The development of agro-industrial complex is important for ensuring national food security and national health.The development of rural areas is subject to the development of agriculture and local infrastructure,as well as the availability of various services.This study selected 15 indicators in 2021 to analyze the employment and development levels in rural areas of 71 regions of the Russian Federation using the analytical grouping method.The results indicated that 20 regions(Group 1)had the highest percentage of rural population(33.10%).The percentage of population engaged in agriculture had the highest value(12.40%)in 31 regions(Group 2).Moreover,20 regions(Group 3)had the highest investments in fixed assets at the expense of municipal budget(11.80 USD/person).Increasing the investments in fixed assets carried out from the budget of the municipality can improve the employment level in rural areas.Then,we used cluster analysis to divide 14 regions of the Volga Federal District in the Russian Federation into 3 clusters.Cluster 1 covered Kirov Region and Republic of Mari El;Cluster 2 included Ulyanovsk Region,Saratov Region,Nizhny Novgorod Region,Perm Territory,Orenburg Region,Chuvash Region,and Republic of Mordovia;and Cluster 3 contained Republic of Tatarstan,Samara Region,Udmurtian Republic,Penza Region,and Republic of Bashkortostan.Results indicated that the 2 regions of Cluster 1 need to increase the availability of resources and natural gas and improve the investment attractiveness of rural areas.The 7 regions of Cluster 2 needed to develop infrastructure,public services,and agricultural production.We found the highest employment level in rural areas,the largest investments in fixed assets at the expense of municipal budget,the largest residential building area per 10,000 persons,and the largest individual residential building area in the 5 regions of Cluster 3.This study makes it possible to draw up a comprehensive regional development program and proves the need for the development of rural areas,which is especially important for the sustainable development of the Russian Federation. 展开更多

Image distortion caused by the angular misalignment of quadrupole magnets in high-energy electron radiography has been studied systematically.We propose that the distortion originates from the coupling of the electron motions in the transverse directions,based on a theoretical analysis and the transfer-matrix method.The relative angular rotation between the second and third magnetic quadrupoles was identified as the main contributor to image distortion.This was verified by both a beam-dynamics simulation and experiments.Different strategies to mitigate this image distortion are also explored,including magnets online tuning,higher beam energy and larger magnification factor.This study provides criteria for designing experiments and paves the way for achieving higher image precision. 展开更多

The political essence of Russian conservatism is to respect the historical tradition and take a development path aligned with Russia's national conditions.Since Putin came to power,Russian conservatism has developed into the mainstream official ideology,becoming the core concept of Russia's current domestic and foreign policies.Russian conservatism is not only the guiding principle of Russia's national foreign policy,but it is also the moral banner of Russia's diplomacy,which reflects its foreign cognition and value system.Under the guidance of conservatism,Russia's foreign policy has distinct offensive features,and Russia has intensified its efforts to counter the liberal international order dominated by the West.After the escalation of the Ukraine crisis,the status of conservatism as Russia's mainstream ideology has been further consolidated,exerting a comprehensive influence on foreign policy.Against the background of extreme sanctions and isolation from the United States and the West,Russia has turned its diplomatic attention to non-Western countries,hoping to build a new international order. 展开更多

The Russian wheat aphid (RWA), Diuraphis noxia (Mordvilko), has become a worldwide cereal pest with its dispersion to over 30 countries in this century. According to the natural history of its occurrence around the world, it is postulated RWA originated from western or central Asia. The aphid dispersed gradually to Europe and northern Africa, but its big jump across the ocean to North America is still a mystery. There are two overwintering strategies in RWA. The anholocyclic biotype, often reproducing earlier and more offsprings than the holocyclic one, has greater impact on crops in South Africa and United States. According to the experiments on its thermal response, RWA could withstand temperatures below -20℃, while temperatures above 30℃ would be harmful to its survival. The preference to colder condition may determine its distribution on the world. RWA has made great damages to cereal crops worldwide. It caused loss in crop yield by directly feeding on plant nutrition and disturbing the plant metabolism. But its status as plant virus transporter is open to question. By now, the aphid is still a serious pest in many countries and its invasion to more countries and areas maybe continues. Therefore, the research on its biological characteristics as well as its dispersion apparently needs to be enhanced in the future. 展开更多

The control measures to this pest were reviewed, emphasizing on natural enemies and plant resistance. First, spring wheat with earlier planting dates had higher yield and could resist RWA infestation to a more extent, while winter wheat with later planting dates could escape infestation of Russian wheat aphid with very few exceptions. So, manipulation of wheat planting dates was suggested in worldwide scale for the aphid control. Second, the natural enemies were considered as the most important factor to reduced the pest status. Introduced and native natural enemies were evaluated for their potential as biological agents in South Africa, United States, and Australia. In South Africa, an introduced parasitoid and a predator were selected for releasing. In the United States, the project on exploring and releasing the natural enemies was unprecedented in biological control history. The endeavor in USA has been proved primarily successful today and will be afterward. The RWA control in Chile was considered most successful, partly because of their introduction of natural enemies before the aphid arrival. The native enemies together with other factors in central Asia and Europe apparently suppressed the aphids to a low level. The screen for resistant wheat was another important research project in fighting with RWA. In South Africa and USA, resistant wheat and barley were bred, and some of them had been put in commercial use for RWA control. The overwhelming mechanisms in resistant wheat varieties were antibiosis, tolerance or their combination. Though chemical insecticide spraying was proved as an effective method for aphid control, more and more research has switched from this method to non chemical control measures as required by IPM. Future research should put more emphasis on augmentation of the natural enemies, revealing the relationship between RWA and agricultural ecosystem and integration of all effective measures. 展开更多

