A Countable Intersection Like Characterization of Star-Lindelöf Spaces
Authors: Bal P.
Published: December 2023

There have been various studies on star-Lindelöfness but they always explain it in terms of open coverings. So, we have demonstrated in this study a connection between star-Lindelöfness and the family of closed sets that resembles countable intersection property of Lindelöf space. We show that a topological space $X$ is star-Lindelöf if and only if every closed subset's family of $X$ not having the modified non-countable intersection property have non-empty intersection.

Perspektywy wolności ciała w "Samuelu Zborowskim" Juliusza Słowackiego
Authors: Rzepniewska-Kosińska Anna
Published: December 2023

Celem artykułu jest uzupełnienie badań nad kondycją człowieka w myśli genezyjskiej Juliusza Słowackiego, w której nieograniczona swoboda ducha wydaje się kwestią oczywistą, w przeciwieństwie do wciąż nie dość naświetlonej wolności ciała. Na przykładzie Samuela Zborowskiego można wykazać, że – wbrew stereotypowej wizji Słowackiego jako mistyka pogardzającego materią – poeta nie aprobuje samowoli ducha ciemiężącego ciało w doczesnym świecie genezyjskim i postuluje naprawę relacji między tymi dwiema sferami. Pomysł romantyka na dążenie do harmonii na tym polu można rozumieć jako poszanowanie przez ducha negatywnej wolności ludzkiej formy przy jednoczesnym jego prawie do ograniczania cielesnej wolności pozytywnej.
Wspólnotowe i prywatne przestrzenie wolności w kaukaskiej literaturze zesłańczej
Authors: Gadamska-Serafin Renata
Published: December 2023

Kaukaska literatura emigracyjna XIX wieku kumuluje zapisy różnych sposobów doświadczania wolności pomimo fizycznego zniewolenia. Obiektywną, zewnętrzną formą manifestowania wolności, często przybierającą charakter wspólnotowy, było prowadzenie politycznej misji „apostolskiej” polegającej na głoszeniu idei wolności; prowadzenie badań i pracy naukowej, utrzymywanie więzi z literaturą narodową, czytanie indywidualne lub głośne w grupie zesłańców. Nie mniej ważne było jednak „dotykanie” wolności w indywidualnym, subiektywnym wnętrzu: poprzez uwolnienie nieograniczonych przestrzeni wyobraźni i uruchomienie procesów twórczych twórczego „ja”; dzięki marzeniom i pamięci; w miłości, wreszcie w kontakcie z naturą, która była dla romantyków bramą do transcendencji. Istotą tych poetyckich wizji „wyzwolenia” jest w istocie projekcja powrotu do Raju.

The Bullish Game: The Role of Virtual Currency in Incentivizing Homework on the Skyeng Platform
Authors: Адамович Ксения , Чиркина Татьяна
Published: December 2023

Even though online learning is an affordable way to gain new knowledge and skills, and millions of people use different platforms, there is a serious problem with students dropping out, as well as with their completion of assignments during training. One effective way to increase student engagement is to use gamification in teaching. In this study, we study the relationship between the introduction of such a gamification element as virtual currency with the results of learning English on the Skyeng platform. Using data from 2019 to 2020, we analyzed the relationship between the indicated intervention and the percentage of completion of homework, as well as the average homework score of platform users. 

The results of the experiment conducted in the A/B format showed that the introduction of virtual currency had a significant effect on the educational results of students. Thus, students from the experimental group showed an increase in involvement in doing homework on the platform compared to the control group. Moreover, various types of rewards work in general to increase student engagement in homework, including those that are not directly related to learning. At the same time, students who did not use the game currency available to them showed similar or even lower results than participants in the experiment from the control group. It can be assumed that in this case there is an effect of student motivation as a hidden factor, which explains the greater interest in the functionality and capabilities of the platform itself, and in the educational process as a whole.
A novel method for the isolation of single cells mimicking circulating tumour cells adhered on Smart Bio Surface slides by Laser Capture Microdissection v1
Authors: Visci Grazia
Published: December 2023

