Published: December 2024

The Eger Rift subsurface is characterized by frequent seismic activity and consistently high CO2 concentrations, making it a unique deep biosphere ecosystem and a suitable site to study the interactions between volcanism, tectonics, and microbiological activity. Pulses of geogenic H2 during earthquakes may provide substrates for methanogenic and chemolithoautotrophic processes, but very little is currently known about the role of subsurface microorganisms and their cellular processes in this type of environment. To assess the impact of geologic activity on microbial life, we analyzed the geological, geochemical, and microbiological composition of rock and sediment samples from a 238 m deep drill core, running across six lithostratigraphic zones. We evaluated the diversity and distribution of bacterial and archaeal communities. Our investigation revealed a distinct low-biomass community, with a surprisingly diverse archaeal population, providing strong support that methanogenic archaea reside in the Eger subsurface. Geochemical analysis demonstrated that ion concentrations (mostly sodium and sulfate) were highest in sediments from 50 to 100 m depth and in weathered rock below 200 m, indicating an elevated potential for ion solution in these areas. Microbial communities were dominated by common soil and water bacteria. Together with the occurrence of freshwater cyanobacteria at specific depths, these observations emphasize the heterogenous character of the sediments and are indicators for vertical groundwater movement across the Eger Rift subsurface. Our investigations also found evidence for anaerobic, autotrophic, and acidophilic communities in Eger Rift sediments, as sulfur-cycling taxa like Thiohalophilus and Desulfosporosinus were specifically enriched at depths below 100 m. The detection of methanogenic, halophilic, and ammonia-oxidizing archaeal populations demonstrate that the unique features of the Eger Rift subsurface environment provide the foundation for diverse types of microbial life, including the microbial utilization of geologically derived CO2 and, when available, H2, as a primary energy source.

Published: December 2024

The emergence of radio frequency identification (RFID) technology in the era of the Internet of Things represents a remarkable advancement, but also brings its own set of challenges. Low-cost RFID tags, key elements of this ecosystem, face major security and privacy issues due to their limited computational and memory capacities. To overcome these issues, we focused on the design of an ultralightweight RFID authentication protocol named UDAP, which incorporates simplified cryptographic techniques such as dot product, XOR, and left rotation. This approach aims to enhance the levels of security and confidentiality while concurrently minimizing the impact on the tag’s limited resources. Both informal and formal analysis of our protocol, including the use of the Scyther simulation tool, has demonstrated its effectiveness in countering the most known security attacks. To measure the efficiency of our proposed protocol, an Field-Programmable Gate Array (FPGA) implementation was carried out, allowing for precise evaluation of the resource consumption of the key function used in our protocol. This implementation has shown that our protocol is not only secure but also utilizes minimal resource consumption, making it particularly suitable for resource constrained RFID tags.

Published: December 2024

The aim of the research was to study the effect of silicon-containing organomineral fertilizer (OMF) on the quantitative and qualitative characteristics of spring wheat of the Yoldyz variety and buckwheat of the Nikolskaya variety, as well as the main agrochemical parameters of gray forest soil. The work was carried out in a pot experiment, the scheme of which involved the study of the following options: without fertilizers (control); N60P60K60 - background; OMF 2 t/ha; OMF 3 t/ha; background + OMF 2 t/ha; background + OMF 3 t/ha./ha. OMF was obtained by mixing heat-treated organic (chicken manure) at a temperature of 60...70°C and mineral (zeolite from the Tatarsko-Shatrashansky deposit of the Republic of Tatarstan) components in a ratio of 1:1. Soil and plant samples were analyzed using conventional methods. Agrochemical characteristics of the soil before the experiment: gray forest medium loamy soil with an organic matter content of 2.9%, pHKCl of 5.86 units, hydrolytic acidity of 2.16 mg/100 g, the sum of absorbed bases of 20.2 mg/100 g, the content of alkaline hydrolyzable nitrogen is 77.0 mg/kg, mobile phosphorus and potassium - 238.0 and 180 mg/kg accordingly. Under the influence of OMF, the agrochemical properties of the soil under wheat and buckwheat crops are improved: the indicators of metabolic and hydrolytic acidity decrease by 0.03...0.20 mg-eq./100 g, the amount of absorbed bases increases to 22.0...22.6 mg-eq./100 g, and the content of macronutrients increases. The use of OMF in doses of 2 and 3 t/ha both separately and in combination with mineral fertilizers improves the crop structure and increases the yield and quality of wheat grain: plant height increases by 5.7...15.8 cm, ear length - by 0.8...2.6 cm, biomass - by 5.5...9.5 g, grain yield - by 0.9...3.5 g/l compared to the control. The protein content increases by 7.03...8.38%. An improvement in buckwheat indicators has been established under the influence of OMF and mineral fertilizers relative to control values - plant height increases by 1.1...14.8 cm, biomass - by 1.0...11.3 g, yield - by 0.3...2.5 g/l. The protein content in buckwheat grain increases by 0.21...1.18%.

