Retratos, instantâneos e lembranças: a trajetória e o acervo da fotógrafa Írica Kaefer, Marechal Cândido Rondon (1954-1990)
No full textEste é um estudo sobre fotografias e memórias feito a partir do acervo particular de Írica Kaefer, constituído pela Foto Kaefer, uma das primeiras casas fotográficas da então Vila General Rondon, com funcionamento desde meados de 1950 até 1990, período que define o nosso recorte temporal. Na perspectiva teórico-metodológica adotada, a fotografia é identificada como uma prática social de produção de sentido. A pesquisa, portanto, relaciona fotografia e memória a fim de discutir o processo de construção social e a relação dos sujeitos com a história local. As unidades culturais foram organizadas nas categorias espaço fotográfico, espaço geográfico, espaço do objeto, espaço da figuração e espaço da vivência, que serviram de base para a análise. Em síntese, após definidas as séries e as quantidades fotográficas analisadas, então entrevistas, textos, jornais e revistas fundamentaram a relação percebida entre a cultura fotográfica e a construção de memórias em Marechal Cândido Rondon/PR, no período 1954 a 1990382 f
Variations on the Author
No full text“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship

Palm and sole present different tonalities of cream, in ventral view. In preserved specimens, the palmar tubercle is more flattened.</p> <p> <i> <i>Advertisement call</i>.</i> Two different call types were recorded (Fig. 7 A–D), both of them from the same two individuals. Additional males, not recorded, also emitted both call types. We did not categorize these vocalizations as a single composed advertisement call because each one of the call types can be repeated for several minutes. The calls of type 1 (Fig. 7A) consist of one multipulsed note (Fig. 7C) with average duration of 0.248 ± 0.020 s (0.206– 0.292 s) and are composed by 72 ± 2 pulses (69–77 pulses). Calls type 1 are emitted in series (Fig. 7A) and are interleaved by silent intervals of 1.076 ± 0.162 s (0.621– 3.779 s). Calls type 1 have a mean dominant frequency of 3526 ± 170 Hz (3338–4264 Hz), low frequency of 3058 ± 119 Hz (2674–3234 Hz) and high frequency of 4478 ± 173 Hz (4277–4744 Hz).</p> <p>Different from calls of type 1, the calls of type 2 are arranged in bouts (Fig. 7B) of notes and have a duration of 1.9 ± 0.77 s (0.779– 3.191 s). The mean number of notes per call is 13 ± 5 (6–22 notes) and notes are 0.034 ± 0.001 s (0.010– 0.065 s) long in average. The duration of the silent interval between notes in call type 2 is 0.125 ± 0.028 s (0.085– 0.206 s). Notes are composed of 12 ± 1 pulses (9–14 pulses) (Fig. 7D). The mean dominant frequency of calls type 2 is 3450 ± 68 Hz (3220–4680 Hz), while the mean low frequency is 3200 ± 18 Hz (2961–3410 Hz) and high frequency is 4002 ± 91 Hz (3345–4680 Hz).</p> <p> <i> <i>Phylogenetic relationships</i>.</i> Our phylogenetic tree inferred from 559 aligned sites of 16S rRNA (Fig. 8) was partially concordant with Rojas <i>et al</i>. (2018a). All nominal species of <i>Amazophrynella</i> in our reconstruction formed well supported clades (PP Ż 0.95), excepted <i>A. siona</i>, and <i>A. teko</i>. <i>Amazophrynella bilinguis</i> <b>sp. nov.</b> was recovered as the sister taxon of <i>Amazophrynella</i> sp. 3 (<i>sensu</i> Rojas <i>et al</i>. 2018a) from Parque de Desenvolvimento Jatobá (Tapajós River, Pará, Brazil) with low support (PP = 0.74).</p> <p> Genetic distance between <i>A. bilinguis</i> <b>sp. nov.</b> and <i>Amazophrynella</i> sp. 3 was relatively low (p and K2P = 2%) compared to distances calculated between <i>A. bilinguis</i> <b>sp. nov.</b> and other <i>Amazophrynella</i> species that ranged from 3% (p) and 4% (K2P) (<i>Amazophrynella</i> sp. 2) to 14% (p) and 16% (K2P) (<i>A. siona</i>). <i>Amazophrynella bilinguis</i> <b>sp. nov.</b> presented 4% (p and K2P) genetic distance from samples of <i>A. bokermanni,</i> the nominal species that was placed closest to it in the phylogenetic tree. See Table 3 for genetic distances among all analyzed species.</p> <p> <i> <i>Distribution and natural history</i>. Amazophrynella bilinguis</i> <b>sp. nov.</b> is known only from Fazenda Taperinha (2°34’48.4” S; 54°22’16.6” W, 7 m a.s.l.) on south margin of the Amazon River, Municipality of Santarém, Pará State, Brazil (Fig. 9). However, it is likely that sampling efforts, which are historically scarce at that region, might expand the known distribution of this taxon.</p> <p>Like in other species within the genus, males of this species were found calling during the day, usually perched up to 10–40 cm above the ground on vegetation, fallen logs, branches or on leaf litter on the forest floor. Females and vocally active males were found near a stream and associated shallow ponds, where egg deposition and tadpole development may occur. After collection, a pair (female = INPA-H 39779, SVL = 20.8 mm; male = INPA-H 39774; SVL = 15.4 mm) engaged in axillary amplexus inside a plastic bag in the improvised field laboratory (Fig. 4A and 4B).</p> <p> <i> <i>Etymology</i>.</i> The epithet " <i>bilinguis</i> " is Latin and means "bilingual".

