Authors: Kim Yoosuk , Kuljanishvili Irma
Published: October 2023

Carbon nanotubes (CNTs) have gained significant attention in the scientific and technology sectors due to their exceptional physical, chemical, and electronic properties. These qualities make them excellent candidates for several electronic applications, such as ballistic conduction, high current densities, low power consumption, outstanding single-photon capacity, and excellent nano-mechanical resonators. However, incorporating CNTs into specific micro- and nano-architectures and hybrid structures remains challenging. Developing fabrication and patterning technologies, involving CNTs, that can scale up while utilizing their exceptional properties has received significant attention in the last two decades. Various approaches have been investigated, including top-down and bottom-up methods, and new techniques have been used to achieve selective CNTs production through patterning. The continued developments of patterning technologies is critical for fully exploiting CNTs’ practical applicability. This mini-review looks at recent advances in fabrication and patterning of CNTs with micro- and nanoscale resolution, such as using pre-patterned substrates, dielectrophoresis, oxidative etching, and selective production and growth for CNTs, or direct printing of CNT-containing inks, etc. Article discusses advantages and limitations of various approaches for achieving accurate and scalable CNT patterning. Overcoming fabrication challenges will pave the way for a widespread use of CNTs in various applications including electronics, photonics, mechanical and biomedical devices and hybrid systems, etc.

Published: October 2023

Introduction

Climate change and the fast pace of urbanization are two major factors contributing to the exacerbated risk of flooding in urban areas. Flood resilience strategies, underpinned by the principles of green infrastructure, are gaining importance as within broader spatial planning approaches, and various global cities are adopting revised policies and frameworks to improve flood risk management. Yet, such responsive approaches are still limited and context-specific.

Methods

In this article, thematic analysis using NVivo was employed to analyse 49 documents related to flood risk management, resilience, and green infrastructure planning.

Results

This paper reflects on the concepts of flood risk management, flood resilience and green infrastructure planning to identify the synergies between these concepts, and identify challenges that are prohibiting global flood resilience.

Discussion

Enhancing flood resilience requires coordinated efforts, effective communication, and collaborative governance among stakeholders. The paper also draws planning recommendations for advancing flood resilience through governance and an integrated planning approach, in support of the global goals toward flood resilience.
Manifold Explorer: Satellite Image Labelling and Clustering Tool with Using Deep Convolutional Autoencoders
Authors: Patel Tulsi , Jones Mark W. , Redfern Thomas
Published: October 2023

We present a novel approach to providing greater insight into the characteristics of an unlabelled dataset, increasing the efficiency with which labelled datasets can be created. We leverage dimension-reduction techniques in combination with autoencoders to create an efficient feature representation for image tiles derived from remote sensing satellite imagery. The proposed methodology consists of two main stages. Firstly, an autoencoder network is utilised to reduce the high-dimensional image tile data into a compact and expressive latentfeature representation. Subsequently, features are further reduced to a two-dimensional embedding space using the manifold learning algorithm Uniform Manifold Approximation and Projection (UMAP) and t-distributed Stochastic Neighbour Embedding (t-SNE). This step enables the visualization of the image tile clusters in a 2D plot, providing an intuitive and interactive representation that can be used to aid rapid and geographically distributed image labelling. To facilitate the labelling process, our approach allows users to interact with the 2D visualization and label clusters based on their domain knowledge. In cases where certain classes are not effectively separated, users can re-apply dimension reduction to interactively refine subsets of clusters and achieve better class separation, enabling a comprehensively labelled dataset. We evaluate the proposed approach on real-world remote sensing satellite image datasets and demonstrate its effectiveness in achieving accurate and efficient image tile clustering and labelling. Users actively participate in the labelling process through our interactive approach, leading to enhanced relevance of the labelled data, by allowing domain experts to contribute their expertise and enrich the dataset for improved downstream analysis and applications.
Gynecological Healthcare: Unveiling Pelvic Masses Classification through Evolutionary Gravitational Neocognitron Neural Network Optimized with Nomadic People Optimizer
Authors: Deeparani M. , Kalamani M.
Published: October 2023

