Given the shortcomings of traditional heritage preservation practices in understanding the values that justify heritage protection, it is necessary to critically re-evaluate these practices adopted to physically protect the cultural asset, which rarely include the local values ascribed by the surrounding communities. This reflection motivated the development of this study that aims to examine the social valuation ascribed to protected railway assets on the route Jundiai-Campinas (Brazil), in order to compare the different identified values and reflect on the integrated actions of railway heritage preservation and management. To this end, a values-based approach (VBA) was used, a methodology employed for and centred on heritage preservation, which focuses on understanding the local community as one of the protagonists in the heritage valuation process. Applying the different techniques of the VBA method revealed that other values, besides the traditional ones dominant in the specialised dissemination of the subject, also have an impact on the heritage asset. By integrating these community values to the protection and management practices of the cultural asset, it is indeed possible to significantly protect and safeguard not only the monumental object but also its values.

The development of cost-effective technologies for treating and disinfecting wastewater to a level that makes it economically valuable, environmentally sustainable, and health-safe for reuse is of utmost importance. In this study, a direct descending filtration pilot unit was designed, assembled, and tested within a municipal wastewater treatment plant to produce nonpotable reclaimed wastewater. Bench-scale tests were performed to define the optimum coagulant type and dosage (Poly aluminium chloride, 15 mg L-1). The pilot plant performed best at a filtration rate of 15 m h-1 in a bed of commercial building silica sand with an average particle size of 0.93 mm, resulting in a net production of 0.103 m3 h-1 of treated water. The removal efficiencies for apparent color, E. coli, turbidity and total suspended solids were 86.8 +/- 2.3%, 86.8 +/- 3.6%, 76.9 +/- 6.9% and 68.7%, respectively. After a final stage of chlorine disinfection, the E. coli removal was higher than 99.7%. All the resulting parameters were within the recommended standards for nonpotable uses, such as landscape irrigation, dust and fire control, soil compaction, and street cleaning.

IEEE Symposium on Position Location and Navigation (PLANS)

This paper examines the safety of LiDAR-based navigation for driverless vehicles and aims to reduce the risk of extracting information from undesired obstacles. We define the faults of a LiDAR navigation system, derive the integrity risk equation, and suggest landmark environments to reduce the risk of fault-free position error and data association faults. We also present a method to quantify feature extraction risk using reflective tape on desired landmarks to enhance the intensity of returned signals. The high-intensity returns are used in feature extraction decisions between obstacles and pre-defined landmarks using the Neyman-Pearson Lemma. Our experiments demonstrate that the probability of incorrect extraction is below 10 −14 , and the method is sufficient to ensure safety.

In this research, we developed a biochar-based fertilizer using biogas slurry and biochar derived from lignocellulosic agro-residues. Biogas slurry was obtained through the anaerobic digestion of the organic fraction of municipal solid waste (fresh vegetable biomass and/or prepared food), while biochars were derived from residues from quinoa, maize, rice, and sugarcane. The biochar-based fertilizers were prepared using an impregnation process, where the biogas slurry was mixed with each of the raw biochars. Subsequently, we characterized the N, P and K concentrations of the obtained biochar-based fertilizers. Additionally, we analyzed their surface properties using SEM/EDS and FTIR and conducted a slow-release test on these biochar-based fertilizers to assess their capability to gradually release nutrients. Lastly, a bioassay using cucumber plants was conducted to determine the N, P, and K bioavailability. Our findings revealed a significant correlation (r > 0.67) between the atomic O/C ratio, H/C ratio, cation exchange capacity, surface area, and the base cations concentration with N, P, and/or K adsorption on biochar. These properties, in turn, were linked to the capability of the biochar-based fertilizer to release nutrients in a controlled manner. The biochar-based fertilizer derived from corn residues showed <15 % release of N, P and K at 24 h. Utilization of these biochar-based fertilizers had a positive impact on the mineral nutrition of cucumber plants, resulting in an average increase of 61 % in N, 32 % in P, and 19 % in K concentrations. Our results underscore the potential of biochar-based fertilizers in controlled nutrient release and enhanced plant nutrition. Integration of biochar and biogas slurry offers a promising and sustainable approach for NPK recovery and fertilizer production in agriculture. This study presents an innovative and sustainable approach combining the use of biochar for NPK recovery from biogas slurry and its use as a biochar-based

URBAN RESEARCH & PRACTICE 2023年第4期16卷 582-604页

作者： Hong, Nami Kim, Saehoon Seoul Natl Univ Interdisciplinary Program Urban Design Seoul South Korea Seoul Natl Univ Grad Sch Environm Studies Dept Landscape Architecture Urban Design Concentrat Seoul South Korea Seoul Natl Univ Environm Planning Inst Seoul South Korea Seoul Natl Univ Integrated Major Smart City Global Convergence Seoul South Korea

This study explored Vietnam's urbanization process and spatial restructuring over the last 30 years to conceptualize a new phenomenon challenging the concept of desakota. We constructed socioeconomic and urban land cover data from 1987 to 2018. Furthermore, we compared the urbanization process with the economic transition and mapped urban land growth patterns. The study found the following urbanization features: (1) fluctuating process of urbanization by development stage in a transitional economy, (2) formation of heterogeneous spatial patterns in metropolitan regions, (3) dramatic landscape changes caused by capitalistic property developments, and (4) functional reordering among urban centers and newly urbanized areas.

