Sacubitril was recently approved by the Food and Drug Administration for use in combination with valsartan for the treatment of patients with heart failure with reduced ejection fraction. As a prodrug, sacubitril must be metabolized (hydrolyzed) to its active metabolite sacubitrilat (LBQ657) to exert its intended therapeutic effects. Thus, understanding the determinants of sacubitril activation will lead to the improvement of sacubitril pharmacotherapy. The objective of this study was to identify the enzyme(s) responsible for the activation of sacubitril, and determine the impact of genetic variation on sacubitril activation. First, an incubation study of sacubitril with human plasma and the S9 fractions of human liver, intestine, and kidney was conducted. Sacubitril was found to be activated by human liver S9 fractions only. Moreover, sacubitril activation was significantly inhibited by the carboxylesterase 1 (CES1) inhibitor bis-(p-nitrophenyl) phosphate in human liver S9. Further incubation studies with recombinant human CES1 and carboxylesterase 2 confirmed that sacubitril is a selective CES1 substrate. The in vitro study of cell lines transfected with wild-type CES1 and the CES1 variant G143E (rs71647871) demonstrated that G143E is a loss-of-function variant for sacubitril activation. Importantly, sacubitril activation was significantly impaired in human livers carrying the G143E variant. In conclusion, sacubitril is selectively activated by CES1 in human liver. The CES1 genetic variant G143E can significantly impair sacubitril activation. Therefore, CES1 genetic variants appear to be an important contributing factor to interindividual variability in sacubitril activation, and have the potential to serve as biomarkers to optimize sacubitril pharmacotherapy.

Horneck, G.

1996-01-01

In view of the space station era, the European Space Agency has initiated a review and planning document for space life sciences. Radiation biology includes dosimetry of the radiation field and its modification by mass shielding, studies on the biological responses to radiation in space, on the potential impact of space flight environment on radiation effects, and assessing the radiation risks and establishing radiation protection guidelines. To reach a better understanding of the processes leading to the origin, evolution and distribution of life, exobiological activities include the exploration of the solar system, the collection and analysis of extraterrestrial samples and the utilization of space as a tool for testing the impact of space environment on organics and resistant life forms.

Satellites, comprising nine tonnes of hardware and sixty experiments, will be placed in orbit with a view to giving scientists a new perspective on the Sun, the Earth's magnetic environment and the universe in general. ISO, the Infrared Space Observatory, will allow astronomers to study all types of objects in the so1al. system - from nearby planets to the farthermost galaxies - with unparalleled sensitivity through the invisible, cold light of infrared radiation. Soho, the solar observatory, will be the fist satellite to continuously observe the Sun in detail, and will do so for at least two yews. The quartet of identical Cluster satellites will probe the Earth's magnetosphere in order to study the storms that can occur there which disrupt radio communications or electrical power supplies on Earth. As Roger Bonnet, Director of the European Space Agency's science programme, points out: "For the programme, this year marks the culmination often years of endeavour now drawing to a close. This shows that Europe is now taking the lead in in situ exploration of the universe". On 23 May ISO successfully completed final testing which validated the satellite's technical performance. It is currently on its way to Guiana onboard the Ariana. It will be launched from the Space Centre at Kourou by an Ariane 44P launcher in late October. On 14 June Soho will undergo similar checkouts which should give it a clean bill of health for dispatch to the Kennedy Space Center (Florida). It is scheduled for a launch on 30 October by NASA's Atlas rocket. Authorisation to dispatch the Cluster quartet to Kourou should be given in late June with a view to a launch at the end of the year on a flagship launcher: the first Ariane-5, which is set to become the most competitive launcher on the world market, Another milestone in space exploration is in the offing: the journey over the Sun's north pole by ESA's Ulysses probe begins this month and will continue through to September.

Technology is developed at the European Space Agency (ESA) under several programmes: corporate and domain specific, mandatory and optional, with different time horizons and covering different levels of the TRL scale. To improve the transparency and efficiency of the complete process, it was felt necessary to establish an agreed end to end process for the management of all technology R&D activity that could: Include all ESA programmes and consider the requirements of European users Lead to coordinated multi-year work plan and yearly procurement plans Prepare and enable future European space programmes Be harmonized with national initiatives in Europe Thereby establishing the basis for a product policy to reduce risks to technology users, reduce costs and delays, and enhance industrial competitiveness and non-dependence. In response to the above needs, ESA has developed a technology management process called the ESA End-to-End process (E2E), from establishment of the strategy to the monitoring and evaluation of R&D results. In this paper, the complete process will be described in detail including a discussion on its strengths and limitations, and its links to the wider European Harmonization process. The paper will be concluded with the introduction of the ESA Technology Tree: a basic tool to structure and facilitate communication about technology issues.

The European Space Agency has a long history of cooperating with NASA in human spaceflight, having developed the Spacelab module for carrying in the payload bay of the Space Shuttle. This book tells of the development of ESA’s Columbus microgravity science laboratory of the International Space Station and the European astronauts who work in it. From the beginning, ESA has been in close collaboration on the ISS, making a significant contribution to the station hardware. Special focus is given to Columbus and Copula as well as station resupply using the ATV. Each mission is also examined individually, creating a comprehensive picture of ESA's crucial involvement over the years. Extensive use of color photographs from NASA and ESA to depict the experiments carried out, the phases of the ISS construction, and the personal stories of the astronauts in space highlights the crucial European work on human spaceflight.

Cross-cultural issues in space operations: A survey study among ground personnel of the European Space Agency

Sandal, Gro Mjeldheim; Manzey, Dietrich

2009-12-01

Today's space operations involve co-working of people with different ethnical, professional and organisational backgrounds. The aim of this study was to examine the implications of cultural diversity for efficient collaboration within the European Space Agency (ESA), and between ESA employees and representatives from other agencies. ESA employees from European countries ( N=576) answered to the CULT Ground Survey. The results showed that differences in relation to leadership and decision making were the most important issues thought to interfere with efficient co-working within ESA, and between ESA employees and colleagues from other agencies. Employees who collaborated with more than three nationalities within ESA indicated most challenges in co-working due to differences in compliance, behavioural norms and competitiveness. Challenges in co-working differed between agencies, and these differences were consistent with value differences in the national populations. The results may have applied value for training of European employees working in international space program teams.

Estimation of European Union residential sector space cooling potential

International Nuclear Information System (INIS)

Jakubcionis, Mindaugas; Carlsson, Johan

2017-01-01

Data on European residential space cooling demands are scarce and often of poor quality. This can be concluded from a review of the Comprehensive Assessments on the energy efficiency potential in the heating and cooling sector performed by European Union Member States under Art. 14 of the Energy Efficiency Directive. This article estimates the potential space cooling demands in the residential sector of the EU and the resulting impact on electricity generation and supply systems using the United States as a proxy. A georeferenced approach was used to establish the potential residential space cooling demand in NUTS-3 regions of EU. The total potential space cooling demand of the EU was estimated to be 292 TW h for the residential sector in an average year. The additional electrical capacity needed was estimated to 79 GW. With proper energy system development strategies, e.g. matching capacity of solar PV with cooling demand, or introduction of district cooling, the stresses on electricity system from increasing cooling demand can be mitigated. The estimated potential of space cooling demand, identified in this paper for all EU Members States, could be used while preparing the next iteration of EU MS Comprehensive Assessments or other energy related studies. - Highlights: • An estimation of EU space cooling demand potential in residential sector is presented. • An estimate of space cooling demand potential is based on using USA data as a proxy. • Significant cooling demand increase can be expected. • Cooling demand increase would lead to increased stress in energy supply systems. • Proper policies and strategies might measurably decrease the impact on energy systems.

Energy-Extended CES Aggregate Production: Current Aspects of Their Specification and Econometric Estimation

Paul E. Brockway

2017-02-01

Full Text Available Capital–labour–energy Constant Elasticity of Substitution (CES production functions and their estimated parameters now form a key part of energy–economy models which inform energy and emissions policy. However, the collation and guidance as to the specification and estimation choices involved with such energy-extended CES functions is disparate. This risks poorly specified and estimated CES functions, with knock-on implications for downstream energy–economic models and climate policy. In response, as a first step, this paper assembles in one place the major considerations involved in the empirical estimation of these CES functions. Discussions of the choices and their implications lead to recommendations for CES empiricists. The extensive bibliography allows those interested to dig deeper into any aspect of the CES parameter estimation process.

1988-08-01

Ces-VP is a prototype rule-based expert system for consulting the vector programming, based on the knowledge of vectorization of nuclear codes at JAERI during these 10 years. Experts in vectorization can restructure nuclear codes with high performance on vector processors, since they have know-how for choosing the best technique among a lot of techniques that were acquired from the experience of vectorization in the past. Frequency in trial and error will be reduced if a beginner can easily use the know-how of experts. In this report, at first the contents of Ces-VP and its intention are shown. Then, the method for acquiring the know-how of vectorization and the method for making rules from the know-how are described. The outline of Ces-VP implemented on Fujitsu expert tool ESHELL is described. Finally, the availability of Ces-VP is evaluated from the data gathered from practical use and its present problems are discussed. (author)

Wound-Healing Potential of Cultured Epidermal Sheets Is Unaltered after Lyophilization: A Preclinical Study in Comparison to Cryopreserved CES

2013-01-01

Full Text Available Lyophilized Cultured Epidermal Sheets (L-CES have been reported to be as effective as the cryopreserved CES (F-CES in treating skin ulcers. However, unlike F-CES, no preclinical study assessing wound-healing effects has been conducted for L-CES. The present study was set out to investigate the microstructure, cytokine profile, and wound-healing effects of L-CES in comparison to those of F-CES. Keratinocytes were cultured to prepare CES, followed by cryopreservation at −70°C and lyophilization. Under microscopic observation, intact cells with apparent intracellular junctions were observed in L-CES. The L-CES, like fresh CES, consisted of three to four well-maintained epidermal layers, as shown by the expression of keratins, involucrin, and p63. There were no differences in the epidermal layer or protein expression between L-CES and F-CES, and both CES were comparable to fresh CES. TGF-α, EGF, VEGF, IL-1α, and MMPs were detected in L-CES at levels similar to those in F-CES. In a mouse study, wounds treated with L-CES or F-CES completely healed at least 4 days faster than untreated wounds. CES-treated wounds completely healed by day 10, while the untreated wounds did not heal by day 14. Masson’s trichrome staining showed that collagen deposition in the CES-treated wounds was highly increased in the dermis of the wound center compared to that in the control wounds. Thus, this study demonstrates that L-CES is as clinically effective as F-CES for wound treatment.

2010-01-01

Cellulose synthase catalytic subunit genes, CesA, have been discovered in several higher plant species, and it has been shown that the CesA gene family has multiple members. HVR2 fragment of these genes determine the class specificity of the CESA protein and its participation in the primary or secondary cell wall synthesis. The aim of this study was development of specific and degenerated primers to flax CesA gene fragments leading to obtaining the class specific HVR2 region of the gene. Two pairs of specific primers to the certain fragments of CesA-1 and CesA-6 genes and one pair of degenerated primers to HVR2 region of all flax CesA genes were developed basing on comparison of six CesA EST sequences of flax and full cDNA sequences of Arabidopsis, poplar, maize and cotton plants, obtained from GenBank. After amplification of flax cDNA, the bands of expected size were detected (201 and 300 b.p. for the CesA-1 and CesA-6, and 600 b.p. for the HVR2 region of CesA respectively). The developed markers can be used for cloning and sequencing of flax CesA genes, identifying their number in flax genome, tissue and stage specificity.

Full Text Available OBJECTIVE: To establish the reliability and validity of a shortened (10-item depression scale used among HIV-positive patients enrolled in the Drug Treatment Program in British Columbia, Canada. METHODS: The 10-item CES-D (Center for Epidemiologic Studies Depression Scale was examined among 563 participants who initiated antiretroviral therapy (ART between August 1, 1996 and June 30, 2002. Internal consistency of the scale was measured by Cronbach's alpha. Using the original CES-D 20 as primary criteria, comparisons were made using the Kappa statistic. Predictive accuracy of CES-D 10 was assessed by calculating sensitivity, specificity, positive predictive values and negative predictive values. Factor analysis was also performed to determine if the CES-D 10 contained the same factors of positive and negative affect found in the original development of the CES-D. RESULTS: The correlation between the original and the shortened scale is very high (Spearman correlation coefficient  =0.97 (P<0.001. Internal consistency reliability coefficients of the CES-D 10 were satisfactory (Cronbach α=0.88. The CES-D 10 showed comparable accuracy to the original CES-D 20 in classifying participants with depressive symptoms (Kappa=0.82, P<0.001. Sensitivity of CES-D 10 was 91%; specificity was 92%; and positive predictive value was 92%. Factor analysis demonstrates that CES-D 10 contains the same underlying factors of positive and negative affect found in the original development of the CES-D 20. CONCLUSION: The 10-item CES-D is a comparable tool to measure depressive symptoms among HIV-positive research participants.

PRINCIPLES OF THE EUROPEAN ADMINISTRATIVE SPACE AND THEIR IMPACT ON PERFORMANCE IN PUBLIC ORGANIZATIONS

Directory of Open Access Journals (Sweden)

Alexandra Ema Cioclea

2012-09-01

Full Text Available The European Union is interested in ensuring that each national administration offers comparable administrative capacity through quality of public services and professionalism from the civil servants. At the same time, the European states are characterised by long and varied institutional histories, with different trajectories in their evolution. That is why, public administration structures and regulations vary among the Member States and a set of common principles can guide them towards administrative convergence and performance. This paper aims to analyze the shared principles of a common European Administrative Space and also to address the link between these principles and the performance of public institutions from a managerial point of view. The study is based on review and analysis of academic research, government documents and personal perspectives, extracting and linking key findings from existing research and practice. The paper argues that managerial theories on performance are compatible with public administration organizations and some of the criteria are common to those promoted by the principles of the European Administrative Space.

Two alleles of the AtCesA3 gene in Arabidopsis thaliana display intragenic complementation.

Science.gov (United States)

Pysh, Leonard D

2015-09-01

Cellulose is the most abundant biomolecule on the planet, yet the mechanism by which it is synthesized by higher plants remains largely unknown. In Arabidopsis thaliana (L.) Heynh, synthesis of cellulose in the primary cell wall requires three different cellulose synthase genes (AtCesA1, AtCesA3, and AtCesA6-related genes [AtCesA2, AtCesA5, and AtCesA6]). The multiple response expansion1 (mre1) mutant contains a hypomorphic AtCesA3 allele that results in significantly shorter, expanded roots. Crosses between mre1 and another allele of AtCesA3 (constitutive expression of VSP1, cev1) yielded an F1 with roots considerably longer and thinner than either parent, suggesting intragenic complementation. The F2 generation resulting from self-crossing these F1 showed three different root phenotypes: roots like mre1, roots like cev1, and roots like the F1. The segregation patterns of the three root phenotypes in multiple F2 and F3 generations were determined. Multiple characteristics of the roots and shoots were analyzed both qualitatively and quantitatively at different developmental stages, both on plates and on soil. The trans-heterozygous plants differed significantly from the parental mre1 and cev1 lines. The two alleles display intragenic complementation. A classic genetic interpretation of these results would suggest that cellulose synthesis requires homo-multimerization of cellulose synthase monomers. © 2015 Botanical Society of America.

The European Space Agency (ESA) has twenty Member States with a variety of strategic priorities and governance structures regarding their space activities. A number of countries engage in space activities exclusively though ESA, while others have also their own national space programme. Some consider ESA as their prime space agency and others have additionally their own national agency with respective programmes. The main objective of this paper is to provide an up-to date overview and a holistic assessment of strategic priorities and the national space governance structures in 20 ESA Member States. This analysis and assessment has been conducted by analysing the Member States public documents, information provided at ESA workshop on this topic and though unstructured interviews. The paper is structured to include two main elements: priorities and trends in national space strategies and space governance in ESA Member States. The first part of this paper focuses on the content and analysis of the national space strategies and indicates the main priorities and trends in Member States. The priorities are categorised with regards to technology domains, the role of space in the areas of sustainability and the motivators that boost engagement in space. These vary from one Member State to another and include with different levels of engagement in technology domains amongst others: science and exploration, navigation, Earth observation, human space flight, launchers, telecommunications, and integrated applications. Member States allocate a different role of space as enabling tool adding to the advancement of sustainability areas including: security, resources, environment and climate change, transport and communication, energy, and knowledge and education. The motivators motivating reasoning which enhances or hinders space engagement also differs. The motivators identified are industrial competitiveness, job creation, technology development and transfer, social benefits

2016-10-01

Method CES (collisional electron spectroscopy), patented in Russia, the USA, Japan, China, Germany and Britain, allows to analyze the gaseous mixtures using electron spectroscopy under high pressures up to atmospheric without using vacuum. The design of VUV photoionization detector was developed based on this method. Such detector is used as a portable gas analyzer for continuous personal bio-medical monitoring. This detector measures energy of electrons produced in ionization with resonance photons, whose wavelength situated in the vacuum ultraviolet (VUV). Nowadays, micro plasma source of such photons on resonant line of Kr with energy of 10,6 eV is developed. Only impurities are ionized and detected by the VUV-emission, meanwhile the main components of air stay neutral that reduces background signal and increases the sensibility along with accuracy. The experimental facilities with VUV photoionization sensors CES are constructed with the overall sizes about 10*10*1 mm. The watt consumption may comprise less than 1W. Increase of electrometer amplifier's sensibility and more high-aperture construction are used today to increase the sensibility of CES-detectors. The wide range of detectable molecules and high sensitivity allow the development of portable device, which can become the base of the future preventive medicine.

Space and the complexity of European rules and policies: The common projects Galileo and GMES—precedence for a new European legal approach?

Science.gov (United States)

Froehlich, Annette

2010-04-01

The two European flagship space projects, Galileo and GMES, clearly show that the current existing legal rules of the two organisations involved (European Union and European Space Agency) are not compatible. Moreover, it is quite impossible to implement a common project if every single organisation insists on the application of its own rules strictu sensu. Nevertheless, due to the political desire to advance these projects rapidly and to make them a success, legal obstacles were to be overcome. Consequently, recently concluded agreements between ESA and the EU-Commission concerning the financial and governmental matters of the Galileo and GMES implementation feature a new approach to cooperation between these two organisations. However, the question remains if they can be taken as precedence for a future institutionalised cooperation? It follows that the agreements have to be analysed in order to understand how a mutually acceptable agreement was reached despite the disparity in the rules of both organisations. In this regard, especially the financial decision agreement concerning Galileo in December 2007 shows a very interesting and unique way in applying EU-competition law. In the same way, the GMES-Delegation Agreement of spring 2008 is a good example of how two different legal systems can be applied to make a project success. Additionally, the reasons and arguments of both organisations have to be considered, especially once the Treaty of Lisbon will be in force. As these two main projects of the European Space Policy are characterized by the desire for a successful European cooperation, they can be regarded as an important step forward for a new legal approach. A new system emerges which could be taken into consideration for further common projects undertaken by ESA and the EU.

The "Center of Epidemiologic Studies - Depression scale" (CES-D) is a well-known screening tool for depression. Until now the criterion validity of the German version of the CES-D was not investigated in a sample of the adult general population. 508 study participants of the Austrian general population completed the CES-D. ICD-10 diagnoses were established by using the Schedules for Clinical Assessment in Neuropsychiatry (SCAN). Receiver Operating Characteristics (ROC) analysis was conducted. Possible gender differences were explored. Overall discriminating performance of the CES-D was sufficient (ROC-AUC 0,836). Using the traditional cut-off values of 15/16 and 21/22 respectively the sensitivity was 43.2 % and 32.4 %, respectively. The cut-off value developed on the basis of our sample was 9/10 with a sensitivity of 81.1 % und a specificity of 74.3 %. There were no significant gender differences. This is the first study investigating the criterion validity of the German version of the CES-D in the general population. The optimal cut-off values yielded sufficient sensitivity and specificity, comparable to the values of other screening tools. © Georg Thieme Verlag KG Stuttgart · New York.

Artist's impression of the JWST Credits: ESA Artist's impression of the JWST An artist's impression of the selected design for the JWST spacecraft. Northrop Grumman and Ball Aerospace are the prime contractors for JWST. Observing the first light, the James Webb Space Telescope (JWST) will help to solve outstanding questions about our place in the evolving Universe. MIRI, the Mid-Infrared Instrument, is one of the four instruments on board the JWST, the mission scheduled to follow on the heritage of Hubble in 2011. MIRI will be built in cooperation between Europe and the United States (NASA), both equally contributing to its funding. MIRI’s optics, core of the instrument, will be provided by a consortium of European institutes. According to this formal agreement, ESA will manage and co-ordinate the whole development of the European part of MIRI and act as the sole interface with NASA, which is leading the JWST project. This marks a difference with respect to the previous ESA scientific missions. In the past the funding and the development of the scientific instruments was agreed by the participating ESA Member States on the basis of purely informal arrangements with ESA. In this case, the Member States involved in MIRI have agreed on formally guaranteeing the required level of funding on the basis of a multi-lateral international agreement, which still keeps scientists in key roles. Over the past years, missions have become more complex and demanding, and more costly within an ever tighter budget. They also require a more and more specific expertise which is spread throughout the vast European scientific community. As a result, a new management procedure for co-ordination of payload development has become a necessity to

The Center for Epidemiologic Studies Depression Scale (CES-D: Is It Suitable for Use with Older Adults?

Górkiewicz Maciej

2015-12-01

Full Text Available With the aim of verifying the suitability of the CES-D scale for use in long-term care institutions for older adults, the CES-D questionnaire was used to collect patient-reported assessments, and two well-known psychometric instruments – the Hospital Anxiety and Depression Scale (HADS and the Barthel Index of Abilities of Daily Living – were used to collect nurse-reported assessments, based on observations of patients’ behaviours. With regard to possible frequent cases of cognitive impairment and/or insufficient motivation to give sensible responses to CES-D questions, the patient-reported responses were collected from patients during one-on-one sessions with a nurse. The reliability, concurrent validity, and the trustworthiness of the obtained data were supported with proper values of the Cronbach’s alpha coefficient, 0.70 < alpha < 0.85, with significant correlation between CES-D and HADS-Depression, R = 0.50, p < 0.001, and with significant correlation between scores of particular CES-D items vs. final CES-D evaluations of depression, proved by significance p < 0.001 for 18 of 20 CES-D items. These findings supported the effectiveness of the one-on-one session methodology in questionnaire surveys for older adults. The postulation that cases of self-reported depression included somewhat different information about the patient than nurse-reported depression concerning the same patient was supported with the evidence that, in spite of the significant correlation between the Barthel Index and HADS-Depression, R = −0.17, p = 0.016, and in spite of the significant correlation between CES-D and HADS-Depression, the correlation between the Barthel Index and CES-D, equal to R = −0.08 was insignificant at p = 0.244. The findings of this study, considered jointly, support the valuableness of the CES-D scale for use in one-on-one surveys for older adults.

The CES-D is a commonly used self-report assessment for depressive symptomatology. However, its psychometric properties have not been evaluated in Fiji. This study aims to evaluate the reliability and validity of English language and Fijian vernacular versions in ethnic Fijian adolescent schoolgirls. As part of the HEALTHY Fiji study, ethnic Fijian female adolescents (N = 523) completed the CES-D. Participants selected to respond in English or the local vernacular. Reliability (internal consistency, item-total score correlation, and test-retest estimates), validity (associations with other proxies for depression) and factor structure were assessed. Evaluations considered differences between language versions. In this sample, the CES-D had a Cronbach's α of 0.81 and item-total score correlation coefficients ranged between 0.2 and 0.63. One week test-retest reliability (ICC(2)) was 0.57. CES-D scores were higher among individuals who endorsed feelings of depression and suicidality compared to those who did not. ROC analyses of the CES-D versus binary depression and suicidality variables produced AUCs around 0.70 and did not support a discrete cut-off for significant disturbance. Findings were similar across the two language groups. The CES-D has acceptable reliability and validity among ethnic Fijian female adolescents in English and in the Fijian vernacular language. Findings support its utility as a dimensional measure for depressive symptomatology in this study population. Further examination of its clinical utility for case finding for depression in Fijian school-based and community populations is warranted. © The Author(s) 2013.

The place of polish in the multilingual space of the European Union

2015-03-01

Full Text Available The article studies the position of the Polish language in the multilingual space of the European Union and determines the key factors which facilitate its gaining popularity and spreading in Europe. A large territory and population determine the significant presence of Polish in the European Union. Intense economic development facilitates popularization of learning and using Polish in the business medium, however, English was and still remains the dominating language of business. Active work of the state on improving the reputation of the country abroad, civilizational (value­based unity with other nations of the EU, favorable geographical position, common Indo­European roots of Germanic, Romanic and Slavonic  languages as well as usage of the Latin type create favorable conditions for the development and popularization of Polish on the territory of the EU. The article also mentions a number of concerns, which are rooted in the historical past of a dependent or semi­dependent existence of the Polish people, namely, the existence of the Polish and culture in the shade of German and Russian culture space, the negative international image of modern Poland, which was formed at the beginning of the 1990­s, the low level of Europeans’ familiarization with the Polish culture, absence of popularity and economic necessity of learning Polish abroad.

NEREUS- Network of European Regions Using Space - an initiative of regions to spread the use and understanding of space technologies across Europe (Roya Ayazi, Secretary General NEREUS nereus.bruxelles@euroinbox.com) NEREUS currently unites 25 European regions and 39 Associate Members with the common objective to spread the use and understanding of space technologies across Europe for the benefit of regions and their citizens. As voice of European Regions, NEREUS serves as an advocate for the regions in matters of space uses and also as a direct channel to the regional users of space technologies (such as local authorities, SMEs, universities and research institutes and citizens). EO/GMES, Global Satellite Navigation and Telecommunication are identified by the NEREUS Political Charta as core areas of cooperation. NEREUS holds the view that broad societal awareness and involvement is vital to fully exploit Euope's space systems. Understanding the potentials of Copernicus and EGNOS/Galileo is in the first place an essential step for the development of the downstream sector. Therefore NEREUS makes special efforts to contribute with numerous network activities to communicate and promote the added value of space uses for public policies but also as valuable new business opportunities. In economic terms space uses are suited to stimulate economic growth and innovation dynamics at regional level. The network community produced several illustrative communication tools (publications, video, web-based tools, mobile NEREUS-exhibition) portraying examples how regions already use space systems and the concrete benefits for the citizens. Most of the NEREUS-publications and video are online: www.nereus-regions.eu. Pooling a considerable wealth of capabilities and expertise, the network offers its members a dynamic platform to collaborate and share experiences and knowledge inter regionally. But these tools were not only the outcome of an intensive regional collaboration but

Many epidemiological studies have found that people living in environments with more green space report better physical and mental health than those with less green space. However, the association between visits to green space and mental health has seldom been studied. The current study explored the associations between time spent in green spaces by purposeful visits and perceived mental health and vitality in four different European cities, and to what extent gender, age, level of education, attitude towards nature and childhood nature experience moderate these associations. Data was gathered using a questionnaire administered in four European cities (total n=3748). Multilevel analyses showed significant positive associations between time spent visiting green spaces and mental health and vitality in the pooled data, as well as across the four cities. Significant effect modification was found for level of education and childhood nature experience. The findings confirm the hypothesis that more time spent in green space is associated with higher scores on mental health and vitality scales, independent of cultural and climatic contexts.

Europeanization in VET Policy as a Process of Reshaping the Educational Space

Directory of Open Access Journals (Sweden)

Krista Loogma

2016-04-01

Full Text Available The EU represents a transforming educational space, where national and supranational boundaries in educational governance are becoming blurred. The EU has become an  important actor in educational governance and an important arena for policy learning and transfer. This paper explores how the process of reshaping the educational space manifests itself in the process of the Europeanization of VET policy in the case of Estonia. In Estonia, this process was followed by the growth of executive VET institutions and has developed from rather uncritical initial policy transfer to more active learning from the EU, although conformism can still be seen in cases of the introduction of standardizing policy tools.

