On the finds of provincial Roman fibulae on the territory of Belarus
Authors: Beliavets Vadzim 
Published: February 2025

Abstract
The article presents fibulae of provincial Roman origin from museum collections of the Republic of Belarus. They are relatively few in number and originate primarily from the southwestern regions of the country. The typological series of these fibulae is generally characteristic of similar imports that circulated in Central Europe, various regions of Sarmatian settlement, as well as in the circle of broadly understood Balt cultures. Their general dating covers the entire Early Roman and the beginning of the Late Roman period. Observations on the typology and distribution pattern of imported Roman fibulae contribute to the analysis of the connections of the population of present day Belarus within Barbaricum. Analysis of these finds creates new opportunities for synchronizing the Belarus antiquities from Roman times with the chronology of neighbouring cultures of Central Europe and the Baltic region. It also allows us to change our understanding of the role of the population of Belarus in the formation and distribution of artefacts from the “barbarian enamels” horizon.

Authors: Moreira José , Schimanski Silvana 
Published: February 2025

O objetivo geral deste trabalho é contextualizar Guiné Bissau no âmbito do regime multilateral de comércio, institucionalizado pela Organização Mundial de Comércio (OMC). A adesão do país ao regime multilateral de comércio, prevê sua vinculação ao seu conjunto normativo relacionado à liberalização da política comercial. Os regimes internacionais são compreendidos na literatura de política internacional como um conjunto de princípios, normas, regras e processos de tomada de decisão que orientam o comportamento dos Estados. Por meio da abordagem qualitativa, da análise de conteúdo de fontes primárias e secundárias busca-se responder à seguinte pergunta: qual a situação de Guiné Bissau no âmbito do regime multilateral de Comércio? Apesar da adesão ao conjunto de princípios e normas da OMC, que prevê regras diferenciadas para a implementação dos compromissos assumidos por países menos desenvolvidos, o estudo concluiu que os desafios políticos domésticos impactam aspectos relacionados à política comercial do país.
Między fenomenologią a religijną metafizyką: poznanie i piękno w myśli Simone Weil
Authors: Stanekzai Ilias 
Published: February 2025

Celem niniejszego artykułu jest prezentacja filozoficznych fundamentów myśli Simone Weil poprzez analizę jej tekstów poświęconych pojęciom oderwania, wartości i „czytania”. Mimo że znajdujemy w tych tekstach raczej szkic i wstępny zarys niż spójną teorię filozoficzną, czytane razem stanowią całość i rzucają światło na problem poznania ludzkiego i sensu filozofii. Ukazana została ciągłość pomiędzy refleksją filozoficzną, inspirowaną Kantem i Alainem a religijnym wymiarem myśli Weil, w którym ważną rolę odgrywa piękno świata rozumiane jako akceptacja konieczności, która tym światem rządzi.
Ojkofobia, postmodernizm i konserwatyzm wobec zmian kulturowych i religijnych. Kilka refleksji w oparciu o myśl Rogera Scrutona
Authors: Duk Andrzej 
Published: February 2025

Poszukiwania wszelkich nowych rozwiązań w życiu indywidualnym, społecznym, a nawet religijnym stanowią dziś niezwykle częste zjawiska. W sposób oczywisty rodzą się zatem nowe sposoby myślenia i postawy z nich wypływające, dotyczące każdej dziedziny naszego życia. Na szczególną uwagę powinny zasługiwać te z nich, które pod pozorem naturalnie zmieniającego się świata próbują administracyjnie i autorytarnie kruszyć zastane schematy myślenia i działania osób oraz narodów, a które klasycznie można określić mianem konserwatywnych. Zarówno pojawienie się tez postmodernistycznych, jak i postawy ojkofobiczne (termin utworzony przez brytyjskiego filozofa Rogera Scrutona) należy zaliczyć do tych typów myślenia i działania, które próbują odgórnie zmieniać rzeczywistość. Jednak, jak wynika, między innymi z ewolucyjnie pojmowanej myśli konserwatywnej, wszelkie zmiany wprowadzane w taki sposób nie przyczyniają się do prawdziwego postępu jednostek i narodów. Pojawia się za to chaos i niezrozumienie. Analizy porównawcze przeprowadzone w niniejszym artykule próbują ukazać niektóre niepokonywalne różnice pomiędzy złudnym pragnieniem szybkich i dogłębnych zmian a prawdziwym, czyli ewolucyjnym rozwojem. Wskazują także na, często dziś zapominane, obiektywne i trwałe fundamenty naszego życia osobistego, społecznego, narodowego oraz religijnego.
Krótki traktat o wierchowaniu. Przyczynek do filozofii gór Józefa Tischnera
Authors: Sierotowicz Tadeusz 
Published: February 2025

