  1. International Uranium Resources Evaluation Project (IUREP) national favourability studies: Luxembourg

    1977-12-01

    The Grand Duchy of Luxembourg is a tiny, roughly triangular, sovereign state situated in Western Europe and bordered by Belgium, the Federal Republic of Germany and Prance. Its total surface area is 998 sq. miles (2,586 sq. kilometres). Its situation in Europe has made it a natural crossroads, with its language, economic interests and ways of life reflecting its close association with its neighbours. It has, however, remained a separate, if not always autonomous, political unit since the tenth century. It is one of the nine member states of the European Economic Community. The country is made up of an elevated northern tableland and a southern lower plateau. The northern section comprises part of the Ardennes mountains which continue in south-east Belgium and form a plateau generally ranging between 1,000 and 2,000 feet. Iron ore mines are located near the French border. The southern section has an elevation of below 15,000 feet and comprises mainly heavily wooded good agricultural land. There has been virtually no work done; no uranium occurrences of significance are recorded. No specific exploration for uranium in Luxembourg is apparent at the present. There are no specific regulations relating to uranium exploration,which is covered by the rules relating to mineral exploration in general

  2. Luxembourg.

    1987-04-01

    The population of Luxembourg stood at 366,000 in 1986, with an annual growth rate of under 1%. The infant mortality rate is 11.7/1000. Life expectancy is 70 years for men and 76.7 years for women. There is 100% literacy. Luxembourg's gross domestic product in 1986 was US$5.1 billion, with an annual growth rate of 2.5% and a per capita income of $13,900. Of the labor force of 161,000, 5% are engaged in agriculture, 35% are employed in industry and commerce, 49% work in services, and 11% are employed by the government. Luxembourg has a parliamentary form of government with a constitutional monarchy. The 3 major parties are the Christian Social Party, the Socialist Party, and the Democratic (Liberal) Party. Luxembourg is a highly industrialized, export-intensive country. The iron and steel sector is the most important single sector of the economy; steel accounts for 36% of all exports, 10% of the gross domestic product, and 9% of the work force. The recent relative decline of the steel sector has been offset by the development of Luxembourg as a financial center. In 1987, the government estimates that unemployment will remain below 1.8%, inflation will increase slightly to 2%, and the gross domestic product's growth will increase to 2.8%.

  3. [Suicide in Luxembourg: a statistical study].

    1983-01-01

    A review of the situation concerning suicide in Luxembourg is presented. The existing laws are first described, and some methodological questions are summarized. A statistical analysis of suicide in the country is then presented. Data are included on trends over time, 1881-1982; and on variations in suicide by sex, age, marital status, religion, nationality, and occupation and standard of living. A bibliography is also provided.

    Rohstock, Anne; Schreiber, Catherina

    2013-01-01

    Since Luxembourg became independent in 1839, practically the entire political, economic and intellectual elite of the country has been socialised abroad. It was only in 2003 that the Grand Duchy set up its own university; before then, young Luxembourgers had to study in foreign countries. Over the past 150 years, Luxembourg has thus experienced…

    2012-10-11

    No previous study has examined the prevalence of cardiovascular risk factors and explored the influence of immigration status and acculturation on overweight/obesity among the Portuguese immigrants to Luxembourg. Our objectives were to (1) compare the prevalence of cardiovascular risk factors between native Luxembourgers and Portuguese immigrants, (2) examine the relationship between immigrant generation status, proportion of life spent in Luxembourg and language proficiency or preference (as proxy variables of acculturation) and overweight/obesity among Portuguese immigrants, and (3) elucidate the role of underlying socioeconomic, behavioral and dietary factors in overweight/obesity differences among the two populations. Recent national cross-sectional data from ORISCAV-LUX survey 2007-2008, composed of 843 subjects were analyzed. Overweight/obesity was defined as body mass index (BMI) >25 kg/m(2). Acculturation score was measured by using immigrant generation status, proportion of life spent in Luxembourg, and language proficiency or preference. Univariable and multivariable logistic regression analyses were performed to examine the association between acculturation markers and overweight/obesity. Further, a series of successive models were fitted to explore the separated and added impact of potential mediators (socioeconomic status, physical activity, dietary factors) on overweight/obesity among Luxembourgers and Portuguese immigrants. Compared to Luxembourgers, Portuguese immigrants of first and second generation were younger and currently employed. About 68% of first generation Portuguese had only primary school, and about 44% were living below poverty threshold. Although the cardiovascular risk factors were comparable, Portuguese immigrants were more frequently overweight and obese than Luxembourgers, even after age and gender standardization to the European population. Overweight/obesity was significantly higher among Portuguese of first generation compared

  9. Living arrangements of young adults living independently: evidence from the Luxembourg Income Study.

    Short, K S; Garner, T I

    1990-12-01

    A cross-country comparison of the impact of socioeconomic factors on household formation by young adults in the 15-24 age group is presented. "Of those young people living independently (not in their parental homes), how do incomes from various sources affect their decision whether to live alone or with others? The sample did not include all persons in the 15-24 age group, only those living independently. A logit analysis of the living alone question was conducted using data from five countries (Canada, the Federal Republic of Germany, the United Kingdom, Australia, and the United States) included in the LIS [Luxembourg Income Study] data base to determine whether differences across countries exist." excerpt

  10. Income inequality and educational assortative mating: Evidence from the Luxembourg Income Study.

    Monaghan, David

    2015-07-01

    Though extensive research has explored the prevalence of educational assortative mating, what causes its variation across countries and over time is not well understood. Using data from the Luxembourg Income Study Database, I investigate the hypothesis that assortative mating by income is influenced by income inequality between educational strata. I find that in countries with greater returns to education, the odds of any sort of union that crosses educational boundaries is substantially reduced. However, I do not find substantial evidence of an effect of changes in returns to education on marital sorting within countries. Educational and labor market parity between males and females appear to be negatively related to marital sorting. Copyright © 2015 Elsevier Inc. All rights reserved.

  12. International Uranium Resources Evaluation Project (IUREP) national favourability studies: Indonesia

    1977-10-01

    Indonesia is a country of south east Asia comprising a large island group extending east-west for over 3000 miles. The geology of Indonesia is fairly well known but is extremely complicated. Successive mountain movements took place around an ancient crustal area. The oldest, of Permian-Triassic age formed northeast Sumatra, northern Java and western Kalimantan. This was followed by the Sumatra orogenesis and finally in Cretaceous and Tertiary times the southern half of Java and the islands as far as New Guinea were formed. Geological studies tend to indicate that the most favourable uranium areas are likely to be in West Sumatra and West Kalimantan. Exploration by the Directorate of Survey and Geology of the National Atomic Energy Agency has been carried out on a small scale since 1961. Exploration concession have been granted to French, German and Japanese organisations. No uranium reserve or resource figures have ever been stated but small occurrences and radioactive anomalies have been found in West and South Sumatra, West and Central Kalimantan and in West Irian. Although the geology of some areas appears to be favourable, little success has attended exploration efforts to date and thus the Speculative Potential is noted as between 1,000 and 10,000 tonnes uranium.

    1977-10-01

    There is no information on production of nuclear raw materials in Burma, although there are some uranium occurrences. Hunting Geophysics Ltd has done some aerial prospecting work in the area of Victoria Point in Southern Burma. All the data collected has been plotted on several maps and issued to various Burmese organizations, with a complete report. The follow-up ground exploration was done by a prospecting party headed by Dr Gjelsvik. The Hunting Geophysics' and Dr Gjelsvik reports are not available in the IAEA. The Raw Materials Division in the Union of Burma Atomic Energy Center commenced operations in 1955. The area of Mogok was selected by U Soo Win, the head of the Division, as most favourable for uranium exploration. The region is mountainous, with heavy forest cover. A ground gamma-ray survey was carried out in Mogok Mineral Belt by two geologists accompanied by two assistants, at a spacing of one km. This work showed monazite in all streams over an area of about 150 sq km and has given a detailed studies led to the discovery of some uraninite and pitchblende in the overburden of an old lode. Based, on these first discoveries the Government of Burma requested assistance from the IAEA and an expert was sent there for a period of one year. His field work was mainly limited in the Mogok Mineral Belt, however some reconnaissance field trips were made in other parts of the country. Dr D L Searle concluded that the Mogok area represents a zone of high temperature mineralization but a lower temperature form of uranium mineralization may have developed along the outer edges of the principal high grade zone. He recommended that the area between the Mogok scarp and the Shweli River be systematically traversed. Uranium bearing minerals in Burma are the following: monazite bearing beach sands near Amherst, Tenasserim; monazite placers from near Momeik, Northern Shan States; uraninte crystals from the gem-gravels around Mogok; a radioactive anomaly in syenite at

    1977-10-01

    The Federal Republic of Austria is situated in the southeastern part of Central Europe. The country covers a total area of 83.350 square kilometers, the population amounts to 7.5 million inhabitants. The geographical features of Austria are dominated by the E-W-trending chain of the Alps (approximately 60% of the country). The northeastern part of the country is formed by the nonalpine mountains and hills of the Bohemian Massif. There are a large depression, the basin of Vienna, as well as parts of the Pannonian basin in the eastern part. The main hydrographic features are characterized by the river Danube and its tributaries. With the exception of a small part in the west of the country, the drainage system of which is directed to the river Rhine, all other rivers are drained by the Danube. The elevations in the Alps reach heights of up to 3 800 m. Many of the E-W striking mountain chains are higher than 2000 to 2500 m. Several major N-S trending passes over the mountains are favourable for the transportation systems (railroads, motorroads) - The kind of land use in Austria is mainly determined by the character of the landscape which is made up of mountains and valleys as well as of depressions in the eastern part of the country. In the lowlands, good farmland is available. At lower and at medium elevations, forests and grassland predominate in the Alps. At higher elevations, the Alps are covered with grasslands; a great part of the rocks has no soil cover, another part is covered by perennial snow and ice.The presence of many uranium occurrences in the Permo-Triassic sediments justifies a detailed survey of these strata. Special studies on the lithology and the formation of uranium in these rocks have been made during the last few years. They should be evaluated to point out new favourable prospective areas. The potential of Uranium which is assumed to be found in Austria is 10,000 - 50,000 t U

  16. The Impact of the Basel III Liquidity Regulations on the Bank Lending Channel: A Luxembourg case study

    2011-01-01

    In this paper we study the impact of the Basel III liquidity regulations, namely the Liquidity Coverage Ratio (LCR) and the Net Stable Funding Ratio (NSFR), on the bank lending channel in Luxembourg. For this aim we built, based on individual bank data, time series of the LCR and NSFR for a sample of banks covering between 82% and 100% of total assets of the banking sector. Additionally, we simulated the optimal balance sheet adjustments needed to adhere to the regulations. We extend the exis...

  19. Dissolved and particulate nutrient export from rural catchments: a case study from Luxembourg.

    Salvia-Castellví, Mercè; Iffly, Jean François; Borght, Paul Vander; Hoffmann, Lucien

    2005-05-15

    Nutrient enrichment of freshwaters continues to be one of the most serious problems facing the management of surface waters. Effective remediation/conservation measures require accurate qualitative and quantitative knowledge of nutrient sources, transport mechanisms, transformations and annual dynamics of different nitrogen (N) and phosphorus (P) forms. In this paper, nitrate (NO3-N), soluble reactive phosphorus (SRP) and total phosphorus (TP) concentrations and loads are presented for two adjacent rural basins of 306 km2 and 424 km2, and for five sub-basins differing in size (between 1 km2 and 33 km2), land use (extent of forest cover between 20% and 93%) and household pressure (from 0 to 40 people/km2) with the aim of studying the influence of land use and catchment size on nutrient exports. The studied catchments are all situated on Devonian schistous substrates in the Ardennes region (Belgium-Luxembourg), and therefore have similar hydrological regimes. As the study period could not be the same for all basins, annual export coefficients were corrected with the 25 years normalized discharge of the Sure River: two regression analyses (for dry and humid periods) relating monthly nutrient loads to monthly runoff were used to determine correction factors to be applied to each parameter and each basin. This procedure allows for the comparing annual export coefficients from basins sampled in different years. Results show a marked seasonal response and a large variability of NO3-N export loads between forested (4 kg N ha-1 year-1), agricultural (27-33 kg N ha-1 year-1) and mixed catchments (17-22 kg N ha-1 year-1). For SRP and TP, no significant agricultural impact was found. Land and bank erosion control the total P massflow in the studied catchments (0.4-1.3 kg P ha-1 year-1), which is mostly in a particulate form, detached and transported during storm events. Soluble reactive P fluxes ranged between 10% and 30% of the TP mass, depending on the importance of point

  20. International Uranium Resources Evaluation Project (IUREP) national favourability studies: Sweden

    1977-11-01

    Sweden, covers an area of approx. 450 000 square kilometers. It has a population of 8 millions. With few exceptions in the northern part the access can be regarded as good. A dense network of motorroads and railroad exists. The results obtained by the exploration works combined with other available geo-information permit a separation of two principal uranium provinces in Sweden. The first one is confined to sediments of Upper Cambrian and Lower Ordovician which appears in Southern Sweden and along the border of the Caledonian mountain range in Central Sweden. The uranium occurrence are stratiform, of blackshale type which occurs in the Peltura zone of Upper Cambrian or they are associated to a phosphatite-bearing unit of Lower Ordovician overlying the Cambrian shale formation. The distribution of uranium in Upper Cambrian rocks is in general dependant on their lithology which itself is related to the paleography. This conditions explain relatively higher uranium content of the shale from Billigen.The potential resources of the province are estimated at about 1 million tonnes uranium. The second uranium province, called Arjeplog-Arvidsjaur, situated immediately south of the Arctic circle, comprises one deposit - Pleutajokk - and a group of more than twenty occurrences of similar characteristics and age (1 700 - 1 800 my.). The results of the past exploration have shown that uranium is present in different types of rocks. Because of the presence of uranium in many of the pegmatites the possibility of the formation of large low grade deposits should be tested. Favourable areas are those regions where the geological conditions are similar to the geology of the Grenville province in Canada or the Damara belt of SW-Africa. Special studies are recommended on this subject

    1977-11-01

    Maldives, an archipelago consisting of between 1,000 and 2,000 islands and atolls in the Indian Ocean contain only 300 square kilometers and is populated by around 130,000 people who are engaged in raising of copra, fruits, taro, and other agricultural products, and in fishing. There is not now and never has been a mining industry except for quarrying of coral road metal. Geologically the coral islands, based on present geological thinking is not a favourable host or source of uranium, and is therefore assigned a zero potential. (author)

  2. International Uranium Resources Evaluation Project (IUREP) national favourability studies: Iran

    1977-12-01

    Iran is on the southern flank of the Alpine-Himalayan mountain system and has within its extensive boundaries rocks ranging from crystalline metamorphics and igneous rocks of Precambrian age to sediments of Tertiary - Pleistocene age, some of which could be considered as potentially favourable for uranium deposits. The search for uranium started about 1959 and in the following years some 40 radioactive anomalies and a small number of uranium occurrences were identified. In 1977 the Atomic Energy Organization of Iran greatly expanded its exploration activities and contracted for 895,000 line kilometres to be flown by three contractors in an aerial spectrometric survey designed to cover almost the two fifths of the whole country. The follow-up of this survey will continue for several years. Purely on the basis of its size (1,648,004 km 2 ), its several favourable host rock areas, its location on the flank of the Alpine-Himalayan system and the relatively small amount of systematic exploration coverage completed to date the Speculative Potential could be placed in the 50,000 - 100,000 tonnes category.

  3. International Uranium Resources Evaluation Project (IUREP) national favourability studies: Philippines

    1976-12-01

    Comparison between the geology of the Philippines and favourable geological environments for uranium in other parts of the world suggests that the Philippine geology is not likely to be favourable for the discovery of uranium. Previous work has been mainly of a reconnaissance type and orientated mainly to checking the existing mining areas for radioactivity. The only occurrence known at the present time is at Larap Mine in the Paracale District of Camarines Norte in Luzon. A magnetite iron ore body operated by Philippines Iron Mines Inc contained certain distinct beds, which, in addition to magnetite also contain copper, molybdenum and iron sulphides and uraninite. It is estimated that 200 short tons U 3 O 8 is contained in 500,000 tons ore grading 0.04% U 3 O 8 at Larap. A number of other largely untested but similar occurrences have also been identified in the Paracale District. A few small occurrences of uranium have recently been identified on the island of Samar. It is suggested that the Speculative Potential of the Philippines may be of the order of 1000 tonnes U 3 O 8 . (author)

  4. International Uranium Resources Evaluation Project (IUREP) national favourability studies: Thailand

    1977-08-01

    Thailand is a country with an area of 514?000 square kilometres situated in the centre of continental south-east Asia, The geology of Thailand is very varied with sedimentary formations ranging from Cambrian to Quaternary in age and including sandstones, shales, limestones of many varieties. Among the igneous rocks, granites are very important and rhyolites, tuffs diorites, basalts and ultrabasic rocks also exist. Tin is the most important mineral occurrence. Available information on the geology and mineral resources suggests that the country may contain significant resources of radioactive minerals. Favourable potential host types are; 1) uranium and thorium in monazite in beach sands and tin placer deposits; 2) uranium in sandstones, principally in Jurassic sandstones of the Khorat Plateau; 3) uranium in Tertiary lignite deposits; 4) uranium in veins in granites; 5) uranium related to fluorite deposits; 6) uranium in black shales and phosphates. Uranium mineralization in sedimentary rocks at Phu Wieng was discovered in 1970. The area has been radiometrically grid mapped and limited shallow drilling has shown continuity.of the narrow, carbonaceous, conglomeratic sandstone host bed. No uranium reserves or resources can be stated at the present time, but the favourable geology of the Khorat Plateau, the known uranium occurrence and the very small exploration coverage is possibly indicative of a good future potential. The Speculative Potential is estimated to be between 1000 and 10,000 tonnes uranium. (author)

  5. International Uranium Resources Evaluation Project (IUREP) national favourability studies: Israel

    1977-12-01

    The geology of Israel is relatively simple. Most of the country is underlain by sedimentary rocks of Secondary and Tertiary age. As far as the IAEA is aware no systematic exploration has been done for conventional type uranium deposits. Israel has no uranium deposits, and no high or low-grade uranium ores. However, there are uranium 'sources' which are mainly phosphate rock.Proven phosphate reserves in Israel are estimated at about 220 million tons in five different locations. The average uranium concentration is between 100 and 170 ppm. This makes the uranium content in the proven phosphate reserves of Israel to be about 25,000 tons. Together with the possibility of additional discoveries and on the assumption that the economic conditions for the production of both phosphate and uranium become favourable the Speculative Potential is placed in the 10,000 to 50,000 tonnes uranium category.

  6. International Uranium Resources Evaluation Project (IUREP) national favourability studies: Iraq

    1977-11-01

    Iraq consists of a lowland trough lying between asymmetrical and very different upland massifs to the east, north and west and continuing southeastwards to the Persian Gulf. The region is one of crustal weakness and subsidence with relatively young plastic sedimentary rocks engulfed in downwarped, ancient, rigid and highly resistant blocks. Exploration in the 1954-55 period found some minor radioactive anomalies and very low uranium contents in limestones and phosphates. The results of an aerial radiometric survey in 1973-74 are not known to IAEA. Iraq has no reported uranium resources but there are several favourable formations which warrant a detailed survey. In view of the size of the country and the small amount of systematic exploration carried out up to the present time, the Speculative Potential is considered to lie in the 1,000 to 10,000 tonnes uranium category.

  7. International Uranium Resources Evaluation Project (IUREP) national favourability studies: Bangladesh

    1978-01-01

    With the exception of the exploration activities in relation with the Beach Sand Project along the eastern Bay of Bengal, no systematic exploration for uranium had been done before December 1976, when a radiometric survey was implemented by the IAEA. As a result of this survey high radioactivity up to 450 cps was detected in placer Tipam deposits, The background of the terrain made up by Tertiary sediments is 160 - 170 cps. An anomaly was found in Kalipur Chara area which coincides with concentration of heavy minerals derived from Tipam Sandstones. Another anomaly was found within a horizon of Tipam sandstone crossing Hari River. An isolated outcrop in the riverbed showed a count rate up to 4 times background. During the follow up work it was found that this steeply dipping mineralized band stretches (with interruptions) over a distance of at least 3km along a strike. Samples collected from three different spils showed concentration of uranium 50, 60 and 140 ppm. The mineralized bed varies in thickness from a few cm to 2 m. It consists of alternating altered and unaltered sandstone. Bangladesh and Australian experts have separated monazite, zircon, ilmenite, rutile and magnetite from local sands at Cox's Bazar, 96 km southeast of Dacca. Radioactive mineral content is around 3,1% and exploitation may be feasible. Concerning the present status of exploration the technical assistance mission of the IAEA in the field of uranium exploration in Bangladesh is continuing with the objective to evaluate uranium potential in Chittongong and Sylhet district. Concerning areas favourable for uranium first priority should be given to areas of Hari River and Kalipur Chara where radioactive anomalies were detected. In general the area covered by Tipam Sandstone appears to be favourable for uranium mineralization. The potential for new discoveries in Bangladesh appears to be not too bad. Speculative potential could be in the order of 1-10,000 tons uranium

  8. International Uranium Resources Evaluation Project (IUREP) national favourability studies: Panama

    1977-08-01

    About 20 percent of Panama has been covered by airborne radiometric surveys, largely in the Azuero-Petaquilia area. Essentially no ground examinations have been made. About one third of the country remains unmapped. Most of the rest has been examined only in rapid reconnaissance largely by the United Nations and oil companies. Detailed mapping has been confined to the Canal Zone. No uranium deposits or prospects of economic interest are known in Panama. There appears to be no information available on present exploration activities for uranium. Panama has no specific legislation relating to nuclear energy. However, all mineral deposits belong to the state, except for salt and similar materials, and are governed by the mineral resources code. There appears to be only one remote possibility for uranium mineralization in Panama, namely, sandstone-type deposits. Marginal marine and fluvial sediments, such as host sandstone-type deposits elsewhere, are most abundant 1n the lower Cenozoic parts of the Azuero and possibly Bocas del Toro basins and are probably absent or poorly developed in the Darien and Central basin. Rocks with even moderate background uranium concentrations to be leached and deposited in such sediments are confined to the silicic and alkaline Intrusive rocks of the La Yeguada Formation 1n western Panama and possibly the Rio Guayabo stock in the Sierra de Maje of eastern Panama. Only the La Yeguada Formation is extensive enough and near enough to a potential sedimentary ore host to be important. Uranium concentrations have not been measured in this unit but its silicic composition, relatively young age (with respect to other volcanic rocks in Panama) and high ash content suggest that it may have relatively high Teachable uranium content. The best areas for exploration for La Yeguada-derived sandstone-type uranium deposits would be in the Pese formation between Santiago and Chitre in the Azuero basin. Possibly favourable sandstone type exploration ground

    1977-10-01

    Portugal is situated on the western edge of the Iberian Meseta. At present, its reasonably assured reserves are about 7800 t of U (including 1000 t of U at more than 830/lb U 3 O 8 ) and 850 t of U in estimated additional reserves. This potential is divided between vein deposits and deposits located in the peribatholithic schists or enclaved in granite. Two main districts share these reserves - Beira at the centre of the country and Alto Alentejo in the east, approximately at the same latitude as Lisbon. In spite of the considerable prospecting activities authorized by Portugal in the Meseta area, the subject cannot yet be regarded as exhausted. Additional resources may still be located in the horizontal and vertical extensions of the vein mineralizations or schists from the already known deposits or outside the districts containing such deposits. Moreover, certain post-Palaeozoic sedimentary basins exhibit features favourable for the presence of uranium-bearing deposits and therefore deserve to be taken into consideration. However, there are as yet no examples of economic mineralization in such locations in Portugal. All things considered, we considered it reasonable to place Portugal in category No. 3 of the classiffication adopted by BJREP. (author)

    1977-08-01

    Exploration for mineral deposits in Canada resulted in the discovery of large uranium deposits, such as at Great. Bear Lake, Northwest Territories (1930), in the Elliot Lake area, Ontario (1949); Beaverlodge, Wollaston Lake Fold Belt and Carswell Structure in Saskatchewan (1946-1975) and many uranium occurrences in the Canadian Shield, in the Orogenic Belts and in the Platforms. Uranium output in Canada since 1942 until and including 1976 amounted to 112,000 tonnes U. Reasonably Assured uranium resources as of 1976 amounted to 167,000 tonnes U (at a price up to $40/lb. U 3 0 8 ) and 15,000 tonnes U (at a price more than $40 up to $60/lb. U 3 O 8 ). Estimated Additional uranium resources as of 1976 amounted to 392,000 tonnes U (at a price up to $40/lb. U-Og) and 264,000 tonnes U (at a price more than $40 up to $60/lb. U 3 0 8 ). Possible further potential beyond the above mentioned classes is tentatively estimated to be in the 6th category according to NEA/IAEA favourability classification. (author)

  11. International Uranium Resources Evaluation Project (IUREP) national favourability studies: India

    1977-08-01

    Physiographically India has a total area of 3,268,010 km 2 in three distinct regions. 1. The Peninsular shield in the south with an area of 823,310 km 2 . 2. The Himalayan mountain system with an area of 1,797,200 km 2 . 3. The Indo-Gangetic alluvial plain with an area of 647,500 km 2 . The three presently recognised major uranium provinces in India are: 1. The Singhbhum uranium province; 2. The Rajasthan uranium province, 3. The Madhya Pradesh uranium province. The Atomic Minerals Division of the Department of Atomic Energy has carried out a vigorous exploration programme since 1949 but despite their efforts a great deal of ground has still to be explored. At present, structurally controlled deposits account for most of the uranium resources of India. Uranium occurrences and deposits have been outlined in (1) Vein type deposits (the Singhbhum belt), (2) Conglomerate (Karnataka and Udaipur area, Raiasthan), (3) Sandstones (Madhra Pradesh and Swaliks, Himachal Pradesh, (4) Others such as carbonatites, marine phosphates, etc, (Mussorrie - Sahasradhara In Uttar Pradesh and Chatterpur-Saucur in Madhya Pradesh), (5) By-product Uranium in copper tailings and beach sands. India's total resources are listed as 52,538 tonnes uranium (68,300 short tons U 3 O 8 ) with additional resources from monazite of 12700 tonnes uranium. In view of the wide geological favourability, the many types of occurrences already known and the vast areas of unexplored ground it is estimated that the Speculative Potential may be between 150,000 and 250,000 tonnes uranium which is Category 5.

  12. International Uranium Resources Evaluation Project (IUREP) national favourability studies: France

    1977-09-01

    France, with an area of 550,000 km 2 , has been prospecting its territory for uranium for more than 30 years. The proven uranium reserves in all the ore categories defined by the NEA/lAEA are estimated at around 120,000 tU, of which 25,000 tU have already been mined. About 70% of these reserves are associated with granites, while the bulk of the remainder is located in Permian sediments and the last in Paleogene sediments. The prospecting effort has not been distributed equally over French territory. More than half of it - recent orogens and large basins - have been little or very little prospected. On the other hand, the Hercynian massifs and their Upper Paleozoic mantle have been systematically prospected. Nevertheless, even within the latter there is still room for further exploration: extensions of already known mineralizations both laterally and vertically, conventional mineralizations deep down or under a mantle, types of mineralizations not investigated previously (those associated with acid or intermediate vulcanism, peribatholithic shales, alkaline complexes etc.). Of course, in the areas that have not been so well explored, because they appear less favourable, there are still some possibilities, namely, in the areas of recent orogens, mineralizations associated with antemesozoic cores (same types as above) or directly associated with orogenesis (slightly to moderately metamorphic sandstone-phyllitic formations, certain sedimentary formations etc.). As for the large basins, they are capable of containing mineralizations associated with some of their formations (Paleogene of the Basin of Aquitaine etc), but they may also cover workable uranium deposits. It is possible that, in the not to distant future access may be gained to such ores in particular cases. On this basis it does not seem unreasonable to reckon with the discovering of new resources of an order of magnitude between half and the same as those already found. (author)

  13. International Uranium Resources Evaluation Project (IUREP) national favourability studies: Nigaragua

    1977-08-01

    On invitation of the Nicaraguan Government, the U. S. Atomic Energy Commission conducted a reconnaissance for uranium in March, 1953. Operating and abandoned mines, as well as prospects, formations, contacts, dikes and sills enroute to these mines were tested by scintillometer. Reconnaissance included two mineralized areas exposed in windows within the volcanic belt but did not include the schists and granitic intrusions in the north eastern part of the country. No anomalous radioactivity was detected. No uranium occurrences were discovered during the 1953 reconnaissance and no uranium deposits or prospects are indicated on the metallogenetic map of Central America or in the bibliography of Nicaraguan geology. Information is net available on current exploration in Nicaragua. All subsoil mineral resources besides quarry materials belong to the state. In the interest of national defence, uranium, thorium, lithium and their derivatives, along with certain other mineral substances, may be classified as o f temporary strategic interest , and their exploration or exploitation would then be subject to special laws. The Ministry of Economy may establish permanent or temporary national reserves on which mining activities are essentially precluded. Foreign nationals and corporations may acquire mineral concessions although particular regulations may be applicable to such an acquisition. Exploration of any favourable formations has been hindered by volcanic ash cover in western Nicaragua and dense vegetation in the East. Little geologic work has been done on the Paleozoic metamorphic rocks or Todos Santos Formation of the Northern Highlands. These could possibly show some potential for discovery of uranium as might the alaskites near Siuna. The potential resources of Nicaragua are estimated at less than 1,000 tonnes uranium

  14. International Uranium Resources Evaluation Project (IUREP) national favourability studies: Mexico

    1977-07-01

    Reserves of uranium are located in the north eastern part of Mexico, primarily in the states of Tamaulipas and Chihuahua. Most of the remainder of Mexico's reserves are near the Tamaulipas-Neuvo Leon state border in the Tertiary Frio Formation, where they apparently occur in the types of uranium deposits found in Texas, U.S.A. There are two deposits, La Coma and Buenavista, but nothing has been published on dimensions of the ore bodies. Forty-five miles northeast of Hermosillo, in Sonora state is the Los Amoles district where uranium is found associated with gold and other metals in low-grade deposits on the margins of a Cretaceous batholith. Another occurrence is reported in the mining district of Placer de Guadelupe and Puerto del Aire, about 40-50 km northeast of Chihuahua City, in the state of Chihuahua. Reserves of U 3 O 8 which were published in January 1977 by Nuclear Exchange Corporation of Menlo Park, California, are listed. The government of Mexico has not estimated potential resources. It should be noted that much of Mexico appears favourable for uranium, and only 10 percent has been explored. According to NUEXCO (1977), efforts to find uranium are being increased in an attempt to supply Mexico's nuclear reactor requirements through 1990. Activity is reported to be centered in Tamaulipas and Chihuahua states and to a lesser extent in Nueva Leon, Sonora, Coahuila, and Baja California. Major effort will continue to be placed in Chihuahua state to supply the Penna Bianca mill. Correspondence between favorable geological settings for uranium and the geologic regions of Mexico is reported. Mexico is a country with considerable areas that appear promising for discovery of sandstone, vein, and tuff-related deposits. On the other hand, its potential for Precambrian conglomerate and unconformity-related deposits is limited. Considering these geologic factors, as well as the relatively limited amount of exploration done to date, a guesstimate of speculative

  15. International Uranium Resources Evaluation Project (IUREP) national favourability studies: Spain

    1977-10-01

    Spain, with an area of 504 748 km''2, occupies a large part of the Iberian Peninsula. At present the country appears to have about 6300 t of reasonably assured uranium reserves and 8500 t of additional estimated reserves (all at less than $30/lb of U 3 O 8 ). Spain has devoted some $33 million to prospecting for uranium since the beginning of such work. Most of the reasonably assured reserves are located in ores impregnating Cambrian schists intersected by Hercynian granites (of so-called 'Iberian type'); a small amount, however, is found in veins in Hercynian granites of the Spanish Meseta. The additional estimated reserves are situated in the peripheral post-Hercynian continental basins of the Meseta. Apart from these classical ores, sub-ores have been identified in Silurian quartzites with low concentrations of uranium associated with refractory minerals, totalling more than 200,000 t of U (at concentrations of a few hundred ppm); there are likewise uranium-bearing Oligocene lignites in the Ebro Basin with some 140,000 t of U. These facts, and also the very wide distribution of uranium in space and time (from the Cambrian to the Miocene!) and the country's favourable geological characteristics, suggest that Spain ought in fact to have large reserves of uranium, a conclusion unfortunately belied by the paucity of the economic reserves identified so far. Two things must be borne in mind, however; firstly, Spain's financial outlay for uranium prospecting up till now represents only a quarter of what has been invested in France, for example, and, secondly, the nature of the mineralised bodies in Spain makes exploration difficult. In conclusion it seems that prospecting both of the Iberian-type deposits in the Meseta region and of the deposits associated with detrital sediments in the peripheral continental basins - especially blind mineralized bodies - should hold out excellent prospects for Spain. Consequently we propose that Spain should be placed at least in

    1977-11-01

    Very little information is available to IAEA on the geology and uranium potential of Syria. In 1975 a contract was awarded to Huntings Geology and Geophysics Ltd by the Ministry of Petroleum and Mineral Resources to carry out a study of the country's mineral resources with particular reference to phosphate uranium, chrome and industrial materials. The results of this survey are not known. Apart from the assumption of some possibility of uranium recovery as a by-product from phosphate production it is assumed that the Speculative Potential is likely to be less than 1000 tonnes uranium.

  18. International Uranium Resources Evaluation Project (IUREP) national favourability studies: Guatemala

    1977-08-01

    Before 1959 a private individual (Mr. Rene Abularach) is reported to have made an airborne radiometric survey of the Sierra de las Minas and Sierra Madre Ranges. Although many anomalies were detected by this survey, none were verified in the ground survey followup, despite apparently adequate flight control. In 1968 a United Nations Special Fund Mineral Survey Project completed over 1,000 km of carborne radiometric survey with geiger counter readings at 500 m intervals. No anomalies were detected, but background radioactivity for several formations and geologic environments was established. In 1969 the Guatemalan government solicited the IAEA for technical assistance In conducting a preliminary uranium favorability study designed to formulate recommendations for a national radioactive ore prospecting program. A carborne radiometric survey was made of environments theoretically favorable for uranium deposition, with spot geological and radiometric examinations being .conducted in the more favorable areas. All Important mining regions of Guatemala except the leterites and the ultrabasics were visited. No evidence of a uranium province was observed 1n these field investigations and the recommendation was made that the government not embark on a more detailed national prospecting program at that time. At the time of completion of the IAEA-Guatemalan government (GOG) reconnaissance program in 1971, no uranium reserves or resources were known. More recent information on uranium occurrences and resources 1n Guatemala does not appear to be available. Information on more recent uranium reconnaissance than that undertaken during 1971 IAEA-GOG study is lacking. However, in more recent years the country's mineral potential has been generally evaluated with the aid of the UN and ICAITI (Central American Research Institute for Industry). Except for quarry materials, the state owns all minerals. The state has priority on purchase of any mineral production needed for the country

  20. Innovation in learning and development in multilingual and multicultural contexts: Principles learned from a higher educational study programme in Luxembourg

    Ziegler, Gudrun

    2011-12-01

    Multilingualism in education is a conceptual as well as a pedagogical challenge of the 21st century. Luxembourg, with its three statutory official languages (Luxembourgish, French and German), is an especially complex setting. The gap between traditional principles of language education on the one hand and the challenging impacts of today's multilingualisms on the other led the University of Luxembourg (founded in 2003) to set up a developmentally-driven Master's programme in 2007, entitled "Learning and Development in Multilingual and Multicultural Contexts". After a presentation of the general multilingual settings in Luxembourg, this paper discusses the constellation of the multilingual University's staff and students and provides an analysis of the concept of the course by outlining its innovative approach, its principles and lessons learned with regard to running a trilingual higher education programme.

  1. Physical activity, sedentary behavior time and lipid levels in the Observation of Cardiovascular Risk Factors in Luxembourg study.

    Crichton, Georgina E; Alkerwi, Ala'a

    2015-08-11

    Recently attention has been drawn to the health impacts of time spent engaging in sedentary behaviors. While many studies have investigated general physical activity (PA) in relation to blood lipid levels, the current study aimed to examine the intensity of activity, including sedentary behavior time, and time spent engaging in moderate and intense PA, with concentrations of HDL and LDL-cholesterol, total cholesterol, and triglycerides. Participants comprised 1331 individuals, aged 18 to 70 years, from the Observation of Cardiovascular Risk Factors in Luxembourg (ORISCAV-LUX) study, who underwent objective cardiovascular health assessments and completed the International Physical Activity Questionnaire (IPAQ). Time spent engaging in sedentary behaviors (screen time on a workday and a day off, and total sitting time on a work day), and moderate and intense PA, were related to levels of HDL and LDL-cholesterol, total cholesterol, and triglycerides. Analyses were conducted in the whole sample, and then with stratification according to BMI (normal weight versus overweight/obese). Both lower screen time during days off and higher intense PA time were significantly associated with higher HDL-cholesterol after full adjustment for socio-demographic factors, dietary factors and smoking (both p sedentary behavior time variables were observed (all p sedentary behavior time variable and lipid levels in those overweight or obese. Spending less time in sedentary behaviors, and engaging in medium levels of intense physical activity may be associated with a more favorable blood lipid profile, particularly with regard to levels of HDL and triglycerides.

  2. Psychosocial risk and protective factors of secondary school dropout in Luxembourg: the protocol of an exploratory case-control study.

    In Luxembourg, the extensive phenomenon of school dropout is a prime policy concern in the light of individual, social and economic consequences. Although the authorities report an overall decrease of the national dropout rate, the proportion of early school leavers who remain without any specific occupation is still alarming. Therefore, this study intends a shift of focus from system-inherent to individual factors, including mental health and family correlates, to provide a more comprehensive analysis of the dropout phenomenon. The objectives of this study are to investigate the type and prevalence of psychiatric disorders among school dropouts and to compare the findings with those by a matched control group of regularly enrolled students. Furthermore, family variables and socioeconomic status will be analysed, as they are factors likely to interfere with both educational attainment and mental health. A trained psychologist will use structured interviews and self-report forms to investigate for mental health issues, information on schooling, socioeconomic situation and family life. Controls will be matched for gender, age, school type and educational grade. As school dropouts face a serious risk of long term professional and social marginalization, there is an evident need for action. Identifying psychosocial risk and protective factors of school dropout will deliver solid insight on how to conceive public health strategies for young people who may need a more customized support to carry out their academic potential.

  3. From the Harvard Medical Practice Study to the Luxembourg Declaration. Changes in the approach to patient safety. Closing remarks

    2005-12-01

    Full Text Available Since the Harvard Medical Practice Study was published in 1991 the growing mass of international literature has demonstrated that medical adverse events can cause iatrogenic illnesses, prolonged hospitalisations and increased costs. In 1999-2001, reports made by the Institute of Medicine (IOM in the USA, the Department of Health (DoH in the UK and the Australian Patient Safety Foundation (APSF stressed the necessity for creating a safer environment and a reporting culture throughout healthcare systems. They also emphasized the need for researchers to investigate means of turning policies into practice. Since their publication a lot of effort has gone into collecting data on adverse events and near misses. As a result, in 2001, the AHRQ published a Health Technology Assessment report on best practices for patient safety. While in Australia national meetings have been dedicated to address important issues across the whole spectrum of healthcare. In the UK the Audit Commission has published a report that is also focused on medication safety: “A spoonful of sugar”. In 2004 the World Health Organisation promoted a Patient Safety Alliance; while in April 2005the Standing Committee of European Doctors organised a Conference in Luxembourg called “Patient safety - Making it happen!”. The issue of patient safety is therefore seen as a priority by EU institutional bodies and by many European health stakeholders.

  4. Social and economic inequalities in fatal opioid and cocaine related overdoses in Luxembourg: a case-control study.

    Origer, Alain; Le Bihan, Etienne; Baumann, Michèle

    2014-09-01

    To investigate social and economic inequalities in fatal overdose cases related to opioid and cocaine use, recorded in Luxembourg between 1994 and 2011. Cross-examination of national data from law enforcement and drug use surveillance sources and of forensic evidence in a nested case-control study design. Overdose cases were individually matched with four controls, when available, according to sex, year of birth, drug administration route and duration of drug use. 272 cases vs 1056 controls were analysed. Conditional logistic regression analysis was performed to assess the respective impact of a series of socioeconomic variables. Being professionally active [OR=0.66 (95% CI 0.45-0.99)], reporting salary as main legal income source [OR=0.42 (95% CI 0.26-0.67)] and education attainment higher than primary school [OR=0.50 (95% CI 0.34-0.73)] revealed to be protective factors, whereas the professional status of the father or legal guardian of victims was not significantly associated to fatal overdoses. Socioeconomic inequalities in drug users impact on the occurrence of fatal overdoses. Compared to their peers, users of illicit drugs with lower socioeconomic profiles show increased odds of dying from overdose. However, actual and self-referred socioeconomic characteristics of drug users, such as educational attainment and employment, may have a greater predictive value of overdose mortality than the parental socioeconomic status. Education, vocational training and socio-professional reintegration should be part of drug-related mortality prevention policies. Copyright © 2014 Elsevier B.V. All rights reserved.

  5. Prevalence and Correlates of Vitamin D Deficiency and Insufficiency in Luxembourg Adults: Evidence from the Observation of Cardiovascular Risk Factors (ORISCAV-LUX Study

    Ala'a Alkerwi

    2015-08-01

    Full Text Available Evidence on vitamin D status and related risk factors in Luxembourg adults is lacking. This study aimed to determine the prevalence of vitamin D deficiency and insufficiency and related risk factors among healthy adults in Luxembourg. Based on clinicians’ observations, it was hypothesized that vitamin D deficiency and insufficiency might be common in our population, constituting a significant public health concern. A nationally representative random sample of 1432 adults was enrolled in the ORISCAV-LUX study, 2007–2008. The participants were divided into four categories according to their serum concentrations of 25-hydroxyvitamin D [25(OHD]. Descriptive, univariate and multivariate statistical analyses used weighted methods to account for the stratified sampling scheme. Only 17.1% of the population had a “desirable” serum 25(OHD level ≥75 nmol/L, whereas 27.1% had “inadequate” [serum 25(OHD level 50–74 nmol/L], 40.4% had “insufficient” [serum 25(OHD level 25–49 nmol/L], and 15.5% had “deficient” [serum 25(OHD level <25 nmol/L]. The prevalence of vitamin D deficiency was greater among current smokers, obese subjects, those having reduced HDL-cholesterol level and fair/poor self-perception of health, compared to their counterparts. The prevalence of vitamin D insufficiency was additionally higher among nondrinkers of alcohol, Portuguese and subjects from non-European countries. The final multivariate logistic regression analyses revealed that smoking status and obesity were independent correlates of vitamin D deficiency and insufficiency, respectively. Inadequate vitamin D status is highly prevalent among adults in Luxembourg and is associated with specific lifestyle factors. Along with the effect of vitamin D deficiency and insufficiency on the risk of several diseases, cancer and mortality, our findings have practical implications for public health dietary recommendations, and of particular importance for healthcare

  6. Public and private energy RTD expenditures in Belgium, Luxembourg and the Netherlands. A pilot study on behalf of SenterNovem based on an IEA format

    Lako, P.; Ros, M.E.

    2007-07-01

    This study aims to present a broad view of energy RTD expenditures of Belgium, Luxembourg, and the Netherlands, in the public domain and by private enterprises. Data is provided as much as possible by disaggregating into a format of the IEA (IEA code). IEA data serve as the starting point for data collection. The main task is to fill in the gaps in the database, viz.: Completing the IEA database for Belgium with regard to public energy RTD; Starting with a database of public energy RTD for Luxembourg; Collecting, retrieving, and analysing private energy RTD data for the Netherlands. The latter data, based on a 'bottom-up' approach, are compared to recent data of SenterNovem based on an R and D subsidy scheme in the Netherlands. The private energy RTD expenditures from both sources (the bottom-up approach in this study and the data of SenterNovem) are combined to one database of private energy RTD that may be used for, e.g., the IEA

  7. Daily chocolate consumption is inversely associated with insulin resistance and liver enzymes in the Observation of Cardiovascular Risk Factors in Luxembourg study.

    2016-05-01

    This study examined the association of chocolate consumption with insulin resistance and serum liver enzymes in a national sample of adults in Luxembourg. A random sample of 1153 individuals, aged 18-69 years, was recruited to participate in the cross-sectional Observation of Cardiovascular Risk Factors in Luxembourg study. Chocolate consumption (g/d) was obtained from a semi-quantitative FFQ. Blood glucose and insulin levels were used for the homoeostasis model assessment of insulin resistance (HOMA-IR). Hepatic biomarkers such as serum γ-glutamyl-transpeptidase (γ-GT), serum aspartate transaminase and serum alanine transaminase (ALT) (mg/l) were assessed using standard laboratory assays. Chocolate consumers (81·8 %) were more likely to be younger, physically active, affluent people with higher education levels and fewer chronic co-morbidities. After excluding subjects taking antidiabetic medications, higher chocolate consumption was associated with lower HOMA-IR (β=-0·16, P=0·004), serum insulin levels (β=-0·16, P=0·003) and γ-GT (β=-0·12, P=0·009) and ALT (β=-0·09, P=0·004), after adjustment for age, sex, education, lifestyle and dietary confounding factors, including intakes of fruits and vegetables, alcohol, polyphenol-rich coffee and tea. This study reports an independent inverse relationship between daily chocolate consumption and levels of insulin, HOMA-IR and liver enzymes in adults, suggesting that chocolate consumption may improve liver enzymes and protect against insulin resistance, a well-established risk factor for cardiometabolic disorders. Further observational prospective research and well-designed randomised-controlled studies are needed to confirm this cross-sectional relationship and to comprehend the role and mechanisms that different types of chocolate may play in insulin resistance and cardiometabolic disorders.

  9. Socioeconomic Inequalities in Smoking and Smoking Cessation Due to a Smoking Ban: General Population-Based Cross-Sectional Study in Luxembourg

    Tchicaya, Anastase; Lorentz, Nathalie; Demarest, Stefaan

    2016-01-01

    This study aimed to measure changes in socioeconomic inequalities in smoking and smoking cessation due to the 2006 smoking ban in Luxembourg. Data were derived from the PSELL3/EU-SILC (Panel Socio-Economique Liewen Zu Letzebuerg/European Union—Statistic on Income and Living Conditions) survey, which was a representative survey of the general population aged ≥16 years conducted in Luxembourg in 2005, 2007, and 2008. Smoking prevalence and smoking cessation due to the 2006 smoking ban were used as the main smoking outcomes. Two inequality measures were calculated to assess the magnitude and temporal trends of socioeconomic inequalities in smoking: the prevalence ratio and the disparity index. Smoking cessation due to the smoking ban was considered as a positive outcome. Three multiple logistic regression models were used to assess social inequalities in smoking cessation due to the 2006 smoking ban. Education level, income, and employment status served as proxies for socioeconomic status. The prevalence of smoking decreased by 22.5% between 2005 and 2008 (from 23.1% in 2005 to 17.9% in 2008), but socioeconomic inequalities in smoking persisted. Smoking prevalence decreased by 24.2% and 20.2% in men and women, respectively; this difference was not statistically significant. Smoking cessation in daily smokers due to the 2006 smoking ban was associated with education level, employment status, and income, with higher percentages of quitters among those with a lower socioeconomic status. The decrease in smoking prevalence after the 2006 law was also associated with a reduction in socioeconomic inequalities, including differences in education level, income, and employment status. Although the smoking ban contributed to a reduction of such inequalities, they still persist, indicating the need for a more targeted approach of smoke-free policies directed toward lower socioeconomic groups.

