This paper presents new research in the field of nonlinear static seismic analysis and N2 method for soil-structure systems. The rationale this study stems from inclusion systems simplified displacement-based design methods. conducted comprises three parts, including original experimental investigations, development numerical models validation results. A methodology is presented that provides a...

leishmaniases are a group of sand fly-borne diseases caused by protozoan parasites from species of leishmania genus. these diseases are reported in about 100 countries with a prevalence of 12 million people infected and incidence of 2 million people per year, putting approximately 350 million people at risk of the infections. leishmaniases are endemic and are considered as important public heal...

Design of blast resistant structures is an important subject in structural engineering, attracting the attention of governments, researchers, and engineers. Thus, given the benefits of optimization in engineering, development and assessment of optimization methods for optimum design of structures against blast is of great importance. In this research, multi-objective optimization of steel momen...

Sand dripping in 1 dimensional Sand Pile Model is rst studied. Patterns and signals appear. Their behaviors and interactions are explained and asymptotic approximations are made. The total collapsing time of a single stack of sand is linear in function of the number of grains.

The addition of charcoal (or biochar) to soil has significant carbon sequestration and agronomic potential, making it important to determine how this potentially large anthropogenic carbon influx will alter ecosystem functions. We used column experiments to quantify how hydrologic and nutrient-retention characteristics of three soil materials differed with biochar amendment. We compared three h...
