Authors: Ji Li , Zhang Huayong , Wang Zhongyu , Tian Wang , Tian Yonglan , Liu Zhao
Published: September 2024

This research investigated the phytoplankton ecological stoichiometry characteristics and the balance of the relationship between elements in a mountain river in a cold region. The samples of phytoplankton of four seasons were collected in May 2020, August 2020, November 2020, and February 2021 from the Taizicheng River in Chongli, Zhangjiakou City, China. We determined the contents of carbon (C), nitrogen (N), phosphorus (P), sulfur (S), hydrogen (H), and iron (Fe), and analyzed their ecological stoichiometric characteristics and correlation. Our results showed that the contents of C, N, P, S, H, and Fe in phytoplankton were 82.14 ± 32.12 g/kg, 9.22 ± 3.5 g/kg, 1.46 ± 0.55 g/kg, 1.96 ± 0.86 g/kg, 2.36 ± 1.36 g/kg, and 12.64 ± 10.57 g/kg, respectively. Generally, the contents of C, N, and P were relatively stable, while the contents of S, H, and Fe fluctuated greatly, and the coefficient of variation of Fe content was as high as 83.62%. The elemental molar composition of phytoplankton in the Taizicheng River is C156.00N15.41S1.54H51.17Fe5.10P, which showed a significant difference compared with the classical Redfield ratio C106N16P. The high proportion of element C indicated that phytoplankton in the Taizicheng River have a high demand for C and a strong ability to consolidate C. The ratio of N:P was consistent with previous research results. The N:P ratio of phytoplankton in the Taizicheng River was 15.41, suggesting that the growth of phytoplankton in the Taizicheng River was restricted by both N and P. The contents of C, N, and P were positively correlated, while there was no significant correlation among S, H, and Fe. C:P was significantly positively correlated with C:N and N:P, while there were no strong correlations between C:N and C:P, as well as H:S, Fe:S, and H:Fe, indicating that the coupling correlation between phytoplankton elements was different and C, N, and P were highly correlated as important phytoplankton nutrient elements. This study contributes to our understanding of the phytoplankton ecological stoichiometry characteristics and the limiting factors of nutrients in a mountain river and provides a scientific basis for further ecological conservation and management efforts.

Published: September 2024

Perfluoroalkyl carboxylic acids (PFCAs) are a significant group of per- and polyfluoroalkyl substances (PFASs). They are persistent organic chemicals manufactured for their resistance to heat, water, and stains. PFCAs are ubiquitous in the environment, particularly in surface water and wastewater, because they are widely used in everyday consumer products. This contamination poses a risk to drinking water supplies and human health, necessitating sensitive and effective analytical methods. Traditional liquid chromatography–tandem mass spectrometry (LC-MS/MS) is commonly used but involves complex sample handling and high costs. In this study, we developed an enhanced stir bar sorptive extraction (SBSE) method coupled with thermal desorption–gas chromatography–mass spectrometry (TD-GC-MS) for the analysis of PFCAs in water. This method demonstrates linearity, with R2 values from 0.9892 to 0.9988, and low limits of detection (LOD) between 21.17 ng/L and 73.96 ng/L. Recovery rates varied from 47 to 97%, suggesting efficient extraction. Compared to traditional methods, the developed SBSE technique requires only a 1 mL sample volume and minimal amounts of solvents, enhancing eco-friendliness and reducing potential contamination and handling errors. This method also demonstrated good precision and robustness across various water matrices. Overall, the developed method offers a precise, eco-friendly, and reliable approach for analyzing PFCAs in diverse water samples.

