Ultrasonic scanning system for in-place inspection of brazed tube joints [PDF]

, 1973
A miniaturized ultrasonic scanning system for nondestructive in-place, non-immersion testing of brazed joints in stainless-steel tubing is described. The system is capable of scanning brazed tube joints, with limited clearance access, in 1/4 through 5/8 ...

Pharmacokinetics, safety, and efficacy of a single co-administered dose of diethylcarbamazine, albendazole and ivermectin in adults with and without Wuchereria bancrofti infection in Cote d\u27Ivoire [PDF]

, 2019
BackgroundA single co-administered dose of ivermectin (IVM) plus diethylcarbamazine (DEC) plus albendazole (ALB), or triple-drug therapy, was recently found to be more effective for clearing microfilariae (Mf) than standard DEC plus ALB currently used ...

Effects of the Fluid Replacement Method During Online Hemodiafiltration on the Solute Removal Performance and Biocompatibility Using the Asymmetric Cellulose Triacetate Membrane

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Pre‐dilution online hemodiafiltration (Pre‐HDF) is predominantly used in Japan, whereas post‐dilution online HDF (Post‐HDF) is more common in Europe. An asymmetric cellulose triacetate (ATA) membrane may improve biocompatibility.

Spatial revolute joints with clearance and friction for dynamic analysis of multibody mechanical systems [PDF]

, 2016
A study on the effects of dry spatial revolute joints with clearance and friction is delivered through this work. Both radial and axial clearances are taken into consideration which makes the model more realistic for three-dimensional motion.

A methionine‐lined active site governs carbocation stabilization and product specificity in a bacterial terpene synthase

FEBS Letters, EarlyView.
This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

Wear prediction for dry revolute joint with clearance in multibody system by integrating dynamics model and wear model

Latin American Journal of Solids and Structures
This work presents an investigation on wear prediction of multibody system including dry revolute clearance joint using a computational methodology. A procedure to analyze multibody system in which wear is present at revolute joints is presented.

Effect of joint clearance on fatigue strength of brazed joint.

QUARTERLY JOURNAL OF THE JAPAN WELDING SOCIETY, 1989
The effects of joint clearance on fatigue crack initiation life and crack growth rate of brazed joint were investigated.Tes tspecimens used were butt joint of carbon stcel and stainless steel brazed with pure copper with/without an artificial defect in joint.It was inferred from the fatigue test results that fatigue life of joint depend not on crack ...

Nonlinear Characteristic of Spherical Joints with Clearance

Journal of Aerospace Technology and Management, 2015
Joints in deployable structures can degrade the stiffness and the stability of spacecraft. In this study, the nonlinear stiffness of spherical joints is investigated. The traditional contact model of spherical joints based on non-conforming contact assumption is presented.

Transcriptional network analysis of PTEN‐protein‐deficient prostate tumors reveals robust stromal reprogramming and signs of senescent paracrine communication

Molecular Oncology, EarlyView.
Combining PTEN protein assessment and transcriptomic profiling of prostate tumors, we uncovered a network enriched in senescence and extracellular matrix (ECM) programs associated with PTEN loss and conserved in a mouse model. We show that PTEN‐deficient cells trigger paracrine remodeling of the surrounding stroma and this information could help ...
