Authors: Veklich A. , Murmantsev A. , Boretskij V.
Published: December 2024

This work is devoted to the investigation of plasma parameters (excitation temperature and electron density) of the underwater discharge between two types of metal granules, in particular: between single-component granules of copper or molybdenum, copperized molybdenum, and both copper and molybdenum with a volume ratio of 50%. Optical emission spectroscopy was used to study such plasma of underwater spark discharges between different types of granules. Namely, the excitation temperature was determined by the Boltzmann plot technique, and the electron density was obtained from the width of the spectral lines of hydrogen and individual lines of metal atoms, assuming that the Stark effect is the dominant mechanism of roadening.

Published: December 2024

Araştırmanın ana amacı, Giresun'da coğrafi işaret almış fındığın, şehrin markalaşma sürecindeki önemini incelemektir. Bu çalışma şehirlerin markalaşmasında coğrafi işaretli ürünlerin rolünü, uluslararası alanda tanınan Giresun fındığı örneği üzerinden değerlendirmektedir. Araştırmada, nicel yöntemler ve tarama desenine dayalı anket yöntemi kullanılmıştır. Coğrafi işaretli ürünler ve geleneksel mutfak kültürü, şehirlerin marka değerini oluşturma sürecinde önemli bir etkiye sahiptir. Yerel tarımsal üretimin desteklenmesi, bölgenin ekonomik anlamda gelişimine katkıda bulunur ve bölgenin tanıtımını güçlendirir. Bu süreçte, şehirlerin tarihi ve kültürel zenginlikleri daha görünür hale gelir, bu da şehir markalaşmasına pozitif bir ivme kazandırır. Araştırma, coğrafi işaretli ürünlerin şehir markalaşmasındaki kritik rolünü vurgulayarak, literatüre yeni bir bakış açısı sunmayı amaçlamaktadır ve bu konuya ilgi duyan diğer şehirler için de yol gösterici olabilir. %5 hata payı ve %95 güven aralığıyla örneklem büyüklüğü belirlenmiş olup (Aziz, 2003, s. 58), 7944 kişilik bir evren için 367 katılımcıya anket uygulanmıştır. Örneklem seçimi yapılırken, her bir katılımcının seçilme olasılığının bilinmediği olasılıksız örnekleme yöntemi tercih edilmiş ve zaman yönetimi açısından kolaylık sağlayan rastgele örnekleme yöntemi kullanılmıştır. Araştırmanın bulguları, şehir markalaşması ile coğrafi işaretli ürünlerin etkileşimi üzerine daha kapsamlı bir anlayış geliştirilmesine katkı sağlayabilir. Bölgenin kendine özgü niteliklerini ve yüksek kalitesini öne çıkararak, o bölgenin hem tanıtımına hem de ekonomik gelişimine katkıda bulunulabilir. Sonuçlar, coğrafi işaretli ürünlerin şehir markalaşmasına olumlu etkileri olduğunu ortaya koymaktadır. Bu etkinin en üst düzeye çıkarılması için, yerel yöneticilerin coğrafi işaretlerle ilgili bilinçlendirme ve tanıtım çalışmalarını hem bölge halkına hem de ziyaretçilere yönelik olarak yaygınlaştırmaları gerekmektedir.
Speed Optimizations to Parzen Window Classifier Using Probability Approximation, Discretization and Compression
Authors: Baykal İbrahim Cem
Published: December 2024

Parzen window estimators can model any type of complicated probability density manifolds. However, when it comes to real life applications, they are not as popular as the Artificial Neural Networks or the Support Vector Machines. That is mainly because Parzen window classifiers require long and complex calculations during the classification process. This article introduces speed optimization methods for Parzen window classifier that makes this classifier faster than any other convergent classifier at a small performance cost. The method includes, discretization, look-up tables, approximation, and probabilistic compression. Experiments conducted on both computer generated and real-life data prove that the resultant classifier is only slightly less accurate than Artificial Neural Networks and Support Vector Machines while immensely faster.

