Eletrificação e crescimento industrial no estado de São Paulo: 1880-1940

O objetivo deste trabalho é evidenciar a existência de relações entre progresso técnico e desenvolvimento econômico no processo de formação da economia brasileira. Em seu aspecto mais específico, refere-se ao estudo do desenvolvimento da eletrificação e seus efeitos sobre o crescimento industrial no Estado de São Paulo, no período compreendido entre as duas décadas finais do século passado até a década de 1930. Durante este período - quando a economia e a sociedade brasileiras se transformam pelo desenvolvimento de relações de produção de natureza capitalista, ocorridas a partir do fim do escravismo, da introdução do trabalho assalariado, da expansão cafeeira, do aparecimento da ferrovia e dos bancos, das primeiras indústrias e, enfim, de atividades voltadas ao desenvolvimento do mercado interno - , o desenvolvimento da eletrificação e, especialmente, o uso de força motriz elétrica na indústria constituíram transformações essenciais. A o provocarem alterações irrevogáveis na base técnica da indústria contribuíram, também, para a alteração do padrão de acumulação.

Trajetórias de assentamentos rurais: experiências em balanço

Este trabalho tem como objetivo avaliar o complexo processo de constituição de oito experências de assentamentos rurais, no tocante ao seu desenvolvimento econômico e político-organizacional, localizados em regiões distintas do Estado de São Paulo. Trajetórias diferenciadas entre si marcam essas experiências, os aspectos organizacionais incidem de forma diferenciada sobre a evolução econômica, não havendo uma relação de causalidade entre desempenho econômico, existência de dissensões e alternativas de organização. Pulverização e competição são fatores presentes na tentativa de construção de um novo modo de vida. Constata-se significativa pressão para que esses novos agricultores se mtegrem ao complexo agroindustnal e ao processo de globalização econômica hoje em curso.

O mito nas Heróides de Ovídio: epístola I (De Penélope a Ulisses)

The objective of this work is to carry out a study about some aspects of the myth in the book Heroides, written by the Latin author Ovid (43 b.C. – 17/18 A.D.). To do so, this study will focus on the Letter I (“From Penelope to Ulysses”) approaching not only the stylistic issues of the elegiac genre, but also, studying them in connection with the epistolary subgenre. Departing from some biographical remarks about the author and from studies made by scholars about this poet, this work seeks to address the myth and certain little explored features of this genre, as the use of rhetoric

A construção do projeto político-pedagógico das escolas do campo do município de Araraquara

This study aimed to analyze the process of developing and implementing a politicalpedagogical project for rural schools in the city of Araraquara, focusing on one of the schools served. This is an ethnographic qualitative study. The instruments of data collection were participant observation, semi-structured interviews and documentary analysis. It was observed are a change in the community organization throughout the process, with regard to a more active attitude on the part of its members, who have pursued other means to claim the fulfillment of their demands by the Government and relevant institutions, which points to the pedagogical character of participation in the movement to fight for the education they desire. It was also noticed a process of re-signification by the subjects, of their own community identity while seated in an agrarian reform project, as well as a more effective participation of those in everyday life and school organization. It was also observed changes in indicators of school, with an increase in the achievement of students as well as reducing the dropout rate to zero, and the reduction of absenteeism of teachers.

Luminous efficiency enhancement of PVK based OLEDs with fac-[ClRe(CO)(3)(bpy)]

The luminous efficiency of organic light-emitting diodes based on poly(N-vinylcarbazole), PVK, was improved by adding fac-[ClRe(CO)(3)(bpy)], bpy = 2,2`-bipyridine, to PVK host. Emissive layers with various Re(I) complex/host ratio were employed and optoelectronic properties were compared with the single PVK device. The single PVK device exhibits a characteristic electroluminescence with blue emission, lambda(max) 420 nm, assigned to the PVK excimer. On the other hand, the intense and broad band at lambda(max) 580 nm of the Re(I) complex/PVK OLEDs is ascribed to the metal-to-ligand charge transfer excited state emission of fac-[ClRe(CO)(3)(bpy)]. At 30 V, the device luminous efficiency increased from 16 mcd/A for the single PVK device to 211 mcd/A for the 11% (w/w) Re(I) complex/PVK OLED, in which fac-[ClRe(CO)(3)(bpy)] acts as an electron-trap in PVK films. The device current is space-charge limited and exhibits typical emissive layer thickness dependence. (C) 2011 Elsevier B.V. All rights reserved.

