桃源水库蓄水对乌长高速桥梁工程影响评价

乌长高速跨桃源水库库区段位于桃源河大桥至杉里大桥库岸坡及河床段,桥梁工程多处于校核洪水位以下,本文通过收集前期勘察资料,主要运用了地质调查、两段法、十因素评价标准和稳定性分析计算进行评价论证,从而得出,8座桥梁工程中的38个桥墩处于塌岸影响区以内,水库蓄水对其影响大,其余桥墩处于塌岸影响区以外,受蓄水影响较小。提出了加强对受蓄水影响桥基进行塌岸防护,加强水库运行期库岸边坡观测、巡视和巡查工作的意见和建议,可以为乌长高速下步工作提供依据。

回族里画壶艺术大师马少宣

著名文学家邓友梅先生一九八三年写的著名小说《烟壶》,曾轰动海内外。这本书的一开头,便有一首诗介绍二十世纪初北京一带的里画壶名画师。这首诗写道:“登堂入室马少宣,雅俗共赏叶仲三,阳春白雪周乐元,文武全才乌长安。”写小说免不了虚构,这个乌长安便是虚构的。而其他三位,都确有其人,也确实是名画师。这三位中,马少宣先生,是回族穆斯林。

Potential Role of Feldspathic Sandstone as a Natural Water Retaining Agent in Mu Us Sandy Land,Northwest China

This paper analyzed the water-retention mechanism of feldspathic sandstone （fine-（〈 1 mm diam.） and gravel-sized （2-3 cm diam.） in Mu Us Sandy Land, Northwest China. The objective of this study is to study the effect of feldspathic sandstone amendment on water retention in sandy land. The results showed that as the proportion of fine feldspathic sandstone in the sandy land soil increased, the soil texture changed from sand to silt loam, the capillary po- rosity gradually increased from 26.3% to 44.9%, and the soil saturated hydraulic conductivity decreased from 7.10 ram/rain to 0.07 mm/min. Feldspathic sandstone gravel formed micro-reservoirs in the sandy land soil, playing the role of a ＇water absorbent＇ and ＇water retaining agent＇ in sandy land. Amendment with feldspathic sandstone can increase water retention in the arable layer of sandy land by 67%. This study provides a theoretical basis for the amelioration of sandy land on a large scale. It can be concluded that amendment with feldspathic sandstone can improve the physical properties of sandy land soil and increase soil water retention.

Ecological Safe Growing of Chickpea in the Area of Steppe of Ukraine

This work is devoted to developing of the ecologically safe technology of chickpea cultivation by using microbial biopreparations, based on the effective heterotrophic （nodulating, growth-promoting and phosphate mobilizing bacteria, and microorganisms-antagonists of the phytopathogenes） and phototrophic microorganisms （cyanobacteria）. These preparations were used for pre-sowing treatment of seeds and for treatment of the plants in the vegetation period for optimization of symbiotic nitrogen fixation and growing of ecologically safe production （without application of mineral fertilizers） in the steppe non-irrigated areas of Ukraine.

Images of the Future from the Past： The Metabolists and the Utopian Planning of the 1960s

During the 1960s, many changes reshaped the economy, the society and the arts. The Cold War, the Space Race, the construction of a new middle class in most western societies led by the postwar economic prosperity with unprecedented urban growth followed by severe environmental problems fostered the design of spectacular urban utopian cities and mega-architectures. In those years, Japan was the source of highly influential bold and visionary urban and architectural ideas which relied on advanced technology. These ideas were conceived on the thought that cities could be seen as gigantic but impermanent entities able to transform itself according to an organic process of adaptation of its elementary components. This paper briefly revisits and critically discusses the legacy of the iconic mega-strnctural projects of Japanese Metabolist Movement and other visionary architects and planners of the 1960s, such as Paolo Soleri, Buckminster Fuller, Archigram. It attempts to enlighten the continuity with contemporary innovative and experimental urban models and ideas for the society and the city of the future, such as the Smart Cities, Eco-Cities, Green Urbanism, whose design is led by concerns related to climate change, the necessity of energy efficiency, the improvement of urban landscape and the valorization of depleted natural resources.

Finance Sector in Eurasian Economies During and After the Global Crisis in 2008

As in the other countries around the world, banking systems in Eurasian economies, comprised of Armenia, Azerbaijan, Georgia, Kazakhstan, the Kyrgyz Republic, Tajikistan, Turkmenistan and Uzbekistan, were adversely affected by the 2008 global crisis. A common challenge across most economies is to revive private-sector credit growth. Compared with the high increases of 80 percent in the period immediately prior to the crisis, credit growth has slowed sharply and even turned negative in real terms in a number of economies. Governments in many countries have taken measures to address banking sector stress. The measures for restoring credit growth and thus a high economic growth will be discussed in a part of our work. In the short run, such measures include aiding banks to repair balance sheets and also providing liquidity. In the medium term, measures should promote de-dollarization and the development of local debt markets.

Chronic toxicity of both raw and processed Polygoni Multiflori Radix on rats

Recently, adverse effects of Polygoni Multiflori Radix（PMR） and Polygoni Multiflori Radix Praeparata（PMRP） have attracted intensive attention worldwide. These adverse effects most occurred in cases with high dose of prolonged medication course. Liver is usually the target organ of these adverse effects. In the present research, we performed in vivo chronic toxicity study and aimed to evaluate relationships between major constituents of water extractions and total anthraquinone of PMR and PMRP and chronic toxicity. SD rats of both sexes were given water extractions as well as total anthraquinone of PMR and PMRP for 12 weeks. We evaluated basic biochemical indexes, conducted microscopic observations of main organs and assessed early indicators of liver and renal fibrosis. Simvastatin, with hypertriglyceridemia and hypercholesterolemia as its main therapeutic areas, was investigated in our study. Component-toxicity relationships were also discussed. Five male rats died in our study, while all female rats survived, suggesting that some gender differences might be involved. Body weight was significantly changed, and basic biochemical indexes were sporadically occurred during the research. Pathological examinations on liver and kidney showed slight alternations after 12 weeks without dose-dependent relationship. Increase in serum laminin（LN） was observed in almost all male rats, indicating that the risks of liver or kidney fibrosis still existed, especially for males, although no fibrosis was found in the pathological examination of liver and kidney. No major and severe adverse effects were observed after 12 weeks of administration of PMR and PMRP. Regular safety monitoring is still necessary during medication in order to prevent possible risks.

Homogenization of Elliptic Problems with Quadratic Growth and Nonhomogenous Robin Conditions in Perforated Domains

This paper deals with the homogenization of a class of nonlinear elliptic problems with quadratic growth in a periodically perforated domain. The authors prescribe a Dirichlet condition on the exterior boundary and a nonhomogeneous nonlinear Robin condition on the boundary of the holes. The main difficulty, when passing to the limit, is that the solution of the problems converges neither strongly in L^2(Ω) nor almost everywhere in Ω. A new convergence result involving nonlinear functions provides suitable weak convergence results which permit passing to the limit without using any extension operator.Consequently, using a corrector result proved in [Chourabi, I. and Donato, P., Homogenization and correctors of a class of elliptic problems in perforated domains, Asymptotic Analysis, 92(1), 2015, 1–43, DOI: 10.3233/ASY-151288], the authors describe the limit problem, presenting a limit nonlinearity which is different for the two cases, that of a Neumann datum with a nonzero average and with a zero average.
