Phyllotheca douroensis sp. nov., a new equisetalean fossil-species from the Douro Carboniferous Basin (Upper Pennsylvanian; NW Portugal): palaeobiogeographical, systematic and evolutionary implications
Authors: Barbosa Catarina , Correia Pedro , Muchagata João , Domingos Rúben , Sá Artur A.
Published: March 2022

The first occurrence of the fossil-genus Phyllotheca (Equisetales) from the Carboniferous of Portugal is documented and its palaeobiogeographical, systematic and evolutionary significance is assessed. In this paper, we described this new equisetalean fossil as new species, Phyllotheca douroensis sp. nov., found in the Douro Carboniferous Basin (lower Stephanian C/lower Gzhelian, Upper Pennsylvanian), in northwestern Portugal. P. douroensis sp. nov. represents a convergent form of Phyllothecaceae sensu lato (comprises the Angaran Tchernoviaceae and the Gondwanan Gondwanostachyaceae) with closer affinities to Euramerican floral province.
The role of state and public administration in the processes of interaction of "dry" and sea ports
Authors: Troilin Vladimir V. , Arustamov Igor A.
Published: March 2022

"Dry ports" are widely used in the transport system of the Russian Federation. At the same time, Russian legislation does not define the concept of “dry port administration” as a body that manages it, which negatively affects its interaction with government and commercial structures, the society at its location. The authors, using the tools of comparative analysis, implemented reasonable methodological approaches to the study of internal and external factors of the functional profile and geographic positioning, on the basis of which three options for a hypothetical typology of the authorities of the “dry port” were developed and proposed and the concept was formulated: “administration of the “dry port”.
Analysis of the causes and areas of localization of wear of the outer plating of the hulls of inland and mixed (river-sea) navigation
Authors: Burmistrov Evgeny G. , Kromov Dmitry A.
Published: March 2022

This article analyzes the areas of localization of wear of the outer plating of the hulls of ships of inland and mixed (river-sea) navigation and the causes of them. It is noted that the problem of wear of outer plating sheets is associated with the tasks of ensuring watertightness and strength of ship hulls, on which the preservation of the functionality of ships as floating transport engineering structures depends. The results of the study show that: 1) wear of the outer skin of the vessels of inland and mixed (river-sea) navigation of the studied groups (pusher tugs, oil ore carriers, dry cargo and passenger ships) have different localization; 2) the localization of wear depends on the area of ​​operation, the main dimensions and design features of the ships; 3) wear is caused by corrosive, erosive and abrasive effects of the external environment, structural changes in the metal in welds and near-weld zones, as well as poor quality of paint and varnish protection of ship hulls, insufficient vibration damping of ship mechanisms, in some cases, unsatisfactory alignment of ship mechanisms and shafting; 4) local residual deformations (dents, crooks, ribbing), the frequency of their formation, the appearance and development of cracks in welds and the whole metal are due to the loss of stability of bonds due to their wear; 5) there is a correlation between the wear values and residual deformations of the outer skin sheets. Establishing the type of correlation dependence requires special study.

Prospects for Measuring Off-axis Spins of Binary Black Holes with Plus-era Gravitational-wave Detectors
Authors: Knee Alan M. , McIver Jess , Cabero Miriam
Published: March 2022

The mass and spin properties of binary black holes (BBHs) inferred from their gravitational-wave signatures reveal important clues about how these systems form. BBHs originating from isolated binary evolution are expected to have spins preferentially aligned with their orbital angular momentum, whereas there is no such preference in binaries formed via dynamical assembly. The fidelity with which near-future gravitational-wave detectors can measure off-axis spins will have implications for the study of BBH formation channels. In this work, we examine the degree to which the Advanced LIGO Plus (A+) and Advanced Virgo Plus (AdV+) interferometric detectors can measure both aligned and misaligned spins. We compare spin resolution between the LIGO-Virgo network operating at either A+/AdV+ (“Plus”) sensitivity or Advanced-era design (“Design”) sensitivity using simulated BBH gravitational-wave signals injected into synthetic detector noise. The signals are distributed over the mass-spin parameter space of likely BBH systems, accounting for the effects of precession and higher-order modes. We find that the Plus upgrades yield significant improvements in spin estimation for systems with unequal masses and moderate or large spins. Using simulated signals modeled after different types of hierarchical BBH mergers, we also conclude that the Plus detector network will yield substantially improved spin estimates for 1G+2G binaries compared to the Design network.
Assessing the Importance of Noise from Thermal Sunyaev–Zel′dovich Signals for CMB Cluster Surveys and Cluster Cosmology
Authors: Raghunathan Srinivasan
Published: March 2022

