The research had the objective of determining the chemical composition of the wood o f Cedrela odorataL. and its relationship with the chemical properties of the soil in a forest ecosystem; for this purpose, five trees were taken as samples, from which a branch of one meter long of 10 to 20 centimeters in diameter was obtained and the analyses of ash, extracts, lignin and holocellulose of each sample were carrie d o ut; th e analysis of the level of pH, phosphorus and nitrogen of the soil was made. For statistical analysis, the non-parametric Kruskal-Wallis test was used with the Dunn test, and a bivariate correlation of Spearman was applied. In general, it was obtained that the holocellulose (62,97 %), is the most abundant component, followed by lignin (30,15 %) and with a lower percentage the content of extractable (5,64) and Ashes (1,24 % ). Th e soil where the individuals grew is very acidic (pH of4,70) with a medium p h os p ho rus level (33,74 ppm), and a high level of nitrogen (165,24 ppm). The relationship betw ee n the chemical properties of the wood and each of the chemical properties of the soil resulted in four relationships, two positive (phosphorus -lignin with a s ign if ic a n c e o f 0.1 and nitrogen -holocellulose with a significance = 0,01) and two negative (p H -a s h with a significance of 0,01 and nitrogen -lignin with a significance value of 0,04).

Además, se muestra un comportamiento con alto nivel de similaridad (84,4%) entre el uso del videojuego y responder satisfactoriamente los ítems. Esto nos sugiere que este medio educativo puede provocar mejoras en los aprendizajes del alumnado, quien parece ser proclive a su uso. The technological applications offered for education are varied, providing new learning possibilities. Gamification proposals for the classroom must be constantly monitored, since their development and use does not ensure success in teaching. We study the impact of gamification in the teaching of mathematics, analyzing its role in the treatment of geometric cone and cylinder figures with 13 and 14 years old students. From a descriptive quantitative approach of quasi-experimental type, with a control and pilot group and test application, a classical and implicative statistical analysis is carried out, showing a higher percentage of correct answers from the pilot group, in the item on the relationship between the volume of the cone and the cylinder, with 96.3%, in contrast to 73.08% obtained by the control group. In addition, a behavior with a high level of similarity (84.4%) is shown between the use of virtual games and satisfactorily answering the items. This suggests that this educational medium can cause improvements in the learning of students who seem to be prone to its use.

In early 2020, WHO stated that Coronavirus Disease 2019 (Covid-19) is a new type of coronavirus with high transmission and fatality. Indonesia is one of the countries exposed to Covid-19, where there has been a fluctuation in the number of victims exposed to Covid-19 since March 2020. Sragen Regency is one of the areas affected by Covid-19. This study aims to determine the level of vulnerability of the Sragen Regency to the Covid-19 pandemic and analyze the relationship between regional vulnerability and the number of Covid-19 cases (suspect, probable, confirmed, and discarded cases) in Sragen Regency. This research was conducted quantitatively by descriptive and inferential statistical analysis using the Spearman Rho test, preceded by tests of normality and homogeneity as a prerequisite test. The results indicated that the vulnerability of the Sragen Regency to Covid-19 was classified into high, medium, and low classes. High class dominated in 11 districts, medium class in 8 districts, and low class in 1 sub-district. Furthermore, the Spearman's rho test results were 0.084>0.05, which means that there was a relationship between the regional vulnerability variable and the number of Covid-19 cases, but it was not significant. That is because of the effective handling of the Covid-19 pandemic and the high level of community awareness in the Sragen Regency.Keywords: Covid-19, Disaster, Pandemic, Regional Vulnerability, Sragen

AbstractKidney stones are mainly composed of inorganic crystals such as calcium oxalate (CaOxa). At present, kidney stones can be detected only after their formation, which causes great suffering for patients. If kidney stones can be detected prior to their formation, they can be effectively prevented, which presents great commercial value. In this paper, we review the differences in urine nanocrystallites between stone-forming patients and healthy controls, as well as the relationship between nanocrystallites in urine and the formation of kidney stones. These differences are microcrystalline morphology, aggregation, size and distribution, chemical composition, Zeta potential and stability. The results showed that the formation of kidney stones is closely related to the nature of nanocrystallites. Through the regulation of the physical and chemical properties of nanocrystallites, the formation and recurrence of kidney stones are possibly inhibited.

The work performed allowed us to determine the correlation of giftedness, level of intelligence, academic success and conscious self-regulation in children of young adolescents. Diagnostics was carried out using the “Creative Field” method (D. B. Bogoyavlenskaya), the “Progressive Matrices” test (J. Raven) and the rapid method «Style of Self-regulation of Children Behavior» SSCB-M1 (V. I. Morosanova). The results were obtained as part of a longitudinal study from primary school to adolescence. Statistical analysis is represented by correlation analysis and the method of constructing regularized networks of patial correlations glasso using the language R. Giftedness is understood by us as the ability to develop activities on our own initiative. Mathematical analysis reveals an indirect connection between giftedness and a cluster of conscious self-regulation through an intelligence index. The negative sign of the connection between intelligence and the “planning” scale is explained by the characteristics of the age under study: the breadth of interests, the situation of choice and the criticality of children with a high level of intelligence, which leads to lower grades.

Ductile Shear Deformation

Under influence of ductile shear deformation, granulite facies mineral paragenesis underwent metamorphism and changes in chemical composition. The present paper discusses some changes in chemical composition of garnet in hypers thene_absent felsic gnesiss and of hypersthene in rock in early and late granulite facies undergone increasing ductile shear deformation .In garnet fetsic geniss, band structures were formed because of partial melting and resulted in zoning from massive⟶transitional⟶melanocrate zones in increasing deformed sequence. The electron-probe analyses for garnet in these zones are listed in table 1 . The Table shows that Mno, Cao contents in garnet decrease swiftly from slightly to intensely deformed zones.In slightly and moderately deformed zones, Mgo contents keep unchanged and Feo is slightly lower. In intensely deformed zone, Mgo contents increase, indicating a higher temperature. This is in accord with the general rule that Mgo contents in garnet increase with rising temperature.

AbstractBackground: Comprehensive cardiac rehabilitation (CR) is a process designed to restore full physical, psychological and social activity and to reduce cardiovascular risk factors. Fear of movement may contribute to the occurrence and intensification of hypokinesia, and consequently affect the effectiveness of therapy. The aim of the study was to determine the level of barriers of physical activity in patients undergoing cardiac rehabilitation. The relationship between selected determinants (age and health selfassessment) and the kinesiophobia level were also examined.Material/Methods: 115 people aged 40-84 years were examined: 50 females (x = 63.46; SD = 11.19) and 65 males (x = 64.65; SD = 10.59) - patients undergoing cardiac rehabilitation at the Upper-Silesian Medical Centre in Katowice. In the present study, the Polish version of questionnaires: Kinesiophobia Causes Scale (KCS) and Short Form Health Survey (SF-36) were used. Questionnaires were supplemented by authors’ short survey.Results: The patients presented an elevated level of kinesiophobia, both in general as well as in individual components. In women, the kinesiophobia level was higher than in men. The psychological domain was a greater barrier of physical activity than the biological one. Strong, negative correlations of psychological and biological domains of kinesiophobia to physical functioning (SF-36) were noted in women. In the case of men, correlations were weaker, but also statistically significant.Conclusions: 1. Sex differentiates patients in their kinesiophobia level 2. Poor self-assessment of health is associated with a greater intensification of kinesiophobia 3. A high level of kinesiophobia may negatively affect cardiac rehabilitation process