Authors: Şahin Tevfik , Özyurt Gülnur
Published: December 2024

This paper investigates position vectors of arbitrary curves in isotropic 3-space (denoted by I^3). We first establish the relationship between a curve’s position vector and the Frenet frame. Then, we derive a natural representation of any curve’s position vector using curvature and torsion. Furthermore, we define various curves within isotropic space, including straight lines, plane curves, helices, general helices, Salkowski curves, and anti-Salkowski curves. Finally, graphical illustrations accompany illustrative examples to elucidate the discussed concepts.

Published: December 2024

Parasitic infections caused by helminth, protozoa, and ectoparasites pose a threat to animal and human health due to clinical changes and transmission of potentially zoonotic agents. This study's objective was to assess parasitic diseases in dogs admitted to the Selcuk University Veterinary Faculty Animal Hospital (SUVFAH) between 2015 and 2021. Fecal, blood, and skin samples sent to the laboratory of the Department of Parasitology, Faculty of Veterinary Medicine were examined. The majority of samples (n = 846) were collected from domestic dogs, and only 49 were from shelter dogs. During the study period, 33.74% (302/895) of the dogs tested positive for at least one parasite, including single (29.83%), double (4.63%), triple (0.14%) and quadruple (0.14%) internal parasite infections. This study revealed that the prevalences of protozoan and rickettsial parasites, including Isospora spp., Giardia duodenalis, Sarcocystis spp., Entamoeba histolytica, and Ehrlichia canis in dogs from Konya province, were 7.01%, 26.79%, 1.26%, 0.7%, and 5.26%, respectively. On the other hand, the prevalences of helminthic parasites Toxascaris spp., Trichuris spp., Anyclostoma spp., Uncinaria spp., Dipylidium caninum, Taenia spp. and Mesocestoides spp. were 0.14%, 0.42%, 0.42%, 0.42%, 0.42%, 0.42% and 0.14%, respectively. As ectoparasitic infestations, 11.66% Demodex canis infestation and 0.61% myiasis cases were encountered. Although most of the dogs in the study were owned, the rate of internal and external parasite infection/infestation was high. In this case, pet owners have a great responsibility to prevent parasitic infections in pets, which are the source of many parasitic agents with zoonotic properties.

A New Type of Extended Soft Set Operations: Complementary Extended Difference Operation
Authors: Sezgin Aslıhan , Akbulut Emre , Demir Hüseyin
Published: December 2024

Soft set theory has many theoretical and practical applications. It was first introduced by Molodtsov in 1999 as a way to represent specific situations including uncertainty. The fundamental building blocks of soft set theory are soft set operations. Since its debut, several types of soft set operations have been defined and utilized in diverse contexts. In order to further the theory, a new soft set operation known as the complementary extended difference operation is defined in this paper. Its properties are thoroughly discussed, with particular attention to how it differs from the difference operation in classical sets. Additionally, the distribution of this operation over other types of soft set operations is examined in order to determine how this operation relates to other soft set operations.

Traditional mathematics instruction frequently neglects the cultivation of creativity and creative self-efficacy in elementary school students, as it prioritizes procedural problem-solving techniques and memorization strategies. This study examines the influence of creative mathematical tasks and task modification activities as indicators of creativity on the creative self-efficacy and creativity skills of students. This quasi-experimental study consists in pretests and control groups. Whereas the experimental group participates in learning by means of creative tasks and activities that change mathematical assignments to inspire artistic thinking, the control group follows conventional teaching tactics. Interviews with students helped to compile data on their experiences throughout task modification activities, written tests including creative projects, and self-efficacy creative relieving.

The findings indicated a notable enhancement in creativity skills and creative self-efficacy among students in the experimental group relative to the control group. Task modification activities engage students in advanced cognitive processes, foster the generation of innovative and adaptable solutions, and enhance their confidence in addressing mathematical challenges. This result shows that include creative mathematical activities and letting students modify their assignments will help to improve mathematics instruction and inspire early on creativity and confidence. This study proposes that in order to improve students' creative self-efficacy, teachers include student-led task modifications and problem-based task in mathematics education. The long-term consequences of this method and its relevance to other mathematical materials will be investigated in next studies.

