    The Study of Global Burden of Diseaase Cancer Collaboration shown In 2015, there were 17.5 million cancer cases worldwide and 8.7 million deaths. Aims of this research to find out the knowledge level and behavior the female students of medicine and pharmacy Uncen in efforts prevention of cervical cancer. This research is non experimental research which is analyzed descriptively. Cross sectionel design where data collection was done only one and data collection in August 2017 by survey method and questionnaire as research instrument. The location of the research was done in the faculty of medicine and program study of pharmacy Cenderawasih University. The results obtained from this study were total of 359 female students, age 22 respondents (23.12%), unmarried 98.89%, respondents from jayapura, living with parents, often discussing with family, especially mother, and they talked about reproductive health. the most respondents get information about cervical cancer prevention from lecturer's subjects that is 63,79%, electronic media 57,94% and 55,99% get information from print media. The conclusion of this research is the level of female student knowledge about cervical cancer, cervical cancer prevention and cervical cancer prevention behavior of female students of Faculty of Medicine and Pharmacy study program of Cenderawasih University is considered good

    Increased Optical Damage Resistance In Lithium Niobate

    We have confirmed greatly improved resistance to photorefractive damage in compositions of lithium niobate containing 4.5 at. % MgO or more. Holographic diffraction measurements of photorefraction demonstrated that the improved performance is due to a hundredfold increase in the photoconductivity, rather than a decrease in the Glass current. The diffraction efficiency shows an Arrhenius dependence on temperature, with an activation energy of 0.1 eV for the damage-resistant compositions, compared with 0.5 eV for undoped or low-magnesium compositions. The damage-resistant compositions are distinguished by a 2.83-Ī¼m absorption line instead of the usual 2.87-Ī¼m line due to the OH-stretch vibration

    A presente investigaĆ§Ć£o teve como objetivo propor e testar um modelo conceptual que avalie a gestĆ£o estratĆ©gica de uma instituiĆ§Ć£o de ensino superior (IES). Neste sentido, o estudo procurou unir trĆŖs tracionais abordagens teĆ³ricas ligadas a estratĆ©gias empresariais, adaptando-as ao setor educacional: as Teorias de Competitividade, a Teoria dos Recursos e Capacidades e a Teoria dos Stakeholders. Com o apoio teĆ³rico destas trĆŖs teorias, identificou-se os pĆŗblicos ligados a estas instituiƧƵes e os fatores internos e externos Ć s organizaƧƵes educacionais que influenciam a identificaĆ§Ć£o das vantagens competitivas. O modelo desenvolvido foi testado e validado em um estudo de caso realizado com uma universidade brasileira. Os dados evidenciam uma adequaĆ§Ć£o das variĆ”veis de mediĆ§Ć£o propostas no modelo Ć  instituiĆ§Ć£o estudada. A principal contribuiĆ§Ć£o do estudo foi a descoberta de indicadores de mediĆ§Ć£o de cada variĆ”vel do modelo proposto.Vantagens competitivas, Competitividade educacional, ServiƧo educacional, Ensino Superior, GestĆ£o de universidades

    Photoconductivity Parameters In Lithium Niobate

    Get PDF
    Measurements on a variety of doped (magnesium and/or iron) and undoped lithium niobate crystals in the oxidized state demonstrate an Arrhenius dependence of dark conductivity on reciprocal temperature between 460 and 590 K. All of the crystals had roughly the same conductivity and activation energy (1.21 eV) over the temperature range, implying that all have about the same free-carrier concentration and mobility. The enhanced photoconductivity of magnesium-doped lithium niobate is attributed to a greatly reduced trapping cross section of Fe3+ for electrons, the smaller cross section being due to a changed substitutional site for Fe3+. The Fe3+ trapping cross section is calculated from photoconductivity data to be of order 10-18 m2 in undoped lithium niobate. This implies a photoelectron lifetime of order 6x10-11 s in a relatively pure (2-ppm Fe) oxidized crystal

    Hyperfine interaction and magnetoresistance in organic semiconductors

    Full text link
    We explore the possibility that hyperfine interaction causes the recently discovered organic magnetoresistance (OMAR) effect. Our study employs both experiment and theoretical modelling. An excitonic pair mechanism model based on hyperfine interaction, previously suggested by others to explain magnetic field effects in organics, is examined. Whereas this model can explain a few key aspects of the experimental data, we, however, uncover several fundamental contradictions as well. By varying the injection efficiency for minority carriers in the devices, we show experimentally that OMAR is only weakly dependent on the ratio between excitons formed and carriers injected, likely excluding any excitonic effect as the origin of OMAR.Comment: 10 pages, 7 figures, 1 tabl
