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.

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.

Indonesia is the most generous country in the world. This is evident from the World Giving Index created by the Charities Aid Foundation which has placed Indonesia in the number one position in the world in 2018. There is an increase compared to the previous year, where Indonesia was in second place after Myanmar. The main indicators are the level of donating money, helping foreigners, and participating in volunteer activities. On the other hand, the World Bank in 2018 placed Indonesia in the sixteenth position based on GDP Current USD and the eighth position based on GDP PPP Current USD. This proves that income is not the main thing that encourages someone to give alms. However, it is still uncertain whether income and level of alms correlate with each other. Jones and Posnett (1991) revealed that an increase in the behavior of giving alms is not in line with an increase in household income. On the other hand, there is a significant positive relationship between income and a person's level of alms (Arshad, 2016). The two types of research mentioned (Jones and Posnett, 1991; Arshad, 2016) conducted testing at the micro level. Therefore, this research will concentrate more on the macro level. Pharoah and Tanner (1997) explain that people who consider religion important in their lives tend to give more. This study uses a quantitative approach to test the correlation between the World Giving Index and GDP using the Spearman rank correlation test. The Spearman rank correlation test measures the correlation between two random variables based on ranking order. The author has found that there is no correlation between high income and the desire to give alms. This research can be used as a reference for the Indonesian government to reduce inequality and poverty in the country by realizing the potential of alms in Indonesia.

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.
