Ultrafast-laser-inscribed multiscan type-I mid-infrared waveguides and beamsplitters in IG2
Authors: Gebremichael Wendwesen , Oliwa Derek , Fernandes John , Dorrer Christophe , Qiao Jie
Published: February 2024

This study reports the fabrication and characterization of various configurations of mid-infrared waveguides and beamsplitters within the chalcogenide glass IG2 using ultrafast laser inscription (ULI). Our investigation reveals two distinct regimes of ULI modification: weak and strong. The strong regime, marked by higher pulse energies, presents darker and prominent waveguide morphology, enabling efficient light guiding at 4.55 µm, but with higher scattering losses at shorter wavelengths. In the weak regime, we observed a significant enhancement in the mode confinement and a reduction in the propagation loss within the multilayer structures. We have investigated key geometric and inscription parameters such as inscription pulse energy and number of layers, as well as arm separation and splitting angles for beamsplitters. We have successfully fabricated beamsplitters with configurations ranging from 1 × 2 to 1 × 8, achieving a uniform splitting ratio over 96% and a splitting loss as low as 0.4 dB at 4.55 µm. These findings highlight the significant potential of ULI-based IG2 waveguides and beamsplitters for mid-infrared photonics.
3D object tracking using integral imaging with mutual information and Bayesian optimization
Authors: Wani Pranav , Usmani Kashif , Krishnan Gokul , Javidi Bahram
Published: February 2024

Integral imaging has proven useful for three-dimensional (3D) object visualization in adverse environmental conditions such as partial occlusion and low light. This paper considers the problem of 3D object tracking. Two-dimensional (2D) object tracking within a scene is an active research area. Several recent algorithms use object detection methods to obtain 2D bounding boxes around objects of interest in each frame. Then, one bounding box can be selected out of many for each object of interest using motion prediction algorithms. Many of these algorithms rely on images obtained using traditional 2D imaging systems. A growing literature demonstrates the advantage of using 3D integral imaging instead of traditional 2D imaging for object detection and visualization in adverse environmental conditions. Integral imaging’s depth sectioning ability has also proven beneficial for object detection and visualization. Integral imaging captures an object’s depth in addition to its 2D spatial position in each frame. A recent study uses integral imaging for the 3D reconstruction of the scene for object classification and utilizes the mutual information between the object’s bounding box in this 3D reconstructed scene and the 2D central perspective to achieve passive depth estimation. We build over this method by using Bayesian optimization to track the object’s depth in as few 3D reconstructions as possible. We study the performance of our approach on laboratory scenes with occluded objects moving in 3D and show that the proposed approach outperforms 2D object tracking. In our experimental setup, mutual information-based depth estimation with Bayesian optimization achieves depth tracking with as few as two 3D reconstructions per frame which corresponds to the theoretical minimum number of 3D reconstructions required for depth estimation. To the best of our knowledge, this is the first report on 3D object tracking using the proposed approach.
Unstructured satellite survey detects up to 20% of archaeological sites in coastal valleys of southern Peru
Authors: Snyder Thomas J. , Haas Randall
Published: February 2024

Satellite survey is widely used for archaeological site discovery, but the efficacy of the method has received little systematic investigation. In this analysis, twelve study participants of different experience levels performed an unstructured remote survey of 197 km2 in the Sama and Moquegua valleys of south central Peru where previous pedestrian surveys recorded 546 archaeological sites. Results indicate an average site discovery rate of 9.3% (0–18%, 95% range). The most experienced participants detect up to 20% (17–22%) of known archaeological sites. These detection rates can be used to derive reliable site frequency estimates on the Andean coast, which can be used in planning and budgeting for field efforts and estimating demographic patterns at large spatial scales that are difficult to achieve through pedestrian survey. More generally, this analysis offers a method for deriving correction terms specific to other parts of the world. Additionally, the results can serve as a baseline for evaluating the effectiveness of emerging artificial intelligence routines for archaeological site detection.
Bilingual translations of intensifiers in Dong-A Ilbo’s news about China: A corpus-based discourse analysis approach
Authors: Jiuding Quan
Published: February 2024