We explore the significance of noise from thermal Sunyaev–Zel’dovich (tSZ) signals for cluster detection using cosmic microwave background (CMB) surveys. The noise arises both from neighboring objects and also from haloes below the detection limit. A wide range of surveys are considered: SPT-SZ, SPTpol, and SPT-3G from the South Pole Telescope; SO-Baseline and SO-Goal configurations for Simons Observatory; CMB-S4's wide-area (S4-Wide) and deep (S4-Ultra deep) surveys; and the futuristic CMB-HD experiment. We find that the noise from tSZ signals has a significant impact on CMB-HD and to some extent on S4-Ultra deep. For other experiments, the effect is negligible as the noise in the tSZ map is dominated by residual foregrounds or experimental noise. In the limit when the noise from tSZ signals is important, we find that removing the detected clusters and rerunning the cluster finder allows us to find a new set of less massive and distant clusters. Since the detected clusters are the dominant source of the tSZ power, removing them reduces the power at ℓ = 3000 by ×5 for CMB-HD; ×3.1 of S4-Ultra deep; ×2.4 for S4-Wide and SPT-3G; ×1.5 for SO-Goal and SPTpol; ×1.35 for SO-Baseline; and ×1.08 for SPT-SZ. We forecast the expected number of clusters and also derive parameter constraints by combining cluster counts with primary CMB and tSZ power spectra finding that the future surveys can reduce the error on the dark energy equation of state parameter to sub-percent levels and can also enable ≥3σ detection of the sum of neutrino masses.

Detectability of Black Hole Binaries with Gaia: Dependence on Binary Evolution Models
Authors: Shikauchi Minori , Tanikawa Ataru , Kawanaka Norita
Published: March 2022

The astrometric satellite Gaia is expected to observe noninteracting black hole (BH) binaries with luminous companions (LCs; hereafter BH-LC binaries), a different population from BH X-ray binaries previously discovered. The detectability of BH-LC binaries with Gaia might be dependent on binary evolution models. We investigated the Gaia's detectability of BH-LC binaries formed through isolated binary evolution by means of the binary population synthesis technique and examined its dependence on single and binary star models: supernova models, common envelope (CE) ejection efficiency α, and BH natal kick models. We estimated that 1.1–46 BH-LC binaries can be detected within the five-year observation, and found that α has the largest impact on the detectable number. In each model, observable and intrinsic BH-LC binaries have similar distributions. Therefore, we found three important implications: (1) if the lower BH mass gap is not intrinsic (i.e., 3–5 M
⊙ BHs exist), Gaia will observe ≤5 M
⊙ BHs; (2) we may observe short orbital period binaries with light LCs if CE efficiency is significantly high; and (3) we may be able to identify the existence of natal kick from eccentricity distribution.
Insight-HXMT, NuSTAR, and INTEGRAL Data Show Disk Truncation in the Hard State of the Black Hole X-Ray Binary MAXI J1820+070
Authors: Zdziarski Andrzej A. , You Bei , Szanecki Michał , Li Xiao-Bo , Ge Mingyu
Published: March 2022

