We studied effects of NO-donor iron nitrosyl complex with N-ethylthiourea ligand (ETM) on normal or tumor-derived cell lines. ETM was mildly toxic to most cell lines studied except the human glioma cell line A172 that proved to be highly sensitive to the complex and underwent cell death after ETM exposure. The high susceptibility of A172 cells to ETM was attributed to its NO-donor properties si...

This study describes the parcel-based classification of agricultural crops using multi-date Landsat 7 ETM+ images acquired in May, July, and August 2000. The study area is located in North-West of Turkey with an area of about 170 km and grows a variety of crops. The objective was to map the summer (August) crops within the agricultural land parcels. The classification methodology is based on a ...

soil salinity is one of the main environmental problems affecting extensive area in the world. there are some problems with traditional data collection methods for soil studies. using the new methods and techniques such as remote sensing could overcome most of these problems. however using these data in areas with uncommon usages needed some researches to find the best calibration between the d...

Locally computed statistics of image texture and a case-based reasoning (CBR) systemwere evaluated for mapping of forest attributes. Cluster analysis was preferred to regression models, as a pre-selection method of features. The best stand-based accuracy using satellite sensor images was 74.64 m 3 ha 1 (36%) RMSE for stand volume, 1.98 m 3 ha 1 a 1 (49%) for annual increase in stand volume, whe...

Vegetation index (NDVI) was extracted from bi-temporal multispectral images based on the data obtained from Landsat ETM + on 14 th , September, 2000 , Landsat ETM + on 9 th , September, 2004 , Landsat ETM + on 15 th , May, 2008 and Landsat-8 on 21 st , May 2013 for Dangshan County in Anhui Province. Analysis and data extraction was carried out using the ENVI 5.0 software. Normalized values of t...

One of the most important parameters to develop and manage urban areas is appropriate selection of land surface to develop green spaces in these areas. In this study, in order to identify the most appropriate sites and areas cultivated for ornamental species in Jiroft, Landsat Enhanced Thematic Mapper Plus (ETM+) images due to extract the most important effective climatic and adaphic parameters...

abstract solitary pulmonary nodule (spn) is explained as a separate, well-determined obscurity with the maximum size of 3cm which is enclosed by typical lung tissue and is not related to any other anomalies in the lung or adjacent lymph nodes. among imaging modalities mri has more benefits such as high spatial resolution and usage of nonionizing radiation, however, the efficacy of this imaging ...

In this paper we introduce a new procedure for classification and change detection by the integration in a fusion process using hybrid DSmT model, both, the contextual information obtained from a supervised ICM classification with constraints and the temporal information with the use of two images taken at two different dates. Secondly, we have proposed a new decision rule based on the DSmP tra...

Vegetation health can be monitored using a time series of remotely sensed images by calculating the Normalized Difference Vegetation Index (NDVI). We assessed temporal trends throughout an NDVI time series with three sensors: Advanced Very High Resolution Radiometer (AVHRR), the Moderate Resolution Imaging Spectroradiometer (MODIS) and Landsat Thematic Mapper/Enhanced Thematic Mapper Plus (TM/E...
