Authors: Książek-Trela Paulina , Figura Damian , Węzka Dominika , Szpyrka Ewa 
Published: March 2024

Abstract
The study focused on the contribution of effective microorganisms (EM) and their consortia, used in commercial biological preparations and formulations for soil revitalization, to the degradation of a mixture of 13 polycyclic aromatic hydrocarbons (PAHs) commonly found in the soil environment. PAHs, diverse forms of which are present in the environment, never occur individually but always as a part of a chemical mixture. Therefore, the research presented in this article, focusing on the EM impact on the mixture of PAHs, reflects the conditions most similar to natural ones. On Day 35 of the experiment, PAH levels decreased by 75.5–95.5%. The highest PAHs degradation efficiency was achieved for fluorene, with a preparation containing eight bacteria strains from the Bacillus genus: B. coagulans, B. amyloliquefaciens, B. laterosporus, B. licheniformis, B. mucilaginosus, B. megaterium, B. polymyxa, and B. pumilus. All tested preparations containing bacterial consortia and a preparation with the yeast S. cerevisiae intensified the PAHs degradation more effectively than formulations including only the yeast Yarrowia lipolytica or a mixture of Debaryomyces hansenii and Bacillus. The designed and proposed research will contribute to the development of biotechnological methods – bioremediation by microorganisms that are safe for the human and environment health.

Assessment of potential resistance to moisture damage and fatigue cracks of asphalt mixture modified with ground granulated blast furnace slag
Authors: Jasim Enas N. , Joni Hasan H. 
Published: March 2024

Abstract
Fatigue and moisture damage have been recognized as the most prevalent problems on asphalt roads, necessitating large annual expenditures for road maintenance. Much industrial waste is added to bitumen paving to enhance its conventional quality while decreasing the negative impacts on the natural environment and increasing resistance to pavement distress. This research uses ground granulated blast furnace slag (GGBFS) to substitute conventional filler (Portland cement [PC]) in hot mix asphalt (HMA). To determine how the GGBFS affects the HMA's susceptibility to moisture and fatigue cracks, Marshall characteristics, tensile strength ratio (TSR), and index of retained strength (IRS) of the asphalt concrete were evaluated. HMA was prepared with different rates of GGBFS (0, 25, 50, 75, and 100%) instead of PC. The data support the usage of 50% GGBFS in asphalt pavements as a partial replacement of PC, which enhanced Marshal stability by 34.4%, reduced flow value by about 12.9%, and increased TSR and IRS by 11.1 and 14.54%, respectively. The fatigue resistance of the modified asphalt mix at the optimum rate was evaluated with the four-point bending beam test; the fatigue life (Nf) increased by 33.8% relative to the reference mixture. The results obtained from this research hold scientific value for researchers and method designers aiming to enhance the resistance of hot asphalt mixtures to moisture and cracking. Using waste materials as an alternative to PC contributes to cost reduction while mitigating the environmental damages associated with cement manufacturing. To summarize, this research highlights the significance of exploring sustainable options in the construction industry, emphasizing the importance of reducing costs, and minimizing environmental impacts.
Investigating seismic response in adjacent structures: A study on the impact of buildings’ orientation and distance considering soil–structure interaction
Authors: Abdulaziz Mohammed A. , Hamood Mohammed J. , Fattah Mohammed Y. , Aal-Azawee Thamir K. 
Published: March 2024

Abstract
Through the past few months, our world witnessed and is still suffering from several severe earthquakes in different places around the globe like Turkey, Syria, and Morocco. Therefore, the seismic activity domain grew the center of attention for researchers, engineers, and even regular people. The most significant topics in this field that must be taken into consideration are soil–structure interaction (SSI) and structure–soil–structure interaction (SSSI). The term SSI refers to the connection among structure, foundation, and soil while the term SSSI refers to the link among adjacent structures with the soil. Formerly, these subjects were not taken into account through the numerical and analytical methods utilized for the dynamic analysis of the seismic response of the structures (i.e., the effect of soil was ignored), and this matter led to disastrous costs that included loss of lives and properties. This article intends to offer an inclusive helpful knowledge of some significant factors that were not taken into consideration in the previous studies and can be utilized in the field of seismic analysis and design for minimizing the possible risks of earthquakes particularly the heavy ones by defining the SSSI behavior of adjacent structures due to these factors. To accomplish this goal, a sequence of seismic examinations via a shaking table system will be performed taking into consideration the impact of soil media. These tests will inspect the effect of the structure’s orientation and distance between them on the dynamic response of two close steel structures predicating on sand soil. The orientations selected here are of two types: the first one is parallel to direction of the earthquake wave and the second one is perpendicular to direction of the earthquake wave. Each orientation will contain three tests of three distances: close distance, medium distance, and far distance. Two novel small-scale multi-degrees of freedom steel models of three storeys are utilized in this study. Test results illustrated that the diversity of buildings orientation with distances has a significant effect on the SSSI behavior of the neighboring buildings. It is seen that the orientation perpendicular to the direction of the earthquake wave offered maximum impact on the dynamic responses at the far distance while the parallel orientation gave ultimate effect at the medium distance.

