Experimental Study of Evolution of Ice Crystal Size in Turbulent Flow of Ice Slurry

open access: yesZhileng xuebao, 2023
Experiments were conducted with flow rates between 1.0 m/s and 2.5 m/s, ice mass fractions between 10% and 30%, and initial particle sizes between 350 μm and 550 μm to study the effects of these parameters on the evolution of ice crystal size in ice ...

Condoms are more effective when applied by males: a study of young black males in the United States

open access: yes, 2014
PurposeTo determine, among a sample of young black male (YBM), whether female application of male condoms for penile–vaginal intercourse would be associated with higher or lower rates of breakage or slippage.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

open access: yesFEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Experimental analysis of the breakage of a liquid bridge under microgravity conditions. [PDF]

open access: yes, 2011
The experimental results obtained of the experiment \STACO" made on board the Spacelab D-2 Mission are analyzed. The conguration consisted of a liquid bridge between two solid supporting disks. An expected breakage occurred during the experiment.

Clerocidin selectively modifies the gyrase-DNA gate to induce irreversible and reversible DNA damage [PDF]

open access: yes, 2008
Clerocidin (CL), a microbial diterpenoid, reacts with DNA via its epoxide group and stimulates DNA cleavage by type II DNA topoisomerases. The molecular basis of CL action is poorly understood.

Diversity and complexity in neural organoids

open access: yesFEBS Letters, EarlyView.
Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

Stress–Dilatancy For Crushed Latite Basalt

open access: yesStudia Geotechnica et Mechanica, 2018
In this article, the stress–dilatancy relationship for crushed latite basalt is analysed by using Frictional State Theory. The relationship is bilinear, and the parameters α and β determine these two straight lines.

DISCRETE ELEMENT MODELLING OF PARTICLE DEGARDATION OF RAILWAY BALLAST MATERIAL WITH PFC3D SOFTWARE

open access: yesNauka ta progres transportu, 2019
Purpose. It is a very important issue to be able to determine the accurate particle degradation of railway ballast material. There are three different – but connecting – methodology for that: 1) full scale field tests, 2) full scale or reduced scale ...

Organizing the interface—Plasma membrane architecture and receptor dynamics in virus‐cell interactions

open access: yesFEBS Letters, EarlyView.
Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

Breakage of fascial closure device during laparoscopic surgery

open access: yesJournal of Minimal Access Surgery, 2005
Breakage of instruments during laparoscopic surgery is rare. However, when it does occur, locating and retrieving the broken part of the instrument can be cumbersome. Moreover, inability to do so may carry serious medicolegal implications.
