Purpose:Dental and orofacial trauma among the adult population constitutes a major public health problem. The impact is not just physical but also psychological. To analyse the impacts of dental and orofacial trauma on oral health-related quality of life (OHRQoL) in adults and determine whether the 2 variables are closely ***:This is a systematic review. The terms "dental trauma", "orofacial trauma", "oral health", "oral health related impact life", "OHRQoL", "positive and negative affect scale", "quality of life", "facial injuries", "adults", and "young adults" were researched in the databases of PubMed, ScienceDirect, Scopus and Google Scholar for associated studies up to December 30, 2022. A comprehensive search was designed and the articles were independently screened for eligibility by 2 reviewers. The included studies’ author, year of publication, the country where the study was conducted, population demographics (number and age), an instrument used for assessing OHRQoL and the relevant result were recorded and compared. The quality of the evidence was assessed using Joanna Briggs Institute checklist for observational ***:Out of 482 unique records, 3 articles were included for data extraction. Observational studies were included. Two studies did not mention confounding factors. Different scales were used for dental and orofacial trauma and OHRQoL. OHRQoL has a directly proportional relationship with orofacial trauma. Adolescents with orofacial trauma have a significant impact on this value with a prevalence of 88.4%.Conclusion:The highest impact on OHRQoL was seen immediately after the diagnosis of an orofacial trauma. The impact increases with the severity of the trauma. Therefore, to promote overall dental and general health, health education initiatives should include information on the causes, prevention, and requirement for prompt responses by the populace in seeking dental intervention.

Analyzing hydro abrasive erosion in Kaplan turbine:A case study from India

引用

Journal of Hydrodynamics 2016年第5期28卷 863-872页

作者： Anant Kr.rai Arun kumar Alternate Hydro Energy Centre IIT Roorkee

Sediment flow through hydro turbine causes erosion of hydraulic components resulting in drop of turbine efficiency, parti- cularly in hydropower plants of the Himalayan region. The measurement of erosion and monitoring of sediment flow in turbine are major concerns in erosion study. Attempts have been made to study erosion mainly in Pelton and Francis turbines. In this study, a simple and effective method has been presented to measure erosion in a Kaplan turbine of a run-of-river scheme Chilla hydropower plant in foothills of Himalaya. Recent techniques were used to measure sediment parameters like concentration, size, shape and mineral content. A standard erosion model is applied to estimate the erosion in Kaplan turbine blade, runner chamber and draft tube cone. A calibration factor has been proposed to apply the erosion model for site specific conditions. It has been found that the outer trailing edges of the turbine blade and upper rtmner chamber are most erosion prone zones. Sediment analysis revealed that effective operation can reduce erosion in turbine components. The estimated erosion values from model are found to be consistent with measu- red values. Finally, suggestions for design improvements and effective operation of erosion affected hydropower plants are given.

Determination of the particle load based on detailed suspended sediment measurements at a hydropower plant

引用

International Journal of Sediment Research 2019年第5期34卷 409-421页

作者： Anant kumar rai Arun kumar Alternate Hydro Energy Centre

Suspended sediment particles contained in inflows of water systems of hydropower plants(HPPs) cause hydro-abrasive erosion of the hydraulic turbines and structures leading to significant maintenance costs,efficiency reductions, and downtime. Relevant parameters such as suspended sediment concentration(SSC), particle size distribution(PSD), shape, and mineralogical composition were measured with an online multi-frequency acoustic instrument and based on manually taken samples from the end of the sand trap of the Toss HPP in the Himalayan region, India. In the laboratory, the samples were analyzed using the gravimetric method, laser diffraction, turbidity, dynamic digital image processing, scanning electron microscope, petrography analysis, energy-dispersive X-ray spectroscopy, and X-ray *** online instrument and the samples provided measurement results at a single point. To investigate vertical gradients in concentration and particle sizes, additional samples were collected 9 times at 7 relative water depths. The SSC, most particle sizes, and particle shape were found to be evenly distributed over depth except d90, i.e. the diameter which is not exceeded by 90% of the particle mass. d90 measured at 76% of the water depth was in the range of fine sand and was multiplied by 1.05 to obtain an average value representative for the entire depth. Improved methodologies to quantify both particle shape and size in an analytical model for hydro-abrasive erosion are proposed. Also, the PSD measuring performance of laser diffraction and dynamic imaging was studied and similar values of the median particle sizes were obtained from both instruments. Further, multi-frequency acoustic, turbidity and laser diffraction techniques were found suitable for SSC measurement at the test case HPP.

Er^(3+)/Yb^(3+)/Li^+/Zn^(2+):Gd_2(MoO_4)_3 upconverting nanophosphors in optical thermometry

引用

Journal of Rare Earths 2019年第3期37卷 242-247页

作者： Anita kumari Lakshmi Mukhopadhyay Vineet kumar rai Laser and Spectroscopy Laboratory Department of Applied Physics Indian Institute of Technology (Indian School of Mines)

Er^(3+)-Yb^(3+)-Li^+:Gd_2(MoO_4)_3 and Er^(3+)-Yb^(3+)-Zn^(2+):Gd_2(MoO_4)_3 nanophosphors, synthesized by chemical co-precipitation technique were characterized through XRD,FESEM,dynamic light scattering(DLS),diffuse reflectance, photoluminescence, photometric and decay time analysis. The enhancement of about～28, ～149 and ～351 times in the green upconversion emission band is observed for the optimized Er^(3+)-Yb^(3+),Er^(3+)-Yb^(3+)-Li^+ and Er^(3+)-Yb^(3+)-Zn^(2+):Gd_2(MoO_4)_3 nanophosphors in comparison to the singly Er^(3+) doped nanophosphors. The electric dipole-dipole interaction is found to be responsible for the concentration quenching. The temperature dependent behaviour of the two green thermally coupled levels of the Er^(3+) ions based on the fluorescence intensity ratio technique was studied. The maximum sensor sensitivity ～38.7 × 10^(-3) K^(-1) at 473 K for optimized Er^(3+)-Yb^(3+)-Zn^(2+) codoped Gd_2(MoO_4)_3 nanophosphors is reported with maximum population redistribution ability～88% among the ~2H_(11/2) and ~4S_(3/2) levels.