Published: December 2024

Bu makalede Nussbaum’un yapabilirlikler yaklaşımının hayata geçirilmesinde Çocuklar için Felsefe (ÇİF) uygulamasının önemi gösterilmeye çalışılacaktır. İnsanın doğuştan itibaren kendisinde bulunan merak ve hayret duygusunun yetişkinliğe doğru yitirildiği ve bilgi aktarımından öteye gitmeyen bir eğitimin demokratik bir yurttaş ortaya çıkmasında yetersiz kalmaktadır. Doğası gereği bilme eğiliminde olan insan, bu merakını bırakarak, olanı olduğu gibi kabul etmekte olup eleştirel bir bakış açısında sahip olmayı bırakmaktadır. Çocukluktan itibaren gerçekleşen felsefeyle ve refleksif düşünmeyle tanışma bu merakı canlı tutacaktır. ÇİF ve dolayısıyla felsefi bir düşünüşe sahip olma olumlu anlamda toplumsal dönüşümün önemli bir parçasıdır. Bireylerin eleştirel bakabilme, empati, akılcı karar verebilme, tüm canlılarla bağ kurabilme gibi pek çok açıdan gelişmesini sağlar. Bu yüzden ÇİF Nussbaum’un yaklaşımını açıklarken sıraladığı on maddeli merkezi yapabilirliklerden altısının aktüel hâle dönüşümünde kilit bir rol oynamaktadır. Bu makalede de öncelikle eğitimin ne olduğu ele alınarak, günümüz eğitim sistemindeki temel problemlere odaklanılacaktır. Merak, hayret, düşünme ve refleksif düşünme çerçevesinde çocukluktan yetişkinliğe ne türden bir değişim olduğu ve ÇİF uygulamalarıyla neler yapılabileceği ele alınacaktır. Sonrasında Nussbaum’un yapabilirlikler yaklaşımı, ÇİF eğitiminin bu yaklaşım ile olan ilişkisi ve bireylerin potansiyellerinin bu uygulamayla ne şekilde hayata geçirilebileceği üzerinde durulacaktır. Son kısımda ise ÇİF’in öğretmen/eğitmen, çocuk ve ebeveyn/bakım veren olan üç saç ayağı kritik edilerek yapabilirlikler yaklaşımıyla olan bağlantısı, bu yaklaşımdaki altı maddenin hayata geçirilmesinde eğitimin ve dolayısıyla ÇİF’in önemine vurgu yapılacaktır.

Published: December 2024

Hristiyanlık MS. 1 yüzyılda ortaya çıkmasıyla özellikle kadın ve köleler arasında büyük kabul görmüş ve ilerleyen yüzyıllarda da giderek yaygınlaşmıştır. Zaman içinde hristiyanlığın, bazı ruhban sınıfı tarafından değişik şekilde yorumlanması değişik tarikatların ortaya çıkmasına neden olmuş ve Hristiyan dünyasında ayrılıklar oluşmaya başlamıştır. Anadolu’nun da değişik bölgelerinde varlık gösteren bu mezhepler uzun bir süre varlıklarını devam ettirmişlerdir. Yerel otoritenin desteklediği din adamları tarafından ortaya çıkan bu mezhepler hoş karşılanmamış, düzenlenen konsillerde bu sapkın gruplar hakkında tartışılmıştır. Bu mezheplerden biri olan Athinganoi’dur. Mezhepten ilk olarak MS. 6-7. yüzyılda yaşamış Constantinoupolis’in presbyteros’u Timotheos bahsetmiştir. Daha sonra 8. Yüzyılda patricus Germanos ve MS. 8-9 yüzyılda yaşamış keşiş Theophanes de bu mezhepten söz etmektedir. I. Mikhael Dönemi’nde (MS. 811-813) mezhebin üyeleri idam edilmiştir. I. Mikhael yapılan bu zulüm ılımlı din adamlarının araya girmesiyle durdurulmuştur. II. Mikhael Dönemi’nde tarikat üzerindeki baskı ortadan kalkmıştır. MS. 10. Yüzyıldan MS. 14 yüzyıla kadar Bizans kaynaklarında mezhepten bahsedilmektedir. Bu makalede tarihsel süreç içinde Athinganoi mezhebi incelenmiştir

