Sustainability in land use plays an important role in the urbanization process toward achieving the goals of the 2030 Agenda for Sustainable Development. This study integrates Earth observation data through satellite imagery analysis combined with field surveys to assess the Urban Land Use Efficiency (ULUE) by using the land use efficiency index, estimates the relationship between land use, population growth, and the urbanization process in Thang Loi ward over a 20-year period. The findings reveal inefficient urban land use, where the expansion rate of built-up areas exceeds the population growth rate in the studied area. From 2002 to 2022, the population and built-up area increased by 339% and 460%, respectively. In most of the expanding areas, there is widespread hoarding and fragmentation of land use, with numerous plots of land being vacant or underutilized for many years due to lack of control. Therefore, to improve land productivity and ensure sustainable urban growth, the local government should consider improving the Urban Land Use Efficiency Index.

In this paper, MIL-53(Al) was synthesized by solvothermal method and its application as an adsorbent to remove rhodamine B from aqueous solution. The material was characterized using X-ray diffraction, Fourier-transform infrared spectroscopy, nitrogen adsorption-desorption isotherms, and scanning electron microscopy. The results show that the material has a large specific surface area (1028.3 m2/g). The rhodamine B adsorption on MIL-53(Al) occurs very quickly in the first minutes of contact. Two pseudo-first order and pseudo-second order adsorption kinetic models, and two adsorption isotherm models, including Langmuir and Freundlich, were used to analyze the adsorption data.

Abstract: Urban agriculture is a highly concerned issue during the period of rapid urbanization in Vietnam. Research aims to propose a cultivation process for cultivating oyster mushrooms, utilizing coffee grounds from coffee businesses as a resource. This approach promotes circular economy principles, generating economic benefits for households while protecting the environment and being suitable for urban areas. The study conducted experiments on grey oyster mushrooms using different mixtures of coffee grounds and rubber wood sawdust at the following ratios: 0%, 25%, 50%, 75%, and 100% coffee grounds/rubber wood sawdust, filled into bags with a weight of 1.2kg. The research results showed that disease infection rates were mild in the 0% and 25% mixture ratios, while the remaining ratios exhibited moderate to severe infection levels. The highest mushroom yield was observed in the mixture ratio of 25% coffee grounds, with an average number of mushroom ears per bag reaching 29.7grams/bag, the dry weight is 63.8 grams/bag, with an average size ranging from 3 to 14 cm and a moisture content of 79.5%. The fastest colonization speed on the substrate is achieved by 25%, 50% coffee grounds blend, which fully colonizes the bag in a period of 25 to 35 days, the shortest time compared to the 75% and 100% coffee grounds blends, which take 40 to 45 days. The experimental results show that the 25% coffee grounds: 75% rubber sawdust blend is suitable for urban mushroom cultivation models and can be expanded on a large-scale farm, contributing to minimizing environmental pollution, utilizing limited urban land area, and providing high economic efficiency.

In engineering and science problems, the data being considered are often known in the form of sets of discrete points, not as a continuous function. In applications, the values of the discrete data at specific points may be required to estimate. To solve these problems, a common mathematical approach is to use the interpolation method. In this paper, we use the cubic natural spline interpolation method to build approximate functions for some real data in Vietnam such as data on rice output and rice area of cultivation, data on expenditure and income per capita. The data used in this paper are extracted from the General Statistics Office of Vietnam. We develop some Matlab programs to find the coefficients of splines and calculate the values of the interpolation functions at specific points. Using the obtained interpolation function, some missing values in the data on income and expenditure per capita in the Southeast region of Vietnam in 2019 and 2021 are estimated. Furthermore, some unknown data on rice productivity and cultivation area are obtained in a similar manner. A good agreement between the calculated values and actual values are found.
