Political Thought of Russia’s Allies in Poland in 1920: An Intellectual History of B.V. Savinkov Group
Authors: Popov F. A.
Published: February 2025

This article reconstructs the political thought of the Russian anti-Bolshevik emigration in Poland during the Polish-Soviet War and the subsequent peace negotiations. The primary sources include materials from the Warsaw newspaper “Svoboda,” published by the Russian Political Committee (RPK) led by B.V. Savinkov. It emphasizes that, operating on foreign soil, émigrés laid the ideological groundwork for Russian-Polish cooperation. The article notes that Polish authorities harbored distrust towards the White movement, perceiving it as a potentially hostile force against Poland. It demonstrates that the RPK sought to dispel these suspicions by openly declaring a pro-Polish stance, which, in turn, provoked irritation among the right wing of Russian society (monarchists and supporters of “United and Indivisible Russia”). The author concludes that B.V. Savinkov, during the Civil War years, adopted a nationalist discourse, reflecting the influence of Józef Piłsudski — a socialist, revolutionary, and nationalist. The question of an independent Poland as a source of inspiration for democratic émigrés, who hoped for a similar awakening of Russian national consciousness, is also raised. The relevance of this study lies in the necessity to explore the Civil War within the context of intellectual history.
The right to the ecological city: Reconciling ecological sustainability and social justice in a neighbourhood transformation in Turin
Authors: Krähmer Karl
Published: February 2025

Cities have gained increasing attention in the debate on how to tackle the global environmental crisis. However, urban strategies for sustainability have often been criticised for being insufficient in effectively mitigating environmental impacts due to externalisation and cost-shifting, and for producing social contradictions, such as ecological gentrification. Rather than considering these critiques as reasons to abandon ecological urban transformations, this article advocates for the right to the ecological city, for which the goals of ecological sustainability and social justice need to be reconciled through a degrowth strategy based on the principles of sufficiency, reuse and sharing. However, this theoretical framework encounters several challenges in urban practice. These are discussed through the author’s lens as an observant participant in the Fondazione di Comunità Porta Palazzo, a community foundation involved in the transformation of the neighbourhoods of Aurora and Porta Palazzo in Turin, Italy, through projects focused on public space and housing. The discussion of these challenges suggests that while the right to the ecological city is hard to achieve, it remains an important goal in the transformation of cities and neighbourhoods, one that must rely on structural change driven by diverse actors across multiple scales.
Domesticating neoliberal foodscapes: An everyday approach to understanding food system transitions in Oaxaca, Mexico
Authors: Ismail Aisha
Published: February 2025

The persistence of neoliberal food systems has often been explained with reference to political economy dynamics or the market and political activities of agri-food companies. This article approaches the issue from a different level of analysis and asks: how do the everyday lives of people sustain neoliberal foodscapes? The article utilizes an Everyday Political Economy approach, combined with Smith and Rochovská's (2007) concept of 'domesticating neoliberalism', and applies this to the study of the sale of ultra-processed foods by small corner shops (tiendas) in the southern Mexican city of Oaxaca de Juárez. The article argues that tienda owners respond to the increasing power of UPF corporations by maintaining neoliberal foodscapes as they seek to support themselves in challenging socio-economic circumstances. This perspective is important in advancing thinking for solutions to transition away from commodified, profit-orientated and ecologically destructive food systems because it situates the everyday as the site for intervention and calls attention to the broader material conditions of people's lives as they are forced to 'make do' within neoliberal worlds.

Published: February 2025

This study investigated the adsorption and desorption performances of water hyacinth leaves powder (WHLP) and water hyacinth roots powder (WHRP) towards Pb2+, Co2+, Zn2+ and Ni2+ in industrial wastewater. The parameters influencing the process were assessed, models were proposed to explain the both the equilibrium and kinetics of the sorption process and desorption study was conducted using different HNO3 and NaOH concentration. The results showed that comparatively, the metal uptake capacity of water WHLP was higher than WHRP as examined by the investigated parameters. The biosorption data fitted to both Langmuir and Freundlich isotherms. The kinetics of the process follows a pseudo-second order reaction model because it provides good linearization of the experimental data. In addition, relatively successful metal ions desorption from the biosorbents were recorded with both NaOH and HNO3 solutions.
Indole-3-propionic acid reduces lipid peroxidation induced by potassium iodate in porcine thyroid
Authors: Iwan Paulina , Karbownik-Lewinska Malgorzata
Published: February 2025

