Porque é que os estudos prisionais não explicam fenómenos notórios como a violência institucional nos lugares com mais segurança do mundo, muito diferente criminalização dos sexos e das classes sociais, as intenções declaradas incumpridas pelos estados de respeito direitos humanos? que, este respeito, dominam preconceitos ideológicos? As penas penitenciárias são modernos, par trabalho assalaria...

Sacrificial layer electrophoretic deposition (SLED) is a technique to assemble nanoparticles that yields free-standing, multilayered nanoparticle films with macroscopic lateral dimensions after the sacrificial layer is dissolved.

Aluminum anodes have been widely used in the cathodic protection of marine structures. However there are conditions in which these anodes become passivated or face some localized or unwanted corrosion, which influences their efficiency. Addition of alloying elements such as Zn and In not only have improved the efficiency of the anodes but also the effect of casting parameters such as ultra ...

The cost of microalgae harvesting constitutes a heavy burden on the commercialization biofuel production. present study addressed this problem through economic and parametric comparison electrochemical using sacrificial electrode (aluminum) nonsacrificial (graphite). efficiency, power consumption, operation were collected as objective variables function applied current initial pH solution. resu...

The requirements of the rules and regulations Classification Societies are based on assumption that during construction operation ships hull corrosion protection measures implemented according to standards other regulatory documents currently in force. For purposes designing ship structures, load components for different types have been obtained paper. There collected data relationship between ...

In MEMS fabrication micro-mechanical components have to be partially released from a substrate. Selectively etching away sacrificial layers, such that a free standing structure remains, is a widely used technique for this purpose. Free standing structures allow MEMS devices to induce or to sense mechanical movements or vibrations. During sacrificial etching lower etch rates than the blanket one...
