Authors: Luo Jinping , Zhou Chenyang , Li Qihang , Liu Lijun
Published: June 2022

Point defects are crucial in determining the quality of germanium crystals. A quantitative understanding of the thermodynamic formation properties of the point defects is necessary for the subsequent control of the defect formation during crystal growth. Here, molecular dynamics simulations were employed to investigate the formation energies, total formation free energies and formation entropies of the point defects in a germanium crystal. As far as we know, this is the first time that the total formation free energies of point defects in a germanium crystal have been reported in the literature. We found that the formation energies increased slightly with temperature. The formation free energies decreased significantly with an increase in temperature due to the increase in entropy. The estimated total formation free energies at the melting temperature are ~1.3 eV for self-interstitial and ~0.75 eV for vacancy, corresponding to a formation entropy of ~15 kB for both types of point defects.

The rheological studies of Lactic Acid (LA)-based Natural Deep Eutectic Solvents (NADES) are provided in the present investigation. Those mechanisms were also studied in which three distinct Hydrogen Bond Acceptors (HBAs) of Choline Chloride (ChCl), Betaine (Be), and β-Alanine (β-Al), after being added to a specific Hydrogen Bond Donor (HBD) at a predefined mole-to-mole ratio of 1:1, affected the rheological properties of the prepared NADES. The alterations in the rheology-related characteristics in association with the mechanical and physical properties indicate the tolerance of the material under various operational conditions in the field and show their potential utilization as environmentally suitable and feasible solvents for industrial applications. In the present research, the viscoelastic properties of the three samples of NADES were assessed along with their shear flow properties. The backward and forward temperature change in the Apparent Viscosity (AV) pattern related to the NADES system was described by a rheogram. Furthermore, the density was determined and compared with the AV while considering the temperature-related factor. On a further note, the viscoelastic characteristics were utilized in describing and investigating the network disturbance on the level of the microstructure of NADES upon frequency sweep. A series of experiments were carried out using Thermogravimetry Analysis (TGA) to investigate the thermo-physical properties to optimize them. The rheological properties of shear flow measurements were analyzed using the Bingham model that is best suited for the AV developed with the shear rate with the dynamic yield stress of three systems. The Bingham model was used to determine the lowest stress necessary to disturb the network structure and commence the flow of LA-based NADES. Overall, the viscoelastic behavior of the LA-based NADES revealed the dissimilarity between their strength and viscosity. In addition, shear flow investigations demonstrated that LA-based NADES systems exhibit non-Newtonian properties and substantial shear-thinning effects equivalent to those of alternative IL sorbents. Assessing the rheological properties of LA-based NADES is crucial for a better understanding the key challenges associated with high viscosity. Defining the transport yield stress requirements for NADES systems under different conditions benefits their future development and potentially opens the door to more challenging applications.

Published: June 2022

Large magnetic field-induced strains can be achieved in modulated martensite for Ni-Mn-In alloys; however, the metastability of the modulated martensite imposes serious constraints on the ability of these alloys to serve as promising sensor and actuator materials. The phase stability, magnetic properties, and electronic structure of the modulated martensite in the Ni2Mn1.5In0.5 alloy are systematically investigated. Results show that the 6M and 5M martensites are metastable and will eventually transform to the NM martensite with the lowest total energy in the Ni2Mn1.5In0.5 alloy. The physical properties of the incommensurate 7M modulated martensite (7M–IC) and nanotwinned 7M martensite (7M−(52¯)2) are also calculated. The austenite (A) and 7M−(52¯)2 phases are ferromagnetic (FM), whereas the 5M, 6M, and NM martensites are ferrimagnetic (FIM), and the FM coexists with the FIM state in the 7M–IC martensite. The calculated electronic structure demonstrates that the splitting of Jahn–Teller effect and the strong Ni–Mn bonding interaction lead to the enhancement of structural stability.

