Persistent homology analysis of multiqubit entanglement
Authors: Mengoni Ricardo , Di Pierro Alessandra , Memarzadeh Leleh , Mancini Stefano
Published: February 2021

We introduce a homology-based technique for the classification of multiqubit state vectors with genuine entanglement. In our approach, we associate state vectors to data sets by introducing a metric-like measure in terms of bipartite entanglement, and investigate the persistence of homologies at different scales. This leads to a novel classification of multiqubit entanglement. The relative occurrence frequency of various classes of entangled states is also shown.
Quantum unsupervised and supervised learning on superconducting processors
Authors: Sarma Abhijat , Chatterjee Rupak , Gili Kaitlin , Yu Ting
Published: February 2021

Machine learning algorithms perform well on identifying patterns in many different datasets due to their versatility. However, as one increases the size of the data, the computation time for training and using these statistical models grows quickly. Here, we propose and implement on the IBMQ a quantum analogue to K-means clustering, and compare it to a previously developed quantum support vector machine. We find the algorithm's accuracy comparable to the classical K-means algorithm for clustering and classification problems, and find that it becomes less computationally expensive to implement for large datasets as compared to its classical counterpart.
Quantum coherence, discord and correlation measures based on Tsallis relative entropy
Authors: Vershynina Anna
Published: February 2021

Several ways have been proposed in the literature to define a coherence measure based on Tsallis relative entropy. One of them is defined as a distance between a state and a set of incoherent states with Tsallis relative entropy taken as a distance measure. Unfortunately, this measure does not satisfy the required strong monotonicity, but a modification of this coherence has been proposed that does. We introduce three new Tsallis coherence measures coming from a more general definition that also satisfy the strong monotonicity, and compare all five definitions between each other. Using three coherence measures that we discuss, one can also define a discord. Two of these have been used in the literature, and another one is new. We also discuss two correlation measures based on Tsallis relative entropy. We provide explicit expressions for all three discord and two correlation measure on pure states. Lastly, we provide tight upper and lower bounds on two discord and correlations measures on any quantum state, with the condition for equality.
CNOT circuit extraction for topologically-constrained quantum memories
Authors: Kissinger Aleks , van de Griend Arianne Meijer
Published: February 2021

Many physical implementations of quantum computers impose stringent memory constraints in which 2-qubit operations can only be performed between qubits which are nearest neighbours in a lattice or graph structure. Hence, before a computation can be run on such a device, it must be mapped onto the physical architecture. That is, logical qubits must be assigned physical locations in the quantum memory, and the circuit must be replaced by an equivalent one containing only operations between nearest neighbours. In this paper, we give a new technique for quantum circuit mapping (a.k.a. routing), based on Gaussian elimination constrained to certain optimal spanning trees called Steiner trees. We give a reference implementation of the technique for CNOT circuits and show that it significantly out-performs general-purpose routines on CNOT circuits. We then comment on how the technique can be extended straightforwardly to the synthesis of CNOT+Rz circuits and as a modification to a recently-proposed circuit simplification/extraction procedure for generic circuits based on the ZX-calculus.
A quantum algorithm for simulating non-sparse Hamiltonians
Authors: Wang Chunhao , Wossnig Leonard
Published: February 2021

We present a quantum algorithm for simulating the dynamics of Hamiltonians that are not necessarily sparse. Our algorithm is based on the input model where the entries of the Hamiltonian are stored in a data structure in a quantum random access memory (qRAM) which allows for the efficient preparation of states that encode the rows of the Hamiltonian. We use a linear combination of quantum walks to achieve poly-logarithmic dependence on precision. The time complexity of our algorithm, measured in terms of the circuit depth, is O(t\sqrt{N}\norm{H}\,\polylog(N, t\norm{H}, 1/\epsilon)), where t is the evolution time, $N$ is the dimension of the system, and $\epsilon$ is the error in the final state, which we call precision. Our algorithm can be directly applied as a subroutine for unitary implementation and quantum linear systems solvers, achieving \widetilde{O}(\sqrt{N}) dependence for both applications.
Image processing: why quantum?
Authors: Nagy Marius , Nagy Naya
Published: February 2021

