Published: February 2025

Background

This study aims to utilize various nondestructive methods to assess the internal trunks of 3Acacia confusatrees affected byGanoderma australedecay.

Methods

Visual Tree Assessment (VTA) was employed to examine the trees, selecting 3 Taiwan acacia (Acacia confusa) trees at the base of whichG. australefungal fruiting bodies were growing, identified as severely damaged and classified as having an immediate hazard level. Subsequently, a stress wave device was used to detect the cross-sectional area of these trees at the locations whereG. australefungus was growing in order to obtain 2D tomographies of stress wave velocity. Following this, a resistance drilling instrument was used to examine the same cross-sectional areas, acquiring resistance drilling amplitude data. Finally, the 3 trees were felled, and 15-cm thick discs were cut from the same cross-sectional areas for laboratory testing.

Results

Using 2D sonic tomography and a corresponding velocity grid map of stress wave velocity revealed areas with varying velocities across the trunk cross sections. Drill resistance profile curves depicted changes in resistance strength, while visual inspections of disk cross sections indicated the location and severity of decay. Additionally, pilodyn penetration testing showed different penetration depths on the surfaces of the disk cross sections.

Conclusion

The study discusses the use of these detective methods to discover the location and extent of decay within tree trunks and assesses the percentage of decay in cross-sectional areas, providing a reference for tree risk assessment levels.

Authors:   Siddhartha Institute of Pharmacy, Dehradun, Uttarakhand, Singh Sanjay , Pandey I. P. ,   Professor Emeritus, Govt. of Uttarakhand
Published: February 2025

Generation of the reactive oxygen species (ROS) or intracellular abilities to elimination of ROS are out of balance, which leads to oxidative stress. It causes excessive damage to all biomolecules, including lipids, proteins, DNA, and RNA. The antioxidant activity of plants is caused by these phytochemicals, which interact with the antioxidants substances that prevents oxidation and oxidatives injury caused by free radical. As a result, it can potentially neutralize reactive oxygen species or free radicals. Capsicum Chinense, a member of the Solanaceae family, is a rumbustious, easily-growing species that is found from the Tezpur DefenseResearch Laboratory, in Indian state of Assam, that the king chilli is the hottest chilli worldwide. This species is utilized as hepatoprotective, antitumor, diuretic, anti-inflammatory, and bactericidal medicines due to its antioxidant activity. Numerous researches carried out in the last few years have shown that many types of chilli consist of phenolic chemicals, carotenoids, and capsaicinoids—all among which have been shown to have biological activity. In this study we identify the anti-oxidant impact of hydro-methanolic extract of leaves parts of Capsicum Chinense or to estimate the Anti-oxidant effects of hydro-methanolic extract and compare to it with Silymarin by DPPH Radical Scavenging Assay methods because there is no scientific data presented to the anti-oxidant activities of this plant. The current investigation also showed that Capsicum Chinense leaves portions contain a variety of secondary metabolites. These phytochemicals may be a significant source of pharmacological compounds, meaning that the plant species have enormous possibility for used in the treat for a range of chronic illnesses. The species' crude extract exhibits encouraging antioxidant potential as well, supportive the old-style uses of this plant with scientific evidence.

Current study revealed about the dyeing properties of Hibiscus acetosella on cotton fabrics using natural mordant. The plant Hibiscus acetosella, often known as African Rose mallow or Cranberry Hibiscus, is a member of the Malvaceae family. Hibiscus acetosella typically produces crimson or pinkish-red flowers. Dyes are extracted from Hibiscus acetosella flowers, producing a natural colorant. The dyeing pigments present in Hibiscus acetosella were extracted in this work by use of the aqueous extraction method, which required a 15-minute immersion in water and extracted dye was used to dyeing cotton fabrics without a natural mordant, and three fractions extracted were taken to observe the impact of three distinct mordanting techniques: pre, post, and simultaneous mordanting. The cotton cloth was soaked in a bath of boiling water with the coloring solution for five minutes. Following dyeing, the pH of the remaining sample was once more measured with a pH meter, and pH fluctuations were documented.

