Courageous women in media: Marcos and censorship in the Philippines
No full textWhen Philippine President Ferdinand Marcos declared Martial Law in 1972, press freedom became the first casualty in the country that once boasted of being the 'freest in Asia'. Printing presses, newspaper offices, television and radio stations were raided and padlocked. Marcos was especially fearful of the press and ordered the arrest of journalists whom he charged with conspiring with the 'Left'. Pressured into lifting martial law after nearly 10 years, Marcos continued to censor the media, often demanding publishers to sack journalists whose writing he disapproved of. Ironically, he used the same 'subversive writings' as proof to Western observers that freedom of the press was alive and well under his dictatorship. This article looks at the writings of three female journalists from the Bulletin Today. The author examines the work of Arlene Babst, Ninez Cacho-Olivares, and Melinda de Jesus and how they traversed the dictator's fickle, sometimes volatile, reception of their writing. Interviewed is Ninez Cacho-Olivare, who used humour and fairy tales in her popular column to criticise Marcos, his wife, Imelda, and even the military that would occasionally 'invite' her for questioning. She explains an unwritten code of conduct between Marcos and female journalists that served to shield them from total political repression
Producing Ferdinand E. Marcos, the Scholarly Author
No full textThisarticle discusses the compelling evidence—found in various primaryand secondary sources and analyzed through methods drawn from bookhistory and plagiarism detection—that not one of the books authored byPres. Ferdinand E. Marcos was actually written by him. Thearticle alsoshows how many of “Marcos’s” books had either plagiarized content(e.g., republishing contents from previous works) or were “padded” withlengthy appendices. It also explains the seemingly far-reaching distributionnetwork of these books. Lastly, thearticle looks into how these books,although they have not been republished for decades, continue to servetheir intended functions.KEYWORDS: FERDINAND E.

CFD based aerodynamic redesign of a Marcos LM600
No full textThe final years of the 1960s mark the introduction of aerodynamics to the field of motorsport and they have grown to be inextricably connected ever since. The competing cars in nearly every motorsport category are fitted with aerodynamic devices while Formula One teams actually have departments that are primarily concerned with the aerodynamic design of their vehicles. The GT-class is another motorsport category that hosts cars that are predominantly shaped with the aim to optimize aerodynamic efficiency. The Marcos LM600 is one of the cars that competes in the GT-class and forms the sculpture of this thesis. The subject of this thesis is to enhance the aerodynamic characteristics of the Marcos LM600 through utilization of Computational Fluid Dynamics (CFD). This implies that on going through this report a number of modifications to the Marcos LM600 will be presented with the aim of obtaining an aerodynamically improved racing car. In a sense the Marcos LM600 thus resembles a sculpture that assumes its final shape after a succession of modifications. The aerodynamic characteristics that are of primary significance to a racing car are the downforce and drag. The obvious target is to maximize the downforce and downforce-to-drag ratio. Apart from this force ratio, the downforce distribution between the wheel axes is another important racing car characteristic. The actual handling stability of the car is determined by the force balance between the front and rear wheels. Too much ”grip” on the front wheels causes oversteer, while too much rear wheel grip causes understeer. Thus when designing racing cars, the aerodynamicist should take into account the front wheel and rear wheel downforce and to obtain either a vehicle with neutral steer or slightly oversteer1. However, vehicle handling is beyond the scope of this thesis, which is why the Marcos LM600 will only be optimized in terms of downforce and drag, leaving out their effect on the vehicle stability.Aerospace Engineerin
Reparo ósseo após enxerto ósseo autógeno e implante de hidroxiapatita absorvível granulada sob influência de campo magnético estático : estudo experimental em calvária de ratos