The effect of intrathecal gabapentin on neuropathic pain is independent of the integrity of the dorsolateral funiculus in rats

Aim: This study evaluates the contribution of inhibitory pain pathways that descend to the spinal cord through the dorsolateral funiculus (DLF) on the effect of intrathecal gabapentin against spinal nerve ligation (SNL)-induced behavioral hypersensitivity to mechanical stimulation in rats. Main method: Rats were submitted to a sham or complete ligation of the right LS and L6 spinal nerves and a sham or complete DLF lesion. Next, the changes induced by intrathecal administration of gabapentin on the paw withdrawal threshold of rats to mechanical stimulation were evaluated electronically. Key findings: Intrathecal gabapentin (200 mu g/5 mu l) that was injected 2 or 7 days after surgery fully inhibited the SNL-induced behavioral hypersensitivity to mechanical stimulation in sham DLF-Iesioned rats; gabapentin was effective against the SNL-induced behavioral hypersensitivity to mechanical stimulation also in DLF-Iesioned rats. Significance: The effect of intrathecally administered gabapentin against SNL-induced behavioral hypersensitivity to mechanical stimulation in rats does not depend on the activation of nerve fibers that descend to the spinal cord via the DLF.

Chromosome painting in three-toed sloths: a cytogenetic signature and ancestral karyotype for Xenarthra

Background: Xenarthra (sloths, armadillos and anteaters) represent one of four currently recognized Eutherian mammal supraorders. Some phylogenomic studies point to the possibility of Xenarthra being at the base of the Eutherian tree, together or not with the supraorder Afrotheria. We performed painting with human autosomes and X-chromosome specific probes on metaphases of two three-toed sloths: Bradypus torquatus and B. variegatus. These species represent the fourth of the five extant Xenarthra families to be studied with this approach. Results: Eleven human chromosomes were conserved as one block in both B. torquatus and B. variegatus: (HSA 5, 6, 9, 11, 13, 14, 15, 17, 18, 20, 21 and the X chromosome). B. torquatus, three additional human chromosomes were conserved intact (HSA 1, 3 and 4). The remaining human chromosomes were represented by two or three segments on each sloth. Seven associations between human chromosomes were detected in the karyotypes of both B. torquatus and B. variegatus: HSA 3/21, 4/8, 7/10, 7/16, 12/22, 14/15 and 17/19. The ancestral Eutherian association 16/19 was not detected in the Bradypus species. Conclusions: Our results together with previous reports enabled us to propose a hypothetical ancestral Xenarthran karyotype with 48 chromosomes that would differ from the proposed ancestral Eutherian karyotype by the presence of the association HSA 7/10 and by the split of HSA 8 into three blocks, instead of the two found in the Eutherian ancestor. These same chromosome features point to the monophyly of Xenarthra, making this the second supraorder of placental mammals to have a chromosome signature supporting its monophyly.

Hereditary Autoinflammatory Syndromes: A Brazilian Multicenter Study

To evaluate the prevalence of genetic defects in clinically suspected autoinflammatory syndromes (AIS) in a Brazilian multicenter study. The study included 102 patients with a clinical diagnosis of Cryopyrin Associated Periodic Syndromes (CAPS), TNF Receptor Associated Periodic Syndrome (TRAPS), Familial Mediterranean Fever (FMF), Mevalonate Kinase Deficiency (MKD) and Pediatric Granulomatous Arthritis (PGA). One of the five AIS-related genes (NLRP3, TNFRSF1A, MEFV, MVK and NOD2) was evaluated in each patient by direct DNA sequencing, based on the most probable clinical suspect. Clinical diagnoses of the 102 patients were: CAPS (n = 28), TRAPS (n = 31), FMF (n = 17), MKD (n = 17) and PGA (n = 9). Of them, 27/102 (26 %) had a confirmed genetic diagnosis: 6/28 (21 %) CAPS patients, 7/31 (23 %) TRAPS, 3/17 (18 %) FMF, 3/17 (18 %) MKD and 8/9 (89 %) PGA. We have found that approximately one third of the Brazilian patients with a clinical suspicion of AIS have a confirmed genetic diagnosis.
