Authors: Urbański Aleksander , Richter Mateusz
Published: March 2024

In this paper, the authors present an extension of the scope of the previously conducted research to the full three-dimensional computer simulation (using the finite element method), which takes into account the interaction between: heavy caterpillar tracks system – working platform – weak subsoil. The article presents a computer model considering two caterpillars, resting on elastic-plastic sub-soil, with standard Mohr-Coulomb yield conditions, allowing for computer simulation of the behavior of the system up to achievement of ultimate limit state. The results of the above model are treated as the reference for a simplified Analytical Models of estimating the limit state, which might be used in design procedures. In turn, these Analytical Models are enhancements of previously presented one. The most important results concluding form the Analytical Model are simple interaction formulas, in the space of moments acting on the machine-subsoil system, limiting a domain of safety in given soil conditions.
A new multi-attribute group decision-making method based on probabilistic multi-valued linguistic spherical fuzzy sets for the site selection of charging piles
Authors: Feng Xue , Liu Shifeng , Xu Wuhuan
Published: March 2024

Motivated by the concepts of low carbon and environmental protection, electric vehicles have received much attention and become more and more popular all around the world. The expanding demand for electric vehicles has driven the rapid development of the charging pile industry. One of the prominent issues in charging pile industry is to determine their sites, which is a complex decision-making problem. As a matter of factor, the process of charging piles sites selection can be regarded as multi-attribute group decision-making (MAGDM), which is the main topic of this paper. The recently proposed linguistic spherical fuzzy sets (LSFSs) composed of the linguistic membership degree, linguistic abstinence degree and linguistic non-membership degree are powerful tools to express the evaluation information of decision makers (DMs). Based on the concept of LSFSs, we introduce probabilistic multi-valued linguistic spherical fuzzy sets (PMVLSFSs), which can describe DMs’ fuzzy evaluation information in a more refined and accurate way. The operation rules of PMVLSFSs are also developed in this article. To effectively aggregate PMVLSFSs, the probabilistic multi-valued linguistic spherical fuzzy power generalized Maclaurin symmetric mean operator and the probabilistic multi-valued linguistic spherical fuzzy power weighted generalized Maclaurin symmetric mean are put forward. Based on the above aggregation operators, a new method for MAGDM problem with PMVLSFSs is established. Further, a practical case of suitable site selection of charging pile is used to verify the practicability of this method. Lastly, comparative analysis with other methods is performed to illustrate the advantages and stability of proposed method.

Authors: Xiong Hui , Shi Lushan
Published: March 2024

In the quest for sustainability, managing and optimizing energy consumption within green buildings has emerged as a critical area of focus. The complexity of factors affecting energy use demands more sophisticated analysis than what traditional methods offer. This study leverages the DEMATEL method to isolate crucial influencing factors. It employs the ISM method to map their logical interconnections, forming a comprehensive model of energy consumption determinants in green buildings. We identify building design, energy efficiency, and green technology as critical elements, with building design exerting the most influence (weight: 0.35). Through an in-depth fuzzy DEMATEL-ISM analysis, we develop specific energy-saving measures—such as design improvement and technology enhancement—that promise up to a 20% reduction in energy consumption. Our research introduces a groundbreaking green building energy management tool and provides a solid foundation for policy development and practical applications.

The Impact of Foreign Trade on Carbon Productivity Based on VAR Model
Authors: Zhao Xiujuan
Published: March 2024

Global carbon emissions and climate change are of increasing concern. As a critical indicator of the carbon efficiency of economic activities, carbon productivity has improved, resulting in a relative reduction in carbon emissions and output growth. As an essential part of the national economy, foreign trade profoundly impacts carbon productivity by promoting technology exchange, industrial upgrading, and structural adjustment. The carbon emission impact of foreign trade is not uniform, and there are noticeable differences between countries and regions. This paper examines how foreign trade affects carbon productivity and through which mechanisms, and further analyzes regional and industrial differences in these effects to provide a basis for the formulation of relevant policies. According to the study, there is a significant time lag effect on foreign trade’s impact on carbon productivity, and there are differences between industries and regions. Promoting foreign trade in this paper results in technological progress and improved carbon productivity, with an average improvement of 5.2%. By optimizing and adjusting industrial structure, carbon productivity is promoted better, with an increase of around 4.3%. High carbon emission industries have a relatively weak positive effect. Foreign trade positively impacts carbon productivity by promoting technological progress and industrial restructuring, but it is necessary to have differentiated policies for different industries and regions.