  10. Hydrodynamic patterns favouring sea urchin recruitment in coastal areas: A Mediterranean study case.

    Farina, S; Quattrocchi, G; Guala, I; Cucco, A

    2018-05-11

    In invertebrate fisheries, sea urchin harvesting continues to grow with dramatic consequences for benthic ecosystems. The identification of areas with a marked natural recruitment and the mechanisms regulating it is crucial for the conservation of benthic communities and for planning the sustainable harvesting. This study evaluates the spatial distribution and density of recruits of the edible sea urchin Paracentrotus lividus along the Sinis + Peninsula (Sardinia) and explores its significant relationships with the local oceanographic features. Our results reveal that recruitment is favoured in areas with slow currents and high levels of confinement and trapping of the water masses. Analysis of the residual circulation indicates that the presence of local standing circulation structures promotes the sea urchin recruitment process. Our findings emphasize the importance of managing local sea urchin harvesting as a system of populations with their demographic influence mainly dependent on the most important ecological driver that is the recruitment.

    Full Text Available Abstract Background Cognitive impairment and Alzheimer’s disease (AD are increasingly considered a major public health problem. The MemoVie cohort study aims to investigate the living conditions or risk factors under which the normal cognitive capacities of the senior population in Luxembourg (≥ 65 year-old evolve (1 to mild cognitive impairment (MCI – transitory non-clinical stage – and (2 to AD. Identifying MCI and AD predictors undeniably constitutes a challenge in public health in that it would allow interventions which could protect or delay the occurrence of cognitive disorders in elderly people. In addition, the MemoVie study sets out to generate hitherto unavailable data, and a comprehensive view of the elderly population in the country. Methods/design The study has been designed with a view to highlighting the prevalence in Luxembourg of MCI and AD in the first step of the survey, conducted among participants selected from a random sample of the general population. A prospective cohort is consequently set up in the second step, and appropriate follow-up of the non-demented participants allows improving the knowledge of the preclinical stage of MCI. Case-control designs are used for cross-sectional or retrospective comparisons between outcomes and biological or clinical factors. To ensure maximal reliability of the information collected, we decided to opt for structured face to face interviews. Besides health status, medical and family history, demographic and socio-cultural information are explored, as well as education, habitat network, social behavior, leisure and physical activities. As multilingualism is expected to challenge the cognitive alterations associated with pathological ageing, it is additionally investigated. Data relative to motor function, including balance, walk, limits of stability, history of falls and accidents are further detailed. Finally, biological examinations, including ApoE genetic polymorphism are

  13. Human Campylobacteriosis in Luxembourg, 2010-2013: A Case-Control Study Combined with Multilocus Sequence Typing for Source Attribution and Risk Factor Analysis.

    Campylobacteriosis has increased markedly in Luxembourg during recent years. We sought to determine which Campylobacter genotypes infect humans, where they may originate from, and how they may infect humans. Multilocus sequence typing was performed on 1153 Campylobacter jejuni and 136 C. coli human strains to be attributed to three putative animal reservoirs (poultry, ruminants, pigs) and to environmental water using the asymmetric island model. A nationwide case-control study (2010-2013) for domestic campylobacteriosis was also conducted, including 367 C. jejuni and 48 C. coli cases, and 624 controls. Risk factors were investigated by Campylobacter species, and for strains attributed to different sources using a combined case-control and source attribution analysis. 282 sequence types (STs) were identified: ST-21, ST-48, ST-572, ST-50 and ST-257 were prevailing. Most cases were attributed to poultry (61.2%) and ruminants (33.3%). Consuming chicken outside the home was the dominant risk factor for both Campylobacter species. Newly identified risk factors included contact with garden soil for either species, and consuming beef specifically for C. coli. Poultry-associated campylobacteriosis was linked to poultry consumption in wintertime, and ruminant-associated campylobacteriosis to tap-water provider type. Besides confirming chicken as campylobacteriosis primary source, additional evidence was found for other reservoirs and transmission routes.

  14. Tea, but not coffee consumption, is associated with components of arterial pressure. The Observation of Cardiovascular Risk Factors study in Luxembourg.

    Alkerwi, Ala'a; Sauvageot, Nicolas; Crichton, Georgina E; Elias, Merrill F

    2015-07-01

    There is uncertainty regarding the impact of tea and coffee consumption on arterial blood pressure. The present study aimed to examine the association between blood pressure (BP) components, namely, systolic BP (SBP), diastolic BP, mean arterial pressure, and pulse pressure (PP), and tea or coffee consumption, taking into account simultaneous consumption. The study population was derived from a national cross-sectional stratified sample of 1352 individuals aged 18 to 69 years, recruited between November 2007 and January 2009 to participate in the Observation of Cardiovascular Risk Factors in Luxembourg study. We hypothesized that greater tea consumption would be independently associated with lower BP. Tea and coffee consumptions in deciliters per day were obtained from a semiquantitative food frequency questionnaire. Participants were classified into 3 groups: nonconsumers, ≤3-dL/d consumers, and >3-dL/d consumers of each beverage separately. After exclusion of subjects taking antihypertensive medications, several general linear models were performed to investigate the independent relationship between tea/coffee consumption and BP components. Tea consumers (36.3%) were more likely to be younger women, nonsmokers, with better cardiometabolic profiles, and less frequent chronic pathologies, whereas the reverse was true for coffee consumers (88%). Greater tea consumption was associated with lower SBP and PP values, after adjustment for age, sex, education, lifestyle, and dietary confounding factors, including coffee drinking. No association between BP components and coffee consumption was observed. Daily consumption of 1 dL of tea was associated with a significant reduction of SBP by 0.6 mm Hg and PP by 0.5 mm Hg. Given the widespread consumption of tea and coffee throughout the world, together with the major cardiovascular disease risk, our findings have important implications for human health.

    1977-12-01

    Mongolia, a country of 1,525,000 square kilometers, and a population of almost the same number of people is land locked between China and USSR. Historically it's closest ties have been with China, but it is now more closely associated with USSR. Geologically it's complex - most exposed formations are younger than PreCambrian although old exist. Potential for uranium is considered fairly good because the fairly complex geology appears to be favourable both for continental sandstone type deposits and calcretes (less than 50%) and vein type, and other deposits (more than 50$). Considerable effort should be made to obtain additional information related to Mongolian geology. (author)

    China with an area close to 10,000,000 sq km and a fifth of the world's population, has a history of mining and, in fact is quite self sufficient in most of it's needs for the more basic mineral products.However, there is a dearth of knowledge of its resources of uranium. One can however, make the assumption that geologically, there are probably several areas that contain the combination of favourable host rocks and source. The speculative potential of China is estimated to be in Category 5, 100,000 to 500,000 tonnes U. (author)

    New Caledonia is an island and with dependencies totals just over 1900 square kilometers in area and contains an estimated 128,000 people. Its principal products are nickel and chrome, but agricultural products assume considerable importance in addition. Geologically New Caledonia is quite complex, and on the basis of the complexity of geology and the relative intensity of the mineralization of the island as well as apparent favourable host rocks a category 2 - 1,000 - 10,000 tonnes U - (nearer to 1,000 than 10,000) is assigned.

    2009-01-01

    This report is a synthesis of the possibilities of CO 2 storage in the Spanish subsurface. Compilation and analysis of geological information has been carried out, looking at surface and subsurface, in order to make a pre-selection of potential favourable units for CO 2 storage, taking in account that each of this storages needs a confining formation to seal the storage. Before the storage selection, a general description of the great geological units of the Iberian Peninsula is done. Afterwards, borehole logging from petroleum exploration is analysed in these units, formations and areas of interest. The aim is to finally obtain a description of selected units and their possibilities of CO 2 storage. (Author) 17 refs

  20. International Uranium Resources Evaluation Project (IUREP) national favourability studies: Saudi Arabia

    1977-09-01

    Saudi Arabia occupies most of the Arabian Peninsula and has an area of 872,722 sq miles, or 2,260,350 sq km. The ancient Arabian Shield of igneous and metamorphic rocks comprises most of the western third of the country. The shield contains many extinct volcanoes surrounded by lava beds. Sloping eastwards are the newer sedimentary areas in which rich oil fields are found. In Saudi Arabia oil is paramount and less effort has been put into searching for mineral deposits than in other countries of similar size and geology. Pour aerial radiometric surveys have been undertaken and some of the anomalies discovered in the earlier ones were ground checked by an IAEA expert in 1963-64. Two anomalies warranted more detailed work, these were the Jabal Said anomaly in the Central Shield area and the Al Ghrayyat in Wadi Sawawin about 70 miles from the Jordan border. The Jabal Said anomaly consists of a zone of altered rocks consisting largely of pegmatite and pegmatite granite= Allanite, pyrochlore, cyrtolite, xenotime and monazite are the ore minerals,, The deposit was estimated to have 2.2 million tons of ore grading 0.2 - 0.3 percent Nb 2 O 5 and 0.03 - 0,05% U 3 O 8 . The other occurrence at Al Ghrayyat is similar but with much lower grade uranium content. In view of the huge size of Saudi Arabia, the existence of many geologically favourable rock types and the poor coverage by sophisticated uranium exploration techniques, the Speculative Potential is placed between 10,000 and 50,000 Tonnes uranium.

    prospective rocks. The Permian or Triassic granite and Triassic acidic volcanics are possible source rocks for uranium in the Mesozoic sediments, although the uranium levels are unknown. Granitic rocks of similar age, exposed in the western part of Irian Jaya (Rirdshead) are accompanied by radiometric anomalies and are known to contain monazite, allanite, xenotime, zircon, and thorite. Miocene and younger intrusions - principally diorite, tonalite, and granodiorite - in the central range, contain up to 4 ppm U and 16 ppm Th, while Tertiary intrusives in New Britain and the Solomon Islands contain less than 2.5 ppm U and 7 ppm Th. Quaternary volcanics in New Britain and on islands off the North New Guinea coast have low levels of U and Th similar to those of the Tertiary intrusives in the area. Some of the tertiary limestone deposits in Papua New Guinea could be potential host rocks to uranium. The most favourable rock unit is Miocene basinal limestone on the platform; it consists of argillaceous micrite and biomicrite, and calcareous mudstone, and is a source and (locally) a reservoir rock of petroleum. Apart, from the inherent difficulties of exploration of a remote region an added problem is the difficulty of airborne surveying in areas of rugged topography and terrain covered by dense forest. In lowland areas there are the additional problems of permanent water cover, leaching of the surface rocks, and heavy soil cover

  2. [Sports in Luxembourg. The role of heart healthy sports].

    Delagardelle, C

    2015-01-01

    30 years of organized ambulatory heart sport in Luxembourg Promoter of health sports. For more than 30 years both mortality and morbidity due to coronary artery disease (CAD) are significantly decreasing (> 70%) in the western world. This achievement is due to multiple interventions in the direct treatment of CAD and, especially, in fighting its risk factors: smoking, high blood pressure, hypercholesterolemia and physical inactivity. In 1984 the first ambulatory heart sport group (phase 3 of cardiac reeducation) was founded in Luxembourg City, followed in 1991 by a section in Esch/Alzette and in 2002 by a 3ème section in Ettelbrück. These phase 3 cardiac sport groups (= chronic phase) are organized by some committed patients working on a voluntary basis and performing a professional job. Paradoxically these phase 3 groups preceded the phases 1 and 2 (= "in hospital" and subacute) of cardiac rehabilitation. However, in a parallel way ambulatory phase 2 physical activity (PA) was started in the main hospitals in Luxembourg City (Centrum), Esch/Alzette (South) and Ettelbrück ( North). In 2002 a cornerstone study by Myers et al proved that physical fitness is the most determinant of survival both for healthy people and for cardiac patients: The better the fitness, quantified in METs, the better the prognosis and this fact is the basis for the application of sports therapy in cardiac and most other patients. An important epidemiological study published in 2012 by Lee et al in Lancet analyzed the effects of physical inactivity (PI) all over the world: 4 important diseases were studied: CAD, breast cancer, colon cancer and type 2 diabetes. The effects of PI are most pronounced in colon cancer followed by diabetes 2, breast cancer and then CAD. As a mean about 9% of all deaths -5.9 million in 57 million deaths/year worldwide- are caused by PI and for Luxembourg 12.9%. This cornerstone study can serve as rationale for physical therapy (PT) intervention in oncology

  4. International Uranium Resources Evaluation Project (IUREP) national favourability studies: El Salvador

    1977-08-01

    No information is available on past uranium exploration in El Salvador. The foetallogenic map of Central America (ICAITI, 1970) shows no uranium occurrences, and no descriptions of occurrences are available for this study. Information on current uranium exploration in El Salvador is not available. The 1922 mining code, as amended, covers all minerals, with special rules applicable to phosphates, petroleum and other hydrocarbons. The state owns all minerals, including phosphates, except for salt and other common materials. Mineral and surface rights are distinct. Both citizens and aliens may acquire mineral rights. There is a possibility of uranium potential in the clastic sediments containing interbedded volcanics, particularly where the latter are tuffaceous. These rocks occur chiefly in the north western part of the country and are of limited areal extent. The possibility of uranium occurrences associated with acid volcanics cannot be discounted, but it is difficult to evaluate rocks of this type for uranium with the present state of knowledge. Accordingly, potential resources are estimated at between 0 and 1,000 tonnes uranium

  5. International Uranium Resources Evaluation Project (IUREP) national favourability studies: Costa Rica

    1977-08-01

    Most parts of Costa Rica, except for the Quaternary volcanic belt, have neither been studied or mapped in detail. Concerning past exploration limited uranium exploration took place in the late 1960's but details are lacking. No additional information is available. A bibliography of Costa Rican geology (Dengo, 19t>2a) and the metallogenic map of Central America (1CAITI, 1970) do not report any uranium occurrences. Data on current exploration activities for uranium are lacking. Mining is essentially regulated by a 1953 code and a 1964 supplement, but the production and use of radioactive materials are controlled by the Costa Rican Atomic Energy Commission. New raining and petroleum laws reportedly are being considered. Mining rights are available with few restrictions to foreign nationals and corporations. Costa Rica contains no rocks older than Cretaceous. The Mesozoic continental clastic sequences of Honduras and northern Nicaragua do not extend this far south. The massive intrusions of acidic granites and syenites in the Talamanca ranges are probably older than the oldest formations now seen adjacent to them and could not have contributed to their mineralization except through weathering. There may be a faint possibility for uranium deposition in lodes and fracture zones within the granitic rocks, but no such deposits have been reported. Insofar as the sediments are concerned, only the shallow water faces of the marine sediments of the Caribbean coastal region offer the remotest possibilities. The uranium potential of Costa Rica is estimated, at less than 1,000 tonnes

  6. Grand Duchy of Luxembourg. Country profile.

    Inserra, P

    1985-09-01

    This article provides a profile of Luxembourg, a country known for its high standard of living and social stability. The total fertility rate in Luxembourg in 1983 was 1.4. 26% of the population are immigrants. The total population of teh country stood at 364,602 in 1981 and is expected to decline to 349,000 by the year 2000 if present trends continue. Immigration is actively promoted to provide manual labor; about 30% of immigrants are from Portugal. The 1981 census counted 128,456 households in the country, with an average household size of 2.83 people. 24% of men over 18 years and 23% of women over 15 years have never married. Although only 19% of men over age 65 years are widowers, 55% of women in this age group are widows. About 50,000 Luxembourgers are over 65 years of age. In 1983, the full time work force was 158,500 and the unemployment rate was 1.6%. Women comprise about 40% of the labor force. The inflation rate has declined sharply, from 8.6% in 1983 to 5.7% in 1984. A large portion of the average household budget is allocate toward further education, leisure, and culture. About 70% of the population are homeowners. The atmosphere of austerity present elsewhere in Europe has not affected Luxembourg; leaders are optimistic about the country's economic future.

    2006-01-01

    Brain disorders (psychiatric, neurological and neurosurgical diseases) are leading causes of disease and disability. According to WHO data they cause 35% of the burden of all diseases in Europe. The present study aims to estimate the cost of defined brain disorders and adds all selected disorders to arrive at the total cost for Luxembourg. A model combining published economic and epidemiological data retrieved from the OECD (Organization for Economic Co-operation and Development) and Eurostat databases on brain disorders in Europe (EU member countries, Iceland, Norway and Switzerland) was used. We transformed and converted data for a defined period into the same currency (Euro 2004) and adjusted country specific economic data for purchasing power and relative size of economy and imputed data where no local data were available. There are an estimated 123000 people in Luxembourg currently living with a brain disorder. The total annual cost of brain disorders is estimated at Euro 500 million in 2004 or an average of Euro 1100 per inhabitant. Mental disorders constitute 62% of the total cost (excluding dementia), followed by neurological diseases (excluding dementia) 22%, neurosurgical diseases excluding herniated discs 2.2%. Direct medical expenditures (outpatient care, hospitalization, drugs) have a share of 32%, direct non-medical costs (social services, informal care, adaptation, transportation) 18% and indirect costs (sick leave, early retirement and premature death) 51%.

    In Luxembourg, electricity from renewable sources is mainly promoted through a feed-in tariff as well as through subsidies. Private individuals operating small solar installations are entitled to tax benefits. The production of heat from renewable energy sources is promoted through four different subsidy schemes. Finally, the only support scheme for renewable energy sources used in transport is a quota system. Several policies aim at promoting the development, installation and usage of RES-installations, such as a training programme for RES-installers; a general research, development and demonstration (RD and D) programme and support schemes for RES-H infrastructures (source: RES-Legal Europe)

  10. Euthanasia in Belgium, the Netherlands and Luxembourg.

    2013-11-01

    Each of the Benelux countries (Belgium, Luxembourg, Netherlands) has enacted legislation that partially decriminalises euthanasia, defined as an act that intentionally terminates someone's life at their request. In the Netherlands and Luxembourg, but not in Belgium, the legislation partially decriminalised assisted suicide at the same time. In all three countries, euthanasia can only be performed by a doctor, in response to the patient's voluntary and well-considered request, and for patients who have an incurable disease that causes unbearable suffering, without any prospect of relief. In the Netherlands, minors can request euthanasia as of the age of 12 years. In 2011, reported euthanasia accounted for about 1% of deaths in Belgium and 3% in the Netherlands. In 75% of cases, cancer was the disease leading to a request for euthanasia. In the Netherlands, the number of cases of euthanasia reported by doctors in surveys matches the number that is officially declared. In Belgium, it is thought that there are as many unreported as reported cases of euthanasia. Since the enactment of euthanasia legislation, fewer deaths involve the intentional administration of lethal drugs without an explicit request from the patient.

  13. Energy policies of IEA countries: Luxembourg -- 2008 Review

    NONE

    2009-03-20

    Luxembourg has reformed its energy policies across all sectors since the last IEA in-depth review in 2004. The country has fully liberalised its electricity and natural gas markets, and is actively participating in the development of the evolving Central West European regional electricity system. Luxembourg has also prepared a broad action plan on energy efficiency, improved the support system for renewable energy sources and revised taxes to mitigate climate change. The country's energy policy in the coming decade will be shaped by the EU 2020 targets that call for substantial reductions in greenhouse gas emissions, and strong increases in renewable energy and energy efficiency. These targets will be hard to meet, given that roughly half of energy-related CO2 emissions come from transport fuel use by foreign truckers and motorists, and that Luxembourg's potential for producing much more renewable energy is limited. Luxembourg is heavily dependent on oil. Although oil sources are well diversified by country of origin, more than 85% of oil stocks are held in neighbouring countries and often based on short-term leasing contracts. This leaves the country vulnerable to potential oil supply disruptions. Luxembourg should swiftly implement a plan to improve the security of oil supply. This review analyses the energy challenges facing Luxembourg and provides critiques and recommendations for further policy improvements. It is intended to help guide the country towards achieving its sustainability targets.

  14. A hepatitis A, B, C and HIV prevalence and risk factor study in ever injecting and non-injecting drug users in Luxembourg associated with HAV and HBV immunisations.

    Removille, Nathalie; Origer, Alain; Couffignal, Sophie; Vaillant, Michel; Schmit, Jean-Claude; Lair, Marie-Lise

    2011-05-19

    In Luxembourg, viral hepatitis and HIV infection data in problem drug users (PDUs) are primarily based on self-reporting. Our study aimed to determine the prevalence of HAV, HBV, HCV and HIV infections in ever injecting (IDUs) and non-injecting drug users (nIDUs) including inherent risk factors analysis for IDUs. Secondary objectives were immunisation against HAV and HBV, referral to care and treatment facilities as well as reduction in risk behaviour. A nationwide, cross-sectional multi-site survey, involving 5 in-, 8 out-treatment and 2 prison centres, included both an assisted questionnaire (n = 368) and serological detection of HIV and Hepatitis A, B, C (n = 334). A response rate of 31% resulted in the participation of 310 IDUs and 58 nIDUs. Risk factors such as drug use, sexual behaviour, imprisonment, protection and health knowledge (HAV, HBV status and immunisations, HCV, HIV), piercing/tattoo and use of social and medical services were studied by means of chi2 and logistic models. Seroprevalence results for IDUs were 81.3% (218/268, 95%CI=[76.6; 86.0]) for HCV, 29.1% (74/254, 95%CI=[25.5;34.7 ]) for HBV (acute/chronic infection or past cured infection), 2.5% (5/202, 95%CI=[0.3; 4.6]) for HIV-1 and 57.1% (108/189, 95%CI=[50.0; 64.1]) for HAV (cured infections or past vaccinations). Seroprevalence results for nIDUs were 19.1% (9/47, 95%CI=[7.9;30.3]) for HCV, 8.9% (4/45, 95%CI=[0.6;17.2]) for HBV (acute/chronic infection or past cured infection), 4.8% (2/42, 95%CI=[-1.7;11.3]) for HIV-1 and 65.9% (27/41, 95%CI=[51.4;80.4]) for HAV. Prisoners showed the highest rates for all infections. Age, imprisonment and setting of recruitment were statistically associated with HCV seropositivity. Age, speedball career and nationality were significantly associated with HBV seropositivity. Only 56% of the participants in outpatient centres collected their serology results and 43 doses of vaccine against HAV and/or HBV were administered. Despite the existing national risk

    Among other things, the 1986 amendments to this law provide that Luxembourg nationality is granted to children born of a Luxembourg mother, rather than only of a Luxembourg father, and that the possibility of choosing Luxembourg nationality is available to a male foreigner married to a woman with Luxembourg nationality, rather than only to a female foreigner married to a man with Luxembourg nationality.

  16. Lost in Translanguaging? Practices of Language Promotion in Luxembourg ish Early Childhood Educatio

    Sascha Neumann

    2015-02-01

    Full Text Available Luxembourg maintains by far the largest proportion of foreign immigrants in Europe. This is also reflected in the population of children. About 50% of children under the age of four are foreign nationals. Accordingly, the question of how to deal with linguistic diversity represents one of the biggest challenges in the professional debate about early childhood education in Luxembourg. The article will refer to this issue on the basis of several insights stemming from an ethnographic study in Luxembourgish daycare centers which was conducted between 2009 and 2012 by the working group Early Childhood: Education and Care at the University of Luxembourg. The study explored practices professionals apply to come up with the superdiverse and translingual environment in order to meet the political expectation of promoting foreign children’s competences before they enter school. Based on the empirical investigations of everyday language use in center-based early childhood education, the article will not only characterize two different modes of language promotion (institutional monolingualization in one language and institutional monolingualization in several languages but also highlight the ambiguities of those language promotion practices which, although facing a translingual environment, are still based on a multilingual standard.

  17. Developing a phenological model for grapevine to assess future frost risk in Luxembourg

    Caffarra, A.; Molitor, D.; Pertot, I.; Sinigoy, P.; Junk, J.

    2012-04-01

    Late frost damage represents a significant hazard to grape production in cool climate viticulture regions such as Luxembourg. The main aim of our study is to analyze the frequency of these events for the Luxembourg's winegrowing region in the future. Spring frost injuries on grape may occur when young green parts are exposed to air temperature below 0°C. The potential risk is determined by: (i) minimum air temperature conditions and the (ii) the timing of bud burst. Therefore, we developed and validated a model for budburst of the grapevine (*Vitis vinifera)* cultivar Rivaner, the most grown local variety, based on multi-annual data from 7 different sites across Europe and the US. An advantage of this approach is, that it could be applied to a wide range of climate conditions. Higher spring temperatures were projected for the future and could lead to earlier dates of budburst as well as earlier dates of last frost events in the season. However, so far it is unknown if this will increase or decrease the risk of severe late frost damages for Luxembourg's winegrowing region. To address this question results of 10 regional climate change projections from the FP6 ENSEMBLES project (spatial resolution = 25km; A1B emission scenario) were combined with the new bud burst model. The use of a multi model ensemble of climate change projections allows for a better quantification of the uncertainties. A bias corrections scheme, based on local observations, was applied to the model output. Projected daily minimum air temperatures, up to 2098, were compared to the projected date of bud burst in order to quantify the future frost risk for Luxembourg.

    This study aimed to assess public attitudes in Japan to the promotion of genomic selection in crop studies and to examine associated factors. We analysed data from a nationwide opinion survey. A total of 4,000 people were selected from the Japanese general population by a stratified two-phase sampling method, and 2,171 people participated by post; this survey asked about the pros and cons of crop-related genomic studies promotion, examined people's scientific literacy in genomics, and investigated factors thought to be related to genomic literacy and attitude. The relationships were examined using logistic regression models stratified by gender. Survey results showed that 50.0% of respondents approved of the promotion of crop-related genomic studies, while 6.7% disapproved. No correlation was found between literacy and attitude towards promotion. Trust in experts, belief in science, an interest in genomic studies and willingness to purchase new products correlated with a positive attitude towards crop-related genomic studies.

    This study examined the association between nutritional awareness and diet quality, as indicated by energy density, dietary diversity and adequacy to achieve dietary recommendations, while considering the potentially important role of socioeconomic status (SES). Data were derived from 1351 subjects, aged 18-69 years and enrolled in the ORISCAV-LUX study. Energy density score (EDS), dietary diversity score (DDS) and Recommendation Compliance Index (RCI) were calculated based on data derived from a food frequency questionnaire. Nutritional awareness was defined as self-perception of the importance assigned to eating balanced meals, and classified as high, moderate, or of little importance. Initially, a General Linear Model was fit that adjusted for age, sex, country of birth, and body mass index (BMI). Furthermore, simultaneous contributions to diet quality of individual-level socioeconomic factors, education, and household income were examined across levels of nutritional awareness. Attributing high importance was associated inversely with energy density (p = 0.02), positively with both dietary diversity (p diet quality, with a minor component of variance explained by improved income. The impact of nutritional awareness on diet quality seems to be a promising area for both health promotion and health policy research.

  4. Geological and thermal exploration for an evaluation of the geothermal potential of Luxembourg

    Schintgen, Tom; Förster, Andrea

    2013-04-01

    In 2010, work has commenced on the evaluation of the geothermal potential of Luxembourg. The concept of this evaluation comprises several steps. Given the limited amount of geological data and the lack of petrothermal data as well as on crustal heat flow, in-depth studies are needed that allow a comprehensive insight into the shallow as well as deep thermal subsurface structure and thus to make temperature prognoses for the use of geothermal energy. Here we report the geological structure of the Mesozoic Trier-Luxembourg Basin (TLB) with its various lithological units as well as the geology of the underlying basement units. The thickness of the Mesozoic section increases from 400-500 m in the northeastern part of the basin to a maximum of 1100 m in the southern part of Luxembourg. New data on thermal parameters, such as the thermal conductivity (TC), radiogenic heat production (RHP) and porosity are presented for the major lithotypes of the TLB as well as of the underlying Paleozoic basement. These data originated from core samples (Mesozoic formations) and from sampling of outcrops of Luxembourg's surroundings (Paleozoic formations). Thus data are now available for an up to 13-km-thick succession of the upper crust, comprising the Lower Cambrian to the Middle Ordovician, the relatively thick Lower Devonian and the Triassic to Liassic of the TLB. For the remainder of the crust down to the Moho thermal properties are determined by translating seismic velocities into rock types and using average values for TC and RHP for these metamorphic and igneous rocks. Based on the new values of TC and a temperature log measured under thermal equilibrium in a 300-m deep borehole, surface heat flow was determined. These data form the basis for modeling the subsurface temperatures along two regional crustal cross sections, which cover most of the Rhenohercynian Zone of the Variscan orogenic belt. They extend from the Lower Paleozoic Stavelot Massif in the Belgian Ardennes in the

    Full Text Available

    Services provided for European citizens’ healthcare are not services like standard commercial services. Healthcare services need to be accessible, independent of the citizen’s economic or social background and should at the same time be available to all at the best possible quality level.

    The Luxembourg Declaration on Patient Safety recognizes these challenging fundamental principles. Patient safety is a key aspect for all European policy makers, as it is a vital question of equitable access to health care. Nevertheless we know that unfortunately a considerable amount of avoidable safety events still occur all across Europe!

    However differently organized our national health systems may be, it is vital to share experience and knowledge at a European level in order to be able to learn from the experiences of the different memberstates. No uniform solution can be found and decreed from the bottom down, nevertheless Europe can contribute and help to raise standards by a common effort. The Luxembourg Declaration is a launching pad for European progress in this field as it sets important goals and demonstrates the steps to be undertaken. It is a calling and gives us hope for measurable progress in the future.

  9. Ecological deficit and use of natural capital in Luxembourg from 1995 to 2009.

    Rugani, Benedetto; Roviani, Davide; Hild, Paula; Schmitt, Bianca; Benetto, Enrico

    2014-01-15

    Scarcity of natural resources and productive land is a global issue affecting the provision of goods and services at the country scale. This is particularly true for small regions with highly developed economies such as Luxembourg, which usually balance the chronic unavailability of resources (in particular with regard to fossil fuels) with an increasing demand of imported raw materials, energy and manufactured commodities. Based on historical time-series analysis (from 1995 to 2009), this paper determines the state of natural capital (NC) utilization in Luxembourg and estimates its ecological deficit (ED). Accordingly, solar energy demand (SED) and ecological footprint (EF) for Luxembourg have been initially calculated based on a recently developed country-specific environmentally extended input-output model. Thereafter, these indicators have been compared to the corresponding annual trends of potential NC (estimated using the emergy concept) and biocapacity, respectively. Results show that the trends in ED and in the use of NC in Luxembourg have not increased substantially during the years surveyed. However, the estimates also highlight that the NC of Luxembourg is directly and indirectly overused by a factor higher than 20, while circa 9 additional 'Luxembourg states' would be ideally necessary to satisfy the current land's requirements of the country and thus balance the impact induced by the EF. An in-depth analysis of the methodological advantages and limitations behind our modelling approach has been performed to validate our findings and propose a road map to improve the environmental accounting for NC and biocapacity in Luxembourg. © 2013.

    2011-07-01

    This publication provides a detailed look at the specific systems in Luxembourg for responding to an oil supply crisis. In 2007, the IEA published ''Oil Supply Security: Emergency Response of IEA Countries''. Rather than waiting for the completion of the current review cycle to renew this full publication, the IEA will provide updates to the country chapters as these become available following the specific country's review. The aim of series of publications is to provide an overview of the IEA oil emergency response system and a detailed look at the specific systems in each IEA country for responding to an oil supply crisis. The 2007 publication represented the findings of a five year review cycle of the emergency response mechanisms in IEA member countries. Since the 2007 publication, the IEA has started a new cycle of reviews which now includes reviewing gas emergency policies.

  11. Geological-uraniferous favourability of South America

    Stipanicic, P.N.

    1984-01-01

    The South American continent includes several metallogenic provinces some of which have excellent uranium possibilities. Basically, two types of lithological complex have contributed to this favourability: the large Precambrian shields covering about 5,500,000 km 2 and the crystalline Hercynian nesocratons with about 300,000 km 2 as source rocks. Only in Argentina and Brazil has continuous uranium exploration in South America been carried out, with moderate budgets, during the last twenty-five years. In the rest of South America the search for uranium has been performed intermittently and with limited resources. However, during recent years interest has increased and more continuous operation has been recorded in some countries (Bolivia, Colombia, Chile, Peru). It can be estimated that only 20% of the favourable areas have been explored fairly intensively in Argentina and Brazil, the two most advanced uraniferous countries. Nevertheless, the uranium possibilities of South America are proved by the resources of 250,000 t U already defined (in Argentina and Brazil) for the category of production cost below US $130/kg U. The speculative uranium potential of the continent was estimated by the International Uranium Resources Evaluation Project as between 770,000 and 1,500,000 t U. Within the South American geostructural framework, five main uraniferous geological areas have been defined on the basis of the geotectonic evolution of the continent, the succession of sedimentary and magmatic processes, and the participation in them of the endogenous and exogenous phases of the uranium geochemical cycle. In this paper the principal uranium metallogenic models occurring in the above five main areas are studied together with the uranium potential of each area. The possibility of uranium recovery from these sources in relation to the respective costs of production is briefly discussed

    Isovaleric aciduria (IVA), propionic aciduria (PA) and methylmalonic aciduria (MMA) are inherited organic acidurias (OAs) in which impaired organic acid metabolism induces hyperammonaemia arising partly from secondary deficiency of N-acetylglutamate (NAG) synthase. Rapid reduction in plasma ammonia is required to prevent neurological complications. This retrospective, multicentre, open-label, uncontrolled, phase IIIb study evaluated the efficacy and safety of carglumic acid, a synthetic structural analogue of NAG, for treating hyperammonaemia during OA decompensation. Eligible patients had confirmed OA and hyperammonaemia (plasma NH3 > 60 μmol/L) in ≥1 decompensation episode treated with carglumic acid (dose discretionary, mean (SD) first dose 96.3 (73.8) mg/kg). The primary outcome was change in plasma ammonia from baseline to endpoint (last available ammonia measurement at ≤18 hours after the last carglumic acid administration, or on Day 15) for each episode. Secondary outcomes included clinical response and safety. The efficacy population (received ≥1 dose of study drug and had post-baseline measurements) comprised 41 patients (MMA: 21, PA: 16, IVA: 4) with 48 decompensation episodes (MMA: 25, PA: 19, IVA: 4). Mean baseline plasma ammonia concentration was 468.3 (±365.3) μmol/L in neonates (29 episodes) and 171.3 (±75.7) μmol/L in non-neonates (19 episodes). At endpoint the mean plasma NH3 concentration was 60.7 (±36.5) μmol/L in neonates and 55.2 (±21.8) μmol/L in non-neonates. Median time to normalise ammonaemia was 38.4 hours in neonates vs 28.3 hours in non-neonates and was similar between OA subgroups (MMA: 37.5 hours, PA: 36.0 hours, IVA: 40.5 hours). Median time to ammonia normalisation was 1.5 and 1.6 days in patients receiving and not receiving concomitant scavenger therapy, respectively. Although patients receiving carglumic acid with scavengers had a greater reduction in plasma ammonia, the endpoint ammonia levels were

    2009-04-01

    Experimental hydrology focuses traditionally on field investigations at smaller spatial and temporal scales and research is driven by small-scale, detailed and complex investigations of densely instrumented research sites. However, to improve operational water management and protection of water resources at the river basin scale, it is necessary to study the hydrological processes across a range of scales. Empirical studies investigating catchment structure and functioning across multiple scales are still rare and urgently needed. Besides geomorphologic and climatic catchment descriptors, environmental tracers have been recognized as a fundamental tool in experimental hydrology to assess the scaling gap, as they provide an independent and integrative perspective of catchment functioning and scaling. A three year tracer study is being carried out in the Attert river basin in Luxembourg to identify how major controls of runoff generation change across scales and to investigate the spatial and temporal functioning of larger basins. The mesoscale (300 km²) Attert catchment is located in the Midwestern part of Luxembourg and lies at the transition zone of contrasting bedrock lithology that is a major control for runoff generation: The Northern part is characterized by Devonian schist of the Ardennes massif, while sedimentary deposits of sandstone and marls dominate in the Southern part of the basin. Major hydrochemical tracers including stable water isotopes were grab sampled fortnightly and, where possible, also event-based at 13 nested stream locations ranging in size from 0.5 to 300 km² throughout the basin. Results using Deuterium and a range of hydrochemical tracers confirm the major role of bedrock lithology for runoff response of different geological parts of the basins: Hydrological response of schistose basins is characterized by seasonal variation and a delayed shallow groundwater component originating from a saprolitic zone, sandstone basins exhibit a

  17. First Zenith Total Delay and Integrated Water Vapour Estimates from the Near Real-Time GNSS Data Processing Systems at the University of Luxembourg

    2012-04-01

    Since September 2011 the University of Luxembourg in collaboration with the University of Nottingham has been setting up two near real-time processing systems for ground-based GNSS data for the provision of zenith total delay (ZTD) and integrated water vapour (IWV) estimates. Both systems are based on Bernese v5.0, use the double-differenced network processing strategy and operate with a 1-hour (NRT1h) and 15-minutes (NRT15m) update cycle. Furthermore, the systems follow the approach of the E-GVAP METO and IES2 systems in that the normal equations for the latest data are combined with those from the previous four updates during the estimation of the ZTDs. NRT1h currently takes the hourly data from over 130 GNSS stations in Europe whereas NRT15m is primarily using the real-time streams of EUREF-IP. Both networks include additional GNSS stations in Luxembourg, Belgium and France. The a priori station coordinates for all of these stem from a moving average computed over the last 20 to 50 days and are based on the precise point positioning processing strategy. In this study we present the first ZTD and IWV estimates obtained from the NRT1h and NRT15m systems in development at the University of Luxembourg. In a preliminary evaluation we compare their performance to the IES2 system at the University of Nottingham and find the IWV estimates to agree at the sub-millimetre level.

  18. Determination of favourable areas for uranium prospecting in Bolivia

    Pardo, E.

    1981-01-01

    The most prominent geological, lithological, stratigraphic, orogenic, metallogenetic, palaeogeographic and geochemical features favourable for the concentration of uranium deposits in Bolivia are described. This is a generalized study of the features mentioned above and should provide guidelines for eventual better understanding of the geology of Bolivia in general and that of uranium in particular. The purpose here is to demonstrate rational planning, which should be followed by the determination of favourable areas for uranium exploration, by the Bolivian Nuclear Energy Commission/Comision Boliviana de Energia Nuclear (COBOEN), and to provide basic information for the drawing up of contracts with foreign and/or national organizations interested in investing in uranium exploration.

  19. Control of radioactivity at the Luxembourg steel-making facilities

    Werner, C.

    1999-01-01

    The Luxembourg steel industry has a yearly capacity of close to 3 million tonnes of raw steel produced from scrap at three electric arc furnace steel-making plants. It has introduced in 1994 a comprehensive system of measuring devices to prevent radioactive material from being introduced into its meltshops. Detection equipment has been installed at the road and railroad accesses to the three plants. Further to the controls of incoming scrap, radioactivity is monitored on both the steel and the slag samples of each heat produced at the plants. This measure is taken in order to detect any incident involving the melting of a radioactive source that might have escaped the controls of incoming material as soon as possible. The triple purpose of these controls is: (i) to protect the personnel of the steel making plants from radiation hazards; (ii) to maintain the integrity of the equipment; and (iii) to assure integrity of the products. The presentation describes the possible origins of radioactive contamination in steel scrap as well as the behaviour in the steel making process of the different radionuclides that can be expected to be introduced into the steel making vessels through steel scrap. Together with the government agency for radiation protection, procedures have been developed for the management of any event of detection of radioactivity in the plants and to assure optimum availability of the measuring equipment. These procedures are described and commented in the presentation. The presentation includes also a report on the experience from 4 years of monitoring, during which more than 10 million tonnes of scrap have passed the gates of the steel-making plants of ProfilARBED and ARES.

    Carter, H Ballentine

    2011-12-01

    What's known on the subject? and What does the study add? Most men who are diagnosed with favourable-risk prostate cancer undergo some form of active intervention, despite evidence that treatment will not improve health outcomes for many. The decision to undergo treatment after diagnosis is, in part, related to the inability to precisely determine the long-term risk of harm without treatment. Nevertheless, physicians should consider patient age, overall health, and preferences for living with cancer and the potential side effects of curative treatments, before recommending a management option. This is especially important for older men, given the high level of evidence that those with low-risk disease are unlikely to accrue any benefit from curative intervention. What is known on the subject: Over treatment of favourable-risk prostate cancer is common, especially among older men. What does the study add: A review of the natural history of favourable-risk prostate cancer in the context of choices for management of the disease. • The management of favourable-risk prostate cancer is controversial, and in the absence of controlled trials to inform best practice, choices are driven by personal beliefs with resultant wide variation in practice patterns. • Men with favourable-risk prostate cancer diagnosed today often undergo treatments that will not improve overall health outcomes. • A shared-decision approach for selecting optimal management of favourable-risk disease should account for patient age, overall health, and preferences for living with cancer and the potential side effects of curative treatments. © 2011 THE AUTHOR.

  1. Transnational Skills Development in Post-Industrial Knowledge Economies: The Case of Luxembourg and The Greater Region

    Graf, Lukas; Gardin, Matias

    2018-01-01

    Luxembourg exhibits strong transnational traits within its skills regime, defying any neat fit with existing educational typologies. It is characterised by its high-skill economy, cross-cultural characteristics, and central location within the European Union. As such, Luxembourg has developed a hybrid strategy of responding to labour market…

  8. Favourable environments for uranium occurences in Brazil

    Santos, L.C.S. dos

    1980-01-01

    Based on the present knowledge of Brazilian Precambrian geology, an attempt is made to divide Precambrian rocks into different regions according to their favourability criteria for uranium concentrations. Paleozoic and Mesozoic occurrences are also mentioned. They are mainly associated with large sedimentary basins. Brazilian uranium occurrences can be grouped into the following environments: (1) Metaconglomerates; (2) Metasomatic rocks (associated with albitization); (3) Vein type; (4) Sandstone type and (5) Intrusive alkalic rock. Upper Proterozoicas folding regions related to mobile belts and large Precambrian unconformities are good targets for uranium exploration in Brazil. (Author) [pt

    The Kyoto protocol has established an accounting system for national greenhouse gas (GHG) emissions according to a geographic criterion (producer perspective), such as that proposed by the IPCC guidelines for national GHG inventories. However, the representativeness of this approach is still being debated, because the role of final consumers (consumer perspective) is not considered in the emission allocation system. This paper explores the usefulness of a hybrid analysis, including input–output (IO) and process inventory data, as a complementary tool for estimating and allocating national GHG emissions according to both consumer- and producer-based perspectives. We assess the historical GHG impact profile (from 1995 to 2009) of Luxembourg, which is taken as a case study. The country's net consumption over time is estimated to generate about 28,700 Gg CO{sub 2}e/year on average. Compared to the conventional IPCC inventory, the IO-based framework typically shows much higher emission estimations. This relevant discrepancy is mainly due to the different points of view obtained from the hybrid model, in particular with regard to the contribution of imported goods and services. Detailing the GHG inventory by economic activity and considering a wider system boundary make the hybrid IO method advantageous as compared to the IPCC approach, but its effective implementation is still limited by the relatively complex modeling system, as well as the lack of coordination and scarce availability of datasets at the national level. - Highlights: • GHG emissions for Luxembourg are assessed using hybrid input–output (IO) modeling. • Consumer and producer perspectives are compared for the period 1995–2009. • IO-based GHG profiles are remarkably higher than traditional IPCC inventorying. • IO-based GHG accounting presents some advantages but is limited in implementation. • Key-aspects of IPCC and IO-based methods are extensively investigated and compared.

  11. Four arguments in favour of nuclear power

    Pearce, D.

    1994-01-01

    The first argument in favour of nuclear power is scarcity of energy supplies. In about 40 years time, the world will face shortages of natural gas, oil and uranium. Recoverable reserves of coal are very great, but coal creates the highest environmental damage. A balanced portfolio is the second argument. If all energy sources are potentially scarce, then all energy sources must be developed, subject to environmental impact. This leads to the third argument in support of nuclear power, its expansion would contribute to combating the risk of global warming as indeed would the expansion of renewable sources and other low carbon technologies. Fourthly, nuclear power can make a significant contribution to the control of acidic emissions. While nuclear power is not without its own problems of risk, liability and public acceptance, it has some clear advantages over other fuels. It has, at the very least, to be a substantial part of the transitional phase towards a renewable energy world. (UK)

    2003-01-01

    Morphologic criteria which might help to support the need for a preventive strategy for early detection of rectal cancer were analysed. Population-based data on rectal adenomas with high-grade dysplastic changes (n = 199) and invasive adenocarcinomas (n = 912) registered by the national Morphologic Tumour Registry (MTR) and diagnosed in a central department of pathology in Luxembourg between 1988 and 1998 were considered. The analysis concerned time trends in frequency, crude incidence, tumour-stage, the rectal 'high-grade' adenoma/invasive adenocarcinoma-ratio and the survival rates. Histopathological tumour-stage parameters (UICC/AJCC, 1997) in a consecutive series of 641 resected rectal cancers and their relationship with the observed patient survival are investigated. The majority of invasive adenocarcinomas are diagnosed at a late stage (i.e. Stage II and III) into contrast with the highly significant increase (355 %) in frequency of rectal high-grade adenomas (Stage 0). During the two-time periods 1988–1992 and 1994–1998 Stage I and Stage IV-cases decreased by 11 % and 47 % respectively. Tumour-stage correlates with prognosis. The rectal high-grade adenoma / invasive adenocarcinoma-ratio improved significantly over the last five years. Over the study period, there has been a highly significant rise in the incidence of resected rectal adenomas with high-grade intraepithelial neoplasia. The ratio of early tumours to invasive cancers has risen while the numbers of colonoscopies and rectoscopies remained unchanged respectively decreased. As the number of advanced tumour-stages remained stable, mass-screening procedures focusing on the fifty to sixty age group should be reinforced

    2008-01-01

    Luxembourg has been conducting a breast cancer screening programme since 1992, like a large number of other European countries, as early detection and treatment of breast cancer have been proven to reduce mortality. The majority of these screening programmes are based on analogue X-ray technology and have optimised their organisation of transporting, archiving and reading with respect to films. Last decade is marked by enormous developments in digital mammography. Different technologies such as flat panel-, computed radiography- and scanning systems became available. Digital mammography is expected to have a major impact on quality and organisation of breast cancer screening programmes. Screening programmes are now faced with a huge challenge of incorporating the digital technology, including implementation of electronic image exchange, conception of new electronic work-flow, establishing adapted quality assurance programmes and training of radiologists and technical personnel. Initial experiences of the Luxembourg approach in organising digital mammography screening and its quality assurance are reported. (authors)

    Full Text Available The aim of the study is conducting methodologically sound, cross-sequential analyses of the creativity development of children attending different school systems. Culture-free tests of creativity (ideational fluency and flexibility and intelligence were administered in 5 cohorts (two kindergarten and first three elementary school years, which were retested in three consecutive years. Samples include 244 Luxembourg and 312 German children enrolled in educational systems with obligatory kindergarten and 6-year comprehensive elementary school versus optional kindergarten, 4-year comprehensive elementary school and educational placement thereafter. Results demonstrate (1 linear increases in intelligence, (2 declines of divergent performances after school enrollment in both samples, (3 increases in divergent performances up to the 5th elementary school year in Luxembourg and up to the 3rd elementary school year in Germany (i.e., the next to last school year before educational placement followed by a second creativity slump. Cross-sequential results confirm discontinuities in the development of divergent productions in childhood.

