Bibliographie Leo Perutz : Stand: 26. April 2010
No full textIn den gut eineinhalb Jahrzehnten, die seit der Bibliographie von Hans-Harald Müller und Wilhelm Schernus (Nr. 140) vergangen sind, hat sich die Perutz-Forschung etabliert. Dies zeigt schon ein flüchtiger quantitativer Vergleich. Der Abschnitt "Wissenschaftliche Untersuchungen" bestand damals aus einer Handvoll Magisterarbeiten und Dissertationen; in der vorliegenden Bibliographie nimmt die Sekundärliteratur mehr als die Hälfte des Raums ein. Die Rechtfertigung einer neuen Perutz-Bibliographie liegt denn auch vor allem darin, ein aktuelles, möglichst vollständiges Verzeichnis der wissenschaftlichen Literatur zu Leo Perutz (unter Einschluß der vor 1990 erschienenen Titel) vorzulegen. Der Abschnitt "Primärliteratur" schließt dagegen chronologisch an Müller und Schernus an

Possible Cyclisity of the Spotted Activity of AM Leo
No full textIt is known that the light curves of short-period contact binaries of the W UMa type are constantly changing. Currently, the most likely cause of such changes is believed to be the presence of spots on the surface of their components. Based on the ten-year AM Leo photometric CCD monitoring carried out by the author from 2007 to 2017, the presence of a possible cyclicity of the spot activity with a period of 7.5 years was found.Известно, что кривые блеска короткопериодических контактных систем типа W UMa изменяются со временем. В настоящее время наиболее вероятной причиной таких изменений считается наличие пятен на поверхности их компонентов. На основе результатов десятилетнего фотометрического ПЗС мониторинга AM Leo, проведенного автором в 2007 2017 гг., установлено наличие возможной цикличности пятенной активности с периодом 7.5 года.Работа выполнена при финансовой поддержке государства в лице Министерства образования и науки Российской Федерации (базовая часть госзадания, РКAAAA–A17–117030310283–7)
Cyclicity of variations of the magnetic field of the eclipsing variable AM Leo
No full textНа основе обработки данных 14-летнего фотометрического мониторинга контактной затменной переменной звезды AM Leo типа W UMa, проводимого с 2007 по 2020 г. на телескопах Коуровской обсерватории УрФУ, были обнаружены циклические изменения блеска системы с периодом 7.6 ± 0.6 г., не связанные с явлением затмений или приливными деформациями компонентов, а также циклические малоамплитудные изменения орбитального периода системы с таким же значением периода. Сделан вывод, что малоамплитудные изменения блеска и периода системы обусловлены циклическим изменением магнитного поля компонентов контактной системы AM Leo, что проявляется в изменении средней поверхностной температуры общей оболочки системы из-за изменения площади холодных или горячих пятен на поверхности компонентов, а также влияния эффекта Эпплгейта на период системы.Based on the 14-year photometric CCD monitoring of the contact eclipsing variable star AM Leo of type W UMa carried out author from 2007 to 2020 at the telescopes of the Kourovka observatory UrFU, the presence cyclic variations in brightness of the system with a period of 7.6±0.6 years, not associated with the phenomena of eclipses and tidal deformations of the components, as well as low-amplitude cyclic variations of the orbital period with the same value of the oscillation period, were found. It was concluded that the low-amplitule variations of the brightness and period of the system are due to the cyclic changes of the magnetic field of the components of the AM Leo, which manifests itself in a change in the average surface temperature of the overall system shell due to changes in the area of cold or hot spots on the surface of the components, as well as the influence of the Applegate effect on the system period
Theodor W. Adorno: um crítico na era dourada do capitalismo
