| 1 | Microbiologic spectrum of acute and chronic dacryocystitis显示文摘AIM:To report the microbiological spectrum of acute and chronic dacrocystitis.METHODS:Retrospective study on 100 patients who presented to the ophthalmic plastic clinic of a tertiary eye care center from May 2011 and April 2013 with acute and chronic dacryocystitis was reviewed for demographic and microbiological profile. The culture results and organisms isolated were recorded.RESULTS:Sixty patients had acute onset and the remaining 40 patients had chronic onset dacryocystitis.The female to male ratio was 1.78. The mean age of patients was 44 y. Gram-positive organisms were the most commonly isolated accounting for 54%, and the commonest species isolated was S. aureus in 26%.Percentage of gram positive cultures was higher in chronic dacryocystitis than acute ones(82% vs 48% of positive cultures; P =0.003). Also in culture positive acute dacryocystitis, gram negative species were found in 52%of eyes but only in 18% of chronic dacryocystitis.CONCLUSION:Gram negative bacteria, culture negative samples, unusual and more virulent organisms are more common in acute dacryocystitis than chronic ones. The results of this study have significant bearing on the treatment of patients with dacrocystitis. | Bahram Eshraghi Parisa Abdi Mohammadreza Akbari Masoud Aghsaei Fard | 2014 | International Journal of Ophthalmology(English edition)2014，7，5： | 11 |
| 2 | Accumulation of heavy metal in Platanus orientalis, Robinia pseudoacacia and Fraxinus rotundifolia显示文摘Plants are capable of reducing environmental pollutions through uptaking contaminants in their tissues. In the study site, twenty one-year-old leaves and shoots as well as twenty soil samples were sampled and analyzed by Inductively Coupled Plasma (ICP). We investigated the uptaking ability of lead (Pb) and cadmium (Cd) by the leaves and shoots of Platanus orientalis, Robinia pseudoacacia and Fraxinus rotundifolia in Karaj city, the western Tehran, Iran. We also evaluated the total metal accumulation capacity by using metal accumulation index (MAI). Results indicated that there was no significant difference in uptaking contents of Cd and Pb in the leaves among the trees. However accumulation of Cd in shoots of F. rotundifolia and R. pseudoacacia was significantly higher than that of P. orientalis. The accumulation of Pb in shoots of R. pseudoacacia was significantly higher than the other species. The amount of Pb in the soil of the study area was significantly higher than Cd. Concentrations of Cd and Pb in leaves of the three species are in the ranges of 2.4 2.7 mg Kg-1 and 7.1 14.4 mg Kg-1 , respectively. R. pseudoacacia had the highest MAI value for leaves (2.21) and F. rotundifolia had the highest MAI value for shoots (2.4). | Sajjad Hosseinzadeh Monfared Mohammad Matinizadeh Anoushirvan Shirvany Ghavamedin Zahedi Amiri Reza Mousavi Fard Fariba Rostami | 2013 | Journal of Forestry Research2013，24，2： | 5 |
| 3 | Humidity sensing properties of Ce-doped nanoporous ZnO thin film prepared by sol-gel method显示文摘The humidity sensitive characteristics of the sensor fabricated from Ce-doped nanoporous ZnO by screen-printing on the alumina substrate with Ag-Pd interdigital electrodes were investigated at different sintering temperatures.The nanoporous thin films were prepared by sol-gel technique.It was found that the impedance of the sensor sintered at 600 oC changed more than four order of magnitude in the relative humidity(RH) range of 11%-95% at 25 oC.The response and recovery time of the sensor were about 13 and 17 s,respectively.The sensor showed high humidity sensitivity,rapid response and recovery,prominent stability,good repeatability and narrow hysteresis loop.These re-sults indicated that Ce-doped nanoporous ZnO thin films can be used in fabricating high-performance humidity sensors. | Mansoor Anbia Seyyed Ebrahim Moosavi Fard | 2012 | Journal of Rare Earths2012，30，1： | 5 |
| 4 | Humidity sensing properties of La^(3+) and K^+ co-doped Ti_(0.9)Sn_(0.1)O_2 thin films显示文摘The humidity sensing properties of La3+ and K+ co-doped Ti0.9Sn0.1O2 thin films were investigated. The humidity sensitive thin films were prepared by sol-gel method on alumina substrates. The sensing behaviors of thin films were inspected at different sintering temperatures by constructing a humidity-impedance measuring system. It was found that the addition of rare earth ion La3+ and alkali ion K+ was beneficial for improving the humidity sensitive properties of the samples and La0.003K0.5Ti0.9Sn0.1O2 sintered at 500 ℃ for 4 h showed the best humidity sensing properties. The impedance of this thin film decreased from 109 to 104 Ω with excellent linearity in the humidity range of 11%-95%. Narrow hysteresis loop, prominent stability and high sensitivity were obtained. The effects of dopant con-tent and doping mechanism on humidity sensitivity were also discussed in terms of segregation of rare earth ions at grain boundaries and granularity of crystalline and influence of K+ on the decrease in the intrinsic resistance of the materials, and increase in the number of wa-ter adsorption sites. | Mansoor Anbia S.E Moosavi Fard | 2011 | Journal of Rare Earths2011，29，7： | 2 |

| 14 | Performance of passive and reactive profiled median barriers in traffic noise reduction显示文摘Median noise barriers, like parallel noise barriers, can be employed to reduce the impact of traffic on roadside communities via the direct propagation path. The performance of different shapes of median barriers was compared using reactive and passive surfaces and a 2D boundary element method (BEM). In the case of reactive surfaces, quadratic residue diffusers (QRDs) and primitive root diffusers (PRDs) were used on the top and stem surfaces of median barriers. To introduce passive barriers, two different absorbent materials including fibrous material and a grass surface with flow resistivity of 20 000 and 2500 kg/(s·m2), respectively, were similarly applied. The effect of thin absorptive barriers was similar at lower frequencies and better at mid and high frequencies to that of their equivalent rigid barriers. More improvement was achieved by covering the top surface of thick barriers with grass rather than with fibrous material. The performance of QRD and PRD barriers where the diffuser was located on the top surface was more frequency dependent than that of barriers coated with fibrous material. A comparison of the average A-weighted insertion loss in the thick barriers showed that the greatest improvement (2.59 dB (A)) was achieved using a barrier of 30-cm thickness covered with grass. | Mohammad Reza MONAZZAM Samaneh Momen Bellah FARD | 2011 | Journal of Zhejiang University-Science A(Applied Physics & Engineering)2011，12，1： | 1 |
