Authors: Zhang Tianyao , Zhang Zhaohui , Zhao Xiaoyan , Cao Can , Yu Yang , Li Xingyue , Li Ying , Chen Yan , Ren Qing
Published: April 2020

In this paper, we present the application of transmissive terahertz (THz) time-domain spectroscopy for determining molecular polarizability for three widely applied solvents: water, ethanol, and acetone. Molecular polarizabilities of those solvents are obtained from the refractive index by using the Lorentz–Lorenz equation. The measured THz molecular polarizabilities are comparable with theoretical values estimated with both the first principle calculation and the atomic polarizability additive model. The THz spectra are presented over frequencies ranging from 0.3 to 1.2 THz (

Published: April 2020

It is worth highlighting that, for the first time to the best of our knowledge, vertical profiles of atmospheric parameters and were measured at Lhasa, south of the Tibetan Plateau, using balloon-borne radiosondes. Based on the measurements, two new statistical models (Lhasa HMN and Lhasa Dewan) for estimating turbulence strength are proposed. Attention has been paid to evaluate the reliability of the two models to reconstruct vertical profiles of from a statistical perspective. The statistical analyses presenting the Lhasa HMN model are accompanied with lower bias, root mean square error (RMSE), and bias-corrected RMSE () than those of the Lhasa Dewan model, which implies the Lhasa HMN model can better reveal the nature of turbulence characteristics of Lhasa influenced by unique local weather conditions. In addition, the comparison between the Lhasa HMN model and measurements in calculating integrated astroclimatic parameters is carried out, and the result suggests that the performance of the Lhasa HMN model is reliable and satisfactory. The new reliable model offers new insight into the characteristics of optical turbulence at Lhasa and provides support for pursuing astronomical site selection in the Tibetan Plateau.
Picosecond pulse pumped supercontinuum generation in silicon waveguide with a weak continuous wave trigger
Authors: Li Guangkuo , Li Qian
Published: April 2020

We numerically demonstrate that picosecond pulse pumped supercontinuum (SC) generation in a silicon waveguide can be enhanced with the assistance of a weak continuous-wave (CW) trigger. The bandwidth of the resulting SC is greatly improved. The effects of two-photon absorption, free-carrier absorption, and free-carrier dispersion on SC generation in the silicon waveguide are studied. The optimized trigger position is close to the modulation instability peak. The results help us understand the details of SC generation in silicon waveguides in the presence of a CW trigger and noise. By tuning the wavelength of the CW trigger, we reach a good temporal coherence and intensity stability in the picosecond pulse pumped SC generation in a silicon waveguide.
Polarization-maintaining optical fiber with an anisotropic core compatible with the SMF-28 standard
Authors: Michalik Damian , Stefaniuk Tomasz , Kasztelanic Rafał , Buczyński Ryszard
Published: April 2020

We present the theoretical study of an all-solid highly birefringent fiber with an anisotropic core fully compatible with SMF-28 fiber and without use of external stress zones or air holes. We propose a fiber with a core composed of interleaved subwavelength layers of silica and germanium-oxide-doped silica. The optimized nanostructured fiber has a phase birefringence of1.42×10−4, and an effective mode area and numerical aperture similar to SMF-28 fiber. We predict coupling losses of 0.1 dB for bidirectional coupling with the SMF-28 fibers.
Simulation of ultrashort pulse laser drilling of glass considering heat accumulation
Authors: Wei Chaoran , Ito Yusuke , Shinomoto Rin , Nagato Keisuke , Sugita Naohiko
Published: April 2020

In accordance with the increasing demand for high-speed processing, the repetition rate of ultrashort pulse lasers has continued to increase. With the development of these lasers, there is a growing demand for the prediction of shapes processed at high repetition rates. However, the prediction of these shapes is a major challenge, because of the difficulty associated with the estimation of heat accumulation. In this study, we developed a simulation of ultrashort laser drilling in glass including heat accumulation calculation between pulses. In this simulation model, temperature is considered as an additional criterion of material removal, thus, the dependency of the repetition rate can be estimated. Two model parameters of laser absorption at high temperatures are investigated and determined by experiments under high environmental temperatures. Using the simulation model, high shape-prediction accuracy at high repetition rates was achieved and validated by comparison with experiments. This study may contribute to broadening the applications of high-repetition-rate ultrashort pulse lasers.
Background-free imaging of chemical bonds by a simple and robust frequency-modulated stimulated Raman scattering microscopy
Authors: Xiong Hanqing , Qian Naixin , Zhao Zhilun , Shi Lingyan , Miao Yupeng , Min Wei
Published: April 2020

