BACKGROUND Throughout the course of their illness, people with amyotrophic lateral sclerosis (ALS) must make many treatment decisions; however, none has such a significant impact on quality of life and survival as decisions about assisted ventilation. OBJECTIVE The purpose of this study was to better understand the experience of decision-making about assisted ventilation for ALS patients. M...

We study a scattering-assisted second harmonic generation process of a structured fundamental wave, whose phase front is periodically modulated, in a homogenous nonlinear medium. Scattering-assisted multiple-conical second harmonic in a one-dimensional structured fundamental wave and second harmonic belts in two-dimensional cases were observed. The experimental results are consistent with our a...

We present calculations for the oscillator strength of the recombination of excitons bound to phosphorus donors in silicon. We show that the direct recombination of the bound exciton cannot account for the experimentally measured oscillator strength of the no-phonon line. Instead, the recombination process is assisted by an Umklapp process of the donor electron state. We make use of the empiric...

52 Physician Assisted Suicide: An Exploration of the Dying Process Kunwar Kaur Abstract Up until about two decades ago, the practice of physician-assisted suicide was prohibited in the United States. However, the issues surrounding the legalization of physicianassisted suicide have long been the topic of debate as proponents seek to change public policy. Just as keenly, though, the opposition s...

In the present study, ultrasound-assisted extraction of oil from rice bran was investigated through response surface methodology (RSM), where process variables were amplitude level (50–100%) and sonication time (5-30 min). It was found that all process variables had significant (p<0.05) effects on the response variable. A central composite design (CCD) was used to determine the optimum process ...
