OPTIMIZATION OF FLUSHING PRESSURE, TIME, ACID AND CHLORINE TREATMENT ON DRIP EMITTER RECOVERY USING TREATED EFFLUENT
Authors: Sesani Priscilla , Okwany Romulus , Nyakach Samwel
Published: November 2022

The competitive water uses and demand for freshwater increase the vulnerability of water sources. Due to the resulting water scarcity, reclamation of wastewater has been shown as an alternative and a viable water supply source for critical food security. The utilization of wastewater in agriculture is more compatible with drip irrigation but challenged with system clogging. Flushing pressure and chemical treatments were investigated with regards to the recovery of clogged emitters operated with treated blackwater effluent. A set of orthogonal experiments with flushing pressure, time, acid contact time and chlorine contact time were used to study the emitter recovery of in-line labyrinth drippers. Water discharge rates were measured and characterized at 72-hour intervals. Physicochemical and biological water analyses were carried out to determine parameters triggering clogging. The results showed that the flushing treatments had a significant effect on clog removal and recovered the discharge rates by 98% of the initial flow. Among the four factors, acid removed the built-ups the most. This was a clear indication that clogging in this study was mainly due to the chemical precipitation of Fe, Ca2+ and pH of the wastewater. Coarse particles could easily wear down, but not so much for biological growth induced by the biochemical water parameters. The analysis of variance indicated that the flushing pressure had a significant effect on the discharge of the precipitates that were dislodged by acid in contact, resuscitating the emitter discharge. The pressure provided a flushing velocity of 0.28 m/s and 0.49 m/s, removing the clogging particles. The flushing treatments implemented in the study improved the relative emitter discharge, uniformity coefficient (Uc) and the Emitter Discharge Variation (Dra). This study provides relevant information on emitter operational recovery for uniform water application and management of drip irrigation system (DIS) using wastewater.
Social Network Analysis in Wood Industry Projects
Authors: Novotni Adrienn , Pásztory Zoltán , Tóth Zsolt
Published: November 2022

The study analysed H2020 projects in the wood industry using SNA methods. It was mainly performed using R. Based on the data set from CORDIS, an adjacency matrix was constructed and used to plot the network of project participants. Various network indicators were then calculated. In search of notable distributions in network research, several statistical methods (maximum likelihood, Kolmogorov-Smirnov test, moments, bootstrapping) were used to perform a goodness-offit analysis on the frequencies of the degrees to verify randomness or scale-freedom. The small-world nature was also investigated. The results show that the distribution of the degrees of project participants reflects multiple effects, whereas the number of project participations per project participant follows a power distribution; thus, the scale-freedom that has been emphasised in many scientific analyses is observed. The network indicators show that the network is not small-world, with a high number of Finnish participants among the central actors.
Comparative Analysis of Ice Break Damage in Two Börzsöny Mountain Valleys in Hungary in 2014 Based on Airborne Laser Scanning
Authors: Molnár Tamás , Király Géza
Published: November 2022

Severe mechanical damage from frost and ice on trees occurred in the Börzsöny Mountains in Northern Hungary during 1–2 December 2014. The frost and ice affected 10,000 hectares overall; however, the two examined valleys suffered conspicuously different extents of damage. While the Rakottyás Valley study area had severe damage, the Pogány-Rózsás Forest Reserve suffered only moderate damage. Airborne Laser Scanning (ALS) and a field survey were utilised to assess the damage. Digital Surface Modell (DSM), Digital Terrain Model (DTM), and Normalised Digital Surface Modell (nDSM) were calculated from the dense point cloud in 3D. Elevation, slope and aspect were derived to describe site conditions. Damage thresholds were set for the ALS data (tree height < 5 m) and the ground-based damage (frequency > 90%). These were compared in a confusion matrix on a pixel scale, which showed partial agreement due to different sampling methods and ranges but also indicated that Rakottyás was more damaged (54.35% of the area) than Pogány-Rózsás (36.7%). The Total Accuracy was 0.54.

