Assessment of the effect of peat soil on the content of mobile forms of heavy metals and allelotoxicity in urbanized soils under moisture-loving plants at the Ecological Station of the Russian State Agrarian University – Moscow Timiryazev Agricultural Academy
Authors: Gvozd V. K. , Shalamov D. I. , Dzhancharov T. M.
Published: July 2024

The article presents the results of studies on the sorption of pollutants by moisture-loving plants when using peat soil under different anthropogenic loads. The comparative cultivation of moisture-loving plants on sod-podzolic soil, typical for this area, and on peat soil revealed their specificity in the sorption of heavy metals: there was a decrease in the content of lead and copper in peat soil under moisture-loving plants. In typical sod-podzolic soil under moisture-loving plants the opposite dynamics was observed. As for the zinc content, it was found that it increased in peat soil under moisture-loving plants, with the exception of reed. The experiment was conducted on the territory of the Ecological Station of the Russian State Agrarian University – Moscow Timiryazev Agricultural Academy in Moscow in 2019‑2022. Thus, moisture-loving plants grown on peat soil as a substrate can be used to reduce the content of mobile forms of heavy metals (lead and copper) in urbanized soils.

Published: July 2024

The article presents the data on the use of higher aquatic vegetation (HAV), such as naiads, as an alternative source of plant proteins in poultry feeding. The use of non-traditional raw materials contributes to the development of immunity in poultry without the need for antibiotics, which is relevant in the context of combating antibiotic resistance. The developed feed composition can not only significantly improve the quality of poultry feed, but also provide consumers with high quality and safe products. The results of the research can be promising for poultry feeding practice and contribute to the sustainable development of poultry farming.
Borys Grinchenko: poet, lyrical subject, and epoch
Authors: Levchyk Nadiia
Published: July 2024

The focus of the paper is on the complicated process of including Borys Grinchenko’s poetic heritage in the cultural history of the Ukrainian people as a nation. Attention is drawn to the erroneous statements in the studies of the 1930s to 1950s and the restoration of a fair assessment later. The paper traces the evolution of Borys Grinchenko’s poetry based on the analysis of particular details in his works and materials of discussion on the recognition of the literary value of his “poetic word”. The texts of his works are analysed as the case study the 1903 lifetime edition “Writings. Volume 1”, which was wrongly underestimated at the time.The innovative tendencies of his poetic thinking can be traced from the beginning of his literary activity to the last years of his life. Attention is drawn to the genres, themes, figurative language, and stylistic features of Grinchenko’s poetry in their evolutionary development (the 1880s through the 1900s). Particularly noteworthy is the rhythmic and melodic structure of the author’s poetry and its gradual changes. His works may be associated with such stylistic systems of Ukrainian poetry as Enlightenment romanticism, neo-romanticism, and symbolism. The edition of Borys Grinchenko’s poetry “Writings. Volume 1”, highly appreciated by Lesia Ukrainka at the time, may serve a code for understanding the peculiarities of his creative style as a poet. In addition to the epic mastery that distinguished the writer, his poetry demonstrated the expressive lyricism of the “poetic word”. One of the peculiarities of Grinchenko’s poetic pieces was cyclization, especially evident in the collection “Minutes”, which was included in the mentioned edition. In the author’s lyrical and confessional preface, he clearly outlines the image of the lyrical hero of his works. The lyrical character and his individual existence are extremely important for Grinchenko as the poet. The final part of the paper formulates the fundamental values of Borys Grinchenko’s life credo. His poetry has been and continues to be a significant and valuable cultural phenomenon, contributing effectively to the establishment of Ukraine as a nation.
The concept of "maximalism" in the literary studies of Yevhen Sverstyuk and Ivan Dziuba
Authors: Yurchenko Vadym
Published: July 2024

Subject of this article is the concept of “maximalism” in the critical works of the Sixtiers, particularly focusing on Yevhen Sverstiuk and Ivan Dziuba. So far, there have been no studies addressing the reception of maximalism by Sixtier critics or its place in their journalistic and scholarly discourse, making this investigation a pioneering effort and thus highly relevant. Furthermore, this article could lay the groundwork for further examination of Sixtier language within the framework of post-colonial theory, as it touches upon the issue of imperial influence on individual identity.

