Perspective reinforcing material for fibre concrete
No full textThe different types of wire fiber are considered, advantages of fiber of high-modular wire with heightened bending stiffness are shown. Analysis by volumes of fiber production in the world is carried out. Peculiarities of fiber production at RU P «BMZ» are shown. Recommendations on correlation «wire diameter-fiber length» are given for different types of fiber for prevention of fiber caking at production of fibrous concrete are given

Key actors of German "soft power" in the Baltics
No full textThis article focuses on Germany’s key "soft power" actors promoting the country's interests in the Baltics. The authors analyse the policies of "soft power" aimed to create a positive image of Germany in Lithuania, Latvia, and Estonia. The article examines the activity of German political foundations, research institutions, communities, language centres, and scientific and cultural organisations. It is stressed that Germany makes use of the Baltics' historical familiarity with German traditions in implementing its policy in these countries. The study suggests that German political and educational foundations are major actors of German soft power. It is shown that the development of a multilevel German language learning system incorporating various courses and scholarship programmes is one of the central strategies of German foundations. This strategy uses "High German" as a means to integrate the Baltic audience into the German information space. The German language serves as a basis for popularisation of the German educational system and educational standards, on the one hand, and partnership institutionalisation, cooperation, and integration on the other. It is concluded that, alongside Sweden and Russia, Germany is a major foreign policy player in the Baltics
Prevention of Liver Failure in Extended Hepatic Resection
No full textBackground. Postoperative failure is a major cause of adverse outcomes in extensive liver resection. Post-resection liver failure requires intensive, including extracorporeal, care. Issues in correcting liver failure warrant novel approaches to prevent severe cases.Materials and methods. A retrospective analysis of 228 various-extent liver resections included minor (55.7 %), major (26.8 %) and extended (17.5 %) operations for malignant, benign and parasitic liver lesions. The post-resection liver failure rate has ben graded according to ISGLS.Results and discussion. Postoperative hepatic failure developed in 58 (25.4 %) cases, including 5 of 127 minor (3.9 %) resections, 18 major (29.5 %) and 35 of 40 extended resections (87.5 %). Mild class A liver failures were reported in 12.3 %, and severe classes B and C — in 9.2 % and 3.9 % cases, respectively.CT volumetry in place of the number of resected segments is suggested as a criterion to grade the expected post-resection residual liver, with >70 % defining a minor, 36–70 % — major and 25–35 % — extended expected residual liver.A two-staged extended hepatic resection approach is proposed to reduce postoperative liver failure, with vascular radiology-guided right portal vein embolisation (RPVE) or associating liver partition and portal vein ligation (ALPPS) at stage 1.A comparison of extended hepatic resection outcomes (n = 40) showed a significantly higher rate and severity of liver failure in single- vs. two-staged operations (p < 0.05).Conclusion. Liver failure is a leading cause of death in major and extended hepatic resection. Preoperative CT volumetry allows a more accurate volumetric control of expected post-resection residual liver. Two-staged extended hepatic resection can reliably reduce the rate and severity of postoperative liver failure
