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-μm absorption line instead of the usual 2.87-μm line due to the OH-stretch vibration

Vantagens Competitivas em Instituições de Ensino Superior: proposta e teste de um modelo

A presente investigação teve como objetivo propor e testar um modelo conceptual que avalie a gestão estratégica de uma instituição de ensino superior (IES). Neste sentido, o estudo procurou unir três tracionais abordagens teóricas ligadas a estratégias empresariais, adaptando-as ao setor educacional: as Teorias de Competitividade, a Teoria dos Recursos e Capacidades e a Teoria dos Stakeholders. Com o apoio teórico destas três teorias, identificou-se os públicos ligados a estas instituições e os fatores internos e externos às organizações educacionais que influenciam a identificação das vantagens competitivas. O modelo desenvolvido foi testado e validado em um estudo de caso realizado com uma universidade brasileira. Os dados evidenciam uma adequação das variáveis de medição propostas no modelo à instituição estudada. A principal contribuição do estudo foi a descoberta de indicadores de medição de cada variável do modelo proposto.Vantagens competitivas, Competitividade educacional, Serviço educacional, Ensino Superior, Gestão de universidades

Photoconductivity Parameters In Lithium Niobate

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

Exploring the benefits of doll play through neuroscience

It has long been hypothesized that pretend play is beneficial to social and cognitive development. However, there is little evidence regarding the neural regions that are active while children engage in pretend play. We examined the activation of prefrontal and posterior superior temporal sulcus (pSTS) regions using near-infrared spectroscopy while 42 4- to 8-year-old children freely played with dolls or tablet games with a social partner or by themselves. Social play activated right prefrontal regions more than solo play. Children engaged the pSTS during solo doll play but not during solo tablet play, suggesting they were rehearsing social cognitive skills more with dolls. These findings suggest social play utilizes multiple neural regions and highlight how doll play can achieve similar patterns of activation, even when children play by themselves. Doll play may provide a unique opportunity for children to practice social interactions important for developing social-emotional skills, such as empathy

Creep analysis of a GRP cylinder under hydrostatic test / Análise de fluência de um cilindro GRP sob teste hidrostático

The GRP (Glass Reinforced Polymer) has been widely used in several industrial applications mainly due to its low cost, high availability, and easy manufacturing process. The matrix made by a combination of glass fibers and epoxy offers good engineering properties for the composite material. This study aims to investigate the creep behavior of a glass fiber/epoxy composite cylinder when it was subjected to hydrostatic pressure at room temperature, and when heated at 50ºC. The geometrical viscoelastic deformation was identified by processing signal data positioned on the cylinder surface. Then, electronic data processing was performed to obtain the characteristic of the creep phase phenomenon attributed to this polymeric composite. The cylindrical specimen has been manufactured using a 4-axis CNC (Computer Numeric Control) filament winding machine, which is equipment designed to produce cylindrical components in the composite industry. A creep test was performed by submitting the cylinder to a hydrostatic load for 500 hours, with a controlled injection of fluid up to a 50 bar pressure. Moreover, fiber volume fraction and composite density were determined to control de manufacturing parameters. The results showed that the glass transition temperature of the composite was 120°C. This also indicated a high level of reliability in the manufacturing parameters of the composite specimen. In the experiment carried out at 50ºC, the polymer matrix showed a loss of stiffness, which contributed to increased strain levels in the composite material. The structure did not show a significant creep effect after 500 hours, ensuring good dimensional and structural stability from the cylinder. Once the creep test finished, the cylinder was submitted to increase the pressure level to rupture. The microstructure was also evaluated using scanning electron microscopy (SEM). The SEM analyses presented a good agreement with the filament winding manufacturing parameters and showed the excellent quality of impregnation between glass fiber and epoxy resin applied on the cylinder specimen. The images presented evidence of an excellent adhesion of the fiber into the matrix, contributing to a good performance of the composite

Hyperfine interaction and magnetoresistance in organic semiconductors

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
