Thirty-five years ago, B.F. Skinner (1976) lamented a decreasing trend in the prevalence of cumulative records in the Journal of the Experimental Analysis of Behavior ( JEAB). The editorial began with the two memorable lines, ‘‘Evidently we have not long to wait for an issue of JEAB without a single cumulative record! I shall not miss the records so much as the kinds of experiments that could s...

Triboelektrostatická separácia minerálnej substancie zo slovenského uhlia V článku sú diskutované niektoré technické aspekty triboelektrostatickej separácie a výsledky aplikácie tohto postupu pri úprave troch typov uhlia, konkrétne energetického uhlia z Cígľa, Handlovej a Novák. Bolo zistené, že účinnosť separácie veľmi úzko závisí na druhu separovan uhlia. Prvé výsledky preukázali súvislosť me...

The activated sludge process is the most widespread sewage treatment method. It typically consists of a pretreatment step, followed by primary settling tank, an aerobic degradation process, and, finally, secondary tank. effluent then usually chlorinated and discharged to water body. Tertiary aims at improving characteristics facilitate its reuse. In this work, through literature review prominen...

The operation of the Karašnica Water Treatment Plant, forming part water system in Ilijaš Municipality, Bosnia and Herzegovina, is analysed paper. Two distinct treatment lines are described analysed. first line consists an internal circular settling tank rapid sand gravity filters, while second external pressure filters. In order to evaluate operating efficiency, a tour facilities was made, int...

The authors conducted a study on treating synthetic dairy wastewater using aerobic granular sludge (AGS) in laboratory-scale continuous flow reactor (CFR) system. system consisted of an anaerobic reactor, and settling sedimentation tank, with different hydraulic retention times tested over 90-day period. monitored characteristics effluent treatment performance found that the achieved excellent ...

We determined the concentrations of 2-methylisoborneol (2-MIB) and geosmin in final effluent from wastewater treatment plants Kyoto City, Japan, investigating variations during treatment. The 2-MIB were 5.1–29.8 3.9–13.9 ng/L, respectively. Geosmin primary higher than those influent. concentration increased reactors, while that decreased. anaerobic-anoxic-oxic step-feed biological nitrogen remo...

The development of novel, non-sewered sanitation systems like the Nano Membrane Toilet requires thorough investigation processes that may seem well-understood. For example, unlike settling primary sludge, separation solids from liquids in a small-volume container at scale household toilet has not been studied before. In two sets experiments, real faeces and paper columns synthetic conical tank ...

The further goal of the model presented in this paper is to propose a digital tool predict behaviour main equipment water resource recovery facilities, secondary settling tank. Most time, models liquid/solid two-phase system are based on dynamic solid phase mass balance and velocity constitutive expression stemming from Kynch’assumption. here both momentum equations an explicit representation s...

In the conditions of progressive contamination surface sources water supply and inefficient wastewater treatment when using existing technologies, research problem justification use sorption materials for retention specific pollutants, in particular heavy metal ions radionuclides, is urgent. The parameters that determine efficiency sorbents are indicators their sedimentation rate. purpose exper...

This paper proposes the adaptation of Support Vector Data Description (SVDD) to the multiple kernel case (MK-SVDD), based on SimpleMKL. It also introduces a variant called Slim-MK-SVDD that is able to produce a tighter frontier around the data. For the sake of comparison, the equivalent methods are also developed for One-Class SVM, known to be very similar to SVDD for certain shapes of kernels....
