Utilization of Basic Oxygen Furnace Slag in Geopolymeric Coating for Passive Radiative Cooling Application
Authors: Wu Chia-Ho , Huang Chih-Hong , Li Yeou-Fong , Lee Wei-Hao , Cheng Ta-Wui
Published: May 2020

Basic oxygen furnace slag (BOFs) is difficult to reutilize because it contains excessive free lime, and thus causes serious expansion. For this reason, how to reuse BOF slag has turned out to be an imperative issue in order to meet the concept of a circular economy. The key intention of this research work is to develop a new way to reutilize BOF slag, which due to its high emissivity in the 8–13 µm wavelength range, can be used as a sustainable, passive radiative cooling material. Passive radiative cooling, without the consumption of any energy, achieves the cooling of a surface by reflecting the sunlight and radiating the heat throughout the outer space (not absorbed by the atmosphere). BOF slag is used as a radiative cooling material in geopolymeric coating. This coating possesses an emissivity of 0.95 within the range of 8–13 µm and also has high conductivity, but its gray appearance absorbs too much heat. Therefore, by improving the situation through a double-layer structure, a temperature drop of 5.9 °C was reached compared to non-coated concrete under simulated sunlight, simultaneously with a low heating rate and high cooling rate. Besides, the binding strength between the geopolymeric coating and Portland cement concrete is comparable to two commercial organic paints. It is highly probable that the utilization of BOF slag in geopolymeric coating is energy saving and also feasible for passive radiative cooling applications. Hence, it can greatly decrease indoor temperature and improve the comfort of people living in buildings.

Published: May 2020

Information technology advancements integrated with the e-commerce supply chain allow participants in the business process to effectively work with large volumes of data and control transactions. To improve the profitability and competitiveness of e-commerce companies, a blockchain solution was incorporated into the global B2B (Business-to-Business) supply chain. This technology simplified the transaction process by providing all participants in the sustainable B2B buying process with the same data about the trade. Overall, the use of blockchain improved the efficiency of logistics and digital documentation which reached 74% and 75%, respectively. The main advantage of using blockchain is that it creates a decentralized database that is secure. In addition, it increases the speed of payment and the reliability and transparency of data transfer. Further research may focus on the use of blockchain in green logistics to improve environmental sustainability in the e-commerce supply chain.
First-Principles Calculations of High-Pressure Physical Properties of Ti0.5Ta0.5 Alloy
Authors: Yu Fang , Liu Yu
Published: May 2020

In this paper, an in-depth theoretical study on some physical properties of Ti0.5Ta0.5 alloy with systematic symmetry under high pressure is conducted via first-principles calculations, and relevant physical parameters are calculated. The results demonstrate that the calculated parameters, including lattice parameter, elastic constants, and elastic moduli, fit well with available theoretical and experimental data when the Ti0.5Ta0.5 alloy is under T = 0 and P = 0 , indicating that the theoretical analysis method can effectively predict the physical properties of the Ti0.5Ta0.5 alloy. The microstructure and macroscopic physical properties of the alloy cannot be destroyed as the applied pressure ranges from 0 to 50GPa, but the phase transition of crystal structure may occur in the Ti0.5Ta0.5 alloy if the applied pressure continues to increase according to the TDOS curves and charge density diagram. The value of Young’s and shear modulus is maximized at P = 25   GPa . The anisotropy factors A ( 100 ) [ 001 ] and A ( 110 ) [ 001 ] are equal to 1, suggesting the Ti0.5Ta0.5 alloy is an isotropic material at 28 GPa, and the metallic bond is strengthened under high pressure. The present results provide helpful insights into the physical properties of Ti0.5Ta0.5 alloy.

