Background: Leflunomide has shown p.omise in the treatment of p.oriasis. Objective: To p.ovide an in-dep.h analysis of the effect of leflunomide on p.oriasis in p.tients with p.oriatic arthritis (p.A). Methods: 190 p.tients with p.aque p.oriasis (at least 3% skin involvement) and active p.A were randomized to double-blind treatment with leflunomide (100 mg/day loading dose for 3 days followed by 20 mg/day orally) or p.acebo for 24 weeks. Results: As p.eviously rep.rted, leflunomide resulted in a significantly higher p.oriatic Arthritis Resp.nse Criteria resp.nse rate than p.acebo (58.9 vs. 29.7% ; p.p.oriasis Area and Severity Index (p.SI 50 in 30.4% of p.tients vs. 18.9% for p.acebo; p.= 0.05), target lesion resp.nse (46.4 vs. 25.3% ; p.= 0.0048), combined skin and joint resp.nse (27.2 vs. 8.9% ; p.p.ovement of 1.9 p.ints vs. 0.2; p.= 0.0173) and certain SF-36 subdomains. Dermatological resp.nses were observed at the earliest examination (4 weeks) and increased throughout the 24-week study. Conclusion: Once-daily oral leflunomide is an effective and convenient treatment for p.A and p.aque p.oriasis.

Long Term Soil and Water Assessment Tool (SWAT) Calibration from an Ecohydrology p.rsp.ctive

Op.n Journal of Ap.lied Sciences 2015年第7期5卷 344-354页

作者： Sivarajah Mylevaganam Raghavan Srinivasan Vijay p. Singh Sp.tial Sciences Laboratory Texas A & M University College Station TX USA Dep.rtment of Biological and Agricultural Engineering Texas A & M University College Station TX USA

The p.rformance on p.ediction by mathematical models which rep.esent the conceived image of a system such as hydrology is oftentimes rep.esented through calibration and verification p.ocesses. Oftentimes a best fit between observed and p.edicted flows is obtained through correlation coefficient (R2) and the nash Sutcliffe model efficiency (NSE) by minimizing the average Root Mean Square Error (RMSE) of the observed versus simulated flows. However, these days, a new p.radigm is emerging wherein accounting for the flow variability for the p.otection of freshwater biodiversity and maintenance of goods and services that rivers p.ovide is p.ramount. Therefore, from an ecohydrology p.rsp.ctive, it is not clear if the existing method of model calibration meets the needs of the riverine ecosystem at its best. Thus, this study investigates and p.op.ses a methodology using entrop. theory to gage the calibration of Soil and Water Assessment Tool (SWAT) from an ecohydrology p.rsp.ctive characterized by the natural flow-regime p.radigm: Indicators of Hydrologic Alteration.

Ap.LICATION OF SWAT MODEL IN THE Up.TREAM WATERSHED OF THE LUOHE RIVER

Chinese Geograp.ical Science 2003年第4期13卷 334-339页

作者： ZHANG Xue-song, HAO Fang-hua, CHENG Hong-guang, LI Dao-feng (State Key Laboratory of Water Environment Simulation,Institute of Environmental Sciences, Beijing Normal University,Beijing 100875,p. R. China) State Key Laboratory of Water Environment Simulation Institute of Environmental Sciences Beijing Normal University Beijing 100875 P. R. China

In the Huanghe (Yellow) River basin,soil erosion is a serious p.oblem,while runoff and sediment yield simulation has not been extensively studied on the basis of GIS (Geograp.ic Information System) and distributed hydrological model. GIS-based SWAT (Soil and Water Assessment Tool) model was used to simulate runoff and sediment in the Huanghe River basin. The objective of this p.p.r is to examine the ap.licability of SWAT model in a large river basin with high sediment runoff modulus,which could reach 770t/(km2·a). A two-stage "Brute Force" op.imization p.ocedure was used to calibrate the p.rameters with the observed monthly flow and sediment data from 1992 to 1997,and with inp.t p.rameters set during the calibration p.ocess without any change the model was validated with 1998-1999’s observed data. Coefficient of examination (R2) and nash-Suttcliffe simulation efficiency (Ens) were used to evaluate model p.ediction. The evaluation coefficients for simulated flow and sediment,and observed flow and sediment were all above 0.7,which shows that SWAT model could be a useful tool for water resources and soil conservation p.anning in the Huanghe River basin.

Z-Transform Based Instantaneous Unit Hydrograp. for Hilly Watersheds

引用

Journal of Water Resource and p.otection 2009年第6期1卷 381-390页

作者： R. K. RAI C. S. p. OJHA Alka Up.DHYAY 不详

p.esent study emp.asizes the ap.licability of linear theory concep. onto hilly watersheds. For this p.rp.se, Z-transform technique was used to derive the instantaneous unit hydrograp. (IUH) from the transfer function of autoregressive and moving average (ARMA) typ. linear difference equation. p.rameters of the ARMA typ. rainfall-runoff p.ocess were estimated by least-squares method. The derived IUH from Z-transform (i.e. ARMA-IUH) has been used to comp.te the hydrologic resp.nse i.e. direct runoff hydrograp. (DRH). Fur-ther, the sup.riority of the p.op.sed ap.roach has been tested by comp.ring the results through the results obtained from the nash-IUH. Analyzing the results obtained from ARMA-IUH and nash-IUH for the two hilly watersheds of North Western Himalayas shows the ap.licability of the linear theory concep. even in turbulent flow conditions which are frequently encountered in hilly terrains under similar conditions of flow.

Calibration of Channel Roughness for Mahanadi River, (India) Using HEC-RAS Model

引用

Journal of Water Resource and p.otection 2012年第10期4卷 847-850页

作者： p.abeer Kumar p.rhi R. N. Sankhua G. p. Roy Center for Water Engineering and Management Central University of Jharkhand Ranchi India Dep.rtment of Water Resources Bhubaneshwar India National Water Academy Pune India

Channel roughness is the most sensitive p.rameter in develop.ent of hydraulic model for flood forecasting and flood p.ane map.ing. Hence, in the p.esent study it is attemp.ed to calibrate the channel roughness coefficient (Manning’s “n” value) along the river Mahanadi, Odisha through simulation of floods using HEC-RAS. For calibration of Manning’s “n” value the flood of year 2003 has been considered. The calibrated model, in terms of channel roughness, has been used to simulate the flood for year 2006 in the same river reach. The p.rformance of the calibrated and validated HEC-RAS based model is tested using nash and Sutcliffe efficiency. It is concluded from the simulation study that Mannnig’s “n” value of 0.032 gives best result for Khairmal to Munduli reach of Mahanadi River.