Altınova'da seracılık sektöründe çalışan dış göç ile gelmiş olan kadınların emeği üzerine nitel bir değerlendirme
Authors: Göktaş Sümeyye , Keleşoğlu Fikri
Published: December 2024

Bu çalışmanın amacı Yalova ilinin Altınova ilçesine uluslararası göç ile gelmiş, seracılık sektöründe çalışan göçmen kadınların işgücü piyasalarına katılımının toplumsal cinsiyet rolleri ile ilişkisini incelemektir. Türkiye içinde bulunduğu jeopolitik konum ile her zaman göçmenler için bir transit ülke özelliği göstermiştir. Bunun yanı sıra özellikle 2010 yılında gerçekleşen ve pek çok Orta Doğu ülkesini etkisi altına alan “Arap Baharı”nın etkisiyle Orta Doğu ülkelerinden Türkiye’ye kitlesel göçler gerçekleşmiş ve bu kitlesel göçler ile Türkiye’ye giriş yapan göçmenler Türkiye’nin emek piyasalarına dâhil olmuştur. Literatürde göçmen emeğine dair pek çok çalışma yapıldığı görülmekle birlikte göçmen kadın emeğine dair çalışmaların nicel anlamda sınırlı kaldığı görülmektedir. Yapılan çalışmalar genellikle göçmen kadınların ev hizmetleri, bakım hizmetleri, turizm gibi sektörlerdeki emeğine odaklanmış olup göçmen kadınların seracılık sektöründeki durumlarını inceleyen bir çalışmaya rastlanılmamıştır. Bu sebeple bu çalışma Yalova ilinin Altınova ilçesinde seracılık sektöründe çalışan göçmen kadınların emeğinin değerlendirilmesine yönelik yapılmıştır.
Yalova ilinin Altınova ilçesinde 2023 yılında gerçekleştirilen çalışma, Türkiye’ye göç etmek zorunda kalan farklı etnik gruplardan olan 10 kadın ile yapılan görüşmelere dayanmaktadır. Kadınların toplumsal cinsiyet rollerinin getirmiş olduğu “kadının yeri evidir” algısı ile emek piyasalarında var olma çabası uzun yıllardır devam etmektedir. Göçmen olmanın getirmiş olduğu ikincil dezavantaj ile birlikte göçmen kadınların emek piyasalarındaki konumu onları daha da kırılgan bir grup haline getirmektedir. Nitel araştırma yöntemi kullanılan bu çalışma göçmen kadınların işgücü piyasalarında, toplumsal cinsiyet rollerinin getirmiş olduğu kırılgan, kolay yönetilebilir ve ucuz emek algısı sonucunda düşük ücret, sosyal dışlanma, niteliksizleştirme, mevcut işe devam etmeye zorunlu olma gibi pek çok sorunlarla mücadele ettiğini göstermektedir.

Nutrient balance and productivity of crop rotations as affected by their structure and fertilisation
Authors: Ivanina V. V. , Prokopiuk T. P.
Published: December 2024

Purpose. To investigate the influence of fertilisation systems on the productivity of short crop rotations and the formation of the balance of nutrients in the soil.
Methods. Long-term field and analytical.
Results. The productivity of crop rotations and the balance of nutrients in the soil depending on their structure and fertilisation systems are presented. It was established that organic-mineral fertilisation systems formed the highest fodder productivity of crop rotations and the best indicators of the balance of nutrients in the soil.
Conclusions. Application of N53Р42K42 + 6.7 t of manure per 1 ha of arable land in crop rotation provided the highest fodder productivity of 9.2 t/ha with an advantage over control without fertilisers of 3.8 t per 1 ha of crop rotation area. The application of conventional and alternative organic-mineral fertilisation systems was determined to be effective in row crop rotation: the productivity of crop rotation was 8.4 and 8.3 tons of fodder units per 1 ha of crop rotation area, respectively. Organic-mineral fertilisation systems formed an optimal balance of nitrogen in grass and grain and row crop rotations with the intensity of the balance of 94–95% and 100–103%, respectively. In the grain and row crop rotation, the nitrogen balance was negative at the intensity of 82–84%. In all crop rotations, the combined application of organic and mineral fertilisers contributed to the accumulation of phosphorus in the soil and formed a positive phosphorus balance at an intensity of 103–115%. None of the fertilisation systems provided a positive balance of potassium in the soil. The best indicators of potassium balance in crop rotations were formed by applying N53Р42K42 per 1 ha of arable land + by-products with a potassium deficit of 33–41 kg/ha of the crop rotation area and the intensity of its balance of 73–78%.
The name of the compound and allelopathic effect of metabolites produced by common ragweed (Ambrosia artemisiifolia L.)
Authors: Storozhyk L. I. , Mykhailovyn Yu. M.
Published: December 2024

