The Relationship Between Self-Compassion and Symptoms of Physical Deformities in Adolescents

Current-focused detection education Adolescent self-compassion and physical deformity symptoms, and demographic inequalities. The sample included N=293 teenagers. Study goals were met using the self-compassion measure. (Neff et al., 2021) The External Appearance Anxiety Scale (Park, 2007) and external rejection sensitivity meter (Roberts et al., 2018). The study demonstrated a positive link between self-compassion and sensitivity to appearance-based rejection (R=0.345) and anxiety about outward appearance (R=0.553). Teens with physical abnormalities had an average arithmetic mean of 3.26 self-compassion. Two sections rated very high, four scored about average, and outward appearance concern had an arithmetic mean of 2.63. It was also found that there was a statistically significant difference at the level of statistical significance (α = 0.05) according to the gender variable on the scale of rejection sensitivity due to appearance, and there were no differences on the rest of the scales, and there was no difference on anxiety about external appearance according to the school level variable, and there were no differences on the rest of the scales, and there were differences on self-compassion and anxiety about external appearance, and there were no differences on the rejection sensitivity scale due to appearance attributed to the weight variable, and there was a difference in empathy with Self and there are no differences on the rest of the scales according to the variable "Have you performed an operation," and it was found that the differences in the gender variable came in favor of males compared to females, while the differences in weight came between the category "my weight is commensurate with my height and I have excess weight by more than 20%" and the category "my weight is proportional to my height" and the differences were in favor of the first category, and with regard to the variable differences according to the order between my brothers and sisters, the dimensional comparisons show that there are differences between the first or second category and between The latter category and in favor of the first and second, and finally it was found that there is a statistically significant contribution at the level of significance (a = .05) for the variables of the study These characteristics account for 4% of self-compassion variance, but they predict plastic surgery exposure greatest, current weight second, and gender least.

Morphological characteristic analysis of dry fruits of annatto (Bixa orellana L.)

The present research work was performed to explore the engineering properties of annatto (Bixa orellana L.) fruits and seeds in dried large and small variety. The geometric properties (length, breadth, thickness, arithmetic mean diameter, geometric mean diameter, sphericity, aspect ratio and surface area), gravimetric properties (bulk density, true density and porosity) and frictional properties (angle of repose and static coefficient of friction) were determined for small pods, large pods, small seeds and large seeds of annatto fruit by following standard methods. The moisture content of dried annatto fruits were ranged from 11.27 to 9.36% (w.b.) and for the seeds 6.67±1.5% (w.b.). The average arithmetic mean diameter of large pods was 30.33±3.19 mm and for small fruits was 23.49±2.29 mm. The true density, bulk density and angle of repose were also determined for small and large pods and seeds. The coefficient of friction was maximum (0.53±0.05) for small annatto pods in cardboard surface and minimum (0.14±0.057) for large dried pod in rubber surface. These properties finds application in developing a power operated decorticator to ease the separation of seeds from annatto pods without losing its valuable pigment present in its seed coat.

Survey of indoor radon (Rn-222) entry and concentrations in different types of building in Kalisz, Poland

Indoor radon (222Rn) was surveyed in a total of 141 individual houses and apartments used precalibrated passive PicoRad Detectors. The radon activity in the soil gas around the dwellings was simultaneously measured. The arithmetic mean values of indoor radon concentrations for detached houses, old buildings (up to four-stories), prefabricated blocks of flats (mostly five stories) and high-rise residential buildings (10-stories) were:, 70.9; 46.5; 38.4, and 56.6 Bq m−3, respectively. The average arithmetic mean value for all measured rooms equals 51.8 Bq m−3. The calculated average effective dose from indoor radon for the local population was equal to 2.2 mSv.

Porous Silica Nanotube Thin Films as Thermally Insulating Barrier Coatings

The fabrication and examination of a porous silica thin film, potentially for use as an insulating thin film, were investigated. A vertically aligned carbon nanotube (CNT) forest, created by chemical vapor deposition (CVD), was used as scaffolding to construct the porous film. Silicon was deposited on the CNT forest using low-pressure CVD (LPCVD) and then oxidized to remove the CNTs and convert the silicon to silica for electrical or thermal passivation (e.g., thermal barrier). Thermal conductivity was determined using a 1D heat-transfer analysis that equated radiative heat loss in a vacuum with conduction through the substrate and thin film stack. A comparison of the surface temperature differences between a sample film and a reference of comparable thermal resistance enabled determination of the increase in the thermal resistance and of the thermal conductivity of the films. For film thicknesses of approximately 55 μm, the cross-plane thermal conductivity was found to be 0.054–0.071 W m–1 K–1 over 378–422 K. This thermal conductivity value is in the range of other silica aerogels and consistent with the low gravimetric density of 0.15 g cm–3 for the samples. The film is also relatively smooth and flat, with an average arithmetic mean roughness of 1.04 μm.

