this paper presents a simplified approach to estimate the resultant force, which should be provided by a retention system, for the equilibrium of unstable slopes. the results were obtained with a developed algorithm, based on limit equilibrium analyses, that assumes a two-part wedge failure mechanism. design charts to obtain equivalent earth pressure coefficients are presented. based on the res...

in this paper we investigate the behavior of solutions, stable and unstable of the solutions a second-order rational difference equation. also we will discuss about the behavior of solutions a the rational system, we show these solutions may be stable or unstable.

C-reactive protein (CRP) response was studied in 44 patients with acute angina pectoris admitted to the coronary care unit. 71 % of patients with acute myocardial infarction (MI)had positive CRP test while 73% of patients presumed to have unstable angina pectoris had negative CRP test. This test can be helpful in differentiating between acute MI and unstable angina pectoris.
