Sistema de Gestão Integrado: a implantação de uma parceria no município de São José dos Campos

O artigo pretende descrever e analisar a implantação da parceria que se firmou entre a Secretaria Municipal de Educação de São Jose dos Campos e o Instituto Embraer de Educação e Pesquisa, sob a consultoria da Fundação Pitágoras com o objetivo de instalar um modelo de gestão empresarial na rede de ensino municipal. Para tanto, utilizou-se, dados de matrículas, documentos oficiais e entrevistas realizadas em 2008, com representantes do Instituto Embraer, Fundação Pitágoras e Secretaria Municipal de Educação. O artigo evidencia que a adesão ao modelo de gestão empresarial nomeado Sistema de Gestão Integrado (SGI) não se deu pela necessidade, mas pela oferta do Instituto Embraer. Além disso, constatamos que a parceria não pode garantir a prometida educação pública de “qualidade” na perspectiva já que organiza o sistema educacional em moldes empresariais visto que o SGI pode influenciar na responsabilidade dos estabelecimentos de ensino ao elaborar e executar a sua proposta pedagógica, prejudicando a autonomia pedagógica das escolas.

Avaliação comparativa das perdas de água por evapotranspiração em mesocosmos colonizados por diferentes macrófitas aquáticas

Water loss increase through evapotranspiration is one the most important modes of interference of weeds in water bodies, especially in water storage reservoirs. Thus, this research was conducted to compare the water losses in mesocosms colonized with the aquatic weeds Myriophyllum aquaticum,Brachiaria subquadripara,Echinochloa polystachya,Typha latifolia and Pontederia lanceolata. The evaluations were carried out in July 2004, in three 4-day periods. The water losses were evaluated based on the amounts of water necessary to restore the existing water level before each evaluation period. The colonization of the aquatic weeds increased the water losses in the mesocosms, with the highest losses being observed in those colonized by T. latifolia, between 3.54 to 4.71 times the water surface without aquatic weeds. The losses in the mesocosms colonized by M. aquaticum,B. subquadripara, E. polystachya, and P. lanceolata were statistically similar and promoted increases between 1.54 to 2.21 times the free surface. The results showed that aquatic weed control is important to prevent water losses in reservoirs used for water storage.

Aging of plasma-activated copper and gold surfaces and its hydrophilic recovery after water immersion

A significant increase of surface hydrophilicity of copper and gold surfaces was obtained after atmospheric pressure plasma treatment using the surface dielectric barrier discharge with specific electrode geometry, the so-called diffuse coplanar surface barrier discharge. Surface wettability was estimated using the sessile drop method with further calculation of the surface free energy. After the plasma treatments, it was observed that the treated surfaces exhibited hydrophobic recovery (or aging effect). The aging effect was studied in different storage environments, such as air, low and high vacuum. The role of plasma and the reasons of the following aging effect are discussed with respect to the observed hydrophilic recovery after immersing the aged surfaces into deionized water. The changes in the surface morphology, composition and bond structure are presented and discussed as well. (C) 2013 Elsevier B. V. All rights reserved.

Propriedades tensiométricas do peritônio da paca (Cuniculus paca) a fresco e conservado em glicerina 98%

In constant searching for alternative biological material to perform implants and new options of experimental animal models, the objective of this investigation was to describe the mechanical properties of the peritoneum paca (Cuniculus paca Linnaeus, 1766) fresh and preserved in 98% glycerin. Samples of fresh and preserved in glycerin for periods of 30, 60 and 90 days were subjected to mechanical tests. Four adult animals, male or female, with mean body weight of eight kilograms, were used for collecting samples of the peritoneum. All tissues preserved in glycerin 98% showed a decrease in stiffness and increase in ductility and toughness. Considering the maximum force applied to the peritoneum, significant increase was observed in values (p<0.01) of samples stored for 60 and 90 days when compared to fresh material. In relation to the stretch variable, an increase was observed in all storage time of glycerin samples, verifying significant difference (p<0.01) when compared with the fresh samples. The variable area also showed significance (p <0.01) between the values of the fresh samples (5.40 mm(2)) and preserved in the glycerin by periods of 30 days (4.50 mm(2)), 60 days (9.00 mm(2)) and 90 days (7.20 mm(2)), thus indicating that the area of this membrane increased by 0.033 mm(2) per day. Generally, it was concluded that the 98% glycerin is a substance effective for the preservation of the peritoneum of the agouti paca, therefore improves its mechanical properties allowing the support membranes greater deformation forces. Thus, the results obtained in mechanical tests of the peritoneum of paca suggest its use as an alternative biological material.