Authors: Sümer Mustafa Doğacan
Published: December 2024

Başar Sabuncu yazar, yönetmen ve çevirmen olarak Türk tiyatrosunda önemli bir yere sahiptir. Sabuncu’nun tiyatro eserlerinin temel özelliklerinden biri oyun hikayesini ve karakterleri sınıf ilişkileri merkezinde inşa etmesidir. Oyunlarında emeği sömürülen işçilerin eylemleri ve etkileşim biçimleri gerçekçi biçimde sahneye aktarılır. Bu sebeple Sabuncu işçilerin Türk tiyatrosundaki kalemlerinden biridir. İşçi sınıfı temsilinin tiyatroya yansımasına bakıldığında oyunları başvuru kaynakları arasında yerini alır. Sosyal bilimler ve tiyatro arasındaki temasın arttırılması, belirli temalar, dönemler üzerinden Türk tiyatrosuna yönelik araştırmalar yapılması, iki alan arasındaki bağın kuvvetlendirilmesi ve literatürün gelişimi açısından önemlidir. Bu savunudan hareket eden bu çalışmada Sabuncu’nun tiyatro eserlerinde işçi sınıfının nasıl temsil edildiğine odaklanılacaktır. Toplumsal hiyerarşinin en alt basamadığında yer alan işçi karakterlerin hangi düşünce ve davranış pratiklerine sahip olduğuna ve gündelik yaşamlarının yazar tarafından nasıl kurgulandığına yönelik bir analiz yapılacaktır. Söz konusu temsilde sınıf kültürünün hangi boyutlarıyla üretildiği ve bu kültür içerisinde işçilerin duygusal dünyasının nasıl şekillendiği sorularının cevabı aranacaktır.

This study aimed to study capital budgeting for purchasing trailer projects to use with piling work, a case study of Roi-Et Prestressed Concrete Co., Ltd, in addition to comparing and summarizing the options between investment in purchasing trailers and hiring independent contractors (outsourcing). It utilized financial theories to consider the free cash flow and the weighted average cost of capital (WACC) and then determine the net present value (NPV), internal rate of return (IRR), modified internal rate of return (MIRR), payback period, discounted payback period and sensitivity study. The investment and financial management plan involved an investment cost of 3,550,000 baht, with 532,500 baht from the owner's equity and 3,017,500 baht from a financial institution loan. The WACC is 4.21%. The capital budgeting analysis based on financial theories revealed that the NPV of hiring independent contractors (outsourcing) was higher than the NPV of investment in purchasing trailers. Hiring independent contractors (outsourced) has an NPV of 8,813,386.51 baht, while the investment in purchasing trailers had an NPV of 5,997,712.07 baht. the IRR was 89.9%, and the MIRR was 34.4%. The payback period was 1.17 years, and the discounted payback period was 1.247 years. The sensitivity analysis showed that the worst-case scenario of hiring independent contractors NPV is 7,007,043.61 baht, and the worst-case scenario of investment in purchasing trailers NPV is 3,596,104.38 baht. As a result of the analysis, it can be concluded that Roi-Et Prestressed Concrete Co., Ltd. should invest in hiring independent contractors (outsource) because it has the highest net present value (NPV).

