The harmonization issue in laboratory medicine: the commitment of CCLM
Authors: Zaninotto Martina , Graziani Maria Stella , Plebani Mario 
Published: November 2022

Abstract
The analytical quality of the clinical laboratory results has shown a significant improvement over the past decades, thanks to the joint efforts of different stakeholders, while the comparability among the results produced by different laboratories and methods still presents some critical issues. During these years, Clinical Chemistry and Laboratory Medicine (CCLM) published several papers on the harmonization issue over all steps in the Total Testing Process, training an important number of laboratory professionals in evaluating and monitoring all the criticisms inherent to the pre-analytical, as well as analytical and post analytical phases: from the consensus statement on the most informative testing in emergency setting, to the prevention and detection of hemolysis or to patients identification and tube labeling procedures, as far as to different approaches to harmonize hormones measurements or to describe new reference methods or to harmonize the laboratory report. During these years the commitment of the journal, devoted to the harmonization processes has allowed to improve the awareness on the topic and to provide specific instruments to monitor the rate of errors and to improve patients safety.
Coagulation activity of liquid extraction of Leucaena leucocephala and Sesbania grandiflora on the removal of turbidity
Authors: Putra Rudy Syah , Nasriyanti Desi , Sarkawi Muhammad 
Published: November 2022

Abstract
Turbidity is removed by adding a chemical coagulant, which produces a secondary toxic of alumina residues in the water. Therefore, the aim of study was to evaluate the coagulation activity of NaCl extract from Leucaena leucocephala and Sesbania grandiflora seeds on the removal of turbidity for water purification. The proximate composition of the seeds was determined. Fourier transform infrared spectroscopy was used to identify the functional groups of protein, and the surface morphology was observed by SEM-EDS. To obtain the optimized condition, all experiments were evaluated by artificial turbid water before being applied on the natural water (i.e., Selokan Mataram). The coagulation process was evaluated by concentration (M), dosage (mL/L), and pH in terms of turbidity, total dissolved solids, and transmittance of light. The results showed that both coagulant seeds contained 25.32 and 30.81% of protein. These coagulants could remove the turbidity by 99.7% for L. leucocephala and 94.24% for S. grandiflora from artificial turbid water at the optimized concentration of 1.0 M, and dosage of 5 and 10 mL/L, respectively. At pH 5 the removal of turbidity from Selokan Mataram was 99.4% for L. leucocephala and 97.23% for S. grandiflora.
Numerical simulation and mathematical modeling of the casting process for pearlitic spheroidal graphite cast iron
Authors: Şensoy Abdullah Tahir 
Published: November 2022

Abstract
Fluidity, an essential parameter in casting operations, is influenced by the thermal properties of the alloy and the mold, pouring temperature, modification, and inoculation of the alloy. In this work, pearlitic spheroidal graphite cast iron (PSGI) was studied in terms of fluidity characteristics. The sand mold used had different section thicknesses. The alloy was cast at pouring temperatures changing between 1,360–1,480°C. Liquid metal quality ranged between 10 and 90% where the section thickness was changed from 1 to 5 mm. FlowCast simulation tool was used for the modeling of the tests. The analysis of variance results of the response surface model constructed between certain casting parameters and fluidity length have shown that the reduced regression equation is very accurate in terms of statistical indicators (predicted R
2: 0.99). The sensitivity analysis has shown that the section thickness is the most dominant parameter on the fluidity, while metallurgical quality is the least. The proposed model was also compared with the studies in the literature and it was seen that the results are well-matched. Therefore, it was suggested to use the proposed equation in order to estimate the fluidity results of PSGI without the need for real casting operations.
Lucretius’prolepsis
Authors: Rover Chiara 
Published: November 2022