This paper presents an assessment of the levels of total harmonic distortion (THD) in buck-boost DC-AC converters using triangular wave and saw-tooth unipolar based-modulation schemes. This paper seeks to identify a better technique for mitigating the total harmonic distortion on buck-boost DC-AC converters under unipolar carrier-based modulation schemes. This was achieved by subjecting the buck-boost DC-AC converter under triangular wave-based and saw-tooth based-unipolar modulation schemes. The voltage and current output of the buck- boost DC-AC converter under each scheme was analysed using a power GUI Fast Fourier Transform (FFT) analytical tool resident in the MATLAB Simulink environment unlike with the conventional scheme of computing the percentage of THD. The test system was obtained by a combination of DC-DC buck-boost converter, H-bridge based-insulated unipolar gate transistors, and a logic control unit. It was realized that THD of 0.2865%, peak output voltage of 294.1V and current of 9.805A were obtained by using the saw-tooth based-unipolar modulation scheme, whereas a THD of 0.1479%, peak output voltage of 297.4V and current of 9.53A were obtained by using the triangular wave based-bipolar modulation scheme on the same Buck-boost DC-AC converter circuit. The results imply a high power factor utilization and low power loss in the triangular wave based-unipolar modulation scheme compared to the saw-tooth based-unipolar modulation technique for improving the performance characteristics of the buck-boost converter system. This study showed that power drives and heavy load machines based-power electrical loads are required to use the saw-tooth based-unipolar modulation (STBUM) scheme for high current and low THD%, whereas sensitive power electrical loads such as hospital equipment and communication industries based-power electronic devices are required to use the triangular wave-based unipolar modulation (TWBUM) scheme due to low current and THD%.

Published: November 2022

Das freiwillige Programm zur Lärmsanierung an bestehenden Schienenwegen der Eisenbahnen des Bundes von 1999 hat seine rechtliche Grundlage im Bundeshaushaltsgesetz. Die Lärmaktionsplanung von 2008 auf Grundlage der Richtlinie 2002/49/EG des Europäischen Parlaments und des Rates über die Bewertung und Bekämpfung von Umgebungslärm ist im Bundesimmissionsschutzgesetz verankert. Beide Regelwerke verfügen über unterschiedliche Parameter bei der Bewertung von Lärm. In der öffentlichen Wahrnehmung lösten die abweichenden Kriterien sowie die Folgenlosigkeit der Lärmaktionsplanung immer wieder Irritationen aus. Die Harmonisierung der Instrumente Lärmsanierungsprogramm und Lärmaktionsplanung war Gegenstand des Koalitionsvertrags von 2018 und aus fachlicher Sicht geboten.

 

Vor diesem Hintergrund hat das Bundesministerium für Digitales und Verkehr das Projekt „Harmonisierung der Lärmsanierung und Lärmaktionsplanung“ initiiert, das vom Eisenbahn-Bundesamt geleitet und von einem Arbeitskreis mit Vertretungen von Bundesländern, Kommunalverbänden, der Wissenschaft, Fachverbänden und Bürgerinitiativen begleitet wurde. Im Ergebnis konnte gezeigt werden, dass die Bewertungsparameter der Lärmsanierung auf die der Lärmaktionsplanung umgestellt werden können, ohne dass sich die bisherigen Priorisierungen der Lärmsanierungsabschnitte zum Nachteil der Anliegerinnen und Anlieger verschieben würden. Voraussichtlich ab 2025 soll die Priorisierung der Lärmsanierungsabschnitte durch die DB Netz AG als Infrastrukturbetreiber des Schienennetzes des Bundes auf Basis der Ergebnisdaten der Lärmkartierung vorgenommen werden.
Enhanced electronic transport properties of Te roll-like nanostructures
Authors: Viana E R , Cifuentes N , González J C
Published: November 2022

In this work, the electronic transport properties of Te roll-like nanostructures were investigated in a broad temperature range by fabricating single-nanostructure back-gated field-effect-transistors via photolithography. These one-dimensional nanostructures, with a unique roll-like morphology, were produced by a facile synthesis and extensively studied by scanning and transmission electron microscopy. The nanostructures are made of pure and crystalline Tellurium with trigonal structure (t-Te), and exhibit p-type conductivity with enhanced field-effect hole mobility between 273 cm2/Vs at 320 K and 881 cm2/Vs at 5 K. The thermal ionization of shallow acceptors, with small ionization energy between 2 and 4 meV, leads to free-hole conduction at high temperatures. The free-hole mobility follows a negative power-law temperature behavior, with an exponent between −1.28 and −1.42, indicating strong phonon scattering in this temperature range. At lower temperatures, the electronic conduction is dominated by nearest-neighbor hopping (NNH) conduction in the acceptor band, with a small activation energy ENNH ≈ 0.6 meV and an acceptor concentration of NA ≈ 1 × 1016 cm−3. These results demonstrate the enhanced electrical properties of these nanostructures, with a small disorder, and superior quality for nanodevice applications.

