We present a basic formalism for using the Weyl spinor notation in Feynman rules. We focus on Weyl spinors with mixed Dirac and Majorana mass terms. To clarify the definitions we derive the Feynman ...rules from the path integral and present two examples: loop corrections for a fermion propagator and a tree level analysis of a seesaw toy model.

A general standard approach to cardiovascular disease (CVD) prevention is based on patient education and behavior modification. This approach involes an initial CVD risk assessment vist, followed by ...a second visit to discuss findings and recommendations of the assessment. This is followed by 8 additional visits including individual counseling, an 8-week "heart saver" lifestyle program (covering exercise nutrition, and risk factors), and the option of specific educational CVD prevention programs. The approach also utilizes several follow-ups to confirm maintenance of reduced CVD risk. (wz)
