Published: January 2023

Для снижения материальных и временных затрат на разработку и внедрение технологии изготовления обшивок двойной кривизны с использованием процесса обтяжки листовых заготовок разработаны математические модели и методики, позволяющие производить цифровое моделирование процесса формообразования и корректировать его на раннем этапе разработки технологии. При разработке технологии изготовления окантовки двери на самолет SSJ-NEW применялись новые подходы к моделированию процесса формообразования, которые позволили определить наиболее оптимальную стратегию обтяжки крупногабаритной заготовки на пределе кинематических возможностей пресса FET-1500. Разработанная технология позволяет в рамках вычислительного эксперимента провести отработочные итерации с переходом на реальную обтяжку в оптимальных технологических параметрах.
To reduce material and time costs for the development and implementation of the technology for the manufacture of double-curvature sheets using the process of stretch-forming sheet workpieces, mathematical models and methods have been developed that allow digital modeling of the forming process and its correction at the early stage of technology development. When developing the technology for manufacturing the door edging on the SSJ-NEW aircraft, new approaches to modeling the forming process were used, which made it possible to determine the most optimal strategy for binding a large-sized workpiece at the limit of the kinematic capabilities of the FET-1500 press. The developed technology allows, within the framework of a computational experiment, to carry out working iterations with the transition to real binding in optimal technological parameters.

Published: January 2023

В статье рассматриваются вопросы моделирования процессов поверхностного наращивания тканых материалов. Выполнено обобщение модели, предложенной Н.Х.Арутюняном, на случай материалов чувствительных к зеркальным отражениям и инверсиям трехмерного пространства. Показано, что последовательные положения поверхности наращивания можно интерпретировать как поверхность уровня псевдоскалярного поля. Вводится понятия фундаментального ориентирующего псевдоскаляра и псевдоскалярного времени веса заданного целого веса. Обсуждаются вопросы вычисления единичного псевдовектора нормали к поверхности наращивания задающейся псевдоскалярным полем. Граничные условия для напряжений на поверхности роста, предложенные Г.И. Быковцевым, обобщены на случай псевдоскалярной геометрии. Приведены постановки простейших краевых задач, развиваемой теории и предложены методы их решения.
The article deals with the issues of modeling the processes of surface growth of woven materials. The generalization of the model proposed by N.Kh. Arutyunyan is carried out for the case of materials sensitive to specular reflections and inversions of three-dimensional space. It is shown that successive positions of the growth surface can be interpreted as a level surface of a pseudoscalar field. The concepts of fundamental orienting pseudoscalar and pseudoscalar time of the weight of a given integer weight are introduced. The issues of calculating the unit pseudovector of the normal to the growth surface given by the pseudoscalar field are discussed. The boundary conditions for stresses on the growth surface proposed by GI Bykovtsev are generalized to the case of pseudoscalar geometry. Statements of the simplest boundary value problems and the developed theory are given, and methods for their solution are proposed.
On two base natural forms of asymmetric force and couple stress tensors of potential in mechanics of hemitropic solids
Authors: Евгений Валерьевич Мурашкин, , Юрий Николаевич Радаев, 
Published: January 2023