Artykuł traktuje o „wierchowaniu”, czyli chodzeniu po górskich szczytach (wierchach). Ten ostatni, „locus ad quem” wspinaczki, symbol o wielorakim znaczeniu, jest widziany jako metafora o podwójnej wymowie: eschatologicznej i poznawczej. Interpretację metafory szczytu poprzedza refleksja dotycząca sposobu, w jaki konkretyzuje się myślenie właściwe filozofii gór. Zejściu z gór poświęcono podsumowanie.
Artificial intelligence: asking about its ontological status
Authors: Hołub Grzegorz 
Published: February 2025

The article deals with the ontological status of AI. Is this a person or a thing or maybe an entity between the human and material worlds? The concept of borderline person is considered as to a possible conceptual place to adopt AI and its future realizations. The concept of the borderline person was originally coined in bioethical research with an application to higher animals. In the post-Lockean understanding of the person the borderline person is an inclusive term and it leads to treating AI as if it were a person. In the post-Boethian philosophy of the human person, the borderline person has a negative character and acts as an excluding term; it maintains AI and all its incarnations as a highly developed tool, which maybe reaches the borders of the human world but never enters it. Practical predictions about the applicability of AI suggest that the latter approach is more appropriate.

Published: February 2025

A new glaserite-like ternary molybdate KZn0.5Hf0.5(MoO4)2 was obtained through a solid-state reaction, and its structure was refined using the Rietveld method. It was found that the compound crystallizes in the trigonal space group P m1 and melts at 656 °C with decomposition. At elevated temperatures, the compound exhibited significant ionic conductivity, reaching 0.39·10–3S/cm at 570 °C with an activation energy Еа = 1.0 eV, with oxygen ions as the probable charge carriers. The infrared spectrum simulated using DFT showed good agreement with experimental data, containing characteristic stretching modes of the MoO4 tetrahedra. The observed negative thermal expansion in the ab plane did not result in a reduction in the volume of the unit cell, with αV = 98∙10–6 °С–1 at 500 °С, indicating that KZn0.5Hf0.5(MoO4)2 can be classified as a material with high thermal expansion properties.

Published: February 2025

ST6 β-galactoside α2,6-sialyltransferase 1 (ST6GAL1), a crucial enzyme for tumor-associated sialic acid modification, has been reported to positively correlate with colorectal cancer (CRC) tumorigenesis; however, the underlying mechanism remains unclear. To elucidate the protumor mechanisms of ST6GAL1, we performed transcriptomic and N-glycoproteomic analyses and in vitro assays. We found that ST6GAL1 was significantly upregulated in tumor samples than in matched normal samples by analyzing fresh clinical samples from public databases (mean mRNA expression level: tumor vs. normal samples = 0.002712:0.000966, P < 0.05, n = 22). The in vitro results revealed that ST6GAL1 overexpression promoted CRC cell proliferation, migration, and chemoresistance, which were significantly blocked by its knockdown. Transcriptomic data showed that many genes related to the four modules (proliferation/cell cycle, migration, motility, and epithelial–mesenchymal transition (EMT) were upregulated after ST6GAL1 overexpression but downregulated after ST6GAL1 knockdown. Furthermore, the N-glycoproteome data revealed that 25 substrates that were sialylated upon ST6GAL1 overexpression were related to protumor activity. Importantly, we found that knockdown of lectin galactoside-binding soluble 3-binding protein (LGALS3BP), a newly identified secreted substrate of ST6GAL1, significantly blocked the proliferation, invasion, and chemoresistance of CRC cells induced by ST6GAL1 overexpression. Treatment with sialidases (neuraminidases, NAs) also blocked the protumor activity of ST6GAL1. Thus, ST6GAL1-induced increased sialylation of substrates, such as LGALS3BP and upregulation of protumor genes promote CRC tumorigenesis and chemoresistance, which provides important perspectives and new targets for the treatment of CRC.

