YlmG1 is localized exclusively to the chloroplast envelope membrane and is involved in preprotein translocation in Arabidopsis thaliana

open access: yesFEBS Open Bio, EarlyView.
Cytosolically synthesized chloroplast preproteins are translocated across the outer and inner envelope membranes through translocons called TOC and TIC, respectively. In green algae and plants, the TIC core is composed of essential membrane proteins, Tic12, Tic20, and Tic214.

Implementation of High Air Voids Asphalt Mixtures on Trial Section—Performance Evaluation Case Study

open access: yesApplied Sciences
Asphalt mixtures designed with an elevated air void content are intended to lower traffic noise as well as to improve traffic safety and quality by improving rainwater evacuation through the layer of the surface mixture, not just on top of it.

Spalling of concrete – influence of porosity and specimen size and its critical factors regarding safety

open access: yesMATEC Web of Conferences, 2013
The influence of porosity and of the specimen geometry and its stiffness on the behaviour of spalling in an event of fire is investigated. Fire resistance is heavily depending on the w/c and air void content values.

Hydraulic conductivity of composite soils [PDF]

open access: yes, 2017
Many natural soils (e.g. glacial tills, residual soils, and alluvial soils) and artificial soils (e.g. engineered fill, environmental barriers) are formed of a range of particle sizes and types.

The skills required for transition to university and study in biological sciences: A student perspective

open access: yesFEBS Open Bio, EarlyView.
Bioscience students were asked for their opinions on the value and teaching of skills. 204 responded that teamwork, time management and study skills are necessary to reach University, that scientific writing, research, laboratory and presentation skills are taught effectively during their studies, while other skills are gained inherently through study ...

Determination of maximum and minimum void ratios of sands and their influence factors

open access: yesYantu gongcheng xuebao, 2018
The mechanical behaviors of sand are heavily dependent on its relative density: the dense sand exhibits softening strength; on the contrary, the loose one displays hardening strength.

Molecular dynamics simulations of positively selected codons in FcγRI reveal novel biochemical binding properties

open access: yesFEBS Open Bio, EarlyView.
Evolutionary analysis across 32 placental mammals identified positive selection at residues H148 and W149 in the immune receptor FcγR1. Ancestral reconstruction combined with molecular dynamics simulations reveals how these mutations may influence receptor structure and dynamics, providing insight into the evolution of antibody recognition and immune ...

Dielectric Response of Asphalt Mixtures and Relationship to Air Voids and Stiffness

open access: yesConstruction Materials
Asphalt mix air void content is a dominant parameter for asphalt mix design. The air void content of the mix affects the mechanical property of stiffness, while both characterize compacted asphalt mix materials.

The undrained shear strength characteristics of silty sand: an experimental study of the effect of fines

open access: yesGeologia Croatica, 2011
This laboratory investigation has been conducted to elucidate how the fines fraction affects the undrained residual shear strength and liquefaction potential of sand-silt mixtures (Algeria).

Structural Studies on Semiconducting Hydrogenated Amorphous Silicon Oxide Films

open access: yes, 2002
In hydrogenated amorphous silicon oxide (a-SiO:H) films, incorporation of oxygen enhances optical gap due to a large number of St-O-Si bond formation, which lies deep into valence band states.
