Revised Rebound Hammer and Pull-Out Test Strength Curves for Fiber-Reinforced Concrete

open access: yesAdvances in Civil Engineering, 2020
Rebound hammer tests and postinstalled pull-out tests are commonly used for evaluating the compressive strength of ordinary concrete, and the strength of concrete is estimated by strength curves.

MODELING PULL-OUT TEST OF DENTAL IMPLANTS [PDF]

open access: yesBiomedical Engineering: Applications, Basis and Communications, 2003
The objective of this paper is to investigate bone-implant interface failure using analytical techniques of fracture mechanics. The implant usually is anchored to the surrounding bone by growth of bony tissue into the surface of the implant. A mechanical interlock is formed between the implant and the bone. Plane strain conditions are imposed.

Failure analysis and the effect of material properties on the screw pull-out behaviour of polymer composite sleeper materials

open access: yes, 2021
The low pull-out resistance and the limited understanding of how the sleeper materials affect the screw pull-out behaviour is one of the key reasons for the lack of confidence in the wide adoption of available composite railway sleepers.

The pull-out test on knit bamboo reinforcement embedded into concrete beam

open access: yesMATEC Web of Conferences, 2019
The pull-out test is generally conducted to obtain accurately the carrying capacity of the flexural strength of the knit bamboo reinforced concrete beam, which is more determined by the bonding strength than the tensile strength of reinforcement in ...

Clinical and Biological Features of Response in Resistant Neuroblastoma to 131I‐Metaiodobenzylguanidine Radiotherapy in the Anti‐GD2 Immunotherapy Era

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background 131I‐metaiodobenzylguanidine (131I‐MIBG) radiotherapy is a key treatment for relapsed and refractory (R/R) neuroblastoma (NB). Patients with R/R disease treated in the modern era are increasingly exposed to anti‐GD2 immunotherapy, which exerts selective pressure and may modify both tumor cell state and microenvironment.

Investigation of interfacial strength parameters in polymer matrix composites: Compatibility and reproducibility

open access: yesAdvanced Industrial and Engineering Polymer Research, 2018
Effects of various geometrical and physical factors, as well as the method of data reduction (analysis of experimental force–displacement curves) on the values of local interfacial strength parameters (local IFSS, τd, and critical energy release rate ...

Heterogeneity in the Global Practice of Central Nervous System Staging in Pediatric Acute Lymphoblastic Leukemia

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Central nervous system (CNS) involvement in childhood acute lymphoblastic leukemia (ALL) is assessed by cell counting and cytomorphology from cerebrospinal fluid (CSF) and is used for treatment stratification worldwide. The ratio of “CNS2” patients in clinical trials ranges from 3% to 40%, with unclear prognostic significance ...

The Behavior of a Thread-Bar Grouted Anchor in Soils from Local Strain Monitoring

open access: yesApplied Sciences, 2020
International standards discourage the use of grouted anchors with a fixed length exceeding 10 m. However, grouted anchors with a fixed length between 10 and 20 m are frequently used in Italy to transfer high loads to ground with poor geotechnical ...