The common objectives of the European Nordic countries and the role of space

Lehnert, Christopher; Giannopapa, Christina; Vaudo, Ersilia

2016-11-01

The European Space Agency (ESA) has twenty two Member States with common goals of engaging in European space activities. However, the various Member States have a variety of governance structures, strategic priorities regarding space and other sectorial areas depending on their cultural and geopolitical aspirations. The Nordic countries, namely Denmark, Finland, Norway and Sweden, have similarities which result often in common geopolitical and cultural aspects. These in turn shape their respective priorities and interests in setting up their policies in a number of sectorial areas like shipping and fisheries, energy, immigration, agriculture, security and defence, infrastructures, climate change and the Arctic. Space technology, navigation, earth observation, telecommunication and integrated applications can assist the Nordic countries in developing, implementing and monitoring policies of common interest. This paper provides an in-depth overview and a comprehensive assessment of these common interests in policy areas where space can provide support in their realisation. The first part provides a synthesis of the Nordic countries respective priorities through analysing their government programmes and plans. The priorities are classified according to the six areas of sustainability: energy, environment and climate change, transport, knowledge and innovation, natural resources (fisheries, agriculture, forestry, mining, etc), and security and external relations. Although the national strategies present different national perspectives, at the same time, there are a number of similarities when it comes to overall policy objectives in a number of areas such as the Arctic and climate change. In other words, even though the Arctic plays a different role in each country's national context and there are clear differences as regards geography, access to resources and security policies, the strategies display common general interest in sustainable development and management of

Full Text Available Cellulose is the primary determinant of mechanical strength in plant tissues. Late-season lodging is inversely related to the amount of cellulose in a unit length of the stem. Wheat is the most widely grown of all the crops globally, yet information on its CesA gene family is limited. We have identified 22 CesA genes from bread wheat, which include homoeologs from each of the three genomes, and named them as TaCesAXA, TaCesAXB or TaCesAXD, where X denotes the gene number and the last suffix stands for the respective genome. Sequence analyses of the CESA proteins from wheat and their orthologs from barley, maize, rice, and several dicot species (Arabidopsis, beet, cotton, poplar, potato, rose gum and soybean revealed motifs unique to monocots (Poales or dicots. Novel structural motifs CQIC and SVICEXWFA were identified, which distinguished the CESAs involved in the formation of primary and secondary cell wall (PCW and SCW in all the species. We also identified several new motifs specific to monocots or dicots. The conserved motifs identified in this study possibly play functional roles specific to PCW or SCW formation. The new insights from this study advance our knowledge about the structure, function and evolution of the CesA family in plants in general and wheat in particular. This information will be useful in improving culm strength to reduce lodging or alter wall composition to improve biofuel production.

2009-02-01

Full Text Available Abstract Background Depression is common in rheumatoid arthritis (RA, however reported prevalence varies considerably. Two frequently used instruments to identify depression are the Center for Epidemiological Studies Depression (CES-D scale, and the Hospital Anxiety and Depression Scale (HADS. The objectives of this study were to test if the CES-D and HADS-D (a satisfy current modern psychometric standards for unidimensional measurement in an early RA sample; (b measure the same construct (i.e. depression; and (c identify similar levels of depression. Methods Data from the two scales completed by patients with early RA were fitted to the Rasch measurement model to show that (a each scale satisfies the criteria of fit to the model, including strict unidimensionality; (b that the scales can be co-calibrated onto a single underlying continuum of depression and to (c examine the location of the cut points on the underlying continuum as indication of the prevalence of depression. Results Ninety-two patients with early RA (62% female; mean age = 56.3, SD = 13.7 gave 141 sets of paired CES-D and HAD-D data. Fit of the data from the CES-D was found to be poor, and the scale had to be reduced to 13 items to satisfy Rasch measurement criteria whereas the HADS-D met model expectations from the outset. The 20 items combined (CES-D13 and HADS-D satisfied Rasch model expectations. The CES-D gave a much higher prevalence of depression than the HADS-D. Conclusion The CES-D in its present form is unsuitable for use in patients with early RA, and needs to be reduced to a 13-item scale. The HADS-D is valid for early RA and the two scales measure the same underlying construct but their cut points lead to different estimates of the level of depression. Revised cut points on the CES-D13 provide comparative prevalence rates.

Full Text Available Les eaux de surface sont prélevées pour divers usages industriels, parmi lesquels la production d'énergie électrique représente une large part. Dans les circuits d'eau brute se fixent de nombreuses espèces d'organismes aquatiques, qui perturbent le fonctionnement des installations et sont susceptibles d'entraîner l'indisponibilité de certaines d'entre elles. Dans certains cas, l'irruption de nouvelles espèces pose un problème grave à l'industrie. L'introduction de deux espèces de moules zébrées (genre Dreissena dans les Grands Lacs américains, puis leur extension progressive vers le sud des États-Unis au cours des dernières années, se chiffre par un dommage pour l'industrie estimé à cinq milliards de dollars par an en 2000. L'impact écologique de la moule zébrée en Amérique du Nord a fait l'objet de nombreux travaux ; dans la phase d'extension rapide de l'espèce, il semble significatif. En Europe, la moule zébrée constitue aussi une menace pour les circuits industriels ; c'est pourquoi cette espèce a fait l'objet de nombreuses études, notamment en France sur la Seine, le Rhône et la Moselle. Deux nouvelles espèces invasives sont récemment apparues dans les cours d'eau européens : il s'agit du clam asiatique Corbicula fluminea et d'un amphipode : Corophium curvispinum. Elles s'ajoutent à la liste faunistique des organismes observés dans les circuits de centrales thermiques installées sur les cours d'eau français : spongiaires, hydraires, bryozoaires, mollusques. Pour assurer la disponibilité des circuits, il faut pouvoir contrôler le développement de ces espèces ; ce qui implique une connaissance approfondie de leur biologie et de leur écologie. Les méthodes de lutte actuellement mises en oeuvre au plan industriel, ou qui sont à l'étude, sont brièvement passées en revue.

The primary aim was to examine the depressive symptom structure of Mainland China adolescents using the Center for Epidemiologic Studies Depression Scale (CES-D). Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were simultaneously conducted to determine the structure of the CES-D in a large scale, representative adolescent samples recruited from Mainland China. Multigroup CFA (N = 5059, 48% boys, mean = 16.55±1.06) was utilized to test the factorial invariance of the depressive symptom structure, which was generated by EFA and confirmed by CFA across gender. The CES-D can be interpreted in terms of 3 symptom dimensions. Additionally, factorial invariance of the new proposed model across gender was supported at all assuming different degrees of invariance. Mainland Chinese adolescents have specific depressive symptom structure, which is consistent across gender. © 2013 Wiley Periodicals, Inc.

Taking part in space activities and participating in the development and growth of space project has now become an undeniable reality. Thanks to academic institutions and outreach activities space enthusiasts can engage in numerous and diverse yet unique opportunities. The ESA Outreach Office sees students of every background taking part in its activities. This unique mixture of students of diverse nationalities enthusiastically co-operating ensures the program's interdisciplinarity. The added value of such an environment to the programs is significant and must not be forgotten. The friendship that blossom, and lose with which cultural and language barriers are overcome during the time spent working on the projects offered to university student and young professionals are invaluable. The purpose of this abstract is to give our perspective to the space community and to the general public on the importance of developing a space culture. The academic value of the space research projects mainly in which the authors have participated, the importance of such projects for the future of European relations and personal and social development through experience of international teams are topics that will be addressed. The activities discussed are : Attending sessions of congresses around the world, making contacts of major companies and players in the space sector, dealing of topics such as space engineering, policy and law, life sciences, business and finance, satellite applications, the exhilaration of floating in zero-g, the interdisciplinary, international and intercultural approach, the chance of quickly learning about many new concepts are just some of the marvellous experiences and opportunities that these programs offer. Reaching out to the general public is the second purpose of these unique activities.Images, photos and reports can seep into every house thanks to the great instrument that is the media, thus informing almost everyone about the activities and

Tromsø Geophysical Observatory (TGO) is responsible for making and maintaining long time-series of geomagnetic measurements in Norway. TGO is currently operating 3 geomagnetic observatories and 11 variometer stations from southern Norway to Svalbard . Data from these 14 locations are acquired, processed and made available for the user community in near real-time. TGO is participating in several European Union (EU) and European Space Agency (ESA) space weather related projects where both near real-time data and derived products are provided. In addition the petroleum industry is benefiting from our real-time data services for directional drilling. Near real-time data from TGO is freely available for non-commercial purposes. TGO is exchanging data in near real-time with several institutions, enabling the presentation of near real-time geomagnetic data from more than 40 different locations in Fennoscandia and Greenland. The open exchange of non real-time geomagnetic data has been successfully going on for many years through services such as the world data center in Kyoto, SuperMAG, IMAGE and SPIDR. TGO's vision is to take this one step further and make the exchange of near real-time geomagnetic data equally available for the whole community. This presentation contains an overview of TGO, our activities and future aims. We will show how our near real-time data are presented. Our contribution to the space weather forecasting and nowcasting effort in the EU and ESA will be presented with emphasis on our real-time auroral activity index and brand new auroral activity monitor and electrojet tracker.

Suh, Hanna; van Nuenen, Marieke; Rice, Kenneth G

2017-10-01

Detecting psychological distress among international students can be challenging given diverse languages, cultural backgrounds, and lack of refined measurement properties of measures tailored to international students. Despite the challenges, ensuring that a psychological distress measure works effectively has considerable potential value for assessment purposes. The current study evaluates the measurement properties of a short 10-item version of Radloff's Center for Epidemiologic Studies Depression Scale (CES-D). Grounded in long-standing evidence on gender differences in depressive symptoms, specific attention was given to examining measurement invariance of the CES-D Short-form across women and men. Based on a large, two-cohort sample of international students ( N = 468), and through multiple analyses evaluating factor structure and measurement invariance, we derived an even briefer, seven-item single-factor form of the CES-D (CES-D Short-form International) that can be used with international students.

Cross-Cultural Issues of Intra- and Inter-Organisational Cooperation in Space Operations: A Survey Study with Ground Personnel of the European Space Agency

Today's space operations often involve close co-working of people with different ethnical, professional and organizational backgrounds. The aim of the study was to examine the implications of cultural diversity for efficient collaboration within the European Space Agency (ESA), and between ESA employees and representatives from other agencies. Methods: A web-based survey was answered by 905 employees at the European Astronaut Centre and at the European Space Technology Centre. An adapted version of the Flight Management Attitude Questionnaire by Helmreich and Merrit was used. Personnel were also asked about interpersonal and operational issues that interfered with efficient co-working within ESA and in relation to other space agencies. Results: Collaboration within ESA: A descriptive analysis was conducted of the rank orders of challenges perceived by members of different nationalities (the Netherlands (N=68), German (N=138), Italian (N=135), French (N=124), British (N=84) and Scandinavian (27).Rank orders show a surprisingly uniformity across nationalities. Most respondents perceived differences in the preferred leadership style as the main challenge for co-working in multi-national groups followed by differences in dealing with conflicts and misunderstandings. In contrast communication problems due different languages and differences in non-verbal behaviour, as well as differences in gender stereotypes were among the lowest rated issues. However, Scandinavian respondents showed a different pattern from other nationalities. Collaboration between agencies: The most significant issues reported to interfere with the efficiency of inter-agency collaboration varied. Most difficulties were reported in relation to clarity of communication, insufficient sharing of task related information, understanding the process of decision making in partner organization, and authoritarian leadership style in the partner organization Conclusion: Cultural differences in leadership and

Full Text Available Introdução: A proporção de partos cesarianos no Brasil está muito além da preconizada pela Organização Mundial da Saúde, o mesmo ocorrendoem um Hospital Universitário de Porto Alegre, sul do Brasil. A taxa de cesáreas é considerada um indicador poderoso na avaliação da qualidade da assistência perinatal. Nosso objetivo foi analisar o padrão dos partos cesarianos e normais em um hospital universitário no período de2004 a 2012 quanto à média de permanência, faixa etária da parturiente, taxa de infecção relacionada ao parto, tipo de pagador e idade gestacional. Métodos: Estudo de coorte retrospectivo, observacional, com dados coletados no Sistema de Indicadores de Gestão (IG de um Hospital Universitário, abrangendo o período de2004 a 2012. Resultados: A taxa de cesárea no hospital universitário nos anos analisados foi em média 33,21%. Em relação às cesarianas realizadas nesta instituição durante o período em estudo, observou-se que: há uma maior prevalência de cesáreas em mulheres acima de 40 anos, ocorreu um crescimento de partos cesarianos pré-termo, a média de permanência e taxa de infecção foram superiores em relação às mulheres submetidas ao parto vaginal, e houve predomínio de cesarianas na saúde suplementar quando comparada ao Sistema Único de Saúde. Conclusões: As elevadas taxas de cesárea no hospital universitário, embora acima do recomendado pela OMS, são justificadas por se tratar de um hospital terciário e estão em conformidade com o padrão observado no país.

In 2005, the EU made the strategic choice of developing a space-based programme, called Global Monitoring for Environment and Security (GMES). GMES is an independent Earth monitoring initiative led by the European Union and carried out in partnership with the Member States and the European Space Agency (ESA). Its primary objective is to provide information services that give access to accurate data and information in the field of the environment and security and are tailored to the needs of users. However, at the regional level, stakeholders are often not aware about the potential benefits of services Europe's GMES initiative can provide; yet Europe's ca. 350 regions represent a large reservoir of potential GMES users where GMES services can add value to existing services. Refining data, products and services from global GMES services in the various domains (i.e. land, marine, atmosphere, emergency response, security and climate change), GMES downstream services may be customised to individual user needs, many of which are to be found a the regional level. Within a number of regions, links between the different types of stakeholders have grown over the years. Often, individual actors have developed inter-regional links but their linkage is in most cases not formalised. When looking at the European scale, that overall awareness of GMES downstream opportunities is still very low with respect to the potential benefits regions could draw from a wider participation. However, being aware of the potential of GMES, of the important role they can play and of the need for exchanging experiences, pioneering Local and Regional Authorities (LRAs) intending to retrieve benefit from space technologies, including GMES, have now started to collaborate within structured networks, NEREUS being the most advanced example. The logically next step is that LRAs engage in a dialogue with service-industry and European decision-makers to maximize the benefits from these innovative tools

This study examines the relationship between neighbourhood green space, the neighbourhood social environment (social cohesion, neighbourhood attachment, social contacts), and mental health in four European cities. The PHENOTYPE study was carried out in 2013 in Barcelona (Spain), Stoke-on-Trent (United Kingdom), Doetinchem (The Netherlands), and Kaunas (Lithuania). 3771 adults living in 124 neighbourhoods answered questions on mental health, neighbourhood social environment, and amount and quality of green space. Additionally, audit data on neighbourhood green space were collected. Multilevel regression analyses examined the relation between neighbourhood green space and individual mental health and the influence of neighbourhood social environment. Mental health was only related to green (audit) in Barcelona. The amount and quality of neighbourhood green space (audit and perceived) were related to social cohesion in Doetinchem and Stoke-on-Trent and to neighbourhood attachment in Doetinchem. In all four cities, mental health was associated with social contacts. Neighbourhood green was related to mental health only in Barcelona. Though neighbourhood green was related to social cohesion and attachment, the neighbourhood social environment seems not the underlying mechanism for this relationship.

The European space suit, a design for productivity and crew safety

Science.gov (United States)

Skoog, A. Ingemar; Berthier, S.; Ollivier, Y.

In order to fulfil the two major mission objectives, i.e. support planned and unplanned external servicing of the COLUMBUS FFL and support the HERMES vehicle for safety critical operations and emergencies, the European Space Suit System baseline configuration incorporates a number of design features, which shall enhance the productivity and the crew safety of EVA astronauts. The work in EVA is today - and will be for several years - a manual work. Consequently, to improve productivity, the first challenge is to design a suit enclosure which minimizes movement restrictions and crew fatigue. It is covered by the "ergonomic" aspect of the suit design. Furthermore, it is also necessary to help the EVA crewmember in his work, by giving him the right information at the right time. Many solutions exist in this field of Man-Machine Interface, from a very simple system, based on cuff check lists, up to advanced systems, including Head-Up Displays. The design concept for improved productivity encompasses following features: • easy donning/doffing thru rear entry, • suit ergonomy optimisation, • display of operational information in alpha-numerical and graphical from, and • voice processing for operations and safety critical information. Concerning crew safety the major design features are: • a lower R-factor for emergency EVA operations thru incressed suit pressure, • zero prebreath conditions for normal operations, • visual and voice processing of all safety critical functions, and • an autonomous life support system to permit unrestricted operations around HERMES and the CFFL. The paper analyses crew safety and productivity criteria and describes how these features are being built into the design of the European Space Suit System.

2007-01-01

Background The aim of this study was to test the internal validity of the total Center for Epidemiologic Studies-Depression (CES-D) scale using Rasch analysis in a rheumatoid arthritis (RA) population. Methods CES-D was administered to 157 patients with RA over three time points within a 12 month period. Rasch analysis was applied using RUMM2020 software to assess the overall fit of the model, the response scale used, individual item fit, differential item functioning (DIF) and person separation. Results Pooled data across three time points was shown to fit the Rasch model with removal of seven items from the original 20-item CES-D scale. It was necessary to rescore the response format from four to three categories in order to improve the scale's fit. Two items demonstrated some DIF for age and gender but were retained within the 13-item CES-D scale. A new cut point for depression score of 9 was found to correspond to the original cut point score of 16 in the full CES-D scale. Conclusion This Rasch analysis of the CES-D in a longstanding RA cohort resulted in the construction of a modified 13-item scale with good internal validity. Further validation of the modified scale is recommended particularly in relation to the new cut point for depression. PMID:17629902

También se observó la velocidad de recuperación de la clorofila en plantas cloróticas de cacao y café, al agregarles cantidades crecientes de hierro, y el efecto de dicha recuperación sobre el desarrollo radical. Además, se estudió el grado de absorción y movilización de Fe50 en plantas de cacao, y el efecto de distintas dosis de hierro en el crecimiento de raíces aisladas cacao, café y fríjol. Las plantas fueron cultivadas en el invernadero en solución HoagIand N° 2 sin Fe y las raíces para cultivo se obtuvieron de semillas germinadas en el laboratorio. Se usaron plantas de cacao del clon uf 668 de 3 meses y de café (variedad caturra con la misma edad.

Las adiciones de este elemento se hicieron cuando las plantas mostraban síntomas característicos de su deficiencia. Hubo una recuperación casi total de la clorosis y tanto el volumen como la longitud radical aumentaron con las aplicaciones crecientes de hierro, aunque la longitud relativa de los tallos mostró una tendencia decreciente. En las hojas de cacao se presentó una acumulación del Fe y su movilización hacia los demás órganos de la planta fue lenta y en proporción reducida en relación con el total absorbido. Igual cosa sucedió con el Fe50 suministrado a las raíces. No se pudieron observar los efectos del Fe en el crecimiento de raíces aisladas de cacao, café y fríjol, pues el desarrollo fue muy reducido, debido a que la rápida oxidación de los tejidos (al separar aquéllas del resto de la planta redujo la viabilidad a unos pocos días.

Space experiments provide a unique opportunity to advance our knowledge of how plants respond to the space environment, and specifically to the absence of gravity. The European Modular Cultivation System (EMCS) has been designed as a dedicated facility to improve and standardise plant growth in the International Space Station (ISS). The EMCS is equipped with two centrifuges to perform experiments in microgravity and with variable gravity levels up to 2.0 g. Seven experiments have been performed since the EMCS was operational on the ISS. The objectives of these experiments aimed to elucidate phototropic responses (experiments TROPI-1 and -2), root gravitropic sensing (GRAVI-1), circumnutation (MULTIGEN-1), cell wall dynamics and gravity resistance (Cell wall/Resist wall), proteomic identification of signalling players (GENARA-A) and mechanism of InsP3 signalling (Plant signalling). The role of light in cell proliferation and plant development in the absence of gravity is being analysed in an on-going experiment (Seedling growth). Based on the lessons learned from the acquired experience, three preselected ISS experiments have been merged and implemented as a single project (Plant development) to study early phases of seedling development. A Topical Team initiated by European Space Agency (ESA), involving experienced scientists on Arabidopsis space research experiments, aims at establishing a coordinated, long-term scientific strategy to understand the role of gravity in Arabidopsis growth and development using already existing or planned new hardware. © 2014 German Botanical Society and The Royal Botanical Society of the Netherlands.

The European Space Agency's (ESA) Planetary Science Archive (PSA), which can be accessed at http://archives.esac.esa.int/psa, provides public access to the archived data of Europe's missions to our neighboring planets. These datasets are compliant with the Planetary Data System (PDS) standards. Recently, a new interface has been released, which includes upgrades to make PDS4 data available from newer missions such as ExoMars and BepiColombo. Additionally, the PSA development team has been working to ensure that the legacy PDS3 data will be more easily accessible via the new interface as well. In addition to a new querying interface, the new PSA also allows access via the EPN-TAP and PDAP protocols. This makes the PSA data sets compatible with other archive-related tools and projects, such as the Virtual European Solar and Planetary Access (VESPA) project for creating a virtual observatory.

Rodríguez, José R; Rodríguez, Rosa Janet; Disdier, Orville M

2007-03-01

The prevalence of diabetes mellitus in Puerto Ricans has been identified and reported as being disproportionately higher as compared to other metabolic pathologies. Recently, diabetes has been identified as the third cause of mortality in Puerto Rico (Puerto Rico Health Department, Vital Statistics Annual Report, 1999-2001). The Research Center, Education and Medical Services for Diabetes in Puerto Rico (also known as the "Centro de Diabetes para Puerto Rico" [CDPR]) is a public corporation in the island created by the government to reduce diabetes prevalence, mortality and morbidity. The CDPR offers Diabetes Self Management Educational Training Program Schools for patients (DSMETPS) island wide. The research design was an ex-post facto. As part of the process, patients are administered an extensive sociodemographic and health information questionnaire, which also includes the CES-D (a symptomatology depressive scale). This study pretends to describe the diabetic patient profiles (n=27) using information from the DSMETPS of the CDPR and explore the association with the CES-D. Variables such as patients' needs, knowledge and understanding of the condition (i.e., pathology management, type and medications utilized and exercise and nutritional patterns), patient attitudes to diabetes and their relations with the CES-D were explored. Results show a negative association, controlling for age and gender, between patients diabetic education/knowledge and CES-D score. Diabetes educators in Puerto Rico need to identify depressive symptomatology in order to prevent mental health complications in their patients since this may affect their future treatment and prognosis. An interdisciplinary team is recommended to improve the effectivity of the intervention.

The 10-item Centre for Epidemiological Studies Depression Scale (CES-D-10) is a depression screening tool that has been used in the South African National Income Dynamics Study (NIDS), a national household panel study. This screening tool has not yet been validated in South Africa. This study aimed to establish the reliability and validity of the CES-D-10 in Zulu, Xhosa and Afrikaans. The CES-D-10's psychometric properties were also compared to the Patient Health Questionnaire (PHQ-9), a depression screening tool already validated in South Africa. Stratified random samples of Xhosa, Afrikaans and Zulu-speaking participants aged 15 years or older (N = 944) were recruited from Cape Town Metro and Ethekwini districts. Face-to-face interviews included socio-demographic questions, the CES-D-10, Patient Health Questionnaire (PHQ-9), and WHO Disability Assessment Schedule 2.0 (WHODAS). Major depression was determined using the Mini International Neuropsychiatric Interview. All instruments were translated and back-translated to English. Construct validity was examined using exploratory factor analysis with varimax rotation. Receiver Operating Characteristics (ROC) curves were used to investigate the CES-D-10 and PHQ-9's criterion validity, and compared using the DeLong method. Overall, 6.6, 18.0 and 6.9% of the Zulu, Afrikaans and Xhosa samples were diagnosed with depression, respectively. The CES-D-10 had acceptable internal consistency across samples (α = 0.69-0.89), and adequate concurrent validity, when compared to the PHQ-9 and WHODAS. The CES-D-10 area under the Receiver Operator Characteristic curve was good to excellent: 0.81 (95% CI 0.71-0.90) for Zulu, 0.93 (95% CI 0.90-0.96) for Afrikaans, and 0.94 (95% CI 0.89-0.99) for Xhosa. A cut-off of 12, 11 and 13 for Zulu, Afrikaans and Xhosa, respectively, generated the most balanced sensitivity, specificity and positive predictive value (Zulu: 71.4, 72.6% and 16.1%; Afrikaans: 84.6%, 84.0%, 53.7%; Xhosa: 81

Después de una búsqueda exhaustiva en la zona de estudio ubicamos menos de 30 individuos adultos de cada especie. Para cada planta se midieron las variables asociadas al tamaño de la planta y se registró el número y la longitud de raíces maduras e inmaduras. Se pesaron fragmentos de raíces para estimar la biomasa. El crecimiento de raíces de cada planta fue monitoreado mensualmente durante siete meses.

Efficient Overproduction of Membrane Proteins in Lactococcus lactis Requires the Cell Envelope Stress Sensor/Regulator Couple CesSR

Pinto, Joao P. C.; Kuipers, Oscar P.; Marreddy, Ravi K. R.; Poolman, Bert; Kok, Jan

2011-01-01

Background Membrane proteins comprise an important class of molecules whose study is largely frustrated by several intrinsic constraints, such as their hydrophobicity and added requirements for correct folding. Additionally, the complexity of the cellular mechanisms that are required to insert membrane proteins functionally in the membrane and to monitor their folding state makes it difficult to foresee the yields at which one can obtain them or to predict which would be the optimal production host for a given protein. Methods and Findings We describe a rational design approach to improve the lactic acid bacterium Lactococcus lactis as a producer of membrane proteins. Our transcriptome data shows that the two-component system CesSR, which senses cell envelope stresses of different origins, is one of the major players when L. lactis is forced to overproduce the endogenous membrane protein BcaP, a branched-chain amino acid permease. Growth of the BcaP-producing L. lactis strain and its capability to produce membrane proteins are severely hampered when the CesSR system itself or particular members of the CesSR regulon are knocked out, notably the genes ftsH, oxaA2, llmg_2163 and rmaB. Overexpressing cesSR reduced the growth defect, thus directly improving the production yield of BcaP. Applying this rationale to eukaryotic proteins, some of which are notoriously more difficult to produce, such as the medically-important presenilin complex, we were able to significantly diminish the growth defect seen in the wild-type strain and improve the production yield of the presenilin variant PS1Δ9-H6 more than 4-fold. Conclusions The results shed light into a key, and perhaps central, membrane protein quality control mechanism in L. lactis. Modulating the expression of CesSR benefited the production yields of membrane proteins from different origins. These findings reinforce L. lactis as a legitimate alternative host for the production of membrane proteins. PMID:21818275

Although CNVs contribute substantially to genomic variation, few genetic and imaging studies report association of CNVs with alcohol dependence (AD). Our purpose is to find evidence of this association across ethnic populations and genders. This work is the first AD-CNV study across ethnic groups and the first to include the African American (AA) population. This study considers 2 CNV data sets, one for discovery (2,345 samples) and the other for validation (239 samples), both including subjects with AD and healthy controls of European and African ancestry. Our analysis assesses the association between AD and CNV losses across ethnic groups and gender by examining the effect of overall losses across the whole genome, collective losses within individual cytogenetic bands, and specific losses in CNV regions. Results from the discovery data set showed an association between CNV losses within 16q12.2 and AD diagnosis (p = 4.53 × 10(-3) ). An overlapping CNV region from the validation data set exhibited the same direction of effect with respect to AD (p = 0.051). This CNV region affects the genes CES1p1 and CES1, which are members of the carboxylesterase (CES) family. The enzyme encoded by CES1 is a major liver enzyme that typically catalyzes the decomposition of ester into alcohol and carboxylic acid and is involved in drug or xenobiotics, fatty acid, and cholesterol metabolisms. In addition, the most significantly associated CNV region was located at 9p21.2 (p = 1.9 × 10(-3) ) in our discovery data set. Although not observed in the validation data set, probably due to small sample size, this result might hold potential connection to AD given its connection with neuronal death. In contrast, we did not find any association between AD and the overall total losses or the collective losses within individual cytogenetic bands. Overall, our study provides

Systems Analysis of Interaction between Russia and the European Union in the Post-Soviet Space

Full Text Available This article analyzes post-Soviet relations between Russia and the European Union using the theoretical framework of neoclassical realism. It finds that the post-Soviet level of competition between Russia and the EU is higher than required by the international system. The reason is rooted in the influence of a number of internal factors (or intervening variables. Consequently, elites in both Russia and the EU are not able to adequately understand the signals sent by the international system. There is a wide variety of intervening variables; for example, there are factors caused by the political elites’ perceptions of each other’s intentions and of the international situation, factors related to inadequate information, factors related to the complex institutional structure of the EU and factors related to domestic political issues. In addition, the current international environment, characterized by a high degree of uncertainty, increases the effects of these intervening variables. These effects result in inaccurate and incorrect processing of the signals of the international system by Russian and European elites. As a result, a subsystem of international relations has arisen in the post-Soviet space, featuring a highly competitive environment. However, there are only two major actors in the region: Russia and the EU. Small countries are too weak, so must choose to align themselves with either Russia or the Euone or the other. This causes a rivalry between Russia and the EU for influence on small and medium-sized countries in the post-Soviet space.

