It has a strong connection with the noticeably growing mental health crisis of high school students. This study elucidates the relationship between gender role conflict and reports of subjective well-being of teenagers through mixed-methods empirical research based on surveys conducted in two Chinese cities, namely Shenzhen and Yuxi. These two cities are from two provinces of very distinct economic and cultural backgrounds. We believe a comparison between the two cities reveals the unequally distributed social conditions in China. We found that teenagers who possess a higher degree of gender role conflict tend to exhibit more negative emotions and that this relationship is conditioned upon other important factors such as gender, only child status, and socio-economic factors. Furthermore, we discovered that the social environment that is more progressive and open to various gender roles is correlated with higher levels of subjective well-being of teenagers in Shenzhen and Yunnan. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gender%20role%20conflict" title="gender role conflict">gender role conflict</a>, <a href="https://publications.waset.org/abstracts/search?q=mental%20health%20conditions" title=" mental health conditions"> mental health conditions</a>, <a href="https://publications.waset.org/abstracts/search?q=subjective%20well-being" title=" subjective well-being"> subjective well-being</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20environment" title=" social environment"> social environment</a> </p> <a href="https://publications.waset.org/abstracts/123586/gender-role-conflict-and-subjective-well-being-of-chinese-teenagers-a-study-based-on-high-school-students-from-guangdong-and-yunnan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/123586.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">125</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">6</span> Characterization of the Corn Cob to Know Its Potential as a Source of Biosilica to Be Used in Sustainable Cementitious Mixtures</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sandra%20C.%20L.%20Dorea">Sandra C.

Feasible materials for this purpose can include agro-industrial or agricultural wastes, which are termed 'biosilica' since the silica was contained in a biological matrix (biomass). Corn cob (CC) has some characteristics that make it a good candidate as biosilica source: 1) it is an abundant grain crop produced around the world; 2) more production means more available residues is left in the field to be used. This work aims to evaluate the CC collected from different farms in Canada during the corn harvest in order to see if they can be used together as a biosilica source. The characterization of the raw CC was made in the physical, chemical, and thermal way. The moisture content, the granulometry, and the morphology were also analyzed. The ash content measured was 2,1%. The Thermogravimetric Analysis (TGA) and its Derivative (DTG) evaluated of CC as a function of weight loss with temperature variation ranging between 30°C and 800°C in an atmosphere of N2. The chemical composition and the presence of silica revealed that the different sources of the CC do not interfere in its basic chemical composition, which means that this kind of waste can be used together as a source of biosilica no matter where they come from. Then, this biosilica can partially replace the cement Portland making sustainable cementitious mixtures and contributing to reduce the CO2 emissions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biosilica" title="biosilica">biosilica</a>, <a href="https://publications.waset.org/abstracts/search?q=characterization" title=" characterization"> characterization</a>, <a href="https://publications.waset.org/abstracts/search?q=corn%20cob" title=" corn cob"> corn cob</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainable%20cementitious%20materials" title=" sustainable cementitious materials"> sustainable cementitious materials</a> </p> <a href="https://publications.waset.org/abstracts/57988/characterization-of-the-corn-cob-to-know-its-potential-as-a-source-of-biosilica-to-be-used-in-sustainable-cementitious-mixtures" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57988.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">262</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5</span> Effect of Nicotine on the Reinforcing Effects of Cocaine in a Nonhuman Primate Model of Drug Use</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mia%20I.%20Allen">Mia I.

