60 anos do golpe de 1964 | Entrevista com Anderson da Silva Almeida
Authors: Da Silva Almeida Anderson
Published: January 2025

Anderson da Silva Almeida, Professor Adjunto da Universidade Federal de Alagoas, aborda em sua entrevista diversas questões relacionadas ao 60º aniversário do golpe de 1964 e suas repercussões. Ele destaca a importância da fala do presidente Lula, que busca reconstruir pontes com as Forças Armadas, evitando temas como a punição de torturadores. Almeida critica o desmonte das iniciativas de "Justiça de Transição" nos últimos anos, enfatizando que não há perspectivas de avanço nessa área. Sobre os arquivos da ditadura, aponta que a interrupção de projetos como o Memórias Reveladas afetou a pesquisa, dificultando o acesso a documentos históricos. No campo da educação, observa que o ensino sobre a ditadura é superficial, muitas vezes relegado a um módulo, e enfrenta uma competição de narrativas, especialmente da extrema direita. Também destaca a militarização crescente da política brasileira, evidenciada pela presença de militares em posições civis e na promoção de escolas cívico-militares, que reforçam uma cultura de controle e disciplina. Almeida conclui que o passado da ditadura ainda influencia a sociedade atual, revelando a persistência de desafios relacionados à memória e à justiça no Brasil.

Introduction: Systemic cystic angiomatosis is an exceedingly rare condition characterized by widespread cystic vascular lesions involving multiple organs. Its clinical presentation can be non-specific, often leading to diagnostic challenges. This report discusses the case of a 72-year-old female with a long-standing history of diabetes mellitus who presented with non-specific symptoms, ultimately diagnosed with systemic cystic angiomatosis after an initial misdiagnosis of vascular neoplasia. The role of advanced imaging techniques and a multidisciplinary, individualized management approach is emphasized.

Case Report: A 72-year-old female with long-standing diabetes presented with non-specific symptoms, including fatigue, fever, and rashes on the upper limbs. Initial physical examination revealed anemia and severe thrombocytopenia with a leukoerythroblastic blood picture. Despite unremarkable initial imaging studies, a bone marrow biopsy suggested vascular neoplasia. Further evaluation with a positron emission tomography (PET) scan revealed multiple non-avid lytic skeletal areas and cystic liver lesions, leading to a diagnosis of systemic cystic angiomatosis. A conservative management approach with danazol and eltrombopag was adopted. The patient later developed an acute-on-chronic subdural hematoma, a severe complication of the condition.

Conclusion: This case highlights the diagnostic complexity and the necessity for individualized management strategies in systemic cystic angiomatosis. It underscores the importance of considering rare diagnoses when faced with non-specific symptoms and atypical laboratory findings. Advanced imaging techniques, such as PET scans, and a multidisciplinary approach are crucial for accurate diagnosis and effective management of this rare condition.

Introduction: Chronic wounds pose a significant burden on patients’ physical and mental well-being and significantly raise health-care costs.

Case report: We report healing with VG111 application alone in a case of chronic wound in a patient who sustained a shell injury to the heel 35 years prior in 1988. Despite conventional wound care and multiple surgeries, the wound persisted. Application of VG111 resulted in complete healing of the wound within 3 months and restored the patient’s ability to walk normally as shown by repeat X-ray post 2 years of healing.

Conclusion: The management of non-healing chronic wounds pose major challenges in clinical practice. This novel formulation may offer a potential solution for patients with chronic wounds.

Introduction: Giant cell tumour or osteoclastoma is benign, locally aggressive tumor with bone destruction and with malignant potential. It accounts for 5% of all primary bone tumor and occurs in skeletally mature individuals in the age group of 30 to 45 with peak incidence in the 3rd decade. GCT is more common in females. It is usually a solitary lesion and typically involves epiphysio-metaphyseal region. Common sites involved are Distal end of Femur, proximal end of Tibia, distal end of Radius, upper end of Humerus, lower end of Tibia and other sites are hand,spine and Pelvis.

