Maye qaz doldurma stansiyalarında müxtəlif cür nasos və kompressorlardan istifadə oluna bilər.Bu kompressorların texnoloji sxem və işləmə prinsipinə əsasən müasir tələblərə cavab verməsi çox önəmlidir.Hal-hazırda Azərbaycan Respublikasının maye qaz doldurma stansiyalarında avadanlıqlar arasında Sovet dövrünə aid olan kompressorların da fəaliyyət göstərir.
Keçmiş zamanlarda bu kompressorların işləmə sxemləri əlverişli hesab edilsə də,illər keçdikcə texnologiyanın inkişafı bu avadanlıqların daha az səmərə gətirdiyini ortaya çıxardı. Ən son texnoloji avadanlıqlarla təchiz olunmuş kompressorların, həmçinin nasosların yığcam və çoxfunksiyalı tərtibatı əlverişli və faydalıdır. Bu cihazlar işləyərkən onların vibrasiya dərəcəsi, qabarit ölçülərinin seçilmiş məkanlara daha çox uyğunlaşması, proses zamanı aşağı yağ sərfiyyatı və aşağı sıxılma xərcləri, istənilən suqəbuldedici təzyiqdə işləməsi onu daha da optimallaşdırır.Yeni Avropa avdanlıqlarından istifadə edərək həm enerjiyə qənaət etmiş oluruq,həm də maksimum rahatlıq və digər imkanlardan istifadə edirik.
Avropanın müasir kompressorlarının dizaynı , analoqlardan fərqli olaraq, kompressor mərhələlərinin boşaldılmasıdır və bu, kompressorun mexaniki hissələrinə metan üçün quraşdırmanın ümumi ölçülərini və yükü azaltmağa imkan verir. Optimal stansiya performansı, maksimum rahatlıq və tuning imkanını təmin edən qabaqcıl texnologiyalarla təchiz edilmişdir.

RESEARCH OF THE PROCESS OF LOW TEMPERATURE CONCENTRATION OF FOOD RAW MATERIALS FOR ZEFIR MANUFACTURE
Authors: Polievoda Yurii , Solomon Alla , Bondar Mariana
Published: May 2022

The article investigated the recipe composition and method of low-temperature concentration of fruit and vegetable puree with the content of components: 20% apple, 20% pumpkin, 15% beet, 15% cranberry, 15% hawthorn. Concentration of puree is carried out in a rotary evaporator to a dry matter content of 50% at a temperature of 50… 56 ° C under vacuum. At the same time, the processing time was reduced by 1… 2 min, which is many times less compared to traditional single-hull vacuum evaporators (60… 90 min). Reducing the temperature effect of concentration helps to increase the organoleptic and physicochemical parameters of the resulting paste. To establish the effect of the contribution of each component on the structure of the paste, the structural and mechanical properties of the puree of each raw material and concentrated semi-finished products were studied. The developed paste has increased strength of the structure with a value of dynamic viscosity - 394 Pa ∙ s, which is 2.5 times more than the control sample. The developed blended fruit and vegetable paste has an increased content of physiological and functional ingredients and the best organoleptic characteristics in contrast to the control version (apple paste).
It is established that partial replacement of apple puree (up to 75%) in the prescription composition of marshmallows with the developed multi-component fruit and vegetable paste gives the product original properties. An increase in the value of the dynamic viscosity of marshmallows with a content of 75% replacement of apple puree with the developed paste compared to the control sample (marshmallows without additives) from 408 Pa ∙ s to 908 Pa ∙ s. The color of the marshmallow mass with 75% replacement of apple puree is bright pink with a wavelength of 596.7 nm and a brightness of 62.3%. The obtained data allow to improve the quality of original marshmallows by adding fruit and vegetable semi-finished products with increased functional properties.

