Seeing the wood for the trees: active human–environmental interactions in arid northwestern China
Authors: Shen Hui , Spengler Robert N. , Zhou Xinying , Betts Alison , Jia Peter Weiming , Zhao Keliang , Li Xiaoqiang
Published: May 2024

Abstract. Due largely to demographic growth, agricultural populations during the Holocene became increasingly more impactful ecosystem engineers. Multidisciplinary research has revealed a deep history of human–environmental dynamics; however, these pre-modern anthropogenic ecosystem transformations and cultural adaptions are still poorly understood. Here, we synthesis anthracological data to explore the complex array of human–environmental interactions in the regions of the prehistoric Silk Road. Our results suggest that these ancient humans were not passively impacted by environmental change; rather, they culturally adapted to, and in turn altered, arid ecosystems. Underpinned by the establishment of complex agricultural systems on the western Loess Plateau, people may have started to manage chestnut trees, likely through conservation of economically significant species, as early as 4600 BP. Since ca. 3500 BP, with the appearance of high-yielding wheat and barley farming in Xinjiang and the Hexi Corridor, people appear to have been cultivating Prunus and Morus trees. We also argue that people were transporting preferred coniferous woods over long distances to meet the need for fuel and timber. After 2500 BP, people in our study area were making conscious selections between wood types for craft production and were also clearly cultivating a wide range of long-generation perennials, showing a remarkable traditional knowledge tied into the arid environment. At the same time, the data suggest that there was significant deforestation throughout the chronology of occupation, including a rapid decline of slow-growing spruce forests and riparian woodlands across northwestern China. The wood charcoal dataset is publicly available at https://doi.org/10.5281/zenodo.8158277 (Shen et al., 2023).
GEOMAPLEARN 1.0: Detecting geological structures from geological maps with machine learning
Authors: Oakley David , Loiselet Christelle , Coowar Thierry , Labbe Vincent , Callot Jean-Paul
Published: May 2024

Abstract. The increasing availability of large geological datasets together with modern methods of data analysis facilitate a data science approach to geology in which inferences are drawn from geological data using automated methods based on statistics and machine learning. Such methods offer the potential for faster and less subjective interpretations of geological data than are possible from a human interpreter, but translating the understanding of a trained geologist to an algorithm is not straightforward. In this paper, we present automated workflows for detecting geological folds from map data using both unsupervised and supervised machine learning. For the unsupervised case, we use regular expression matching to identify map patterns suggestive of folds along lines crossing the map. We then use the hdbscan clustering algorithm to cluster these possible fold identifications into a smaller number of distinct folds, the number of which is not known a priori. For the supervised learning case, we use synthetic models of folds to train a convolutional neural network to identify folds using map and topographic data. We test both methods on synthetic and real datasets.
Combining neural networks and data assimilation to enhance the spatial impact of Argo floats in the Copernicus Mediterranean biogeochemical model

Published: May 2024

Abstract. Biogeochemical-Argo (BGC-Argo) float profiles provide substantial information on key vertical biogeochemical dynamics and have been successfully integrated in biogeochemical models via data assimilation approaches. Although BGC-Argo assimilation results have been encouraging, data scarcity remains a limitation with respect to their effective use in operational oceanography. To address availability gaps in the BGC-Argo profiles, an observing system experiment (OSE) that combines a neural network (NN) and data assimilation (DA) was performed here. A NN was used to reconstruct nitrate profiles, starting from oxygen profiles and associated Argo variables (pressure, temperature, and salinity), while a variational data assimilation scheme (3DVarBio) was upgraded to integrate BGC-Argo and reconstructed observations in the Copernicus Mediterranean operational forecast system (MedBFM). To ensure the high quality of oxygen data, a post-deployment quality control method was developed with the aim of detecting and eventually correcting potential sensors drift. The Mediterranean OSE features three different set-ups: a control run without assimilation; a multivariate run with assimilation of BGC-Argo chlorophyll, nitrate, and oxygen; and a multivariate run that also assimilates reconstructed observations. The general improvement in the skill performance metrics demonstrated the feasibility of integrating new variables (oxygen and reconstructed nitrate). Major benefits have been observed with respect to reproducing specific biogeochemical-process-based dynamics such as the nitracline dynamics, primary production, and oxygen vertical dynamics. The assimilation of BGC-Argo nitrate corrects a generally positive bias of the model in most of the Mediterranean areas, and the addition of reconstructed profiles makes the corrections even stronger. The impact of enlarged nitrate assimilation propagates to ecosystem processes (e.g. primary production) at a basin-wide scale, demonstrating the importance of the assimilation of BGC-Argo profiles in forecasting the biogeochemical ocean state.

