AIM: To investigate the underlying mechanism of dry environment (autumn dryness) affecting the lacrimal glands in rats.
METHODS: Twenty Sprague-Dawley rats were randomly divided into two groups. The rats were fed in specific pathogen free environment as the control group (n=10), and the rats fed in dry environment as the dryness group (n=10). After 24d, lacrimal glands were collected from the rats. The tissues morphology was observed by hematoxylin-eosin (HE) staining. Tandem mass tags (TMT) quantitative proteomics analysis technology was used to screen the differential expressed proteins of lacrimal glands between the two groups, then bioinformatics analysis was performed. Further, the immunohistochemical (IHC) method was used to verify the target proteins.
RESULTS: In dryness group, the lacrimal glands lobule atrophied, the glandular cavities enlarged, the sparse nuclear distribution and scattered inflammatory infiltration between the acinus were observed. The proteomics exhibited that a total of 195 up-regulated and 236 down-regulated differential expressed proteins screened from the lacrimal glands of rats. It was indicated that the biological processes (BP) of differential expressed proteins mainly included cell processes and single BP. The cellular compositions of differential expressed proteins mainly located in cells, organelles. The molecular functions of differential expressed proteins mainly included binding, catalytic activity. Moreover, the Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis showed that the differential expressed proteins mainly involved lysosome, complement and coagulation cascade, and ribosome pathway. The IHC result verified that the up-regulated expression proteins of Protein S100A9 (S100A9), Annexin A1 (Anxa1), and Clusterin (Clu) in lacrimal glands of rats in dryness group were higher than control group.
CONCLUSION: The up-regulated expression proteins of S100A9, Anxa1, and Clu may be the potential mechanisms of dry eye symptoms caused by dry environment. This study provides clues of dry environments causing eye-related diseases for further studies.

Desakralizacja miejsc kultu. Przypadek francuski
Authors: Wojciechowski Grzegorz
Published: February 2024

Miejsca kultu to przestrzeń, która ma pomóc w nawiązaniu relacji i w spotkaniu z Bogiem. Jest to miejsce wyłączone z użytkowania świeckiego. Jednak nie jest pozbawione konieczności utrzymania i zabezpieczenia właśnie w wymiarze świeckim. Ideałem jest, gdy raz ustanowione miejsce kultu jako takie trwa niezakłócenie przez lata. Nie jest to jednak możliwe w każdym przypadku. Kościoły i kaplice niszczeją tak przez działania człowieka (chociażby wojny), jak i przyrody (kataklizmy). Niebezpiecznym czynnikiem jest także upływ czasu wraz z laicyzacją społeczności odpowiedzialnej za utrzymanie świątyni. Szczególnym przypadkiem jest Francja, gdzie sytuacja własnościowa Kościoła powoduje, że często można znaleźć ogłoszenie o możliwości kupna kościoła lub kaplicy. Społeczność lokalna zaś, najczęściej gmina, musi podjąć decyzję o sprzedaży budynku, który tylko obciąża budżet. Celem artykułu jest przedstawienie sytuacji desakralizacji miejsca kultu we Francji z perspektywy zarówno prawa kościelnego, jak i francuskiego.

Authors: Huang Shiyou , Gao Yuxin , Yang Yuying , Wang Lulu , Han Jining
Published: February 2024

Organizational justice pertains to the perception of fairness experienced by individuals within an organization, encompassing four dimensions: procedural justice, distributive justice, leadership justice, and informational justice. To obtain the data a questionnaire survey on 432 primary and secondary school teachers was conducted to understand their sense of organizational justice, professional achievement, and work engagement. The research results found that (1) there is a significant positive correlation between organizational justice and teacher work engagement, with organizational justice also serving as a substantial predictor of this engagement level; (2) the sense of professional achievement is significantly positively correlated with the level of teacher work engagement, and it significantly predicts the level of teacher work engagement; and (3) organizational justice indirectly affects teachers' level of work engagement through the mediating effect of professional achievement. Research suggests two strategies to enhance primary and secondary school teachers' sense of organizational justice and professional achievement, thereby improving their work engagement levels.

