This paper reviews the characteristics of copper slag and its effects on the engineering properties of cement, mortars and concrete.
To investigate the effect of this engineering approach on the capacity of the evolved clone to consume xylose in the presence of glucose, cells were pre-grown on in YNB medium containing different proportions of glucose-xylose until exponential growth phase and then transferred to a fermentation medium containing 2% xylose and 2% glucose.
Local residents were surveyed regarding their awareness of the scheme, and the causes of pollution, together with their perceptions as to the effects of the engineering works and of the resulting water quality improvements.
In this analysis, the effects of the engineering material constants for micropolar elasticity, the coupling number N, which is related to stresses, and the characteristic length l, which is related to couple stresses, are researched.
To investigate the effect of this engineering approach on the capacity of cells to consume xylose in the presence of glucose, cells were pre-grown on YNB-media containing different glucose-xylose mixtures and subsequently transferred to a fermentation medium containing 2% xylose and 2% glucose.
The three-dimensional deformation effect of the slope engineering in Antaibao under step-by-step excavation was analyzed and the stability of the slope engineering in the transition from surface to underground mining was evaluated.
The calculations and a serial of thermoluminescence experiments have been conducted to verify the effect of the trap engineering.
This study is the first to empirically demonstrate the effect of the ecosystem engineering by stem-boring insects on important attributes of arthropod communities.
Here, we expressed the bacterial polyhydroxybutyrate (PHB) pathway in the yeast Saccharomyces cerevisiae and we further evaluated the effect of engineering the formation of acetyl coenzyme A (acetyl-CoA), an intermediate of the central carbon metabolism and precursor of the PHB pathway, on heterologous PHB production by yeast.
We applied metabolic flux analysis to study the effect of engineering the novel biodegradation pathway into P. putida and to learn how the pathways influenced the existing metabolism of the cell.
