Authors: Khudair Abbas Al-Khafaji Alaa , Bashar Talib Al-Nuaimi
Published: June 2024

The outbreak of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which causes coronavirus disease 2019 (COVID-19), has spread worldwide. Therefore, this study aimed to build a phylogenetic tree of complete genomes of SARS-CoV-2 and other species of Gamma coronavirus  to explore the possibility of finding the evolutionary relationships between them and wished to analyze them in order to forecast the best trees illustrating the sequences' evolutionary relationships and obtain a well-supported phylogenetic tree by using the Neighbor-Joining (NJ) and Maximum Likelihood (ML) methods after performing multiple sequence alignment (MSA). This study utilized 16 isolates of Gamma coronavirus species and SARS-CoV-2 retrieved from the NCBI (National Center for Biotechnology Information) database for this investigation. The experimental outcomes when applying the two methods to the same dataset show that a well-supported and trustworthy phylogenetic tree was obtained with a bootstrapping value of 100% for all branches of the tree when applying the ML method. Additionally, a well-supported and fast-constructing phylogenetic tree was obtained through the NJ method for all branches except one, where the bootstrapping value appeared to be 56%. The research was conducted in 2022 at the College of Science, Diyala University.
The impact of vlogs on travellers’ intentions to use semi-high speed trains: A study on Vande Bharat Express

Published: June 2024

Recently, there has been a lot of buzz on social media, particularly in the form of vlogs, about newly launched semi-high speed trains in India popularly known as Vande Bharat Express. However, no information is available about the extent to which people trust the vlogs promoting the trains and the trains themselves. Therefore, this research aims to investigate the impact of watching vlogs about semi-high speed trains on the trust and attitude towards them, and how they perceive the risks associated. This study is guided by the trust transfer theory to investigate how trust transference can lead to a traveler’s intent to use semi-high speed trains. This study involved 338 participants. The relationship between variables was examined using SmartPLS 4 software. The findings indicate that trust in semi-high speed trains can be established through vlogs leading to intention to use. On the theoretical side, it provides insight into how trust, attitude, and perceived risk can affect the adoption of new technology, while on the practical side, it helps to understand how vlog coverage can be used as a tool to increase trust and ultimately drive adoption. Vlog coverage, trust in vlog content, trust in semi-high speed trains and behavioural intention altogether are not well understood in current literature despite the important implication for managers, academicians and consumers alike. This study contributes to the field of transportation and railways, social media and communication, and hospitality and tourism research. The study helps policy makers to understand users’ characteristics regarding the latest social media tools and adopt them accordingly to provide a better governance policy.
Optimizing the Structures of Transformer Neural Networks Using Parallel Simulated Annealing
Authors: Trzciński Maciej , Łukasik Szymon , Gandomi Amir H.
Published: June 2024

The Transformer is an important addition to the rapidly increasing list of different Artificial Neural Networks (ANNs) suited for extremely complex automation tasks. It has already gained the position of the tool of choice in automatic translation in many business solutions. In this paper, we present an automated approach to optimizing the Transformer structure based upon Simulated Annealing, an algorithm widely recognized for both its simplicity and usability in optimization tasks where the search space may be highly complex. The proposed method allows for the use of parallel computing and time-efficient optimization, thanks to modifying the structure while training the network rather than performing the two one after another. The algorithm presented does not reset the weights after changes in the transformer structure. Instead, it continues the training process to allow the results to be adapted without randomizing all the training parameters. The algorithm has shown a promising performance during experiments compared to traditional training methods without structural modifications. The solution has been released as open-source to facilitate further development and use by the machine learning community.