Quantum Image Processing has exploded in recent years with dozens of papers trying to take advantage of quantum parallelism in order to offer a better alternative to how current computers are dealing with digital images. The vast majority of these papers define or make use of quantum representations based on very large superposition states spanning as many terms as there are pixels in the image they try to represent. While such a representation may apparently offer an advantage in terms of space (number of qubits used) and speed of processing (due to quantum parallelism), it also harbors a fundamental flaw: only one pixel can be recovered from the quantum representation of the entire image, and even that one is obtained non-deterministically through a measurement operation applied on the superposition state. We investigate in detail this measurement bottleneck problem by looking at the number of copies of the quantum representation that are necessary in order to recover various fractions of the original image. The results clearly show that any potential advantage a quantum representation might bring with respect to a classical one is paid for dearly with the huge amount of resources (space and time) required by a quantum approach to image processing.

An introduction and review on innovative silicon implementations of implantable/scalp EEG chips for data acquisition, seizure/behavior detection, and brain stimulation
Authors: Shi Weiwei , Zhang Jinyong , Zhang Zhiguo , Hu Lizhi , Su Yongqian
Published: February 2021

Technological advances in the semiconductor industry and the increasing demand and development of wearable medical systems have enabled the development of dedicated chips for complex electroencephalogram (EEG) signal processing with smart functions and artificial intelligence‐based detections/classifications. Around 10 million transistors are integrated into a 1 mm2 silicon wafer surface in the dedicated chip, making wearable EEG systems a powerful dedicated processor instead of a wireless raw data transceiver. The reduction of amplifiers and analog‐digital converters on the silicon surface makes it possible to place the analog front‐end circuits within a tiny packaged chip; therefore, enabling high‐count EEG acquisition channels. This article introduces and reviews the state‐of‐the‐art dedicated chip designs for EEG processing, particularly for wearable systems. Furthermore, the analog circuits and digital platforms are included, and the technical details of circuit topology and logic architecture are presented in detail.

Authors: Hu Wanrou , Huang Gan , Li Linling , Zhang Li , Zhang Zhiguo , Liang Zhen
Published: February 2021

Emotions, formed in the process of perceiving external environment, directly affect human daily life, such as social interaction, work efficiency, physical wellness, and mental health. In recent decades, emotion recognition has become a promising research direction with significant application values. Taking the advantages of electroencephalogram (EEG) signals (i.e., high time resolution) and video‐based external emotion evoking (i.e., rich media information), video‐triggered emotion recognition with EEG signals has been proven as a useful tool to conduct emotion‐related studies in a laboratory environment, which provides constructive technical supports for establishing real‐time emotion interaction systems. In this paper, we will focus on video‐triggered EEG‐based emotion recognition and present a systematical introduction of the current available video‐triggered EEG‐based emotion databases with the corresponding analysis methods. First, current video‐triggered EEG databases for emotion recognition (e.g., DEAP, MAHNOB‐HCI, SEED series databases) will be presented with full details. Then, the commonly used EEG feature extraction, feature selection, and modeling methods in video‐triggered EEG‐based emotion recognition will be systematically summarized and a brief review of current situation about video‐triggered EEG‐based emotion studies will be provided. Finally, the limitations and possible prospects of the existing video‐triggered EEG‐emotion databases will be fully discussed.
Assessing Parliament’s Response to the Covid-19 Pandemic
Authors: Hellyer Gabor
Published: February 2021

Parliament had to discharge its constitutional role in unprecedented conditions following the onset of the Covid-19 pandemic. How did it fare? This article assesses Parliament’s response to the pandemic across its core constitutional functions of legislating, scrutinising, financing, representing and providing a government. It argues that Parliament’s response was remarkably effective and resulted in meaningful permanent changes to the legislature’s operation. Nonetheless, the response also highlighted opportunities for further institutional strengthening regarding Parliament’s role in a national emergency.
Public Trust in Science and Research
Authors: Manning Suzanne , Walton Matthew
Published: February 2021

