Econometric evidence of cross‐market effects of generic dairy advertising
Authors: Cakir Metin , Balagtas Joseph V. 
Published: January 2010

AbstractWe estimate a dairy demand system to evaluate generic dairy advertising in the US, 1990–2005. Previous empirical studies of generic dairy advertising focus only on the market of the advertised good, ignoring potential spill‐over and feedback effects. We specify an LA/AIDS model of dairy demand, which allows consistent estimation of cross‐price and cross‐advertising effects across dairy product markets, and is flexible and satisfies the axioms of consumer theory. We use the non‐linear 3SLS estimator to address endogenous prices and serial correlation, and conduct bootstrapping to generate empirical distributions of elasticity estimates. Results suggest that cross‐market effects are economically and statistically important. Thus, econometric dairy demand models that ignore cross‐advertising and cross‐price effects are mis‐specified. Previous work that ignores substitution between fluid milk and cheese overstates producers' returns to generic advertising for either product. © 2010 Wiley Periodicals, Inc.
Trade implications of price discrimination in a domestic market
Authors: Kuga Nobunori , Suzuki Nobuhiro , Kaiser Harry M. 
Published: January 2010

AbstractThis study examines how domestic price discrimination between fluid and manufacturing milk influences dairy trade. Two types of dairy models are used for the study. The first one is a stylized mathematical model which is used to explore the relative trade effects of domestic price discrimination accompanied with revenue pooling mechanism versus border measures in dairy product markets. The second one is a partial equilibrium, multiple‐region model of dairy policy and trade, which is used to see the empirical implication of domestic price discrimination for six major dairy producers.The analytical results identify the trading status as the key to determine the relative trade effects. While domestic price discrimination is always less trade distorting than border measures in a net‐importer case, the relative trade distortiveness depends on the export volume in a net exporter case. The theoretical possibility that domestic price discrimination is more trade distorting than border measures is found when the ratio of dairy export to domestic manufacturing milk consumption is very high. The results also indicate that while the both support measures increase dairy export, domestic price discrimination may place greater economic burden on fluid milk consumers and less economic burden on tax payers than border measures. In addition, the results imply that domestic price discrimination schemes can be effective trade protective measures for Canada, Japan and the United States, where the schemes are currently being implemented. © 2010 Wiley Periodicals, Inc.
Electroanalytical studies on electrically conducting polyaniline:polyethyleneterephthalate composite films
Authors: Khalid Mohd , Mohammad Faiz 
Published: January 2010

AbstractPolyaniline (PANI):polyethyleneterephthalate (PET) composite was prepared by chemical polymerization of aniline diffused in the PET matrix. Thus prepared composite films were characterized by fourier‐transform infrared spectroscopy and scanning electron microscopy and their electrical properties and the thermo‐oxidative stability was studied by thermogravimetry and differential thermal analysis. The stability in terms of DC electrical conductivity retention was studied in an oxidative environment by two slightly different techniques viz. isothermal and cyclic techniques. DC electrical conductivity of composite films was found to be stable up to 90°C for most of the composites under ambient conditions. The composite films were employed as cathode material in secondary cells containing 1M ZnCl2 solution. The studies were carried out on the charge/discharge cycles under a constant current load 140 mA. The composite films showed similar behavior in electrolyte solution and cell response is reversible. To determine the diffusion coefficient for the chloride ions diffusion into the composite films electrochemically, galvanostatic pulse method was used. The diffusion coefficient was estimated to be ∼ 3.28 × 10−12 cm2 s−1. © 2010 Wiley Periodicals, Inc. J Appl Polym Sci, 2010
Crystallization kinetics of cis‐1,4‐polybutadiene
Authors: Di Lorenzo Maria Laura 
Published: January 2010

AbstractThe isothermal and nonisothermal crystallization kinetics of cis‐1,4‐polybutadiene has been investigated with respect to the content of cis units and the linearity of the main chain. The rate of spherulite growth increases with chain regularity as the presence of branches as well as segments with different configurations slows the crystallization rate. The major parameter that determines the crystallization rate is the presence in the formulation of heterogeneities that favor the formation of primary nuclei and determine an anticipated onset of crystallization. As the activity of the heterogeneous nuclei depends more on the type and number of foreign particle than on any chain parameter, no straightforward information on the influence of the chain structure on the crystallization rate can be derived by mere calorimetric analysis, at least for analyzed samples. It is only with combined analysis by optical microscopy that comprehensive information on the crystallization kinetics of cis‐1,4‐polybutadiene can be derived. The results reported in this contribution point out the importance, in polymer science, of preferring complementary instrumentation and not limiting experimental investigations to a single technique of analysis. © 2010 Wiley Periodicals, Inc.