Regional anesthesia for rapid recovery after orthopedic surgery
Authors: Kim Min Kyoung , Kim Jin Sun , Kang Hyun
Published: February 2025

Background: Orthopedic surgery is becoming increasingly common, particularly among older adults, due to population aging and the rising incidence of degenerative conditions. Older patients frequently have multiple comorbidities, which elevate the risk of surgical complications. Effective pain management is crucial in facilitating recovery and reducing the likelihood of postoperative complications. This review examines the role of regional anesthesia in optimizing recovery outcomes for orthopedic patients.Current Concepts: Regional anesthesia significantly reduces opioid consumption, which in turn mitigates side effects such as nausea, vomiting, respiratory depression, and urinary retention. It also promotes early mobilization, which is crucial for functional recovery, and helps prevent complications such as deep vein thrombosis and muscle atrophy. Advanced techniques like local infiltration analgesia and motor-sparing blocks offer effective pain relief while preserving muscle strength. This not only facilitates faster rehabilitation but also reduces the length of hospital stays. These advantages underscore the importance of regional anesthesia in improving surgical outcomes and expediting recovery.Discussion and Conclusion: Regional anesthesia is crucial in improving recovery after orthopedic surgery by providing effective pain management, facilitating early mobilization, and minimizing complications. It is essential to customize the anesthetic approach based on the specific surgical procedure and the patient’s overall health to achieve optimal outcomes.
Multimodal analgesia strategies for optimized pain management in thoracic surgery
Authors: Hwang Wonjung
Published: February 2025

Background: Thoracic surgery often causes severe postoperative pain, even when minimally invasive techniques are employed. Effective pain management is essential for optimizing recovery and improving patients’ quality of life. Traditional opioid-based strategies effectively alleviate pain, but often lead to significant adverse effects. Multimodal analgesia (MMA) is a comprehensive approach combining pharmacologic and non-pharmacologic methods. This strategy aims to minimize opioid use, target multiple pain pathways, and improve recovery outcomes.Current Concepts: MMA covers the entire perioperative period and utilizes non-opioid agents such as acetaminophen, non-steroidal anti-inflammatory drugs, gabapentinoids, dexmedetomidine, lidocaine, and ketamine—used either individually or in combination. Regional anesthesia techniques, such as thoracic epidural anesthesia, paravertebral blocks, and fascial plane blocks (including erector spinae and serratus anterior plane blocks), have been shown to effectively reduce pain scores, opioid use, and complications. Enhanced recovery after surgery (ERAS) protocols support these multimodal strategies, highlighting the importance of regimens tailored to each patient’s characteristics and the specific surgical procedure. Integrating MMA into ERAS programs has been associated with enhanced recovery, reduced length of hospital stays, and improved quality of life.Discussion and Conclusion: MMA provides comprehensive pain control by targeting both nociceptive and neuropathic pain mechanisms, thereby reducing opioid-related side effects. Nevertheless, evidence gaps remain concerning the best therapeutic combinations and long-term outcomes. Large-scale clinical trials should be conducted to confirm the efficacy of advanced nerve blocks and tailored analgesic strategies. Evidence-based, patient-specific pain management protocols are needed to improve surgical outcomes, accelerate recovery, and enhance patient satisfaction in thoracic surgery.

Published: February 2025

The circular economy encourages optimizing use of plastics, waste reduction, sustainable materials, and processing of plastic products. In this framework, the use of agricultural waste materials promotes waste reduction and eco-design in plastic product manufacturing. This study researched the preparation of an isotatic polypropylene (PP) matrix (MFI 50 grade) with spent coffee grounds (SCG) and various commercial additives. The biocomposites were analyzed to evaluate their mechanical properties and processability. PP and SCG composites were synthesized with 30% SCG content with maleic anhydride grafted polypropylene (PP-g-MA), stearic acid and epoxidized oil as compatibilizers. The study found that polypropylene grafted with maleic anhydride (PP-g-MA) as a compatibilizer improves SCG dispersion, enhancing processing stability. Epoxidized oil (EO) and stearic acid (SA) can also function as lubricants that significantly improve composite processability by decreasing specific energy and shear viscosity. The processability properties were accessed using a torque rheometer. A tensile test showed that while SCG addition decreases mechanical strength, PP-g-MA improves interfacial adhesion, and EO and SA increase flexibility by reducing brittleness.
Impact of Glass Fiber Content and Packing Pressure on Weld Line Integrity in Injection Molded Short Glass Fibre Reinforced Polyamide
Authors: Mokarizadehhaghighishirazi Majid , Buffel Bart , Lomov Stepan V. , Desplentere Frederik
Published: February 2025

