This study was conducted to compare three different methods for calculating scrotal circumference (ASC1, ASC2, ASC3) adjusted to 365 days of age in Charolais, Limousin and Hungarian Fleckvieh young bulls at the end of the self-performance test. Young breeding bulls from three Charolais, Limousin and Hungarian Fleckvieh breeding farms (farm A: n = 40; farm B: n = 9; farm C: n = 11) were used. The young bulls were kept in loose housing system, in small groups, and fed a diet based on maize silage and concentrate. The scrotal circumference of young bulls was measured at the widest part of the scrotum at the beginning and at the end of the test. Significant growth was observed (+13.6 cm; +8.9 cm; +10.5 cm, P < 0.001) in scrotal circumference (SC) for all breeds except the Hungarian Fleckvieh (ASC2-ASC3: 37.5 vs. 37.6 cm). All differences among the means of the measured and adjusted SCs were statistically confirmed at the P < 0.05 level of significance. A moderate to close positive correlation (r = 0.49-0.99) was calculated among the measured SC and the three types of ASC. The results suggest that method I (ASC1) and method II (ASC2) should be used by the breeders for adjusting scrotal circumferences in the practice.

Objective: This cross-sectional observational study was accomplished at Isra University to evaluate the self-apprehension of dental students related to their own smile. Material and Methods: This study was comprised of 166 dental students belonging to both genders. A structured selfadministered questionnaire was used to conduct a survey among undergraduate dental students at all study levels in Isra University. Questionnaire was designed to observe the self-apprehension and satisfaction of students with reference to their dental appearance. Data analysis was done using descriptive statistics via 21st version of SPSS. 0.05% was established as the level of significance. Results: 166 students (32 males and 134 females) participated in this survey. 32.5% students were shy as against 91.6% students who were bold at smiling in public. 55.4% students preferred to be photographed from side pose while 69.9% were inspired by other’s smile. In terms of teeth dimensions, 60.2%, 54.8% and 46.4% students were gratified with the length, breadth and form of their teeth respectively. Conclusion: This study concludes that greater number of dental student were self-assured regarding their apprehension on their own dental appearance. Majority of the females though contented with the dimensions and contour of their teeth, urged to have lighter teeth.

Relationships of scrotal circumference (SC) with body weight (BW) and backfat thickness (FT) as measured from scanograms were studied. A total of 935 observations on growing multibreed synthetic beef bulls on a postweaning performance test were available from a commercial herd for this study. Significant breed group, period and group × period interaction effects were noted on SC, BW and FT. BW and SC increased significantly during the test in all breed groups, while FT showed no change in three breed groups. Repeatability pooled across groups for SC was estimated as 0.72; 0.66 after adjusting for BW. Significant correlations were noticed between SC and BW within each breed group. Partial correlations between SC and BW at constant FT were not different from gross correlations. Linear regression coefficients of SC on BW were significant in all groups and showed heterogeneity among groups but not between periods within groups. Adjustments of SC for BW should, therefore, be breed group specific. BW alone accounted for considerable variation in SC, from 38 to 76%. Simple correlation coefficients between SC and FT were low and significant in only two groups. A significant but low positive relationship was noted between SC and FT at constant BW in a group fed a high-concentrate diet during the postweaning gain period, but there was no relationship in four other groups. Results indicated that the method of adjusting SC for FT as an indirect way of adjusting for scrotal fat was not satisfactory. Key words: Bulls, scrotal circumference, growth

Benefiting from self-healing features, metallized film capacitors (MFCs) are widely employed to compensate reactive power (VAR) and thus improve the performance of AC systems. To ensure the aforementioned functions, self-healing testing is a compulsory quality inspection for every type of MFC. In 2014, the International Electrotechnical Commission (IEC) issued a standard that recommended a general and instructive test procedure based on audible noise or ultrasound signals. However, more details relevant to this high voltage (HV) test were not provided. In this paper, we focused on the ultrasonic detection technique to reveal the self-healing characteristics of two typical MFCs. By launching a series of HV tests with star and delta MFCs, the waveform features, discharge energy, and spectrum distributions were analyzed. It was observed that the partial discharge always occurs before self-healing discharge with the same spectrum features ranging above 40 kHz. To solve the entanglement of these two discharge processes, a relative amplitude difference method is proposed. Based on the experimental observations, a detection algorithm incorporated with the ultrasonic emission sensors, preamplifier, and high-speed A/D converter was developed to assist the self-healing performance test.

