Year: 2021
Subjects: subject: Applications (stat.AP)

description: Functional magnetic resonance imaging (fMRI) is a non-invasive and in-vivo imaging technique essential for measuring brain activity. Functional connectivity is used to study associations between brain regions, either while study subjects perform tasks or during periods of rest. In this paper, we propose a rigorous definition of task-evoked functional connectivity at the population level (ptFC). Importantly, our proposed ptFC is interpretable in the context of task-fMRI studies. An algorithm for estimating the ptFC is provided. We present the performance of the proposed algorithm compared to existing functional connectivity frameworks using simulations. Lastly, we apply the proposed algorithm to estimate the ptFC in a motor-task study from the Human Connectome Project.

description: After the 1945 atomic bombings over Hiroshima and Nagasaki, the awareness of the two world super powers – USA-URSS – that conventional arm would have not been adequate anymore for political confrontation, led the two opposite blocks to the Cold War, fought almost exclusively on the basis of persuasion. Following WWII, the US, having to face the quick and unwanted unfolding of communism over the rubles and ruins of Europe, decided to organize their own propaganda machine to contrast the Soviet “soft power”. This paper intends to deal with the persuasive intent delivered by the US – with Shows, Exhibitions, International Fair and the help of the whole government apparatus – in order to convincingly popularize the advantages of their way of living throughout the world. It will be pointed out how, in cultural and anthropological terms, such initiatives led to the penetration of American culture, a sort of colonization, all over the world. An enormous endeavor of persuasion aimed to inform and convince that what the American way of life could secure to everybody would have been, amongst other things, a prosperous world of freedom, the best of all possible worlds.

description: The alignment strength of a graph matching is a quantity that gives the practitioner a measure of the correlation of the two graphs, and it can also give the practitioner a sense for whether the graph matching algorithm found the true matching. Unfortunately, when a graph matching algorithm fails to find the truth because of weak signal, there may be "phantom alignment strength" from meaningless matchings that, by random noise, have fewer disagreements than average (sometimes substantially fewer); this alignment strength may give the misleading appearance of significance. A practitioner needs to know what level of alignment strength may be phantom alignment strength and what level indicates that the graph matching algorithm obtained the true matching and is a meaningful measure of the graph correlation. The {\it Phantom Alignment Strength Conjecture} introduced here provides a principled and practical means to approach this issue. We provide empirical evidence for the conjecture, and explore its consequences.
A Window on the United States. The Image of American Architecture in West Germany’s Journals: 1947-1962

Publisher: name: Histories of Postwar Architecture

Subjects: Post-War Germany; Americanism; Architectural Journals; Baukunst und Werkform; Baumeister

description: This article aims to explore how American architecture was presented throughout the pages of two main architectural journals published in West Germany in the very first years after the end of World War II. The selected journals, Baukunst und Werkformand Baumeister, are rather independent magazines with opposite positions – the first is extremely oriented towards modernity and the latter is deeply conservative - and by no means can be considered as part of the cultural Cold War program. In spite of that, studying these magazines reveals how, in this particular period, it was impossible to avoid knowing, measuring and confronting the transatlantic world.

Resurrection of Antoni Gaudí in Post-War Media. A Critical Chronology. 1945-1965
Creators: name: Rodríguez Pedret, Carmen

Subjects: Gaudí; Architecture Magazines; Exhibitions; Films; Photography

description: The Post-War time coincides with the rehabilitation of Antoni Gaudí, a process closely linked to the spread of his architecture on a global scale. Although Gaudí’s historiography has paid specific attention to some outstanding episodes of this rehabilitation, these have not been shared from the outlook of the media apparatus that sustains them, following a temporal cadence that favours their relational reading from a critical perspective. The Post-War “resurrection” of Gaudí cannot be separated from the large number of publications, exhibitions, photographic series and even films that shaped his figure according to the interests of time: a media operation, not neutral at all, which explains, to a great extent, the treatment that the architect and his work still receive today.