No full textProposição: avaliar histológica e bioquimicamente o efeito de enxerto ósseo autógeno e implante de hidroxiapatita (HA) sintética (HAP 91®), sob influência de campo magnético estático, no reparo ósseo na calvária de ratos. Materiais e métodos: utilizaram-se defeitos críticos de 5 mm realizados na calvária de 60 ratos Wistar. Os animais foram submetidos a quatro diferentes intervenções: enxerto ósseo autógeno ou implante de HA, com e sem a presença de campo magnético estático, sepultado, com intensidade entre 40 e 70 G. Foi realizada análise histológica histométrica e descritiva dos defeitos ósseos em 15, 30 e 60 dias pós-operatórios. Realizou-se análise da atividade sistêmica da enzima fosfatase alcalina nos mesmos tempos operatórios. Para controle bioquímico utilizaram-se cinco animais (Naive). Resultados: o reparo ósseo foi mais acelerado no grupo de enxerto autógeno sob influência de campo magnetico do que no mesmo grupo sem influência magnética. O enxerto ósseo autógeno demonstrou reparo ósseo superior ao implante de HA. A atividade da enzima fosfatase alcalina teve sua maior expressividade em 30 dias pós-operatórios. Neste mesmo tempo operatório, os grupos com aplicação de campo magnético apresentaram atividade enzimática inferior aos grupos sem tal influência. Conclusões: o implante de HA demonstrou ser inferior ao enxerto ósseo autógeno no reparo ósseo. O campo magnético estático não causou influência sobre o reparo ósseo. A enzima fosfatase alcalina teve sua atividade diminuída em 30 dias pós-operatórios pela influência do campo magnético estático.Purpose: to evaluate histologically and biochemically the effect of autogenous bone graft and synthetic hidroxiapatite (HA) implant (HAP 91®), under static magnetic field influence, on bone healing in rat calvaria. Materials e methods: 5-mm critical-size defects were created in each calvarium of 60 Wistar rats. They were submitted into four different interventions: autogenous bone graft or HA implant, with or without static magnetic field influence with intensity ranging from 40 to 70 G. Histometric and descriptive analysis of the bone defects were performed in 15, 30 and 60 days after surgery. At the same times, the systemic activity of alkalin phosphatase was measured. Five animals (Naive) were used as biochemical control. Results: bone healing was faster in the autogenous bone graft group under magnetic field stimulation than in the same group without the magnetic influence. The autogenous bone graft showed better results for bone healing than the HA implant. Alkalin phosphatase activity had its higher expression in 30 days after surgery. At this time the groups under magnetic stimulation had lower alkalin phosphatase activity than the groups without magnetic field influence. Conclusions: the HA implant showed worse bone healing than the autogenous bone graft. The static magnetic field did not cause any influence on bone healing. alkalin phosphatase had its activity lowered in 30 days after surgery in the groups under magnetic field influence
Control tardío de rama negra de 30 cm de altura en un barbecho previo al cultivo de soja
No full textRama negra (Conyza sp.) es una especie anual que se comporta como maleza problema en barbechos químicos y en cultivos estivales y se encuentra ampliamente distribuida en casi todo el territorio argentino (Aapresid, 2019). Emerge entre mayo y octubre, con un pico en otoño y otro en primavera (Gianelli, Bedmar et al., 2017). Cuando emerge en otoño permanece en estado de roseta en invierno hasta principios de primavera. Recién con el incremento de las temperaturas en agosto elonga su tallo. En cambio, en primavera la elongación se produce a los pocos días de haber emergido (Metzler et al., 2013). La eficacia de los herbicidas se reduce significativamente cuando comienza la elongación del tallo (Travlos y Chachalis, 2013; Santos et al., 2014) por lo que se recomienda su manejo durante el invierno, en estado de roseta. (Oliveira Neto et al., 2010; Sansom, Saborido y Dubois, 2013). En Argentina se han documentado biotipos de Conyza sp. con resistencia simple a glifosato (Puricelli, 2012), a inhibidores de ALS (Balassone et al., 2019) y actualmente hay sospechas de resistencia múltiple a 2,4-D, dicamba y a inhibidores de PPO como saflufenacil (Aapresid, 2020).EEA Marcos JuárezFil: Belluccini, P.