A partnership established between the European Space Agency (ESA) and the U.S. Geological Survey (USGS) allows for USGS storage and redistribution of images acquired by the MultiSpectral Instrument (MSI) on the European Union's Sentinel-2 satellite mission. The MSI data are acquired from a pair of satellites, Sentinel-2A and Sentinel-2B, which are part of a larger set of ESA missions focusing on different aspects of Earth observation. The primary purpose of the Sentinel-2 series is to collect multispectral imagery over the Earth’s land surfaces, large islands, and inland and coastal waters. Sentinel-2A was launched in 2015 and Sentinel-2B launched in 2017.The collaborative effort between ESA and USGS provides for public access and redistribution of global acquisitions of Sentinel-2 data at no cost, which allows users to download the MSI imagery from USGS access systems such as Earth- Explorer, in addition to the ESA Sentinels Scientific Data Hub. The MSI sensor acquires 13 spectral bands that are highly complementary to data acquired by the USGS Landsat 8 Operational Land Imager (OLI) and Landsat 7 Enhanced Thematic Mapper Plus (ETM+). The product options from USGS include a Full-Resolution Browse (FRB) image product generated by USGS, along with a 100-kilometer (km) by 100-km tile-based Level-1C top-of-atmosphere (TOA) reflectance product that is very similar (but not identical) to the currently (2017) distributed ESA Level 1C product.

Full Text Available Abstract Background Depression is a common co-morbid health problem in patients with diabetes that is underrecognised. Current international guidelines recommend screening for depression in patients with diabetes. Yet, few depression screening instruments have been validated for use in this particular group of patients. Aim of the present study was to investigate the psychometric properties of the Turkish version of the Centre for Epidemiologic Studies Depression Scale (CES-D in patients with type 2 diabetes. Methods A sample of 151 Turkish outpatients with type 2 diabetes completed the CES-D, the World Health Organization-Five Well-Being Index (WHO-5, and the Problem Areas in Diabetes scale (PAID. Explanatory factor analyses, various correlations and Cronbach's alpha were investigated to test the validity and reliability of the CES-D in Turkish diabetes outpatients. Results The original four-factor structure proposed by Radloff was not confirmed. Explanatory factor analyses revealed a two-factor structure representing two subscales: (1 depressed mood combined with somatic symptoms of depression and (2 positive affect. However, one item showed insufficient factor loadings. Cronbach's alpha of the total score was high (0.88, as were split-half coefficients (0.77-0.90. The correlation of the CES-D with the WHO-5 was the strongest (r = -0.70, and supported concurrent validity. Conclusion The CES-D appears to be a valid measure for the assessment of depression in Turkish diabetes patients. Future studies should investigate its sensitivity and specificity as well as test-retest reliability.

European astronomers' successes with the Hubble Space Telescope*

can bend the light from more distant objects, so magnifying and intensifying their images. In one spectacular case, cluster Abell 2218 creates in Hubble's WFPC2 camera more than a hundred images of galaxies lying beyond it. Without the magnifying effect of the cluster, many of these remote objects would be too faint to study in detail. Compared with man-made optics, the gravitational lenses are complex. They produce multiple images (as many as seven or more views of the same object) and they also smear the images into arcs. Team-member Jean-Paul Kneib, who is now at Toulouse, uses the distortions as a guide to distance. The more distorted the image, the farther off a galaxy is. The galaxies imaged by Abell 2218 are 5 to 8 billion light-years away, and Kneib's estimates have been confirmed by Tim Ebbels of Cambridge using the William Herschel Telescope located on the Spanish island of La Palma. Seen as they were early in the history of the Universe, the objects seem surprisingly similar to nearer and more mature galaxies. The cosmic scale Gustav Tammann of Basel and his collaborators use the Hubble Space Telescope to measure the Hubble Constant. Both are named after Edwin Hubble who discovered, almost 70 years ago, that the galaxies are spreading apart. The Hubble Constant is the rate of expansion -- and the most important number in cosmology, because it fixes the size and the maximum age of the observable Universe. Since the launch of the space telescope in 1990, two independent teams have tried to fix the constant but their answers disagree. A high expansion rate, which makes the Universe relatively young, is preferred by Wendy Freedman's team consisting largely of American astronomers. A lower value for Hubble's Constant, implying an older Universe, comes from a mainly European team led by the American astronomer Allan Sandage. Tammann belongs to the latter, "old Universe" camp and he is philosophical about the delay in reaching a consensus. "I've been waiting

Full Text Available Ongoing discussions between Russia and the EU on the formation of a Common European Economic Space bring back to mind Alexander Gerschenkron's classic essay on economic backwardness in historical perspective. This paper argues that the institutions that once produced a specific kind of catch-up economics in Czarist Russia still remain largely the same. Unless negotiations between Moscow and Brussels take into consideration such fundamental institutional incompatibility, attempts at harmonization, expressed by Brussels as an attempt tp spread Western values, will be doomed to fail. A cynical conlusion views potential convergence as adaptation by Brussels to traditional Russian institutional patterns of rule evasion, rather than a Westernization of Russia

MÉTODOS: foi realizado estudo longitudinal, do tipo caso-controle com 3626 gestantes, no qual se verificou quais os fatores anteparto foram considerados de risco para cesárea, no período de 1 de setembro de 1999 a 31 de agosto de 2000. Posteriormente, criou-se modelo preditivo ideal, o qual permitiu quantificar o risco de cesárea para cada paciente na presença de um ou mais fatores de risco. A seguir, aplicou-se o modelo à amostra do estudo a fim de verificar o grau de concordância entre o risco previsto de cesárea e a realização do ato cirúrgico, ou seja, a eficácia na indicação de cesariana. RESULTADOS: aplicando-se o modelo preditivo na amostra, verificou-se que na ausência dos fatores de riscos anteparto, o risco basal de cesárea foi de 15,2%. O grau de concordância entre o previsto pelo modelo logístico e a ocorrência de cesárea foi de 86,6%. CONCLUSÕES: o modelo logístico permitiu identificar o risco basal de cesárea e quantificar a probabilidade de cesárea a partir da introdução do fator de risco. O modelo pode ser considerado útil e eficaz, uma vez que houve concordância entre o acerto e o previsto em 86,6% para cesariana, e 53,6% das pacientes submetidas ao parto normal, de fato, não tinham fator de risco para cesárea.PURPOSE: to create a predictive model for cesarean section at the "Professor Monteiro de Morais Maternity" after evaluation of antepartum risk factors of the pregnant women who delivered from September 1, 1999 to August 31, 2000, and then, to verify the efficacy of indication for cesarean section.

Spain: Success story in space

Science.gov (United States)

Longdon, Norman

From the early 1960's, European governments were aware that they had to take part in the exploration, and potential exploitation, of space, or be left behind in a field of high-technology that had far-reaching possibilities. It was also realized that financial and manpower constraints would limit the extent to which individual nations could carry out their own national programs. They, therefor, joined forces in two organizations: the European Space Research Organization (ESRO) and the European Launcher Development Organization (ELDO). By 1975, when the potential of space development had been more fully appreciated, the two organizations were merged into the Europeans Space Agency (ESA) of which Spain was a founding member. ESA looks after the interest of 13 member states, one associated member state (Finland), and one cooperating state (Canada) in the peaceful uses of space. Its programs center around a mandatory core of technological research and space science to which member states contribute on the basis of their Gross National Product. Spain in 1992 contributes 6.46% to this mandatory program budget. The member states then have the chance to join optional programs that include telecommunications, observation of the earth and its environment, space transportation systems, microgravity research, and participation in the European contribution to the International Space Station Freedom. Each government decides whether it is in its interest to join a particular optional program, and the percentage that it wishes to contribute to the budget. Although in the early days of ESA, Spain participated in only a few optional programs, today Spain makes a significant contribution to nearly all of ESA's optional programs. This document presents Spain's contributions to particular ESA Programs and discusses Spain's future involvement in ESA.

The ExoMars 2016 mission, consisting of the Trace Gas Orbiter and the Schiaparelli lander, was launched on March 14 2016 from Baikonur, Kazakhstan and reached its destination in October 2016. The Schiaparelli lander was subject to strict requirements for microbial cleanliness according to the obligatory planetary protection policy. To reach the required cleanliness, the ExoMars 2016 flight hardware was assembled in a newly built, biocontrolled cleanroom complex at Thales Alenia Space in Turin, Italy. In this study, we performed microbiological surveys of the cleanroom facilities and the spacecraft hardware before and during the assembly, integration and testing (AIT) activities. Besides the European Space Agency (ESA) standard bioburden assay, that served as a proxy for the microbiological contamination in general, we performed various alternative cultivation assays and utilised molecular techniques, including quantitative PCR and next generation sequencing, to assess the absolute and relative abundance and broadest diversity of microorganisms and their signatures in the cleanroom and on the spacecraft hardware. Our results show that the bioburden, detected microbial contamination and microbial diversity decreased continuously after the cleanroom was decontaminated with more effective cleaning agents and during the ongoing AIT. The studied cleanrooms and change room were occupied by very distinct microbial communities: Overall, the change room harboured a higher number and diversity of microorganisms, including Propionibacterium, which was found to be significantly increased in the change room. In particular, the so called alternative cultivation assays proved important in detecting a broader cultivable diversity than covered by the standard bioburden assay and thus completed the picture on the cleanroom microbiota. During the whole project, the bioburden stayed at acceptable level and did not raise any concern for the ExoMars 2016 mission. The cleanroom complex at

Full Text Available OBJETIVO: Describir el comportamiento de las cesáreas en México en los últimos 10 años y medir su relación con distintas variables. MATERIAL Y MÉTODOS: Estudio ecológico en el que se utilizó la base de datos de nacimientos atendidos en instituciones de salud públicas y privadas que concentra la Secretaría de Salud de México. La variable dependiente fue el tipo de atención del parto. Las variables independientes fueron el producto interno bruto per cápita, el índice de desarrollo humano, el porcentaje de analfabetismo de las mujeres, el nivel de marginación y el porcentaje de médicos especialistas, entre otras. La relación entre las variables en estudio se midió con las pruebas de correlación de Pearson y de Spearman. Con los datos de 1999 se realizó un análisis de regresión lineal múltiple para identificar las principales variables asociadas con el porcentaje de cesáreas por entidad federativa. RESULTADOS: El porcentaje de nacimientos por cesárea en el ámbito nacional se incrementó en los últimos 10 años a un ritmo ligeramente superior a 1% anual. El ritmo de crecimiento fue considerablemente mayor en la seguridad social y el sector privado. El porcentaje de cesáreas a escala nacional en 1999 fue ligeramente superior a 35%. Los valores más altos correspondieron al sector privado con 53%. Las instituciones de seguridad social presentaron un porcentaje de cesáreas de 38.2%. Las variables con valores de asociación más intensa con el porcentaje de cesáreas fueron el porcentaje de médicos que son especialistas en el estado y el producto interno bruto per cápita. DISCUSIÓN: Los resultados presentados respaldan las opiniones que defienden la implantación de políticas correctivas específicas, con el fin de impulsar un descenso en la frecuencia de cesáreas. En otros contextos se han producido descensos importantes con requisitos como la solicitud de una segunda opinión antes de realizar una cesárea, la definici

We present a pragmatic approach to image reconstruction for data from the micro crystal elements system (MiCES) fully 3D mouse imaging positron emission tomography (PET) scanner under construction at the University of Washington. Our approach is modelled on fully 3D image reconstruction used in clinical PET scanners, which is based on Fourier rebinning (FORE) followed by 2D iterative image reconstruction using ordered-subsets expectation-maximization (OSEM). The use of iterative methods allows modelling of physical effects (e.g., statistical noise, detector blurring, attenuation, etc), while FORE accelerates the reconstruction process by reducing the fully 3D data to a stacked set of independent 2D sinograms. Previous investigations have indicated that non-stationary detector point-spread response effects, which are typically ignored for clinical imaging, significantly impact image quality for the MiCES scanner geometry. To model the effect of non-stationary detector blurring (DB) in the FORE+OSEM(DB) algorithm, we have added a factorized system matrix to the ASPIRE reconstruction library. Initial results indicate that the proposed approach produces an improvement in resolution without an undue increase in noise and without a significant increase in the computational burden. The impact on task performance, however, remains to be evaluated

Full Text Available Objective: Compulsive or binge eating is a kind of disturbed eating behavior, which is mostly observed among dieting women, and is integrated with appetite disorder, and uncontrolled eating of plenty of junk food. The Compulsive Eating Scale (CES created first by Kagan & Squires in 1984, is an eight-item self-reporting instrument that is made to measure the severity of binge eating disorder. The aim of this study was to provide the reliability and validity of the Persian version of Compulsive Eating Scale (CES among overweight and obese women in Iran. Method: One hundred and twenty six (N = 126 overweight and obese women consented to participate in this study. We estimated the anthropometric indices, including body weight, height, waist and hip circumferences, a total body fat percentage, and visceral fat level with body analyzer all in standard situations. Then, the participants completed the CES. Next, to assess concurrent validity, Beck Depression Inventory, Spielberger anxiety scale, appetite visual analogue rating scale, Food Craving questionnaire, Three-Factor Eating Questionnaire-R18, and Restraint eating visual analogue rating scale were performed simultaneously. To assess test-retest reliability, CES was repeated for all the participants two weeks later. Moreover, we reported the internal consistency and factor analysis of this questionnaire. Furthermore, we estimated the concurrent correlation of CES with logically relevant questionnaires and body composition and anthropometric indices.Results: Based on the reliability analysis and factor analysis of the principal component by Varimax rotation, we extracted two factors: eating because of negative feelings, and overeating. Internal consistency (Cronbach's alpha of the CES was 0.85 (Cronbach alpha of the factors was 0.85, and 0.74, respectively. The test-retest correlation of the CES was 0.89. Also, the split-half reliability of the questionnaire was established with the correlation

Full Text Available The EU judicial cooperation in civil matters system was developed following the needs of member states to achieve a common goal, which is to create a space of mutual recognition of judgements and distribute the juridical effects of the order created under one jurisdiction thru out the entire European space. One of the main pillars of this system is the creation of European Enforcement Orders, judgements or other titles enforceable in a member state without prior recognition of declaration of enforceability. This system has been developed other the years, starting with the European Enforcement Order for uncontested claims, continuing with the European Order for Payment procedure and European Small Claims procedure, and reaching its peak in Regulation (EU 1215/2012. By virtue of this Regulation, entered into force in January 2015, a judgment given in a Member State which is enforceable in that Member State shall be enforceable in the other Member States without any declaration of enforceability being required (art. 39. The article analyses the evolution of EU regulation regarding the enforceability of foreign judgements and the system created under Regulation (EU 1215/2012, given its importance for the judicial cooperation in civil matters and its impact on the legislation of member stated. Also, a brief analysis of the provisions of the new Romanian civil procedure Code is made, given its amendments by Law no. 138/2014.

It has been suggested that certain residents, such as those with a low socioeconomic status, the elderly, and women, may benefit more from the presence of neighbourhood green space than others. We tested this hypothesis for age, gender, educational level, and employment status in four European cities. Data were collected in Barcelona (Spain; n = 1002), Kaunas (Lithuania; n = 989), Doetinchem (The Netherlands; n = 847), and Stoke-on-Trent (UK; n = 933) as part of the EU-funded PHENOTYPE project. Surveys were used to measure mental and general health, individual characteristics, and perceived neighbourhood green space. Additionally, we used audit data about neighbourhood green space. In Barcelona, there were positive associations between neighbourhood green space and general health among low-educated residents. In the other cities and for the other population groups, there was little evidence that the association between health and neighbourhood green space differed between population groups. Overall, our study does not support the assumption that the elderly, women, and residents who are not employed full-time benefit more from neighbourhood green space than others. Only in the highly urbanised city of Barcelona did the low-educated group benefit from neighbourhood green spaces. Perhaps neighbourhood green spaces are more important for the health of low-educated residents in particularly highly urbanised areas. PMID:28594390

Full Text Available Gravidez ectópica na cicatriz de cesárea é a forma mais rara de gravidez ectópica e provavelmente uma das mais perigosas em função dos riscos de ruptura e hemorragia volumosa. Essa situação deve ser diferenciada da gravidez cervical e de abortamento em curso, para que o tratamento apropriado seja imediatamente oferecido. Desde o advento da ultra-sonografia transvaginal, a gravidez ectópica na cicatriz de cesárea pode ser diagnosticada precocemente na gestação e, para isso o ultra-sonografista deve estar familiarizado com e atento aos critérios diagnósticos, especialmente em mulheres com cicatriz de cesárea prévia. Descrevemos aqui um caso de gravidez ectópica em cicatriz de cesárea, cujo diagnóstico foi tardio, havendo apresentação de involução espontânea.Ectopic pregnancy in a cesarean scar is the rarest form of ectopic pregnancy and probably the most dangerous one because of the risk of uterine rupture and massive hemorrhage. This condition must be distinguished from cervical pregnancy and spontaneous abortion in progress, so that the appropriate treatment can be immediately offered. Since the advent of endovaginal ultrasonography, ectopic pregnancy in a cesarean scar can be diagnosed early in pregnancy if the sonographer is familiarized with the diagnostic criteria of this situation, especially in women with previous cesarean scar. Here we describe a case of ectopic pregnancy in a cesarean scar in which the diagnosis was considerably late, with presentation of spontaneous regression.

Full Text Available We believe that globalization and its socio-economic implications of the world and world economic crisis is one of the most debated issues from several years. The publication "The Economist’’ named globalization as the most used word of the century. The most relevant dimension of globalization is the economy with the more dynamic factors: technological development, the hegemony of liberal conceptions (closely linked to the triumph of the ideology of market economy and explosive development of countries or regions. Economic globalization has manifested a series of visible effects such as: the emergence of new markets and foreign trade (interconnected at global level, the appearance of: transnational companies, multilateral agreements on trade, broadening the scope of WTO, transformation of multinational companies in transnational companies and the emergence of global economic markets. Regionally, we noticed that the trendof concentration of economic activity is more pronounced and advanced in the European continent. Expanding globalization in Europe was achieved because of the fall of communism, and the neoliberal reformation which took place in Western European countries. Events like the fall of the Berlin Wall, followed by the fall of communism eradicated many political, economic, religious or cultural barriers. There were born new relations between state and market, public and private. European Union is, in our view, a regional office ofglobalization, representing the best performing integrative system in the world (by creating free trade area, customs union, common market, the Economic and Monetary Union. In terms of the European Commission,European model is a third way towards globalization, a middle path between protectionism and uncontrolled economy. To understand why the EU is an advanced approximation of globalization, perhaps a regional model of globalization, we must first understand the link between globalization and regional

Full Text Available Aims: Depression is one of the most common mental disorders in children, and in adolescents, as in adults. Once its occurrence during childhood and adolescence leads to serious consequences in adulthood, its early detection is an important goal. Self-report instruments have a key role on accessing thoughts, feelings and behaviors in an easily, reliably and validly way. The aim of the current study is to assess psychometric properties (reliability and validity of the Portuguese translation of the Center for Epidemiological Studies-Depression Scale for Children (CES-DC. Methods: A school-based sample of 417 adolescents aged 12–18 years (M = 15,20, SD = 1,72 was involved in this study. Translation and Back Translation was made. To study convergent and divergent validity there were used the Portuguese versions of the Depression Anxiety Stress Scales (DASS 21, of the Children's Depression Inventory (CDI, and of the Students' Life Satisfaction Scale (SLSS which measure, respectively, negative emotional states (depression, anxiety and stress, depressive symptoms and global life satisfaction. Results: Factor analysis revealed three factors (mood, interpersonal relationships and happiness that explain 54% of the variance. The results show that the scale has an excellent internal consistency (α = 0,90, good temporal stability (r = 0,72 as an adequate convergent and divergent validity. Results showed that depressive symptoms varied in function of age and gender. Conclusions: The results of the present study provide initial adequate validity and reliability of the CES-DC. Nevertheless some limitations to this study, the results suggest that CES-DC can be a useful questionnaire in the assessment of depressive symptoms in Portuguese adolescents.

Full Text Available Identification of biomarkers to recognize individuals with Barrett's esophagus (BE predisposed to develop malignancy is currently a pressing issue. We utilized gene expression profiling to compare molecular signatures of normal esophagus and stomach, BE, and adenocarcinoma (AC to identify such potential biomarkers. Over 22,000 genes were analyzed by oligonucleotide microarrays on 38 unique RNA. Unsupervised and supervised clusterings were performed on a subset of 2849 genes that varied most significantly across the specimens. Unsupervised clustering identified two discernable molecular BE profiles, one of which was similar to normal gastric tissue (“BE1”, and another that was shared by several of the AC specimens (“BE2”. The BE1 profile included expression of several genes that have been described as tumor-suppressor genes, most notably trefoil factor 1 (TFF-1. The BE2 profile included expression of genes previously found overexpressed in cancers, such as carboxylesterase-2 (CES-2. IHC demonstrated the loss of TFF-1 late in the progression of BE to AC. It also revealed CES-2 as being upregulated in AC documented to have arisen in the presence of BE. These potential biomarkers, as well as the relative expression of genes from BE1 versus those from BE2, may be validated in the future to aid in risk stratification and guide treatment protocols in patients with BE and associated AC.

Listeria monocytogenes is a food-borne pathogen that can cause a variety of illnesses ranging from gastroenteritis to life-threatening septicemia. The beta-lactam antibiotic ampicillin remains the drug of choice for the treatment of listeriosis. We have previously identified a response regulator...... of L. monocytogenes to tolerate ethanol and cell wall-acting antibiotics of the beta-lactam family. Furthermore, CesRK controls the expression of a putative extracellular peptide encoded by the orf2420 gene, located immediately downstream from cesRK. Inactivation of orf2420 revealed that it contributes...... to ethanol tolerance and pathogenesis in mice. Interestingly, we found that transcription of orf2420 was strongly induced by subinhibitory concentrations of various cell wall-acting antibiotics, ethanol, and lysozyme. The induction of orf2420 expression was abolished in the absence of CesRK. Our data suggest...

Full Text Available It has been suggested that certain residents, such as those with a low socioeconomic status, the elderly, and women, may benefit more from the presence of neighbourhood green space than others. We tested this hypothesis for age, gender, educational level, and employment status in four European cities. Data were collected in Barcelona (Spain; n = 1002, Kaunas (Lithuania; n = 989, Doetinchem (The Netherlands; n = 847, and Stoke-on-Trent (UK; n = 933 as part of the EU-funded PHENOTYPE project. Surveys were used to measure mental and general health, individual characteristics, and perceived neighbourhood green space. Additionally, we used audit data about neighbourhood green space. In Barcelona, there were positive associations between neighbourhood green space and general health among low-educated residents. In the other cities and for the other population groups, there was little evidence that the association between health and neighbourhood green space differed between population groups. Overall, our study does not support the assumption that the elderly, women, and residents who are not employed full-time benefit more from neighbourhood green space than others. Only in the highly urbanised city of Barcelona did the low-educated group benefit from neighbourhood green spaces. Perhaps neighbourhood green spaces are more important for the health of low-educated residents in particularly highly urbanised areas.

Communicative competences in Experimental Sciences degrees within the framework of the new European Space for Higher Education

2009-10-01

Full Text Available The scenario for developing communicative competences in the Experimental Sciences degrees and within the new European Space for Higher Education is highly complex. This is confirmed by research reported in the White Papers on the new degrees in this subject area. Therefore, to smoothly integrate communicative and linguistic competences into future syllabi, I should first make a careful analysis of the main factors at work in the new situation. This paper seeks to provide a preliminary approach to the problem. First, I describe the academic and professional tasks that constitute the objectives of future European science degrees. This is followed by an analysis of the communicative and linguistic parameters considered essential for satisfactory attainment of these objectives. Finally, the specific skills that students must master in order to meet the demands imposed by the new framework are outlined. The results of this analysis will enable us to see how much the new situation differs from traditional university teaching. Under this new model, the development of communicative and linguistic competences will no longer be a mere adjunct to a science curriculum, but instead will become of prime importance to the academic and professional training of future scientists.

Double Taxation Conventions in Central and Eastern European Countries

Dumiter Florin

2016-12-01

Full Text Available In this article we provide a qualitative overview regarding the panacea of double taxation conventions in Central and Eastern European Countries. Double taxation paradigm highlights some serious problems arising from multiple taxation of the same income or capital. In the European Union these problems suggest that there is a strong need of a “best practice” construction of an optimal fiscal space in order to eliminate or reduce this problem. Central and Eastern European Countries have some special features: on one hand these countries have been influenced by the communist and postcommunism era, and on the other hand there are specific particularities for each country which must be economically and judicially understood and explained. This article highlights the structure, construction and appliance of the double taxation conventions in the Central and Eastern European Countries. The conclusions of this article enact the solutions of the potential problems of double taxation, especially in these former communist countries, with respect to the strengthening of the new fiscal space in the European Union.

Space and Ground-Based Infrastructures

Science.gov (United States)

Weems, Jon; Zell, Martin

This chapter deals first with the main characteristics of the space environment, outside and inside a spacecraft. Then the space and space-related (ground-based) infrastructures are described. The most important infrastructure is the International Space Station, which holds many European facilities (for instance the European Columbus Laboratory). Some of them, such as the Columbus External Payload Facility, are located outside the ISS to benefit from external space conditions. There is only one other example of orbital platforms, the Russian Foton/Bion Recoverable Orbital Capsule. In contrast, non-orbital weightless research platforms, although limited in experimental time, are more numerous: sounding rockets, parabolic flight aircraft, drop towers and high-altitude balloons. In addition to these facilities, there are a number of ground-based facilities and space simulators, for both life sciences (for instance: bed rest, clinostats) and physical sciences (for instance: magnetic compensation of gravity). Hypergravity can also be provided by human and non-human centrifuges.

Space Use and Movement Patterns in a Semi-Free-Ranging Herd of European Bison (Bison bonasus.

Directory of Open Access Journals (Sweden)

Amandine Ramos

Full Text Available The successful reintroduction and restocking of the European Bison demands a reliable knowledge of the biology of this species. Yet little is known to date about the European bison, and empirical data remains insufficient to set up a reliable plan ensuring the reintroduction, maintenance and survival of populations in habitats that have been largely modified by human activity. Studies of the ecology, social behaviour and management of bison are therefore crucial to the conservation of this species and its cohabitation with humans. To meet these challenges, we focused on movement patterns and space use in a semi-free-ranging herd of European bison living in the Réserve Biologique des Monts-d'Azur (France. Bison spend over 80% of their time foraging and resting; foraging mainly occurs around the artificial feeding sites (i.e., hay racks or in meadows. The time of day and the presence of snow have no influence on the time budget allocated to each activity. Animals, however, spend more time at the food racks in winter. Bison also spend most of their time in small groups of individuals, confirming the occurrence of both fission-fusion dynamics and sexual segregation in this species. Bison seem to follow a Lévy walk pattern of movement, which is probably related to the geographical distribution and size of food patches in the reserve. The conclusions of this study provide a better understanding of the sociality, life habits and habitat use of bison, and also describe how the provision of hay affects all these behaviours. These results could be useful in the development of tools to select the most suitable habitats for the reintroduction, management and conservation of bison populations.

2011-01-01

With the launch of the European Space Agency's Aeolus Mission in 2013, direct spaceborne measurements of vertical wind profiles are imminent via Doppler wind lidar technology. Part of the preparedness for such missions is the development of the proper data assimilation methodology for handling such observations. Since no heritage measurements exist in space, the Joint Observing System Simulation Experiment (Joint OSSE) framework has been utilized to generate a realistic proxy dataset as a precursor to flight. These data are being used for the development of the Gridpoint Statistical Interpolation (GSI) data assimilation system utilized at a number of centers through the United States including the Global Modeling and Assimilation Office (GMAO) at NASA/Goddard Space Flight Center and at the National Centers for Environmental Prediction (NOAA/NWS/NCEP) as an activity through the Joint Center for Satellite Data Assimilation. An update of this ongoing effort will be presented, including the methodology of proxy data generation, the limitations of the proxy data, the handling of line-of-sight wind measurements within the GSI, and the impact on both analyses and forecasts with the addition of the new data type.

All the requests for authorisation to bear health claims under Articles 13(5) and 14 in the context of appetite ratings and weight management have received a negative opinion by the European Food Safety Authority (EFSA), mainly because of the insufficient substantiation of the claimed effects (CEs). This manuscript results from an investigation aimed to collect, collate and critically analyse the information related to outcome variables (OVs) and methods of measurement (MMs) in the context of appetite ratings and weight management compliant with Regulation 1924/2006. Based on the literature review, the appropriateness of OVs and MMs was evaluated for specific CEs. This work might help EFSA in the development of updated guidance addressed to stakeholders interested in bearing health claims in the area of weight management. Moreover, it could drive the applicants during the design of randomised controlled trials aimed to substantiate such claims.

, also by standards. These assertions, to which we can add also others, are leading to a new model of public administration, whose area overlaps with the space of European Union, incorporating the effects of globalization under its European expression, Europeanization. Consequently, the proposed model, emphasizing the process of European Union construction will comprise transparency, accountability and participation of the interested parties to public decision. The new public administration aims to use efficiently the resources in order to create favourable conditions for its citizens to become more competitive on the world market and to reduce the gap between the poorest and the richest inhabitants of the world. The current paper aims to conceptualize and to describe a model of public administration. The architecture of this model will be that of a complex system, with a mixed architecture, emphasizing connections with different intensities among its various levels: European, regional, national etc. The feedback mechanisms will be different and specific for each level and they will be ensured by different institutions on compatible normative grounds(1.

