The purposes of the present study are to compare the temperament of calves of different breed and sex at weaning, to analyse the effect of temperament on weaning performance, and todefine the correlations  between the previous traits. In the experiment carried out in Gelej in 2006 the behaviour of 61 Aubrac and 25 Charolais calves (39 heifer and 47 bull calves) wasassessed at weaning. The weight (WW) and the age of animals were detected, in addition temperament (TEMP) of them was scored. The weaning age (AU: 190±16.96 days, CH: 176±14.94days; P<0.001) and the weaning weight adjusted to 205 days of age (CWW) (AU: 192.39±31.32 kg, CH: 213.80±23.99 kg; P<0.01) of the two breeds significantly differed of each other. Thetemperament of calves was evaluated by scale test on a 5-point scale during weighing. The data were processed by SPSS 14.0 program package (Mann-Whitney U test, MANOVA, Tukey test,Spearman rank correlation test). Significant difference was revealed between the two breeds in TEMP (AU: 2 scores and CH: 3 scores; P<0.001), furthermore also difference was provenbetween the bull calves of Aubrac and Charolais in the behaviour (AU: 2 scores and CH: 3 scores, P<0.01). Analysing the effect of sex both for 86 calves and each breed, it was showed that the TEMP of the heifer and bull calves was equalled (P>0.10). Both of the WW and CWW were influenced by the behaviour of calves (P<0.05), which meant that the more excitable calves had higher WW and CWW. Positive, weak correlation coefficients were calculated among the TEMP, the WW and the CWW (rrank=0.28 and rrank=0.31; P<0.01). By their results it was concluded that in young age not only the performance but also the behaviour of calves are determined by the calf rearing ability of suckling cow.

Annual Water Temperature

The paper considers changes in temperature regime of rivers flowing northerner than 60th latitude. The investigation bases on data about average monthly water temperatures from 90 hydrological gages for the period 1960-2012. Annual water temperatures for this period were calculated according to the generally accepted method as average monthly temperature from May to September and according to the proposed in this paper calculation method for the entire period with positive water temperatures. It is shown that the calculation of annual water temperatures only from the average monthly temperatures from May to October, underestimates annual water temperature. The paper estimates changes in the average annual water temperatures calculated by both methods over the period 1991–2012 compared to 1961-1990 These periods cover intensive climate change, as well as the time after the construction of the largest hydroelectric power stations. Statistical analyzes of the obtained series for trends (according to the Spearman rank correlation test) and series uniformity disturbances (Mann-Whitney U-test) were carried out. A significant increase in the average annual water temperatures in rivers on most rivers of the Russian Arctic is shown. The greatest changes are observed in the territories of Yakutia. Significant changes are also noted on the Kola Peninsula. At the same time, the magnitude of the changes depends on various hydrological characteristics of the basin. Significant changes to date have occurred in less than 50% of the investigated rivers.

Background Glycated albumin reflects 2–3-week glycaemic controls, and in addition to glycated haemoglobin, it has been used as a glycaemic control indicator. We presumed that glycated albumin also has seasonal variations and is related to temperature, similar to glycated haemoglobin. Methods The subjects were diabetic outpatients from April 2007 to March 2013. This resulted in the enrolment of 2246 subjects and the collection of a total of 53,968 measurements. Mean glycated haemoglobin, glycated albumin, and plasma glucose were calculated for each month over six years. The associations of the measures with each other and the average temperature for each month in Tokyo were assessed using Spearman rank correlation coefficients. Results Plasma glucose was highest in January and lowest in May. Glycated haemoglobin was highest in March and lowest in September. Glycated albumin was highest in May and lowest in December. Glycated albumin tended to have a disjunction with plasma glucose in winter. Glycated haemoglobin had seasonal variation, but glycated albumin did not. Plasma glucose and glycated haemoglobin showed significant negative correlations with temperature (rs = −0.359, P < 0.001, rs = −0.449, P < 0.001, respectively), but glycated albumin did not. However, glycated albumin was inter-correlated with plasma glucose (rs = 0.396, P < 0.001) and glycated haemoglobin (rs = 0.685, P < 0.001), and glycated haemoglobin was inter-correlated with plasma glucose (rs = 0.465, P < 0.001). Conclusion Glycated albumin and glycated haemoglobin showed different seasonal variations from each other over the six-year study period. Thus, further studies to identify factors that contribute to glycated albumin are needed.