Das Erinnern an den Holocaust und an andere Genozide ist immer wieder und auch aktuell Gegenstand heftiger Diskussionen. Diese werden jedoch nicht selten im Sinne politischer oder ideologischer Interessen geführt; das Erinnern wird zum Spielball tagespolitischer Auseinandersetzungen. Doch Erinnern ist Ausdruck existentieller Verantwortung. Dieser Einsicht entsprechend wird in diesem Band die ethische Bedeutung des Erinnerns philosophisch reflektiert und eine Ethik des Erinnerns erarbeitet. Die Grundlage hierfür bildet eine kritische Auseinandersetzung mit den Mitteln der Existenzphilosophie.

Published: June 2024

This study evaluates the effects of rabbit compost tea and NPK (15-15-15) fertilizer on the growth parameters of maize (Zea mays L.) at the Teaching and Research Farm of Ekiti State Polytechnic, Isan-Ekiti. The treatments were laid out in a randomized complete block design (RCBD) with three replicates. Each replicate consisted of four (4) treatments. Total land area measured 88 m2 (11 m by 8 m) with 12 plots, and each plot size measured 3 m by 2 m (6 m2) with 1 m alleyways between plots and replicates. The treatments and application rate were the control, rabbit compost tea at 400 l ha-1, a combination of NPK at 100 kg ha-1 and rabbit compost tea at 200 l ha-1, and the application of NPK (15-15-15) fertilizer at the rate of 200 kg ha-1, which was incorporated as the experiment's standard treatment. In the experiment, growth parameters of maize (Zea mays L.) were monitored and evaluated. Findings showed that the application of rabbit compost tea and NPK (15-15-15) fertilizer significantly (p < 0.05) increased the plant height, stem girth, number of leaves, and leaf area when compared with the control, especially when combined. According to this study, rabbit compost tea is an effective and sustainable organic amendment that smallholder maize farmers should consider using to improve growth and output.

Food products that do not require practices for processing, and are easy to prepare have attracted the attention of consumers. An example of this type of product is the premixes formulations for cake mix which allows the cake to be made easily and quickly. The consumer of this type of product has the expectation, when following the instructions, to obtain a uniform and quality product. There are many different chemical leavening agents available to the baker. These include baking soda (sodium bicarbonate), ammonium bicarbonate, potassium bicarbonate, baking powder (baking soda, calcium phosphate and sodium aluminum sulfate) and leavening acids. Generating CO2 and neutralizing sodium bicarbonate is the primary role of leavening acids, but, it is important not to forget their secondary role and their effects. Taking into consideration these facts, the objective of experiments was to establish the connection between quantity and quality of leavening agents and the quality of bakery products. As the chemical leavening agents get into flour, it is also important to comprehend how they influence the rheological parameters of flour with direct implication in the quality of the products made. For experiments, baking powder was used, which was added in specific quantities to wheat flour. The flour samples were made, and the samples obtained were sensory evaluated in the panel. Correlating Mixolab Profiler indices with the baking samples, and also with the legislation regarding, the best results were obtained for flour with 2% baking powder.

The anthropization processes can cause complex, often irreversible changes in natural ecosystems. Several decades ago, on the upper course of the Arges River flowing in the Southern Romania, a series of anthropic interventions took place, which resulted in several new accumulation lakes. Above the socioeconomic benefit to the local communities along the watercourse, their construction also influenced the structure and functioning of the existing ecosystems. In the present study, we have analysed the rate of the detrital organic matter decomposition processes achieved by the heterotrophic microbial communities in several ecosystems located on the upper course of the river. The obtained results revealed that the intensity of these procceses was infleunced both by the type of anthropic area the sampled ecosystems attain - rural or urban, and by the sampling time.
The members of the RAS–RAF–MEK–ERK signaling pathway and cancer
Authors:   Institute of Biology of Romanian Academy, Bucharest, Romania, CONSTANTIN MARIAN
Published: June 2024

