In this research, in order to investigate the effect of short and long term observational data on the quality of predicting climate parameters, the LARS-WG6 statistical downscaling model is performed for EC-EARTH model and the optimistic scenario RCP4.5 and the pessimistic scenario RCP8.5. Also the HadGEM2-ES model with the optimistic scenario RCP2.6 and the moderate scenario RCP4.5 and the opt...
OBJECTIVE Primary liver cancer (PLC) is a serious disease with high mortality. During the last decade, improvements in the diagnostic procedures and treatment of PLC may have improved survival. However, few updated longitudinal studies examined this issue. In a population-based setting, we studied changes in the prognoses over time. METHODS Between 1998 and 2009, we identified all patients wi...
In this research, we used the support vector machine (SVM), support vector machine combine with wavelet transform (W-SVM), ARMAX and ARIMA models to predict the monthly values of precipitation. The study considers monthly time series data for precipitation stations located in Hamedan province during a 25-year period (1998-2016). The 25-year simulation period was divided into 17 years for t...
AIM To observe the tendency of decreased prevalence of H pylori infection in a 14 year-period and observe the prevalence of intestinal metaplasia and gastric cancer. METHODS All patients who were diagnosed with dyspepsia and underwent esophagogastroduodenoscopy in Cikini hospital Jakarta from January 1998 until December 2005 were evaluated. We evaluated the histopathologic result of H pylori,...
This study aimed to evaluate the effects of Hana’s dam (constructed in 1996) on land use and cover changes using Landsat satellite images. Three images over 35 years (taken in 1976, 1998, and 2011) were obtained and geometric, atmospheric and topographic corrections were applied. The dam’s affected area was selected based on the interpretation of satellite imagery and local expert knowledge. Ma...
in this study, application ofweap model (soil moisture method) have been investigated for simulating hydrological behavior in ahar-chai basin. according to the development of pressurized irrigation systems in this basin, since 2005, two models were carried out for two periods, pre-pressurized period (1998-2006) and pressurized period (2006-2013). irrigation method in first model was surface irr...
I studied the population structure and dynamics of the collared lemming, Dicrostonyx groenlandicus Traill, on Traill Island (NE Greenland) in 1998 to 2000. This is the first comprehensive study of a Greenlandic collared lemming population. During this period, population density continuously declined ( 100 fold-decrease) from more than 10 ind/ha (peak year 1998) to less than 0.1 ind/ha (low year...
One of the fundamental issues about the Iranian economy is the lagging behind of the economic aspirations of the Revolution and the Islamic Republic. One of the explicit ideals is the Islamization of the economic system. What is expected of a government is to move toward its goals. Have the governments established in the Islamic Republic acted towards achieving Islamic goals in the economy? Thi...
