Az 1939 és 1945 közötti Szlovák Köztársaság államfői tisztsége
Authors: Halász Iván 
Published: May 2022

The paper deals with the constitutional development of the independent Slovakia between 1939 and 1945. It focuses on the position of the president in the context of the Czechoslovak constitutional tradition and authoritarian challanges, which were typical from the end of the 1930’s. The problem of continuity and discontinuity of the state and law is also an important part of the paper. The Slovak constitution was adopted in 1939. The influence of the Southern-European fascist and authoritarian models were strong during the process of constitution-making, but the Czechoslovak constitution of 1920 also had an impact on the legislator. Although the president of Slovakia, Jozef Tiso arrived from the Slovak Catholic and autonomist movement, he became the symbol of pro-Nazi collaboration during the second world war. Tiso had two positions – he was the Slovak president and paralelly the leader of the Hlinka Slovak People Party, which was a dominant political factor in Slovakia. A special act regulated the position of this party and its leader in the constitutional and political system.

Published: May 2022

Background: The aim of this study is to investigate the relative contributions of genetic and environmental factors to variations in dental dimensions in a sample of Turkish twins, and to estimate heritability using dental casts. Study design: The study samples were selected from the twin children between 3–15 years old who referred for their first dental examination. Fifty nine monozygotic and one hundred and forty three dizygotic twin pairs were examined in the study. The alginate impression material used to create the plaster model of maxilla and mandible. Anterior arch width, posterior arch width, arch length and arch circumference were measured on models prepared from measurements taken for both maxilla and mandible with digital caliper. The similarities and differences of the measurements were compared between pairs of twins and zygocytes. Morever, the effects of bad oral habits, bruxism, a result of psychosocial factors on measurements were examined. Statistical analysis was performed using Paired T Test, Wilcoxon Test and Mann Whitney U test.
Results: A total of 404 dental models of 118 (29.2%) monozygotic and 286 (70.8%) dizygotic twins were evaluated. There was no statistical difference between sibling pairs in both monozygotic and dizygotic twins. The measurement similarity between twin siblings differed according to zygosity in all measurements (p&lt;0.05). It has been observed that the finger sucking and mouth breathing affect the dental arch measurements (p&lt;0.05). Conclusion: These results indicate that the differences in dental arch dimensions between monozygotic twin pairs are less than the difference between dizygotic twin pairs.
A 15-year Follow-Up of a Gingivectomy Procedure for Idiopathic Gingival Fibromatosis: A Case Report and Literature Review
Authors: Seki Keisuke , Sato Shuichi 
Published: May 2022

Few long-term reports exist concerning the treatment of idiopathic gingival fibromatosis, which is a rare autosomal dominant genetic disorder associated with non-inflammatory, benign, and chronic fibrous gingival proliferation and which causes serious esthetic problems.
The aim of this study was to report a case of idiopathic gingival fibromatosis treated with a gingivectomy using an inverse bevel flap method and comprehensively followed up for 15 years. A female patient visited a pediatric dentist at 7 years of age; however, a gingivectomy was not performed until the age of 20 years because of an uncertain prognosis. Now, more than 15 years after the gingivectomy, there has been no significant recurrence and the disease is well managed. Treatment by gingivectomy with an inverse bevel flap approach may provide long-term prevention of recurrence of gingival fibromatosis into adulthood. The aim of this study was to obtain new findings on the pathogenesis and prognosis of this rare disease and to review the case reports previously published.

Published: May 2022

To evaluate the changes relating to lower lid position and laxity after cataract surgery.This is prospective study evaluating the lower eyelid position of patients who underwent cataract surgery from June to September 2019. Data collected includes duration of the cataract surgery, the duration of the speculum remaining insitu. Also we included measurements relating to the distraction test, distance of the lower lacrimal punctum from the inner canthus, and margin reflex distance 2 (MRD2) were performed 1 day, 2 weeks & 3 months post surgery. The data was analysed in Microsoft Excel & SPSS software. The study sample comprised 109 cataract patients, all of whom were of South Indian ethnicity, 68 (62.3%) were female with a median age of 74 years, and 67 (61.4%) had surgery in their left eye. The distraction test before surgery was 6.5 ± 0.2 mm, with mild increase after 1 day (7.3 ± 0.3 mm), sustained after 14 days (7.5 ± 0.2 mm), and decreasing after 3 months (7.0 ± 0.5 mm) to a level similar to the initial values (P = 0.02). The lower (lacrimal) lid punctum distance from the inner canthus preoperatively was 6.5 ± 0.3 mm and 7.4 ± 0.2 on day 1 post operatively, 7.2 ± 0.3 two weeks post operatively, 7.0 ± 0.4 mm at 3 months postoperatively (P = 0.04) [Table 1]. The MRD2 preoperatively was 5.0 ± 0.1 mm, 5.4 ± 0.1 mm at 1 days postoperatively, 5.2 ± 0.2 mm at 2 weeks, and 5.4 ± 0.3 mm at 3 months after surgery (P = 0.02). : An increase in lower lid laxity was noted on distraction test & lacrimal lower punctum distance post cataract surgery. Although such a change is expected in the common cataract surgery age group, there seems to be a definite increment noted in the post surgery group.

