We prove that under rather general assumptions an exactly controllable problem is uniformly stabilizable with arbitrarily prescribed decay rates. Our approach is direct and constructive and avoids many of the technical difficulties associated with the usual methods based on Riccati equations. We give several applications for the wave equation and for Petrovsky systems.

Eighteen structurally varied amines were subjected to harsh oxidative conditions, and their stability was assessed seen in the context of biological thermal stability. Steric effects play a large role stabilization under presence carbon dioxide plays vital degradation pathway ethanolamine (MEA). Tertiary are generally very stable, known not form carbamates any extent. Many steric stabilization,...

Nanoparticles (NPs) developments advance innovative biomedical applications. However, complex interactions and the low colloidal stability of NPs in biological media restrict their widespread utilization. The influence properties on for gold with 5 40 nm diameter two surface modifications, methoxy-polyethylene glycol-sulfhydryl (PEG) citrate, NaCl human serum albumin (HSA) protein solution, is ...

This research evaluated the wastewater treatment system of Punta Carnero sector, in relation to pollutant efficiency load removal, final effluent quality and impact on ecosystem, finally determine if discharge can be reused for agricultural irrigation. The was based affluent characterization system, carried out three phases: i) Taking simple samples, analyzed an accredited water laboratory anal...
