Historical Depictions, Archaeological Practices, and the Construct of Cultural Heritage in Commercial Video Games: The Role of These Games in Raising Awareness
Authors: DaCosta Boaventura 
Published: August 2024

Abstract
Concerns regarding the historical accuracy, archaeological practices, and representation of cultural heritage (CH) in commercial video games (VGs) have fueled unending debates about their educational value. However, beyond offering interactive and engaging narratives, it is argued that these games play a vital role in CH. This work delves into the complexities inherent in representing history, archaeology, and CH within commercial VGs. It examines the portrayal of CH as a construct within these games, underscores the importance of collaborative efforts – between game developers, heritage professionals, and members of the communities represented – in their development, and highlights instances where commercial VGs can foster CH awareness. While many commercial VGs touch upon history and archaeology or embody diverse cultures as the platform for their narratives, the focus is placed on Shadow of the Tomb Raider to illustrate the many points found in this work because the game is said to ethically come close to representing the effects of archaeology on local populations and descendants of ancient people. The aim is to catalyze discussions among educators, researchers, game developers, heritage experts, and other stakeholders about the role of commercial VGs in enhancing learning and promoting consciousness about matters vital to cultural identities.

Abstract
As climate change and resource scarcity intensify, the need for energy efficiency, emissions reduction, and resource conservation grows. Forming technology offers significant potential for light weighting, cost and resource efficiency. However, current component design often neglects forming-related damage, such as voids, focusing primarily on mechanical properties and safety factors. Integrating knowledge of these voids into the design process can improve efficiency and increase light weighting potential. Advanced scanning electron methods, such as electron contrast channeling imaging, evaluated forming-induced damage and correlated it with fatigue properties. Crack initiation occurred mainly near manganese sulfide inclusions or near-surface voids, influencing crack propagation. Analyzing void distribution using advanced secondary electron methods enabled the development of a 3D volume model.

Abstract
When skin comes into direct contact with the outside environment, it becomes extremely prone to injury and external factors can make wounds difficult to heal. Traditional medical dressings often cause secondary injury and are poorly resistant to infection. Hydrogels offer a promising alternative to overcome these difficulties. In this study, chitosan (CS)/gelatin (GEL)/polyvinyl alcohol (PVA) hydrogels were developed by chemical cross-linking and loaded with the drug kitasamycin (KM) for testing. The hydrogels’ in vitro drug release and wound-healing properties were assessed. For 48 h, the drug release from the hydrogel in vitro persisted, which was significantly longer than the release time of the KM solution. Antimicrobial activity tests showed that the loaded KM hydrogel maintained its bacteriostatic ability at the same concentration as the KM solution, and during in vitro bacteriostatic inhibition, the duration of bacteriostatic inhibition of the KM hydrogel was significantly prolonged compared to that of the KM solution. This confirms the controlled release capability of the hydrogel. In addition, the hydrogel reduced the wound size in mice by 96 % and histopathological tests showed complete re-epithelialization of the wound. The prepared hydrogels successfully demonstrated their potential ability to control drug release and promote skin wound healing.
Gangsta-Rap als soziales Spiel
Authors: Bock Katharina 
Published: August 2024

ZusammenfassungDieser Beitrag bestimmt Gangsta-Rap als ein soziales Spiel, dem eine spezifische Sinnwelt zugrunde liegt – eine Welt, die von eigen(sinnig)en Sprach- und Verhaltensweisen sowie vielfältigen, zugleich bewussten und unbewussten Zielen und Bedürfnissen geprägt ist und dabei Wirkungen erzielt, die von den Spielenden teilweise selbst nicht überblickt werden. Dafür wird ethnographisches Datenmaterial präsentiert, das im Rahmen einer Studie mit jungen Szene-Insidern gewonnen wurde, die Gangsta-Rap nicht nur gerne hören, sondern diesen auch selbst produzieren. Im Rahmen eines ausführlichen ethnographischen Berichts, der die Wissensbestände, Bedeutungen und Regeln der Gangsta-Rap-Produktionen zugrundeliegenden Sinnwelt entfaltet, gibt der Beitrag detaillierte empirische Einblicke in Perspektiven, die in der sozialwissenschaftlichen Auseinandersetzung mit dem Genre und dessen Anhänger*innenschaft bislang zu kurz kommen.
High-Temperature Tensile Behavior of Structural Steel Grades with Varying Manganese Contents
Authors: Mohapatra J. N. , Dabbiru Satish Kumar , Balachandran G. 
Published: August 2024

Abstract
Three low-carbon (∼0.1 wt.% carbon) grades of structural steel with varying manganese content (0.75–1.5 wt.%) with ferrite-pearlite microstructure were used for the study. The 1.5 % manganese steel is a microalloyed steel with vanadium, niobium, and titanium content, which is strengthened by interphase precipitates. The steels were tensile tested at room temperature and in the temperature range between 200°C–700°C, at 100°C intervals. The elevated temperature flow strengths of the steels studied show higher strength values for the higher manganese steel. It was found that the manganese enhanced the strength at all ranges of test temperatures. The retention factor of the conventional structural steels was less than or equal to 0.50 against 0.66 for a fire-resistant steel grade. The study shows that the addition of elements such as chromium, molybdenum is required to achieve a higher retention factor to fulfill the requirement of fire resistance characteristics.

