This article deals with the encounters between a traditional Korean rural and island population and western military forces when the British navy occupied Geomundo, an archipelago known to them as Port Hamilton, for 22 months between 1885 and 1887. The paper first outlines the sometimes painful process of East Asian countries being opened up to trade and outside influences in the 19th century, a process sometimes urged upon them by naval weapons in this era of gunboat diplomacy. This provides the setting for the Port Hamilton Affair itself when in preparation for possible war with Russia, a British naval squadron steamed into Port Hamilton and took it without reference to the local people or their national government. After brief reference to the political consequences of this action, the focus is then on what the records from the occupation and earlier investigations by the British, who had long coveted the islands’ strategic harbour, reveal about the life of the islanders. The article considers both their traditional life, from a time rather before western travel accounts were written about the Korean mainland, and how the islanders fared under the British.

The Keokuk & Hamilton Bridge is one of three remaining in Iowa that were designed by Ralph Modjeski, one of this country's premier early 20th century bridge engineers. The eleven-span, double-deck steel superstructure was built in 1915-1916 on piers retained from an earlier (1869-1871) structure, to meet greater loading requirements from railroads that operated across the Mississippi at this point.

We study congruences in the coefficients of modular and other automorphic forms. Ramanujan famously found congruences for the partition function like p(5n+4) = 0 mod 5. For a wide class of modular forms, we classify the primes for which there can be analogous congruences in the coefficients of the Fourier expansion. We have several applications. We describe the Ramanujan congruences in the counting functions for overparitions, overpartition pairs, crank differences, and Andrews' two-coloured generalized Frobenius partitions. We also study Ramanujan congruences in the Fourier coefficients of certain ratios of Eisenstein series. We also determine the exact number of holomorphic modular forms with Ramanujan congruences when the weight is large enough. In a chapter based on joint work with Olav Richter, we study Ramanujan congruences in the coefficients of Jacobi forms and Siegel modular forms of degree two. Finally, the last chapter contains a completely unrelated result about harmonic weak Maass forms.

The industrial effluents are one of the main sources of water pollution. For an appropriate characterization and control of their discharges, the most efficient strategy is the integrated use of chemical, physical and ecotoxicological analyses. The aims of this study were to asses the efficiency of the treatment plant of a textile industry performing acute toxicity tests and physical-chemical analyses of the effluents before and after the treatment, besides evaluate the toxicity of the effluents of the Treatment System of Liquids Effluents (Sistema de Tratamento de Efluentes Líquidos - SITEL) of Distrito Industrial de Natal (DIN) and some of their physical-chemical variables. The species used in the ecotoxicological tests was the fish Danio rerio. The results showed that the treatment plant reduced significantly (around 50%) the toxicity of the raw textile effluent in only three of the seven tests but, in general, it promoted the reduction of the physical-chemical parameters analyzed. The toxicity and the physical-chemical factors of the effluents of SITEL of DIN varied among the tests and show the importance of monitoring their discharges in the Potengi river, one of the most important rivers of the Rio Grande do Norte state

The objectives of this research were to investigate the agrotoxic most used in the Gramorezinho region in the green belt of Natal, and to evaluate the acute toxicity of these, based on the LC50-48h values estimated in tests for Danio rerio, internationally used as test organism. The acute toxicity tests were performed under laboratory conditions, according to standardized methods (ABNT/NBR/15088/04) for this species. The LC50-48h estimated to Tamaron BR was 352.89 mg.L-1, which characterizes that as practically non-toxic, according to toxicological classes cited by Zucker. For Decis 25EC, the LC50-48h estimated was 0.0004156 mg.L-1 (4.156 X 10-4 mg.L-1), which classifies it as highly toxic to this species

El cálculo vectorial apareció en el siglo XIX. Hay operaciones entre vectores tales como el producto escalar que se puede ampliar sin dificultad de espacios de dimensión dos a espacios de dimensión tres y superior. Sin embargo, la ampliación del producto vectorial de vectores de dimensión dos a vectores tridimensionales tuvo serias dificultades. El conocimiento de los pasos lógicos que tuvieron que dar Hamilton y Grassmann para sentar las bases del calculo vectorial en de gran importancia pedagógica para profundizar en el concepto de operación.

Introduction: Idiopathic Pulmonary Hemosiderosis (IPH) is a rare cause of alveolar hemorrhage, which is seen primarily in childhood. Celiac disease is defined as a chronic, immune-mediated enteropathy of the small intestine, caused by exposure to dietary gluten in genetically pre-disposed individuals. Association of IPH and celiac disease is known as Lane Hamilton syndrome. There are limited number of case reports of this syndrome in literature. Case Presentation: Although there were no growth and developmental delay and gastrointestinal symptoms like chronic diarrhea, chronic constipation, vomiting, abdominal bloating and pain in the two patients with IPH, they were diagnosed with Lane Hamilton Syndrome. After initiation of gluten-free diet, their IPH symptoms disappeared and hemoglobin levels were observed to return to normal. Conclusions: Even if there were no gastrointestinal symptoms in a patient with IPH, celiac disease should be investigated. These patients may benefit from gluten free diet and IPH symptoms may disappear.