The fertility of beef bulls which completed performance test in the Ontario Bull Test Program was measured by classification of success as breeders according to surveys of consignors to test, by classification of satisfaction in surveys of users of tested bulls and by measurement of calf crop percentages and birth dates of progeny relative to herdmates in the Ontario Beef Herd Improvement Program. Consignors classified 3.0% of the 2556 bulls with completed information as unsuccessful breeders. Users rated 61.5% of the 411 bulls with information from the participant survey as very satisfactory and 4.5% as very unsatisfactory. The effects of end of test weight, gain index, backfat and scrotal circumference on calf crop percentage (cows calving relative to cows exposed), percent of calves born in the first 3 wk of the calving season, percent of calves born in the first 12 wk and satisfaction score were generally small and nonsignificant as tested within breed for 122 Angus, 451 Charolais, 632 Hereford, 575 Limousin and 501 Simmental bulls. In general, gain on test and end-of-test measurements were not found to have any association with subsequent fertility of bulls tested. There was no evidence that increased scrotal circumferences were associated with increased measures of productive performance nor that increased fatness, within the range included in the Ontario Bull Test Program, decreased reproductive performance.

Decision refers to the act of choosing the most appropriate type of action possible according to present possibilities and conditions in order to achieve an aim. Decision making covers all cognitive and behavioral effort for choosing and preferring in the face of various situations and events. Starting from this point of view, in our study, it was aimed to investigate prospective kickboxing students’ self-esteem in decision making and decision making styles.The study included 62 voluntary prospective coaches, who participated in a kickboxing coaching in the city center of Elazığ in 2017. In order to obtain personal information from the participant prospective coaches in the study, a personal information form (age, gender, years of doing sports) was formed. In order to investigate the self-esteem in decision making and decision making styles of prospective kickboxing coaches, the Melbourne Decision Making Questionnaire, which was originally developed by Mann et al., (1998) and adapted into Turkish by Deniz (2004), was utilized. The obtained data were evaluated by using SPSS statistics package software and the level of significance was regarded as p<0.05.As a result of the study, according to participants’ variables of age, gender and years of doing sports, the comparison of prospective teachers’ decision making and decision making style mean scores did not constitute a statistically significant difference. The self-esteem levels of coaches in decision making were observed to be significantly high.

Observations were made on 13 pre-adolescent diabetic boys at a summer camp. Glucosuria, hypoglycemia, dietary intake with self-regulated and prescribed diets, emotional adjustment and measures of group structure were recorded and correlated to determine the relationship between psychologic-sociologic factors and metabolic changes in the diabetic state. Average values for glucosuria for the entire group indicated that during the period of a prescribed diet, the per cent glucose in the urine was not statistically different during any of the three periods of the 24 hours. With the self-regulated diet there was a significantly greater per cent glucose in the urine during the day and evening periods than during the night period. The type of diet the boys had received at home did not affect their performance during the two dietary programs. There was less hypoglycemia and a higher per cent glucose in the urine during the day with the self-regulated diet than with the prescribed diet. These differences were significant, with a P value of less than .025. There was no difference in glucosuria during the night collection with the two dietary programs. Well adjusted boys had less of an increase in glucosuria when they went from a prescribed diet to a self-regulated one than did the poorly adjusted boys. The differences in glucosuria were partially correlated with the differences in caloric consumption, the poor adjustors having a greater increase in calories consumed than the good adjustors. These changes did not reach the .05 level of significance. Eating as a preferred activity increased in prominence during the course of the study. Group structure did not become well defined with these boys because of the lack of a cabin-oriented program in the camp, so no correlation could be made between group position and change in glucosuria.

Transactional Costs

The authors examine the mathematical modeling of methods for the coordination of collective action in the self-organization and self-governance mode. It is assumed that members of the collective create aggregate income whose value grows, as each member invests more effort. The goal pursued by each member of the collective is to maximize personal gains. As we established in the first part of the study, the lack of universal interpersonal trust prevents members of a uniform (unstructured) collective from overcoming a non-effective, Nash equilibrium outcome. Alternative options for structuring the collective were considered, such as creating small groups (coalitions) of agents sharing mutual trust within each group. The strategy of such coalition, aimed at maximizing coalitional gains rather than personal, leads to greater investment of effort by each coalition member, which in turn produces greater aggregate gains for the entire collective. We have shown that in order to secure stability of a coalition structure, first, stimuli for each coalition member are needed such that imply redistribution of quasi-rent to their benefit, and second, control must be exercised on the efforts of the agents. As models demonstrate, members of the collective left outside coalitions or forming small coalitions with a low share taken together (in aggregate) gains, have weaker stimuli for investment. The potential of increasing such stimuli and thereby increasing aggregate gains may be furnished by another, stronger hierarchic-shaped structure – provided transactional costs are sufficiently low. In order to realize this potential, entitlements to residual income must be concentrated in the hands of a single largest coalition or a number of largest coalitions, while banning all other members of the collective from receiving such income. The income of each agent is defined by the terms of the stimulating contract. We have proposed a general design of such a stimulating contract, creating all prerequisites for achieving equilibrium outcome, with Pareto-dominates equilibrium outcomes for other collective structuring options.
