Immigration policy and integration of migrants in the Kingdom of Denmark at the beginning of the XXI century

Denmark upholds high standards of human rights as long as the interests of its citizens are concerned but erects barriers for migrants of a different cultural background who might threaten the security of the national community. The Danish tradition of liberalism, humanism and the welfare state coexists with one of Europe’s most restrictive policies towards third-country immigrants. The article traces the evolution of management approaches to developing the immigration policy and integrating foreign cultural migrants in Denmark. It describes the value determinants of these changes. Using the neo-institutional methodology, the authors analyse the evolution of the value determinants of Denmark’s immigration policy and look at the national norms and practices of integrating migrants from a different cultural background. A restrictive immigration policy became possible due to a consensus between the main political forces, the left Social Democratic Party and the right Liberal Party Venstre, both willing to keep in check electoral support for the radical right-wing parties (the effect of 'contagion from the right' in Maurice Duverger’s terms). The object of Denmark's restrictive integration policy is migrants from a different cultural background (mainly from Muslim countries). The government takes systematic measures to restrict their access to the country. As to migrant integration, the focus has shifted to 'hard' assimilation of civiс democratic values, benefits linked to employment, and deportation of migrants who have committed crimes

A study of the biohydrometallurgical method for extracting gold from flotation tailings

This paper shows the results of the comparative study of efficiency of gold extraction methods from technogenic flotation tails by agitation cyanidation and biooxidation followed by leaching. A representative sample of flotation tails was taken at gold extraction plant of Altyntau Kokshetau LLP. Experimentally, an increase in the efficiency of leaching gold from flotation tails during preliminary bacterial oxidation was found. By biochemical leaching, 72 % was extracted, which is 7 % more than using expensive sodium peroxide and 10 % more than using the traditional method of cyanidation

Research of biochemical gold recovery method using high-arsenic raw materials

This article contains the results of experiments to recover gold from complex mineral raw materials containing more than 15 % arsenic. Laboratory tests showed that standard cyanidation recovers only 26,4 % of gold into the solution. Additional oxidizing reagents used increase the leaching efficiency and enable to recover more than 40 % of gold during subsequent cyanidation. The efficiency has been established for replacement of cyanide with thiourea and thiosulfate solutions. 79,5 %, i.e. the maximum recovery rate, was found in the experiment with preliminary oxidation with T. Ferrooxidans, a bacterial culture, followed by leaching with a thiourea solution

On the collective monograph “Ethnonational processes in the Arctic: trends, problems, and prospects”

The article represents the review of the collective monograph “Ethnonational processes in the Arctic: trends, problems, and prospects.” The monograph is an original joint work of researchers at Russian research centers specializing in the study of the Arctic. The researchers focus on ethnonational processes in the context of the socio-economic, socio-political, legal, socio-cultural development of the Arctic territories of Russia. The interdisciplinary nature of the research, the full coverage of ethnonational policies and subregions, the depth of the study, the visualization of the material with tables, charts, graphs, maps determines not only the academic but also the comprehensive nature of the monograph under review

Modified Ross operation (literature review)

One of the surgical methods for treating aortic valve pathology is the Ross operation, which was proposed by the British cardiac surgeon D. Ross in 1967. Numerous studies have shown excellent long-term outcomes of this operation. However, in some patients, pulmonary autograft dilatation may occur in the long term. To avoid this complication, technical modifications of this procedure have been proposed. A literature review on modified Ross operation as a prevention of pulmonary autograft dilatation is presented

Pulmonary homograft dysfunction after Ross procedure in adults: a single center experience

The Ross procedure was first proposed by Donald Ross in 1967. Numerous studies show excellent long-term outcomes of the Ross operation. One of its disadvantages is the intervention on two valves due to pulmonary homograft dysfunction.Aim.  To study long-term outcomes of pulmonary homograft use after Ross operation (cumulative incidence of pulmonary homograft dysfunction, freedom from reoperation on pulmonary homograft, long-term survival, predictors of pulmonary homograft dysfunction) using data from one Russian center.Material  and  methods. A retrospective study included patients aged 18 years and older with aortic valve disease who underwent Ross procedure from April 2009 to December 2020 by a single surgeon. The age of the patients was 35 (26-44) years (men, 159 (75%)). Infective endocarditis as a cause of aortic valve pathology was diagnosed in 55 (26%) patients. Bicuspid aortic valve was diagnosed in 131 (62%) patients. The median follow-up period was 79 (26,5102,7) months.Results. Combined interventions were performed in 40 cases (18,9%). The modified Ross procedure was used in 54 (25,5%) cases (intra-aortic — 29, using Dacron tube graft — 25). Inhospital mortality was 0,5%. The 5- and 10-year allcause survival rates were 98,5% and 95,4%, while the 10-year cumulative pulmonary valve reoperation rate and pulmonary homograft dysfunction was 4,6% and 35,2%, respectively. The only factor affecting pulmonary homograft dysfunction was patient age ≤30 years (odds ratio =0,2 with 95% confidence interval: 0,06-0,7; p=0,02).Conclusion. Fresh pulmonary homografts have a low incidence of dysfunction and reintervention after Ross procedure. Young age is the only independent risk factor for pulmonary homograft dysfunction
