Characterization and determination of the S/G ratio via Py-GC/MS of agricultural and industrial residues
Oksanka [162]

Characterization and determination of the S/G ratio via Py-GC/MS of agricultural and industrial residues.

<h3>What is the abstract?</h3>

To investigate the potential lignin values, agricultural residues (apple tree pruning, olive tree pruning, and almond shell) and industrial residues (kraft black liquor) were employed as source materials for lignin extraction via various fractionation procedures (kraft, organosolv, acetosolv and acetosolv and formosolv processes). Py-GC/MS, FTIR, and GPC were used to characterise the separated lignins. The fractionation method had a significant impact on the average molecular weight (Mw) assessed by GPC. The severe circumstances of the acetosolv and acetosolv-formosolv procedures favoured repolymerization, resulting in high Mw lignins. Because of the longer retention durations, the EKL had a smaller Mw. Except for almond shell lignin, which has the highest relative abundance of G-type phenols, all lignins have higher relative abundances of S-type phenols.

_______________ refers to the tendency of a foundation material (such as soil) that is water-logged to lose its internal cohesio
dybincka [34]

Answer:

<u>Liquefaction</u> refers to the tendency of a foundation material (such as soil) that is water-logged to lose its internal cohesion and mechanically fail to provide support during earthquake shaking.

Explanation:

Liquefaction occurs when an unbound material (usually sand), which is saturated in water, loses its resistance to shear due to intense and rapid vibration (earthquake), which breaks its granular structure by reducing its inter-granular pressure and flow like a liquid because of an increase in pressure.

Liquefaction usually manifests itself in loose, saturated and non-cohesive soils, formed by young deposits of sands and sediments of similar particle sizes. If the soil is dense there will be less chances of liquefaction. Older deposits, in general, are more dense and cohesive. At higher density, more interstitial pressure is needed for liquefaction to occur.

Monica [59]
Most animals in Animalia have backbones, but not all.
The correct answer would be C, because all organisms in Animalia are heterotrophs which means that they depend on other organisms (like animals and plants) for food.