Case Report: A 44 year old male presented with the complaints of pain and swelling over the right wrist for the past 3 months. He was diagnosed as bony giant cell tumor of right distal radius for which right distal radius wide excision was done. Ipsilateral proximal fibular autograft of appropriate length was used to reconstruct the defect. The graft united well with reasonable preservation of range of motion of wrist.

Conclusion: Giant cell tumor of distal radius can be managed by wide excision + reconstruction with proximal fibular autograft instead of arthrodesis. Reasonable range of wrist movements can be preserved.

Keywords: Giant cell tumor, excisional biopsy, proximal fibular graft, good functional outcome, Asian dynamic compression plate.

Introduction: This report describes the use of a combination of a retrograde femoral nail and distal femur locking plate for the treatment of an open intra-articular distal femur fracture in a 99-year-old female. The purpose of this report is to highlight that nail-plate fixation constructs can be performed percutaneously and expeditiously even in extremely old patients; therefore, patient age should not be a limiting factor in choosing this construct to allow for immediate weight-bearing.

Case Report: The patient was a 99-year-old female who presented to the emergency room after a fall. Plain radiographs demonstrated a comminuted supracondylar distal femur fracture with a sagittal intercondylar split (OTA classification 33A3.3). She was indicated for operative repair and was fixed with a combination of a retrograde Stryker T2 alpha nail and Stryker distal femur locking plate. This method was chosen to allow the patient to be weight-bearing as tolerated after surgery so she could immediately start work with physical therapy to work towards getting back to her pre-injury ambulatory status. At 3 months post-operatively, she had minimal pain, no difficulties with activities of daily living, and was ambulating with the assistance of a cane. At 9 months post-operatively, she was ambulating with a cane (pre-injury status). She did not report any pain, and her radiographs illustrated fracture site consolidation. Furthermore, her short musculoskeletal functional assessment score was the same as it was pre-injury (81).

Conclusion: This case supports the idea of using a nail-plate combination for repair of intra-articular distal femur fractures, even in the very elderly as the patient’s functional outcome data reached pre-injury levels. In addition, it allows even elderly patients to begin early weight-bearing and decreases complications related to lack of extremity use.

Introduction: Bony and ligamentous ankle injuries are some of the most commonly treated injuries by orthopedic surgeons. Open ligamentous ankle injuries without an associated fracture or dislocation are rare and to our knowledge have only sparsely been described in the literature. We present a case and successful treatment of an open lateral ankle injury with capsular rupture and ligamentous damage without fracture or dislocation in a 22-year-old female. Due to the rarity of this injury, there is not a standard treatment protocol.

Case Report: A 22-year-old female presenting presented with an open ankle injury while playing volleyball after a sudden varus and inversion force. An xX-ray obtained at an outside hospital showed no acute fracture or dislocation of the ankle joint. In the operating room, stress examinations showed a positive anterior drawer and a positive varus stress test. Heavy non-absorbable suture was used to repair the ruptured ligaments with the ankle capsule. Augmentation of the repair was performed with a suture anchor placed in the lateral aspect of the distal fibula. Subsequently at 6-months post -operative the patient returned to full weight -bearing and radiographs showed maintenance of ankle alignment with no radiographic or clinical signs of instability.

Conclusion: Open ankle injuries without dislocation or fracture are very rare. Therefore, an ample assessment should always be conducted with an understanding that the extent of the injury may be underestimated via static radiographs. Surgical repair is necessary for treatment and we have described one technique through which treatment of open lateral ligamentous ankle injury is possible.

Introduction: Surgeries in the occipitocervical and upper cervical region are always quite challenging and need adequate surgical experience and expertise. Especially in cases, where both anterior and posterior surgical access is required, complication rates could be significantly high. The transoral approach for the ventral pathologies of the upper cervical region has been previously described using the conventional open technique where post-operative morbidity is a concern. Moreover, problems such as dysphagia, risk of injury to the oral components, and surgical site infection are always an issue. In patients requiring a combined posterior approach, surgical morbidity, and post-operative recovery is always an area of concern. We describe a case report of upper cervical myelopathy managed under full navigation using a combined tubular transoral (minimally invasive) and posterior approach.