In recent years, the importance of isolating single cells from blood circulation for several applications, such as non-invasive tumour diagnosis, the monitoring of minimal residual disease, and the analysis of circulating fetal cells for prenatal diagnosis, urged the need to set up innovative methods for such application. Different methods were developed. All show some weaknesses, especially a limited sensitivity, and specificity. Here we present a new method for isolating a single or a limited number of cells adhered to SBS slides (Tethis S.p.a.) (a glass slide coated with Nanostructured Titanium Dioxide) by Laser Capture Microdissection and subsequent Whole Genome Amplification. SBS slides have been shown to have an optimal performance in immobilizing CTC from early breast cancer patients. In this work, we spiked cancer cells in blood samples to mimic CTCs. By defining laser parameters to cut intact samples, we were able to isolate genetically intact single cells. We demonstrate that SBS slides are optimally suited for isolating cells using LCM and that this method provides high-quality DNA, ideal for gene-specific assays such as PCR and Sanger sequencing for mutation analysis.

Bitumen is a widely used road infrastructure material exhibiting black color and sticky consistency and is known for its versatile use and thermoplastic nature. In recent years, predicting road life has been arduous due to increasing traffic, global warming, and ever-changing stresses on pavements. Meanwhile, a large amount of waste engine oil (WEO) and vehicle tyres from various automobiles is disposed of into the atmosphere as hazardous waste. Relatedly, heavy metals and the huge capital involved in the sustainable treatment of these materials have been challenging. Therefore, this study aims to analyze modified bitumen using (WEO) in combination with waste crumb tyre rubber (CTR), thus reducing virgin bitumen (VB) use and making bitumen a sustainable material. During the characterization of modified bitumen, the following WEO concentrations were utilized: 3%, 5%, 7%, and 9%, and the following CTR concentrations: 5%, 7%, 9%, 12%, and 15%. The properties of modified and virgin bitumen were compared. It has been found that the blend of 5% CTR and 9% WEO exhibit the highest penetration value and the lowest softening temperature of all the samples examined. As a result, this mixture can be used to reduce the excessive brittleness of bitumen to a greater extent. Moreover, the flash and fire point values have increased after modification, while the ductility and specific gravity values have decreased. In summary, the modified bitumen has shown promising results regarding physical changes in bitumen.

In order to further reduce oil dependence and world pollution, there’s growing interest in embedding batteries such as Li-Po batteries within vehicle components. The implementation of structural batteries is believed to be the next promising approach for next-generation hybrid and electric vehicles. The proposed research is devoted to the uncertainty analysis of structural battery behavior under various parameters. To help with the analysis, a dedicated algorithm based on an elimination approach to solve numerical problems with uncertain parameters is successfully developed using Visual Basic. The Constant Strain Triangle element with linear elastic behavior is used as a structural model to simplify the model. Uncertainty of the material properties and loading are modeled as Fuzzy Random Variables. In evaluating the influence of the uncertainty parameters, Interval Monte Carlo Simulation and the interval finite element method are used to compute the bounds of the structure behavior. Simulation results between the Interval Monte Carlo and Deterministic are compared to evaluate the significance of the uncertainty factor influences. It is shown that the structural batteries that can be considered safe based on deterministic parameters may be unsafe if the uncertainty parameters are considered. The proposed approach could detect the results that are not necessarily detected through deterministic means. By producing a broader result, further prevention and consideration can be made to avoid catastrophic events.

