The meaning of effective soil parameters for determining of the bearing capacity of cohesive soils

open access: yesBudownictwo i Architektura, 2014
The paper presents the analysis of the bearing capacity of cohesive soils, which was calculated based on the PN-EN-1997-1 methodology. This computations take into account the effect of pore water pressure on the soil strength parameters.

Laboratory study on the effects of hydraulic and granulometric parameters on the response of granular soil to internal erosion [PDF]

open access: yes, 2019
Erosion is a major environmental problem to agricultural land as well as to civil engineering infrastructures. Rainwater infiltration into granular soils can lead to the migration of fine particles by suffusion.

A New Era for Using Natural Pigments: The Case of the C50 Carotenoid Called Bacterioruberin

open access: yesBiotechnology and Applied Biochemistry, EarlyView.
ABSTRACT Haloarchaea are extremophilic microorganisms belonging to the Archaea domain that require high salt concentrations to live, thus inhabiting ecosystems like salty ponds, salty marshes, or extremely salty lagoons. They are more abundant and widely distributed worldwide than initially expected.

A physically-based bank erosion model for composite river banks: Application to Mackinaw River, Illinois [PDF]

open access: yes, 2013
Meandering river migration over large spatial and temporal scales has traditionally been numerically simulated using a bank erosion submodel that calculates the eroding bank migration rate as the product of the near-bank excess flow velocity and a ...

Fluid - Structure - Soil Interaction of Cylindrical Liquid Storage Tank Subjected to Horizontal Earthquake Loading [PDF]

open access: yes, 2019
Shallow founded tanks are strategic structures used to store a variety of kind of liquids. The fluid develops hydrodynamic effect on solid domain of container during an earthquake. This paper provides the theoretical background for numerical model on

Activism as education in and through the youth climate justice movement

open access: yesBritish Educational Research Journal, EarlyView.
Abstract Young people worldwide are increasingly participating in a global movement for climate justice, yet to date, little research has examined how youth climate justice activists conceive of and experience activism as education. The present study used in‐depth, semi‐structured interviews with 16 US climate justice activists (aged 15–17) to address ...
