NAIR, S. S., BACHAN, K. H. A. & EBIN, P. J. 2021. Diversity and phenetic study on syconium of Ficus L. (Moraceae) from Kerala, India revealing natural classification along with an identification key. Reinwardtia 20(1): 27–36. — Ficus L. commonly called ‘figs’ is one of the most complex genera among the angiosperms with its specialised inflorescence called syconium that looks like a fruit. Syconium of 33 species of Ficus reported from Kerala were observed here to develop a novel key, solely based on syconium morphology. Numerical taxonomic methodology for syconium morphological characters were standardised, considering 22 characters with 104 character states and analysed using similarity clustering. The floral features of the genus are very much complex and all the existing keys for the species identification relays on both vegetative as well as floral features. Hence, the present key will be practical in use when syconium is the only available part. The numerical analysis of the syconium features well clustered and separated the trees with cauliflorous inflorescence, hemi epiphytic -epiphytic life forms and independent trees similar to the natural classification of the figs as “Atthi, Itthi and Aal”, indicating that phenetic analysis using the syconium characters alone provided a grouping similar to the natural grouping based on the habit. Preliminary phylogenetic analysis of figs also provided a similar clustering. This gives an insight into the fact that the separation of figs into these natural groups is reflecting phylogenetic trait. Detailed studies including more morphological traits and molecular analysis could establish the phylogenetic relation of figs in relation to the evolutionary history of climate and vegetation.

Published: July 2021

Indonesia territorial waters are very vulnerable to the impacts of climate change. Research about the variations of sea surface temperature and chlorophyll-a concentration in the southern waters of Java has been undertaken by several researchers. However, the research is still in the scope of regional scale south of Java. This research was conducted to determine the impact of climate change on sea surface temperature and chlorophyll-a concentration in Sukabumi waters. The data used consisted of IOD index anomalies, sea surface temperature and monthly chlorophyll-a concentrations from December 2002 to November 2020. Descriptive analysis was used to determine seasonal and inter-annual variability and linear regression method was used to analyze trends in changes in sea surface temperature (SST) and chlorophyll-a concentration. The results showed that the seasonal variation was influenced by the monsoon, while the interannual variation was influenced by the Indian Ocean Dipole. Climate change causes SST and chlorophyll-a concentrations to increase. In the 2003-2020 time period, SPL increased by 0.08 °C and an increase in chlorophyll-a concentration by 0.03 mg/ m3. ABSTRAKPerairan selatan Sukabumi yang berhadapan langsung dengan samudera Hindia sangat rentan terhadap dampak perubahan iklim. Penelitian mengenai variasi suhu permukaan laut dan konsentrasi klorofil-a di perairan selatan Jawa sudah dilakukan oleh beberapa peneliti sebelumnya. Namun penelitian tersebut masih dalam lingkup skala regional selatan Jawa. Penelitian ini dilakukan untuk mengetahui dampak perubahan iklim terhadap suhu permukaan laut dan konsentrasi klorofil-a di Perairan selatan Sukabumi. Data-data yang digunakan terdiri dari indeks IOD, suhu permukaan laut dan konsentrasi klorofil-a bulanan periode Desember 2002 hingga November 2020. Metode yang digunakan dalam penelitian ini adalah analisis deskripsi dan regresi linier. Hasil penelitian menunjukkan bahwa variasi musiman suhu permukaan laut dan konsentrasi klorofil-a di perairan ini dipengaruhi oleh monsun, sedangkan variasi antar tahunan dipengaruhi oleh Indian Ocean Dipole. Perubahan iklim menyebabkan suhu permukaan laut dan konsentrasi klorofil-a mengalami kenaikan. Dalam periode waktu 2003-2020 suhu permukaan laut mengalami kenaikan sebesar 0,08°C dan kenaikan konsentrasi klorofil-a sebesar 0,03 mg/m3.

Authors: Schwartz Richard Evan 
Published: July 2021

Abstract
We prove an integral formula for continuous paths of rectangles inscribed in a piecewise smooth loop. We use this integral formula to prove the inequality M(γ) ≥ Δ(γ)/2 – 1, where M(γ) denotes the total multiplicity of rectangle coincidences, i.e. pairs, triples, etc. of isometric rectangles inscribed in γ, and Δ(γ) denotes the number of stable diameters of γ, i.e. critical points of the distance function on γ.
On the alethic and moral status of political storytelling
Authors: Klenner Niels , Köppe Tilmann 
Published: July 2021

