Published: March 2023

Bacteria is a potential agent in biological organic fertilizer”s process. The rate of decomposition of organic matter in biological organic fertilizers process depends on the role of funtional bacteria, the type of organic matter and the microenvironment.  Bacteria that are inoculated into biological organic fertilizer’s matter must be synergistic among them, so that their role as as bioactivators more efficient.  A compatibility experiment among the bacteria isolates used as bioactivators have to be done in order to  obtain an effective and efficient biological organic fertilizer. The objevctive of the research is to obtain information on the compatible nature of the bacterial isolates. The research was conducted at the Plant Protection Laboratory of the Payakumbuh State Agricultural Polytechnic, West Sumatra from July to August 2022. The research method began with the rejuvenation bacterial isolates of Bacillus cereus, Bacillus subtilis, Bacillus thuringiensis on NA media, then continued with a compatibility experiment  using the dual culture method on NA and King’s B medium, so there were a total of 12 treatments (single and combination) with three replications. The results of the compatibility experiment on the three Bacillus bacteria did not form a halo inhibition zone and were compatible with the compatibility index value (IK) 0.67-1 on NA medium and 0.90-1.00 on King’s B medium, meaning that the growth between the three Bacillus bacteria did not inhibit each other, so that all Bacillus bacteria could be used as a bioactivator simultaneously in biological organic fertilizer’s process.

Published: March 2023

Company XYZ targets an annual revenue of IDR 7.5 billion by 2025. The required growth rate at 70.17% annually is pretty high to achieve the target. However, the company’s actual growth in 2022 at 81.19% outperforms its sustainable growth rate at 29.28% and it seems achievable but requires aggressive expansion across operating systems, inventory, and marketing.   A Company with zero debt has a positive leverage to decide the financing strategy. The company observes to other comparable companies to decide the metrics and the value to select the financing strategy. In this research, we compare three commonly used financing strategies: equity financing, debt financing, and mixed financing. The metrics and requirements are the debt-to-equity ratio at a maximum of 17%, the current ratio at a minimum of 2.25, and the maximal Return on Equity. The selected option is the mixed financing strategy due to being able to meet all of the requirements even though the option did not have the cheapest option or the highest return on equity. The mixed financing strategy consists of full debt financing in the year 2023 and 2024 with a low-interest rate, while in the year 2025, the financing strategy is a combination between equity and debt. XYZ shall sell a maximum of 5.72% of its shares that brings capital at least equal to IDR 329 million and the remaining capital of IDR 329 million shall be raised through a bank loan with low-interest rates.

Public Health Measures Enacted by the Norwegian Political Leadership to Protect the Elderly in Response to the SARS-CoV-2 Pandemic Crisis
Authors: Tokovska Miroslava , Nour Magde Mohamed , Sørensen Anette , Ferreira Vanessa Nolasco
Published: March 2023

The SARS-CoV-2 pandemic crisis is ongoing, and the elderly are still affected by the virus, sometimes with fatal consequences. The political leaders are, inter alia, focussed on protecting citizens, including this vulnerable group. This article aims to describe the response of the Norwegian political leadership, with a focus on the public health measures enacted to protect the elderly during the SARS-CoV-2 pandemic crisis in the years 2020 and 2021. This study has a descriptive qualitative research design using thematic-content analysis as a methodology to evaluate data collected from official documents, national statistics and public health documents from Norway. Statistics show that the elderly mortality rate per 100,000 person-weeks during the first wave of the SARS-CoV-2 pandemic was 2.69 in Norway; during the second wave of the pandemic, it was 1.43. The public health measures the Norwegian political leadership instigated were more effective in containing the crisis when compared to other European countries, and this paper investigates the reasons. The results of our study provide public health policy decision-makers with insights into analytical material showing the usefulness of different measures enacted by the Norwegian government. The Norwegian government’s responses to the crisis, such as the public health measures, restrictions, social consequences for vulnerable groups such as the elderly, as well as cross-government and cross-community cooperation, will need further in-depth analysis.

Published: March 2023

Background: Data regarding cardiac damage in Romanian hypertensive adults are scarce. Our aim was to assess hypertension-mediated subclinical and clinical cardiac damage using a post-hoc echocardiographic analysis of a national epidemiological survey.

Methods: A representative sample of 1477 subjects was included in the SEPHAR IV (Study for the Evaluation of Prevalence of Hypertension and Cardiovascular Risk in an Adult Population in Romania) survey. We retrieved echocardiographic data for 976 subjects, who formed our study group. Cardiac damage included left ventricular (LV) hypertrophy (defined as an LV mass > 95 g/m2 in females and > 115 g/m2 in males), coronary artery disease (CAD), and LV diastolic and systolic dysfunction.