Objectives Increasingly, medical research involves patients who complete outcomes in different languages. This occurs in countries with more than one common language, such as Canada (French/English) or the United States (Spanish/English), as well as in international multi-centre collaborations, which are utilized frequently in rare diseases such as systemic sclerosis (SSc). In order to pool or compare outcomes, instruments should be measurement equivalent (invariant) across cultural or linguistic groups. This study provides an example of how to assess cross-language measurement equivalence by comparing the Center for Epidemiologic Studies Depression (CES-D) scale between English-speaking Canadian and Dutch SSc patients. Methods The CES-D was completed by 922 English-speaking Canadian and 213 Dutch SSc patients. Confirmatory factor analysis (CFA) was used to assess the factor structure in both samples. The Multiple-Indicator Multiple-Cause (MIMIC) model was utilized to assess the amount of differential item functioning (DIF). Results A two-factor model (positive and negative affect) showed excellent fit in both samples. Statistically significant, but small-magnitude, DIF was found for 3 of 20 items on the CES-D. The English-speaking Canadian sample endorsed more feeling-related symptoms, whereas the Dutch sample endorsed more somatic/retarded activity symptoms. The overall estimate in depression scores between English and Dutch was not influenced substantively by DIF. Conclusions CES-D scores from English-speaking Canadian and Dutch SSc patients can be compared and pooled without concern that measurement differences may substantively influence results. The importance of assessing cross-language measurement equivalence in rheumatology studies prior to pooling outcomes obtained in different languages should be emphasized. PMID:23326538

Giannopapa, Christina; Adriaensen, Maarten; Antoni, Ntorina; Schrogl, Kai-Uwe

2018-06-01

In the past decade Europe has been facing rising security threats, ranging from climate change, migrations, nearby conflicts and crises, to terrorism. The demand to tackle these critical challenges is increasing in Member States. Space is already contributing, and could further contribute with already existing systems and future ones. The increasing need for security in Europe and for safety and security of Europe's space activities has led to a growing number of activities in ESA in various domains. It has also driven new and strengthened partnerships with security stakeholders in Europe. At the European level, ESA is collaborating closely with the main European institutions dealing with space security. In addition, as an organisation ESA has evolved to conduct security-related projects and programmes and to address the threats to its own activities, thereby securing the investments of the Member States. Over the past years the Agency has set up a comprehensive regulatory framework in order to be able to cope with security related requirements. Over the past years, ESA has increased its exchanges with its Member States. The paper presents main elements of the ESA's policy on space and security. It introduces the current European context for space and security, the European goals in this domain and the specific objectives to which the Agency intends to contribute. Space and security in the ESA context is set out under two components: a) security from space and b) security in space, including the security of ESA's own activities (corporate security and the security of ESA's space missions). Subsequently, ESA's activities are elaborated around these two pillars, composed of different activities conducted in the most appropriate frameworks and in coordination with the relevant stakeholders and shareholders.

Welfare Effects of Tax and Price Changes and the CES-UT Utility Function

DEFF Research Database (Denmark)

Munk, Knud Jørgen

Dixit's 1975 paper "Welfare Effects of Tax and Price Changes" constitutes a seminal contribution to the theory of tax reform within a second-best general equilibrium framework. The present paper clarifies ambiguities with respect to normalisation which has led to misinterpretation of some of Dixit......'s analytical results. It proves that a marginal tax reform starting from a proportional tax system will improve social welfare if it increases the supply of labour, whatever the rule of normalisation adopted. In models which impose additive separability between consumption and leisure in household preferences...... elasticities can be derived from the parameters of the CES-UT and how it may be used for applied tax reform analysis...

On Wednesday, February 16, 1994, seven NASA and ESA astronauts and their spouses will spend a day at the Headquarters of the European Southern Observatory. They are the members of the STS-61 crew that successfully repaired the Hubble Space Telescope during a Space Shuttle mission in December 1993. This will be the only stop in Germany during their current tour of various European countries. ESO houses the Space Telescope European Coordinating Facility (ST/ECF), a joint venture by the European Space Agency and ESO. This group of astronomers and computer specialists provide all services needed by European astronomers for observations with the Space Telescope. Currently, the European share is about 20 of the total time available at this telescope. During this visit, a Press Conference will be held on Wednesday, February 16, 11:45 - 12:30 at the ESO Headquarters Karl-Schwarzschild-Strasse 2 D-85748 Garching bei Munchen. Please note that participation in this Press Conference is by invitation only. Media representatives may obtain invitations from Mrs. E. Volk, ESO Information Service at this address (Tel.: +49-89-32006276; Fax.: +49-89-3202362), until Friday, February 11, 1994. After the Press Conference, between 12:30 - 14:00, a light refreshment will be served at the ESO Headquarters to all participants. >From 14:00 - 15:30, the astronauts will meet with students and teachers from the many scientific institutes in Garching in the course of an open presentation at the large lecture hall of the Physics Department of the Technical University. It is a 10 minute walk from ESO to the hall. Later the same day, the astronauts will be back at ESO for a private discussion of various space astronomy issues with their astronomer colleagues, many of whom are users of the Hubble Space Telescope, as well as ground-based telescopes at the ESO La Silla Observatory and elsewhere. The astronauts continue to Switzerland in the evening.

Full Text Available This paper focuses on the role of the teacher of English for Specific Purposes (ESP from the beginning of ESP research in the 80’s to date when educators are faced with the challenges of the European Space for Higher Education (ESHE and its implementation in educational systems across Europe. Firstly, the most outstanding aspects published in the relevant literature and dealing with the ESP teacher are explored and summarized. Secondly, the new roles to be played under the framework of ESHE are presented and discussed – it has been found that these new roles are not distinctively prescribed by ESHE but references to them are spread through the existing literature. Next, particular attention will be paid to «interdisciplinary collaboration». This notion is highlighted across ESHE instruments of implementation as a brand new practice in tertiary education but in the context of ESP it is a long-established goal with practical approaches adopted worldwide. As a way of conclusion, ESP teacher’s duties are listed bearing in mind the existing bibliography and the ESHE requirements.

Sensitivity of Earth Wheat Markets to Space Weather: Comparative Analysis based on data from Medieval European Markets

Science.gov (United States)

Pustil'Nik, Lev

We consider a problem of the possible influence of unfavorable states of the space weather on agriculture markets through the chain of connections: "space weather"-"earth weather"- "agriculture crops"-"price reaction". We show that new manifestations of "space weather"- "earth weather" relations discovered in the recent time allow revising a wide range of the expected solar-terrestrial connections. In the previous works we proposed possible mechanisms of wheat market reaction on the specific unfavorable states of space weather in the form of price bursts and price asymmetry. We point out that implementation of considered "price reaction scenarios" is possible only for the case of simultaneous realization of several necessary conditions: high sensitivity of local earth weather in the selected region to space weather; the state of "high risk agriculture" in the selected agriculture zone; high sensitivity of agricultural market to a possible deficit of yield. Results of our previous works (I, II), including application of this approach to the Medieval England wheat market (1250-1700) and to the modern USA durum market (1910-1992), showed that connection between wheat price bursts and space weather state in these cases was absolutely real. The aim of the present work is to answer the question why wheat markets in one selected region may be sensitive to a space weather factor, while in other regions wheat markets demonstrate absolutely indifferent reaction on the space weather. For this aim, we consider dependence of sensitivity of wheat markets to space weather as a function of their location in different climatic zones of Europe. We analyze a database of 95 European wheat markets from 14 countries for the 600-year period (1260-1912). We show that the observed sensitivity of wheat markets to space weather effects is controlled, first of all, by a type of predominant climate in different zones of agricultural production. Wheat markets in the Northern and, partly, in

Repression of violence at public meetings and sporting events within the European legal space

Full Text Available Violence and unbecoming behaviour at sporting events stand for a most acute problem in numerous European countries. However, the method and modes of its' repression have been determined within the frames of each country, that is its' national legislation. Thus, a wide range of various regulations referring to the distinctions of this type of violence can be spotted in legislative of each European country. Nevertheless, along with the development and maturing of the idea of the necessity of implementation of both international and regional legal instruments, used for setting up national law of individual states, a number of European legal instruments have also come to life. It comes as no surprise, though, the growing need for more both general and separate legal instruments in the repression of violence and unbecoming behaviour at sporting events in the European legislative. Based on the analysis, it is possible to single out the ones to achieve the strongest effect to our national legislative. Consequently, the general frames of the repression of violence and unbecoming behaviour at sporting events are founded on European Convention on Human Rights and Fundamental Freedoms (1950, whereas the separated ones lie in the Convention of the European Council on the Repression of Violence and Unbecoming Behaviour at Sporting Events, especially the soccer games, with the Recommendation (1985. The subject of this paper is based on analysis of the legal frames established by the European legal instruments in the field of the repression of violence and unbecoming behaviour at sporting events. The methodological framework throughout the research considers the usage of various methods: historical, linguistic, sociological, logical, normative, analysis of content, etc.

Fly me to the Sun! ESA inaugurates the European Project on the Sun

Science.gov (United States)

2000-11-01

In an initiative mounted by ECSITE (European Collaborative for Science, Industry and Technology Exhibitions) with funding from the European Commission and under the supervision, coordination and co-sponsorship of ESA, five teams of youngsters (16-18 years old) from Belgium, France, Germany, Italy and the Netherlands were selected and coordinated by European science museums from each of their countries (Musée des Sciences et des Techniques - Parentville, B; Cité de l'Espace - Toulouse, F; Deutsches Museum - Munich, D; Fondazione IDIS - Naples, I; Foundation Noordwijk Space Expo - Noordwijk, NL). The teams each focused on a theme related to solar research: "How does the Sun work?" (I), "The Sun as a star" (F), "Solar activity" (NL), "Observing the Sun" (D), "Humans and the Sun" (B), and built exhibition "modules" that they will present at the inauguration, in the context of European Science and Technology Week 2000 (6-10 November), promoted by the European Commission. During the two-day event, a jury of representatives of other European science and technology museums, ESA scientists, a science journalist, and two ESA astronauts (Frank de Winne and Andre Kuipers) will judge the youngsters' exhibition modules on the basis of their scientific correctness, their museological value and the commitment shown by the young "communication experts". The winning team will be officially announced on 9 November. The prize is a weekend at the Space Camp in Redu, Belgium. The objective of the European Project on the Sun is educational. It aims, through the direct and "fresh" involvement of youngsters, to heighten European citizens' awareness of space research in general and the Sun's influence on our daily lives in particular. The role of the European Space Agency as reference point in Europe for solar research has been fundamental to the project. From ESA's perspective, EPOS is part of this autumn's wider communication initiative called the Solar Season, which is highlighting ESA

Roles of Solar Power from Space for Europe - Space Exploration and Combinations with Terrestrial Solar Plant Concepts

Science.gov (United States)

Summerer, L.; Pipoli, T.; Galvez, A.; Ongaro, F.; Vasile, M.

The paper presents the prospective roles of SPS concepts for Europe, shows the outcome of recent studies undertaken by ESA's Advanced Concepts Team (ACT) together with European industry and research centres and gives insight into planned activities. The main focus is on the assessment of the principal validity and economic viability of solar power from space concepts in the light of advances in alternative sustainable, clean and potentially abundant solar-based terrestrial concepts. The paper takes into account expected changes in the European energy system (e.g. gradual introduction of hydrogen as energy vector). Special emphasis is given to the possibilities of integrating space and terrestrial solar plants. The relative geographic proximity of areas in North Africa with high average solar irradiation to the European energy consumer market puts Europe in a special position regarding the integration of space and terrestrial solar power concepts. The paper presents a method to optimise such an integration, taking into account different possible orbital constellations, terrestrial locations, plant number and sizes as well as consumer profiles and extends the scope from the European-only to a multi continental approach including the fast growing Chinese electricity market. The work intends to contribute to the discussion on long-term options for the European commitment to worldwide CO2 emission reduction. Cleaner electricity generation and environmentally neutral transport fuels (e.g. solar generated hydrogen) might be two major tools in reaching this goal.

THE EUROPEAN UNION’S QUEST FOR ENERGY POLICY: A GEO-ECONOMIC APPROACH

Directory of Open Access Journals (Sweden)

Alin Codoban

2011-09-01

Full Text Available The European Union’s external energy policy architecture is very important for further energy security and economic development. European normative power on its neighbours represents the most efficient way of integrating neighbouring energy markets, with the EU’s emerging internal market and, in perspective, through economic interdependence and complementarities, there are chances of creating an European geo-energy space. EU’s tools for shaping the geo-energy space are becoming more effective in an extended European economic area that would allow it to act as the main actor in a multilateral interconnected system of energy producer and transit countries. The result of the paper is materialized in a new paradigm for EU’s external energy policy, which can provide future security of supply through market institutions and an active economic diplomacy in the resource energy countries.

Haider, O.; Groemer, G.

2014-01-01

In September 2011, the European Space Agency (ESA) and the German Space Agency (DLR) organized the first European SpaceTweetup during the German Aerospace day. One of the authors was one of 60 participants at this SpaceTweetup in Cologne and experienced the concept of a Tweetup and the engagement of the participants from the inside view. Building upon this experience, the Austrian Space Forum (OeWF) organized the first Austrian MarsTweetup during the “Dachstein Mars analog simulation”. Between 27 Apr,2001 and May,2012, a five day Mars simulation was conducted by the Austrian Space Forum and international research partners at the Giant Ice caves at the Dachstein region in Austria. During this field test, the Aouda.X spacesuit simulator and selected geophysical and life-science related experiments were conducted. In this paper we outline the potential and limitations of social media and how to engage the general public to participate and communicate about space projects through their own experience. We show examples of material SpaceTweetup participants produced e.g. hundreds of tweets during the actual event, blog entries, photo galleries and how space communication can benefit from it. Our considerations on organizing a SpaceTweetup are complemented with a section on lessons learned.

Full Text Available National governments are keenly aware of the need for investment in space. Canada, as a formal cooperating state in the European Space Agency (ESA, and Germany, as a leading member state of ESA, are interlinked in Europe’s space endeavours. Beyond ESA, Germany and Canada additionally have a strong history of bilateral cooperation on a range of space projects. This paper discusses the novel interdependencies between clear national and now supranational space policies, using the examples of the Canada-European Union (EU Comprehensive Economic and Trade Agreement (CETA. The agreement covers most aspects of the EU-Canada bilateral economic relationship and includes space. The paper focuses on international space policies, strategic bilateral co-operation, and technical accomplishments. It takes a closer look at German-Canadian collaboration in space programs and offers some reflection on the effect of both the EU and ESA’S transatlantic involvement in space.

GMES capabilities include monitoring and forecasting of climatic change, flood risks, soil and coastal erosion, crop and fish resources, air pollution, greenhouse gases, iceberg distribution and snow cover, among others. To accomplish this, GMES has been divided into three main components: Space, In-situ and Services. The Space Component, led by ESA, comprises five types of new satellites called Sentinels that are being developed by ESA specifically to meet the needs of GMES, the first of which to be launched in 2013. These missions carry a range of technologies, such as radar and multi-spectral imaging instruments for land, ocean and atmospheric monitoring. In addition, access to data from the so-called Contributing Missions guarantees that European space infrastructure is fully used for GMES. An integrated Ground Segment ensures access to Sentinels and Contributing Missions data. The in-situ component, under the coordination of the European Environment Agency (EEA), is composed of atmospheric and Earth based monitoring systems, and based on established networks and programmes at European and international levels. The European Commission is in charge of implementing the services component of GMES and of leading GMES overall. GMES services, fed with data from the Space and In-situ components, will provide essential information in five main domains, atmosphere, ocean and land monitoring as well as emergency response and security. Climate change has been added

Prospects for future supernova surveys are discussed, focusing on the European Space Agency's Euclid mission and the European Extremely Large Telescope (E-ELT), both expected to be in operation around the turn of the decade. Euclid is a 1.2 m space survey telescope that will operate at visible and near-infrared wavelengths, and has the potential to find and obtain multi-band lightcurves for thousands of distant supernovae. The E-ELT is a planned, general-purpose ground-based, 40-m-class optical-infrared telescope with adaptive optics built in, which will be capable of obtaining spectra of type Ia supernovae to redshifts of at least four. The contribution to supernova cosmology with these facilities will be discussed in the context of other future supernova programmes such as those proposed for DES, JWST, LSST and WFIRST.

European Economic Community/the European energy conference

European Economic Community/the European energy conference (a meeting of the energy ministers of the nine member countries), held at Brussels on 3/27/79, was a continuation of the EEC Council meeting held at Paris on 3/12-13/79. Proposals for measures to be taken by the member countries included support for exploration, especially geophysical prospecting for oil off the east coast of Greenland, at a cost of 3.5 million units of account (UC); modification of the regulations for crude oil distribution among the EEC member countries in case of a supply crisis; a second series of 36 energy-conservation demonstration projects, to cost 15,626,320 UC and be undertaken in 1979-83; and the UK proposal to call for bids on the first series of 17 projects, costing 5,779,000 UC and adopted in Dec. 1978, before discussing the second series. Six of the 36 projects are French; they involve heat pumps and hybrid nuclear-electric vehicles and space-heating systems. A report on the current status of coal projects was given, and problems with fast-breeder reactors were discussed.

Cultural-Linguistic Globalization in the European Space

Sebastian Chirimbu

2011-05-01

Full Text Available Europe is a reality not only in economic and political terms mainly. The impact of globalization on contemporary European area is a contested subject in political debates, media or academically. Although occurring in the economic field with multiple meanings (the increase in economic interdependence of countries worldwide through increasing volume and variety of goods and services transactions across borders, in linguistics, globalization illustrates a particular facet of the relationship between the dynamics and needs of society communication. The impressive contemporary transformation processes triggered by globalization can be fully understood only if read in a cultural key, only if analyzed from a cultural perspective. At the same time, the multiple transformations modify the very structure of the cultural experience and affect the way we understand culture in the modern world. Globalization is the core of modern culture and cultural practices are the core of globalization.

Sagath, Daniel; Papadimitriou, Angeliki; Adriaensen, Maarten; Giannopapa, Christina

2018-01-01

The European Space Agency (ESA) has twenty-two Member States with a variety of governance structures and strategic priorities regarding their space activities. The objective of this paper is to provide an up-to date overview and a holistic assessment of the national space governance structures and strategic priorities of the eleven smaller Member States (based on annual ESA contributions). A link is made between the governance structure and the main strategic objectives. The specific needs and interests of small and new Member States in the frame of European Space Integration are addressed. The first part of the paper focuses on the national space governance structures in the eleven smaller ESA Member States. The governance models of these Member States are identified including the responsible ministries and the entities entrusted with the implementation of space strategy/policy and programmes of the country. The second part of this paper focuses on the content and analysis of the national space strategies and indicates the main priorities and trends in the eleven smaller ESA Member States. The priorities are categorised with regards to technology domains, the role of space in the areas of sustainability and the motivators for space investments. In a third and final part, attention is given to the specific needs and interests of the smaller Member States in the frame of European space integration. ESA instruments are tailored to facilitate the needs and interests of the eleven smaller and/or new Member States.

A socio-economic impact assessment of the European launcher sector

Science.gov (United States)

Monte, Luca del; Scatteia, Luigi

2017-08-01

In a context where the economic strains are challenging European policies as well as the very fabric of governmental contributions to public life, innovation and efficacy of public policy in research are called upon to support growth in Europe and to sustain employment and entrepreneurial capacities. Governments need evidence that the investments in space, while providing strategic tools to implement sovereign policies, create jobs and build the competitive European economy of the future. This is particularly true when the decisions at stake have a potential bearing on the future of the European space sector for at least the next 30 years, as it has been the case for the ESA Council at ministerial level meeting in December 2014. On that occasion, Ministers took the decision to start the development of a new Ariane 6 launcher and Vega evolutions having a critical bearing on the Member States' strategic industrial capabilities and on the sustainability of the European guaranteed access to space. Given the importance of the subject, and following similar studies undertaken in the past for e.g. the Ariane 1-4 programme, the Agency has requested an independent consulting team to perform a dedicated study to assess ex-post the direct, indirect and induced socio-economic impacts of the Ariane 5 programme (mid-term evaluation) and of the Vega programme (early evaluation) globally, at European level, and within the economies and industries of each ESA Member State. This paper presents the assessment of the socio-economic impacts allowing the evaluation of the return on public investments in launchers through ESA in a wider perspective, going beyond the purely economic terms. The scope of the assessment covered in total approximately 25 ESA programmatic and activity lines and 30,000 commitments from 1986 to end 2012. In the framework of the study, the economic impact of the European launcher programmes is measured through a GDP impact defined as the straight economic

The objective was to investigate autonomic control in groups of European and Chinese astronauts and to identify similarities and differences. Beat-to-beat heart rate and finger blood pressure, brachial blood pressure, and respiratory frequency were measured from 10 astronauts (five European taking part in three different space missions and five Chinese astronauts taking part in two different space missions). Data recording was performed in the supine and standing positions at least 10 days before launch, and 1, 3, and 10 days after return. Cross-correlation analysis of heart rate and systolic pressure was used to assess cardiac baroreflex modulation. A fixed breathing protocol was performed to measure respiratory sinus arrhythmia and low-frequency power of systolic blood pressure variability. Although baseline cardiovascular parameters before spaceflight were similar in all astronauts in the supine position, a significant increase in sympathetic activity and a decrease in vagal modulation occurred in the European astronauts when standing; spaceflight resulted in a remarkable vagal decrease in European astronauts only. Similar baseline supine and standing values for heart rate, mean arterial pressure, and respiratory frequency were shown in both groups. Standing autonomic control was based on a balance of higher vagal and sympathetic modulation in European astronauts. Post-spaceflight orthostatic tachycardia was observed in all European astronauts, whereas post-spaceflight orthostatic tachycardia was significantly reduced in Chinese astronauts. The basis for orthostatic intolerance is not apparent; however, many possibilities can be considered and need to be further investigated, such as genetic diversities between races, astronaut selection, training, and nutrition, etc.

Abubakar, B.

Although the space program as a whole is a true reflection of the level of achievement in human history in the field of Science and Technology, but it is also important to note that there are numbers of communities and societies on this earth that are ignorant about this great achievement, hence leading to the continuous diverting of Potential Astronomers, Aerospace Engineers and Astrologist to other disciplines, thereby undermining the development of the space program over time. It was in view of the above that this research was conducted and came up with the under listed Suggestions/Recommendations:- (1) The European Space Agency (ESA), National Aeronautic Space Agency (NASA) and the Russian Space Agency, should be organising and sponsoring public enlightenment conferences, seminars and workshops towards creating awareness and attracting Potential Astronomers and other Space Scientist mostly in the developing countries into the space program. (2) Esteemed organisations in space programs like NASA, ESA and others should be awarding scholarships to potential space scientist that lacks the financial capability to pursue studies in the field of space science from the developing countries. (3) The European Space Agency, National Aeronautic Space Agency and the Russian Space Agency, should open their offices for the development of the space program in the third world countries. I believe that if the above suggestions/recommendations are adopted and implemented it will lead to the development of the space program in general, otherwise the rate at which potential Astronomers, Aerospace Engineers and Astrologists will be diverting into other disciplines will ever remain on the increase. Thanks for listening.

Full Text Available The Center of Epidemiologic Studies Depression Scale (CES-D is a commonly used self-report scale to measure depressive symptoms in the general population. In the present study, the Dutch version of the CES-D was administered to a sample of 837 Dutch-speaking adults of Belgium to examine the factor structure of the scale. Using confirmatory factory analysis (CFA, four first-order models and two second-order models were tested, and the second-order factor model with three pairs of correlated error terms provided the best fit to the data. Second, five socio-demographic variables (age, gender, education level, relation status, and family history of depression were included as covariates to the second-order factor model to explore the associations between background characteristics and the latent factor depression using a multiple indicators and multiple causes (MIMIC approach. Age had a significantly negative effect on depression, but the effect was not substantial. Female gender, lower education level, being single or widowed, and having a family history of depression were found to be significant predictors of higher levels of depression symptomatology. Finally, percentile norms on the CES-D raw scores were provided for subgroups of gender by education level for the general Dutch-speaking adult population of Belgium.

Kidney transplantation is the therapy of choice for end-stage kidney disease. Graft's life span is shorter than expected due in part to the delayed diagnosis of various complications, specifically those related to silent progression. It is recognized that serum creatinine levels and proteinuria are poor markers of mild kidney lesions, which results in delayed clinical information. There are many investigation looking for early markers of graft damage. Decreasing kidney graft cortical microcirculation has been related to poor prognosis in kidney transplantation. Cortical capillary blood flow (CCBF) can be measured by real-time contrast-enhanced sonography (RT-CES). Our aim was to describe the natural history of CCBF over time under diverse conditions of kidney transplantation, to explore the influence of donor conditions and recipient events, and to determine the capacity of CCBF for predicting renal function in medium term. RT-CES was performed in 79 consecutive kidney transplant recipients during the first year under regular clinical practice. Cortical capillary blood flow was measured. Clinical variables were analyzed. The influence of CCBF has been determined by univariate and multivariate analysis using mixed regression models based on sequential measurements for each patient over time. We used a first-order autoregression model as the structure of the covariation between measures. The post-hoc comparisons were considered using the Bonferroni correction. The CCBF values varied significantly over the study periods and were significantly lower at 48 h and day 7. Brain-death donor age and CCBF levels showed an inverse relationship (r: -0.62, p<0.001). Living donors showed higher mean CCBF levels than brain-death donors at each point in the study. These significant differences persisted at month 12 (54.5 ± 28.2 vs 33.7 ± 30 dB/sec, living vs brain-death donor, respectively, p = 0.004) despite similar serum creatinine levels (1.5 ± 0.3 and 1.5 ± 0.5 mg/dL).

In Europe, the EC co-funded project FAST20XX aims at exploring the borderline between aviation and space by investigating suborbital vehicles. The main focus is the identification and mastering of critical technologies for such vehicles rather than the vehicle development itself. Besides the objectives and overall layout of the project, the paper addresses also the progress made during the first period of the project. Two vehicle concepts are considered. A first one is a space vehicle launched from an airplane providing a low-energy ballistic flight experience using hybrid propulsion. The second is a vertically starting two-stage rocket space vehicle system concept taken as a basis to identify the conditions and constraints experienced during high- energy suborbital ultra-fast transport. The paper mainly discusses the two actual reference vehicles and the technical aspects of prerequisites for commercial operation including safety, human spaceflight, business cases, environmental and legal issues.

Earth observations from space: History, promise, and reality. Executive summary

Science.gov (United States)

1995-01-01

In this report the Committee on Earth Studies (CES), a standing committee of the Space Studies Board (SSB) within the National Research Council (NRC), reviews the recent history (nominally from 1981 to 1995) of the U.S. earth observations programs that serve civilian needs. The principal observations programs examined are those of NASA and the National Oceanic and Atmospheric Administration (NOAA). The Air Force' s Defense Meteorological Satellite Program (DMSP) is discussed, but only from the perspective of its relationship to civil needs and the planned merger with the NOAA polar-orbiting system. The report also reviews the interfaces between the earth observations satellite programs and the major national and international environmental monitoring and research programs. The monitoring and research programs discussed are the U.S. Global Change Research Program (USGCRP), the International Geosphere-Biosphere Program (IGBP), the World Climate Research Program (WCRP), related international scientific campaigns, and operational programs for the sharing and application of environmental data. The purpose of this report is to provide a broad historical review and commentary based on the views of the CES members, with particular emphasis on tracing the lengthy record of advisory committee recommendations. Any individual topic could be the subject of an extended report in its own right. Indeed, extensive further reviews are already under way to that end. If the CES has succeeded in the task it has undertaken. This report will serve as a useful starting point for any such more intensive study. The report is divided into eight chapters: ( I ) an introduction, (2) the evolution of the MTPE, (3) its relationship to the USGCRP, (4) applications of earth observations data, (5) the role that smaller satellites can play in research and operational remote sensing, (6) earth system modeling and information systems, (7) a number of associated activities that contribute to the MTPE

Major depressive disorder (MDD) is moderately heritable, however genome-wide association studies (GWAS) for MDD, as well as for related continuous outcomes, have not shown consistent results. Attempts to elucidate the genetic basis of MDD may be hindered by heterogeneity in diagnosis. The Center for Epidemiological Studies Depression (CES-D) scale provides a widely used tool for measuring depressive symptoms clustered in four different domains which can be combined together into a total score but also can be analysed as separate symptom domains. We performed a meta-analysis of GWAS of the CES-D symptom clusters. We recruited 12 cohorts with the 20- or 10-item CES-D scale (32 528 persons). One single nucleotide polymorphism (SNP), rs713224, located near the brain-expressed melatonin receptor (MTNR1A) gene, was associated with the somatic complaints domain of depression symptoms, with borderline genome-wide significance (p discovery = 3.82 × 10-8). The SNP was analysed in an additional five cohorts comprising the replication sample (6813 persons). However, the association was not consistent among the replication sample (p discovery+replication = 1.10 × 10-6) with evidence of heterogeneity. Despite the effort to harmonize the phenotypes across cohorts and participants, our study is still underpowered to detect consistent association for depression, even by means of symptom classification. On the contrary, the SNP-based heritability and co-heritability estimation results suggest that a very minor part of the variation could be captured by GWAS, explaining the reason of sparse findings.