Purpose. To identify the phytochemical composition of the aboveground biomass of Ambrosia artemisiifolia L., the effect of its root exudates on major crops within agroecosystems, and the competitiveness of this weed species compared to other plants.
Methods. Allelopathic, chemical, physiological-biochemical, analytical, and statistical methods.
Results. The biomass of A. artemisiifolia contains a high concentration of essential physiologically active components, with coumarins being the most prevalent at 2.97%. The roots of A. artemisiifolia release protocatechuic acid, n-hydroxybenzoic acid, vanillic acid, syringic acid, n-coumaric acid, and ferulic acid into the rhizosphere. Phytotoxic extracts from the vegetative organs of A. artemisiifolia reduced seed germination in winter pea by an average of 37–50%, in maize by 27–40%, in sorghum by 17–22%, and in sugar beet by 12–28%. Root phytotoxic extracts and rhizosphere soil extracts significantly decreased seed germination in the studied crops: in winter pea by 71% and 78%, respectively, in maize by 42% and 38%, respectively, in sugar beet by an average of 26%, and in sorghum by 33% and 16%. Sunflower demonstrated the highest resistance, with seed germination reduced by only 7%, 5%, and 4% when treated with phytotoxic extracts from the stems, leaves, and inflorescences of A. artemisiifolia, respectively. Phytotoxic extracts from the soil and roots reduced sunflower seed germination by 11% and 6%, respectively. The highest competitiveness against the allelopathically active components of the weed species was exhibited by yellow mustard (Sinapis alba), sorghum, and creeping couch grass (Elymus repens), as their phytotoxic soil extracts reduced A. artemisiifolia seed germination by 75%, with creeping couch grass and sorghum extracts reducing germination by 88% and 68%, respectively.
Conclusions. Water extracts from the vegetative and generative organs of A. artemisiifolia contain significant amounts of physiologically active components that impact the quality of seed germination in the studied crops. It was found that sunflower seeds are resistant to the allelopathically active substances of the A. artemisiifolia. Yellow mustard, sorghum, and creeping couch grass demonstrate resistance to the phytotoxic components of A. artemisiifolia, due to their high levels of phytochemical compounds capable of inhibiting seed germination of this highly allelopathic weed.

Authors: Samaniego Balseca Maria Darnely , Lara Hernández María Elena , Salazar Chiriboga Andrea Stephania , Nicolalde Castillo Gonzalo Andrés
Published: December 2024

El linfoma primario de mama se considera una enfermedad poco frecuente con una incidencia inferior al 1% de todas las neoplasias malignas de mama y representa menos del 2 % de los linfomas no Hodgkin. Su presentación inicial puede semejar características benignas como masa indolora simétrica móvil, con posterior empeoramiento del cuadro y rápida progresión. El diagnóstico por imagen puede llegar a ser confuso con presentación de características malignas y benignas. La cirugía no cumple un rol fundamental en el tratamiento como en otros canceres de mama. Su reconocimiento y tratamiento tardío hace que sus resultados sean desfavorables. Así se describe el siguiente caso: Mujer joven con VIH en tratamiento y control de su enfermedad con tratamiento antirretroviral, contaje de CD4 adecuado. Con diagnóstico de linfoma no Hodgkin difuso de células B grandes, presenta múltiples ingresos por sobreinfección, fracaso de tercera línea de quimioterapia y radioterapia paliativa con progresión de enfermedad hasta la muerte.