We study X-ray and soft gamma-ray spectra from the hard state of the accreting black hole binary MAXI J1820+070. We perform an analysis of joint spectra from HXMT, NuSTAR, and INTEGRAL. We find an overall agreement between the spectra from all three satellites. Satisfactory fits to the data require substantial spectral complexity, with our models including two Comptonization regions and their associated disk reflection, a disk blackbody, and a narrow Fe Kα line. Our fits confirm the presence of the truncation of the reflecting optically thick disk at least at >10 gravitational radii. However, we find that the HXMT data alone cannot significantly constrain the disk inner radii.
Very Local Interstellar Medium Revealed by a Complete Solar Cycle of Interstellar Neutral Helium Observations with IBEX

The IBEX-Lo instrument on board the Interstellar Boundary Explorer (IBEX) mission samples interstellar neutral (ISN) helium atoms penetrating the heliosphere from the very local interstellar medium (VLISM). In this study, we analyze the IBEX-Lo ISN helium observations covering a complete solar cycle, from 2009 through 2020 using a comprehensive uncertainty analysis including statistical and systematic sources. We employ the Warsaw Test Particle Model to simulate ISN helium fluxes at IBEX, which are subsequently compared with the observed count rate in the three lowest energy steps of IBEX-Lo. The χ

HP = 25.86 ± 0.21 km s−1 and temperature T
HP = 7450 ±140 K at the heliopause. Accounting for gravitational attraction and elastic collisions, the ISN helium speed and temperature in the pristine VLISM far from the heliopause are v
VLISM = 25.9 km s−1 and T
VLISM = 6150 K, respectively. The time evolution of the ISN helium fluxes at 1 au over 12 yr suggests significant changes in the IBEX-Lo detection efficiency, higher ionization rates of ISN helium atoms in the heliosphere than assumed in the model, or an additional unaccounted for signal source in the analyzed observations. Nevertheless, we do not find any indication of the evolution of the derived parameters of ISN helium over the period analyzed. Finally, we argue that the continued operation of IBEX-Lo to overlap with the Interstellar Mapping and Acceleration Probe will be pivotal in tracking possible physical changes in the VLISM.
The first checklist of alien vascular plants of Kyrgyzstan, with new records and critical evaluation of earlier data. Contribution 2
Authors: Sennikov Alexander , Lazkov Georgy
Published: March 2022

We continue the inventory of alien vascular plants of Kyrgyzstan, with emphasis on the time and pathways of introduction of the species and their current status in the territory. Each taxon is discussed in the context of plant invasions in Central Asia. This work is a further development of the preliminary checklist of alien plants of Kyrgyzstan, which was compiled for the Global Register of Introduced and Invasive Species in 2018.

This contribution includes all alien species of Kyrgyzstan belonging to Solanaceae and Asphodelaceae and one species of Asteraceae. Physalis philadelphicus (syn. P. ixocarpa) is reported for the first time from Central Asia, as new to Kazakhstan, Kyrgyzstan and Uzbekistan, thus marking a recent invasion with a variety of imported grain and seed material. The old records of P. ixocarpa from Uzbekistan are based on misidentified specimens of P. angulata. Physalis angulata is an old cotton immigrant in Central Asia, whose invasion started in the 1920s; it is excluded from the alien flora of Kyrgyzstan as registered in error on the basis of cultivated plants. Alkekengi officinarum is an archaeophyte of the Neolithic period in Central Asia, formerly used for food, now strongly declining and largely casual in Kyrgyzstan. The only historical record of Physalis viscosa from Uzbekistan was based on a technical error and belongs to A. officinarum. Datura stramonium and Hyoscyamus niger were introduced as medicinal plants during the period of the Arabic invasion of Central Asia, by the 11th century. Datura innoxia is a newly recorded casual alien, recently escaped from ornamental cultivation. Nicandra physalodes is a casual alien, which was cultivated by Russian colonists in the early 20th century for culinary use and is currently used in ornamental cultivation. Hemerocallis fulva was a remnant of historical cultivation in the former Khanate of Buxoro, and its formerly established colonies are presumably extinct in the wild. Bidens frondosa was seemingly introduced with contaminated forage and seed of American origin during the late Soviet period and started to spread in the period of independence; its invasion in the former USSR is analysed.
The development of a novel ultrashort antimicrobial peptide nanoparticles with potent antimicrobial effect
Authors: Salama Ali
Published: March 2022