Geothermal application of spectral gamma ray logging in the South Kansas Subsurface, USA

Spectral gamma ray (SGR) is a logging tool that allows computation of the radioactive heat produced through radioactive decay of uranium, thorium and potassium within rocks. Radioactive heat-producing rocks are common targets for geothermal exploration. Gamma rays have longer half-length life in comparison to other radiations generated during radioactive decay. This characteristic allows the gamma rays to permeate far enough through the media to be measured by a logging tool. Radioactive heat production in this study was computed using spectral gamma ray and density logs. High-temperature geothermal reservoirs could provide heat that could be used to produce electricity from steam turbines. To provide domestic hot water, space heating, or process hot water, both low- and high-temperature geothermal systems could be used. This article is a case study illustrating subsurface radioactive heat production (A) calculated using well log data recorded in 48 wells located at 16 counties in the South Kansas State, USA. The results show that radioactive heat production (A) varies from approximately 0.1 to more than 10 μW/m3, whereas the average arithmetic mean is 1.15 μW/m3 and the average standard deviation is 0.57 μW/m3, which varies with lithology. The high measurements of radioactive heat production (A) in the studied rocks are predominantly related to the respective increase in uranium content in both shale and carbonate formations that could be future geothermal targets.

Functional state of the adrenal glands with combination of their morphological reorganization at different stages of a posthypothermic period

The problem of human adaptation to extreme environmental factors, in particular to the cold, which is one of the most common, is relevant from general biological and medical points of view. In this case, morphological reorganization takes place in various organs and tissues, and sometimes the changes become irreversible. That’s why from a scientific and practical point of view it is important to assess the role of the cold factor, the influence of which is experienced by most living beings, in particular on the adrenal glands, which are among the first to react to changes in the internal environment of the body. The purpose of the study is to follow the dependence and to study the morphological and functional state of the adrenal glands at various stages after the action of general deep hypothermia. The morphological and functional state of the adrenal glands of white outbred adult male rats was studied using histological, electromicroscopic, enzyme-linked immunosorbent assay, fluorometric, and statistical methods of research in various periods after exposure to general deep hypothermia. The morphometric analysis of the thickness of the adrenal cortex zones, the diameter of the microvessels, the area of cells and their cores, both cortical and brain, was performed using the software VIAVISION Version 2. The average arithmetic mean (M) and the mean arithmetic mean (m) error using the software were determined. “Statistica-5,0”. The probability of the difference between the mean values and their errors was determined by the criterion of the Student. It has been established that at the height of the cold action, the levels of cortisol and adrenaline increase, along with hypertrophy of the cells of the fasciculate zone and the adrenal medulla. At the stages of the posthypothermic period, one more rise of corticosteroids is observed on the 7th day, while the concentration of catecholamines decreases. The hypertrophy of the adrenocorticocyte of the fasciculate zone persists until the 30th day, and the adrenocyte of the medulla lasts up to 7 days after the action of general deep hypothermia. On the 14th day, in the structural components of the hemomicrocirculatory bed, next to intracellular compensatory-adaptive phenomena, single microvessels with destructive signs of endothelial cells are noted. Until the 30th day, the vast majority of microvessels acquire the characteristic structure of the norm. These changes indicate a close relationship of the sympathoadrenal and hypothalamic-pituitary-adrenocortical systems. The results of the conducted research expand modern ideas about the features of angioarchitecture and the submicroscopic structure of the adrenal parenchyma, reveal the structural and functional bases of their restructuring after exposure to general deep hypothermia.

