Authors: Kumar Lalit , Gora Swapna , Rana Vikram , Khachi Anil , Sastri O. S. K. S. 
Published: October 2021

In this paper, the systematics for obtaining the Viola-Seaborg formula (VSF) for logarithmic partial alpha half-lives (Tα1/2) have been undertaken based on the NUBASE2016 evaluation. The constants Az and Bz in Geiger-Nuttal law for determination of Tα1/2 , are obtained using gs-gs transitions data, of even-even nuclei for two sets of nuclei with Z = 84 - 102 and Z = 86 - 98 with N > 126. The Viola-Seaborg co-efficients are determined for both the sets. The obtained parameters for both sets are tested on even-even nuclei for Z ranging from 104 - 118 and it is observed that first set parameters fare better. This formula for estimating α-decay half-lives of heavy nuclei can be extrapolated to predict those of super-heavy nuclei. The logarithmic half-lives Tα1/2 obtained for isotopes of Z = 121 and 122 using current modified VSF (AME2016) are compared with those obtained from theoretical considerations using Coulomb and proximity potential model (CPPM) and observed to be much larger. They are also much larger than those obtained from the previous coefficients based on AME2003 data.

O QUE SUSTENTA O INSUSTENTÁVEL? REFLEXÕES DE UM DESENVOLVIMENTO APOIADO NA POBREZA E NA DESIGUALDADE
Authors: Oliveira de Morais Barbara , Ferreira Lopes Alexandre 
Published: October 2021

O presente ensaio teve como objetivo refletir acerca das questões que permeiam a busca por um desenvolvimento sustentável e que culminam no aprofundamento da desigualdade e da pobreza. Em um esforço em demonstrar os efeitos da injustiça ambiental e da (in)sustentabilidade uma vez que a exclusão e a pobreza crescem cada vez mais, provocando distanciamentos e o aprofundamento das desigualdades em diferentes dimensões (social, ambiental e econômica) é que este ensaio foi estruturado. A partir dos conceitos encontrados neste ensaio percebeu-se que a questão da desigualdade ambiental é indissociável da desigualdade social e por essa razão a problemática ambiental nos últimos anos se tornou uma discussão necessária, urgente e imprescindível, visto que é preciso reestabelecer o diálogo acerca dos riscos ambientais que os mais pobres estão suscetíveis.

Background: Malaria is a major public health problem in Nigeria with 97% of its population with high morbidity and mortality. Mosquitoes play an important role in the transmission of malaria parasites. This study was conducted to eval­uate the current resistance status of Anopheles gambiae to insecticides.
Methods: Larvae of An. gambiae was collected from three zones; A, B and C differentiated on the basis of variation in agricultural ecosystems between August and November, 2018 in the northeast and northwestern parts of Nigeria. They were carefully reared to adult stage and insecticidal susceptibility tests were conducted.
Results: The mosquitoes tested showed high levels of resistance to all the insecticides used with the exception of mala­thion. Study zone A, recorded 74% mortality after 24h to deltamethrin compared to 81% from zone B and 82% from zone C, respectively. Mosquitoes from zone B exposed to DDT had the highest level of resistance at 37% compared to 40% and 53% from zones A and C, respec­tively. Resistant to bendiocarb was also observed, with zone A having the lowest mortality of 44% com­pared to 48% from zone C and 55% from Zone B, respectively. According to the results of knockdown tests, mosquitoes from Zone A exposed to deltamethrin recorded the lowest knockdown across the study locations while zone B recorded the lowest knockdown for DDT.
Conclusion: The results of the study provide an insight into the current status of An. gambiae to four major insecticides in northern Nigeria as guideline for mosquitocontrol.
Forced labor of Jews in the Szydłowiec ghetto during World War II - The nature of the work performed, its dimension and social aspects
Authors: Bodo Marlena 
Published: October 2021