Spotlight on Controversy in Black Crime in America
Authors: Xin Jueru , An Xin
Published: March 2024

The issue of crime within African American communities in the United States is both longstanding and multifaceted, attracting widespread attention and generating significant debate. This paper navigates through the complexities of this issue, critically examining diverse perspectives and contributing our analysis from three key dimensions. We explore the historical context of the War on Drugs and its disproportionate impact on African Americans, including the subsequent rise in mass incarceration. Additionally, we investigate the influence of mass incarceration on violent crime rates and the cultural phenomenon of the “Code of the Street” in African American neighborhoods. Furthermore, we argue for developing a distinct African American criminology to provide a more nuanced understanding of these issues. Our analysis goes beyond identifying structural disadvantages faced by African Americans, proposing a vision for resilience and moral resurgence amidst adversity.
A Study of the Ethics of Contemporary American Women’s Cinema
Authors: Gao Weihua
Published: March 2024

As one of the essential mediums of global cultural communication, American films, especially those involving women’s themes, have played a key role in shaping and transmitting women’s images and ethical concepts. The diversity of women’s roles and deep-seated emotions in contemporary American films with women’s themes is reflected in changes in society’s understanding of women’s status and rights. This paper aims to examine the impact of ethical views presented in contemporary American female-themed films on society and the audience. By collecting and analyzing popular American female-themed films in recent years, it explores ethical issues and the portrayal of women in the movie. Of the 100 films studied, more than 60% present a strong ethical tendency towards female self-identification and autonomous choice, with 40% showing a clear tendency towards gender equality and anti-discrimination. We find that the images of resilience and independence shown by female characters in movies in the face of difficulties and challenges have positively impacted the values and behavioral patterns of predominantly female audiences. Contemporary American women’s films not only reflect the current social concern and exploration of women’s issues, but also promote the public’s awareness of gender equality and women’s rights through the portrayal of diversified and profound women’s images, and provide an essential perspective for the promotion of social progress and the development of cultural pluralism.

Authors: Ignatowski Grzegorz , Stopczyński Bartłomiej , Sułkowski Łukasz
Published: March 2024

Objective

The subject of this article is the marketing aspect of familiness related to building the image of a family business brand. The aim of the article is to analyze the impact of familiness in the activities connected with building the brand image of small and medium-sized family businesses.

Methodology

Qualitative and quantitative methods have been included in the conducted research.

Findings

The research has shown that Facebook is used by the vast majority of companies. This research has also demonstrated that a large percentage of companies do not emphasize the familiness of their company in their activities on social media. This is surprising because the analysis of the literature shows that emphasizing the family character brings definitely more benefits than risks.

Value Added

This article presents a research of how family-owned companies use familiness in the brand image. The results of the research can be used to guide companies on how to use familiness in their social media marketing campaigns.

Recommendations

It is recommended that family businesses make greater use of the potential of their family strengths. It would be advisable to conduct research explaining why the family nature of companies is so rarely emphasized in social media activities. We also suggest conducting similar research in other countries, which would allow for more general conclusions and capture cross-cultural differences.
The Concept of Public Trust-Based Leadership – An Outline
Authors: Kożuch Barbara
Published: March 2024

Objective

The issue of trust in leading public organisations continues to inspire growing confidence among management researchers and practitioners. The characteristics and organisational behaviour of leaders are analysed from various angles. The subject of the research is one of the newer approaches, namely trustbased leadership (TBL). The aim of this paper is to identify characteristics and the roles of public trust-based leadership (PTBL). This is the type of leadership that most fully incorporates trust as the basis of organisational behaviour in vertical and horizontal relationships and consequently as organisational cooperation.