Drawing on the framework of Ideological Square Model, this paper carries out a corpus-based analysis of the ways in which group relations and the image of China are re-shaped in the English translation (ET) and the Chinese translation (CT) of Korean news discourse about China with intensifiers as an entry of inquiry. The results show that (1) There is a statistically significant difference regarding faithfulness between the ET and the CT of intensifiers (χ2 = 38.11>3.84, p<0.05), with the ET having more translation shifts. Additionally, the Chi-square test of a 3x3 contingency table (T = 49.77>5.99, P<0.05) indicates that there is a difference between the distribution of translation shifts at the 3 levels between ET and CT. (2) The ET of Korean news about China aligns more closely with van Dijk’s ideological square model, while CT violates. It is argued that South Korean media have ideological factors to consider when it comes to Chinese readers accepting CT. (3) There is an alteration of the ideological square model in the target texts. The results indicate that in the translation of a target language, the translation propensity for relevant topics of the target country in which the language is spoken obeys the rules of “Us”, the ingroup, but not “them”, the outgroup.

Authors: Ali Md. Liakot , Sadi Muhammad Sheikh , Goni Md. Osman
Published: February 2024

Cardiovascular diseases (CVD) also known as heart disease are now the leading cause of death in the world. This paper presents research for the design and creation of a fuzzy logic-based expert system for the prognosis and diagnosis of heart disease that is precise, economical, and effective. This system entails a fuzzification module, knowledge base, inference engine, and defuzzification module where seven attributes such as chest pain type, HbA1c (Haemoglobin A1c), HDL (high-density lipoprotein), LDL (low-density lipoprotein), heart rate, age, and blood pressure are considered as input to the system. With the aid of the available literature and extensive consultation with medical experts in this field, an enriched knowledge database has been created with a sufficient number of IF-THEN rules for the diagnosis of heart disease. The inference engine then activates the appropriate IF-THEN rule from the knowledge base and determines the output value using the appropriate defuzzification technique after the fuzzification module fuzzifies each input depending on the appropriate membership function. Moreover, the fusion of web-based technology makes it suitable and cost-effective for the prognosis of heart disease for a patient and then he can take his decision for addressing the problem based on the status of his heart. On the other hand, it can also assist a medical practitioner to reach a more accurate conclusion regarding the treatment of heart disease for a patient. The Mamdani inference method has been used to evaluate the results. The system is tested with the Cleveland dataset and cross-checked with the in-field dataset. Compared with the other existing expert systems, the proposed method performs 98.08% accurately and can make accurate decisions for diagnosing heart diseases.

Authors: Wang Weiwei , Zhao Xinjie , Jia Yanshu , Xu Jiali
Published: February 2024

The objectives are to improve the diagnostic efficiency and accuracy of epidemic pulmonary infectious diseases and to study the application of artificial intelligence (AI) in pulmonary infectious disease diagnosis and public health management. The computer tomography (CT) images of 200 patients with pulmonary infectious disease are collected and input into the AI-assisted diagnosis software based on the deep learning (DL) model, "UAI, pulmonary infectious disease intelligent auxiliary analysis system", for lesion detection. By analyzing the principles of convolutional neural networks (CNN) in deep learning (DL), the study selects the AlexNet model for the recognition and classification of pulmonary infection CT images. The software automatically detects the pneumonia lesions, marks them in batches, and calculates the lesion volume. The result shows that the CT manifestations of the patients are mainly involved in multiple lobes and density, the most common shadow is the ground-glass opacity. The detection rate of the manual method is 95.30%, the misdetection rate is 0.20% and missed diagnosis rate is 4.50%; the detection rate of the DL-based AI-assisted lesion method is 99.76%, the misdetection rate is 0.08%, and the missed diagnosis rate is 0.08%. Therefore, the proposed model can effectively identify pulmonary infectious disease lesions and provide relevant data information to objectively diagnose pulmonary infectious disease and manage public health.
The reliability of a linear position transducer for measuring countermovement jump performance in national-level road cyclists
Authors: Turner Aaron , McKean Mark , Doyle Danielle , Burkett Brendan
Published: February 2024

Background

Jump tests have applications in fatigue monitoring, training intervention evaluations, and talent identification in cycling populations. Due to competitive cycling’s inherent travel demands, linear position transducers (LPTs) are suitable for assessing jump performance in this population as they are a mobile and validated technology. Understanding the reliability and sensitivity of LPTs in assessing jump performance in cycling populations is required to support the development of sports science protocols. Using an LPT, this study aimed to determine the reliability and sensitivity of countermovement jump (CMJ) variables in road cyclists.

