Thermal infrared satellite imagery is increasingly utilized in permafrost *** useful application of the land surface temperature(LST)products is classification and mapping of landscapes in permafrost regions,as LST values can help differentiate between frozen and unfrozen *** article describes a new approach to the use of *** essence of the new approach lies in the fact that in the territory where it is impossible to determine(indicate)the state of the underlying ground according to the same morphological characteristics(relief,vegetation,soil composition,etc.),the LST parameter,which reflects the thermal state of the landscape,allows as an additional criterion(indicator)identify frozen/un-frozen *** this work,using the above approach,a map has been compiled,which shows the permafrost natural-territorial complexes of the Elkon Massif,Eastern Siberia,including topography,slope aspect,slope angle,vegetation,snow cover and *** map provides a more detailed and updated description of permafrost distribution in the study area.

全球经济发展放缓,国际政治经济形势风云变幻,一些国家和地区间歇性地贸易保护主义抬头。如今,美中贸易摩擦不断升级,美西方对俄制裁的清单不断扩大,从政治、经济、文化艺术,到一树一猫……。在这种错综复杂的政治经济环境下,中国和俄罗斯都面临着巨大的挑战。同时,客观上也为中俄两国深化双边合作提供了机遇。中俄两国更加清楚地认识到,两国需要携手合作,共克时艰。中俄两国在农业经贸领域合作潜力巨大。两国在生产要素上具有各自的比较优势,在商品结构方面、自然资源、农业技术与创新禀赋等要素上不仅具有比较优势,还具有互补性。理论上两国之间具有合作基础。本课题研究的目的是探讨促进中俄两国农业经贸合作可持续发展的对策。论文采用文献研究法、比较研究法、实证分析法对中俄两国农业经贸合作发展的问题与对策进行研究。论文阐述了国际分工理论、绝对优势理论、比较优势理论、要素禀赋理论,为研究奠定坚实的理论依据,搭建最基本的研究基础。回顾了中俄两国农业经贸合作的发展历程与成就,对两国农业经贸合作比较优势和互补性进行了分析,剖析了影响两国农业经贸合作的问题,分析借鉴其他国家间农业经贸合作经验与启示,提出促进中俄农业经贸合作可持续发展的对策建议。对本课题进行的研究,不仅具有理论意义,还具有实践价值。厘清中俄双方的优势劣势,为两国农业经贸合作找出新方向与新的增长点,这在一定程度上有助于弥补该问题的现有研究多局限于国家层面分析之不足,有助于形成更有针对性的建议,为中俄两国农业经贸合作的健康发展提供理论参考。实践上开阔了中俄农业经贸合作的研究视野,为两国政府创新农业经贸合作模式、延伸合作领域、制定共同认可的贸易规则提供了新思路。

Sparing Treatment of Thoracic and Abdominal Aortic Aneurysms

引用

Health 2018年第4期10卷 458-466页

作者： V. P. Krylov D. E. Shevtsov G. A. Popel A. S. Zhigalkovich V. N. Gaiduk L. I. Reut A. L. Smolyakov L. G. shestakova N. V. Mankevich Belarusian Association of Physicians Republican Research and Practical Centre “Cardiology” Minsk Belarus

A comparison of results of sparing treatment obtained at 2, 4 and 6 years of follow-up in subjects with descending aortic atherosclerotic aneurysms (DAAs), and during the period between 1.5 and 8.9 years in subjects with dissecting thoracoabdominal aortic aneurysms (DTAAs) has been made. All subjects received conservative treatment to maintain optimal levels of BP, cholesterol and LDL cholesterol, as well as to reduce oxidative and inflammatory processes in aorta, strengthen aortic walls and stabilize the course of the disease. Rapid negative changes (diameter increased by more than 5 mm within a 6-month period) and the absence of contraindications for surgery prompted us to perform open or endovascular aortic repair. Available data suggest that both DAAs and TAAs are comorbidities, which at any time can abruptly terminate patient’s life, and operative treatment guarantees no safety from ruptures. When using sparing treatment of DAA, survival rates were 90.1% at 2 years, 76.8% at 4 years, and 59.4% at 6 years, with uniform survival increment mainly due to comorbidity. Survival rate seen in TAA group (81.8%) was more acceptable due to a younger age of patients.
