“We Are All the Sons of Abraham”? Utopian Performativity for Jewish–Arab Coexistence in an Israeli Reform Jewish Mimouna Celebration
Authors: Ben-Lulu Elazar , Shem-Tov Naphtaly 
Published: July 2024

Abstract

Mimouna is a North-African Jewish festival, which in the past symbolized good neighborly relationships between Jews and Muslims. Today, however, this festival has transformed into a neutralized interfaith encounter, resembling a culinary-focused musical show. The particular event explored in this case study was organized by an Israeli Reform Jewish congregation, which is a non-Orthodox liberal Jewish denomination. In this event, the congregation strived to reconceptualize the diasporic concept of this festival. In effect, the performance is a cultural appropriation that reveals the failures to turn this tolerant vision into a current local political reality. The performance is constructed as a marketing script to brand Reform Judaism’s liberal ideology agenda and its sociopolitical position in Israeli society. The endeavor to establish the Mimouna as a safe space for fostering interreligious discourse and dialogue exposed its ideological vulnerability, thus bringing to the forefront the conflictual relationship between the Jewish and Muslim Arabs in Israel.
Microwave-assisted extraction of acetosolv lignin from sugarcane bagasse and electrospinning of lignin/PEO nanofibres for carbon fibre production
Authors: Mkumbuzi Emmanuel , Bruce Sithole Bishop , van Zyl Werner Ewald 
Published: July 2024

Abstract
Sugarcane bagasse (SB) is an agricultural waste with massive potential as a source of lignin for the production of renewable materials. In this study, acetosolv lignin from SB was extracted efficiently and sustainably via microwave (MW)-assisted extraction within 10 min. Subsequently, acetosolv lignin was subjected to electrospinning into lignin nanofibres (LNFs) for carbon fibre production using an 85/15% w/w lignin/poly(ethylene oxide) blend ratio in a DMF solution after optimisation of suitable electrospinning parameters. The structural characterisation of lignin was accomplished via pyrolysis-gas chromatography with mass spectrometry, heteronuclear single quantum coherence, Fourier-transform infrared spectroscopy, size-exclusion chromatography, and thermogravimetric analysis while the electrospun LNFs were characterised by transmission electron microscope as randomly arranged fibres with diameters ∼15 nm. SB is a readily available and valuable source of lignin for facile MW extraction using acetic acid, while electrospinning was a fast and efficient method for the fabrication of LNFs.
Entre dos muertes. Escansiones y silencios en las primeras narraciones historiográficas acerca del 16 de junio de 1955
Authors: Besse Juan 
Published: July 2024

El trabajo explora los sesgos descriptivos sobre los sucesos del 16 de junio de 1955 presentes en las primeras narraciones historiográficas que se inscriben bajo el formato de divulgación conocido, en el mercado editorial, como ‘breves historias’. El foco del análisis está puesto en dos trabajos, publicados a mediados de los años ´60 por José Luis Romero y Tulio Halperin Donghi, y los modos en que esos escritos exponen el intento de golpe de Estado contra el segundo gobierno de Perón y describen los hechos del 16 de junio. Así, se repasan sucintamente las nociones de lugar y política de la memoria con el fin de discernir los niveles en que dichos conceptos son habitualmente abordados y, de ese modo, analizar la manera en que los silencios presentes en las escrituras académicas entretejen los estilos de transmisión intergeneracional presentes en esas breves historias sobre la vida política argentina. En consecuencia, pensar las escrituras como un componente fundamental de las políticas de la memoria.

