Equilíbrio de cavalos da raça Quarto de Milha participantes da modalidade de três tambores por meio de proporções corporais

Based on the concept that horses have balanced symmetry between its anatomical regions, the aim of this study was to introduce a method of assessing the balance of equines through body proportions. Altogether twelve linear measurements, using metric tape, were measured in 234 horses Quarter Horses for evidence of barrel racing. From these measurements were built nine body proportions, each one given by the ratio of two specific measures, and the effects of sex, weight, age and degree of blood on the balance were evaluated. To check the significance tests we used the F statistic, considering P<0.05. It was found that the linear measurements ML2, ML3 and ML5 were mainly responsible for the disproportionality of the horses evaluated. The effect of sex was significant (P<0.05) for four proportions (R1, R3, R4 and R9) and females were more distant from the concept of balance than males.

Análise de investimento em confinamento bovino no centro-oeste brasileiro: um estudo de caso.

This study analyzed the economic viability of an investment in feedlot cattle on a farm in the midsize state of Goias. The research identified that different thematic studies whose interests have focused mainly on cost analysis and profitability punctual. Differently, this study used the approaches of the Discounted Cash Flow (DCF) and the Real Options Theory (ROT). The first used the projected cash flow for 10 years and a discount rate determined by CAPM at 8% p.a. for containment of heads 400. The second was modeled by the binomial model of Cox, Ross and Rubinstein (1979) incorporating the option of waiting. This methodology has not been employed in Brazilian cattle industry. The search results pointed to the economic viability of the project when considered possible scenarios for the different price ranges of the ox that state bushel. In addition, the TOR proved to be a more robust tool for investment analysis, by incorporating the flexibility of farmers to wait for the right time to make the confinement.

Innovation efforts and performances of Brazilian firms

We analyze the relationship between innovation and firms' performance in Brazil using a comprehensive database that cross-references innovation information by PINTEC (Technological Innovation Research) of the IBGE (Brazilian Institute of Geography and Statistics) and financial information from Serasa and Gazeta Mercantil. Results from the structural equation modeling suggest that variables associating with investments in innovation, which are connected to the innovative effort of a company, do not explain financial performance significantly.

Histórico e aspectos tecnológicos do processamento da linguiça cuiabana

This paper reports the data on the cuiabana sausage historical aspect, and from the study performed on its technical/sensory characteristics. Four formulations of cuiabana-type sausage were prepared, varying the basic raw material (bovine, chicken and swine meats). For processing these sausages, the raw meats (beef, chicken and pork) were cut into cubes and together with the other ingredients (garlic, cheese, pepper and chives) they were weighed and homogenized. The resulting mixture was refrigerated for 24 hours for intensifying the flavor. Thereafter, it was stuffed into natural casings. These prepared samples were characterized on the physical-chemical profile and on the shelf life under refrigeration for over a seven day-storage in order to assess the microbiological contamination (total coliforms and fecal thermotolerant bacteria), sulphite-reducing clostridium, Salmonella spp., coagulase-positive Staphylococcus), and pH. The sensory evaluation and statistics analysis were carried out on the different types of laboratory- processed cuiabana sausage. Introducing over time changes in the cuiabana sausages formulation are positive factors; therefore, variations in the formulations it is feasible to get a better final product than that original one, and it might be resulted from the market demand.

Cardiomyopathy and cell therapy: ejection fraction improvement and cardiac muscle mass increasing, after a year of bone marrow stem cells transplantation, by magnetic resonance image

The idiopathic dilated cardiomyopathy (IDC) is one of the major public health problems in the western world. Patients with IDC in functional class IV (New York Health Association - NYHA), even after therapeutic optimization, have high mortality. Stem cell therapy has emerged as a potential therapeutic option for cell death-related heart diseases and several positive effects were assigned to cell therapy in cardiomyopathy. The aim of this study was identify short-term result of cell transplantation in idiopathic dilated cardiomyopathy patients (IDC) who were treated by transplantation of autologous bone marrow mononuclear cells (BMMC). Intracoronary injections of autologous BMMC were performed in eight patients with severe ventricle dysfunction (mean of left ventricle ejection fraction – LEVF=20.03%), cardiac mass muscle around 156.2 g and NYHA between III and IV grades, other 8 IDC patients received placebo. The IDCs were followed - up for one and two years, by magnetic resonance imaging (MRI). The results after one year showed significant improvement in LVEF (mean=181.4) and muscle mass increasing (mean=181.4 g), after two years the LVEF continued improving, reaching a mean of 32.69% and the cardiac muscle mass kept stable (mean=179.4 g). Excepted for one patient, all the other had improvement in the NYHA functional class. The placebo group did not show any improvement. We believe that BMMC implant may be a beneficial therapeutic option for IDC patients.

Lê Cycles and Milnor Classes of Compact Hypersurfaces

We determine the relation amongst the global Lê cycles and the Milnor classes of analytic hypersurfaces defined by a section of a very ample line bundle over a compact complex manifold. The key point is finding appropriate expressions for the global Lê cycles and for the Milnor classes in terms of polar varieties. Our starting points are an interpretation of the Lê cycles given by T. Gaffney and R. Gassler, a formula by A. Parusinski and P. Pragacz for the Milnor classes via McPherson’s functor, and a conjecture of J.-P. Brasselet, that we prove, stating that Milnor classes can be expressed in terms of polar varieties. We then use the work by R. Piegne for Mather classes, by J. Schürmann and M. Tibăr for MacPherson’s classes for constructible functions, and by D. Massey for an extension of the local Lê cycles for constructible sheaves.

Geometrical coupling fields of a hypercomplex type

This paper presents an application of Laplace's equation obtained from a quaternionic function that satisfies the Cauchy-Riemann conditions determined earlier by Borges and Machado [#!BorgesZeMarcio!#]. Therefore, we show that it is possible to express in a single equation gravity, electric and magnetic potential fields, and this expression can only be provided due to a function that will be called here the coupling function.

Geometrical hypercomplex coupling between electric and gravitational fields

The present work shows a coupling of electrical and gravitational fields through Cauchy-Riemann conditions for quaternions present in a previous paper [1]. It is also obtained an extended version of the Laplace-like equations for quaternions, now written in terms of both electric and gravitational fields.