Managing the challenge of weld lines of short-fiber reinforced polymers (SFRPs) in injection molding is crucial for enhancing the mechanical performance of these composites. This study evaluates the impact of various glass fiber contents (0 to 50 wt%) within a polyamide 6 (PA6) matrix on the tensile and flexural properties at weld lines, comparing each sample to its counterpart without a weld line. Our findings indicate that weld lines have minimal impact on the mechanical properties of composites with low fiber content (10 wt%). However, at higher fiber contents, the strength, modulus, and strain at fracture are significantly reduced due to unfavorable fiber orientations at the weld lines. Increasing the packing pressure during injection molding can partially recover these properties by promoting favorable fiber orientation at the weld line. This signifies the importance of carefully controlling processing parameters to optimize the mechanical performance of SFRPs at weld lines.
Process transfer of PECVD gas barrier coatings between PE-HD and PP hollow bodies
Authors: Alizadeh Philipp , Oberle Kevin , Dahlmann Rainer
Published: February 2025

This study investigates the plasma enhanced chemical vapor deposition (PECVD) coating process transfer between PE and PP substrates. An inverse relationship is observed between the barrier improvement factor (BIF) and applied energy density (E), with PE showing a stronger response. The same process gas ratio optimizes both materials, suggesting geometry influences the barrier effect more than material. However, the barrier on PP is limited, indicating poorer compatibility to functionalization. The development of the intermediate layer did not improve the barrier performance. FESEM analyses and scratch tests suggest material damage during coating application. Further research is needed to optimize the coating process.

Published: February 2025

Welding technologies are state of the art for joining polymer composites, with one of the two joining parts considered laser transmissive (LT) and the other laser absorptive (LA). Pigments are often added to LT to enhance the crystallinity of the polymer matrix. However, pigments lead to internal scattering of the laser beam and the rate of transmission or the laser energy density decreases. Depending upon the type and amount of pigments added in the formulation of LT, the percentage of the laser beam transmitted, absorbed, or scattered differs. Laser welding performance depends on the laser energy available for welding after considering the losses. In the present study, optical transmission of injection molded isotactic polypropylene (iPP) samples were analyzed with a varying dosage of organic pigment (neat PP, 2%, 3%, 4%, 5%, 6%, 8%, and 10%) using a LPKF TMG 3 transmission tester. The device uses a wavelength of 980 nm and simulates the optical radiation conditions of diode laser transmission welding (LTW). The percentage transmission varied with the sample thickness and the composition percentage of pigment. The modified Bouguer-Lambert law described the transmission energy and apparent extinction coefficient. The model was validated with the experimental value of transmittances of the samples with varying sample thicknesses of iPP. There was a decrease in the percentage of laser transmission with an increase in the pigment content of the samples. It was found that the apparent extinction coefficient is a function of the pigment levels.

Published: February 2025

With growing environmental concerns about using conventional plastics in daily life, the demand for bio-based polymer products is increasing. Natural and biodegradable raw materials are alternatives for making plastic products more sustainable. Cellulose-based fibers have gained attention in preparing biodegradable polymer composites because of their biodegradable nature, bio-based origin, low cost and low weight compared to synthetic fibers (glass and carbon). In this research, hybrid fillers based on cellulose and hydrotalcite were used in biodegradable polymers such as in PLA and blend of PBAT/PLA to prepare bio composites. The loading of hybrid filler (cellulose/LDH) was done using a small-scale compounding machine. Hybrid fillers were used in compounding machines in different forms (paste, freeze dried, PLA dissolved, PEG mixed, and sheet based) with PBAT/PLA. The dosing method of hybrid filler in polymer was optimized in this work. Morphological analysis of hybrid filler and the mechanical properties of bio composites were also done. The tensile modulus of PLA was increased by about 33% when sheet-based hybrid filler was added to the PLA composite.
On the cryo-molding process and subsequent forming processes of biopolymers with low glass transition temperature
Authors: Petrausch Julius , Klein Daniel , Zimmer Johannes , Stommel Markus
Published: February 2025