Published: May 2024

Purpose: Chronic Obstructive Pulmonary Disease has a progressive nature that limits daily-life activities. It is essential that the spiritual needs of patients not be neglected and that they be included in the daily clinical routine appropriately. This study was conducted to determine factors influencing spiritual well-being among people with chronic obstructive pulmonary disease.
Material and Methods: In cross-sectional analysis, comparative and relational analyses of spiritual well-being were calculated based on demographic-clinical characteristics, sleep quality, quality of life, anxiety. Data collection tools were Spiritual Well-Being Scale, Pittsburgh Sleep Quality Index, St. George Respiratory Questionnaire and Spielberger State-Trait Anxiety Inventory. Further analysis was carried out with multiple linear regression analysis.
Results: Those who did not take the recommended dose of medication and did not use devices at home were associated with higher spiritual well-being. Sleep quality, quality of life and trait anxiety had an explanatory value of 24% for spiritual well-being. The best predictive variable was found to be trait anxiety.
Conclusion: Identifying factors associated with spiritual well-being may allow the determination of the health requirements for holistic health management in clinical practice. In-depth analyzes of spiritual well-being, to be conducted with a wider range of variables, may reveal potential mechanisms on the health outcomes of people with chronic obstructive pulmonary disease.
CURRENT OVERVIEW OF CLINICAL AND RADIOLOGICAL FINDINGS ASSOCIATED WITH CEREBRAL AMYLOID ANGIOPATHY
Authors: Kızıldağ Betül , Yurttutan Nursel
Published: May 2024

Cerebral amyloid angipopathy (CAA), the second most common cause of spontaneous acute intracerebral hemorrhage after hypertension in the elderly population is characterized by brain parenchymal damage secondary to hemorrhage and ischemia caused by the accumulation of Aβ protein in the walls of small arteries and arterioles. Advanced age is the most significant risk factor for CAA. While the definitive diagnosis requires histopathological examination through autopsy/biopsy, the probable or possible diagnosis of CAA is based on clinical features as well as characteristic neuroimaging findings.
With the increasing elderly population and the growing prevalence of succesibility-weighted magnetic resonance imaging sequences in routine, it becomes imperative to have a thorough understanding of the imaging spectrum associated with CAA. Early diagnosis is extremely critical in patients with CAA who have not yet developed intracranial hemorrhage. Furthermore, patients with CAA may present clinically transient focal neurological episodes or cognitive impairment, which can be mistaken for transient ischemic attacks caused by convexity subarachnoid hemorrhage. Additionally, before initiating newly introduced anti-amyloid monoclonal antibody drugs in Alzheimer's disease, it is necessary to exclude signs of CAA. Moreover, the anticipated side effects of these drugs often manifest imaging abnormalities resembling inflammation or bleeding associated with CAA, necessitating familiarity with the imaging findings of CAA. In this review, the pathophysiology, clinical manifestations, and radiological findings of sporadic CAA will be detailed.

Authors:   , Mendoza Rivera Isela Sarahi
Published: May 2024

Cancer is the second main cause of death in the world, and genetic variation influences a large proportion of its risk. This thesis combined GWAS, 3D chromatin organisation and transcriptomic data to identify candidate hormone-related and skin cancer risk genes. A total of 78 candidate MCR genes were associated with at least two hormone-related cancers, whilst 148 protein-coding and 78 lncRNAs candidate risk genes for skin cancer were identified. The intersection between chromatin features and risk-associated SNPs provide a powerful tool in the identification of new cancer risk genes.

An Empirical Investigation of the Relationship Between Students' Digital Consumption Time and Their Academic Outcome
Authors: Farooq Museera , Ahmad Tusawar Iftikhar , Jahan Musarrat
Published: May 2024