Conventional antibiotics are facing significant microbial resistance, which has recently reached previously unnoticed critical levels. As a result of this situation, a large proportion of antimicrobial agents currently used in the clinic have significantly reduced therapeutic potential. Antimicrobial peptides (AMPs) may offer the medical community an alternative strategy to traditional antibiotics in the fight against microbial resistance. Current research efforts are focused on developing technologies that may reduce AMP toxicity while retaining their potent antimicrobial activity and possibly improving their delivery. The ionotropic gelation method was used to encapsulate a novel in-house designed potent ultrashort antimicrobial peptide (USAMP) into chitosan-based nanoparticles (CS-NPs) in this study. WRWRWR -CS-NPs were tested for antibacterial kinetics against two strains of Staphylococcus aureus for four days, and the developed WRWRWR -CS-NPs showed a 3-log decrease in the number of colonies when compared to CS-NP and a 5-log decrease when compared to control bacteria. Loaded WRWRWR into CS-NPs could represent an innovative approach to develop delivery systems based on NPs technology for achieving potent antimicrobial effects against multi-drug resistant and biofilm forming bacteria with negligible systemic toxicity and reduced synthetic costs that are obstructing the clinical development of AMPs generally.
Description of immature stages of Gymnetron species (Coleoptera, Curculionidae, Curculioninae), with particular emphasis on the diagnostic morphological characters at the generic and specific levels

Published: March 2022

The immature stages of the following five PalaearcticGymnetronspecies are described for the first time:G. tibiellumDesbrochers des Loges, 1900,G. veronicae(Germar, 1821),G. rotundicolleGyllenhal, 1838,G. melanarium(Germar, 1821), andG. villosulumGyllenhal, 1838. These species belong to four different groups previously established according to a phylogenetic analysis: the first two belong to theG. veronicaegroup and the other three to groups respectively bearing their name (G. rotundicolle,G. melanarium, andG. villosulumgroups). All these species exhibit several diagnostic characters distinguishing them from each other. Some characters that can be used to separateGymnetronfrom other genera in the tribe are also suggested. Three highly significant characters for the larvae and three for the pupae were identified. For the larvae they are: (1) labial palpi with single palpomeres, (2) all spiracles unicameral, and (3) epipharynx with a single pair ofmesor none at all. For the pupae they are: (1) the pronotum with prominent pronotal protuberances, (2) abdominal segment VIII with a conical abdominal protuberance dorsally, and (3) very short or even reduced urogomphi. The species studied here are compared with thoseGymnetronspecies already known and with other genera in the tribe Mecinini. Keys to the larvae and pupae described here are provided. All the characters used for identification are illustrated by photographs or drawings.
A new genus name for pygmy lorises, Xanthonycticebus gen. nov. (Mammalia, primates)
Authors: Nekaris K. Anne-Isola , Nijman Vincent
Published: March 2022

Lorisiformes are nocturnal primates from Africa and Asia with four genera, with two (Arctocebus and Loris), three (Perodicticus) and nine (Nycticebus) recognised species. Their cryptic lifestyle and lack of study have resulted in an underappreciation of the variation at the species and genus level. There are marked differences between the pygmy slow loris Nycticebus pygmaeus and the other Nycticebus species and, in the past, several authors have suggested that these may warrant recognition at the generic level. We here combine morphological, behavioural, karyotypical and genetic data to show that these contrasts are, indeed, significantly large and consistent. We propose Xanthonycticebus gen. nov. as a new genus name for the pygmy slow lorises and suggest a common name of pygmy lorises. Based on analysis of complete mitochondrial DNA sequences, we calculate the divergence of pygmy from slow lorises at 9.9–10.0%. The median date, calculated for the divergence between Xanthonycticebus and Nycticebus, is 10.5 Mya (range 4.9–21.0 Mya). Xanthonycticebus differs from Nycticebus by showing sympatry with other slow loris species, by habitually giving birth to twins, by showing seasonal body mass and whole body coat colour changes (absent in other species living at similar latitudes) and a multi-male, multi-female social system. Pygmy lorises are easily recognisable by the absence of hair on their ears and more protruding premaxilla. Xanthonycticebus is threatened by habitat loss and illegal trade despite legal protection across their range and all slow lorises are listed on appendix 1 of CITES. The suggested nomenclatural changes should not affect their legal status.
Living with Schizophrenia: A Family Perspective
Authors: Brady Noreen , McCain Gail
Published: March 2022

