Defence Technology（防务技术） 2018年第4期14卷 318-326页

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 *** 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.

Removal of astrazon golden yellow 7GL from colored wastewater using chemically modified clay

引用

Journal of Central South University 2017年第4期24卷 743-753页

作者： meltem CAKMAK Seyda TASAR Veyis SELEN Dursun OZER Ahmet OZER Department of Chemical Engineering Firat University23279 ElazigTurkey

Chemically modified clay(CMC) was used as an adsorbent for the removal of Astrazon Golden Yellow 7GL(AGY-7GL), which is a basic dye from wastewater. For this purpose, the chemically modified clay was first characterized by determining zero point of charge(p Hzpc), and using BET, SEM and FTIR. Then effects of operational parameters on adsorption of AGY-7GL were studied in a batch system. The effect of various parameters such as contact time(0-180 min), pH(2-8), temperature(293-323 K), CMC concentration(0.075-0.5 mg/L) and initial AGY-7GL concentration(75-250 mg/L) were investigated on the adsorption efficiency and capacity adsorption of CMC for the removal of AGY-7GL. Thermodynamic and kinetic parameters were calculated from the results of the adsorption experiment. The evaluation of kinetic models shows that this data best fits the pseudo-second-order model. It is determined that the adsorption equilibrium data works very well with the nonlinear Freundlich isotherm model. Thermodynamic parameters such as ?H^0(19.0 k J/mol), ?G^0(-28.8 k J/mol) and ?S^0(0.148 k J/mol) were also determined. According to the experimental results, it is concluded that CMC could be used as an alternative low cost potential adsorbent for the removal of AGY-7GL from wastewater.

AIM: To evaluate the clinical results, efficacy and safety of Ex-PRESS P200 glaucoma shunt implant in different types of medically uncontrolled glaucoma. METHODS: The study included 31 eyes of 31 patients that were unresponsive to medical antiglaucomatous therapy in whom Ex-PRESS P200 glaucoma shunt implantation was performed. The demographic characteristics of the patients, type of glaucoma, complete ocular examination results, number of antiglaucomatous drugs before and after surgery, early and late complications of surgery, additional surgical and nonsurgical medical interventions, and success rates were investigated from the patients’ files, retrospectively. RESULTS: The mean postoperative follow-up time was 16.4±7.5 mo. The preoperative mean corrected intraocular pressure(IOP) was 28.7±10.3 mm Hg and postoperative mean corrected IOP was 15.3±5.2 mm Hg(P<0.05) at the last visit. The mean IOP reduction was 39.9% when the preoperative and postoperative values of the last visits were compared. The average number of antiglaucomatous drug use decreased from 3.9±0.3 to 1.7±1.7 postoperatively(P<0.05). The use of antiglaucomatous medications at the last visit was more than in other studies in the literature. The most common complication was conjunctival leakage, which was seen in 7 patients. Other early complications were iris touch, intravitreal hemorrhage, hyphema, choroidal effusion, early transient hypotonia and corneal edema. One of the late complications was endophthalmitiswhich was seen in one case 6 mo after the operation, and the other late complication was opacification of the cornea in one patient. Twelve additional surgical operations associated to Ex-PRESS surgery and 3 bleb needling have done. At the last visit, the complete success rate was 32.3% and the qualified success rate was 77.5% in all patients. CONCLUSION: Ex-PRESS P200 glaucoma shunt implantation may be an effective procedure for medically uncontrolled glaucoma with significantly lower use of a