POETICS OF REUSE OF THE HISTORICAL HERITAGE: THREE CASE STUDIES OF EPHEMERAL ARCHITECTURE IN VENICE
Authors: Zorzetto Alessandro , Barrios Padura Ángela , Molina Huelva Marta , Marzo Mauro
Published: November 2022

The archetype of the vessel, declined ontologically as heterotopia and etymologically as trait d’union of a community, becomes the pretext to propose the restoration of Venice’s citizenship through a “poetics of reuse”. The relationship between ephemeral architecture and historical heritage is analysed according to the three criteria identified by Pierre Pinon. The concept of reutilisation is declined through building materials. Reconversion is identified through examples of radical change of use of historic military buildings. Reappropriation is associated with the temporary expansion of the potential of public space through architectural installations. Case studies corresponding to each category are identified, and from the primary sources the three-dimensional redesign of these projects is contextualised in the historical surroundings, in order to deduce considerations regarding the relationship between the two frameworks. Since the case studies are very extensive and rather heterogeneous, the novelty lies in the transversal reading approach that returns the Biennale’s magnificent centenary activity directly to the city and its inhabitants, subverting the negative connotation that cultural tourism has acquired on the island. The research aims to create an atlas of ephemeral architecture, define a taxonomy and draw up a document containing guidelines for future experiences of ephemeral architecture in the city.
Complex Organic Molecules Detected in 12 High-mass Star-forming Regions with Atacama Large Millimeter/submillimeter Array
Authors: Baek Giseon , Lee Jeong-Eun , Hirota Tomoya , Kim Kee-Tae , Kyoung Kim Mi
Published: November 2022

Recent astrochemical models and experiments have explained that complex organic molecules (COMs; molecules composed of six or more atoms) are produced on the dust grain mantles in cold and dense gas in prestellar cores. However, the detailed chemical processes and the roles of physical conditions on chemistry are still far from understood. To address these questions, we investigated 12 high-mass star-forming regions using Atacama Large Millimeter/submillimeter Array (ALMA) Band 6 observations. They are associated with 44/95 GHz class I and 6.7 GHz class II CH3OH masers, indicative of undergoing active accretion. We found 28 hot cores with COM emission among 68 continuum peaks at 1.3 mm and specified 10 hot cores associated with 6.7 GHz class II CH3OH masers. Up to 19 COMs are identified including oxygen- and nitrogen-bearing molecules and their isotopologues in cores. The derived abundances show a good agreement with those from other low- and high-mass star-forming regions, implying that the COM chemistry is predominantly set by the ice chemistry in the prestellar core stage. One clear trend is that the COM detection rate steeply grows with the gas column density, which can be attributed to the efficient formation of COMs in dense cores. In addition, cores associated with a 6.7 GHz class II CH3OH maser tend to be enriched with COMs. Finally, our results suggest that the enhanced abundances of several molecules in our hot cores could be originated by the active accretion as well as different physical conditions of cores.

Revealing the formation, dynamics, and contribution to plasma heating of magnetic field fluctuations in the solar wind is an important task for heliospheric physics and for a general plasma turbulence theory. Spacecraft observations in the solar wind are limited to spatially localized measurements, so that the evolution of fluctuation properties with solar wind propagation is mostly studied via statistical analyses of data sets collected by different spacecraft at various radial distances from the Sun. In this study we investigate the evolution of turbulence in the Earth’s magnetosheath, a plasma system sharing many properties with the solar wind. The near-Earth space environment is being explored by multiple spacecraft missions, which may allow us to trace the evolution of magnetosheath fluctuations with simultaneous measurements at different distances from their origin, the Earth’s bow shock. We compare ARTEMIS and Magnetospheric Multiscale (MMS) Mission measurements in the Earth magnetosheath and Parker Solar Probe measurements of the solar wind at different radial distances. The comparison is supported by three numerical simulations of the magnetosheath magnetic and plasma fluctuations: global hybrid simulation resolving ion kinetic and including effects of Earth’s dipole field and realistic bow shock, hybrid and Hall-MHD simulations in expanding boxes that mimic the magnetosheath volume expansion with the radial distance from the dayside bow shock. The comparison shows that the magnetosheath can be considered as a miniaturized version of the solar wind system with much stronger plasma thermal anisotropy and an almost equal amount of forward and backward propagating Alfvén waves. Thus, many processes, such as turbulence development and kinetic instability contributions to plasma heating, occurring on slow timescales and over large distances in the solar wind, occur more rapidly in the magnetosheath and can be investigated in detail by multiple near-Earth spacecraft.