Published: September 2024

Water yield (WY) service is the cornerstone of ecosystem functionality. Predicting and assessing the impact of land use/land cover (LULC) changes on WY is imperative for a nation’s food security, regional economic development, and ecological environmental protection. This study aimed to evaluate the water yield (WY) service in Henan Province, China, using high-resolution (30 m) remote sensing land use monitoring data from four study years: 1990, 2000, 2010, and 2020. It also utilized the PLUS model to predict the characteristics of LULC evolution and the future trends of WY service under four different development scenarios (for 2030 and 2050). The study’s results indicated the following: (1) From 1990 to 2020, the Henan Province’s WY first increased and then decreased, ranging from 398.56 × 108 m3 to 482.95 × 108 m3. The southern and southeastern parts of Henan Province were high-value WY areas, while most of its other regions were deemed low-value WY areas. (2) The different land use types were ranked in terms of their WY capacity, from strongest to weakest, as follows: unused land, cultivated land, grassland, construction land, woodland, and water. (3) The four abovementioned scenarios were ranked, from highest to lowest, based on the Henan’s total WY (in 2050) in each of them: high-quality development scenario (HDS), business-as-usual scenario (BAU), cultivated land protection scenario (CPS), and ecological protection scenario (ES). This study contributes to the advancement of ecosystem services research. Its results can provide scientific support for water resource management, sustainable regional development, and comprehensive land-use planning in Henan Province.
Comprehensive Zoning Strategies for Flood Disasters in China
Authors: Li Huipan , Wang Yuan , Ping Liying , Li Na , Zhao Peng
Published: September 2024

The frequency of global floods has increased, posing significant threats to economic development and human safety. Existing flood risk zoning studies in disaster prevention lack integration of the natural–economic–social chain and urban resilience factors. This study addresses this gap by constructing flood disaster risk and intensity indices using data from 31 provinces and 295 prefectural-level cities in China from 2011 to 2022. These indices incorporate natural (rainfall), economic (GDP), and social (population, built-up area) indicators to assess the flood likelihood and loss degree, providing comprehensive risk and intensity ratings. The study also examines the impact of resilience factors—environmental (green space), infrastructural (rainwater pipeline density), and natural resource (watershed areas)—on flood intensity. Findings reveal that high-risk regions are mainly in the Yangtze River Basin and southern regions, while high-intensity regions are primarily in the middle and lower Yangtze River and certain northwestern cities. Increasing rainwater pipeline density mitigates flood impacts in high-risk, high-intensity areas, while expanding green spaces and pipelines are effective in high-risk, low-intensity regions. This paper proposes a comprehensive flood hazard zoning mechanism integrating natural, economic, and social factors with urban resilience, offering insights and a scientific basis for urban flood management.

Published: September 2024

Understanding the interrelationships between land use, climate change, and regional water yield is critical for effective water resource management and ecosystem protection. However, comprehensive insights into how water yield evolves under different land use scenarios and climate change remain elusive. This study employs the Integrated Valuation of Ecosystem Services and Trade-offs (InVEST) models, Patch-generating Land Use Simulation (PLUS) model, and Geodetector within a unified framework to evaluate the dynamics of land use, water yield, and their relationships with various factors (meteorological, social, economic, etc.). To forecast the land use/cover change (LUCC) pattern of the Yellow River Basin by 2030, three scenarios were considered: economic development priority (Scenario 1), ecological development priority (Scenario 2), and cropland development priority (Scenario 3). Climate change scenarios were constructed using CMIP6 data, representing low-stress (SSP119), medium-stress (SSP245), and high-stress (SSP585) conditions. The results show the following: (1) from 2000 to 2020, cropland was predominant in the Yellow River Basin, Henan Province, with significant land conversion to impervious land (construction land) and forest land; (2) water yield changes during this period were primarily influenced by meteorological factors, with land use changes having negligible impact; (3) by 2030, the water yield of Scenario 1 is highest among different land use scenarios, marginally surpassing Scenario 2 by 1.60 × 108 m3; (4) climate scenarios reveal significant disparities, with SSP126 yielding 54.95 × 108 m3 higher water yield than SSP245, driven predominantly by precipitation; (5) Geodetector analysis identifies precipitation as the most influential single factor, with significant interactions among meteorological and socio-economic factors. These findings offer valuable insights for policymakers and researchers in formulating land use and water resource management strategies.
Interrelationship between Wall and Beach Erosion in Loc An, Vietnam: Remote Sensing and Numerical Modeling Approaches
Authors: Van Duy Dinh , Duc Anh Nguyen Quang , Viet Nguyen Trung , Tanaka Hitoshi
Published: September 2024