AbstractThe article reconstructs the theory of political storytelling as outlined by political strategist Mark McKinnon. Stories that conform to this theory feature a suspense structure, and as such they invoke hope and fear in recipients, thereby instilling pro- or contra-attitudes. This is potentially problematic in four respects: Political storytelling (1) can be used to induce attitude-change without a rational foundation, thereby infringing on the receiver’s right to epistemic self-determination; (2) political storytelling may involve a misrepresentation of the teller’s communicative intentions, thereby disclosing the truth about them in a way that is potentially harmful to society; (3) by expressing rather than stating crucial elements of his or her “message,” the political storyteller may immunize him- or herself from critique and mask the true content of the message; (4) by attempting to influence recipients’ preferences, the political storyteller does not conform to some fundamental principle of representative democracy.
Unnatural narratives, Brexit and ideology in Ian McEwan’sThe Cockroach
Authors: Zhang Dandan 
Published: July 2021

AbstractAgainst the backdrop of sudden shifts in global political and historical climate, our century has witnessed a convergence of turns in humanities, including the nonhuman turn and the historical turn. Ian McEwan’s latest novella,The Cockroach, is a just work along this line. Through the use of unnatural narratives within realistic context, McEwan presents readers with a world that is both strange and recognisable. By examining the unnatural narrative strategies, including the deployment of nonhuman character and omniscient narrator, McEwan expresses concerns for the future of humanity and fear for social and cultural parochialism, populism and anti-cosmopolitanism.
The Legal Characterization of Crypto-Exchange Platforms
Authors: Minto Andrea 
Published: July 2021

Abstract
In a thriving crypto-assets market, crypto exchange platforms play a pivotal role. Indeed, such trading systems are instrumental to the matching of demand and supply (trading) as well as the transfer of tokens (settlement and post-trading). Yet, there is currently no bespoke regulatory framework applicable to crypto exchange, raising pressing questions on whether and how those platforms are regulated. This article examines the Italian regulatory framework applicable to crypto-exchange platforms. It shows that the present regulatory engagement with crypto exchanges relates to the qualification of the crypto assets traded. Depending on such qualification, different financial regimes could be triggered.
Freie mündliche Interaktion – Eine kriteriengeleitete Lehrwerkanalyse von drei Grundstufenlehrwerken des Niveaus A2: Studio d, Optimal und Schritte international
Authors: Suresh Indira 
Published: July 2021

Zusammenfassung
Mit der kriteriengeleiteten Lehrwerkanalyse betritt dieser Beitrag bekanntes Terrain: Kriterien für die Beurteilung von Lehrwerken zu formulieren hat im Fach Tradition. Die Analyse von drei A2-Lehrwerken zeigt, dass Aufgabenformate zur freien mündlichen Interaktion oft nicht angemessen vorbereitet werden. Bei Lernenden sind Überforderung und daraus resultierende Sprechhemmungen zu beobachten, denn viele Aufgabenformate sind nur unzureichend in kleinschrittige Sequenzen unterteilt. Die Lehrkraft muss die Schwachstellen der Lehrwerke daher durch Ergänzungsübungen kompensieren.

Published: July 2021

Abstract
In this manuscript, a purely data-driven statistical regularization method is proposed for extracting the information from big data with randomly distributed noise.
Since the variance of the noise may be large, the method can be regarded as a general data preprocessing method in ill-posed problems, which is able to overcome the difficulty that the traditional regularization method is unable to solve, and has superior advantage in computing efficiency.
The unique solvability of the method is proved, and a number of conditions are given to characterize the solution.
The regularization parameter strategy is discussed, and the rigorous upper bound estimation of the confidence interval of the error in the

Born-Digital Logistics: Impacts of 3D Recording on Archaeological Workflow, Training, and Interpretation
Authors: Scott Catherine B. , Roosevelt Christopher H. , Nobles Gary R. , Luke Christina 
Published: July 2021

Abstract
Digital technologies have been at the heart of fieldwork at the Kaymakçı Archaeological Project (KAP) since its beginning in 2014. All data on this excavation are born-digital, from textual, photographic, and videographic descriptions of contexts and objects in a database and excavation journals to 2D plans and profiles as well as 3D volumetric recording of contexts. The integration of structure from motion (SfM) modeling and its various products has had an especially strong impact on how project participants interact with the archaeological record during and after excavation. While this technology opens up many new possibilities for data recording, analysis, and presentation, it can also present challenges when the requirements of the recording system come into conflict with an archaeologist’s training and experience. Here, we consider the benefits and costs of KAP’s volumetric recording system. We explore the ways that recording protocols for image-based modeling change how archaeologists see and manage excavation areas and how the products of this recording system are revolutionizing our interaction with the (digital) archaeological record. We also share some preliminary plans for how we intend to expand this work in the future.
Are persistent aircraft trails a threat to the environment and health?
Authors: Deruelle Fabien 
Published: July 2021

