Simulating the carbon distribution in zirconium alloy spent fuel cladding
Authors: Otsuka Teppei , Kondo Yuya , Ogawa Hiroyuki , Sakuragi Tomofumi 
Published: February 2023

AbstractThe diffusivity values of C in pure Zr and in Zr containing dissolved O (Zr(O)) were determined in a temperature range of 623–1023 K for Zr and 923–1123 K for Zr(O) from depth profiles of C obtained by glow-discharge emission spectroscopy. The C diffusivity in Zr(O) decreased as the O concentration in Zr increased and that for Zr containing 15 at % O was two orders of magnitude smaller than that for pure Zr. One-dimensional numerical calculations of Fick’s diffusion equation with a Soret effect indicated various non-uniform distributions of C in a 5-mm-thick Zr matrix under a temperature gradient of 573 to 773 K for 3 years, assuming a heat of transport of − 1.5 to + 1.5 eV. Isothermal annealing at 773 K for 10 years could result in a uniform distribution, whereas dissolution of O in the interstitials of the Zr matrix would hinder C transport through the interstitials.
Graphical Abstract

As concentration of O increased in HIP Zr by 15 at%, the diffusivity of C decreased more than two orders of magnitude.

Posterior a la entrada en vigencia de la Constitución Política de Colombia de 1991, nace como pilar fundamental en lo que respecta a la protección del medio ambiente, una preocupación del legislador por establecer una eficiente vigilancia de la gestión fiscal del Estado, coadyuvada por algunos organismos que tienen como función principal, la de realizar un seguimiento permanente al recurso Público, sin oponibilidad de reserva legal para el acceso de la información, cimentado en la eficiencia, economía, equidad, desarrollo sostenible y el verificado cumplimiento del principio de valoración de costos ambientales.
Pese a que existe en Colombia, una gran cantidad de normas que tienen como fin último, el de proteger el bien jurídico más preciado, el medio ambiente, se destacará mediante lo observado en la presente investigación, con datos extraídos de los sistemas de rendición de cuenta de la Auditoría General de la República - AGR (SIA MISIONAL 2018-2021) , de informes tanto de la Contraloría General de la República (CGR 2018-2020) como de las Contralorías Territoriales , que el control fiscal ambiental no ha sido aplicado eficientemente, respecto de los distintos tipos de recursos naturales. Esto es, agua, aire, biodiversidad, o el suelo. Por lo tanto, se incrementa con ello, la problemática ambiental del país.

Authors: Chandra Savita , Ansari Arshi 
Published: February 2023

Background: This was a prospective case control study conducted in the department of obstetrics and gynecology, Era’s Lucknow Medical College and Hospital from November 2018 to March 2020. Aim was to find whether there was a link between serum 25-OH vitamin D levels, and insulin resistance in women with polycystic ovarian syndrome (PCOS).
Methods: 30 newly diagnosed cases of PCOS and 30 women without PCOS were enrolled. Their clinical details as well as BMI and waist hip ratio were noted. The biochemical parameters which were measured included fasting glucose, fasting insulin, serum 25-OH vitamin D. The insulin resistance was calculated.
Results: 50% of the PCOS had insulin resistance and also deficient /or insufficient vitamin D levels, versus 16.7% in the control group. This association was statistically highly significant with p value as 0.00016. No statistical significance was found with regard to the mean serum 25-OH vitamin D level. 53.4%, of the PCOS women had hirsutism versus 3.3% in the control group and was statistically significant, p value <0.0001. 20% of PCOS women had acne in contrast to 3.3% in the control group which was statistically significant with p value 0.0443.
Conclusions: Hirsutism and acne were important clinical signs of PCOS. There was a negative correlation between insulin resistance and serum 25-OH vitamin D levels. Thus, vitamin D may be an important link in the genesis of PCOS. Larger randomised case control studies need to be done to understand PCOS.

