GTH II plasmatique augmente trois semaines après un transfert en jours courts en janvier. Les concentrations de la GTH II plasmatique au cours de l'ovulation sont significativement plus faibles chez les femelles conditionnées en jours longs en janvier que chez les animaux reconditionnés en jours courts. A ce stade du cycle reproducteur, la GTH I plasmatique reste toujours à un niveau très faible, quel que soit le régime photopériodique. La pose d'implant de mélatonine chez les poissons ne modifie pas les sécrétions gonadotropes en jours longs comme en jours courts. La réceptivité hypophysaire des femelles à une stimulation de la sécrétion gonadotrope par une injection de GnRH n'est pas modifiée par le conditionnement des poissons en jours longs. Aucun effet du pimozide sur la sécrétion de la GTH II n'a pu être mis en évidence chez les géniteurs conditionnés en jours longs. Ces résultats permettent

    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.

    Most of radio observatories are located in isolated areas. Since radio sources from the universe is very weak, astronomer need to avoid radio frequency interference (RFI) from active spectrum users and radio noise produced by human made (telecommunication, mobile phone, microwave user and many more. There are many observatories around the world are surrounded by a Radio Quiet Zone (RQZ), which is it was set up using public or state laws. A Radio Quiet Zone normally consists of two areas: an exclusive area in which totally radio emissions are forbidden, with restrictions for residents and business developments, and a larger (radius up to 100 km above) coordination area where the power of radio transmission limits to threshold levels. Geographical Information System (GIS) can be used as a powerful tool in mapping large areas with varying RQZ profiles. In this paper, we report the initial testing of the usage of this system in order to identify the areas were suitable for Radio Quiet Zone. Among the important parameters used to develop the database for our GIS are population density, information on TV and telecommunication (mobile phones) transmitters, road networks (highway), and contour shielding. We will also use other information gathered from on-site RFI level measurements on selected 'best' areas generated by the GIS. The intention is to find the best site for the purpose of establishing first radio quiet zones for radio telescope in Malaysia.

  3. Model of reversible vesicular transport with exclusion

    Bressloff, Paul C; Karamched, Bhargav R

    2016-01-01

    A major question in neurobiology concerns the mechanics behind the motor-driven transport and delivery of vesicles to synaptic targets along the axon of a neuron. Experimental evidence suggests that the distribution of vesicles along the axon is relatively uniform and that vesicular delivery to synapses is reversible. A recent modeling study has made explicit the crucial role that reversibility in vesicular delivery to synapses plays in achieving uniformity in vesicle distribution, so called synaptic democracy (Bressloff et al 2015 Phys. Rev. Lett. 114 168101). In this paper we generalize the previous model by accounting for exclusion effects (hard-core repulsion) that may occur between molecular motor-cargo complexes (particles) moving along the same microtubule track. The resulting model takes the form of an exclusion process with four internal states, which distinguish between motile and stationary particles, and whether or not a particle is carrying vesicles. By applying a mean field approximation and an adiabatic approximation we reduce the system of ODEs describing the evolution of occupation numbers of the sites on a 1D lattice to a system of hydrodynamic equations in the continuum limit. We find that reversibility in vesicular delivery allows for synaptic democracy even in the presence of exclusion effects, although exclusion does exacerbate nonuniform distributions of vesicles in an axon when compared with a model without exclusion. We also uncover the relationship between our model and other models of exclusion processes with internal states. (paper)

  4. Two-channel totally asymmetric simple exclusion processes

    Pronina, Ekaterina; Kolomeisky, Anatoly B

    2004-01-01

    Totally asymmetric simple exclusion processes, consisting of two coupled parallel lattice chains with particles interacting with hard-core exclusion and moving along the channels and between them, are considered. In the limit of strong coupling between the channels, the particle currents, density profiles and a phase diagram are calculated exactly by mapping the system into an effective one-channel totally asymmetric exclusion model. For intermediate couplings, a simple approximate theory, that describes the particle dynamics in vertical clusters of two corresponding parallel sites exactly and neglects the correlations between different vertical clusters, is developed. It is found that, similarly to the case of one-channel totally asymmetric simple exclusion processes, there are three stationary state phases, although the phase boundaries and stationary properties strongly depend on inter-channel coupling. Extensive computer Monte Carlo simulations fully support the theoretical predictions

  5. Seed rain dynamics following disturbance exclusion in a secondary tropical dry forest in Morelos, Mexico.

    2009-01-01

    In most of the legally protected areas in Mexico local inhabitants use natural resources, such as fire wood or cattle grazing. These frequent but low-intensity disturbances have consequences at various levels of the tropical ecosystems and strongly impact forest structure and its regeneration capacity. Despite their importance, the effects of these perturbations in many aspects of tropical forest ecology and in the forest's capacity to recover after disturbance exclusion remain poorly understood. Understanding the impact of these processes on tropical forests is necessary for rehabilitating these forests and enhancing their productivity. In this study, we evaluate the impact of twelve years of exclusion (E) of cattle grazing and fire wood extraction in the composition and dynamics of seed rain, and compare this assessment to a similar analysis in an area where these perturbations continued (without exclusion, WE). We found a strong seasonality in seed rain (96% of seeds fell in the dry season) in both areas. There were no significant differences between E and WE sites in relation to overall seed density, species richness and diversity. However, the distribution along the year of seed species density was significantly different among the E and WE sites. The Jaccard's similarity index between E and WE sites was relatively low (0.57). Barochory was the most common dispersal mode observed among the 23 species in terms of seed species density (48%), followed by anemochory (39%) and zoochory (13%). In relation to seed density, anemochory was the most frequent dispersal mode (88%). Most species in the zone were categorized as small seeds (92%), and there were no significant differences in the distribution of seed size between E and WE. The spatial pattern of dispersal of the four species with the highest relative importance value index, in both areas, was aggregated. Twelve years of disturbance exclusion were not enough to fully restore the seed rain of the area; some

    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

  7. 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.

    Ultramafic blocks belonging to the Hochwart peridotite outcrop (Ulten Zone, Italian Alps) preserve a series of metasomatic mineral zones generated by infiltration of Si-rich hydrous fluids which occurred at the gneiss- peridotite interface. The age of the high pressure metamorphism for the Hochwart complex has been constrained at 330 Ma (Tumiati et al., 2003, EPSL, 210, 509-526). The country rocks are stromatic gneisses consisting mainly of quartz, K-feldspar, garnet, kyanite, biotite and muscovite. The ultramafic body consists of strongly serpentinized metaperidotites which are exposed as a hectometre-size lens along a steep gully, associated to monomineralic zones that developed at the contact between the peridotite body and the garnet gneiss country rocks. The composition of the metasomatic zones has been investigated in detail and records an order of metasomatic zoning formed by phlogopite-rich to tremolite-anthophyllite-rich rocks going from the host gneiss towards the peridotite. In some cases, the ultramafics fade into the gneisses developing serpentine and talc which has replaced, presumably at lower temperatures, the serpentine matrix and occurs in association with chlorite. Phlogopite aggregates (phlogopitite) with accessory minerals (quartz + zircon + apatite) and metabasic pods (phlogopite and hornblende) also occur. Black tourmaline (schorl-dravite solid solution) has been found for the first time in the contact near the phlogopite zone, suggesting an external addition of elements (boron and fluorine) to the system at high temperature. The formation of the metasomatic zones composed exclusively of hydrous phases must have involved extensive H2O-metasomatism as already documented for the Ulten peridotites. The source for these fluids can be a system of trondhjemitic-pegmatitic dikes cutting the peridotite that would have channelled aqueous fluids into the ultramafic rocks.

    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

    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

    Relocated Engdahl et al. (1998) global seismological data for 10 aftershock sequences were used to analyze the internal tectonic structure of the Central American subduction zone; the main shocks of several of these were the most destructive and often referenced earthquakes in the region (e.g., the 1970 Chiapas, 1983 Osa, 1992 Nicaragua, 1999 Quepos, 2001 El Salvador earthquakes). The spatial analysis of aftershock foci distribution was performed in a rotated Cartesian coordinate system (x, y, z) related to the Wadati-Benioff zone, and not in a standard coordinate system ($\\varphi$, λ, h are latitude, longitude, focal depth, respectively). Available fault plane solutions were also transformed into the plane approximating the Wadati-Benioff zone. The spatial distribution of earthquakes in each aftershock sequence was modeled as either a plane fit using a least squares approximation or a volume fit with a minimum thickness rectangular box. The analysis points to a quasi-planar distribution of earthquake foci in all aftershock sequences, manifesting the appurtenance of aftershocks to fracture zones. Geometrical parameters of fracture zones (strike, dip, and dimensions) hosting individual sequences were calculated and compared with the seafloor morphology of the Cocos Plate. The smooth character of the seafloor correlates with the aftershock fracture zones oriented parallel to the trench and commonly subparallel to the subducting slab, whereas subduction of the Cocos Ridge and seamounts around the Quepos Plateau coincides with steeply dipping fracture zones. Transformed focal mechanisms are almost exclusively (>90%) of normal character.