Results: Hypertension prevalence was 46.0% in SEPHAR IV and 45.3% in our study subgroup. Hypertensives had a higher prevalence of LV hypertrophy, CAD, diastolic dysfunction (p<0.001 for all) and systolic dysfunction (p=0.03) than normotensives. Age (OR=1.05;95% CI,1.03–1.08;p<0.001), female sex (OR=2.07;95% CI,1.24–3.45;p=0.006), and systolic blood pressure (OR=1.02;95% CI,1.01−1.04;p=0.026) were independent predictors of LVH in hypertensives. Age was a predictor of diastolic dysfunction (OR=1.04;95% CI,1.02−1.06;p<0.001), and female sex was a protective factor against systolic dysfunction (OR=0.26;95% CI,0.10–0.71;p=0.009). Age (OR=1.05;95% CI,1.02−1.07;p<0.001) and dyslipidemia (OR=1.89;95% CI,1.20–3.00;p=0.007) were independent determinants of CAD in hypertensives.

Conclusion: The prevalence of cardiac damage in Romanian hypertensives is high. Both non-modifiable risk factors (such as age and gender) and modifiable (such as dyslipidemia and systolic blood pressure) risk factors are independent predictors of cardiac damage in hypertensives.

Authors: Hadadi László , Toma Roxana , Pop Marian , Blesneac Cristina , Sglimbea Anca Ioana
Published: March 2023

Introduction: Acute thrombosis of the modified Blalock-Taussig shunt (mBTS) in patients with univentricular physiology is a life-threatening event.

Case presentation: We present a case of acute mBTS thrombosis complicating a hemodynamic evaluation before a bidirectional Glenn procedure for tricuspid atresia. After failed balloon angioplasty and catheter-directed selective thrombolysis, the patient was successfully managed by stent implantation into the thrombosed shunt. To the best of our knowledge, this was the first case of acute mBTS thrombosis treated by catheter intervention in Romania.

Conclusions: Even a routine invasive hemodynamic evaluation might be complicated by a life-threatening condition. Stent implantation in the setting of acute mBTS thrombosis could be lifesaving.

Authors: Rausky María Eugenia , Pi Puig Pilar , Aliano Nicolás
Published: March 2023

Objetivo: analizar las prácticas alimentarias desplegadas por los referentes de comedores y ollas populares de Argentina durante la pandemia por Covid-19. Metodología: el abordaje es cualitativo y la selección de los sujetos incorporados al estudio se basó en el muestreo intencional. 63 entrevistas en profundidad en ocho barrios populares del Gran La Plata (Buenos Aires). Resultados: se describe el entrelazamiento tanto de recursos económicos y organizativos, como de saberes locales y hábitos culinarios que se activaron ante la situación de emergencia alimentaria. Se muestra que el hecho de alimentar en contextos populares durante la pandemia ha sido una práctica colectiva compleja, diversa e inscripta territorialmente. Limitaciones: la emergencia sanitaria y las medidas de restricción a la circulación, limitaron la posibilidad de complementar el análisis de las prácticas alimentarias reconstruidas discursivamente con su observación directa en campo. Conclusiones: las prácticas desplegadas por los referentes de comedores y ollas populares no se limitaron a la mediación pasiva entre la asistencia alimentaria estatal/civil y los hogares, sino que se inscribieron en las formas de organización y liderazgo barriales, dialogaron con las culturas locales y supieron interpelar los “gustos” nativos. De allí que su desempeño fuera considerado eficaz, cubriendo una necesidad alimentaria, como así también oficiando de soporte social y emocional clave frente a un contexto de incertidumbre de los hogares.

Published: March 2023

The article  presents  an analysis of literature data  on modern  protective regimens  for invasive respiratory support  in premature newborns  with respiratory distress  syndrome. We have considered positive and negative  aspects of the used methods  of invasive ventilation of the lungs, which are currently widely used as a method  of respiratory therapy  in obstetric hospitals  at any level, even in the category  of children  with extremely and very low birth weight. Modern  protective mechanical ventilation provides for 2 main directions for reducing ventilator-induced lung damage: a decrease in tidal volume (Vt) and the principle  of tolerable  (permissive) hypercapnia. The use of the technique of permissive hypercapnia and regimens with a target volume can reduce the likelihood of ventilator-induced lung injury in newborns. Despite the limited indications for mechanical ventilation in modern neonatology and the widespread use of non-invasive ventilation, for patients who really need mechanical ventilation, the use of volume-targeted regimens offers the best chance of reducing  ventilation complications.

