PARA EL COLEGIO DE INGENIEROS

COMO INGENIERO QU~MICO AFILWO AL COLEGIO REGIONAL DE INGENIEROS QU~MICOS DEL LITORAL. QUIERO EXPRESARLES A TODOS MIS COLEGAS Y AMIGOS, UN MENSAJE DE FE. DE A L E G R ~ Y ESPERANZA EN MEJORES D~AS PORQUE ESTOY CONVENCIDO QUE LA INGENIER~ QU~MICA POCO A POCO SE IRA POSICIONANDO CADA VEZ MbS FUERTE EN EL DESARROLLO INDUSTRIAL DEL PA~S.