Innovation in science and research technology often raises questions of acceptability, ethics and governance processes. This article explores research assessment and ethics frameworks based on values, responsibility, relationships, trust and distributed power, which could give guidance to decision making around research and development investments in scientific institutes. Governance using a responsibility lens alongside risk mitigation, based on explicit ethical and moral values, allows critical evaluation of research programmes which seek to address inequities in society. Funding for formal research assessment structures that bring diverse perspectives together within institutions would facilitate ongoing dialogue with Mäori and local communities and strengthen decision making. The example of the current and future development of waste water-based epidemiology technologies is used to show how a responsible research approach could be applied.
Disability
Authors: Murray Sam , Loveless Roger
Published: February 2021

Disabled people and their whänau have poorer outcomes across a wide range of wellbeing and living standards measures.1 Yet disability analysis does not appear to be well integrated into government decision making on wellbeing. This article builds a framework for understanding disability in a wellbeing context by using the Treasury’s Living Standards Framework and Sophie Mitra’s human development model for disability and health. One of the most important aspects of Mitra’s model is the interaction between resources and structural factors. Structural factors, such as an inaccessible built environment, force disabled people to spend more resources to get the same outcomes as nondisabled people. Publicly funded disability support is essential to counteract these structural factors. We also need to improve the usability of the four capitals for disabled people and their whänau to reduce these structural barriers.
Does the Human Assisted Reproductive Technology Act 2004 need a review?
Authors: Legge Michael , Fitzgerald Ruth
Published: February 2021

The use of assisted reproductive technologies (ART) in New Zealand is governed by the Human Assisted Reproductive Technology Act 2004 (the HART Act), which provides for all procedures currently undertaken by fertility clinics and other centres involved with ART. Although the Act has provided good coverage for the use of ART over the last 16 years, it did not have a revision clause. Here, we explore whether the HART Act should be reviewed, and outline the important considerations that need to be taken into account to ensure that the legislation is up to date with current issues and technologies.
Updated inventory of glacier ice in New Zealand based on 2016 satellite imagery

Published: February 2021

Copyright © The Author(s), 2020. Published by Cambridge University Press. The only complete inventory of New Zealand glaciers was based on aerial photography starting in 1978. While there have been partial updates using 2002 and 2009 satellite data, most glaciers are still represented by the 1978 outlines in contemporary global glacier databases. The objective of this project is to establish an updated glacier inventory for New Zealand. We have used Landsat 8 OLI satellite imagery from February and March 2016 for delineating clean glaciers using a semi-Automatic band ratio method and debris-covered glaciers using a maximum likelihood classification. The outlines have been checked against Sentinel-2 MSI data, which have a higher resolution. Manual post processing was necessary due to misclassifications (e.g. lakes, clouds), mapping in shadowed areas, and combining the clean and debris-covered parts into single glaciers. New Zealand glaciers cover an area of 794 ± 34 km2 in 2016 with a debris-covered area of 10%. Of the 2918 glaciers, seven glaciers are >10 km2 while 71% is <0.1 km2. The debris cover on those largest glaciers is >40%. Only 15 glaciers are located on the North Island. For a selection of glaciers, we were able to calculate the area reduction between the 1978 and 2016 inventories.

The Last Glacial Maximum in the central North Island, New Zealand: Palaeoclimate inferences from glacier modelling
Authors: Eaves Shaun , Mackintosh AN , Anderson Brian , Doughty AM , Townsend DB , Conway CE , Winckler G , Schaefer JM , Leonard GS , Calvert AT
Published: February 2021

