Creep deformation and rupture experiments are conducted on samples of the Ni-base superalloy directionally solidified GTD-111 tested at temperatures between 649°C and 982°C and two orientations (longitudinally and transversely oriented). The secondary creep constants are analytically determined from creep deformation experiments. The classical Kachanov–Rabotnov model for tertiary creep damage i...

BACKGROUND The aim of the study was to record the incidence of treatment for infertility prior to development of gestational trophoblastic disease (GTD). METHODS AND RESULTS A retrospective analysis was undertaken of 231 consecutive women receiving chemotherapy for persistent GTD at Weston Park Hospital, Sheffield, from 1991 to 2001. Three patients in this group had received treatment for inf...

Allen (2001) proposed the “Getting Things Done” (GTD) method for personal productivity enhancement, and reduction of the stress caused by information overload. This paper argues that recent insights in psychology and cognitive science support and extend GTD’s recommendations. We first summarize GTD with the help of a flowchart. We then review the theories of situated, embodied and distributed c...

We start by studying the Goldberger-Treiman discrepancy (GTd) ∆ = (2.259± 0.591)%. Then we look at the πN σ term, with the dimensionless ratio σN/2mN = 3.35%. Finally we return to predicting (via the quark model) the πN coupling constant, with GTd ∆ → 0 as mq → mN/3. Given the recent new value of the πNN coupling constant [1] g πNN/4π = 13.80± 0.12 or gπNN = 13.169± 0.057, (1) along with the ob...

Background Gestational trophoblastic disease (GTD) defines a heterogenenous group of interrelated lesions that arise from the trophoblastic epithelium of the placenta. There are several histologically distinct types of GTD: hydatiform mole (complete or partial), persistant/invasive gestational trophoblastic neoplasia (GTN), choriocarcinoma and placenta site trophoblastic tumors. The aim of this...

We study the performance of compressed beamforming weights feedback technique in generalized triangular decomposition (GTD) based MIMO system. GTD is a beamforming technique that enjoys QoS flexibility. The technique, however, will perform at its optimum only when the full knowledge of channel state information (CSI) is available at the transmitter. This would be impossible in the real system, ...

Myosin Va is a well known processive motor involved in transport of organelles. A tail-inhibition model is generally accepted for the regulation of myosin Va: inhibited myosin Va is in a folded conformation such that the tail domain interacts with and inhibits myosin Va motor activity. Recent studies indicate that it is the C-terminal globular tail domain (GTD) that directly inhibits the motor ...
