Subsídios para implantação de trincheiras de infiltração na área urbana de Rio Claro/SP

The purpose of this work is to study the theme “infiltration trenches” in some of its main aspects, such as sizing methods and parameters related to this, in order to subsidize the installation of these structures in the urban area of Rio Claro/SP. For purposes of sizing, the “rain-envelope method” was used for its simplicity and direct application from the local characterization data and the IDF (intensity-duration-frequency) curve data. The method bases on the determination of the tributary volume of input and output device. The curve of values accumulated over time of the volumes tributaries to the device, which is built on the flow rates obtained from the local IDF curve, is compared with the value curve of his effluent volumes determined from the flow characteristics obtained from the infiltration soil. The maximum difference between the curves is the volume sizing. Five locations were chosen in the urban area of Rio Claro for implementation of these devices, considering the soil type, hydraulic conductivity of each area and lot size according to the Master Plan of Rio Claro. This work also presented an estimated reduction of the runoff in urban lots by using infiltration trenches.

Redução de tempo de setup de uma máquina de encartuchamento pela técnica SMED

Currently the market requires companies to adapt for they can have the lowest possible cost in their manufacturing, be it a good or service, thus obtaining a greater profit. For this profit the Toyota Production System applies lean manufacturing practices actions with reduced spending, smaller lots and stocks, generated by market demand. The technique allows SMED with few actions, changes and investments that time does not exceed one digit on your total time. This case study shows that only with standardization and use of inexpensive improvements, could reduce setup time on a machine for 70 minutes to time of approximately 48 minutes with little investment, demonstrating the viability of the tool presented

As festas no ambiente escolar e sua relação com as aulas de educação física

One of the interests of leisure is social and involves the festival. The holidays can be of different types and occur in different places, having lots of functions as the union of those involved, the development of creativity, fun and identification with the culture. The festivities are part of the play culture. The school, being an environment that deals directly and indirectly with the culture of organized behavior and appreciation of the discipline, often in second person through the formation of relationships, cultural transmission and access to the traditions of the groups around it. The entertainment component of culture in the school also finds himself sidelined in a society of work and a school that educates more to the labor market. The parties almost do not occur at school and when they happen, are given in order to make profits and sell consumer goods, apart from values that are intrinsic. In this study the objective was to deepen the study of parties, given that these are elements provides the establishment of the identity of a group of groups and of each individuals. When it comes to educating people, parties contributed to the emancipation of the human being which is cultural. Was developed a study in the field about the theme parties at the school, to understand whether and how it is being taught in schools, and what is its real importance for teachers and students, since we consider it fundamental to the development of culture and leisure culture of individuals. For this, we conducted a qualitative study based on a field research, using as a tool for collecting a semi-structured interviews with 52 students from 6th grade (7 years) from two schools at Ibitinga-SP, since one of them was a public school and the other a private school. Based on data collected from interviews and analysis, we found that the parties do not happen in schools, students do not learn what is leisure, and do not study or folklore festivals in physical...

Hormesis method for increasing oat straw with a view to viability of direct-seeding systems

In conservation agriculture, mainly under direct seeding, maintaining the vegetation ground cover is essential, since this serves as a reservoir of nutrients which are slowly released to plants by microorganisms. Some authors have sought to study increases in the amount of straw in the soil, in addition to slowing down the process of decomposition, with hormesis being one of the techniques used. This technique states that all chemical substances are both poisonous and nonpoisonous, with only the dosage determining whether they are lethal or not. This study aimed to evaluate the dry weight and agronomic characteristics of a crop of black oat subjected to hormesis. The experimental design was of randomised blocks, with 12 treatments and 4 replications, giving a total of 48 experimental lots. The treatments were: Haloxyfop-R Methyl Ester at dosages of 0.625, 1.25 and 2.50 g ha(-1); Glyphosate at dosages of 12.50, 25.00 and 50.00 g ha-1; 2,4-D dimethylamine salt at dosages of 100.00, 200.00 and 300.00 g ha(-1); Alterbane at a dosage of 500.00 g ha(-1); Salicylic acid at a dose of 100 g ha(-1); and a control. It was concluded that for the subdosages under test, the herbicides 2,4-D at medium dosage and Verdict at low dosage were shown to be the best treatments for conserving straw as ground cover under direct seeding.

Accelerated aging and electrical conductivity tests in crambe seeds

The aim of this study was to adapt the methodology of the accelerated aging and electrical conductivity tests for determination of physiological potential in crambe seeds. Six seed lots of crambe (cv. FMS Brilhante) were subjected to determination of moisture content, germination test, first count germination, emergence, and emergence speed index. For the accelerated aging test, the traditional methodology was used with water, and with a saturated potassium chloride and sodium chloride solution in three periods of exposure (24, 48, and 72 hours) at 41 degrees C; the electrical conductivity test was performed with four pre-soaking treatments (0, 2, 4, and 8 hours) and four soaking periods (4, 8, 16, and 24 hours) at 25 degrees C. The accelerated aging test with water for 72 hours and the electrical conductivity test with 2 hours of pre-soaking and assessment after 16 hours were effective for classification of the crambe seed lots in regard to physiological quality.