Software-based mold flow analysis is often performed to confirm optimized resin pipe arrangements. In this study, the GeoDict software and reverse scanning were employed to develop a method for performing rapid porosity and permeability estimation. A comparison of the results from one-dimensional resin flow and Easyperm tests revealed a 10% variation in the porosity and permeability parameters obtained through the proposed rapid estimation method. In addition, the obtained parameters were substituted into a Moldex3D model to simulate the resin flow on the personal watercraft hull during vacuum-assisted resin transfer molding (VARTM). A comparison of simulation results and hull infusion results revealed that the integration of the proposed rapid estimation method with Moldex3D allowed for the accurate simulation of the resin flow in large fiber-reinforced-plastic (FRP) products (variation <8%). The proposed method can be applied to large wind turbine FRP parts and large FRP yacht components to increase process planning efficiency and product stability.

Many factors, including regulations, community values, and economic and environmental considerations, influence environmental planning decisions. Across the nation, local elected and appointed boards and commissions are responsible for planning and land use regulations. However, few studies have focused on environmental planning through comprehensive and parks and recreation plans. Using Indiana communities as a case study, this research highlights the theory and practice of environmental planning and community development, emphasizing the importance of collaboration and the presence of social capital. Statewide focus groups found that communities integrate varying environmental planning processes into comprehensive and parks and recreation plans. As a result, these plans represent underutilized potential to guide conservation and collaboration. Integrating environmental planning into local government activities is limited by time, political will, and community awareness. As such, communities need continued support and resources to build social capital that leads to engaging with the public, decision-makers, and collaborators in meaningful ways to foster effective environmental planning.

In the mid-2010s, China initiated a quality-oriented urbanization model aimed at overcoming the urban crises resulting from the past quantity-oriented urbanization. The Xiong'an New Area (XNA), China's latest national-level new area, has been planned such that it serves as a showcase of the quality-oriented urbanization model. Based on a review of the official urban planning documents, this paper examines the characteristics of the XNA's urban planning and finds that the urban planning has integrated environmental friendliness, social inclusion, innovation-driven economy, cultural inheritance, and smart urban governance to facilitate the XNA's pursuit of quality-oriented urbanization. Besides analyzing its improvement over the previous urban planning, this paper also examines the XNA's challenges in its urban planning implementation. Although the XNA is subject to circumstances that make it unique, its urban planning can serve as a point of reference for attempts to urbanize among the world's other cities. This paper contributes to a more thorough understanding of the role of urban planning in promoting the transformation from quantity-oriented to quality-oriented urbanization models in the Chinese context.

Resolving the Theoretically Irreconcilable: Aldo Rossi's Giant Kitchenware Models as Generative Object--Subjects

引用

ARCHITECTURAL THEORY REVIEW 2020年第3期24卷 293-306页

作者： Chen, Dijia Univ Virginia Constructed Environm Program Sch Architecture Charlottesville VA 22903 USA

This essay investigates Aldo Rossi's coffee vessel models as exhibited in his "Domestic Theater" project as a mediator between conflicting ideas in his architectural and urban theory. Entangled with Rossi's paintings, kitchenware designs, and architectural projects, the coffee vessel models derived from both imaginary fantasies and manufactured utensils, modeling various conceptual and practical prototypes that characterize his corpus at large. Negotiating between human beings and lifeless artifacts, domestic objects and theatrical settings, fictional scenes and real-world objects, the scale-less and displaced kitchenware models accommodate the contradictions of Rossi's theory. By analyzing the analogical and repetitive operations in their development process, these models are posited as autonomous, generative and impenetrable object-subjects that engagingly advance architectural theory in a disciplinary sense. I argue that it is the physical existence of the kitchenware models-not the textual elaborations and logical deductions-that masters Rossi's unresolved struggle between dissonant yet irreducible ideas, and completes "the difficult whole."

Predicting burrowing owl flight trajectories in urban environments

It is important to understand how animals respond to changes in landscape structure, especially when considering habitat alteration and urbanization. Using the burrowing owl (Athene cunicularia) as an ecological model we tested two hypotheses: (1) the landscape of urban areas influences trajectories of the burrowing owl, which responds changing its displacement patterns, and (2) models incorporating species-specific traits, such as stochasticity and landscape perception, better predict flight trajectories than least-cost path models. Thirty owls were captured at the Brasilia International Airport, fitted with VHF transmitters, and released in random locations within 30 km of the airport. We generated a habitat suitability map for use as a resistance raster to model flight trajectories: one model was based on the least-cost path, and four models included stochasticity and variations of the owls' landscape perception and dependency on natural ecosystems. Observed trajectories were compared with those predicted by models using the following metrics extracted from the trajectories: mean habitat suitability values, sinuosity, and length. The best generalized linear models were selected using the Akaike information criterion. The owls dispersed through areas with a lower cost than expected by chance (z = 104.65, p < 0.05). More complex models performed better than the least-cost path model for suitability (r(2) = 0.18, p > 0.05), sinuosity (r(2) = 0.03, p > 0.05), and length (r(2) = 0.37, p > 0.05). Our results demonstrate that landscape information influences flight trajectories, and models incorporating landscape perception and stochasticity better predict burrowing owl flight trajectories.
