Tree Adjoining Grammar (TAG) is a useful formalism for describing the syntactic structure of natural languages. In practice, a large part of wide coverage TAGs is formed by trees that satisfy the restrictions imposed by Tree Insertion Grammar (TIG), a simpler formalism. This characteristic can be used to reduce the practical complexity of TAG parsing, applying the standard adjunction operation ...

Tigecycline (TIG) is approved for use for the treatment of complicated intra-abdominal infections, skin and skin structure infections, as well as pneumonia. Acquired resistance or reduced susceptibility to TIG has been observed in Gram-negative rods, has seldom been reported in Gram-positive organisms, and has not yet been reported in Enterococcus faecium. Using the serial passage method, in vi...

The present paper describes fuzzy logic simulation of tungsten inert gas welding (TIG) process to predict the weldment macrostructure zones' shape profile characteristics. The prediction of the weld pool geometry together with the shape of the heat affected zone (HAZ) was accomplished taking into account of TIG welding process parameters such as arc traverse speed, welding current and arc lengt...

Experiments have been conducted to investigate the influence of cusp external magnetic field (EMF) on deposition rate two-electrode tungsten insert gas (T-TIG) welding. T-TIG arc parameters such as shape, voltage, pressure, and plasma information were acquired respectively. Results showed that compared TIG a higher welding current could be allowed for due its low pressure characteristic. Under ...

Recently, we demonstrated that the anti-bacterial agent tigecycline preferentially induces death in leukemia cells through the inhibition of mitochondrial protein synthesis. Here, we sought to understand mechanisms of resistance to tigecycline by establishing a leukemia cell line resistant to the drug. TEX leukemia cells were treated with increasing concentrations of tigecycline over 4 months a...

This study evaluated the tensile and flexural strength of tungsten inert gas (TIG) welds in specimens made of commercially pure titanium (CP Ti) compared with laser welds. Sixty cylindrical specimens (2 mm diameter x 55 mm thick) were randomly assigned to 3 groups for each test (n=10): no welding (control), TIG welding (10 V, 36 A, 8 s) and Nd:YAG laser welding (380 V, 8 ms). The specimens were...

In order to establish titanium welding technology TIG arc weldability and MIG arc weldability were surveyed. For TIG arc weldability influence of arc length and thickness to proper region of welding condition became obvious. For MIG arc weldability a new method to defend wandering phenomenon was developed.
