Integrated Fixed-Film/Activated Sludge (IFAS) technologies have been gaining wide popularity as an innovative and efficient treatment process for achieving nitrification in refining and petro-chemical wastewater treatment plants. IFAS technologies are sometimes referred to as Hybrid systems as the process combines the benefits of fixed film systems into the suspended growth activated sludge pro...

In this paper, instantaneous frequency amplitude spectrum (IFAS)-based fundamental frequency estimator is evaluated with speech signal corrupted by additive white gaussian noise. A key idea of the IFAS-based estimator is the use of degree of regularity of periodicity in spectrum of speech signal, defined by a quantity called harmonicity measure, for band selection in the fundamental frequency e...

Advanced compact wastewater treatment processes are being looked for by cities all over the world as effluent standards are becoming more stringent and land available for treatment plants more scarce. In this investigation, a new biofilm process for this purpose was studied. The design and operational criteria of a full scale extended aeration activated sludge system was compared with an H-IFAS...

The purpose of the experiments described in this article was the comparison of integrated fixed film activated sludge (IFAS) and activated sludge (AS) system. The IFAS applied system consists of the cigarette filter rods (wasted filter in tobacco factories) as a biofilm carrier. The comparison with activated sludge was performed by two parallel treatment lines. Organic substance, ammonia and TP...

Several assays have been developed for detection of immunoglobulin G antibodies to Human herpesvirus 8 (HHV-8), including immunofluorescence assays (IFAs) and enzyme-linked immunosorbent assays (ELISAs). However, the specificity and sensitivity of these assays are not completely defined due to the lack of a "gold standard." Although IFAs based on primary effusion lymphoma (PEL) cell lines are u...
