Seismic Evaluation of Low-Rise Reinforced Masonry Buildings with Flexible Diaphragms
Authors: Cohen GL , Klingner RE , Hayes JR , Sweeney SC
Published: June 2006

This paper provides an integrated approach to the seismic evaluation of low-rise reinforced masonry buildings with flexible roof diaphragms. The paper is divided into four phases. In Phase 1 (Behavior), results from shaking-table testing, quasi-static testing, and analytical predictions are integrated to provide a coherent description of the seismic response of low-rise reinforced masonry buildings with flexible roof diaphragms. Two half-scale, low-rise reinforced masonry buildings with flexible roof diaphragms are subjected to earthquake ground motions on the Tri-axial Earthquake and Shock Simulator at the United States Army Construction Engineering Research Laboratory, Engineer Research and Development Center. Following the shaking-table tests, diaphragms and top four courses of attached masonry walls are salvaged from the half-scale structures and tested quasi-statically in their own plane. A new index, the diaphragm drift ratio, is introduced to describe the potential for diaphragm damage. In Phase 2 (Analysis), coordinated analytical modeling is developed and implemented to corroborate and extend the results of that experimental work, and to examine the efficacy and accuracy of different analytical modeling approaches. Linear elastic finite-element models, simplified two-degree-of-freedom models, and nonlinear lumped-parameter models are developed; all agree well with measured responses. In Phase 3 (Seismic Evaluation), the first two phases are used to develop and verify a simple extension to FEMA 310, the predominant seismic evaluation methodology for low-rise reinforced masonry building with flexible diaphragms. In Phase 4 (Application and Verification), the proposed extension, applied to four existing buildings, is shown to be simple, useful, and necessary.
"The Queen's Twin": Sarah Orne Jewett and Lesbian Symmetry
Authors: SOLOMON MELISSA
Published: June 2006

Do some ideas "survive all changes of time and national vicissitude"? The question belongs to Sarah Orne Jewett (1849-1909), the South Berwick, Maine author whose fictions are spun from communities of widowed women living along the Maine seacoast after the death of the shipping industry in Maine. A regional author ever mindful of differences between individuals, regions, and nations, whose fictional sea-captains know "a hundred ports . . . and could see outside the battle for town clerk here in Dunnet,"Jewett nevertheless invents female characters who share uncanny, sexualized, exactly symmetrical understandings between them. This essay explores the concept of symmetry and the corresponding affects living in and around those figurations of lesbian desire. "The Queen's Twin" is the title of Jewett's most unusual section in her masterpiece,The Country of the Pointed Firs, and the moniker refers to Mis' Abby Martin, a Maine woman who is convinced that she and Queen Victoria are twins, despite the ocean between them. Throughout the stages of her life, Abby has tracked the similarities between them, including a shared birth date, marriage to men named Albert, sons named Edward, widowhood, and countless other shared realities. Abby's passionate interest in Victoria builds as much on the coincidence of their mutual birth and imagined twinship as on the differences in their stations. Abby's cognizance of their differences occasions the richness of these affective moments.
The Role of the Bovine Growth Hormone Receptor and Prolactin Receptor Genes in Milk, Fat and Protein Production in Finnish Ayrshire Dairy Cattle

Published: June 2006

We herein report new evidence that the QTL effect on chromosome 20 in Finnish Ayrshire can be explained by variation in two distinct genes, growth hormone receptor (GHR) and prolactin receptor (PRLR). In a previous study in Holstein–Friesian dairy cattle an F279Y polymorphism in the transmembrane domain of GHR was found to be associated with an effect on milk yield and composition. The result of our multimarker regression analysis suggests that in Finnish Ayrshire two QTL segregate on the chromosomal region including GHR and PRLR. By sequencing the coding sequences of GHR and PRLR and the sequence of three GHR promoters from the pooled samples of individuals of known QTL genotype, we identified two substitutions that were associated with milk production traits: the previously reported F-to-Y substitution in the transmembrane domain of GHR and an S-to-N substitution in the signal peptide of PRLR. The results provide strong evidence that the effect of PRLR S18N polymorphism is distinct from the GHR F279Y effect. In particular, the GHR F279Y has the highest influence on protein percentage and fat percentage while PRLR S18N markedly influences protein and fat yield. Furthermore, an interaction between the two loci is suggested.
Mapping Quantitative Trait Loci for Longitudinal Traits in Line Crosses
Authors: Yang Runqing , Tian Quan , Xu Shizhong
Published: June 2006

