Additive Manufacturing with Polymer Composites for Sustainable Applications
Authors:   , Cummings Benjamin
Published: June 2024

The evolving field of digital manufacturing includes additive manufacturing (AM) that builds computationally sliced parts layer-by-layer. AM popularity continues to grow partially due to its potential to accelerate the transition to a circular economy. This thesis aims to help mitigate waste products using four novel polymer composites designed and developed for use with either fused filament fabrication (FFF) or direct writing (DW). These polymer composites are: 1) Simulation verified and AM printed triply periodic minimal surface lattice structures embedded with heat storage materials. Diamond TPMS geometry bentonite/CaCl2 embedded prints of low packed configuration adsorb <19.1% total dry cylinder weight and reaches 38.3 °C bulk temperature when stacked in an open reactor. 2) Microporous zeolite composites for carbon capture strengthened using novel sacrificial polymer content. Zeolite 13X composite UCS increases from 4.92 (±1.22) to 7.75 (±0.75) MPa with the addition of 4 wt% CSR providing a composite BET surface area of 148 (±17)cm3/g. 3) Printer filaments made from rPP hospital blue wrap previously destined for landfill or incineration. MFI is reduced from 103 (±8) to 45 (±2)g/10mins when increasing SEBS content from 9.1 wt% to 20 wt%. The reduced MFI facilitates filament extrusion and subsequent printing of tensile and impact samples with tensile strength and impact energy absorption up to 22.5 (±1.2) MPa and 14 (±0.8) kJ/m2, respectively. 4) Epoxy matrix composites for;i) weight saving applications and ii) bone-like composite manufacture to improve surgical training and patient communication. Drilled compression strength of bone-like epoxy matrix composites encompassed those of drilled bone compression strength, ranging between a 5 wt% gypsum and 20 wt%hydroxyapatite composite of 2.7 (±0.3) MPa to a 1 wt% PE, 40 wt% GY and 5wt% HA composite of 6.5 (±0.5) MPa. This thesis contributes a furthered understanding of low-cost desktop AM as utilised for local acquisition of custom engineering products that necessitates minimal lead times and transportation.

In this paper, we aimed to: 1) discuss the approaches for increasing the effectiveness of organ-preserving surgical treatment of uterine fibroids; 2) analyse pre-operative preparation options for the formation of a restitutive scar during myomectomy. The article addresses the epidemiology of uterine fibroids in women, particularly in the reproductive age, and discussed the role of inflammation, disrupted nutrition, and proteolysis in the development of myomatous nodules. We also consider the terminology, classification, primary clinical symptoms of uterine fibroids, and discuss the causes of uterine scar incompetence. Various growth factors and collagen types have a differential impact on myometrial and on the formation of a restitutive scar. Finally, we talk about the histological and immunohistochemical methods in the diagnosis of uterine scar incompetence.

Aim. Placental abruption is a severe complication of pregnancy, which is often accompanied by pre-eclampsia and early delivery. Here we aimed to study maternal and neonatal outcomes in patients with placental abruption depending on the severity of pre-eclampsia.

Materials and Methods. The study included 509 patients with placental abruption and pre-eclampsia from 22 medical centers in 16 regions of the Russian Federation, which were divided into two groups: patients with placental abruption and severe pre-eclampsia (n = 369) and patients with placental abruption and moderate pre-eclampsia (n = 140).

Results. Regardless of the severity of pre-eclampsia, average term of placental abruption was 34 weeks of pregnancy. Among the adverse maternal outcomes in patients with placental abruption and severe pre-eclampsia were coagulopathy (OR = 5.01; 95% CI = 1.17–21.46) and near miss proportion (OR = 2.95; 95% CI =1.22 –7.08) which were significantly more common as compared to a moderate pre-eclampsia. Neonatal outcomes were accompanied by a high perinatal mortality (12.8%) and neonatal morbidity due to a high prevalence of premature birth (65%), asphyxia (64%), and small for gestational age (40%). Groups with severe and moderate pre-eclampsia had no statistically significant differences in neonatal outcomes, excepting congenital malformations which were found less frequently (OR = 0.32; 95% CI 0.13–0.79) in severe pre-eclampsia.