This investigation aims to conduct empirical research on the role that absolute time on social devices has on academic performance as well as evaluate the interaction of social-economic factors in this respect.  An academic study was conducted to measure digital consumption time (the number of hours spent on the internet), academic performance (as reflected by cumulative grade point average), and the different socioeconomic aspects (such as age, number of family members, and monthly income). Analysis of data was done with the use of descriptive statistics, Chi-square tests, and Pearson's correlation analysis. The researcher showed a positive relationship between family income and academic performance. It was found that a statistically significant association between family income and CGPA occurred at a 5% level of significance. Furthermore, a considerable influence of the time spent consuming digital content on academic success was discovered at the 10% level of significance. It implies that moderate use of the internet may result in a higher-earned cumulative grade point average. However, other socioeconomic factors, including age, the size of a household, and the duration of time devoted to varied activities, did not demonstrate any significant correlation to academic performance. According to that study's findings, family income was identified as a major determinant of academic performance; extraneous youth's time spent on consuming digital media was found to be very crucial, though it plays a role of importance on a questionable scale. This supports the implementation of measures encouraging students to be involved only in positive digital activities while having the pupils of less privileged families given help. The academic scores in public sector universities can be ameliorated significantly by planning and implementing intentional programs that focus on leveling the socioeconomic imbalances and improving levels of digital literacy.

Caste system and status co. has become a social evil that portrays the tribulations and tortures of marginalized unprivileged people. A society where social class and caste were pervasive, this study reflects the powerlessness of Bakha who aspired to be an Englishman to get recognition, preserve dignity and to earn an identity as a human. Objective s of present study is to highlight those adjectives indited Mulk Raj Anand in portraying the character sketch of Bakha. The social effect of book is analyzed using Van Djik theory of cognitive approach with a focus on the character of Bakha.This novel depicits the social concern that is analyzed by the van djik theoretical application by close reading of text and purposively sampling of the text relevant to Bakha socially, culturally and economically marginalized. They are common victims and suppressive as they do not have the economic and political power to fight back the upper-class people’s supremacy. They are not able get the voice to speak out their condition and portray themselves before the world. These subalterns have very few chances to change their fate in society which is measured by the upper class and closes the options like consciousness, education and equal rights to raise their status.

Teorijski izazovi tranzicione rekonstrukcije nacionalnog identiteta — slučaj Vojvodine
Authors: Komšić Jovan
Published: May 2024

Polazeći od Hobsbaumove procene dugovečnih perspektiva ksenofobnog nacionalizma u postsocijalističkim režimima centralne i istočne Evrope, kao i od sličnih procena srpskog reditelja i pisca Živojina Pavlovića o mentalitetu, koji “zajednicu… vraća vekovima u praiskonsko stanje apsolutne amorfije”, autor analizira izazove postkomunističkih identitetskih politika u Vojvodini i Srbiji, posredstvom sledećih tematskih segmenata: 1) “Preporodni” zapleti i “kreativnost” oligarhijske uzurpacije građanske suverenosti; 2) Politika identiteta i evropske perspektive vojvođanske multikulturalnosti; 3) Paradoks pluralizma: otvaranje takmičarske scene – zatvaranje u etnonacionalne zajednice; 4) Šanse za liberalnu alternativu oficijelnoj paradigmi “jedne politične narodnosti”. Zaključak je da decentralizacija ipak nije “potrošena” alternativa, odnosno da lokalni i regionalni okvir upravljanja zajednicom nije izgubio sve šanse da, umesto atutoritarno-centralističkog zaluđivanja “sudbinskim identitetom”, poverujemo u vrline i kapacitete građanstva, snagu zdravog razuma i slobodni izbor plana i smisla života.

С целью изучения протекания реакции восстановления хрома в ходе процесса аргонокислородного рафинирования с использованием оксида бора в качестве флюса было проведено термодинамическое моделирование равновесного межфазного распределения хрома между шлаком системы СаО–SiO2–(3–6%)В2О3–12%Cr2O3–3%Al2O3–8%MgO в диапазоне основности 1,0–2,5 и металлом в зависимости от температуры, содержания оксида бора и основности. Результаты моделирования представлены в виде диаграмм зависимости равновесного межфазного распределения хрома от состава шлака для температур 1600 и 1700 °С. Установлено, что повышение основности шлаков c 1,0 до 2,5 при температурах 1600 и 1700 °С приводит в рассматриваемом диапазоне содержания оксида бора к уменьшению коэффициента межфазного распределения хрома с 60,0·10–3 до 1,5·10–3 и, как следствие, повышению степени восстановления хрома с 91 до 99,5%. Рост температуры металла и содержание оксида бора слабо влияют на восстановление хрома. Влияние основности изучаемых шлаков на процесс восстановления хрома можно качественно объяснить с позиции формирования фазового состава и термодинамики реакций восстановления хрома алюминием и кремнием. Экспериментальные исследования подтверждают результаты термодинамического моделирования.