AbstractThis paper aims to investigate the equivalent of Epicurus’ πρόληψις, the second criterion of the Epicurean Canonic (DL X 31 = fr. 35 Usener), in Lucretius’De rerum natura(DRN). Taking stock of the several occurrences of the Latin termsnotitiaandnotitiesin the six books of the poem, I show that Lucretius’ view about preconception remains faithful to Epicurus’ πρόληψις, and that the poet does not endorse a less empiricist position than his Master because of some influence of the Stoic ἔννοια. To this end, I will also briefly address an important case in which πρόληψις, albeit not clearly mentioned, plays an essential role, namely theprolepsisof the deity (DRNV 1169–1182). Finally, I explain how Lucretius can be of some help in grasping the controversial relationship between the criterion of πρόληψις and that of ἐπιβολὴ τῆς διανοίας (animi inectus/iactus), showing in which way the poet seems to consider the latter as a criterion of truth in its own right.
Reminiscenze di Aristotele,MetafisicaIX 6.1048b18–35 in autori neoplatonici
Authors: Linguiti Alessandro 
Published: November 2022

AbstractIn Proclus’Platonic Theology(V 17, 62. 22–63. 2) one can detect a clear recollection of the well-known and much discussed passage 1048b18–35 fromMetaphysicsIX 6. This passage is transmitted in only one branch of the manuscript tradition and some scholars maintain that it is not by Aristotle or that it does not belong to hisMetaphysics. On the other hand, Proclus’ testimony, supported by other passages by Neo-Platonic authors, provides an argument for the original location of the discussed section in Aristotle’sMetaphysics.
The Antecedents to Habitual Entrepreneurship: Exploring the Role of Entrepreneurs’ Narcissism and Educational Level
Authors: Leonelli Simona 
Published: November 2022

Abstract
This paper aims to analyze the antecedents leading to habitual entrepreneurship by investigating the role of entrepreneurs’ narcissism and their level of education. While the literature provides a general understanding of what motivates individuals to pursue their entrepreneurial ideas, the possible antecedents to the individual’s decision to become a habitual entrepreneur remain unexplored and untested. Relying on a sample of 343 start-up entrepreneurs, hypotheses are tested through the partial least squares analysis. Results show that entrepreneurs’ educational levels fully mediate the relationship between narcissism and the choice to become habitual entrepreneurs. The study contributes to the literature on entrepreneurs’ personality, decision-making, and human capital, also underlining a few practical implications.
Wo steht die Friedensbewegung und was steht an?
Authors: Leistner Alexander 
Published: November 2022

ZusammenfassungDer erneute russische Angriff auf die Ukraine hat zeitweilig auch das öffentliche Interesse auf die Friedensbewegung gelenkt und fragen lassen, ob es diese noch gibt und ob ihr über den Weg zu trauen ist. Das Interesse verrät zugleich etwas über die Bedeutung dieser für die bundesrepublikanische Geschichte so wichtigen Protestbewegung. Der Beitrag versucht eine Bestandsaufnahme der deutschen Friedensbewegung. Dabei wird zunächst die Doppelgeschichte der Friedensbewegung in Ost- und Westdeutschland umrissen, sowie die Entwicklung seit 1989. Der Text gibt einen Überblick über die Bandbreite von Organisations- und Aktionsformen und unterscheidet idealtypisch drei Handlungsschwerpunkte der zurückliegenden Jahrzehnte. Im letzten Teil wird beleuchtet, wie die Friedensbewegung auf den russischen Angriffskrieg reagiert hat und was aktuelle Herausforderungen der Bewegung sind.
Die Zukunft des Multilateralismus und der OSZE und die Bedeutung der Zivilgesellschaft
Authors: Greminger Thomas , Holewiak Klaudia Anna 
Published: November 2022