Background: To compare intrathecal sequential plain and hyperbaric Bupivacaine with fentanyl and hyperbaric Bupivacaine with fentanyl for hemodynamic stability, onset of block and duration of block in patients undergoing caesarean delivery under spinal anesthesia.
Methods: This observational, double-blind study, seventy full term parturient, randomly divided to receive either 10 mg 0.5% Hyperbaric Bupivacaine with 25µg Fentanyl or 5 mg each of 0.5% plain and hyperbaric bupivacaine with 25 µg of Fentanyl. Surgery was allowed to proceed when block height reaches T6. Hemodynamic parameters, ephedrine use, time to reach peak dermatomal level and duration of sensory and motor block were compared among two groups.
Results: Demographic data, quality of perioperative anesthesia, Apgar score were identical in both groups. Incidence of Hypotension in HB (77.14%) as compare to 25.71% in PHB. Nausea/Vomiting in both the groups, 68.57% for HB and 25.71% for PHB. For HB, 80% (10.3mg) of patients required Ephedrine while 17 % (4mg) in Group PHB. Peak dermatomal level in minutes was faster in HB (06±1.13) as compare to PHB. (9.06±0.76) Maximum Block level was achieved in HB was T4.94±0.76 and in PHB it was 5.71±0.86. Time to regression of sensory block in minutes for HB was 234.86±10.49 and PHB 258.14±12.37. Recovery from motor block is faster in HB (190.66±10.38) compared to PHB (205.71±11.95).
Conclusions: Sequential administration of low dose of hyperbaric and plain bupivacaine with fentanyl provides better hemodynamic stability, accomplish adequate level of sensory and motor block in obstetric population for caesarean delivery.
Frictional resistance of low hysteresis superelastic orthodontic archwires after different metal oxide nanocoatings
Authors: Srinivasan Dilip , Krishnan Rajkumar 
Published: February 2025

To compare the frictional resistance between uncoated and nanocoated low-hysteresis superelastic orthodontic archwires using three metal oxides: Aluminium oxide, titanium oxide, and zirconium oxide, when used with metal and ceramic orthodontic brackets.A total of 120 segments of Low-hysteresis superelastic NiTi archwires (Tomy Orthodontics, Japan) measuring 25 mm, were divided into eight groups: uncoated, Al₂O₃-coated, TiO₂-coated, and ZrO₂-coated. Each group having 30 segments which were further divided into two subgroups of 15 each; for testing with metal and ceramic brackets. The nanocoatings were applied using a dip-coating method, followed by heat treatment to ensure adhesion. For frictional testing, upper premolar MBT prescription metal and ceramic brackets with 0.022-inch slots (Ormco, Brea, CA, USA) were mounted on a customised jig with a fixed interbracket distance. The archwires were tested individually by threading them through the brackets, and frictional resistance was measured using a universal testing machine at a sliding rate of 2 mm/min under dry conditions for a duration of one minute. Mean frictional values were recorded in N and then paired t test andANOVA with Tukey’s Post hoc LSD tests were done for comparison.The results showed that the uncoated wire with ceramic bracket showed the highest friction (21.9687 N) and the least friction was found with ZrO₂ coated wires with metal bracket (3.1253 N). Among the nanocoatings, the ZrO₂-coated wires demonstrated the lowest frictional resistance, followed by TiO₂ and Al₂O₃ coatings. Frictional resistance was significantly higher with ceramic brackets compared to metal brackets across all wire types, but the nanocoatings significantly reduced friction in both bracket types.Metal oxide nanocoatings on low-hysteresis superelastic archwires significantly reduce frictional resistance, with zirconium oxide providing the most substantial reduction. These findings suggest that nanocoated wires, especially with ZrO₂, may enhance the efficiency of orthodontic treatments by minimizing frictional forces

