Analysis and design of a flat central finned-tube radiator

Computer program based on fixed conductance parameter yields minimum weight design. Second program employs variable conductance parameter and variable ratio of fin length to tube outside radius, and is used for radiator designs with geometric limitations. Major outputs of the two programs are given

Oblivion: Mitigating Privacy Leaks by Controlling the Discoverability of Online Information

Search engines are the prevalently used tools to collect information about individuals on the Internet. Search results typically comprise a variety of sources that contain personal information -- either intentionally released by the person herself, or unintentionally leaked or published by third parties, often with detrimental effects on the individual's privacy. To grant individuals the ability to regain control over their disseminated personal information, the European Court of Justice recently ruled that EU citizens have a right to be forgotten in the sense that indexing systems, must offer them technical means to request removal of links from search results that point to sources violating their data protection rights. As of now, these technical means consist of a web form that requires a user to manually identify all relevant links upfront and to insert them into the web form, followed by a manual evaluation by employees of the indexing system to assess if the request is eligible and lawful. We propose a universal framework Oblivion to support the automation of the right to be forgotten in a scalable, provable and privacy-preserving manner. First, Oblivion enables a user to automatically find and tag her disseminated personal information using natural language processing and image recognition techniques and file a request in a privacy-preserving manner. Second, Oblivion provides indexing systems with an automated and provable eligibility mechanism, asserting that the author of a request is indeed affected by an online resource. The automated ligibility proof ensures censorship-resistance so that only legitimately affected individuals can request the removal of corresponding links from search results. We have conducted comprehensive evaluations, showing that Oblivion is capable of handling 278 removal requests per second, and is hence suitable for large-scale deployment

Efeito da adubação e calagem na quantidade de ectomicorrizas em serapilheira de Pinus taeda em Jaguariaíva, PR.

Resumo

Fungos endofíticos associados a acículas de Pinus taeda.

O presente trabalho objetivou estudar os fungos endofíticos em acículas de árvores jovens de Pinus taeda L. e avaliar o efeito da posição de coleta na árvore. As amostras foram coletadas em duas alturas (30-50 cm e 100-130 cm acima do solo) e nas quatro posições cardeais (norte, sul, leste e oeste), em plantas com 18 meses de idade, localizadas em Colombo, PR, Brasil. As acículas foram submetidas a assepsia e fragmentos com 10 mm de comprimento foram plaqueados em meio BDA e incubados a 28 °C, sob fotofase de 12 h, por 15 dias. Para a identificação, as estruturas reprodutivas dos fungos foram produzidas pelo método do microcultivo. Foram isolados e identificados dezessete gêneros: Alternaria, Aspergillus, Cladosporium, Colletotrichum, Coniothyrium, Diplodia, Drechslera, Hansfordia, Monocillium, Nodulisporium, Panidio, Papulaspora, Pestalotiopsis, Phialophora, Pithomyces, Rhizoctonia e Xylaria Alguns morfotipos sem identificação foram Mycelia sterilia e fungos demaciáceos. O número de isolados da altura 30-50 cm foi significativamente maior que na outra altura. Não foi observada diferença significativa no número de isolados entre as posições cardeais de uma mesma altura. Diferenças significativas foram observadas entre os gêneros isolados e Xylaria foi o gênero mais frequente

The Territorial Agenda 2030: Towards a common language? A review of a conceptual framework

The Territorial Agenda 2030 aims to provide multi-level strategic orientation to increase cohesion and overcome the 21st century pressing challenges. In multilingual contexts, the ideas and concepts communicated in such agendas must be clear and well-defined. In our study, we conducted a content analysis of the concepts of environment, inequality, justice, sustainability, territory and transition in contrast with former versions of this agenda. We found that, since 1983, the Territorial Agenda conceptual framework changed significantly in its meaning and semantic universe of reference.info:eu-repo/semantics/publishedVersio