Published: May 2020

Induced chirality (achiral target in chiral matrix such as proteins) sometimes play a useful role in evaluating supramolecular systems involving biomolecules. Enzymatic fuel cells, which generate electricity via enzymatic redox reactions at electrodes hold a significant potential for sustainable power. Bacterial laccase, a multi-copper oxidase, was used in the cathodic compartment of the enzymatic biofuel cells because of its low redox potential. Three new salen Cu(II) complexes were designed and investigated as mediators. The Schiff base ligands consisted of both a redox-active (anthraquinone) and a photochromic (azobenzene) moiety. The interaction between laccase and a mediator was examined with induced circular dichroism (CD) and the docking tool to observe in which of the laccase domains the mediators bind as well as study the photo-induced tuning of both the cis-trans photoisomerization and orientation by the Weigert effect. Both the electrochemical and photochromic properties are also discussed and compared using density functional theory (DFT), time-dependent (TD)-DFT, and docking simulations.
Self-Concept in China: Validation of the Chinese Version of the Five-Factor Self-Concept (AF5) Questionnaire
Authors: Chen Fangzhou , Garcia Oscar F. , Fuentes Maria C. , Garcia-Ros Rafael , Garcia Fernando
Published: May 2020

The principle of invariance is a mandatory methodological requirement for the psychological measures, even when items such as self-concept measures frequently present asymmetric heavy-tailed distributions. Few validated self-concept instruments can be applied in Eastern–Western cross-cultural studies. The Five-Factor Self-Concept Questionnaire (AF5) is one of the few psychometrically sound instruments used to assess multidimensional self-concept in Spanish-speaking samples. The availability of the AF5 in Spanish and Chinese would facilitate cross-cultural research. To validate the Chinese version of the AF5, we used multisample confirmatory factor analysis with transformed dichotomous scales from the median to compare four alternative theoretical models. The sample consisted of 2507 participants (52.3% women) from China (n = 1298) and Spain (n = 1209), ranging in age from 19 to 35. Analyses confirmed the five-factor structure of the Chinese AF5 (i.e., academic, social, emotional, family, and physical) compared to the Spanish sample. Moreover, the Chinese version of the AF5 was found to be invariant in terms of item-factor weights, factor variance, and between-factor covariance, compared to the original Spanish version. The findings from this first validation study indicate that the Chinese version of the AF5 is an acceptable measure for use with Chinese-speaking adolescents and young adults.
Criticality or Supersymmetry Breaking?

Published: May 2020

In many stochastic dynamical systems, ordinary chaotic behavior is preceded by a full-dimensional phase that exhibits 1/f-type power spectra and/or scale-free statistics of (anti)instantons such as neuroavalanches, earthquakes, etc. In contrast with the phenomenological concept of self-organized criticality, the recently found approximation-free supersymmetric theory of stochastics (STS) identifies this phase as the noise-induced chaos (N-phase), i.e., the phase where the topological supersymmetry pertaining to all stochastic dynamical systems is broken spontaneously by the condensation of the noise-induced (anti)instantons. Here, we support this picture in the context of neurodynamics. We study a 1D chain of neuron-like elements and find that the dynamics in the N-phase is indeed featured by positive stochastic Lyapunov exponents and dominated by (anti)instantonic processes of (creation) annihilation of kinks and antikinks, which can be viewed as predecessors of boundaries of neuroavalanches. We also construct the phase diagram of emulated stochastic neurodynamics on Spikey neuromorphic hardware and demonstrate that the width of the N-phase vanishes in the deterministic limit in accordance with STS. As a first result of the application of STS to neurodynamics comes the conclusion that a conscious brain can reside only in the N-phase.

Published: May 2020

Hepatitis A virus (HAV) infection is one of the major causes of acute hepatitis, and this infection occasionally causes acute liver failure. HAV infection is associated with HAV-contaminated food and water as well as sexual transmission among men who have sex with men. Although an HAV vaccine has been developed, outbreaks of hepatitis A and life-threatening severe HAV infections are still observed worldwide. Therefore, an improved HAV vaccine and anti-HAV drugs for severe hepatitis A should be developed. Here, we reviewed cell culture systems for HAV infection, and other issues. This review may help with improving the HAV vaccine and developing anti-HAV drugs.
From Building Dams to Fetching Water: Scales of Politicization in the Indus Basin
Authors: Aijaz Abdul , Akhter Majed
Published: May 2020

