This paper analyses the progress and impacts achieved after their implementation both globally and in Georgia. The work mainly uses the qualitative method of research, which is divided into 2 stages: the analysis of secondary sources and in-depth interviews. In the case of Georgia, the main emphasis in the research was made around the renewable energy sector, because at this stage the country has one of the biggest prospects of getting closer to the sustainable development model through the development of a specific field. As a result of the research, it was confirmed that, as well as specifically in the context of Georgia, as well as on a global scale, the implementation of sustainable development goals in activities is hindered by low awareness in society. As for the impact on business, research has shown that specific concepts have a uniquely positive impact on both the private sector and the quality of life in general. Specifically, in the case of Georgia, the gaps in the involvement and readiness of the state institutions were highlighted. Achieving the goals set in a specific direction requires the involvement of each individual and the maximum understanding of the existing perspectives and needs in order to effectively and powerfully implement the goals in the activities, which will give you a relevant impact on the business and the quality of life in general.

Objectives: This study compared the efficacy of the XP-endo retreatment (XPER) system in removing TotalFill HiFlow BC (Bioceramic) and TotalFill BC sealers from dentinal walls to that of the ProTaper Universal retreatment (PTUR) system using micro-computed tomography (micro-CT) analysis. Materials and methods: Forty human-extracted single-rooted mandibular premolars were decoronated, and the roots were randomly divided into two main groups of 20 according to the retreatment system used (PTUR or XPER), and each group was divided again into two subgroups (n = 10) based on the sealer type used (TotalFill HiFlow BC or TotalFill BC). All root canals were instrumented and obturated. After two weeks, the retreatment procedure was performed using both systems. All specimens were scanned with a micro-CT device after obturation and again after retreatment, and the volume of root-filling material removed was measured. One-way analysis of variance and independent t-tests were used for statistical analysis. Results: XPER removed 88% � 14.57% of the root canal filling material in the apical third, which was significantly (p = 0.000) more than that removed by PTUR (62.7% � 24.95%). Overall, XPER removed significantly more HiFlow BC (94.66% � 10.75%) than conventional BC sealer (92.66% � 10.31%). Conclusions: XPER was more efficient than PTUR in the BC sealer retreatment at the apical root third. Moreover, the use of HiFlow BC sealer with continuous wave obturation made the retreatment easier as compared with conventional BC sealer with single cone obturation.

Growing concern of carbon dioxide emissions, greenhouse effects and rapid depletion of fossil fuels raise the necessity to produce and adopt new eco-friendly sustainable alternatives to the internal combustion engine driven vehicles. For this reason, in the last decade, electric vehicles have become in some way widespread, principally because of their negligible flue gas emissions and lesser reliance on oil. Although electric cars were introduced many years ago, agriculture electric vehicles have recently gained attention. The world of agriculture has changed, small specialized farm utility vehicles are now used for a specific purpose, and in several cases they have an electric engine. In our research, we focused on the design and preparation of a prototype the variable, multifunctional ecological electric loader, which would be dimensionally adapted to the needs of use in greenhouse, interior growing halls, as a result of research by students of innovative dual technical education with effective support of their teachers. The research deals with specifically the solution of aluminium welding by the TIG method, because the prototype frame is the welding of aluminium parts. The result of our research was the design and construction of a prototype of a smaller electric loader, which meets demanding quality parameters (performance) and environmental attributes (reduced noise and almost zero emissions) for work in greenhouses. The benefit of our research is the design and actual implementation of a prototype of a different ecological �green� electric loader, which is still missing on the market in the agricultural sector and is the output of creative innovative technical education in the environment of secondary vocational schools

