DICHO MIEMBRO TIENE ASIMISMO UNA PRIMERA REGION QUE COMPRENDE PRIMEROS MATERIALES; Y UN ELEMENTO ADICIONAL, EN CONTACTO CON LOS PRIMEROS MATERIALES Y CON (ii), QUE SE EXTIENDE HACIA EL INTERIOR DE UNA VECINA SEGUNDA REGION DE DICHO MIEMBRO PARA TRANSPORTE DE LIQUIDOS. ADEMAS, EL MIEMBRO TIENE UNA PRESION EN EL PUNTO DE BURBUJEO, MEDIDA CON AGUA DE TENSION SUPERFICIAL DE 72 mN/m, DE POR LO MENOS 1 KPa, SIENDO ESTA PRESION MAYOR A LA PRESION CAPILAR DEL ELEMENTO ADICIONAL. ASIMISMO, (i) Y (ii) SON DE MATERIAL SELECCIONADO DE GRUPOS DE FIBRAS, PARTICULADOS, ESPUMAS, ESPIRALES, ENTRE OTROS. SE REFIERE TAMBIEN A ARTICULOS QUE COMPRENDEN EL MIEMBRO DE TRANSPORTE YA DESCRITOINCLUDING: i) A REGION OF VOLUME THAT HAS AVERAGE Kb FLUID PERMEABILITY, OF WHEN LESS THAN 10-11 m² AND NO MORE THAN 10-² m², AVERAGE DENSITY, DRY, GREATER THAN 0.001 g / cm3, PORE SIZE OF AT LEAST 200 µm AND POROSITY OF WHEN LESS THAN 50%; ii) A WALL REGION THAT COMPLETELY CIRCUMSCRIBES THE REGION (i), INCLUDING A PORT REGION THAT HAS: POROSITY OF AT LEAST 10%, PORE SIZE NOT GREATER THAN 100 µm, THICKNESS dp AND AVERAGE PERMEABILITY kp OF AT LESS 6x10-20 m², ALSO HAVING A Kp / dp RATIO OF WHEN LESS 10-7 m; WHERE (i) IT HAS A kb GREATER THAN THE AVERAGE PERMEABILITY kp OF THE PORT REGIONS. SAID MEMBER ALSO HAS A FIRST REGION THAT INCLUDES FIRST MATERIALS; AND AN ADDITIONAL ELEMENT, IN CONTACT WITH THE FIRST MATERIALS AND WITH (ii), WHICH EXTENDS INTO A NEIGHBORHOOD IN THE SECOND REGION OF SAID MEMBER FOR TRANSPORTATION OF LIQUIDS. ALSO, THE MEMBER HAS A PRESSURE AT THE BUBBLING POINT, MEASURED WITH WATER WITH A SURFACE TENSION OF 72 mN / m, OF AT LEAST 1 KPa, THIS PRESSURE BEING GREATER THAN THE CAPILLARY PRESSURE OF THE ADDITIONAL ELEMENT. ALSO, (i) AND (ii) ARE OF MATERIAL SELECTED FROM GROUPS OF FIBERS, PARTICULATES, FOAMS, SPIRALS, AMONG OTHERS. IT ALSO REFERS TO ITEMS INCLUDING THE MEMBER OF TRANSPORTATION ALREADY DESCRIBED