iocomposite is a combination of natural reinforcement and natural matrix material consisting of kenaf reinforced with polylactic acid (PLA), where its mechanical properties will be affected when exposed to heat. This research investigates the effect of exposure of biocomposites to different temperatures on the mechanical properties of biocomposites, consisting of tensile and flexural properties. Before producing the sample, kenaf in the form of one-way yarn is conditioned with 40% RH humidity, and then the sample is produced using hot compression molding techniques by combining kenaf with PLA. Tensile and bending tests carried out in a heating chamber with the heat were studied using a Universal Testing Machine (UTM). The choice of heat temperature depends on the glass transition temperature of polylactic acid, where the study temperature ranges from 25 oC to 65 oC. From the results of the study, it was found that the maximum bending strength and modulus (117 MPa, 5.8 GPa) and the maximum tensile strength and modulus (59 MPa, 3.2 GPa) were both obtained at low temperatures (25 oC). While the modulus value decreases significantly at 55 oC, the tensile and flexural properties both show a steady decrease with increasing temperature. Therefore, the presence of temperature has a significant effect on the tensile and flexural properties of kenaf-reinforced PLA biocomposites. When it is exposed to high temperatures, the mechanical quality deteriorates, and the risk of failure increases. Failure is caused by poor reinforcement and matrix bonding caused by the degradation of natural fiber properties of kenaf and the level of PLA plastic deformation.

This paper presents a case study of an existing slope at Taman Kelab Ukay, Ampang, Selangor. A potential slope failure is predicted as the nearby surrounded slope failed due to low self-retaining strength caused by prolonged and intense rainfall. The slope stability is analyzed by the Limit Equilibrium Method (LEM) using Geo-Studio 2018 (SLOPE/W) software to investigate the slope’s Factor of Safety (FOS). The slope stability analysis confirms that the existing slope only provides the FOS of 1.028, which does not meet the minimum FOS of 1.30 of JKR Guidelines for Slope Design (2010) for untreated slope. The slope is subsequently re-analyzed as a treated slope, and the proposed remedial actions are soil nailing and geotextiles. As a result, the soil nailing and geotextiles achieve a minimum FOS of 1.50 for treated slope, with values of 1.899 and 1.845, respectively. For remedial work, soil nailing is recommended to be employed at the slope since the method is commonly used in the construction industry as it offers an inexpensive and uncomplicated installation technique. The sufficient soil nailing design characteristics proposed for the slope is three (3) bars of 7 meters length of soil nails at a 25° inclination angle. Soil nailing is a reliable and cost-effective method for slope stabilization and remedial work due to its ability to provide a durable, long-term solution for slopes that are prone to instability, erosion and landslides.

Bitumen is a hydrocarbon material which can be largely obtained from crude petroleum distillation. It used widely in flexible pavement construction as a binder that binds the aggregate. Flexible pavements make up around 95% of the pavement in entire world. The quality of the materials used in the flexible pavement is essential for its performance. The modification of bituminous binders using modifiers is applied to improve the quality and properties of bitumen. Due to the limitation of crude oil, higher price, and impact of bitumen on the environment, an efficient, cost-effective, and environmentally friendly modifier for the modification of bituminous binders is vital in road industry. This paper aims to provides a review and propose the waste materials that can be used as modifier or bitumen extender. Among these waste materials, silicon, rubber, cooking oil (mix with other modifiers) lignin and calcium lignosulfonate shown a promising results as bitumen extender. Furthermore, the cost analysis of the modified bituminous binders was also look upon. The findings from this study recommend lignin among the extender being compared. Lignin can be mixed directly in the bitumen with a minimal process involved. Moreover, lignin is a biobased waste materials and the second most abundant organic material on earth, after cellulose. With 25% replacement of bitumen, lignin reduces the consumption of non-renewable bitumen and has a great potential to be used in pavement construction.