© Author(s) 2016. Quantitative palaeoclimate reconstructions provide data for evaluating the mechanisms of past, natural climate variability. Geometries of former mountain glaciers, constrained by moraine mapping, afford the opportunity to reconstruct palaeoclimate, due to the close relationship between ice extent and local climate. In this study, we present results from a series of experiments using a 2-D coupled energy balance-ice flow model that investigate the palaeoclimate significance of Last Glacial Maximum moraines within nine catchments in the central North Island, New Zealand. We find that the former ice limits can be simulated when present-day temperatures are reduced by between 4 and 7°C, if precipitation remains unchanged from present. The spread in the results between the nine catchments is likely to represent the combination of chronological and model uncertainties. The majority of catchments targeted require temperature decreases of 5.1 to 6.3°C to simulate the former glaciers, which represents our best estimate of the temperature anomaly in the central North Island, New Zealand, during the Last Glacial Maximum. A decrease in precipitation of up to 25% from present, as suggested by proxy evidence and climate models, increases the magnitude of the required temperature changes by up to 0.8°C. Glacier model experiments using reconstructed topographies that exclude the volume of post-glacial (< 15 ka) volcanism generally increased the magnitude of cooling required to simulate the former ice limits by up to 0.5°C. Our palaeotemperature estimates expand the spatial coverage of proxy-based quantitative palaeoclimate reconstructions in New Zealand. Our results are also consistent with independent, proximal temperature reconstructions from fossil groundwater and pollen assemblages, as well as similar glacier modelling reconstructions from the central Southern Alps, which suggest air temperatures were ca. 6°C lower than present across New Zealand during the Last Glacial Maximum.

Statistical methods of fracture characterization using acoustic borehole televiewer log interpretation
Authors: Massiot C , Townend John , Nicol A , McNamara DD
Published: February 2021

©2017. American Geophysical Union. All Rights Reserved. Acoustic borehole televiewer (BHTV) logs provide measurements of fracture attributes (orientations, thickness, and spacing) at depth. Orientation, censoring, and truncation sampling biases similar to those described for one-dimensional outcrop scanlines, and other logging or drilling artifacts specific to BHTV logs, can affect the interpretation of fracture attributes from BHTV logs. K-means, fuzzy K-means, and agglomerative clustering methods provide transparent means of separating fracture groups on the basis of their orientation. Fracture spacing is calculated for each of these fracture sets. Maximum likelihood estimation using truncated distributions permits the fitting of several probability distributions to the fracture attribute data sets within truncation limits, which can then be extrapolated over the entire range where they naturally occur. Akaike Information Criterion (AIC) and Schwartz Bayesian Criterion (SBC) statistical information criteria rank the distributions by how well they fit the data. We demonstrate these attribute analysis methods with a data set derived from three BHTV logs acquired from the high-temperature Rotokawa geothermal field, New Zealand. Varying BHTV log quality reduces the number of input data points, but careful selection of the quality levels where fractures are deemed fully sampled increases the reliability of the analysis. Spacing data analysis comprising up to 300 data points and spanning three orders of magnitude can be approximated similarly well (similar AIC rankings) with several distributions. Several clustering configurations and probability distributions can often characterize the data at similar levels of statistical criteria. Thus, several scenarios should be considered when using BHTV log data to constrain numerical fracture models.
The Alpine Fault hanging-wall viewed from within: Structural analysis of the ultrasonic image logs in the DFDP-2B borehole, New Zealand

Published: February 2021

©2018. American Geophysical Union. All Rights Reserved. Ultrasonic image logs acquired in the DFDP-2B borehole yield the first continuous, subsurface description of the transition from schist to mylonite in the hangingwall of the Alpine Fault, New Zealand, to a depth of 818 m below surface. Three feature sets are delineated. One set, comprising foliation and foliation-parallel veins and fractures, has a constant orientation. The average dip direction of 145° is subparallel to the dip direction of the Alpine Fault, and the average dip magnitude of 60° is similar to nearby outcrop observations of foliation in the Alpine mylonites that occur immediately above the Alpine Fault. We suggest that this foliation orientation is similar to the Alpine Fault plane at ∼1 km depth in the Whataroa valley. The other two auxiliary feature sets are interpreted as joints based on their morphology and orientation. Subvertical joints with NW-SE (137°) strike occurring dominantly above ∼500 m are interpreted as being formed during the exhumation and unloading of the Alpine Fault's hangingwall. Gently dipping joints, predominantly observed below ∼500 m, are interpreted as inherited hydrofractures exhumed from their depth of formation. These three fracture sets, combined with subsidiary brecciated fault zones, define the fluid pathways and anisotropic permeability directions. In addition, high topographic relief, which perturbs the stress tensor, likely enhances the slip potential and thus permeability of subvertical fractures below the ridges, and of gently dipping fractures below the valleys. Thus, DFDP-2B borehole observations support the inference of a large zone of enhanced permeability in the hangingwall of the Alpine Fault.

