Here, we document in-vivo bite forces recorded from wild piranhas. Integrating this empirical data with allometry, bite simulations, and FEA, we have reconstructed the bite capabilities and potential feeding ecology of the extinct giant Miocene piranha, Megapiranha paranensis. An anterior bite force of 320 N from the black piranha, Serrasalmus rhombeus, is the strongest bite force recorded for ...

Pyrolysis and/or piranha treatment of fluorinated /ozonated single-walled carbon nanotubes (SWNTs) were found to have cut the nanotubes to short length (~100nm). Pyrolysis of partially fluorinated SWNTs (~C5F) at 700°C cut the nanotubes without causing significant crosslinking among the SWNTs. When pyrolyzed at lower temperatures, the fluorinated SWNTs need room temperature piranha treatment to...

Under \adaptive parallelism," the set of processors executing a parallel program may grow or shrink as the program runs. Potential gains include the capacity to run a parallel program on the idle workstations in a conventional LAN|processors join the computation when they become idle, and withdraw when their owners need them|and to manage the nodes of a dedicated multiprocessor eeciency. Experi...

An elegant new study has correlated the generation of sound patterns in the red-bellied piranha (Pygocentrus nattereri) with three distinct behaviours.

A two-step process is utilized for cutting single-walled carbon nanotubes (SWNTs). The first step requires the breakage of carbon-carbon bonds in the lattice while the second step is aimed at etching at these damage sites to create short, cut nanotubes. To achieve monodisperse lengths from any cutting strategy requires control of both steps. Room-temperature piranha and ammonium persulfate solu...

Cluster computing has emerged as a key parallel processing platform for large scale data. All major internet companies use it as their major central processing platform. One of cluster computing’s most popular examples is MapReduce and its open source implementation Hadoop. These systems were originally designed for batch and massive-scale computations. Interestingly, over time their production...

Red-bellied piranhas (Pygocentrus nattereri) are widely caught with different intensities throughout the region of Solimões-Amazonas River by local fishermen. Thus, the management of this resource is performed in the absence of any information on its genetic stock. P. nattereri is a voracious predator and widely distributed in the Neotropical region, and it is found in other regions of American...

O presente artigo, com base na proposta teórico-analítica da Análise Materialista de Discurso, apresenta uma reflexão sobre a violência doméstica partir relatos-testemunho mulheres que sofreram essa violência. Os relatos foram publicados pelo coletivo Filhas Frida através campanha Ajudem Aquela, qual teve o objetivo conscientizar os efeitos contra no âmbito doméstico. A descrição e interpretaçã...

Piranha solution is a highly acidic mixture of sulfuric acid and hydrogen peroxide. The present study aimed at developing dimensionally stable anode (DSA), made titanium metal foil coated with Ruthenium Dioxide (RuO2), for the electrochemical oxidation peroxide in presence strong under ambient conditions. Results showed that piranha was fully degraded 5 h constant current 2 A (or density 0.32 A...

In this paper, we investigate the load balancing problem among a cluster of mobile and fixed devices in a voice enabled interface. We consider a design approach. The voice interface has to support up to a hundred simultaneous users. The load balancing criteria we consider are defined, on the one hand in terms of network, CPU and memory resources, and on the other hand in terms of the boundary b...
