Implicações federativas da emenda Ibsen Pinheiro

Since it was proposed, the Ibsen Pinheiro amendment has given rise to a huge debate in Brazilian society. This amendment proposes to share the revenue generated by royalties and special participations from offshore oil drilling between all municipalities and states, using for this the states and municipalities participation funds. This new distribution is a great rupture with the current model, which mandates that these resources should only be distributed to producing municipalities and states. Since the new proposal affects all offshore operations, and not only those in the new pre-salt areas, the producing municipalities and states would face an immediate loss of revenue in the scale of billions of reais. This study's objective is to analyze the validity of the criteria of redistribution of the government participations proposed by the Ibsen amendment. In this sense, we present the current Brazilian government participation model, focusing on the overfinancing of subnational spheres generated by this model, and compare it to a distribution simulation using the Ibsen amendment criteria. This comparison shows that the current beneficiaries would face a significant loss of revenue, and a distribution that favors the poorest regions of the country, consequence of the states and municipalities participation funds use. The study's last part discusses the various arguments in favor and against the amendment, especially those of constitutional character, most of which are contrary to the Ibsen amendment

Análise morfológica de brânquias de peixes Oreochromis niloticus (tilápia) expostos ao níquel

Water is an essential factor in maintaining the vital functions of living beings. We have observed a growing commitment of quality, are due to pollution from many sources and even entire watersheds, whether for industrial waste, sewage, or for substances used in farming such as pesticides, herbicides and fertilizers. Nickel is the 24th most abundant element on earth, is a heavy metal that, in the form of chloride, is a proven genotoxic and mutagenic. Due to its industrial use, there was considerable increase of its concentration in surface sediments. Fish combine characteristics that make them excellent experimental models for aquatic toxicology studies, which are particularly usable as warn about the potential danger of chemicals or the possibility of environmental pollution. Due to impaired water quality and the few published studies relating the nickel with the tissue change, this study aimed at assessing the consequences of the presence of nickel in the aquatic environment. For this analysis, we used individuals of Oreochromis niloticus, exposed for 96 hours at three different concentrations of nickel dissolved in water compared to a control group. After exposure, the gills were removed and these were analyzed by ultramorphological, histological and histochemical analysis. The results indicate that all concentrations used in the experiment altered the histophysiology of exposed individuals. We observed the following changes: rupture of paviment cells, thus resulting in bleeding, loss of microridges surface of these cells and epithelial loss in the gills of all animals in all treatments with nickel chloride, the histochemical analysis showed non-proliferation of chloride cells. However, there was a dose-dependent increase of mucus cells in all animals. Therefore, nickel has toxic potential to fish, from the smallest concentration used up to twice as permitted by law, indicating... (Complete abstract click electronic access below)

Laserterapia em lesões de coluna na Medicina Veterinária

Lasertherapy is a method of non-pharmacological treatment and surgery that can be used in several injuries and in various tissues, from bone fractures to tendonitis, skin wounds and damaged nerves, permitting the recovery of these structures and their functions without causing any side effects. Laser therapy aims to restore patients that suffered various injuries, such as bone fracture, inflammation, edema, tendon rupture, spinal cord injury, among others, without invasive intervention, and the results obtained in several studies and case reports have proven the high potential of this therapy to become an official treatment of various pathological changes

Polimorfismo do gene IL6 candidato à predisposição à rotura prematura de membranas pré-termo e ao trabalho de parto pré-termo

Introduction: Preterm Labor (PTL) and Preterm Premature Rupture of Membranes (PPROM) cause severe complications for both mother and fetus. Among the risk factors associated with preterm labor and PPROM, genetic predisposition has been gaining importance. However, the association between polymorphic genes and the pathogenesis of PTL and PPROM remains elusive. A better understanding of the genetic mechanisms underlying these adverse pregnancy outcomes may enable the identification of high risk patients and allow new approaches to minimize the deleterious effects of prematurity. Aim: To determine the association between maternal IL-6 polymorphism gene and the occurrence of PTL and PPROM. Patients and Methods: The study included 109 patients with prior history of PL and/or PPROM that delivered prematurely at the Obstetrical Unit Care of Botucatu Medical School, UNESP between 2003 and 2012. The control group consisted of 68 patients that delivered at term, matched to the case group by age, ethnicity, and sex of the newborn. Oral swabs (Cath-AllTM – Epicentre Biotechnologies) were collected for analysis of genetic polymorphisms by PCR. Statistical tests were performed to compare genotype, clinical and socio-demographic data from the groups. A p-value of <0.05 was considered significant. Results: The sociodemographic characteristics in both groups were homogeneously distributed. The frequency of the polymorphic allele C, associated with less production of IL-6, and therefore thought to be protective against PTL and PPROM, was 32,5% in the study group and 30,9% in the control group, without statistically significant differences. Conclusion: Considering the sample size included in this study, the frequency of the mutated allele is similar in pregnant women who delivered at term and gestational complications as PTL and PPROM

Among the main results we can highlight: 1) There is a rupture between kindergarten and primary teaching, the kids have noticed and reported the structural and environment differences, they feel lack of proper spaces for play and of resources like: playground, sandbox and toys in general. 2) The childhood of researched kids appears as a life period different from the adult life, playing appears as a characteristic of that moment. 3) The importance of ponder the pedagogical practices aimed at this ages, so that we can consider the play as an ally in this process, allowing that the kids have more possibilities in the learning process

