Rice husk and activated carbon-silica as potential bioadsorbents for wastewater purification [PDF]

open access: yesCaspian Journal of Environmental Sciences, 2021
Heavy metals are generally found in industrial wastewaters, affecting human health and living organisms. This study was therefore aimed to use bioadsorbents rice husk and activated carbon-silica to efficiently remove the heavy metals including lead (Pb ...

Survey of electron density changes in the daytime ionosphere over the Arecibo observatory due to lightning and solar flares

open access: yesScientific Reports, 2021
Optical observations of transient luminous events and remote-sensing of the lower ionosphere with low-frequency radio waves have demonstrated that thunderstorms and lightning can have substantial impacts in the nighttime ionospheric D region. However, it

Brd2/4 and Myc regulate alternative cell lineage programmes during early osteoclast differentiation in vitro

open access: yesiScience, 2021
Summary: Osteoclast (OC) development in response to nuclear factor kappa-Β ligand (RANKL) is critical for bone homeostasis in health and in disease. The early and direct chromatin regulatory changes imparted by the BET chromatin readers Brd2-4 and OC ...

The innate sensor ZBP1-IRF3 axis regulates cell proliferation in multiple myeloma

open access: yesHaematologica, 2021
Multiple myeloma is a malignancy of plasma cells initiated and driven by primary and secondary genetic events. However, myeloma plasma cell survival and proliferation might be sustained by non-genetic drivers.

Chromatin-based, in cis and in trans regulatory rewiring underpins distinct oncogenic transcriptomes in multiple myeloma

open access: yesNature Communications, 2021
Despite extensive genetic heterogeneity, nearly half of all multiple myeloma (MM) cases are driven by cyclin D2 (CCND2) over-expression. Here the authors dissect the chromatin landscape of MM to provide insights into the transcriptional regulatory ...

Synthesis, characterization, and performance of chitosan/nylon 6/polyurethane blend for the removal of chromium (VI) and lead (II) ions from aqueous solutions for enhanced kinetic adsorption studies

open access: yesJournal of Water Reuse and Desalination, 2023
Adsorption is vital for the elimination of Cr6+ and Pb2+ ions in the contaminated solution medium. A ternary blend made up of chitosan, nylon 6 and polyurethane foam (CS/Ny 6/PUF) blend in the ratio of 2:1:1 has been investigated.

Polarity Asymmetries in Rocket‐Triggered Lightning

open access: yesGeophysical Research Letters, 2023
The dissonant development of positive and negative lightning leaders is a central question in atmospheric electricity. It is also the likely root cause of other reported asymmetries between positive and negative lightning flashes, including the ones ...

Phosphorus behavior under long-term fertilization in the intensive rice cultivation system

open access: yesPlant, Soil and Environment, 2023
Advocating proper phosphorus (P) fertilisation is necessary to save this limited natural resource and to save the investment in rice cultivation. This study aimed to evaluate changes in phosphorus availability, total phosphorus in soil, phosphorus ...

Nanoparticles: Characteristics, Mechanisms and Modulation of Biotoxicity

open access: yesKONA Powder and Particle Journal, 2014
Particulates of 1 to 100 nanometers size are being increasingly used for a variety of clinical and commercial purposes due to their large surface-to-volume ratio and unique physico-chemical, mechanical and electronic

Cavitating Langmuir Turbulence in the Terrestrial Aurora [PDF]

open access: yes, 2012
Langmuir cavitons have been artificially produced in the earth's ionosphere, but evidence of naturally-occurring cavitation has been elusive. By measuring and modeling the spectra of electrostatic plasma modes, we show that natural cavitating, or strong,
