LAW CAPACITY WASTEWATER TREATMENT PLANTS

The question of small water users having no centralized wastewater collecting, cleaning and discharging system is of maximal actuality in Romania. Therefor economically efficient solutions are looked for. For disperse mountain villages, farms, or detached households traditional systems, with high maintenance expences because of long networks for small flows, can be economicaly not advantageos. Very small capacity treatement plants are a solution for such cases. The aim of the experimental part of the present work is to simulate situations, damages which can occur during running of a low capacity wastewater treatement plant. Low capacity hosehold wastewater treatement plants are economic alternatives which remove the disadvantages of emptyable basins namely the high costs, the frequvent empying operations, with unpleasant smelling, continous danger of groundwater infection, need for massive and expensive concrete buildings. The proposed plants are based on a classical treatement technology and need emptying of the exess mud only once or twice a year. In opposition with the case of classical plants, the mixture extracted from the proposed low cost systems does not smell and has a relatively low content of solid matter

ASPECTE ETICE PRIVIND RECOLTAREA SÂNGELUI DIN CORDONUL OMBILICAL ÎN SCOP DIAGNOSTIC

Aprofundarea studiilor privind mecanismele genetice şi epigenetice (determinate de mediu) ale atopiei a adus dezvăluiri privind debutul intrauterin al alergiei, dovedit de prezenţa IgE în sângele cordonului ombilical. Depistarea acestor nou-născuţi şi includerea lor într-un program de îngrijiri specifi ce reduc morbiditatea ulterioară din cadrul marşului alergic cu efecte incontestabile asupra calităţii vieţii şi a costurilor de îngrijire medicală. Creşterea dramatică a prevalenţei atopiei în ultimele decenii sugerează importanţa determinărilor IgE în cordonul ombilical. Utilizarea în scop diagnostic a sângelui cordonului ombilical impune însă legi şi reguli clare care fac obiectul dezbaterii din prezenta lucrare
