The stability of the embankment’s slopes is a critical aspect geotechnical engineering and it essential to guarantee effectiveness factor safety prevent any potential failures in slope both during post-construction. current study consists two parts; first part behavior geogrid-encased granular columns their interaction with soil at shear surface generated by slippage soil, while second changing...

The paper proposes moral and ethical guidelines for medical treatment at the edge of viability. The proposed principles are defended on the grounds of a general conceptual framework presented by elucidating the notions of viability, the edge of viability, person, sanctity of human life, dignity, and the slope of dignity protection, as well as the distinction between ethics and morality.

The application of the following new indices of the efficacy of antidotes has been substantiated and discussed: the "antidotal potency" as a ratio of LD50 of a poison when an antidote used to LD99 in control intact animals, and the "index of solid protection" as a ratio of LD10 in the experiments to LD90 in controls. The two indices are true for changing the lethality curve slope, which makes i...