Methodology

The primary methods used in this article are a critical review of research on organisational trust, leadership and public trust contained in the academic literature and in surveys of trust in leadership conducted in recent years by consultancies and made available on line.

Findings

The study confirmed that an inalienable role of leaders is to shape their own organisational credibility in both internal and external relations. Achieving a high level of this credibility allows to earn trust.

Value Added

Demonstrating that a key differentiator of the trust-based leadership concept is that TBL is centring trust-based relationships throughout the entire organisation.

Recommendations

Further research on trust-based public leadership should support its presence in contemporary organisations.
Financial Education and Banking Inclusion during the Pandemic Period
Authors: Kuchciak Iwa
Published: March 2024

Objective

The aim of this publication is to present the importance of financial education as it relates to influencing the level of banking inclusion during the COVID-19 pandemic. The individual sections of the article will characterize financial education as a driving force for improving financial literacy and highlight the link between financial literacy and the level and extent of use of financial products. The paper will consider the current situation on the financial markets, which is characterized by the COVID-19 pandemic.

Methodology

The first part of this paper is based on the systematic literature review, including scientific papers related to financial education, derived from the Web of Science databases, mapping analysis and bibliographic coupling using the Voswiever. The second part presents the results collected through an interview designed and disseminated to a sample of banking advisors.

Findings

The majority of interviewees encountered the concept of banking exclusion/inclusion, and in terms of characteristics that predispose one to remain excluded, advisors emphasized economic considerations. In various extracts from the interviews, banking advisors emphasized the importance of addressing the ability to afford banking services, their innovativeness, as well as understanding how banking products work, the benefits of entering into a relationship with a bank, and the prudent use of banking products on the basis of financial literacy.

Value Added

The value added is a multi-approach that combines the theoretical aspects of financial exclusion and financial literacy with the actual opinions of banking advisors.

Recommendations

Increased financial education is needed due to the complexity of financial products and their dynamic changes. The increased frequency and scope of use of financial products has increased the risk of cyber-attacks, against which financial literacy and risk awareness are needed. The development of modern technology in banking has increased the risk of banking exclusion for the digitally excluded. Financially well-educated consumers are more likely to be included in the banking system, as they are better able to understand and use financial information to make financial decisions, and to choose products and services that are more appropriate to their needs and risk profile.
Migration of health workers: key findings from Romania
Authors: Boboc Cristina , Ghiță Simona Ioana , Vasile Valentina
Published: March 2024

The migration of medical staff results in the diminution of human resources in the health sector, undermining the capacity of developing countries' health systems to provide medical services equitably. Various factors, such as economic, professional, political, social, or personal considerations, contribute to the decision of health workers to emigrate. This paper's primary objective is to analyze the prevailing trends in the migration flows and stocks of physicians and nurses, with a focus on identifying the principal pull factors of migration. The preferred destination countries for Romanian health professionals include the UK, Germany, France, and Italy. Notably, Germany stands out as a leader in health care professionals' migration flows, characterized by two distinct migration periods: the first featuring exceptionally high levels of physician migration and the second marked by increasing levels of nurses' migration. Through panel data regression analysis, we have established that the pull factors for physicians differ from those for nurses. For physicians, the presence of a Romanian community of health professionals in the destination countries is crucial, whereas for nurses, the development level of the destination country holds top importance.
Effects on of Blended Biodiesel and Heavy Oil on Engine Combustion and Black Carbon Emissions of a Low-Speed Two-Stroke Engine
Authors: Wei Cunfeng , Jiang Guohe , Wu Gang , Zhou Yu , Liu Yuanyuan
Published: March 2024

