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.

Published: March 2022

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.
Efficacy of ultra-high-resolution computed tomographic angiography for postoperative evaluation of intracranial aneurysm after clipping surgery: A case report
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.
Transfert réciproque d'oxygéne et d'hydrogéne entre deux ligands coordonnés à une ossature dinucléaire de ruthénium: synthèse et structure moléculaire de Ru₂(CO)₆(μ-PCy₂)[μ-P(O)Cy₂]

Published: March 2022

The dinuclear propionato complexes (Ru2(CO)4(μ-O2CEt)2(PR2H)2 (R = Ph: 1,R = Cy: 2) react under carbon monoxide pressure to give the phosphido complexes Ru2(CO)6(μ-PR2)2 (R = Ph: 3, R = Cy: 4) as well as the phosphido-phosphinito complexes Ru2(CO)6(μ-PR2)[μ-P(O)R2] (R = Ph: 5, R = Cy: 6). The simultaneous formation of propionic acid and propionic aldehyde suggests that a H-atom is transferred from the phosphine to the propionato ligand, while an O-atom is transferred from the propionato to the phosphine ligand. The single-crystal X-ray structure analysis of 6 reveals this dinuclear complex to have a 'sawhorse' type structure in which the Ru2 backbone is bridged by a μ2-phosphido and a μ2-phosphinito ligand.

Published: March 2022

The symmetrical ligand 2,5-bis(2'-pyridyl)pyrazine (BPPZ) exists in the extended form with a dihedral angle between the pyrazine and the pyridine rings of 7.88°. BPPZ forms symmetrical bis(bidenate) complexes with MnII, FeII, and CuII. The dihedral angles between the best planes through the planar pyrazine ring and the pyridine ring are 2.6° in the MnII complex, 4° in the FeII complex, and 8.5° in the CuII complex. The metal-Npy bond distances are shorter than standard values and similar in length to the metal-Npz distances.

The combination of adsorption and calorimetric techniques shows that the adsorption of CO2 is a two-step process in the case of active carbons with large micropores (L > 1.2–1.5 nm). For smaller pores, on the other hand, one observes a uniform filling of the volume. These mechanisms are in agreement with earlier experiments carried out with CH2Cl2 at 293 K.

Published: March 2022

The membrane deposition technology on silicon-based transducers constitutes the most delicate part of the miniaturized (bio)chemical sensor fabrication. Membrane adhesion to the transducer, reproducibility of the deposition process and its spatial control are the three most important parameters which determine the sensor performance and lifetime.The fabrication of two sensors is described: 1) a combined pO2, pCO2, pH sensor for which a polyacrylamide gel and a polysiloxane gas-permeable membrane were deposited and patterned at the on-wafer level and 2) a glucose amperometric enzyme electrode where the glucose oxidase was immobilized electrochemically either in a polypyrrole matrix or co-deposited with bovine serum albumin by electrochemically aided adsorption. The optimization of the deposition procedures allowed reproducible devices with reasonable lifetimes to be obtained.

Authors: Prakash Gnana
Published: March 2022

The most sensitive and complex organ in the human body is the eye, so special attention should be needed for the administration of pharmaceutical substances into the eye. It is one of the most difficult for researchers in the preparation of drug delivery to the eye. The anatomical characteristics and physiological properties of the eye should be considered in drug delivery. The properties of pharmaceutical dosage forms depend upon the anatomy and physiology of the eye. Drug delivery on to the outer part as well as in the inner part of the ocular structure for the therapy is a unique and challenging one. Physiochemical, microbiological, and pharmaceutical properties lead to absorption and elimination of active therapeutic agents into and out of the eye. Loss of precorneal more and fastly occurs due to drainage in the region of extraocular are some of the drawbacks in ocular drug delivery of conventional dosage forms. To overcome these problems, advancements in conventional dosage forms take place.
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.

