Dibutyl phthalate (DBP) and di-2-ethylhexyl phthalate (DOP) were chosen for comparison with Oxal.

Most studies have shown that potentially harmful trace elements emitted during coal combustion are distributed in bottom ash, fly ash particles of different parameters and flue gases so that they can reach soil and water.7 Content of heavy metals salts, such as chlorides or sulfates, affect leaching mechanisms of potentially harmful compounds in FAs.8,9 Ca and Mg are the most dominant cations in fly ash water leachates, while anions primarily include sulfates, carbonates and fluorides.10 The same method was used for the collection of coal fly ashes from TPKb (AKb), TPKs (AKs), TPNT (ANT) and from the cyclone of FBB (AFB). keywords: afb; akb; aks; analysis; ant; ashes; coal; combustion; content; elements; fas; fly; health; pahs; risk; trace cache: jscs-12208.pdf plain text: jscs-12208.txt item: #67 of 344 id: jscs-12228 author: Andrejić, Gordana; Kovačević, Milijana; Dželetović, Željko; Aleksić, Uroš; Grdović, Isidor; Rakić, Tamara title: Potentially toxic element accumulation in two Equisetum species spontaneously grown in the flotation tailings date: 2023-07-25 words: 4846 flesch: 52 summary: FET, E. telmateia flotation tailings substrate) was composed of well mixed substrate samples collected from the rhizosphere of 15 individuals.

Case studies of rapid well clogging under over-exploit- ation conditions were presented in the USA,1 Germany2 and France.3 An unsuit- able pumping scheme produces a general decline in the groundwater levels and disturbs the geochemical conditions of the initial system.3 Under such conditions, anoxic groundwater become oxidized, while the groundwater composition and microbial ecology are changed.3,4 Based on the chemical analyses of the groundwater samples, a study of data derived from microbiological analyses and assessments of the data on the static and dynamic groundwater levels inside the wells, the Trnovče source was charac- terized as an alluvial setting where oxic and anoxic ground waters blend.5,6 High concentrations of dissolved oxygen in the upper, water unsaturated part, of the aquifer and the inflow of anoxic groundwater featuring elevated iron concentra- tions from deeper, saturated parts of the aquifer have created a redox front within the well screens (Fig. 1), leading to a thorough precipitation of iron-(hydr)ox- ides.6 The conditions that lead to the formation of ferric deposits in water wells were analyzed in this study. keywords: aquifer; bacteria; chemical; clogging; groundwater; iron; oxidation; oxygen; rate; screen; source; supply; trnovče; wells cache: jscs-1525.pdf plain text: jscs-1525.txt item: #106 of 344 id: jscs-1528 author: HEJAZI, SEYYEDEH ZOHA; SHOJAEI, ABDOLLAH FALLAH; TABATABAEIAN, KHALIL; SHIRINI, FARHAD title: Preparation and characterization of ZrO2-supported Fe3O4-MNPs as an effective and reusable superparamagnetic catalyst for the Friedländer synthesis of quinoline derivatives date: 2015-09-01 words: 5423 flesch: 60 summary: O.

In a previous study, the residual monomer content and water sorption for PMMA denture base materials modified with dimethyl itaconate and dibutyl ita- conate were investigated.35 It was shown that the addition of itaconate led to a reduction in the water uptake and greatly reduced the residual methyl metha- crylate content. keywords: absorption; acid; base; content; denture; denture base; diffusion; dthfi; fig; itaconate; materials; monomer; pmma; properties; samples; values; water cache: jscs-1546.pdf plain text: jscs-1546.txt item: #123 of 344 id: jscs-1547 author: LAZAREVIĆ, SLAVICA S.; JANKOVIĆ-ČASTVAN, IVONA M.; JOKIĆ, BOJAN M.; JANAĆKOVIĆ, DJORDJE T.; PETROVIĆ, RADA D. title: The use in grass production of clinoptilolite as an ammonia adsorbent and a nitrogen carrier date: 2015-10-01 words: 3930 flesch: 52 summary: The mic- rographs of natural sepiolite sample showed the fibres had needle morphology of 30–50 nm in diameter and 1 μm in length.

