Recycling is an alternative for preserving historical heritage buildings. Through such process, buildings are occupied by new usages that assure they are not abandoned. However, conservation issues, like pathological manifestations by filamentous fungi, are common even in buildings receiving new uses. Thus, it is extremely important to know the microclimate behavior of these buildings and analyze if there are usages that favor the appearance of filamentous fungi or not. This study aims to verify if new usages modify the microclimate in historical buildings and if such possible change favors the appearance of pathological manifestations by filamentous fimgi in some specific use. To achieve the results, three buildings that have gone through recycling processes were chosen in the city of Pelotas, in Southernmost Brazil. The city possesses a large number of buildings with historical value and its climate conditions are propitious for appearance of filamentous fungi. For 12 months, microclimate was monitored, the environments modus operandi was characterized and there was a survey on the pathological manifestations by filamentous fungi in the three buildings with two different uses： administration offices and exhibition rooms. Conclusion was that usages that allow natural ventilation and lighting favor conservation, which is what happens in the ones used as administration offices. Besides that, it was noticed that the construction system also influences, since buildings with a high cellar that is being used did not present filamentous fungi, which also shows the influence of ascending humidity on the appearance of such pathological manifestations.

Chiral Dirac Equation Derived From Quaternionic Maxwell’s Systems

引用

Journal of Electromagnetic Analysis and Applications 2013年第3期5卷 103-108页

作者： Hector torres-silva University School of Electrical and Electronic Engineering Arica Chile.

In the present article we propose a simple equality involving the Dirac operator and the Maxwell operators under chiral approach. This equality establishes a direct connection between solutions of the two systems and moreover, we show that it is valid when the natural relation between the frequency of the electromagnetic wave and the energy of the Dirac particle is fulfilled if the electric field E is parallel to the magnetic field H. Our analysis is based on the quaternionic form of the Dirac equation and on the quaternionic form of the Maxwell equations. In both cases these reformulations are completely equivalent to the traditional form of the Dirac and Maxwell systems. This theory is a new quantum mechanics (QM) interpretation. The below research proves that the QM represents the electrodynamics of the curvilinear closed chiral waves. It is entirely according to the modern interpretation and explains the particularities and the results of the quantum field theory. Also this work may help to clarify the controversial relation between Maxwell and Dirac equations while presenting an original way to derive the Dirac equation from the chiral electrodynamics, leading, perhaps, to novel conception in interactions between matter and electromagnetic fields. This approach may give a reinterpretation of Majorana equation, neutrino mass, violation of Heinsenberg’s measurement-disturbation relationship and mass generation in systems like graphene devices.

The aim of this work was evaluate the effects of terpinolene on acute inflammatory responses in *** vivo preclinical research using different inflammatory agents to induce acute responses and evaluate the effects of terpinolene in orally treated *** acute inflammatory responses were induced by injecting phlogistic agents in the mice paw to observe the development of pain responses(formalin test)or edema(carrageenan,dextran,histamine,arachidonic acid,and prostaglandin).The antiedematogenic activity was also evaluated using a croton oil-induced ear edema ***,cotton pellet-induced granuloma was used to carry out a pre-liminary evaluation of terpinolene in a chronic inflammatory *** administered terpinolene(5,10,and 20 mg/mL)significantly inhibited ear edema development(by 33.82%,29.63%,and 33,30%,respectively).Following an oral administration,only the highest dose of the monoterpene(200 mg/kg)reduced the licking time of the formalin test in both phases 1(73.55%)and 2(96.61%).The carrageenan-induced edema signifi-cantly inhibited over time following the oral administration of terpinolene at 50 mg/kg(T1:47.74%,T2:54.67%,T3:48.63%,and T4:62.99%),100 mg/kg(T1:72.86%,T2:71.03%,T3:48.63%,and T4:57.83%),and 200 mg/kg(T1:43.22%,T2:34.11%,T3:36.47%,and T4:45.20%).On the other hand,only the dose of 200 (mg/kg)caused a significant reduction of the dextran-induced paw edema(T1:51.18%,T2:60%,T3:50.92%,and T4:65.15%).Regarding the participation of inflammatory pathways,the monoterpene(200 mg/kg,p.o.)had little impact on histamine-induced edema,while the edema induced by arachidonic acid was significantly reduced at all time-points(T1:37.04%,T2:24.32%,and T3:35.13%,and T4:35.53%),which was corroborated by the observation that the compound inhibited the response triggered by prostaglandin E2(PGE2),suggesting inter-ference with downstream signaling ***,terpinolene(200 mg/kg,p.o.)reduced both the weight(21.43%)and total protein content(36.21%)

Chiral Current in a Graphene Battery

引用

Journal of Electromagnetic Analysis and Applications 2012年第10期4卷 426-431页

作者： Hector torres-silva Diego torres Cabezas Escuela de Ingeniería Eléctrica Electrónica Universidad de Tarapacá Arica Chile Modernización y Gobierno Electrónico Ministerio Secretaría General de la Presidencia Santiago Chile.

We review the formulation of graphene’s massless Dirac equation, under the chiral electromagnetism approach, hopefully demystifying the material’s unusual chiral, relativistic, effective theory. In Dirac’s theory, many authors replace the speed of light by the Fermi velocity, in this paper we deduce that in graphene the Fermi velocity is obtained from the connection between the electromagnetic chirality and the fine structure constant when the electric wave E is quasi parallel to the magnetic wave H. With this approach we can consider the properties of electric circuits involving graphene or Weyl semimetals. The existence of the induced chiral magnetic current in a graphene subjected to magnetic field causes an interesting and unusual behavior of such circuits. We discuss an explicit example of a circuit involving the current generation in a “chiral battery”. The special properties of this circuit may be utilized for creating “chiral electronic” devices.