    Over the last two decades time trends in incidence rates of colorectal cancer, changes in the proportions of stage at diagnosis and changes in the anatomic sub-site distribution of colon cancers have been reported in some European countries. In order to determine a strategy for early detection of colon cancer in the Grand-Duchy of Luxembourg, all consecutive colon adenocarcinomas diagnosed during the period 1988–1998 at a nation-wide level were reviewed. The population-based data of the national Morphologic Tumour Registry report all new high-grade adenomas (i.e. high-grade intraepithelial adenomatous neoplasias) and all consecutive new invasive adenocarcinomas of the colon diagnosed in the central department of pathology. Attention has been focused on variations in incidence, stage, anatomical site distribution and survival rates. Rectal cancers were excluded. Over the study period, 254 new colonic high-grade adenomas and 1379 new invasive adenocarcinomas were found; the crude incidence rates of colon adenocarcinomas grew steadily by 30%. Comparing the two 5-year periods 1988–1992 and 1994–1998, the crude incidence rates of high-grade adenomas (stage 0) rose by 190%, that of stage I cases by 14.3%, stage II cases 12.9% and stage III cases 38.5%, whereas the crude incidence rates of stage IV cases decreased by 11.8%. The high-grade adenoma/adenocarcinoma ratio increased. The right-sided colonic adenocarcinomas in elderly patients (>69 years) increased by 76%. The observed survival rates correlated with tumour stages. The overall observed 5-year survival rate (stage I-IV) was 51 ± 3% (95% confidence interval). The increasing incidence rates of colon adenocarcinomas, the persistence of advanced tumour stages (stage III), the mortality rates which remain stable, and the changing trends in the age- and sub-site distribution underline the need for preventive measures at the age of 50 in asymptomatic patients to reduce mortality from colo(rectal) cancer

  18. Favourability towards electric utilities jumps 10 per cent in 1997

    Anon.

    1997-01-01

    A recent survey of public opinion has shown that 85 per cent of the public view their electric utility company favourably. This represents a 10 per cent increase over last year. A survey of 4,090 Canadians was conducted which looked at the perceptions of the value of electricity services compared to telephone, natural gas, banking, and home insurance services. The study showed that Canadian electric utility companies are viewed as positively as the telephone companies and almost as favourably as the banks. Some 71 per cent of respondents reported that the value they receive from their electric utility is excellent or good. Lower prices, better customer services and increased research into alternative power sources were among the benefits that Canadians perceive would result from a more competitive electricity sector. Some misgivings about deregulation included a belief that there would be less attention to environmental concerns and more outages. Four per cent of the respondents said they would 'definitely' switch to an alternative supplier of electricity, while 25 per cent said they would 'probably' switch to an alternative supplier of electricity. 2 tabs

    This report is a synthesis of the possibilities of CO{sub 2} storage in the Spanish subsurface. Compilation and analysis of geological information has been carried out, looking at surface and subsurface, in order to make a pre-selection of potential favourable units for CO{sub 2} storage, taking in account that each of this storages needs a confining formation to seal the storage. Before the storage selection, a general description of the great geological units of the Iberian Peninsula is done. Afterwards, borehole logging from petroleum exploration is analysed in these units, formations and areas of interest. The aim is to finally obtain a description of selected units and their possibilities of CO{sub 2} storage. (Author) 17 refs.

  20. An unusual discovery of human remains from the medieval church of Grevenmacher (Luxembourg).

    Trautmann, Bernd; Bis-Worch, Christiane

    2017-12-01

    The occurrence of burned human remains on a Christian burial ground is very rare in medieval Europe. Therefore, the discovery of a complex consisting of commingled burned and unburned human bones within the church of Grevenmacher (Luxembourg) is from special interest for anthropological as well as archaeological research. In the current paper we present methods for a comprehensive analysis for such an exceptional case connected with the question if this bone accumulation represents a form of funerary custom or if other factors lead to its composition. Thereof, two possible scenarios for the occurrence of this unusual composition were created and discussed.

    Rabid bats are regularly reported in Europe, especially in countries that have implemented a bat surveillance network. In May 2013, bat rabies was evidenced for the first time in Luxembourg (southern city of Differdange). The rabies virus, an EBLV-1b strain, was diagnosed in a serotine bat that bit a 29-year-old male person while he was asleep. The man received rapidly a post-exposure RABV treatment and was put under strict medical supervision. © 2013 Blackwell Verlag GmbH.

    2005-01-01

    As a consequence of their unique positioning and 3,5:1 plan ratio, the proposed twin 103m buildings of the latest expansion of the European Court of Justice (Luxembourg) led to the commissioning of a comprehensive set of wind-tunnel tests. Experimental testing and numerical analyses showed...... the buildings to be susceptible to unacceptably large wind-induced accelerations at the top levels. To mitigate these vibrations, a Tuned Liquid Damper (TLD) array is proposed and designed for both buildings. With an optimal design of the TLD array, total maximum reductions in top-level accelerations are found...

    This study investigates whether biofuel policies or favourable taxation of electric cars should be employed to satisfy a green house gas emission target connected to private transport within the Norwegian economy. The study shows that implementation of biofuel generates a welfare gain in the presence of the current favourable taxation of electric cars in Norway. Implementation of biofuels, however, generates a welfare loss when the tax rate on purchase of electric cars is increased to the ave...

    2010-01-01

    Financing of the Luxembourg pension system is based on a pay-as-you-go system and hence on an intergenerational contract. As is the case for most other European countries, this system will be exposed to the effects of demographic aging over the coming decades. The aim of this paper is to evaluate the impact of this demographic deficit on the long term sustainability of the Luxembourg pension system. We proceed in two steps. In a first step, we highlight the evolution of salaries in ...

  7. Global warming favours light-coloured insects in Europe

    Zeuss, Dirk; Brandl, Roland; Brändle, Martin; Rahbek, Carsten; Brunzel, Stefan

    2014-01-01

    Associations between biological traits of animals and climate are well documented by physiological and local-scale studies. However, whether an ecophysiological phenomenon can affect large-scale biogeographical patterns of insects is largely unknown. Insects absorb energy from the sun to become mobile, and their colouration varies depending on the prevailing climate where they live. Here we show, using data of 473 European butterfly and dragonfly species, that dark-coloured insect species are favoured in cooler climates and light-coloured species in warmer climates. By comparing distribution maps of dragonflies from 1988 and 2006, we provide support for a mechanistic link between climate, functional traits and species that affects geographical distributions even at continental scales. Our results constitute a foundation for better forecasting the effect of climate change on many insect groups. PMID:24866819

  8. Main elements in favour of an immediate decommissioning

    Cregut, A.

    1985-01-01

    After a presentation of the elements to be taken into consideration when undertaking a comparative study of the diverse possible solutions for the future of a shut down nuclear reactor, this outlines the advantages of simultaneously decommissioning and conducting final shut down operations. It is clarified that in a real situation the benefits of demonstration and judgement on the technical solutions adopted are arguments in favour of this approach but that this is only true for the first case. The advantages of this approach in a systematic manner are then developed. In conclusion, the advantages associated with this approach are theoretically beyond question and it should not be rejected a priori. However, if it is a question of taken a decision on the future of a nuclear installation, it is necessary to quantify and compare the advantages and disadvantages of other approaches in order to make the best choice

  9. Delineating spring recharge areas in a fractured sandstone aquifer (Luxembourg) based on pesticide mass balance

    Farlin, J.; Drouet, L.; Gallé, T.; Pittois, D.; Bayerle, M.; Braun, C.; Maloszewski, P.; Vanderborght, J.; Elsner, M.; Kies, A.

    2013-06-01

    A simple method to delineate the recharge areas of a series of springs draining a fractured aquifer is presented. Instead of solving the flow and transport equations, the delineation is reformulated as a mass balance problem assigning arable land in proportion to the pesticide mass discharged annually in a spring at minimum total transport cost. The approach was applied to the Luxembourg Sandstone, a fractured-rock aquifer supplying half of the drinking water for Luxembourg, using the herbicide atrazine. Predictions of the recharge areas were most robust in situations of strong competition by neighbouring springs while the catchment boundaries for isolated springs were extremely sensitive to the parameter controlling flow direction. Validation using a different pesticide showed the best agreement with the simplest model used, whereas using historical crop-rotation data and spatially distributed soil-leaching data did not improve predictions. The whole approach presents the advantage of integrating objectively information on land use and pesticide concentration in spring water into the delineation of groundwater recharge zones in a fractured-rock aquifer.

    This contribution is based on a study dealing with the limitation or withdrawal of ownership rights to real estates in favour of the mining industry. All EU countries are included as of the year 2006. The interventions of the state concern ensuring entry to other people's lands to carry out exploration activities and restraining the proprietary rights of landowners in favour of mining, including expropriation. The countries where mining legislation does not cover state interventions are also presented.

  11. Natural selection can favour 'irrational' behaviour.

    McNamara, J M; Trimmer, P C; Houston, A I

    2014-01-01

    Understanding decisions is the fundamental aim of the behavioural sciences. The theory of rational choice is based on axiomatic principles such as transitivity and independence of irrelevant alternatives (IIA). Empirical studies have demonstrated that the behaviour of humans and other animals often seems irrational; there can be a lack of transitivity in choice and seemingly irrelevant alternatives can alter decisions. These violations of transitivity and IIA undermine rational choice theory. However, we show that an individual that is maximizing its rate of food gain can exhibit failure of transitivity and IIA. We show that such violations can be caused because a current option may disappear in the near future or a better option may reappear soon. Current food options can be indicative of food availability in the near future, and this key feature can result in apparently irrational behaviour.

    Controls of geology and topography on hydrological metrics, like summer low flow (Grant and Tague, 2004) or dynamic storage (Sayama et al., 2011), have been identified in nested catchment experiments. However, most tracer-based studies on streamflow generation have been carried out in small (10 km2) homogenous catchments (Klaus and McDonnell, 2013). The controlling effects of catchment physiography on how catchments store and release water, and how this eventually controls stream isotope behaviour over a large range of scale are poorly understood. Here, we present results from a nested catchment analysis in the Alzette River basin (Luxembourg, Europe). Our hydro-climatological network consists of 16 recording streamgauges and 21 pluviographs. Catchment areas range from 0.47 to 285 km2, with clean and mixed combinations of distinct geologies ranging from schists to marls, sandstone, dolomite and limestone. Our objective was to identify geological controls on (i) winter runoff ratios, (ii) maximum storage and (iii) isotopic signatures in streamflow. For each catchment we determined average runoff ratios from winter season precipitation-discharge double-mass curves. Maximum catchment storage was based on the dynamic storage change approach of Sayama et al. (2011). Changes in isotopic signatures of streamflow were documented along individual catchment flow duration curves. We found strong correlations between average winter runoff ratios, maximum storage and the prevailing geological settings. Catchments with impermeable bedrock (e.g. marls or schists) were characterised by small storage potential and high average filling ratios. As a consequence, these catchments also exhibited the highest average runoff ratios. In catchments underlain by permeable bedrock (e.g. sandstone), storage potential was significantly higher and runoff ratios were considerably smaller. The isotopic signatures of streamflow showed large differences between catchments. In catchments dominated by

  15. Structural Health Monitoring Using Wireless Technologies: An Ambient Vibration Test on the Adolphe Bridge, Luxembourg City

    2012-01-01

    Full Text Available Major threats to bridges primarily consist of the aging of the structural elements, earthquake-induced shaking and standing waves generated by windstorms. The necessity of information on the state of health of structures in real-time, allowing for timely warnings in the case of damaging events, requires structural health monitoring (SHM systems that allow the risks of these threats to be mitigated. Here we present the results of a short-duration experiment carried out with low-cost wireless instruments for monitoring the vibration characteristics and dynamic properties of a strategic civil infrastructure, the Adolphe Bridge in Luxembourg City. The Adolphe Bridge is a masonry arch construction dating from 1903 and will undergo major renovation works in the upcoming years. Our experiment shows that a network of these wireless sensing units is well suited to monitor the vibration characteristics of such a historical arch bridge and hence represents a low-cost and efficient solution for SHM.

  16. The Limits of Polycentrism at the City-regional Scale: The case of Luxembourg

    Antoine Decoville

    2014-02-01

    Full Text Available Over the last fifteen years, promoters of the European spatial planning policy have presented polycentrism as the most promising strategy for answering the challenge of a more even spatial development. However, there is still no empirical evidence proving that this conceptual tool is adaptable to all scales. In this paper, we propose two different approaches of urban hierarchy with regards to its capacity to structure spatial development at a city-regional scale: the Grand Duchy of Luxembourg. The first one depicts a classical urban hierarchy based on the location of urban amenities. The second one, which takes into account the accessibility to these amenities, shows the polycentric model in a more nuanced manner. Our results underline the differences between these two models and call for caution with respect to the adoption of the polycentric model at this spatial scale, since it could potentially lead to an increase in urban sprawl.

  17. Luxembourg in the Early Days of the EEC: Null Player or Not?

    Alexander Mayer

    2018-05-01

    Full Text Available Voters whose yes-or-no decision never makes a difference to the outcome in a simple voting game are known as “null players”. Luxembourg’s role in the Council of Ministers during the first period of the European Economic Community (EEC is often cited as a real-world case. The paper contrasts the textbook claim that Luxembourg was a null player with a more comprehensive picture of Luxembourg’s role in EEC’s voting system. The assessment of Luxembourg’s voting power is sensitive to the role played by the European Commission in the decision-making procedure and the measurement concepts underlying power evaluations.

  18. Using stable isotopes to estimate and compare mean residence times in contrasting geologic catchments (Attert River, NW Luxembourg)

    Martínez-Carreras, N.; Fenicia, F.; Frentress, J.; Wrede, S.; Pfister, L.

    2012-04-01

    In recent years, stable isotopes have been increasingly used to characterize important aspects of catchment hydrological functioning, such as water storage dynamics, flow pathways and water sources. These characteristics are often synthesized by the Mean Residence Time (MRT), which is a simple catchment descriptor that employ the relation of distinct stable isotopic signatures in the rainfall input and streamflow output of a catchment that are significantly dampened through sub-surface propagation. In this preliminary study, MRT was estimated in the Attert River catchment (NW Luxembourg), where previous studies have shown that lithology exerts a major control on runoff generation. The Attert catchment lies at the transition zone of contrasting bedrock lithology: the Northern part is characterized by Devonian schist of the Ardennes massif, while sedimentary deposits of sandstone and marls dominate in the south of the catchment. As a consequence of differing lithologic characteristics, hydrological processes change across scales. The schistose catchments exhibit a delayed shallow groundwater component, sandstone catchments have slow-responding year-round groundwater component, whereas flashy runoff regimes prevails in the marly catchments. Under these circumstances, the MRTs are expected to vary significantly according to lithology, and provide additional understanding in internal catchment processes and their scale dependencies. In order to test this, bi-weekly monitoring of rainfall and discharge stable water isotope composition (oxygen-18 and deuterium) has been carried out since 2007 in 10 nested sub-catchments ranging in size from 0.4 to 247 km2 in the Attert catchment. MRT was estimated using different lumped convolution integral models and sine wave functions with varying transit times distributions (TTDs). TTDs were evaluated through calibration. Further research efforts will deal with the application of conceptual models to simulate and compare TTD, using

  20. Soil mechanical properties of MBT waste from Luxembourg, Germany and Thailand

    Pattaraporn Pimolthai

    2014-12-01

    Full Text Available Mechanical and biological treatments (MBT of waste have become well known in Europe and Asia. The maximum particle size of waste is reduced by the removal of larger plastic materials from municipal solid waste during mechanical processing. The mechanical properties of the MBT waste are significantly changed by this process. An effective treatment system can lead to a better quality of output materials which do not cause environmental problems. This paper shows the comparative mechanical properties of MBT wastes from Luxembourg, Germany and Thailand. This research focused on the smaller 10 mm-fraction of MBT samples, in order to describe and evaluate the potential application of the small size material as a cover liner in landfill sites. Therefore the smaller 10 mm-fraction of MBT samples were tested for geotechnical properties. The small size waste particles were analysed in laboratory tests in order to determine their particle size, particle shape, compaction, permeability, shear strength, porosity and water absorption capacity, including comparison with the properties of soil material. The results showed that reduced particles were likely to act as a compact, low permeable material with a high potential for water absorption. The amount of remaining fibre and foil components in the materials cause different mechanical and hydraulic behaviours in the samples. The leachate of MBT samples showed very low concentrations of chemical oxygen demand, ammonium, and heavy metals, compared to the landfill leachate of untreated waste.

  1. Can corruption favour growth via the composition of government spending?

    Sugata Ghosh; Andros Gregoriou

    2010-01-01

    In an endogenous growth model with two public goods, we analytically derive the optimal composition of government spending in the presence of corruption. Although corruption results in a loss of productivity per se, an increase in corruption in the category of public spending that is harmed relatively more by corruption could have a favourable effect on growth, as it would encourage a benevolent government to divert spending towards the public good that is more productive, net of corruption.

    1977-12-01

    Singapore's fairly small size belies its wealth which comes not from production and use of its own raw materials including mineral products, but from importing raw materials and using them in manufacturing and refining. The state has a granite core exposed in the center of the island covered on the west by quartzites and shales, and on the east by recent detritus. There is no mining industry and no uranium potential is assigned to Singapore. (author)

    1977-10-01

    The Italian Republic comprises a 1200 - Km - long peninsula ex- tending from southern Europe into the Mediterranean Sea, and a number of adjacent islands, among which the principals are Sicily and Sardinia. The total area is in excess of 300,000 Sq.Km, the islands account for some 50, 000 Sq.Km. From a physiographic and morphologic point of view, Italy mainly consists of the Alpine region and the Po valley to the North and of the Appennine range and small Coastal plains to the Centre and South. Plains occupied only 20% of the total area, hills and mountains, up to 4,810 m of elevation, contribute almost equally to the remaining 80%. The most promising uranium mineralizations have been found in the Bergamasc Alps, near the small town of Novazza. Pitchblende and minor sphalerite (formation temperature, 80 deg. - 100 deg. C) occur disseminated in volcanics of permian age. The host rocks at the Novazza uranium deposit, consist of an acid ignimbrite with cineritic texture. The rocks have been affected by metasomatism which brought abundant neo-formation minerals such as silica, sericite, carbonates and minor adularia, albite and muscovite. The reasonably assured resources of the Novazza deposit have been estimated to be 1,200 ton of U having a grade of 900 p.p.m. U. Estimated additional resources are 1,000 ton U. Production is scheduled to start in 1980

    1976-12-01

    Although Afghanistan has an extent of some 650,065 square kilometres, only a very small proportion of it has been surveyed for uranium, and that only at the preliminary reconnaissance stage. Earlier work by bi-lateral teams identified a number of small uranium anomalies and occurrences and more recently (1974-75) an IAEA geologist discovered evidence of uranium mineralisation in the Neogene - Lower Pleistocene continental sediments of the Jalalabad Basin to the east of Kabul. The I.A.E.A. expert outlined three areas totalling 20,000 km where systematic uranium exploration would be justified. Up to the present no positive programme has been agreed. On very tenuous evidence a Speculative Potential of 2000 tonnes U 3 O 8 is suggested for Afghanistan. (author)

  5. International Uranium Resources Evaluation Project (IUREP) national favourability studies: Greece

    1977-10-01

    Greece, with an area of 131,944 km 2 , has been actively explored since 1971 under a programme of co-operation with UNDP and IAEA on which close to US $1 million have been spent so far. The programme is focused on the Rhodope Precambrian massif, which is the most attractive structural unit from the geological point of view. The indications available at present, and which have been known for a long time, are also to be found in this unit. They are associated either with Tertiary continental volcanism or with detritic sediments in basins covering this massif. So far there is no evidence of their being of any economic value. The paucity of data available on the basement of the Rhodope precludes any prediction as to the possibility of its containing Pre-cambrian uranium mineralizations. One might perhaps think in terms of mineralizations of the alaskite or alkaline complex type, or also of vein-type deposits. But it is primarily in the deposits associated with tertiary trachy-rhyolitic volcanism that we have most confidence, especially in the Rhodope massif and the Vardar region but possibly elsewhere in the Hellenides as well. All things considered, we place Greece in Group 2 of the IUREP classification. (author)

    1977-11-01

    Finland covers an area of 337,000 skm. One third of the country lies north of the northern polar circle. 31,613 skm are covered by lakes. 71% of the landscape are covered by coniferous -wood. Climatlcal conditions are continental. The topography of the country is gently rolling with highest elevations of 300 m in the northern part. The most interesting geological units for uranium are Karelian, marginal meta-sediments, mainly quarzites and conglomerates but also schists. These schists are intruded by orogenlc plutonic rocks which are 1800-My-old. Potassium granites are common adjacent to the contact of the Pre-karelian basement (2500 My). In addition to these geological environment uranium and thorium minerals have been found in a large carbonatite in northern Finland, which is explored now

    1977-12-01

    Uranium occurrences and resources - To date the uranium identified in Belgium is limited to a number of occurrences and none of these have as yet proved significant from a reserve or resource viewpoint. The main uranium occurrences ares (1) In the Upper Cambrian graphite schists corresponding to the culm of Sweden small zones are found (30 - 50 cm thick) with an average of 20 ppm uranium. (2) Near Vise at the base of the Carboniferous the Visean formation is discordantly superimposed on the Permian (Frasnian) and overlain by shales and phyllites. Solution pockets at the boundary contain phosphatic lenses that contain uranium values of up to 200 ppm. Autunite and Torbernite are the main uranium minerals associated with a number of complex phosphatic minerals. Within the Chalk (Maestrichtien) of the Mons basin, that is mainly in the Ciply - St. Symphorien and Baudow district. Here is found enrichment of uranium up to 140 ppm over large areas related to phosphatic chalk. The thickness of the zone varies from a few to 20 metres. However, as the P 2 O 5 content is not high enough for the deposits to be exploited at present for phosphate there is little possibility of the uranium being concentrated at high enough levels to be exploited for itself alone. (4) Near to Vielsalm (in the Stavelot Massif) are some thin quartz veins containing small amounts of copper and uranium minerals (Torbornite). Values of up to 70 ppm are recorded. (5) A number of low uranium values are recorded associated with phosphatic nodules and zones in the Lower Pleistocene and Tertiary

    1977-11-01

    Bahrain consists of limestone, sandstone and marl of Cretaceous and Tertiary ages. The potential for discoveries of uranium is very limited and thus the Speculative potential is placed in the category of less than 1000 tonnes uranium. (author)

    Sikkim is a country in the eastern Himalayas and is bound on the west by Nepal, on the north by Tibet, on the east by Bhutan and on the south by India. Precambrian Darjeeling gneiss forms the rim of the amphitheatre while schists of Late Precambrian to Lower Paleozoic rocks form tee habital interior. A small outcrop of carboniferous to Permain methomorphic rocks is preserved in the Tista Basin as well in a thin outcrop trust upon fluvitile beds of Sivalik which is mostly of Pliestocene age. Imbricate thrusts have stacked the rocks in a vast heap where reverse metamorphism is common. Ni information is available concerning uranium occurrences and resources as well as past and present explorations. The uranium potential of Sikkim is almost zero

    1978-02-01

    Brunei is a very small country consisting of only 5,800 sq km, and with only 150,000 people. Its main mineral products are crude oil and natural gas. It is hot and humid throughout the year being located only 4 degrees north of the equator on the island of Borneo. The sultanate of Brunei contains very thick sediments, some of which probably have the characteristics of a good uranium host rock for sandstone type deposits, but tacking a classic source, the uranium potential is minimal. Potential for other types of uranium deposits is likewise considered minimal. Therefore Brunei is assigned a potential in category 1 (less than 1000 tonnes U). (author)

    1977-11-01

    The Chaine Annamatique represents the last of the three orogenic episodes that shook Indochina and forms most of Vietnam's boundary with Laos, In south Vietnam the mountains which have a north-south trend are formed of granites, gneisses and mica schists and are inseparable from the anti-hercynian formations. Iron ore, gold, lead, copper, tin, wolfraun, bismuth and molybdenium minerals are found. Plans had been made in 1960 to prospect for uranium but no information is available on whether that work was ever done. The only evidence of occurrences of nuclear raw materials is that titaniferous sands occur in several coastal regions and that uranium was once listed as having been produced in Forth Vietnam. Although the geology of Vietnam is not very conducive to the formation and preservation of uranium deposits it is possible that because of the granite terrain and presence of other metalliferous minerals, the Speculative Potential should be stated as in category 2 i.e. from 1,000 to 10,000 tonnes uranium.

  12. International Uranium Resources Evaluation Project (IUREP) national favourability studies: Chile

    1977-08-01

    Chile has an area of 740,760 square kilometers. The capital is Santiago. The country is 4,183 km. long and ranges from 22.5 to about 354 km. in width. Its chief topographic features para]lei each other - the Coastal Range, Andes Mountains and Central Valley. The Coastal Range rises to 2,130 meters in the north, but averages from 610 to 700 meters high generally. The range plunges into the Pacific Ocean far south of Valparaiso and reappears in the southern archipelagic islands. The Andes extend along nearly the entire length of Chile and contain 100 volcanoes. Andean peaks range mostly from 3,000 to 6,700 meters in elevation. In southern Chile the Andes are lower, and contain about a dozen major lakes. The mountains disappear in Chilean Patagonia, but reappear at Cape Horn. The Central Valley lies between the Coastal Range and the Andes, being best defined in the midland region as a 64 to 72 km sloping plain. It is the Chilean heartland with three-quarters of the country's population. Salt basins are found over much of northern Chile in the very arid desert, while the region south of the Gulf of Reloncavi consists of unpopulated islands, fjords, channels and heavily forested mountains. The Strait of Magellan, the Tierra del Fuego archipelago and a flat grassland area make up the extreme southern end of the country. Much of Chile is subject to flash floods, earthquakes, volcanic eruptions, landslides and avalanches. In September 1976 the Comision Chilena de Energia Nuclear (CCEN) was given exclusive rights to negotiate contracts with private companies for the exploration, development and mining of uranium and other radioactive minerals. The new law provides the CCEN with considerable flexibility in the terms of the contracts. Pre-964 owners of uranium deposits may reach agreements with foreign companies to mine the uranium, but since 1964 all uranium has belonged to the state. Uranium produced in the country can only be exported after Chile's needs have been met. The CCEN has invited proposals from international mining companies for the recovery of uranium from copper-bearing waters at the large Chuquicamata mine. As of mid-1977, it was reported that one proposal from all. S. company had been received. It has been estimated that production of 85 tonnes U/year might be realized here. Relatively little interest is shown in uranium by domestic (Chilean) companies because of the fear that the discovery of uranium might lead to nationalization of the properties. In spite of the possibilities mentioned above, there has been relatively little uranium discovered to date in Chile. In view of the relatively small size of these known deposits and until reconnaissance has taken a harder look at these possibilities, it would be prudent to place the potential of Chile in the 1,000-10,000 tonnes range

  13. International Uranium Resources Evaluation Project (IUREP) national favourability studies: Australia

    1977-08-01

    In Australia most exploration for uranium has been conducted by companies and individuals. The geological mapping and airborne radiometric surveying conducted by the BMR is made available to interested persons. Exploration for uranium in Australia can be divided into two periods - 1947 to 1961 and 1966-1977. During the first period the Commonwealth Government introduced measures to encourage uranium exploration including a system of rewards for the discovery of uranium ore. This reward system resulted in extensive activity by prospectors particularly in the known mineral fields. Equipped with a Geiger counter or scintillometer, individuals with little or no experience in prospecting could compete with experienced prospectors and geologists. During this period several relative small uranium deposits were discovered generally by prospectors who found outcropping mineralisation. The second phase of uranium exploration in Australia began in 1966 at which time reserves amounted to only 6,200 tonnes of uranium and by 3 977 reserves had been increased to 289,000 tonnes. Most of the exploration was done by companies with substantial exploration budgets utilising more advanced geological and geophysical techniques. In the field of airborne radiometer the development of multi-channel gamma ray spectrometers with large volume crystal detectors increased the sensitivity of the tool as a uranium detector and resulted in several major discoveries. Expenditure or exploration for uranium increased from 1966 to 1971 but has declines in recent years. After listing the major geological elements of Australia, its uranium production and resources are discussed. During the period 1954-71 the total production of uranium concentrate in Australia amounted to 7,780 tonnes of uranium, and was derived from deposits at Rum Jungle (2,990 tonnes U) and the South Alligator River (610 tonnes U) in the Northern Territory, Mary Kathleen (3,460 tonnes U) in Queensland and Radium Hill (720 tonnes U) in South Australia. The only production at the present time is from the Mary Kathleen deposit which as at 30 June 1977 had produced a further 513 tonnes of uranium since it recommenced operations in 1976. Australia's uranium resources as at 30 June 1977 are estimated as follows (1) Recoverable up to a cost of US$80/kg U (US$30/lb U 3 O 8 ): Reasonably assured resources: 289-000 tonnes U; Estimated additional resources: 44,000 tonnes U. (2) Recoverable at a cost of US$80-130/kg U (US$30-50/lb U 3 O 8 ): Reasonably assured resources : 7,000 tonnes U; Estimated additional resources : 5,000 tonnes U. The reasonably assured resource category is as defined by NEA/IAEA. In expressing Australia's resources the estimated additional resource category is defined as: 'Estimated Additional Resources are confined to uranium which could be recovered within the given cost ranges from those known deposits where there are insufficient data to classify the resources as 'Reasonably Assured', and to extensions of known deposits beyond the limits of 'Reasonably Assured Resources' in those deposits. Quantitative estimates of speculative uranium resources have not been made for Australia

    1977-08-01

    Bolivia has an area of 1,098,580 square kilometers. Its capital is La Paz. The western part of the country is dominated by two ranges of the Andes Mountains, the Cordillera Occidental on the vest flank of the high plateau (Altiplano) and the Cordillera Real (or Oriental) on the east flank. The northern Andes average 5,486 meters in elevation; the southern Andes are not as lofty. The Altiplano is 3,658 to A,267 meters high and 129 km. in average width; it is the largest basin of inland drainage in South America and contains the renowned Lake Titicaca on the Peruvian-Bolivian border. The eastern tropical lowlands or pampas (Oriente) comprise about two-thirds of the country, with rain forest in the northern portion. An intermediate zone of valleys and basins lies between the eastern Andes and Oriente. Bolivia differs from other Andean countries, like Chile, Peru and Ecuador, in having large areas of Preeambrian schists, gneisses, migmatites and granites. These crop out in the eastern part of the country. Parts of these rocks contain banded iron formations (i.e., in the Muttin region) and are probably early Precambrian in age. Little systematic exploration for uranium was undertaken in Bolivia until the late 1960's. In 1967, 1968 and 1969 technical assistance was requested from, and provided by, the IAEA. This work led to evaluation of radioactive anomalies in veins of northeast Bolivia and in sandstones in the extreme southern part of the country. Although no uranium reserves are now credited to Bolivia, the geologic possibilities for several kinds of uranium deposits coupled with the relatively limited work done to date suggest that uranium orebodies will be discovered. It is estimated that the potential resources of Bolivia are in the range of 10,000 to 100,000 tonnes uranium

    Malaysia is a country of 330,000 square kilometers and a population of 11.9 million. The country is divided into two parts 640 kilometers apart. West Malaysia consists of the Malay Peninsula, and East Malaysia of the provinces of Sarawak and Sabah, formerly North Borneo. The country is the world's leading producer of tin and rubber. Geologic descriptions in detail are difficult to find although maps are available. Uranium exploration, chiefly by the Malaysian Geological Survey, has been carried out without discovery of commercial quantities. Based on possible recovery of uranium from deeply weathered granites on the Malay Peninsula, and possible discoveries in East Malaysia, a uranium potential of 1,000 to 10,000 tonnes U (category 2) is assigned.

    1977-08-01

    Turkey has an area of 296 185 sq mi or 767 120 square kilometers. The geology is dominated lay Tertiary and post-Tertiary rocks which are very widespread but extensive outcrops of Mesozoic rocks also occur. Paleozoic rocks, mainly gneisses, mica schists and quartzites occur in the ancient massifs, principally the Istranca massif in Thrace, the Merideres massif in western Anatolia and the Karrshir massif in central Anatolia. Prospecting for uranium began in Turkey in 1953 and the Atomic Energy Raw Materials Division of the Maden Tetkikive Arama Enstitusu (M.T.A.) was founded in 1956. By 1962 a total of 78% of the whole country had been covered by serial radiometric reconnaissance prospecting. Uranium was discovered at Kasar in western Anatolia in 1961 and several hundred tons of reserves estimated two years later. Uranium prospecting was largely recessed from 1963 to 1967. IAEA/UNDP assistance was provided in 1962-63 and 1965 and between 1974 and 1977 in a detailed exploration programme in the Kasar area. In the whole country nearly 600 anomalies and occurrences had been identified by 1963. Several occurrences principally in Western Anatolia had been assigned a small reserve. A recent official estimate places the total national reserve at 3150 tonnes uranium in the less than 30% category of reasonably assured resources. A speculative Potential of between 30,000 and 50,000 tonnes uranium is considered to be reasonable. (author)

    1977-08-01

    Jordanian geology is dominated by the Great Rift Valley System. Most of the country is covered by Cretaceous and Eocene sediments, largely sandstones and limestones. These include phosphorates and bituminous limestones in the Upper Cretaceous, South of the Dead Sea, Mesozoic and Paleozoic rocks overlie exposed granitic Pre Cambrian basement rocks carrying many minor intrusives . Phosphates provide the main mineral export of Jordan. The Natural Resources Authority (Geological Survey and Bureau of Mines) initiated a survey in 1972 of the distribution of uranium on the phosphorite horizon. In 1974 the Survey calculated that the uranium content of the phosphate areas surveyed up to that time was 5 million metric tonnes U 3 O 8 . The average U 3 O 8 content is approximately 0.02% U 3 O 8 . The exploitation of such resources would be as a byproduct of the phosphate industry and dependent on the rate of phosphate production and the capacity of triple super-phosphate plants, none of which exist at the present time. In the southern area in Paleozoic and Pre Cambrian areas there are some hopes of conventional type deposits being found but the potential appears to be small. (author)

    1977-10-01

    Geologically speaking, Lebanon is a young country since the oldest rocks are of Upper Jurassic age. Two volcanic periods are included in the more recent rocks. The country is intersected by numerous faults mainly striking NNE but also including numerous small transverse faults. No prospecting for nuclear raw materials has been recorded and there is no known activity at the present time. Lebanon has no national geological organization to support uranium prospecting. From the geological standpoint, possibilities of occurrences of nuclear minerals in Lebanon are poor and the Speculative Potential is placed in the less than 1000 tonnes uranium category. (author)

  19. International Uranium Resources Evaluation Project (IUREP) national favourability studies: Argentina

    1977-08-01

    Argentina is a predominantly lowland area of 2,789,240 square kilometers. The capital is Buenos Aires. The entire length of Argentina is bordered on the west by the Andes Mountains. Tile Northwest Andes-Piedmont region consists of deep valleys containing salt basins and volcanoes, and is an earthquake zone. Patagonia, in the south, is essentially an arid region of windy plateaus and valleys. The southern Andes are narrower and lower than the northern Andes and in the extreme south contain glaciers and ice fields. The east-central plain (Pampa) of Argentina has dry and humid sectors and contains most of the population. The largest rivers are chiefly in the northeast, many having only seasonal flow. There has been extensive surface and subsurface exploration for uranium in Argentina for over 20 years. Although most of the work has been performed by the CNEA, advisors from the U.S. and from the IAEA have also taken part. Private industry has been involved, but apparently only on a small scale. In the OECD report of 1970, it was stated that 400,000 square kilometers of Argentina appear very favorable for uranium while an additional 900,000 square kilometers offer fair possibilities. Uranium exploration to date suggests that sandstones of Permian and Cretaceous ages exposed in Western Argentina in the Cordillera are very promising for discovery of new deposits. Past CNEA estimates have indicated that there is considerable hope for new discoveries in those areas where reserves are now known. In addition to the known uraniferous provinces which are indeed favorable for further exploration, there are several other large areas that warrant attention. There are, for example, in the Santa Cruz area of about 15,500 square kilometers Cretaceous and Tertiary sediments with favorable facies for uranium deposition. In the Patagonia Cordillera, Jurassic, Cretaceous, and Tertiary sediments are of interest for prospecting, These rocks contain carbonaceous material and have been intruded by acidic rocks. The High Cordiilera, an area of 200,000 square kilometers in northwestern Argentina contains sedimentary, metamorphic, and igneous rocks that could be favorable although the difficult topography is a restrictive influence. The distribution of uranium mineralization in various sediments and other rock types over large areas of Argentina is suggestive of widespread favorability for uranium-ore formation. Inasmuch as uranium reserves plus potential are already estimated at close to 80,000 tons U 3 O 8 , and exploration has not been exhaustively conducted, ultimate resource potential might realistically be expected to fall in the 100,000 to 500,000 ton U 3 O 8 range

  20. International Uranium Resources Evaluation Project (IUREP) national favourability studies: Brazil

    1977-06-01

    Brazil occupies an area of about 8.5 million square kilometers -- almost half of the South American continent. The dominant geographic feature is the Amazon basin. The Amazon River and its more than 200 tributaries drain about 60 percent of the country. The basin is a vast tropical rain forest, whereas the remainder of Brazil is made up predominantly of highlands. The Central Highlands, which extends into the Amazon basin, occupies nearly all of southern Brazil and includes major mountain chains such as the Serra do Mar, Serra da Mantiqueira, and Serra do Espinhago. The Guiana Highlands fringe the northern Amazon basin and extend into Venezuela, Guyana, Surinam, and French Guiana. Lowland areas other than the Amazon basin are found in western Mato Grosso, and along the Atlantic coast from French Guiana to Uruguay. The geology of Brazil is dominated structurally and areally by three major shields composed of crystalline rocks of Archean and Proterozoic age. Collectively they comprise the Brazilian complex which is probably the largest Precambrian outcrop in the world. The complex is made up of gneisses, granites, mica schists, quartzites, dolomites, skarns, diorites, itabirites and gabbros, many of which are deeply metamorphosed. Faults, quartz veins, and dikes are common. Recurrent granitization has occurred from the Precambrian to Late Tertiary. The area of Brazil is large and its geology is favorable, in places, for every known type of uranium deposit. This is not reflected in the amount of 'known' and 'inferred' reserves -- slightly more than 21,000 tons. Rather, it is an indication of the small amount of exploration done, taking into account the large area to be covered. The speculative potential can only be guessed. It is guessed to be 500,000 tons

    1977-12-01

    Taiwan is an island of 36,000 sq km located 160 km east of mainland China. Geologically, the oldest rocks are Tertiary, and the only igneous rocks on the island are Quaternary andesites and basalts. Copper, gold, and silver are the only known metallic minerals produced. Uranium occurrences and exploration efforts are unknown. The potential uranium resource of Taiwan is considered a category 1 resource. (author)

  2. International Uranium Resources Evaluation Project (IUREP) national favourability studies: Honduras

    1977-08-01

    In 1953, the U.S. Atomic Energy Commission, on invitation of the government of Honduras, conducted uranium reconnaissance in parts of the country. The survey consisted of scintillometric examination of all formations, veins, dikes, sills and contacts along more than 1,500 km of road. Additionally, 17 mines and prospects were examined, but in no location were uranium occurrences found. The largest and most consistently radioactive deposit noted was a body of volcanic ash at Santa Rosa de Copan, a sample of which assayed 15 ppm U 3 O 8 . A uranium prospect has been described from the Yatnala area in northwest Honduras. Uraninite and oxidation products occur in association with copper and mercury minerals in veinlets as well as disseminations in a Lower Cretaceous limestone conglomerate, the llama Formation. The llama Formation is the conglomeratic facies of the Atima (limestone) Formation, both of which are in the Yojoa Group. At the time of the U. N. development program survey in May, 1970, no uranium deposits were known in Honduras. Information is not available on current exploration in Honduras. The state owns most mineral deposits but may grant rights for exploration and exploitation of the subsoil. Mineral and surface titles are separate. Deposits of uranium and its salts, thorium and similar atomic energy substances are reserved to the state. Foreign citizens and companies, with some exceptions, may acquire mineral rights. Several groups of sediments might be of interest for uranium exploration. The Todos Santos redbeds and the El Plan Formation are both shallow marine and hence may contain marginal marine facies favorable for uranium. In the southern and central Cordillera, the Valle de Angeles sediments, particularly the sandstones, may be of interest. The contacts between Permian granites and schists (Paleozoic) may also warrant attention. Lacking further information on which to base a more optimistic outlook, it is estimated that the uranium potential of Honduras may be on the order of 1,000 to 10,000 tonnes

    Niue is described as a coral island containing 259 square kilometers, located between Tonga and the Southern Cook Islands in the Central Pacific.

    closed depressions and (open) valleys This was the impact of two factors. 1. Impact of natural forest evolution on soil erosivity. Fagus arrived in the area, jostled Tilia in the Subboreal and extended in the Subatlantic. The understory and humus forms changed, the erosivity of the surface increased and the consequence was accelerating soil erosion. Stable mardels changed in sediment traps, river valleys got constipated with colluvic/alluvic sediments. 2. Anthropogenic deforestation and extension of agriculture since Roman Time. Conclusions. 1. In a lot of studies, deforestation was considered as the responsible factor for soil erosion. 2. Impact of natural forest evolution (the appearance of Fagus) was not recognized 3. The impact of the Little Ice Age on Subatlantic soil erosion was not recognized 4. Three factors controlled Subatlantic soil erosion and mardel and valley deposition - The (natural) jostle of mixed oak forest by beach forest promoted soil erosivity and erosion - The (anthropogenic) deforestation and expansion of agriculture promoted soil erosion - The temporally move from pasture to arable land during the Little Ice Age promoted soil erosivity References. - Barth B (1996) Mardellen im Lotharingischen Gipskeuper.

  5. Towards prospective life cycle sustainability analysis: exploring complementarities between social and environmental life cycle assessments for the case of Luxembourg's energy system

    Rugani, B.; Benetto, E.; Igos, E.; Quinti, G.; Declich, A.; Feudo, F.

    2014-01-01

    Sustainability typically relies on the durable interaction between humans and the environment. Historically, modelling tools such as environmental-life cycle assessment (E-LCA) have been developed to address the mitigation of environmental impacts generated by human activities. More recently, social-life cycle assessment (S-LCA) methods have been proposed to investigate the social sustainability sphere, looking at the life cycle effects generated by positive or negative pressures on social endpoints (i.e. well-being of stakeholders). Despite this promising added value, however, S-LCA methods still show limitations and challenges to be faced, e.g. regarding the lack of high quality datasets and the implementation of consensual social impact assessment indicators. This paper discusses on the complementarity between S-LCA and E-LCA towards the definition of prospective life cycle sustainability analysis (LCSA) approaches. To this aim, a case study is presented comparing (i) E-LCA results of business-as-usual (BAU) scenarios of energy supply and demand technology changes in Luxembourg, up to 2025, based on economic equilibrium modeling and hybrid life cycle inventories, with (ii) a monetary-based input-output estimation of the related changes in the societal sphere. The results show that environmental and social issues do not follow the same impact trends. While E-LCA outputs highlight contrasting patterns, they do generally underlie a relatively low decrease in the aggregated environmental burdens curve (around 20% of decrease over the single-score impact trend over time). In contrast, social hotspots (identified in S-LCA by specific risk indicators of human rights, worker treatment, poverty, etc.) are typically increasing over time according to the growth of the final energy demand. Overall, the case study allowed identifying possible synergies and tradeoffs related to the impact of projected energy demands in Luxembourg. Despite the studied approach does not fully

  6. Uranium prospecting and geological favour ability in Uruguay

    Goso, H.

    1981-01-01

    Uranium prospecting carried out in Uruguay since 1976 is described. On the basis of literature available and of an analysis of the large structural units pertinent to Uruguay's geology, the prospecting performed in general in the northeast of the country, and in particular in the districts of Cerro Largo and Las Canas, is described. Some information is presented on uranium favour ability in Uruguay related to sedimentary formations: Devonian (Cerrezuelo Formation) and Gondwana (San Gregorio and Tres Islas Formations), and to the Crystalline formations of the centre and Southwest (1700-2000 m.y.) and of the east and southeast (500-700 m.y.)

  7. Archaeometrical analyses demonstrates that humans excavated clay from mardels on the Luxembourger Gutland plateau to produce ceramics.

    Vanmourik, Jan; Braekmans, Dennis

    2017-04-01

    Mardels, small closed depressions, are distinctive landforms on the Luxembourger Gutland plateau. In the present landscape most mardels are shallow fens, filled with colluvial sediments. Slotboom (1963) investigated 108 mardels in the Luxembourger Gutland and ascribed the mardels in the Luxembourger Keuper marl formations to subsurface solution of gypsum inclusions, followed by collapse and subsidence of the overlying beds. The colluvial deposits in the mardels were palynologically dated as Post Roman. Schmalen (2001) published an actualized inventory of mardels in the Gutland. This inventory includes also mardels on the Lias marls, a formation without gypsum inclusions. Etienne et al. (2011) considered beside natural processes also anthropogenic factors as explanation for CD's in the Lorraine landscape. The sediments in the majority of the CD's were palynologically dated as Post Roman. Combined with the open character of the local vegetation this suggest that the majority of the mardels are probably abandoned Roman quarries. Slotboom and van Mourik (2015) showed that the fillings of the mardels on the Lias marls are Post-Roman, just as on the Keuper marls. To answer the question "are mardels natural subsidence basins or abandoned quarries" we need additional information from the soil archives. Firstly we must identify the process, responsible for the deposition of clay in the mardels. The majority of the mardels in the Gutland occur in clusters in deciduous forests. Earthworm activity in the forest soils promote lateral clay leaching and soil erosion and mardels function as sediment traps. Due to this process clay with the best properties for the production of ceramics occurred in mardels. This process was active during the whole Holocene. It is striking that we did not find Pre-Roman but only Post-Roman mardel fillings. Secondly we need information about the practice of clay, excavated from mardels. If mardels are really abandoned quarries, the excavated

  8. Will hydrogen be competitive in Europe without tax favours?

    Hansen, Anders Chr.

    2010-01-01

    Hydrogen is one of the alternative transport fuels expected to replace conventional oil based fuels. The paper finds that it is possible for non-fossil-based hydrogen to become the lowest cost fuel without favourable tax treatment. The order of per kilometre cost depends on performance in hydrogen production, the international oil price, and fuel taxes. At low oil prices, the highest per kilometre costs were found for non-fossil power-based hydrogen, the second highest for natural gas-based hydrogen, and the lowest for conventional fuels. At high oil prices, this ranking is reversed and non-fossil power-based hydrogen becomes the most cost competitive fuel. General fuel taxes lower the threshold at which the international oil price reverses this competitiveness order. The highest fuel tax rates applied in Europe lowers this threshold oil price considerably, whereas the lowest fuel taxes may be insufficient to make hydrogen competitive without tax favours. Alternative adjustments of the EU minimum fuel tax rates with a view to energy efficiency and CO 2 -emissions are discussed.

    Correlative species distribution models are based on the observed relationship between species' occurrence and macroclimate or other environmental variables. In climates predicted less favourable populations are expected to decline, and in favourable climates they are expected to persist. However, little comparative empirical support exists for a relationship between predicted climate suitability and population performance. We found that the performance of 93 populations of 34 plant species worldwide - as measured by in situ population growth rate, its temporal variation and extinction risk - was not correlated with climate suitability. However, correlations of demographic processes underpinning population performance with climate suitability indicated both resistance and vulnerability pathways of population responses to climate: in less suitable climates, plants experienced greater retrogression (resistance pathway) and greater variability in some demographic rates (vulnerability pathway). While a range of demographic strategies occur within species' climatic niches, demographic strategies are more constrained in climates predicted to be less suitable. © 2017 The Authors.

