Introduction. Odontopreparation is an integral step in orthopedic dental treatment with non-removable orthopedic constructions. Correctly performed this stage in the treatment of artificial crowns is a guarantee of the quality of orthopedic treatment. Ensuring a stable geometry of the stump, a ledge of sufficient width on the abutment and the absence of defects on its surface, the clarity of the preparation margin and the correct ratio with marginal periodontal tissues are the most significant criteria for the quality of the intervention. In addition, the quality of the odontopreparation of the orthopedic profile is influenced by the clarity of adherence to the selected algorithm of preparation and the properties of the rotary tool used. The available literature data indicate numerous deviations in the practice of dentistry from the recommended methodology of odontopreparation, which can be explained by the relatively high frequency of complications of treatment with non-removable orthopedic structures. The purpose of the article is to analyze the key factors affecting the quality of fixation and the durability of the functioning of artificial crowns, based on an assessment of the basic principles of odontopreparation for this type of orthopedic structures and the reaction of periodontal tissues based on an analytical review of the literature. Materials and methods. The article presents the data of the literature review on the main factors that are of great importance as the fixation and durability of the functioning of artificial crowns on the stumps of dissected teeth while observing step-by-step odontopreparation algorithms with provision of proper functional and desired aesthetic requirements without negative influence on the condition of the tissue. Conclusion. Based on the analysis of literary sources, it was concluded that the key factors affecting the quality of the formation of the tooth stump to be prosthetized, subject to step-by-step odontoperational algorithms with the creation of conditions for high-quality fixation and durability of the functioning of the artificial crown, ensuring the proper functional and desired aesthetic requirements without negative impact periodontal tissues can significantly reduce the manifestation of unwanted complications, and as a result to increase the effectiveness of prosthetics with artificial crowns.

Smart environments and the use of interactive technology has the potential to improve the quality of life for the senior community as well as to support the connections among the senior community and the world outside their community. In addition to the increasing number of studies in the field of aging and technologies, research is needed to understand the practical issues of user focus, adoption, and engagement for older adults to accept interactive technologies in their lives. In this study, we use two commercial technological interventions (uDraw and GrandPad) to understand technology-related perceptions and behaviors of older adults. We present five case studies that emerge from empirical observations of initial engagement with technology through research methods such as focus group discussions, in-depth interviews, observations, and diary studies. The contributions of this study are identification of the key factors that influence the initial engagement with interactive technology for older adults.

Abstract Background Unaddressed high distress leads to noncompliance with treatment, negatively affects quality of life, and may also have a negative impact on the prognosis of cancer patients. Patients with brain tumors have higher levels of distress than the general population and hence we hypothesize that even routine visits during adjuvant treatment or follow-up are likely to be stressful. This analysis was performed to identify the incidence of distress and factors affecting it. Methods This was an audit of 84 consecutive patients seen in an adult neuro-medical oncology outpatient department who were either receiving adjuvant chemotherapy or were on follow-up. Distress screening with the National Comprehensive Cancer Network (NCCN) distress thermometer was performed. Patients in whom distress was scored as 4 or above were considered as having high distress. Descriptive statistics and logistic regression analysis were performed to identify factors affecting distress. Results The median age of the cohort was 40 years (interquartile range, 28.3 to 50 years). Actionable distress defined as a distress score of 4 or more was seen in 52 patients (61.9%, 95% CI 51.2% to 71.5%). Presence of physical deficit (odds ratio [OR] = 3.412, P = .020) and treatment under the private category (OR = 5.273, P = .003) had higher odds of having high distress. Conclusion A high proportion of brain tumor patients either on adjuvant chemotherapy or on follow-up have high distress levels that need to be addressed even during follow-up.

Equiaxed Grains

Grain refinement and hot tearing are important key factors affecting the quality of castings. There have been substantial advances in the understanding of both of these phenomena over the last two decades. The paper discusses strategies for obtaining the lowest cost grain refiner addition and provides an explanation for how the refinement of equiaxed grains leads to a reduction in hot tear susceptibility. However, it also provides a warning that adding more grain refiner may not be better for reducing hot tear susceptibility. Alloy factors affecting hot tearing are also discussed. Finally, a list of six key considerations is provided to help casthouse and foundry engineers when trying to optimise grain refinement and reduce hot tearing.

The article provides an analysis of key trends in the international market, using the example of the countries of Northeast Asia. In 2019, the world coal market amounted to 1,424.5 million tons, of which 78.1% are energy grades to produce electricity and heat, and 21.9% are in metallurgy, the reserves of which are significantly less. The import coal market of the countries of Northeast Asia in 2019 was already 680 million tons, covering 48% of the entire world coal market. The paper provides an overview of the key importers and exporters of coal in the world, the quantitative and qualitative characteristics of the supplied raw materials, and analyzes the key factors affecting the pricing of coal. In the conclusions, the main trends in the international coal market of the countries of Northeast Asia are presented, including "geographical" — the shift of the center of world trade from Europe to Asia, and "types and quality of imported coal" — an increase in the share of high-quality premium energy and coking (metallurgical). Trends can be clearly seen in the countries of Northeast Asia, which actively use coal, and are making efforts to decarbonize their national economies, while intensifying inter-fuel competition with other primary energy sources.