Abstract
According to most scientific studies, media and governments, the white trails that can be seen behind aircraft in flight, corresponding to condensation mixed with engine particulate emissions, only persist under specific atmospheric conditions. They are called condensation trails, and cirrus contrails when they remain for hours to reach several kilometers wide. The fact that they have gradually filled the skies over the last twenty years would be due to the increase in air traffic. However, other official documents link these persistent trails to a weather modification technology called solar geoengineering by stratospheric aerosol injection (SAI). These sprays would be mainly composed of metallic particles (Al, Ba, Sr, Fe, nanoparticles) and sulfur, which would considerably increase air, soil and water pollution. Many of the current environmental and health problems are consistent with those described in the literature on solar geoengineering by SAI if this method was employed. For example, metal particles used are well known environmental contaminants, ozone layer depletion, cardiorespiratory diseases, neurodegenerative diseases, sunburn. The observations (whiter skies, less solar power) also correspond to the same risks as those described in the solar geoengineering works. Patents show that this weather modification technology has been known and mastered for a long time. In addition, some scientific papers as well as policy documents suggest that solar geoengineering by SAI has been used for many years. The amount of official information presented in this review is intended to open new ways of investigation, free of conflicts of interest, about the growing global pollution of persistent aircraft trails and their possible links with solar geoengineering by SAI.
Newfangled progressions in the charge transport layers impacting the stability and efficiency of perovskite solar cells
Authors: Jaffri Shaan Bibi , Ahmad Khuram Shahzad 
Published: July 2021

Abstract
Organic-inorganic lead halide perovskite solar cells have rapidly emerged as a newfangled material for solar energy harnessing. Perovskite solar cells have succeeded in gaining a power conversion efficiency of 25% in the last year, further enhancement in the efficiency is anticipated due to advanced engineering of the different components making up the complete cell architecture with enhanced performance, stability and efficiency. Significant components of perovskite solar cell configurational architecture are the electron transport layer, active perovskite absorber layer, hole transport layer and counter electrode. Considering the profound role of transport layers in charge mobility, current review has particularly elucidated the advancements in the charge transport layers. The time duration of the review is from 2010 to 2021. However, the special focus has been laid on the recent articles. The influence of different organic and inorganic materials used for development of transport layers influencing the cell performance have been summarized. Materials used for transport layers have been modified by utilization of myriad of engineered substances through doping and surface functionalization strategies but every method have been marked by posing serious challenges towards the stability and efficiency of the cell and thus, hindering its commercialization. The review also provides an elucidation of the mechanical challenges and abatement strategies. These strategies are associated with the charge transport layers for enhancement of cell functionality.
Nation als gefühlte Gemeinschaft
Authors: Voigt Katrin 
Published: July 2021

ZusammenfassungAusgehend von Sara Ahmeds Beobachtung, dass die Bekundung nationaler Scham ein Idealbild der Nation als gefühlte Gemeinschaft konstruiert, untersucht der Artikel die Bedeutung der Emotion Scham in einer Interviewstudie zum Thema nationale Identität mit deutschen Staatsbürger*innen im Kontext der Fußballweltmeisterstaft der Männer 2018. Dabei wird deutlich, dass das Thema nationale Scham innerhalb des Samples auf vielfältige Weise verhandelt wird und bei einigen Interviewten starke Ambivalenzen auslöst. Der Artikel arbeitet unterschiedliche Mechanismen heraus, die zur Überwindung dieser Ambivalenzen von den Interviewten angewendet werden – insbesondere das Konstrukt der gesellschaftlichen Mitte und die Inszenierung eines unpolitischen Raumes im Fußball – und untersucht kritisch deren Funktion hinsichtlich von Distinktionsgewinnen innerhalb der Nation wie auch nach außen.
Optimization of a circumferential groove in a centrifugal compressor
Authors: Oh Myong Hun , Ko Jaeik , Park Jun Young , Choi Minsuk 
Published: July 2021

Abstract
In this work, a circumferential groove on the shroud was applied to a centrifugal compressor and optimized to improve the stability of the compressor. To reduce the number of design variables before optimization, the position of the casing groove that maximizes the stall margin of the compressor was firstly selected. The width and height of the casing groove were optimized using the RSM (Response Surface Method) and the full factorial design of experiments to increase the stall margin further. It was observed that the optimized case with the casing groove can increase the stall margin by 7.0% but the adiabatic efficiency at the design condition decreases by 0.99%, in comparison to the reference case without the groove. Finally, the flow field of both cases with and without the optimized casing groove was compared to each other to analyze effects of the casing groove on the stall margin and design efficiency. The casing groove decreases the leakage flow across the impeller tip and weakens the tip leakage vortex, consequently decreasing the blockage near the shroud and improving the stall margin. However, it was found that the spillage of the flow from the casing groove increases the mixing loss near the shroud.