The aim of this research is to determine the frequency of the usage of the maximalism concept among Sixtier critics, evaluate its position and role within the ideological language of the empire, and discern any shifts in interpretation from established norms. The following conclusions have been drawn: 1. In the theoretical constructs of Sixtier critics, the concept of “maximalism” emerges as highly productive, consonant with the prevailing ideological discourse of the time. Several works of literary critics were dedicated to the issue of moral maximalism, with Ivan Dziuba employing the concept with notable frequency (appearing in roughly every fourth article within the trilogy “From the Well of Years”). 2. Sixtier critics were aware of the stereotypical nature of this concept and its frequent usage in contemporary periodicals and critical literature. They imbued it with their own nuanced meanings, which opposed the prevalent uncritical usage within Soviet public discourse. 3. Moreover, maximalism emerges as a fundamental aspect of the moral consciousness of the Sixtiers, embodying ideals of moral absolutism, particularly within Kantian philosophy. They emphasized the necessity of fostering individuals of high moral standing, primarily demanding of themselves, capable of self-sacrifice in the name of moral rectitude, civic duty, attention attention to the oppressed, and the belief in the intellectual’s ability to change the world. They vehemently opposed the ideas of moral relativism that were deemed unacceptable and antithetical to moral absolutism. There exists a distinct divergence in the declared sources of morality, with Ye. Sverstiuk emphasizing Christian sources, while Ivan Dziuba’s sources differ, leaning towards socio-philosophical sources.

This study can serve as a foundation for further research into moral issues in the works and criticism of the Sixtiers.
The limited scope of BPK audit and comparison with other supreme audit institutions
Authors: Putra Angga Kiryaditama , Sugimin Sugimin
Published: June 2024

The role of BPK is to audit state finance management and accountability in all entities that manage state finances freely and independently. However, the BPK's authority to conduct audits of state finances is debatable and limited when some laws and regulations are inconsistent. This study uses legal doctrinal and comparative legal research to explore improvements/harmonization of regulations and comparisons with SAI in other countries regarding the scope of audit that can be carried out to strengthen BPK's authority further. The results of this study indicate that there is still a conflict of norms regarding the scope of BPK's audit, as well as a conflict of interpretation of what it means to audit the management and accountability of state finances in Indonesia. Improving the legal instruments that regulate the scope of BPK audits can avoid conflicting norms and multiple interpretations of legal norms, allowing BPK's role to be more optimal in the future.

Şaman mitolojisinde eril ve dişil semboller
Authors: Öksüz Feyza
Published: June 2024

