    Este documento tem por objetivo descrever as diretrizes para o projeto da interface de entrada de dados do Sistema de InformaĆ§Ć£o Gerencial da Embrapa (SIGER), promovendo uma uniformidade visual dos elementos grĆ”ficos que o compoem. Como consequĆŖncia desta uniformidade, espera-se que todo o SIGER possua o mesmo padrĆ£o de interface grĆ”fica, o que irĆ” facilitar a interacĆ£o do usuĆ”rio com o sistema. SĆ£o estabelecidas orientaƧƵes para a disposiĆ§Ć£o de elementos grĆ”ficos na tela e a definiĆ§Ć£o de algumas das suas propriedades bĆ”sicas. Algumas caracteristicas gerais do ambiente Windows sao mantidas na aplicaĆ§Ć£o conforme a configuraĆ§Ć£o definida pelo usuĆ”rio, como exemplo cor das janelas ativa e inativa, texto da janela, texto da mensagem, cor do item de menu normal, desativado e selecionado.bitstream/item/76631/1/CNPTIA-COM.TEC.-4-98.pd

    Optical Spectroscopy of Bright Fermi LAT Blazars

    Get PDF
    We report on HET and Palomar 5 m spectroscopy of recently identified Ī³\gamma-ray blazars in the {\it Fermi} LAT Bright Source List. These data provide identifications for 10 newly discovered Ī³\gamma-ray flat spectrum radio quasars (FSRQ) and six new BL Lacs plus improved spectroscopy for six additional BL Lacs. We substantially improve the identification completeness of the bright LAT blazars and give new redshifts and zz constraints, new estimates of the black hole masses and new measurements of the optical SED.Comment: 8 pages, 5 figures, 2 tables.

    Multiwavelength Studies of PSR J1420-6048, a Young Pulsar in the Kookaburra

    We present X-ray, radio, and infrared observations of the 68 ms pulsar PSR J1420-6048 and its surrounding nebula, a possible counterpart of the gamma-ray source GeV J1417-6100/3EG J1420-6038. Pulsed X-ray emission at the radio period is marginally detected by ASCA from a source embedded in the hard spectrum X-ray nebula AX J1420.1-6049. At radio wavelengths, the pulsar is found to be strongly linearly and circularly polarized, and the polarization sweep is measured. A comparison of high resolution ATCA radio imaging of the Kookaburra's upper wing (G313.6+0.3), which contains the pulsar and the X-ray nebula, with infrared images suggests the radio emission is partly non-thermal.Comment: 8 pages, 4 figures, to appear in Astrophysical Journal Letter

    Este trabalho teve como objetivos relacionar os dados de temperatura e precipitaĆ§Ć£o (2000 a 2010) com os dados de produtividade (Ć”rea colhida e valor da produĆ§Ć£o), analisando a influĆŖncia das alteraƧƵes do clima atual na expansĆ£o da cana-de-aƧĆŗcar em MS, e o de comparar a produtividade da cana-de-aƧĆŗcar com a produtividade das culturas de soja e algodĆ£o

    A Multi-wavelength Study of the Host Environment of SMBHB 4C+37.11

    Get PDF
    4C+37.11, at z=0.055 shows two compact radio nuclei, imaged by VLBI at 7mas separation, making it the closest known resolved super-massive black hole binary (SMBHB). An important question is whether this unique object is young, caught on the way to a gravitational in-spiral and merger, or has `stalled' at 7pc. We describe new radio/optical/X-ray observations of the massive host and its surrounding X-ray halo. These data reveal X-ray/optical channels following the radio outflow and large scale edges in the X-ray halo. These structures are promising targets for further study which should elucidate their relationship to the unique SMBHB core.Comment: To appear in the Astrophysical Journa