To counteract microgravity (µG)-induced adaptation, European Space Agency (ESA) astronauts on long-duration missions (LDMs) to the International Space Station (ISS) perform a daily physical exercise countermeasure program. Since the first ESA crewmember completed an LDM in 2006, the ESA countermeasure program has strived to provide efficient protection against decreases in body mass, muscle strength, bone mass, and aerobic capacity within the operational constraints of the ISS environment and the changing availability of on-board exercise devices. The purpose of this paper is to provide a description of ESA's individualised approach to in-flight exercise countermeasures and an up-to-date picture of how exercise is used to counteract physiological changes resulting from µG-induced adaptation. Changes in the absolute workload for resistive exercise, treadmill running and cycle ergometry throughout ESA's eight LDMs are also presented, and aspects of pre-flight physical preparation and post-flight reconditioning outlined. With the introduction of the advanced resistive exercise device (ARED) in 2009, the relative contribution of resistance exercise to total in-flight exercise increased (33-46 %), whilst treadmill running (42-33 %) and cycle ergometry (26-20 %) decreased. All eight ESA crewmembers increased their in-flight absolute workload during their LDMs for resistance exercise and treadmill running (running speed and vertical loading through the harness), while cycle ergometer workload was unchanged across missions. Increased or unchanged absolute exercise workloads in-flight would appear contradictory to typical post-flight reductions in muscle mass and strength, and cardiovascular capacity following LDMs. However, increased absolute in-flight workloads are not directly linked to changes in exercise capacity as they likely also reflect the planned, conservative loading early in the mission to allow adaption to µG exercise, including personal comfort issues

The International Space Station (ISS) is orbiting Earth at an altitude of around 400 km. It has been manned since November 2000 and currently has a permanent crew of six. On-board ISS science is done in a wide field of sciences, from fundamental physics to biology and human physiology. Many of the experiments utilize the unique conditions of weightlessness, but also the views of space and the Earth are exploited. ESA’s (European Space Agency) ELIPS (European Programme Life and Physical sciences in Space) manages some 150 on-going and planned experiments for ISS, which is expected to be utilized at least to 2020. This presentation will give a short introduction to ISS, followed by an overview of the science field within ELIPS and some resent results. The emphasis, however, will be on ISS experiments which are close to the research performed at CERN. Silicon strip detectors like ALTEA are measuring the flux of ions inside the station.

The European AstRoMap project (supported by the European Commission Seventh Framework Programme) surveyed the state of the art of astrobiology in Europe and beyond and produced the first European roadmap for astrobiology research. In the context of this roadmap, astrobiology is understood as the study of the origin, evolution, and distribution of life in the context of cosmic evolution; this includes habitability in the Solar System and beyond. The AstRoMap Roadmap identifies five research topics, specifies several key scientific objectives for each topic, and suggests ways to achieve all the objectives. The five AstRoMap Research Topics are • Research Topic 1: Origin and Evolution of Planetary Systems • Research Topic 2: Origins of Organic Compounds in Space • Research Topic 3: Rock-Water-Carbon Interactions, Organic Synthesis on Earth, and Steps to Life • Research Topic 4: Life and Habitability • Research Topic 5: Biosignatures as Facilitating Life Detection It is strongly recommended that steps be taken towards the definition and implementation of a European Astrobiology Platform (or Institute) to streamline and optimize the scientific return by using a coordinated infrastructure and funding system.

EUROPEAN CIVIL CODE BETWEEN DESIDERATUM AND REALITY

Liviu-Bogdan Ciucă

2015-11-01

Full Text Available The principle of priority and direct application of European rules in relation to the provisions that we find in the national legislation, once assumed at European level, it has generated debates and concerns about the usefulness of a single legal act in private law matters. The idea of European Civil Code, appeared somewhere in the early 80s, is becoming more current and triggers a justified and sustained interest. Considering that the civil legislation of Community Member is a legislation dominated by tradition and peculiarities of culture, religion and temper, the issue of a European Civil Code forms as a project generating discussions, restraints and even rejec tions of the Member States in relation to this proposal. The current system of European legislative acts that apply immediately and priority in EU member states remains only a temporary solution and which generates difficulties in interpretation and affects the utility of the enactment. Clarifications on the pros and cons to promote a European Civil Codex will be analyzed primarily in terms of law and, last but not least in terms of political perspective, taking into account the Community objectives undertaken by accession treaties and the need for a legislative norm, especially European, to be predictable, transparent, useful and accessible. This paper intends to submit to debate both current doctrinal arguments, the blocking of such an approach, based on the principle of autonomy and the peculiarities of the legal system of each Member State, but also considering the practical arguments and of simplification of rules met in a European Civil Code assumed and applicable in the European space.

Posfolklore: Raíces y globalización en la música popular chilena

González, Juan Pablo

2011-10-01

Full Text Available This article discusses the development of the concept of folk roots, introduced by Chilean singer-songwriters in the mid-seventies, as a strategy to legitimize their divergent practice from the norm of folklore in times of military rule. The institutionalization of this concept with the return of democracy in the early nineties and its continued tightening from a third generation of Chilean singersongwriters and bands derivatives from theater companies, allow us to discuss the problem of folk roots in times of globalization. We propose the concepts of posfolklore and hydroponic roots, attached to the trend of Chilean listeners and musicians to incorporate world music to their artistic practices and consumption. These concepts would facilitate the discussion of the mixing of influences in Chilean music and the consequent proliferation of intermediate rather than hegemonic identities in contemporary Chilean culture.

Este artículo aborda el desarrollo del concepto de raíz folklórica, introducido por cantautores chilenos a mediados de los años setenta, como estrategia para legitimar corrientes divergentes del folklore de la norma imperante en tiempos del régimen militar. La institucionalización de este concepto con el retorno a la democracia y su continuo tensionamiento desde una tercera generación de cantautores nacionales y desde los nuevos grupos musicales derivados de compañías teatrales, permite reflexionar sobre el problema de las raíces en tiempos de globalización. Se proponen los conceptos de posfolklore y de raíces hidropónicas, adscritos a la permanente tendencia del músico y del auditor chileno a incorporar músicas del mundo a su práctica y consumo musical. Estos conceptos permiten discutir las mezclas en la música chilena y la consiguiente multiplicación de identidades intermedias más que hegemónicas en la cultura chilena contemporánea.

Jankowski, Konrad S

2016-05-15

The study aimed to elucidate previously observed associations between morningness-eveningness and depressive symptomatology in university students. Relations between components of depressive symptomatology and morningness-eveningness were analysed. Nine hundred and seventy-four university students completed Polish versions of the Centre for Epidemiological Studies - Depression scale (CES-D; Polish translation appended to this paper) and the Composite Scale of Morningness. Principal component analysis (PCA) was used to test the structure of depressive symptoms. Pearson and partial correlations (with age and sex controlled), along with regression analyses with morning affect (MA) and circadian preference as predictors, were used. PCA revealed three components of depressive symptoms: depressed/somatic affect, positive affect, interpersonal relations. Greater MA was related to less depressive symptoms in three components. Morning circadian preference was related to less depressive symptoms in depressed/somatic and positive affects and unrelated to interpersonal relations. Both morningness-eveningness components exhibited stronger links with depressed/somatic and positive affects than with interpersonal relations. Three CES-D components exhibited stronger links with MA than with circadian preference. In regression analyses only MA was statistically significant for positive affect and better interpersonal relations, whereas more depressed/somatic affect was predicted by lower MA and morning circadian preference (relationship reversed compared to correlations). Self-report assessment. There are three groups of depressive symptoms in Polish university students. Associations of MA with depressed/somatic and positive affects are primarily responsible for the observed links between morningness-eveningness and depressive symptoms in university students. People with evening circadian preference whose MA is not lowered have less depressed/somatic affect. Copyright © 2016

Ariane: NASA's European rival

Science.gov (United States)

The successful test launch of two three-quarter ton satellites in the European Space Agency's (ESA) Ariane rocket last June firmly placed ESA in competition with NASA for the lucrative and growing satellite launching market. Under the auspices of the private (but largely French-government financed) Arianespace company, ESA is already attracting customers to its three-stage rocket by offering low costs.According to recent reports [Nature, 292, pp. 785 and 788, 1981], Arianespace has been able to win several U.S. customers away from NASA, including Southern Pacific Communications, Western Union, RCA, Satellite Television Corporation, and GTE. Nature [292, 1981] magazine in an article entitled ‘More Trouble for the Hapless Shuttle’ suggests that it will be possible for Ariane to charge lower prices for a launch than NASA, even with the space shuttle.

Full Text Available El objetivo de este artículo es analizar el acompañamiento durante la cesárea, por parte de una persona de confianza de la mujer, consagrado por la Ley nº 17.386 de “acompañamiento en el parto”, aprobada en Uruguay en el año 2001. Los resultados forman parte de una investigación mayor sobre la vivencia y el significado de la cesárea para las mujeres que pasaron por esta experiencia. Para ello se optó por una metodología cualitativa de carácter exploratorio y descriptivo. La técnica utilizada fue la entrevista en profundidad, realizada a un total de 31 mujeres, cuyas cesáreas tuvieron lugar en su primera gestación, en Montevideo y área metropolitana (Uruguay. De los resultados obtenidos, se concluye que el acompañamiento en el proceso de trabajo de parto y nacimiento es vivido por las mujeres como un factor de protección emocional ante las ansiedades que genera la experiencia de una cirugía mayor como es la cesárea. Sin embargo, para las mujeres entrevistadas, el “acompañamiento” más que continuo se caracterizó por una serie de separaciones, tanto de sus acompañantes, como de sus hijos/as, lo cual provocó ansiedad, angustia, sentimientos de ambivalencia ante el recién nacido, dificultades en el establecimiento del vínculo materno-filial, sobre todo en el puerperio inmediato.

Un inventaire des principaux groupes de végétaux concernés, considérés comme des « espèces à risque de prolifération » a été dressé après examen de divers constats recensés sur le territoire français. Ce sont notamment des macro-algues, des cyanobactéries, des phanérogames hydrophytes autochtones comme Ranunculus sp., Potamogeton sp., Myriophyllum sp., Ceratophyllum sp., Lemna sp., et des hydrophytes introduits comme Elodea sp., Lagarosiphon sp., Ludwigia sp., Myriophyllum aquaticum, certains hélophytes et deux espèces rivulaires exotiques (Fallopia japonica et Impatiens glandulifera. Leurs potentialités importantes de développement et de propagation s’expliquent par leurs stratégies biologiques, dont certaines adaptations morphologiques et physiologiques et divers moyens de multiplication végétative. Les milieux propices aux proliférations présentent des conditions environnementales particulières : fort éclairement souvent lié à une faible profondeur et à un échauffement des eaux, conditions hydrologiques stables, minéralisation moyenne à forte, niveau trophique souvent élevé. La conjonction de ces deux composantes (espèce à risque et milieu propice, crée ainsi les conditions d’une prolifération et définit des situations à risque minimal ou maximal.

To examine the association between life-space mobility and different dimensions of depressive symptoms among older community-dwelling people. Cross-sectional analyses of baseline data of the 'Life-Space Mobility in Old Age' cohort study were carried out. The participants were community-dwelling women and men aged 75-90 years (N = 848). Data were gathered via structured interviews in participants' home. Life-space mobility (the University of Alabama at Birmingham (UAB) Life-Space Assessment - questionnaire) and depressive symptoms (Centre for Epidemiological Studies Depression Scale, CES-D) were assessed. Other factors examined included sociodemographic factors, difficulties walking 500 m, number of chronic diseases and the sense of autonomy in participation outdoors (subscale of Impact on Participation and Autonomy questionnaire). Poorer life-space mobility was associated with higher prevalence of different dimensions of depressive symptoms. The associations were partially mediated through walking difficulties, health and the sense of autonomy in participation outdoor activities. Poorer life-space mobility interrelates with higher probability for depressive symptoms, thus compromising older adults' mental wellbeing. A focus on older adults' life-space mobility may assist early identification of persons, who have elevated risk for depressive symptoms. The association between life-space mobility and depressive symptoms should be studied further utilizing longitudinal study designs to examine temporality and potential causality.

For this brief version, several authors supported a two-factor structure - Negative and Positive affect - but the relationship between the two reversed-worded items of the Positive affect factor could be better accounted for by correlated errors. The aim of this study is triple: firstly to test a French version of the CES-D10 among adolescents; secondly to test the relevance of a one-dimensional structure by considering error correlation for Positive affect items; finally to examine the extent to which this structural model is invariant across gender. The sample was composed of 269 French middle school adolescents (139 girls and 130 boys, mean age: 13.8, SD=0.65). Confirmatory Factorial Analyses (CFA) using the LISREL 8.52 were conducted in order to assess the adjustment to the data of three factor models: a one-factor model, a two-factor model (Positive and Negative affect) and a one-factor model with specification of correlated errors between the two reverse-worded items. Then, multigroup analysis was conducted to test the scale invariance for girls and boys. Internal consistency of the CES-D10 was satisfying for the adolescent sample (α=0.75). The best fitting model is the one-factor model with correlated errors between the two items of the previous Positive affect factor (χ(2)/dl=2.50; GFI=0.939; CFI=0.894; RMSEA=0.076). This model presented a better statistical fit to the data than the one-factor model without error correlation: χ(2)(diff) (1)=22.14, pstatistic for the model with equality-constrained factor loadings was 121.31. The change in the overall Chi(2) is not statistically significant. This result implies that the model is

The adjustment of the course of transport routes to the distribution of the population and the country’s land development (including economic potential and logistic infrastructure was outlined using measurements of cumulative accessibility. The results were presented in both cartographic form (isochrone approach and tabular form (cumulative approach. Research was conducted adopting different forms of transport used for relocation (including foot traffic, car, rail and multimodal transport and both the current and target layout of the transport network. This made it possible to determine the changes that will effectively run the process of investment in transport infrastructure on Polish territory. This allowed the identification of the areas of Poland which are particularly conveniently located in relation to domestic connections (in terms of the international network and those for which the European transport network remains difficult to access.

Space strategy for Europe and the International Lunar Decade

Beldavs, VZ

2017-09-01

The 2020-2030 decade offers extraordinary opportunity for the European space sector that is largely not recognized in present space strategy which does not recognize commercial space activities beyond communications satellites, launchers, and earth observation and navigation and downstream activities. Lunar and cislunar development can draw on the extensive experience of Europe in mining, clean energy, ecological systems as well as deep experience in managing the development of technologies through TRL1 through commercial sale via Horizon 2020 and previous Framework programs. The EU has unrivalled experience in coordinating research and advanced technology development from research centers, major firms and SMEs across multiple sovereign states. This capacity to coordinate across national boundaries can be a significant contribution to a global cooperative program like the International Lunar Decade. This paper will present a European space strategy for beyond 2020 and how this can mesh with the International Lunar Decade.

Writing the History of Space Missions: Rosetta and Mars Express

Science.gov (United States)

Coradini, M.; Russo, A.

2011-10-01

Mars Express is the first planetary mission accomplished by the European Space Agency (ESA). Launched in early June 2003, the spacecraft entered Mars's orbit on Christmas day of that year, demonstrating the new European commitment to planetary exploration. Following a failed attempt in the mid-­-1980s, two valid proposals for a European mission to Mars were submitted to ESA's decision-­-making bodies in the early 1990s, in step with renewed international interest in Mars exploration. Both were rejected, however, in the competitive selection process for the agency's Science Programme. Eventually, the Mars Express proposal emerged during a severe budgetary crisis in the mid-­-1990s as an exemplar of a "flexible mission" that could reduce project costs and development time. Its successful maneuvering through financial difficulties and conflicting scientific interests was due to the new management approach as well as to the public appeal of Mars exploration. In addition to providing a case study in the functioning of the ESA's Science Programme, the story of Mars Express discussed in this paper provides a case study in the functioning of the European Space Agency's Science Programme and suggests some general considerations on the peculiar position of space research in the general field of the history of science and technology.

ConnectinGEO (Coordinating an Observation Network of Networks EnCompassing saTellite and IN-situ to fill the Gaps in European Observations" is an H2020 Coordination and Support Action with the primary goal of linking existing Earth Observation networks with science and technology (S&T) communities, the industry sector, the Group on Earth Observations (GEO), and Copernicus. The project will end in February 2017. ConnectinGEO will initiate a European Network of Earth Observation Networks (ENEON) that will encompass space-based, airborne and in-situ observations networks. ENEON will be composed of project partners representing thematic observation networks along with the GEOSS Science and Technology Stakeholder Network, GEO Communities of Practices, Copernicus services, Sentinel missions and in-situ support data representatives, representatives of the European space-based, airborne and in-situ observations networks. This communication presents the complex panorama of Earth Observations Networks in Europe. The list of networks is classified by discipline, variables, geospatial scope, etc. We also capture the membership and relations with other networks and umbrella organizations like GEO. The result is a complex interrelation between networks that can not be clearly expressed in a flat list. Technically the networks can be represented as nodes with relations between them as lines connecting the nodes in a graph. We have chosen RDF as a language and an AllegroGraph 3.3 triple store that is visualized in several ways using for example Gruff 5.7. Our final aim is to identify gaps in the EO Networks and justify the need for a more structured coordination between them.

In 2005 the then ESA Directorate for Human Spaceflight, Microgravity and Exploration (D-HME) commissioned a study from the European Science Foundation's (ESF) European Space Sciences Committee (ESSC) to examine the science aspects of the Aurora Programme in preparation for the December 2005 Ministerial Conference of ESA Member States, held in Berlin. A first interim report was presented to ESA at the second stakeholders meeting on 30 and 31 May 2005. A second draft report was made available at the time of the final science stakeholders meeting on 16 September 2005 in order for ESA to use its recommendations to prepare the Executive proposal to the Ministerial Conference. The final ESSC report on that activity came a few months after the Ministerial Conference (June 2006) and attempted to capture some elements of the new situation after Berlin, and in the context of the reduction in NASA's budget that was taking place at that time; e.g., the postponement sine die of the Mars Sample Return mission. At the time of this study, ESSC made it clear to ESA that the timeline imposed prior to the Berlin Conference had not allowed for a proper consultation of the relevant science community and that this should be corrected in the near future. In response to that recommendation, ESSC was asked again in the summer of 2006 to initiate a broad consultation to define a science-driven scenario for the Aurora Programme. This exercise ran between October 2006 and May 2007. ESA provided the funding for staff support, publication costs, and costs related to meetings of a Steering Group, two meetings of a larger ad hoc group (7 and 8 December 2006 and 8 February 2007), and a final scientific workshop on 15 and 16 May 2007 in Athens. As a result of these meetings a draft report was produced and examined by the Ad Hoc Group. Following their endorsement of the report and its approval by the plenary meeting of the ESSC, the draft report was externally refereed, as is now normal practice

Economic Benefits of Space Tourism to Europe

Science.gov (United States)

Collins, P.

The European aerospace industry has been very slow to consider the commercial opportunities in supplying passenger space travel services. This has been a costly mistake not just of space policy, but also of economic policy and environmental policy. This is because it is very unlikely that space tourism will remain just a small-scale activity of the very rich; it is much more likely to grow into a major new industry, employing millions of people in high quality employment - eventually much of it outside the Earth's eco-system. This is particularly important because, although the European “social-economic model” has greater popular support than the “USA model” (including among the general USA population), Europe today faces the major problem of high unemployment, which is imposing heavy social and economic costs. If Europe makes serious efforts soon to encourage the growth of passenger space travel, and of the many other economically and environmentally valuable space activities to which this will lead, then commercial space activities could become a major new axis of economic growth and employment-creation for Europe. Moreover, Europe has several advantages over the USA, Russia, Japan, China and India, and so could play a leading role in this field, if policy errors are corrected. The paper discusses the above possibilities, and the potential economic, environmental and other benefits for Europe in investing boldly in this fledgling industry.

The EU-led Copernicus programme is one of the most ambitious, most comprehensive Earth observation systems world-wide. It aims at giving decision-makers reliable and up-to-date information to coordinate policy areas and formulate strategies relating to the environment, at global, continental, national and regional level. It is led by the European Union (EU), with the European Space Agency (ESA) as the main partner.Copernicus has now entered into its operational phase with four satellites already launched (Sentinel-1 A/B, Sentinel-2 A and Sentinel-3 A) and information services up and running in the environmental domains. However, new priorities and new societal needs have been introduced in the EU policies, and Copernicus has to respond to them in a quick and efficient way by expanding the Copernicus observation infrastructure, while guaranteeing the necessary continuity of observations and services.The European Commission and ESA issued now a roadmap for this evolution process, which will implement the required transition from research and development to operations of some new candidate missions.This presentation will give an overview of the current status and future perspectives of the Copernicus space component.

The multi-user facility EXPOSE-E was designed by the European Space Agency to enable astrobiology research in space (low-Earth orbit). On 7 February 2008, EXPOSE-E was carried to the International Space Station (ISS) on the European Technology Exposure Facility (EuTEF) platform in the cargo bay of Space Shuttle STS-122 Atlantis. The facility was installed at the starboard cone of the Columbus module by extravehicular activity, where it remained in space for 1.5 years. EXPOSE-E was returned to Earth with STS-128 Discovery on 12 September 2009 for subsequent sample analysis. EXPOSE-E provided accommodation in three exposure trays for a variety of astrobiological test samples that were exposed to selected space conditions: either to space vacuum, solar electromagnetic radiation at >110 nm and cosmic radiation (trays 1 and 3) or to simulated martian surface conditions (tray 2). Data on UV radiation, cosmic radiation, and temperature were measured every 10 s and downlinked by telemetry. A parallel mission ground reference (MGR) experiment was performed on ground with a parallel set of hardware and samples under simulated space conditions. EXPOSE-E performed a successful 1.5-year mission in space.

The possibility of aromorphosis in further development of closed human life support systems using genetically modified organisms

Science.gov (United States)

Gitelson, Josef

Creation of closed systems that would be able to support human life outside the biosphere for extended periods of time (CES) was started after humans went into outer space. The last fifty years have seen the construction of experimental variants of the CES in Russia, USA, and Japan. The "MELISSA" project of the European Space Agency is being prepared to be launched. Much success has been achieved in closing material loops in the CES. An obstacle to constructing a fully closed ecosystem is significant imbalance in material exchange between the producing components and the decomposing ones in the CES. The spectrum of metabolites released by humans does not fully correspond to the requirements of the main producer of the CES -plants. However, this imbalance can be corrected by rather simple physicochemical processes that can be used in the CES without unclosing the system. The major disagreement that prevents further improvement of human life support systems (LSS) is that the spectrum of products of photosynthesis in the CES does not correspond to human food requirements qual-itatively, quantitatively, or in terms of diversity. In the normal, physiologically sound, human diet, this discrepancy is resolved by adding animal products. However, there are technical, technological, and hygienic obstacles to including animals in the closed human life support systems, and if higher animals are considered, there are also ethical arguments. If between the photoautotrophic link, plants, and the heterotrophic link, the human, there were one more heterotrophic link, farm animals, the energy requirements of the system would be increased by nearly an order of magnitude, decreasing its efficiency and making it heavier and bulkier. Is there another way to close loops in human life support systems? In biology, such "findings" of evolution, which open up new perspectives and offer ample opportunities for possible adapta-tions, are termed aromorphoses (Schmalhausen, 1948). In further

Socialdemocracia y capital: las raíces neoclásicas del modelo sueco

Full Text Available La socialdemocracia ha tenido en el Modelo Sueco su referente por antonomasia. Sin embargo, las raíces teóricas de esta experiencia histórica, lejos de implementar los principios típicos del keynesianismo, se asentaron sobre unas bases de marcado carácter neoclásico. A través del conocido como Modelo Rehn-Meidner, posteriormente afianzado por el llamado Modelo EFO, la socialdemocracia sueca estableció un marco de política fiscal y monetaria restrictiva en el que se desarrolló una política salarial solidaria cimentada en un poderoso sindicalismo y un sólido sistema corporativista de negociación colectiva centralizada. Así, mediante la paulatina igualación y la contención de los salarios, se buscaba estimular la productividad, mantener a raya los costes laborales y facilitar la concentración y la centralización del capital. El objetivo final era favorecer la competitividad del sector exportador sueco con el fin de asegurar una rentabilidad y un ritmo de acumulación adecuados.

Americium-241 radioisotope thermoelectric generator development for space applications

International Nuclear Information System (INIS)

Ambrosi, Richard; Williams, Hugo; Samara-Ratna, Piyal

2013-01-01

Space nuclear power systems are under development in the UK in collaboration with European partners as part of a European Space Agency (ESA) programme. Radioisotope thermoelectric generators (RTG) are an important element of this new capability in Europe. RTG systems being developed in Europe are targeting the 10 W electric to 50 W electric power generation range adopting a modular scalable approach to the design. Radiogenic decay heat from radioisotopes can be converted to electrical power by using appropriate semiconductor based thermoelectric materials. The plan for Europe is to develop radioisotope space nuclear power systems based on both thermoelectric and Stirling power conversion systems. Although primarily focused on delivering up to 50 W of electrical power, the European radioisotope thermoelectric system development programme is targeting americium-241 as a fuel source and is maximizing the use of commercially available thermoelectric manufacturing processes in order to accelerate the development of power conversion systems. The use of americium provides an economic solution at high isotopic purity and is product of a separation process from stored plutonium produced during the reprocessing of civil nuclear fuel. A laboratory prototype that uses electrical heating as a substitute for the radioisotope was developed to validate the designs. This prototype has now been tested. This paper outlines the requirements for a European americium-241 fuelled RTG, describes the most recent updates in system design and provides further insight into recent laboratory prototype test campaigns.

Aircraft parabolic flights repetitively provide up to 23 seconds of reduced gravity during ballistic flight manoeuvres. Parabolic flights are used to conduct short microgravity investigations in Physical and Life Sciences and in Technology, to test instrumentation prior to space flights and to train astronauts before a space mission. The use of parabolic flights is complementary to other microgravity carriers (drop towers, sounding rockets), and preparatory to manned space missions on board the International Space Station and other manned spacecraft, such as Shenzhou and the future Chinese Space Station. After 17 years of using the Airbus A300 ZERO-G, the French company Novespace, a subsidiary of the ' Centre National d'Etudes Spatiales' (CNES, French Space Agency), based in Bordeaux, France, purchased a new aircraft, an Airbus A310, to perform parabolic flights for microgravity research in Europe. Since April 2015, the European Space Agency (ESA), CNES and the ` Deutsches Zentrum für Luft- und Raumfahrt e.V.' (DLR, the German Aerospace Center) use this new aircraft, the Airbus A310 ZERO-G, for research experiments in microgravity. The first campaign was a Cooperative campaign shared by the three agencies, followed by respectively a CNES, an ESA and a DLR campaign. This paper presents the new Airbus A310 ZERO-G and its main characteristics and interfaces for scientific experiments. The experiments conducted during the first European campaign are presented.

For decades experiments conducted on space stations like MIR and the ISS have been gathering data in many fields of research in the natural sciences, medicine and engineering. The European Union-sponsored ULISSE project focused on exploring the wealth of unique experimental data provided by revealing raw and metadata from these studies via an Internet Portal. This book complements the portal. It serves as a handbook of space experiments and describes the various types of experimental infrastructure areas of research in the life and physical sciences and technology space missions that hosted scientific experiments the types and structures of the data produced and how one can access the data through ULISSE for further research. The book provides an overview of the wealth of space experiment data that can be used for additional research and will inspire academics (e.g. those looking for topics for their PhD thesis) and research departments in companies for their continued development.

Exploiting Orbital Data and Observation Campaigns to Improve Space Debris Models

Science.gov (United States)

Braun, V.; Horstmann, A.; Reihs, B.; Lemmens, S.; Merz, K.; Krag, H.

The European Space Agency (ESA) has been developing the Meteoroid and Space Debris Terrestrial Environment Reference (MASTER) software as the European reference model for space debris for more than 25 years. It is an event-based simulation of all known individual debris-generating events since 1957, including breakups, solid rocket motor firings and nuclear reactor core ejections. In 2014, the upgraded Debris Risk Assessment and Mitigation Analysis (DRAMA) tool suite was released. In the same year an ESA instruction made the standard ISO 24113:2011 on space debris mitigation requirements, adopted via the European Cooperation for Space Standardization (ECSS), applicable to all ESA missions. In order to verify the compliance of a space mission with those requirements, the DRAMA software is used to assess collision avoidance statistics, estimate the remaining orbital lifetime and evaluate the on-ground risk for controlled and uncontrolled reentries. In this paper, the approach to validate the MASTER and DRAMA tools is outlined. For objects larger than 1 cm, thus potentially being observable from ground, the MASTER model has been validated through dedicated observation campaigns. Recent campaign results shall be discussed. Moreover, catalogue data from the Space Surveillance Network (SSN) has been used to correlate the larger objects. In DRAMA, the assessment of collision avoidance statistics is based on orbit uncertainty information derived from Conjunction Data Messages (CDM) provided by the Joint Space Operations Center (JSpOC). They were collected for more than 20 ESA spacecraft in the recent years. The way this information is going to be used in a future DRAMA version is outlined and the comparison of estimated manoeuvre rates with real manoeuvres from the operations of ESA spacecraft is shown.

