High nitrogen doped 300 mm silicon wafers annealed in 100 % argon ambient were investigated whether modified pulling conditions will lead to improved slip behavior and homogeneous radial oxygen precipitation. It turned out that increasing of the cooling rate during crystal pulling is beneficial on these wafer defect parameters. The void morphology was investigated by TEM and oxygen precipitatio...

In the Tropics more small drops and less large drops were found in oceanic precipitation than in continental precipitation at the given reflectivity. Similarly, more small drops and less large drops were found in remnants of a tropical cyclone than in frontal precipitation in mid-latitude site at the same reflectivity. The presence of small drops was higher in deep convective regime than in str...

BACKGROUND Rotavirus infection causes a significant proportion of diarrhea in infants and young children worldwide leading to dehydration, hospitalization, and in some cases death. Rotavirus infection represents a significant burden of disease in developing countries, such as those in South Asia. METHODS We conducted a meta-analysis to examine how patterns of rotavirus infection relate to tem...

[1] Cloudsat cloud radar data are used to investigate the vertical structure of cloud systems of the ITCZ across the West and East Pacific and its contribution to precipitation. Cloud radar data are collocated with precipitation rates from the Advanced Microwave Scanning Radiometer (AMSR) to examine differences in cloud top PDFs for different rain rate regimes. Heavily precipitating clouds have...

A facile co-precipitation method for the synthesis of well-dispersed NdFeO3 nanocrystals is developed in the presence of octanoic acid as surfactant. Co-precipitation can produce fine, high-purity, stoichiometric particles of single and multicomponent metal oxides. The product is characterized by Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), scanning electron microsc...

Unprecedented increases in air temperature and erratic precipitation patterns are predicted throughout the twenty-first century as a result of climate change. A recent global analysis of leatherback turtle hatchling output predicts that the nesting site at Sandy Point National Wildlife Refuge (SPNWR) will experience the most significant regional climate alterations. We aimed to identify how loc...

Plant invasions are an increasingly serious global concern, especially as the climate changes. Here, we explored how plant invasions differed between native- and novel exotic-dominated grasslands with experimental addition of summer precipitation in Texas in 2009. Exotic species greened up earlier than natives by an average of 18 days. This was associated with a lower invasion rate early in the...