Water flows through and informs the socio-spatial geography of the Indus waterscape in Pakistan in myriad ways. This paper argues that state-led water development has historically attempted to bypass political conflict by invoking techno-scientific authority to render water development as a purely techno-managerial pursuit. By invoking the scientifically objective, depoliticized knowledge of water resources, the state shifts the politics of water to the domain of politics of knowledge to disarm communities with cultural and political claims to water. These attempts to “depoliticize” are always accompanied by attempts to repoliticize water—both from within the state apparatus and from society more generally. The paper stages an engagement between the historical geography of the Indus and the field of critical water geography to develop an understanding of politicization as inter-scalar and relatively insensitive to changes in the ruling political regime. We present a novel periodization of the hydrosocial relations in the Indus Basin that highlight periods of relative continuity and coherence in terms of the political regime in the water sector. Despite the significance of these shifts for political history, we argue that the historical geography of water reveals a techno-managerial knowledge/value structure with a deep and structural continuity. Using a scale-sensitive understanding of politicization to analyze the historical and contemporary geography of the Indus allows us to go behind shifts in political regime to identify the deeper structures at play. These are the epistemological and ideological structures that produce a dynamic of attempted depoliticization and repoliticization in the Indus Basin.
Intermittent Water Supply Management, Household Adaptation, and Drinking Water Quality: A Comparative Study in Two Chinese Provinces
Authors: Li Hongxing , Cohen Alasdair , Li Zheng , Lv Shibo , He Zuan , Wang Li , Zhang Xinyi
Published: May 2020

Intermittent water supply (IWS) is a relatively common phenomenon across the world as well as in rural and peri-urban areas across China, though there has been little IWS-focused research from China published to date. IWS consumers typically adopt a range of strategies to cope with insufficient water supply, poor drinking water quality, and associated inconveniences. In this study, we collected a range of data from small-scale utilities and households in two IWS systems and two continuous water supply (CWS) systems, as well as from comparison groups, in Shandong and Hubei provinces. Data collection included water quality testing, interviews, and surveys on behavioral adaptations, coping strategies, water-related health perceptions, and other metrics of consumer satisfaction. Overall, we found that the IWS coping strategies employed in northern China (Shandong) were associated with generally safe, but inconvenient, water access, whereas adaptation strategies observed in southern China (Hubei) appeared to improve convenience, but not water quality. Compared to the CWS comparison groups, we did not observe significant differences in water- and sanitation-related behaviors in the IWS groups, suggesting interventions to increase adaptive and protective behaviors at the household level might further improve safe water access for households living with IWS. Overall, although the water supply infrastructure in these study areas appeared to be in relatively good condition, in contrast to reported data on IWS systems in other countries, we observed multiple risk factors associated with the water treatment and distribution processes in these IWS systems. Among policy recommendations, our results suggest that the implementation of Water Safety Plans in China would likely improve the management of drinking water treatment and, by extension, safe drinking water supply under conditions of IWS.
Role of Cluster Validity Indices in Delineation of Precipitation Regions
Authors: Bhatia Nikhil , Sojan Jency M. , Simonovic Slobodon , Srivastav Roshan
Published: May 2020

The delineation of precipitation regions is to identify homogeneous zones in which the characteristics of the process are statistically similar. The regionalization process has three main components: (i) delineation of regions using clustering algorithms, (ii) determining the optimal number of regions using cluster validity indices (CVIs), and (iii) validation of regions for homogeneity using L-moments ratio test. The identification of the optimal number of clusters will significantly affect the homogeneity of the regions. The objective of this study is to investigate the performance of the various CVIs in identifying the optimal number of clusters, which maximizes the homogeneity of the precipitation regions. The k-means clustering algorithm is adopted to delineate the regions using location-based attributes for two large areas from Canada, namely, the Prairies and the Great Lakes-St Lawrence lowlands (GL-SL) region. The seasonal precipitation data for 55 years (1951–2005) is derived using high-resolution ANUSPLIN gridded point data for Canada. The results indicate that the optimal number of clusters and the regional homogeneity depends on the CVI adopted. Among 42 cluster indices considered, 15 of them outperform in identifying the homogeneous precipitation regions. The Dunn, D e t _ r a t i o and Trace( W − 1 B ) indices found to be the best for all seasons in both the regions.
Metal-Organic Framework Membranes and Membrane Reactors: Versatile Separations and Intensified Processes
Authors: Ban Yujie , Cao Na , Yang Weishen
Published: May 2020

