Atrición lingüística, ¿término correcto para este “nuevo” fenómeno lingüístico?
Authors: Dorado Escribano Guadalupe 
Published: October 2020

ResumenLa lingüística abarca una amplia gama de fenómenos que evolucionan a la misma velocidad que las lenguas lo hacen. Algunos fenómenos lingüísticos como la atrición han sido confundidos con otros fenómenos y han recibido nombres distintos en el transcurso de la historia debido al contacto entre varias lenguas. Por ese motivo, un estudio sobre dicho fenómeno se estima oportuno. Esto engloba la elección de la palabraatricióncomo traducción deattrition, su definición, las circunstancias que deben producirse para que surja, los tipos de atrición que pueden darse y una comparación de la atrición lingüística con otros fenómenos lingüísticos. Esta exploración concluye con el hecho de que la atrición es el término apropiado, ya que delimita este fenómeno lingüístico que, aunque no es un fenómeno nuevo, sí es cada vez más actual debido a las migraciones y a la globalización.
Priorität oder Randerscheinung? Eine Analyse zur Relevanz der Digitalisierung in Sportvereinen
Authors: Ehnold Peter , Steinbach Dirk , Schlesinger Torsten 
Published: October 2020

Zusammenfassung
Trotz einer bereits vor der COVID-Krise erkennbar großen gesellschaftlichen Bedeutung und möglicher Potenziale der Digitalisierung für den organisierten Sport, liegen bislang nur wenige aussagekräftige Befunde darüber vor, welchen Stellenwert Sportvereine der Digitalisierungsthematik innerhalb der Vereinsarbeit beimessen. Vor diesem Hintergrund geht der Beitrag folgenden Fragen nach: (i) Welche Priorität messen Sportvereine dem Thema Digitalisierung bei? (ii) Welche vereinsspezifischen Faktoren beeinflussen die jeweilige Priorisierung des Themas Digitalisierung? Die Priorisierung der Digitalisierung wird dabei in Abhängigkeit von Vereinszielen, einstellungs- und organisationskulturbezogenen Faktoren sowie den unterschiedlichen organisationalen Kapazitäten der Sportvereine modelliert. Für die Analyse konnte eine Stichprobe von n = 787 Sportvereinen generiert werden. Die Befunde zeigen, dass Digitalisierung für Vereine vor der COVID-Krise zwar ein wichtiges Thema, aber kein Thema von herausgehobener Priorität innerhalb der Vereinsarbeit darstellt. Die Ergebnisse des logistischen Regressionsmodells deuten darauf hin, dass die Unterschiede in der Priorisierung vor allem auf Differenzen in der Organisationskultur und der Organisationskapazität zurückzuführen sind.
Evaluation of the acoustic emission caused by the chip segmentation frequency during machining of titanium alloy

Published: October 2020

Abstract
This work investigates the relationship between acoustic emission and chip segmentation frequency of Ti-6Al-4V at the external longitudinal turning process. Therefore, several sensors like structure borne sensors, microphones and a force dynamometer have been installed in a vertical turning machine. To induce a change of the segmentation frequency, several experiments with different feed rates have been carried out. From each experiment the acoustic emissions have been recorded and the generated chips have been analyzed. Since the chips get stretched or compressed during the chip formation the change in the length is calculated to get an estimation of the segmentation frequency. The comparison of the spectral analysis of the acoustic emission signals and the chip analysis has shown that both methods show the same tendency. The segmentation frequency decreases with increasing feed.

Abstract

Objective
Data on bacterial diversity and microbiota alterations in acromegaly are currently lacking. The effects of somatostatin receptor analogs on gut microbiota remain unknown. The objective of this study was to determine microbiota alterations in patients with acromegaly and to assess the effects of somatostatin receptor analogs on gut microbiota.

Methods
The study was designed as a cross-sectional case-control research and three cohorts, comprising individuals with acromegaly without medical therapy (n=5), acromegaly receiving octreotide acetate (OCT) (n=8) and healthy controls (n=5), were evaluated.

Results
No statistically-supported changes in Bacteroidetes, Firmicutes, Proteobacteria and Actinobacteria abundance were observed. Bacteroidaceae, Odoribacteraceae, Porphyromonadaceae, Prevotellaceae and Alistipes families of Bacteroidetes and Bifidobacterium genus of the Actinobacteria phyla were detected, without overt differences. Variations in Clostridia, Erysipelotrichaceae and Veillonellaceae were not significant, while Lactobacillales were increased in individuals receiving OCT. Moreover, Akkermansia mucinophila was present in patients under OCT treatment.