Silicon dioxide is a well-known reinforcing filler for rubbers, and its modification, called 'white soot', is often used. This filler is expensive, therefore it is of practical interest to replace it with significantly cheaper amorphous silicon dioxide obtained from rice husk. However, there is practically no scientific research concerning the use of rice husk carbonation products in isoprene rubber vulcanizates (IRV). Due to relatively low gasoline resistance of the rubber products based on IRV, it was interesting to study the effect of amorphous silicon dioxide obtained from rice husks on the swelling of vulcanizates filled with it in standard aggressive liquids. Our experiments have shown that replacing ‘white soot’ with silicon dioxide can significantly reduce (by almost 1.5–2 times) the degree of swelling of vulcanizates based on isoprene rubber. This occurs in all investigated liquids, with the least degree of swelling occurring in water and the greatest degree in toluene. Thermal aging of the samples increases the degree of swelling in all studied media, regardless of the type of filler used. At the same time, after thermal aging, the samples remain more resistant to aggressive influences when using silicon dioxide from rice husk. We associate the increase in resistance to aggressive media with a slight increase in the density of the network of vulcanizates when 'white soot' is replaced by amorphous silicon dioxide. This can be attributed to the fact that vulcanization is accelerated in alkaline environment, and the studied filler based on rice husk has the pH value in an aqueous extract of 9.97; therefore, it is able to influence the formation of rubber cross-links.
Synthesis and heterocyclization of a previously unknown S-allylthiosemicarbazone of 11H-indeno[1,2-b]quinoxaline-11-one

Published: December 2024

It is known that some derivatives of indenoquinoxaline prove to be biologically active compounds. Synthesis of 11H-indeno[1,2-b]quinoxalin-11-one has been known since about 1910, and since then considerable information has been accumulated about one of its most practically significant deriva-tives: thiosemicarbazone of indeno[1,2-b]quinoxalin-11-one. We studied the latter in the reaction with allyl bromide in a DMF-KOH-H2O medium at room temperature, which is of great interest from the point of view of obtaining S-derivatives of thiosemicarbazone of indeno[1,2-b]quinoxalin-11-one, information about which is not available in the literature. This is explained by the fact that thiosemi-carbazone of indenoquinoxaline has been previously studied mainly in reactions with bifunctional compounds, which are accompanied by molecular cyclization and, bypassing the S-substituted prod-ucts, immediately lead to synthesis of (indeno[1,2-b]quinoxalin-11-ylidene)hydrazine)thiazole sys-tems. Thus, the S-allylthiosemicarbazone of 11H-indeno[1,2-b]quinoxalin-11-one obtained by us for the first time as a result of further electrophilic heterocyclization under the action of halogens has been converted into halides of 11H-indeno[1,2-b]quinoxalin-11-ylidene-hydrazine-4-(iodomethyl)-4,5-dihydro-1,3-thiazolium. In the 1H NMR spectra of indeno[1,2-b]quinoxalinylidenehydrazine-4-(halomethyl)-1,3-thiazolium halides, the signals of the protons of the SCH2 and CH2X groups (X=I, Br) are observed in the region of 3.60–4.24 ppm, the signals of the protons of the –NH- and =N+H- groups are at 9.69–10.47 ppm and multiplets of the aromatic protons of the heterocyclic fragment are observed at 7.73–7.76; 7.83–7.84; 7.89–7.91; 7.97–7.99; 8.18–8.20; 8.20–8.22; 8.30–8.32 ppm. The single-proton signal of the =СНN+– group in the case of triiodide forms a signal at 5.83 ppm, whereas in the case of tribromide a similar proton signal appears at 6.05 ppm.

It is known that adipic acid esters are widely used in various industries, for example, as plasticizers, components of aviation synthetic oils, hydraulic and hydraulic brake fluids, and instrument oils. Their advantages are based on low toxicity, environmental safety and biodegradability. In addition, methods for producing adipic acid from renewable raw materials have now been developed. Classic acid catal-ysis of esterification using sulfuric acid has a number of disadvantages that contribute to a decrease in the yield of the product and its purity, and therefore the process is characterized by additional stages of ester purification, an increase in its cost and the formation of aggressive wastewater. Heterogene-ous catalysis is one of the methods of green chemistry. Therefore, the development of new catalysts of this type and the study of the basic principles of synthesis with their participation are relevant. In es-ter production, the choice of alcohol component is one of the main factors limiting the rate of esterifi-cation. In order to optimize the process of obtaining adipate esters, the kinetic patterns of synthesis using ethoxylated alcohols were studied. A mathematical model of the kinetic parameters of adipic acid esterification was developed, which provides maximum yield of the target ester and shorter syn-thesis duration. The main characteristics of the process of obtaining adipates of ethoxylated alcohols using catalysts of heterogeneous and homogeneous nature are considered.