Metal-organic frameworks are an emerging and fascinating category of porous solids that can be self-assembled with metal-based cations linked by organic molecules. The unique features of MOFs in porosity (or surface areas), together with their diversity for chemical components and architectures, make MOFs attractive candidates in many applications. MOF membranes represent a long-term endeavor to convert MOF crystals in the lab to potentially industry-available commodities, which, as a promising alternative to distillation, provide a bright future for energy-efficient separation technologies closely related with chemicals, the environment, and energy. The membrane reactor shows a typical intensified process strategy by combining the catalytic reaction with the membrane separation in one unit. This review highlights the recent process of MOF-based membranes and the importance of MOF-based membrane reactors in relative intensified chemical processes.
ADULT EDUCATION IN UKRAINE: PRECONDITIONS OF FORMATION, PROSPECTS OF DEVELOPMENT
Authors: Lukianova Larysa
Published: May 2020

Socio-economic changes in the late 20th century and at the beginning of the 21st century, technological and socio-cultural transformations at global and local levels had a significant impact on de-termining the role of adult education for modern Ukrainian society and outline its further development vec-tor. The need for mass professional retraining of adults to ensure socio-economic reforms, as well as the for-mation of Ukraine’s civil society, is prompted by the development of an adult continuous education flexible system to respond to the whole society’s challenges and the demands of its specific layers. The author states that Ukraine has a rich historical experience of adult education (from weekend schools, re-education schools, part-time universities, universities for workers and peasants to the creation of research institutions in the system of the National Academy of Educational Sciences, engaged in research and theoretical analysis of an-dragogy and departments of andragogy at higher education institutions). Contemporary landscape of adult education in the country has been analyzed. According to the author, the situation is ambiguous and charac-terized by both positive (awareness of the role of adult education) and negative (reduction of terms of study, commercialization of many adult education pathways, funding cutbacks) features. However, positive changes prevail: branching of goals and education fields; diversification of educational services, development of adult education flexible structures that can meet modern requirements. The system of adult education in Ukraine has been analyzed. According to structural features, it has formal and informal components. The emphasis is placed on the role of non-formal education. The author concludes that adult education in Ukraine is gaining more importance in modern society.

The purpose of this study is to show that the categories of gods, humans, and animals in the Western Zhou were not fixed, but always implied the possibility of fluidity and transformation. First of all, this paper depicts human beings who have become prisoners of war and are mobilized for human sacrifice. Human beings entered the process of animalization beyond the boundaries between themselves and animals. But man was also beyond human and divine boundaries. Human beings are transformed into ancestors after death, inhabiting heaven and connecting with the human world. Animals were the objects to be managed and controlled by humans. Hunting was the most effective way for humans to control animals. Animals, on the other hand, were the first to be called when there was a need to describe the world of the gods. The hybrid form most often found in bronze animal ornaments was mobilized to describe this divine world. This strongly suggests that animals are beings that cannot be completely controlled by humans. Finally, animals were sacrificed in sacrifice, and the sacralization of animals aimed to transform the animals into beings suitable for sacrifice. By doing so, the animal loses its identity as an animal and narrows its distance from the divine world.

GIUSEPPE ZAMBONI INTERPRETE DI KANT
Authors: MARCOLUNGO Ferdinando Luigi
Published: May 2020

