1. DISRUPTION OF Nannochloropsis gaditana (EUSTIGMATOPHYCEAE) RIGID CELL WALL BY NON-THERMAL PLASMA PRIOR TO LIPID EXTRACTION AND ITS EFFECT ON FATTY ACID COMPOSITION
Abstract This study assessed the effect of non-thermal plasma (NTP) on Nannochloropsis gaditana cell rupture and subsequent lipid extraction. Micrograph images showed that the surface of original N. gaditana cells appeared smooth and had no apparent holes, whereas after NTP the cells showed a non-uniform apparently fractured surface with many pores and large

2. (DIS)ABLING BODY AND CONSCIOUSNESS: TECHNOLOGICAL AFTERNESS AND AFTER-HUMANS IN REALIVE AND UPGRADE
RESUMO Este artigo fala sobre espaços pós-humanos e pós-vida tecnológica associados à fisionomia dos humanos. A alteração mecânica no funcionamento biológico é experimentada diretamente na apreensão da consciência orgânica. A ruptura na consciência divide-a em duas partes distintas - uma pertencente ao humano em desaparecimento, a outra ao cibe

3. Experimental mapping of the thermodynamic losses in vapor compression refrigeration systems
The present study introduces a methodology for mapping the thermodynamic losses of vapor compression refrigeration systems which consists of a theoretical model that splits the coefficient of performance into four terms: (i) the coefficient of performance of an ideal cycle (Carnot), (ii) the efficiency of a real cycle running with an ideal compressor, (iii)

4. Geração automática de código para a execução em um ambiente de computação em DataFlow
The computers architectures are becoming more distributed and hierarchical,that is, there exist lots of computers in a cluster and there are many processors in these computers and these processors have multiple cores. Many models have been proposed to explore the features of the computers architectures. The Data-flow computing models stand out among the prop

6. Comparative study of skin pre and post fractional photothermolysis with Erbium-YAG 2940nm for the treatment of perioral wrinkles: a clinical, histological and immunohistochemical analysis / Estudo comparativo da pele pré e pós-laser fracionado minimamente ablativo com Erbium-YAG de 2940nm para tratamento de rítides da região perioral: avaliação clínica, anátomo-patológica e imuno-histoquímica
There are several treatment options for skin photoaging. One of them widely used nowadays is lasertherapy. The development of lasers technology introduced a new therapeutic concept for aging skin: ablative fractional photothermolysis. This technology combines the visible effects of an ablative therapy with the comfort and safety of nonablative methods. Befor

7. Andreev transport in double quantum dots coupled to superconductor and ferromagnetic leads / Transporte por reflexão de Andreev em pontos quanticos duplos acoplados a eletrodos supercondutores e ferromagneticos
In this work we studied the quantum transport in two hybrid nanostructures composed of double quantum dots (DQD)s coupled to superconductor (S) and ferromagnetic (F) leads. The first nanostructure, denoted by F - QDa - QDb - S, is composed of a ferromagnet, two quantum dots, and a superconductor connected in series. In the second nanostructure, denoted by (

8. Estudo estrutural de nanossistemas semicondudores e semicondutores implantados por difração de raios-X de n-feixes / Structural study of semiconductors nanosystems and implanted semiconductors by means of n-beams X-ray diffraction
In this paper, X-ray multiple diffraction (MD) associated with the advantages of synchrotron radiation appears as a high-resolution microprobe and it is used to obtain relevant contributions to the study of structural properties of semiconductor materials, as they present themselves nanosystems epitaxial or implanted with ions. The study and detection of neg

9. Infrared and chemical characterization of natural amethysts and prasiolites colored by irradiation
The infrared bands of amethyst and prasiolite samples from different origins were correlated to the trace elements contents. Amethysts have an iron content greater than 20 ppm and a low content of sodium and potassium. Prasiolites have an aluminum content greater than 120 ppm and a higher overall trace elements content, which accounts for a strong absorption

10. Use of Component Mode Synthesis and Axial Splits in Ducts for Noise Control of Higher Order Duct Mode / Utilização de síntese modal de componentes e particionamento axial de dutos para controle dos modos acústicos de alta ordem
In this study, the proposal of this work is centered in the noise reduction in ducts that became, over the years, a field of intense application. The traditional approach to acoustic noise control in ducts uses passive techniques and fixed reactive silencers to mitigate the noise. In this moment, the Active Control of Noise (ANC) is an attractive approach to

11. Respiros: por um estado de jogo entre o teatro e a clínica
This work is the effort to promote a conversation beetwen theatre and clinic, where the and, the intersection, is considered the main point. With this aim, the concept of encounter is taken as a mediator for the exercise of writing and thinking. To find a way in beetwen these two fields, a territory of research is created which is denominated as teatrar (to

12. Diversidade genética do vírus da hepatite B no Brasil: genótipos, subgenótipos e recombinantes. / Genetic diversity of the hepatitis B virus from Brazil: genotypes, subgenotypes and recombinants.
O vírus da hepatite B (HBV), membro da família Hepadnaviridae, possui genoma de DNA circular com cerca de 3200 pb e quatro regiões abertas de leitura. Apesar do pequeno tamanho do genoma viral, uma grande diversidade genética é observada. O HBV é classificado em oito genótipos, designados de A a H, e pelo menos 24 subgenótipos com distintas distribui