Conclusion. Severity of pre-eclampsia did not affect neonatal outcomes in women with placental abruption. Maternal outcomes were significantly worse in patients with severe pre-eclampsia in comparison with those with moderate pre-eclampsia.

About 120 chemical compounds are registered in Russia as anticancer drugs, and screening and investigation of novel therapies remain an urgent task for specialists in pathophysiology, pharmacology and oncology. Among them, treatments targeting neovascularisation and regulated cell death of atypical cells within the malignant tumours are of utmost importance. Hence, development of novel anti-cancer drugs must include testing of their pro-apoptotic and anti-angiogenic activity. Here we review the markers of angiogenesis and regulated cell death during the tumor development and the respective immunohistochemical applications for preclinical trials. Here we discuss relevant molecular markers for studying primary cell death subroutines which can be targeted by anticancer agents. The most sensitive and specific immunohistochemical markers of programmed cell death are tumor necrosis factor alpha (TNF-α) for necrosis and anti-cellular apoptosis susceptibility/CSE1L, Bcl-2, and apoptotic protease activating factor-1 (APAF1) for apoptosis. Primary markers of angiogenesis include vascular endothelial growth factor A (VEGF-A), hypoxia-inducible factor 1-alpha (HIF-1α), and platelet-derived growth factor (PDGF). Analysis of tumour blood supply, metastasis and apoptosis has both theoretical and practical significance with direct implications for the pharmaceutical industry.

The Role of Worship Values in Enhancing the Efficiency of Islamic Commercial Banks: A Data Envelopment Analysis (DEA) Approach
Authors: Hidayat M. Fahmi , Aziz Roikhan M.
Published: June 2024

This study investigates the efficiency of Islamic banking in Indonesia from 2018 to 2021 through the application of Data Envelopment Analysis (DEA), incorporating Islamic principles. The analysis utilizes secondary financial data from four Islamic banks, sourced from the Financial Services Authority (OJK) and other researchers. The input variables considered include third-party funds allocated for profit-sharing and labor costs, while the output variables consist of revenue derived from the management of public funds and other operational income. The DEA results indicate fluctuating efficiency levels among the Islamic banks, with Bank Syariah Y consistently achieving 100% efficiency, signifying its status as the most efficient institution. The study identifies that revenue from public fund management negatively impacts the growth of Islamic banks, whereas labor costs and other operational income positively influence their development. These findings highlight areas requiring improvement and the factors driving efficiency in the development of Islamic banking in Indonesia.
Cowboy as a Symbol of Individualism: A Pragmatic Analysis of Red Dead Redemption 2
Authors: Haider Saied Karrar
Published: June 2024

As cultures are mainly divided into collectivistic and individualistic, members tend to emphasize, through communication, either their position as part of their group or their independence from the group. This emphasis is manifested in using the pragmatic concepts of positive politeness and negative politeness. The present study looks into the reflection of these two cultures in Rockstar’s renowned video game, Red Dead Redemption 2 (2018). It aims at identifying the two cultures as present in the game and showing their significance to its narrative. It fills the gap in the studies of language used within video games as well as its cultural reflections. The study addresses the following question: What are the positive and negative politeness strategies used in Red Dead Redemption 2 (2018), and what are the implications of using these strategies in its narrative? By adopting Brown and Levinson’s (1987) politeness theory, the researcher analyzed the positive and negative politeness used in the scripted dialogue of the in-game cutscenes through the mixed methods approach. The researcher hypothesized that the protagonist shows adherence to a collectivistic culture using positive politeness, and he begins transitioning towards an individualistic culture using negative politeness. The results showed that 75% of the protagonist’s interactions contained positive politeness while only 25% contained negative politeness. This transition explains the protagonist’s loss of trust and loyalty to his group as he begins to witness the futility of maintaining such loyalty. It also supports the overall narrative of the game as well as its cultural foundations.

