Authors:   Ivanovo State Power Engineering University, Bushuev E.N. , Zholobova A.Yu. ,   Ivanovo State Power Engineering University
Published: September 2024

There are many viable options of desalination schemes that allow us to obtain purified water of the required quality. To conduct process design of a water treatment plant, thermal power plants and nuclear power plants use special software provided by manufacturers of ion exchangers and membrane elements. However, these software programs consider individual water treatment technologies and are attached to filter and membrane materials of a specific manufacturer. They do not provide the ability to calculate complete water desalination schemes, as well as determine the performance indicators of the water treatment plant. It is relevant to develop a software program that allows us to conduct process design of complete water treatment schemes, which include various water treatment technologies, and to determine technological, environmental, and technical-economic indicators. Multivariate calculations with different initial data will allow us to identify the advantages and disadvantages of scheme solutions and determine areas of their rational use. The method of mathematical modeling of chemical and technological processes of water treatment at thermal power plants and nuclear power plants has been used. An application software program “PROJECT WTP” has been developed. It is designed for process design of various water treatment schemes, which are visually assembled from individual elements, and allows one to determine the technological, environmental, and performance indicators of the operation of water treatment plant. Computation data on the auxiliary need coefficient has been obtained for the main water desalination schemes and under condition of different mineralization of the source water. The developed software program can be used for process design of various water treatment schemes and assessment of the degree of improvement of water desalination technology.

Authors:   Samara State Technical University, Bannov D.M. , Polishchuk V.I. ,   Polzunov Altai State Technical University
Published: September 2024

The study is relevant due to high requirements to the reliability of the operation of auxiliary mechanisms of thermal power plants (TPP). The main source of mechanical power of auxiliary mechanisms of TPPs is high-voltage induction motor with squirrel cage rotor (IMSC). One of the most difficult causes of emergency shutdown to detect early is a broken rotor bar. The breakage of IMSC rotor bar is of latent character. It can be for a long time without considerable influence on the machine operation mode. Nevertheless, the fact of the breakage can be considered as an emergency condition of IMSC, and the consequences of leaving the groove of the magnetic core are irreversible. Scientifically, early diagnostics of IMSC rotor bars breakage of TPP auxiliary needs is both a difficult and extremely urgent task. The existing methods of diagnostics of such damage are based on measurement and analysis of vibration and acoustic physical quantities. The most common electrical parameter, used as a source of information, as a rule, is current consumption. And most of methods are based on Fourier analysis. The purpose of the study is to develop a mathematical algorithm to process digitized curves of stator phase currents to diagnose high-voltage IMSC. The theory of electric machines, the method of analytical approximation of experimental data, the method of regression analysis have been used to solve the problem. Experimental data is obtained, and testing of the algorithm is conducted on an experimental installation with a 0,4 kV induction motor with a modified design of the active part of the rotor developed for physical simulation of IMSC broken rotor bar. This paper proposes a new method of digital processing of stator current signals based on the regression analysis method for diagnostics of IMSC rotor winding. The authors have developed an algorithm for mathematical processing of digitized stator current curves based on regression analysis in the cosine-sine basis to identify the diagnostic sign of failure of one rotor bar of IMSC rotor. The authors have determined the number of harmonic components that best describe the initial signal from the point of view of the balance between saving computational resources and accuracy of approximation. A mathematical algorithm to detect the rotor bar breakage of an induction motor based on regression analysis of stator currents has been obtained and tested. It allows to detect rotor circuit damage with 97 % accuracy. At the same time the diagnostic sign changes its level when one bar breaks by 5 %. It is recommended to adapt the algorithm to the programming languages of microprocessor relay protection units.
Specificity of the Study of Gameplay in Video Games and Its Link with Aggression in International Studies
Authors: Ponomareva E.S.
Published: September 2024