Published: August 2024

AbstractIn recent years, there has been a growing research interest focused on employing organosilicon compounds, including silsesquioxanes, as modifiers for different polymers. This work describes the methodology for obtaining a new nanocomposite using functionalized spherosilicates, which belong to the general group of silsesquioxane compounds. These modifiers are used as additives to polylactide to improve its properties in the context of the additive technology fused deposition modeling/fuse fabrication filament. The developed materials were characterized by better rheology compared to neat PLA. Differential scanning calorimetry analysis of the additives confirmed their reactive nature. Based on water contact angle tests, it was observed that up to 1.5% of the load, none of the additives influenced the wetting of the material surface. Microscopic images revealed visible agglomerations for the OSS-6MA-2TMOS system, while in samples with a lower share of methacrylic groups, very good dispersion of the additive in the matrix was observed. Also, the microscopic observations showed better melting of the composite layers containing additives in the 3D printing process, combined with the appropriate printing parameters, can ultimately produce more robust objects with fewer voids and discontinuities. The addition also resulted in an increase in mechanical parameters, mainly in terms of bending strength and impact strength.

Mechanical properties and fracture phenomena in 3D-printed helical cementitious architected materials under compression
Authors: Moini Reza , Rodriguez Fabian , Olek Jan , Youngblood Jeffrey P. , Zavattieri Pablo D. 
Published: August 2024

AbstractThe mechanical response and fracture behavior of two architected 3D-printed hardened cement paste (hcp) elements, ‘lamellar’ and ‘Bouligand’, were investigated under uniaxial compression. A lab-based X-ray microscope was used to characterize the post-fracture crack pattern. The mechanical properties and crack patterns were analyzed and compared to cast hcp. The role of materials architecture and 3D-printing-induced weak interfaces on the mechanical properties and fracture behavior are discussed. The pore architecture that inadvertently forms in the design of solid architected materials dictated the overall mechanical response and fracture behaviors in both 3D-printed architected materials. While no specific crack pattern or microcracking was observed in the cast element, lamellar architecture demonstrated a crack pattern following weak vertical interfaces. Bouligand architectures, on the other hand, exhibited a helical crack pattern with distributed interfacial microcracking aligned with the helical orientation of filaments. As a result, the bouligand architected elements showed a significant 40% increase in work-of-failure compared to cast counterparts. The enhanced energy absorption was obtained without sacrificing the strength and was attributed to higher fractured surface and microcracking, both of which follow the weak helical interfaces.
Screening for antibacterial activity of Cissampelos pareira L. root extract: an in-vitro study
Authors: Girma Abayeneh 
Published: August 2024

BackgroundThe recurrence of antibacterial infections after antibiotic treatment necessitates the investigation of alternative therapies against uropathogens. Cissampelos pareira is an Ethiopian medicinal plant that has been used for centuries by traditional healers to treat various diseases. The plant is selected on the basis of its traditional use in treating urinary tract infections by the local community. The objective of this study was to determine traditionally used anti-uropathogenic properties of C. pareira root extracts.
Methods C. pareira plant roots collected from Pawe Woreda were shade-dried, powdered, and extracted using chloroform, hexane, acetone, methanol, and ethanol, respectively. The antibacterial activities with different concentrations of the crude extracts were determined using the disc diffusion assay. The minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of the crude extracts were determined using a two-fold broth dilution method.
ResultsThe antibacterial activities of the root extracts against tested organisms as shown by inhibition zone diameters ranged from 7.0±0.1 to 20.8±1.0 mm. The highest inhibition was recorded from the ethanol extract while the lowest was from the chloroform extract. The MIC and MBC values ranged from 12.5 to 50 µg/mL and 25 to 100 µg/mL, respectively. Ethanolic and methanolic C. pareira root extracts showed the presence of antibacterial compounds (alkaloids, flavonoids, tannins, terpenoids and steroids).
ConclusionThis study showed that C. pareira root serves as a potential source for developing new antibacterial drugs against bacteriuria. However, nontoxicity evaluation is recommended for the use of herbals as therapeutic agents in pharmacy.
Radio Frequency Treatment of Sesame Oilseed for Quality Assessment