description: This article emphasizes that effective classroom management is a vital part of teaching. A classroom that is well-managed creates an environment where students can learn and grow effectively. However, managing a classroom can be particularly challenging, especially for new teachers. Classroom management can be approached in different ways, and what works for one teacher may not work for another. Despite this, there are certain universal principles that can help all educators enhance their classroom management skills.
Spanish Post-War Architecture in Portuguese Magazines (1946 – 1970) – the cases of A Arquitectura Portuguesa & Cerâmica e Edificação (Reunidas) and Arquitectura

Subjects: Architectural Media Coverage; Spanish Post-War Architecture; Portuguese Post-War Architecture; Portuguese Architectural Magazines

description: The article deals with the publication of Spanish architecture in Portuguese mass-media during the post-war period. By focusing on two major titles, i.e. the A Arquitectura Portuguesa & Cerâmica e Edificação Reunidas and the Arquitectura magazines, the article traces the architectural, cultural, and political ties, but also the shifts, between the two Iberian countries, in a period that spans from the upsurge of the Spanish Civil War to the outbreak of the 1970s. In other words: from the raise of Franco to the death of Salazar. The article shows that, as early as January 1946, the new Spanish architecture was considered by Portuguese architectural magazines as a relevant subject, namely by the publication of the works authored by the Coderch and Valls team. Cumulatively, the article argues that this importance was linked to the long-lasting and well-documented relationship between Portuguese publishers and the Italian Domus magazine, made thru the patronage of Italian architect Gio Ponti.

Improved device-independent randomness expansion rates using two sided randomness

Publisher: name: arXiv

description: A device-independent randomness expansion protocol aims to take an initial random string and generate a longer one, where the security of the protocol does not rely on knowing the inner workings of the devices used to run it. In order to do so, the protocol tests that the devices violate a Bell inequality and one then needs to bound the amount of extractable randomness in terms of the observed violation. The entropy accumulation theorem lower bounds the extractable randomness of a protocol with many rounds in terms of the single-round von Neumann entropy of any strategy achieving the observed score. Tight bounds on the von Neumann entropy are known for the one-sided randomness (i.e., where the randomness from only one party is used) when using the Clauser-Horne-Shimony-Holt (CHSH) game. Here we investigate the possible improvement that could be gained using the two-sided randomness. We generate upper bounds on this randomness by attempting to find the optimal eavesdropping strategy, providing analytic formulae in two cases. We additionally compute lower bounds that outperform previous ones and can be made arbitrarily tight (at the expense of more computation time). These bounds get close to our upper bounds, and hence we conjecture that our upper bounds are tight. We also consider a modified protocol in which the input randomness is recycled. This modified protocol shows the possibility of rate gains of several orders of magnitude based on recent experimental parameters, making device-independent randomness expansion significantly more practical. It also enables the locality loophole to be closed while expanding randomness in a way that typical spot-checking protocols do not.

Female leadership in the HR function and the adoption of high-involvement HR practices
Creators: name: Li, Junting
Publisher: name: No Publisher Supplied
Year: 2024

description: Drawing on the upper echelons theory and research on gender leadership, this study proposes that the gender of chief HR officers (CHRO) can have an impact on the adoption of high-involvement HR practices. I specifically expect that female CHROs are more committed to the adoption of high-involvement HR practices because of their characteristics in their leadership styles, cognitive styles, and values, compared with male CHROs. While I propose that the direct effects of CHRO gender on the adoption of high-involvement HR practices are positive, the total effects of CHRO gender may also be conditioned by three organizational factors—the proportion of female top executives, the proportion of female middle managers and the level of financial slack. I test the research model using eight-wave panel data in South Korea from 2005 to 2019.