Sugar production is one of the most complex and energy-intensive. Conditions of high competition of modern reality bring to the fore such indicators as quality, energy consumption, cost. Such conditions dictate the need to apply the latest scientific advances in the automation of sugar production technologies.
The automation of the sugar industry ensures high-quality, efficient operation of all technological sections of the sugar plant only through a comprehensive approach to solving this problem. One of the main problems in creating the ACS TP of the sugar industry is the stabilization of the flow line of the main product of sugar technology, as well as maintaining optimal levels of product stock in intermediate (buffer) collections of sugar technology. The technological complex of the sugar industry enterprise consists of areas of procurement, storage, preparation of raw materials for processing, departments of juice production, purification of diffusion juice, areas of finished product production, storage and auxiliary production.
Increasing productivity in sugar factories, developing new technology to improve quality, increase the efficiency of sugar industries that require renewal, as well as improving management systems using modern measuring and automation tools.
Automation of technological processes with the use of automated complexes, machines, mechanisms, modern means of automation and computer technology is one of the main directions of scientific and technological progress in all sectors of the economy.
The analysis and development of the automated system of dispatch control of the drying process of pulp in sugar production is carried out in the work. The system is based on SCADA - Trace Mode 5.10 system manufactured by AdAstra. The result is a fully functional system that can be used in sugar production and the advantage of its implementation is to increase efficiency compared to existing systems.
MODELLING OF WORKING PROCESS OF EQUIPMENT WITH HYDRAULIC DRIVE FOR SEPARATION OF DAMP DISPERSIVE MATERIALS
Authors: Sevostianov Ivan , Ivanchuck Yaroslav
Published: May 2022

A task of introduction of separation processes of damp dispersive materials are very actual for food and processing industry of Ukraine and other countries, because its solution will allow to resolve by most effective way a problem of utilization of such waste as alcoholic bard, beer pellets, beet press, coffee and barley slime. In most cases this waste is poured out in nearest reservoirs or on ground and that leads to environment pollution. But after separation from the waste of the liquid phase (waste dehydration) its hard phase can be used as a valuable additive to agricultural fodders or as a high calorie fuel. By article’s authors notion the most prospective method of separation of the damp dispersive waste is mechanical dehydration, that provides high productivity of the working process, low consumption of energy (in 240 – 800 times lower then under realization of thermal methods) and necessary final humidity of the waste (20 – 25% in case of utilization by a method of vibro-blowing dehydration). One of the most prospective types of equipment for mechanical separation of the damp dispersive waste are presses with hydraulic drive that have relatively compact dimensions, high energy efficiency and reliability and provide a possibility for wide-range and infinitely variable control of main parameters of a loading regime of the waste processing. There is a scheme of an improved and high effective installation with hydraulic drive for separation of damp dispersive materials is presented in the article. Besides there are elaborated equations of its mathematic model that connect working parameters of separation, design parameters of the installation and physical-mechanical characteristics of the processed material. These equations can be used for optimization of the installation’s design and for creation of its method of projecting calculation.

Authors: Tuskaeva Z.R.
Published: May 2022

Assessment of technical equipment and the level of mechanization of work are one of the most significant issues in terms of management of construction activities. To date, sufficiently objective and convenient methods of such an assessment have not yet been proposed. Therefore, it is necessary to develop and use them. The author of this article aims to develop a quantitative assessment of the technical equipment of construction organizations of different levels, including integrated ones. Applied, retrospective, statistical, abstract-logical and expert research methods. A system of local indicators for assessing technical equipment is proposed, which subsequently provides the ability to calculate the integral. Indicators for assessing the level of technical equipment can be used by various organizational structures in construction. The weights of particular indicators have been determined and formalized methods for their calculation have been developed. A technique for assessing the general level of technical equipment is proposed. The approaches proposed in the article should be considered as tools that allow an objective assessment of the level of technical equipment for organizational structures of different levels