Being able to image chemical bonds with high sensitivity and speed, stimulated Raman scattering (SRS) microscopy has made a major impact in biomedical optics. However, it is well known that the standard SRS microscopy suffers from various backgrounds, limiting the achievable contrast, quantification and sensitivity. While many frequency-modulation (FM) SRS schemes have been demonstrated to retrieve the sharp vibrational contrast, they often require customized laser systems and/or complicated laser pulse shaping or introduce additional noise, thereby hindering wide adoption. Herein we report a simple but robust strategy for FM-SRS microscopy based on a popular commercial laser system and regular optics. Harnessing self-phase modulation induced self-balanced spectral splitting of picosecond Stokes beam propagating in standard single-mode silica fibers, a high-performance FM-SRS system is constructed without introducing any additional signal noise. Our strategy enables adaptive spectral resolution for background-free SRS imaging of Raman modes with different linewidths. The generality of our method is demonstrated on a variety of Raman modes with effective suppressing of backgrounds including non-resonant cross phase modulation and electronic background from two-photon absorption or pump-probe process. As such, our method is promising to be adopted by the SRS microscopy community for background-free chemical imaging.
Finite-key analysis for round-robin-differential-phase-shift quantum key distribution
Authors: Liu Hang , Yin Zhen-Qiang , Wang Rong , Lu Feng-Yu , Wang Shuang , Chen Wei , Huang Wei , Xu Bing-Jie , Guo Guang-Can , Han Zheng-Fu
Published: April 2020

Since the round-robin-differential-phase-shift (RRDPS) quantum key distribution (QKD) protocol was proposed, it has attracted much attention due to its unique characteristic i.e., it can bind the amount of information leakage without monitoring signal disturbance. Recently, Yin et al. have developed a novel theory to estimate its information leakage tightly. However, the finite-sized key effects are not taken into account. Here, we fill this gap and extend the security proof of the RRDPS protocol to the finite-sized regime using post-selection technique. As a consequence, it’s predicted that the key rate of RRDPS in a finite-sized key scenario can be comparable to the asymptotic one, which is meaningful for the real-life applications.

Published: April 2020

We demonstrate the capability to measure the absolute power responsivity of optical fiber-coupled detectors at an expanded uncertainty of 0.1%, by direct comparison with a cryogenic primary standard. To facilitate synchronous power measurements, commercial all-fiber beam-splitters direct laser diode light simultaneously to the device under test and the primary standard. We investigate the use of single-mode, polarisation maintaining, and photonic crystal fibers to access the cryogenic standard, and report a reduction in the temperature dependent effective refractive index of these fibers of 0.1%, 0.15% and 0.3% respectively in going from room temperature to 5 K. We also evaluate the polarisation dependent loss of the beam-splitters, the stability of the beam-splitter ratio between the cryogenic detector and the device under test and the temporal and modal stability of the Fabry-Pérot laser diode sources. It is shown that the stability of the optical fiber beam-splitters limits the overall performance of the measurement system to an expanded uncertainty of 0.1%.