Quantitative traits whose phenotypic values change over time are called longitudinal traits. Genetic analyses of longitudinal traits can be conducted using any of the following approaches: (1) treating the phenotypic values at different time points as repeated measurements of the same trait and analyzing the trait under the repeated measurements framework, (2) treating the phenotypes measured from different time points as different traits and analyzing the traits jointly on the basis of the theory of multivariate analysis, and (3) fitting a growth curve to the phenotypic values across time points and analyzing the fitted parameters of the growth trajectory under the theory of multivariate analysis. The third approach has been used in QTL mapping for longitudinal traits by fitting the data to a logistic growth trajectory. This approach applies only to the particular S-shaped growth process. In practice, a longitudinal trait may show a trajectory of any shape. We demonstrate that one can describe a longitudinal trait with orthogonal polynomials, which are sufficiently general for fitting any shaped curve. We develop a mixed-model methodology for QTL mapping of longitudinal traits and a maximum-likelihood method for parameter estimation and statistical tests. The expectation-maximization (EM) algorithm is applied to search for the maximum-likelihood estimates of parameters. The method is verified with simulated data and demonstrated with experimental data from a pseudobackcross family of Populus (poplar) trees.
An Empirical Bayes Method for Updating Inferences in Analysis of Quantitative Trait Loci Using Information From Related Genome Scans
Authors: Zhang Kui , Wiener Howard , Beasley Mark , George Varghese , Amos Christopher I , Allison David B
Published: June 2006

Individual genome scans for quantitative trait loci (QTL) mapping often suffer from low statistical power and imprecise estimates of QTL location and effect. This lack of precision yields large confidence intervals for QTL location, which are problematic for subsequent fine mapping and positional cloning. In prioritizing areas for follow-up after an initial genome scan and in evaluating the credibility of apparent linkage signals, investigators typically examine the results of other genome scans of the same phenotype and informally update their beliefs about which linkage signals in their scan most merit confidence and follow-up via a subjective–intuitive integration approach. A method that acknowledges the wisdom of this general paradigm but formally borrows information from other scans to increase confidence in objectivity would be a benefit. We developed an empirical Bayes analytic method to integrate information from multiple genome scans. The linkage statistic obtained from a single genome scan study is updated by incorporating statistics from other genome scans as prior information. This technique does not require that all studies have an identical marker map or a common estimated QTL effect. The updated linkage statistic can then be used for the estimation of QTL location and effect. We evaluate the performance of our method by using extensive simulations based on actual marker spacing and allele frequencies from available data. Results indicate that the empirical Bayes method can account for between-study heterogeneity, estimate the QTL location and effect more precisely, and provide narrower confidence intervals than results from any single individual study. We also compared the empirical Bayes method with a method originally developed for meta-analysis (a closely related but distinct purpose). In the face of marked heterogeneity among studies, the empirical Bayes method outperforms the comparator.
Deformation and fracture behavior of tungsten fiber-reinforced bulk metallic glass composite subjected to transverse loading

Published: June 2006

Deformation and fracture behavior of Zr41.25Ti13.75Ni10Cu12.5Be22.5 bulk metallic glass and its composite containing transverse tungsten fibers in compression were investigated. The monolithic metallic glass and the tungsten fiber composite specimens with aspect ratios of 2 and 1 are shown to have essentially the same ultimate strength under compression. The damage processes in the bulk metallic glass composite consisted of fiber cracking, followed by initiation of shear band in the glassy matrix mainly from the impingement of the fiber crack on the fiber/matrix interface. The site of the shear band initiation in the matrix is consistent with the prediction of finite element modeling. Evidence is present that the tungsten fiber can resist the propagation of the shear band in the glassy matrix. However, the compressive strain to failure substantially decreased in the present composite compared with the composites containing longitudinal tungsten fibers. Finally, the two composite specimens fractured in a shear mode and almost all the tungsten fibers contained cracks.
Atomic-level simulation of epitaxial recrystallization and phase transformation in SiC
Authors: Gao F. , Devanathan R. , Zhang Y. , Posselt M. , Weber W.J.
Published: June 2006

A nano-sized amorphous layer embedded in an atomic simulation cell was used to study the amorphous-to-crystalline (a-c) transition and subsequent phase transformation by molecular-dynamics computer simulations in 3C–SiC. The recovery of bond defects at the interfaces is an important process driving the initial epitaxial recrystallization of the amorphous layer, which is hindered by the nucleation of a polycrystalline 2H–SiC phase. The kink sites and triple junctions formed at the interfaces between 2H– and 3C–SiC provide low-energy paths for 2H–SiC atoms to transform to 3C–SiC atoms. The spectrum of activation energies associated with these processes ranges from below 0.8 eV to about 1.9 eV.
Inorganic pigments based on fluorite-type oxynitrides
Authors: Pérez-Estébanez M. , Pastrana-Fábregas R. , Isasi-Marín J. , Sáez-Puche R.
Published: June 2006

