Advances in seismic imaging of mantle transition zone discontinuities

open access: yes地球与行星物理论评, 2023
Located between the 410-km and 660-km discontinuities, the mantle transition zone is the key region for understanding the thermal and chemical structure and the dynamic evolution of the Earth’s mantle.

Diversity Patterns and Community Structure of the Ground-Associated Macrofauna along the Beach-Inland Transition Zone of Small Tropical Islands

open access: yesDiversity, 2021
Biodiversity follows distinct and observable patterns. Where two systems meet, biodiversity is often increased, due to overlapping occurrence ranges and the presence of specialized species that can tolerate the dynamic conditions of the transition zone ...

On transition-zone water clouds [PDF]

open access: yesAtmospheric Chemistry and Physics, 2014
A recent field campaign was conducted to measure the properties of thin, warm convective clouds forming under conditions of weak updrafts. During the campaign, short-lived clouds (on the order of minutes) with droplets' effective radius of 1–2 μm and low

The Role of Multi-wall Carbon Nanotubes on Fracture Mechanism of Epoxy Nanocomposite [PDF]

open access: yesعلوم و تکنولوژی پلیمر, 2008
In order to investigate the role of multi-wall carbon nanotubes (MWCNTs) on fracture mechanism of epoxy nanocomposites, a series of tensile standard specimens reinforced with different carbon nanotube contents (0, 0.3, 0.6 and 1 wt%) were produced.

Komatiites From Mantle Transition Zone Plumes

open access: yesFrontiers in Earth Science, 2020
During the Archean, episodic volcanism commonly included both plume- and arc-type magmatism, raising the issue of a possible link between “bottom up” and “top down” geodynamic processes.

Life-Saver or Undertaker: The Relationship between Primary Cilia and Cell Death in Vertebrate Embryonic Development

open access: yesJournal of Developmental Biology, 2022
The development of multicellular organisms requires a tightly coordinated network of cellular processes and intercellular signalling. For more than 20 years, it has been known that primary cilia are deeply involved in the mediation of intercellular ...

Finite Element Modeling of the Dynamic Response of Critical Zones in a Ballasted Railway Track

open access: yesFrontiers in Built Environment, 2021
The critical zones are the discontinuities along a railway line that are highly susceptible to differential settlement, due to an abrupt variation in the support conditions over a short span.

Root Apex Transition Zone as Oscillatory Zone

open access: yesFrontiers in Plant Science, 2013
Root apex of higher plants shows very high sensitivity to environmental stimuli. The root cap acts as the most prominent plant sensory organ; sensing diverse physical parameters such as gravity, light, humidity, oxygen and critical inorganic nutrients ...

Analysis of Near-Cloud Changes in Atmospheric Aerosols Using Satellite Observations and Global Model Simulations

open access: yesRemote Sensing, 2021
This paper examines cloud-related variations of atmospheric aerosols that occur in partly cloudy regions containing low-altitude clouds. The goal is to better understand aerosol behaviors and to help better represent the radiative effects of aerosols on ...

Synergy Effect of Factors Characterising Village Transition Zones on Speed Reduction

open access: yesEnergies, 2021
There are various traffic calming measures that can be installed in village transition zones. So far, focus was placed on diversified use of pavement markings, amounts of horizontal deflection, shape of the installed chicanes or central islands, presence