    La douleur chronique est souvent sous-détectée et insuffisamment traitée dans les milieux de soins de longue durée. Les outils d’autorapport (ou autoévaluation) de la douleur, comme l’échelle visuelle analogique, n’ont été validés que partiellement chez les populations âgées, en raison de la prévalence élevée de déficits visuels, auditifs, moteurs et cognitifs que l’on y trouve. Des outils d’observation des patients ont été développés pour pallier ces difficultés d’utilisation des échelles d’autorapport de la douleur. Le présent projet vise l’identification de ces échelles et leur évaluation sur la base de la validité de contenu (12 questions), de la validité de construit (12 questions), de la fiabilité (13 questions) et de l’utilité clinique (10 questions). Parmi les 24 instruments recensés, plusieurs apparaissent prometteurs pour évaluer la douleur chez les personnes âgées atteintes de démence sévère. Des efforts additionnels de validation sont cependant requis avant leur intégration à la pratique régulière en soins de longue durée. PMID:17717611

    2016-01-01

    The integration and adoption of digital technologies have enabled improvements in the quality of and inclusion in higher education. However, a significant proportion of the population has either remained or become digitally excluded. This systematic literature review elucidates the factors...... underlying the concepts of “digital exclusion” and the “digital divide” in higher education. The identified factors are grouped into three categories: social exclusion (i.e., low income, ICT-avoidance as the norm, lack of motivation and commitment, and physical or mental disability), digital exclusion (i.......e., lack of hardware devices and Internet services) and accessibility (which include the division between rural and urban areas, as well as disparities in ICT literacy and information literacy). These factors are multi-tiered and overlapping. Studies on the digital divide, digital exclusion, and barriers...

  15. Why Social Exclusion Persists among Older People in Australia

    2015-07-01

    Full Text Available The existing literature on social exclusion among older people, though relatively limited, suggests that disadvantage among older people is cumulative in nature. Some aspects of disadvantage starting at early life stages have long-term consequences. As such, older people with disadvantages may be subject to higher risks of persistent social exclusion. This article aims to improve understanding of social exclusion and its persistence among senior Australians in three ways. Firstly, the incidence of social exclusion among older people is analysed using selected indicators. Secondly, the study examines whether an older person experiencing social exclusion at one time is more likely to experience it again (persistence. Thirdly, it investigates what factors may be protecting older people from social exclusion. The analysis is conducted using the first eight waves of the Household, Income and Labour Dynamics in Australia (HILDA Survey. The sample of older people is disaggregated into a younger group (55–64 years at wave 1 and an older group (65+ years. The article suggests that higher education and income, as well as better health conditions and previous employment experiences, are important protective factors from social exclusion for older Australians.

    Eosinophilic colitis is induced by antigens present in cow's milk proteins in formula or human milk. In the last few years, an increasing number of cases have been diagnosed in exclusively breast-fed infants. We performed a retrospective study of 13 infants diagnosed with allergic colitis in our unit between January 1997 and January 2004. All the infants had been exclusively breast-fed. In all patients, initial symptoms were digestive (12 with mucus and bloody stools). Onset of symptoms occurred at 0-3 months in 77 %. Laboratory data of the allergic compound were negative. The main locations were the descending and sigmoid colon (75 %). Biopsy demonstrated acute inflammation, with neutrophil infiltration and an increase in eosinophils. In all patients, initial treatment consisted of exclusion of cow's milk proteins from the mother's diet. Ten of the 13 patients showed no improvement, requiring exclusive administration of protein-free hydrolyzate. In 3 infants, breastfeeding was maintained (breastfeeding without cow's milk proteins plus hydrolyzate). Diagnosis of eosinophilic colitis is based on exclusion of other causes of specific colitis and typical endoscopic and ultrastructural findings. Moreover, a satisfactory response to dietary treatment must be demonstrated. This diagnosis should be considered in breast-fed infants with rectal bleeding without involvement of general health status.

  18. The Relationship Between Exclusions from Gambling Arcades and Accessibility: Evidence from a Newly Introduced Exclusion Program in Hesse, Germany.

    2018-02-28

    An exclusion system for gambling arcades has been introduced recently in the state of Hesse. The aim of this paper is to identify significant predictors that are useful in explaining the variation of exclusions between different Hessian communities. Next to socio-demographic factors, we control for three different accessibility variables in two models: the number of electronic gambling machines (EGMs) in model I, and the number of locations and density of gambling machines at a location in model II. We disentangle the association between EGMs and exclusions of model I into a location and a clustering effect. Considering the socio-demographic variables, the explanatory power of our cross-sectional models is rather low. Only the age group of the 30-39 years old and those who are not in a partnership (in model I) yield significant results. As self-exclusion systems reduce availability for the group of vulnerable players, this analysis provides evidence for the assumption that the two groups-pathological gamblers and vulnerable players-seem to have little overlap concerning sociodemographic characteristics. The accessibility variables, on the other hand, turn out to be significantly associated with the number of exclusions. All three of them are statistically significant and their association is positive. The results of model II show that the location effect is more pronounced then the clustering effect of EGMs, i.e. the effect of an additional single-licensed arcade on the number of exclusions is stronger than the increase in the number of license at one location.

    Full Text Available Background: Breastfeeding is the unique source of nutrition and it plays an important role in the growth, development and survival of the infants. The initiation of breastfeeding within one hour and continuation of only breast milk up to six months ensure maximum benefits. The prevalence of exclusive breastfeeding in Bangladesh is 56% which is low. We designed this study to find out the factors influencing the duration of breastfeeding in Bangladeshi population. Objective: To study the factors influencing noncompliance to exclusive breastfeeding. Materials and Methods: This cross sectional study was conducted in Dhaka Shishu Hospital during the period January to June 2011. It includes 125 infant (1–12 months-mother pairs randomly selected from the inpatient and outpatient departments of Dhaka Shishu Hospital. Mother-infant pairs were divided into two groups based on continuation of only breastfeeding up to six months. Outcomes were compared between two groups. Results: In this study exclusive breastfeeding was found in 27.2% and nonexclusive breastfeeding was in 72.8% cases. It was found that in most cases (40% termination of breastfeeding was at 3--4 months. The study revealed that insufficient milk production due to poor position and attachment, social factors such as influence of husband and other family members, joining to service etc act as barrier to exclusive breastfeeding. Mass media and advice from health professionals had a higher influence on lower rate of exclusive breastfeeding. Women who were multiparous, housewives were more likely to maintain optimal breastfeeding. Conclusion: The present study reveals some important factors contributing to low rate of exclusive breastfeeding in Bangladesh.

    2013-01-01

    The exclusive photoproduction of Υ has been studied with the ZEUS detector in ep collisions at HERA. The exponential slope, b, of the |t|-dependence of the cross section, where t is the squared four-momentum transfer at the proton vertex, has been measured. This constitutes the first measurement of the |t|-dependence of the γp→Υp cross section. The differential crosssections as a function of t at lower energies of γp centre-of-mass has been studied in exclusive diffractive photoproduction of J/ψ mesons with the H1 detector. The exclusive electroproduction of two pions has been measured by the ZEUS experiment. The two-pion invariant-mass distribution is interpreted in terms of the pion electromagnetic form factor, assuming that the studied mass range includes the contributions of the ρ, ρ′ and . ρ'' vector-meson states.

  4. FINANCIAL EXCLUSION OF THE RURAL POPULATION IN POLAND

    Directory of Open Access Journals (Sweden)

    Ryszard Kata

    2015-12-01

    Full Text Available The paper attempts to assess the extent of fi nancial exclusion of the rural population in Poland. One of the most basic measures of fi nancial exclusion is percentage of adult residents lacking a bank account. This and other measures verifying the population’s use of fundamental banking services and the statistical data on development of banking infrastructure in the territorial context were then employed to conduct an assessment of the extent and causes of fi nancial exclusion with a particular emphasis on the rural areas. The fi ndings show that, like in many other countries, the extent of provision of fi nancial services among the rural population is more limited compared to the urban population. The fi nancial exclusion, has much deeper roots going beyond the geographical factors. The real causes of the fi nancial exclusion lie not only in access to banking services but also in their price, the population’s income, as well as being strongly aff ected by information and behaviour.

  5. 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)

"Delta zone" was defined as part of gamma zone in which blood vessels of at least 50 µm diameter were not present over a length of >300 µm. Beta zone (mean length:0.35±0.52 mm was significantly (P = 0.01 larger in the glaucoma group than in the non-glaucomatous group. It was not significantly (P = 0.28 associated with axial length. Beta zone was significantly (P = 0.004 larger than the region with occluded choriocapillaris. Gamma zone (mean length:0.63±1.25 mm was associated with axial length (P50 µm diameter within gamma zone was present only in highly axially elongated globes and was not related with glaucoma. Beta zone (Bruch's membrane without RPE was correlated with glaucoma but not with globe elongation. Since the region with occluded choriocapillaris was smaller than beta zone, complete loss of RPE may have occurred before complete choriocapillaris closure.

