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）.

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.

Stochastic framework for reliability enhancement using optimal feeder reconfiguration

引用

Journal of Systems Engineering and Electronics 2014年第5期25卷 901-910页

作者： Abdollah Kavousi-fard Taher Niknam Mohammad-reza Akbari-Zadeh Bahram Dehghan Nourabad Mamasani Branch Islamic Azad University Electronic and Electrical Department Shiraz University of Technology

Optimal distribution feeder reconfiguration （DFR） is a valuable and costless approach to increase the load balance, reduce the amount of power losses, and improve the voltage of the buses. In this way, this paper aims to investigate the optimal DFR strategy as a proper tool to improve the reliability of the radial distribution networks. The idea of failure rate reduction is employed to see the effect of feeder current reduction on the reliability of the system more accurately. The objects to be investigated are system average interruption frequency index （SAIFI）, system average interruption duration index （SAIDI）, average energy not supplied （AENS） and total active power losses. The problem is then formulated in a stochastic framework based on the point estimate method （PEM） to handle the uncertainty effects. The feasibility and satisfying performance of the proposed method is examined on a standard IEEE test system.

·AIM:To report the characteristics and clinical presentations of retinoblastoma in a series of pediatric patients from Iran. ·METHODS:In this retrospective study, profiles of pediatric patients with retinoblastoma archived in a referral eye hospital in north-west of Iran during 7 years (n =40 patients with 57 eyes) were reviewed. Demographics, as well as the laterality, clinical manifestations and the types of treatment were the major endpoints. The Student’s t test, Mann-Whitney U -test, Chi-square or Fishers’ Exact test was used for analysis where appropriate. ·RESULTS:There were 23 cases (57.7%) with unilateral and 17 cases (42.5%) with bilateral involvement. The male to female ratio was 1 to 1.4 with a mean admitting age of 24.0±11.3 (range:5-62) months. The mean diagnosis delay was (7.4±9.6) months (range:10 days to 13 months). The most common presenting sign was leukocoria (97.5%) followed by proptosis (7.5%), strabismus (7.5%), hyphema (5%), orbital cellulitis (5%) and glaucoma (2.5%). Enucleation was performed in 95.7% of the cases with unilateral involvement and at least one eye of the patients with bilateral disease. A second enucleation was performed in other 3 patients (17.6%) of the latter group. ·CONCLUSION:This is the first study evaluating a series of Iranian children with retinoblastoma.

Lower Cretaceous Shurijeh–Shatlyk Formations host some of the main reservoirs in the Kopeh Dagh-Amu Darya Basin.Exploration in this area so far has focused on the development of structural traps, but recognition of stratigraphic traps in this area is of increasing importance. Integration of 3D seismic data with borehole data from thirteen wells and five outcrop sections was used to identify potential reservoir intervals and survey the hydrocarbon trap types in the East Kopeh Dagh Foldbelt(NE Iran). Analyses of horizontal slices indicated that the lower Shurijeh was deposited in a braided fluvial system.Generally, three types of channel were identified in the lower Shurijeh Formation: type 1, which is low-sinuosity channels interpreted to be filled with non-reservoir fine-grained facies;type 2, which is a moderately sinuous sand-filled channel with good prospectively;and type 3, which is narrow, high sinuosity channel filled with fine-grained sediments. Results indicate that upper Shurijeh–Shatlyk Formations were deposited in fluvial to delta and shallow marine environments. The identified delta forms the second reservoir zone in the Khangiran Field. Study of the stratigraphic aspects of the Shurijeh succession indicates that both lower and upper Shurijeh reservoirs are stratigraphic reservoir traps that improved during folding.

This research was conducted to evaluate the sustainability of rice production using fuzzy logic in Mazandaran province,Iran.The untapped use of modern agricultural technology,such as agricultural machinery,has become a global dilemma,which has forced governments and environmentalists to take a serious stand against the dangers of massive non-standard agricultural practices in the environment.Three types of mechanization,socioeconomic,and economic modeling were used to determine the sustainability and their values were collected through interview method using a 320-item questionnaire from 2016 to 2018.Land evaluation was carried out using soil and climate characteristics,so that about 27.4%of the area was in the perfectly suitable range(S1),35.2%in the appropriate range(S2),19.5%in the critical range(S3),and 17.9%in the inappropriate range(N)for rice cultivation.Farmers were selected from two regions(R1 and R2)by the GIS on two lower levels and more than one hectare(A1,A2)according to agricultural methods(mechanical and traditional).The results showed that the highest and lowest means of the product were 4314.44 and 3501.95 kg ha1,respectively.The sustainability of production was within the range of“sustainability”and“almost sustainable”in terms of mechanistic and economic factors in the fuzzy range of“moderate sustainability”and also with respect to social factors that are in a better position than mechanistic and economic indicators.Results of final sustainability model showed that the average of the lasting sustainability index was in the range of“almost unsustainable”and“moderate sustainability”.

Purpose Traumatic hemorrhagic shock is a life-threatening event worldwide.Severe brain trauma accompanying femoral fractures can trigger inflammatory responses in the body and increase pre-inflammatory cytokines such as TNF-α,IL-1.The primary treatment in these cases is hydration with crystalloids,which has both benefits and complications.The purpose of this study was to investigate the effects of fluid therapy on the hemodynamics,coagulation profiles,and blood gases in such patients.Methods In this cross-sectional study,patients were divided into two groups:femoral fracture group and non-femoral group.The hemodynamic status,coagulation profile,and blood gases of patients in both groups were evaluated upon arrival at the hospital and again 2 h later.Data were analyzed by t-test and ANOVA with repeated data and paired samples t-test.Results A total of 681 trauma patients(605 men and 76 women)participated in this study,including 69(86.3%)men and 11(13.8%)women in femoral fracture group and 536 men(89.2%)and 65 women(10.8%)in non-femoral group.The laboratory parameters were evaluated in response to the equal amount of crystalloid fluid given upon arrival and 2 h later.Blood gases decreased in the fracture group despite fluid therapy(p<0.003),and the coagulation profile worsened although the change was not statistically significant.Conclusion The treatment of multiple-trauma patients with femoral bone fractures should be more concerned with the need for the infusion of vasopressors such as norepinephrine.If there is evidence of clinical shock,excessive crystalloid infusion(limited to 1 L)should be avoided,and blood and blood products should be started as soon as possible.