The article addresses the problem of designing a research model applicable to study of enthusiasm for video games and aggression. As a possible way to overcome the existing contradictions in the research results, it is important to study this interplay, taking into account the features of play activity. Video game is not an accurate model of reality. It is based on a different, significantly simplified system of rules, and has a conventional nature. Thus, it seems important to go on collecting information concerning the psychological aspects of the game process, especially the ones, connected with the reflection of the play experience and the features of behavior in the game. The purpose of this review is to identify the specificity of designing studies aimed at investigating the problem of the implementation of the game process in video games and aggression in relation to the specificity of play activity. In few publications that pay attention to the psychological components of the gameplay its individual aspects (perception of frustrating game events, realism of the game space and involvement in the game context) are often discussed without taking into account the specificity of the game. In perspective we intend to particularize the specificity of processing the play experience, namely, the way it reflects in the chosen game tactics.
Rapid Fatality Estimates after Earthquakes in Western Mediterranean Countries for First Response
Authors: Wyss Max , Rosset Philippe
Published: September 2024

The quality and speed of the current earthquake fatality estimates in Italy, Greece, Spain, Morocco, and Algeria by Quake Loss Assessment for Response and Mitigation (QLARM) is analyzed. The positive conclusion is that all investigated major earthquake disasters have been recognized as red alerts. In all but one of the tests, the range of estimated fatalities bracketed the number of finally reported fatalities. In five out of nine test earthquakes, the range of likely fatalities was calculated in real time, that is, within minutes after the respective earthquakes. These earthquakes occurred during the last 20 yr and only the minimal information of point sources was available. Additional four tests were performed for fatal earthquakes that occurred in the twentieth century and for which magnitudes and extents of the ruptures are known. The negative conclusions are: (1) locations and properties of critical facilities, such as hospitals and schools are still not made available by some governments, although in the case of earthquake disasters, first responders should be informed about their conditions. (2) News media and governments still do not pay attention to the quantitative estimates of fatalities 26 min (median) after earthquakes by QLARM and instead disseminate underestimates by up to two orders of magnitude for days and weeks. (3) The directions and extents of ruptures remain unknown for days and weeks, leading to poor information on the spatial distribution of victims at first. (4) Source locations by different worldwide and local agencies differ by several to 20 km, which can lead to misestimates of fatalities up to 20,000. If rapid earthquake locations of quality were available in earthquake prone areas, such errors could be avoided, and the time to estimate numbers of fatalities could be reduced by an order of magnitude.

Published: September 2024

Nowadays, one of the most crucial challenges for higher education teachers is to improve student motivation and engagement. Educational gamification, i.e., the addition of game techniques and models in non-game contexts arises as a support to avoid students’ distraction and get interested in the course content. Digital badges are a gamification tool that has witnessed a growing application in recent times. Digital badges are tokens employed to officially record or validate achievements in the realm of academia or any other domain. In this paper, we analyze the impact of the use of digital badges, as a strategy of educational gamification. We conduct a study involving 150 higher education students, specifically in the subject of database workshop, to whom the digital badges have been applied as a part of the system to accredit learning. The obtained results were analyzed through objective and subjective measurements indicating that the application of digital badges seemed to have a positive impact on student learning.

The Impact of Out-of-field STEM High School Teachers on College Decisions: Evidence from Chile
Authors: Aburto Mauricio Hernán , Elacqua Gregory , Kutscher Macarena
Published: September 2024

This paper examines the effects of out-of-field teachers during secondary education on students, focusing on academic performance and college choices in STEM subjects, using detailed data from Chile. Our findings indicate a generally negative impact of out-of-field teaching in Math, Chemistry, and Physics on the likelihood of students taking the college entrance exam, while Biology's impact appears negligible, possibly due to its less intensive use of mathematics. Specifically, out-of-field teaching in these subjects decreases student's participation in the science portion of the college entrance exam, critical for STEM program admissions. Although students interest in STEM majors is not broadly affected, those taught by out-of-field Physics teachers show a reduced preference for STEM fields. The study also highlights that out-of-field teaching lowers college enrollment rates, especially in STEM majors, with low-socioeconomic status students and males being particularly affected. Males have lower rates of exam participation and suffer more from out-of-field teaching in Physics and Chemistry, while females face obstacles enrolling in STEM programs after being taught by out-of-field teachers in Physics.