Synthesis and characterization of hetarylazo disperse colorants: Preparation and properties of conventional and microemulsified inks for polyester ink‐jet printing
Authors: Kosolia C. T. , Tsatsaroni E. G. 
Published: January 2010

AbstractThe synthesis and characterization of three hetarylazo disperse colorants are described. These compounds were used for the preparation of conventional inks and/or oil‐in‐water microemulsions (microemulsified dyes). The viscosity, conductivity, surface tension, and pH of these inks were studied over a period of time and discussed with respect to their structure. The particle size and particle size distribution of a representative microemulsion were compared to those of a corresponding conventional ink. The measured properties were compared to the properties of commercially available inks. © 2010 Wiley Periodicals, Inc. J Appl Polym Sci, 2010
Rheological behaviors of PVA/H2O solutions of high‐polymer concentration
Authors: Gao Han‐Wen , Yang Rong‐Jie , He Ji‐Yu , Yang Lei 
Published: January 2010

AbstractThe dynamic viscoelastic properties of poly(vinyl alcohol) (PVA)/H2O solutions with concentrations of 10 to 25 wt % have been characterized by controlled‐stress rheometry at 30°C. Parameters relating to the linear and nonlinear viscoelasticities include complex viscosity (η*), storage modulus (G′), loss tangent (tan δ), relaxation time (λ), thixotropy, and creep. Change curves of η*, G′, tanδ, and λ with frequency (ω) have been obtained for the PVA/H2O solutions. Creep and recovery testing yielded compliance (J′) curves with loading and unloading. Shear stress versus rate profiles of the PVA solutions have been obtained through thixotropic measurements. The PVA concentration has been found to have a profound influence on the rheological properties of the aqueous solutions. Four aqueous solutions of 10, 15, 20, and 25 wt % PVA at 30°C exhibited shear‐thinning and showed different transition behaviors of η* and G′ with frequency, and different degrees of creep under constant stress to recovery with time. The 10 wt % PVA solution was viscous and displayed the lowest η* and G′; the 25 wt % PVA solution was viscoelastic and displayed the highest η* and G′; the 15 and 20 wt % PVA solutions showed η* and G′ values and creep to recovery behaviors intermediate between those of the 10 wt % and 25 wt % PVA solutions. The different rheological properties of these PVA/H2O solutions are considered to correlate with interchain hydrogen bonds and shear‐induced orientation in the solutions. Shearing is able to break the intrachain and interchain hydrogen bonds, and, at the same time, the orientation creates new interchain hydrogen bonding. The reorganization of hydrogen‐bonding mode contributes to the transitions of the macroscopic viscoelasticity with frequency. © 2010 Wiley Periodicals, Inc. J Appl Polym Sci, 2010
Adsorption of nile red by poly(N‐isopropylacrylamide) gels in binary water/tetrahydrofuran mixtures
Authors: Thivaios I. , Bokias G. 
Published: January 2010

AbstractThe adsorption of Nile Red by poly(N‐isopropylacrylamide) (PNIPAM) gels in binary water/tetrahydrofuran solutions was investigated using absorption spectrophotometry as a function of the volume fraction of THF, φ. Due to the cononsolvency abilities of such binary solvent mixtures, deswelling of the PNIPAM gels is observed in water‐rich mixtures, 0 ≤ φ ≤ 0.6, while the gels reswell for φ > 0.6. The position of the absorption band of Nile Red before and after equilibration with the PNIPAM gels indicates that the composition of the external solvent mixture is not practically influenced by the swelling process. On the other hand, it is found that the gels can effectively adsorb Nile Red in water‐rich mixtures (φ < 0.6), whereas no significant adsorption was observed in tetrahydrofuran‐rich mixtures. In fact, about 80% of the dye is adsorbed by the PNIPAM gels, at φ = 0.2. Under these conditions, the rather shrunk PNIPAM gel offers a more convenient less polar environment for Nile Red than the water‐rich bulk solvent. © 2010 Wiley Periodicals, Inc.

Published: January 2010

AbstractPrenatal environmental exposures are among the risk factors being explored for associations with autism. We applied a new procedure combining multiple scan cluster detection tests to identify geographically defined areas of increased autism incidence. This procedure can serve as a first hypothesis‐generating step aimed at localized environmental exposures, but would not be useful for assessing widely distributed exposures, such as household products, nor for exposures from nonpoint sources, such as traffic.Geocoded mothers' residences on 2,453,717 California birth records, 1996–2000, were analyzed including 9,900 autism cases recorded in the California Department of Developmental Services (DDS) database through February 2006 which were matched to their corresponding birth records. We analyzed each of the 21 DDS Regional Center (RC) catchment areas separately because of the wide variation in diagnostic practices. Ten clusters of increased autism risk were identified in eight RC regions, and one Potential Cluster in each of two other RC regions.After determination of clusters, multiple mixed Poisson regression models were fit to assess differences in known demographic autism risk factors between the births within and outside areas of elevated autism incidence, independent of case status.Adjusted for other covariates, the majority of areas of autism clustering were characterized by high parental education, e.g. relative risks >4 for college‐graduate vs. nonhigh‐school graduate parents. This geographic association possibly occurs because RCs do not actively conduct case finding and parents with lower education are, for various reasons, less likely to successfully seek services.
NMR structure of duplex DNA containing the α‐OH‐PdG·dA base pair: A mutagenic intermediate of acrolein