Case Report: A 74-year-old male patient presented with myelopathy and weakness in bilateral upper and lower limbs (MRC Grade 4/5) due to a cystic lesion at C1 causing ventral cord compression. A staged anterior (minimally invasive transoral tubular approach) – posterior procedure was performed under full navigation for decompression and stabilization of C1-C2. Postoperatively, the patient showed neurological improvement (MRC Grade 5/5) in all four limbs.

Conclusion: A 360° navigation-guided approach to the upper cervical spine is a safer and more effective procedure with less risk of neurological and vascular complications. Furthermore, combining minimally invasive access anteriorly to the odontoid ensures reduced surgical morbidity of the overall procedure.

Introduction: In this article, we report a unique case of head-stem dissociation in a metal-on-metal total hip replacement which utilized an Exeter stem. Although metallosis and pseudotumor formation are well recognized complications of metal-on-metal hip replacements, head-stem dissociations are rare with few being reported in literature. To the best of our knowledge, this case report is the first to report this occurrence in an Exeter stem.

Case Report: A 76-year-old male presented to the emergency department with pain and discomfort in his left hip triggered by a twisting movement while getting into bed. The patient described a “pop” in his hip upon turning and reported mild ongoing discomfort in his left hip for the past 4 weeks before this acute presentation. X-rays and Metal artifact reduction sequence magnetic resonance image (MARS) revealed head-stem dissociation along with pseudotumor formation. The patient successfully underwent a two stage revision with no perioperative complications.

Conclusion: This case report, to the best of our knowledge, is the first to report catastrophic failure of a metal-on-metal hip caused by trunnionosis and subsequent head-stem dissociation. We report successful management of this unique case and hope to highlight the complexities and challenges associated with metal-on-metal THR. This case report is aimed at raising clinical awareness of this rare complication which requires expert management for a successful outcome.

Affective Economies of Tuberculosis and the Circulation of Knowledge: Insights from the Memoirs of Will Ross
Authors: Goggins Sydney
Published: January 2025

ABSTRACT: Bridging affect theory and history of science scholarship, this paper illustrates how discursive practices around tuberculosis in the early twentieth century established an affective economy in which the circulation of shame and fear served to establish “responsible” and “irresponsible” patient collectives, which in turn shaped the production of biomedical knowledge. I analyze the circulation of these affects through a rhetorical analysis of two patient narratives about tuberculosis by Will Ross, the first nonphysician president of the Wisconsin Anti-Tuberculosis Association. Drawing on Sara Ahmed’s scholarship on the cultural politics of fear, Berlant’s critique of cruel optimism, and scholarship on the social history of tuberculosis, I place Ross’s texts within the affective history of tuberculosis. While Ross’s memoirs are cited in Rothman’s key text on the social history of tuberculosis, scholars have yet to situate his writings within the context of twentieth-century policy discourses and the affective economy that informed them. Through in-depth engagement with a previously overlooked primary source, I contribute to the historical literatures on tuberculosis and patient advocacy.

3D scanning can construct comprehensive information about objects. However, scanning scenes at the meter scale is costly and inefficient. For large-area objects with distinctive physical attributes or tasks emphasizing internal relational mapping, there is value in taking a few sampling points to establish the relative relationships of objects. In this work, we used a time-of-flight camera for point data construction, demonstrating the use of the method on a wall. Meanwhile, a method to achieve a multi-dimensional assessment of wall flatness using relative relationships with only one acquisition is demonstrated, which has the potential for applications integrated with robotic construction.