Primary objective of this study was to identify the disease in active phase, clinically assess it and start medical management. Secondary objective was to analyze whether the objective tools like B-scan and serum levels of IL-6 and HS-CRP aid in the diagnosis of activity in thyroid eye disease. : The aim wasto analyze the correlation of clinical parameters and significance of objective assessment tools in active thyroid eye disease. Clinically diagnosed cases of TED with lid signs, soft tissue changes, restrictive myopathy and bilateral axial proptosis were included in our study. Patients in chronic stable phase were excluded from study. This was a prospective analytical study, conducted from June 2010 till June 2012. Sample size was thirty patients in the age group of 20 to 60 years. Complete ophthalmology workup and objective disease assessment tools including B scan (OTI 1000 with 7.5-10 MHz) was used in our study. All patients underwent CT scan orbit-axial and coronal view. After assessing the severity and stage of the disease, each patient was managed accordingly using different modalities. : Identifying the disease activity early and aggressive management with systemic steroids in moderately active and severe stage has decreased the morbidity associated with the disease. A- scan with orbital B-scan helps in diagnosing the activity in thyroid eye disease. This procedure is very economical with relatively short examination time and no risk of radiation .Follow up of the patients can also be performed easily. IL-6 and HS-CRP was statistically significantly elevated in patients with severe disease when compared to control group. Hence can help in assessing disease activity in patients with severe disease.
Interactive storytelling for the retelling of autobiographical memory in children: A social robotics approach
Authors: Ozaeta Leire , Perez Itsaso , Rekalde Itziar 
Published: May 2022

Memory is one of our fundamental mental functions, which allows us to revive the past in our minds. When memory is mentioned, we usually want to refer to a particular kind of memory, which is autobiographical memory. Access to these memories can be altered by various affective disorders, especially depression. Regarding these techniques, this study aims to focus on storytelling to contribute to the resilience of children using a social robot approach, as they do not perceive the robot as a figure of superiority, but as a peer. The article follows a literature review method. This paper presents a preliminary scenario for child-robot interaction in three phases, using interactive storytelling as a way to review the children's past experiences. To help those people, particularly children who have faced trauma, to remember the past in a structured and positive way, life review techniques have been developed.
Keywords: Autobiographical; memory; robotics; storytelling.
Late Cretaceous Granitoids along the Northern Kuching Zone: Implications for the Paleo-Pacific Subduction in Borneo

Published: May 2022

Abstract
The EW-trending Kuching zone in Borneo is a target region for exploring the southern continuation of Paleo-Pacific subduction from South China, Vietnam to SE Asia. Previous studies mainly focused on mafic igneous rocks, and poor attention has been paid to the contemporaneous granitoids in this zone. This study presented detailed zircon U-Pb geochronology and Lu-Hf isotope and whole-rock geochemistry analyses for late Cretaceous granitoids (granodiorites and granites) in the northern Kuching zone. These granitoids are dated at ~77.5-83.6 Ma with younger ages than the igneous rocks in the southern Kuching zone (~130-144 Ma). The granitoids have variable SiO2 (64.86-77.37 wt.%) and A/CNK (0.7-1.5) and are strongly enriched in LILE and depleted in HFSE with significant Ba, Nb, Sr, and Ti negative anomalies. They have variable (87Sr/86Sr)i (from 0.70656 to 0.71208), εNd(t) (from -4.4 to +0.9), and zircon εHf(t) (from -1.2 to +12.4) with high (206Pb/204Pb)i ratio of 18.78-19.74, suggesting derivation from a hybrid source involving meta-sedimentary and meta-igneous rocks. Combined with previously-published data, two episodes of Cretaceous (~77-98 Ma and ~130-144 Ma) magmatic activities are identified in the Kuching zone, showing a younging age trend from south to north. These episodes of Cretaceous igneous rocks and their spatial distribution in the Kuching zone can be totally comparable to those in South China and Vietnam. Thus, the Kuching zone was likely a part of the Paleo-Pacific subduction system during the Cretaceous, northerly linking to Vietnam and South China.
Theoretical Research in Laboratory and Field Trial of Micro-Nano-Oil Displacement System Conformance Control Technology
Authors: Sun Zhe , Wang Xiujun 
Published: May 2022

