Directionally-solidified (DS) GTD-111 is a Ni-base superalloy designed to withstand damage occurring in the first and second stage blades of gas-powered turbines. Because of the distinctive microstructure of this material, the manner in which fatiguecreep-environment damage mechanisms interact to initiate cracks is sensitive to grain structure and chemical composition. Along with fatigue cyclin...

Transformations are a common technique used to linearize data so that simple linear regression can be applied. A common transformation used is the logarithmic transformation. This transforms data that follows an exponential pattern so that a straight line can be fit to it. In this study human chorionic gonadotropin (hCG) levels in women with gestational trophoblastic disease (GTD), which are kn...

We investigated the stability of certain erythrocytic enzymes as assayed qualitatively by fluorescence spot tests. Preservation of the activities of glucose6-phosphate dehydrogenase (GPD), pyruvate kinase (PK), triose phosphate isomerase (TPI), glutathione reductase (GTD), and NADH diaphorase (ND) in heparin, glucose-EDTA, or Alsever’s solution was studied at -20#{176}C and 30#{176}C. In Alseve...

Abstract Objective To provide guidelines for surgery and reduce the incidence of fracture, this study analyzed relationship between femoral fracture related factors in direct anterior approach (DAA) total hip arthroplasty (THA) lateral decubitus position. Method A retrospective series 273 consecutive patients who underwent THA with DAA position was analyzed. Each performed by same surgeon a con...

Gestational trophoblastic disease is a spectrum of placental disorders ranging from benign molar pregnancies to the neoplastic conditions such as invasive mole and choriocarcinoma. These patients are identified early due to markedly elevated hCG levels and characteristic ultrasound findings. Uterine evacuation is the recommended treatment, while chemotherapy can be reserved for patients with re...

Temporal difference learning is one of the oldest and most used techniques in reinforcement learning to estimate value functions. Many modifications and extension of the classical TD methods have been proposed. Recent examples are TDC and GTD(2) ([Sutton et al., 2009b]), the first approaches that are as fast as classical TD and have proven convergence for linear function approximation in onand ...

Gestational trophoblastic disease (GTD) is a condition that develops from abnormal proliferation of placental trophoblasts. A rare division GTD partial mole with co-existing live fetus-a also referred to as “sad fetus syndrome” We report case 24-year-old, primigravida 26 weeks gestational age single intrauterine gestation coexisting molar pregnancy who had spontaneous preterm delivery at 27 wee...
