Acclimatization of Tapeinochilos ananassae plantlets in association with arbuscular mycorrhizal fungi.

The objective of this work was to assess the potential of three isolates of arbuscular mycorrhizal fungi to promote growth of micropropagated plantlets of Tapeinochilos ananassae during acclimatization. The experiment was carried out in greenhouse, in a completely randomized block design, with four inoculation treatments: non-inoculated control and plants inoculated with Glomus etunicatum, Acaulospora longula or Gigaspora albida, with ten replicates. After 90 days, the following parameters were evaluated: survival rate, height, leaf and tiller number, leaf area, fresh and dry biomass, contents of macro- and micronutrients in the root and shoot, glomerospore number, and mycorrhizal colonization. The survival percentage was 100%, except for plants inoculated with G. albida (80%). The isolate G. etunicatum is more suitable for plant development, since it improves survival, growth, dry matter production, nutritional status, and vigor of T. ananassae micropropagated plants

O objetivo do trabalho foi avaliar o potencial de FMA e RPCP, isolados e/ou combinados (em dupla inoculação) na aclimatização de Z. spectabi/e

Ensino de ciências para deficientes auditivos: um estudo sobre a produção de narrativas em classes regulares inclusivas

The education of deaf people in regular schools is a challenge because for a long time not given due importance to their way of communication, sign language. With the inclusion of the deaf students have been put into the regular school and there is a need for a new agent on vital for their integration, the interpreter of Brazilian sign language (libras). The aim ofthis study is to analyze the narratives production by libras interpreters and science teachers in the inclusive classroom. The investigation of this issue brings the discussion questions as: what is the role of the educational interpreter? What is prescribed and what is real in the process of inclusion? The methodological approach adopted is based on Zabalza that uses the class diaries as research instruments, where the subject is searched without being noticed. The results point to a lack of knowledge of language constituted the main dilemma in the education of the deaf. Keywords: inclusive education, science education, deafnes

Maximum Cut on Interval Graphs of Interval Count Four Is NP-Complete

The computational complexity of the MaxCut problem restricted to interval graphs has been open since the 80's, being one of the problems proposed by Johnson on his Ongoing Guide to NP-completeness, and has been settled as NP-complete only recently by Adhikary, Bose, Mukherjee and Roy. On the other hand, many flawed proofs of polynomiality for MaxCut on the more restrictive class of unit/proper interval graphs (or graphs with interval count 1) have been presented along the years, and the classification of the problem is still unknown. In this paper, we present the first NP-completeness proof for MaxCut when restricted to interval graphs with bounded interval count, namely graphs with interval count 4

Cálculo de graus-dia acumulados para subsidiar ações de gerenciamento de risco de pragas.

O presente trabalho teve por objetivo apresentar as operações de um dos métodos de cálculo de graus-dia acumulados (vulgarmente conhecido como ?método do retângulo?), através de dois exemplos, um para um inseto e o outro para um nematóide, em localidade com disponibilidade de dados necessários ao cálculo de graus-dia.2.
