We have developed an experimental apparatus and confirmed that vibration can be suppressed by applying a caster angle to a caster during high-speed traveling. Public transportation services are declining, especially in highly mountainous areas, causing a reduction in the range of activities and the quality of life. Therefore, micro-mobility is attracting attention. Micro-mobility refers to vehicles that are small and can seat about two people. By applying active-casters to these vehicles, it is expected to improve the range of activities by enabling omnidirectional movement and intuitive operation on narrow roads. The active-caster is effective in terms of durability and vibration reduction because it can move in all directions using normal tires. However, there is concern that the steering axis may oscillate from side to side at short intervals when moving at high speeds with normal tires. Therefore, in this study, we developed an experimental apparatus to verify traveling of the active-caster at high-speed. However, in this case, traveling verification was conducted on a passive caster as a preliminary experiment. As a result, vibration of the steering axis of the caster was confirmed, and it was also confirmed that the caster angle suppressed oscillate at high speed. © The Author(s), under exclusive license to springer Nature switzerland AG 2025.

An immobilized hydrogen-producing consortium investigated biohydrogen production from food waste using a combination of sodium alginate and cassava rhizome biochar. We investigated the effect of varying the biochar concentration from 0 to 3% and the size of immobilized cells from 1 to 7 mm. Immobilized cells were prepared using 50% (v/v) enriched hydrogen-producing consortium, 2% (w/v) sodium alginate, and 0 to 3% (w/v) cassava rhizome biochar. The optimal conditions for achieving the highest hydrogen production in the batch fermentation reactor were identified as a biochar concentration of 2% (w/v) and an immobilized cell size of 2 mm. The highest hydrogen yield, maximum hydrogen production rate, and lag time recorded were 0.69 mmol H2/g-COD, 0.02 mmol H2/g-COD.h, and 41.51 h, respectively. This research highlights the potential of cassava biochar technology for efficient biohydrogen production from food waste, contributing to renewable energy generation and sustainable waste management. © The Author(s), under exclusive licence to springer-Verlag GmbH Germany, part of springer Nature 2024.

The electric energy produced by photovoltaic systems is a function of several variables that present random behavior, such as solar irradiance, ambient temperature, wind speed, and relative humidity. several models describe the energy produced by these systems, which reflect the various factors that influence the generation and how significant these influences are. In this way, the present work aims to compare some panel temperature models and the electrical energy produced from a photovoltaic system located in the Midwest of Brazil. The applied methodology aims to evaluate the expected averages and standard deviations of the monthly synthetic series of generated energy to identify the main random variables that influence the electric generation. The results indicate the model that best describes the physical system concerning the randomness of the variables involved, the photovoltaic technology, the location, and the measurement period. © 2021, European Association for the Development of Renewable Energy, Environment and Power Quality (EA4EPQ).

solar water heating in homes of low-income families as Energy Efficiency Action enables energetic benefits from points of view of the consumer and the Brazilian electrical system, thereby reducing environmental impacts associated with generation, transmission and distribution of electricity. The purpose of the present study is to evaluate these gains through measurement and verification methodology adapted from the International Performance Measurement and Verification Protocol, from case studies involving Energy Efficiency Projects in the Goiás state, Brazil. This paper also presents the stochastic modelling for the generation of future scenarios of electricity saving resulted by these Energy Efficiency Projects. The model is developed by using the Geometric Brownian Motion stochastic process with Mean Reversion associated with the Monte Carlo simulation technique. Results show that the electricity saved from the replacement of electric showers by solar water heating systems in homes of low-income families has great potential to bring financial benefits to such families, and that the reduction in peak demand obtained from this Energy Efficiency Action is advantageous to the Brazilian electrical system. Results contemplate also the future scenarios of electricity saving and a sensitivity analysis in order to verify how values of some parameters influence on the results, once there is no historical data available for obtaining these values.

