The subarctic North Pacific is one of three major high nitrate, low chlorophyll (HNLC) oceanic regions, along with the Southern Ocean and the eastern equatorial Pacific. In these regions, uptake of nitrogen by phytoplankton is widely thought to be regulated by the availability of dissolved iron. The supply of dissolved iron is twofold: via atmospheric deposition of dust and via upward transport...

The chemical species in gas phase and on the surface of aluminum precursor (boro-hydride trimethylamine (ABHTMA)) for aluminum deposition process with the vacuum level and the hot wall temperature were studied using two kinds of Fourier transform infrared (FT-IR) spectroscopes which was installed at the end of the chamber. The absorbance of Al-H, B-H, C-H and C-N stretching features of the chem...

This standard is applicable to pressure-relieving and vapor depressuring systems. Although intended for use primarily in oil refineries, it is also applicable to petrochemical facilities, gas plants, liquefied natural gas (LNG) facilities, and oil and gas production facilities. The information provided is designed to aid in the selection of the system that is most appropriate for the risks and ...

The challenge for exposure science and the focus of this workshop were to address the current absence of innovative tools and approaches for assessing human exposures to chemicals. Fundamental and relevant assessment of the potential human health risks from chemicals depends on quality information about exposure as well as the hazards. However, to date, generation of information about chemical ...