All’interno della Neoscolastica italiana nella prima metà del Novecento, Giuseppe Zamboni (1875-1950) occupa un posto particolare per la sua gnoseologia pura, non molto lontana per alcuni aspetti dall’impianto della fenomenologia husserliana, soprattutto per la sua critica al positivismo e l’attenzione allo sviluppo delle nostre conoscenze a partire dai dati immediati offerti alla coscienza. Zamboni fu tra il gruppo dei primi docenti che diedero vita all’Università Cattolica del Sacro Cuore di Milano: nel decennio del suo insegnamento (1921-1932) si occupò a più riprese della Critica della ragion pura di Kant, sia con diversi saggi sulla Rivista di filosofia neoscolastica, sia con un volume di Studi esegetici, critici, comparativi apparso l’anno stesso del suo allontanamento definitivo dalla Cattolica. Dall’esame di tale testo si possono comprendere non solo le ragioni del dissenso, ma anche l’interesse che la sua interpretazione può rivestire oggi. Zamboni rivendica la capacità dell’elaborazione intellettiva dei dati della sensibilità ad opera dell’astrazione disindividuante, il ruolo fondamentale del corpo proprio nella rappresentazione dello spazio e soprattutto la centralità dell’io dei sentimenti e degli atti di volontà, accanto all’io conoscitivo puro dell’appercezione trascendentale kantiana.
WHAT LEIBNIZ MISSED – OR KANT MISREAD? KANT’S CRITIQUE OF LEIBNIZIAN METAPHYSICS IN LIGHT OF TWO RECENT INTERPRETATIONS
Authors: HAHMANN Andree
Published: May 2020

Kant famously criticizes Leibniz for his apparent neglect to observe the difference between two sources of cognition: understanding and intuition. This is the reason that Leibniz supposedly intellectualized the phenomena by identifying them with things in themselves. In Kantian terms, Leibniz fell prey to an amphiboly of concepts which, in the case of his understanding of substance, has led him to assume monads—that is to say, ideal unities which exist in a state of pre-established harmony; for this is the only possible form of community between ideal substances. Distinct versions of this argument can be found in Kant’s Critique of Pure Reason, notably in the notoriously difficult passage entitled “On the amphiboly of concepts of reflections”, and in some later writings, such as the Kantian reply to the self-declared Leibnizian Johann August Eberhard (On a Discovery whereby any New Critique of Pure Reason is to be made Superfluous by an Older One, from 1790) or the late fragment What Real Progress has Metaphysics made in Germany since the Time of Leibniz and Wolff? (originally from 1793, but published post mortem in 1804).
El concepto de pónos en Antístenes
Authors: Brancacci Aldo
Published: May 2020

El concepto de pónos (“esfuerzo”) es el fundamento de la ética de Antístenes, en la que se conecta estrechamente con el de phrónesis (“inteligencia”, “sabiduría”): ambos conceptos definen la acción moral. En particular, en el pónos se expresan el ejercicio constante, la capacidad de persistir en una tarea y, en un nivel aun superior, la energía espiritual, que se requieren para la realización de la virtud en las obras y que conducen a la conquista de la felicidad. Ello es coherente con el hecho de que la sophía antisténica se manifiesta en un complejo de funciones que, conforme al significado teórico propio del intelectualismo ético socrático, presuponen, por un lado, la unidad de teoría y praxis y, por otro, la convergencia de conocimiento y voluntad.
POR UMA ABORDAGEM HIERÁRQUICA DA GRAMATICALIZAÇÃO: UM EXERCÍCIO DE ANÁLISE
Authors: Fontes Michel Gustavo
Published: May 2020

O objetivo deste artigo é caracterizar o que tem sido chamado de ‘abordagem hierárquica da gramaticalização’ (cf. HENGEVELD, 2017; FONTES, 2016; 2018).

A intenção é, portanto, mostrar de que modo é possível compatibilizar os pressupostos teórico-metodológicos que arquitetam o modelo da Gramática Discursivo-Funcional, de Hengeveld e Mackenzie (2008), com os princípios que definem e identificam o processo de gramaticalização, em sua concepção mais clássica (HOPPER; TRAUGOTT, 2003; BRINTON; TRAUGOTT, 2005). Para tanto, toma-se, como objeto de estudo e de descrição linguística, a multifuncionalidade do item ‘ainda’ no português contemporâneo, caracterizada, por Fontes (2016), a partir de quatro diferentes usos:‘ainda’ fasal, ‘ainda’ polar, ‘ainda’ enfático e ‘ainda’ expansivo. O artigo demonstra que esses quatro usos de ‘ainda’ evidenciam uma trajetória de gramaticalização que, com base na Gramática Discursivo-Funcional, pode ser descrita a partir de dois tipos de mudança, conforme propõe Hengeveld (2017): uma mudança de conteúdo, caracterizada pela expansão (ou pelo aumento) nas relações de escopo contraídas por ‘ainda’, e uma mudança formal, marcada pela decategorização de ‘ainda’.

