Published: December 2024

Abstract
Various heat pipe-cooled reactors have been conceptualized and designed in recent years, ranging from kilowatts to megawatts, suitable for remote and extreme environments. However, existing designs employ monolith cores, which are saddled with heat transfer deteriorations due to thermal expansion and subsequent deformations are some of the key challenges facing monolith heat pipe reactors. Addressing this, a novel 300 kW heat pipe has been designed by introducing lead liquid instead of the monolith. A comprehensive Monte Carlo neutronics analysis of the designed core has been conducted including its thermal analysis. The core design comes with the following parameters: fresh core excess reactivity of 2.9914 $ that can support a 10-year life cycle, and a negative temperature coefficient of −0.1648 pcm/K. The axial and radial peak power factors at critical states were calculated to be 1.67 and 1.35 respectively. Preliminary thermal hydraulics analysis shows maximum temperatures of 1044 K under normal operation and worst-case accident scenarios (3 heat-pipe failures) of 1,149.9 K. These temperatures are lower than the melting point of uranium nitride fuel and lower than the possible heat pipe boiling failure limit at 1,300 K. Thus, the possibility of fuel melting/heat pipe boiling accidents is avoided. A hypothetical criticality accident was simulated, assuming the core was flooded with water, leading to an increased fission rate. However, the implementation of three emergency rods in the core ensures the subcritical of the reactor.
Insécurité du logement et insécurité alimentaire dans l’Inuit Nunangat
Authors: Balla Ndegue Séraphin Guy , Hervé Caroline 
Published: December 2024

La crise du logement et l’insécurité alimentaires sont des préoccupations majeures dans les communautés inuites du Canada, et tout particulièrement au Nunavut. Pourtant, bien que les débats autour de ces questions soient particulièrement féconds, la corrélation entre les deux problèmes a jusque-là été faiblement adressée par les recherches anthropologiques. Sur la base des données collectées à Cambridge Bay, cet article montre que l’insécurité alimentaire a partie liée avec l’histoire coloniale qui aura sédentarisé les Inuits et bouleversé leur espace social alimentaire, ainsi qu’avec une conjoncture environnementale et économique fragile. Les Inuits se retrouvent aujourd’hui confrontés à la baisse des activités de collecte, aux changements climatiques, à la faiblesse des revenus et au problème de logement. Mais au cœur de tous ces problèmes aux racines structurelles, la vétusté et le manque de logements viennent aggraver l’insécurité alimentaire en ce qu’ils induisent des dépenses supplémentaires, la surpopulation des ménages et contraignent beaucoup d'Inuit à l’itinérance. Les solutions à l’insécurité alimentaire doivent donc, sans négliger les autres aspacts, prendre en compte la question du logement ; ce qui requiert aussi d’impliquer les Inuits eux-mêmes dans les décisions y afférentes.

Introdução: A frequência de sintomas de depressão entre profissionais da saúde durante a pandemia de COVID-19 foi alta. Contudo, existem poucas evidências que incluem trabalhadores de apoio, aqueles que não desenvolvem diretamente a assistência em saúde.
Objetivo: Identificar a prevalência da presença de sintomas de depressão e de seus níveis, bem como, os fatores associados em trabalhadores da saúde brasileiros durante a pandemia de COVID-19. Método: Trata-se de uma pesquisa transversal, analítica e quantitativa, realizada com 108 trabalhadores da saúde de janeiro a maio de 2021, por amostragem não probabilística. Aplicou-se a Depression, Anxiety and Stress Scale para identificar os sintomas de depressão. Os dados foram analisados por meio de frequências absolutas e relativas para variáveis sociodemográficas, relacionadas ao serviço de saúde e ocupação, autopercepção de saúde, fatores relacionados ao risco para COVID-19, histórico clínico e “Sintomas de Depressão”. Foram aplicados testes de associação e estimadas Razões de Prevalência com Intervalo de Confiança de 95%.
Resultados: A prevalência de sintomas de depressão foi de 51,9% (IC95% = 43,1%–63,7%), sendo que o nível extremamente severo foi mais frequente (16,7%, IC95% = 8,8%–22,5%), principalmente, entre trabalhadores que não atuam diretamente na assistência (35,7%), comparado aos que assistem os pacientes (12,9%). Destaca-se a prevalência de sintomas de depressão entre os trabalhadores com autopercepção de saúde regular/ruim/muito ruim (88,0%), diagnóstico de transtorno mental (81,2%), uso contínuo de medicamentos (63,0%) e uso de psicotrópicos (69,6%).
Conclusão: Os sintomas de depressão foram predominantes entre os trabalhadores da saúde em meio à pandemia, ressaltando-se níveis extremamente severos que ocorreram com maior frequência entre trabalhadores de apoio. Sinaliza-se a necessidade de se direcionar a atenção à saúde mental de trabalhadores da saúde conforme especificidades, principalmente, ocupacionais, a fim de minimizar a ocorrência de sintomas de depressão.
Meaning-focused grammar instruction: examining British, Chinese, French and Italian textbooks for teaching Chinese as a foreign language
Authors: Gabbianelli Gloria 
Published: December 2024