Abstract
In recent years, a series of field tests of a new micro-nano-oil displacement system (MNS) conformance control technology have been carried out in different oilfields, which can increase oil production and reduce water cut obviously. However, compared with its field application, the research on its performance evaluation and oil displacement mechanism is still in the initial stage. And it is urgent to carry out relevant research work. Therefore, this paper made a profound study on its physicochemical properties, reservoir adaptability, transport and deep fluid diversion ability, and oil displacement mechanism. Results show that MNS with a series of particle sizes in different sizes (from nanometer to micrometer) can be obtained. And it has good expansion ability. Through reservoir adaptability evaluation, the matching relationship between the size distributions of MNS particles and pore throat is given, which has important guiding significance for MNS particle size selection for target reservoir before field trial. Furthermore, MNS has strong transport ability. When migrating in the porous media, it shows the motion feature of “trapping, deformation, migration, retrapping, redeformation, and remigration,” which can obtain better oil incremental effect than traditional polymer flooding. Under the condition of the same agent type, composition, and slug size, the oil recovery rate can be further enhanced by 6.96%. In addition, MNS conformance control technology has obtained good technical and economic effect in the 8 oilfields, with the lowest input-output ratio of 1.67 and the highest of 14.37. The reason why MNS have the above-mentioned good performances depends on its advanced mechanism: the unique particle phase separation phenomenon. When transporting in porous media, MNS particles gather in the larger pore to form bridge blocking, and its carrier fluid displaces oil in the small pore. Working in cooperation, MNS can realize deep fluid diversion and expand macroscopic and microscopic swept volume.

Abstract
Background: Fibrin(ogen) amyloid microclots and platelet hyperactivation previously reported as a novel finding in South African patients with the coronavirus 2019 disease (COVID-19) and Long COVID/Post-Acute Sequelae of COVID-19 (PASC), might form a suitable set of foci for the clinical treatment of the symptoms of long COVID/PASC. A Long COVID/PASC Registry was subsequently established as an online platform where patients can report Long COVID/PASC symptoms and previous comorbidities. Methods: In this study, we report on the comorbidities and persistent symptoms, using data obtained from 845 South African Long COVID/PASC patients. By using a previously published scoring system for fibrin amyloid microclots and platelet pathology, we also analysed blood samples from 80 patients, and report the presence of significant fibrin amyloid microclots and platelet pathology in all cases. Results: Hypertension, high cholesterol levels (dyslipidaemia), cardiovascular disease and type 2 diabetes mellitus (T2DM) were found to be the most important comorbidities. The gender balance (70% female) and the most commonly reported Long COVID/PASC symptoms (fatigue, brain fog, loss of concentration and forgetfulness, shortness of breath, as well as joint and muscle pains) were comparable to those reported elsewhere. These findings confirmed that our sample was not atypical. Microclot and platelet pathologies were associated with Long COVID/PASC symptoms that persisted after the recovery from acute COVID-19. Conclusions: Fibrin amyloid microclots that block capillaries and inhibit the transport of O2 to tissues, accompanied by platelet hyperactivation, provide a ready explanation for the symptoms of Long COVID/PASC. Removal and reversal of these underlying endotheliopathies provide an important treatment option that urgently warrants controlled clinical studies to determine efficacy in patients with a diversity of comorbidities impacting on SARS-CoV-2 infection and COVID-19 severity. We suggest that our platelet and clotting grading system provides a simple and cost-effective diagnostic method for early detection of long COVID/PASC as a major determinant of effective treatment regimens, including those focusing on reducing clot burden and platelet hyperactivation.

Published: May 2022

Abstract
Nanocellulose, a unique and promising nanosized cellulose fibers extracted from renewable biomass, has gained much attention from both the scientific and industrial communities due to abundant resources, good mechanical properties, distinct surface chemistry, and biological properties. Thus, nanocellulose is a appealing biomaterial for exciting applications, including super absorbent materials, electronic components, energy devices, and reinforcements. Cellulose nanocrystal (CNC), cellulose nanofibril (CNF), and bacterial cellulose (BC) are the three kinds of typical nanocellulose from different routes, thus the comprehensive comparison of CNC, CNF, and BC is highly desirable. In order to better understand their special characteristics, we have described detailedly of CNC, CNF (including TEMPO oxidized CNF and mechanically ground CNF), and BC in current work. Meanwhile, this study systematically compared their preparation method, morphologies, chemical structure, surface chemistry, degree of polymerization, thermal behavior, mechanical property, and so on, all these are good for understanding the structure-property-function relationships of nanocellulose. The systematic comparative study can help to develop the criteria for selecting proper nanocellulose as biobased nanomaterials for high value-added applications. We believe that these detailed information presented here have the potential to achieve true sustainable, economic, and tailored production of nanocellulose at large scale, thus contributing to advancement of biobased nanocellulose.
Regional Industrial Growth and Biopharma Patent Networks: Empirical Insights from the UK
Authors: Gao Yuan , Zhu Zhen 
Published: May 2022

