| 1 | DBP formation from degradation of DEET and ibuprofen by UV/chlorine process and subsequent post-chlorination显示文摘The formation of disinfection by-products(DBPs) from the degradation of N,N-diethyl-3-methyl benzoyl amide(DEET) and ibuprofen(IBP) by the ultraviolet irradiation(UV)/chlorine process and subsequent post-chlorination was investigated and compared with the UV/H_2O_2 process.The pseudo first-order rate constants of the degradation of DEET and IBP by the UV/chlorine process were 2 and 3.1 times higher than those by the UV/H_2O_2 process, respectively, under the tested conditions. This was due to the significant contributions of both reactive chlorine species U(RCS) and hydroxyl radicals(HO) in the UV/chlorine process. Trichloromethane, 1,1,1-trichloro-2-propanone and dichloroacetic acid were the major known DBPs formed after 90% of both DEET and IBP that were degraded by the UV/chlorine process. Their yields increased by over 50%after subsequent 1-day post-chlorination. The detected DBPs after the degradation of DEET and IBP comprised 13.5% and 19.8% of total organic chlorine(TOCl), respectively, and the proportions increased to 19.8% and 33.9% after subsequent chlorination, respectively. In comparison to the UV/H_2O_2 process accompanied with post-chlorination, the formation of DBPs and TOCl in the UV/chlorine process together with post-chlorination was 5%–63% higher,Ulikely due to the generation of more DBP precursors from the attack of RCS, in addition to HO. | Ehsan Aghdam Yingying Xiang Jianliang Sun Chii Shang Xin Yang Jingyun Fang | 2017 | Journal of Environmental Sciences2017，29，8： | 3 |
| 2 | Controlled Laser Transformation Hardening of Martensitic Stainless Steel by Pulsed Nd:YAG Laser显示文摘Laser transformation hardening(LTH) was applied to the surface of the AISI 420 martensitic stainless steel by a pulsed Nd:YAG laser to obtain optimum hardness.The influences of process para-meters(laser pulse energy,duration time,and travel speed) on the depth and hardness of laser treated area were investigated.Image analysis of SEM micros-tructure of AISI 420 showed that plate-like carbide have almost fully and(30~40)% of globular carbide particles dissolved into the matrix after laser transformation hardening by pulsed laser and the microstructure was refined to obtain controlled tempered martensite microstructure with 450 VHN hardness. | B.Mahmoudi A.R.Sabour Aghdam M.J.Torkamany | 2010 | Journal of Electronic Science and Technology of China2010，8，1： | 2 |
| 3 | Comparison of accuracy and computational performance between the machine learning algorithms for rate of penetration in directional drilling well显示文摘Oil and gas reservoirs are of the main assets of countries possessing them.Production from these reservoirs is one of the main concerns of engineers,which can be achieved by drilling oil and gas reservoirs.Construction of hydrocarbon wells is one of the most expensive operations in the oil industry.One of the most important parameters affecting drilling cost is the rate of penetration(ROP).This paper predicts the rate of penetration using artificial intelligence and hybrid models on Kaboud oil field well#7 in the directional stage.In this study,different models were constructed through various approaches based on 1878 dataset obtained from drilling operation in the well#7.Then,the accuracy of the constructed models was compared with each other.It was found that the MLP-ABC algorithm predicts the rate of penetration more accurately,by far,as compared with other methods.The MLP-ABC algorithm achieves impressive ROP prediction accuracy(RMSE=0.007211 m/h;AAPD=0.1871%;R^(2)=1.000 for the testing subset).Consequently,it can be concluded that this method is applicable to predict the drilling rate in that oilfield. | Omid Hazbeh Saeed Khezerloo-ye Aghdam Hamzeh Ghorbani Nima Mohamadian Mehdi Ahmadi Alvar Jamshid Moghadasi | 2021 | Petroleum Research2021，6，3： | 2 |

| 9 | Effect of in ovo ghrelin administration on serum malondialdehyde level in newly-hatched chickens显示文摘Objective:To investigate effects of in ovo ghrelin administration on serum malondialdehyde(MDA)level in newly-hatched chickens.Methods:Fertilized eggs were divided into 7 groups:group Tl as control(without injection),group T2(in ovo injected with 50 ng/egg ghrelin on day 5),group T3(in ovo injected with 100 ng/egg ghrelin on day 5),group T4(in ovo injected with 50 ng/egg ghrelin on day 10),group T5(in ovo injected with 100 ng/egg ghrelin on day 10),group T6(in ovo injected with solvent:1%acetic acid,without ghrelin on day 5)and group T7(in ovo injected with solvent without ghrelin on day 10).After hatching,serum MDA concentrations were determined.Results:Chrelin administrated groups(T2,T3,T4 and T5)had lower serum MDA level in comparison with control group(T1)or solvent injected groups(T6 and T7).T2 and T3(ghrelin injection on day 5)had significantly lower MDA concentrations(4.10 and 4.60 nmol/mL,respectively)in comparison with other groups.In T4 and T5,MDA levels were lower than T1,T6 and T7(non-ghrelin administrated groups)(9.53 and 9.50 in comparison with 10.73,10.03 and 10.13 nmol/mL)and were higher than T2and T3.Conclusions:It can be concluded that in ovo administration of ghrelin can have antioxidative protection and reduce serum MDA level.Ghrelin administration on day 5 of incubation is more efficient. | Alireza Lotfi Habib Aghdam Shahryar Yahya Ebrahimnezhad Jalal Shayegh | 2012 | Asian Pacific Journal of Tropical Biomedicine2012，2，1： | 1 |
