Microfluidic chips, made of PDMS, are one-side open when fabricated. Another layer of glass, PDMS, or etc is needed. Liquid seal is provided by complete covalent bonding between layers or by external forces like threads, magnets or similar factors. This protocol describes the covalent bonding of PDMS on glass by air plasma technique.

AbstractThe dual laser-produced plasma technique for the study of ionic absorption spectra has been developed by the use of two Q-switched ruby lasers to enable independent generation of the absorbing and back-lighting plasmas. Optical pulse handling is used in the coupling cicuits to enable reproducible pulse delays from 250 nsec. to 10 msec, to be achieved. At delay times > 700 nsec. spectra of essentially pure neutral species are observed. The technique is valuable, not only for obtaining the neutral spectra of highly refractory and/or corrosive materials but also for studying behaviour of ionic species as a function of time. Typical spectra are shown in Fig. 1.

The high temperature corrosion behavior of thermal barrier coating (TBC) systemconsisting of IN-738 LC superalloy substrate, air plasma sprayed Ni24.5Cr6Al0.4Y (wt%)bond coat and air plasma sprayed ZrO2-20 wt% ceria-3.6 wt% yttria (CYSZ) ceramic coatwere characterized. The upper surfaces of CYSZ covered with 30 mg/cm2 , mixed 45 wt%Na2SO4-55 wt% V2O5 salt were exposed at different temperatures from 800 to 1000 oC andinteraction times from 1 up to 8 h. The upper surface plan view of the coatings wereidentified for topography, roughness, chemical composition, phases and reaction productsusing scanning electron microscopy, energy dispersive spectroscopy, talysurf, and X-raydiffraction. XRD analyses of the plasma sprayed coatings after hot corrosion confirmed thephase transformation of nontransformable tetragonal (t') into monoclinic phase, presence ofYVO4 and CeVO4 products. Analysis of the hot corrosion CYSZ coating confirmed theformation of high volume fraction of YVO4, with low volume fractions of CeOV4 and CeO2.The formation of these compounds were combined with formation of monoclinic phase (m)from transformation of nontransformable tetragonal phase (t').

Nas últimas décadas se observa o retorno da religião sob forma de fundamentalismo religioso, utilizando a mídia e instrumentos de pressão política para fazer valer suas crenças, pois diante do receio ao questionamento, os fundamentalistas veem no “outro”, no diferente, uma ameaça a ser combatida e, em alguns casos, extirpada para preservar suas convicções. O presente estudo tem por objetivo discutir as tendências sócio-políticas do fundamentalismo religioso cristão. Para tanto, com método bibliográfico narrativo, visitamos alguns autores em nível nacional e internacional, que abordam as condições que fizeram emergir o fenômeno social do fundamentalismo religioso, sua estruturação e atuação, até suas demandas sócio-políticas. Os resultados apontam que quando se identifica e transfere qualquer responsabilidade pessoal e histórica para as forças externas, o “outro”, entendido como pessoa e/ou instituição, não podemos negar que esse processo alcança dimensões de problema social. Notamos algumas tendências como mudança de movimento religioso para ideologia acirrada, da postura de fiel para militância, do “ad intra” das religiões para demandas “ad extra”, dos altares e púlpitos para ocupações políticas.Palavras-chave: Fundamentalismo Religioso; Protestante; Católico. CHRISTIAN RELIGIOUS FUNDAMENTALISM: SOCIAL-POLITICS TENDENCIESAbstractIn the last decades the return of religion in religious fundamentalism form can be observed, using media and instruments of political pressure, because when facing the fear of questioning, fundamentalists see in the “other”, in the different, a threat to be stopped and, in some cases, extirpated top preserve their convictions.  This study aims to discuss the social-politics tendencies of the Christian religious fundamentalism. For that, with the narrative bibliographic method, we visited some authors of national and international level, that approach the conditions that caused the emergence of the religious fundamentalism social phenomenon, its structure and role, until its social-politics demand. The results show that when any personal or historical responsibility is identified and transferred to external forces, the “other”, understood as person and/or institution, we cannot deny this process reaches dimensions of social problem. We notice some tendencies such as the change of the religious movement to fierce ideology, from the posture of faithful to militancy, from “ad intra” of religions to “ad extra” demands, from the altars and pulpits to political positions.Keywords: Religious Fundamentalism; Protestant; Catholic.
