Numerical investigation for influence of pre-twist on stress behavioral characteristics of curved blade

To assist designers in developing blade design based on conventional and composite materials, an overview of material characteristics and stress analysis methods was taken for consideration. The significant effect of loading on the pre-twisted curved blade are evaluated in terms of its deflection and corresponding stresses. A more simplified approach was not satisfactory and furthermore to establish the feasibility of composite blade detailed stress analysis has been carried out for various pre-twist angles of composite and mild steel blade using a thick shell element. The suitability of the finite element method in predicting the stresses in externally loaded laminates is examined from the viewpoint of satisfaction of all boundary conditions and results. From the results it can be shown that the three-dimensional finite element analysis provides a useful insight for predicting deflection and stresses. The influence of ply angle for the distribution of inter laminar stresses along y and z-axis are determined

Intrathecal baclofen in management of a patient with very severe tetanus

Tetanus is uncommon in developed countries. The majority of tetanus cases occur in third world countries and 50% of these cases occur in neonates. There are more than 800,000 deaths due to tetanus each year in the world. We present a case of 40-year-old male patient diagnosed to have very severe tetanus - Grade IV as per Ablett classification of severity, managed in our hospital with aggressive treatment for 27-days and use of intrathecal baclofen he showed drastic improvement in this status.  He was discharged in neurological intact conditions with hemodynamic stability.