METHODS OF DIAGNOSING THE LEVEL OF CHOREOGRAPHY STUDENTS’ PROJECT SKILLS DEVELOPMENT

The article reveals the specifics of the projects method use in the practice of teaching choreographic art. The authors carried out the analysis of the studies devoted to the problem of using the project method in training future arts, in particular, choreography teachers. The emphasis is placed on the pedagogical orientation of the project activity of choreography students in higher educational institutions. The paper presents the description of the concept “project skills of choreography students”, which is considered in the plane of two interrelated directions. The first one is the ability to independently carry out choreographic projects, and the second one is the ability to apply project skills in pedagogical activity. Taking into consideration the peculiarities of the pedagogical and choreographic activity of the future head of the dance group, appropriate project skills were distinguished, namely: the ability to clearly formulate pedagogical goal, to choose relevant methods and to know diagnostic procedures; to create an integral composition of the project event according to the logic of the choreographic composition, to distribute roles and tasks according to the figurative and drama idea; to select high-quality choreographic material, to be able to evaluate its artistic and aesthetic values and pedagogical potential; to focus on implementing the idea of the project, conducting all organizational procedures for achieving the goal; to select relevant artistic and informational support for the planned project, to understand the essence of key concepts, thesaurus, to use them in accordance with the genre and content of the project event or local mini-project; to work in a team, to carry out communicative actions, to involve others in activity and communication; to independently find original solutions to organizational, creative, compositional tasks; to combine the possibility of creative self-expression with the tasks of creative development of others; to present the project and conduct a critical analysis of the implementation of projective actions and results obtained, the implementation of an adequate self-esteem.The methods of diagnosing choreography students’ project skills are substantiated as an important component of future teacher’s – the head of the choreographic team’s – professional competency. The article describes the elaborated criterial apparatus of research, consisting of such criteria as: cognitive, motivational and communicative, creative and activity-based, results and presentation-based. Each criterion is supplemented by an optimal number of indicators, the degree of their manifestation determines the level of students’ project skills. The empirical research methods were substantiated in regard to each criterion and its indicators. According to the cognitive criterion, the level of projection skills was revealed by the methods of questioning, interrogating, testing, conversation, interviewing; according to the motivational and communicative criterion – by the methods of observation, diagnostics, projects modification, dialogue; according to the creative and activity-based criterion – these were creative tasks, independent development of projects; according to the results and presentation-based criterion, these were methods of presentation, assessment of independent judges, interviews, tasks for reflection. The average arithmetic mean of the points received by each choreography student was determined over all stages of the summative experiment. The authors conducted analysis of the obtained data and described the results of the existing level of developed project skills of choreography students in the experimental group.

Antidepressant activity of 4-amino-5-(alkyl-, aryl-, heteryl)-1,2,4-triazole-3-thione benzylidene derivatives

The current market for antidepressants has a number of limitations, they have a high probability of development of adverse reactions, have low latitude and stability of the therapeutic effect, and also have a long latent period of action. Therefore, it seems obvious that there is a need to create new drugs that improve the quality of life, affect the mood and are safe. An analysis of literary sources has shown that derivatives of 1,2,4-triazole have a pronounced antidepressant effect and drugs such as Trazodone and Alprozalam are widely used in medical practice. The purpose of this work was to study antidepressant effects of 1,2,4-triazole derivatives and to make analysis of the dependence between chemical structure and pharmacological activity. Materials and methods. The search of antidepressants in the series of 1,2,4-triazole derivatives was performed on the basis of the classical model of R.D. Porsolt in the modification of E.V. Schetynin. Each animal was immersed for 6 minutes in a vessel filled with water at a temperature of 27 °C. The duration of active swimming was fixed (vigorous movements of all paws with active movement), passive swimming (weak bends of the paws necessary to support the body to swim) and immobilization (no swimming motions). In addition, the number of active swimming periods of different lengths and the number of very short immobilization periods of up to 6 seconds were counted. The index of depression (ID) was calculated due to the ratio of the very short periods number of immobilization to the total number of active swimming periods. The research results are processed by modern statistical methods of analysis using personal computer, including the standard program package Microsoft Office 2013 (Microsoft Excel) and Statistica ® for Windows 6.0. The average arithmetic mean (M) and standard mean errors (±m) were calculated. The statistical significance of intergroup differences according to the experimental data was established using Student's t-criterion. To study the dependence of the influence of benzylidene derivatives of 4-amino-5-(alkyl-, aryl-, heteryl)-2,4-dihydro-3H-1,2,4-triazole-3-thione on the duration of passive swimming and the duration of immobilization was carried out by correlation analysis. Results. Benzylidene derivatives of 4-amino-5-(alkyl-, aryl-, heteryl)-1,2,4-triazole-3-thione were used as test substances. The index of depression in the use of fluoxetine decreased to 70.92 % (P < 0.05), and with the use of trazodone to 76.95 % (P < 0.05). Compounds 26 and 32 statistically significantly lowered the index of depression to 86.66 and 81.24 %, respectively, which was higher than the activity of the used comparison drugs. The main indicator of rats despair was the duration of immobilization, decreased to 73.53 % (P < 0.05) and trazodone to 79.55 (P < 0.05) when administered with fluoxetine. When applying 1,2,4-triazole derivatives, the duration of immobilization of compound 32 was reduced to 89.53 % (P < 0.05), and compounds 23 to 87.05 % (P < 0.05). Conclusions. The most active compound according to the results of the study was compound 32, which reduced the average duration of immobilization in the experimental group to 89.53 % and had a rather low index of depression (0.34 ± 0.08, P < 0.05).

