The article is devoted to the urgent problem of studying the features of the properties of poorly studied oils at great depths (more than 4,500 m), the need for development of which is caused by the continuing decline in oil production in traditional oil producing provinces. The analysis of the spatial distribution of reserves across the continents and countries of deep-seated oils and changes in their physico-chemical properties and the occurrence conditions, which made it possible to identify their main features. The studies used information on 21067 oil samples from 167 oil-bearing basins of the world, obtained from the database on the physicochemical properties of oils. The features of the physicochemical properties of deep-seated oils have been established, which are manifested in a decrease in the density and viscosity of oils, in a decrease in the content of sulfur and asphalt-resinous substances, and in an increase in the content of light fractions and oil gas in comparison with oils of small and medium depths.

Ceratitis Cosyra

The mango fruit fly (Ceratitis cosyra Walker) is the major pest of economic importance and which restricts mango exports from infested production areas in the SADC region. The effect of three pruning techniques, box/rectangle, spherical/round and the central leader, on assessing spatial distribution of fruit fly populations in high density mango production were investigated at Chiredzi Research station (21°01’S, 31°33’E) from 2010 to 2013. Results showed a significant rise in the number of adult fly catches among pruning techniques as from July to December (p< 0.05). Traps baited with Malathion 25% WP with molasses as an attractant were used to trap the flies. Results from all treatments indicated a significant rise in mean adult fruit fly catches from the months of July to December. It can be concluded that spatial distribution of the mango fruit fly is influenced by the fruiting and ripening patterns of mango.

Aerosol Optical Depth (AOD) is of great value for studying air mass and its changes. In this paper, we studied the spatial-temporal changes of AOD and its driving factors based on spatial autocorrelation model, gravity model and multiple regression analysis in Jiangsu Province from 2007 to 2016. The results showed that in terms of spatial distribution, the southern AOD value is higher, and the high-value aggregation areas are significant, while the northern AOD value is lower, but the low-value aggregation areas constantly change. The AOD gravity centers showed a clear point-like aggregation. In terms of temporal changes, the overall AOD in Jiangsu Province increased year by year in fluctuation. In terms of driving factors, the total amount of vehicles, precipitation and temperature are important factors for the growth of AOD.
