Published: November 2021

Education, undoubtedly, is recognized as determining the social configuration of each state. Most countries of the world are intensively developing and improving the adult education system as an important element of lifelong learning that ensures the development of society. The concept of lifelong education is viewed as a system of the future, which should become the basis for sustainable development, ensuring stability in society, socialization of a person in a changing social environment. Globalization world processes also have a significant impact on education. At the same time, individual education systems should take into account national and cultural characteristics when developing adult education programs so that universalization is combined with existing diversity.
The article analyzes the main directions of adult education such as obtaining a second higher education, business education and training for people of the third age. The specifics of the adult audience, the specifics of the work of teachers, the content of curricula and teaching methods are considered. When writing the article, the experience of working with adults, accumulated at the People's Ukrainian Academy, which is a complex of continuous education, in which the adult education system is logically inscribed, was used and generalized. The need to improve the national system of postgraduate education is expressed. We are talking about creating a unified regulatory framework for adult education, changing sectoral legislation, optimizing the structure of additional postgraduate education.

In this paper analytical study has been made to investigate a hybrid refrigerant consists of different refrigerants with different mixing ratios and find out its effects on the performance of cycle and specify the best refrigerant that gives best performance and least environmental pollution. Firstly the performance of vapor compression refrigeration system has been analyzed with several different pure refrigerants( R11, R12, R13,R22,R23, R32, R41, R115, R116, R124, R125, R134a, R142a, R143a, R152a) by REFPROP software and the values of coefficient of performance (COP) and mass flow rate ( ) and work in compressor (Wc) for each pure refrigerant is calculated and by use other properties for every refrigerant it can determine the best refrigerants to make a new refrigerant that comes from mixing of two or three of pure refrigerants with best performance for example R22 and R134a with mixing ratios (25:75),(50:50),(75:25) respectively Assuming the evaporator temperature is (-10 °C) and the condenser temperature is (35 °C). The main parameters are calculated such as new refrigerant, mass flow rate and work used in compressor for various capacity in (kW). The results showed that the maximum performance recorded with R134a and the minimum value with R115 while the values of performance for their mixtures fluctuated between the maximum and minimum values for the pure refrigerants and the cause of this is due to combination of properties as boiling point temperature and critical temperature, latent heat of vaporization, specific heat of liquid and specific volume of the vapor

There are many ways that community groups do to survive during the pandemic caused by the COVID-19 virus. One way to survive is done by one of the community groups to work together by planting vegetables that can be consumed as daily food ingredients that are filling and nutritious. Over time, the community realized that its strategy to survive could also be materially profitable. Self-harvested vegetable products can be developed into commercial products with a marketing strategy that combines websites and merchandise strategies.
One of the main problems faced by the community is that the community has not adequately understood the strategy for managing and developing a website. However, the community already knows the usefulness of the website and how website development can benefit the community, not only in terms of selling vegetables but also community awareness that is easier to build. Furthermore, with public awareness, more parties will know the products produced by the community. Public awareness will also positively impact the sustainability of the business ecosystem in the community.
The existence of synergies, the right strategy in managing and developing websites, collaboration with the community, and community awareness will have a good impact, especially for the community, not only in growing businesses to survive but also in being an example for others communities.

Authors: EGİL Edibe 
Published: November 2021

Objective: The aim of this study was to evaluate the characteristics of premolar tooth agenesis patterns in Turkish children and confirm a valid cutoff age.
Methods: Included in this study were panoramic radiographs of 3637 Turkish pediatric patients aged 7–12 years (1819 males and 1818 females), whose panoramic radiographs were taken. . The prevalence of premolar hypodontia, sex distribution, distribution of premolar hypodontia in the maxilla and mandible, unilateral/bilateral incidences and cutoff ages were examined in radiographs.
Results: The prevalence rate of agenesis of one or more premolars was 3.1% (n = 111) for both sexes combined, and 1.4% for boys and 1.6% for girls, with no significant difference between the sexes (p = 0.498). No significant difference was observed between younger and older groups at the cutoff ages examined
Conclusion: An early diagnosis of premolar agenesis enables ideal and conservative treatment planning, which may involve less invasive treatment options for patients diagnosed in the early period. For these reasons, the awareness of dentists regarding these treatments should be enhanced. Therefore, there is a need for more studies regarding the prevalence of this condition, which will provide important clinical value in the timely diagnosis of hypodontia.