    We investigate the role of exclusive channels in semi-inclusive electroproduction of pions and kaons. Using the QCD factorization theorem for hard exclusive processes we evaluate the cross sections for exclusive pseudoscalar and vector meson production in terms of generalized parton distributions and meson distribution amplitudes. We investigate the uncertainties arising from the modeling of the nonperturbative input quantities. Combining these results with available experimental data, we compare the cross sections for exclusive channels to that obtained from quark fragmentation in semi-inclusive deep inelastic scattering. We find that rho0 production is the only exclusive channel with significant contributions to semi-inclusive pion production at large z and moderate Q2. The corresponding contribution to kaon production from the decay of exclusively produced phi and Kstar is rather small

  16. Saturated Zone Colloid Transport

    H. S. Viswanathan

    2004-01-01

    This scientific analysis provides retardation factors for colloids transporting in the saturated zone (SZ) and the unsaturated zone (UZ). These retardation factors represent the reversible chemical and physical filtration of colloids in the SZ. The value of the colloid retardation factor, R col is dependent on several factors, such as colloid size, colloid type, and geochemical conditions (e.g., pH, Eh, and ionic strength). These factors are folded into the distributions of R col that have been developed from field and experimental data collected under varying geochemical conditions with different colloid types and sizes. Attachment rate constants, k att , and detachment rate constants, k det , of colloids to the fracture surface have been measured for the fractured volcanics, and separate R col uncertainty distributions have been developed for attachment and detachment to clastic material and mineral grains in the alluvium. Radionuclides such as plutonium and americium sorb mostly (90 to 99 percent) irreversibly to colloids (BSC 2004 [DIRS 170025], Section 6.3.3.2). The colloid retardation factors developed in this analysis are needed to simulate the transport of radionuclides that are irreversibly sorbed onto colloids; this transport is discussed in the model report ''Site-Scale Saturated Zone Transport'' (BSC 2004 [DIRS 170036]). Although it is not exclusive to any particular radionuclide release scenario, this scientific analysis especially addresses those scenarios pertaining to evidence from waste-degradation experiments, which indicate that plutonium and americium may be irreversibly attached to colloids for the time scales of interest. A section of this report will also discuss the validity of using microspheres as analogs to colloids in some of the lab and field experiments used to obtain the colloid retardation factors. In addition, a small fraction of colloids travels with the groundwater without any significant retardation. Radionuclides irreversibly

    We report the results on the searches of exclusive production of low- and high-mass pairs with the Compact Muon Solenoid (CMS) detector in proton-proton collisions at $\\sqrt{s}$ = 7 TeV. The analyses comprise the central exclusive $\\gamma\\gamma$ production, the exclusive two-photon production of dileptons, $e^{+}e^{-}$ and $\\mu^{+}\\mu^{-}$, and the exclusive two-photon production of $W$ pairs in the asymmetric $e^{\\pm}\\mu^{\\mp}$ decay channel. No diphotons candidates are observed in data and an upper limit on the cross section is set to 1.18 pb with 95% confidence level for $E_{T}(\\gamma)>$ 5.5 GeV and $|\\eta(\\gamma)|$ 5.5 GeV and $|\\eta(e)|$ 11.5 GeV, $p_{\\textrm{T}}(\\mu)>$ 4 GeV and $|\\eta(\\mu)|$ 4 GeV, $|\\eta(\\mu)|$ 20 GeV. Moreover, the study of the tail of the dilepton transverse momentum distribution resulted in model-independent upper limits for the anomalous quartic gauge couplings, which are of the order of 10$^{-4}$.

O diagnóstico depende da exclusão de causas não clonais e reversíveis. Especialmente nas fases mais precoces da doença, na ausência de excesso de blastos, sideroblastos em anel ou alteração citogenética clonal, o diagnóstico requer um protocolo de exclusão. A exposição recente a agentes tóxicos ou drogas citostáticas, a deficiência de vitamina B12 e ácido fólico e o uso recente de fatores de crescimento são considerados fatores de exclusão absolutos. O etilismo, a anemia da doença crônica, distúrbios metabólicos, hormonais, auto-imunes e infecções virais devem ser excluídos ou interpretados com cautela. Outras doenças da célula-tronco hematopoética devem ser consideradas, sobretudo na SMD hipocelular.

    Full Text Available Discriminatory and marginalising discourses affect the cultural and social realities of people in all human societies. Across time and place, these discourses manifest in numerous tangible and intangible ways, creating stigma and forms of exclusion by means particular to their cultural, historical, political and social contexts. These discourses also manifest in varying degrees of harm; from verbal abuse and behavioural forms of exclusion, to physical abuse and neglect, and exclusionary practices at institutional, legal and regulatory levels. Such forms of stigma cause direct physical and mental harm and other forms of persecution. The papers in this special issue arise from a one-day symposium held at the University of Queensland in February 2013. The symposium, ‘Stigma and Exclusion in Cross-Cultural Contexts’, brought together researchers and community-based practitioners from across Australia and overseas to explore marginalization, discriminatory discourses and stigma in a wide range of historical and cross-cultural settings. By critically engaging with experiences of social, political and cultural exclusion and marginalisation in different contexts, we aimed to elucidate how discourses of stigma are created, contested and negotiated in cross-cultural settings. We also aimed to explore stigmatisation in its lived realities: as discourses of exclusion; as the fleshy reality of discrimination in social worlds; as part of the life narratives of individuals and groups; and as discourses of agency and counter-discourses in responding to stigma.

    Interactions of surfactants with solid substrates are important in the controlling of processes such as flotation, coating, flocculation and sedimentation. These interactions usually lead to adsorption on solids, but can also result in an exclusion of the reagents with dire consequences. In this work electrostatic exclusion of negatively charged dodecylbenzene sulfonate micelles from quartz/water, Bio-Sil/water and alumina/water interfaces has been investigated as a function of pH and ionic strength. Measurable negative adsorption of these surfactants from similarly charged solid/liquid interface was observed in the micellar region. In the case of porous samples with large surface area, comparison of pore size with the micelle size is necessary to avoid any erroneous conclusions regarding the role of electrostatic exclusion in a given system. A theoretical model for the electrostatic exclusion of micelles is developed and used to calculate the adsorption of negatively charged dodecylbenzene sulfonate on negatively charged quartz (pH 7), silica (Bio-Sil A, pH 3) and alumina (pH 11) in the micellar concentration region. The micellar exclusion values calculated using the model are in excellent agreement with the experimental results.

    No research, to date, has investigated the role of ethnic school composition (and intergroup contact) on European-American youth's use of stereotypes to explain interracial discomfort in the context of peer exclusion. In this study European-American 4 th , 7 th and 10 th grade students ( N = 414), attending low and high ethnically diverse public schools (with low and high self-reports of cross-race/ethnic friendships, respectively) evaluated three contexts of interracial exclusion (at lunch time, at a school dance, and at a sleepover). In addition to age and context effects, participants enrolled in high diversity schools were less likely to use stereotypes to explain racial discomfort, more likely to view racial exclusion as wrong, and more likely to estimate that racial exclusion occurs, than were participants enrolled in low diversity schools. These findings have implications for the role of social experience on racial attitudes and judgments about exclusion.

    For some youth, early puberty is accompanied by peer exclusion. Yet early developers may experience less peer exclusion if they have social competence, which would bolster their ability to develop and maintain positive relationships with their peers. Accordingly, the present study tests whether pubertal timing and tempo predicts decrements in children's social competence and whether decrements in social competence account for associations between puberty (timing and tempo) and peer exclusion over time. Longitudinal data were drawn from 1364 families (48% female; 76% White; M = 9.32 years, SD = .48, at Wave 3) who participated in Waves 3-5 (i.e., grades 4-6) of Phase III of the NICHD-SECCYD. The results from latent growth curve models indicated that earlier pubertal timing and more rapid pubertal tempo among girls were associated with high initial levels of peer exclusion. Moreover, mediation analyses revealed that early developers' susceptibility to peer exclusion was associated with their initial level of social competence. In boys, pubertal timing and tempo were not directly associated with peer exclusion; instead, indirect effects of pubertal timing on peer exclusion (intercept, slope) occurred through initial levels of social competence. On average, early developers' who had low levels of social competence also had high initial levels of peer exclusion but experienced decrements in peer exclusion over time. The association between the intercepts for puberty and peer exclusion and the slopes for social competence and peer exclusion were stronger for boys than girls. Overall, our findings suggest that early developers' susceptibility to and experiences of peer exclusion are associated with their development of social competence.

    Cette étude rapporte les aspects cliniques et évolutifs des séquelles pulmonaires tuberculeuses (SPT) opérées chez les séropositifs (VIH+). Il s'agit d'une étude prospective transversale réalisée entre Novembre 2005 et Octobre 2012. Elle a porté sur 20 patients VIH+, ayant dans leurs antécédents, une tuberculose pulmonaire (TP) traitée et déclarée guérie, et admise dans ladite période pour une chirurgie de la SPT secondaire. Une enquête sérologique VIH a été réalisée systématiquement au cours du bilan pré-opératoire. Le diagnostic pré-opératoire de la SPT, la mortalité, les complications post- opératoires (CPOP), le séjour hospitalier, le suivi à moyen terme des STP opérées ont été évalués. Les séropositifs étaient VIH1+ (n = 12; 60%), VIH1&2+ (n = 4; 20%) et VIH2+ (n = 4; 20%). La durée moyenne d’évolution des STP était de 26,22 ± 21,3 mois. Les STP étaient les pyothorax ou pleurésies enkystées (n = 16; 80%), le poumon détruit (n = 2;10%) et les dilatations de bronches (n = 2;10%). Les VIH+ ne présentaient pas d'aspergillome pulmonaire. Le séjour hospitalier moyen était 13,1 ± 10,2 jours. Le suivi total était de 82 patients-année avec une moyenne de suivi de 4,2 ± 2,3 ans (extrêmes: 1 et 7 ans). Le taux de mortalité à court et moyen terme était nul. Aucun décès post-opératoire immédiat n'a été noté. Les CPOP immédiates étaient les bullages prolongés chez 75% des immunodéprimés. Les CPOP tardives (n = 3) étaient un syndrome restrictif pulmonaire, un pyothorax persistant et une pachypleurite résiduelle restrictive. A court terme, le taux de guérison radiologique était de 80% (n = 16). PMID:24932331

    overall results of cerebral scintigraphy are less favourable in the case of cerebral tumours in children than in that of adults. The reason for this is the high frequency in children of tumours of the brain stem, the pituitary and the third ventricle, the detectability of which is low. However, very good results were obtained in the case of 35 tumours of the cerebellum and the fourth ventricle as a result of using very rigorous techniques. Excellent results have also been obtained with other surgical lesions, such as chronic subdural haematoma in the nursing infant and vascular malformations. In conditions not amenable to neurosurgery definitely false results were the exception. Lastly, the authors present the initial results of a study of the cerebral cisterns and ventricles. They emphasize the abundance of information supplied by these scintigraphic methods and their great utility for the neurosurgeon.

