    This paper presents the problems concerning the organic food demand in Poland. It indicates the reasons for such small interest in this kind of food, the main motives of purchase, and the barriers of market development. It also shows the ways of developing the organic food market development

    Functional promoter polymorphism of the neuronal isoform of tryptophan hydroxylase (Tph2) in suicide

    Get PDF
    The association between suicide and G-703T polymorphism of the tryptophan hydroxylase 2 (TPH2), the rate-limiting enzyme in the biosynthesis of the neurotransmitter serotonin, was studied in a sample of 291 suicide victims and 280 healthy subjects of Croatian origin. No significant differences were found between the groups. Obtained results do not support involvement of the investigated polymorphism in the susceptibility to suicide completion

    EVA Radio DRATS 2011 Report

    Get PDF
    In the Fall of 2011, National Aeronautics and Space Administration (NASA) Glenn Research Center (GRC) participated in the Desert Research and Technology Studies (DRATS) field experiments held near Flagstaff, Arizona. The objective of the DRATS outing is to provide analog mission testing of candidate technologies for space exploration, especially those technologies applicable to human exploration of extra- terrestrial rocky bodies. These activities are performed at locations with similarities to extra-terrestrial conditions. This report describes the Extravehicular Activity (EVA) Dual-Band Radio Communication System which was demonstrated during the 2011 outing. The EVA radio system is designed to transport both voice and telemetry data through a mobile ad hoc wireless network and employs a dual-band radio configuration. Some key characteristics of this system include: 1. Dual-band radio configuration. 2. Intelligent switching between two different capability wireless networks. 3. Self-healing network. 4. Simultaneous data and voice communication

    Power, Avionics and Software - Phase 1.0:

    Get PDF
    This report describes Power, Avionics and Software (PAS) 1.0 subsystem integration testing and test results that occurred in August and September of 2013. This report covers the capabilities of each PAS assembly to meet integration test objectives for non-safety critical, non-flight, non-human-rated hardware and software development. This test report is the outcome of the first integration of the PAS subsystem and is meant to provide data for subsequent designs, development and testing of the future PAS subsystems. The two main objectives were to assess the ability of the PAS assemblies to exchange messages and to perform audio testing of both inbound and outbound channels. This report describes each test performed, defines the test, the data, and provides conclusions and recommendations

    802.16e System Profile for NASA Extra-Vehicular Activities

    Get PDF
    This report identifies an 802.16e system profile that is applicable to a lunar surface wireless network, and specifically for meeting extra-vehicular activity (EVA) data flow requirements. EVA suit communication needs are addressed. Design-driving operational scenarios are considered. These scenarios are then used to identify a configuration of the 802.16e system (system profile) that meets EVA requirements, but also aim to make the radio realizable within EVA constraints. Limitations of this system configuration are highlighted. An overview and development status is presented by Toyon Research Corporation concerning the development of an 802.16e compatible modem under NASA s Small Business Innovative Research (SBIR) Program. This modem is based on the recommended system profile developed as part of this report. Last, a path forward is outlined that presents an evolvable solution for the EVA radio system and lunar surface radio networks. This solution is based on a custom link layer, and 802.16e compliant physical layer compliant to the identified system profile, and a later progression to a fully interoperable 802.16e system

    Analyse De La Contribution D’une Entreprise Publique Dans La Croissance De L’économie Nationale Congolaise, Cas De La Société Nationale d’Assurances De 2019 A 2023

    Le terme d’investisseur institutionnel désigne les banques, compagnies d’assurances, caisses de retraites, fonds communs de placement. Généralement, ces actionnaires ne disposent que des participations très minoritaires (moins de 10%) dans les entreprises cotées.  Leur rôle est cependant majeur, car ces acteurs, dans une large mesure, définissent la valeur boursière des entreprisses.Les fonds d’assurances jouent un rôle important dans la vie économique d’un pays. En ce sens qu’ils permettent le financement des activités économiques,  surtout dans un environnement où l’assurance  est connue par tous. Jean Fourastié, souligne que « les  assurances contribuent au développent d’un pays au point de vue économique et social, en permettant l’intégration du processus d’intermédiation financière ».Le fonctionnement harmonieux de toute société, digne de ce nom, exige  une politique basée sur les facteurs  matériels, financiers, humains…  Lesquels reposent sur les besoins du personnel réellement identifiés.  Cependant, la SONAS, point focal de notre recherche  face au souci d’accomplir son objet social,  navigue dans un environnement où l’assurance n’est pas au quotidien de tous les congolais. Obstacle  conduisant ainsi l’entreprise dans un problème d’insuffisance des ressources et de sous-équipement.Face à cette situation, la SONAS doit se battre pour contribuer à la croissance économique de la République Démocratique du Congo. Le fonds d’assurances favorisent le financement de  l’économie, et contribue ainsi à la croissance économique, en d’autre terme, les compagnies d’assurances jouent le rôle d’intermédiaire financière.Notre préoccupation dans cette  étude est de savoir quelle est la hauteur de la contribution de la SONAS, à la richesse produite par la RDC où l’assurance n’est pas monnaie courante pendant la période considérée ? En d’autres termes, par quel mécanisme la SONAS qui est une entreprise publique peut-elle contribuer à la croissance de l’économie de la République Démocratique du Congo, alors que  la notion même d’assurance pose encore problème ?L’intérêt de ce sujet est situé sur deux niveaux dont d’une part le niveau théorique et d’autre part le niveau pratique. Du point de vue théorique, ce travail  constitue une base de données pour les chercheurs soucieux de comprendre comment fonctionne la SONAS. Du point de vue pratique, ce travail  apporte quelques pistes de solutions pouvant permettre l’amélioration du secteur des assurances en République Démocratique du Congo
