The problem of large deflection of a rectangular plate resting on a Pasternak-type foundation and subjected to a uniform lateral load has been investigated by utilizing the linearized equation of plates due to H. M. Berger. The solutions derived and based on the effect of the two base parameters have been carried to practical conclusions by presenting graphs for bending moments and shear forces for a square plate with all edges simply supported.

AbstractObjective:To report the results of our preintervention investigation and subsequent 19-month three-phase intervention study designed to reduce pyrogenic reactions among patients undergoing cardiac catheterization using reprocessed catheters.Design:A case-control study for the preintervention period and a prospective cohort study for the intervention period.Setting:A 400-bed hospital in Belo Horizonte, Brazil.Participants:Any patient undergoing cardiac catheterization in the hospital.Interventions:Three intervention phases were implemented to improve the quality of the water supplied to the cardiac catheter reprocessing laboratory. Standard operating procedures for reprocessing cardiac catheters were established and reprocessing staff were trained and educated.Results:The rate of pyrogenic reactions decreased significantly during the intervention phases, from 12.8% (159 of 1,239) in phase 1 to 5.3% (38 of 712) in phase 2 to 0.5% (4 of 769) in phase 3 (chi-square test for linear trend, 97.5;P< .001).Conclusion:Improving water quality and using standard operating procedures for reprocessing catheters can prevent pyrogenic reactions in hospitalized patients.
