Is the HCV-HIV co-infection prevalence amongst injecting drug users a marker for the level of sexual and injection related HIV transmission?

open access: yes, 2013
BACKGROUND: Amongst injecting drug users (IDUs), HIV is transmitted sexually and parenterally, but HCV is transmitted primarily parenterally. We assess and model the antibody prevalence of HCV amongst HIV-infected IDUs (denoted as HCV-HIV co-infection ...

Recurrent intussusception associated with pneumatosis cystoides coli: A pediatric case report

open access: yesJPGN Reports, Volume 7, Issue 1, Page 51-54, February 2026.
Abstract Pneumatosis cystoides coli (PCC) describes gas‐filled cysts within the wall of the gastrointestinal tract and is uncommon in children. We report a 7‐year‐old female with a history of recurrent ileocolic intussusception secondary to PCC. Her initial episodes of intussusception resolved spontaneously or with air enema, but no lead point was ...

Microstructural Characteristics and Mechanical Properties of Water Cooling Bobbin-Tool Friction Stir Welded 6063-T6 Aluminum Alloy

open access: yesMATEC Web of Conferences, 2018
In this study, a novel welding method called water cooling bobbin-tool friction stir welding (WBT-FSW) was developed. 4 mm-thick 6063-T6 aluminum alloy sheets were successfully jointed by WBT-FSW.

Modular multilevel converter losses model for HVdc applications [PDF]

open access: yes, 2017
Multi-terminal high voltage dc (HVdc) grids can eventually became a feasible solution to transport energy to remote and/ or distant areas and its exploitation depend, among other things, on the performance of the converter terminals.

Switched Capacitor Voltage Converter [PDF]

open access: yes, 2019
This project supports IoT development by reducing the power con- sumption and physical footprint of voltage converters. Our switched- capacitor IC design steps down an input of 1:0 - 1:4 V to 0:6 V for a decade of load current from 5 ...

Parametric finite-element studies on the effect of tool shape in friction stir welding [PDF]

open access: yes, 2010
The success of the Friction Stir Welding (FSW) process, and the weld quality produced, depends significantly on the design of the welding tool. In this paper the effect of variation in various tool geometry parameters on FSW process outcomes, during the ...