Accurate and early detection of malignant pelvic mass is important for a suitable referral, triage, and for further care for the women diagnosed with a pelvic mass. Several deep learning (DL) methods have been proposed to detect pelvic masses but other methods cannot provide sufficient accuracy and increase the computational time while classifying the pelvic mass. To overcome these issues, in this manuscript, the evolutionary gravitational neocognitron neural network optimized with nomadic people optimizer for gynecological abdominal pelvic masses classification is proposed for classifying the pelvic masses (EGNNN-NPOA-PM-UI). The real time ultrasound pelvic mass images are augmented using random transformation. Then the augmented images are given to the 3D Tsallis entropy-based multilevel thresholding technique for extraction of the ROI region and its features are further extracted with the help of fast discrete curvelet transform with the wrapping (FDCT-WRP) method. Therefore, in this work, EGNNN optimized with nomadic people optimizer (NPOA) was utilized for classifying the gynecological abdominal pelvic masses. It was executed in PYTHON and the efficiency of the proposed method analyzed under several performance metrics. The proposed EGNNN-NPOA-PM-UI methods attained 99.8%. Ultrasound image analysis using the proposed EGNNN-NPOA-PM-UI methods can accurately predict pelvic masses analyzed with the existing methods.
The Impact of the COVID-19 Pandemic, Transport Accessibility, and Accommodation Accessibility on the Energy Intensity of Public Tourist Transport

Published: October 2023

The article concerns the recognition of the impact of the COVID-19 pandemic, transport accessibility, and accommodation availability on the energy intensity of domestic travel by tourists using public transport in spatial and dynamic relations. The article formulated five research questions: (1) Does the improvement of transport accessibility reduce the energy intensity of public tourist transport? (2) Does the improvement of accommodation availability affect the reduction of the energy intensity of domestic tourist trips of Polish residents? (3) Has COVID-19 significantly changed the energy intensity of public tourist transport? (4) Are there any spatial effects of energy intensity of domestic tourist trips of Polish inhabitants resulting from the flow of tourists between regions (voivodeships) of Poland? (5) What would be the path of energy intensity patterns of public tourist transport if fortuitous events did not occur? The study covered 16 Polish voivodeships in 2017–2021. A comprehensive approach was used, combining exploratory analysis of spatial data with regional econometrics, spatial statistics, and spatial econometrics (gravitational model of spatial convergence of energy intensity of public transport of tourists). It has been verified that the energy intensity of domestic tourist travel by public transport is the most sensitive to the effects of the COVID-19 pandemic and the most flexible to changes in transport accessibility. It is less sensitive to changes in accommodation availability. The occurrence of spatial convergence, i.e., the blurring of differences in energy intensity patterns between the analyzed voivodeships, was also identified. An increase in energy intensity in voivodeships defined as neighboring voivodeships by 1% will result in an increase in energy intensity in the i-th voivodeship by 0.2688% on average, which results from the spatial effects of changes in mobility and tourist flows (tourism). Consumption patterns shaped in previous periods also have a significant impact on energy intensity.

Published: October 2023

Psoriasis is a chronic, complex, immunological disorder, which may lead to many different systemic complications. Sphingolipids, including ceramide, are bioactive lipids, which take part in the regulation of immune reactions, cell growth, and apoptosis. Twenty psoriatic patients and twenty-eight control subjects were included in the study. Skin (both lesional and non-lesional) and serum samples were collected from both the control group and the psoriatic patients. The levels of sphingosine (SFO), sphingosine-1-phosphate (S1P), sphingomyelin, sphinganine (SFA), sphinganine-1-phosphate (SFA1P), and ceramide (CER) were assessed in both tissue (t) and serum (s) samples using high-performance liquid chromatography (HPLC). We identified elevated serum levels of SFO, S1P, SFA, and SFA1P in psoriatic patients when compared to healthy individuals. As far as the lesional skin and serum of psoriatic patients are concerned, we demonstrated positive associations between CER_t and CER_s, SFA_t and CER_s, and SFO_t and CER_s. Additionally, we found negative correlations in the non-lesional skin and serum of psoriatic patients, including SFO_t vs. SFO_s, CER_t vs. SFA_s, CER_t vs. SFO_s, and SFO_t vs. SFA_s. Finally, we observed a positive correlation between S1P and SFA1P in both the serum samples of psoriatic patients and the serum samples of the control group. In this study, we did not observe any correlations between psoriasis area and severity index (PASI) scores and sphingolipid levels. In conclusion, our findings indicate an interplay between skin and serum lipids in psoriatic patients, which is not observed in healthy individuals.

