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
Nickel‐Catalyzed Electrooxidative C−H Amination: Support for Nickel(IV)
No full textAbstract Nickel‐catalyzed electrochemical C−H aminations were accomplished by chemo‐ and position‐selective C−H activation with ample scope. Detailed mechanistic studies highlighted a facile C−H cleavage with unique chemo‐selectivity, while cyclovoltammetric analysis provided support for a nickel(II/III/IV) manifold.Distinguished International Students Scholarship https://doi.org/10.13039/501100010893Deutsche Forschungsgemeinschaft https://doi.org/10.13039/501100001659Alexander von Humboldt-Stiftung https://doi.org/10.13039/10000515

Evolution of High‐Valent Nickela‐Electrocatalyzed C−H Activation: From Cross(‐Electrophile)‐Couplings to Electrooxidative C−H Transformations
No full textAbstract C−H activation has emerged as one of the most efficient tools for the formation of carbon–carbon and carbon–heteroatom bonds, avoiding the use of prefunctionalized materials. In spite of tremendous progress in the field, stoichiometric quantities of toxic and/or costly chemical redox reagents, such as silver(I) or copper(II) salts, are largely required for oxidative C−H activations. Recently, electrosynthesis has experienced a remarkable renaissance that enables the use of storable, safe and waste‐free electric current as a redox equivalent. While major recent momentum was gained in electrocatalyzed C−H activations by 4d and 5d metals, user‐friendly and inexpensive nickela‐electrocatalysis has until recently proven elusive for oxidative C−H activations. Herein, the early developments of nickela‐electrocatalyzed reductive cross‐electrophile couplings as well as net‐redox‐neutral cross‐couplings are first introduced. The focus of this Minireview is, however, the recent emergence of nickel‐catalyzed electrooxidative C−H activations until April 2020.Go electro! Nickela‐electrocatalyzed C−H activations have emerged as a sustainable platform in molecular sciences that avoid substrate prefunctionalizations and chemical oxidants by electricity. The robust nickela‐electrooxidations enabled C−C, C−O, and C−N formations with ample scope under exceedingly mild conditions. imageAlexander von Humboldt-Stiftung http://dx.doi.org/10.13039/100005156China Scholarship Council http://dx.doi.org/10.13039/501100004543DFG http://dx.doi.org/10.13039/50110000165

Rhinocricus guaritas Rodrigues, Ott & Rodrigues, 2012, sp. nov.
No full textRhinocricus guaritas sp. nov. (Figs. 16–22) Types. Holotype male from Caçapava do Sul, Rio Grande do Sul, Brazil, 29.X. 1975, P. C. Braum leg. (MCN 062). Paratype female, same data as the holotype (MCN 735). Etymology. The epithet refers to the name of a geological formation very characteristic and beautiful, found in the type locality. Diagnosis. Rhinocricus guaritas is close to Rhinocricus balanus Chamberlin, 1955 by the similar shape of the anterior gonopod sternite with narrowed base and evident coxites, but differs from R. balanus by the longer and broader median process of the sternite (Fig. 16).

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
