OMAE2004-51302 TEMPERATURE LIMITS FOR ASPHALT COATED FLOWLINES -A DESIGN APPROACH
ABSTRACT The 18" flowline from the Mikkel template in the North Sea was coated with asphalt enamel for corrosion protection and an external concrete coating for weight. The high internal temperature of 85 o C close to the template can give relative thermal movements between the outer concrete coating and the inner steel pipe. The case is considered to be similar to an adhesive joint between two tubular members. The strength approach is based on the analysis of the shear stress distribution in this "adhesive" joint. The material stiffness (shear modulus) of the asphalt was used to determine the upper temperature limit for the asphalt coating. The hotter part of the flowline had to be coated with polypropylene instead of asphalt
A propriedade sem registro : o contrato e aquisição da propriedade imóvel na perspectiva civil-contitucional
Orientador : Prof. Dr. Eroulths Cortiano JuniorTese (doutorado) - Universidade Federal do Paraná, Setor de Ciências Jurídicas, Programa de Pós-Graduação em Direito. Defesa: Curitiba, 12/08/2014Inclui referênciasResumo: Esta tese objetiva uma releitura da obrigatoriedade do registro nas aquisições da propriedade imóvel, a partir do reconhecimento do contrato como dotado de função social, que realiza, igualmente, a função social como liberdade de acesso aos bens. A propriedade imobiliária no Direito Civil brasileiro está qualificada como direito real, conforme o art. 1225, I, do Código Civil, e sua transferência negocial se orienta pelo sistema da separação parcial dos planos dos direitos obrigacionais e reais, o qual prevê a necessidade do contrato de transmissão (compra e venda, doação ou permuta) com posterior registro no Cartório Imobiliário, nos termos do art. 1245 e seguintes. A Constituição Federal de 1988 garante o direito de propriedade, que deve atender à sua função social, considerando-a como direito fundamental (art. 5.o, XXII e XXIII) e como princípio geral da ordem econômica (art. 170, II e III). A necessária interação entre o Direito Civil e a Constituição, sob a supremacia hierárquica desta, conduz a entender que o direito de propriedade atual, para além da literalidade do Código Civil, deve nortear-se pela sintonia entre ambos os diplomas legais, mas a partir da observação dos princípios e dos valores constitucionais. O Direito Civil-Constitucional surge, então, como uma opção de desenvolvimento do pensamento jurídico, que visa oferecer espaço de reflexão que supere a dogmática unicamente codificada, pois, com fundamento nos princípios e na axiologia constitucional, auxilia na ressignificação de institutos clássicos, como a propriedade e o contrato. O acesso à propriedade, então, pode ser considerado para além da letra da lei, o que permite relevar o registro, com a funcionalização do contrato que, a partir de sua teleologia, da solidariedade, da alteridade e da boa-fé, pode ser o elemento constitutivo da propriedade, com base no caso concreto. A aplicação direta e imediata da Constituição nas relações interprivadas favorece a ressignificação do contrato, que alçará significado de título suficiente para garantir o direito à propriedade (acesso). A complexidade e a pluralidade das relações sociais conduzem a uma transição do modelo abstrato e individualista da propriedade para o da propriedade concreta, que se constrói na funcionalização como liberdade(s) com vistas à realização das necessidade da pessoa concretamente considerada.Abstract: The aim of this thesis is to re-read the mandatory registration on acquisition of immovable property, from the social function of contract's recognition, which also performs its social function as freedom of access to assets. The immovable property in the Brazilian Civil Law is qualified as a real right, according to art. 1225, I, Civil Code, and its negotiating transferring is guided by the partial separation between obligations and real rights, which predicts the registration of transmission's contract (sale, donation or exchange) with the state registration authority, according to art. 1245 and on Civil Code. The 1988 Federal Constitution guarantees the right to property, which must meet its social function, considering it as a fundamental right (art. 5, XXII and XXIII) and as a general principle of economic order (art. 170, II and III). The necessary interaction between the civil law and the Constitution, under the hierarchical supremacy of this leads to understand that the current property law, beyond its literal meaning of the Civil Code, shall be guided by the line between the two enactments, but from the observation of constitutional principles and values.The Civil-constitutional Law arises, then, as an option for legal thinking development, which aims to provide a reflection space that overcomes