The European XFEL bunch compressor system has been optimized for greater flexibility in parameter space. Operation beyond the XFEL design parameters is discussed in two directions: achieving the uppermost number of photons in a single pulse on one hand and reaching the necessary peak current for lasing with a pulse as short as possible on the other. Results of start-to-end calculations including 3D-CSR effects, space charge forces and the impact on wake fields demonstrate the potential of the XFEL for further improvement or, respectively, its safety margin for operation at design values.

A prototype instrument, under development at the University of Leicester, for the future European Space Agency (ESA) ExoMars mission, was used for the analysis of microbial pigments within a stratified gypsum crust from a hypersaline saltern evaporation pond at Eilat (Israel). Additionally, the same samples were analysed using a miniaturized Raman spectrometer, featuring the same 532 nm excitation. The differences in the position of the specific bands, attributed to carotenoid pigments from different coloured layers, were minor when analysed by the ESA prototype instrument; therefore, making it difficult to distinguish among the different pigments. The portable Delta Nu Advantage instrument allowed for the discrimination of microbial carotenoids from the orange/green and purple layers. The purpose of this study was to complement previous laboratory results with new data and experience with portable or handheld Raman systems, even with a dedicated prototype Raman system for the exploration of Mars. The latter is equipped with an excitation wavelength falling within the carotenoid polyene resonance region. The ESA prototype Raman instrument detected the carotenoid pigments (biomarkers) with ease, although further detailed distinctions among them were not achieved. PMID:25368354

Full Text Available The analysis of remote sensing data to assess geohazards is being improved by web-based platforms and collaborative projects, such as the Geohazard Exploitation Platform (GEP of the European Space Agency (ESA. This paper presents the evaluation of a surface velocity map that is generated by this platform. The map was produced through an unsupervised Multi-temporal InSAR (MTI analysis applying the Parallel-SBAS (P-SBAS algorithm to 25 ENVISAT satellite images from the South of Spain that were acquired between 2003 and 2008. This analysis was carried out using a service implemented in the GEP called “SBAS InSAR”. Thanks to the map that was generated by the SBAS InSAR service, we identified processes not documented so far; provided new monitoring data in places affected by known ground instabilities; defined the area affected by these instabilities; and, studied a case where GEP could have been able to help in the forecast of a slope movement reactivation. This amply demonstrates the reliability and usefulness of the GEP, and shows how web-based platforms may enhance the capacity to identify, monitor, and assess hazards that are associated to geological processes.

1995-02-01

During the past six months, many astronomers - observational as well theoretical - have been busy interpreting the many data taken during the impacts and thereafter. This is a very labour-intensive task and although the first conclusions have begun to emerge, it has also become obvious that extensive consultations between the various groups are necessary before it will be possible to understand the very complex processes during the impacts and thereafter. In order to further the interaction among the involved scientists, it has been decided to hold a three-day "European SL-9/Jupiter Workshop" at the Headquarters of the European Southern Observatory. More than 100 astronomers will meet on February 13-15, 1995, and close to 100 reports will be delivered on this occasion. Although most come from European countries, the major groups on other continents are also well represented. This meeting will give the participants the opportunity to exchange information about their individual programmes and will serve to establish future collaborative efforts. SL-9/JUPITER PRESS CONFERENCE In this connection, ESO is pleased to invite the media to a Press Conference: Wednesday, February 15, 1995, 17:30 CET ESO Headquarters, Karl-Schwarzschild-Strasse 2, D-85748 Garching, Germany This conference will be held at the end of the Workshop and will provide a thorough overview of the latest results, as presented during the meeting. Media representatives who are interested in participating in this Press Conference are requested to register with the ESO Information Service (Mrs. E.

Although the Gelidiales are economically important marine red algae producing agar and agarose, the phylogeny of this order remains poorly resolved. The present study provides a molecular phylogeny based on a novel marker, nuclear-encoded CesA, plus plastid-encoded psaA, psbA, rbcL, and mitochondria-encoded cox1 from subsets of 107 species from all ten genera within the Gelidiales. Analyses of individual and combined datasets support the monophyly of three currently recognized families, and reveal a new clade. On the basis of these results, the new family Orthogonacladiaceae is described to accommodate Aphanta and a new genus Orthogonacladia that includes species previously classified as Gelidium madagascariense and Pterocladia rectangularis. Acanthopeltis is merged with Gelidium, which has nomenclatural priority. Nuclear-encoded CesA was found to be useful for improving the resolution of phylogenetic relationships within the Gelidiales and is likely to be valuable for the inference of phylogenetic relationship among other red algal taxa.

Flax, Linum usitatissimum L., is a valuable multi-purpose plant, and currently, its genome is being extensively investigated. Nevertheless, mapping of genes in flax genome is still remaining a challenging task. The cellulose synthase ( CesA ) multigene family involving in the process of cellulose synthesis is especially important for metabolism of this fiber crop. For the first time, fluorescent in situ hybridization (FISH)-based chromosomal localization of the CesA conserved fragment (KF011584.1), 5S, and 26S rRNA genes was performed in landrace, oilseed, and fiber varieties of L. usitatissimum . Intraspecific polymorphism in chromosomal distribution of KF011584.1 and 5S DNA loci was revealed, and the generalized chromosome ideogram was constructed. Using BLAST analysis, available data on physical/genetic mapping and also whole-genome sequencing of flax, localization of KF011584.1, 45S, and 5S rRNA sequences on genomic scaffolds, and their anchoring to the genetic map were conducted. The alignment of the results of FISH and BLAST analyses indicated that KF011584.1 fragment revealed on chromosome 3 could be anchored to linkage group (LG) 11. The common LG for 45S and 5S rDNA was not found probably due to the polymorphic localization of 5S rDNA on chromosome 1. Our findings indicate the complexity of integration of physical, genetic, and cytogenetic mapping data for multicopy gene families in plants. Nevertheless, the obtained results can be useful for future progress in constructing of integrated physical/genetic/cytological maps in L. usitatissimum which are essential for flax breeding.

The Space House TM : Space Technologies in Architectural Design

Science.gov (United States)

Gampe, F.; Raitt, D.

2002-01-01

The word "space" has always been associated with and had a profound impact upon architectural design. Until relatively recently, however, the term has been used in a different sense to that understood by the aerospace community - for them, space was less abstract, more concrete and used in the context of space flight and space exploration, rather than, say, an empty area or space requiring to be filled by furniture. However, the two senses of the word space have now converged to some extent. Interior designers and architects have been involved in designing the interior of Skylab, the structure of the International Space Station, and futuristic space hotels. Today, architects are designing, and builders are building, houses, offices and other structures which incorporate a plethora of new technologies, materials and production processes in an effort not only to introduce innovative and adventurous ideas but also in an attempt to address environmental and social issues. Foremost among these new technologies and materials being considered today are those that have been developed for and by the space industry. This paper examines some of these space technologies, such as energy efficient solar cells, durable plastics, air and water filtration techniques, which have been adapted to both provide power while reducing energy consumption, conserve resources and so on. Several of these technologies have now been employed by the European Space Agency to develop a Space House TM - the first of its kind, which will be deployed not so much on planets like Mars, but rather here on Earth. The Space House TM, which exhibits many innovative features such as high strength light-weight carbon composites, active noise-damped, (glass and plastic) windows, low-cost solar arrays and latent heat storage, air and water purification systems will be described.

The Austrian Space Plan

Science.gov (United States)

Pseiner, K.; Balogh, W.

2002-01-01

After several years of preparation and discussion among the involved players, the Austrian Space Plan was approved for implementation in November 2001. Based on careful benchmarking and analysis of the capabilities of the Austrian space sector it aims to create excellent conditions for the sector's further development. The new space strategy embraces Austria's participation in the mandatory and optional programmes of the European Space Agency and establishes a National Space Programme supported by separate funding opportunities. A set of clearly-defined indicators ensures that the progress in implementing the Space Plan can be objectively judged through independent, annual reviews. The National Space Programme promotes international cooperation in space research and space activities with the aim to strengthen the role of space science and to better prepare Austrian space industry for the commercial space market. In the framework of the Space Plan the Austrian Space Agency has been tasked with integrating the industry's growing involvement in aeronautics activities to better utilize synergies with the space sector. This paper reviews the various steps leading to the approval of the new space strategy and discusses the hurdles mastered in this process. It reports on the Space Plan's first results, specifically taking into account projects involving international cooperation. For the first the Austria aerospace-sector can rely on an integrated strategy for aeronautics- and space activities which is firmly rooted in the efforts to enhance the country's R&D activities. It may also act as a useful example for other small space- using countries planning to enhance their involvement in space activities.

Olmedo, E.; Sánchez Ortiz, Noelia; Lerate, Mercedes; Belló-Mora, Miguel; Klinkrad, H.

2009-10-01

A growing interest exists in a future, autonomous European Space Surveillance System (ESSS). Currently, most of the knowledge about Earth-orbiting space objects is based on information provided by the USASPACECOM. This paper presents the required initial orbit determination (IOD) and correlation techniques to process optical measurements. Former studies were focused on the handling of radar measurements, which are summarised with the aim of describing a global procedure for processing hybrid measurement types (combination of radar and optic data for catalogue maintenance). The introduction of manoeuvres are presented due to their importance in the space object catalogue maintenance. The detection of uncatalogued objects and the successful correlation of already catalogued objects involve two different tasks for telescopes: survey and tasking. Assumptions for both strategies are developed on the basis of the previous work developed at the University of Berne (see [T. Flohrer, T. Schildknecht, R. Musci, E. Stöveken, Performance estimation for GEO space surveillance, Advances in Space Research 35 (2005). [1]; T. Flohrer, T. Schildknecht, R.

Silica aerogels have been produced in large and transparent blocks for space astrophysics experiments since the beginning of the 1970's. They were used in cosmic ray experiments on board balloons by the Saclay group. A new space venture where aerogel Cerenkov radiators will play a decisive role is currently being prepared by a large collaboration of European and US Institutes. It will be part of the so-called International Solar Polar Mission (ISPM) which will explore the heliosphere over the full range of solar latitudes from the ecliptic (equatorial) plane to the magnetic poles of the sun. Comments on properties and long term behaviour of silica aerogel cerenkov radiators in space environment are given

Regulating private human suborbital flight at the international and European level: Tendencies and suggestions

Masson-Zwaan, Tanja; Moro-Aguilar, Rafael

2013-12-01

In the context of the FAST20XX project (Future High-Altitude High-Speed Transport) that started in 2009 under the 7th Framework Programme of the European Union (EU), the authors reexamined the legal status of private human suborbital flight, and researched whether it might be regulated as aviation or as spaceflight. International space law is ambiguous as to accommodating suborbital activities. While some provisions of the UN outer space treaties would seem to exclude them, generally there is not any explicit condition in terms of reaching orbit as a requirement for application. International air law presents equal difficulties in dealing with this activity. The classic definition of "aircraft" as contained in the Annexes to the Chicago Convention does not really encompass the kind of rocket-powered vehicles that are envisaged here. As a result, it is unclear whether the United Nations Committee on the Peaceful Uses of Outer Space (COPUOS), the International Civil Aviation Organization (ICAO), or both could be involved in an eventual international regulation of suborbital flight. In the absence of a uniform international regime, each state has the sovereign right to regulate human suborbital flights operating within its airspace. So far, two practical solutions have been realised or proposed, and will be analyzed. On the one hand, the USA granted power for regulation and licensing over private human suborbital flight to the Office of Commercial Space Transportation of the Federal Aviation Administration (FAA/AST). Subsequent regulations by the FAA have set out a series of requirements for companies that want to operate these flights, enabling a market to develop. On the other side of the Atlantic, both the European Space Agency (ESA) and a group of representatives of the European Aviation Safety Agency (EASA) of the European Union (EU) seem to rather regard this activity as aviation, potentially subject to the regulation and certification competences of EASA

IMPACT OF EUROPEAN INTEGRATION ON COMPETITIVENESS OF CZECH REGIONS

Full Text Available Economic integration supports removal of all obstacles (in economy, trade, tax, administration or industrial area and establishment of common rules for market competition. Basic benefit of economic integration is thus occurrence of real or potential competitiveness effects. European integration can influence competitiveness of firm, regions or countries. There are existing agglomeration forces causing space and economic concentration and disperse forces working just opposite way. Both effects are influenced by access to a single market and removal of trade barriers. As a consequence, agglomeration effects are expected to dominate. European Commission established RCI (Regional Competitiveness Index to enable comparison of competitiveness of European regions. Aim of this study is exploration of changes in competitiveness of Czech regions after accession to the European Union as there are no studies analysing regional competitiveness in Czech Republic as a consequence of European integration process via index based approach. Analysis of z statistics of primarily data published by European Commission is used to evaluate theoretical concept of disperse and agglomeration forces. Based on RCI analysis are obvious growing discrepancies with dominant position of Prague and Central Bohemia in comparison with other Czech Regions. Significant differences can be seen in areas of innovations, business sophistication and education. On the opposite, positively can be evaluated lower variability of competitiveness between Czech regions in indicators of infrastructure, institutions and technological readiness. Those indicators could be influenced by European cohesive and regional politics. Decisions on governmental level should follow Europe 2020 strategy and transformation to knowledge based economy.

Full Text Available The growing participation of Spain’s regions, provinces and municipalities in international cooperation has had and continues to have a particular importance in the Mediterranean area, though this has not always been sufficiently acknowledged and supported by the relevant Mediterranean and European authorities. In this cooperation space, two key elements are conjugated: firstly, the process of regional integration in the European space and, secondly, thepromotion of a common area around the Mediterranean. At a time in which foreign policies and classic means of cooperation have shown signs of limitation in terms of the way in which they operate in the region, it seems a suitable moment to reflect on the role that public decentralised cooperation organised by Spain’s local governments could have in the framework of the EU’s new European Policy of Neighbourhood and Association.

European research and development strategy for clean power

Linkohr, R.

2006-01-01

We need more rather than less money for research, energy research in particular, research being an important contributor to progress, in order to achieve peak performance, comply with the quest for knowledge about the structure of the world, or to be able to further improve our quality of life at far less expense of materials and energy. This latter concept is in line with European identity. If we succeed in demonstrating to the world that people can live a better life if they manage their affairs sustainably, we Europeans will have won a new trademark: a sustainable Europe which can be left to future generations. For this purpose Europeans, more than before, must perceive Europe as a space of knowledge. Science policy must be geared to Europe, not just to a national territory. Also, Europe should devote more attention to fundamental research. Some outstanding projects are needed, particularly in energy research, with the participation of industry in order to reduce materials consumption and avoid emissions. Education, too, must be given much attention. In the absence of enthusiastic young scientists, engineers, and skilled workers who know their neighboring countries and their technologies and languages from an early age, European energy policy is bound to remain fragmented.

European Citizenship: Conceptualisation and Contextualisation of a Construct

Directory of Open Access Journals (Sweden)

Hendrik Jan Rebel

2016-05-01

Full Text Available This article is partly based on a preparative article for the European Citizens Conference at the Romanian National University of Political Studies and Administration and some notes for the keynote speech, Bucharest, November 5, 2013. It contains an epistemological (concept formation and methodological (operationalisation approach to the construct of European Citizenship. In the epistemological part occurs a confrontation between the socio-legal conceptual development of the idea of national citizenship (400 BC – 1945 AD and the politico-legal construction of the idea of European Citizenship after 1945 until the present day. The latter gives rise to a bifurcation of the European part (the space and the devalued local part (the place, where national citizenship comes in between, such that we deal with a tripartite citizenship construct. The confrontation between these three forms is shown particularly in EU communication efforts through PR. and PD. which result in a gradual crystallization of the trend in public opinion on the citizenship idea. The epistemological developments should have an effect on the methodology of measurement, for which some indices are constructed as example. These indices form a critical counterpoint against the measurement devices in the Eurobarometers that do not reckon with other relevant disciplines besides social-psychology.

2017-12-01

Space based laser communication is supporting earth observation and science missions with Gbps data download capabilities. Currently the Sentinel 1 and Sentinel 2 spacecrafts from the Copernicus earth observation program of the European Commission are using the Gbps laser communication links developed by Tesat Spacecom to download low latency data products via a commercial geostationary laser relay station- the European Data Relay Service- (EDRS) as a standard data path, in parallel to the conventional radio frequency links. The paper reports on the status of high bandwidth space laser communication as an enabler for small and large space science missions ranging from cube sat applications in low earth orbit to deep space missions. Space based laser communication has left the experimental phase and will support space science missions with unprecedented data rates.

Integration of Physical, Genetic, and Cytogenetic Mapping Data for Cellulose Synthase (CesA Genes in Flax (Linum usitatissimum L.

Full Text Available Flax, Linum usitatissimum L., is a valuable multi-purpose plant, and currently, its genome is being extensively investigated. Nevertheless, mapping of genes in flax genome is still remaining a challenging task. The cellulose synthase (CesA multigene family involving in the process of cellulose synthesis is especially important for metabolism of this fiber crop. For the first time, fluorescent in situ hybridization (FISH-based chromosomal localization of the CesA conserved fragment (KF011584.1, 5S, and 26S rRNA genes was performed in landrace, oilseed, and fiber varieties of L. usitatissimum. Intraspecific polymorphism in chromosomal distribution of KF011584.1 and 5S DNA loci was revealed, and the generalized chromosome ideogram was constructed. Using BLAST analysis, available data on physical/genetic mapping and also whole-genome sequencing of flax, localization of KF011584.1, 45S, and 5S rRNA sequences on genomic scaffolds, and their anchoring to the genetic map were conducted. The alignment of the results of FISH and BLAST analyses indicated that KF011584.1 fragment revealed on chromosome 3 could be anchored to linkage group (LG 11. The common LG for 45S and 5S rDNA was not found probably due to the polymorphic localization of 5S rDNA on chromosome 1. Our findings indicate the complexity of integration of physical, genetic, and cytogenetic mapping data for multicopy gene families in plants. Nevertheless, the obtained results can be useful for future progress in constructing of integrated physical/genetic/cytological maps in L. usitatissimum which are essential for flax breeding.

Correlation of Cesarean rates to maternal and infant mortality rates: an ecologic study of official international data Correlación de la tasa de cesáreas con las tasas de mortalidad materna e infantil: estudio ecológico basado en datos oficiales internacionales

Full Text Available OBJECTIVE: To correlate international official data on Cesarean delivery rates to infant and maternal mortality rates and low weight-at-birth rates; and to test the hypothesis that Cesarean rates greater than 15% correlate to higher maternal and infant mortality rates. METHODS: Analyses were based on the most recent official data (2000-2009 available for 193 countries. Exponential models were compared to quadratic models to regress infant mortality rates, neonatal mortality rates, maternal mortality rates, and low weight-at-birth rates to Cesarean rates. Separate regressions were performed for countries with Cesarean rates greater than 15%. RESULTS: In countries with Cesarean rates less than 15%, higher Cesarean rates were associated to lower infant, neonatal, and maternal mortality rates, and to lower rates of low weightat-birth. In countries with Cesarean rates greater than 15%, Cesarean rates were not significantly associated with infant or maternal mortality rates. CONCLUSIONS: There is an inverse exponential relation between countries' rates of Cesarean deliveries and infant or maternal mortality rates. Very low Cesarean rates (less than 15% are associated with poorer maternal and child outcomes. Cesarean rates greater than 15% were neither correlated to higher maternal nor child mortality, nor to low weight-at-birth.OBJETIVO: Correlacionar los datos oficiales internacionales sobre las tasas de parto por cesárea con las tasas de mortalidad materna e infantil y con la tasa de bajo peso al nacer, y someter a prueba la hipótesis que sostiene que una tasa de cesáreas mayor de 15% se correlaciona con tasas de mortalidad materna e infantil más elevadas. MÉTODOS: Los análisis se basaron en los datos oficiales más recientes disponibles (2000-2009 de 193 países. Se compararon modelos exponenciales con modelos cuadráticos para hacer un análisis de regresión de las tasas de mortalidad infantil, neonatal y materna, así como de las tasas de

The analysis of food products retailing in European Union

Full Text Available Author is analyzing a share of food products in the structural profile of retail trade in European Union by presenting areas of retailing in which food, beverages, and tobacco products are predominant. The main task of retailing is to overcome gaps in time and space between production and consumption, in order to meet the needs of consumers. This main task of retailing becomes more difficult considering the fact that the European Union consists of demanding consumers that expect all products, especially food, to be served to them at the most accessible places, in most suitable time, and with prices that coincide with the worth of products. In the structure of retail trade of the European Union, food products can be found in sector of non-specialised in-store retailing (hypermarkets, supermarkets, Cash&Carry stores as well as in sector of specialised in-store food retailing (butcher shops, bakeries, fish markets, etc.. Restructure of retailing, internationalization, and concentration of total retail trade network are only some of the basic trends in contemporary retail sale of food products in the European Union, that are being explored in this text.

Full Text Available The production function explains the mechanism through which inputs are changed into outputs and the partial efficiency of labour and capital. It also allows for understanding the elasticity of substitution, which measures the percentage change in factor proportions due to a percentage change in the marginal rate of technical substitution. In this research we have used aggregate production functions of Cobb-Douglas type in different time-series and cross-section analysis of Romania’s economic growth from the standpoint of the intensity of using capital and labour factors, as determinant elements for the level of production and GDP. We have also applied the two factor Constant Elasticity of Substitution (CES production function, which is considered to be the generalised form of the Cobb-Douglas function. Using the available statistical data regarding Romania’s economy in the 1990-2005 period, we have performed time-series and cross-section analysis based on the aggregated production functions at the national level.

A Stronger EU in Cosmos: Embracing the Concept of Space Security

Directory of Open Access Journals (Sweden)

Peter PINDJÁK

2016-09-01

Full Text Available The recently unveiled EU Global Strategy for Foreign and Security Policy presents bold and ambitious plans in several increasingly important domains for Europe, including outer space. The EU has committed itself to securing an autonomous access to space, providing security for its space-based assets, and promoting the adoption of a voluntary code of conduct in space. With the evolving dynamics in astropolitics, space security has become an ever more important aspect of space activities. Clearly, the EU has a vested interest in space security, whereas space-enabled services form an important part of European economy and contribute to effective implementation of its energy policy, migration, border control as well as domestic and international crisis management. Since the EU is currently in the process of drafting a European Space Strategy, it should seize the opportunity to take stock of its existing space programs and lay out a promising way forward. Besides reinforcing the existing Copernicus and Galileo programs and further developing the Governmental Satellite Communications (GOVSATCOM project, the EU should make a significant investment in space security, particularly through boosting its Space Surveillance and Tracking (SST capabilities and actively working on the international fora to promote a responsible behavior in outer space that could be eventually transformed into a voluntary international code of conduct. Through a comprehensive space policy and by reinforcing its autonomy in outer space, the EU will not only strengthen its foreign and security policy, but also reconfirm its relevant role in global affairs.

The European Hubble Archive (hereafter eHST), hosted at ESA's European Space Astronomy Centre, has been released for public use in October 2015. The eHST is now fully integrated with the other ESA science archives to ensure long-term preservation of the Hubble data, consisting of more than 1 million observations from 10 different scientific instruments. The public HST data, the Hubble Legacy Archive, and the high-level science data products are now all available to scientists through a single, carefully designed and user friendly web interface. In this talk, I will show how the the eHST can help boost archival research, including how to search on sources in the field of view thanks to precise footprints projected onto the sky, how to obtain enhanced previews of imaging data and interactive spectral plots, and how to directly link observations with already published papers. To maximise the scientific exploitation of Hubble's data, the eHST offers connectivity to virtual observatory tools, easily integrates with the recently released Hubble Source Catalog, and is fully accessible through ESA's archives multi-mission interface.

Territory and Sustainable Tourism Development: a Space-Time Analysis on European Regions

Directory of Open Access Journals (Sweden)

João Romão

2017-07-01

Full Text Available In the long run, tourism competitiveness depends on the sustainable use of territorial assets: the differentiation of destinations depends on the integration of cultural and natural resources into the tourism supply, but also on their preservation over time. The link between competitiveness and sustainability is the staring point for our analysis of the relationships between regional tourism competitiveness, the dynamics of tourism demand and investment and the existence of natural resources and cultural assets in European regions, by using advanced spatial econometric techniques. Despite the close relationship between tourism activities and the characteristics of the territory, the application of methods of spatial analysis methods in tourism studies is still scarce and the results of this work clearly show their potential for this field of research. Among the main findings of this paper, it was observed that natural resources do not have the expected positive impacts on regional tourism competitiveness and that European regions with more abundant natural resources are often developing unsustainable forms of mass tourism, with low value added and scarce benefits for the host communities. The existence of spatial correlation effects suggests that positive spillovers arising from tourism dynamics in neighbourhood regions prevail over potential negative effects related to the competition between destinations. Policy and managerial implications of these results are discussed and further research questions are suggested.

The THESEUS project (Towards Human Exploration of Space: a European Strategy), initiated within the seventh Framework Programme by the European Commission, aimed at providing a cross-cutting, life-science-based roadmap for Europe's strategy towards human exploration of long space missions, and its relevance to applications on Earth. This topic was investigated by experts in the field, in the framework of the THESEUS project whose aim was to develop an integrated life sciences research roadmap regarding human space exploration. In particular, decades of research have shown that altered gravity impairs neurological responses at large, such as perception, sleep, motor control, and cognitive factors. International experts established a list of key issues that should be addressed in that context and provided several recommendations such as a maximal exploitation of currently available resources on Earth and in space.

Hoffimann, Elaine; Barros, Henrique; Ribeiro, Ana Isabel

2017-08-15

Background : The provision of green spaces is an important health promotion strategy to encourage physical activity and to improve population health. Green space provision has to be based on the principle of equity. This study investigated the presence of socioeconomic inequalities in geographic accessibility and quality of green spaces across Porto neighbourhoods (Portugal). Methods : Accessibility was evaluated using a Geographic Information System and all the green spaces were audited using the Public Open Space Tool. Kendall's tau-b correlation coefficients and ordinal regression were used to test whether socioeconomic differences in green space quality and accessibility were statistically significant. Results : Although the majority of the neighbourhoods had an accessible green space, mean distance to green space increased with neighbourhood deprivation. Additionally, green spaces in the more deprived neighbourhoods presented significantly more safety concerns, signs of damage, lack of equipment to engage in active leisure activities, and had significantly less amenities such as seating, toilets, cafés, etc. Conclusions : Residents from low socioeconomic positions seem to suffer from a double jeopardy; they lack both individual and community resources. Our results have important planning implications and might contribute to understanding why deprived communities have lower physical activity levels and poorer health.

Full Text Available The unprecedented development of criminality at the social and economical levels, the tendency toglobalize some categories of crimes, of maximum gravity, as terrorism, armament traffic, drug traffic orhuman traffic, have determined the world states to undertake specific measures to prevent, combat and finallyreduce it. The first and most important measure taken by the Europe’s Council, regarding the intensificationof judicial cooperation in criminal matters was the adoption of the European Convention on extradition, inParis on 13 December 1957, completed by the two Additional Protocols in Strasbourg, on 15 October 1975and 17 March 1978. In this context, the release of the Council’s Framework Decision on 13 June 2002 on theEuropean arrest warrant and the procedures of delivery among the member states (2002/584/JAI representeda natural decision, with the purpose of contributing at ensuring a free, secure and just European space. TheEuropean arrest warrant is a judicial decision through which a competent judicial authority of a EuropeanUnion member state solicits the arrest and delivery by another member state, in order to proceed to theprosecution, trial or execution of a penalty or safety measure that is privative of freedom.

Cubature on Wiener space (Lyons and Victoir in Proc. R. Soc. Lond. A 460(2041):169–198, 2004) provides a powerful alternative to Monte Carlo simulation for the integration of certain functionals on Wiener space. More specifically, and in the language of mathematical finance, cubature allows for fast computation of European option prices in generic diffusion models.We give a random walk interpretation of cubature and similar (e.g. the Ninomiya–Victoir) weak approximation schemes. By using rough path analysis, we are able to establish weak convergence for general path-dependent option prices.

