Partial nitrification of ammonia to nitrite was studied as a shortcut process to reduce the oxygen consumption during nitrification and the necessities of organic carbon compounds for denitrification in wastewater treatment plants (WWTP). This process is specially recommended for the treatment of wastewater containing low total organic carbon to nitrogen ratios (C/N) like the effluents of anaerobic digesters from the fish canning industry. These effluents contain residual carbon compounds and in some ...

Two cases of amyloid goitre presented as an enlarged thyroid mass with cystic components. Solid parts of the goitre showed high attenuation on computed tomography (CT) and moderate hypointensity on T1 and T2-weighted images. Fine needle aspiration was negative for amyloid, but pathological studies of surgical specimens demonstrated amyloid infiltration of the thyroid interstitium and regressive colloid cysts. In a patient at risk for systemic amyloidosis, thyroid enlargement with a cystic component ...
