Genetic diversity and structure of Astrocaryum jauari (Mart.) palm in two Amazon river basins.

Astrocaryum jauari is a non-domesticated palm that is exploited by poachers. Our objective was to investigate the organization of the geneticdiversity and structure of three A. jauari populations. The study was carried out in the state of Amazonas, between the municipalities of Coari and Manaus. Nine microsatellite loci were used for the genetic analyses. High genetic variation was found, with a mean number of alleles per locus varying from 3.9 to 4.4. The average observed heterozygosity, varying from 0.71 to 0.78, was higher than expected. No spatial genetic structure was detected, since only one cluster was observed. Our results indicate a possible dispersion strategy and suggest that conservation measures of this species should focus mainly on the populations found at the end of the main river (Solimões) where most of the plant material originating from the headwaters of the tributaries of this river is concentrated

Implementação da Metodologia 5’S num Setor de Manutenção de uma Indústria Cerâmica

A necessidade de qualquer empresa se adaptar às condições de mercado constitui uma constante e, se adicionarmos o fator globalização, torna-se um imperativo. Face a esta situação, são muitas as empresas que começam a abandonar os métodos de gestão, ditos “tradicionais”, e começam a perseguir novas metodologias, com destaque para o Lean Manufacturing. Neste contexto, assumindo-se como uma das ferramentas elementares da filosofia Lean, a Metodologia 5’S apresenta como primordial objetivo a eliminação do “desperdício”, em paralelo com a criação de um ambiente de trabalho mais organizado, limpo e seguro, contribuindo desta forma, para a otimização dos processos operacionais de uma empresa. A origem do termo “5’S”, fica a dever-se à letra inicial “S” de cinco palavras japonesas que dão o nome a cada uma das etapas da própria metodologia. São elas: Seiri (Classificação e Separação), Seiton (Organização), Seiso (Limpeza), Seiketsu (Estandardização), Shitsuke (Autodisciplina). Neste trabalho, será analisada a capacidade da metodologia 5’S em eliminar o desperdício numa empresa do setor cerâmico tomada como referência, bem como a eficácia da mesma, no estabelecimento de um local de trabalho mais eficiente, confortável, e seguro para os trabalhadores.ABSTRACT: The companies must adapt to business requirements constantly, mainly if the Globalization would be considered as factor. That is why so many companies are starting to follow the Lean Manufacturing philosophy instead of Management traditional methods. Based on this scenario, the main purpose of 5S methodology, classified as one of the most important lean manufacturing tools, is eliminate wasting while provide the work environment clean, organized and safe, in that way, providing operational process improvements. The origin of 5S is regarding to initial letter "s" of five Japanese words which represents every single step of the methodology, which are: Seiri (Classification and Split), Seiton (Organization), Seiso (Cleaning), Seiketsu (Standard) and Shitsuke (Selfdiscipline). During this project, it is going to be analyzed how the 5S methodology can affect in the wasting elimination in a ceramic company taken as a reference, and its efficiency as well to stablish one work environment more efficient, comfortable and safe for employees
