Dissolution, Mechanical Properties, and Thermal Stability of Microparticles Containing Radioactive Cesium on Plant Litter Derived from the Fukushima Daiichi Nuclear Power Plant Accident
Authors: Tanaka Ichiro , Yamaguchi Atsushi , Kikuchi Kenji , Komatsuzaki Masakazu , Tanaka Ichiro , NIIMURA Nobuo
Published: December 2020

Most of the radioactive cesium (134Cs and 137Cs), which originated from the Fukushima Daiichi Nuclear
Power Plant (FDNPP) accident, has remained in the soil and on plants as water-insoluble microparticles
(termed as CsMPs) and maintained relatively high radioactivity levels in the district. However, it has been
reported that the radioactive Cs has been absorbed by plants. To interpret this phenomenon, the authors
investigated CsMPs to determine if they become soluble during filtration and dialysis experiments.
Moreover, other physical properties, such as mechanical properties and thermal stability, were observed
during the course of the relevant experiments. These properties can be obtained by using carbonized
charcoal litter with CsMPs.

This paper presents an anonymous and unknown poem from the manuscript written by a PolishArian, Andrzej Lubieniecki (Remonstrants’ Library in Rotterdam, MS 527). It is the first truly comprehensive poetic description of the Netherlands. The composition of the poem is ruled by rhetoric– the laudatory topic of a place and a person. The anonymous author’s opinion is confronted withthat expressed by Jakub Kazimierz Haur in his poem O holenderskich krainach z narodem (partof Haur’s Mercurius… MS 191 Library of the University of Warsaw MS 191). The anonymousdescription is written from the Arian point of view; its author admires the spirit of liberty and thedynamism observed in Holland.
Postmemory of the Holocaust in modern research
Authors: Wierzbicka Justyna
Published: December 2020

This paper describes the Holocaust in modern research. The principal works in the contextof heritage trauma were penned by Barbara Engelking (Holocaust and Memory: The Experience of the Holocaust and Its Consequences: An Investigation Based on Personal Narratives) and Marianne Hirsh (Żałoba i postpamięć [Mourning and Postmemory]). Their analyses show how different were the attitudes taken by people who survived the Holocaust. I have completed my work with other research, focusing on the literature discussing psychological and political aspects. The aim was to show the diversity of the effects produced by the Holocaust and its unfading resonance in various areas of life.
Le sujet et le handicap : accompagnement neuropsychologique et psychologique à long terme d’enfants atteints de cancer
Authors: Rivollet S. , Longaud-Valès A. , Fasse L. , Valteau-Couanet D. , Dauchy S.
Published: December 2020

Les échanges cliniques entre psychologue et neuropsychologue exerçant en oncologie pédiatrique singularisent les patients confrontés au handicap pendant et après les traitements oncologiques mais aussi lorsqu’ils sont en surveillance ou guéris. Aucun enfant n’évolue de la même façon, aussi, ces interactions professionnelles permettent de lutter contre le risque d’immobilisme ou de sidération lié au handicap. Les évaluations neuropsychologiques sont indispensables pour suivre les évolutions et déficits des patients, et mettre en place un projet de soins. Aucun professionnel ne peut prédire ce qui se traduira par un handicap pour son patient, dépendant aussi de la capacité d’adaptation et d’intégration de chaque patient. Il faut alors composer avec l’inconnu, là où patients, parents ou collègues sollicitent les cliniciens pour combler l’incertitude si anxiogène.
Islamic Biopolitics during Pandemics in Russia
Authors: Ragozina Sofya A.
Published: December 2020

In this article I discuss how the pandemic state of emergency has formed a subject field in Islamic biopolitics. By analysing the fatwas and official statements issued by Russian Muslim leaders between March and May 2020, I identify their discursive strategy of ‘interpreting’ the language of bureaucracy and medical terminology into the language of Islam, and of providing theological justification for certain governmental decisions. I consider several cases which illustrate the intervention of political and medical discourses of corporality into religious discourse. These include the politicisation of the regulatory functioning of the body, the sacralisation of quarantine as a special time for spiritual activities, the formatting of funerary ritual according to medico-administrative regulations and the comparing of victory in the Great Patriotic War to the victory over COVID-19.
Norms for beneficial A.I.: A computational analysis of the societal value alignment problem
Authors: Fernandes Pedro M. , Santos Francisco C. , Lopes Manuel
Published: December 2020

The rise of artificial intelligence (A.I.) based systems is already offering substantial benefits to the society as a whole. However, these systems may also enclose potential conflicts and unintended consequences. Notably, people will tend to adopt an A.I. system if it confers them an advantage, at which point non-adopters might push for a strong regulation if that advantage for adopters is at a cost for them. Here we propose an agent-based game-theoretical model for these conflicts, where agents may decide to resort to A.I. to use and acquire additional information on the payoffs of a stochastic game, striving to bring insights from simulation to what has been, hitherto, a mostly philosophical discussion. We frame our results under the current discussion on ethical A.I. and the conflict between individual and societal gains: the societal value alignment problem. We test the arising equilibria in the adoption of A.I. technology under different norms followed by artificial agents, their ensuing benefits, and the emergent levels of wealth inequality. We show that without any regulation, purely selfish A.I. systems will have the strongest advantage, even when a utilitarian A.I. provides significant benefits for the individual and the society. Nevertheless, we show that it is possible to develop A.I. systems following human conscious policies that, when introduced in society, lead to an equilibrium where the gains for the adopters are not at a cost for non-adopters, thus increasing the overall wealth of the population and lowering inequality. However, as shown, a self-organised adoption of such policies would require external regulation.
Assessment of disability levels in patients with low back pain based on the type of lumbar spinal disorder
Authors: Mirzamohammadi Elham , Ghandhari Hasan , Pirbornatan Masoumeh , Mohammadi Saber , Hosseininejad Mahin
Published: December 2020