The present study seeks to provide an analysis of how grammar instruction is presented in four selected Chinese as a foreign language textbooks published in four different countries. It explores how each textbook presents grammar, and to what extent grammar activities are presented, in a meaning-use focused and contextualized way. Two research questions guided the analysis: How is grammar presented regarding grammar description and target language samples? To what extent are grammar exercises contextualized and meaning-use focused? The results show that the role of grammar is still conspicuous, and textbooks tend to provide more activities that focus on meaning-form relationships than communicative tasks, still focusing more on accuracy than on interaction and meaning-use relationships. Activities promoting interaction, communicative tasks and meaning-use focused integrated in the analyzed textbooks are still rare. The paper also highlights the importance of cooperation among teachers, researchers and authors in producing teaching materials.

Pergaulan Calon Suami Istri Pada Masa Pra Peminangan di Sawunggaling Wonokromo Surabaya
Authors: Hadi Abdul 
Published: December 2024

This article discusses the social interaction between the bride and groom prior their marriage in Sawunggaling Wonokromo, Surabaya. In Islam, as long as the couple has not legally tied knot of marriage, they are not allowed to meet, let alone to make sexual intercourse. Any sexual intercourse outside wedlock is considered adultery and a major sin in Islam. Even if a man and a woman have been engaged to each other, this does not legalize sexual intercourse as long they have not tied knot. However, in Sawunggaling Wonokromo, Surabaya, after a man and a woman engaged for marriage, they are allowed to meet, to chat and even to have sexual intercourse. This interaction is a token of love and the man will be responsible to whatever happening to his fiance. Certainly, this practice is contradictory to Islamic teaching. A man and a woman engaged to each other will only allowed to meet with the attendance of a member of family to avoid unlawful relationship.
[Artikel ini membahas tentang pergaulan calon suami istri pada masa pra peminangan di Sawunggaling Wonokromo Surabaya. Pergaulan calon suami-istri dalam masa pra peminangan yang berlaku di Kelurahan Sawunggaling adalah kedua calon diperkenankan bergaul bebas layaknya suami-istri seperti jalan-jalan berdua ke mana saja mereka suka, bincang-bincang berdua dan bahkan tidur sekamar juga ditolelir oleh masyarakat di sana. Pergaulan tersebut merupakan manifestasi kecintaan tehadap calonnya, dan si laki-laki akan bertanggung jawab dengan apapun yang akan terjadi terhadap tunangannya. Ada duaÂ faktor yang mempengaruhi pergaulan tersebut yaitu: Pertama, faktor lingkungan setempat yang memiliki kebiasaan memperkenankan calon suami-istri bergaul bebas. Kedua, faktor pendidikan masyarakat setempat, yang belum begitu paham terhadap hukum perkawinan Islam khususnya tentang peminangan (khitbah). Bentuk pergaulan calon suami istri pada masa pra peminangan yang terjadi di Sawunggaling Wonokromo Surabaya, dilarang dan diharamkan dalam syariat Islam. Islam hanya memperbolehkan kedua calon bertemu dan pertemuan tersebut harus didampingi mahram supaya tidak terjadi kemungkaran (fahishah).]
Ijtihad Umar bin Khattab Tentang Hukum Perkawinan Perspektif Kompilasi Hukum Islam
Authors: Abbas Rafid 
Published: December 2024