Authors:   University of Belgrade, Milanović Vesna , Bílek Martin ,   Charles University, Prague
Published: March 2023

The course Chemistry as part of society through centuries was offered as an elective course to students future teachers at Faculty of Education Charles University in Prague. It was special challenge for them because the course was organized in English language with lecturer from the University of Belgrade – Faculty of Chemistry realising post-doc stay here. The main aims of the course were that students: (i) become familiar with historical development of chemistry as part of the society, (ii) learn about important discoveries from the past and scientists creditable for these discoveries, (iii) enrich understanding the nature of science. The syllabus encompassed twelve topics that covered period from prehistory to the 20th century. In order to monitor students’ progress, they were tested by the same test in the beginning and in the end of the course. Students’ exam task was to write an essay about self-chosen topic from history of chemistry. The course was enrolled by 33 students. Three topics were elaborated in the classroom, while others were realized in distance form through video-presentations and other teaching materials. By comparison of students’ answers in the initial and final test, it can be concluded that they improved knowledge about chemical discoveries from the past, and some views on the nature of science. The students wrote essays on different topics, but the topics women in chemistry and Czech scientists were more frequent than others.

Authors:   Charles University, Prague, Sadykov Timur , Čtrnáctová Hana ,   Charles University, Prague
Published: March 2023

Interactive apps allow educators to teach without being restricted by time and place, enabling learning in or outside the classroom in places where learning occurs naturally (Huang, Lin,& Cheng, 2010). They also give the teacher the ability to connect with learners on a more personal level with the help of mobile digital devices that the learners use on a regular basis (Ward et al.,2013). In addition, these apps make learning fun through friendly competitions, challenges, making it an excellent means of encouraging students’ engagement in learning (Ding, Er &Orey, 2018). This contribution investigated whether the use of mobile interactive apps influenced students’ opinions and boosted their engagement in the chemistry. It covers about 15 popular, mostly free apps that can be used to learn chemistry. The first verification was carried out from December 2018 to January 2019 with specialized school-board information technologies in Karaganda (Kazakhstan). The results showed that more than 70 % of the students (8-9th grade) enjoy working with interactive apps,which positively affects their opinions towards the subject. In the next part, we will therefore focus on verification of the use of interactive apps in the Czech Republic.
REFLECTING UPON MEASURED DATA AT THE AGE OF 12
Authors:   Comenius University in Bratislava, Šromeková Karolína , Demkanin Peter ,   Comenius University in Bratislava
Published: March 2023

The paper presents our experience with a physics teachinglearning sequence for pupils at the age of 12. The sequence is an existing activity titled “How to measure a ball?”, which focuses on introducing physics quantities and the units in which they are measured.The activity is part of the “ExpEdícia -skús, skúmaj a spoznaj” (ExpEdition -experience, inquire, uncover) pilot programme which implements a participative, holistic model of teaching which nurtures pupils’ innate curiosity, similar to the constructivist approach to teaching mathematics called the Hejny method. The essential requirement is sufficient time for developing experiences and seeking answers to questions that are of interest to the pupils. An analysis of a 6th grade primary school physics lesson where the activity was used allows us to retrospectively consider the way pupils build up their knowledge and how a teacher can contribute to this. We note that the activity extends over to other areas of physics beyond those explicitly covered in the activity. These forays are made available thanks to the participative model chosen. We also look at the mathematical side of the activity and look for connections between mathematics and physics which individual students gradually build up.

Following the decision to divide Upper Silesia between Germany and Poland, detailed regulations were established according to which individual counties were supposed to be taken over by both states. Major celebrations on the German side were held in the summer of 1922 in Opole, where the official assumption of control over the German Upper Silesia by the government of the German Reich took place. The legality of the actions undertaken in the Upper Silesia by the victorious western states was undermined and postulates were put forward to peacefully revise the course of the border established in the wake of the plebiscite and the Silesian Uprisings. In his article, the author presents this issue, as seen from the perspective of the then German press.