BACKGROUND: Low back pain (LBP) is a common health condition and the leading cause of activity limitation and absenteeism in most parts of the world. One-fifth of patients with LBP develop chronic pain disability. OBJECTIVE: This study investigated the disability levels in patients with different types of lumbar spinal disorders. METHODS: A total of 528 patients visiting spine clinics between June 2017 and February 2018 were enrolled in this study. A demographic checklist, the patients’ medical records, the Oswestry Disability Questionnaire, and the Visual Analog Scale (VAS) were used to collect the data. RESULTS: Non-specific LBP (29.5%) and discopathy (27%) were the most common final diagnoses. The obtained Oswestry Disability Index (ODI) was significantly higher in older patients, those with higher body mass index, more work experience, and smokers. Lower ODI was found in individuals with a history of regular exercise. Most individuals in all diagnostic groups were categorized into the high ODI group (p⩽ 0.001). CONCLUSION: In patients with lumbar spine lesions, ODI is significantly correlated with age, BMI, work experience, smoking, and the type of disorder (discopathy, spondylolysis, and spondylolisthesis). Regular exercise is associated with lower levels of disability.
A polyomino puzzle for arithmetic practice
Authors: Foxcroft Jeremy , Ashlock Daniel
Published: December 2020

Recent trends in mathematics education emphasize discovery learning over drill. This has proven to be a bad idea in some cases, for the simple reason that practice is required to learn basic arithmetic skills. Drills in arithmetic skills can be made interesting through gamification. This study proposes a family of puzzles that gamify arithmetic practice. The puzzles are designed with an evolutionary algorithm forming an instance of automatic content generation. Two methods of evolutionary puzzle design are presented and discussed. The first method used transformed the problem into an almost trivial optimization. The second algorithm was designed to avoid the flaws of the first and produced a huge variety of puzzles. A hardness measure, based on the difficulty experienced by the evolutionary puzzle generator, is employed. The hardness measure is tested on a large collection of puzzles produced with the evolutionary automatic content generation system. An initial assumption, that all the pieces in the puzzle must be used to achieve a maximum score, was shown to be incorrect in puzzles located via automatic search. Two classes of puzzle are defined: those where the optimal solution uses all pieces and those where the optimal solution fails to use at least one piece. The latter sort of puzzle were found to be far more common in the search space.

Hydrological Modeling with HEC-HMS in the Karangmumus Sub-watershed Samarinda. The HEC-HMS is used to develop a model of water flow in the Karangmumus which can be used as an alternative for flooding problem. The purpose of this study is to determine the amount of flow discharge generated from rainfall that enters the Karangmumus using the HEC-HMS and to determine the effect of rain parameters on the HEC-HMS to make an hydrological model simulation.For simulation using daily rainfall and water level data, curve number, percentage of watertight, amount of initial absorption and the time needed to reach the peak discharge in the sub-watersheds obtained from the river model created. The highest rainfall Karangmumus Sub-watershed that is 84,4 mm produces a discharge of 211 m3/sec and at the lowest rainfall of 1,05 mm produces a discharge of 3,4 m3/sec. Hydrological modeling of the simulation results has the same hydrograph with the rainfall data but not the discharge data calculated with the rating curve. The validation of observing the debit data of the efficiency value (NSE) <0,36 which means that the data used are not satisfactory or invalid.

This study aims to obtain information on plans and spatial use patterns and spatial structures in Muara Siran and Liang Buaya villages and compile information on land cover and socio-economic conditions of the community. Muara Siran Village Spatial Plan and Liang Buaya Village Spatial Plan are divided into 2 areas, namely the Cultivation Zone and the Protected Area. The preparation of the RTRW of Muara Siran Village and Liang Buaya Village is the first example for the Regency Government in the preparation of a participatory Village RTRW in the Kutai Kartanegara District environment. The people of Muara Siran Village and Liang Buaya Village are dominated by the Kutai tribe, most of whose livelihoods are fishing, farming and cage cultivation. So that village spatial planning becomes very important in the utilization and control of natural resources. With the implementation of the participatory village spatial planning concept, it needs to be replicated by other villages in Kutai Kartanegara Regency to support development as well as to protect the area through spatial planning so that in future development planning is in accordance with the potential of each village.

Published: December 2020

PT Kelian Equatorial Mining (KEM) applied the open pit mining practice in its production phase in the past. The barred land was formed not only by the excavation and digging processes, but also formed by the dumping of the waste rocks. These processes were assumed as the factor the biodiversity decline or loss. The performance of completed and ongoing reclamation efforts, which refer to the most current regulation and law, is solely defined through the quantitative assessment on the survival of the planted tress on the reclamation site, on the other hand, despite very important, no such assessment is undertaken to examine the ecological recovery of the biodiversity on that site. Hence, this research aims at (1) identifying the presence of amphibians from the order of anura (frog and toad) in the reclamation sites of post open pit mining area, (2) identifying the dynamic of the presence of such amphibians during a 5 year time series. The research identified 13 species of amphibians, which categorized into 6 families. Most of the observed location are still dominated by the common species, which could be encountered in very common open area habitat.
