Directed evolution is one of the powerful protein engineering tools that can change enzymes' substrate selec- tivity. The most challenging task of directed evolution is the efficient identification of desired mutants from a large mutant library23. As for coenzyme engineering, the use of 96-well ...
The Afromontane Floristic Region1,2 refers to a plant assemblage where a series of isolated highland forested areas are separated by lowland vegetation, and form an "archipelago-like" centre of endemism in the mountains of East and West Africa. The eastern part of this floristic region has ...
After comparing the changes in vegetation cover in the soil use/cover change zone and the unaltered zone, the authors pointed out that human activities have an important impact on the vegetation cover change. However, the authors did not further analyze the mechanisms and effects of the factors ...

Thus, FFF can produce a prototype or a finished product from a Computer Aided Design (CAD) model without the use of molds. Despite the potential disruptive character of FFF, in practice 3D printed parts of- ten show unsatisfactory mechanical resistance [7]. This is generally due to ...

The results showed that the slag of the CaO-Al2O3-CaF2- BaF2-SiO2-MgO system was effective for use in nitrogen desorption from molten steel and that the rate of nitrogen transfer from steel to a gas phase could be increased. Although some studies have confirmed the phenomenon of nitrogen ...

A series of issues has been raised by the rapid development of urbanization, such as the large numbers of greenhouse gas emissions of urban systems, the sprawling layout of urban spaces, and the disordered use of land, leading some to take climate issues more seriously. Therefore, urban ...
