Authors: Zakyia Imra , Shafii Mohammad Ali 
Published: March 2022

Telah dilakukan penelitian mengenai distribusi fluks neutron dalam persamaan difusi neutron multigrup satu dimensi.Â Jenis reaktor yang digunakan adalah reaktor cepat dengan teras berbentuk slab dan bahan bakar yang digunakan yaitu U-PuN. Penelitian ini menggunakan penampang lintang makroskopik di level sel bahan bakar sebagai masukan awal untuk 70 grup energi.Â Data library yang digunakan adalah JFS-3-J33 70 grup energi neutron yang merupakan data dari kode komputer SLAROM dari JAEA Jepang.Â Rentang energi dibagi ke dalam tiga daerah grup energi yaitu grup energi cepat, grup energi menengah dan grup energi termal.Â Metode iterasi yang digunakan dalam penelitian ini adalah metode iterasi Gauss-Seidel.Â Hasil penelitian menunjukkan bahwa distribusi fluks neutron pada grup energi cepat untuk bahan bakar U-235 dan Pu-239 berkisar antara 32,96 n/s cm2Â sampai 121,95Â n/s cm2, sedangkan pada grup energi menengah terjadi tumpang tindih antar grup energi dan pada grup energi termal distribusi fluks neutron untuk U-238 lebih rendah dibandingkan dengan U-235 dan Pu-239. Perbedaan nilai ini terjadi karena U-238 merupakan bahan fertil. Distribusi fluks neutron pada grup energi cepat memiliki nilai lebih akurat dibandingkan dengan grup energi menengah dan termalkarena penelitian ini didesain untuk reaktor cepat.Â Research on the distribution of the neutron flux in the one-dimensional multigroup neutron diffusion equation has been done. The type of reactor used is a fast reactor with a slab-shaped reactor core, and the fuel used is U-PuN. The study used macroscopic cross-sections at the fuel cell level as initial input for 70 neutron energy groups. The data library used is JFS-3-J33 70 energy groups, the library data of SLAROM computer codes from JAEA Japan. The energy range is divided into three regions of neutron energy groups, namely fast, medium, and thermal energy groups. The iteration method used in this study is the Gauss-Seidel iteration method. The results showed that the flux distribution in the fast energy group for U-235 and Pu-239 fuels ranged from 32.96 n/s cm2 to 121.95 n/s cm2, whereas in the intermediate neutron energy group overlaps each other and in the thermal energy group the U-238 neutron flux distribution is lower than U-235 and Pu-239. This difference in value occurs because U-238 is fertile material. The distribution of neutron flux in the fast energy group has a more accurate value compared to the medium and thermal energy groups because this study is designed for fast reactors.

Telah dilakukan penelitian tentang struktur dan karakteristik termal sinter silika pada mata air panas Panti, Kabupaten Pasaman. Karakterisasi termalÂ menggunakan metode Differential Thermal Analysis (DTA) dengan suhu pemanasan maksimal 1100Â°C untuk melihat perubahan fasa kristalin dari sinter silika. Berdasarkan hasil uji DTA, suhu terjadinya proses endoterm hampir sama pada kedua sampel yaitu titik A pada suhu 91,9Â°C dan titik B 91,8Â°C. Silika pada titik A mengalami transisi Î± â†’ Î²-quartz pada suhu 710,8Â°C selanjutnya perubahan Î²-quartz â†’ Î²-tridymite pada suhu 848,8Â°C. Sampel silika pada titik B mengalami transisi fasa pada suhu yang lebih rendah dibanding titik A yaitu perubahanÂ Î± â†’ Î²-quartz pada suhu 523,7Â°C dan Î²-quartz â†’ Î²-tridymite pada suhu 711,2Â°C. Titik A membutuhkan suhu yang lebih tinggi untuk berubah dari Î²-quartz â†’ Î²-tridymite dibandingkan pada titik B. Ini mengindikasikan bahwa sampel pada titik B memiliki kandungan silika yang lebih tinggi dibandingkan titik A. Struktur sinter silika diuji menggunakan X-Ray Diffractometer (XRD). Hasil uji XRD menunjukkan bahwa sinter silika pada kedua titik memiliki fase opal-CT. Hal ini mengindikasikan bahwa sinter silika pada mata air panas panti, Pasaman memiliki usia >10.000 tahun dan aktifitas termal panas bumi daerah penelitian ini sudah ada puluhan ribu tahun.Â Structure and thermal characteristics of silica sinter on hot spring in Panti, Pasaman District has been investigated. The thermal characteristics used the Differential Thermal Analysis (DTA) method with a maximum heat temperatureÂ of 1100Â°C to see the crystalline phase changes from silica sinter. Based on DTA test, the temperature of the endothermic process is almost the same in both samples, are 91,9Â°C at point A and 91,8Â°C at point B. The change Î± â†’ Î²-quartz at point A occurs at 710,8Â°C and Î²-quartz â†’ Î²-tridymite occurs at 848,8Â°C. Silica sinter at point B have transitioned at temperatures lower than point A, the changeÂ Î± â†’ Î²-quartz occurs at 523,7Â°C and Î²-quartz â†’ Î²-tridymite at 711,2Â°C. Siica at point A requires a higher temperature to change from Î²-quartz â†’ Î²-tridymite than that at point B, this indicates that the sample at point B has a higher silica content than point A. The silica sinter structure was tested using an X-Ray Diffractometer (XRD). The XRD results showed that the phase of silica sinters at both points is opal-CT. It indicates that silica sinters at the hotspring in Panti, Pasaman has an age >10,000 years and the geothermal thermal activity of this research area has existed for tens of thousands of years.