Published: June 2022

Additive Manufacturing (AM) is rapidly evolving due to its unlimited design freedom to fabricate complex and intricate light-weight geometries with the use of lattice structure that have potential applications including construction, aerospace and biomedical applications, where mechanical properties are the prime focus. Buckling instability in lattice structures is one of the main failure mechanisms that can lead to major failure in structural applications that are subjected to compressive loads, but it has yet to be fully explored. This study aims to investigate the effect of surface-based lattice structure topologies and structured column height on the critical buckling load of lattice structured columns. Four different triply periodic minimal surface (TPMS) lattice topologies were selected and three design configurations (unit cells in x, y, z axis), i.e., 2 × 2 × 4, 2 × 2 × 8 and 2 × 2 × 16 column, for each structure were designed followed by printing using HP MultiJet fusion. Uni-axial compression testing was performed to study the variation in critical buckling load due to change in unit cell topology and column height. The results revealed that the structured column possessing Diamond structures shows the highest critical buckling load followed by Neovius and Gyroid structures, whereas the Schwarz-P unit cell showed least resistance to buckling among the unit cells analyzed in this study. In addition to that, the Diamond design showed a uniform decrease in critical buckling load with a column height maximum of 5193 N, which makes it better for applications in which the column’s height is relatively higher while the Schwarz-P design showed advantages for low height column maximum of 2271 N. Overall, the variations of unit cell morphologies greatly affect the critical buckling load and permits the researchers to select different lattice structures for various applications as per load/stiffness requirement with different height and dimensions. Experimental results were validated by finite element analysis (FEA), which showed same patterns of buckling while the numerical values of critical buckling load show the variation to be up to 10%.

Published: June 2022

In this study, some features of molecular dynamics simulation for evaluating the mechanical properties of a Ni/graphene composite and analyzing the effect of incremental and dynamic tensile loading on its deformation are discussed. A new structural type of the composites is considered: graphene network (matrix) with metal nanoparticles inside. Two important factors affecting the process of uniaxial tension are studied: tension strain rate (5 ×10−3 ps−1 and 5 ×10−4 ps−1) and simulation temperature (0 and 300 K). The results show that the strain rate affects the ultimate tensile strength under tension: the lower the strain rate, the lower the critical values of strain. Tension at room temperature results in lower ultimate tensile strength in comparison with simulation at a temperature close to 0 K, at which ultimate tensile strength is closer to theoretical strength. Both simulation techniques (dynamic and incremental) can be effectively used for such a study and result in almost similar behavior. Fabrication technique plays a key role in the formation of the composite with low anisotropy. In the present work, uniaxial tension along three directions shows a big difference in the composite strength. It is shown that the ultimate tensile strength of the Ni/graphene composite is close to that of pure crumpled graphene, while the ductility of crumpled graphene with metal nanoparticles inside is two times higher. The obtained results shed the light on the simulation methodology which should be used for the study of the deformation behavior of carbon/metal nanostructures.

Published: June 2022

This paper is based on the “Fast Pneumatic Mesh Driver” (FPN) used to couple a silicone rubber soft body with a rigid skeleton. A rigid-flexible coupling soft-body human-like finger design scheme is proposed to solve the problem of low load on the soft-body gripping hand. The second-order Yeoh model is used to establish the statics model of the soft humanoid finger, and the ABAQUS simulation analysis software is used for correction and comparison to verify the feasibility of the soft humanoid finger bending. The thickness of the driver cavity and the confining strain layer were determined by finite element simulation. The mold casting process is used to complete the preparation of human-like fingers and design a pneumatic control system for experiments combined with 3D printing technology. The experimental results show that the proposed rigid-flexible coupling soft body imitating the human finger structure can realize the corresponding actions, such as the multi-joint bending and side swinging, of human fingers. Compared with the traditional pure soft-body finger, the fingertip output force is significantly improved. The optimal design and simulation analysis of the human gripper and the feasibility of the application have practical guiding significance.
An Improved Backstepping Controller with an LESO and TDs for Robust Underwater 3D Trajectory Tracking of a Turtle-Inspired Amphibious Spherical Robot