    This study examined children's judgements and emotions associated with weight-based social exclusion using an ethnically diverse sample of one hundred and seventeen 9- and 13-year-old children. Children were interviewed about three scenarios depicting weight-based exclusion in athletic, academic, and social contexts. Children's judgements of exclusion, emotions attributed to the excluder and excluded targets, and justifications for judgements and emotions were examined. Overall, children judged weight-based exclusion to be wrong for moral reasons. However, they viewed weight-based exclusion in athletic contexts as less wrong compared with academic contexts, and they used more social-conventional reasoning to justify judgements and emotions attributed to excluders in athletic contexts compared with academic and social contexts. Children also expected excluded targets to feel negative emotions, whereas a range of positive and negative emotions was attributed to excluders. In addition, older children were more accepting of weight-based exclusion in athletic contexts than in academic and social contexts. We discuss the results in relation to the development of children's understanding of, and emotions associated with, exclusion based on weight. © 2014 The British Psychological Society.

  12. Des recommandations probantes pour surveiller l’innocuité des antipsychotiques de deuxième génération chez les enfants et les adolescents

    HISTORIQUE : Au Canada, l’utilisation d’antipsychotiques, notamment les antipsychotiques de deuxième génération (ADG), a augmenté de façon considérable depuis cinq ans chez les enfants ayant des troubles de santé mentale. Ces médicaments ont le potentiel de causer de graves complications métaboliques et neurologiques lorsqu’on les utilise de manière chronique. OBJECTIF : Synthétiser les données probantes relatives aux effets secondaires métaboliques et neurologiques précis associés à l’usage d’ADG chez les enfants et fournir des recommandations probantes sur la surveillance de ces effets secondaires. MÉTHODOLOGIE : Les auteurs ont procédé à une analyse systématique des essais cliniques contrôlés des ADG auprès d’enfants. Ils ont fait des recommandations à l’égard de la surveillance de l’innocuité des ADG d’après un modèle de classification fondé sur le système GRADE (système de notation de l’évaluation et de l’élaboration des recommandations). Lorsque les données probantes n’étaient pas suffisantes, ils fondaient leurs recommandations sur le consensus et l’avis d’experts. Un groupe consensuel multidisciplinaire a analysé toutes les données probantes pertinentes et est parvenu à un consensus à l’égard des recommandations. RÉSULTATS : Les recommandations probantes portant sur la surveillance de l’innocuité des ADG figurent dans les présentes lignes directrices. Les auteurs indiquent la qualité des recommandations relatives à des examens physiques et tests de laboratoire précis à l’égard de chaque ADG à des moments déterminés. CONCLUSION : De multiples essais aléatoires et contrôlés ont permis d’évaluer l’efficacité de bon nombre des ADG utilisés pour traiter les troubles de santé mentale en pédiatrie. Toutefois, leurs avantages ne sont pas sans risques : on observe à la fois des effets secondaires métaboliques et neurologiques chez les enfants traités au moyen d

    There is growing literature exploring the possibility of parallel retrieval of location memories, although this literature focuses primarily on the speed of retrieval with little attention to the accuracy of location memory recall. Baguley, Lansdale, Lines, and Parkin (2006) found that when a person has two or more memories for an object's location, their recall accuracy suggests that only one representation can be retrieved at a time (exclusivity). This finding is counterintuitive given evidence of non-exclusive recall in the wider memory literature. The current experiment explored the exclusivity effect further and aimed to promote an alternative outcome (i.e., independence or superadditivity) by encouraging the participants to combine multiple representations of space at encoding or retrieval. This was encouraged by using anchor (points of reference) labels that could be combined to form a single strongly associated combination. It was hypothesised that the ability to combine the anchor labels would allow the two representations to be retrieved concurrently, generating higher levels of recall accuracy. The results demonstrate further support for the exclusivity hypothesis, showing no significant improvement in recall accuracy when there are multiple representations of a target object's location as compared to a single representation.

  15. Rationality alters the rank between peer punishment and social exclusion

    Peer punishment and social exclusion are two ways to punish free-riders. Previous work usually focuses on how their presence, either peer punishment or social exclusion, shapes the evolution of cooperation. Little attention has been given to which of these two strategies is favored by natural selection when they are both present. Here we investigate how rationality alters the ranking of these two strategies. Under weak rationality, for compulsory public goods games, peer punishment has an evolutionary advantage over social exclusion if the efficiency of punishment or the cost of exclusion is high. Furthermore, this rank is preserved for voluntary public goods games where loners are involved. Under strong rationality, however, peer punishment cannot prevail over social exclusion for both compulsory and voluntary public goods games. This indicates that rationality greatly alters the rank between peer punishment and social exclusion. Moreover, we find that this ranking is sensitive to the rationality. Our work thus gives an insight into how different types of punishment evolve.

  16. Social exclusion impairs distractor suppression but not target enhancement in selective attention.

    Social exclusion has been thought to weaken one's ability to exert inhibitory control. Existing studies have primarily focused on the relationship between exclusion and behavioral inhibition, and have reported that exclusion impairs behavioral inhibition. However, whether exclusion also affects selective attention, another important aspect of inhibitory control, remains unknown. Therefore, the current study aimed to explore whether social exclusion impairs selective attention, and to specifically examine its effect on two hypothesized mechanisms of selective attention: target enhancement and distractor suppression. The Cyberball game was used to manipulate social exclusion. Participants then performed a visual search task while event-related potentials were recorded. In the visual search task, target and salient distractor were either both presented laterally or one was presented on the vertical midline and the other laterally. Results showed that social exclusion differentially affected target and distractor processing. While exclusion impaired distractor suppression, reflected as smaller distractor-positivity (Pd) amplitudes for the exclusion group compared to the inclusion group, it did not affect target enhancement, reflected as similar target-negativity (Nt) amplitudes for both the exclusion and inclusion groups. Together, these results extend our understanding of the relationship between exclusion and inhibitory control, and suggest that social exclusion affects selective attention in a more complex manner than previously thought.

  17. ''Follow that quark!'' (and other exclusive stories)

    International Nuclear Information System (INIS)

    Carroll, A.S.

    1987-01-01

    Quarks are considered to be the basic constituents of matter. In a series of recent experiments, Carroll studied exclusive reactions as a means of determining the interactions between quarks. Quantum Chromo-dynamics (QCD) is the modern theory of the interaction of quarks. This theory explains how quarks are held together via the strong interaction in particles known as hadrons. Hadrons consisting of three quarks are called baryons. Hadrons made up of a quark and an antiquark are called mesons. In his lecture, Carroll describes what happens when two hadrons collide and scatter to large angles. The violence of the collision causes the gluons that bind the quarks in a particular hadron to temporarily lose their grip on particular quarks. Quarks scramble toward renewed unity with other quarks, and they undergo rearrangement, which generally results in additional new particles. A two-body exclusive reaction has occurred when the same number of particles exist before and after the collisions. At large angles these exclusive reactions are very rare. The labels on the quarks known as flavor enable the experimenter to follow the history of individual quarks in detail during these exclusive reactions. Carroll describes the equipment used in the experiment to measure short distance, hard collisions at large angles. The collisions he discusses occur when a known beam of mesons or protons collide with a stationary proton target. Finally, Carroll summarizes what the experiments have shown from the study of exclusive reactions and what light some of their results shed on the theory of QCD

    2015-02-21

    The pathogen exclusion problem is the problem of finding control measures that will exclude a pathogen from an ecological system or, if the system is already disease-free, maintain it in that state. To solve this problem we work within a holistic control theory framework which is consistent with conventional theory for simple systems (where there is no external forcing and constant controls) and seamlessly generalises to complex systems that are subject to multiple component seasonal forcing and targeted variable controls. We develop, customise and integrate a range of numerical and algebraic procedures that provide a coherent methodology powerful enough to solve the exclusion problem in the general case. An important aspect of our solution procedure is its two-stage structure which reveals the epidemiological consequences of the controls used for exclusion. This information augments technical and economic considerations in the design of an acceptable exclusion strategy. Our methodology is used in two examples to show how time-varying controls can exploit the interference and reinforcement created by the external and internal lag structure and encourage the system to 'take over' some of the exclusion effort. On-off control switching, resonant amplification, optimality and controllability are important issues that emerge in the discussion. Copyright © 2014 Elsevier Ltd. All rights reserved.

