Published: October 2022

The aim of the study is to compare the apical microleakage of two Bioceramic sealers Ceraseal, MTA Fillapex and an Epoxy resin sealer (AH Plus) with two different obturation techniques single cone and thermoplastic obturation techniques using dye extraction method. 80 mandibular single rooted premolars were decoronated, & biomechanically prepared. The samples were randomly divided into eight groups with ten samples (n=10). Group (A1) contained roots samples obturated with Ceraseal sealer and a single cone Gutta percha. Group (A2) constituted samples obturated using Ceraseal sealer and thermoplastic obturation. Group (B1) samples were obturated with MTA Fillapex sealer with a single cone. Group (B2) contained roots which were obturated using MTA Fillapex sealer with a thermoplastic obturation. Group (C1) contained roots samples obturated using AH Plus sealer with a single cone. Group (C2) samples were obturated using AH Plus sealer with thermoplastic obturation. Group D and Group E served as positive and negative control. Apical leakage was assessed using dye extraction method. Warm or cold obtuartion technique using sealers with different composition does not totally eliminate apical microleakage.
Comparison of fracture resistance of mandibular central incisors following the use of two different spreaders during lateral condensation obturation technique- An in vitro study
Authors: Gupta Khushboo 
Published: October 2022

The lateral condensation is the most commonly practiced obturation technique during root canal treatment. In this method, the use of spreaders is instrumental in acheiving 3-D obturation. These spreaders can create an unnecessary stress during use, by means of wedging force that might lead to vertical root fracture, resulting in failure of root canal treatment.Sixty extracted mandibular central incisors were taken. All teeth were sectioned 2 mm coronal to CEJ and were wrapped in aluminium foil. The specimens were embedded in acrylic mould. Aluminium foil was scratched and the created space was filled with light body silicone impression material. Then, after working length determination, apical preparation was done with 40 no. K- file. Rest of the canal was prepared using step back technique. The samples were then randomly divided into 3 groups of 20 samples each. Group 1 No obturation (control group). Group 2 Obturation done using stainless steel finger spreaders. Group 3 Obturation done using nickel titanium finger spreaders. After the obturation, all samples were subjected to fracture using metal indenter on the universal testing machine. The load at which fracture occur was recorded. Data thus obtained was subjected to statistical analysis using ANOVA and TUKEY test.The mean fracture resistance of group 1 was highest followed by group 3 (NiTi spreader) and least in group 2 (SS spreader). NITI or SS spreaders can affect the fracture resistance of teeth during lateral condensation obturation technique.
The Philosophy of Generation of 1960s as a Social Phenomenon
Authors: Guseinov A.A. 
Published: October 2022

In its main part, the article is devoted to the Soviet philosophy of generation of the 1960s. It begins with a preface, which regards belonging to a generation as a sign of fate, and ends with an afterword, according to which the past is not judged. Belonging to a generation is the seal of time on individual destinies. The author belongs to the generation of Soviet philosophers who directly followed the sixties and got lost in their shadow. It shows how they are seen from this close distance. They personified the renewal of philosophy in the Soviet Union in the second half of the 20th century. It is shown that it began at the Faculty of Philosophy of Moscow University in the form of opposition of young researchers to the dogmatically minded professors, that its origins were two outstanding thinkers – Evald Ilyenkov and Alexander Zinoviev, who set the speculative-dialectical and scientific-analytical lines of development of philosophical research with their work. The philosophy of the sixties was humanistically oriented and emerged as a decisive break with the philosophical dogmatism of the 1930s and 1940s; it was the theoretical justification for the process of de-Stalinization that had begun in the country. It was represented by many original theories of thought and action, inspired by the ideas of the sovereignty of the human mind and the individually responsible existence of the individual. The philosophy of the generation of the 1960s remained loyal to the teachings of Marx and the socialist ideal, existed, as it were, in parallel with official orthodoxy, with its internal rejection.
The Philosophers of the 1960s: Post-War Brotherhood of Fathers and Sons
Authors: Solov'jov E.J. 
Published: October 2022