Cancer is one of the biggest health problems of contemporary humanity, representing the second cause of death after cardiovascular diseases, caused by many contributing factors, such as population growth, ageing, stress, pollution, unhealthy diet, tumor diversity and heterogenity, difficulties in correct and early diagnosis and inefficiency of current treatments (e.g. cytoreduction, chemotherapy, radiotherapy, etc.). This leads us to look for new ways of dealing with cancer, such as immunotherapy and personalized therapy, which consider the type of tumour, mutations and expression levels of certain genes, making it necessary to detect specific markers. A category of such specific markers is represented by the proteins involved in inter- and intra-cellular signaling which play essential roles in tumor transformation, progression and dissemination. In cancer, some canonical signaling pathways, including RAS-RAF-MEK-ERK, P13K-PKB/AKT, JAK-STAT, HIF1-VEGF, TGFB, NOTCH, RAP1, TP53, B-catenin/WNT, HIPPO, KEAP-NRF2, MYC and CDKN2 (cell cycle), may be dysregulated. In this review, we detail the roles of RAS–RAF–MEK–ERK signaling pathway in tumorigenic processes and the types of abnormalities that affect them in cancer.

Dialyse à domicile et activité physique : état des connaissances et recommandations pour le néphrologue
Authors: Roueff Stéphane , Potfer Erwan
Published: June 2024

La DAD favorise l’autonomie des patients dialysés et devrait s’accompagner, chez ces patients, d’un niveau d’activité physique et de capacités physiques plus élevés qu’en hémodialyse conventionnelle. Il n’existe pas de données concernant les patients en HDQ et chez les patients en DP, on constate un niveau d’activité physique et des capacités physiques similaires aux patients en HD conventionnelle. Il n’existe pas d’étude évaluant l’effet d’un programme de réentrainement chez les patients en HDQ. Plusieurs études ont montré la faisabilité et la sécurité de programmes de réentrainement chez les patients en DP avec des effets bénéfiques sur la qualité de vie et les capacités physiques. La pratique régulière d’une activité physique (AP), 30 minutes, 5 fois par semaine, est recommandée pour les patients dialysés. Toutes les périodes d’AP d’intensité faible à modérée doivent être prises en compte dans le calcul des 30 minutes et il est ainsi possible/souhaitable d’intégrer les AP de la vie quotidienne, les exercices physiques, et les activités sportives de loisirs. C’est le rôle des néphrologues de promouvoir la pratique d’une activité physique régulière envers leurs patients en s’appuyant éventuellement sur des professionnels de l’AP. Il sera de leur compétence d’évaluer la condition physique des patients, leur motivation et en fonction de leur mode de vie, de concevoir des programmes de réhabilitation physique, individualisés pour chaque patient. Ces professionnels superviseront les programmes et autonomiseront les patients vers un mode de vie plus actif par une activité physique régulière. Le manque d’étude ne doit pas être un frein pour les néphrologues qui pourront s’appuyer sur des recommandations existantes issues de cardiologie et de l’ISPD.

In synergistic catalysis, multiple catalysts or active sites work together to produce ‘the whole is greater than the sum of its parts’ effect. However, the trilemma of flexibility-stability-cost lies ahead of the multiunit heterogeneous catalyst. As complexity increases, the catalytic efficiency tends to be restricted. Here, we report a general method to tailor modular metallaphotoredox catalysts. The dyes and molecular catalysts could flexibly connect with inexpensive carbon nitride via stable covalent bonds, like LEGO® games. Tunable visible-light absorption, high electron-hole separation efficiency and steerable construction of catalytic active sites have been realized simultaneously, meanwhile the electron transfer mechanism has been clarified via operando techniques. By precisely regulating the coordination field of single-atom sites, four different metallaphotoredox-enabled C-C cross-couplings could be compatible with good cyclic stability (up to 150 hours) and anti-interference ability.
Partial ordering of isovalent Cd and Mn atoms in the quater-nary phase Eu2Mn1–xCd1+xPt2 (x = 0.11) with LaNiAl type struc-ture
Authors: Ponou Simeon , Mudring Anja-Verena
Published: June 2024