Conclusion
Our preliminary results suggest that the bacterial community profile under OCT treatment may facilitate a colonic microenvironment for improved glucose metabolism. Alterations in the gut microbiota may be a factor affecting diabetes development during somatostatin analog treatment in acromegalic patients.
General location across languages: On the division of labour between functional and lexical items in spatial categories
Authors: Ursini Francesco-Alessio 
Published: October 2020

AbstractIn many languages, it is possible to describe the location of any entity with respect to a landmark object without specifying the exact place that the locatum occupies (e.g. Englishatinat home). Such vocabulary items usually contrast with items that belong to the same categories but have more restricted senses (e.g.on top ofinon top of the shelf). Thus, the degree of “abstractness” that such spatial case markers can convey usually depends on the organization of the lexicon and grammar of spatial terms in each language. The goal of this paper is to explore these properties across a small sample of languages and offer an account of this variation that is connected to previous theories of spatial case markers (e.g. adpositions). Our key proposal is that the morpho-syntactic structure of spatial case markers and their phrases can license a clear division of labour between functional and lexical spatial senses. However, intermediate solutions blurring categories and semantic boundaries are shown to be possible. We formalize this proposal via a fragment of Lexical Syntax, and show that degrees of distinction between ‘functional’ and ‘lexical’ sense types and categories can be modelled via a unified account.
Dynamic response analysis of fluid-saturated porous rectangular plates
Authors: Lixian Wang 
Published: October 2020

Abstract
Based on Biot’s model for saturated porous media, the governing equation of fluid-saturated porous rectangular plates is presented, in which the compressibility of solid particles and fluid and the viscosity of pore fluid is taken into account. A series solution is given for simply-supported fluid-saturated porous plates. The accuracy of the solution is validated by degenerating the fluid-saturated porous rectangular plates into single-phase solid rectangular plates. As a numerical example, the free vibration characteristic and the dynamic response under harmonic loads are analysed. The influence of surface infiltration conditions, porosity, pore fluid permeability coefficient and loading frequency on the free vibration frequency is discussed.

Abstract
The sodium-rich sulfido and selenido metallates Na12MnIn2
Q
10 (Q = S/Se) were synthesized in pure phase from melts composed of stoichiometric quantities of the manganese monochalcogenides MnQ, elemental indium and the chalcogens together with either Na2S (Q = S) or elemental sodium (Q = Se) as starting material. The samples were heated up to maximum temperatures of 1000/900 °C under an argon atmosphere; crystallization was achieved by slow cooling rates of 10 K h−1. The two isotypic compounds (monoclinic, space group P21/m, a = 678.26(2)/698.85(10), b = 2202.77(7)/2298.7(3), c = 766.39(3)/800.59(13) pm, β = 90.232(2)/90.147(5)°, Z = 2, R1 = 0.0516/0.0575) crystallize in a new structure type. According to the division of the formula as Na12[InQ
4][MnInQ
6] the salts contain ortho indate anions [InIII
Q
4]5− besides hetero-bimetallic dimers [MnIIInIII
Q
6]7−, which consist of two edge-sharing [MQ
4] tetrahedra. The seven crystallographically different sodium cations exhibit an either tetrahedral or octahedral coordination by the chalcogen atoms. Thus, the overall structure of the salt is best described by a hexagonal close packing of the sulfide/selenide anions, in which the octahedral voids of every second interlayer section are fully occupied by the (overall 5/f.u.) Na
+
positions with CN = 6. In the other half of the interlayer sheets, all tetrahedral voids (overall 10/f.u.) are occupied by the seven CN = 4 Na
+
cations, one In3+ of the ortho anion and the two Mn2+/In3+ cations (which statistically occupy one crystallographic site). This structure relation is also verified by a Bärnighausen group-subgroup tree connecting the h.c.p. (Mg type) aristotype (with its tetrahedral and octahedral voids) by an overall index of 60 with the structure of the two title compounds.

Abstract
The solution behavior of beryllium halides and triflate in acetonitrile was studied by NMR, IR and Raman spectroscopy. Thereby mononuclear units [(MeCN)2BeX
2] (X = Cl, Br, I, OTf) were identified as dominant species in these solutions. The solid state structure of [(MeCN)2Be(OTf)2] has been determined by X-ray diffraction. If only one equivalent of MeCN is used the dinuclear compounds [(MeCN)BeX
2]2 (X = Cl, Br, I) are formed. Partial halide and triflate dissociation into the monomeric complexes as well as the formation of hetero-halide complexes [(MeCN)2BeClBr], [(MeCN)2BeClI] and [(MeCN)2BeBrI] was observed.