Zirconia oxynitride rare-earth-doped pigments were prepared by ammonolysis of the zirconium rare-earth oxides, previously synthesized using the citrate complexation/calcination route. Different coloration has been obtained, the intensity of which is a function of the nitrogen amount in the case of the oxynitrides; in the case of the oxides, both color and intensity depend on the doping amount of rare earth. The obtained phases, Zr(1−x)CexO2, Zr(1−x)RxO(2−x/2)□x/2, with R = Eu or Er and Zr(1−x)RxO(2−x/2−3/2y)Ny□x/2■y/2 (R = Ce, Eu, and Er), have been characterized by x-ray powder diffraction, scanning electron microscopy, and reflectance spectra data. These results show that the phases with minor rare-earth concentration adopt a baddeleyite-type structure, with a monoclinic symmetry, space group P21/c. By increasing the rare-earth doping, the obtained phases crystallize with the fluorite structure with tetragonal (P42/nmc) or cubic symmetry (Fm¯3m). On the other hand, the study of the magnetic properties of the oxides and oxynitrides indicate a paramagnetic behavior, and in the case of the cerium oxide, the nitridation process produces the reduction from Ce4+ to Ce3+. Diffuse reflectance data and CIE-LAB color coordinates suggest that these ceramics based on nitrogen containing zirconia are expected to be promising candidates as new ecological inorganic pigments.
Key role of milling in the optimization of TiO2 nanoinks
Authors: Sanson A. , Gardini D. , Montanari G. , Galassi C. , Roncari E.
Published: June 2006

Nanostructured films of TiO2 are becoming more and more attractive as a consequence of their improved sensing properties. Screen printing represents an important low-cost alternative for the production of high-performance devices for the automotive industry. However, to obtain films with superior properties, the composition and each step of the ink production must be carefully controlled. Milling strongly influences the rheological properties of the ink and, as a consequence, the quality of the deposited film. The as-prepared ink was homogenized in a four steps-process with a three-roll mill, and the rheological properties at each intermediate stage were measured. The results showed the dramatic effect of the milling on the flow properties of the nanoink and suggested the importance of a careful control of this step. The rheological behavior of the inks was explained using the basic idea of the transient network theory (TNT) for physically cross-linked networks of polymer solutions. Only an optimized cycle of milling can assure the necessary reproducibility of the ink properties as well as their time stability.
Piezoelectric and dielectric tunabilities of ultra-thin ferroelectric heterostructures
Authors: Zhong S. , Alpay S.P. , Nagarajan V.
Published: June 2006

The scaling of the piezoelectric and dielectric constants with film thickness in ultra-thin ferroelectric heterostructures is investigated. Epitaxial (001) PbZr0.2Ti0.8O3 films ranging in thickness from 5 nm to 30 nm with top and bottom SrRuO3 electrodes were grown onto (001) SrTiO3 substrates via pulsed laser deposition. Piezoelectric and dielectric measurements were performed using an atomic force microscope. The remnant value of the out of plane piezoresponse (d33) decreases from 60 pm/V for the 30 nm film to just 7 pm/V for the 5 nm film. This systematic decline in d33 is accompanied by a corresponding increase in the coercive field. The d33 loops show a systematic increase in tilt towards the applied field axis as function of reducing thickness coupled with a decrease in piezoelectric tunability. The small-signal relative dielectric response in the direction normal to the film-substrate interface decreases from 140 for a 50 nm film to just 60 for a 8 nm film. A similar drop is also observed in the dielectric tunability, from ∼17% to approximately −2% at an electric field of 750 kV/cm with the film thickness decreasing from 50 nm to 8 nm. We show that these observations cannot be explained using a straightforward application of a modified Landau-Devonshire thermodynamic model that incorporates the internal stresses due to the lattice and thermal expansion mismatch between the film and the substrate. We attribute this behavior to degradation in the polarization due to an intrinsic finite size effect.
The mechanical properties of freestanding electroplated Cu thin films
Authors: Xiang Y. , Tsui T.Y. , Vlassak J.J.
Published: June 2006