Abstract The gelation process of poly(vinyl chloride) (PVC) plastisol is very important to ensure the quality of the product and is affected by the type of resins, plasticizers, and other additives. In this study, the gelation process of the as-prepared PVC plastisol was characterized by measuring the evolution of vibrational viscosity with temperature or time using a vibrational viscometer. Furthermore, the effect of some commercial resins with different particulate morphologies on the gelation process was investigated by synchronously combining scanning election microscopy and laser particle size analyses. The results of this study proved that the particle size distribution and the aggregation degree of the secondary particles of a resin are the key factors affecting the gelation process. For the resin with bimodal particle size distribution, the closer the aggregation of the secondary particles, the slower the gel speed; however, an opposite behavior was observed for the resins with unimodal particle size distribution.

Objectives: To determine the association between types of malocclusion and quality of life in children between 8-10 years of age and establish correlations between the severity of the malocclusion and particular bio-psychosocial variables. Study design: The sample was made up of 102 schoolchildren aged 8-10 years. Clinical exams were performed using the criteria of the Dental Aesthetic Index (DAI) to determine the presence and severity of malocclusions. The impact on quality of life was assessed using the Child Perceptions Questionnaire (CPQ8-10). Statistical analysis involved the chi-square test, Fisher's exact test and Spearman's correlation analysis. Results: Malocclusions affected 61% of the children examined. There was a positive correlation between total CPQ8-10 and DAI scores (P = 0.034). The following types of malocclusion had a significant effect on the quality of life of the children: upper anterior irregularity ≥ 2 mm, anterior open bite ≥ 2mm and diastema ≥ 2mm. Children with malocclusion experienced a greater negative impact on quality of life in comparison to those without malocclusion. Conclusions: Malocclusions had a negative influence over the quality of life of children between 8-10 years of age. More severe malocclusions had a greater impact with regard to social, emotional and functional aspects.

The Impact

<p>The aim of the study was to assess the impact of cut vegetative shoots of chosen lawn grass cultivars of <em>Festuca</em> being left on the lawn sward surface on the species composition, sodding and appearance, and over-wintering of the lawn. The influence of decomposing biomass was studied in a field experiment between 2008 and 2014. Each cultivar was sown as a monoculture on microplots with an area of 1 m<sup>2</sup>. The control consisted of sites from which the cut sward had been removed immediately after cutting.</p><p>The results obtained may indicate an allelopathic effect of the cut sward of the cultivars left on the lawn surfaces. The following had the most negative effects on the species composition of the lawn sward (from greater to lesser negative impact): <em>F. ovina</em> ‘Espro’, <em>F. rubra</em> ‘Areta’, <em>F. arundinacea</em> ‘Asterix’, and <em>F. ovina</em> ‘Pintor’. With the exception of ‘Espro’, these cultivars also limited the presence of dicotyledonous plants in the lawn sward. The cover of dicotyledonous plants and other unsown grasses was also recorded on the sites with <em>F. rubra</em> ‘Olivia’ and ‘Nimba’. The greatest negative influence on the sodding of the lawn swards was demonstrated by the latter <em>F. rubra</em> cultivar, whereas <em>F. ovina</em> ‘Espro’ had the greatest negative influence on the appearance. However, no differences were found in assessments of over-wintering of the cultivars at the study sites. However, taking into account the scale of these impacts on the characteristics evaluated, the cultivars of <em>Festuca</em> species tested can be recommended for extensive use, where a cut sward can be left on the surface of the lawn. Some caution in this respect is recommended when it comes to <em>F. ovina</em> ‘Espro’ and <em>F. rubra</em> ‘Areta’ and ‘Nimba’.</p>

Background. Prison units are marked by structural deficiencies, especially in relation to the female gender. Objectives. To measure the self-perceived impact of oral health on the quality of life of Brazilian women in detention. Methodology. A survey was carried out conducted in the penitentiary at Juiz de Fora (Minas Gerais, Brazil) using an instrument with semistructured questions and validated scales, including the Oral Health Impact Profile-14. 99 women were interviewed. The analysis was based on a theoretical model of determination, with hierarchical blocks of variables. Bivariate analysis was done using the Mann–Whitney, test and multivariate analysis was used using linear regression. The significance level was set at 5%. Results. 33% experienced tooth loss after incarceration, (3.70 ± 3.26 lost teeth). 65.6% rated the dental service as fair/poor. The highest prevalence of oral health impact was for the domains of psychological discomfort (50.5%) and physical pain (40.4%). There is a negative impact on psychological discomfort: the number of dental consultations in the past year and self-perceived general health. There is an impact on physical pain: self-declared color and anxiety. Self-perceived general health had an impact on the domains of psychological disability and social disadvantage. Depression had an impact on the total score. Conclusion. This study revealed a self-perceived impact of oral health on the quality of life of women inmates. We need to ensure high-quality access to dental treatment in prisons.
