The objective of this paper is to relate the set of financial ratios that are directly related to the success of public traded companies using a methodological approach and the method of multivariate principal component analysis. This study consists in the use of profitability ratios, debt and liquidity, to define the relationship between financial ratios with the best public traded companies listed in the magazine Exame Melhores e Maiores of 2013. Multivariate analysis was used to reduce the dimensionality of multivariate data, making linear combinations of the original variables (financial ratios) and express the data in principal components that result in new variables that contains much of the original data. As a result, we got the optimal number of five principal components, and both represent 95.6% of the original data. Among of all financial ratios, we can highlight the direct relationship between profitability ratios for the first principal component, and the direct relationship between the liquidity ratios, both inversely related with non-capital participation rates and degree indebtedness to the second principal component

The information society is increasingly incorporating the immense volume of content available on the net. Access by electronic devices and the resulting ease of mobility and portability feed discussions on actual capacity of appropriation of this knowledge that circulates through cyberspace. Address and discuss the possibilities of educating across the network, therefore, gains more and more importance. On models of educational quality well developed – as is the case in Finland, for example-, Brazilian education is, year after year, failing in international marathons to achieve below average indexes required. Creates a field of analysis, in which this article arises, in the quest to understand more deeply the opportunity of use of Information and communication technologies (ICT) for a quality education, plunging by cultural issues that fall in the construction of objective conditions offered to students. This is an effort in understanding the historical factors that limit efforts to offering a quality education in Brazil.

With the advance of mathematical methods throughout the centuries, in particular with respect to the differential calculus, the notion of fractional derivative emerged with Leibniz and later developed by several well known scientists. Today that formalism is well used in the study of diffusion phenomena among other areas. We extend the fractional indices to matricial indices and develop a formalism to handle this generalized derivative, as well as other operators, functions and functionals in mathematical physics, originally defined for natural indices. Here we only consider 2x2 hermitian and anti-hermitian matrices. These matrices are associated to the well known Pauli matrices and Hamilton's quaternions. Applications with mathematical physics functions are presented

Aedes is synanthropic; associated with climatic conditions and urban environment. This study performed a retrospective evaluation of the climatic indices and the A. aeypti and A. albopictus infestation larvae rates (IP), registered from the month of October, 2005 to 2009, in the Araçatuba city, São Paulo State. There was no variation in the average temperature in the period (26.3°C). The rain falls were high in 2005 (133.5 mm3 ) fell in 2006, 2007 and 2008 (55.0 mm3 , 78.5 mm3 and 79.0 mm3 , respectively) and increased in 2009 (104.0 mm3 ). The infestation IP was 1.10, 1.39, 0.36, 0.28 and 3.30, respectively in 2005, 2006, 2007, 2008 and 2009, none of them were A. albopictus larvae. There was no association between IP and temperature, but there was significant difference (P <0.001) between the IP of 2009, with the IP of 2007 and 2008. This study it was concluded that among the environmental factors just rain influenced the rate of larvae, "infestation", committed only by A. aegypti.

Introduction: distance education is defined as a learning mode in which pedagogical and didactic mediation in teaching and learning processes is characterized by the use of information and communication means and technology by both teachers and students, and the development of educational activities at different settings and technologyand. Objective: evaluate the knowledge obtained by students from the last year of Odontology about distance education and their opinions about the subject. Methods: across-sectional descriptive exploratory study was conducted. Of the total 140 university students, 120 participated in the study. A self-applied questionnaire was developed with questions related to the student, the use of the Internet and distance education. The professional updating alternatives included were graduate courses and subscription to newspapers. Results: 29.2 % of the students use the Internet on a daily basis; only one student stated that he did not use the Internet. Of the students interviewed, 63.34 % did not know any form of distance education. As a consequence, 97.5 % had never taken part in a distance education course and 62.5 % stated that they did not know whether they would. Conclusions: results show that odontology students are prejudiced against nontraditional learning modes, though they use the Internet on a regular basis. Despite the existence of legislation regulating distance education, students are still concerned about its quality and legality.

The aim of this work was to examine both the influence of anatomical and technical aspects on fertility rate of sheep based on the performance of transcervical artificial insemination (TCAI). Transcervical artificial insemination was performed with traction of the cervix in 122 ewes using frozen semen from 11 rams, both Santa Ines breed. The data collected were: type of external cervical opening (CO) (P - papilla; FL - flap; DB - duckbill, S - spiral; RO - rosette), duration of cervical manipulation (2-3, 4-5 and 6-7 minutes), degree of difficulty in cervical transposition (low, moderate, high) and presumed semen deposition site (SC - superficial cervical; DC - deep cervical; IU - intrauterine). The influence of these variables on pregnancy rate was evaluated. Cervical opening type and duration of cervical manipulation had no influence (p>0.05) on fertility. The degree of difficulty in cervical manipulation influenced (p<0.05) pregnancy rate, since insemination classified as low grade had 52% of pregnancy, while those classified as high recorded only 20%. The presumed site of semen deposition influenced significantly (p<0.05) fertility. Pregnancy rates of deposition at each site were: UI – 45.8%, DC – 25.7%; SC – 15.4%. As expected, deeper depositions resulted in higher fertility. In conclusion, the performance of TCAI did not depend on the anatomical classification of external cervical opening of ewe and the duration of cervical manipulation within the range tested (2-7 minutes). The TCAI may have higher fertility rates if difficulties in the application were reduced and the semen deposition was deeper.
