Estrategias felinas: discurso poetico X midia na poesia brasileira contemporanea : Armando Freitas Filho e Sebastião Uchoa Leite
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Comunicação e ExpressãoA presente dissertação analisa na produção textual de Armando Freitas Filho e Sebastião Uchoa Leite o conflito entre a mídia, como veiculadora de discursos homogeneizantes na sociedade, e o discurso poético como voz alternativa, marcada pela singularidade e pelo exercício crítico em relação às noções de sujeito, subjetividade, verdade, discurso. Para isso, foram estudadas principalmente obras escritas nos anos 1980
Treadmilling by FtsZ filaments drives peptidoglycan synthesis and bacterial cell division
No full textCoordinating cell wall synthesis and cell division
Most bacteria are protected by peptidoglycan cell walls, which must be remodeled to split the cell. Cell division requires the tubulin homolog FtsZ, a highly conserved cytoskeletal polymer that specifies the future site of division. Bisson-Filho
et al.
and Yang
et al.
found that the dynamic treadmilling of FtsZ filaments controls both the location and activity of the associated cell wall synthetic enzymes. This creates discrete sites of cell wall synthesis that circle around the division plane to divide the cell.

Adelmo Genro Filho e a teoria do jornalismo no Brasil: uma análise crítica
No full textTese (doutorado) - Universidade Federal de Santa Catarina, Centro de Filosofia e Ciências Humanas, Programa de Pós-Graduação em Sociologia Política, Florianópolis, 2015.A afirmação de Adelmo Genro Filho, em "O Segredo da Pirâmide: para uma teoria marxista do jornalismo", de que o jornalismo é uma forma de conhecimento cristalizada no singular mobilizou jornalistas, pesquisadores e professores nos últimos 27 anos para instituição e legitimidade das teorias do jornalismo no Brasil. Com o arcabouço teórico e filosófico da Ontologia Crítica de Marx e Lukács, este estudo expõe as mediações presentes na produção e recepção da teoria, bem como os conceitos filosóficos que fundamentam a assertiva de Genro Filho. O trabalho divide-se em duas partes interdependentes. Na primeira, são trabalhadas as principais questões que se impunham para o jornalismo brasileiro nos anos 1980 (com ênfase para a formação acadêmica, a escrita jornalística e a hierarquia dos profissionais), a biografia do autor e o modo como o livro foi recepcionado pelos professores e pesquisadores em jornalismo no Brasil. A segunda parte reconstitui as bases filosóficas do livro, recuperando o entendimento ontológico do autor e o modo como esses fundamentos otimizam sua compreensão do jornalismo como forma de conhecimento. O objetivo é o de demonstrar como as escolhas teóricas do autor possuem estreita ligação com sua biografia e o modo como ele compreendia as questões de sua época. Ao passo que, por meio de análise do modo de recepção do livro, foi possível estabelecer uma cartografia da produção brasileira com base em 411 textos que citam "O Segredo da Pirâmide", evidenciando que o processo de institucionalização para a defesa do jornalismo como profissão, graduação especializada e com teorias específicas coincide com esse mapa. Paradoxalmente, demonstra-se que o processo de recepção do livro se faz acompanhar de uma negação da peculiar base marxista que o fundamenta, o que motiva o estudo detalhado das categorias utilizadas por Genro Filho.Abstract : In the book ?O Segredo da Pirâmide: para uma teoria marxista do jornalismo" [?The Secret of the Pyramid: for a Marxist theory of journalism"], Adelmo Genro Filho stated that journalism is a form of knowledge that is crystallized in the singular. This statement has mobilized journalists, researchers and professors over the last 27 years for the institution and legitimacy of theories of journalism in Brazil. With the theoretical and philosophical framework of Critical Ontology of Marx and Lukács, this study exposes the mediations present in the production and reception of the theory and the philosophical concepts that ground the Genro Filho's statement. The work is divided into two interdependent parts. At first, the text brings the main issues that were necessary to the Brazilian journalism in the 1980s (with emphasis on the academic, journalistic writing and the hierarchy of professionals), the author's biography and how the book was received by professors and researchers on journalism in Brazil. The second part reconstitutes the philosophical bases of the book, recovering the ontological understanding of the author towards journalism and how those fundamentals optimize the understanding of journalism as a form of knowledge proposed by the author. The objective was to demonstrate how the author's theoretical choices have close connection with his biography and how he understood the issues of his time. Simultaneously, through the analysis about the book's reception, it was possible to establish a cartography of the Brazilian production based on 411 texts mentioning "The Secret of the Pyramid", evidencing that the process of institutionalization for the defense of journalism as a profession, specialized graduation and with specific theories coincides with that map. Paradoxically, it is demonstrated that the book's reception process is accompanied by a denial of peculiar Marxist basis underlying it, which motivates the detailed study of the categories used by Genro Filho