Published: June 2022

In this paper, a double closed-loop backstepping controller is designed for 3D trajectory tracking of a turtle-inspired amphibious spherical robot suffering from problems that include model uncertainties, environmental disturbances, and unmeasured velocity. The proposed controller scheme tackles three primary challenges: the differentiation explosion of the traditional backstepping method, unmeasured velocity, and the consideration of lumped disturbances. Beginning with an outer-loop backstepping controller, a virtual feedback variable is constructed to simplify the design of the backstepping controller. Meanwhile, to avoid the problem of differentiation explosion, tracking differentiators (TDs) are utilized to estimate the differentiation of the desired velocity in an inner-loop backstepping controller. Moreover, there are some uncertainty disturbances in the task of tracking the trajectory of a turtle-inspired amphibious spherical robot (TASR), such as the parameters of the hydrodynamic model and environmental disturbances. A linear extended state observer (LESO) is designed to estimate and compensate for the lumped disturbances. Furthermore, as the velocity states of the TASR are unmeasured, the LESO is also utilized to estimate the velocity states in surge, yaw, and heave degrees. Therefore, the TASR only needs to supply its position and orientation information for the trajectory tracking task. Note that this paper details both the design process of the proposed controller and a rigorous theoretical analysis. In addition, numerical simulations are conducted, and the results demonstrate the feasibility and superiority of the proposed method.

Treponema pallidum subspecies pallidum causes syphilis, a sexually transmitted disease that infects more than 2.1 million pregnant women every year. Due to its maximum death rates and augmented risk of human immunodeficiency virus (HIV) infection, the disease is still a matter of debate in many low- and high-income countries. The infection has three stages that lead to several complications if left untreated and can lead to many tertiary complications in the brain, eyes, ears, heart, and pregnancy. Neurosyphilis is also known as the clinical result of infection of the central nervous system by Treponema pallidum subspecies pallidum. It can evolve at any time and from any stage of syphilis exposure. This review briefly explains the severe and multiple neurosyphilitic complications and recently identified cases related to neurosyphilis. We also explained computational neuroscience, neuroinformatics, and in silico models and techniques based on artificial intelligence and other computational and mathematical methods. These techniques have already been applied to several neurological and psychological brain complications and can be applied to neurosyphilis to better understand the persistence of the disease related to the brain that causes neurosyphilis.
Responding to Food Industry Initiatives to Be "Part of the Solution" Comment on "‘Part of the Solution’: Food Corporation Strategies for Regulatory Capture and Legitimacy"
Authors: Freudenberg Nicholas
Published: June 2022

In response to growing concerns about chronic diseases, food insecurity, low-wage food labor, and global warming, the food industry has developed new strategies to respond to its critics and pursue its business and political goals. As Lacy-Nicholas and Williams described in a recent review, the food industry has expanded its repertoire from opposition to critics to appeasement, co-option, and partnerships.1 Defining themselves as "part of the solution," the food industry seeks to disarm its opponents, shift policy debates to favor its interests, or delay decisions that jeopardize its profits or power. This commentary explores how health professionals, can respond to this changing repertoire. Lessons from previous campaigns to control harmful industry practices,2 suggest that no single strategy will counter changing food industry efforts to achieve its goals. Thus, advocates must consider a portfolio of approaches that can be deployed in response to changing circumstances, industry tactics, and threats to health.
Giros y transiciones. Notas sobre la Historia Cultural en la Argentina
Authors: Bjerg María
Published: June 2022

La historia cultural argentina constituye una zona de indagación híbrida y de fronteras epistemológicas difusas que se configuró a partir tanto de sensibilidades que antecedieron al giro cultural europeo como de lecturas heterodoxas, traducciones locales y adaptaciones críticas de la noción antropologizada de lo cultural. A diferencia de lo que ocurrió en el hemisferio norte, donde la New Cultural History se transformó en la aglutinadora de la actividad académica y terminó por eclipsar a la historia social, en la Argentina la historia cultural funcionó como un agregado más que como un reemplazo de otros modelos analíticos.

