This paper develops a calculation process for PT endogenous demand with respect to social costs in motorcycle-dominated mixed transport systems, based on the total social cost of public transport in previous research. The incremental elasticity analysis is used to estimate the endogenous passenger demand for dedicated PT technologies.

In the design and calculation of stormwater drainage systems, the design rainfall intensity plays a crucial role and is widely used in runoff calculations. Due to the influence of local climatic factors, the selection of probability distributions for rainfall frequency analysis and the methods used to determine parameters for empirical equations result in a variety of equations compared to traditional Rainfall Intensity-Duration-Frequency curves.

The heating, ventilation, and air conditioning (HVAC) system consumes a lot of electricity in the building to meet the demand for thermal comfort. The energy recovery ventilator (ERV) has been used in commercial, industrial, and residential buildings to save energy consumption for HVAC systems. In this study, we investigated the efficiency of ERV systems in different construction climate zones in Vietnam and the energy consumption of the sample primary school.

The study investigated the antifungal activity against Aspergillus niger CBS 76997 and Penicillium oxalicum 20B of several Lactobacillus strains (LAB). The in vitro antifungal activity of cell-free supernatants and biomass of Lactobacillus strains against the growth of A. niger CBS 76997 and P. oxalicum 20B was determined by monitoring the fungal colony diameter over time by spot inoculation method and double layer method.

lectric Arc Furnace Dust (EAFD) and wasted glass are two types of waste in industry and daily life, so they must be recycled to recover some useful elements. The production of colored glass is one of the methods used to recycle the electric arc furnace dust to take advantage of the coloring element in the dust. To use this colored glass for decoration, it is also necessary to test its durability. The present study focuses on the properties of colored glass when using electric furnace dust.
