In this research, amount of evaporation and transpiration and water requirement of wheat plant for Marvdasht town (representation station: Zaraghan) during 17-years statistical duration from 1989-2005 and properties of plant and soil are calculated using CROPWAT software. At the first, trends of dry and wet periods for mentioned station were determined using long-term average of climatic data (...

in this paper by using the data related to the monthly precipitation of 13 stations situated in west azerbaijan province of iran in a time period of 34 years, monitoring and forecasting the probability of a drought occurrence is evaluated in next coming months. in this process, first the monthly precipitation amounts for each rainfall station are used in order to calculate the standardized prec...

In this study, an artificial neural network (ANN) based model for prediction of solar energy potential in Kuala Lumpur, Malaysia was developed. Standard multilayered, feed-forward, back-propagation neural networks were designed using Microsoft Excel (MS Excel). The meteorological data were acquired from Malaysia Meteorological Department. The data was consists of meteorological data from one st...

This research presents a case study of the biases and discontinuities that were introduced in observed long-term mean wind-speed gust data-series due to anemometer changes meteorological station northern Spain, operated by Spanish State Meteorological Agency: San Sebastian-Igueldo. Field wind-tunnel experiments with predefined conditions have been presented literature, however this uses real as...

Background: Harvest of hematopoietic progenitor cells via leukapheresis is being used increasingly for autologous transplantation. Adequate yield per kilogram body weight recipient required a successful engraftment. Collection efficiency (CE) useful parameter to assess quality peripheral blood stem cell (PBSC) collection program. In this study, we report 25-year experience in tertiary care Hosp...

Oil concentration (OC) in canola (B. napus L.) is determined during seed fillingperiod (SFP), and the variation in OC is greatly related to environmental conditionsduring that period. To determine factors affecting OC in canola, 12 fieldexperiments were conducted at Agricultural Research Station of Gonbad, Iran,during 2000-07. The experiments were carried out under different growingconditions. ...

one of the most appropriate approaches for flood forecasting is using peak discharge data of hydrometric stations in each region. however, lack of such stations or short duration of data in most parts of the country, make it necessary to use some alternative methods in order to estimate the flood discharge properly. one of these approaches is regional flood analysis method that in a region usin...
