THE SPRING VARIATION IN TWO DIMENSIONAL MODELING OF RED BLOOD CELL DEFORMABILITY BASED ON GRANULAR

open access: yesSpektra: Jurnal Fisika dan Aplikasinya, 2019
The red blood cell membrane has a complex structure and high deformability. Simulation of that complex red blood cell membrane can simpler use granular-based modeling. Red blood cell is modeled consisting of 50 granular particles connected by springs. An

Hydrographic and hydrochemical characteristics of selected groundwater outflows in desert and semi-desert areas [PDF]

open access: yesJournal of Water and Land Development
The presence of natural groundwater outflows depends on many factors, such as lithology, geological structure, and climate. Areas with particularly poor crenological recognition are arid and semi-arid regions, primarily due to rarity of groundwater ...

Parametric and numerical modeling tools to forecast hydrogeological impacts of a tunnel

open access: yesAcque Sotterranee, 2022
The project of interest involving a hydroelectrical diversion tunnel through a crystalline rock massif in the Alps required a detailed hydrogeological study to forecast the magnitude of water inflows within the tunnel and possible effects on groundwater

Spring technique for correction of multilevel deformity using hexapod external fixator

open access: yesJournal of Limb Lengthening & Reconstruction, 2018
Context: Osteotomies in several parts of one long bone are recommended for correction of a long, curved, and wide-angled deformity. Hexapod external fixators (HEFs) allow for the single-stage correction of multiplanar deformity, but they are heavy ...

An improved model for shield tunnels with double-layer linings and its application in engineering

open access: yesYantu gongcheng xuebao, 2021
An improved model for shield tunnels with double-layer linings is proposed. It can reflect the nonlinear characteristic of bending stiffness of segment joints and the failure mechanism of compression and shear springs between segments and secondary ...

The construction of synthetic maps of groundwater vulnerability on the example of catchment area of Žilůvky stream

open access: yesActa Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2007
The term “vulnerability of groundwater to contamination” was introduced by French hydrogeologist J. Margat in the late 1960s. The idea of describing the degree of vulnerability of groundwater to contaminants as a function of hydrogeological conditions by
