Integrando técnicas e procedimentos de gestão de operações: uma aplicação em um banco comercial Brasileiro de grande porte

Na conjuntura atual, eliminação de custos, satisfação dos clientes e aumento da produtividade é algo, no mínimo, desejável para as organizações. Exatamente neste viés, a presente pesquisa aborda a utilização de técnicas e filosofias amplamente abordadas e difundidas em gestão de operações; porém, em vez de usá-las isoladamente, propõe-se sua utilização conjunta. Neste contexto, integram-se o Mapeamento de Processos, a Gestão da Capacidade, a Teoria das Restrições (TOC) e o Empowerment. Por meio de entrevistas junto aos funcionários, da coleta de dados e da observação direta do processo produtivo, foi possível mapear os processos, definir as capacidades, identificar os gargalos, levantar o nível de maturidade dos funcionários e propor soluções por meio da aplicação do Empowerment. Como resultado, contatou-se a possibilidade de melhoria no sistema de concessão de créditos da empresa pesquisada (Banco), possibilitando um aumento da produtividade em 27,78% e uma redução de custos da ordem de 4,5 milhões de reais.

Metodologia experimental para avaliação de custos de produção e utilização de biodiesel: estudo de caso de quatro ésteres metílicos e óleo diesel comercial

Considerando que o Brasil detém uma vasta gama de matérias-primas para produção de biodiesel, e também que há a possibilidade de produção em pequena escala, prima-se por estudos de cunho econômico a partir de metodologias de fácil execução. O objetivo do trabalho foi demonstrar uma metodologia e sua aplicação para avaliação dos custos inseridos dentro do processo produtivo e de utilização do biodiesel. A metodologia foi aplicada a biodieseis originários de óleo de soja, girassol, frango e sebo bovino, dos quais se avaliaram economicamente os custos fixos e variáveis para conversão química dos óleos e gorduras em ésteres metílicos, em uma planta de produção experimental. Os custos de produção para cada uma das quatro citadas são distintos em função do valor inicial por litro de cada uma. Também fora avaliado o custo específico e o consumo específico de cada um dos biodieseis, a fim de determinar a diferença em relação ao óleo diesel comercial. No estudo de caso, os resultados mostraram vantagens para o óleo diesel, tanto no custo quanto no consumo. Comparando-se os biodieseis, o de sebo bovino apresentou-se com o menor custo de produção e o menor consumo.

Empresas multinacionais e desempenho comercial do Brasil: uma revisão da literatura

Fazemos uma releitura dos estudos empíricos sobre empresas multinacionais (EMNs) e comércio exterior no Brasil a partir dos modelos teóricos e empíricos de comércio internacional com firmas multinacionais. Percebe-se que aqueles estudos não examinam como características econômicas do país (Brasil) condicionaram a emergência e tipo das EMNs e, assim, seus respectivos impactos sobre comércio exterior. Conseguem isolar, nas análises de impacto comercial, evidências dos serviços tecnológicos das estrangeiras, relativamente às domésticas do mesmo setor, mas não examinam se essas firmas se concentraram ou não em atividades com vantagens comparativas no país, o que seria crucial para determinar seu impacto comercial comparativo.

Estudo Comparativo de Juntas Soldadas a TIG e Laser Empregando-se Ti com Pureza Comercial Utilizado em Prótese sobre Implantes

Welding in the dentistry has been used for great part of the specialized dentist-surgeons in the implants area to solve prosthesis supported by implant adaptation problems. The development of new equipments Laser and TIG allowed a larger use of these processes in the prosthesis production. In this work, it was studied welded joints made by Laser and TIG, using commercial purity titanium, cpTi, applied in prosthesis supported by implants. The weld characterizations were carried out by light microscopy, EDS_elementary mapping, microhardness and tensile test. Through metallographic characterization, the weld bead presented a martensitic microstructure in the Laser welding process, originated from shear provoked by deformations in the lattice. This caused structural changes of the transformed area, which determines a fine plate-like morphology. In the weld bead from TIG, besides presenting higher hardness, was observed formation of Widmansttaten structure, which is characteristic of a geometric model, resulted of new phase formation along of the crystallographic plans. The martensitic structure is more refined than Widmansttaten structure, due to the high-speed cooling (10(3)degrees C/s) imposed by the Laser process.

