Many noncompact Type I orbifolds satisfy tadpole constraints yet are anomalous. We present a generalization of the anomaly inflow mechanism for some of these cases in six and four dimensions.

With HeartMate II (HMII) implants increasing so has the frequency of device exchange. However, identifying inflow cannula obstruction, pump thrombosis, or outflow obstruction as the mechanism of pump dysfunction can be difficult. Echocardiography, CT angiogram, and cardiac catheterization are not definitive in determining the location of pump failure. Therefore, intraoperative examination is of...

[1] During 2002 and 2003 exceptional inflow events have been registered. In January 2003 a massive inflow of highly saline, cold and extremely oxygen-rich water from the North Sea was recorded at Darss Sill. This event is considered to be the most important inflow since 1993. A coupled model system for the Baltic Sea region, called BALTIMOS, was developed in the frame of DEKLIM/ BALTEX by linki...

The stratification of the atmospheric boundary layer (ABL) is classified in terms of the M-O length and subsequently used to determine the relationship between ABL stability and the fatigue loads of a wind turbine located inside an offshore wind farm. Recorded equivalent fatigue loads, representing blade-bending and tower bottom bending, are combined with the operational statistics from the ins...

Inflow of high-saline water of oceanic origin and diapycnal mixing force the vertical circulation of the Baltic Sea. The inflows of saline water are also enriched with oxygen and therefore the oxygen concentrations of the deep layers of the Baltic are strongly dependent on long-term inflow variations. This paper presents flux calculations for water, salt, nutrients and oxygen from the Arkona Ba...

26 The Mediterranean Sea shows a peculiar anomaly in its nutrient pattern compared to the 27 global ocean, as there is decrease in nutrient concentration from west to east. This 28 feature has been attributed to the anti-estuarine circulation at the Strait of Gibraltar, 29 where an eastward flow of Atlantic nutrient-poor surface waters is compensated by a 30 westward counter-current of Mediterr...

The Florida (USA) Everglades ecosystem has been impacted due to increased loading of nutrients, in particular phosphorus (P), primarily from adjacent agricultural areas. Consequently, restoration measures involve the establishment of stormwater treatment areas (STAs) comprising a series of constructed wetlands. A series of mesocosms were established at the inflow of the Everglades Nutrient Remo...

For verification of spatial distribution of phosphorous retention capacity in constructed wetlands systems(CWs), two horizontal subsurface flow(HSSF) CWs and two vertical subsurface flow(VSSF) CWs, using sand as substrate and Typha latifolia as wetland plants, were constructed and put into use for synthetic wastewater treatment. Five months later, significant spatial variations of TP and inorga...

Phosphorus is a limiting nutrient in freshwater ecosystems. Therefore, it of great significance to use remote sensing technology estimate the Total phosphorus (TP) concentration lake body and identify contribution TP inflow load surrounding area body. In this study, two main frameworks (empirical method machine learning algorithm) for estimation are proposed applied development Nanyi Lake algor...

  This study examines the theoretical and empirical aspects of the effect of capital inflow on exchange rate in 14 developing countries for the period 1980-2009. We developed an empirical model to investigate the effects of term of trade, real per capita output and trade openness on real exchange rate using d ynamic and heterogeneous panel and Pool Mean Group (PMG) methods. Estimation results s...