Authors: Couto Cremilda Barreto
Published: March 2022

Este artigo parte da compreensão do campo da política pública, considerando-o como espaço de disputas. Ao pensar a formação continuada como uma política pública apresenta-se o Ciclo de Políticas (SECCHI, 2012; 2016), como referencial de análise, para discussão de possibilidades. Utiliza-se como instrumento de pesquisa a observação em quatro escolas públicas, em turmas de quinto anos, no município de Macaé/RJ e aplicação de questionários semiestruturados junto aos professores. A elaboração de uma questão discursiva serviu como objeto de análise para o estudo aqui apresentado. A partir da identificação dos problemas relativos à formação continuada realizou-se reflexão acerca de soluções e alternativas, apresentadas em uma matriz de avaliação. O modelo de formação tido como recomendação de solução ao problema diagnosticado passa por algumas etapas. Acredita-se que a aplicação dessa metodologia de análise pode vir a ser um gerador de política de formação continuada, possibilitando maior interação dos professores em sua formação.

Authors: Murakami Marlene Aparecida Morceli
Published: March 2022

Este artigo, realizado por meio de estudo bibliográfico, pretende abordar a respeito dos desafios do uso de tecnologias na sala de aula para a educação no século XXI. A cultura analógica na escola com práticas tradicionais seculares é conflitante com a cultura digital provocando dissonâncias entre o mundo dos estudantes e o mundo da escola.

Increasing time has made technological advances increase, including in the field of fisheries which has a positive impact on fishing business in Indonesia. Environmentally friendly fishing technology is a fishing gear that does not have a negative impact on the environment. The use of environmentally friendly fishing gear is very important to be applied in the fishing process in certain waters. This study was conducted in Kranji Village, Paciran District, Lamongan Regency. The purpose of this study is to analyse the level of friendliness of fishing gear in Kranji Village, besides the specifications, operating methods, and variety of catches. The  research  method  used  survey  and  in-depth interviews with related parties related to the results of research and the level of friendliness of  fishing gear. The weighting determination of the level of environmental friendliness of fishing gear is based on the Food and Agriculture Organization (FAO). The results of this study shows that the purse seine fishing gear, cob nets, gill nets and payang are environmentally friendly fishing gears, while mini trawlers are non-environmentally friendly fishing gear. This indicates that the presence of trawling gear can affect the decline in fishery resources in Kranji, Lamongan Regency.

Stingray is a type of fish included in the Elasmobranchii class that has high economic potential. This study aims to determine the sex ratio, growth rate, length-weight relationship, condition factor, mortality and exploitation rate of stingray (Neotrygon orientalis) in PPN Brondong, Lamongan. Samples N. orientalis collected every week starting from October 1, 2019 until January 2021 and weighed in total body weight (gram) and measured in total body length (cm) then sex was identified based on macroscopic characteristics of gonads. The results showed that the sex ratio of N. orientalis was 1.4 : 1. Length growth value (K) of male and female N. orientalis are 0.0285 and 0.0233, respectively, which show a slow growth time to reach the asymptotic length (K≤ 0.5). Based on the analysis of the relationship between length and weight, the results show that b value are 1.9394 and 2.2023 in male and female N. orientalis, respectively, which means length growth rate faster than weight growth (b< 3, negative allometric). N. orientalis are included in the category of flat (thin) fish with condition factor values ranging from 0.2462-3.9227. The total, natural, and fishing mortality rate were 0.395, 0.177, and 0.218, respectively. The exploitation rate is 0.551 where the value has exceeded the optimum value 0.5, which means that N. orientalis landed at the PPN Brondong, Lamongan has indicated overfishing caused by excessive fishing activity.

Priestia megaterium BIM В‑1314D is a halotolerant strain able to adapt to osmotic stress. The analysis of a full nucleotide sequence of bacterium P. megaterium BIM В‑1314D has revealed that the genome of the studied strain is represented by one circular chromosome and nine plasmids, deposited in the database of GenBank NCBI under the registration number CP058262–CP058271. The size of the bacterial genome constitutes 5 984 922 base pairs with an average GC content of 37.7 %. The genome contains 6 187 genes where 5 978 were annotated as protein-enconding, 92 – as pseudogenes, 154 – as tRNA genes, 8 – as ncRNA, 47 – as rRNA. The genes responsible for synthesis and transport of betaine and proline osmolytes and transport of potassium ions ensuring the adaptation of strain P. megaterium BIM В‑1314D to osmotic stress were local-ized in the genome. Gene loci were defined encoding production of metabolites involved in the synthesis of phytohormones and polyamines accounting for the growth-promoting microbial ability. Gene clusters determining the synthesis of secondary metabolites, cold and heat shock proteins were revealed in the genome. The genome analysis of strain P. megaterium BIM В‑1314D provides the valuable data on the bacterial culture for stimulation of the plant growth in the salinized conditions.