Authors: Luzes Marta , Rivera Rivera Alejandra , Rodríguez Guillén Lucina , van der Werf Cynthia
Published: September 2024

This paper examines the impacts of a migrant regularization program implemented in Peru in 2021. We find that the regularization process positively impacted migrant integration through labor outcomes (access to a written contract and increased income), social outcomes, and access to health services. The results of this study provide evidence of the importance of regularization programs for migrant populations and their impacts on well-being and productive integration in a context of high employment informality and limited public service coverage. The lessons learned are essential not only for developing countries where unexpected migratory flows have made regularization processes common but also for similar south-south movements, where the presence of migrants can pose unique challenges for host societies.

Published: September 2024

Digital payment solutions have recently gained extraordinary popularity across the globe. Many individuals in cities or urban areas have begun to use these payment systems for financial transactions. The combined use of different advanced technologies is indispensable for widespread adoption. Various obstacles to performing financial transactions using digital payment systems must be considered. Among these obstacles, security is the most remarkable point. Although this online payment system is fast and convenient, the chances of fraud are very high. A cybercriminal can hack into the system, stealing personal information like phone numbers and passwords. This article will focus on a new digital payment security system that will take advantage of artificial intelligence (AI), big data, and biometric authentication (BA). When using this security system, a transaction request will be sent. First, it will check whether the phone number is a registered user and if it is, further authentication will be carried out. The system will automatically authenticate the user’s identity with the help of facial recognition technology that will analyze the features of the face. Further, the user has to show various gestures that are analyzed by the system. This and other personal information will be converted into a number and then encrypted before being stored in the database. The incoming transaction request will be compared against the personal number. If the user is not unique, the transaction request will be immediately rejected. Secondly, if the number matches but the user is fraudulent, the transaction will also be rejected. Only if both are unique, the system will check for duplicate numbers among the other transactions for the particular period. If other numbers are not found, the transaction is executed; otherwise, it is still rejected. This is done to find out fake and auto-generated numbers. This security system will be helpful to ensure the authenticity of the user in digital payment systems.

Published: September 2024

V našem podjetju smo se soočali z izzivi pri avtorizaciji poslovne logike, kar je vplivalo na učinkovitost in varnost naših storitev. Da bi izboljšali ta proces, smo raziskali različne pristope in orodja za avtorizacijo ter se osredotočili na enostavnost in hitrost vpeljave. Odločili smo se za rešitev z uporabo Open Policy Agent (OPA), ki jo bomo predstavili v članku. OPA je odprtokodno orodje za enotno politiko avtorizacije, ki omogoča centralizirano izvajanje politik. Politike dostopa v OPA so napisane v jeziku Rego, kar omogoča fleksibilno pisanje pravil za avtorizacijo. Predstavili bomo tudi OPAL (OPA Policy Administration Layer), ki omogoča dinamično posodabljanje politik dostopa brez prekinitev delovanja storitev. OPA v naši infrastrukturi deluje kot Policy Decision Point (PDP), odgovoren za sprejemanje odločitev glede avtorizacije. Uporabljamo decentraliziran pristop, kjer je PDP implementiran kot "sidecar" ob posameznih storitvah, kar zagotavlja hitrejše odzivne čase in boljšo porazdelitev obremenitve. V članku bomo predstavili tudi spremembe in izzive pri razvoju sistema, saj je ločeno pisanje avtorizacijskih politik sprva povzročalo nekaj preglavic, predvsem v obliki pozabljenih politik dostopa in zavrnjenih zahtevkov.