Avaliação Comparativa da Agressividade de Meloidogyne javanica e M. incognita à Variedade SP 911049 de Cana-de-açúcar

Nematodes cause extensive losses to sugarcane in Brazil and also in other producing regions. Meloidogyne incognita, M. javanica and Pratylenchus zeae are the key species for this culture worldwide. In the present study, the aggressiveness of M. javanica and M. incognita to sugarcane variety SP 911049 was evaluated comparatively,. The following parameters were compared: reproduction factor (RF) of these nematodes, effect of nematodes in the natural incidence of pests, and the influence on the development and technological characteristics of sugarcane. Considering the data of RF, biometrics, natural infestation of pests, mortality of plants, and technological variables, it was concluded that M. javanica was more aggressive to sugarcane, although its rate of multiplication was much smaller than the one of M. incognita.

Estudo morfológico e histomorfométrico sobre variações sazonais do ducto deferente de codorna da variedade italiana

In the autumn the vas deferens of the Italian variety of domestic quail appeared as a single, thin, and straight duct along its total extension. Thus, transversal histologic sections of this duct showed a circular tubular shape. The pseudoestratified columnar epithelium that lined the vas deferens presented longitudinal folds which invaded the lumen frequently empty of spermatozoa. Although in the winter, spring and summer the usual morphological appearance of the quail's vas deferens was seen as a highly coiling duct. So, each transversal histologic section of the vas deferens, in all the segments, showed parallel cut sections of the duct being irregular in shape and variable in number and interconnected by the adventitial loose connective tissue. In these observations, the tubular lumen was totally performed by spermatozoa and seminal fluid. Consequently, with previous base on the testis kinetics of the Italian quail variety, it was concluded that the spermatozoa production, followed by emission, storage and ejaculation of spermatozoa through the vas deferens did not stop during the winter, spring and summer, but ceased in the autumn the quiescent phase of the circannual reproductive cycle in this bird.

Controle da artrite-encefalite caprina, em um capril comercial endemicamente contaminado

CAE is caused by a lentivirus. The animals are mainly infected when taking contaminated colostrums and/or milk. This study proposed a CAE control strategy without sacrificing contaminated mothers. Thirty-nine female kids, born to CAE seropositive mothers were isolated from their mothers at birth and fed heat-treated colostrums and pasteurized milk from seronegative goats up to two months of age. All kids were submitted to three-monthly serological tests from birth to 12 months; seropositives were segregated from the herd. The control group consisted of 12 kids born to seropositive mothers that remained with their mothers. Diagnosis was the same, but seropositve animals were not segregated. At the end of 12 months, 34 (87%) animals from the experimental group remained seronegative with 76% to 98% confidence limits; in control group animals, the accumulated negativity rate was 17%, with 0% and 38% confidence limits. These results show that the proposed plan is viable to assure disease control in contaminated herds and that without it contamination can pass to animals born to infected goats.

The aim of this research was to identify the insects visiting flowers of sweet pepper and evaluate the effects of entomophilous pollination as a whole and, more especifically, of honeybees as pollinators of this crop. This study was carried out in the municipality of Taubaté, State of São Paulo, Brazil (21°01'S; 45°29'W; altitude: 570 m) from April to September, 2002. Insects were collected in thirty-six plants during 10 minutes/hour between 6:00 and 17:00h during days of maximum blooming. Twelve plots were subjected to the following treatments: (1) open-pollinated plots, freely visited by insects; (2) caged plots; (3) caged plots containing a hive of honeybees. Twelve species of insects visited the flowers. Exomalopsis spp. (Hymenoptera, Apidae) were the commonest ones (53,9% of visits). Fruits yielded in treatments (1) and (3) were heavier, presented higher diameter, thicker pericarp and more seeds per fruit than fruits in treatment (2). Results showed that fruits from insect pollinated plots presented better quality. Honeybeesas as pollinators were efficient as the other insects. sweet pepper, Capsicum annuum L., Solanaceae, pollination, Apis mellifera, honeybee.