Cannabidiol (CBD), the main non-psychoactive component of Cannabis sativa L., is widely used in therapy for the treatment of different diseases and as an adjuvant drug. Our aim was to assess the effects of CBD on proinflammatory cytokine production and cell proliferation in human peripheral blood mononuclear cells (PBMCs) and on CD4+ T lymphocyte differentiation, and, furthermore, to test CBD’s ability to affect the functional properties of regulatory T cells (Treg). Experiments were performed on isolated PBMCs and purified CD4+ T lymphocytes obtained from the buffy coats of healthy subjects. Cytokines produced by CD4+ T cells were evaluated by flow cytometry and intracellular cytokine staining techniques. PBMC cytokine production was measured by an ELISA assay. Real-time PCR was used to assess the mRNA expression of cytokines and the key transcription factors (TFs) of CD4+ T cells. Finally, the proliferation of PBMC and CD4+ T effector cells (Teff), alone and in the presence of Treg, was assessed by flow cytometry. Results showed that CBD affects both the frequency of IL-4-producing CD4+ and of IFN-γ/IL-17-producing cells and dramatically decreases the mRNA levels of all TFs. Stimuli-induced cytokine mRNA expression was decreased while protein production was unaffected. CBD was unable to affect the ability of Treg to prevent Teff cell proliferation while it slightly increased PBMC proliferation. In conclusion, CBD may inhibit the expression of proinflammatory cytokines; however, the effect of CBD on cell proliferation suggests that this cannabinoid exerts a complex activity on human PBMCs and CD4+ T cells which deserves further investigation.
The IGF1 Signaling Pathway: From Basic Concepts to Therapeutic Opportunities
Authors: Werner Haim
Published: October 2023

Insulin-like growth factor 1 (IGF1) is a peptide growth factor with important functions in multiple aspects of growth, development and metabolism. The biological actions of IGF1 are mediated by the IGF1 receptor (IGF1R), a cell-surface protein that is evolutionarily related to the insulin receptor (InsR). The effects of IGF1 are moderated by a group of binding proteins (IGFBPs) that bind and transport the ligand in the circulation and extracellular fluids. In mechanistic terms, IGF1R function is linked to the MAPK and PI3K signaling pathways. Furthermore, IGF1R has been shown to migrate to cell nucleus, where it functions as a transcriptional activator. The co-localization of IGF1R and MAPK in the nucleus is of major interest as it suggests novel mechanistic paradigms for the IGF1R-MAPK network. Given its potent anti-apoptotic and pro-survival roles, and in view of its almost universal pattern of expression in most types of cancer, IGF1R has emerged as a promising molecular target in oncology. The present review article provides a concise overview of key scientific developments in the research area of IGF and highlights a number of more recent findings, including its nuclear migration and its interaction with oncogenes and tumor suppressors.

Extracellular vesicles (EVs) contribute to osteoarthritis pathogenesis through their release into joint tissues and synovial fluid. Synovial fluid-derived EVs have the potential to be direct biomarkers in the causal pathway of disease but also enable understanding of their role in disease progression. Utilizing a temporal model of osteoarthritis, we defined the changes in matched synovial fluid and plasma-derived EV small non-coding RNA and protein cargo using sequencing and mass spectrometry. Data exploration included time series clustering, factor analysis and gene enrichment interrogation. Chondrocyte signalling was analysed using luciferase-based transcription factor activity assays. EV protein cargo appears to be more important during osteoarthritis progression than small non-coding RNAs. Cluster analysis revealed plasma-EVs represented a time-dependent response to osteoarthritis induction associated with supramolecular complexes. Clusters for synovial fluid-derived EVs were associated with initial osteoarthritis response and represented immune/inflammatory pathways. Factor analysis for plasma-derived EVs correlated with day post-induction and were primarily composed of proteins modulating lipid metabolism. Synovial fluid-derived EVs factors represented intermediate filament and supramolecular complexes reflecting tissue repair. There was a significant interaction between time and osteoarthritis for CRE, NFkB, SRE, SRF with a trend for osteoarthritis synovial fluid-derived EVs at later time points to have a more pronounced effect.