Enzyme immobilization is an important alternative to stabilize enzyme properties favoring the efficiency of derivatives (enzyme + support/matrix) for different purposes. According to this, the current study aimed to immobilize the Aspergillus fumigatus CAS21 tannase and the use of the derivatives in the treatment of the effluent produced by the tannery industry. The tannase was immobilized on sodium alginate, DEAE-Sephadex, amberlite, and glass pearls as supports. Calcium alginate was the most adequate support for tannase immobilization with 100% yield and 94.3% for both efficiency and activity. The best tannase activity for the calcium alginate derivative was obtained at 50°C–60°C and pH 5.0. Thermal and pH stabilities evaluated for 24 h at 30°C–60°C and pH 4–7, respectively, were improved if compared to the stability of the free enzyme. Considering the reuse of the calcium alginate derivative, 78% of the initial activity was preserved after 10 catalytic cycles, and after the 9-month storage at 4°C, the activity was maintained in 70%. This derivative was applied in a packed bed reactor (PBR) for the treatment of tannin-rich effluents from the tannery industry. The reduction of the tannin content was effective reaching degradation of 74–78% after 48 h of PBR operation. The concentration of total phenolic compounds was also reduced, and the color and clarity of the effluent improved. In conclusion, the calcium alginate derivative is an attractive alternative as biocatalyst for large-scale treatment of the effluents from the tannery industry.

Published: November 2021

Background: The association between abnormal invasive fractional flow reserve (FFR) and the fat attenuation index (FAI) of lesion-specific peri-coronary adipose tissue (PCAT) is unclear.Method: Data of patients who underwent coronary computed tomography angiography (CTA) and subsequent invasive coronary angiography (ICA) and FFR measurement within 1 week were retrospectively included. Lesion-specific FAI (FAIlesion), lesion-free FAI (FAInormal), epicardial adipose tissue (EAT) volume and attenuation was collected, along with stenosis severity and plaque characteristics. Lesions with FFR &lt;0.8 were considered functionally significant. The association between FFR and each parameter was analyzed by logistic regression or receiver operating characteristic curve.Result: A total of 227 patients from seven centers were included. EAT volume or attenuation, traditional risk factors, and FAInormal (with vs. without ischemia: −82 ± 11 HU vs. −81 ± 11 HU, p = 0.65) were not significantly different in patients with or without abnormal FFR. In contrast, lesions causing functional ischemia presented more severe stenosis, greater plaque volume, and higher FAIlesion (with vs. without ischemia: −71 ± 8 HU vs. −76 ± 9 HU, p &lt; 0.01). Additionally, the CTA-assessed stenosis severity (OR 1.06, 95%CI 1.04–1.08, p &lt; 0.01) and FAIlesion (OR 1.08, 95%CI 1.04–1.12, p &lt; 0.01) were determined to be independent factors that could predict ischemia. The combination model of these two CTA parameters exhibited a diagnostic value similar to the invasive coronary angiography (ICA)-assessed stenosis severity (AUC: 0.820 vs. 0.839, p = 0.39).Conclusion: It was FAIlesion, not general EAT parameters, that was independently associated with abnormal FFR and the diagnostic performance of CTA-assessed stenosis severity for functional ischemia was significantly improved in combination with FAIlesion.
On the Origin of ULF Magnetic Waves Before the Taiwan Chi-Chi 1999 Earthquake
Authors: Anagnostopoulos Georgios 
Published: November 2021

The ultra low frequency (ULF) electromagnetic (EM) wave activity usually recorded on Earth’s ground has been found to depend on various types of space weather. In addition ULF waves observed before an earthquake have been hypothesized to be a result of geotectonic processes. In this study we elaborate for the first time the origin of sub-ULF (&lt;1 msec) magnetic field waves before an earthquake (Chi-Chi/Taiwan, 20.9.1999) by comparing simultaneously obtained measurements in the interplanetary space (ACE satellite) and on the Earth’s ground (Taiwan). The most striking result of our data analysis, during a period of 7 weeks, is that the detection of four groups of sub-ULF waves in Taiwan coincide in time with the quasi-periodic detection of two solar wind streams by the satellite ACE with approximately the solar rotation period (∼28 days). The high speed solar wind streams (HSSs) in the interplanetary space were accompanied by sub-ULF Alfvén wave activity, quasi-periodic southward IMF and solar wind density perturbations, which are known as triggering agents of magnetic storm activity. The four HSSs were followed by long lasting decreases in the magnetic field in Taiwan. The whole data set examined in this study strongly suggest that the subULF magnetic field waves observed in Taiwan before the Chi-Chi 1999 earthquake is a normal consequence of the incident of HSSs to the magnetosphere. We provide some observational evidence that the sub-ULF electromagnetic radiation on the Earth was most probably a partner to (not a result of) geotectonic processes preparing the Taiwan 1999 earthquake.