Published: February 2024

The number of vehicles is increasing every year, and along with it, the number of traffic violations is also rising.. Traffic violations are one of the causes of traffic accidents. Currently, traffic violation detection still uses conventional methods, involving the police to take action. Preliminary research on traffic violation detection by several researchers mostly uses the Yolo Method. The study aims to design a traffic violation detection system for two-wheeled vehicles using the Convolutional Neural Network (CNN). In this research, the CNN method was used with the Faster RCNN architecture. Faster R-CNN is composed of convolution layers, Relu, and pooling layers which are used to extract features from images. An image in the size of 3264 x 1836 pixels, with the type of marking violation and helmet use was used as a sample. The number of images used was 660 images with 600 images for training and 60 images for testing. The system will detect traffic violations on two-wheeled vehicles, namely helmet use violations and road marking violations. This traffic violation detection system for two-wheeled vehicles produces the highest accuracy, namely 85% with a maxpooling kernel size value of 1x1, stride 1 and a learning rate of 0.003. This research has the potential to be applied to areas that are less accessible to the police, because the system will record and analyze violations.

Influenza, surpassing all other respiratory diseases in both morbidity and mortality, annually triggers seasonal epidemics responsible for approximately 500,000 global deaths. Mathematical epidemic models serve as valuable tools for forecasting potential outbreaks and predicting the trajectory of the disease. This paper represents a comprehensive SEIRVS model tailored to the context of Influenza transmission dynamics in North Macedonia. In this paper the classical Susceptible- Exposed- Infectious- Recovered (SEIR) model is enhanced by incorporating vaccination and a death compartment while examining their impact on the spread of Influenza through the population. Simulations are conducted using data from the 2022/2023 season, focusing on a case study of North Macedonia. The simulations were conducted utilizing both the actual vaccination rate in N. Macedonia for that season and an increased vaccination rate to observe the influence of vaccination. The simulation results emphasize the need to increase the vaccination rate. The findings contribute valuable insights for public health planning and policy making.

Published: February 2024

The article discusses a fundamental problem in the shipbuilding industry related to the repair of critical and expensive components directly related to the operation of ships in the global fleet. Methodology and technology for repair by welding of workpieces made of 40X steel have been developed and applied. Hardfacing electrodes of the brands OK 83.28 and OK 61.20 were used. The developed welding technologies include both buffered and non-buffered layers. For one of the specimens, preheating to a temperature of 200 degrees Celsius was performed, which proved to be optimal for the metal. The measured macro stresses are below the elastic limit of the examined metal. The measured residual stresses are insignificant at +62 MPa. The microhardness results show an increase in microhardness to about 450HV in the weld metal zone. The dry friction wear test performed on the welded layer showed a relatively uniform metal loss in both specimens due to the slight increase in temperature.

Published: February 2024

To ensure a rapid and consistent design of Photovoltaic (PV) modules, the presence of an effective simulator is essential for assessing the behaviour of the PV cell when subjected to rapid or partial changes in temperature, irradiance, and parasitic resistance. The prevailing approach for modelling involves utilizing an equivalent circuit that encapsulates both nonlinear and linear mechanisms. The study introduces an eleven-parameter quartic model for the simulation and modelling of a PV unit. The model takes into account the equivalent circuit constraints of the PV cell and validated by solving the non-linear voltage equation. The examination concentrates on three pivotal junctures: open circuit, maximum power point, and short circuit. These key points are crucial for comprehending the operational characteristics of the PV module in typical conditions. The proposed quadruple diode model has been demonstrated to outperform the lower-order diode models in terms of performance and accuracy. To validate the strength and precision of the developed model, the model was simulated using the specifications of PV panels, and the outcomes were compared with the recorded values obtained from the lower-order models.The model was developed and tested using standard mathematical equations for PV cells within the MATLAB/ Simulink environment.

Published: February 2024

The understanding of the metaverse is currently expanding, and several interpretations and implementations may be present. The many metaverse iterations have distinct components and capabilities, which have the potential to evolve and enhance over time in tandem with technological advancements and evolving user requirements. The metaverse has emerged as a widely discussed subject of public interest, with individuals and organizations alike contemplating its potential applications. However, a prevailing misperception persists over its fundamental comprehension. The concept of the metaverse is often misconstrued as solely referring to a virtual world; nevertheless, it encompasses more than simply a virtual realm. Three other categories can be classified as constituting the metaverse. The metaverse encompasses four distinct categories, each characterized by unique aspects that may or must diverge from one another. The elements play a crucial role in the development of any metaverse kind. This work aims to provide a valuable contribution by offering a comprehensive analysis of the constituent features of various metaverse types. Its purpose is to assist anyone interested in studying or implementing a certain metaverse type by fostering a deeper understanding of its core aspects.