Published: October 2023

The synthesis of eleven new and previously undescribed benzamides was designed. These compounds were specifically projected as potential inhibitors of the enzymes acetylcholinesterase (AChE) and β-secretase (BACE1). N,N′-(1,4-phenylene)bis(3-methoxybenzamide) was most active against AChE, with an inhibitory concentration of AChE IC50 = 0.056 µM, while the IC50 for donepezil was 0.046 µM. This compound was also the most active against the BACE1 enzyme. The IC50 value was 9.01 µM compared to that for quercetin, with IC50 = 4.89 µM. Quantitative results identified this derivative to be the most promising. Molecular modeling was performed to elucidate the potential mechanism of action of this compound. Dynamic simulations showed that new ligands only had a limited stabilizing effect on AChE, but all clearly reduced the flexibility of the enzyme. It can, therefore, be concluded that a possible mechanism of inhibition increases the stiffness and decreases the flexibility of the enzyme, which obviously impedes its proper function. An analysis of the H-bonding patterns suggests a different mechanism (from other ligands) when interacting the most active derivative with the enzyme.
Decline of Empathy among Healthcare Apprentices
Authors: Razi Mohammed O. , Fouzia Rinat , Razzaque Mohammed S.
Published: October 2023

Empathy is a crucial human quality that enables healthcare professionals to connect with patients, providing physical and emotional support to enhance patient-centered care. Empathy in healthcare is critical for establishing patient-provider (healthcare) trust, increasing patient satisfaction, and, eventually, delivering high-quality healthcare. However, there is growing concern about the declining levels of empathy among healthcare providers, partly related to increased workload, burnout, and empathic distress fatigue. Moreover, the recent emphasis of medical education on the technical aspects of healthcare over empathetic care also contributed to the decline of empathy among healthcare providers with compromised patient care. This brief article summarizes the potential causes and consequences of declining empathy in medical practice with future implications on the quality of humanized healthcare.
Effect of Stacking Sequence on Mechanical Properties and Microstructural Features within Al/Cu Laminates
Authors: Kunčická Lenka , Kocich Radim
Published: October 2023

The study presents a method to prepare Al/Cu laminated conductors featuring two different stacking sequences using rotary swaging, a method of intensive plastic deformation. The primary focus of the work was to perform detailed characterization of the effects of room temperature swaging on the development of microstructures, including the Al/Cu interfaces, and internal misorientations pointed to the presence of residual stress within the laminates. The results revealed that both the Al and Cu components of the final laminates with 5 mm in diameter featured fine, more or less equiaxed, grains with no dominating preferential texture orientations (the maximum observed texture intensity was 2.3 × random for the Cu components of both the laminates). This fact points to the development of dynamic restoration processes during swaging. The analyses of misorientations within the grains showed that residual stress was locally present primarily in the Cu components. The Al components did not feature a substantial presence of misorientations, which confirms the dynamic recrystallization. Tensile testing revealed that the laminates with both the designed stacking sequences exhibited comparable UTS (ultimate tensile strength) of almost 280 MPa. However, notable differences were observed with regard to the plasticity (~3.5% compared to less than 1%). The laminate consisting of Al sheath and Cu wires exhibited very low plasticity as a result of significant work hardening of Al; this hypothesis was also confirmed with microhardness measurements. Observations of the interfaces confirmed satisfactory bonding of both the metallic components.

Published: October 2023

Following the work already carried out in our laboratory on eucalyptol, a new green solvent derived from biomass, we are now looking at sabinene as another new green solvent. Sabinene is also derived from biomass, has no known toxicity and can be recycled by distillation. We have shown that it can be used as it is or distilled to synthesize thiazolo[5,4-b]pyridine heterocycles by thermal activation or microwave irradiation. This new solvent was compared with various conventional and green solvents. The conditions were optimised to enable us to carry out the syntheses in satisfactory yields, and we were able to show that sabinene, a natural bicyclic monoterpene, could be used effectively as a solvent.

Published: October 2023

Edaravone (EDA), an antioxidant drug approved for the treatment of ischemic stroke and amyotrophic lateral sclerosis, was recently proposed as a remyelinating candidate for the treatment of multiple sclerosis. Here, we synthesized twelve EDA analogues 2b–4c showing three substitution patterns A–C, searching for improved remyelinating agents and putative molecular targets responsible for their regenerative activity. We profiled them in three primary assays to determine their stimulation of oligodendrocyte progenitor cell metabolism (tetrazolium MTT assay), their antioxidant potential (2,2-diphenyl-1-picrylhydrazyl-DPPH assay) and to predict their bioavailability (virtual ADME profile). Active 4′-carboxylate 2b, 4′-ester 2c and N1-carbamate-4′-ester 4a were further characterized, justifying their in vitro effects and selecting 4a as a putative EDA 1 prodrug suitable for in vivo testing.

