Aroma profile of two commercial truffle species from Yunnan and Sichuan, China: inter- and intraspecific variability and shared key compounds
No full textAroma is central to the worldwide success of truffles as gourmet food and the high prices paid for these edible mushrooms. In this study, volatile organic compounds (VOCs) from fruiting bodies of two Chinese truffles of commercial relevance, Tuber indicum and Tuber pseudohimalayense, were analyzed using headspace solid-phase microextraction (HS-SPME) coupled with gas chromatography-mass spectrometry (GC-MS). We aimed to characterize the aroma profile and determine whether it would be influenced by provenance and stage of maturation. We thus collected and analyzed young, middle mature and mature fruiting bodies of each species from different locations in Yunnan and Sichuan provinces, located in southwestern China. Overall, 76 VOCs were identified, belonging to different chemical classes, i.e. alcohols and phenols, aldehydes and ketones, benzenes and methoxy compounds, hydrocarbons and amines. A large number of volatiles identified in T. indicum and T. pseudohimalayense are reported here for the first time for these truffles. While more than 50% of identified VOCs were produced by both truffle species, considerable differences were present in the aroma profiles of fruiting bodies collected at various maturation stages, revealing a dynamic pattern in the biosynthesis of VOCs. Furthermore, truffles of different provenance had distinct proportions of volatile constituents, suggesting that, besides genetic factors, edaphic and microclimatic conditions influence the synthesis of VOCs in a complex manner
Chemo-Rheological Characterization of Aging Behaviors of Warm-Mix High-Viscosity Modified Asphalt
No full textToday, high-viscosity modified asphalt (HVMA) is widely used in drainage asphalt pavements. However, due to its high construction temperature, HVMA is prone to thermal oxidative aging, which reduces its life cycle and increases the maintenance costs of asphalt pavements. In this study, the effects of warm-mix additives on the physical, rheological and chemical properties of HVMA were studied to determine optimum warm-mix conditions. First, the effects of warm-mix technologies (foam warm mix, Sasobit, Evotherm, and GLWBR at 3%, 3%, 0.8%, and 0.8%, respectively) on the physical and rheological properties of HVMAwere studied. Then, two aging methods [thin film oven test (TFOT) and pressure aging vessel (PAV)] were applied to simulate the short-term and long-term thermal oxidation processes of HVMA and evaluate the influences of different warm-mix technologies on HVMA aging. The results showed that the four warm-mix technologies, especially foam warm mix and Sasobit, reduced the construction temperature of HVMA. In addition, warm-mix technologies also improved the high-temperature rheological properties of HVMA; however, they had adverse effects on the low-temperature cracking resistance of asphalt. Based on asphalt aging index fluctuations, it was evident that warm-mix technology was not conducive to the antiaging performance of HVMA, and foam warm mix had the weakest influence on the antiaging performance of high-viscosity asphalts. Furthermore, according to the results of an analysis of the carbonyl changes in aging asphalts, asphalt aging index can be applied to predicting the degree of aging of warm-mix HVMA.Green Open Access added to TU Delft Institutional Repository 'You share, we take care!' - Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Pavement Engineerin
Location-aware range-error correction for improved UWB localization
No full textIn this paper, we present a novel localization scheme, location-aware ranging correction (LARC), to correct ranging estimates from ultra wideband (UWB) signals. Existing solutions to calculate ranging corrections rely solely on channel information features (e.g., signal energy, maximum amplitude, estimated range). We propose to incorporate a preliminary location estimate into a localization chain, such that location-based features can be calculated as inputs to a range-error prediction model. This way, we can add information to range-only measurements without relying on additional hardware such as an inertial measurement unit (IMU). This improves performance and reduces overfitting behavior. We demonstrate our LARC method using an open-access measurement dataset with distances up to 20 m, using a simple regression model that can run purely on the CPU in real-time. The inclusion of the proposed features for range-error mitigation decreases the ranging error 90th percentile (P90) by 58% to 15 cm (compared to the uncorrected range error), for an unseen trajectory. The 2D localization P90 error is improved by 21% to 18 cm. We show the robustness of our approach by comparing results to a changed environment, where metallic objects have been moved around the room. In this modified environment, we obtain a 56% better P90 ranging performance of 16 cm. The 2D localization P90 error improves as much as for the unchanged environment, by 17% to 18 cm, showing the robustness of our method. This method evolved from the first-ranking solution of the 2021 and 2022 International Conference on Indoor Position and Indoor Navigation (IPIN) Competition
Rheological Properties of High-Viscosity Modified Asphalt Containing Warm-Mix Additives
