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.

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.

In the study, the total nitrogen content of natural rubber was determined to evaluate the effectiveness of deproteinization on the synthesis of chemically modified rubber materials. The remaining protein content in the obtained deproteinized natural rubber (DPNR) was analyzed as nitrogen content using the Kjeldahl 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.

Titanium dioxide (TiO2) particles were synthesized by the sol-gel method (SG) and sol-gel low-temperature method (SG-L), utilizing titanium isopropoxide as the precursor. Subsequently, the particles underwent heat treatment with sodium hydroxide 10M, resulting in samples denoted as SG-H and SG-L-H samples, respectively.

The limits of current micro-scale technology is approaching rapidly. As the technology is going toward nano-scale devices, physical phenomena involved are fundamentally different from micro-scale ones. Principles in classical physics are no longer powerful enough to explicate the phenomena involved in nano-scale devices. At this stage, quantum mechanic sheds some light on those topics which cannot be described by classical physics. The primary focus of this research work is the development of an analysis technique for understanding the behavior of strongly perturbed harmonic oscillators.
