Abstract The adsorption dynamics of a layered bed packed with activated carbon and zeolite 5A were studied experimentally theoretically through breakthrough experiments two‐bed pressure swing (PSA) processes by using coke oven gas (56.4 vol. % H 2 ; 26.6 CH 4 8.4 CO; 5.5 N 3.1 CO ). results curves showed an intermediate behavior those zeolite‐5A bed, because each concentration front propagates its own wavefront velocity in layer different equilibrium. Since fast dispersed mass‐transfer zone...
A study on a two-bed six-step pressure swing adsorption (PSA) process using zeolite 5A was performed experimentally and theoretically for bulk separation of H2/CO H2/CH4 systems (70/30 vol %) as major components in coke oven gas. When the is cycled between 1 11 atm at ambient temperatures, 70% H2 feed could be concentrated to 99.99% product with recovery 75.87% mixture 80.38% mixture. The effects pressure, P/F ratio, adsorption/purge step time, equalization time were investigated...
Abstract Effects of carbon‐to‐zeolite ratio on a layered bed H 2 PSA using activated carbon and zeolite 5A were studied experimentally theoretically. Coke oven gas (56.4 vol. % , 26.6 CH 4 8.4 CO, 5.5 N 3.1 CO ) was used as feed for the seven‐step two‐bed process incorporating backfill step. In these experiments, effects three operating variables such adsorption pressure, rate purge performance investigated. The gave better purity than single‐adsorbent at same condition, except low rate....
Abstract: Introduction: Previous research on teacher support for motivation processes and positive outcomes of students in physical education has yet to explore relatedness supportive instructions. Aim: This study investigates the influence after-school activity through mediating roles intrinsic self-efficacy among university participating physical-education classes. Methods: 297 (165 males, 132 females; freshman senior years; Mage = 20.8; SD 4.2) completed four questionnaires at end...
Web page segmentation into logical blocks is an important preprocessing step for recognizing informative content in a that leads to efficient information extraction and convenient display on the devices with small-sized screens. Previous methods are not flexible dynamic environment because they largely relied heuristic rules generated by exploiting structural tags visual inherent page. To resolve this problem, paper proposes new method of repetitive tag patterns called key DOM tree structure...
This paper proposes a more scalable comparison-shopping agent named MORPHEUS. MORPHEUS presents simple but robust inductive learning algorithm that automatically constructs wappers.
Mobile content adaptation is a technology of effectively representing the contents originally built for desktop PC on wireless mobile devices. Previous approaches Web are mostly device-dependent. Also, transformation to suit smaller device done manually. As result, user has difficulty in selecting relevant information from heavy volume since context related not provided. To resolve these problems, this paper proposes an enhanced method In our system, process consists 4 stages including block...
Abstract: Background: Previous research has not investigated why and how adolescents decide to continuously engage in Taekwondo activity, which, based on self-determination theory, positive effects diverse (physical, psychological, social) aspects. This study examines the structural relationship between three psychological needs (autonomy, competence, relatedness), intrinsic motivation, intentions for activity continuity among high-school students participating training programs. Methods:...
Abstract Epitachophoresis is a novel next generation extraction system capable of isolating DNA and RNA simultaneously from clinically relevant samples. Here we build on the versatility by extracting diverse nucleic acids ranging in lengths (20 nt–290 Kbp). The quality extracted miRNA, mRNA gDNA was assessed downstream Next-Generation Sequencing.
To increase the sense of immersion 360 virtual reality (VR) images, this paper proposes and implements foveated rendering technology through precise region-of-interest (ROI) detection using eye-tracking-based head-mounted display. It uses HEVC tiled video-based image-decoding -rendering method, which results show high speeds high-quality textures.