Published: December 2024

Clustering analysis primarily highlights the in homogeneity of data and can be utilized in structural engineering to demonstrate strength irregularity. It is well-known that strength irregularity between neighboring floors within a structure or among structural elements can lead to non-holistic behavior. Therefore, the clustering of compressive strength holds significant importance. Despite the relevance, only a few studies have addressed the clustering of compressive strength in recycled aggregate concrete (RAC) and proposed potential solutions for clustering issues. This paper aims to investigate the clustering of compressive strength in RAC and explore viable solutions. In this experimental study, four concrete groups were produced under standard conditions. The first group included natural aggregate concretes (NAC) designed with the Absolute Volume Method (AVM) as control concretes. The second group, comprised of RAC, was designed with the equivalent mortar volume method (EVM) as the control RAC. The third group consisted of RAC treated with silica fume (SF) and designed using AVM, while the fourth group included RAC designed with EVM. Statistical analyses were conducted on the 28-day compressive strength test results. The results indicated that the strength class of compressive strength clusters varied among the four groups. The clustering of test results was influenced by the type of concrete components used and the design method employed. Additionally, using silica fume and adopting the Absolute Volume Method reduced strength fluctuation and regulated the strength class of clusters by bringing them closer together. In contrast, the Equivalent Mortar Volume Method resulted in a greater dispersion of strength classes. The clustering effect of recycled aggregate (RA) was more pronounced than that of natural aggregate (NA). Given these findings, it is essential to implement measures when utilizing RAC in sustainable structures to address potential clustering issues.
One-part alkali-activated mortars based on clay brick waste, natural pozzolan waste, and marble powder waste

Published: December 2024

In Türkiye, waste clay bricks (WCB) comprise significant construction and demolition waste. Most research is based on producing WCB-based two-part alkali-activated materials (AAM). Compared to their conventional, two-part alkali-activated counterparts, one-part AAM offers several advantages, such as being more practical, safe, and easy to use. Thus, they may be an excellent choice for commercial construction applications and on-site casting. However, research data on producing WCB-based one-part alkali-activated mortars is limited. The relatively low reactivity of WCB can be increased by replacing WCB with ground granulated blast-furnace slag (GGBS) and fly ash (FA). Unlike these by-products, Nevşehir pozzolan (NP) and marble powder (MP), which are produced as wastes during the stone-cutting process, may be evaluated to produce AAM. This study aims to assess the production possibilities of WCB-based one-part alkali-activated mortar, determine the optimum substitution ratios with NP and MP o improve the mechanical properties, and determine the effects of the curing period up to 365 days. Results showed that the optimum NP substitution ratio was 50%, which increased reaction development, microstructure compactness, and mechanical properties. The highest CS (UV) (3.70 km/s) and compressive strength (CS) (21.58 MPa) were obtained in 25WC-B:75MP-containing samples. The increase in properties with the curing period was especially high in the first 28 days.

Authors: Ünver Güray
Published: December 2024

This article presents a new funerary inscription on a stele from Mylasa. The stele was found in the area to the southeast of Esentepe during the sondage excavation held under the supervision of the Milas Museum in 2021. The text is the funerary inscription of 11 members of a thiasos who claimed to be buried together at the same place when they die. According to the inscription, Ouliades son of
Euthydemos was heroized with divine honors after his death, and the thiasos was established in his honor. The members of the thiasos (θιασεῖται Ἡρωϊσταί) dedicated a bomos to the heros Ouliades on the street called “the street of Skorpon.” The heros Ouliades, who became the object of a cult, was the son of Euthydemos, the well-known leader of the city in the first half of the first century BC. Therefore the inscription is dated to the late first century BC - first century AD due to letter forms and prosopography.

