Under the new development pattern of dual circulation economy, reform state-owned enterprises has entered deep water area, and operating environment power grid changed significantly, which a profound impact on capital operation strategy effect enterprises. This paper analyzes characteristics under pattern, constructs incentive restriction index system enterprises, designs restraint mechanism ve...

By 2002, dengue virus serotype 1 (DENV-1) and DENV-2 had circulated for more than a decade in Brazil. In 2002, the introduction of DENV-3 in the state of Bahia produced a massive epidemic and the first cases of dengue hemorrhagic fever. Based on the standardized frequency, timing and location of viral isolations by the state's Central Laboratory, DENV-3 probably entered Bahia through its capita...

The causes of the high pressure ridge at the North American west coast during winter 2013/14, the driest winter of the recent California drought, are examined. The ridge was part of an atmosphere–ocean state that included anomalies, defined relative to a 1979–2014 mean, of circulation across the Northern Hemisphere, warm sea surface temperatures (SSTs) in the tropical western and northeastern P...

[1] Because of its relevance for the global climate the Atlantic meridional overturning circulation (AMOC) has been a major research focus for many years. Yet the question of which physical mechanisms ultimately drive the AMOC, in the sense of providing its energy supply, remains a matter of controversy. Here we review both observational data and model results concerning the two main candidates...

BACKGROUND The Fontan circulation is a palliation for patients with a functionally univentricular heart. It is characterized by gradual attrition over time. An increase in pulmonary vascular resistance could be a key factor in the long-term failure of the Fontan circulation. In this study we aimed to identify pulmonary vascular remodeling in patients with a Fontan circulation. METHODS Pulmona...

Since 2007 a large decline in Arctic sea ice has been observed. The large-scale atmospheric circulation response to this decline is investigated in ERA-Interim reanalyses and HadGEM3 climate model experiments. In winter, post-2007 observed circulation anomalies over the Arctic, North Atlantic and Eurasia are small compared to interannual variability. In summer, the post-2007 observed circulatio...

Abstract This paper attempts to enhance our understanding of the causes Atlantic multidecadal variability (AMV). Following literature, we define AMV as SST averaged over North basin, linearly detrended and low-pass filtered. There is an ongoing debate about drivers AMV, which include internal generated from ocean or atmosphere (or both) external radiative forcing. We test role these factors in ...

This study investigates how anthropogenic aerosols, alone or in conjunction with radiatively active gases, affect the tropical circulation with an atmosphere/mixed layer–ocean general circulation model. Aerosolinduced cooling gives rise to a substantial increase in the overall strength of the tropical circulation, a robust outcome consistent with a thermodynamical scaling argument. Owing to the...

1. introduction heavy snow hazards, although have less frequency in comparison with extreme weather events such as freezing, but are major hazards in midlatitudes (smith, 2009, 196). heavy snow damages manmade structures, crops, casualties, even between urban and rural ways of blocking.(briant. 69, 2005. ohara et al, 2009, 1611). various definitions have been offered for heavy snow, those are c...

while blunt trauma of the head and neck are a common pattern of injury, significant problems related to the prompt diagnosis and optimal management of traumatic artery injuries have been reported in the literature. while patients with major artery injuries might develop hemorrhagic shock very rapidly, patients with blunt cerebrovascular injuries (bcvi) can present asymptomatic, but complication...
