| 1 | A Reliable Stochastic Numerical Analysis for Typhoid Fever Incorporating With Protection Against Infection显示文摘In this paper,a reliable stochastic numerical analysis for typhoid fever incorporating with protection against infection has been considered.We have compared the solutions of stochastic and deterministic typhoid fever model.It has been shown that the stochastic typhoid fever model is more realistic as compared to the deterministic typhoid fever model.The effect of threshold number T*hold in stochastic typhoid fever model.The proposed framework of the stochastic non-standard finite difference scheme(SNSFD)preserves all dynamical properties like positivity,bounded-ness and dynamical consistency defined by Mickens,R.E.The stochastic numerical simulation of the model showed that increase in protection leads to low disease prevalence in a population. | Muhammad Shoaib Arif Ali Raza Muhammad Rafiq Mairaj Bibi Rabia Fayyaz Mehvish Naz Umer Javed | 2019 | Computers, Materials & Continua2019，，6： | 3 |
| 2 | Screening of textile finishing agents available on the Chinese market: An important source of per-and polyfluoroalkyl substances to the environmentpolyfluoroalkyl substances to the environment显示文摘Organofluorinated surfactants are widely employed in textile finishing agents (TFAs) to achieve oil, water, and stain repellency. This has been regarded as an important emission source of per-and polyfluoroalkyl substances (PFASs) to the environment. China is the biggest manufacturer of clothes, and thus TFA production is also a relevant industrial activity. Nevertheless, to date, no survey has been conducted on PFAS contents in commercially available TFAs. In the present study, TFA products were investigated by the Kendrick mass defect method. The quantification results demonstrated a significant presence of perfluorooctane sulfonate (0.37 mg/L) in TFAs manufactured by electrochemical fluorination technology. The products obtained by short-chain PFAS-based telomerization were dominated by perfluorooctanoic acid (mean concentration: 0.29 mg/L), whose values exceeded the limits stated in the European Chemical Agency guidelines (0.025 mg/L). Moreover, the total oxidizable precursor assay indicated high levels of indirectly quantified precursors with long alkyl chains (C7–C9). Together, these results suggest that there is currently a certain of environmental and health risks in China that originates from the utilization of TFAs, and a better manufacturing processes are required to reduce such risks. | Mehvish Mumtaz Yixiang Bao Wenchao Li Lingxiao Kong Jun Huang Gang Yu | 2019 | Frontiers of Environmental Science & Engineering2019，13，5： | 1 |

| 4 | Computational Algorithms for the Analysis of Cancer Virotherapy Model显示文摘Cancer is a common term for many diseases that can affect any part of the body.In 2020,ten million people will die due to cancer.A worldwide leading cause of death is cancer by the World Health Organization(WHO)report.Interaction of cancer cells,viral therapy,and immune response are identified in this model.Mathematical and computational modeling is an effective tool to predict the dynamics of cancer virotherapy.The cell population is categorized into three parts like uninfected cells(x),infected cells(y),virus-free cells(v),and immune cells(z).The modeling of cancerlike diseases is based on the law of mass action(the rate of change of reacting substances is directly proportional to the product of interacting substances).Positivity,boundedness,equilibria,threshold analysis,are part of deterministic modeling.Later on,a numerical analysis is designed by using the standard and non-standard finite difference methods.The non-standard finite difference method is developed to study the long-term behavior of the cancer model.For its efficiency,a comparison of the methods is investigated. | Ali Raza Dumitru Baleanu Muhammad Rafiq Syed Zaheer Abbas Abubakar Siddique Umer Javed Mehvish Naz Arooj Fatima Tayyba Munawar Hira Batool Zaighum Nazir | 2022 | Computers, Materials & Continua2022，，5： | 0 |
| 5 | 碳纳米管及纳米氧化铝对硝酸盐相变材料热性能的影响显示文摘硝酸熔融盐具有良好的热物性能,在聚光太阳能发电技术中得到广泛运用,通过提高熔盐的比热容,可以提高其蓄热能力。将硝酸锂、硝酸钾和硝酸钠以共晶比52:30:18制备硝酸盐储热材料,通过添加纳米氧化铝颗粒及碳纳米管研究其对熔融盐比热的影响。通过超声振动和蒸发在硝酸熔融盐中加入纳米氧化铝颗粒和碳纳米管。采用直接合成法制备含纳米氧化铝和碳纳米管分别为0.06%、0.5%、1%和2%的硝酸盐纳米流体。通过SEM观察了纳米氧化铝颗粒及碳纳米管在硝酸盐中的分散性,当纳米氧化铝颗粒浓度为1%时发生团聚,这种团聚会影响纳米流体的比热容。碳纳米管添加量小于2%时分散性好。通过差示扫描量热仪(DSC)测量了硝酸盐纳米复合材料的比热容,纳米氧化铝浓度为1%的硝酸盐纳米流体在固态(110℃)和液态(140℃)下分别是纯硝酸盐比热容的1.44倍和3.48倍。CNTs浓度为1%的硝酸盐纳米流体在固态(110℃)和液态(140℃)下分别是纯硝酸盐比热容的5.07倍和4.17倍。DSC结果表明当纳米颗粒浓度大于1%时,纳米流体的比热降低。本研究讨论了提高纳米流体比热容的机制,得到硝酸盐比热容的增加与纳米颗粒的高比表面积和高能量相关。 | MEHVISH Tariq 程晓敏 李元元 黄毅 李戈 王秀丽 朱石磊 WAQAR Khan | 2018 | 储能科学与技术2018，7，A01： | 0 |
| 6 | Current trends and emerging methods for the detection of SARS-CoV-2 infection显示文摘Severe acute respiratory syndrome(SARS-CoV-2)is the prime cause of the current global COVID-19 pandemic originating from Wuhan,the Hubei province of China.Since then the infection has affected more than ten million people across the globe,and caused nearly half a million deaths worldwide.The virus has now spread all over the world as a pandemic.Covid-19 remains a major challenge to tackle,presently there is no antiviral treatment available.In this review we will address the current and emerging laboratory techniques for the detection of SARS-CoV-2.Real Time PCR assay commonly known as the Reverse transcriptase Assay is the gold standard and a widely accepted test clinically.Seroprevalence of the SARS-CoV-2 is performed using ELISA and antigen detection as rapid tests.In clinical practice identification of the disease is done on the basis of chest radiographs,computer tomography,(CT)and Positron Emission Tomography(PET)scans.As the pandemic has now progressed,newer methods of detection like CRISPR’s,nanotechnology enabled solutions,and biosensors have emerged as newer techniques to detect SARS-CoV-2. | Mehvish Saleem Manas Kumar Sahoo | 2021 | Infectious Diseases Research2021，2，4： | 0 |