To study the process of chromium reduction during argon–oxygen refining with a use of boron oxide as a flux, thermodynamic modeling of the equilibrium interfacial distribution of chromium between a slag of the oxide system СаО–SiO2–(3–6%)В2О3–12%Cr2O3–3%Al2O3–8%MgO in the range of basicity 1.0–2.5 and metal depending on temperature, boron oxide content, and basicity is made. The modelling results are shown as diagrams of the dependence of the equilibrium interphase distribution of chromium on the composition of the slag for temperatures of 1600 and 1700°C. It is found that an increase in the basicity of slags from 1.0 to 2.5 at temperatures of 1600 and 1700°C leads in the studied range of boron oxide content leads to a decrease in the interfacial distribution coefficient of chromium from 60.0 10–3 to 1.5 10–3 and, as a result, an increase in the degree of reduction of chromium from 91 to 99.5%. An increase in the temperature of the metal and the content of boron oxide have little effect on reduction of chromium. The influence of basicity of the studied slags on the chromium reduction process can be qualitatively explained from the perspective of formed phases in slags and thermodynamics of the reactions of chromium reduction with aluminum and silicon. Experimental studies confirm the results of thermodynamic modeling.

В работе проведено исследование влияния температуры отжига на изменение микроструктуры и свойств колец из нержавеющей стали после деформирования методом кручения под высоким давлением. Анализ микроструктуры образцов после деформирования методом кручения под высоким давлением при комнатной и криогенной температуре показал, что восемь циклов деформирования приводят к получению однородной наноструктуры при обоих значениях температуры, но при использовании криогенного охлаждения получена более мелкозернистая структура. Так, при деформировании с криогенным охлаждением получена мартенситная структура с размером зерна 0,2 μm, а при комнатной температуре получена микроструктура, состоящая из смеси аустенита и α-мартенсита с размером зерна 0,5 μm. Пластические свойства, полученные после такой обработки, недостаточны для дальнейшего использования. Для повышения пластических свойств и проверки возможности обеспечивать сохранение микроструктуры при нагреве образцы после деформирования подвергали отжигу при 300–650 °С и выдержке 15 мин. Ультрамелкозернистая структура, сформированная в стали при деформировании, остается стабильной до температуры 600 °С.

The authers studied the effect of annealing temperature on the change in the microstructure and properties of stainless steel rings after deformation by high-pressure torsion. Analysis of the microstructure of the samples after deformation by high-pressure torsion at room and cryogenic temperatures showed that 8 cycles of deformation leads to a homogeneous nanostructure at both temperatures. But a finer-grained structure was obtained using cryogenic cooling. Thus, when deforming with cryogenic cooling, a martensitic structure with a grain size of 0.2 μm was obtained, while at room temperature a microstructure of 0.5 μm consisting of a mixture of austenite and α-martensite was obtained. The plastic properties obtained after such treatment are insufficient for further use. To increase the plastic properties and to check the possibility of preserving the microstructure when heated the samples after deformation were annealed at temperatures of 300–650 °C and the exposure time of 15 min. The ultrafine grain structure formed in the steel during deformation remains stable up to 600 °C.

Показано, что в покрытиях FeAl/Fe3Al/Fe(Al), сформированных на стальной основе с использованием сварки взрывом и последующей термообработки, основным механизмом разрушения является когезионный. Отслоение и скалывание покрытий происходит только при больших нагрузках. Установлено, что твердость слоистого FeAl/Fe3Al/Fe(Al) покрытия толщиной 440 мкм от подложки к поверхности увеличивается, на расстоянии 200 мкм от поверхности достигает максимума, а затем снижается за счет увеличения пористости. Его относительная износостойкость в ≈1,5 раза выше основы из стали Ст3.

It is shown that in FeAl/Fe3Al/Fe(Al) coatings formed on a steel substrate using explosion welding and subsequent heat treatment, the main failure mechanism is cohesive. Peeling and spalling of coatings occurs only at high loads. It has been established that the hardness of a layered FeAl/Fe3Al/Fe(Al) coating with a thickness of 440 μm increases from the substrate to the surface, reaches a maximum at a distance of 200 μm from the surface, and then decreases due to an increase in porosity. Its relative wear resistance is ~1.5 times higher than the St3 steel substrate.

