Yttria Tetragonal Zirconia Biomaterials:Kinetic Investigation

Journal of Materials science & Technology 2011年第4期27卷 332-337页

作者： Ezzat s.Elshazly s.M.El-Hout M.El-sayed ali Department of Mechanical Engineering Virginia Commonwealth University Deptartment of Metallurgy Nuclear Research CenterAtomic Energy Authority

The low temperature aging behavior of polycrystalline tetragonal zirconia was investigated to explore the effects on phase transformation occurring during the process. XRD analysis was conducted for the phase identification and the tetragonal to monoclinic phase transformation was determined. The aging of tetragonal zirconia polycrystals doped with 3 mol% Y203 triggers tetragonal to monoclinic phase transformation on the surface of the specimen only, while the penetration inside the bulk of the specimen is very limited. A slight decrease in the mechanical properties was also observed after aging for 40 h. The transformation kinetics show a nucleation and growth mechanism on the specimen surface to be dominant in the low temperature aging in water environment.

Journal of Zhejiang University-science A(Applied Physics & Engineering) 2006年第8期7卷 1329-1335页

This paper reports investigation conducted to study the fatigue performance of steel fibre reinforced concrete (sFRC) containing fibres of mixed aspect ratio. An extensive experimental program was conducted in which 90 flexural fatigue tests were carried out at different stress levels on size 500 mm×100 mm×100 mm sFRC specimens respectively containing 1.0%, 1.5% and 2.0% volume fraction of fibres. About 36 static flexural tests were also conducted to determine the static flexural strength prior to fatigue testing. Each volume fraction of fibres incorporated corrugated mixed steel fibres of size 0.6 mm×2.0 mm×25 mm and 0.6 mm×2.0 mm×50 mm in ratio 50:50 by weight. The results are presented both as s-N relationships, with the maximum fatigue stress expressed as a percentage of the strength under static loading, and as relationships between actually applied fatigue stress and number of loading cycles to failure. Two-million-cycle fatigue strengths of sFRC containing different volume fractions of mixed fibres were obtained and compared with plain concrete.

地层损害主要是通过不稳定试井来测量的，测得的地层损害程度称为表皮因子。为降低费用及作业风险，很多井都是采用地面关井和井底压力测量方法进行试井。如果设计合理，操作解释正确，测试值是非常有价值的。

Growth and Characterization of Organic NLO Crystal:β-Naphthol

Journal of Materials science & Technology 2011年第3期27卷 271-274页

作者： s.Janarthanan R.sugaraj samuel s.selvakumar Y.C.Rajan D.Jayaraman s.Pandi Department of Physics Presidency College Department of Chemistry Presidency College Department of Physics L.N.Govt.College Department of Material science Engineering National Chiao Tung University

single crystals of β-Naphthol （/3N）, an organic nonlinear optical （NLO） material was successfully grown by temperature lowering method using chloroform as solvent. The initial compound was purified by repeated recrystallization process. As-grown crystals were characterized by single crystal X-ray diffraction （XRD） studies to ascertain that βN crystal crystallized in the monoclinic system with a noncemtrosymmetric space group. Vibrational frequencies of various functional groups in the crystals were derived from Fourier transform infrared （FTIR） spectroscopy and proton nuclear magnetic resonance （NMR） spectrum. Optical characterization was done using UV-Visible near-infrared （NIR） spectroscopy. The thermal behaviour of the material was studied by thermo gravimetric and differential thermal plots. scanning electron microscopy （sEM） study was carried out on the surface of the grown crystals to investigate the nature of defects in the crystal surface and the NLO property of the crystal was tested by Nd：YAG laser as a source.

食品和饲料安全是世界性的重大课题,它提升了人们对控制食品和饲料霉菌毒素污染的关注,因为霉菌毒素污染会影响动物和人类的健康。呕吐毒素（DON）是镰刀霉菌毒素中的一种,对人体和多种动物有毒,猪对这种毒素最为敏感,鸡的耐受性最高。在欧洲,谷物通常含有呕吐毒素,因此是镰刀菌毒素污染的指标之一。人和动物摄入呕吐毒素通常会产生多种中毒症状,如肠道黏膜刺激或坏死、腹泻、呕吐及、食量下降、增重下降和免疫功能改变。

Dosimetric Comparison of Intensity-Modulated Radiotherapy versus Three-Dimensional Conformal Radiotherapy for Patients with Brain Tumors

引用

Open Journal of Radiology 2014年第1期4卷 85-96页

作者： Doaa M. al Zayat Ehab M. Attalla Hassan s. Abouelenein Yasser M.

Purpose: To compare target dose distribution and dose to normal tissue for brain tumors using intensity-modulated and three-dimensional conformal radiotherapy. Methods and Materials: Twelve patients selected in the present study compared the dosimetry of intensity-modulated radiation therapy (IMRT) and three-dimensional conformal radiation therapy (3DCRT) techniques in patients treated with different diagnosis brain tumor. all patients underwent computed tomography planning in conjunction with magnetic resonance imaging fusion. Prescription dose and normal-tissue constraints were identical for both plans. The tolerance level for maximum dose was 6.0 Gy for lenses and 54.0 Gy for brain stem, and optical nerves. Target coverage was evaluated with the D98%, D95% and D2%. Normal tissue dose was evaluated with the maximum dose to lenses, brain stem, and optical nerves. Results: Mean and standard deviation values of PTV 98%, PTV 95% and PTV 2% in IMRT these values were 94.6 ± 2.3, 96.56 ± 1.67 and 106.5 ± 1.87 respectively;for 3DCRT were 92.7 ± 3.09, 95.58 ± 1.24 and 104.45 ± 2.73 respectively. IMRT plan provided reduced dose to brainstem (72.17 ± 29.967) and lenses (2.43 ± 2.39) relative to the 3DCRT plans for brainstem (73.05 ± 34.59) and lenses (7.65 ± 23.24). But optic nerves with IMRT significantly received higher doses (38.86 ± 32.15) than 3D-CRT (27.57 ± 31.45). Conclusion: Dose coverage of the planning target volume (PTV) and organ at risk (OAR) was better with IMRT. If PTV is distant to optical nerves and brainstem 3DCRT technique can be applied, and if the PTV is nearby OAR intensity-modulated treatment technique should be used.