The article attempts a socio-genealogical analysis of the “philosophers of the 1960s”. This is how the literature of recent years refers to the generation of young philosophers who in the 1950s and 1960s opposed themselves to the dominant dogma and prepared the de-Stalinization of public consciousness. In the foreground are young front-line intellectuals enlightened by the war. The author talks about their hopes, which already foreshadowed the “thaw”; about stoic morality and courageous protest behavior in scientific and ideological discussions of the post-war period. Further, the life of the “younger growth” of the future “philosophers of the sixties” - schoolchildren of the late 40s – early 50s is covered in detail. Particular attention is paid to the understanding of education as a sacred duty to warrior fathers and a kind of youth cult of knowledge and science. The beginning of a long-term informal community of Soviet “philosophers of the sixties” was laid by a discussion about philosophy, which took place at the Faculty of Philosophy of Moscow State University in 1954. The author sees in it a bold and quite successful attempt at the philosophical reformation of Marxism. Two years before the 20th Congress of the CPSU, which called for the restoration of Lenin&#x27;s norms of life, the “philosophers of the sixties” called for a return to Marx&#x27;s norms of thinking. The last section of the article talks about the original concepts of thinking and consciousness that appeared in Soviet philosophy in the 60s and early 70s and sometimes had a neo-Marxist vision.

La presente investigación tuvo como objetivo conocer la percepción de los alumnos de la Licenciatura en Administración y Gestión Empresarial de la Universidad Politécnica del Estado de Morelos respecto al modelo híbrido que se implementó a partir del mes de septiembre del 2021 para el proceso enseñanza – aprendizaje. De esta forma, se pretendió determinar los elementos que favorecieron el aprendizaje en la modalidad híbrida de los alumnos antes mencionados.
Este escrito detalla en la Introducción, el problema de investigación, así como el impacto del estudio realizado. Posteriormente, en el Marco Teórico, se ofrece una base conceptual basada en referencias bibliográficas de actualidad relacionadas con los temas tratados (COVID-19, estrategias de enseñanza aprendizaje durante la pandemia, modelo híbrido). Antes de desarrollar el apartado de la Metodología, se describe el problema de la investigación para posteriormente describir, los procedimientos, el enfoque y método de investigación. Igualmente, se describe el instrumento utilizado para la recolección de datos y las variables que lo conforman. Por último, se mostraron los resultados, conclusiones y propuestas hechas por las autoras.
El problema de investigación surge dado que se desconocía cuál sería la experiencia de aprendizaje en los estudiantes, quienes serían el objeto de estudio, con esta modificación. Puede pensarse que existen elementos que favorecieron, sin embargo, no se tenía evidencia, porque este modelo híbrido no había sido implementado anteriormente.
Así fue como se desarrolló un instrumento integrado por 23 reactivos que tuvieron como fin evaluar las siguientes variables: situación personal y familiar, uso de tecnología, experiencia de aprendizaje y socialización y convivencia. Este instrumento se aplicó en la Universidad Politécnica del Estado de Morelos, a los estudiantes de la Licenciatura en Administración y Gestión Empresarial (LAE) de los cuatrimestres activos del período mayo-agosto 2022.
Como resultado del estudio, se pudo comprobar que el modelo híbrido implementado en los períodos cuatrimestrales de septiembre-diciembre 2021 y enero-abril 2022, contribuyó a mejorar la experiencia de aprendizaje y las habilidades adquiridas durante el modelo en línea de los estudiantes de la Lic. en Administración y Gestión Empresarial de la Universidad Politécnica del Estado de Morelos.

Authors: Barr Meaghan L. , Jain Nirbhay S. , Ghareeb Paul A. , Benhaim Prosper 
Published: October 2022

Case:
In this report, we describe a 41-year-old woman with symptoms concerning for acute carpal tunnel syndrome. Operative exploration resulted in resection of an aneurysmal, thrombosed, persistent median artery seen on preoperative imaging and full recovery by the patient.

