Abstract 1 Introduction
With dwindling terrestrial energy resources, there's a societal consensus to harness clean, renewable energy. Submarine hydrothermal vents, hosting abundant and unexplored energy potentials, draw international academic scrutiny [1]. Yet, comprehensive research on exploiting their thermal energy systems remains sparse. Existing technologies persist with stability and efficiency challenges. While promising ventures in hydrothermal power generation exist, they grapple with heat loss, instability, limited capacity, and heightened damage susceptibility [2]. This study scrutinizes submarine hydrothermal vents, amalgamating terrestrial closed-loop geothermal technology to resolve challenges and enable efficient energy utilization [3]. Given the complex geology of these… More >

Abstract This study summarized a part of the research conducted by Kim et al. [1]. The utilization of low-lime calcium silicate cement presents a promising avenue for reducing CO2 emissions in construction fields. Ordinary Portland cement pastes with the type of calcium silicate cement powder were fabricated and solidified under carbonation curing conditions. The physicochemical characteristics of the pastes were examined via variable tests including initial setting and flow characteristics, compressive strength and so on. Limestone and silica fume were employed for the synthesis of the calcium silicate cement used here. The content of calcium silicate More >

Abstract This study focuses on the widespread utilization of environmental wind energy to power electronic devices and wireless network sensor nodes with low energy consumption characteristics. It explores the influence of relevant geometric parameters of wind-excited bluff body flexible electric cantilever structures on energy harvesting systems, aiming to enhance effective wind energy collection over a wider range of wind speeds. Through numerical analysis, considering the effects of flexible electric cantilever beam dimensions and rectangular cross-sectional bluff body dimensions on the critical flutter wind speed of the energy harvester, optimal structural parameters of the rectangular cross-sectional bluff… More >

Abstract 3D concrete printing (3DCP) has challenges in weak interlayer bond strength and steel reinforcement integration. Existing methods to improve the interlayer bond strength and integrate steel reinforcement have limitations in automatic operation and limited mechanical performance improvement. Strain hardening cementitious composites (SHCC), with the high tensile strength and tensile strain capacity, have the potential to achieve self-reinforced structures in 3DCP. Nevertheless, the wider adoption of SHCC in 3DCP is limited by the high cost of fibers and fiber agglomeration during printing.
To fill the gap, this study investigates the use of SHCC as bonding agent of… More >

Abstract Arthritis, caused by degeneration and wear of articular cartilage, affects millions of patients worldwide. It can result in chronic pain, swelling, stiffness, and significantly affect the mobility of patients. Hence, identifying a material as an artificial alternative to replace damaged cartilage is of great benefit. Hydrogel, because of its high water content and similarity with the extracellular matrix of cartilage, has been explored for potential use as artificial cartilage. In this investigation, Polyvinyl Alcohol-Polyethylene Oxide (PVA/PEG) hydrogel with similar mechanical properties to human articular cartilage (e.g. compressive modulus, stress-strain response) was fabricated using a freeze-thaw… More >

Abstract The 15-carbon terpenoid abscisic acid (ABA) acts in vascular plants as a versatile hormone playing essential roles in reproductive development, vegetative development and growth, stress-development interactions, and physiological responses to abiotic and biotic stresses. Over the past 60 years, ABA dynamics, regulation, and responses have been progressively characterized: synthesis, transport and translocation, conjugation and deconjugation, metabolism, sensing, signal transduction, and downstream responses. In this context, the discovery of ABA exporters and importers has added novel dimensions to the understanding of ABA regulation. Moreover, since the initial discovery of the adenosine triphosphate-binding cassette (ABC) AtABCG25 exporter… More >

Abstract The breeding process involves developing techniques to create cultivars that thrive in the ever-changing global climate, allowing for early harvesting and high yield. This study aimed to screen rice genotypes with early harvesting and high yield to develop new-generation cultivars. The study was conducted in a field experiment at the Department of Agronomy, Faculty of Agriculture, Universitas Gadjah Mada, Special Region of Yogyakarta, Indonesia, from December 2022 to April 2023. Ten genotypes were laid out using an Augmented Randomized Complete Block Design (ARCBD) with three rows and six columns. The observations were macro and micro-climate,… More >

Abstract Globally, salinity is a brutal environmental constraint that poses a major threat to agriculture worldwide, causing nutrient imbalances and oxidative stress, leading to reduced crop yields and quality. Date palm waste from the agro-industry is a major environmental problem, but its conversion to biochar for soil amendment could help alleviate the effects of salinity stress. Pepper is a commonly grown horticultural crop that is sensitive to salinity. That’s why the current experiment was conducted with the novel idea of exploring the potential use of biochar-based fertilizer derived from date palm waste as a mitigation strategy… More >

Abstract Tea, a globally cultivated crop renowned for its unique flavor profile and health-promoting properties, ranks among the most favored functional beverages worldwide. However, diseases severely jeopardize the production and quality of tea leaves, leading to significant economic losses. While early and accurate identification coupled with the removal of infected leaves can mitigate widespread infection, manual leaves removal remains time-consuming and expensive. Utilizing robots for pruning can significantly enhance efficiency and reduce costs. However, the accuracy of object detection directly impacts the overall efficiency of pruning robots. In complex tea plantation environments, complex image backgrounds, the… More >

Abstract Pineappleweed (Matricaria discoidea DC., Asteraceae) herb is an essential oil containing raw material with spasmolytic and anti-inflammatory activity. It is also rich in phenolics, which may be used in pharmaceutical practice. This study aimed to investigate the phenolic and amino acid composition and the hyporific and analgesic effects of the M. discoidea aqueous-ethanolic extract and its amino acid modifications. In addition, we developed a polyethylene oxide gel formulation with M. discoidea extracts for the 3D-printed oral solid dosage preparations. In M. discoidea extracts, 16 phenolic substances and 14 amino acids were established. The extract and its amino acid preparations More >
