Methyl methacrylate (MMA) was successfully grafted onto cellulose nanofibers (CNFs) at room temperature in an emulsion system using a diethyl(1,10-phenanthroline N1,N10)zinc(II) complex (Phen-DEZ) with oxygen as the radical initiator. The effects of reaction temperature, initiator concentration, and monomer content on grafting were investigated. molecular weight non-grafted PMMA, which produced...

We study structural change in the historical consumption expenditure of United States, Kingdom, Canada, and Australia over more than a century. characterize most general class preferences time-additive setting that admits aggregation saving decision allows us to identify preference parameters from aggregate data. parameterize estimate such intertemporally aggregable (IA) discuss their propertie...

We examined the in vitro activity of 2-desamino-5,8-dideazafolate and 2-desamino-N10-propargyl-5,8-dideazafolate (desamino-CB3717), the more water-soluble 2-desamino analogues of 5,8-dideazafolate and N10-propargyl-5,8-dideazafolic acid (CB3717). We report Ki values for the inhibition of L1210 thymidylate synthase (TS) of 2 and 0.027 microM for 2-desamino-5,8-dideazafolate and desamino-CB3717, ...

Abstract. PMCAMx-UF, a three-dimensional chemical transport model focusing on the simulation of ultrafine particle size distribution and composition has been extended with addition reactions aging semivolatile anthropogenic organic vapors, emissions intermediate-volatility compounds (IVOCs), production extremely low-volatility (ELVOCs) by monoterpenes. The is applied in Europe to quantify effec...

BACKGROUND There are conflicting results on the relationship of N5,N10-methylenetetrahydrofolate reductase C677T gene variation in coronary artery disease and myocardial infarction. METHODS AND RESULTS We analysed this gene variation in 2453 male Caucasians whose coronary anatomy was defined by coronary angiography. In the total sample, the C677T gene polymorphism was not associated with the ...

The property that Rasch recognised can be understood by considering two persons A and B with imagined abilities βA and βB. If these two persons attempt a set of test items, and a tally is kept of the number of items N10 that person A answers correctly but B answers incorrectly, and of the number of items N01 that person B answers correctly but A answers incorrectly, then under the Rasch model, ...

This study determined whether "living high-training low" (LHTL)-simulated altitude exposure increased the hypoxic ventilatory response (HVR) in well-trained endurance athletes. Thirty-three cyclists/triathletes were divided into three groups: 20 consecutive nights of hypoxic exposure (LHTLc, n = 12), 20 nights of intermittent hypoxic exposure (four 5-night blocks of hypoxia, each interspersed w...
