description: The precise range of contamination determines the cost of treating heavy metals contamination of soils at industrial sites and was a key aspect of soil heavy metals contamination management. The pollution level and spatial correlation of As, Cd, Cr, Cu, Hg, Ni, Pb and Zn in one hundred and thirty topsoil samples from a typical contaminated site was analysed. Geochemical analysis showed that Hg pollution was the most serious in the site, followed by Cd, Pb, Zn, Cu and Cr. The contents of As and Ni in the soil did not exceed the background values. The interpolation accuracy, interpolation results and spatial distribution of inverse distance weight method (IDW), local polynomial method (LPI), radial basis function method (RBF) and ordinary kriging method (OK) were compared, respectively. The results show that the range, mean and coefficient of variation of the four interpolation methods were generally lower than that of the sampled data, which was mainly caused by smoothing effect. The smoothing effect of LPI and OK were the most serious, while the smoothing effect of IDW and RBF were not obvious. The optimal interpolation method of Cd, Cr, Hg, Pb and Zn in polluted sites was RBF and the optimal interpolation method for As, Cu and Ni was IDW. The evaluation of polluted area by IDW and RBF interpolation method was ranked as IDW > RBF, which was much larger than that calculated by sampling point. Both interpolation methods could increased the area of polluted area. The probability kriging (PK) method was similar to that based on sampling points, which can greatly improve the calculation accuracy of heavy metals polluted area in industrial contaminated sites. Geochemical data and spatial interpolation results show that phytoremediation techniques was the most suitable for remediation of heavy metal contaminated soils at this site.

description: The application of eco-friendly, economically justifiable and reusable materials in removing pollutants from the aqueous solutions has received much attention. Therefore, in the present study, three adsorbents (carbon/aerogel (CA), carbon/aerogel/nickel (CAN) and carbon/aerogel/magnetite (CAM)) were used to remove diclofenac from the aqueous solutions. The various techniques such as brunauer-emmett-teller (BET), thermogravimetric (TGA), fourier transform infrared spectroscopy (FTIR) and X-ray photoelectron spectroscopy (XPS) were used to investigate the structure and main composition of the target adsorbents. The average size and specific surface area for CA, CAN and CAM adsorbents were obtained (6.5 nm and 714.93 m2 g−1), (1.61 nm and 734.32 m2 g−1) and (1.65 nm and 1193.9 m2 g−1), respectively. The maximum amount of the adsorbed pollutant on CA, CAN and CAM adsorbents were determined to be 60 mg g−1 (based on Sips), 101.9 mg g−1 (based on Langmuir) and 78 mg g−1 (based on Khan), respectively. The experimental data obtained for CA, CAN and CAM showed the best fit with Sips, Langmuir and Khan isotherms, respectively. In addition, the best kinetic models to express the adsorption characteristics of CA, CAN and CAM adsorbents were pseudo-first order, pseudo-first order and pseudo-second order, respectively. The performances of the CAN and CAM adsorbents were investigated for six consecutive cycles. The efficiency of CA, CAN and CAM adsorbents in diclofenac adsorption in the first and sixth cycles were (84% and 55%), (90% and 67%) and (88% and 63%), respectively.

description: A series of asymmetric isocyanidometal-bridged compounds cis-[Cp5(dppe)M(μ-CN)Ru(bpy)2(μ-NC)Ru(dppe)Cpx][PF6]2 (N2+[PF6]2: M = Fe and x = 0, N = 1; M = Fe and x = 1, N = 2; M = Ru and x = 0, N = 3; M = Ru and x = 1, N = 4. Cp0 = cyclopentadienly; Cp1 = 1-methyl-cyclopentadienly; Cp5 = 1,2,3,4,5-pentamethylcyclopentadienly, dppe = 1,2-bis(diphenylphosphino)ethane, bpy = 2,2′-bipyridine) were fully characterized. For the one- and two-electron oxidized states of N2+[PF6]2, N3+[PF6]3, and N4+[PF6]4, both their MMCT and electronic delocalization properties were investigated. The investigation results show that both the one-electron oxidized asymmetric Fe-Ru-Ru compounds 13+ and 23+ are localized, the charge being on the Fe centers. When the terminal Fe is substituted with Ru, the charge of 33+ is mainly delocalized between the Ru(2) and Ru(3) centers, while upon an addition of a methyl group on the terminal 1,3-cyclopentadienly ligand, the charge of 43+ is further delocalized into the Ru(1) center. Furthermore, for the two-electron oxidized asymmetric compounds 14+–44+, both the Fe-Ru-Ru and Ru-Ru-Ru series are highly delocalized.

