A Block Solver of Variable Step Variable Order for Stiff ODEs
Authors: Oghonyon Jimevwo Godwin , Abodunrin Temitope , Ogunniyi Peter Oluwatomi
Published: July 2022

A block solver of variable step variable order (BSVSVO) is suggested for stiff ordinary differential equations (ODEs). The block solver is employed to enhance the performance for stiff ODEs via variable step variable order to achieve faster convergence with better accuracy and lesser maximum error. Block solver is formulated via interpolation and collocation together with power series as the basis function approximation. The principal local truncation error (PLTE) of the block solver is utilized to generate the convergence criteria. Some investigation of the theoretical properties will be mentioned and analyzed. The block solver will be implemented using some selected test problems and compared with existing methods to showcase the convergence, high efficiency and accuracy thereby ensuring a better maximum error of the suggested method.

Published: July 2022

Thinning treatment is a necessary and complex forestry activity. The experimental results from plantations established 20-30 years ago and explains some concepts of the theory, practice, methods, and regime of thinning on the permanent sample plots of pine stands in Gatchinsky forestry of the Leningrad region were shown in this article. Choosing the right thinning method allows to optimize the yield, productivity and mortality of the stand. On the other hand, we observed improved merchantability of the stand, reduced time for forestation, and simplified thinning programs. Crown thinning is a less preferred method than bottom thinning, as it leads to a deterioration in the quality of trees and an increase in their mortality. The inexpediency of preliminary thinning of trees has been established. Tree thinning results in an improvement in the quality of the remaining stand, as nutrient utilization is greatly increased. Tree thinning must necessarily be combined with fertilization. Thinning without fertilization and fertilization without thinning show the worst results. In general, findings of this article can be used to improve approach of thinning treatment in the Leningrad or other regions in the North of Russian Federation.
Mathematical Modelling and Simulation Analysis of an Aircraft Wing Using SimMechanics
Authors: Laiche Atif , Boulahia Allaoua
Published: July 2022

Flexible structures outperform rigid ones thanks to their lightweight, dexterous maneuverability as well as their suitability towards high vibration. To this end, a rectangular-shaped wing is modeled as a flexible cantilever beam under two loading conditions, namely the former is a uniformly distributed force which is triggered by gravity while the latter is a tip load. In the same context, this paper addresses the lumped parameter method (LPM) for modeling a flexible wing using SimMechanics (also called Simscape Multibody) and Simulink environment by considering the wing as a concatenation of small elements connected together through springs and dampers. To verify the proposed model, simulation examples are carried, from which it is found that the simulation results approximately match the analytical findings. To emphasis, comparatively speaking, the obtained results from SimMechanics model provides with the same results as in modal analysis which is performed through Ansys workbench, namely the achieved deflection as well as modes shape from the conventional formulas fit in with the deflection obtained from the developed model in SimMechanics.
DOE-ANOVA for Identifying the Effect of Extreme Sea-States over the Structural Dynamic Parameters of a Floating Structure
Authors: Rueda-Bayona Juan G. , Guzmán Andrés , Osorio Andrés F.
Published: July 2022

Sea extreme events affect the integrity and operation of the offshore structures, then, it is important to analyze wind-waves-currents loads over the structural dynamics. Traditional offshore designing identifies structural parameters with certain limitations: physical modeling involves using shaking tables in dry conditions; numerical simulations have not sufficiently considered the effects of combined extreme waves-wind-current loads over the structure and the significance of the near and far hydrodynamic field over the structure. The non-linear interactions in the near hydrodynamic field generate viscous damping that modifies the dynamic structural parameters of the offshore structures. The traditional determination of structural parameters considers the hydrodynamic forces computed from wave records, omitting fluid-structure interactions that could generate unexpected damped periods and amplification peaks. This study applied physical modeling to determine floating structural parameters, considering combined loads and the effect of far and near hydrodynamic field in the fluid-structure interaction. The calculated transfer functions in the near hydrodynamic field revealed the highest amplification of the structural accelerations, and the transfer functions in the far field did not evidence structural resonance. Finally, this study recommends measuring the near hydrodynamic field and applying DOE-ANOVA for offshore designing to assess the viscous damping that may provoke dangerous structural amplifications.