Bootstrap Methods for Claims Reserving: R Language Approach
Authors: Zaçaj Oriana , Raço Endri , Haxhi Kleida , Llagami Etleva , Hila Kostaq
Published: May 2022

Bootstrap methods have been used by actuaries for a long time to predict future claims cash flows and their variability. This work aims to illustrate the use of bootstrap methods in practice, taking as an example the claims development data of the personal accident portfolio from the largest insurance company in Albania, over a period of 10 years. It is not the objective of this work to provide a theoretical analysis of the bootstrap methods, rather, this work focuses on highlighting the benefits of using bootstrap methods to predict the distribution of future claims development, and estimate the standard error, for a better risk assessment of liabilities within insurance companies. This work is divided into two well-differentiated phases: the first is to select the theoretical probability distribution that best fits the available claims dataset. Comparison of distributions is facilitated by the possibilities offered by the R programming languages. Both, the maximum likelihood parameter estimation method and the chi-square goddess goodness of fit test, are used to specify the probability distribution that best fits the data, among a family of predefined distributions. The results show that the Gamma distribution better describes the claim development data. The next phase is to use bootstrap methods, based on the selected distribution, to estimate the ultimate value of claims, the claims reserve, and their standard error.

Krise, Katastrophe, Krieg – sind wir richtig vorbereitet?
Authors: Kuhlmey Marcel
Published: May 2022

Die militärischen Auseinandersetzungen in der Ukraine sowie deren Auswirkungen auf die Bevölkerungen und auch die Europäische Union zeigen deutlichen Handlungsbedarf im Bereich des Bevölkerungsschutzes auf. Nach der Wiedervereinigung und dem Zusammenbruch des Warschauer Paktes schien eine Bedrohung der Bundesrepublik Deutschland durch einen Krieg nahezu ausgeschlossen. In der Folge wurde der Zivilschutz bedingt durch die damalige Bedrohungsanalyse auf ein Mindestmaß reduziert. Im Rahmen des Zivilschutzes greift der Staat auf die bereits etablierten Strukturen, Kräfte und Mittel des Brand- und Katastrophenschutzes zurück. Insofern stellt sich zum heutigen Zeitpunkt die Frage nach dem Vorbereitungsgrad des Staates und seiner Organisationen sowie der Wirtschaft auf derartige krisenhafte Ereignisse. Der Beitrag soll den Vorbereitungsstand näher betrachten.

Authors:   BAKU HIGHER OIL SCHOOL 30, Khojaly Ave., Baku, AZ1025, Azerbaijan, MUSAYEVA S.A.
Published: May 2022

One of the most important tasks of modern natural science is energy saving and replacement of non-renewable energy sources with wind, solar, geothermal, wave and other energies. The main advantage of geothermal water is that it can be supplied in places where it is continuously regenerated and directly consumes heat, energy, more importantly, useful chemistry, has healing properties and abilities. The article discusses the influence of the temperature factor on the value of hydrostatic pressure while drilling of geothermal wells using chemical reagents based on water-soluble polymers in the process of drilling deep wells, which ensure the stability of drilling fluids at high temperatures.As mentioned earlier, the regulation of hydrostatic pressure by increasing the drilling mud densityat high temperatures is inappropriate. Therefore, it is necessary to take measures to improve the sedimentation stability of drilling muds.

Is the Black-widow Pulsar PSR J1555–2908 in a Hierarchical Triple System?
Authors: Nieder L. , Kerr M. , Clark C. J. , Bruel P. , Cromartie H. T. , Ransom S. M. , Ray P. S.
Published: May 2022