The effects of heavy fuel oil and biodiesel blends on engine combustion and emissions were studied in a marine two-stroke diesel engine. The engine was operated under propeller conditions using five different fuels with biodiesel blends of 10% (B10), 30% (B30), 50% (B50), and sulphur contents of 0.467% low sulphur fuel oil (LSFO) and 2.9% high sulphur fuel oil (HSFO). Tests have shown that using a biodiesel blend increases the engine fuel consumption due to its lower calorific value. Heavy fuel oil has a high Polycyclic aromatic hydrocarbons (PAH) content, which leads to higher exhaust temperatures due to severe afterburning in the engine. A comparison of engine soot emissions under different fuel conditions was carried out, and it was found that the oxygen content in biodiesel promoted the oxidation of soot particles during the combustion process, which reduced the soot emissions of biodiesel. Compared to HSFO, B10, B30, B50 and LSFO, the soot emission concentrations were reduced by 50.2%, 56.4%, 61% and 37.4%, respectively. In our experiments, the soot particles in the engine exhaust were sampled with a thermal float probe. Using Raman spectroscopy analysis, it was found that as the biodiesel ratio increased, the degree of carbonisation of the soot particles in the exhaust became less than that in the oxygenation process, resulting in a decrease in the degree of graphitisation.
Fault Diagnosis of Imbalance and Misalignment in Rotor-Bearing Systems Using Deep Learning
Authors: Liu Fayou , Li Weijia , Wu Yaozhong , He Yuhang , Li Tianyun
Published: March 2024

Rotor-bearing systems are important components of rotating machinery and transmission systems, and imbalance and misalignment are inevitable in such systems. At present, the main challenges faced by state-of-the-art fault diagnosis methods involve the extraction of fault features under strong background noise and the classification of different fault modes. In this paper, a fault diagnosis method based on an improved deep residual shrinkage network (IDRSN) is proposed with the aim of achieving end-to-end fault diagnosis of a rotor-bearing system. First, a method called wavelet threshold denoising and variational mode decomposition (WTD-VMD) is proposed, which can process original noisy signals into intrinsic mode functions (IMFs) with a salient feature. These one-dimensional IMFs are then transformed into two-dimensional images using a Gramian angular field (GAF) to give datasets for the deep residual shrinkage network (DRSN), which can achieve high levels of accuracy under strong background noise. Finally, a comprehensive test platform for a rotor-bearing system is built to verify the effectiveness of the proposed method in the field. The true test accuracy of the model at a 95% confidence interval is found to range from 84.09% to 86.51%. The proposed model exhibits good robustness when dealing with noisy samples and gives the best classification results for fault diagnosis under misalignment, with a test accuracy of 100%. It also achieves a higher testing accuracy compared to fault diagnosis methods based on convolutional neural networks and deep residual networks without improvement. In summary, IDRSN has significant value for deep learning engineering applications involving the fault diagnosis of rotor-bearing systems.

Authors: Genç Yusuf , Kafali Mustafa , Çelebi Uğur Buğra
Published: March 2024

It is critical to estimate the workforce requirements for the production of blocks in shipbuilding. In this study, the number of workforce (man-day) required for the production of a passenger ship’s double bottom block was estimated. Initially, the production of the block was observed, and the average working performance of the mounting, welding, and grinding workers was recorded. Block drawings were examined and the work required was calculated. The amount of work increased, depending on any revisions required due to incorrect or incomplete designs. The average working performance of an employee is uncertain due to environmental factors, including the weather and working conditions, as well as health (both physical and mental). A two-stage stochastic programming model with recourse was established to estimate man-day required and a Sample Average Approximation (SAA) technique was used to obtain a near-optimum solution. The results of the study were compared with shipyard records and an agreement of approximately 90% was achieved.
Prognostic factors for overall survival and safety of trans-arterial chemoembolization (TACE) with irinotecan-loaded drug-eluting beads (DEBIRI) in patients with colorectal liver metastases
Authors: Sljivic Maja , Sever Masa , Ocvirk Janja , Mesti Tanja , Brecelj Erik , Popovic Peter
Published: March 2024

Background

Transarterial chemoembolisation with irinotecan-loaded drug-eluting beads (DEBIRI TACE) can be considered in patients with unresectable colorectal cancer liver metastases (CRLM) who progress after all approved standard therapies or in patients unsuitable for systemic therapy.