This research aimed to analyze the determinants of efficiency and competitiveness in the manufacturing sector, encompassing GDP per capita, ease of doing business, technology, and several variables indicative of governance quality, such as corruption control and government effectiveness. Competitiveness in this study is measured using the concept of Revealed Comparative Advantages (RCA) introduced by Balassa (1965) employing Panel Corrected Standard Error (PCSE) estimation technique. Simultaneously, manufacturing efficiency is gauged utilizing the Data Envelopment Analysis (DEA) method, a nonparametric approach applied to compute the efficiency of a group of decision-making units (DMU). The findings reveal that GDP per capita, Technology, Government Governance Index, and Nominal Exchange Rate significantly and positively influence RCA. Conversely, Ease of Doing Business is found to exert a significant negative impact on RCA. Furthermore, the DEA efficiency scores indicate values of 1 for several African countries, including the Democratic Republic of Congo, Eswatini, and Burundi, and also find high efficiency in certain Asian countries such as China, Thailand, Malaysia, and Indonesia. Efficient allocation of capital (Gross Fixed Capital Formation) and labor (Labor Force in the Industrial Sector) optimizes output (Manufacturing Share of GDP). This study holds implications for enhancing the driving factors of competitiveness and optimizing efficiency in the manufacturing sector across developing countries worldwide.
Analysis of Public Debt in the Context of Crises Generated by Socio-Economic Events. Case Study: European Union Countries
Authors: Strachinaru Alin Vasile
Published: December 2024

In the current geopolitical configuration, generated by socio-economic and political-military events, with an impact on economic development, the public debt dynamics take on new dimensions. Public debt, as an indispensable concept for improving development strategies in an economic and geopolitical context, is influenced by the macroeconomic indicators’ variation, but also by the internal and external factors’ impact, which generate instability in a dynamic of unpredictable phenomena. Therefore, the study indicates proposals, based on multivariate regression, to capture the most sensitive variations of macroeconomic indicators on sustainable development at the European Union countries level. Moreover, the current European level configuration requires a detailed capture of the connection between public debt and economic growth, by using a VAR model (public debt, a concept that takes on new values in the current context, and economic growth, as the central pillar of sustainable development, analyzed from the perspective of the studied indicators fluctuation). Finally, I analyzed the public debt dynamics for the next period (2000 – 2022) to create a realistic picture, using the ARMA model. The results confirm the direct impact of each event on economic growth and development, and the limitation and elimination of negative effects vary depending on how it is managed and prevented. Also, the link between the economic growth and public debt is confirmed and, at the same time, it constitutes a benchmark that captures the importance of the decisions of the responsible factors regarding the financial-monetary instruments implemented or what is requested to be adopted. In other words, forecasting the public debt dynamics gives a certain stability, but also a strategic vision, offering viable solutions to support sustainable development efforts at European states level.
Network Effects on Platform Markets. Revisiting the Theoretical Literature
Authors: Soares Isabel , Nieto-Mengotti Manuel
Published: December 2024

The characteristics of the bilateral network markets were already studied before 2003, but they focused on specific markets (credit cards or newspaper advertising) without relating implications with third parties. But since the emergence of new business models based on digital platform markets, especially since 2007 with the arrival of the smartphone, business scalability and network effects have skyrocketed. In this article, we carry out a review of the main contributions on network effects in the markets and their implications for the governance of platforms, which is of vital importance to understand the regulatory impacts when trying to limit the effects. negative effects of the market power. In the end, we found that in most studies, same-sided negative network effects are rarely considered, so despite multiple analyzes and empirical studies, there may still be some blind spots in the analysis of the network effects for the platform economies that can be transcendental for the understanding of all the market variables affected by the governance of platforms in monopolistic competition.

Published: December 2024

The study investigates the complex relationship between self-congruity (perceived fit between one’s values or personality with a brand), customer engagement, and marketing personalization while examining how AI can enhance personalization strategies. Customer engagement is observed as a major consequence of self‐congruity, the compatibility between a consumer’s brand image and his or her self-concept. Consumers who feel a brand represents their values and sense of self-interest are becoming ever more likely to try the products or services connected. This depth of engagement is reinforced by marketing personalization, where outbound and inbound experiences behave to the consumer according to their preferences on offers.
