2. Removal of calcium hydroxide from Weine Type II systems using photon-induced photoacoustic streaming, passive ultrasonic, and needle irrigation: a microcomputed tomography study
ABSTRACT Objective This study compared the effectiveness of Er:YAG laser-activated irrigation (PIPS), passive ultrasonic irrigation (PUI) with EndoUltra and standard needle irrigation (SNI) in the removal of calcium hydroxide [Ca(OH)2] from the mesial roots of Weine Type II mandibular molars. Material and Methods Thirty mandibular molars were screened by

3. Análise de desempenho no uso de pré-busca para distribuição de vídeo sobre redes P2P
Peer-to-Peer Video on Demand Systems have well stabilished its importance in recent years. Such consolidation is due to the high gains that may be archieved in terms savings in transmission bandwidth of the servers. In this work, we evaluate how this technology can enhance the gains for the transmission of continuous media over the Internet. To achieve this

4. Comparação analítica dos esquemas de autenticação em sistemas P2P de live streaming / Comparative analisys of authentication schemes in P2P live streaming
P2P live streaming applications have great potential for improvements in terms of popularity as well as quality. However, they are subject to pollution attacks, in which a malicious user tampers with audio/video of streams in order to trick other users. The authentication of blocks in a stream allows the detection of pollution in received content and can lea

9. Higher plant myosin XI moves processively on actin with 35 nm steps at high velocity
High velocity cytoplasmic streaming is found in various plant cells from algae to angiosperms. We characterized mechanical and enzymatic properties of a higher plant myosin purified from tobacco bright yellow-2 cells, responsible for cytoplasmic streaming, having a 175 kDa heavy chain and calmodulin light chains. Sequence analysis shows it to be a class XI

10. Effect of the Specific Toxin in Helminthosporium victoriae on Host Cell Membranes 1
Helminthosporium victoriae toxin, which affects only hosts of the toxin-producing fungus, causes loss of electrolytes from roots, leaves, and coleoptiles of treated plants. Root hair cells lost the ability to plasmolyze after 20 minutes exposure to toxin in solution; comparable resistant cells retained plasmolytic ability during 3 hours exposure. Toxin stopp

11. The metabolic implications of intracellular circulation
Two views currently dominate research into cell function and regulation. Model I assumes that cell behavior is quite similar to that expected for a watery bag of enzymes and ligands. Model II assumes that three-dimensional order and structure constrain and determine metabolite behavior. A major problem in cell metabolism is determining why essentially a