Assessment of cartographic outputs: analysis of mental maps of orienteering runners
Authors: Kynčlová Martina , Hudeček Tomáš , Bláha Jan D.
Published: May 2020

The article deals with analysis of mental maps which were obtained by questioning athletes – orienteering runners. Using the prerequisite of measurability of their sports performance, it is possible to measure the accuracy of assessment methods of mental maps. Thirty mental maps were acquired via a two-section questionnaire; they were assessed with the help of two methods – frequency measurement and determined weights and criteria. The results of the first method were visualised using software into aggregated maps which enable an overall view. The second method provides individual point of view on each athlete and their performance abilities. Comparison of both methods proves the initial hypothesis.
Some criteria of boundedness of the L-index in direction for slice holomorphic functions of several complex variables
Authors: Bandura Andriy , Skaskiv Oleh
Published: May 2020

We investigate the slice holomorphic functions of several complex variables that have a bounded \(L\)-index in some direction and are entire on every slice \(\{z^0+t\mathbf{b}: t\in\mathbb{C}\}\) for every \(z^0\in\mathbb{C}^n\) and for a given direction \(\mathbf{b}\in\mathbb{C}^n\setminus\{\mathbf{0}\}\). For this class of functions, we prove some criteria of boundedness of the \(L\)-index in direction describing a local behavior of the maximum and minimum moduli of a slice holomorphic function and give estimates of the logarithmic derivative and the distribution of zeros. Moreover, we obtain analogs of the known Hayman theorem and logarithmic criteria. They are applicable to the analytic theory of differential equations. We also study the value distribution and prove the existence theorem for those functions. It is shown that the bounded multiplicity of zeros for a slice holomorphic function \(F:\mathbb{C}^n\to\mathbb{C}\) is the necessary and sufficient condition for the existence of a positive continuous function \(L: \mathbb{C}^n\to\mathbb{R}_+\) such that \(F\) has a bounded \(L\)-index in direction.

Published: May 2020

Further positive social and economic development (SED) requires modelling and analysis for evaluating its results to ground directions for future development. The purpose of the paper is to study the problem of estimating of SED, to form the methodology for modelling its results and to create an aggregated econometric indicator within the framework of unified conceptual approach for the European Union (EU) countries. To achieve this goal, it is necessary to solve the following objectives: to determine the essence of the concept of SED, to study traditional approaches to measure SED, to give an overview of the DP2 modelling method, to discover and structure the elements of SED in the EU countries and to argue a conceptual approach to modelling its outcomes. The study is based on the method of mathematical modelling in economics based on Distance P2 method. Econometric modelling, as well as regression analyze, was used to develop a synthetic indicator DP2 for evaluating SED of the EU countries. Also, the research process was based on analysis, synthesis and the system approach for information processing, as well as on the method of comparative and statistical analysis, quality and quantity analysis. The results of the deep research showed that there is no unified approach to modelling SED. The Distance P2 method was first proposed to measure SED at the national level exactly for the EU. The methodology for measuring SED specifically for the EU countries based on the conceptual approach was developed and substantiated. Based on the proposed methodology and taking into account the special characteristics of the region studied - the social and economic DP2 indicator for the EU countries was created. This study proposes to build a synthetic indicator DP2 to model results of progress in SED, especially in the EU. The practical implications of the synthetic indicator DP2 for modelling and analysis of SED of the EU countries can be a prospect for further research. Applied aspect of these studies is advising the EU's public policy with the aim of advancing. Using the DP2 synthetic indicator of SED for the EU countries will identify and substantiate the main directions for developing the country's domestic policy to improve the quality of life of the populations. Also, the results of the study can be used for advisory purposes to develop and optimize the EU development strategy 2020-2030. The value and originality of the paper lie in further application of the methodology of modelling the SED of the EU countries through synthetic indicator DP2. This will expand opportunities for increasing the national economy’s efficiency, that is highly important in terms of increased international competition.