Methods

Ten national-level male road cyclists performed three maximal CMJ trials twice per week for two weeks, with an LPT measuring force, power, velocity, repetition rate, vertical distance, and concentric time from each trial. Using the mean and best CMJ results from three trials per testing session, the upper limit 90% confidence interval for the coefficient of variation (CV) and smallest worthwhile change (SWC) determined inter-day and -week reliability (CV ≤ 10%) and sensitivity (acceptable sensitivity = CV ≤ SWC) for CMJ variables.

Results

Mean power and force, velocity (mean and peak), vertical distance (VD), and concentric time had acceptable inter-day and -week reliability when using either the mean or best CMJ results (CV upper limit 90% confidence interval range = 3.54–10.13%). Moreover, the CV and SWC were typically lower when based on the mean rather than the best of three CMJ trials. Lastly, poor sensitivity (CV > SWC) was evident for all CMJ variables.

Conclusions

CMJ-derived mean power and force, velocity (peak and mean), VD, and concentric time have acceptable inter-day and -week reliability when assessed via an LPT in national-level road cyclists. When using an LPT, sports scientists should consider that, while they typically have poor sensitivity, the reliability of CMJ-derived variables improves when expressed as the mean of three trials in national-level road cyclists.

Authors: Marco-Lajara Bartolomé , Zaragoza-Sáez Patrocinio , Martínez-Falcó Javier , Gilinsky Armand
Published: February 2024

Wine tourism is increasingly considered as a strategic element in the wine producing countries of the Old World. In the case of Spain, several researchers have studied the role of wine routes in boosting the competitiveness of a territory, increasing wine production, improving the quality of life of citizens and the respect for the environment. However, to the best of our knowledge, there are no previous studies that have analyzed in a unified way the wine routes of the Region of Valencia, that is, the wine routes of Alicante and Utiel-Requena. To overcome this research gap, the study comparably analyzes these wine routes in terms of attracting wine tourists and the economic impact generated in the period 2017-2021, also relativizing the data to the average of the total Spanish wine routes. The results of the research show that both routes attract a lower number of wine tourists than the average of the Spanish wine routes. In addition, it should be noted that the Utiel-Requena route generated a higher economic impact compared to the Alicante wine route between 2017-2019, with this trend reversing in 2019. This study, therefore, contributes to the improvement of scientific knowledge in several ways, given that, first, the research provides new knowledge in the field of wine tourism in Spain and, second, there are no previous studies that have analyzed in a unified way the wine routes in the Region of Valencia.

Published: February 2024

La gestión de los museos, desde inicios del siglo XXI, ha mostrado una creciente implementación de las nuevas tecnologías (códigos QR, Apps, realidad aumentada, realidad virtual, gamificación, entre otros), en aras de proporcionar una mayor satisfacción a sus visitantes. De hecho, la pandemia de la COVID-19 ha acelerado dicho uso, que ya venía gestándose desde inicios de este siglo. Hoy, las tecnologías son recursos clave para la gestión de museos. El objetivo de este artículo es analizar el uso de nuevas tecnologías en museos, a partir de una revisión de la literatura entre el período 2000-2019, etapa previa a la COVID-19. Se ha elegido el período pre-pandemia, puesto que la COVID-19 marca un punto de inflexión, el cierre de un ciclo y el inicio de una nueva etapa. Para este análisis, se recopilaron 130 artículos publicados en revistas del Journal Citation Reports (JCR). La investigación arrojó tres hallazgos principales: el primero indicó que los sistemas multimedia han sido las herramientas tecnológicas más frecuentes dentro de los museos, las cuales en su mayoría están destinadas a la satisfacción de los visitantes. El segundo hallazgo indicó que los artículos académicos con mayor colaboración entre autores, son los más citados en el área académica, independientemente al factor de impacto de la revista. Finalmente, el último hallazgo determinó que la colaboración entre investigadores sigue siendo escasa, especialmente entre investigadores de distintas disciplinas. Este documento contribuye con una evaluación precisa del desarrollo de nuevas tecnologías en el campo de los museos, en la era pre-pandemia.
Narrativas turísticas: en torno al legado colonial afrodescendiente en la ciudad de Buenos Aires
Authors: Cortés Ricardo , Hruby Roxana
Published: February 2024