Conventional lateral cephalograms utilize two-dimensional (2D) technology, which limits the information retrieved from the scan. The accuracy and reliability with 3D superimpositions, offer a useful method for evaluating orthodontic treatment changes, as well as growth in patients. Cephalometric evaluation lacks a defined gold standard and Traditional methods face errors and time issues, while digital approaches vary in efficiency. This study aimed to evaluate and compare the accuracy of manual, digital and CBCT-generated superimposition of cephalometric landmarks.The study consisted of 20 patients wherein two lateral cephalograms and two CBCT were taken for each patient. They were traced manually/digitally at the beginning and one-year intervals. Reference landmarks marked on the anterior cranial base, maxilla, and mandible for superimposition of radiographs and CBCT. Radiographic tracings were superimposed manually, digital superimposition done with DOLPHIN software for radiographs and INVIVO SOFTWARE for CBCT scans. Subsequently, these superimpositions were compared for accuracy.Maxillary and mandibular measurements showed improved 3D accuracy over manual and 2D methods in both the X and Y axes. Dentition measurements significantly improved in 2D and 3D compared to manual. Soft tissue measurements in 3D surpassed both manual and 2D, with no significant difference from 2D for mean soft tissue measurements.Compared to manually and digitally traced radiographs, all evaluated procedures were acceptable and dependable. The CBCT scans provided higher levels of accuracy and reliability.

Orthodontic treatment relies heavily on accurate diagnosis and treatment planning. Traditionally, study casts obtained from plaster models have been an essential component of orthodontic records. However, advancements in three-dimensional imaging and modeling have introduced digital alternatives, offering ease of access, storage, and transfer of patient information. To compare the accuracy of linear measurements obtained from 3D printed models with those taken from plaster study models and identify the most reliable type of printed model. The study was conducted on ten patients requiring fixed orthodontic treatment. Dental impressions were scanned using laser desktop scanners and intraoral scanning of patients maxillary dentition, and then resulting images were converted to stereolithography (STL) format for 3D printing. Linear measurements, including tooth size and arch width, were taken using a digital caliper on plaster, intraoral, and laser scanned printed models. Statistical analysis revealed no significant differences in tooth size and arch width measurements between plaster models and both types of 3D printed models (intraoral and laser scanned). The average differences in mesio-distal width measurements were found to be within clinically acceptable ranges. Three-dimensional imaging and 3D printing technologies have revolutionized orthodontics, providing accurate and reliable digital alternatives to traditional plaster models. The study findings support the use of 3D printed models for orthodontic diagnosis and treatment planning, indicating their potential to replace plaster models in the future.

: This research assessed and contrasted the leaking of possibly hazardous polymers that leach after commonly used orthodontic materials.: The study assessed three groups Adhesives, retainers, and elastomeric chains ligating rings. A diagnostic solution was arranged with 1.6 mg potassium permanganate (ACS reagent grade, 99%) added to 1L of concentrated water. The study included three trials. In trial 1, samples were immersed in 5 ml of potassium permanganate solution. In trial 2, the solution was adulterated with distilled water in a 1:3 ratio. In trial 3, acid was supplementary to the solvent to lower the PH to 1, and samples from all groups were immersed.A digital camera was used to snap samples for color changes over time.Each fresh sample was tested over ten days. The faster discolouration indicated greater leaching. Results were anatomized using SPSS interpretation 11 and the Chi-square test, with a P-value of lower than 0.05 measured statistically notable. Rely-a-bond(no- blend) tenacious percolated significantly further polymer than Transbond XT adhesive after 8 hours. Self-cure acrylic, Bioplast sheets, and elastomeric chains from Ortho- organizer and Ormco also percolated polymers.The “ Do- it- yourself ” tests effectively indicated polymer filtering, abetting manufacturers in optimizing products and clinicians in choosing safer options. The short- term threat of estrogenic goods from BPA- grounded resins is inconsequential.
The Economics of Shadow Economy in Real Estate: The Case of Greece
Authors: Stasinopoulos D. , Kastanioti C. 
Published: February 2025