The unknown story of the European carbon market: an archaeology of the electrical sector

International Nuclear Information System (INIS)

Cartel, Melodie; Aggeri, Franck; Caneill, Jean-Yves

2017-01-01

In economic literature, the creation of the European carbon market is presented as a major institutional innovation that can be viewed as a direct application of economic theory. In this article, we propose another version of how the European carbon market came about that emphasizes the active role played by companies. For a period of three years, these companies designed and tested a prototype carbon market, while being observed by European experts. Drawing on archive documents, we analyze this experimentation process and examine in detail its influence on the European carbon market. We then discuss the role of companies in the processes of institutional innovation, a process that generally remains invisible. Finally it is explained how such experiments, conducted in protected spaces, can facilitate the design and testing of new concepts

1997-03-01

Single event effects are an important hazard to spacecraft and payloads. The advances in component technology, with shrinking dimensions and increasing complexity will give even more importance to single event effects in the future. The ground test facilities are complex and expensive and the complexities of installing a facility are compounded by the requirement that maximum control is to be exercised by users largely unfamiliar with accelerator technology. The PIF and the HIF are the result of experience gained in the field of single event effects testing and represent a unique collaboration between space technology and accelerator experts. Both facilities form an essential part of the European infrastructure supporting space projects. (J.P.N.)

European communion

DEFF Research Database (Denmark)

Manners, Ian James

2013-01-01

Political theory of European union, through an engagement between political concepts and theoretical understandings, provides a means of identifying the EU as a political object. It is argued that understanding the projects, processes and products of European union, based on ‘sharing’ or ‘communion......’, provides a better means of perceiving the EU as a political object rather than terms such as ‘integration’ or ‘co-operation’. The concept of ‘European communion’ is defined as the ‘subjective sharing of relationships’, understood as the extent to which individuals or groups believe themselves to be sharing...... relations (or not), and the consequences of these beliefs for European political projects, processes and products. By exploring European communion through an engagement with contemporary political theory, using very brief illustrations from the Treaty of Lisbon, the article also suggests that European...

Full Text Available The article analyses the Europeanization policy of the European Union towards the Eastern Partnership participant countries. Suffering from the lack of clear strategy and ultimate goal in the European Neighbourhood Policy the European Union enhances external democratization and its governance in post soviet states without immediate Union's membership perspective. Underestimation of common neighbourhood geopolitical duality in the context of growing rivalry between European (EU and Eurasian (Custom Union/Eurasian Economic Union integration gravitation centers presents the Eastern partners of the EU with a fierce dilemma of externally forced immediate geopolitical and civilizational choice while not all of them are well prepared to such a choice. The mutual Europeanization trap here to be studied both for the EU and its Eastern partners (involving Russia is a deficiency of regulating cooperation mechanism in the situation of European and Eurasian free trades zones overlapping. Vilnius Summit 2013 results test the "European aspirations" of the New Independent States and upset the ongoing process of the European Neighbourhood Policy in the context of growing economic interdependence in Wider Europe. Besides, the Ukrainian crisis escalation during 2014 as a new seat of tension provokes unbalance of the whole European security system and creates new dividing lines in Europe from Vancouver to Vladivostok.

Privacy protection on the internet: The European model

2017-01-01

Full Text Available The Internet has a huge impact on all areas of social activity. Everyday life, social interaction and economics are directed to new information and communication technologies. A positive aspect of the new technology is reflected in the fact that it has created a virtual space that has led to the elimination of the various barriers, which has enabled interaction and information exchange across the world. Inclusion in the virtual social network provides connectivity for communicators who are looking for space that allows them freedom of expression and connect them with new ' friends'. Because of the feeling of complete freedom and the absence of censorship on the network communicators leave many personal details and photos, without thinking about the possible abuses of privacy. Recording of the different incidents on the network has resulted in the need to take precaution measures, in order to protect the users and the rule of law, given that freedom on the network is only possible with the existence of an adequate system of safety and security. In this paper we deal with the problem of the protection of personal data of users of virtual social networks against malicious activity and abuse, with special reference to the activities of the European Union in an effort to regulate this area. The European Commission has concentrated on finding the best solutions to protect the user's virtual space for more than two decades, starting from 1995 until a directive on security of networks and information systems, which was adopted in the first half of 2016.

2013-01-01

This paper provides an overview of the system and subsystem configuration of the MPCV European Service Module (ESM) at Preliminary Design Review (PDR) stage as well as its perspectives of utilisation within the global space exploration endeavour. The MPCV ESM is a cylindrical module with a diameter of 4500 mm and a total length – main engine excluded – of 2700 mm. It is fitted with four solar array wings with a span of 18.8 m. Its dry mass is 3.5 metric tons and it can carry 8.6 tons of propellant. The main functions of the European Service Module are to bring the structural continuity between the launcher and the crew module, to provide propulsion to the MPCV, to ensure its thermal control as well as electrical power and to store water, oxygen and nitrogen for the mission. The current agreement foresees the development and production by Europe of one flight model, with an option for a second one. This module will be assembled in Europe and delivered to NASA in 2016. It will be used for a flight of the MPCV Orion in December 2017.

Various technical and legal aspects of nuclear power sources in outer space

International Nuclear Information System (INIS)

Boeck, H.; Summerer, L.

2001-12-01

Since the very first days of space exploration, nuclear power was considered as an alternative to solar cells for the generation of energy in space. Especially for larger exploration missions beyond Mars, nuclear power sources (NPS) are almost unavoidable. NPS are developed, produced and flown on a continuous basis since almost 40 years by the USA and the Soviet Union, now Russia. While the technological capabilities certainly exist within Europe, Europe has not developed space nuclear power sources. This work is structured in four parts, enlightening this subject from different viewpoints on the European level. In a first chapter, European centres researching in the broader field of this technology are listed. A second chapter deals with the properties and hazards connected with plutonium, the element used in Radioisotope Thermal Generators (RTG). Recent technological developments in the field of RTG are reviewed in chapter 4, while chapter 3 deals with the international legal implications of the use of nuclear power sources in outer space.

Full Text Available The problem of the North-Western Moldavia (named later on, by the Austrian occupants, Bukovina emerged within the European geopolitical space in 1775, when the territory has been annexed by the Habsburg Empire. However, before that moment, the Northern part of the future Bukovina (Şipeniţ district was disputed by Poland and Moldavia Yet, the Polish-Moldavian border was clearly established, including the Northern part of Bucovina (wanted by Poland within the Moldavian Principality. The Austrian emperor and administration used a few motivations for the annexation of the North-Western Moldavia: 1. the imposition of a cordon against the plague („which burned down long time before in Moldavia”; 2. „the need” to annex „a strip” (in reality, two big districts were annexed from the territory of Moldavia for the construction of a road linking Transylvania with Galicia; 3. the historical rights of the Pocuţia (i.e., Galicia, which have come in possession of Austria, on the North of Moldavia (Şipeniţ County. Some of the real reasons of occupation were: 1. „insatiable hunger for new territorial acquisitions; lust for the expansion of the Empire and seizing new territories bringing profit; 2. to compensate for the loss of another territory – Oltenia – in this case, with the North-Western Moldavia; 3. a desire to have a strategic area to be pursued in a subsequent expansion in Moldavia and Wallachia, respectively in the Danube region and in the Eastern Balkans. As in June 1940, the Soviet authorities have linked the issue of Bessarabia with the issue of Bukovina, I believe that the problem of Transnistria (Moldavia should be viewed in connection with the issue of ethnic Romanian Community territory of Northern Bukovina (now in Cernăuţi region. A solution for the problem of the Romanian community in Northern Bukovina is possible by the passage of municipalities inhabited by Romanians from Northern Bukovina to Republic of Moldavia, in

STEAM is an educational approach to learning that uses Science, Technology, Engineering, the Arts and Mathematics as access points for guiding student inquiry, dialogue, and critical thinking. The end results are students who take thoughtful risks, engage in experiential learning, persist in problem-solving, embrace collaboration, and work through the creative process. The Outer Space is a window to the past and the future of our travel around the history of the Universe and can be used as a educational tool in primary and secondary education. This paper talks about the integration of the resources of European Space Agency, Space Awareness, Nuclio, Scientix and Schoolnet as motivation to integrate STEAM methodology in secondary education.

Hultqvist, B.; Hagfors, T.

1983-01-01

This book constitutes the proceedings of the Nobel Symposium No. 54 on High Latitude Magnetospheric/Ionospheric Plasma Physics. The main purpose of the symposium was to prepare for the European research effort in space plasma physics in the mid-1980's, in which two major constituents are the European Incoherent Scatter Association (EISCAT) facilities and the Swedish satellite Viking. The physics of the high-latitude ionosphere and how this part of near space is affected by the properties of the solar wind and the interplanetary magnetic field are explored. A detailed discussion is provided on high-latitude magnetospheric physics at altitudes of 1-2 earth radii, the main focus of the Viking project. Specific topics considered include the role of the auroral ionosphere in magnetospheric substorms, the low altitude cleft, ionospheric modification and stimulated emissions, plasma physics on auroral field lines, solar wind-magnetosphere energy coupling, cold plasma distribution above a few thousand kilometers at high latitudes, hot electrons in and above the auroral ionosphere, the correlation of auroral kilometric radiation with visual auroras and with Birkeland currents, electrostatic waves in the topside ionosphere, solitary waves and double layers, and an Alfven wave model of auroral arcs

Multicultural Ground Teams in Space Programs

Science.gov (United States)

Maier, M.

2012-01-01

In the early years of space flight only two countries had access to space. In the last twenty years, there have been major changes in how we conduct space business. With the fall of the iron curtain and the growing of the European Union, more and more players were able to join the space business and space science. By end of the last century, numerous countries, agencies and companies earned the right to be equal partners in space projects. This paper investigates the impact of multicultural teams in the space arena. Fortunately, in manned spaceflight, especially for long duration missions, there are several studies and simulations reporting on multicultural team impact. These data have not been as well explored on the team interactions within the ground crews. The focus of this paper are the teams working on the ISS project. Hypotheses will be drawn from the results of space crew research to determine parallels and differences for this vital segment of success in space missions. The key source of the data will be drawn from structured interviews with managers and other ground crews on the ISS project.

ECLIPSE, an Emerging Standardized Modular, Secure and Affordable Software Toolset in Support of Product Assurance, Quality Assurance and Project Management for the Entire European Space Industry (from Innovative SMEs to Primes and Institutions)

Bennetti, Andrea; Ansari, Salim; Dewhirst, Tori; Catanese, Giuseppe

2010-08-01

The development of satellites and ground systems (and the technologies that support them) is complex and demands a great deal of rigor in the management of both the information it relies upon and the information it generates via the performance of well established processes. To this extent for the past fifteen years Sapienza Consulting has been supporting the European Space Agency (ESA) in the management of this information and provided ESA with ECSS (European Cooperation for Space Standardization) Standards based Project Management (PM), Product Assurance (PA) and Quality Assurance (QA) software applications. In 2009 Sapienza recognised the need to modernize, standardizing and integrate its core ECSS-based software tools into a single yet modularised suite of applications named ECLIPSE aimed at: • Fulfilling a wider range of historical and emerging requirements, • Providing a better experience for users, • Increasing the value of the information it collects and manages • Lowering the cost of ownership and operation • Increasing collaboration within and between space sector organizations • Aiding in the performance of several PM, PA, QA, and configuration management tasks in adherence to ECSS standards. In this paper, Sapienza will first present the toolset, and a rationale for its development, describing and justifying its architecture, and basic modules composition. Having defined the toolset architecture, this paper will address the current status of the individual applications. A compliance assessment will be presented for each module in the toolset with respect to the ECSS standard it addresses. Lastly experience from early industry and Institutional users will be presented.

Sea Surface Temperature for Climate Applications: A New Dataset from the European Space Agency Climate Change Initiative

Science.gov (United States)

Merchant, C. J.; Hulley, G. C.

2013-12-01

There are many datasets describing the evolution of global sea surface temperature (SST) over recent decades -- so why make another one? Answer: to provide observations of SST that have particular qualities relevant to climate applications: independence, accuracy and stability. This has been done within the European Space Agency (ESA) Climate Change Initative (CCI) project on SST. Independence refers to the fact that the new SST CCI dataset is not derived from or tuned to in situ observations. This matters for climate because the in situ observing network used to assess marine climate change (1) was not designed to monitor small changes over decadal timescales, and (2) has evolved significantly in its technology and mix of types of observation, even during the past 40 years. The potential for significant artefacts in our picture of global ocean surface warming is clear. Only by having an independent record can we confirm (or refute) that the work done to remove biases/trend artefacts in in-situ datasets has been successful. Accuracy is the degree to which SSTs are unbiased. For climate applications, a common accuracy target is 0.1 K for all regions of the ocean. Stability is the degree to which the bias, if any, in a dataset is constant over time. Long-term instability introduces trend artefacts. To observe trends of the magnitude of 'global warming', SST datasets need to be stable to <5 mK/year. The SST CCI project has produced a satellite-based dataset that addresses these characteristics relevant to climate applications. Satellite radiances (brightness temperatures) have been harmonised exploiting periods of overlapping observations between sensors. Less well-characterised sensors have had their calibration tuned to that of better characterised sensors (at radiance level). Non-conventional retrieval methods (optimal estimation) have been employed to reduce regional biases to the 0.1 K level, a target violated in most satellite SST datasets. Models for

Population-Area Relationship for Medieval European Cities.

Rudolf Cesaretti

Full Text Available Medieval European urbanization presents a line of continuity between earlier cities and modern European urban systems. Yet, many of the spatial, political and economic features of medieval European cities were particular to the Middle Ages, and subsequently changed over the Early Modern Period and Industrial Revolution. There is a long tradition of demographic studies estimating the population sizes of medieval European cities, and comparative analyses of these data have shed much light on the long-term evolution of urban systems. However, the next step-to systematically relate the population size of these cities to their spatial and socioeconomic characteristics-has seldom been taken. This raises a series of interesting questions, as both modern and ancient cities have been observed to obey area-population relationships predicted by settlement scaling theory. To address these questions, we analyze a new dataset for the settled area and population of 173 European cities from the early fourteenth century to determine the relationship between population and settled area. To interpret this data, we develop two related models that lead to differing predictions regarding the quantitative form of the population-area relationship, depending on the level of social mixing present in these cities. Our empirical estimates of model parameters show a strong densification of cities with city population size, consistent with patterns in contemporary cities. Although social life in medieval Europe was orchestrated by hierarchical institutions (e.g., guilds, church, municipal organizations, our results show no statistically significant influence of these institutions on agglomeration effects. The similarities between the empirical patterns of settlement relating area to population observed here support the hypothesis that cities throughout history share common principles of organization that self-consistently relate their socioeconomic networks to structured

A Cooperative program between the French Centre National d'Etudes Spatiales (CNES) and the Commissariat a l'Engergie Atomique (CEA) was initiated in 1983, to investigate the possible development of 20 to 200 kWe space nuclear power systems to be launched by the next version of the European launcher, Ariane V. After completion in 1986 of preliminary conceptual studies of a reference 200 kWe turboelectric power system, an additional 3 year study phase was decided, with the double objective of assessing the potential advantage of nuclear power systems versus solar photovoltaic or dynamic systems in the 20 kWe power range, and comparing various reactor candidate technologies and systems options for 20 kWe space nuclear power systems, likely to meet the projected energy needs of future European space missions. The results of this study are discussed by the authors

The CAS-NAS forum for new leaders in space science

Science.gov (United States)

Smith, David H.

The space science community is thoroughly international, with numerous nations now capable of launching scientific payloads into space either independently or in concert with others. As such, it is important for national space-science advisory groups to engage with like-minded groups in other spacefaring nations. The Space Studies Board of the US National Academy of Sciences' (NAS') National Research Council has provided scientific and technical advice to NASA for more than 50 years. Over this period, the Board has developed important multilateral and bilateral partnerships with space scientists around the world. The primary multilateral partner is COSPAR, for which the Board serves as the US national committee. The Board's primary bilateral relationship is with the European Science Foundation’s European Space Science Committee. Burgeoning Chinese space activities have resulted in several attempts in the past decade to open a dialogue between the Board and space scientists in China. On each occasion, the external political environment was not conducive to success. The most recent efforts to engage the Chinese space researchers began in 2011 and have proved particularly successful. Although NASA is currently prohibited from engaging in bilateral activities with China, the Board has established a fruitful dialogue with its counterpart in the Chinese Academy of Sciences (CAS). A joint NAS-CAS activity, the Forum for New Leaders in Space Science, has been established to provide opportunities for a highly select group of young space scientists from China and the United States to discuss their research activities in an intimate and collegial environment at meetings to be held in both nations. The presentation will describe the current state of US-China space relations, discuss the goals of the joint NAS-CAS undertaking and report on the activities at the May, 2014, Forum in Beijing and the planning for the November, 2014, Forum in Irvine, California.

Design course in space astronomy

International Nuclear Information System (INIS)

Dean, A J; Perez-Fournon, I

2003-01-01

The aim of this course is to provide direct experience of collaboration with other European astronomy/space science students and to gain an insight into the establishment of ESA space science programmes. The first half of the course takes place in Southampton. The Southampton students work as a team to track a past ESA space science mission from initial conception through to final realization and operations. This is achieved through the study of the high quality documentation available in the form of ESA reports. Each student has well defined responsibilities within the team. The second half of the course takes place in Tenerife, at the University of La Laguna. Again the students are expected to complete a team study of a space science mission. This time, however, there are important differences: the study teams are now international, approximately half Southampton and half University of La Laguna students; and this time they are expected to design a completely new space astronomy mission with clearly specified scientific objectives and operational constraints

SWIFF: Space weather integrated forecasting framework

Directory of Open Access Journals (Sweden)

Frederiksen Jacob Trier

2013-02-01

Full Text Available SWIFF is a project funded by the Seventh Framework Programme of the European Commission to study the mathematical-physics models that form the basis for space weather forecasting. The phenomena of space weather span a tremendous scale of densities and temperature with scales ranging 10 orders of magnitude in space and time. Additionally even in local regions there are concurrent processes developing at the electron, ion and global scales strongly interacting with each other. The fundamental challenge in modelling space weather is the need to address multiple physics and multiple scales. Here we present our approach to take existing expertise in fluid and kinetic models to produce an integrated mathematical approach and software infrastructure that allows fluid and kinetic processes to be modelled together. SWIFF aims also at using this new infrastructure to model specific coupled processes at the Solar Corona, in the interplanetary space and in the interaction at the Earth magnetosphere.

LABOUR TAXATION IN THE EUROPEAN UNION

Directory of Open Access Journals (Sweden)

Sabau-Popa Liviu Mihai

2011-07-01

Full Text Available This article proposes an analysis, which we consider extremely useful in the current economic context, of the evolution of labour income fiscality, more precisely, the effect of the public debt growth on the tax wedge for the labour income. The share of fiscal revenues from direct taxes, indirect taxes and social contributions is relatively close in the old member states of the European Union in comparison with the new member states, which register a lower level of income from direct taxes. The low level of income from direct taxes is compensated by more significant shares of the social contributions or indirect taxes. The main motivations of cross-border migration are: a successful career in a multinational corporation, high variations of the tax rate, of the salary income between states and, last but not least, the level of the net salary. To this day, there are no plans to harmonize across the European Union the legislation regarding the taxes wages and the social security contributions. Still, the European Union had in view the coordination of the national tax systems to make sure that the employees and the employers do not pay several times the social contributions in their movement across the community space. Despite the fact that some states tax the labour income at a low level, the labour fiscality remains high in the European Union in comparison with other industrialized economies, probably also due to the fact that the majority of the member states have social market economies. The increase of the fiscality level for the labour income determines the decrease of the employment rate and the raise of the unemployement rate. The solution to guarantee a higher employment rate, which is a target of the European Union Strategy Europe 2020 could be the relaxation of the labour income fiscality by transferring the tax wedge on the labour income towards property or energy taxation.

Full Text Available The multiplication of objects, actors and underlying rationales of heritage development, or patrimonialisation, is increasingly blurring the strength and meaning of our relationship with the past. The aim of this article is to reflect on the processes involved in the emergence of new heritage objects and on the consequences of these developments. The article is based on a comparative analysis of two symmetric objects, both of which have been the subject of heritage development processes: the Chauvet cave and the Millau viaduct in Southern France. By showing that each object is projected in the spatial or temporal dimension from which it was a priori excluded at the time of its discovery, the analysis demonstrates the necessity of integrating a heritage approach to our understanding of territorial dynamics. The analysis suggests that the interplay of territorialisation and heritage development processes represents a reconstruction of a controlled time-space, a prerequisite for addressing a recurring problem in our society, that of its sustainability.La multiplication des objets, des acteurs et des logiques de la patrimonialisation génère un brouillage de plus en plus important sur la force et le sens de nos rapports au passé. Dans ce contexte, cet article se propose de réfléchir aux processus d’émergence de nouveaux objets patrimoniaux et aux conséquences de ces mobilisations. Il s’appuie sur l’analyse comparée de deux objets symétriques et tous deux patrimonialisés : la grotte Chauvet et le viaduc de Millau. En montrant que chaque objet est projeté dans la dimension spatiale ou temporelle dont il se trouve a priori exclu lors de son invention, l’analyse rappelle la nécessité d’intégrer une approche patrimoniale à notre lecture des dynamiques territoriales. Elle propose alors l’idée que ces mouvements croisés représentent une reconstruction d’un espace-temps maitrisé, nécessaire pour répondre au probl

Full Text Available Objective The Lisbon Strategy set a new goal for the EU economy: the transition to a knowledge based economy, competitive and sustainable at macro and regional levels, by creating the European Research Area – a geographic area without frontiers for researches, where scientific resources are better managed to create more jobs and improve Europe's competitiveness. That means an interaction between specific and multidisciplinary research network. Approach However, general research methodology sustains the importance of static and revolutionary specific criteria of Scientific Research Programs but also reveals the natural process of multidisciplinary researches. In this context, the European Union could be regarded as a specific and multidisciplinary research area, as a network of flows, connections, relationships, interdependencies, and interferences between natural - experimental and social-humanistic research spheres (economics, management, sociology and complex systems ecology. Prior Work: In this respect some researchers suggested that both natural and social systems could be considered as multidisciplinary complex adaptive systems consisting of specific cluster network connections ( in the form of biotic and abiotic nodes, respectively, the competitive and regional poles with the ability to continuous self-organizing, learning and regenerating process especially in crisis situations. Implications and Value Paper Utility The present paper might be useful to illustrate the contribution of technical-economic and socio-ecological researches to increasing the sustainability framework of European Research Area by considering the transition from the R&D approach (development through research process to the L&D approach (development through learning process.

The European standard on planetary protection requirements.

Debus, André

2006-01-01

Since the beginning of solar system exploration, numerous spacecrafts have been sent towards others worlds, and one of the main goals of such missions is the search for extraterrestrial forms of life. It is known that, under certain conditions, some terrestrial entities are able to survive during cruises in space and that they may contaminate other planets (forward contamination). At another level, possible extraterrestrial life forms are unknown and their ability to contaminate the Earth's biosphere (back contamination) in the frame of sample return missions cannot be excluded. Article IX of the Outer Space Treaty (London/Washington, January 27, 1967) requires the preservation of planets and the Earth from contamination. All nations taking part in this Treaty must prevent forward and back contamination during missions exploring our solar system. Consequently, the United Nations (UN-COPUOS) has delegated COSPAR (Committee of Space Research) to take charge of planetary protection and, at present, all space-faring nations must comply with COSPAR policy and consequently with COSPAR planetary protection recommendations. Starting from these recommendations and the "CNES Planetary Protection Standard" document, a working group has been set up in the framework of the "European Cooperation for Space Standardization" (ECSS) to establish the main specifications for preventing cross-contamination between target bodies within the solar system and the Earth-moon system.

2002-02-01

In 2004, the European COLUMBUS Module is to be attached to the International Space Station. On the way to the successful planning, deployment and operation of the module, computer generated and animated models are being used to optimize performance. Under contract of the German Space Agency DLR, it has become IRF's task to provide a Projective Virtual Reality System to provide a virtual world built after the planned layout of the COLUMBUS module let astronauts and experimentators practice operational procedures and the handling of experiments. The key features of the system currently being realized comprise the possibility for distributed multi-user access to the virtual lab and the visualization of real-world experiment data. Through the capabilities to share the virtual world, cooperative operations can be practiced easily, but also trainers and trainees can work together more effectively sharing the virtual environment. The capability to visualize real-world data will be used to introduce measured data of experiments into the virtual world online in order to realistically interact with the science-reference model hardware: The user's actions in the virtual world are translated into corresponding changes of the inputs of the science reference model hardware; the measured data is than in turn fed back into the virtual world. During the operation of COLUMBUS, the capabilities for distributed access and the capabilities to visualize measured data through the use of metaphors and augmentations of the virtual world may be used to provide virtual access to the COLUMBUS module, e.g. via Internet. Currently, finishing touches are being put to the system. In November 2001 the virtual world shall be operational, so that besides the design and the key ideas, first experimental results can be presented.

Over the next four years the Europlanet 2020 Research Infrastructure will set up an entirely new European Planetary Space Weather service (PSWS). Europlanet RI is a part of of Horizon 2020 (EPN2020-RI, http://www.europlanet-2020-ri.eu). The Virtual Access Service, WP5 VA1 "Planetary Space Weather Services" will extend the concepts of space weather and space situational awareness to other planets in our Solar System and in particular to spacecraft that voyage through it. VA1 will make five entirely new 'toolkits' accessible to the research community and to industrial partners planning for space missions: a general planetary space weather toolkit, as well as three toolkits dedicated to the following key planetary environments: Mars (in support ExoMars), comets (building on the expected success of the ESA Rosetta mission), and outer planets (in preparation for the ESA JUICE mission to be launched in 2022). This will give the European planetary science community new methods, interfaces, functionalities and/or plugins dedicated to planetary space weather in the tools and models available within the partner institutes. It will also create a novel event-diary toolkit aiming at predicting and detecting planetary events like meteor showers and impacts. A variety of tools (in the form of web applications, standalone software, or numerical models in various degrees of implementation) are available for tracing propagation of planetary and/or solar events through the Solar System and modelling the response of the planetary environment (surfaces, atmospheres, ionospheres, and magnetospheres) to those events. But these tools were not originally designed for planetary event prediction and space weather applications. So WP10 JRA4 "Planetary Space Weather Services" (PSWS) will provide the additional research and tailoring required to apply them for these purposes. The overall objectives of this Joint Research Aactivities will be to review, test, improve and adapt methods and tools

Las tasas de descomposición y liberación de nutrimentos fueron bien descritas por un modelo exponencial doble. Se observó alta relación entre las tasas de pérdida de biomasa y liberación de N de las tres especies. Las tasas de liberación de nutrimentos fueron K > Mg > P > N > Ca. Después de una semana de incubación cerca del 90% del K fue liberado mientras que el Ca tendió a la acumulación. Las raíces de poró fueron las de más rápida descomposición y liberación de nutrimentos, excepto de K. El poró sería la especie de sombra adecuada para sistemas de producción que requieran rápida recirculación de nutrimentos. El laurel exhibió tasas lentas de descomposición y liberación de nutrimentos.

The Impact of Space Commercialization on Space Agencies: the Case of NASA

Science.gov (United States)

Zervos, Vasilis

2002-01-01

The purpose of this paper is to examine the hypothesis that commercialisation of space results in inefficient contracting policies by the space agencies, using the US NASA as a case study. Though commercialisation is seen by many as a way to reduce costs in space programmes, as the space industry is seen as a decreasing costs industry, this is not a problem-free process. Commercialisation of space has affected the US and European space industries and policies in two major ways. The first is that the public sector actively encourages mergers and acquisitions of major contractors, confined, however, within the geographical borders of the US and Europe. This follows largely from the perceived benefits of economies of size when competing in global commercial markets. The second is the formation of an increasing number of public-private partnerships (PPPs) in space programmes and a more `cosy' relationship between the two within a public-assistance strategic trade theoretic framework. As ESA's contracting policy of `juste retour' is marked by limited competition, the paper focuses on the case of NASA, which is expected to be more pro- competitive, to examine the impact of commercialisation. With the use of quantitative methods based on time series econometric analysis, the paper shows that NASA's contracting policy, results in increasingly less competition and more rent-favouring contracting. This is attributed to the decreasing number of major contractors in conjunction with the preferential treatment of the domestic space industry (`Buy American'). The results of the paper verify that the support of the domestic space industry in commercial and public space markets results in inefficient contracting policies, with NASA facing the conflicting tasks of a stated policy of enhancing competition and efficiency in contracting, as well as, supporting the competitiveness of the domestic space industry. The paper concludes with an analysis and assessment of solutions to this

2015-07-01

Full Text Available On 06.24.2014 Albania was granted the status of candidate country. The foreign ministers of the 28 European Union member states decided unanimously to grant the candidate status for Albania. After receiving the status of “candidate country” for EU membership, the institutional relations with European international bodies are becoming stronger. One of these institutions, which during this time has increased its authority with Albania, is the European Parliament. In this paper will be analyzed the composition, competences and functioning of this particular institution, which is not only important for the future of the European Union and its Member States, but also for those who aim to join in. The study will be based on decisions made by this legislative body, as the only direct representative of the citizens of the European Union, and the impact they have on the performance and functioning of the Member States and the EU itself. In order to verify the validity of these claims, the analysis aims to assess the scope of the legislative function of the European Parliament post-Lisbon, examining its participation in the EU lawmaking both from the point of view of quantity and quality in over the past legislatures. Particular attention has been given to the examination of the changes that have taken place with the entry into force of the Lisbon Treaty, and the areas most affected. We will finally look at the work and contribution of the European Parliament, through the instruments at his disposal, on behalf of Albania’s progress towards full accession in the European Union.