Zusammenfassung
Die Welt steht vor einer unvorhergesehenen Krise mit dem Auftreten mehrerer regionaler Konflikte und dem Einmarsch Russlands in die Ukraine. Vor diesem Hintergrund erörtert dieser Artikel, wie Europas Sicherheit sich nach dieser Krise entfalten könnte. Er unterstreicht hierbei, dass die gegenwärtigen Herausforderungen für den europäischen Sicherheitsdialog die europäischen Staaten dazu auffordern, gemeinsam mit der OSZE die diplomatischen Beziehungen und die Zusammenarbeit zu stärken. Die Situation in Europa und dessen enge zwischenstaatliche Verflechtung betont zudem die Notwendigkeit und den Bedarf an Reformen, besonders im Sicherheitsbereich. Ferner ist es von entscheidender Bedeutung, sich in den Friedensbemühungen auf historische Entwicklungen zu stützen. In Anbetracht der aktuellen Situation werden die Lehren aus den Helsinki-Vereinbarungen und die Stärkung bestehender Rahmenwerke sich als entscheidend erweisen bei der Förderung von Frieden sowie von regionaler und internationaler Sicherheit und Zusammenarbeit. Die Rolle der zivilgesellschaftlichen Organisationen ist hierbei von zentraler Bedeutung, da sie eine Fülle wertvoller Informationen und Forschungsanalysen bereitstellen, die einen entscheidenden Beitrag dazu leisten, Anliegen von Konflikten betroffener Regionen und der internationalen Gemeinschaft als Ganzes zu enthüllen und zu berücksichtigen.
The loss of Jê nominal verbs in Panará
Authors: Bardagil Bernat 
Published: November 2022

AbstractIn Jê languages, verbs appear in a non-finite form that fulfills a double function: licensing marked TAME semantics in main clauses, and licensing embedded clauses. However, the Panará language lost its non-finite verbal form. This paper examines Panará verbs from both a synchronic and diachronic angle, and in a broader comparative approach with regards to the morphosyntactic behaviour of verbs in the other Jê languages. The main claim is that the non-finite forms prevalent in the Jê family underwent a reanalysis in Panará, resulting in fully finite clauses in all environments.
Regulation of the photovoltaic performance of TiO2@MAPbI3 core–shell nanowire arrays

Abstract
To further the exploration of perovskite nanowires, TiO2@CH3NH3PbI3 (TiO2@MAPbI3) core–shell nanowire arrays were successfully prepared via immersion and spin-coating methods. Because the shell thickness has a significant influence on the carrier transport capacity of nanowire arrays, different shell thicknesses were obtained by changing the precursor concentration. Subsequently, the relationship between the precursor concentration and shell thicknesses and the resulting properties of the nanowire arrays were investigated. The X-ray diffraction results showed that the prepared nanowire arrays consisted of only MAPbI3, TiO2, and fluorine-doped tin oxide phases, with no impurities. From the scanning electron microscopy and energy dispersive X-ray spectroscopy results, the MAPbI3 shell material was successfully coated onto the core layer of the TiO2 nanowire arrays. In addition, the average size of the core–shell nanowire arrays and the shell thickness were obtained using scanning electron microscopy and related software analyses. The results showed that the shell thickness was the largest (40 nm) when the precursor concentration was the lowest (0.025 mol L−1). Ultraviolet–visible spectroscopy showed that when the precursor concentration was 0.025 mol L−1 and the shell thickness was the largest, the nanowire array exhibited the highest absorbance and the smallest band gap, which is conducive to generating more carriers and improving its photovoltaic performance; the J–V curve showed the highest photoelectric conversion efficiency at this concentration and shell thickness. Therefore, it can be inferred that the shell thickness may affect the optical and photovoltaic properties. The relationship between the precursor concentration and thickness as well as the influence of this relationship on the properties of core–shell nanowire arrays should be further explored, to establish a foundation for the use of perovskite nanowires in the photovoltaic field.
A study of melting temperatures in bismuth and antimony
Authors: Kuchhal Piyush , Dass Narsingh 
Published: November 2022

Abstract
We studied the melting temperatures of bismuth and antimony as a function of pressure in this paper because, unlike other solids, melting temperatures are found to fall with increasing pressure. A phenomenological model is proposed to represent the melting temperature as a function of pressure in both solids using Lindemann’s criterion. The computed results are found to be very close to the experimental data. The average absolute percentage relative deviation (AARD%) in bismuth is 0.012, 0.038 in antimony (set-1) and 0.128 in antimony (set-2). Furthermore, the minimum condition is obtained, which gives the pressure at the minimum melting temperature.
Performance analysis of 2λ × 160 Gbps optical single sideband (OSSB) generation in polarization division multiplexed (PDM) QPSK based satellite wireless optical systems (SWOS)
Authors: Garg Raveena , Kaur Gurpreet , Kumar Naresh 
Published: November 2022