Umar ibn al-Khattab is a bold, strict, intelligent and influential companion of the Prophet Muhammad. He brought the combination these character when he converted Â to Islam. He accepted the texts of the Qur'an, but cautiously derived legal decision from prophetic tradition. He used to correlate the narrative of prophetic tradition with the Qur'an before arriving at a decision. He made a lot of jurisprudential decisions during his tenure as the second caliphs. On the other hand, Kompilasi Hukum Islam is a legal product of Indonesian Muslim. It serves as a legal basis for judges in religious court. It compiled Islamic jurisprudence from classic Islamic schools of law in the area of Islamic family law. There are similarities between the opinions of Umar ibn al-Khattab with the pronouncements in the Kompilasi. Among the similarities are the prohibition to propose a woman who are engaged to other man, the approval of a woman for her marriage, the prohibition of marriage without guardian, the prohibition of setting steep dowry, the prohibition of temporary marriage (mut'ah), and the introduction of pre-marital agreement.
[Umar bin Khattab adalah sosok manusia yang keras, kasar, cerdas, dari kekasaran dan kecerdasannya inilah yang mengantarkan dia masuk Islam. Dalam memahami nash-nash al-Qur'an, Umar dapat langsung menerima, namun terhadap menentukan suatu hukum dari hadis, maka ia akan sangat hati-hati, ia selalu menghubungkan nash as-Sunnah dengan al-Qur'an, tujuannya agar keduanya dapat diterapkan dalam kehidupan masyarakat Islam. Kompilasi Hukum Islam (KHI) jika dilihat dari sejarah penyusunannya adalah himpunan kaidah-kaidah hukum Islam yang ditulis dan disusun secara teratur dan sistematis, diambil dari berbagai kitab (pendapat para fuqaha/doktrin) yang dipergunakan sebagai referensi pada Pengadilan Agama. Terdapat kesesuaian antara ijtihad Umar bin Khattab dengan Kompilasi Hukum Islam, di antaranya adalah: Larangan seorang laki-laki meminang perempuan di atas pinangan orang lain sesuai dengan Kompilasi Hukum Islam yang tercantum dalam pasal 12 ayat 3 dan 4. Persetujuan calon istri. Hal tersebut tercantum dalam pasal 16 dan 17. Larangan pernikahan tanpa wali sesuai KHI sebagaimana yang terdapat dalam Pasal 14, 19, 20. Larangan memberi mahar terlalu tinggi sesuai KHI pasal 31. Diperbolehkan mengadakan perjanjian perkawinan sesuai dengan KHI Pasal 45. Larangan nikah mut'ah sesuai dengan ketentuan KHI dalam pasal 2 ayat 3. Dan Larangan menikah beda agama sesuai dengan KHI pasal 40 dan 44.]
Pandangan Pakar Medis RSUD Dr. Soetomo Surabaya Tentang Perkawinan Beda Rhesus Golongan Darah
Authors: Taufik Rinna 
Published: December 2024

This research is a bibliographical research to uncover the opinion of the medical experts of Dr. Soetomo Hospital about marriage with different type of blood rhesus and the Islamic law analysis on the view of the medical experts of Dr. Soetomo Hospital about marriage with different type of blood rhesus. The research shows the views of the medical experts of Dr. Soetomo Hospital that a marriage with different type of blood rhesus has two versions. The first opinion, marriage with different type of blood rhesus is not permissible since it may contain any risks on fetus. The second opinion, marriage with different type of blood rhesus may cause any risks on fetus, such as kidney failure, brain damage, to death. This study concludes that the provision of Islamic law on the views of the medical experts about the marriage with different type of blood rhesus shall be closed as in accordance with the division of the third sadd al-dhari'ah, it is originally reserved for things that are permissible and is not intended for cases lead to destruction. However, the damage of wasilah can sometime be greater than the kindness.
[Penilitian ini adalah penelitian lapangan untuk mengungkap pendapat pakar medis RSUD Dr. Soetomo Surabaya tentang perkawinan beda rhesus golongan darah, dan bagaimana analisis hukum Islam terhadap pandangan pakar medis RSUD Dr. Soetomo Surabaya tentang perkawinan beda rhesus golongan darah. Berdasarkan penelitian ini diperoleh hasil bahwa dari beberapa pandangan pakarÂ medis RSUD Dr. Soetomo Surabaya tentang perkawinan beda rhesus golongan darah ada dua pendapat. Pendapat pertama, perkawinan beda rhesus boleh karena tidak mengandung resiko apapun terhadap janin. Pendapat kedua, perkawinan beda rhesus golongan darah tidak boleh karena banyak mengandung banyak resiko terhadap janin, seperti gagal ginjal, kerusakan otak, hingga meninggal. Hasil penelitian ini menyimpulkan bahwa ketentuan hukum Islam terhadap pandangan pakar medis tentang perkawinan beda rhesus golongan darah wajib ditutup karena sesuai dengan pembagian al-dhari'ah yang ke tiga yaitu wasilah yang semula diperuntukkan untuk perkara yang mubah, tidak diperuntukkan untuk perkara yang membawa kepada kerusakan, namun terkadang wasilah tersebut membawa kepada kerusakan, yang mana kerusakan itu lebih besar dari kebaikannya.]