Sevilla y el río Guadalquivir en la planificación reciente: encuentros y desencuentros
Authors: Sainz Gutiérrrez Victoriano
Published: February 2021

La relación de Sevilla con el Guadalquivir presenta una doble vertiente: de una parte, el río ha sido para la ciudad una importante fuente riqueza gracias a la actividad comercial desarrollada en su puerto y, de otra, una causa de problemas por las frecuentes riadas que han venido dañando con regularidad su tejido edificado. La ingente obra hidráulica realizada desde finales del siglo XIX para mejorar la accesibilidad de las embarcaciones al puerto y defender la ciudad de las inundaciones no ha dejado de provocar conflictos tanto a nivel urbano como territorial. El artículo repasa la historia de esos conflictos dominados por una neta hegemonía portuaria, centrándose a continuación en los retos y oportunidades a los que se enfrenta la Sevilla metropolitana para dar un nuevo significado a los espacios vinculados al cauce vivo del río Guadalquivir y su llanura de inundación. La construcción de la ciudad-territorio contemporánea se presenta como una ocasión para integrarlos en la infraestructura verde metropolitana. En esa dirección han ido tanto el planeamiento urbano como el territorial vigente, pero el camino no está exento de dificultades, que aquí se ilustran con los debates recientes respecto al futuro de la dehesa de Tablada como gran parque periurbano.
Los equilibrios del agua oculta. Estrategias para un urbanismo ecosistémico en La Vall Baixa del Llobregat
Authors: Crosas Armengol Carles , Martí Elias Joan
Published: February 2021

En el Área metropolitana de Barcelona, el territorio de La Vall Baixa conforma una ciudad lineal discontinua modelada por las lógicas de la geografía y el agua. La perspectiva histórica de su desarrollo territorial y urbano ofrece algunas lecciones interesantes sobre el buen entendimiento entre la forma urbana, la agricultura y el agua. Sin embargo, la implantación de las modernas infraestructuras de movilidad a partir de 1970 y algunas extensiones urbanas invasivas derivadas han comportado cambios sustanciales en los equilibrios “líquidos” de este territorio. El análisis de la situación actual sugiere algunas estrategias para seguir con la mejora del ciclo del agua en este fragmento metropolitano, que ha experimentado recientemente una exitosa recuperación del lecho del río. A través de estrategias combinadas de artificialización de los sistemas de agua y la naturalización del paisaje, se apunta a la importancia del agua “oculta” que nutre el acuífero como un elemento fundamental que debiera guiar algunos proyectos urbanísticos para la mejora del metabolismo territorial.

MUERTES EVITABLES ASOCIADAS A LA IMPLEMENTACIÓN DE INFRAESTRUCTURA VERDE URBANA EN QUITO
Authors: Rodríguez Sebastián , Mena Alexandra , Garzón Daniel , Ramírez Cevallos Francisco , Chuquer-Sola David
Published: February 2021

En las últimas décadas, el desarrollo económico de Quito ha venido acompañado con un deterioro en su calidad del aire, principalmente por el aumento progresivo de su flota vehicular. Ante ello, la autoridad ambiental de la zona registra concentraciones que superan las normas nacionales e internacionales de calidad del aire en los parámetros de PM10, PM2.5 y O3. Ante este escenario, la implementación de infraestructura verde urbana (IVU) emerge como una alternativa para el mejoramiento de la calidad del aire en microambientes, sin embargo, sus costos limitan su aplicación. El trabajo presentado estima, mediante la metodología AP-HRA, los efectos económicos y en salud pública que se obtendría producto de una implementación agresiva de IVU en ocho parroquias de Quito. Los resultados generados son alentadores dado que una reducción del 30 % en PM10 y O3 y 1 % en PM2.5 podría evitar 190 muertes anualmente en la zona de estudio, con un beneficio económico para la sociedad de 139,7 millones de USD. Las estimaciones presentadas pueden servir de herramienta para los tomadores de decisión con el fin de instrumentar políticas públicas que promuevan la implementación de IVU en espacios públicos y privados.