    The best nourishment for infants during the first 6 months of life is exclusive breastfeeding. It is recommended along with other food to complement the diet until the child is 2 years old, as long as the mother and the child are willing to continue with it. The objectives of this study were to determine he exclusive breastfeeding rate in full term newborns at hospital discharge and 15 days later and to analyze the factors that positively affect the exclusive breastfeeding. A prospective study was conducted in which a sample of postpartum women with full term newborns was recruited during hospital admission. Different variables were compiled and two interviews were made to determine the kind of feeding they were giving their children and if it was maintained at 15 days of birth. Exclusive breastfeeding rate at hospital discharge is much lower than recommended. It significantly decreases at 15 days of birth, increasing artificial feeding. It seems that having a vaginal birth, no complications giving birth, providing early breastfeeding and skin-to-skin contact in the delivery room are predisposing factors necessary to establish a good breastfeeding at hospital discharge. Despite the efforts of professionals, the percentage of newborns with exclusive breastfeeding at birth is not enough for the current recommendations. Copyright: © 2018 Permanyer.

    Our aim was to analyze the outcomes of endovascular exclusion of the entire aortic arch (proximal landing in zone 0, distal landing in zone III or beyond, after Ishimaru) in which complete surgical debranching of the supra-aortic vessels (I), endovascular supra-aortic revascularization (chimney, fenestrated, or branched grafts) with partial surgical debranching (II), or total endovascular supra-aortic revascularization (III) was additionally performed. Publications describing endovascular repair of the aortic arch (2000-2016) were systematically searched and reviewed. From a total of 53 relevant studies including 1853 patients, only 1021 patients undergoing 35 different total aortic arch procedures were found eligible for further evaluation and included in group I, II, or III (429, 190, and 402 patients, respectively). Overall early mortality was higher in group I vs groups II and III (P = .001; 1 - β = 95.6%) but exceeded in group III (18.6%) and group II (14.0%) vs group I (8.0%; P = .044; 1 - β = 57.4%) for diseases involving zone 0. Mortality was higher in all subgroups treated for zone 0 disease compared with corresponding subgroups treated for zone I to zone III disease. The incidence of cerebral ischemic events was increased in groups I and II vs group III (7.5% and 11% vs 1.7%; P = .0001) and correlated with early mortality (R 2  = .20; P = .033). The incidence of type II endoleaks and endovascular reintervention was similar between groups and correlated with each other (R 2  = .37; P = .004). Type Ia endoleak occurred more often in groups II and III than in group I (7.1% and 12.1% vs 5.8%; P = .023) and correlated with midterm mortality (R 2  = .53; P = .005). Retrograde type A dissection was low in all groups, whereas aneurysm growth was higher in group III (2.6%, 4.2%, 10.7%; P = .002), correlating with midterm mortality (R 2  = .311; P = .009). Surgical revision slightly correlated with surgical complications (R 2  = .18; P = .044

    Observing social exclusion can be a distressing experience for children that can be followed by concerns for self-inclusion (self-concerns), as well as prosocial behavior to help others in distress (other-concerns). Indeed, behavioral studies have shown that observed social exclusion elicits prosocial compensating behavior in children, but motivations for the compensation of social exclusion are not well understood. To distinguish between self-concerns and other-concerns when observing social exclusion in childhood, participants (aged 7-10) played a four-player Prosocial Cyberball Game in which they could toss a ball to three other players. When one player was excluded by the two other players, the participant could compensate for this exclusion by tossing the ball more often to the excluded player. Using a three-sample replication (N = 18, N = 27, and N = 26) and meta-analysis design, we demonstrated consistent prosocial compensating behavior in children in response to observing social exclusion. On a neural level, we found activity in reward and salience related areas (striatum and dorsal anterior cingulate cortex (dACC)) when participants experienced inclusion, and activity in social perception related areas (orbitofrontal cortex) when participants experienced exclusion. In contrast, no condition specific neural effects were observed for prosocial compensating behavior. These findings suggest that in childhood observed social exclusion is associated with stronger neural activity for self-concern. This study aims to overcome some of the issues of replicability in developmental psychology and neuroscience by using a replication and meta-analysis design, showing consistent prosocial compensating behavior to the excluded player, and replicable neural correlates of experiencing exclusion and inclusion during middle childhood.

Microencapsulation process with spray drying method decreased antagonistic ability of probiotic against pathogenic bacteria both in single and multi strain.

  7. International arbitration and its exclusion from the Brussels regime

    2016-06-01

    Full Text Available The Brussels regime, which regulates the matters of transnational litigation excludes arbitration from its scope. Upon formation of the Brussels regime the existing instruments concerning arbitration - the United Nations Convention on Recognition and Enforcement of Foreign Arbitral Awards and the 1961 European Convention on International Commercial Arbitration - were believed to be sufficient. The original Brussels Convention 1968 on recognition and enforcement of judgments delivered in the courts of the EU Member States expressly provided for the exclusion of arbitration. The following Brussels I Regulation followed the trend and reinforced the exclusion of arbitration from their material scopes. The rationale for doing so was primarily the prevention of parallel proceedings and irreconcilable judgments. The arbitration exclusion from the Brussels regime has caused a fair amount of confusion, especially regarding the extent and limits of the exclusion. That is, whether the arbitration agreement, the arbitral award and its consequences are covered by the exclusion or they may fall under the scope of the Brussels regulation if they constitute only an incidental question to the main cause of action? The confusion was illustrated in the ECJ judgment West Tankers, which generated negative feedback from the arbitration community and indicated the need for reform. The recently adopted Recast Regulation took it upon itself to clarify the relationship between arbitration and the EU regime of transnational litigation. The exclusion is reinforced ye again and its boundaries are specified in the Preamble. However, whether or not the concerns about the extent and objectives of arbitration exclusion have been at present eliminated, remains to be seen.

  9. Multispecies exclusion process with fusion and fission of rods: A model inspired by intraflagellar transport

    Patra, Swayamshree; Chowdhury, Debashish

    2018-01-01

    We introduce a multispecies exclusion model where length-conserving probabilistic fusion and fission of the hard rods are allowed. Although all rods enter the system with the same initial length ℓ =1 , their length can keep changing, because of fusion and fission, as they move in a step-by-step manner towards the exit. Two neighboring hard rods of lengths ℓ1 and ℓ2 can fuse into a single rod of longer length ℓ =ℓ1+ℓ2 provided ℓ ≤N . Similarly, length-conserving fission of a rod of length ℓ'≤N results in two shorter daughter rods. Based on the extremum current hypothesis, we plot the phase diagram of the model under open boundary conditions utilizing the results derived for the same model under periodic boundary condition using mean-field approximation. The density profile and the flux profile of rods are in excellent agreement with computer simulations. Although the fusion and fission of the rods are motivated by similar phenomena observed in intraflagellar transport (IFT) in eukaryotic flagella, this exclusion model is too simple to account for the quantitative experimental data for any specific organism. Nevertheless, the concepts of "flux profile" and "transition zone" that emerge from the interplay of fusion and fission in this model are likely to have important implications for IFT and for other similar transport phenomena in long cell protrusions.

    To assess the interchangeability of zone-specific (peripheral-zone (PZ) and transition-zone (TZ)) multiparametric-MRI (mp-MRI) logistic-regression (LR) models for classification of prostate cancer. Two hundred and thirty-one patients (70 TZ training-cohort; 76 PZ training-cohort; 85 TZ temporal validation-cohort) underwent mp-MRI and transperineal-template-prostate-mapping biopsy. PZ and TZ uni/multi-variate mp-MRI LR-models for classification of significant cancer (any cancer-core-length (CCL) with Gleason > 3 + 3 or any grade with CCL ≥ 4 mm) were derived from the respective cohorts and validated within the same zone by leave-one-out analysis. Inter-zonal performance was tested by applying TZ models to the PZ training-cohort and vice-versa. Classification performance of TZ models for TZ cancer was further assessed in the TZ validation-cohort. ROC area-under-curve (ROC-AUC) analysis was used to compare models. The univariate parameters with the best classification performance were the normalised T2 signal (T2nSI) within the TZ (ROC-AUC = 0.77) and normalized early contrast-enhanced T1 signal (DCE-nSI) within the PZ (ROC-AUC = 0.79). Performance was not significantly improved by bi-variate/tri-variate modelling. PZ models that contained DCE-nSI performed poorly in classification of TZ cancer. The TZ model based solely on maximum-enhancement poorly classified PZ cancer. LR-models dependent on DCE-MRI parameters alone are not interchangeable between prostatic zones; however, models based exclusively on T2 and/or ADC are more robust for inter-zonal application.

    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)

  14. Radiation protection zoning

    International Nuclear Information System (INIS)

    2015-01-01

    Radiation being not visible, the zoning of an area containing radioactive sources is important in terms of safety. Concerning radiation protection, 2 work zones are defined by regulations: the monitored zone and the controlled zone. The ministerial order of 15 may 2006 settles the frontier between the 2 zones in terms of radiation dose rates, the rules for access and the safety standards in both zones. Radioprotection rules and the name of the person responsible for radiation protection must be displayed. The frontier between the 2 zones must be materialized and marked with adequate equipment (specific danger signs and tapes). Both zones are submitted to selective entrance, the access for the controlled zone is limited because of the radiation risk and of the necessity of confining radioactive contamination while the limitation of the access to the monitored zone is due to radiation risk only.

