O fazendeiro do Brazil :cultivador melhorado na economia rural dos generos já cultivados, e de outros, que se podem introduzir ; e nas fabricas, que lhe são proprias, segundo o melhor, que se tem escrito a este assumpto : debaixo dos auspicios, e de ordem de sua Alteza Real o Principe Regente, Nosso Senhor colligido de memorias estrangeiras

José Mariano da Conceição Velloso, 172?-1811 - Frei Velloso teve duas grandes paixões: a botânica e o desenho, inclusive a gravura e a pintura. Esforça-se para difundir o desenho e a pintura pela sua oficina do Arco do Cego. Trabalha na produção de livros didáticos, num esforço gigantesco, produz obras relacionadas com a agricultura, a mineração, a pecuária e as artes que se podiam obter àquela época. Como relata Borba de Moraes, o esforço fracassou devido ao imenso atraso das elites brasileiras da época. A respeito do Fazendeiro do Brasil, o Governador de São Paulo informou à Corte que não conseguira vender um só exemplar da coleção e que não achava quem os quisesse levar de graça.

Nuevas fórmulas publicitarias: los advergames como herramienta de las comunicaciones de marketing

Los advergames son videojuegos orientados a la comunicación publicitaria. Su naturaleza de mensaje híbrido, al combinar contenido publicitario y contenido de entretenimiento, aporta interesantes posibilidades al desarrollo de comunicaciones de marketing en un entorno mediático en el que la publicidad tradicional ha ido perdiendo eficacia. El presente artículo delimita el concepto de advergame, analizando las diferentes tipologías existentes y sus efectos sobre diversos objetivos de marketing y de comunicación. Asimismo, se apuntan algunas recomendaciones a la hora de desarrollar comunicaciones de marketing mediante advergames, así como las cuestiones éticas y morales que deben considerarse

Factores explicativos de la intención de emprender en la mujer. Aspectos diferenciales en la población universitaria según la variable género

El objetivo del presente trabajo de investigación es arrojar luz sobre los factores que explican la menor intencionalidad en la población femenina para involucrarse en procesos de creación de empresas. Para ello, se ha desarrollado un modelo de ecuaciones estructurales que identifica un conjunto de variables que permiten explicar la intención de emprender en la población potencialmente emprendedora. La validación del modelo se ha realizado mediante una encuesta realizada a 1222 estudiantes de 12 titulaciones diferentes de la Universidad de Málaga. La aplicación del modelo a las poblaciones masculina y femenina ha permitido apreciar diferencias significativas en los patrones de comportamiento en función del género, identificando un proceso más complejo y necesitado de apoyo externo en la población femenina con respecto a la masculina.

Fine mapping and functional analysis of the multiple sclerosis risk gene CD6

CD6 has recently been identified and validated as risk gene for multiple sclerosis (MS), based on the association of a single nucleotide polymorphism (SNP), rs17824933, located in intron 1. CD6 is a cell surface scavenger receptor involved in T-cell activation and proliferation, as well as in thymocyte differentiation. In this study, we performed a haptag SNP screen of the CD6 gene locus using a total of thirteen tagging SNPs, of which three were non-synonymous SNPs, and replicated the recently reported GWAS SNP rs650258 in a Spanish-Basque collection of 814 controls and 823 cases. Validation of the six most strongly associated SNPs was performed in an independent collection of 2265 MS patients and 2600 healthy controls. We identified association of haplotypes composed of two non-synonymous SNPs [rs11230563 (R225W) and rs2074225 (A257V)] in the 2nd SRCR domain with susceptibility to MS (Pmax(T) permutation=161024). The effect of these haplotypes on CD6 surface expression and cytokine secretion was also tested. The analysis showed significantly different CD6 expression patterns in the distinct cell subsets, i.e. – CD4+ naı¨ve cells, P = 0.0001; CD8+ naı¨ve cells, P,0.0001; CD4+ and CD8+ central memory cells, P = 0.01 and 0.05, respectively; and natural killer T (NKT) cells, P = 0.02; with the protective haplotype (RA) showing higher expression of CD6. However, no significant changes were observed in natural killer (NK) cells, effector memory and terminally differentiated effector memory T cells. Our findings reveal that this new MS-associated CD6 risk haplotype significantly modifies expression of CD6 on CD4+ and CD8+ T cells.