Published: August 2024

Background: Agricultural products are essential for human beings and maintaining their quality and storing them under optimal conditions is important. Sesame is a widely used cooking oil. Oil production and quality are important aspects of the food industry. However, during storage, the quality of sesame seeds can be greatly affected by factors such as moisture content, microbial growth and pests. Conventional techniques for eliminating pests and drying frequently entail the use of chemicals or high temperatures, which could cause health hazards and diminish the nutritional value of the seeds. However, dielectric measurement is a low-cost, rapid and effective technique for the detection and quality assessment of agricultural products. Methods: A specially designed coaxial sample holder was connected to an LCR Meter by using a computer-controlled interface. It operates on the principle of a cylindrical capacitor and is based on the cavity perturbation technique. The sample was contained in the cavity of a cylindrical sample holder and a specifically constructed temperature controller sensor assembly was used to regulate the temperature. Five different moisture concentrations of sesame oilseeds were prepared to study their dielectric permittivity, electrical conductivity and penetration depth over the frequency range of 100 Hz to 5 MHz. Result: This study indicates that the dielectric constant tends to change in a more regular and understandable manner as the frequency and moisture content vary, whereas the behaviour of the dielectric loss factor was less predictable and more irregular in response to the same changes. A linear regression model was developed to investigate the impact of the dielectric constant and loss on frequency and temperature. An R2 value of 0.705 indicates that the model is well explained, with 27.6% of the variance in temperature and frequency.
The Role of Sex and Gender in Transgender Bone and Other Musculoskeletal Health
Authors: Graves Leland , Lukert Barbara P. 
Published: August 2024

Abstract:
Musculoskeletal changes occur with gender-affirming hormonal therapy (GAHT) and gender-affirming surgery (GAS) used in the care of transgender adolescents and adults. Survey results have shown that orthopaedic surgeons desire to care for transgender individuals but express concern over a knowledge deficit. This article reviews the physiology and pathophysiology that may occur with GAHT and GAS. Transgender women have lower bone mineral density (BMD) prior to GAHT than cisgender men. Limited fracture data would suggest that transgender women >50 years of age have fracture rates similar to those of cisgender women. Transgender men have normal BMD prior to GAHT and are not at an increased risk for fracture compared with cisgender women. The use of puberty-blocking medications in the care of transgender youth does result in a decline in BMD, which returns to baseline with GAHT, but the effect of delaying puberty on maximal BMD and the lifetime fracture risk are unknown. At present, dual x-ray absorptiometry (DXA) is used to measure BMD and assess fracture risk. Attention should be paid to using the appropriate reference group in the interpretation of DXA for transgender individuals. Promote musculoskeletal health by ensuring appropriate calcium, vitamin D, weight-bearing activity, and a healthy lifestyle. Adherence to GAHT needs to be encouraged to avoid bone loss. Data with regard to therapy for osteoporosis in transgender patients have been lacking, but, at present, use of available therapies is expected to be effective. Information with regard to differences in other musculoskeletal health issues such as joint injuries has been lacking in transgender individuals.
Recognizing the Most Accurate Herschel-Bulkley Fluid Pressure Estimation Method for Annulus: An Update to API RP 13D, 7th Edition
Authors: Ashena Rahman 
Published: August 2024

Summary
The Herschel-Bulkley (HB) model is widely regarded as highly accurate for modeling non-Newtonian fluid flow, applicable across diverse fields such as chemical, mechanical, and petroleum engineering. The American Petroleum Institute and other references recognize the HB model as the most accurate and recommend the industry use it for drilling hydraulics. Pressure estimation models are beneficial for applying the HB model in field settings, as numerical solutions may not be feasible due to the computational demands and time constraints, especially challenging for high-frequency real-time pressure loss estimation (at least 1 Hz). Past literature has presented four estimation methods for the HB fluid, consisting of Zamora and Lord (1974), Merlo et al. (1995), Gjerstad and Time (2015), and the generalized method. However, the recommended practice API RP 13D (2023), “Rheology and Hydraulics of Oilwell Drilling Fluids,” has considered the most traditional Zamora and Lord (1974) as their chosen estimation method for industry use while neglecting to identify the most accurate model. Therefore, to update API RP 13D (2023), this work addresses this shortcoming by investigating the performance of different methods in estimating pressure losses while providing user-friendly, straightforward procedures applicable for field use.
To recognize the most accurate estimation method for industry use, different methods’ pressure losses were estimated and compared with the numerical solution as well as experimental data to find the errors. The results showed that the Merlo et al. (1995) method provides the most accurate estimates, with the least average absolute percent error (APE) of maximum 4% underestimating the numerical solution, followed by Zamora and Lord’s error overestimating the numerical solution. The errors may slightly vary depending on the input parameters used, including diameters, mud properties, and circulation rate. The effect of the circulation rate on the accuracy of different methods was also investigated; except for the generalized method, the accuracy of the other methods increases with increasing the circulation rate.
This work is a very innovative practical work for finding annular pressure losses accurately without using complex numerical solutions.