Published: March 2024

Abstract
Poly(3,4-ethylenedioxythiophene) (PEDOT) is introduced on the surface of a metal–organic framework material by solvothermal method to prepare nanorods (TE@Zn-MOFs) with both flame retardant and thermoelectric properties. Data from cone calorimeter and TG-IR show that TE@Zn-MOFs effectively improves the flame retardant and smoke suppression properties of epoxy-based coatings. At a high TE@Zn-MOFs content of 10 wt%, the coating oxygen index increased from 18.2% to 29.0%, the total smoke release decreased from 25.26 to 22.60 m2, and the V-0 level was achieved in vertical combustion classification. Moreover, PEDOT enables epoxy-based coatings to output a certain current value at different heating temperatures (50–200°C). This work demonstrates that MOFs with flexible and variable structures can serve as effective flame retardants for epoxy-based coatings and endow coatings with fire warning characteristics, providing a way to develop multifunctional coatings for different application scenarios.

Published: March 2024

Abstract
Highly stretchable thermochromic wrapped yarns, which employ elastane filament (EF) as core, stainless steel wire, and thermochromic polyester filament as the first and second winding, was prepared, and the effect of elastane draft upon yarn properties was investigated. It was found that the elastane draft played an essential role in determining the final yarn behavior, and the optimized elastane draft parameter was 2.5 using Technique for Order Preference by Similarity to Ideal Solution. It is a distinctive configuration of yarn’s constituents and the EF draft that are responsible for the exceptional stretchability of yarns, and it showed mechanical robustness following cyclic stretch. Importantly, the yarn exhibited rapid, durable, and reversible color conversion when subjected to cyclic voltage, cyclic abrasion, and alkali. Finally, a flower-shaped pattern was fabricated by embroidering yarn onto an elastic substrate as a proof-of-concept, and no obvious variation of color fidelity was observed during the stretch.

Published: March 2024

Abstract
The seismically active Ka-Ping Block within Xinjiang, China, represents a zone of potential earthquake hazards, and existing surface measurements cannot fully reflect the area’s sub-surface slip rates. To determine these slip rates and characterize the level of hazard that the study area may face in future years, using a cross-correlation of waveforms, we identified 432 repeat sequences along large faults (F1–F5) in the Ka-Ping Block between September 2009 and April 2022 and computed the annual slip rate for every sequence with the empirical relationship of the moment and the seismic magnitude. Spatial distribution images and temporal evolution characteristics of deep deformation in fault zones were constructed. We obtained five asperities in the Ka-Ping Block, the western portion of the PiQiang fault (F4) had a larger yearly slide rate than its eastern portion, and the southwest and eastern areas of the KEP station show an elevated risk of seismic activity within the next two years.

Abstract

Objectives
Various techniques of closure of surgical incisions have been described ranging from various suture materials, staples and tapes to adhesive compounds. Cyanoacrylate is an adhesive compound available for surgical incision closure. Although sutures have been the preferred universal choice for surgical incision closure, glue is gaining popularity in specific places like pediatric injuries, facial injuries, laparoscopic incision closure, etc. This study aimed to compare the results between the application of cyanoacrylate and conventional suturing.

Methods
In this randomized control study, patients were divided into two groups of 100 each. The surgical incisions were closed using cyanoacrylate glue in Group A patients and polyamide (EthilonTM 2-0) in Group B patients. Post-operative pain was assessed using Visual Analogue Scale on the first, third, and seventh day. The wounds were evaluated for complications on post-op days 1, 3, 7, and 30 using the ASEPSIS score. Cosmetic outcome was assessed at the end of first month using the Modified Hollander Cosmesis Scale.

