According to the new type of portable PLC programming device adopting the own invention technology, a PLC editor system with ARM microprocessor and μC/OS-II system as the core was constructed. Logic operation instructions with multiple operands and their encodes were designed. The data storage capacity was expanded. A CAN extension protocol was formulated. Two-way chain table was adopted to edi...

For next generation planar lightwave circuit (PLC) devices, high function and high-density integration are required as well as downsizing and cost reduction. To realize these needs, high refractive index difference between a core and a clad (∆) is required. To use PLC for practical applications, silica-based PLC is one of the most attractive candidate. However, degradation of the optical proper...

Two inositol phospholipid-specific phospholipase C (PLC) isozymes (PLC-I and -II) have been purified from bovine brain. When PLC-I or PLC-II was microinjected (100-700 micrograms/ml) into quiescent NIH 3T3 cells, a time- and dose-dependent induction of DNA synthesis occurred, as demonstrated by [3H]thymidine incorporation into nuclear DNA. In addition, approximately to 8 hr after PLC injection,...

To investigate the role of phospholipase C (PLC) in inflammatory processes, we tested 1-(6-((17beta-3-methoxyestra-1,3,5(10)-trien-17-yl)amino)hexyl)-1H-pyrrole-2,5-dione (U73122), a widely used PLC inhibitor, in several in vitro and in vivo assays. We first examined the effects of U73122 on human phospholipase C-beta (PLC-beta) isozymes and found that U73122 significantly inhibited recombinant...

Pre-treatment of rice roots for 2 h in aerobic conditions with two phospholipase C (PLC) antagonists, neomycin and compound 48/80 (C48/80), inhibited accumulation of gamma-aminobutyric acid and increased the loss of K+ in the medium during 3 h of anoxia. The presence of Ca2+ and A23187 (Ca2+ ionophore) nullified the effect of PLC inhibitors. Pre-treatment of rice roots with neomycin and C48/80 ...

Chemoattractants, including chemokines, play a central role in regulation of inflammatory reactions by attracting and activating leukocytes. These molecules have been found to regulate metabolism of phosphatidylinositol 4,5-bisphosphate (PtdIns(4,5)P(2)) via phospholipase C (PLC) and phosphoinositide 3-kinase (PI3K). Recent studies of mouse lines that lack PLC-(beta)2, PLC-(beta)3, or PI3K(gamm...

During the last years PLC technologies have been widely developed mainly due to new modulation techniques used for wireless telecommunication systems that can also be applied to PLC systems. The current state of the art of PLC communications is presents many possibilities and opportunities for the utilities. Besides the Distributed Energy Resources integration to the distribution grid is The ai...

In this paper, we show how research dealing with the design of a robust filter for manufacturing controllers can be used in the field of PLC training. Maintenance tasks and improvements in the manufacturing process involve changes in the PLC (programmable logic controller) program that can have bad safety consequences. Hence, a PLC program which is at the startup of the production lifecycle saf...
