Accurate predicting the interface gap (pad wear) is critical for controlling both mechanical and chemical removal rate and within wafer non-uniformity (WIWNU). These results show that fluid is an important factor which needs to be included into the model in predicting the interface gap and surface profile evolution of the pad during polishing and conditioning.

“The twin structure, habit plane orientation, and morphology of B19 martensite in TiAu, which is a candidate shape memory alloy (SMA) for high-temperature

and biomedical applications, were investigated by conventional transmission electron microscopy. Almost all internal twins were 111 type I twins as lattice-invariant deformation (LID). The < 211 > type II twin was scarcely observed in TiAu, unlike in TiPd Pfizer Licensed Compound Library high throughput and TiPt SMAs. The habit plane roughly corresponded to the twinning plane (K-1 plane) of the < 211 > type II twin because of the superb lattice parameter ratio of TiAu. As a result, an energy-minimizing microstructure referred to Selleckchem VX 770 as “twins within twins” appears as the major microstructure. The selection rules for the twinning of LID are also discussed

considering the results of extensive studies on LID in SMAs.”
“Anterior cruciate ligament injury affects roughly 120 000 athletes in the United States every year. One of the most common techniques is the use of a bone-patellar tendon-bone graft. Graft harvest creates a sizeable defect in the remaining patellar tendon. Closure of this defect is based on surgeon preference. To date there has been no study on the effects of defect closure on the mechanical properties of remaining donor patellar tendon. The goal of this study was to investigate AZD5582 supplier the effect of closure on both the strength and stiffness of the remaining patellar tendon. 7 pairs of fresh frozen cadaver patellar tendons were matched by tendon

dimensions. Bone-patellar tendon-bone grafts were harvested from all of the specimens and then half of the paired tendons underwent defect closure. All of the donor tendons were then tested in a servohydraulic load frame to failure at a constant displacement rate at room temperature. This study found no differences in the load at failure, the engineering failure stress, stiffness or in the engineering modulus between the donor tendons that underwent defect closure versus those that did not.”
“Health Science students at the University of KwaZulu-Natal perform better in their professional modules compared with their physiology modules. The pass rates of physiology service modules have steadily declined over the years. While a system is in place to identify “at-risk” students, it is only activated after the first semester.