The purpose of this paper is to presents results from two empirical surveys concerning selected factors which can be connected to customer orientation, performance and competitiveness of firms. The purpose of the surveys was also to reveal potential differences between sectors arising from not only the different influences of internal but as well as external environment. A survey instrument was developed to analyse the relationship between several variables measuring customer orientation of surveyed firms and between these factors and level of financial performance. Several statistical methods were applied to analyse the data, specifically descriptive statistics (means and standard deviations), one-way analysis of variance (ANOVA) with Bonferroni post-hoc test using financial performance for clustering firms and for assessment of potential differences of customer orientation criteria evaluation and Spearman rank correlation coefficients to assess the linear bivariate relationship between customer orientation variables. The results of ANOVA show that only the innovativeness is distinctive distinguishing criteria in conformity with the indicators of financial prosperity and that there are some differences between companies from two groups of sectors within the managers’ perception of customer orientation criteria performance.

COVID-19 is spreading rapidly worldwide and various factors of it have to be analysed. We analyze the effect of climatic parameters (Average Temperature (AT), Atmospheric Pressure (AP), Relative Humidity (RH), Solar Radiation (SR) and Wind Speed (WS)) on the COVID-19 epidemic during 25 March 2020 to 15 June 2020 in most affected states of India i.e. Maharashtra, Delhi and Tamilnadu. We quantitatively establish the correlation between these parameters by using Kendall & Spearman rank correlation test. The results indicate that the positive cases are highly correlated with the AT (r^2 >0.6,p<0.001) in Delhi where as a moderate correlation ( r^2<0.6,p<0.001) has been estimated for Maharashtra and Tamilnadu. Similarly, an intermediate range of correlation coefficient has been observed for other climatic parameters. The range of climatic parameters have been found corresponding to maximum number of cases results as AT (25~40 0 C), RH (40~70%), AT (740~965 mmHg), SR (200-250 W/mt2) and WS (.5~14 m/sec). Time series analysis depicts that the positive cases and mortality are increasing rapidly. COVID-19 epidemic peak is predicted and would be appearing October 2020 using SIR model for capital of India (New Delhi). The outcomes of this study will be helpful for the containment of COVID-19 worldwide.

AbstractObjectiveTo evaluate the relative validity of a food frequency questionnaire (FFQ) for assessing nutrient intakes in 6-month-old infants.Design and settingThe FFQ was developed to assess the diets of infants born to women in the Southampton Women’s Survey (SWS), a population-based survey of young women and their offspring. The energy and nutrient intakes obtained from an interviewer-administered FFQ were compared with those obtained from a 4-day weighed diary.Subjects and methodsA sub-sample of 50 infants aged 6 months from the SWS had their diets assessed by both methods. The FFQ recorded the frequencies and amounts of milks, baby foods, regular foods and drinks consumed by the infants over the previous seven days. The diaries recorded the weights of all foods and drinks consumed by the infants on four separate days within 15 days following FFQ completion.ResultsSpearman rank correlation coefficients for intakes of energy, macronutrients and 18 micronutrients, determined by the two methods, ranged from r = 0·39 to 0·86; adjustment for energy intake tended to increase the correlation coefficients, range ra = 0·55 to 0·89. Bland–Altman statistics showed that mean differences between methods were in the range of −12·5 % to +12·5 % except for vitamin B12 (−18·9 %).ConclusionAlthough there were differences in absolute energy and nutrient intakes between methods, Spearman rank correlation coefficients indicated reasonable agreement in the ranking of intakes. The interviewer-administered FFQ is a useful tool for assessing energy and nutrient intakes of healthy infants aged about 6 months.

Purpose:This study assessed test-retest reliability of an interviewer-administered trail survey.Methods:An intercept survey was conducted with adults using 2 paved trails in Indiana and South Carolina (N = 295; mean age = 46.9 ± 18 y). The survey included items on frequency and duration of trail use for recreation and transportation, other patterns of trail use, and sociodemographic characteristics. Fifty-five adults completed the survey twice (2−16 d apart; mean = 7.4 ± 2.6 d). Test-retest reliability was assessed with Spearman rank correlation coefficients, Kappa coefficients, and percent agreement.Results:Kappa coefficients and percent agreement for 9 categorical items ranged from 0.65 to 0.96 and from 64.0% to 98.2%, respectively. Among these items, the lowest Kappas were found for perceived safety (0.65) and reported duration of visits for recreational purposes (0.67). Spearman rank correlation coefficients for travel distance to and on the trail and frequency of trail use during the past 7 days and past 4 weeks ranged from 0.62 to 0.93.Conclusion:Though further assessments of this survey with different populations and types of trails may be warranted, its overall high reliability indicates it can be used by researchers and practitioners in its current form.