The paper attempts to measure and report the extent and magnitude of Shadow Economy in Real Estate in Greece. The present research analyzed the sale prices of residential real estate for the years 2018 and 2022. In the first phase, the sale price per square meter was determined for the houses for sale, in particular apartments and detached houses, through websites of real estate ads for sale. In the second phase, the average sale price per square meter was determined for the same years, through the analysis of sales contracts as they are recorded in detail in the application of the Greek Ministry of Finance, the "Register of Real Estate Transfer Values". The comparison that followed showed that the percentage difference between these two figures is related to the shadow economy. From 2018 to 2022, the shadow economy in real estate shows a clear trend of decline, although it is still high. From 49.38% estimated to hide the real sale value in 2018, it decreased to 39.48% in 2022, not counting any discounts made. In 2018 the amount of the declaration of actual sales values was estimated at € 614.6 million and in 2022 at € 728.7 million.
At the same time, a quantitative survey was conducted on a random sample of 715 people in order to estimate the percentage of achieving a discount between the buyer and seller with a period of the last five years. The conclusion is that the discount rate in the majority ranges up to 5% especially in recent years, while rates up to 10% are noted on old properties. The above amount of deduction must be taken into account for the final determination of the estimated shadow economy in the real estate market.
Also identified were those properties that were sold with a significant difference from their objective value, i.e. over € 100,000.00 and over € 200,000.00, an important indication for "laundering" non-taxable and / or dirty money. In 2018, money laundering was estimated at €192.5 million to €231 million and in 2022 at €227 million to €303 million.

New Method for Nuclear Magnetic Resonance Dual Echo Time Logging Interpretation and Fluid Identification in Tight Sandstone Gas Reservoirs
Authors: Li Bo , Yin Guofeng , Wang Anlong , Tan Maojin 
Published: February 2025

Summary
For tight sandstone gas reservoirs, conventional logging has great uncertainty, and fluid identification is difficult. Nuclear magnetic resonance (NMR) dual echo time (TE) logging has good application potential in identifying tight sandstone gas layers. The original NMR logging spectrum and diffusion analysis (DIFAN) methods both assume that the diffusion coefficients of gas and water are known and reflect gas information. However, the existing methods cannot be applied to complex gas layers. In this paper, we propose a new NMR dual TE logging interpretation method combining particle swarm optimization (PSO) with least squares (LSQR) algorithm inversion. Based on the principle of NMR dual TE logging activation, we analyze its relaxation mechanism and derive the equations between the echo train amplitude difference and fluid type, fluid content, and fluid diffusion coefficient. Based on the PSO inversion method, we perform nonlinear inversion of the constructed objective function to obtain parameters, such as the diffusion coefficient of the fluid, and generate an echo train difference that reflects the fluid information. We then use the LSQR method to invert the generated echo train differences to obtain a difference spectrum that reflects hydrocarbon information, and then calculate the gas volume and gas saturation of the reservoir’s flushed zone. We verify the correctness of the new method by building a rock model and conducting numerical simulations. Based on the calculation results, the gas-containing porosity in the flushed zone calculated by the new method and the gas-containing porosity in the flushed zone calculated by the time domain analysis (TDA) method crossplot are constructed. We applied the above method to the Huagang formation in a basin in eastern China. The results show that this idea and the inversion method can effectively realize the NMR dual TE logging data processing of tight sandstone gas reservoirs, and the fluid identification crossplot established based on the processing results improves the accuracy of gas layer identification.
