This is a study of modeling urban environments from TM satellite images. Urban environments are so heterogeneous. It is necessary to simplify them as combinations of basic land cover materials in order to enable quantitative studies. The V-I-S model proposed by Ridd in 1995 is a conceptual model to simplify urban environments as combination of three basic ground components: vegetation, impervio...
Background: Alkaloids are a group of nitrogen- containing natural compounds derived from a variety of sources including bacteria, fungi, marine organisms and plants. Materials and methods: Fruits, stem or leaves were collected from the Zagros highlands around Azna or Khoramabad city, dried and powdered before being extracted in a soxhalet apparatus. The extract was filtered and concentrated u...
Arasbaran is one of most important regions in terms of agriculture, economics and tourism in northwest of Iran that it usually receives the most yearly spring precipitation. To recognize the synoptic patterns of the 500 hpa, geopotential height data were driven for coordinates 00-70 ˚ E and 15- 65˚N in rainy springs (1972-1976-1979-1981-1986).To select the most important component using princi...
Due to the heterogeneity of existing European sources of observational healthcare data, data source-tailored choices are needed to execute multi-data source, multi-national epidemiological studies. This makes transparent documentation paramount. In this proof-of-concept study, a novel standard data derivation procedure was tested in a set of heterogeneous data sources. Identification of subject...
The design of a high-precision robot assembly system is great challenge. In this article, robotic developed to assemble two components with six degree-of-freedoms in three-dimensional space. It consists manipulators, structured light camera which mounted on the end-effector aside component A measure pose B. Firstly, features irregular are extracted based U-NET network training few labeled image...
Background: Blood transfusion is a relatively common practice in neonatal intensive care units (NICUs). Regarding that few studies have been conducted on infants in neonatal intensive care unit (NICU), this study was investigated the frequency of blood components usage for preterm infants in NICU. Materials and Methods: This study was a cross-sectional descriptive-analytical study and was cond...
Every organization has an identity that is based on organizational culture. Organizations, like individuals, have personality , which is call the culture of that organization. Accordingly, the purpose of this study is to investigate the components of organizational culture in medical universities and present a conceptual model using the Delphi technique. To conduct the research, semi-structured...
