1.Cutting structure is force balanced and bit blade is asymmetrically designed so that the load on bit is balanced that resulting better stability of the bit. 2.Main cutter are high performance PDC cutters to insure service life of the bit while improving RO...
The Stinger PDC cutter has superior impact resistance, wear resistance, and rock-breaking efficiency compared to the conventional PDC cutter. Thus, hybrid PDC bits that combine conventional and Stinger PDC cutters have significant advantages in drilling hard, interbedded, and highly abrasive rocks. ...
The western blot analysis confirmed the presence of PDC-109 isoform proteins at 15.4kDa (pI 5.3 and 5.5). The seminal plasma protein PDC-109 was abundant in the low fertile when compared to the high fertile group (p<0.05). This study suggests that the imbalance in acidic and basic sperm ...

The crystal structure of the complex between PDC and cesium (Cs) ion suggests that the metal ion binary crosslinking and much coordination numbers of the Cs induce the preferential complex formation via sedimentation of the PDC鈥揅s complex. The minor electronegativity difference between the Cs and...
Elevated and chronic activation of pDC are implicated in autoimmune disease like systemic lupus erythematosus and rheumatoid arthritis. Delta(9)-tetrahydrocannabinol (THC) is a well characterized cannabinoid with potent anti-inflammatory activity, but acceptance of THC as a treatment for autoimmune ...