Field demonstration of time-bin reference-frame-independent quantum key distribution via an intracity free-space link
Authors: Chen Huan , Wang Jipeng , Tang Bangying , Li Zhenhua , Liu Bo , Sun Shihai
Published: April 2020

Free-space quantum key distribution (QKD) based on mobile platforms, such as satellites, drones, and vehicles, is considered a promising way to overcome the rate-distance limit without a quantum repeater. Real-time reference frame calibration is required in most recent implemented polarization encoded QKD systems due to the relative motion between sender and receiver. Although active compensations can be used to calibrate the reference frame, doing so increases the complexity of the system and reduces the key rate. To overcome this problem, the reference-frame-independent (RFI) QKD was proposed in which fixed deviations of the reference frame between the two parties are tolerated automatically. In this Letter, we report the experimental implementation of a time-bin encoded RFI QKD in an urban environment through free space. The quantum bit error rate for key-distill is as low as 1% over a 2 km free-space link with a total equivalent loss of 31.5 dB. Our demonstration shows that a stable RFI QKD can be implemented in the free-space channel.
Reconfigurable multifrequency and wide-angle directional beaming of light from a subwavelength metal slit with graphene metasurfaces
Authors: Ju Zezhao , Deng Ming , Wang Jian , Chen Lin
Published: April 2020

Directional beaming of light from a subwavelength slit surrounded with phase-gradient metasurfaces can be realized with very high efficiencies, but the available optical proposals suffer from narrow bandwidth after the fabrication process and cannot be reconfigured dynamically with switchable frequencies. Here we demonstrate reconfigurable multifrequency directional beaming by placing a graphene ribbon array at two sides of a subwavelength metallic slit. Each graphene ribbon works with the metallic film to fulfill the magnetic response, and the resultant reflection phase can cover full 0–2π range by changing the chemical potential of graphene. The on-axis and off-axis directional beams can be formed by properly arranging the chemical potentials of graphene ribbons to serve as meta-couplers between surface waves and propagating waves. Thanks to the negligible interaction between vertically stacked graphene sheets, the beaming frequencies and angles can be broadened by use of double layers of the graphene ribbon array.
Few-mode frequency-modulated LiDAR receivers
Authors: Fardoost Alireza , Ghaedi Vanani Fatemeh , Wen He , Li Guifang
Published: April 2020

We present a few-mode frequency-modulated receiver for light detection and ranging (LiDAR). We show that using a few-mode local oscillator (LO) with spatial modes at different frequencies at the receiver can significantly improve the performance of the LiDAR detection range. A preferred receiver architecture features LO modes with unequal frequency separations based on optical orthogonal codes (OOC) to allow range detection via cross correlation. The required signal-to-noise ratio (SNR) for the frequency-modulated continuous wave (FMCW) LiDAR decreases with the number of LO modes. This receiver can have a potential impact in the area of automotive LiDARs.

-switched with a saturable absorber. When the pumping rate is higher than the spontaneous emission rate, it is experimentally confirmed that the pulse firing rate can be fractionally locked with the pumping rate by controlling the pump power. The locking characteristics of the firing rate display a variety of complex plateaus that can be excellently manifested with the sine-circle map. From numerical analyses, the coupling strength can be verified to be effectively enhanced by reducing the duty cycle of the pumping rate.
Design of a Heat Pump Based Heater and Dehumidifier Device
Authors: Pozsa Ákos , Illés Tamás , Mészáros Károly Marcell , Szaszák Norbert , Bencs Péter
Published: April 2020

Many residential building use electrical heaters mainly in bathrooms, even as a supplement heating device. These devices typically operate at very high efficiency, since in most cases, electrical current is converted into Joule-heat by means of electrical resistances. The humidity of the air in bathrooms is often very high. Therefore, it would be useful to apply such heating devices, which not only increase the temperature of the air, but also reduces the absolute humidity of it. If a heat pump is used for heating purposes where both the heat absorber and the heat exchanger are placed in the same airspace, condensation occurs at a temperature below the dew point of the given air condition at the point of heat extraction thus some of the humidity precipitates. Along with this the absolute humidity of the air can be reduced (which is also recommended for hygiene reasons). Furthermore, due to the latent heat released during the condensation a significant excess of heat appears on the heat exchanger, increasing the heating efficiency over 100%. The design and operation of a heat pump heater operating on such a principle is described in this study, addressing the typical air-conditioning parameters, correlations, calculations performed for the design.