Authors: Kayano Shingo , Ito Akira , Endo Toshiki , Nemoto Hitoshi , Shimada Kazuki , Niizuma Kuniyasu , Tominaga Teiji 
Published: March 2022

Background:
Following clipping surgery for intracranial aneurysm, computed tomography angiography (CTA) is often used to confirm complete aneurysm obliteration. However, artifacts from the titanium clips usually degrade the images around them. The ultra-high-resolution computed tomography (UHR-CT) system recently became available in clinical practice. Here, we report a case in which CTA using the UHR-CT system successfully pointed out a small aneurysmal remnant after the clipping surgery, which was validated by digital subtraction angiography.

Case Description:
A patient underwent clipping surgery for an unruptured aneurysm using two titanium alloy clips. CTA using the UHR-CT system demonstrated a small remnant aneurysm. Digital subtraction angiography confirmed the minor remnant. The UHR-CTA images were comparable to three-dimensional reconstructed images from the rotational angiography.

Conclusion:
We propose that UHR-CTA is a reliable postoperative assessment method for intracranial clipping surgeries.
Dissecting aneurysm of the anterior inferior cerebellar artery in the internal auditory canal presenting with deafness without hemorrhage: A case report and literature review
Authors: Okada Tomohisa , Makimoto Kaisei , Yoshii Riichiro , Yoshimoto Koji , Moinuddin F. M. , Yamashita Masaru , Arita Kazunori 
Published: March 2022

Background:
Anterior inferior cerebellar artery (AICA) aneurysms in the internal auditory canal (IAC) are rare. We have reported a case of dissecting AICA aneurysm in the IAC presenting initially with the eighth nerve palsy followed by the seventh nerve palsy without hemorrhage.

Case Description:
A 68-year-old woman presented with a sudden onset of vertigo accompanied by deafness and tinnitus on the right side that was preceded by intermittent right retroauricular pain 2 weeks before. Audiogram showed severe sensorineural hearing loss. Computed tomography and magnetic resonance imaging (MRI) indicated absence of prior subarachnoid hemorrhage. Magnetic resonance angiogram (MRA) suggested a tiny aneurysm at the fundus of the IAC accompanied with thinning of the lateral pontine segment of the AICA. Conservative treatment led to moderate improvement of the symptoms. However, the patient developed the right retroauricular pain again, followed by the right facial paralysis 5 months later but still without signs of hemorrhage on MRI. Digital subtraction angiogram showed dissecting aneurysm in the IAC. The patient was managed with oral steroids and direct intervention was avoided due to a risk of ischemia supposed by large area irrigated by the AICA. Follow-up MRA 18 months after the first presentation showed improvement in the narrowing of the AICA proximal to the aneurysm. The patient was functionally independent despite right-sided hearing loss and slight facial paresis.