    Exclusive vector meson photoproduction is studied in ultra-peripheral pPb collisions at $\\sqrt{s_{NN}} = 5.02$ TeV. The cross sections are measured as a function of the photon-proton centre-of-mass energy, extending the energy range explored by H1 and ZEUS Experiments at HERA. In addition, the differential cross sections ($d\\sigma/d\\left |t\\right|$), where $\\left |t\\right|\\approx p^{2}_{T}$ is the squared transverse momentum of produced vector mesons, are measured and the slope parameters are obtained. The results are compared to previous measurements and to theoretical predictions. We also report a measurement of the exclusive or quasi-exclusive $W^{+}W^{-}$ production in pp collisions at $\\sqrt{s} = 8$ TeV ($7$ TeV) using data corresponding to an integrated luminosity of $19.7$ fb$^{-1}$ ($5.5$fb$^{-1}$), respectively. In this study, we look for any deviations that there might be from the Standard Model, and the results are used to set limits on the Anomalous Quartic Gauge Couplings. Finally, the latest p...

Celui-ci tire sa puissance prescriptive de l’a priori pratique où il s’inscrit. C’est à une opération de production de soi que l’exercice spirituel donne lieu : l’analyse des quatre premières Méditations chrétiennes et métaphysiques, en particulier, montre que c’est une organisation de la substance personnelle que provoque le travail spirituel sur soi. Celui-ci consiste à déterminer le rapport à soi comme relation d’une vision attentive à une activité illuminante, par un décentrement textuel du « je » vers le « tu ».One of the major Malebranche’s assertion, that we see truth in God, is not a mere theoretical thesis. I study first the Méditations pour se disposer à l’Humilité et à la pénitence and compare them with François de Sales’ spiritual exercitations, and show that prayer, meditation and contemplation constitute the practical frameworks of this period. The text of the Méditations is an apparatus which is fit to cause an effect in its target – the self of the reader : the vision in God. The practical a priori of the meditation provides the text with prescriptive power to transform the self. Then I study the Méditations chrétiennes et métaphysiques i-iv : we see that Malebranche set his textual apparatus so that it prescribes its receiver a form of « work-on-one’s-self ». The self is here produced by the organisation of relationship between attentive vision and lighting action, and this structure is built in the self by a movement, induced by the text, which leads the self from

  17. A systematic review of socio-economic assessments in support of coastal zone management (1992-2011).

    Le Gentil, Eric; Mongruel, Rémi

    2015-02-01

    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.

    I review recent attempts to construct a local quantum field theory of small violations of the Pauli exclusion principle and suggest a qualitative reason for the surprising rigidity of the Pauli principle. I suggest that small violations can occur in our four-dimensional world as a consequence of the compactification of a higher-dimensional theory in which the exclusion principle is exactly valid. I briefly mention a recent experiment which places a severe limit on possible violations of the exclusion principle. (orig.)

    Social exclusion is a concept that has been widely debated in recent years; a particular focus of the discussion has been its significance in relation to health. The meanings of the phrase "social exclusion", and the closely associated term "social inclusion", are contested in the literature. Both of these concepts are important in relation to health and the area of primary healthcare in particular. Thus, several tools for the measurement of social exclusion or social inclusion status in health care settings have been developed. A scoping review of the peer-reviewed and grey literature was conducted to examine tools developed since 2000 that measure social exclusion or social inclusion. We focused on those measurement tools developed for use with individual patients in healthcare settings. Efforts were made to obtain a copy of each of the original tools, and all relevant background literature. All tools retrieved were compared in tables, and the specific domains that were included in each measure were tabulated. Twenty-two measurement tools were included in the final scoping review. The majority of these had been specifically developed for the measurement of social inclusion or social exclusion, but a small number were created for the measurement of other closely aligned concepts. The majority of the tools included were constructed for engaging with patients in mental health settings. The tools varied greatly in their design, the scoring systems and the ways they were administered. The domains covered by these tools varied widely and some of the tools were quite narrow in the areas of focus. A review of the definitions of both social inclusion and social exclusion also revealed the variations among the explanations of these complex concepts. There are several definitions of both social inclusion and social exclusion in use and they differ greatly in scope. While there are many tools that have been developed for measuring these concepts in healthcare settings, these

But this teratology is not above all clinical but social and moral: he warns us, by this distance from gender, from a moral corruption of the world both by a clinical semiology and ovidian mythology not looking for the pathological realism but the antic filiation with Theophrast’s Characters : philosopher more than naturalist.

    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

    2004-10-07

    This scientific analysis provides retardation factors for colloids transporting in the saturated zone (SZ) and the unsaturated zone (UZ). These retardation factors represent the reversible chemical and physical filtration of colloids in the SZ. The value of the colloid retardation factor, R{sub col} is dependent on several factors, such as colloid size, colloid type, and geochemical conditions (e.g., pH, Eh, and ionic strength). These factors are folded into the distributions of R{sub col} that have been developed from field and experimental data collected under varying geochemical conditions with different colloid types and sizes. Attachment rate constants, k{sub att}, and detachment rate constants, k{sub det}, of colloids to the fracture surface have been measured for the fractured volcanics, and separate R{sub col} uncertainty distributions have been developed for attachment and detachment to clastic material and mineral grains in the alluvium. Radionuclides such as plutonium and americium sorb mostly (90 to 99 percent) irreversibly to colloids (BSC 2004 [DIRS 170025], Section 6.3.3.2). The colloid retardation factors developed in this analysis are needed to simulate the transport of radionuclides that are irreversibly sorbed onto colloids; this transport is discussed in the model report ''Site-Scale Saturated Zone Transport'' (BSC 2004 [DIRS 170036]). Although it is not exclusive to any particular radionuclide release scenario, this scientific analysis especially addresses those scenarios pertaining to evidence from waste-degradation experiments, which indicate that plutonium and americium may be irreversibly attached to colloids for the time scales of interest. A section of this report will also discuss the validity of using microspheres as analogs to colloids in some of the lab and field experiments used to obtain the colloid retardation factors. In addition, a small fraction of colloids travels with the groundwater without any significant

    Social exclusion has a profound emotional impact on children. However, there is still limited and partly conflicting experimental evidence for the possible effect of social exclusion on children's cognitive performance. In the present study, we tested the possibility that some children are more vulnerable than others to the negative effects of social exclusion on cognitive performance. We selected 4 potential candidates that could moderate the effects of social exclusion: relational self-esteem, peer ratings of popularity, rejection sensitivity and nonverbal intelligence. Individual differences in these 4 potential moderating factors were first assessed in a sample of 318 children (45.6 % females; mean age = 9.92 years). Then, in a subsequent experimental session, the participants were either socially included or excluded using a typical manipulation (i.e., the Cyberball paradigm). Following the manipulation, the children's cognitive performance was assessed using a logical reasoning test. The results showed that the children with lower scores for relational self-esteem (the bottom 37.46 % of the sample), lower popularity (43.49 %) or weaker nonverbal intelligence (37.80 %) performed worse on the logical reasoning test following social exclusion. Moreover, children with combined low self-esteem, popularity and nonverbal intelligence were the most affected by social exclusion. This study identified factors that make some children more vulnerable to the negative effects of social exclusion. Overall, the present work underscores the value of considering basic cognitive and relational individual differences when developing interventions aimed at preventing the negative effects of social exclusion among children.

    2016-06-14

    The work analyzes different aspects related to alcohol consumption among homeless people and people at risk of social exclusion. The data was gathered from a representative sample of homeless people in Madrid (n = 188) and a sample of people at risk of social exclusion (n = 164) matched in sex, age, and origin (Spaniards vs. foreigners). The results showed that homeless people present a greater consumption of alcohol and have experienced more problems derived from its consumption than people at risk of social exclusion. Most of the homeless people who had alcohol-related problems had had them prior to their homelessness, and they stated they had poorer health and had experienced a greater number of homelessness episodes. Despite the relevance of problems related to alcohol among our sample, only a small percentage of the sample had participated in treatment programs for alcohol consumption.

    2014-12-01

    Full Text Available OBJECTIVE To assess the determinants of exclusive breastfeeding abandonment. METHODS Longitudinal study based on a birth cohort in Viçosa, MG, Southeastern Brazil. In 2011/2012, 168 new mothers accessing the public health network were followed. Three interviews, at 30, 60, and 120 days postpartum, with the new mothers were conducted. Exclusive breastfeeding abandonment was analyzed in the first, second, and fourth months after childbirth. The Edinburgh Postnatal Depression Scale was applied to identify depressive symptoms in the first and second meetings, with a score of ≥ 12 considered as the cutoff point. Socioeconomic, demographic, and obstetric variables were investigated, along with emotional conditions and the new mothers’ social network during pregnancy and the postpartum period. RESULTS The prevalence of exclusive breastfeeding abandonment at 30, 60, and 120 days postpartum was 53.6% (n = 90, 47.6% (n = 80, and 69.6% (n = 117, respectively, and its incidence in the fourth month compared with the first was 48.7%. Depressive symptoms and traumatic delivery were associated with exclusive breastfeeding abandonment in the second month after childbirth. In the fourth month, the following variables were significant: lower maternal education levels, lack of homeownership, returning to work, not receiving guidance on breastfeeding in the postpartum period, mother’s negative reaction to the news of pregnancy, and not receiving assistance from their partners for infant care. CONCLUSIONS Psychosocial and sociodemographic factors were strong predictors of early exclusive breastfeeding abandonment. Therefore, it is necessary to identify and provide early treatment to nursing mothers with depressive symptoms, decreasing the associated morbidity and promoting greater duration of exclusive breastfeeding. Support from health professionals, as well as that received at home and at work, can assist in this process.