Published: April 2020

Kutatásunk során a mikrohullámmal intenzifikált Fenton-reakció alkalmazhatóságát vizsgáltuk húsipari szennyvíz kezelése esetén. A kísérletek során figyeltük a Fenton-reakcióhoz szükséges reagens (Fe2+ és H2O2) adagolási dózisának és a közölt mikrohullámú energiának a kémiai oxigénigény (KOI) csökkentésére (és így a szervesanyag-tartalom csökkentésére) gyakorolt hatását.A kutatási eredményeink igazolták, hogy a szervesanyag-eltávolítási hatékonyság az alkalmazott Fe2+/H2O2 aránytól és az összes közölt MW energiától is függ. Magasabb dózisú Fenton-reagens nagyobb mértékű KOI-csökkenést eredményezett, a mikrohullámú energiaközlés pedig képes az oxidációs reakció hatékonyságát növelni – magas közölt MW energia esetén adott KOI-érték csökkenéshez jóval kevesebb reagens is elegendő volt. A kísérletek során azt is igazoltuk, hogy a dielektromos veszteségi szögtangens mérésével a szervesanyag-eltávolítás pontosan és könnyen nyomon követhető.

Pinning Down the Past: Lesbian Politics and Queer Ecologies in The Duke of Burgundy
Authors: Church David
Published: April 2020

Peter Strickland’s film The Duke of Burgundy (2014) presents an all-female world of lepidopterists whose non-monetary economic exchanges consist of mounted butterfly specimens and whose interpersonal exchanges consist of BDSM roleplay. This essay explores how the film represents a thought experiment in reimagining lesbian-feminist history by reconciling divergent strands of feminist and lesbian politics that occupied opposing camps during the period of the film’s early-1970s setting. The film’s “soft” eroticism and depiction of a non-capitalist economy posits a seductive fantasy of what an all-female separatist world might have looked like, had the various clashes within second-wave feminism found a utopian middle ground over major issues like the shifting place of lesbians within the women’s movement, the acceptability of sadomasochism and pornography as expressions of women’s sexuality, and the ecological implications of queerness.
An Excess of Love
Authors: Jacobs Jason
Published: April 2020

In both the social sciences and pop cultural representation, gay men’s open relationships are consistently described according to a contradictory logic in which coupled gay men may enjoy non-exclusive sexual practices because they are able to separate sex from emotional attachment and only on the condition that they separate sex from emotional attachment. Since the emotional response to outside sexual partners that should not occur always is a threat, gay men are cautioned to institute and obey rules to produce and enforce a boundary or separation, in the interest of protecting primary coupled relationships. This article argues that the failure to forestall an emotional response outside, beyond, and despite the boundaries of the couple has an important ethical value in the post-Obergefell world of gay normalization. An excess of love, flaring up where it shouldn’t, holds open the possibility of other forms of community, sociality, and relationality.

Published: April 2020

We report on a Q-switched Yb-doped all-fiber laser based on a solution-processed Ag nanoplates saturable absorber. Optical deposition procedure is implemented to transfer the Ag nanoplates onto the fiber core area through the thermal effect. The saturable absorber is sandwiched between two fiber connectors, providing simplicity, flexibility, and easy integration into the laser oscillator. The modulation depth and saturation incident fluence are measured to be ~5.8% and ~106.36 μJ/cm2 at 1-μm region, respectively. Self-started stable Q-switched operation is achieved for a threshold pump power of 180 mW. The repetition rates of the pulse trains range from 66.6 to 184.8 kHz when the pump power scales from 210 to 600 mW. The maximum average output power is 10.77 mW, corresponding to the single-pulse energy of 58.3 nJ and minimum pulse duration of ~1.01 μs. To the best of our knowledge, it is the first time that the Ag nanoplates saturable absorbers are utilized in the 1-μm Yb-doped Q-switched fiber laser.