Published: March 2022

An approach has been developed to construct functional expressions for calculating the effective mechanical characteristics of the undermined rock massif during its repeated mining, taking into account the disturbance of the different-type massif continuity and the time passed after the undermining. The approach was developed as applied to the conditions of the Starobin potash salt deposit. It is based on introducing special correction factors into the expressions for mechanical characteristics of the massif. At the same time, the state of the undermined massif area is considered in the continuum model approximation. It is shown that one of the most important factors to be considered when constructing the functional dependence for mechanical characteristics of the undermined layered massif is to take into account the mutual slippage of layers and their lamination related to it, because the strength characteristics such as bonding strength and internal friction coefficient mainly change when the massif is undermined. The algorithm for calculating the mechanical properties of the undermined massif proposes the use of correction factors that take into account the heterogeneity of the rock massif; lamination and slippage of the contacting layers; changes in the properties of the undermined massif with variation of the depth of repeated mining; changes in the properties resulting from the technological disturbance of the massif initial equilibrium state (primary undermining, time passed since the primary undermining).
Spatial features of the risk of oncological diseases in the territory of the Gomel and Mogilev regions of Belarus

The article presents the results of the cartographic analysis of the Belarusian Cancer Registry data, including the spatial features of morbidity due to cancer in different sex and age groups of the rural population. The maps, characterizing the features of the spatial heterogeneity of the oncological diseases (OD) in the Gomel and Mogilev regions of Belarus, were built for the first time. The performed mapping revealed the anomalous zones, representing the groups of compactly located rural settlements, for which the OD level (including OD of different localizations observed in both men and women) differs by a factor of 4 or more. The assessed differences in the OD risk are statistically significant. On this basis, we infer that the anomalous zones in the territory of Belarus, in any case, demonstrate both a high spatial contrast of OD manifestation and regular spatial organization. These confirm the hypothesis about a relationship between the OD risk and the environmental parameters and, in turn, allow a reasonable conclusion about the endemic nature of cancer as a provoked “human disease”. We consider that the detected zones of positive and negative anomalies must have significant ecological and geochemical differences. Therefore, they should be recognized as the objects of priority control since the population living in the high-risk areas undoubtedly needs priority screening and applying the corresponding preventive measures.

Classical homocystinuria is caused by a genetic mutation in the CBS gene, which leads to low levels or absence of an enzyme called cystathionine beta-synthase.

The purpose of the study was to analyze the clinical features and molecular and genetic data of patients with classical homocystinuria in Belarus.

The study group included patients with classical homocystinuria and their healthy siblings (3 probands and 2 siblings) from three unrelated families. Diagnosis of homocystinuria was made on a quantitative determination of the total homocysteine level in plasma. The next-generation sequencing was performed for the molecular genetic analysis of the CBS gene. The presence of the identified variants in probands and their siblings was confirmed by the Sanger sequencing.

All probands had specific clinical signs of classic homocystinuria: ectopia lentis, skeletal pathology, intellectual, psychiatric, behavioural problems and seizures (in 2 of 3 probands).

Homozygous missense-mutations c.430G>C (p.Glu144Gln, rs121964966), c.473C>T p.(Ala158Val, rs1376851289) and 1064C>T p.(Ala355Val, rs772384826) were identified in proband 1, 2 and 3 respectively. Healthy siblings of probands 1 and 3 were the heterozygous carriers of the corresponding mutations.

Classical homocystinuria is a very rare disease in the Republic of Belarus. All cases of the disease in Belarus are caused by very rare mutations not registered in the neighboring countries and are the result of marriages between the relatives or the natives of the same area. We have described for the first time the phenotypic manifestations of the p.Glu144Gln and p.Ala355Val mutations, expanded the description of the spectrum of clinical manifestations of the Ala158Val substitution, and assessed the clinical significance of the identified variants in accordance with the modern criteria.