The plane-strain bulge test is used to investigate the mechanical behavior of freestanding electroplated Cu thin films as a function of film thickness and microstructure. The stiffness of the films increases slightly with decreasing film thickness because of changes in the crystallographic texture and the elastic anisotropy of Cu. Experimental stiffness values agree well with values derived from single-crystal elastic constants and the appropriate orientation distribution functions. No modulus deficit is observed. The yield stress of the films varies with film thickness and heat treatment as a result of changes in the grain size of the films. The yield stress follows typical Hall-Petch behavior if twins are counted as distinct grains, indicating that twin boundaries are effective barriers to dislocation motion. The Hall-Petch coefficient is in good agreement with values reported for bulk Cu. Film thickness and crystallographic texture have a negligible effect on the yield stress of the films.
Effect of passivation on stress relaxation in electroplated copper films
Authors: Gan Dongwen , Ho Paul S. , Pang Yaoyu , Huang Rui , Leu Jihperng , Maiz Jose , Scherban Tracey
Published: June 2006

The present study investigated the effect of passivation on the kinetics of interfacial mass transport by measuring stress relaxation in electroplated Cu films with four different cap layers: SiN, SiC, SiCN, and a Co metal cap. Stress curves measured under thermal cycling showed different behaviors for the unpassivated and passivated Cu films, but were essentially indifferent for the films passivated with different cap layers. On the other hand, stress relaxation measured under an isothermal condition revealed clearly the effect of passivation, indicating that interface diffusion controls the kinetics of stress relaxation. The relaxation rates in the passivated Cu films were found to decrease in the order of SiC, SiCN, SiN, and metal caps. This correlates well with previous studies on the relationship between interfacial adhesion and electromigration. A kinetic model based on coupling of interface and grain-boundary diffusion was used to deduce the interface diffusivities and the corresponding activation energies.
Sustainable water—lessons from the developing world
Authors: Wong K. -F. S.
Published: June 2006

By comparing and contrasting the underlying principles of sustainable water management (SWM) in England and developing countries, this paper highlights the features and limitations of current water practices in achieving long-term sustainability in England. The over-reliance on formal and judiciary institutions fails to acknowledge the complex roles of agency and socially embedded institutions in shaping water-using norms and behaviour. The minimal level of community participation does not help in building trust among water users, regulators and suppliers. Decentralisation, in the form of privatisation, does not necessarily enhance water efficiency, and the universal application of water regulations may not fit into local conditions.
Accommodating the Strangeren Casa:How Mexican American Elders and Caregivers Decide to Use Formal Care
Authors: Crist Janice D. , García-Smith Dianna , Phillips Linda
Published: June 2006

Mexican American elders have higher levels of functional impairment and chronic illness, yet they use formal home care services less than do non-Hispanic White elders. This article describes the processes by which Mexican American elders and their caregivers decide to use home care services. Interviews were conducted with Mexican American elders (n= 11) and family caregivers (n= 12) for a sample of 23 individuals. The emerging substantive grounded theory included three stages that described the process of deciding to use home care services:Taking Care of our Own, Acknowledging Options,andBecoming Empowered.The processes describe how Mexican American families eventually accept home care services while maintaining their cultural norm of taking care of elders. The theory gives voice to both elders and caregivers in this process, adds to extant knowledge, and shapes interventions to support traditional Mexican American family values such as elders’ staying at home as long as possible. The theory meets nursing’s goals of reducing health care disparities by improving or sustaining elders’ health and functional ability, decreasing the caregiving burden, and reducing health care costs.

The present study was aimed at the preparation and performance evaluation of Intacglobin®‐loaded liposomes for selective drug presentation to the lungs. Egg phosphatidylcholine‐ and cholesterol‐based liposomes (1:1 and 1:0.25 mol/mol) were prepared by a dehydration–rehydration procedure. A tissue distribution study after single intranasal administration of 0.5 µCi 125I‐Intacglobin®‐loaded liposomes was conducted in Balb/c mice. The efficiencies of drug entrapment (30%) and the average diameters did not differ significantly between the two liposome formulations. However, liposomes composed of an increased cholesterol amount showed a lower in vitro drug release rate. The airway penetration efficiency of the liposomal formulation was determined by the cumulative percentage of the dose reaching the lungs (AUC) and its sojourn time therein, and were 1.7‐ and 2.2‐times higher compared with the plain 125I‐ Intacglobin® solution‐based formulation, respectively. A significantly greater (p<0.001) drug localization index after 24 h was found at the lungs in comparison with the other tissues (p<0.01), although similar values were detected between groups following administration of either liposomes or control solutions, despite the formulations attributes. In conclusion, it is suggested that longer Intacglobin exposure at the pulmonary region is observed after administration of the liposomal formulation. The results open future perspectives in assessing local passive immunization for the treatment of respiratory infectious diseases. Copyright © 2006 John Wiley & Sons, Ltd.