Results
Post-operative pain was significantly less in the glue group on days 1, 3, and 7. Wound infection with dehiscence occurred in 4 cases (4 %) in Group A and one patient (1 %) in Group B, which was statistically insignificant. There was no significant difference in cosmetic outcomes in either Group.

Conclusions
Cyanoacrylate is a good alternative to sutures in skin closure of clean and clean-contaminated surgical wounds.

Published: March 2024

Abstract
In response to the limitations of the existing online learning system regarding the efficiency and accuracy of the question-and-answer (Q&A) teacher recommendation method, this research develops a Q&A teacher recommendation model utilizing a Graph Convolutional Neural Network. First, a time-sensitive online learning Q&A teacher recommendation model (A Time Sensitive Online Learning Q&A Teacher Recommendation Model; TSRM) is proposed to address the shortcomings that current recommendation methods ignore, i.e., the teacher’s ability to answer questions with time changes. Then, a TSRM based on Short and Long Term Interest for Answering Questions (LSTR) is proposed to address the problem that the current recommendation methods ignore, i.e., the types of questions of student users’ concerns can change. Finally, we combine the TSRM model and LSTR model to build an intelligent recommendation model for answering teachers. The conclusion is that the accuracy rate of TSRM model on the test set is 99.5%, and the recommendation success rate of LSTR model reaches 98.4%, which are better than the other two models. The above results can show that the LSTR model and TSRM model constructed by the study have high performance and can effectively perform the recommendation of answering teachers in the online learning system, thus improving the efficiency of solving students’ problem, improving students’ learning effect, and contributing to the development of university education informatization.
Momentum space separation of quantum path interferences between photons and surface plasmon polaritons in nonlinear photoemission microscopy

Published: March 2024

Abstract
Quantum path interferences occur whenever multiple equivalent and coherent transitions result in a common final state. Such interferences strongly modify the probability of a particle to be found in that final state, a key concept of quantum coherent control. When multiple nonlinear and energy-degenerate transitions occur in a system, the multitude of possible quantum path interferences is hard to disentangle experimentally. Here, we analyze quantum path interferences during the nonlinear emission of electrons from hybrid plasmonic and photonic fields using time-resolved photoemission electron microscopy. We experimentally distinguish quantum path interferences by exploiting the momentum difference between photons and plasmons and through balancing the relative contributions of their respective fields. Our work provides a fundamental understanding of the nonlinear photon–plasmon–electron interaction. Distinguishing emission processes in momentum space, as introduced here, could allow nano-optical quantum-correlations to be studied without destroying the quantum path interferences.
Prognostic value of a glycolysis and cholesterol synthesis related gene signature in osteosarcoma: implications for immune microenvironment and personalized treatment strategies
Authors: Feng Jinzhu , Zhang Jie , Chen Yong 
Published: March 2024

Abstract

Objectives
Osteosarcoma stands as a highly aggressive primary bone malignancy with a notable penchant for metastasis and a grim prognosis. The exploration of metabolic gene signatures, particularly those involved in glycolysis and cholesterol synthesis, has recently garnered attention for their potential to predict cancer progression and therapeutic outcomes. This study probes the prognostic value of a glycolysis and cholesterol synthesis-related gene signature (GCSRG) in osteosarcoma, along with its influence on the tumor immune microenvironment.

Methods
A comprehensive bioinformatics approach was applied to osteosarcoma samples from the TCGA database, incorporating unsupervised clustering to delineate patient subsets, differential gene expression analysis to identify key metabolic pathways, and survival analysis to ascertain prognostic validity.

Results
The investigation yielded a distinct GCSRG with significant prognostic capabilities. Notably, a high GCSRG score correlated with worse patient outcomes but revealed a marked enrichment in immune cell infiltration within the tumor milieu, suggesting a complex relationship between metabolism and immune surveillance in osteosarcoma.

Conclusion
The GCSRG emerges as a promising biomarker for osteosarcoma prognosis, offering new vistas for assessing patient suitability for immunotherapeutic interventions. The potential of the GCSRG to act as a guide for personalized treatment strategies is highlighted, underscoring the need for strategic therapeutic modulation based on metabolic and immune interactions to improve patient prognosis in osteosarcoma.