Climate chambers play an important role in the design and testing process. Several different chambers have been built over the years, specialising in different areas. It means there is a wide choice on the market and as a consequence, parameters necessary for us limit when choosing the ideal test chamber. Our instruments might be subjected to several environmental effects which require a lot of time and effort to be tested. An example is the Mars rover. NASA's Perseverance Mars rover was equipped with 2 pieces of Li-ion battery packs and the old solar charging was replaced by RTG (Radioisotope Thermoelectric Generator) thus a generator feeds the electricity consumers of the rover. Temperature on the surface of Mars varies from -150 C° to 20 C°. In addition, there are huge storms at regular interval lasting for month sometimes. These storms cause great difficulties because, on the one hand, the main power source on older types was the solar panels, and storms can cover them with Martian dust, limiting or eliminating their power supply. On the other hand, large sandstorms can completely cover the rover, and once the sandstorm is over, the Mars rover has to free itself from its trap. In addition, there were many other factors that engineers had to consider in the design. It is a well-known fact that we are not able to consider all the possible environmental conditions in design, and it is also known that some measurements may be inaccurate, so the prototypes produced have to be tested on the ground. The ground tests must ensure that the operating conditions on Mars are maintained. Special test chambers have been developed for this purpose. [1] The aim of the authors is to design and build a prototype of a climate chamber of their own design. An important component of the chamber is a measurement data acquisition system, which allows the collection of measured data and their preliminary processing.

Рассматривается найденный в бухте Круглая близ г. Севастополя фрагмент амфоры, которая была наполнена коричневым веществом с характерным запахом дегтя. На горловине сосуда имеется круглое клеймо диаметром ок. 30 мм с изображением императора и надписью вокруг него. Установлено сходство штампа с клеймами на амфорах из Александрии и с о-ва Геронисос; восстановлена надпись: «επί Πτολεμαίου επάρχου». Основное внимание уделяется детальному химическому анализу содержимого сосуда. Методом газовой хроматомасс-спектрометрии выявлены дегидроабиетиновая кислота, метилдегидроабиетат, норабиетатриены, ретен и другие производные фенантрена, что свидетельствует о том, что содержимое амфоры является продуктом сухой перегонки древесины семейства сосновых. В результате парофазного анализа обнаружены компоненты скипидарного масла — а-пинен, камфен, лимонен, цимолы и другие терпены. Для определения происхождения содержимого амфоры проведен его сравнительный анализ с современным сосновым дегтем, полученным традиционным способом. С учетом идентичного профиля хроматограмм содержимого амфоры и дегтя в области смоляных кислот, близких по значениям площадей пиков компонентов, являющихся биомаркерами, а также наличия в образце компонентов скипидарового масла сделан вывод о том, что с большой долей вероятности содержимым амфоры являлся именно деготь.

Energy crisis is the most popular issue in the world, which must be overcome with the development of alternative energy sources. Among them, methanol is a promising fuel when used in direct methanol fuel cells. However, the mentioned cell needs highly electroactive and stable anode materials toward MeOH. Ni has gained attention as it is an alternative to noble atoms. In this study, Ni was deposited on reduced graphene layer which functionalized with S atoms via the hydrothermal method. The fabricated sample was characterized by using Scanning Electron Microscopy (SEM), Energy Dispersive X-ray Spectroscopy (EDX), mapping, X-ray Powder Diffraction (XRD), and Brunauer–Emmett–Teller method (BET). Two samples as called Ni/GCE and Ni@s-rGO/GCE were examined for methanol oxidation reaction in alkaline media. For methanol oxidation, due to the higher surface area, and small particle size of Ni, the mass activity of Ni@s-rGO/GCE is two times higher than Ni/GCE