В работе обсуждаются некоторые вопросы моделирования гемитропных упругих сред. Вводятся две основные квадратичные энергетические формы потенциала напряжений в терминах псевдотензоров. Указанные энергетические формы полагаются абсолютными инвариантами по отношению к произвольным преобразованиям трехмерного Евклидова пространства (в том числе, при зеркальных отражениях). В результате применения специальных координатных представлений полуизотропных (гемитропных) псевдотензоров четвертого ранга можно определить все 9 ковариантно постоянных определяющих псевдоскаляров, характеризующих гемитропную упругую среду. Выделены симметричные и антисимметричные части асимметричных тензоров и псевдотензоров деформаций и напряжений. Выполнено сравнение и получены соотношения, связывающие определяющие скаляры и псевдоскаляры первой и второй основных естественных энергетических форм, в том числе, с конвенционально используемыми гемитропными псевдоскалярами: модулем сдвига, коэффициентом Пуассона, характерной микродлиной (являющейся псевдоскаляром отрицательного веса, чувствительным к отражениям трехмерного пространства), и шестью безразмерными псевдоскалярами.
The paper is devoted to some problems concerning modeling hemitropic elastic media. Two main quadratic energy forms of a stress potential are introduced in terms of pseudotensors. These energy forms are assumed to be absolute invariants with respect to arbitrary transformations of the three-dimensional Euclidean space (including mirror reflections). As a result of applying special coordinate representations of semi-isotropic (hemitropic) pseudotensors of the fourth rank, it is possible to determine 9 covariantly constant constitutive pseudoscalars characterizing a hemitropic elastic medium. Symmetric and antisymmetric parts of asymmetric tensors and pseudotensors of strains and stresses are discriminated. The first and second base natural energy forms are compared and equations are derived for constitutive scalars and pseudoscalars, including the conventional hemitropic pseudoscalars: shear modulus, Poisson’s ratio, characteristic microlength (a pseudoscalar of negative weight, sensitive to reflections of three-dimensional space), and six dimensionless pseudoscalars.

Published: January 2023

Tax is the main indicator in the APBN because of the large percentage of tax revenue for maximum development in Indonesia. Taxes are obligations and expenses that reduce the company's net profit, this is contrary to the objectives of the entity. In 2020 the Director General of Taxes said that the implementation of tax avoidance resulted in losses to the state of up to 68.7 trillion per year. Therefore, many companies carry out tax avoidance measures. There are so many factors that can influence the occurrence of tax avoidance, including profitability, capital intensity, and debt to asset ratio. This study aims to determine the effect of the variables profitability, capital intensity, and debt to asset ratio on tax avoidance in property companies that are on the Indonesia Stock Exchange (IDX) for the 2018-2020 period. This study uses secondary data taken from the official website of the Indonesia Stock Exchange. The sample in this study used the nonprobability sampling which is purposive sampling technique, so that a sample of 17 companies was obtained with a total of 51 data. The analytical method used in this research is multiple linear regression analysis method. The results showed that profitability had no effect on tax avoidance, capital intensity had no effect on tax avoidance and debt to asset ratio had a significant positive effect on tax avoidance.

Authors: Nizzoli Cristina 
Published: January 2023

Cet article analyse les politiques publiques mises en œuvre sous le gouvernement Draghi pour soutenir le pouvoir d’achat des ménages (2021-2022), mais aussi les débats ayant traversé l’opinion publique et les organisations syndicales. La politique des primes fiscales et des bonus demeure la réponse privilégiée. Si d’autres pays ont connu des débats sur les revalorisations salariales, parfois accompagnés de mobilisations syndicales, l’Italie semble rester à l’écart de ce processus.

Referral pattern of children with cardiac diseases: a cross-sectional review of referral documents in three teaching hospitals in Addis Ababa
Authors: Aklilu Tamirat Moges 
Published: January 2023

Background: Patients with hemodynamically significant structural heart lesions often become inoperable if early referral and intervention is not done. Contrarily, referring patients with hemo-dynamically-insignificant lesions congest the already busy tertiary centers. The study aim was to determine the proportion of hemodynamically significant cases with delayed presentation and their determinant factors.
Methods: A cross-sectional study design was used to collect data from 369 referral slips sampled using a single population proportion formula (95% CI, 5% margin of error, and 50% cases coming with a referral paper). Data was analyzed using SPSS software package version 25. Binary logistic regression analysis was done to determine factors associated with referral either to the Tikur Anbessa hospital versus Saint Paul and Yekatit 12 hospitals. Odds ratio with their corresponding confidence interval was used to assess the significance of association and statistically significant associations were declared at p-value < 0.05.
Result: The overall magnitude of delayed presentation beyond 1 year of age among patients with hemodynamically-significant lesions was 54%. Saint Paul and Yekatit-12 hospitals combined had higher referral from primary institutions (AOR=2.68 95% CI-1.64-4.38, p<0.001). Tikur Anbessa hospital had higher referral of congenital heart disease and retention of feedback referral slips compared to the two hospitals (AOR=1.86, 95% CI-1.02-3.41, p=0.004) and (AOR=2.78, 95% CI-1.65-4.69, p<0.001). If the referring health worker was a specialist, and initial symptom was chronic and poly, the likely-hood of being referred to Tikur Anbessa Specialized hospital was higher (AOR=10.34, 95% CI-2.20-48.69, p=0.003) and 1.97, 95% CI-1.21-3.22, p=0.007) respectively. The time lapse between referral and reaching at the referral destination was longer in cases referred to TASH (AOR=2.91,95% CI-1.74-4.88), p<0.001). Feedback slips were sent back to the referring health facilities in only 3% of cases.
Conclusion: Delayed presentation of patients with hemodynamically significant cardiac lesions was tremendous. and unsent or retained feedback referral slips were significant. Future research should focus on active searching for causes of delayed presentation using a well-designed and validated tool.