Assistência e Poder: as Sociedades Portuguesas de Beneficência nos municípios do extremo sul do Rio Grande no século XIX
Authors: Chaves Larissa Patron 
Published: July 2024

Este trabalho objetiva apresentar investigação sobre as Sociedades Portuguesas de Beneficência do Rio Grande do Sul em perspectiva comparada no período que compreende os anos de 1854 a 1910. Trata do estudo das Instituições de Beneficência Portuguesa no extremo sul do Brasil no século XIX no que refere a constituição e formação de elites regionais em quatro municípios: Porto Alegre, Rio Grande, Pelotas e Bagé. A Sociedade Portuguesa de Beneficência é uma instituição hospitalar criada por imigrantes portugueses no Brasil e no mundo colonial português, a partir da segunda metade do século XIX, dependente do pagamento e de doações advindas, normalmente, dos seus associados. Na Província, as funções primordiais das beneficências pautavam-se pela promoção da representação pública dos imigrantes como indivíduos de boa educação e cultura. Ao abordar a constituição das instituições nas cidades supracitadas, em suas ações representativas, percebeu-se que as Sociedades procuraram ressaltar valores ideológicos que remetiam a sua identificação enquanto portuguesas nas comunidades locais, ao mesmo tempo que, na evidencia da ligação com a formação de elites, a distinção e a possibilidade de emergência como poder. A partir de suas representações, as Instituições de Beneficência declararam a sua sujeição a cultura compartilhada reforçando o vínculo entre assistência, caridade e poder e constituindo um panorama social singificativo nas cidades do extremo sul do Brasil.

Authors: Michelon Francisca Ferreira 
Published: July 2024

O projeto de pesquisa As funções e os sentidos do registro fotográfico sobre o trabalho, durante o século XX, no Rio Grande do Sul, lotado no Departamento de Museologia, Conservação e Restauro do Instituto de Ciências Humanas da UFPel realizou levantamento em coleções e acervos fotográficos em várias instituições do Estado no qual a temática sobre o trabalho pudesse estar presente, assim identificada ou não. Um dos resultados foi localizar o que há nas instituições de documentação e memória e observar o tratamento de conservação e disponibilização dos acervos, com vista a estabelecer um catálogo de identificação. O recorte temporal abrange aspectos técnicos das possibilidades que a fotografia adquiriu a partir do desenvolvimento da emulsão fotoquímica com meio ligante em gelatina (inventada no século XIX, mas dominante, pela sua funcionalidade, a partir do seguinte). O projeto pretendeu conceituar, de forma expandida e a partir da empiria, o que é a fotografia do trabalho no Rio Grande do Sul, no século no qual se estabeleceu e se extinguiu um processo de registro visual cujo fundamento foi o da analogia. O trabalho permitiu observar o exercício de práticas que são reflexos das políticas institucionais e que redundam sobre a conservação desses acervos.
State- and circuit-dependent opponent-processing of fear

Published: July 2024

The presence of valence coding neurons in the basolateral amygdala (BLA) that form distinct projections to other brain regions implies functional opposition between aversion and reward during learning. However, evidence for opponent interactions in fear learning is sparse and may only be apparent under certain conditions. Here we test this possibility by studying the roles of the BLA→central amygdala (CeA) and BLA→nucleus accumbens (Acb) pathways in fear learning in male rats. First, we assessed the organisation of these pathways in the rat brain. BLA→CeA and BLA→Acb pathways were largely segregated in the BLA but shared overlapping molecular profiles. Then we assessed activity of the BLA→CeA and BLA→Acb pathways during two different forms of fear learning - fear learning in a neutral context and fear learning in a reward context. BLA → CeA neurons were robustly recruited by footshock regardless of where fear learning occurred whereas recruitment of BLA→Acb neurons was state-dependent because footshock only recruited this pathway in a reward context. Finally, we assessed the causal roles of activity in these pathways in fear learning. Photoinhibition of the BLA→CeA pathway during the footshock US impaired fear learning, regardless of where fear learning occurred. In contrast, photoinhibition of the BLA→Acb pathway augmented fear learning, but only in the reward context. Taken together, our findings show circuit- and state-dependent opponent processing of fear. Footshock activity in the BLA → Acb pathway limits how much fear is learned.Significance StatementHere we identify a fear opponent process in the brain. We show that an aversive event can recruit distinct populations of neurons in the rat basolateral amygdala. One population projects to the central amygdala to promote fear learning. A second population projects to the nucleus accumbens to oppose fear learning. These nucleus accumbens projecting neurons limit how much fear is learned and are candidates for therapeutic targeting to minimize the amount of fear learned after a traumatic experience.

