The element mercury (Hg) can develop large mass-independent fractionation (MIF) (Δ199Hg) due to photo-chemical reactions at Earth's surface. This results in globally negative Δ199Hg for terrestrial sub-aerially-derived materials and positive sub-aqueously-derived marine sediments. mantle composition least affected by crustal recycling is estimated from high-3He/4He lavas Samoa Iceland, providin...
The westerlies play an important role in driving climate change the Tibetan Plateau (TP). However, little is known about history of TP owing to limited observations and a lack robust reconstructions. widely distributed eolian loess eastern one ideal materials retrieve intensity for westerlies. A detailed grain-size endmember model analysis (EMMA) on Ganzi sequence located revealed that EMMA dec...
Privacy preservation (PP) has become an important issue in the information age to prevent expositions and abuses of personal information. This has attracted much research and k-anonymity is a well-known and promising model invented for PP. Based on the k-anonymity model, this paper introduces a novel and efficient member migration algorithm, called eM, to ensure kanonymity and avoid information...
BACKGROUND Alveolar echinococcosis (AE) is caused by the metacestode stage of Echinococcus multilocularis. Differential diagnosis with cystic echinococcosis (CE) caused by E. granulosus and AE is challenging. We aimed at improving diagnosis of AE on paraffin sections of infected human tissue by immunohistochemical testing of a specific antibody. METHODOLOGY/PRINCIPAL FINDINGS We have analysed...
The etch rates of GaAs and Al,Ga] _xAs (x = 0.09-1) in C2H6/H2 were investigated as a function oftime 0-12 min), gas flow rate (5-25 seem), total pressure (4-30 mTorr), plasma power density (0.56-1.32 W em2 ), and percentage ofC2H 6 in the discharge (1O%-50%). The etch rates are constant with time, and decrease with increasing Al content in the AIGaAs. The maximum etch rates occur at 25% by vol...
The magmatic activity (0-16 Ma) in Iceland is linked to a deep mantle plume that has been active for the past 62 My. Icelandic and northeast Atlantic basalts contain variable proportions of two enriched components, interpreted as recycled oceanic crust supplied by the plume, and subcontinental lithospheric mantle derived from the nearby continental margins. A restricted area in southeast Icelan...
BACKGROUND/OBJECTIVE The aim of this study was to examine the effect of high dietary methionine (Met) consumption on plasma and hepatic oxidative stress and dyslipidemia in chronic ethanol fed rats. MATERIALS/METHODS Male Wistar rats were fed control or ethanol-containing liquid diets supplemented without (E group) or with DL-Met at 0.6% (EM1 group) or 0.8% (EM2 group) for five weeks. Plasma ...