Published: January 2025

A compact temperature-insensitive high-energy Q-switch Nd:YAG laser is demonstrated based on vertical cavity surface emitted laser (VCSEL) side-pumping and a variable reflectivity mirror (VRM) output coupler (OC). With the optimization of the laser parameters, the laser delivers an output energy of 217 mJ operating at pulse repetition rate of 100 Hz with 7 ns pulse width and a peak power of 31 MW. The brightness is estimated to be 10.34×106MW/mm2/sr. The spatial beam exhibits a near-flat-top intensity distribution with good beam quality of M2∼2.3. The temperature stability is measured at full output energy, indicating an energy variation within 1.8% for the temperature range from 15°C to 35°C.
Near-perfect molecular absorption enabled by critical coupling in metamaterial
Authors: Dayal Govind , Pratap Dheeraj
Published: January 2025

The absorption and emission spectrum arising from the vibrational motion of a molecule is mostly in the infrared region. These fingerprint absorptions of polar bonds enable us to acquire bond-specific chemical information from specimens. However, the mode mismatch between the atomic-scale dimensions of the chemical bonds and the resonance wavelength limits the direct detection of tiny amounts of samples such as self-assembled monolayers or biological membranes. To overcome this limitation, surface-enhanced infrared absorption spectroscopy (SEIRA) has been proposed to enhance infrared absorption directly via local field enhancement. Here, we report on the near-perfect absorption due to molecular vibration enabled by critical coupling in the metamaterials. Our molecular metamaterial design consists of a thin molecular layer sandwiched between a structured metal layer on top and a continuous metal layer at the bottom that supports the gap plasmon mode. The measured and simulated infrared spectra of the molecular metamaterial show broad and narrow absorption bands corresponding to the metamaterial and molecular vibration modes. We show that vibrational absorption can be enhanced to near unity by tuning the structure’s molecular film thickness and periodicity. Our finding offers a systematic approach to the development of ultra-sensitive molecular sensors, high-Q thermal emitters, and molecular photonic devices.
Mid-infrared absorption spectroscopy for in-situ and spatially resolved measurements of nitric oxide in premixed ammonia-methane co-fired flames
Authors: Cui Bang , Ma Liuhao , Sun Bowen , Li Qing , Wang Yu
Published: January 2025

Laser absorption spectroscopy (LAS) is a well-established measurement technique for quantitative chemical speciation in a combustion environment. However, in-situ LAS measurement of nitric oxide (NO) in ammonia flames has never been reported in the literature. This is despite the community’s recent strong interest in carbon-neutral ammonia combustion and the associated NO formation problem. In this work, we demonstrate the development and validation of a mid-infrared laser absorption sensor for in-situ measurements of NO formation and evolution in premixed ammonia and ammonia-methane cofired flames. To achieve calibration-free and interference-free measurements, the sensor exploits the NO absorption feature near 1900.07 cm-1 using the techniques of both direct absorption spectroscopy and wavelength modulation spectroscopy. Special efforts were given to address the thermochemical non-uniformity along the light path which was shown to have notable effects on measurement accuracy. Detailed computational fluid dynamics modeling on the flame structure was performed along with theoretical spectral simulation to assist in the treatment of the non-uniformity effects. Comprehensive measurements were then performed in flames with different ammonia proportions and equivalence ratios, with results compared to data from probe sampling methods and kinetic modeling. The present work is the first demonstration of an in-situ mid-infrared LAS sensor for quantitative and spatially resolved NO measurement in ammonia flames.

The optimized system has a zoom range of 18-35.5 mm and distortion is less than 2%. It achieves wide-band parfocality (400-850 nm), meeting the usage requirements for 4 K resolution sensors. The system is designed with a spherical lens, and tolerance analysis indicates its suitability for mass production. Experimental results show that the system achieves a center resolution of 174 lp/mm and 104 lp/mm in the visible spectrum and NIR-I band, respectively, which significantly improves the resolution and sensitivity of the endoscope adapters.
All-fiber chirp tuning of ultrashort pulses via long chirped fiber Bragg grating pair