V prispevku predstavljamo, kakšne prednosti prinaša upodabljanje spletnih aplikacij na strežniku (ang. Server-Side Rendering, v nadaljevanju SSR) v nasprotju s prikazovanjem pri odjemalcu (ang. Client-Side Rendering, v nadaljevanju CSR). SSR je tehnika spletnega razvoja, pri kateri strežnik ustvari celotne strani, prilagojene za vsako zahtevo uporabnika, in jih dostavi brskalniku uporabnika. Ta pristop ponuja mnogo prednosti, vključno s hitrejšim začetnim nalaganjem strani, izboljšano optimizacijo za iskalnike in boljšo zmogljivostjo na napravah z manjšo procesorsko močjo. V uvodu bomo izpostavili, s kakšnimi težavami se srečujemo kot razvijalci spletnih aplikacij s prikazovanjem pri odjemalcu in kako bi se jih lahko lotili z uporabo spletnih aplikacij na strežniku. Podrobneje bomo predstavili, kaj je SSR, in pregledali ogrodja, ki jih lahko uporabimo za generiranje vsebine spletnih aplikacij na strežnikih, kot sta Remix in Next.js. Na praktičnem primeru bomo prikazali rezultate posameznih metrik, ki so relevantne pri prikazovanju, nalaganju in delovanju spletne aplikacije. Prispevek zaključimo z razmišljanjem o časovnih, prostorskih in omrežnih obremenitvah, ki jih prinese razvijanje dotičnih spletnih aplikacij.

Published: September 2024

CI/CD cevovodi postajajo nepogrešljivo orodje pri razvoju informacijskih sistemov, vendar je njihov življenjski cikel razmeroma slabo raziskan. V članku na podlagi pregleda literature opredelimo CI/CD cevovode, njihovo pogostost, najpogostejše gradnike ter orodja za vzpostavitev CI/CD cevovodov. Predstavimo tudi empirično raziskavo, ki vključuje podrobno analizo 1000 repozitorijev na platformi GitHub. Da bi raziskali življenjski cikel CI/CD cevovodov smo preučili strukturo cevovodov v repozitorijih in spremembe tekom projekta. Ugotovili smo, da so CI/CD cevovodi prisotni v 42% repozitorijev, povprečen čas do njihove vključitve pa je sedem mesecev. Skoraj vsi analizirani cevovodi vključujejo gradnjo, 62% jih vključuje tudi izdajo, 46% testiranje, 26% analizo kode in zgolj 18% namestitev. Analizirali smo tudi spremembe programske kode in cevovodov tekom projekta, ter ugotovili, da se ob povečanju sprememb v kodi poveča tudi število sprememb cevovodov in da spremembe cevovodov v povprečju predstavljajo 4% vseh sprememb v repozitoriju. Ugotovili smo tudi, da se cevovodi najbolj spreminjajo na začetku in koncu razvoja projektov, kar odraža njihovo vzpostavitev in kasnejše prilagoditve ter optimizacije.

Published: September 2024

Pojav frontend razvojnih ogrodij je še povečal vrzel med frontend in backend razvojem. V podjetju smo želeli razširiti funkcionalnosti interne spletne aplikacije in s tem zagotoviti večjo učinkovitost ekip, vendar nismo imeli prostih frontend razvijalcev. Zato smo se odločili raziskati alternativne pristope, ki bi omogočil razvoj frontend in backend aplikacij v enakem jeziku in okolju. Primerno rešitev ponuja razvoj aplikacij z .NET 8 Blazor in MudBlazor, kar bomo predstavili v članku. Z .NET 8 Blazor lahko razvijemo robustne in interaktivne spletne aplikacije v C#, brez potrebe po učenju dodatnega jezika. To poenostavi in pohitri razvoj, saj se razvijalci lahko osredotočijo na logiko in funkcionalnost aplikacije. Še večjo poenostavitev predstavlja uporaba knjižnice MudBlazor, ki temelji na Material UI in je zasnovana za Blazor. Ponuja izdelane in prilagodljive komponente, kar omogoča hitro izdelavo uporabniških vmesnikov. Tako smo izkoristili prednosti .NET razvoja in omogočili backend razvijalcem enostaven pristop k razvoju spletnih rešitev. V članku bomo predstavili Blazor in MudBlazor, razvojno strukturo, izzive in rezultate. Rešitev predstavlja spletna aplikacija, ki po strukturi spominja na backend projekte in omogoča hiter razvoj internih aplikacij, in s tem opolnomoči backend razvijalce. Dodali smo tudi peskovnik za preizkušanje konceptov uporabniške izkušnje brez dodatnega dela za frontend razvijalce.
Optimiranje delovanja zbirke podatkov časovne vrste
Authors: Mernik Igor , Klauzner Franc
Published: September 2024