Occupational 50 Hz magnetic field exposure measurements among female sewing machine operators in Hungary

Occupational magnetic field (MF) exposure is less thoroughly characterized in occupations typically held by women. Our objective was to characterize occupational 50 Hz MF personal exposure (PE) among female sewing machine operators. We measured the full shift PE of 51 seamstresses, who worked in two shifts (6-14 and 14-22 h) according to their normal work routine. Measurements were conducted using EMDEX PAL meters at chest level. The average duration of the measurement periods was 449 min (range 420-470). The average arithmetic mean exposure for all women was 0.76 microT (range 0.06-4.27). The average of maximum values was 4.30 microT (range 0.55-14.80). Women working with older sewing machines experienced higher exposure than women working on newer sewing machines. For women (n = 10) who operated sewing machines produced in 1990 or earlier, the average arithmetic mean exposure was 2.09 microT, and for women (n = 41) who operated sewing machines produced after 1990, the average arithmetic mean was 0.43 microT. We conclude that women working as sewing machine operators experience higher than average occupational MF exposure compared to other working women. Most important determinant of the women's personal MF exposure was the age of the sewing machine the women operated.

No evidence for mesothelial cell contact across the costal pleural space of sheep

Pleural space width was measured by four morphological approaches using either frozen hydrated or freeze-substituted blocks of chest wall and lung. Anesthetized sheep were held in the lateral (n = 2), sternal recumbent (n = 2), or vertical (head-up; n = 2) position for 30 min. The ribs and intercostal muscles were excised along a 20-cm vertical distance of the chest wall region, which was sprayed with liquid Freon 22, cooled with liquid nitrogen, to facilitate the fastest possible freezing of the visceral and parietal pleura. We measured pleural space width in frozen hydrated blocks by reflected-light and low-temperature scanning electron microscopy and in freeze-substituted, fixed, and embedded tissue blocks by light and transmission electron microscopy. We combined the data from the two groups of sheep held sternally recumbent and vertical because the results were comparable. The average arithmetic mean data for pleural space width determined by reflected-light analysis for samples near the top (18.5 microns) and bottom (20.3 microns) of the chest, separated by 15 cm of lung height, varied inversely with lung height (n = 4; P less than 0.009). The average harmonic mean data demonstrated a similar gravity-dependent gradient (17.3 and 18.8 microns, respectively; P less than 0.02). Therefore a slight vertical gradient of approximately -0.10 micron/cm of lung height was found for costal pleural space width. Pleural space width in the most dependent recesses, such as the costodiaphragmatic recess, reached 1-2 mm. We never found any contacts between the visceral and parietal pleura with either of the frozen hydrated preparations. No points of mesothelial cell contact were revealed in the light- and transmission electron microscopic views of the freeze-substituted tissue, despite an apparent narrower pleural space associated with the tissue-processing steps. We conclude that the pleural space has a slightly nonuniform width, contacts if they occur must be very infrequent, and pleural liquid clearance is probably facilitated by liquid accumulation in dependent regions where lymphatic pathways exist.

Analysis and synthesis of seasonality and variability of daily potential evapotranspiration

Daily meteorological data over a period of nine years from Helliniko Station (Athens, Greece) are used to produce daily potential evapotranspiration (PET) series. A multipliative model describes the periodic and stochastic components of the series where Fourier aproximations of two- or three-harmonic periodic components and a first-order autoregressive one are employed, respectively. The assessment of adequacy of the model is based on the properties of (a) the correlogram and (b) the spectrum of a white noise process. The model is further used to generate daily PET values. Generated and historical data show remarkable affinity in average arithmetic mean, coefficient of variation, skewness coefficient and their standard deviations.