Bio-based as well as biodegradable polymers are increasingly finding their way into applications such as food packaging. Here, certain biopolymers with a high degree of crystallinity may be of interest due to their superior barrier properties. Conversely, forming processes including high deformations often require an almost amorphous material state to avoid the brittle behavior associated with crystal structures. For some of those biopolymers, the narrow window in which they can be processed has delayed their potential use for packaging applications. In rigid packaging, two-step processes are commonly used for the production of containers from thermoplastic polymers. These processes, such as thermo forming or injection stretch blow molding, are a combination of a conversion step, e.g. film extrusion or injection molding, and a deformation step. However, to enable a forming process, the material properties after the first (conversion) step need to fulfil the mechanical requirements of the forming process. For semi crystalline polymers, these requirements are closely linked to the morphology of the converted material. A new process is presented to prevent crystallization and allow for a subsequent forming step. The efficiency of this process is evaluated on tailored lab scale equipment. This publication will provide insights into the opportunities as well as potential challenges presented by the “Cryo-Injection-Molding” (CIM) process. The CIM uses a mold that is cooled by liquid nitrogen. This mold is insulated and used in a lab scale injection process. This process is capable of cooling specimens down to their amorphous state (or semi-crystallin state with a very low degree of crystallinity) and allows the mechanical characterization in a softened state at a temperature above glass transition. To prevent unintended changes of the morphology, after the production process, the samples are stored at a temperature below glass transition and later heated using custom convectional heaters in a setup of a tensile testing machine. In this context, PBAT, PBS and PHA biopolymers are tested exemplarily.

Published: February 2025

Turning waste into high-quality products should be the aim of recycling, but it requires considerable effort to separate specific materials from others, clean them properly, and reconvert them into products. Such a process chain of mechanical recycling of post‑consumer polypropylene (PP) from a mixed waste collection was conducted with an advanced combination of state‑of‑the‑art technologies considering the material’s decontamination throughout the different process steps. The levels of solid and volatile contamination were analyzed with an optical control system and a gas chromatographic method, respectively, and were found to decrease in varying amounts throughout the process. The results of this study represent the currently achievable qualities of recycled PP in mechanical recycling and, based on these findings, the recycling process can be further improved.

PALACE v1.0: Paranal Airglow Line And Continuum Emission model
Authors: Noll Stefan , Schmidt Carsten , Hannawald Patrick , Kausch Wolfgang , Kimeswenger Stefan
Published: February 2025

Abstract. Below about 2.3 µm, the nighttime emission of the Earth's atmosphere is dominated by non-thermal radiation. Excluding aurorae, the emission is caused by chemical reaction chains which are driven by the daytime photolysis and photoionisation of constituents of the middle and upper atmosphere by hard ultraviolet photons from the Sun. As this airglow can even outshine scattered moonlight in the near-infrared regime, the understanding of the Earth's night-sky brightness requires good knowledge of the complex airglow emission spectrum and its variability. However, airglow modelling is very challenging as it would require atomic and molecular parameters, rate coefficients for chemical reactions, and knowledge of the complex dynamics at the emission heights with a level of detail that is difficult to achieve. In part, even the chemical reaction pathways remain unclear. Hence, the comprehensive characterisation of airglow emission requires large data sets of empirical data. For fixed locations, this can be best achieved by archived spectra of large astronomical telescopes with a wide wavelength coverage, high spectral resolving power, and good temporal sampling. Using 10 years of data from the X-shooter echelle spectrograph in the wavelength range from 0.3 to 2.5 µm and additional data from the Ultraviolet and Visual Echelle Spectrograph at the Very Large Telescope at Cerro Paranal in Chile, we have succeeded to build a comprehensive spectroscopic airglow model for this low-latitude site under consideration of theoretical data from the HITRAN database for molecules and from different sources for atoms. The Paranal Airglow Line And Continuum Emission (PALACE) model comprises 9 chemical species, 26,541 emission lines, and 3 unresolved continuum components. Moreover, there are climatologies of relative intensity, solar cycle effect, and residual variability with respect to local time and day of year for 23 variability classes. Spectra can be calculated with a stand-alone code for different conditions, also including optional atmospheric absorption and scattering. In comparison to the observed X-shooter spectra, PALACE shows convincing agreement and is significantly better than the previous, widely used airglow model for Cerro Paranal.
Storage potentials for carbon-rich products in Germany – a database and outlook on final storage of products derived from negative emission technologies
Authors: Diekmeier Sarah , Reiter Karsten , Henk Andreas , Friebe Colin
Published: February 2025