The lifetime emotional, social, and financial consequences experienced by individuals with schizophrenia have significant effects on their families. Family responses to having a family member with schizophrenia include: care burden, fear and embarrassment about illness signs and symptoms, uncertainty about course of the disease, lack of social support, and stigma. Study findings about families in which parents are hostile, critical, or overly involved are equivocal about whether this negative environment contributes to patient relapse. This review summarizes the studies related to the family responses and emotional environment of families who have a member with schizophrenia.
The Need for Some Sense Making: Doctor of Nursing Practice
Authors: Fulton Janet , Lyon Brenda
Published: March 2022

The American Association of Colleges of Nursing has developed a general proposal for a practice doctorate for nursing and the National Organization of Nurse Practitioner Faculties has developed a proposal for the practice doctorate for nurse practitioners. This article describes the current initiative for developing the practice doctorate and argues that the proposed practice doctorates raise substantial concerns for the discipline of nursing. The concerns addressed in this article include the rationale offered for the new degree, confusion over the focus of the degree, the impact of the degree on educational and economic resources for both students and employers, and the regulatory issues arising from the implementation of the degree. The authors recommend thorough debate by all involved stakeholders before moving forward with this degree.
Dernières nouvelles de l'équité
Authors: Mazabraud Bertrand
Published: March 2022

Le juge, dans l'application des normes juridiques, devrait s'effacer pour ne pas interférer entre la loi et le cas. Cette idéologie commune et ancienne devrait conduire en toute rigueur à se passer du juge, tant sa subjectivité menace l'économie des valeurs promues par un tel système : égalité, sécurité, efficacité. Or la logique de cette idée repose sur des présupposés intenables : la transparence des énoncés normatifs, un déni de la contingence et de la variabilité des situations humaines. S'il est encore besoin de juges plutôt que d'automates ou de robots, c'est que pour juger, il faut comprendre les justiciables et les lois. Comprendre les justiciables suppose que l'on puisse se mettre à leur place. Comprendre les lois suppose une équité herméneutique. Et ces deux conditions contribuent à l'acceptabilité morale des décisions de justice. Mais dès lors, le jugement judiciaire opère plus ou moins, selon le cas, une transaction entre les valeurs instrumentales du droit (sécurité, efficacité…) et les valeurs morales promues par le droit. Cette transaction se dénommait hier : équité ; et aux dernières nouvelles, elle se nomme « équilibre des intérêts » ou « proportionnalité ». Sa question morale demeure : jusqu'à quel point les différences saillantes des situations justifient que l'exception s'intègre aux applications communes des règles ?

The influence of market factors on the potential environmental benefits of the recycling of rare earth elements
Authors: Schrijvers Dieuwertje L. , Loubet Philippe , Sonnemann Guido W.
Published: March 2022

After the rare earth element (REE) crisis in 2011, companies invested in new supply routes of REEs, such as the recycling from end-of-life fluorescent lamps. Although recycling is in the current market situation not economically profitable anymore, it does fit in a strategy towards a low-carbon and a circular economy, for example to mitigate the supply risk of REEs. However, is recycling of REEs indeed environmentally beneficial? Should their recycling therefore be subsidized? This is assessed with a Consequential Life Cycle Assessment (CLCA). The results show that the answer to this question strongly depends on the market situation of the REEs, and the applications in which they are used. At the time that the recycling process was operating—where fluorescent lamps could still displace halogen lamps and there was sufficient demand for the REE europium and yttrium—environmental benefits could be achieved by increasing the recovery of REEs from end-of-life fluorescent lamps. The results of this study can be used to increase the understanding on the type of market interactions that could be considered in the decision-making processes regarding the supply and recycling of raw materials—especially materials that are often produced as by-products, such as many critical raw materials.
The parameter-Newton iteration for the second-order cone linear complementarity problem
Authors: Zhou Peng , Wang Teng
Published: March 2022