Plasmons, as emerging optical diffraction-unlimited information carriers, promise the high-capacity, high-speed, and integrated photonic chips. The on-chip precise manipulations of plasmon in an arbitrary platform, whether two-dimensional (2D) or one-dimensional (1D), appears demanding but non-trivial. Here, we proposed a meta-wall, consisting of specifically designed meta-atoms, that allows the high-efficiency transformation of propagating plasmon polaritons from 2D platforms to 1D plasmonic waveguides, forming the trans-dimensional plasmonic routers. The mechanism to compensate the momentum transformation in the router can be traced via a local dynamic phase gradient of the meta-atom and reciprocal lattice vector. To demonstrate such a scheme, a directional router based on phase-gradient meta-wall is designed to couple 2D SPP to a 1D plasmonic waveguide, while a unidirectional router based on grating metawall is designed to route 2D SPP to the arbitrarily desired direction along the 1D plasmonic waveguide by changing the incident angle of 2D SPP. The on-chip routers of trans-dimensional SPP demonstrated here provide a flexible tool to manipulate propagation of surface plasmon polaritons (SPPs) and may pave the way for designing integrated plasmonic network and devices.
Influence of a 2-km Swim on the Cycling Power-Duration Relationship in Triathletes

Rothschild, J, Sheard, AC, and Crocker, GH. Influence of a 2-km swim on the cycling power-duration relationship in triathletes. J Strength Cond Res 36(5): 1431–1436, 2022—Triathletes must cycle after swimming, and so, it is important to understand how cycling performance may be affected by prior swimming. Therefore, the purpose of this study was to determine the effects of a 2-km swim at a self-selected race-pace intensity on the cycling power-duration relationship. Eighteen trained triathletes (12 M, 6 F; 37.1 ± 10.6 years, V̇o
2max 54.8 ± 10.1 ml·kg−1·min−1) performed two 3-minute all-out cycling tests (3MTs) on separate days with one 3 MT immediately after a 2-km swim (swim-bike [SB]) and one without prior swimming (bike-only [BO]). The power-duration relationship was expressed as the total work done (TWD) and subdivided into end-test power (EP) and work done above EP. To assess swimming intensity, heart rate (HR) was continuously monitored during the 2-km swim and blood lactate was assessed on completion of the swim. End-swim lactate was 4.2 ± 1.8 mM, and mean swimming HR was 147 ± 18 b·min−1. The 2-km swim decreased TWD during the 3MT by 6% (BO: 62.8 ± 12.7 kJ; SB: 58.9 ± 13.4 kJ; p = 0.001) though neither EP (BO: 281 ± 65 W; SB: 269 ± 68 W; p = 0.102) nor work done above EP (BO: 12.1 ± 3.8 kJ; SB: 10.5 ± 4.2 kJ; p = 0.096) differed between trials. In conclusion, TWD while cycling decreases after a 2-km race-pace swim. Results from this study suggest that triathletes should determine racing cycling power following a simulated race-pace swim.
The FPÖ’s welfare chauvinism
Authors: Ennser-Jedenastik Laurenz
Published: April 2020

This paper applies recent theoretical arguments about the relationship between redistributive justice principles and welfare chauvinism to the case of the Austrian Freedom Party (FPÖ). These arguments hold that parties vary welfare chauvinist appeals according to the redistributive principles underlying social programs. Means-tested and universal benefits that produce high levels of native-to-nonnative redistribution are thus prime targets. By contrast, social insurance individualizes benefit claims and thus undercuts the group logic inherent in nativist arguments. The analysis confirms that the FPÖ’s welfare chauvinism is mostly targeted at universal and means-tested benefits. Where it is applied to social insurance programs, the purpose is typically to exclude immigrants from non-contributory elements and thus strengthen the insurance principle for non-citizens. The analysis extends beyond existing research by also examining the adoption of welfare chauvinism by the ÖVP and the implementation of such policies by the ÖVP-FPÖ coalition between 2017 and 2019.