Phonon dynamics is explored in mechanically exfoliated two-dimensional WSe2 using temperature-dependent and laser-power-dependent Raman and photoluminescence (PL) spectroscopy. From this analysis, phonon lifetime in the Raman active modes and phonon concentration, as correlated to the energy parameter E0, were calculated as a function of the laser power, P, and substrate temperature, T. For monolayer WSe2, from the power dependence it was determined that the phonon lifetime for the in-plane vibrational mode was twice that of the out-of-plane vibrational mode for P in the range from 0.308 mW up to 3.35 mW. On the other hand, the corresponding relationship for the temperature analysis showed that the phonon lifetime for the in-plane vibrational mode lies within 1.42× to 1.90× that of the out-of-plane vibrational mode over T = 79 K up to 523 K. To provide energy from external stimuli, as T and P were increased, peak broadening in the PL spectra of the A-exciton was observed. From this, a phonon concentration was tabulated using the Urbach formulism, which increased with increasing T and P; consequently, the phonon lifetime was found to decrease. Although phonon lifetime decreased with increasing temperature for all thicknesses, the decay rate in the phonon lifetime in the monolayer (1L) material was found to be 2× lower compared to the bulk. We invoke a harmonic oscillator model to explain the damping mechanism in WSe2. From this it was determined that the damping coefficient increases with the number of layers. The work reported here sheds fundamental insights into the evolution of phonon dynamics in WSe2 and should help pave the way for designing high-performance electronic, optoelectronic and thermoelectric devices in the future.

Novel multistage redox tetrathiafulvalenes (TTFs) bearing 6-aryl-1,4-dithiafulvene moieties were synthesized by palladium-catalyzed direct C–H arylation. In the presence of a catalytic amount of Pd(OAc)2, P(t-Bu3)·HBF4, and an excess of Cs2CO3, the C–H arylation of TTF with several aryl bromides bearing 1,3-dithiol-2-ylidenes took place efficiently to produce the corresponding π-conjugated molecules. We also succeeded in the estimation of the oxidation potentials and number of electrons involved in each oxidation step of the obtained compounds by digital simulations.

Introducere. Bezoarul este un conglomerat alcătuit din material parţial digerabil sau nedigerabil impactat la nivelul stomacului. Tricobezoarul (aglomerările de păr) apare cel mai frecvent la pacienţii cu tulburări psihice (tricotilomanie) şi reprezintă o patologie rară care poate determina dificultăţi diagnostice si terapeutice. Material şi metodă. Prezentăm un caz de tricobezoar gastric la o pacientă in varsta de 12 ani, fără antecedente personale patologice, internată pentru epigastralgii şi vărsături alimentare. Examenul clinic relevă la palparea abdomenului o formaţiune epigastrică de aprox. 5/3cm, dură, imobilă, aderentă de planul profund la care examenele de laborator relevă doar o uşoară anemie hipocromă microcitară. Endoscopia digestivă superioară vizualizează tricobezoar gigant de aprox 17 cm, vizibil din zona subcardială până în regiunea antrală, fixat cu un fir de păr de o zonă cu aspect inflamator pseudopolipoid, situata prepiloric. Pacienta a fost dirijată către serviciul de chirurgie pediatrică, întrucât dimensiunea tricobezoarului nu a permis extragerea pe cale endoscopică. S-a tentat initial extragere prin abord laparoscopic, care nu a reuşit si a impus laparotomie minimă subcostală stângă, gastrotomie cu evacuarea tricobezoarului gastric. Postoperator evoluţie favorabilă. Discuţii. Cu toate că prevalenţa la om este scăzută, mortalitatea poate atinge în anumite cazuri 30%, datorită sângerărilor, obstrucţiei, peritonitei sau eventualei perforaţii gastrointestinale ce pot apărea. Diverse metode endoscopice au fost raportate pentru extragerea bezoarului, precum litotripsie cu unde şoc, îndepărtare prin aspirare folosind endoscop cu canal larg de lucru, extracţie cu ansă de polipectomie şi forceps de biopsie. Concluzie. Raritatea acestei patologii în populaţia pediatrică impune un diagnostic diferenţial atent. Dificultăţile terapeutice se datorează dimensiunilor tricobezoarului, iar prognosticul depinde de patologia psihiatrică subiacentă.