While the majority of people with CUD also use tobacco/nicotine, the majority of preclinical cocaine research does not include the co-use of nicotine. The present study examined nicotine and cocaine co-use under several conditions of intravenous drug self-administration in monkeys. In Experiment 1, male rhesus monkeys (N=3) self-administered cocaine (0.001-0.1 mg/kg/injection) alone and cocaine+nicotine (0.01-0.03 mg/kg/injection) under a progressive-ratio schedule of reinforcement. When nicotine was added to cocaine, there was a significant leftward shift and significant increase in peak break point. In Experiment 2, socially housed female and male cynomolgus monkeys (N=14) self-administered cocaine under a concurrent drug-vs-food choice schedule. Combining nicotine significantly decreased cocaine choice ED50 values (i.e., shifted the cocaine dose-response curve to the left) in females but not in males. There was no evidence of social rank differences. In delay discounting studies, the co-use of nicotine and cocaine required significantly larger delays to the preferred drug reinforcer to reallocate choice compared with cocaine alone. Overall, these results suggest drug interactions of nicotine and cocaine co-use is not simply a function of potency but rather a fundamentally distinctive condition that should be utilized to better understand the neuropharmacology of CUD and the evaluation of potential treatments. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=polydrug%20use" title="polydrug use">polydrug use</a>, <a href="https://publications.waset.org/abstracts/search?q=animal%20models" title=" animal models"> animal models</a>, <a href="https://publications.waset.org/abstracts/search?q=nonhuman%20primates" title=" nonhuman primates"> nonhuman primates</a>, <a href="https://publications.waset.org/abstracts/search?q=behavioral%20pharmacology" title=" behavioral pharmacology"> behavioral pharmacology</a>, <a href="https://publications.waset.org/abstracts/search?q=drug%20self-administration" title=" drug self-administration"> drug self-administration</a> </p> <a href="https://publications.waset.org/abstracts/168771/effect-of-nicotine-on-the-reinforcing-effects-of-cocaine-in-a-nonhuman-primate-model-of-drug-use" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/168771.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">87</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4</span> Effect of Minerals in Middlings on the Reactivity of Gasification-Coke by Blending a Large Proportion of Long Flame Coal</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jianjun%20Wu">Jianjun Wu</a>, <a href="https://publications.waset.org/abstracts/search?q=Fanhui%20Guo"> Fanhui Guo</a>, <a href="https://publications.waset.org/abstracts/search?q=Yixin%20Zhang"> Yixin Zhang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, gasification-coke were produced by blending the middlings (MC), and coking coal (CC) and a large proportion of long flame coal (Shenfu coal, SC), the effects of blending ratio were investigated. Mineral evolution and crystalline order obtained by XRD methods were reproduced within reasonable accuracy. Structure characteristics of partially gasification-coke such as surface area and porosity were determined using the N₂ adsorption and mercury porosimetry. Experimental data of gasification-coke was dominated by the TGA results provided trend, reactivity differences between gasification-cokes are discussed in terms of structure characteristic, crystallinity, and alkali index (AI). The first-order reaction equation was suitable for the gasification reaction kinetics of CO₂ atmosphere which was represented by the volumetric reaction model with linear correlation coefficient above 0.985. The differences in the microporous structure of gasification-coke and catalysis caused by the minerals in parent coals were supposed to be the main factors which affect its reactivity. The addition of MC made the samples enriched with a large amount of ash causing a higher surface area and a lower crystalline order to gasification-coke which was beneficial to gasification reaction. The higher SiO₂ and Al₂O₃ contents, causing a decreasing AI value and increasing activation energy, which reduced the gasification reaction activity. It was found that the increasing amount of MC got a better performance on the coke gasification reactivity by blending > 30% SC with this coking process. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=low-rank%20coal" title="low-rank coal">low-rank coal</a>, <a href="https://publications.waset.org/abstracts/search?q=middlings" title=" middlings"> middlings</a>, <a href="https://publications.waset.org/abstracts/search?q=structure%20characteristic" title=" structure characteristic"> structure characteristic</a>, <a href="https://publications.waset.org/abstracts/search?q=mineral%20evolution" title=" mineral evolution"> mineral evolution</a>, <a href="https://publications.waset.org/abstracts/search?q=alkali%20index" title=" alkali index"> alkali index</a>, <a href="https://publications.waset.org/abstracts/search?q=gasification-coke" title=" gasification-coke"> gasification-coke</a>, <a href="https://publications.waset.org/abstracts/search?q=gasification%20kinetics" title=" gasification kinetics"> gasification kinetics</a> </p> <a href="https://publications.waset.org/abstracts/100113/effect-of-minerals-in-middlings-on-the-reactivity-of-gasification-coke-by-blending-a-large-proportion-of-long-flame-coal" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/100113.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">175</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3</span> Application of Customized Bioaugmentation Inocula to Alleviate Ammonia Toxicity in CSTR Anaerobic Digesters</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yixin%20Yan">Yixin Yan</a>, <a href="https://publications.waset.org/abstracts/search?q=Miao%20Yan"> Miao Yan</a>, <a href="https://publications.waset.org/abstracts/search?q=Irini%20Angelidaki"> Irini Angelidaki</a>, <a href="https://publications.waset.org/abstracts/search?q=Ioannis%20Fotidis"> Ioannis Fotidis</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Ammonia, which derives from the degradation of urea and protein-substrates, is the major toxicant of the commercial anaerobic digestion reactors causing loses of up to 1/3 of their practical biogas production, which reflects directly on the overall revenue of the plants. The current experimental work is aiming to alleviate the ammonia inhibition in anaerobic digestion (AD) process by developing an innovative bioaugmentation method of ammonia tolerant methanogenic consortia. The ammonia tolerant consortia were cultured in batch reactors and immobilized together with biochar in agar (customized inocula). Three continuous stirred-tank reactors (CSTR), fed with the organic fraction of municipal solid waste at a hydraulic retention time of 15 days and operated at thermophilic (55°C) conditions were assessed. After an ammonia shock of 4 g NH4+-N L-1, the customized inocula were bioaugmented into the CSTR reactors to alleviate ammonia toxicity effect on AD process. Recovery rate of methane production and methanogenic activity will be assessed to evaluate the bioaugmentation performance, while 16s rRNA gene sequence will be used to reveal the difference of microbial community changes through bioaugmentation. At the microbial level, the microbial community structures of the four reactors will be analysed to find the mechanism of bioaugmentation. Changes in hydrogen formation potential will be used to predict direct interspecies electron transfer (DIET) between ammonia tolerant methanogens and syntrophic bacteria. This experimental work is expected to create bioaugmentation inocula that will be easy to obtain, transport, handled and bioaugment in AD reactors to efficiently alleviate the ammonia toxicity, without alternating any of the other operational parameters including the ammonia-rich feedstocks. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=artisanal%20fishing%20waste" title="artisanal fishing waste">artisanal fishing waste</a>, <a href="https://publications.waset.org/abstracts/search?q=acidogenesis" title=" acidogenesis"> acidogenesis</a>, <a href="https://publications.waset.org/abstracts/search?q=volatile%20fatty%20acids" title=" volatile fatty acids"> volatile fatty acids</a>, <a href="https://publications.waset.org/abstracts/search?q=pH" title=" pH"> pH</a>, <a href="https://publications.waset.org/abstracts/search?q=inoculum%2Fsubstrate%20ratio" title=" inoculum/substrate ratio"> inoculum/substrate ratio</a> </p> <a href="https://publications.waset.org/abstracts/125008/application-of-customized-bioaugmentation-inocula-to-alleviate-ammonia-toxicity-in-cstr-anaerobic-digesters" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/125008.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">127</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2</span> Demonstrating the Efficacy of a Low-Cost Carbon Dioxide-Based Cryoablation Device in Veterinary Medicine for Translation to Third World Medical Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Grace%20C.%20Kuroki">Grace C.