Abstract
Capacity enhancement in satellite wireless optical systems (SWOS) systems is an ultimate task to accomplish due to ever-increasing internet services and it can be achieved by incorporating polarization division multiplexed (PDM) quadrature phase shift keying (PDM-QPSK). Herein, 2λ × 160 Gbps intersatellite optical wireless communication (IsOWC) system is proposed using PDM-QPSK. Spectral efficiency is prime requirement to enhance the performance of system and therefore, a suppression of optical single sideband (OSSB) in PDM-QPSK carrier spectrum is performed by employing fiber Bragg grating with 0.99 reflectivity. Proposed system is investigated in terms of log BER and error vector magnitude percentage (EVMP) at varied SWOS distances. Further, effects of the digital signal processing (DSP) in the receiver are analyzed by considering and neglecting the module. Results revealed that suppression of sidebands and employment of DSP enhance the system performance and competent to cover 52,000 km SWOS distance.
Caesar’s First Consulship and Rome’s Democratic Decay
Authors: Rafferty David 
Published: November 2022

SummaryThis article argues for the usefulness of recent scholarship on democratic decay (especially in the disciplines of political science and constitutional law) for explaining the breakdown of Rome’sres publicaduring the 50s BCE, with a particular focus on Steven Levitsky and Daniel Ziblatt’s “How Democracies Die” (2018). Using “democracy” in the neo-republican sense of government free from domination, Levitsky and Ziblatt show how the actions and reactions of political actors can damage a political system without any intention to overthrow it. This article combines their insights with concepts from Christian Meier’s “Res Publica Amissa”(2nd edition 1980) to analyse Caesar’s first consulship in 59 BCE. After explaining how the theory can responsibly be applied, it closely examines the major events of the year, especially the contest over the agrarian law. Caesar’s actions throughout the year demonstrate Levitsky and Ziblatt’s warning signs for a potential authoritarian, as do those of the opposition. This analysis helps us more clearly understand just how the events of “the consulship of Julius and Caesar” (Suet. Iul. 20.2) contributed to Rome’s democratic decay in succeeding years. The article connects to much recent work on late-republican political institutions. It also helps make this dramatic period of Roman history comprehensible to political scientists by analysing it in their own theoretical terms.
Not Only “invincible in arms, a glorious warrior” (Plut. Pyrrh. 11.8). Pyrrhus and the Administration of the Epirote Kingdom
Authors: Domínguez Adolfo J. 
Published: November 2022

SummaryIn relation to King Pyrrhus of Epirus, a great number of studies have analysed his different military campaigns, but very few have focused on the political and economic aspects of his reign. Based on a series of references taken from literary accounts, we seek to demonstrate how the internal organisation of the Kingdom of Epirus under Pyrrhus was similar to that of other contemporaneous Hellenistic kingdoms, replete with a Court consisting of a large number of the king’s friends and companions. Using certain archaeological evidence, especially funerary remains, we seek to reflect the existence of this Epirote élite in material terms. The literary tradition bears witness to an interest in agriculture and livestock farming during Pyrrhus’ period, although the accounts handed down to us provide little detail. Once again, archaeology enables us to provide corroborating evidence. In this respect, we focus on the existence of a series of fortified rural residences distributed in irregular manner throughout Epirote territory, which are interpreted as being those of the members of this aristocratic élite, who used these fortified enclosures as centres of exploitation for their lands and as symbols of their power and prestige. As comparative points of reference that enable us to understand these processes, we provide various examples from neighbouring Macedonia, a kingdom with which Epirus maintained close links, especially as of the mid-fourth century B.C., which appears to be the period in which many of these new developments also began to emerge in Epirus, reaching their culmination during the reign of Pyrrhus.
The Fame of Trajan: A Late Antique Invention