Groundnut is an important cash crop and a diet component for rural households in sub-Saharan Africa. However, Aflatoxin contamination remains a barrier to promoting groundnut-based food products as food levels above maximum limit (ML) can adversely affect human health. Three objectives were set, namely, (i) to characterize the post-harvest operations and risk factors affecting aflatoxin contamination, (ii) to assess aflatoxin incidence in on-farm stores and, iii) to assess agronomic practices that can be integrated to improve yield and reduce aflatoxin contamination. The average aflatoxin levels in on-farm stores ranged from 11.3 to 16.4μg/kg, and the proportions of ML were 25.7% at 4μg/kg, 56.3% at 15μg/kg and 80% at 20μg/kg (~5 to 7 months after harvest). The application of Aflasafe® reduced aflatoxin contamination to safe level across the locations. Postharvest operations showing significant hazards include intermittent rain at harvest and drying (6.5), insect pests attacks after harvest (6), prolonged harvest to stripping interval (6.6), drying on bare ground (6.2), storing on bare floor (6.9), use of low efficient shelling machines (6.5) and re-use of rejected nuts (6.1). The potential increase of pod yield when best practices were adapted was in order of Triple Super Phosphate fertilizer (25.6-84.2%), YaraLegume fertilizer (18.4 to 52.7%), Rhizobium inoculant (14.6 to 45.8%) and Aflasafe® (5.5 to 43.1%). This study provides solutions to minimize aflatoxin risk if appropriate technologies (e.g. improved variety, fertilizer, Rhizobium inoculant, and Aflasafe®) and policies are deployed. In addendum, good drying and storage conditions are significant to optimizing benefits from good agronomic practices. Interventions to address cost limitations which hinder the adoption of these technologies require critical policy consideration.

This research aimed to assess the effectiveness of a plyometric training regimen in improving agility, speed, and social interaction among boys with mild intellectual disability (ID) aged 10-12, within the context of the Special Olympics. The study involved thirty-two boys (average age = 10.69 ± 0.8 years; average IQ = 61 ± 7) from three inclusive education centers. Over a period of 10 weeks, participants engaged in a plyometric training program twice a week. Evaluations were conducted before and after the intervention using the Reaction Time Test, 4-Corner Agility Test, 10-Meter Speed Run, 4x5 Meter Relay Test, and the Friendship Activity Scale (FAS). Significant improvements were observed across all measures. Reaction time decreased by 0.83 seconds (t = 7.44, p < 0.001), agility improved by 0.77 seconds (t = 11.93, p < 0.001), 4x5 meter speed increased by 0.61 m/s (t = 17.37, p < 0.001), and 10-meter run speed improved by 1.55 m/s (t = -12.76, p < 0.001). Furthermore, the FAS score rose by 0.81 points (t = 9.59, p < 0.001), indicating a boost in social interactions.The plyometric training program significantly enhanced agility, speed, and social interaction in children with mild intellectual disability, demonstrating its efficacy as an inclusive physical education strategy within the Special Olympics framework.

AIMS Copper nanoparticles (CuNPs) etch and rinse (ER) adhesive on the survival rate of Streptococcus mutans (S.mutans) micro tensile bond strength (μTBS) and Degree of conversion (DC) with carious dentin. METHOD Mandibular teeth with carious lesions were included. S.mutans were inoculated on CAD. Samples were allocated based on the application of Opti Bond FL primer modified with CuNPs in different concentrations. Group 1: Unmodified ER adhesive, Group 2: 0.1wt% CuNPs+ER adhesive, Group 3: 0.5wt% CuNPs+ER adhesive, and Group 4: 1wt% CuNPs+ER adhesive. Samples inoculated with S.mutans underwent evaluation of their survival rates. Samples were restored and underwent μTBS and failure mode assessment. DC was assessed using FTIR. Statistical analysis was conducted using ANOVA and Tukey test to evaluate significant differences across groups in terms of antibacterial potency, μTBS of ER adhesive, and DC RESULTS Group-4 (1wt%CuNPs+ER) treated teeth exhibited the minimum bacterial survival. Group-1 (Unmodified ER adhesive) showed maximum scores S.mutans survival. The highest bond of composite to the CAD was observed in Group-3 (0.5wt % CuNPs + ER adhesive) samples. μTBS was found to be lowest in Group-1 CONCLUSION CuNPs to an etch and rinse adhesive system at a concentration of 0.1wt% is a practicable way to provide adhesive interfaces with antimicrobial activity while also improving μTBS.