PartⅠ, entitled ' Nabokov’ s Women,' concentrates on the analysis of Nabokov’ s major women identities of different types. My purpose is to demonstrate that in his creation of the women characters, Nabokov’ s political consciousness—mainly his vindication of individual freedom—is unmistakably, although indirectly, exemplified. Due to the different types of women discussed in this study, and also due to the different aspect of his political consciousness that is emphasized in different women identities, this part is subdivided into three chapters. Chapter One, entitled 'Women in the Triangle: Martha and Margot,' focuses on the two women characters in Nabokov’ s early novels. King, Queen, Knave and Laughter in the Dark, aiming to provide an in-depth analysis of the two, and to show that Nabokov has be stowed his special purpose on the creation of Martha and Margot, that is, his condemnation on those who reduce the free and active individual into objects, and such condemnation echoing with Nabokov’ s later direct vindication of individual freedom. Chapter Two, entitled 'The Eternal Feminine:Lolita and Ada,' analyzes the two title characters in Lolita and Ada, or Ardor:A Family Chronicle, illustrating that Lolita is the victim in that her free consciousness is purposefully neglected by the other, man in that case;while Ada enjoys her life totally because she can conduct her free consciousness in her own life. Chapter Three, entitled ' Other Types and Women in His Mind’ s Eye,' deals with Elisabeth, another woman character in Laughter in the Dark, who is a good traditional wife, and Liza, ex-wife of Pnin in Pnin, who is what Nabokov terms as poshlost. In addition, this chapter also provides an examination of Nabokov’ s attitude toward women. Through this analysis, Nabokov’ s Russian Complex is to a degree illustrated. 展开更多

This paper presents the past,present and future status of the Russian VLBI network "Quasar".This network has been developed for at least 20 years by the Institute of Applied Astronomy of the Russian Academy of Sciences(IAA RAS). The equipment installed currently at each "Quasar" station and the facilities for processing observational data are described briefly. The latest results are presented, including the Earth orientation parameters(EOP) determined from the "Quasar" VLBI data and comparison with those from other processing centers. Our future plans to extend the "Quasar" VLB I network to the east and to the west will be carried out by establishing the Ussurijsk station in the Far East and the RussianCuban station in the west. They are considered in the context of the Russian section activity in the GGOS project. The expected improvement of the EOP determination accuracy can be obtained within the future configuration of the "Quasar" network,which is proved by simulation. 展开更多

Phosphorite nodules are widespread in the Kursk complex deposit (Russian platform). Genesis of these nodules has long been a matter of debate, and this has hampered understanding of the mechanism and controls in the formation of the nodules. In this paper, we report the petrographical, mineralogical, and geochemical data of the Lebedinsky phosphorite nodules. Petrographic study reveals complex phosphatic cement resulting in the replacement of apatite minerals around quartz grains. The main mineral composition consists of quartz, phosphate minerals (apatite, francolite mainly), feldspar, iron hydroxides and carbonate minerals. These results, when combined with available data, are used to address the origin of the phosphorite nodules. The nodules are characterized by the universal presence of biogenic and chemical signatures which is phosphorus crown around crystal grains. The structure of the nodules is massive. Their texture is depicted by basaltic cement and concretion, which consists mainly of apatite and its varieties, with general formula: Ca_10 (PO_4, CO_3) 6(F,OH,Cl). Variation of mineralogy appears dependent on geological setting. Microscopic observations of biogenic fossils in Lebedinsky phosphorite favor a chemical and biogenic origin of phosphorites. Weathering has been suggested to be capable of liberating as much as 20 %-35 % P_2O_5 from sedimentary rocks. Previous investigations demonstrate that weathering of the Proterozoic substratum was the main cause in the formation of Fe, Mo, Mn, Pb, Zn, and P in the Russian platform. We therefore suggest that both weathering and biochemical processes have been positive in the formation of the Lebedinsky phosporite nodules. However, whether continental weathering or oceanic bio-chemical processes are more relevant in the phosphorite accumulation remains undetermined. 展开更多

Although Blakiston’s Fish Owl(Bubo blakistoni) is widely treated as a single species,marked differences in the structure of pair duets between continental and insular populations have been documented.However,no study has quantitatively assessed these vocal differences.We obtained 192 duets from 22 pairs of Blakiston’s Fish Owl:15 pairs of B.b.blakistoni from the Japanese island of Hokkaido and the Russian Kuril island of Kunashir,and seven pairs of B.b.doerresi from Primorye on the Russian mainland.This is a sizeable dataset for such a large,retiring,and rare owl.We conducted bioacoustic examinations of 14 vocal parameters using principal component analysis and the Isler criterion to quantitatively test species boundaries within the B.blakistoni complex.We found that the insular populations on Hokkaido and Kunashir emerged as vocally similar to each other but markedly different from the continental populations of B.blakistoni,corresponding closely with presently accepted subspecies limits.Bioacoustic differences in the duets of the insular and continental groups are greater than the pairwise comparisons of territorial vocalisations between other sympatric owl species.Based on the reproductive importance of vocal duets in owl biology,we propose the taxonomic elevation of the continental subspecies to species level as Northern Fish Owl B.doerriesi.Our study corroborates the importance of bioacoustics in ascertaining species boundaries in owls and has important implications for the management of the two newly delimited species,each likely to be assessed as Endangered.Both species should be managed independently to optimise conservation outcomes. 展开更多
