Synthetic fibers enter wastewater treatment plants together with natural fibers, which may affect efficiency, a fact not considered in previous studies. Therefore, the aim of present study was to evaluate efficiency coagulation/flocculation process for removal mixture textile from different water matrices. Natural and synthetic (100 mg/L; cotton, polyacrylonitrile, polyamide) were added matrix,...

This study evaluated the effects of potassium and sodium carbonate bicarbonate, Bacillus subtilis (Cohn, 1872) QST-713, pumilus (Meyer & Gottheil, 1901) QST-2808, crude roasted coffee oils on inhibition mycelial growth conidial germination in Botrytis cinerea Pers.: Fr colonization begonia (Begonia elatior Hort. ex Steud) leaf discs by B. inoculated before, simultaneously after with these alter...

Foliar sprays of three plant resistance inducers, including chitosan (CH), potassium sorbate (PS) (C6H7kO2), and potassium bicarbonates (PB) (KHCO3), were used for resistance inducing against Erysiphe cichoracearum DC (powdery mildew) infecting okra plants. Experiments under green house and field conditions showed that, the powdery mildew disease severity was significantly reduced with all test...

Analyses have been made of the inorganic constituents of the juices expressed from the leaves of Rheum, Rumex, and Oxalis. It has been shown that in all cases there is a large excess of inorganic cations over anions in the sap, the average ratio of cations to anions being 3.8 (Part 1, p. 239). The ash analyses of plant tissues (chiefly leaves) reported in the literature have been examined criti...

Saliva as a diagnostic specimen can give not only the same information as serum testing, but also additional or new information that cannot be obtained from serum. 1 Saliva in humans is a mouth fluid possessing several functions involved in oral health and homeostasis, with an active protective role in maintaining oral healthiness. Saliva helps bolus formation by moistening food, protects the o...

In this study, a process for preparing battery-grade lithium carbonate with lithium-rich solution obtained from the low leaching of fly ash by adsorption method was proposed. A carbonization-decomposition carried out to remove impurities such as iron and aluminum. First, primary Li2CO3 treated CO2 get more soluble bicarbonates. The decomposition LiHCO3 produced insoluble at 90 °C And smashed ai...

Cu(I)-catalyzed anti-S(N)2'-type reduction of internal propargylic carbonates with hydrosilanes affords various di- and trisubstituted allenes with high regioselectivities; the reactions are compatible with functional groups and work efficiently for the synthesis of optically-active allenes.
