DESEMPENHO FOTOSSINTÉTICO DE PLANTAS DE Jatropha curcas L. CULTIVADAS NO ESTADO DO ESPÍRITO SANTO

RESUMO Neste trabalho foram utilizadas plantas de pinhão manso (Jatropha curcas L.), no mesmo estádio de desenvolvimento e sob iguais condições de manejo cultural, cultivadas em duas fazendas comerciais: uma na região norte, litorânea (Pontal do Ipiranga, Linhares) e a outra na região noroeste, montanhosa (Itarana) do Estado do Espírito Santo com o objetivo de avaliar o desempenho fotossintético in situ. Foram realizadas medidas durante um ano (maio/2010 a maio/2011) do crescimento, índice de clorofila, trocas gasosas, fluorescência transiente e modulada da clorofila a. Análises in vitro dos teores de clorofila e da atividade de enzimas antioxidantes também foram realizadas. Os resultados obtidos mostraram que as plantas cultivadas no interior do estado do Espírito Santo apresentaram maior crescimento em altura e maior eficiência real do uso da água (A/E). As plantas desta região também apresentaram menor atividade antioxidante (SOD, CAT e APX) em resposta a uma menor produção de espécies reativas de oxigênio (ROS). As plantas cultivadas no litoral, com solo de menor disponibilidade de nutrientes, apresentaram maiores teores de clorofila a e b, maiores taxas de fotossíntese líquida (A) e maiores índices de desempenho fotoquímico. Infere-se, portanto que as plantas de pinhão manso possuem estratégias adaptativas que lhes permitem viver em ambiente de condições adversas. Além disso, a fluorescência transiente da clorofila a mostrou-se eficiente para avaliar o desempenho fotossintético de plantas do pinhão manso cultivadas sob condições de estresse ambientais: hídrico, térmico e nutricional

Pubertal Delay. The challenge of a timely differential diagnosis between Congenital Hypogonadotropic Hypogonadism (CHH) and Constitutional Delay of Growth and Puberty (CDGP): a narrative review

Distinguishing between Constitutional Delay of Growth and Puberty (CDGP) and Congenital Hypogonadotropic Hypogonadism (CHH) may be challenging. CDGP and CHH appear to belong to the same clinical spectrum (with low sex hormones and low LH and FSH), although one is classically transient and known as a self-limited form of delayed puberty (CDGP) while the other is permanent (CHH). Thus, the clinical history and the outcomes of these two conditions require different approaches, and an adequate and timely management for the patients is mandatory. Since the initial presentation of CDGP and CHH is almost identical and given the similarities of CDGP and partial forms of CHH (i.e. patients with partial and early interrupted pubertal development) the scientific community has been struggling to find some diagnostic tests able to allow an accurate differential diagnosis between these two conditions in delayed puberty. In this review we provide an up to date insight on the tests available, their meanings and accuracy, as well as some clues to effectively differentiate between constitutional pubertal delay and pathologic CHH

Innovative hybrid and composite steel-concrete structural solutions for building in seismic area

The INNO-HYCO research project aims at defining innovative steel and reinforced concrete hybrid systems for construction of feasible and easy repairable buildings in seismic zones, able to fully exploit the stiffness of concrete components and the ductility, dissipation capacity, and replaceability of steel elements. Hybrid coupled shear walls (HCSW) and steel frames with reinforced concrete infill walls (SRCW) are considered. An innovative HCSW system is obtained through the connection of a reinforced concrete wall to side steel columns by means of replaceable steel links acting as dissipative elements. A capacity design procedure based on limit analysis is developed in order to enforce a suitable dissipative mechanism while limiting the wall damage. An innovative SRCW system is derived as an evolution of the system considered in Eurocode 8 through the adoption of solutions capable to overcome its drawbacks as observed in preliminary analyses. The infill walls are connected only at their corners to bearing plates to foster the formation of diagonal concrete struts. The dissipative elements are replaceable portions of the side columns that are not connected to the infill walls. A specific capacity design is developed to avoid the wall crushing. Experimental investigations on the two systems are used to validate the theoretical assumptions and to derive specific nonlinear models for the assessment of the designs based on the proposed procedures. Finally, the two innovative hybrid systems are used in the design of a realistic case study consisting in a 6-storey building in a medium-high seismic area

CALIFA, the Calar Alto Legacy Integral Field Area survey IV. Third public data release

This paper describes the Third Public Data Release (DR3) of the Calar Alto Legacy Integral Field Area (CALIFA) survey. Science-grade quality data for 667 galaxies are made public, including the 200 galaxies of the Second Public Data Release (DR2). Data were obtained with the integral-field spectrograph PMAS/PPak mounted on the 3.5m telescope at the Calar Alto Observatory. Three different spectral setups are available: i) a low-resolution V500 setup covering the wavelength range 3745–7500 Å (4240-7140 Å unvignetted) with a spectral resolution of 6.0 Å (FWHM) for 646 galaxies, ii) a medium-resolution V1200 setup covering the wavelength range 3650–4840 Å (3650-4620 Å unvignetted) with a spectral resolution of 2.3 Å (FWHM) for 484 galaxies, and iii) the combination of the cubes from both setups (called COMBO) with a spectral resolution of 6.0 Å and a wavelength range between 3700-7500 Å (3700-7140 Å unvignetted) for 446 galaxies. The Main Sample, selected and observed according to the CALIFA survey strategy covers a redshift range between 0.005 and 0.03, spans the color-magnitude diagram and probes a wide range of stellar masses, ionization conditions, and morphological types. The Extension Sample covers several types of galaxies that are rare in the overall galaxy population and are therefore not numerous or absent in the CALIFA Main Sample. All the cubes in the data release were processed using the latest pipeline, which includes improved versions of the calibration frames and an even further improved image reconstruction quality. In total, the third data release contains 1576 datacubes, including ∼1.5 million independent spectra. It is available at http://califa.caha.es/DR3.CALIFA is the first legacy survey being performed at Calar Alto.

VizieR Online Data Catalog: CALIFA Survey DR3 list of galaxies (Sanchez+, 2016)

There are two fundamentally different samples of galaxies in the CALIFA DR3: (1) Galaxies that were targeted because they were part of the CALIFA mother sample that is fully described and characterized in Walcher et al. (2014A&A...569A...1W). This sample is called the CALIFA Main Sample. (2) The CALIFA Extension Sample, which is a heterogeneous set of galaxies observed for various reasons as part of different ancillary science projects within the CALIFA collaboration. The DR3 release is the combination of the Main Sample and the Extension Sample. (1 data file)