    Search for baryon resonances with the 5/2 isotopic spin was carried out. Experimental data was obtained in π - p interactions on the hydrogen bubble chamber at 4.5 GeV/c. The investigated channels of the reaction were nπ + π + π - π - , pπ + π - π - π 0 and pπ + π - π - . The effective mass distributions of the products of the reaction were presented. The results of the paper pointed out that 5/2 isobars could be produced in the first channel which corresponded the Feynman diagram with the Δ - (1232) exchange. Particle production of the Δ ++ (1232) isobar in the second and third channels was an inderect evidence in favour

    2011-07-01

    The study aimed to review the results of endovascular aneurysm repair (EVAR) using a novel sac-anchoring endoprosthesis in patients with favourable and adverse anatomy. This is a prospective, multicentre, clinical trial. The Nellix endoprosthesis consists of dual, balloon-expandable endoframes, surrounded by polymer-filled endobags, which obliterate the aneurysm sac and maintain endograft position. The study reviewed worldwide clinical experience and Core Lab evaluation of computed tomography (CT) scans. From 2008 to 2010, 34 patients (age 71 ± 8 years, abdominal aortic aneurysm (AAA) diameter 5.8 ± 0.8 cm) were treated at four clinical sites. Seventeen patients (50%) met the inclusion criteria for Food and Drug Administration (FDA)-approved endografts (favourable anatomy); 17 (50%) had one or more adverse anatomic feature: neck length 60° (9%) and iliac diameter >23 mm (38%). Device deployment was successful in all patients; iliac aneurysm treatment preserved hypogastric patency. Perioperative mortality was 1/34 (2.9%); one patient died at 10 months of congestive heart failure (CHF); one patient had a secondary procedure at 15 months. During 15 ± 6 months follow-up, there were no differences in outcome between favourable and adverse anatomy patients. Follow-up CT extending up to 2 years revealed no change in aneurysm size or endograft position and no new endoleaks. Favourable and adverse anatomy patients can be successfully treated using the Nellix sac-anchoring endoprosthesis. Early results are promising but longer-term studies are needed.

    2015-11-05

    The question whether euthanasia should be legalised has led to substantial public debate in France. The objective of this study in a sample of French physicians was to establish the potential determinants of a favourable opinion about euthanasia in general and when faced with a specific situation as embodied in the Humbert affair. The study was a cross-sectional survey investigating two different samples of medical doctors: (1) those specialised in palliative care and affiliated to the French Society for Patient Accompaniment and Palliative Care; (2) medical interns (medical doctors in training course) in a French medical university (Marseille). A questionnaire was sent (email) to each voluntary participant including sociodemographics, professional status, mention of believing in God, and opinion about euthanasia (the question was designed to assess the general opinion about euthanasia and the opinion about a specific case, the Vincent Humbert' case (a man who was rendered quadriplegic, blind, and mute after an accident and has requested euthanasia). A total of 413 physicians participated in the research (participation rate: 48.5%). Less than half of the population were favourable to euthanasia in general and almost two-thirds of the population were favourable to Vincent Humbert's request for euthanasia. Based on the multivariate analysis, individuals believing in God and being a medical intern were significant independent factors linked to having a favourable opinion about euthanasia in general and about the Vincent Humbert's request. There is still no study in France on the development of opinion about euthanasia and its impact. The issue goes beyond the strictly professional sphere and involves broader socio-political stakes. These stakes do not necessarily take into account medical practices and experiences or the desires of end-of-life patients. The professional upheaval that the future French legal framework will doubtlessly trigger will require further

  15. Employee participation in the private sector in Malaysia: The Applicability of Favourable Conjunctures Model

    Balakrishnan Parasuraman

    2009-12-01

    Full Text Available EP is one crucial aspect of the employment relationship in both private and public organisations in many countries. In 2001, Poole, Lansbury and Wiles developed a model for comparative EP, which they named the Favourable Conjunctures Model. So far, this model has only been applied in developed countries such as the United States of America, United Kingdom, Australia and Europe. There it was applied in order to examine worker participation from the national perspective. No extensive study has been conducted using this model to explain worker participation practices at the company level. In parallel with this aspect, this model also has never been used to explain the nature of EP in the Asian developing countries. This current research will use the Favourable Conjunctures Model to examine the nature of EP in private enterprises based on empirical study carried out in Malaysia. The argument of this paper is that the Favourable Conjunctures Model of Industrial Democracy (Poole et al. 2001 is inadequate to elucidate the characteristics of EP in Malaysia. Based on empirical findings from three private companies in Malaysia, the paper argues that there are many contextual factors that influence the nature of EP in Malaysian private companies that are not taken into account by the model. They are:multi-ethnic (cultural influences, the repressive role of state in the Malaysian industrial relations, the New Economic Policy and industrialisation plan, Islamic working ethics, the influence of a British colonial history, lack of training among non-managerial employees in EP, the impact of foreign direct investment on industrial relations, to identify a few. Based on this study, it is proposed that the present Favourable Conjunctures Model of Industrial Democracy (Poole et al. 2001 be modified based on the contextual factors discussed above. The paper concludes that the western model of EP could not be directly applied in Malaysia without some adjustment of

  18. Do Refuge Plants Favour Natural Pest Control in Maize Crops?

    Quispe, Reinaldo; Mazón, Marina; Rodríguez-Berrío, Alexander

    2017-01-01

    The use of non-crop plants to provide the resources that herbivorous crop pests’ natural enemies need is being increasingly incorporated into integrated pest management programs. We evaluated insect functional groups found on three refuges consisting of five different plant species each, planted next to a maize crop in Lima, Peru, to investigate which refuge favoured natural control of herbivores considered as pests of maize in Peru, and which refuge plant traits were more attractive to those desirable enemies. Insects occurring in all the plants, including the maize crop itself, were sampled weekly during the crop growing cycle, from February to June 2011. All individuals collected were identified and classified into three functional groups: herbivores, parasitoids, and predators. Refuges were compared based on their effectiveness in enhancing the populations of predator and parasitoid insects of the crop enemies. Refuges A and B were the most effective, showing the highest richness and abundance of both predators and parasitoids, including several insect species that are reported to attack the main insect pests of maize (Spodoptera frugiperda and Rhopalosiphum maidis), as well as other species that serve as alternative hosts of these natural enemies.

  20. A new perspective on catchment storage gained from a nested catchment experiment in Luxembourg (Europe)

    Pfister, Laurent; Klaus, Julian; Hissler, Christophe; François Iffly, Jean; Gourdol, Laurent; Martinez-Carreras, Nuria; McDonnell, Jeffrey J.

    2014-05-01

    Recent hydrological process research focussed on how much water a catchment can store and how these catchments store and release water. Storage can be a valuable metric for catchment description, inter-comparison, and classification. Further storage controls catchment mixing, non-linearities in rainfall-runoff transformation and eco-hydrological processes. Various methods exist to determine catchment storage (e.g. natural tracer, soil moisture and groundwater data, hydrological models). Today it remains unclear what parts of the catchment storage are measured with the different models. Here we present a new hydrometric approach to answer the question how much water a catchment can store. We tested our approach in a dense hydro-climatological monitoring network that encompasses 16 recording streamgauges and 21 pluviographs in the Alzette River basin in Luxembourg (Europe). Catchment scales are ranging from 0.47 to 285 km2 and they have clean- and mixed combinations of distinct geologies ranging from schists to marls, sandstone, dolomite and limestone. Previous investigations in the area of interest have shown that geology largely controls winter runoff coefficients. Here, we focus at how catchment geology is ultimately affecting catchment storage. We used the approach of Sayama et al. (2011) to compute catchment dynamic storage changes for each winter season over the period 2002-2012 (based on precipitation as input; discharge and evapotranspiration as output). We determined dynamic storage changes for each winter semester (October to March) in all 16 catchments over the period 2002-2012. At the beginning of each hydrological winter season, all catchments showed similar trends in storage change. A few weeks into the winter season, catchments with lowest permeability (e.g. marls) started to plateau. The highest storage values were reached several months later in the season in catchments dominated by permeable substrate (e.g. sandstone). For most catchments, we found

  2. Surface heat flow and lithosphere thermal structure of the larger Luxembourg area as a basis for the evaluation of its geothermal potential

    Schintgen, Tom; Förster, Andrea

    2014-05-01

    The evaluation of the geothermal potential and the type of geothermal use necessitates knowledge of the subsurface temperature distribution in combination with hydraulic properties (e.g. porosity, permeability and hydraulic conductivity). In the larger Luxembourg area, only a few subsurface temperature data are available restricted to shallow depth. This paucity in data required to assess the thermal regime to drillable depths by modeling. The thermal model was constrained by surface heat flow and the lithosphere-asthenosphere boundary (LAB) characterized by the 1300° C isotherm. A surface heat-flow value of 75 ± 7 (2σ) mW m-2 was determined in central Luxembourg, which corroborates most values known from adjacent areas. The conceptual geological model for thermal modeling has a high resolution in the upper 15 km due to a wealth of geological data, while refraction seismic data and xenoliths provide petrological constraints for the lower part of the model down to the crust/mantle boundary. Thermal rock properties assigned to geological units are based on a large set of laboratory data, complemented by some literature data for the lower parts of the crust. The thermal structure is investigated by calculating 2-D steady-state thermal models along three crustal cross sections developed for the study area assuming a purely conductive lithosphere. The location of the LAB at 100 km depth, as typical for the Ardennes, provides the best fit with the measured surface heat flow of about 75 mW m-2. This LAB model provides temperatures at 5 km of 115-118° C on average and of about 600° C at the Moho. The resulting mantle heat flow in this model is 39-40 mW m-2. A reduced lithosphere thickness of 50 km as typical for the Eifel area to the east results in an increase of surface heat flow to 97 mW m-2 and of the mantle heat flow to 65 mW m-2, respectively. If heating from the Eifel plume had reached the surface yet, temperatures at 5 km would be about 20° C higher (and

  12. Pharmacological manipulation of serotonin receptors during brain embryogenesis favours stress resiliency in female rats

    Gianluca Lavanco

    2018-02-01

    Full Text Available Manipulations of the serotonin transmission during early development induce long-lasting changes in the serotonergic circuitry throughout the brain. However, little is known on the developmental consequences in the female progeny. Therefore, this study aimed at exploring the behavioural effects of pre- and postnatal stimulation of the serotonergic system by 5-methoxytryptamine in adolescent female rats on behavioural reactivity and anxiety- like phenotype. Our results show that perinatal 5- methoxythyptamine decreased total distance travelled and rearing frequency in the novel enviroment, and increased the preference for the centre of the arena in the open field test. Moreover, perinatal 5-methoxytryptamine increased the percentages of entries and time spent on the open arms of the elevated plus maze, with respect to perinatally vehicle-exposed rats. Thus, perinatal stimulation of serotonin receptors does not impair the functional response to the emotional challenges in female rats, favouring the occurrence of a stress-resilient phenotype.

  13. The voice of Holland: Dutch public and patient's opinion favours single-port laparoscopy.

    Fransen, Sofie Af; Broeders, Epm; Stassen, Lps; Bouvy, Nd

    2014-07-01

    Single-port laparoscopy is prospected as the future of minimal invasive surgery. It is hypothesised to cause less post operative pain, with a shorter hospitalisation period and improved cosmetic results. Population- and patient-based opinion is important for the adaptation of new techniques. This study aimed to assess the opinion and perception of a healthy population and a patient population on single-port laparoscopy compared with conventional laparoscopy. An anonymous 33-item questionnaire, describing conventional and single-port laparoscopy, was given to 101 patients and 104 healthy volunteers. The survey participants (median age 44 years; range 17-82 years) were asked questions about their personal situation and their expectations and perceptions of the two different surgical techniques; conventional multi-port laparoscopy and single-port laparoscopy. A total of 72% of the participants had never heard of single-port laparoscopy before. The most important concern in both groups was the risk of surgical complications. When complication risks remain similar, 80% prefers single-port laparoscopy to conventional laparoscopy. When the risk of complications increases from 1% to 10%, 43% of all participants prefer single-port laparoscopy. A total of 70% of the participants are prepared to receive treatment in another hospital if single-port surgery is not performed in their hometown hospital. The preference for single-port approach was higher in the female population. Although cure and safety remain the main concerns, the population and patients group have a favourable perception of single-port surgery. The impact of public opinion and patient perception towards innovative techniques is undeniable. If the safety of the two different procedures is similar, this study shows a positive attitude of both participant groups in favour of single-port laparoscopy. However, solid scientific proof for the safety and feasibility of this new surgical technique needs to be obtained

    2016-06-01

    Growing evidence suggests that sleep is important for procedural learning, but few studies have investigated the effect of sleep on the temporal aspects of motor skill learning. We assessed the effect of a 90-min day-time nap on learning a motor timing task, using 2 adaptations of a serial interception sequence learning (SISL) task. Forty-two right-handed participants performed the task before and after a 90-min period of sleep or wake. Electroencephalography (EEG) was recorded throughout. The motor task consisted of a sequential spatial pattern and was performed according to 2 different timing conditions, that is, either following a sequential or a random temporal pattern. The increase in accuracy was compared between groups using a mixed linear regression model. Within the sleep group, performance improvement was modeled based on sleep characteristics, including spindle- and slow-wave density. The sleep group, but not the wake group, showed improvement in the random temporal, but especially and significantly more strongly in the sequential temporal condition. None of the sleep characteristics predicted improvement on either general of the timing conditions. In conclusion, a daytime nap improves performance on a timing task. We show that performance on the task with a sequential timing sequence benefits more from sleep than motor timing. More important, the temporal sequence did not benefit initial learning, because differences arose only after an offline period and specifically when this period contained sleep. Sleep appears to aid in the extraction of regularities for optimal subsequent performance. (PsycINFO Database Record (c) 2016 APA, all rights reserved).

  15. Energy efficiency of new school buildings and office buildings in Luxembourg based on consumption data and simulations; Energieeffizienz neuer Schul- und Buerogebaeude in Luxemburg basierend auf Verbrauchsdaten und Simulationen

    Thewes, Andreas

    2011-07-01

    In Luxemburg, energy consumption in the building and housing sector has been significantly increasing over the last years. From 1990 to 2005, the fraction of the tertiary sector (including private and public households), compared to the entire national energy consumption, increased from only 20% to 31% [ENEL, 2008]. An assessment of the energy saving potential of buildings requires a comprehensive data basis with real consumption figures that are not yet available. Assessments on energy saving measures conducted so far are only based on rough estimates. One focus of this study was to create a priori a detailed energy consumption database for new ''School and Administrative Buildings'' for Luxembourg. These are both groups pursuant to the EU Directive [EU, 2010] and cover a major part of the building and housing sector in Luxembourg besides residential buildings. Based on the samples collected, it was able to expand the figures to the entire country using mathematical methods and the medium heat and electricity consumption of these two types of buildings. After collecting some details about each object, it was able to analyze the influence of different parameters, such as building age, size, type, glass fraction etc., on energy consumption using multivariate statistical methods. A posteriori, the results from the database were verified using parameter studies to existing objects and one object still under construction. Based on this, important key parameters relevant for both energy savings and thermal comfort could be found. This knowledge are necessary to understand energy flows within buildings better and, based on this, to be able meeting the nearly zero energy buildings requirements as set out by the EU Directive in the years to come. In particular, this study focused on the negative effects of growing window areas on the energy consumptions and discussed them thoroughly. Also, we tested and/or provided calculational evidence of further

    Full Text Available

    Abstract
    Any hypothesis aiming to explain the social organisation of Eurasian badgers Meles meles has to consider its wide inter-population variability. We used radiotracking techniques to investigate the spatial organisation and the pattern of space-use by badger in Luxembourg, where badger density can be considered moderate compared to most of Europe.
    Eight badgers belonging to five social groups were caught and radio-collared. The size of individual home ranges, as assesses by 100% minimum convex polygons in spring-summer 2002 and 2003, varied from 42.5 ha to 171.8 ha. Core areas corresponded to the 50-70% kernel isopleths and covered an average of 10.1% of individual home ranges. The home ranges of badgers caught at the same sett overlapped largely (average 83.3%, whilst the overlap between neighbouring ranges did not exceed 13.8%. Altogether six boundary latrines were found at the intersection of group ranges. Overall, the spatial system of the Luxembourg badgers is quite flexible, with the boundaries of some group ranges remaining constant over the years, while others may expand or contract.

    A case of favourable outcome of the treatment of extremely severe acute poisoning after prolonged exposure to lethal doses of methanol is reported. The complex treatment included urgent and effective elimination of the poison (multiple gastric lavage, hemodialysis), antidote therapy (administration of ethanol), correction of decompensated metabolic acidosis (alkali therapy and infusion therapy with reamberin). These measures had beneficial effect on the clinical course of poisoning and ensured its favourable outcome.

    2015-06-01

    Full Text Available The article deals with the dynastic policies of Charles IV. and his ideas about the arrangement of government in the Crown of Bohemia. It refers to so-called emperor’s testaments where the emperor describes in detail the succesion of the male members of the Luxembourg line and denotes their rank in rule. The pillar of the whole structure was the King of Bohemia, the absolute sovereign over all of the lands of the Crown of Bohemia. The remaining Luxembourgs were to hold their lands as a royal tenure. In this spirit, Charles IV. created a whole new duchy of Görlitz for his son John.

  3. Application of XAD-2 resin-based passive samplers and SPME–GC–MS/MS analysis for the monitoring of spatial and temporal variations of atmospheric pesticides in Luxembourg

    Schummer, Claude; Tuduri, Ludovic; Briand, Olivier; Appenzeller, Brice M.; Millet, Maurice

    2012-01-01

    Passive air sampling has been shown to be a very interesting alternative to high-volume sampling by overcoming its disadvantages (size, weight, expensiveness). However, to date, only limited data is available about passive air sampling of current-use pesticides. In order to test if passive samplers allow monitoring of spatial and temporal variations of atmospheric pesticide concentrations, five XAD-2-resin based passive air samplers were deployed at five locations in Luxembourg. Samplers were analyzed using accelerated solvent extraction coupled to solid-phase microextraction and gas chromatography with tandem mass spectrometry. Collected data was used to study the spatial and temporal variations of the concentrations of the compounds. Twenty two pesticides were detected between March and October, while no pesticides were detected from November to February. Highest concentrations were measured on the rural sites, suggesting that the used XAD-2 resin-based passive samplers allow the simultaneous monitoring of multiple current-use pesticides and identifying spatial and temporal variations. - Highlights: ► XAD-2 passive sampling of current-used pesticides. ► Coupling of ASE and SPME–GC–MS/MS for the analysis of pesticides in XAD-2 passive sampling. ► XAD-2 passive samplers suitable for current-used pesticides atmospheric sampling. ► XAD-2 passive samplers suitable for spatial and temporal atmospheric concentrations variations. - XAD-2 passive sampling of current-use pesticides in the atmosphere.

  4. Current role and future developments of radiotherapy in early-stage favourable Hodgkin's lymphoma

    Eich, H.T.; Mueller, R.P.

    2007-01-01

    The radiosensibility of Hodgkin's lymphoma (HL) is well established since 1902, when Pusey was one of the first to publish about radiotherapeutical treatment of a HL. In the early years, radiotherapy was the only curative treatment for this systemic disease, but the reports of Kaplan and Rosenberg and Peters in the fifties and seventies showed that irradiation of involved lymph node regions only resulted in high local and distant recurrences. The introduction of linear accelerator based high dose extended field (EF)-radiotherapy by Kaplan in Stanford was a milestone in the evolution of definitive curative radiotherapy strategies. The application of the mantle field for supradiaphragmatic and the inverted Y (with or without including the spleen or splenic pedicle) for infradiaphragmatic disease resulted in a dramatic improvement of survival rates in the early stages I and II (Ann Arbor) from 25-30% in the sixties to 65-80% in the eighties. Kaplan reported about a close relationship between radiation dose and cure rates in the case of definitive radiotherapy. A dose of at least 40 Gy resulted in local recurrences below 5% and is today the standard dose for radiotherapy only outside protocols. Despite complete remission rates after radiotherapy of 90-100%, the overall recurrence rate (including in-field, marginal and distant relapses) was between 20 and 30%. Analysis of the relapses revealed some stage migrating risk factors: large mediastinal mass, extra nodal involvement, number of involved lymph node areas (≥ 3) and high ESR. The possibility of more accurate staging by using new imaging techniques like ultrasonography, CT and MRI as well as PET in the recent years resulted e.g. in the definition of early-favourable, early-unfavourable (intermediate) and high risk stages and more specific, risk adapted treatment strategies. The objective of this article is to show recent achievements and developments in the management of early-stage favourable HL exemplified by

  5. Blood pressure targets in type 2 diabetes. Evidence against or in favour of an aggressive approach.

    Mancia, Giuseppe; Grassi, Guido

    2018-03-01

    When associated with high blood pressure, type 2 diabetes mellitus is characterised by a high risk of adverse cardiovascular (CV) and renal outcomes. However, both can be effectively reduced by antihypertensive treatment. Current guidelines on the treatment of hypertension emphasize the need to effectively treat high blood pressure in diabetic individuals, but their recommendations differ in terms of the optimal target blood pressure value to aim for in order to maximise CV and renal protection. In some guidelines the recommended target blood pressure values are blood pressure values close or even less than 130/80 mmHg are recommended. This paper will discuss the evidence for and against a conservative or more aggressive blood pressure target for treated diabetic hypertensive individuals based on the evidence provided by randomised trials, trial meta-analyses and large observational studies. Based on the available evidence, it appears that blood pressure targets will probably have to be lower than <140/90 mmHg, and that values approaching 130/80 mmHg should be recommended. However, evidence in favour of even lower systolic values, i.e. <130 mmHg, is limited and is definitively against a reduction to <120 mmHg.

  6. Calculation of climate factors as an additional criteria to determine agriculturally less favoured areas

    2016-04-01

    Full Text Available Climate factors that are proposed to determine agriculturally less favoured areas (LFA in Slovenia were analyzed for the period 1981–2010. Following the instructions of European Commission prepared by Joint Research Centre (JRC 30-years averages of low air temperatures criteria (the vegetation period duration and sums of effective air temperatures and aridity criteria (aridity index AI have to be calculated. Calculations were additionally done using Slovenian Environment Agency (ARSO method, which is slightly different when determining temperature thresholds. Only hilly areas are below the LFA low air temperatures threshold with the lowest located meteorological station in Rateče. According to aridity criteria no area in Slovenia is below the threshold, so meteorological water balance was also examined. Average water balance in the period 1981–2010 was in most of locations lower than in the period 1971–2000. Climate change impacts are already expressed as trend presence in time series of studied variables, so it is recommended to calculate trends and take them into account or to perform regular iterations of calculations.

  7. Living with strangers: direct benefits favour non-kin cooperation in a communally nesting bird.

    Riehl, Christina

    2011-06-07

    The greater ani (Crotophaga major), a Neotropical cuckoo, exhibits an unusual breeding system in which several socially monogamous pairs lay eggs in a single nest and contribute care to the communal clutch. Cooperative nesting is costly-females compete for reproduction by ejecting each other's eggs-but the potential direct or indirect fitness benefits that might accrue to group members have not been identified. In this study, I used molecular genotyping to quantify patterns of genetic relatedness and individual reproductive success within social groups in a single colour-banded population. Microsatellite analysis of 122 individuals in 49 groups revealed that group members are not genetic relatives. Group size was strongly correlated with individual reproductive success: solitary pairs were extremely rare and never successful, and nests attended by two pairs were significantly more likely to be depredated than were nests attended by three pairs. Egg loss, a consequence of reproductive competition, was greater in large groups and disproportionately affected females that initiated laying. However, early-laying females compensated for egg losses by laying larger clutches, and female group members switched positions in the laying order across nesting attempts. The greater ani, therefore, appears to be one of the few species in which cooperative breeding among unrelated individuals is favoured by direct, shared benefits that outweigh the substantial costs of reproductive competition.

    Paraneoplastic pemphigus (PNP) is an autoimmune blistering disorder that occurs in association with an underlying neoplasm. Inflammatory myofibroblastic tumour (IMT) is a rare low-grade sarcoma of fibroblasts and myofibroblasts associated with inflammatory cells, most commonly occurring in the lung. In this study, a case of PNP associated with IMT of the mediastinum is reported. The patient had a favourable outcome following surgical resection and treatment with a systemic steroid, azathioprine, and i.v. immunoglobulin. The occurrence of PNP with sarcomas, specifically IMT, is noteworthy although it is not well studied in the existing literature. © 2014 The Australasian College of Dermatologists.

  13. Anisotropy of favoured alpha transitions producing even-even deformed nuclei

    Tavares, O.A.P.

    1997-05-01

    The anisotropy in favoured alpha transitions which produce even-even deformed nuclei is discussed. A simple, Gamow's-like model which takes into account the quadrupole deformation of the product nucleus has been formulated to calculate the alpha decay half-life. It is assumed that before tunneling into a purely Coulomb potential barrier the two-body system oscillated isotropically, thus giving rise to an equivalent, average preferential polar direction θ 0 (referred to the symmetry axis of the ellipsoidal shape of the product nucleus) for alpha emission in favoured alpha transitions of even-even nuclei.

    2014-12-01

    Full Text Available The aim of our study is to present the administrative system in some European Union member states. The systemic approach offers us the possibility to achieve a comprehensive overview of the scope and content of public administration. In terms of systemic evaluation, public administration is seen as a social entity specific to certain period of development, characterized by a mode of action, structure and logic. Starting from the systemic approach we will highlight how member states' constitutional regulations tailored the European administrative systems. Public administration, as a system, is understood as an evolutionary process, with objects, attributes and relationships that combine and allow proper operation. Also, public administration system approach provides the basis for a consistent and rigorous approach to an ideal model of government that summarizes all the advantages - goals for any administration, namely: nationality, effectiveness, optimum citizens serving etc.

  16. Investigation of an excess of Salmonella enteritidis phage type 14b and MLVA type 4-7-3-13-10-2-2 in Luxembourg, Belgium and Germany during 2010.

    Mossong, J; Ragimbeau, C; Schuh, J; Weicherding, P; Peetso, R; Wildemauwe, C; Imberechts, H; Rabsch, W; Bertrand, S

    2012-01-01

    We investigated an increase of human cases of Salmonella Enteritidis occurring from August until November 2010 in Belgium, Luxembourg and Germany involving an estimated three hundred laboratory confirmed cases. Molecular typing indicated that the increase in Luxembourg and Belgium was due a particular strain having phage type 14b, MLVA pattern 4-7-3-13-10-2-2 and fully susceptible to the Enternet panel of antibiotics. MLVA and phage typing were found to have similar discriminatory power on a collection of 40 Belgian and Luxembourg strains isolated during 2010. Epidemiological investigations in Luxembourg suggested eggs as a possible source for some cases, although supermarket eggs tested were negative. No other EU countries observed a substantial increase of cases, although three smaller outbreaks in Germany were also due to a strain with the same phage type and MLVA pattern. In 2010 the EU directive banning battery cages came into force in Germany followed by a dioxin food scare incident. Given that the EU Laying Hens Directive will come into force across all Member States in 2012, a closer monitoring of Salmonella contamination of imported eggs at retail and wholesale level is recommended.

  18. Reconstructed Ancestral Enzymes Impose a Fitness Cost upon Modern Bacteria Despite Exhibiting Favourable Biochemical Properties.

    Hobbs, Joanne K; Prentice, Erica J; Groussin, Mathieu; Arcus, Vickery L

    2015-10-01

    Ancestral sequence reconstruction has been widely used to study historical enzyme evolution, both from biochemical and cellular perspectives. Two properties of reconstructed ancestral proteins/enzymes are commonly reported--high thermostability and high catalytic activity--compared with their contemporaries. Increased protein stability is associated with lower aggregation rates, higher soluble protein abundance and a greater capacity to evolve, and therefore, these proteins could be considered "superior" to their contemporary counterparts. In this study, we investigate the relationship between the favourable in vitro biochemical properties of reconstructed ancestral enzymes and the organismal fitness they confer in vivo. We have previously reconstructed several ancestors of the enzyme LeuB, which is essential for leucine biosynthesis. Our initial fitness experiments revealed that overexpression of ANC4, a reconstructed LeuB that exhibits high stability and activity, was only able to partially rescue the growth of a ΔleuB strain, and that a strain complemented with this enzyme was outcompeted by strains carrying one of its descendants. When we expanded our study to include five reconstructed LeuBs and one contemporary, we found that neither in vitro protein stability nor the catalytic rate was correlated with fitness. Instead, fitness showed a strong, negative correlation with estimated evolutionary age (based on phylogenetic relationships). Our findings suggest that, for reconstructed ancestral enzymes, superior in vitro properties do not translate into organismal fitness in vivo. The molecular basis of the relationship between fitness and the inferred age of ancestral LeuB enzymes is unknown, but may be related to the reconstruction process. We also hypothesise that the ancestral enzymes may be incompatible with the other, contemporary enzymes of the metabolic network.

  19. Darwin's Arguments in Favour of Natural Selection and against Special Creationism

    Nola, Robert

    2013-01-01

    In many places in "The Origin of Species", Darwin compares his own theory of Natural Selection favourably with Special Creationism which comes off as a bad second best. He does this using some version of the argument form known as "Inference to the Best Explanation". The first part of this paper is methodological. It considers Whewell's notion of…

  3. Circulating Irisin Concentrations Are Associated with a Favourable Lipid Profile in the General Population.

    Simon Oelmann

    Full Text Available Irisin is a myokine, which is mainly inversely associated with the risk for non-communicable diseases. Irisin improves cellular energy metabolism by uncoupling the mitochondrial respiratory chain resulting in increased energy expenditure using lipids. To date potential associations between irisin concentration and lipid profile are poorly understood. Therefore, this investigation aimed to evaluate potential associations between irisin and lipid levels in the general population.Data of 430 men and 537 women from the population-based Study of Health in Pomerania (SHIP-TREND with available irisin and lipid concentrations were used. Analyses of variance, linear and logistic regression models adjusted for age, HBA1c, waist circumference, physical activity, smoking, alcohol consumption, systolic blood pressure, ALAT were calculated.We detected significantly inverse associations between irisin and circulating levels of total [beta coefficient 0.21 (standard error 0.08, p = 0.01], low-density cholesterol [-0.16 (0.07, p = 0.03] and triglycerides [-0.17 (0.08, p = 0.02] for men. Females without lipid lowering medication had an inverse association between irisin and total cholesterol [-0.12 (0.06, p = 0.05]. Further, male subjects with irisin concentrations in the third tertile had an increased odds for elevated low-density cholesterol [odds ratio 1.96 (95% confidence interval 1.07-3.48, p = 0.03 and triglyceride [1.95 (1.09-3.47, p = 0.02] levels, even after exclusion of subjects with lipid lowering medication. In addition, our data revealed an annual rhythm of serum irisin levels with peak levels arise in winter and summer months.This is the first investigation to report a significant association between circulating irisin and a favourable lipid profile in the general population. This may infer that higher irisin concentrations are associated with a reduced risk for non-communicable diseases.

  4. Virus Status, Varroa Levels, and Survival of 20 Managed Honey Bee Colonies Monitored in Luxembourg Between the Summer of 2011 and the Spring of 2013

    2015-06-01

    Full Text Available Twenty managed honey bee colonies, split between 5 apiaries with 4 hives each, were monitored between the summer of 2011 and spring of 2013. Living bees were sampled in July 2011, July 2012, and August 2012. Twenty-five, medium-aged bees, free of varroa mites, were pooled per colony and date, to form one sample. Unlike in France and Belgium, Chronic Bee Paralysis Virus (CBPV has not been found in Luxembourg. Slow Bee Paralysis Virus (SBPV and Israeli Acute Paralysis Virus (IAPV levels were below detection limits. Traces of Kashmir Bee Virus (KBV were amplified. Black Queen Cell Virus (BQCV, Varroa destructor Virus-1 (VDV-1, and SacBrood Virus (SBV were detected in all samples and are reported from Luxembourg for the first time. Varroa destructor Macula- Like Virus (VdMLV, Deformed Wing Virus (DWV, and Acute Bee Paralysis Virus (ABPV were detected at all locations, and in most but not all samples. There was a significant increase in VDV-1 and DWV levels within the observation period. A principal component analysis was unable to separate the bees of colonies that survived the following winter from bees that died, based on their virus contents in summer. The number of dead varroa mites found below colonies was elevated in colonies that died in the following winter. Significant positive relationships were found between the log-transformed virus levels of the bees and the log-transformed number of mites found below the colonies per week, for VDV-1 and DWV. Sacbrood virus levels were independent of varroa levels, suggesting a neutral or competitive relationship between this virus and varroa.

    CONCLUSION: Although there are no available data in the literature to confirm or reject the contribution of the chronic nail infection to the malignant process, we emphasise the importance of this co-existence regarding the possible disguising of the malignant process. An early biopsy of a chronic persistent nail lesion may be preventive and beneficial regarding avoiding more aggressive treatments and achieving a favourable prognosis.

  8. Research on interactive genetic-geological models to evaluate favourability for undiscovered uranium resources

    Finch, W.I.; Granger, H.C.; Lupe, R.; McCammon, R.B.

    1980-01-01

    Current methods of evaluating favourability for undiscovered uranium resources are unduly subjective, quite possibly inconsistent and, as a consequence, of questionable reliability. This research is aimed at reducing the subjectivity and increasing the reliability by designing an improved method that depends largely on geological data and their statistical frequency of occurrence. This progress report outlines a genetic approach to modelling the geological factors that controlled uranium mineralization in order to evaluate the favourability for the occurrence of undiscovered uranium deposits of the type modelled. A genetic model is constructed from all the factors that describe the processes, in chronological sequence, that formed uranium deposits thought to have a common origin. The field and laboratory evidence for the processes constitute a geologic-occurrence base that parallels the chronological sequence of events. The genetic model and the geologic-occurrence base are portrayed as two columns of an interactive matrix called the ''genetic-geologic model''. For each column, eight chronological stages are used to describe the overall formation of the uranium deposits. These stages consist of (1) precursor processes; (2) host-rock formation; (3) preparation of host-rock; (4) uranium-source development; (5) transport of uranium; (6) primary uranium deposition; (7) post-deposition modification; and (8) preservation. To apply the genetic-geological model to evaluate favourability, a question is posed that determines the presence or absence of each attribute listed under the geologic-occurrence base. By building a logic circuit of the attributes according to either their essential or non-essential nature, the resultant match between a well-documented control area and the test area may be determined. The degree of match is a measure of favourability for uranium occurrence as hypothesized in the genetic model

    2012-09-25

    Life satisfaction (LS) of cerebrovascular disease survivors and their family caregivers may relate to socioeconomic factors, impaired functions, health-related quality of life (QoL), but their respective influences remain unclear. This study assessed, two years post-stroke onset, the effects of these factors on patients' LS and family caregivers' LS in Luxembourg. All stroke patients admitted to all hospitals in Luxembourg were identified by the 'Inspection Général de la Sécurité Sociale' using the only national system database for care expenditure reimbursement. Their diagnosis was confirmed by medical investigator. The sample included ninety four patients living at home having given consent (mean age 65.5 years) and sixty two main caregivers (mean age 59.3 years). Questionnaires were completed during face-to-face interviews. LS was assessed via European single question (range 1-10), survivors' QoL via Newsqol (11 dimensions), and caregivers' QoL via Whoqol-bref (4 domains) (range 0-100). Data were analysed using multiple regression models. Two years after stroke onset, 44.7% of patients suffered from impaired sensory function, 35.1% from impaired motor function, and 31.9% from impaired memory function. Mean patient' LS was 7.1/10 (SD 1.9). It was higher in women (+12.4) and lower among unemployed socioeconomically active patients (-13.1, vs. retired people). Adjusted for sex, occupation, impaired motor and memory functions, LS positively correlated with scores of Newsqol feelings, sleep, emotion, cognition and pain dimensions (slopes 0.20 to 0.31), but did not correlate with those of caregivers' Whoqol-bref domains. Family caregiver' LS was 7.2 (SD 1.7). It was lower in those with patients suffering from impaired memory function (-12.8) as well as from feelings and emotion issues (slopes 0.22). It was associated with all caregivers' Whoqol-bref domains (physical health, psychological health, environment, and social relationships) (slopes 0.53 to 0.68). Two

    2008-07-19

    To evaluate the effect of Go4it, a multidisciplinary group education programme for adolescents with overweight or obesity. Uncontrolled intervention study. At the obesity outpatient clinic of the Transmural Research and Treatment Centre for Overweight and Obese Children of the VU University Medical Center, Amsterdam, The Netherlands, a group education programme was developed for adolescents (age 12-18 year) who are overweight or obese. Obese adolescents who were referred to the obesity outpatient clinic were asked to participate. During 7 sessions (one session every two weeks) the adolescents were educated on the health consequences of obesity, diet, physical activity, energy balance, improving self-esteem and how to handle bullying and other difficult situations. All sessions were held in groups of 8-10 adolescents. In addition, two sessions were organised for the parents concerning the health consequences of obesity, diet, and physical activity. Body weight and height, glucose tolerance (by an oral glucose tolerance test; OGTT), and insulin resistance were measured at enrolment into the Go4it programme and 6 months later. In total, 93 adolescents (39 boys, 54 girls) were included with a mean age of 3.9 (SD: 1.7) years. Of those, 69 adolescents (74%) attended at least 6 out of 7 sessions of the education programme. Stabilisation or reduction in obesity levels following completion of Go4it was achieved in 51 (74%) of these participants. 50 adolescents had a second OGTT. The BMI standard deviation score (BMI-sds) decreased by 4.3% for boys (p = 0.020) and 3.3% for girls (p = 0.017). Among girls, fasting blood glucose levels decreased by an average of 0.37 mmol/l (95% CI: 0.14-0.60) and insulin concentrations decreased by an average of 299 pmol/l (95% CI: 71-528). Participation in the Go4it education programme is accompanied by a stabilisation or reduction in the level of obesity and has favourable effects on glucose and insulin metabolism.

  12. Prospecting direction and favourable target areas for exploration of large and super-large uranium deposits in China

    1993-01-01

    A host of large uranium deposits have been successively discovered abroad by means of geological exploration, metallogenetic model studies and the application of new geophysical and geochemical methods since 1970's. Thorough undertaking geological research relevant to prospecting for super large uranium deposits have attracted great attention of the worldwide geological circle. The important task for the vast numbers of uranium geological workers is to make an afford to discover more numerous large and super large uranium deposits in China. The author comprehensively analyses the regional geological setting and geological metallogenetic conditions for the super large uranium deposits in the world. Comparative studies have been undertaken and the prospecting direction and favourable target areas for the exploration of super large uranium deposits in China have been proposed

  13. The H II galaxy Hubble diagram strongly favours Rh = ct over ΛCDM

    Wei, Jun-Jie; Wu, Xue-Feng; Melia, Fulvio

    2016-12-01

    We continue to build support for the proposal to use H II galaxies (HIIGx) and giant extragalactic H II regions (GEHR) as standard candles to construct the Hubble diagram at redshifts beyond the current reach of Type Ia supernovae. Using a sample of 25 high-redshift HIIGx, 107 local HIIGx, and 24 GEHR, we confirm that the correlation between the emission-line luminosity and ionized-gas velocity dispersion is a viable luminosity indicator, and use it to test and compare the standard model ΛCDM and the Rh = ct universe by optimizing the parameters in each cosmology using a maximization of the likelihood function. For the flat ΛCDM model, the best fit is obtained with Ω _m= 0.40_{-0.09}^{+0.09}. However, statistical tools, such as the Akaike (AIC), Kullback (KIC) and Bayes (BIC) Information Criteria favour Rh = ct over the standard model with a likelihood of ≈94.8-98.8 per cent versus only ≈1.2-5.2 per cent. For wCDM (the version of ΛCDM with a dark-energy equation of state wde ≡ pde/ρde rather than wde = wΛ = -1), a statistically acceptable fit is realized with Ω _m=0.22_{-0.14}^{+0.16} and w_de= -0.51_{-0.25}^{+0.15} which, however, are not fully consistent with their concordance values. In this case, wCDM has two more free parameters than Rh = ct, and is penalized more heavily by these criteria. We find that Rh = ct is strongly favoured over wCDM with a likelihood of ≈92.9-99.6 per cent versus only 0.4-7.1 per cent. The current HIIGx sample is already large enough for the BIC to rule out ΛCDM/wCDM in favour of Rh = ct at a confidence level approaching 3σ.

  19. Analysis of conditions favourable for small vertical axis wind turbines between building passages in urban areas of Sweden

    Awan, Muhammad Rizwan; Riaz, Fahid; Nabi, Zahid

    2017-05-01

    This paper presents the analysis of installing the vertical axis wind turbines between the building passages on an island in Stockholm, Sweden. Based on the idea of wind speed amplification due to the venture effect in passages, practical measurements were carried out to study the wind profile for a range of passage widths in parallel building passages. Highest increment in wind speed was observed in building passages located on the periphery of sland as wind enters from free field. Wind mapping was performed in the island to choose the most favourable location to install the vertical axis wind turbines (VAWT). Using the annual wind speed data for location and measured amplification factor, energy potential of the street was calculated. This analysis verified that small vertical axis wind turbines can be installed in the passage centre line provided that enough space is provided for traffic and passengers.

  20. Low vascularity predicts favourable outcomes in leiomyoma patients treated with uterine artery embolization.

    Tang, Yixin; Chen, Chunlin; Duan, Hui; Ma, Ben; Liu, Ping

    2016-10-01

    To investigate the clinical factors predicting outcomes of leiomyoma treated with uterine artery embolization (UAE). A total of 183 uterine leiomyoma patients undergoing UAE were retrospectively analyzed. Patient age, characteristics of vascular supply in magnetic resonance imaging (MRI)/digital subtraction angiography (DSA), number, size and location of leiomyoma were recorded. Leiomyoma regrowth, new leiomyoma appearance and recurrence of any previously reported symptoms were carefully monitored over a mean follow-up of 30 months (median 32 months, range 12-80). Potential recurrence risk factors were analyzed by univariate and multivariate cox regression analysis. Twenty-three recurrences were recorded. The difference in the vascularity classification systems between MRI and DSA was not statistically significant (P = 0.059). High vascularity in MRI, high vascularity in DSA and multiple leiomyoma showed a significant risk of recurrence using univariate and multivariate analysis (P = 0.004, P leiomyoma recurrence (P > 0.05). Low vascularity and solitary leiomyoma indicated favourable outcomes in patients treated with UAE. • Low vascularity and solitary mass predicted favourable outcomes in UAE-treated patients. • MRI might provide information on vascularity in leiomyoma before UAE. • Variations in vascular supply, age, size, location were not associated with recurrence.

    Prognosis of patients with glioblastoma with oligodendroglial component (GBM-O) is not well defined. We report our experience of patients of GBM-O treated at our center. Between January 2007 and August 2013, out of 817 consecutive patients with glioblastoma (GBM), 74 patients with GBM-O were identified in our prospectively maintained database. An experienced neuropathologist revaluated the histopathology of all these 74 patients and the diagnosis of GBM-O was eventually confirmed in 57 patients. Patients were uniformly treated with maximal safe resection followed by focal radiotherapy with concurrent and adjuvant temozolamide (TMZ). At a median follow up of 16 months, median overall survival (OS) and progression free survival (PFS) of the entire cohort was 23 months and 13 months respectively. Near total excision was performed in 30/57 (52.6%). On univariate analysis, age GBM-O patients with a similarly treated cohort of 105 GBM patients during the same period revealed significantly better median OS in favour of GBM-O (p = 0.01). Our experience suggests patients with GBM-O have a more favourable clinical outcome as compared to GBM. Copyright © 2015 Elsevier B.V. All rights reserved.

  2. SIMPROVING THE ECONOMIC ACTIVITIES IN THE LESS FAVOURED AREAS OF ROMANIA

    Full Text Available This paper deals with finding solutions for improving the economic activities in Romania’s undeveloped areas, which still represent a major problem for this country’s economy. During 1999 and 2009, these areas were considered tax havens, due to some facilities accorded by the Government and the EU (headage compensatory allowances*, tax deductions, non-refundable funds. Many had the opportunity to invest in those regions, but no positive effect was to be seen. Tulcea County (Danube Delta area, coal mine regions, rural areas and the North-East area (Suceava and Botosani county are considered to be Romania’s less favoured areas. * The objective of these schemes is to provide a reasonable level of income for farmers where natural production conditions are least favourable so as to conserve the countryside by the prevention of further depopulation of rural areas. Compensatory allowances are payable to farmers for the keeping of cattle, sheep and goats. (www.europa.eu

    The ability to create lasting, trust-based friendships makes it possible for humans to form large and coherent groups. The recent literature on the evolution of sociality and on the network dynamics of human societies suggests that large human groups have a layered structure generated by emotionally supported social relationships. There are also gender differences in adult social style which may involve different trade-offs between the quantity and quality of friendships. Although many have suggested that females tend to focus on intimate relations with a few other females, while males build larger, more hierarchical coalitions, the existence of such gender differences is disputed and data from adults is scarce. Here, we present cross-cultural evidence for gender differences in the preference for close friendships. We use a sample of ∼112,000 profile pictures from nine world regions posted on a popular social networking site to show that, in self-selected displays of social relationships, women favour dyadic relations, whereas men favour larger, all-male cliques. These apparently different solutions to quality-quantity trade-offs suggest a universal and fundamental difference in the function of close friendships for the two sexes. PMID:25775258

  5. An evolutionary concept of polycystic ovarian disease: does evolution favour reproductive success over survival?

    Gleicher, Norbert; Barad, David

    2006-05-01

    Polycystic ovarian disease (PCOD) is currently considered as possibly the most frequent cause of female infertility. It is also closely associated with syndrome XX, which, in turn, is closely linked with premature and excessive mortality. Considering these adverse effects on reproductive success and human survival, the evolutionary survival of PCOD, itself considered by many to be a genetically transmitted condition, would, on first glance, appear surprising, since evolution usually discriminates against both of these traits. However, an analysis of some recently reported characteristics of the condition calls for the reconsideration of PCOD as a condition which, from an evolutionary viewpoint, favours decreased reproductive success. Indeed, the reported observations that patients with PCOD will resume spontaneous ovulation with even relatively minor weight loss, and experience later menopause than controls, suggests exactly the opposite. Under an evolutionary concept, PCOD can thus be seen as a 'fertility storage condition' which in fact favours human reproductive success and allows the human species to maintain fertility even during adverse environmental circumstances, such as famines.

  6. International Uranium Resources Evaluation Project (IUREP) national favourability studies: United Arab Emirates

    1977-11-01

    While most of the rocks in the United Arab Emirates are of sedimentary marine origin there are also some granites and metamorphic rock areas. It is understood that Hunting Geology and Geophysics Ltd were contracted in 1975 to carry out a mineral survey over 11,500 square kilometres utilising, among others, gamma-ray spectrometry. The results of this survey are not known. A report in 1974 of a large occurrence of uranium in Fujairah was later discredited but at least two radioactive anomalies are known in the country. The existence of granitic rocks and the appropriate conditions for calcareous duricrust formations may indicate some slight potential for uranium.

