Authors: Laptev A. B. , Naprienko S. A. , , Akhiyarov R. ZH. , Golubev A. V.
Published: January 2022

The problem of using specialized passivating metals and alloys lies in a rather narrow range of the protecting film performance. With a slight change in operating conditions, the film is destroyed and an avalanche-like process of local corrosion begins at the place of film breakdown. A sequence has been developed for determining parts destruction causes, including a sequential analysis of operating conditions; nature of the part destruction; corrosion products composition; phase inversion in the alloy during overheating or mechanical stress in the part.
An Analysis of Two Fluid Layers Enclosed Between Two Non-Porous Surfaces
Authors: Salem Asad
Published: January 2022

The stability of a two-phase interface is a crucial occurrence that involves the design of many engineering applications. It correlates the spatial and droplet size-distributions of many fluid spraying applications and has a great effect on the estimations of the critical heat flux of systems that involves phase change or evaporation. However, the existing hydrodynamic models are only able to predict the stability of a plane fluid sheet, surrounded by an infinite pool of liquid. The case of a thin sheet of liquid surrounding a vapor sheet and enclosed between two walls has not been studied yet. The present paper solves this problem using a linearized stability analysis. Velocity potentials satisfying these conditions are introduced and a complete analysis is presented.

Published: January 2022

Every place on earth has a name. The origin of place names generally has different backgrounds, stories, and histories. Generally, it depends on who gave the name of the place. There is a meaning and purpose behind the naming. This study aims to determine the socio-cultural ecological life of the community in an area and analyze the meaning contained in the socio-cultural context. This qualitative research is sourced from 26 informants. In addition to interviews, this research relies on observation and documentation studies to obtain a comprehensive toponym. This research was conducted at Gedong Tataan. Gedong Tataan is an area where is located that shows the history of transmigration in Lampung during the Dutch colonial period in Indonesia. The results of this study indicate that the naming of Gedong Tataan by the Javanese is influenced by the physical aspects of the area based on the socio-cultural aspect of Java. This study concludes that all areas inhabited by Javanese transmigrants in Lampung have a toponym according to the origin of the population from Java, including the use of the Javanese language for daily communication. This behavior belongs to the realm of cultural preservation and it still thrives in migration and transmigration areas.

Published: January 2022

Multi-biometric system is an advanced technology which has a wide application space in the field of information security. This work proposes the design of a personal identification system based on a combination of biometric inputs such as face, finger vein, iris and fingerprint. Viola jones algorithm is used for face detection. Convolutional neural network (CNN) with different optimisers are used to steeply raise the image texture and extract high definition distinct features of the input images. The deep dream image algorithm accompanies CNN by visualizing these images and by highlighting the image features learnt by the network. These images are used for understanding and diagnosing network behaviour. This network obtains a high recognition rate, which proves to be better performing than traditional algorithms. In addition to these, a high-speed advanced wireless communication technology (Li-Fi) is used in combination with GSM which would act as an alert system that effectively helps in notifying the supervisory authority, if the system is being trespassed without proper authentication.

Authors: Mlayeh Rhouma
Published: January 2022

This paper provides protocols for finitetime average consensus and finitetime stability of systems with controlled nonlinear dynamics innetwork under undirected fixed topology. Each node’s state is a high dimensional vector as a solution of the highly nonlinear first order dynamics with and without drift terms. This paper provides protocols for finitetime average consensus and finitetime stability of systems with controlled nonlinear dynamics innetwork under undirected fixed topology. Each node’s state is high Under the proposed interaction rules, agreements as a common average value or an average trajectory are reached, solving finitetime average consensus and the multisystem equilibrium is controlled leading to the finitetime stability of each system origin. Sufficient conditions are achieved using the Lyapunov techniques and the graph theory. In networked dynamic systems, the theoretical results of the paper cover a large class of underactuated autonomous systems as formation flight, multivehicle coordination, and heterogeneous multisystem behaviors.

