Plantas do gênero Arachis são conhecidas da humanidade há cerca de 8 mil anos. O termo amendoim é originário de mãdu?bi, da língua tupi. As espécies forrageiras são comumente chamadas de amendoim forrageiro ou até grama amendoim no Brasil. A espécie Arachis pintoi Krapovickas & Gregory, exclusivamente forrageira, vem sendo cada vez mais usada para pastejo de animais devido à quantidade de proteínas e biomassa produzida, além do uso na jardinagem e paisagismo em áreas urbanas e rurais. Essa preferência pela espécie baseia-se em longo histórico de sucesso em outros países para a finalidade a que se destina. Outras espécies encontradas nesse gênero e utilizadas em programas de melhoramento genético de amendoim forrageiro para a produção de proteína a baixo custo são Arachis repens Handro, Arachis glabrata Benth., Arachis valsii Miotto, Arachis appressipila Krapov & W. C. Greg. e Arachis helodes Mart. ex Krapov. & Rigoni. Algumas doenças fúngicas afetam A. pintoi quando este se encontra estabelecido no campo ou em viveiro, casas de vegetação ou telado. No entanto, fungos que ocorrem nas sementes têm importante papel na disseminação de doença a longa distância e no estabelecimento de plantas de amendoim forrageiro no campo seja para multiplicação ou para uso definitivo. O conhecimento da diversidade de fungos fitopatogênicos e saprófitas que ocorrem em Arachis spp. é de fundamental relevância para os trabalhos de diagnósticos, para a emissão de certificados fitossanitários de origem, certificados fitossanitários, ações de defesa vegetal, segurança no trabalho e para o controle de doenças. Desse modo, foi elaborado este Manual que, além de ser um guia ilustrado para a identificação de doenças, também traz informações de como isolar e caracterizar taxonomicamente os fungos associados ao amendoim forrageiro. Esta publicação é destinada aos produtores, estudantes, professores, pesquisadores, técnicos e todos aqueles que se interessam pela cultura do amendoim forrageiro nos campos e nas cidades, em atividades produtivas, educacionais e de extensão.

Historical Annapolis Foundation (HAF) conducted terrestrial archaeological investigations at site 18AP21 in the city of Annapolis, Maryland. Excavations were carried out at this National Register site ostensibly as a Phase II project to evaluate the site and assess the need for further work. The site is at 99 Main Street in the center of downtown Annapolis, near the Annapolis waterfront. The project was carried out as part of the advanced work for the Annapolis History Center project, to be built in the adjoining buildings of 99 Main and 196 Green Streets. The buildings are the property of the Historic Annapolis Foundation and located in Maryland Research Unit 7. The excavations were undertaken by HAF, and funded by HAFF. The work was conducted for HAF and MHT, who holds an archaeological easement on the property. This preliminary phase of work included stratigraphic excavation of two testpit units. These two units revealed that the site of the existing 99 Main Street building was the location of three previous constructions. The current building at 99 Main Street, built in 1791, was preceded by an earlier brick dwelling, evidenced by a stout pier of bricks, which was attached to a wooden-sided structure that stood on a foundation of brick and stone. Ceramics indicate that these buildings date to the early-middle of the 18th century. A third structure of post-in-ground construction, evidenced by recovery of burned posts and wood fragments, likely existed prior to these, but evidence was scant. These excavations reveal that the site of 18AP21 holds potential for understanding Annapolis's early cultural developments, especially in the area of initial settlement and the origins of waterfront commerce. The assemblage of artifacts recovered includes a broad sample of common 18th century pottery such as creamware and Chinese export porcelain, and also includes some early colonial types such as tin-glazed earthenware and various red-bodied slipwares. The excavations do not provide conclusive evidence of the construction sequence. Consultation with MHT representatives indicates that further work at the site will likely be needed before modifications to the floor of the building can progress.

The parallelization of existing/industrial electromagnetic software using the bulk synchronous parallel (BSP) computation model is presented. The software employs the finite element method with a preconditioned conjugate gradient-type solution for the resulting linear systems of equations. A geometric mesh-partitioning approach is applied within the BSP framework for the assembly and solution phases of the finite element computation. This is combined with a nongeometric, data-driven parallel quadrature procedure for the evaluation of right-hand-side terms in applications involving coil fields. A similar parallel decomposition is applied to the parallel calculation of electron beam trajectories required for the design of tube devices. The BSP parallelization approach adopted is fully portable, conceptually simple, and cost-effective, and it can be applied to a wide range of finite element applications not necessarily related to electromagnetics.

In this study, a simplified Acoustic Emission (AE) equipment, in essence an AE signal conditioner and a USB (Universal Serial Bus) data acquisition system, is used to study what happens in paper structures during mechanical loading. By the use of such equipment, some parameters that can be extracted are e.g. the stress and strain at onset of AE, the stress and strain at the onset of rapid AE defined as some numerical factor (larger then one) times the initial emission rate, the emission rate at the first stage of loading and the stress and strain at final failure i.e. when the specimen loses its load carrying ability.In this study however, the interest is focused on one particular parameter i.e. the elastic strain energy density W c at onset of AE. This is a parameter with a clear physical meaning and in this study, the correlation between this parameter and a fracture toughness measure, is investigated.The conclusion is that when nine different paper materials (with a large span regarding properties) are considered, there is a correlation (however not linear) between these two parameters.