Las huellas culturales africanas se registran en la ciudad de Buenos Aires desde la etapa colonial. Sin embargo, al momento de reconocer su incidencia en el desarrollo de la ciudad, las nociones de invisibilidad y desaparición prevalecen por sobre las ideas de permanencia y continuidad. En las narrativas turísticas porteñas, los relatos del crisol de raza y de la ciudad europea, se encuentran fuertemente instalados. Desde el supuesto de que “en la Argentina no hay negros” se construyó una imagen de sociedad homogénea blanca y europea, que no se condice con la diversidad cultural que caracterizó la matriz multiétnica y pluricultural del país. Este trabajo se propone analizar algunas de las narrativas turísticas vigentes, contrastando las mismas con los datos obtenidos en documentos, base de datos, literatura actualizada y entrevistas. A tal fin, se problematiza la noción de tradiciones inventadas, que como recurso supletorio suele ser utilizado en los relatos turísticos respecto del patrimonio afrodescendiente.
“Hello tourist, we love you aunque orinéis in the corners”. La turismofobia en la prensa española 2017-2022
Authors: Santana-Jiménez Elena , Díaz-Rodríguez Pablo , Rodríguez-Darias Alberto Jonay
Published: February 2024

La actividad turística entendida como motor de desarrollo económico e impulsada por las políticas públicas, crea impactos y tensiones sociales hasta ahora estudiados por la literatura académica. Conceptos como gentrificación, turistificación o turismofobia, han sido objeto de debate en la última década. Este último, a diferencia de otros, ha adquirido una alta repercusión mediática y política, creando lo que algunos expertos señalan como una “cortina de humo” para evitar confrontar los problemas de gestión turísticos. Este trabajo investiga este fenómeno a partir del análisis del discurso difundido por la prensa española. Con este objetivo, se analiza una selección de noticias de 4 periódicos nacionales (El País, El Mundo, La Razón y elDiario.es) que tuviesen relación con el objeto de estudio. El objetivo que se plantea es comparar las posturas ideológicas sobre la turismofobia en la prensa entre 2017 y 2022, resaltando qué elementos destacan para generar la opinión pública deseada.
Da reedição de designing social inquiry à edição dos novos debates metodológicos
Authors: Lenine Enzo
Published: February 2024

O artigo revisita as discussões metodológicas propostas na obra de KKV por ocasião da publicação de uma nova edição de Designing Social Inquiry. Utilizo como ponto de partida a obra de KKV para analisar as discussões contemporâneas sobre causalidade, explicação e ciência. Parte-se da premissa de que a lógica inferencial de KKV projeta-se como um modelo único de produção de conhecimento, o que contrasta com a pluralidade de concepções dentro da Ciência Política e das Relações Internacionais. Recorrendo aos aportes da filosofia das ciências sociais para avaliar a obra e os debates contemporâneos em ambas disciplinas, aponto três problemáticas na obra de KKV: o problema da causalidade, o problema da explicação e o problema da unificação metodológica. A análise desses problemas evidencia a lógica de ciência que KKV projetam sobre as disciplinas de Ciência Política e RI, sintetizada em uma visão de causalidade oriunda do modelo de Rubin-Holland, centrada na explicação causal como única forma de explicação legítima, e proposta como modelo universal de produção de conhecimento.
New Psychiatry
Authors: Ghaemi Seyyed Nassir , Vohringer Paul
Published: February 2024

This new journal is a challenge to conventional wisdom. Contemporary psychiatry provides average clinical care in the best of circumstances, and poor care in many cases. It lives on failed theories of a past century, and pretends it is avant-garde. The profession’s system of diagnosis, the Diagnostic and Statistical Manual, 5th edition (DSM-5), published by the American Psychiatric Association (APA), is mostly false, and demonstrably so. Yet it is accepted and practiced worldwide as if it was proven true.The profession’s medication treatment approach is based on DSM-5 definitions, and thus is also false and weak in its effects. Yet it is accepted by government regulators and pharmaceutical companies worldwide. Most psychiatric drugs only improve symptoms short-term, at best, like aspirin for a headache or ibuprofen for a fever, yet they are given and assumed to be effective long-term, though few are proven so (such as lithium) and many are disproven long-term. Its psychotherapies are eclectic, and applied more often based on the preferences of practitioners than the needs of patients.
Why does Waqf Literacy Matter?
Authors: Akbar Nashr , Kassim Salina
Published: February 2024