The 559 Hz black-widow pulsar PSR J1555−2908, originally discovered in radio, is also a bright gamma-ray pulsar. Timing its pulsations using 12 yr of Fermi-Large Area Telescope gamma-ray data reveals long-term variations in its spin frequency that are much larger than is observed from other millisecond pulsars. While this variability in the pulsar rotation rate could be intrinsic “timing noise,” here we consider an alternative explanation: the variations arise from the presence of a very-low-mass third object in a wide multiyear orbit around the neutron star and its low-mass companion. With current data, this hierarchical-triple-system model describes the pulsar’s rotation slightly more accurately than the best-fitting timing noise model. Future observations will show if this alternative explanation is correct.
Formes de vie et dynamique historique chez Max Horkheimer
Authors: Carbone Raffaele
Published: May 2022

Résumé Cet article explore les significations de l’expression « formes de vie » chez Horkheimer et le rôle qu’elle joue dans son projet d’une Théorie critique de la société développée au cours des années 1930. Horkheimer considère les formes de vie comme des comportements et des habitudes qui se constituent dans le cadre de rapports de production spécifiques. Mais il utilise « forme de vie » également pour désigner la culture et ses domaines propres qui, imbriqués les uns dans les autres, sont des forces capables de maintenir ou de briser une forme sociale déterminée. En outre, par « forme de vie », il entend le résultat des relations entre les processus matériels d’une société et le développement des phénomènes culturels qui influencent les institutions et les hommes.
Difformer la vie
Authors: Ferrarese Estelle
Published: May 2022

Résumé De multiples théories contemporaines font de la politique une affaire de création d’une nouvelle forme de vie ; il est postulé que c’est en vivant (autrement) que l’on transforme le monde. Deux logiques se distinguent : une politique de la discipline, et une politique de l’exubérance ou de l’informe. Cet article s’en détache pour dégager de la pensée d’Adorno les éléments d’une politique du difforme  : il confère à la forme (et non à la vie) le rôle de maintenir une indétermination, pensant une forme qui n’oublie pas qu’elle est forme, qu’elle est issue d’un mouvement qui aurait pu être autre.
« Ici, c’est l’Afrique ». Fonctionnaires métropolitain·es à Mayotte et construction de la blanchité dans l’État postcolonial
Authors: Girard Violaine , Féliu François , Noûs Camille
Published: May 2022

Que signifie incarner l’État à Mayotte lorsque l’on est natif·ve de l’ancienne métropole coloniale et catégorisé·e comme blanc·he ? Et comment se positionnent les fonctionnaires métropolitain·es en poste dans ce territoire demeuré sous la souveraineté française lors des décolonisations du xx e siècle et devenu département d’outre-mer en 2011 ? Pour présenter les parcours d’agent·es muté·es depuis l’Hexagone, nous mobilisons la notion de blanchité, et montrons que les avantages structurels dont ils et elles bénéficient dans la poursuite de leurs carrières s’articulent à des privilèges symboliques fondés sur la race. Alors que la hiérarchie administrative est marquée par une forte ségrégation verticale, la posture faite d’extériorité vertueuse des agent·es métropolitain·es vient renforcer leurs positions dominantes au sein des services de l’État, tandis que diverses formes de disqualification contribuent parallèlement à l’exclusion des Mahorais·es, natif·ves de l’île, des postes les plus qualifiés. La blanchité constitue ici une propriété sociale discriminante, au sein d’un État postcolonial pourtant réputé aveugle à la race.
Volontaires au service de l’État en Guadeloupe : la construction paradoxale de la blanchité des jeunes Français·es de l’Hexagone
Authors: Ihaddadene Florence
Published: May 2022