After attempts to synthesize the imaginary ternary phase “EuMnPt” failed, the solid solutions EuMnxCd1–xPt were prepared following speculations that random mixing of the divalent Cd and Mn metals may be achieved in the previously reported analogue EuCdPt (TiNiSi type, Pnma–c3). However, an unexpected atomic ordering resulted in the quaternary phase Eu2Mn1–xCd1+xPt2 (x = 0.11) which adopts the Pd2(Mn,Pd)Ge2 (or LaNiAl, Pnma–c6) structure type instead, in which two mixed Mn/Cd sites in the structure show pronounced site preference, reminiscent to that of Mn/Pd sites in the prototype. Thus, the crystal structure of Eu2Cd1+xMn1–xPt2 (x = 0.11) represents a unique example of 4f-3d-4d-5d intermetallic system with nearly complete atomic ordering, and it may be best viewed as an intergrowth of hexagonal ZrNiAl type (previously reported for CeCdxMn1–xPt) and orthorhombic TiNiSi type (previously reported for YbCdxMn1–xPt). It is also the first Eu based compound to adopt the LaNiAl type structure, reported only with the earlier lanthanides (Ln = La, Ce, Pr, Nd), and all noble metals of the Pt group, but Os and Pt itself. The sublattice of paramagnetic Mn atoms consists of linear zigzag chains with Mn–Mn distance of 3.084(1) Å, while triangular magnetic geometrical frustration is realised in the Eu sublat-tice. Thus, the rather unexpected atomic segregation between two isovalent transition metals Mn (3d5) and Cd (4d10) may be ascribed, at first glance, to bonding preference for homonuclear Mn–Mn over heteronuclear Mn–Cd interactions, in agreement with the 18–n rule.
Accurate and Efficient Open-Source Implementation of Domain-Based Local Pair Natural Orbital (DLPNO) Coupled-Cluster Theory Using a t1-Transformed Hamiltonian
Authors: Jiang Andy , Glick Zachary , Poole David , Turney Justin , Sherrill David , Schaefer Henry
Published: June 2024

Here, we present an efficient, open-source formulation for coupled-cluster theory through perturbative triples with domain-based local pair natural orbitals [DLPNO-CCSD(T)]. Similar to the implementation of the DLPNO-CCSD(T) method found in the ORCA package, the most expensive integral generation and contraction steps associated with the CCSD(T) method are linear scaling. In this work, we show that the t1-transformed Hamiltonian allows for a less complex algorithm when evaluating the local CCSD(T) energy without compromising efficiency or accuracy. Our algorithm yields sub-kJ mol-1 deviations for relative energies when compared with canonical CCSD(T), with typical errors being on the order of 0.1 kcal mol-1, using our TightPNO parameters. We extensively tested and optimized our algorithm and parameters for non-covalent interactions, which have been the most difficult interaction to model for orbital (PNO)-based methods historically. To highlight the capabilities of our code, we tested it on large water clusters, as well as insulin (787 atoms).
Accurate measurement of sequential Ar desorption energies from the dispersion-dominated Ar1-3 complexes of 1-naphthol
Authors: Baweja Simran , Kalal Bhavika , Maity Surajit
Published: June 2024