Many studies have highlighted a low literacy level of waqf among Muslims all over the world. In Indonesia, an effort to measure the level of waqf literacy using an index was initiated by the Indonesian Waqf Board in 2020. The result has proven that there is a low level of waqf literacy in Indonesia. This study aims to explore the reasons behind the low level of waqf literacy and understand the importance of waqf literacy. Based on a literature survey, the following aspects need to be clearly explained and elaborated to effectively improve waqf literacy among the public. First, the unique characteristics of waqf compared to other Islamic alms; second, waqf literacy is positively related to waqf collection; third, the utilization of waqf can be further enhanced when the literacy is higher; and fourth, disputes and conflicts about waqf ownership are frequently due to lack of waqf literacy. In summary, this study is expected to increase the interest and attention of all stakeholders toward enhancing waqf literacy. Waqf authorities and waqf institutions are encouraged to intensify education and socialization about waqf, while researchers are expected to study more on waqf literacy. To further develop the waqf sector, it is necessary to have a road map to increase waqf literacy.
Originality/Value: The study aims to explore the reasons behind the importance of waqf literacy in Indonesia. Identifying these reasons in the Indonesian context could pave the way for tailored interventions and policies to improve waqf literacy, which may have implications for similar contexts elsewhere.

The different structural conditions of the seagrass ecosystem in the waters of Bintan Island are thought to influence the association of bivalves in the seagrass ecosystem. This study aims to describe the structure of seagrass ecosystems and study the structure of bivalve associations in several seagrass ecosystems on the coast of Bintan Island. There are four observation stations observed in this study. The determination of the research location was based on the representation of the distribution of seagrass ecosystems on Bintan Island, with different seagrass cover conditions, including: Dompak, Pengudang, Bakau Bay and Pengujan. The sampling method uses a quadratic transect combined with 3 line transects along 100 m seaward, obtaining 7 types of seagrasses scattered in 4 research locations. The highest seagrass cover was found in Pengudang Coastal Area, with a cover value of 66.1%. Found 28 species of bivalves with the highest density value, namely Gafrium pectinatum. PCA analysis results show that seagrass cover has an attachment to the density of bivalves. Some bivalves tend to live on specific seagrass vegetation.

The Isognomon (Lightfoot, 1786) is a genus of oysters found in various coastal ecosystems throughout the world. Along with other bivalves, it performs significant ecological functions in marine ecosystems by providing food and habitat for fish and invertebrate habitats, filtering water, and protecting shorelines. Taxonomic classification of the Isognomon oyster can be challenging due to the varied or cryptic phenotypic characters, particularly shell characters.  In this study, two specimens with different shell characters of Isognomon oyster were collected from mangrove waters in Likupang, North Sulawesi, Indonesia, and subjected to molecular analysis to determine their identity.  The mitochondrial cytochrome C oxidase subunit I (COI) gene was utilized as a primer for this purpose, and the genetic distance and phylogenetic position of the two specimens were determined by comparing them with the GenBank database. The Basic Local Alignment Search Tool (BLAST) revealed that the two specimens were of belonged to Isognomon ephippium, with a similarity of 99.84%. The genetic distance between the two specimens was calculated using the Tamura Nei model and found to be 0.00, while the genetic distance between I. ephippium and other species in the Isognomon genus ranged from 0.00 to 0.14. The results of the Neighbor Joining (NJ) tree analyses showed that the two specimens clustered together with I. ephippium, which was divided into two distinct clades with a strong bootstrap value of 100 at the node