In two cases, severe stent retraction during deployment necessitated placement of an additional stent. Immediately after stent placement, a marked reduction of flow within the sac was observed in all cases (peri-interventional mortality 0 %). During FU, there were two thrombotic stent occlusions, making reintervention necessary (primary patency rate 80 %, secondary patency 100 %). Four IAA were completely occluded at FU, whereas the original vessel and covered branches (n = 8) were patent. In four IAA, there was still residual perfusion. In one patient, IAA diameter decreased slightly, while it remained constant in seven (mean imaging FU 195 (range 1-695) days). There were no adverse events on clinical FU (mean FU 467 (range 101-695) days).ConclusionsOther studies showed the Cardiatis-Multilayer-Stent to be a technically relatively simple treatment option for complex IAA with inadequate landing zones, especially in patients with multiple comorbidities to avoid ipsilateral IIA obstruction. However, in our series complication rate was high. Incomplete sac exclusion, stent-shortening, and thrombotic occlusion can complicate treatment, making meticulous patient selection necessary. Close imaging surveillance is mandatory especially in the early postinterventional period.

  11. Fuel conditioning facility zone-to-zone transfer administrative controls

    Pope, C. L.

    2000-01-01

    The administrative controls associated with transferring containers from one criticality hazard control zone to another in the Argonne National Laboratory (ANL) Fuel Conditioning Facility (FCF) are described. FCF, located at the ANL-West site near Idaho Falls, Idaho, is used to remotely process spent sodium bonded metallic fuel for disposition. The process involves nearly forty widely varying material forms and types, over fifty specific use container types, and over thirty distinct zones where work activities occur. During 1999, over five thousand transfers from one zone to another were conducted. Limits are placed on mass, material form and type, and container types for each zone. Ml material and containers are tracked using the Mass Tracking System (MTG). The MTG uses an Oracle database and numerous applications to manage the database. The database stores information specific to the process, including material composition and mass, container identification number and mass, transfer history, and the operators involved in each transfer. The process is controlled using written procedures which specify the zone, containers, and material involved in a task. Transferring a container from one zone to another is called a zone-to-zone transfer (ZZT). ZZTs consist of four distinct phases, select, request, identify, and completion

  15. Layer 6 cortical neurons require Reelin-Dab1 signaling for cellular orientation, Golgi deployment, and directed neurite growth into the marginal zone.

    2012-07-07

    The secreted ligand Reelin is believed to regulate the translocation of prospective layer 6 (L6) neocortical neurons into the preplate, a loose layer of pioneer neurons that overlies the ventricular zone. Recent studies have also suggested that Reelin controls neuronal orientation and polarized dendritic growth during this period of early cortical development. To explicitly characterize and quantify how Reelin controls this critical aspect of neurite initiation and growth we used a new ex utero explant model of early cortical development to selectively label a subset of L6 cortical neurons for complete 3-D reconstruction. The total neurite arbor sizes of neurons in Reelin-deficient (reeler mutant) and Dab1-deficient (Reelin-non-responsive scrambler mutant) cortices were quantified and unexpectedly were not different than control arbor lengths (p = 0.51). For each mutant, however, arbor organization was markedly different: mutant neurons manifested more primary processes (neurites emitted directly from the soma) than wild type, and these neurites were longer and displayed less branching. Reeler and scrambler mutant neurites extended tangentially rather than radially, and the Golgi apparatus that normally invests the apical neurite was compact in both reeler and scrambler mutants. Mutant cortices also exhibited a neurite "exclusion zone" which was relatively devoid of L6 neuron neurites and extended at least 15 μm beneath the pial surface, an area corresponding to the marginal zone (MZ) in the wild type explants. The presence of an exclusion zone was also indicated in the orientation of mutant primary neurite and neuronal somata, which failed to adopt angles within ~20˚ of the radial line to the pial surface. Injection of recombinant Reelin to reeler, but not scrambler, mutant cortices fully rescued soma orientation, Golgi organization, and dendritic projection defects within four hrs. These findings indicate Reelin promotes directional dendritic growth into

    Prostate tumors arise primarily in the peripheral zone (PZ) of the prostate, but 20–30% arise in the transition zone (TZ). Zone of origin may have prognostic value or reflect distinct molecular subtypes; however, it can be difficult to determine in practice. Using whole-genome gene expression, we built a signature of zone using normal tissue from five individuals and found that it successfully classified nine tumors of known zone. Hypothesizing that this signature captures tumor zone of origin, we assessed its relationship with clinical factors among 369 tumors of unknown zone from radical prostatectomies (RPs) and found that tumors that molecularly resembled TZ tumors showed lower mortality (P = 0.09) that was explained by lower Gleason scores (P = 0.009). We further applied the signature to an earlier study of 88 RP and 333 transurethral resection of the prostate (TURP) tumor samples, also of unknown zone, with gene expression on ~6000 genes. We had observed previously substantial expression differences between RP and TURP specimens, and hypothesized that this might be because RPs capture primarily PZ tumors, whereas TURPs capture more TZ tumors. Our signature distinguished these two groups, with an area under the receiver operating characteristic curve of 87% (P zones. Zone of origin may be important to consider in prostate tumor biomarker research. PMID:25870172

  18. Social exclusion of older persons: a scoping review and conceptual framework.

    2017-03-01

    As a concept, social exclusion has considerable potential to explain and respond to disadvantage in later life. However, in the context of ageing populations, the construct remains ambiguous. A disjointed evidence-base, spread across disparate disciplines, compounds the challenge of developing a coherent understanding of exclusion in older age. This article addresses this research deficit by presenting the findings of a two-stage scoping review encompassing seven separate reviews of the international literature pertaining to old-age social exclusion. Stage one involved a review of conceptual frameworks on old-age exclusion, identifying conceptual understandings and key domains of later-life exclusion. Stage two involved scoping reviews on each domain (six in all). Stage one identified six conceptual frameworks on old-age exclusion and six common domains across these frameworks: neighbourhood and community; services, amenities and mobility; social relations; material and financial resources; socio-cultural aspects; and civic participation. International literature concentrated on the first four domains, but indicated a general lack of research knowledge and of theoretical development. Drawing on all seven scoping reviews and a knowledge synthesis, the article presents a new definition and conceptual framework relating to old-age exclusion.

    Adding a new entity to an organization's existing insurance program can be problematic if the existing policy contains a known prior acts exclusion clause. By purportedly excluding claims that a policyholder "could have reasonably foreseen or discovered," the known prior acts exclusion allows the insurer to reject those claims after a lawsuit has been filed policyholders should have known prior acts exclusion clauses removed from their policies or work with their insurers on language that will clarify the policy regarding this exclusion.

    Very little population-based research has been conducted around the exclusive breastfeeding practices of Inuit Canadians. This research aims to assess the distribution of exclusive breastfeeding among Inuit Canadians and to identify factors associated with exclusive breastfeeding as recommended. We use data from 188 infant-mother dyads who completed the Nunavut Inuit Child Health Survey, a cross-sectional, population-based survey of Inuit children aged 3 to 5 years. A series of multinomial logistic regression models were run to identify factors associated with 4 exclusive breastfeeding durations (≤ 1 month, > 1- 6.5 months). Of infants, 23% were exclusively breastfed as recommended (ie, between 5.5 and 6.5 months; 95% CI, 16.2-29.3). Many infants (61%) were exclusively breastfed for less than 5.5 months and 16% (95% CI, 10.9-22.0) were exclusively breastfed for more than 6.5 months. Families receiving income support were less likely to discontinue exclusive breastfeeding before 5.5 months (pOR1- Inuit Canadian infants receive suboptimal exclusive breastfeeding. National, provincial, and community-specific interventions to protect, promote, and support exclusive breastfeeding should emphasize not only the benefits of exclusively breastfeeding to 6 months but also the importance of timely introduction of complementary foods into the infant's diet.

    No research, to date, has investigated the role of ethnic school composition (and intergroup contact) on European-American youth’s use of stereotypes to explain interracial discomfort in the context of peer exclusion. In this study European-American 4th, 7th and 10th grade students (N = 414), attending low and high ethnically diverse public schools (with low and high self-reports of cross-race/ethnic friendships, respectively) evaluated three contexts of interracial exclusion (at lunch time, at a school dance, and at a sleepover). In addition to age and context effects, participants enrolled in high diversity schools were less likely to use stereotypes to explain racial discomfort, more likely to view racial exclusion as wrong, and more likely to estimate that racial exclusion occurs, than were participants enrolled in low diversity schools. These findings have implications for the role of social experience on racial attitudes and judgments about exclusion. PMID:25328425

    One of the fundamental rules of nature and a pillar in the foundation of quantum theory and thus of modern physics is represented by the Pauli Exclusion Principle. We know that this principle is extremely well fulfilled due to many observations. Numerous experiments were performed to search for tiny violation of this rule in various systems. The experiment VIP at the Gran Sasso underground laboratory is searching for possible small violations of the Pauli Exclusion Principle for electrons leading to forbidden X-ray transitions in copper atoms. VIP is aiming at a test of the Pauli Exclusion Principle for electrons with high accuracy, down to the level of 10 −29 – 10 −30 , thus improving the previous limit by 3–4 orders of magnitude. The experimental method, results obtained so far and new developments within VIP2 (follow-up experiment at Gran Sasso, in preparation) to further increase the precision by 2 orders of magnitude will be presented

    Full Text Available Background: The elderly are considered as one of the vulnerable groups as they are subjected to the risk of decrease of participation in different domains of their life due to losing their jobs, a drop in salary and the increase of health-related problems. The current research was aimed to seek the elderly social exclusion domains in various countries around the world. Methods: This systematic review analyzed the published studies from 1999 to 2013. The articles were searched using the keywords of social exclusion along with old people, aging, elderly both in Persian and English in Google search engine and the Iranian and international databases. From among 77 studies obtained, 16 studies met the inclusion criteria for this research. Results: the findings indicated that the majority of studies (9 were conducted in Britain and the most common logical model was distributional and relational approach. Indicators were categorized in 5 domains: economic, social, health, environmental and neighborhood, and discrimination and elderly-oriented. In 50 percent of studies, access or lack of access to services, civil participations and social relations, in 12.5 percent of studies, access to proper health and in 18.7 percent of studies, living in secure environment and neighborhood were the indicators which attracted the most attention in evaluating the elderly social exclusion. Conclusion: Generally, choosing a logical and proper model to design and evaluate social exclusion contributed to decreasing the problems of social exclusion evaluation. Using the data gathered in family panels can also facilitate access to the data related to periodical evaluation of social exclusion.