Published: October 2023

It has long been known that containers for sample analysis or storage can play a role in endotoxin recovery and have to be taken into account when determining endotoxin concentrations. However, there is little data on the effects of containers regarding (1→3)-β-D-glucan, which plays a role as a contaminant in endotoxin measurements. To determine the effect of the container on (1→3)-β-D-glucan measurements, four different types of containers were investigated at different temperatures and stored for up to 28 days. For short-term storage for 3 h at room temperature, no effect of the container on the (1→3)-β-D-glucan recovery could be observed, but for storage at −20 °C, the results indicate that the storage time and temperature influences (1→3)-β-D-glucan detection. All containers showed a trend of lower recoveries over time, but the polyethylene container showed a significantly lower recovery compared to the other containers. We also showed that freeze/thaw cycles had a strong influence on the recovery of (1→3)-β-D-glucan in polyethylene containers. Our study showed that the container can affect not only the detection of endotoxins but also the detection of (1→3)-β-D-glucans.

Authors:   Korean Society of Nursing Research, Oh Eun Jung , Oh Young Ju
Published: October 2023

Purpose : The purpose of this study was to investigate moral sensitivity and their mediating effects on the relationship among facilitative communication, attitude toward caring and performing older adult care in geriatric hospital nurses.
Method : In total, 202 individuals participated in the cross-sectional study. Data were collected from August to October 2022 using structured questionnaires. The data were analyzed using multiple regression and a simple mediation model applying the PROCESS Macro with 95% bias-corrected bootstrap confidence interval( 5,000 bootstrap resampling).
Result : Older adult care performance was significantly associated with facilitative communication (r＝.88, p＜.001), attitude toward caring (r＝.76, p＜.001), and moral sensitivity (r＝.68, p＜.001). Using PROCESS Macro Model 4, care performance was found to be directly affected by facilitative communication (β＝.88, p＜.001) and attitude toward caring (β＝.76, p＜.001). Moral sensitivity was directly affected by facilitative communication (β＝.67, p＜.001) and attitude toward caring (β＝.75, p＜.001). The partial mediating effects of moral sensitivity (β＝.76, p＜.001, 95% confidence interval 0.06∼0.19) in facilitative communication’s impact on care performance and (β＝.57, p＜.001, 95% confidence interval 0.11∼0.38) on the impact of attitude toward caring on older adult care performance were confirmed.
Conclusion : The findings indicate that education strategies that can simultaneously increase facilitative communication, attitude toward caring and moral sensitivity are more effective when developing education programs that enhance the care performance of geriatric hospital nurses. Cultivating moral sensitivity will further promote geriatric hospital nurses' older adult care performance.

Published: October 2023

Purpose : This study was conducted to analyze the correlation between patient safety competencies, perception of patient safety culture, and safe nursing activities among intensive care unit (ICU) nurses, as well as to analyze the influencing factors related to these aspects.
Method : We used a cross-sectional design with a convenience sample of 141 working in the intensive care unit (ICU). Data collection took place from January 17, 2023, when it received IRB approval, to January 31, 2023. The collected data were analyzed using descriptive analysis, t-test(or Mann-Whitney test), ANOVA(or Kruskal-Wallis test), Pearson correlation coefficients, and multiple regression.
Results : The results of this study revealed that patient safety competency had the most significant impact on nurses' safety nursing activities (β＝.58, p＜.001). However, patient safety culture (β＝.12, p ＝.116) did not exhibit statistical significance. The overall explanatory power of the model was 43.4%.
Conclusion : Based on the findings of this research, it has become evident that the competency of nurses in patient safety exerts a crucial role in reinforcing safety-related nursing practices within intensive care units. To bolster this competency, it is imperative to implement educational programs or initiatives that accentuate knowledge, attitudes, and skills related to patient safety.

