Ancorada na abordagem Histórico Cultural como referencial teórico, a pesquisa baseia-se em estudo de caso e representa uma investigação qualitativa cujo objetivo geral é discutir acerca das possibilidades e limites da contribuição do Programa Sala de Leitura para a formação de leitores no contexto escolar. O escolhido para a aplicação da pesquisa foi a sala de leitura Clarisse Lispector, sediada na Escola Estadual Professora Djanira Velho, escola pública do município de Ribeirão Preto e vinculada à Secretaria de Educação do Estado de São Paulo. A coleta de dados foi efetuada através de entrevista semiestruturada e interações via grupo focal, realizadas, respectivamente, com a mediadora da sala de leitura e com os sete alunos integrantes da amostra. O trabalho dialoga com outras abordagens que contemplam os estudos sobre a leitura e suas práticas; contextualiza o Programa Sala de Leitura perante as principais políticas públicas brasileiras vinculadas à formação de leitores; averigua o processo de formação do acervo e a organização do espaço da sala de leitura; analisa o processo de escolha do professor responsável pelo Programa Sala de Leitura, bem como as orientações oficiais que guiam sua prática; caracteriza as relações dos educandos com o acervo, o espaço, a professora mediadora e as práticas de leitura; identifica e descreve as práticas que ocorrem na sala de leitura. Os resultados apontam que, embora haja rejeição dos educandos para com as obras pertencentes ao acervo, o espaço, a presença de uma professora e o envolvimento em práticas de leitura são declarados positivos para a formação leitora dos educandos da amostra. Além disso, reconhece as potencialidades da sala de leitura na formação leitora dos educandos e aponta os limites a serem superados mediante sugestões que se apoiam na diversificação do acervo, na oferta de momentos de leitura livre e, principalmente, no ensino de estratégias de leitura nas práticas de letramento literário Based in the Cultural Historical approach as a theoretical framework, the research is based in a case study and represents a qualitative investigation which its general objective is to discuss the possibilities and limits of the contribution of the Reading classroom program into forming readers in the school context. The place chosen to develop the research was the reading class Clarice Lispector, at the Escola Estadual Professora Djanira Velho, a public school in the city of Ribeirão Preto and linked to the São Paulo State Department of Education. The data collection was performed through a semi-structures interview and interactions via focus group, carried out, respectively, with the reading classroom mediator and the seven sample students. The research dialogues with other approaches that include studies about reading and its practices; contextualizes the Reading Classroom Program before the main public policies linked to the formation of readers; ascertain the process of formation of the book collection and the organization of the space of the reading classroom; analyzes the process of choosing the teacher responsible for the Reading Classroom Program, as well as the official guidelines that guide their practice; characterizes the students relations with the book collection, the space, the mediator teacher and the reading practices; identifies and describes the practices that occur in the reading classroom. The results indicate that, although there is rejection of the students to the books that belong to the collection, the space, the presence of a teacher and the involvement in reading practices are declared positive for the reading education of the sample students. In addition, it recognizes the potential of the reading classroom in reading education of the students and points out the limits to be overcome through suggestions that support diversification of the book collection, the offer of free reading moments and, most importantly, the teaching of reading strategies in literary literacy practices

Plants exhibit respiratory bypasses (e.g., the alternative oxidase [AOX]) and increase the synthesis of carboxylates in their organs (leaves and roots) in response to phosphorus (P) deficiency, which increases P uptake capacity. They also show differential expression of high-affinity inorganic phosphorus (Pi) transporters, thus avoiding P toxicity at a high P availability. The association between AOX and carboxylate synthesis was tested in Solanum lycopersicum plants grown at different soil P availability, by using plants grown under P-sufficient and P-limiting conditions and by applying a short-term (24 hr) P-sufficient pulse to plants grown under P limitation. Tests were also performed with plants colonized with arbuscular mycorrhizal fungi, which increased plant P concentration under reduced P availability. The in vivo activities of AOX and cytochrome oxidase were measured together with the concentration of carboxylates and the P concentration in plant organs. Gene transcription of Pi transporters (LePT1 and LePT2) was also studied. A coordinated response between plant P concentration with these traits was observed, indicating that a sufficient P availability in soil led to a suppression of both AOX activity and synthesis of citrate and a downregulation of the transcription of genes encoding high-affinity Pi transporters, presumably to avoid P toxicity., This work was financed by the MICINN—Projects BFU2011‐23294 and CTM2014‐53902‐C2‐1‐P.

Immature, vegetable-like fruits are produced by crops of great economic importance, including cucumbers, zucchini, eggplants and bell peppers, among others. Because of their high respiration rates, associated with high rates of dehydration and metabolism, and their susceptibility to chilling injury (CI), vegetable fruits are highly perishable commodities, requiring particular storage conditions to avoid postharvest losses. This review focuses on the oxidative stress that affects the postharvest quality of vegetable fruits under chilling storage. We define the physiological and biochemical factors that are associated with the oxidative stress and the development of CI symptoms in these commodities, and discuss the different physical, chemical and biotechnological approaches that have been proposed to reduce oxidative stress while enhancing the chilling tolerance of vegetable fruits.

This paper presents a method to estimate electrical parameters in a three-phase induction motor (MIT) equivalent circuit, using genetic algorithm (GA). This method is applied in a MATLAB® Simulink environment. The methodology consist in minimize objective function to represent the estimated current error with GA. The stator current versus slip curve is a simulation result and it will be used to estimate electrical parameters of equivalent circuit. In this work two different theory MIT model are considered Chapman[1] and Wildi [2]. The goal is define the better current versus slip estimate curve for each model and to determine which one has the best motor simulate representation.