Authors: Gök Özgül
Published: December 2023

In this study, photothermal effect by doping expanded graphite (EG) to smart nanofibers produced by electrospinning method was investigated. Fourier transform infrared (FT-IR) spectroscopy was exploited for chemical characterization. Thermal analysis experiments were carried out by heating and cooling curves. Surface morphology of the produced materials was investigated through scanning electron microscope (SEM). Contact angle was determined through contact angle measurement device. The appearance of the peak of the characteristic cyano group in the structure of Polyacrylonitrile (PAN) at 2237.02 cm-1 in the nanofibers having different percentages synthesized with EG and PAN was accepted as the evidence of PAN nanofibers formation. The temperature platforms in the heating/cooling curves exhibited that the temperature of the PAN and cellulose acetate (CA) nanofibers mixed with different EG percentage have higher than pristine nanofibers. The surfaces of the EG@PAN and EG@CA nanofibers were homogeneously distributed fibrous, excessive EG heterogeneously dispersed or electrosprayed in shape. The maximum contacts angles were measured as 67.96° and 52.88° for nanofibers synthesized with EG@CA and EG@PAN, respectively. As the result, the temperature of the nanofibers mixed EG at different percentages increased resulting from having the higher thermal conductivity of EG. Main goal of the study is both investigating photothermal effect in PAN and CA electrospun nanofibers doped with EG of activating heat accumulation property of the produced smart nanofibers for heat energy production from the solar. Thus, it will be possible to develop a new promising method in the production of the smart textile products that have the storage capacity of the solar energy.

CdTe solar cells on ultra-thin glass substrates are light and flexible. Flexible cells are widely preferred modules in technological fields. The flexibility of these cells enables them to cope with deformations. The efficiency of these has reached 19%. In this work, we used artificial neural network (ANN) method for the determination the performance of flexible CdTe solar cells despite bending and time. The performances of the solar cell before and after bending have been predicted. According to the results from the ANN calculations using the experimental data in the literature, MSE values of ANN estimates range from 0.06% to 0.28%.

On Deferred Statistical and Strong Deferred Cesàro Convergences of Sequences With Respect to A Modulus Function
Authors: Belen Cemal , Yıldırım Mustafa
Published: December 2023

Let f be any modulus function. We prove that the classes of strongly deferred Cesàro convergent sequences defined by f and deferred statistical convergent sequences are equivalent if the sequence is f-deferred uniformly integrable. Some converse inclusions are obtained when the modulus function f is compatible. Finally, for any compatible modulus f, we prove that any sequence is f-strongly deferred Cesàro convergent if and ony if it is deferred f-statistically convergent and deferred uniformly integrable.

Authors: Joha Zıad , Ergül Mustafa
Published: December 2023

Previous studies have reported the anticancer properties of β-glucan on various cancer cells. The objective of this research was to investigate the involvement of apoptosis in the cytotoxic action of β-glucan on the A549 cells. The cytotoxic impact of this drug on A549 cells was examined by subjecting them to various quantities of the substance, and the XTT assay was utilized to determine cell survival. Flow cytometry was performed to investigate apoptosis. A statistically significant and dose-dependent cytotoxic impact on A549 cells was observed upon treatment with β-glucan. The calculated IC50 value of β-glucan for A549 cells after a 24-hour treatment period was discovered to be 82.16 μg/mL. Further investigations carried out using the IC50 dose of β-glucan revealed a significant increase in the late apoptotic cells percentage. The capacity of β-glucan to trigger apoptosis is thought to be the cause of its cytotoxic action on lung cancer. The revelation of this discovery emphasizes the promising possibilities of β-glucan as an effective therapeutic choice.
A Novel Triazolopyrimidinone Derivative: A Portable Electrochemical Approach to Investigate DNA Interactions
Authors: Çetin Arif Engin
Published: December 2023

In this study, a novel triazolopyrimidinone derivative, 2-(2-chlorophenyl)-5-(morpholinomethyl)-[1,2,4]triazolo[1,5-a]pyrimidin-7(3H)-one, abbreviated as CPD-1, was synthesized as a drug candidate. By employing electrochemical techniques, we analyzed the electrochemical behavior of this compound and its interactions with both single-stranded DNA (ssDNA) and double-stranded DNA (dsDNA). Experimental parameters such as pH, concentration, scan rate, immobilization time were studied using Differential Pulse Voltammetry (DPV) and Cyclic Voltammetry (CV) to obtain the most precise analytical signals. We present an innovative approach to evaluate the toxicity effect of this drug candidate on DNA. We also propose a simplified equation to quantify toxicity effects based on changes in electrochemical signals, specifically peak current of guanine bases, before and after drug-DNA interactions. Our methodology contributes to the burgeoning field of electrochemical toxicity assessment and holds promise for advancing drug development and safety evaluation. Furthermore, stability tests for the drug candidate were conducted on different days. Notably, our investigation revealed significant alterations in guanine bases upon the interaction of CPD-1 with both ssDNA and dsDNA, underscoring the potential impact of these compounds on DNA structure. Based on our experimental data, we conclude that this molecule can be utilized as a drug due to its effects on DNA.