Synthesis of steroidal quinones and hydroquinones from bile acids by Barton radical decarboxylation and benzoquinone addition: Studies on their cytotoxic and antifungal activities
No full textTwelve new hydroquinones and quinones (4a-c to 7a-c) derived from free or peracetylated bile acids were prepared by a Barton decarboxylation reaction, with subsequent trapping of the resulting free radical by benzoquinone. All new compounds were completely characterized by 2D NMR techniques and screened for antifungal and cytotoxic activity. One of the new hydroquinones (7b) showed promising results against the human pancreatic ductal carcinoma cell line PANC1, with similar cytotoxic activity as the commercial chemotherapy drug doxorubicin.Fil: Siless, Gastón Ezequiel.

Parrhesía e loucura no exemplo de Estamira
No full textTese (doutorado) - Universidade Federal de Santa Catarina, Centro de Filosofia e Ciências Humanas, Programa de Pós-Graduação em Filosofia, Florianópolis, 2015.Um autor como Michel Foucault (1926-1984), ao apresentar um estudo extenso sobre saber, poder e ética, deixa o leitor com dúvidas e indagações: O sujeitado ao poder não teria como se contrapor à submissão? O poder psiquiátrico, com seus saberes sobre a loucura, seria tão poderoso assim? Na tentativa de responder estas questões, estabeleceu-se como objetivo geral investigar a parrhesía e a loucura no exemplo de Estamira. Como pressuposto metodológico, optou-se pelos escritos de Michel Foucault sobre a temática da loucura. Na análise do documentário a respeito de Estamira, produzido por Marcos Prado em 2004, foram analisadas algumas cenas, fundamentando-se, sobretudo, em seus últimos escritos, de 1980 a 1984, do Collège de France. O pensamento último de Foucault evidencia uma preocupação histórica do que seria o cuidado de si e a parrhesía no período da Grécia Clássica, por volta do séc. IV a.C., o período helênico romano séc. I e II d.C. e os primeiros cristãos (IV a V d.C.). O autor consegue perceber, na antiguidade grega, a existência de uma subjetividade que não segue normas, a qual se torna uma prática de liberdade (práticas ascéticas), uma busca de como dizer a verdade (parrhesía) que leva a uma constituição ética atrelada à estética da existência da vida do sujeito. Conclui-se, com base nas análises históricas foucaultianas, que o exemplo de Estamira nos remete a uma ?ontologia do presente?, ?ontologia dos discursos verdadeiros?, uma concepção de subjetividade, de verdade e de filosofia de vida para o indivíduo, com sua loucura, transformar sua vida e ser diferente do que é, governando a si mesmo pela parrhesía, ser franco, falar a verdade.Abstract : An author such as Michel Foucault (1926-1984) when presenting an extensive study of knowledge, power and ethics, leaves the reader with doubts and questions: The subjected to power could not possibly oppose itself from submission? The psychiatric power, with its knowledge about insanity, would be that powerful? In the attempt to answer these questions, it was established as a general objective to investigate the parrhesia and insanity in the case of Estamira. For the methodological presupposition, it was chosen the writings of Michel Foucault on the theme of madness. In the documentary film analysis about Estamira, produced by Marcos Prado in 2004, some scenes were analyzed mostly based in his later writings, from 1980 to 1984, from the Collège de France. The final thought of Foucault reveals a historical concern of what would be the self care and the Parrhesia in the Classical Greece period from around the IV century B.C., the Roman Hellenistic period during the I and II century A.D. and the early Christians (IV to V A.D.). The author is able to perceive that in Greek antiquity, the existence of a subjectivity that does not follow rules, which turns to a practice of freedom (ascetic practices), a search for how to tell the truth (parrhesia) leading to an ethical constitution tied to the aesthetics of existence of the subject´s life. The conclusion is, based on Foucault's historical analysis, that the example of Estamiranos refers to an "ontology of the present", "ontology of real discourses," a conception of subjectivity, truth and life philosophy for the individual, with his insanity, to transform his life and be different than it is, ruling himself through parrhesia, be honest and to tell the truth
