Authors: Varlamova A. I. , Arkhipov I. A. , Sadov K. M. , Khalikov S. S.
Published: July 2020

The purpose of the research is determining the efficacy of the supramolecular complex of fenbendazole (SMCF) based on the nano-sized supramolecular delivery system with polyvinylpyrrolidone (PVP) against nematodes in sheep in a commission and production test.

Materials and methods. A commission test was carried out at Izmailov LLC in the Krasnoarmeysky District of the Samara Region in August 2019. The SMCF at a dose of 2.0 mg/kg by the active substance was given to sheep (30 animals) of different age. The substance of fenbendazole was used as the major drug at a dose of 5.0 mg/kg in 20 sheep. A group of 20 sheep who were not given the drug was a control group. The drug efficacy was recorded by the flotation method according to results of the coproovoscopic studies of sheep before and 16 days after the drugs were administered. The drug efficacy was calculated by a “control test”. The production test of the SMCF in gastrointestinal strongylatosis of sheep was carried out on 120 wether hoggs at the same farm. The SMCF was prescribed to sheep once at a dose of 2.0 mg/kg by the AS in a mixture with 0.3 kg of oatmeal stock feed (per animal) given for the whole group. The efficacy of the SMCF was recorded according to the results of the coproovoscopic studies before and 15 days after deworming.

Results and discussion. In the commission test of 70 sheep with combined infection, the SMCF with PVP at doses of 3.0 and 2.0 mg/kg by the AS showed 98.7% effectiveness against Nematodirus infection and 99.2% activity against other types of gastrointestinal Strongylata. In the production test, the SMCF at a dose of 2.0 mg/kg by the AS showed a 99.1 % effect against nematodirosis and 98.8% against other gastrointestinal strongylatoses.
Melancolía y duelo. El duelo de sí mismo: tratamiento de la dimensión irrepresentable de lo real de la muerte en el cine
Authors: Benhaim Michèle , Broda Vladimir
Published: July 2020

La investigación que denominamos “Melancolía y Duelo” afronta el desafío de representar el duelo de sí mismo en el cine. En efecto, varias películas de gran calidad estética tratan sobre el apocalipsis y plantean problemáticas filosóficas contemporáneas. ¿Qué pretenden mostrar sus directores al plantear la dolorosa pregunta sobre el final, la muerte, la irreversibilidad del tiempo? ¿Por qué razón compensan los horrores de ese impasse mortífero con imágenes de una belleza que roza lo sublime? ¿Podríamos inferir que la muerte de uno o de todos no se representa? O indagando más profundamente, ¿podríamos concluir que una muerte anunciada no se puede aprehender? Freud ya decía que “la muerte propia es, desde luego, inimaginable […]. En lo inconsciente, todos nosotros estamos convencidos de nuestra inmortalidad”. Sin embargo, tanto Lars Von Trier como Xavier Dolan, a su manera, ponen al descubierto ese “real” de la muerte anunciada o del tiempo regresivo, en particular en Melancholia (2011) y Solo el fin del mundo (2016).
Poner en crisis a la política, la ética y la estética
Authors: Bernateau Isée
Published: July 2020

Este trabajo analiza psicoanalíticamente el film póstumo de Pasolini, inspirado en la novela Los 120 días de Sodoma, del Marqués de Sade. La trama presenta el increscendo de violencia, que el cineasta italiano ambienta en un marco completamente diferente al del original. Se trata del final de la Segunda Guerra Mundial en Italia, durante la república de Salo, creada por Mussolini en el norte de Italia entre septiembre de 1943 y abril de 1945. A partir de ese escenario, se aborda la categoría de lo Real irrepresentable como metáfora de los campos de exterminio nazis.
Vivir sin fundar. Política y psicoanálisis, una vez más
Authors: Liotta Daniel
Published: July 2020

Aquí estamos tratando de esbozar los principios de un vínculo político liberado de las presuposiciones imaginarias y simbólicas que definirían la naturaleza de los sujetos políticos. En otras palabras: de un vínculo político que no estaría determinado por la “sociedad” y las identificaciones imaginarias y simbólicas que impone al vínculo político. Tal política, que describimos como minimalista, debe ser indiferente a todas las consignas sociales: debe negarse a basarse en ellas. Decidir pensar en política de esta manera es sacar las consecuencias de una lección de la historia: basar el vínculo político en otro (Dios, raza, sexo, dinero, etc.) siempre determina justificar desigualdades, exclusiones, incluso asesinatos en  nombre de este Otro y sus imperativos. Si rechazamos así cualquier fundamento político, ¿qué queda? Por un lado, el ejercicio de la igualdad y la universalidad de los derechos de los sujetos despojados de toda identificación social: deben llamarse “ciudadanos”; Por otro lado, el coraje de asumir un vínculo político sin la garantía de otro que encontraría este vínculo. Así, el minimalismo jurídico-político afirma que la conexión política de los ciudadanos tiene lugar en una no relación social: el principio de la conexión política es necesariamente la no conexión social. Sin embargo, concebir un enlace no subordinado a un significante maestro, tratar de “descomponer” el Otro y pensar en la relación en forma de no relación, es aprender de Lacan. Por lo tanto, es nuevamente confrontar la cuestión, tan a menudo estudiada, del vínculo entre política y psicoanálisis.
Comer para vivir, comer hasta morir. Subjetividad y voracidad
Authors: Moreno-Márquez César , De Mingo Rodríguez Alicia Mª
Published: July 2020

