Eliminating artificial trans fatty acids in Argentina: estimated effects on the burden of coronary heart disease and costs

Abstract Objective To estimate the impact of Argentine policies to reduce trans fatty acids (TFA) on coronary heart disease (CHD), disability-adjusted life years (DALYs) and associated health-care costs.Methods We estimated the baseline intake of TFA before 2004 to be 1.5% of total energy intake.We built a policy model including baseline intake of

In-service fatigue cracking of the propeller shafts joined by a spline-pinned construction to the engines of AN-24, AN-26, and IL-18 aircrafts

The paper delivers a critical review of the research data on the crack initiation and crack growth patterns characteristic of the components of the spline-bolted joints between the propeller shaft and reducer shaft at An-24, An-26, and Il-18 aircrafts.Cracks in the shafts Hook and Loop Strapping nucleated because of reduced bolt-fastening force.Act