Mulheres na década de 1920
Authors: CAVALCANTI Natalia , CASTRO Raimundo
Published: June 2022

Os anos de 1920 produziram profundas mudanças na sociedade brasileira. Primeiro em decorrência das modificações urbanas que levaram a alteração do espaço urbano. Em segundo, a maneira como os homens passaram a ver o comportamento social das mulheres. Por sinal, elas se destacavam, na medida em que passaram a frequentar os espaços antes considerados masculinos. Desafiaram os homens em diversos momentos, seja nas redações de jornais e revistas, seja na realização de atividades consideradas perigosas, como as lutas de boxe ou o salto de paraquedas. As mulheres passaram a questionar a estrutura social. Contudo, nas páginas dos magazines a escrita dos homens imperava sobre como as melindrosas e senhorinhas deveriam se comportar. Numa perspectiva qualitativa e que se utiliza da abordagem presente nos estudos de gênero, nossa pesquisa debruçou-se sobre matérias, ilustrações e crônicas da imprensa de Recife e Belém nos anos 1920 com recorte na história das mulheres.
Normal alkane evaporation under vacuum: chain-length dependency and distillation from binary systems
Authors: Takahashi Daiki , Horike Shohei , Koshiba Yasuko , Ishida Kenji
Published: June 2022

Normal alkanes are among the simplest molecules that can be studied in physical chemistry. However, there is still more to learn about their liquid-to-gas phase transition characteristics, especially in vacuo. Here, we investigated the evaporation behavior of 12 different normal alkanes using thermogravimetry, both in air and under reduced pressures (5000 to 10−2 Pa). The reduced pressures lowered the evaporation-onset temperatures of the normal alkanes. The evaporation-onset temperatures at ∼1 Pa were linearly correlated with the chain lengths (molecular weights). Furthermore, we found that the reduced pressures enabled the effective distillation of binary mixtures of normal alkanes because of the differences in the evaporation-onset temperatures. It was empirically determined that distillation (isolated evaporation of one of the binary mixture components) was achieved at ∼1 Pa when the chain of one of the alkanes was 30% longer than that of the other.

Chiral antiferromagnets are regarded as a new class of antiferromagnets owing to its intriguing spin transport properties such as a sizable anomalous Hall effect (AHE). In this work, we fabricated chiral antiferromagnetic L12-Mn3Ir (111)-oriented films and investigated the anomalous Hall conductivity with respect to the chemical order parameter

S
.

It is found that the anomalous Hall conductivity in (111)-oriented films is much more pronounced compared to (001)-oriented films, which is consistent with the theoretical prediction. We also found that the anomalous Hall conductivity strongly depends on the longitudinal conductivity, which could suggest an extrinsic contribution to the AHE in L12-Mn3Ir.
Breakdown voltage enhancement of p-GaN/AlGaN/GaN diode by controlling Mg acceptors for compensating residual Si donors
Authors: Kawata Soichiro , Zhang Yuwei , Iwata Naotaka
Published: June 2022

Breakdown voltage enhancement was studied for p-GaN/AlGaN/GaN heterostructure diodes, where residual Si donors during growth were compensated with Mg acceptors doped in the p-GaN layer. As the thicknesses of the p-GaN layer (T
p-GaN) decreased from 140 nm, breakdown voltages were increased and maximized at 20 nm, then decreased at 0 nm. Moreover, breakdown voltages of the 20 nm T
p-GaN diodes improved with the increase of the drift region lengths. This is because a uniform electric field was obtained by compensation of the residual Si donors with the Mg acceptors. In addition, for a thicker p-GaN layer, the effects of the surface states were suppressed, and injection of a large number of holes under forward bias was observed. Consequently, the thick p-GaN layer is expected to enhance forward current. Adopting the results, the potential of low on-resistance and high current for p-GaN gated anode diodes was demonstrated.