Published: July 2022

Modifying additives impact – pro-oxidants – on low-density polyethylene oxidative degradation under short-term aging conditions in a thermostat with forced convection at 70 °C and ultraviolet irradiation with different exposures (48, 96, 144 h) was studied. It is concluded that for polyethylene films modified with stearates of metals of variable valence, under short-term aging conditions, the formation of aldehydes (1733–1740 cm-1) and carboxyl (1700 cm-1) was observed and accompanied by a sharp decrease in the intensity of absorption bands at 1465–1470 cm-1, which is specific to stretching and bending deformations of CH2 of the polyethylene polymer matrix and indicating the destruction of polymer chains. It is shown that the short-term aging of oxidatively biodegradable polyethylene affects environmental and technological problems associated with the pollutants release, including in particular, formaldehyde and other pollutants.

Authors: Starostina I.V. , Kiryushina N.Yu. , Loktionova Е.V. , Matushkina А.V.
Published: July 2022

A method of obtaining a composite ferrosilicon flocculant-coagulant (FSFC) as a result of acidic modification of slaking steelmaking slag was suggested. It has been determined that the acidic modification of electric-furnace steelmaking slag results in the leaching of basic oxides with the formation of ferric sulfate and silicic acid gel. This allows using the obtained modification product as a ferrosilicon flocculant-coagulant in emulsified wastewaters purification systems. It has been demonstrated that the obtained powdery FSFC at the consumption rate 0.7 g/dm3 provides the emulsion purification efficiency – 99.3 %.

Na podlagi slovanskih parnih glagolskih dvojnic (tj. variantnih dvojnic), ki se v svojih leksičnih in gramatičnih pomenih prekrivajo, se ugotavlja, da so nastale s prehodom (preskokom) iz nižje glagolske vrste v višjo, izofunkcijsko (tj. iz I. vrste → II. in/ali III. vrsto; iz II. vrste → III. vrsto). Sodeč po smeri poteka je najverjetnejši vzrok analogne spremembe različna produktivnost glagolskih oblik po vrstah, tj. nižja produktivnost izhodiščnih dvojnic in višja produktivnost ciljnih dvojnic. Pri morfološkem prestrukturiranju (tj. prehodu med glagolskimi vrstami) ciljna dvojnica prevzame tudi prozodične in morfološke lastnosti ciljne glagolske vrste.
A Regional Dictionary as a Source in Research into the Dynamics of Linguistic Changes
Authors: Osowski Błażej
Published: July 2022

The situation of subdialects is, currently, a very dynamic subject as a result of their regular contact with the standard variety of the language, linguistic integration and interference. A regional dictionary is a concept of a subdialect dictionary which registers the contemporary state of a language spoken in a village or a small region. It contains regional, colloquial and special words, as well as elements of traditional subdialects. This article introduces the idea of a regional dictionary and the opportunities it poses for studying changes in rural language. There are references to the dynamics within a dictionary (the vocabulary obtained from representatives of different generations) and comparisons with earlier sources.

Predictability of Stock Returns in Central and Eastern European Countries
Authors: Pietraszewski Piotr
Published: July 2022

Stock return predictability in highly developed countries has both empirical and theoretical justification in financial literature. The article aims to answer the question if market valuation ratios that relate share prices to various accounting quantities have any predictive power for long-term stock index returns on investments in capital markets of some Central and Eastern European countries, namely the Czech Republic, Hungary, Poland, and Russia. Heteroskedasticity and autocorrelation-consistent estimators with a small-sample degrees of freedom adjustment were used in regressions to track the overlapping data problem and small sample bias. The results of an investigation show that some of these ratios, such as price to a ten-year moving average of real earnings, commonly known as the cyclically adjusted price earnings (CAPE) ratio, price to estimated profits, market to book value and price to sales revenues have a strong predictive power for cumulative returns mainly over long horizons. On the other hand, price to one-year earnings, dividend yield or price to cash flow ratios prove to be quite poor predictors. Following the arguments of behavioural finance, we conclude that the evidence obtained in the study proving a fairly significant link between current values of market ratios and future cumulative returns indicates a certain degree of ineffectiveness of the analysed markets during the examined period.
Measuring Creativity in the Fermi Problem, a Type of Mathematical Modelling, Applying Information Theory
Authors: Okamoto Hidemichi
Published: July 2022

Many methods of measuring creativity have been studied - mainly in psychology. In recent years, there have been attempts to incorporate such creativity into mathematical modelling, a topic handled in mathematics education. Accordingly, some studies have been trying to assess creativity in it. However, there have been no clear criteria or formulas that can be used for any problem, since a rubric has been created for each problem and evaluated individually. In the present study, to measure creativity in the Fermi problem, a type of mathematical modelling, a formula that applies information theory used in information science is proposed and examined using Structural Equation Modeling (SEM). A survey of Japanese junior high school students (n = 364) was conducted and analyzed, and the results show that the model using the formula proposed in the present study is a good fit. In addition, a moderate positive correlation (r = .41, p < .01 ) is found between creativity in the Fermi problem and creativity in psychology measured by the Test for Creative Thinking-Drawing Production (TCT-DP).