Successeur du dispositif de Volontariat à l’aide technique, le Volontariat de service civique (VSC) encourage l’investissement de jeunes diplômé·es dans des missions hors du droit du travail au sein des administrations déconcentrées de l’État français dans les départements ultramarins. Précaires, au sens où ils et elles ne sont pas stabilisé·es dans l’emploi avant leur départ, la majorité de ces volontaires sont originaires de la France hexagonale. Une enquête à partir d’entretiens réalisés en Guadeloupe permet de penser l’usage de ce programme par les administrations, qui cherchent à faciliter la mise en place de politiques publiques sans faire appel à des fonctionnaires titulaires et contractuel·les. De fait, par une procédure floue et discriminante, le VSC participe à l’exclusion des Guadeloupéen·nes, tout en confiant à de jeunes Hexagonaux·les la prise en charge des enjeux environnementaux de l’île. À partir de cette situation inégalitaire, au fondement de l’« exceptionnalité ultramarine », ces « quasi-expat » découvrent et construisent leur blanchité, tant dans les hiérarchies professionnelles que dans leur mode de vie, contribuant à la fois à la reproduction de l’État français en outre-mer et à leur propre insertion professionnelle.
Guerre civile et régimes identitaires : l’ethnicisation du conflit en Équatoria-Occidental (Soudan du Sud)
Authors: Veuillet Emmanuelle
Published: May 2022

Dès le début de la guerre civile au Soudan du Sud, une logique d’ethnicisation a été mise en place qui a abouti à une polarisation identitaire, notamment dans la région d’Équatoria-Occidental. De nouveaux régimes identitaires portés aussi bien par le gouvernement que par les groupes d’opposition, mais sur la base de critères différents, ont ainsi bouleversé la vie et les pratiques quotidiennes des habitant·es de cette région. Ce sont la configuration inédite de ces régimes identitaires et leur interaction qui définissent les dynamiques d’ethnicisation visibles dans les pratiques de contrôle et de surveillance, ainsi que dans les épisodes de violence, mais aussi dans les comportements individuels et collectifs qu’elles génèrent. Il convient donc de rendre compte, d’une part, de ces régimes identitaires, à travers les catégorisations utilisées et les logiques de hiérarchisation adoptées, d’autre part, des processus par lesquels l’ethnicité est devenue dans le conflit une affiliation politique et un critère de réorganisation de l’espace social et politique.

Les tests de connaissance sont alors rapidement apparus comme un moyen d’obtenir des évaluations objectives préservant l’égalité entre les apprenants ou les candidats. Cette nécessité est ressentie par les institutions d’enseignement supérieur en gestion qui doivent mettre en place des dispositifs d’assurance qualité, notamment pour accéder aux accréditations internationales. Nous présentons ici un test de connaissances fondamentales en gestion, G-Skor, qui constitue un instrument externe de nature à répondre à ce besoin en fournissant des mesures individuelles et collectives de la performance d’apprentissage. Le processus de son élaboration contribue positivement à sa fidélité et sa validité de manière à minimiser le risque d’erreur de mesure inhérent à tout procédé d’évaluation d’un construit à partir d’items et, par voie de conséquence, le risque d’émettre un jugement erroné sur le niveau réel d’un sujet.
Management stratégique des risques des entreprises chinoises : une analyse IBV-VUCA sur la « nouvelle route de la soie »
Authors: Gao Huiyi , David Patricia
Published: May 2022

L’Initiative de « la Ceinture et la Route » (ICR) du gouvernement chinois accélère les investissements de ses entreprises à l’étranger. Si l’ICR correspond à la première phase de la matérialisation économico-idéologique de la stratégie globale de l’État chinois, avec l’émergence de la Route de la Soie numérique («  Digital Silk Road  ») débute une seconde phase de la dématérialisation de l’ICR avec des répercussions économico-politiques et socioculturelles sur l’économie mondiale. Dans ce contexte, les parties prenantes du projet ICR sont confrontées aux nouveaux défis caractérisant la société du risque global, selon les quatre axes VUCA ( Volatility, Uncertainty, Complexity, Ambiguity ). Cet article cherche à identifier la capacité de transformation de ces nouveaux risques en opportunités de développement des entreprises. Les résultats de l’étude de cas de China Telecom montre le nouveau contexte dans lequel l’entreprise élabore ses stratégies et réagit de façon proactive à ses environnements concurrentiels.
Les nouvelles défenses de la propriété privée et leurs limites : libertarisme et droit naturel après Nozick
Authors: Fabri Éric
Published: May 2022