Published: January 2022

In this study, the micromorphology of the vegetative
and reproductive structures of the endemic Centaurea
glaberrima Tausch subsp. divergens
(Vis.) Hayek (Asteraceae), using scanning electron microscope (SEM), is
presented for the first time. Uniseriate whip-like non-glandular and biseriate
glandular trichomes are found on the surface of all aboveground parts (stem,
leaves, peduncles, involucral bract). On the adaxial leaf epidermis ribbed
thickenings (striation pattern) of outer periclinal cell walls, slightly curved
anticlinal cell walls and anomocytic stomata are noticed. Rugose abaxial
surface with thorny protuberances of the involucral bract is documented.
Corolla is glabrous with longitudinally parallel epidermal cells with distinct
straight outline. Isopolar, radially symmetric and tricolporate microechinate
pollen grains are seen. Short stylar hairs, without cuticular striations, are
present along the outer sides of the style, while the inner sides (abaxial
surface) constitute the papillate stigmatic surface. Microcharacters found in
cypsela are as follows: slightly ribbed body; rotund base; lateral and concave
insertion; short, unicellular curly acute trichomes; smooth epidermis;
fine-sulcate ornamentation; rod shaped epidermal cells with short, obtuse end
walls and straight anticlinal walls; poorly developed minutely dentate pericarp
rim; and dimorphic pappus with bristles of different length and morphology, with pinnules
restricted to the margins of the bristles. The results obtained contribute to
knowledge about the micromorphology of the studied endemic species and provide
features for its better identification. The taxonomic significance of the analyzed
characters is discussed. Some well defined microcharacters of the studied
species might have taxonomic value.

Late Wenlock graptolite-bearing tuffaceous sandstone from Bomholm, Denmark
Authors: Bjerreskov M. , Jørgensen K.
Published: January 2022

Late Wenlock (Silurian) graptoliferous dark grey mudstone and tuffaceous sandstone lithofacies occur, mainly as loose boulders, at the southeast coast of Bomholm. The mudstone may be estimated to repre­sent a 25 m thick sequence, and contains a graptolite fauna indicating the Cyrtograptus lundgreni Zone. The fauna is correlated with sequences of similar age from other areas, specially from Scania. Monograp-tus flemingi and Pristiograptus dubius pseudodubius are virtually the only species in the tuffaceous sandstone, some of which were deposited by turbidity currents. There is evidence from the taphonomy and diversity of the sandstone graptolites to suggest that the two species lived at a lower level in the water column than other, coexisting species. Size-frequency analyses are inconclusive as to whether or not the fauna in the tuffaceous sandstone represents a rapidly buried life-assemblage. The tuffaceous sandstone samples represent at least 3 airfall water deposited tuff beds and one bed deposited by turbidity current action. Mineral composition and grain-size of the tuffaceous sandstone indicate an origin from plinian eruptions at an estimated distance of about 300 km from Bomholm, and deposition at a depth of 1000 m ± 300 m, on the outer rim of the Fennoscandian platform. The volcanoes were probably situated on a continent south of Bomholm. The eruption centre later may either have disappeared within the Caledo­nian foldbelt or have been displaced by early Palaeozoic large-scale strike-slip faults towards the SE, along the SW border of the East-European craton.
Alcohol-Perturbed Self-Assembly of Tobacco Mosaic Virus Coat Protein
Authors: Abu-Baker Ismael , Blum Amy Szuchmacher
Published: January 2022

Self-assembly of Tobacco mosaic virus coat protein is significantly altered in alcohol-water mixtures. Alcohol cosolvents stabilize the disk aggregate and prevent formation of helical rods at low pH. High alcohol content favours stacked disk assemblies and large rafts, while low alcohol concentration favours individual disks and short stacks. These effects appear to be caused by the hydrophobicity of the alcohol additive, with isopropyl alcohol having the strongest effect, and methanol the weakest. We hypothesize that alcohols interact with the hydrophobic faces of TMV-cp disks, thereby disrupting the protein-protein interactions between disks that are necessary to form helical rods.