Published: February 2024

Shellfish are also known as by-products, namely production results that are not utilized or not consumed, where the value of this by-product can be increased/added through a process known as Reduce-Reuse and Recycle (3R). This research aims to determine the potential of shellfish as a source of calcium. Samples of clams (Paphia undulata), blood clams (Tegillarca granosa), and Asian Moon Scallop (Amusium pleuronectes) were obtained from Tambak Lorok Fish Auction Place, Semarang; then taken to the Marine Biology Laboratory, Faculty of Fisheries and Marine Sciences, Universitas Diponegoro to have the shells, and air dry until dry after drying the shell. Calcium and mineral content were analyzed using the XRF method at the Integrated Laboratory, Universitas Diponegoro. The results of the study showed that the calcium (CaO) content of the three shellfish was the lowest in the clam (P. undulata) at 45.79%, then the Asian moon Scallop (A. pleuronectes) at 45.89%, and the highest in the blood cockle T. granosa namely 92.41%.  It can be concluded that the shells of clams, blood clams, and Asian Moon Scallops contain high levels of calcium and minerals, which have the potential to be used as an additional ingredient in concrete/paving blocks and fish feed.

Published: February 2024

Artykuł zadaje pytanie o autobiografizm neoawangardowej twórczości literackiej Witolda Wirpszy, próbując określić znaczenie, jakie zajmuje w niej gatunek dziennika. Wychodząc od analizy jego wypowiedzi metaliterackich, autor kreśli portret Wirpszy jako twórcy odrzucającego biografizm na rzecz eksperymentu, pokazując jednocześnie, że część jego wierszy (zwłaszcza z tomów Granica wytrzymałości i Przypomnienie Hioba) oraz powieści (Pomarańcze na drutach, Sama niewinność) czytać można jako efekt podjęcia eksperymentalnej gry z gatunkami life writing. Z kolei analiza niepublikowanych dzienników Wirpszy zachowanych w jego archiwum, zwłaszcza zeszytu zatytułowanego Zapiski datowane, bez porządku, potwierdza niechęć poety do intymistyki i utrwalania stanów psychicznych.
Wielka nuda kontemplacji. Eksperymentalne zapisy chorobowe Franciszki Themerson
Authors: Sroka Honorata
Published: February 2024

W artykule omówione zostało pojęcie eksperymentalnych i chorobowych zapisów życia na podstawie korespondencji Franciszki Themerson, a także jej rysunków korespondencyjnych oraz dzieł sztuki. Zauważyłam, że awangardystka stosowała spójne metody kompozycyjne w podejmowaniu tematu swojej choroby tak w zapisach życia, jak i w sztuce awangardowej. Taktyka „przekształcenia” przybierała w przypadku korespondencji, rysunków oraz obrazów formy autoironii, żartu, dystansowania się wobec własnej cielesności w stanie chorobowym. Przeanalizowana korespondencja jest jednym z nielicznych przykładów znanych nam zapisów autobiograficznych malarki, które w większości zdeponowane zostały w Muzeum Sztuki w Łodzi, częściowo również w Bibliotece Narodowej w Warszawie (Archiwum Themersonów).

First record of blister pearls in the oyster Hyotissa hyotis (Linné, 1758) from Pliocene deposits at Sidi Brahim, Lower Chelif Basin (north-west Algeria)
Authors: Khalili Rachid , Vinn Olev
Published: February 2024

Fossil pearls are rare but important palaeoecological indicators in proving the former presence of parasites. A single right valve of Hyotissa hyotis from the Pliocene of Sidi Brahim shows numerous blister pearls inside the adductor muscle imprint. At the same locality, numerous shells with smooth adductor scars and without any blisters, have been collected. The structures in the studied valve can be assigned to blister pearls with high confidence due to their similarity to other Cenozoic pearls from Austria. The blister pearls likely formed as a reaction to parasite infestation. It is possible that some parasites especially targeted areas associated with the adductor muscles in the oyster genus Hyotissa, because similar blister pearls have previously been described in a congeneric species, H. squarrosa, from the Miocene of Austria.

An Attempt to Interpret a Special Testamentary Provision in the Early Modern Transylvanian Wills Although testaments have long been in the focus of academic interest, there are still questions that are yet to be answered. One example is the disposition in a will where the testator has left certain assets to a person in a redeemable form. ln the present study l will attempt to interpret this particular type of provision on the basis of archival sources.

