Pharmaceuticals of emerging concern (acetaminophen (ACM), trimethoprim (TMP), oxytetracycline (OTC), and sulfamethoxazole (SMX)) were detected in water samples from aquaculture environments nonaquaculture sites four regions located on the northern coast Central Java. ACM was most prevalent pharmaceutical, with a mean concentration ranging not (n.d.) to 5.5 ± 1.9 ngL−1 (Brebes). Among target ant...

The transient behavior of the I-dimensional 2-state 3-input cellular automaton rule 110, one of the simplest "edge of chaos" cellular automata, is investigated numerically. The simulations show that the average transient time Tave increases algebraically with system size N, Tave ~ N"', with a "" 1.08, and that the density of propagating objects (gliders) decays with time as ngl ~ r'Y with I "" ...

Compared to other petroleum, the natural gas combustion remains cleanest and one showing less CO2 emission. These reasons make of important issues study. The separation NGL is energy intensive. This operation performed through a series column including debutanizer column. present work devoted optimize consumption at level response surface technique deploying central composite numerical design f...

Abstract The present study was carried out to investigate biodiesel production via transesterification of sunflower oil employing heterogeneous catalyst derived from indigenous ginger (Zingiber Officinale) leaves. It also aims compare the techno-economy performance ginger-based catalysts in 3 different forms viz. calcinated (CGL), activated by KOH (KGL) and NaOH (NGL). plant-based were characte...

Abstract In this work, Fe3O4-graphene oxide nanocomposite (GO-Fe3O4) was prepared as effective absorbent for magnetic solid phase extraction (MSPE) of trace quantities of cadmium ions in environmental water and rice samples using 1, 2-dihydroxy anthraquinone-3-sulphonic acid, sodium salt (Alizarin red S) and flame atomic absorption spectrometry (FAAS). The   GO-Fe3O4 was characterized by scanni...

in the present work a modified in-tube solid phase microextraction technique followed by gas chromatography-mass spectrometry (gc-ms) has been applied for determination of water odorants. geosmin, 2-methyl isoborneol, 2-isopropyl-3-methoxy pyrazine, 2-isobutyl-3-methoxy pyrazine and 2,4,6-trichloroanisol are of the most important odorants which have been studied. in the described method, analyt...