El objetivo de este artículo es el de abordar críticamente el giro afectivo vinculado a la teoría cultural actual, problematizando su historicidad para describir la raíz gubernamental de la dimensión de las pasiones por medio de una tensión de las nociones de emoción y afecto, las cuales emergen como campo de estudio contingente a la axiomática capitalista contemporánea. Nuestra hipótesis es que la potencia gubernamental del capitalismo reside en la eficiencia con que los cuerpos son inscritos por medio de su emocionalización en una escena o “miedo/ambiente” acondicionado para su agrupamiento en función de la atenuación de su fuerza afectiva, existiendo una operación de traducción de afectos en emociones que sitúa, como centro de gravedad para la politización del presente.
La planificación urbana y su incidencia en los procesos de gentrificación
Authors: González Redondo Carolina
Published: February 2021

Este trabajo indaga sobre las sucesivas intervenciones públicas y privadas que crearon las condiciones para el desarrollo de un incipiente proceso de gentrificación en un tramo de la inconclusa ex Autopista 3, ubicado en el barrio de Villa Urquiza de la ciudad de Buenos Aires. Profundiza en la propuesta urbana más reciente para esta zona, el Barrio Parque Donado Holmberg, dando cuenta de las transformaciones que esta normativa promueve en el territorio.Así, se presta atención al modo en el que se vinculan un tipo de orientación de gobierno (el empresarialismo urbano) con un tipo de intervención sobre el territorio (el urbanismo neoliberal) y -mediado por el procesamiento de las distintas políticas- se producen las condiciones para un fenómeno creciente en las ciudades contemporáneas: la gentrificación.

Published: February 2021

Uno de los principales retos sociales actuales es la gestión de la diversidad cultural y la integración basada en la igualdad de las poblaciones migrantes o minoritarias en los países de acogida o entre los miembros del grupo mayoritario. La perspectiva multicultural puede tener un importante rol en el afrontamiento de estos retos. Esta perspectiva tiene efectos positivos sobre las relaciones intergrupales, el nivel de creatividad, el compromiso intelectual y cívico y sobre el aprendizaje y el nivel de compromiso organizacional. Este artículo aborda desde una perspectiva psicosocial los precedentes históricos y su definición, los efectos de su aplicación en diferentes contextos y los retos que todavía, en la práctica, el multiculturalismo tiene que afrontar.

Purpose: This paper aims to explore an integrated relationship between performance appraisal, succession planning, and career development in the Indian context. A very few empirical studies could be seen in identifying a relationship between the proposed variables.

Design/methodology/approach: An empirical study was conducted by employing the cross-sectional survey-based research design along with the convenience sampling method. Around, 167 questionnaires were circulated through online via Google forms. Finally, 134 responses were received from respondents having 80.23% response rate. The responses were subject to analysis using normality check, confirmatory factor analysis, correlation, model fit and multiple hierarchical regression analysis.

Findings: Results reveal that all three study variables are positively associated with each other. This study fully supports the applicability of performance appraisal, and succession planning as crucial predictors of career development more specifically in the Indian context.

Research limitations/implications: This current study is conducted using online data collection procedure, while future studies may use in-depth interview and daily diary studies.

Practical implications: This study exhibits how employee career development can be initiated through succession planning and performance appraisal. This study also suggested that the organizations which emphasize on an effective policy guideline for systematic performance appraisal will probably support the succession planning and career development.

Originality/value: Notably, no prior studies empirically investigate the proposed relationship in Indian context. Furthermore, the findings serve as a policy guideline for the performance appraisal, succession planning and career development literature in an Indian organizational setting.

Spatial (three-dimensional - 3D) computer model of the T-x-y diagram of the Ag - Cu - Ni system, which is promising for the development of environmentally friendly solders, is presented. The model is constructed on the basis of published data on the binary systems forming this ternary system, the concentration projection of the liquidus surfaces, and four isothermal sections. It is shown that the phase diagram (PD) consists of 14 surfaces and 9 phase regions. The adequacy of the model is confirmed by comparing the isothermal sections and the liquidus projection.