John F. Kennedy telegram to Roosevelt
No full textJersey Homesteads (later the Borough of Roosevelt) was established in the 1930s as an agro-industrial cooperative community. It was established specifically for urban Jewish garment workers, many of whom had emigrated from Europe. President John F. Kennedy sent a telegram to the citizens of Roosevelt, New Jersey, apologizing for not being able to attend the memorial dedication in honor of former President Franklin Delano Roosevelt. (Jersey Homesteads became Roosevelt in 1945 in honor of the president.) President Kennedy expressed his gratitude to the people of Roosevelt for constructing the memorial, and commented that it will serve as a constant reminder of Roosevelt's good works
Logarithmic variance profiles and the corresponding f-1 spectra of temperature fluctuations in turbulent Rayleigh-Bénard convection
No full textWe report experimental results for the temperature variance 2(z) and the corresponding frequency spectra P(f) in turbulent Rayleigh-Bénard convection (RBC) in a cylindrical sample of aspect ratioT= D/L = 1:00 (D = 1:12 m is the diameter and L = 1:12 m the height). The measurements were conducted in the Rayleigh-number range 1011 < Ra < 1:35 1014 and Pr ' 0:8. For Ra = 1:35x1014, 2(z) could be described well by a logarithmic dependence on the vertical position z in a range of z 1 < z < z 2 with z 1 ' 70 and z 2 = 0:1L. Here L=(2Nu) is the thickness of a thin thermal sublayer adjacent to the horizontal plate where the heat flux (denoted by the Nusselt number Nu) is carried mostly by thermal diffusion. In the log layer, we found that the temperature spectra had a significant frequency range over which P(f) f with close to 1. As Ra decreased, increased so that the log layer became thinner. At Ra = 2:05 1011, z 2 < z 1 and therefore there was no range for a log layer. Correspondingly, the temperature spectrum near the horizontal plate did not have the f1 scaling form either

Mapping the Discipline of the Olympic Games An Author-Cocitation Analysis
No full textThe authors conducted an author cocitation analysis on prominent authors writing about the Olympics during the 1990s. Author cocitation is an established bibliometric technique that can be used to measure the relative similarities of topics written about by the cited authors. This enables a visual representation of the “intellectual space” of the discipline, in this case the Olympics, to be created for the period under review. So core and peripheral research areas are identified, along with their major contributors. The representation appears as a two-dimensional cluster-enhanced map. Subject expertise was then applied to the results to place labels on the generated clusters of authors and their topics
Estimation of central arterial pressure from the radial artery in patients undergoing invasive neuroradiological procedures
No full textBackgrounds: Central arterial pressure can be derived from analysis of the peripheral artery waveform. The aim of this study was to compare central arterial pressures measured from an intra-aortic catheter with peripheral radial arterial pressures and with central arterial pressures estimated from the peripheral pressure wave using a pressure recording analytical method (PRAM). Methods: We studied 21 patients undergoing digital subtraction cerebral angiography under local or general anesthesia and equipped with a radial arterial catheter. A second catheter was placed in the ascending aorta for central pressure wave acquisition. Central (AO) and peripheral (RA) arterial waveforms were recorded simultaneously by PRAM for 90-180 s. During an off-line analysis, AO pressures were reconstructed (AOrec) from the RA trace using a mathematical model obtained by multi-linear regression analysis. The AOrec values obtained by PRAM were compared with the true central pressure value obtained from the catheter placed in the ascending aorta. Results: Systolic, diastolic and mean pressures ranged from 79 to 180 mmHg, 47 to 102 mmHg, and 58 to 128 mmHg, respectively, for AO, and 83 to 174 mmHg, 47 to 107 mmHg, and 60 to 129 mmHg, respectively, for RA. The correlation coefficients between AO and RA were 0.86 (p < 0.01), 0.83 (p < 0.01) and 0.86 (p < 0.01) for systolic, diastolic and mean pressures, respectively, and the mean differences-0.3 mmHg, 2.4 mmHg and 1.5 mmHg. The correlation coefficients between AO and AOrec were 0.92 (p < 0.001), 0.87 (p < 0.001) and 0.92 (p < 0.001), for systolic, diastolic and mean pressures, respectively, and the mean differences 0.01 mmHg, 1.8 mmHg and 1.2 mmHg. Conclusions: PRAM can provide reliable estimates of central arterial pressure. © 2019 The Author(s)