Iodine is a trace element indispensable for thyroid hormone biosynthesis but its deficiency is a global problem. Programs of iodine prophylaxis are frequently based on salt iodization with the use of potassium iodate (KIO3), which, however, reveals potential prooxi-dative properties. Indole-3-propionic acid (IPA), deamination product of tryptophan, is an effective antioxidant without prooxidative properties. We have shown in our previous study that melatonin is able to reduce lipid peroxidation caused by KIO3. Taking into account the similarity between melatonin and IPA we decided to evaluate potential protective effects of this compound against KIO3-induced lipid peroxidation in porcine thyroid homogenates. In the current study thyroid homogenates were incubated in the presence of different concentrations of KIO3 without/with IPA. Six experiments were performed with different concentrations of IPA. Malondialdehyde+4-hydroxyalkenals (MDA+4-HDA) concentration (LPO index) was measured spectrophotometrically. IPA reduced in concentration-dependent manner (with statistical significance for concentrations of 10 mM, 7.5 mM, 5.0 mM) KIO3-induced lipid peroxidation, but only when KIO3 was used in concentrations of 10 mM and 7.5 mM, which are close to physiological iodine concentration in the thyroid (i.e. ~10 mM). In conclusion, IPA might be considered as a pharmacological agent to be used for protection against prooxidative effects of iodates.
Osmotic fragility during in vitro erythrocyte cytotoxicity induced by aluminium chloride, lead acetate or mercuric chloride in hyposmolar sucrose media
Authors: Igbokwe Nanacha Afifi , Igbokwe Ikechukwu Onyebuchi
Published: February 2025

Erythrocyte death by eryptosis or erythronecrosis may induce erythrocyte shrinking or swelling with increase in osmotic resistance or fragility as indication of cytotoxicity. We investigated heterogeneous cytotoxic outcomes during in vitro exposure of goat erythrocytes to aluminium chloride, lead acetate or mercuric chloride using erythrocyte osmotic fragility (EOF) testing. The metallic salt solution (MSS) was added to 4.0 μL of high (100 mosmol/L) and low (250 mosmol/L) hyposmolar sucrose media at 0.3 or 0.4 mosmol/L concentration during testing of the osmotic fragility of 5.0 μL of blood from 10 goats. Hemolysis induced in the media (with and without MSS) was estimated in the supernatant with spectrophotometer at 540 nm. Osmotic stabilization or destabilization was calculated with probability for each test. Inducible osmotic resistance (IOR) was the ratio of mean stabilization to destabilization in both high and low hyposmolar media. Each MSS induced both osmotic resistance (stabilization) and fragility (destabilization) in varied media concentrations, with greater likelihood (P) of stabilization (0.93) or destabilization (0.77) in high or low media hyposmolarity, respectively. The EOF outcomes of the goats diverged within the group. High IOR induced by mercuric chloride (2.90) and low IOR by lead acetate (0.07) and aluminium chloride (0.04) reflected high stabilizing and destabilizing outcomes, respectively. In conclusion, MSS induced dual EOF outcomes (stabilization or destabilization) on the fragility domain, suggesting occurrence of both eryptosis (as stabilization) and erythronecrosis (as destabilization) at low exposure level, whereby biphasic, nonmonotonic or hormetic response to MSS toxic action might exist.
Cardioprotective effect of citicoline against arsenic trioxide-induced injury in H9C2 cell line
Authors: Fallah Fahimeh , Aminzadeh Azadeh
Published: February 2025

Cardiotoxicity is one of the most serious adverse effects of exposure to arsenic. It has been shown that cytidine 5′-diphosphocholine or citicoline exerts a variety of biological functions, including anti-inflammatory and antioxidant activities. The aim of current study was to investigate the effect of citicoline on arsenic trioxide (ATO)-induced cardiotoxicity in H9C2 cells. H9C2 cardiac cells exposed to ATO for 24 h to induce cytotoxicity. The cells were pre-incubated with citicoline for 72 h prior to the exposure to ATO. The effect of citicoline on cell viability was investigated by MTT method. Malondialdehyde (MDA), total thiol groups, and total antioxidant power (TAP) levels were also evaluated. The results indicated that citicoline could effectively enhanced cell viability of H9C2 cells exposed to ATO. Treatment with ATO increased MDA levels, while pretreatment with citicoline reduced lipid peroxidation. Moreover, it could enhance total thiol contents and TAP levels. Taken together, our data suggest that citicoline has protective effects against ATO-induced oxidative stress in H9C2 cells, that could be attributed to inhibition of oxidative stress and its antioxidant effects.