No full textRozprawa doktorska mgr Faustino Alexandre pod tytułem „Aspekty międzynarodowe wojny domowej w Angoli”jest rezultatem badań prowadzonych w Angoli, z wykorzystaniem literatury naukowej polskiej i anglojęzycznej. Autor weryfikuję tezę: wojna domowa w Angoli była konsekwencją Zimnej Wojny prowadzonej przez USA i ZSRR z udziałem ich satelitów, wykorzystujących konflikt plemienny w kraju afrykańskim, jako zastępczej płaszczyzny rywalizacji dwóch przeciwstawnych sobie bloków polityczno-ideologicznych. Na wstępie autor przedstawia w ujęciu naukowym problematykę wojny domowej w świetle prawa międzynarodowego. W pozostałych czterech rozdziałach, kolejno omawia aspekty przebiegu wydarzeń Angoli w latach 1975-2002. Szczególnie wyakcentowane są geneza i ewolucja wojny domowej w Angoli oraz jej umiędzynarodowienie; meandry procesu pokojowego i poszczególnych faz wojny; ingerencję państw obcych; role międzynarodowych organizacji w przywracaniu pokoju w Angoli; oraz patriotyczny refleks walczących ze sobą angolańskich, narodowych elit militarnych i politycznych, które bez udziału obcych znalazły metodę na pokojowe współistnienie, i od kilkunastu lat w Angoli panuję pokój. Rozprawa zawiera bibliografię liczącą 270 pozycji oraz aneksy zawierające: chronologie wojny i pokoju w Angoli, dokumenty porozumień w Bicesse, Estorylu i Lusace oraz bogate w treści faktograficzne, zobrazowania graficzne wojny domowej w Angoli.

No full textBolbonema braziliensis sp. n. (measurements in Table 1, Figures 2, 3 and 4). Type material: Holotype Male adult MNRJ 390. Station CME1 (05°01'55.3''S, 36°12'20.4''W). Paratype female: Adult, MNRJ 391. Station CME1 (05°01'21.2''S, 36°12'18.7''W). Other paratypes: 5 females (221 and 225 LMZOO-UFPE), 6 males (226–230 LMZOO-UFPE) and 2 J1, 1 J2 and 3 J3 (231 LMZOO-UFPE), data as for holotYpe. Etymology. The specific epithet “ braziliensis ” is given for the location where the material was found, in BraZil. Description. HolotYpe (Figures 2 and 3). BodY cYlindrical, Yellowish brown, tapering slightlY toward each end. Cuticle annulated eXcept in final portion of tail, no lateral differentiation. Eight longitudinal rows of somatic setae; two subdorsal, two subventral and four sublateral. TheY start from cervical region to level of cloaca, alternating in long setae with shorter setae. Head capsule well developed with thick cuticle without annulations. Anterior sensilla arrangement: siX outer labial papillae (difficult to see) and four cephalic setae positioned at middle level of fovea amphidialis. Fovea amphidialis crYptospiral, relativelY large, posterior border in contact with cuticle striations, occupYing 64% of diameter of head. Buccal cavitY small, with one dorsal tooth and one small ventral tooth, not alwaYs visible. PharYnX muscular with well-developed posterior bulb. Cardia and eXcretorYsecretorY sYstem not observed. Nerve ring located 54 µm from anterior region. Reproductive sYstem monorchic, with single anterior testis situated to left of intestine, outstretched. Sperm cells globular. Spicules arched, proXimal region eXpanded. Gubernaculum a bent rod dorsallY oriented. Velum absent. Two precloacal setae inserted on two small papillae (Fig 2E) in subventral position. Tail conical, with three small caudal glands and spinneret. ParatYpe female (Figures 3 and 4). Similar to the male in bodY siZe, with minor differences: in female, cephalic setae positioned at posterior level of fovea (Fig 4B). Female didelphic, ovaries antidromouslY refleXed and both genital branches to right of intestine. Vulva as simple transverse slit-like aperture. ProXimal portion of vagina slightlY cuticularised (Fig 3C). Globular sperm cells visible. No egg found. Vulva located at 49% of total bodY length (689 µm distant from anterior end). Tail conical. Juveniles (Figure 2). Similar to adults, eXcept not possessing some characteristics such as supplements; reproductive sYstem immature. Juveniles in stage 1, without rows of somatic setae. Five juveniles were found, two in stage 1, one in stage 2 and two in stage 3. Diagnosis. Bolbonema braziliensis sp. n. is characteriZed bY the crYptospiral fovea amphidialis, arched spicules, gubernaculum a bent rod dorsallY oriented, and two subventral precloacal setae just above the cloaca. Differential diagnosis. Bolbonema braziliensis sp. n. is similar to Bolbonema longisetosum (Jensen, 1985) in the shape and siZe of the fovea amphidialis, cephalic setae at the middle level of the fovea amphidialis, spicules arched and the proXimal region eXpanded, and papilliform supplements associated with setae. It differs from B. longisetosum in the number of papillae supplements (two in B. braziliensis sp. n. and 24 in B. longisetosum) and the absence of an apophYsis. Bolbonema braziliensis sp. n. is comparable to Bolbonema brevicolle Cobb, 1920 in the shape of the fovea amphidialis. It differs in the absence of subcephalic setae (present in B. brevicolle) and the shape of the spicules (eXpanded in B. brevicolle). Bolbonema braziliensis sp. n. can be distinguished from Bolbonema spiralis Hourston & Warwick, 2010 bY the shape of the fovea amphidialis (spiral in B. spiralis), the presence of precloacal supplements, and the shape of the spicules and gubernaculum (arched without a rounded capitulum; and a small simple gubernaculum in B. spiralis).Published as part of Larrazábal-Filho, Alexandre L., Neres, Patrícia F. & Esteves, André M., 2018, The genus Bolbonema Cobb, 1920 (Nematoda: Desmodoridae): emended diagnosis, key to males, and description of three new species from the continental shelf off northeastern Brazil, pp. 551-570 in Zootaxa 4420 (4) on pages 553-557, DOI: 10.11646/zootaxa.4420.4.6, http://zenodo.org/record/145544