In this paper, we propose the parameter-Newton (PN) method to solve the second-order linear complementarity problem (SOCLCP). The key idea of PN method is that we transfer the SOCLCP into a system of nonlinear equations by bringing in a parameter. Then we solve the system of nonlinear equations by Newton method. At last, we prove that the PN method has quadratic convergence. Compared with the bisection-Newton (BN) method, the PN method has less CPU time and higher accuracy in numerical tests.
Levenberg-Marquardt method for identifying Young's modulus of the elasticity imaging inverse problem
Authors: Abdelhamid Talaat , Khayat F. , Zayeni H. , Chen Rongliang
Published: March 2022

The present study focuses on reconstructing the Young's modulus for the elasticity imaging inverse problem. It is a very interesting and challenging problem encountered in tumor detection where the variation of the elastic properties of soft tissues allows to distinguish between normal and diseased tissues. The Levenberg-Marquardt method is used to treat this ill-posed inverse problem and the non-convex minimization is changed into a convex one. We get an explicit expression for computing the descent direction. The proposed technique with a constant and space dependant coefficients and for various real materials is examined. The obtained results of the 2D and 3D view for the reconstructed Young's modulus are agree with those of the exact coefficients. The proposed algorithm is implemented for different levels of noise in the data.

Amicizia tra cardinali curiali : il « caso » Gasparri, Pacelli, Tedeschini
Authors: Cárcel Ortí Vicente
Published: March 2022

Federico Tedeschini, nunzio apostolico a Madrid dal 1921 al 1936 (creato cardinale nel 1935) ebbe una lunga e stretta amicizia con i cardinali Pietro Gasparri e Eugenio Pacelli, segretari di Stato di Pio XI. Tale amicizia era nata durante il pontificato di Benedetto XV, del quale Gasparri fu segretario di Stato, mentre Tedeschini era sostituto della Segreteria di Stato e Pacelli segretario della Congregazione degli Affari Ecclesiastici Straordinari. L’articolo analizza i rapporti di amicizia tra i tre durante gli anni della lunga nunziatura di Tedeschini in Spagna, in particolare in occasione del suo scontro personale con il cardinale Segura, arcivescovo di Toledo. Severamente criticato da alcuni cardinali della Curia per il suo atteggiamento ostile verso il primate della Spagna, Tedeschini fu apertamente difeso dai sui amici, che valutarono le difficoltà della sua missione diplomatica.
Gli intonaci. Corsi e ricorsi « Funzionali »

Published: March 2022

Il fenomeno del reimpiego dei materiali edilizi si configura come una tecnica piuttosto diffusa nell’antichità, dettata da esigenze di praticità ed economia dei processi di lavoro. All’interno dei livelli di cantiere, la presenza abbondante e a volte esclusiva di frammenti di intonaco e la frequenza di simili rinvenimenti sembra suggerire il ricorso ad una tecnica edilizia consolidata, volta al riutilizzo intenzionale di materiale dalle note proprietà drenanti. La portata di tale fenomeno, diffuso nell’intera penisola italica, emerge chiaramente ad Aquileia, dove la presenza di un terreno idrologicamente instabile rende necessario il ricorso ad accorgimenti tecnici volti a contrastare la risalita dell’acqua di falda nelle fasi di ristrutturazione o di ricostruzione degli edifici.