This study aims to analyze the accountability and transparency of mosque financial management in the city of Malang, especially in mosques managed by the academic and non-academic community. The objects of this research are 4 Great Mosques in Malang City, namely AR Fachruddin Mosque, An-Nur Polytechnic Mosque, Abu Dzar Al Ghifari Mosque, and Sabilillah Mosque. This research uses descriptive qualitative method. Collecting data in this research is observation, interview and documentation. Sources of data in this study are primary data and secondary data. This research is motivated by mosques which usually only present financial reports which only include revenues that are generally obtained from the congregation and cash disbursements. The source of the mosque's funds cannot be clearly identified for what purpose the funds are used. The results showed that all mosques already had financial reports as a form of accountability. The mosque's financial manager has complied with the values of sharia accounting principles: accountability, justice and truth. These three principles are related to the characteristics possessed by the apostle: sidiq, amanah, tabligh and fathanah. Although, this study found that accounting practices are still not in accordance with accounting standards for non-profit entities. This is because the financial manager does not have a financial background. Most of the mosque's financial publications are announced just before Friday prayers and posted on the wall magazine.
Biological Psychiatry and the Mass Murder of “Schizophrenics”: From Denial to Inspirational Alternative
Authors: Read John , Masson Jeffrey
Published: July 2022

This article documents the murder, by psychiatrists, of a quarter of a million patients, mostly diagnosed as “schizophrenic,” in Europe during the second world war; and the sterilization of hundreds of thousands more internationally, including in the USA and Scandinavia. These sterilizations and murders were justified by biological psychiatry’s unsubstantiated hypothesis that the conditions involved are genetically determined. Gas chambers in the six psychiatric hospitals involved, in Germany, were subsequently dismantled and moved, along with the psychiatrists and their staff, to help establish some of the Holocaust’s concentration camps, in Poland. The avoidance of these facts and their profound implications, by the profession of psychiatry, internationally, over subsequent decades, is discussed. An inspirational trauma-focussed alternative to the pessimistic, unscientific ideology of biological psychiatry, involving psychiatrists 60 years later, is presented.
Adverse Maternal and Perinatal Outcome of Women Aged 40 Years or Over: A Retrospective Study
Authors: Karai Adrienn , Gyurkovits Zita , Németh Gábor , Orvos Hajnalka , Paulik Edit
Published: July 2022

BACKGROUND

Advanced maternal age is traditionally described to be 35 years of age or over. In recent years, new trends have suggested that it may be 40 years of age or over; this occurs in Hungary.

AIM

The aim of this study was to determine the association between advanced maternal age and various adverse maternal and neonatal outcomes.

METHODS

A retrospective analysis was performed among women who delivered between 2015 and 2017. All women aged 40 years or over (cases) were involved into the analysis (n = 374). The controls (n = 378) were randomly selected from women aged 25 to 29 years who delivered during the same period considering the number of previous gestations and previous deliveries. The data collected from the medical records comprised the mothers’ demographic and obstetric characteristics and neonatal data. To assess the contribution of maternal age to various maternal and neonatal outcomes, multiple logistic regression analyses were used.

RESULTS

The logistic regression analyses showed higher odds of gestational diabetes (AOR, adjusted odds ratio: 2.81), preeclampsia (AOR: 13.05), threatened preterm delivery (AOR: 3.62), and cesarean section (AOR: 3.31) in mothers of higher age. The odds of low birth weight (AOR: 2.56) and intensive care (AOR: 2.03) were significantly higher in older vs. younger mothers, while no significant associations were between maternal age and fetal macrosomia and congenital malformations.

CONCLUSIONS

Considering our results, it is important to educate women about the consequences of delayed childbearing and the need of continuous observation within prenatal care.