Conclusion:
A persistent median artery is an uncommon congenital hand condition resulting from the failure of the median artery to regress, which can then travel through the carpal tunnel and be associated with a bifid median nerve, irritation of the nerve, and need for surgical exploration if it thromboses, which is rare. This should be considered in patients with acute median nerve compression, without other etiologies.

Background:
The aim of this study was to compare the efficacy of 3 methods of intraoperative analgesic cocktail injection during total knee arthroplasty (TKA)—intra-articular (IA), periarticular (PA), and combined intra-articular and periarticular (IA+PA)—on controlling early postoperative pain.

Methods:
This was a prospective double-blinded parallel randomized clinical trial. A total of 153 patients scheduled for TKA were allocated to IA, PA, or IA+PA (51 patients each) by block randomization. The primary outcome was morphine consumption. Secondary outcomes were visual analogue scale (VAS) pain, knee flexion, straight leg raising, Knee Society Score (KSS), and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC).

Results:
The morphine consumption was lowest in the PA group (median = 0, interquartile range [IQR] = 5) and highest in the IA group (median = 10, IQR = 5). The PA group had significantly lower VAS pain at rest than either IA (mean difference = −0.70; 95% confidence interval [CI] = −0.93 to −0.46; p < 0.001) or PA+IA (mean difference = −0.41; 95% CI = −0.65 to −0.18; p < 0.001). The PA group had also lower VAS pain during activity compared with IA (mean difference = −0.63; 95% CI = −0.85 to −0.40; p < 0.001) and IA+PA (mean difference = −0.38; 95% CI = −0.61 to −0.16; p < 0.001). The PA group had significantly greater active knee flexion compared with IA (mean difference = 9.68°; 95% CI = 5.50° to 13.86°; p < 0.001) and IA+PA (mean difference = 5.13°; 95% CI = 0.95° to 9.31°; p = 0.010). Passive knee flexion was greater for PA than IA (mean difference = 7.85°; 95% CI = 4.25° to 11.44°; p < 0.001). Other outcome variables were not significantly different among the 3 groups. The only complications were wound drainage (1 each in the IA and IA+PA groups) and deep venous thrombosis (1 in the IA group).

Conclusions:
PA was associated with less early postoperative pain and greater active knee flexion compared with the other 2 analgesic methods.

Abstract

Background: Globally, obstetric violence (OV) is considered a serious public health problem, linked to childbirth experience, and satisfaction with maternity healthcare perception.
Objectives: The study aimed to assess for OV existence among sample of pregnant Jordanian women and for OV domains risk factors.
Methodology: A case control study was conducted in public and private settings, 259 recently delivered mothers were the participants. A designated questionnaire including the demographic variables and OV domains. The responses to the questionnaire’s questions were analysed statistically.
Results: Settings were significantly associated with the educational status. OV domains including delivery supervision, overall satisfaction, occupation and the family monthly income were significantly associated in the private settings, in the private settings, respect feeling, discrimination feeling, the delivery provision update and performing episiotomy consent were higher versus the public ones, while, it was lesser for physical abuse. There was a significant association between delivery in a private room and the lack of physical abuse. In the public settings, medications information was lesser compared to the private ones, addionally, there is significant association between performing episiotomy, physical abuse by staff and the delivery in shared rooms in the private settings.
Conclusion: This study clarified obstetric violence prevalence during childbirth in public and private setting. in Jordan with less susceptibility in the private settings. The educational status, low monthly family income, occupation are risk factors for OV, also, the participants were subjected to some features of disrespect and abuse like obtaining consent for episiotomy performance, delivery provision updates, care perception based on payment ability and medication information.