Patients and methods

Between September 2010 and March 2020, thirty patients (22 men and 8 women; mean age 66.8 ± 13.2) were included in this retrospective study. DEBIRI TACE was conducted in 43% of patients unsuitable for systemic therapy as a first-line treatment and 57% as salvage therapy after the progression of systemic therapy. All the patients had liver-limited disease. In the case of unilobar disease, two treatments were performed at four-week intervals, and in the case of bilobar disease, four treatments were performed at two-week intervals. All patients were premedicated and monitored after the procedure. Adverse events were graded according to the Cardiovascular and Interventional Radiological Society of Europe (CIRSE) classification system for complications.

Results

The median overall survival (OS) from the beginning of DEBIRI TACE in the salvage group was 17.4 months; in the group without prior systemic therapy, it was 21.6 months. The median overall survival of all patients was 17.4 months (95% confidence interval [CI]: 10.0–24.7 months), and progression-free survival (PFS) was 4.2 months (95% CI: 0.9–7.4 months). The one-year survival rate after the procedure was 61%, and the two-year rate was 25%. Univariate analysis showed better survival of patients with four or fewer liver metastases (p = 0.002). There were no treatment-related deaths or grade 4 and 5 adverse events. Nonserious adverse events (Grades 1 and 2) were present in 53% of patients, and Grade 3 adverse events were present in 6% of the patients.

Conclusions

DEBIRI TACE is a well-tolerated treatment option for patients with liver metastases of colorectal cancer. Patients with four or fewer liver metastases correlated with better survival.
Ceramic Dishes Were from the Don Settlements of Gorodets Culture
Authors:   Voronezh State Pedagogical University. Lenin St., 86, Voronezh, 394043, Russian Federation, Razuvaev Yury D.
Published: March 2024

The author characterizes the ceramic complex of the Gorodets culture settlements, widespread in the second half of the 1st millennium BC in the forest-steppe part of the Don basin. It consists of molded earthenware for kitchen purposes; there are practically no tableware. The pottery had both a smoothed and relief-shaped outer surface (“matting”, “mesh”, “grooved”). The main mineral impurity added to the molding mass during their manufacture was grus (crushed mineral rocks). Sand and chamotte (crushed ceramics) were often used. The dominant type of dishes were pots, the appearance of which is given by 24 reconstructed specimens. Three main and several single varieties of shape of these vessels have been identified. Less numerous are jars and cups, of which three were found in their “whole” form. A significant part of the vessels were undecorated, but most ones were decorated with finger tucks, notches, punctures. The spread of well-profiled pots in the Gorodets environment, which replaced jar forms, is explained by economic interaction with the Scythian culture, whose area covered the southern part of the region.

The article deals with the paleoanthropological analysis of the skeletons unearthed from the Myntobe necropolis and dated to the II – IV centuries AD. Myntobe necropolis is located 2 km south of Gani Muratbayev village in the Keles district of Turkestan province. The burial ground consists of more than 600 randomly located mounds of various sizes. All mounds have a dirt embankment. Archaeological excavations were carried out at the burial ground in 2017 and 2022, as a result of which burials in the catacombs and naus were unearthed. An analysis of the burial tradition and recovered material allows researchers to speak about the belonging of these burials to the Kangli tribes. Since the burials date back to the Kangli period, the theoretical part reveals the issues of the location and political structure of the tribes and, most importantly, the determination of the paleopathology of the Myntobints by conducting a macroscopic analysis of the discovered skeletons. The results of the analysis allowed for drawing preliminary conclusions about lifestyle, social life, and nutritional status. When writing the theoretical part of the article, electronic textbooks and resources from the book fund of the National Library of Kazakhstan and the library of the International Kazakh-Turkish University named after Kozh Ahmet Yasawi were used. In total, 9 skeletons were selected for paleoanthropological and paleopathological analysis, from mounds No. 3, No. 6, and No. 7. Paleoanthropological reasoning in the main section is written on the basis of materials in Turkish and English from the collections of Turkish libraries. The skeletons found were analyzed macroscopically and many diseases were identified, such as osteoarthritis (joint deformity), osteopathy, ankylosing spondylitis, heel spurs, thickening of the cranial bone, and deformity of the mandibular joint. Preliminary conclusions about the paleopathology of the discovered skeletons are made.

