Experimental investigation of mold growth risk among typical residential indoor materials: Case study in coastal city, China

Mold growth poses significant threats to building structures and occupant health, particularly in regions with high air humidity. Existing mold prediction models involve fewer categories of building materials and are less reliable in predicting complex real environments. This research investigated mold growth risk of ten typical residential indoor materials. Firstly, this work carried out meticulous sampling in a residential building, followed by incubation tests in a controlled mold incubator, and evaluated by the mold growth index. The results revealed varying degrees of mold growth risk among different materials at different relative humidity (RH) levels. Paints exhibited a generally low susceptibility to mold contamination, while panels and wallcovering displayed a higher risk of mold growth. Under high humidity, mold growth was observed in the panels on the first day of inoculation. Conversely, 25 % of the latex paints did not reach index 1 at the end of the experiment. The results showed that below 75 % RH at 25 °C was a safe area for all experimental materials. Moreover, experimental results indicated that a lag approximately one-week in the appearance of mold was observed when the RH was reduced by 10 %. However, the final mold growth index did not differ by more than one grade after the test cycle.

Parenting in Proximity to Others: The Importance of Transitions and Trajectories

ABSTRACT In many cities, living in an apartment throughout the life-course challenges the status-quo. While density is acceptable during some life-stages, the default is the detached dwelling during others. The parenting period is one such stage. Using records of the experiences of 20 parents of children 0-5 in apartments in Sydney, Australia, this paper questions the adequacy of density for family life in the case-study city. We add a unique focus on temporality, conceptualising densification and parenting as projects in transition. Our analysis reveals disruptions to densified family life, suggesting that the process of densification is at odds with the timings of childhood and the urgency of the problems perpetuated by lower-density urban form.

Unfolding the spatial spillover effect of urbanization on composite ecosystem services: A case study in cities of Yellow River Basin

River basins play an important role in national economic development and ecological security and can be well expressed by ecosystem services (ESs) research. Due to rapid population growth and climate change, it has had a significant impact on the ecosystem of the Yellow River Basin (YRB). Although ESs have been assessed in several studies, few studies have used a composite ecosystem service index (CESI) in their assessment. Thus, here, based on the InVEST model, bivariate spatial autocorrelation, and spatial econometric model, we studied the composite ESs in the YRB, with an aim to build a CESI for evaluating the overall ESs in the YRB. We found that the CESI of the YRB from 1990 year–2020 year had an obvious spatiotemporal distribution law at the city level and grid scale, showing a high distribution characteristic in the southeast. The spatial trend also showed a significant difference in regional distribution. There was a positive spatial correlation between the CESI and urbanization indicators that reflected the level of urbanization, and the distribution of the aggregation type among the three was similar. Furthermore, population density had a strong positive spillover effect on the CESI, whereas economic density and land development had a negative spillover effect. Therefore, the YRB should pay attention to transforming the extensive development model and paying attention to the negative spillover effect of economic density when laying out industrial structures. Additionally, it is necessary to control the expansion of built-up land and improve land use efficiency, thereby reducing the negative spillover effect of land development. This study’s findings can serve as reference for policy formulation in major river basins worldwide.

Early involvement of stakeholders in mobility-related projects

Early involvement of stakeholders could help identifying potential difficulties and providing input during the development period. The involvement of stakeholders is a key criterion for sustainable urban transportation planning. Stakeholders should be able to express their opinions and concerns while also contributing creative and innovative solutions to transportation issues. Therefore, the study’s goal is to give a voice to stakeholders who are generally mute or are not participating in the early planning stages (non-expert citizens). Semi-structured interviews were conducted over a two-week period, in addition to observations of mobility patterns and street talks. The analysis is conducted in response to the following research question: How early involvement of stakeholders in mobility-related projects might aid in the development of methodologies and strategies for enhanced active mobility with a case study in Trondheim city. The results are presented from three perspectives: active mobility obstacles in the Elgeseter district, active mobility drivers in the Elgeseter district, and viable solutions as perceived from the perspectives of experts and non-expert citizens. Based on the findings, comprehensive planning procedures covering everything from land use to municipal infrastructure design will be required. Such techniques are required to persuade people to use green, sustainable modes of transportation as a lifestyle choice rather than a legal requirement and involving citizens in project development at an early stage can be extremely effective in this regard. The study contributes to our understanding of the factors influencing commuters’ desire to engage in early phase of mobility related projects.

Project for the development of the Eurasian transport framework in the countries of Central Asia

The paper puts the importance of an international transport corridor for the Republic of Kazakhstan. Two directions of railway communication within the latitudinal Central Eurasian Corridor have been identified. A technique has been developed for applying simulation modeling to identify the bottlenecks on the way of railway flows. Bottlenecks include the intersections of vehicular and pedestrian traffic with rail traffic. In such places, conflicting flows are formed, which may be accompanied by a merger of individual flows. Using the methods of structural analysis, synthesis, system analysis and step-by-step inclusion (or exclusion), the input parameters of simulation models of objects and processes have been established for the case study of Aktobe city in the Republic of Kazakhstan. A graphical model of the behavior of groups of objects for conflicting flows in bottlenecks has been developed, being the basis for the simulation model.

