one of the principles for designing and using the various units of water treatment plants is ability of assigning and predicting performance of those units in different and various conditions that could be checked by making pilot and could be modeled by means of available programs and software such as artificial neural network. at this study a model provided for predict performance of pressure ...

background: water filtration units have been faced problems in water turbidity removal related to their media, which is determined by qualitative indices. moreover, current qualitative indices such as turbidity and escaping particle number could not precisely determine the efficiency of the media in water filtration, so defining new indices is essential. in this study, the efficiency of anthrac...

Serum amylase activity was measured in 15 normal persons and in 60 liverdisease patients. Impairment of liver was assessed by serum bilirubin and thymol turbidity values. Most of the patients had serum amylase values that were well below the normal limits. Amylase activities were related to the degree of liver dysfunction, and serum amylase decreased as the bilirubin and turbidity values increa...

Turbidity measurements are inexpensive and can be performed rapidly and simply. Therc has bccn a necessity to develope a technique which could bc utiliscd with some degree of confidence to identify certain conditions rclatcd to potentially problcrnalic sugars. Nephelometric turbidity measurements were performed on a number of raw sugars and correlated with filterability dctcrmined routinely usi...

Maclagan (1944a) demonstrated that phenol and certain derivatives when dissolved in barbiturate buffer at pH 7.8 produced a turbidity with human sera. He observed that under specified conditions sera from normal persons gave a negligible turbidity, and the most marked turbidities occurred with sera from patients suffering from parenchymatous liver damage. The concentrations of phenol or phenol ...

It was observed by Maclagan that turbidity is produced in a barbital buffer saturated with thymol when specimens of serum from patients with diseases of the liver are added (1, 2). The degree of turbidity apparently varied with the degree of hepatic parenchymal damage. An analysis of the precipitate demonstrated that it contained globulin, phospholipid, cholesterol, and thymol. The mechanism of...

The effect of vanadate on the ATP-induced disruption of trypsin-treated axonemes and the ATP-induced straightening of rigor wave preparations of sea urchin sperm was investigated. Addition of ATP to a suspension of trypsin-treated axonemes results in a rapid decrease in turbidity (optical density measured at 350 nm) concomitant with the disruption of the axonemes by sliding between microtubules...

Is it possible to derive accurately Total Suspended Matter concentration or its proxy, turbidity, from remote sensing data in tropical coastal lagoon waters? To investigate this question, hyperspectral remote sensing reflectance, turbidity and chlorophyll pigment concentration were measured in three coral reef lagoons. The three sites enabled us to get data over very diverse environments: oligo...

background: ocsillator system is recognized by many water plant treatment designers for having many advantages, such as combination of mixing processes, flocculation and sedimentation processes in the same unit, the possibility of softening and lucidity simultaneously, and relatively acceptable efficiency. despite using this process in number of the regions in the country, enough researches hav...