The article presents the study of the collection of bladed weapons, obtained during the excavations of the Rouran period burials on Choburak-I necropolis. This site is located in the Chemal district of the Altai Republic. The analyzed series of weapons includes three swords and six combat knives found in the burials of four adult men and one teenager. It has been established that the complex of long-bladed weapons is represented by single-edged blades without crosshairs and pommel, with a semi-segmental tip. The surviving combat knives with a triangular blade section are divided into two types, distinguished by a straight handle and a handle inclined towards the blade. The published collection demonstrates typical examples of weapons of the nomads of Central Asia of the 4th – 5th centuries AD. New excavation materials confirm the thesis that swords were a status category of weapons among the population of Altai during the Great Migration period. Burials with such items, investigated as part of the Choburak-I necropolis, differed in the representative composition of the inventory, and, judging by the available data, belonged to military leaders or especially distinguished professional soldiers.

The article presents the results of the analysis of the study of the image of fish in the rock art of ancient hunters and fishermen of Northern Europe (final VI – III BC). During the study, 134 fish figures were studied on 6 rock paintings and in 17 clusters of petroglyphs of Fennoscandia. The small proportion of fish figures in relation to the total number of images on the rocks of the region, with a high proportion of fishing in the primitive economy, established by bone remains at Neo-Eneolithic sites, suggests a mythological basis for the images under consideration. Spatial differences in the appearance of fish figures in Northern Europe make it possible to distinguish two areas (western and eastern), radically different in the style of the ichthyomorph image. The rock art mainly reflects representatives of the largest fish species that lived in the region: catfish, sturgeon, halibut, pike, salmon, whitefish. In the bone remains at the sites located near the clusters of rock carvings, other types of fish are usually dominant: zander, cod. In the compositions of fishing, as in other hunting scenes carved on the petroglyphs of Fennoscandia, only active methods of its extraction are presented, although there is numerous archaeological evidence of the use by the inhabitants of the region for catching fish and other animals of various types of traps.

Early detection of perinatal testicular torsion (PTT), early use of Doppler US, and a shorter decision-making process achieved with early involvement of pediatric surgery/urology may affect prognosis, especially in the postpartum PTT setting. Considering that 3% asynchronous bilateral PTT rates have been reported in the literature, early consultation and ultrasonography are recommended for early diagnosis in suspected cases. Frequent follow-up or orchiopexy should be performed to protect the contralateral testis, if necessary, in order to avoid anorchic situation in the future.

Infertility affects 1 in 6 couples and male factor infertility is the cause in 50% of cases. Azoospermia is defined as the absence of spermatozoa in the ejaculate and is considered the most extreme form of male factor infertility. In the past, these men were considered infertile, but with the advent of testicular sperm extraction and assisted reproductive technologies, men with azoospermia can biologically father their own children. Non-obstructive azoospermia (NOA) occurs when there is a defect in spermatogenesis. This review describes the contemporary management of NOA and discusses the role of hormone stimulation therapy, surgical and embryological factors, and new technologies such as proteomics, genomics and artificial intelligence systems in the diagnosis and treatment of men with NOA. We also emphasise that men with NOA represent a vulnerable population at high risk of developing cancer and cardiovascular comorbidities.

Published: March 2024

It is necessary to follow new strategies for the isolation of bacteria with unique characteristics from novel sources during the search for new antimicrobial compounds. Geobacillus thermoleovorans strain Ir1 (JQ912239), a novel thermophilic bacterium, which was isolated from soil in Iraq (Basrah and Baghdad)    showed a good ability to utilize hydrocarbon compounds. This study objective was to demonstrate G. thermoleovorans Ir1 potential antibacterial capabilities. The ability of the spore-forming bacterium G. thermoleovorans Ir1 to produce antimicrobial bioactive compounds that affects two pathogenic bacteria Pseudomonas aeruginosa and Staphylococcus aureus was investigated. The zones of inhibition were 16 mm and 15mm respectively. Extracted bioactive compounds were identified using gas chromatography-mass spectrometry (GC-MS) analysis. The results showed that this strain inhibited the growth of the tested bacteria. The antimicrobial activity of the strain might be due to the combination between formamide and 2, 2-bis-(4-hydroxyphenyl)-butane compounds as prodrugs by comparing the gas chromatography-mass spectrometry analysis of the pure and mixed extracts.. Moreover, the filtrate of the thermophilic G. thermoleovorans Ir1 was examined for inhibition of biofilms formed by pathogenic bacteria, the results showed that the filtrate was able to inhibit the biofilms of P. aeruginosa, S. aureus, B. subtillus, K.  pneumonia, and E.  coli.. The results of this study are the first to record the  the production of these bioactive substances by the thermophilic G. thermoleovorans Ir1 at 65°C.

