Sobre las formas de vida tecnológicas y las prácticas biopolíticas
Flavia Costa
Revista Observaciones Filosóficas , 2011,
Abstract: In Critique of Information (2005), sociologist Scott Lash said that our time trend coincides with the deployment of "technological life forms." Talking about "lifestyles" suggests Lash, is to be in the area of intersection between natural-biological realities and social-cultural. And referring to "technological life forms" include in that scenario involves a third term, the technique, which enters into a composition scheme with the other two and indicates a movement of action "remote" beyond the limits of the anthropomorphic own body. In that book Lash staged the term, but it developed more than a few paragraphs. Here I seek to deepen that notion outlined succinctly by Lash, which I consider particularly fruitful for several reasons. Mainly because it serves to highlight the intimate connection between two processes that have usually been analyzed separately: first, the gradual politicization of biological life (or biological concept of the political, that is, the thesis biopolitics developed from some the writings, courses and lectures taught by Michel Foucault in the early 1970) and secondly, the increasing mechanization of production processes, human capabilities and even lifestyles. Briefly, the process of modernization in its restricted appearance in our time appears to be linked with the extension of the life and the human body of principles of autonomy of processes, improvement, optimization and individual responsibility for the care of psycho-physical endowment ("human capital "own or acquired) characteristic of a particular combination of industrial-capitalist technical code and emergent forms of neoliberal governmentality.
Disease progression after R-CHOP treatment associated with the loss of CD20 antigen expression
Bellesso, Marcelo;Xavier, Flavia Dias;Costa, Renata Oliveira;Pereira, Juliana;Siqueira, Sheila Aparecida Coelho;Chamone, Dalton Alencar Fischer;
Revista Brasileira de Hematologia e Hemoterapia , 2011, DOI: 10.5581/1516-8484.20110036
Abstract: a case of a follicular lymphoma transformed into a cd20+ is described which progressed with the loss of cd20 expression after 8 cycles of r-chop. this phenomenon is not a rare event and has shown poor prognosis. our purposes are to describe this event and suggest biopsy in relapsed or progressive disease.
Prospects for Higgs properties measurements at future colliders
Flavia de Almeida Dias
Physics , 2015,
Abstract: The LHC Run-1 was very successful and included the discovery of a new particle with mass of about 125 GeV compatible with the Higgs boson predicted by the Standard Model. The prospects for Higgs physics at the high-luminosity LHC and at future colliders are presented. In particular, the ultimate precision attainable for the couplings measurements of the 125 GeV particle with elementary fermions and bosons is discussed along with prospects for self-coupling measurements, for the ATLAS and CMS detectors at the upgraded LHC.
Morphology and Thermal Properties of Core-Shell PVA/PLA Ultrafine Fibers Produced by Coaxial Electrospinning  [PDF]
Raquel P. Gon?alves, Flavia F. F. da Silva, Paulo H. S. Picciani, Marcos L. Dias
Materials Sciences and Applications (MSA) , 2015, DOI: 10.4236/msa.2015.62022
Abstract: Coaxial electrospinning process was used to produce biodegradable membranes made of coreshell fibers of a poly(lactic acid) (PLA) shell and a poly(vinyl alcohol) (PVA) core. Scanning electron microscopy analyses of these structures showed that the PLA shell can present certain porosity depending on the process condition. FTIR-ATR and contact angle measurements also suggested imprisonment of the PVA core within the PLA shell. This type of structure was also confirmed by means of transmissions electron microscopy. The morphology of these fibers was dependent on the flow rate of both core and shell solutions, and homogeneous and smooth surface was only attained when the flow rate of the external PLA solution was 4 times the flow rate of the internal PVA solution. The increase in the PLA solution flow rate increases the diameter of the core-shell fiber which reaches up to 1.7 μm. Nevertheless, fibers with smaller average diameter could also be produced (200 nm). These core-shell fibers presented improved hydrophilicity as compared with monolithic PLA fibers.
