Pulsatile cerebral paraarterial flow by peristalsis, pressure and directional resistance
Abstract Background A glymphatic system has been proposed that comprises flow that enters along cerebral paraarterial channels between the artery wall and the surrounding glial layer, continues through the parenchyma, and then exits along similar paravenous channels. The mechanism driving flow…

Similitude for buildings conditioned entirely by ambient energy
While whole-building dynamic simulation programs can accurately predict indoor comfort in buildings conditioned by ambient energy (from the sun, sky, air, and ground), skill and time requirements represent a barrier to their widespread use. Simplified design tools present opportunities to establish…

Is bulk flow plausible in perivascular, paravascular and paravenous channels?
Abstract Background Transport of solutes has been observed in the spaces surrounding cerebral arteries and veins. Indeed, transport has been found in opposite directions in two different spaces around arteries. These findings have motivated hypotheses of bulk flow within these spaces. The…

Dispersion in porous media in oscillatory flow between flat plates: applications to intrathecal, periarterial and paraarterial solute transport in the central nervous system
Abstract Background As an alternative to advection, solute transport by shear-augmented dispersion within oscillatory cerebrospinal fluid flow was investigated in small channels representing the basement membranes located between cerebral arterial smooth muscle cells, the paraarterial space…

In vitro and numerical simulation of blood removal from cerebrospinal fluid: comparison of lumbar drain to Neurapheresis therapy
Abstract Background Blood removal from cerebrospinal fluid (CSF) in post-subarachnoid hemorrhage patients may reduce the risk of related secondary brain injury. We formulated a computational fluid dynamics (CFD) model to investigate the impact of a dual-lumen catheter-based CSF filtration system…

Ambient energy for buildings: Beyond energy efficiency
The following Key Messages comprise the salient findings of this study:1. Ambient energy (from sun, air, ground, and sky) can heat and cool buildings; provide hot water, ventilation, and daylighting; dry clothes; and cook food. These services account for about three-quarters of building energy…
