The degradation performance of 11 types of commercially produced degradable starch-polyethylene plastic compost bags was evaluated in municipal yard waste compost sites at Iowa State University (Ames) and in Carroll, Dubuque, and Grinnell, Iowa. Masterbatches for plastic production were provided by Archer Daniels Midland Co. (Decatur, Ill.), St. Lawrence Starch Co. Ltd. (Mississauga, Ontario, C...

OBJECTIVES This study aimed to measure the absorbed doses in selected organs for prospectively ECG-triggered coronary computed tomography angiography (CCTA) using five different generations CT scanners in a female adult anthropomorphic phantom and to estimate the effective dose (HE). MATERIALS AND METHODS Prospectively ECG-triggered CCTA was performed using five commercially available CT scan...

in in order to investigating changes range of oil yield and percentage attention to plant density on three varieties of black seed, an experiment was conducted in the form of factorial based on completely randomized block designs (rcbd) with 4 replications in saat-loui agricultural station of west azerbaijan province. in this research, the first factor (a) contained two levels 20 and 40 cm inte...

Abstract—Thermal insulation materials based on natural fibers represent a very promising area of materials based on natural easy renewable row sources. These materials may be in terms of the properties of most competing synthetic insulations, but show somewhat higher moisture sensitivity and thermal insulation properties are strongly influenced by the density and orientation of fibers. The pape...

PURPOSE To compare in an animal model the image quality of multiplanar reformation and three-dimensional (3D) reconstruction images of the central airways by using single-detector row computed tomography (CT) and multi-detector row CT at varied tube currents and to compare radiation dose. MATERIALS AND METHODS Five dogs each underwent five consecutive helical CT examinations (one single-detec...

OBJECTIVE: We aimed to determine if multidetector-row computed tomography angiography is an effective and non-invasive method for diagnosing anomalous pulmonary venous drainage. MATERIALS AND METHODS: We performed a retrospective review of 2905 cases from July 2003 to November 2007 in which cardiac multidetector-row computed tomography was used. Of the cases, 393 evaluated congenital cardiopath...