Published: January 2025

Chirp tuning of ultrashort pulses is crucial for nonlinear fiber amplification and nonlinear dynamics investigations. Here we demonstrate all-fiber chirp tuning via a chirped fiber Bragg grating (CFBG) pair. Two identically long CFBGs were placed reversely to cancel out most of their huge dispersion (∼40 ps/nm or ∼22.4 ps2 @1030 nm), while the controllable temperature gradient along them could be used for precise chirp tuning with a tuning range of ∼ps2, verified by dispersion measurement and ultrashort pulse broadening. This relatively large chirp tuning could be used in prechirp management in nonlinear fiber amplifiers, exemplified by the optical spectrum tailoring therein. In addition, we also show this precise chirp tuning capability could be very helpful for pulse temporal quality diagnosis, which is indispensable for seed pulse optimization. We believe this all-fiber chirp tuning technique would find wide applications in nonlinear amplification and ultrafast nonlinear dynamics investigations.
A simple method for generating flattop laser lines
Authors: Sun Haiyin
Published: January 2025

A simple and low-cost equilateral prism is placed in the path of a laser line. The prism breaks the divergent Gaussian beam into two sub beams, transposes the two sub beams and partially overlaps them. The overlapped beams form a flattop laser line with clean edges. The performance of this proposed method appears to be better than the currently used Powell lens method.
Light-regulated microRNAs shape dynamic gene expression in the zebrafish circadian clock

Published: January 2025

A key property of the circadian clock is that it is reset by light to remain synchronized with the day-night cycle. An attractive model to explore light input to the circadian clock in vertebrates is the zebrafish. Circadian clocks in zebrafish peripheral tissues and even zebrafish-derived cell lines are entrainable by direct light exposure thus providing unique insight into the function and evolution of light regulatory pathways. Our previous work has revealed that light-induced gene transcription is a key step in the entrainment of the circadian clock as well as enabling the more general adaptation of zebrafish cells to sunlight exposure. However, considerable evidence points to post-transcriptional regulatory mechanisms, notably microRNAs (miRNAs), playing an essential role in shaping dynamic changes in mRNA levels. Therefore, does light directly impact the function of miRNAs? Are there light-regulated miRNAs and if so, which classes of mRNA do they target? To address these questions, we performed a complete sequencing analysis of light-induced changes in the zebrafish transcriptome, encompassing small non-coding RNAs as well as mRNAs. Importantly, we identified sets of light-regulated miRNAs, with many regulatory targets representing light-inducible mRNAs including circadian clock genes and genes involved in redox homeostasis. We subsequently focused on the light-responsive miR-204-3-3p and miR-430a-3p which are predicted to regulate the expression of cryptochrome genes (cry1a and cry1b). Luciferase reporter assays validated the target binding of miR-204-3-3p and miR-430a-3p to the 3′UTRs of cry1a and cry1b, respectively. Furthermore, treatment with mimics and inhibitors of these two miRNAs significantly affected the dynamic expression of their target genes but also other core clock components (clock1a, bmal1b, per1b, per2, per3), as well as the rhythmic locomotor activity of zebrafish larvae. Thus, our identification of light-responsive miRNAs reveals new intricacy in the multi-level regulation of the circadian clockwork by light.

Representação das atividades e profissões femininas na lírica galego-portuguesa
Authors: Vieira Yara Frateschi
Published: January 2025

Tendo em conta as limitações impostas, por condicionamentos contextuais e formais, à presença das atividades e profissões femininas na lírica galego-portuguesa, o nosso intuito é oferecer um quadro da participação das mulheres, enquanto agentes, nas diversas estruturas de poder social e econômico na sociedade da época, através da sua correspondente representação nos gêneros literários da produção trovadoresca. Assim, dentro do âmbito do poder real e senhorial, destacam-se as atividades políticas e administrativas, por meio de referências a rainhas e a mulheres da alta nobreza, apresentadas como administradoras da casa e promotoras de círculos artísticos; no mesmo patamar nobiliárquico, as abadessas, administradoras dos mosteiros, são apontadas em cantigas de escárnio e maldizer. A representação das atividades domésticas e profissionais, no entanto, é fortemente condicionada pelo gênero poético: nas cantigas de amor, a mulher nobre paira sobre as necessidades da vida prática, no retrato idealizado da mulher perfeita e inatingível; nas cantigas de amigo, há destaque especial para a atividade materna, exercida pela mãe da jovem protagonista enquanto actante na relação entre a filha e o «amigo»; as cantigas de escárnio e maldizer, por sua vez, incluem um mais numeroso elenco de atividades domésticas e profissionais, tratadas de forma satírica e pejorativa, entre as quais se destacam as exercidas por trabalhadoras sexuais, como as prostitutas, concubinas e barregãs. De forma periférica, o trabalho rural é retratado, de forma idealizada, nas pastorelas.
Imagética feminina e amor de ouvido no Cancioneiro Geral: o caso de Sá de Miranda
Authors: Morán Cabanas Maria Isabel
Published: January 2025