Radiotherapy plus nimotuzumab or placebo in the treatment of high grade glioma patients: results from a randomized, double blind trial

Background The prognosis of patients bearing high grade glioma remains dismal. Epidermal Growth Factor Receptor (EGFR) is well validated as a primary contributor of glioma initiation and progression. Nimotuzumab is a humanized monoclonal antibody that recognizes the EGFR extracellular domain and reaches Central Nervous System tumors, in nonclinical and clinical setting. While it has similar activity when compared to other anti-EGFR antibodies, it does not induce skin toxicity or hypomagnesemia. Methods A randomized, double blind, multicentric clinical trial was conducted in high grade glioma patients (41 anaplastic astrocytoma and 29 glioblastoma multiforme) that received radiotherapy plus nimotuzumab or placebo. Treatment and placebo groups were well-balanced for the most important prognostic variables. Patients received 6 weekly doses of 200 mg nimotuzumab or placebo together with irradiation as induction therapy. Maintenance treatment was given for 1 year with subsequent doses administered every 3 weeks. The objectives of this study were to assess the comparative overall survival, progression free survival, response rate, immunogenicity and safety. Results The median cumulative dose was 3200 mg of nimotuzumab given over a median number of 16 doses. The combination of nimotuzumab and RT was well-tolerated. The most prevalent related adverse reactions included nausea, fever, tremors, anorexia and hepatic test alteration. No anti-idiotypic response was detected, confirming the antibody low immunogenicity. The mean and median survival time for subjects treated with nimotuzumab was 31.06 and 17.76 vs. 21.07 and 12.63 months for the control group. Conclusions In this randomized trial, nimotuzumab showed an excellent safety profile and significant survival benefit in combination with irradiation.

Deducção chronologica dos fatos mais notaveis da historia do Brasil

Galeria dos brasileiros illustres (os contemporaneos) : retratos dos homens mais illustres do Brasil na politica, sciencias e letras, desde a guerra da independencia até os nossos dias : copiados do natural e lithographados por S.A. Sisson, acompanhados das suas respectivas biographias, publicada sob a protecção de sua Magestade o Imperador

Galeria dos brasileiros illustres traz retratos copiados do natural e litografados das principais figuras brasileiras da política, ciências e letras, com biografias redigidas por diversos escritos da época, por alguns dos próprios biografados ou por membros de suas famílias. Considerada a mais importante de Sisson, esta obra teve tiragem reduzida e muitos exemplares foram desmanchados por antiquários que emolduravam os retratos, vendendo-os por alto preço. Segundo Borba de Moraes, "é muito difícil encontrar-se hoje em dia um exemplar perfeito e em boas condições" e que "só muito raramente aparece um exemplar à venda."

Design of an optimised wheel profile for rail vehicles operating on two track gauges

This paper sets out an optimum synthesis methodology for wheel profiles of railway vehicles in order to secure good dynamic behaviour with different track configurations. Specifically, the optimisation process has been applied to the case of rail wheelsets mounted on double gauge bogies, that move over two different gauges, which also have different types of rail: the Iberian gauge (1668 mm) and the UIC gauge (1435 mm). Optimisation is performed using Genetic Algorithms and traditional optimisation methods in a complementary way. The objective function used is based on an ideal equivalent conicity curve which ensures good stability on straight sections and also proper negotiation of curves. To this end the curve is constructed in such a way that it is constant with a low value for small lateral wheelset displacements (with regard to stability), and increases as the displacements increase (to facilitate negotiation of curved sections). Using this kind of ideal conicity curve also enables a wheel profile to be secured where the contact points have a larger distribution over the active contact areas, making wear more homogeneous and reducing stresses. The result is a wheel profile with a conicity that is closer to the target conicity for both gauges studied, producing better curve negotiation while maintaining good stability on straight sections of track. The paper shows the resultant wheel profile, the contact curves it produces, and a number of dynamic analyses demonstrating better dynamic behaviour of the synthesised wheel on curved sections with respect to the original wheel.