Inequality: American Exceptionalism or Global Trend?
Authors: Knox Andrew
Published: April 2020

Has the precipitous rise in inequality in the United States since the 1970s been a primarily American phenomenon, or is it simply the most extreme example of a larger international trend? The authors in this syllabus have emphasized the uniqueness of American inequality - in part to draw attention to the importance of national policy, in part as a rhetorical appeal that inequality is not a necessary fact of modern life, and in part to argue against explanations that attribute rising inequality to skills-based technological change (SBTC) or “globalization.” According to Hacker and Pierson, the rise of inequality “has been substantially more meteoric in the United States than in other rich nations... The hyperconcentration of income in the United States... sets the United States apart from other rich nations, calling into serious doubt the usual explanation for America’s winner-take-all economy, SBTC.”1Therefore, American politics is to blame for rising inequality, not transnational economic or political trends. Increases in inequality in other nations, especially the Anglo-Saxon countries, they attribute to economic competition with, and interconnection to the U.S. Also, “these [English-speaking] nations have also generally emulated U.S. public policymore than other nations have.” But what is distinctly American about the policies that they refer to?
Guys Like Gauguin: A Legacy of Colonialism

Paul Gauguin’s body of work lives at the intersection of orientalist and primitivist myth. He had a conscious hand in creating the mythology surrounding his work; his imagination was the source for the fiction of both his own life events and depictions of non-Western cultures. Separating who Gauguin is as an artist from who Gauguin was as a man proves a difficult task. A large body of work exists dedicated to documenting and understanding Gauguin’s biography, investigating evidence that may or may not shed light on the truest or most honest version of Paul Gauguin.

This paper discusses the progression and evolution of the Islamic State of Iraq and Syria, also known as ISIS.  The author explains how the group has progressed since its conception, explores possibilities for its evolution in the future, as it relates to and affects the surrounding countries and the international arena.  The author examines the question of whether Charles Tilly’s “War Makes States” theory can be applied to the group in past, present, and future.  The author uses a combination of literature review, critical reading, and research to explain how ISIS follows Tilly’s thesis that states emerge over time from areas of violence and the actions of violent groups. The author concludes that, despite recent territorial losses, the Islamic State of Iraq and Syria is evolving towards statehood per Tilly’s model, and that this has ramifications for the rest of the world in that the international arena should act accordingly when dealing with the group in order to forestall this occurrence.
The Interpretive-Sensory Access Theory of Self-Knowledge: Empirical Adequacy and Scientific Fruitfulness
Authors: Rimkevičius Paulius
Published: April 2020

The interpretive-sensory access theory of self-knowledge claims that we come to know our own minds by turning our capacities for knowing other minds onto ourselves. Peter Carruthers argues that two of the theory’s advantages are empirical adequacy and scientific fruitfulness: it leaves few of the old discoveries unexplained and makes new predictions that provide a framework for new discoveries. A decade has now passed since the theory’s introduction. I review the most important developments during this time period regarding the two criteria: whether the theory’s six main predictions were supported, and whether the theory’s predictions contributed to new empirical studies. I argue that the interpretive-sensory access theory of self-knowledge remains empirically adequate and scientifically fruitful.
“Nero (artist)” in Fedor Dostoevsky’s Workbook of 1864—1867
Authors: Smirnova Ekaterina L.
Published: April 2020

The article examines the problem of attribution of an essay from F. M. Dostoevsky's workbook of 1864—1867 (Russian State Archive of Literature and Art. Fund 212.1.5. p. 10), titled “The Usurer”. The novelty of the study is in that Nero (the artist), a character who emerged from the writer’s knowledge and concept of Emperor Nero, for the first time becomes the subject of detailed analysis. Based on the evidence from the classical and early Christian writers, as well as on scientific and literary works written during Dostoevsky’s lifetime, the author makes an argument for Nero’s figure to be considered a junction of at least three elements. He is not merely Nero-the-artist, but also Nero-the-persecutor of Christians and Nero-the Antichrist. This image reveals a ramified network of extensive ties with the preparatory materials for an early draft of “The Idiot”. Thus, it augments the aggregate of B. N. Tikhomirov’s arguments regarding other records, characters, motifs and prototypes in this essay. It also support his theory regarding “The Usurer”, which states that it is not the author’s independent and unexecuted idea, but, rather, should be examined in the framework of the creative history of “The Idiot”, specifically, its initial stage.