Endothelial dysfunction in nonalcoholic fatty liver disease
Authors: PELTEC Angela , ALNABGHALIE Murad
Published: January 2022

Introduction. The prevalence of nonalcoholic fatty liver disease (NAFLD) in western countries is increasing rapidly and is considered as component of metabolic syndrome. Endothelial dysfunction is a pathophysiological problem of cardiovascular disease. NAFLD, as a component of metabolic syndrome, is associated with endothelial dysfunction.

Material and methods. PubMed database was used in order to review and select articles according to the keywords. A total of 216 articles matching search criteria were found between 2000-2021.

Results. The present study has been underlined the role of pathophysiological mechanisms of endothelial dysfunction in nonalcoholic fatty liver disease, which involves oxidative stress, inflammation and insulin resistance. The main factor in the occurrence of endothelial dysfunction is related to nitric oxide (NO) biosynthesis. The markers associated with regulation of nitric oxide biosynthesis, such as asymmetric dimethylarginine, free fatty acid, lectin-like oxidized low-density lipoprotein (LDL) receptor-1 and pentraxin-3, are potential targets in the assessment of endothelial dysfunction.

Conclusions. Insulin resistance, inflammation and oxidative stress have been involved in the reduction of NO biosynthesis that influences the occurrence of endothelial dysfunction. Markers, such as lectin-like oxidized LDL receptor-1 and pentraxin-3, have been considered as potential targets in the assessment of endothelial dysfunctions in NAFLD.

Authors: ESANU Valeriu , PALII Ina
Published: January 2022

Introduction. Deterioration of left ventricular (LV) parameters in Diabetes Mellitus (DM) can occur in the absence of other heart problems. An association between glycosylated hemoglobin (HbA1c) and changes of the LV parameters in DM has been reported. However, data regarding this association model in children with Type 1 Diabetes Mellitus (T1DM) are limited. The purpose of the work was to investigate the association between HbA1c and the LV parameters in pediatric patients.

Material and methods. The study was conducted on 28 children with T1DM ((aged 10 - 18 years, gender M (15)/F (13), duration ≥5 years). The clinical (standard medical examination) and paraclinical (biochemical dosage – HbA1c, echocardiography – LV functional and structural parameters) data was carried out. Statistical analysis  used the SPSS version 20.

Results. The correlational study between the HbA1c and the LV parameters revealed a statistically significant positive correlation coefficient with aortic root diameter (mm) (r=0.7**, p<0.001), left atrium (mm) (r=0.8**, p<0.001 LV diastolic diameter (mm) (r=0.7**, p<0.001), LV systolic diameter (mm) (r=0.7**, p<0.001), septal wall thickness (mm) (r=0.5*, p=0.036), posterior wall thickness (mm) (r=0.5*, p=0.032), LV diastolic volume (ml) (r=0.5*, p=0.025), LV systolic volume (ml) (r=0.6**, p=0.01), ejection fraction (%) (r=0.7**, p=0.001), fractional shortening (%) (r=0.6**, p=0.002).

Conclusions. The results of the study show that in children with T1DM, the increase value of the HbA1c is associated with a consensual and proportional increase in the values of the parameters of the left ventricle.

The aim is to form a balanced position regarding the ergogenic characteristics of new sports food products in the modern practice of training highly qualified athletes on the basis of clinical-experimental evaluation of the effectiveness of special purpose real food additives.

Materials and methods. Studies were carried out on laboratory animals (36 Wistar rats at the age of 3 months weighing 150–200 g and 16 Svetlogorsk mini-pigs) as well as on 102 high-qualified representatives of cyclic sports (all men aged 19–26) − members of national teams such as swimming (25), cross-country athletics (53), and skiing (24). As a control group, we studied 25 athletes of the same gender (all men), age and qualifications who received a placebo (starch capsules) for a long time during exercise. Placebo-controlled studies have been conducted on laboratory animals and athletes in compliance with the principles of bioethics.