Published: November 2022

We have collected a new deep Chandra X-Ray Observatory exposure of PSR B2224+65 and the “Guitar Nebula,” mapping the complex X-ray structure. This is accompanied by a new Hubble Space Telescope (HST) Hα image of the head of the Guitar. Comparing the HST and Chandra structures in four epochs over 25 yr, we constrain the evolution of the TeV particles that light up the filament. Cross-field diffusion appears to be enhanced, likely by the injected particles, behind the filament’s sharp leading edge, explaining the filament width and its evolving surface brightness profile.

Published: November 2022

The Webb’s hyacinth (Bellevalia webbiana Parl., Asparagaceae) is an Italian narrow endemic species, listed as Endangered (EN A2c) in the IUCN Global Red List of Threatened Species. The range of this bulbous perennial herb is restricted to two disjunct areas of Central Italy, separated by the mountain ridge of Northern Apennine. To evaluate the impact of climate change on this species, we used Ecological Niche Modelling (ENM) to predict future potential distribution under different scenarios, through Maximum entropy algorithm. The estimated potential distribution highlights the vulnerability of Webb’s hyacinth to the effects of climate change. The current potential Area Of Occupancy (AOO) (992 2×2 km cells) is forecast to dramatically decrease in the range 2041–2100, under the scenarios SSP3-7.0 (2070 = –249, 2100 = –682) and SSP5-8.5 (2070 = –372, 2100 = –948). In all future scenarios, the predicted potential distribution shifts towards higher elevations, located in the two main areas in which the species currently occurs. This could imply a loss of the current genetic differentiation documented at the population level. To overcome these problems, in addition to assisted colonization, an ex situ conservation programme should be planned.
Job change in the conditions of precarious work (on the example of the Republic of Bashkortostan permanent residents)
Authors: Turakayev Marcel S.
Published: November 2022

Job and profession change are basic forms of social and labour mobility. Unstable working conditions are typical for less developed in socio-economic terms regions. The purpose of the study is to identify the degree of influence of precarious employment and other socio-demographic and economic factors on the probability of job change among Bashkortostan residents. The empirical basis of the study is a sociological survey of the Republic of Bashkortostan population. According to the results obtained, such factors as working in a private enterprise, self-employment, short work experience and the presence of a temporary employment contract increase the likelihood of job change. Income satisfaction, official wage and the absence of credit debt reduce the probability of job change. Respondents who want to improve their level of education and qualifications, as well as those who do not work within their specialty, tend to change their place of work more often. The conducted research has shown that changing a job, as a rule, does not contribute to improving the financial situation and working conditions of respondents.
La collaboration balzacienne pour Babel : Pierre Grassou et la propriété littéraire
Authors: Matsumura Hiroshi
Published: November 2022

En 1839, Balzac devient président de la Société des Gens de Lettres, dont il est l’un des instigateurs. Par la suite, il dirige la publication d’un ouvrage collectif dont les contributeurs sont les membres de la Société. Le deuxième des trois volumes publiés en 1840 sous le titre général de Babel accueille un texte de Balzac, Pierre Grassou , une nouvelle qui raconte le sort d’un peintre médiocre pris dans le milieu de la société bourgeoise. Cette création du romancier est l’aboutissement d’une longue réflexion sur la propriété littéraire et le statut des écrivains de ce temps, réflexion amorcée par une Lettre adressée aux écrivains français du xix e  siècle publiée en 1834. Nous tâcherons de cerner la pensée de Balzac qui sous-tend le projet de cet ouvrage collectif, en focalisant notre analyse sur Pierre Grassou , qui contient à notre sens un constat du romancier sur l’état des artistes et sur la propriété des œuvres d’art dans une société dominée par l’argent.
Balzac et Janin, de la connivence à la concurrence
Authors: Beliaeva Solomon Maria
Published: November 2022