Published: March 2024

Factor and cluster analysis, two multivariate statistical approaches, have been used to analyze temporal and spatial variations and pollutants sources effecting the water quality of Tigris River from the north to the south of Baghdad city. From October 2021 to September 2022, 15 water quality parameters (electrical conductivity (EC), pH, water temperature (WT), turbidity (Tur), total hardness (TH), biochemical Ooxygen Ddemand (BOD), dissolved oxygen (DO), Mg+, Ca+, SO4, dissolved solids (TDS), total suspended solids (TSS), total chlorine (TC), Cr, and Al) were tested at five monitoring sites (Balad, Al-Ghrai’at, Al-Shuhada'a Bridge, Al-Za’franiya, and Jisr Diyala), along the study area of the river. Results revealed that the major factor that affects the water quality in the study area is the anthropogenic factor. Spatial cluster analysis of the monitoring sites revealed three different groups that were compared to one another where each site suggested a different degree of contamination in the Tigris river water quality.

This study was carried out with the freshwater mussel Unio tigridis exposed to lead nitrate. The samples of water and mussels were collected from Qandil water resources situated in Qandil village at 36° 37' 39.55" north latitude and 44° 10' 51.80" east longitude, and it is  322 meters above sea level. In January 2022, rivers and aquariums water were tested for temperature,  pH, EC, TDS, DO, total alkalinity, total hardness, and calcium and magnesium ions. Studied organisms were exposed to variable concentrations of lead nitrate ranging from 0 to 900 ppm. The 96-h median lethal concentration (LC50) was measured and a comparison was made between the behavioural responses of the control and treatment groups. Also, the concentrations of lead in the experimental media, shell, and soft tissue of mussels were measured. A sample of mussels collected from aquarium was tested for biochemical markers, including acetylcholinesterase (AChE), Glutathione S-Transferase (GST), Catalase (CAT) and malondialdehyde (MDA). After 96 hours, the LC50 was estimated to be 782.7 ppm. The findings on behaviours revealed that lead slows down species' activities. Lead concentratiom increased within the mussel body as the water lead level decreased. The value of AChE was inversely related to lead concentration. However, GST, CAT and MDA increased with lead exposure.

Calocybe indica, commonly known as the milky white mushroom, is an edible mushroom native to India. The antigenotoxic potential of the aqueous basidiocarp extract (25 g/L and 50 g/L) of C. indica was investigated using the Allium cepa test system. Meristematic cells of root tips treated with 100% Coca-Cola served as a positive control. A significant reduction in the mitotic index (7.83 ± 0.60) was observed in the positive control (100% Coca-Cola) compared to the negative control. The highest percentage (65.25 ± 4.58) of chromosomal abnormalities was observed in the positive control. Chromosomal abnormalities were significantly reduced in root tip cells treated with Coca-Cola followed by treatment with basidiocarp extracts such as 25 g/L and 50 g/L (30.32 ± 4.44 and 14.20 ± 2.41, respectively). Coca-Cola induced chromosomal abnormalities were reduced by treatment with basidiocarp extracts, demonstrating the antimutagenic potential of C. indica. The present study indicates that the aqueous basidiocarp extracts of C. indica have anti-genotoxic effects. The clastogenic abnormalities caused by Coca-Cola are competently restored in the root meristem cells of A. cepa treated with the extract.