Embora não tenha sido até agora objeto de atenção e a sua presença seja mesmo excecional, o chamado amor de ouvido (de oídas, na tradição crítica castelhana) aparece no Cancioneiro Geral, tal como acontece nos cancioneiros manuscritos galego-portugueses, em que certos trovadores (por exemplo, Pero Viviaez), dirigem as suas declarações sentimentais a senhoras não vistas, mas das quais ouviram falar. Sob uma perspetiva histórica, comparatista e intertextual, analisamos a procedência e a projeção do topos nos versos de Sá de Miranda recolhidos por Garcia de Resende. Na verdade, na coletânea lusa, onde também sobressai uma composição de Gregório Afonso à fama como causa de idealização da dama (ainda) não contemplada com os olhos, este adquire uma especial importância sobretudo por dois motivos. Um deles é a sua ligação com outro núcleo temático à volta do qual gira toda a produção do poeta do Neiva: o desdobramento da personalidade que amiúde provoca a dama ingrata e traidora, causando grande aflição no sujeito lírico e tornando-o mesmo inimigo de si próprio, sobretudo nos trilhos de Jorge Manrique. O outro é a sua inserção em duas esparsas em que, de modo análogo às cantigas de amor trovadorescas, se sublinha a falta de correspondência entre o ouvir que causou a paixão e o ver, mas num Quadro imagético novo, o qual será retomado e amplificado com mais elementos plenamente renascentistas noutra composição mirandina alheia ao Cancioneiro Geral. Nele destacam-se alusões tanto a traços congénitos da fisiologia humana (a surdo-mudez), quanto a figuras que remetem para o bestiário e a Bíblia (a sereia e a serpente), sobre cujos valores semânticos e simbólicos refletimos à luz do universo mítico, social e literário da época.

«Yo me estaba reposando»: notas a la fortuna de un romance de Juan del Encina y su posible influencia en la Noche oscura de San Juan de la Cruz
Authors: Laskaris Paola
Published: January 2025

El presente trabajo sondea los vínculos entre el romance «Yo me estaba reposando» de Juan del Encina, incluido en su Cancionero de 1496, que gozó de larga fortuna, según demuestra una tradición textual tan varia como articulada, y una de las cumbres de la poesía mística: Noche oscura de San Juan de la Cruz. Las afinidades entre ambos textos nos ayudan a profundizar en el papel de la poesía culta y popular del otoño de la Edad Media como fuente de inspiración para el carmelita, arrojando nueva luz sobre algunas claves de su lírica.

Motyw szaleństwa w opowiadaniu Wołodymyra Wynnyczenki "Ogoniasty" i powieści Kena Keseya "Lot nad kukułczym gniazdem"
Authors: Mychyda Serhij , Kobzej Natalia
Published: January 2025

