Published: October 2021

The implementation of the Internet of Things (IoT) is mostly done through cellular networks which do not cover the whole world. In addition, the explosive growth of global Internet access demand introduces the need for integrating satellites with cellular IoT networks for coverage extension and backhaul offloading. Operating hybrid satellite-IoT (SIoT) networks, however, might incur excessive service latency and high satellite bandwidth consumption. To tackle these issues, edge caching technology has been considered in SIoT. This article reviews existing research on edge caching-based SIoT networks with illustrative performance evaluation. Various caching design criteria with a focus on two-tier cache-enabled SIoT are discussed. In addition, open research problems on edge caching in SIoT are identified as future research directions and opportunities.

Reviving Antitrust Enforcement in the Airline Industry
Authors: Edelman Jonathan
Published: October 2021

The Department of Transportation (DOT) has broad but oft overlooked power to address antitrust issues among airlines through section 411 of the Federal Aviation Act. However, the DOT’s unwillingness to enforce antitrust more aggressively may be translating into higher fares and fees for airline travelers.

More aggressive antitrust enforcement is urgently needed. Recent research has revealed a widespread practice of common ownership in the airline industry, whereby investment firms own large portions of rival airline companies. Although this practice leads to higher prices and reduced competition, antitrust regulators, from the DOT to the Department of Justice and the Federal Trade Commission, have declined to take action. This Note argues that the DOT has the clear legal authority—and the responsibility—under section 411 to address common ownership among airlines by promulgating a rule that limits investors’ ability to own large shares of multiple airlines. DOT regulation in this area could pave the way for more muscular antitrust regulation among industry-specific agencies.
On the threshold of the Tunis School
Authors: Messaoudi Alain , Strachan (Translator) Simon
Published: October 2021

On the occasion of the inauguration of the first gallery founded by artists in Tunis, the painters Moses Levy, Pierre Boucherle, Antonio Corpora and Jules Lellouche published in 1936 a manifesto affirming their autonomy, beyond mercantile logics and national assignments. However, a national reading of their works prevailed in the press, at that time. This article proposes to put this founding event of the « École de Tunis » into context, by reinscribing it in a century-old history. This past is marked by the presence of French and Italian artists between 1840 and 1880, by the failure of a policy of asserting a French artistic model with an aborted project for a French museum around 1890, and by the affirmation of an artistic life characterised since the 1910s by its pluralism and even its eclecticism. This article thus intends to contribute, through the example of pictorial production, to the historicisation of discourses on the plurality or cultural identity of Tunisia, which are still today objects of debate.
Aortic complications in pregnancy: the less remembered chapter—a narrative review
Authors: Rajasekaran Preetha , Gandhi Praveena , Idhrees Mohammed , Velayudhan Bashi V.
Published: October 2021

Pregnancy increases the risk of common vascular events and also the rarer events like aortic dissection (AD)/aortic rupture and this is even more pronounced in patients with predisposing aortopathies. AD was found to occur in 0.0004% of all pregnancies, and it is more pronounced in patients with underlying connective tissue disorders. The normal hemodynamic changes on a weak aorta will lead to AD and/or rupture, more so with increase in the period of gestation. Hence the haemodynamic and hormonal changes during pregnancy make pregnancy itself a risk factor for AD. It is advised that women with Marfan syndrome who are planning pregnancy should go through prophylactic aortic repair if the diameter of the ascending aorta exceeds 4 cm. Pre-pregnancy counselling is very important in these patients and must include complete history taking, including family history, physical examination and advanced aortic imaging. There is a general consensus among various authors advising against surgery during pregnancy in stable patients due to increased maternal and fetal morbidity but it is justified if the condition is refractory to medical management or in life threatening stage like acute AD. Though the incidence of aortopathy in pregnancy is rare, there is a high maternal and fetal mortality associated with this condition.
Preparation of Vermiculite-based Ni-phyllosilicate for Dry Reforming of Methane
Authors: Zhu Xiaofeng , Zhao Teng , Huang Yufan , Wang Zijun
Published: October 2021

Layered porous SiO2 (V-SiO2) was designed and prepared from vermiculite by expansion-acidification method, and then used as a catalyst support to prepare Ni/V-SiO2 for dry reforming of methane. It is well known that sintering and carbon deposition of metal particles are two main problems in deactivation of nickel-based catalysts for methane dry reforming. It is reported that strong metal support interaction is a possible solution. Here, a Ni/V-SiO2-H catalyst derived from Ni-phyllosilicate was developed, and compared with the catalyst Ni/V-SiO2-IM by impregnation method. The results showed that the Ni/V-SiO2-H catalyst had high catalytic activity and stability, and the CH4 conversion reached 71.7% at 700 �C. The reason is that on the one hand, the active metal particles in the catalyst are small (8.3 nm) and relatively evenly dispersed; on the other hand, the catalyst has strong metal support interaction, which improves the anti sintering ability of the catalyst and affects the catalytic activity. It is considered that V-SiO2 as a catalyst support for the preparation of Ni-phyllosilicate may have wide application.

