1. Tunnel vision in current chemicals management cannot deal with the unknown risk of synthetic chemicals in aquatic systems
Resumo A gestão e o manejo de poluentes químicos são focados na periculosidade, exposição e avaliação de risco. Esse processo é lento e não acompanha o surgimento de novas substâncias e o desenvolvimento do seu uso. O monitoramento ambiental foca em poucas substâncias que são bem conhecidas. Consequentemente, a maioria das substâncias emitidas

2. Unknown Unknowns in Innovative Projects: Early Signs Sensemaking
Abstract This study aims to understand early signs’ sensemaking relevance to identifying unknown unknowns on innovative projects. When managing these projects, early signs of changes in the environment, combined with a sensemaking process, can help identify them prior to their occurrence and mitigate unwanted effects of these uncertainties. To this end, we

3. INFLUÊNCIA DA EXPERIÊNCIA DOS GESTORES NA BUSCA DE INFORMAÇÃO SOBRE UNK UNKS EM PROJETOS
RESUMO Objetivo: Compreender se os gestores mais experientes incorrem na falácia da centralidade, negligenciando a busca de informação sobre os unknown unknowns em projetos inovadores para dar sentido (sensemaking) ao que ocorre no contexto do projeto. Originalidade/lacuna/relevância/implicações: A falácia da centralidade, teoria formulada por Westr

4. Efeitos da formação de classes de equivalência sobre a solução de problemas de adição e subtração / Some effects of equivalence class formation over the solution of addition and subtraction problems
Research has shown that some properties of the additive problem may cause difficulties to solve it. The most important are: the problems presentation form, the semantic structure and the position of the unknown. Two experiments were conducted with some methodological differences, but both with the aim of investigating if the formation of an equivalence class

5. Criando sentido para as incertezas imprevisíveis em projetos inovadores / Sensemaking unforeseeable uncertainty for innovative projects
As inovações, motores do desenvolvimento global, viabilizam-se nas organizações por meio dos projetos. Quanto maior for o nível de inovação nesses projetos, maior é a probabilidade de existirem incertezas imprevisíveis. A identificação dos sinais precoces de uma mudança permitiria perceber essas incertezas, porém, para o reconhecimento antecipad

6. SuperaÃÃo de dormÃncia de diÃsporos de cajazeira (Spondias mombin L.). / Hog plum tree (Spondias mombin L.)endocarps dormancy eakage.
The hog plum tree appear as one most promising fruit tree for the cultivation in commercial scale, due to its excellent adaptation to the agro-ecological conditions of the Brazilian Northeaste, especially, under semi-arid ecosystem and its high socioeconomic potential. Therefore, it is necessary its domestication, which is quite hindered due to propagation p

7. ‘Conserved hypothetical’ proteins: prioritization of targets for experimental study
Comparative genomics shows that a substantial fraction of the genes in sequenced genomes encodes ‘conserved hypothetical’ proteins, i.e. those that are found in organisms from several phylogenetic lineages but have not been functionally characterized. Here, we briefly discuss recent progress in functional characterization of prokaryotic ‘conserved hypo

8. A Bayesian Approach to Detect Quantitative Trait Loci Using Markov Chain Monte Carlo
Markov chain Monte Carlo (MCMC) techniques are applied to simultaneously identify multiple quantitative trait loci (QTL) and the magnitude of their effects. Using a Bayesian approach a multi-locus model is fit to quantitative trait and molecular marker data, instead of fitting one locus at a time. The phenotypic trait is modeled as a linear function of the a

9. Epidemiological Fingerprinting of Pseudomonas aeruginosa by the Production of and Sensitivity to Pyocin and Bacteriophage1
A new method has been devised to trace cross-infection by Pseudomonas aeruginosa. Unknown strains growing logarithmically in liquid media were treated with mitomycin C to induce the liberation of pyocin and phage. The lysates were then tested against 27 selected indicator strains, and the zones of clearing were differentiated as to killing by pyocin or lysis

10. Identification of Genes Required for Embryo Development in Arabidopsis1[w]
A long-term goal of Arabidopsis research is to define the minimal gene set needed to produce a viable plant with a normal phenotype under diverse conditions. This will require both forward and reverse genetics along with novel strategies to characterize multigene families and redundant biochemical pathways. Here we describe an initial dataset of 250 EMB gene

11. Identification of phosphatidylserylglutamate: a novel minor lipid in Escherichia coli
Advances in mass spectrometry have facilitated the identification of novel lipid structures. In this work, we fractionated the lipids of Escherichia coli B and analyzed the fractions using negative-ion electrospray ionization mass spectrometry to reveal unknown lipid structures. Analysis of a fraction eluting with high salt from DEAE cellulose revealed a ser

12. Methods To Increase Fidelity of Repetitive Extragenic Palindromic PCR Fingerprint-Based Bacterial Source Tracking Efforts
The goal of the study was to determine which similarity coefficient and statistical method to use to produce the highest rate of correct assignment (RCA) in repetitive extragenic palindromic PCR-based bacterial source tracking. In addition, the use of standards for deciding whether to accept or reject source assignments was investigated. The use of curve-bas
