The analysis of the stress distribution around angulated and parallelly placed implants based on “all on 4 concept” and four implants placed parallel within the interforaminal distance in an edentulous mandible – An in vitro three-dimensional finite element analysis
Authors: Mahantshetty Minal , Thumati Prafulla , Ayinala Mounika 
Published: June 2021

Purpose:
The purpose of the study was to analyze and compare the stress distribution in the so-called All-on-Four concept where two anterior implants were placed parallel to each other and two posterior implants were tilted at 45° angle against the four parallelly placed implants within the interforaminal distance in an edentulous mandible.

Materials and Methods:
The three-dimensional finite element analysis models consisted of cancellous bone surrounded by the cortical bone, four dental implants positioned in two different designs – i.e., four parallelly placed implants (Model 1) and All-on-Four concept (Model 2) with hybrid superstructures comprising of a Hader bar. The vertical (60N, 130N, and 300N) and lateral (20N, 45N, and 100N) loading protocols were considered and von Mises stress values were determined.

Results:
On vertical and lateral loading, lower stress concentrations were observed in the peri-implant region in Model 2. However, there was higher stress concentration noticed on cortical, cancellous bone and bar attachment due to the tilting of implants in every condition.

Conclusion:
Within the limitations of the study, All-on-Four concept is an optimal and viable treatment option if executed accurately as it reduces the cantilever length, reduces stress concentrations in the peri-implant region, and is cost-effective.

Published: June 2021

In this work we present an infection-age-structured mathematical model of AIDS disease dynamics and examine the endemic equilibrium state for stability. An explicit formula for the basic reproduction number R0 was obtained in terms of the demographic and epidemiological parameters of the model. The endemic equilibrium state was found to be locally asymptotically stable under certain conditions. Furthermore, by constructing a suitable Lyapunov functional, the endemic equilibrium state was found to be globally asymptotically stable under certain conditions prescribed on the model parameters.Keywords: Basic reproduction number, HIV/AIDS, Lyapunov functional

Authors: Sen Shubhrakanti , Maity Debmalya , Koley Arnab 
Published: June 2021

Introduction
In 1952 Goldenhar described a case with triad of pre auricular tags, mandibular hypoplasia and ocular (epibulbar) dermoid and described the case as Goldenhar Syndrome.
Case Report
A case of Goldenhar Syndrome without ocular involvement is presented.
Discussion
Goldenhar syndrome is also known as oculoauriculovertebral dysplasia due to presence of additional vertebral anomalies. Exact etiology of this disease is not known. Most of the cases are sporadic, though autosomal recessive/dominant and multifactorial inheritance has also been suggested. Chromosomal analysis shows no abnormalities.
Rare Case of Childhood Lipoblastoma presenting as Tongue Mass
Authors: V Anand , Anand Aishwarya , Ramachandra Manaswini , Janarthanan Sridurga 
Published: June 2021

Introduction
Lipoblastoma is a rare benign tumour arising from embryonic white fat been commonly noted in limbs and trunk, but tongue involvement is rare and has not yet been reported.
Case Report
A child with tongue lipoblastoma is reported, whose imaging reported an encapsulated, well-delineated, fat-containing tumour. Surgical excision was performed with no post-operative morbidities.
Discussion
Lipoblastoma is an uncommon childhood tumour, which rarely affects the tongue. It presents as a progressive painless swelling, rarely causing any symptom. MRI is helpful to assess the precise location and extent of the lesion. Although the ratio of fat to myxocollagenous tissue in the tumour is variable, the diagnosis can be suggested in most cases based on the imaging characteristics. Recommended treatment is complete surgical excision and confirmation of diagnosis by histopathological examination.

Authors: Bag Sreemanti , Rahaman Md. Quaisar , Singh Rajiv , Das Chiranjib , Mukherjee Dwaipayan , Basu Sumit Kumar 
Published: June 2021

Introduction
Noise induced hearing loss has great significance in today’s world as it comes as an occupational health hazard accompanied with other systemic adverse effects like several neuropsychiatric disorders, cardiovascular diseases, or peptic ulcers. It can be prevented by serial follow up with pure tone audiograms and use of noise protectors like ear muffs or ear plugs. This article demonsrates an easy-to-adopt method of preventing noise induced hearing loss in the form of an electronic device named HEAR-O-SCOPE.
Device Design
This device is essentially a decibel meter which senses sound intensities above 85 decibel and equates it with permissible time of exposure for that decibel range and if permissible time of exposure is crossed, sends alarm signals in the form of buzzer and display, giving the user adequate time either to move away from the noisy surrounding or put in noise protectors. This device also has provision for real-time graphical plotting facilities.
Expected Benefits
Expected outcome by using this device in the long run would be early detection and prevention of noise induced hearing loss and other health hazards of noise pollution.
Conclusion
Regular use of HEAR-O-SCOPE is highly recommendable for prevention of Noise Induced Hearing Loss.
Coping with a narcissistic partner during lockdown - A qualitative research
Authors: Costin Alina , Rad Dana 
Published: June 2021