Podatkovna zbirka je eden izmed kamenčkov v mozaiku celotne rešitve obračuna omrežnine, ki smo jo uvedli z rešitvijo podatkovne zbirke časovnih vrst. Ko smo začeli s projektom, smo pričakovali, da bo delo z velikimi količinami podatkov zahtevalo več dela kot je običajno z operativno-transakcijskimi podatkovnimi zbirkami. Predvidevali smo, da sistem ne bo dovolj odziven vsakič, ko bomo v aplikaciji napisali poljuben SQL stavek in ga izvedli. Ugotovili smo, da je delo z velikimi količinami podatkov dokaj drugačno. Da je delovanje podatkovne zbirke optimalno, je potrebno ustrezno nasloviti vsak delček procesa. Za vsak napisan SQL in vsak proces je potrebno razumeti, kako se bo odrazil na odzivnosti podatkovne zbirke. Ker se posamezne operacije izvajajo nekaj milijon-krat, vsak drobec neoptimalne izvedbe lahko pripelje do večurnega podaljšanja obdelav ali pa celo do nikoli končanih obdelav, če so le-te napisane tako, da zavzamejo preveč računalniških virov. V članku opisujemo, katere programske rešitve smo uporabili pri optimiranju podatkovne zbirke časovnih vrst in zakaj smo se odločili za takšno rešitev. V jedru članka je opisan postopek optimizacij podatkovne zbirke, najprej na ravni arhitekture rešitve, nato kako smo prilagodili aplikacijsko okolje in nastavitve na ravni podatkovne zbirke same ter uvedba nadzora nad optimalnim delovanjem podatkovne zbirke.

Background: The stunting prevalence in Central Java Province remains high. Six key messages, i.e. iron tablet supplementation, healthy latrines, exclusive breastfeeding, Integrated Health Care Post (Posyandu) visit, hand washing, and Antenatal Care visit are the efforts to reduce the prevalence of stunting.
Objectives: This study aimed to analyse the relationship between the behaviour of the six key messages and the stunting prevalence in four districts of Central Java Province.
Methods: This cross-sectional study was conducted in Brebes Regency, Tegal Regency, Banyumas Regency, and Semarang City with 424 mothers who have under two-year-old children randomly selected as sample. Data were collected by interview using a structured questionnaire with the results grouped into attitude and practices categories. The body’s weight and length were measured by a digital scale and infantometer. Data were analysed using the chi-square test.
Results: The findings indicated that 21.5% of children under two had stunting. Besides, behaviour regarding six key messages were mostly good. There was no association between mothers' iron tablet consumption behaviour and the nutritional status of under-two children. There was an association between maternal attitudes about exclusive breastfeeding and knowledge about hand washing with length for age index (p=0.004). There was also an association between antenatal care and Posyandu visits practice with weight for age index (p=0.004 and 0.018). There was a relationship between attitude regarding the use of latrines and the weight for length index (p=0.001).
Conclusions: Only the key messages of exclusive breastfeeding attitude, antenatal care visit practice, Posyandu visit practice, and hand washing attitude were associated with the nutritional status of under-two children.