Пеномагний, благодаря низкой плотности, высоким демпфирующим свойствам, способности поглощать акустические и электромагнитные колебания, биосовместимости с организмом человека является перспективным материалом в промышленности и медицине. Разработанные способы производства изделий из пористого магния фильтрацией жидкого расплава через растворимые гранулы обеспечивают получение пористого магния с размером пор не менее 4 мм. Для уменьшения размера пор путем повышения жидкотекучести и заполняемости гранульной засыпки при получении пористого магния предложена вибрационная обработка расплава в процессе заливки. Проведенные исследования показали, что вибрационная обработка позволяет повысить жидкотекучесть магниевого расплава Мг90. Кроме того, наблюдается измельчение структуры магния и повышение твердости. Вибрационная обработка в процессе заливки и формирования пористого магния способствует увеличению глубины пропитки гранульной засыпки и создает условия для получения изделий из пористого магния с размером пор до 2 мм, плотностью 0,55–0,75 г/см3 и пористостью 57–68%.

Magnesium foam, due to its low density, high damping properties, ability to absorb acoustic and electromagnetic vibrations, biocompatibility with the human body, is a promising material in industry and medicine. The developed methods for the production of products from porous magnesium by filtering a liquid melt through soluble granules ensure the production of porous magnesium with a pore size of at least 4 mm. To reduce the pore size by increasing the fluidity and fillability of the granular filling during the production of porous magnesium, vibration treatment of the melt during pouring is proposed. The conducted studies have shown that vibration treatment makes it possible to increase the fluidity of magnesium melt Mg90. In addition, there is a refinement of the magnesium structure and an increase in hardness. Vibration treatment in the process of pouring and forming porous magnesium contributes to an increase in the depth of impregnation of granular filling and creates conditions for obtaining products from porous magnesium with a pore size of up to 2 mm, a density of 0.55–0.75 g/cm3 and a porosity of 57–68%.

В работе приведено исследование по разработке автоматизированной системы управления барабана моталки. Выявлены причины возникновения проблемных ситуаций не только в условиях конкретного производства, а на основе данных, полученных в результате анализа соответствующей литературы и решения идентичных проблем на других предприятиях. Установлена проблема, заключающаяся в изменении уровня натяжения полосы, вызванная нестабильностью или нарушением работы электропривода моталки. Как следствие, происходит снижение качества прокатываемой полосы, ее разнотолщинность или вовсе обрыв. К тому же установленная система не обладает широким диапазоном уставок, тем самым препятствует расширению сортамента прокатываемой стали. Одной из главных причин, приводящих к названным проблемам, является устаревший двигатель барабана моталки и отсутствие должной системы управления. Представлен полный перечень необходимого оборудования для разработки автоматизированной системы. Приведено математическое описание разработанной автоматизированной системы. Разработан блок компенсации момента для поддержания необходимого уровня натяжения полосы. В программном обеспечении Matlab Simulink синтезирована модель автоматизированной системы управления барабана моталки, в которой проведен анализ натяжения полосы и связанных с ней параметров электропривода (скорости, тока, магнитного потока), подтверждающих отсутствие рывков в ходе намотки. Произведен расчет экономической выгоды внедрения данного проекта. Срок окупаемости – около одного года.

The paper presents a study on the development of an automated control system for the winder drum. The reasons for the emergence of problem situations are identified not only in the conditions of a particular production, but on the basis of data obtained as a result of the analysis of the relevant literature and the solution of identical problems at other enterprises. A problem has been identified in which the strip tension level changes due to instability or malfunction of the winder electric drive. As a result, there is a decrease in the quality of the rolled strip, its thickness variation or even breakage. In addition, the installed system does not have a wide range of settings, thereby preventing the expansion of the range of rolled steel. One of the main reasons leading to these problems is the outdated winder drum motor and the lack of a proper control system. The mathematical description of the developed automated system is given. A moment compensation block has been developed to maintain the required level of strip tension. In the Matlab Simulink software, a model of an automated control system for the winder drum was synthesized, in which the analysis of the strip tension and the associated electric drive parameters (speed, current, magnetic flux) was carried out, confirming the absence of jerks during winding. The calculation of the economic benefits of the implementation of this project was made. The payback period is about a year.

The treatment protocol of mandibular fracture reduction and fixation differs from adults to children because young child has dentition development and mandibular growth process. Many concerns like the cooperation of the patient, displacement of fracture, the skeletal and dental age of the patient are the main factors determine the treatment plan. First option is always the conservative approach. If indicated, we can opt for open reduction and stable fixation as inadequate reduction and fixation will lead to malunion and contour deformities.