Published: October 2021

51CrV4 spring steel is widely used in heavy duty dump trucks ascribing to its superior mechanical properties. The fatigue life and strength of dump trucks are the main performance indicators that must be considered in the manufacturing process. Cryogenic treatment (CT) can improve the main performance of materials which has been proved by recently research. The effect of cryogenic treatment CT on the axial tensile fatigue strength of 51CrV4 spring steel was studied in this paper. The results showed that the axial tension-tension fatigue life of 51CrV4 spring steel after CT was significantly higher than conventional heat treatment (CHT) samples. The microstructure of 51CrV4 leaf spring material is mainly acicular bainite and thin strip martensite after CT. Compared with CHT, CT makes the microstructure of the material more compact. The introduction of cryogenic treatment (CT) before tempering makes the Ca element in the material aggregate, and the micro amount of Ca has the function of deoxidizing and desulphurizing and improving the morphology of sulfide, thus enhancing the fatigue life of the material.

Published: October 2021

The article analyses strengths and weaknesses of bandsaw machines. While analysing we have found the relationship between the weaknesses and the tension of a band saw. Its use as a cutting tool leads to a decrease in the lateral rigidity and stability of the cutting section on the pulling chain. This leads to fluctuations in the cutting width, a decrease in the geometric accuracy of sawn timber and an increase in the roughness of the side surfaces of a kirf. The main types of tensioning unit mechanisms, which strengthen the tension and maintain its stability during operation, are defined, and common design flaws are described. Oil-filled metal plate dampers promote space-saving and low-inertia dampers for bandsaw machines with any basic saw blade tensioning mechanisms. The influence of the device on the level of dynamic fluctuations of the tensile force caused by the artificial eccentricity of the tension pulley was studied. The efficiency was evaluated by computer oscillography of the tensile load sensor signal and subsequent computer processing of the obtained oscillograms. The effectiveness of using damper devices is confirmed by the quality of sawing, which is characterized by a lower level of roughness of the lateral surfaces of the cut while reducing the variation in thickness of a workpiece. Methods of eliminating flaws with different types of tensioning units are reviewed, and the effectiveness of using oil-filled plate dampers is evaluated. The article presents the research technique and parameters of the experimental unit as well as the conclusions on the effectiveness of damping devices.

Influence of Cardboard Pretreatment on the Determination of Starch Content by the Enzymatic Method
Authors:   Northern (Arctic) Federal University named after M.V. Lomonosov, Khadyko Igor A. , Novozhilov Evgeny V. , Chukhchin Dmitry G.
Published: October 2021

We determined the amount of starch by the enzymatic method in different samples of corrugated cardboard, including the sample produced of primary semi-finished products and corrugated cardboard made of 100 % waste paper. For starch enzymatic degradation, it is necessary to extract it from the corrugated board structure, since the processes of compression and keratinization of pulp fibers reduce the availability of starch for extraction. Enzymatic treatment requires the use of a complex amylolytic preparation for complete hydrolysis of starch to glucose. We were able to determine, respectively, 70 and 84 % of starch obtained from primary semi-finished products by mechanical methods, such as defibrillation in water and degradation in a liquid nitrogen medium, and added at the production stage of corrugated cardboard. It was shown that extraction with alkaline agents was necessary for more complete extraction of starch from corrugated cardboard. The influence of alkaline treatment on the characteristics of fibers of waste paper fractions obtained at the Sukhonsky Cardboard and Paper Mill has been analyzed. The fibers swell in alkali, resulting in an increase in fiber width and its shortening, as well as a decrease in crystallinity, which can be a positive opportunity for more complete starch extraction. Fiber swelling and crystallinity reduction are more intensive for the short fiber fraction compared to the long fiber fraction. When determining starch in corrugated cardboard using the standard method SCAN-P 91:09 SСAN-W 13:09 it was not possible to detect all the starch added at the production stage of corrugated cardboard from primary semi-finished products. Also the processing conditions of this methodology lead to degradation of the partially hydrolyzed starch. The most complete extraction of starch from corrugated cardboard was achieved by two stages of alkaline extraction under the following conditions: 5 % NaOH, temperature of 20 °C, the duration of each extraction – 2 h. Under these processing conditions it was possible to determine all the starch (22.8 kg/t) in the corrugated cardboard produced of primary semi-finished products with known consumption of starch; the starch content in the corrugated cardboard produced of 100 % waste paper was 48.2 kg/t.

