A Genre Analysis of Science and Technology Scopus-Indexed Journal Articles: Does Impact Factor Project Different Rhetorical Moves?

open access: yesJL3T (Journal of Linguistics, Literature and Language Teaching), 2023
Productivity in conducting research and publishing articles is the obligation of lecturers as academics. However, due to their failure to follow international writing conventions, they have difficulties in writing for international publications.

THE NEPSKY-1 IMPACT CRATER AND ITS FILL DEPOSITS ON THE BASEMENT ROOF OF THE SIBERIAN PLATFORM

open access: yesГеодинамика и тектонофизика, 2020
In the Earth studies, discoveries and investigations of impact craters buried beneath thick sediments are sporadic so far and may still remain inefficient, unless geophysical surveys of the areas of interest are initiated. Such studies can provide useful

Terrestrial Impact Structures [PDF]

open access: yesAnnual Review of Earth and Planetary Sciences, 1987
Impact structures are the dominant landform on planets that have retained portions of their earliest crust. The present surface of the Earth, however, has comparatively few recognized impact structures. This is due to its relative youthfulness and the dynamic nature of the terrestrial geosphere, both of which serve to obscure and remove the impact ...

Impact of community structure on information transfer [PDF]

open access: yes, 2008
The observation that real complex networks have internal structure has important implication for dynamic processes occurring on such topologies. Here we investigate the impact of community structure on a model of information transfer able to deal with ...

Impact structures in Africa: A review

open access: yesJournal of African Earth Sciences, 2014
More than 50 years of space and planetary exploration and concomitant studies of terrestrial impact structures have demonstrated that impact cratering has been a fundamental process - an essential part of planetary evolution - ever since the beginning of accretion and has played a major role in planetary evolution throughout the solar system and beyond.

In situ U–Pb analysis of shocked zircon from the Charlevoix impact structure, Québec, Canada

open access: yesMeteoritics and Planetary Science, 2019
Laser ablation inductively coupled plasma‐mass spectrometry (LA‐ICP‐MS) U–Pb geochronology of shocked zircon grains in a vesicular‐fluidal impact melt rock from the ≥54 km Charlevoix impact structure, Québec, Canada, suggests an Ordovician to Silurian ...

Numerical and Theoretical Modeling of Droplet Impact on Spherical Surfaces [PDF]

open access: yesPhysics of Fluids 33, 052112 (2021), 2020
Droplet impact on solid surfaces is a fluid phenomenon widely involved in additive manufacturing, heat management, and coating, in which the ability to exert control over the impact dynamics and duration is critical. While past studies have established a comprehensive understanding of the impact on flat substrates, what we know about the impact ...

Impact‐Induced Porosity and Microfracturing at the Chicxulub Impact Structure

open access: yesJournal of Geophysical Research: Planets, 2019
Porosity and its distribution in impact craters has an important effect on the petrophysical properties of impactites: seismic wave speeds and reflectivity, rock permeability, strength, and density.

Titanium Dioxide: Structure, Impact, and Toxicity

open access: yesInternational Journal of Environmental Research and Public Health, 2022
Titanium dioxide, first manufactured a century ago, is significant in industry due to its chemical inertness, low cost, and availability. The white mineral has a wide range of applications in photocatalysis, in the pharmaceutical industry, and in food ...

Impact of Dynamical Fermions on QCD Vacuum Structure [PDF]

open access: yes, 2008
We examine how dynamical fermions affect both the UV and infrared structure of the QCD vacuum. We consider large $28^3 \times 96$ lattices from the MILC collaboration, using a gluonic definition of the topological charge density, founded on a new over ...