Published: February 2024

Abnormal quality and composition of bone mineral bonds in the spine are found in many patients with cases of idiopathic scoliosis. The data shows that poor bone quality promotes thoracic spine degenerative disc swelling and physiological anomalies. Implants in the form of pedicle screws, rods, and connectors are one of the measures for scoliosis correction. When the pedicle screws are taken out after some use poor bone quality remains. In this study, fixation strength analysis will be carried out through tensile testing of bone joints and pedicle screws with variations in bone quality. Two specimen materials were used for approach analysis: polylactic acid (PLA) and bovine backbone. Pedicle screws are classified into three types: cylindrical, conical with a single thread, and double cylindrical screws. Tensile testing revealed that PLA specimens with pedicle screw variants provided the maximum force of 7.4 N and 8.31 N with double screw cylindrical implants at PLA 70:30 and PLA 40:60. A comparison of PLA specimens with a series of cylindrical screws to double-screw cylindrical screws yielded a displacement increase of 79.6%, whereas conical screws yielded a displacement increase of 222.3%. Fixation with double-screw cylindrical screws greatly increases tensile strength. However, the conical pedicle screw model with connecting rods gives greater fixation strength.

Authors: Nguyen Van Nhanh , Nguyen Anh Xuan , Nguyen Dinh Tuyen , Le Huu Cuong , Nguyen Van Phuc
Published: February 2024

Mechanical parts on ships and automobiles are diverse in shape, size, and working conditions. They operate with static, cyclic, and shock loads in various environments at low and high temperatures. Therefore, materials need to be highly durable to ensure the reliability of parts and structures on ships and automobiles. Currently, materials used in the shipbuilding and automotive industry are diverse, and steel is commonly used. Therefore, the shipbuilding and automotive industry requires increasingly higher steel mechanical properties. Among the advanced high-strength steel families, low Mn steels with phase change, thanks to the plastic deformation process, are steel lines with high durability, flexibility, and good fatigue resistance. Therefore, low Mn steel is suitable for manufacturing load-bearing parts that undergo deformation to create the required shape. This work presents general studies on the effects of some elements, such as Mn, Si, and C, on the microstructure and mechanical properties of TRIP steel. This article also presents the mechanism of the phase transformation process of TRIP steel when heated and cooled under some conditions, the thermodynamic basis of the formation of TRIP-type bainitic ferrite steel structure, and the influence of C, Mn, and Si on the formation kinetics of TBF steel structure. Through these review studies, the article synthesizes and identifies a number of phase transformation mechanisms for steel; the influence of certain alloying elements on the microstructure and mechanical properties of steel has been determined.
Household food waste—the origin, level, structure and methods of prevention
Authors: Pierański Bartłomiej , Smutka Luboś
Published: February 2024

Food waste is one of the major problems that humanity needs to solve. The gargantuan amount of food wasted each year, estimated at around 1 billion tonnes, creates a range of environmental, economic and ethical problems. Unfortunately, food is wasted to the greatest extent by households. To a Lesser extent, food is wasted by producers or intermediaries. Therefore, the aim of this article is first and foremost to identify the causes of food waste by households. To do this, a conceptual framework has been adopted. It assumes that household food waste originates in three predictable stages—when shopping, storing and serving. In other words, households waste food because they do not prepare the food they purchase, they do not serve the food they prepare, and they do not consume the food they serve. The considerations in the paper are based on the available literature and secondary data.

Published: February 2024

This study provides a comparative analysis of the budget limits of the Commonwealth of Independent States members, focusing on fiscal responses to the COVID crisis and options for improving the structure. The methodology comprised a statistical approach based on assessments of macroeconomic indicators for 2020–2021, as well as world rankings and several measurement systems. The following new budgeting principles were formulated as a result of the comparative analysis of public administration. The proposed principles focus on monitoring, assessing, and forecast data of long‑term sustainability management and other fiscal risks. The proposed budgeting principles could provide a country with the new opportunities needed to expand its potential during further economic advancement in global politics. The central result of this work is a renewed approach to budget management using data on the actual economic situation and adaptability to changes. The proposed budget management scheme lays the foundation for the future development of a country’s potential and aligns with the priority goals of the CIS member states in terms of democracy. The value of this research lies in presenting and summarizing the analysis of the budget management system and the detailing of budgetary policies to identify and reflect the political priorities of countries. This helps formulate recommendations and suggestions for improving the budgetary process, achieving a balanced distribution of resources, and attaining strategic development goals. The practical application of the findings will allow budget policy specialists, economists, and statisticians to become familiar with the changes in the institutional landscape amid COVID–19 and assess the situation in their region through the prism of administrative sovereignties.
The Gender Gap in the Visegrád Group Countries Based on the Luxembourg Income Study
Authors: Jędrzejczak Alina , Trzcińska Kamila
Published: February 2024