BackgroundThe effect of smoking on coronary artery plaques examined by coronary computed tomography angiography (CCTA) in type 2 diabetes mellitus (DM) patients is not fully understood. This study explored the effect of smoking on coronary artery plaques by comparing the characteristics of plaques between diabetes patients with and without a smoking history and among those with different smoking durations.Materials and MethodsIn total, 1058 DM patients found to have coronary plaques on CCTA were categorized into the smoker (n=448) and nonsmoker groups (n=610). Smokers were stratified by smoking duration [≤20 years (n=115), 20~40 years (n=233) and &gt;40 years (n=100)]. The plaque types, luminal stenosis [obstructive (&lt;50%) or nonobstructive (≥50%) stenosis], segment involvement score (SIS), and segment stenosis score (SSS) of the CCTA data were compared among groups.ResultsCompared to nonsmokers, smokers demonstrated increased odds ratios (ORs) of any noncalcified plaques (OR=1.423; P=0.014), obstructive plaques (OR=1.884; P&lt;0.001), multivessel disease (OR=1.491; P=0.020), SIS≥4 (OR=1.662; P&lt;0.001), and SSS≥7 (OR=1.562; P=0.001). Compared to diabetes patients with a smoking duration ≤20 years, those with a smoking duration of 20~40 years and &gt;40 years had higher OR of any mixed plaques (OR=2.623 and 3.052, respectively; Ps&lt;0.001), obstructive plaques (OR=2.004 and 2.098; P=0.003 and 0.008, respectively), multivessel disease (OR=3.171 and 3.784; P&lt;0.001 and P=0.001, respectively), and SSS≥7 (OR=1.605 and 1.950; P=0.044 and 0.020, respectively). Diabetes with a smoking duration &gt;40 years had a higher OR of SIS≥4 (OR=1.916, P=0.034).ConclusionSmoking is independently associated with the presence of noncalcified, obstructive, and more extensive coronary artery plaques in diabetes patients, and a longer smoking duration is significantly associated with a higher risk of mixed, obstructive, and more extensive plaques.

PurposeTo investigate the prognostic significance of extranodal extension (ENE) in papillary thyroid cancer (PTC).MethodsSeven hundred forty-three PTC patients were enrolled in the study from January 2014 to December 2017. The patients were dichotomized according to the presence of ENE. Logistic analysis was used to compare differences between the two groups. Kaplan–Meier (K-M) curve and propensity score matching (PSM) analyses were used for recurrence-free survival (RFS) comparisons. Cox regression was performed to analyze the effects of ENE on RFS in PTC.ResultsThirty-four patients (4.58%) had ENE. Univariate analysis showed that age, tumor size, extrathyroidal extension, and nodal stage were associated with ENE. Further logistic regression analysis showed that age, extrathyroidal extension, and nodal stage remained statistically significant. Evaluation of K-M curves showed a statistically significant difference between the two groups before and after PSM. Cox regression showed that tumor size and ENE were independent risk factors for RFS.ConclusionsAge ≥55 years, extrathyroidal extension, and lateral cervical lymph node metastasis were identified as independent risk factors for ENE. ENE is an independent prognostic factor in PTC.
A Decade Long Slowdown in Road Crashes and Inherent Consequences Predicted for South Africa
Authors: Machetele Dimakatso , Yessoufou Kowiyou 
Published: November 2021

Globally, there are 1.35 million road fatalities every year, which are estimated to cost governments approximately US$ 518 billion, making road fatalities the eighth leading cause of death across all age groups and the leading cause of death of children and young adults. In South Africa, despite tremendous governmental efforts to curb the soaring trajectory of road crashes, the annual number of road fatalities has increased by 26% in recent years. By fitting a structural equation model (SEM) and a GARCH Model (Generalized Auto-Regressive Conditional Heteroskedasticity) to analyze and predict future trend of road crashes (number of road crashes, number of casualties, number of fatal crashes and number of persons killed) in South Africa, we propose and test a complex metamodel that integrates multiple causality relationships. We show an increasing trend of road crashes over time, a trend that is predictable by number of vehicles in the country, the population of the country and the total distance travelled by vehicles. We further show that death rate linked to road crashes is on average 23.14 deaths per 100,000 persons. Finally, in the next decade, the number of road crashes is predicted to be roughly constant at 617,253 crashes but can reach 1,896,667 crashes in the worst-case scenario. The number of casualties was also predicted to be roughly constant at 93,531 over time, although this number may reach 661,531 in the worst-case scenario. However, although the number of fatal crashes may decrease in the next decade, it is forecasted to reach 11,241 within the next 10 years with the worse scenario estimated at 19,034 within the same period. At the same time, the number of persons killed in fatal crashes is also predicted to be roughly constant at 14,739 but may also reach 172,784 in the worse scenario. Overall, the present study reveals perhaps the positive effects of government initiatives to curb road crashes and their consequences; we call for more stronger actions for a drastic reduction in road accident events in South Africa.