Published: January 2023

Sex-reversal in Oreochromis niloticus is used to produce mono-sex males which are desired in aquaculture for better growth performances and population control. The present study was aimed at studying the effect of elevated fry rearing temperature on survival, sex ratios, and growth performances of O. niloticus populations of Lakes Chamo, Koka, and Ziway. Fries from five separate brood pairs of each population were either treated (T) in elevated fry rearing temperature of 36 ± 1°C or kept at room temperature of 24 ± 1°C as control (C) groups for 10 days (phase-I) and then grown in outdoor ponds for six months (phase-II). Survival rates in T groups (74.0 to 91.7%) were lower than that of C groups (83.3 to 97.0%) in all the three populations in phase-I but not in phase-II. Chamo population was better in survival rate (88.4% and 95.4% in Phase-I, and 95.4% and 95.3% in phase-II) than Koka population (85.8% and 91.3% in Phase-I, and 93.9% and 93.5% in phase-II) and Ziway population (80.2% and 88.6% in Phase-I and 90.2% and 91.9% in phase-II) both in T and C groups respectively. The Chamo population also attained significantly (p<0.05) higher mean final weight of 31.58 ± 6.78 g and 24.26 ± 6.67 g in T and C groups respectively, followed by that of Koka population with 21.70 ± 5.10 g and 18.83 ± 4.16 g while Ziway population with mean final weight of 17.49 ± 4.60 g and 16.81 ± 4.15 g was the least both in T and C groups. The overall sex ratios in T groups were skewed towards male but balanced in all C groups of each population. Better growth was achieved only in T groups with higher male ratio than their corresponding C groups. The number of sensitive brooding pairs and the overall male ratio in T groups were higher in the Koka population (40%, 61.68%) than in Ziway (20%, 56.78%) and Chamo (20%, 56.39%) populations respectively. However, the sensitivity of sex reversal to elevated fry rearing temperature was wide between individuals within each population than across the three populations. Hence, sensitive individuals can be selected from the populations and their degree of sensitivity can be improved through continuous selection of progenies from temperature-sensitive parents.

This research aimed to study the effect of garlic extract on the growth of stem cuttings of several types of bougainvillea and used a factorial randomized block design (RAK) with two factors. First factor is garlic extract in 2 levels, (with or without garlic extract). Second factor 2 is the type of bougainvillea consisting of 5 varieties such as yellow flowers, dark purple flowers, white flowers, red flowers and orange flowers. The results showed that the interaction between onion extract and bougainvillea had no significant effect on all observed variables (sprouting time, number of shoots, shoot length, number of roots, root length, percentage of cuttings sprouted and percentage of rooted cuttings). Garlic extract had no significant effect on all observed variables. There was a tendency for cuttings given garlic extract to show a faster age of budding, more shoots, longer roots and more roots. The type of bougainvillea gave a very significant effect on all observed variables except the number of shoots. Red flowers show the earliest age to start sprouting (16.80 days), the longest shoots (26.03 cm) and the longest roots (9.43 cm). Orange flowers performed the highest number of shoots (4.79), the highest percentage of shoots (96.67%) and the highest percentage of roots (96.67). Yellow flowers showed the latest sprouting time (37.08 days), the shortest shoot length (2.51 cm), the shortest root length (1.56 cm), and the least number of roots (1.06). Dark purple flowers showed the lowest percentage of budding and root percentage (63.33%).
