The 12 percent five-year survival rate for patients with non-small-cell lung cancer (NSCLC) has not changed in several decades. However, four randomized trials have shown a modest increase in the mean survival time of patients with advanced NSCLC who received systemic chemotherapy vs best supportive care (BSC), and two others have demonstrated a statistically significant survival advantage (ave...
In January 2014, the Affordable Care Act extended access to health insurance coverage to an estimated 30 million previously uninsured people. This issue brief provides state-level estimates of the increased demand for physician and hospital services that is expected to result from expanded access and assesses the sufficiency of the existing supply of providers to accommodate the anticipated inc...
In a retrospective study of 15 patients who were treated with collapse therapy for pulmonary tuberculosis on an average 30 years previously, we found 16 instances of exudation in the residual pocket: four were sterile and without fistula, ten had bronchial fistulae, one had an esophageal fistula, and one was a tuberculous empyema without fistula. Among the 11 exudations with bronchial or esopha...
data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
Daniella Chusyd thought her graduate career was on a predictable course when she accepted place the PhD programme at University of Alabama Birmingham (UAB), USA. ‘I intended to study exercise and nutrition/body composition in people’, recalls. But 5 week internship Tanzania threw Chusyd's plans into confusion. ‘I've always been animals’, admits, but experiences Africa working human/elephant con...
Mechanical property of porous nickel-titanium alloy produced by volumetric combustion synthesis (VCS) for bone surgery applications is reported in this paper. Stress-strain behavior of the alloy is determined by uniaxial tension test. Superelastic diagram of the porous alloy is compared with that of the solid material cooled from austenite stability temperature. Due to movements of the dislocat...
The Employee Benefit Research Institute (EBRI) and the Investment Company Institute (ICI) have been collaborating for the past two years to collect data on participants in 401(k) plans. This effort, known as the EBRI/ICI Participant-Directed Retirement Plan Data Collection Project, has obtained data for 401(k) plan participants from certain of EBRI and ICI sponsors and members serving as plan r...
Background and Objectives:Dual media filters have two different layer beds consist of sand and Anthracite. Advantage of dual media filters is longer run duration and more filtration rate. The purpose of this study was to achieve a performable model to improve single media Filters in water treatment plants.Materials and Methods: in this cross-sectional study, two pilots mono and dual media were ...
A study was performed to examine the changes in density of stacked roundwood, chips, and chunks as affected by various compaction treatments. Density of stacked roundwood bolts was tested for the effect of stacking orientation, binding of the stack ends, and species. Stacked bolt wood occupied less than 50 percent of the total rack space for all species, giving final dry bulk densities, based o...
