The aim of the study was to monitor the virulence of Puccinia graminis Pers. f. sp. tritici in the North Caucasus.  The objectives of the study were to collect P. graminis infectious material from sown winter wheat varieties and evaluate the long-term dynamics of the pathogen virulence in the North Caucasus region in 2014-2019. As a result, an analysis of the virulence of the stem rust pathogen population of wheat collected in Krasnodar, Stavropol Territories, and Rostov Region was carried out. 81 mono-empty mushroom isolates were isolated and differentiated.  The genes Sr5, Sr31, Sr38 were characterized by high efficiency.  On the lines with the genes Sr7b, Sr8b, Sr9f, Sr9g, Sr10, Sr11, Sr12, Sr13, Sr14, Sr21, Sr22, Sr23, Sr26, Sr29, Sr32, Sr33, S35, Sr37, SrDp2, SrWLD, a variation in the virulence frequencies of P. graminis was observed.  Significant changes (in the direction of increasing occurrence) in the North Caucasian population 2014-2019  the pathogen was noted in the frequency of clones virulent to wheat lines with resistance genes Sr11, Sr21, Sr22, Sr26, Sr32, Sr33. A decrease in the frequency of clones virulent to Sr8b, Sr9g, Sr10, Sr12, Sr14, Sr35. At approximately the same level, the occurrence of clones virulent to the genes Sr6, Sr7a, Sr8а, Sr9a, Sr9b, Sr9d, Sr9e, Sr13, Sr15, Sr16, Sr17, Sr19, Sr20, Sr24, Sr25, Sr27, Sr30, Sr36, Sr39, Sr40, Sr44, SrGt, SrTmp. Effective genes that have shown their resistance to P. graminis in the seedling phase are proposed for use in breeding in southern Russia to create new varieties of wheat.

Abstract. Although the temporal changes of aerosol properties have been widely investigated, the majority focused on the averaged condition without much emphasis on the extremes. However, the latter can be more important in terms of human health and climate change. This study uses a previously validated, quality-controlled visibility dataset to investigate the long-term trends of extreme surface aerosol extinction coefficient (AEC) over China, and compare them with the median trends. Two methods are used to independently evaluate the trends, which arrive at consistent results. The sign of extreme and median trends are generally coherent, whereas their magnitudes show distinct spatial and temporal differences. In the 1980s, an overall positive trend is found throughout China with the extreme trend exceeding the mean trend, except for Northwest China and the North China Plain. In the 1990s, AEC over Northeast and Northwest China starts to decline while the rest of the country still exhibits an increase. The extreme trends continue to dominate in the south while it yields to the mean trend in the north. After year 2000, the extreme trend becomes weaker than the mean trend overall in terms of both the magnitude and significance level. The annual trend can be primarily attributed to winter and fall trends. The results suggest that the decadal changes of pollution in China may be governed by different mechanisms. Synoptic conditions that often result in extreme air quality changes might dominate in the 1980s, whereas emission increase might be the main factor for the 2000s.

Lemon growing areas in the north of Argentina have industries that produce concentrated juice, peel and essential oil and generate a significant amount of liquid and solid waste as lemon pulp. In Argentina, despite the potential applications that the pulp has as animal feed and human and industrial raw material, only 10% is used for these purposes and the rest is discarded into the environment causing many ecological and economic problems. There is little information in the literature on biotechnologies for the treatment of this industrial waste. This paper shows that lemon pulp is a suitable substrate to be treated by anaerobic digestion. We obtained 86 and 92% reduction of chemical oxygen demand in a digester with a semi-continuous feed and retention time of 10 and 20 days respectively and a productivity of 0.406 g CH4/g VS h. Comparative tests showed that pre-digesting the pulp improved the process of digestion and increased biogas generation by 20%.