This work is a phenomenological analysis that investigates how the lockdown was perceived by dysfunctional families, namely, narcissistic families. The literature indicates serious disorders in the family life of the narcissist, hostility, tension, conflict, instability (Campbell, Foster, 2002; Kohut, 1972), so, we are interested in describing how narcissistic partners perceive their relationship, and how they describe the period spent during the pandemic restrictions. Two case studies were conducted, which were selected so as to be relevant to the research objectives. We were also interested in the psychological symptoms of the two subjects investigated shortly after the restrictions were lifted. In this regard, the Revised 90 symptom assessment scale (Marian, M.I., 2008) was also applied.
The results of this study confirm the negative effects on mental health that a relationship with a narcissistic partner holds during lockdown and encompasses surprising coping strategies that make living with a narcissistic partner possible.

HISTÓRIA DO MOVIMENTO DE MULHERES CAMPONESAS DE MINAS GERAIS / History and Struggles of Territorialization of the Movement of Peasant Women in Minas Gerais / Historia y luchas de territorialización del movimiento de mujeres campesinas en Minas Gerais
Authors: Rocha Gadelha Renata 
Published: June 2021

O presente artigo busca apresentar a história do Movimento de Mulheres Camponesas no estado de Minas Gerais (MMC MG), como um movimento socioterritorial, destacando seus antecedentes, o início de sua formação e desenvolvimento. Para tanto, utilizou-se a história de vida e a observação participante como meio de coleta de dados. Foram entrevistadas oito camponesas do MMC MG e feitos registros, a partir da participação no Encontro Estadual do MMC MG em 2019, e de visitas ao Sindicato dos(as) Trabalhadores(as) Rurais de Governador Valadares (STR-GV). O MMC MG nasce e se desenvolve no Vale do Rio Doce (VRD), a partir de lutas históricas do campesinato contra a expropriação de suas terras pelos latifundiários. Dessas lutas nasce o STR-GV. É a partir deste sindicato que as mulheres do campo do VRD, na década de 1990, começam a se organizar, articulando-se a movimentos autônomos de mulheres do campo de outros estados e levantando pautas sobre as relações de gênero. Até que, em 2004, o grupo de mulheres organizadas pelo STR-GV participam da criação e passam a integrar o MMC Brasil.Como citar este artigo: GADELHA, Renata Rocha.

Published: June 2021

Abstract. Abundant mining and industrial activities located in the Upper Silesian Coal Basin (USCB) lead to large emissions of the potent greenhouse gas (GHG) methane (CH4). The strong localization of CH4 emitters (mostly confined to known coal mine ventilation shafts) and the large emissions of 448 and 720 kt CH4 yr−1 reported in the European Pollutant Release and Transfer Register (E-PRTR 2017) and the Emissions Database for Global Atmospheric Research (EDGAR v4.3.2), respectively, make the USCB a prime research target for validating and improving CH4 flux estimation techniques. High-precision observations of this GHG were made downwind of local (e.g., single facilities) to regional-scale (e.g., agglomerations) sources in the context of the CoMet 1.0 campaign in early summer 2018. A quantum cascade–interband cascade laser (QCL–ICL)-based spectrometer adapted for airborne research was deployed aboard the German Aerospace Center (DLR) Cessna 208B to sample the planetary boundary layer (PBL) in situ. Regional CH4 emission estimates for the USCB are derived using a model approach including assimilated wind soundings from three ground-based Doppler lidars.
Although retrieving estimates for individual emitters is difficult using only single flights due to sparse data availability, the combination of two flights allows for exploiting different meteorological conditions (analogous to a sparse tomography algorithm) to establish confidence on facility-level estimates. Emission rates from individual sources not only are needed for unambiguous comparisons between bottom-up and top-down inventories but also become indispensable if (independently verifiable) sanctions are to be imposed on individual companies emitting GHGs. An uncertainty analysis is presented for both the regional-scale and facility-level emission estimates.
We find instantaneous coal mine emission estimates of 451/423 ± 77/79 kt CH4 yr−1 for the morning/afternoon flight of 6 June 2018. The derived fuel-exploitation emission rates coincide (±6 %) with annual-average inventorial data from E-PRTR 2017 although they are distinctly lower (−28 %/−32 %) than values reported in EDGAR v4.3.2. Discrepancies in available emission inventories could potentially be narrowed down with sufficient observations using the method described herein to bridge the gap between instantaneous emission estimates and yearly averaged inventories.