Beach erosion and coastal protection are complex and interconnected phenomena that have a substantial impact on coastal environments worldwide. Among the various coastal protection measures, seawalls have been widely implemented to mitigate erosion and protect coastal assets. However, the interrelationship between beach erosion and seawalls remains a critical topic for investigation to ensure effective and sustainable coastal management strategies. Seawalls impact the shoreline, particularly through the “end effect”, where the seawall functions similarly to a groin, causing erosion on the downdrift side relative to the direction of wave approach. This study provides a detailed analysis of the interplay between beach erosion and seawall structures in Loc An, Vietnam, employing both remote sensing and numerical approaches. Sentinel-2 images were employed together with an analytical solution to observe the shoreline change at the Loc An sand spit and to determine input values for the numerical model. Based on the shoreline dynamics, a numerical scheme was employed to study the shoreline evolution after the construction of a seawall. Our findings show that the shoreline evolution can be divided into three stages: (1) The first stage corresponds to the elongation of the sand spit without interference from coastal structures. (2) The second stage shows the effect of jetties on the shoreline, as signaled by the buildup of sand updrift of the jetties. (3) The third stage shows the effectiveness of the seawall, where the shoreline reaches its equilibrium condition. The study provides a quick and simple method for estimating shoreline diffusivity (ε) in situations where measured data is scarce.
Application of GIS Spatial Analysis for the Assessment of Storm Surge Inundation Risks in the Guangdong–Macao–Hong Kong Great Bay Area

Published: September 2024

This study evaluates the storm surge inundation risk in three anthropogenically infilled estuaries—Xichong, Renshan, and Kaozhouyang—located in the Guangdong–Macao–Hong Kong Great Bay Area, China. By integrating GIS spatial analysis with storm surge modeling, we conducted 204 numerical experiments to simulate storm surge inundation under varying typhoon intensities and astronomical tide conditions. Results revealed that coastal terrain plays a crucial role in influencing storm surge levels and inundation extents. Specifically, the pocket-shaped terrain in the Renshan and Kaozhouyang estuaries amplified storm surges, resulting in higher inundation levels compared to the relatively open terrain of Xichong. Furthermore, anthropogenically reclaimed land in these estuaries appear to be particularly vulnerable to storm-induced inundation. Overall, this study underscores the importance of considering coastline morphology and the anthropogenic modifications of coastal terrain in storm surge risk assessments, offering valuable insights for disaster prevention and mitigation strategies. The use of ArcGIS spatial analysis coupled with storm surge modeling, facilitated by high-resolution DEMs, provides a statistical risk assessment of inundation. However, more complex flooding dynamics models need to be developed, particularly when terrestrial bottom friction information, which is heavily modified by human activities, can be accurately incorporated.

A large number of brackish lakes with different levels of hydrobiont development are located on the territory of the Altai Territory. The state of the gammarid stock in shallow lakes depends on background conditions. The purpose of this work is to assess the current state of the reserves of gammarides of brackish lakes and their productivity. The paper presents the results of studies of the state of gammarid stocks in the lakes of the Altai Territory in the period 2022–2023. The seasonal dynamics of quantitative and qualitative indicators of gammarides is described. The size and weight characteristics, age composition and fertility of females in populations of gammarids from different reservoirs are given. It is noted that in the populations of gammarids of Altai lakes, one generation of crustaceans with two litters develops. The dynamics of the distribution of gammarides in the subglacial period and in the period of open water is given. The influence of the main environmental factors on the formation of biomass of commercial invertebrates and the state of their stocks has been traced. A modern assessment of the productivity of brackish lakes in relation to gammarids is given. It is noted that the productivity of reservoirs ranges from low to high classes and can vary over the years depending on environmental conditions. The total reserves of gammarides in the lakes of the Altai Territory in the period 2022– 2023 amounted to 321,7–483,8 tons. Over a long-term period, total reserves range from 162 to 485,4 tons by year, catch varies from 41,3 to 221,1 tons. Criteria have been developed for dividing reservoirs by commercial importance based on gammarid biomass. In the period 2022-2023, reservoirs are classified as commercial, conditionally commercial and non-commercial.