The research both of the quantity and size structure of the invader Mnemiopsis leidyi (A. Agassiz 1865), as well as the mesozooplankton abundance, species diversity, the food spectrum, trophic relations, and predatory impact by M. leidyi on prey populations in the western and eastern sectors of the open Black Sea was carried out in July - August 2017. M. leidyi biomass varied from 92 to 250 g m during the period of maximum seasonal development. The food spectrum of M. leidyi was dominated by copepods Acartia spp. and Calanus euxinus (Hulsemann 1984). A clear spatial difference in the quantity of M. leidyi and zooplankton, the intensity of food consumption and predatory impact was observed. In the western offshore part of the sea, the high food ingestion rate by M. leidyi (the mean specific daily ration was 45.50±8.31% С) and intensive predatory impact on zooplankton (up to ~50% of Acartia sp. biomass) resulted in the strong decrease in mesozooplankton biomass. In contrast, in the eastern sector M. leidyi predation had no effect on zooplankton community maintaining daily grazing of ~6% Acartia spp. biomass.

Genetic resistance to anticoagulants caused by mutations in the Vkorc1 gene of the most invasive rodent species - Norway rats and house mice - has not been studied in Russia. We analyzed the variability of the Vkorc1 gene in house mice and Norway rats in various settlements of Russia, and identified mutations responsible for resistance to rodenticides. Two exons of the Vkorc1 gene were analyzed in 71 Norway rats from four cities (Moscow, Tyumen, Chita, Rostov-on-Don) and 108 house mice from cities and small settlements (Moscow region, Tormosin, Nizhny Tsasuchei). Three Norway rats (15.8% of the studied individuals) in Moscow have a heterozygous state of the Tyr139Ser mutation, which is responsible for resistance. House mice were not found to have mutations in the Vkorc1 gene responsible for resistance to anticoagulants of the first and second generation in the Leu128Ser and Tyr139Cys positions located in the third exon. However, in cities, we identified two heterozygous mutations in the first exon have not be described previously in scientific literature: Lys58Arg and Ser31Trp. In Russia, the genetic resistance to rodenticides in settlements in the populations of house mice and Norway rats is significantly lower than in Western Europe.
ALIEN AND NATIVE DOMINANTS HAVE A SIMILAR EFFECT ON THE SPECIES RICHNESS OF SYNANTHROPIC PLANT COMMUNITIES OF THE WESTERN CAUCASUS

Published: June 2022

It remains unclear whether alien dominants, on average, have a stronger effect on the species richness of plant communities than native ones. We examined this issue on the example of 20 areas of synanthropic plant communities dominated by species of different biogeographic origin (the study area is the Western Caucasus, the Belaya River valley, 190-680 m above the sea level). Within each of them, samples of aboveground biomass were taken from 25-30 plots of 0.25 m with different coverings of dominants, which were then sorted by species and weighed. Analysis of the data has shown: 1) the average species richness of samples with a similar degree of dominance of alien and native species differs mainly insignificantly; 2) the close relationship between the degree of dominance of alien species and species richness is, on average, about the same as between the degree of dominance of native species and species richness; 3) the relationship between these characteristics in most cases can be satisfactorily explained on the basis of "energy-diversity" hypothesis; 4) the share of synanthropic plant species in communities with high participation of both alien and aboriginal dominants is not higher than in communities with low participation of these dominants. On the whole, our results indicate a similar and predominantly nonselective nature of the impact of alien and native dominants on accompanying species of communities.