Published: February 2025

This article is devoted to the study of the representation of British Prime Minister Rishi Sunak, namely the connotative vector of perception of this image set by English news publications. The purpose of the research is to study the image of this politician formed in the English-language media with the help of political cartoons and to evaluate the direction of the transmitted ideas. The methods used in the study: description, comparison, content analysis, cognitive-discourse analysis. The practical material includes 152 political cartoons selected by continuous sampling and divided into two groups — those released before October 25, 2022 (taking office) and those after this date. Common to both groups are the metaphorical images of “rich man”, “debtor”, and “shield”. The typical images identified only in the first group are “magician”, and in the second — “attacked by monsters”, “killer”, “mathematician”. It is noteworthy that the connotative vector of Rishi Sunak’s representation is predominantly negative. Thus, a politician is most often depicted with exaggerated facial features (nose, chin, ears, etc.), facial expression (angry, arrogant, smug, etc.) and, at the same time, the cognitive antithesis “big — small” is applied to him which makes Rishi Sunak seem insignificant compared to other objects.

ABSTRAK
             Korosi merupakan fenomena alam yang dapat merusak material logam seperti baja St-37 dan juga menyebabkan degradasi struktur serta penurunan kinerja material logam. Beberapa penelitian telah dilakukan untuk mengembangkan inhibitor korosi sebagai solusi yang efektif. Salah satu bahan alam yang digunakan sebagai inhibitor korosi adalah ekstrak daun lemon, yaitu senyawa kimia yang ditambahkan ke lingkungan korosif untuk menghambat atau mencegah reaksi oksidasi logam. Penelitian ini bertujuan untuk mengetahui laju korosi baja St-37 dalam media korosif NaCl dan HCl serta efisiensi inhibisi penggunaan inhibitor ekstrak daun lemon dengan berbagai konsentrasi untuk mencegah korosi. Daun lemon diekstraksi menggunakan metode maserasi, kemudian ekstrak tersebut diuji kandungan metabolit sekundernya. Laju korosi ditentukan menggunakan metode kehilangan berat. Hasil uji fitokimia menunjukkan bahwa ekstrak daun lemon positif mengandung alkaloid, fenol, flavonoid, tanin, dan tanin terkondensasi. Laju korosi terendah baja St-37 pada media korosif NaCl dan HCl masing-masing sebesar 0,1685 dan 0,0658 mmpy (millimetre per year), dan efisiensi inhibibisi tertinggi untuk melindungi media korosif masing-masing sebesar 96,6963 dan 40,3065%, dicapai pada konsentrasi inhibitor 500 ppm. Pengurangan laju korosi dan efisiensi penghambatan oleh ekstrak daun lemon pada baja S-37 dalam media korosif HCl lebih baik daripada dalam media NaCl.

ABSTRACT
         Corrosion is a natural phenomenon that can damage metal materials such as St-37 steel and also causes structural degradation and decreased performance of metal materials. Several studies have been conducted to develop corrosion inhibitors as an effective solution. One of the natural products used as a corrosion inhibitor is lemon leaf extract, a chemical compound added to corrosive environments to inhibit or prevent metal oxidation reactions. This study aimed to determine the corrosion rate of St-37 steel in NaCl and HCl corrosive media and the inhibition efficiency of using lemon leaf extract inhibitors with varying concentrations to prevent corrosion. Lemon leaves were extracted using the maceration method, and then the extract was tested for secondary metabolite content. The corrosion rate was determined using the weight loss method. The results of the phytochemical test showed that lemon leaf extract positively contained alkaloids, phenols, flavonoids, tannins, and condensed tannins. The lowest corrosion rate of the St-37 steel in the NaCl and HCl corrosive media of 0.1685 and 0.0658 mmpy (millimeter per year), respectively, and the highest efficiency of the inhibitor to protect corrosive media of 96.6963 and 40.3065%, respectively, were achieved at the inhibitor concentration of 500 ppm. The corrosion rate reduction and the inhibition efficiency by lemon leaf extract on the S-37 steel in HCl corrosive media was better than in NaCl media.

Experimenting with Sensorimotor Play to Enhance Learning Attention and Cognitive Function in Children at TK SPNF SKB Denpasar
Authors: Ratini Ni Kadek , Narta Dewi Anak Ayu Nyoman Trisna , Nugraha Made Hendra Satria , Utama Anak Agung Gede Eka Septian
Published: February 2025

Introduction: Children need attention and education from their families, schools, and communities to support their development. Cognitive function, especially attention, is vital for their learning process. Previous studies have shown suboptimal cognitive function (average digit span test score of 4.31) and decreased attention during lessons, evidenced by frequent seat changes and talking. Enhancing these areas through sensorimotor play can create more engaging and enjoyable learning experiences for children.
Methods: This quasi-experimental study utilized consecutive sampling to determine a sample size of 30 children based on Pocock's formula. Two classes from TK SPNF SKB were randomly selected, and subjects were assessed for eligibility based on inclusion and exclusion criteria. The subjects were randomly divided into 15 children in the intervention group and 15 in the control group. The intervention group participated in sensorimotor play sessions three times a week for three weeks, totaling nine sessions, each lasting 30-35 minutes. The control group did not receive any intervention.
Results: Data analysis using paired sample t-tests demonstrated a significant improvement in the intervention group's learning attention (p = 0.001) and cognitive function (p = 0.001). Independent t-test results indicated an essential difference between the two groups post-intervention (p = 0.001).
Conclusion: Sensorimotor play effectively enhances attention and cognitive function in children.

