During the years of operation, underground pipelines deteriorate because aging, wear, damage, and destruction. A comprehensive inspection main pipeline revealed various defects on a certain route section. To identify remaining operation life pipeline, number hydraulic tensile strength tests were performed using cyclic loading method. The authors propose to calculate minimum allowable wall thick...

Based on the discovery of surge absorption capability supercapacitors, a transient protector named supercapacitor-assisted absorber (SCASA) was designed and implemented in commercial device. Despite its simplicity, circuit topology consisted coupled inductor wound around specially selected magnetic core. This paper elucidates design aspects SCASA coupled-inductor topologies with special focus a...

A method of tube joining by plastic deformation has efficient, reliable and environmentally friendly features, so that it is widely applied into the fabrication aviation pipeline. Internal rolling potential to join high strength titanium alloy tubes withstanding pressure medium with better sealing performance. Taking TA18 as case material, this presentation combines numerical modelling experime...

Electrospun materials are promising scaffolds due to their light-weight, high surface-area and low-cost fabrication, however, such scaffolds are commonly obtained as ultrathin two-dimensional non-woven meshes, lacking on topographical specificity and surface side-dependent properties. Herein, it is reported the production of three-dimensional fibrous materials with an asymmetrical inner structu...

We present a review of the current status of research into new semiconductor materials for use as particle tracking detectors in very high radiation environments. This work is carried out within the framework of the CERN RD50 collaboration, which is investigating detector technologies suitable for operation at the proposed Super-LHC facility (SLHC). Tracking detectors operating at the SLHC in t...

The main objective of the current review is to cover the overview of silica lipid hybrid microparticles. Lipid-based delivery systems recognized as a potential strategy for improving the oral absorption. Clinical applications of many lipid-based formulations are limited by the lack of clear guidelines of incomplete understanding of absorption mechanism and in vitro, in vivo formulation performa...

Measurements are presented of the electric field at breakdown for perforated flat plates fabricated from carbon-carbon (CC) composite, Poco graphite, pyrolytic graphite (PG), and molybdenum. The perforated flat plates represent electrodes used in ion sources and ion thrusters and measurements are made with and without ion beamlet extraction through the perforations. A ranking of the materials i...

Biofilm-related infections and contamination of biomaterials are major problems in the clinic. These contaminations frequently caused by Staphylococcus aureus a pressing issue for implantable devices, catheters, contact lenses, prostheses, wound dressings. Strategies to decrease biofilm related vital success biomaterials. In this context, hyaluronic acid (HA), naturally derived carbohydrate pol...

This article highlights advancements in polymeric composite/nanocomposites processes and applications for improved radiation shielding high-rate attenuation the spacecraft. Energetic particles, mostly electrons protons, can annihilate or cause space craft hardware failures. The standard practice electronics is utilization of aluminum as safeguard structural enclosure. In space, materials must b...