Results. It has been established that in the experiment the application of a new specialized food product MioActiv has a positive effect on the physical performance of animals and delays the onset of fatigue, which significantly exceeds the corresponding characteristics in the placebo group. Athletes also showed an increase in speed when passing competitive distances by 18.7–21.4% (p < 0,05), as well as a significant increase in mental endurance indicators (p < 0,05). The approbation of the innovative pre-workout pharmacological nutrient complex Pre-Fuse also showed the high efficacy and safety of this product with a positive effect of increasing the performance and endurance of animals, as well as the parameters of mental performance of athletes in the main groups, in contrast to the data in the placebo control groups.

Conclusions. An analysis of the prescription components of new types of ergogenic sports nutrition and the presented results of preclinical and clinical studies conducted on the basis of the evidence-based medicine paradigm regarding the effectiveness of specialized products indicate the complex action of these funds on various aspects of both physical and mental performance. From the materials presented in the article, it can be seen that specialized sports nutrition products of an ergogenic orientation can provide significant assistance in increasing sports results.

Field investigation carried out by the Sicilian botanists in the last 20 years enabled them to identify eight habitat types of high biogeographic and conservation interest, neglected by the Directive 92/43, which deservead hocconservation measures. For each of these habitats, a syntaxonomic interpretation of the corresponding plant communities, their main ecological, physiognomic and syndynamic traits and a list of diagnostic species are provided. Their classification into the macrotypes listed in the Annex I of the Directive 92/43 and the respective correspondence in EUNIS habitat classification are proposed. The habitats here described integrate those already proposed by the Italian Botanical Society, with the hope of an adequate recognition at national at supranational level.
Wing interference patterns are consistent and sexually dimorphic in the four families of crane flies (Diptera, Tipuloidea)
Authors: Conrow Robert T. , Gelhaus Jon K.
Published: January 2022

Wing interference patterns (WIP) are stable structural colors in insect wings caused by thin-film interference. This study seeks to establish WIP as a stable, sexually dimorphic, species-level character across the four families of Tipuloidea and investigate generic level WIP. Thirteen species of Tipuloidea were selected from museum specimens in the Academy of Natural Sciences of Drexel University collection. One wing from a male and female of each representative species was excised and mounted to a slide with coverslip, placed against a black background, and imaged using an integrated microscope camera. Images were minimally retouched but otherwise unchanged. Descriptions of the WIP for each sex of each species are provided. Twelve of thirteen species imaged had WIP, which were stable and species specific while eight of those twelve had sexually dimorphic WIP. Comparisons of three species of Nephrotoma were inconclusive regarding a generic level WIP. Gnophomyia tristissima had higher intraspecific variation than other species examined. This study confirms stable, species specific WIP in all four families of crane flies for the first time. More research must be done regarding generic-level stability of WIP in crane flies as well as the role sexual and natural selection play in the evolution of wing interference patterns in insects.
Migrations internationales et croissance de la ville de Zurich entre 1836 et 1949
Authors: Lerch Mathias , Guerrouche Karine
Published: January 2022

Le rôle joué par les migrations internationales et leurs interactions avec d’autres composantes démographiques dans le processus de croissance urbaine demeure sous-estimé. Cet article évalue les tendances de l’accroissement naturel et des migrations nettes internes et internationales à Zurich pendant la révolution industrielle, en s’appuyant sur des statistiques historiques ventilées par nationalité et des techniques d’estimations démographiques indirectes. À rebours des théories démographiques sur le rôle prépondérant de l’accroissement naturel dans l’expansion de la ville, ces résultats montrent que l’accroissement naturel n’a été positif qu’en raison de l’apport migratoire. Dans un contexte de déclin précoce de la fécondité, Zurich s’est développée essentiellement sous l’effet des migrations, avec des variations considérables des origines internes et internationales des migrants au cours du temps. La discussion se concentre sur les évolutions structurelles des marchés du travail régional et international, et sur le processus discontinu du développement économique de Zurich et de ses politiques migratoires contrastées.
Éducation et infécondité en Inde
Authors: Baudin Thomas , Sarkar Koyel , Guerrouche Karine
Published: January 2022