Common juniper (Juniperus communis L.) is one of the most widespread undergrowth species in the forests of Russia. It has not only important silvicultural significance but is also widely used in economic activities. Numerous works of Russian and foreign authors are devoted to its study. The article shows the results of geobotanical and forest inventory studies of a unique area of pine plantation in the Kirillovskiy district of the Vologda region. In the second understorey of which tree-form common juniper grows. The stand was classified as high-density (relative fullness – 0.85) and low quality (quality class – V–IV). The total stock of trunk wood on the site is 280 m3/ha, including the stock of juniper wood – 28 m3/ha. The average diameter of juniper trunks is 14 cm, the average height is 11 m and the age is 180 yrs. This is several times higher than its usual parameters in other forests. A significant number of specimens of juniper (50 pcs/ha) are in the stage of drying out or have already died and represent dead wood of different years. The number of small and medium-sized juniper undergrowth is 1.5 ths pcs/ha or 62.5 % of the growing. Undergrowth of European spruce, downy birch and black alder is also found. The existing undergrowth is assessed as promising, but Scots pine undergrowth is missing. The ground cover is dominated by green and sphagnum mosses as well as shrubs of the Ericaceae and Vacciniaceae families. The study of such objects, extremely rare not only in the north of the European part of Russia, but also everywhere, is of great practical importance. It is also important for understanding the biology of the only representative of the Cupressaceae family that naturally grows here. The tree-form juniper in the pine plantation has survived and reached a size not typical for this species due to the inaccessibility of the site, the lack of fires and forest felling. Such forest areas should be identified, protected, and subjected to stationary research. For citation: Evdokimov I.V., Dobrynin A.P., Armeeva N.A.

A set of parameters of soils under forest belts was studied. The objects of research were old-growth (65–68 yrs) ravine and shelterbelt forest plantations of the Kamennaya Steppe. The results allow assessing the trends of changes in soil characteristics over a long period of time. Key plots of 100×100 m were laid out using a regular sampling grid. The sampling interval is 15–25 m. A positive effect of forest shelterbelts on the properties of chernozems was found. There is an increase in thickness of the humus horizon from 42.3 cm (arable land on the slope) to 72.6±5.1 cm (under forest). The maximum values are typical for chernozems of watershed areas: 59.6±2.4 cm (arable land) and 85.6±3.9 cm (forest belt). Chernozems leached due to the activation of migration processes of carbonates into the underlying soil horizons have the maximum depth of soil effervescence. Chernozems zooturbated due to mechanical transport and mixing of accumulative-carbonate horizon have the lowest depth of soil effervescence. A general trend to decrease the depth of soil effervescence under the forest cenosis was found. The highest humus content is observed in watershed areas: 7.14±0.24 % (arable land) and 8.56±0.18 % (forest belt). A ravine forest belt reduces the risk of erosion processes. A fairly strong humus profile with a high content of organic matter: 7.03±0.27% (under forest) and 6.10±0.10% (on arable land), was possible to preserve on arable lands in the zone of the belt’s influence. The planting of forest belts causes a change in the nature of vegetation. The influence of acidic products of litter decomposition formed soil horizons with a moderately acidic reaction of the environment in the humus layer. Despite the leading position of calcium, an increased content of magnesium was found in the composition of exchange-absorbed cations. Forest belts have become especially important in recent decades due to changing climatic conditions. In the steppe regions of Russia, such plantations are a powerful soil conservation factor that helps stabilize and increase soil fertility. It is necessary to intensify the planting of artificial forest stands in the steppe regions of Russia. For citation: Cheverdin Yu.I., Bespalov V.A., Sautkina M.Yu., Titova T.V.

Published: October 2021

Doubt, Scepticism, and the Dilemma of Establishing the Truth in Middle High German Epic. An Outline of a Research Field The article reflects on the specific uses of doubt as a productive method of ascertaining truth in Middle High German Epic (12th to 14th centuries). Intra-tex­tual debates on the correct interpretation of alternative claims to truth and the presentation of opposing points of view trigger a cognitive and emotional effect of doubt which strongly resonates in metaphors, images and rhetorical figures. Additionally, doubt inspires poetic (and narrative) techniques, motifs and character types which extant research has failed to recognise as interconnected. The purpose of this article is to introduce a research field that is concerned with the analysis of courtly scepticism in secular traditions of literature.