Published: December 2023

Stuttering; is defined as a deterioration in the fluency and timing of speech that can occur at any age, and which is inappropriate to the individual’s age and language skills. Several factors play a role in its etiology. Medications are one such factor. Atomoxetine is a drug that is frequently employed and well- tolerated in the treatment of attention-deficit hyperactivity disorder in children and adolescents. Stuttering is not a common side- effect when using atomoxetine. This report describes, a seven-year-old patient whose stuttering worsened significantly during atomoxetine use. This case is reported due to the scarcity of cases in which stuttering worsened during the use of atomoxetine.

Published: December 2023

Otogenic brain abscess, precipitated by acute mastoiditis, is a rare but potentially fatal condition. It constitutes an intracranial complication that can further develop due to meningitis and sigmoid sinus thrombosis. This case underscores the critical importance of early detection and therapeutic intervention, which often pose substantial clinical challenges. This report elucidates the case of a 35-year-old female who arrived with severe otalgia, noted predominantly on the right side, coupled with discharge and vertigo. Subsequent neuroimaging unveiled the presence of basal meningitis in the right cerebellar hemisphere, accompanied by an extradural abscess and coalescent mastoid air cells. The patient's treatment protocol entailed a rigorous antibiotic regimen, continually adjusted based on symptomatic improvement. The rapid diagnosis and immediate treatment of otogenic brain abscesses are paramount. As observed in our case, factors such as limited medical knowledge, oversight in medical care, and socio-economic disadvantages contributed to the severity of the intracranial complication. These elements highlight the necessity of addressing systemic factors in healthcare to ensure effective prevention and management of such conditions.
Hadis Münekkitlerinin Değerlendirmesinde Bir Hanefi Âlim: Yusuf B. Halid Es-Semtî
Authors: ORUÇHAN Osman
Published: December 2023

Yusuf b. Halid es-Semtî, Hicrî 189’da Basra’da vefat etmiştir. Gençliğinde Basra’da çeşitli âlimlerinden dersler almıştır. Sonra Kûfe’ye gitmiş, orada Ebû Hanîfe’den iki buçuk yıl kadar ders almıştır. Ardından Basra’ya dönerek Ehl-i Re’y usulüne göre ders vermeye başlamıştır. es-Semtî, bu tercihinden dolayı, Ehli Hadîs’in dışlamasına ve ötekileştirmesine maruz kalmıştır. Bu makalede es-Semtî’nin ilim hayatı ve güvenilirliği terâcim (biyografi) ve tabakât kitaplarından tespit edilmeye çalışılmıştır. Onun hadisleri de hadis kaynaklarından çıkarılarak değerlendirilmiştir. Araştırmamızda es-Semtî’nin hayatının önemli bir kısmında Ehl-i Re’y ve Ehl-i Hadîs’e mensup pek çok hadis râvîsiyle ilişkide bulunduğu görülmüştür. Onun rivayet ettiği hadislerin bazı temel hadis kaynaklarında yer aldığı görülmüştür. Hakkındaki cerhlerin kaynakları kronolojik olarak değerlendirilmiş ve Semtî’ye yönelik olarak yapılan cerh faaliyetlerinin, onun hadislerini uydurma kategorisinde değerlendirmeye neden olacak kadar ciddi oldukları görülmüştür. Makalemizde bu iddiaların kaynakları kronolojik olarak değerlendirilmiş ve bunların mezhep taassubundan kaynaklandığı delilleriyle ortaya konulmaya çalışılmıştır.