Published: October 2023

In this paper, a new generalization of the half-logistic distribution was introduced and called the ‘Odd Weibull Exponentiated Half-Logistic Distribution (OWEHLD)’. The OWEHLD was realized by using the Weibull distribution to transform the exponentiated half-logistic distribution using the quantile function of the log-logistic distribution or the odd ratio as link. This approach for generalizing the half-logistic distribution is the so-called ‘transformed-transformer approach’. Several mathematical properties of the OWEHLD were derived and studied and the maximum likelihood estimation method was employed in estimating its parameters. Real life data sets including a wind speed sample from Nigeria were further used to test the applicability of the new distribution.
An Analysis on the Cognitive Structure and Opinions of Pre-Service Science Teachers on the Concept of Micro Teaching
Authors: Demirci Tuba , Akgün Elif
Published: October 2023

In this study, it is aimed to examine the cognitive structures of pre-service science teachers regarding the concept of “micro teaching”. The study was carried out with 25 teacher candidates studying in the 4th grade of science teaching at Alanya Alaaddin Keykubat University Faculty of Education in a 4-week period within the scope of the teacher practice course in the fall semester of the 2021-2022 academic year. In the study, since it was aimed to reveal the cognitive structures of pre-service science teachers regarding the concept of “micro teaching”, screening method was used. In the collection of the study data, “independent word association test, drawing-writing and concept map” were used. Content analysis was performed in the analysis of the data obtained from the study. When the findings obtained as a result of the study were examined, the categories obtained from three different measurement tools had features that support and explain each other. “Part of micro teaching, teaching practice, self-assessment and tools used in micro teaching” obtained from all three measurement tools emerged as common and dominant categories. The most commonly used answer words by pre-service teachers for the category of “part of micro teaching” were determined as “pre-service teacher, planning, presentation, group work, lesson, student, teaching, information, education, registration, teaching, self-evaluation, class, re-teach and re-plan”. The most commonly used answer words for the category of “teaching practice” by pre-service teachers were determined as “skill, development, experience, technique, experimentation, performance, ability, observation, reducing anxiety and practice”. The most commonly used answer words by pre-service teachers for the category of “self-evaluation” were determined as “evaluation, review, feedback, monitoring and feedback”. The most common answer words used by teacher candidates for the category of “tools used in micro teaching” were determined as “video, camera and tape”. When the drawings made by the pre-service teachers for approximately micro teaching are examined according to the levels, the drawings of 50% of them are partial drawings and conceptual representative drawings. They explained the concept of micro teaching in ways related to scientific facts. This situation can be evaluated as the cognitive structures of pre-service science teachers related to the concept of micro teaching are sufficient.

This study investigates the extent to which paper-based data-driven learning (DDL) activities can improve Thai EFL students’ grammar learning of conditional sentences (the second condition), as well as the participants’ attitudes toward learning through the DDL approach. This was a two-week research using a one-group pre-test and post-test design. The convenience-sampled participants were 15 Thai EFL undergraduate students majoring in English at the Faculty of Humanities and Social Sciences. This study included three research instruments: a pre/post-test, an attitudes questionnaire, and interviews. The instructional approach, which consisted of the paper-based DDL material, was devised using The Corpus of Contemporary American English (COCA) consisting of 40 concordances. Using non-parametric statistics Wilcoxon Signed Rank Test, there is a statistically significant difference in mean scores in the findings (p<.001), indicating that their grammatical knowledge was developed after participating in DDL activities. Furthermore, the participants had positive attitudes towards DDL learning since they considered DDL as a fruitful and beneficial tool in helping them acquire grammatical knowledge and language patterns by themselves. Therefore, the outcomes of the research have a noteworthy impact on the field of teaching English, showcasing the potential of utilizing corpus data to analyze genuine language patterns and enhance learners’ understanding of language structure.

Published: October 2023

Bu çalışmada Orta Anadolu Bölgesi’nin Kapadokya bölümünde, Nevşehir il sınırları içerisinde yer alan Ovaören-Yassıhöyük’te tespit edilen Geç Demir Çağı tabakasının özellikle mimari gelenekleri üzerinden bir değerlendirme yapılması amaçlanmıştır. Geç Tunç Çağı ve Orta Demir Çağı’nda kentsel özellikleri barındıran unsurları ile öne çıkan yerleşimde çalışmalar 2007 yılında başlamış ve halen devam etmektedir. Bu dönemlerin aksine, şu ana kadar üç ana mimari ve alt evreleri ile tespit edilen Geç Demir Çağı tabakasından elde edilen veriler ise Ovaören’in Pers/Akamenid siyasi egemenliğinin yaşandığı dönemde kırsal karakterli bir merkeze dönüştüğünü göstermektedir. Bölgede verimli tarım arazilerine hâkim alanlarda kurulan yerleşmelerin seramik, mimari ve küçük buluntular özelinde benzer özellikler gösterdiği bilinmekle birlikte, Ovaören Geç Demir Çağı tabakasında tespit edilen yapı katları, yerleşimin söz konusu süreç içerisinde bir takım değişiklikler geçirdiğini açığa çıkarmıştır. Bu kapsamda kazı çalışmaları sırasında tespit edilen veriler, bölge merkezleri ile karşılaştırılarak detaylı olarak incelenmiş ve Geç Demir Çağı tabakasında gün ışığına çıkarılan mimari geleneklerin değişimi kronolojik olarak sunulmuştur.