Using Deep Learning for Profitable Concrete Forecasting Methods
Authors: Al-Hinawi Ayat , Alelaimat Radwan
Published: September 2024

: In contemporary construction practices, the precision in forecasting the efficacy of concrete infrastructures plays a pivotal role in ensuring both economical viability and structural robustness. Classical methodologies often falter in encapsulating the myriad variables that intricately govern concrete performance, underscoring the exigency for progressive predictive apparatuses. This manuscript endeavors to fill this lacuna by harnessing a diverse spectrum of computational algorithms, namely Linear Regression, Gated Recurrent Units (GRU), Long Short-Term Memory (LSTM), and WaveNet, and subjecting them to scrupulous evaluation across multifarious metrics to discern their inherent capabilities and constraints. Of paramount significance, WaveNet manifested commendable prowess, registering an R^2 coefficient of 0.884 and an Root Mean Square Error (RMSE) of 23.22. Complementing the technical assessment, this study infuses an economic perspective, elucidating a cogent cost-efficiency rationale advocating the ubiquitous integration of these avant-garde predictive modalities within the construction milieu. Our interdisciplinary stratagem forges a novel conduit for synergetic research, intertwining the realms of civil engineering, computational analytics, and fiscal studies. The empirical results accentuate that machine learning paradigms not only augment predictive precision but also bolster economic viability, heralding them as indispensable instruments in the avant-garde toolkit of construction administration.
El Curandero solar y brujo malero. Ambivalencias del cerro Chaparrí en la mitología de la costa norte peruana
Authors: Lorente Fernández David
Published: September 2024

Este artículo analiza el carácter ambivalente del cerro Chaparrí en la mitología de la costa norte peruana en base al estudio de una serie de mitos que describen los enfrentamientos entre este cerro y el Yanahuanca. Dichos mitos, presentes en distintas fuentes documentales, explican la agencia que se atribuye al cerro y cómo es invocado hoy en las “mesas” o sesiones rituales de maestros curanderos y brujos de una amplia región. Chaparrí es percibido como un “curandero”, asociado con la identidad del Sol, y como un “brujo-malero” que devora las sombras de quienes lo atraviesan y de sus víctimas. Esta doble identidad explica la diversidad y complejidad de prácticas rituales que tienen al cerro como escenario, o en las que su “encanto” es invocado. El enfoque del texto es etnográfico y aborda nociones de agencia, intencionalidad, humanidad,petrificación o la materialidad del cerro Chaparrí, sobre el que no contamos con estudios monográficos en la literatura americanista.
MEDIA IMAGE OF A CORPORATE LEADER: CLASSIFICATION AND DIAGNOSTIC CRITERIA
Authors: Krivonosov A. D. , Rassokhina I. Yu. , Chibisova E. A.
Published: September 2024

The formation of a media image today takes place in the special conditions of the
modern public environment functioning, in the situation of the mediatization of public
space. Diagnostics of the actual media image of a chief executive is considered as an
important part of the organization’s communication audit. Using the example of
publications in the media, social networks and other open sources of information and
mentions of the heads of PJSC Gazprom gas production subsidiaries in the media, the
current characteristics of the media image of the company’s chief executive were
identified and diagnostic criteria for its correction were proposed. It is established
that the image of the head has a significant impact on the image of the organization and
is an integral part of it. One of the important components of a corporate leaders’
professionogram is their media images as necessary components of the leaders’ personal
image. A well-designed image of the head of an organization, including media image, is
able to legitimize high incomes, use the right to make difficult decisions and ensure
the stability of the company's reputation in crisis situations. The presented method of
diagnosing the media image of the chief executive of the company allows us to identify
not only quantitative and qualitative indicators of the media representation of a
person, but also to identify the type of media image. The article highlights such types
of media image (as the image of a public person that has developed in the mass media) as
active, passive, situational / reactive.
THE NOVEL OF V.A. KAVERIN “THE TWO CAPTAINS”: THE TRADITION OF CLASSIC ADVENTURE
LITERATURE
Authors: Lisitsa A. R.
Published: September 2024