Published: February 2021

Cationic dyes of various natures have been investigated in order to select a dye that is stable under strongly alkaline conditions and applicable for the quantitative extraction-photometric determination of higher carboxylic acids. The nature of the dye, solvent, the length of the hydrocarbon radical of carboxylic acids and the pH of the aqueous phase for the extraction of ionic associates of higher carboxylic acids with cationic dye with pyronin G were experimentally studied. The study substantiates the practical application of the cationic dye pyronin G as an effective reagent for the quantitative extraction-photometric determination of higher carboxylic acids.

Methods for preparation of nanocomposites of modified detonation nanodiamonds (DND) with metallic palladium have been developed and their catalytic activity in the Suzuki-Miyaura cross-coupling reaction in various reaction media has been studied. Methods for the regeneration of palladium-containing nanocomposites from the reaction mixture have been developed. The high catalytic activity of nanocomposites is confirmed by kinetic analysis based on the results of chromatographic analysis of the reaction mixture and is comparable to the literature data about similar catalytic systems. Regenerated nanocomposites showed the retention of catalytic activity for 3 consecutive cross-coupling cycles on model systems.
Effect of ultraviolet on thiamine and thiamine disulfides

Published: February 2021

In a neutral medium, the exposure of thiamine disulfide to the ultraviolet of solar radiation (as well as to the ultraviolet radiation of mercury lamp with λ > 300 nm) results in the formation of a thiamine molecule with closed thiazole ring and a molecule of thiamine thiazolone. Asymmetric thiamine disulfides, e.g., thiamine propyl disulfide, on exposure to ultraviolet (UVA range) produced thiamine and propyl disulfides. Thiamine and thiazolone of thiamine are stable upon exposure to light of 320-400 nm (UVA range). UV irradiation within spectral range of 200-300 nm results in further photodestruction of thiamine and thiamine thiazolone and production of 2-methyl-4-amino-5aminomethyl-pyrimidine as the main photoproduct. The possibility to use thiamine disulfide derivatives as a promising class of anti-cataract drugs as well as drugs to decrease the toxic effect of ultraviolet radiation on human retina is discussed.

Published: February 2021

The influence of polycarboxylate and naphthalene-sulfone superplasticizers, paraffin hydrophobizator and complex hydrophobic-plasticizing additives on the structural characteristics, physical-mechanical, hydrophysical properties, corrosion resistance and frost resistance of fine-grained Portland cement concretes was studied. Structural parameters of concretes (average and true density; density coefficient; total, open, closed porosity) were compared with compressive strength, water absorption, softening coefficients and salt resistance of materials. It is shown that the introduction of superplasticizers increases the density, softening coefficients and salt resistance, reduces the water absorption of Portland cement structures, and the use of paraffin hydrophobization and complex hydrophobic-plasticizing additives increases the closed porosity as a result of the formation of mosaic hydrophobic films on the surface of solid phases, which have a positive effect on the hydrophysical and physical-mechanical properties of concretes.

The paper presents the results of stationary multifactor field experiment on study of the mutual impact of various systems of soil deep and surface tillage in combination with various levels of organic and mineral fertilizers application on crop rotation performance, as well as on a number of agrochemical indicators of black soil fertility. Researches were carried out as a stationary field experiment on the experimental field of Bila Tserkva National Agrarian University in 2013-2018. During the crop rotation in all the studied tillage methods, especially mouldboardless and disking tillage, the hydrolytic acidity of the arable layer increased with increase in fertilizer rates, and the amount of bases absorbed, saturation degree, level of exchangeable calcium and magnesium cations decreased, but in most cases these changes were not significant. Systematic mouldboardless and disking tillage enhance the topsoil heterogeneity in relation to agrochemical indicators of its fertility. Heterogeneity increases with increase in the level of applied fertilizers. With the mouldboard tillage during the crop rotation period at unfertilized areas, the largest part of humus loss in the arable layer is observed in the top, and the smallest - in its bottom parts; the opposite pattern was observed on fertilized areas at the highest rate. With mouldboardless and disking tillage, directly opposite patterns were observed in comparison with mouldboard tillage. An annual application of 8 t/ha of manure + N76P64K57 stabilizes the humus state of the arable soil layer when carrying out differentiated and disking tillage in crop rotation. Fertilization rate of 12 t/ha of manure + N95P82K75 for these tillage options a significant increase in humus and total nitrogen reserves is provided.