This is a field research which aims to determine: (1) How the equality of marriage within the descendants of family of Mas in Sidosermo, Wonocolo, Surabaya and Berbek, Waru, Sidoarjo; (2) and how the equality of marriage within the descendants of family of Mas in Sidosermo, Wonocolo, Surabaya and Berbek, Waru, Sidoarjo under the Islamic law perspective. Based on the interview, it can be stated that most of the Mas family in Sidosermo, Wonocolo, Surabaya strongly consider the equality of the candidate of husband and wife in terms of family and religion. This, for the Mas family, is a very basic thing to be fulfilled. This is because they believe that they are the descendants of the Messenger of Allah. Unlike in Berbek, the wedding tradition for the Mas in Berbek does not currently take into account of nasab from prospective husband or wife. The most important things are there is a match between bride and groom and they have a feasible science and a good moral.
[Penelitian ini bertujuan untuk mengetahui 1) Bagaimana pernikahan kesetaraan keturunan di keluarga para Mas Sidosermo Kecamatan Wonocolo Surabaya dan Berbek Kecamatan Waru Sidoarjo. 2) Bagaimana tinjauan hukum Islam terhadap pernikahan dengan kesetaraan keturunan dikeluarga para Mas Sidosermo Kecamatan Wonocolo Surabaya dan Berbek Kecamatan Waru Sidoarjo. Jenis penelitian ini adalah Field Research. Berdasarkan hasil wawancara yang diperoleh, dapat dinyatakan bahwa sebagian besar keluarga Mas di kelurahan Sidosermo Kecamatan Wonocolo Surabaya sangat mempertimbangkan kekufuan calon suami dan calon istri dalam hal nasab dan agama. Menjadikan nasab dan agama sebagai kriteria kafaah bagi keluarga para Mas merupakan hal yang sangat pokok yang harus dipenuhi. Hal ini disebabkan karena mereka merupakan keturunan Rasulullah saw. Berbeda dengan di Berbek, tradisi pernikahan para Mas di Berbek saat ini tidak memperhitungkan nasab dari calon suami atau istri. Yang paling terpenting adalah ada kecocokan diantaranya, ilmu agama dan akhlaknya. Pada generasi saat ini kriteria kafaah di Berbek adalah agama. Keluarga Mas di Berbek hanya mengutamakan kualitas agamanya karena orang yang mempunyai agama yang bagus, otomatis dia sholeh, dan berakhlak mulia dan tidak ada kekhususan dalam segi nasab karena itu merupakan prinsip zaman dahulu yang telah berubah di zaman sekarang.]
Pengasuhan Anak Menurut Hukum Islam
Authors: Junaidy Abdul Basith 
Published: December 2024