The sorption of organic dyes was studied by the methods of X-ray phase analysis, spectrophotometry, and infrared spectroscopy, using methylene orange (MO) and methylene blue (MB) as a case study, by layered double hydroxide (LDH) of magnesium and aluminum with a specific surface area of ~ 200 m2/g, obtained by the low saturation method. It has been shown that the sorption capacity of lay-ered double hydroxide in the case of a solution of MO reaches 82%, and for a solution of MB it is 15%. It has been experimentally established that the sorption of dyes does not lead to structural changes in LDH, as evidenced by the absence of any significant changes in the X-ray diffraction pat-tern of the samples before and after sorption. An assumption has been made that the sorption of dyes occurs on the surface of the sample (physical sorption). The theory of physical sorption is supported by the large specific surface area of the layered double hydroxide. Possible reasons for different sorp-tion capacities for MO and MB solutions have been analyzed.

Pristine semiconductors are rarely suggested as efficient heterogenous photocatalysts, as they exhibit low efficiency, due to high recombination rate and narrow adsorption spectrum. Instead, various composites are proposed where intimate contact between two phases creates heterojunction, that improves photoactivity. In this report, we disclose a stepwise development of a grain-based hierarchical structure of photoactive composite based on anatase and poly(triazine imide) (PTI). This nanocomposite was efficient in benzyl alcohol (BA) oxidation and provided targeted benzaldehyde (BAl) with 94 % selectivity at 100 % conversion.

Published: December 2024

The purpose of the study is to analyze the mechanisms and risks of Chinese economic development during the period of global political and economic instability (2014–2023). It was found that the Chinese economy functioned based on low-cost goods exports, inequality in regional development and a high level of internal migration, strong control over the capital inflow / outflow and the cost of production, and development of infrastructure through massive direct investment due to a high level of savings. It was determined that in 2014–2023 the PRC economy faced the following risks: high dependence on exports and low domestic consumption; difficulty maintaining low production costs due to rising household incomes; decreased efficiency of investment in the economy; increased size of the state in the economy; insufficient openness and decreased efficiency of the legal system. It was shown that the functioning of the Chinese economy was supported by its unique characteristics that reduce the limitations of the «East Asian model» of economic development

Published: December 2024

The article analyzes the economic challenges faced by the Republic of Korea in the process of adapting its traditional export-oriented model to changing internal and external conditions: population aging, high inflation, the trade conflict with the United States, as well as the risks and state of the Chinese economy. The potential for a greater shift towards a model focused on domestic demand is primarily constrained by negative demographic factors. The author analyzes the dynamics of macroeconomic indicators in the Republic of Korea from 2014 to 2023 and concludes that, in order to ensure sustainable economic development, the South Korean government needs to address two key tasks: stimulate internal demand through lowering interest rates and increasing economic activity and diversify external economic ties to reduce dependence on its two main trading partners – the United States and China
An analysis of the availability, illegal supply, and demand of mangrove wood in the Artisanal Port of Sassandra, Côte d'Ivoire
Authors: Dien K.O. , Vroh B.T.A.
Published: December 2024

This paper examines the dynamic of illegal supply chain and demand of mangrove wood in Sassandra, Côte d'Ivoire. Botanical inventories and surveys across four localities and one island analyzed mangrove wood sources, distribution networks, trends, incentives, and actors involved.
Results revealed varying mangrove species densities, notably Avicennia germinans (237.7 to 525 stems/ha) and Rhizophora racemosa (487.5 to 1337.5 stems/ha). The presence of Conocarpus erectus (gray mangrove), a species that has become rare in the mangrove and swamp forests
of Côte d'Ivoire, was notable. The main driver for mangrove wood harvesting was its use in smoking fish, involving a six-stage supply chain. The key actors, namely producers, focus on the profitability of selling this wood, while buyers value its utility in fish processing. The study
underscores challenges linked to the illegal mangrove wood trade and the need for conservation policies and sustainable management of this forest resource in Côte d'Ivoire.

