1Theoretical prediction of wear of disc cutters in tunnel boring machine and its application显示文摘Predicting the cutter consumption and the exact time to replace the worn-out cutters in tunneling projects constructed with tunnel boring machine(TBM) is always a challenging issue. In this paper, we focus on the analyses of cutter motion in the rock breaking process and trajectory of rock breaking point on the cutter edge in rocks. The analytical expressions of the length of face along which the breaking point moves and the length of spiral trajectory of the maximum penetration point are derived. Through observation of rock breaking process of disc cutters as well as analysis of disc rock interaction, the following concepts are proposed: the arc length theory of predicting wear extent of inner and center cutters, and the spiral theory of predicting wear extent of gage and transition cutters. Data obtained from5621 m-long Qinling tunnel reveal that among 39 disc cutters, the relative errors between cumulatively predicted and measured wear values for nine cutters are larger than 20%, while approximately 76.9% of total cutters have the relative errors less than 20%. The proposed method could offer a new attempt to predict the disc cutter's wear extent and changing time.Zhaohuang Zhang Muhammad Aqeel Cong Li Fei Sun 2019Journal of Rock Mechanics and Geotechnical Engineering2019,11,1:6
2p38MAPK对轻度热应激大鼠脾脏巨噬细胞免疫功能的影响显示文摘目的:探讨p38MAPK在Bip蛋白介导的体外轻度热应激大鼠巨噬细胞功能改变中的信号作用.方法:p38MAPK抑制剂预处理大鼠脾脏巨噬细胞,将细胞置于41℃恒温箱中,使细胞轻度热应激,1h后恢复到37℃(抑制组),以未应激(对照组)和41℃热应激1h后60min巨噬细胞(应激组)为对照,分别检测3组巨噬细胞吞噬、杀伤、趋化功能,同时检测p38MAPK蛋白和Bip蛋白的表达.结果:p38MAPK抑制剂预处理大鼠脾脏巨噬细胞,与应激组比较,轻度热应激后巨噬细胞吞噬、趋化和杀伤活性明显降低(0.17±0.01vs0.74±0.03,33.32±3.55vs82.07±5.17,24.20%±2.39%vs60.80%±4.02%,均P<0.01);应激组p38MAPK蛋白表达明显上调,p38MAPK抑制剂预处理后,抑制组p38MAPK蛋白表达受到抑制,与应激组比较差异有显著性(p38/β-actin:2.863±0.794vs4.752±1.386,P<0.01);Bip蛋白的表达(Bip/β-actin)也因p38MAPK抑制剂预处理而由应激组的1.270±0.535降至抑制组的1.028±1.061(P<0.05).结论:p38MAPK抑制剂可显著抑制轻度热应激大鼠巨噬细胞吞噬、趋化和杀伤功能以及p38MAPK和Bip蛋白的表达.黄长文 蔡成行 李光明 Aqeel Ahmed 李惠珍 傅华群 2009世界华人消化杂志2009,17,17:4

4流动空气与风力发电叶片作用特性研究显示文摘流动空气与风力发电叶片作用特性是风力发电叶片设计的基础,是风力发电领域研究的难题。长期以来以动量-叶素理论为基础,以流过风力发电叶片空气流场为对象,相继建立了叶片优化设计的Schmitz方法、Glauert方法、Wilson方法和CFD方法等。但流经叶片过程中的空气对叶片作用的特性仍有许多问题需要亟待解决和深入研究。为此,论文应用伯努利方程推导了环状流动空气流过风力发电风轮时传递给风轮的能量计算解析式;应用动量矩原理推导了环状流动空气流过风力发电风轮时作用在风轮上的力矩解析式;提出了流过风轮的环状空气向风轮释放功率的解析式,从而发现风轮正常工作时,流过风轮的环状空气向风轮释放的功率等于环状空气流量、空气密度、环缘处风轮的牵连运动速度及环缘处流出空气的绝对运动速度在此点牵连运动速度方向上投影的连乘积。为叶片截面轮廓曲线后边缘特征参数设置提供了参考。Muhammad Aqeel 高延伟 李永强 刘青 张照煌 2017中国水利水电科学研究院学报2017,15,6:3