No full textTese (doutorado) - Universidade Federal de Santa Catarina, Centro de Filosofia e Ciências Humanas, Programa de Pós-Graduação em Filosofia, Florianópolis, 2015.A presente tese apresenta a teoria crítica tardia de Theodor W. Adorno por meio da análise dos diversos elementos que a compõe: sua dimensão política; seu público-alvo; seu objeto de crítica; suas críticas ao capitalismo, à racionalidade predominante na modernidade, à dominação da natureza e à vida danificada; seu projeto de emancipação e sua justificação normativa. Argumenta-se que, ao contrário do que defende a interpretação predominante, não houve uma substituição do objeto da crítica ao longo do percurso teórico do pensador frankfurtiano, da economia política à razão instrumental ou à dominação da natureza, mas sim uma complementação: de forma que a crítica ao capitalismo seguia sendo necessária, mas já não era mais suficiente como análise dos obstáculos que impedem a emancipação. O trabalho visa tanto expor o procedimento teórico crítico adorniano, a dialética negativa, como também questionar o diagnóstico de época e as tendências sociais observadas pelo autor frankfurtiano, e, na medida em que obtiver sucesso nessa dupla empreitada, almeja conseguir, ainda, estabelecer um diálogo crítico entre o autor, o seu tempo e o nosso.Abstract : This Doctoral Dissertation aims to present the late critical theory of Theodor W. Adorno by analyzing the various elements that compose it: its political dimension; its target audience; its object of criticism; its criticism of capitalism, of the prevailing rationality in modernity, of nature?s domination and of the damaged life; its emancipation project and its normative justification. It is argued that, contrary to the predominant interpretation defends, there was not a replacement of the object of criticism during the theoretical trajectory of the Frankfurtian thinker, from political economy to instrumental reason or to nature?s domination, but rather a complement: so the critique of capitalism was still necessary, but it was no longer sufficient as analysis of the obstacles to emancipation. The work aims to expose both the critical theoretical procedure, the negative dialectics, as well as to question the diagnosis of the time and social trends observed by the Frankfurtian author, and, in the extent that succeeds in this double endeavor, seeks also to be able to establish a critical dialogue between the author, his time and ours
Opportunistic Navigation with Iridium Next LEO Satellites
No full textThe concept of opportunistic navigation arises from the future demands that autonomous vehicles will require in order to navigate in a reliable and accurate way in GNSS-challenged environments. Specifically, GNSS signals are not robust enough against intentional jamming attacks and they are unencrypted, making them accessible by hackers and completely spoofable. Some alternatives that have been identified as timely sources of positioning are signals of opportunity, which cluster a broad spectrum including broadband LEO (Low Earth Orbits) satellite signals, AM/FM radio signals, Wi-Fi signals and even cellular LTE/4G signals, and which can be exploited for navigation although they were not transmitted for this purpose. Particularly, LEO satellite signals have inherent attributes that make them even more desirable for opportunistic navigation. First, their received signal power is around 30dB higher than GNSS signals since they are located approximately twenty times closer to the Earth’s surface. Second, they will be abundant in the following years since private companies are planning to aggregately launch thousands of broadband Internet satellites into LEO. Third, they will be diverse in frequency and direction since each broadband provider will deploy its satellites into unique constellations. Unfortunately, there are several challenges with using LEO satellite signals for navigation as it is discussed throughout this document. For instance, there is a need of having specifically designed receivers that can extract navigation observables from LEO satellites and, furthermore, the internal clocks of LEO satellites are not as precisely synchronized as GNSS satellite clocks, requiring the receiver to account for extra timing shifts. In this way, the present thesis addresses the problem of navigating opportunistically with Iridium Next LEO satellite signals by proposing a complete receiver architecture that allows to make Doppler measurements to satellite signals in order to obtain a PNT (Positioning, Navigation and Timing) solution.Outgoin
Desempenho do óleo de laranja no controle da cochonilha-do-carmim em palma gigante.