Authors: Agrram Abdelaziz , Mokhtari Najat , Laaboudi Daouia
Published: June 2024

The present paper investigates the contribution of productive as well as receptive vocabulary breadths to Moroccan learners’ EFL speaking ability. The study’s significance lies in its exploration of the under-researched area of speaking proficiency, furthering our understanding of the link between vocabulary knowledge and language skills. To further probe this connection, particularly in the high school context, this study investigated the relationship between vocabulary size and speaking ability using valid and reliable vocabulary research instruments. This study addressed two research questions: a) to what extent do receptive and productive vocabulary size scores correlate with speaking ability? b) to what extent do receptive and productive vocabulary size scores explain the variance in learners’ speaking ability? To answer these questions, the researchers administered the Updated Vocabulary Levels Test, the Productive Vocabulary Levels Test, and a speaking task to 40 tenth-grade EFL participants. Spoken data were graded by reference to IELTS’ speaking band descriptors. Results of Pearson Correlation disclosed positive correlations between receptive and productive lexical breadths and speaking proficiency. Moreover, findings of multiple linear regression revealed that receptive and productive vocabulary sizes could explain performance in speaking ability. Implications for EFL vocabulary instruction and speaking proficiency development are discussed.
Multidimensional Analysis of Differences in Lexico-Grammatical Patterns in Saudi and British Linguistics and English Language Teaching Research Articles
Authors: Ali Sadia , Abdulhaleem Ebtesam
Published: June 2024

This study explores linguistic variation in research papers published by Saudi and British researchers in Linguistics and English language teaching (ELT). The main aim is to identify and compare interdisciplinary lexico-grammatical patterns between and within the sub-disciplines of these research articles, exploring the extent to which Saudi research articles align with or diverge from their British counterparts. Utilizing Biber’s (1988) multidimensional model, this research developed a specialized corpus of academic research articles, which was analyzed using multivariate statistical techniques to investigate linguistic variation. The corpus included tagging of 67 linguistic features, and factor analysis was employed to identify patterns of linguistic co-occurrence. Significant findings indicate that Saudi research papers distinctly differ from British papers in their preference for informational, explicit, non-argumentative, and abstract discourse. Notably, while most sections of the research papers showed variations in non-argumentative discourse, the ELT conclusion sections from both regions demonstrated a tendency towards mixed-purpose discourse. The significance of the study lies in its detailed analysis of how regional differences affect lexico-grammatical choices within academic writing, offering a deeper understanding of linguistic strategies in scholarly communication. The study concludes with recommendations for further research to explore underlying factors contributing to these differences and suggests the development of targeted academic writing aids to support researchers in achieving greater international coherence in their discourse. This could potentially enhance the clarity and impact of scholarly communication across diverse linguistic and cultural backgrounds.
Code-Switching in the Second Language Classroom: A Narrative Study of a Saudi English Language Teacher’s Experience
Authors: Alnefaie Amal , Gupta Abha
Published: June 2024

This narrative study explores the use of code-switching in the second-language classroom from the perspective of a Saudi English language instructor. The aim was to explore how the instructor experienced code-switching as a student and used it in her teaching. The main research question guiding the study was: How does a Saudi English language teacher perceive and utilize code-switching in her teaching practice, and how does this relate to her experiences as a language learner? The study holds significance in contributing to the ongoing discourse on code-switching in second-language classrooms, providing a nuanced understanding from the perspective of an individual who has experienced it as both a learner and a teacher. Examining code-switching from the viewpoint of a Saudi English instructor can offer valuable insights into teaching practices, student engagement, cognitive benefits, and sociolinguistic dynamics within the Saudi educational context, where Arabic is the dominant language and English is increasingly important. The study utilized a narrative inquiry approach involving a series of interviews. However, excessive reliance on code-switching may hinder language acquisition, and learners should gradually reduce their dependence on it as their proficiency improves. The study provided valuable insights into the lived experiences of second language learners and teachers, underscoring the need for further research using this methodology in the field of second language acquisition.

Authors: Jena Madhab Chandra , Mishra Sarat Kumar , Moharana Himanshu Sekhar
Published: June 2024

