| 1 | Semi-hot Stamping as an Improved Process of Hot Stamping显示文摘Reducing the forming load,deletion of springback,increasing the formability of sheets as well as producing high strength parts are the main reasons to apply hot stamping process.Hot stamping process and 22MnB5 steels are the state of the art process and grades,respectively;however novel processes and steel grades are under considerations.In the current research,behavior of the steel grade MSW1200 blanks under semi and fully hot stamping processes was characterized.During semi-hot stamping process,the blank was firstly heated to a temperature of about 650℃ and then formed and quenched in the die assembly,simultaneously.Microstructure and mechanical properties of semi and fully hot stamped blanks were studied and the results were compared with those of normally water/air quenched blanks.The hot stamped blanks attained the strength values as high as water quenched blanks.The highest ductility and consequently,the best formability were achieved for the blank which had been semi-hot stamped.It was concluded that for the mentioned steel,semi-hot stamping process could be considered as an improved thermo-mechanical process which not only guaranteed a high formability,but also led to ultra high strength values. | Malek Naderi Mostafa Ketabchi Mahmoud Abbasi Wolfgang Bleck | 2011 | Journal of Materials Science & Technology2011，27，4： | 15 |
| 2 | Comparison among Ocular Response Analyzer,Corvis ST and Goldmann applanation tonometry in healthy children显示文摘AIM: To explore the relationship between different parameters of Ocular Response Analyzer(ORA) and Corvis ST(CST) in a sample of healthy Iranian school-aged children and the relationship between parameters of these 2 instruments against intraocular pressure(IOP), measured by the Goldmann applanation tonometer(GAT-IOP), age and gender, and find possible correlation between ORA and CST with GAT.METHODS: This cross-sectional study included 90 healthy children. A general interview and complete eye examination were performed. Following successful GATIOP measurement, ORA and CST were conducted. The CST parameters were A 1/2 length(A1 L, A2 L), A 1/2 velocity(A1 V, A2 V), highest concavity deformation amplitude(HCDA), radius of curvature(Ro C), peak distance(PD), central corneal thickness(CCT) and IOP. The ORA parameters were corneal hysteresis(CH), corneal resistance factor(CRF), Goldmann-correlated IOP(IOP-G) and corneal compensated IOP(IOP-CC). Extracted data was analyzed using the Statistical Package for Social Science software.RESULTS: Totally 39 males with age of 9.08±1.60(6-12)y and 51 females with age of 8.96±1.55(6-13)y were included. Many CST parameters were significantly correlated with CH, CRF, IOP-G and IOP-CC. Some CST parameters had a significant correlation with GAT-IOP, including IOP-CST in both eyes and HCDA, A2 L, PD, and RoC in the left eye, but none with age, except A2 L in the right eye. The CRF measurement showed a significant correlation with GAT-IOP in both eyes and CH in the right eye, yet, none with age. Among all CST and ORA parameters, CCT-CST in both eyes and A1 L in right eye had a significant correlation with gender, although this was a negligible negative correlation. Comparison of mean IOP values by different devices showed a significantly highest IOP overestimation by CST and lowest by IOP-CC compared with GAT. Also, IOP-G versus IOP-CST significantly had the lowest IOP overestimation among others. Overall, either low positive correlation or negligible correlation was found between IOP measurements by 3 instruments.CONCLUSION: The study finds the highest IOP overestimation by CST and lowest by IOP-CC compared with GAT. Overall, either low positive correlation or negligible correlation is found between IOP measurements by the 3 instruments. | Ramin Salouti Ali agha Alishiri Reza Gharebaghi Mostafa Naderi Khosrow Jadidi Ahmad Shojaei-Baghini Mohammadreza Talebnejad Zahra Nasiri Seyedmorteza Hosseini Fatemeh Heidary | 2018 | International Journal of Ophthalmology(English edition)2018，11，8： | 4 |

| 6 | Biomass and carbon stocks in three types of Persian oak(Quercus brantii var.persica)of Zagros forests in a semi-arid area,Iran显示文摘Persian oak(Quercus brantii var.persica)is a dominant tree species of Zagros forests in a semi-arid area,western Iran.However,the capacity of biomass and carbon stocks of these forests is not well studied.We selected three types of oak,i.e.,seed-originated oak,coppice oak and mixed(seed-originated and coppice)oak of Zagros forests in Dalab valley,Ilam Province,Iran to survey the capacity of biomass and carbon stocks in 2018.Thirty plots with an area of 1000 m2 were systematically and randomly assigned to each type of oak.Quantitative characteristics of trees,such as diameter at breast height(DBH),height,crown diameter and the number of sprouts in each plot were measured.Then,aboveground biomass(AGB),belowground biomass(BGB),aboveground carbon stock(AGCS)and belowground carbon stock(BGCS)of each tree in plots were calculated using allometric equations.The litterfall biomass(LFB)and litterfall carbon stock(LFCS)were measured in a quadrat with 1 m×1 m in each plot.One-way analysis of variance and Duncan's test were performed to detect the differences in biomass and carbon stocks among three types of oak.Results showed that AGB,BGB and BGCS were significantly different among three types of oak.The highest values of AGB,AGCS,BGB and BGCS in seed-originated oak were 76,043.25,14,725.55,36,737.79 and 7362.77 kg/hm2,respectively.Also,the highest values of LFB and LFCS in seed-originated oak were 3298.33 and 1520.48 kg/hm2,respectively,which were significantly higher than those of the other two types of oak.The results imply the significant role of seed-originated oak for the regeneration of Zagros forests.Further conservation strategy of seed-originated oak is an important step in the sustainable management of Zagros forests in Iran. | Ali MAHDAVI Soghra SAIDI Yaghob IRANMANESH Mostafa NADERI | 2020 | Journal of Arid Land2020，12，5： | 0 |
