The mechanism of pile-soil reaction in frozen ground is not clear at present, but it obvious that the reduction dead weight will be beneficial to seismic resistance bridges. In view limited bridge engineering practice high risk permafrost regions, paper addressed structural performance superstructure and its effect on piles these special regions. Four superstructures with different weights were...

Risk Attitudes and Well-Being in Latin America A common premise in both the theoretical and policy literatures on development is that people remain poor because they are too impatient to save and too risk averse to take the sort of chances needed to accumulate wealth. The empirical literature, however, suggests that this assumption is far from proven. We report on field experiments designed to ...

INTRODUCTION Carotid artery stenosis is one of the leading causes of ischemic stroke. Carotid artery stenting has become well-established as an effective treatment option for carotid artery stenosis. For this study, we aimed to determine the efficacy and safety of carotid stenting in a population-based large cohort of patients by analyzing the Taiwan National Healthcare Insurance (NHI) database...

The goal of this study was to determine outcomes related to limb salvage vs. amputation for treating high-grade and localized osteosarcoma in patients with pathological fractures. Literature search was conducted using Medline, Embase and the Cochrane Database. Two reviewers independently assessed all eligible publications. The primary outcome measurement was pooled odds ratio (OR) and 95% confi...

BACKGROUND The risk of falls is the most commonly cited reason for not providing oral anticoagulation, although the risk of bleeding associated with falls on oral anticoagulants is still debated. We aimed to evaluate whether patients on oral anticoagulation with high falls risk have an increased risk of major bleeding. METHODS We prospectively studied consecutive adult medical patients who we...

The research study was designed to compare the safety and efficacy of the regimen of 5-flurouracil with cisplatin of investigational arm with the reference regimen of gemcitabine with cisplatin for the treatment of gallbladder cancer. A total of 60 patients were enrolled in the study. Out of 30 patients enrolled in arm-A (Gemcitabine with Cisplatin) and 30 patients enrolled in arm-B (5-Fluroura...

The effect of an addition of 0.37 Wt % Won the overall transformation rate of the austenitepearlite reaction in a eutectoid steel is examined. Pearlite growth rates and interlamerllar spacing are measured as a function of transformation temperatures. Tungesten raises the Ael temperature, for most transformation temperatures, decreases the overall reaction rate, the growth rate and the interlame...

Mortgages play a significant role in the US economy. Americans predominantly use fixed-rate mortgages (FRMs) to avoid interest rate risk, but related risk aversion cost has not been analyzed yet. This paper fills gap by investigating of choosing FRMs over adjustable-rate (ARMs). We find that ex post, FRM borrowers made 12% – 23% higher payments 0.66% 1.62% potential ARM payment shocks. Conseque...
