Transformation of wealth produced into quality of life: analysis of the social efficiency of nation-states with the DEA's triple index approach

Although an essential condition for the occurrence of human development, economic growth is not always efficiently converted into quality of life by nation-states. Accordingly, the objective of this study is to measure the social efficiency-the ability of a nation-state to convert its produced wealth into quality of life-of a set of 101 countries. To achieve this goal, the Data Envelopment Analysis method was used in its standard, cross-multiplicative and inverted form, by means of a new approach called 'triple index'. The main results indicated that the former Soviet republics and Eastern European countries stood out in terms of social efficiency. The developed countries, notwithstanding their high social indicators, did not excel in efficiency; however, the countries of south of Africa, despite having the worst social conditions, were also the most inefficient.

MANAGEMENT OF A CARAPACE FRACTURE IN A SIX-BANDED ARMADILLO (EUPHRACTUS SEXCINCTUS)

An adult female free-ranging six-banded armadillo (Euphractus sexcinctus) was presented with an inverted L-shaped fracture of the left pectoral carapace. The fracture was stabilized with the use of three simple interrupted interfragmentary sutures of 2-0 nylon. After 7 days, wound dehiscence occurred, so sutures were replaced and the wound treated topically with castor bean oil cream. Healing of the fracture was observed after 14 days of this treatment.

Síntese e caracterização de ferritas de manganês e zinco visando aplicação como agente de contraste em diagnóstico médico

This work aims to synthesize the manganese and zinc ferrite, by the polymeric precursor method, in order to obtain materials with appropriate characteristics for the application in medical diagnosis techniques. The manganese and zinc ferrite powders with the composition of Mn(1-x)ZnxFe2O4, where x=0,23, were prepared and calcined in air at different times and temperatures. The X-ray diffraction (XRD) data show that the sample calcined at 400°C crystallize as ferrite (monophase), but in an inverted spinel structure (high content of iron occupying manganese tetrahedral site and manganese occupying the iron octahedral site). The samples calcined at temperatures between 600°C and 900°C shows the secondary phase of hematite and the sample calcined at 1100oC shows to be monophase in ferrite with normal spinel structure. The monophase powders of ferrite showed a reduction in the surface area and an increasing in the pore size for higher calcination temperatures. The magnetic analysis show that the sample calcined at 400°C presents satisfactory magnetization at room temperature, however, it behaves as diamagnetic material at low temperatures (10K). The powder containing hematite, without the partial substitution of iron ions by manganese, showed to have low transition temperature, and consequently low magnetization at room temperature. The hematite, when partially substituted, provides materials with irregular magnetization at the saturation region. The powder calcined at 1100°C shows high magnetization either at room temperature or low temperature (10K)

Estudo do metamorfismo de rochas de alto grau do grupo Araxá na região de São Sebastião do Paraíso - MG

This study focuses on metasedimentary rocks from the Passos Nappe in São Sebastião do Paraíso, southern Minas Gerais, Brazil. These rocks belong to the Internal Domain (Araxa Group) of the Southern Brasilia Belt, a Neproterozoic orogenic belt associated to the formation of the Gondwana Supercontinent. Rocks from the studied area are characterized by an inverted metamorphic gradient. Previously calculated metamorphic conditions show an increasing from geenschist facies at the base (450°C, 6 kbar), to upper amphibolite facies (750°C, 11 Kbar) at the top of the sequence. However, most of these estimates are based on Fe-Mg exchange thermometers and peak temperatures may be underestimated due to Fe-Mg exchange from cooling after peak metamorphism. In this study, we present new PT results for these rocks, based on metamorphic mineral assemblage LA-ICP-MS analyses. In the studied area, rocks from the top of the sequence have a typical granulite facies mineral assemblage: Grt+Ky+Kfs+/-Pl+liq. These rocks lack muscovite and have only minor amounts of Ti-rich, dark brown biotite. In a simplified NaKFMASH system the stability field for this mineral assemblage is bounded by the reactions Sil = Ky on the low pressure side, Ms+Ab = Ky+Kfs+liq on the low temperature side and for high-Mg bulk compositions Bt + Grt = Opx + Ky + liq on the high-temperature side. Minimum temperatures (considering post-peak reequilibration) of ca. 750°C are obtained by Fe/(Fe+Mg) values of 0.7 in garnets from a Grt+Ky+Kfs bearing sample. LA-ICP-MS results obtained for three samples show that rutiles included in garnets have up to 1847 ppm of Zr, which would translate into temperatures up to 830°C for a pressure between 12 to 15 kbar. Also for retroeclogite sample, the results indicate the contents of Zr in the garnet 537 ppm at a temperature of 708 ° C. It is noteworthy that several occurrences of retroeclogites occur in the upper part of the sequence and pressures...

