Cardiac ventricular performance in the appropriate‐ for‐gestational age and small‐for‐gestational age fetus: relation to regional cardiac non‐uniformity and peripheral resistance [PDF]

Ultrasound in Obstetrics & Gynecology, 2002
AbstractObjectiveTo investigate the relationship between parameters of diastolic function, loading conditions and remodeling of the left ventricle in the appropriate‐for‐gestational age and small‐for‐gestational age fetus.MethodsTwo‐dimensional echocardiographic left ventricular images were digitized in 24 appropriate‐for‐gestational age and 14 small ...

Mitigation of mismatch power loss in aged photovoltaic arrays following a comparative investigation into module rearrangement techniques

Energy Reports, 2022
Power degradation due to non-uniform aging is a common phenomenon in large photovoltaic array systems. Aging increases the current–voltage mismatch in the array modules that results in mismatch power loss in the array.

Expanding the agenda for research on the physically active aging body

, 2009
In this article, the authors consider the different approaches that can be used to examine the relationship between physical activity and aging. They propose that much is to be gained in our awareness of this dynamic relationship by drawing on multiple ...

Aging Alters Daily and Regional Calretinin Neuronal Expression in the Rat Non-image Forming Visual Thalamus

, 2021
Aging affects the overall physiology, including the image-forming and non-image forming visual systems. Among the components of the latter, the thalamic retinorecipient inter-geniculate leaflet (IGL) and ventral lateral geniculate (vLGN) nucleus conveys ...

Aging as a consequence of misrepair -- A novel theory of aging

, 2009
It is now increasingly realized that the underlying mechanisms which govern aging is a complex interplay of genetic regulation and damage accumulation. Aging as a result of accumulation of ‘faults’ on cellular and molecular levels, has been

Anti-inflammatory and anti-aging activity of hydrogel with active ingredient Phyllantus emblica L. fruit nanosimplicia [PDF]

Journal of Medicinal Plants, 2023
Background: Phyllantus emblica contains quite high levels of vitamin C as an antioxidant, premature aging and anti-inflammatory. Simplicia is formulated into a hydrogel because it has good dispersion power on the skin.

Plankton response to global warming is characterized by non-uniform shifts in assemblage composition since the last ice age

Nature Ecology & Evolution, 2022
AbstractBiodiversity is expected to change in response to future global warming. However, it is difficult to predict how species will track the ongoing climate change. Here we use the fossil record of planktonic foraminifera to assess how biodiversity responded to climate change with a magnitude comparable to future anthropogenic warming.

Non-Destructive Detection of Local Aging in Lithium-Ion Pouch Cells by Multi-Directional Laser Scanning

, 2017
Understanding the mechanical activity of lithium-ion cells during cycling and its connection with aging phenomena is essential to improve cell design and operation strategies. Previous studies of lithium-ion pouch cells [B.

Grading ring parameters optimization for 220 kV metal‐oxide arrester using 3D‐FEM method and bat algorithm

IET Science, Measurement & Technology, 2021
Aging of metal oxide surge arresters is mainly affected by the high electric stress near the high voltage electrode. It has been observed that the distribution of voltage and electric field along an arrester is non‐uniform.