description: This study assesses the first approach regarding the origin, level of contamination, and spatial and vertical distribution of aliphatic and polycyclic aromatic hydrocarbons in coastal sediments of Arica’s Bay. Twenty-seven aliphatic hydrocarbons (AHs) and eighteen polycyclic aromatic hydrocarbons (PAHs) were studied at three depths in sediment cores collected from six locations in the coastal bay. The spatial distribution pattern of the molecular composition of aliphatic and aromatic hydrocarbons is consistent with the directions of the ocean currents from the northeast to the southwest. PAHs are mainly correlated with anthropogenic input sources to the bay. The total aliphatic hydrocarbons showed a wide concentration range from 112.07 to 2,382.43 ng·g−1 dry wt. while total PAHs ranged from 8.01 to 85.40 ng·g−1 dry wt. The vertical distribution of the total AHs shows a tendency to concentrate between 10–20 and 20–30 cm depth. Specific diagnostic characterisation ratios suggest that the bay sediments mainly consist of a mixture of autochthonous, predominantly marine sources composed of marine bacteria (n-C16, n-C18, and C20) and terrestrial plant derivatives (n-C29 and n-C31) and with a contribution of petrogenic hydrocarbons masked by biogenic hydrocarbons. The vertical distribution of the total polycyclic aromatic hydrocarbons is dominated by low molecular weight (LMW) PAHs of two and three rings, such as fluoranthene (FLT), phenanthrene (PHE), pyrene (PYR), and the highest concentrations are found between 10 and 20 cm depth of the sediment column. The PAH diagnostic ratios revealed a mixture of pyrogenic hydrocarbons (biomass and coal combustion) with petrogenic compounds from the Port of Arica and its neighbouring areas. According to the guidelines of UNEP for AHs and PAHs categorisation, the bay’s sediments may be classified from harmless to harmful due to AHs composition and low PAHs pollution.

description: To investigate the dissipation, terminal residues, and dietary exposure risk of flonicamid, a field trial was conducted in China, and cabbage samples were determined by modified QuEChERS pretreatment and high performance liquid chromatography tandem mass spectrometry (HPLC-MS/MS). The method showed good linearity (R2 ≥ 0.99), the mean recoveries ranged from 97% to 103%, with the relative standard deviation (RSD) less than 1.5%, and the matrix effect (ME) was 5%. The field trial showed that the dissipation of flonicamid in Shanxi conformed to the first-order kinetic equation with a half-life of 2.2 days. The terminal residue results showed that the residues of flonicamid in cabbage were all lower than 0.12 mg/kg. The hazard quotient (HQ) and risk quotient (RQ) were applied to dietary exposure risk assessment based on terminal residue and toxicology data. The HQ of different populations ranged from 0.17 to 0.37, and the RQ was 81.4%, indicating low risk of dietary intake of flonicamid in cabbage.