L’Inde est un pays en développement où les femmes se sont engagées sur le long chemin de l’émancipation tant au niveau de la famille que de la société. Dans ce contexte, l’infécondité pourrait être perçue comme un signe majeur d’émancipation à l’égard du mariage et de la maternité. En utilisant des régressions à l’échelle individuelle, cet article montre que le rapport entre la probabilité d’une femme de terminer sa vie reproductive sans avoir eu d’enfant et son niveau d’études suit une courbe en U. La pauvreté et la stérilité ne sont donc pas les seuls déterminants de l’infécondité : l’amélioration des perspectives économiques et l’autonomisation au sein du couple comptent également. Ce résultat se maintient après l’introduction de variables de contrôle importantes comme le niveau de développement de l’État où réside la femme, le niveau d’études du mari, l’âge au mariage, la religion et la caste. L’Inde semble rejoindre la liste des pays où les ajustements vis-à-vis de l’infécondité vont bien au-delà d’une simple réaction à l’augmentation ou la diminution de la pauvreté.
Exploring S-shape curves and heterogeneity effects of rumor spreading in online collective actions

Nowadays online collective actions are pervasive, such as the rumor spreading on the Internet. The observed curves take on the S-shape, and we focus on evolutionary dynamics for S- shape curves of online rumor spreading. For agents, key factors, such as internal aspects, external aspects, and hearing frequency jointly determine whether to spread it. Agent-based modeling is applied to capture micro-level mechanism of this S-shape curve. We have three findings: (a) Standard S-shape curves of spreading can be obtained if each agent has the zero threshold; (b) Under zero-mean thresholds, as heterogeneity (SD) grows from zero, S-shape curves with longer right tails can be obtained. Generally speaking, stronger heterogeneity comes up with a longer duration; and (c) Under positive mean thresholds, the spreading curve is two-staged, with a linear stage (first) and nonlinear stage (second), but not standard S-shape curves either. From homogeneity to heterogeneity, the spreading S-shaped curves have longer right tail as the heterogeneity grows. For the spreading duration, stronger heterogeneity usually brings a shorter duration. The effects of heterogeneity on spreading curves depend on different situations. Under both zero and positive-mean thresholds, heterogeneity leads to S-shape curves. Hence, heterogeneity enhances the spreading with thresholds, but it may postpone the spreading process with homogeneous thresholds.

Myocarditis is the form of an inflammation of the middle layer of the heart wall which is caused by a viral infection and can affect the heart muscle and its electrical system. It has remained one of the most challenging diagnoses in cardiology. Myocardial is the prime cause of unexpected death in approximately 20% of adults less than 40 years of age. Cardiac MRI (CMR) has been considered a noninvasive and golden standard diagnostic tool for suspected myocarditis and plays an indispensable role in diagnosing various cardiac diseases. However, the performance of CMR depends heavily on the clinical presentation and features such as chest pain, arrhythmia, and heart failure. Besides, other imaging factors like artifacts, technical errors, pulse sequence, acquisition parameters, contrast agent dose, and more importantly qualitatively visual interpretation can affect the result of the diagnosis. This paper introduces a new deep learning-based model called Convolutional Neural Network-Clustering (CNN-KCL) to diagnose Myocarditis. In this study, we used 47 subjects with a total number of 98,898 images to diagnose myocarditis disease. Our results demonstrate that the proposed method achieves an accuracy of 97.41% based on 10 fold-cross validation technique with 4 clusters for diagnosis of Myocarditis. To the best of our knowledge, this research is the first to use deep learning algorithms for the diagnosis of myocarditis.
Experimental support for the flowing aether concept of gravity

The article of Apffel et al. [Nature 585, 48 (2020)] reported on an experiment that produced the sight of two miniature sailboats floating upside down to each other on the two sides of a layer of glycerol that was levitated by high frequency vibrations. The vessel on the
underside of the glycerol is a remarkable display of the results of simulated gravity caused by vibrations. The present article considers this and other experiments on simulated gravity and finds that they provide support for the flowing aether concept of the cause of gravity.