Published: January 2010

AbstractAcrolein, a cell metabolic product and main component of cigarette smoke, reacts with DNA generating α‐OH‐PdG lesions, which have the ability to pair with dATP during replication thereby causing G to T transversions. We describe the solution structure of an 11‐mer DNA duplex containing the mutagenic α‐OH‐PdG·dA base pair intermediate, as determined by solution nuclear magnetic resonance (NMR) spectroscopy and retrained molecular dynamics (MD) simulations. The NMR data support a mostly regular right‐handed helix that is only perturbed at its center by the presence of the lesion. Undamaged residues of the duplex are in anti orientation, forming standard Watson‐Crick base pairs alignments. Duplication of proton signals at and near the damaged base pair reveals the presence of two enantiomeric duplexes, thus establishing the exocyclic nature of the lesion. The α‐OH‐PdG adduct assumes a syn conformation pairing to its partner dA base that is protonated at pH 6.6. The three‐dimensional structure obtained by restrained molecular dynamics simulations show hydrogen bond interactions that stabilize α‐OH‐PdG in a syn conformation and across the lesion containing base pair. We discuss the implications of the structures for the mutagenic bypass of acrolein lesions. © 2010 Wiley Periodicals, Inc.

Synthesis of S‐Adenosyl‐L‐homocysteine Capture Compounds for Selective Photoinduced Isolation of Methyltransferases
Authors: Dalhoff Christian , Hüben Michael , Lenz Thomas , Poot Peter , Nordhoff Eckhard , Köster Hubert , Weinhold Elmar 
Published: January 2010

AbstractUnderstanding the interplay of different cellular proteins and their substrates is of major interest in the postgenomic era. For this purpose, selective isolation and identification of proteins from complex biological samples is necessary and targeted isolation of enzyme families is a challenging task. Over the last years, methods like activity‐based protein profiling (ABPP) and capture compound mass spectrometry (CCMS) have been developed to reduce the complexity of the proteome by means of protein function in contrast to standard approaches, which utilize differences in physical properties for protein separation. To isolate and identify the subproteome consisting of S‐adenosyl‐L‐methionine (SAM or AdoMet)‐dependent methyltransferases (methylome), we developed and synthesized trifunctional capture compounds containing the chemically stable cofactor product S‐adenosyl‐L‐homocysteine (SAH or AdoHcy) as selectivity function. SAH analogues with amino linkers at the N6 or C8 positions were synthesized and attached to scaffolds containing different photocrosslinking groups for covalent protein modification and biotin for affinity isolation. The utility of these SAH capture compounds for selective photoinduced protein isolation is demonstrated for various methyltransferases (MTases) acting on DNA, RNA and proteins as well as with Escherichia coli cell lysate. In addition, they can be used to determine dissociation constants for MTase–cofactor complexes.

Published: January 2010

AbstractA collection of 2‐aminoimidazole/triazole amides has been synthesized and screened for antibiofilm activity. This class of small molecules was found to modulate the biofilm activity of Pseudomonas aeruginosa, a multidrug‐resistant strain of Acinetobacter baumannii (MDRAB), a methicillin‐resistant Staphylococcus aureus strain (MRSA), Escherichia coli, Rhodospirillum salexigens, Staphylococcus epidermidis, Vibrio vulnificus, and vancomycin‐resistant Enterococcus faecium as well as the yeast Candida albicans and Cryptococcus neoformans. Furthermore, lead compounds were found to not lyse red blood cells at active concentrations.
Mutant Lipase‐Catalyzed Kinetic Resolution of Bulky Phenyl Alkyl sec‐Alcohols: A Thermodynamic Analysis of Enantioselectivity
Authors: Vallin Michaela , Syrén Per‐Olof , Hult Karl 
Published: January 2010

AbstractThe size of the stereoselectivity pocket of Candida antarctica lipase B limits the range of alcohols that can be resolved with this enzyme. These steric constrains have been changed by increasing the size of the pocket by the mutation W104A. The mutated enzyme has good activity and enantioselectivity toward bulky secondary alcohols, such as 1‐phenylalkanols, with alkyl chains up to eight carbon atoms. The S enantiomer was preferred in contrast to the wild‐type enzyme, which has R selectivity. The magnitude of the enantioselectivity changes in an interesting way with the chain length of the alkyl moiety. It is governed by interplay between entropic and enthalpic contributions and substrates with long alkyl chains are resolved best with E values higher than 100. The enantioselectivity increases with temperature for the small substrates, but decreases for the long ones.