description: We present the synthesis of Activated Carbon (AC) by pyrolysis of Banana (Musa Acuminate) Stem Waste (BSW), and the ability of obtained AC for adsorptive removal of Pb(II) ions from water. Importantly, pyrolysis was performed at 750°C for 2.0 h in the presence of high surface area producing chemical activators such as NaOH, LiOH, H3PO4, ZnCl2, and KOH. BET-surface areas of AC produced with activators NaOH, LiOH, H3PO4, ZnCl2, and KOH were determined to be 908, 1531, 1670, 2245, and 2485 m2 g−1, respectively. Pore volume ascending order was determined as 0.59 (NaOH) < 0.68 (LiOH) < 0.86 (H3PO4) < 0.97 (ZnCl2) <1.18 (KOH) cm3 g−1. SEM and TEM images revealed the porous nature of the ACs. ACs produced with H3PO4, ZnCl2, and KOH exhibit type I adsorption isotherms, indicating their microporous nature. ACs prepared with NaOH and LiOH exhibit type II adsorption isotherms, indicating their macroporous nature. X-ray diffraction, X-Ray photoelectron, and Raman spectroscopy analysis revealed the graphitic structure of ACs. Pb(II) ion adsorption onto ACs surface obeyed the Langmuir model. It was found that the Pb(II) adsorption capacities of the ACs produced with NaOH, LiOH, H3PO4, ZnCl2, and KOH as the chemical activators were 220, 283, 326, 329, and 435 mg g−1, respectively, at the optimised conditions (pH = 6.6, contact time = 100 min, [ACs] = 0.125 g L−1, at 30°C). The interaction between surface functional groups of ACs and Pb(II) ions was confirmed by X-Ray photoelectron and FT-Infrared spectroscopy. The negative values of ΔGo and ΔHo reveal that the Pb(II) ion adsorption onto the ACs surface is spontaneous and exothermic. The Pb(II) ion adsorption capacity increased with an increase in BET-SA and pore volume of ACs, with AC obtained from BSW with KOH exhibiting the highest adsorption capacity of 435 mg g−1. Thus, the study highlights BSW, agricultural biomass waste is a low-cost and abundantly available carbon precursor to synthesise potential AC adsorbent for water treatment.

description: We report on the preparation, crystal structure and spectral properties of the novel trimethylsulfonium tin tribromide, [(CH3)3S]SnBr3. The compound was synthesized by the solid-state reaction of (CH3)3SBr and SnBr2 in evacuated pyrex tubes at 150 °C. Single-crystal X-ray diffraction (SCXRD) studies at −173.15 °C show that it forms a 0D network of isolated pyramids of [SnBr3]− and (CH3)3S+ units in an orthorhombic structure (space group P212121, No. 19, a = 9.4508(8) Å, b = 14.1691(12) Å, c = 15.4409(14) Å)). Powder X-ray diffraction (PXRD) and Le bail profile fit analysis reveals that [(CH3)3S]SnBr3 adopts at room temperature a different crystal structure with space group (Pmmm, No. 47). Moreover, the oxidation of the compound occurs gradually in ambient air, towards the formation of [(CH3)3S)]2SnBr6 (space group Pa-3, No. 205). Multi-temperature Raman spectroscopy reveals that a fully reversible structural phase transition occurs for [(CH3)3S]SnBr3 between −36 and −56 °C, as evidenced by the changes in the vibrational modes of the [SnBr3]− ions. A direct band gap of 3.38 eV at RT is determined via UV–vis diffuse reflectance spectroscopy. Photoluminescence spectroscopy at −196.15 °C and 25 °C shows a weak luminescence signal with an emission maximum at ca. 460 nm for both temperatures.

Moreover, some antioxidant activities and radical scavenging properties of honey samples were investigated. The findings showed that the antioxidant properties of honey, which are strongly connected to their floral origins, have a significant therapeutic potential. While artificial radioactive 137Cs could not be detected in any of the honey samples, the average activity concentrations of natural radionuclides were 0.79 ± 0.23 Bq kg−1 for 226Ra, 0.85 ± 0.32 Bq kg−1 for 232Th and 68.33 ± 22.80 Bq kg−1 for 40K, respectively. The difference in 226Ra, 232Th, and 40K contents between honey species was not statistically significant (p>0.05). In addition, the lifetime cancer risk values calculated from honey consumption were found to be below the acceptable limit values.

