Coordinación de actividades transversales del módulo básico de los Grados en Biología y Ciencias del Mar

La coordinación de las actividades de un curso pretende mejorar la calidad de la docencia. En este sentido la calidad tiene diferentes matices y aspectos como la cohesión de los cursos, la gestión de la planificación temporal, y la coordinación de las competencias transversales, así como la solución a las incidencias que aparecen a lo largo del curso. Una vez en marcha el curso, a partir de los planes elaborados inicialmente y con la aportación del alumnado en las respectivas reuniones de coordinación, tanto del presente curso como de los anteriores, se ha creado una dinámica de mejora de la planificación coordinada que afecta a todas las competencias del ciclo básico. Se han detectado puntos críticos en la gestión de los recursos que pueden ser limitados, como laboratorios, aulas de ordenadores, la distribución de los tipos de actividades en cada semana, o incluso el propio horario que no es ilimitado. Estos aspectos introducen las principales restricciones cuando se trata de evaluar los esfuerzos de carga de créditos ECTS semanales. La gestión de todos estos aspectos ayudará en el proceso continuo de mejora de la calidad de la docencia en el segundo semestre del ciclo básico de los Grados en Biología y en Ciencias del Mar

Biomassa de genótipos de Brachiaria brizantha em função da aplicação de fósforo.

RESUMO - A forrageira Brachiaria brizantha é amplamente cultivada no Brasil, em função de sua adaptabilidade a solos de baixa fertilidade natural. No entanto, o fósforo tem sido limitante para sua produção no Cerrado. Assim, este trabalho teve objetivo de avaliar produção de biomassa em função do fornecimento de fósforo em diferentes cultivares de B. brizantha. O delineamento experimental utilizado foi inteiramente casualizado com parcelas subdivididas, onde os oito tratamentos consistiram de cinco cultivares (Arapoty, Capiporã, Marandu, Piatã e Xaraés) e três acessos do banco de germoplasma Embrapa CNPGC (B5, B10 e B12), as subparcelas foram à aplicação ou não de fósforo. As plantas foram cultivadas sob solo originalmente com 4,1 mg dm-³ de fósforo, em casa de vegetação. Avaliou-se a massa fresca (MFR) e seca (MSR) da raiz e massa fresca (MFPA) e seca (MSPA) da parte aérea. Os dados foram submetidos ao teste de Doon ao nível de 5% de probabilidade. Evidenciou-se que para a variável MFR as cultivares Arapoty, Capiporã, Piatã e Xaraés obtiveram resposta significativa ao incremento de fósforo. No entanto, para a variável MSR apenas a cultivar Arapoty obteve resposta significativa. Para as variáveis MFPA e MSPA todas as cultivares apresentaram diferença significativa ao tratamento com fósforo.Resumo expnadido

Teores de nitrogênio em genótipos de Brachiaria brizantha em função da aplicação de fósforo.

RESUMO - As espécies de Brachiaria brizantha são cultivadas em larga escala no Cerrado por suas características de adaptação a solos com baixa fertilidade natural. No entanto, a disponibilidade de fósforo no solo tem alterado a concentração do teor de nitrogênio encontrado nas plantas. Desta forma este trabalho teve o objetivo de avaliar a concentração de nitrogênio em Brachiaria brizantha com base na presença ou ausência da aplicação de fósforo. Foi utilizado um solo com baixa disponibilidade de fósforo. O delineamento experimental utilizado foi o inteiramente casualizado, em um esquema fatorial 2 x 8, sendo dois níveis de P (aplicação de fósforo - 1,2 g de P por vaso, e sem aplicação de fósforo) e oito materiais genéticos (cinco variedades de B. brizantha - Marandú, Piatã, Capiporã, Xaraés e Arapoty, e três genótipos do Banco de Germoplasma do CNPGC/Embrapa - identificados como genótipos B5, B10 e B12. Os dados foram submetidos à análise de variância e ao teste de Tukey, ao nível de 5% de significância. O teor médio de nitrogênio foliar foi significativamente maior em plantas que receberam a aplicação de fósforo.A aplicação de fósforo promoveu diferentes respostas entre as cultivares e genótipos estudados.Resumo expandido

Beam Energy and Centrality Dependence of Direct-Photon Emission from Ultrarelativistic Heavy-Ion Collisions.