L’archaïsme du vocabulaire désignant les unités foncières (massa, fundus, casale, campus) est en partie culturel; dans le duché de Naples, toutefois, le parcellaire et son organisation semblent avoir peu évolué depuis l’Antiquité. À Naples encore, le régime des terres militaires fait durer jusqu’au Xe siècle une sorte de servitude rurale; d’autre part les defisi doivent à des particuliers les charges normalement dues à l’État.Dans les trois duchés, la grande propriété ducale (publicum) est au départ alimentée par la récupération des patrimoines de l’Église romaine. C’est au milieu du Xe siècle que le publicum commence à passer non seulement à des églises, mais aussi à des familles aristocratiques, dans le cadre de l’émergence de la seigneurie à Gaète, hors de celui-ci à Naples.
Le grand domaine sicilien à l’aube du Moyen Âge
Authors: Prigent Vivien
Published: March 2022

Toute étude de la grande propriété en Sicile au début du Moyen Âge doit être précédée d’une mise en garde. Ce qu’il est possible d’analyser, c’est le fonctionnement des patrimoines de l’Église de Rome. On peut toutefois postuler des liens étroits de forme et de modes d’exploitation entre les grands domaines ecclésiastiques, aristocratiques et publics et admettre que ce que l’on sait du patrimoine de Rome peut s’appliquer à la grande propriété sicilienne en général. La contribution aborde, en outre, deux points complémentaires: l’extension et la forme du grand domaine dans l’île et son mode d’exploitation, le tout en prêtant une attention particulière à l’insertion du grand domaine dans le système fiscal.

Discovering the Emergence of Technical Sociology in Human Capital Systems and Technology-Driven Organizations
Authors: Burrell Darrell Norman , Nobles Calvin
Published: March 2022

In 2019 the global cost of cyber-crime was over 2 trillion dollars. Current research literature outlines that 80-90% of security breaches are due to human-enabled errors in the U.S. and the U.K. Organizations encounter a barrage of cybersecurity threats that prey on the propensity of human error, human inaction, human behavior, and human misbehavior. As a result, there is an emergence of a new area of research development around technical sociology or digital sociology as a domain to explore the human capital perspectives, group dynamics, and social aspects of cybersecurity and technology management. The paper uses a relational content analysis of the literature as the research approach aimed to determine the presence and relationships of common themes and concepts. The results were creation of a concept matrix model of interrelated co-occurring concepts. The approach used was outlined by Krippendorff (1980) who asserts that concepts are "ideational grains;" these grains can be thought of as emblems which develop connotation through their connections to other emblems.

Authors: Misra Rajnish Kumar , Dubey Shalini
Published: March 2022

The current study is based on the preferred attributes of the employer branding, and their influence in the decision-making process of the engineers (Btech graduates) from the different branches. This study attempts to fill the gap by providing a scale on employer branding attributes. To test the scale for employer brand attributes, two studies were conducted. Study 1 applied Exploratory Factor Analysis (EFA) with varimax rotation and Study 2 used second-order Confirmatory Factor Analysis (CFA). The statistics were drawn from 362 students of BTech from four major branches like computer science, electrical, civil, mechanical engineering in Delhi NCR. Results show that the 2 of the employer brands attributes-Job security and fringe benefits have the highest impact on the decision-making process of the students. The current study provides the pragmatic approach from the students of four chosen branches of engineering in selecting the right employer.

Published: March 2022

Dermatoses affecting palms may represent a dermatologic challenge from both the diagnostic, and therapeutic point of view. Patients with supposedly occupational dermatitis can spend months or even years in a frustrating attempt to avoid contact with possible irritants or allergens. To underline the importance of a thorough unbiased analysis of the patient’s history and clinical features, we present the iconic case of a bricklayer affected by a chronic, disabling desquamation of palms which in the end was classified as keratolysis exfoliativa (KE) attributed to ranolazine-intake, an antianginal drug. To the best of our knowledge, this specific adverse effect of druginduced KE of palms has never been reported before in association with ranolazine.
Alveolar Ridge Augmentation Using Autogenous Bone Graft and Platelet-Rich Fibrin to Facilitate Implant Placement
Authors: Paul Nayana , Jyotsna Shivangini , Keshini M. P.
Published: March 2022

