A marine systematic conservation plan for Rodrigues Island, Western Indian Ocean
No full textIncludes abstract.Includes bibliographical references (p. 53-59).In 2007 the local government of Rodrigues gazetted four marine reserves in the north of the island based on knowledge and insights from stakeholders, mainly from the fishing community. In order to verify the stakeholder-based design, a marine reserve network was designed using Marxan, a systematic conservation planning programme
Measurement of the ratio of prompt χ c to J / ψ production in pp collisions at √s = 7 TeV
No full textThe prompt production of charmonium χ c and J / ψ states is studied in proton-proton collisions at a centre-of-mass energy of √s = 7 TeV at the Large Hadron Collider. The χ c and J / ψ mesons are identified through their decays χ c → J / ψ γ and J / ψ → μ + μ - using 36 pb - 1 of data collected by the LHCb detector in 2010. The ratio of the prompt production cross-sections for χ c and J / ψ, σ (χ c → J / ψ γ) / σ (J / ψ), is determined as a function of the J / ψ transverse momentum in the range 2 < p T J / ψ < 15 GeV / c. The results are in excellent agreement with next-to-leading order non-relativistic expectations and show a significant discrepancy compared with the colour singlet model prediction at leading order, especially in the low p T J / ψ region

On Rastall gravity formulation as a and a theory
No full textRastall introduced a stress-energy tensor whose divergence is proportional to
the gradient of the Ricci scalar. This proposal leads to a change in the form
of the field equations of General Relativity, but it preserves the number of
degrees of freedom. Rastall's field equations can be either interpreted as GR
with a redefined SET, or it can imply different physical consequences inside
the matter sector. We investigate limits under which the Rastall field
equations can be directly derived from an action, in particular from two
-gravity extensions: and . We show that there
are similarities between these theories, but the Rastall SET cannot be fully
recovered from them, apart from certain particular cases here discussed. It is
remarkable that a simple, covariant and invertible redefinition of the SET, as
the one proposed by Rastall, is hard to be directly implemented in the action.Comment: 11 pages, accepted for publication in the European Physical Journal

Rodrigues parameters on dual hyperbolic unit sphere H20
No full textRodrigues parameters depend on the tangent of the half rotation angle in Euclidean space but in Dual space, dual Rodrigues parameters contain both rotation angle and distance corresponding the shortest distance between the straight lines in R-3. In this paper, we give Cayley's formula for the dual hyperbolic spherical motion and explain 3x3 type L-Dual skew symmetric matrices by using properties of this formula. Then, we obtain Rodrigues parameters of dual Hyperbolic unit sphere and show that Rodrigues parameters contain the hyperbolic rotation angle which is being between timelike lines and distance which is the minimal Lorentzian distance between the timelike lines of R-1(3)TUBITAK (The Scientific and Technological Research Council of Turkey)Turkiye Bilimsel ve Teknolojik Arastirma Kurumu (TUBITAK)The first author would like to thank TUBITAK (The Scientific and Technological Research Council of Turkey) for their financial supports during her PhD studies

Nelson Rodrigues : a mulher em tres planos
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina. Centro de Comunicação e ExpressãoO presente trabalho propõe uma re-leitura da obra teatral de Nelson Rodrigues, enfocando a "mulher" como elemento-chave de suas peças. A notória relevância atribuída pelo autor às personagens femininas, fazendo-as protagonistas da maioria de suas peças. Trata-se de uma visão nova (para a época) da sensibilidade feminina, num tratamento diferenciado da mulher, com suas mazelas e frustrações. A mulher tripartida interiormente, oscilando entre os planos da realidade, memória e alucinação, de acordo com os caminhos e descaminhos do desejo, à mercê das pressões sociais e familiares - é a representante do universo feminino da dramaturgia rodriguiana. Foram destacadas três personagens para um estudo mais detalhado. Das estruturas e linguagem da obra do autor foram extraídas as bases constitutivas dessas personagens. Três momentos distintos na criação do teatro do autor; três atos em cada uma das peças (a exceção de uma); três planos no palco de vestido de noiva e na divisão interna da complexa alma feminina. Uma proposta dramatúrgica voltada para os motivos intrínsecos da existência, como o amor, a morte, o desejo, o ódio e todas as situações limítrofes