    The Arabian Shield forms the western part of the country and is composed of Precambrian metasediments of undescribed composition. The literature mentions calcareous duricrust formations in the eastern desert part of the country. This juxtaposition of possible source and duricrust is very similar to Somalia and leads to the view that the Speculative Potential may be in the 1000 to 10,000 tonnes uranium category. (author)

    In the first years of the uranium program, starting in 1948, drilling was primarily undertaken by the government. The AEC and the U.S. Geological Survey continued a modest program until the mid-1950's. The government drilled about 5-6 million feet (1.7 million meters), and a number of significant ore deposits were defined, primarily in the Uravan Mineral Belt, Colorado. Except for the early years, private drilling exceeded the government program. Drilling reached a peak of 2.8 million meters in 1957, but dropped back to 0.6 million meters in 1965 when the government purchase program had been phased out. Later, with resurgence of uranium demand it rose again to nearly 9.1 million meters in 1969. After a decline in the early 1970's, activity rose dramatically to 10.3 million meters in 1976. Total drilling through 1976 has been about 88.3 million meters. Exploration costs from 1966 through 1976 are estimated to be $679 million. During 1976, 32 percent of the drilling or 3.3 million meters was in the Wyoming Basins, with 4.5 million meters or 43 percent in the Colorado Plateau, and 0.9 million meters or 8 percent in the Gulf Coastal Plain. Total 1976 drilling was 0.9 million meters and average depth of hole 155 meters; this contrasts with 1.7 million meters and 53 meters average depth in 1960. Reserves of uranium are located in the western portion of the country with over 85 percent in the Colorado Plateau and Wyoming Basins. The Basin and Range province of Oregon, California, Nevada, Arizona, New Mexico, and Texas is receiving considerable exploration emphasis. Other areas of increasing activity include sedimentary rocks of the Great Plains and the crystalline rocks of the Rocky Mountains, Appalachian Mountains, and the Precambrian shield of Michigan and Wisconsin. Work in the new areas emphasizes geologic and geophysical assessment, so relatively little drilling has been done. When programs have matured, it is assumed that drilling effort will be accelerated. Industry surveys indicated that 10.3 Billion meters were drilled during 1976 at an estimated cost of $156.9 million. For 1977 plans are projected at 11.4 million meters at a cost of $167.8 million. Costs include land acquisition, geological and geophysical surveys, site preparation, logging, end site restoral. The uranium potential of the U.S.A. is estimated to be well in excess of 1,000,000 tonnes

    Western Samoa consists principally of two large islands with seven other smaller ones, five of which are uninhabited. No concrete geologic description could be found, but on the basis of a volcanic origin for some of the islands a category 1 uranium potential is assigned. There is no mining industry, and no government agency appears to have a geologic department. (author)

  10. International Uranium Resources Evaluation Project (IUREP) national favourability studies: Federal Republic of Germany

    1977-10-01

    The Federal Republic of Germany is situated in Central Europe. It covers an area of 250,000 square kilometres and has a population of 60 millions. The Federal Republic consists of 10 individual states. The capital of the country is Bonn. The northern and northwestern parts of the country are formed of flat lowlands, the Norddeutsche Tiefebene. Towards the south follow hilly and mountainous regions with elevations not exceeding 1000 m. In the southwestern and southeastern regions the elevations may reach 1500m in the Black Forest and Bayerischer Wald. The foreland of the Alps and the northern part of the Alps itself with elevations close to 3000 m make up the southern part of the Federal Republic. The main rivers - Rhine, Weser and Elbe - are directed towards northwest and drain the country to the North Sea. Only the southern part is drained by the southeast running river Danube. The climate is moderate, generally with frequent snow during the winter season and warm periods during the summer. The precipitation is distributed uniformly throughout the year. Due to the high industrialization a dense network of railroads, highways and motorroads exists.According to what is geologically known about the country, the chances for the discovery of large quantities of low-coast uranium resources must be considered to be limited. The potential for new discoveries of those deposits can be estimated to be around 10 000 t U. The potential for very low-grade uranium ore, such as granites, low-grade sedimentary rocks (sandstones, shales) can be estimated to range between 10,000 - 50,000 t U or possibly more taking into account very low-grade concentrations in shales. This material is not mineable under present conditions. Environmental considerations may prevent mining in the future

    1977-11-01

    The Yemen Arab Republic occupies a part of the southern Arabian Shield and has been subject to considerable faulting and movement. As far as is known no uranium exploration has ever been undertaken or is presently contemplated in the country. Uranium could occur in the Shield rocks and conditions are right for calcrete type uranium deposits. The Speculative Potential may be in category 2, i.e. between 1000 and 10,000 tonnes uranium.

    1977-12-01

    The New Hebrides consists of about 70 islands in the Southwest Pacific Ocean. The 12 largest, and main islands are volcanic cones with a few marine sediments. A manganese mining industry is presently producing but there has been no known activity in uranium exploration or mining. The area of the New Hebrides is nearly 15,000 square kilometers, and the principal industries are centered around agriculture and fishing. The uranium potential is estimated in category 1 (less than 1,000 tonnes U) (author)

  13. International Uranium Resources Evaluation Project (IUREP) national favourability studies: Republic of Korea

    1977-12-01

    The Republic of Korea, occupies the southern end of the Korean peninsula. It has a long history of mining and mineral production, and has an active and fairly well equipped Geological Survey. The country in general is quite highly mineralized with many minerals including uranium although there has been no uranium production from it yet. Uranium occurs in granites, schists, and in black carbonaceous shales. The Korean Geological survey has estimated that one ore body contains 650 tonnes U in 1,600,000 tons of ore at an average grade of 0.047 percent U 3 O 8 . Many recent reports also indicate very large resources of uranium in very low grade ranges. The uranium potential for the Republic of Korea is considered in Category 2 (1,000 - 10,000 tonnes U) in the normal IUREP context. However, a very large resource may exist in the very low grades in black shales of the country. This resource is considered as in category 6 (500,000 to 1,000,000 tonnes U). (author)

    1977-10-01

    Although uranium prospecting was commenced in the United Kingdom (area 244,813 km) at the end of the last century and was resumed just after the Second World War, it does not seem, for various reasons, despite the level of competence of its specialists and the level of instrumentation available, that the country has been adequately prospected for uranium. The small reserves discovered to date, some 7400t U for all the official NEA/lAEA categories, probably do not reflect the true uranium potential of the United Kingdom. However, they do indicate without doubt that the resources remaining to be discovered are so located that detection will be difficult. The most promising areas of investigation in our opinion are the Old Red Sandstones of the Devonian period on the one hand and the districts where the uraniferous black shales of the Cambro-Ordovician and Namurian have suffered perturbations which may have led to immobilization of their uranium content (in particular, granitizations). All the considerations put forward in this analysis lead us to place the United Kingdom in category 4 of the classification adopted for IUREP. (author)

    1977-11-01

    The Cook Islands total only 320 square kilometers in area are located in the central South Pacific, and are made up of either volcanic material or coral. Since neither rock type is considered a good host or source of uranium, the uranium potential of the Cook Islands is considered nil. (author)

  16. International Uranium Resources Evaluation Project (IUREP) national favourability studies: Sri Lanka

    1977-10-01

    Sri Lanka is essentially a detached portion of the Deccan Plateau of south India and like it, is underlain almost everywhere by hard old Precambrian rocks. Prior to 1940 there was no systematic organised geological survey work on the island. Between 1957 and 1962 a partial aerial survey and field traverses were conducted in a search for radio- active minerals. Since then a modest programme has continued. Thorianite was first discovered in placer deposits in 1903 and prospecting has found many other refractory radioactive minerals probably derived from the weathering of pegmatites. Monazite is found as an important constituent of beach placer deposits and it is estimated to have an average content of 8-10%ThO 2 and 0.3 - 0.5% U 3 O 8 . Up to 1000 tons monazite per year could be produced from the beach sand industry. Sri Lanka has had very little systematic exploration for uranium and as it is largely composed of Precambrian rocks it deserves closer attention. On the other hand it is part of a thorium rich province and there is a body of technical opinion that believes that thorium rich provinces are unlikely to contain significant uranium deposits. For these reasons it is estimated that the Speculative Potential may be within the range of 1000 to 10,000 tonnes uranium. In addition it maybe possible to produce up to 5 tonnes uranium and 100 tonnes thorium from the beach sand industry on an annual basis. (author)

  17. International Uranium Resources Evaluation Project (IUREP) national favourability studies: The Netherlands

    1978-01-01

    The Netherlands is part of the lowlands of Western Europe formed by negative crustal movements that have been offset by sedimentation. This specific area stretching from western Belgium into north-western Germany forms part of an epicontinental area that has been relatively stable since the end of the Hercynian orogeny. In Holland the subsidence has generally been small through- out the Mesozonic and Cenozoic though interrupted by short periods of erosion and non-subsidence. Thus the general geology of the Netherlands is dominated by the fact that throughout the Tertiary and Quaternary what now comprises the Netherlands formed part of a subsiding basin. Most of the surface geology of the country is dominated by f luvio-glacial shallow marine and lacoustine deposits. Prospecting for radioactive minerals in the Netherlands has been very limited. Some work has been carried out by the Geological Survey and by private consultants but this was very preliminary. To-date no uranium reserves or resources have been identified in the Netherlands. One small uranium occurrence has been recorded in Zeeland near Walcheren where some small uranium concentrations were found in association with phosphatic nodules. Apart from very limited targets in the Cretaceous and small phosphatic uranium associations there are no apparent uranium exploration targets in the Netherlands. On this basis we would, at this time, place the uranium potential of the Netherlands in Group I of the IUREP classification

    1977-12-01

    The Solomon Islands have an area of about 30,000 square kilometers. The larger islands are volcanic and contain a small variety of minerals, some of which may eventually be economically recoverable. A large phosphate deposit may also be mined at some future date. Specific geologic information is very difficult to find, but on the basis of what little is available a small potential is deduced to be in Category 2 (l,000 - 10,000 tonnes U). (author

  19. International Uranium Resources Evaluation Project (IUREP) national favourability studies: Belize (Former British Honduras)

    1977-08-01

    Belize is a well-forested area of 22,960 square kilometers. Its capital is Belmopan. The country is generally flat north of the capital city. The flat, swampy Caribbean Coast of Belize gradually ascends to the low peaks of the Maya and Cockscomb Mountains (elevation to 1,120 meters). The area south of the Maya Mountains is much more rugged than the area to the north. The country is drained by seventeen rivers, the chief ones being the Belize, Hondo, New, Sibun, Monkey and Moho. There is 'hurricane danger in the July-October period. Belize has reportedly been surveyed by Gamma Ray Spectrometer for phosphates which probably would have contained sufficient uranium to be detectable. The survey traversed about 1,000 line kms along major north-south and east-west roads as well as many secondary roads and trails. The uranium readings ranged from 0. to 9.9 ppm with a uranium content of 1-2 ppm in the limestone areas and 2-7 ppm in the alluvium-covered areas. The U/Th ratio varied from 0.11 to 1.65. A recent traverse across the Mountain Pine Ridge batholith gave one reading as high as 36 ppm but the average was about 9-10 ppm. The upper 1000-3000 feet of core and cuttings from nine deep oil wells were checked for phosphates and uranium. Most of the core and cuttings were almost pure limestones. The P 2 0 3 content was less than 0.05 percent and no uranium was detected. It is very doubtful that any significant uranium occurrences will be found in the sediments surrounding the Maya Mountain uplift. However, there is a slight chance that uranium might occur in the granites and pegmatites in the Maya Mountains. The potential of Belize is estimated to be in the less than 1.000 tonnes uranium range, considering the restricted range, of geologic environments encountered there

    1977-11-01

    The report deals almost exclusively with Greenland. A major omission is any broad description of the geology of the island. One which can be recommended is 'A survey of the economic geology of Greenland' by B.J. Nielsen published by the Geological Survey of Greenland. Nielsen has also published several articles on the uranium occurrences in Greenland, some of which are noted in the references. A review of the geology is necessary in order to determine how the known occurrences fit into the pattern of uranium mineralisation in the North Atlantic regions and Canada, and to suggest further potential by analogy with these regions. Maps are significantly also lacking and three suitable examples are attached. Additions to the general map would be the areas examined and the extent of airborne radiometry. A further major omission is a definition of the meaning of potential resources, especially as 250,000 tonnes are claimed for the lujavrites at present and a future potential of 500,000 tonnes. I presume that this is the contained uranium which can be calculated as being present in the rock units, rather than any estimate of the amount of uranium which could be recovered economically. The figures for RAH and EAR at Kvanefjeld could conveniently be updated (Nov. 77) to RAH 15,750 t U, EAR 10,000 t U, TOTAL 25,750 t U. As these alkalic rocks are confined to the Garder province of the Ketilidian mobile belt some more definite indication of similar uraniferous types could be made from the excellent published maps and lead to more realistic estimates using the NURE formulae

    The potential for uranium deposits appears to be poor in Cambodia. It is largely alluvium. Uranium may occur in discordant deposits in metamorphics and intrusives in the Cardamon and Elephant Hills in the south, and in placers of U/TH minerals in the delta or banks of the Mekong River. The potential is in category 1 (less than 1000 tonnes U ). (author)

The high islands are commonly volcanic in origin while the lower islands are generally coral. They lie in the Tropic zone and are generally warm. Rainfall ranges from a few centimeters per year to as much as 1000. Because of their volcanic or coral origins, the islands of French Polynesia are not considered to have a uranium potential.

    Plasminogen activator inhibitor 1 (PAI-1) overexpression is an important prognostic and predictive biomarker in human breast cancer. SERBP1, a protein that is supposed to regulate the stability of PAI-1 mRNA, may play a role in gynaecological cancers as well, since upregulation of SERBP1 was described in ovarian cancer recently. This is the first study to present a systematic characterisation of SERBP1 expression in human breast cancer and normal breast tissue at both the mRNA and the protein level. Using semiquantitative realtime PCR we analysed SERBP1 expression in different normal human tissues (n = 25), and in matched pairs of normal (n = 7) and cancerous breast tissues (n = 7). SERBP1 protein expression was analysed in two independent cohorts on tissue microarrays (TMAs), an initial evaluation set, consisting of 193 breast carcinomas and 48 normal breast tissues, and a second large validation set, consisting of 605 breast carcinomas. In addition, a collection of benign (n = 2) and malignant (n = 6) mammary cell lines as well as breast carcinoma lysates (n = 16) were investigated for SERBP1 expression by Western blot analysis. Furthermore, applying non-radioisotopic in situ hybridisation a subset of normal (n = 10) and cancerous (n = 10) breast tissue specimens from the initial TMA were analysed for SERBP1 mRNA expression. SERBP1 is not differentially expressed in breast carcinoma compared to normal breast tissue, both at the RNA and protein level. However, recurrence-free survival analysis showed a significant correlation (P = 0.008) between abundant SERBP1 expression in breast carcinoma and favourable prognosis. Interestingly, overall survival analysis also displayed a tendency (P = 0.09) towards favourable prognosis when SERBP1 was overexpressed in breast cancer. The RNA-binding protein SERBP1 is abundantly expressed in human breast cancer and may represent a novel breast tumour marker with prognostic significance. Its potential involvement in the

    Powell, Justin J W; Dusdal, Jennifer

    2017-01-01

    Charting significant growth in science production over the 20th century in four European Union member states, this neo-institutional analysis describes the development and current state of universities and research institutes that bolster Europe's position as a key region in global science. On-going internationalization and Europeanization of higher education and science has been accompanied by increasing competition as well as collaboration. Despite the policy goals to foster innovation and further expand research capacity, in cross-national and historical comparison neither the level of R&D investments nor country size accounts completely for the differential growth of scientific productivity. Based on a comprehensive historical database from 1900 to 2010, this analysis uncovers both stable and dynamic patterns of production and productivity in Germany, France, Belgium, and Luxembourg. Measured in peer-reviewed research articles collected in Thomson Reuters' Science Citation Index Expanded, which includes journals in the fields of Science, Technology, Engineering, Mathematics, and Health, we show the varying contributions of different organizational forms, especially research universities and research institutes. Comparing the institutionalization pathways that created the conditions necessary for continuous and strong growth in scientific productivity in the European center of global science emphasizes that the research university is the key organizational form across countries.

  6. Identifying the origins of local atmospheric deposition in the steel industry basin of Luxembourg using the chemical and isotopic composition of the lichen Xanthoria parietina.

    2008-11-01

    Trace metal atmospheric contamination was assessed in one of the oldest European industrial sites of steel production situated in the southern part of the Grand-Duchy of Luxembourg. Using elemental ratios as well as Pb, Sr, and Nd isotopic compositions as tracers, we found preliminary results concerning the trace metal enrichment and the chemical/isotopic signatures of the most important emission sources using the lichen Xanthoria parietina sampled at 15 sites along a SW-NE transect. The concentrations of these elements decreased with increasing distance from the historical and actual steel-work areas. The combination of the different tracers (major elements, Rare Earth Element ratios, Pb, Sr and Nd isotopes) enabled us to distinguish between three principal sources: the historical steel production (old tailings corresponding to blast-furnace residues), the present steel production (industrial sites with arc electric furnace units) and the regional background (baseline) components. Other anthropogenic sources including a waste incinerator and major roads had only weak impacts on lichen chemistry and isotopic ratios. The correlation between the Sr and Nd isotope ratios indicated that the Sr-Nd isotope systems represented useful tools to trace atmospheric emissions of factories using scrap metal for steel production.

  7. Comparison of Operational Subsidies on Less Favoured Areas in EU Countries

    Jana Lososová

    2016-01-01

    Full Text Available This article is aimed at an analysis of operational subsidies on the Less Favoured Areas (LFA in the European Union countries. With the help of cluster analysis, the EU countries were divided into groups and, using correlation and regression analyses, the relations between defined indicators were evaluate. The indicators of FADN EU related to the cultivated land area were completed with relative indicators. Some differences were proved in subsidy effectiveness between particular groups of the countries. The amount of operational subsidies only has a positive impact on subsidised costs in the mountain LFAs. Worse productive and climate conditions increase the dependence of the output on subsidies related to cost effectiveness. No dependence of the output share of subsidies and the subsidised costs was proven in all groups.

  8. The shift of the public opinion to the favour of nuclear energy in Slovenia

    Lengar, I.; Nemec, T.

    2001-01-01

    In late August and early September of 1999, nuclear energy topics occupied a central place in the Slovenian media because of the transport of two new steam generators to the Krsko nuclear power plant, and also due to the protest action of an Austrian Greenpeace group. Before these events, the public opinion in Slovenia was not in favour or nuclear energy and Greenpeace had a good reputation. In September it has lost much credibility because of their clumsy action of protest, and in just one month this caused a shift of public opinion in Slovenia towards support of Slovenia's only nuclear power plant. The Greenpeace protest action occurred during the transport of the two new steam generators to Krsko. By replacement of the old steam generators the operation of the Krsko NPP will be extended until 2023. The transport envoy travelled during the first half of September '99 across a considerable part of Slovene territory, passing by the capital of Ljubljana. (authors)

    The value of the tensor-to-scalar ratio r in the region allowed by the latest Planck 2015 measurements can be associated to a large variety of inflationary models. We discuss here the potential of future Cosmic Microwave Background cosmological observations in disentangling among the possible theoretical scenarios allowed by our analyses of current Planck temperature and polarization data. Rather than focusing only on r, we focus as well on the running of the primordial power spectrum, α{sub s} and the running thereof, β{sub s}. If future cosmological measurements, as those from the COrE mission, confirm the current best-fit value for β{sub s} ∼> 10{sup −2} as the preferred one, it will be possible to rule-out the most favoured inflationary models.

    Full Text Available Diabetes mellitus is not only a medical, but also a public issue. The number of people with diabetes is increasing every year. Diabetes causes complications of diseases. In addition to infertility issues and foot injuries that worsen the health condition, patients develop diabetic retinopathy, diabetic neuropathy, chronic kidney disease, cardiovascular diseases (strokes, ischemic heart diseases, peripheral vascular diseases. Accordingly, training courses for patients and focus on the health of the patients themselves are very important. The object of the research is training of persons with diabetes mellitus and skills favourable to health that help to prevent complications. The aim of the article is to reveal the process of learning of patients with diabetes and the application of skills favourable to health, which help to prevent complications in life. Tasks: 1 determine what kind of training courses are organized in Lithuania for persons with diabetes mellitus; 2 determine what kind of knowledge about health and disease control is provided by medical personnel; 3 reveal what kind of knowledge about health and what skills patients adapt in everyday life. Methods of research: theoretical – analysis of scientific literature, generalization; empirical – questionnaire survey, data analysis was performed by using the SPSS 23.0 program. The t-test was used to compare averages between groups, significant difference was considered to be p < 0,05. Data analysis was performed by applying calculations of non-parametric and parametric criteria. There were 61 patients with diabetes mellitus, aged from 13 to 78 years, who participated in the research. The research sought to reveal what training courses are organized for persons with diabetes mellitus and how patients themselves preserve their health. During the research, participants were questioned about the training courses they have attended; how patients with diabetes mellitus control their disease

  14. Centaurs, Pegasus, Sherlock Holmes: Against the Prejudice in Favour of the Real

    Travanini Cristina

    2016-12-01

    Full Text Available Meinong’s thought has been rediscovered in recent times by analytic philosophy: his object theory has significant consequences in formal ontology, and especially his account of impossible objects has proved itself to be decisive in a wide range of fields, from logic up to ontology of fiction. Rejecting the traditional ‘prejudice in favour of the real’, Meinong investigates what there is not: a peculiar non-existing object is precisely the fictional object, which exemplifies a number of properties (like Sherlock Holmes, who lives in Baker Street and is an outstanding detective without existing in the same way as flesh-and-blood detectives do. Fictional objects are in some sense incomplete objects, whose core of constituent properties is not completely determined. Now, what does it imply to hold that a fictional object may also occur in true statements? We shall deal with the objections raised by Russell and Quine against Meinong’s view, pointing out limits and advantages of both perspectives.

    The analyses of geographic variations in the prevalence of major chronic conditions, such as overweight and obesity, are an important public health tool to identify "hot spots" and inform allocation of funding for policy and health promotion campaigns, yet rarely performed. Here we aimed at exploring, for the first time in Luxembourg, potential geographic patterns in overweight/obesity prevalence in the country, adjusted for several demographic, socioeconomic, behavioural and health status characteristics. Data came from 720 men and 764 women, 25-64 years old, who participated in the European Health Examination Survey in Luxembourg (2013-2015). To investigate the geographical variation, geo-additive semi-parametric mixed model and Bayesian modelisations based on Markov Chain Monte Carlo techniques for inference were performed. Large disparities in the prevalence of overweight and obesity were found between municipalities, with the highest rates of obesity found in 3 municipalities located in the South-West of the country. Bayesian approach also underlined a nonlinear effect of age on overweight and obesity in both genders (significant in men) and highlighted the following risk factors: 1. country of birth for overweight in men born in a non-European country (Posterior Odds Ratio (POR): 3.24 [1.61-8.69]) and women born in Portugal (POR: 2.44 [1.25-4.43]), 2. low educational level (secondary or below) for overweight (POR: 1.66 (1.06-2.72)] and obesity (POR:2.09 [1.05-3.65]) in men, 3. single marital status for obesity in women (POR: 2.20 [1.24-3.91]), 4.fair (men: POR: 3.19 [1.58-6.79], women: POR: 2.24 [1.33-3.73]) to very bad health perception (men: POR: 15.01 [2.16-98.09]) for obesity, 5. sleeping more than 6 hours for obesity in unemployed men (POR: 3.66 [2.02-8.03]). Protective factors highlighted were: 1. single marital status against overweight (POR: [0.60 (0.38-0.96)]) and obesity (POR: 0.39 [0.16-0.84]) in men, 2. the fact to be widowed against overweight in

    This Université du Québec en Outaouais study examined professionals' attitudes towards fathers, their perceived self-efficacy when working with them and their perceptions of the importance of including fathers in family interventions. Professionals in Québec, Canada, working in childcare fields such as education, social services, health, community services and management answered a self-report questionnaire between 2013 and 2015. The 296 respondents (90% females) had a mean age of 39 (20-65), were from urban, semi-urban and rural settings and provided services to families with children up to five years of age. Social service professionals perceived fathers more negatively than did other professionals. Even though male professionals perceived fathers more negatively, they felt more confident working with them than did their female counterparts. Positive perceptions of fathers were associated with more favourable attitudes towards including them in family interventions, and this association was mediated by the professionals' perceptions of their own self-efficacy. The most negative attitudes were reported by social service professionals. Male professionals viewed fathers more negatively but were more confident working with them than were female colleagues. Improving professionals' perceptions of fathers could help to promote their inclusion in family interventions. ©2017 Foundation Acta Paediatrica. Published by John Wiley & Sons Ltd.

  17. Organic Farming Favours Insect-Pollinated over Non-Insect Pollinated Forbs in Meadows and Wheat Fields

    Batáry, Péter; Sutcliffe, Laura; Dormann, Carsten F.; Tscharntke, Teja

    2013-01-01

    The aim of this study was to determine the relative effects of landscape-scale management intensity, local management intensity and edge effect on diversity patterns of insect-pollinated vs. non-insect pollinated forbs in meadows and wheat fields. Nine landscapes were selected differing in percent intensively used agricultural area (IAA), each with a pair of organic and conventional winter wheat fields and a pair of organic and conventional meadows. Within fields, forbs were surveyed at the edge and in the interior. Both diversity and cover of forbs were positively affected by organic management in meadows and wheat fields. This effect, however, differed significantly between pollination types for species richness in both agroecosystem types (i.e. wheat fields and meadows) and for cover in meadows. Thus, we show for the first time in a comprehensive analysis that insect-pollinated plants benefit more from organic management than non-insect pollinated plants regardless of agroecosystem type and landscape complexity. These benefits were more pronounced in meadows than wheat fields. Finally, the community composition of insect-pollinated and non-insect-pollinated forbs differed considerably between management types. In summary, our findings in both agroecosystem types indicate that organic management generally supports a higher species richness and cover of insect-pollinated plants, which is likely to be favourable for the density and diversity of bees and other pollinators.

  18. Candidate genes and favoured loci: strategies for molecular genetic research into schizophrenia, manic depression, autism, alcoholism and Alzheimer's disease.

    Gurling, H

    1986-01-01

    It is argued that further research to achieve more detailed diagnostic systems in many psychiatric disorders is unlikely to be productive without taking genetic effects into account. Even when this is done, for example when carrying out segregation analysis to determine a mode of genetic transmission, mental illnesses often pose specific problems that preclude accurate analysis. Because techniques in molecular biology and genetics have made it possible to study gene effects in human disease systematically it should now be possible to specify the genes that are involved. When this has been achieved then a diagnostic system based on genetic causation can develop. This will have the advantage of helping to pinpoint environmental factors more accurately. Specific strategies will need to be adopted to overcome uncertain modes of inheritance, incomplete or non-penetrance of disease alleles and disease heterogeneity. Highly speculative hypotheses can be put forward for a locus causing Alzheimer's disease on a portion of the long arm of chromosome 21. For autism it is plausible that there is a disease locus at or near the fragile X site on the X chromosome. A locus for manic depression has been very tentatively mapped using DNA markers to chromosome 11 and in a small proportion of families DNA markers have also shown some evidence for X linkage. Schizophrenia does not seem to be associated with any favoured loci. Candidate genes for schizophrenia include those encoding dopamine, other neurotransmitter receptors or enzymes and various neuropeptides such as enkephalin and beta endorphin.

  19. Sheep and Goat Farming in Greece: Implications and Challenges for the Sustainable Development of Less Favoured Areas

    2013-10-01

    Full Text Available Sheep and goat farming is considered to be one of the most dynamic sectors of the rural economy in Greece, both in terms of employment and overall income. The aim of this paper is to review the levels of sustainability in the small ruminant production systems in two Less Favoured Areas of Greece (LFAs: (1 in the mountainous areas of Epirus, and (2 in the island of Lesvos. In this context, the characteristics of the production systems that have significant impact on the sustainable development of rural areas under study are underlined. The sustainability is examined by the ecological, social and economic points of view, supplemented with cultural and regional elements. The ultimate purpose is to conclude with the challenges for the future rural development in LFAs through the sustainable development of sheep and goat farming. Data is based on surveys undertaken by the SEE-ERA.NET PLUS ‘INDI_SHEEP TRADI_CHEESE’ Project and the ARIMNET ‘DoMEsTIc’ Project, still in process.

    Full Text Available Statistical downscaling is used to improve the knowledge of spatial distributions from broad–scale to fine–scale maps with higher potential for conservation planning. We assessed the effectiveness of downscaling in two commonly used species distribution models: Maximum Entropy (MaxEnt and the Favourability Function (FF. We used atlas data (10 x 10 km of the fire salamander Salamandra salamandra distribution in southern Spain to derive models at a 1 x 1 km resolution. Downscaled models were assessed using an independent dataset of the species’ distribution at 1 x 1 km. The Favourability model showed better downscaling performance than the MaxEnt model, and the models that were based on linear combinations of environmental variables performed better than models allowing higher flexibility. The Favourability model minimized model overfitting compared to the MaxEnt model.

    To improve on the existing risk-stratification systems for prostate cancer. This was a retrospective investigation including 2 248 patients undergoing dose-escalated external beam radiotherapy (EBRT) at a single institution. We separated National Comprehensive Cancer Network (NCCN) intermediate-risk prostate cancer into 'favourable' and 'unfavourable' groups based on primary Gleason pattern, percentage of positive biopsy cores (PPBC), and number of NCCN intermediate-risk factors. Similarly, NCCN high-risk prostate cancer was stratified into 'standard' and 'very high-risk' groups based on primary Gleason pattern, PPBC, number of NCCN high-risk factors, and stage T3b-T4 disease. Patients with unfavourable-intermediate-risk (UIR) prostate cancer had significantly inferior prostate-specific antigen relapse-free survival (PSA-RFS, P prostate cancer-specific mortality (PCSM, P prostate cancer. Similarly, patients with very high-risk (VHR) prostate cancer had significantly worse PSA-RFS (P prostate cancer. Moreover, patients with FIR and low-risk prostate cancer had similar outcomes, as did patients with UIR and SHR prostate cancer. Consequently, we propose the following risk-stratification system: Group 1, low risk and FIR; Group 2, UIR and SHR; and Group 3, VHR. These groups have markedly different outcomes, with 8-year distant metastasis rates of 3%, 9%, and 29% (P < 0.001) for Groups 1, 2, and 3, respectively, and 8-year PCSM of 1%, 4%, and 13% (P < 0.001) after EBRT. This modified stratification system was significantly more accurate than the three-tiered NCCN system currently in clinical use for all outcomes. Modifying the NCCN risk-stratification system to group FIR with low-risk patients and UIR with SHR patients, results in modestly improved prediction of outcomes, potentially allowing better personalisation of therapeutic recommendations. © 2017 The Authors BJU International © 2017 BJU International Published by John Wiley & Sons Ltd.

  4. Multi-criteria analysis of innovation policies in favour of solar mobility in France by 2030

    Popiolek, Nathalie; Thais, Françoise

    2016-01-01

    As part of France's political intentions to reduce CO_2 emissions in building and transport, this work offers an analysis from the perspective of a public authority on the various innovation policies for the deployment of electric vehicles powered by solar photovoltaic electricity (PV) by the year 2030. This innovation involves enhancing the synergy between buildings and mobility by associating positive energy houses with electric vehicles. The vehicle battery, charged primarily using PV electricity, could also provide a way of storing intermittent solar-generated electricity for later use. The aim of this article is to implement a decision-making model for public administration which can select the best innovation policies based on a number of criteria reflecting their major goals in terms of policies relating to energy, economics, social cohesion and “factor 4″ (to reduce greenhouse gas emissions by a factor of 4 by 2050 compared with 1990 levels). The methodology developed herein has been applied to a concrete case, with some resulting recommendations which may be of use for the public authorities: simultaneously combine research in favour of solar mobility technologies and apply a relatively high carbon tax. Such recommendations are mitigated by the choice of the data set and the methodological shortcomings. - Highlights: • Public Policies are examined in order to deploy solar mobility in France by 2030. • A multi-criteria decision making model is implemented to select the best policies. • For each policy, 8 criteria are evaluated compared to the business as usual policy. • Assumptions about decision-making environment are combined to define future scenarios. • The best policies are the R&D support on technologies with a high carbon tax.

  5. Harmful and favourable ultraviolet conditions for human health over Northern Eurasia

    Chubarova, Nataly; Zhdanova, Ekaterina

    2014-05-01

    We provide the analysis of the spatial and temporal distribution of ultraviolet (UV) radiation over Northern Eurasia taking into account for both its detrimental (erythema and eye-damage effects) and favourable (vitamin D synthesis) influence on human health. The UV effects on six different skin types are considered in order to cover the variety of skin types of European and Asian inhabitants. To better quantifying the vitamin D irradiance threshold we accounted for an open body fraction S as a function of effective air temperature. The spatial and temporal distribution of UV resources was estimated by radiative transfer (RT) modeling (8 stream DISORT RT code) with 1x 1 degree grid and monthly resolution. For this purpose special datasets of main input geophysical parameters (total ozone content, aerosol characteristics, surface UV albedo, UV cloud modification factor) have been created over the territory of Northern Eurasia, which can be of separate interest for the different multidisciplinary scientific applications over the PEEX domain. The new approaches were used to retrieve aerosol and cloud transmittance from different satellite and re-analysis datasets for calculating the solar UV irradiance at ground. Using model simulations and some experimental data we provide the altitude parameterization for different types of biologically active irradiance in mountainous area taking into account not only for the effects of molecular scattering but for the altitude dependence of aerosol parameters and surface albedo. Based on the new classification of UV resources (Chubarova, Zhdanova, 2013) we show that the distribution of harmful (UV deficiency and UV excess) and favorable UV conditions is regulated by various geophysical parameters (mainly, total ozone, cloudiness and open body fraction) and can significantly deviate from latitudinal dependence. The interactive tool for providing simulations of biologically active irradiance and its attribution to the different

  6. Heterosis may result in selection favouring the products of long-distance pollen dispersal in Eucalyptus.

    João Costa E Silva

    Full Text Available Using native trees from near the northern and southern extremities of the relatively continuous eastern distribution of Eucalyptus globulus in Tasmania, we compared the progenies derived from natural open-pollination (OP with those generated from within-region and long-distance outcrossing. Controlled outcrossing amongst eight parents - with four parents from each of the northern and southern regions - was undertaken using a diallel mating scheme. The progeny were planted in two field trials located within the species native range in southern Tasmania, and their survival and diameter growth were monitored over a 13-year-period. The survival and growth performances of all controlled cross types exceeded those of the OP progenies, consistent with inbreeding depression due to a combination of selfing and bi-parental inbreeding. The poorer survival of the northern regional (♀N♂N outcrosses compared with the local southern regional outcrosses (♀S♂S indicated differential selection against the former. Despite this mal-adaptation of the non-local ♀N♂N crosses at both southern sites, the survival of the inter-regional hybrids (♀N♂S and ♀S♂N was never significantly different from that of the local ♀S♂S crosses. Significant site-dependent heterosis was detected for the growth of the surviving long-distance hybrids. This was expressed as mid-parent heterosis, particularly at the more northern planting site. Heterosis increased with age, while the difference between the regional ♀N♂N and ♀S♂S crosses remained insignificant at any age at either site. Nevertheless, the results for growth suggest that the fitness of individuals derived from long-distance crossing may be better at the more northern of the planting sites. Our results demonstrate the potential for early-age assessments of pollen dispersal to underestimate realised gene flow, with local inbreeding under natural open-pollination resulting in selection favouring the

  7. Does a person selectively recall the good or the bad from their personal past? It depends on the recall target and the person's favourability of self-views.

    In three studies, participants remembered real-life behaviours at Time 1 and attempted to recall them at Time 2. When the recall target was the self, a positivity bias emerged: self-positivity. In Study 3, self-positivity extended to an individual (target) who was liked by the participant, but did it not extend to a disliked target. For this latter target, a negativity bias emerged. For recall targets that were participants' acquaintances, self-positivity in recall was also eliminated in Studies 1 and 3, and a negativity bias in recall emerged in Study 2. Finally, in Study 2 (but not Study 3), the favourability of participants' self-view predicted the magnitude of the self-positivity in self-recall, but it did not predict valence effects in other-recall. Taken together, the results indicate that the link between behaviour valence and recall is moderated by the recall target and the favourability of one's self-view.

    Full Text Available Abstract Aim To analyse the relationships between mental health and employment commitment among prisoners and the long-term unemployed (LTU trying to return to work. Method Fifty-two of 62 male inmates of a semi-open prison (Givenich Penitentiary Centre, the only such unit in Luxembourg, and 69 LTU registered at the Luxembourg Employment Administration completed a questionnaire exploring: 1 mental health (measured by means of scales GHQ12 and CES-D; 2 employment commitment; 3 availability of a support network, self-esteem, empowerment; and 4 socio-demographic characteristics. Results Compared with LTU, inmates were younger, more had work experience (54.9% vs 26.1%, and more were educated to only a low level (71.1% vs 58.0%. The link between employment commitment and mental health in the LTU was the opposite of that seen among the prisoners: the more significant the perceived importance of employment, the worse the mental health (GHQ12 p = 0.003; CES-D p Conclusion The two groups clearly need professional support. Future research should further investigate the link between different forms of professional help and mental health. Randomized controlled trials could be carried out in both groups, with interventions to improve work commitment for prisoners and to help with getting a job for LTU. For those LTU who value employment but cannot find it, the best help may be psychological support.

  9. Impact of Patients' Communication with the Medical Practitioners, on Their Adherence Declared to Preventive Behaviours, Five Years after a Coronary Angiography, in Luxembourg.

    Michèle Baumann

    Full Text Available Patients of the National Institute of Cardiac Surgery and Interventional Cardiology in Luxembourg who underwent coronary angiography were surveyed for hypertension, hypercholesterolemia, diabetes and overweight/obesity between 2008/9 and 2013/4. For each cardiovascular risk factor (CVRFs, we analysed the associations between the quality of the patients' communication with the medical practitioner and their adherence declared to preventive behaviours.1,289 completed a self-administered questionnaire on communication with the medical practitioner (P'Com-5 items scale; Cronbach 0.87. 61.8% stopped smoking, 57.9% reduced or stopped their consumption of salt, 71.9% of fat, and 62.8% of sugar, and whereas 65% increased their consumption of fruit and vegetables and 19.8% increased their physical activity. Around 37% reported having made changes following their doctor's advice. 90% were followed by a cardiologist and 95.9% by an attending physician.No link was observed between declaration of physical activity, smoking, fats, and quality of communication. Significant associations: for increased consumption of fruit and vegetables was linked with the quality of doctor-patient communication when patients were overweight (OR = 1.081, obese (OR = 1.130, hypercholesterolemic (OR = 1.102, hypertensive (OR = 1.084 or diabetic (OR = 1.103. Reduction in salt intake was linked only to patients with hypertension (OR = 1.102, whereas reduction or cessation of sugar consumption was linked to overweight (OR = 1.093, and more so obese, (OR = 1.106, hypercholesterolemics (OR = 1.103 and diabetics (OR = 1.173.Good doctor-patient communication was related to nutrition, particularly increased consumption of fresh fruits and vegetables. Accurate perception of CVRFs by both patients and medical practitioners is essential for CV protection. The aim of instructing patients is to encourage them to make informed decisions about how to change their lifestyle. In routinely, P

  10. Zinc ions regulate opening of tight junction favouring efflux of macromolecules via the GSK3β/snail-mediated pathway.

    Zinc is an essential trace element presenting in particularly high concentration in the brain. In some regions, e.g. lateral amygdala, subiculum and hippocampus, rapidly-exchangeable zinc may transiently reach even up to 600 μM. To explore the possible roles of high-concentration Zn 2+ in regulating the blood-brain barrier (BBB), we investigated the effects of Zn 2+ on the functions and structures of the tight junction (TJ) with an in vitro model of a Madin-Darby canine kidney (MDCK) cell monolayer. The experimental results indicated that high concentrations (>200 μM) of Zn 2+ can affect the TJ integrity in a polarized manner. Basolateral addition of Zn 2+ led to reversible TJ opening with pore paths of r ∼ 2 nm or more depending on Zn 2+ concentration. The efflux/influx ratios of different sized probes were found to be ∼4.6 for FD4 (M W 4000) and ∼1.8 for Eu-DTPA (M W 560), suggesting that the Zn 2+ -induced paracelluar channels favour efflux especially for macromolecules. Further mechanistic studies revealed that the elevated intracellular Zn 2+ taken from the basolateral side can increase phosphorylation of glycogen synthase kinase (GSK) 3β, primarily due to the inhibition of calcineurin (CaN), thus resulting in the elevation of the snail transcriptional repressors. Subsequently, Zn 2+ can cause the down-regulation of claudin-1, breakage of occludin and ZO-1 rings, and collapse of basolateral F-actin structures. These overall factors result in the formation of a trumpet-like paracellular channel, which allows asymmetric solute permeation. The ERK1/2 and JNK1/2 pathways may also be involved in the Zn 2+ -induced TJ opening process, while the activation of matrix metalloproteinase was not observed. Our results may suggest a potential role of zinc in regulation of BBB permeability associated with brain clearance of metabolites through the glymphatic system.

    At the present time, all the groups of people examined are not belonging to high risk groups or groups capable of spreading the disease either among colleagues of the profession or users of products or services they are providing. Consequently it will be important to better select in the future the high risk groups. It will be probably necessary to abrogate the examination of future couples. There is presently a project to be adopted in the near future stipulating that mass radiological examinations for prevention of diseases have to be approved by the Ministry of Health, only if they are medically and epidemiologically justified

  16. Foliar photochemical processes and carbon metabolism under favourable and adverse winter conditions in a Mediterranean mixed forest, Catalonia (Spain)

    Sperlich, D.; Chang, C. T.; Peñuelas, J.; Gracia, C.; Sabaté, S.

    2014-10-01

    Evergreen trees in the Mediterranean region must cope with a wide range of environmental stresses from summer drought to winter cold. The mildness of Mediterranean winters can periodically lead to favourable environmental conditions above the threshold for a positive carbon balance, benefitting evergreen woody species more than deciduous ones. The comparatively lower solar energy input in winter decreases the foliar light saturation point. This leads to a higher susceptibility to photoinhibitory stress especially when chilly (Arbutus unedo L.). Therefore, we collected twigs from the field during a period of mild winter conditions and after a sudden cold period. After both periods, the state of the photosynthetic machinery was tested in the laboratory by estimating the foliar photosynthetic potential with CO2 response curves in parallel with chlorophyll fluorescence measurements. The studied evergreen tree species benefited strongly from mild winter conditions by exhibiting extraordinarily high photosynthetic potentials. A sudden period of frost, however, negatively affected the photosynthetic apparatus, leading to significant decreases in key physiological parameters such as the maximum carboxylation velocity (Vc, max), the maximum photosynthetic electron transport rate (Jmax), and the optimal fluorometric quantum yield of photosystem II (Fv/Fm). The responses of Vc, max and Jmax were highly species specific, with Q. ilex exhibiting the highest and P. halepensis the lowest reductions. In contrast, the optimal fluorometric quantum yield of photosystem II (Fv/Fm) was significantly lower in A. unedo after the cold period. The leaf position played an important role in Q. ilex showing a stronger winter effect on sunlit leaves in comparison to shaded leaves. Our results generally agreed with the previous classifications of photoinhibition-tolerant (P. halepensis) and photoinhibition-avoiding (Q. ilex) species on the basis of their susceptibility to dynamic

  17. Favourable environments for the deposition of uranium in the Subandean Belt and the Amazon Plain of Peru

    Canepa, L.; Rosado, F.

    1981-01-01

    The area described is located between the east flank of the eastern Cordillera on the territorial limits with Ecuador, Colombia, Brazil and Bolivia. It covers the morphological areas called sub-Andean zone and Amazon plain. The physiographic characteristics change from west to east. In the eastern Cordillera the morphology is rough, with altitudes of 5000 m. Descending to sub-Andean, it presents a moderate topography with low hills between 1000 and 2500 m. Further east the Amazon plain forms an extensive peneplain with altitudes of 400 m. The stratigraphy of the area includes rocks with ages from the Precambrian (eastern Cordillera) to recent. Outcrops of the Palaeozoic formations are found to the east of the eastern Cordillera. Rocks that belong to the Mesozoic and Cenozoic are extensively distributed in the area, as deposits of continental or deltaic facies. The geological evolution of the area is favourable for the formation of stratiform deposits of uranium. The intensity of the orogenic deformation decreases progressively from west to east. The tendency to low dips favours the conditions of migration and precipitation of uranium. The majority of the geological formations of continental and deltaic origin, as well as igneous bodies of upper Palaeozoic and Tertiary age, have been selected as rocks of good geological uranium favourability, taking into consideration criteria found in other parts of the world.

This area presents similar geological conditions to the eastern side of the Andean Cordillera in Argentina where a number of uranium deposits have been located. (author)

  18. First attempt to assess the viability of bluefin tuna spawning events in offshore cages located in an a priori favourable larval habitat

    Patricia Reglero

    2013-10-01

    Full Text Available Most of the Atlantic bluefin tuna caught by the purse-seine fleet in the Mediterranean Sea are transferred alive into transport cages and towed to coastal facilities where they are fattened. This major fishery is targeting aggregations of reproductive bluefin tuna that continue spawning within the transport cages. Our study is the first attempt to assess the viability of the spawning events within transport cages placed offshore in a priori favourable locations for larval survival. The study was conducted in June 2010 in the Balearic Sea, a main spawning area for bluefin tuna in the Mediterranean. The location of two transport cages, one with wild and one with captive tuna, coincide with the situation of the chlorophyll front using satellite imagery as a proxy for the salinity front between resident surface waters and those of recent Atlantic origin. The results showed that bluefin tuna eggs were spawned almost every day within the two cages but few or no larvae were found. The expected larval densities estimated after applying mortality curves to the daily egg densities observed in the cages were higher than the sampled larval densities. The trajectories of the eggs after hatching estimated from a particle tracking model based on observed geostrophic currents and a drifter deployed adjacent to the cage suggest that larvae were likely to be caught close to the cages within the sampling dates. Spawning events in captive tuna in transport cages may hatch into larvae though they may experience higher mortality rates than expected in natural populations. The causes of the larval mortality are further discussed in the text. Such studies should be repeated in other spawning areas in the Mediterranean if spawning in cages located offshore in areas favourable a priori for larval survival is likely to be considered a management measurement to minimize the impact of purse-seine fishing on tuna.

  3. Oesophageal scintigraphy for the investigation of dysphagia: in and out of favour - and underused when available

    Stacey, Bernard; Patel, Praful [Department of Gastroenterology, Level D West, Mailpoint 47, Southampton General Hospital, Tremona Road, Southampton, Hants (United Kingdom)

    2002-09-01

    Oesophageal scintigraphy has been used for more than 25 years and allows quantifiable, safe, rapid, non-invasive and well-tolerated assessment of oesophageal transit time and function. As technology improves, more complex image analysis is becoming possible. Many studies have addressed its usefulness in assessing oesophageal dysmotility using manometry as the gold standard: this literature is reviewed with reference to both the sensitivity and the specificity of the test as well as its application and effectiveness in various disease states. The use of scintigraphy in oesophageal cancer is specifically addressed - including in co-existing dysmotility. (orig.)

  4. Psychosocial group rehabilitation for lonely older people: favourable processes and mediating factors of the intervention leading to alleviated loneliness.