description: For $n\geq s> r\geq 1$ and $k\geq 2$, write $n \rightarrow (s)_{k}^r$ if every hyperedge colouring with $k$ colours of the complete $r$-uniform hypergraph on $n$ vertices has a monochromatic subset of size $s$. Improving upon previous results by \textcite{AGLM14} and \textcite{EHMR84} we show that \[ \text{if } r \geq 3 \text{ and } n \nrightarrow (s)_k^r \text{ then } 2^n \nrightarrow (s+1)_{k+3}^{r+1}. \] This yields an improvement for some of the known lower bounds on multicolour hypergraph Ramsey numbers.
 Given a hypergraph $H=(V,E)$, we consider the Ramsey-like problem of colouring all $r$-subsets of $V$ such that no hyperedge of size $\geq r+1$ is monochromatic. We provide upper and lower bounds on the number of colours necessary in terms of the chromatic number $χ(H)$. In particular we show that this number is $O(\log^{(r-1)} (r χ(H)) + r)$.

description: In many applications, solutions of convex optimization problems are updated on-line, as functions of time. In this paper, we consider parametric semidefinite programs, which are linear optimization problems in the semidefinite cone whose coefficients (input data) depend on a time parameter. We are interested in the geometry of the solution (output data) trajectory, defined as the set of solutions depending on the parameter. We propose an exhaustive description of the geometry of the solution trajectory. As our main result, we show that only six distinct behaviors can be observed at a neighborhood of a given point along the solution trajectory. Each possible behavior is then illustrated by an example.

description: Components of the static electric dipole polarizabilty (α), and second hyperpolarizability (γ) tensors have beendetermined by accurate ab initio calculations for three molecules containing two conjugated carbon – nitrogen and/or carbon – phosphorus triple bonds. For the NCCP molecule the dipole moment (μ) and non-vanishing components of the first hyperpolarizability (β) tensor have also been calculated. Electron correlation effects have been taken into account by the second-order Many Body Perturbation Theory (MBPT(2)), and coupled cluster (CCSD and CCSD(T)) calculations. The basis set developed by Sadlej (Pol) and designed to be used in electric properties calculations together with its extension (HyPol) have been applied and compared to the results obtained with the standard aug-cc-PVTZ sets of Dunning.

description: The role of connected triple excitations in coupled cluster CC calculations of vertical excitation energies, ionization potentials, and the electron affinity of the ozone molecule is evaluated. The equation of motion EOM and Fock space FS multireference CC approaches with full triples havebeen used in the calculations. The effect of the T3 and R3 operators significantly improve the EOM CCSD results for all considered quantities. A similar behavior is observed in the case of the FS-CC calculations. The FS-CC calculations with full triples have been obtained only for the intermediateHamiltonian realization of the FS approach as the standard formulation diverges. The latter results are rigorously linked, and less expensive since smaller matrices are diagonalized.

description: The concentration of elements in sediments is an important aspect of the quality of water ecosystems. The element concentrations in bottom sediments from Goczalkowice Reservoir, Poland, were investigated to determine the levels, accumulation and distribution of elements; to understand the contamination and potential toxicity of elements; and to trace the possible source of pollution. Sediments were collected from 8 sampling points. The functional speciation, mobility and bioavailability of elements were evaluated by means of modified Tessier sequential extraction. The element contents were measured by optical emission spectrometry with inductively coupledplasma. The experimental results were analyzed using chemometric methods such as principal component analysis and cluster analysis to elucidate the metal distributions, correlations and associations. The highest concentrations of most elements were found at the centerof the reservoir. The distribution of metals in the individual fractions was varied. To assess the extent of anthropogenic impact indices contamination factor, degree of contamination, metal pollution index and risk assessment code were applied. The calculated factorsshowed the highest contamination factor and the ability of chromium to be released from sediments. The degree of contamination showed that the area is characterized by a very high contamination. Strontium and manganese showed high potential ecological risk for sediments.

