The thermally assisted mechanical dewatering process, investigated in this paper, couples in one stage mechanical dewatering at low pressure (Papplied < 1125 kPa) with a moderated heating (T < 80°C). Former studies emphasized that the separation enhancement depends on the product. To identify the mechanisms involved, a 1D filtration/compression cell is instrumented with pore liquid sensors dist...

geotechnical investigations of waste fills are rarely undertaken, and consequently the geotechnical community has little knowledge of their engineering properties. in this study, a geotechnical testing program was conducted to evaluate the engineering properties of old municipal solid waste sampled in whamyung msw landfill site, busan, korea. the conducted tests included water content, specific...

Abstract Ultrasonic consolidation (USC) of thermoplastic composites is a highly attractive and promising method to manufacture high-performance composites. This work focuses on USC dry carbon fiber (CF) fabrics with high-temperature polyphenylene sulfide (PPS) films. Experimental trials assess feasibility the process are time-consuming. Consequently, predictive thermal model would facilitate pa...

Vertical drains and stone columns which have been used in infrastructure construction for highways, ports, coastal regions, etc., provide significant benefits for improving soil characteristics such as reducing the drainage length and accelerating the consolidation process. So the investigation of the radial consolidation is inevitable. Soils may be subjected to cyclic loading such as silos, ta...

growing evidence suggests that serotonin plays an important role in learning and memory and all its receptors might be implicated in this process. the present study aimed at investigating and comparing the possible involvement of 5-ht 3 and 5-ht 4 receptor (r) agonists/antagonists upon consolidation of inhibitory avoidance memory in the pre-limbic (pl) area. bilateral intra-pl microinjections o...

For achieving high quality of in situ consolidation thermoplastic Automated Fiber Placement, an approach is presented this research work. The deals with the combination material pre-heating and sub-ultrasonic vibration treatment. Therefore, work investigates influence frequency dependent pressure on quality. A simplified experimental setup was developed that uses resistance electrical heating i...

Thermal stability and the kinetics of the grain growth of nano-crystalline Mg-6Al-1Zn-1Si alloy prepared via mechanical alloying (MA) were investigated. It started with elemental powders, using a variety of analytical techniques including differential scanning calorimetry (DSC), X-ray diffraction method (XRD), and scanning electron microscopy (SEM) coupled with energy dispersive spectrometry (E...

Fiber reinforced composites are increasingly used in high value applications. A novel technology (NanoWeld®) enhancing the structural integrity of interlayer has demonstrated promising results; however, manufacturing issues related to scalability need be overcome. The developed relies on consolidating thermoplastic nanofiber nonwoven veils onto technical dry fabrics through roll-to-roll ultraso...

Thermally-assisted compaction of granular materials is of keen interest in many engineering applications. A proper estimation of the material behavior of compacted granular materials is contingent upon the knowledge of microstructure formation, which is highly dependent on the bulk material properties and processing conditions, during the deformation stage. Originating from the pair interaction...
