Microstructural developments during sintering in 2 and 3 mol% Y2O3-stabilized tetragonal zirconia polycrystals (2Y- and 3Y-TZPs) and 8 mol% Y2O3-stabilized cubic zirconia (8Y-CSZ) were systematically investigated in the sintering temperature range of 1100–1500 °C. Above 1200 °C, grain growth in 8Y-CSZ was much faster than that in 2Y- and 3Y-TZPs. In the grain-boundary faces in these specimens, amorphous layers did not exist; however, Y3+ ions segregated at the grain boundaries over a width of 10 nm. The amount of segregated Y3+ ions in 8Y-CSZ was significantly less than in 2Y- and 3Y-TZPs. This indicates that an increase in segregated Y3+ ions retards grain growth. Therefore, grain growth behavior during sintering can be reasonably explained by the solute-drag mechanism of Y3+ ions segregating along the grain boundary. The segregation of Y3+ ions, which directly affects grain growth, is closely related to the driving force for grain-boundary segregation-induced phase transformation (GBSIPT).

We asked the Democratic and Republican presidential candidates how they stand on issues affecting the justice system. What type of judges would they select? Do they support a moratorium on the death penalty? Are the immigration laws too harsh? Before you vote, check out how their campaigns answered these and other questions.

George R. Husband, accounting educator, was a leader in research, service; teaching. His former students; admirers endowed a chair, three scholarships; an annual lecture series in his memory nearly forty years after his death in 1958. This article highlights his lasting accomplishments by examining his research (e.g., as an opponent of the LIFO method of inventory valuation, an advocate of price-level accounting; major proponent of the proprietary theory of financial accounting,; as one of the most prolific authors in The Accounting Review), service (e.g., as Vice President; President of the American Accounting Association); teaching. We also discuss Husband’s research in the context of other notable contemporary scholars; those whose works are consistent with Husband’s thoughts. 2008 Accounting Foundation.

Since the 1940s, advocacy of the establishment of audit committees was undertaken by regulatory agencies, and subsequently by the accounting profession, and committees representing combinations of interest groups. Over time, this advocacy literature has reflected changing views about the key responsibilities of audit committees. (more…)

Geographical Information System (GIS) technology has been a popular tool for visualization of accident data and analysis of hot spots in highways. Many traffic agencies have been using GIS for accident analysis. Accident analysis studies aim at the identification of high rate accident locations and safety deficient areas on the highways.

BACKGROUND: Gender bias has been reported in the diagnosis and treatment of patients with a variety of illnesses. In the context of our 10-station fourth year Objective Structured Clinical Evaluation, we queried whether this could influence diagnosis in a geriatric case. Case writers hypothesized that, due to this bias, the female standardized patient may be diagnosed with depression more often than the male. (more…)

The present study was conducted on bats from different locations in Turkey.Of 33 bats, belonging to 10 species, 10 individuals (30.3%) of four species were infected withgamasine mites. Fifty-three mites belonging to 2 families (Spinturnicidae and Macronyssidae) werecollected. (more…)

Abstract This study was the first to analyze the polymorphic characteristics of a widerange of genetic markers in three Lithuanian horse breeds. Genetic variation at seven red bloodcell alloantigen (blood group) loci, 10 biochemical genetic loci and 16 microsatellites wasexaminated in 31 Zemaitukai, (more…)