The gravure printing process is widely utilized for large-scale, high-quality, multi-colored printing tasks executed at high press speeds. This includes a diverse range of products such as art books, greeting cards, currency, stamps, wallpaper, magazines, and more. This thesis addresses the fire risks associated with gravure printing, acknowledging the use of highly flammable materials and the potential for static charge-related incidents. Despite its prevalence, there is limited research on fire prevention and control in gravure printing. The study employs field observations, stakeholder interviews, and an extensive review of literature on fire risk and control in printing press operations in India. It analyzes the causes of fires using the fire triangle model, emphasizing the role of heat, combustible materials, and oxygen in fire incidents within the printing press environment. The thesis categorizes preventive measures into fire prevention and fire suppression actions, focusing on reducing fire load, static charge mitigation, and implementing firefighting systems. It observes that poor housekeeping, lack of awareness, and inadequate emergency control plans contribute significantly to fire hazards in press facilities. Additionally, the research identifies key factors such as high press temperatures, low humidity, improper storage, and inadequacies in firefighting systems as potential causes of fires. It emphasizes the need for optimal environmental conditions, proper storage practices, and effective firefighting infrastructure within press facilities. The study concludes with comprehensive guidelines for loss prevention and control, including management programs, housekeeping, operator training, pre-emergency planning, preventive maintenance, and plant security. It also addresses safety measures specific to gravure printing presses, such as automatic sprinkler systems, fire hydrant system, carbon dioxide flooding systems, and portable fire extinguishers. In summary, this thesis provides valuable insights into the multifaceted nature of fire risks in gravure printing presses and recommends a holistic approach for effective fire prevention and control.
The narrative predictability of political ecology: Ethnographic refusals from the Ecuadorian Amazon
Authors: Vangsnes Gard Frækaland
Published: June 2024

Drawing upon critical social theory and fine-grained empirical observations, political ecologists have long argued against hegemonic stories of the environment, development and capitalism. This commitment is held across the wide range of approaches in political ecology. In a world haunted by increasing social inequalities and ecological degradations, there are strong reasons to pursue this critical agenda. In this article however, I coin the concept of "narrative predictability" to offer a critical analysis of a narrative tendency in political ecology towards a plot featuring the State and/or the Corporation as villains, the environment and indigenous peoples as victims, and activists as heroes. My engagement is not a reactionary attack, but rather an application of political ecology's main tool – empirical scrutiny – on itself. Empirically, the article draws upon recent fieldwork among indigenous Shuar people engaged in gold mining in the Ecuadorian Amazon. Theoretically, the article problematizes romanticism and essentialism within resistance studies. A key observation is that there seems to be a neglect of empirical complexity challenging the recurrent plot. What are the implications of avoiding discomforting observations when producing narratives aimed at progressive change? This article argues that political ecology needs to counter its own narrative predictability by strengthening its attentiveness to the heterogeneity and ambiguities of marginalized people in a world of capitalist ruins.

Published: June 2024

Congenital hepatic fibrosis (CHF) is a rare condition characterized by abnormal accumulation of fibrous tissue in the liver, leading to liver dysfunction. While CHF has been documented in various animal species, it has rarely been reported in cattle. This report presents a case of CHF in an aborted Holstein-Friesian fetus. During the necropsy, the most notable macroscopic findings included an enlarged liver with an irregular “cobblestone appearance” on the surface and firm parenchyma, as well as moderate ascites. Histopathological examination revealed extensive hepatic fibrosis in the portal areas, accompanied by bridging fibrosis extending between portal tracts and bile duct proliferation within the fibrous tissue. Screening for infectious agents as the cause of abortion or liver lesions was unremarkable. The necropsy and histopathological findings confirmed CHF, constituting the first case described in Holstein-Friesian calves in Serbia. Further research is required to determine whether this condition has a genetic basis or is influenced by yet to be identified factors in Holstein-Friesian cattle.

Published: June 2024

The present case report aims to describe a postmortem finding of a colloid goiter, without obvious clinical signs of endocrine disease in a 30-year-old American black bear (Ursus americanus) from the “Zoo” in the city of Sofia, Bulgaria. A clinical examination due to a bad general condition was performed under anesthesia and a computed tomography was conducted. After the established irreversible spondylarthrosis changes the bear was euthanized. Postmortem, the thyroid gland was pathologically examined and typical findings for a colloid goiter were observed. Hibernating mammals such as the American black bear have been shown to enter a state of physiological hypothyroidism during hibernation. Hormonal signals from the thyroid gland have been suggested to be a key mediator of hibernation. From the presented case could be assumed that the captive life conditions and the prolonged life of the zoo bears may affect the function of their thyroid gland.

