The critical element for sustainable growth in the construction industry is development of alternative cements. A new technological process called geopolymerization provides an innovative solution, and presence aluminum silicon oxides fly ash has encouraged its use as a source material. Many previous investigations have involved curing binder heated environment. To reduce energy consumption during synthesis geopolymers, present study investigated properties ambient cured geopolymer mortar at...
Cross-language studies, as reflected by the scalp-recorded frequency-following response (FFR) to voice pitch, have shown influence of dominant linguistic environments on encoding pitch at brainstem level in normal-hearing adults. Research questions that remained unanswered included characteristics FFR neonates during their immediate postnatal period and relative contributions biological capacities present birth versus listener's experience. The purpose this study was investigate first few...
Abstract Healthy aging leads to complex changes in the functional network of speech processing a noisy environment. The dual‐route neural architecture has been applied study processing. Although evidence suggests that senescent increases activity brain regions across dorsal and ventral stream offset reduced periphery, regulatory mechanism networks underlying such compensation remains largely unknown. Here, by utilizing near‐infrared spectroscopy (fNIRS), we investigated compensatory...
Concrete recycling provides sustainability benefits in conservation of virgin aggregate resources, landfill reduction, energy savings, and reduced greenhouse gases emission. Effective new uses recycled concrete (RCA) cement industry have attracted a lot researchers’ attention from the perspective environmental preservation sustainable utilization resources. While local RCA could be successfully used portland concrete, most RCA, particularly fine (FRCA) are currently only low-profile...
Abstract Our ability to localize low‐frequency sounds relies on interaural time differences (ITD), a sensitivity that is fundamental our pinpoint sound sources in azimuth and segregate competing across wide range of situations. However, the neural representation ITD has not been well characterized. This study aimed elucidate distinctions evoked cortical potentials global functional connectivity during unattended processing localization horizontal plane, by recording analyzing auditory...
Neural plasticity of pitch processing mechanisms at the human brainstem, as reflected by scalp-recorded frequency-following response (FFR) to voice pitch, has been reported for normal-hearing adults. Characteristics and maturation such a during first year life have remained unclear. The purpose this study was examine characteristics FFR in infants make direct comparison with adults using same stimulus recording parameters. 9 were recruited. A Chinese monosyllable that mimics English vowel...
To successfully process concrete, it is necessary to predict and control its flow behavior. However, the workability of concrete not completely measured or specified by current standard tests. Furthermore, only with a clear picture cement hydration setting that full prediction performance can be generalized. In order investigate rheological properties blended pastes, rotational viscometer (RV) was used determine characteristics ordinary pastes provide assurance pumped handled. Additionally,...
The effects of aggregate characteristics on the flow ability mortar mixtures were investigated. Two types, five single-sized and three graded fine considered. Uncompacted voids aggregates measured. Flow properties 166 batches made with different aggregates, sand-to-cement ratios (s/c) water-to-cement (w/c), evaluated using modified ASTM C109 table test method. results indicated that in addition to w/c, content, uncompacted voids, size all significantly affect ability. Generally, having...
Fiber reinforced aerated lightweight concrete (FALC) was developed to reduce concrete's density and improve its fire resistance, thermal conductivity, energy absorption. Compression tests were performed determine basic properties of FALC. The primary independent variables the types volume fraction fibers, amount air in concrete. Polypropylene carbon fibers investigated at 0, 1, 2, 3, 4% ratios. aggregate used made expanded clay. A self-compaction agent water-cement ratio keep good...
Objective. Voice pitch carries important cues for speech perception in humans. Recent studies have shown the feasibility of recording frequency-following response (FFR) to voice normal-hearing listeners. The presence such a response, however, has been dependent on subjective interpretation experimenters. purpose this study was develop and test an automated procedure including control-experimental protocol response-threshold criteria suitable extracting FFRs pitch, compare results human...
Self-consolidating concrete (SCC) is an innovative type of that requires little to no mechanical vibration, and can be consolidated into formwork under its own weight. While the precast industry has fully adopted SCC because tremendous benefits, overall use in market, particularly ready-mixed production, still very limited. One main obstacles prevents wide high cost environmental impact associated with powder (cement, cementitious materials, filler) content. A new concept eco-efficient...