In this article the intertextual relations of the V.A. Kaverin’s novel “The Two
Captains” and classics of adventure literature are considered. Among the “literary
ancestors” of Sanya Grigoriev, there are the characters of R.L.B. Stevenson, J.G. Verne,
J.F. Cooper and M. Twain. “Two Captains” is similar to the works of these authors with
their adventure novels by the motifs of oath, escape, discovery of a mysterious
artefact, being an accidental witness of a crime. In addition, some of the Kaverin’s
characters belong to the types of hero-captains and eccentric scientists that are
traditional for foreign adventure literature. The dialogue of the texts is realized in
the novel as a system of reminiscences, which allows a reader to associate the narration
with the stories of characters of significant works and novels, traditionally included
into the range of texts for children and teenagers. It enables to focus not on Socialist
realism but on the adventure nature of the novel. The image of Sanya Grigoriev is
characterized by a twofold nature: he turns out to be both a devoted reader of adventure
literature and the author of his own adventure novel, which he “creates” independently,
telling the reader about his own life and the fate of Captain Tatarinov.
FOLKLORE MEANS IN LITERATURE: PSYCHOLOGICAL PARALLELISM
Authors: Larionova M. Ch.
Published: September 2024

Psychological parallelism (artistic means based on juxtaposition of nature and
individual life) emerged in folklore and further showed its productivity in literary
work. It demonstrates the continuity of a national cultural tradition and broader plot
and figurative potential of literature, compared to folklore. Of all types of
psychological parallelism, outlined by A. N. Veselovsky, one-member parallelism
(employing environmental imagery) and two-member parallelism (equating natural images
and subjective experience) are most frequently observed in 19th century Russian poetry.
The major mode of forming one-member parallelism is a symbol. The structure and
semantics of psychological parallelism are illustrated by A. P. Chekhov's stories. The
analysis of the literary material has shown that two-member and antithetic parallelism
were used. The landscape is not merely a composition but the meaningful element which is
crucial to precisely convey the heroine's emotions and feelings. Natural phenomena are
directly associated with every character. The means plays not only a decorative but
functional role and reveals a strong link between the writer and the national tradition.
INDIVIDUAL CHILD STRATEGY OF ACQUISITION OF MORPHOLOGY AND PERSONAL DEIXIS WHEN
ACQUIRING THE RUSSIAN LANGUAGE (FIRST LANGUAGE)
Authors: Chiglova E. I.
Published: September 2024

Children’s acquisition of morphology in inflectional languages is of relevance in
modern first language acquisition studies. It may go various ways, and the quantity of
these ways depends on morphological affluence of the language. The Russian language has
a developed inflectional system, which causes diversity in children’s individual
strategies while acquiring the language. Various combinations of the so-called syntactic
and morphologic strategies is the reason for strategic diversity among Russian-speaking
children. According to the research, the optimal alternating of the two strategies
benefits for quicker and more efficient acquisition of the category of person and the
entire grammatical system of the language, absence of deictic and grammar mistakes. It
will be the most effective to combine consistent alternation of strategies, starting
with the syntactic strategy with its subsequent transition to the morphologic one. A
denser interlacing of these strategies may cause chaotic acquisition of the language and
incorrect usage of its elements in child speech.
SYSTEM OF SIGNS BY CHARLES SANDERS PEIRCE AS HIS REFLECTION OF STUDY ABOUT
CATEGORIES AND PREDICABILIA: VIEWPOINT OF THE FOUNDER OF SEMIOTICS
Authors: Sitko Yu. L. , Zaharova I. I. , Kuzina O. A.
Published: September 2024