Published: July 2022

Background: Melasma, or chloasma, is an acquired pigmentary disorder caused by increased melanin in the epidermal and dermal layers, characterized by brown or gray patches on the face and neck. There are many treatment options available; however, the difficulties in treating melasma are frequent recalcitrants, high recurrence rate, irregularity in treatment, and the tendency of the patients to self-medicate. Case Ilustration: We report a case of mixed melasma treated by microneedling and topical PRP administration. Thirteen weeks following the therapy, the patient showed a favorable response brighter skin and substantial disappearance of brown patches. Discussion: Studies assessing the efficacy of microneedling and platelet-rich plasma (PRP) treatment for melasma are still lacking. However, melasma improvement has been reported in patients treated with microneedling and PRP. In this study, we provided a study of a patient with mixed melasma treated by microneedling and PRP, which showed a favorable improvement. Conclusion: Microneedling and PRP treatment showed a favorable response in a patient with melasma, with substantial disappearance of brown patches and a decrease in MASI (Melasma Area and Severity Index) score. Keywords: microneedling, mixed melasma, platelet-rich plasma

The availability of additional education for children and youth is one of the important factors in ensuring the social integrity and stability of the development of each region and the country as a whole. Accessibility of additional education is characterized, first of all, by the scale of participation of children and youth in additional education programs. This article examines the features of rural children's participation in additional education: coverage in general, at school and outside of school by various forms of educational programs. The article provides an analysis of various parameters of the involvement of children living in rural areas in additional education. According to the data of the study, the involvement of children in rural areas in classes on additional general education programs implemented in anetwork form is less than in urban areas. The geography of the study is quite extensive: more than forty-five thousand students from fifty-one subjects of the Russian Federation took part in the survey. The article also analyzes the results of a survey of schoolchildren’s parents on the subject of satisfaction with the educational services received when mastering additional general development programs of all directions in educational organizations. The article describes the assessment of the participation of rural schoolchildren in additional education in the context of various directions, forms of participation, age and gender of children. Changes in the possibilities of obtaining additional education for children in rural areas within the framework of federal projects are discussed. The features of infrastructural and personnel support of additional educational programs implemented in rural areas are considered.

Published: July 2022

La insuficiencia venosa crónica (IVC) es una patología vascular frecuente en el adulto mayor, y genera dificultades en su diagnóstico y tratamiento debido a la presencia de comorbilidades. Se realizó una revisión narrativa a partir de la búsqueda en cinco bases de datos: PubMed, Scielo, Lilacs, Clinical Key (Elsevier) y Ebsco. En la población geriátrica se presentan estadios más severos de la enfermedad, como el edema y los cambios tróficos en la pierna, debido a la preexistencia de enfermedad venosa crónica. Los principales factores de riesgo de progresión de la enfermedad son la obesidad, la movilidad limitada y las comorbilidades. El diagnóstico se basa en la sospecha clínica y su confirmación con eco Doppler venoso de miembros inferiores. En el diagnóstico diferencial debe considerarse causas sistémicas de edema de miembros inferiores como la insuficiencia cardíaca, disfunción renal o hepática, y el uso de medicamentos hipertensivos. Otros diagnósticos diferenciales son linfedema, trombosis venosa subclínica, y dolor crónico de miembros inferiores. El tratamiento incluye la educación del paciente, medias de compresión, tratamiento médico y quirúrgico. En conclusión, la insuficiencia venosa crónica es una enfermedad frecuente y de mayor severidad en los pacientes de edad avanzada. La obesidad, la poca movilidad y las comorbilidades son los factores de riesgo asociados a la progresión de la enfermedad. La educación del paciente, el uso de medias de compresión y la terapia con flebotónicos son eficaces en el tratamiento. El tratamiento quirúrgico / endovenoso tiene buena efectividad en paciente de edad avanzada que padecen de IVC.

This research aimed to evaluate growth and hydrogen production from Rhodobacter capsulatus DSM155 and B10 strains in function of volatile fatty acids (VFA) media composition, as well as to assess the light intensity effect on hydrogen production. The growth of DSM155 and B10 was verified in media containing either acetic acid, butyric acid, or sodium lactate, or a mixture of them (ABL medium), being the ABL medium that produced the maximum cell dry weight, 2.15 and 1.67 g/L for DSM155 and B10, respectively. Biohydrogen production was evaluated in media containing acetic and butyric acids (AB medium), and ABL medium. Both strains presented the highest hydrogen production using ABL medium, being the highest 239.2 mL H2 for DSM155. Finally, light intensity (10, 20, and 30 klux) effect on biohydrogen production was studied using the best strain and medium, i.e., DSM155 and ABL medium. DSM155 produced hydrogen increasingly in the order 10, 20, and 30 klx (2753.5, 2850.5, and 2946.3 mL H2/Lop, respectively); however, the light conversion efficiency into hydrogen showed an inverse trend, 7.47, 4.16, and 2.67 %. In conclusion, R. capsulatus DSM155 is advisable for biohydrogen production using ABL medium in the range 10-30 klux. Moreover, further work is recommended on DSM 155 using organic acid-rich real effluents from dark fermentation.