A doença cardiovascular (DCV) é a maior causa de mortes no Brasil, causada por duas das comorbidades mais incidentes, Hipertensão Arterial Sistêmica (HAS) e Diabetes Mellitus (DM), sendo o número estimado de brasileiros portadores de ambas 23.000.000. A HAS é um grave problema de saúde pública no Brasil e no mundo, sendo a mais frequente das doenças cardiovasculares, além de ser o principal fator de risco para acidente vascular cerebral (AVC), infarto agudo do miocárdio (IAM) e doença renal crônica (DRC). O diabetes e suas repercussões podem gerar neuropatias e risco de amputações, especialmente, em membros inferiores. Um adequado controle dos níveis pressóricos, seja profilaticamente, seja já na fase de tratamento, exige mudanças no estilo de vida, alimentação adequada, controle do peso, prática regular de atividade física. Pensando nisso, foi realizada a intervenção nessa ação programática nas pessoas com hipertensão e/ou diabetes da Unidade Básica de Saúde (UBS) Dr° Hamilton Cidade, município de Rio Preto da Eva - AM, durante 12 semanas, com o objetivo de melhorar a atenção aos adultos portadores de Hipertensão Arterial Sistêmica e/ou Diabetes Mellitus. Foram identificados 632 pessoas com hipertensão e 156 com diabetes na comunidade, dos quais 535 com hipertensão e 145 com diabetes foram contatados e sujeitos do estudo, perfazendo uma porcentagem de, respectivamente, 83,1% e 92,9% de cobertura de atenção a esse grupo de usuários da área de abrangência. Os motivos que levaram aos excelentes percentuais de cobertura foram a seriedade e presteza da equipe, o envolvimento e dedicação de cada um para que pudéssemos alcançar esse resultado com a população. As ações que facilitaram a melhoria desse indicador foram visita domiciliar, buscas ativas, palestras na recepção e para a comunidade. Os usuários receberam avaliação clínica, orientação nutricional, sobre atividade física, tabagismo e foi realizada estratificação de risco. Em geral, o projeto proporcionou uma grande melhoria tanto no atendimento ao doente, quanto nas atividades desenvolvidas na UBS e na relação interpessoal dos seus funcionários.

O hábito de fumar antes disseminado como ato de prazer, tornou-se questão de Saúde Pública. Apesar de serem amplamente conhecidos os prejuízos do fumo à saúde, o mesmo persiste como uma das principais causas evitáveis de morte no mundo. O Programa Nacional de Controle de Tabaco (PNCT) tem o intuito de reduzir a prevalência de fumantes e a morbimortalidade das doenças tabaco relacionadas, pautado em diversas estratégias, como a promoção e apoio à cessação de fumar. O trabalho tem como objetivo elaborar um plano de ação para prevenção e redução da prevalência de fumantes e a consequente morbimortalidade relacionada ao consumo de derivados do tabaco na população assistida pela ESF Hamilton de Mello no município de Rio Preto/MG. A partir da realização do diagnóstico de estimativa rápida, em 2014, foram levantados alguns problemas na Unidade Básica de Saúde (UBS) Hamilton Mello em Rio Preto, com priorização da alta prevalência de fumantes local. Diante deste quadro, foi elaborado um plano de ação, como modelo piloto, nesta UBS, com o objetivo de reduzir o número de fumantes e melhorar a qualidade de vida dos mesmos com a formação de um grupo antitabagismo. Para o embasamento teórico do plano de ação foram resgatados artigos em bases de registro de bibliografias eletrônicas Literatura Latino Americana e do Caribe em Ciências da Saúde (LILACS), Medical Literature Analysis and Retrieval System Online (MEDLINE), e Biblioteca digital Scientific Eletronic Library On-line (SciELO), no período de 2004 a 2014. Para tal pesquisa foram utilizados os seguintes descritores: Tabagismo; Estratégia Saúde da Família; Saúde Pública; Educação Continuada, Atenção Primária à Saúde, para fundamentação teórica. Para a elaboração do plano de intervenção foi escolhido o método do Planejamento Estratégico Situacional (PES). A implantação do Grupo Antitabagismo é uma medida eficaz na diminuição do número de usuários crônicos do tabaco, possibilita uma abordagem coletiva, e concomitantemente valoriza as necessidades individuais, além de facilitar a observação dos pontos favorecedores ao abandono do tratamento. Constitui uma intervenção que frisa o papel da Atenção Primária dentro da Saúde Pública ao promover ações antifumo de acordo com medidas do PNCT.