We devise a unique experimental methodology to accurately measure the sequential desorption of Ar atoms from the aromatic surface of 1-naphthol (NpOH). The dispersion-dominated NpOH·Ar1-3 complexes were characterized using resonant two-photon ionization (R2PI) spectroscopy in the gas phase. The band origins 〖(0〗_0^0) for S1←S0 transition in the NpOH·Ar, NpOH·Ar2 and NpOH·Ar3 complexes were observed at 31440, 31425 and 31415 cm-1, respectively. The above values were red-shifted by 15, 30 and 40 cm-1 () compared to that of the NpOH (0_0^0 at 31455 cm-1) molecule. The disappearance of Franck-Condon active vibrational bands in the R2PI spectrum was utilized to determine the D0(S1) values of non-covalently bound molecular complexes. The single Ar desorption energies from the NpOH·Ar, NpOH·Ar2 and NpOH·Ar3 complexes were measured as 487 5, 471 21 and 442 24 cm-1, respectively. The corresponding dissociation energies D0(S1) were measured as 487 5, 958 26 and 1400 50 cm-1. The D0(S0) values were determined by subtracting the shift of the origin band, and the respective values are 472 5, 928 26 and 1360 50 cm-1. The preferable orientation for the efficient desorption was obtained with the first Ar atom positioned on the top face of the NpOH ring. A second Ar atom was bound to the bottom face of the NpOH ring. The docking of third Ar atom could be on the NpOH face above OH (I1), CH (I2) or π (I3), as all these structures are isoenergetic to each other. The best correlation of the experimental and calculated dissociation energies of NpOH·Ar1-3 (I1) complexes is obtained at the B-LYP-D4/def2-TZVPP level of theory, with an accuracy of 3-5%. The current study provides an inexpensive laser spectroscopic method to precisely determine the dissociation energies of the dispersively bound complexes of biorelevant aromatic molecules based on their Franck-Condon activity
Evaluation of Hydraulic Structures for Agricultural Discharge Optimization
Authors: Kazem Fatima H. , Maatooq Jaafar S. , Wahad Mohammed S.
Published: June 2024

The objective of the research was to evaluate the hydraulic structures on the Al-Gharraf River in southern Iraq and their ability to achieve the required discharge for agricultural areas that depend on them. Al-Gharraf head regulator discharges unstable volumes of water, ranging from 280 m3/s in winter to 100 m3/s in summer. The research aimed to determine whether the operational discharges are achievable for the offtakes branching from the Al-Gharraf River when the river's discharge ranges from 60% to 100% of the operational discharge. The researchers utilized a simulation of the irrigation channel (SIC) model to simulate river flow. The researchers used hydraulic indicators such as Delivery Performance Ratio (DPR), Discharge Deviation (∆Q), and Sensitivity (S) to evaluate the work of the hydraulic structures (regulators), determine the more and less efficient regulators in delivering water to the offtakes, and determine the reasons for inefficiency. Depending on the discharge values for each offtake from simulation results by SIC and calculating the hydraulic indicators, it is observed that some offtakes exceed their operational discharges, such as Al-Zydia and Al-Sabila. Also, some offtakes do not receive their operational discharge (Al-Dawaiya, Shatt Al-Shatra, and Al-Basra) projects, which failed to reach even 10% of their operational discharges. The researchers suggest redesigning some offtakes and ensuring reasonable control of gate openings for other offtakes to make the water distribution proportional. Doi: 10.28991/CEJ-2024-010-05-010 Full Text: PDF

Published: June 2024

A circular, hollow tubular steel column is introduced for experimental and analytical analysis in this study. A series of axial compression tests for the variation of static schemes are reported in this study. All theoretical, numerical, and experimental analyses are based on the European Standards for the steel structure, respectively EN 1993-1-1. The experimental models of steel columns are conducted on actual steel columns with a length of 3000 mm and a circular hollow section of 114.3/2.8 mm. To assess the behavior and stress values of the columns, various schematically supported systems are modeled, starting from the axial-centered columns to the symmetrical eccentric load and asymmetrical loaded columns. 3D modeling of the steel columns using the finite element program SEISMOSOFT is also developed for such elements. The accuracy of the model is compared with the experimental results using numerical analysis by the finite element method. Finally, the numerical comparison of the results provides a recommendation for the engineers regarding the design and construction of such columns. Doi: 10.28991/CEJ-2024-010-05-014 Full Text: PDF
Optimizing Gene Expression Programming to Predict Shear Capacity in Corrugated Web Steel Beams
Authors: Shrif Mazen , Al-Sadoon Zaid A. , Barakat Samer , Habib Ahed , Mostafa Omar
Published: June 2024