Published: October 2020

Abstract
Garlic oil in water nanoemulsion was resulted through subcritical water method (temperature of 120 °C and pressure of 1.5 bar, for 2 h), using aponin, as emulsifier. Based on the prepared garlic oil nanoemulsion, astaxanthin–garlic oil nanoemulsions were prepared using spontaneous microemulsification technique. Response surface methodology was employed to evaluate the effects of independent variables namely, amount of garlic oil nanoemulsion (1–9 mL) and amount of provided astaxanthin powder (1–9 g) on particle size and polydispersity index (PDI) of the resulted nanoemulsions. Results of optimization indicated that well dispersed and spherical nanodroplets were formed in the nanoemulsions with minimum particle size (76 nm) and polydispersity index (PDI, 0.358) and maximum zeta potential value (−8.01 mV), using garlic oil nanoemulsion amount of 8.27 mL and 4.15 g of astaxanthin powder. Strong antioxidant activity (>100%) of the prepared astaxanthin–garlic oil nanoemulsion, using obtained optimum amounts of the components, could be related to the highest antioxidant activity of the colloidal astaxanthin (>100%) as compared to that of the garlic oil nanoemulsion (16.4%). However, higher bactericidal activity of the resulted nanoemulsion against Escherichia coli and Staphylococcus aureus, were related to the main sulfur bioactive components of the garlic oil in which their main functional groups were detected by Fourier transform-infrared spectroscopy.
Thermodynamics and acoustic effects of quercetin on micellization and interaction behaviour of CTAB in different hydroethanol solvent systems
Authors: Abbot Vikrant , Sharma Poonam 
Published: October 2020

Abstract
Flavonoids amongst the class of secondary metabolites possess numerous health benefits, are known for its use in pharmaceutical industry. Quercetin, a flavonoid has more prominent medical advantages however its utilization is constrained because of various instability and insolubility issues and therefore, taken into consideration for studying its physico-chemical properties. In view of that, the thermodynamic and thermoacoustic properties of quercetin were examined in presence of cationic surfactant cetyltrimethylammonium bromide (CTAB) at different hydroethanolic concentrations and temperatures. The conductivity studies were used to calculate change in enthalpy (∆H

o

m
), change in entropy (∆S

) and change in Gibbs free Energy (∆G

m
) of micellization. The interactions between quercetin and CTAB were found to be endothermic, entropically controlled and spontaneous. Further, ultrasonic sound velocity and density studies were carried out and utilized for the calculation of thermoacoustic parameters i.e. apparent molar volume and apparent molar compressibility. Thermoacoustic properties revealed that at higher surfactant concentration, hydrophobic interactions are dominant. The results suggested that the flavonoid-surfactant interactions in hydroethanolic solutions is more favourable as compared with aqueous solution. Overall, the data is favourable for the framework to be used for detailing advancement, drug development, drug industry, pharmaceutical industry, medical administration and formulation development studies.
Geochemical Characteristics and Genesis of Deep Marine Carbonate Natural Gas in China
Authors: Li J. , Li J. , Shi J. , Li Z. , Xie Z. , Qi X. 
Published: October 2020

Abstract
—Deep and ultradeep oil and gas have been the prominent direction of international exploration in recent years. The deep oil and gas resources are predominantly distributed in the three domains of carbonate, clastic, and igneous rocks. The carbonate rock reservoirs contain about 40% of global oil and gas reserves owing to their superior reservoir properties. In recent years, a number of large oil and gas fields have been discovered in the deep marine carbonate rocks in China, especially in the Sichuan and Tarim Basins, thus showing a vast oil and gas exploration potential in these rocks. In this paper, the genesis and source of deep natural gas in the Tarim and Sichuan Basins were systematically studied. The results show that the natural gas in the deep marine carbonate rock reservoirs is generated not only from the later deep-source rocks. Also, the substantial cracking of crude oil and pyrobitumen in the reservoir under conditions of great burial depth and high geotemperature can provide abundant natural gas sources for the deep reservoir. So, the contribution of gas from oil cracking should be considered in evaluation of deep natural gas resources.
Inductively Induced Polarization and Its Overall Assessment Using a Normalized Transient Response
Authors: Kozhevnikov N.O. , Antonov E.Yu. 
Published: October 2020

Abstract
—The paper considers the basic regularities of inductively induced polarization (IIP) manifestation in the transient electromagnetic method. When calculating inductive transient responses of a polarizable ground, we assumed that the electrical conductivity of geologic materials is described by the Cole-Cole model. To present and analyze the results of computer-based simulation of the IIP phenomenon, we used a normalized transient response. It is defined as the ratio of the transient electromotive force (EMF) response of a polarizable ground to the EMF response of a ground that differs from the polarizable one only in that it has zero chargeability. The coordinates of the minimum of the normalized transient response are useful for an overall assessment of IIP manifestation. We show, by the example of a homogeneous polarizable half-space, how the inductive transient response is affected by the Cole-Cole model parameters and the size of transmitter and receiver loops. For a two-layer ground, IIP manifestation depends also on whether the base or upper layer is polarizable, as well as on the layer thickness. Inductively induced polarization is most pronounced when a conductive polarizable layer overlies a resistive nonpolarizable base. In this case, at a certain thickness of the layer, the IIP effect far exceeds that observed in the presence of a thick polarizable layer and even of a homogeneous polarizable half-space.
Gravitational Collapse of Anteclises and Its Probable Impact on the Neotectonics of Platforms and Passive Continental Margins (by the Example of the East European Platform)
Authors: Kopp M.L. 
Published: October 2020