Published: November 2022

SummaryTrajan’s status as a model emperor is perhaps most famously expressed in Eutropius’ catchphrase “More fortunate than Augustus, better than Trajan” (Eutr. Brev. 8.5.3). Modern scholarship has similarly stressed Trajan’s exemplary status, assuming that Trajan’s virtues were already a point of departure by which to measure second- and third-century emperors. This article challenges that notion; it argues that Trajan’s status as a model emperor was a late-antique literary construct. Trajan only entered the repertoire of exemplary emperors during the course of the fourth century to become the model emperor in the very late-fourth- and early-fifth century. This development depended on the historical context and ideological demands, as well as on the availability of the then-existing material discussing and depicting the historical Trajan.
Umgang mit Schuld in der humanistischen Seelsorge
Authors: Lauke Anke 
Published: November 2022

Zusammenfassung
Bei der Bewältigung von Schulderfahrungen kann gerade für nicht-religiöse und konfessionslose Menschen eine humanistisch-seelsorgliche Begleitung hilfreich sein. Humanistische Seelsorge ist eine professionelle Begleitung im Umgang mit Sinn- und ethischen Fragen auf Basis humanistischer Weltanschauung.
Dieser Artikel unterscheidet zwischen drei Aspekten von Schuld: erstens reale Schuld, bei der eine andere Person geschädigt wurde. Humanistische Seelsorge kann hierauf antworten durch eine Erweiterung des Raums für die Exploration moralischer Orientierung von Klient/-innen angesichts möglicher paradigmatischer Diskurse sowie durch Berücksichtigung der Fürsorge für die Klient/-in als auch jener für Dritte. Der zweite Aspekt, intrapsychische Schuldgefühle, wird als Ausdruck eines Verlangens nach einer authentischeren moralischen Orientierung gesehen und fordert dazu heraus, dieses aufzuspüren. Drittens erfordert existenzielle Schuld, die ein Bedauern über nicht gelebte Möglichkeiten des Lebens ist, die Fähigkeit, Klient/-innen zu unterstützen, zu den eigenen Potentialen zu stehen bzw. am Lebensende erlebte Tragik liebevoll anzunehmen.
Humanistische Seelsorge eröffnet angesichts aller Erscheinungsweisen von Schuld Raum, um moralische Orientierung im Zusammenhang des gesamten Lebens zu untersuchen. Vor allem liegt die Stärke humanistischer Seelsorge darin, sich mit Klient/-innen in den Morast existenzieller und ethischer Fragen zu begeben. Deshalb ist sie auch dann von Bedeutung, wenn kein gerader oder gar kein Weg durch Schulderfahrungen hindurch gefunden wird.
Conserved Population Dynamics in the Cerebro-Cerebellar System between Waking and Sleep
Authors: Xu Wei , De Carvalho Felipe , Jackson Andrew 
Published: November 2022

Despite the importance of the cerebellum for motor learning, and the recognized role of sleep in motor memory consolidation, surprisingly little is known about neural activity in the sleeping cerebro-cerebellar system. Here, we used wireless recording from primary motor cortex (M1) and the cerebellum in three female monkeys to examine the relationship between patterns of single-unit spiking activity observed during waking behavior and in natural sleep. Across the population of recorded units, we observed similarities in the timing of firing relative to local field potential features associated with both movements during waking and up state during sleep. We also observed a consistent pattern of asymmetry in pairwise cross-correlograms, indicative of preserved sequential firing in both wake and sleep at low frequencies. Despite the overall similarity in population dynamics between wake and sleep, there was a global change in the timing of cerebellar activity relative to motor cortex, from contemporaneous in the awake state to motor cortex preceding the cerebellum in sleep. We speculate that similar population dynamics in waking and sleep may imply that cerebellar internal models are activated in both states, despite the absence of movement when asleep. Moreover, spindle frequency coherence between the cerebellum and motor cortex may provide a mechanism for cerebellar computations to influence sleep-dependent learning processes in the motor cortex.SIGNIFICANCE STATEMENTIt is well known that sleep can lead to improved motor performance. One possibility is that off-line learning results from neural activity during sleep in brain areas responsible for the control of movement. In this study we show for the first time that neuronal patterns in the cerebro-cerebellar system are conserved during both movements and sleep up-states, albeit with a shift in the relative timing between areas. Additionally, we show the presence of simultaneous M1-cerebellar spike coherence at spindle frequencies associated with up-state replay and postulate that this is a mechanism whereby a cerebellar internal model can shape plasticity in neocortical circuits during sleep.