Abstract. Addressing the need to achieve the EU's net-zero emissions target by 2050, the inclusion of unconventional measures for CO2 removal from the atmosphere into the technology portfolio appears necessary, meaning the implementation of carbon dioxide removal (CDR) or negative emissions technologies (NET). Various CDR approaches are explored for their potential in carbon dioxide removal but do not take into account the final disposal of by-products and end products as well as the potential of different areas for the required long-term storage. To complement existing methods, the NETPEC project (Negative Emission Technologies based on Photo-Electro-Chemical methods) proposes a novel approach utilizing (photo-)electrochemical methods to convert CO2 into solid or fluid products for secure long-term storage. The aim of this work is to identify potentials for the final disposal of such carbon-rich products resulting from negative emission technologies and to develop a database of sites and areas in Germany, taking into account a broad regional distribution and sufficient storage capacities. Promising sites for storage are identified, highlighting the importance of comprehensive data collection and systematic evaluation. A database is established to catalog past, present and potential mining activity in Germany, providing essential information on storage potentials, regulatory considerations and potential estimations. Despite challenges in data availability and regulatory complexity, re-purposing old mining sites and mining related areas for storage offers significant potential in mitigating climate change by securely sequestering carbon-rich products. This study builds on the collection of data via the geological state offices towards the creation of a database on the determination of areas and estimations of potentials. The assessments suggest that even if only 1 % of these mining-related areas are considered suitable for storing carbon-rich products, a significant surface area of around 990 km2 – larger than Berlin – would be available. Additionally, another 348 km2 of subsurface space – surpassing the size of Frankfurt (Main) – could potentially be utilized. These figures highlight the immense storage potential of Germany's mining sites, making them key to the project's long-term carbon storage strategy. By utilizing existing infrastructure and geological formations, the project addresses the urgent demand for large-scale carbon storage while minimizing environmental impact and reducing costs. This database serves as a crucial foundation for informing, decision-making and ensuring effective implementation of carbon storage initiatives and shows possibilities for the subsequent use of such areas.
Physics-aware machine learning for glacier ice thickness estimation: a case study for Svalbard
Authors: Steidl Viola , Bamber Jonathan Louis , Zhu Xiao Xiang
Published: February 2025

Abstract. The ice thickness of the world's glaciers is mostly unmeasured, and physics-based models to reconstruct ice thickness cannot always deliver accurate estimates. In this study, we use deep learning paired with physical knowledge to generate ice thickness estimates for all glaciers of Spitsbergen, Barentsøya, and Edgeøya in Svalbard. We incorporate mass conservation and other physically derived conditions into a neural network to predict plausible ice thicknesses even for glaciers without any in situ ice thickness measurements. With a glacier-wise cross-validation scheme, we evaluate the performance of the physics-informed neural network. The results of these proof-of-concept experiments let us identify several challenges and opportunities that affect the model's performance in a real-world setting.