"Some are reverential, but inexperienced in archaeology however they want to honour the Holy Familyin this carving" Popular Interpretation of Two Roman Tombstones in Flóris Rómer's Travel NotesIn my study, I examine two Roman tomb steles based on the manuscript notebooks of archaeologistFlóris Rómer (1815-1889). From Rómer's note No. VII it turns out that the Lupa 3843 tombstone stoodin Ószőny in 1859, and in its carving the locals honoured the Holy Family (Fig. 1). According tothe archaeologist's notebook No. VIII (1860), the inhabitants of the settlement also recognized theHoly Family in a Roman tombstone on the border of Tarján (Fig. 2). The unpublished stone monumentstill stands in the same place today and is called St.Anne's picture in the vernacular.

What is Natural and What is Artificial – In the Light of Social Evolution and the Parallel of Folk Law and Created Law Folk law has an objectified existence; it does not have a formal, codified formality. Nor does it have a definitive character. It is not separate from people's life and therefore has no existence capable of opposing it. Yet it is itself law, which demands fulfilment within its own sphere. It is not formalised and therefore has no system, doctrine or dogmatics. It has no principles or techniques either.

When students think of evolution, they might imagine T. rex, or perhaps an abiotic scene of sizzling electrical storms and harsh reducing atmospheres, an Earth that looks like a lunar landscape. Natural selection automatically elicits responses that include “survival of the fittest,” and “descent with modification,” and with these historical biological catch phrases, one conjures up images of large animals battling it out on the Mesozoic plane. Rarely do teachers or students apply these same ideas to cancer and the evolution of somatic cells, which have accrued mutations and epigenetic imprinting and relentlessly survive and proliferate. Our questions in this paper include the following: Can cancer become an important teaching model for students to explore fundamental hypotheses about evolutionary process? Can the multi- step somatic cancer model encourage visualizations that enable students to revisit and reenter previous primary concepts in general biology such as the cell, mitosis, chromosomes, genetic diversity, ecological diversity, immune function, and of course evolution, continually integrating their biology knowledge into process and pattern knowledge? Can the somatic cancer model expose similar patterns and protagonists, linking Darwinian observations of the natural world to our body? And, can the cancer clone model excite critical thinking and student hypotheses about what cancer is as a biological process? Does this visually simple model assist students in recognizing patterns, connecting their biological curriculum dots into a more coherent learning experience? These biological dynamics and intercepting aptitudes of cells are amplified through the cancer model and can help shape the way biology students begin to appreciate the interrelatedness of all biological systems while they continue to explore pivotal points of biological fuzziness, such as the microbiome, limitations of models, and the complex coordination of genomic networks required for the function of even a single cell and the realization of phenotypes.

In this paper we use clonal evolution of cancer as a model experience for students to recreate how a single, non-germline cell appears to shadow the classic pattern of natural selection in body cells that have gone awry. With authentic STEAM activities students can easily crossover and revisit previous biological topics and the ubiquitous nature of natural selection as seen in the example of somatic cells that result in a metastasizing tumor, giving students insight into natural selection’s accommodating and tractable patterns throughout the planet.

Анотація. Досліджені процеси структуроутворення в аустенітній сталі. На прикладі закономірностей фазових перетворень обґрунтована можливість значного скорочення матеріальних витрат на отримання експериментальних залежностей механічних властивостей від режимів термічної обробки. Побудовані адекватні математичні моделі фізичних процесів при старінні сталі. Для побудови моделей використані три різних метода: метод обробки експериментальних результатів кубічним сплайном VDSP3; метод обробки  з використанням математичного пакету функціонального програмування WolframMathematica; і метод симплекс планів Шеффе. Порівняльний аналіз зазначених способів математичної обробки показав придатність і можливість їх використання для візуалізації процесів старіння сталей. Обчислені коефіцієнти поліномів другого, неповного четвертого та четвертого ступеня і критерії Стьюдента. Визначені довірчі інтервали розрахунків значень механічних властивостей сталі. Встановлена і проаналізована стадійність фазових перетворень при ізотермічній витримці. Старіння відбувається у три стадії: на першій розвиваються процеси зміцнення, за рахунок формування сегрегацій передвиділення зміцнюючої фази; на другій стаді відбувається максимальне зміцнення, формуються частки зміцнюючої фази, які когерентно пов’язані з аустенітною матрицею; на третій стадії, за рахунок активізації дифузійних процесів і перерозподілу легуючих елементів відбувається перестарення, яке призводить до зниження міцності сталі і підвищення ударної в’язкості.  Визначені температурно-часові інтервали кожної стадії старіння. Побудовані геометричні моделі у вигляді контурних карт ізоліній твердості і ударної в’язкості, за якими досить просто назначати режими термічної оброки для досягнення потрібного комплексу механічних властивостей. Розроблені практичні рекомендації  щодо отримання потрібного комплексу механічних властивостей аустенітної сталі.

