This paper propose a novel transmission line teaching aids using slow-wave transmission line technique. This teaching aids can help student observe the behavior of the electromagnetic wave in transmission line directly. This direct observation is important for the undergraduate who just study electromagnetics because the behaviors of the transmission line are abstractive, and hardly to be imagined...
Six isolates obtained from diesel oil enrichment culture were reconstituted to form a mixed microbial consortium. And the biodegradation test of diesel oil was conducted at 28°C over 5 weeks. An antibiotic selection strategy was adopted to determine the magnitude of specific isolates and population dynamics within the mixed culture during diesel oil biodegradation. During biodegradation test, the...
The influences of adding Tween60 and rhamnolipid on n-hexadecane biodegradation and cell surface characteristics such as cell surface hydrophobicity (CSH) and lipopolysaccharide (LPS) release for two strains of Pseudomonas and Sphingomonas were investigated. The results showed that the additions of Tween60 and rhamnolipid have different effects on the strains of Pseudomonas and Sphingomonas as these...