Authors: Kabir Abdul , Ullah Kalim , Ali Kamboh Asghar , Abubakar Muhammad , Shafiq Muhammad , Wang Li
Published: June 2024

Foot-and-mouth disease virus (FMDV) is a highly contagious and economically devastating pathogen that affects cloven-hoofed animals worldwide. FMDV infection causes vesicular lesions in the mouth, feet, and mammary glands, as well as severe systemic symptoms such as fever, salivation, and lameness. The pathogenesis of FMDV infection involves complex interactions between the virus and the host immune system, which determine the outcome of the disease. FMDV has evolved several strategies to evade immune recognition and elimination, such as antigenic variation, receptor switching, immune suppression, and subversion of innate and adaptive responses. This review paper summarizes the current knowledge on the pathogenesis of FMDV infection and the mechanisms of immune evasion employed by the virus. It also discusses the challenges and opportunities for developing effective vaccines and therapeutics against this important animal disease.
Clinical and Psychological Factors Influencing the Perceived Stress among Patients with Anxiety and Depression in Remission during the COVID-19 Pandemic
Authors: Stoyanova V. , Kamenova I. , Vladimirova R.
Published: June 2024

Background and objectives

The COVID-19 pandemic has turned into a crisis with serious direct medical influence, and also with enormous indirect socio-psychological consequences. The study, which is part of a larger one, aimed to assess the perceived stress after the first COVID-19 wave in patients with depression and anxiety in remission and healthy controls and to evaluate clinical-psychological factors as predictors for moderate/high Perceived Stress (MH-PSS-10).

Methods

The study was cross-sectional, with 120 participants, grouped into four categories: anxiety in remission, depression in remission, healthy controls, and healthy first-degree relatives to patients with depression/anxiety. Self-assessment scales for depression and anxiety – Hospital Anxiety and Depression Scale (HADS), The UCLA Loneliness Scale – 3-point scale (UCLA-LS3), Perceived Stress Scale (PSS-10), and the State – Trait Anxiety Inventory (STAI-T, STAI-S) were used.

Results

The groups did not differ in the level of PSS-10. Using the ROC curve analysis, significant threshold values for HADS-A (≥ 6.50), HADS-D (≥ 2.50), STAI-T (≥ 38.5), STAI-S (≥ 39.5) (p < 0.001), and UCLA-LS3 (≥ 3.50) (p = 0.007) were determined. Using the multiple binary logistic analysis, depression (OR = 2.42), loneliness (OR = 2.36), STAI-S (OR = 6.55), and STAI-T (OR = 3.43) significantly increased the risk of MH-PSS-10.

Conclusion

Patients with complete remission of anxiety and depressive disorders did not differ from healthy controis in stress perception during the COVID-19 pandemic. Subthreshold values of depression, anxiety, and loneliness increased the feeling of moderate/high stress irrespective of the psychiatric history.

The objective of this study was to estimate the genetic parameters for age at first calving in Charolais and Limousine cattle breeds using animal model. The reproduction traits are influenced by genetic factors and environmental factors. The genetic factors are breed, individual and environmental factors are: climate condition and nutrition. The data consisted on 239 records for Charolais breed and 309 records for age at the first calving for Limousine breed. The data were from Romanian Breeding Association for Beef cattle. The age at the first calving was 792.92±6.77 days for Charolais breed and 813.83±6.09 days for Limousine breed. The heritability value for age at the first calving was 0.273 for Charolais and for Limousine breed was 0.275. The breeding values of cows with records for age at first calving were between −30.697 and 40.929 for Limousine breed were between −46.64 and 42.65. For improvement the reproduction traits it is necessary to improve the environmental conditions and supervision of reproduction activity in the farms and the selection of the best cows. The selection based on the breeding values of the cows determined the improvement of age at first calving. Improvement the reproduction traits increase the profitability of farms.