description: In this paper, we present a control-design method based on the energy-Casimir method for infinite-dimensional, boundary-actuated port-Hamiltonian systems with two-dimensional spatial domain and second-order Hamiltonian. The resulting control law depends on distributed system states that cannot be measured, and therefore, we additionally design an infinite-dimensional observer by exploiting the port-Hamiltonian system representation. A Kirchhoff-Love plate serves as an example in order to demonstrate the proposed approaches.

description: The molecule of the title compound (systematic name:6-chloroindolin-2-one), C8H6ClNO, is almost planar, with adihedral angle of 1.13 (9) between the planes of theconstituent pyrrolidine and benzene rings. Centrosymmetricdimers are formed in the crystal structure by N—H Ohydrogen bonds, and these dimers are additionally linked byCl Cl and C—H O interactions. Density functional theory(DFT) calculations at the B3LYP/6-31 G(d,p) level of theorywere used to optimize the molecular structure and thegeometry was best reproduced by optimization of twointeracting molecules. The bond orders in the molecule,estimated using the natural bond orbitals (NBO) formalism,are consistent with the observed bond lengths. In particular,the contribution of the lone pair of electrons on the N atom tothe N—C bond in the N—C O group is revealed. Themeasured IR spectrum of the compound shows a red shift ofthe N—H stretching frequency compared with the freemolecule, due to the formation of the hydrogen bonds.

description: Elements that enter the aquatic environment may pose a health risk to wildlife and humans. The aims of this study were: to determine how the introduction of activated carbon for a water purification system will improve the quality of the water produced; and to investigate the sorption of metals on activated carbons, including determination of the accumulation, as well as changes in concentrations of elements in carbons. The tests were carried out on three types of activated carbons with different granular structure. All samples were collected from Water Treatment Plant Goczalkowice, Poland. Concentrations of elements were measured using an optical emission spectrometer with inductively coupled plasma. The experiment showed that metals accumulating in the activated carbons during the operation included: Ca, Mn, Zn, and Cu. In each of the three types of carbons, it can distinguish such elements as Ba, Al, Cr, Ni, Ti, which are characterized by irregular accumulation during the operation of the filter. The introduction of carbon sorbent for water treatment largely contributed to improvement in the quality of raw material supplied to customers, mainly with regard to taste and smell, as well as to reduction of basic parameters: color, absorbance in the UV range and oxidability.

description: In the study, arsenic, antimony, and chromium concentrations and selected physicochemical parameters in water and sediment samples from the thermal anthroporessure subjected Rybnik Reservoir (Poland) were determined. As(III), As(V), Sb(III), and Sb(V) ions were successfully separated on Dionex IonPac AS7 column, and Cr(III) and Cr(VI) on Dionex IonPac AG7 column. The obtained limits of detection were 0.18, 0.22, 0.009, 0.012, 0.11, and 0.17 μg/L, respectively. Water and bottom sediment samples were collected monthly at three-point transect between January and November 2013. The As(III) and Sb(III) speciation forms dominated in the bottom water, and Cr(VI) concentration in the bottom water was twice as high as the value measured for the surface water. The oxidized arsenic, antimony, and chromium formsdominated in the bottom sediments in the heated water discharge zone of the Rybnik Power Plant. The location of sampling point had a significant influence on the observed transformations and contents of the analyzed speciation forms. The chemometric analysis coupled with the dissimilarity analysis and principal component analysis helped to visualize the variability in the concentrations of the element speciation forms within the researched period and analyzing correlations.

