Dynamic induced softening in frictional granular material investigated by DEM simulation [PDF]

, 2017
A granular system composed of frictional glass beads is simulated using the Discrete Element Method. The inter-grain forces are based on the Hertz contact law in the normal direction with frictional tangential force.

Capacitive Spring Softening in Single-Walled Carbon Nanotube Nanoelectromechanical Resonators

, 2010
We report the capacitive spring softening effect observed in single-walled carbon nanotube (SWNT) nanoelectromechanical (NEM) resonators. The nanotube resonators adopt dual-gate configuration with both bottom-gate and side-gate capable of tuning the ...

Development of the Metal Rheology Model of High-temperature Deformation for Modeling by Finite Element Method [PDF]

, 2019
It is shown that when modeling the processes of forging and stamping, it is necessary to take into account not only the hardening of the material, but also softening, which occurs during hot processing.

The Fate (Outcome) of Clinically Apparent Single Lesion and Oligofocal Nephroblastomatosis Treated According to SIOP/GPOH Protocols for Wilms Tumor

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background The management of clinically apparent single lesions or oligofocal nephroblastomatosis, a facultative precursor of nephroblastoma, remains debated. Methods We retrospectively analyzed 37 patients with clinically apparent single or oligofocal nephroblastomatosis (two to three lesions per kidney) among 2347 patients registered between

ON A NEW TECHNOLOGY OF PREPARATION OF HOT DRINKING WATER

Известия высших учебных заведений и энергетических объединенний СНГ: Энергетика, 2017
The present article contains information concerning the new Cl-anionization technology in the preparation of hot drinking water. In contrast with water softening, that replaces all the hardness salts by sodium cations in the cation exchanger, this new ...

Feasibility and Safety of High‐Dose Proton Re‐Irradiation in Recurrent Pediatric Central Nervous System Tumors: A Single‐Institution Retrospective Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Purpose Pediatric central nervous system (CNS) tumors often recur despite multimodality therapy. Although re‐irradiation (re‐RT) has historically been limited by concerns for severe late toxicities, modern techniques have renewed interest in this approach. Proton therapy provides dosimetric advantages that may enable curative re‐treatment with

Softening and Yielding of Soft Glassy Materials

, 2017
Solids deform and fluids flow, but soft glassy materials, such as emulsions, foams, suspensions, and pastes, exhibit an intricate mix of solid and liquid-like behavior. While much progress has been made to understand their elastic (small strain) and flow

IMPDH inhibition enhances cytarabine efficacy in SAMHD1‐expressing leukaemia cells via guanine nucleotide depletion

Molecular Oncology, EarlyView.
Cytarabine is a key therapy for acute myeloid leukaemia (AML), but its efficacy is limited by the dNTPase SAMHD1, which hydrolyses its active metabolite. Screening nucleotide biosynthesis inhibitors revealed that IMPDH inhibitors selectively sensitise SAMHD1‐proficient AML cells to cytarabine.

Influence of ethanol concentration on softening tests for cross-link density evaluation of dental composites

Materials Research, 2007
This study investigated the influence of ethanol concentration on softening tests for cross-link density evaluation (microhardness) of dental composites. Specimens of Filtek Z100 (3M ESPE) were light-activated by standard or pulse-delay methods.

Mechanism of Softening Effect of Fabric Softener

Journal of Materials Science Research, 2013
The mechanism of softening effect for fabric softeners has been explained as lowering of friction between the fibers. This explanation, however, has not been verified. The trend date of B-value of KES-FB2 and the result of perfect drying cotton threads indicate that the increase of hardness of cotton threads after the process of wetting by water and ...