Gender equality is a fundamental human right and one of the core values of the European Union (EU). Great efforts have been made to defend this right and to promote gender equality within the member states and around the world. However, there are still significant differences between men and women, especially in terms of income. The main objective of the paper is to compare income distributions for gender groups across four Central European countries, Poland, Slovakia, Czechia and Hungary, i.e., the members of the Visegrád Group (V4). These countries share similar histories and similar economic development, but there are substantial differences between their approaches to economic reforms, including labour market policy. This, in turn, is reflected in different income distributions and income inequality patterns. There is a debated research issue regarding the methodology of measuring the gender gap – the traditional methods based on comparing means and medians seem unsatisfactory as they do not consider the shape of income distributions. The paper’s novelty lies in the application of the relative distribution concept, which goes beyond the typical focus on average income differences toward a full comparison of the entire distribution of women’s earnings relative to men’s. In the paper, we implement a parametric approach for estimating the relative distribution, which allows us to compare and visualise the “gap” between the gender groups at each distribution quantile. The basis for the calculations was the microdata from the Luxembourg Income Study (LIS). The statistical methods applied in the study were appropriate to describe the gender gap over the entire income range. The results of the empirical analysis helped to reveal similarities and substantial differences between the countries.
Food Production in the Cities of Tomorrow. The Results of International Questionnaire Surveys
Authors: Burchard‑Dziubińska Małgorzata
Published: February 2024

The considerations in this article have three goals. The first is to obtain information on the practical experience of young urban residents who use urban horticulture and agriculture products. The second is to determine the readiness to practice such production independently in the future. The third is to identify the environmental benefits (ecosystem services) related to urban horticulture and agriculture indicated by the respondents. In this case, it was about examining the “environmental intuition” of people who are not professionally related to natural and agricultural sciences. The comparative study concerned students from Brazil, China, India, Mexico, Poland, and a group of seven countries from the European Union. In total, respondents came from 29 countries. The collected data were used to compare the approach to urban horticulture and agriculture and their produce represented by respondents from different countries and cultural circles and to formulate conclusions on how to use the related potential to support sustainable urban development.

Published: February 2024

This article aims to verify the development prospects of the Pan‑European Personal Pension Product (PEPP) in the European Union (EU). It focuses on the relationship between the quality of domestic public pension schemes and household savings for old age in the EU member and candidate countries. The study was conducted in two stages. The first stage examined the interrelationship between public pension schemes and household savings based on Pearson’s correlation coefficients. In the second stage, sub‑samples of countries with high and low‑quality public pension schemes were identified using hierarchical cluster analysis. The results showed significant links between households’ obligatory and voluntary saving for retirement in both samples. However, the study recognised the internal diversity of countries in terms of households’ preferences for the types of financial assets. Based on these findings, conclusions about the development potential of PEPP are drawn. The best prospects are identified for Croatia, Cyprus, France, Greece, Hungary, Poland, Portugal, Romania, Slovenia, Spain, and Turkey. In most of these countries (except for France, Hungary, Romania, and Spain), the PEPP could serve as an alternative to household liquid assets. However, in Croatia, France and Italy, it was recognised as competing with existing domestic retirement and life insurance products, which may negatively impact its development. This is the first comprehensive study of the prospects of PEPP in a large group of countries. The results provide socially essential knowledge as they address the role of private savings in supplementing households’ future income from public pension schemes, considering the availability of a new product such as PEPP.
Globalny rynek sztuki w obliczu kryzysów 2008 oraz 2020 roku
Authors: Niedzielska Anna
Published: February 2024

