Calculation of the aggregated "consensus" industrial production index has made it possible to date cyclical turning points and to measure the depth and length of the main industrial recessions in Russian Empire/USSR/Russia for the last century and a half. The most important causes of all these recessions are described. The cyclical volatility of Soviet/Russian industry is compared to that of American one.

The present study intends to reveal spatial regularities between non-immigrant and immigrant numbers in two different ways. First, it questions the existence of those regularities when spatial scales get finer. Second, it uses pooled data over four population censuses covering the period from 1991 to 2006, which enabled us to apply appropriate techniques to remove those unobserved fixed effects so that the estimations would accurately identify the linkage between local immigrant and non-immigrant numbers. The results provide evidence about the existence of negative spatial regularities between non-immigrant and immigrant numbers in Canada at national scale.

Low-traumatic technology of grain separation from an ear is developed. It consists in influence of an air jet on an ear.It leads to rolling of an ear on a surface of the threshing device concave and causes its partial abrasion which is followed by grains separation. Process of wheat ears low-traumatic threshing in the experimental device yields satisfactory results, provides reduces grain endosperm damage on 10-12% in comparison with traditional technology. Germ of grain damage decreases by 5%.Crushing of grain made no more than 0,5%. Use of the developed technology of the low-traumatic threshing will allow to reduce grain damage of cereal crops in case of the harvesting. It is important by cereal breeding.

This paper aims to document expansions and recessions characteristics for 17 states of Mexico over the period 1993-2006 by using a classical business cycle approach. We use the manufacturing production index for each state as the business cycle indicator since it is the only output measure available on a monthly basis. According to this approach, we analyse asymmetries in mean, volatility and duration as well as synchronisation over the business cycle regimes (expansions and recessions) for each case. Our results indicate that recessions are less persistent and more volatile (in general) than expansions in most Mexican states; yet, there is no clear cut evidence on mean asymmetries. In turn, there seems to be strong links between the business cycle regimes within the Northern and Central regions of the country and between states with similar industrialisation patterns, although it is difficult to claim that a national business cycle exists.

The article discusses the issues of territorial patterns in the implementation of precision farming technologies, which are insufficiently studied and constitute a significant scientific problem. The purpose of the study is to identify the territorial patterns of the introduction of precision farming technologies in conjunction with the indicators of agricultural development in the regions. The number of applied precision farming technologies was clarified, 37 regions took part in the study, 24 of them provided information on the application of these technologies. The results of correlation of regional development indicators (12 indicators in three blocks) and the amount of equipment with precision farming elements are presented. The greatest positive correlation is observed between the introduction of precision farming technologies and the agricultural production index at comparable prices (0.51) and the level of subsidies (0.37). The greatest negative correlation is observed between the introduction of these technologies and the change in the registered unemployment rate (-0.3). Based on the results obtained, it can be assumed that in regions with high values of agricultural production growth and subsidies, precision farming technologies will be most intensively introduced.