Cet article se propose de revenir sur les différentes formes qu’a pu prendre la collaboration entre Balzac et Janin, de part et d’autre de la célèbre théorisation balzacienne de « l’école du désenchantement », par laquelle ce dernier s’associait à Janin, Nodier et Stendhal, en janvier 1831. En-deçà du collectif fantasmé par Balzac, son éphémère collusion avec Janin permet de mettre en lumière la relation paradoxale de deux jeunes auteurs, unis par leur maniement, aussi habile que coordonné, de nouveaux mécanismes de publicité littéraire.
Élaboration, collaboration et prostitution
Authors: Vanoncini André
Published: November 2022

Balzac apparaît d’un côté comme l’instance centrale de sa production alors que, de l’autre, il peut se scinder et se dédoubler en d’innombrables figures suppléantes. Cette dialectique, il la présente à plusieurs niveaux de sa démarche. Dans ce contexte, il soulève la question de l’appartenance de son écriture à un discours préalable. Il sait que, même en dehors d’une collaboration ou référence assumée, le travail de l’écrivain implique toujours qu’il soumette sa créativité à des contraintes formelles et thématiques, voire commerciales. Ainsi, l’inévitable dimension transindividuelle de sa création – qu’il désire pourtant vierge de déterminismes extérieurs – peut lui sembler voisine de la prostitution.
Les interventions de Charles Rabou dans Les Petits Bourgeois
Authors: Kamada Takayuki
Published: November 2022

Roman inachevé de grande importance, Les Petits Bourgeois (tout comme Le Député d’Arcis ) a été « terminé » par Charles Rabou, ancien collaborateur de Balzac, après la mort du romancier et suivant les vœux de sa veuve. Cette version apocryphe fait l’objet de quelques publications entre 1854 et 1864. Les critiques et éditeurs modernes l’écartent systématiquement au profit de la version originale de Balzac reconstituée à partir des documents authentiques conservés. Pourtant, nous aurons intérêt à nous interroger sur les interventions de Rabou, afin de voir comment il a essayé de mettre en œuvre (en triant, abandonnant, réorientant) les multiples possibles romanesques qu’envisageait Balzac sans parvenir à les explorer véritablement dans son texte en devenir. Ceci pour repenser la difficulté des enjeux de son roman interrompu, à la lumière du travail « accompli », mais inévitablement réducteur, de son coopérateur post-mortem .
La Peau de chagrin : l’énergie de l’écriture
Authors: Borderie Régine
Published: November 2022

La Peau de chagrin contient diverses formes de personnifications qui contribuent à l’énergie de l’écriture : elles mettent en action l’abstrait ou l’inanimé, ou présentent un personnage sujet d’action comme l’incarnation d’une idée abstraite, et par là se donnent ou donnent à voir. Toutefois les personnifications ne relèvent pas seulement de la rhétorique dans ce roman, mais aussi de la philosophie, de la psychologie, de la physio-psychologie et de la magie. Et si elles manifestent la vitalité de l’idée, elles montrent également le pouvoir de la destruction.
Balzac ou les ambiguïtés
Authors: Lorant André
Published: November 2022

Dans le courant de décembre 1835, Balzac confie à ses secrétaires, Auguste de Belloy et Ferdinand de Grammont, le soin de réviser ses premiers romans (1822-1824), à l’exception de ceux écrits en collaboration avec Lepoitevin de L’Égreville, et de les faire entrer dans les Œuvres complètes de feu Horace de Saint-Aubin , à paraître chez Hippolyte Souverain. Comment l’auteur a-t‑il pu accepter que ces jeunes gens dévoués mais sans génie défigurent ses textes, qu’ils ne se contentent pas de les adapter au goût du jour mais encore qu’ils remanient des fragments significatifs de ses premières intentions et de sa vision du monde ? C’est la question complexe à laquelle je tente de répondre de manière satisfaisante en l’état actuel de nos connaissances. Un examen attentif de Vie et malheurs de Horace de Saint-Aubin , biographie fictive composée sous le regard de Balzac par Jules Sandeau, publiée dans les tomes I et II de l’édition Souverain, est propre à apporter quelques éléments de réponse. L’auteur d’ Eugénie Grandet et du Père Goriot repousse Horace, ce littérateur provincial raté en qui il découvre un possible alter ego s’étant aventuré prématurément dans l’art romanesque. « Il avait écrit avant d’avoir vécu », selon la formule heureuse de Sandeau. De ce point de vue, Vie et malheurs est un poignant document du désenchantement et une autoflagellation sans merci que Balzac s’inflige.
Le château de l’Héritière
Authors: Gautier Jean-Jacques
Published: November 2022