description: Hydroxytriphenylmethane dyes are organic compounds whose properties suggest a potential use innonlinear optics. They are also widely used in chemical analysis. The most commonly used is C.I.Mordant Blue 29. However, in the literature there are no complete spectroscopic characteristics of thedye and there is a lack of detailed information on the electrical properties of C.I. Mordant Blue 29 dye.The optimum geometry of C.I. Mordant Blue 29 was determined by minimizing the energy with respectto all geometrical parameters without imposing molecular symmetry constraints. The UV-VIS spectra ofC.I. Mordant Blue 29 and its charged species were computed with time-dependent density functionaltheory (TDDFT) by employing the B3LYP functional together with the 6-31++G(d,p) basis set atoptimized geometries. The calculations of UV-VIS spectra also considered the presence of a solvent interms of the polarized continuum model (PCM). The calculated spectra were compared with thoseobtained experimentally. The dipole moment (m), polarizability (a), and first hyperpolarizability (b) of C.I.Mordant Blue 29 were calculated using the time-dependent Hartree–Fock method, and the electron correlationcontribution to the electric properties was introduced by DFT using the functionals B3LYP,PBE0, and HCTH. Calculations were performed using several basis sets from 6-31G to 6-311++G(d,p).

description: Over the years, an enormous effort has been made to establish nitrogen vacancy (NV) centers in diamond as easily accessible and precise magnetic field sensors. However, most of their sensing protocols rely on the application of bias magnetic fields, preventing their usage in zero- or low-field experiments. We overcome this limitation by exploiting the full spin $S=1$ nature of the NV center, allowing us to detect nuclear spin signals at zero- and low-field with a linearly polarized microwave field. As conventional dynamical decoupling protocols fail in this regime, we develop new robust pulse sequences and optimized pulse pairs, which allow us to sense temperature and weak AC magnetic fields and achieve an efficient decoupling from environmental noise. Our work allows for much broader and simpler applications of NV centers as magnetic field sensors in the zero- and low-field regime and can be further extended to three-level systems in ions and atoms.

description: The extent of removal of pharmaceuticals by African-based wastewater treatment plants (WWTPs) is relatively unknown with various studies observing high concentrations in effluents. This is mainly due to WWTPs still utilising the traditional treatment methods which are known to be less effective. In this study, 15 selected antibiotics (amoxicillin, ampicillin, azithromycin, ciprofloxacin, doxycycline, erythromycin, gentamicin, metronidazole, norfloxacin, ofloxacin, penicillin, sulfamethoxazole, sulfapyridine, tetracycline and trimethoprim) were monitored in wastewater as it goes through sedimentation (primary and secondary), aeration and chlorination stages of a WWTP. Analytical method involved solid-phase extraction followed by liquid chromatographic determination. Removal efficiencies during sedimentation were generally positive with doxycycline achieving 80–95.8%, while negative removal efficiencies were observed for penicillin V (−46.4 to −17.1%) and trimethoprim (−26.2 to −18.9%). The aeration and agitation stage resulted in concentration enhancement for several antibiotics with seven of them ranging between −273 and −15.5%. This stage was responsible for the relatively low overall removal efficiencies in which only 4 antibiotics (doxycycline, tetracycline, ciprofloxacin, and erythromycin) experienced overall removal efficiencies above 50%. The recorded effluent concentrations ranging between 0.0130 and 0.383 ng/mL were translated to low potential for development of antibiotic resistance genes in the receiving environments while ecotoxicity risk was high for only amoxicillin, ampicillin and sulfapyridine. The study has provided an overview of the performance of common wastewater treatment processes in South Africa and hopes that more monitoring and environmental risk data can be made available towards drafting of antibiotic priority lists that cater for Africa.

description: We analyse the dynamical evolution of a fluid with non-linear drag, for which binary collisions are elastic, described at the kinetic level by the Enskog-Fokker-Planck equation. This model system, rooted in the theory of non-linear Brownian motion, displays a really complex behaviour when quenched to low temperatures. Its glassy response is controlled by a long-lived non-equilibrium state, independent of the degree of non-linearity and also of the Brownian-Brownian collisions rate. The latter property entails that this behaviour persists in the collisionless case, where the fluid is described by the non-linear Fokker-Planck equation. The observed response, which includes non-exponential, algebraic, relaxation and strong memory effects, presents scaling properties: the time evolution of the temperature -- for both relaxation and memory effects -- falls onto a master curve, regardless of the details of the experiment. To account for the observed behaviour in simulations, it is necessary to develop an extended Sonine approximation for the kinetic equation -- which considers not only the fourth cumulant but also the sixth one.

