2An Investigation of Effect of Stand-Off Distance on the Material Removal Characteristics and Surface Generation in Fluid Jet Polishing显示文摘Fluid jet polishing(FJP)is a versatile polishing process that has many advantages compared to other polishing processes.Stand-off distance(SOD)is one of the key parameters in flu id jet polishi ng.However,relatively little research work has been carried out to investigate its effect of SOD on material removal characteristics and surface generation in FJP.In this paper,a systematic investigation of the effect of SOD on the tool influence function and surface topography in FJP was conducted.Experiments were designed for FJP two kinds of materials corresponding to ductile and brittle materials.They are nickel copper(NiCu)alloy and BK7 optical glass,respectively.In this study,the SOD was varied from 2 to 35 mm.Analysis and discussions were made on its effect on the shape of TIF,material removal rate,and surface topography.It is interesting to note that the TIF shape becomes a Gaussian-like shape with large SOD both on NiCu and BK7,which provides a novel way to optimize the TIF in FJP.The variation of the material removal rate and surface roughness versus SOD on NiCu and BK7 were also determined from the experimental results.Moreover,the surface topography of NiCu and BK7 were characterized from the results measured from the white light interferometer and scan electron microscope.The outcome of the study provides a better understanding of the material removal characteristics and surface generation mechanism in FJP.Chun Jin Wang Chi Fai Cheung Lai Ting Ho Yee Man Loh 2020Nanomanufacturing and Metrology2020,3,2:1

6Mothers’ health-related quality of life: Its relationship with children’s health-related quality of life and behavior in low-income families显示文摘Objective:To examine the association between mothers’health-related quality of life(HRQOL)and their children’s HRQOL and behavior in low-income families.Methods:Mothers of 278 children aged 6-12 years from low-income families were invited to complete the Child Health Questionnaire Parent Form 50(CHQ-PF50)and the Strength and Dif-ficulties Questionnaire(SDQ)for their children as well as the 12-item Short-Form Health Survey version 2(SF-12v2)and the Patient Health Questionnaire-2(PHQ-2).Multiple linear regressions with mother-child pairs as the unit of analysis were performed to examine the associations between maternal and child variables with adjustment of mother-and child-level confounders.Results:Compared with the general population,low-income mothers had a lower mean SF-12v2 mental component summary score and their children also had lower mean CHQ-PF50 physi-cal and psychosocial summary scores and SDQ total difficulties score.Children of mothers with SF-12v2 scores below the population mean of 50 had significantly worse CHQ-PF50 scores and higher SDQ total difficulties scores.The mother’s PHQ-2 depression status had no association with the child’s CHQ-PF50 scores.Conclusion:Our findings suggest that more attention should be paid to reducing the negative impact of health problems on mothers’daily roles in childcare in low-income families.Rosa Sze Man Wong Vivian Yawei Guo Patrick Ip Carlos King Ho Wong Esther Yee Tak Yu Colman Siu Cheung Fung Cindy Lo Kuen Lam 2016Family Medicine and Community Health2016,4,4:0