The PHENIX collaboration presents first measurements of low-momentum (0.41  GeV/c) direct-photon yield dN_{γ}^{dir}/dη is a smooth function of dN_{ch}/dη and can be well described as proportional to (dN_{ch}/dη)^{α} with α≈1.25. This scaling behavior holds for a wide range of beam energies at the Relativistic Heavy Ion Collider and the Large Hadron Collider, for centrality selected samples, as well as for different A+A collision systems. At a given beam energy, the scaling also holds for high p_{T} (>5  GeV/c), but when results from different collision energies are compared, an additional sqrt[s_{NN}]-dependent multiplicative factor is needed to describe the integrated-direct-photon yield

Cold Nuclear Matter Effects on J/psi Yields as a Function of Rapidity and Nuclear Geometry in Deuteron-Gold Collisions at sqrt(s_NN) = 200 GeV

We present measurements of J/psi yields in d+Au collisions at sqrt(s_NN) = 200 GeV recorded by the PHENIX experiment and compare with yields in p+p collisions at the same energy per nucleon-nucleon collision. The measurements cover a large kinematic range in J/psi rapidity (-2.2 < y < 2.4) with high statistical precision and are compared with two theoretical models: one with nuclear shadowing combined with final state breakup and one with coherent gluon saturation effects. To remove model dependent systematic uncertainties we also compare the data to a simple geometric model. We find that calculations where the nuclear modification is linear or exponential in the density weighted longitudinal thickness are difficult to reconcile with the forward rapidity data.Comment: 449 authors from 66 institutions, 6 pages, 3 figures.

Upsilon (1S+2S+3S) production in d+Au and p+p collisions at sqrt(s_NN)=200 GeV and cold-nuclear matter effects

The three Upsilon states, Upsilon(1S+2S+3S), are measured in d+Au and p+p collisions at sqrt(s_NN)=200 GeV and rapidities 1.2<|y|<2.2 by the PHENIX experiment at the Relativistic Heavy-Ion Collider. Cross sections for the inclusive Upsilon(1S+2S+3S) production are obtained. The inclusive yields per binary collision for d+Au collisions relative to those in p+p collisions (R_dAu) are found to be 0.62 +/- 0.26 (stat) +/- 0.13 (syst) in the gold-going direction and 0.91 +/- 0.33 (stat) +/- 0.16 (syst) in the deuteron-going direction. The measured results are compared to a nuclear-shadowing model, EPS09 [JHEP 04, 065 (2009)], combined with a final-state breakup cross section, sigma_br, and compared to lower energy p+A results. We also compare the results to the PHENIX J/psi results [Phys. Rev. Lett. 107, 142301 (2011)]. The rapidity dependence of the observed Upsilon suppression is consistent with lower energy p+A measurements.Comment: 495 authors, 11 pages, 9 figures, 5 tables. Submitted to Phys. Rev. C.

Cross sections and double-helicity asymmetries of midrapidity inclusive charged hadrons in p+p collisions at sqrt(s)=62.4 GeV

Unpolarized cross sections and double-helicity asymmetries of single-inclusive positive and negative charged hadrons at midrapidity from p+p collisions at sqrt(s)=62.4 GeV are presented. The PHENIX measurements for 1.0 < p_T < 4.5 GeV/c are consistent with perturbative QCD calculations at next-to-leading order in the strong coupling constant, alpha_s. Resummed pQCD calculations including terms with next-to-leading-log accuracy, yielding reduced theoretical uncertainties, also agree with the data. The double-helicity asymmetry, sensitive at leading order to the gluon polarization in a momentum-fraction range of 0.05 ~< x_gluon ~< 0.2, is consistent with recent global parameterizations disfavoring large gluon polarization.Comment: PHENIX Collaboration. 447 authors, 12 pages, 5 figures, 5 tables.

Spectra and ratios of identified particles in Au+Au and d+Au collisions at sqrt(s_NN)=200 GeV

The transverse momentum (p_T) spectra and ratios of identified charged hadrons (\pi^+/-, K^+/-, p, p^bar) produced in sqrt(s_NN)=200 GeV Au+Au and d+Au collisions are reported in five different centrality classes for each collision species. The measurements of pions and protons are reported up to p_T=6 GeV/c (5 GeV/c), and the measurements of kaons are reported up to p_T=4 GeV/c (3.5 GeV/c) in Au+Au (d+Au) collisions. In the intermediate p_T region, between 2--5 GeV/c, a significant enhancement of baryon to meson ratios compared to those measured in p+p collisions is observed. This enhancement is present in both Au+Au and d+Au collisions, and increases as the collisions become more central. We compare a class of peripheral Au+Au collisions with a class of central d+Au collisions which have a comparable number of participating nucleons and binary nucleon-nucleon collisions. The p_T dependent particle ratios for these classes display a remarkable similarity, which is then discussed.Comment: 416 authors, 18 pages, 15 figures, 4 tables. Submitted to Phys. Rev. C.