Divorce between husband and wife has consequences to child. Parental obligations to a child are not limited to the time of marriage, but continuing even if their marriage has been broken. The problem that arises is who between the two parents is more worthy of parenting. In principle, Islam provides provisions that mother is more worthy to nurture for a reason that mother is usually more loving than father. However, Islam as a religion with a rahmatan lil’alamin mision, sets a universal principle, namely the main requirement of a caregiver is to have an attitude of trust and ability. The term of trust (amanah) includes a good moral and not to damage the child's belief. Even, the non-Muslim caregiver is allowed as long as she is not concerned about damaging the child's belief. The term of “ability” requires a caregiver to spend time with the child. By this reason, the mother's position, for example, as a caregiver, can be replaced by a father if she is not trustful. Law on Marriage and Islamic Law Compilation (KHI) give strong emphasis on the trustworthy provision of a caregiver in the matter of maintenance and moral education to child. The Religious Courts is authorized to deprive the child’s custody of the untrust caregiver. In the matter of difference in religion, the Religious Courts is also authorized to decide whether it affects to the benefit of a child or not.
[Perceraian yang terjadi antara suami isteri mengakibatkan konsekwensi terhadap pihak ketiga, yaitu anak-anak. Kewajiban orang tua terhadap anak tidak terbatas pada saat perkawinan masih utuh, akan tetapi kewajiban itu terus berlangsung meski perkawinan mereka telah putus. Persoalan yang muncul adalah mengenai siapa di antara kedua orang tua itu yang paling layak untuk melakukan pengasuhan. Secara prinsip, Islam memberikan ketentuan bahwa ibu lebih layak untuk mengasuh karena alasan biasanya ibu lebih memiliki kasih sayang dibanding ayah. Namun, Islam, sebagai ajaran yang memiliki misi Rahmatan lil Alamin, menetapkan prinsip universal dalam hal ini, yaitu syarat utama pengasuh anak adalah memiliki sikap amanah dan memiliki kecakapan. Syarat amanah meliputi sikap moral yang baik dan tidak merusak agama anak. Pengasuh non muslim diperkenankan asalkan tidak dikhawatirkan merusak agama anak. Syarat kecakapan menuntut kesediaan pengasuh untuk meluangkan waktu untuk anak. Atas dasar itu, posisi ibu, misalnya, sebagai pengasuh bisa saja digantikan ayah jika ia tidak amanah. Dan penentuan amanah atau tidaknya seorang pengasuh ditetapkan oleh Pengadilan Agama.]
Key Components of Trauma-Informed Yoga Nidra
Authors: Luu Kimberley 
Published: December 2024

Abstract
Trauma exposure is universal to the human condition, with many affected individuals experiencing either posttraumatic stress disorder (PTSD) or subthreshold manifestations. Both scenarios can become functionally debilitating and collectively lay a heavy burden on individuals and society. Yoga nidra is one adjunctive treatment of growing interest, holding potential for its ability to alleviate symptoms of trauma, including hypervigilance, sleep disturbances, and disembodiment. However, yoga nidra practices can have re-traumatizing side-effects if not delivered conscientiously. For instance, adverse reactions such as overwhelming flashbacks, emotional distress, and extended dissociation have been reported as a result of yoga nidra practice. To prevent harm and maximize yoga nidra’s therapeutic potential, 10 key components of trauma-informed yoga nidra practice are presented: (1) safe(r) and comfortable environment; (2) personal autonomy, healthy boundaries, and consent; (3) skillful mindful awareness; (4) appropriate length and preparation; (5) adequate settling and externalization; (6) sleep permission; (7) self-chosen intention; (8) flexible rotation of consciousness and breath awareness; (9) embodied pairs of opposites; and (10) conscientious visualizations. These measures protect those living with trauma and have extended benefits for nonclinical populations as well. That said, some of these components may be adapted based on context, especially in settings where direct feedback is readily available and can be prioritized. Ultimately, thoughtful decisions must be made with the intention of optimizing the safety of and benefit to the practitioners under the facilitator’s care.
BIEM_CH: An Efficient Algorithm for Dynamic Rupture Simulation of Complex Fault Systems with Unstructured Meshes and Half-Space Green’s Function
Authors: Liu Yuhang , Qian Feng , Zhang Haiming 
Published: December 2024

Abstract
In this study, a fast 3D dynamic rupture simulation algorithm, named BIEM_CH (Boundary Integral Equation Method for Complex fault systems in Half-space), is presented. This algorithm, based on exact half-space Green’s functions, supports both structured and unstructured discretization schemes, allowing for the effective handling of a wide range of fault geometries, from simple to complex. Because of the semianalytical nature of the boundary integral equation method, the integral kernel (surface integral of the spatial derivatives of Green’s functions) and rupture processes can be computed separately, making BIEM_CH particularly suitable for applications requiring numerous forward simulations, such as dynamic source inversion, for which only the rupture process needs to be recalculated once the integral kernel is obtained. The performance of the algorithm has been significantly enhanced, achieving up to a hundredfold speed increase through the use of exact closed-form solutions for the time-domain half-space Green’s function and matrix operations leveraging graphical processing unit acceleration, resulting in dynamic rupture simulations that can be completed in a matter of seconds. Moreover, BIEM_CH maintains excellent stability when the mesh dimension does not exceed 375 m, irrespective of whether structured or unstructured discretization schemes are used. In addition, this algorithm demonstrates good agreement with other methods in benchmark exercises conducted by the Southern California Earthquake Center and the U.S. Geological Survey’s dynamic rupture code verification project.