Conclusion:
This report warns physicians that a dissecting AICA aneurysm without subarachnoid hemorrhage may cause eighth and seventh nerve palsy.
Hematoma expansion caused by trapped cerebrospinal fluid in subacute phase intracerebral hemorrhage: A case report
Authors: Yamaguchi Susumu , Yoshida Michiharu , Iwanaga Mitsuto 
Published: March 2022

Background:
Although hematoma expansion (HE) is caused by active bleeding in patients with intracranial hemorrhage in most cases, cerebrospinal fluid (CSF) trapped in the hematoma cavity is not a well-known cause of HE.

Case Description:
We present a case of subcortical hemorrhage in an 80-year-old woman who experienced neurological deterioration in the subacute phase because of HE caused by CSF pooling in the hematoma cavity. The patient was transferred to our hospital from a previous hospital for surgical treatment because the consciousness disturbance was likely caused by the perihematomal edema that occurred 4 days after onset. Head computed tomography (CT) at admission to our hospital showed a blend sign, and a part of the low-density area of the hematoma was enlarged compared with the CT at admission to the previous hospital. Although the hematoma was located adjacent to the lateral ventricle, no intraventricular hemorrhage was observed. Emergent hematoma evacuation was performed, and intraoperative findings indicated that the enlarged hematoma cavity was caused by CSF pooling. The patient’s postoperative course was uneventful. She was transferred to a rehabilitation hospital 16 days after admission to our hospital.

Conclusion:
Hematomas adjacent to the ventricle and showing a blend sign can expand in the subacute phase because of the trapped CSF.
THE STATE OF ECOLOGY MENTALITY AND PROSPECTS FOR GLOBAL SOCIO-ECONOMIC DEVELOPMENT
Authors: Шорохов Юрий Иванович 
Published: March 2022

Развитие человечества рассматривается как неосознаваемый процесс поэтапного формирования глобального, интегрированного с планетой Земля социального организма. Сформулированы общие требования к менталитету разработчиков и исполнителей программ развития, соблюдение которых позволяет развиваться в соответствии с ключевым направлением эволюции. Показано, что сохранение в менталитете руководителей бизнеса представлений о будущем и способах его достижения, сложившихся в условиях современной экономики, делает невозможным завершение процесса интеграции с планетой Земля, с неизбежностью ведёт к глобальной социальной или (и) экологической катастрофе и, возможно, возвращению на доисторический этап развития.
The development of mankind is considered as an unconscious process of gradual formation of a global, integrated with the planet Earth, social organism. The general requirements for the mentality of developers and executors of development programs have been formulated, compliance with which allows developing in accordance with the key direction of evolution of the planet «Earth». It is shown that the preservation in the mentality of the leaders of business of ideas about the future and ways to achieve it, which have developed in the conditions of the modern economy, makes it impossible to complete the process of integration with the planet Earth, inevitably leads to a global social or (and) environmental catastrophe and, possibly, a return to the prehistoric stage of development.

Nilai kohesi dan sudut geser dalam tanah merupakan parameter kekuatan geser tanah (soil shear strength), yang sering digunakan di dalam perancangan bangunan yang berkaitan dengan bidang geoteknik. Nilai kohesi dan sudut geser dalam tanah tersebut diperoleh melalui tes triaksial, yang memerlukan biaya peralatan, metoda, waktu yang besar. Di samping itu, akurasi data yang diperoleh akibat metoda pengambilan contoh tanah, sangat bergantung pada tingkat ketergangguan contoh tanah yang akan ditinjau.
Oleh karena itu perlu ditelusuri hubungan antara nilai kohesi dan sudut geser dalam tanah dengan parameter kekuatan tanah yang dapat diperoleh melalui tes lapangan yang lebih sederhana serta tidak dipengaruhi oleh ketergangguan tanah akibat cara pengambilan contoh. Salah satu metoda praktis untuk mengetahui kekuatan tanah di lapangan (in situjadalah melalui Standard Penetration Test (SPT ). Dengan mengabaikan pengaruh riwayat pembebanan tanah, maka penelitian ini dilaksanakan untuk menelusuri hubungan antara sudut geser dalam tanah dan kohesi terhadap nilai N-SPT. Hasil studi penelitian terhadap tanah lempung jenis CH, dan OH, MH yang diambil dari Cibeber, Cimahi, Jawa Barat, menunjukkan adanya korelasi positif antara nilai kohesi dan sudut geser dalam tanah terhadap N-SPT.