Authors: Şen Evren Hasan , Muruz Habip
Published: June 2024

This study was conducted to evaluate the effects of live Saccharomyces cerevisiae yeast (LY) supplementation on high-starch diets for dairy cows. Using a 2 × 2 factorial design, four treatment groups were examined: adequate starch without LY (AS-control), AS with LY (AS-LY), high starch without LY (HS-control), and HS with LY (HS-LY). LY was added at 2.9 × 106 CFU/200 mg DM or without yeast. In vitro gas and methane (CH4) production, organic matter (OM) digestibility, rumen fermentation, and metabolizable energy (ME) were analyzed. The Hohenheim Gas Test apparatus was used, and total gas volumes were measured at various incubation hours. Results showed no significant effects of LY or dietary starch ratio on gas kinetics, total gas, or CH4 production. Similarly, OM digestibility, fermentation kinetics, and ME were unaffected. In conclusion, LY supplementation did not alter in vitro gas, CH4 production, OM digestibility, rumen fermentation, or ME. Further research could investigate the underlying mechanisms, such as rumen microbial population influences.

Published: June 2024

This experiment aimed to investigate the effect of sea buckthorn meal alone and in combination with bilberry leaves on growth performance, health status and intestinal microflora in broiler chickens. A total of 90 healthy 1-day-old Cobb 500 broilers were randomly divided into 3 treatment groups and housed in digestibility cages under controlled environmental conditions. The dietary treatments included a basal diet (T0), a basal diet +1% sea buckthorn meal (T1) and a basal diet + 1% sea buckthorn meal and bilberry leaves (T2). The results showed that experimental diets did not influenced the growth performance. At 42 d, T2 had the highest serum iron level among the three groups. Compared to T0, T1 and T2 significantly reduced Enterobacteriaceae, E.coli and staphylococci in the cecal and intestinal contents and improved the lactobacilli populations number. The most effective way to reduce the number of harmful bacteria in the cecal content was through the diet that contained sea buckthorn meal alone. In conclusion, adding sea buckthorn meal in the diet of broiler chickens can be an effective solution to promote a healthy gut microflora. This aligns with the current strategy of reducing agro-industrial food waste by repurposing it in other industries.
Comparative Study of Digitalization Impact on Global Goods and Services Markets in Advanced and Developing Economies
Authors: Oliinyk Andrii
Published: June 2024

In the era of rapid technological progress, the influence of dizitalization on different aspects of international economic activity can’t be overstated. The aim of this article is to conduct a comprehensive comparative study of digitalization’s impact on global goods and services markets, with a specific focus on advanced and developing economies using multiple linear regression. The research methodology involved comprehensive data collection for 35-38 advanced economies and 52-66 developing economies depending on the availability of data. The analysis included depended variables (18 export and import goods sectors and 18 export and import services), independent variables (digitalization, consisting of ICT deployment, ICT export and import, ICT investment variables), control variables such as GDP growth, CPI, trade openness, exchange rate and political stability. The findings demonstrate the ICT infrastructure and ICT exports positive impact on export of technology-intensive goods, such as ores and metals, machinery and equipment, and tools and devices in advanced economies. Digitalization’s positive impact on trade in goods appeared weaker in developing economies, potentially due to lower levels of ICT adoption or differing export focuses. ICT export has positive impact on financial services imports, indicating a reliance on imported financial services while exporting ICT capabilities. The model shows a high success rate depending on variables. The study highlights digitalization’s varied impact on advanced and developing economies, emphasizing its importance for trade, competitiveness and policymakers in the global market.

This short review highlights the main sensor structures that are used in the ADAS (Advanced Driver Assisted System) field, in order to outline the progress at this moment (2023). Starting from this achieved level, we have proposed another approach to the ADAS problematics, regarding the prospects for development after the current moment, a different perspective than the one that has AV (Autonomus Vehicle) as its endpoint. Computer Assisted Driving represents a necessary and sufficient solution for increasing traffic safety in the near future. The integrated driver concept in the assisted environment implies a symbiotic human-machine collaboration. This collaboration requires a psychological acceptance of the ADAS system on behalf of humans, as an essential part of the current and future automobile. The progress highlighted by the documentation undertaken allows us to imagine a concept of a symbiotic human-machine system, based on the communication between ADAS and an external computing resource that assists the driver, based on the long analysis of recorded car events. Future automobiles must include an ADAS system that provides a subtle human-machine synapse, based on a series of computerized warnings to the driver generated in a timely manner, resulting from the high predictive capacity of AI-DLM algorithms. The computing speed of the local ADAS algorithms will be supplemented by the external server processing resource, accessed at the right time, to resolve an unexpected deadlock in the car roll.