Treating Anxiety-Based Cognitive Distortions Pertaining to Somatic Perception for Better Chronic Pain Outcomes
Authors: Silva Marcelina Jasmine
Published: September 2024

Anxiety-based cognitive distortions pertaining to somatic perception (ABCD-SP) - primarily catastrophizing, fear avoidance and kinesiophobia- have been repeatedly linked to worsening chronic, non-cancer pain (CNCP) outcomes of increased disability, amplified pain, ineffective opioid use, and opioid misuse. Several studies have suggested that treating ABCD-SP can improve pain outcomes. Utilizing a narrative review of proposed mechanisms, published patient perspectives, and study correlates connecting these cognitive distortions with CNCP outcomes, a better practice approach to the delivery of standard clinical CNCP care can be deduced. These recommendations require relatively few resources to implement and have the potential to lead to more effective CNCP treatment on a large scale.

Ransomware, a combination of "ransom" and "malware," is a type of malicious software designed to encrypt or block access to a victim's data or system, demanding a ransom for its release Initially targeting individuals, ransomware has evolved to attack businesses for greater financial gain. It mainly exists in two forms: encrypting ransomware, which holds data hostage, and non-encrypting ransomware, which blocks system access and displays a ransom note. The energy sector has been notably targeted by ransomware, exemplified by the 2021 attack on Colonial Pipeline by the DarkSide group, which led to a temporary shutdown and a significant fuel shortage on the US East Coast. Similarly, in 2023, Russian hackers using LockBit ransomware disrupted Royal Mail, halting international deliveries and incurring millions in recovery costs despite no ransom payment. These incidents underscore the need for comprehensive cybersecurity strategies that combine human vigilance with advanced technologies like AI and machine learning. By adopting a multi-layered protection approach, organizations can better prepare for and mitigate the risks posed by ransomware attacks safeguarding sensitive data and ensuring business continuity.

Published: September 2024

Clarifying the distribution of temperature and pressure in the wellbore and cavern during hydrogen injection and extraction is crucial for quantitatively assessing cavern stability and wellbore integrity. This paper establishes an integrated flow and heat transfer model for the cavern and wellbore during hydrogen injection and production, analyzing the variations in temperature and pressure in both the wellbore and the cavern. The specific conclusions are as follows. (1) The temperature and pressure parameters of hydrogen and natural gas within the chamber and wellbore were compared. Under identical injection and production conditions, the temperature of hydrogen in the chamber was 10°C higher than that of natural gas, and 16°C higher in the wellbore. The pressure of hydrogen in the chamber was 2.9 MPa greater than that of natural gas, and 2.6 MPa higher in the wellbore. (2) A comparative analysis was conducted on the impact of surrounding rock’s horizontal and numerical distance on temperature during hydrogen and natural gas injection processes. As the distance from the cavity increases, from 5 to 15 meters, the temperature fluctuation in the surrounding rock diminishes progressively, with the temperature effect in the hydrogen storage chamber extending at least 10 meters. (3) The influence of rock thermal conductivity parameters on temperature during the processes of hydrogen injection and natural gas extraction is compared. The better the thermal conductivity, the deeper the thermal effects penetrate the rock layers, with the specific heat capacity having the most significant impact.

Published: September 2024

CPPU (Forchlorfenuron (1-(2-chloropyridin-4-yl)-3-phenylurea), a synthetic cytokinin, is extensively used to enhance fruit size and quality size in several crops, including kiwifruit. This study examines the effects of three different CPPU application strategies on two different crop loads on the main fruit quality parameters. Our results show that a two application of CPPU significantly increased fruit weight, especially under standard crop load conditions, due to better resource allocation. Fruit firmness improved with 2 and 3-times CPPU applications, likely due to enhanced cell wall development, and was consistently affected by crop load, with higher loads resulting in softer fruits. CPPU applied twice did not significantly influence soluble solids content. This parameter was instead significantly influenced by the crop load, with standard load fruit showing higher sugar accumulation. Fruit dry weight showed similar trends, with CPPU having a more pronounced effect under standard crop loads. Overall, CPPU proved to be a cost-effective strategy to enhance fruit quality, particularly in orchards with standard crop loads, by balancing yield and sugar content.