Purpose of the study: The article contains information on the forced labor performed by Jews for the benefit of Germans during the Second World War. The research area was narrowed down to the area of the Szydłowiec ghetto and its vicinity (the Radom district in the General Government. The text presents the types of work performed by Jews, forms of forcing them to take up forced labor, and their attempts to bypass German restrictions.
Methodology: This article is based on a comparative-historical method, the aim of which is to enable the researcher to identify Jews as a separate social group that was used by the Germans for forced labor. The use of this method is aimed at learning about the historical processes and mechanisms of functioning of selected Nazi restrictions in Poland. In addition, prosopographic and inductive methods as well as a method based on the grounded theory will be used. Moreover, due to the nature of the subject of the work, the research conducted in this field also requires the use of oral history.
Main Findings: Extremely burdensome, in many aspects, compulsion for Jews was the almost slave labor they performed for the benefit of the Germans. Every Jew had to work at least one day a week for the Third Reich. Jews were used for various types of work, including snow removal from roads. Slave labor for the benefit of the Nazis was one of the causes of the increasing poverty of Jews.
Application: The results of the research make a significant contribution to the knowledge of the history of Jews from Szydłowiec. This research not only broadens the knowledge about the history of the functioning of the Jewish community in Szydłowiec during World War II, but also broadens the knowledge about the history of the Holocaust and the mechanisms of crimes. These studies can be used to further analyze the situation of Jews during the German occupation in the territory of the Radom district, or more broadly, in the territory of the General Government.
Novelty/Originality of the study: For the first time in this study, many fragments of Jewish diaries from the Memorial Book of Szydłowiec were used (some of the memoirs were published only in Yiddish). The article is the basis for further research on the history of Jews during World War II in the area of the Radom district.

Efficient Localized Nonlinear Solution Strategies for Unconventional-Reservoir Simulation with Complex Fractures
Authors: Jiang Jiamin 
Published: October 2021

Abstract
It is very challenging to simulate unconventional reservoirs efficiently and accurately. Transient flow can last for a long time and sharp solution (pressure, saturation, compositions) gradients are induced because of the severe permeability contrast between fracture and matrix. Although high-resolution models for well and fracture are required to achieve adequate resolution, they are computationally too demanding for practical field models with many stages of hydraulic fracture. The paper aims to innovate localization strategies that take advantage of locality on timestep and Newton iteration levels. The strategies readily accommodate to complicated flow mechanisms and multiscale fracture networks in unconventional reservoirs.
Large simulation speed-up can be obtained if performing localized computations only for the solution regions that will change. We develop an a-priori method to exploit the locality, based on the diffusive character of the Newton updates of pressure. The method makes adequate estimate of the active computational gridblock for the next iterate. The active gridblock set marks the ones need to be solved, and then the solution to local linear system is accordingly computed.
Fully Implicit Scheme is used for time discretization. We study several challenging multi-phase and compositional model cases with explicit fractures. The test results demonstrate that significant solution locality of variables exist on timestep and iteration levels. A nonlinear solution update usually has sparsity, and the nonlinear convergence is restricted by a limited fraction of the simulation model. Through aggressive localization, the proposed methods can prevent overly conservative estimate, and thus achieve significant computational speedup. In comparison to a standard Newton method, the novel solver techniques achieve greatly improved solving efficiency. Furthermore, the Newton convergence exhibits no degradation, and there is no impact on the solution accuracy.
Previous works in the literature largely relate to the meshing aspect that accommodates to horizontal wells and hydraulic fractures. We instead develop new nonlinear strategies to perform localization. In particular, the adaptive DD method produces proper domain partitions according to the fluid flow and nonlinear updates. This results in an effective strategy that maintains solution accuracy and convergence behavior.
Intelligent Time-Stepping for Practical Numerical Simulation
Authors: Sheth Soham , McKee Francois , Neylon Kieran , Fazil Ghazala 
Published: October 2021

Abstract
We present a novel reservoir simulator time-step selection approach which uses machine-learning (ML) techniques to analyze the mathematical and physical state of the system and predict time-step sizes which are large while still being efficient to solve, thus making the simulation faster. An optimal time-step choice avoids wasted non-linear and linear equation set-up work when the time-step is too small and avoids highly non-linear systems that take many iterations to solve.
Typical time-step selectors use a limited set of features to heuristically predict the size of the next time-step. While they have been effective for simple simulation models, as model complexity increases, there is an increasing need for robust data-driven time-step selection algorithms. We propose two workflows – static and dynamic – that use a diverse set of physical (e.g., well data) and mathematical (e.g., CFL) features to build a predictive ML model. This can be pre-trained or dynamically trained to generate an inference model. The trained model can also be reinforced as new data becomes available and efficiently used for transfer learning.
We present the application of these workflows in a commercial reservoir simulator using distinct types of simulation model including black oil, compositional and thermal steam-assisted gravity drainage (SAGD). We have found that history-match and uncertainty/optimization studies benefit most from the static approach while the dynamic approach produces optimum step-sizes for prediction studies. We use a confidence monitor to manage the ML time-step selector at runtime. If the confidence level falls below a threshold, we switch to traditional heuristic method for that time-step. This avoids any degradation in the performance when the model features are outside the training space. Application to several complex cases, including a large field study, shows a significant speedup for single simulations and even better results for multiple simulations. We demonstrate that any simulation can take advantage of the stored state of the trained model and even augment it when new situations are encountered, so the system becomes more effective as it is exposed to more data.