Mitolojik anlatılar, yazının öncesine dayanan ilk toplumlarda, o toplumun yaşadığı kültürü yansıtan, normlarını şekillendirmek üzere anlatılan, insanlığın dünyadaki var oluşunu kutsal alana atfederek anlatılan hikayelerdir. Mitolojinin ataerkil inanışına geçmeden önce anaerkil bir dünya görüşü ile başlanıldığı bilinmektedir. Bu nedenle şamanlığın din ya da inanç tartışmasından önce anaerkil bir kökene dayandığını söylemek mümkündür. Şamanizm, genellikle kadın ve erkek şamanların eşit şekilde aktif olduğu ve topluluk içinde önemli roller üstlendikleri bir geleneğe sahiptir. Bu nedenle, bazı araştırmacılar Şamanizm’in anaerkil kökenlere dayandığını öne sürmüşlerdir. Şamanizm, genellikle avcı-toplayıcı topluluklarda ortaya çıkmıştır ve bu topluluklarda kadınlar ve erkekler arasında daha eşitlikçi bir toplumsal düzenin olduğu düşünülmektedir. Kadınlar, avcı-toplayıcı topluluklarda genellikle toplumun hayatta kalması için hayati öneme sahip olan gıda toplama işine katkıda bulunmuşlardır. Şamanizmde, kadınlar şaman olarak görev yapmakta ve topluluk içinde önemli bir rol oynamaktadırlar. Kadın şamanlar, ruhsal rehberlik, şifa ve toplumsal dengeyi koruma gibi görevleri üstlenmişlerdir. Bu durum, Şamanizm’in kadınları toplumun ruhsal ve spritüel liderleri olarak gördüğü ve kadınların toplum içinde önemli bir güce sahip olduğu fikrini desteklemektedir. Şamanizm, birçok farklı kültürel ve coğrafi bağlama sahiptir ve farklı topluluklarda farklı biçimlerde gelişmiştir. Bazı topluluklarda kadınlar, şamanlık geleneğinde öndeyken bazılarında ise erkeklerin aha baskın olduğu gözlemlenebilmektedir. Şamanizmin kendini ifade etmee şekillerinden biri sembollerdir. Semboller, bir toplumun ruhsal ve manevi yaşamında önemli bir rol oynarlar. Din, inanç sistemleri ve spiritüel uygulamalar genellikle sembollerle doludur ve bu semboller, inançların ifadesi, ibadetlerin gerçekleştirilmesi ve manevi deneyimlerin yaşanması için kullanılır. Şamanizm, sembollere dayanır çünkü semboller, şamanlar için iletişim araçları, spiritüel rehberler ve ruhsal deneyimlerin ifadesi olarak işlev görür. Tam da bu nedenle Şaman Mitolojisi’nde Eril ve Dişil Semboller adlı çalışmamızda, şaman mitolojisinden yola çıkarak tarihsel süreçte şamanik ritüellerde kullanılan semboller ortaya konularak bu sembollerin eril ve dişil olarak bir karşılaştırması sunulacaktır.

Derechos humanos y de los animales, una relación de dignidad: El caso de México
Authors: Gómez Esquivel Claudia Ivette
Published: June 2024

La relación de las personas con la naturaleza ha estado presente desde el origen de la vida. Dentro de la naturaleza encontramos a los animales quienes han fungido diferentes papeles dentro de la humanidad, como alimento, vestido, fuerza de trabajo, religión, y como compañía. A nivel internacional existen cada vez más leyes que los protegen y velan por su dignidad; sin embargo, en países en desarrollo como México, aún prevalece una gran falta de conciencia hacia el trato digno de los animales. El objetivo general de este trabajo es mostrar la relación entre los derechos humanos y los de los animales, primero a nivel internacional y después en México, centrándose en la evolución de los derechos de los animales. Se hace una reflexión sobre el antropocentrismo del hombre, cuáles serían los beneficios de apartarse de este pensamiento y, cómo una visión biocéntrica de protección hacia todos los seres vivos mejora la calidad de vida de estos.

Published: June 2024

El objetivo principal del artículo consiste en presentar el estado actual del proyecto editorial Ellacuría: Obras completas. Para ello hemos realizado una reconstrucción de las diferentes etapas del proceso: 1) Registro y clasificación de los documentos, 2) transcripción y elaboración de la ficha técnica, 3) ordenación cronológica y composición de los volúmenes, y, por último, 4) edición crítica y composición de los volúmenes. 
Creemos que el trabajo realizado puede ayudar a trazar una imagen global de la heterogénea y fragmentaria obra de Ellacuría, así como algunas de sus principales dificultades: acceso muy restringido a una obra que ha tenido una circulación muy local, una gran cantidad de documentos inéditos, sin fechar o firmados bajo seudónimo, etc. Por todo ello consideramos necesario realizar la primera edición crítica de las obras completas de Ignacio Ellacuría, que facilite su acceso tanto a los especialistas como al gran público en general de uno de los autores más relevantes de la filosofía latinoamericana contemporánea.

