1. Modelagem no ensino de Física via produção de stop motion, com o computador Raspberry Pi
Resumo Neste trabalho apresentamos um aparato de baixo custo para produção de animações quadro a quadro (stop motion) como ferramenta didática no ensino da Física. Dedicado à captura e exibição de stop motions, o aparato é construído com o computador Raspberry Pi e conta com uma interface que permite ao aluno um manuseio simplificado e reproduçã

2. Panorama e proposições da animação em stop motion / Panorama and propositions of stop motion animation
O principal objetivo desta pesquisa é estabelecer o panorama atual da animação mundial com ênfase na técnica de animação conhecida como stop motion. Para isso, foi realizado um levantamento dos principais filmes de animação produzidos entre 1999 e 2008, para em seguida, promover uma discussão a respeito da utilização desta técnica e das principa

4. O conceito de violência de professoras do ensino fundamental.
The main objective of this study is to describe the concept of violence of a social group made up of fundamental school teachers belonging to public and private schools. In order to address different description levels, the following categories were established: class, modality and form of violence. In order to contextualize the conceptualized violence, its

5. Stop-and-Go Movements of Plant Golgi Stacks Are Mediated by the Acto-Myosin System1
The Golgi apparatus in plant cells consists of a large number of independent Golgi stack/trans-Golgi network/Golgi matrix units that appear to be randomly distributed throughout the cytoplasm. To study the dynamic behavior of these Golgi units in living plant cells, we have cloned a cDNA from soybean (Glycine max), GmMan1, encoding the resident Golgi protein

6. The nature of rhodopsin-triggered photocurrents in Chlamydomonas. I. Kinetics and influence of divalent ions.
In the green alga Chlamydomonas chlamyrhodopsin fulfills its role as a light sensor by absorbing light and activating photoreceptor channels within the eyespot area. At intense light stimuli, the photoreceptor (P) current triggers a fast and a slow flagellar current that finally leads to backward swimming (stop response). Here we report about probing the pho

7. Stopping the circadian pacemaker with inhibitors of protein synthesis.
The requirement for protein synthesis in the mechanism of a circadian pacemaker was investigated by using inhibitors of protein synthesis. Continuous treatment of the ocular circadian pacemaker of the mollusc Bulla gouldiana with anisomycin or cycloheximide substantially lengthened (up to 39 and 52 hr, respectively) the free-running period of the rhythm. To

8. Cryobaroenzymic studies as a tool for investigating activated complexes: creatine kinase.ADP.Mg.nitrate.creatine as a model.
By combining cryoenzymology with baroenzymology (a technique we term "cryobaroenzymology") one can obtain "stop-action" pictures of the intermediates in an enzyme reaction pathway and then observe their structural and energetic features ("motion features"). We illustrate the potential of this approach by considering the formation of a transient state analogu

9. Rhizobium meliloti swims by unidirectional, intermittent rotation of right-handed flagellar helices.
The 5 to 10 peritrichously inserted complex flagella of Rhizobium meliloti MVII-1 were found to form right-handed flagellar bundles. Bacteria swam at speeds up to 60 microns/s, their random three-dimensional walk consisting of straight runs and quick directional changes (turns) without the vigorous angular motion (tumbling) seen in swimming Escherichia coli

10. Exact solution of a jamming transition: Closed equations for a bootstrap percolation problem
Jamming, or dynamical arrest, is a transition at which many particles stop moving in a collective manner. In nature it is brought about by, for example, increasing the packing density, changing the interactions between particles, or otherwise restricting the local motion of the elements of the system. The onset of collectivity occurs because, when one partic

11. Chemotaxis in a gliding bacterium
Myxococcus xanthus cells exhibit directed motility up phosphatidylethanolamine (PE) gradients, and we suggest that PE behaves as a chemoattractant. Computer-assisted stop-motion digital microscopy was used to record cell movements in slide culture. PE decreased cellular reversal frequency with molecular specificity that was correlated with the fatty acid com

12. Color-Sensitive Motility and Methanol Release Responses in Rhodobacter sphaeroides
Blue-light-induced repellent and demethylation responses, characteristic of behavioral adaptation, were observed in Rhodobacter sphaeroides. They were analyzed by computer-assisted motion analysis and through the release of volatile tritiated compounds from [methyl-3H]methionine-labeled cells, respectively. Increases in the stop frequency and the rate of met