The article attempts to investigate scientific background underlying the system of
signs proposed by Ch.S. Peirce. The study is based on the hypothesis that Ch.S.Peirce
borrowed the principle of systematisation from the Latin translation of “Organon” by
Aristotle published by Julius Pacius in 1584. Having analysed this issue of “Organon”
the author demonstrates that the system of categories and predicabilia by Aristotle was
transformed into a diagram presenting the interconnections between categories as
judgements. Along with that it is shown that Pacius calculated the systems consisting of
more than five notions as elements. Moreover, it is specified that Pacius borrowed the
idea of representing categories in the form of diagrams from Johann Eck. It is possible
to conclude from the investigation conducted that Ch.S.Peirce’s system of signs is
isomorphic to Aristotle’s system of signs in the interpretation of Pacius. The article
also introduces the idea about “the direction of predication” from accidence towards
gender (from right to left) and from gender towards accidence (from left to right),
which opens the perspective for future comparative analysis with semasiological and
onomasiological methods of studying the language.
Advanced Production Technologies in Russia: Assessment of their Impact on Labor Productivity and Efficiency of the Production Process by the Companies
Authors:   Financial University under the Government of the Russian Federation, Bannikov S. A.
Published: September 2024

The urgent need for the transition of the Russian economy to a new technological structure under the influence of the current geopolitical and economic-political situation, as well as the strengthening of import substitution processes, poses the task of a qualitative breakthrough in the introduction of modern processes in industrial production and in the economy as a whole. The gen-eral process of the fourth industrial revolution involves the widespread introduction of robotic, au-tomated systems, and artificial intelligence, linked into single complexes interconnected by commu-nications and cloud storage systems. On the one hand, this process can lead to a massive release of labor resources from traditional blue-collar professions. From another point of view, it creates a large number of new professions to serve new directions and solve new problems. However, the answer to the question of the economic feasibility of introducing such technologies is not clearly positive. And here there can be quite unexpected results when the seemingly obvious benefits from the imple-mentation of certain modern solutions of the sixth technological order for specific organizations or industries are not confirmed. In our work, we use surveys of Russian companies for 2022 to assess the current stage of implementation of production and digital technologies. It has been established that the introduction of modern solutions that lead to the transition to a new technological structure is, in some cases, characterized by a negative effect and lack of improvements in labor productivity. Our observation contradicts the generally accepted idea that automation, digitalization and robotiza-tion will lead to the release of a significant number of workers. Moreover, among the key reasons hindering the implementation of advanced technologies, companies cite the lack of qualified per-sonnel and the inability to hire employees with the required level of knowledge and skills. In other words, we are observing a shortage of highly qualified employees against the backdrop of a rather contradictory effect of innovation in terms of freeing up labor. The introduction of technologies such as artificial intelligence or the Internet of things in most cases is characterized by the absence of a positive impact on the efficiency of internal processes and labor productivity. Our observations lead to the conclusion that there is no prospect of a labor surplus in the labor market due to the ongoing processes of the fourth industrial revolution according to Schwab.

Рассмотрены особенности водно-температурного режима 2022  года в  Центрально-Черноземном регионе. Определены основные отклонения от среднемноголетних значений температуры и влажности воздуха, а также особенности распределения осадков весной и  летом. Выявлено, что отличительной чертой всего вегетационного периода 2022  года является нестабильность как температурного, так и  особенно водного режимов. Отмечена высокая амплитуда суточного перепада температур воздуха превышающая средние многолетние значения. Изучен фенотипический, биологический и  физиологический ответ растений смородины черной на  аномалии водно-температурного режима, в частности, мониторинг динамики фотосинтетической активности растений черной смородины выявил различия по глубине реакции на повреждающее воздействие неблагоприятных погодных условий в зависимости от генотипических особенностей сорта.