Influência da luz LED em culturas de células-tronco mesenquimais in-vitro

Stem cells are defined as cells capable of self-renewal and differentiation into specialized cells when submited to external signalings in the enviroment. Among adult stem cells, mesenchymal cells occupy an important position because they can differentiate into mesodermal cells such as osteoblasts, adipocytes and chondrocytes. Cell therapy consists in the use of mesenchymal stem cells (MSC) in the treatment of degenerative diseases and harmed tissue reconstruction. Due to the longstanding and costly procedure for cultivation of MSC, it was proposed the use of low power light sources, such as light emitting diodes (LED), to optimize these factors. Recent works have shown a series of results from the influence of LED light on biological tissues such as increased rate of cell proliferation, increased RNA, DNA and ATP synthesis rate. The purpose of this study is to compare the biomodulator effect of LED light set at wavelengths 630nm ± 10nm and 805nm ± 10nm on the mesenchymal stem cells proliferation. For this, the mesenchymal stem cells culture adopted the procedure used in the Departament of Animal Reproduction and Veterinary Radiology of the Faculty of Veterinary Medicine and Animal Sciences of Botucatu. MSC were obtained from an adult horse bone marrow, and isolated by density gradient separation, with the FICOLL reagent and by centrifugation. The pellet containing the stem cells was removed and these were placed in low glucose DMEM culture medium, containing 10% fetal calf serum and antibiotics. The material was observed daily by inverted microscopy for monitoring the progression of the cells and subsequently the amount of cells were counted in a Neubauer counting chamber. The amount of MSC was obtained by cell culture seeded in 24 wells culture plate and segregated into three distinct groups: Group 1 was irradiated with wavelength set at 630nm ± 10 nm, Group...

Eficiência das companhias aéreas brasileiras: uma análise envoltória de dados

Studies about efficiency have gained dimension, in Brazil, since the early 90’s. Same decade that the Civil Aviation System suffers important changes in terms of regulations. Such transformations have echoed effects currently, with some significant trend for international standards. This paper focuses on one of the agents from the Brazilian Civil Aviation System, the airlines companies, which aimed on analyze and evaluate both passengers and cargo air transport, by using data envelopment analysis (DEA), during the period of 2005 to 2010. The yearbooks of ANAC, corresponding at the period from 2005 to 2010, were used as data base in this present study. The technique was applied to 14 companies, which through Stepwise process of variables validation was possible to compose a compact, but complete model, that could translate the reality of companies. This model was composed by one output, Total Income, and by four inputs, Total Costs, Total Domestic Passenger, Total Cargo and Total International Passengers. However, this approach has some flaws. Therefore in order to remedy it, it was required to apply the method Frontier Inverted, one of the alternatives proposed in the literature, which ensured an improvement in the context of efficiencies due to biggest discrimination of airlines. As a result of the DEA-BCC process, oriented by output, TAM 2005 was considered the most efficient company, however GOL and Webjet companies concentrated in 2007 their worst levels

Orientação espacial em pessoas com deficiência visual: um estudo de triangulação por meio de monitoramento remoto

This study was conducted to investigate how visually impaired people perform distance estimation tasks by movement and navigation during deprivation of effective perceptual and proprioceptive information. For that they performed the task of walking three distances, being the first and second of 100 meters and the third of 140 meters (triangulation) from a point of origin in open field on a inverted L shaped trajectory and then returning to the origin. The first and second tasks were driven by means of a guide with GPS adapted to the study coordinates, and the third one was freeform with three sessions, the first without perceptual and proprioceptive restrictions, the second without auditory perception, and the third in a wheelchair, without proprioception. The objective of this study was to indicate the differences in distance reproduction in relation to accuracy and investigate the spatial representation of participants in a navigation task, in which there is active movement, but no effective perceptual and proprioceptive information. Results showed that the average participants underestimated distances producing average angles close to the value of 45°. And by means of the "t" students test no significant differences between subjects can be pointed out. To achieve these results we used remote monitoring by GPS and software TrackMaker.

Tarefas de triangulação com restrições perceptuais em pessoas com deficiência auditiva: um estudo por meio de gps

This study aimed to investigate how people with hearing disability perform tasks of distances estimation for locomotion and navigation when deprived of effective perceptual and proprioceptive information. For this, participants with hearing disability went three distances being the first and second 100 meters and the third 140 meters (triangulation) from a source point in an inverted L open field trajectory and then returned to the origin, and the first two were driven by a researcher guide with adapted GPS coordinates of the study, and the third being three free-form sessions, the first one without any perceptual and proprioceptive restriction, the second without visual perception, and the third on the wheel-chair, that is, without proprioception. The results showed that people with hearing disability without the knowledge of the path do not possess satisfactory accuracy but when they learn the way even with the restriction of visual perception and proprioception they can return to the starting point in a task of triangulation. The "t" students test with a significance level of 5% (2.131) indicates significant differences between the first task without any perceptual restriction and the third where they performed in the wheelchair. To achieve these results we used remote monitoring via GPS and the TrackMaker software.