Artykuł dąży do odpowiedzi na pytanie o to, jak globalny rynek sztuki zareagował na dwa największe kryzysy ekonomiczne początku XXI wieku. Pierwszy miał źródło w sektorze bankowym, drugi był związany z epidemią COVID-19. Oba wpłynęły na handel dziełami sztuki, wymuszając bezprecedensowe zmiany. W obu przypadkach, po początkowej fazie załamania i paraliżu, rynek sztuki szybko odzyskał równowagę, a wartość obrotów wracała do poziomu sprzed załamania. Warto wspomnieć, że proces ten następował wyraźnie szybciej niż w przypadku pozostałych form inwestowania. Instytucje rynku sztuki, wcześniej uznawane za niezwykle tradycyjne i konserwatywne, zdecydowały się na doniosłe i szybkie przekształcenia, co dowiodło ich elastyczności i otwartości na zmiany. Czynnikiem, który przyspieszył wyjście światowego rynku sztuki z recesji roku 2008, była wzmożona aktywność kolekcjonerów chińskich i włączenie do obiegu aukcyjnego i galeryjnego rynków wschodzących. Wraz z rozprzestrzenianiem się epidemii COVID-19 rynek sztuki stanął w obliczu kolejnego kryzysu, który prawie całkowicie uniemożliwił mu funkcjonowanie w tradycyjnej formie. Dramatyczna sytuacja szybko zmobilizowała rynek sztuki do przyjęcia gwałtownej rewolucji cyfrowej. Dzięki nowym technologiom, które całkowicie zmieniły jego wcześniejszy model funkcjonowania, rynek sztuki przetrwał, a wkrótce osiągnął wzrost. Również kolekcjonerzy zaakceptowali zmiany technologiczne – szczególnie dotyczyło to pokolenia urodzonego w latach 80. i 90. XX wieku. To właśnie ci nabywcy stali się niezwykle aktywni na rynku sztuki i to oni będą kształtować jego przyszłość. Omawiane wydarzenia nie zachwiały pozycją dwóch największych rynków sztuki na świecie: Stanów Zjednoczonych i Wielkiej Brytanii, ale pozwoliły dołączyć do ścisłej czołówki trzeci rynek – Chiny.
Remiksowanie iluzji. Krzysztofa Wieczorka droga od grafiki do malarstwa
Authors: Leśnikowski Dariusz
Published: February 2024

Krzysztof Wieczorek, zmarły w 2021 roku łódzki artysta, był wybitnym grafikiem. W swoich poszukiwaniach twórczych ujawniał naturę dociekliwego współczesnego manierysty. W swoich pracach poddawał „obróbce” między innymi cytaty z obrazów i grafik Herculesa Seghersa. Fragmenty krajobrazów stworzonych przez holenderskiego twórcę uzupełniały pejzaże zakomponowane przez polskiego artystę.

Wieczorek dopełniał obraz dzięki różnym, graficznym i malarskim, ingerencjom. Zabiegi te zmierzały ku zróżnicowaniu odbitek z nakładu, dzięki czemu nabierały one charakteru unikatowego. Krzysztof Wieczorek wykorzystywał w swojej pracy wykonane wcześniej matryce, także ich fragmenty, zestawiając je w rozmaitych konfiguracjach. Możemy tu mówić o swoistym „remiksowaniu” artystycznych komunikatów. Wieczorek tworzył warianty obrazów, a nawet ich sekwencje. Sukcesywne modyfikowanie podłoża graficznego dokonywało się w dużej mierze poprzez złożone działania o charakterze malarskim.

W dziełach Wieczorka podkład stanowi zarówno jednorodna odbitka graficzna, jak i ich kolaż. Części składowe mogły być wykonane w akwaforcie, akwatincie, mezzotincie, suchej igle, czy pochodzić z wydruku komputerowego. Wybór techniki (lub technik), stopień destrukcji matrycy (dokonujący się na przykład poprzez chropowacenie, rytowanie i trawienie powierzchni) determinował do pewnego stopnia dalsze poczynania twórcy. Podobnie jak wykorzystanie kolorowych papierów do druku. Artysta eksperymentował także z podłożem, wykorzystując do swoich kompozycji powierzchnie płócienne, tekturowe czy drewniane. Podkład graficzny był poddawany zabiegom malarskim. Twórca kładł na powierzchni grafiki warstwę farby akwarelowej, olejnej czy akrylowej. Impregnował powierzchnie werniksami.

Istota poszukiwań podejmowanych przez Krzysztofa Wieczorka kryje się oczywiście w zachowania równowagi pomiędzy aspektami technicznymi i technologicznymi, a walorami estetycznymi dzieła oraz wyznaczanymi przez elementy świata przedstawionego treściami. W swoich poszukiwaniach twórca odnosił się do skomplikowanych relacji między tym, co graficzne, a tym, co malarskie. Szukał uniwersalnego, integralnego języka komunikacji wizualnej.