The features of  the water-temperature regime in  2022  in  the Central Black Earth region are considered. The main deviations from the long-term average values of  temperature and air humidity, as  well as  the distribution of  precipitation in spring and summer, were determined. It was revealed that a distinctive feature of  the entire growing season of  2022  is  the instability of both temperature and especially water regimes. A high amplitude of daily air temperature differences was noted, exceeding the long-term average values. The phenotypic, biological and physiological response of black currant plants to anomalies in water and temperature conditions was studied; in particular, monitoring the dynamics of photosynthetic activity of black currant plants revealed differences in the depth of the response to the damaging effects of adverse weather conditions depending on the genotypic characteristics of the variety.

Из плодового тела трутового гриба Fomes fomentarius методами суб- и сверхкритической флюидной экстракции этанолом получены хитинсодержащие комплексы с выходом 57—88 % и содержанием хитина до 18,7 %. Оценено влияние продолжительности, температуры и давления экстракции на выход и свойства получаемых хитинсодержащих комплексов, которые охарактеризованы по элементному и функциональному (ИК-спектроскопия) составу. Показана высокая сорбционная емкость полученных комплексов по отношению к основному — метиленовому синему (ло 312 мг/г) и кислотному — конго красному (до 170 мг/г) красителям, что указывает на полиамфолитную природу полученных комплексов — биосорбентов.

Chitin-containing complexes were obtained from the fruiting body of the tinder fungus Fomes fomentarius using sub- and supercritical fluid extraction with ethanol with a yield of 57—88 % and a chitin content of up to 18.7 %. The influence of the duration, temperature, and pressure of extraction on the yield and properties of the resulting chitin containing complexes has been evaluated. Chitin-containing complexes were characterized by elemental and functional (by IR spectroscopy) composition. The high sorption capacity of the obtained complexes in relation to the basic — methylene blue (up to 312 mg/g) and acid — congo red (up to 170 mg/g) dyes is shown. Sorption activity relative to both basic and acid dyes indicates the polyampholytic nature of the resulting complexes-biosorbents.

Проведена оценка эффективности извлечения иода и альгиновых кислот из сухих слоевищ ламинарии японской (Saccharina japonica) субкритической водой при 130, 150 и 170 °С в режиме динамической экстракции. Установлено, что в ходе экстракции происходит полное извлечение иода из слоевищ ламинарии японской, однако в режиме динамической экстракции только около 45 % иодсодержащих соединений переходят в экстракт, остальная часть остается в слизи, формирующейся вокруг частиц ламинарии в ходе экстракции. Полученные экстракты ламинарии японской содержат жирные и фенольные кислоты, спирты, углеводы. Мармелад, изготовленный на основе субкритического водного экстракта ламинарии массой около 6 г, содержит около 20 суточных доз иода и может применяться в качестве продукта функционального питания.

Within the framework of this work, the efficiency of extracting iodine and alginic acids from dry thalli of laminariya japanese (Saccharina japonica) with subcritical water at temperatures of 130, 150 and 170 °С in the dynamic extraction mode was evaluated. It has been established that during extraction, iodine is completely extracted from the thallus of laminariya japanese, however, in the dynamic extraction mode, only about 45 % of iodine-containing compounds pass into the extract, the rest remains in the mucus that forms around the particles of laminariya during the extraction process. The obtained extracts of laminariya japanese contain fatty and phenolic acids, alcohols, carbohydrates. Marmalade, made on the basis of a subcritical water extract of kelp weighing about 6 g, contains about 20 daily doses of iodine, can be used as a functional food product.

