La Formación Corumbataí y su importancia en la industria cerámica del estado de São Paulo - Brasil

El desarrollo acelerado del polo cerámico de Santa Gertrudes (provincia de São Paulo) en la década de 90, fue causado principalmente por la localización privilegiada de la materia prima asociada al desarrollo tecnológico, las grandes reservas, el acceso fácil por autopistas que facilitan la distribución de los productos y la proximidad de los grandes centros consumidores. Este desarrollo facilitó que este Polo tuviera un boom en el inicio de 2007 en la fase de madurez con una producción de 367 millones de metros cuadrados, transformándose así en el mayor polo cerámico de las Américas. de acuerdo con los estudios geológicos realizados en este trabajo, las rocas de la Formación Corumbataí, origen de la materia prima usada en el polo cerámico, fueron clasificadas en cinco litofacies: maciza, laminada, intercalada I, intercalada II y alterada. Estas litofacies, por sus características mineralógicas y químicas, fueron consideradas arcillas illíticas con porcentaje medio de fundentes. Tomando como referencia las Normas para baldosas cerámicas, las características cerámicas obtenidas en el laboratorio demostraron que la mayoría de la materia prima es compatible con el grupo BIIb (Absorción de agua entre 6 y 10%).

Mineralización de la paja de caña de azúcar en suelo adicionado con viñaza (suproducto de la industria del alcohol de caña de azúcar) y fertilizante nitrogenado

Cellulose is the most abundant vegetable organic compound, being derived mainly from plant residues. The decomposition of sugar-cane (Saccharum officinarum L.) straw was studied in a period up to 90 days, through variables related to the carbon cycle, such as respiratory activity and CM-cellulase (CM, cellulose microcrystalline) and CMC-cellulase (CMC, carboxymethylcellulose) activities. The treatments consisted of 0, 0.5 and 1.0% of straw, in the presence and absence of vinasse (a sugar-cane alcohol industry byproduct) and nitrogen fertilizer. The respiratory and cellulase activities increased up to the 14th day of incubation and later decreased. The respiratory activity was 1.9 and 2.3 fold larger (P < 0.05) in the soil with 0.5 and 1.0% of straw added, respectively, in relation to the control. CM- and CMC- cellulase activities also increased from 1.8 to 2.9 and from 2.3 to 2.7 fold, respectively. The vinasse addition enhanced CO 2 production and CM-cellulase activity, however, no significant effect was observed on CMC-cellulase activity. The addition of N reduced both respiratory and cellulase activities. The decomposition of the sugar-cane straw may enhance soil nutrient cycling increasing agricultural production. © 2006 Instituto de Investigaciones Agropecuarias, INIA.

Currently, the food market is a great competition. It is no longer unanimously in the CMC powder drinks, as in the past, xanthan gum, always seeking to develop more economic alternatives, such as guar gum. It is clear, therefore, it is of vital importance to understand thoroughly the operation of a particular product in different process conditions and with different materials so that we can develop and adapt both new processes and products to new market reality

A microbiota láctea: Importância na cadeia laticinista x deterioração

The work below boards critically the issues involved in the study of the microbiota of milk. It starts with a contextualization of the current dairy chain, in the presence of Normative Instruction - 51. Following are developed the most relevant concepts and definitions about the subject: the emergence of psychrotrophic, mesophilic acidifying metabolism, the injuries of marginal cooling. Next, the main genres that comprise the milky microbiota are described, in front of the following question: from what point the metabolism of these bacteria is no longer beneficial and becomes a deteriorating activity to the product? The paper does not end with classical conclusions or definite answers, but with questions, pointing out lines of research that can improve the quality of Brazilian milk, making it a differentiated and competitive product at the international market

Redução do tempo de setup de máquinas de usinagem em uma industria automobilística

Continuous improvement of industrial processes is one way to become companies more competitive in the market. For this, a fairly widespread use is the methodology of lean production systems, by eliminating waste. One of the tools of these systems is the method of rapid exchange of die or also called SMED, which will be applied in this study. The study aims to develop proposals for reducing the time of set up of two machines in two machining lines, watching also the ergonomics and safety conditions in this operations. The set up time reduction is justified among others, due to increase the machine productivity. In applying the connecting rod machining line, there were two types of exchange. Reductions in time to set up proposals reached values of 47% to one of them, and 55% to the other. It is important to underline that to reach this result, there was no need for large investments. In the application in block machining line, was developed an improvement in the ergonomic area. It was placed a pulley block that came to increase the time of tool change. Aiming to improve the security of the exchange, without productivity loss, the method was applied to reduce this time. It was developed two proposals.: the first would reduce that time by 19%, and does not require many resources of the company. The second involves the parallelization of the exchange, so that the reduction is 48%. However, this proposal requires one more manpower at the time of exchange and it is not always possible

Via Láctea: História (parnasiana) de uma paixão

Poesias (1888), Olavo Bilac’s first book, contains Via Láctea, a collection of sonnets of love that, in frank rupture with the romantic sentimentalism, is characterized by neoclassical moderation and contention. Universalizing treatment of the themes results in concealment of the particular circumstances in which the poems were composed. It is intended in these few pages to evidence the links between these texts and known episodes of the courtship of the poet and Amélia de Oliveira, the sister of Alberto de Oliveira, with the goal of providing an understanding of Via Láctea as a “love diary” in which the painful stations of a frustrated passion were registered.

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.

Desenvolvimento de bebida láctea potencialmente probiótica carbonatada: características físico-químicas, microbiológicas e sensoriais

The goal of this work was to develop a strawberry fl avored dairy beverages carbonated and fermented with potential probiotic bacteria. Four formulations of dairy beverages were elaborated: Control (BL); Fermented (BLF); Carbonated (BLC) and Carbonated Fermented (BLFC). In samples submitted for carbonation, a carbonator was used for the carbon dioxide (CO2 ) gas injection dissolved in drinking water and the cultivation consisting of lactic bacteria Lactobacillus acidophilusLA-5®, Bifi dobacterium BB-12® and Streptococcus thermophilus (Biorich, Chr. Hansen) was employed on the fermented samples. The samples were characterized by physical and chemical, microbiological and sensory parameters. The BLC sample showed the presence of yeasts and coliform counts, but the counts indicated that it was suitable for consumption in 28 days time. The BL presented average coliform counts above the limit established by the law after 21 days of refrigerated storage. The presence of lactic bacteria and CO2 and their effects on lower proteolysis indexes, lower pH values and higher acidity values were correlated with signifi cant inhibitory effect of contaminated microorganisms in the BLF and BLFC. The carbonation was not stimulatory for the growth of lactic crops, mainly in the genus Bifi dobacterium spp. and Streptococcus spp. The BLF drink presented greater sensory acceptance and purchase intention test results, however the carbonated beverage presented positive results, with mean values greater than 50% in the acceptance tests with potential inclusion as sensory differential in dairy beverages. Just BLFC drink was considered potentially probiotic, by presenting minimum counts of Lactobacillus spp. during storage. Further studies should be conducted with the technology of carbonation, since it has been proven the correlation of the presence of CO2 with inhibitory effect of contaminated microorganisms and lower physical and chemical changes of dairy beverages.
