L 左右 ,臭氧总投加量为 110 115 和 210mg/ L 条件下 ,30min BPA去除率可达 70 82 %和 90 %.通过考察不同臭氧投加量 不同本底条件 ,分析得出臭氧投加量对BPA 的降解占主导地位 UV254上有吸收的产物.通过考察臭氧氧化双酚 A过程中 UV254的变化 ,提出低臭氧投加量下BPA不能完全被氧化 ,而采用缩短臭氧投加时间 加大臭氧投加量以及提高水中余臭氧浓度等方法 ,有利于水中BPA的完全降解.

We tested the hypothesis that single nucleotide polymorphisms (SNPs) within genes of the NF-κB pathway are associated with altered clinical outcome of septic shock patients. We genotyped 59 SNPs in the NF-κB pathway in a discovery cohort of septic…

The problem of selecting parcels of land for inclusion within a protected reserve is formulated as a 0-1 programming model. The formulation addresses the objectives of minimizing cost and maximizing reserve area, while providing buffer zones around…

Long, continuous, marine sediment records from the subpolar North Atlantic document the glacial modulation of regional climate instability throughout the past 0.5 million years. Whenever ice sheet size surpasses a critical threshold indicated by the…

Thinking about Global Climate Change was once the domain of a small number of scientists and social thinkers but now is a vast industry of scientists, economists, politicians, and citizens of this planet. Where once a close look at the role of the…

Numerical modeling of the orbital evolution of interplanetary dust particles revealed that, over the past 1.2 million years, the rate of accretion of dust by Earth has varied by a factor of 2 to 3. These variations display a 100,000-year periodicity…

A new diatom record from Lake Victorias Pilkington Bay, subsampled at 21- to 25-year intervals and supported by 20 AMS dates, reveals a 10,000 calendar year environmental history that is supported by published diatom and pollen data from two nearby…

Local fire history covering the entire Holocene period at a dry forest site in North Karelia, eastern Finland (ca. 63degrees07'N, 30degrees44'E), was reconstructed on the basis of visible charcoal layers from peat deposits of a small mire basin.…

Dune fields and loess deposits of the Great Plains of North America contain stratigraphic records of eolian activity that can be used to extend the short observational record of drought. We present a 10,000 yr reconstruction of dune activity and…

An integrated barley transcript map (consensus map) comprising 1,032 expressed sequence tag (EST)-based markers (total 1,055 loci: 607 RFLP, 190 SSR, and 258 SNP), and 200 anchor markers from previously published data, has been generated by mapping…

We present measurements of the stable carbon isotope ratio in air extracted from Antarctic ice core and firn samples. The same samples were previously used by Etheridge and co-workers to construct a high precision 1000-year record of atmospheric CO2…

LIn China, the abundance of historical documentary records in the form of Fang Zhi (semiofficial local gazettes) offers an extraordinary opportunity for providing a high-resolution historical dataset for the frequency of typhoon strikes. We have…

To multidecadal modes in ocean/atmosphere dynamics in the North Atlantic region have been identified using sea salt aerosol proxy records from northern Greenland ice cores over the last 1,000 years. Sea salt concentrations show a consistent…
-
High-resolution charcoal analysis of lake sediments and stand-age information were used to reconstruct a 1000-year fire history around Dog Lake, which is located in the montane spruce zone of southeastern British Columbia. Macroscopic charcoal 125…
