In this study, a sequencing batch reactor (SBR) with aerobic granular sludge (AGS) was operated synthetic wastewater containing environmental relevant concentrations of 17β-estradiol (E2), 17α-ethinylestradiol (EE2) and sulfamethoxazole (SMX). Despite the presence studied PhAC, fraction clearly predominated (TSSgran/TSS ranging from 0.82 to 0.98) throughout monitoring period, presenting aggrega...

In UCT and Bardenpho systems, by starting with 100 per cent municipal waste water as influent, incrementally decreasing the waste-water fraction and increasing the acetate fraction, an enhanced culture of polyphosphate (polyP) organisms was developed. Aerobic cultures, using the API procedure, indicated greater than 90 per cent of the microorganisms as Acinetobacter spp. As the acetate fraction...

Coastal aquaculture can contribute to eutrophication of receiving waters. New technologies and improved management practices allow the aquaculture industry to be more sustainable and economically viable. Current practices, however, do not provide an additional use for effluent water. Nitrogen, phosphorus and other effluent compounds could be valuable plant nutrients. Inflow and effluent water f...

This paper presents a new variable step-size normalized subband adaptive filter (VSS-NSAF) algorithm. The proposed algorithm uses the prior knowledge of the system impulse response statistics and the optimal step-size vector is obtained by minimizing the mean-square deviation(MSD). In comparison with NSAF, the VSS-NSAF algorithm has faster convergence speed and lower MSD. To reduce the computa...

This research describes the results of anaerobic digestion gelatine as a potential hydrogen source with heat-shocked inoculum. The concentrations applied were VSS (volatile suspended solids) ranging from 10 g VSS/L to 30 VSS/L. initial process pH was 5.5, and, depending on concentration, reached values 7.5 7.8 after 55 days. Although inoculum in collagen, that occurred hydrogenotrophic digestio...

BACKGROUND Vertigo Symptom Scale (VSS) is a proper instrument for assessing the patient status, clarifying the symptoms, and examining the relative impact of the vertigo and anxiety on reported handicap. Our aim is the translation and cross-cultural adaptation of the VSS into Persian language (VSS-P) and investigating its validity and reliability in patients with peripheral vestibular disorders...

This paper extends the recently introduced variable step-size (VSS) approach to the family of adaptive filter algorithms. This method uses prior knowledge of the channel impulse response statistic. Accordingly, optimal stepsize vector is obtained by minimizing the mean-square deviation (MSD). The presented algorithms are the VSS affine projection algorithm (VSS-APA), the VSS selective partial u...

BACKGROUND Dizziness and comorbid anxiety may cause severe disability of patients with vestibulopathy, but can be addressed effectively with rehabilitation. For an individually adapted treatment, a structured assessment is needed. The Vertigo Symptom Scale (VSS) with two subscales assessing vertigo symptoms (VSS-VER) and associated symptoms (VSS-AA) might be used for this purpose. As there was ...