    Savikko, Niina; Routasalo, Pirkko; Tilvis, Reijo; Pitkälä, Kaisu

    2010-03-01

    Loneliness among community-dwelling older people is a common problem, with serious health consequences. The favourable processes and mediating factors of a psychosocial group rehabilitation intervention in alleviating older people's loneliness were evaluated. Altogether, 117 lonely, home-dwelling individuals (aged ≥75 years) participated in a psychosocial group rehabilitation intervention. The content comprised (i) art and inspiring activities, (ii) group exercise and discussions or (iii) therapeutic writing and group therapy. The psychosocial group rehabilitation intervention was evaluated from the group leaders' diaries and by observing the groups. Experiences of loneliness and social participation were collected by postintervention questionnaires from the participants. Data were analysed using methodological triangulation. Doing things together and sharing experiences with their peers inspired lively discussions, created a feeling of togetherness and led to participants' empowerment and increased self-esteem. The intervention socially activated the participants, and their feelings of loneliness had been alleviated during the intervention. Several common favourable processes and mediating factors were identified in the psychosocial group rehabilitation intervention that led to alleviation of loneliness among older people. Relevance to clinical practice.  The psychosocial group rehabilitation intervention gives nurses an effective tool to support older people's psychosocial resources by activating them and alleviating their loneliness. © 2009 Blackwell Publishing Ltd.

  5. Sexual antagonism and meiotic drive cause stable linkage disequilibrium and favour reduced recombination on the X chromosome.

    Rydzewski, W T; Carioscia, S A; Liévano, G; Lynch, V D; Patten, M M

    2016-06-01

    Sexual antagonism and meiotic drive are sex-specific evolutionary forces with the potential to shape genomic architecture. Previous theory has found that pairing two sexually antagonistic loci or combining sexual antagonism with meiotic drive at linked autosomal loci augments genetic variation, produces stable linkage disequilibrium (LD) and favours reduced recombination. However, the influence of these two forces has not been examined on the X chromosome, which is thought to be enriched for sexual antagonism and meiotic drive. We investigate the evolution of the X chromosome under both sexual antagonism and meiotic drive with two models: in one, both loci experience sexual antagonism; in the other, we pair a meiotic drive locus with a sexually antagonistic locus. We find that LD arises between the two loci in both models, even when the two loci freely recombine in females and that driving haplotypes will be enriched for male-beneficial alleles, further skewing sex ratios in these populations. We introduce a new measure of LD, Dz', which accounts for population allele frequencies and is appropriate for instances where these are sex specific. Both models demonstrate that natural selection favours modifiers that reduce the recombination rate. These results inform observed patterns of congealment found on driving X chromosomes and have implications for patterns of natural variation and the evolution of recombination rates on the X chromosome. © 2016 European Society For Evolutionary Biology.

  6. Development of site selection criteria for radioactive waste disposal in view of favourable geological settings in Germany

    Baltes, B.; Brewitz, W.

    2001-01-01

    In Germany it is intended to dispose of all types of radioactive waste in deep geological formations. Since the government has doubts regarding the suitability of the Gorleben site, further sites in different host rock formations have to be investigated. This investigation process has to be carried out with respect to technical suitability and safety as well as to public acceptance. A Committee has been established whose mandate is to develop a comprehensible procedure for the selection of sites for radioactive waste disposal in Germany. The Committee developed an iterative procedure which provides, besides the increase of transparency, the necessary flexibility in dealing with assessment results. The method is governed by geo-scientific and social-scientific criteria that are presented in this paper. 7 steps have been identified in the procedure: 1) exclusion of areas with obviously unfavourable conditions, 2) identification of areas with favourable geological settings, 3) exclusion of areas for socio-scientific reasons, 4) identification of regions with favourable conditions and ranking of regions, 5) identification of sites for further identification, 6) above-ground site investigation and ranking of potentially suitable sites, and 7) identification of sites for suitability investigations. The first 3 steps give the remaining areas that meet the minimum requirements. The criteria of the first 3 steps are: extensive vertical movements, active disturbance zones, seismic activity and volcanic activity, as for the 4 last steps criteria are based on geo- and socio- scientific weighing, voluntariness and regional mediation.

  8. Changing Collective Social Norms in Favour of Reduced Harmful Use of Alcohol: A Review of Reviews.

    Anderson, Peter; Jané-Llopis, Eva; Hasan, Omer Syed Muhammad; Rehm, Jürgen

    2018-05-01

    Public sector bodies have called for policies and programmes to shift collective social norms in disfavour of the harmful use of alcohol. This article aims to identify and summarize the evidence and propose how policies and programmes to shift social norms could be implemented and evaluated. Review of reviews for all years to July 2017. Searches on OVID Medline, Healthstar, Embase, PsycINFO, AMED, Social Work Abstracts, CAB Abstracts, Mental Measurements Yearbook, Joanna Briggs Institute EBP, Health and Psychosocial Instruments, International Pharmaceutical Abstracts, International Political Science Abstracts, NASW Clinical Register and Epub Ahead of Print databases. All reviews, without language or date restrictions resulting from combining the terms ((review or literature review or review literature or data pooling or comparative study or systematic review or meta-analysis or pooled analysis) and (social norms or culture) and (alcohol drinking)). Two relevant reviews were identified. One review of community-based interventions found one study that demonstrated small changes in parental disapproval of under-age drinking. One review stressed that collective social norms about drinking are malleable and not uniform in any one country. Three factors are proposed to inform programmes: provide information about the consequences of the harmful use of alcohol, and their causes and distribution; act on groups, not individuals; and strengthen environmental laws, regulations and approaches. Purposeful policies and programmes could be implemented to change collective social norms in disfavour of the harmful use of alcohol; they should be evidence-based and fully evaluated for their impact.

  9. Clinical heterogeneity among people with high functioning autism spectrum conditions: evidence favouring a continuous severity gradient

    Woodbury-Smith Marc

    2008-02-01

    Full Text Available Abstract Background Autism Spectrum Conditions (ASCs are characterized by a high degree of clinical heterogeneity, but the extent to which this variation represents a severity gradient versus discrete phenotypes is unclear. This issue has complicated genetic studies seeking to investigate the genetic basis of the high hereditability observed clinically in those with an ASC. The aim of this study was to examine the possible clustering of symptoms associated with ASCs to determine whether the observed distribution of symptom type and severity supported either a severity or a symptom subgroup model to account for the phenotypic variation observed within the ASCs. Methods We investigated the responses of a group of adults with higher functioning ASCs on the fifty clinical features examined in the Autism Spectrum Quotient, a screening questionnaire used in the diagnosis of higher functioning ASCs. In contrast to previous studies we have used this instrument with no a priori assumptions about any underlying factor structure of constituent items. The responses obtained were analyzed using complete linkage hierarchical cluster analysis. For the members of each cluster identified the mean score on each Autism Spectrum Quotient question was calculated. Results Autism Spectrum Quotient responses from a total of 333 individuals between the ages of 16.6 and 78.0 years were entered into the hierarchical cluster analysis. The four cluster solution was the one that generated the largest number of clusters that did not also include very small cluster sizes, defined as a membership comprising 10 individuals or fewer. Examination of these clusters demonstrated that they varied in total Autism Spectrum Quotient but that the profiles across the symptoms comprising the Autism Spectrum Quotient did not differ independently of this severity factor. Conclusion These results are consistent with a unitary spectrum model, suggesting that the clinical heterogeneity observed

    2009-01-01

    The interaction between hexavalent chromium Cr(VI), as K 2 CrO 4 , and standard humic acids (HAs) in bulk solution was studied using three complementary analytical methods: UV-Visible spectroscopy, X-ray absorption spectroscopy and differential pulse stripping voltammetry. The observed UV-Vis and X-ray absorption spectra showed that, under our experimental conditions, HAs did not induce reduction of Cr(VI) to its trivalent chemical form. The interaction between Cr(VI) and HAs has rather led to the formation of Cr(VI)-HAs micelles via supramolecular chemical processes. The reported results could contribute towards explaining the relative persistence of ecotoxic hexavalent chromium in soils. - Humic acids (HAs) did not induce reduction of Cr(VI) to its trivalent chemical form, as the interaction between Cr(VI) and HAs rather led to the formation of Cr(VI)-HAs micelles via supramolecular chemical processes.

    2009-01-01

    There is a lot of excitement about the potential use of multipotent neural stem cells for the treatment of neurodegenerative diseases. However, the strategy is compromised by the general loss of multipotency and ability to generate neurons after long-term in vitro propagation. In the present study......, human embryonic (5 weeks post-conception) ventral mesencephalic (VM) precursor cells were propagated as neural tissue-spheres (NTS) in epidermal growth factor (EGF; 20 ng/ml) and fibroblast growth factor 2 (FGF2; 20 ng/ml). After more than 325 days, the NTS were transferred to media containing either...... EGF+FGF2, EGF+FGF2+heparin or leukemia inhibitory factor (LIF; 10 ng/ml)+FGF2+heparin. Cultures were subsequently propagated for more than 180 days with NTS analyzed at various time-points. Our data show for the first time that human VM neural precursor cells can be long-term propagated as NTS...

    Duchenne and Becker muscular dystrophy (DMD/BMD) are both caused by mutations in the DMD gene. Out-of-frame mutations in DMD lead to absence of the dystrophin protein, while in-frame BMD mutations cause production of internally deleted dystrophin. Clinically, patients with DMD loose ambulance around the age of 12, need ventilatory support at their late teens and die in their third or fourth decade due to pulmonary or cardiac failure. BMD has a more variable disease course. The disease course of patients with BMD with specific mutations could be very informative to predict the outcome of the exon-skipping therapy, aiming to restore the reading-frame in patients with DMD. Patients with BMD with a mutation equalling a DMD mutation after successful exon skipping were selected from the Dutch Dystrophinopathy Database. Information about disease course was gathered through a standardised questionnaire. Cardiac data were collected from medical correspondence and a previous study on cardiac function in BMD. Forty-eight patients were included, representing 11 different mutations. Median age of patients was 43 years (range 6-67). Nine patients were wheelchair users (26-56 years). Dilated cardiomyopathy was present in 7/36 patients. Only one patient used ventilatory support. Three patients had died at the age of 45, 50 and 76 years, respectively. This study provides mutation specific data on the course of disease in patients with BMD. It shows that the disease course of patients with BMD, with a mutation equalling a 'skipped' DMD mutation is relatively mild. This finding strongly supports the potential benefit of exon skipping in patients with DMD.

  16. The School System and New Media – Reasons in Favour of Integration

    M. Marković

    2017-06-01

    Full Text Available In the education system reform which is currently underway in Serbia and in most countries of the region, considerable attention has been paid to modern media technologies. Although a whole decade has passed since the initiation of the reform there have been no significant developments regarding the school system computerisation, which resulted in raising the issue of integration and seeking valid arguments which indicate the key role of new media in the re-structuring of the school system. In that context, the basic goal of this paper is an analysis of primary research studies which suggest the reasons for the inte-gration of new media into the school system in order to set out the reform guidelines regarding the application of information and communication tech-nologies in formal education. The results of the analysis attest to a large num-ber of compelling reasons for implementing modern media technologies into the system of educational institutions. Among them one should distinguish the general reasons which deal with improving the quality of and bridging the gap between formal and informal education. The selected research studies state objective reasons such as rationality and cost-effectiveness, as well as peda-gogical reasons relating to the learning context innovation, presence of new knowledge sources provided by Internet resources, changes in the process of learning instigated by the development of e-learning and a higher motivation of the participants in the process of education. In the conclusion of this re-search the authors emphasise the necessity of integrating media technologies into the school system for the purposes of creating a modern coherent system founded on networking, communication and exchange.

  17. Computerised Provider Order Entry Adoption Rates Favourably Impact Length of Stay

    Richard Schreiber

    2016-04-01

    Full Text Available Background Research regarding return on investment for electronic health records (EHRs is sparse. Objective To extend previously established research and examine rigorously whether increasing the adoption of computer-based provider/prescriber order entry (CPOE leads to a decrease in length of stay (LOS, and to demonstrate that the two are inversely and bidirectionally proportional even while other efforts to decrease LOS are in place. Method The study assessed CPOE, LOS and case mix index (CMI data in a community hospital in the United States, using a mature and nearly fully deployed vendor product EHR. CPOE rates and LOS over 7 years were determined on a per-patient, per-visit and per-discipline basis and compared with concomitant CMI data. Results An inverse relationship of CPOE to LOS was correlated for 13 disciplines out of 19, and organisation wide for all disciplines combined during the first 5 years of study. During the subsequent 2 years, both CPOE and LOS plateaued, except in eight disciplines where CPOE rates at first declined and LOS concurrently rose slightly, and then returned to the baseline plateau levels. CMI increased during the entire period of evaluation. An inflection point at approximately 60% CPOE adoption predicted the greatest improvement in lowering of LOS. Conclusions Rising and falling rates of CPOE correlated with reductions and rises in LOS, respectively. CPOE appeared statistically to be an independent factor in affecting LOS, over and above other efforts to shorten LOS, thus contributing to lower costs and improved efficiency outcomes as measured by LOS, even as CMI rises.

    The current study aimed to assess Uruguayan consumers' accounts of their own need to change their dietary patterns, their intended changes and the barriers related to doing so, and to compare the intentions and barriers with the recommendations of the national dietary guidelines. An online survey with 2381 Uruguayan employed adults, aged between 18 and 65 years, 65 % females, was conducted. Participants had to answer two open-ended questions related to changes they could make in the foods they eat and/or the way in which they eat to improve the quality of their diet and the reasons why they had not implemented those changes yet. Content analysis using inductive coding by two researchers was used to analyse the responses. Consumers mainly intended to change consumption of types of foods, particularly eating more fruits, vegetables and legumes and consuming less flour, but also intended to alter their eating patterns. Lack of time and the fact that healthy foods are perceived as being more expensive than unhealthy foods were major barriers to behaviour change. Some of the recommendations of the dietary guidelines, particularly those related to enjoying cooking and meals and engaging in it as a social activity, were not represented in consumer accounts. Accompanying policies to the dietary guidelines need to underline the importance of changes in dietary patterns, including greater enjoyment and sharing food preparation and meals in the company with others, address misconceptions about flour, and provide concrete, consumer-derived recommendations on how to enact the guidelines.

    Aim: To assess the magnetic resonance imaging (MRI) features and natural history of intramedullary tumours in patients with neurofibromatosis type 2 (NF2). Materials and methods: Eleven NF2 patients with intramedullary spinal cord tumours were identified from the database of the multidisciplinary NF2 clinic. All the imaging studies of these patients were individually reviewed by two neuroradiologists to evaluate the size, number, location, imaging characteristics, and interval growth of the intramedullary tumours. Results: Two of the 11 patients had lesions that required surgery. Both these lesions were in the cervical region, and extended over three and five segments respectively. Nine patients with a mean imaging follow-up period of 77 months had lesions that remained stable, apart from the development of small peritumoral cysts in three. The lesions were well circumscribed, often multiple, usually less than 1 cm in diameter, and were most frequently found in the cervical cord. Conclusion: The majority of intramedullary tumours in NF2 patients are very slow growing and share certain MRI features that differ from those of progressive or symptomatic lesions.

  20. Review for carrageenan-based pharmaceutical biomaterials: favourable physical features versus adverse biological effects.

    Liu, Jingjing; Zhan, Xiudan; Wan, Jianbo; Wang, Yitao; Wang, Chunming

    2015-05-05

    Carrageenan (CRG) is a family of natural polysaccharides derived from seaweeds and has widely been used as food additives. In the past decade, owing to its attractive physicochemical properties, CRG has been developed into versatile biomaterials vehicles for drug delivery. Nevertheless, studies also emerged to reveal its adverse effects on the biological system. In this review, we critically appraise the latest literature (two thirds since 2008) on the development of CRG-based pharmaceutical vehicles and the perspective of using CRG for broader biomedical applications. We focus on how current strategies exploit the unique gelling mechanisms, strong water absorption and abundant functional groups of the three major CRG varieties. Notably, CRG-based matrices are demonstrated to increase drug loading and drug solubility, enabling release of orally administrated drugs in zero-order or in a significantly prolonged period. Other amazing features, such as pH-sensitivity and adhesive property, of CRG-based formulations are also introduced. Finally, we discuss the adverse influence of CRG on the human body and then suggest some future directions for the development of CRG-based biomaterials for broader applications in biomedicine.

  1. Autologous adipocyte derived stem cells favour healing in a minipig model of cutaneous radiation syndrome.

    Fabien Forcheron

    Full Text Available Cutaneous radiation syndrome (CRS is the delayed consequence of localized skin exposure to high doses of ionizing radiation. Here we examined for the first time in a large animal model the therapeutic potential of autologous adipose tissue-derived stroma cells (ASCs. For experiments, Göttingen minipigs were locally gamma irradiated using a (60Co source at the dose of 50 Gy and grafted (n = 5 or not (n = 8. ASCs were cultured in MEM-alpha with 10% fetal calf serum and basic fibroblast growth factor (2 ng.mL(-1 and post irradiation were intradermally injected on days 25, 46, 67 and finally between days 95 and 115 (50 × 10(6 ASCs each time into the exposed area. All controls exhibited a clinical evolution with final necrosis (day 91. In grafted pigs an ultimate wound healing was observed in four out of five grafted animals (day 130 +/- 28. Immunohistological analysis of cytokeratin expression showed a complete epidermis recovery. Grafted ASCs accumulated at the dermis/subcutis barrier in which they attracted numerous immune cells, and even an increased vasculature in one pig. Globally this study suggests that local injection of ASCs may represent a useful strategy to mitigate CRS.

  2. Foreign direct investment in the health care sector and most-favoured locations in developing countries.

    Outreville, J François

    2007-12-01

    Given the growing importance of the health care sector and the significant development of trade in health services, foreign direct investment (FDI) in this sector has gathered momentum with the General Agreement on Trade in Services. Despite extensive case based research and publications in recent years on health care markets and the rise of private sectors, it is surprisingly difficult to find evidence on the relative importance of the largest multinational corporations (MNCs) operating in the health care sector. The objective of the paper is to identify some of the determinants of foreign investment of the largest MNCs operating in this industry. The list of the largest MNCs has been compiled using company websites and data is available for 41 developing economies for which at least two MNCs have an office (branch and/or affiliate). The results of this study have some important implications. They indicate that location-specific advantages of host countries, including good governance, do provide an explication of the internationalization of firms in some developing countries rather than others.

  3. Fortune favours the brave: Movement responses shape demographic dynamics in strongly competing populations.

    Potts, Jonathan R; Petrovskii, Sergei V

    2017-05-07

    Animal movement is a key mechanism for shaping population dynamics. The effect of interactions between competing animals on a population's survival has been studied for many decades. However, interactions also affect an animal's subsequent movement decisions. Despite this, the indirect effect of these decisions on animal survival is much less well-understood. Here, we incorporate movement responses to foreign animals into a model of two competing populations, where inter-specific competition is greater than intra-specific competition. When movement is diffusive, the travelling wave moves from the stronger population to the weaker. However, by incorporating behaviourally induced directed movement towards the stronger population, the weaker one can slow the travelling wave down, even reversing its direction. Hence movement responses can switch the predictions of traditional mechanistic models. Furthermore, when environmental heterogeneity is combined with aggressive movement strategies, it is possible for spatially segregated co-existence to emerge. In this situation, the spatial patterns of the competing populations have the unusual feature that they are slightly out-of-phase with the environmental patterns. Finally, incorporating dynamic movement responses can also enable stable co-existence in a homogeneous environment, giving a new mechanism for spatially segregated co-existence.

  4. Absence of p53 in Clara cells favours multinucleation and loss of cell cycle arrest

    Clarke Alan R

    2002-11-01

    Full Text Available Abstract Background The p53 oncosuppressor protein is a critical mediator of the response to injury in mammalian cells and is mutationally inactivated in the majority of lung malignancies. In this analysis, the effects of p53-deficiency were investigated in short-term primary cultures of murine bronchiolar Clara cells. Clara cells, isolated from gene-targeted p53-deficient mice, were compared to cells derived from wild type littermates. Results p53 null cultures displayed abnormal morphology; specifically, a high incidence of multinucleation, which increased with time in culture. Multinucleated cells were proficient in S phase DNA synthesis, as determined by BrdU incorporation. However, multinucleation did not reflect altered rates of S phase synthesis, which were similar between wild type and p53-/- cultures. Nucleation defects in p53-/- Clara cells associated with increased centrosome number, as determined by confocal microscopy of pericentrin-stained cultures, and may highlight a novel role of p53 in preserving genomic integrity in lung epithelial cells. Effects of p53-deficiency were also studied following exposure to DNA damage. A p53-dependent reduction in the BrdU index was observed in Clara cells following ionizing radiation. The reduction in BrdU index in wild type cells displayed serum-dependency, and occurred only in the absence of serum. Taken together, these findings demonstrate that in murine primary Clara cell culture, cell cycle arrest is a p53-mediated response to DNA damage, and that extracellular factors, such as serum, influence this response. Conclusion These findings highlight functions of wild type p53 protein in bipolar spindle formation, centrosome regulation, and growth control in bronchiolar Clara cells.

  5. Favourable changes in economic well-being and self-rated health among the elderly

    Brenes-Camacho, Gilbert

    2011-01-01

    Adverse economic shocks exert an influence on health perceptions, but little is known about the effect of sudden positive changes in a person’s financial situation on self-rated health, particularly among low income people. This paper explores the association between an increase in the amount of non-contribution pensions, public cash transfers given to Costa Rican elderly of low socio-economic status (SES) and changes in self-rated health over time. The analysis is based on data from CRELES, the “Costa Rican Study on Longevity and Healthy Aging”, which is based on a probabilistic sample of people born in 1945 or earlier, and living in Costa Rica by 2002. The fieldwork for the first and second waves of CRELES was conducted from 2004 to 2006, and from 2006 to 2008, respectively. The Costa Rican Government raised the amount of the non-contribution pension for the poor 100% before July 2007, and an additional 100% after that date. Due to the CRELES fieldwork schedule, the data have a natural quasi-experimental design, given that approximately half of CRELES respondents were interviewed before July 2007, independently of their status in receiving the public cash transfers. Using random effects ordered probit regression models, we find that people who experienced such increase report a greater improvement in self-rated health between waves than those who experienced a smaller increase and than the rest of the interviewees. Results suggest that increases in income may lead to a greater improvement in self-rated health. PMID:21440352

    Full Text Available This paper reports on research based on an experimental questionnaire designed using the logic and the basic structure of the Moral Judgment Test (MJT by Lind (1982. The study aims at understanding how respondents' acceptance of political arguments may have contributed to the lack of international support for the Iraq war and/or to the failure to prevent a preemptive attack. It examines factors, which respondents may have relied on in their acceptance of the arguments. The instrument consisted of three components: (1 A brief vignette on the declared beginning (March 19, 2003 and ending (May 1, 2003 of major operations in Iraq. (2 Respondents' own agreement with the need for the war. (3 Twelve arguments from political speeches: Six arguments by Bush and Blair "in favor of" (pro, and six arguments by Chirac and Schroeder "against" (con the need for the Iraq war. We scored each argument using Kohlberg's (1984 stage theory and Commons' Hierarchical Complexity Scoring System (HCSS (Commons et al., 2004, which identifies hierarchical features in the structure. Using Kempf's (2003 Cognitive Escalation and De-Escalation Model (CEDM we scored each argument sentence for details. Our sample consists of (N = 397 respondents of which were 56.4% women, 24.2% men, and 19.4% did not specify. The largest groups consisted of 71% Germans, 37.2% Catholics, 74.3% between the ages of 18-20 with high school education. Another group consisted of 8.6% Americans with a broader spectrum in age and higher educational level. Using 7 point Likert scales, respondents rated whether they would have rejected or accepted the main point of each argument, whether the main point of the argument seemed illusory or realistic, and whether the emotion evoked by the argument was destructive or constructive. The analysis of the data aimed at determining which within subject and between subject design factors were relevant in predicting respondents' acceptance of arguments and the

  7. From favours to entitlements: community voice and action and health service quality in Zambia.

    Schaaf, Marta; Topp, Stephanie M; Ngulube, Moses

    2017-07-01

    Social accountability is increasingly invoked as a way of improving health services. This article presents a theory-driven qualitative study of the context, mechanisms and outcomes of a social accountability program, Citizen Voice and Action (CVA), implemented by World Vision (WV) in Zambia. Primary data were collected between November 2013 and January 2014. It included in-depth interviews and focus group discussions with program stakeholders. Secondary data were used iteratively-to inform the process for primary data collection, to guide primary data analysis and to contextualize findings from the primary data. CVA positively impacted the state, society, state-society relations and development coordination at the local level. Specifically, sustained improvements in some aspects of health system responsiveness, empowered citizens, the improved provision of public goods (health services) and increased consensus on development issues appeared to flow from CVA. The central challenge described by interviewees and FGD participants was the inability of CVA to address problems that required central level input. The mechanisms that generated these outcomes included productive state-society communication, enhanced trust, and state-society co-production of priorities and the provision of services. These mechanisms were activated in the context of existing structures for state-society interaction, willing political leaders, buy-in by traditional leaders, and WV's strong reputation and access to resources. Prospective observational research in multiple contexts would shed more light on the context, mechanisms and outcomes of CVA programs. In addition to findings that are intuitive and well supported in the literature we identified new areas that are promising areas for future research. These include (1) the context of organizational reputation by the organization(s) spearheading social accountability efforts; (2) the potential relationship between social accountability efforts

  9. Evolutionary conservation advice for despotic populations: habitat heterogeneity favours conflict and reduces productivity in Seychelles magpie robins.

    López-Sepulcre, Andrés; Kokko, Hanna; Norris, Ken

    2010-11-22

    Individual preferences for good habitat are often thought to have a beneficial stabilizing effect for populations. However, if individuals preferentially compete for better-quality territories, these may become hotspots of conflict. We show that, in an endangered species, this process decreases the productivity of favoured territories to the extent that differences in productivity between territories disappear. Unlike predictions from current demographic theory on site-dependent population regulation (ideal despotic distribution), we show that population productivity is reduced if resources are distributed unevenly in space. Competition for high-quality habitat can thus have detrimental consequences for populations even though it benefits individuals. Manipulating conflict (e.g. by reducing variation in habitat quality) can therefore prove an effective conservation measure in species with strong social or territorial conflict.

  10. Uranium favourability and evaluation in Mongolia (phase II), recent events in uranium resources and production in Mongolia

    Batbold, T.

    2001-01-01

    Uranium exploration in Mongolia covered a period of over 5 decades. The main results of these activities were the discoveries of 6 uranium deposits and about 100 occurrences as well as numerous favourable indications. Sizable resources are found mainly in deposits of the sandstone, volcanic and alkaline intrusive types. Of these, the first two are considered to be of economic importance. Uranium production in Mongolia started in 1989 with the exploitation of volcanic type uranium deposits of the Mongol-Priargun metallogenic province, known as the Dornot Mine. Due to political and economic changes in the country and neighbouring areas of the Russian Federation, this uranium production was terminated in 1995. A new plan to restart production at the Mardai-gol deposits as a joint venture between Mongolia, the Russian Federation and a US company is being considered. (author)

  13. Depigmented-polymerised allergoids favour regulatory over effector T cells: enhancement by 1α, 25-dihydroxyvitamin D3.

    2014-05-29

    Allergen immunotherapy (SIT) is the only treatment for allergic disease capable of modifying disease long term. To reduce the risk of anaphylaxis from SIT, allergen-extracts have been modified by polymerisation with glutaraldehyde to reduce IgE binding. It is suggested that these allergoid extracts also have reduced T cell activity, which could compromise clinical efficacy. Effective SIT is thought to act through regulatory T cells (Tregs) rather than activation of effector T cells. There is no published data on the activity of modified extracts on Tregs. We compared the capacity of modified (depigmented-polymerised) versus unmodified (native) allergen extracts of grass pollen and house dust mite to stimulate proliferation/cytokine production and to modulate Treg/effector T cell frequency in cultures of peripheral blood mononuclear cells (PBMC), from volunteers sensitised to both allergens in vitro. Depigmented-polymerised allergen extracts stimulated less proliferation of PBMC, and reduced effector cell numbers after 7 days in culture than did native extracts. However, the frequency of Foxp3+ Tregs in cultures were similar to those seen with native extract so that ratios of regulatory to effector T cells were significantly increased in cultures stimulated with depigmented-polymerised extracts. Addition of 1α, 25-dihydroxyvitamin D3 further favoured Treg, and reduced effector cytokine production, but not interleukin-10. Depigmented-polymerised allergen extracts appear to favour Treg expansion over activation of effector T cells and this may relate to their demonstrated efficacy and safety in SIT. 1α, 25-dihydroxyvitamin D3 further reduces effector T cell activation by allergen extracts and may be a useful adjuvant for SIT.

  14. Cost-minimization analysis favours intravenous ferric carboxymaltose over ferric sucrose for the ambulatory treatment of severe iron deficiency.

    Xavier Calvet

    Full Text Available OBJECTIVE: Intravenous iron is widely used to treat iron deficiency in day-care units. Ferric carboxymaltose (FCM allows administration of larger iron doses than iron sucrose (IS in each infusion (1000 mg vs. 200 mg. As FCM reduces the number of infusions required but is more expensive, we performed a cost-minimization analysis to compare the cost impact of the two drugs. MATERIALS AND METHODS: The number of infusions and the iron dose of 111 consecutive patients who received intravenous iron at a gastrointestinal diseases day-care unit from 8/2007 to 7/2008 were retrospectively obtained. Costs of intravenous iron drugs were obtained from the Spanish regulatory agencies. The accounting department of the Hospital determined hospital direct and indirect costs for outpatient iron infusion. Non-hospital direct costs were calculated on the basis of patient interviews. In the pharmacoeconomic model, base case mean costs per patient were calculated for administering 1000 mg of iron per infusion using FCM or 200 mg using IS. Sensitivity analysis and Monte Carlo simulation were performed. RESULTS: Under baseline assumptions, the estimated cost of iron infusion per patient and year was €304 for IS and €274 for FCM, a difference of €30 in favour of FCM. Adding non-hospital direct costs to the model increased the difference to €67 (€354 for IS vs. €287 for FCM. A Monte Carlo simulation taking into account non-hospital direct costs favoured the use of FCM in 97% of simulations. CONCLUSION: In this pharmacoeconomic analysis, FCM infusion reduced the costs of iron infusion at a gastrointestinal day-care unit.

    Most HIV prevention strategies assume beneficiaries can act on their prevention decisions. But some people are unable to do so. They are 'choice-disabled'. Economic and educational interventions can reduce sexual violence, but there is less evidence that they can reduce HIV. There is little research on complex interventions in HIV prevention, yet all countries in southern Africa implement combination prevention programmes. The primary objective is to reduce HIV infections among women aged 15 to 29 years. Secondary objectives are reduction in gender violence and improvement in HIV-related knowledge, attitudes and practices among youth aged 15 to 29 years.A random sample of 77 census enumeration areas in three countries (Botswana, Namibia and Swaziland) was allocated randomly to three interventions, alone or in combination, in a factorial design stratified by country, HIV rates (above or below average for country), and urban/rural location. A baseline survey of youth aged 15 to 29 years provided cluster specific rates of HIV. All clusters continue existing prevention efforts and have a baseline and follow-up survey. Cluster is the unit of allocation, intervention and analysis, using generalised estimating equations, on an intention-to-treat basis.One intervention discusses evidence about choice disability with local HIV prevention services, to help them to serve the choice-disabled. Another discusses an eight-episode audio-docudrama with community groups, of all ages and both sexes, to generate endogenous strategies to reduce gender violence and develop an enabling environment. A third supports groups of women aged 18 to 25 years to build self-esteem and life skills and to set up small enterprises to generate income.A survey in all clusters after 3 years will measure outcomes, with interviewers unaware of group assignment of the clusters. The primary outcome is HIV infection in women aged 15 to 29 years. Secondary outcomes in youth aged 15 to 29 years are gender violence and protective knowledge, attitudes, subjective norms, intention to change, agency, discussion of prevention and practices related to HIV and gender violence.

    Full Text Available A mega-event is a replicant: local copy of a global model. The European Capitals of Culture (ECC is an annual mega-event, currently usually held in two European cities. This paper argues it has three particular dimensions, recognisable from the European Union’s policy. First designed to articulate a European identity, it has been a mover for local urban transformation and city-branding, and later participation. The policy projects Europe as “family of cultures”, which suggests attention for a particular ECC year, when the old Saxon fortress town of Luxembourg hosted the title together with the former Saxon fortress town Sibiu of Romania, which joined the European Union only the same year: 2007.

    Factors, affecting mineralization processes are considered. Characteristic features of uranium-bearing provinces are as follows: the presence of crust of continental type; deep-seated tectonic structures-rises and saggings, roofs, gneiss domes, rift zones and transform fractures; specialization for uranium of sedimentary and magmatic formations; the presence of manifestation regions of deep thermal and gaseous flow, etc. In uranium-bearing provinces territories favourable for the manifestation of different types of uranium mineralization: metamorphogenetic, polygenetic and exogenetic ones, are singled out. Different epochs of uranium ore formation are established. In sedimentary masses tectonic regime and climate are of special importance, and for epigenetic deposits, formed with an aid of underground waters-hydrogeological conditions. In the limits of the main structural elements of the Earth crust and geotectonic structures of higher orders the following types of sedimentary and volcanic formations can be singled out: 1-formations with exogenous uranium mineralization; 2-formations, accumulated in the epochs of epigenous ore formation; 3-formations fav ourable for epigenous uranium deposit formation; 4-formations unfavourable for the formation and localization of uranium mineralization

  1. Post-fire environments are favourable for plant functioning of seeder and resprouter Mediterranean shrubs, even under drought.

    Parra, Antonio; Moreno, José M

    2017-05-01

    Understanding how drought affects seeder and resprouter plants during post-fire regeneration is important for the anticipation of Mediterranean vegetation vulnerability in a context of increasing drought and fire caused by climate change. A Mediterranean shrubland was subjected to various drought treatments (including 45% rainfall reduction, 7 months drought yr -1 ), before and after experimental burning, by means of a rainout-shelter system with an irrigation facility. Predawn shoot water potential (Ψ pd ), relative growth rate (RGR), specific leaf area (SLA) and bulk leaf carbon isotopic composition (δ 13 C) were monitored in the main woody species during the first 3 yr after fire. Cistus ladanifer seedlings showed higher Ψ pd , RGR and SLA, and lower δ 13 C, than unburned plants during the first two post-fire years. Seedlings under drought maintained relatively high Ψ pd , but suffered a decrease in Ψ pd and RGR, and an increase in δ 13 C, relative to control treatments. Erica arborea, E. scoparia and Phillyrea angustifolia resprouts had higher Ψ pd and RGR than unburned plants during the first post-fire year. Resprouters were largely unaffected by drought. Overall, despite marked differences between the two functional groups, post-fire environments were favourable for plant functioning of both seeder and resprouter shrubs, even under the most severe drought conditions implemented. © 2017 The Authors.

  2. Genetic favouring of pheomelanin-based pigmentation limits physiological benefits of coloniality in lesser kestrels Falco naumanni.

    Pheomelanin contributes to the pigmentation phenotype of animals by producing orange and light brown colours in the integument. However, pheomelanin synthesis in melanocytes requires consumption of glutathione (GSH), the most important intracellular antioxidant. Therefore, a genetic control favouring the production of large amounts of pheomelanin for pigmentation may lead to physiological costs under environmental conditions that promote oxidative stress. We investigated this possibility in the context of breeding coloniality, a reproductive strategy that may affect oxidative stress. We found in lesser kestrel Falco naumanni nestlings that the GSH:GSSG ratio, which decreases with systemic oxidative stress, increased with the size of the colony where they were reared, but the expression in feather melanocytes of five genes involved in pheomelanin synthesis (Slc7a11, Slc45a2, CTNS, MC1R and AGRP) did not vary with colony size. The antioxidant capacity (TEAC) of lesser kestrel nestlings also increased with colony size, but in a manner that depended on Slc7a11 expression and not on the expression of the other genes. Thus, antioxidant capacity increased with colony size only in nestlings least expressing Slc7a11, a gene with a known role in mediating cysteine (a constituent amino acid of GSH) consumption for pheomelanin production. The main predictor of the intensity of pheomelanin-based feather colour was Slc45a2 expression followed in importance by Slc7a11 expression, hence suggesting that the genetic regulation of the pigmentation phenotype mediated by Slc7a11 and a lack of epigenetic lability in this gene limits birds from benefiting from the physiological benefits of coloniality. © 2017 John Wiley & Sons Ltd.

  3. FoxA4 favours notochord formation by inhibiting contiguous mesodermal fates and restricts anterior neural development in Xenopus embryos.

    Sabrina Murgan

    Full Text Available In vertebrates, the embryonic dorsal midline is a crucial signalling centre that patterns the surrounding tissues during development. Members of the FoxA subfamily of transcription factors are expressed in the structures that compose this centre. Foxa2 is essential for dorsal midline development in mammals, since knock-out mouse embryos lack a definitive node, notochord and floor plate. The related gene foxA4 is only present in amphibians. Expression begins in the blastula -chordin and -noggin expressing centre (BCNE and is later restricted to the dorsal midline derivatives of the Spemann's organiser. It was suggested that the early functions of mammalian foxa2 are carried out by foxA4 in frogs, but functional experiments were needed to test this hypothesis. Here, we show that some important dorsal midline functions of mammalian foxa2 are exerted by foxA4 in Xenopus. We provide new evidence that the latter prevents the respecification of dorsal midline precursors towards contiguous fates, inhibiting prechordal and paraxial mesoderm development in favour of the notochord. In addition, we show that foxA4 is required for the correct regionalisation and maintenance of the central nervous system. FoxA4 participates in constraining the prospective rostral forebrain territory during neural specification and is necessary for the correct segregation of the most anterior ectodermal derivatives, such as the cement gland and the pituitary anlagen. Moreover, the early expression of foxA4 in the BCNE (which contains precursors of the whole forebrain and most of the midbrain and hindbrain is directly required to restrict anterior neural development.

  6. Morphometry, ultrastructure, myosin isoforms, and metabolic capacities of the "mini muscles" favoured by selection for high activity in house mice.

    Guderley, Helga; Houle-Leroy, Philippe; Diffee, Gary M; Camp, Dana M; Garland, Theodore

    2006-07-01

    Prolonged selective breeding of mice (Mus musculus) for high levels of voluntary wheel running has favoured an unusual phenotype ("mini muscles"), apparently caused by a single Mendelian recessive allele, in which most hind-limb muscles are markedly reduced in mass, but have increased mass-specific activities of mitochondrial enzymes. We examined whether these changes reflect changes in fibre size, number or ultrastructure in normal and "mini-muscle" mice within the two (of four) selectively bred lines (lab designations L3 and L6) that exhibit the phenotype at generations 26 and 27. In both lines, the gastrocnemius and plantaris muscles are smaller in mass (by >50% and 20%, respectively) in affected individuals. The mass-specific activities of mitochondrial enzymes in the gastrocnemius and plantaris muscles were increased in the mini phenotype in both lines, with stronger effects in the gastrocnemius muscle. In the gastrocnemius, the % myosin heavy chain (MHC) IIb was reduced by 50% in L3 and by 30% in L6, whereas the % MHC IIa and I were higher, particularly in L3. Fibre number in the plantaris muscle did not significantly differ between mini and normal muscles, although muscle mass was a significant positive correlate of fibre number. Small fibres were more abundant in mini than normal muscles in L3. Mitochondrial volume density was significantly higher in mini than normal muscle fibres in L3, but not in L6. Microscopy revealed a surprising attribute of the mini muscles: an abundance of small, minimally differentiated, myofibril-containing cells positioned in a disorderly fashion, particularly in the surface layer. We hypothesise that these unusual cells may be satellite cells or type IIb fibres that did not complete their differentiation. Together, these observations suggest that mice with the mini phenotype have reduced numbers of type IIb fibres in many of their hind-limb muscles, leading to a decrease in mass and an increase in mass-specific aerobic capacity

    Objectives This study aimed to assess the prevalence of dementia and cognitive complaints in a cross-sectional sample of Luxembourg seniors, and to discuss the results in the societal context of high cognitive reserve resulting from multilingualism. Methods A population sample of 1,377 people representative of Luxembourg residents aged over 64 years was initially identified via the national social insurance register. There were three different levels of contribution: full participation in the study, partial participation, and non-participation. We examined the profiles of these three different samples so that we could infer the prevalence estimates in the Luxembourgish senior population as a whole using the prevalence estimates obtained in this study. Results After careful attention to the potential bias and of the possibility of underestimation, we considered the obtained prevalence estimates of 3.8% for dementia (with corresponding 95% confidence limits (CL) of 2.8% and 4.8%) and 26.1% for cognitive complaints (CL = [17.8–34.3]) as trustworthy. Conclusion Based on these findings, we postulate that high cognitive reserve may result in surprisingly low prevalence estimates of cognitive complaints and dementia in adults over the age of 64 years, which thereby corroborates the longer disability-free life expectancy observed in the Luxembourg population. To the best of our knowledge, this study is the first to report such Luxembourgish public health data. PMID:26390288

    Full Text Available Abstract Background In 2009, Santa Isabel Province in the Solomon Islands embarked on a malaria elimination programme. However, very little is known in the Province about the anopheline fauna, which species are vectors, their bionomics and how they may respond to intensified intervention measures. The purpose of this study was to provide baseline data on the malaria vectors and to ascertain the possibility of successfully eliminating malaria using the existing conventional vector control measures, such as indoor residual spraying (IRS and long-lasting insecticidal nets (LLIN. Methods Entomological surveys were undertaken during October 2009. To determine species composition and distribution larval surveys were conducted across on the whole island. For malaria transmission studies, adult anophelines were sampled using human landing catches from two villages - one coastal and one inland. Results Five Anopheles species were found on Santa Isabel: Anopheles farauti, Anopheles hinesorum, Anopheles lungae, Anopheles solomonis, and Anopheles nataliae. Anopheles hinesorum was the most widespread species. Anopheles farauti was abundant, but found only on the coast. Anopheles punctulatus and Anopheles koliensis were not found. Anopheles farauti was the only species found biting in the coastal village, it was incriminated as a vector in this study; it fed early in the night but equally so indoors and outdoors, and had a low survival rate. Anopheles solomonis was the main species biting humans in the inland village, it was extremely exophagic, with low survival rates, and readily fed on pigs. Conclusion The disappearance of the two major vectors, An. punctulatus and An. koliensis, from Santa Isabel and the predominance of An. hinesorum, a non-vector species may facilitate malaria elimination measures. Anopheles farauti was identified as the main coastal vector with An. solomonis as a possible inland vector. The behaviour of An. solomonis is novel as it has

  9. The most-favoured-nation clause in tax treaties: tool for potential reduction of withholding income tax applicable to Chile and Canada

    2013-07-01

    Full Text Available Tax treaties to avoid the double taxation signed by a country have consequences for the future, but they can also modify the terms of treaties that are already in force, in case these contain most-favoured-nation clauses. In this line, taxpayers and companies, particularly, as well as the Tax Administration must be alert, regarding topotential modifications of the terms of the Peruvian tax treaties already in force; mainly about the withholding tax rate applied to royalties in the Convention subscribed with Chile and the withholding tax rates applied to dividends, interests and royalties in the Convention subscribed with Canada, taking into account that both of the mentioned tax treaties contain most-favoured-nation clauses for those kind of income. The Ministry of Economy, as the entity in charge of negotiations of the bilateral conventions, according to Law Decree 25883, has the responsibility of negotiating future treaties with full knowledge that the terms to be included could also cause the effect to decrease the withholding tax rates of the income tax in respect to conventions already in effect, as a consequence of the most-favoured-nation clause they contain.

    Life satisfaction of stroke survivors is known to be associated with socio-economic factors and the survivor's and his/her caregiver's quality of life, but their respective influence remains to be fully elucidated. To analyse the stroke survivors' life satisfaction 2 years after the event and its relationships with quality of life, socio-economic and stroke-related characteristics, and with informal caregivers' life satisfaction and quality of life . Over 18 months, all stroke patients from Luxembourg and north-eastern Portugal who lived at home were identified from the Inspection Générale de la Sécurité Sociale and hospital records, respectively. The clinical diagnosis of cerebrovascular disease was confirmed. We excluded all patients who declared that stroke did not result in neurological impairments at the time of stroke from the statistical analysis. The samples comprised 79 patients in Luxembourg and 48 in Portugal. Patients and the people they identified as their main caregivers were interviewed using validated questionnaires measuring life satisfaction, i.e. the Newcastle Stroke-Specific Quality of Life (Newsqol - 11 subscales), which identifies the areas affected by stroke among patients, and the World Health Organization Quality of Life - bref (Whoqol-bref - 4 subscales) of informal caregivers. Survivors without neurological impairment at the time of stroke were excluded. Data were analysed via multiple-regression models. Life satisfaction was higher among women and lower among subjects with impaired motor functions. It was lower among Portuguese respondents with low-level education (life satisfaction than did working people (-7.9/100). Controlling for socio-economic factors, life satisfaction was associated with feelings- Newsqol (slope 0.25) among Luxembourg residents, and with feelings-, mobility- and self-care-Newsqol (slopes 0.24, 0.27 and 0.33, respectively) among Portuguese respondents. Life satisfaction of patients was strongly related to that

    Full Text Available Abstract Background Spontaneous repair is limited after CNS injury or degeneration because neurogenesis and axonal regrowth rarely occur in the adult brain. As a result, cell transplantation has raised much interest as potential treatment for patients with CNS lesions. Several types of cells have been considered as candidates for such cell transplantation and replacement therapies. Foetal brain tissue has already been shown to have significant effects in patients with Parkinson's disease. Clinical use of the foetal brain tissue is, however, limited by ethical and technical problems as it requires high numbers of grafted foetal cells and immunosuppression. Alternatively, several reports suggested that mesenchymal stem cells, isolated from adult bone marrow, are multipotent cells and could be used in autograft approach for replacement therapies. Results In this study, we addressed the question of the possible influence of mesenchymal stem cells on neural stem cell fate. We have previously reported that adult rat mesenchymal stem cells are able to express nestin in defined culture conditions (in the absence of serum and after 25 cell population doublings and we report here that nestin-positive (but not nestin-negative mesenchymal stem cells are able to favour the astroglial lineage in neural progenitors and stem cells cultivated from embryonic striatum. The increase of the number of GFAP-positive cells is associated with a significant decrease of the number of Tuj1- and O4-positive cells. Using quantitative RT-PCR, we demonstrate that mesenchymal stem cells express LIF, CNTF, BMP2 and BMP4 mRNAs, four cytokines known to play a role in astroglial fate decision. In this model, BMP4 is responsible for the astroglial stimulation and oligodendroglial inhibition, as 1 this cytokine is present in a biologically-active form only in nestin-positive mesenchymal stem cells conditioned medium and 2 anti-BMP4 antibodies inhibit the nestin-positive mesenchymal

    The aim of this study was to assess the relationship between self-reported weight change, socio-economic status, and health-related quality of life (HRQOL) in patients with diabetes, 5 years after they underwent coronary angiography. Between 2013 and 2014, 1873 of 4391 patients (319 with diabetes) who underwent coronary angiography between 2008 and 2009 participated in a follow-up study. Three out of four domains of the World Health Organization Quality of Life (WHOQOL)-BREF (physical health, psychological health and social relationships) were surveyed during the follow-up period. To assess the relationship between weight change and HRQOL, generalized linear models were constructed for every dimension of the WHOQOL-BREF, with educational level as a predictor and sex, age, marital status, smoking status, hypertension, cholesterol, ischemic heart disease, acute myocardial infarction, and stable angina pectoris as covariates. The mean age of the patients was 70 years and almost three-quarters of the patients (72.7 %) were men. During the 12 months preceding the follow-up survey, 22.6 % of the patients reported weight loss, 20 % reported weight gain, and 57.4 % reported no weight change. There were significant differences in the HRQOL scores between patients who reported weight loss and those who reported either weight gain or unchanged weight. The most affected domains were physical and psychological health, with higher scores for patients who reported weight loss (54.7 and 67.2, respectively) than those who reported weight gain (46.3 and 58.5, respectively). The generalized linear model confirmed higher HRQOL scores among patients who reported weight loss and revealed an association between the HRQOL score and education level. Weight change and education level were associated with HRQOL in patients with diabetes. Self-reported weight loss and no weight change were positively associated with HRQOL in patients with diabetes, while weight gain was negatively

  13. Informal caregiving as a risk factor for type 2 diabetes in individuals with favourable and unfavourable psychosocial work environments

    Mortensen, J; Clark, A J; Lange, T

    2018-01-01

    AIM: To examine whether informal caregiving is associated with increased risk of type 2 diabetes (T2D), and whether job strain and social support at work modify the association. METHODS: Individual participant's data were pooled from three cohort studies-the French GAZEL study, the Swedish...... Longitudinal Occupational Survey of Health (SLOSH) and the British Whitehall II study-a total of 21,243 study subjects. Informal caregiving was defined as unpaid care for a closely related person. Job strain was assessed using the demand-control model, and questions on co-worker and supervisor support were...... combined in a measure of social support at work. Incident T2D was ascertained using registry-based, clinically assessed and self-reported data. RESULTS: A total of 1058 participants developed T2D during the up to 10 years of follow-up. Neither informal caregiving (OR: 1.09, 95% CI: 0.92-1.30) nor high job...

