Laser-triggered ion acceleration and table top isotope production
We have observed deuterons accelerated to energies of about 2 MeV in the interaction of relativistically intense 10 TW, 400 fs laser pulse with a thin layer of deuterated polystyrene deposited on Mylar film. These high-energy deuterons were directed to the boron sample, where they produced ~105 atoms of positron active isotope 11C from the reaction 10B(d,n)11C. The activation results suggest that deuterons were accelerated from the front surface of the target

These high-energy deuterons were directed to the boron sample, where they produced ∼ 105∼105 atoms of positron active isotope 11C11C from the reaction 10B(d,n)11C.10B(d,n)11C. The activation results suggest that deuterons were accelerated from the front surface of the target. © 2001 American Institute of Physics.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/70713/2/APPLAB-78-5-595-1.pd
Study of Energetic Ion Generation from High-Intensity-Laser Dense-Plasma Interactions
We report on the characteristics of an ultrafast-laser driven proton beam from thinfilm targets. The difference in proton beam profiles, beam energies, and laser induced back ablation plumes between a dielectric (Mylar) and a conductor (aluminum) are discussed. Evidence for front-side acceleration and a method for beam manipulation are also presented
Business ethics : practical proposals
While most people agree that the inculcation of ethical awareness is desirable, the means of stimulating this awareness vary among companies, industries and cultures. The fundamental question surrounding the difference between social responsibility and ethics is addressed. Guidelines for establishing ethical priorities from both the individual, group and organisational perspectives are provided. <br /
Building Field-Based Ecophysiological Genome-to-Phenome Prediction
Feeding the estimated global population of 9 billion persons by 2050 will require a doubling of the food supply. However, the annual yield
rates of gain for major grain crops is only one-quarter to one half of that which is necessary to reach this target. Remedying this deficit necessitates
drastic improvements in the ability to predict crop field behavior based on its genetics and the growth environment. This is critical both for breeding
programs and for efficient management in farmers’ fields after new varieties are released. This project aims to increase the capacity of Kansas and
Oklahoma to conduct research on quantitative prediction methodologies using wheat as a model crop plan