Teleparallel Energy Density within the Framework of Rainbow Gravitation Theory for A Spatial Self-Similar, Local Rotational Symmetric Model
Authors: Korunur Sibel , Korunur Murat
Published: June 2024

It is known that the general theory of relativity provides valuable answers about our universe. General relativity theory is used to describe space, time, and mass-energy interactions, while quantum theory is used to explain the behavior and interactions of microscopic particles. The gap between these two theories reveals the need to develop a unified theory of "quantum gravity". However, so far no universal theory has yet been found that fully resolves this conflict. This is a big puzzle that physicists have been working on for a long time, and unifying these two theories harmoniously is one of the biggest challenges in modern physics. One of the theories put forward for this purpose is the "Rainbow" theory of gravity. In this study, Einstein, Bergmann-Thomson and Landau-Lifshitz energy densities are calculated for a spatial self-similar, locally rotationally symmetric model using teleparallel geometry within the framework of the Rainbow theory of gravity. However, the results obtained are evaluated using rainbow functions that are well known in the literature. The obtained results are rewritten as explicit forms of energy densities for Einstein, Bergman-Thomson and Landau-Liftshitz representations using f_1 (\chi)=1/(1-\chi)and f_2 (\chi)=1 rainbow functions. Accordingly, it has been shown that the test particle changes its energy density for the Einstein and Bergmann-Thomson energy-momentum prescriptions but does not change the energy density for the Landau-Liftshitz energy-momentum prescription.
Kırmızı Akar (Dermanyssus gallinae) ile On Yıl
Authors: Savaş Türker
Published: June 2024

Kırmızı akar (Dermanyssus gallinae) kanatlı hayvanlarda kan emen gececil bir parazittir. Birçok çalışma kanatlı sektörüne söz konusu parazitin ekonomik zararını göstermiştir. Bu derlemede yazar ve çalışma arkadaşlarının kırmızı akar ile yaptıkları çalışmaların bir değerlendirilmesi yapılmıştır. Çalışmalarda popülasyon dinamiğini takip edebilmek için akarın yuvalanmasını sağlayacak yapılar tasarlanmış; bunların yardımı ile özellikle akar yoğunluğu tahmin edilmiştir. Bir akarın canlı ağırlığının ortalama 55 µg olduğu ve bir gecede 203 µg kan emebildiği belirlenmiştir. Parazitin tavuk ve bıldırcınların büyümesini olumsuz etkilediği, büyümenin erken dönemindeki bir enfestasyonun eşeysel olgunluğu geciktirdiği ve yumurta verimi ile yumurta ağırlığını düşürdüğü belirlenmiştir. Tavuklarda büyümenin hibrit genotiplerde akardan benzer şekilde etkilendiği, ancak saf genotiplerde farklılaşabildiği gözlenmiştir. Konakçının beslenmesinin akarın etkilerine nasıl yansıdığı konusunda çalışma bulunmamasına karşın, yem tüketiminin muhtemelen düşük akar yoğunluğunda arttığı, yüksek akar yoğunluğunda ise azalabileceği ortaya konmuştur. Yoğun akar enfestasyonunda (25.000 akar/kg) mortalitenin arttığı, parazit yoğunluğundaki her bir 1000 akar artışının bir kuşun (yaklaşık 100g canlı ağırlığında) ölüm riskine %11 arttırdığı bulunmuştur. Enfestasyon altındaki hayvanlarda konfor davranışı sayılamayacak sıklıktaki kaşınma ile lokomosyon artışının ek bir enerji kaybına neden olabileceği; yanı sıra akarın kuşun derisi üzerinde gezinmesi ve ısırıkları nedeniyle oluşan stresin de hayvanların refahını önemli ölçüde olumsuz olarak etkileyebilmesi olasıdır.

Abstract. The optimized geometry of methyl 2-oxo-1,2-dihydrofuro[3,4-d] pyrimidine-3(4H) carboxylate (FP) was determined by density functional theory calculations. Geometric properties of FP such as bond length, bond angle, dihedral bond angle, and HOMO-LUMO energies in the gas phase were calculated by using the Gaussian program. Delocalization of the molecule’s charge was analyzed using Mulliken Population Analysis (MPA) and Natural Population Analysis (NPA) approaches.  Electrophilic and nucleophilic regions of FP were identified by drawing a molecular electrostatic potential map. NMR and FTIR spectra were calculated with the B3LYP and 6-311++G (2d, p) basis set and a detailed FTIR analysis was performed by using the VEDA program. To determine the consistency of the calculated NMR and FTIR spectra, they were compared with their corresponding experimental NMR and FTIR spectra. Molecular insertion studies of FP with six different cancer proteins were analyzed and their interactions were evaluated. Data on the pharmacokinetics and drug affinity of FP were obtained through the Swiss ADME and ADMET programs.