No full textDesde a sua introdução, em 2001, a cochonilha-do-carmim (Dactylopius opuntiae) já dizimou cerca de 100 mil hectares de palma gigante (Opuntia ficus-indica) no semi-árido paraibano. O presente trabalho teve como objetivo avaliar o comportamento de cinco concentrações de óleo de laranja aplicado em cladódios sobre a mortalidade de D. opuntiae, em condições de campo. A pesquisa foi conduzida em um campo de palma gigante infestado pela cochonilha-do-carmim no sÃtio rigideira, municÃpio de Monteiro, ParaÃba. Utilizou-se o delineamento experimental em blocos ao acaso (DBC) composto de seis tratamentos [doses de 0,3; 0,4; 0,5; 0,6; e 0,7% de óleo de laranja (Prev-am)] e água (controle) e cinco repetições. O óleo de laranja Prev-Am (Sodium tetraborohydrate decahydrate) controlou eficazmente a cochonilha-do-carmim, já a partir da dose de 0,3% e maiores potencialidades de eficiência foram observadas nas doses de 0,6 e 0,7%. Após 48 horas da aplicação do produto, foi observado que nas doses aplicadas adultos e ninfas do inseto, apresentavam-se dessecados em função da ação do produto que atua por contato. O produto não apresentou efeito mortÃfero sobre joaninhas (Cycloneda sanguinea e Scymnus intrusus), mas foi letal para larvas de Baccha sp. na dose de 0,7%.

ABSTRACT
Since its introduction, in 2001, the carmine cochineal (Dactylopius opuntiae) already decimated some 100.000 hectares of giant cactus pear (Opuntia ficus-indica) in semi-arid region of Paraiba. This study aimed to evaluate the behavior of five concentrations of orange oil, applied in cladodes on the death of D. opuntiae in field conditions. The research was carried out in a field of giant cactus pear infested by carmine cochineal on the site rigideira, Monteiro County, State of ParaÃba. The trial design used was blocks at random (DBR) composed of six treatments [doses of 0.3, 0.4, 0.5, 0.6, and 0.7% of orange oil (Prev-am)] and water as control and five repetitions. The orange oil known like Prev-Am (Sodium tetraborohydrate decahydrate) was effective against to carmine cochineal as early as the dose of 0.3% and higher potential for efficiency were observed at doses of 0.6 and 0.7%. After 48 hours of application of the product, which was observed at doses applied adults and nymphs of the insect, was dried according to the product action that acts by contact. The product had no lethal effect on ladybugs (Cycloneda sanguinea and Scymnus intrusus), but was lethal to larvae of Baccha sp. at a dose of 0.7%.

ABSTRACT
In the properties where fennel is grown, in the states of Bahia, Sergipe, Pernambuco and Paraiba, at the Northeast of Brazil, a high rate of usage of pesticides in the crop, aiming to control the aphid Hyadaphis foeniculi. The purpose of this study was to evaluate the effect of orange oil Prev-Am (sodium tetraborohydrate decahydrate), in the control of H. foeniculi aphid of the fennel crop. The trial was conducted in a fennel field located in Lagoa Seca Experimental Station, belonging to the EMEPA-PB. Forty-eight hours after the product has been sprayed, one flower of the umbel was collected and removed her aphids, which were placed in a "petri" plate from 9cm in diameter. As a following step, the insects were counted as part of two groups, considering the number of insects dead and alive, being tabulated for later analysis. The data were subjected to analysis of variance, using the experimental design of randomized blocks composed of six treatments (doses of 0.3, 0.4, 0.5, 0.6, 0.7% of orange oil (Prev-am) and pure water as check, with five repetitions. The data were submitted to the regression analysis. The orange oil (Prev-am) controls effectively H. foeniculi at the concentration of 0.3%, increasing the control up to concentrations of 0.6 and 0.7%. The product does not kill ladybugs (Cycloneda sanguinea) and can be used in programs for integrated pest management.

The apocryphal encyclical of Leo XIII: an episode of anticlericalism latin
No full textThis paper describes and analyzes an event apparently hitherto ignored by ecclesiastical historiography. I am referring to the publication of an apocryphal encyclical of Pope Leo XIII by several latinamerican newspapers in 1899. This paper is primarily a proposal to study the repercussions the pseudo document had in different countries in order to then be able to have a total view of the matter.Este artículo es un análisis de un suceso al parecer hasta ahora ignorado por la historiografía eclesiástica referido a la publicación en 1899 de una encíclica apócrifa del papa León XIII en diversos periódicos latinoamericanos.
