Contrasts or Carryover? Demands–Capabilities Fit and Task‐Level Intrinsic Motivation Across the Workday

open access: yesJournal of Organizational Behavior, EarlyView.
ABSTRACT In the course of a workday, employees attend to various tasks whose challenge might be equal to, higher than, or lower than employees' present level of capabilities. Moreover, employees encounter these tasks sequentially throughout the day with different levels of prior motivation. Investigating carryover effects in motivation from one task to

On the Stokes number and characterization of aerosol deposition in the respiratory airways [PDF]

open access: yes, 2015
Aerosol deposition in the respiratory airways has traditionally been examined in terms of the Stokes number based on the reference flow timescale. This choice leads to large scatter in deposition efficiency when plotted against the reference Stokes ...

A monolithic fluid-structure interaction formulation for solid and liquid membranes including free-surface contact

open access: yes, 2018
A unified fluid-structure interaction (FSI) formulation is presented for solid, liquid and mixed membranes. Nonlinear finite elements (FE) and the generalized-alpha scheme are used for the spatial and temporal discretization.

Numerical simulation of a wawe generator: a case of study [PDF]

open access: yes, 2013
The aim of present work is the numerical simulation of a linear generator, capable of directly converting the kinetic energy, available by the wave, into electrical energy, through the device linear motion (up and down).

AutoChamber: A broadly accessible 3D‐printed floating chamber to automate measurements of greenhouse gas emissions from surface waters

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Fresh waters provide environmental conditions that favour microbial CO2 and CH4 production, leading to the release of large quantities of greenhouse gases (GHG) to the atmosphere. Despite their importance, these fluxes remain poorly defined, weakening estimates of global GHG budgets that are critical in implementing effective climate ...

Fluid structure interaction with curved space lattice Boltzmann

open access: yes, 2018
We present a novel method for fluid structure interaction (FSI) simulations where an original 2nd-order curved space lattice Boltzmann fluid solver (LBM) is coupled to a finite element method (FEM) for thin shells.

Pig Seminal Plasma Extracellular Vesicles Enhance Motility During Preservation of Epididymal Spermatozoa but Impair Capacitation and IVF Parameters

open access: yesAndrology, EarlyView.
ABSTRACT Background Extracellular vesicles (EVs) produced by accessory sex glands play a key role in sperm functionality, influencing motility, viability, acrosome integrity, metabolic activity, and capacitation. Most studies on the effects of EVs on spermatozoa have focused on ejaculated spermatozoa, which have already been exposed to their own native

The plasticisation model of dye diffusion: Part 7

open access: yesColoration Technology, EarlyView.
Abstract Re‐evaluation using the Williams‐Landel‐Ferry equation, of exhaustion/fixation/adsorption data previously reported for four classes of anionic dye onto three different types of wool substrate, revealed that thermally activated dyeing/desorption behaviour is governed by the thermally regulated structural relaxation times of the respective water‐

A reference solution of the flow over a circular cylinder at Re=40

open access: yes, 2013
The classical problem of the flow over a circular cylinder at Reynolds number 40 is considered using an accurate pseudo-spectral code. A new set of boundary conditions is proposed to improve the representation of the infinite flow domain, especially in ...