No full textHigh-viscosity modified asphalt (HVMA) is the most commonly applied method in drainage asphalt pavements. However, some disadvantages of hot-mix HVMA, including high energy consumption and unavoidable environmental pollution, should be improved. Therefore, warm-mix additive (WMA) was introduced. In this paper, the effects of WMA on the rheological and microstructural properties of HVMA were studied to select optimum WMA conditions. WMAs mainly include foam warm mix (1%, 3%, and 5%), Sasobit (1%, 3%, and 5%), Evotherm (0.4%, 0.8%, and 1.2%), and the newly introduced warm additive glow brand (GLWBR) (0.4%, 0.8%, and 1.2%). Dynamic shear rheometer (DSR) and bending beam rheometer (BBR) tests were performed on HVMA after rheological processes. Also, microstructural properties were examined by Fourier transform infrared spectroscopy and scanning electron microscopy methods. Based on the obtained results, all WMAs reduced the viscosity (135°C) of HVMA and achieved warm mixing effects. However, absolute viscosity (60°C) was enhanced by Sasobit and GLWBR. In addition, GLWBR improved high-temperature rheological performance and had no significant effect on the low-temperature and aging performance of HVMA. These findings were further verified by morphological observations.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Pavement Engineerin

Aedeagus robust, tubular with a strongly sclerotized hook subapically; vesica tubular with strongly sclerotized cornuti apical-laterally. Diagnosis. Superficially, the new species is similar to S. fortis Yazaki, 1988, from which it can be separated by the smaller size (alar expanse 51–56 mm (n = 6) in S. hainana sp. nov., alar expanse 55–64 mm (n = 4) in S. fortis), the ground color of the body and wings (yellowish brown in S. hainana sp. nov., pale chestnut brown to brownish orange in S. fortis), the postmedial line of the forewing (white with dark brown to dark grey edges in S. hainana sp. nov., grey with black edges in S. fortis), and the medial fascia of the hindwing (distinctly dentate, distal edge with a large black shade medially, subterminal line with a indistinctly dark grey shade between M 1 and CuA 2 in S. hainana sp. nov., slightly waved, outer edge without a black shade distally, subterminal line with a distinctly black shade between M 1 and CuA 2 in S. fortis). In addition, these two species have some conspicuous differences in the male genitalia characters (In S. hainana sp. nov. uncus is relatively broad and short, with blunt apex, while it is slender, with pointed apex in S. fortis; gnathos is broad and tongue-shaped, with many small dentate processes on the ventral side, and with blunt apex in S. hainana sp. nov., whereas it is narrow and hook-like, with pointed apex in S. fortis; in S. hainana sp. nov. costal margins of the valvae have symmetrical hook-like processes distally, while in S. fortis costal margin of the left valva has a knife-like process and costal margin of the right valva has a finger-like process; valva with two distinct lobes medially in S. hainana sp. nov., but with only one dentate lobe in S. fortis; in S. hainana sp. nov. the hook-like process of phallus is relatively longer and bigger than that of S. fortis, and in S. hainana sp. nov. cornuti are longer than those of S. fortis). The new species also resembles S. flavicans Yazaki, 1988 but can be distinguished based on the ground color of the wings and body (only yellow brown in S. hainana sp. nov., dark pink or ochreous in S. flavicans), the forewing (less dots and stripes, costa with a white patch before apex in S. flavicans), the medial fascia of the hindwing (strongly dentate in S. hainana sp. nov., while slightly dentate in S. flavicans), and the male genitalia characters (uncus with blunt apex in S. hainana sp. nov., while it is very pointed in S. flavicans; in S. hainana sp. nov. gnathos tongue-shaped, while it is dentate in S. flavicans; each costal margin of valva distally with a finger-shaped process in S. hainana sp. nov., while with only a small dentate process in S. flavicans; valva with two lobes medially in S. hainana sp. nov. but much smaller and indistinct in S. flavicans).

No full textThe magnitudes of multi-physics effects on geothermal reservoir characteristics during the production of enhanced geothermal system
No full textThe multi-physics coupling process during the heat extraction from enhanced geothermal system, encompassing thermo(T)-hydro(H)-mechanical(M)-chemical(C) interactions, plays a pivotal role in changing geothermal reservoir characteristics. However, a comprehensive quantitative assessment of these multi-physics behaviors has been lacking. In this study, a novel approach was proposed to calculate the magnitude of mechanical, chemical, strong mechanical-chemical coupling, and weak mechanical-chemical coupling effects on the variations of reservoir characteristics. In particular, mechanical-chemical coupling effects are quantified for the first time. They are obtained by the fracture aperture difference results across five distinct coupling models (thermo-hydro, thermo-hydro-chemical, thermo-hydro-mechanical, partially-coupled four-field, and fully-coupled four-field models). The findings indicate that mechanical effects lead to an increase in fracture aperture, while chemical effects contribute to its reduction under underbalanced injection conditions. Strong mechanical-chemical coupling effects, exhibiting a negative correlation with chemical effects, conversely result in a diminished fracture aperture. The influences of these effects are investigated from the temporal and spatial perspectives. Temporally, mechanical effects dominate early production while chemical effects become prominent in later stages. Spatially, there mainly exists two zones when stable production: a mechanical-controlled region surrounding injection wells, and a chemical-controlled area distant from the injection wells. Furthermore, sensitivity analysis of injection concentration indicates its alternation changes the reservoir traits and production performance by modifying the magnitudes of chemical and mechanical-chemical coupling effects. This quantification of multi-physics effects offers insights into optimizing injection strategies for better geothermal development. The approach could hold promising potential in other geo-energy scenarios like carbon and hydrogen storage in reservoirs.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Applied Geolog