description: The aim of this work was to determine gallium contents in different soils of Poland using a sensitive spectrophotometric method based on the complex of Ga(III) with chromeazurol S and benzyldodecyldimethylammonium bromide and inductively coupled plasma–optical emission spectrometry technique. The total content of gallium in the soils clearly depends on the soil location and properties and ranged from 41.7 to 437 μg g–1. The contents of gallium determined in 10% nitric acid and 1 M of magnesium chloride extract ranges respectively from 38.0 to 81.9% and 20–40% of the total content of this element. A strong correlation has been found between gallium and zinc, cadmium, lead, and copper. The high Pearson correlation coefficient values and the proportional relationship between the concentrations of Ga and these metals may make it possible to treat gallium as an indicator of soil contamination with heavy metals.

description: We introduce ACES, a method for scalable noise metrology of quantum circuits that stands for Averaged Circuit Eigenvalue Sampling. It simultaneously estimates the individual error rates of all the gates in collections of quantum circuits, and can even account for space and time correlations between these gates. ACES strictly generalizes randomized benchmarking (RB), interleaved RB, simultaneous RB, and several other related techniques. However, ACES provides much more information and provably works under strictly weaker assumptions than these techniques. Finally, ACES is extremely scalable: we demonstrate with numerical simulations that it simultaneously and precisely estimates all the Pauli error rates on every gate and measurement in a 100 qubit quantum device using fewer than 20 relatively shallow Clifford circuits and an experimentally feasible number of samples. By learning the detailed gate errors for large quantum devices, ACES opens new possibilities for error mitigation, bespoke quantum error correcting codes and decoders, customized compilers, and more.

description: Immobilized microorganisms technology has been explored as a promising wastewater treatment method. To further increase the activity of the immobilized microorganisms, a porous membrane which was composed of poly (lactic acid) (PLA) and poly (ethylene glycol) (PEG) was designed for microorganism encapsulation. The plane membrane and the spherical membrane were prepared respectively. The morphology, mechanical properties, nitrate permeability, and biodegradability of the plane membranes were investigated to determine an optimized formulation. And then, denitrifying bacteria was encapsulated by the spherical membrane and its denitrification performance in synthetic wastewater was explored. The mean pore size of the PLA/PEG plane membranes ranged from 2.09 ± 0.63 μm to 3.15 ± 1.32 μm. PEG stimulated interconnected pore structure of the PLA/PEG plane membrane. Compare with neat PLA membrane, the tensile strength of the PLA/50%PEG plane membrane decreased by about 53.2% and elongation at break increased by about 103.5%. Nitrate permeability attained a maximum of 188.95 ± 4.59 mg·L−1·m−2·h−1 for PLA/50%PEG plane membrane. The denitrifying active sludge enclosed with the spherical membrane showed good denitrification performance in a short start-up time. The nitrate removal rate reached 51.14% on the 4th day and 82.53% on the 17th day. This porous PLA/50%PEG membrane was good for the diffusion of substrates and nutrients, which enabled the encapsulated microorganism recovered activity in a short time. The spraying method made the microorganism encapsulation could be designed according to the different microorganisms and different user environments, which expanded the application scope of microorganism encapsulation technology.

description: Given the Fourier-Legendre expansions of $f$ and $g$, and mild conditions on $f$ and $g$, we derive the Fourier-Legendre expansion of their product in terms of their corresponding Fourier-Legendre coefficients. In this way, expansions of whole number powers of $f$ may be obtained. We establish upper bounds on rates of convergence. We then employ these expansions to solve semi-analytically a class of nonlinear PDEs with a polynomial nonlinearity of degree 2. The obtained numerical results illustrate the efficiency and performance accuracy of this Fourier-Legendre based solution methodology for solving an important class of nonlinear PDEs.