This study was approved by the institutional animal care and use committee. Client-owned dogs with subcutaneous masses, primarily lipomas or mammary cancers, were recruited for the study. Inclusion was based on clinical history, lesion location, preanesthetic blood work, and fine needle aspirate or biopsy confirmation of mass. Informed consent was obtained from the owners for dogs that met inclusion criteria. Ultrasound assessment of mass extent was performed immediately prior to mass cryoablation. Dogs were placed under general anesthesia and sterilely prepared. A stab incision was created to insert a custom 4.19 OD x 55.9 mm length cryoablation probe (Kubanda Cryotherapy) into the mass. Originally designed for treating breast cancer in low resource settings, this device has demonstrated potential in effectively necrosing subcutaneous masses. A dose escalation study of increasing freeze-thaw cycles (5/4/5, 7/5/7, and 10/7/10 min) was performed to assess the size of the iceball/necrotic extent of cryoablation. Each dog was allowed to recover for ~1-2 weeks before surgical removal of the mass. A single mass was treated in seven dogs (2 mammary masses, a sarcoma, 4 lipomas, and 1 adnexal mass) with most masses exceeding 2 cm in any dimension. Mass involution was most evident in the malignant mammary and adnexal mass. Lipomas showed minimal shrinkage prior to surgical removal, but an area of necrosis was evident along the cryoablation probe path. Gross assessment indicated a clear margin of cryoablation along the cryoprobe independent of tumor type. Detailed histopathology is pending, but complete involution of large lipomas appeared to be unlikely with a 10/7/10 protocol. The low-cost, carbon dioxide-based cryotherapy device permits a minimally invasive technique that may be useful for veterinary applications but is also informative of the unlikely resolution of benign adipose breast masses that may be encountered in third world countries. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cryoablation" title="cryoablation">cryoablation</a>, <a href="https://publications.waset.org/abstracts/search?q=cryotherapy" title=" cryotherapy"> cryotherapy</a>, <a href="https://publications.waset.org/abstracts/search?q=interventional%20oncology" title=" interventional oncology"> interventional oncology</a>, <a href="https://publications.waset.org/abstracts/search?q=veterinary%20technology" title=" veterinary technology"> veterinary technology</a> </p> <a href="https://publications.waset.org/abstracts/117969/demonstrating-the-efficacy-of-a-low-cost-carbon-dioxide-based-cryoablation-device-in-veterinary-medicine-for-translation-to-third-world-medical-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/117969.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">131</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1</span> Modeling Driving Distraction Considering Psychological-Physical Constraints</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yixin%20Zhu">Yixin Zhu</a>, <a href="https://publications.waset.org/abstracts/search?q=Lishengsa%20Yue"> Lishengsa Yue</a>, <a href="https://publications.waset.org/abstracts/search?q=Jian%20Sun"> Jian Sun</a>, <a href="https://publications.waset.org/abstracts/search?q=Lanyue%20Tang"> Lanyue Tang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Modeling driving distraction in microscopic traffic simulation is crucial for enhancing simulation accuracy. Current driving distraction models are mainly derived from physical motion constraints under distracted states, in which distraction-related error terms are added to existing microscopic driver models. However, the model accuracy is not very satisfying, due to a lack of modeling the cognitive mechanism underlying the distraction. This study models driving distraction based on the Queueing Network Human Processor model (QN-MHP). This study utilizes the queuing structure of the model to perform task invocation and switching for distracted operation and control of the vehicle under driver distraction. Based on the assumption of the QN-MHP model about the cognitive sub-network, server F is a structural bottleneck. The latter information must wait for the previous information to leave server F before it can be processed in server F. Therefore, the waiting time for task switching needs to be calculated. Since the QN-MHP model has different information processing paths for auditory information and visual information, this study divides driving distraction into two types: auditory distraction and visual distraction. For visual distraction, both the visual distraction task and the driving task need to go through the visual perception sub-network, and the stimuli of the two are asynchronous, which is called stimulus on asynchrony (SOA), so when calculating the waiting time for switching tasks, it is necessary to consider it. In the case of auditory distraction, the auditory distraction task and the driving task do not need to compete for the server resources of the perceptual sub-network, and their stimuli can be synchronized without considering