Published: February 2025

Foot-and-Mouth Disease (FMD), caused by the Foot-and-Mouth Disease Virus (FMDV), is a highly contagious acute infection affecting cloven-hoofed animals. In Lamongan Regency, outbreaks of PMK in cattle have led to a decline in population. Despite vaccination programs, farmers’ willingness to vaccinate is influenced by perceptions of vaccine safety and effectiveness. Increasing vaccination coverage is hoped to restore PMK-free status in the area. This research aims to understand the influence of farmers’ perceptions on government policies regarding PMK vaccination in cattle in Tikung District, Lamongan Regency, and to identify factors affecting these perceptions. The study employs a mixed-methods approach with a sequential explakomuninatory design. Data collection instrumen

ts include questionnaires and interview guidelines, utilizing both survey distribution and in-depth interviews with informants. Quantitative data analysis involves univariate and bivariate analyses, while qualitative analysis uses an interactive model. Research findings indicate a significant positive influence of farmers’ perceptions on PMK vaccination policies in Tikung District, Lamongan Regency (significance value of 0.000 (0.000 < 0.05) and t value of 5.894 > t table (1.9858)). Factors such as extensive knowledge of PMK and vaccination programs, personal expe- rience with the disease, and support from the government and livestock groups contribute to positive perceptions of these policies. However, challenges such as concerns about post-vaccination side effects and timing conflicts with farmers’ village activities affect participation rates and trust in the program.

Rando- mized block design consisting of four feeding treatments: Forage (T0), Forage+Soybean Husk Silage (SHS) (T1), Fo- rage+Brewer’s Spent Grain Silage (BSGS) (T2), and Forage+Odot Silage (OS) (T3), and three groups of bodyweights of goats. Variables observed were FAMACHA© score, endo-parasites, and erythrocytes level. The results, the goats were infected by Haemonchus spp., Eimeria spp., Trichostrongylus spp., and Ostertagia that dropped erythrocyte level below the standard 1.9 ± 0.39 (106 /?L). T3 goats tended to be infected by more endoparasites 906.7 ± 0.491 EPG with moderate infection, FAMACHA© score tended to be higher 1.5 ± 0.18, also tended to have lower erythroc- yte level 1,0 ± 0,39 (106 /?L). Contrastly, T1 goats tended to be infected by lesser endoparasite 200.0 ± 0.491 EPG. This proved that feeding SHS enabled T1 goats consuming the highest quantity and quality nutrient containing 0.34 kg crude protein, 4.64 kg TDN, with 0.06 kg kcal. In summary, feeding SHS improved health status of the goats by showing their FAMACHA© score, endoparasite, and erythrocyte level.

This research analyzes the performance of the Okumura-Hata propagation model in designing terrestrial link antennas for digital television transmitters at Tower Turyapada,Pegayaman Village, Buleleng. The findings are important for optimizing signal quality in regionswith geographical challenges, such as mountains and valleys, which obstruct signal propagation.The primary focus of the study is to measure and compare signal field strength at four test pointsin North Bali using simulations to predict the performance of the propagation model under differenttopographical conditions. The simulation results are then compared with theoretical calculationsto assess the model's accuracy and evaluate their alignment with established reference values.The results show that the Okumura-Hata model is not suitable and does not fully reflect thecomplex topography of Buleleng, as the simulation results were lower than the reference values.The study recommends using an alternative propagation model more suited to local geographicalconditions, along with more detailed field measurements to ensure optimal signal qualitythroughout the coverage area.

Published: February 2025

Subject. This article deals with the issues of evaluating misstatements identified in the course of applying statistical sampling procedures, based on the requirements of International Standards on Auditing.
Objectives. The article aims to substantiate the choice of the technique of processing the results of checking the elements of statistical sampling.
Methods. For the study, we used analysis and synthesis.
Results. The article proposes a point-estimation technique to predict the most likely misstatement in the general population, based on the position of mathematical statistics on the assessment of the general average for the sample mean, as well as the author-developed methodology for assessing the risk of sampling, based on solving the problem inverse to the problem of constructing a confidence interval, taking into account the influence of risk not related to the risk of sampling.
Relevance. The theoretical significance of the developed techniques lies in the development of the provisions of the International Standards on Auditing (International Standard on Auditing (ISA) 450 – Evaluation of Misstatements Identified during the Audit and International Standard on Auditing (ISA) 530 – Audit Sampling). The practical significance lies in the possibility of using the proposed techniques by auditors and audit firms in the implementation of statistical sampling procedures.