Published: July 2021

Abstract
In this paper, Sn-doped TiO2 nanomaterials with varying concentrations were manufactured through a simple procedure. The fabricated TiO2 and Sn loaded on TiO2 nanoparticles were studied using X-ray diffraction, scanning electron microscopy, transmission electron microscopy, energy dispersive X-rays, Fourier transform infrared spectroscopy, and resistance analyses. The benefits of dielectric constant and ac conductivity rise at high Sn loaded concentration on TiO2 nanoparticles. The enhanced electrical conductivity is seen for STO3 (3.5% Sn doped TiO2) and STO4 (5% Sn doped TiO2) specimens are apparently associated with the introduced high defect TiO2 lattice. Furthermore, the fabricated specimens’ obtained findings may be applied as possible candidates for high-energy storage devices. Moreover, proper for the manufacture of materials working at a higher frequency.
Postoperative hypoparathyroidism after completion thyroidectomy for well-differentiated thyroid cancer
Authors: Giordano Davide , Botti Cecilia , Piana Simonetta , Zini Michele , Frasoldati Andrea , Lusetti Francesca , Cavuto Silvio , Savoldi Luisa , Pernice Carmine , Ghidini Angelo 
Published: July 2021

Objective
Thyroid surgery may lead to postoperative complications. The aim of this paper was to determine whether the rate of postoperative hypoparathyroidism (HPT) is influenced by whether surgery is staged.

Design
Single-institution retrospective observational study.

Methods
The clinical records of 786 patients treated at the Otolaryngology Unit of the Azienda USL-IRCCS di Reggio Emilia between January 1990 and December 2015 were reviewed. Patients were divided into two groups according to the surgical treatment received: group TT (637 patients, 81.04%) underwent single-stage total thyroidectomy; Group cT (149 patients, 18.96%) underwent loboisthmusectomy and delayed completion total thyroidectomy. Transient and permanent HPT, assessed after 6 months of follow-up, were the primary endpoints. Risk factors of postoperative HPT were also analysed as secondary outcomes.

Results
Rates of transient HPT in group TT were higher than those observed in group cT, (P = 0.0057). Analysis of risk factors identified sex as an independent risk factor for transient HPT only for group TT (P = 0.0012) and the number of parathyroid glands remaining in situ (PGRIS) as an independent risk factor for transient and permanent HPT for group TT (P < 0.0001 and P = 0.0002, respectively).

Conclusions
This study suggests that the risk of transient postoperative HPT is lower in patients that undergo completion thyroidectomy. Further independent risk factors for postoperative HPT are female sex and PGRIS score. In light of the growing use of conservative surgery for thyroid neoplasms, these findings could help to adequately plan surgery in order to reduce endocrine complications.
La Racionalidad Ecológica de los Costos Históricos y el Conservadurismo
Authors: Braun Eduard 
Published: July 2021

Los principios que caracterizan el enfoque tradicional de ingresos y gastos en la contabilidad no pueden remontarse a un evento histórico particular, son racionales ecológicamente. Su funcionalidad es la consecuencia de la evolución cultural y no de un diseño humano específico. Ésta es la razón por la que los esfuerzos por defender el enfoque de activos y pasivos, avalado por los emisores de estándares, han encontrado dificultades sustanciales. Sólo este último enfoque se basa claramente en un modelo económico puntual a saber, la economía neoclásica.
En contraposición, se argumenta que una base sólida para explicar la racionalidad de los principios de contabilidad que evolucionaron culturalmente se puede encontrar en la economía del comportamiento. Estos principios están en línea con las conductas humanas que se han evidenciado en numerosos experimentos de campo y laboratorio. Es especialmente con respecto a la teoría prospectiva que se identifica un paralelo cercano.
Además, este análisis se combina con una visión del proceso de mercado en la economía. La contabilidad financiera según el enfoque de activos y pasivos no agrega nueva información al mercado, solo resume a nivel de la empresa la información proporcionada por este. Por el contrario, el enfoque de ingresos y gastos suministra información privada al mercado, al estilo de lo descrito por Hayek (1945). El enfoque de ingresos y gastos resulta, por tanto, compatible con la organización de la economía de mercado.