Apie klimato kaitą diskutuojama įvairiais lygmenimis, ieškant būdų taršai sumažinti. Kalbant apie jūrų transporto sektorių, Tarptautinė jūrų organizacija yra iškėlusi tikslą iki 2050 m. sumažinti šiltnamio dujų emisijas iš laivų iki 50 %, palyginti su 2008 m. rodikliais. Šiam tikslui pasiekti analizuojamos amoniako naudojimo perspektyvos dyzeliniuose varikliuose, nes amoniakas neturi anglies atomų ir idealiomis sąlygomis degdamas neišskiria CO2. Ši idėja nėra nauja, atlikti moksliniai tyrimai parodė sėkmingą amoniako naudojimą dvejopo kuro varikliuose, tačiau susiduriama su įvairiomis problemomis, tokiomis kaip NOx, NH3, CO ir kitų emisijų padidėjimas bei variklio energinio efektyvumo sumažėjimas. Šio straipsnio tikslas – įvertinti amoniako naudojimo perspektyvas laivų dyzeliniuose varikliuose ir kartu aptarti kylančias problemas, siekiant sudaryti būsimų mokslinių tyrimų kryptį.

During the current economic growth and the global climate crisis, energy supply is a pressing concern. Local energy sources are an essential part of sustainable development, and they also provide workplaces and energy independence. Various biding legislative documents oblige prioritising renewable energy sources (RES) and focus on green, local energy. Society cannot do such a transition without estimating the available resources and understanding the links among various factors influencing the energy market. The study aims to visualise system dynamics (SD) model parameters using the interactive cartography tool to analyse the potential of renewable energy in Latvia. Data gaps in the model were filled using statistical estimations and ArcGIS Pro spatial analysis. A JavaScript library for interactive maps Leaflet and HTML were used for the graphic user interface. The coupling presented in this paper is not dynamic but provides an insight into the potential implementation of the spatial data into models.

Authors: Lomoko Gideon Masedi Nii Ayi , Paliulis Dainius
Published: October 2021

The purpose of the study underlying the present paper was to determine the adsorption of copper ions which happens to be one of the most important toxic heavy metals in the environment; for that purpose a test was carried out under laboratory conditions using wheat bran as adsorbent. The object of the test was to examine the effect of solution pH, contact time, adsorbent dose and initial copper ions concentration (2 mg/L to 20 mg/L) on adsorption yield and uptake. Three masses of wheat bran (0.5 g, 1.0 g and 2.0 g) were used for this experiment. 1.0 g of wheat bran gave a maximum adsorption efficiency at pH 5.0. At this pH, the adsorption efficiency for initial copper ions concentration of 5 mg/L was found to be 65.8% at room temperature for a contact time of 60 min. The adsorption of copper ions slowly reached equilibrium at 30 mins. With an adsorbent dose of 0.5 g of wheat bran, a maximum uptake of 0.277 mg/g of copper ions was recorded. With increasing mass of adsorbent dose from 0.5 g to 2.0 g. the adsorption uptake of copper ions decreased from 0.273 mg/g to 0.087 mg/g The highest removal efficiency of copper ions was found to be at a metal concentration of 5 mg/L. With the metal concentration increasing the adsorption of copper ions by 0.5 g of wheat bran decreased from 52.0% to 39.9%.

The tight correlations between the mass of supermassive black holes (M
BH) and their host-galaxy properties have been of great interest to the astrophysical community, but a clear understanding of their origin and fundamental drivers still eludes us. The local relations for active galaxies are interesting in their own right and form the foundation for any evolutionary study over cosmic time. We present Hubble Space Telescope optical imaging of a sample of 66 local active galactic nuclei (AGNs); for 14 objects, we also obtained Gemini near-infrared images. We use state-of-the-art methods to perform surface photometry of the AGN host galaxies, decomposing them into spheroid, disk, and bar (when present), and inferring the luminosity and stellar mass of the components. We combine this information with spatially resolved kinematics obtained at the Keck Telescopes to study the correlations between M
BH (determined from single-epoch virial estimators) and host galaxy properties. The correlations are uniformly tight for our AGN sample, with intrinsic scatter 0.2–0.4 dex, smaller than or equal to that of quiescent galaxies. We find no difference between pseudo and classical bulges or barred and nonbarred galaxies. We show that all the tight correlations can be simultaneously satisfied by AGN hosts in the 107–109
M
⊙ regime, with data of sufficient quality. The M
BH–σ relation is also in agreement with that of AGN with M
BH obtained from reverberation mapping, providing an indirect validation of single-epoch virial estimators of M
BH.
The Quest for the Missing Dust. I. Restoring Large-scale Emission in Herschel Maps of Local Group Galaxies