    Casino exclusion programs are intended to prevent or limit gambling-related harm. Although previous research showed that self-exclusion is associated with reduced gambling, it remains unknown whether self- and forced excluded subjects show different patterns of gambling behavior and if exclusion from casino gambling affects all gambling activities. The present study retrospectively investigated (1) the role of voluntariness of exclusion for the first time, and (2) general gambling behavior of excluded individuals before and after exclusion. A total of N = 215 casino excluders (self-excluders: n = 187, forced excluders: n = 28) completed an online survey or a face-to-face interview up to 8 years after enrollment. Self- and forced excluders showed similar rates of abstinence (self-excluders: 19.3%, forced excluders: 28.6%) and reduction (self-excluders: 67.4%, forced excluders: 60.7%), even though forced excluders reported a significantly greater initial gambling intensity compared to self-excluders (e.g., pre-exclusion gambling time; self-excluders: 3.2 days/week, forced excluders: 4.3 days/week). Overall, results indicated that 20.5% of excluders stopped all gambling activities and another 66.5% reduced their gambling. Those who continued gambling significantly reduced this behavior in every segment, except for gambling halls. Findings indicate that self- and forced exclusion are associated with similarly reduced gambling behavior, even in non-excluded segments. However, unchanged gambling in gambling halls emphasizes the importance to implement consistent exclusion programs over all gambling segments.

  13. Effect of the waste exclusion distance on the postclosure performance of a reference disposal system

    International Nuclear Information System (INIS)

    Goodwin, B.W.; Hajas, W.C.; Melnyk, T.W.; Kitson, C.I.

    1995-07-01

    The concept for disposal of Canada's nuclear fuel waste involves the isolation of the waste in corrosion-resistant containers placed in a sealed vault at a depth of 500 to 1000 metres in plutonic rock of the Canadian Shield. The technical feasibility of this concept, and its impact on the environment and human health, are summarized in an Environmental Impact Statement (EIS). The EIS is supported by nine primary references, one of which describes the postclosure assessment of the concept. The postclosure assessment is concerned with the long-term performance and behaviour of the disposal system, starting from the time the disposal facility is closed and extending far into the future. The discussions presented in the EIS and the postclosure assessment are based on a case study of a hypothetical disposal system with specific design features and host rock characteristics. The design features are founded on a conceptual engineering study and the rock characteristics are derived from geological studies of a field research area. In the case study, the long-term performance of the hypothetical disposal system was strongly dependent on a design parameter called the waste exclusion distance. This distance is defined as the minimum length of low-permeability sparsely fractured rock between the waste-emplacement part of the hypothetical vault and a nearby conductive fracture zone in the host rock. In this report, we examine trends in estimates of radiological impact as a function of the waste exclusion distance. (author). 18 refs., 14 figs

    2016-05-01

    Full Text Available Background Breast milk is the ideal food for infants. According to the 2007 Indonesian National Household Health Survey, only 23% of mothers exclusively breastfeed for six months. Objectives To determine the rate of exclusive breastfeeding in Indonesia, to evaluate factors associated with infant feeding practices, and to compare the nutritional and developmental status between exclusively-breastfed and formula-fed infants. Methods A survey was conducted in hospitals located in 17 provinces in Indonesia. The rate of exclusive breastfeeding was calculated. Many variables were investigated as potential predictors for exclusive breastfeeding using a multivariable logistic regression analysis. Further analysis was performed to compare the nutritional and developmental status between exclusively breastfed and formula-fed infants at the time of survey. Results From 1,804 infant subjects, the overall rate of exclusive breastfeeding was 46.3%, ranging from 10.5% in East Java to 66.9% in Jambi. Predominant breastfeeding, complementary feeding, and formula feeding rates were 14.3%, 8.6%, and 30.7%, respectively. Maternal unemployment was associated with a longer duration of breastfeeding (P=0.000. There were significantly more formula-fed infants who were undernourished compared to exclusively-breastfed infants (14% vs. 8%, P=0.001. There were also significantly more infants in the formula-fed group who had abnormal head circumference compared to those in the exclusively-breastfed group (9% vs. 6%, P=0.031. Child development, as assessed by the Pre-screening Developmental Questionnaire, was similar between the two groups (P=0.996. Conclusion The overall rate of exclusive breastfeeding in Indonesia is 46.3%. Maternal unemployment is associated with longer duration of breastfeeding. Exclusive breastfed infants have significant better growth and head circumference compared to formula fed infants, while the development is similar between the two groups.

  17. The ADS/QCD correspondence and exclusive processes

    International Nuclear Information System (INIS)

    Brodsky, Stanley J.; De Teramond, Guy F.; Deur, Alexandre

    2011-01-01

    The AdS/CFT correspondence between theories in AdS space and conformal field theories in physical space-time provides an analytic, semi-classical, color-confining model for strongly-coupled QCD. The soft-wall AdS/QCD model, modified by a positive-sign dilaton metric, leads to a remarkable one-parameter description of nonperturbative hadron dynamics at zero quark mass, including a zero-mass pion and meson and baryon Regge spectra of linear trajectories with the same slope in orbital angular momentum L and radial quantum number n. One also predicts the form of the non-perturbative effective coupling alpha AdS/s (Q) and its Beta-function which agrees with the effective coupling alphag1 extracted from the Bjorken sum rule. Light-front holography, which connects the fifth-dimensional coordinate of AdS space z to an invariant impact separation variable zeta, allows one to compute the analytic form of the frame-independent light-front wave functions, the fundamental entities which encode hadron properties as well as decay constants, form factors, deeply-virtual Compton scattering, exclusive heavy hadron decays, and other exclusive scattering amplitudes. One thus obtains a relativistic description of hadrons in QCD at the amplitude level with dimensional counting for exclusive reactions at high momentum transfer. As specific examples, we discuss the behavior of the pion and nucleon form factors in the space-like and time-like regions. We also review the phenomenology of exclusive processes including some anomalous empirical results.

Tandis qu’au XVIIe siècle (et encore chez plusieurs auteurs du XVIIIe, le plaisir est décrit comme une expérience dont le lieu principal est la sociabilité, à l’inverse de la méditation sise de préférence dans la solitude, le XVIIIe siècle réinscrit le plaisir dans l’intimité solitaire du moi et majore l’idée d’une nécessaire communauté des sujets connaissant. La caractérisation kantienne de l’expérience esthétique, comme expérience d’un plaisir qui enveloppe immédiatement une prétention à l’universalité et à la communication, apparaît dès lors comme une façon de rompre la logique de ce chiasme.

    Dans un contexte constructiviste, les connaissances anterieures d'un individu sont essentielles a la construction de nouvelles connaissances. Quelle qu'en soit la source (certaines de ces connaissances ont ete elaborees en classe, d'autres ont ete elaborees par interaction personnelle de l'individu avec son environnement physique et social), ces connaissances, une fois acquises, constituent les matieres premieres de l'elaboration des nouvelles conceptions de cet individu. Generalement, cette influence est consideree comme positive. Cependant, dans un milieu scolaire ou l'apprentissage de certaines conceptions enchassees dans un programme d'etudes et enterinees par l'ensemble d'une communaute est obligatoire, certaines connaissances anterieures peuvent entraver la construction des conceptions exigees par la communaute. La litterature abonde de tels exemples. Cependant, certaines connaissances anterieures, en soi tout a fait conformes a l'Heritage, peuvent aussi, parce qu'utilisees de facon non pertinente, entraver la construction d'une conception exigee par la communaute. Ici, la litterature nous donne peu d'exemples de ce type, mais nous en fournirons quelques-uns dans le cadre theorique, et ce sera un d'entre eux qui servira de base a nos propos. En effet, une grande proportion d'eleves inscrits a un cours de sciences physiques de la quatrieme secondaire, en reponse a un probleme deja solutionne durant l'annee et redonne lors d'un examen sommatif, "Pourquoi la Lune nous montre-t-elle toujours la meme face?", attribue principalement la cause de ce phenomene a la rotation de la Terre sur son axe. En tant que responsable de l'enseignement de ce programme d'etudes, plusieurs questions nous sont venues a l'esprit, entre autres, comment, dans un contexte constructiviste, est-il possible de reduire chez un eleve, l'impact de cette connaissance anterieure dans l'elaboration de la solution et ainsi prevenir la construction d'une conception erronee? Nous avons teste nos