Résumé La propriété privée est-elle un droit naturel ? Cette thèse défendue entre autres par les libertariens de droite dans le dernier quart du 20e siècle a connu un récent regain d’intérêt. Au cours des années 2010, Eric Mack, Billy Christmas et Bas van der Vossen ont cherché à restaurer la crédibilité de la théorie des habilitations de Robert Nozick en répondant à ses critiques. Ce-faisant, ils ont développé de nouveaux arguments pour conférer à la propriété privée un statut de droit naturel capable de justifier les inégalités économiques et de limiter les interférences redistributives de l’État. Après avoir clarifié la manière dont la théorie des habilitations de Robert Nozick mobilise la normativité supérieure associée à la théorie des droits naturels pour défendre l’État minimal, cet article examine trois des principales objections qui ont été adressées à cette théorie, ainsi surtout que les réponses à ces objections développées depuis 2010 respectivement par Eric Mack, Billy Christmas et Bas van der Vossen. Il conclut qu’aucun de ces nouveaux arguments ne réussit à sauvegarder le statut de droit naturel de la propriété privée.
Une appropriation du développement durable par la bande dessinée
Authors: Cez Prisca
Published: May 2022

Le 9 e art est un médium qui possède une histoire qui s’écrit encore aujourd’hui. Après avoir été considéré comme un simple outil de divertissement pour les enfants, il devient progressivement une lecture pour les adultes. Le genre s’affirme pour passer d’une existence réservée à la presse pour prendre son indépendance en album. La prise de conscience écologique concerne une partie du monde de la bd , dont des scénaristes, des dessinateurs ou des journalistes, qui s’en emparent pour dénoncer, critiquer, se moquer des choix de société des élites et des politiques. Au fur et à mesure, le développement durable devient un vrai sujet de fond qui prend sa place dans le panel des publications.
Global well-posedness of the Cauchy problem for the Jordan–Moore–Gibson–Thompson equation with arbitrarily large higher-order Sobolev norms
Authors: Said-Houari Belkacem
Published: May 2022

In this paper, we consider the 3D Jordan–Moore–Gibson–Thompson equation arising in nonlinear acoustics. First, we prove that the solution exists globally in time provided that the lower order Sobolev norms of the initial data are small, while the higher-order norms can be arbitrarily large. This improves some available results in the literature. Second, we prove a new decay estimate for the linearized model removing the \begin{document}$ L^1 $\end{document}-assumption on the initial data. The proof of this decay estimate is based on the high-frequency and low-frequency decomposition of the solution together with an interpolation inequality related to Sobolev spaces with negative order.
Coulombic efficiency estimation technique for eco-routing in electric vehicles
Authors: Das Kritanjali , Sharma Santanu
Published: May 2022

A battery source is an indispensable component in electric vehicles and its efficient usage results in improvement of battery life. The amount of energy stored in batteries, including their state of charge and efficiency, are critical metrics for evaluating vehicle performance. This article presents an automated motor-generator linked technique for estimating battery-related parameters, which is an essential aspect of eco-routing in electric vehicles. This system enables discharging of a battery at various current rates by constant resistive loads which are electronically applied. The charging process however uses a charger attached to various sensors for estimating the current. The coulomb counting method has been used which provides information of State of Charge and Coulombic Efficiency of the test battery. Since battery behavior is dynamic; the energy source was charged and discharged over numerous cycles at various current rates. The experimental set-up uses sensors for accurate data acquisition. In addition to the experimental set-up, an electrical circuit battery model has also been simulated in this work. All simulation as well as post processing tasks have been done in the Arduino-MATLAB environment. The main highlight of this system is that the system is portable, easy to operate, low cost and can be used to test all types of batteries. The proposed system is simple and has yielded good results. The battery parameters obtained prove to be vital for range determination in eco-routing of electric vehicles among other applications.
Number of maximal 2-component independent sets in forests
Authors: Cheng Shuting , Wu Baoyindureng
Published: May 2022