Because the galaxies of the Local Group have such large angular sizes, much of their diffuse, large-angular-scale emission is filtered out by the Herschel data reduction process. In this work, we restore this previously missed dust in Herschel observations of the Large Magellanic Cloud, Small Magellanic Cloud, M31, and M33. We do this by combining Herschel data (including new reductions for the Magellanic Clouds), in Fourier space, with lower-resolution data from all-sky surveys (Planck, IRAS, and COBE) that did not miss the extended emission. With these new maps, we find that a significant amount of emission was missing from uncorrected Herschel data of these galaxies: over 20% in some bands. Our new photometry also resolves the disagreement between fluxes reported from older HERITAGE Magellanic Cloud Herschel reductions and fluxes reported from other telescopes. More emission is restored in shorter-wavelength bands, especially in the galaxies’ peripheries, making these regions 20%–40% bluer than before. We also find that the Herschel-PACS instrument response conflicts with the all-sky data, over the 20′–90′ angular scales to which they are both sensitive, by up to 31%. By binning our new data based on hydrogen column density, we are able to detect emission from dust at low interstellar medium densities (at ΣH < 1 M
⊙ pc−2 in some cases), and are able to detect emission at much lower densities (a factor of 2.2 lower on average, and more than a factor of 7 lower in several cases) than was possible with uncorrected data.

We analyze the effect of polarized diffuse emission in the calibration of wide-beam millimeter-wave polarimeters, when using the Crab Nebula as a reference source for both polarized brightness and polarization angle. We show that, for CMB polarization experiments aiming at detecting B-mode in a scenario with a tensor to scalar ratio r ∼ 0.001, wide (a few degrees in diameter), precise (

We report SOFIA-upGREAT spectroscopic imaging of the [C ii] 158 μm spectral line, as well as a number of [O i] 63 μm spectra, across a 67 × 45 pc field toward the Sgr B region in our Galactic center. The fully sampled and velocity-resolved [C ii] images have 0.55 pc spatial and 1 km s−1 velocity resolutions. We find that Sgr B extends as a coherent structure spanning some 34 pc along the Galactic plane. Bright [C ii] emission encompasses Sgr B1 (G0.5–0.0) and the G 0.6–0.0 H ii region and passes behind and beyond the luminous star-forming cores toward Sgr B2 (G0.7–0.0). Sgr B is a major contributor to the entire Galactic center’s [C ii] luminosity, with surface brightness comparable to [C ii] from the Arches region. [C ii], 70 μm, and 20 cm emissions share nearly identical spatial distributions. Combined with the lack of [C ii] self-absorption, this indicates that these probes trace UV on the near surfaces of more extended clouds visible in CO isotopologues and 160 μm continuum. Stars from regions of local star formation likely dominate the UV field. Photodissociation regions and H ii regions contribute similar amounts of [C ii] flux. The extreme star formation cores of Sgr B2 contribute negligible amounts to the total [C ii] intensity from the Sgr B region. Velocity fields and association with a narrow dust lane indicate that they may have been produced in a local cloud–cloud collision. The cores are likely local analogs of the intense star formation regions where ideas to explain the “C+ deficit” in ultraluminous galaxies can be tested.

We present new spectroscopic observations of the diffuse Milky Way satellite galaxies Antlia 2 and Crater 2, taken as part of the Southern Stellar Stream Spectroscopic Survey (S
5). The new observations approximately double the number of confirmed member stars in each galaxy and more than double the spatial extent of spectroscopic observations in Antlia 2. A full kinematic analysis, including Gaia EDR3 proper motions, detects a clear velocity gradient in Antlia 2 and a tentative velocity gradient in Crater 2. The velocity gradient magnitudes and directions are consistent with particle stream simulations of tidal disruption. Furthermore, the orbit and kinematics of Antlia 2 require a model that includes the reflex motion of the Milky Way induced by the Large Magellanic Cloud. We also find that Antlia 2's metallicity was previously overestimated, so it lies on the empirical luminosity–metallicity relation and is likely only now experiencing substantial stellar mass loss. Current dynamical models of Antlia 2 require it to have lost over 90% of its stars to tides, in tension with the low stellar mass loss implied by the updated metallicity. Overall, the new kinematic measurements support a tidal disruption scenario for the origin of these large and extended dwarf spheroidal galaxies.
