The piezoelectric voltage constant (g33) is a material parameter critical to voltage-type sensors for detecting vibrations or strains. Here, we report lead-free (K,Na)NbO3 (KNN)-based accelerometer with sensitivity enhanced by taking advantage of high g33. To achieve g33, the magnitudes charge d33 and dielectric permittivity εr KNN were best coupled manipulating intrinsic polymorphic phase boun...

The aim of this investigation was to evaluate the efficiency of partial treatment of animals infested with horn flies. Forty-five Guzerat cows between 4 and 7 years of age were divided into three groups (15 cows per group). The treatments were as follows: in groups G33 and G100, 33.3 and 100% of the cows were treated with one insecticide-impregnated ear tag/animal (40% diazinon), respectively, ...

A major barrier towards the study of the effects of drugs on Giant Cell Tumor of Bone (GCT) has been the lack of an animal model. In this study, we created an animal model in which GCT stromal cells survived and functioned as proliferating neoplastic cells. A proliferative cell line of GCT stromal cells was used to create a stable and luciferase-transduced cell line, Luc-G33. The cell line was ...

Due to the toxic of lead content ceramics, many free piezoelectric ceramics have received much attention. To obtain high properties for such poling conditions are often referred. In present work, effects electric field on Sm doped BCZT ceramic were investigated. The samples fabricated using a solid-state reaction technique. XRD analysis indicated that sample contained mixture phases rhombohedra...

A rapid surge in the research on piezoelectric sensors is occurring with the arrival of the Internet of Things. Single-phase oxide piezoelectric materials with giant piezoelectric voltage coefficient (g, induced voltage under applied stress) and high Curie temperature (Tc) are crucial towards providing desired performance for sensing, especially under harsh environmental conditions. Here, we re...

To assess the ca. 20-year polychlorinated biphenyl (PCB) contamination trends in Lake Hartwell, SC, sediment cores from the Twelve Mile Creek arm were collected in July 2004 at two sites (G30 and G33) first sampled in the mid-1980s. Congener-specific PCB data as a function of depth from the sediment-water interface for the 2004 sediment samples were compared to data obtained from 1987 and 1998 ...

Fourteen polymorphic microsatellites with perfect di-, tri-, and tetra-nucleotide repeats were identified for Panulirus homarus using Roche 454 whole-genome sequencing method. Microsatellites were efficiently co-amplified in four multiplexes and a singleplex, providing consistent and easily interpretable genotypes. The number of alleles per locus ranged from 2 to 11 with the observed and expect...

This research focuses on the synthesis and characterization of a piezoelectric (β-CN)APB/ODPA polyimide. The remanent polarization and piezoelectric d31 and g33 coefficients are reported to assess the effect of synthesis variations. Each of the materials exhibits a level of piezoelectricity which increases with temperature. The remanent polarization is retained at temperatures close to the glas...

I examine the role of debt-financed special payments to shareholders in defending incumbent managements during proxy contests. This role is based on shareholder preference for dividends and the consequent linkage between dividends and managerial security. The model is used to explain why the seemingly contradictory phenomena of (i) wealth losses to shareholders and (ii) lack of any substantial ...

In this paper, we examine how county unemployment rates affect consumers’ delinquency and bankruptcy behavior by focusing on the credit card market. In particular, after controlling for credit supply and shocks like divorce and health coverage we investigate whether consumer propensity for delinquency and bankruptcy changes with respect to the macroeconomic fluctuations across counties. Our res...