Notes written and edited by rev. Joachim Besler, SVD, chaplain of the Katowice prison between 1942 and 1945, and stored at the Archives of the Archdiocese of Katowice, constitute an important testimony of the last moments of the life of Blessed rev. Jan Macha and two of his co-workers, Joachim Gűrtler and Leon Rydrych. The notes are also an important source enabling us to broaden our knowledge on the people guillotined in the Katowice prison and bringing a lot of detailed information on the functioning of this institution itself as the place of martyrdom of the Polish population of Upper Silesia in the times of the German occupation. Rev. Besler started his service as chaplain in this prison on 28 July 1942 and worked there until January 1945, when Red Army troops entered Katowice. According to his memoirs, he had prepared about five hundred people for death, most of whom were Polish, but there were also some Germans, Italians and Frenchmen. He also remembered several women whose confession he had taken before their execution. All the prisoners were brought over to Katowice from various prisons in the provinces of Katowice and Opole, such as Bielsko, Cieszyn, Strzelce and Racibórz. At that time, rev. Besler took conspiratorial notes on the people sentenced to death and on their death circumstances. The notes were then used to create a manuscript, which was subsequently re-written and stored in the archives. The document has already been quoted by historians, but it has never been published as a whole.
FECAL CALPROTECTIN AND URINE EOSINOPHIL PROTEIN X CONCENTRATIONS IN INFANTS DEPENDING ON INTERLEUKIN 10 (G1082A, C592A) AND TOLL-LIKE RECEPTOR 4 (ASP299GLY) GENE POLYMORPHISMS

Background. Cytokine and toll-like receptor gene polymorphisms may impact oral tolerance formation in infants. Objective: To determine the genotype distribution of IL-10 (G1082A, C592A) and TLR 4 (Asp299Gly) gene polymorphisms in children with different family history of allergy residing in Grodno region; to analyze the association between gene polymorphisms and concentrations of fecal calprotectin (FCP) and urine eosinophil protein X (UEoPX) in infants. Material and Methods. 92 infants were recruited and analyzed for IL-10 (G1082A, C592A) and TLR 4 (Asp299Gly) gene polymorphisms. Concentrations of FCP and UEoPX were examined in dynamics in children aged 1 and 3 months. Results. 80.4% and 48.9% of infants were carriers of the mutant allele of the G1082A and C592A polymorphisms respectively. 70.5% of children with negative family history of allergy were carriers of the wild G allele of G1082A polymorphism. Carriage of the mutant A allele of G1082A polymorphism is associated with lower FCP concentration in infants aged 1 month (AA: 1.9 ng/mL [1.9; 3.1], GA: 15.9 ng/mL [1.9; 93.8]) and GG: 88.3 ng/mL [2.4; 230.1]). The level of UEoPX in 3 months old infants with homozygote AA genotype was significantly (p=0.019) higher than in infants with heterozygote CA genotype (3.2 ng/ml [2.4; 4.5] and 2.3 ng/ml [1.3; 3.3] respectively). Conclusion. Carriage of the wild G allele of G1082A polymorphism is associated with higher fecal calprotectin concentration in one month old infants and significantly lower level of urine eosinophil protein X in 3 months old infants.

Coronavirus infection has had a significant impact on people around the world, however, there is a category of patients who are at high risk of severe disease - kidney transplant recipients. The high risk is due to the presence of a pronounced comorbid background, long-term background immunosuppression, a high risk of secondary infection, and graft dysfunction as a result of a severe infection. This paper presents a series of clinical cases of severe COVID-19 infection in kidney transplant recipients. We have demonstrated that timely diagnosis and intensive therapy, including both adequate drug therapy and the use of renal replacement therapy in the form of hemodialysis and extracorporeal detoxification methods, can not only save the lives of such patients, but also preserve a functioning kidney transplant.

BOUNDARY VALUE PROBLEMS FOR TWICE DEGENERATE DIFFERENTIAL EQUATIONS WITH MULTIPLE CHARACTERISTICS

Работа посвящена исследованию разрешимости краевых задач для вырождающихся дифференциальных уравнений вида $$varphi(t)u_t-(-1)^mpsi(t)D^{2m+1}_{x}u+c(x,t)u=f(x,t)$$ ($D^k_x=frac{partial^k}{partialx^k,,mgeq 1}$ целое, $xin(0,1),, tin(0,T),,0<T<+infty,$ называемых уравнениями с кратными характеристиками. В этих уравнениях функция $varphi(t)$ может менять знак на отрезке $[0, T]$ произвольным образом, функция $psi(t)$ предполагается неотрицательной. Для изучаемых уравнений предлагаются постановки краевых задач, существенным образом определяющиеся числами $varphi(0)$ и $varphi(T)$, и для предложенных задач доказываются теоремы существования и единственности регулярных (имеющих все обобщенные по С. Л. Соболеву производные, входящие в уравнение) решений.