Published: June 2022

Under the development of warm phase of climate during the recent decades, large-scale changes in the ranges and numbers of a large number of species of both southern and northern origin have occurred in the Baltic region. Thus, various species demonstrate unsynchronized changes. The population growth of the Caspian Tern ( Hydroprogne caspia ) and its active expansion into the north-western direction were fixed in the 1st half of the XXth century; on the contrary, in the last decades, there is a general trend to number decreasing. This article elaborates on the history of settling of the mentioned species into the Eastern part of the Gulf of Finland, its spatial distribution and peculiarities of biotopic preferences of nesting birds. It is shown that, in contrast to other southern migrants in the region, the Caspian Tern remains a rare species over the past 30-40 years with a tendency to strong fluctuations in number. This is probably caused by the lack of a bird stock in the nearest breeding locations. It has been shown that the stenobiontic species Caspian Tern nests usually in open sandy biotopes. Inhabiting the Gulf of Finland, it mastered reproduction in a completely different landscape on selga massive-crystallic granite rocks.

“Prorubono, vytjagono”. The Philosophy of the Voice in Vladimir Sorokin’s The Factory Committee Meeting
Authors: Ghilarducci Manuel
Published: June 2022

The article investigates the poetics of language in Vladimir Sorokin’s The Factory Committee Meeting from a new point of view. This tale, which dates to the author’s early short prose (1979-1984), has been unanimously regarded as one of the many examples of literary soc–art. Accordingly, the deformed words pronounced in the main event of the text – a collective ritual of violence – have been considered as a device to deconstruct official Soviet ideological discourse (novojaz). However, the neologisms pronounced by the characters (prorubono, vytjagono and others) are not linked to novojaz. Rather, they are arcane words with a strong performative character, which is, paradoxically, linked to the fact that they apparently do not mean anything. In my investigation, I consider these neologisms as a device to deconstruct language as such. Following Mladen Dolar’s philosophy of the voice and Giorgio Agamben’s consideration on the role voice and bare life play in human existence, I regard the deformed words in The Factory Committee Meeting as the literary representation of a point of transition from pure voice / sound (phonē) as the expression of bare life (zōḗ) to the articulated language (logos) which socio-political life (bíos) is based on. I call this liminal stage extimacy (Dolar) and ‘zone of indistinguishability’ (Agamben): a movement of exclusion and, at the same time, inclusion of pure voice and bare life in the logos of the socio-political community.

The article concentrates on the paroimias from the Book of the Prophet Ezekiel, which are intended for liturgical service in the movable commemorations cycle: Ezekiel 1:1-21 for Holy Monday, Ezekiel 1:21-28 for Holy Tuesday, Ezekiel 2:3-3:3 for Holy Wednesday, Ezekiel 37:1-14 for Holy Saturday and Ezekiel 36:24-28 for Pentecost. These are compared based on five text versions occurring between the 9th and 16th centuries: the earliest Old Bulgarian translation in the Parimejnik (9th c.), the Preslav translation of the text with Theodoret of Cyrrhus’s commentary (early 10th c.), the Athonite translation in the Triodion of new redaction (14th c.), the Gennadij Bible (1499) and the Ostrog Bible (1581). The analysis focuses on the variability in the translator’s choice when delivering certain Greek lexemes and specific constructions. The objective is to determine the relation between the content, inherited from the rich previous tradition and the new components in the text of this prophetic book in the Ostrog Bible. Patterns in the preferences for certain variants in the different versions are systematized. 

The analysis makes it possible to conclude that the Ostrog Bible may be considered most closely linked to the Gennadij Bible and the Preslav translation of the text with commentaries. The studied materials evidence an increased influence on the text of the first Slavonic printed Bible by the Athonite translation in the Triodion of new redaction in the three paroimias for the Holy Monday, Tuesday and Wednesday. In the other two readings, however, this trend is insignificant. The presence, on one hand, of isolated lexical occurences of collation of the text with Greek sources, and on the other, of instances of uncritical carrying-over of inaccuracies from the older Slavonic versions, shows the unsystematic editorial approach of the scholars from the Ostrog academic circle.
The Names of the Unknown Soldiers. Soviet War Literature and Journalism, or Verisimilitude and Truth: Two Case Studies
Authors: Colombo Duccio
Published: June 2022

Vasilij Subbotin’s We Stormed the Reichstag is a typical specimen of the wave of non-fiction prose about World War II which sprang up in the wake of the 20th Congress. The search for the unjustly forgotten war hero, one of the major themes of this kind of literature, is represented here by the story of Pëtr Pjatnickij, a soldier who fell on the steps of the Reichstag entrance with a red flag in his hand and was then forgotten.

