13. Estudo do comportamento mecanico de comandos desbalanceados pelo metodo de elementos finitos
The work treats the finite element modeling of the static behaviour of drillstrings equiped with bottom hole assemblies composed by unbalanced drill collars. The drillstring was discretized in beam-column elements having geometric non linearity. The Newton-Raphson Method with an incremental loading scheme was used to obtain the solution of the non linear sys

15. Measurement of inspiratory muscle performance with incremental threshold loading: a comparison of two techniques.
BACKGROUND--Incremental threshold loading (ITL) is a test of inspiratory muscle performance which is usually performed by breathing through a weighted inspiratory plunger, the load on the inspiratory muscles being increased by externally adding weights to the intake valve. This is not a true threshold device and may be inaccurate. This method was compared wi

16. High endogenous calcium buffering in Purkinje cells from rat cerebellar slices.
1. The ability of Purkinje cells to rapidly buffer depolarization-evoked intracellular calcium changes (delta [Ca2+]i) was estimated by titrating the endogenous buffer against incremental concentrations of the Ca(2+)-sensitive dye fura-2. 2. In cells from 15-day-old rats, pulse-evoked delta [Ca2+]i were stable during the loading with 0.5 mM fura-2 through th

17. Coronary artery disease in patients requiring abdominal aortic aneurysm repair. Selective use of a combined operation.
The chief cause of operative mortality after abdominal aortic aneurysm (AAA) repair is myocardial infarction. For this reason, routine coronary angiography followed by prophylactic coronary artery bypass grafting (CABG) prior to AAA repair has been recommended by some surgeons. We report here the results of the selective use of a combined operation. Two hund