The purpose of the article. The study aims to analyze how these special rules of financing during the pandemic affected the financial situation of hospitals in Poland.
Methodology. We analyzed a sample of 86 Polish hospitals from 2019 to 2021. The financial condition is assessed based on financial ratios and the synthetic measure M1. We employ the Kruskall-Wallis test to confirm the differences between the values of financial ratios in the analyzed period.
Results of the research. We confirm that due to the special rules and financing, combined with underperformance, the financial condition of Polish hospitals has slightly improved – especially in the case of operating margin, EAT to debt ratio and ROA.
What is Known About Capacity and Coordination of Social Assistance Programmes in Crisis Situations?
Authors: Slater Rachel , Haruna Ella , Baur Daniela
Published: February 2024

This paper reviews the literature and documented evidence on capacity and coordination issues in crisis situations, where social protection and humanitarian assistance intersect. The paper finds that while there is a burgeoning literature that mentions capacity and coordination, very little of this focuses on crisis situations. Although both terms are mentioned frequently, they are rarely defined or robustly and systematically assessed. The little literature that does exist points to a substantial knowledge gap on both the ways in which capacity and coordination deficits undermine the delivery of social assistance in crisis situations and what can be done to overcome these deficits. Frameworks that could be useful in exploring these questions in crisis situations are identified including those that differentiate between technical and functional elements of capacity, and between technical, political, social and behavioural aspects of coordination.
INVESTIGATION OF STRUCTURAL AND REACTIVITY PROPERTIES OF SOME HALOGENATED PIPERAZINES

Published: February 2024

The chemical and biological activities are strongly related to the molecular structures and the media to which the molecules were subjected. Therefore, it is crucial to know the behaviors of molecular systems in the examined solvent media and their structural and reactivity properties. In the framework of this study, molecular and reactivity properties of some halogenated piperazine derivatives were undertaken by using the density functional theory. It was observed that halogen atoms have considerable effects on the behavior of piperazine molecule. Further, the atypical characteristic of fluorine affecting conformational preference is observed for di-halogenated piperazines with the same halogen atoms.
ANALYSIS OF HIGHLY POLAR PESTICIDES IN FOODS OF PLANT ORIGIN VIA LIQUID CHROMATOGRAPHY/MASS SPECTROMETRY

Pesticides in foods of plant origin are becoming a major issue due to their intensive use in agriculture. Since pesticides are potentially harmful to the environment and consequently to human health through the consumption of pesticide contaminated foods. The European Community and also the Ministry of Agriculture and Forestry in Turkish Republic established maximum residue levels (MRLs), based on the assumption that good agricultural practice is applied at the use of pesticides in farming, for pesticide residues in food of plant origin. As a consequence food commodities have to be controlled to assure the non-violation of the MRLs. Thus an appropriate control of their residues in samples has to be operated.

In this study, we inferred the analytical methods for highly polar pesticides in foods of plant origin via LC-MS/MS after extraction with acidified methanol according to QuPPe (Quick Polar Pesticides) method. Optimization of 13 highly polar pesticides was carried out with LC-MS/MS Q-Trap. After the optimization process has been completed, the samples to be taken according to the SANTE (Guidance document on analytical quality control and method validation procedures for pesticide residues and analysis in food and feed) guidelines have been carefully selected, including high water, high acid/high water, high sugar/low water, high oil/low water and high starch/low water content and difficult or unique commodities. Six samples carefully selected according to the SANTE guideline were carried out at two different concentrations, one of at the detection limit which is 10 µg/L. At the end of the studies, it was found that the RSD criteria for repeatabilitiy was below 20 % for all substances. In addition, the recovery value for all substances was in the range of 70 – 120 %. As a result, 13 different polar pesticides can be analyzed in product groups of plant origin via LC-MS/MS method developed by using hypercarb column.
ROGUE WAVES IN DISCRETE KDV EQUATION
Authors: TOMBULOĞLU Semiha
Published: February 2024

This study considers an array of waveguides described by a discrete KdV equation. Rogue wave solutions numerically derive for the dKdV equation under periodic and non-vanishing boundary conditions. When solving the dKdV equation with periodic boundary conditions, a discrete rogue wave occurs due to shock front breaking. Additionally, the dKdV equation has been solved numerically under non-vanishing boundary conditions, and it has been found that the rogue wave amplitude depends on the ρ_0 parameter.
