Abstract:

Cities are heterogeneous environments, and pollutant concentrations are often higher in streets compared with in the upper roughness sublayer (urban background) and cannot be represented using chemical-transport models that have a spatial resolution on the order of kilometers. Computational Fluid Dynamics (CFD) models coupled to chemistry/aerosol models may be used to compute the pollutant concentrations at high resolution over limited areas of cities; however, they are too expensive to use over a whole city. Hence, simplified street-network models, such as the Model of Urban Network of Inters

Abstract. Regional-scale chemistry-transport models have coarse spatial resolution (coarser than 1 km ×1 km) and can thus only simulate background concentrations. They fail to simulate the high concentrations observed close to roads and in streets, where a large part of the urban population lives. Local-scale models may be used to simulate concentrations in streets. They often assume that background concentrations are constant and/or use simplified chemistry. Recently developed, the multi-scale model Street-in-Grid (SinG) estimates gaseous pollutant concentrations simultaneously at local and r

Abstract:

By extracting and simplifying the characteristics of commercial streets with arcades (Qilou) in Nanning, the tissue map of Qilou streets which reflects the urban morphology, including the road network form, block scale, building scale and other characteristics in a hot and humid area is obtained. In addition, the sunshine simulation is performed by using sunshine design software in an environment comprising streets with arcades to simulate street sunlight environments under various conditions. The relationship among street height-to-width ratio, sunshine hours, and street orientation angle is

Abstract:

Pedestrian commercial streets are an important part of a city. However, the open outdoor street is easily affected by the external climate, and a poor microclimate environment can indirectly affect the volume of visitors to the commercial street. This paper takes pedestrian commercial streets in regions with hot summers and cold winters as the research object in order to obtain reasonable prototypes of street space. Adopting the experimental method of controlling variables, microclimate simulation analysis is conducted on different street flow lines, various locations of open space, and the di

Streets perform a number of important functions and have a wide range of activities performed in them. There is a small but growing focus on streets as a more generalisable, atomised, and therefore more manageable unit of development and analysis than cities.

People who do not know about the history of the dead people they can learn about the dead person’s history through those songs. A musical instrument known as Roar is played in death house.

Although these sequenced patterns are sourced from Yoruba everyday sentences and oral genres (proverbs, poetry, praise-chants, and idiomatic phrases), the drummers also embrace other social narratives.

Abstract:

Resilient cities incorporate a social, ecological, and technological systems perspective through their trees, both in urban and peri-urban forests and linear street trees, and help promote and understand the concept of ecosystem resilience. Urban tree inventories usually involve the collection of field data on the location, genus, species, crown shape and volume, diameter, height, and health status of these trees. In this work, we have developed a multi-stage methodology to update urban tree inventories in a fully automatic way, and we have applied it in the city of Pamplona (Spain). We have c

Abstract:

Traffic-related air pollution in street canyons can cause health problems for pedestrians. In order to clarify the behavior of reactive pollutants, such as NOx and O3, in street canyons, a computational fluid dynamics (CFD) model coupled with a chemistry model and tree canopy model was developed, and then, a set of numerical experiments were performed to investigate the impacts of chemical reactions and aerodynamic effects of trees planted in a canyon. The results were compared with the observation data. Through the results of the numerical experiments designed to simulate a realistic urban st

Abstract:

Street view images are emerging as new street-level sources of urban environmental information. Accurate detection and quantification of urban air conditioners is crucial for evaluating the resilience of urban residential areas to heat wave disasters and formulating effective disaster prevention policies. Utilizing street view image data to predict the spatial coverage of urban air conditioners offers a simple and effective solution. However, detecting and accurately counting air conditioners in complex street-view environments remains challenging. This study introduced 3D parameter-free atten

Abstract:

Background. Foodborne outbreaks and epidemic diseases are common in resource-limited countries. Many people in developing countries are increasing their habit of eating fast foods prepared on the street due to their low cost and accessibility, while most of them get sick due to poor food hygiene practices and safety measures among the street food vendors. Therefore, this research is aimed at assessing food hygiene knowledge, practices, and associated factors among street food vendors. Methods. A community-based cross-sectional study design was conducted among 494 street food vendors in Addis A

Abstract Physical simulation was used to study pollution dispersion in a street canyon. The street canyon model was designed to study the effect of measuring flow and concentration fields. A method of CO2-laser photoacoustic spectrometry was applied for detection of trace concentration of gas pollution. The advantage of this method is its high sensitivity and broad dynamic range, permitting monitoring of concentrations from trace to saturation values. Application of this method enabled us to propose a simple model based on line permeation pollutant source, developed on the principle of concent

Our investigation focused on air pollution across five locations in Kuršėnai, utilizing lichen bioindicator species, the maple leaf tar spot (fungus Rhytisma acerinum) test, and metal corrosion indicators. Comparative analysis of the data revealed almost identical results across different methodologies. The cleanest air was near the gymnasium, likely due to the distance of the maple trees from the road and vehicular traffic. Conversely, the most

Nowadays, we observe our cities turbulent and unorganized in respect to color. Inconsistent locating of the buildings along with each other, the use of inhomogeneous colors, and the lack of attention to the psychological properties of colors have created the spaces in cities that are not compatible with the spirit of human and we do not feel relaxation in them any longer. This article is an attempt to express the importance of color theme and how to handle and use it in the city.