20. yüzyılın ortalarından itibaren sanayileşme devrimi sonrası yaşanan hava, su ve toprak kirliliği vb. çeşitli çevre sorunlarının önlenmesi, etkilerinin azaltılması ve sürdürülebilir gelişmenin sağlanmasına yönelik çalışmalar, 1970li yıllardan günümüze dek iklim değişikliği ile içeriği daha da genişleyen bir şekilde uluslararası platformda çözüm aranan konulardandır. Ülkemizde su kaynakları iklim değişikliği, artan nüfus sayısı, hızlı kentleşme sebepleri başta olmak üzere hızla tükenmektedir. Uluslararası göstergelere göre Türkiye su stresi altındaki ülkeler arasındadır. Bu çalışmanın amacı ülkemizde iklim değişikliği bağlamında özellikle su kaynaklarının korunarak geliştirilmesi, sürdürülebilir kullanımı, verimliliğin arttırılması ve bunlara ek olarak kuraklık, sel ve taşkın benzeri doğal afet risklerinin azaltılmasına yönelik “suya duyarlı kentsel planlama ve tasarım” çalışmalarının geliştirilmesinin gerekliliğini ortaya koymaktır. Çalışmada iklim değişikliği bağlamında su kaynaklarının üzerinde artan baskılar sebebiyle uluslararası tartışmalar ışığında, yenilikçi yaklaşımlarla ele alınmasının önemi ve literatürde suya duyarlı kentsel planlama ve tasarım yaklaşımlarının gelişen içeriği üzerinde durulmuştur. Türkiye’de suya duyarlı şehirler oluşturulması koşulları mevcut yasal ve yönetsel yapı içerisinde irdelenmektedir. Ülkemizde yapılan değerlendirmeler ışığında su kaynaklarının artan baskılar sebebiyle yok olmaya başlaması sebebiyle sürdürülebilir, verimli ve akılcı kullanımı zorunludur.

Bu bağlamda yasal ve yönetsel yapının AB’ye uyum süreci içinde gelişmesi ve fırsat sunması sebebiyle uygulamaların kamu eliyle özendirilerek teşvik edilmesi, kurumlar arası ve toplum iş birliği içinde gerçekleştirilmesi gerekmektedir.
Sodium–potassium–niobate based piezoelectric ceramics: processing—microstructure—properties
Authors: Malič Barbara
Published: September 2024

Sodium potassium niobate (KNN) and KNN-based ceramics are considered viable alternatives to lead-based piezoelectric ceramics. Their chemical composition is the key to their phase transitional behaviour, which determines their functional properties. On the other hand, the microstructure is another factor that crucially contributes to shaping the properties of ceramics. The review addresses the synthesis of the perovskite solid solution as well as the issue of chemical homogeneity depending on the choice of the reagents. In sintering, the importance of stoichiometry in densification and microstructure evolution is discussed. Phase boundary engineering, which has been effective in tailoring the functional response of KNN-based ceramics, is discussed from the viewpoint of material chemistry and processing that may contribute to chemical homogeneity. Finally, consolidation approaches with a lower thermal budget are addressed.

Objective: The main objective is to evaluate the effectiveness of the new combination of two drugs i.e. Tropicamide, Phenylephrine with
Flurbiprofen, and tropicamide with phenylephrine to achieve maximal pupil dilation in cataract patients. Methodology: A prospective
observational study was conducted, and comprehensive literature was studied on comparing the mydriatic effect between Tropicamide with
Phenylephrine and Flurbiprofen vs. tropicamide and phenylephrine in cataract patients over 6 months (July 2023–December 2023). A total of 18
subjects were recruited for our study and were administered tropicamide and phenylephrine with urbiprofen, tropicamide, and phenylephrine.
Results were recorded by comparing both drugs for pupilar dilation and sustainability. Results: Among 128 patients (age range 20-79 years), 64
were randomized into the tropicamide with phenylephrine and urbiprofen group and 64 into the tropicamide with phenylephrine drug group.
baseline pupil sizes were in the range of 2-2.5mm in both groups the mean pupil size at 60min were 6.6mm and 6.5mm in the tropicamide with
phenylephrine and urbiprofen and tropicamide with phenylephrine drug groups, respectively. the mean sustainability was 5.2 hours and 4.2 hours
in the tropicamide with phenylephrine and urbiprofen group and tropicamide with phenylephrine group. Conclusion: It has been concluded that
the combination of 0.03% urbiprofen, 5% phenylephrine, and 0.5% tropicamide is more effective for the dilatation of the pupils than using only
5% phenylephrine and 0.5% tropicamide. This combination produces quicker results within 60 minutes.
