1A review on machinability of carbon fiber reinforced polymer(CFRP)and glass fiber reinforced polymer(GFRP)composite materials显示文摘Fiber reinforced polymer(FRP) composite materials are heterogeneous and anisotropic materials that do not exhibit plastic deformation. They have been used in a wide range of contemporary applications particularly in space and aviation,automotive,maritime and manufacturing of sports equipment. Carbon fiber reinforced polymer(CFRP) and glass fiber reinforced polymer(GFRP) composite materials,among other fiber reinforced materials,have been increasingly replacing conventional materials with their excellent strength and low specific weight properties. Their manufacturability in varying combinations with customized strength properties,also their high fatigue,toughness and high temperature wear and oxidation resistance capabilities render these materials an excellent choice in engineering applications.In the present review study,a literature survey was conducted on the machinability properties and related approaches for CFRP and GFRP composite materials. As in the machining of all anisotropic and heterogeneous materials,failure mechanisms were also reported in the machining of CFRP and GFRP materials with both conventional and modern manufacturing methods and the results of these studies were obtained by use of variance analysis(ANOVA),artificial neural networks(ANN) model,fuzzy inference system(FIS),harmony search(HS) algorithm,genetic algorithm(GA),Taguchi's optimization technique,multi-criteria optimization,analytical modeling,stress analysis,finite elements method(FEM),data analysis,and linear regression technique. Failure mechanisms and surface quality is discussed with the help of optical and scanning electron microscopy,and profilometry. ANOVA,GA,FEM,etc. are used to analyze and generate predictive models.Meltem Altin Karatas Hasan Gokkaya 2018Defence Technology(防务技术)2018,14,4:31

3Evaluation of cardiovascular risk in patients with Parkinson disease under levodopa treatment显示文摘BackgroundLevodopa 是在有 Parkinson 疾病(PD ) 的病人的中间的治疗的不可缺少的选择。因为 L-dopa 治疗被显示增加浆液 homocysteine 层次,为心血管的混乱的一个著名风险因素,有在 L-dopa 治疗下面的 PD 的病人将在为未来的增加的风险心血管的事件。这研究的目的是在 levodopa treatment.MethodsThe 学习下面与 PD 在病人评估心血管的风险人口在 L-dopa 治疗下面与自发的 PD 由 65 个病人组成了。控制组包括了 32 年龄,性匹配没有认知衰落的个人。Echocardiographic 大小,浆液 homocysteine 层次和主动脉的有弹性的参数与 PD 和 controls.ResultsAs 在病人之间被作比较 L-dopa 治疗的一个期望的特征, Parkinson 组有显著地更高的 homocystein 层次(15.1 ±3.9 µ mol/L 对 11.5 ±3.2 µ mol/L, P = 0.02 ) 。当时,大动脉的膨胀性在有 PD 的病人是显著地更低的与控制相比(4.8 ±1.5 dyn/cm 2 对 6.2 ±1.9 dyn/cm 2, P = 0.016 ) 。另外,有 PD 的病人有更高大动脉的紧张和大动脉的僵硬索引(13.4%±6.4% 对 7.4%±3.6% , P <0.001 和 7.3 ±1.5 对 4.9 ±1.9, P <0.001 分别地) 。而且,浆液 homocysteine 层次被发现断然与大动脉的僵硬索引被相关,在浆液 homocysteine 的大动脉的膨胀性和层次之间有否定关联(r = 0.674, P <0.001;r =− 0.602, P <0.001,分别地) 有在 L-dopa 治疗下面的 PD 的 .ConclusionsThe 病人增加了大动脉的僵硬并且与健康个人相比损害了心脏舒张的功能。提高的浆液 homocysteine 层次可以是可能的 pathophysiological 机制。Zeki Yuksel Gunaydln Fahriye Feriha Ozer Ahmet Karagoz Osman Bektas Mehmet Baran Karatas Ash Vural Adil Bayramoglu Abdullah Celik Mehmet Yaman 2016Journal of Geriatric Cardiology2016,13,1:3
4Structure-based design of conformationally constrained cyclic peptidomimetics to target the MLL1-WDR5 protein–protein interaction as inhibitors of the MLL1 methyltransferase activity显示文摘We described herein structure-based design,synthesis and evaluation of conformationally constrained,cyclic peptidomimetics to block the MLL1-WDR5 protein–protein interaction as inhibitors of the MLL1 histone methyltransferase activity.Our study has yielded cyclic peptidomimetics with very high binding affinities to WDR5(Kivalues <1 nmol/L) and function as antagonists of the MLL1 histone methyltransferase activity.Hacer Karatas Shirley Y.Lee Elizabeth C.Townsend Fang Cao Jing Xu Denzil Bernard Liu Liu Yali Dou Shaomeng Wang 2015Chinese Chemical Letters2015,26,4:3
5Inappropriate use of digoxin in patients presenting with digoxin toxicity显示文摘尽管有它的狭窄的治疗学的索引和毒性, BackgroundDigoxin 遗体今天广泛地使用了。学习是调查异羟基洋地黄毒苷的不恰当的使用和老病人的长期的结果的百分比的这的目的就医了因为异羟基洋地黄毒苷 toxicity.MethodsThe 学习包括了为异羟基洋地黄毒苷毒性就医的 99 个连续病人。如果参加者压抑左室的收缩功能,为异羟基洋地黄毒苷的不恰当的使用的另外的学习标准被考虑(喷射部分 <45%) 不在包括贝它块和 angiotensin-converting-enzyme 禁止者治疗的最佳的医药治疗上或如果参加者有永久 AF 尽管有它的狭窄的治疗学的索引,不在最佳的贝它块 therapy.ResultsAppropriate 异羟基洋地黄毒苷用法上的人,在 33 个病人被证实。99 个病人中的 16 个的一个总数死了,与 22.1 ± 的一吝啬的后续时间;10.3 months.ConclusionsContrary 到流行信仰,不恰当的异羟基洋地黄毒苷用法的率仍然保持高。由于它的狭窄的治疗学的索引和毒性,异羟基洋地黄毒苷应该根据当前的证据和指南更小心地被使用。Mustafa Adem Tatlisu Kazim Serhan Ozcan Baris Gungor Ahmet Zengin Mehmet Baran Karatas Zekeriya Nurkalem 2015Journal of Geriatric Cardiology2015,12,2:2
6经角巩膜隧道不作放射状切开的青光眼小梁切除术(英文)显示文摘目的:讨论经角膜巩膜隧道所行的穿透性小梁切除术治疗青光眼。方法:最近有学者报道了五种不同类型的经角膜巩膜隧道小梁切除术,术中不需行放射状巩膜切开。其中三种术式通过与标准Cairns小梁切除术进行比较作对照研究。结果:与标准Cairns小梁切除术相比,经角巩膜隧道所行的小梁切除术术后并发症发生率明显降低,而手术成功率则不低于标准凯恩斯小梁切除术。结论:非放射状巩膜切开经角巩膜隧道小梁切除术较标准Cairns小梁切除术安全性好,而手术成功率相当。Avinoam Ophir Muge Karatas 2004国际眼科杂志2004,4,1:2