  14. German 2020 Energy Transition Index. Favourable trend, but no breakthrough; Energiewende-Index Deutschland 2020. Positive Tendenzen, aber noch keine Trendwende

    Vahlenkamp, Thomas; Frunzetti, Katharina [McKinsey and Company, Duesseldorf (Germany); Peters, Michael [McKinsey and Company, Berlin (Germany)

    2015-03-15

    Introduced in autumn 2012 and updated twice a year since, the German 2020 Energy Transition Index (EWI) shows its first signs ever of a favourable trend. At last the indicators have got moving, even though one can hardly speak of a breakthrough yet. In spite of the positive trend, especially in regard to electricity consumption and the rate of newly installed offshore wind power capacity, the envisaged goals are still a long way off. This holds particularly for major indicators such as CO{sub 2} emissions and price levels of household and industrial electricity.

  15. Assessing the impact of framing on the comparative favourability of nuclear power as an electricity generating option in the UK

    Jones, Christopher R.; Eiser, J. Richard; Gamble, Tim R.

    2012-01-01

    In 2007 the UK government's public consultation on the future of nuclear power courted much criticism. Three studies were conducted to assess whether key arguments used by government within this consultation might have influenced public opinion about the technology. Participants first read a passage of text that made salient certain positive (climate change mitigation, increased energy security) or negative (nuclear waste) aspects of the nuclear debate. Participants then completed a task that required them to create an electricity mix for the UK by varying the contributions made by each of five energy sources (coal, gas, nuclear, renewables and electric import). Study 1 seemed to indicate that pitching the debate in terms of climate change mitigation was effective in increasing endorsement of nuclear power. The results of studies 2 and 3, however, contested this conclusion, suggesting that these arguments were having little direct impact upon participants' preferences for nuclear power. The results of these studies hold implications for UK energy policy and attitude assessment and can contribute to the understanding of how the arguments used by government in the 2007 consultation might have influenced public opinion. - Highlights: ► Three studies investigate the acceptability of nuclear power in response to ‘framing’ used by government in 2007 UK consultation. ► Acceptability of nuclear power was compared against four energy sources in an ‘electricity calculator’ task. ► Study 1 showed an apparent increase in the endorsement of nuclear following climate change ‘framing’. ► Studies 2 and 3 contradict this finding, suggesting that ‘framing’ had a limited direct effect on preferences for nuclear power.

    2017-09-01

    The EurObserv'ER policy profiles give a snapshot of the renewable energy policy in the EU Member States. Main support instruments for incentivising electricity from renewable energy sources are feed-in tariffs and feed-in premiums. A subsidy instrument is used as well. Households operating small solar installations are entitled to tax benefits. Renewable heat production is promoted through four subsidy instruments. Renewable transport fuels are promoted by way of a bio-fuels blending quota scheme

  17. A customised cold-water immersion protocol favours one-size-fits-all protocols in improving acute performance recovery

    Zandvoort, Coen S.; de Zwart, Jelmer R.; van Keeken, Brenda L.; Viroux, Patrick J.F.; Tiemessen, Ivo J.H.

    The purpose of the present study was to investigate whether a customised cold-water immersion (CWIc) protocol was more effective in enhancing acute performance recovery than a one-size-fits-all CWI (CWIs) or active recovery (AR) protocol. On three separate testing days, 10 healthy, physically

  18. Pre-Treatment Deep Curettage Can Significantly Reduce Tumour Thickness in Thick Basal Cell Carcinoma While Maintaining a Favourable Cosmetic Outcome When Used in Combination with Topical Photodynamic Therapy

    Christensen, E.; Mork, C.; Foss, O. A.

    2011-01-01

    Topical photodynamic therapy (PDT) has limitations in the treatment of thick skin tumours. The aim of the study was to evaluate the effect of pre-PDT deep curettage on tumour thickness in thick (≥2 mm) basal cell carcinoma (BCC). Additionally, 3-month treatment outcome and change of tumour thickness from diagnosis to treatment were investigated. At diagnosis, mean tumour thickness was 2.3 mm (range 2.0-4.0). Pre- and post-curettage biopsies were taken from each tumour prior to PDT. Of 32 verified BCCs, tumour thickness was reduced by 50% after deep curettage (ρ≤0.001) . Mean tumour thickness was also reduced from diagnosis to treatment. At 3-month followup, complete tumour response was found in 93% and the cosmetic outcome was rated excellent or good in 100% of cases. In conclusion, deep curettage significantly reduces BCC thickness and may with topical PDT provide a favourable clinical and cosmetic short-term outcome.

    Niranthin, a lignan isolated from the aerial parts of the plant Phyllanthus amarus, exhibits a wide spectrum of pharmacological activities. In the present study, we have shown for the first time that niranthin is a potent anti-leishmanial agent. The compound induces topoisomerase I-mediated DNA–protein adduct formation inside Leishmania cells and triggers apoptosis by activation of cellular nucleases. We also show that niranthin inhibits the relaxation activity of heterodimeric type IB topois...

  20. Melanoma patients with unknown primary site or nodal recurrence after initial diagnosis have a favourable survival compared to those with synchronous lymph node metastasis and primary tumour.

    Benjamin Weide

    Full Text Available BACKGROUND: A direct comparison of prognosis between patients with regional lymph node metastases (LNM detected synchronously with the primary melanoma (primary LNM, patients who developed their first LNM subsequently (secondary LNM and those with initial LNM in melanoma with unknown primary site (MUP is missing thus far. PATIENTS AND METHODS: Survival of 498 patients was calculated from the time point of the first macroscopic LNM using Kaplan Meier and multivariate Cox hazard regression analysis. RESULTS: Patients with secondary LNM (HR = 0.67; p = 0.009 and those with initial LNM in MUP (HR = 0.45; p = 0.008 had a better prognosis compared to patients with primary LNM (median survival time 52 and 65 vs. 24 months, respectively. A high number of involved nodes, the presence of in-transit/satellite metastases and male gender had an additional independent unfavourable effect. CONCLUSIONS: Survival of patients with LNM in MUP and with secondary LNM is similar and considerably more favourable compared to those with primary LNM. This difference needs to be considered during patient counselling and for stratification purposes in clinical trials. The assumption of an immune privilege of patients with MUP which is responsible for rejection of the primary melanoma, and results in a favourable prognosis is not supported by our data.

  1. Predation success by a plant-ant indirectly favours the growth and fitness of its host myrmecophyte.

    Alain Dejean

    Full Text Available Mutualisms, or interactions between species that lead to net fitness benefits for each species involved, are stable and ubiquitous in nature mostly due to "byproduct benefits" stemming from the intrinsic traits of one partner that generate an indirect and positive outcome for the other. Here we verify if myrmecotrophy (where plants obtain nutrients from the refuse of their associated ants can explain the stability of the tripartite association between the myrmecophyte Hirtella physophora, the ant Allomerus decemarticulatus and an Ascomycota fungus. The plant shelters and provides the ants with extrafloral nectar. The ants protect the plant from herbivores and integrate the fungus into the construction of a trap that they use to capture prey; they also provide the fungus and their host plant with nutrients. During a 9-month field study, we over-provisioned experimental ant colonies with insects, enhancing colony fitness (i.e., more winged females were produced. The rate of partial castration of the host plant, previously demonstrated, was not influenced by the experiment. Experimental plants showed higher δ(15N values (confirming myrmecotrophy, plus enhanced vegetative growth (e.g., more leaves produced increased the possibility of lodging ants in leaf pouches and fitness (i.e., more fruits produced and more flowers that matured into fruit. This study highlights the importance of myrmecotrophy on host plant fitness and the stability of ant-myrmecophyte mutualisms.

    Cardiovascular (CV) diseases remain a leading global cause of death. Lowering blood pressure (BP) reduces the risk of CV complications, especially stroke and acute coronary events, and it delays the progression of kidney disease. Adequate non-pharmacological treatment improves the effectiveness of the antihypertensive therapy. A Mediterranean diet with high content of vegetables (rich in tomatoes) is associated with a reduced CV risk. The main objective of the present study was to assess whether the addition of standardised tomato extract (STE) or acetylsalicylic acid (ASA) to standard antihypertensive therapy can improve BP control in patients with arterial hypertension (HT). The study involved 82 high-risk hypertensive patients. Patients with primary HT at high to a very high total CV risk were randomised in a blinded fashion to one of two groups, i.e. the ASA and STE group. The patients had two visits, a baseline visit and one after four weeks of treatment. In all the patients, during each visit, clinical BP and ambulatory BP measurements (ABPM) were performed. Platelet aggregation was determined using the VerifyNow analyser. After four weeks of treatment in the STE group, there was a statistically significant reduction in 24-h systolic BP, diastolic BP, and mean arterial pressure values measured in ABPM (p high CV risk. This effect, together with the anti-aggregatory effect, may indicate the pleiotropic effect of tomato extract. This fact justifies further research into functional foods and gives new insights into STE as a food supplement that could have new therapeutic and prophylactic uses for the treatment of hypertensive patients with high CV risk and especially with obesity.

  3. Red fox ( Vulpes vulpes L.) favour seed dispersal, germination and seedling survival of Mediterranean Hackberry ( Celtis australis L.)

    2006-07-01

    Seeds of the Mediterranean Hackberry Celtis australis are often encountered in fox faeces. In order to evaluate the effect of gut transit on the size of seeds selected, the rates and speed of germination and on the survival of the seedlings, Mediterranean Hackberry seeds from fox faeces were germinated in a greenhouse. The results were compared with those of seeds taken from ripe, uneaten fruits. Fox-dispersed seeds were smaller and lighter than the control ones and had higher (74% vs. 57%) and more rapid germination (74.5 days vs. 99.2 days). Seedlings from fox-dispersed seeds showed significantly greater survival by the end of the study period (74.1% vs. 43.6%) than the control ones. Survival in seedlings from fox-dispersed seeds was related to germination date, late seedlings showing poorer survival. This relationship was not observed away in the control seedlings. Seed mass did not affect seedling survival. Seedling arising from fox-dispersed seeds grew faster than control ones. These results suggest that fox can play a relevant role as seed disperser of Mediterranean Hackberry.

    2012-11-01

    The role of repeated infusions of Levosimendan (LEVO) in patients with chronic advanced heart failure is still unclear. Thirty-three patients with chronic heart failure presenting clinical deterioration were randomized 2:1 to receive monthly infusions of LEVO (n = 22) or Furosemide (Controls, n = 11). At the first drug's administration, noninvasive hemodynamic evaluation was performed; before and after each infusion, we assessed NYHA class, systolic and diastolic function, functional mitral regurgitation, and brain natriuretic peptide (BNP) levels. Noninvasive hemodynamic in the LEVO group showed vasodilation and decrease in thoracic conductance (index of pulmonary congestion), whereas in Controls, only a reduced thoracic conductance was observed. In the LEVO group, systolic and diastolic function, ventricular volumes, severity of mitral regurgitation, and BNP levels improved over time from baseline and persisted 4 weeks after the last infusion (P < 0.01). In Controls, no change developed over time in cardiac function and BNP levels. In LEVO-treated patients, 1-year mortality tended to be lower than in those treated with Furosemide. In conclusion, serial LEVO infusions in advanced heart failure improved ventricular performance and favorably modulated neurohormonal activation. Multicenter randomized studies are warranted to test the effect of LEVO on long-term outcome.

    Niranthin, a lignan isolated from the aerial parts of the plant Phyllanthus amarus, exhibits a wide spectrum of pharmacological activities. In the present study, we have shown for the first time that niranthin is a potent anti-leishmanial agent. The compound induces topoisomerase I-mediated DNA–protein adduct formation inside Leishmania cells and triggers apoptosis by activation of cellular nucleases. We also show that niranthin inhibits the relaxation activity of heterodimeric type IB topoisomerase of L. donovani and acts as a non-competitive inhibitor interacting with both subunits of the enzyme. Niranthin interacts with DNA–protein binary complexes and thus stabilizes the ‘cleavable complex’ formation and subsequently inhibits the religation of cleaved strand. The compound inhibits the proliferation of Leishmania amastigotes in infected cultured murine macrophages with limited cytotoxicity to the host cells and is effective against antimony-resistant Leishmania parasites by modulating upregulated P-glycoprotein on host macrophages. Importantly, besides its in vitro efficacy, niranthin treatment leads to a switch from a Th2- to a Th1-type immune response in infected BALB/c mice. The immune response causes production of nitric oxide, which results in almost complete clearance of the liver and splenic parasite burden after intraperitoneal or intramuscular administration of the drug. These findings can be exploited to develop niranthin as a new drug candidate against drug-resistant leishmaniasis. PMID:23027614

  6. The p75 neurotrophin receptor evades the endolysosomal route in neuronal cells, favouring multivesicular bodies specialised for exosomal release

    Escudero, Claudia A.; Lazo, Oscal M.; Galleguillos, Carolina; Parraguez, Jose I.; Lopez-Verrilli, Maria A.; Cabeza, Carolina; Leon, Luisa; Saeed, Uzma; Retamal, Claudio; Gonzalez, Alfonso; Marzolo, Maria-Paz; Carter, Bruce D.; Court, Felipe A.; Bronfman, Francisca C.

    ABSTRACT The p75 neurotrophin receptor (p75, also known as NGFR) is a multifaceted signalling receptor that regulates neuronal physiology, including neurite outgrowth, and survival and death decisions. A key cellular aspect regulating neurotrophin signalling is the intracellular trafficking of their receptors; however, the post-endocytic trafficking of p75 is poorly defined. We used sympathetic neurons and rat PC12 cells to study the mechanism of internalisation and post-endocytic trafficking of p75. We found that p75 internalisation depended on the clathrin adaptor protein AP2 and on dynamin. More surprisingly, p75 evaded the lysosomal route at the level of the early endosome, instead accumulating in two different types of endosomes, Rab11-positive endosomes and multivesicular bodies (MVBs) positive for CD63, a marker of the exosomal pathway. Consistently, depolarisation by KCl induced the liberation of previously endocytosed full-length p75 into the extracellular medium in exosomes. Thus, p75 defines a subpopulation of MVBs that does not mature to lysosomes and is available for exosomal release by neuronal cells. PMID:24569882

  7. Competition for nitrogen between European beech and sycamore maple shifts in favour of beech with decreasing light availability.

    Simon, Judy; Li, Xiuyuan; Rennenberg, Heinz

    2014-01-01

    Plant species use different strategies for maximizing growth and fitness under changing environmental conditions. At the ecosystem level, seedlings in particular compete with other vegetation components for light and nitrogen (N), which often constitute growth-limiting resources. In this study, we investigated the effect of light availability on the competition for N between seedlings of European beech and sycamore maple and analysed the consequences of this competition for the composition of N metabolites in fine roots. Our results show different strategies in N acquisition between beech and sycamore maple. Both species responded to reduced light availability by adapting their morphological and physiological traits with a decrease in biomass and net assimilation rate and an increase in specific leaf area and leaf area ratio. For beech seedlings, competition with sycamore maple led to a reduction in organic N uptake capacity. Reduced light availability led to a decrease in ammonium, but an increase in glutamine-N uptake capacity in sycamore maple. However, this response was stronger compared with that of beech and was accompanied by reduced growth. Thus, our results suggest better adaptation of N acquisition to reduced light availability in beech compared with sycamore maple seedlings.

  8. The use of fibre-reinforced polymers (FRP in bridges as a favourable solution for the environment

    Żyjewski Artur

    2017-01-01

    Full Text Available The purpose of this article is to show the modern engineering, in which sustainability and taking care of ecology play a significant role. The authors are focused on FRP composite materials and their applications in civil engineering. Case studies showing renovation and design of new bridges with the use of FRP are presented and discussed to clarify benefits, which this solution provides. Main advantages of FRP materials in comparison with traditional ones, like concrete or steel are showed. The environmental impact of composites is described with respect to all life cycle of a product. Furthermore, some forms of waste management are covered. Last part of the paper refers to scientific description of the pedestrian bridge made of FRP, which was realized under the Fobridge research grant. The group of researchers headed by professor Chróścielewski from Gdansk University of Technology has developed a design solution of the pedestrian bridge manufactured in one production cycle. Moreover, the footbridge construction contains a significant share of a recyclable material commonly called PET. The article contains main characteristics of the structure and production process based on the resin infusion.

  9. Life inside a gall: closeness does not favour horizontal transmission of Rickettsia between a gall wasp and its parasitoid.

    Gualtieri, Liberata; Nugnes, Francesco; Nappo, Anna G; Gebiola, Marco; Bernardo, Umberto

    2017-07-01

    The incidence of horizontal transmission as a route for spreading symbiont infections is still being debated, but a common view is that horizontal transfers require intimate between-species relationships. Here we study a system that meets ideal requirements for horizontal transmission: the gall wasp Leptocybe invasa and its parasitoid Quadrastichus mendeli (Hymenoptera: Eulophidae). These wasps belong to the same subfamily, spend most of their lives inside the same minute gall and are both infected by Rickettsia, a maternally inherited endosymbiotic bacteria that infects several arthropods, sometimes manipulating their reproduction, like inducing thelytokous parthenogenesis in L. invasa. Despite intimate contact, close phylogenetic relationship and the parasitoid's host specificity, we show that host and parasitoid do not share the same Rickettsia. We provide indirect evidence that Rickettsia infecting Q. mendeli may be inducing thelytokous parthenogenesis, as the symbiont is densely present in the reproductive apparatus and is vertically transmitted. Phylogenetic analyses based on 16S and gltA placed this symbiont in the leech group. The confirmed and presumed parthenogenesis-inducing Rickettsia discovered so far only infect eulophid wasps, and belong to three different groups, suggesting multiple independent evolution of the parthenogenesis inducing phenotype. We also show some degree of cospeciation between Rickettsia and their eulophid hosts. © FEMS 2017. All rights reserved. For permissions, please e-mail: journals.permissions@oup.com.

  10. Expression of the RNA-binding protein RBM3 is associated with a favourable prognosis and cisplatin sensitivity in epithelial ovarian cancer

    Ehlen, Asa

    2010-08-20

    Abstract Background We recently demonstrated that increased expression of the RNA-binding protein RBM3 is associated with a favourable prognosis in breast cancer. The aim of this study was to examine the prognostic value of RBM3 mRNA and protein expression in epithelial ovarian cancer (EOC) and the cisplatin response upon RBM3 depletion in a cisplatin-sensitive ovarian cancer cell line. Methods RBM3 mRNA expression was analysed in tumors from a cohort of 267 EOC cases (Cohort I) and RBM3 protein expression was analysed using immunohistochemistry (IHC) in an independent cohort of 154 prospectively collected EOC cases (Cohort II). Kaplan Meier analysis and Cox proportional hazards modelling were applied to assess the relationship between RBM3 and recurrence free survival (RFS) and overall survival (OS). Immunoblotting and IHC were used to examine the expression of RBM3 in a cisplatin-resistant ovarian cancer cell line A2780-Cp70 and its cisplatin-responsive parental cell line A2780. The impact of RBM3 on cisplatin response in EOC was assessed using siRNA-mediated silencing of RBM3 in A2780 cells followed by cell viability assay and cell cycle analysis. Results Increased RBM3 mRNA expression was associated with a prolonged RFS (HR = 0.64, 95% CI = 0.47-0.86, p = 0.003) and OS (HR = 0.64, 95% CI = 0.44-0.95, p = 0.024) in Cohort I. Multivariate analysis confirmed that RBM3 mRNA expression was an independent predictor of a prolonged RFS, (HR = 0.61, 95% CI = 0.44-0.84, p = 0.003) and OS (HR = 0.62, 95% CI = 0.41-0.95; p = 0.028) in Cohort I. In Cohort II, RBM3 protein expression was associated with a prolonged OS (HR = 0.53, 95% CI = 0.35-0.79, p = 0.002) confirmed by multivariate analysis (HR = 0.61, 95% CI = 0.40-0.92, p = 0.017). RBM3 mRNA and protein expression levels were significantly higher in the cisplatin sensitive A2780 cell line compared to the cisplatin resistant A2780-Cp70 derivative. siRNA-mediated silencing of RBM3 expression in the A2780 cells resulted

    Aims: We present and analyse late-time observations of the Type-Ib supernova with possible pre-supernova progenitor detection, iPTF13bvn, which were done ~300 days after the explosion. We discuss them in the context of constraints on the supernova's progenitor. Previous studies have proposed two possible natures for the progenitor of the supernova, i.e. a massive Wolf-Rayet star or a lower-mass star in a close binary system. Methods: Our observations show that the supernova has entered the nebular phase, with the spectrum dominated by Mg I]λλ4571, [O I]λλ6300, 6364, and [Ca II]λλ7291, 7324 emission lines. We measured the emission line fluxes to estimate the core oxygen mass and compared the [O I]/[Ca II] line ratio with other supernovae. Results.The core oxygen mass of the supernova progenitor was estimated to be ≲0.7 M⊙, which implies initial progenitor mass that does not exceed ~15-17 M⊙.Since the derived mass is too low for a single star to become a Wolf-Rayet star, this result lends more support to the binary nature of the progenitor star of iPTF13bvn. The comparison of [O I]/[Ca II] line ratio with other supernovae also shows that iPTF13bvn appears to be in close association with the lower mass progenitors of stripped-envelope and Type-II supernovae.

    Surgical management of patients with multilevel CSM aims to decompress the spinal cord and restore the normal sagittal alignment. The literature lacks of high level evidences about the best surgical approach. Posterior decompression and stabilization in lordosis allows spinal cord back shift, leading to indirect decompression of the anterior spinal cord. The purpose of this study was to investigate the efficacy of posterior decompression and stabilization in lordosis for multilevel CSM. 36 out of 40 patients were clinically assessed at a mean follow-up of 5, 7 years. Outcome measures included EMS, mJOA Score, NDI and SF-12. Patients were asked whether surgery met their expectations and if they would undergo the same surgery again. Bone graft fusion, instrumental failure and cervical curvature were evaluated. Spinal cord back shift was measured and correlation with EMS and mJOA score recovery rate was analyzed. All scores showed a significative improvement (p 0.05). Ninety percent of patients would undergo the same surgery again. There was no deterioration of the cervical alignment, posterior grafted bones had completely fused and there were no instrument failures. The mean spinal cord back shift was 3.9 mm (range 2.5-4.5 mm). EMS and mJOA recovery rates were significantly correlated with the postoperative posterior cord migration (P lordosis is a valuable procedure for patients affected by multilevel CSM, leading to significant clinical improvement thanks to the spinal cord back shift. Postoperative lordotic alignment of the cervical spine is a key factor for successful treatment.

  13. The hydrogen bond between N-H or O-H and organic fluorine: favourable yes, competitive no.

    Taylor, Robin

    2017-06-01

    A study was made of X-H...F-C interactions (X = N or O) in small-molecule crystal structures. It was primarily based on 6728 structures containing X-H and C-F and no atom heavier than chlorine. Of the 28 451 C-F moieties in these structures, 1051 interact with X-H groups. However, over three-quarters of these interactions are either the weaker components of bifurcated hydrogen bonds (so likely to be incidental contacts) or occur in structures where there is a clear insufficiency of good hydrogen-bond acceptors such as oxygen, nitrogen or halide. In structures where good acceptors are entirely absent, there is about a 2 in 3 chance that a given X-H group will donate to fluorine. Viable alternatives are X-H...π hydrogen bonds (especially to electron-rich aromatics) and dihydrogen bonds. The average H...F distances of X-H...F-C interactions are significantly shorter for CR 3 F (R = C or H) and Csp 2 -F acceptors than for CRF 3 . The X-H...F angle distribution is consistent with a weak energetic preference for linearity, but that of H...F-C suggests a flat energy profile in the range 100-180°. X-H...F-C interactions are more likely when the acceptor is Csp 2 -F or CR 3 F, and when the donor is C-NH 2 . They also occur significantly more often in structures containing tertiary alcohols or solvent molecules, or with Z' > 1, i.e. when there may be unusual packing problems. It is extremely rare to find X-H...F-C interactions in structures where there are several unused good acceptors. When it does happen, there is often a clear reason, e.g. awkwardly shaped molecules whose packing isolates a donor group from the good acceptors.

  14. CLUB-MARTINI: Selecting Favourable Interactions amongst Available Candidates, a Coarse-Grained Simulation Approach to Scoring Docking Decoys.

    Qingzhen Hou

    Full Text Available Large-scale identification of native binding orientations is crucial for understanding the role of protein-protein interactions in their biological context. Measuring binding free energy is the method of choice to estimate binding strength and reveal the relevance of particular conformations in which proteins interact. In a recent study, we successfully applied coarse-grained molecular dynamics simulations to measure binding free energy for two protein complexes with similar accuracy to full-atomistic simulation, but 500-fold less time consuming. Here, we investigate the efficacy of this approach as a scoring method to identify stable binding conformations from thousands of docking decoys produced by protein docking programs. To test our method, we first applied it to calculate binding free energies of all protein conformations in a CAPRI (Critical Assessment of PRedicted Interactions benchmark dataset, which included over 19000 protein docking solutions for 15 benchmark targets. Based on the binding free energies, we ranked all docking solutions to select the near-native binding modes under the assumption that the native-solutions have lowest binding free energies. In our top 100 ranked structures, for the 'easy' targets that have many near-native conformations, we obtain a strong enrichment of acceptable or better quality structures; for the 'hard' targets without near-native decoys, our method is still able to retain structures which have native binding contacts. Moreover, in our top 10 selections, CLUB-MARTINI shows a comparable performance when compared with other state-of-the-art docking scoring functions. As a proof of concept, CLUB-MARTINI performs remarkably well for many targets and is able to pinpoint near-native binding modes in the top selections. To the best of our knowledge, this is the first time interaction free energy calculated from MD simulations have been used to rank docking solutions at a large scale.

  3. Entropy favours open colloidal lattices

    Mao, Xiaoming; Chen, Qian; Granick, Steve

    2013-03-01

    Burgeoning experimental and simulation activity seeks to understand the existence of self-assembled colloidal structures that are not close-packed. Here we describe an analytical theory based on lattice dynamics and supported by experiments that reveals the fundamental role entropy can play in stabilizing open lattices. The entropy we consider is associated with the rotational and vibrational modes unique to colloids interacting through extended attractive patches. The theory makes predictions of the implied temperature, pressure and patch-size dependence of the phase diagram of open and close-packed structures. More generally, it provides guidance for the conditions at which targeted patchy colloidal assemblies in two and three dimensions are stable, thus overcoming the difficulty in exploring by experiment or simulation the full range of conceivable parameters.

  4. Favourable effect of TNF-alpha inhibitor (infliximab) on Blau syndrome in monozygotic twins with a de novo CARD15 mutation

    Milman, Nils; Andersen, Claus B; Hansen, Annette

    2006-01-01

    Blau syndrome is a hereditary granulomatous disease caused by mutations in the CARD15 gene that is diagnosed in children of young age with exanthema/erythema, arthritis/periarthritis and/or uveitis. We report two cases of Blau syndrome in Danish Caucasian monozygotic male twins, exhibiting...... a heterozygous de novo R334W mutation in codon 334 of CARD15. The patients were initially diagnosed as having sarcoidosis. In both twins, symptoms (exanthema, arthritis/periarthritis) started at 1 year of age, and were followed by uveitis at 7-10 years of age. There was no involvement of the lungs or other...... quality of life. At follow up at 20 years of age (after 2-5 years of infliximab treatment) the twins had an almost normal physical appearance and a normal psychomotoric development, indicating a favourable short-term prognosis of the disease. Blau syndrome has pathologic, clinical and therapeutic features...

  7. Economic viability of Stratified Medicine concepts: An investor perspective on drivers and conditions that favour using Stratified Medicine approaches in a cost-contained healthcare environment.

    Fugel, Hans-Joerg; Nuijten, Mark; Postma, Maarten

    2016-12-25

    Stratified Medicine (SM) is becoming a natural result of advances in biomedical science and a promising path for the innovation-based biopharmaceutical industry to create new investment opportunities. While the use of biomarkers to improve R&D efficiency and productivity is very much acknowledged by industry, much work remains to be done to understand the drivers and conditions that favour using a stratified approach to create economically viable products and to justify the investment in SM interventions as a stratification option. In this paper we apply a decision analytical methodology to address the economic attractiveness of different SM development options in a cost-contained healthcare environment. For this purpose, a hypothetical business case in the oncology market has been developed considering four feasible development scenarios. The article outlines the effects of development time and time to peak sales as key economic value drivers influencing profitability of SM interventions under specific conditions. If regulatory and reimbursement challenges can be solved, decreasing development time and enhancing early market penetration would most directly improve the economic attractiveness of SM interventions. Appropriate tailoring of highly differentiated patient subgroups is the prerequisite to leverage potential efficiency gains in the R&D process. Also, offering a better targeted and hence ultimately more cost-effective therapy at reimbursable prices will facilitate time to market access and allow increasing market share gains within the targeted populations.

  8. Favourable Formations for CO{sub 2} Storage in the Almazan Basin; Formaciones Favorables para el Almacenamiento de CO{sub 2} en la Cuenca de Almazan

    Ruiz Rivas, C.; Lomba Falcon, L.

    2008-04-10

    Geological storage of carbon dioxide is one of the technological options that have been considered nowadays for global climate change mitigation. Underground CO{sub 2} storage requires the selection and identification of deep geological formations which must meet criteria for health and environmental safety in the middle-term of one thousand years. Deep permeable formations, depleted oil and gas fields, unminable coal seams and saline rocks are possible geological formations for CO{sub 2} storage. Some areas in our country have been selected to search potential CO{sub 2} reservoirs. Among these areas, sedimentary basins are highlighted because of their thick stratigraphic sequences and the availability of extensive geological data which are coming from fossil fuel exploration. In this report, the identification and selection of favourable geological formations in the Almazan basin is presented. A 3D simplified subsurface basin geological model that was based on a Geographic Information System is included as well. The report also includes suitable CO{sub 2} injection areas in the surface for the selected geological formations. Finally, a preliminary CO{sub 2} storage capacity estimation of a potential structural trap has been calculated, considering only physical CO{sub 2} trapping. This work has been undertaken in the framework of the Geological CO{sub 2} Storage Project which is within the Singular Strategic Project of the Ministry of Education and Science Generation, Capture and Storage advanced technologies of CO{sub 2}.

    2005-07-01

    Mantle cell lymphoma (MCL) is associated with a very unfavourable clinical course. This is particularly true for mantle cell lymphoma of the blastoid subtype (MCL-b). In order to define prognostic factors, we analysed the impact of immunoglobulin heavy chain variable (IgV H) gene somatic hypermutations on clinical outcome in a series of 21 cases of morphologically, phenotypically, and genotypically well-characterized MCL-b. Testing and estimation were performed using log-rank statistics and displayed on Kaplan-Meier graphs. Thirteen of 21 cases of MCL-b revealed a homology rate of > or = 99% compared to IgV H germ-line sequences in the databases and were scored as non-mutated. Eight of 21 cases (38%) of MCL-b were mutated. In MCL-b the mutation frequency was usually low and the mutation pattern was only rarely antigen-selected, in contrast to a control group of 11 cases with morphologically almost identical, but phenotypically and genotypically clearly distinguishable, diffuse large B cell lymphoma, derived, most likely, from germinal centre B cells. In our series of 21 MCL-b, positive IgV H mutational status, irrespective of varying homology thresholds, had no statistically significant prognostic impact on event-free or overall survival. However, mutated MCL-b tended to present more frequently at an earlier stage and without bone marrow involvement and to show lower rates of relapse and death, resulting in a more favourable clinical outcome.

    Favourable pain relief results on evoking autonomous twitches at myofascial trigger points with Electrical Twitch Obtaining Intramuscular Stimulation (ETOIMS). To document autonomic nervous system (ANS) dysfunction in Complex Regional Pain Syndrome (CRPS) from blood pressure (BP) and pulse/heart rate changes with ETOIMS. A patient with persistent pain regularly received serial ETOIMS sessions of 60, 90, 120 or ≥150 min over 24 months. Outcome measures include BP: systolic, diastolic, pulse pressure and pulse/heart rate, pre-session/immediate-post-session summed differences (SDPPP index), and pain reduction. His results were compared with that of two other patients and one normal control. Each individual represented the following maximal elicitable twitch forces (TWF) graded 1-5: maximum TWF2: control subject; maximum TWF3: CRPS patient with suspected ANS dysfunction; and maximum TWF4 and TWF5: two patients with respective slow-fatigue and fast-fatigue twitches who during ETOIMS had autonomous twitching at local and remote myotomes simultaneously from denervation supersensitivity. ETOIMS results between TWFs were compared using one-way analysis of variance test. The patients showed immediate significant pain reduction, BP and pulse/heart rate changes/reduction(s) except for diastolic BP in the TWF5 patient. TWF2 control subject had diastolic BP reduction with ETOIMS but not with rest. Linear regression showed TWF grade to be the most significant variable in pain reduction, more so than the number of treatments, session duration and treatment interval. TWF grade was the most important variable in significantly reducing outcome measures, especially pulse/heart rate. Unlike others, the TWF3 patient had distinctive reductions in SDPPP index. Measuring BP and pulse/heart rate is clinically practical for alerting ANS dysfunction maintained CRPS. SDPPP index (≥26) and pulse/heart rate (≥8) reductions with almost every ETOIMS treatment, plus inability to evoke

  11. Prey type and foraging ecology of Sanderlings Calidris alba in different climate zones: are tropical areas more favourable than temperate sites?

    Kirsten Grond

    2015-08-01

    Full Text Available Sanderlings (Calidris alba are long-distance migratory shorebirds with a non-breeding range that spans temperate and tropical coastal habitats. Breeding in the High Arctic combined with non-breeding seasons in the tropics necessitate long migrations, which are energetically demanding. On an annual basis, the higher energy expenditures during migration might pay off if food availability in the tropics is higher than at temperate latitudes. We compared foraging behaviour of birds at a north temperate and a tropical non-breeding site in the Netherlands and Ghana, respectively. In both cases the birds used similar habitats (open beaches, and experienced similar periods of daylight, which enabled us to compare food abundance and availability, and behavioural time budgets and food intake. During the non-breeding season, Sanderlings in the Netherlands spent 79% of their day foraging; in Ghana birds spent only 38% of the daytime period foraging and the largest proportion of their time resting (58%. The main prey item in the Netherlands was the soft-bodied polychaete Scolelepis squamata, while Sanderlings in Ghana fed almost exclusively on the bivalve Donax pulchellus, which they swallowed whole and crushed internally. Average availability of polychaete worms in the Netherlands was 7.4 g ash free dry mass (AFDM m−2, which was one tenth of the 77.1 g AFDM m−2 estimated for the beach in Ghana. In the tropical environment of Ghana the Sanderlings combined relatively low energy requirements with high prey intake rates (1.64 mg opposed to 0.13 mg AFDM s−1 for Ghana and the Netherlands respectively. Although this may suggest that the Ghana beaches are the most favourable environment, processing the hard-shelled bivalve (D. pulchellus which is the staple food could be costly. The large amount of daytime spent resting in Ghana may be indicative of the time needed to process the shell fragments, rather than indicate rest.

  15. An early burst of IFN-γ induced by the pre-erythrocytic stage favours Plasmodium yoelii parasitaemia in B6 mice

    2009-06-01

    Full Text Available Abstract Background In murine models of malaria, an early proinflammatory response has been associated with the resolution of blood-stage infection. To dissect the protective immune mechanims that allow the control of parasitaemia, the early immune response of C57BL/6 mice induced during a non-lethal plasmodial infection was analysed. Methods Mice were infected with Plasmodium yoelii 265BY sporozoites, the natural invasive form of the parasite, in order to complete its full life cycle. The concentrations of three proinflammatory cytokines in the sera of mice were determined by ELISA at different time points of infection. The contribution of the liver and the spleen to this cytokinic response was evaluated and the cytokine-producing lymphocytes were identified by flow cytometry. The physiological relevance of these results was tested by monitoring parasitaemia in genetically deficient C57BL/6 mice or wild-type mice treated with anti-cytokine neutralizing antibody. Finally, the cytokinic response in sera of mice infected with parasitized-RBCs was analysed. Results The early immune response of C57BL/6 mice to sporozoite-induced malaria is characterized by a peak of IFN-γ in the serum at day 5 of infection and splenic CD4 T lymphocytes are the major producer of this cytokine at this time point. Somewhat unexpected, the parasitaemia is significantly lower in P. yoelii-infected mice in the absence of IFN-γ. More precisely, at early time points of infection, IFN-γ favours parasitaemia, whereas helping to clear efficiently the blood-stage parasites at later time points. Interestingly, the early IFN-γ burst is induced by the pre-erythrocytic stage. Conclusion These results challenge the current view regarding the role of IFN-γ on the control of parasite growth since they show that IFN-γ is not an essential mediator of protection in P. yoelii-infected C57BL/6 mice. Moreover, the mice parasitaemia is more efficiently controlled in the absence of an

  17. Adherence to physical activity recommendations and its associated factors: an interregional population-based study

    Full Text Available Background. Though the influence of physical activity in preventing cardiovascular diseases is well documented, only a few comparative studies have determined the degree of adherence to physical activity recommendations among populations and identified the demographic, socioeconomic, behavioural and health-related factors associated with good compliance. Design and methods. Cross-sectional interregional NESCaV survey of 3133 subjects compared three populations, Luxembourg, Lorraine (France and Wallonia (Belgium, by using the International Physical Activity Questionnaire. Age and gender prevalence rates of physical activity were standardized to the European population. Results. The likelihood to meet the recommendations was higher in Luxembourg, after adjustment for age, gender, education, employment, weight status, morbidity score, health perception and level of importance attributed to the practice of physical activity (P<0.0001. The odds for meeting the recommendations were significantly higher among those with secondary than tertiary education. Compared to good self-health perception, subjects with poor or fair self-perceived health were less likely to meet the recommendations; this also applied to those attributing little or enough importance to physical activity compared with great importance. Conclusions. Region, education, self-perceived health and perception of importance of physical activity were emerged as independent determinants of meeting the recommendations. Awareness of the positive health effects of physical activity might thus be crucial for motivating the people to become more active. Further research is needed to explore potential region-specific factors which might explain the difference in population behaviours with respect to physical activity.

  19. Favouring more rigour when investigating human eating behaviour is like supporting motherhood and apple pie: A response to Robinson, Bevelander, Field, and Jones (2018).

    Hetherington, Marion M; Rolls, Barbara J

    2018-05-11

    In a 1987 paper, addressing questions about factors that influence the initiation, maintenance, and termination of food intake, we wrote, "development of systematic procedures to measure eating behaviour is essential if descriptive and inferential statistics are to be applied to answering such questions, giving them power and replicability" (Hetherington & Rolls, 1987 page 77). Therefore, as longstanding advocates of rigorous procedures in laboratory-based investigations of food intake, we welcome Robinson et al.'s (2018) clear recommendations for laboratory studies. However, this is akin to voting for "motherhood and apple pie", and few would argue against deployment of improved procedures for these studies. What then can we contribute to the debate in order to refine the recommendations made or add to them? Our most important message for researchers is that the central hypothesis or main research question will determine the most appropriate methods for any study. If a laboratory-based study is planned, then there are basic methodological questions that must be answered before proceeding to a final protocol. While such guidelines are needed to ensure basic methodological rigour, these should not be so prescriptive as to inhibit creativity. Here we provide several thoughts on how to advance studies of ingestive behaviour, including the need to apply appropriate controls, encouragement to move beyond convenience samples, and to remember the value of exploratory, observational, and naturalistic studies to complement laboratory-based studies.

    The study of the possibilities of conducting Deep Geological CO{sub 2} Storage inside Spanish territory is being performed through the Strategic Singular Project PS-120000-2005-2 of the National Program of Energy from the Education and Science Ministry, and called CO{sub 2} generation, sequestration and storage advanced technologies, sub project N3 CO{sub 2} Geological Storage This report studies the possibilities the Ebro basin offers for definitive CO{sub 2} storage as one of the Spanish selected areas from previous studies. The study and reinterpretation of the information obtained from the hydrocarbon exploration accomplished in the area has lead to the selection of a series of geological formations. These formations have been chosen attending certain characteristics such as their disposition, extension, depth and porosity. The study has also been conducted considering the characteristics of the geological formations above the CO{sub 2} storage formations so as to guarantee the sealing of the storage. The study includes the approximate estimation of the storage capacity for each of the formations in Megatons of CO{sub 2}, which can be useful in future decision making. Deep geological storage is one of the more relevant international initiatives in order to eliminate or reduce the anthropogenic CO{sub 2} emissions to the atmosphere. (Author) 68 refs.

    It has been suggested that human Mesenchymal Stem Cells (hMSC) could be used to repair numerous injured tissues. We have studied the potential use of hMSC in order to limit radiation-induced skin lesions. Immuno-deficient NOD/SCID mice were locally irradiated to the leg (30 Gy, dose rate 2.7 Gy/mn) using a {sup 60} Co source in order to induce a severe skin lesion. Cultured bone marrow hMSC were delivered intravenously to the mice. The irradiated skin samples were studied for the presence of the human cells, the severity of the lesions and the healing process. Macroscopic analysis and histology results showed that the lesions were evolving to a less severe degree of radiation dermatitis following hMSC transplant when compared to irradiated non-transplanted controls. Clinical scores for the studied skin parameters of treated mice were significantly improved. A faster healing was observed when compared to untreated mouse. Immuno-histology and Polymerase Chain reaction (PCR) analysis provided evidence that the human cells were found in the irradiated area. These results suggest a possible use of hMSC for the treatment of the early phase of the cutaneous radiation syndrome. A successful transplant of stem cells and subsequent reduction in radiation-induced complication may open the road to completely new strategies in cutaneous radiation syndrome therapy. (authors)

  7. Has the implementation of the TRIPS Agreement in Latin America and the Caribbean produced intellectual property legislation that favours public health?

    2004-11-01

    The World Trade Organization's Trade-Related Aspects of Intellectual Property Rights (TRIPS) Agreement establishes minimum standards for intellectual property rights, including patent protection for pharmaceuticals; therefore, it may make it difficult for developing countries to gain access to medicines, especially those countries that are the least developed. This study aims to determine whether implementation of the TRIPS Agreement in Latin American and Caribbean countries has generated patent legislation that is sensitive to public health needs. Legislation in 11 Latin American and Caribbean countries was analysed. The variables considered in the analysis were: the term of patents issued, patentable subject matter, transition periods (that is, time until legislation was enacted), reversal of the burden of proof of patent infringement, exhaustion of rights, compulsory licensing and the early working exception (which allows a country to complete all procedures necessary to register a generic product before the original patent expires). By 2000, all of the countries studied had reformed their legislation to conform to the agreement. Brazil and Argentina used the transition period until 2005 to grant patents in the pharmaceutical industry. All countries, except Panama, made use of the safeguards and flexibilities available through the agreement by including mechanisms for compulsory licensing in their legislation. Argentina; Bolivia, Colombia, Ecuador, Peru and Venezuela (countries that represented the Andean community); the Dominican Republic; and Panama included mechanisms to allow parallel importation. Mexico did not. Brazil only permits parallel importation after a compulsory licence has been issued. The early working exception is included in legislation in Brazil and the Dominican Republic.

  9. A cuboctahedral platinum (Pt79) nanocluster enclosed by well defined facets favours di-sigma adsorption and improves the reaction kinetics for methanol fuel cells.

    Mahata, Arup; Choudhuri, Indrani; Pathak, Biswarup

    2015-08-28

    The methanol dehydrogenation steps are studied very systematically on the (111) facet of a cuboctahedral platinum (Pt79) nanocluster enclosed by well-defined facets. The various intermediates formed during the methanol decompositions are adsorbed at the edge and bridge site of the facet either vertically (through C- and O-centres) or in parallel. The di-sigma adsorption (in parallel) on the (111) facet of the nanocluster is the most stable structure for most of the intermediates and such binding improves the interaction between the substrate and the nanocluster and thus the catalytic activity. The reaction thermodynamics, activation barrier, and temperature dependent reaction rates are calculated for all the successive methanol dehydrogenation steps to understand the methanol decomposition mechanism, and these values are compared with previous studies to understand the catalytic activity of the nanocluster. We find the catalytic activity of the nanocluster is excellent while comparing with any previous reports and the methanol dehydrogenation thermodynamics and kinetics are best when the intermediates are adsorbed in a di-sigma manner.

  10. Artificial marine habitats favour a single fish species on a long-term scale: the dominance of Boops boops around off-shore fish cages

    Rodrigo Riera

    2014-12-01

    Full Text Available Off-shore fish cages are new artificial habitats that can affect pelagic fish assemblages and constitute an important food source for wild fish assemblages. This aggregation has noticeable ecological consequences in cage areas in impoverished ecosystems such as those in the Canary archipelago (NE Atlantic Ocean. However, this new habitat could be dominated by a single species, reducing its positive ecological effects. Wild fish assemblages associated with an off-shore fish lease on the northeastern coast of Tenerife (Canary Islands were sampled for six years. Fish assemblage structure beneath fish cages and at controls ( > 500 m from cages differed significantly between locations, with 13 times greater abundance at cage locations. These differences were mainly explained by the dominance of bogue (Boops boops around fish cages. This trend was consistent in the long-term throughout the study period (2004-2009, affecting local fisheries. The presence of fish cages significantly altered wild fish assemblages in the study area, enhancing mainly biomass and abundance of one species, bogue, and causing shifts in species composition.

Independent of antigen dose, intraperitoneal administration of antigen increased the amount of TT-specific cytotoxic CD8β+ T cells within the cytokine-producing T-cell pool when compared to the non-cytokine producing T-cell compartment. Taken together, these results demonstrate that a full...... protein formulated in the CAF09 adjuvant and administered to pigs via the intraperitoneal route effectively generates a cytotoxic T-cell response. Moreover, we confirm the inverse relationship between the antigen dose and the induction of polyfunctional T cells in a large animal model. These finding can...

