A continuous/discontinuous Galerkin formulation for a strain gradient-dependent damage model [PDF]

open access: yes, 2004
The numerical solution of strain gradient-dependent continuum problems has been hindered by continuity demands on the basis functions. The presence of terms in constitutive models that involve gradients of the strain field means that the $C^0$ continuity

Optimization of The Cell Aggregates Method for Isolation and Purification of Human Granulosa Cells from Follicular Fluid [PDF]

open access: yesInternational Journal of Fertility and Sterility, 2020
Background Aspirated ovarian follicular fluids (FF) contain luteal granulosa cells (LGCs) and other contaminating cell types. Several strategies, such as the antibody binding methods, the flask method, the cell strainer and positive selection of ...

3D Correlative Imaging of Lithium Ion Concentration in a Vertically Oriented Electrode Microstructure with a Density Gradient

open access: yesAdvanced Science, 2022
The performance of Li+ ion batteries (LIBs) is hindered by steep Li+ ion concentration gradients in the electrodes. Although thick electrodes (≥300 µm) have the potential for reducing the proportion of inactive components inside LIBs and increasing ...

Using spatial distance sampling models to optimize survey effort and address violations of the design assumption

open access: yesEcological Solutions and Evidence, 2021
Conventional distance sampling approaches rely on the design assumption (i.e. uniform distribution of individuals in relation to transects) to ensure unbiased inference to the population of interest.

Does choosing microfluidics for sperm sorting offer an advantage to improve clinical pregnancies in donor egg recipients?

open access: yesJournal of Human Reproductive Sciences, 2022
Background: Microfluidics (MF), an advanced sperm sorting technology results in the extraction of spermatozoa with higher DNA integrity and lower DNA damage compared to existing conventional sperm sorting methods. Aims: The aim of the present study is to

Continuous Percoll Gradient Centrifugation of Erythrocytes—Explanation of Cellular Bands and Compromised Age Separation

open access: yesCells, 2022
(1) Background: When red blood cells are centrifuged in a continuous Percoll-based density gradient, they form discrete bands. While this is a popular approach for red blood cell age separation, the mechanisms involved in banding were unknown.

Spira mirabilis enhanced density gradient centrifguation [PDF]

open access: yes, 2013
The centrifugal microfluidic “lab-on-a-disc” paradigm is particularly suited to the pre-conditioning of whole blood. In this work we define the geometry of sedimentation chambers using the Spira Mirabilis (equiangular spiral) and so enhance the ...

ASSESSMENT OF GAS-HYDROTHERMAL ACTIVITY OF THE BAIKAL RIFT IN THE LAKE AREA FROM NUMERICAL EXPERIMENT DATA

open access: yesГеодинамика и тектонофизика, 2015
The Baikal rift is characterized by high heat flow, seismic activity and large thickness of sediments through which gas and hydrothermal water are intensely released into the lake water.
