Liquefaction Potential of Unsaturated Nevada Sand Considering Different Intial Conditions
… the same, the cycles needed to make the specimen liquefy increased with the relative density. For the same other initial conditions, the number of cycles required to make the saturated specimen liquefy increased with an increase in the effective confining pressure.</p> <p>For unsaturated Nevada …

Comparative Assessment of the Societal Cost of PtL and LH₂ as Aviation Fuels
… is no consensus whether it is preferable to liquefy hydrogen and use it directly as a fuel (LH₂) or to combine it with CO₂ captured from point sources or the atmosphere to create a synthetic hydrocarbon fuel (PtL). Much of this disagreement is a result of the wide range of uncertainty that …

Optimal Location of Biomethane Gas Manufacturing Plants and Allocation of Feedstock and Liquified Carbon Product
… transported from the hubs, the condensers that liquefy the BMG from the reactors, and the delivery points that act as end distributors and accept the liquefied BMG from condensers. The logistics of a BMG production system can be divided into four stages: farm-to-hub (F2H) stage, hub-to-reactor …

Cyclic behavior of cohesionless granular media using the compact state concept
… denser than the critical void ratio could also liquefy as the tendency to contract exists even in these deposits. Dilatation manifests itself only if the deposit is subjected to large amplitude cyclic loading. Such high stress loading cycles are not likely to occur very often in nature. The …

Capture and recovery of organic gases with electrothermal swing adsorption and post-desorption treatment
… and compression energy required to capture and liquefy the gases ranged from 1,200 to 52,000 kJ/mol liquefied depending on the relative pressure of the inlet adsorbate. This energy consumption is 0.87 – 138 times that to recover vapors with boiling points ranging from 56.5 - 101°C using the …

Wave induced response of sea floor deposits : a simple model for sands and nonlinear analysis by FEM
… of permeability even a loose sand mass need not liquefy. This is in direct contrast to the commonly held view that the liquefaction potential is a function of density only. Two example cases are studied in detail. The first example examines the seabed response to the wave train at a pipeline site …

Functional ionic liquids for use in pharmaceutical applications
… and transportation. Thus, a new method to liquefy pharmaceuticals, thereby reducing problems associated with the solid-state, is needed. A potential solution is the use of ionic liquids (IL), defined as salts that melt below 100 °C. Since ILs are salts it is possible to combine a …

Bacteria isolated from coriander and other umbelliferous herbs
… tobacco hypersensitivity, ability to liquefy gelatin, ability to ice nucleate, ability to degrade pectate, poly-β-hydroxybutyrate accumulation, and ability to utilize more than 100 substrates as sole sources of carbon and energy. The results of these tests were analyzed in a numerical …

Sustainable design and durability of domestic micro combined heat and power scroll expander systems.
… It was found that sufficiently high pressure can liquefy instantaneously part of the refrigerant close to the bottom boundary, creating conditions for the generation of cavitation bubbles within the liquefied refrigerant. This finding resolves the puzzle of how the refrigerant which enters the …

An investigation into the use of REITs to finance affordable housing in Mainland China
… in China. Municipal governments lack a way to liquefy these rental properties and attract private investment. On one hand, municipal governments hold a lot of rental properties worth billions of money; On the other hand, they still lack funding sources to finance new affordable rental housing. …

Processi di biorefining per l'estrazione di secondary chemical building blocks da sottoprotti dell'agro-industria
… wheat bran and the optimized process allowed to liquefy up to the 60 % of the treated matter. The enzymatic treatment was also able to solubilise up to the 30 % of the alkali extractable ferulic acid. An extraction process of the phenolic fraction of the hydrolyzed wheat bran based on an …

Reconciling materialism and anti-consumption: A grounded approach to the co-existence of solid-liquid consumption in fashion rentals
… goals in solid consumption led consumers to liquefy their consumption by subscribing to fashion rentals. Fashion rentals enable consumers to adopt minimalistic practices where they prioritise higher-order goals that are embedded in both materialistic and anti-consumption values, thereby …

The synthesis and development of novel, easily processable poly (n-isopropylacrylamide)-based hyrdogels.
… forms a cross-linked hydrogel that does not re-liquefy upon re-heating, but instead, possesses all of the highly utilisable stimuli-responsive properties typical of PNIPAM-based nanocomposite hydrogels synthesised in situ. This novel methodology simultaneously addresses issues including …

Vývoj nové technologie ztekucení a stabilizace zemin
V dnešní době je snahou sledovat vlivy související s dopadem na naši ekologii a zabývat se odpadovým hospodářstvím. Výkopové zeminy jsou brány jako odpad, a proto často končí na skládkách deponiích, či mezideponiích. Snahou je tyto zeminy zužitkovat. Přidáním vhodných stabilizačních přísad se dají …