A Grand Vision for European Astronomy

, community-based Infrastructure Roadmap, crucial to keep Europe at the forefront of astronomical research," says de Zeeuw. ESO PR Photo 44a/07 European astronomy today is fully competitive on the global scene and is at the forefront in many domains with such breakthroughs as the first detection of a planet around a sun-like star, the successful landing on Titan, the proof that a massive black hole exists in the centre of our own Galaxy, the discovery of gravitational arcs around galaxy clusters, and the proof that most Gamma Ray Bursts are caused by huge exploding stars. The rise of European astronomy to this top position by the end of last century has been achieved through extensive cooperation and coordination of efforts, in particular through ESO for optical astronomy and ESA for space astronomy. To strengthen this position and to extend it to all branches of astronomy and all nations of the new Europe, a group of European funding agencies set up the ASTRONET programme with the goal to establish a comprehensive long-term development plan of European astronomy. ASTRONET therefore covers all astrophysical domains from cosmology to the Solar system, and every observing window, from space and from the ground, and from electromagnetic radiation to particles and gravitational waves. It addresses the whole astronomical 'food chain' from infrastructure and technology development to observation, data access, modelling and theory, and the human resources needed to make it all work. This effort is quite similar in scope to the 'decadal surveys' conducted in the USA over the last half-century, but unlike its American counterpart, ASTRONET was set up directly by the national funding agencies, with strong support from the European Commission. "A shared long-term Science Vision for European astronomy is the fundamental first step in the process, soon to be followed by a detailed infrastructure and technology development roadmap," says Johannes Andersen (NOTSA, Denmark), the ASTRONET

Erasing lines: Territorial cooperation, sovereignty and European construction (1948-1980

Full Text Available The process of European integration, controlled by nation-states, has generated supranational dynamics affecting the sovereignty of the states themselves. The border, one of the most visible symbols of national sovereignty, has been overcome in physical and economic —though not legal— terms. This was achieved first, by the creation of the customs union and later by the single market. In this area of overcoming boundaries, local and regional actors have played a leading role through territorial and cross-border cooperation. Using bibliographical and documentary sources, mainly from the European Navigator, this study analyzes the origins of the early cooperation structures located on the bank of the Rhine, in Frisia and in the Nordic countries. We specifically focus on who these actors were, what their motivations, goals and characteristics were, their Europeanization and the role of the nation-states. The conclusion reached leads us to argue that, if in fact new transnational spaces are established, the objectives of these structures have more to do with local economic development than with identity factors that challenge existing national sovereignty.

1987-05-01

The European Community was established in 1951 to reconcile France and Germany after World War II and to make possible the eventual federation of Europe. By 1986, there were 12 member countries: France, Italy, Belgium, the Federal Republic of Germany, Luxembourg, the Netherlands, Denmark, Ireland, the United Kingdom, Greece, Spain, and Portugal. Principal areas of concern are internal and external trade, agriculture, monetary coordination, fisheries, common industrial and commercial policies, assistance, science and research, and common social and regional policies. The European Community has a budget of US$34.035 billion/year, funded by customs duties and 1.4% of each member's value-added tax. The treaties establishing the European Community call for members to form a common market, a common customs tariff, and common agricultural, transport, economic, and nuclear policies. Major European Community institutions include the Commission, Council of Ministers, European Parliament, Court of Justice, and Economic and Social Committee. The Community is the world's largest trading unit, accounting for 15% of world trade. The 2 main goals of the Community's industrial policy are to create an open internal market and to promote technological innovation in order to improve international competitiveness. The European Community aims to contribute to the economic and social development of Third World countries as well.

Raising European Citizens: Constructing European Identities in French and English Textbooks

Directory of Open Access Journals (Sweden)

Inari Sakki

Full Text Available Schools play a pivotal role in the formation of identities and in the political socialization of youth. This study explores the social representations of European integration in French and English school textbooks and shows how the social representations are discursively used to construct national and European identities. By analysing the history and civics textbooks of major educational publishers, this study aims to demonstrate how European integration is understood, made familiar and concretized in the school textbooks of the two influential but different European countries. The findings suggest some shared and some diverse patterns in the way the two European countries portray and construct the political project of European integration. These representations, constructed around French Europe in French textbooks and ambivalent Europe in English textbooks, share the images of a strong European economy and a French-led political Europe. However, they position themselves differently with respect to the United States, motivation for the European unification process and the significance of common values and heritage. In both countries textbooks draw upon memories that are important for group identity. While the French textbooks make European integration meaningful in reference to a shared post-war collective memory and to a cultural memory based on a more ancient idea of Europe, shared values and heritage, the English textbooks anchor it more strongly to domestic policy.

Istanbul and the Heritage of the European City

Full Text Available “The society, which has produced form and shape of the traditional European city does not exist any more.” (Siebel 2004 Raising our conscience on this circumstance as it as been pointed to by Walter Siebel does make planning issues re-appear in the light of knowledge that problems tackled on the basis of realities no longer there, are not going to be solved. In spite of this knowledge however the discourse around the European city seems to narrow a perspective to fully grasp reasons for the stagnation of its spatial form in the backdrop of socio-cultural change. For this reason I want to include another city into the discussion, which by Siebel’s definition is a typical European city and therefore fit for a comparison with postfeudal European Cities around which Siebel´s theory is oriented. At the same time however Istanbul lifts itself from an euro-centred context by never having fully internalized culturally the mechanisms of spatial production based on western capitalism. In this contribution I will look at the role of this cultural heritage for the prevalence of spatial specificities. Without the cultural backbone of civic management and social redistribution Istanbul is now, in the late stage of capitalism, a city that has integrated the global tendencies of neo-liberalism directly into the production of urban space. It demonstrates therefore clearly the realities of society through the characteristics of the built environment. Possibly the image that prevails with its new more explicit forms of urban segregation and the rise of gated communities is a glimpse upon social realities which have gained validity also for the European City.

The state of Health in All policies (HiAP) in the European Union: potential and pitfalls.

Science.gov (United States)

Koivusalo, Meri

2010-06-01

Health in All Policies (HiAP) was formally legitimated as a European Union (EU) approach in 2006. It resulted from more long-term efforts to enhance action on considering health and health policy implications of other policies, as well as recognition that European-level policies affect health systems and scope for health-related regulation at national level. However, implementation of HiAP has remained a challenge. European-level efforts to use health impact assessment to benefit public health and health systems have not become strengthened by the new procedures. And, as a result of the Lisbon Treaty, European-level policy-making is expected to become more important in shaping national policies. HiAP has at European level remained mostly as rhetoric, but legitimate health arguments and provides policy space for health articulation within EU policy-making. HiAP is a broader approach than health impact assessment and at European level requires consideration of mechanisms that recognise the nature of European policy-making, as well as extending from administrative tools to increased transparency, accountability and scope for health and health policy-related arguments within political decision-making in the EU.

2012-07-01

Following the severe accidents which started in the Fukushima Dai-ichi NPP on 11 March 2011, the European Council requested that a comprehensive safety and risk assessment, in light of preliminary lessons learned, be performed on all EU nuclear plants. Therefore, stress tests and peer review assessing natural initiating events, the loss of safety systems and severe accident management have been performed in the 15 European Union countries with nuclear power plants as well as Switzerland and Ukraine. The final peer review report of the European Nuclear Safety Regulators Group (ENSREG) highlights four main areas for improvement to be explored across Europe: 1. Development by the Western European Nuclear Regulators' Association (WENRA), with the contribution of the best available EU expertise, of a European guidance on assessment of natural hazards and margins; 2. Importance of Periodic Safety Review to be underlined by ENSREG; 3. Expeditious implementation of the recognised measures to protect containment integrity; 4. Prevention of accidents resulting from natural hazards and limitation of their consequences. The peer review of the European stress tests was completed in April 2012. In their conclusive statement issued 26 April 2012, the national European regulators and the European Commission as European Nuclear Safety Regulators Group (ENSREG) required that follow-up would occur by way of an ENSREG action plan. Country specific action plans will be developed and peer review workshop will be organised to share lessons learned on the implementation of post-Fukushima safety improvements.

The German Aerospace Center (DLR) and the European Southern Observatory (ESO) performed a measurement campaign together in April and July 2016 at Teide-Observatory (Tenerife), with the support of the European Space Agency (ESA), to investigate the use of laser guide stars (LGS) in ground to space optical communications. Atmospheric turbulence causes strong signal fluctuations in the uplink, due to scintillation and beam wander. In space communications, the use of the downlink channel as reference for pointing and for pre-distortion adaptive optics is limited by the size of the isokinetic and isoplanatic angle in relation to the required point-ahead angle. Pointing and phase errors due to the decorrelation between downward and upward beam due to the point-ahead angle may have a severe impact on the required transmit power and the stability of the communications link. LGSs provide a self-tailored reference to any optical ground-to-space link, independently of turbulence conditions and required point-ahead angle. In photon-starved links, typically in deep-space scenarios, LGSs allow dedicating all downlink received signal to communications purposes, increasing the available link margin. The scope of the joint DLR-ESO measurement campaign was, first, to measure the absolute value of the beam wander (uplink-tilt) using a LGS, taking a natural star as a reference, and, second, to characterize the decrease of correlation between uplink-tilt and downlink-tilt with respect to the angular separation between both sources. This paper describes the experiments performed during the measurement campaigns, providing an overview of the measured data and the first outcomes of the data post-processing.

Which Wild Aardvarks Are Most Suitable for Outdoor Enclosures in Zoological Gardens in the European Union?

Science.gov (United States)

Patoka, Jiří; Vejtrubová, Markéta; Vrabec, Vladimír; Masopustová, Renata

2018-01-01

The aardvark is popular in many zoological gardens in the European Union. These creatures are nocturnal, and aardvarks in the wild are known to walk distances of 4 km to 7 km per night. Despite what is known about their biology, most aardvarks are kept in zoological gardens in indoor enclosures with little space for movement. This lack of space leads to a tendency toward obesity and compromised welfare. With their wide distribution in Sub-Saharan Africa, aardvarks are perceived as thermophilic nonhuman animals. Nevertheless, some records suggest they may be able to adapt to colder climates and can be active outside their burrows when temperatures fall to 2°C. These findings suggest there may be a wild African population that is suitable for partial outdoor keeping under European climatic conditions. Therefore, a climate match was computed between the source area with aardvark occurrence and a target area of the European Union. Data revealed that the Free State, a South African province, was the area with the best climate similarity, and aardvarks from this area are recommended as suitable for the aforementioned purpose.

Design and Development of a Model to Simulate 0-G Treadmill Running Using the European Space Agency's Subject Loading System

Develop a model that simulates a human running in 0 G using the European Space Agency s (ESA) Subject Loading System (SLS). The model provides ground reaction forces (GRF) based on speed and pull-down forces (PDF). DESIGN The theoretical basis for the Running Model was based on a simple spring-mass model. The dynamic properties of the spring-mass model express theoretical vertical GRF (GRFv) and shear GRF in the posterior-anterior direction (GRFsh) during running gait. ADAMs VIEW software was used to build the model, which has a pelvis, thigh segment, shank segment, and a spring foot (see Figure 1).the model s movement simulates the joint kinematics of a human running at Earth gravity with the aim of generating GRF data. DEVELOPMENT & VERIFICATION ESA provided parabolic flight data of subjects running while using the SLS, for further characterization of the model s GRF. Peak GRF data were fit to a linear regression line dependent on PDF and speed. Interpolation and extrapolation of the regression equation provided a theoretical data matrix, which is used to drive the model s motion equations. Verification of the model was conducted by running the model at 4 different speeds, with each speed accounting for 3 different PDF. The model s GRF data fell within a 1-standard-deviation boundary derived from the empirical ESA data. CONCLUSION The Running Model aids in conducting various simulations (potential scenarios include a fatigued runner or a powerful runner generating high loads at a fast cadence) to determine limitations for the T2 vibration isolation system (VIS) aboard the International Space Station. This model can predict how running with the ESA SLS affects the T2 VIS and may be used for other exercise analyses in the future.

In 2001 the first private man, Denis Tito,visited the ISS and the second private man, Mark Shuttleworth is following him. The gate towards the commercial utilization of manned space flight has been pushed open. Space pioneers as Wernher von Braun and Sir Arthur C. Clarke had the dream that one day a space station in earth orbit will host tourists. It is evident that the ISS is not designed to host tourists. Therefore the dream of the pioneers is still open. By asking the question "how should a space station should look like to host tourists?", the German Aerospace Society DGLR e.V. organized a contest under the patronage of Mr. Joerg Feustel-Buechl, the Director of Manned Spaceflight and Microgravity, European Space Agency (ESA) in April 2001. Because the definition and design of living space is the content of architecture the approach was to gather new ideas from young architects in cooperation with space experts. This contest was directed at students of architecture and the task set was to design a hotel for the earth orbit and to accommodate 220 guests. The contest got the name "Early Bird - Visions of a Space Hotel". The results and models of the student's work were shown in an exhibition in Hamburg/Germany, which was open to the public from September 19th till October 20th 2001. During the summer term of 2001 seventeen designs were completed. Having specialists, as volunteers, in the field of space in charge meant that it could be ensured that the designs reflected a certain possibility of being able to be realized. Within this interdisciplinary project both parties learned from each other. The 17 different designs were focused on the expectations and needs of a future space tourist. The designs are for sure not feasible today, but the designs are in that sense realistic that they could be

2009-11-01

More and more plastic encapsulated microcircuits (PEMs) are used in space missions to achieve high performance. Since PEMs are designed for use in terrestrial operating conditions, the successful usage of PEMs in space harsh environment is closely related to reliability issues, which should be considered firstly. However, there is no ready-made methodology for PEMs in space applications. This paper discusses the reliability for the usage of PEMs in space. This reliability analysis can be divided into five categories: radiation test, radiation hardness, screening test, reliability calculation and reliability assessment. One case study is also presented to illuminate the details of the process, in which a PEM part is used in a joint space program Double-Star Project between the European Space Agency (ESA) and China. The influence of environmental constrains including radiation, humidity, temperature and mechanics on the PEM part has been considered. Both Double-Star Project satellites are still running well in space now.

Thermal/vacuum measurements of the Herschel space telescope by close-range photogrammetry

2017-11-01

In the frame of the development of a videogrammetric system to be used in thermal vacuum chambers at the European Space Research and Technology Centre (ESTEC) and other sites across Europe, the design of a network using micro-cameras was specified by the European Space agency (ESA)-ESTEC. The selected test set-up is the photogrammetric test of the Herschel Satellite Flight Model in the ESTEC Large Space Simulator. The photogrammetric system will be used to verify the Herschel Telescope alignment and Telescope positioning with respect to the Cryostat Vacuum Vessel (CVV) inside the Large Space Simulator during Thermal-Vacuum/Thermal-Balance test phases. We designed a close-range photogrammetric network by heuristic simulation and a videogrammetric system with an overall accuracy of 1:100,000. A semi-automated image acquisition system, which is able to work at low temperatures (-170°C) in order to acquire images according to the designed network has been constructed by ESA-ESTEC. In this paper we will present the videogrammetric system and sub-systems and the results of real measurements with a representative setup similar to the set-up of Herschel spacecraft which was realized in ESTEC Test Centre.

A cooperative program between the French Centre National d'Etudes Spatiales (CNES) and the Commissariat a l'Energie Atomique (CEA) was initiated in 1983, to investigate the possible development of 20 to 200 kWe space nuclear power systems to be launched by the next version of the European launcher, Ariane V. After completion in 1986 of preliminary conceptual studies of a reference 200 kWe turbo-electric power system, an additional 3 year study phase was decided, with the double objective of assessing the potential advantage of nuclear power systems versus solar photovoltaic or dynamic systems in the 20 kWe power range, and comparing various reactor candidate technologies and system options for 20 kWe space nuclear power systems, likely to meet the projected energy needs of future European space missions. A comprehensive program including conceptual design studies, operating transient analyses and technology base assessment, is currently applied to a few reference concepts of 20 kWe nuclear Brayton and thermoelectric systems, in order to establish sound technical and economical bases for selecting the design options and the development strategy of a first space nuclear power system in Europe

For over twenty years, scientists, engineers, technicians, and other personnel have been working on the next generation space telescope. As a partnership between NASA (National Aeronautics and Space Administration), CSA (Canadian Space Agency), and ESA (European Space Angency), the James Webb Space Telescope will complement the previous research performed by the Hubble by utilizing a larger primary mirror, which will also be optimized for infrared wavelengths. This combination will allow JWST to collect data and take images of light having traveled over 13.7 billion light years. This presentation will focus on the mission, as well as the contamination control challenges during the integration and testing in the NASA Goddard Spacecraft Systems Development and Integration Facility (SSDIF), one of the largest cleanrooms in the world. Additional information will be presented regarding space simulation testing down to a cool 20 degrees Kelvin [-424 degrees Fahrenheit] that will occur at Johnson Space Center in Houston, TX, and more testing and integration to happen at Northrop Grumman Corp., in Redondo Beach, CA. Launch of the JWST is currently scheduled for the spring of 2019 at Ariane Spaceport in French Guiana, South America.

Aircraft parabolic flights repetitively provide up to 23 s of reduced gravity during ballistic flight manoeuvres. Parabolic flights are used to conduct short microgravity investigations in Physical and Life Sciences and in Technology, to test instrumentation prior to space flights and to train astronauts before a space mission. The use of parabolic flights is complementary to other microgravity carriers (drop towers, sounding rockets), and preparatory to manned space missions on board the International Space Station and other manned spacecraft, such as Shenzhou and the Chinese Space Station CSS. The European Space Agency (ESA), the 'Centre National d'Etudes Spatiales' (CNES, French Space Agency) and the 'Deutsches Zentrum für Luft- und Raumfahrt e.V.' (DLR, the German Aerospace Centre) have used the Airbus A300 ZERO-G for research experiments in microgravity, and at Moon and Mars gravity levels, from 1997 until October 2014. The French company Novespace, a subsidiary of CNES, based in Bordeaux, France, is in charge of the organisation of Airbus A300 ZERO-G flights. A total of 104 parabolic flight campaigns have been organised by ESA, CNES and DLR since 1997, including 38 ESA, 34 CNES and 23 DLR microgravity campaigns, two Joint European ESA-CNES-DLR Partial-g Parabolic Flight Campaigns, and seven ESA Student campaigns. After 17 years of good and loyal services, this European workhorse for microgravity research in parabolic flights has been retired. The successor aircraft, the Airbus A310 ZERO-G, is being prepared for a first ESA-CNES-DLR cooperative campaign in Spring 2015. This paper looks back over 17 years of microgravity research in parabolic flights with the A300 ZERO-G, and introduces the new A310 ZERO-G that will be used from 2015 onwards.

We further show how the “translation” of international norms to a domestic context has worked to reinforce the original institutional setup, dating back to the mid-1950s.

Pedersen, K. S.

1983-01-01

International cooperative efforts undertaken by NASA are evaluated and consideration is given to the proposed space station. The Shuttle RMS and Spacelab were constructed through efforts of Canadian and European companies and the ESA. Landsat, with its widely dispersed technology and data, has encouraged international access to its capabilities and start-up of follow-on programs in other countries. Space station planning is proceeding with a view to worldwide utilization of space and to the commitment and resources other nations are willing to place in the station. It is conceded that administrative difficulties will arise if the space station is a completely international effort guided by NASA. Additionally, concern will be present for technology leaks, national security implications on the space station, and reasonably fulfilling the benefits expected by those who become partners in the construction and operation of the station.

Deep space exploration is in the agenda of the major space agencies worldwide and at least the European Space Agency (SMART & Aurora Programs) and the American NASA (New Millennium Program) have set up programs to allow the development and the demonstration of technologies that can reduce the risks...... and the costs of the deep space missions. Navigation is the Achilles' heel of deep space. Being performed on ground, it imposes considerable constraints on the system and the operations, it is very expensive to execute, especially when the mission lasts several years and, above all, it is not failure tolerant...... to determine the orbit of a spacecraft autonomously, on-board and without any a priori knowledge of any kind. The solution is robust, elegant and fast. This paper presents the preliminary performances obtained during the ground tests. The results are very positive and encouraging....

Sentinel-5 is an Earth Observation instrument to be flown on the Metop Second Generation (Metop-SG) satellites with the fundamental objective of monitoring atmospheric composition from polar orbit. The Sentinel-5 instrument consists of five spectrometers to measure the solar spectral radiance backscattered by the earth atmosphere in five bands within the UV (270nm) to SWIR (2385nm) spectral range. Data provided by Sentinel-5 will allow obtaining the distribution of important atmospheric constituents such as ozone, on a global daily basis and at a finer spatial resolution than its precursor instruments on the first generation of Metop satellites. The launch of the first Metop-SG satellite is foreseen for 2021. The Sentinel-5 instrument is being developed by Airbus DS under contract to the European Space Agency. The Sentinel-5 mission is part of the Space Component of the Copernicus programme, a joint initiative by ESA, EUMETSAT and the European Commission. The Preliminary Design Review (PDR) for the Sentinel-5 development was successfully completed in 2015. This paper provides a description of the Sentinel-5 instrument design and data calibration.

Quantum finance Hamiltonian for coupon bond European and barrier options.

Science.gov (United States)

Baaquie, Belal E

2008-03-01

Coupon bond European and barrier options are financial derivatives that can be analyzed in the Hamiltonian formulation of quantum finance. Forward interest rates are modeled as a two-dimensional quantum field theory and its Hamiltonian and state space is defined. European and barrier options are realized as transition amplitudes of the time integrated Hamiltonian operator. The double barrier option for a financial instrument is "knocked out" (terminated with zero value) if the price of the underlying instrument exceeds or falls below preset limits; the barrier option is realized by imposing boundary conditions on the eigenfunctions of the forward interest rates' Hamiltonian. The price of the European coupon bond option and the zero coupon bond barrier option are calculated. It is shown that, is general, the constraint function for a coupon bond barrier option can -- to a good approximation -- be linearized. A calculation using an overcomplete set of eigenfunctions yields an approximate price for the coupon bond barrier option, which is given in the form of an integral of a factor that results from the barrier condition times another factor that arises from the payoff function.

Are we Europeans?: Correlates and the relation between national and European identity

Full Text Available Researches of the correlates of the national identity are plentiful both in Serbian and foreign literature. However, in the past decade or so, a new social identity starts to make its way into the researches of the social psychologists-European identity or the sense of belonging to the Europe and the Europeans. This paper deals with the relation between national and European identity, as well as with the correlates of both of these, or one of them. The sample consisted of 451 subjects, all residents of major cities in the Vojvodina region (northern Serbia, divided into several categories-ethnicity (Serbs and Hungarians, educational level (primary and secondary school or University degree, gender and age. Several scales have been used: Cinnirela's national and European identity scale, Collective self-esteem scale, scale measuring attitudes towards the European integration-STEIN and Social dominance orientation scale-SDO. The questionnaire with the demographic characteristics has also been the part of the instrument. The research has been conducted in 2005 and 2006 in the all of the major Vojvodinian cities. Results show the relation between national and European identity is foggy, but general conclusion is that we can observe them as independent identities. The correlates of the national identity were ethnicity, high social dominance orientation, high collective self-esteem and negative attitude towards the European integrations. Correlates of the European identity were fewer: ethnicity, positive attitude towards the European integration and low social dominance orientation.

Earth Observation data and remote sensing technologies have been maturing into useful tools that can be utilised by local authorities and businesses to aid in activates such as monitoring climate change trends and managing agricultural land and water uses. The European Earth observation programme Copernicus, previously known as GMES (Global Monitoring for Environment and Security), provides the means to collect and process multi-source EO and environmental data that supports policy developments at the European level. At the regional and local level, the Copernicus programme has been initiated through Regional Contact Office (RCO), which provide knowledge, training, and access to expertise both locally and at a European level through the network of RCOs established across Europe in the DORIS_Net (Downstream Observatory organised by Regions active In Space - Network) project (Grant Agreement No. 262789 Coordination and support action (Coordinating) FP7 SPA.2010.1.1-07 "Fostering downstream activities and links with regions"). In the East Midlands UK RCO, educational and training workshops and modules have been organised to highlight the wider range of tools and application available to businesses and local authorities in the region. Engagement with businesses and LRA highlighted the need to have a tiered system of training to build awareness prior to investigating innovative solutions and space technology uses for societal benefits. In this paper we outline education and training programmes which have been developed at G-STEP (GMES - Science and Technology Education Partnership), University of Leicester, UK to open up the Copernicus programme through the Regional Contact Office to downstream users such as local businesses and LRAs. Innovative methods to introduce the operational uses of Space technologies in real cases through e-learning modules and web-based tools will be described and examples of good practice for educational training in these sectors will be

Active laser remote sensing from space is considered an important step forward in the understanding of the processes which regulate weather and climate changes. The planned launching into polar orbit in the late 1990s of a series of dedicated Earth observation satellites offer new possibilities for flying lidar in space. Among the various lidar candidates, ESA has recognized in the backscattering lidar and Doppler wind lidar the instruments which can most contribute to the Earth observation program. To meet the schedule of the on-coming flight opportunities, ESA has been engaged over the past years in a preparatory program aimed to define the instruments and ensure timely availability of the critical components. This paper reviews the status of the ongoing developments and highlights the critical issues addressed.

A Study on Re-entry Predictions of Uncontrolled Space Objects for Space Situational Awareness

Science.gov (United States)

Choi, Eun-Jung; Cho, Sungki; Lee, Deok-Jin; Kim, Siwoo; Jo, Jung Hyun

2017-12-01

The key risk analysis technologies for the re-entry of space objects into Earth’s atmosphere are divided into four categories: cataloguing and databases of the re-entry of space objects, lifetime and re-entry trajectory predictions, break-up models after re-entry and multiple debris distribution predictions, and ground impact probability models. In this study, we focused on re- entry prediction, including orbital lifetime assessments, for space situational awareness systems. Re-entry predictions are very difficult and are affected by various sources of uncertainty. In particular, during uncontrolled re-entry, large spacecraft may break into several pieces of debris, and the surviving fragments can be a significant hazard for persons and properties on the ground. In recent years, specific methods and procedures have been developed to provide clear information for predicting and analyzing the re-entry of space objects and for ground-risk assessments. Representative tools include object reentry survival analysis tool (ORSAT) and debris assessment software (DAS) developed by National Aeronautics and Space Administration (NASA), spacecraft atmospheric re-entry and aerothermal break-up (SCARAB) and debris risk assessment and mitigation analysis (DRAMA) developed by European Space Agency (ESA), and semi-analytic tool for end of life analysis (STELA) developed by Centre National d’Etudes Spatiales (CNES). In this study, various surveys of existing re-entry space objects are reviewed, and an efficient re-entry prediction technique is suggested based on STELA, the life-cycle analysis tool for satellites, and DRAMA, a re-entry analysis tool. To verify the proposed method, the re-entry of the Tiangong-1 Space Lab, which is expected to re-enter Earth’s atmosphere shortly, was simulated. Eventually, these results will provide a basis for space situational awareness risk analyses of the re-entry of space objects.

Planetary Space Weather Services for the Europlanet 2020 Research Infrastructure

Science.gov (United States)

André, Nicolas; Grande, Manuel

2016-04-01

Under Horizon 2020, the Europlanet 2020 Research Infrastructure (EPN2020-RI) will include an entirely new Virtual Access Service, WP5 VA1 "Planetary Space Weather Services" (PSWS) that will extend the concepts of space weather and space situational awareness to other planets in our Solar System and in particular to spacecraft that voyage through it. VA1 will make five entirely new 'toolkits' accessible to the research community and to industrial partners planning for space missions: a general planetary space weather toolkit, as well as three toolkits dedicated to the following key planetary environments: Mars (in support ExoMars), comets (building on the expected success of the ESA Rosetta mission), and outer planets (in preparation for the ESA JUICE mission to be launched in 2022). This will give the European planetary science community new methods, interfaces, functionalities and/or plugins dedicated to planetary space weather in the tools and models available within the partner institutes. It will also create a novel event-diary toolkit aiming at predicting and detecting planetary events like meteor showers and impacts. A variety of tools (in the form of web applications, standalone software, or numerical models in various degrees of implementation) are available for tracing propagation of planetary and/or solar events through the Solar System and modelling the response of the planetary environment (surfaces, atmospheres, ionospheres, and magnetospheres) to those events. But these tools were not originally designed for planetary event prediction and space weather applications. So WP10 JRA4 "Planetary Space Weather Services" (PSWS) will provide the additional research and tailoring required to apply them for these purposes. The overall objectives of this Joint Research Aactivities will be to review, test, improve and adapt methods and tools available within the partner institutes in order to make prototype planetary event and space weather services operational in