description: The Bundelkhand region of Central India has been facing increasing severity of droughts, water-level depletion and deterioration in water quality. In this perspective, an attempt has been made for a qualitative evaluation of surface and groundwater resources belonging to the rural environment of this region to understand the contaminant’s source and probable human health risk due to the intake of the available water. The water samples collected from this region were analysed for pH, electrical conductivity (EC), total dissolved solids (TDS), turbidity, total hardness (TH), major anions (F−, Cl−, HCO3−, SO42−, NO3−) and major cations (Ca2+, Mg2+, Na+, K+). The observations revealed a near-neutral to slightly alkaline nature of the studied water samples. The computed water quality index implies that around 82% water samples are of good to excellent category for drinking uses. Turbidity, TDS, TH and NO3− were identified as the major parameters which violate the limits of drinking water. Geochemical investigations in association with multivariate statistical analysis identify carbonate weathering in coordination with the ion-exchange process as the major hydrogeochemical mechanism controlling the solute chemistry and concentrations of TH, TDS, HCO3−, F−, Ca2+, Mg2+ and Na+. On the contrary NO3−, Cl−, SO42− and K+ were strongly associated with anthropogenic activities. Water at most of the locations expresses positive saturation indices with respect to calcite and dolomite minerals, inferring the precipitation of these mineral phases. Sodium adsorption ratio (SAR) and percent sodium (%Na) values show a low alkali hazard and water can be used safely for irrigation purposes. However, high salinity in 39% of the water samples makes it unfit for application in agricultural fields. The non-carcinogenic hazard indices (HI) calculated by adding hazard quotient values of NO3− and F− for child, adult male and female population show that more than 64% of the water samples are deemed to be unfit for human consumption.

description: Using quantum chemical design within the framework of density functional theory in three versions, namely DFT M06/TZVP, DFT B3PW91/TZVP, and DFT OPBE/TZVP, the possibility of the existence of a new “nitrogen-rich” zinc chemical compound—dodecaazacyclododecatetraene-1,4,7,10, which contains the currently maximum number of nitrogen atoms per one zinc atom, equal to 12, was shown. Data on the structural parameters of this unusual compound and the macrocyclic ligand H4(N12), of which this compound is a derivative are presented. It was noted that the group of four nitrogen atoms bonded with a zinc atom, and group containing the same atoms in the H4N12 molecule, are non-coplanar with a relatively small amount in the case of ZnN12 (no more than 6°) and at the same time quite noticeable in the case of H4(N12) (about 23°) deviation from the plane; , . The nitrogen atoms forming a 12-membered macrocycle are generally not equivalent to each other; it has rather considerable deviation of N12 group from coplanarity (more than 60°). Good agreement was noted between the parameters of molecular structures of ZnN12 and H4N12 calculated using these various DFT versions. Standard thermodynamic parameters, NBO analysis data, and HOMO/LUMO images for this compound are also presented.

description: Los estudios sobre la temática multimedia en los últimos años han tenido un crecimiento sostenido a partir del desarrollo de las Tecnologías de la Información y las Comunicaciones. Existen pocas revistas especializadas para socializar la investigación sobre la temática multimedia. Se planteó como objetivo del estudio: identificar las publicaciones seriadas y científicas que abordan los estudios multimedia en habla hispana y caracterizarlas de acuerdo a aspectos editoriales. La sistematización de las publicaciones favorecerá que los investigadores que abordan la temática multimedia, identifiquen aquellas revistas a las que pueden enviar sus contribuciones. Para la obtención de resultados se emplearon métodos en los niveles teórico y empírico, fundamentalmente el análisis documental. Se realizó un directorio de revistas científicas que abordan la temática multimedia y se organizaron a partir de indicadores editoriales como fuentes de indización, área temática, país, dirección electrónica, institución de procedencia y frecuencia de publicación.
World Music and Activism Since the End of History

description: The decline of protest songs in the mainstream West since the 1970s has been oft noted, and has been traditionally related to specific developments such as the end of the Vietnam War. In this essay, I suggest that the decline was part of a much broader change in global culture, and that a cross-cultural exploration of the parallel trajectories of diverse political song movements can enrich our understanding of the global socio-political climate as a whole. I suggest that activist musical movements, in diverse parts of the world, illustrate with particular clarity how the 1950s-70s represented a sort of high point for a set of international socio-political movements which, although diverse, were animated by shared Enlightenment values of liberal secular humanism. Since the 1980s, however, the dissipation of these musical movements—and in many cases, their replacement by lyric expressions of militant, intolerant, chauvinistic neo-tribalisms—reflects the passing of this distinctive political historical moment, and its segue to a new era in global music culture and world history.