Tomando como base de reflexión La grande bouffe, de Ferreri (1973), el presente artículo se propone mostrar hasta qué punto el comer constituye en el mundo contemporáneo un perfecto emblema de la sociedad de consumo y de la propia subjetividad. Después de que se separa de su sentido y de su sensatez como necesidad de nutrición, el comer se torna obsesivo. En lugar de “comer para vivir”, nuestra voracidad e insaciabilidad (rasgos ya esenciales del ser humano) parecen abocar a un “comer hasta morir” o, como en el film de Ferreri/Azcona, a comer-para-la-muerte. Nos hemos convertido en tragones y glotones, en un delirio de exceso, como respuesta (absurda y, al mismo tiempo, lógica) a la imposibilidad de trascender la “ingestión” no sólo de alimento, sino de Todo. En este sentido, la última de las artes habría de ser el arte culinario, que deberá seducirnos para desear comer cuando ya no tengamos apetito. Por otra parte, desde el punto de vista ético, Ferreri/Azcona nos invitan a pensar, indirectamente, que mientras unos seres humanos mueren de inanición, nosotros morimos hartos en nuestra insaciable saciedad. El film de Ferreri se convierte, de este modo, en espejo muy actual del mundo contemporáneo y en una extraña apología irónica y triste, pero lúcida, -si se puede decir así- del seductor y mortífero arte de cocinar, que excita nuestra voracidad. Diez años después (1983), Creosota reventará, harto de comer, en El sentido de la vida.
Un país para comérselo. Identidad y gastronomía en el cine de Bigas Luna
Authors: Pavés Gonzalo
Published: July 2020

Bigas Luna fue, sin duda, uno de los cineastas más carismáticos, originales y brillantes del cine contemporáneo español. A lo largo de casi cuatro décadas de intenso trabajo creativo donde compaginó su pasión por la pintura con los diversos proyectos fílmicos, el cineasta construyó un universo cinematográfico donde fueron es posible distinguir algunos temas recurrentes. Uno de los más obvios y conocidos es su insistencia, casi obsesiva, en relacionar erotismo y gastronomía en muchas de sus películas. Sin embargo, se ha prestado menos atención al hecho de que en ese maridaje de sexo y comida existía un tercer concepto, mucho menos estudiado, que es el de identidad nacional. De esta forma, después de vivir cuatro años en EE.UU., Bigas Luna comenzó a elaborar un discurso identitario cuyas bases no eran políticas, sino pura y gozosamente gastronómicas. Lo ibérico, lo mediterráneo, lo español se representaron en sus películas utilizando, como metáforas, algunos de los platos o alimentos más típicos de la tradición gastronómica nacional. De este modo, la paella, el jamón, la tortilla, las aceitunas o el chorizo aparecen en su obra como símbolos que explican las raíces de la cultura en la Península Ibérica.
BEM ESTAR DAS CRIANÇAS NO ENSINO FUNDAMENTAL, LIVRE DE PRECONCEITOS:
Authors: Valentim Klibiana Airam Antunes , Simões Raquel Hora da Conceição
Published: July 2020

