Aspergillus terreus produces a unique enzyme, blasticidin S deaminase, which catalyzes the deamination of blasticidin S (BS), and in consequence confers high resistance to the antibiotic. A cDNA clone derived from the structural gene for BS deaminase (BSD) was isolated by transforming Escherichia coli with an Aspergillus cDNA expression library and directly(More)
Because of their appealing characteristics, quasi one-dimensional nanostructures like semiconducting nanowires have drawn much attention in the past decade. They can be utilized in a variety of applications such as field-effect transistors, chemical sensors, and photodectors. These devices are expected to deliver unprecedented performance because of the(More)
In this study, surfactant (hexadecyltrimethylammonium, HDTMA) modified zeolite (clinoptilolite) (SMZ) was used for simultaneous removal of ammonium and nitrate in wastewater, and the sorption properties of SMZ were determined. Results showed that natural clinoptilolite had good affinity for ammonium, but low sorption ability for nitrate, and the ammonium(More)
The prevalence of thyroid nodules in population is increasing around the world.To categorize thyroid nodules and stratify their malignant risk, thyroid imaging reporting and data system(TIRADS)was developed 6 years ago based on US , which is similar to breast imaging reporting and data system (BI-RADS). This paper aims at summarizing the particular content(More)
Nanoscale manipulation, which assembles nanostructures towards desired positions, plays a substantial role in the fabrication of nanowire based devices. Dielectrophoresis (DEP), the motion of dielectric particles inside a non-uniform electric field, is demonstrated to be an efficient method to manipulate nanowires. However, assembly of nanowires by DEP are(More)
In order to meet the requirements of intelligent windows in intelligent buildings, combined with PLC's high reliability, advanced control technology and touch screen's friendly interface, easy and flexible configuration programming, we designed the power window control system of intelligent machines based on the PLC and touch screen. Satisfactory results(More)
A Kelvin probe force microscopy (KPFM) image is sometimes difficult to interpret because it is a blurred representation of the true surface potential (SP) distribution of the materials under test. The reason for the blurring is that KPFM relies on the detection of electrostatic force, which is a long-range force compared to other surface forces. Usually,(More)