The maxillary anterior region is considered to be the esthetic zone of human dentition. Missing teeth in this area leads to severely compromised esthetics and function. Endosseous implants are a viable treatment option in this scenario, but the placement of endosteal implants requires adequate bone volume for successful osseointegration. When the morphology of the bone does not allow proper implant placement, there are various bone augmentation procedures which aid in reconstruction of the residual alveolar ridge for ideal implant placement. The mandibular parasymphysis can act as an excellent source of autogenous bone for the augmentation of alveolar ridge deficiencies. This article describes successful augmentation of the maxillary alveolar ridge using block bone autografts harvested from the mandibular symphysis along with platelet-rich fibrin. At 6 months after surgery, implant was inserted, and after a healing period of 5 months, permanent restoration was placed.

Published: March 2022

Context:

Gingival recession is the most common mucogingival defect and is susceptible to tooth hypersensitivity, root caries, and esthetic problems if left untreated. A lateral pedicle flap is used to cover denuded roots that have adequate donor tissue laterally and adequate vestibular depth. A carefully planned surgery needs proper immobilization of the flap at the recipient site and this can be achieved by proper wound closure technique with appropriate material such as sutures or tissue adhesives.

Aim:

The aim of the present study is to evaluate the clinical outcomes of lateral pedicle flap stabilized with cyanoacrylate tissue adhesive and resorbable sutures.

Materials and Methods:

Twenty-two patients with Miller's class I and class II gingival recession were randomly divided into two groups: lateral pedicle flap stabilized with cyanoacrylate tissue adhesive (test) and lateral pedicle flap stabilized with resorbable sutures (control). Plaque index, gingival index, probing pocket depth, clinical attachment level, recession depth and width, height and thickness of keratinized gingiva were evaluated at baseline and 1st and 3rd month postoperatively. The percentage of root coverage was evaluated at the end of 3rd month postoperatively.

Statistical Analysis Used:

Intergroup comparisons for the clinical attachment level, recession depth, recession width, thickness of keratinized gingiva, and height of keratinized gingiva were made by Mann–Whitney test by analyzing the difference of two time periods. Intragroup comparisons were made by the Kruskal–Wallis test. Mann–Whitney test was used to compare the difference between various time periods within the group for all the selected variables.

Results:

The mean plaque index and gingival index at the 1st and 3rd month were found to be statistically significant and did not present any significant influence over other clinical parameters evaluated. A partial root coverage was observed in both the groups (71.97% for the test group and 61.36% for the control group).

Conclusions:

Cyanoacrylate tissue adhesive is clinically effective in the stabilization of the lateral pedicle flap and can be used as an alternative to resorbable sutures.

Background and Aim:

Tooth-colored restorative materials for the restoration of decayed posterior teeth continue to gain popularity both among dental practitioners and patients. These materials have undergone a number of improvements in recent years to enhance their physical properties and diversify their use as a restorative material relevant to clinical practice. The aim of this study was to evaluate and compare the fracture resistance of two such advanced restorative materials, namely EverX Posterior, a fiber-reinforced composite and Cention N, an alkasite material in a Class I Cavity.

Materials and Methods:

Forty intact, caries-free human maxillary premolar teeth extracted for orthodontic purposes were divided randomly into four groups of 10 teeth each. Group I were unprepared teeth (intact teeth); Group II were unrestored teeth with class I cavity; Group III were teeth restored with fiber-reinforced composite (EverX Posterior); and Group IV were teeth restored using alkasite material (Cention N). Fracture resistance was recorded for all samples using a universal testing machine.

Results:

Higher fracture resistance was recorded in intact teeth group followed by EverX Posterior, Cention N and unrestored teeth, respectively. The teeth restored with EverX Posterior showed higher mean fracture resistance to fractures than those restored with Cention N. Teeth restored with EverX Posterior showed no significant difference in mean fracture resistance from Intact teeth while restored teeth with Cention N and unrestored teeth did.

Conclusion:

Fracture resistance of EverX Posterior was comparable to that of the natural tooth and was higher as compared to Cention N.