Abstract
The COVID-19 pandemic has once again brought the significance of biopharmaceutical and medical technology sectors to the spotlight. Seeing that some of the most critical medical breakthroughs such as the speedy mRNA vaccine development were results of cross-border patenting collaboration, we have proposed in a previous work a new method to identify the cross-border collaborative regional centres in the patent networks, using on a clustering comparison approach based on adjusted mutual information (AMI). In this paper, we focus on the UK industrial landscape. We use the UK bioscience and health technology sector statistics from 2015 to 2020 and look into the regional growth of each postcode area. We compare the top growth regions with the cross-border collaborative centers identified using AMI comparison at the postcode area level, and find that both long-term and short-term AMI gains show an increase in the correlation with regional annual growth rates of firm numbers in the studies sectors from 2016 to 2020, and the increase is more consistent with the short-term AMI gain. Areas more central in the long-term cross-regional R&D collaboration tend to have more developed industrial settings with higher business numbers and, potentially more employment and turnover in the field.
New Formulas for the Trigonometry of Isosceles Triangles
Authors: King Noah 
Published: May 2022

Abstract
This paper discusses a new formula to solve for the angle of isosceles triangles given proportion of differentiated unequivalent edge length versus the always-equivalent edges. The equation is equal to the arcsine of (X/2) multiplied by two. This formula is to be called ‘isn^-1(x)’, short for inverse isosceles sine equivalent. Also discussed is the non-inverse ‘isn(x)’ which is the cyclic function which is determined to correspond as the equivalent of the classic sine formula to isosceles triangles. The formula set is clearly superior and powerful at calculating the angle and measure of any given obtuse or acute triangle of an unclassified type, as well as unifying a simplest-fit formula across all types of triangle. Also discussed are two transform approximation formulas, which help to analyze graphs and samples.

Abstract
Objective
Describe the vaccination status, treatment, and outcomes of hospitalized, symptomatic pregnant women with Coronavirus Disease 2019 (COVID-19) and estimate whether treatment differs by pregnancy status among treatment-eligible (i.e., requiring supplemental oxygen per National Institutes of Health guidelines) women.
Methods
During January–November 2021, the COVID-19-Associated Hospitalization Surveillance Network completed medical chart abstraction for a probability sample of 2,715 hospitalized women aged 15–49 years with laboratory-confirmed SARS-CoV-2 infection. Of these, 1,950 women had symptoms of COVID-19 upon admission; 336 were pregnant. We calculated weighted prevalence estimates of demographic and clinical characteristics, vaccination status, and outcomes among pregnant women with symptoms of COVID-19 upon admission. We used propensity score matching to estimate prevalence ratios (PR), and 95% confidence intervals (CI) of treatment-eligible patients who received remdesivir or systemic steroids by pregnancy status.
Results
Among 336 hospitalized pregnant women with symptomatic COVID-19, 39.6% were non-Hispanic Black, 24.8% were Hispanic or Latino, and 61.9% were aged 25–34 years. Among those with known COVID-19 vaccination status, 92.9% were unvaccinated. One-third (32.7%) were treatment-eligible. Among treatment-eligible pregnant women, 74.1% received systemic steroids and 61.4% received remdesivir. Among those that were no longer pregnant at discharge (n = 180), 5.4% had spontaneous abortions and 3.5% had stillbirths. Of the 159 live births, 29.0% were pre-term. Among a propensity score-matched cohort of treatment-eligible hospitalized women of reproductive age, pregnant women were less likely than non-pregnant women to receive remdesivir (PR 0.82, 95% CI 0.69–0.97) and systemic steroids (PR 0.80, 95% CI 0.73–0.87).
Conclusion
Most hospitalized pregnant patients with symptomatic COVID-19 were unvaccinated. Hospitalized pregnant patients were less likely to receive recommended remdesivir and systemic steroids compared to similar hospitalized non-pregnant women. Our results underscore the need to identify opportunities for improving COVID-19 vaccination, implementation of treatment of pregnant women, and the inclusion of pregnant women in clinical trials.
