Cyclic resistance of a decomposed granite [PDF]

E3S Web of Conferences, 2019
An important issue surrounding the identification of liquefaction susceptibility using laboratory testing is how well the soil sample being tested represents the soil in the field.

Insulin Resistance Develops Due to an Imbalance in the Synthesis of Cyclic AMP and the Natural Cyclic AMP Antagonist Prostaglandylinositol Cyclic Phosphate (Cyclic PIP)

Stresses, 2023
The reasons initiating insulin resistance are not identified. Various metabolic derailments have been characterized. These are the outcome and not the initiation of insulin resistance.

Resistance to Antimalarial Monotherapy Is Cyclic [PDF]

Journal of Clinical Medicine, 2022
Malaria is a prevalent parasitic disease that is estimated to kill between one and two million people—mostly children—every year. Here, we query PubMed for malaria drug resistance and plot the yearly citations of 14 common antimalarials. Remarkably, most antimalarial drugs display cyclic resistance patterns, rising and falling over four decades.

Experimental Study on Liquefaction Characteristics of Coral Gravelly Soils with Different Particle Size Distributions

Journal of Marine Science and Engineering, 2023
Many laboratory studies have shown that particle size distribution (PSD) affects the liquefaction susceptibility of granular materials. However, few studies have focused on the impact of PSD on coral particles.

Cyclic resistance of fly ash influenced by anisotropic stress condition, sand contents, and gravel content

Soils and Foundations, 2022
A series of cyclic triaxial tests were performed to study the effect of anisotropic stress, sand content (in a fly ash-sand mixture), and addition of gravel on the cyclic resistance of fly ash.

Effect of NaOCl on cyclic fatigue resistance

Bioinformation, 2023
The impact of 5.25 percent NaOCL on the resistance offered by TruNatomy, Hero Gold and Protaper Gold against cyclic fracture as against the treatment of NiTi rotary files with distilled water is of interest to dentists. Inside the stainless steel blocks, man-made canals were created for the purpose of testing the cyclic fatigue.

Undrained Cyclic Response and Resistance of Saturated Calcareous Sand considering Initial Static Shear Effect

Geofluids, 2021
Sand elements in the natural or manmade field have often undergone initial static shear stresses before suffering cyclic loading. To explore the effect of static shear stress, a series of undrained cyclic triaxial tests were performed on dense and loose ...