This study aims in general to prove and analyze the effect of work involvement, work environment and work morale on teacher job satisfaction at SDN Aeng Beje Kenek. The population of this study were all permanent teachers at SDN Aeng Beje Kenek IV, Kecamatan Bluto recorded in mid-2013 with a total of 80 people. the following results are obtained: (1) The three independent variables, namely work involvement, work environment and morale have a significant positive effect on teacher job satisfaction at SDN Aeng Beje Kenek IV Kecamatan Bluto, thus proving that the three independent variables simultaneously have a significant effect on teacher job satisfaction. (2) Involvement work has a positive effect on teacher job satisfaction. The regression coefficient of 0.3677 shows, if there is an increase in work involvement by 1 point, it will increase teacher job satisfaction by 0.3677 points. Although it has a positive significant effect, job involvement has the smallest effect on teacher job. (3) The work environment in this study has a positive and nutritious effect on teacher job satisfaction. (4) Morale is the most effective and greatest in increasing job satisfaction of a teacher.

Published: June 2021

Issues of applying the asymptotic theory of extreme values to the risks analysis of breaking-out of the largest-area yearly forest fires, were considered. As original material, the paper authors used data on areas of the forest fires occurring in the south of Russia’s Khabarovsk Territory from 1968 to 2017. For each year, the largest-area forest fire was selected from the considered period of time. In all, 50 fires were selected for this period of time (according to quantity of the years in the period). This sample analysis showed that the general population of these fires areas (where the sample was selected) has probability distribution of extreme values of the first type. An analytical expression for the probability distribution function of this general population was received. On the basis of this distribution analysis, a forecast was made concerning risks of the breaking-out and the average recurrence periods of such fires for various values of the burning area. The conducted analysis showed that in 87.5% of cases, in the south of Khabarovsk territory, the largest-area yearly forest fires, with an area of from 50 to 400 km2, will break out with the 1.2 years recurrence interval. In other words, almost every year, with the exception of these rare events when fires with other areas will occur. It was supposed that the probability distribution of extreme values of the first type can be applied not only to the forest area of Russia’s Khabarovsk territory, but also to other zones in the world with large forest areas.
The Influence of Geographic Region on Hip and Knee Arthroplasty Literature From 1988 to 2018
Authors: Sinclair SaTia T. , Emara Ahmed K. , Orr Melissa N. , Klika Alison K. , Piuzzi Nicolas S. 
Published: June 2021

Introduction:
Total joint arthroplasty constitutes a major focus of publications within orthopaedics. Because research expands and investigators from around the world contribute, it is important to understand the dynamics of publication.

Methods:
PubMed was queried for hip and knee arthroplasty-related articles published between 1988 and 2018 within seven orthopaedic journals. A bibliometric analysis was done. The manuscript region of origin was determined by the affiliated country of the last author and used to examine trends in publication.

Results:
A total of 6,160 publications were included. Forty-eight countries from six continents were identified. The quantity of arthroplasty-related publications increased over the study period (n = 246 in 1988 and n = 1,247 in 2018, P < 0.01). Articles were primarily published by North America (51.9%), Europe (32.5%), and Asia (12.4%). Clinical trials accounted for 45.6% of all publications. Articles from Asia received fewer citations than those from North America, Europe, and Oceania (P < 0.001).

Discussion:
The volume of publications was five times greater in 2018 than in 1988, yet international articles constitute a marginal proportion of annual publications. Most of the literature (84.4%) originated from North America and Europe. Balanced publication of international research may favor global communication of findings, increasing the spectrum of available evidence applicable worldwide.

Wat brengt de Wet bescherming erfgenamen tegen schulden? III
De Wet bescherming erfgenamen tegen schulden bestaat bijna vijf jaar. In deze bijdrage is een vervolg op een eerdere bijdrage waarin wordt besproken wat de betekenis is van artikel 4:194a BW in de praktijk. Aan de hand van jurisprudentie wordt bezien hoe succesvol een beroep is op artikel 4:194a BW. Is het daadwerkelijk een vangnet als er sprake is van onverwachte schulden? En wat is een onverwachte schuld eigenlijk?
Aansprakelijkheid, verhaal en draagplicht bij de legitieme portie

Aansprakelijkheid, verhaal en draagplicht bij de legitieme portie
In dit artikel wordt ingegaan op de draagplicht en aansprakelijkheid voor de legitieme portie en de verhaalsmogelijkheden van de legitimaris. De stelling wordt verdedigd dat de aansprakelijkheid van de erfgenamen steeds aansluit bij de evenredigheid van de erfdelen en niet bij de draagplicht. Een andere belangrijke conclusie is dat door de erflater gewijzigde draagplicht nooit verder strekt dan door de erflater verleende draagkracht.