Lite- rature reports on the analysis of herbicide residues from soil samples, using DM- SPME of a soil organic extract obtained by L–S extraction of previously diluted samples is a more efficient method than direct immersion of the SPME fiber in the slurry of soil sample and water.10–15 Previous study, based on the combination of conventional L–S procedure followed by DM-SPME determination of the sel- ected herbicides, showed that among different solvents tested (water, hexane, acetonitrile, acetone and methanol), two successive extractions with methanol (Met) as the extraction solvent seemed to be the optimal sample preparation choice.13 keywords: determination; extraction; fiber; herbicides; methanol; method; microextraction; preparation; results; sample; soil; spme; temperature cache: jscs-1760.pdf plain text: jscs-1760.txt item: #141 of 344 id: jscs-1765 author: Yang, Xuepeng; Yan, Ji; Wang, Fangfang; Xu, Jia; Liu, Xiangzhen; Ma, Ke; Hu, Xiangmei; Ye, Jianbin title: Comparison of organics and heavy metals acute toxicities to Vibrio fischeri date: 2016-07-22 words: 3953 flesch: 56 summary: However, the differ- ences of metals and organics acute toxicities to V. fischeri have not been com- pared.

In many studies the inhibitory effect of phenolics to oxidative damage, which could lead to athero- sclerosis and cancer, were reported.6–8 The antioxidant activity of phenolic com- pounds can be explained by several possible mechanisms, such as their ability to chelate metals, inhibit lipoxygenase, modulate peroxide concentration, scavenge free radicals and stimulate the enzyme systems of antioxidative defense.9 Due to harmful properties of synthetic antioxidants, such as butylated hydroxyanisole (BHA) and hydroxytoluene (BHT),10 demands of the food industry for antioxid- ants of natural origin, especially from industrial residues, have never been greater.11–13 Phenolic acids are one of the main classes of phenolics and, according to their chemical structure, represent derivatives of benzoic and cinnamic acids. keywords: acids; analysis; day; food; kernel; leaves; maize; method; sci; white cache: jscs-2955.pdf plain text: jscs-2955.txt item: #178 of 344 id: jscs-2957 author: Mendoza-Huizar, Luis Humberto; Salgado-Morán, Guillermo; Cardona-Villada, Wilson; Pacheco, Alison Geraldo; Glossman-Mitnik, Daniel title: A DFT study of the chemical reactivity of cimetidine A, C and D in the gas phase and in H2O, MeOH and EtOH solvents date: 2017-02-03 words: 5433 flesch: 59 summary: Thus, the obtained results suggest that either suspensions or solutions based on CimC and CimD may become more nucleophilic than those based on CimA, and thus, they might have better antiulcer drug behaviors than CimA suspensions.

Using O2 in subcritical water medium offers a powerful and eco- -friendly method that is widely used in the water recycling process and other environmental treatments.29,30 Dissolving oxygen in subcritical water initiates the formation of hydroxyl and other reactive radicals that participate in the react- ion process, thereby increasing the degradation degree.31 Degradation experiments were realized at four selected temperatures, spe- cifically at 373, 393, 413 and 433 K, as demonstrated in Table II. keywords: degradation; min; paracetamol; solubility; t t; temperature; time; water cache: jscs-3018.pdf plain text: jscs-3018.txt item: #181 of 344 id: jscs-3035 author: Bedda, Kahina; Hamada, Boudjema; Kuzichkin, Nikolay V.; Semikin, Kirill V. title: Extractive purification of hydro-treated gas oil with N-methylpyrrolidone date: 2017-02-03 words: 4528 flesch: 50 summary: The gas oil hydro-treating process is a catalytic process in which gas oil obtained from either primary distillation of crude oil or conversion processes (visbreaking, coking and catalytic cracking) is treated under hydrogen pres- sure.6,7 This process helps obtain a quality diesel fuel with low contents of sul- phur, nitrogen and aromatics together with a better stability and a high cetane number.1,5–7 This result was obtained for the extractive desulphurization of different types of gas oil using DMF, DMA and NMP. keywords: content; desulphurization; extraction; gas; gas oil; hydro; nmp; oil; raffinate; solvent; sulphur cache: jscs-3035.pdf plain text: jscs-3035.txt item: #182 of 344 id: jscs-3094 author: Padhy, Gopal K; Panda, Jagadeesh; Behera, Ajaya K title: Synthesis and characterization of novel benzimidazole embedded 1,3,5-trisubstituted pyrazolines as antimicrobial agents date: 2017-09-30 words: 4175 flesch: 58 summary: S.