7Effects of the actuation waveform on the drop size reduction in drop-on-demand inkjet printing显示文摘In this study the effects of the actuation waveforms on the droplet generation in a drop-on-demand inkjet printing are studied systematically by numerical simulations.Two different types of waveforms,namely the unipolar and bipolar actuations,are investigated for three fluids with different physical properties.We focus on two key parameters,which are the dwell time and the velocity amplitude.For the unipolar driving,the ejection velocity and the ejected liquid volume are both increased as the velocity amplitude becomes larger.The dwell time only has minor effects on both the ejection velocity and the ejected liquid volume.The ejection velocity decreases significantly for large liquid viscosity,while the influences of viscosity on the ejected liquid volume are much weaker.Four different droplet morphologies and the corresponding parameter ranges are identified.The droplet radius can be successfully reduced to about 40%e of the nozzle exit radius.For the bipolar waveforms,same droplet morphologies are observed but with shifted boundaries in the phase space.The minimal radius of stable droplet produced by the bipolar waveforms is even smaller compared to the unipolar ones.Anas Bin Aqeel Muhammad Mohasan Pengyu Lv Yantao Yang Huiling Duan 2020Acta Mechanica Sinica2020,36,5:2

10Epidemiological Analysis of the Coronavirus Disease Outbreak with Random Effects显示文摘Today,coronavirus appears as a serious challenge to the whole world.Epidemiological data of coronavirus is collected through media and web sources for the purpose of analysis.New data on COVID-19 are available daily,yet information about the biological aspects of SARS-CoV-2 and epidemiological characteristics of COVID-19 remains limited,and uncertainty remains around nearly all its parameters’values.This research provides the scientic and public health communities better resources,knowledge,and tools to improve their ability to control the infectious diseases.Using the publicly available data on the ongoing pandemic,the present study investigates the incubation period and other time intervals that govern the epidemiological dynamics of the COVID-19 infections.Formulation of the testing hypotheses for different countries with a 95%level of condence,and descriptive statistics have been calculated to analyze in which region will COVID-19 fall according to the tested hypothesized mean of different countries.The results will be helpful in decision making as well as in further mathematical analysis and control strategy.Statistical tools are used to investigate this pandemic,which will be useful for further research.The testing of the hypothesis is done for the differences in various effects including standard errors.Changes in states’variables are observed over time.The rapid outbreak of coronavirus can be stopped by reducing its transmission.Susceptible should maintain safe distance and follow precautionary measures regarding COVID-19 transmission.Muhammad Farman Aqeel Ahmad Ali Akgül Muhammad Umer Saleem Muhammad Naeem Dumitru Baleanu 2021Computers, Materials & Continua2021,,6:1
11Amblyopia screening for first and second-grade children in Jordan显示文摘AIM:To share the results of a national screening program for amblyopia in school children in the north of Jordan.METHODS:This is a prospective national screening study for amblyopia.The program rolls first and second-grade children(6 to 7 years old) in the north of Jordan.The eye examination included:best-corrected visual acuity,cover-uncover test,and cycloplegic retinoscopy.Monocular visual acuity was tested using an ETDRS visual acuity chart without correction.Moreover,children were tested with full cycloplegic refraction when the test criteria were met.Unilateral amblyopia was defined as a best-corrected visual acuity difference of 2 or more lines.In comparison,bilateral amblyopia was defined as a best-corrected visual acuity of 20/40 or worse in the best eye.RESULTS:The prevalence of amblyopia for the total sample tested(n=17 203) was 2.78%(n=479).The most common cause of amblyopia was hypermetropia(64.45%),followed by previous ocular surgeries(15.1%),myopia(10.43%),strabismus(9.39%),and congenital cataract(0.63%).CONCLUSION:This is the first and only study,identifing modifiable risk factors in Jordanian children with amblyopia.In their first couple of years of elementary education,many Jordanian children are affected by amblyopia and pass unnoticed.A more governmental effort is needed into screening programs to improve vision in the Jordanian population.Khalil M.Al-Salem Mohammad S.Saleem Ismat Ereifej Hamzeh M.Alrawashdeh Rayed Falah Hussein Obeidat Asma Ali Abdlmohdi Raeda Zaki Al-Momani Layal Mohammed Hammad Omar Ahmad al-Habahbeh Yaqeen M.Assassfeh Laith Ramzi Najib Al-Qsous Ashraf Hatim Adeeb Nasraween Tariq A.Al Maaitah Deya'-Aldin Muneer Hasan Aqeel Ibtehal Eyadeh Awad Alabdulrazzg Abdullah Mahmoud Mohammad Murad Amany Jehad Faleh AL-Zurqan Enas Jamal Mohammad Jaradat Slsabela Emad Suliman Aldhoon Ala'a Majed Dmour Ahmad Talal Asassfeh Jeries Ayman Halaseh Abdel Aziz Ammar Daoud Waha Ayman Alkasasbeh Kholoud GH.Matar 2022International Journal of Ophthalmology(English edition)2022,15,2:1