Corrugated web steel systems, such as corrugated web girders (CWG) and beams (CWSB), have the potential to influence the modern construction industry due to their unique properties, including enhanced shear strength and reduced necessity for transverse stiffeners. Nevertheless, the lack of a rapid and accurate design approach still limits its wide applications. Recently, gene expression programming (GEP) has been employed to predict the shear capacity of cold-formed steel channels, demonstrating superior predictive accuracy and compliance with established standards. This study applies GEP to predict the shear capacity of sinusoidal CWSBs and optimizes its predictive performance by employing a systematic grid search to explore combinations of chromosomes, head sizes, gene counts, and linking functions. The process involved testing 19 different parameter combinations and more than 60 developed models. The findings include the sensitivity of the model's performance to gene count and the critical role of the linking function. The optimal model in the study, GEP13, achieved R² of 0.95, an RMSE of 100.5, and an MAE of 86.6 in the testing dataset with 150 chromosomes, a head size of 12, and four genes using a multiplication linking function. Doi: 10.28991/CEJ-2024-010-05-02 Full Text: PDF
Integration of Blockchain-Enabled Smart Contracts in Construction: SWOT Framework and Social Network Analysis
Authors: Ghaly Monica , Elbeltagi Emad , Elsmadony Adel , Tantawy Mohamed A.
Published: June 2024

The construction sector, one of the most ancient industries globally, holds a crucial role in the progress and development of societies. However, it faces persistent productivity and efficiency challenges, rendering it a relative setback when compared to other sectors. In the ever-evolving landscape of the construction industry, characterized by complex projects, numerous stakeholders, and intricate contractual agreements, the integration of emerging technologies presents an unprecedented opportunity for transformation. Smart contracts (SCs), underpinned by blockchain (BC) technology, hold the potential to streamline and revolutionize traditional construction processes. Current literature shows a lack of comprehensive quantitative understanding of how Blockchain-enabled Smart Contracts (BSC) can affect the construction sector. To address this gap, the authors have (1) conducted a systematic keyword analysis of literature on SC in construction from Scopus and Web of Science (WoS) databases; (2) conducted a strengths–weaknesses–opportunities–threats (SWOT) analysis of BSC’s adoption in the construction industry from 174 peer-reviewed papers; (3) identified a holistic list of 72 factors steering BSC adoption in construction, categorized into the 4 aspects of the SWOT framework; (4) performed social network analysis (SNA) to quantitively assess the literature in terms of the identified factors; and (5) conducted clustering analysis to categorize combination of factors frequently highlighted in research publications into common groups. This research offers a comprehensive and methodical evaluation of the potential advantages, applications, and challenges associated with integrating BSC in the construction industry. The findings of SNA and clustering reveal a notable lack of investigation into certain combinations of factors in existing academic research. This disparity and the ensuing knowledge gaps may affect SC’s adoption in the construction sector. To this end, this study equips stakeholders with the insights necessary to make informed decisions in this rapidly evolving sector and contributes to a roadmap for future BSC construction-related research. Doi: 10.28991/CEJ-2024-010-05-020 Full Text: PDF

Central Java was in second position as the province with the highest number of poor people in Indonesia in March 2020. Poverty alleviation efforts have been carried out, but many are still not yet on target. The purpose of this study was to model the classification of household poverty status in Central Java using CHAID and random forest methods and compare the two methods. The data used in this study is data from the 2020 National Socioeconomic Survey (SUSENAS) conducted by the Central Bureau of Statistics (BPS) for Central Java. The number of poor households is much less than non-poor households. Therefore, Synthetic Minority Oversampling Technique (SMOTE) was performed to handle unbalanced data. The random forest method produced better classification performance than the CHAID method with accuracy, sensitivity, specificity, and AUC of 93,95%, 98,43%, 89,92%, and 0,9417, respectively. The important variables that build the random forest model are the floor area of the house, the age of the head of the household, cooking fuel, the place for the final disposal of feces, and ownership of the place to defecate.