Diabetes mellitus is a common chronic systemic disorder characterised by hyperglycaemia as a standard feature. A traditional plant known as Abrus precatorius (AP) has been used for the treatment of type II diabetes mellitus in Malaysia. The potential of the 80% methanolic extract of A. precatorius leaves has been tested in vitro for its α-glucosidase inhibition and its glucose diffusion activity. It was observed that the extraction of A. precatorius leaves exhibit a high α-glucosidase inhibition at the concentrations of 25 and 50 mg/mL (65.4% and 84.6%), respectively, but low inhibition at the concentration of 6.25 to 12.5 mg/mL (25% and 28.2%) when compared to control. Meanwhile, the methanolic extract of A. precatorius slightly affected the glucose diffusion at the concentration of 50 mg/mL (9.5%) within 24 h compared to the control group. These results indicated that the methanolic extract of A. precatorius leaves is capable of inhibiting α-glucosidase activity, besides halting glucose diffusion activity by delaying the glucose absorption in the gut.
TOTAL IMPACT EVALUATION OF TRANSPORTATION SYSTEMS
Authors: Rohács József , Rohács Dániel
Published: May 2020

Impact assessment, in general, includes the environmental safety and security considerations,
and cost/cost-benefit analysis of the used sources. As usual, the impact is evaluated at two levels: (1) impact during
operation (usage) related to a chosen operational unit (e.g., running distance [km], operational time [h] or calendar
time [h]), (2) the life-cycle (project life-cycle) impact. The environmental impact is characterized by the chemical
and noise emissions. Safety and security are estimated by risks. Costs are calculated based on the required financial
support and caused losses. All these calculations are related to the individual vehicles or vehicles with average
behaviours. The investigation of sustainability impact requires a wider evaluation and approach, for example, by also
including production and recycling beside the operational aspects. This paper generalizes the impact analysis. At first,
it considers all types of impacts including the direct (e.g., accidents) and indirect long-term effects (e.g., health
problems caused by emissions). All the impacts are expressed as costs. The defined Sustainable Transportation
Performance Index (STPI) is the Total Life-Cycle Cost (TLCC) related to the unit of transport work. As such, it
combines the life-cycle emissions evaluation and transport costing methods. It contains the total operational and
total impact costs. The proposed approach introduces three new specific features in the impact analysis: (1) the
impact is evaluated on the transportation system level, (2) the impact is estimated as the total value (including
all the related sub-systems and elements, like vehicles, transport infrastructure, transport flow control, etc.),
(3) proposes a unique index to describe the total impact. The paper describes the general equations and the developed
methodology for the estimation of the total impact and analyses its applicability. The preliminary results demonstrate
the applicability of the defined index and its evaluation methodology. It also shows the limitations of traditional
cost models. Further test results and wider application of the methodology will be provided in a series of follow up
papers by the research team.
Plasma β Dependence of Density, Temperatures, and Magnetic-field Correlations of Mirror Structures: Observation and Theory
Authors: Hau L.-N. , Chang C.-K.

The mirror structures identified by the depressed or enhanced magnetic field associated with the enhanced or depressed plasma density are widely observed in the solar system plasma. These structures are generated by the mirror instability as a result of sufficiently large temperature anisotropy of T
⊥ > T
∥. Here, T
⊥ and T
∥ are, respectively, to be the temperatures perpendicular and parallel to the magnetic field and β = p/(B
2/2μ
0). Two important observed characteristics are the uneven density-magnetic field compressibility, defined as

, among the various mirror events, and the anticorrelation between the temperatures and magnetic field. This study first shows two mirror structures observed in the magnetosheath with distinct β and

. Specifically, β ∼ 6.67,

and β ∼ 1.44,

. The linear kinetic theory is adopted to derive the phase relations for the mirror instability which show an inverse relation between

and

, which are negative for various parameter values, and β. While the correlation

may be negative or positive for the mirror unstable and stable parameter regimes, respectively. The theoretical analyses are consistent with the observational results that δT

δB < 0 for both events and δT
∥
δB < 0 is more pronounced for the high β case. The statistical analysis results are summarized by the relationships between
