assessment of the efficiency of s.p.g.c refineries using network dea
data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
MRI after operative reduction for developmental dysplasia of the hip.
We performed MRI on 13 infants after operative reduction for developmental dysplasia of the hip (DDH). Using an axial gradient-echo sequence, MRI accurately depicted the acetabular anatomy and confirmed adequate reduction in 12 patients. The one patient with redislocation after surgery was correctly identified. MRI can be carried out quickly, inexpensively and without risk of radiation and is t...
متن کاملMRI evaluation of rabbit bone marrow after acute irradiation
Background: Magnetic Resonance Imaging (MRI) is a safe modality and useful in characterizing normal and abnormal bone marrow (BM). MRI also presents a more global view of BM than biopsy therefore, it may provide a better understanding of hematologic disorders. The purpose of this study was to monitor radiation-induced alterations of BM in acute phase of irradiation (1-10 day after total body ir...
متن کاملEditorial: CDH or DDH?
not be. It is generally accepted by medical professionals that the manifestation of multigenetic disease during the lifetime of a gene carrier depends on certain environmental factors. This hip disorder can develop and even be exacerbated when certain environmental factors are present, but can also recede without further intervention following elimination of those same factors at an early devel...
متن کاملMore efficient DDH pseudorandom generators
In this paper, we first show a DDH Lemma, which states that a multi-variable version of the decisional Diffie-Hellman problem is hard under the standard DDH assumption, where the group size is not necessarily known. Our proof, based on a self-reducibility technique, has a small reduction complexity. Using DDH Lemma, we extend the FSS pseudorandom generator of Farashahi et al. to a new one. The ...