If, hypothetically, this story was false, it would echo the (probably false) story of the 28 ‘panfilovcy’ who purportedly fell at Dubosekovo during the battle for Moscow. In that case, Subbotin’s text would embody a characteristically literary device: giving a name to an anonymous character, the anonymous figure, for example, carrying the flag in Vladimir Bogatkin’s well-known painting, as a way to give life and credibility to the image. The Dubosekovo story, as developed by journalist Aleksandr Krivickij, appears to employ the same mechanism for achieving credibility. In this case the operation was twofold: Krivickij gave his heroes first a number, and only later names. The second move was the most hazardous. A story that pretends to be true must be verifiable in real life; this is where Krivickij failed and where Subbotin may have succeeded.

Stalinist culture fundamentally refused to separate fact from fiction. The non-fiction literature from the Thaw is exactly the opposite: an attempt at reinstating the separation.
Orthography of the Handwritings of the 12th Century Lazarevskij Paroemiarion
Authors: Molkov Georgiy Anatolyevich
Published: June 2022

The Lazarevskij Paroemiarion (Parimejnik) is the earliest copy of this liturgical book in the Old Church Slavonic translation; according to the latest research, it dates back to the middle of the 12th century. This manuscript has East Slavic origins and contains important information on the history of Old Russian orthography. Three scribes contributed to the creation of the manuscript and their spelling varies in many respects.
Innovative spelling associated with phonetic changes in the Old Russian language of the 12th century are concentrated in the first handwriting: the number of stems with jer omissions, positions with the change of strong jers into o or e, and examples of the so-called “new jat’ (ѣ)”. This handwriting determines the dating of the manuscript. The second scribe also took part in the writing of another Old Russian manuscript, the Miljatino Gospel. The analysis of his part of the Lazarevskij Paroemiarion makes it possible to assess the degree of variability of spelling preferences of the same scribe when working on copies of different texts.  The third handwriting looks archaic in the writing of weak jers and the use of non-contracted variants of adjective inflections, although in other positions South Slavicisms can be completely eliminated from it (compare the absence of žd for the reflex of *dj when using žd in the first and second handwritings).
Of the coincidences in the spelling of the scribes, the most interesting is the spelling specificity in the recording of specific word forms and letter combinations. These coincidences, indicative against the background of the general inconsistency and spelling differences of the three handwritings, can be attributed to the specifics of the spelling of the scriptorium at the Lazarev Monastery, in which the Parimejnik was rewritten. These characteristic features of the scriptorium include the isolation in the recording of the adverb-preposition posrědě, the dative and local case forms of the pronouns tebě, sebě, only in the form of tebe, sebe, the influence of the same graphic clichés on the choice of the affricate letter.

Published: June 2022

Background: Acute aortic dissection is a medico-surgical emergency that is associated with a poor prognosis, especially when complicated by malperfusion syndrome. Purpose: The objective of our study was to assess the prognosis and management of aortic dissection complicated by malperfusion syndrome. Methods: Retrospective study from December 2017 to October 2019 including 4 patients hospitalized for aortic dissection with malperfusion syndrome operated at the Ibn Sina University Hospital. The diagnosis was made on clinical, biological and CT scans. Results: Patients’ mean age was 65.75 ±11,5 years with a sex ratio M / F of 1/3. Hypertension was the main risk factor and was found in all patients, only one of our patients was a smoker. The organs affected by malperfusion are divided as follows: Two (02) cases of lower limb malperfusion, two (02) cases of digestive malperfusion, one case of renal malperfusion, one case of cerebral malperfusion and one case of myocardial malperfusion. The management was surgical. Three patients underwent supracoronary tube placement and one patient underwent Bentall's procedure. Aorto-coronary bypass, an axillofemoral bypass and a cross bypass were performed to remove myocardial and lower limbs malperfusions. Mortality at one month was 50%, with one patient dying in-hospital from cardiogenic shock and one patient dying at one month from lower limb gangrene. Conclusion: Surgery is still relevant in managing aortic dissection associated with malperfusion. In our study, the survival at one month was 50%, suggesting the necessity to improving our management of aortic dissection when associated with malperfusion.
Specificities of Oral Verrucous Carcinoma: Case Report and Literature Review