Os comportamentos nocivos entre as crianças do ensino fundamental, é um problema que atinge à todos os envolvidos na educação básica, tanto os profissionais da escola, quanto os familiares dos alunos, justificando a necessidade de ações educativas para alertar cada aluno do quanto à prática do preconceito é perigosa, evitando assim danos futuros às vítimas de intimidações sistemáticas. Este trabalho teve a pretensão de conscientizar as crianças da educação primária, quanto à importância do respeito entre os colegas, sem preconceito de raça, de cor, de sexo, de idade e de quaisquer formas de discriminação, conforme disposto no artigo 3º da Constituição Federal de 1988. Despertar a empatia e o respeito naqueles que estão começando a caminhada na aprendizagem, modifica e qualifica o contexto social de vivência diária, para além do ambiente escolar, alterando até mesmo as realidades que ultrapassam os limites emocionais e físicos, configurando o hábito do bullying, que pode evoluir para um cenário com resultados gravíssimos, dificultando a intervenção. Neste sentido, foi desenvolvido uma palestra para que cada educando percebesse que uma ou outra característica que ele desaprova no colega, pode ser uma particularidade inerente a ele mesmo, enfatizando que a diversidade além de ser normal, é fundamental para a elegância de viver. A exposição de ideias relacionadas a temática procurou demonstrar que a necessidade por atitudes contrárias às discriminações é urgente, que é natural ser diferente e que as desigualdades não são motivos para a comicidade, expondo as diversas maneiras erradas em tratar o amigo e até mesmo aos professores, desenvolvendo o repúdio pelas palavras ofensivas já dirigidas ao chefe de sala. Além de enfatizar o artigo 3º, inciso IV, da Magna Carta, o projeto contribuiu para assegurar o princípio da dignidade da pessoa humana, elencado no artigo 1º, inciso III, da Constituição, possibilitando a expansão da democracia na funcionalidade social pela pretensão de garantir o respeito e a proteção dos direitos coletivos e individuais. O método utilizado foi o qualitativo e dedutivo-indutivo.

Instrumental Learning and Cognitive Flexibility Processes are Impaired in Children Exposed to Early Life Stress
Authors: Harms Madeline , Bowen Katherine Shannon , Hanson Jamie Lars , Pollak Seth
Published: July 2020

Children who experience severe early life stress show persistent deficits in many aspects of cognitive and social adaptation. Early stress might be associated with these broad changes in functioning because it impairs general learning mechanisms. To explore this possibility, we examined whether individuals who experienced abusive caregiving in childhood had difficulties with instrumental learning and/or cognitive flexibility as adolescents. Fifty‐three 14–17‐year‐old adolescents (31 exposed to high levels of childhood stress, 22 control) completed an fMRI task that required them to first learn associations in the environment and then update those pairings. Adolescents with histories of early life stress eventually learned to pair stimuli with both positive and negative outcomes, but did so more slowly than their peers. Furthermore, these stress‐exposed adolescents showed markedly impaired cognitive flexibility; they were less able than their peers to update those pairings when the contingencies changed. These learning problems were reflected in abnormal activity in learning‐ and attention‐related brain circuitry. Both altered patterns of learning and neural activation were associated with the severity of lifetime stress that the adolescents had experienced. Taken together, the results of this experiment suggest that basic learning processes are impaired in adolescents exposed to early life stress. These general learning mechanisms may help explain the emergence of social problems observed in these individuals.

A Mobile Sound Localization Setup
Authors: Wasmann Jan-Willem , Janssen Arno , Agterberg Martijn
Published: July 2020

We present a mobile sound localization setup suitable for measuring horizontal and vertical sound localization in children and adult patients in the convenience of their own environment.In this paper, a mobile sound localization setup is described that can be used to measure a persons’ localization performance in a sophisticated way. With this mobile setup, researchers can travel to subjects, and studies are not limited by the willingness of participants to visit the clinic. In the setup, sounds are presented within a partial sphere in both the horizontal (-70o to 70o azimuth) and vertical (-35o to 40o elevation) plane. Participants are asked to indicate the perceived sound origin by pointing with a head-mounted LED. Head movements are recorded and instantly visualized (i.e. online target response plots). Depending on the research question, the setup can be adjusted for more advanced or simplified measurements, making the setup suitable for a wide range of research questions. The rationale for building this mobile setup was to test horizontal sound localization abilities (binaural hearing) and vertical sound localization abilities (monaural hearing) of children and patients who were otherwise not accessible for testing. In this setup loudspeakers are not visible and subjects are asked to indicate the perceived sound direction by a natural head-pointing response towards the perceived location. An advantage of the implemented pointing-method is the playful manner in which children are tested. They are ‘shooting’ at the perceived sound target location with a head-mounted LED and have fun while performing the test.
Who Bought All the Toilet Paper? Conspiracy Theorists Are More Likely to Stockpile During the COVID-19 Pandemic
Authors: Bai Hui
Published: July 2020

The current COVID-19 pandemic has changed many people’s lives. Some people have responded to the rising of the pandemic by engaging in panic buying behaviors, a phenomenon that has not been well-understood in the past. People who believe in these conspiracies may experience a heightened sense of powerlessness and vulnerability. As a result, they may be particularly susceptible to palliatively and compensatorily engage in the panic buying behaviors (i.e., stockpiling). Supporting this idea, two studies using data from the U.K. (cross-sectional) and the U.S. (longitudinal) show that people who endorse COVID-19 conspiracy theories are more likely to engage in stockpiling behaviors in the past as well as in the future.
Cheese: Importance and Introduction to Basic Technologies
Authors: Sharma Khanal Bal Kumari , Pradhan Monica , Bansal Nidhi
Published: July 2020