A Detailed Model of Magnetic Field Sources of the Earth’s Core Obtained by Solving the Inverse Problem of Magnetometry
Authors: Kochnev V.A. 
Published: February 2023

Abstract
—Magnetic field sources are sometimes approximated by magnetic dipoles or current loops. The usefulness of such approximations is not obvious at the initial stage of the study of objects. Investigating them in detail requires volumetric magnetic field sources. In this paper, they are represented by magnetized prisms. Such a model is valid due to the equivalence of current and magnetized objects. As there should be no real magnetization in the core, this property of a virtual prism to generate a magnetic field strength is referred to as virtual or effective magnetization (EM), which is determined for each prism by solving the inverse problem via the adaptive method. Initial data for solving the inverse problem are the Z vector components of the main magnetic field of the IGRF-2005 model in the geocentric coordinate system. Based on the effective magnetization and known formulas, the bulk current distribution, the bulk current density, and the magnetic moments of prisms of a two-layer core model are obtained. Their sum coincides with the magnetic moment of the virtual central dipole of the core, but, as many scientists assumed, the central dipole is not actually distinguished. At the same time, four significant inhomogeneities are identified in the core, which create the Canadian, Siberian-Asian, Australian, and negative South Atlantic global anomalies on the Earth’s surface. Based on the analysis of the results obtained, assumptions are made that the current generating the magnetic field is the motion of a positively weakly charged liquid of the core. Liquid motion is created by the rotation of the Earth and the decelerating gravitational forces of the Moon and the Sun. Arguments are given to support these assumptions. The results are illustrated in figures.

Published: February 2023

Abstract
Background:Ocular neuropathic pain (ONP) has various etiologies and substantially decreases the quality of life of patients. Theclinical management of patientswith ONP has been debated. Based on the convergence in the trigeminocervical complex, this study evaluated the effect of repeated greater occipital nerve block (GONB) for ONP.
Methods:Two hundred and four patients received a GONB every two weeks, up to 10 times. The posttreatmentoutcomes were measured using a pain relief scale at the next visit, with the first visit as the baseline (10).
Results: The differences and magnitude of decrease in the overall pain relief scale score (estimate=-0.55, p<0.001) were statistically significant. The changes in pain relief scale scores of eye pain (-0.54, p<0.001), dysesthesias/allodynia (-0.52, p<0.001), noneye pain (-0.39, p<0.001), visual disturbance (-0.38, p<0.001) and tearing (-0.52, p<0.001) were also statistically significant between the assessment time points.
Conclusions:Although it is premature to recommend repeated GONB for the management of ONP, it can be used as an effective technique.

Consistent Epistemic Planning for Multiagent Deep Reinforcement Learning
Authors: Wu Peiliang , Luo ShiCheng , Tian LiQiang , Mao BingYi , Chen enbai 
Published: February 2023

Abstract
Multi-agent cooperation needs to reason about beliefs in the partially observable environment without communication, but the traditional Multi-agent Deep Reinforcement Learning (MADRL) algorithm struggles to handle the uncertainty of agents. Multi-agent Epistemic planning (MEP) tries to let the agent find a best plan to complete the cooperation task, so as to more effectively solve the uncertainty. However, inconsistent planning arises if the MADRL only adds MEP. We propose a MADRL-based policy network architecture called SMM-MEPP: Shared Mental Model - Multi-agent Epistemic Planning Policy. Firstly, Multi-agent Epistemic Planning and MADRL are investigated to build the "Perception-Planning-Action" multi-agent epistemic planning framework. Then, mental model in psychology is introduced and descript as a neural network. Thirdly, parameter sharing mechanism is utilized to achieve the shared mental model and maintain the consistency of epistemic planning. Finally, we apply the SMM-MEPP architecture to three advanced MADRL algorithms (i.e., MAAC, MADDPG and MAPPO) and conduct comparative experiments in multi-agent cooperation tasks. Experiments show that the proposed method can bring consistent planning for multiple agents, and improves convergence speed or training effect in partially observable environment without communication.