Spatial dependence and spatial heteroskedasticity are problems in spatial regression. Spatial autoregressive regression (SAR) concerns only to the dependence on lag. The estimation of SAR parameters containing heteroskedasticity using the maximum likelihood estimation (MLE) method provides biased and inconsistent estimators. The alternative method that can be used are generalized method of moments (GMM) and Bayesian method. GMM uses a combination of linear and quadratic moment functions simultaneously so that the computation is easier than MLE. Bayesian method solves heteroskedasticity by modeling the structure of variance-covariance matrix. The bias are used to evaluate the GMM and Bayes in estimating parameters of SAR model with heteroskedasticity disturbances in simulation data. The results show that GMM and Bayes provides the bias of parameter estimates relatively consistent and smaller with larger number of observations. GMM and Bayes methods are applied to district/city GRDP data in Indonesia. The result show GMM method with Eksponential Distance Weights (EDW) matrix produces the minimum variance and the largest pseudo-R2
The "Us" and "Them" Divide: Rethinking the Role of Young People in Religious Conflicts in Nigeria
Authors: Omopo Bimbo Stanley , Ekpo Charles E.
Published: June 2024

ABSTRACT: As a value-based problem, religious conflicts are disruptive and protracted. Indeed, Nigeria has experienced a plethora of protracted religious conflicts since independence in I960. Constituting major actors in these conflicts are young people, who play critical roles in fomenting and escalating them. Although extant literature acknowledges this preponderant place of young people in these conflicts, it tends to negate the potential constructive roles they play in managing the conflicts. This paper explores the disruptive and potential constructive roles of the youths as principal actors in religious conflicts in Nigeria. It argues that if armed with the right education on peace and tolerance, young people can play critical preventive and curative roles in religious conflict theaters in Nigeria. Exploring these youths' strengths is pertinent for a multidimensional approach to addressing religious conflicts and violence in Nigeria .

In today's world, where regional development plays an important role in sustainable economic growth and social progress, the issue of involving stakeholders in the process of strategic development of regions becomes particularly relevant. The concept of stakeholder management recognizes that a successful regional development strategy requires the participation of various stakeholders, from local residents and businesses to public organizations and government structures. Stakeholders in the context of regional development represent a wide range of interests, goals and needs, which can often conflict with each other. Therefore, it is important to establish mechanisms of cooperation and interaction between these parties to achieve common goals and solve the problems facing the region. Involvement of stakeholders in the process of strategic development of regions is not limited to simple collection of opinions and opinions of different groups. This is a complex process that involves the creation of mechanisms for actively taking into account the views and interests of various stakeholders when making strategic decisions. The main goal is to study the key aspects of the concept of stakeholder involvement in the process of strategic development of regions, including the definition of stakeholders, their role in regional development, methods of involvement and interaction with different types of stakeholders, as well as challenges and obstacles that may arise along the way. Understanding these aspects will allow us to more deeply analyze the essence and effectiveness of the practices of involving stakeholders in the process of regional development, as well as to determine ways to overcome possible obstacles and maximize the positive impact of this process on the sustainable growth and prosperity of regions.

Automatic temperature regulation system is crucial to optimize the anaerobic fermentation process and maximize biogas production. In this study, we implemented an automatic system integrating GSM technology to enable remote temperature control and regulation. For this, we installed a temperature sensor inside the biodigester in order to monitor these thermal variations, the data collected by this sensor is transmitted to the central control system via an Arduino Uno module. The latter compares the received data with predefined thresholds and accordingly sends adjustment commands to the heating system. Operators can monitor and adjust temperature parameters remotely via SMS messages through the SIM800 GSM module. Through this system, the temperature of the biodigester can be maintained at optimal levels, thereby promoting efficient digestion of organic materials and continuous production of biogas, while providing convenient and responsive remote management.