Tecnologia e literatura: as narrativas transmediáticas
Authors: Martins Moisés de Lemos
Published: April 2020

Foi o regime literário que produziu o Ocidente. No nosso tempo, todavia, o regime literário perdeu centralidade. Hoje, a cultura tem uma predominância  tecnológica, sendo através deste processo de mediação que se exprime, cada vez mais, a vida contemporânea. Com efeito, os novos territórios, paisagens, atmosferas e ambientes tecnológicos levaram as comunidades humanas a circum-navegar sites, portais, blogues, videojogos, aplicações, repositórios digitais, museus virtuais, e também realidades virtuais implantadas em ambientes imersivos. Um tal processo teve como consequência a multiplicação dos conteúdos e a convergência de formatos, plataformas informáticas e linguagens. O movimento de aparelhamento tecnológico da cultura expandiu a experiência humana. Podemos falar, nestas circunstâncias, de uma galáxia de novos fluxos, ressonâncias, ritmos, cadências, sonoridades, durações, vibrações, que permitem a abertura das comunidades humanas à configuração de novas possibilidades de futuro. Entretanto, a expansão da experiência humana abriu também a possibilidade de novas narrativas sobre o humano. A essas narrativas damos-lhe o nome de narrativas transmediáticas, por se apoiarem na convergência dos média digitais. Este estudo interroga as narrativas transmediáticas, que se desdobram através de múltiplas plataformas. Procuramos saber em que medida estas narrativas constituem uma escrita criativa e literária, uma escrita que não responda apenas a necessidades de gestão e de comunicação política, nem se esgote na repetição, adaptação e propagação da mesma história.
A função política dos discursos sociais e suas implicações sobre a biografia
Authors: Rinaldi Débora , Cardoso Suliane Da Silva
Published: April 2020

Resumo: O presente artigo tem como objetivo realizar uma discussão acerca da função política dos discursos sociais, bem como de suas implicações para a construção biográfica. A análise parte do resultado de duas pesquisas que tiveram como objeto de estudo dois tipos de atividades profissionais: catadores de resíduos e chefes de gabinete. Ambos os estudos possuem caráter qualitativo, e foram conduzidos a partir do método de entrevistas narrativas biográficas, com a utilização da reconstrução biográfica de caso como método de análise. A partir de conceitos formulados pelos sociólogos Pierre Bourdieu e Alfred Schütz, discutimos de que forma os entrevistados instrumentalizam discursos sociais a fim de legitimar suas práticas, bem como construir uma identidade positiva de si mesmos, com impacto sobre a biografia.

Authors: Yilmaz Onur , Sagnak Yilmaz Zeynep , Balaban Emre , Candirli Celal
Published: April 2020

Objectives: Odontogenic keratocyst (OKC) and ameloblastoma are slowly growing and locally invasive tumors with high recurrence rate. The aim of this study was to investigate the clinicopathologic features of recurrent ameloblastoma and OKC cases, and evaluate outcomes of our treatments in terms of recurrence. Material and Methods: A total of 23 patients with confirmed recurrent ameloblastoma or OKC and treated in our clinic within eleven years period were reviewed retrospectively. Results: Eleven recurrent OKC cases and twelve recurrent ameloblastoma cases were included. Most recurrences occurred within five years after the initial treatment (69.6%). Enucleation had the highest recurrence rate among the first treatments (18/23). All recurrences were located in the mandible, with one exception (22/23). All recurrent OKCs were multilocular. Different histopathologic subtypes of ameloblastoma were seen in our study, follicular ameloblastoma was the most common (8/12). The mean diameter of the lesions was 4.3 cm (ranging from 2 cm to 7 cm). Statically significant relation was found between location and diameter of lesion and year of recurrence onset (p=0.004; p=0.026). We performed radical treatments in these cases (ten patients underwent marginal resections, and thirteen patients underwent segmental resection), and no recurrence was observed during the follow-up period. Conclusion: Previous inadequate surgical procedures were the most important cause of recurrence. Marginal or segmental resection with safety margins is the best method to treat recurrences of OKC or ameloblastoma cases.
The spatial-temporal fragmentation of live television video clips: analysis of the television production of the Eurovision Song Contest
Authors: Pérez-Rufí José-Patricio , Valverde-Maestre Águeda-María
Published: April 2020