Steady state in strong system-bath coupling: mean force Gibbs state versus reaction coordinate

description: Motivated by the growing importance of strong system-bath coupling in several branches of quantum information and related technological applications, we analyze and compare two strategies currently used to obtain (approximately) steady states in strong coupling. The first strategy is based on perturbative expansions while the second one uses reaction coordinate mapping. Focusing on the widely used spin-boson model, we show that, as expected and hoped, the predictions of these two strategies coincide for some parameter regions. This confirms and strengthens the relevance of both techniques. Beyond that, it is also crucial to know precisely their respective range of validity. In that perspective, thanks to their different limitations, we use one to benchmark the other. We introduce and successfully test some very simple validity criteria for both strategies, bringing some answers to the question of the validity range.

description: Inspired by the conventional pooling layers in convolutional neural networks, many recent works in the field of graph machine learning have introduced pooling operators to reduce the size of graphs. The great variety in the literature stems from the many possible strategies for coarsening a graph, which may depend on different assumptions on the graph structure or the specific downstream task. In this paper we propose a formal characterization of graph pooling based on three main operations, called selection, reduction, and connection, with the goal of unifying the literature under a common framework. Following this formalization, we introduce a taxonomy of pooling operators and categorize more than thirty pooling methods proposed in recent literature. We propose criteria to evaluate the performance of a pooling operator and use them to investigate and contrast the behavior of different classes of the taxonomy on a variety of tasks.

description: This study investigated the electrooxidation (EO) of mature landfill leachate from the Brady Road Resource Management Facility, Winnipeg (Canada). EO using boron-doped diamond (BDD) electrodes were applied to treat real landfill leachate using a batch reactor. Response surface methodology (RSM) was used to determine the optimum process parameter levels. This research mainly focused on how different current densities (64, 95, and 125 mA/cm2) and operational time (30 min, 1, 1.5, 2, 2.5, and 3 hr.) influenced the optimisation of parameters such as chemical oxygen demand (COD), colour, ammonium, and phosphate removal in mature landfill leachate at varied pH. To attain a high percentage of removal for the parameters mentioned above, the optimal conditions were found to be a current density (J) of 125 mA/cm2 and a pH of 8. The optimum conditions resulted in removal percentages of 95.47%, 80.27%, 71.15%, and 47.15% for colour, NH4+, COD, and PO43- respectively, with an energy consumption of 0.05 kWh/dm3. The removal is related to a mechanism of the decomposition of water molecules to hydroxyl radicals and by direct anodic oxidation where the pollutants are transformed to CO2 and H2O. The novelty of this research lies in the optimisation of BDD electrode-based treatment for the simultaneous removal of COD, ammonium, phosphate, and colour from mature leachate collected from a severely cold climatic region of Canada. The BDD electrode showed excellent removal efficiencies for the targeted contaminants with lower energy consumption, making it a feasible method for on-site landfill leachate treatment.

description: Interactions of the anionic form of C.I. Mordant Blue 29 with cationic and nonionic surfactants have been studied byabsorption spectroscopy. The dye interacts strongly with oppositely charged surfactants in the pre-micellar concentration range with an accompanying change in its spectral properties, while its interaction with the polyoxyethylene group of nonionic surfactants does not have such remarkable effects. In ternary mixtures, however, the influence of the polyoxyethylene group on the optical properties of C.I. Mordant Blue 29 tetradecyltrimethylammonium bromide and C.I.Mordant Blue 29-octadecyltrimethylammonium chloride systems is quite different. In addition, the influence of theinteraction between the HL3– form of C.I. Mordant Blue 29 and the surfactants on the formation of chelate complexes with iron(III) has been studied. The optimized structures of Fe-Mordant Blue 29 complexes are also reported herein.Geometries have been calculated by the Hartree–Fock method with the cc-pVDZ basis set.