Resistance to Immune Checkpoint Blockade (ICB) constitutes the current limiting factor for the optimal implementation of this novel therapy that otherwise demonstrates durable responses with acceptable toxicity scores. This limitation is exacerbated by a lack of robust biomarkers. In this study, we have dissected the basal TME composition at the gene expression and cellular levels that predict response to Nivolumab and prognosis. BCR, TCR and HLA profiling were employed for further characterization of the molecular variables associated with response. The findings were validated using a single-cell RNA-seq data of metastatic melanoma patients treated with ICB and by multispectral immunofluorescence. Finally, machine learning was employed to construct a prediction algorithm that was validated across eight metastatic melanoma cohorts treated with ICB. Using this strategy, we have unmasked a major role played by basal intratumoral plasma cells expressing high levels of IGKC in efficacy. IGKC, differentially expressed in good responders, was also identified within the Top response-related BCR clonotypes, together with IGK variants. These results were validated at gene, cellular and protein levels; CD138+ Plasma-like and Plasma cells were more abundant in good responders and correlated with the same RNA-seq defined fraction. Finally, we generated a 15-genes prediction model that outperformed the current reference score in eight ICB-treated metastatic melanoma cohorts. The evidenced major contribution of basal intratumoral IGKC and plasma cells in good response and outcome in ICB in metastatic melanoma is a groundbreaking finding in the field beyond the role of T lymphocytes.

Leucine-rich α-2 glycoprotein1 (LRG1) is a member of the leucine-rich repeat (LRR) family that was implicated in multiple diseases including cancer, aging and heart failure as well as diabetes and obesity. LRG1 plays a key role in diet-induced hepatosteatosis and insulin resistance by mediating the crosstalk between adipocytes and hepatocytes. LRG1 also promotes hepatosteatosis by upregulating de novo lipogenesis in the liver and suppressing fatty acid β oxidation. In this study, we investigated the association of LRG1 with obesity markers including leptin and other adipokines in adolescents (11-14 years; n=425). BMI-for-age classification based on WHO growth charts was used to define obesity. Plasma LRG1 was measured by ELISA while other markers were measured by multiplexing assay. Median (IQR) of LRG1 levels was higher in obese [30 (25, 38) µg/mL] and overweight [30 (24, 39) µg/mL] adolescents, compared to normal-weight participants [27 (22, 35) µg/mL]. The highest tertile of LRG1 had an OR [95%CI] of 2.55 [1.44, 4.53] for obesity. LRG1 was positively correlated to plasma levels of HsCRP (R=0.2), Leptin (R=0.2) and Chemerin (R=0.24) with p<0.001. Additionally, it was positively associated with plasma level of IL6 (R=0.17) and IL10 (R=0.14) but not TNF-α. In conclusion, LRG1 levels are increased in obese kids and associate with increased levels of adipogenic markers. These results suggest the usefulness of LRG1 as an early biomarker for obesity and its related pathologies in adolescents.

Published: July 2022

Alternative solutions in overcoming the waste problem are carried out by developing a waste bank which is a social engineering activity that teaches people to sort waste and raises public awareness in waste management. The eco-design innovation of waste processing with a digital-based waste bank program with a synergistic pentahelix approach has become an innovation at the grassroots level, especially in Sukoharjo. This study uses a qualitative method, which is equipped with data analysis with descriptive statistics. The effectiveness of waste management is defined by the high amount of managed waste, the amount of waste being recycled, and the large economic benefits resulting from waste management. This is due to the low percentage of managed waste and the low percentage of recycled waste, which of course also has low economic benefits. Waste banks in the Sukoharjo area need to be further involved in this waste management, so that the effectiveness of its management increases and the economic benefits taken can be maximized. The existence of a waste bank has proven to be effective in reducing waste problems in Sukoharjo. it is necessary to use digital technology which is still rarely used by waste banks in Sukoharjo. Therefore, an eco-design of waste management through a digital-based Waste Bank in Sukoharjo needs to be implemented. Eco-design of waste management through the Waste Bank in this study is to use Pentahelix synergy, namely collaboration between elements of government, academia, the business sector, community, and the media.