Abstract. The Faroe Bank Channel is the deepest passage across the Greenland-Scotland Ridge (GSR), and through it, there is a continuous deep flow of cold and dense water passing from the Arctic Mediterranean into the North Atlantic and further to the rest of the World oceans. This FBC-overflow is part of the Atlantic Meridional Overturning Circulation (AMOC), which has recently been suggested to have weakened. From November 1995 to May 2015, the FBC-overflow has been monitored by a continuous ADCP (Acoustic Doppler Current Profiler) mooring, which has been deployed in the middle of this narrow channel. Combined with regular hydrography cruises and several short-term mooring experiments, this allows us to construct time series of volume transport and to follow changes in the hydrographic properties and density of the FBC-overflow. The mean kinematic overflow, derived from the velocity field solely, was found to be (2.2 ± 0.2) Sv (1 Sv = 106 m3 s−1) with a slight, but not statistically significant, positive trend. The coldest part, and probably the bulk, of the FBC-overflow warmed by a bit more than 0.1 °C, especially after 2002. This warming was, however, accompanied by increasing salinities, which seem to have compensated for the temperature-induced density decrease. Thus, the FBC-overflow has remained stable in volume transport as well as density during the two decades from 1995 to 2015. This is consistent with reported observations from the other main overflow branch, the Denmark Strait overflow, and the three Atlantic inflow branches to the Arctic Mediterranean that feed the overflows. If the AMOC has weakened during the last two decades, it is not likely to have been due to its northernmost extension – the exchanges across the Greenland-Scotland Ridge.

Abstract. Sea ice export through Baffin Bay plays a vital role in modulating the meridional overturning process in the downstream Labrador Sea. In this study, satellite-derived sea ice products are explored to obtain the sea ice flux (SIF) through three passages (referred to as A, B, and C for the north, middle, and south passages, respectively) of Baffin Bay. Over the period 1988–2015, the average annual (October–September) sea ice area export is 555 × 103 km2, 642 × 103 km2, and 551 × 103 km2 through passages A, B, and C, respectively. These amounts are less than that observed through the Fram Strait (FS, 707 × 103 km2). Clear increasing trends in annual sea ice export on the order of 53.1 × 103 km2/de and 43.2 × 103 km2/de are identified at passages A and B, respectively. The trend at the south passage (C), however, is slightly negative (−13.3 × 103 km2/de). The positive trends in annual SIF at A and B are primarily attributable to the increase during winter months, which is triggered by the accelerated sea ice motion (SIM) and partly compensated by the reduced sea ice concentration (SIC). During the summer months, the sea ice export through each Baffin Bay passage usually presents a negative trend, primarily because of the decline in SIM and it is further enhanced by a dramatic decrease in SIC. A significant positive trend in the net SIF (i.e. net ice inflow) is found for between the passages A (or B) and C at 54.5 (or 64.2) × 103 km2/de. Therefore, Baffin Bay may have presented a greater convergence of ice. Overall, the connection between Baffin Bay sea ice export and the North Atlantic Oscillation (NAO) is tenuous, although the correlation is sensitive to variations in the selected time period. In contrast, the association with the cross-gate sea level pressure difference (SLPD) is robust in Baffin Bay (R = 0.69–0.71 depending on the passages), but relatively weaker compared with that in the FS (R = 0.74). Baffin Bay is bounded by Baffin Island to the west and Greenland to the east, thus, sea ice drift is not converted to the free state observed in the FS.

History Of

The article is devoted to studying Russian Bulgarians living in the Urals in the 1940s with the help of archive materials of the Chelyabinsk and Sverdlovsk regions as well as Perm Krai. During the Great Patriotic War the USS Rcitizens of Bulgarian origin, like many other peoples, were subject to repressions which meant enrollment in labour army and deporting every single Bulgarian of the Crimea. As a result of the semeasures, a significant number of Bulgarians were moved to the territory of the modern Urals. The deported Bulgarians settled in areas of logging (forest exploitation) in the north of Molotov and Sverdlovsk regions, and members of the labour army were employed in the trust organization «Chelyabmetallurgstroi». The Bulgarians were deported along with other peoples of the Crimea. They did not form compact settlement in the new areas but managed to preserve their traditional culture. Some families were even able to organize permanent lodging in the Urals, pursue a career and contribute to the development of the region. The author is convinced that the judicial legal documents kept in archives as well as field trip research results may serve as a significant but not sufficiently appreciated source of investigating the history of deporting Russian Bulgarians. The topicality of the sources grew after the year 2020 when the 75-years’ period of storing documents of the year 1945 expired. Autobiographies, biographic information, interrogation protocols enable to obtain a detailed reconstruction of deportation circumstances and the process of enrollment into labour army, and to see these events through the prism of the repressed people themselves. Researching the history of repression, inparticular – repression of the Bulgarians – has revealed how complex and controversial the policy of the soviet state towards certain peoples during the Great Patriotic War was.
