102 patients with ascites were enrolled in a sonographic study of abdomen and pelvis without awaring of history, clinical and paraclinical findings. So with only sonographic finding we suggested the diagnosis and etiology of ascites. All patients were hospitalized. Finally all the patients were diagnosed definitely and were compared with sonographic diagnoses done before. Results: In this surve...
Timely and accurate change detection of earth surface features is extremely important for understanding relationships and interaction between human and natural phenomena in order to promote better decision making. Remote sensing data are primary sources extensively used for change detection in recent decades. In this study, images of Landsat (TM) 1985 and Landsat (ETM+) 2007 were analyzed using...
Ecotones are zones of gradual changes from an ecological system to another.Ecotones monitoring could be important to find out the reason for changes and limits. Inthis research satellite data were used to analyze the ecotone boundary in Fars steppicrangelands using IRS LISS III and Pan data of year 2006. The real vegetation map andecotones prepared through Geo-eye images from Google earth softw...
Land use change prediction is an important factor in appropriate planning and integrated ecological management of watersheds. There are various methods for modeling and prediction of land use, i.e. Markov chain and CA Markov. In this research, for predicting the land use of Gareen watershed in Iran in 2042, Landsat satellite images of 1986, 2000 and 2014, and the Markov chain and CA Markov was ...
the present study was conducted to investigate the effect of implicit focus on form through input flooding and the effect of noticing, explicit focus on form on linguistic accuracy. to fulfill the purpose of the study, 86 iranian pre-intermediate efl learners of one of the language institutes were chosen by means of administering ket as the homogeneity test. these learners were pretested throug...

and Applied Analysis 3
We have seen that the accuracy of methods for computing integrals or derivatives of a function f(x) depends on the spacing between points at which f is evaluated, and that the approximation tends to the exact value as this spacing tends to 0. Suppose that a uniform spacing h is used. We denote by F (h) the approximation computed using the spacing h, from which it follows that the exact value is...