Artykuł poświęcony jest analizie porównawczej opowiadania Ogoniasty Woło- dymyra Wynnyczenki i powieści Lot nad kukułczym gniazdem Kena Keseya, w których pojawiła się specyficzna, odmienna od wcześniejszych tradycji literacka realizacja odwiecznego tematu szaleństwa. Rzecz nie w niemądrej „głupocie” czy „Bożej odpłacie” za grzechy, ale w wywołaniu efektu konkretnych fatalnych okoliczności, którym człowiek nie jest w stanie się oprzeć. Szaleństwo głównych bohaterów ma podłoże społeczno-polityczne i jest rozpatrywane przez autorów w kontekście „chorej epoki”. Innowacyjność pisarzy jest oczywista, wiąże się ze specyfiką ruchów artystycznych: modernizmu i postmodernizmu. Bohaterowie analizowanych utworów występują przeciwko hipokryzji i dysharmonii społecznej. Ich szaleństwo nie jest ostatecznym stadium choroby, ale ucieczką, drogą do uzdrowienia i wglądu, ważnym przykładem osobistej transformacji,
A Socio-Historical Mapping of Translation Fields: A Case Study of English Self-Help Literature in Arabic Translation
Authors: Alqarni Abdullah , Altalidi Bandar , Sahari Yousef
Published: January 2025

This study advances the application of Pierre Bourdieu’s social field as a heuristic conceptual tool in the context of translation studies, offering a methodological framework that integrates socio-historical analysis with bibliographical research. By exploring the field of Arabic translations of English self-help literature in the Kingdom of Saudi Arabia (KSA) between 1982 and 2016, the article illustrates how Bourdieu’s conceptualisation of social fields can be operationalised to define the boundaries, agents, production, and practices within a translation field. A bespoke bibliographical database comprising 993 translated self-help titles was constructed to provide a detailed mapping of the field’s historical trajectory and production dynamics. Through this integration of theory and empirical data, the study demonstrates how field theory can enrich the analysis of translation as a social practice, revealing the interactions between translation agents and the socio-historical forces that shape the production of translations. The findings suggest that this integrated approach can serve as a heuristic model for the socio-historical analysis of translation fields across different language pairs, temporal periods, and geographic contexts, contributing to future research in translation sociology and translation bibliographies.
Restitution of Jewish Property in Northern Transylvania During the Early Postwar Years
Authors: Ionescu Stefan Cristian
Published: January 2025

The restitution of Jewish property in the multiethnic region of Northern Transylvania faced numerous challenges during the first post-Holocaust years as a result of the complicated wartime history, postwar demographics, legal status, interethnic dynamics, and occasional violence. Having the lowest rate of survival among all Jewish communities in Romania, most of the region’s Jews died during the deportation and did not return to their native places to claim their properties. This impacted the extent of restitution of individual private property. Some of the Aryanized property was restituted to the Jewish survivors or their heirs because the wartime beneficiaries fled the country or renounced posession since they were afraid of potential negative consequences. Part of the restitution took place through court litigation and this gives researchers a chance to assess the extent of Jewish success in obtaining restitution. The Supreme Court decisions in restitution cases show that the Jewish plaintiffs were completely successful in their litigation based on law 645/1945 that cancelled the transactions with property Aryanized during the Hungarian rule of Northern Transylvania. This was a much higher success rate, compared to the general share of success for Jewish litigation at the entire country level – around 66 %.
A micro-anatomical investigation of dark and light-adapted eyes of Chilades pandava (Lepidoptera: Lycaenidae)
Authors: Ling Jing , Chen Hong-Ye , Xu Tian , Huang Yi-Ting , Huang Da-Ming , Zheng Xia-Lin
Published: January 2025

Chilades pandava (Horsfield) (Lepidoptera: Lycaenidae) is a notorious defoliating pest of Cycas spp. (Cycadaceae) in the tropical and subtropical regions of the world. The primary visual receptors of butterflies are the compound eyes. To understand the perception of visual stimuli in Ch. pandava, the external morphology and internal microstructure of Ch. pandava compound eyes were examined using light and scanning electron microscopy. The number of ommatidia was approximately equal in both sexes, and the eyes of Ch. pandava are of the apposition type, with the crystalline cone directly connected to the rhabdom. Significant differences were observed in the length of the crystalline cone and the width of retinula cell nucleus and crystalline cone under light-adapted conditions compared to those under dark-adapted conditions. Under light-adapted conditions, pigment granules moved to and remained below the crystalline cone and were near the rhabdom. In contrast, under dark-adapted conditions, pigment granules moved to the distal end of ommatidia, near the cornea, and exhibited a more spatially distributed pattern. These results provide essential information for exploring the poorly understood sensory ecology of butterflies in the family Lycaenidae.

