Introduction Signal intensity uniformity in a magnetic resonance (MR) image indicates how well the MR imaging (MRI) system represents an object. One of the major sources of image non-uniformity in high-field MRI scanners is inhomogeneity of radio-frequency coil. The aim of this study was to investigate non-uniformity in head, head and neck, and body coils and compare the obtained results to det...

ovarian follicle response and corpus luteum formation following induction of ovulation using gonadotropin-releasing hormone (gnrh) analogues and luteinizing hormone (lh) in bactrian camel were characterized. bactrian camels with a mature follicle (13-19.6 mm) received: 1) natural porcine lh (25 mg, iv, n = 4), 2) buserelin (20 μg, iv, n = 4) and 3) alarelin (25 μg, im, n = 4). daily ultrasonogr...

increasing water distribution uniformity in micro irrigation systems has been an important subject in applied researches. despite considerable progress in emitters’ construction, some research reports refer to their incapability in water distribution uniformity. in order to achieve greater uniformity in micro irrigation, it is necessary to manufacture emitters with low variation in manufacturin...

system evaluations were performed on 48 center pivots in different parts of saudi arabia. these systems, located on different farms in four different regions of the country, namely: riyadh, jouf, qassim and eastern regions, were evaluated to study the effect of lateral configuration on water application uniformity as regards the original vs. modified laterals. lateral configuration modification...

With rising incidence and emergence of effective treatment options, the management of hepatocellular carcinoma (HCC) is a complex multidisciplinary process. There is still little consensus and uniformity about clinicopathological staging systems. Resection and liver transplantation have been the cornerstone of curative surgical treatments with recent emergence of ablative techniques. Improvemen...

In cite{Kats84}, Katsaras introduced a method for constructing a Hu-tton $[0,1]$-quasi-uniformity from a crisp uniformity. In this paper we present other different methods for making this based mainly in the concept of a fuzzy uniform structure. Furthermore, we prove that some of these methods preserve the completeness property of the quasi-uniformity.  Moreover, we also show that Katsaras' con...

Chemical Vapor Deposition (CVD) is one of the most important methods for producing Carbon Nanotubes (CNTs). In this research, a numerical model, based on finite volume method, is investigated. The applied method solves the conservation of mass, momentum, energy and species transport equations with aid of ideal gas law. Using this model, the growth rate and thickness uniformity of produced CNTs,...

due to the scarcity of water resources, the need for sustainable development of drip irrigation tape is essential in iran. a number of drip irrigation tape systems used in sugar beet fields of isfahan and chahar mahal va bakhtiari provinces were evaluated and were compared with furrow irrigation methods in two consecutive years. the actual water use efficiency (wuesy, wuewsy) in lower quarter, ...