the consolidated dogmatic, therefore, on the basis of principles and the constitutional axiology, assists in reframing classical institutes, as property and contract. The access to the property can then be considered beyond the letter of the law, which allows to release the register, with the functionalization's contract which, from its teleology, solidarity, alterity and good faith, may be the constituent element of the property, based on the case. The direct and immediate constitutional applying in privates relations cooperate to the contract redefinition, which obtain the sufficient title to guarantee the right to property (access). The complexity and plurality of social relations lead to a transition from abstract and individualistic model of property to concrete one which is constructed on functionalization as freedom (s) to intending to accomplish persons needs concretely considered
A phase I prospective, non-randomized trial of autologous dendritic cell-based cryoimmunotherapy in patients with metastatic castration-resistant prostate cancer
Metastatic castration-resistant prostate cancer (mCRPC) is an immunologically cold disease with dismal outcomes. Cryoablation destroys cancer tissue, releases tumor-associated antigens and creates a pro-inflammatory microenvironment, while dendritic cells (DCs) activate immune responses through processing of antigens. Immunotherapy combinations could enhance the anti-tumor efficacy. This open-label, single-arm, single-center phase I trial determined the safety and tolerability of combining cryoablation and autologous immature DC, without and with checkpoint inhibitors. Immune responses and clinical outcomes were evaluated. Patients with mCRPC, confirmed metastases and intact prostate gland were included. The first participants underwent prostate cryoablation with intratumoral injection of autologous DCs in a 3 + 3 design. In the second part, patients received cryoablation, the highest acceptable DC dose, and checkpoint inhibition with either ipilimumab or pembrolizumab. Sequentially collected information on adverse events, quality of life, blood values and images were analyzed by standard descriptive statistics. Neither dose-limiting toxicities nor adverse events > grade 3 were observed in the 18 participants. Results indicate antitumor activity through altered T cell receptor repertoires, and 33% durable (> 46 weeks) clinical benefit with median 40.7 months overall survival. Post-treatment pain and fatigue were associated with circulating tumor cell (CTC) presence at inclusion, while CTC responses correlated with clinical outcomes. This trial demonstrates that cryoimmunotherapy in mCRPC is safe and well tolerated, also for the highest DC dose (2.0 × 108) combined with checkpoint inhibitors. Further studies focusing on the biologic indications of antitumor activity and immune system activation could be considered through a phase II trial focusing on treatment responses and immunologic biomarkers.publishedVersio
An Experimental and Numerical Investigation of the Effect of Axial Thermal Gradients in Flexible Pipes
This paper discusses the structural challenges associated with high axial temperature gradients and the corresponding internal cross section forces. A representative flexible pipe section designed for high operational temperature has been subject to full scale testing with temperature profiles obtained by external heating and cooling. The test is providing detailed insight in onset and magnitude of relative layer movements and layer forces. As part of the full-scale testing, novel methods for temperature gradient testing of unbonded flexible pipes have been developed, along with layer force- and deflection-measurement techniques. The full-scale test set-up has been subject to numerous temperature cycles of various magnitudes, gradients, absolute temperatures, as well as tension cycling to investigate possible couplings to dynamics.
Extensive use of finite element analysis has efficiently supported test planning, instrumentation and execution, as well as enabling increased understanding of the structural interaction within the unbonded flexible pipe cross section. When exploiting the problem by finite element analysis, key inputs will be correct material models for the polymeric layers, and as-built dimensions/thicknesses. Finding the balance between reasonable simplification and model complexity is also a challenge, where access to high quality full-scale tests and dissected pipes coming back from operation provides good support for these decisions.
Considering the extensive full scale testing, supported by advanced finite element analysis, it is evident that increased attention will be needed to document reliable operation in the most demanding high temperature flexible pipe applications.acceptedVersio