Let $ G = (V(G), E(G)) $ be a graph. For a positive integer $ k $, we call $ S\subseteq V(G) $ a $ k $-component independent set of $ G $ if each component of $ G[S] $ has order at most $ k $. Moreover, $ S $ is maximal if there does not exist a $ k $-component independent set $ S' $ of $ G $ such that $ S\subseteq S' $ and $ |S| < |S'| $. A maximal $ k $-component independent set of a graph $ G $ is denoted briefly by Mk-CIS. We use $ t_k(G) $ to denote the number of Mk-CISs of a graph $ G $. In this paper, we show that for a forest $ G $ of order $ n $,

   \begin{document}$ t_2(G)\leq \left\{ \begin{array}{ll} 3^{\frac{n} 3 },& \text{if}\quad { n\equiv 0\ (mod\ 3) \; \text{and} \; n\geq3 },\\ 4 \cdot 3^{\frac{n-4} 3 },& \text{if}\quad { n \equiv 1\ (mod\ 3) \; \text{and} \; n\geq 4 },\\ 5,& \text{if}\quad { n = 5 },\\ 4^{2} \cdot 3^{\frac{n-8} 3 },& \text{if}\quad { n\equiv 2\ (mod\ 3) \; \text{and} \; n\geq 8 }, \end{array} \right. $\end{document}

with equality if and only if $ G\cong F_n $, where

   \begin{document}$ F_n \cong \left\{ \begin{array}{ll} \frac n 3 P_{3},& \text{if}\quad { n\equiv 0\ ( mod\ 3) \; \text{and} \; n\geq 3 },\\ \frac {n-4} 3 P_{3}\cup K_{1,3} ,& \text{if}\quad { n \equiv 1\ ( mod\ 3) \; \text{and} \; n\geq 4 },\\ K_{1,4} ,& \text{if}\quad { n = 5 },\\ \frac {n-8} 3 P_{3}\cup 2K_{1,3},& \text{if}\quad { n\equiv 2\ ( mod\ 3) \; \text{and} \; n\geq 8 }. \end{array} \right. $\end{document}

Objectives: Infections with hepatitis B, C, and D virus (HBV, HCV, and HDV) are a major public health problem and lead to serious complications such as cirrhosis and hepatocellular carcinoma. We aimed to determine the seroprevalence of hepatitis B surface antigen (HBsAg), anti-HCV, anti-HDV immunoglobulin G, alpha-fetoprotein (AFP), and dual and triple hepatitis virus infections in Mongolia.Methods: A total of 2313 participants from urban and rural regions were randomly recruited for this cross-sectional study. A questionnaire was used to identify the risk factors for hepatitis virus infections, and the seromarkers were measured using immunoassay kits.Results: Among all participants, the prevalence of HBV, HCV, and HDV was 15.6%, 36.6%, and 14.3%, respectively. The infection rates were significantly higher in females and participants with a lower education level, rural residence, older age, and a history of blood transfusion. HBV and HCV co-infection was found in 120 (5.2%) participants and HBV, HCV, and HDV triple infection was detected in 67 (2.9%) participants. The prevalence of elevated AFP was 2.7%, 5.5%, and 2.6% higher in participants who were seropositive for HBsAg (p=0.01), anti-HCV (p<0.001), and anti-HDV (p=0.022), respectively. Elevated AFP was more prevalent in participants co-infected with HBV and HCV (5.8%, p=0.023), HBV and HDV (6.0%, p<0.001), and triple-infected with HBV, HCV, and HDV (7.5%) than in uninfected individuals.Conclusions: Nearly half (49.8%) of the study population aged ≥40 years were infected with HBV, HCV, or HDV, and 22.4% had dual or triple infections.