We study the solvability of boundary value problems for degenerate differential equations of the form $$varphi(t)u_t-(-1)^mpsi(t)D^{2m+1}_{x}u+c(x,t)u=f(x,t)$$ ($D^k_x=frac{partial^k}{partialx^k,,mgeq 1}$ is an integer, $xin(0,1),, tin(0,T),,0<T<+infty,$ called equations with multiple characteristics. In these equations, the function $varphi(t)$ can change the sign on the interval $[0, T]$ arbitrarily, while the function $psi(t)$ is assumed nonnegative. For the equations under consideration, we propose the formulation of boundary value problems which are essentially determined by numbers $varphi(0)$ and $psi(T)$. Existence and uniqueness theorems are proved for the regular solutions that have all Sobolev generalized derivatives entering into the equation.

Получено решение однородного дифференциального уравнения дробного порядка типа Эйлера на интервале в классе функций, представимых дробным интегралом порядка $\alpha$ с плотностью из $L_1(0; 1).$ С помощью метода эрмитовых форм (метода Льенара-Шипара) получены условия разрешимости для случаев двух, трех и любого конечного числа производных. Показано, что в случае, когда характеристическое уравнение имеет кратные корни, исходное уравнение допускает решение с логарифмическими особенностями.

We present the solution of the homogeneous fractional differential Euler-type equation on the half-axis in the class of functions representable by the fractional integral of order $\alpha$ with the density of $L_1(0; 1).$ Using the method of Hermitian forms (Lienard–Schipar’s method), solvability conditions are obtained for the cases of two, three and a finite number of derivatives. It is shown that in the case when the characteristic equation has multiple roots original equation admits a solution with logarithmic singularities.

We discuss a single-phase radial viscous ﬁngering problem in a Hele–Shaw cell, which is a nonlinear problem with a free boundary for an elliptic equation. Unlike the Stefan problem for heat equation Hele–Shaw problem is of hydrodynamic type. In this paper a single-phase Hele–Shaw problem in a radial ﬂow geometry admits a unique classical solution by applying the same method as for Stefan problem and justifying the vanishing the coeﬃcient of the derivative with respect to time in a parabolic equation.
Improvement of Neustadt-Eaton’s method convergence

Нейштадт и Итон разработали метод и численный алгоритм решения задачи оптимального быстродействия. В этом методе необходимо решать дискретное уравнение для нахождения начального значения сопряженной системы. В ходе решения этого уравнения на каждом шаге нужно находить величину приращения начального значения сопряженной системы. Это достигается путем выбора длины шага. При этом начальное значение сопряженной системы должно удовлетворять определенным условиям. Затем решается система дифференциальных уравнений, где в качестве начальных данных используются полученные значения сопряженной системы и определяется траектория. Таким образом, на каждом шаге решения дискретного уравнения необходимо использовать итерационный процесс. Доказана сходимость метода. При этом нужно отметить слабую сходимость метода. Для улучшения сходимости предлагается следующий подход. Делается несколько шагов метода Нейштадта-Итона. Полученные начальные значения сопряженной системы аппроксимируются и экстраполируются на определенном интервале. Затем снова делаем несколько шагов метода Нейштадта-Итона и при этом используем экстраполированные значения начальных значений сопряженной системы. Таким образом, предлагается <<скользящая>> аппроксимация найденных решений дискретного уравнения для каждой компоненты с помощью алгебраической функции с последующей ее экстраполяцией. Экстраполяция позволяет значительно уменьшить вычислительные затраты.

Neustadt and Eaton developed a method and an iterative algorithm for solving time-optimal control problems. According to the method, it is necessary to solve a discrete equation to find the initial value of the adjoint system. At each step of the algorithm it is needed to find the increment of the initial value of the adjoint system. This is achieved by choosing the step length, while the initial value must satisfy certain conditions. Then the system of differential equations is solved, where the obtained values are used as initial data and the trajectory is determined. Thus, the iterative process must be used on each step of solving the discrete equation. The convergence of this method was previously proved. However, the convergence is weak. To improve it, the following approach is proposed. After a few steps of Neustadt-Eaton’s method the obtained initial values of the adjoint system are approximated and extrapolated at a certain interval. Then again we take a few steps of Neustadt-Eaton’s method and use the extrapolated initial values of the adjoint system. Thus we propose <> approximation of the discrete equation solutions for each component using an algebraic function followed by extrapolation. It is shown that such extrapolation significantly reduces computational costs.