The sleeping and grazing behaviors of horses play a crucial role in their health and welfare. In the horse industry, with the prevalent trend of individual single-stall farming in stable, accurately identifying various behaviors of horses within stables is imperative. This study has established a spatio-temporal dataset for horse postures and behaviors, proposed an algorithm utilizing a SE-SlowFast network with an enhanced loss function. This algorithm achieves automatic recognition of multiple postures and behaviors of horse simultaneously. The model developed in this study demonstrates high accuracy in identifying three postures within the stable: Standing, Crouching, and Lying, achieving respective accuracies of 92.73%, 91.87%, and 92.58%. Additionally, it accurately recognizes two behaviors: Sleeping and Grazing, achieving best accuracies of 93.56% and 98.77%. The overall best accuracy of the model is 93.9%. Experiments on video recognition confirm that the suggested model recognizes horse video data accurately. This study marks the first time computer vision technology has been used in the horse farming industry, achieving non-intrusive recognition of multiple horse postures and behaviors. This study provides valuable data support for livestock managers to evaluate the health conditions of horses, enhances the welfare of horses in stables, and contributes to the advancement of modern horse husbandry practices.
Project Requirements for Wireline Method of HDD
Authors: Zhang Wei
Published: September 2024

This paper gives a brief insight of project requirements for “Wireline” method of Horizontal Directional Drilling (HDD). In any drilling project, it is extremely important to know the precise location of existing lines, know the precise location of the advancing drill bit and know the precise location of the newly installed line. The wireline method is mainly used to accurately steer during medium (Midi-HDD), and large (Maxi-HDD). Today, there are two methods of HDD wireline steering: magnetic and gyro. The magnetic steering tool uses a surface tracking system to verify the tool’s precise underground position. Sensors located within the down-hole provide constant updates of Inclination, Azimuth and Tool Face orientation to the surface via a wireline. The data is processed utilizing computers from the surface and specialized Steering software to provide information on depth, course length and distance off the predetermined azimuth. In addition to a great steering method, HDD projects require the presence of well-trained and experienced steering technicians. Those people are specifically trained to operate the machinery, and it would be counterproductive to work with such great equipment without the help of the correct operators. In conclusion, the wireline method of HDD has a unique capability to track the location of the cutterhead and steer it during the drilling process. The result is a greater capability in placing the necessary utilities in difficult underground conditions.

The samples from lunar farside have great significance for the study of the Moon, and even the solar system. Chang’e-6 landed successfully on the southern mare of the Apollo basin and returned ~2 kg samples from lunar farside. To provide a better understanding for the background of the returned samples, we conducted detailed crater size-frequency distribution (CSFD) measurements in the Chang’e-6 landing region, the southern mare of the Apollo basin. The southern mare is divided into western mare (W region) and eastern mare (E region), and then subdivided into five sub-units (W1, W2, W3, W4, W5) and three units (E1, E2, E3), respectively, according to the elevation, Ti and Fe abundances. Within the W2 and W5 region, more detailed sub-units were divided. The results show that the southern mare generally have two epochs, one of the Imbrian period and the other of the Eratothenian period. The basalt eruption lasted for ~1.7 Ga, from 3.28 Ga of the eastern mare to 1.54 Ga of the western mare. W region is younger than E region, while the three units of E region has an age of ~3.2 Ga. The ages of the western mare basalts range from 2.98 Ga to 1.54 Ga, lasting for 1.4 Ga. It’s worth noting that the age of the basalt at the Chang’e-6 sampling site is ~1.68 Ga, indicating the samples returned may include components with this very young age.
