This manual describes the Pythia event generator, the most recent
version of an evolving physics tool used to answer fundamental questions
in particle physics. The program is most often used to generate
high-energy-physics collision “events”, i.e. sets of particles produced
in association with the collision of two incoming high-energy particles,
but has several uses beyond that. The guiding philosophy is to produce
and re-produce properties of experimentally obtained collisions as
accurately as possible. The program includes a wide ranges of reactions
within and beyond the Standard Model, and extending to heavy ion
physics. Emphasis is put on phenomena where strong interactions play a
major role. The manual contains both pedagogical and practical
components. All included physics models are described in enough detail
to allow the user to obtain a cursory overview of used assumptions and
approximations, enabling an informed evaluation of the program output. A
number of the most central algorithms are described in enough detail
that the main results of the program can be reproduced independently,
allowing further development of existing models or the addition of new
ones. Finally, a chapter dedicated fully to the user is included towards
the end, providing pedagogical examples of standard use cases, and a
detailed description of a number of external interfaces. The program
code, the online manual, and the latest version of this print manual can
be found on the Pythia web page: https://www.pythia.org/.
Arsenic removal using electrocoagulation followed by hematite granular filter
Authors: Ghosh Somaparna , Chaudhari Sanjeev 
Published: November 2022

Abstract
Drinking water contaminated with arsenic is a threat to human health. The present study attempts to remove arsenic using electrocoagulation with iron electrodes (ECFe) in continuous flow mode. Two experimental runs were separately conducted using untreated and treated (acid treatment followed by pH neutralization step) hematite as granular bed. The treatment of the hematite formed ferric oxy-hydroxides on hematite surface which was beneficial for arsenic removal. Total arsenic concentration reduced below 10 ppb from initial concentration of 500 ppb [As(III): As(V) = 1:1] with Fe dose of 5 mg/L after 48 h and 2 h of run conducted with untreated and treated hematite granular bed, respectively. The required Fe/As ratio of 10 was much lesser than the reported requirement of 250 in conventional systems. In the filter prototype using market-available filter cartridge, arsenic concentration reduced below 10 ppb from an initial concentration of 500 ppb [As(III): As(V) of 1:1] in both the absence and presence of phosphate (2 ppm) and silicate (30 ppm).

Authors: Nourbakhsh S.M.K. , Bahadoram M. , Eskandarion S. , Hassanzadeh S. 
Published: November 2022

Background. Acquired factor VIII (FVIII) deficiency or acquired hemophilia A (AHA) is very uncommon in children. Patients with AHA usually present with abnormal or unexpected bleeding which may be life-threatening. These patients usually have unexplained, prolonged, and isolated activated partial thromboplastin time (aPTT). Consequently, FVIII activity should be immediately evaluated. Bleeding prevention is important in patients with AHA.Case report. We present a case of a previously healthy 13-year-old female who presented with intramuscular hematoma, soft tissue hemorrhage, and epistaxis who was eventually diagnosed with AHA.Conclusion. To our knowledge, the present report is one of the few reported cases of an Asian patient that was diagnosed with acquired hemophilia A at a young age.

Published: November 2022

O pronunciamento técnico CPC 23 define os critérios para a retificação de erros de períodos anteriores, incluindo os elementos necessários em sua divulgação, assim, esse estudo tem o objetivo de analisar o modo como as empresas evidenciam a correção dos erros contábeis em suas notas explicativas, relativas aos exercícios de 2015 a 2018. Para tanto, foi realizada uma pesquisa descritiva, quanto aos seus objetivos, e documental, quanto ao seu delineamento. A análise documental centrou-se nas notas explicativas dos relatórios financeiros das empresas e a compilação de dados procedeu-se por meio da elaboração de checklist utilizando escores 0 e 1 para apontar o atendimento ou não aos requisitos de evidenciação do CPC 23 e na leitura exaustiva das notas, para análise do discurso nelas contidos. Também foi gerado um relatório de frequência de termos, para identificação de palavras-chave mais frequentes. Os resultados indicaram que, dentre os 149 erros identificados, a categoria “erros de registro” foi a mais frequente (100%), ao passo que só houve um registro de retificação de “erros de apresentação”, “erros de mensuração”. Quanto ao atendimento aos requisitos do CPC 23, houve equilíbrio entre três das quatro categorias (em apenas uma houve baixa evidenciação). O discurso presente nas notas é bastante marcado por uma tentativa de suavizar os efeitos dos erros, recorrendo-se a termos similares com menor impacto semântico, e por ressaltar os efeitos positivos das correções efetuadas.

Stability of multispan rods
Authors: Baragunova L. A. , Shogenova M. M. 
Published: November 2022

Objective. In the design of complex engineering structures, the problem of stability is now becoming especially relevant. With the need to meet the conditions of strength, rigidity in calculations and design, it is imperative to ensure the stability of equilibrium as the most important requirement. Regardless of the type of strength calculations (verification, design, load), the calculation of a structure for stability, even in the simplest formulation, is reduced to the determination of critical forces. This allows us to estimate the stability margin of the structure under a given load. The complexity of determining the critical parameters of the impact increases with the complexity of the system under consideration.Method. The use of the finite difference method is a feature in solving systems of equations in problems with boundary conditions.Result. The exact values of critical forces in non-classical problems of the stability of compressed rods are determined, which is proved by the obtained curve from the monitor screen.Conclusion. The main points of the theory of calculation in the study of the stability of multi-span rods are outlined. To find the critical forces of a multi-span rod on elastic supports, a simple algorithm for solving problems is given.

Published: November 2022

Objective. The purpose of the article is an experimental study of a thermoelectric system (TES) for the treatment of periodontal diseases by the method of local hypothermia.Method. An experimental stand and a technique for measuring prototypes of TEC for the treatment of periodontal diseases by the method of local hypothermia are described. The experimental stand is made on the basis of the measuring equipment of the laboratory of semiconductor thermoelectric devices and devices of the FSBEI HE "Dagestan State Technical University". In the first version of the TES, two thermoelectric modules (TEMs) are directly mated with the simulator of the periodontal area through a silicone layer, and in the second, thermal contact between the thermomodule and it is made through a special highly thermally conductive nozzle.Result. Graphs of the time dependence of the temperature change of the control points of the experimental samples of thermal power plants for the treatment of periodontal diseases by the method of local hypothermia at various TEM supply currents were obtained. The control points were the cold and hot junctions of the TEM, periodontal simulator, heat sinks from the hot junctions of thermal modules.Conclusion. As a result of the measurements, it was found that it is possible to achieve the required level of decrease in the temperature of the periodontal area using standard TEMs of the Kryotherm LLC (St. Petersburg) type TV-17-1.4-1.15 and DRIFT-1.2. In this case, the duration of the output of the samples to the regime in the first case is 230 s, and in the second - 320 s. The deterioration of the dynamic characteristics of the second version of the device is associated with the presence of a highly thermally conductive nozzle. As a result of full-scale tests, it was shown that the use of forced air and liquid cooling to remove heat from TEM hot junctions is sufficient to comply with the required temperature regimes of hypothermia.