Tropical forests and woodlands are key components of the global carbon and water cycles. Yet, how climate change affects these biogeochemical cycles is poorly understood because of scarce long-term observations of tropical tree growth. The recent rise in tropical tree-ring studies may help to fill this gap, but a large-scale quantitative analysis of their potential in global change research is missing. We compiled a list of all tropical tree species known to form annual tree rings and built a network encompassing 492 tropical ring-width chronologies to evaluate the potential to generate insights on climate sensitivity of woody productivity and to build centuries-long reconstructions of climate variability. We assess chronology quality, length, and climatic representativeness and explore how these change along climatic gradients. Finally, we applied species-distribution modeling to identify regions with potential for tree-ring studies in ecological and climatic studies. The number of tropical chronologies has rapidly increased, with ∼400 added over the past two decades. Yet, tree-ring studies are biased towards high-elevation locations, with gaps in warmer and wetter climates, on the African continent, and for angiosperm species. The longest chronologies with strongest climate signals (i.e., synchronous growth variations among trees) are from cool regions. In wet regions, climate signals and precipitation sensitivity decrease. Most tropical regions harbor 5–15 (and up to 80) species with proven potential to generate chronologies. The potential for long climate reconstructions is particularly high in drier high elevation sites. Our findings support strategies to effectively expand tree-ring research in the tropics, by targeting specific species and regions. Tropical dendrochronology can importantly contribute to global change research by generating historical context of climate extremes, quantifying climate sensitivity of woody productivity and benchmarking vegetation

Material stocks in long-lived products require over half of the annual global resource extraction for their construction and maintenance, and lock in energy use through their technical and geospatial characteristics. A thorough understanding of material stocks is therefore essential to inform sustainable resource use strategies. However, despite substantial advances in material stock research in recent decades, their robust quantification remains challenging and bears considerable uncertainties. We assess the (dis)agreement of material stock estimates from 32 recent studies across global, national, and urban scales, and propose recommendations for future work. Overall, we observe medium to high divergences between studies estimating the same material stocks. For end-use categories that aggregate multiple material stocks (e.g., buildings), most global-level estimates show divergences within 140 %. At the national level, most estimates for the UsA diverge by <210 %, while those for China by <550 %. At the urban level, most estimates for Beijing fall within 90 %, and for Vienna, within 70 %. For low-income countries, non-residential buildings, and individual materials, the differences are often substantially higher, highlighting the need for an improved scientific basis for policy and planning. These disparities arise from differences in system boundaries, methodology, data sources, definitions, and lack of data to capture the diversity of material stock types. To robustly inform sustainable resource use strategies, the scientific community and practitioners should systematically assess and report sensitivity and uncertainty, and reduce the latter through transparent documentation, model intercomparisons, consensus and open-access databases, enhanced data collection, and comprehensive quantification of material stocks.

Background: This study presents a composite solid fuel upgrading strategy by blending torrefied spent coffee grounds (Ts) into waste starch (Ws) at the weight ratios of 0 wt%, 5 wt%, 20 wt%, and 35 wt%. When the blending ratio of Ts exceeds 35 wt%, Ts-Ws composite fuel fails to pelletize. Blending Ts in Ws contributes to the higher heating value (HHV) and carbon content. Methods: The Taguchi method is utilized to identify the optimal torrefaction conditions for HHV of Ts. The highest HHV of Ts at 300°C (300-TsCG) is 31.76 MJ∙kg−1, which is about 2.08 times that of Ws. The carbon content, HHV, ignition temperature, and combustion reactivity of 35%Ts-Ws composite fuel are 51.15 wt%, 21.06 MJ∙kg−1, 262°C, and 4.6 wt%∙min-1∙°C−1, respectively. Attenuated total reflectance spectrometer, contact angle, hygroscopicity, mildew observation, storability, and water activity of Ts-Ws composite fuel are analyzed, and the storability of Ts-Ws composite fuel is discussed. significant findings: Compared with 0%Ts-Ws, the HHV of 35% Ts-Ws increases 38%, while the carbon content increases by 34%. The mechanical strength of Ts-Ws decreases with the increase of Ts blending amount. The strategy of blending Ts and Ws can significantly reduce the generation of Ws and spent coffee grounds (sCGs) and upgrade the quality of composite solid fuel. Accordingly, Ts-Ws is a promising composite solid fuel that can approach sustainable production of biofuels without compromising commercial viability. © 2024 Taiwan Institute of Chemical Engineers
