The Bill to unify the Civil and Commercial Code drafted by the commission appointed by Presidential Decree Nº 211 ofFebruary 23, 2011 contains majorreforms to Family Law, which we propase to list in this article. The most important ones are: changing traditional names. The explicit dwindling of personal responsibilities of marriage, including the weakening of the duties of fidelity and moral support. No1ault divorce. The regulation of cohabitation called domestic partnership. The establishment of responsibilities of step-parents. The acceptance of a third type of filiation. Filiation of a child born of assisted procreation. The possibility of prenuptial agreement. The establishment of a new, more complex, adoption procedure, with more actors and prevailing role of the administrative body. Family proceedings rules

The specific (COE) and individual (COI) oxygen consumption of Semimytilus algosus (0,0856 to 0,1869 g) were determinated in static closed chambers.(300 ml aprox.), using 3 concentrations of detergent (CO = 0,00; C1 = 0,02; C2 = 0,04; and C3 = 0,06 mg I-1 of detergent). To detect the dissolved oxygen was used the Winkler method. The filtration rate was determinated without detergent by filtration of Chaetoceros gracifis, with the same individuals as were exposed to the detergent during the respiration experiments. The experiment conditions were 35%. of salinity and 17 ± 0,5ºC. The results indicated that the detergent, even though it is biodegradable, at short periods of exposition disturbs the respiration rate increasing the oxygen consumption and velocity of filtration rate with the increase of detergent concentration.
