Plasma free fatty acid (FFA) kinetics in humans are often measured with only one tracer. In study 1, healthy volunteers received infusions of [U-¹³C]linoleate, [U-¹³C]oleate, and [U-¹³C]palmitate during continuous feeding with liquid meals low (n = 12) and high (n = 5) in palmitate and containing three labeled fatty acids to measure FFA appearance and fractional spillover of lipoprotein lipase-...

As Internet access grows at different rates across regions, the Internet has had variable effects on regional economies through agglomeration and spillover effects. This paper uses province-level panel data from 2000 to 2013 to study inequality in Internet access, its spatial effect on regional economies in China and the channels through which the spillover effects are most evident. We find tha...

Experiments reported herein document heterogeneous crystal nucleation on bubbles in supercooled lithium disilicate melt. Crystalline lithium disilicate (Li2Si2O5) nucleated and grew on small bubbles (;1 mm) with a one-to-one correspondence between the number of bubbles and crystals (ranging from ,102 to ;105 bubbles/mm3). Crystals grew on large bubbles (.100 mm) only in samples fused in N2, sug...

This report presents a review of the literature that underpins the different pathways through which the transition between two pro-environmental behaviours can occur. Its primary aim is to inform the theoretical part of a 2012 linkage project grant application for the Australian Research Council to be submitted by BehaviourWorks Australia. A special emphasis is on research where interventions h...

If a union successfully organizes one plant, does it make it easier to organize other nearby plants? If the answer is yes, there is a spillover effect from one plant to the next. If spillovers are important, then when a union gets it foot in the door and organizes some initial plants, unionism may spread like a contagion and turn a city into what trade unionists call a “union town.” The purpose...

In wet liquid foams, slow diffusion of gas through bubble walls changes bubble pressure, volume and wall curvature. Large bubbles grow at the expenses of smaller ones. The smaller the bubble, the faster it shrinks. As the number of bubbles in a given volume decreases in time, the average bubble size increases: i.e. the foam coarsens. During coarsening, bubbles also move relative to each other, ...

BACKGROUND Evolution of a gas injected in a liquid is analyzed using the example of the behavior of oxygen molecules in water in which bubbles of gas molecules grow slowly by attachment of gas molecules to bubbles, the bubbles then associate and finally flow up to the liquid-gas interface and pass into the gas phase. RESULTS Two methods are considered for gas injection in a liquid, insertion ...

The oxygen evolution reaction generally exists in electrochemical reactions. It is a ubiquitous problem about how to control the motion of oxygen bubbles released by the reaction. Here we show that oxygen bubbles during oxygen evolution reaction exhibit a variety of movement patterns in the magnetic field, including directional migration and rotational motion of oxygen bubbles when the magnet i...

The dynamics of bubbles at high Reynolds numbers is studied from the viewpoint of statistical mechanics. Individual bubbles are treated as dipoles in potential flow. A virtual mass matrix of the system of bubbles is introduced, which depends on the instantaneous positions of the bubbles, and is used to calculate the energy of the bubbly flow as a quadratic form of the bubbles’ velocities. The e...

We demonstrate that thermocapillary forces may drive bubbles against liquid flow in 'anomalous' mixtures. Unlike 'ordinary' liquids, in which bubbles migrate towards higher temperatures, we have observed vapour bubbles migrating towards lower temperatures, therefore against the flow. This unusual behaviour may be explained by the temperature dependence of surface tension of these binary mixture...