Published: October 2023

Криптографічний захист інформації є важливою складовою інформаційної безпеки. Розробка нових методів криптоаналізу допомагає зрозуміти межі стійкості наявних криптосистем. Сучасний криптоаналіз опирається на різні математичні дисципліни, зокрема, на теорію та методи оптимізації. Враховучи загальновизнані вимоги до стійкості шифрів, задача розшифрування може розглядатися як задача комбінаторної оптимізації. Методи та алгоритми комбінаторної оптимізації сьогодні відіграють важливу роль у дослідженнях, пов’язаних з колом проблем, що безпосередньо впливають на інформаційну безпеку. Задача криптографічного захисту інформації вирішується створенням нових та вдосконаленням існуючих алгоритмів шифрування. З іншого боку, стрімко зростаючі можливості обчислювальної техніки відкривають практичні передумови впровадження технологій криптоаналізу, недоступних раніше. Зокрема, до актуальних технологій криптоаналізу можна віднести застосування оптимізаційних рандомізованих алгоритмів для інтелектуального дослідження простору пошуку з метою отримання прийнятного результату. Теоретично обгрунтовано, що такі алгоритми, за певних умов, дозволяють отримати розв’язок, коли ймовірність успіху дуже мала. Основним інструментом аналізу ефективності оптимізаційних рандомізованих алгоритмів є обчислювальний експеримент. Аналіз можливості, особливостей та меж застосування метаевристичних алгоритмів криптоаналітиками вказує на перспективу використання метаевристичного підходу як універсального методу криптоаналізу. В роботі обгрунтовується необхідність розвитку нових методів криптоаналізу із застосуванням метаевристик, міститься ретрспективний огляд публікацій за останній період в даній області. Число публікацій свідчить про актуальність напрямку досліджень.

Published: October 2023

У роботі дифузійні хромосиліцидні покриття наносили на сталь 45 газовим методом у спеціально розробленій установці, яка мала спеціальну реакційну камеру нової конструкції. Процес проводили впродовж 6 годин у замкнутому реакційному середовищі при тиску активної газової фази та температурі 1323К. В якості вихідних реагентів для нанесення дифузійних покриттів використовували порошки феросиліцію, хрому, а також чотирихлористий вуглець. Металографічні дослідження проводили на оптичному мікроскопі «Neophot 21». Встановлено, що комплексні покриття за участю хрому та кремнію, нанесені на поверхню сталі 45, згідно з даними мікроструктурного аналізу, складаються з зовнішнього шару до 20∙10-6 м, який містить карбіди хрому Cr23C6, Cr7C3 та внутрішнього шару до 80∙10-6 м, який представляє собою твердий розчин кремнію та хрому у α-залізі. Корозійну стійкість хромосиліцидних дифузійних покриттів досліджували у 10–15% розчинах соляної, фосфорної, оцтової, нітратної кислотах, у 3% розчині хлориду натрію та у технічній воді. Показано, що дифузійні хромосиліцидні покриття, нанесені на вуглецеві сталі підвищують корозійну стійкість у досліджених розчинах у 2,5–750 раз. Підвищити корозійну стійкість дифузійних покриттів можливо за рахунок введення неорганічних речовин (молібдату натрію). Введення у 10% розчини фосфорної, соляної та сульфатної кислоти 3г/л молібдату натрію підвищує корозійну стійкість хромосиліцидних покриттів у 4, 7 та 36 разів, відповідно. Показано, що хромосиліцидні покриття можна рекомендувати для захисту деталей машин, які працюють у різних агресивних середовищах.
