This publication presents the results of the analysis of the dynamics of changes in the largefruited indicators of the breeding group of minipigs of the ICG SB RAS. The analysis showed that the four large-copious indicators are divided into two pairs. The first pair is made up of sample values of the characteristic: average and maximum. These indicators are characterized by stability throughout the studied period. The second pair includes the sample minimum values and standard deviations of the trait. These two indicators are dynamic: the sample minimum values are characterized by a decrease, and the sample standard deviations are characterized by a uniform increase, described by linear regression equations. It is shown that the dynamic characteristics are related to each other. It is determined that in this complex, the leader is the minimum value, and the follower is the standard deviation. This is explained by the fact that an increase in the standard deviation is associated with a decrease in the minimum value and the stability of the maximum in the studied period of time. The result of this process is the growth of the genetic potential in the breeding group, which is responsible for the high weight of the newborn individual. However, due to the small size of sows in comparison with commercial breeds (60-70 kg), this potential cannot be realized. Nevertheless, its redundancy ensures the stabilization of the maximum and average values of the trait - the mass of a newborn individual in minipigs of the ICG SB RAS. A possible way to increase the realization of the potential of large-copious breeding group is to reduce the multiple fertility of sows, which is quite solvable, but hardly advisable. Thus there is natural selection directed against individuals with a low birth weight in the herd. Natural and artificial selection for live weight of piglets at birth of 700 g or more, both help to stabilize the average value of the trait at the level optimal for the broodstock.

Teacher's Perspective

The study aimed at revealing the extent of achieving the goals of civic education in the light of the concept of globalizationin the curriculum of the civic and national education of high elementary schools from Aqaba teacher’s perspective.  The study population consists of all the teachers of the social studies in elementary schools at Aqaba Governorate for the year (2019-2020). It consists of 49 teachers distributed in 17 schools. The study tried to answer the following questions: To what degree the goals of civic education in the light of the concept of globalization in the curriculum of the civic and national education from Aqaba teacher’s perspective can be achieved? Are there any statistical difference in the teacher’s evaluations to achieve thecurriculum of the civic and national education based on gender and level of education? The study tools were a test and a questioner that measures the teachers’ view of the extent of achieving the goals of civic education in the light of the concept of globalization. Therefore it was divided into two parts one pertaining the citizenship values and the other one pertaining the goals of globalization. The researcher got the arithmetic averages and the standard deviations for each paragraph and for each field of the study. The stability coefficients of the study were measured individually in addition to the questioner coefficient of stability as a whole which was (0.78). The globalization stability coefficient was (0.78) and the civic education was (0.896) all of which are high and accepted stability coefficients. The arithmetic averages and the standard deviations were measured for the two parts of the study. It was noticed that the civic education got the lowest arithmetic average (3.01) and a standard deviation (0.91). As for the second part namely the globalization that got the highest arithmetic average (3.29) and a standard deviation (1.16). The researcher believes that the awareness of civic education and the goals of globalization are very important and should be included in the curriculum. Both come in accordance with the study conclusion.

Abstract The purpose of the research was to identify samples of the collection of peas with a high and stable protein content in the grain, as a starting material in breeding for grain quality. Of the 130 studied samples of the collection of peas, which had at least 25.0% of the protein content in the grain, on average over the years of research, only 13 samples had a protein content of at least 25.0%. The highest minimum protein content was observed in the Russian-bred OMK-3 sample, which had an indicator of 26.1%. For the rest, the minimum value was from 25.0 to 25.3%. The maximum protein content over the years of research in pea samples was from 25.8 to 29.7%, of which samples 193/73 (Ukraine) (29.7%), OMK-3 (Russia) (29.5%), NS-01-68 (Bulgaria) (29.1%), B-887 (Russia) (28.7%) and Orel-330 (Russia) (28.7%). The average value of the coefficient of variation for varieties, characterizing intravarietal variability, was 6.8% on average for the collection, with the lowest value being 1.2% and the highest value being 15.9%. In the 13 isolated samples, the intravarietal variability was lower than the average for the collection as a whole (1.2-6.6%), except for sample 193/73 (Russia), for which it was 7.3%. This sample has the highest average and maximum protein content in the years of research. The selected 13 samples from the pea collection are of breeding value as initial parental forms in the direction of increasing the protein content in the pea grain and enhancing the stability of this indicator.

The Stability

To ensure a smooth production, some stability indicators, including mean (μ), standard deviation (σ), standard deviation coefficient (V), as well as the probability (P) of variable values that fall within the scope of the standard were introduced to evaluate and to control the chemical composition and mechanical properties of seamless gas cylinder 30CrMo-M. Stability levels were defined according to the enterprise performance appraisal system. By using SPSS and MATLAB software, a regression equation was established that evolved chemical composition, tensile strength, yield strength and elongation. Tensile strength and yield strength are positive correlated with C, Si, Mn, and elongation is just the opposite. According to the stability indicators and regression equations, the entire mechanical properties meet the standard requirements by reducing Mn, Si content by 0.02%, while maintaining C content constant. According to the stability indicators, the best heat treatment system, quenching at 930 ~ 935°C for 40 minutes and tempering at 580 ~ 595 °C for 90 minutes, was established.

ABSTRACTMeasurements of the m. longissimus and overlying fat at the last rib were taken on the live pig using ultrasonic machines of differing complexity: Sonatest (simple A-mode machine), Scanogram and His Observer (modified linear scanners), and Danscanner (‘real time’ scanner). These measurements were examined as predictors of the corresponding carcass measurements and percentage lean in the carcass.Sonatest and Scanogram were compared using 143 purebred and crossbred pigs of different types. The analysis was pooled within breed-type and sex. The standard deviation for percentage lean was 3·94. Residual standard deviations for predicting percentage lean from live weight and best fat thickness were 2·72 (Sonatest) and 2·56 (Scanogram). Addition of m. longissimus depth (Sonatest) and m. longissimus area (Scanogram) reduced these to 2·69 and 2·29 respectively. The use of two or more fat measurements provided no extra precision over a single fat measurement.Scanogram and His Observer were compared using a subset of 38 pigs. Scanogram was a better predictor of percentage lean using a single fat measurement but when a combination of measurements was used, there was little difference between the machines.Scanogram and Danscanner were compared using a subset of 27 pigs. The standard deviation of percentage lean was 3·57. Residual standard deviations for predicting percentage lean from live weight, best fat depth and m. longissimus area were 2·18 (Scanogram), and 2·03 (Danscanner). Fat areas had similar predictive precision to fat thickness measurements.