Published: March 2024

Abstract
Because of its narrow and aerodynamic design, cooling the trailing edge of a turbine blade offers an essential problem. For the trailing edge internal cooling of gas turbine blades, wedge-shaped channels are used. Pin-fin arrays play a critical role in enhancing heat transmission at the trailing edge of turbine blades. The flow and heat transfer properties of a number of wedge channels with staggered pin-fins of varied shapes are used to develop a design with a more effective heat transfer effect and reduced flow resistance. The present study compares the combination of circular pin fins and oblong pin fins in a wedge duct with a Reynolds number range of 12,000–85,000 and a constant heat flux (surface) of 3280 W/m2 applied to the bottom wall, top wall, and surfaces of the fins. The results indicate that the pressure loss is less in circular fins at the centre and oblong fins side by side, and it is 23.67 % less than circular and oblong fins in opposite positions. The Heat transfer coefficient for circular and oblong fins in opposite positions is 16.72 % higher than circular fins at centre and oblong fin side by side. The thermal performance factor is almost the same for both cases.

Published: March 2024

Abstract

Objective: This study was aimed at exploring the causal relationships of four sarcopenia-related traits (appendicular lean mass, usual walking pace, right hand grip strength, and levels of moderate to vigorous physical activity) with body mass index (BMI) and ovarian cancer risk, by using univariable and multivariable Mendelian randomization (MR) methods.

Materials and Methods: Univariable and multivariable MR was performed to estimate causal relationships among sarcopenia-related traits, BMI, and ovarian cancer risk, in aggregated genome-wide association study (GWAS) data from the UK Biobank. Genetic variants associated with each variable (P < 5 × 10−8) were identified as instrumental variables. Three methods—inverse variance weighted (IVW) analysis, weighted median analysis, and MR-Egger regression—were used.

Results: Univariable MR analyses revealed positive causal effects of high appendicular lean mass (P = 0.02) and high BMI (P = 0.001) on ovarian cancer occurrence. In contrast, a genetically predicted faster usual walking pace was associated with lower risk of ovarian cancer (P = 0.03). No evidence was found supporting roles of right hand grip strength and levels of moderate to vigorous physical activity in ovarian cancer development (P = 0.56 and P = 0.22, respectively). In multivariable MR analyses, the association between a genetically predicted faster usual walking pace and lower ovarian cancer risk remained significant (P = 0.047).

Conclusions: Our study highlights a role of slower usual walking pace in the development of ovarian cancer. Further studies are required to validate our findings and understand the underlying mechanisms.
УКРАЇНА ЯК ЗАРУЧНИЦЯ ДЕРЖАВИ
Authors: ХОМИН Петро 
Published: March 2024

Розглянуто причини затяжного відставання економіки України від тих країн, які не мають порівнянного з нею природного потенціалу. Зокрема, відзначено, що незалежно від періодів, умовно поділених на тоталітарний, волюнтаристський, стагнацію й «перебудову» з імітацією переходу до ринкової економіки включно, Україна ніяк не може позбутися статусу заручниці держави, тобто апарату політичної влади в суспільстві, який ніколи не допускав не те що кардинальних змін у економічній системі, але й будь-яких косметичних на кшталт косигінської реформи чи «перебудови».
Унаслідок приходу до влади демагогів, замість проведення виваженого реформування системи економічних відносин тривалий час відбувалося руйнування промисловості й аграрного сектору, катастрофічно знижувались обсяги випуску технічних засобів виробництва, виник критичний дисбаланс не тільки між рослинництвом і тваринництвом, але й усередині цих галузей. Отже, Україна, яка була флагманом серед країн Східної Європи, втратила свої лідерські позиції як у промисловості, так і в сільському господарстві. У свою чергу, Польща, економіку якої реформували освічені інтелектуали, з типової аграрної країни перетворилася на розвинуту промислово-аграрну державу.
За сучасної ситуації відбувається відплив за кордон з України найбільш продуктивних за віком працівників, у тому числі й кваліфікованих спеціалістів, а значна частка створеної їхньою працею продукції з доданою вартістю нерідко імпортується Україною, чим майже подвоює прибуток зарубіжних роботодавців за рахунок мігрантів і українських споживачів. І такий стан справ набув непереборних ознак, незважаючи на те, що з державного бюджету щороку виділялися мільярдні дотації на підтримку як видобувної промисловості (зокрема, вугільної), так і сільського господарства.