The contribution is focused on key competences and on the de-velopment of key competences of primary school pupils in the subject of Tech-nology (work-based teaching) in the Czech Republic and Slovakia. In the first part, the authors describe the concept of key competences, competences in the work of a teacher, and then the authors reflect on the key competences that pupils should achieve in the subject of technology after finishing primary school and show some possibilities for achieving these competences. In the second part of the article, the authors used the questionnaire method to investigate what competencies students acquire during lessons in the subject of Technology. The research sample consisted of 3516 pupils from the Czech Re-public and Slovakia. When comparing the results, it is shown that approximately the same results are achieved in the subject of Technology and they also show the students' preference for materials in their work. The aim of this contribution is to point out the importance of developing the key competences of pupils in the subject Technology, Work-based teaching and in the empirical part to try to show what competences pupils will acquire in pri-mary school.

In this paper, we propose a new approach for solving Volterra integral equations. The technique is based on the Chebyshev spectral collocation method. The application of the proposed method leads Volterra integral equation to a system of algebraic equations that are easy to solve. Some examples are presented and compared with some methods in the literature to illustrate the ability of this new method. The results demonstrate that the new method is more effcient, converges and accurate to the exact solution.

There are many evidences of which indicated that endocrine disruptors are responsible for different wildlife crisis. One of the methods for predict the effects of contaminants is the gene expression. In this study, we evaluated the expression of genes involved in the vitellogenin production by analysing of mRNA in Atlantic Angel Shark (Squatina dumeril) for applied these biomarkers on wild species.

This investigational study describes the fresh and hardened properties of self-compacting concrete (SCC) with accumulation of 0%, 10%, 20%, 30% and 40% coal bottom ash (CBA) as sand substitute ingredient. However, the fresh properties were explored by slump flow, T50 flow, V-funnel, L-box, J-Ring sieve segregation test. Moreover, the hardened properties of concrete were performed for compressive, splitting tensile, flexural strength and permeability of SCC mixtures. Fresh concrete test results show that even if no viscosity modifier is required, satisfactory fresh concrete properties of SCC can be obtained by sand substitute ingredient with coal bottom ash content. At 30% sand substitute ingredient with coal bottom ash (CBA) maximum compressive, tensile and flexural strength is observed which is 14.55%, 14.6% and 14.65% more than that of control mix respectively and maximum reduction in water penetration depth which is 40.04% less than that of control mix is observed at 28 days age. It can be concluded from this study that 30% sand substitute ingredient with coal bottom ash is optimum.

The reinforcement of concrete to enhance its strength specially the tensile and flexural strength has been widely adopted technique. In this investigational study, combination of different fractions of synthetic fiber nylon and nature fiber jute are used in concrete to assess the workability, density, water absorption, compressive, tensile, and flexural strength, and drying shrinkage of concrete. It was observed from results of research, that the maximum compressive strength, split tensile strength and flexural strength was observed to increase by 11.71%, 14.10% and 10.38% at 1% addition of nylon fiber and jute fiber together by the volume fraction after 90 days respectively. However, the water absorption of concrete was inclined with accumulation of nylon and jute fiber together after 28 days and drying shrinkage of concrete was reduced with addition of nylon and jute fiber together after 90 days. Moreover, the density and workability of concrete decreases with increasing content of nylon fiber and jute fiber together by the volume of fraction. The results of this study suggested that 1% combined addition of nylon and jute fiber is optimum for development of stiffer and durable concrete.

Taking into consideration the specifics of the Russian economy such as dependency on oil and gas drilling & production, and including the current context of the Western sanctions, COVID-19 pandemic, as well as somewhat idiosyncratic potential output development, the main aim of this paper is to quantify recent output gap for Russia. We use three mainstream methodologies: the Hodrick-Prescott filter as a benchmark, the Kalman filter to follow, and the Cobb-Douglas production function. The sample time span ranges from 1995Q1 until 2020Q3, while all calculations are performed on quarterly frequencies. The analysis suggests that given low fixed investment ratios, limited R&D spending in non-military sectors, and adverse demographic development, under a “no policy change” scenario there might soon be even more downward pressures on the country’s potential output growth, and the economy may continue increasing only at a snail’s pace even after a possible withdrawal of the Western sanctions and the end of the COVID-19 pandemic.