description: Four triorganotin (IV) complexes 1–4 [R = Bu (1 and 3) and Ph (2 and 4)] were synthesized from two azo-carboxylate ligands, namely 4-[(E)-2-(4-methoxy/methylphenyl)-1-diazenyl]-3-hydroxy-2-naphthoic acid by reacting with bis-tri-n-butyltin (IV) oxide (compounds 1 and 3) triphenyltin (IV) chloride (compound 2) and triphenyltin (IV) hydroxide (compound 4). The complexes were characterized using UV, IR, and NMR (1H, 13C, and 119Sn) spectroscopy. The geometry around Sn atoms in the complexes in the solution state was determined by NMR spectroscopy. The study indicates that all the compounds adopt tetrahedral structure in solution. The mode of coordination and crystal structure of 2 in the solid state was established by X ray crystallography, revealing monomeric, five-coordinated deformation structure, intermediate between square pyramidal and trigonal bipyramidal geometries. The antidiabetic activities of the synthesized compounds were evaluated and compound 2 was found to be effective.

description: In this study, we report the synthesis and characterization of a nickel(II) complex of p-tolylglyoxime. Its molecular structure was elucidated using FTIR, 1H NMR, elemental analysis, MALDI-TOF-MS, and single crystal X-ray diffraction (XRD). It was found that the complex crystallizes in the triclinic crystal system, space group P–1. In the crystal structure, intermolecular O—H···O, O—H···N and bifurcated C—H···O hydrogen bonds link the molecules into a three-dimensional network. Hirshfeld surface analysis revealed that the most significant contributions to the crystal packing arise from H … H (44.4%), H … O/O … H (20.1%) and H … C/C … H (16.6%) interactions, with hydrogen bonding and van der Waals interactions playing dominant roles. Crystal void analysis confirmed the absence of large cavities within structure. The assessment of the electrostatic, dispersion and total energy frameworks demonstrated that stabilization is dominated by dispersion energy contribution. The binding mode of complex was investigated through molecular docking studies with DNA and human serum albumin (HSA), revealing that the Ni(II) complex interacts with DNA via intercalation and binds to subdomain IB of HSA. Finally, an ADMET (Absorption, distribution, metabolism, excretion, and toxicity) study indicated that the pharmacokinetic properties of the complex are comparable to those of cisplatin.

description: Хотя этнографические режимы, отличные от письма, всегда существовали в антропологических исследованиях, в рамках дисциплины уже давно растет эпистемологическое напряжение между текстовыми и “иными методами” - использующими фотографии, движущиеся изображения, звук, рисунки, движение тела и т.д. Сторонники этих альтернативных методов практикуют то, что недавно было названо “мультимодальной антропологией”. В этой статье на примере музеев космоса я покажу, что в исследовании мультимодальные инструменты могут быть не только дополнительными, но и главными. Мультимодальные подходы к включенному наблюдению и документальному анализу помогают контекстуализировать знания, теории и опыт как антропологов, так и их собеседников. Такой коллаборативный опыт особенно важен в исследованиях, касающихся космоса и музеев. Музеи - мультимодальное поле, поскольку создание визуальных, тактильных и перформативных зрелищ для публики требует этнографических методов, выходящих за рамки письменных полевых заметок. В этом смысле космические музеи - лиминальное пространство для посетителей, которое должно вызывать особые ощущения и рефлексию о месте и цели человечества во Вселенной, о национальных победах в космосе и об освобождении от земного притяжения. Методологические процедуры, используемые в музеях космоса наряду с письмом, позволяют говорить о визуальных и перформативных антропологических подходах как о фундаментальном этнографическом ремесле.