Анотація.  Ракето-носії (РН) є основними засобами виведення космічних апаратів (КА) на орбіти і доставки бойових частин на територію супротивника. Незважаючи на те, що існує багато методів і моделей виведення космічних апаратів (КА) на навколоземні орбіти, досі актуальними залишаються питання ефективності програми запуску з погляду таких критеріїв як максимізація корисного навантаження, мінімізація витрат пального, можливість кластерного виведення супутників, точність попадання бойових частин на територію супротивника та ін.Практичний досвід показує, що під час виведення КА на орбіту точність виведення по висоті становить 20-30 км, а точність забезпечення кінцевої швидкості на активній ділянці сягає 100-200 м/с, що впливає на відхилення орбіт КА від планових. Одночасне поліпшення точності виведення КА на орбіту за координатами і за швидкістю досі є важливим завданням.Розглядаються математичні моделі і методи виводу КА на кругові орбіти Землі, а також критерії і методи оптимізацію руху РН на активній ділянці. Проведено аналітичний огляд методів і моделей, які використовуються для дослідження руху РН на активній дільниці траєкторії руху, а також критерії, які використовуються для оптимізації руху.  Здійснено класифікацію цих методів та моделей, яка може бути використана для створення більш ефективних програм руху РН на активній ділянці траєкторії польоту. Створена класифікація дозволяє більш системно і зважено підійти до вибору та реалізації моделі руху РН, на основі якої далі буде проводитися оптимізація програми тангажу. Розглянутий підхідвирішення задачі виводу РН на задану висоту з заданим напрямком та величиною швидкості. Наводиться обрана математична модель опису руху РН на активній дільниці для проведення досліджень, а також програмні продукти, які плануються використати для рішення задачі.

Анотація. Об’єктом дослідження є конструкція відсіку шасі носової стійки пасажирського літака Boeing 737.Метою роботи є дослідження напружено-деформованого стану локальної зони конструкції відсіку.Для опису напружено-деформованого стану стінки відсіку носової стійки шасі, а також для верифікації місцевої СЕ моделі використано модель циліндричного згину пластин типу Тимошенко. Було побудовано аналітично-математичну модель даної конструкції для задачі циліндричного згину пластини на пружних опорах та отримано аналітичний розв’язок. Отриманоформули для розрахунку прогинів, кутів повороту перерізів пластини, кривизни функції прогину, розподілення моменту по ширині пластини, нормальних напружень на верхній та нижній поверхні пластини. На етапі знаходження подовження пластини прийшли до трансцендентного рівняння з алгебраїчними та гіперболічними функціями, яке неможливо вирішити аналітично. Рішення цього рівняння представили у чисельному вигляді за допомогою програмної середи MS Excel. Далі проведено порівняльний аналіз отриманих результатів побудованої аналітичної моделі з чисельними розрахунками, які використовували програмні комплексиPATRAN/NASTRAN та Excel. Змінюючи параметр піддатливості опор можна отримати не тільки проміжні граничні умови, а й умови які відповідають шарнірним або абсолютно жорстким опорам. Було розглянуто випадок з шарнірними опорами. Для розрахунку було взято пластину зі сплаву алюмінію 7075-T7351 з параметрами E=10.6•106 psi, μ=0.33.Побудовано графіки розподілення згинаючого моменту по ширині пластини, прогину, кутів повороту нормалі та кривини пластини, сумарних нормальних напружень для обох випадків. Отримані розрахунки показали, що чисельний та аналітичний розв’язок з інженерною точністю можна вважати ідентичними. Методики та розрахунки представлені в даній роботі можна взяти за основу в проектуванні нових літаків, та оцінки втомної довговічності деталей.