Abstract. Solid biomass fuels are economical and practical renewable energy sources. Exploitation of agricultural biomass as a fuel offers considerable advantages in different domains as energy supply as far as the climate is involved. In this study we intended to investigate the feasibility of alternative agricultural residues of grape pomace and corn cob pellets with addition of sawdust, starch, and waste rapeseed oil and to examine how these additives affects the calorific powers and pellets physical properties. Sawdust, starch, and waste rapeseed oil addition was 10 %. Pellets were produced by a manual single pellet press. The calorific powers of the biomass samples were experimentally determined using an oxygen bomb calorimeter (model 6200 adiabatic calorimeter Parr Instruments). The results show that waste rapeseed oil addition significantly increases the calorific powers in grape pomace and corn cob pellets. The highest calorific value was obtained for the grape pomace pellets containing 10 % waste rapeseed oil, 22.14 MJ/kg, compared to grape pomace control pellets, of 21.35 MJ/kg. The calorific values of corn cob control pellets were also increased when adding 10 % waste rapeseed oil, from 17.29 MJ/kg to 19.76 MJ/kg.
The results obtained in this work, related to calorific powers, moisture, ash, volatile, sulphur and nitrogen content, fixed carbon, bulk density, fuel value index, energy density and combustion efficiency, revealed that depending on additives used and their dosage, an acceptable fuel pellet could be produced.

Male reproductive health is intricately regulated by molecular and physiological processes, with the aryl hydrocarbon receptor (AhR) playing a crucial role. AhR is activated by various ligands and influences the onset and progression of diseases. The aim of this study was to evaluate the role of AhR on spermatogenesis in adult male rats were affected by resveratrol (RES) and CH223191, an AhR antagonist. The study include forty rats were randomly divided into four equal groups: Control group, DMSO group, RES group and AhR‾ group, the rats received respective treatments intraperitoneally twice weekly for 60 days, and various parameters related to male reproductive health were evaluated. The AhR that activation by the RES treatment were enhanced the sperm morphology, sperm acrosomal integrity and luteinizing hormone. Moreover, the Dnah1 gene expression, is has play major role in sperm morphology, was upregulated and testosterone levels were elevated by RES. On the other hand, sperm morphology, sperm acrosomal integrity, testosterone hormone levels, and Dnah1 expression were all reduced in AhR‍ rats. The testicular tissue integrity was maintained by RES, according to a histopathological analysis. These findings highlight the role of AhR in male reproductive health and suggest RES as a potential therapeutic agent.

Published: June 2024

The study aimed to assess the effects of different concentrations of Ziziphus spina-Christi (ZSC) leaves on the fertility of buck goats. Twelve buck goats aged 12–15 months with an average body weight of 22±2 kg were divided randomly into three dietary treatments: T1, T2, and T3, each given a basal diet daily plus feeds of 20 g/kg (2%) of ZSC for T1 and 40 g/kg (4%) of ZSC for ‎T2; and T3 was used as the control that consumed a basal diet only. The experiment lasted for 3 months. On days 45 and 90, blood samples were collected for plasma testosterone measurement using an immunochromatographic assay. Additionally, semen samples were collected at the same time points for physical (volume, color, and pH) and microscopic (semen concentration, mass and individual motility percentage, and live-dead sperm percentages) evaluations. ‎ The results showed that ZSC at 4% significantly (P<0.05) increased the testosterone hormone concentration and all physical parameters at 45 and 90 days comparing to 2% ZSC and control ‎groups. ‎Additionally, ZSC at 4% significantly improved (P<0.05) the microscopic parameters at both ‎time periods compared to 2% ZSC and control groups. The present findings revealed that ZSC at 4% diet could enhance goat semen processing and ‎goat fertility enhanced significantly (P<0.05) the testosterone hormone that had higher values ‎compared to ‎‎(2%) of the ZSC control group. Similarly, (4%) of ZSC affected the physical ‎assessment of ‎semen, such as the volume, color, and pH values. Thus, adding ZSC with a high ‎concentration ‎‎(4%) could enhance goat semen processing and goat fertility in general.