Classificação de workflows baseados em web services

Over the last decades changes have occurred in communication within and between enterprises, made easier by technologies suchas E-commerce, Internet, ERP systems and remote meetings and there was a rapid progress in network technology, which has changed the way business is done. A standardized way to offer services over the internet is using web services. Web services are a kind of remote procedure call and are generally used to integrate systems, independent of language, both client and server. It is common to use several web services run in sequence to perform a business process. To this type of process, gives the name of workflow. Thus, Web services are the primary components of workflows. A tool that provides a way of visualizing the behavior of a workflow can assist the administrator and is required. The present work presents the development of a tool that allows the administrator to classify visually services components and evaluate their importance in the final performance of a workflow. As proof of concept we used several virtual servers and computers where each computer has received a set of web services. A proxy was added between each call of workflows collecting relevant information and storing them in a database for later analysis. The analysis was based on Quality of Service parameters

Determinação por meio de planejamento de experimentos da influência do lixamento nas medidas de dureza com durômetro portátil de método UCI

The hardness has an important role in quality control, in research studies and metallurgical and mechanical specification, selection and comparison of various materials. This property is of extreme importance in the oil industry because it is a determining factor to ascertain the safety of the material used in pressure vessels and pipelines. Due to the inability to stop the equipment while checking the hardness, the hardness testers are widely used portable method UCI, its great advantage is the fact that an essay fast, simple realization and not be considered a non-destructive testing with a good relationship money. The objective is to determine if there is significant difference in hardness measurements between 80 and 1200 sandpaper using a portable hardness tester UCI method, the material applied in gas storage spheres composition ASTM 516 Gr 70. After determining the number of homogeneity, we performed the hardness profile to isolate the major factors influencing the hardness part: cold rolling and segregation of impurities. Factors Cooling and sanding were analyzed using the method of design of experiments (DOE), in which it was demonstrated that neither variables nor their interactions, has significant influence on the hardness measurements by portable MIC 10. This fact will lead to reduction in time and cost for surface preparation

Lisianthus vase life after 1-methylcyclopropene and salicylic acid postharvest treatment

This study evaluated the effects of application of 0.5 µl L-1 1-methyl-cyclopropene (1-MCP), 1000 mg L-1 salicylic acid (SA) and the interaction between the two products at room temperature and pre-exposure at 9±2°C for 24 h in maintaining postharvest quality of lisianthus flowers. After applying the treatment, the flowers were kept in jars with water, stored at 24±2°C. The SA treatments proved ineffective, presenting symptoms of phytotoxicity, with high rate of bent neck and yellowing of petals, both at room temperature and in cold storage, and propitiate the emergence of pathogens. The association between 1-MCP in pre-exposure to 9±2°C for 24 h increased the durability of the stems in six days compared to the control treatment, with less symptoms of bent neck and swelling of stems.

Irradiação e atmosfera modificada passiva na qualidade pós-colheita de goiabas 'Pedro Sato'

The aim of this study was to evaluate the effect of gamma radiation associated with modified atmosphere on postharvest quality of guavas ‘Pedro Sato’. It was used guavas from the region of Vista Alegre do Alto/São Paulo/Brazil. After harvest, the fruits were immediately transported to the Fruit and Vegetables Laboratory from the Agroindustrial Management and Technology Department, Agronomic Sciences College - UNESP - Botucatu / SP, where they were kept at 10 ° C and 90-95% RH in cold storage, for 28 days. It was used the randomized design, with factorial scheme 5 x 5, three repetitions. The first factor consisted of the following effects: control 1 (without package or irradiation), control 2 (polystyrene package/PS + package low density polyethylene/LDPE and without irradiation), treatment 1 (PS + LDPE and 0.2 kGy ), treatment 2 (PS + LDPE and 0.6 kGy) and treatment 3 (PS + LDPE and 1.0 kGy). The second factor consisted of the evaluation periods: 0, 7, 14, 21 and 28 days. The analyses were: firmness, soluble solids (SS), titratable acidity (TA), maturity index, pH, respiration rate. Concluded that high doses of irradiation promoted a negative effect on physical-chemical characteristics of guava ‘Pedro Sato’, verifying that only the lowest dose associated with modified atmosphere provided fruits with higher quality and acceptability, due to higher maturation rate and soluble solids obtained. Regarding the days of analysis, there were no positive effect of the treatments during storage, where only the early days promoted better values for the variables studied.