Education Doctorate in the Context of Generative Artificial Intelligence
Authors: Henriksen Danah , Mishra Punya , Woo Lauren , Oster Nicole
Published: February 2025

The emergence of generative artificial intelligence (GenAI) fundamentally shifts how educational knowledge is created, shared, and validated. Through the lens of epistemic technologies—tools that transform knowledge creation and dissemination—we analyze how GenAI challenges traditional notions of practical wisdom in education doctorate (EdD) programs. Drawing on parallels with previous epistemic shifts like written language, print, and digital media, we explore how GenAI, as a generative, dialogic, multimodal, and sometimes unpredictable technology, transforms practitioner knowledge and decision-making. We discuss implications for EdD programs, emphasizing the need to balance AI integration with the preservation of human judgment and ethical decision-making to maintain practical wisdom for scholarly practice.
Cofradía de los Negros de Huelva
Authors: Calvo Lázaro Rocío
Published: February 2025

Este artículo ofrece un acercamiento a la historia de la Cofradía de los Negros, que existió en Huelva desde, al menos, el siglo XVI hasta el primer tercio del siglo XX, siendo la única hermandad étnica de la ciudad. Para ello se han analizado las publicaciones existentes y, a continuación, se ha investigado en varios archivos de Huelva y Sevilla, atendiendo principalmente a las visitas pastorales realizadas a la vicaría de Huelva, donde se mencionaba a la hermandad. Por otro lado, a los testamentos, donde se han analizado las mandas religiosas, donaciones, limosnas y enterramientos de los testadores para averiguar los detalles de la cofradía. Se ha analizado además de sus fiestas, el patrimonio de la cofradía, así como el funcionamiento y organización de la misma.
Cabe destacar que la Virgen del Rosario fue una imagen muy devocional en Huelva, y posiblemente su cofradía fuese la más antigua de la ciudad.

Published: February 2025

La presente investigación analiza la imagen de un fotograma de la película The Belly of an Architect de Peter Greenaway a la luz de su interpretación de Étienne-Louis Boullée, centrando la atención en la complejidad inherente de la creación artística y la idea de la figura del arquitecto. De entre los diversos niveles posibles de lectura, esta investigación aborda los aspectos de la alegoría y personificación de los conceptos que representan la arquitectura boulleana a través del personaje principal, Stourley Kracklite, considerando que éste se contempla a sí mismo como heredero de Boullée, debido a lo cual se apropia del pensamiento, dibujos y proyectos de este arquitecto. El análisis hace visible la noción estética de Greenaway respecto al retrato abstracto de Boullée representado mediante la relación conceptual entre el proyecto boulleano del Cénotaphe à Newton, el tratado Architecture. Essai sur l’Art, los monumentos de la Antigüedad y la pintura del Renacimiento italiano, retomados en el fotograma de la película para establecer la identidad de Boullée y ofrecer una perspectiva de su arquitectura y sus fuentes.
A paisagem urbana da Rua 20 em Goiânia
Authors: Ribeiro Letícia Soares Martins , Mahler Christine Ramos
Published: February 2025

Esse artigo tem como proposta a discussão acerca dos conteúdos simbólico, histórico e arquitetônico da Rua 20 e dos processos recentes que os impactam com o objetivo de analisar algumas das transformações ocorridas em sua paisagem urbana original e os apagamentos dela decorrentes. A hipótese é que a recente oferta de locais a venda nessa rua – inclusive de edificações do período de construção da cidade, gera demolições, espaços não habitados e substituições, como os empreendimentos verticais e promove novas categorias na sua paisagem contemporânea, oriundas do desconhecimento de seus valores de origem e, principalmente, impulsionadas pela ausência de políticas voltadas para a manutenção e revitalização do centro histórico. Foram realizadas leituras de referências sobre o tema e sobre o objeto de análise, na perspectiva histórica e documental, além de estudos do espaço. O aporte da metodologia historiográfica foi aplicado para guiar a compreensão do estado da arte e construir as discussões pretendidas. Por fim, como contribuição, pretendeu-se demonstrar a importância da Rua 20 para a história de Goiânia e chamar a atenção para as transformações e apagamentos ocorridos no cenário dessa rua, como processos decorrentes das políticas de exploração do território.