  13. Making the Outcomes of the Doha Development Round Favourable for Developing Countries: Reflections on a Feasible Proposal for a Special Safeguard Mechanism

    Francis Shasha Matambalya

    2010-06-01

    Full Text Available In principle, there is consensus among World Trade organisation members (WTO on the need to establish Special Safeguard Mechanisms (SSM for use by developing countries. Building on a survey of literature, empirical studies, and exchange of ideas through participation in the international debate on the subject matter, this paper outlines the architecture of a pro-development SSM. The elaboration is based on ten dimensions: country eligibility, criteria for selection of special products, triggers of safeguard action, precondition for application of safeguard action, geographic coverage, permissible remedies, restrictions on the levels of compensation, time scale, other rules, and treatment of developing countries. Compared to the SSG, it allows trigger levels at lower volumes and higher prices. Also, it differentiates demand increase and import surges, maintains linkages of domestic producers to long-run world market dynamics, and allows the computation of the price trigger on consignment by consignment basis.

  14. Does more favourable handling of the cerebrospinal fluid increase the diagnostic sensitivity of Borrelia burgdorferi sensu lato-specific PCR in Lyme neuroborreliosis?

    2018-04-01

    Tests for direct detection of Borrelia burgdorferi sensu lato (Bb) in Lyme neuroborreliosis (LNB) are needed. Detection of Bb DNA using PCR is promising, but clinical utility is hampered by low diagnostic sensitivity. We aimed to examine whether diagnostic sensitivity can be improved by the use of larger cerebrospinal fluid (CSF) volumes and faster handling of samples. Patients who underwent CSF examination for LNB were included. We collected two millilitres of CSF for PCR analysis, extracted DNA from the pellets within 24 h and analysed the eluate by two real-time PCR protocols (16S rRNA and OspA). Patients who fulfilled diagnostic criteria for LNB were classified as LNB cases and the rest as controls. Bb DNA in CSF was detected by PCR in seven of 28 adults with LNB. Two were Bb antibody negative. No Bb DNA was detected in CSF from 137 controls. Diagnostic sensitivity was 25% and specificity 100%. There was a non-significant trend towards larger CSF sample volume, faster handling of the sample, shorter duration of symptoms, and higher CSF cell count in the PCR-positive cases. We did not find that optimized handling of CSF increased diagnostic sensitivity of PCR in adults with LNB. However, our case series is small and we hypothesize that the importance of these factors will be clarified in further studies with larger case series and altered study design. PCR for diagnosis of LNB may be useful in cases without Bb antibodies due to short duration of symptoms.

  15. Opting out of dialysis – Exploring patients' decisions to forego dialysis in favour of conservative non-dialytic management for end-stage renal disease.

    2015-10-01

    Dialysis prolongs the life of people with end-stage renal disease (ESRD), but for patients who are elderly and suffer multiple comorbid illnesses the benefits of dialysis may be outweighed by its negative consequences. Non-dialytic conservative management has therefore become an alternative treatment route, yet little is known on patients' experience with choosing end-of-life treatment. To gain insight into the decision-making process leading to opting out of dialysis and the experience with conservative non-dialytic management from the patients' perspective. Qualitative study using semi-structured interviews. Interpretative phenomenological analysis was undertaken as the framework for data analysis. N = 9 ESRD participants who have taken the decision to forego dialysis were recruited from the advanced care programme under the National Healthcare Group, Singapore. Participants discussed life since ESRD diagnosis, and the personal and contextual factors that led them to choose conservative management. The perceived physical and financial burden of dialysis both for the individual but most importantly for their family, uncertainty over likely gains over risks which were fuelled by communication of negative dialysis stories of others, coupled with sense of life completion and achievement led them to refuse dialysis. All participants took ownership of their decision despite contrary advice by doctors and were content with their decision and current management. Study highlights the factors driving patients' decisions for conservative non-dialytic management over dialysis to allow medical professionals to offer appropriate support to patients through their decision-making process and in caring them for the rest of their lives. © 2013 John Wiley & Sons Ltd.

  16. Correlation between the 'negativating' of scintigraphy with granulocytes (SPN) labelled by HMPAO-99mTc and the favourable evolution of patients treated for osteitis

    1997-01-01

    Excepting the bacteriological 'negativating' after surgery, there exists at present no 'Gold-Standard' proving the sterilization of an infectious focus after osteitis. At present, only the absence of long-term recurrence allows to claim the healing. The aim of the study is to demonstrate the predictive value of SPN during the follow-up of patients over a span of 6 to 36 months (M). During a preliminary study 9 patients were regularly pursued by means of 5 criteria: clinical (fever, fistula), biological (polynucleosis, VS, CRP, fibrinogens), bacteriological, radiographical (standard or MRI) and scintigraphic, comprising an osseous scintigraphy and a SPN coupled at intervals of 48 hours, at M 0 and than at M 4 - M 6 if the examination is positive at M 0 , at M 6 - M 12 if the coupled scintigraphy is positive at M 4 - M 6 , and than each year up to M 36 . The following results were obtained. Seven patients presented scintigraphic results correlated with a favorable evolution after antibiotic therapy, essentially on the clinical-biological criteria. One patient has developed an infectious recurrence in spite of a scintigraphic negativating after 7 months from cessation of treatment, by the same germ, and a negativity of all the other criteria. Finally, one patient has presented a scintigraphic negativity, under treatment, in spite of a positive bacteriological sampling. The absence of non invasive criteria reliable in judging the sterilization of an osteitis focus implies a rather long antibiotic therapy. The question remains whether the negative SPN correlated with a favorable clinical follow-up may serve as a criterion of treatment cessation as well as if it may present certain iatrogenic secondary effects

    Porcine enzootic pneumonia (EP) caused by Mycoplasma hyopneumoniae adversely affects pig welfare and is associated with major economic losses in the pig industry worldwide. Transmission is predominantly by direct contact, but the role of indirect transmission remains poorly understood. This study examined survival of six M. hyopneumoniae isolates dried onto five different surfaces encountered in pig units and exposed to temperatures of 4, 25 and 37°C for up to 12 days. Survival of the organisms was determined by recovering the organism from the surface material and culturing in Friis broth. Data were analysed by logistic regression to identify factors influencing survival of M. hyopneumoniae. Maximum survival was 8 days for all isolates on at least one surface (except stainless steel) at 4°C and was limited to 2 days at 25 and 37°C. Overall, dust and polypropylene copolymer supported M. hyopneumoniae survival the longest when compared with other surface materials. In conclusion, we have demonstrated that M. hyopneumoniae can survive outside the host for at least 8 days. Understanding the transmission of Mycoplasma hyopneumoniae and optimizing biosecurity practices are keys to reducing the use of antimicrobial agents to control this pathogen. Direct transmission of the pathogen between pigs is the main route of spread and its lack of cell wall may compromise its resilience outside the host. The results from our study show that M. hyopneumoniae can survive for up to several days on dry surfaces and therefore may have the potential to infect pigs by indirect transmission. Factors influencing the survival of M. hyopneumoniae outside the host are further elucidated. © 2016 The Society for Applied Microbiology.

  18. Recurrent nocturnal hypoglycaemia as a cause of morning fatigue in treated Addison's disease--favourable response to dietary management: a case report.

    Petersen, Kristina S; Rushworth, R Louise; Clifton, Peter M; Torpy, David J

    2015-10-24

    Addison's disease, or primary adrenal insufficiency, is often associated with reduced well-being and fatigue despite use of currently recommended adrenal hormone replacement. Hypoglycaemia is a known manifestation of glucocorticoid deficiency, but is generally considered rare in adults and not relevant to troubling ongoing symptoms in patients with Addison's disease. A 43 year old woman with a three year history of Addison's disease complained of severe morning fatigue and headaches, despite standard glucocorticoid replacement therapy in the form of thrice daily hydrocortisone and mineralocorticoid replacement with fludrocortisone. Alternative glucocorticoid replacement regimens and the addition of dehydroepiandrosterone replacement therapy had no effect. Nocturnal hypoglycaemia was suspected and a 4-day continuous glucose monitor system (CGMS) revealed hypoglycaemia (interstitial glucose < 2.2 mmol/L) between 0200-0400 h on 3 of 4 days. The patient was counselled to take an evening snack designed to ensure slow absorption of ingested carbohydrates. Nocturnal hypoglycaemia was then absent on follow up CGMS assessment. The patient noted a marked symptomatic improvement in morning symptoms, but with persistent fatigue during the day. Currently, the best strategy for control of non-specific symptoms in treated Addison's disease is unknown, but it may be that investigation for hypoglycaemia and treatment, where necessary, could assist some sufferers to achieve improved wellbeing. A systematic study of this phenomenon in Addison's disease is required.

  19. High Intensity Interval Training Favourably Affects Angiotensinogen mRNA Expression and Markers of Cardiorenal Health in a Rat Model of Early-Stage Chronic Kidney Disease.

    The majority of CKD-related complications stem from cardiovascular pathologies such as hypertension. To help reduce cardiovascular complications, aerobic exercise is often prescribed. Emerging evidence suggests high intensity interval training (HIIT) may be more beneficial than traditional aerobic exercise. However, appraisals of varying forms of aerobic exercise, along with descriptions of mechanisms responsible for health-related improvements, are lacking. This study examined the effects of 8 weeks of HIIT (85% VO2max), versus low intensity aerobic exercise (LIT; 45-50% VO2max) and sedentary behaviour (SED), in an animal model of early-stage CKD. Tissue-specific mRNA expression of RAAS-related genes and CKD-related clinical markers were examined. Compared to SED, HIIT resulted in increased plasma albumin (p = 0.001), reduced remnant kidney weight (p = 0.028), and reduced kidney weight-body weight ratios (p = 0.045). Compared to LIT, HIIT resulted in reduced Agt mRNA expression (p = 0.035), reduced plasma LDL (p = 0.001), triglycerides (p = 0.029), and total cholesterol (p = 0.002), increased plasma albumin (p = 0.047), reduced remnant kidney weight (p = 0.005), and reduced kidney weight-body weight ratios (p = 0.048). These results suggest HIIT is a more potent regulator of several markers that describe and influence health in CKD.

  20. The beet cyst nematode Heterodera schachtii modulates the expression of WRKY transcription factors in syncytia to favour its development in Arabidopsis roots.

    Muhammad Amjad Ali

    Full Text Available Cyst nematodes invade the roots of their host plants as second stage juveniles and induce a syncytium which is the only source of nutrients throughout their life. A recent transcriptome analysis of syncytia induced by the beet cyst nematode Heterodera schachtii in Arabidopsis roots has shown that thousands of genes are up-regulated or down-regulated in syncytia as compared to root segments from uninfected plants. Among the down-regulated genes are many which code for WRKY transcription factors. Arabidopsis contains 66 WRKY genes with 59 represented by the ATH1 GeneChip. Of these, 28 were significantly down-regulated and 6 up-regulated in syncytia as compared to control root segments. We have studied here the down-regulated genes WRKY6, WRKY11, WRKY17 and WRKY33 in detail. We confirmed the down-regulation in syncytia with promoter::GUS lines. Using various overexpression lines and mutants it was shown that the down-regulation of these WRKY genes is important for nematode development, probably through interfering with plant defense reactions. In case of WRKY33, this might involve the production of the phytoalexin camalexin.

    2011-04-15

    The aim of this study is to report on a collective of 20 children from Belarus who had developed papillary thyroid carcinoma with pulmonary metastases after the Chernobyl disaster. In all children fractionated radioiodine therapy (RIT) was ceased before achieving complete remission due to a lack of further effects of {sup 131}I therapy and an increased risk of pulmonary fibrosis. The 20 children (12 girls) were treated with {sup 131}I using 50 MBq/kg body weight for thyroid remnant ablation and 100 MBq/kg for further therapy in intervals of 5-12 months. After five to six courses and a cumulative activity of about 24 GBq {sup 131}I no further RIT was conducted; the median thyroglobulin (TG) was 56 {mu}g/l at this time. All patients were followed for at least 10 years after cessation of RIT using diagnostic whole-body scintigraphy, CT of the chest, lung function testing and stimulated TG measurements every 1-3 years. During follow-up after the last RIT a continuous decline of values for TG levels of {proportional_to}35% per year was observed between individual visits. The median Tg level at the time of cessation of {sup 131}I therapy was 56 {mu}g/l; however, at the last visit 16 of 20 patients had a TG level {<=}10 {mu}g/l (median 2.4 {mu}g/l). Neither on diagnostic radioiodine whole-body scan nor on CT was progression of lung metastases observed. No significant pulmonary fibrosis developed. In spite of incomplete remission of thyroid cancer at cessation of RIT, a continuing spontaneous decline of TG and clinically stable partial remissions were observed in this collective of children. Therefore, if RIT does not show further effects, the administration of further courses should be handled restrictively. (orig.)

  3. The genetic basis of traits regulating sperm competition and polyandry: can selection favour the evolution of good- and sexy-sperm?

    Evans, Jonathan P; Simmons, Leigh W

    2008-09-01

    The good-sperm and sexy-sperm (GS-SS) hypotheses predict that female multiple mating (polyandry) can fuel sexual selection for heritable male traits that promote success in sperm competition. A major prediction generated by these models, therefore, is that polyandry will benefit females indirectly via their sons' enhanced fertilization success. Furthermore, like classic 'good genes' and 'sexy son' models for the evolution of female preferences, GS-SS processes predict a genetic correlation between genes for female mating frequency (analogous to the female preference) and those for traits influencing fertilization success (the sexually selected traits). We examine the premise for these predictions by exploring the genetic basis of traits thought to influence fertilization success and female mating frequency. We also highlight recent debates that stress the possible genetic constraints to evolution of traits influencing fertilization success via GS-SS processes, including sex-linked inheritance, nonadditive effects, interacting parental genotypes, and trade-offs between integrated ejaculate components. Despite these possible constraints, the available data suggest that male traits involved in sperm competition typically exhibit substantial additive genetic variance and rapid evolutionary responses to selection. Nevertheless, the limited data on the genetic variation in female mating frequency implicate strong genetic maternal effects, including X-linkage, which is inconsistent with GS-SS processes. Although the relative paucity of studies on the genetic basis of polyandry does not allow us to draw firm conclusions about the evolutionary origins of this trait, the emerging pattern of sex linkage in genes for polyandry is more consistent with an evolutionary history of antagonistic selection over mating frequency. We advocate further development of GS-SS theory to take account of the complex evolutionary dynamics imposed by sexual conflict over mating frequency.

  4. Pharmacological evidence favouring the traditional use of the root bark of Condalia buxifolia Reissek in the relief of pain and inflammation in mice.

    The Condalia buxifolia root bark infusion is used in traditional medicine in Brazil as antipyretic, anti-inflammatory and against dysentery. This study was designed to investigate whether the methanolic extract of the root bark of Condalia buxifolia (MECb) exhibits antinociceptive and anti-inflammatory effects in mice. Furthermore, also was investigated the involvement of glutamatergic and opioidergic system in the antinociceptive effect induced by MECb. The antinociceptive and anti-inflammatory effects of intra-gastric gavage (i.g.) administered MECb (10-300 mg/kg) were evaluated in mice subjected to chemical (formalin, acetic-acid, glutamate) or thermal (hot plate) models of pain. The involvement of opioid system in the antinociceptive effect of the MECb was investigated in formalin test. Furthermore, a nonspecific effect of MECb was evaluated by measuring locomotor activity and exploratory behavior in open field test. Finally, was performed a phytochemical analysis of MECb. The phytochemical analysis of MECb was performed through HPLC analysis showing that the alkaloid Condaline-A is the main constituent. The intragastric administration of MECb (100-300 mg/kg) significantly inhibited the nociception caused by acetic acid (48 ± 2%), inflammatory phase (49 ± 3%) and paw edema (32 ± 6) caused by formalin, and MECb (100mg/kg, i.g.) also inhibited nociception caused by glutamate (41 ± 7%). In addition, MECb (100-300 mg/kg, i.g.) increased the paw withdrawal latency in hot-plate test, without affecting the locomotor activity and exploratory behavior in open field test. Finally, the antinociceptive effects of MECb (100mg/kg, i.g.) were significantly reversed by naloxone (1mg/kg, i.p.) in the formalin test. These data show, for the first time, that MECb has significant antinociceptive and anti-inflammatory effects, which appear to be related to the inhibition of the glutamatergic system and the activation of opioid mechanism, besides present central effects.

    Full Text Available Abstract Background In Australia, ‘Alcohol Management Plans’ (AMPs provide the policy infrastructure for State and Commonwealth Governments to address problematic alcohol use among Aboriginal and Torres Strait Islanders. We report community residents’ experiences of AMPs in 10 of Queensland’s 15 remote Indigenous communities. Methods This cross-sectional study used a two-stage sampling strategy: N = 1211; 588 (48% males, 623 (52% females aged ≥18 years in 10 communities. Seven propositions about ‘favourable’ impacts and seven about ‘unfavourable’ impacts were developed from semi-structured interviews. For each proposition, one-sample tests of proportions examined participant agreement and multivariable binary logistic regressions assessed influences of gender, age (18–24, 25–44, 45–64, ≥65 years, residence (≥6 years, current drinking and Indigenous status. Confirmatory factor analyses estimated scale reliability (ρ, item loadings and covariances. Results Slim majorities agreed that: AMPs reduced violence (53%, p = 0.024; community a better place to live (54%, 0.012; and children were safer (56%, p < 0.001. More agreed that: school attendance improved (66%, p < 0.001; and awareness of alcohol’s harms increased (71%, p < 0.001. Participants were equivocal about improved personal safety (53%, p = 0.097 and reduced violence against women (49%, p = 0.362. The seven ‘favourable’ items reliably summarized participants’ experiences of reduced violence and improved community amenity (ρ = 0.90. Stronger agreement was found for six ‘unfavourable’ items: alcohol availability not reduced (58%, p < 0.001; drinking not reduced (56%, p < 0.001; cannabis use increased (69%, p < 0.001; more binge drinking (73%, p < 0.001; discrimination experienced (77%, p < 0.001; increased fines, convictions and criminal records for breaching restrictions (90%, p < 0

Please note that, in all the situations we present, the names are fictitious and used only to improve clarity.   Everyone can certainly agree that good communication is very important. Leaders should try to give feedback to their supervisees on their work and career so they can benefit from this information. Giving feedback provides personnel with an opportunity to understand what can they can improve or correct should there be some weaknesses in their technical or behavioural skills. It is also a chance to be congratulated for their efforts and dedication. Feedback should be given in a sincere and honest way, so that the person can accept the comments. The keys to giving feedback are:   • Speak the truth – even if it is difficult, have the courage to do it; &a...

  8. PLEADING IN FAVOUR OF STRATEGIC MANAGEMENT

    Teodor Frunzeti

    2016-10-01

    Full Text Available Strategic management focuses on future development of organizations, based on a vision and a strategy. If strategic leaders demonstrate epistemic competencies, business can take place not according to the zero sum game rule, where there are always winners and losers, but to a non-zero sum game rule, where there could be only winners and no losers. Epistemic competence is given by the scientific nature of knowledge, it breaks down the mental automatism generated by common day to day personal experience and it uses mathematical models and other specific methods. Strategic management and its practical content can best be understood within the context of the theory of organization, for organizations are indispensable for the general human and civilizational progress.

    1988-01-01

    The paper reports the proceedings of a seminar organised in co-operation with the International Atomic Energy Agency, on the small and medium sized nuclear reactors (SMSNRs). The seminar was held in Lausanne, Switzerland, 1987. At the seminar there was a strong impression of a possible requirement to move away from large (more than 1000 MWe) reactors. Also smaller reactors might be more suitable for private companies and developing countries with restricted grid sizes. There was also a strong feeling that the confidence in nuclear power of both private companies and the public could be greatly increased if the designs could be based on passive heat dissipation features rather than engineered safeguards to ensure reactor safety. Light water reactors, heavy water reactors, fast reactors, high temperature reactors, other small reactor systems, safety and licensing, and marketing prospects are all discussed. (UK)

  1. Intercomparison of passive radon-detectors under field conditions in epidemiological studies.

    Kreienbrock, L; Poffijn, A; Tirmarche, M; Feider, M; Kies, A; Darby, S C

    1999-05-01

    The Ardennes and Eifel region is a geologically distinct area covering parts of Germany, Belgium, France, and Luxembourg where enhanced concentrations of radon occur in some houses and other buildings. An international case-control study is being conducted to examine the role of radon in the etiology of lung cancer in this area. The radon detectors used are issued by different laboratories involving a variety of detector types and processes. A series of intercomparisons in houses was therefore conducted under similar conditions of exposure in the field. In most situations the different detectors gave similar results. Nevertheless, in some situations open and closed detectors yielded different results. Therefore, estimates of radon exposure have to be adjusted if results are to be pooled.

  2. Association of Sedentary Behavior Time with Ideal Cardiovascular Health: The ORISCAV-LUX Study

    Crichton, Georgina E.; Alkerwi, Ala'a

    2014-01-01

    Background Recently attention has been drawn to the health impacts of time spent engaging in sedentary behaviors. No studies have examined sedentary behaviors in relation to the newly defined construct of ideal cardiovascular health, which incorporates three health factors (blood pressure, total cholesterol, fasting plasma glucose) and four behaviors (physical activity, smoking, body mass index, diet). The purpose of this study was to examine associations between sedentary behaviors, including sitting time, and time spent viewing television and in front of a computer, with cardiovascular health, in a representative sample of adults from Luxembourg. Methods A cross-sectional analysis of 1262 participants in the Observation of Cardiovascular Risk Factors in Luxembourg study was conducted, who underwent objective cardiovascular health assessments and completed the International Physical Activity Questionnaire. A Cardiovascular Health Score was calculated based on the number of health factors and behaviors at ideal levels. Sitting time on a weekday, television time, and computer time (both on a workday and a day off), were related to the Cardiovascular Health Score. Results Higher weekday sitting time was significantly associated with a poorer Cardiovascular Health Score (p = 0.002 for linear trend), after full adjustment for age, gender, education, income and occupation. Television time was inversely associated with the Cardiovascular Health Score, on both a workday and a day off (p = 0.002 for both). A similar inverse relationship was observed between the Cardiovascular Health Score and computer time, only on a day off (p = 0.04). Conclusion Higher time spent sitting, viewing television, and using a computer during a day off may be unfavorably associated with ideal cardiovascular health. PMID:24925084

    Full Text Available Recently attention has been drawn to the health impacts of time spent engaging in sedentary behaviors. No studies have examined sedentary behaviors in relation to the newly defined construct of ideal cardiovascular health, which incorporates three health factors (blood pressure, total cholesterol, fasting plasma glucose and four behaviors (physical activity, smoking, body mass index, diet. The purpose of this study was to examine associations between sedentary behaviors, including sitting time, and time spent viewing television and in front of a computer, with cardiovascular health, in a representative sample of adults from Luxembourg.A cross-sectional analysis of 1262 participants in the Observation of Cardiovascular Risk Factors in Luxembourg study was conducted, who underwent objective cardiovascular health assessments and completed the International Physical Activity Questionnaire. A Cardiovascular Health Score was calculated based on the number of health factors and behaviors at ideal levels. Sitting time on a weekday, television time, and computer time (both on a workday and a day off, were related to the Cardiovascular Health Score.Higher weekday sitting time was significantly associated with a poorer Cardiovascular Health Score (p = 0.002 for linear trend, after full adjustment for age, gender, education, income and occupation. Television time was inversely associated with the Cardiovascular Health Score, on both a workday and a day off (p = 0.002 for both. A similar inverse relationship was observed between the Cardiovascular Health Score and computer time, only on a day off (p = 0.04.Higher time spent sitting, viewing television, and using a computer during a day off may be unfavorably associated with ideal cardiovascular health.

  5. DETERMINING THE EFFECT (THE SOCIAL COSTS OF EXCLUSION UNDER THE SOUTH AFRICAN EXCLUSIONARY RULE: SHOULD FACTUAL GUILT TILT THE SCALES IN FAVOUR OF THE ADMISSION OF UNCONSTITUTIONALLY OBTAINED EVIDENCE?

    D Ally

    2012-12-01

    Full Text Available Section 35(5 of the Constitution of the Republic of South Africa, 1996 governs the exclusion of unconstitutionally obtained evidence in criminal trials. Three groups of factors must be considered to assess whether unconstitutionally obtained evidence should either be excluded or admitted. This contribution is focussed on the third group of factors (also known as the "effect of exclusion", or the "social costs of exclusion" which consists of the "seriousness of the charge faced by the accused", and the "importance of the evidence to secure a conviction". This group of factors is concerned with the public interest in crime control. Some scholars argue that the "public mood" should be a weighty factor when our courts consider this group of factors. Against this background this article considers three issues: First, whether considerable weight should be attached to the "current mood" of society when our courts weigh and balance this group of factors against other relevant factors; secondly, whether a consideration of the "seriousness of the charge" and the "importance of the evidence for a successful prosecution" could possibly encroach upon the presumption of innocence; and, thirdly, whether factual guilt should be allowed to tip the scales in favour of the admission of unconstitutionally obtained evidence when the evidence is crucial for a conviction on a serious charge.

  6. Mycosporine-like amino acids and xanthophyll-cycle pigments favour a massive spring bloom development of the dinoflagellate Prorocentrum minimum in Grande Bay (Argentina), an ozone hole affected area

    2018-02-01

    In Grande Bay (Southern Patagonian Shelf) in a eutrophic and recirculating area slightly stratified during spring, we observed an intense (up to 1 × 107 cells L- 1) and shallow, quasi mono-specific bloom of the dinoflagellate Prorocentrum minimum. Peridinin was the most abundant carotenoid, but the relative amounts of the xanthophyll cycle carotenoids (diadinoxanthin + diatoxanthin = DT) to light-harvesting pigments were high (DT/Chl a ratio = 0.32 and DT/peridinin ratio = 0.40). Shinorine, usujirene, palythene, mycosporine-serine-glycine methyl ester and palythenic acid were the primary mycosporine-like amino acids (MAAs), followed by mycosporine-glycine, palythine, and porphyra-334. The ΣMAAs/Chl a ratios (up to 27.9 nmol/nmol) were in the upper range reported either in nutrient-replete dinoflagellate cultures or natural populations. We monitored, from space (using satellite ocean colour data), the spatial and temporal bloom variability (from September 22 to October 31, 2005) using an approach to discriminate dinoflagellate from diatom blooms. The results indicated that an intense diatom bloom started in early spring but was rapidly replaced by an intense bloom of the dinoflagellate P. minimum, although the nutrient concentrations were apparently not limiting. The most notorious change in this period was a sharp increase in the levels of solar UVB radiation (UVB index 9.0) as a consequence of the overpass of the polar vortex over this area. We postulated that the synthesis and accumulation of MAAs and xanthophyll pigments, were competitive advantages for the opportunistic red tide dinoflagellate P. minimum over the sensitive diatoms, favouring the development of their surface blooms in this seasonally solar UVB radiation (UVBR) affected area.

    Full Text Available The effects of different types and concentrations of electron donors (glucose, starch, methanol and sodium acetate on the formation of phosphine from anaerobic activated sludge that has been domesticated for a prolonged period were studied in small batch experiments. The results show that types and concentrations of electron donor have significant effects on the production of phosphine from anaerobic activated sludge. Among them, glucose was the most favourable electron donor, whereas sodium acetate was the least favourable electron donor for the removal of phosphorus and the production of phosphine. Higher concentrations of electron donors were more favourable for the reduction of phosphate into phosphine, and supplying more than nine times the amount of electron donor as theoretically required for the reduction of phosphate into phosphine was favourable for the production of phosphine.

    Yogurt consumption has been associated with higher nutrient intakes, better diet quality and improved metabolic profiles in adults. Few studies have investigated these associations in children. This study investigated the association of yogurt consumption with nutrient intakes, diet quality and metabolic profile in British children. Data from  1687 children aged 4-10 and 11-18 years of the National Diet and Nutrition Survey (NDNS) years 1-4 were analysed. Yogurt consumption was determined using a 4-day diet diary. Diet quality was assessed by the Healthy Eating Index 2010 (HEI-2010). Anthropometric measures, blood pressure, pulse pressure, plasma glucose, HbA1c, C-reactive protein, triacylglycerol, total cholesterol, high-and low-density cholesterol from NDNS were used. The highest tertile of yogurt consumption (T3) was associated with higher nutrient intakes, particularly for calcium (children 4-10 years: P consumption was associated with significantly lower pulse pressure in children aged 4-10 years and lower HbA1c concentration, being shorter and having a larger hip circumference in children aged 11-18 years, compared with non-yogurt consumers. This study suggests that British children who are yogurt consumers (> 60 g/day) have higher overall diet quality, nutrient intakes and adequacy, lower pulse pressure (children aged 4-10 years) and HbA1c concentrations (children aged 11-18 years), were shorter and had a smaller hip circumference (children aged 11-18 years).

Asimismo pone en relación la rentabilidad con el género en sus órganos de gobierno. Para ello, en un primer análisis se analiza la rentabilidad económica de las sociedades no financieras cotizadas en el mercado continuo y de aquellas que aunque no cotizan en dicho mercado están obligadas a presentar un Informe Anual de Gobierno Corporativo a la Comisión Nacional del Mercado de Valores desde el año 2004. Posteriormente se reduce la muestra tras la exclusión de las empresas no cotizadas en el mercado continuo. Los resultados muestran que una única entidad contribuyó a cambiar la rentabilidad y se coloca como modelo de estudio. Una característica diferenciadora de esta empresa es su forma jurídica, ya que se trata de una empresa cooperativa. / This paper analyzes which companies have more women on their board of directors in the moment previous to the publication of measures and recommendations about the female presence on the boards of directors of the Spanish big companies, including cooperatives. At the same time the study puts in relation the gender on boards with the return on assets. First, the current work starts with the sample of non-financial firms obliged to present an Annual Corporate Governance Report to the Spanish Securities Market Commission with data from 2004. Second, the sample is reduced; excluding the companies not listed in the continuous market. The results indicate that only one company contributed to change the return on assets and becomes a model to study. One characteristic of this entity is their juridical form, as a cooperative.

    This randomized, double blind, placebo-controlled, 8 week trial assessed the efficacy on metabolic changes produced by a consumption of a combination of bioactive food ingredients (epigallocatechin gallate, capsaicins, piperine and L-carnitine) versus a placebo, as part of a therapeutic 'lifestyle change' diet, in 86 overweight subjects. Forty-one patients (2/14 F/M; age 43.7 ± 8.5; BMI 30.3 ± 3.5 kg/m(2)) were randomized to the supplemented group and 45 (29/16; age 40.7 ± 10.2; BMI 30.0 ± 2.7) to the control group. We observed that consumption of the dietary supplement was associated with a significantly greater decrease in insulin resistance, assessed by homostasis model assessment (p < 0.001), leptin/adiponectin ratio (p < 0.04), respiratory quotient (p < 0.008). LDL-cholesterol levels (p < 0.01). Moreover, statistically significant differences were recorded between the two groups in relation to urinary norepinephrine levels (p < 0.001). Leptin, ghrelin, C-reactive protein decreased and resting energy expenditure increased significantly in the supplemented group (p < 0.05, 0.03, 0.02 and 0,02 respectively), but not in the placebo group; adiponectin decreased significantly in the placebo group (0.001) but not in the supplemented group, although no statistical significance between the groups was elicited. BMI, fat mass (assessed by DXA) and vascular endothelial growth factor significantly decreased, whilst the resting energy expenditure/free fat mass significantly increased in both groups. In general, a greater change was recorded in the supplemented group compared to the placebo, although no statistically significant difference between the two groups was recorded. These results suggest that the combination of bioactive food ingredients studied might be useful for the treatment of obesity-related inflammatory metabolic dysfunctions.

    Full Text Available Small business has a well-deserved reputation as the driver of job growth and as a key contributor to innovation. In the 12 years ending in 2013, small and medium-sized enterprises (SMEs accounted for about 90% of private sector job growth in Canada. What is less well-recognized, however, is that a small fraction of SMEs account for most of the job growth and innovation. As a result, governments have offered broad-based support for small businesses, rather than focusing on high-impact entrepreneurs. This approach is wasteful: firms that do not grow or innovate receive most of the benefits. Further, this approach can harm economic performance by promoting the expansion of smaller, lessefficient firms at the expense of larger ones. The federal government elected in 2015 is focussing new initiatives on innovative and growth-oriented businesses. Legislated reductions in the small business tax rate were reversed and targeted support for innovative SMEs was increased. While the change in direction is welcome, almost 85% of the $7 billion yearly funding for small business continues to provide broad-based support. The largest program is the special low rate of tax for small businesses, implemented to improve access to financing for capacity-expanding investment. This measure is harming economic performance because the cost of shifting capital and labour from large to smaller, less-efficient businesses outweighs the benefit from improving access to capital. Large subsidies for small business financing are also provided by the Business Development Bank of Canada (BDC. With access to cheap government funding, the BDC is profitable, but evaluated using a more realistic cost of financing, the bank operates at a substantial loss. This loss exceeds the benefit from improving access to capital, particularly for the bank’s direct-lending program. While there is a solid argument for supporting R&D, subsidies provided to small firms are so generous that they are harming economic performance. The federal government provides a 35% tax credit for R&D performed by small firms. Provincial tax credits raise the subsidy rate to about 42%. And those firms receiving support from the federal Industrial Research Assistance Program can have almost 60% of their project costs paid by the government. By way of contrast, large firms performing R&D receive subsidies from federal and provincial tax credits amounting to under a quarter of their costs, an intervention which improves economic performance. Canada has had what could be described as a small business policy – broad-based support for all small businesses. The newish federal government is moving to an entrepreneurship policy: new initiatives emphasize support for the high-impact firms and individuals that make an outsized contribution to Canada’s innovation and prosperity. Making the transition to the new framework will require overhauling legacy small business policies to free up resources for new initiatives and to secure fiscal savings. Three changes would pay big dividends: • Eliminate the small-business corporate income tax deduction. • Reduce the enhanced R&D tax credit rate to the same level as the regular credit. • Replace the BDC’s direct loan program with a loan guarantee program.

    Kümmerli, Rolf; van den Berg, Piet; Griffin, Ashleigh S; West, Stuart A; Gardner, Andy

    Repression of competition (RC) within social groups has been suggested as a key mechanism driving the evolution of cooperation, because it aligns the individual's proximate interest with the interest of the group. Despite its enormous potential for explaining cooperation across all levels of

  17. Another Argument in Favour of Wilcoxon's Signed Rank Test

    Rosenblatt, Jonathan; Benjamini, Yoav

    2013-01-01

    The Wilcoxon Signed Rank test is typically called upon when testing whether a symmetric distribution has a specified centre and the Gaussianity is in question. As with all insurance policies it comes with a cost, even if small, in terms of power versus a t-test, when the distribution is indeed Gaussian. In this note we further show that even when the distribution tested is Gaussian there need not be power loss at all, if the alternative is of a mixture type rather than a shift. The signed ran...

  18. A PLEADING IN FAVOUR OF THE CONSTITUTIONAL COURT

    Valentina BĂRBĂŢEANU

    2016-05-01

    Full Text Available Most of the European countries have chosen the centralized system of constitutional review, performed by a unique authority empowered with the competence of removing from the normative ensemble those legal provisions that do not comply with the principles and rules comprised in the Basic Law. This „European model” has proved to be more appropriate than the so-called „American model” in what concerns the compatibility with the European jurisdictional mechanism. Romania has adopted the same European trend and the Constitutional Court has become a very important actor in the Romanian legal landscape. From the very beginning of its activity, it has influenced in a great measure the national normative system. It has been sometimes criticized and accused that it interferes in an excessive way in the legislative process. Due to its competence to regulate the juridical conflicts between the public authorities and its possibility to repeal laws before their promulgation, it has been many times in the centre of heavy attacks, mostly from different political forces, often driven through mass media. Nevertheless, despite of its detractors, the Constitutional Court has proven, over the years, its ability to develop the Romanian normative system. The present paper intends to display the most significant contribution of the Romanian Constitutional Court in improving various legal regulations. In the same time and much more important, using concrete examples from the Court’s case-law, the paper also intends to demonstrate that the Constitutional Court of Romania has been a major factor of improving peoples’ life, removing unconstitutional obstacles set in front of the unimpeded exercise of their fundamental rights and freedoms.

  1. Notes on a local study on effectiveness and risk of X-ray mass chest screening

    Barbina, V.; Leonardi, M.

    1987-01-01

    This contribution consists of some special remarks, which may be of general interest, on the results of a local investigation on effectiveness and radiological risk of mass chest screening carried out in Friuli Venezia Giulia, an area of North-East Italy limited by well defined geographical and administrative borders. Population is about 1,300,000, ten percent of which is undergoing X-ray chest screening each year. The results of the study are in the working report of the technical workshop on mass screening organized on 4-5 December 1984 in Luxembourg by CEC and CEA. The study itself does not intend to have any character of generality. It has been proposed as an example of syntetic methodology for other similar local investigations which could possibly constitute a reliable basis for putting together larger ones, of national range, as already mentioned in the report. The conclusions on the results of this study seem obvious to us, however, we are aware that any obvious conclusion must be considered very carefully especially when dealing with a very complex matter as epidemiologic statistic, and particularly if we consider the previous papers on this subject as well as other reports presented in the workshop. Finally, we hope that our remarks may at least contribute as a good background for further discussion

    Currently, the Deep Geological Storage is the internationally most accepted option to store CO{sub 2}, whose main goal is to reduce the CO{sub 2} emissions to the atmosphere. This work, which has been carried out in the frame of The Strategic Singular Project entitled: CO{sub 2} generation, capture and storage advanced technologies summarizes a general methodology focused on the selection and modelling of favourable formations to store CO{sub 2} and to estimate their storage capacity. To conclude, the Duero basin suitability to allocate a CO{sub 2} storage plant has been quantified by integrating the Multi-criteria Evaluation Methods with the corresponding developed Geographical Information Systems.

  3. Population compliance with national dietary recommendations and its determinants: findings from the ORISCAV-LUX study.

    Alkerwi, Ala'a; Sauvageot, Nicolas; Nau, Anne; Lair, Marie-Lise; Donneau, Anne-Françoise; Albert, Adelin; Guillaume, Michèle

    2012-12-14

    The objective of the present study was to determine the proportion of adults meeting national recommendations for food and nutrient intake and to identify the demographic, socio-economic and behavioural factors that may contribute to weaken dietary compliance. ORISCAV-LUX is a cross-sectional study that took place in Luxembourg (2007-8). A representative stratified random sample of 1352 adults aged 18-69 years participated in the nationwide cardiovascular health survey. A FFQ was used to estimate food intake. Radar charts were built to compare graphically the compliance of the participants with different key dietary guidelines on the same set of axes. The thirteen food- and nutrient-based recommendations were scored and summed to create a recommendation compliance index (range -0·5 to 14). Ordinal logistic regression analyses were performed to determine the factors contributing to poor dietary compliance. Several food- and nutrient-based guidelines were insufficiently respected compared with others. The greatest gaps occurred in the adherence to grain and dairy product consumption guidelines, as well as to total fat and notably to SFA recommendations. Age, country of birth, economic status, smoking status and subject's awareness of the importance of balanced meals emerged as independently associated with weak dietary compliance. Obese subjects conformed more to dietary recommendations compared with normal-weight subjects. The findings underscore the need for specific nutrition education messages along with targeted interventions. Efforts should be continued to increase population awareness of the importance of a healthy lifestyle and a balanced diet.

    2015-10-01

    Full Text Available AbstractBiobanks are important resources for biomarker discovery and assay development. Biomarkers for Alzheimer's and Parkinson's Disease (BIOMARKAPD is a European multicenter study, funded by the EU Joint Programme - Neurodegenerative Disease Research (JPND, that aims to improve the clinical use of body fluid markers for the diagnosis and prognosis of Alzheimer’s disease (AD and Parkinson’s disease (PD. The objective was to standardize the assessment of existing assays and to validate novel fluid biomarkers for AD and PD. To support the validation of novel biomarkers and assays, a central and a virtual biobank for body fluids and associated data from subjects with neurodegenerative diseases have been established. In the central biobank, cerebrospinal fluid (CSF and blood samples were collected according to the BIOMARKAPD standardized preanalytical procedures (SOP and stored at Integrated BioBank of Luxembourg (IBBL. The virtual biobank provides an overview of available CSF, plasma, serum, and DNA samples at each site. Currently, at the central biobank of BIOMARKAPD samples are available from over 400 subjects with normal cognition, mild cognitive impairment (MCI, AD, frontotemporal dementia (FTD, vascular dementia (VaD, multiple system atrophy (MSA, progressive supranuclear palsy (PSP, PD, PD with dementia, and dementia with Lewy bodies (DLB. The virtual biobank contains information on over 8600 subjects with varying diagnoses from 21 local biobanks. A website has been launched to enable sample requests from the central biobank and virtual biobank.

  5. Radon and lung cancer: protocol and procedures of the multicentre studies in the Ardennes-Eifel region, Brittany and the Massif Central region

    Poffijn, A.; Darby, S.

    1992-01-01

    As part of a European coordinated project, the Ardennes-Eifel study was set up. In this project the study area coincides more or less with a geological zone, situated partly in France, Belgium, Luxembourg and Germany. In a first phase, a common protocol was worked out, dealing with general items as the selection of cases and (hospital/community) controls, the residential criteria for inclusion in the study and the specifications of the radon measurements. Much attention was given to the disease for the hospital controls and a list of ineligible diseases, most strongly related to tobacco, was agreed upon. A common core questionnaire is used, including items such as residential history since birth, occupational history, exposure to passive smoke (for non-smokers and occasional smokers) and educational attainment of the partner. Each country is also free to include additional items of its own. In France, this case-control study is extended to the granitic region of Britanny and in a second period to the region of the Massif Central. In these studies as well as in the national German study on radon and lung cancer, a protocol in all points comparable to that of the Ardennes study is used. (author)

  6. Ethical values in emergency medical services: A pilot study.

    Bremer, Anders; Herrera, María Jiménez; Axelsson, Christer; Martí, Dolors Burjalés; Sandman, Lars; Casali, Gian Luca

    2015-12-01

    Ambulance professionals often address conflicts between ethical values. As individuals' values represent basic convictions of what is right or good and motivate behaviour, research is needed to understand their value profiles. To translate and adapt the Managerial Values Profile to Spanish and Swedish, and measure the presence of utilitarianism, moral rights and/or social justice in ambulance professionals' value profiles in Spain and Sweden. The instrument was translated and culturally adapted. A content validity index was calculated. Pilot tests were carried out with 46 participants. This study conforms to the ethical principles for research involving human subjects and adheres to national laws and regulations concerning informed consent and confidentiality. Spanish professionals favoured justice and Swedish professionals' rights in their ambulance organizations. Both countries favoured utilitarianism least. Gender differences across countries showed that males favoured rights. Spanish female professionals favoured justice most strongly of all. Swedes favour rights while Spaniards favour justice. Both contexts scored low on utilitarianism focusing on total population effect, preferring the opposite, individualized approach of the rights and justice perspectives. Organizational investment in a utilitarian perspective might jeopardize ambulance professionals' moral right to make individual assessments based on the needs of the patient at hand. Utilitarianism and a caring ethos appear as stark opposites. However, a caring ethos in its turn might well involve unreasonable demands on the individual carer's professional role. Since both the justice and rights perspectives portrayed in the survey mainly concern relationship to the organization and peers within the organization, this relationship might at worst be given priority over the equal treatment and moral rights of the patient. A balanced view on ethical perspectives is needed to make professionals observant and

  17. Is the public willing to pay for hydrogen buses? A comparative study of preferences in four cities

    O'Garra, Tanya; Mourato, Susana; Garrity, Lisa; Schmidt, Patrick; Beerenwinkel, Anne; Altmann, Matthias; Hart, David; Graesel, Cornelia; Whitehouse, Simon

    2007-01-01

    This paper presents results from the international AcceptH2 study (http://www.accepth2.com) of acceptability and preferences for hydrogen fuel cell (FC) buses. Using the contingent valuation method, this paper compares public willingness to pay (WTP) for the air pollution reductions associated with a scenario of large-scale introduction of hydrogen (H 2 ) FC buses in four cities: Berlin, London, Luxembourg and Perth. Results indicate that bus users in all cities have a positive WTP for H 2 buses, and that values (adjusted to the cost of living in each city) are very similar across geographical locations (ranging from WTP an extra Euro 0.29 to Euro 0.35 per single bus fare). Non-bus users were also interviewed in London and Perth, in order to capture values for the whole populations in these cities. Combined results for bus users and non-bus users confirm that overall residents in these cities are willing to pay extra (in taxes) to support the large-scale introduction of H 2 -buses

  18. Estimating spatially distributed soil texture using time series of thermal remote sensing - a case study in central Europe

    Müller, Benjamin; Bernhardt, Matthias; Jackisch, Conrad; Schulz, Karsten

    2016-09-01

    For understanding water and solute transport processes, knowledge about the respective hydraulic properties is necessary. Commonly, hydraulic parameters are estimated via pedo-transfer functions using soil texture data to avoid cost-intensive measurements of hydraulic parameters in the laboratory. Therefore, current soil texture information is only available at a coarse spatial resolution of 250 to 1000 m. Here, a method is presented to derive high-resolution (15 m) spatial topsoil texture patterns for the meso-scale Attert catchment (Luxembourg, 288 km2) from 28 images of ASTER (advanced spaceborne thermal emission and reflection radiometer) thermal remote sensing. A principle component analysis of the images reveals the most dominant thermal patterns (principle components, PCs) that are related to 212 fractional soil texture samples. Within a multiple linear regression framework, distributed soil texture information is estimated and related uncertainties are assessed. An overall root mean squared error (RMSE) of 12.7 percentage points (pp) lies well within and even below the range of recent studies on soil texture estimation, while requiring sparser sample setups and a less diverse set of basic spatial input. This approach will improve the generation of spatially distributed topsoil maps, particularly for hydrologic modeling purposes, and will expand the usage of thermal remote sensing products.

  20. Use of social media by Western European hospitals: longitudinal study.

    Van de Belt, Tom H; Berben, Sivera A A; Samsom, Melvin; Engelen, Lucien J L P G; Schoonhoven, Lisette

    2012-05-01

    Patients increasingly use social media to communicate. Their stories could support quality improvements in participatory health care and could support patient-centered care. Active use of social media by health care institutions could also speed up communication and information provision to patients and their families, thus increasing quality even more. Hospitals seem to be becoming aware of the benefits social media could offer. Data from the United States show that hospitals increasingly use social media, but it is unknown whether and how Western European hospitals use social media. To identify to what extent Western European hospitals use social media. In this longitudinal study, we explored the use of social media by hospitals in 12 Western European countries through an Internet search. We collected data for each country during the following three time periods: April to August 2009, August to December 2010, and April to July 2011. We included 873 hospitals from 12 Western European countries, of which 732 were general hospitals and 141 were university hospitals. The number of included hospitals per country ranged from 6 in Luxembourg to 347 in Germany. We found hospitals using social media in all countries. The use of social media increased significantly over time, especially for YouTube (n = 19, 2% to n = 172, 19.7%), LinkedIn (n =179, 20.5% to n = 278, 31.8%), and Facebook (n = 85, 10% to n = 585, 67.0%). Differences in social media usage between the included countries were significant. Social media awareness in Western European hospitals is growing, as well as its use. Social media usage differs significantly between countries. Except for the Netherlands and the United Kingdom, the group of hospitals that is using social media remains small. Usage of LinkedIn for recruitment shows the awareness of the potential of social media. Future research is needed to investigate how social media lead to improved health care.
