Implantação do sistema kanban para elementos de fixação em maquinas de movimentação de terra

Always seeking the maximum profit under the reduced production time and lower number of failures, companies are increasingly evolving and going after continuous improvement in order to remain competitive in the market. Thus, increasingly there is investment in the management system Lean manufacturing. Lean system is very important, because through it, the maximum value is added in the final product. Being measured by the efficiency and reducing failures to zero. In the studied company, Lean manufacturing system came into effect through the kanban system for purchasing, control and distribution of bulk material used in the assembly of the final product, which are earth-moving machines. It is very important to check the great change made in the company with the implementation of kanban. All inventory management becomes visual, elements are arranged in an organized manner, with addresses in structures, calculated in special boxes and finally, assemblers have the guarantee of an item supply, with the distribution cars located on their assembly area. This study participates effectively assuring the supply. Avoiding any failure on the lack of material, non-compliance of delivery times to the customer and maintenance of over-stock or obsolete inventory, in which case both cause financial loss to the company

A recepção crítica das peças de Victor Hugo na França e no Brasil

Les premières pièces de Victor Hugo ont été les responsables d'une véritable révolution dans l'histoire de las Litterature Française, mais elles n'ont pas eu une acceptation immédiate de la part de la critique, qui s'est partagée entre les partidaires des romantiques et, par conséquent, de nouvelles idées diffusées par le Cénacle et les classiques, les adversaires des jeunes écrivains qui ont embrassé les concepts hugoliens, Au Brésil, la réacrion a été postérieure, mais identique. Qualqu'on ne trouve pas dans les journaux des discussions à propos de la nouvelle école, des nouvelles idées ont été, au début, rejetées par les intellectuels brésiliens et, quelque temps plus tard, adoptées par les écrivains désirant créer un théâtre national basé sur les prinipes défendus par Victor Hugo, le porte-parole du mouvement romantique.

Absentismo laboral por patología odontológica y médica en una industria de gran porte del sector mecánico y mueblero

Introduction: The current Brazilian legislation states that health services must be performed by the Specialized Service of Safety Engineering and Labor Medicine (SESMT). Objective: To analyze the dental and medical reasons for absenteeism, checking the interference of factors such as age, gender and position of the worker, and most of the reasons that led the employee to miss work. Material and methods: The research appears as a descriptive study with a quantitative approach. The dental and medical certificates and statements of attendance were analyzed, duly approved, lodged in a acrylic industry in the city of Araçatuba-SP, from January to July 2011. Results: Of the total number of certificates (n = 1841), only 103 (5.6%) were for dental reasons. Predominance of the age group of 20-29 years, males and with non-administrative function. The reasons most dental and medical certificates stated that led the workers to miss working days were "inclusive and impacted teeth" and "diarrhea and gastroenteritis of presumed infectious origin", respectively. As to factors related to absenteeism, there was a severity index of 2.83, 1.33 frequency and average duration of absences of 2.12. Conclusions: It is concluded that dental reasons had little weight on total absences due to illness that caused the temporary leave of the worker for a shorter period. The age and function variables influence the occurrence of work absenteeism.

A influência das variáveis do lixamento tubular na qualidade das peças de Eucalyptus grandis

In 2010, the Brazilian forest sector is represented by about 30,000 companies producing US$ 21 billion annually and account for approximately 5% of the gross domestic product (GDP) in the country. The sanding process is highly demanded in various stages of industrialization of the wood, when there is a need for a better quality surface finishing. The objective of this work was to analyze the influence of cutting speed and sandpaper granulometry on both the surface finishing of pieces of Eucalyptus grandis processed through tubular sanding and on the sanding efforts (force and power of sanding). Four cutting speeds were used (19.5, 22.7, 26 and 28.1 m/s), one advance speed (16 m/min) and three sets of sandpaper (80-100, 80-120 and 100-120) being one for chipping and another for finishing, respectively. A central data acquisition system was set up to capture the variables (cutting power, acoustic emission and vibration) in real time. The cutting force was obtained indirectly, through a frequency inverter. The roughness of the parts was measured by a roughness meter before and after sanding. The highest cutting speed used (28.1 m/s) consumed more power and generated more acoustic emission among the four speeds tested. Regarding the vibration, the lower cutting speed (19.5 m/ s) generated the highest vibration in the sander machine. It is concluded that the range of 100-120 sandpapers resulted in values of average roughness (Ra) lower than the other sets of sandpaper used, as it resulted in better surface finishing.

Previsão de demanda para peças de reposição de alto giro: aplicação de método descritivo simples comparado com o modelo suavização exponencial

O estudo de métodos de previsão de demandas é um conceito bastante popular, mas nem sempre seus resultados são facilmente aplicáveis nas organizações por várias limitações. O propósito deste artigo é apresentar um método simples e descritivo para a previsão de demanda para peças de reposição de alto giro e comparar os resultados com o modelo de suavização exponencial. Foi utilizado para isto, dados reais de consumo de uma empresa de geração de energia em dois anos com a mesma condição de contorno, e estabeleceu-se o ano de 2012 com a série de aplicação dos métodos e a série de 2013 com a série de validação dos resultados e em todas as amostras tomadas observou-se um menor erro quadrático RMSE, a favor do método descritivo simplificado. Todas as quatro séries analisadas se caracterizam pela alta dispersão dos dados, e não possuem tendências e sazonalidades.

Caracterização completa da madeira da espécie amazônica Paricá (Schizolobium amazonicum Herb) em peças de dimensões estruturais

A espécie amazônica Paricá (Schizolobium amazonicum Herb) apresenta rápidos incrementos em altura e diâmetro em poucos anos de cultivo e desenvolve uma madeira com pequena quantidade de nós e defeitos, característica fundamental na sua utilização para fins estruturais. O objetivo deste trabalho foi determinar as propriedades de resistência e rigidez de peças da madeira Paricá em dimensões estruturais, de acordo com a norma ABNT NBR 7190: 2011, bem como realizar a classificação visual das peças para determinação de defeitos como: nós, inclinação de fibras, empenamentos, rachas e fendas. Conclui-se que a madeira de Paricá é classificada como classe C 20 das dicotiledôneas e possui baixa densidade, boa resistência à compressão paralela, grande potencial de utilização na construção civil quando comparada com outras espécies e, em relação à classificação visual, poucos nós, grã direita e poucos empenamentos e distorções.

Revista Crás!: quadrinhos brasileiros e industria editorial

Este artigo tem como objetivo resgatar a trajetória das histórias em quadrinhos brasileiras na década de 1970, considerada de especial relevância para o avanço da arte gráfica sequencial no Brasil. Nesse período, observa-se, de um lado, iniciativas de pequenas editoras localizadas em vários estados brasileiros, e, de outro, empreendimentos feitos por editoras de grande porte na publicação de material nacional. Como estudo de caso, apresenta a revista Crás!, produzida pela Editora Abril, de São Paulo, que reuniu talentos veteranos e jovens da arte gráfica sequencial brasileira. A análise dessa publicação revela as dificuldades do quadrinho brasileiro frente às necessidades e limites das editoras comerciais e do mercado editorial no país.
