Influence of the grain size and the fluid viscosity on the collapse of submerged sand columns

open access: yes, 2022
Granular flows are ubiquitous in natural phenomena and are also used in various industrial applications. Nonetheless, they exhibit counter-intuitive behaviour as well as complex rheological behaviour, making them challenging to fully understand and model.

Non-Linear Creep of Spherical Container with Fluid Under Increasing Pressure

open access: yesEngineering Proceedings
This paper presents an analysis of the time-dependent response of a spherical container to internal pressure that increases over time. The wall of the container is relatively thin, in the sense that the wall thickness is negligible in comparison to the ...

Intelligence, age and schooling: data from the Battery of Reasoning Tests (BRT-5) Inteligência, idade e escolarização: dados da Bateria de Provas de Raciocínio (BPR-5)

open access: yesPsicologia: Reflexão e Crítica, 2012
Intelligence is commonly divided into two distinctive areas: fluid intelligence (Gf), which is understood as the skill of reasoning or intelligence as a process, and crystallized intelligence (Gc) that involves skills that are more related to learning ...

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis

open access: yesFEBS Letters, EarlyView.
Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.

FLUIDIZATION OF A BED OF SOLID PARTICLES IN A TWO DIMENSIONAL VERTICAL BOX

open access: yesSpektra: Jurnal Fisika dan Aplikasinya, 2019
Simulation of fluidization of a bed of solid particles in a two-dimensional box is performed using molecular dynamics methods by assuming that superposition of buoyant, gravitational, viscous, collision force will make the particle to move in two ...

Diuretic responses to Ringer's solution and 20% albumin at different arterial pressures

open access: yesPhysiological Reports
Intravenous volume loading is a common treatment when hypovolemia is a potential cause of oliguria. We studied whether the effectiveness of Ringer's solution and 20% albumin in inducing diuresis differs depending on the mean arterial pressure (MAP).