L’identification du château de L’Héritière de Birague (1822) à l’authentique château de Brézé, près de Saumur, témoigne du sens architectural d’Honoré Balzac, alias Lord R’Hoone, dans la mise en scène du roman frénétique qui use d’un vocabulaire gothique, tout en déployant une intrigue inscrite dans une véritable topographie palimpseste. Cette topographie fantomatique est analysée ici afin de la comparer au véritable château de Brézé, que Balzac a pu visiter à la fin de l’été 1820. Il l’a gardée à l’esprit en écrivant au second semestre 1821 L’Héritière de Birague. C’est un parfait exemple de ce que fera ensuite l’auteur de La Comédie humaine .

Authors: Pinc Mariana Moraes , Baisch Rossely Gimenes , Lastra Regiane Urcoviche , Silva Camila da , Jacomassi Ezilda , Alberton Odair
Published: November 2022

This study aimed to evaluate the yield and chemical composition of essential oil (EO) and the growth parameters of Melissa officinalis L. (lemon balm) inoculated with arbuscular mycorrhizal fungi (AMF) under different rates of phosphorus (P). Treatments comprised a high and low P rate combined or not with inoculation of Rhizophagus clarus (C. Walker & A. Schüßler) or Claroideoglomus etunicatum (C. Walker & A. Schüßler), arranged according to a 2 × 3 factorial design with 8 replications. At 4 months after transplanting, shoot fresh and dry weights increased in both AMF-inoculated treatments under a low P rate. There was an increase in shoot P content with C. etunicatum inoculation under a high P rate. EO yields ranged from 0.04% to 0.12% and increased with R. clarus inoculation. Eighteen compounds were identified in EOs. The major components were geranial (43.96%–54.93%), neral (29.95%–34.66%), geraniol (3.11%–12.85%), and (E)-caryophyllene (2.62%–6.66%). It was concluded that AMF inoculation increased plant growth, improved EO yield, and modified EO composition. It is recommended to inoculate lemon balm with R. clarus under low P rates.
Spatial properties and the influence of the Soret coefficient on the solutions of time-dependent double-diffusive Darcy plane flow
Authors: Chen Xuejiao , Li Yuanfei
Published: November 2022

This paper investigates time-dependent double-diffusive Darcy flow which is defined in a semi-infinite strip pipe, where the generatrix of the pipe is not parallel to the coordinate axis any more. By using several results which have been derived in the literature, the spatial properties and the influence of the Soret coefficient on the solutions are both obtained. We also give some concrete examples.
Vanishing viscosity limit of incompressible flow around a small obstacle: A special case
Authors: You Xiaoguang
Published: November 2022

In this paper, we consider two dimensional viscous flow around a small obstacle. In [4], the authors proved that the solutions of the Navier-Stokes system around a small obstacle of size $ \varepsilon $ converge to solutions of the Euler system in the whole space under the condition that the size of the obstacle $ \varepsilon $ is smaller than a suitable constant $ K $ times the kinematic viscosity $ \nu $. We show that, if the Euler flow is antisymmetric, then this smallness condition can be removed.

Published: November 2022

Spectra of network related graphs have numerous applications in computer sciences, electrical networks and complex networks to explore structural characterization like stability and strength of these different real-world networks. In present article, our consideration is to compute spectrum based results of generalized prism graph which is well-known planar and polyhedral graph family belongs to the generalized Petersen graphs. Then obtained results are applied to compute some network related quantities like global mean-first passage time, average path length, number of spanning trees, graph energies and spectral radius.