the time difference in receiving the stimuli. According to the Theory of Planned Behavior for drivers (TPB), this study uses risk entropy as the decision criterion for driver task switching. A logistic regression model is used with risk entropy as the independent variable to determine whether the driver performs a distraction task, to explain the relationship between perceived risk and distraction. Furthermore, to model a driver’s perception characteristics, a neurophysiological model of visual distraction tasks is incorporated into the QN-MHP, and executes the classical Intelligent Driver Model. The proposed driving distraction model integrates the psychological cognitive process of a driver with the physical motion characteristics, resulting in both high accuracy and interpretability. This paper uses 773 segments of distracted car-following in Shanghai Naturalistic Driving Study data (SH-NDS) to classify the patterns of distracted behavior on different road facilities and obtains three types of distraction patterns: numbness, delay, and aggressiveness. The model was calibrated and verified by simulation. The results indicate that the model can effectively simulate the distracted car-following behavior of different patterns on various roadway facilities, and its performance is better than the traditional IDM model with distraction-related error terms. The proposed model overcomes the limitations of physical-constraints-based models in replicating dangerous driving behaviors, and internal characteristics of an individual. Moreover, the model is demonstrated to effectively generate more dangerous distracted driving scenarios, which can be used to construct high-value automated driving test scenarios. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=computational%20cognitive%20model" title="computational cognitive model">computational cognitive model</a>, <a href="https://publications.waset.org/abstracts/search?q=driving%20distraction" title=" driving distraction"> driving distraction</a>, <a href="https://publications.waset.org/abstracts/search?q=microscopic%20traffic%20simulation" title=" microscopic traffic simulation"> microscopic traffic simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=psychological-physical%20constraints" title=" psychological-physical constraints"> psychological-physical constraints</a> </p> <a href="https://publications.waset.org/abstracts/166497/modeling-driving-distraction-considering-psychological-physical-constraints" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/166497.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">91</span> </span> </div> </div> </div> </main> <footer> <div id="infolinks" class="pt-3 pb-2"> <div class="container"> <div style="background-color:#f5f5f5;" class="p-3"> <div class="row"> <div class="col-md-2"> <ul class="list-unstyled"> About <li><a href="https://waset.org/page/support">About Us</a></li> <li><a href="https://waset.org/page/support#legal-information">Legal</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/WASET-16th-foundational-anniversary.pdf">WASET celebrates its 16th foundational anniversary</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Account <li><a href="https://waset.org/profile">My Account</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Explore <li><a href="https://waset.org/disciplines">Disciplines</a></li> <li><a href="https://waset.org/conferences">Conferences</a></li> <li><a href="https://waset.org/conference-programs">Conference Program</a></li> <li><a href="https://waset.org/committees">Committees</a></li> <li><a href="https://publications.waset.org">Publications</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Research <li><a href="https://publications.waset.org/abstracts">Abstracts</a></li> <li><a href="https://publications.waset.org">Periodicals</a></li> <li><a href="https://publications.waset.org/archive">Archive</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Open Science <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Open-Science-Philosophy.pdf">Open Science Philosophy</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Open-Science-Award.pdf">Open Science Award</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Open-Society-Open-Science-and-Open-Innovation.pdf">Open Innovation</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Postdoctoral-Fellowship-Award.pdf">Postdoctoral Fellowship Award</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Scholarly-Research-Review.pdf">Scholarly Research Review</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Support <li><a href="https://waset.org/page/support">Support</a></li> <li><a href="https://waset.org/profile/messages/create">Contact Us</a></li> <li><a href="https://waset.org/profile/messages/create">Report Abuse</a></li> </ul> </div> </div> </div> </div> </div> <div class="container text-center"> <hr style="margin-top:0;margin-bottom:.3rem;"> <a href="https://creativecommons.org/licenses/by/4.0/" target="_blank" class="text-muted small">Creative Commons Attribution 4.0 International License</a> <div id="copy" class="mt-2">&copy;
