The bond between steel bars and concrete is a fundamental aspect of reinforced concrete, ensuring the efficient transfer forces two materials guaranteeing their compatibility composite action. conventional equation for calculating stress does not account slip effects. However, significant can lead to considerable errors, which are disadvantageous when analyzing performance using finite element methods. To address this issue, study proposed modified calculation model, whose reliability was...
To investigate the micro-mechanism of erosion hydrated calcium silicate (C-S-H gel) in a sulfate environment, solid-liquid molecular dynamics model C-S-H gel/sodium was developed. This employs methods to simulate transport processes between gel and corrosive ions at concentrations 5%, 8%, 10% sodium (Na
Studies related to air pollutants and spontaneous abortion in urban northwestern China are scarce, the main exposure windows of acting on pregnant women unclear. Case-control study. Data were collected from Tongchuan City 2018 2019. A total 289 cases 1156 full-term labor included analyzed using a case–control Logistic regression models developed explore relationship between after Chi square analysis Air pollutant description. O3 (odds ratio [OR] = 1.028) is risk factor for throughout...
Abstract Objective To collect maternal maternity information on preterm births in two tertiary hospitals the urban area of Baota District, Yan'an City, from January 2018 to December 2020, explore long-term and short-term effects air pollutants (PM 2.5 , PM 10 SO 2 NO CO O 3 ) births, changes blood cell counts due pollutants. Methods Daily average mass concentration data six City 1, 2017 31, 2020 were collected monitoring station City. Meteorological was obtained Bureau including...
In bearing capacity testing of prestressed concrete pipe piles, grouting material is filled up to the bottom pile, which equipped with a finishing rolled rebar. The reaction force beam transferred anchor pile through bonding between rebar and material. Therefore, investigating properties essential remove barriers application method in pile. this study, 11 groups specimens were studied pull-out tests, effects cover thickness, diameter, anchorage length reinforcement on bond strength as well...
To investigate the association between exposure to atmospheric pollutants and preterm birth in a river valley-type city its critical windows. A retrospective cohort study was used collect data from medical records of full-term deliveries two hospitals urban areas typical January 2018 December 2019. total 7,288 cases were included with general information such as pregnancy times, number cesarean sections, occupation, season conception regularity menstrual cycle. And confounding factors...
Purpose The relationship between exposure doses of 2.5-micrometer Particulate Matter (PM
A new type of stiffening rib is proposed to improve the mechanical performance T-shaped concrete-filled steel tubular (CFST) columns. finite element model was established using general-purpose commercial software ABAQUS 2022. After verification through comparison with experimental data, developed employed numerically evaluate CFST short columns ribs under axial compression. The results indicated that are capable significantly reducing buckling deformation tube, enhancing confinement effect...
To make the bearing capacity tests safer and more affordable for prestressed high-strength concrete (PHC) piles, this paper proposes a reaction device anchor piles filled with core grout based on geometric mechanical characteristics of PHC piles. The proposed has advantages convenient construction, strong controllability connection quality low cost. In addition, pile will not experience prestress unloading or tensile stress under effect upward pulling load. promote application developed...
Objective Pollutants in the atmosphere have been linked to poor pregnancy outcomes women. However, such investigations are scarce metropolitan northern China. The major exposure window of air pollution affecting pregnant women is also unknown.
With the rapid development of computer technology and further educational reform in China, more colleges or universities start to employ computers for foreign language teaching learning. This paper, thus, first briefly introduces evolution CALL, then examines constructive value drawbacks computer-assisted learning, finally emphasizes some rational cognition implications conclusion. Key words: review, benefits, drawbacks, recognition Resume: Avec le developpement rapide de la technologie...
Uranium (U) is of vital importance for the nuclear power industry. Its mining, processing and disposal impose significant risks to environment. Precipitation fate uranium in water bodies are interest environmental protection. In this work, we propose that fulvic acid (FA), a natural organic matter, can photo-precipitate ~93.2% U under anoxic conditions within 3 h ~88.3% oxic 48 h, respectively. Based on HRTEM, SAED XPS analyses precipitate, U2O5 UO2(OH)2 nanocrystals precipitate with FA its...