When zinc hydrometallurgy is used to treat zinc oxide dust (ZOD), the fluorine (F) and chlorine (Cl) in the dust interfere with zinc electrowinning. To investigate the effectiveness of F and Cl removal from ZOD by different alkaline washing methods. Under the condition that 16 g/L Na2CO3 was mixed with 6 g/L NaOH in equal volume 1:1 and reacted with the dust under the optimum condition of the liquid-solid ratio of 5 mL/g for 2 h at 70 °C, final pH of 10, and stirring intensity of 400 rpm, the dechlorination of cloth bag zinc oxide dust (CBZOD) and boiler zinc oxide dust (BZOD) were 94.81 % and 90.63 %, respectively, and the defluorination were 84.81 % and 24.50 %, respectively. To further reveal the reasons for the difficult removal of F from ZOD, a step extraction method and physical phase analysis of residue were used, which resulted in more than 98 % removable fluoride in CBZOD and up to 56 % insoluble residue in BZOD. Therefore, it is obvious that the removal effect is better due to the presence of large amounts of removable fluoride and chloride in CBZOD; the F states and percentage of insoluble fluoride are main reasons affecting the removal of F.
Kelet-európai menekültek a 11–13. századi Magyarországon
Authors: Márta Font
Published: January 2025

Contrary to the general belief about the Middle Ages, mobility within one’s country was part of everyday life. Fleeing from an attack from outside the border or a dynastic conflict was not a rare phenomenon either. Dynastic conflicts spurred the losing party to attempt to regain its former position. Fleeing was also accompanied by a request for help, which they could hope for from relatives or neighboring dynasties. Narrative sources of the time, which were created in connection with the ruler’s court, usually give news about such cases. We know much less about the refugees outside the dynasty. We obtain information about the elite of society, those who played a role in the affairs of the dynasty, in the secondary threads of the dynastic story. In the lower strata of society the protection of their lives and property led to fleeing. Compared to the events of the war, we hardly have any documentation on this. The survival of a small number of cases reported is accidental.
A magyar királynék hatalma az anyagi kultúra tükrében – jegyzetek egy könyv margójára
Authors: Gergely Kiss
Published: January 2025

The defi nition of queenship and queens’ power is a rather complex task, since it cannot be sharply separated from the interpretation and essence of royal power. The question of its characteristics is a serious challenge, since there are relatively few and rather heterogeneous sources and records available from the period in question, from 11th-14th century Hungary. From this perspective, this paper examines, in the context of a recently published book, how the study of material culture can help to defi ne queens’ power.
Érzékenységvizsgálat az Európai Unió Tanácsának döntéshozásában
Authors: PETRÓCZY Dóra Gréta , CSATÓ László
Published: January 2025

Az Európai Unió Tanácsa (korábban Miniszterek Tanácsa) az Unió egyik fő döntéshozó szervezete, amelyben minden országot egyetlen fő képvisel, akinek szavazási súlya az adott ország népességével arányos. A döntések meghozatalához számos szavazás során minősített többség szükséges, amely megfelelő számú és összlakosságú tagállam támogatását jelenti. A korlátokat és súlyokat az Unió bővülésével gyakran újratárgyalták, ugyanakkor Nagy-Britannia kilépésével nem módosultak. Kutatásunkban az egyik legelterjedtebb hatalmi index, a Shapley--Shubik index segítségével elemezzük, hogy a két korlát változtatása hogyan befolyásolná az erőviszonyokat. Vizsgáljuk az Európai Unió döntésképességét és a tagállamok befolyásának egyenlőtlenségét is. Eredményeink szerint Magyarország szavazati ereje alig csökkenthető az összlakosságból való 2,17%-os részesedése alá. Ugyanakkor 15 tagállam egyetértésének megkövetelésével nem lehet magasabb 3%-nál, és kisebb tagállamkvóta esetén sem emelkedhet 3,5% fölé.