Abstract
—Structural and geological research has shown that the extension of the Russian Plate caused a neotectonic transition of the deformed material from the Voronezh and Volga–Kama anteclises to neighboring syneclises, primarily the deepest Peri-Caspian syneclise. The resulting geologic structures and landforms morphologically resembled landslides, but their large (up to many hundreds of kilometers) lateral sizes excluded the influence of exogenous processes and made it necessary to treat this event as a gravitational collapse involving a significant crustal mass. This phenomenon was previously considered for orogens only, but the conditions for its appearance here existed too: In the late Cenozoic, the East European Platform experienced a collisional pressure from the southern boundary of the Eurasian Plate, which led to a gravitationally unstable uplift. The collapse was best manifested in the zones of junction of anteclises and syneclises, where lenses of the thickened continental crust are thinned beneath anteclises. This fact, along with the published modeling data, gave grounds to state that the platform collapse was favored by the lenticular crustal structure: The light crustal lenses forming anteclises floated up under compression and diverged under subsequent decompression. Gravitational extension and subsidence in the anteclise apexes was compensated by compression near the syneclises, where folded dislocations and neotectonic ramparts formed. It has been established that a gravitational collapse results in a specific paragenesis of platform structures and morphostructures, which can help to identify its manifestations in other places and to estimate the relationship between the relief formation and tectonics. In general, the data obtained suggest a relationship between the recent activity of passive continental margins and the gravitational collapse of the largest lenses of the continental crust.
Atom canonicity and first order definability in classes of algebras of relations
Authors: Ahmed Tarek Sayed 
Published: October 2020

AbstractFix 2 < n < ω and let CAn denote the class of cyindric algebras of dimension n. Roughly CAn is the algebraic counterpart of the proof theory of first order logic restricted to the first n variables which we denote by Ln. The variety RCAn of representable CAns reflects algebraically the semantics of Ln. Members of RCAn are concrete algebras consisting of genuine n-ary relations, with set theoretic operations induced by the nature of relations, such as projections referred to as cylindrifications. Although CAn has a finite equational axiomatization, RCAn is not finitely axiomatizable, and it generally exhibits wild, often unpredictable and unruly behavior. This makes the theory of CAn substantially richer than that of Boolean algebras, just as much as Lω,ω is richer than propositional logic. We show using a so-called blow up and blur construction that several varieties (in fact infinitely many) containing and including the variety RCAn are not atom-canonical. A variety V of Boolean algebras with operators is atom canonical, if whenever 𝔄 is atomic, then its Dedekind-MacNeille completion, sometimes referred to as its minimal completion, is also in V. From our hitherto obtained algebraic results we show, employing the powerful machinery of algebraic logic, that the celebrated Henkin-Orey omitting types theorem, which is one of the classical first (historically) cornerstones of model theory of Lω,ω, fails dramatically for Ln even if we allow certain generalized models that are only locallly clasfsical. It is also shown that any class K such that , where CRCAn is the class of completely representable CAns, and Sc denotes the operation of forming dense (complete) subalgebras, is not elementary. Finally, we show that any class K such that is not elementary, where Sd denotes the operation of forming dense subalgebra.

On power integral bases for certain pure number fields defined by x24 – m

AbstractLet K = ℚ(α) be a number field generated by a complex root α of a monic irreducible polynomial f(x) = x24 – m, with m ≠ 1 is a square free rational integer. In this paper, we prove that if m ≡ 2 or 3 (mod 4) and m ≢∓1 (mod 9), then the number field K is monogenic. If m ≡ 1 (mod 4) or m ≡ 1 (mod 9), then the number field K is not monogenic.
China at the crossroads
Authors: Csaba László 
Published: October 2020

AbstractThis essay joins in the international controversy about the nature and sustainability of the economic system in China. While official ideology continues to stick to the concept of ‘socialist market economy,’ albeit with changing contents, international observers are split. One group considers China as a de facto market economy, which is in line with the top-down tradition of ruling in the region. Others consider it as a sui generis system. And a third line takes it as yet another case of hybrid regime which proliferated globally in the new millennium. I try to create a link between these readings and the empirics of Chinese growth. This may help interpret the slowdown, exacerbated by the COVID-19 epidemics on Chinese output.
