An overview of the urbanism style during the Italian era in Benghazi downtown, Libya

open access: yesJournal of Architecture and Urbanism, 2022
Axiomatically, urban fabric is the result of civilizations and ideas overlapping rather than being bound to a single civilization or culture. Benghazi, like many other Arab cities in developing countries, retains relics of its past in the old city core.

Chromatin accessibility: methods, mechanisms, and biological insights

open access: yesNucleus, 2022
Access to DNA is a prerequisite to the execution of essential cellular processes that include transcription, replication, chromosomal segregation, and DNA repair. How the proteins that regulate these processes function in the context of chromatin and its

Effects of recent cooling in the Antarctic Peninsula on snow density and surface mass balance [PDF]

open access: yesPolish Polar Research, 2018
The Antarctic Peninsula region has experienced a recent cooling for about 15 years since the beginning of the 21st century. In Livingston Island, this cooling has been of 0.8°C over the 12-yr period 2004–2016, and of 1.0°C for the summer average ...

Experimental investigations for assessing the influence of fly ash on the flow through porous media in Darcy regime

open access: yesWater Science and Technology, 2021
Hydraulic conductivity plays a vital role in the studies encompassing explorations on flow and porous media. The study investigates the compaction characteristics of a river sand (Beas, Sutlej, and Ghaggar rivers) and fly ash mix in different proportions

Calpain small subunit homodimerization is robust and calcium‐independent

open access: yesFEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

Hardness Safety Testing of Artificial Turf

open access: yesProceedings, 2020
This paper compares four sport surface hardness impact test devices, for use on artificial turf (AT) surfaces to control safety. Sports governing bodies require sport surfaces to be assessed with the “Advanced Artificial Athlete” (AAA) mechanical test ...

Septin 9 PB domains coordinate centrosome positioning and microtubule acetylation to control epithelial polarity

open access: yesFEBS Letters, EarlyView.
Septin 9 polybasic domains couple phosphoinositide‐rich membrane binding to centrosome positioning, Golgi organization, and microtubule acetylation to control epithelial polarity. Their loss disrupts this axis, causing centrosome mispositioning, Golgi fragmentation, reduced microtubule acetylation, and polarity inversion via upregulation of the ...
