Oscillatory-Flow PCR Microfluidic Chip Driven by Low Speed Biaxial Centrifugation [PDF]
Biosensors, 2023 PCR is indispensable in basic science and biotechnology for in-orbit life science research. However, manpower and resources are limited in space. To address the constraints of in-orbit PCR, we proposed an oscillatory-flow PCR technique based on biaxial ...

Entrainment of Lymphatic Contraction to Oscillatory Flow [PDF]
Scientific Reports, 2019 AbstractLymphedema, a disfiguring condition characterized by an asymmetrical swelling of the limbs, is suspected to be caused by dysfunctions in the lymphatic system. A possible source of lymphatic dysfunction is the reduced mechanosensitivity of lymphangions, the spontaneously contracting units of the lymphatic system.

KCa3.1 Inhibition Decreases Size and Alters Composition of Atherosclerotic Lesions Induced by Low, Oscillatory Flow [PDF]
Artery Research, 2021 Low, oscillatory flow/shear patterns are associated with atherosclerotic lesion development. Increased expression of KCa3.1 has been found in Vascular Smooth Muscle (VSM), macrophages and T-cells in lesions from humans and mice.

Non‐invasive cardiac power measurements in decompensated heart failure in elderly adults: A prospective proof‐of‐concept study [PDF]
Physiological ReportsIn this proof‐of‐concept study, we evaluated the feasibility of non‐invasive estimation of cardiac power metrics—total power, steady power, oscillatory power, and oscillatory power fraction—and compared the prognostic and diagnostic value with ...

Numerical Study on the Non-Oscillatory Unstarted Flow in a Scramjet Inlet-Isolator Model
Aerospace, 2022 For successful scramjet engine operations, it is important to understand the mechanism of the inlet unstart phenomenon. Among various unstarted flow patterns in hypersonic inlets, the mechanism of low-amplitude oscillatory unstarted flow is still unclear.

Hovering in oscillatory flows [PDF]
Journal of Fluid Mechanics, 2016 We investigate the hovering dynamics of rigid bodies with up-down asymmetry placed in oscillating background flows. Recent experiments on inanimate pyramid-shaped objects in oscillating flows with zero mean component demonstrate that the resulting aerodynamic forces are sufficient to keep the object aloft.

The Half-Range Moment Method in Harmonically Oscillating Rarefied Gas Flows
Fluids, 2021 The formulation of the half-range moment method (HRMM), well defined in steady rarefied gas flows, is extended to linear oscillatory rarefied gas flows, driven by oscillating boundaries.

Oscillatory Flow Near a Stagnation Point [PDF]
SIAM Journal on Applied Mathematics, 2003 The authors consider an unsteady version of classical Hiemenz solution describing incompressible two-dimensional stagnation point flow at a solid wall, examining particularly the response close to the wall when the solution at infinity is modulated in time by a periodic factor of specified amplitude and frequency for arbitrary values of these ...

The Improving the Thermal Performance of a Heat Exchanger using a New Passive Technology
Tikrit Journal of Engineering Sciences, 2023 In this study, the oscillation technique was applied in a multi-tube heat exchanger with baffles. The Nusselt number was investigated in the heat exchanger (HE) over a wide range of operating conditions, Reynolds number (Re =205-3200), and oscillatory ...