Published: July 2024

Проведенное исследование относится к работам по получению консолидированных материалов методом самораспространяющегося высокотемпературного синтеза (СВС) с последующим компактированием горячих продуктов (СВС-компактирование). Методом СВС-компактирования механически активированных смесей порошков Ni и Ti получены беспористые образцы никелида титана диаметром 70 мм и толщиной 8 мм. Горение смеси Ni + Ti проводили в реакционной пресс-форме без предварительного нагрева и защитной среды. Исследовано влияние механоактивации в шаровой мельнице на характеристики смесей и параметры горения. Анализ микроструктурных характеристик показал, что увеличение реакционной способности МА-смесей Ni + Ti и осуществление экзотермического взаимодействия в режиме СВС обусловлены уменьшением размера кристаллитов в частицах Ni, увеличением в них плотности дислокаций и образованием композитных частиц Ti—Ni. Максимальная температура горения реакционной смеси — 1 150 °C, средняя скорость горения — 3.5 см/с. Основными фазами синтезированного сплава являются Ti2Ni, NiTi и Ni3Ti. Прочность образцов при сжатии — 1 350 МПа, микротвердость по Виккерсу — 11.1 ± 1.2 ГПа.
The conducted research relates to the works on obtaining consolidated materials by the method of self-propagating high-temperature synthesis (SHS) with subsequent compaction of hot products (SHS compaction). By the method of SHS compaction of mechanically activated mixtures of Ni and Ti powders, pore-free samples of titanium nickelide with a diameter of 70 mm and a thickness of 8 mm were obtained. The combustion of the Ni + Ti mixture was carried out in a reaction mold without preliminary heating and a protective environment. The effect of mechanical activation in a ball mill on the characteristics of the mixtures and the combustion parameters was studied. The analysis of the microstructural characteristics showed that an increase in the reactivity of Ni + Ti MA mixtures and the implementation of exothermic interaction in the SHS mode are due to a decrease in the crystallite size in Ni particles, an increase in the dislocation density in them and the formation of composite Ti–Ni particles. The maximum combustion temperature of the reaction mixture is 1150 °C, the average combustion velocity is 3.5 cm/s. The main phases of the synthesized alloy are Ti2Ni, NiTi and Ni3Ti. The compressive strength of the samples is 1350 MPa, the Vickers microhardness is 11.1±1.2 GPa. Keywords: SHS COMPACTION, MECHANICAL ACTIVATION, TITANIUM NICKELIDE,

Авиационные двигатели являются источником значительных выбросов парниковых газов, в частности CO2. В связи с ужесточением норм эмиссии ведутся поиски путей сокращения выбросов CO2 авиацией. Одним из наиболее перспективных путей достижения этой цели является применение топлив из возобновляемых источников, например из растительного сырья. Для моделирования рабочего процесса камер сгорания авиационных двигателей при сжигании биотоплив и их смесей с нефтяными топливами требуется знание физико-химических свойств таких топлив. В данной работе проведен обзор существующих методик расчета физико-химических свойств кислородсодержащих биотоплив, включающих в себя эфиры, спирты и кетоны. Представленные методики валидированы на веществах, выступающих в качестве биодобавок к авиационному топливу, и проанализированы с точки зрения точности расчета и простоты их применения для исследования рабочего процесса в камерах сгорания.
Aircraft engines are a source of significant greenhouse gas emissions, in particular CO2. Due to the tightening of emission standards, ways to reduce CO2 emissions from aviation are being sought. One of the most promising ways to achieve this goal is the use of fuels from renewable sources, such as plant materials. To simulate the working process of combustion chambers of aircraft engines when burning biofuels and their mixtures with petroleum fuels, knowledge of the physicochemical properties of such fuels is required. This paper provides a review of existing methods for calculating the physicochemical properties of oxygen-containing biofuels, including esters, alcohols and ketones. The presented methods are validated on substances acting as bioadditives to aviation fuel and analyzed in terms of calculation accuracy and ease of use for studying the working process in combustion chambers.