Caracterização físico-mecânica de elementos estruturais roliços perfilados de Amaru

The study of physical and mechanical properties of wood is essential for its structural use and it is of great importance to the construction industry. Thus, this study aimed to determine the physical and mechanical properties of the wood Amaru - a hybrid of Eucalyptus, developed by Plantar Projects and Forest Products Ltda. In order to determine the properties of Amaru, round samples were used, which were provided to the Laboratory of Wood and Wooden Structures of the School of Engineering of São Carlos, University of São Paulo - LaMEM / EESC / USP. For the characterization of the physical properties, the apparent specific gravity and moisture content of the samples were determined. To the mechanical characterization, the following properties were evaluated: strength and stiffness in compression, strength and stiffness in bending, shear and tension. The procedures of the tests performed in this study were done according to the recommendations of the Brazilian Wood Standard ABNT NBR 7190:1997. The specimen used were confectioned in actual dimensions, according to as those used in the construction system proposed by Plantar. The results obtained from the tests performed showed that the mechanical properties approached the values proposed by the Wood Standard NBR 7190. The visual grading was important to provide a primary idea about the failure modes to be obtained from the tests performed. The bending test showed the modulus of elasticity (MOE) and Modulus of Rupture (MOR), which resulted in 15822 MPa and 101,7 MPa, respectively. The compression test resulted in values Ec0,m and fc0, 15698 MPa and 50,7 MPa. The tensile strength (ft0) of this hybrid was calculated and its value obtained was 60,8 MPa. The shear strength (fv0) was 8,2 MPa. The results obtained from the tests are the basis for engineers and architects to design structures using wood species Amaru

Quimioestratigrafia do vulcanismo ácido mesozóico da província magmática do Paraná: porção SE do estado de Santa Catarina

The Mesozoic acid volcanism of the Paraná-Etendeka Province can be considered as one of the biggest events of its kind in the Earth's surface, and its study have attracted special interest in characterizing the end of magmatism that preceded the rupture process and the formation of continental Africa and South America Although significant, the acid volcanism featuring Members Chapecó Palmas and Serra Geral Formation represents only 2.5% of the total generated by the magmatic rocks and perhaps therefore the existing literature on these rocks is well less significant than that on the basalts. However, there are still aspects still unclear about the origin and evolution of these rocks in relation to the associated basalts. Thus, two profiles were selected, called RA and TA, which be a systematic collection of samples from the base where the Botucatu Formation sandstones occur at the top, where they observe Palmas acid rock type. These samples should be analyzed for major, minor and trace elements and treated in specific diagrams to define the vertical variation lithochemistry and their possible relationships with the associated basalts

Análise do desempenho físico-mecânico de painéis compensados de Pinus sp. produzidos com adesivos aquosos a base de poliacetato de vinila e de homopolímero vinílico

This study aimed to evaluate the physico-mechanical performance of three PVA adhesive formulations according to the Brazilian standards for plywood testing and to evaluate the results with those presented in the technical literature and specified in normative documents. The study presents the production process of the panels, the obtaining of samples and, finally, the implementation of physico-mechanical characterization tests based on plywood Brazilian standards. For the panels production it was used a gramature of 120 g / m² and applied a pressure of 15 bars and two temperature combinations and pressing time for each adhesive. The commercial adhesives used were PVA 1810, PVA 1060 and Vinyltec 239. The physical tests conducted were thickness swelling, density, moisture content and water absorption. The mechanical tests were static flexion, for the determination of elasticity modulus (MOE) and rupture modulus (MOR), and shear in the glue line. Among the three formulations studied none showed good performance in the presence of water. However, other trials in the adhesive showed better results and closer to the commercially equivalent used, in the case the urea-formaldehyde, was the PVA 1810, that can be applied in non-structural uses and in environments without the presence of moisture

Usinagem da liga de níquel inconel 718 com pastilhas de cerâmica

The machining of super alloys resistant to high temperatures such as nickel alloys, inconel 718 specifically, is a very difficult job to obtain improvements in the process, due to the difficulty of machining at high cutting speeds, the use of these alloys in industries showed great developments in recent years, its application in aeronautical industry spread being used in vane turbo, compressor parts, props and set elements. The automotive, chemical, medical and others also took advantage of the great features of inconel 718 and has used the material. The high temperature resistant alloys have high machining difficulty, a fact that is associated with high cutting forces generated during machining which result in high temperatures. High levels of temperatures can cause deterioration of the cutting edge, with subsequent deformation or breakage, wear most common obtained in machining such materials are flank wear the formation of built-up edge for cutting and notch wear. The experimental part of the work consists in machining of nickel-based alloy Inconel 718 heat treated for hardness, using a tool based ceramic silicon nitride Sandvik (Si3N4) in order to compare the best results obtained in the master's thesis of SANTOS (2010) who used a tool ceramics also the basis of silicon nitride which was developed in the doctoral thesis of SOUZA (2005). Assays were performed on a CNC lathe and was noted for each cutting edge results obtained. Tests were made starting from an initial condition of the tool with cutting speed of 200 m/min, feed 0.5 mm and 0.5 mm depth of cut was reduced cutting speed for the subsequent tests with the same conditions of feed and depth of cut. The tool presented wear instant under two 200 m/min and 100 m/min, premature rupture of 50 m/min and finally cut provided with difficulty... (Complete abstract click electronic access below)
