In the treatment of superficial lesions with 8-13 MeV electrons, lead shields are often used to protect the underlying tissue. Measurements were made with film and ion chamber to analyse various aspects of external and internal shielding in electron beam therapy. Data were obtained on the thickness of lead required for shielding, the effect of blocking on dose-rate, electron-backscattering from...

The main aim of this study was to investigate the relationship of students' social capital components and entrepreneurship intention. The statistical population of this study consisted of all students of University College of Agriculture and Natural Resources, University of Tehran (N=2600) among which 155 students where accessed based on Cochran formula and through convenient sampling. Data wer...

S Three new test statistics are introduced for correlated categorical data in strati ed R C tables. They are similar in form to the standard generalized Cochran-Mantel-Haenszel statistics but modi ed to handle correlated outcomes. Two of these statistics are asymptotically valid in both many-strata (sparse data) and large-strata limiting models. The third one is designed speci cally for the man...

Dendropsophus branneri is a small treefrog largely distributed throughout the Tropical Atlantic and Caatinga morphoclimatic domains (see Ab'Sáber 1977 for morphoclimatic domains), from northeastern to southeastern Brazil [Lutz 1973, Frost 2014; see Zina et al. 2014 for taxonomic comments on D. minusculus (Rivero, 1971) and D. branneri]. This species is currently placed in the D. microcephalus s...

1053-5888/09/$25.00©2009IEEE IEEE SIGNAL PROCESSING MAGAZINE [53] JANUARY 2009 W aveform-agile sensing is motivated by the improvements in performance that can result when the transmitted waveform is dynamically tailored to match the sensing objective and the environment. Waveform agility in active radar systems can provide performance improvements such as reduced target-tracking error, improve...

The world needs to sustainably grow more food feed the growing population of planet. Data-driven agriculture is a promising technique that can help farmers be productive, reduce costs, and enable adoption sustainable agricultural practices. However, data-driven limited by lack affordable technologies, for broadband, sensing, imaging, insights. In this article, we present an overview Project Far...

Internet of Things (IoT) technology makes all areas human life more comfortable. The development farms through the use IoT positively influences agricultural production not only by strengthening it, but also making it profitable and reducing cost production. goal this paper is to offer a new IoT-based smart agriculture system that helps farmers get real-time data such as (temperature, humidity,...

UNLABELLED The purpose of this study was to prospectively determine whether combined MRI and (18)F-FDG PET is more accurate than MRI in assessing nonbenign uterine smooth muscle tumors (USMTs). METHODS Seventy patients (mean age, 49+/-10 y; range, 28-77 y) suspected of having nonbenign USMTs underwent both MRI and (18)F-FDG PET before surgery. Results were evaluated using receiver-operating-c...