Abstract

Background: Pre-exposure prophylaxis (PrEP) effectively prevents HIV acquisition but may be associated with an elevated risk of other sexually transmitted infections (STIs) due to increased condomless anal intercourse (CAI) among sexual and gender minorities (SGM). We estimated the odds of self-reported CAI, concurrent sexual relationships with two or more male partners (concurrency), and sexually transmitted Infections (STIs)among SGM in Nigeria before and during the use of PrEP.
Methods: This was anopen-label prospective study of SGM seen over four clinical visits between April 2018 and May 2019 as a nested study of the ongoing TRUST cohort study in Abuja, Nigeria. We identified participants who had been in the TRUST study on or before Feb 15, 2016, thereby providing at least 26 months of pre-PrEP initiation data for a “pre PrEP - PrEP” intervention analysis with participants serving as self-controls. Using conditional logistic regression, we estimated the odds ratio (ORs) and 95% confidence intervals (CIs) of PCR-diagnosed bacterial STIs (rectal Chlamydia trachomatis, rectal Neisseria gonorrhea, urethral Chlamydia trachomatis, and urethral Neisseria gonorrhea) and self-reported behavioral outcomes (CAI and concurrency).
Results: Of the 400 SGM who initiated PrEP in this study, 206, with a median age of 24 years (interquartile range: 22-27) were eligible for these analyses. Compared with the pre-PrEP period, participants in the PrEP period had higher unadjusted odds of rectal gonorrhea (OR: 3.53, 95% CI: 1.10, 11.35) and decreased odds of self-reported CAI (OR: 0.57, 95% CI: 0.37, 0.87). There were no significant associations with other STIs or concurrency. In the adjusted analysis, after controlling for alcohol use in the past month, participants in the PrEP period had decreased odds of CAI (adjusted OR: 0.49, 95% CI: 0.28, 0.84).
Conclusion: PrEP use was not associated with behavioral risk compensation among SGM in our study. However, there is a need for increased surveillance for STI screening and diagnosis among SGM using PrEP. These measures should complement ongoing behavioral risk-reduction counselling, emphasizing consistent condom use to prevent bacterial STIs while on PrEP.
Joint Iterative Detection and Decoding for Polar-Coded MIMO-IDMA Systems

Published: October 2022

Abstract
Non orthogonal multiple access (NOMA) was one of the key potential physicallayer technologies considered for the fifth generation (5G) wireless communication systems. Interleave division multiple access (IDMA), which uses packet level interleavers to distinguish multiple access users, is a promising NOMA scheme. Recently, polar codes have received extensive attention as a capacity approaching code and have already been adopted as the channel coding technique for the physical-layer control channel of 5G New Radio (NR). On the other hand, Multiple-Input Multiple Output (MIMO) has been one of the key enabling technologies in the recent standardized wireless communication systems. The performance benefits of both IDMA and MIMO can be obtained by combining two technologies. In this paper, a polar-coded MIMO-IDMA uplink system model with QPSK modulation is proposed. Moreover, we propose an joint iterative detection and decoding (JIDD) receiver. In the proposed JIDD receiver, at each iteration, likelihood messages are exchanged between the soft multiuser MIMO detector and belief propagation (BP) polar decoders. The numerical results confirm that polar coding offers significant performance improvement over the uncoded MIMOIDMA system. Furthermore, considerably improved error performance can be obtained by using the proposed JIDD receiver scheme over single-pass (non-iterative) multiuser MIMO detection and decoding.

Abstract
Ionic thermoelectrics (i-TE) possesses great potential in powering distributed electronics, because it can generate thermopower up to tens of millivolts per Kelvin 1, 2. However, due to the fact that ions cannot enter external circuit, the utilization of i-TE is currently based on capacitive charge/discharge 3, which results in discontinuous working mode and low energy density 4. Here, we introduce an ion-electron thermoelectric synergistic (IETS) effect by utilizing an ion-electron conductor. Electrons/holes can drift under the electric field generated by thermodiffusion of ions, thus converting the ionic current into electrical current that can pass through the external circuit. Due to the IETS effect, i-TE is able to operate continuously for over 3000 min. Moreover, our i-TE exhibits a thermopower of 32.7 mV K-1 and an energy density of 553.9 J m-2, which is more than 6.9 times of the best reported value. Consequently, direct powering of electronics by i-TE is realized. This work provides a new strategy for the design of high-performance i-TE materials.
