⢠characterize a level process; ⢠use the PLC to implement a batch process; ⢠use the PLC to implement closed-loop control of a level process;
First you need to design a control system for a batch process in which a liquid at room temperature (20o C) is pumped into a tank until a given level is reached. The liquid is then heated and mixed, after which is evacuated. The system will work in five different states:
Sample Solution
In recent years, polymerânanoparticle composite materials have attracted the attention of a number of researchers, due to their synergistic and hybrid properties derived from several components. Whether in solution or in bulk, these materials offer unique properties (mechanical, electrical, optical and thermal) [69]. The field of polymer nanoparticles (PNP) is rapidly growing and playing a pivotal role in a broad spectrum of areas ranging from electronics to the Photonics, conducting materials to sensors, medicine to biotechnology, pollution control of environmental technology, and so forth, during the last decades [70, 71] . New and newer polymers have been trying to develop nanoparticles for their application as drug carriers. Craparo et al., 2008 described the preparation and physicochemical and in vitro biological characterization of nanoparticles based on PEGylated, acryloylated polyaspartamide polymers. Polymeric nanoparticles can be defined as colloidal particles ranging between 10 and 1000 nm in size and composed of either natural or artificial polymers [73]. Polymeric nanoparticles composed of the drug dispersed in an amorphous form within a polymer matrix. PNPs are promising vehicles for drug delivery by easy manipulation to prepare carriers with the objective of delivering the drugs to specific targets; such an advantage modifies the drug safety [74]. The compounds of interest are very beneficial for drug delivery applications because of their ability to control drug release and their protection properties [75]. Currently, stimuli-sensitive nanoparticles which affected by the changes in pH, temperature and magnetic fields gained great concern [76-79].>