Ungulates have undergone major declines in Central and West African forests as a result of bushmeat trade and habitat loss. Monitoring forest ungulate status is a critical conservation need. We undertook a systematic camera-trap survey of the Ngoyla Faunal Reserve within the ∼11,000 km2 Dja-Ngoyla Complex, part of the critical TRIDOM forest landscape in Central Africa. We deployed cameras at 36 sites over 2,734 camera-trap days. We recorded 3,307 independent detections of 12 species of forest ungulates. The Peters’ duiker and blue duiker were the most abundant, accounting for 71 % of all ungulate detections, both with occupancy >85 %. The black-fronted duiker and white-bellied duiker were relatively widespread but rare. There were very few detections of Bates’ pygmy antelope, sitatunga, forest buffalo, and bongo. These findings are similar to our baseline population estimates of ungulates in the neighbouring Dja World Heritage site. Our study provides further evidence of ecological partitioning among the more abundant duikers based on activity pattern and body size. The Dja-Ngoyla Complex is integral to the 178,000 km2 TRIDOM conservation landscape. The landscape is a global conservation priority for securing the future of great apes, forest elephant, a community of forest ungulates, and other threatened species in the region.

Vibrio sp. and plankton are important microorganisms in shrimp pond ecosystems. The research aims to predict the dynamics of Vibrio sp. and plankton abundance in intensive shrimp pond ecosystems based on causal model analysis. The research method used is an ex-pose facto causal design concept with quantitative descriptive data analysis using causal dynamic modeling. The results showed the water quality in the pond has a high correlation, except Vibrio sp. and alkalinity. In the pond ecosystem 24 genus of plankton from 6 classes. Chlorella sp. is the dominant plankton genus with an abundance of 1.00E+05-4.00E+05 cells/ml. Vibrio sp. abundance in ponds ranged from 1.38E+03 - 1.31E+05 CFU/ml. Based on the results of dynamic modelling, the growth pattern of Vibrio sp. lasted for 30 weeks which was divided into 4 growth phases. The conclusion of this study is that Vibrio sp. will dynamically experience a pure growth rate for 30 weeks with details of the initial growth phase (1-7 weeks), logarithmic growth phase (8-14 weeks), exponential phase (15-21 weeks), and growth declination phase (22-30 weeks). The growth phase of Vibrio sp. has a high degree of similarity to the growth pattern of plankton in the pond water ecosystem correlatively. The novelty of this research lies in the discovery of an estimation model for the abundance of Vibrio sp. and plankton during the shrimp farming cycle. This finding can serve as a fundamental reference for farmers to optimize feeding processes and conduct regular siphoning during the peak abundance of Vibrio sp. and plankton.

Authors: Göktaş Levent Selman
Published: December 2024

This study aimed to compare the exam performances of ChatGPT Plus and Google Gemini Advanced in tourism management, tourism marketing, and tourism economics courses with the exam performance of undergraduate students. One hundred fifty students studying at Harran University Faculty of Tourism and completing their education in these three courses were selected and included in the exams with artificial intelligence models. In the exam, 25 questions were created for each course by academicians who are experts in their fields. The results show that ChatGPT has the highest overall accuracy rate and the lowest number of wrong answers. ChatGPT gave 21 correct answers in the tourism economics exam, Google Gemini 18, and students 16.6. In the tourism marketing exam, ChatGPT 19 and Google Gemini 18, students gave 14.9 correct answers. In the tourism management exam, ChatGPT answered 22 questions correctly, Google Gemini answered 14 questions, and students answered 16.3 questions correctly. In addition, the questions were categorised as short, long, easy, medium difficulty, complex questions, negative sentences, and scenario questions. When the results were analysed, ChatGPT was more successful in all categories. Although artificial intelligence language models are more effective than undergraduate students in certain exam conditions, this study underscores the need for further research to optimise and validate the use of these technologies in education. In addition, as a result of the research, it is thought that artificial intelligence language models can play a transformative role in tourism education in the future. An important finding has also emerged that ensuring the ethical and practical use of artificial intelligence technologies in academic settings requires responsible integration, human oversight, and more validation studies.