A Linear Regression Study Relating Stray Animal Management with the Importance of Relative Funding. A Case Study in a Small Greek City

Cities all around the world face the constant difficulty of regulating stray animal populations in urban environments. Abandoned or lost dogs and cats find refuge on urban streets, where they face a variety of challenges. This essay dives into the complex subject of managing stray animal populations in metropolitan areas. Stray animals on the streets are malnourished, exposed to harsh weather conditions, and infected, creating a huge public health concern by spreading illnesses such as rabies. Collaboration among communities, local governments, and animal welfare groups is critical in combating this issue efficiently. Implementing large spay and neuter programs, building animal shelters, and encouraging ethical pet ownership are all popular solutions for addressing this issue. To create safer and more compassionate urban settings for both humans and animals, it is critical to invest in vaccination and disease prevention programs, strengthen animal welfare regulations, and encourage community involvement. This study will use data from a municipality in Greece's Attica area to evaluate the link between greater spending and improved stray animal management. The examination of yearly veterinary care costs demonstrates an increase in financing but no commensurate increase in the number of animals seeking veterinary treatment. As a result, state and local authorities must take a more targeted and efficient approach to addressing this disparity. Although the state is willing, the challenge of reducing stray animal numbers persists, requiring ongoing attention and financial support. Cities can strive towards creating inclusive and healthier urban environments for all residents by addressing root causes and implementing viable solutions. This paper proposes a more targeted approach to tackling this complex issue.

Assessment of waste management practices and waste banks in urban areas of Indonesia: A case study of East Jakarta and Depok City

The rapid population growth in major cities in Indonesia, including East Jakarta and Depok City, has resulted in increased consumption patterns that have an impact on the quantity and quality of generated waste. These communities’ current waste management practices are inadequate, encompassing sorting, collection, and processing—evaluating existing waste management conditions involve sampling, observation, interviews, and questionnaires. In Pancoran Mas, the average waste generation was found to be 0.24 kg per person per day, with food waste comprising 51% and plastic waste 18%. Pulo Gebang exhibited similar results, with a waste generation rate of 0.22 kg per person per day, consisting of organic waste accounting for 46.7% and plastic waste at 19%. However, both districts have established Waste Banks, namely Hasvil (HWB) and Sekar Wangi (SWB) in Pancoran Mas and Pulo Gebang. The waste bank data revealed that HWB had a waste generation rate of 0.08 kg per person per day, while SWB had a rate of 0.12 kg per person per day, predominantly paper waste. HWB successfully reduced individual waste going to landfills by 33% for approximately 120 people, whereas SWB achieved a reduction of 52% for around 80 people.

Natural dynamics and watershed approach incorporation in urban water management: A scoping review.

Several cities are facing water emergencies related to urbanization impact and amplified by climate change. Most of the cities have responded to these crises through short-term measures. However, some cities have incorporated a watershed approach to water management in seeking more sustainable solutions. Although the importance of a watershed approach in land management is generally acknowledged, studies on this topic have typically focused on theoretical models, water management in rural areas or single case-studies of cities or countries. In this research, a scoping review of the literature was performed, based on the PRISMA 2020 statement, in three databases: Web of Science, Google Scholar and SciELO. Forty-one studies were identified analyzing 17 city cases implementing urban actions from a watershed approach in water management. These cities were from the Global North and Asian rising world powers. The lack of results of cities from the Global South, based on the research undertaken, was the main limitation and bias identified. Most of the Global South results identified in this research were theoretical models, scenarios and cases of rural areas instead of urban contexts. The results obtained indicate that the main motivations for cities to implement a watershed approach were water scarcity, floods and contamination of water bodies. The implemented actions focused on the shift from gray to green and blue infrastructure and on conservation measures. Lastly, the challenges to introduce those actions were mainly the lack of economic investment, insufficient experience, stakeholder opposition, and regulatory obstacles. Urban water management could be seen as an opportunity to change the way we relate to urban territory. Incorporating a watershed approach into urban planning and water management could promote more sustainable cities.

The potential of combining passenger rail with freight: A New York City case study

Utilizing passenger rail, including subways, to transport goods can have advantages over trucking in terms of efficiency and emissions. While some experimentation is ongoing in this area, combined passenger and rail opportunities in specific cities merit further attention. To more concretely examine how to leverage passenger rail for freight, this paper explores the potential of utilizing unused capacity in New York City (NYC) subway trains for transporting goods. Using General Transit Feed Specification (GTFS), rail and passenger data for the NYC subway, we found ways to use excess capacity and existing rail lines for freight transportation. We visualized a freight train timetable and graph, analyzed meet-errors between freight and passenger trains, and formulated prevention policies. Using U.S. Environmental Protection Agency data, we estimated emission reductions from replacing trucks with unused subway capacity. Our findings suggest that with adequate policies, investments and redesign, combining passenger rai and freight in the subways could significantly reduce truck trips, traffic congestion, and greenhouse gas emissions compared to trucking alone. However, implementing this approach requires careful collaborative planning, investment, enhanced security screening, and streamlined operations to minimize impacts on passenger transport. Further efforts should explore in more depth the costs and benefits and practical design and policy issues around using excess passenger rail capacity for freight transport in NYC and other cities.