Published: June 2022

Introduction: Verrucous carcinoma of the oral mucosa recurs locally but does not metastasize in the absence of an invasive squamous cell carcinoma component. Clinical Observation: We report a case of an oral verrucous carcinoma in 67-year-old male patient causing bone invasion and bilateral lymph node metastasis despite the absence of a clear squamous cell carcinoma component. Discussion: Some verrucous carcinomas show dysplasia with very minor component of conventional squamous cell carcinoma. Currently, there is great challenge in diagnosing those “in between” tumor type because of the lack of standard nomenclature and studies assessing their clinical behavior.
Invasive Trichosporonosis in Immunocompetent Patient, a Case Report and Review of Literature

Published: June 2022

Trichosporonosis is an uncommon fungal infection that affects immunocompromised patients and has a very poor prognosis. We present a case of a 23 years-old immunocompetent patient with a history of tuberculous lymph nodes. We observed the patient from admission until discharge from the hospital. There are several diagnostic and therapeutic difficulties. Clinical symptoms and radiological findings may vary according to the affected organ. Symptoms may reflect either superficial or deep infection. Diagnosis is based on microscopic study and culture of superficial specimen. In deep infections, identification of Trichosporon spp. depends on biochemical characteristics and cell morphology. Radiological imaging is most important to assess lesion extension. Several evolutions without treatment is recognized due to this disease and his complications. The patient died despite being on fluconazole treatment which confirms the reserved prognosis of the pathology reported in the literature. Several evolutions without treatment is recognized due to this disease and his complications. W. ithout treatment, the evolution occurs in more than 80% of cases towards death. Special attention should be paid to this pathology.

Spontaneous rupture of the bladder after a vaginal delivery is an extremely rare situation. We report the case of a 32-year-old female patient who, after a vaginal delivery, presented persistent abdominal pain associated with hematuria followed by an anuria. The exaggeration of abdominal pain associated with a gradual increase in the volume of the abdomen have motivated abdominopelvic ultrasound and an injected uroscan with acquisition at the late time confirmed the diagnosis of bladder rupture that was clinically presumed, showing a finely echogenic great abundance peritoneal effusion on ultrasound, an intact uterus and contrast product extravasation outside the bladder. Its etiology is multifactorial incriminating hyperpressure of the fetal head on the bladder not previously emptied during the second phase of labor in addition to the bladder wall weakening factors. Bladder evacuation is recommended during the second phase of labor to avoid any risk of rupture.
Selection of Cluster Head in Wireless Sensor Network using Convolution Neural Network Algorithm
Authors: Krishnaraj N.
Published: June 2022

Network lifetime enhancement is one of the primary goals for all the Wireless Sensor Network (WSN) applications. Clustering process helps the WSNs to improve its lifetime by forming a group with nearby sensor nodes. A primary node called cluster head is elected from the group for managing the data transmission from the other clustering groups to the basic sensor nodes. Also, the cluster heads are placed to transfer the signal collected from its sensor nodes to the base stations. Identifying an optimum node for making it as a cluster head is a challengeable process for many WSN applications. The proposed work is employed with a neural network algorithm for electing a cluster head by analyzing the residual energy, base station distance and neighbor sensor counts. The experimental work carried out in the paper indicates a betterment on survival node time and energy consumption.