Multicamera television production’s similarity to the video clip has become evident in the production of the EBU’s Eurovision Song Contest, where various musical numbers representing public television stations from the organizing countries compete against each other in terms of spectacularity and originality. The main objective of this research is to analyze several acts to identify such appropriation. We will apply a textual analysis to the audiovisual discourse of a sample chosen through subjective sampling. We divide our analysis into four sections: preliminary phase, formal audiovisual analysis, staging and performance. The investigation leads to the conclusion that the characteristic fragmentation of space and time of video clips can also be identified in live music videos. This fragmentation is seen in the break in spatial continuity, resulting from recreating sets on stage and the abstraction of the stage thanks to screens and an avant-garde composition shot. We also consider that the production imitates the time fragmentation and fast shot speed of the video clip.
Trend towards extreme right-wing populism on Twitter. An analysis of the influence on leaders, media and users
Authors: Pérez-Curiel Concha
Published: April 2020

The advance of populism in Europe and the positioning of this type of politics on the Web are both facts substantiated by scientific research. In this connection, a platform like Twitter serves as a stage for dissemination, interaction, mobilisation and building the personality of influencer/leaders and as a strategic tool for the selection of issues and for propaganda and fake news. The main objective is to know the impact that this communication model has on both digital users and the media, particularly in electoral processes. To this end, a quantitative-qualitative comparative content analysis, which studies the issue frame and the game frame, is performed on the personal Twitter accounts of Marine Le Pen (@MLP_officiel), the leader of Rassemblement National (RN) in France, Matteo Salvini (@matteosalvinimi), the leader of Liga Norte (LN) in Italy, and Santiago Abascal (@Santi_ABASCAL), the leader of Vox in Spain. In the context of the European elections held on the 26 May 2019, a sample of 2,187 tweets, user metrics (‘likes,’ retweets and comments) and their reproduction in the digital newspapers @lemondefr, @repubblica and @el_país are analysed. The initial results evince a strategic use of online tools, with a media and public response that reproduces the populist discourse of the far-right, to the point of making it go viral.

Published: April 2020

Flakes and instant groats products have become increasingly prolific in recent decades among groats products. The interest of consumers in this type of groats and groats products is primarily connected to their ability to be quickly prepared and good food and flavoring properties compared with traditional groats. Due to their balanced amino acid composition, the presence of mucous substances unique vitamin content, most of groats can be attributed to the products of dietary and restorative nutrition.In the given article the existing technologies of hulled oats grain processing into groats products were analyzed. Thepossibilities of using new breeding varieties of oats to improve existing technologies were analyzed. Advantages using nakedoat varieties for the production of groats and flakes were considered. It was found that the technologically expedient moisture content of pearled naked oats groats before steaming is 17-17.5 %. After steaming groats with this moisture yield of flaked groat estimated to range between 84,3-93,6 %. For substantiation of modes of preparing pearled groats to flaking determining of its impact on physical properties of the flaked groats were conducted. Flaked products obtained from naked oats characterized by high uniformity, however by fractional composition are smaller compared with control samples. The main their percentage (about 60-70%), obtained by overflow of sieves  3,0 mm and  1,5 mm. Thickness of obtained in the studied modes flaked products is in the range 0,4-1,1 mm. Flaked products obtained from naked oats by steaming oats groats with moisture content 19.1 % by indicator of thickness characterized as flaked groats for which the characteristic thickness is 0.7 to 0.9 mm. Mode of steaming groats at vapor pressure of 0.15 MPa with moisture content 17.5 % allows producing flaked products which correspond by the value of thickness of the control of classical oat flakes 0,4-0,9 mm. Decreasing moisture content of groats before steaming to 15.4 % allows producing thin flakes, values of thickness of which in the range of 0.4-0.7 mm. Except thickness, strength of flakes also depends on mass fraction of moisture. For flakes with higher humidity inherent strength is greater compared to a product with low humidity. The final moisture of oat flakes is normalized by regulations and must not exceed 12.0%.Waterheat treatment of pearled groats with further its flaking reduces the proportion of ashes of flaked products from 1.8 to 1.5%.