Sacralidade e crueldade no direito natural segundo Hobbes e Agamben =Sacredness and cruelty in natural right according to Hobbes and Agamben
Costa, Gilcilene Dias da
Veritas , 2011,
Abstract: O presente texto visa discutir o sentido da sacralidade e da crueldade no direito natural e na cena política a partir de Hobbes e Agamben. Relaciona o conceito hobbesiano de estado de natureza às figuras do direito romano arcaico, homo lupus (homem lobo) e homo sacer (homem sagrado) em seu duplo processo de inclus o/exclus o da vida nua (zoé) na vida política (bíos). Adentra nos limites da natureza e da condi o humana, a fim de perceber as flutua es de sentido implicadas na situa o de abandono que acerca um malfeitor ou bando junto à comunidade, com sua exposi o à morte ou desaparecimento social sem as formas sancionadas pela lei. Reitera a permanente fronteira entre animal e humano, limite paradoxal e intransponível, situado entre polidez e nudez, crueldade e sacralidade, bem e mal. The present text seeks to discuss the sense of sacredness and cruelty in natural right and in the political scene of Hobbes and Agamben. It relates Hobbes’ concept of state of nature to the figures in ancient Roman right of homo lupus (wolf man) and homo sacer (sacred man) in its dual process of inclusion/exclusion of naked life (zoé) in the political life (bíos). It goes into the limits of human nature and condition in order to understand the fluctuations of meaning involved in the situation of abandonment that brings a malefactor or band close to the community, with its exposure to death or social disappearance outside the forms sanctioned by the law. It stresses the permanent border between animal and human, a paradoxical and insurmountable limit situated between politeness and nakedness, cruelty and sacredness, good and evil.

Classicality Criteria
Nuno Costa Dias
Mathematics , 1999,
Abstract: We present two possible criteria quantifying the degree of classicality of an arbitrary (finite dimensional) dynamical system. The inputs for these criteria are the classical dynamical structure of the system together with the quantum and the classical data providing the two alternative descriptions of its initial time configuration. It is proved that a general quantum system satisfying the criteria up to some extend displays a time evolution consistent with the classical predictions up to some degree and thus it is argued that the criteria provide a suitable measure of classicality. The features of the formalism are illustrated through two simple examples.
Half Quantization
Nuno Costa Dias
Mathematics , 1999, DOI: 10.1088/0305-4470/34/4/306
Abstract: A general dynamical system composed by two coupled sectors is considered. The initial time configuration of one of these sectors is described by a set of classical data while the other is described by standard quantum data. These dynamical systems will be named half quantum. The aim of this paper is to derive the dynamical evolution of a general half quantum system from its full quantum formulation. The standard approach would be to use quantum mechanics to make predictions for the time evolution of the half quantum initial data. The main problem is how can quantum mechanics be applied to a dynamical system whose initial time configuration is not described by a set of fully quantum data. A solution to this problem is presented and used, as a guideline to obtain a general formulation of coupled classical-quantum dynamics. Finally, a quantization prescription mapping a given classical theory to the correspondent half quantum one is presented.
The Porcine Pulmonary Surfactant Protein A (pSP-A) Immunogenicity Evaluation in the Murine Model  [PDF]
Sandra de Cássia Dias, Fernanda Lucio dos Santos, Dirce Sakauchi, Dmitri Iourtov, Isaias Raw, Flavia Saldanha Kubrusly
Pharmacology & Pharmacy (PP) , 2010, DOI: 10.4236/pp.2010.11004
Abstract: This paper investigated the porcine surfactant protein A (pSP-A) immunogenicity in murine model. Many elegant stu-dies about SP-A therapeutic applications are available however specific studies about its exogenous immunogenicity were not easily assumed. Therefore, we investigated the immunogenicity of this porcine protein in mice. The mice re-ceived pSP-A subcutaneously on days 0 and 7. The animals were observed during 90 days and the blood was collected on days 30, 60 and 90 for assessment the immunogenic potential of pSP-A. Some animals showed circulating antibodies above the screening cut point, which was calculated based on control mice sera signals. However, those antibodies were considered false positive read-outs by the performed competitive inhibition assay. Also no neutralizing antibodies were detected able to avoid the porcine protein ability to promote lipid aggregation. So far in this model, porcine surfactant protein-A could be considered not immunogenic.