Cheese is a highly nutritious fermented milk product with diverse flavour and texture. When compared to whole milk (3-4% protein and fat), it contains 30-40% protein and fat along with other minerals and fat soluble vitamins. Fewer varieties of cheese are available in Nepal compared to the European and American regions. Due to increased awareness of the health benefits of cheese and expansion of cattle farming in Nepal, the demand and supply of cheese is in increasing trend. To overcome the milk holiday in the surplus season, cheese manufacturing could be an attractive venture. By meeting the quality standards set by national and international bodies, there may be huge opportunity for exporting the cheese. However, still many dairy manufacturers are not aware about cheese production technologies and their implications. Hence, this review is aimed at providing more general information on cheese, its ingredients and steps involved in cheese making.

Schrödinger and Planck oscillators: not quite the same physics for a modified Einstein solid
Authors: N. Miranda Enrique
Published: July 2020

In the statistical mechanics of quantum harmonic oscillators, the zero-point energy can either be included (Schrödinger oscillators) or omitted (Planck oscillators). For the usual results, the type of oscillator makes no difference but, looking more closely, it turns out that including or not this energy is not without consequences.                        A simple model is introduced that we called the modified Einstein solid (MES). In this model the frequency of the oscillators change with the volume of the solid, and this change is characterized by a certain value of the Grüneisen parameter. The specific heat is the same as in the standard Einstein model, but the pressure, equation of state and bulk modulus can be evaluated in the MES. Using Planck oscillators, the pressure shows an anomalous behavior in terms of the volume, and the bulk modulus becomes negative for certain temperature and volume values, which is physically incorrect. When Schrödinger oscillators are used, the bulk modulus is always positive. Therefore, the different behavior of both types of oscillators indicates that only Schrödinger oscillators lead to correct results.

Particle physics phenomenology with Python 3: $e^- + \bar{\nu}_e \to e^- + \bar{\nu}_e$ scattering in the Fermi theory
Authors: Domínguez Jiménez I. , Hernández Pinto R. J. , Rentería-Estrada D. F.
Published: July 2020

In this work, we develop an algorithm in Python 3 to compute the theoretical prediction of the electron and electron anti-neutrino scattering cross section using two different numerical methods: {\it i)} Riemann sums and {\it ii)} Monte Carlo integration. We compare the precision among these two methods and the theoretical result. Finally, the theoretical prediction is compared with the result obtained with MadGraph 5 which is commonly used to provide theoretical predictions for the LHC. With this project, we would like to encourage students to use programming languages as a tool for the study of new physics.

Published: July 2020

An integrative methodology for teaching science is proposed through the STEM methodology (Science-Technology-EngineeringMathematics).The STEM methodology provides students the opportunity to combine knowledge in an interdisciplinary and collaborative manner, allowing the development of creative and systemic thinking. As a model we propose the experimental reproduction of the Belousov-Zhabotinsky reaction (BZ), which is the standard prototype of non-linear chemistry, in addition we used the Python V2.7 programming software and the Jupyter platform for the computational reproduction of the BZ reaction. The STEM methodology could help the development of new competences for students, that is, it will provide them with tools to solve complex current problems that require of the interdisciplinarity
Confined free motion under a dipole potential

Published: July 2020

The classical motion of a particle in a dipolar potential, $U_{\hbox{dip}}(q) = - {k}/{q^2}$, and free motion along a curve in phase space are proven to be equivalent. We also prove that the singularity at $q=0$ in the dipolar potential is strong enough as to prevent the flow of particles from one side of the singularity to the other. This effect does not depende on whether the dipole potential is regarded as attractive ($k>0$) or as repulsive ($k<0$). All the proofs are given using the Hamitonian formalism, therefore they may be used for illustrating the power the Hamiltonian approach may confer in analysing different mecanical systems. The discussion is keep within the reach of advanced undergraduate or graduate students of Hamiltonian mechanics.
Do COVID-19 Policies Affect Mobility Behaviour? Evidence from 75 Canadian and American Cities
Authors: Armstrong David A. , Lebo Matthew J. , Lucas Jack
Published: July 2020

We construct a new measure of the aggressiveness of COVID-19 policies in 75 Canadian and American cities and estimate the effect of these policies on mobility patterns in each city. Using a new dataset of five municipal COVID-19 policy indicators for each of our 75 cities, combined with 11 provincial/state policy indicators, we estimate a daily measure of the “aggressiveness” of the provincial/state and municipal COVID-19 policy mix in each city. We then estimate the effects of these policies on subsequent mobility behaviour using dynamic time series models. We find strong evidence of policy effects on subsequent mobility behaviour, but few overall differences between Canadian and American cities. We discuss the significance of our findings both for COVID-19 policy research and for other comparative urban policy research in multilevel policy environments.