The firing temperature of pottery samples classified as Vinča culture excavated on the territory of Romania at the archaeological site Limba, Alba County, was estimated at about 700 °C, and for only a few samples at 850–900 °C.12 Two samples from Vinča culture uncovered on the territory of Serbia were investigated as a part of a wider study of Neolithic–Bronze age pot- tery from Central and South–East Europe and the estimated firing temperatures were below 800 °C for the majority of the pottery made from non-calcareous clay and in particular, 750 °C for a sample from the Gomolava excavation site and between 800–850 °C for a sample from the Vinča excavation site.18 That finding is in excellent agreement with a study of comparable pottery from Karanova in Bulgaria, with an estimated firing temperature of less than about 750 °C.19 Fig. keywords: black; clay; cm–1; decorations; fig; firing; ftir; pottery; samples; spectra; temperature; vinča; white cache: jscs-3653.pdf plain text: jscs-3653.txt item: #193 of 344 id: jscs-3659 author: Božinović, Nina; Šolaja, Bogdan A.; Opsenica, Igor A. title: Microwave-assisted synthesis of azepines via nucleophilic aromatic substitution date: 2016-11-26 words: 2693 flesch: 55 summary: B.

A comparison among the activation energies and reaction energies for the I-DA reaction of 1 with 2a in Table II and Table S-II of the Supplementary material indicated that the meta pathways with extremely high potential energies should be ignored and thus attention was focused on the ortho pathways of these reactions. Moreover, the stepwise pathways were investigated in I-DA reaction of 4-chlorostyrene and 4-methylstyrene (2b and 2c, respectively) with aryl oxonium ion 1 (Scheme 2) along the more favored pathways (ortho ones), and the results of their activation energies and reaction energies, given in Table II, indicated that the ortho-endo pathways are the more favorable ones. keywords: chem; endo; energies; exo; mechanism; mol–1; ortho; pathways; reaction; stepwise; styrene cache: jscs-378.pdf plain text: jscs-378.txt item: #198 of 344 id: jscs-3866 author: Satheesh, Sandhya Vyjayanthy; Radha, Akhila Vijayan; Girija, Krishnapriya Krishnan Nair; Rajasekharan, Kallikat Narayanan; Maheswari, Priya Rani title: Hindered phenolic aminothiazoles – Synthesis, α-glucosidase and α-amylase inhibitory and antioxidant activities date: 2017-11-04 words: 4520 flesch: 57 summary: Thus, [4-amino-2-(phenylamino)-5-thiazolyl](3,5-di-t-butyl-4-hydroxyphenyl)- methanone exhibited α-glucosidase inhibition activity with an IC50 value of 117 µM while the standard compound acarbose showed an IC50 value of 48.3 µM and {4-amino-2-[(4-methylphenyl)amino]-5-thiazolyl}(3,5-di-t-butyl-4- -hydroxyphenyl)methanone showed good α-amylase inhibition activity with an IC50 value of 283 µM compared to acarbose (IC50 532 µM).

Ethanol was removed from the dispersions by rotary evaporation (Rotavapor R300, Büchi, Switzerland), and thereby aqueous dispersions of zein nanoparticles were obtained. keywords: carvacrol; ethanol; fig; mass; nanoparticles; ratio; rosin; rosin nanoparticles; shellac; size; solutions; tween; water; zein cache: jscs-8030.pdf plain text: jscs-8030.txt item: #313 of 344 id: jscs-8039 author: Borota, Ana; Avram, Sorin; Curpan, Ramona; Bora, Alina; Varga, Daniela; Halip, Liliana; Crisan, Luminita title: In silico studies on smoothened human receptor and its antagonists in search of anticancer effects date: 2020-03-30 words: 5214 flesch: 54 summary: R.

Effect of temperature on the electrical conductivity of DESs The experimental electrical conductivity values, as well as the additional considerations, are presented in Tables S-III–S-XI. The physical properties, such as density, viscosity, electrical conductivity and refractive index, could provide essential information on the purity of samples and the molecular interactions in the liquid, which will be useful for the design of the contacting equipment and modeling of the process.14 In this study, the physicochemical (density, viscosity, electrical conductivity, refractive index, thermal expansion coefficient, molecular volume, lattice energy, and heat capacity) properties of different DESs of TEOA as hydrogen bond acceptor (HBA) and oxalic acid (OA), glacial acetic acid (AA), L-(+)-lactic acid (LA), oleic acid (OLA), glycerol (G), ethylene glycol (EG), propylene glycol (PEG), ChCl or 1,3-dimethylurea (DMU) as HBDs were measured in the tempe- rature range of 293.15–363.15 K at 101.325 kPa for the first time. keywords: chcl; conductivity; density; dess; dmu; index; ola; peg; range; temperature; teoa; viscosity cache: jscs-9455.pdf plain text: jscs-9455.txt item: #334 of 344 id: jscs-9486 author: Berjis, Anita; Mirza, Behroox; Anaraki-Ardakani, Hossein title: Green and efficient synthesis of new β-amido-aroyl carbonyl derivatives catalyzed by choline chloride/urea as a deep eutectic solvent: Scientific paper date: 2021-06-29 words: 3308 flesch: 57 summary: B.
